Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen mounting bracket.

[0002]

2. Description of the Related Art A screen such as a roll screen is generally used in the same manner as a Venetian blind using a large number of slats. Therefore, a structure in which a head rail is assembled and fixed to a bracket fixed to a window frame is used. However, since the Venetian blind has a structure in which the slats are supported by cords hanging from several places on the headbox, it is generally possible to construct a channel-shaped material with a concave shape above the headbox. On the other hand, since the screen winds the roll cloth around the take-up shaft and unwinds it, it is necessary to extend it to the upper part of the roll shaft (in some cases, to the front part and the rear part), and to use the open lower part for the lower part. Is different. Therefore, as for the structure of the mounting bracket, the same structure cannot be simply diverted between the two, and the head portion is also called by different names from "head rail" and "head box". The configuration of attaching the head rail of the screen to the fixing bracket with one touch and removing it with the one-touch attachment mechanism proposed by the Venetian blind (for example, the actual open Sho 63-116698) is not common.
No., Jitsukai Sho 63-138397, Jitsukaihei 1-7699
No. 5 etc.) cannot be diverted as they are.

A proposal has been made so far that the head rail for a roll screen, which is the object of the present invention, can be attached to and detached from the fixing bracket with one touch.
For example, in Japanese Utility Model Laid-Open No. 61-117894, a fixing bracket can be moved in the front-rear direction by, for example, a metal flat plate type main body having a U-shaped sleeve-shaped holding portion and the U-shaped sleeve-shaped holding portion. Assemble the head rail while combining a supported plastic slider and forming a pair of claws facing outwards on both sides (main body and slider) while normally keeping the longest span with a spring. At times, the slider is elastically fitted into a predetermined assembled state while moving so that these spans are shortened against the spring force. This bracket has a feature that the whole structure is relatively small and the structure itself is relatively simple.

[0004]

[Problems to be Solved by the Invention] However, the proposal for the above-mentioned roll screen is disclosed in Japanese Utility Model Publication No. Sho 61-11789
A closer examination of the invention of No. 4 revealed various unsolved problems.

One of the most typical problems is to attach and detach the head rail to a bracket fixed to a window frame or the like, and in the above proposal, in the above proposal, the rear side of the window frame (the side close to the window side). ) Located toward the window side (the invisible part that is the back side of the headrail from the operator's side), the hook of the headrail must be hooked to the front side, but this must be fitted. This is not always easy, and especially when a person who is not a specialized worker performs the work, it is extremely difficult to fit the part that cannot be seen from the room side.

Further, the work of attaching and removing is a work that cannot be ignored because of replacement and cleaning of the screen, and the work of attaching and removing these screens from the bracket can be realized as simple and easy as possible. It goes without saying that a structure is required.

It is an object of the present invention to provide a bracket for mounting a screen having a structure devised so that the work of mounting and removing the head rail from such a bracket can be easily carried out.

Another object of the present invention is to provide a screen which allows the bracket to be thin and has an excellent appearance after mounting.

Still another object of the present invention is to provide an inexpensive product having a simple bracket structure.

[0010]

In order to achieve the above-mentioned object, the present inventor completely changed the conventional idea for supporting the head rail, and examined a new structure paying attention to the mounting workability. did.

That is, in the conventional head rail support of the screen by the bracket, the head rail is wrapped in the front-rear direction by the pair of inward claws, or conversely, the head rail is inwardly faced by the pair of outward claws. Although it was usual to engage with the engaging portion, in these methods, even if one of the mounting workability and the removal workability can be made easy, it is easy to make both workability easy. It was difficult as usual.

Therefore, the present inventor views the two points supporting the head rail from the side of the bracket, and both sides are on the side where the worker is located (for example, in the case of a bracket fixed to a window frame,
The present invention was accomplished by paying attention to the fact that the workability can be remarkably improved by using the claw facing the indoor side).

Further, when both of the pair of claws of such a bracket face the indoor side as described above, for example, not only the workability is improved, but also the structure which brings about various effects described later is facilitated. I also found that I could adopt it.

The most typical features of the screen mounting bracket of the present invention made from the above viewpoints are as follows.
A bracket that is fixed to a fixed part such as a window frame and supports the head rail of the screen under the fixed part, and is a substantially rectangular flat plate-shaped main body made of a rigid material fixed to the fixed part, and a front and rear part at the bottom of the main body. A slider that is slidable within a certain range in the direction and is supported so that it can be pushed in from the front end side of the main body, and a spring that pushes this slider to the slide limit position on the front side of the main body. , A pair of pawls for hanging the head rail facing the front side are respectively provided, and a locking portion for restraining the forward movement of the head rail suspended by these pawls is further provided on the main body. It is in the place where it is provided.

Such a bracket of the present invention further projects downward (for example, cut and raised) on the flat plate portion of the main body.
A rib is formed, and this rib serves as a locking portion that engages with a stepped portion of the head rail to restrain the head rail from moving forward, and the fixed support portion on one end side of the spring is formed. It can be made more suitable by constructing it so that it also serves as a stopper to prevent the slider from falling off.In addition, the flat plate portion of the main body is provided with a reinforcing rib that protrudes downward, If the tip of the rib is pressed against the top surface of the formed head rail to prevent lateral displacement of the head rail, it is possible to provide a bracket that can exhibit various excellent effects with an extremely simple structure. can get.

[0016]

The present invention will be described below based on the embodiments shown in the drawings.

