Description

[Detailed description of the invention] This invention can be installed on walls and pillars such as stairs and hallways in buildings, especially hospitals and nursing homes, or around the waist inside elevators, and can be installed on walls and pillars, as well as transport equipment, etc. This invention relates to a guardrail for a building that prevents damage and can be used by pedestrians as a handrail or push hand.

In general, this type of guardrail is of the direct-mounted type, in which the back side of the guardrail is fixed directly to a fixed surface such as a wall, with the primary purpose of preventing damage caused by collisions with stretchers, transport equipment, etc. in hospitals, etc. , Similarly, in hospitals and nursing homes, etc., in order to prevent damage caused by collisions with stretchers and transport equipment as described above, and to also function as a handrail, a bracket is installed with a gap between the guardrail and the fixed surface. There are two types of fixed handrail types.
Depending on the installation location of the guardrail, one of the types was selected and installed, but since these two types have different fixing means, each type is made into a shape according to the fixing means, and the same guardrail can be used as described above. However, it could not be installed for both types, and it was extremely uneconomical in terms of production costs and inventory.

In addition, some conventional guardrails are constructed by fitting a cushion body made of soft synthetic resin or synthetic rubber into a long body made of extruded material such as aluminum alloy or bent material such as steel plate. However, it was not possible to obtain a sufficient cushioning effect, and the guardrail was deformed at the same time as the transport equipment etc. was damaged.

The present invention was developed to eliminate the drawbacks of conventional guardrails as described above.It is made of hard or semi-hard synthetic resin and has a flat plate-like main body with approximately even thickness that protrudes inward on both the upper and lower sides. A pair of protrusions are provided on the inner side of the vicinity of the tip of the rib at a distance from each other and project in the vertical direction in parallel with the flat main body. A pair of horizontal protrusions that are shorter than the ribs and have a hook-shaped portion at the tip are provided at a distance from each other in the central part, and brackets are secured to the upper and lower ends of the flat main body and to the back surface of the central part, respectively. By forming a locking groove, it can be used for both direct mounting type and handrail type.
To provide a building guardrail with excellent cushioning effect.

The structure of the present invention will be explained in detail based on the embodiments shown in the accompanying drawings. 1 is a guardrail made of hard or semi-hard synthetic resin, and is a flat plate extending in the vertical direction and having a substantially average thickness. Ribs 3 projecting inward on both upper and lower sides of the shaped main body 2
are formed integrally with each other, and a pair of projecting pieces 4, 4 are provided on the inner side of the vicinity of the tip of the rib 3, and are spaced apart from each other and project in the vertical direction in parallel with the flat main body 2. Projection piece 4,
A locking groove 5 is formed between the holes 4 and 4.

Further, at approximately the center of the back surface of the flat main body 2, a pair of horizontal protrusions 7, 7, which are shorter than the ribs 3 formed on both upper and lower sides of the flat main body 2 and have a hook-shaped portion 6 at the tip, are arranged at a distance. A locking groove 8 is formed between the horizontal protrusions 7, 7.

Of the ribs 3 provided on both the upper and lower sides of the flat main body 2, at least the ribs 3 located above have an appropriate width so as to provide a stable grip when used as a handrail.
Further, in order to improve the feel, it is desirable that the corners be formed in an arc shape.

When the guardrail 1 configured as described above is installed in direct contact with the wall surface 9 as a direct mounting type, the wing portion 10.10 having upward and downward elasticity as shown in the first country
The bracket 11, which is press-formed into a long shape from a steel plate or the like, is attached to a Fisher anchor or the like (
(not shown) is fixed to a wall surface 9, and then a locking groove is formed on the wing portion 10 above the brackets 1 to 11 fixed to the wall surface 9 on the inner side of the tip of the rib 3 above the guardrail 1. 5, and further press the lower part of the guardrail 1 against the brackets 1 to 11, and snap the locking groove 5 formed on the inner side of the tip of the lower rib 3 of the guardrail 1 into the lower wing part 10 of the bracket 11. It is fixed by mating with.

In addition, when the guardrail 1 is a handrail type that is attached by a bracket 11 at a distance from the wall surface 9,
As shown in the second figure, the head 14 of the adjuster 13 screwed into the stud 12 fixed to the wall surface 9 is inserted from the longitudinal end of the guardrail 1 to the approximate center of the back surface of the flat main body 2. The adjuster 13 fits into the formed locking groove 8.
The head 14 of the adjuster 13 is rotated to adjust the distance between the guardrail 1 and the wall surface 9, and then the clamp cover 15 is rotated in the direction of moving toward the guardrail 1.
The guardrail 1 is fixed by clamping and clamping the hook-shaped portion 6 on the back surface of the guardrail 1 by the clamp cover 15 and the clamp cover 15.

In addition, in the case of the direct attachment type shown in Figure 1, as shown in Figure 3, the locking groove 8 formed at the approximate center of the back surface of the flat main body 2 is made of flexible soft synthetic resin or the like. By filling the cushioning material 16 with the cushioning material 16 and bringing the tip of the cushioning material 16 into contact with the surface of the bracket 11, it is possible to prevent large deflection of the guardrail 1 due to excessive impact and prevent damage to the guardrail itself. This can be further improved.

The present invention has the above-mentioned configuration, and when the guardrail is fixed in direct contact with the wall surface, the locking grooves formed at the upper and lower ends of the flat main body, and between the guardrail and the wall surface. When using a handrail type that is fixed with a space between the two, it is attached to the wall by connecting it to the locking groove formed approximately in the center of the back of the flat main body via a bracket dedicated to these different types. This eliminates the need to manufacture two types of guardrails to match the different types of brackets and keep them in stock, which simplifies the production process and reduces inventory by half, resulting in significant cost reductions. can be achieved.

The guard rail is made of hard or semi-rigid synthetic resin, and includes a knob formed on the upper end of the flat main body, a pair of protrusions parallel to the flat main body provided inside the tip of this rib, and a knob formed on the upper end of the flat main body. The flat main body is reinforced by a horizontal protrusion placed approximately in the center of the back surface, which maintains appropriate rigidity and elasticity and prevents the guardrail itself from being damaged by horizontal loads caused by collisions with transport equipment, etc. At the same time, it is possible to prevent damage to the transport equipment, etc., and it is highly restorable, and can be used in the best condition for a long period of time without partial deformation due to frequent collisions.

Furthermore, the horizontal protrusion protruding from the center of the back surface of the flat main body is made shorter than the ribs protruding from both the upper and lower sides of the flat main body. Since a gap is maintained between the sideways protruding strips and the wall surface in the event of a collision, the horizontal protruding strips will not come into contact with the wall surface, and the cushioning effect will not be halved. Together with the ribs extending toward the bracket, a portion of the bracket is hidden, making it possible to create a clean appearance.
