Description

TECHNICAL FIELD The present invention relates to a flip-up type elevator gate installed at, for example, a garage entrance.

[Prior Art] A so-called flip-up type gate is known as a gate close to this type. However, in this gate, a 70 cm length is provided at the upper end position of a pair of relatively low opposing columns that are erected on the left and right. The arm is rotatably fixed to a certain degree, the gate main body is fixed to the arm tip side, and the gate main body is rotated about the above-mentioned pivot fulcrum to open and close by jumping.

[Problems to be Solved by the Invention] However, in this case, since the gate main body is separated from the support by the arm length, an installation space corresponding to the length is required in the front-rear direction. For example, if there is an obstacle such as a flower bed behind the entrance, it will be difficult to install the columns. Also, since the lower end of the gate body draws an arc trajectory back and forth and is jumped up from its fixed position, it is inevitable that a dead space will occur on the front side of the gate, while on the other hand, if a vehicle etc. approaches it, it may not open and close. In addition, there is a risk that the gate body may collide with children and vehicles when opening and closing.

The present invention has been made in view of such conventional problems, and provides a flip-up type elevating gate that has a small installation space, does not cause a fixed dead space, and has no risk of opening and closing operations. To aim.

[Means for Solving the Problems] According to the present invention, in the open state, the gate main body is moved up and down between a pair of columns, and the gate main body is pivotally lifted at the highest position. The present invention is provided with a structure for holding the support horizontally (or in a slanting shape) to open the columns, that is, according to the present invention, between each pair of support shafts projecting close to the longitudinal intermediate positions on both sides. One main shaft for vertical lifting is fixed to one of the support shafts directly or via a slider, and the other support shaft is fixed to the sub-roller for turning and jumping. Single-door main body with two side shafts; main roller and sub roller guide rails are vertically installed in parallel and in parallel with each other. point A lift-up type hoisting gate door characterized by comprising a pair of vertical columns provided with a forward-backward curving upward guide portion for forced rotation of a sub-roller along an arc locus centering on a support shaft position. And this is the gist.

[Operation] In the present invention, the gate main body is always positioned below a pair of vertical columns when the door is closed, and the vertical main post is always positioned as a fixed position. The main roller for vertical lifting reaches the top dead center and the main body of the gate reaches the highest position, and the sub-roller is used for forced rotation of the sub-roller and guided to the forward and backward flip-up guide section by guiding it to the upper position. In addition, the urging force of the urging spring acts as a flip-up force in the rotation direction of the gate main body, and the gate main body is opened horizontally (or inclined) and maintained in that state. On the other hand, by applying a pulling down force against the biasing spring, the gate main body reversely becomes in a vertical state and returns to a fixed position and is closed.

[Embodiment] The present invention will be further described with reference to the drawings showing embodiments. 1 is a flip-up type elevator gate, and this gate 1 is a single aluminum alloy material having a height of 1 m and a lateral width of about 3 m. The gate main body 2 is made of, and left and right vertical columns 17, 17 are paired.

The gate body 2 is supposed to have two shafts with rollers on one side,
A pair of support shafts 4 and 12 are provided so as to project close to the intermediate positions on both sides in the longitudinal direction, respectively. That is, the bracket 3 is fixed to the middle position of the left and right side surfaces of the gate main body 2 in the longitudinal direction so as to project in the front-rear direction, and one of the center shafts at the upper and lower central positions of the gate main body 2 is fixed via the bracket 3. The support shaft 4 and the support shaft 4 are brought close to each other (in this example, the support shafts 4 are brought close to each other at an interval of about 6.5 cm). is there.

A thick-walled rectangular block-shaped slider 5 is fitted on the support shaft 4 of the center shaft to allow the support shaft 4 fixed to the gate main body 2 to freely rotate. Two main rollers 6 for vertically elevating vertically are installed and fixed in a tandem manner at a position sandwiching the support shaft 4 in a pair of upper and lower sides. Then, a single sub-roller 13 having a wide width is directly installed and fixed to the other support shaft 12.

