Description

[Detailed description of the invention] This invention is a sliding shoji sliding shoji or single sliding shoji sliding shoji built into a frame, in which each of the upper and lower sliding shoji sliding rods is connected to a crescent lock provided in the sliding stile. The purpose of this device is to reduce the number of parts, to make it thin and easy to install inside the frame, and to be highly durable and reliable. It is an object of the present invention to provide a shoji pulling rod interlocking device which provides interlocking operation and does not release the pulled state due to vibration.

As is well known, pulling devices such as sliding shoji are often installed especially when the shoji is large, but if the shoji is tightened with a crescent lock, both the top and bottom of the shoji will not be pulled together completely, resulting in poor airtightness. So, at the same time as turning the handle of the crescent lock,
The drawing rods on both the upper and lower sides of the connecting frame provided with the handles are raised and lowered to draw the inner and outer shoji together over their entire length. Conventionally, a crank has been generally used as a device for interlocking the rotational motion of the handle with the upper and lower pulling rods as vertical linear reciprocating motion.
That is, by fixing the handle shaft to the center of the crank and connecting the pulling rods to both ends of the crank, either directly or via levers, the upper part moves upward and the lower part moves downward. The shoji is pulled together, but such a simple structure has the disadvantage that strong vibrations received by the shoji cause the pulling rods to move back, causing the shoji to be released from its drawn state. Therefore, for example, Japanese Utility Model Publication No. 51-51748 discloses a device configured to withstand vibrations and maintain the drawn state. The attracting device for this publication is:
A connecting link 12 is pivotally supported on an operating lever 9 that is rotated by a handle, and a disk-shaped interlocking lever 10 is pivotally supported at an eccentric position at the tip of the connecting link 12, and connecting rods 16 and 18 are located at positions symmetrical to the eccentric position, respectively. It was supported by However, in this device, the parts that operate the crank consist of three parts: the operating lever, the connecting link, and the connecting rod.If these are made of thin-walled materials, the overall shape can be made thin, but there is a problem with durability, and the thick-walled If it is formed into a shape, the strength will be increased, but it will become thicker as a whole, making it difficult to install it inside the stile.

This idea was devised with the above points in mind, and its main parts consist of a frame, a pair of disc-shaped desks operated by a crank, and a pair of levers connected to the upper and lower pull rods. It is characterized by being configured as follows.

Next, to specifically explain the embodiment according to this invention, as shown exploded in FIG. 1 and assembled in FIGS. 2 and 3, a frame 1 consists of a pair of opposing plates 2. , 2 are assembled by installing fixing pins 3, 4, and 5 at the upper, middle, and lower parts, respectively,
It is fitted into the inner space of the connecting frame 23, and the plate 2 on one side is fixed to the mounting surface of the handle 19 of the connecting frame 23. A disc-shaped crank desk 6 is rotatably supported on the inner surface of the plate 2 on the side fixed to the joining frame 23 of the frame 1, and the desk 6 has an angle in the center into which the pivot shaft 20 of the handle 19 fits. A hole 7 is drilled, and a yank pin 8 is provided at an eccentric position of the desk 6 to project toward the plate 2 on the opposite side of the plate 2 supporting the desk 6. In addition, crank desk 6
The mounting position may be below or above the middle fixing pin 4 of the frame 1, but it is preferable to install it between the middle and lower fixing pins 4.5 as shown in the figure.

The upper and lower levers 9 and 10 are connected to the upper and lower pull rods 21 and 22, respectively, and are arranged in an upright manner on the same plane. A guide hole 11 is bored into which the fixing pin 3 engages. Also, lower lever 1
A guide hole 12, which is long in the vertical direction and is engaged with the lower fixing pin 5, is also formed in the lower part of the lower lever 10, and furthermore, a guide hole 12, which is long in the direction perpendicular to the guide hole 12, is bored in the middle part of the lower lever 10, and is long in the direction perpendicular to the guide hole 12. crank pin 8
A horizontally elongated hole 13 is formed to be engaged with.

Next, the interlocking desk 14 that connects the lower end and the upper end of both levers 9 and 10 has a support shaft 1 at the center of the disc.
5 is provided protrudingly, and connecting pins 16, 16 are provided on the opposite surface of the protruding surface of the support shaft 15 at symmetrical positions from the center, respectively.
The interlocking disk 14 is rotatably supported between the upper part of the frame 1 and the middle fixing pins 3 and 4 on the side opposite to the mounting surface of the crank disk 6.

