Abstract

PURPOSE:To effectively absorb impact at the colliding time in a guard rail for a building. CONSTITUTION:The coping 3 of a guard rail for a building is formed of soft coating material 7 provided with contact pieces 8 to come in contact with the wall surface 1, and base material 6 for holding the coating material 7, provided with locking hooks 5 elastically locked to the locking claws 4 of a coping receiver 2. The coping 3 is fitted to the want surface 1 by supporting the upper and rover edge contact pieces 8 on the wall surface 1. When impact load is applied to the coping 3 in this state, the base material 6 absorbs impact force being deformed in the state of the center part being recessed. At the same time, each contact piece 8 receives shearing direction force by the flexural deformation of the base material 6, so that the wall part holding a recessed groove 9 is bendingly deformed. In addition, the locking hooks 9 move in the direction of being separated from the locking claws 4.. With this constitution of generating flexural deformation to the contact pieces 8 to follow the deformation of the base material 6, the facility of deforming the whole coping 3 is improved, and the locking hooks 5 at the deforming time is moved in the direction of being separated from the locking claws 4 so as to prevent the rupture of the locking hooks 5 and the generation of sliding resistance at the deforming time of the coping 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building guardrail.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional example of a building guardrail installed in a corridor wall surface 1 of various buildings or inside an elevator.

In this conventional example, the building guardrail is formed by fitting a metal bush 2 which is fixed to a wall surface 1 by an anchor member 10 and a bush 3 made of a metal material or a hard synthetic resin material. It is formed.

The above-mentioned head board 3 has an engaging hook 5 on its back surface, and is elastically engaged with an engaging claw 4 provided on the head board receiver 2 to be mounted. In addition, between the Kasagi 3 and the Kasagi receiver 2,
A cushioning space 11 is provided, and by bending the headstock 3 in the direction of the cushioning space 11, a shock is absorbed when a pedestrian, a stretcher bed, or the like collides with the building guardrail.

[0005]

However, in the above-mentioned conventional example, the headboard 3 is made of a hard material and does not exhibit the shock absorbing ability until a predetermined bending occurs, and the headboard 3 is
When an impact force is applied to the central portion, the retaining hooks 5 on the side of the headstock 3 follow the bending of the body of the headstock 3 and move outward as indicated by the arrows in FIG. Since it comes into pressure contact with the locking claws 4, the sliding resistance generated between the two becomes large, and relative movement at the sliding contact portion becomes difficult, and the umbrella tree 3 cannot exhibit the desired elasticity. Alternatively, it has a defect that the locking hook 5 is damaged or permanently deformed.

The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a building guardrail capable of effectively absorbing the impact at the time of a collision.

[0007]

According to the present invention, as described above, the above object is attached to a head support 2 fixed to a wall surface 1 and a surface portion of the head support 2 as shown in FIG. 1 corresponding to an embodiment. And a retaining hook 5 that elastically engages with retaining claws 4 provided on the upper and lower end surfaces of the retaining bracket receiver 2.
And a soft covering material 7 mounted on the surface of the base material 6. The covering material 7 is provided with an abutting strip 8 that abuts against the wall surface 1, and the corresponding abutting strip 8 is provided. On the contact surface of the wall surface 1 with the wall surface 1, a recessed groove 9 is provided through the central portion in the longitudinal direction, and the two locking claws 4 and 4 provided on the housing 2 are arranged so as to face each other. Achieved by providing a building guardrail.

[0008]

The capsule 3 of the building guardrail has a soft covering material 7 having an abutment strip 8 that abuts against the wall surface 1, and a soft covering material 7 for holding the covering material 7 and elastically engaging the locking claws 4 of the covering board receiver 2. A base material 6 having a locking hook 5 for stopping, and upper and lower edge contact strips 8
Is attached to the wall 1.

When an impact load is applied to the headstock 3 in this state, the base material 6 is deformed so that the center portion is dented and absorbs the impact force, and at the same time, the base material 6 is bent and deformed to abut the contact strips 8.
Receives a force in the shearing direction, the fleshy portion sandwiching the groove 9 is bent and deformed, and the locking hook 5 moves in a direction away from the locking claw 4.

The structure in which the contact strip 8 is bent and deformed so as to follow the deformation of the base material 6 improves the easiness of deformation of the entire head tree 3, and the locking hook 5 moves when deformed. By setting the direction away from the locking claw 4, breakage of the locking hook 5 and occurrence of sliding resistance when the cap 3 is deformed are prevented.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. The building guardrail is shown in Figure 1.
As shown in FIG. 2, it is composed of a headstock receiver 2 fixed to the wall surface 1 and a headstock 3.

