Description

[Detailed description of the invention] Industrial field of application This invention relates to a small window lock for pulling and pressing a small movable shoji in a small window.

Prior art A small window is mainly used for ventilation, but a middle stile is passed over the top of the shoji, and a vertical frame is erected between the middle stile and the upper stile of the shoji, and the left and right vertical stile of the shoji are Together with the upper part, it forms a small window frame, and one side of the vertical frame is often used as a fitting part, and the other side is used as an opening with a small movable shoji screen installed.

The opening of such a small window requires high airtightness and watertightness just like the shoji of the main body, so a tight material facing the indoor side is attached to the inner circumference of the opening of the small window frame. When the movable small window shoji is closed, the small window lock is used to draw the shoji (the action of pressing the main shoji toward the vertical stile side) and to push it toward the outside of the room, ensuring that the small movable shoji is closed, and then Various configurations have been proposed for crimping onto tight materials, such as those described in Japanese Utility Model Publication No. 58-1570 and Japanese Utility Model Application Publication No. 58-85062.

However, the conventional small window lock has a drawing member (in the first publication, the surface 17b of the locking piece 17, in the second publication, the inclined surface 1 of the crimp piece 10).
2) is a so-called wedge-shaped type that comes into contact with the indoor corner of the mating side end face of the movable small window shoji and exerts a drawing force, so the corner may be damaged during drawing. , the draw member may wear out prematurely and become useless. In addition, the slanted surface of the wedge touches the indoor corner of the movable shoji of the small window, making it difficult to draw, and the vibration may cause the draw to become loose. There are some drawbacks.

Problems that the invention aims to solve: This invention can reliably draw and press the small movable shoji to the outdoor side, do not damage the indoor corner of the small movable shoji on the mating side, and is lightweight. The challenge is to provide a small window lock that can be operated.

Means for Solving the Problem A small window lock is constructed from a base body attached to the horizontal member of the joining part of the small window and a lever attached by a vertical shaft to a lever insertion part provided on the base body.

The lever is rotatable between a locked position and an unlocked position, and the outdoor end of the lever is configured to appear and retract in the moving path of the small window movable shoji, and has a draw part;
A pressing portion is formed, and the indoor end portion is formed as an operating portion.

When the lever is in the lock position, the drawing part and the pressing part of the outdoor side tip part engage with the matching side end surface of the small movable shoji, and the pressing part engages with the matching side end surface of the shoji. It will be placed in contact with the expected interior surface.

The base body is provided with a return prevention stopper that prevents the lever in the locked position from returning to the unlocked position.

Function: When the lever is horizontally rotated to the locked position, the drawing part presses the mating side facing surface of the movable small window shoji in the closed position toward the vertical stile side of the main shoji.

When the lever is horizontally rotated to the locked position, the pressing portion presses the indoor side surface of the movable small window shoji in the closed position on the mating side toward the outdoor side.

The backlash prevention stopper holds the lever in the locked position and prevents it from loosening in the pulled state and preventing the small window movable shoji from being opened unexpectedly.

The projecting piece-like drawing part 48 has a contact surface 52 that projects in the indoor and outdoor directions when the lever 29 is in the locked position as shown in FIG. The movable glass 18 side of the movable glass 18 is substantially parallel to the indoor side surface of the glass 18 with respect to the contact surface 52 of the movable glass 18 . Note that reference numeral 53 is an adjustment protrusion that is selectively attached to the pressing portion 50. When this is utilized, the top surface of this protrusion 53 becomes the aforementioned pressing surface 49.

The outdoor end portion 47 having the drawing portion 48 and the pressing portion 50 is located at the unlocked position where the lever 29 contacts the unlocked position regulating wall 36 when the lever 29 is attached to the lever mounting portion 31 by the shaft 45. (Fig. 1A), when the movable glass 18 is evacuated from the movement path m (having a width corresponding to the thickness of the glass) and is in the locked position in contact with the locking position regulating wall 35 (Fig. 1Ro). ) protrudes into said travel path,
In other words, the drawing part 48 and the pressing part 50 are arranged to move in and out of the moving path of the movable glass 18 as the lever 29 rotates. In this sense, the pressing part 50 with the pressing surface 49 resembles a horizontally rotating cam.

The coil spring 46 is fitted into the upper large diameter part of the hole provided in the lever 29 through which the vertical shaft 45 is inserted, and is compressed between it and the upper inner surface of the lever insertion part 33. , the lever 29 attached to the lever mounting portion 31 is always urged downward.

