Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a stop device that limits the opening degree of a shoji screen in a sliding window.

Prior art In order to limit the opening degree of the shoji in a sliding window, a configuration is generally adopted in which stoppers are provided protruding from opposite sides of the vertical frame of the window frame, and sliders protruding from the left and right sides of the upper end of the shoji come into contact. has been done.

However, when the weight of the shoji increased, a large impact was generated when the slider came into contact with the stopper, which could damage the stile or glass plate.

In order to solve such problems,
In the invention described in Japanese Patent No. 54439, a compression spring is made to protrude above the stopper so that the slider of the shoji comes into contact with the compression spring to soften the impact.

Problems to be solved by this invention However, the problem with this invention is that the compression spring is simply housed in a cylindrical case installed in the vertical frame, and as the shoji opens and closes, the stopper also compresses. The spring may fall off.

Composition of the invention The shoji stop device for a sliding window according to this invention includes a case in which a stopper is fixed to a vertical frame, a stop pin slidably disposed within the case,
Composed of a compression spring, the stop pin has an upper end protruding above the case, and a locking part formed at the bottom to lock in the case and prevent it from coming out, and is further urged upward by the compression spring. This solves the above problems.

Embodiment This invention will be described in detail below based on an embodiment shown in the drawings.

The slide-out window shown in FIG. 3,

Shoji B has sliders 6 protruding from the left and right sides of the upper end.
6, the sliders 6, 6 can abut on stoppers 7, 7 attached to the opposing surfaces 2a, 2a of the vertical frames 2, 2, and the opening degree of the shoji B can be adjusted. is restricted. On the left and right sides of the shoji B, one end of the arms 8, 8 is pivoted to the vertical frames 2, 2, and the other ends of the arms 8, 8 are pivoted, and the arms 8, 8 support the shoji B.
Guidance on opening and closing.

The sliders 6, 6 are fixed to the ends of round bar-shaped pins 6c, 6c, respectively. It is slidably and rotatably housed inside. A pin insertion hole 10 parallel to the longitudinal direction of the upper stile 3 is horizontally penetrated through the case 9, and a female screw 11 is screwed into the inner peripheral surface of the end of the pin insertion hole 10 on the other side of the case 9. There is. An adjustment screw 12 is screwed into the pin insertion hole 10. A compression spring 13 and a pin 6c are sequentially inserted into the pin insertion hole 10 from the end side of the upper stile 3, and the slider 6 is biased toward the vertical frame 2. In order to adjust the biasing force in the direction of the vertical frame 2, the screwing length of the adjustment screw 12 may be adjusted. The indoor and outdoor surfaces 6a, 6a of the sliders 6, 6 are formed into mutually parallel planes, and the side surface of the lower vertical stile 4 has a tapered surface 6b that gradually separates from the vertical stile 4 as it goes downward.
is formed.

The vertical frame 2 of the window frame A has a substantially U-shaped cross section and is formed with a groove 14 that opens on the opposite vertical frame 2 side, and the indoor side surfaces 6a, 6a of the slider 6 are connected to the vertical frame 2.
It is able to slide up and down within the groove 14 in sliding contact with the indoor and outdoor walls.

The stopper 7 is composed of a case 15 fixed to the vertical frame 2, a stop pin 16 slidably disposed within the case 15, and a compression spring 17.

The case 15 is fixed to the facing surface 2a of the vertical frame 2 by a plurality of screws 18 which are vertically spaced apart and penetrated horizontally. The screw 18 passes through the facing surface 2a of the vertical frame 2 and is screwed into a nut 20 welded to a back plate 19 that is in contact with the outer surface of the vertical frame 2. The nut 20 is hidden by a box-shaped cover 21 fixed to the back plate 19.

In the case 15, a stop pin housing hole 22 and a compression spring housing hole 23 each having a circular cross section are vertically continuously formed. The upper end of the stop pin housing hole 22 is opened on the upper surface of the case 15, and the diameter of the compression spring housing hole 23 is formed to be slightly larger than the stop pin housing hole 22.

