Description

Elevator system

The present invention relates to an elevator/elevator system, and in particular to an elevator system having a counterweight for moving the elevator car between two or more different positions.

Traditional elevator or elevator systems are driven by a lifting mechanism that includes cables or hydraulic pistons. In both cases, the system includes an elevator car installed on the platform in the hoistway. The lifting mechanism also exists in the hoistway, and along the guide rail, the guide rail system prevents the car from shaking or deviating from its vertical path.

In the case of a cable system or a traction elevator, a series of metal cables and pulleys connect the elevator car to a motor that lifts the car up or down. Most traction elevator systems have a control room above the hoistway, which houses the motors and pulleys. In some smaller designs, the motors and pulleys are located on top of the hoistway itself. The rope is connected to the elevator car driven by the motor and surrounds the sheave or pulley. The weight of the cabin is balanced by a counterweight located in the hoistway and guided by additional guide rails. The counterweight and various gears help reduce the load on the motor. The elevator car itself is quite heavy, and despite the gears and counterweights, a powerful motor is still required to move the elevator car.

These types of elevator systems also include safety mechanisms in the form of governors and/or electromechanical brakes. The governor ensures that the elevator car does not move too fast by connecting other cables or ropes running on the flywheel and connected to the governor. If the safety rope moves too fast, and/or there is a rapid change in acceleration (ie, the cabin falls), the latch in the mechanism will fly out from the movement change to engage the surrounding ratchet device to stop The ropes in turn stop the elevator car from moving. The electromagnetic brake system prevents movement beyond a specific predetermined position or brakes the system when the power is turned off.

The hydraulic lift includes a fluid reservoir and a piston or cylinder, powered by a pump. The pump system is connected to the motor to raise or lower the cabin from below. The pump, motor, and fluid reservoir are large systems and are located in the space below the cabin in the base of the elevator shaft. This type of elevator is only used for short-distance travel (for example, less than six floors). This is because the size of the cylinder is related to the travel distance. Therefore, high shafts require large pistons. These systems are also quite inefficient compared to traction elevators because they require a lot of energy when lifting the cabin to pump from the fluid reservoir and fill the cylinder with fluid. The safety mechanism in a hydraulic elevator is usually a rupture valve and a manual slack/disconnect cable, which can be connected to a switch to prevent the operation of the elevator.

In both systems, the presence of guide rails (and ropes/weights-in case of demand) in the elevator hoistway limits the cross-sectional area of the elevator car compared to the hoistway. The presence of the control room for the drive mechanism means that the hoistway must be made taller or have additional space to accommodate these parts at the top or bottom of the hoistway (depending on the type of lifting mechanism).

Therefore, there is a need to provide a lifting device and system that addresses at least some of these issues.

Therefore, in the first aspect, the present invention provides an elevator system, which includes: Elevator car, wherein the shape of the cross-sectional area of the elevator car is substantially square with at least one truncated angle; Lifting mechanism, which is configured to raise and lower the elevator car, and Counterweight mechanism, which includes an elongated counterweight hammer, the counterweight hammer is at least a truncated angle adjacent to the elevator car, Wherein, the counterweight has a substantially triangular cross-sectional shape, and is configured to be accommodated in the space defined by one of the at least one truncated angle of the elevator car. The defined space may be bounded between one of the at least one truncated angle of the elevator car and a corner of the hoistway that houses the elevator car. However, the hoistway is not necessarily necessary.

Usually guide shoes, guide rails and rollers are needed to support the counterweight. The counterweight mechanism may include a hoop with a triangular cross-section, and is configured to be connected to the rail bracket to support the movement of the counterweight hammer. The guide rail brackets can be located at various truncated corners of adjacent elevator cars. The opposite guide rail brackets can be arranged along the centerline of the cross section of the elevator car.

The shape of the transverse section of the elevator car may be a substantially quadrangular shape, such as a square or a rectangle with at least one truncated angle. The shape of the elevator car may be substantially square and have a first truncated angle and a second truncated angle.

The lifting mechanism may be located at one of at least one truncated angle adjacent to the elevator car. The lifting mechanism may be located at one of the first or second truncated angle adjacent to the elevator car. The counterweight may be located at the other of the first or second truncated angle of the adjacent elevator car.

