Description

[Detailed explanation of the idea] "Industrial application field" This invention relates to handrails.

``Problems to be solved by conventional techniques and ideas'' Conventional handrails include those shown in FIGS. 5 to 7.

In the handrail shown in FIG. 5, a cylindrical body 105 made of vinyl chloride and having an opening 104 extending over the entire length in the peripheral wall is fitted into a holding member 103 made of aluminum that is attached to the tip of a bracket 101 with a screw 102. In this handrail, when fitting the cylinder 105 made of vinyl chloride to the holding member 103, the cylinder 105 is made of vinyl chloride, so it is hard and difficult to deform and is difficult to fit, and the workability is not necessarily good. If the cylindrical body 105 is made of vinyl chloride, it may be burned out by a mischievous cigarette or damaged by a knife. Furthermore, since the opening 104 is located at the bottom of the cylinder 105, it is not desirable for safety because a child may slip while holding the cylinder 105 or get his or her fingers caught. It may be visible and is not desirable in terms of appearance.

The handrail in Fig. 6 has a bracket 112 on a cylindrical body 111 made of stainless steel or aluminum.
Since the cylinder body 111 is fitted externally, the cylinder body 111 may shake inside the bracket 112.
The mounting position may not be accurate.

The handrail in FIG.
21 has an opening 122 in the peripheral wall and a holding groove 12 on the axis side.
3, an engagement plate 124 is fitted into the holding groove 123, and the tip of the bracket 125 is screwed onto the engagement plate 124 with a screw 126. With this handrail, there is a risk that a child may put his or her finger into the opening 122 of the cylindrical body 121, so it is not necessarily safe, and there is also a risk that the screw 126 is exposed outside and may be removed.

``Means for Solving the Problems'' Therefore, in view of the above circumstances, the present invention is easy to install, can be done with high precision, is safe, does not cause damage, and does not expose screws or other unnecessary items. In order to achieve this, the cylinder body 1 is made of a metal cylinder 1 made of an extruded shape, and there is a housing chamber 4 in the cylinder body 1 that receives and holds the tip of a bracket 21 which has an opening 2 in the peripheral wall and a holding groove 3 on the axis side. Support pieces 7, 7 are provided protrudingly from the lower part of the holding groove 3, and an opening 2 of the storage chamber 4 is formed.
A step 5 is formed on the inner wall of the housing chamber 4, and protrusions 6, 6 for engaging the cover 41 are protruded closer to the axis than the steps 5, 5 of the inner wall of the storage chamber 4, and the engagement plate 11 is inserted into the holding groove. 3, the adapter 23 is fixed to the tip of the bracket 21 which has a protruding flange 24 whose lower surface is formed into arcuate surfaces 24a, 24a, and the adapter 23 is housed in the storage chamber 4 with the flange 24 in contact with the stepped portion 5. Then, the adapter 23 is held on the engagement plate 11 by interposing the support piece 7 of the holding groove 3 and screwed with the screw 53,
This is a handrail in which connecting pieces 43, 43 extending to both longitudinal ends of a cover 41 are engaged with the protrusions 6, 6 in the opening 2 of the cylindrical body 1 to close the opening 2.

"Operation" The engagement plate is fitted into the holding groove of the cylindrical body, the flange of the bracket is brought into contact with the stepped part, the bracket is housed in the cylindrical body, and the supporting piece of the holding groove is interposed between the engagement plate and screwed to hold it. Then, fit the cover into the opening of the cylinder.

"Example" As shown in Figs. 1 to 4, there is a roughly cylindrical cylinder 1 made of aluminum made of an extruded section. A housing chamber 4 is formed to receive and hold the tip of the bracket having the bracket 3. Support pieces 7, 7 are provided protruding from the lower part of the holding groove 3. Step portions 5, 5 that bring the flange of the bracket into contact with the inner wall on the opening 2 side of the storage chamber 4
form. Further, a stepped portion 5 of the inner wall of the storage chamber 4,
a protrusion 6 for engaging the cover closer to the axis than 5;
6 is installed protrudingly.