The drawings show the construction of an embodiment of the present invention. In these drawings, reference numeral 1 denotes a body of a bracket, for example, by pressing a rectangular metal plate, as shown in the drawing. A pair of U-shaped sleeve portions are provided downward from both side edges on one end side (front end side; for example, the indoor side) in the longitudinal direction to form sleeve portions 11 for slidingly holding the slider, which will be described later. On the other end side (rear end side; for example, the window side), a downward flange 1 having a pair of both-sided claws 13 and 13 facing the front side, which is one of the suspension parts for suspending the head rail at two points.
2, 12 are formed. Reference numerals 14 and 14 are holes into which a screw for fixing the bracket body 1 to a fixing portion such as a window frame is loosely fitted.

The bracket main body 1 of this embodiment is provided with a recessed reinforcing rib 15 protruding downward at the center of the flat plate portion. In this embodiment, the tip (lower end) of this rib 15 is further By pressing the top surface of the head rail attached to the bracket, it is possible to restrain the displacement of the head rail in the lateral direction (the direction perpendicular to the front-back direction of the bracket).

Reference numerals 16 and 16 denote a pair of flanges cut and raised downward from the flat plate portion in the vicinity of the sleeve portions 11 and 11 of the bracket body 1. The flanges 16 and 16 of this embodiment will be described below. It has three functions, namely, one-side locking of the slider pressing spring, moving locking of the head rail, and retaining of the slider.

2 is a plastic slider,
The main body is fitted into the sleeves 11 for sliding and embedding, and is slidably supported in the front-rear direction (the left-right direction in FIG. 1B), and in this example, on both sides of the flat plate, Sleeve part 1 of the main body
The left and right engaging portions 21 and 21 which are fitted and slid into the sliders 1 and 11, and the sliders by extending from the left and right engaging portions 21 and 21 to the rear end side and engaging with the cut-and-raised flanges 16 and 16 of the main body. Retaining hooks 22 and 22 for preventing the retaining of the head rail, a pawl 23 formed to be paired with the pawl 13 of the main body so as to face the same front side in order to suspend the head rail at two points, Slope 24 provided for facilitating the work for engaging the engaging portion of the head rail, one end for inserting a slider pressing spring which one end engages with the cut-and-raised flanges 16, 16 of the main body Open holes 25,2
5 and projections 26 for facilitating the operation of pushing the slider 2 against the spring force by an operator.

Reference numeral 3 denotes a slider pressing spring, which is inserted into the hole 25 of the slider 2 and one end of which is engaged with the cut-and-raised flange 16 of the bracket body 1 to move the slider 2 to the front side. To the limit position (given by the engagement of the body flange 16 and the retaining hook 22).

Next, the operation of attaching the head rail of the screen to the bracket having the above structure and fixed to the fixed portion such as the window frame will be described.

In this example, as shown in FIGS. 2 and 3, the head rail 5 has a longitudinal direction of the mold member 52 provided so as to extend along the upper portion and the front portion of the windup pipe 51 of the screen cloth. Side plates (not shown) are fixed to both ends of the side cover, and side covers 53 are further mounted on the exterior.

A mold member 52 forming the main body of the head rail
As shown in the figure, the upper plate 521 has a pair of claws 54 and 55 facing the rear side at the rear end and the front end, respectively. Reference numeral 56 is a recess for engaging the claw 54 at the front end with the claw 23 of the slider 2 of the bracket.

Further, a stepped portion 52 is provided on the upper plate 521 of the mold material.
2 is formed so as to prevent the head rail 5 from coming off when the head rail 5 is attached to the bracket.

First, as shown in FIG. 2, the head rail having the above-described structure is aligned so that the claw 55 at the rear end engages with the claw 13 of the main body 1 of the bracket, and in that state, the front end of the head rail. When the side is raised upward, the claw 54 engages with the inclined surface 24 of the slider 2 and further pushes up the front end side of the head rail, whereby the slider 2 is pushed against the spring force of the spring 3 (to the left in the figure). Then, when the claw 54 has passed over the slope 24, the slider 2 is returned to the initial position by the spring and the claws 54 and 23 are hooked (see FIG. 3).

In the head rail 5 mounted as shown in FIG. 3, the stepped portion 522 of the upper plate of the head rail 5 has the bracket main body 1
Since it engages with the rib 16 of No. 1, it does not slip out to the right in the figure.

As described above, the head rail can be attached to the bracket very easily.

To remove the head rail, the projections 26 of the slider 2 are pushed against the spring 3 to push the claws 54 and 23.
Can be easily removed by removing the engagement of.

[0030]

According to the bracket for mounting a screen of the present invention, since the pair of claws of the bracket for supporting the head rail face toward the front side (for example, the indoor side), this head is attached when the head rail is mounted. By simply pressing the rail forward (toward the window side) against the bracket, the back claw of the bracket and the engaging part of the head rail can be fitted, and the front claw and the engaging part can be fitted. Is
Since it can be easily done by pushing the head rail upward, there is an effect that the work can be performed extremely easily.

Further, by providing the reinforcing ribs also for preventing the bracket from being displaced with respect to the head rail, it is possible to reduce the thickness of the bracket to such an extent that the existence of the bracket is hardly noticed after the mounting, and the appearance of the screen can be improved. .

Further, one cut-and-raised portion is provided to prevent the head rail after attachment, the slider from coming off, the spring from coming off, etc., which is necessary when the pair of claws of the bracket are oriented in the same direction. Since it can be used for both, there is an effect that the structure of the bracket can be made extremely simple, and the usefulness of the bracket of the present invention obtained by combining the above effects is extremely great.