The at least one truncated angle may be substantially 30-45 degrees truncated. The elevator car may include a plurality of wall panels. Adjacent wall panels can be configured to form an angle of 135 to 150 degrees with each other and form at least a truncated angle.

Each wall panel is removable and/or replaceable. The elevator car may include removable and/or replaceable floors (or floors) and/or ceilings (or roofs).

At least one of the plurality of wall panels of the elevator car may be removable to form an opening and be selectively closed by a door, thereby providing an access point into the elevator car.

The elevator car may be formed by a frame defining the shape of the elevator car. The frame may include rims attached along various vertical and/or horizontal portions of the frame. The plurality of wall panels may be attached to the edge strip in a removable and/or replaceable manner, such as by clamping the wall panel into the edge strip.

Each of the plurality of wall panels can be formed from a composite material, such as an aluminum honeycomb material.

The present invention is designed to be used in a variety of lifting mechanisms, such as the lifting mechanisms found in traction elevators. The lifting mechanism can be configured to raise and lower the elevator car. The lifting mechanism may include traditional traction methods such as stainless steel ropes or flat belts to raise and lower the elevator car. With such a lifting mechanism, the elevator car can be supported in the center. The lifting mechanism may include a driving mechanism including: a flexible driving member coupled to the elevator car; and a driving means configured to drive the driving member to raise or lower the elevator car.

According to the patent case WO2018073612 published by the applicant, the lifting mechanism may specifically include: An elongated support member, which is located adjacent to the elevator car and has a substantially vertical longitudinal axis; The drive mechanism includes: an elastic drive member that is held longitudinally around the support member; and a drive means configured to drive the member relative to the support member around an axis that is substantially orthogonal to the longitudinal axis.

The lifting mechanism and the supporting member may be located at a truncated angle of the adjacent elevator car, for example, in a space defined between the truncated angle and a corner of the elevator shaft. In such an embodiment, the elevator car can be supported on one side, so that the elevator car is cantilevered.

The driving mechanism may be a positive-drive mechanism. The driving mechanism may be a push-drive mechanism. Additionally or alternatively, the drive mechanism may include a pull-drive mechanism. This can produce a push-pull drive mechanism. The pushing mechanism may further include at least one pulley coupled to the driving member and the driving means.

The driving means may be a motor, such as a gear motor or a gearless motor. Operation in the first direction of the driving means can cause the elevator car to move vertically upward. Operation in the reverse second direction of the driving means can cause the elevator car to move vertically downward. In other words, the operation of the drive mechanism in the first direction can cause the elevator car to move vertically upward relative to the support member; and the operation of the drive mechanism in the opposite second direction can cause the elevator car to move downward relative to the support member Relative movement.

The motor can be located in a groove at the lower end of the elevator hoistway, or in another space in which the system is housed. Alternatively, in the case of a shallow pit under the elevator car or even no pit, the motor may be located above the elevator car, for example adjacent to the door (where the door replaces one or more wall panels), or located The top of the hoistway (if there is one). When the motor is located above the elevator car and not in the well pit, the operator does not need to enter the well pit for maintenance purposes, so the safety risk to personnel is small.

The driving member may include one of stainless steel-plated ropes, chains, and straps. For example, flat belts or V-shaped toothed belts. The drive member may include a continuous ring.

The elevator system may include a single drive member. The counterweight can be connected to a single drive member by any suitable means. Alternatively, the elevator system may include multiple drive members. The total weight of the counterweight can be evenly distributed among the various drive members, for example, by connecting individual (smaller) counterweights to each drive member.

The lifting member can be connected to the base or side of the elevator car. The lifting member is coupled to the driving means so that the operation of the pushing mechanism causes substantial vertical movement of the elevator car relative to the supporting mechanism. The lifting mechanism may be configured to push the elevator car from bottom to top to drive the driving member in the first direction in response to the driving means. Similarly, the lifting member may be configured to guide the elevator down to drive the driving member in the second direction in response to the driving means.

When the driving member is a chain system, the lifting member may include a plate member that is connected to the base or side of the elevator car. The lifting member or panel may include a security fork, which is used to provide a connection between the driving means and the elevator car. The lifting member or panel may also include one or more weighing sensors, which are used to generate electronic signals representing the weight and/or force of the elevator car.

The lifting member or panel may include a layer of shock-proof material adjacent to the base of the elevator car. In addition, each wall panel may include shockproof materials, such as rubber, to minimize vibration and noise in the elevator car.

