Description

[Detailed description of the invention] Industrial application field The present invention is a gremont method that fixes a shoji to a window frame in an out-of-plane direction by locking a locking member provided on the shoji side to a receiving member attached to the frame side. It concerns locks.

BACKGROUND ART As shown in FIG. 4, a receiving member 2 is attached to a vertical frame 1, a locking member 4 is provided on the vertical frame 3 so as to be movable in the vertical direction, and this locking member 4 can be rotated. The handle 6 is moved through the Gremont mechanism 5, which converts the movement into vertical movement.
A Gremont lock is known in which the locking member 4 is locked to the receiving member 2 by rotating the handle 6, thereby fixing the shoji to the window frame in an out-of-plane direction.

Problems to be solved by the invention The receiving member 2 is bent into a hook shape by the mounting piece 7 and the receiving piece 8, and the receiving piece 8 is linear in the in-plane direction, The locking member 4 has a shape in which a cylindrical locking piece 10 is provided on the main body 9, and the locking piece 10 is linear in the in-plane direction.
The locking piece 10 and the receiving piece 8 can be relatively displaced in the in-plane direction, and when a crowbar or the like is inserted into the gap t between the vertical frame 1 and the vertical stile 3 to pry it out, the gap widens. The locking piece 10 and the receiving piece 8 may come off, which is unfavorable from the viewpoint of crime prevention.

This is remarkable when the vertical frame 1 and the vertical frame 3 are made of synthetic resin.

Means and operation for solving the problem A substantially U-shaped receiving member is formed by a mounting piece, a protruding piece, and a receiving piece that are attached to the vertical frame, and a flange is provided on the main body that slides along the vertical frame. A locking piece is provided as a locking member, and the locking piece is brought into contact with the receiving piece, and the flange is positioned closer to the frame than the receiving piece, so that when the vertical frame and the stile are pried apart, the receiving piece and the flange are Interference prevents it from coming off in the in-plane direction.

Embodiment FIG. 1 is a cross-sectional view of the installed state, and shows the vertical frame 11.
is a hollow elongated member with a rectangular cross section, and a receiving member 13 is attached to one side wall 12, and this receiving member 13 has a mounting piece 14, a protruding piece 15 facing in-plane direction, and a receiving piece facing out-of-plane direction. 16 into a roughly U-shape,
The mounting piece 14 is fixed to one side wall 12 with screws 17.

The vertical stile 18 is a hollow long member with a rectangular cross section, and one side wall 19 thereof is formed with grooves 20 extending in the longitudinal direction, and the hollow part 21 is provided with a conventionally known structure for converting rotational motion into reciprocating motion. A Gremont mechanism 22 is installed inside the vehicle, and a handle 24 is connected to a rotating shaft 22a of the Gremont mechanism 22 from an indoor wall 23.

The locking member 25 includes a main body 26 that is movable along the groove 20 and a locking piece 27. The main body 26 has a plate shape and is connected to the reciprocating member of the Gremont mechanism 22, and the locking piece 27 has a cylindrical shape. It has a flange 28 at the tip and is connected to the main body 26.

Then, the outer peripheral surface 27a of the locking piece 27 is connected to the receiving piece 16.
The receiving piece 16 and the flange 28 overlap in the out-of-plane direction, and the flange 28 is located closer to the vertical frame 11 than the receiving piece 16 in the in-plane direction.

The end surface 16a of the receiving piece 16 has a lower linear surface 29, an inclined surface 30, and a higher linear surface 31 as shown in FIG.
Thus, the locking piece 27 rides on the high linear surface 31 from the low linear surface 29 along the inclined surface 30.

In addition, as shown in FIG. 3, the locking piece 27 may be a cylindrical roller, and the pin 32 provided with the collar 28 may be fixed to the main body 26 by passing through the roller.

Since it is like this, the receiving member 13 and the locking member 25
Because the receiving piece 16 and the flange 28 interfere with each other, they will not come off in the in-plane direction, and even if a crowbar or the like is inserted through the gap (t) between the vertical frame 11 and the vertical stile 18 to pry the receiving piece 16 together. Since it does not interfere with the flange 28 and come off, it is preferable for crime prevention.

Effect of the invention When the locking piece 27 of the locking member 25 is brought into contact with the receiving piece 16 of the receiving member 13 and the shoji is fixed to the window frame in an out-of-plane direction, the collar 28 of the locking member 25 is brought into contact with the receiving piece 16 of the receiving member 13. The mounting piece 14 is closer to the mounting piece 14 than the piece 16, and when a crowbar or the like is inserted through the crack between the vertical frame 11 and the vertical stile 18, the collar 28 of the locking member 25 and the receiving piece 16 of the receiving member 13 will interfere. It does not come off in the in-plane direction, which is preferable for crime prevention.

Claims (1)

[Claims for Utility Model Registration] Receiving member 1 attached to vertical frame 11 constituting a window frame
In the Gremont lock, which fixes the shoji to the window frame in an out-of-plane direction using a locking member 25 provided on the vertical stile 18 constituting the shoji, the receiving member 13 is attached to the mounting piece 14 attached to the vertical frame 11. A protruding piece 15 protruding in the in-plane direction from the mounting piece 14 and a receiving piece 16 extending out of the plane from this protruding piece 15 form a substantially U-shape, and the locking member 25 is attached to the vertical frame 18. It consists of a main body 26 that is slidably provided along the main body 26, a locking piece 27 that is attached to the main body 26 so as to protrude in the in-plane direction, and a collar 28 that is attached to the tip of the locking piece 27. When the piece 27 comes into contact with the receiving piece 16, the tsuba 2
