Description

[Detailed Description of the Invention] The present invention relates to a device for slidably holding a movable shoji for snow viewing shoji in the guide grooves of left and right vertical stiles.

Generally, a movable shoji for snow viewing shoji is slidably provided between guide grooves of a vertical stile and can be held at any position. The holding force of this movable shoji is obtained by bringing one or two arc-shaped slide leaf springs attached to the prospective surface of the vertical member of the movable shoji into frictional contact with the guide grooves.

By the way, the movable shoji is fitted into the guide groove at the opposing position based on the Kendon method. In this case, since the sliding plate spring on the first insertion side is crushed in the flat direction, the necessary elasticity tends to decrease.
This decrease in elasticity becomes noticeable when the movable shoji is removed several times. As a result, even if there are two sliding leaf springs on the top and bottom, the elasticity is uneven between the top and bottom, making it impossible for the movable shoji to slide smoothly, and the movable shoji does not stop halfway and reaches the bottom. It may fall.

Furthermore, with conventional sliding leaf springs, it is difficult to operate the movable shoji when pulling it up, and on the contrary, it is usually light when pulling it down, and the operating force is not evenly distributed.

The purpose of the present invention is to enable the movable shoji to slide vertically smoothly and reliably, and to equalize the operating force in the raising and lowering directions of the movable shoji.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

First, FIGS. 1 and 2 show an indoor fitting 1 in the form of snow-viewing shoji screens. This indoor fitting 1 combines left and right vertical stiles 2, 3, an upper stile 4, and a lower stile 5 in a rectangular shape, and incorporates a fixed shoji 6 having a muntin 16 in the upper position between them, and also in the lower position. The plate glass 7 is fixed by a gasket 8, and a movable shoji 11 is fitted vertically and slidably between the left and right guide grooves 9 and 10 formed at opposing positions of the vertical frames 2 and 3. be. This movable shoji 11
The left and right sticks 12, 13 and the top and bottom sticks 14, 15 as vertical members are combined in a rectangular shape,
The muntins 17 are fixed inside them. In addition, the above-mentioned fixed shoji 6 and movable shoji 11
Shoji paper 18 and 19 are pasted on one side of the screen, respectively.

The sliding body 20 of the movable shoji for snow viewing shoji according to the present invention is incorporated into the outer surface of the stick 13 as a vertical member of the movable shoji 11, as shown in FIG.

First, the sliding body 20 shown in FIG. 3 is a frame-shaped member formed by bending a single band-shaped plastic plate made of polyamide resin or the like into a substantially parallelogram shape. This frame-shaped sliding body 20 consists of two parallel supporting plates 21 and 22, a sliding plate 23, and a vertical plate 24. Upper support plate 2
1 is inclined downward when viewed from the attachment 13,
The upper end portion has a mounting portion 25 for attaching to the stick 13. Vertical plate 2 along this attachment part 25 and attachment 13
Mounting holes 26 and 27 are formed in the upper end portion of 4, and the sliding body 20 is attached to the stick 1 as a vertical member by means of mounting screws 28 inserted into the mounting holes 26 and 27.
It is attached to the prospective surface of 3.

At this time, the sliding plate 23 connected to the upper support plate 21 fits into the guide groove 10 of one of the vertical frames 3, but there is a spiral shape between the sliding plate 23 and the vertical plate 24. A compressible spring 29 is attached and the sliding plate 23
is in pressure contact with the bottom surface of the guide groove 10. In addition,
The spring 29 fits into protrusions 30 and 31 that are protruded from opposing positions of the sliding plate 23 and the vertical plate 24.

Now, when the movable shoji 11 is fitted between the guide grooves 9 and 10 of the left and right vertical frames 2 and 3, since the spring 29 presses the sliding plate 23 against the bottom surface of the guide groove 10,
Frictional force is generated between the sliding plate 23 and the guide groove 10, so that the movable shoji 11 can be held at any position.

When the movable shoji 11 is pulled up, a force is applied in a direction that crushes the substantially parallelogram-shaped sliding body 20, that is, in a direction in which the sliding plate 23 separates from the bottom surface of the guide groove 10. Therefore, the movable shoji 11 can be pulled up with a light force. Conversely, when the movable shoji 11 is pulled down, force acts in the direction in which the sliding plate 23 comes into contact with the bottom surface of the guide groove 10, so the frictional force between the sliding plate 11 and the guide groove 10 increases.
Therefore, the movable shoji 11 can be pulled down more smoothly with almost the same operating force as when pulling it up, compared to the conventional shoji.

On the other hand, since the upward downward support 22 of the sliding body is interposed and connected between the sliding body 23 and the vertical plate 24, the sliding plate 23 is unnecessarily moved from the bottom of the guide groove 10 when the movable shoji 11 is lowered. It has the function of suppressing pressure contact and maintaining an appropriate frictional force. In addition, in the holding state of the movable shoji 11 after movement, the gravity is involved in the direction in which the sliding plate 23 of the sliding body 20 is pressed against the bottom surface of the guide groove 10, so that the pressing force of the sliding plate 23 against the guide groove 10 is enhanced by its gravity. Therefore, sufficient frictional force necessary to hold the movable shoji 11 can be obtained.

In the above embodiment, the two support plates 21 and 22 are in a parallel state, but they do not need to be parallel as long as they are oriented in the same direction. Further, the support plates 21, 22 and the sliding plate 23 can be bent at the bending position by utilizing the elastic deformation of plastic, but this bending may also be done by a hinge-shaped shaft or the like. Further, although the support plates 21 and 22 described above have almost no elasticity, the support plates 21 and 22 may be constructed of spring plates, in which case the spring 29 can be omitted.

Since the sliding plate 23 is made of a plastic plate, the guide grooves 9 and 10 of the vertical frames 2 and 3 are not damaged, and the sound during sliding is small, which is advantageous. If the metal plate 23 is made of a metal plate, a slider made of plastic or the like is fixed to the metal sliding plate 23, and the slider indirectly slides the slider plate 23 into the guide grooves 9, 10. You may also do so.

According to the present invention, since the frame-shaped sliding body has an upper support plate that slopes downward when viewed from the vertical member side and a lower support plate that slopes upward when viewed from the vertical stile, the movable shoji When pulling up the movable shoji, the sliding plate receives a force that tends to move away from the guide groove, making it easier to pull up the movable shoji, and conversely, when pulling the movable shoji down, the sliding plate receives a force that presses it against the guide groove. As a result, the operating force when pulling down is the same as the operating force when pulling up, and on the other hand, since the lower support plate is interposed and connected between the sliding plate and the vertical plate, the sliding plate is unnecessary. Prevents strong pressure contact with the guide groove. Furthermore, even at any stop position of the movable shoji, the gravity of the movable shoji generates a force that presses the sliding plate against the guide groove, so even if the sliding body is flattened when the movable shoji is inserted, it is sufficient A stable holding force can be obtained over a long period of time.
