Description

[Detailed Description of the Invention] The present invention relates to a device for adjusting the opening/closing degree of a window sash, and provides an apparatus that can extremely easily reverse the window sash.

. Embodiments of the present invention will be specifically described below.

The present device includes a mounting member 2 attached to a window frame 1, a swinging member 3 swingably connected to the mounting member, a support member 4 rotatably connected to the swinging member, and a support member 4 rotatably connected to the swinging member. An adjusting arm 5 slidably supported by a member, a connecting arm 6 rotatably connected to one end of the adjusting arm, a mounting member 8 fixed to a window sash 7, and the connecting arm attached to the mounting member. and restraining means for preventing relative sliding between the adjustment arm and the support member.

The mounting member 2 has a plate-shaped mounting pedestal 9 and a fork-shaped joint 10 that stands upright from the pedestal, and when the mounting pedestal 9 is fixed to the horizontal frame of the window frame with a fixing means such as a screw, , joint 10
is oriented horizontally.

The swinging member 3 has double plate-shaped pedestals 11 and 12, and a joint 13 stands up from the pedestal 11 at right angles, and the joint 13 is inserted between the joints 10 and 10 to connect it to the window frame 1. parallel pin 14
A cylindrical bearing 15 is connected to the joint 1 from the pedestal 12.
3 and stands in a direction perpendicular to the pin 14.

The support member 4 has a guide hole 16 with a rectangular cross section, which linearly guides the adjustment arm 5 inserted into the guide hole.

A shaft 8 having a threaded hole 17 in the center stands up from the support member 4 in a direction perpendicular to the guide hole 16 or the pin 14 and bears the bearing 1.
It is fitted into the bearing hole of No. 5 so as to be swingable or rotatable.

A washer 20 is present at the tip of the shaft 18, and the washer engages with a shoulder 21 in the bearing hole 19, and a screw 22 is screwed into the tapped hole 17 of the shaft from the washer side to secure the washer and the shaft. This connects the shaft to the bearing so that it can only rotate (Fig. 2).

The adjusting arm 5 has an H-shaped cross section, has a stopper 23 formed at one end thereof, and works together with a connecting arm 6 connected to the other end to open the guide hole 1.
I can't get past 6.

The connecting arm 6 has the shape of a plate-shaped body folded back into a U-shape, and the connecting arm 6 is pivotally connected to the adjusting arm 5 by a pin 24 at all ends thereof, and the pin 24 is oriented in a direction parallel to the axis 18.

The mounting member 8 includes a rectangular box-shaped main body 25 and a lid 26 that closes the opening surface of the main body, and is fixed so that the lid side is in contact with the window shoji 7.

As a means for connecting the connecting arm 6 and the mounting member 8, a connecting pin 28 having an annular groove 27 stands up at the tip of the connecting arm 6, and a connecting plate 30 having connecting holes 29' and 29'' that engages with the connecting pin 28 is provided as described above. It is incorporated into the main body 25 (FIG. 3).

A portion 31 of the connecting plate 30 extends from the hole in the main body 25 to the outside of the main body to form a push button, is guided by a guide surface 32 so as to be able to reciprocate on a straight line, and is always kept in the direction of the push button by a spring 33. is being attacked.

The connecting hole 29' is formed in a size that allows the connecting pin 28 to be inserted therein, and the connecting hole 29'' is formed in a size that communicates with the connecting hole 29' and allows the connecting pin to fit only into the annular groove 27 ( Figure 4).

When the connecting plate 30 is pushed in against the spring 33, the hole 29'
aligns with the hole 34 of the main body 25 and inserts the connecting pin 28 into the hole 29'.
can be inserted into the hole 29' or removed from the hole 29',
When the connecting plate is moved to its original position by the spring, the hole 29'' engages with the annular groove 27 of the pin 28, and the connecting plate 30 and the connecting pin 2
8 are connected.

A plate-shaped brake piece 35 is inserted into the gap between the guide hole 16 of the support member and the adjustment arm 5 as a restraint means for preventing relative movement between the adjustment arm 5 and the support member 4, and is inserted into the screw hole 36 of the support member. When the brake piece is pressed against the adjusting arm using the tightening screw 37, the adjusting arm is restrained, and when the push is released, the adjusting arm can move freely.

Further, when the steel ball 38 is inserted into the hole of the brake piece 35 and the steel ball is pressed against the adjustment arm with the tightening screw 37 via the spring 39,
Due to the magnitude of the tightening force, the steel ball cannot be removed from the recess 40 of the adjustment arm by wind force, but can be removed by human force. In this case, the window shoji can be automatically stopped at the desired recess position. It is convenient because it can be used (Figure 2).

A tightening lever 43 having a cam surface instead of the tightening screw 37
The brake piece 35 or the steel ball 38 may be pressed against the adjusting arm 5 by using the brake lever (FIG. 5).

If the brake piece 35 is made of a self-lubricating synthetic resin material, the adjustment arm can slide more quietly and smoothly than a metal one, and a large braking force can be obtained, making it easier to tighten. It is preferable to provide a steel plate 41 on the surface that is pressed by the lever or the tightening lever.

In FIG. 6, the window shoji 7 is a rotating window that rotates around a horizontal axis 42, and is in a closed state.

In this case, the connecting arm 6 of the adjusting arm 5 is located close to the supporting member 4 and parallel to the window shoji, and the supporting member 4 stands almost vertically, and the connecting arm 6 is perpendicular to the adjusting arm 5. ing.

From this state, when the window shoji 7 is pushed open in the direction of arrow A as shown in FIG.
At the same time, the support member 4 rotates in the direction of arrow C with respect to the bearing 15, and the bearing 15 rotates around the pin 14 in the direction of arrow B. Rotate in the direction.

When the push button 31 is pushed in, the connecting arm 6 is separated from the attachment member 8, and the support member 4 can be turned upside down while rotating around the pin 14 as shown by the chain line in FIG.

As a result, the shoji 7 can be reversed around the horizontal axis 42 in the direction of arrow F so that the outside faces the indoor side, and the outside shoji surface can be easily cleaned.

The window shoji 7 is used not only for horizontal axis rotation but also for vertical axis rotation. In this case, when the window shoji 7 rotates around the vertical axis 44 as shown in FIG. The support member 4 rotates only with respect to the swinging member 3 without rotating around it.

When reversing the window shoji, the connecting arm 6 is separated from the mounting member 8 in the same way as the horizontal axis, and the swinging member 3 is rotated in the direction of arrow E around the pin 14 of the mounting member 2 to stand it upside down. .
