Description

Double-sided cylinder lock with rotary knob

Technical field

BACKGROUND OF THE INVENTION The invention relates to a two-sided cylinder lock with a rotary control knob comprising an inlet base body provided with a through inlet opening in which the inlet cylinder lock is rotatably supported by an actuator, in particular a key coupled to an axially sliding shaft; an outlet base body provided with a through outlet opening, wherein the inlet base body and the outlet base body are rigidly coupled and a rotatable thumb is disposed therebetween and the inlet opening and the outlet opening are aligned.

BACKGROUND OF THE INVENTION

The prior art patent documents solve other technical problems with other technical means for double-sided cylinder locks with rotary control knobs than those of the present invention.

For example, EP 2287423 addresses the problem of preventing unwanted manipulation of the rotary knob by means of tools pushed into the interior from outside the door, for example by a gap along the door or through an opening in the door.

A number of other documents deal with similar issues.

DE 102010022275 addresses the problem of the connection of the two opposite locking systems to the rotary thumb. In fact, it is desirable for locks of a given type to be able to rotate the rotary thumb by means of an internal locking system operated from the inside by a rotary knob independently of the external locking system operated by, for example, a key. It is particularly undesirable to rotate the locking thumb by means of the internal locking system. Therefore, a number of different couplings are provided in the prior art which allow independent locking of the locking thumb by means of an internal and external locking system and the solution according to DE 102010022275 represents one such solution.

JP 2011179268 discloses a double-sided lock with a rotary control knob, in which the rotary control knob can be locked by means of two folding blades in which recesses on the mattress platform engage. This solution represents only a partial solution of locking the rotary control knob against rotation, without the functional solution of the locking system operated by the rotary control knob from the inside of the door and without solving a closer connection to the locking system operated from the outside of the door. This publication discloses a known slip clutch that can be used to alternately connect and disconnect two axially adjacent shafts, but in general it is not clear to what purpose the clutch assembly is intended.

When using double-sided cylinder locks with rotary control knobs according to the prior art, it is not possible to prevent unwanted opening of the door from the outside with the correct key. In practice, for example, a user may forget a key in a commonly accessible location and want to prevent it from being misused in order to trick its attention even when it is present in a locked space.

None of the double-sided cylinder locks with a rotary control knob according to the prior art makes it possible to disengage the locking mechanism operated from the outside of the door by disengaging its downstream locking mechanisms.

Also, in the prior art, there is no actuating device which, by means of a rotary control knob, allows the operation of a double-sided cylinder lock with a rotary knob which enables the locking mechanism operated from the outside of the door to be disengaged.

- 13 GB 304066 B6

The end wall 77 of the oval through hole 76 is axially aligned in the double-sided cylinder lock assembly so that the oval through hole 76 allows the guide pin 42 connecting the control shaft 31 to the plug portion 71 of the sleeve 57 to pass. the shaft 20 in the full engagement position with the control coupling 36 of the control shaft 31.

At the same time, the axial alignment of the end spacer wall 77 of the oval through hole 76 can define the maximum travel length of the control shaft 31 or the rotary control knob 80 in the respective direction.

The length of the oval through hole 76 is at least such as to allow the guide pin 42, together with the control shaft 31, to be moved from the position in which the input coupling 30 on the input shaft 20 is in a fully engaged position with the control coupling 36 on the control shaft 31. a position in which the inlet coupling element 30 is in a position to completely disengage the inlet coupling element 30 with the control coupling element 36.

The pivot sleeve 57 is rotatably mounted in the outlet opening 6 of the outlet base body 5, where it is also secured against axial displacement in both directions. The outlet orifice 6 is offset at an appropriate portion of its length closer to the insertion portion 71 of the rotary bushing 57, forming an abutment surface 79 (FIG. 21) against which the end face 65 of the cylindrical base 62 of the rotary bushing 57 abuts. secured against axial displacement towards the rotary control knob 80.

