Description

[Detailed Description of the Invention] This invention relates to a slide lock that can be used for adjusting the opening/closing angle of a swingably supported louver.

A plurality of louvers are arranged in parallel in the vertical direction in the opening inside the shoji or the opening in the window frame, and the center part of the arm attached to both ends of each louver is swingably supported, and each end of this arm is Louver devices have conventionally existed that are connected to interlocking links and move the interlocking links longitudinally to open and close the louvers at the same time.

The means for lifting and lowering the interlocking link is a handle type in which the rotation of a rotatably supported handle is converted into the vertical movement of a rack supported so as to be able to rise and fall, and this rack and the interlocking link are connected by a link. or a pulley rotating type in which a rotatably supported pulley is rotated by the movement of an endless chain attached to it, and the rotation is used to move an interlocking link by a mechanism similar to the above. However, each operating means has a problem in that the dimensions from the manual operating section to the interlocking link are large, and installation is often restricted.

Therefore, the object of this invention is to solve the above-mentioned drawbacks, to provide a slide lock that is not subject to any restrictions on installation, can be installed with good appearance, and is easy to operate.

The configuration of this invention will be explained below based on the attached drawings.

As shown in the figure, a case will now be described in which the slide lock according to the present invention is used for adjusting the opening/closing angle of a louver in a louver device.

Here, in the louver device, a plurality of louvers 2 are arranged vertically in parallel inside a window frame 1, and the central part of an arm 2 attached to the end of each louver 2 is fixed with a pin 4 in the vertical direction of the window frame 1. It is connected to the frame 5, and the end of the arm 3 is connected to an interlocking link 6 arranged inside the vertical frame 5, and by moving the link 6 up and down, each louver 2 is made to swing at the same time. It is set as.

An opening 7 is formed in the front plate 5' of the vertical stile 5, and a lock box 10 is inserted into this opening 7. The lock box 10 has a button support plate 12 attached to the front side of the case body 11, and both ends of the plate 12 are screwed to the top and bottom of the opening 7 of the vertical stile 5, so that the case body 11 is secured inside the vertical stile 5. It is located in

Inside the case body 11 is a vertically elongated guide space 13.
is formed, and this guide space 1 is opened from the front of the lock box 10.
Two button insertion holes 14, 14 communicating with the button 3 are provided. Push buttons 15 and 16 are slidably and tiltably inserted into each button insertion hole 14, and each of these buttons 15 and 16 is pressed outward by a spring 17 to engage an engagement piece 18 provided halfway around the outer circumference. is in contact with an inward flange 19 provided at the opening edge of the button insertion hole 14.

The pushbuttons 15 and 16 each include a button shaft 20, and the tip of each button shaft 20 is located in a small diameter hole 21 formed at the tip of the button insertion hole 14.
The lower side of the button 15 is brought into contact with a part of the tapered surface 20 formed at the lower inner circumference of the small diameter hole 21 by the elasticity of the spring 17 that presses the button 15. On the other hand, the upper side of the button shaft 20 of the lower push button 16 is in contact with a part of the tapered surface 22 provided on the upper inner circumference of the small diameter hole 21.

A downwardly inclined inclined surface 23 is provided above the tip of the button shaft 20 of the upper push button 15, and a guide surface 24 inclined in the same direction as the inclined surface 23 is provided on the back side of the tip of this inclined surface 23.
is provided.

On the other hand, the button shaft 20 of the lower push button 16
At the bottom of the tip, there is an inclined surface 2 that slopes upward.
3', and a guide surface 24' inclined in the same direction as the inclined surface 23' is provided on the back side of the tip of the inclined surface 23'.

A slider 25 is provided in the guide space 13 of the case body 11 so as to be movable up and down.
The connecting pin 26 provided on the side surface of the guide space 13
It is inserted into a vertically elongated hole 27 formed in the side wall of the link 6 and protrudes outward, and its protruding end is inserted into a horizontally elongated hole 8 formed at the lower end of the interlocking link 6.

On the front surface of the slider 25 corresponding to the push buttons 15 and 16, a plurality of inclined guide holes 28 and 29 are formed at equal intervals in the vertical direction in the upper and lower parts sandwiching the center in the length direction. The inclined guide hole 28 formed in the lower part of the slider 25 is inclined downwardly, while the inclined guide hole 29 formed in the lower part of the slider 25 is inclined upwardly. Horizontal holes 30 are provided at the top and bottom of the back surface of this slider 25,
A ball 31 is placed in the horizontal hole 30, and a spring 32 presses the ball 31 against the back surface of the guide space 13.
is inlaid.