On the side of the slider 5 opposite to the main roller 6, that is, on the side of the gate body 2, a cylindrical pipe-shaped spring receiving portion 8 integrated with the slider 5 is widely provided, and the center shaft support shaft 4 is also rotatable. There is. In the spring receiving portion 8,
A torsion spring 15 is wound and installed, and the torsion spring locks the locking portion 16 on the upper end of the slider 5, while extending on the other support shaft 12 side and engraved on this. It is elastically fitted and fixed to the stop groove 14 from below, and by this torsion spring 15, when the gate body 2 is vertically moved up and down between the pair of support shafts 4 and 12, the other With respect to the support shaft 12, this is always urged to accumulate upward.

In the figure, 11 is a balancer installed especially in this example,
The balancer 11 is supported by an upper rotating holder (not shown) by a wire 10 whose one end is hooked on a hook 9 which is fixed upright on the upper surface of the slider 5 to reduce the load when the gate main body 2 is moved up and down.

On the other hand, the pair of vertical columns 17, 17 are long ones having a height of about 2.2 m from the surface of the earth, and each column is hollow and the column body 18 for receiving and storing the balancer 11 is separately manufactured. It is provided with two guide rails 19 and 23 which are vertically installed so as to be parallel and integrated by being attached.

The rear (inner) guide rail 19 for the main roller, out of the two threads, is provided with opposing ridges 20, 20 that engage with the outer peripheral groove 7 provided on the main roller 6 in the front-rear direction. A slider guide 21 is provided on the side of the gate body 2 for tightly fitting the slider 5 and restricting the slider 5 from rotating, and the guide rail 19 allows the main roller 6 and the slider 5 to be guided up and down at the same time. At the upper end position of the guide rail 19, a roller stopper 22 that is in contact with the main roller 6 and restricts its rise is fixedly installed.

On the other hand, the guide rail 23 for the sub-roller is configured to have a vertical portion 24 and a jumping guide portion 25, both of which are grooves, and the vertical portion 24 is below the height of the column 17. Between the two-thirds, it is provided in parallel with and adjacent to the main roller guide rail 19. And, on the other hand, in about 1/3 above the rest of the height,
A front and rear flip-up guide portion 25 is provided so as to be continuous with the upper end of the vertical portion 24.

At this time, the flip-up guide part 25 is centered on the position of the center shaft support shaft 4 at the top dead center of the main roller side with the main roller 6 being in contact with the roller stopper 22 and the gate main body 2 being at the highest position. , Along a circular arc locus whose radius is the distance between the pair of support shafts 4 and 12, and the length of the arc is about 200 ° about the support shaft 4. The jump guide portion 25 continuously receives the sub-rollers 13 that have risen in the vertical portion 24, and the other support shaft.
The reference numeral 12 makes it possible to ascend or descend with respect to the support shaft 4 of the center shaft so as to define a rotation locus.

In this example described above, as is already known, the gate body 2 is always a roller-equipped two-sided shaft for the main roller between the lower vertical fixed position and the upper horizontal position of the pair of vertical columns 17, 17.
The guide rails 19 and 23 for the sub-rollers make it possible to move up and down, and when the gate body 2 is manually pushed upward for opening, the sub-roller 13 enters the flip-up guide portion 25 at its highest position, The accumulated urging spring 15 acts to rotate the urging spring 15 to a horizontal position and holds the urging force of the urging spring 15 in a substantially consumed state, while the closing is By applying a pulling down force to the gate main body 2 (when the position is high, a pulling portion such as a chain can be provided), the operation is reversed to return to the fixed position.
Is rotated with respect to the support shaft 4, so that the urging force is accumulated and applied to the urging spring 15.

By the way, in the above-mentioned embodiment, in order to ensure the stable raising and lowering of the gate main body, the slider is used and two main rollers are attached to this, but it is possible not to interpose such a slider. For example, the main gate body is rotatably fixed to one of the support shafts, and as a result, a spring is provided on the support shaft that does not rotate itself and a single main roller is directly rotatably mounted on the support shaft. Then, the same operation as described above can be achieved.

