Description

LOCK CYLINDER WITH NOTCH TECHNICAL FIELD The present invention relates generally to a door lock and, more particularly, to a notched lock cylinder for use with the notched lock.

PREVIOUS TECHNIQUE A notch lock mechanism typically includes a box provided with an opening for the lock cylinder, adjacent to a lock. A lock cylinder assembly of similar cross section is disposed in the opening for said cylinder. The lock cylinder assembly has a device for actuating a bolt through such a lock cylinder. The actuator engages with the latch of the notched lock mechanism to operate the bolt. In a configuration commonly referred to as "lock with cylinder" profiled, the same actuators of the lock are located on the opposite sides of the door, one of such actuating mechanisms of the lock (eg, external) is a keyed mechanism.

It has been difficult to try to adapt a notched lock fitted with a single-cylinder euro profile, to applications in which the axial space is limited, such as a thin door application or when it is desired that the entire projection of the cylinder from the face of the door be as low as possible. Previous attempts to solve the problem require more space in the cylinder in longitudinal direction, since the tip of the key is used to rotate an internal clutch. When doing so, a significant portion of the axial space of the cylinder must be free of any obstruction, which may become impractical if the projection of the cylinder becomes too long.

BRIEF DESCRIPTION OF THE INVENTION In one form, the present invention relates to a notch lock cylinder, which includes a rotating part assembly carrying a rotating part and a first clutch. The rotating part is in drive coupling with the first clutch, which has a neutral position. A cylinder assembly with a key is configured to be operated by a key. The key cylinder assembly includes a second clutch and a cylinder body having a keyhole. The lock body is in drive coupling with the second clutch. A cover is configured with a longitudinal cavity. The cover has a first end spaced from a second end. The longitudinal cavity extends along a longitudinal axis between the first end and the second end. A first portion of the rotating part assembly is received at the first end and a second portion of the key cylinder assembly is received at the second end. The cover has a central portion with a cam groove formed in the cover extending perpendicularly towards the longitudinal extension of the longitudinal cavity as well. A cam is disposed in the cam groove and is mounted to rotate about the longitudinal axis. The notched lock cylinder is configured so that the cam is always engaged in a driving manner with the first clutch and is configured so that the second clutch is engaged in a driving manner with the cam through the first clutch, when it is inserted into the first clutch. the key in the cylinder set provided with a key.

In another form, the present invention relates to a notch lock cylinder, which includes a rotating part assembly that includes the latter and a first clutch. The rotating part is in drive coupling with the first clutch. This first clutch has a neutral position spaced longitudinally from a non-neutral position.

The longitudinal cavity extends along a longitudinal axis between the first end and the second end. A first portion of the rotating part assembly is received at the first end and a second portion of the key cylinder assembly is received at the second end. The cover has a central portion with a cam groove formed in the cover, which extends perpendicularly to the longitudinal extension of the longitudinal cavity. There is a cam arranged in the cam groove. The notched lock cylinder is configured so that the first clutch is rotatably fixed with the cam and configured so that the second clutch engages the first clutch in a driving manner when the key is inserted into the keyhole of the lock body , so that the cam is operable by means of said key.

In another form, the present invention relates to a method for operating a notched lock cylinder. The method includes: providing a rotating part assembly that includes the latter and a first clutch; said rotating part is in drive coupling with the first clutch; providing a key cylinder assembly configured to be operated by a key and which includes a second clutch and a lock body having a keyhole; the lock body is in drive coupling with the second clutch; providing a cover for receiving a first portion of the rotating part assembly and receiving a second portion of the key cylinder assembly; the cover has a central portion with a cam groove; providing a cam in the groove and mounted on both the first portion of the rotating part assembly and the second portion of the key cylinder assembly; fit in shape driving and permanent to the cam with the first clutch, so that said cam is always in rotating condition by means of the rotating part; and coupling the second clutch with the cam in a driving manner through the first clutch when it is inserted into the key in the cylinder assembly with a key.

