Description

[Detailed Description of the Invention] This invention relates to a handrail in which a cover made of synthetic resin can be removably attached to the handrail core of a staircase or a hallway.

In general, this type of handrail has a metal or hard material handrail core with a synthetic resin cover that matches the shape of the handrail core, and some are also crowned with this. Due to dimensional errors in the manufacturing of the materials, the resulting dimensional differences, and dimensional changes due to changes in temperature, the gap between the two crowns loosens and rattles, etc. It has the disadvantage that it is impossible to attach and detach.

This invention solves these drawbacks by attaching a crown to a longitudinal metal core and providing a locking protrusion on one longitudinal edge of the crown. A bending portion is formed on the other end thereof, and a bending locking portion having elasticity that engages with the bending portion is formed on the other end edge.

Furthermore, a longitudinal strip having several pressure-contact protrusions made of a soft synthetic resin that press-contacts the longitudinal core material is integrally molded on the opening edge of the crowned body.

Therefore, according to this invention, it can be easily attached to the outer periphery of the handrail core material, it can be attached and detached freely, there is no need to worry about the capping body loosening or moving, and the dimensional error between the core material and the capping body can be reduced. Even if this occurs, the bent portion and the bent locking portion are elastically held together and firmly fixed.

Next, an embodiment of this invention will be explained with reference to the drawings.The handrail body 1 consists of a longitudinal core material 2 made of a light metal such as aluminum or synthetic resin, and a hard or semi-hard synthetic resin coated from the outer periphery of the longitudinal core material 2. It is composed of a crowned body 3.

The crowned body 3 has a locking protrusion 5 on one end edge in the longitudinal direction.
A bending portion 4 is formed with a bending portion 4, and a bending locking portion 6 having elasticity that engages with the bending portion 4 is formed on the other end edge.

Further, on the opening end edge 11 in the longitudinal direction of the crowned body 3, a longitudinal strip 7 is provided with several pressure-contact protrusions 8 on the surface made of soft synthetic resin and press-contacts the longitudinal core material 2 on the inside. are integrally molded.

Reference numeral 9 indicates a fixture for supporting the handrail body 1, and reference numeral 10 indicates a mounting leg to be attached to the wall surface 12.

This device has the above-mentioned configuration, and when fitting the crowning body 3 onto the longitudinal core material 2, the crowning body 3 is placed with the retaining part downward from the outer periphery of the core material 2, and the bending locking part is covered with the crowning body 3. 8, if the locking protrusion 5 of the bent part 4 is engaged in a tensile state, it can be firmly attached and fixed, and the crowned body 3 can be easily removed by performing the opposite operation. be.

As mentioned above, this design allows the capping body to be easily attached to the longitudinal core material of the handrail from the outer periphery, and even if a dimensional error occurs during manufacturing, the engaging part of the capping body can be bent as appropriate. It has excellent adhesion properties.

Then, the rotation of the crowned body after it has been fitted is controlled by a longitudinal strip provided with several pressure-contact protrusions made of soft synthetic resin that press against the longitudinal core material provided at the opening edge of the crowned body. It has the excellent effect of being able to be firmly and stably fixed without twisting or shifting due to the material.

Further, a bent portion having a locking protrusion provided on one end edge in the longitudinal direction of the crowned body, and a bent locking portion that engages with the locking protrusion of the bent portion on the other end edge are formed respectively. Therefore, it is easy to attach the crowned body to the longitudinal core material, and it can also be detached freely, which is very convenient, and the face is held elastically and can be bent easily. It has the effect of not having to worry about damage etc.