On the coupling portion 63 of the swivel sleeve 57, in the double-sided cylinder lock assembly, an extension 81 is coupled to the outlet base body 5. This extension 81 is provided with a downstream outlet opening 82 of smaller diameter than the diameter of the outlet opening 6 in the outlet base body 5. By offsetting the diameters between the downstream outlet opening 82 and the outlet opening 6, an opposing abutment surface 83 (FIG. 20) is formed on the end face of the extension 81, against which the opposing adjustment surface 66 of the cylindrical base 62 of the rotatable housing 57 is supported. 57 is secured against axial displacement in the opposite direction, that is, away from the rotary knob 80.

The extension 81 is fixedly attached to the inlet base body 1 and the outlet base body 5, according to an exemplary embodiment, by means of a connecting bar 7 (FIG. 20) and connecting rivets 8.

The sleeve 57 is also secured against unwanted rotation in the outlet base body 5, which in the exemplary embodiment is such that a recess 84 (FIG. 10) is formed in the cylindrical base 62 of the sleeve 57 (FIG. 10) to enter the locking ball 85 (FIG. 9), which together with the compression spring 86 (FIG. 1) secures the pivot bushing 57 against rotation analogously to the locking ball 13 spring-loaded with the spring 14 and engaging the locking groove 16 (FIG. 2) in the carrier 9. This Thus, the locking is analogous to the prior art such that the locking ball 85 is permanently pushed by the locking spring 86 in the radial direction against the sleeve 57, and when the smooth cylindrical surface of the sleeve 57 is rotated against the locking ball 85, the locking ball 85 slides over it. . Once the recess 84 is rotated against the securing ball 85, the securing ball 85 engages therein and holds the rotary housing 57 against rotation by a force that can be overcome by rotating the rotary control knob 80.

The pivoting finger 69 is positioned entirely analogously to the prior art functional location between the input base body 1 and the output base body 5 with the extension 81 so that it is rotatable about the longitudinal axis of the double-sided cylinder lock while being secured against undesirable on both sides. axial feed.

A locking shaft 29 (FIGS. 5, 14) of the input shaft 20 is also threaded through the locking clutch 67 and the rotary thumb 69 in the assembly. The rotary thumb 69 (FIGS. 12, 13) is provided with at least one shaped surface 88 for non-rotatable engagement with the locking The rotary thumb 69 is optionally also provided with a cylindrical surface 89 for rotationally and axially displaceable connection with the connecting shaft 29 of the input shaft 20.

The threaded connecting shaft 29 of the input shaft 20 extends over parts of its outer cylindrical surface over the shape of the locking clutch 67 and therefore the threading hole 87 in the rotary thumb 69 has a shape corresponding to its cylindrical surface 89 extending through the connecting shaft 29 of the input shaft 20 and its two opposed pairs of Thus, the coupling shaft 29 can rotate freely and axially in the threaded opening 87, and the shaped surfaces 88, in cooperation with the shape of the locking clutch 67, provide a non-rotatable connection between the sleeve 57 and the pivot finger 69.

The outer shape and other elements of the pivot finger 69 correspond to the conventional shape and design of components of the same function known in the art.

The threading hole 87 extends through the axis of the annular base 90, on both sides of the threading hole 87 cylindrical shoulder 92 and 93 are connected to compensate for axial clearances and for eventual entry of adjacent components. In the exemplary embodiment, the carrier 9 partially enters the cylindrical shoulder 92 at its respective end.

Also at the periphery of the annular base 90 are cylindrical spacings with faces 94, 95 that secure the pivot thumb 69 against axial displacement in both directions such that one face 94 abuts the end face 96 of the inlet base body 1 and the other face 95 abuts against the end face 97 of the extension 81.

In the double-sided cylinder lock assembly, the plug-in portion 71 of the rotary housing half-shaft 64 protrudes from the outlet port 6 of the outlet body 5 on the side of the rotary knob 80 mounted on the plug portion 71. of the part 71 with the forward stop 72.

The rotary knob 80 (Figs. 15, 16) is designed as an ergonomically designed handrail ending in a cylindrical collar99, but its outer shape and design may be any.

The double-sided cylinder lock also includes a mechanism for shifting the control shaft 31 to the extreme positions to fully engage the input coupling 30 with the control coupling 36 and to disengage the input coupling 30 and the control coupling 36 as well as holding the control shaft 31 in the extreme positions engaging the input fastener 30 with the actuating fastener 36 and for disengaging the input fastener 30 and the actuating fastener 36. This mechanism cooperates with the compression spring 58 and the span spring 43.