As such, the present invention provides a design solution for a notched lock with Euro profile of a single cylinder, in a thin door application where the axial space is limited or when the projection of the entire cylinder from the face of the cylinder is desired. door as low as possible.

DETAILED DESCRIPTION OF THE INVENTION Referring now to Figure 1, a lock is illustrated 10 with notch of the type well known in the art. The notched lock 10 includes a cover 12 having an opening 14. Said cover 12 carries a lock pin 16 and contains an internal lock mechanism (not shown) provided with a spring latch, for example the latch 18. The opening 14 is configured with a size and shape suitable for receiving a profiled lock cylinder, such as a lock cylinder 20 with notch configured in accordance with a form of the present invention. The notched lock cylinder 20, when installed in the opening 14, is coupled in a drive with the internal lock mechanism and in turn with the latch 18.

Referring now to Figures 2-5, cylinder 20 with notch lock is illustrated in detail. This cylinder 20 includes a cover 22, a cam (for example, a cam assembly) 24, a rotating part assembly 26 and a key cylinder assembly 28. The cam 24 is engaged to rotate with the rotating part assembly 26 and can be selectively engaged to rotate with the key cylinder assembly 28. Thus, a cam 24 is configured to operate the latch 18 by actuating either the rotating part assembly 26 or the key cylinder assembly 28.

Referring now to Figure 5, the notch lock cylinder cover 22 has a first end 30 spaced from the second end 32 along a longitudinal axis 34. A longitudinal recess 36 extends along the longitudinal axis 34 between the first end 30 and the second end 32, each of which is configured to receive a respective portion of the rotatable part assembly 26 and the key cylinder assembly 28. The longitudinal axis 34 defines a co-axis of rotation for the rotating part assembly 26 and the key cylinder assembly 28 and thus, for clarity and convenience, the longitudinal axis 34 can sometimes be referred to as the co-axis of rotation 34. Located in a central portion 38 of the cover 22 of the notched lock cylinder is a cam groove 40 which extends radially perpendicular to the longitudinal extent of the co-axis of rotation 34 and the longitudinal cavity 36. The groove 40 cam is configured to receive cam 24.

Referring also to Figures 6A and 6B, the rotating part assembly 26 includes a rotating part 42, a cover 44 for the retainer, a rod 46, a set screw 48, a retaining ball 50, a stop spring 52, a compression spring 54, a first clutch 56 and a pin 58.

The stem 46 includes a proximal end 60 and a distal end 62. A guard portion 64 extends a certain distance from the proximal end 60 and a cylindrical portion 66 extends proximally from the distal end 62. An annular shoulder 68 is located at the point of attachment of the guard portion 64 and the cylindrical portion 66. A guard portion 64 is configured to be received in a corresponding opening located in the rotating part 42 with similar shape and dimension in the cross section. A characteristic annular element 69 is located at the distal end 62 of the shank 46.

The cylindrical portion 66 is configured to be received in the longitudinal cavity 36 in the first end 30 of the notch lock cylinder cover 22. The cover 44 of the retainer is configured to be positioned over the guard portion 64 and in longitudinal contact with the annular shoulder 69 to retain the cylindrical portion 66 in the longitudinal cavity 36 of the notch lock cylinder cover 22 and restrict the movement of the rotating part assembly 26 along the longitudinal axis 34. The cover 44 of the retainer is fixed to the cover 22 of the notched lock cylinder by conventional coupling techniques such as, for example, friction coupling, staking, welding , etc. The rotating part 42 is fixed longitudinally to the guard portion 64 by the fixing screw 48.

As used here, the term "fixed" or its variations I I means a coupling of the components that prevents a movement relative among them. In the same way, the term "fixed" can be used to describe a conditional fixation and / or a temporary fixation, as will be understood in the context in which the term is used. By example, one component can be set to another component in terms of í rotating motion, or rotationally fixed, and yet such components may be able to move with respect to each other longitudinally to a certain limited extent, that is, the components do not They are fixed longitudinally within the limited scale of longitudinal movement.