Also, including the case where this slider is not used, if the locking part on one end side of the torsion spring is received by a spring stopper provided appropriately in the guide rail, the gate body will still be between the pair of support shafts. It is possible to accumulate the biasing force when the rises.

The positional relationship between the pair of support shafts does not need to be near the central position of the gate main body as long as the support shaft for the main roller is required to be horizontal or above the support shaft on the sub roller side. , By changing this, it is possible to open and open the gate main body to the front and rear side with respect to the vertical column.

The flip-up guide part is used for the sub-roller forced rotation along the arc locus centered on the support shaft position at the top dead center on the main roller side, and for the curving up and down in the front-back direction,
The position where the main roller does not rise is determined at the position above the support, but it is effective to set it as high as possible to prevent danger.

On the other hand, not only the gate body but also the panel body can be designed appropriately, and there is no obstacle in opening and closing operation even if it is bulged in the front and back, in this case, the gate body at the time of closing. The trajectory is higher in the middle part, so the danger avoidance upper part is good.

Although the balancer is not indispensable, it is desirable to install it as much as possible in order to assist the lifting and lowering of the gate main body, including providing it on one side of the gate main body. On the other hand, for example, by further fixing the wire to the support shaft for the main roller, winding the wire on the winding device provided on the upper frame, and rewinding the wire, the opening and closing of the gate main body can be electrically operated. Further, as a lifting assisting means instead of the balancer, it is also possible to apply a pulling force to the wire by an upper coil spring.

The urging spring is not limited to a torsion spring, but a leaf spring or the like can be appropriately processed and used, but by adjusting the urging force of this spring, the gate main body can be opened horizontally or inclined to open. However, it is desirable to make it as horizontal as possible in terms of appearance. Of course, for leveling, it is possible to provide a stopper at the horizontal position on the side of the flip-up guide part, and it is also possible to install a lock device on the main body of the gate that jumps up to prevent flapping in strong winds. it can.

In the present invention, the column height is preferably about 1.9 m to 2.4 m, and the gate main body is appropriately sized as a partition body.

As described above, the present invention is applied to each specific material, structure, shape, dimension,
The addition of other members and the like may be appropriately modified and carried out without departing from the spirit of the invention.

[Advantages of the Invention] As described above, according to the present invention, biasing springs are respectively provided between a pair of support shafts projecting close to the intermediate positions on both sides in the longitudinal direction, and one of the support shafts has a direct or slider. Main gate for vertical lifting via the main shaft and vertical sub-roller on the other support shaft, and a single gate main body with two rollers on one side; guide rails for main roller and sub-roller And the vertical direction of the sub-roller guide rail is continuous with this and is used for the sub-roller forcible rotation following the circular arc centered on the main roller side top dead center spindle position. Since it is characterized by comprising a pair of vertical stanchions provided with a forward and backward curving up guide part, it has a gate main body whose downward position is a fixed position between the pair of vertical stanchions when it is closed, and when it is opened. This gate It is possible to obtain a flip-up type lifting gate that rotates the main body above the supporting column and jumps up to open it horizontally (or in an inclined shape) and holds this open state. Therefore, in the closed state of the gate main body, the gate main body is arranged on the same plane as the pair of opposed vertical columns or within a slight protrusion width, and the jumping at the time of opening is not performed at a fixed position of the gate main body. Therefore, the installation space as a gate is small, the rear flower beds and the like are not an obstacle to the installation, and there is no dead space near the gate.

Further, since the flip-up is performed above the pair of vertical columns, it is possible to reduce the risk of the gate main body colliding with a child, a vehicle or the like when rotating.

In addition, since the gate body is equipped with two shafts with one side with rollers, it can be lifted and lowered in a stable and reliable manner, and one of them will enter the flip-up guide part as a sub roller, so the structure is extremely simple. You can do it.

In addition, since the biasing spring is provided between the pair of support shafts, this contributes to the jumping up, and the gate main body that is jumped up horizontally (or in an inclined shape) can be held as it is.