- 15GB 304066 B6

The controls of the mechanism for controlling and holding the control shaft 31 are located in the rotary control knob 80, which is provided with a radial guide hole 100 for the entry of the guide pin 42 (FIGS. 15, 16, 19). The guide hole 100 extends at the beginning of the plug hole 98 and its axis lies in its axial plane and is designed on both sides. In general, however, the guide opening 100 can also be guided one side.

In the double-sided cylinder lock assembly, a guide pin 42 is inserted into the guide hole 100 in the rotary knob 80, which at the same time passes through the oval through hole 76 in the rotary housing 57 and further enters the radial connecting hole 41 formed in the control shaft 31 (FIG. 20). The guide pin 42 extends on both sides through the entire diameter of the cylindrical sleeve 99 of the rotary knob 80 mounted on the socket portion 71, the entire diameter of the socket portion 71 and the entire diameter of the pin portion 38, but may also be connected unilaterally.

By means of the guide pin 42, a fixed connection is provided between the rotary control knob 80 and the control shaft 31, and at the same time, the axially extending oval through hole 76 permits axial displacement of the rotary control knob 80 and control shaft 31 relative to the rotary housing 57 and the output body 5.

The push-in bore 98 in the rotary knob 80 is provided with at least one sliding surface 101 and at the same time the push-in portion 71 of the rotary housing 57 is provided with at least one cooperating guide surface 102 for non-rotatable axially displaceable connection with each other.

At the end of the insertion portion 71, two mirrored longitudinal planar guide surfaces 102 are provided and two corresponding mirrored planar sliding surfaces 101 are provided in the insertion opening 98, located at the sides of the insertion opening 98.

The non-rotatable connection between the rotary knob 80 and the rotary housing 57 can also be provided, for example, by a guide knob 42 in the oval through hole 76 or generally known elements, but the embodiment according to the embodiment is a more advantageous variant with conventional very small double cylinder cylinder dimensions. The rotary knob 80 is secured in the double-sided cylinder lock assembly to prevent the non-rotating connection with the rotary sleeve 57 from slipping away.

The function of securing the rotary control knob 80 against slipping out of the non-rotatable connection with the rotary housing 57 is accomplished by the end spacer wall 78 in the oval through hole 76 which defines the maximum length of the axial displacement of the guide pin 42 and thereby. this has been secured on the socket part 71 of the sleeve 57 to prevent it from slipping off the socket part 71.

The rotary control knob 80 is secured in the double-sided cylinder lock assembly against undesirable contact with the output base body 5. The rotary control knob 80 against the output face 103 of the output base body 5 prevents a stop face 73 which prevents the rotary control knob 80 from undesirable axial movement toward it. the output base body 5.

The rotary knob 80 is provided with a radial fuse opening 104 for the pin fuse 105 (FIGS. 17, 18). The fuse opening 104 is formed in the axial plane of the rotary control knob 80 behind the radial guide hole 100 for the guide pin 42 and further from the mouth of the insertion hole 98. The fuse hole 104 is connected to the insertion hole 98 and opens unilaterally on the outer wall of the rotary knob 80 and In the exemplary embodiment, the fuse opening 104 is made blind from one side, but may, for example, be made through and additionally blinded from the respective side, or another smaller (not shown) opening may be inserted into its blind bottom 106.

- 16GB 304066 B6

A cylindrical pin fuse 105 is mounted in the fuse opening 104 in the rotary control knob 80 in the double-sided cylinder lock assembly. It can exit through the opening of the fuse opening 104 from the rotary control knob 80, and is provided with an operating face 107 at its protruding end. At its opposite end, the pin fuse 105 abuts with its abutment face 108 on a compression return spring 109 which abuts with its opposite end on the blind bottom 106 of the fuse opening 104 and permanently pushes the pin fuse 105 out of the fuse opening 104, thus counteracting external pressure. The flail fuse 105 is provided with a centering pin 146. The flail fuse 105 is provided with a transverse locking groove 110 for the inlet of the forward stop 72. The locking groove 110 is provided with a bottom which forms an engagement surface 111 and a corresponding portion of the outer cylindrical surface of the pin fuse 105 The locking groove 110 and the abutment face 108 form a disengaging abutment surface 112 parallel to the engagement abutment surface 111.

