[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a blind bracket for fixing a blind support frame to a window frame or the like, and more particularly to a blind for fixing a blind support frame by holding the blind support frame in a space formed by the blind bracket. Regarding brackets.
[0002]
[Prior art]
Conventionally, as this type of blind bracket, for example, there is one described in Japanese Utility Model Publication No. 4-31998. In this publication, a top plate and a rear plate integrally formed in an L-shape, a front plate pivotally supported by the front end portion of the top plate, and a bottom plate pivotally supported by the lower end portion of the rear plate are provided. Provided with an engaging locking part for detachably connecting the front side plate and the bottom plate, and the bottom plate is provided in the middle of the direction connecting the pivoting support part and the engaging locking part of the bottom plate. At least one hinge portion is provided. In order to attach the blind support frame to the bracket, the bottom plate is previously placed in a bending posture via the hinge portion, and the blind support frame is temporarily fixed to the bracket. Next, while gradually extending the bottom plate, the bottom plate is swung toward the front side plate and passed between the blind support frame and the uppermost slat of the slat group suspended by the blind support frame. Finally, the bottom plate is made straight near the lower edge of the front plate, and the engagement locking portion of the bottom plate is engaged with the engagement locking portion of the front plate.
[0003]
As described above, the conventional blind bracket has a structure in which the bottom plate is bent by the hinge portion when the bottom plate is rotated to attach the blind support frame to the bracket. Even when it is longer than the distance between the bottom surface of the support frame and the uppermost slat, the bottom plate can be prevented from interfering with the uppermost slat and caught, thereby preventing damage to the slat. Has an effect.
[0004]
[Problems to be solved by the invention]
By the way, in order to prevent light leakage when the slats are rotated and the blinds are fully closed, the uppermost slats are set as close to the bottom surface of the blind support frame as possible, and the blinds are supported when fully closed. It is desirable to minimize the distance formed between the bottom surface of the frame and the uppermost end of the uppermost slat. In response to this requirement, the above-described conventional configuration can be bent even if the distance is shorter than the length of the bottom plate in the rotational direction because the bottom plate can be bent. However, even the conventional configuration is not sufficient when it is desired to further shorten the facing distance between the bottom surface of the blind support frame and the uppermost slat because the slat width of the slat is small.
[0005]
In particular, when the slats are elastic slats such as aluminum slats, when the bottom plate interferes with the slats, the bottom plate can be rotated while bending the slats. In the case of a slat having no elasticity, it is not easy to bend the slat. For this reason, it is necessary to ensure that the trajectory of the bottom plate does not intersect the uppermost slat.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and even if the distance between the blind support frame and the closest slat is small, the blind support frame can be attached without being caught by the closest slat. Its purpose is to provide a bracket.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is an L-shaped bracket main body in which a top plate and a rear side plate are integrally formed, and is rotatably supported at a tip portion of the top plate. The front plate and the bottom plate rotatably supported by the lower end of the rear plate, the front and rear plate of the front plate and the bottom plate can be connected to each other, the bracket body, the front plate and In the blind bracket that forms a space for holding the blind support frame with the bottom plate,
A rotation axis that is a rotation center with respect to the rear plate of the bottom plate is slidable in a long groove formed in the bottom plate or the rear plate, and is movable relative to the bottom plate or the rear plate, Therefore, the length in the rotational direction of the bottom plate protruding from the rear side plate can be shorter than the length in the state where the bottom plate is connected to the front side plate.
[0008]
Conventionally, the rotation length of the bottom plate protruding from the rear side plate is fixed. Therefore, when the bottom plate is rotated with respect to the rear side plate, the rotation trajectory of the bottom plate around the rotation axis is the latest. In order not to cross the contact slats, there was no way to increase the distance between the blind support frame and the closest slats. However, in the present invention, the rotation direction length of the bottom plate protruding from the rear side plate can be shortened by the movement of the rotation shaft. By shortening the rotation direction length while turning the bottom plate, even if the distance between the blind support frame and the nearest slat is small, the turning trajectory of the bottom plate does not intersect the nearest slat. The bottom plate can pass between the blind support frame and the closest slat without interfering with the closest slat, and connect the rotating tip to the rotating tip of the front plate. it can. Thus, the blind support frame can be held in the space formed by the bracket main body, the front side plate, and the bottom plate.
