etc.) related to locks. The invention particularly relates to a barbed bolt pivoted to the case of the lock and operated by an operating member (which connects the bolt to the operating handle), and resilient means for biasing the bolt into the locking position. ,
a retaining means for retaining the bolt in the locked position; and a pusher for acting on the retaining means and urging the bolt to the locked position via the elastic means when the sliding wing is closed.
Relating to a type of lock equipped with.

[Prior art and problems]

A lock of this type is disclosed in French Patent Specification No. 794,886.

For security reasons, it is desirable to be able to lock the bolt in a locked position. That is, it would be advantageous to be able to negate an attempt to break into a home by inserting a razor or the like between a window (or door) and its frame to pry open a bolt.

The lock of French Patent Specification No. 794,886 is provided with a locking device for this purpose, but this locking device is adapted to be operated by a key.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sliding wing lock in which the bolt is locked automatically and without additional manipulation when the bolt is moved into the locking position.

[Means for solving problems]

Therefore, in the above-mentioned type of lock, the present invention provides that the operation member for operating the bolt is slidably housed in the case and is constituted by a holding means, and this holding means is connected to the other holding means connected to the bolt. The link between the operating member and the bolt is provided with an idle stroke such that the link between the operating member and the bolt is disengaged from the holding means of the operating member and the bolt at the unlocked position. It is characterized by

According to an arrangement of the invention, the bolt is automatically locked in the locking position. Also, when starting to operate the operating member, the lock is automatically released before the operating member brings the bolt to the unlocked position.

Further, according to the present invention, it is possible to interlock the bolt holding means with the operating member in the locked position.

In a preferred embodiment of the invention, the pusher acting on the holding means slides in the housing transversely to the operating member and cooperates with the abutment in each extreme position. The distance between the abutments is equal to the travel distance of the handle.

That is, according to this configuration, it is possible to realize an extremely small lock, and it is also possible to mount an exterior for the sliding wing of the sliding handle type.

If necessary, this sheath can be equipped with a security block that converts the entire lock into a lock for a sliding door, and the elastic member can be used to move the operating member from the neutral position to the unlocked or locked position. An over-center device can be used that biases the

According to the invention, deviations in the nominal extension of the pusher resulting from the precise positioning of the lock in the wing are easily compensated for by the adjustment means, and the case is moved into the wing by means of a screw and a counterscrew. Fixed.

If the lock has a certain length, it is advantageous to construct the adjusting means in such a way that the fixing means of the lock has a shaft at one end, which shaft allows for a slight rocking motion. This oscillation can be adjusted by means of a screw and a counterscrew at the other end.

[Embodiment] Referring to the drawings, a lock 4 is arranged between an outer wall 1 and an inner wall 2 of a sliding wing (shoji, window, or door) 3 of a window or door structure. When opening the sliding wing 3, the sliding wing 3 is moved in the direction of arrow A in FIG. 1, and when closing it, it is moved in the direction opposite to arrow A in FIG. The lock 4 has a case 5, which consists of two halves. Each half has a transverse wall 8, 9 and two walls 6, 7 parallel to the inner and outer walls 1, 2 of the sliding wing 3.

The case 5 has a hooked bolt 10, and the bolt 10 is rotatable about a shaft 11 attached to the case 5. For this purpose, windows 12 are provided in the walls 7 of the two halves of the case 5, which windows 12 are opposite to the windows 13 provided in the inner wall 2 of the sliding wing 3. These windows 12 and 13 allow the bolt 10 to be inserted, and the hook 14 of this bolt 10
protrudes from the outer surface 15 of the inner wall 2 of the wing 3 in the closed position of the lock 4. This hook 14 is connected to a catch 17 connected to a wing frame 18 of a window (or door) structure.
It works together with the counter hook 16. catch seat 17
is the inner member 19 in contact with the inner surface 20 of the frame 18
and an outer member 21 that abuts the outer surface 22 of the frame 18. Outer member 21 of inner member 19
The side surface 23 is provided with a boss 24 which traverses a window 25 in the wall 26 of the frame 18. These two members 19, 21 are joined by fixing members 27, 28 which cross the window 25. Since the boss 24 and the fixing members 27 and 28 cross the window 25, it is possible to position the seat 17 with respect to the window 25 depending on the position of the bolt 10.