The support member may include a plurality of substantially parallel vertical beams. The support member may include two pairs of vertical beams, and the drive member may extend longitudinally between the first pair of beams and the second pair of beams. Each beam may include fixed points at intervals along the length of the beam, and the brackets are connected to the fixed points to divide the beams into pairs. Multiple pairs of beams can be interconnected by spaced members located along the length of each beam. At least one beam can be connected to the wall of the elevator hoistway (or other space containing the elevator system) through a fixed bracket.

The system may further include: a plurality of sliding shoes or rollers connected to the base of the elevator car; and a plurality of corresponding shoes or rollers connected to the top surface of the elevator car.

The lifting mechanism may include a safety mechanism to control the movement of the elevator car. The safety mechanism can be connected to one of the wall panels, for example one of the truncated wall panels located in the elevator car.

An elevator system is also described here, which includes: An elevator car, wherein the shape of the cross-section of the elevator car is substantially square with at least one truncated angle; and Lifting mechanism, which is configured to raise and lower the elevator car, Wherein, the elevator car includes a plurality of removable and/or replaceable wall panels.

The shape of the transverse section of the elevator car may be substantially quadrilateral, for example, square or rectangular with at least one truncated angle. The elevator car system can be formed by a frame, such as an extruded aluminum frame. The frame can be completed by water transfer film printing or electroplated polymer. The frame may define the shape of the elevator car. A beading may be attached along the vertical and/or horizontal portions of the frame, for example, on the inner and/or outer surfaces of the vertical and/or horizontal portions of the frame. A plurality of wall panels are removably connected to the edge strip. Each wall panel can be connected to each wall panel by sandwiching (or snapping into) the edge strip. Each wall panel can also be removed from the edge by unfastening each wall panel from the edge.

The frame of the elevator car can be designed to have more than one different type (or shape, such as a cross-sectional shape) of extruded parts, so that the extruded parts together with the rim are tied to provide different angles between adjacent wall panels. For example, 90 degrees or 135 degrees between adjacent wall panels. When the adjacent wall panel is greater than 90 degrees, for example 135 degrees, it can provide the truncated angle of the elevator car.

The frame is the structural feature of the elevator car. The elevator car may also include a removable and/or replaceable floor (or floor) and/or ceiling (or roof). The top and bottom plates can also be structural. The wall panel is not structural, so it can be removed or replaced.

Any one of the plural wall panels of the elevator car can be replaced. At least one wall panel can be removed to form an opening to provide an access point to the elevator car. Advantageously, such an opening can be on at least one side of the elevator car. Each opening can be selectively closed by a door. The wall panel can be removed and replaced with a door stop. One or more wall panels can be replaced with different wall panels, so that the interior of the elevator car can be easily redesigned, such as changing the interior color of the wall panels.

The lifting mechanism may be located at least at a truncated angle of the adjacent elevator car.

The at least one truncation angle may be a truncation angle of substantially 30-45 degrees (providing an angle of 135-150 degrees between adjacent wall panels). The shape of the transverse section of the elevator car is a substantially quadrilateral, for example a square or rectangle with two truncated corners. For example, the first truncated angle and the second truncated angle. The lifting mechanism can be located at the first or second truncated angle of the adjacent elevator car.

The system may further include a counterweight mechanism. The counterweight mechanism can be located at the first or second truncated angle of the adjacent elevator car. The counterweight mechanism may include a counterweight hammer. The counterweight can be of any shape. The counterweight may be elongated and have a triangular cross-sectional shape. The triangular cross-sectional shape may allow the counterweight to be accommodated into the space defined by one of the truncated angles of the elevator car. The defined space is bounded between one of the at least one truncated angle and a corner surrounding the elevator shaft. However, it should be noted that the elevator shaft is not necessarily necessary.

Usually guide shoes, guide rails and rollers are needed to support the counterweight. The counterweight bracket required to support the counterweight blocks at least one wall panel, indicating that it cannot be removed or replaced with a door.

The elevator car can be formed from composite materials. For example, one or more wall panels may be formed from composite materials. One or more wall panels may be formed from aluminum honeycomb material. Beneficially, the honeycomb structure of the material can help to minimize the amount of material used, which in turn helps to minimize the weight and cost of the elevator car.