[0009]
It is preferable that the bottom plate can be shortened in the rotation length protruding from the rear side plate in the direction from the rotation center of the rear side plate toward the closest slat. The pivot shaft can be movable in the front-rear direction, the up-down direction, or the front-rear up-down-downward direction with respect to the bottom plate or the rear plate. The bottom plate can also be provided with at least one hinge portion between the pivot shaft and the pivot tip.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
1 and 2 show a blind bracket according to a first embodiment of the present invention. In the figure, reference numeral 10 denotes a blind bracket. The blind bracket 10 can be fixed to a window frame or the like, and an L-shaped bracket body 12 in which a top plate 13 and a rear side plate 14 are integrally formed, and a front side plate 16. And the bottom plate 18.
[0012]
Attachment holes 13a and 14d for attaching to a fixing part such as a window frame with a fixing tool such as a screw are formed in one or both of the top plate 13 and the rear side plate 14 of the L-shaped bracket body 12. In addition, a mounting portion 14a bent in the horizontal front direction is formed from the lower end of the rear side plate 14, and a part of the blind support frame 22 can be mounted on the mounting portion 14a.
[0013]
The front plate 16 is rotatably supported by the top plate 13 by a rotation shaft 15 that is pivotally supported at the tip of the top plate 13. An engaging portion 16b is formed at the lower end portion of the front side plate 16, and a placement portion 16a bent in the horizontal rearward direction is formed from the lower end of the front side plate 16, and a blind support is provided on the placement portion 16a. The frame 22 can be placed.
[0014]
The bottom plate 18 is rotatably supported with respect to the rear plate 14 by a rotation shaft 17 that is pivotally supported on the lower end portion of the rear plate 14. The bottom plate 18 is composed of two parts, a first bottom plate portion 18a and a second bottom plate portion 18b separated in the length direction, and the first bottom plate portion 18a and the second bottom plate portion 18b can be bent at a hinge portion by a shaft 18c. The first bottom plate portion 18a is rotatably supported on the rear side plate 14 by the rotation shaft 17. The center axis of the rotating shaft 17 is not fixed with respect to the rear plate 14, and the long grooves 14 c and 14 c that extend obliquely in the front-rear and vertical directions formed in the flanges 14 b and 14 b formed on both sides of the rear plate 14. It can slide inside. An engaging portion 18d that can be engaged with an engaging portion 16b formed on the front side plate 16 is formed at the tip of the second bottom plate portion 18b. The lengths in the rotational direction of the first bottom plate portion 18a and the second bottom plate portion 18b may be approximately the same.
[0015]
As shown in FIG. 3, the blind 20 fixed to the window frame or the like by the above-described blind bracket 10 has a blind support frame 22 and a shielding material supported by the blind support frame 22, in this case. The shielding material is a group of slats 24 suspended by a ladder cord 26 with respect to the blind support frame 22. The uppermost slat closest to the blind support frame 22 is a slat 24a.
[0016]
In the blind bracket 10 configured as described above, an operation when the blind 20 is attached will be described. The L-shaped bracket body 12 of the blind bracket 10 is fixed in advance to a window frame or the like. Then, the upper edge portion of the blind support frame 22 of the blind 20 is brought into contact with the lower side of the top plate 13 of the bracket body 12 and the blind support frame 22 is placed on the placement portion 14a of the rear plate 14 so that the blind 20 Is temporarily held (FIGS. 4 and 5). At this time, the bottom plate 18 is located on the rear side of the blind support frame 22. The slat 24 of the blind 20 is in a horizontal state that is a fully open state.