Further, the middle fixing pin 4 of the frame 1 serves as a stopper that determines the upper limit and lower limit of the lower lever 10, and a stopper opposite to the middle fixing pin 4 is provided between the crank disk 6 and the connecting disk 14 of the lower lever 10. 17 was established. Incidentally, recesses 26, 26 may be provided at the upper and lower portions of the retaining edge 26, into which the middle fixing pin 4 is fitted. Further, each of the upper and lower levers 9, 10 is connected to a spacer 18 fitted to the upper and lower fixing pins 3, 5.
The levers 9, 10 are held between the plates 2, 2 of the frame 1, and the intermediate portions of the levers 9, 10 are kept apart by the spacer action of the crank disk 6 and the interlocking disk 14.

This device has the above structure, and its operation is shown in Figures A, B, and C in Figure 4. Figure A shows the shoji in a completely released state, which is called the lower limit state. , and Fig. C shows a state in which the shoji is completely drawn, and this will be referred to as the upper limit state for explanation.
Now, looking at the individual movements of the levers 9 and 10, the lower lever 10 is raised or lowered while moving in the lateral direction due to the relationship between the crank pin 8 and the horizontally elongated hole 13 due to the rotation of the crank desk 6. , and is reliably guided in the vertical direction by the relationship between the guide hole 12 and the lower fixing pin 5, and further rotates the interlocking desk 14. The upper lever 9 moves up and down in accordance with the rotation of the interlocking desk 14, and is reliably guided in the up and down direction by the relationship between the guide hole 11 and the upper fixing pin 3.

Therefore, when the crescent lock is in the lower limit state in Fig. A, the crescent lock is released, and if the handle 19 is turned from this state and the crank desk 6 is rotated in the direction of the arrow 24, the lower lever 10 is lowered and the upper lever is simultaneously moved. 9 rises and slides through the intermediate state shown in Fig. B to the upper limit as shown in Fig. C. Conversely, if the crank desk 6 is rotated in the direction of the arrow 25, it will return to its original lower limit state.

Furthermore, when the upper lever 10 is held at the upper limit in Fig. C, if a force is applied to the upper and lower rails 9 and 10 in the vertical direction due to vibration, the lower lever 10 is moved between the crank desk 6 and the crank. Since the pin 8 is engaged with the horizontally elongated hole 13, when trying to rotate the crank desk 6 from the lower lever 10, it is necessary to apply force in the vertical and lateral directions, but only in the vertical direction. When applying a pressing force of It is intended to hold the following.

As described above, the main components of the shoji pulling rod interlocking device according to this invention are a frame, a pair of desks, and a pair of levers. arranged vertically and rotatably supported, the lower lever is provided by engaging the lower fixing pin of the frame in its guide hole and engaging the crank pin of the crank desk in the horizontally elongated hole of the lower lever, The upper lever is provided by engaging the upper fixing pin of the frame in its guide hole, and the upper and lower levers are further locked to each connecting pin of the interlocking desk.The number of parts is small, and each desk is a lever spacer. Therefore, it can be incorporated into a thin frame for reliable operation, and it can be easily installed in the inner space of a narrow stile. In addition, the upper and lower levers are connected by a pair of desks, and when the levers are moved up and down, they also slide horizontally to move up and down, so it is easy to move the levers up and down using the rotational force from the crank desk. However, even if a vertical movement force is applied from the lever, the crank desk cannot be easily rotated, and therefore, despite the simplified structure, it is difficult to pull the shoji. It reliably maintains its state even when vibrations are applied.

Furthermore, there is a connected desk that connects the upper and lower levers.
The upper and lower limit positions of the lever are provided at a distance from the central fixing pin on the opposite side of the crank desk, and between the crank desk and the connecting desk of the lever that engages with the crank disk, are provided opposite to the central fixing pin. The tog edge is formed so that it can come into contact with the middle fixing pin, and when this lever moves up and down, it moves up and down while swinging sideways in a oscillating manner. It is separated from the fixing pin, reducing the degree of wear on the locking edge.Even if the lever wall thickness is thin, the locking edge is provided on the side of the lever, so even if the lever contacts the middle fixing pin at the upper and lower limits, the lever will remain intact. It does not bend and can perform a strong stopper function. Further, since the side surface of the lever is a stop edge, it can freely correspond to the stroke of movement given by the design of the lever, and there is no need for precise machining.
