Definitions

  • the lever element designed as a bending element
  • the roller guide shoe is evidently characterized by a particularly simple design, as it essentially consists of only three components: the support structure, the lever element, and the roller.
  • the support structure can be made of a high-strength plastic material, e.g., PE, PP, PA, PS, PES, POM, PEEK, or TPEs, whereby fibers can also be added to the plastic material to reinforce the structure. It is particularly preferred to manufacture the support structure from a fiber-reinforced plastic.
  • a high-strength plastic material e.g., PE, PP, PA, PS, PES, POM, PEEK, or TPEs
  • At least one roller can have an internal bearing bushing and an outer wheel rim, freely rotatable to the bearing bushing via, for example, a roller bearing or a plain bearing, to form the running body.
  • the bearing bushing and the wheel rim can be made of plastics.
  • the wheel rim can, for example, be made of several plastic components, which can further improve ride comfort.
  • a locking element preferably designed as a projection
  • the projection It is integrally formed with the support structure and can be easily created using the aforementioned injection molding process.
  • separate locking elements could also be used, which could be detachably or permanently attached to the support structure.
  • the locking element is a detent lug in which the lever arm engages with the detent lug in a detent-like manner.
  • the detent lug can include a contact surface that makes contact with the lever element when the detent is engaged, and a ramp-like approach surface adjoining the contact surface. This ramp-like approach surface can be inclined such that, during assembly, the lever element can move along the approach surface until the end position, or until the detent is engaged, is reached; the lever arm is then in contact with the contact surface, which ultimately provides the support.
  • the lever element can have two lever arms that define a V-shape.
  • a V-shaped lever element is particularly well-suited as a bending component for applying preload to the roller. Thanks to the V-shape, the two rigidly connected lever arms easily provide spring-like properties, enabling the bending required to generate the preload.
  • the V-shape is especially advantageous when the lever element is made of plastic.
  • the lever element may then preferably have reinforcing ribs or webs extending transversely and preferably provided on a lateral outer contour for stiffening.
  • the lever element can have a stub axle integrally formed laterally at the free end of the lever arm to accommodate the roller.
  • the roller can be inserted into the stub axle via the bearing bushing. be used.
  • the roller guide shoe can have three rollers. These three rollers can consist of two rollers facing each other, which serve to guide along the parallel lateral guide surfaces of the guide rail, and one roller which serves to guide along the end-face guide surface of the guide rail that connects the lateral guide surfaces. Each roller is preferably associated with a lever element.
  • the support structure for the roller guide shoe with three rollers can have a preferably plate-like base section and three preferably perpendicular web sections projecting from the base section.
  • the web sections can form a "T" shape in a top view.
  • roller guide shoe has three rollers
  • at least two of the three lever elements, and in particular the lever elements with the rollers that serve to guide the rollers along the lateral guide surfaces of the guide rail each have two coaxial axle stubs for receiving rollers arranged on opposite sides of the lever element.
  • This allows identical lever elements to be used for the two lever elements intended for lateral guidance.
  • This has the advantage that the same mold can be used for injection molding, which has a positive effect on manufacturing costs.
  • the support structure preferably has web sections projecting at right angles from the base section to support the rollers, with the web sections being connected to each other via a connecting area.
  • An emergency guide can be integrated into the support structure such that an emergency guide channel extending along the web sections is provided in the connecting area. Due to its length, such an emergency guide channel is characterized by excellent emergency guidance properties.
  • the length of the emergency guide channel can essentially correspond to the outer dimension of the support structure with respect to the longitudinal direction.
  • the emergency guidance channel can be formed by channel wall sections, which form a U-shape.
  • the channel wall sections together form a U-shaped profile section.
  • This U-shaped profile section is preferably an integral part of the support structure and monolithically connected to it.
  • the web sections can connect to the channel wall sections at right angles. Consequently, each web section is associated with a channel wall section, and the respective web sections terminate in their corresponding channel wall sections.
  • a further advantage of this design of the emergency guidance channel is that it can provide additional stiffening to the support structure.
  • Another aspect of the invention may relate to an elevator car or a counterweight for an elevator, wherein the elevator car or the counterweight is equipped with the roller guide shoes described above.
  • another aspect of the invention may relate to an elevator system comprising an elevator car and a counterweight connected to the elevator car via support means and movable in the opposite direction to the elevator car, wherein the elevator car or the counterweight is equipped with such roller guide shoes for guiding the elevator car or the counterweight on guide rails.
  • FIG. 1 shows a roller guide shoe for an elevator, designated as 1.
  • the roller guide shoe 1 is used to guide an elevator car or a counterweight of the elevator along a guide rail extending in the longitudinal direction z (not shown here).
