Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a thrust bearing connected to at least one locking rod and one of the actuating members of the main body mechanism, and also fixed to the case of the main body. This invention relates to a Clemon bolt or Clemon bolt lock equipped with a safety device for preventing home invasion that abuts in an effective position.

[Prior art and problems]

As already disclosed in patent application specification no. It is publicly known.

This blocking device is located between one of the actuating members of the mechanism and a slider forming the pivot of the locking rod of the Clemon bolt lock.

The blocking device has a lever connected at a fulcrum to the sliding portion of the locking rod. One end of this lever meshes with the actuating member of the mechanism, and the other end of the lever rests in the active position on a thrust bearing fixed to the Clement bolt lock or to the case of the Clement bolt.

Further, the other operating member of the mechanism is engaged with the final tightening bolt.

The role of the above-mentioned safety device of a Clemmons bolt or Clemmons bolt lock is to prevent any intrusion attempt that would actuate the locking rod and/or the locking member and push them into the unlocked position.

In the device disclosed in the above-mentioned FR-A-2,490,268, a lever connected to a rod is directly engaged with the actuating member of the mechanism. That is, in the case of a home invasion, the lever connected to the locking rod reacts to each moment applied to the locking rod and/or to the locking element integral with this locking rod.

The invention therefore aims to render the safety device insensible to uncontrollable vibrations that may be exerted by the actuation imposed on the locking rod and/or the locking member integral with this locking rod. do.

Means for Solving Problem C] The above object is to provide a thrust bearing in an effective position that is connected to at least one locking rod and one of the actuating members of the main body mechanism and is also fixed to the case of the main body. In a Clemont bolt or Clemont bolt lock with an abutting safety device for preventing home invasion, at least one of the connecting members connecting said safety device to the locking rod and one of the actuating members of the main mechanism is connected to the locking position and to the actuating rod. The connecting member is provided between the safety device and the actuating member and has a cylindrical projection integral with the actuating member. the protrusion is part of the actuating member and is engaged in a slot formed in the safety device, the central axis of which is aligned with the outer periphery of the actuating member of the body mechanism. Provided is the Cremon bolt or Clemon bolt lock as described above, which is tangential to a curve drawn by the center of the projection when it moves concentrically, and the longitudinal wall surface of the slot is in contact with a curve that limits the range of movement of the projection. This is achieved by

Applying these features, any attempt to bring the safety device into the unlocking (neutral) position by applying sudden or repeated movements to the locking member integral with the locking spout, C and/or this locking rod will be futile. become.

The invention is characterized in that the connecting member that connects the safety device to the actuating member has an idle stroke. In short, the connection member is provided with an idle stroke, and the t! ! By providing the slot member with a protrusion that engages the slot, the actuating member can continue its rotation slightly after the safety device has abutted against the thrust bearing, so that the central axis of the slot is aligned with the actuating member of the mechanism. It is tangent to the curve drawn by the center of the protrusion that is integrated with.

〔effect〕

According to the above characteristics, certain tolerances are allowed during the manufacture of the mechanism, in particular because the exact position of the rotor of the safety block, relative to which the key can be inserted and/or removed, is dependent on the mechanism. It is possible that the actuating member does not correspond to the exact position in which the safety device is brought into abutment against a thrust bearing integral with the case.

The fact that the actuating member can continue its rotation slightly allows the key to take up the correct position within the safety block for raising it.

The features described above also allow the protrusion to be cylindrical and to form a pivotal part of the mechanism actuating member.

By providing a dead stroke in the connecting member connecting the safety device to the actuating member, the present invention eliminates the dead lock by an additional rotational movement of the key when the Clement bolt lock is moved in its open position for 14 hours. It has the advantage of acting as a completely separate lock with a removable angle. In short, the idle stroke provided in the present invention allows the removable angle to be actuated without actuating the locking rod. Therefore, it is easy to eliminate empty locks through the removable angle for both locks and Clemon bolt locks.

Moreover, in order to preserve the advantages such as, on the one hand, the scales which give the mechanism a certain tolerance during manufacture, and, on the other hand, the key being able to take the correct position in the safety block for its lifting, the present invention is necessary. At least one idle stroke is provided between the tightening bolt and another actuating member of the mechanism, which is equal to the idle stroke of the connecting member connecting the safety device to the locking rod and the corresponding actuating member.

