JPH08284399A - Shock absorber and gondola for works - Google Patents

Abstract

PURPOSE: To efficiently absorb shocks and prevent damage of a window glass or the like, by fitting a shock-absorbing bar material made of rubber or the like to the external wall face of a working gondola at both ends thereof so as to form half-arcuate shape. CONSTITUTION: A bar-shaped or pipe-shaped shock absorbing body 8 is provided, which has a flexible material like rubber or plastics and a D-shaped section and both flat ends. Both ends of the shock absorbing body 8 are fitted to the external wall face 6a of a working gondola 6 with a fitting plate 9 of fitting tools 12, 12 and an angle-shaped fitting plate 9a. In this time, the shock absorbing body 8 is bent so as to position the flat face 8a in the inside and form a half-arcuate shape. As a result, even when the gondola body 6 swings and collides with the external wall or the window glass or a building, the shocks are efficiently absorbed by the shock absorbing body 7 to prevent the external wall or the like from damage.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorber attached to a place that absorbs a shock and a work gondola having the shock absorber.

[0002]

2. Description of the Related Art As a shock absorber attached to a conventional work gondola or the like, a block made of a rubber material is used.

[0003]

The conventional shock absorber formed of a rubber material in the form of a block has the drawbacks that if the shock absorbing portion is made to project to the outside, the shock absorber becomes large and heavy and unsightly. .

In view of the above-mentioned conventional drawbacks, the present invention has been made.
It is possible to take a large protruding dimension and is lightweight,
An object of the present invention is to provide a work gondola capable of reliably preventing damage to a shock absorber and a window glass capable of sufficiently absorbing shock.

The above and other objects and novel characteristics of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

[0006]

In order to achieve the above object, the present invention provides a rod-like impact having a D-shaped cross section and flat end portions made of a bendable material such as a rubber material and a synthetic resin material. An absorber main body, and a fixture capable of attaching the impact absorber main body attached to both ends of the impact absorber main body to the impact absorber with a flat surface having a semicircular shape located inside. Constitutes a shock absorber.

Further, the present invention is a work gondola main body on which a worker carrying a cleaning work such as a window glass suspended vertically by a rope from a rooftop of a building or the like rides, and an outside of the work gondola main body. A work gondola comprising a shock absorber for preventing damage to a window glass or the like attached to a wall surface, wherein the shock absorber is made of a bendable material such as rubber or synthetic resin and has a D-shaped cross section with both ends. The pipe-shaped shock absorber body formed flat and the work gondola so that the shock absorber bodies attached to both ends of the shock absorber body have a semi-circular shape with a flat surface located inside. A work gondola is constructed by using a fixture that can be attached to the outer wall surface of the main body.

[0008]

The shock absorber having the above-described structure is attached to the shock absorber main body, which is formed in the shape of a D-shaped rod, by bending it into a semi-circular arc so that the flat surface is located inside. The shock absorber body is in a state in which a compressive stress and a tensile stress are applied, and it is possible to give rigidity,
Even if it largely projects outward, it is possible to sufficiently absorb the shock.

[0009]

It is composed of 7, 7, and 7.

The shock absorbers 7, 7, 7, 7, 7, 7 are made of a bendable material such as a rubber material or a synthetic resin material. As shown in FIG. The formed pipe-shaped shock absorber body 8 and the shock absorber body 8
Angled mounting plate 9, plate-shaped mounting plate 9 on both ends of
a and plate-shaped mounting plate 9a and angle-shaped mounting plate 9
A plurality of screws 10 sandwiching the end of the shock absorber body 8 between
It is possible to bend the shock absorber main body 8 attached in step 1 so that it has a semi-circular shape with the flat surface 8a located inside and attach it to the outer wall surface 6a of the work gondola main body 6 with a plurality of screws 11. It is composed of fittings 12, 12.

A working gondola 1 constructed as described above.
The work gondola body 6 moves up and down by extending and retracting the pair of ropes 4 and 4 by the electric winches 5 and 5. If the work gondola body 6 sways in the front-back direction when the work gondola body 6 is moved up and down or when cleaning the window glass or the like, the shock absorbers 7, 7, 7, 7, 7, 7
Collide with the window glass and the outer wall surface of the building 2 to prevent damage to the window glass and the outer wall surface.

When the shock absorber 7 collides with a window glass or the like, the elastic force of the shock absorber body 8 itself, the deformation of the shock absorber body 8 in the shape of a semi-circular arc, and the shock absorber body. Since the flat surface 8a of 8 is bent so as to be located inward, rigidity that prevents lateral deformation is obtained, and optimum shock absorption that does not damage the window glass or the like can be performed.