As shown in FIGS. 3 and 4, the small window lock 15 configured in this manner has a locking protrusion 34 on the outdoor side surface of the rising wall 27 of the stile 7 at a position opposite to the vertical rib 12 of the mating part. Engage and temporarily fix the cover 3.
It can be attached to the small window 4 by opening the slot 0 and screwing screws into the interior side of the frame 7 through the long holes 39 and 39 and fixing them. When the cover 30 is closed, the screws mentioned above are hidden. In addition, in Figure 4, the matching vertical bone 1
The display of two parts is omitted.

When opening the opening 14 of the small window 4, move the lever 29 to the right unlocked position as shown in FIG. 8A. Then, the drawing part 48 and the pressing part 50 on the outdoor side tip part 47 of the lever 29 are pressed against the movable glass 1.
8, the movable glass 18 can be moved toward the fitting portion 13 to open the opening 14. At this time, the lever 29 is in the unlocked position because the lower surface of the protrusion-shaped drawing part 48, which has moved to the opposite side and is retracted, has moved inwards the room beyond the top surface of the small protrusion 38. (FIG. 1A), it is lightly maintained by the small protrusion 38,
The lever 29 moves freely due to vibration, etc., and the movable glass 18
The drawing part 48 and the pressing part 50 do not come into contact with the glass surface during movement.

After closing the opening 14 with the movable glass 18, when locking it, the operating lever 29 is rotated from the unlocked position shown in FIG. 8A to the locked position shown in FIG. 8B. Then, the lever 29 that has been rotated fits into the groove-shaped backlash prevention stopper 37 provided on the locked position side of the opening 33 and stops, but before that, the lever 29 is stopped by the protruding piece-shaped drawing part 48 of the outdoor side tip 47. and the pressing part 50 is movable glass 18
The projecting piece-shaped drawing part 4
The contact surface 52 of the movable glass 18 engages with the mating side facing surface of the movable glass 18 and pushes it toward the auxiliary stile 11 (drawing), and at the same time, the pressing surface 4 of the pressing portion 50
9 presses the indoor side surface of the mating side of the glass 18 toward the outdoor side. Therefore, the front facing surface of the movable glass 18 in the closing direction is pressed against the inclined surface 23 of the wedge body 24 of the auxiliary vertical stile 11, which is the door stop side.
Further, the indoor side surface on the mating side is pushed toward the outdoor side, and the outdoor side surface of the movable glass 18 is pressed against the indoor side of the opening tight member 26 attached to the opening 14 closer to the outdoor side. As a result, the opening 14 is airtight and watertight. Furthermore, when the lever 29 reaches the locked position, it is pushed by the coil spring 46 and clicks into the groove of the anti-return stopper 37, so the operator can clearly recognize that the lever has reached the locked position. .

On the other hand, in this state, the protrusion-like drawing portion 48 is engaged with the mating side facing surface of the movable glass 18, and the lever 29 is urged downward by the coil spring 46, and the operating portion 51 is pressed downward. Since it is not possible to escape from the above-mentioned return prevention stopper 37 unless it is lifted upward, the locked state for the movable glass 18 is ensured.

Movable glass 1 as shown by broken lines in Figure 1 A and B.
If the thickness of the pressing surface 49 is large, the adjustment projection 53 on the pressing part 50 may be replaced with one with a smaller head thickness, or the adjustment projection 53 may be removed.
Adjust the position.

In the case of the above embodiment, the vertical shaft 45 may be provided on the lever 29 side, and even if the coil spring 46 is not provided, there will be no particular hindrance to locking and unlocking using the lever. is not required.

The return prevention stopper 37 at the lower edge of the opening 33 may have a shape other than a groove, and may also be provided at the upper edge of the opening 33. However, if a backstop stopper 37 is provided at the upper edge of the opening, a spring is required to bias the lever 29 upward.

Effects of the invention: The rotation direction of the lever is horizontal, and the pulling force from the drawing part at the tip on the outdoor side acts on the facing surface of the movable shoji window on the joining side along the direction of movement of the movable shoji. Therefore, unlike the conventional wedge-type lock, the corner of the end face of the movable small window shoji on the joining side does not dig into the inclined surface, and the operation of the lever is easy. In addition, the facing side of the movable shoji window, including the indoor corner, is not damaged.

The return prevention stopper ensures that the movable small window shoji is kept in the closed position and locked.
