Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a handrail arranged around a toilet bowl for supporting the body of a physically handicapped person when he uses the toilet.

Traditionally, in this type of handrail for people with physical disabilities, the welded part was exposed at the part where the joint body was interposed in the middle of the handrail, and the outer circumferential surface became uneven, and even if this was slightly uneven, it could cause injuries such as stab fingers This makes it unsuitable for use as a structure for physically disabled people, which requires careful attention, and requires post-processing such as polishing, making the work complicated.

The present invention aims to provide a handrail for physically disabled persons that can eliminate these drawbacks.

Next, the present invention will be explained based on the drawings.

FIG. 1 shows an embodiment of the handrail structure according to the present invention in the form of an exploded view, and each of the handrails has one
A pair of U-shaped circular tubes 3, 3 having a wall fixing part 11 and a fixing metal fitting 12 at the ends are arranged at a required parallel interval, and the proximal ends of both circular tubes 3, 3 are connected by a mounting tube 3'. The cylinder 3 on one side is attached to the side wall with a fixing fitting 13, and the cylinder 3 on the other side is supported on the floor with a mounting tube 3'. Note that the handrail portion is formed by U-shaped circular tubes 3, 3.

In the above configuration, the present invention is characterized in that the connection between each member (for example, the fixing fitting 12 and the circular tube 3 or the circular tube 3 and the mounting tube 3') is connected by the joint body 1 having a special structure. . The detailed structure of such a joint body 1 is shown in FIGS. 2 to 6, and this shows the case where it is used to connect a circular pipe 3 and a mounting pipe 3'. Figure 2 is a front view of the joint body 1, Figure 3 is a side view taken along the line shown in Figure 2, and Figure 4 is a side view of the joint body 1.
The figure is a cross-sectional view taken along lines from Figure 2, Figure 5 is a plan view taken along lines from Figure 2, and Figure 6 is a cross-sectional view taken along lines from Figure 2.
FIG.

1 is a T-shaped joint body;
As shown in FIG. 2, it is composed of a horizontal pipe a and a vertical pipe b that is perpendicular to the horizontal pipe a and connected to the center of the horizontal pipe a. And on both ends of this horizontal pipe a, circular pipes 3,
3 are connected, and a mounting pipe 3' is connected to the vertical pipe b. The horizontal pipe a forms the central part and the circular pipe 3
a first large-diameter portion 1a having an outer diameter substantially equal to the outer diameter of the circular tube 3; It consists of a first receiving part 2. Note that the width of the first large diameter portion 1a is set smaller than the outer diameter of the circular tube 3. On the other hand,
The vertical pipe b is formed with a second large diameter part 1b having an outer diameter substantially equal to the outer diameter of the circular pipe 3, and a second step part 2b below the second large diameter part, and has an inner diameter equal to the inner diameter of the circular pipe 3. and a second receiving portion 2' having approximately the same outer diameter. The upper end portion of the second large diameter portion 1b is provided with the first portion of the horizontal pipe a.
An arcuate recess 3b is formed, having a size into which approximately half of the outer circumferential surface of the large diameter portion 1a fits. The horizontal pipe a and the vertical pipe b are fitted together and the upper edge of the recess 3b is fixed to the outer peripheral surface of the first large diameter portion 1a of the horizontal pipe a to form the joint body 1. . Therefore, vertical pipe b
An arcuate recess 3 provided at the upper end of the second large diameter portion 1b of
b is in close contact with the outer peripheral surface of the first large diameter part 1a at the upper edge corresponding to the first large diameter part 1a of the horizontal pipe a, but the width of the first large diameter part 1a is larger than the outer diameter of the circular pipe 3. That is, since it is narrower than the outer diameter of the second large diameter part 1b, the first large diameter part 1
An arc-shaped gap 4 into which a lower portion of the end of the circular tube 3 can be fitted is formed between the outer peripheral surface of the first receiving portion 2 located on both left and right sides of a and the lower edge of the recess 3b. Thus, during assembly, the circular tube 3 is inserted into the first receiving portions 2 on the left and right sides of the joint body 1, and the ends of the circular tube 3 are brought into contact with the first step portion 2a. At that time, the lower part of the end of the circular tube 3 is inserted through the gap 4 and located inside the vertical tube b, and the end of the circular tube 3 located inside the vertical tube b and the first The large diameter portion 1a is welded inside the vertical tube b. On the other hand, the second
A mounting pipe 3' is attached to the receiving part 2' and has an outer diameter and an inner diameter that are the same as the outer diameter and inner diameter of the circular pipe 3, and one end is fixed to the floor surface or to the middle of a handrail part different from the handrail part.
By extrapolating and fixing the other end, the construction of the handrail for the handicapped person is completed. In this embodiment, a bolt insertion port 6 is provided above the large diameter portion 1a of the horizontal pipe a, and a bolt engagement port 7 is provided below.On the other hand, a female threaded portion is provided in the middle of the mounting pipe 3'. A bushing 10 having a shape is fixed thereto. Then, insert the mounting tube 3' into the second receiving part 2', insert the bolt 8 from the bolt insertion port 6, screw it into the female threaded part of the bush 10, and engage the head of the bolt 8 with the opening edge of the bolt engagement port 7. At the same time, the mounting pipe 3' and the joint body 1 are fixed together. Reference numeral 9 denotes a cap that is engaged with and covers the bolt insertion opening 6 in order to connect the mounting pipe 3'.

When using handrails for people with physical disabilities, they are often used by sliding the hand while keeping the hand on the handrail, and there was a risk of injury to the hand if there were any protrusions on the handrail. is safe because there is no level difference at the joint between the joint body, the circular pipe, and the attached pipe. Moreover, since the joint body and the circular pipe that constitutes the handrail are fixed, they are easy to use without any wobbling, and the welded part A between the joint body and the circular pipe is the outer peripheral surface of the horizontal pipe surrounded by the vertical pipe. Since the welded part is located on the outer surface of the joint body, the welded part is not exposed and there is no risk of injury from the welded part. Furthermore, there is no need for post-treatment of the welded portion, which has the effect of reducing costs.

In addition, since the end of the circular tube is inserted into the first receiving portion and the outer peripheral surface of the end of the circular tube is in contact with the opening edge of the recess, even if force is applied to the circular tube, the force will not be absorbed. It is received by the first receiving part and the opening edge of the recess, no force is applied to the welded part between the circular tube and the first large diameter part, and there is no chance of the welded part coming off.
