Description

[Detailed description of the invention] This invention relates to a tightening handle device for sliding doors in which the inner and outer shoji are locked and simultaneously pushed in the closing direction by operating the handle.The purpose of this invention is to provide strong tightening with simple operation. The purpose is to improve the airtightness and soundproofing between the inner and outer shoji and the window frame (door frame).

The feature of this invention is that a tightening member that rotates in conjunction with the handle is fitted onto the shaft of a tightening handle that is rotatably provided on the sliding frame of one shoji. In a tightening handle device for a sliding door in which this tightening member is pressed against a member having a tapered surface provided on a matching stile of the other shoji to press both shojis in the closing direction, The tightening member is fitted so as to be movable in seven axial directions relative to the handle shaft, and an inclined guide groove is provided on the circumferential surface of the tightening member, and the guide groove includes:
A tightening handle device for a sliding door configured to engage a pin protruding from the handle shaft and move the tightening member toward the member by rotating the handle in the tightening direction. exists in

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

The present invention is applicable to all types of sliding doors, including sliding sash windows.

Referring to FIG. 1, 1 is a window frame, 2 is an inner shoji, and 3 is an outer shoji, and the tightening/handle device according to the present invention is attached to the vertical center of the connecting frame 2L31 of the inner and outer shoji 2 and 3. will be equipped.

4 is a tightening handle, 41 is a handle shaft, and the handle 4 is rotated by rotatably supporting the handle shaft 41 on a handle seat 5 fixed to the outer surface of the matching frame 31 of the outer shoji 3. Installed as possible.

Reference numeral 6 denotes a tightening member, and by loosely fitting its base end 61 onto the handle shaft 41 between the handle 4 and the handle seat 5, the tightening member 6 can be rotated in place of the handle shaft 41. It is installed on.

An engagement rod 62 is fixed to the tip of the tightening member 6, and the tip surface 62a of the rod 62 is formed into a spherical shape.

Reference numeral 63 indicates a collar that is loosely fitted onto the protrusion rod 62.

At the portions of the tightening handle 4, the handle seat 5, and the tightening member 6 that contact each other on the handle shaft 41, there are stoppers 4a projecting in the axial direction.

5a and 6a are provided, these stoppers 4at5
Due to the engagement of a and 6a, the handle 4 and the tightening member 6
The rotation angle is regulated to a constant value.

That is, the toilet 4 and the tightening member 6 are in a vertical position in the unlocked state, and the tightening member 6 is in a forward position 90 degrees when locked.
0 rotations...and the steering wheel 4 rotates at a larger angle than this (15
It is designed to be able to rotate (approximately 0°).

Further, as shown in FIG. 3, the tightening member 6 is fitted onto the handle shaft 41 in the vertical position so that a gap m is formed between the tightening member 6 and the handle seat 5. 6. It is constructed so that it can slide in the axial direction along the handle shaft 41 with a stroke of the above-mentioned gap m.

On the other hand, an inclined guide groove 7 is provided along the circumferential direction on the circumferential surface of the tightening member 6, and a pin 8 fixed to the handle shaft 41 is engaged with the guide groove 7.

The guide groove 7 is formed in an inclined shape in a direction that gradually approaches the direction of the tightening rotational force.

Therefore, when the nodule 4 is rotated in the tightening direction, the engagement between the pin 8 and the guide groove 7 causes the tightening member 6 to...
It will slide toward the steering wheel seat 5 side.

Reference numeral 9 denotes a member for the fastening member 6, which is fixed to the outer surface of the matching frame 21 of the inner shoji 2.

The member 9 has a tapered surface 91 on the upper part for guiding the engaging rod 62, and an engaging piece 92 on the edge of the outer shoji side of the central part for engaging the rod 62. ing.

Next, the effect will be explained.

When unlocking, both the tightening handle 4 and the tightening member 6 are in a vertical position as shown in FIGS. 1 to 3 and by the imaginary line in FIG. 5, and at this time the pin 8 is positioned at one end of the guide groove 7. are doing.

When the handle 4 is rotated as shown in Fig. 4.5 in order to lock the inner and outer shoji 2 and 3, the tightening member 6 rotates forward by 90 degrees in conjunction with this. Its engagement bar 6
The distal end surface 62a of 2 is guided by the tapered surface 91, and the receiver is brought into pressure contact with the member 9 and engaged with the engagement piece 92 of the member 1.

As a result, the inner and outer periphery shoji 2.3 are locked, and at the same time they are moved in the closing direction, that is, both the left and right vertical frames 11, 1 of the window frame 1.
Pressed to the 2nd side.

In this case, the tightening member 6 is rotated simultaneously with the start of rotation of the handle 4 due to the contact resistance between the pin 8 and the guide groove 7, the frictional resistance between the base end 61 of the member and the handle shaft 41, etc. It begins to move.

When the distal end surface 62a of the engagement rod 62 comes into contact with the tapered surface 91 and rotational resistance is applied, the tightening member 6 stops and the pin 8 moves within the guide groove 7, thereby causing the tightening member The 6-piece receiver slides toward the member 9 side.

When the handle 4 rotates at a certain angle in this way, the collar 4a of the handle 4 hits the stopper 6a of the tightening member 6, and the tightening member 6 is then in the locked position.・Rotates together with the handle 4.

Concerning the operation of the fastening member 6, such as a button or °) There may be cases where the tightening member 6 begins to rotate due to the action of the stopper from the moment it rotates, but in either case... the tightening member 6 changes from the unlocked position to the locked position by the handle operation. There is no change in the effect that the receiver slides toward the member 9 during the cutting.

In this way, due to the handle operation, the clamping member 6 and the receiver slide from their original pressure contact position against the member 9 toward the member, so that the clamping member 6 and the receiver are affected by the pressure contact force with the member 9. becomes extremely large.

Therefore, since the inner and outer peripheral shoji 2 and 3 are pressed in the closing direction with great force, the airtightness, watertightness and soundproofing between the shoji 2 and 3 and the window frame vertical frame 1L12 are significantly improved. .

In the above embodiment, the clamping member 6 is forcibly rotated within a certain range of angles using the stoppers 4a and 5a. It is also possible to slide in the axial direction while being rotated even after the rotation resistance is applied.

Further, the rotation angle of the tightening member 6 may be regulated by having the receiver on the member 9 side.

As shown in the upper part 1, according to the present invention, not only can the tightening member be rotated by a simple handle operation, but also the receiver can be slid toward the member, so that the tightening member and the receiver can be moved easily. By pressing the members together with an extremely strong force, the inner and outer shoji can be strongly pressed in the closing direction, thereby improving airtightness, watertightness, and soundproofing between both shojis and the vertical frames on both sides of the window frame (door frame). It is something that can significantly improve