The cylindrical portion 66 has a hollow interior 70 that extends proximally from a distal end 62 and ends to form a I internal terminal wall 72. Cylindrical portion 66 includes a pair of slots 74 diametrically opposed at the distal end 62. The portion ji cylindrical 66 has a through hole 76 extending diametrically and the which intersects the hollow interior 70 between the distal end 62 and the wall internal terminal 72.

Referring now to Figures 7-14, the first clutch 56 includes a portion 78 of cylindrical shank configured to be received slidably in the hollow interior 70 of the cylindrical portion 66 of the stem 46 along the longitudinal axis 34. As better illustrated in Figure 6A, the first clutch 56 has a first end 80, a first portion terminal 82, a second end 84 and a second terminal portion 86.

The first end portion 82 includes a groove 88 diametrically extended and displaced axially along the longitudinal axis 34 from the first end 80. The second end portion 86 includes a pair of diametrically opposite tongues 90. The second terminal portion 86 further includes a characteristic slot member 92 in the form of a pair of diametrically opposed slots 92. In the present form, the diametrically opposed grooves 92 are displaced rotationally, for example by 90 degrees, from the diametrically opposite tongues 90 in the second end portion 86 of the first clutch 56. The latter has a hollow interior 94 extending proximally from the second terminal portion 86 and ends to form an internal terminal wall 96.

It is assembled to the rotating part assembly 26 in the following manner. The compression spring 54 is inserted into the hollow interior 70 of the cylindrical portion 66 of the shank 46. It is then inserted to the portion 78 of the cylindrical stem of the first clutch 56 in the hollow interior 70 of the cylindrical portion 66 of the shank 46, with the compression spring 54 interposed between the inner end wall 72 of the cylindrical portion 66 of the stem and the first end 80 of the first clutch 56. Thus, the first clutch 56 is urged by the action of the spring in a direction 95 towards the assembly 28. cylinder with key by means of compression spring 54.

As best illustrated in Figures 3, 6B and 7, with the compression spring 54 somewhat compressed and with the tongues 90 diametrically opposite of the first clutch 56 temporarily received in sliding manner by the diametrically opposed grooves 74 of the rod 46 to accommodate the assembly, is aligned diametrically to the through slot 88 of the first clutch 56 with the through hole 76 of the rod 46 and is inserted into the pin 58 through the through hole 76 and the through slot 88, so that the pin 58 forms a frictional fit with the opposite ends of the through hole 76 of the shank 46. Therefore, the first clutch 56 is rotatably fixed with respect to the stem 46 of the rotating part assembly 26 relative to the longitudinal axis 34, but the first clutch 56 can slide in the longitudinal direction along the longitudinal axis 34 within a certain scale defined by the longitudinal extension of the through groove 88, or either, the scale is controlled by the pin 58 and the characteristic slot element of the through slot.

The rotating part assembly 26 is now mounted in a ready step to be mounted in the notched lock cylinder cover 22. Referring again to FIGS. 5-10, the cylindrical portion 66 of the shank 46 on which the first clutch 56 is mounted is longitudinally inserted into the longitudinal cavity 36 of the cover 22 of the notched lock cylinder in the first end 30 along the longitudinal axis 34. The cover 44 of the retainer is disposed on the guard portion 64 of the rod 66 and in contact with the shoulder 68. The cover 44 of the retainer is received on the cover 22 of the lock cylinder with Notch and is coupled to the latter using techniques conventional joining, eg, friction coupling, staking, welding, etc., to retain the cylindrical portion 66 in the longitudinal cavity 36. The rotating part 42 is inserted into the guard portion 64 and is held in position in relation to the latter by tightening the clamping screw 48 to engage a conical cavity in a side surface of the guard portion 64. Therefore, with the rotary part assembly 26, a rotating part 42 is provided in drive coupling. with it first clutch 56 in a permanent coupling fixed in a rotating manner.