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Clemon Bolt or Clemon Bolt Lock 1 is Case 2
The front wall 3 of this case is covered with a side plate 4. This side plate 4 has two slots 5.6 through which the latch 7 and the final tightening bolt 8 pass. At least one locking rod with a slider slides behind the side plate 4 (the locking rod and the slider are not shown). The locking rod has a locking member for supplementing the latch 7 and the latch port 8.

Accordingly, the slider and the locking rod are actuated by a mechanism 9 which includes the locking rod, the latch 7 and the locking rod in a safety block 11 and/or an assembly of movable pieces transmitting the displacement of the locking member by the handle 10. It consists of a key that engages with a locking member such as a tightening bolt 8.

Via the handle 10, the keyhole 12 is rotated. This keyhole 12 has a first actuating pin 13 which cooperates with a return member 14 comprising an elastic member 15 which returns the handle 10 to a horizontal position upon release after actuation. This keyhole 12 also has a second actuating pin 16 which is connected to the latch 7.
It cooperates with the stopper 17 of the tail part 18 of. Said tail section 18
contacts the end 19 of the removable angle 20, which pivots about an axis 21 integral with the case 2. An elastic member 23 is inserted between the tail portion 18 and the rear wall 22 of the case 2.

When the handle 10 is operated downward (rotated clockwise), the keyhole 12
is rotated, and this keyhole acts through its first actuating pin 13 on the return member 14 and at the same time compresses the elastic member 15, and through its second actuating pin 16,
The latch 7 is retracted into the case 2 and the elastic member 23 is compressed, so that the latch 7 is guided by a thrust bearing 24 integral with the case 2.

When the handle 10 is released, the two elastic members 15
, 23 are extended, thereby forcing the latch 7 out and rotating the keyhole 12 in the opposite direction. However, in order to restrict the above-mentioned reverse rotation, a thrust bearing 2 integrated with the case 2 is required.
5 is provided.

The mechanism 9 has three actuating members 26 , 27 , 28 . The first actuating member 26 located close to the safety block 11 consists of a gear 29 actuated by a key and a pinion 30 that rotates integrally with this gear 29. This actuating member 26 rotates around a shaft 31 that is integral with the case 2. The pinion 30 is the gear 3 of the second actuating member 27.
It meshes with 2. The second operating member rotates around a shaft 33 fixed to the case 2, and has a pinion 34 that rotates integrally with the gear 32. The pinion 34 is engaged with a third actuating member 28 that rotates about a shaft 35 that is integral with the case 2 .

Case 2 is located between the third operating member 28 and the keyhole 12.
A thrust bearing 36 is inserted and installed.

The third operating member 28 operates the safety device 37. This safety device 37 is connected by a first connecting member 38 to the third actuating member 28 and by a second connecting member 39 to the locking rod. According to the invention, the coupling member 38 or 39 has a free travel 40 at least equal to the distance between the locking position and the end of the travel of the locking rod.

Preferably, the first connecting member 38 connecting the safety device 37 to the third actuating member 28 has the above-mentioned idle stroke 40.

The second connecting member 39 has a projection 41 that engages in a hole 42 which is integral with the locking rod and which hole 42 is formed in one end of the safety device 37. . In another embodiment, the protrusion 41 is integral with the safety device 37 and the hole 42 is drilled in the locking rod.

The first coupling member 38 also has a protrusion 44 which is engaged in a slot 45 allowing idle travel. According to the first embodiment, the protrusion 44 is integral with the other end of the safety device 37 and the slot 45 is provided at the third end of the mechanism 9.
It is formed on the actuation pin 47 of the actuation member 28. Also according to the second embodiment, the protrusion 44 is the third actuating member 2 of the mechanism 9.
8, and the slot 45 is drilled in the end 46 of the safety device 37. According to another embodiment, the projection 44 is a cylinder forming part of the third actuating member 28 of the mechanism 9.

Further, the center 48 of the projection 44, which is the center of the connecting member 39, draws a curve 49 concentric with the outer periphery of the third actuating member 28 of the mechanism 9. The central axis 50 of the slot 45 is in contact with the curve 49. Therefore, the longitudinal wall surface 51 of the slot 45
, 52 is a curve 53 that determines the movement range of the protrusion,
54.

The operation of the safety device 37 will be described below.

It is assumed that the Clement bolt lock 1 is first in the open position.

