Description

[Detailed description of the invention] This invention involves fixing an engaging piece to the outer window frame of a sliding window or door (hereinafter referred to as a window in this specification), and fixing the engaging piece to the inner window frame. This invention relates to an opening limit fitting used in combination with a crescent lock formed by fixing a crescent lock that can be freely engaged and fixed with a piece.

Conventionally, the opening limit fitting for crescent locks was
For example, the one described in Japanese Utility Model Application Publication No. 51-155299 is known. This device consists of a main body and an engaging piece. The main body is made by first bending one end of a rectangular flat plate at a right angle, then bending it again at a right angle in the original direction to create a vertical narrow opening at the end, and then bending the other end at a right angle in the same way. It is bent again at right angles to the original direction and tapped holes are punched at several locations along the length of the end. Double-sided adhesive tape is attached to the back of the center part. The engagement piece is an L-shaped piece that engages the crescent fastener, and has a round hole for passing a screw.

Attach this to the window sill as follows. First, pass the engagement piece attached to the exterior window sill through the narrow vertical opening, place the main body against the glass surface, and attach the main body to the glass surface using double-sided adhesive tape. Then, the engagement piece is positioned at the correct position for engaging the crescent fastener, and a screw is screwed from the round hole of the engagement piece into the tap hole of the main body to attach the engagement piece to the main body.

By the way, this item is troublesome to put on and take off. That is, when attaching, the main body must be attached to the glass surface while passing the engagement piece through the narrow vertical opening, and then the engagement piece must be attached to the main body by screwing in the screw. Also, if you want to remove it, you have to peel off the double-sided adhesive tape. Moreover, when it is used again, the double-sided adhesive tape must be reapplied.

This device also has problems in terms of strength because the engaging piece is attached to the main body with screws. Even if the position of the engaging piece is adjusted accurately, if it is not, excessive force may be applied when the crescent clamp is engaged, causing deformation or damage somewhere. Sometimes I end up doing something. Particularly, the parts where screws are used are prone to deformation, and if even a part were deformed, it would not only be unsightly, but there was also a risk that the lock could not be locked sufficiently. Furthermore, since screws are used, there is a risk that the screws will gradually loosen over time and eventually fall off.

Next, as a conventional opening limit fitting,
The one described in Publication No.-18218 is also known.
This item is used as an engagement piece to be attached to the outside window frame.
We use specially manufactured products. That is,
The hole for attaching to the outer window frame with a screw is a long hole in the longitudinal direction, and a protruding shaft with a rectangular cross section is attached to the back of the tip. The elongated main body has a keyhole-shaped through hole at one end and an elongated hole in the longitudinal direction at the other end. The protruding shaft of the engaging piece is fitted into the keyhole-shaped through hole. In addition, a screw is passed through the elongated hole on the other end through a hole drilled in another separately manufactured engagement piece, and the engagement piece is fixed with a nut.

This item will be attached to the outside window sill as follows. First, attach the front engagement piece by passing a screw through the elongated hole at the front of the main body and using a nut, and then attaching the rear engagement piece by passing the protruding shaft through the keyhole-shaped hole at the rear. Screw the screws into the outside window sill and attach the whole thing to the outside window sill. At this time,
The positions of the front and rear engaging pieces are adjusted using their respective elongated holes.

Normally, the front engaging piece is used to lock the lock, but when the front engaging piece is not needed, the protruding shaft of the rear engaging piece is inserted into the circular hole of the keyhole-shaped through hole in the main body. Keep it in a folded position and rotate the main body up and down.

It is also troublesome to attach and detach this item to the outside window frame. Furthermore, since screws are used in a larger number of locations, there are also significant inconveniences caused by the use of screws.

Next, as a conventional opening limit fitting,
-126995 publication is also known. In this device, a main body with a cut groove in the longitudinal direction and a flat C-shaped cross section has a hook fitting attached to the engaging piece of the outer window stile, and a front part that engages the crescent fastener of the inner window stile. The engaging pieces are movably attached to each other. The hook and the front engaging piece are each attached to the main body with screws.

It is also troublesome to put on and take off this item. When installing, hook the hook onto the engaging piece of the outer window stile, press the main body against the outer window sill, tighten the screws to fix the main body, and then adjust the position of the front engaging piece. and then tighten the screws to secure it. If you want to remove it, loosen the screw on the hook and then remove it. The disadvantages of using screws are the same as those mentioned in the above two publications.

In the present invention, various drawbacks of the prior art as described above are solved. Further, the opening limit fitting according to the present invention is extremely easy to attach and detach, and does not use any screws or the like, so there are no disadvantages due to the use of screws. It is as follows. That is, a vertical narrow opening is provided at one end through which the tip of the engaging piece attached to the sliding type outer window frame can be passed through, and the end side is slightly raised from the vertical narrow opening. A receiving part provided at the other end with an L-shaped piece and a vertical piece for fixing the crescent clamp attached to the inner window frame and as a locking part for the engagement piece is integrated. This opening limit fitting for a crescent lock is formed by molding and includes several types of fittings with different distances between the vertically narrow opening and the receiving portion.

If you want to attach this item to an outside window sill, do the following after closing the window. In other words, by tilting this opening limiter slightly so that the tip of the engagement piece attached to the outer window sill fits into the vertical narrow opening on the locking part side, simply press the receiving part side against the window glass. good. When locking, turn the crescent lock to engage the receiving portion at the tip of the opening limit fitting.

When the opening limiter is no longer needed, simply close the window, pull the receiving portion slightly toward you, and remove the engagement piece from the vertically narrow opening at the other end.

To explain the embodiment of this project with reference to the drawings, in the figure, 1 is an outer window frame made of wood, iron, or aluminum, and 2 is an inner window frame made of wood, iron, or aluminum, which is sliding with the outer window frame 1. , 3 is an engaging piece fixed to the outer window sill 1, and has a tip part 3b which tapers from a wide base part 3a to a drip stop and is bent into an L-shape. 4 is a crescent fastener fixed to the inner window frame 2, and is rotatable about a pivot 4a.