Referring to Figures 5, 9, 10, 12 and 13, the key cylinder assembly 28 includes a cylinder 100, a retainer cover 102, a second clutch 04 and a compression spring 106.

The key cylinder 100 has internal operating characteristics well known in the art and can be configured as a lock cylinder that can be locked again. For a better discussion, a description of the internal components and / or re-keying aspects of the lock cylinder 100 will not be seen in detail here.

As best illustrated in Figures 5, 9, 10, 12 and 13, e | cylinder 100 with key includes a cylinder body 108 having a terminal face end 110 and a drive end portion 112. A keyhole 1 14 configured to receive a key 116 extends longitudinally from the face end 100 of the cylinder to the portion 12 of the drive end. This portion 1 12 includes a hollow interior 118 and a pair of slots 120 diametrically opposite. There is a characteristic annular element 121 in relief located in the portion 12 of the driving end of the cylinder 100 with a key. The cylinder body 108 is configured to be longitudinally inserted in the longitudinal cavity 36 of the cover 22 of the lock cylinder with notch in the second end 32. The cover 1102 of the retainer is configured to retain the cylinder body 108 in the longitudinal cavity. 36 of the cover 22 of the lock cylinder with notch and restrict the movement of the lock body 108 along the longitudinal axis. i Referring now to FIGS. 4, 9 and 12, the key cylinder 100 further includes a spring-biased clamping bar 122 that engages in a retractable manner with a notch 124 of longitudinal clamping bar, formed in a side wall 126 of the longitudinal cavity 36 of cover 22 of the lock cylinder with notch. If there is no key or an unsuitable key (not shown) is inserted into the keyhole 114, the internal components (eg, pins and racks) of the key cylinder 100 are arranged to prevent the clamping bar 122 from being retracted out of the way. the notch 124 of the longitudinal clamping bar formed in the side wall 126 of the longitudinal cavity 36 of the cover 22 of the notched lock cylinder, thus maintaining an aségurated condition and preventing the rotation of the cylinder 100 with a key, by the use of the latter about the longitudinal axis 34. When a suitable key 116 is inserted into the keyhole 114, the internal components (e.g. zippers) of cylinder 100 with key are positioned so that clamping bar 122 can be retracted radially towards cylinder body 108, as said cylinder 100 with key rotates by use of the latter, thus establishing an open condition and allowing the rotation of cylinder 100 with key and clamping bar 122 in longitudinal cavity 36 of cover 22 of the notched lock cylinder, about the longitudinal axis.

Referring now to Figures 5 and 7-14, the second clutch 104 has a first end 128 and a second end 130. The first end 128 includes a pair of diametrically opposed tabs 132 configured to be slidably received by the slots 120. diametrically opposed located in the portion 112 of the driving end of the body 108 of the cylinder 100 with key. The first end 128 of the second clutch 104 further includes a longitudinal extension 133 extending towards the cylinder 100 with a key in the direction 95. The second clutch 104 has a hollow interior 134 extending from the second end 130 towards the first end 128. and terminates to form an internal terminal wall 136. Located at the second end 130 there is a protruding feature 138 in the form of a distinctive protruding element pair 138 diametrically opposed. The protruding feature 138 is configured to extend toward the first clutch 56. The hollow interior 134 of the second clutch 104 is configured to receive the compression spring 106.

It is assembled to the cylinder 100 with a key in the following manner. The first end 128 of the second clutch 104 is inserted into the hollow interior 118 of the driving end portion 112 of the cylinder body 108, so that the diametrically opposed tabs 132 are received in sliding manner by the diametrically opposed slots 120 located in the portion 112 of the driving end of the cylinder body 108 of the cylinder 100. The compression spring is inserted into the hollow interior 134 of the second clutch 104.

