Description

[Detailed description of the invention] [Industrial application field] This invention is used to open and close light-shielding materials such as blinds and curtains attached to the inside of a transparent plate such as a glass plate in a double-glazed door, etc. This invention relates to a light-shielding material opening/closing device built into a shoji door.

[Conventional technology]

BACKGROUND ART Recently, in double-glazed doors, blinds or curtains are often attached to the inside of the double-paned glass so that they can be opened and closed. Along with this, various devices for opening and closing blinds and curtains of this type have been devised.

Conventionally, in this type of device, a concave portion opening toward the indoor side is formed in one of the vertical frames constituting the shoji door, and the device moves in the direction of separation using a spring force inside the concave portion, and approaches in the direction of movement using a pair of upper and lower sliders. In addition to providing a slidable adjustment box with a pair of stoppers that move,
Connect the upper and lower cables for opening and closing the blind to this adjustment box, and by grasping the pair of sliders with your fingers and applying strong force to move the pair of stoppers closer together, the concave part and the pair of stoppers will separate and adjust. The box can be moved up and down along the recess, and when you release your fingers from the pair of sliders, the pair of stoppers moves in the direction of separation due to spring force and presses against the recess, adjusting the box so that it does not move under the weight of the blind. A device (see Utility Model Publication No. 54-14698) that holds the shoji door in a recess, a pair of lug gears are fixed to the recess formed in one of the vertical frames constituting the shoji door, and an adjustment box to which the upper and lower cables are connected. , a pair of pinions, a slider that locks the pinion, and a spring that holds the slider in a position where the pinion is locked. Normally, the slider locks the pinion and the meshing part of the rack gear locks the pinion. There is a device in which the adjustment box is held so that it does not move upward due to the weight of the blind, and by pushing the slider against a spring, the pinion can be rotated and the adjustment box can be moved up and down (Jikkosho). 54−
(See Publication No. 14699).

[Problem that the invention attempts to solve]

However, since the former device holds the blind by the frictional force between the stopper and the recess, the holding force is weak and the blind may fall due to vibrations when opening and closing the shoji door.

On the other hand, with the latter device, the holding force is slightly larger because the pinion and the rack gear engage to hold the pinion, but since the pinion is locked by pressing the slider against the pinion with a spring force, the locking force of the pinion by the slider is Since the holding force cannot be made strong enough, the blind can be lowered due to vibrations, etc., as described above.

In addition, in both cases, the holding force can be increased by increasing the spring force, but in this case, a large force is required to move the slider against the spring force, resulting in significantly poor operability. Become.

This invention was proposed to solve the above-mentioned conventional problems, and it is possible to securely fix light-shielding materials such as blinds and curtains in any position, and also allows the light-shielding materials to be raised and lowered (opened and closed). ) It is an object of the present invention to provide an opening/closing device for a light-shielding material built into a shoji door, which can perform this operation extremely smoothly.

[Means for solving problems]

In this device for opening and closing light-shielding materials, the stile of a shoji door that incorporates light-shielding materials such as blinds and curtains so that they can be opened and closed is provided with grooves that continue in the longitudinal direction, and the slider can be moved freely in these grooves. In the opening/closing device for a light-shielding material, in which one end of the cable is connected to the slider and the other end of the cable is connected to the light-shielding material, a plurality of locking holes are provided inside the groove. are provided at intervals in the longitudinal direction of the grooves, and the slider is provided with a locking body and an operating body, respectively, and the locking body has a locking claw at the tip of the locking body that engages with the locking hole. The operating body is rotatably attached to the slider in a biased state so that the operating body can be rotated, and the locking body is attached to the back surface of the operating body. A cam slope is provided that contacts the head provided on the opposite side of the locking pawl, and by turning the operating body, the head of the locking body comes into contact with the cam slope, and the head moves into the recess. The locking pawl is pressed against the groove so that it comes off from the locking hole.

〔Example〕

Below, this invention will be explained with reference to an embodiment shown in the drawings. A blind A consisting of a plurality of slats 2, ... and cables 3 is provided inside the double glass of a double glass door 1, and can be opened and closed freely. freely).

Further, in one vertical stile 4 of the double glass door 1, a concave groove 5 having a substantially lip groove-shaped cross section and opening toward the indoor side is formed continuously in the vertical direction. The bottom surface of the concave groove 5 has a locking hole 6, which forms a plurality of locking recesses,...
... are formed at regular intervals in the vertical direction of the groove 5.

Furthermore, a slider 7 is fitted into the groove 5 so as to be vertically movable along the groove 5.
One end of the cable 3 is connected to the cable 3, and the other end is connected to a blind A which is a light shielding material.

When the slider 7 is moved up and down, the blind A can be moved up and down accordingly.

A groove 8 is formed in the slider 7, and a locking body 9 is mounted in the groove 8 so as to be swingable about a horizontal pin 10. A locking hole 6 is provided at the tip of the locking body 9.
A locking pawl 11 that can be engaged with the locking hole 6, . is formed.

Further, a compression spring 13 is attached to the base end of the locking body 9, and the function of the compression spring 13 causes the locking body 9 to be always held in the direction in which the locking pawl 11 presses against the bottom surface of the groove 5. Forced. When the slider 7 moves up and down and the locking pawl 11 and the locking hole 6 match, the locking pawl 11 fits into the locking hole 6, and as a result, the slider 7 moves up and down at that point. The structure is such that it can be fixed.

Further, a shaft portion 14 is provided in a protruding manner approximately at the center of the slider 7 in correspondence with the open end of the groove 5 . A circular operating body 15 is attached to the shaft portion 14 with a snap spring 16.
The locking member 9 is rotatably mounted, and its back surface is in contact with the head 12 of the locking member 9.

A cam slope 17 inclined in the circumferential direction is formed on the back surface of the operating body 15 and comes into contact with a head 12 provided on the opposite side of the locking pawl 11 of the locking body 9.

By turning the operating body 15 in one direction, the highest position 17a of the cam slope 17 and the head 12 of the locking body 9 come into contact and push the head 12.

By forming tapers 11a and 6a on the lower edge, the slider 7 can be securely fixed so that it does not move upward, while it can be locked downward (in the direction in which the blind A opens) by turning the operating body 15. The claw 11 can be moved without removing it.

Furthermore, in FIG. 8, instead of forming the locking hole 6 directly at the bottom of the groove 5, a locking rail 25 having an unevenness 24 forming a locking recess on the side surface is installed in the groove 5.
You can build it inside. Although the embodiment has been described as a blind opening/closing device, the structure is almost the same as a curtain opening/closing device.

[Effect of idea]

This invention has the following effects with the above configuration.

The slider can be fixed and released by simply turning the operating body, making it extremely easy to operate and lifting (opening and closing) light blocking materials such as blinds and curtains.
is easy.

Further, since the locking pawl and the locking hole are held by the cam slope, the slider can be securely fixed.

Therefore, unless the operating body is turned, the slider does not move at all, so there is no risk of the light shielding material such as a blind being accidentally closed due to vibration while the shoji door is being opened or closed.

The locking strength of the slider can be easily increased by paying attention to the shape of the locking pawl.