The slider lock of this invention has the above-mentioned structure, and when the plurality of louvers 2 are to be swung in the closing direction, the upper push button 15 is pressed, and when the louvers 2 are to be swung in the opening direction, the lower push button 15 is pressed. Press the push button 16 of the button.

Now, in the state shown in FIG. 1, when the upper push button 15 provided on the upper front surface of the lock box 10 is pressed against the elasticity of the spring 17 and moved in the axial direction, the tip of the button shaft 20 will move downward. In order to enter the inclined guide hole 28, the slider 25 moves upward due to the tilting action of the inclined surface 23 of the button shaft 20, and the lower part of the opening edge of the inclined guide hole 28 is moved to the lower side of the button shaft 20. It moves up a certain stroke until it comes into contact.

The slider 25 is provided with a connecting pin 26, and the tip of the connecting pin 26 is fitted into the horizontally elongated hole 8 of the interlocking link 6, so that the upward movement of the slider 25 causes the interlocking link 6 to move. The arm 3 connected to this rises and swings, causing the louver 2 to rise.
swings in the closing direction.

After pressing the upper push button 15, when this pressing is released, the button 15 moves outward due to the elasticity of the spring 17. At this time, the lower side of the button shaft 20 moves in the axial direction along the lower side of the opening edge of the inclined guide hole 28, and when the guide surface 24 comes into contact with the lower side of the opening edge, the slider 25 is moved by the elastic force of the spring 32. The button shaft 20 is pressed against the front side of the guide space 13 and stopped by frictional contact, while the inclined surface 23 of the button shaft 20 faces the small diameter hole 21 and can move upward. While moving in the direction, it also moves upward,
When the tip passes the opening edge of the inclined guide hole 23, it moves downward by the elasticity of the spring 17, and the tip corresponds to the opening of the next inclined guide hole 28.

Therefore, if you repeatedly press and release the push button 15,
Each time the push button 15 is pressed, the slider 25 moves up by a certain stroke, and in conjunction with this, the louver 2 rotates in the closing direction by a predetermined angle.

Also, when the lower pushbutton 16 is pressed and moved in the axial direction, the button shaft 2 of this button 16
Since the tip of the slider 25 enters the upwardly sloped inclined guide hole 29, the slider 25 rises due to the tilting action of the inclined surface 23', and the lever 2 can be swung in the opening direction.

As shown in FIG. 3, a chevron-shaped engagement protrusion 33 is provided on the front surface of the guide space 13,
On the front surface of the slider 5, chevron-shaped engagement holes 34 into which the engagement protrusions 33 fit are provided at equal intervals in the vertical direction.
5, the engagement protrusion 33 engages the engagement hole 34.
By fitting the slider 25 into the position, the ball 31 and spring 32, which press against the back of the slider 25, can reliably stop the slider 25 at the vertically moved position. When retracting, the slider 25 can be prevented from moving slightly backward due to the inclination of the guide surfaces 24, 24', and reliable operation can be achieved.

Note that the use of the slider lock according to this invention is not limited to louver devices, but can also be used for other devices.

As described above, according to this invention, since the axial movement of the pushbutton is converted into the vertical movement of the slider, the overall size can be reduced, and as a result, there are fewer restrictions on installation. Moreover, the slider can be moved up and down by pressing and releasing the push button, making the operation easy. The slider is pressed against the entire inner circumference of the guide space by the elasticity of the spring, while the push button is provided with a guide surface inclined in the same direction as the above-mentioned inclined surface on the back side corresponding to the tip of the inclined surface. When the surface touches the opening edge of the inclined guide hole and moves, the push button is made to tilt.
When the push button retreats due to the elasticity of the spring, the slider can be prevented from moving in the vertical direction, and when the guide surface passes through the opening edge of the inclined guide hole, the elasticity of the spring that presses the push button prevents the slider from moving up and down. Therefore, the tip of the push button returns to the position corresponding to the opening of the next inclined guide hole, so that the slider can be reliably moved by a constant stroke.
