Description

  The present invention relates to a headboard connection structure for connecting headboards disposed on a handrail or the like.

  As for the headboard disposed at the upper end of a handrail or the like of a house, the two headboards are connected to each other by a joint member at adjacent ends. As a conventional joint member, what was described in patent document 1 is illustrated.

  The joint member described in Patent Document 1 covers a cover body made of a hard synthetic resin molded member having an appropriate width formed by forming an inner shape to be provided at least on the outer periphery of the upper half of the headboard along the headline butting line. Projected to be inwardly refracted engagement fitting edges that engage from the lower side with a step edge structure such as a draining edge of the headboard located at both ends of the main body, and located on the inner surface side of the cover main body and its width In the center of the direction, a clamping plate that extends in the direction of the abutment surface is integrally formed, and the tongue plate strip structure in which the free end abuts against the clamping plate on the inner surface of the end member of the headboard is elastically biased on both sides. And integrally molded.

When the clamping plate is pushed into the gap between the ends of the caps where the joint members are butted together, the engagement fitting edge slides along the surface of the caps due to the elasticity of the cover body, and the stepped structure And engage from below. At the same time, the tongue-shaped plate striations projecting on both sides of the sandwiching plate get over the thickness of the headboard while being pushed against the elasticity so as to be accommodated in the plane, and when it gets over the elastic plate, The free end contacts the inner surface of the top plate. Therefore, the joint member is fixed to the headboard by the engagement fitting edge and the tongue-shaped plate ridge structure, is securely and firmly attached, and does not easily fall off the headboard.

  However, in the above-mentioned joint member, the engagement fitting edge must be engaged from the lower side to the stepped structure of the lower end portion of the headboard while enabling expansion along the surface of the headboard by the elasticity of the cover body. There are certain restrictions on the size and shape of the engagement fitting edge. For this reason, there is not much covering over the entire width of the draining edge or the like forming the step edge structure, and a gap called “dust” is often generated at the lower end edge portion between the connecting end portions of the headboards. The connection end of the headboard is in a so-called cut-off state. There is a risk of injury such as sticking. Since safety is required as a quality performance of a house or the like, such dust becomes an important problem to be solved. It is also desirable to eliminate dust from the viewpoint of affecting the appearance when looking up. Generally, it is conceivable to eliminate dust by embedding putty, caulking, etc., but this is a time-consuming work, and as described above, dust is attached to the lower edge of the connecting end of the headboard. Since it occurs, it is also a difficult position to work, and the poor workability is highlighted.

  The present invention has been made in view of the circumstances as described above, concealing the dust at the lower end edge generated between the connecting ends of the caps, and is difficult to catch the wrapping fingers on the connecting end of the caps. Thus, it is an object of the present invention to provide a headboard connection structure that improves the appearance when looked up, as well as safety as a handrail, and has good workability.

  The present invention has the following features in order to solve the above problems.

  Second, in the first feature described above, the tip of the fixed piece of the dust cover member is disposed in contact with or close to the lower end of the fixed piece of the head cover.

According to the first feature of the present invention, the lower end edge of the connecting end of the headboard is covered with the collar of the concealing member disposed on the lower side between the connecting end portions of the two headboards. Therefore, it is difficult for a finger that has entered the lower end edge of the connecting end of the headboard in the handrail to be caught on the connecting end of the headboard, thereby preventing the occurrence of injury. Safety as a handrail is improved. Also, dust is less visible and the appearance when looking up is improved. Moreover, dust concealment is realized by a simple operation of arranging dust concealment members, and the workability is improved. In addition to this, the collar portion can be cut off at the projecting portion, and can be processed to an appropriate size at the construction site, so that the construction property of dust concealment is further improved.

  Further, according to the second feature of the present invention, in addition to the above effects, the area of the fixing piece of the dust concealment member is expanded, and the adhesive strength when fixing to the headboard using an adhesive is increased. A dust concealing member is stably disposed between the connecting ends of the two headboards.