The upper portion of the stop pin 16 has approximately the same diameter as the stop pin housing hole 22, and a locking portion 24 having approximately the same diameter as the compression spring housing hole 23 is formed at the lower end. . The upper part of the stop pin 16 is housed in the stop pin housing hole 22, the locking part 24 is housed in the compression spring housing hole 23, and the stop pin 16 is vertically slidable and housed in the compression spring housing hole 23. The case 15 is compressed by the compressed spring 17.
is biased to protrude upward from the top surface of the
Further, the locking portion 24 of the stop pin 16 is locked to the upper end of the compression spring storage hole 23, so that the stop pin 16 can be locked.
is prevented from escaping.

An engaging portion 25 that projects upward is formed at the end of the upper surface of the case 15 on the shoji B side. A surface 25a of the engaging portion 25 on the vertical frame 2 side is formed in a tapered shape so as to be gradually separated from the facing surface 2a of the vertical frame 2 that faces each other as it goes upward.

Further below the stopper 7, left and right secondary stoppers 26 are provided to protrude from the facing surface 2a of the vertical frame 2. A screw 27 is passed through the secondary stopper 26 horizontally, and the screw 27 is inserted into the opposing surface 2a of the vertical frame 2.
It is also passed through and screwed into a back plate 28 which is in contact with the outer surface of the vertical frame 2. On the upper surface of the secondary stopper 26, an engaging portion 29 is protruded from the end on the shoji B side, and the surface 30 of the engaging portion 29 on the vertical frame 2 side gradually engages the vertical frame 2 as it goes downward. It is formed in a tapered shape so as to be close to the facing surface 2a. The reason why the engaging portion 29 is provided protrudingly provided on the lower surface of the secondary stopper 26 is that the secondary stopper 26 can be used in left and right directions.

Hereinafter, the operation of opening and closing the sliding window having the above-described configuration will be explained.

When opening the shoji B, since the sliders 6, 6 are brought into contact with the opposing surfaces 2a of the vertical frames 2, 2 by the compression springs 13, 13, the friction between the sliders 6, 6 causes the shoji B to open. It is possible to open smoothly without opening abruptly.

When the shoji B is further opened, the sliders 6, 6 move further downward, but since the stop pins 16, 16 protrude upward from the upper surface of the stoppers 7, 7, they first come into contact with the stop pins 16, 16, and the compression spring 17 , 17, the impact is alleviated. Therefore, even if the weight of the shoji B is large or the sliders 6 descend due to acceleration, the stopper 7, the slider 6, the stile 3, the glass plate 5, etc. will not be damaged due to the cushioning.

When the shoji B is further opened, the sliders 6, 6 further descend and push down the stop pins 16, 16, so that the tapered surfaces 6b of the sliders 6, 6 move toward the cases 15, 1.
Each of the engaging portions 25 of No. 5 slides into vertical frame side surface 25a, and blurring due to left and right inclination of the shoji B is corrected.

When cleaning the glass plate 5 of the shoji B, the screws 18 of the stoppers 7, 7 are removed, the stoppers 7, 7 are removed, and the shoji B is further opened. When the shoji B is opened, the sliders 6, 6 further descend and come into contact with the secondary stoppers 26, 26 in a substantially horizontal state. In this state, it is sufficient to extend an arm from between the upper stile 3 of the shoji B and the upper frame 1 of the window frame A and sweep the outdoor side surface of the glass plate 5.

Effects of the invention This invention consists of the above-mentioned structure, and this stopping device absorbs the impact when the shoji is opened by using a stop pin that is biased by a compression spring that is biased upward, and a tapered surface provided on the slider. It can be softened by sliding it along the surface formed on the engaging part of the stopper.
It is possible to prevent the shoji from popping up, which occurs when only the biased stop pins are used, and to prevent damage to the functions attached to the shoji and breakage of the shoji, and to stop the slider at an appropriate position of the stopper. I can do it.
