Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is useful when an elderly or sick person bends down to use the toilet, etc.
Regarding the handhold stick that is used as a handle.

[Prior art and its problems]

The applicant previously filed Japanese Patent Application No. 61-211410 (Patent Application No. 4
-No. 70461) An application was filed regarding a handle bar to be attached to toilets, etc. as a method for attaching a handle bar between pillars.

However, as a result of subsequent consideration, it was found that if this handle bar was inserted into the insertion hole 2b of the fixture 2,
It turns out that if you hold it in your hand, it will rotate. When this handhold rod rotates, it becomes less useful as a handhold stick.

Furthermore, a method of fixing the handle bar 1 as shown in FIG. 14 has also been proposed. In Fig. 14, a stuffing material 4 is inserted into the back of the insertion hole 2b of the fixture 2 of the handle bar 1 to the pillar 3.
Insert.

Meanwhile, the hollow portions 15 at both ends of the handle bar 1 are inserted. The core 15 has a protruding portion 15t protruding from its outer end surface, and is fixed to the handle bar 1 of the core 15. After inserting the handle bar 1 into the insertion hole 2b, the screw 12 is screwed into the set screw hole 13. 14 is a spanner hole for rotating the spanner.

Although this proposal has achieved the purpose of preventing the rotation of the handle bar 1, since the pressure is applied to the handle bar 1 only with the screw 12, the handle bar 1 is unavoidably attached to the screw 12.
There is a problem with slipping.

[Means for solving problems and their effects]

In order to solve the above-mentioned problems of the prior invention, the present invention has the following objectives: "A wedge body 6 in which at least two or more units are combined is inserted into the hollow portions at both ends of the handle bar 1, and each unit of the wedge body 6 is A tapered hole 6a is formed, and a tapered body 7 is inserted into this tapered hole 6a in a wedge shape 7. The tapered body 7 is inserted from the outer end of the fixture 2, and a nut 8 is stretched on the inner end of the tapered body 7.
The screw 9 is screwed into the tapered hole 6a and the wedge body is inserted into the tapered hole 6a.

In this way, the present invention prevents the handle bar 1 from rotating when a person grasps it.

[Description of Examples]

Examples of the present invention will be described below.

In the drawings: 1: It is preferable that the inner periphery of the opening at both ends of the handle bar protrudes inward in a somewhat annular shape. In this case, the handle bar is cut with a desk cutter.

2: Attachment 2a: Column abutting portion 2b: Hand rod insertion hole 3: Pillar 4: Filler, which is stuffed into the insertion hole 2b when the spacing between the columns is larger than the length of the hand rod 1.

5: Nail 6: A wedge body which is a combination of two or more units U to be inserted into both hollow ends of the handle bar 1, and has a tapered hole 6a inside.

Further, a spring bar 9 is attached to the outer end of the tapered hole 6a.
is inserted.

7: A tapered body inserted into the tapered hole 6a,
A spring board 8 is stretched on the inner end thereof.

The rod 9 passes through the tapered body 7 and connects with the nut 8.
screwed into.

8: A nut stretched or inserted into the inner end of the tapered body 6.

9: A screw rod that is screwed into the nut 8 at the inside end of the tapered body 6 through the screw insertion hole 10 at the outside end of the fixture 2.

10: Screw insertion hole of fixture 2.

11: A retaining ring such as a rubber ring for tensioning the pair of units u and u.

Its action will be explained below.

The handle bar 1 is attached to the pillar 3 using the fixture 2, but the details are described in the specification of the earlier application and will therefore be omitted.

In the present invention, the wedge bodies 6 are inserted into the hollow both ends of the handle bar 1 in advance.

A tapered hole 7 is inserted in advance into the tapered hole 6a of the wedge body 6 as shown in FIG.

On the other hand, a threaded rod 9 is inserted through a threaded insertion hole 10 at the outer end of the fixture 2, passes through the tapered hole 7a and the tapered body 7, and is threaded into the nut 8 of the tapered body 7.

When the screw rod 9 is turned with a screwdriver, the nut 8 bites into the tapered hole 6a in the direction of arrow A in FIG. It expands toward the inner circumferential surface of the rod 1 in the direction of arrow B in FIG. 2, and thus the wedge body 6, the handle rod 1, and the fixture 2 are integrated as shown in FIG.

That is, the biting force of the tapered body 7 is pressed against the inner circumferential wall of the handle bar 1 of the unit u of the wedge body 6 and the inner wall of the fixture 2.

In this way, the handle bar 1 will not rotate even if it is held by hand.

In addition, when stuffing the stuffing 4 into the insertion hole 2b as shown in FIG. 3, it is necessary to make a screw insertion hole 4a in the stuffing 4 as shown in FIG. In addition, Fig. 3 shows the wedge body 6.
Shows the state when tightened.

Note that FIG. 7 shows a case where the tapered body 7 has a triangular cross section.

FIG. 8 shows the inner end surface of the wedge body 6 in this case, and the ninth
The figure also shows the outer end surface.

FIG. 10 is a front view of the inner end surface when the tapered body 7 is o-shaped, and FIG. 11 is a front view of the outer end surface.

12 and 13 show the inner and outer end surfaces of the tapered body 7 having a square cross section and the wedge body 6 having four units u. The shape of the tapered body 7 is not particularly limited.

Note that if the inner circumferential edge of the outer end is made to protrude t as shown in FIGS. 2 and 3, after the wedge body 6 is inserted into the handle bar 1 without being tightened by the tapered body 7, the wedge body 6 can be inserted into the handle bar 1 without being tightened by the tapered body 7. When the body 6 is tightened, the wedge body 6 does not come out of the handle bar 1, so that the wedge effect increases.

〔Effect of the invention〕

As mentioned above, the handle bar of the present invention has the advantage of being very safe, since there is no risk of it rotating even if you hold it in your hand in a restroom or the like.

That is, in the present invention, the insertion hole 2 of the tapered body 7
Since the handle bar 1 is fixed to the fixture 2 by the wedge action in b, the fixing force is extremely strong.

In the present invention, first, the handle bar 1 is suspended between the fixtures 2, 2, and after the fixtures 2, 2 are fixed to the pillars 3, 3, the connection between the pillar 3, the handle bar 2, and the wall is suspended. Using the space, the handle bar 1 can be fixed from the outside by the wedge action of the tapered body 7. That is, the present invention has the advantage that the handle bar 1 can be fixed using a narrow space such as a toilet.