The hooked bolt 10 is actuated by an operating member 29. According to the invention, this actuating member 29 slides inside the case 5 and is attached to the walls 1, 2 of the sliding wing 3.
move parallel to. The operating member 29 has an approximately U-shaped section in plan view, the opening of this U being located on the side of the inner wall 2 of the wing 3 . The inner surfaces 30, 31, 32, 33 of the walls 6, 7, 8, 9 of the case 5 serve as guides for the operating member 29. Operation member 29
The bolt 10 is operated by the handle 34 (in Fig. 1,
The link shaft 35 is shown). This link shaft 35 is connected to two of the operating members 29.
Windows 36, 3 provided in two parallel flanges 38, 39
7 and windows 40 and 4 provided on the side walls 8 and 9 of the case 5
It crosses 1. The long axes 42 of the windows 36 and 37 are perpendicular to the sliding direction of the operating member 29;
The long axes of 0,41 are parallel. The bolt 10 is connected to the operating member 2 by means of a link 43 having an idle stroke 44.
It is connected to 9. This link 43 has a horizontal axis 45
This transverse shaft 45 is connected to the bolt 10 and to the two windows 46, 47, which are also formed in the two parallel flanges 38, 39 of the actuating member 29. The bolt 10 is arranged between two parallel flanges 38 and 39.

The return of bolt 10 to the closed position shown in FIG. 1 is effected by resilient member 48. The elastic member 48 is connected to a stopper 49 connected to the case 5.
and a stopper 50 connected to the operating member 29. Each stopper 49, 50 has a guide 51, 52, and one end 5 of the elastic member 48.
3 and 54 are aligned with the guides 51 and 52.

Attempt to break into the home by moving the hooked bolt 10 to the locked position (this can be done, for example, by sliding a razor blade or the like between the wing 3 and the frame 18 and moving the bolt 10). Retaining means 55 are provided to lock the bolt 10 in the locked position. In a first embodiment of the invention, this retaining means 55 is a notch 5 formed in the bolt 10.
6 and a stopper 57 connected to the operating member 29. In the locking position, the working edge 58 of the notch 56 of the bolt 10 rests against the retaining edge 59 of the stop 57 of the actuating member 29. Therefore, wing 3
It is not possible to swing the bolt 10 in order to release it. Stopper 5 in notch 56
The engagement depth of 7 is slightly smaller than the free travel 44 of the link 43 between the bolt 10 and the operating member 29.

In the second embodiment, the holding means 55 is a stopper 57
It is constituted by a pin projecting from the inner surface of the bolt (which cooperates with a recess in the bolt 10).

Alternatively, the holding means 55 may be constituted by an operating finger provided on the upper part of the bolt 10 and a recess provided in the stopper 57.

This pin (or operating finger) is bolt 1
0 (or the stopper 57) into said recess is slightly smaller than the free travel 44 of the link 43 between the bolt 10 and the actuating member 29.

To unlock the bolt 10, the operating handle 34 is operated to begin sliding the operating member 29. With this start of sliding, the cooperative action between the notch 56 and the stopper 57 is released. At the start of said sliding, the link 43, in particular the shaft 45, closes the windows 46, 4.
7, the bolt 10 is not driven into the release position. To move to the release position, use windows 46 and 47.
This occurs only when the lower edges 60, 61 abut the shaft 45 and the bolt 10 is actuated by the operating member 29.

According to the invention, the lock 4 has a pusher 62. This pusher 62 passes through a window 63 provided in the wall 7 of the case 5, and also passes through a window 13 in the inner wall 2 of the wing 3. The pusher 62 slides laterally relative to the operating member 29. This pusher 62 is elastically biased toward the protruding position by an elastic member 64 interposed between the bottom 65 of the bore 66 in the rear surface 67 and the inner surface 30 of the wall 6 of the case 5.

A transverse slide 68 is provided on the rear face 67, the ends 69, 70 of which move within windows 71, 72 formed in the transverse walls 8, 9 of the case 5. The parallel flanges 38, 39 of the operating member 29 are provided with windows 73, 74. These windows 73,
74 is almost T-shaped, so there are two abutting parts 75,
76 is formed. Each abutting portion 75, 76 corresponds to an extreme position of the operating member 29, respectively. One abutment 75 is constituted by the upper edge of the vertical flanges of the T-shaped windows 73, 74, and the other 76 is constituted by the upper edge of the vertical flanges of the T-shaped windows 73, 74.
3.74 by the upper edge of the horizontal flange.

