Description

The present invention relates to a roll screen with a guide for the purpose of preventing turbulence and kinking that occurs when a sunshade member installed on a window frame is rolled up, and in particular, a roll screen with a guide suitable for a narrow and long window. About.

  In recent years, a roll screen that raises and lowers a shading shielding member in the vertical direction inside the window frame is preferred and is often used. Conventionally, many inventions have been proposed regarding the guide structure of the shielding member so that this type of roll screen can be lifted and lowered smoothly manually or automatically when the shielding member moves up and down.

For example, guide rails that guide both ends of the shield member to be wound are arranged on both sides so that the shield member moves up and down along the guide rail groove so that the shield member can be wound around the winding shaft without meandering and kinking. A rolled screen is known (for example, Patent Document 1).
In addition, a bracket having a side plate that rotatably supports both ends of the winding shaft is fixed to the ceiling plate, and a guide wire is provided in parallel along the elevation surface of the shielding member, and the end of the guide wire is provided. There is a roll screen that is fixed to a weight bar to prevent kinking of the shielding member (for example, Patent Document 2).

JP 2000-160966 A JP-A-6-129178

In the roll screen of Patent Document 1, the construction of the guide rail is complicated and troublesome, and the cost is high. In addition, as in Patent Document 2, a guide wire that is directly fixed to a weight bar cannot sufficiently prevent kinking of an elongate sunshade member, and it may be wound into a bamboo stalk shape to fully function. I can't show it. Furthermore, since it is provided along the raising / lowering surface of the sunshade member, it may interfere with the winding operation of the sunshade member.

The present invention solves these problems, does not require complicated installation work, with a simple structure can effectively prevent turbulence and kinking of the awning member, with a guide that can perform smooth winding The purpose is to provide a roll screen at low cost.

The present invention relates to a roll screen comprising a bracket composed of a fixing plate that is fixed to a window frame on a wall surface and both side frames that support both ends of a take-up shaft wound with a sunshade member, and inside the side frames at both ends of the bracket. It has a linear guide that is positioned and has an upper end fixed to the inner surface of the bracket and hangs down, is inserted through through holes formed in both ends of the bottom member of the sunshade member, and the end is detachably fixed to the floor surface. It is characterized by that.

You may adhere the upper end of the said linear guide to the inner surface of the said bracket via the elastic member which can be expanded and contracted. Furthermore, it is preferable to arrange a guide roller in the linear guide passage of the bracket.
Further, a fixing member can be attached to the end of the linear guide, and the linear guide can be detachably fixed to the floor surface.

In the present invention, the linear guide that is fixed to the inside of the bracket installed on the window frame and hangs in contact with both side surfaces of the winding shaft is fixed, so that the raising and lowering of the sunshade member can be reliably and safely guided. it can. In particular, when the roll screen is a sunshade member having a small window and a long length, it is possible to provide an inexpensive roll screen while effectively preventing the sunshade member from being disturbed or kinked.
The ratio of the width and length of the sunshade member is generally suitable for a size of 1 to 10 to 15 although it depends on the material of the sunshade member.

In the roll screen with guide according to the present invention, since the linear guide is fixed to the bracket via the elastic member that expands and contracts, the length can be adjusted when the linear guide is simply attached to the floor surface, and the linear guide is tensioned. Since it can be maintained, it is possible to completely prevent the awning member from being kinked.

In the roll screen with guide of the present invention, the linear guide fixed to the bracket of the winding shaft passes through the bottom member of the sunshade member, and its end is fixed to the floor surface. The member is not kinked or wound up into a bamboo shoot, and a reliable operation can be achieved. In particular, in an awning member having a length to width ratio of 10 times or more with respect to the lateral width and a large width / length ratio, the effect of preventing the turbulence disturbance is greater than that of other structures.
Furthermore, since the present invention has a simple structure in which the linear guide is simply fixed from the upper bracket to the lower floor surface, it is not only easy to manufacture and attach, but also can be manufactured at low cost.

Hereinafter, an example of a roll screen with a guide according to the present invention will be described with reference to the drawings.
FIG. 1 is a partially sectional front view showing a mounted state of a roll screen with a guide, FIG. 2A is an explanatory view when a winding shaft is mounted using a bracket, and FIG. 1B is a winding shaft using a bracket. FIG. 3 is an explanatory view showing the relationship between the bottom member fixed to the lower end of the sunshade member and the linear guide, and FIG. 4 is an explanatory view showing fixing means for the end of the linear guide.

A bracket 3 is attached to the installation surface of the window frame 1 via fixing members 2 and 2. The bracket 3 includes a fixing surface 3 a supported by the fixing members 2 and 2, and side frames 3 b and 3 b that rotatably support both ends of the winding shaft 5 of the awning member 4. The bottom member 6 is fixed to the lower end of the narrow sheet-shaped awning member 4 whose upper end is fixed to the bottom. Pins 9 and 9 are provided on both sides of one side of the inner surface of the bracket 3, and springs 8 and 8 are attached to the pins 9 and 9 so as to be extendable and retractable.
Each linear guide 7 is made of a material that does not damage the surface even when it comes into contact with the awning member 4 such as a metal wire or a synthetic resin string, and reaches the floor surface 11 through a guide roller 10 provided on the other inner side of the bracket 3. It is formed with a length.

  The ends of the linear guides 7 suspended from the bracket 3 pass through through holes 6a and 6a drilled at both ends of the bottom member 6, and are detachably fixed to the floor surface 11 using a surface fastener 12 as a fixing member. It is like that. Reference numeral 16 denotes an operation string provided on the bottom member 6.

The sunshade member 4 of the present embodiment configured as described above is guided up and down by the linear guides 7 and 7 penetrating up and down the left and right sides, so that there is a problem such as a bamboo sword-like turbulence or kinking that is likely to occur during winding. Can be effectively prevented.
Further, the linear guides 7 and 7 are subjected to the lifting load of the awning member 4, but since the appropriate tension is applied to the linear guides 7 and 7 by the traction force of the spring 8, this is allowed and added. Since the guide rollers 10 and 10 provided on the bracket 3 perform fine adjustment movement, the ascending / descending operation of the awning member 4 can be performed stably for a long period of time.

Further, the bracket 3 of the present embodiment in which the springs 8 and 8 and the guide rollers 10 and 10 are arranged on both inner sides of the bracket 3 only changes its direction as shown in FIGS. 2 (a) and 2 (b). Thus, it can be directly attached to either the side portion or the upper portion of the window frame 1.

FIG. 4 shows a specific example of a fixing member that fixes the lower end of the linear guide 7 to the floor surface 11. Of these, FIG. 4A uses the surface fastener 12 as a fixing member as described above, and is the simplest structure in which the linear guide 7 can be attached and detached. As shown in FIG. 4 (b), the fixing member may have a structure in which both linear guides 7 and 7 are fixed integrally with a plate material 14 fixed to the floor surface 11, or as shown in FIG. 4 (c). In addition, a hook 15 may be fixed to the end of each linear guide 7 to engage with the ring 16 of the floor surface 11.

It is a partial cross section front view of the attachment state of the roll screen with a guide which shows one Example of this invention. (A) is explanatory drawing of the state which attached the winding shaft to the ceiling using the bracket, (b) is explanatory drawing explanatory drawing of the state which attached the winding shaft to the front using the bracket. It is explanatory drawing which shows the relationship between the bottom member fixed to the lower end of the sunshade member, and a linear guide. It is explanatory drawing of the Example of the fixing means of the terminal of a linear guide.