One or more of the wallboards can include a radio-luminescent layer, which can be found in, for example, organic light-emitting diodes (OLEDs), which can be produced by organic vapor generation printing or inkjet printing. Alternatively, the wallboard may include electroplated polymers. Such a layer may be disposed on the inner or outer surface of one or more wall panels. Beneficially, this approach allows one or more wall panels to be used as digital displays on the inside and/or outside of the elevator car to display images (such as advertisements).

Although the present invention has been described above, the present invention extends to any creative combination with the above-mentioned first aspect or second aspect of the present invention, or the features described in the following, or the drawings.

The term "upward" as used herein will be understood as a stretch or movement from a low position to a relatively high position. The term "downward" used here will be understood as a stretch or movement from a high position to a relatively low position.

Although the following examples include the elevator shaft where the elevator car is located, it is envisaged that such an independent elevator shaft is not necessary, and the present invention can be operated without the elevator shaft.

1 and 2 show the elevator shaft 10 and the elevator car 12. The shape of the cross section of the elevator car 12 is square and has two truncated angles substantially truncated at an angle of 45 degrees: a first truncated angle 17a and a second truncated angle 17b. The cross-sectional area of the elevator car 12 at least fully complies with the European standards outlined in the Disability Discrimination Act of 1995, which emphasizes the importance of having sufficient space for wheelchair activities. The benefit of the increased cross-sectional area may be to provide wheelchair users with a greater area of movement, as presented in the slewing circle depicted in the elevator car shown in FIGS. For example, the slewing ring may have a diameter of 1400 mm, and the width of the door may be 900 mm, thus providing a wheelchair user with sufficient area to enter/exit the elevator car and rotate the ring as needed.

Advantageously, the cross-sectional area of the elevator car 12 is significantly larger than the cross-sectional area of the conventional elevator car with respect to shafts of the same size. A larger cross-sectional area can increase the capacity of the elevator car to, for example, double.

The elevator car 12 includes a plurality of removable and/or replaceable wall panels 14. FIG. 1 shows that one of the wall panels 14 a of the elevator car 12 has been removed to expose the opening 15 into the elevator car 12. The removed wall panel 14 has been replaced by the door 13 and the door stop 13a. The opening 15 is selectively closed by the door 15 and thus provides an access point into the cabin 12. Figure 1 also shows the contour of the door where it can be located, for example, on the opposite side of the current door position; or one of the side wall panels adjacent to the current door position.

The elevator shaft 10 also includes a counterweight mechanism 40, which will be described in more detail later. The counterweight mechanism 40 blocks one side of the elevator car 12, which represents that the wall panel 14 on the rear side or the wall panel 14 on the right side cannot be removed and replaced with a door.

The elevator car 12 includes a plurality of vertical and horizontal extruded aluminum columns (not shown) that create a frame that defines the shape of the elevator car 12. These columns are structural and provide support for the elevator car 12. The floor and ceiling (not shown) of the elevator car are replaceable/replaceable and are also structural.

A rim (not shown) is connected to each vertical post and/or horizontal post. Usually there is a groove of about 12 mm between the inside and outside of the frame of the elevator car, which can accommodate wall panels. The wall panel 14 is clipped or snapped into the edge strip. The structural features of the elevator car 12 (frame and roof/bottom plate) are provided to allow any panel, especially the wall panel, to be a necessary structure that can be removed and replaced.

The frame and the rim are jointly designed to provide a predetermined angle between adjacent wall panels. For example, the extruded portion of the rim can be designed to engage the wall panel at a 90-degree angle (element 16a shown in FIG. 2). In another example, the extruded portion of the rim is designed to engage the wallboard at an angle of 135-150 degrees to provide a 30-45 degree cut-off angle (element 16b shown in FIG. 2). These angles are defined as having a width sufficient to minimize distortion in any elevator car structure.

The elevator cabin 12 is formed of a composite material, such as glass fiber, carbon fiber, or other similar materials. Alternatively, it may be formed by a honeycomb core sandwiched between aluminum sheets or the like. For example, the floor, ceiling and wall panel 14 are formed of aluminum honeycomb material. The door 13 is also formed of a composite material, which reduces weight, for example, 10-15 kg (composite material) from 100 kg (stainless steel door).