The engagement plate 11 is formed to a size that can be fitted into the holding groove 3 of the cylindrical body 1, and screw holes 12, 12 for attaching a bracket, which will be described later, are cut at both ends.

The bracket 21 is made of an extruded aluminum body 22 and has a roughly U-shaped surface, and an adapter 23 which is cut from the aluminum extruded shape.

Flanges 24, 24 which contact the step portions 5, 5 of the opening 2 of the cylindrical body 1 and form the peripheral wall of the cylindrical body 1 are protrudingly provided at the tip of the bracket body 22. Flange 2
4 and 24 close the opening 2 of the cylindrical body 1 and form their lower surfaces into arcuate surfaces 24a and 24a so as to smoothly connect to the circumferential wall of the cylindrical body 1 when mounted on the cylindrical body 1. A support stepped portion 25 for the adapter 23 is formed at the upper end by the flange 24 at the tip of the bracket body 22;
Lateral through holes 26, 26 are bored in the support step 25, into which the adapter 23 is placed and screwed. Projection piece 2
7 performs positioning in the width direction when the tip of the bracket 21 is accommodated in the accommodation chamber 4. Mounting bolt through holes 31, 31 are provided at the base end of the bracket body 22.
to be drilled.

The adapter 23 is placed on the stepped portion 25, and is formed so that both ends protrude longer in the longitudinal direction than the bracket main body 23, and horizontal screw holes 28, 28 are formed at positions corresponding to the through holes 26, 26. The engagement plates 1 are provided at both ends protruding from the bracket main body 22.
Through hole 2 is located at the location corresponding to the screw holes 12, 12 of 1.
Drill holes 9 and 29.

Attach the adapter 2 to the stepped portion 25 of the bracket body 22.
3, and pass the screws 30, 30 through the holes 26, 26.
The bracket body 22 and the adapter 23 are integrated by inserting them into the screw holes 28 and screwing them into the screw holes 28, 28. The work of screwing the adapter 23 to the bracket body 22 is done at the factory. In addition, the bracket body 2
Bracket 2 that integrates 2 and adapter 23
1 can be formed as an integral part, and it is sufficient to consider the ease of manufacturing.

The cover 41 closes the opening 2 of the cylindrical body 1 and engages with the protrusions 6, 6, and includes a base piece 42 and a base piece 42.
The lower surface of the base piece 42 is formed into an arcuate surface 42a that continues to the peripheral wall of the cylindrical body 1 when the cover 41 is attached. There is an engaging protrusion 4 on the outside of the tip.
4, 44 are installed protrudingly.

To attach the handrail, the brackets 21 are placed on the wall surface 51 at predetermined intervals, and the mounting bolts 52 are inserted into the through holes 31 and 31, and then screwed. Next, cylinder 1
The engagement plate 11 is fitted into the holding groove 3 from the end of the cylindrical body 1 and positioned at a predetermined position, and the housing chamber 4 of the cylindrical body 1 is
Insert the tip of the bracket 21 into the flange 2.
4, 24 against the stepped portions 5, 5, and screws 53, 5
3 into the through holes 29, 29 and screw holes 12, 1.
2. Subsequently, the engaging protrusions 44 of the connecting pieces 43, 43 of the cover 41 are engaged with the protrusions 6, 6, thereby closing the opening 2 of the cylindrical body 1. Thereafter, caps (not shown) are fitted onto both ends of the cylindrical body 1, respectively.

``Effects of the invention'' As mentioned above, this invention closes the opening of the cylindrical body with a cover and does not expose any unnecessary items such as screws to the outside, so there is no risk of children getting their fingers caught in the opening, making it safe. There are no screws to remove, and the exterior is clean and looks great.
Further, since the bracket can be attached from below to the engagement plate which freely slides in the longitudinal direction within the holding groove and is screwed, the attachment is easy and accurate. If the cylindrical body is made of aluminum, it will not be burned out by a mischievous cigarette or be damaged by a knife. Furthermore, since the cylinder and the bracket can be formed from aluminum extrusion, they can be provided at low cost.