The key cylinder assembly 28 is now assembled and ready to be mounted on the cover 22 of the notched lock cylinder. The body 108 of the cylinder 100 is then keyed into the longitudinal cavity 36 of the cover 22 of the lock cylinder at the second end 32., the compression spring 106 being interposed between the inner end wall 136 of the second clutch 104 and the inner end wall 96 of the first clutch 56. The cover 102 of the retainer is received in the cover 22 of the notched lock cylinder and is coupled to the latter, for example, by friction adjustment, staking, welding, etc. for retaining the body 108 in the longitudinal cavity 36 of said cover 22 and restricting the movement of the key cylinder 100 of the assembly 28 along the longitudinal axis 34. Thus, with the key cylinder 100, the body 108 engages in drive coupling. with the second clutch 104 and the biasing force of the compression spring 106 is exerted against the second clutch 104 in the direction 95.

Once the rotating part assembly 26 is assembled, the cylinder assembly 28 with key and cam assembly 24 on cover 22 of the lock cylinder with key, the cam assembly 24 is always rotatably secured against the rotating part assembly 26 but is not rotatably secured to the assembly 28 cylinder with key.

Referring now to Figures 15A-5D, the cam assembly 24 includes a cam member 140 that is diametrically divided into a first cam portion 142 and a second cam portion 144. The first cam portion 142 is configured as a cam portion. first semi-circular portion 146 from which a cam side wall 148 having an extension tab 150 diametrically extends. The second cam portion 144 is configured as a second semi-circular portion 152 from which a cam extends. Cam side wall 154 having a cantilevered upper portion 156. This cantilevered upper portion 156 has a lower surface 158 with a groove 160 configured to receive the extension tongue 150 of the first cam portion 142.

The cam member 140 has two annular retaining grooves 162, 164 which are longitudinally spaced apart and at least one driving groove 166, for example, a pair of diametrically opposed driving grooves 166 extending longitudinally between the two annular retaining grooves 162. 164. The diametrically opposed driving grooves 166 are configured to receive in a driving manner a portion 90 of the first clutch 56, without taking into account the fact that the latter is in the neutral position 98 (see, for example, FIGS. , 4, 8 and 12), as determined by the compression spring 54 and the longitudinal extension of the through slot 88 or the first clutch 56 is displaced longitudinally from the neutral position. As such, the diametrically opposite tongues 90 of the first clutch 56 are always arranged to engage in a drive with the diametrically opposite grooves 166 of the cam member 140, that is, the first clutch 56 is always rotatably fixed to the cam assembly 24. and, thus, the rotation of the first clutch 56 will always result in a rotation of the cam assembly i. 24 around the longitudinal axis. At this time, the diametrically opposite tabs 132 of the second clutch 104 are disposed within the annular retention groove 164 of the cam member 140 and the protruding feature 138 of the second clutch 104 is not engaged in a drive with the characteristic slot element. 92 of the first clutch 56, that is, the second clutch 104 is not rotatably fixed with the first clutch 56 nor with the cam assembly 24. In the present form, the second clutch 104 does not directly engage with the cam assembly 24 On the contrary, the second clutch 104 can be selectively coupled with the first cam 56 to drive the cam assembly 24 by the key cylinder assembly 28.

It is assembled in the following manner to the cam assembly 24. The rotatable part assembly 26 and a key cylinder assembly 28 have been previously mounted on the cover 22 of the notched lock cylinder. The extension tab 150 of the first cam portion 142 is inserted into the slot 160 of the second cam portion 144, with the first semi-circular portion 146 engaged with the second semi-circular portion 152. At this time, the annular retaining groove 162 of the cam member 140 engages the corresponding annular feature 69 on the distal end 62 of the shank 46 of the rotating part assembly 26 and the annular retaining groove 164 of the cam member 140 engages a corresponding annular feature 121 in the drive end portion 112 of the key cylinder 100. Then, a retaining clip 168 slides on the outer surfaces of the first semi-circular portion 146 and the second semi-circular portion 152 to join the first cam portion 142 and the second cam portion 144 so as to form to the set 24 of cam.

