Description

[Detailed description of the invention] [Field of industrial application] This invention is based on a system in which a plurality of shoji are lined up on the same plane and closed within a frame, and the shoji that abuts the vertical frame is moved in parallel from within the frame. For sashes that are moved to a position where they will not be interfered with by other shojis, and then slid along the rails on a sliding basis, a function has been added to ensure that the shoji is held in the transferred position when the shoji is transferred parallel to the outside of the frame. Concerning a certain Satsushi.

[Conventional technology]

The shoji that opens and closes in this type of satsushi,
An operating rod is provided around the frame four times, and the operating rod is linearly reciprocated by the rotation of a handle provided on the stile, and the shoji is tightened to the frame or other fixed shoji in relation to the operating rod. A mechanism for releasing the shoji and a mechanism for transferring the shoji outside the frame using links that convert the linear reciprocating motion of the operating rod into rotational motion are provided, and by turning the handle of the closed shoji,
First, the tightened state is released, and then the shoji is transported parallel to the outside of the frame via the links.
The shoji transported in this way can slide along the rails, but if the handle is turned by mistake during this sliding, the shoji will move in parallel in the direction of being stored in the frame, and there is a high risk that it will hit another shoji. Therefore, it is necessary to prevent the handle from rotating while the shoji slides along the rail. As a means to solve this problem, it was proposed to lock the operating rod that interlocks with the handle.

[Problem that the invention attempts to solve]

However, since the operating lever is fitted into the frame with consideration given to reducing the sliding resistance, this has the drawback of causing the operating lever to swing in the opposite direction, resulting in a problem that the lock lacks reliability.

This idea aims to solve the above problems,
To provide a sliding sash having a function of allowing the swing of an operating rod and yet ensuring a locking action.

[Means for solving problems]

The solution proposed by this invention is that a plurality of shoji are housed in a frame on the same plane, and the shoji that is in contact with the vertical frame and can be opened and closed is operated by a handle provided on the shoji. The sliding door slides horizontally along the rails after being transported in parallel from within the frame to a position where it will not be interfered with by other shojis, using an operating rod that makes reciprocating linear motion and a shoji transfer mechanism that converts the linear motion into rotational motion. In the sash, a lock lever is installed on the underside of the shoji that opens and closes,
The lock lever is provided along the lateral direction of the shoji, facing the operating rod, and pivoted at the intermediate portion in the longitudinal direction so as to be able to swing up and down, and a roller is provided at the base of the lock lever, a locking portion is provided at the tip, and a spring The base of the lock lever is biased downward and the tip is biased upward, and a block that is fixed to a corner of the frame has an inclined surface that becomes lower toward the sliding direction of the shoji, and the roller is attached to the inclined surface. is formed so as to upwardly press the base of the lock lever by contacting with pressure, and when the shoji is transferred parallel from the frame to the operating rod, a step-shaped convex is formed facing downward and facing the locking part of the lock lever. It is characterized by the provision of provisions.

〔Example〕

To explain this idea in detail, the sliding sash shown in FIG.
The fixed shoji 3 are placed on the right side so as to be closed together on the same plane, and the shoji 2 transferred outside the frame 1 is placed in the corner of the movable shoji 2 on the lower door stop side.
A holding device A is provided for fixing the frame 1 so that it does not move back into the frame 1. This shoji 2 is provided with an operating rod 4 that goes around four times as shown by the dotted line in FIG. The rod 4 is provided with a shoji tightening mechanism B and a shoji transfer mechanism C, and when the shoji 2 is to be transferred, the operating rod 4 is slid in the direction of the arrow in FIG. 1. Moreover, this shoji 2 slides on rails 6 provided on the indoor side of the lower frame 1a via a door roller (not shown).

Therefore, in the holding device A, as shown in FIGS. 2 to 5, a frame 7 is fixed to the corner portion of the lower surface of the shoji 2, and a middle portion of a lock lever 8, which is formed long in the width direction of the shoji 2, is attached to the frame 7. A roller 10 is rotatably mounted on the base of the lock lever 8 on the vertical frame 1b side along the longitudinal direction of the rail 6, and is bent upward at the tip of the lock lever 8 to form a hook shape. A locking portion 11 is provided in the form of a flat plate or a step-shaped notch at the upper end corner of the rectangular plate, and the locking portion 11 is provided below the operating rod 4 so as to face each other; A compression spring 12 is interposed between a part of the lock lever 8 between the pivot 9 and the roller 10 and the frame 7, and the base of the lock lever 8 is biased downward, and the locking part 11 at the tip is biased upward, so that the operating lever is activated. It is pressed against the back side of 4. Moreover, as shown in the figure, the roller 10 is constructed by installing a support shaft 13 on the lock lever 8 perpendicularly to the longitudinal direction of the lock lever 8, and attaching the roller 10 to the outdoor end of the support shaft 13, and using a compression spring 14. The support shaft 13 is biased toward the outdoor side. Further, the block 15 has a length from the position where the shoji 2 is completely housed within the frame 1 until it is completely transferred to the outside of the frame 1.