In the arrangement of the cylinder lock assembly according to the first exemplary embodiment, the axial distance between the engagement surface 111 and the parallel disengagement surface 112 is the same as the distance to move the actuator 36 of the actuator shaft 31 from the fully engaged position to the fully disengaged position. 30 of the input shaft 20 and at the same time the axial distance between the stop face 73 and the end face 74 on the socket 71 of the sleeve 57 is greater than the axial distance between the engagement surface 111 and the disengagement surface 112. they are arranged one above the other in the axis of the pin fuse 105.

In the exemplary embodiment, the locking groove 110 is open on two sides and its bottom forming the engagement bearing surface 111 is flat, however, the locking groove 110 may generally be closed and its bottom forming the engaging bearing surface 111 may also be shaped.

When, in the double-sided cylinder lock assembly of the first exemplary embodiment, the engagement abutment surface 111 abuts the stop face 73 of the forward stop 72, the actuator coupling 36 of the control shaft 31 is in a fully engaged position with the input coupling member 30 of the input shaft 20.

When, in the double-sided cylinder lock assembly, the release contact surface 112 abuts against the stop face 73, the actuator connecting element 36 of the control shaft 31 is in a fully disengaged position with the input element 30 of the input shaft 20.

Generally, it is still possible to provide such a not shown arrangement of the forward stop 72 and the pin fuse 105, in which the engagement surface 111 and the disengagement surface 112 are parallel and aligned in the axis of the pin fuse 105 but one axial distance between the engagement surface 111 and the disengagement engagement the surface 112 is greater than the distance to move the control shaft 36 of the control shaft 31 from the fully engaged position to the fully disengaged position with the input shaft 30 of the input shaft 20 and the axial distance between the stop face 73 and the end face 74 on the socket 71 it is the same as the distance to move the control shaft 36 of the control shaft 31 from a fully engaged position to a fully disengaged position with the input shaft 30 of the input shaft 20.

When, in the double-sided cylinder lock assembly according to this arrangement (not shown), the disengaging surface 112 abuts the end face 74, the actuator coupling 36 of the control shaft 31 is in a position for full engagement with the input coupling element 30 of the input shaft 20.

When the disengagement surface 112 abuts the stop face 73 of the forward stop 72, the actuator 36 of the control shaft 31 is in a fully disengaged position with the input engagement element 30 of the input shaft 20.

- 17GB 304066 B6

Furthermore, it is still generally possible to depict an arrangement (not shown) in which the pin lock 105 is rotatable, not slidable. In this arrangement (not shown), the engagement bearing surface 111 and the disengaging surface 112 will be parallel but will only be aligned with respect to the pin fuse axis 105, that is, the disengaging surface 112 will not be located between the locking groove 110 and the engaging face 108 of the pin fuse 105, but will be located on the opposite side of the pin retainer 105 opposite the engagement abutment surface 111.

In general, it is also possible for a control mechanism (not shown) in the actuator to be built on an electric drive or the like.

The pin fuse 105 is further provided with a radial pin stop 113 having a contact surface 144 and the rotary knob 80 is provided with a co-operating positioning surface 114 for axially locking the pin fuse 105 in a position in which the release contact surface 112 is set against the stop face 73 and a fuse 105 to prevent it from falling out of the fuse opening 104.

The pin stop 113 of the exemplary embodiment is formed as a separate resilient pin and is disposed in a through radial stop hole 115 which is located on the release contact surface 107 of the pin fuse 105 and whose axis lies in the axial plane of the pin fuse 105. of the locking groove 109 in the pin retainer 105 so that its longitudinal axis is perpendicular to the bottom plane of the locking groove 109.

The radial pin stop 113 protrudes with one end from the stop hole 115 and its opposite end from the pin retainer 105 than the mouth of the locking groove 110.

The described pin fuse assembly 105 and radial pin stop 113 may generally be replaced by an adequate shape of the pin fuse 105.

The plug hole 98 in the rotary knob 80 is connected by a coaxial blind quadratic positioning hole 116, which is circumscribed in its longitudinal axis by two wider side positioning walls 117.