At this time, the protrusion 44 is connected to the terminal sinking 55 of the slot 45.
comes into contact with. One side of the plane connecting the center 48 of the connecting member 39 and the center of the connecting member 38 is inclined with respect to the linear path 57 of the projection 41, that is, with respect to the linear path of the locking rod. By actuating the key, the projection 44 is subjected to a free stroke via the actuating members 26, 27, 28 of the mechanism 9.

As the key continues to be turned, the protrusion 44 pushes against the safety 37 by contacting the other terminal sinking 58 of the slot 45, which in turn pushes the slider and locking rod assembly through the protrusion 41.

At the end of this stroke, the end 46 of the safety device 37 comes into contact with the thrust bearing 36. According to the slot 45, the protrusion 44
is moved further along the idle stroke 40, and the plane 56 is inclined on the other side of the straight path 57 of the protrusion 41.

The idle stroke 40 provides the mechanism 9 with its manufacturing tolerances and, on the other hand, rotates the third actuating member 28, i.e. continues to rotate the actuating member of the mechanism 9 to ensure that the key is safe during its retraction. It can be properly positioned within block 11.

In parallel, when the Clement bolt lock 1 is placed in its closed position by means of the key, the mechanism 9 also acts on the final tightening bolt 8. As a result, the final tightening bolt 8 is attached to the connecting member 5.
9 and an intermediate slider 60 to the second actuating member 27 of the mechanism 9.

The pinion 34 of this second actuating member is connected to a rack 61 formed in one of the sinkings 62 of the intermediate slider 60.
This slider is moved parallel to the slider of the locking lot. The intermediate slider 60 is provided at its upper end 63 with a projection 64 which presses against the tail 65 of the removable angle. Furthermore, the intermediate slider 60
has a slot 66 which cooperates with a projection 67 integral with the main tightening bolt 8, which projection 67 slides inside a straight slot 68 formed in the case 2.

The slot 66 has a ramp 69, each end 70, 71 of which communicates with a straight cylindrical end 72, 73 orthogonal to the straight slot 68 of the case 2. The central axis 74 of the cylindrical ends 72, 73,
75 are parallel to each other and parallel to the straight path 57 of the locking rod. The straight cylindrical ends 72, 73 are opposite in direction. Also, these cylindrical ends 72
, 73 are equal to the sum of the length 76, 77 is the thickness (diameter) 78 of the projection 67, and the idle strokes 79, 80. The idle strokes 79 and 80 are the same as the idle stroke 40.

When the Clemonport lock is closed with the key, the mechanism 9 that works together
The pinion 34 of the second actuating member 27 of the intermediate slider 6
Gives traction to 0. Under the action of the ramp 69 of the slot 66, the protrusion 67 is pushed into the linear slot 68 of the case 2 during the movement of the intermediate slider 60, and the final tightening bolt 8 emerges from that slot. Here, the idle stroke 79 not only provides the mechanism 9 with tolerances during its manufacture (but also allows the key to be returned to its proper position and withdrawn from the safety block 11).

When the Clemonport lock 1 is in the open position, the latch 7 can also be actuated by the key slightly in the opposite direction.

The second actuating member 27 of the mechanism 9 cooperates with the lever 61.
The pinion 34 provides a traction force to the intermediate slider 60. Here, due to the above-mentioned idle stroke 80, the straight cylindrical end 73 is moved along the projection 67 without acting on it, and also does not act on the main tightening bolt 8, so that The final tightening bolt maintains its retracted position. The protrusion 64 pushes against the tail 65 of the removable angle 20 and the angle rotates about the axis 21. The end 19 of said angle 20 presses against the tail 18 of the latch 7 and compresses the elastic member 23 but does not act on the keyhole 12. In parallel with this, the third actuating member 28 of the mechanism 9 rotates slightly and the protrusion 44 moves within the slot 45 but does not act on the safety device 37, the locking rod. The upward stroke of the intermediate slider 6° is regulated by a thrust bearing 81 fixed to the case 2.

When the key is released, the elastic member 23 extends and pushes back the end of the removable angle 20, whose tail 65 pushes back the intermediate slider 60 through the projection 64. This causes the mechanism 9 to rotate backwards, allowing the key to be pulled out. The protrusions 41 and 67 are the slots 4
5 and the straight cylindrical end 73 of the slot 66, so that neither the locking rod nor the final tightening bolt 8 acts.

Although the present invention has been described above with reference to specific embodiments, it should be understood that the present invention is not limited to these embodiments only, and that various modifications can be made without departing from the scope of the present invention. It can be implemented in various ways, materials, combinations of members, etc.
