Description

[Detailed explanation of the invention] This design has a square foot formed at the tip and a cylinder at the rear half, which is fitted into an engagement edge formed on the back side of the guardrail main body, from the inside of the cylinder. Secure with clamping screws,
Furthermore, the present invention relates to a guardrail mounting device in which the cylinder is loosely mounted in a bracket fixed to a wall surface and fixed by inserting a fixing screw from the outer peripheral surface of the bracket.

Conventionally, the lower part of various buildings and the inside of elevators, especially the walls of hospital corridors and the waist area inside elevators, have been exposed to the possibility of direct collision or scraping of movable sleeping cars, wheelchairs, transport vehicles, etc. with walls such as concrete. A guardrail covered with a cushioning material is installed to prevent damage to the wall surface, reduce the impact on patients, and serve as a guide rail for people with walking difficulties.This guardrail mounting device The stretcher has a mounting bracket with both upper and lower ends protruding to the front and a locking bent part that is attached to the wall, and an engaging protrusion on the back side to engage with the locking bent part of the stretcher. When one main body is pressed onto the mounting bracket, the locking bent portion of the mounting bracket and the engaging protrusion of the guardrail engage with each other to fix the guardrail main body,
This mounting device makes it easy to install the guardrail, but on the other hand, because the guardrail body is fixed only by the locking bent part of the mounting bracket and the engaging ridge of the guardrail, the impact applied to the guardrail is The engaging portions tend to loosen due to force, and once a guardrail has loosened, it is impossible to firmly fix it again, and there is a concern that the guardrail may come off after long-term use.

In this case, a square foot of a locking tool with a square foot at the tip and a cylindrical rear part is fitted into the fitting groove formed between the engagement edge and the pressing surface formed at the center of the back of the guardrail body. By inserting a locking screw from inside the cylinder and pressing its tip against the pressing surface, the engagement edge of the guardrail is clamped and fixed, and the second half of the cylinder is loosely attached to the bracket that is fixed to the wall surface to form a bracket. It is designed to be fixed by inserting a fixing screw from the outer circumferential surface of the cylindrical part, and the square foot of the locking tool fits into the fitting groove on the back of the guardrail to hold the guardrail, and the screw is inserted from the inside of the cylinder. The guardrail is firmly held by pressing the pressing surface with the locking screw inserted, and the cylinder at the rear half of this locking device is loosely attached to the bracket that is fixed to the wall surface at regular intervals and fixed with the fixing screw. Because of this, the guardrail can be easily installed, the mounting screws do not loosen even with the impact force applied to the guardrail after installation, and the guardrail is firmly held and can withstand long-term use.

To explain this with an example, the fitting that occurs between the suppressing surface 2 formed at the center of the back surface of the guardrail 1 and the hook-shaped engaging edges 3, 3' formed by bending oppositely from the upper and lower ends thereof. When continuously forming the square foot 5 at the tip and the cylinder 6 at the rear part in the groove 4, a sliding groove 7 is formed between the square foot 5 and the cylinder 6.
The square foot 5 of the locking tool 80 formed with the square foot 5 is fitted, and the set screw 9 is inserted from the inner center of the cylinder 6 toward the square foot 5 to close the square foot 5.
is clamped and fixed in the fitting groove 4, and the cylinder 6 of the fastening tool 8 is loosely fitted inside the oval bracket 11 having an inner peripheral surface 10 that is larger than the outer periphery of the cylinder 6. Insert the fixing screws 12 and 12' from the upper and lower outer peripheral surfaces to attach the clamping tool 8.
In the figure, 13 is a long hole for fixing the bracket, 14 is a hollow surface, 15 is a reinforcing screw plate, 1
6 is a cushioning material, 17 is a mounting bolt, and 18 is a wall surface.

The present invention has an inclined configuration, and the square foot 5 formed at the tip of the locking tool 8 is formed by the pressing surface 2 at the center of the back surface of the guardrail 1 and the engaging edges 3, 3'. This is because the engaging edges 3 and 3' are formed to have such a size and thickness that they can be fitted into the fitting groove 4, and the engaging edges 3 and 3' can also be fitted and slid into the sliding groove γ. By fitting the square foot 5 into the fitting groove 4, the locking tool 8 is firmly held, but it is also possible to prevent the locking tool 8 from moving laterally and to make it even stronger. In order to fix it in the fitting groove 4, a locking screw 9 is inserted from the center inside the cylinder 6, and its tip presses the pressing surface 2 to clamp and fix the engaging edges 3, 3'. .

In addition, the inner peripheral surface 10 of the oval bracket 11 is made slightly larger than the outer peripheral surface of the cylinder 6 so that the cylinder 6 can be easily attached loosely. After placing the bracket 11 at an appropriate position around the waist of the hallway wall 18, etc., and driving hole-in anchors through the long hole 13 for fixing the bracket, attach the bracket 11 to the wall 18 at regular intervals with mounting bolts, and then attach the bracket 11 to the wall 18 at regular intervals. Cut guardrail 1 to fit the length of
Fit the same number of locking tools 80 rectangular feet 5 as the brackets 11 into the fitting grooves 4 on the side end faces, and move each cylinder 6 to a position that matches the mounting location of the bracket 11. After fixing the stopper 8 to the back of the guardrail 1 by tightening the set screw 9 inserted into the center of the interior, lift the guardrail 1 and attach the cylinder 6 in the rear half of each stopper 8 to the inner peripheral surface of the bracket 11. The installation is completed by tightening the stators 12 and 12', which are loosely fitted into the bracket 10 and screwed into the upper and lower outer peripheral surfaces of the bracket 11. hold it in place, and tighten the locking screw 9,
The fixing screws 12 and 12' can also be installed extremely firmly without loosening.

Both the locking screw 9 and the mounting bolt 17 of the present invention are covered within the cylinder 6 of the clamping tool 8 and are not visible from the outside, and the heads of the fixing screws 12° and 12' that are screwed into the bracket 11 from above and below are slightly exposed. However, since it is shielded by the guardrail 1, it looks good, and when repairing or replacing the guardrail 1, the guardrail 1 can be easily removed by loosening the fixing screws 12 and 12' of the bracket 11. This is a simple and robust mounting device that has never existed before.