Beneficially, composite materials generally have higher strength (eg, about 10 times higher strength) than conventional materials of the same quality, such as stainless steel. This is to allow the elevator car to become lighter while maintaining similar strength. For example, if the average weight per person is 75 kg, the conventional elevator cabin weighs about 1500 kg when carrying 10 people, and the composite material elevator cabin weighs about 900 kg when carrying 10 people.

The elevator car of the present invention can be integrated with a traditional car sling. Beneficially, the embodiments of the present invention with structural frames and lightweight composite panels do not require a cabin sling. This configuration can help reduce the depth of the bottom of the elevator car, thereby helping to minimize the distance that the elevator car extends into the pit at the bottom of the elevator shaft. Therefore, a conventional buffer such as a single point buffer may no longer be required. It is envisaged that a simple cushioning mechanism will suffice, such as an alternative carrier pad. In addition, since the height of the elevator car has been reduced, there is no need for a traditional deep pit. Therefore, the present invention can reduce the thickness of the well pit to about 150 mm or less (depending on the thickness of the wallboard), thereby saving space and ultimately cost. In addition, such a shallow pit usually does not need to be waterproof, because it will not be below the groundwater level, which is different from the conventional well pit.

Beneficially, the elevator car of the present invention requires fewer technicians to manufacture and install, so it can maintain high standards of quality and safety while saving costs. First, the extruded columns and rims need to be assembled to define the shape of the elevator car. Then, you need to use a conventional cutting tool, such as a circular saw, to simply cut the honeycomb panel into the correct shape and size, and then clip it into the edge strip. Shockproof materials such as rubber are also placed on the wallboard to minimize noise and vibration in the elevator shaft. A hole needs to be drilled in the top plate (which is permanently connected to the frame) to allow the pulley system to be installed (if necessary), and the safety gear must also be installed on one of the wall plates and adjacent to the guide rail. The elevator car is now ready to be installed in the elevator shaft.

The elevator shaft 10 also includes a counterweight mechanism 40, as shown in FIG. 1 (top view), FIG. 3 (front view), and FIG. 4 (side view of the counterweight mechanism, the elevator car is not shown). The weight mechanism 40 includes an elongated weight 41 that has a triangular cross-sectional shape. The shape of the counterweight 41 can be clearly seen in FIGS. 1 and 4(A). The counterweight 41 is located in the space defined between the elevator shaft 10 and the second truncated angle 17b. The counterweight 41 has a triangular cross-sectional shape, so that the counterweight 41 can be accommodated by the second truncated angle 17b, and effectively use the available space.

The counterweight mechanism 40 includes a hoop member 43 having a triangular cross section. The rail bracket 42 is connected to the hoop 43 and supports the upward or downward movement of the counterweight 41. Such a hoop/bracket slows down what is usually needed in the art-the need for the technicians required to install a particular counterweight rail.

As seen in FIG. 1, the guide rails 48 are located at the truncated angles of adjacent elevator cars, and are arranged along the center line 46 of the cross section of the elevator car 12. Advantageously, arranging the counterweights in this way allows the elevator car to be easily scaled up or down in cross-sectional dimensions. Therefore, if the car needs a smaller car hoistway, it can easily produce a reduced-scale elevator car without repositioning any components to maintain the stability of the elevator car.

The counterweight 41 can be connected to a single drive member 44. Alternatively, if there are multiple drive members, the weight can be evenly distributed between the drive members so that the counterweight is connected to each drive member. The weight and size of the counterweight depends on the materials used to make the counterweight.

The two truncated corners 17a, 17b are usually used for different purposes. The first truncated angle 17a generally accommodates any electronic component in the elevator system, such as a safety mechanism and any magnetic reading belt (which is used to detect the absolute position of the elevator car). The second truncated angle 17b generally accommodates any mechanical element in the elevator system, such as a counterweight.

The elevator shaft 10 also includes a lifting mechanism, which includes a motor 18. According to the assumption, the lifting mechanism may be a conventional lifting mechanism, such as a traction elevator with stainless steel rope. Alternatively, the lifting mechanism may be the same or similar lifting mechanism described in the applicant's published patent document WO2018073612. Whichever lifting mechanism is used, the lifting mechanism includes drive means in the form of a gear motor or gearless motor; and a flexible drive member coupled to the elevator car. The driving member may include one of stainless steel ropes, chains, and belts, such as flat belts or V-shaped toothed belts. In use, the motor drives the drive member to raise or lower the elevator car in the elevator shaft.

