Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a guide shoe that slides with a guide rail provided on a moving path and guides movement of a moving body such as an elevator ride.
[0002]
[Prior art]
Conventionally, a guide rail extending in the vertical direction is provided on the moving path (elevating path) of the elevator, and a guide shoe is provided on the riding rod, and the latter guide shoe is engaged with the former guide rail. By sliding and sliding, the elevator is guided up and down.
[0003]
As shown in FIG. 8, the guide shoe 51 holds a shoe 53 that slides on the guide rail 52, a vibration-proof rubber 54 that is bonded to the outer surface of the shoe 53, and the shoe 53 and the vibration-proof rubber 54. And a base 56 for fixing them to the riding rod 55.
[0004]
Conventionally, however, since the anti-vibration rubber 54 is directly bonded to the outer surface of the shoe 53 as described above, it is necessary to select a material capable of bonding rubber (for example, foamed polyurethane rubber) as the material of the shoe 53. Therefore, this causes the following inconvenience.
[0005]
That is, the material of the shoe 53 to which rubber can be bonded generally has a high coefficient of friction and requires oil lubrication. Therefore, a fueling device (not shown) is required, and since this fueling device takes up its own space, the overall space efficiency is not good. In addition, since the oil is scattered during operation, the maintenance environment is adversely affected. This is because more oil than necessary from the oil supply device is scattered around when the ride 55 is raised and lowered.
[0006]
[Problems to be solved by the invention]
In view of the above, the present invention can improve the efficiency of the guide shoe and the space around it, and at the same time, it is an oil-free structure that does not scatter oil and can improve the maintenance environment. The purpose is to provide.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a guide shoe according to claim 1 of the present invention is a guide shoe that slides with a guide rail provided on a moving path and guides movement of a moving body such as an elevator ride, It has an auxiliary material made of a material that can be bonded to rubber while being integrated with a shoe that slides with a guide rail, and an anti-vibration rubber is bonded to the auxiliary material, and the auxiliary material has a wall thickness of the shoe. In addition to being embedded in the surface, the surface is exposed at a window portion provided on the outer surface of the shoe, and the anti-vibration rubber is bonded to the surface exposed portion .
[0008]
[0009]
[0010]
In the guide shoe according to claim 1 of the present invention having the above-described configuration, an auxiliary material is integrated with the shoe, and the auxiliary material is made of a material (for example, metal or polyamide resin) capable of adhering rubber. Since the anti-vibration rubber is adhered to the shoe, it is not necessary to mold the shoe with a material capable of adhering rubber (for example, polyurethane foam rubber). Therefore, it is difficult to bond rubber as a material for the shoe, but it is possible to use a low sliding material (for example, polyethylene resin or polypropylene resin) having a small friction coefficient. A structure can be realized .
[0011]
In addition, in order to integrate the auxiliary material into the shoe , the auxiliary material is embedded in the thickness of the shoe, and the surface is exposed at the window provided on the outer surface of the shoe, and the anti-vibration rubber is adhered to the surface exposed portion. This is preferable because of high bonding strength.
[0012]
The guide shoe of the present invention having the above configuration is used in the field of elevators for lifting and lowering, and is also used in the field of structures having other sliding mechanisms.
[0013]
The present application includes the following technical matters.
[0014]
That is, in order to achieve the above object, one guide shoe proposed by the present application has the following contents.
(1) An adhesive material is interposed between the shoe and the damper rubber to achieve integration.
(2) A low-friction shoe material (for example, a difficult-to-adhere material such as polyethylene or polypropylene) is structurally hung on an auxiliary material (for example, an adhesive material such as metal or polyamide), and a damper rubber (for example, foamed material) is attached to the auxiliary material. It is characterized by baking (bonding molding) foamed rubber such as polyurethane rubber.
(3) The auxiliary material is mounted on a mold and integrally formed with the shoe.
(4) With this structure, not only difficult-to-adhere materials but also deformation of shoes unique to molding materials can be prevented, and the dimensions can be stabilized.
[0015]

And a right and left side surface portion 4b, and the cross section is formed in a substantially U-shape, and a groove-like slide for engaging and sliding on a guide rail (not shown) on the front surface thereof. A moving surface 9 is formed. Further, the shoe 4 is formed with the auxiliary material 3 embedded in the thickness of the shoe 4 by molding the shoe 4 with the auxiliary material 3 mounted in the product cavity space of a mold (not shown). The window portion 10 is further provided on the outer surface of the shoe 4, so that the auxiliary material 3 is partially exposed at the window portion 10. A plurality of window portions 10 are provided, and a cross-shaped holding portion 11 is provided between the window portions 10 to cover the auxiliary material 3 from the outside and enhance the holding effect. No window portion is provided on the inner surface (sliding surface 9) of the shoe 4.

As shown in FIG. 3, the anti-vibration rubber 5 is molded by foamed rubber such as foamed polyurethane rubber (foamed PUR) so that the cross section also has a substantially U-shape, and is disposed outside the shoe 4. A part is filled in the window portion 10 of the shoe 4 and baked and bonded to the exposed surface portion of the auxiliary material 3. Note that the window portion 10 of the shoe 4 is opened not only on the outer surface of the side surface portion 4b of the shoe 4 but also on the front end surface thereof, and also in the window portion 2 opened on the front end surface of the side surface portion 4b of the shoe 4. Since part 3 (a part of the front end surface of the side surface portion 3b of the auxiliary material 3) is exposed, the anti-vibration rubber 5 is baked and bonded to the auxiliary material 3 also in this part. The anti-vibration rubber 5 is not bonded to the shoe 4.
[0020]
As shown in FIG. 4, the base 6 is constituted by a combination of a case 7 and a lid 8 formed of a high-strength material such as glass-filled polyamide (PA) or aluminum so as to ensure a required strength. A recess-shaped storage and holding portion 12 for storing and holding the shoe assembly 2 made up of the auxiliary material 3, the shoe 4 and the vibration isolating rubber 5 is formed on the front surface of the housing. A flange-shaped receiving portion 13 is provided at the lower end portion of the receiving and holding portion 12 so that the received shoe assembly 2 does not fall down or be displaced.

That is, first, in the guide shoe 1 having the above-described configuration, the auxiliary material 3 is integrated with the shoe 4, and the auxiliary material 3 is made of a material capable of bonding rubber such as metal or polyamide, and foams with respect to the auxiliary material 3. Since the anti-vibration rubber 5 made of foamed rubber such as polyurethane rubber is bonded, the shoe 4 does not need to be molded from a material that can bond the rubber. Specifically, the shoe 4 is made of polyethylene or polypropylene. Molded with low friction material. Therefore, according to the shoe 4 made of a low friction material such as polyethylene or polypropylene, oil lubrication is unnecessary, the oil supply device can be omitted, and an oil-free structure can be realized. In addition, it is possible to improve the space efficiency in the vicinity thereof and to improve the maintenance environment without the oil scattering.