The head cover 2 is a long material formed by extruding an aluminum material, for example, and is fixed to the wall surface 1 by an anchor member 10. Also, this Kasagi receiver 2
On the upper and lower edge surface portions, a locking ridge 12 is provided so as to extend longitudinally, and a locking claw 4 is provided at the tip of the locking ridge 12.

The locking claw 4 is, as will be described later, a head tree 3
The locking hooks 5 are provided at the side edges of the upper and lower two locking strips 12, 12 so as to face each other.

On the other hand, the headboard 3 is composed of a base material 6 and a covering material 7. The substrate 6 is an extruded aluminum material,
Alternatively, it is formed of a hard synthetic resin material, and locking bending portions 13 that are bent substantially perpendicular to the wall surface 1 are formed at the upper and lower edges.

On the back surface of the base material 6, a locking leg 14 having a locking hook 5 at its tip is provided in a protruding manner. The locking leg 14
Two rows are provided corresponding to the locking strips 12 of the headstock receiver 2, and the locking hooks 5 can be elastically locked to the locking claws 4 of the headboard support 2 arranged opposite to each other. It is arranged so as to face each other.

The covering material 7 is formed of a soft synthetic resin material in order to impart flexibility to the headstock 3 itself and improve the cushioning effect, and the upper and lower edges thereof are in contact with the wall 1 to bend. Equipped with Articles 8 and 8.

The contact strip 8 is formed thicker than the general cross section, and the fitting groove 15 is formed in the end face on the base material 6 side, and the groove 9 is formed in the end face on the wall surface 1 side through the length. It is recessed. Also,
The outer surface of the contact strip 8 has a gentle arcuate surface to prevent dust accumulation.

With the above construction, when installing the building guardrail, the headstock 3 is supplied in a state where the base material 6 and the covering material 7 are sub-assembled in advance, and first, after the headboard support 2 is fixed to the wall surface 1, Retain the hook 5 of the base material 6 to the head 2
The umbrella tree 3 is attached by elastically locking the locking claws 4 of.

When the headstock 3 is attached to the headstock receiver 2 as described above, a buffer space 11 is formed between the front surface and the wall surface 1 of the headstock receiver 2 and the back surface of the headstock 3, and the covering material is provided. The contact strip 8 of 7 is pressed against the wall surface 1.

FIG. 2 shows the shock absorbing action of the building guardrail according to the present invention. In FIG. 2 (a), the state when no load is applied is shown in FIG. 2 (b) when a load is applied. The deformed state of the part is shown.

First, assuming a case where an impact load is applied to the central portion of the headstock 3, the impact load is determined by the covering material 7 of the headstock 3.
Is partially absorbed by the elasticity of, and then the entire head tree 3 is elastically deformed.

As shown in FIG. 2 (b), the center of the headstock 3 which is in the state of two-point support by contacting the contact strip 8 with the wall surface 1 moves to the wall surface 1 side with the contact strip 8 as a fulcrum. As a result, the abutment strip 8 has a frictional resistance with the wall surface 1 due to a compressive load generated between the abutment strip 8 and the wall surface 1, and a force of the locking bent portion 13 to open the recessed groove 9. A bending moment is generated in the left and right meat parts.

As a result, each fleshy portion of the contact strip 8 absorbs the impact force while being deformed in a bending manner from the base end portion by a small load as compared with the case of being deformed only by the compressive load.

Further, at the same time when the central portion of the base material 6 is deformed, the locking hooks 5 of the base material 6 move toward the edge side, that is, in the direction away from the locking ridges 12 of the headstock receiver 2, and the locking ridges are moved. Interference with 12 is prevented, and breakage of the locking leg 14 due to the interference and generation of sliding resistance against deformation of the headstock 3 are prevented.

In the above description, the case where an impact load is applied to the central portion of the headstock 3 has been described, but even when an impact load is applied to the end portion, the headstock 3 in the two-point support state is Shows similar behavior.

[0026]

As is apparent from the above description, according to the building guardrail of the present invention, the covering material of the headstock is
Since a contact strip that abuts the wall surface is provided and a concave groove is provided in the end surface of the contact strip on the wall surface side, the bending moment applied to the contact strip can be effectively used due to the deformation of the headstock due to impact load. The contact strip can be deformed.

As a result, the contact strip is easily deformed as compared with the case where it is deformed only by the compressive load,
The deformability of the entire headstock is improved, and the impact absorption capacity can also be improved.

Further, since the retaining hooks on the side of the headstock are locked from the direction away from the locking claws on the side of the headstock when the headstock is deformed, mutual interference at the time of deformation is prevented,
It is possible to prevent permanent deformation or breakage of the locking hooks due to interference, and it is possible to prevent the bushes from being easily deformed due to mutual sliding contact resistance and to reduce the shock absorbing ability.