  • An elevator for a multi-story building may have an elevator shaft in which an elevator car is transported.
  • a lift is a vertical elevator capable of moving people or goods up and down between floors. For example, it can be designed as a traction lift system with a counterweight that moves in the opposite direction to the lift car, with the load-bearing elements typically being cables or belts.
  • the roller guide shoe 1 shown is particularly suitable for guidance along a guide rail formed by a T-profile (see below).
  • Fig. 2 The T-profile can, for example, be a steel profile manufactured by rolling.
  • Such guide rails 2 have been known, used, and widely distributed for a long time.
  • the roller guide shoe 1 has three rollers 4, 4', 5. Each of the rollers 4, 4', 5 is in contact with a guide surface of the guide rail 2 and runs along it during cabin travel.
  • the roller guide shoe 1 further comprises a support structure 6 with a plate-like base section 7 and web sections 8, 9 projecting from the base section 7.
  • the base section 7 serves to attach the roller guide shoe 1 to the elevator car or to the counterweight.
  • Holes 27 are provided in the base section 7 for attaching the roller guide shoe 1 (see figure).

  • Metal sleeves (not shown) can be inserted into the holes 27 for reinforcement.
  • the web sections 8 and 9 serve to support and carry the rollers 4, 4', and 5.
  • Web section 8 serves to carry the two rollers 4 and 4' facing each other.
  • Roller 5, which guides along the end face of the guide rail 2 is associated with web section 9.
  • Lever elements 10, 11 are arranged between the support structure 6 and the respective rollers 4, 4', 5. Each roller 4, 4', 5 is freely rotatable at a free end of the respective lever element 10, 11.

  • the lever element 10, 11 is inserted into a pivot cam 16, which is arranged laterally on a bridge section 8, 9. After insertion, the joint cam 16 engages in the recess 17 on the lever element 10, 11.
  • the lever element 10, 11 is designed as a bent component, which allows a preload to be applied to the roller 4, 4', 5, at least in the operational state.
  • the lever element 10, 11 is positioned in the roller guide shoe 1 such that it is bent, thereby creating a preload that presses the roller 4, 4', 5 against the guide rail 2.
  • This bending is minimal and barely perceptible to the naked eye. Thanks to its spring-like properties, which are primarily influenced by the effective length of the lever arm, its shape, and the choice of material, the desired contact pressure for the rollers can be set quite precisely.
  • the lever element 10, 11, and in particular the lever arm 12 associated with the roller is elastically deformed in the process.
  • the roller guide shoe 1 can be designed such that the bending necessary to effect the preload is applied as far above the joint axis as possible, i.e. in the lever arm 12 between the joint axis and the roller, in order to avoid causing wear by rotation in the joint cam 16.
  • roller guide shoe 1 achieves sufficiently good ride comfort without additional spring elements such as coil springs or elastomer-based springs.
  • additional spring elements such as coil springs or elastomer-based springs.
  • a further advantage is that such bent parts can be manufactured inexpensively in large quantities.
  • the lever element 10, 11, designed as a bent part has a V-shaped configuration.
  • the two lever arms 12, 13 define a V-shape.
  • the lever arms 12, 13 enclose an angle of 120° to 150°.
  • the "V" is therefore obtuse-angled.
  • other shapes for the lever elements 10, 11 would also be conceivable.
  • the lever element 10, 11 could have a curved shape or another shape with one or possibly several curves.
  • Each of the lever elements 10, 11 has transverse and lateral Reinforcing ribs 21 are provided along the outer contour for stiffening. Depending on their number, orientation, and shape, the reinforcing ribs 21 can also be used to optimally adjust the bending in the lever element for generating the preload.
  • the respective web sections 8, 9 of the support structure 6 have locking elements 18 as abutments for the respective lever elements 10, 11.
  • the locking element 18 is designed as a projection formed laterally on the support structure 6 and forms a stop to prevent pivoting of the lever elements 10, 11 about the pivot axis.
  • the locking element 18 is exemplified as a detent lug in which the lower lever arm 13 of the lever elements 10, 11 engages with the detent lug.
  • the support structure 6 has web sections 8, 9 projecting at right angles from the plate-like base section 7 for carrying the rollers 4, 4', 5.
  • the web sections 8, 9 clearly form a T in plan view.
  • the T-shaped web sections 8, 9 projecting from the base section 7 are connected to each other via a connecting area, in which an emergency guide is integrated such that it forms an emergency guide channel 25 extending along the web sections 8, 9.
  • Channel wall sections 26 are provided to form the emergency guide channel 25, which together form a U-shaped profile section in plan view.
  • the respective web sections 8, 9 connect to the associated channel wall sections 26 at right angles.