Figure 3 shows the lifting mechanism and counterweight. The lifting mechanism includes: a motor 18 (gear motor or gearless motor); a driving member 44, which allows the traction part to be separated from the suspension part, so that the traction part is connected to the counterweight in a 1:1 ratio and through the pulley, as shown in the figure 4 is shown. The suspension part is connected to various pulleys 47a-47d so that the hoisting machine has a 2:1 rope ratio to reduce the speed of the cabin by half of the rope.

FIG. 4 shows the lifting mechanism and counterweight 41 driven in the forward direction. The lifting mechanism includes: a gear motor or a gearless motor 18; a drive member 44. The counterweight 41 has a triangular cross section as described above. The drive member 44 is directly connected to the motor 18, thus providing a 1:1 traction system. However, the elevator car (not shown) is suspended in a 2:1 configuration by ropes, so the elevator car will move at half the rope speed. This system is a novel system and allows the elevator car to be moved by moving the counterweight.

FIG. 5 shows an embodiment of the patent document WO2018073612, in which the elevator mechanism 120 is located in the space defined by the elevator shaft 110 and the truncated angle 117a, and the elevator car 112 is cantilevered. Except for the part marked with "1" at the beginning, features common to Figs. 1-4 are marked with the same component symbols. These features will not be restated.

As detailed below and in the patent document WO2018073612, the elevator mechanism 120 is a push drive mechanism (one type of positive drive). In this embodiment, the elevator mechanism 120 is located in a space defined by one of the corners of the elevator shaft 110 and the cut angle of the elevator car 112. The elevator mechanism 120 includes driving means, and its form is a gear motor 130. The flexible drive member 144 is also coupled to the elevator car 112 so that in use, the motor 130 drives the drive member 144 to raise or lower the elevator car 112 in the elevator shaft 110. The operation of the motor 130 in the first direction causes the elevator car 112 to move vertically upward, and the operation of the motor 130 in the second direction causes the elevator car 112 to move downward relatively.

Alternatively, the embodiment of the elevator mechanism may be a pull-type drive mechanism.

As shown in FIG. 5, an embodiment of the elevator mechanism 120 includes: two pairs of vertical beams 145; for example, a continuous drive member 144 of a chain, which extends longitudinally between the pair of beams 145, so that the drive member 144 surrounds two pairs when in use The beam 145 rotates.

The gear motor 130 drives the driving member 144 around the pair of beams 145 through a driving pulley (not shown). The motor 130 moves in the first direction (or forward direction) and the second direction (or backward direction). The motor 130 is located below the elevator car 112 in a pit or groove at the bottom of the elevator hoistway 110. Alternatively, it may be located in the top of the elevator shaft 110 above the elevator car.

The depth of the well pit depends on the maximum speed of the elevator car 112, and it is envisaged that the system of the present invention can travel between about 0.15ms ^-1 and 1.6ms ^-1 , and has a shallow layer-such as a 50mm well, as described above pit. Beneficially, such a shallow well pit helps to save the time required to configure the well pit and the area of the well pit (because the well pit is usually located underground, which requires a waterproof structure).

Since the elevator car 112 is much lighter than the conventional elevator car, the motor does not need to provide so much power to drive the driving member 144 to move the elevator car 112 up and down. It is envisaged that the elevator car can be powered by single-phase or three-phase power supplies. For example, single-phase power supplies are usually used in elevator cabins installed in residential environments; and three-phase power supplies are usually used in commercial environments.

The lifting plate 122 is connected to the driving member 144. The lift plate 122 is connected to and below the elevator car 112. FIG. 5 also shows sliding shoes 124, 126 located at the top and bottom of the elevator car 112. The lift plate 122 and the sliding shoes 124 are used to support the elevator car 112 when the elevator car 112 moves up and down in the elevator shaft 110. The sliding shoes 124, 126 help to minimize any lateral or rotational movement of the elevator car 112. The lifting plate 122 itself does not hinder the movement of the elevator car 112 from one side to the other, so it is advantageous to provide the sliding shoes 124, 126 to prevent or at least minimize such movement.

