Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a screen hanging bar that is attached to the end of a tapestry or roller blind screen.

<Prior Art> A hanging bar is attached to the end of the screen of a tapestry or roller blind. The hanging bar consists of a half-cylinder body that can be divided into front and back parts, and connecting pieces that are integrally formed on the upper and lower edges of the half-cylinder body. to hold. However, the connecting pieces of conventional half cylinders are vertically symmetrical, with one side shaped like a protrusion and the other shaped like a channel, but because of the vertical symmetry, there is little play before joining, making it difficult to attach to thick screens. It was difficult, and there was also the problem that the pressure bonding after bonding was insufficient and the omissions tended to fall off when extra copies were added to a thin screen.

<Object of the Invention> An object of the present invention is to provide a hanging bar that is easy to install and has a strong grip on the screen, regardless of the thickness of the screen.

<Structure of the Invention> In order to achieve the above-mentioned object, the hanging bar of the present invention is composed of a front and rear half cylinder body and a connecting piece integrally formed on the upper and lower edges thereof, and a connecting piece 1 on the screen end gripping side. For example, the upper edge binding piece is a combination of a protrusion and a channel, or the opposite underlined binding piece is a combination of a protrusion and a hook. Since the upper edge connecting pieces that grip the screen are connected to each other with sufficient play until the underlined connecting pieces are connected, it is possible to sandwich even thick screens that could not be held with conventional devices. When the underlined connecting pieces are combined, the tip of the other upper edge connecting piece tends to be elastically pressed against the base of one projecting piece-like upper edge connecting piece, making it possible to securely grip even thin screens. can.

<Example> The suspension/hook of the present invention will be explained based on an example shown in the drawings. As shown in FIG. 1, the tapestry screen 10 is held at both ends by a pair of upper and lower hanging bars 12,20. The upper hanging bar 12 is fixed to the ceiling etc. by a hanger 11, and the lower hanging bar 20 is free, but depending on the shape of both and the screen l.
The structure for gripping the end of the O is exactly the same. The hanging bar 20 includes front and rear half cylinders 21, 22 and left and right caps 14.
Both are synthetic resin materials with elasticity.

As shown in FIG. 2, the upper edge of one of the half cylinders 21 has an upper edge coupling piece 23 extending in the radial direction, and the lower edge thereof has a protrusion extending in the chord direction. The underlined connecting pieces 25 are each integrally formed. At the upper edge of the other half cylinder 22, there is a channel-shaped lower edge connecting piece 24 that engages with the upper edge connecting piece 23 on the other side, and at the lower edge, it also engages with the underlined connecting piece 25. The hook-shaped underlined connecting pieces 26 are each integrally formed.

When the underlined connecting pieces 25 and 26 are combined, the tip of the upper edge connecting piece 24 tries to press against the base of the mating upper connecting piece 23 due to the elasticity of the half cylinders 21 and 22, so that the bar 20 is attached to the screen. Even if 10 is thin, its end 13 can be firmly gripped.

To connect the front and rear half cylinders 21 and 22 of the bar 20 with the end 13 of the screen 1o in between, first, as shown in FIG. Apply the end 13 of the screen 1o to the outer surface, and then connect the channel-shaped H edge coupling piece 24 of the other half cylinder 22 to the opposing protrusion-shaped upper edge coupling piece 23 and the screen as shown by the arrow. Fit it into the end 13. At this time, there is sufficient play between the upper edge joining pieces 23, 24, so that the end 13 of the thick screen 1o can also be sandwiched. Next, as shown in FIG. 4, the hook-shaped underlined connecting piece 28 of the other half cylinder 22 is pressed against the protruding underlined connecting piece 25 of one half cylinder 21 as shown by the arrow. When hung, the two are firmly connected by the elasticity of the half cylinders 21 and 22, and the tip of the upper edge connecting piece 24 comes into contact with the inner root of the mating upper edge connecting piece 23, as shown in FIG. Firmly grasp the end 13 of the screen 1o between them. By reversing these operations, you can remove the screen from the hanging bar. Although not shown,
The hanging bar can also be used as a weight attached to the tip of the screen of a roll blind.

As shown in FIG. 5, if a double-sided tape 15 is attached to the outer surface of the upper edge coupling piece 23 of the half cylinder body 21, the end of the screen can be temporarily fixed, making installation easier.

As shown in FIG. 6, one or both of the inner root portion of the upper edge connecting piece 23 of the half cylinder 21 and the tip portion of the upper edge connecting piece 24 of the half cylinder 22 are finished in a tooth shape. Keep it 5
The gripped end portion 13 of the screen 1o is securely held without slipping.

<Effects of the Invention> As mentioned above, the hanging bar of the present invention has a large amount of play when the end of the screen is sandwiched between the front and rear half cylinders, so it has a thickness that cannot be sandwiched with the conventional hanging bar. Also, when the front and rear half cylinders are connected, the tip of the connecting piece on the screen end gripping side elastically attaches to the base of the connecting piece on the side gripping the screen end. Since it is crimped, it has the excellent effect that there is no risk of it falling off even when attached to a thin screen.
