Description

[Detailed explanation of the invention] This invention was filed by the inventor in Utility Application No. 53-61130.
This invention relates to an improvement of the sliding window proposed in Japanese Patent Publication No. 54-163542).

The present invention will be described below with reference to illustrated embodiments.

Reference numeral A denotes an opening frame, and the base end of an arm 2 is rotatably attached to the lower frame 1 of the opening frame, and the distal end portion of the arm 2 is rotatably attached to the lower stile 3 of the shoji B. In addition, a hanger roller 5 mounted on a hanging shaft 4 erected on the upper stile 3' on one end side of the shoji B rolls on a hanger rail provided on the upper stile 1', and is mounted on the lower stile 3. The guide stopper 6 moves on the lower frame 1, and when the shoji B is opened and the shoji B starts to extend at an opening angle x as shown in FIG. It is designed to be locked into a locking hole on the lower frame 1 to lock the shoji B in that position. In the figure, 7 is a tightening handle.

However, when the opening angle x was small, the arm 2 crossed the opening lower frame 1 at an acute angle, making the shoji B unstable.

In buildings such as hotels and hospitals, it is often dangerous to have a large opening angle of a window, so the opening angle x is often restricted to a small value.

This project was proposed in view of these circumstances, and consists of an arm whose base end is rotatably pivoted to the opening frame, and whose tip is rotatably pivoted to the horizontal stile of the shoji. In the bay window, the base end of the auxiliary arm is rotatably pivoted to the arm, and the slide pin attached to the tip of the auxiliary arm is inserted into the slot provided in the longitudinal direction of the horizontal stile of the shoji. a pair of leg pieces are slidably fitted and arranged to sandwich the slot;
The present invention also relates to a sliding window characterized in that a U-shaped elastic member for engaging the slide pin with a widened free end is attached to the horizontal stile.

In this case, an auxiliary arm 8 is used, and the base end of the auxiliary arm 8 is rotatably pivoted to the arm 2, and the auxiliary arm 8 is attached to the lower frame 3 via a mounting screw 9 at the tip end. A slide pin 12 that slidably fits into a slot 11 extending in the longitudinal direction of the lower stile 3 provided on the slide base 10 is attached.

Reference numeral 13 denotes a U-shaped elastic member, the legs of which are placed between the slots 11, the free ends of which are widened, and the tips of which are inserted into the auxiliary arm slide base 10. The tightened leg pieces pass through the stepped portion 10a of the slide table 10, and the proximal end portion is formed into a curved portion 13a, and a positioning pin 14 installed on the auxiliary arm slide table 10 is locked in the same portion, The pin 14 prevents the elastic member 13 from swinging from side to side.

Further, at the base end of the auxiliary arm 8, there is a pin hole 8a into which a pin 15 mounted on the arm 2 is rotatably fitted, and a slot that communicates the pin hole 8a with the base end edge of the auxiliary arm 8. 8b, the diameter a' of the pin hole 8a is smaller than the diameter D of the head 15a of the pin 15, and slightly larger than the diameter a of the upper trunk 15b of the pin 15; The diameter c of 8b is smaller than the diameter a of the upper trunk 15b, and larger than the diameter b of the intermediate trunk 15c connected to the lower part of the upper trunk 15b. Also, the pin 15
is loosely inserted into the through hole of the arm 2 so as to be able to rise freely, and a biasing bullet 16 is interposed between the lower end collar piece 15d and the arm 2 to constantly press down the pin 15.

Therefore, by pushing up the pin 15 in the direction A in FIG. is adapted to be removed from arm 2.

In the figure, reference numeral 17 denotes a support metal fitting for the arm 2 that is fixed to the lower frame 1 via attachment screws 18, and 19 is a support metal fitting for the arm 2 that is fixed to the lower frame 3 via attachment screws 20.

Since the illustrated sliding window is constructed as described above, the shoji B can be moved from the closed state shown in FIG.
When opened as shown in the figure, the auxiliary arm 8 rotates around the pivot point to the arm 2, and the slide pin 12 is attached to the slot 11 of the auxiliary arm slide base 10 attached to the lower stile 3 of the shoji B. When the shoji B is opened to the opening angle x, the slide pin 12 is elastically engaged with the locking curved portion 13b of the elastic member 13, and the shoji B is at the opening position. be locked.

In this state, a triangular frame is formed by the lower stile 3, arm 2, and auxiliary arm 8 of the shoji B, and the shoji B is stably locked in its opening position even if the opening angle x is small. It is something that will be done.

Further, when closing the shoji B, the desired purpose is achieved by applying a force to the shoji B that is greater than the elastic clamping force exerted by the elastic member 13 on the slide pin 12.

Furthermore, when cleaning the outdoor glass surface of the shoji B, the base end of the auxiliary arm 8 is detached from the pin 15 of the arm 2, and the shoji B is rotated and reversed using only the arm 2. It is possible to achieve the intended purpose.

The base end of the auxiliary arm 8 may be detachably connected to the arm 2 by bolting, and the elastic member 13 may be constructed of a leaf spring or the like.

As described above, in the sliding window according to the present invention, the auxiliary arm is connected between the opening frame and the arm whose both ends are rotatably connected to the opening frame and the shoji horizontal stile, respectively. When the bay window is opened, a triangular frame is formed by the auxiliary arm, the shoji stile, and the arm, and the shoji can be stably locked in the open position even if the opening angle of the shoji is small. Also, by detaching the auxiliary arm from the arm, the shoji can be rotated by the arm alone, and the shoji can be rotated around the pivot point to the arm, thereby opening the outdoor glass surface. The indoor side can be cleaned more easily.
