Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention is a support for a window frame in a horizontal blind in which the slats are supported between support frames and the support frame is movable up and down along the window frame. This relates to the frame mounting structure.

(Prior art) As an example of a blind installed in a support frame,
The blind shown in FIG. 5 has a square support frame 31.
Both ends of the slats 33 of the first blind 32 are rotatably supported, and the first blind 32 is a blind in which only the angle of the slats 33 can be adjusted, and is suspended and supported by the lower frame 31a of the support frame 31. The second blind 34 is connected to the ladder cord 35.
Each slat 36 is supported by
7 allows the slat 36 to be raised and lowered by raising and lowering the bottom rail 38. The support frame 31 of the first blind 32 is the window frame 3
It is possible to move up and down along line 9.

(Problem to be Solved by the Invention) The first blind 32 described above has a structure in which the guide piece 40 protruding to the outside of the support frame 31 is guided so as to be vertically movable relative to the guide groove inside the window frame 39. ,
Due to a dimensional error between the width of the support frame 31 and the distance between the window frames 39, the support frame 31 may wobble in the front-rear direction or the left-right direction.

Structure of the Device (Means for Solving the Problems) In order to solve the above problems, this device uses a biasing means to provide elasticity to one of the support frame 1 and the window frame 11, as shown in FIGS. 1 and 2. A guide roller 12 that is guided and supported is provided, and a guide groove 20 that moves the guide roller 12 is provided on the other side.

(Function) By the above means, the support frame 1 is elastically supported between the guide rollers 12 urged by the urging means.

(Embodiment) An embodiment embodying this invention will be described below with reference to Figs. 1 to 4. The upper and lower two-part blind shown in Fig. 3 has a rectangular frame shape similar to the conventional example. Both ends of the slats 3 of the first blind 2 are rotatably supported on the support frame 1 of the support frame 1, and each slat 5 of the second blind 4 is suspended and supported by a ladder cord 6 from the lower frame 1a of the support frame 1. . The slats 3 and 5 of both blinds 2 and 4 can be adjusted in angle by moving up and down an operating knob 7 provided on one window frame 11, and the slats 5 of the second blind 4 can be adjusted in angle. Each slat 5 can be raised or lowered by operating a lift cord 9 using a grip 8 exposed on the frame 1a to raise or lower the bottom rail 10.

The support frame 1 is movable up and down along the window frame 11 by being guided by a plurality of guide rollers 12 provided vertically at predetermined intervals on the window frame 11 on both sides thereof, but the lower part of the support frame 1 is always moved. It is held in a predetermined position as shown in FIG. 3 by stoppers 13 provided on both sides. The guide structure of the support frame 1 by the guide roller 12 will be explained in detail based on FIGS. 1 and 2. At the mounting position of the guide roller 12 of the window frame 11, there is a mounting hole 14 for mounting the guide roller 12. A substrate 15 is fixed to the mounting hole 14 .

A total of four support shafts 16 are protruded from the base plate 15 at a predetermined interval in the front and back, one pair each on the upper and lower sides, and each pair of upper and lower support shafts 16 has an angular bearing 17 movably in the axial direction. A guide roller 12 made of a ball bearing is rotatably supported between the pair of bearings 17. A coil spring 18 is disposed around each support shaft 16 between a bearing 17 and the substrate 15, and a coil spring 18 is disposed around each support shaft 16.
Due to the biasing force of the coil spring 18 with 5 as the fulcrum, the bearing 17 and the guide roller 12 are moved to the support frame 1.
is biased towards. Note that pins 19 are fitted into the tips of the support shafts 16, respectively, to regulate the movement stroke of the bearings 17.

Guide grooves 20 are provided on both sides of the support frame 1,
The guide roller 12 rotates within the guide groove 20 and moves relative to the guide roller 12 .

Now, when the support frame 1 supported between the window frames 11 with the above structure is moved up and down along the window frames 11 as shown in FIGS. 3 and 4, each guide roller 12 moves along the support frame It moves relative to the support frame 1 while rotating the guide grooves 20 on both sides. and,
Since each guide roller 12 is in pressure contact with the guide groove 20 by the biasing force of the coil spring 18, the support frame 1 is sandwiched between the plurality of guide rollers 12 provided on the window frames 11 on both sides. As a result, both window frames 1 can be fixed without wobbling from front to back and from side to side.
It is moved up and down along 1.

Furthermore, since the guide roller 12 can move slightly in and out of the window frame 11 by expanding and contracting the coil spring 18 that biases the bearing 17, slight dimensional errors in the width of the support frame 1 and the distance between the window frame 11 may occur. This bearing 1
7 and the substrate 15.

In the above embodiment, the guide roller 12 is connected to the window frame 1.
1, and the guide groove 20 of the guide roller 12 is provided on the side surface of the support frame 1; however, the guide roller 12 may be provided on the support frame 1, and the guide groove 20 may be provided on the window frame 11.

(Effects) As detailed above, this invention exhibits an excellent effect in that the support frame 1 that supports the blind can be smoothly moved with respect to the window frame 11 without rattling.