Since the rotating part 42 is fixed in a rotatable manner to the rod 46, which is in turn rotatably fixed to the first clutch 56, which in turn rotatably fixes the cam assembly 24, the action of the rotation The manual of the piece 42 will always rotate the cam assembly 24 around the co-axis of rotation 34 and will therefore result in the retraction or release of the latch 18 on the notched lock 10.

Thus, with the present invention, there are two clutches, namely the first clutch 56 and the second clutch 104, which serve to rotationally drive the cam assembly 24. Although the first clutch 56 is fixed in a rotatable manner with respect to the shank 46, the first clutch 56 can slide in longitudinal directions within the scale which is controlled by the pin 58 and the through slot 88. The first clutch 56 is spring-biased in the direction 95 towards the external cylinder 100 by key, by the compression spring 54. It is placed axially to the second clutch 104 between the first clutch 56 and he external cylinder 100 with key and is always pushed in the direction 95 towards the external cylinder 100 with key by the compression spring 106. The second clutch 04 is fixed in a rotatable manner with respect to the body 108 of the cylinder 100 with wrench, but a second clutch 104 is normally pushed by the compression spring 106 out of engagement with the first clutch 56, in which case the second clutch 104 is free to rotate independent of the cam assembly 24. The force of the compression spring 106 is designed to be lower than that of the compression spring 54 in a certain predetermined proportion in order to ensure proper operation.

As illustrated in Figures 9-14, in the present form when the key 116 is inserted into the keyhole 114 of the cylinder 100 with a key, the tip of said key 116 will push against the extension 133 of the second clutch 104 and push its the second clutch 104 inwards towards the first clutch 56 in the direction 170. When the protruding characteristic element 138 of the second clutch 104 is aligned with the characteristic slot element 92 of the first clutch 56 (see FIGS. 12-14), it can completely insert the key 116, which will then completely displace the second clutch 104 to fit in shape urging the protruding feature 138 of the second clutch 104 with the slot feature 92 of the first clutch 56 and temporarily fixing the rotation between the first clutch 56 and the second clutch 104, so that both clutches 56 and 104 will rotate together; the first clutch 56 is fixed rotatably to the cam assembly 24. As such, the second clutch 104 is temporarily rotatably coupled to the cam assembly 24 through the first clutch 56. Since the key 116 is fully inserted into the cylinder 100, the latter can now rotate by rotating said key 116, which in turn rotates the cam assembly 24 to retract or launch (ie, extend) the bolt 18 over the notched lock 10.

The shank 46 of the rotating part is actuated by the compression spring 54 to allow the key 116 to be fully engaged when the protruding feature 138 of the second clutch 104 is not aligned with the characteristic slot member 92 of the first clutch 56 (see Figures 9-11), that is, by longitudinally displacing the first clutch 56 in the direction 170 that part of the cylinder 100 with a key and away from the neutral position 98 to a non-neutral position, such as when the rotating part 42 is in an orientation different from the vertical direction (position). This displacement of the first clutch 56 in the direction 170 is facilitated by the longitudinal extension of the through slot 88 and results in compression of the spring 54. Since the key 116 is completely inserted, the cylinder 100 with key can turn and eventually the characteristic protruding element 138 of the second clutch 104 will be aligned with the groove 92 of the first clutch 56 and, once aligned, said protruding feature element 138 of the second clutch will engage the groove 92 of the first clutch 56 in the axial direction 95 along the shaft 34 by decompressing the spring 54, thus returning the first clutch 56 to the neutral position 98 illustrated in FIGS. 12 and 13.

When the key 116 is withdrawn axially from the cylinder 100 with a key in the direction 95, the second clutch 104 will be separated from the first clutch 56 by the action of the thrust force exerted by the compression spring 106 in the direction 95. Now, the first clutch 56 can rotate independently of the cylinder 100 with a key, so that the rotating part 42 can rotate to activate the lock 10 with a stop even when the key cylinder 100 remains in a secured condition until the reinsertion of the key. the key.