The distance 77 between the abutments 75 and 76 is equal to the travel of the operating handle 34 and therefore the operating member 29
is equal to the distance traveled.

The operation of this lock is as follows.

The operation handle 34 is operated to start sliding the operation member 29, and the engagement between the stopper 57 and the notch 56 is released. As the handle 34 is continued to be operated, the lower edges 60, 61 of the windows 46, 47 will move against the shaft 45.
As a result, the bolt 10 rotates about the shaft 11, and as a result, the lock 4 is unlocked.

At the same time, elastic member 48 is compressed. When the operating member 29 is displaced, the T-shaped windows 73, 74 slide along the slider 68 of the pusher 62, and the lower edges of the windows 73, 74 eventually abut the lower edges of the slider 68. When the sliding wing 3 is moved in the direction of arrow A in FIG. 1, the elastic member 64 expands while pushing the pusher 62 outward. Impact part 7
6 prevents the operating member 29 from returning due to the action of the elastic member 48.

When the wing 3 is closed, the catch seat 17 is moved by the elastic member 6
4, the pusher 62 is pushed back, so that the slider 68 comes within the vertical flanges of the T-shaped windows 73, 74 and releases the action of the elastic member 48. The elastic member 48 pushes back the operating member 29 while expanding, and the abutting portion 75 abuts against the upper edge of the slider 68. Since the windows 46 and 47 act on the shaft 45, the notch 56 engages the stopper 57 and the operating member 29
slides within the case 5 to return the operating handle 34.

By the way, this lock 4 can be equipped with an exterior for a sliding handle-type sliding fitting. If necessary, this exterior housing may be equipped with a security block that converts the lock into a lock for a sliding door. For this reason, an over-center device 78 is provided for biasing the operating member 29 from the neutral position to either the unlocked position or the locked position.

This over center device 78 has an elastic member 79
The elastic member 79 has two ends 80 and 81.
They are aligned with the swing axes 82 and 83 of the two swing members 84 and 85. The head 86 of the swinging member 85 is rotatable within a recess 87 formed in the side wall 88 of the operating member 29, and the head 89 of the swinging member 84 is rotatable within a recess 90 formed in the wall 7 of the case 5. It can be rotated. recess 9
0 is immovable, but the recess 87 is movable from a low position corresponding to the locked position of the lock 4 to a high position corresponding to the unlocked position. The distance between the low and high positions is equal to the travel of the operating handle 34. When the operating handle 34 is operated to operate the operating member 29, the elastic member 79 is compressed. Operation member 2
9 passes the neutral position, the elastic member 79 acts on the operating member 29 while expanding, and the operating member 29 is reliably brought to the unlocked or locked position.

However, for good operation of the lock 4, it is necessary that the nominal protrusion of the pusher 62 from the outer surface 15 be equal to the width of the abutment 76, allowing the bolt 10 to protrude. Since the lock 4 is placed in the wing 3 with considerable precision, this nominal protrusion tends to be insufficient and prevents the lock 4 from operating.
That is, if the travel distance of the pusher 62 does not match the nominal extension amount, the mechanism for closing the bolt 10 will deteriorate.

The invention therefore provides means for adjusting the position of the lock 4 with respect to the inner wall 2 of the wing 3.

In its first embodiment, this adjustment means consists of screws 91, 92 arranged at both ends 94, 95 of the case 5.
and a facing screw 93, and a lock 4 is attached to the wing 3.
to allow it to be fixed.

The second method is particularly advantageous when the length of the lock 4 is quite long.
In an embodiment, this adjustment means
It consists of a hub 96 fixed to the inner wall 2 of the housing with screws 91. This hub 96 is provided with a trunnion 97 which passes through bores 98, 99 formed in extensions 100, 101 of the upper ends of the side walls 8, 9 of the case 5. Therefore, the lock 4 can swing slightly about the trunnion 97 and its position can be adjusted by means of the screw 92 and the screw 93 acting on the lower end 95 of the lock 4. In this way, deviations in the nominal protrusion amount of the pusher 62 can be compensated for.