  • a metallic insert (not shown here) can be provided to reinforce the emergency guide channel 25. This insert can be a U-shaped metal part in cross-section, which is inserted into the emergency guide channel and rests against the channel wall sections 26 after insertion.
  • the support structure 6 is designed as a one-piece molded body made of a plastic.
  • the support structure 6 is manufactured as an injection-molded part.
  • the support structure 6 can be made of a high-strength plastic material, e.g., PE, PP, PA, PS, PES, POM, PEEK, or TPEs, with the support structure 6 being particularly preferably made of a fiber-reinforced plastic.
  • a high-strength plastic material e.g., PE, PP, PA, PS, PES, POM, PEEK, or TPEs
  • the support structure 6 being particularly preferably made of a fiber-reinforced plastic.
  • other materials are also conceivable.
  • the support structure 6 could also be made of metallic materials, for example, an aluminum casting.
  • the lever elements 10, 11, like the support structure 6, are also one-piece molded plastic components. Numerous advantages arise, particularly when the lever elements 10, 11 are injection-molded plastic parts. Injection-molded parts can be manufactured with high precision and at low cost. Even relatively complex lever shapes can be easily produced in this way. The bending and preload for the roller 4, 4', 5 can be generated or adjusted via the geometry and material of the lever element 10, 11, for which injection-molded parts are particularly well-suited.
  • suitable materials include, for example, PE, PP, PA, PS, PES, POM, PEEK, and TPEs. Fiber-reinforced plastics, such as glass fiber-reinforced plastic, are particularly suitable.
  • roller guide shoe 1 consists of only a few components, making it easy to assemble and offering significant cost advantages.
  • the bent part or lever element 10, 11 of the roller guide shoe 1 essentially performs the combined function of a roller support and a spring element.
  • the spring constant of the lever element 10, 11 can be determined by its lever structure.
  • roller guide shoe 1 A metallic version of the roller guide shoe 1 would also be conceivable.
  • the support structure 6 could be made of metallic materials, for example as an aluminum casting.
  • the lever elements 10, 11 could also be made of aluminum, for example.
  • rollers 4, 4', 5 are identical in this case. However, it is also conceivable that different rollers 4, 4', 5 could be used. In particular, roller 5 could be designed differently from rollers 4 and 4'.
  • Each roller 4, 4', 5 comprises an inner bearing bushing 14 and an outer wheel rim 15, which is freely rotatable from the bearing bushing via a rolling bearing. Both the bearing bushing 14 and the wheel rim 15 are preferably made of plastics.
  • the wheel rim can consist of one plastic component or, optionally, of several plastic components made of different plastics.
  • the components can be constructed using multi-stage injection molding processes.
  • the wheel rim 15 can be designed as a 2K injection-molded part.
  • An outer component of the wheel rim 15 would typically have a greater hardness than the inner component.
  • the roller guide shoe 1 which can be removed, is constructed from only a few components. Essentially, the roller guide shoe 1 consists of only three components: the support structure 6, the lever elements 10, 11, and the rollers 4, 4', 5. The three lever elements 10, 11 are almost identical. The two lever elements 10 for the rollers 4, 4' are identical; the lever element 11 for the roller 5 differs from the lever elements 10 only in that, for space reasons, it has a stub axle 22 on only one side. In principle, however, this lever element 11 could also be designed like the lever elements 10 with two stub axles 22, 23 (e.g., in a roller guide shoe with rollers of a larger diameter).
  • FIG. 2 Figure 1 further shows how the locking lug is designed to form the locking element 18.
  • the locking lug has a contact surface 19 which contacts the lever element 10, 11 when the locking connection is established, thus defining a stop.
  • a ramp-like approach surface 20 adjoins the contact surface 19.
  • the approach surface 20 is inclined such that, when the lever element is assembled, the relevant lever arm 13 of the lever element 10, 11 can move along the approach surface of the locking lug until the end position is reached, in which the lever element 10, 11, or rather its lever arm, is engaged with the locking lug in a detent position.
  • the roller guide shoe 1 can be mounted as follows: First, the support structure 6 is attached to the elevator car or the counterweight, e.g., by means of screws 28. Then, the lever elements 10, 11, which are already fitted with the rollers 4, 4', 5, are mounted to the support structure 6. The rollers 4, 4', 5 can be pre-mounted or, if necessary, attached to the lever elements 10, 11 on site. To mount the lever elements 10, 11 to the support structure 6, they are placed on the support structure 6, snapped or slid onto the pivot cams 16 in the area of the pivot axis by axially inserting their recess 17, and then engaged at the locking element.
  • retaining rings but also nuts, cotter pins, etc., can be used, which are attached to the joint cam 16.
  • Locking devices could also be, for example, detent projections on the circumference of the joint cam 16, onto which the lever elements 10, 11 snap.