In the perpendicular direction, i.e. in the direction of the axis of the fuse opening 104, the positioning hole 116 is delimited closer to the mouth of the fuse opening 104 by a narrower top wall which forms the positioning surface 114.

The locking groove 110 in the pin retainer 105 is also provided with a lower abutment surface 118 which, when abutting the sliding surface 76 at the forward stop 72, secures the pin retainer 105 in a position in which the engagement abutment face 111 is set against the stop face 73.

The lower abutment surface 118 of the locking groove 110 engages the slide surface 75 of the forward stop 72 at the position of the pin retainer 105, in which the locking groove 110 is slid onto the forward stop 72. the forward stop 72 becomes self-locking and the pin lock 105 is locked in position.

The relative position of the positioning surface 114, the sliding surface 75 of the advance stop 72, the lower abutment surfaces 118 of the locking groove 110 and the radial pin stop 113 are such that when the radial pin stop 113 is supported against the positioning surface 114 face 73 of the forward stop 72.

The second narrower lower abutment wall 119 of the positioning hole 116 defines or may limit the movement of the pin fuse 105 with the radial pin stop 113 in the respective direction so as not to overload the compression spring 109 or insert the pin fuse too deeply. 105 into the fuse opening 104.

The side contact surfaces 145 of the radial pin stop 113 of the pin fuse 105, in conjunction with the side positioning walls 117 of the positioning hole 116, secures the pin fuse 105 against undesired rotation about its longitudinal axis from the position in which the engagement abutment 111 or disengagement abutment 112 in the double-sided cylinder lock assembly against the stop face 73 or end face 74 of the plug-in portion 71 of the rotary sleeve 57.

The pin fuse 105 has a cylinder boil. However, the pin fuse 105 may, for example, generally be a shaped pin of any cross-section and the fuse opening 104 may be adapted to its shape, and the anti-twist locking may thus be in the form of the pin fuse 105 and the corresponding shape of the fuse opening 104.

The locking groove 110 in the pin retainer 105 and the advance stop 72 are adapted to each other in shape, size and arrangement in the double-sided cylinder lock assembly so that the locking groove 110 can slide onto the advance stop 72 and contact the stop face 73 with the engagement surface. 111.

The rotary control knob 80 is guided in its axial sliding motion by the inner cylindrical sliding surface 120 in the insertion hole 98 over the outer cylindrical guide surface 121 of the insertion part 71 so that the locking groove 110 of the pin retainer 105 can correctly slide onto the forward stop 72.

In the perpendicular direction, in addition, two mirror-guided guide surfaces 102 can be held by the rotary control knob 80 on the insertion part 71 of the rotary housing 57, along which the inner sliding surfaces 101 are guided in the insertion opening 98 of the rotary control knob 80.

A second embodiment of the invention of FIGS. 22 to 31 is a double-sided cylinder lock with a rotary knob 80 with a function to disengage its downstream locking mechanisms with yet another additional function to mechanically lock the rotary control knob 80 when adjusted to disengage the downstream locking mechanisms.

The assembly and design of the two-sided cylinder lock elements, hereinafter referred to as the "two-sided cylinder lock with rotary knob lock" according to the second exemplary embodiment, are substantially identical to the assembly and design of the two-sided cylinder lock elements of the first exemplary embodiment and all considerations and claims to the first embodiment, it can also be applied to the second embodiment.

In addition, the locking pin 122 described below (FIG. 22) is used in the assembly.

Only the output base body 123, the pivot bush 124 (FIGS. 25, 26, 27), and the actuator shaft 125 (FIGS. 23, 24) differ from each other in the assembly of the assembly by the adjustments described below to align and interact with the locking pin 122.

In a double-sided cylinder lock with a locking knob according to the second exemplary embodiment, the outlet opening 126 in the outlet base body 123 must be provided with at least one offset to form a support surface 127.

The rotatable housing 124 is provided with at least one respective cooperating adjusting surface 128 which is formed by offsetting the diameter of its half-axis 129 from the peripheral surface 130.

The functions of the abutment surface 127 in the outlet base body 123 and the adjustment surface 128 on the rotatable housing 124 may be analogous to those of the abutment surface 79 and the front adjustment surface 65 according to the invention.

