Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an aluminum handrail.

[Conventional technology]

Handrails attached to stairs and windows of high-rise apartments conventionally consist of hollow tubular round handrails that are held by support rings attached to the body at both ends.

[Problem that the invention attempts to solve]

According to such conventional technology, since both ends of the handrail bar are simply inserted and held in the support ring, the handrail bar easily turns when the handrail bar is gripped and turned. If the handrail rotates in this way, it will not be stable when gripped, and it is especially dangerous for handrails attached to the windows of high-rise apartments.

Therefore, it is possible to fix the handrail bar to the support ring by drilling a locking hole toward the handrail bar from around the support ring and fixing it with screws, but this work can be done after the handrail bar is installed. The disadvantage is that the screws are visible from the outside as it is a lot of work, and there are some places where screws cannot be installed, so it is not possible to fix everything with screws like this.

[Means for solving problems]

Therefore, the present invention is characterized in that a partition is formed in the diameter direction of the hollow tubular round bar, and a protrusion that locks the partition is provided in the support ring.

[Effect]

According to the above configuration, the partition of the handrail bar is fitted between the protrusions of the support ring fixed to the rod body, and the handrail bar can be inserted and held in the support ring so as not to rotate.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is an overall perspective view, Fig. 2 is a partially cutaway front view, and Fig. 3 is a partially cutaway plan view. A partition 2 is passed through the entire length in the diametrical direction on the inside, and a groove 3 is provided on the outside at a location corresponding to the position of the partition 2, if necessary.

4 is a support ring having a diameter that allows the handrail bar 1 to fit therein, and has an opening 5 at one end and a closing wall 6 at the other end;
This closing wall 6 has a hole 7 for attachment to the body, and two pairs of support protrusions 8 and 9 are protruded from the inside at a width into which the partition 2 of the handrail bar 1 fits. . 10 is also a support ring, and has an opening 11 at one end and a closing wall 12 at the other end, and inside this closing wall 12 there is a pair of support protrusions 13 and 14 similar to the support ring 4 described above.
There are two sets protrudingly provided, and a locking piece 15 is formed on the outside and a screw hole 16 is provided.

According to the above configuration, first, the support ring 4 is fixed to the rod body by inserting the screws 17 into the holes 7. Next, one end of the handrail bar 1 is inserted into the support ring 4 so that the partition 2 of the handrail bar 1 is fitted between the support protrusions 8 and 9 of the support ring 4. At this time, it is preferable to check the position of the partition 2 using the groove 3 and fit it between the support projections 8 and 9.

Next, attach the other support ring 1 to the other end of the handrail bar 1.
1, insert the partition 2 between the support protrusions 13 and 14, apply the locking piece 15 to the body, and then tighten the screw hole 1.
6 and fix it with screws 18. By the above operations, the handrail bar 1 is fixed to the body and does not rotate within the support rings 4, 11.

Although two types of support rings were provided in the above embodiment, it is also possible to use only one type of support ring.Also, although two sets of support protrusions were provided in the above embodiment, two pairs of protrusions were provided in addition to the support protrusions. It is also possible to protrude in parallel,
Alternatively, a combination of protrusions and protrusions may be used.

[Effect of idea]

According to the present invention having the above-described structure and function, a partition is formed along the entire length in the inner diameter direction of a hollow tubular round bar made of aluminum, and a support protrusion is formed within the support ring to support the partition. By sandwiching the partition between the protrusions and preventing the handrail from rotating, the handrail can be fixed without rotating.

Further, during assembly, the partitions are simply fitted between the protrusions and there is no need to screw them from the outside, so that workability is good and there are no inconveniences such as visible screws on the outside.

Furthermore, by passing the partition through the handrail bar, a reinforcing effect is created, and safety in terms of strength can be measured.

Claims (1)

[Scope of utility model registration request] In a handrail consisting of a handrail made of a hollow tubular round bar and a support ring attached to a rod body to support the handrail, a partition is passed along the entire length in the diametrical direction inside the handrail, and a partition is passed through the entire length inside the support ring's closing wall. A handrail characterized in that a protrusion for preventing rotation of a handrail bar that locks an end of the partition is provided in a protruding manner.