The elevator car 112 is lifted and supported from one side by the lifting plate 122 and the sliding shoes 124, 126. In other words, the elevator car 112 is cantilevered in the elevator car 110. Because the wall of the elevator car 112 is adjacent to the wall of the elevator shaft 110, the elevator car 112 is guided upward and downward in the elevator shaft. This situation is directly in contrast to the conventional elevator system. In the conventional elevator, the elevator car is supported from above along its central axis by a system of ropes, pulleys and counterweights, and by adding The guide rails are guided up and down in the elevator shaft. For example, conventional elevators typically have counterweights that are about 1.5 times the maximum weight limit of this particular elevator car. There must be sufficient space between the wall of the elevator car and the wall of the elevator hoistway to accommodate ropes, pulleys, counterweights and guide rails, and this means that the cross-sectional area of the elevator car is small and its capacity is reduced. Alternatively, the elevator car can be suspended in the center.

In use, in order to move the elevator car 112 from a lower height to a higher height, the motor 130 is activated and rotates in the forward direction. The activation of the motor 130 causes the drive pulley to rotate, which in turn causes the drive member 144 to rotate around the beam 145 in the first direction. Since the motor 130 is a gear transmission type, the power output from the motor 130 is equivalent to the power input to the drive pulley. Therefore, based on such a 1:1 ratio, the initial velocity of the driving member 144 may be about 1.6 m (ms ^-1 ) per second. Subsequently, the lifting plate 122 connected to the driving member 144 is caused to move in the upward direction at the initial speed of 1.6 ms ^-1 . The elevator car 112 is accelerated upward at a rate of 0.6 m (ms ^-2 ) per square second. There is no limit to how fast the elevator car 112 can move or how high it can travel, but it is usually estimated to be about 2.5 ms ^-1 and about 20 floors high. The upward movement of the lift plate 122 pushes the connected elevator cabin 112 from below, so that the elevator cabin 112 moves from a lower height in an upward direction to a higher height. The movement of the elevator car 112 is stabilized by the sliding shoes 124, 126, so that the elevator car 112 does not rotate when pushed up. When the elevator car 112 moves upward, the counterweight moves downward. The downward movement of the counterweight helps to pull the elevator cabin 112 upward. Therefore, the elevator car 112 is pushed up, or, in some embodiments, it is simultaneously pulled up and pushed from a lower height to a higher height.

In addition, in order to move the elevator car 112 from a higher height to a lower height, the motor 130 will first stop and then start to rotate in the backward direction. The driving pulley also stops and rotates in the opposite direction, and this in turn causes the driving member 144 to rotate in the opposite or clockwise direction around the beam 145. Subsequently, the lift plate 122 is caused to move at an initial speed of 1.6 ms ^-1 in the downward direction. The elevator car 112 accelerates downward at a rate of 0.6 ms ^-2 . The downward movement of the elevator plate 122 guides the connected elevator car 112 to move the elevator car 112 from below to a downward direction from a higher height to a lower height. Similarly, the movement of the elevator car 112 is stabilized by the shoes 124, 126, so that the elevator car 112 does not rotate when guided downward. When the elevator car 112 moves downward, the counterweight moves upward. The downward force on the counterweight due to gravity helps to slow down the speed of the elevator car 112 moving downward. The movement of the elevator car 112 (both upward and downward) is guided by the walls of the elevator shaft 110.

The elevator mechanism 120 described here can be used from, for example, a small elevator car with a capacity of 8 persons to a larger elevator car, such as a cargo elevator of 26 tons.

Figure 6 shows a three-dimensional view of the elevator car 212 with: a single truncated angle; and a removable/replaceable wall panel. As can be seen, some preset wall panels formed from composite materials (such as aluminum honeycomb materials) have been removed and replaced with glass or other transparent materials.

Similar to the embodiment shown in FIG. 1, the elevator car 212 can be operated by any suitable lifting mechanism, such as a traction mechanism, or the applicant's own push drive mechanism as described in patent document WO2018073612.

It should be understood that the elevator car may have any cross-sectional shape, as long as at least one cut-off angle of the elevator car is sufficiently cut to accommodate the lifting mechanism and/or the counterweight.

For the avoidance of doubt, the terms "lift" and "elevator" are used interchangeably here. It refers to the platform or compartment in the hoistway, which is used to raise or lower people or objects to different levels.

Although the present invention has been described above with reference to exemplary embodiments, it should be understood that various changes or modifications can be made without departing from the scope of the present invention within the scope of the appended patent application.