Thus, these surfaces can also serve to secure the rotatable housing 124 against axial displacement in the outlet base body 123 (FIG. 31).

A further radial locking groove 131 (FIGS. 22, 25, 26, 27) is provided in the circumferential surface 130 of the rotary bushing 124 (FIGS. 22, 25, 26, 27), which extends through the adjusting surface 128 and extends with its end portion 132 up to the axle 129. The blocking groove 131 is parallel to the oval through hole 76 provided in the half-axis 129 of the rotary bushing 124 analogously to the oval through hole 76 of the first exemplary embodiment. The locking groove 131 may be either one-sided or may extend through the entire diameter of the peripheral surface 130.

At least one locking recess 135 (FIGS. 29, 30) is also provided in the abutment surface 127 in the outlet base body 123 (FIGS. 29, 30), dimensionally aligned with the locking groove 131 when the rotary sleeve 124 and the rotary thumb 69 are rotatably connected to the door locking position. or other building fillings. The locking recess 135 is terminated in the axial direction by a locking surface 136 and delimited on the sides by side walls 143.

If the locking groove 131 is formed on one side, then one locking recess 135 is provided against it in the outlet base body 123.

If the locking groove 131 extends through the entire diameter of the half-axle 129, two opposing locking recesses 135 may also be provided against it in the outlet base body 123, as in the exemplary embodiment.

The control shaft 125 is provided with a further radial pin hole 137 in which the locking pin 122. is inserted. The pin hole 137 is provided in the coupling portion 138 of the control shaft 125. The pin hole 137 may be either one-sided or extend through the entire diameter of the respective portion of the control shaft 125. .

The locking pin 122 is inserted in the pin hole 137 such that it protrudes at least one of its locking end 139 from the pin hole 137 in such a length that it extends through this locking end 139 into the locking groove 131 in the rotary bushing 124. 135. In the illustrated embodiment, the locking pin 122 protrudes from the pin bore 137 on both sides with its two locking ends 139. The locking pin 122 is cylindrical in shape and has a partially prismatic shape at both locking ends 139 and has a locking surface 140 (FIG. 30).

In the pin hole 137, the locking pin 122 is fixedly secured and secured against axial displacement and possibly against rotation, for example by pressing.

The axial arrangement of the end wall 133 of the locking groove 131 in the double-sided cylinder lock assembly is such that the locking groove 131 allows the locking end 139 of the locking pin 122 to enter correctly in the position of the control shaft 125 in which its operating coupling 36 is in the full engagement position. at the same time, the locking surface 140 (FIG. 30) of the locking end 139 must also be at least as close to the support surface 127 in the axial direction as is necessary to completely disengage the control connecting member 36 and the input connecting member 30 in the assembly double-sided cylinder lock.

The distance of the end wall 134 from the end wall 133 of the locking groove 131 and the distance of the locking surface 136 of the locking recess 135 from the end wall 133 of the locking groove 131 is such that the end wall 134 and the locking surface 136 allow the locking pin 122 to move. the engagement member 36 in full engagement position with the inlet engagement member 30 to a position in which the actuator engagement member 36 is in a fully disengaged position with the inlet engagement member 30 and the locking end 139 of the locking pin 122 enters the block recess 135 to a depth such that the rotary housing 124 is secured against rotation.

The length of the spacing pin 44, the dimensions of the spacing spring 43, and the axial dimensions and arrangement of the input centering portion 46 of the input shaft 20 and the actuating centering portion 47 of the control shaft 125 according to the second exemplary embodiment are such that while engaging the engaging member 30 and the engaging member 36 in the double-sided cylinder lock assembly and engaging the locking end 139 of the locking bolt 122 to firmly secure the pivot bushing 124 against rotation. the pin 44 is permanently inserted with both ends in the input centering portion 46 of the input shaft 20 and the actuating centering portion 47 of the control shaft 125.

The distance between the support surface 59 of the rotary housing 124 and the support surface 60 of the control shaft 125 in the double-sided cylinder lock assembly is in the position of the control shaft 125 when its control coupling 36 is in full engagement with the input coupling element 30 of the input shaft 20 at least equal to the distance required to move the actuator 36 from a full engagement position with the inlet connector 30 to a fully disengaged position with the inlet connector 30 and to engage the locking end 139 of the locking pin 122 to firmly secure the pivot housing 124 against rotation plus the length required to accommodate the preloaded compression spring 58.

