Description

[Detailed Description of the Invention] The present invention relates to a device that buffers a weight bar from colliding with a screen mounting portion when a roll blind is rolled up.

2. Description of the Related Art Shutter devices and the like are known in which a pump-type shock buffer mechanism is attached to the shutter. (For example, devised in 1982-165095) However, it is not appropriate to install a large shock absorbing mechanism like the previous proposal for something like a roll blind where the entire mechanism needs to be significantly simplified. Not.

On the other hand, normal roll blinds are not equipped with a suitable buffer mechanism, so if you let go of the operating cord while the screen is rising, the roll pipe will accelerate, and when the weight bar reaches its upper limit, it will collide with the screen support frame and cause serious damage. Not only did it generate sound, which caused premature damage to the screen, but it also sometimes sagged somewhat due to recoil after reaching the upper limit.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and to provide a winding shock absorbing device that can be easily attached to a screen support frame and that can sufficiently achieve the intended purpose for use in roll blinds. .

The structure of the roll blind winding buffer device of the present invention to achieve the above object will be explained with reference to the drawings. As shown in Fig. 1, the screen support frame is provided with a structure that diagonally faces the rear surface of the weight bar when the screen is rolled up. A shock absorbing member such as an elastic plate-shaped shock absorber 6 or a shock absorbing plate 7 is provided to prevent the rise of the shock absorber.

In the roll blind equipped with the device of the present invention, when the screen is rolled up, the elastic plate-shaped buffer member disposed on the screen support frame obliquely contacts the rear surface of the weight bar, so the contact between the contact surfaces becomes stronger over time and the impact is reduced. The generation of noise is suppressed as much as possible, and at the end of hoisting, the weight bar is clamped and pressed against the front of the support frame via a buffer member, preventing it from falling due to reaction when hoisting is stopped. Ru.

Embodiments will be described below. FIG. 1 is a perspective view of a roll blind having a winding shock absorbing device according to the first embodiment of the present invention, and FIGS. 2 and 3 are lines AA and B-- It is a sectional view taken along the B line.

In the drawing, 1 and 1 are left and right L-shaped brackets, 2 is a connecting plate between both brackets, and both of them together constitute a support frame.
An upper winding part 5 of a screen 4 with a weight bar 3 attached to the lower end is installed between the brackets 1 and 1.
A buffer body 6 made of an elastic material is attached to the front surface of the connecting plate 2, and a buffer plate 7 is also attached to the lower side of the connecting plate 2, each forming a buffer section. Buffer body 6 and buffer plate 7
Only one of them may be used, and the buffer member as described above may not be provided on the entire surface of the connecting plate, but may be provided on a part of the connecting plate as described below.

Figures 4, 5, and 6 show examples in which a buffer member is provided in a part of the connecting plate, and 11 is a buffer constructed by molding an elastic material such as rubber or synthetic resin into a J shape. The adhesive material 12 is applied to one side of the body, and 1
3 is a buffer plate constructed by bending a spring plate; 14 is a buffer plate with a holding portion 15 provided above; these are all attached to the connecting plate 2, bracket 1, or wall surface using adhesive or small screws (not shown), etc. , to be used by fixing it to a ceiling surface, etc.

As shown in the above-mentioned embodiments, the roll blind having the shock absorbing device according to the present invention has a weight bar 3 when rolled up.
When the weight bar reaches its upper limit, it hits the buffer member and is buffered, so it does not generate any unpleasant noise, and there is no risk of damaging the screen or the mounting part, and the weight bar is pressed against the buffer member at the upper limit position. This prevents it from swinging or sliding down.
