Description

[Detailed Description of the Invention] This invention relates to a locking device in the open position of a shoji which is pivotally attached to a short frame of an opening of a swing shoji, a folding door, or the like.

Conventionally, as a locking device for the open position of a sliding shoji, etc., an arm pivoted to the lower stile of the shoji is slidably fitted into a guide tool rotatably fixed to the lower stile, and a screw provided on the guide tool is used. There are some types of shoji that have their arms tightened and fixed, allowing the shoji to be locked at any opening angle.

However, in this conventional example, the guide tool must be installed upright on a window sill or the like, and it becomes an obstacle for resting your elbow on the window.Also, since the guide tool is installed upright, it is easily damaged.

Furthermore, due to the structure, it is necessary to provide a pivot point for the arm on the shoji side on the side of the lower stile.

The object of this invention is to provide a device for fixing an opening shoji or the like at any position without having the above-mentioned drawbacks.

This idea features a guide strip on the opening side of the shoji that can lock a slide piece to the opening frame, one end of which is pivoted to the slide piece, the other end of which is engaged by a connecting rod pivoted to the shoji, and the slide The slide piece can be fixed at any position on the guide strip by a fastening device provided on the piece.

Embodiments of this invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment in a casement window.

A shoji 3 is pivotally attached to a short frame 2 of an opening frame 1 by hinges 10.

The arm stopper 4 of this invention is provided between the lower frame 5 and the lower stile 6 of the shoji 2.

2 and 3 are plan views of the arm stopper 4, and FIG. 4 is a developed view taken along the line A--A in FIG. 2.

FIG. 2 shows the shoji 3 in a fully open state, and FIG. 3 shows the shoji 3 in a closed state.

A wide T-shaped locking groove 7 is provided in the lower frame 5 on a vertical member that continues to the window sill.

A bracket 8 is fitted into the lower stile 6 and fixed with a small screw 9, and the other end of an arm 12, which is a continuous rod, is pivotally connected to the racket 8 with a pin 11.
It is pivoted by 4.

FIG. 5 is a sectional view taken along line BB in FIG. 2.

The slide piece 13 is in contact with the outer surface of the groove 7 and the fitted portion is fitted into the opening of the groove 7 with only sliding allowed, and the square shaft of the traction bolt 15 is slidably inserted into the square hole of the slide piece 13. One end of the traction bolt 15 has a male thread cut into it and a knob 16 is screwed into it, and the other end has rollers 18 rotatably fitted on both sides of a pin 17 press-fitted across parallel flats. There is.

At the position of the knob 16 in FIGS. 2, 4, and 5, the roller 18 and the slide piece 13 are tightened by the rotation of the knob 16, and are fixed mainly by the friction between the slide piece 13 and the lower frame 5. has been done.

When the knob 16 is tilted to the slack side between the screw of the traction bolt 15, the knobs 16 and 18 are moved away, and the slide piece 13 becomes movable along the groove 7.

During movement, since the rollers 18 rotate, the slide piece 13 moves without falling.

In FIG. 2, when the slide piece 13 is moved to the right, the pin 14
The arm 12 is pulled via the pin 11, and the arm 12 pulls the brackets 1 to 8 via the pin 11, so the shoji 3 rotates around the hinge 10 and moves inward.

When the knob 16 is raised at an arbitrary position, the slide piece 13 is fixed to the lower frame 5, and therefore the shoji 3 is also fixed.

When the knob 16 is pushed down and the shoji 3 is completely closed, the slide piece 13, knob 16, arm 12, bracket 8
The arms I and the brim 4 are stored below the lower stile 6 and are almost invisible from the open side of the shoji 3.

You can't see it at all from the closed side. That is, the arm stopper 4 is provided on a substantially horizontal plane and is provided in a narrow range in the vertical direction.

Figure 6 shows a shutter 3' on the outside of the shoji 3.
' is a double outward-opening sash that is pivotally attached to the short frame 2 so that both sashes open outward.

For such a sash, it is difficult to use conventional shoji locking devices such as the first one because they interfere with other objects on the shutter 3'.

The lower frame 5' faces outward from the window sill 19 and has a step 21 into which the shoji 3 enters. A step 22 into which the shutter 3' enters is provided, and grooves 7, 7' are provided in the vertical portion between each step, and brackets are provided on the lower stile 6 of the shoji 3 and the lower stile 6' of the shutter 3', respectively. l-
8 and 8' are fixed, and the groove 7, the lower stile 6, and the groove 7'
The arm stopper 4 described in the previous embodiment and the arm stopper 4' which is the same or almost the same as the arm stopper 4 and the lower stile 6' are mounted between the lower stile 6' and the arm stopper 4'.

It is better to have arms 1 to wings 4 and 4' with different lengths of arm 12 and different bending positions and angles to avoid interference with short frame 2, but (bracket) 8.8'
You can choose the location of and use the same one.

The shutter 3' is opened and closed by stacking the shoji 3 on the shutter 3' and connecting the shoji 3 and the shutter 3 with a fixture provided on the vertical frame.

To open, press the shoji 3 and the shutter 3' will open.

In the open position, the shoji 3 and shutters 3' are fixed.

In this embodiment, when the double shoji is opened in the same direction, the grooves 7, 7' are provided in the stepped portion of the lower frame 5', so there is no need to make the lower frame 5' particularly thick.

The arm stoppers 4 operate in different planes without interfering with each other, and when the shoji 3 and the shutters 3' are closed and stored, they are hardly visible from the outside and are not visible at all from the inside.

FIG. 7 shows the slide piece 13 engaged with the grooves 7 and 7' in each of the above embodiments and fixed movably.
In this embodiment, a locking protrusion 7'' having a T-shaped cross section is attached to the lower frame 5.
A slide piece 13' is provided, and one end of the arm 12 is pivotally connected to the slide piece 13'.

A male screw 24, which is fixed by a pin 23 driven into the knob 16', is screwed into the female screw cut into the slide piece 13'.

A T-slot provided on the slide piece 13' slides into the locking groove 7''.

When the knob 16' is turned down, the male screw 24 is unscrewed and the slide piece 13' becomes movable, and when the knob 16' is raised, the male screw 24 is screwed in and the slide piece 13' is attached to the protrusion 7''.
Fixed.

In this embodiment, the bracket 8 has the position of the pin 11 close to the lower stile 6, or the protrusion 7'', the bracket 8, and the arm 1.
The two ends are oriented differently in the horizontal direction.

As is clear from the above explanation, the slide piece may be guided by either a groove or a protrusion, as long as it is guided along the lower frame and has a shape that allows it to be fixed.

Further, the locking groove provided on the lower frame may be attached using a separate member.

The opening shoji arm stopper of this invention is not limited to the embodiments.

That is, in the case of the opening shoji shown in the embodiment, it may be provided between the first frame of the opening frame 1 and the upper stile of the shoji 3 and shutter 3'.

If the shoji is an opening shoji and is attached to the opening frame so as to be rotatable about a horizontal axis, it is installed between the short frame of the opening frame and the vertical stile.

In the case of a folding door, a similar arrangement can be made for the shoji on the side that is pivoted to the opening frame.

As described above, according to the arms 1 to flange of the outward opening window of this invention, the opening shoji can be fixed at any position, and the operation is simple and the installation is easy.

The manufacturing process is also simple because the guide strips can be extruded onto the opening frame.

It has a double-opening shoji and can be used for sash, other folding doors, and vertical casement windows that open and close on the same side, and can be stored in a convex I. The arm stopper is not visible from the outside and has a clean appearance.
