Pedestrian handrail

The present invention relates to a handrail structure, and more particularly to a handrail that combines both material cost and structural strength.

According to the conventional handrail structure, it is applied to stairs, walls or walls, and provides auxiliary support for walking through the handrails, which helps the handicapped person or the elderly to use the hand, and also has the safety protection effect against falling. However, a common type of handrail structure is mainly made of strip-shaped logs, and a bracket is attached to the lower end of the log, so that the handrail of the log can be assembled on the stairs, the wall or the wall, but the purchase of the log is not easy, and the unit price High, resulting in a significant increase in the cost of handrails, which reduces the acceptance of the general public, and a large number of illegal logging will also cause environmental damage. This is the disadvantage of using the wood handrails, and another common handrail structure is a metal pipe. The main body is connected to the stair, the wall or the wall at the lower end of the metal pipe. However, since the metal pipe is a hollow pipe body, only a small area is formed when the bracket is screwed to the metal pipe, so that it is easy to occur. Looseness or the inability to withstand excessive external forces, resulting in the structural strength of the metal pipe handrail is insufficient.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention lies in the above-mentioned existing Missing, providing a handrail.

The plurality of splicing woods are formed in a block shape with at least one joint edge and at least one affixing surface, the splicing woods are connected to each other by the joint edges to form an extension of the armrest length, and the splicing woods are stacked on each other to form the armrest height And increasing the width, a plurality of adhesive layers are disposed between the joint edge and the bonding surface to form an adhesive bond of the splicing wood, and a coating layer is formed by pressing and coating on the entire surface of the splicing wood, so that The covering layer completely shields the splicing wood, and the handrail lock is provided with at least one handrail frame, and is selected by the handrail frame to be fixed at any position of the stairs, the wall or the wall surface.

Wherein, the splicing wood is formed with a toothed surface at the joint edge, that is, the bonding area of the joint edge can be improved, and the joint positioning effect of the splicing wood is also provided.

Wherein, the splicing wood is formed in a square shape with a plurality of edge lines, and the splicing wood is recessed with at least one micro-shaped groove at the edge line, and the covering layer is filled in the micro-shaped groove, thereby lifting the edge line The strength of the coating structure at the location.

Wherein, the splicing wood is provided with at least one notch, and the covering layer is filled in the notch, thereby improving the bonding strength between the splicing wood and the covering layer.

Wherein, the splicing woods are dried before being bonded, and the outer moisture is blocked by the coating layer.

Wherein, the coating layer is formed with a wood grain surface.

Wherein, the armrest is formed in a square column shape.

Wherein, the armrest is formed in a cylindrical shape.

Wherein, the armrest is formed in a semi-cylindrical shape.

The first main object of the present invention is that the splicing wood is processed by cutting the residual block of the wood, so that the splicing wood is formed by different three-dimensional squares with at least one joint edge and One less bonding surface, the adhesive layer is set at the joint edge of the two splicing woods, and the adhesive layer is placed on the bonding surface of the splicing wood, so that the splicing wood can be stacked and bonded to each other to form a long strip, and then spliced. The surface of the wood is covered with a coating layer, thereby allowing the handrail to have an overall surface appearance and maintaining the structural strength of the solid wood, thereby replacing the logs with the splicing wood, which not only can effectively reduce the material cost, but also has Cut the function of reusing the remaining material to improve its practicality.

A second main object of the present invention is that the splicing wood is formed with at least one joint edge and at least one affixing surface, and the joint edge is formed with a toothed surface, and the splicing wood is concavely provided with a micro groove at the edge line. In addition, the splicing wood is additionally provided with a notch, and the flank surface is used to improve the bonding area of the joint edge, and has the connection positioning effect of the splicing wood, and then the surface of the splicing wood is covered with a coating layer, and the coating is coated. The layer can simultaneously fill the micro-grooves and notches of the splicing wood, and the micro-grooves filled with the splicing wood can enhance the structural strength of the coating layer at the edge position, so that the coating layer is not easily separated by the edge of the splicing wood. Cracking and filling the gap of the splicing wood can also improve the bonding strength between the splicing wood and the cladding layer.

A third main object of the present invention is that the splicing wood can be formed with micro-grooves and notches in the defective parts such as defects, damages or uneven surfaces of the body, thereby retaining the bad parts of the splicing wood, thereby improving the utilization of the splicing wood. The rate can also increase the range of materials that can be used.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.
