Abstract

(57) [Summary] [Purpose] To provide a corner guard that absorbs impact force applied to the corners of a wall surface or a pillar, and that is excellent in preventing damage to the corners. A roller support frame 2 is attached to a vertically long notch 1 provided in a wall or a corner of a pillar, and a roller 3 having a cushioning property is rotatably attached to the roller support frame 2. The roller 3 is rotatably supported so that a part of the peripheral surface of the roller 3 protrudes slightly from the front surface of the wall surface or the vertical surface of the column.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corner guard which is attached to a corner of a wall or a pillar in a room in a building such as a hospital, a nursing home, or other public facilities to protect the wall or the pillar from being damaged by an impact of a trolley or the like. is there.

[0002]

[Prior art]

 Japanese Utility Model Publication No. 3-30487 is known as a corner guard that is attached to the corners of walls and pillars in hospitals, nursing homes, and various public facilities to protect the corners of walls and pillars from the impact of a dolly. .

[0003]

[Problems to be solved by the device]

 The one disclosed in Japanese Utility Model Publication No. 3-30487 is composed of a cushion material protruding from an L-shaped substrate fixed to a corner portion of a wall surface and a cover body made of a hard synthetic resin covering the front surface of the substrate. However, since the impact force applied to the cover due to the collision of the trolley is absorbed by the deformation of the cushion material and the cover body, there is a problem that the absorbency of the impact force is insufficient.

[0004]

[Means for solving problems]

 According to the present invention, the impact force applied from the outside is diverted by the rotational force of the roller to weaken the impact force, and at the same time, the elasticity of the roller absorbs and absorbs the impact. A roller supporting frame fixed in a vertically long notch formed in the upper part makes a roller having a cushioning property rotatable and a part of the peripheral surface of the roller is slightly smaller than a wall surface or a vertical surface of a pillar. It is pivotally supported so that it protrudes to the front.

【Example】

 The corner guard of the present invention is rotatably mounted in the vertical direction at the corners of a wall surface or a pillar body. Fig. 2 is mounted on the wall surface and Fig. 4 is mounted on each corner portion of a concrete pillar body. Therefore, a hook-shaped cutout portion 1 having a predetermined length is formed in a vertical direction at a corner portion of a wall surface or a pillar body, a roller support frame 2 is attached to the cutout portion 1, and the roller 3 is attached to the roller support frame 2. Is rotatably supported and a part of the peripheral surface of the roller 3 is pivotally supported in a state of protruding slightly to the front surface from the vertical surface of the wall surface or column.

As shown in FIG. 3, the roller 3 is composed of a core material 4 made of metal such as aluminum or an iron pipe, and an elastic material 5 such as a hard or semi-hard synthetic resin coated on the outer peripheral surface of the core material 4. ing.

Bearings 6, 6 at the upper and lower ends of the roller 3 are rotatably fitted to shafts 7, 7 protruding from the roller support frame 2.

As means for rotatably attaching the roller 3 to the roller support frame 2, although not shown in the figure, shafts are provided at the upper and lower ends of the roller 3 so that the roller support frame 2 is provided with bearings. Can also be implemented.

Further, although FIG. 1 shows an example in which one roller is fixed as the roller 3 from near the floor surface to near the ceiling surface, a plurality of rollers having a predetermined length are partially attached. It goes without saying that it is good.

[0010]

[Effect of device]

 In the corner guard of the present invention, the roller 3 having cushioning property is rotatably attached to the wall or the corner portion of the pillar, so that when the roller is impacted, the roller 3 rotates and its impact force is increased. It has the effect of diverting and weakening a part of.

As described above, the roller weakens the impact force by diverting a part of the impact force by the rotation as described above, and at the same time, since it has cushioning properties, it also has an effect of elastically absorbing and absorbing the impact from the outside. As a result, both effects are combined to exert excellent effects in preventing damage to wall surfaces and pillar surfaces and protecting pedestrians from impact.