[0017]
Then, the first bottom plate portion 18a and the second bottom plate portion 18b of the bottom plate 18 are bent at the hinge portion by the shaft 18c. Next, in a state where the bottom plate 18 is bent, the rotation shaft 17 is slid with respect to the long groove 14c of the rear side plate 14 and moved to the uppermost end of the long groove 14c, and the bottom plate 18 is retracted rearward and upward. (FIG. 1). Thereby, the rotation locus of the shaft 18c having the rotation shaft 17 as the rotation center can be prevented from intersecting with the uppermost slat 24a closest to the blind support frame 22. In this state, when the first bottom plate portion 18a is rotated about the rotation shaft 17, the shaft 18c passes near the edge of the uppermost slat 24a without interfering with the uppermost slat 24a (FIG. 6). Both the first bottom plate portion 18a and the second bottom plate portion 18b pass between the blind support frame 22 and the uppermost slat 24a without interfering with the uppermost slat 24a. The first bottom plate portion 18a and the second bottom plate portion 18b are extended and straightened, the rotation shaft 17 is moved to the foremost lower end of the long groove 14c, and the front plate 16 is rotated about the rotation shaft 15. The mounting portion 16a is placed below the blind support frame 22 (FIG. 7), and the engaging portion 18d of the bottom plate 18 is engaged with the engaging portion 16b of the front side plate 16. Thereby, the blind support frame 22 is held in the space formed by the blind bracket 10, and the fixed state of the blind support frame 22 can be maintained (FIG. 8).
[0018]
Thus, in this embodiment, the rotating shaft 17 of the bottom plate 18 is slidable with respect to the rear plate 14, and the bottom plate 18 is moved backward relative to the rear plate 14. Therefore, even when the distance between the blind support frame 22 and the uppermost slat 24a is small, the bottom plate 18 can pass therethrough without interfering with the uppermost slat 24a. Accordingly, the distance between the blind support frame 22 and the uppermost slat 24a can be reduced, and light leakage can be prevented. Moreover, the workability for attaching the blind 20 can be improved to prevent damage to the slats 24a.
[0019]
FIG. 9 is a blind bracket according to a second embodiment of the present invention. In this embodiment, a long groove 18 f is formed in the first bottom plate portion 18 a of the bottom plate 18, and the long groove 18 f is a rotation shaft whose central axis is fixedly supported by the flanges 14 b and 14 b of the rear side plate 14. 17 is relatively slidable. When the rotation shaft 17 slides in the long groove 18f of the first bottom plate portion 18a of the bottom plate 18, the length in the rotation direction protruding from the rear plate 14 of the bottom plate 18 can be shortened, and the same action as in the first embodiment.・ Effects can be obtained.
[0020]
Further, in the third embodiment and the fourth embodiment shown in FIGS. 10 and 11, the long groove 14c in which the rotation shaft 17 is slidable does not extend in an oblique direction, but extends in the vertical direction and the front-rear direction. Yes. In this case, the rotation shaft 17 moves upward (in the case of FIG. 10) or backward (in the case of FIG. 11), so that the length of the rotation direction protruding from the rear plate 14 of the bottom plate 18 is shortened. The same operations and effects as those of the first embodiment can be obtained. It is also possible to extend the long groove 18f of the second embodiment in the vertical direction and the front-rear direction.
[0021]
Moreover, although it demonstrated by the case where it consisted of the 1st bottom plate part 18a and the 2nd bottom plate part 18b which became able to bend the bottom plate 18, it is not necessarily restricted to this, Even if the bottom plate 18 is an integral product, Since the rotation shaft 17 of the bottom plate 18 is movable with respect to the rear side plate 14, the blind support frame 22 and the uppermost slat 24a are not compared with the case where the rotation shaft is not movable. The interval between them can be reduced. Of course, as described in the embodiment, one or more hinge portions 18c are provided between the rotation shaft 17 and the rotation front end portion of the bottom plate 18, and the hinge portions 18c are connected to each other so as to be bent. The present invention is more effective when the bottom plate 18 is composed of these parts.
[0022]
【The invention's effect】
As described above, according to the present invention, since the rotational direction length of the bottom plate protruding from the rear side plate can be shortened, the rotational direction length can be shortened while the bottom plate is being rotated. By this, even if the distance between the blind support frame and the closest slat is small, the rotation trajectory of the bottom plate can be prevented from intersecting the closest slat, and the blind can be prevented without the bottom plate interfering with the closest slat. Passing between the support frame and the closest slat, the turning tip can be easily connected to the turning tip of the front plate. Thus, workability for blind mounting can be improved, and damage to the slats can be prevented.
