Description

[Detailed Description of the Invention] The present invention relates to a tightening handle for a sliding soundproof sash used in buildings and the like.

Figures 1 and 2 are schematic diagrams showing ordinary sliding soundproof sashes, where 1, 2, 3.4 are window frames, A is an inner shoji screen,
The opening is the outer shoji, 5 is the upper stile of the inner shoji A, 6 is the upper stile of the outer shoji opening,
7 is the lower stile of the inner shoji A, 8 is the lower stile of the outer shoji entrance, 9 is the right vertical stile of the inner shoji A, 10 is the left vertical stile of the outer shoji entrance, 11 is the connecting stile of the inner shoji A, and 12 is the stile of the inner shoji A. Reference numeral 13 indicates the tightening handle of the outer shoji door opening stile.

This kind of tightening handle 13 is pivotally attached to the side of the connecting frame 12 of the outer shoji opening in order to prevent the intrusion of water, wind, sound, etc., and by operating this, the 15 inner and outer shoji openings are The left and right vertical frames 9 and 10 of the inner and outer shoji doors 49 and the window frames 2 and 4 are pulled together in the out-of-plane direction a and pressed in the in-plane direction, respectively.
This is to eliminate any gaps between the parts and to keep them airtight and watertight.

By the way, the conventional tightening handle 1 shown in FIG.
3 is an arm 15 attached to the same rotation axis when the handle 14 attached to the frame 12 of the outer shoji door is rotated 150 degrees.
is rotated by 90° via a differential mechanism.

At this time, the arm 15 has a roller 16 provided at its tip, and a catch 1 that is attached to the stile 11 of the internal shoji screen.
The roller 1 is hooked onto the protrusion 18 of the roller 1 to draw and tighten the inner shoji opening and the outer shoji opening toward each other in the out-of-plane direction a.
The spherical shaft head 16a of 6 is the inclined surface 1 of the catch seat 17.
7. Press and pull a to open the inner and outer shoji.

The mouth is configured to be pressed in the in-plane direction.

However, in the case of the conventional tightening handle having the above structure, when the window is closed, the shaft head 16a of the roller 16 is forcibly abutted against the inclined surface 17H, and each of the 49 openings of the inner and outer shojis is moved in the in-plane direction. If the handle 14 is pressed against the handle 14, sliding friction will occur at these joints, making it difficult to turn the handle 14.

Therefore, the present invention has been developed in view of the above-mentioned drawbacks of the conventional art, and the structure of the present invention will be described below with reference to the embodiments shown in the drawings.

In FIGS. 4 to 8, reference numeral 19 denotes a support stand fixed to the side surface of the stile 12 of the outer shoji opening, and this support stand 19
A handle 21 is attached to the convex portion 19a of the handle 21, which is pivotably held with the base of an arm 20 aligned with the same rotation axis.

Further, two rollers 22 and 23 are rotatably installed at the tip of the arm 20 in a cantilevered manner.The front roller 22 is for in-plane pressing, and the rear roller 23 is for out-of-plane pressing. A pulling roller is formed respectively.

24 is a catch fixed on the side of the stile 11 of the inner shoji,
Reference numeral 25 denotes a protrusion of a predetermined shape that protrudes along one side edge of the seat 24, and has an undercut angle α on its joint surface 25a.

Further, the catch surface 24a of the catch seat 24 forms an inclination angle having angles β and γ, where the angle β is formed along the horizontal direction of the catch seat 24, and the angle γ is formed along the horizontal direction of the catch seat 24. They are formed along the vertical direction.

The tightening handle according to the present invention has the protrusion 25 as described above.
The clearance angle α provided on the seat surface 24a and the angle β provided on the receiving surface 24a,
The reason for this is that γ is formed, and the effects of these will be explained below.

When the window is closed, the handle 21 attached to the side surface of the stile 12 of the outer shoji door is rotated 150° in the direction of the arrow, and the arm 20 attached to the same rotating shaft is rotated 90' via the differential mechanism.

Then, the rollers 22 and 23 provided at the tip of the arm 20 move along an arcuate trajectory as the rollers 22 and 23 rotate.

At this time, the outer peripheral surface of the roller 23 for pulling in the out-of-plane direction is
Due to the existence of the above-mentioned clearance angle α, the connecting frame 11 of the internal shoji i
comes into contact with the side edge of the protrusion 25 of the catch seat 24 fixed to the
A roller 22 for pressing in the in-plane direction in front of the roller 22 and a protrusion 25
without interfering with the joint surface 25a of the roller 23.
This makes it possible to hook it to the side edge of the protrusion 25.

Further, when the roller 22 for pressing in the in-plane direction is engaged with the roller 23 for pulling out of the plane, the roller 22 for pressing in the in-plane direction
4 A is brought into contact with a part of its upper surface and held in a cantilevered state.

This is due to the presence of the angle β formed on the seat surface 24a, and the roller 23 is hooked on the protrusion 25, causing the inner and outer shoji 1
When drawing the nine openings in the out-of-plane direction a, the in-plane direction pressing roller 22 rolls around the contact portion of the receiving surface 24a as a fulcrum.

Furthermore, as the roller 22 rolls, the inner and outer shoji 19
The mouth is gradually pressed in the in-plane direction.

This is due to the existence of the angle γ formed on the catch surface 24a of the catch seat 24, and this eliminates the sliding friction between the roller 22 and the catch surface 24a during the current fenestration pulling process. The handle 21 can be rotated by a rolling motion, which reduces pressure on the inner and outer shoji and the opening in the in-plane direction, and allows the handle 21 to rotate smoothly.

In addition, when pulling in the out-of-plane direction a, since the penetration angle α is formed on the joint surface 25a of the protrusion 25 of the catch seat 24, the roller 22 does not interfere with the joint surface 25a. The rotation operation of the handle 21 can be performed even more smoothly.

In summary, this invention has a roller for pulling in an out-of-plane direction and a roller for pushing in an in-plane direction, which can be rotated at the tip of the arm of a handle that is rotatably held on the side of the connecting frame of the outer shoji. At the same time, a catch having an integrally protruding protrusion having a clearance angle α is fixed on the side surface of the stile of the inner shoji, and the catch is fixed in the horizontal and vertical directions. Since the inclination angles β and γ are formed respectively, when the window is drawn to close, the front in-plane pressing roller does not interfere with the joint surface of the protrusion, and the rear out-of-plane pushing roller is used to press the inside and outside of the shoji. can be drawn to each other in an out-of-plane direction, and due to the inclination angles formed in the horizontal and vertical directions of the catch, the rollers for in-plane pressing roll and move the inner and outer shoji in-plane. Since the handle is pressed gradually in the direction, no sliding friction occurs during the pressing, and the handle can be rotated very lightly and smoothly.