On the other hand, a block 15 is fixed to the corner between the lower frame 1a and the vertical frame 1b, and an inclined surface 16 is formed on the upper surface of the block 15 so that the movable shoji 2 slides along the rail 6 and faces in the direction in which it opens. When the shoji 2 is in the closed state, the inclined surface 1
The roller 10 is pressed onto the lock lever 6, and in this pressed state, the base of the lock lever 8 is raised and the tip is lowered to hold the locking portion 11 at the tip away from the operating rod 4 below. Therefore, while the shoji 2 is being transferred from the state housed within the frame 1 to the outside of the frame 1, the locking portion 11 is separated from the operating rod 4. However, when the shoji 2 is transferred outside the frame 1 and slides along the rail 6, and the roller 10 is removed from the slope 16 of the block 15, the locking part 11 comes into pressure contact with the operating rod 4. .

On the back side of the operating rod 4, there is a protrusion 1 formed of a plate.
7 is provided to protrude downward, and the protruding strip 17
moves with the sliding of the operating rod 4, and the state shown in FIG. As shown in FIG. 5, when the operating rod 4 is slid and the shoji 2 is completely transferred to the outside of the frame 1, the end of the protrusion 17 on the doorstop side is locked, as shown in FIG. Part 11
The width of the protrusion 17 is wider than the width of the locking part 11. Therefore, when the shoji 2 is completely transferred to the outside of the frame 1, the end surfaces of the locking portions 11 and the protrusions 17 face each other, and from this state the shoji 2 slides along the rails 6 in the direction of opening. At the same time that the roller 10 is removed from the inclined surface 16, the tip of the lock lever 8 is raised by the spring force, and the locking portion 11 engages with the end surface of the protrusion 17 to prevent the operating rod 4 from moving back. It is something.

As described above, when the shoji 2 is opened along the rail 6 and closed again by moving it toward the door stop, the roller 1
0 slides onto the inclined surface 16 of the block 15 and the locking part 11 of the lock lever 8 is lowered, so the locking part 11 comes off the protrusion 17 and is set to allow the operating rod 4 to slide. By moving back, the shoji 2 is housed within the frame 1. During this time, since the roller 10 is in contact with the block 15, it does not cause any trouble to the operating rod 4.

Incidentally, the aforementioned roller 10 may be directly attached to the base of the lock lever 8. However, in that case, the roller 10 needs to be in contact with the block 15 up to the position where the shoji 2 is transferred to the outside of the frame 1.
For this reason, it is necessary to extend the block 15 further toward the indoor side than the lower frame 1a, which is disadvantageous because its protrusion becomes an obstacle when passing.

In addition, a guide groove 18 is provided in the lower frame 1a,
A convex piece 1 that fits into the guide groove 18 on the frame 7 described above
By protruding 9, the guide groove 18 and the protruding piece 19 can more reliably guide the parallel movement of the shoji 2.

[Effect of idea]

With this sliding sash, a lock lever with rollers and locking parts is attached to the bottom surface of the shoji, which is moved parallel to the outside of the frame and then slid along the rails, using a spring to swing freely. A block with a sloped surface on which the roller of the lock lever comes into pressure contact with the frame is provided, and a protrusion that faces the locking part of the lock lever is provided on the operating rod provided on the shoji, and it is inserted into the frame of the shoji. It is advantageous if the actuating rod is so narrow that its sliding resistance is low and smooth. However, when the shoji is opened and closed, it swings laterally, but since the locking part of the lock lever only engages with the end face of the protrusion, even if the operating rod swings inside the stile, the engagement will not come off. , which reliably prevents the return movement of the operating rod, and therefore, when the shoji slides after being transferred outside the frame, the handle is held in a fixed state, so the shoji can be slid open and closed via the handle. Also, the shoji can be reliably maintained in a position outside the frame. In addition, when the shoji is brought closer to the door stop, the locking lever's locking part is lowered securely by the block and is easily removed from the protrusion, so there is no hindrance to the subsequent movement of the shoji into the frame. I never come.
