Description

[Detailed Description of the Invention] The present invention relates to a shoji pulling tool used for pulling sliding shoji etc. toward the indoor side.

This type of shoji pulling tool is used at the upper and lower ends of the connecting stile of indoor shoji in order to pull the entire shoji, which are connected to each other using a sliding lock or crescent swing, toward the indoor side. The crescent locks are connected to each other so that they operate in conjunction with the rotation of the crescent lock.

By the way, there are various conventional shoji pulling tools, but all of them have the following drawbacks.

In other words, (1) With the type of shoji in which a cam surface is provided at the tip of the actuating piece and the cam surface is pressed against the tip of the rail, when the separation of the shoji is adjusted, the engagement relationship between the tip of the actuating piece and the tip of the rail changes, causing Since the amount of gathering differs, there is a drawback that a predetermined airtight effect cannot be obtained depending on the amount of gathering.

@ The lever has an elongated hole diagonal to the sliding direction of the actuating piece, and a pin provided on the actuating piece is loosely fitted into this hole, so that the lever tilts using the elongated hole as a guide. , the sliding direction of the actuating piece during the pulling operation is determined.

Moreover, the sliding direction of the actuating piece during the pulling operation was chosen because it is possible to make the sliding of the actuating piece lighter when the pin on the actuating piece moves away from the pivot point of the lever than when it approaches it. The interlocking mechanism between the pulling tools and the crescent locks attached to the upper and lower ends of the solid frames of the shoji shoji is complicated as it is necessary to move the operating pieces of the upper and lower shoji pulling tools towards the center of the solid frames, and the mechanism must also be accommodated. There is a drawback that the width of the solid frame has to be increased.

6 A guide piece is provided on the lever that extends through the pivot point to the opposite side of the tip side and is inclined in the direction of rotation, and the guide piece is loosely fitted between the left and right pins provided on the actuating piece, and the pin is Even a type in which the lever is tilted as a guide has the same function and effect as the above-mentioned one, and has the same drawbacks.

The present invention was devised to solve the above-mentioned conventional problems, and its purpose is that the sliding direction of the actuating piece during the pulling operation is not limited, so that the upper and lower actuating pieces can be slid in the same direction with the same force. To provide a simple shoji pulling tool which allows the shoji to be pulled even when the shoji is moved, has an interlocking mechanism with a rectangular lock, etc., and requires a relatively small frame width.

Hereinafter, the present invention will be explained with reference to an illustrated embodiment. The distal end of the mounting case 1, which has a groove-shaped cross section, has a pivot point located between the point of force and the point of application, which extends to the opposite side of the distal end through a pivot point that acts as a fulcrum. A lever 2 is attached by a pivot pin 3.

This lever 2 has a first engaging part 4 on the rear end side via its pivot point, which serves as a point of effort when the lever slides, and a pulling part 15, which serves as a point of action when the lever slides, on its most distal end. Furthermore, the pulling part 15
A second retaining portion 5 is provided between the pivot point and the pivot point.

The first retaining part 4 is the bottom side of the mounting case at the rear end of the lever when the rear end of the lever is formed into a frame that opens at least toward the bottom of the mounting case, and the second retaining part 5 is the end of the lever. When the part has a groove-shaped cross section that opens on the bottom side of the mounting case, it is a protrusion that is pressed out on the inner surface of both side walls.
Further, the tip of the lever comes into contact with the upper guide rail when the lever slides, and serves as a pulling portion 15 that pulls the upper stile toward the indoor side.

On the other hand, an actuating piece 6 having a groove-shaped cross section is installed in the mounting case 1 so as to be slidably guided by a guide (not shown).

This actuating piece 6 has a first cam surface 7 that hits the first retaining part 4 and tilts the lever 2 when sliding, and a second cam that hits the second retaining part 5 and stops the lever 2 from tilting. It has a surface 8.

The first cam surface 7 is the side edge of an isosceles trapezoidal projection 9 that is connected to the side edge of the side wall of the actuating piece 6, and the second cam surface 8 includes a chamfered portion of the side wall at the tip of the actuating piece. It is said to be a lateral edge.

In the interlocking mechanism with the crescent lock, in the upper shoji pulling tool, the first cam surface 7 is positioned above the first retaining section 4 while the second cam surface 8 is in contact with the second retaining section 5. In addition, in the lower shoji pulling tool, the first cam surface 7 is
The lower shoji is located at the upper stage of the retaining part 4, and the position of the first cam surface 7 is different so that the first cam surface 7 comes into contact with the first engaging part 4 by sliding in the same amount and in the same direction, and the lower shoji In the pulling tool, operating pieces 6, 6 may be used which have a recess (not shown) in the upper stage of the second cam surface 8 into which the second retaining part 5 enters when the lever is tilted.

In this embodiment, the first engaging part 4 was located at the bottom side of the mounting case at the rear end of the rear end of the lever forming the frame, but as shown in FIG. Slanted side part 10
Further, an adjustment block 11 is mounted inside the rear end of the lever so as to be able to swing freely and laterally move by means of a pin 3, and the adjustment block 11 contacts the bottom side of the mounting case at the rear end from the bottom side of the mounting case.
A protrusion 13 is further provided on the bottom side of the mounting case of the adjustment block 11 so that the screw 12 can be used for lateral movement. The inclined portion of the isosceles trapezoidal protrusion 14 may be used as the first cam surface 7.

In this case, there is an advantage that the degree of protrusion of the first retaining part 4 of the lever 2 can be adjusted by adjusting the position of the adjustment block 11 that abuts the inclined part 10, and thereby the degree of tilting of the lever 2 can be adjusted.

According to the present invention, when the actuating piece is tilted, the first cam surface hits the first retaining portion of the lever to tilt the lever, and the second cam surface hits the second retaining portion of the lever and stops the lever from tilting.
Since it has a cam surface, if you prepare an actuating piece with a first cam surface in a different position, you can tilt the lever with the same force even if you change the sliding direction. The direction in which the actuating piece slides during operation is not limited, and therefore we have adopted a type that allows the upper and lower actuating pieces to slide in the same direction as an interlocking mechanism with a crescent lock etc. The width of the frame can be made relatively smaller than before.

Furthermore, by changing the length of the pulling part, the distance between the fulcrum (pivotal point) and the point of action (pulling part) can be adjusted, and the sliding part of the pulling part can be adjusted as desired. It can be attached to any type of rigid frame and can be reliably pulled in with light operation.