Securing the rotary control knob 80 against slipping of the non-rotatable connection with the rotary bushing 124 fills the locking surface 136 of the locking recess 135, which defines the maximum length of the axial displacement of the locking pin 122 and hence the control shaft 125 and the rotary control knob 80 connected thereto in the respective direction. to secure the rotary knob 80 on the socket portion 71 of the shaft 64 of the rotary housing 124 to prevent it from slipping out of the socket portion 71.

The double-sided cylinder lock according to the first and second exemplary embodiments allows the input shaft 20 to be moved to one of the two extreme positions, i.e. to the full engagement position with the control shaft 31 and to the fully disengaged position with the control shaft 31. secure the shaft 20 against reverse movement.

Also, the control shaft 31 can be moved in a two-sided cylinder lock to one of the two extreme positions, that is, to the full engagement position with the input shaft 20 and to the fully disengaged position with the input shaft 20, Secure the positions against reverse.

If both the input shaft 20 and the control shaft 31 are both set to engagement positions, the input coupling 30 and the operating coupling 36 may engage and a non-rotatable connection between the input shaft 20 and the control shaft 31 may occur. it is then desirable that both the input connecting member 30 and the operating connecting member 36 be simultaneously in their extreme positions for complete engagement to provide a reliable non-rotatable connection.

If at least the input shaft 20, or at least the control shaft 31, is set to its respective disengagement position, then the input coupling 30 and the control coupling 36 cannot engage and a non-rotatable connection between the input shaft 20 and the control shaft 31 For proper operation of the double-sided cylinder lock, it is desirable that both the inlet connection member 30 and the control connection member 36 be simultaneously in their extreme positions for complete disconnection for reliable disconnection.

When operating the double-sided cylinder lock according to the first and second exemplary embodiments by means of the rotary control knob 80, its rotational movement is in the locking direction and

The unlocking is transmitted via the sliding surface 101 in the rotary control knob 80 and the guide surface 102 on the insertion part 71 of the axle 64 of the rotary housing 57, which provides a non-rotatable connection between the rotary control knob 80 and the rotary housing 57, to the rotary housing 57 and the rotary movement 69 is further transmitted by a locking clutch 67 to the pivot thumb 69. The pivot thumb 69 further acts in a manner known per se on the unlocking elements for unlocking or locking the door or other aperture.

Upon rotation of the rotary control knob 80, the control shaft 31 rotates with it and with the rotary housing 57 to which it is non-rotatably connected by means of a guide pin 42.

If the control shaft 31 were non-rotatably coupled to the input shaft 20 during this rotational movement, then the input shaft 20 could block the rotational movement of the control shaft 31, since the input shaft 20 is coupled to the input cylinder lock 3 and is locked against rotation with it. if the inlet cylinder lock 3 is not unlocked with the appropriate key.

If the control shaft 31 could not be rotated, the rotary control knob 80 could not be rotated.

However, if the end portion 28 of the shaft 4 does not exert pressure on the contact face 27 of the input shaft head 19, the input shaft 20 is permanently pushed away from the control shaft 31 by the compression spring 43 and the spacing pin 44 so that its input coupling 30 is spaced axially. out of the engagement position 36 to its fully disengaged position with the engagement member 36. This situation corresponds, for example, to the situation where the shaft key 4 (not shown) is completely removed from the inlet cylinder lock 3. Regardless of whether the engagement link the element 36 in its fully engaged end position, when the input coupling element 30 is in the fully disengaged position, no engagement between the input shaft 20 and the control shaft 31 can occur.

Thus, if the input shaft 20 and the control shaft 31 are not connected, then the input cylinder lock 3 and the locking mechanism formed by the elements connected to the rotary control knob 80 are disengaged, the input shaft 20 does not prevent the rotational movement of the control shaft 31. they can rotate it. Thus, the rotary thumb knob 80 can be easily operated in the manner described above in the double-sided cylinder lock with the stem 4 removed.

With the independent rotational movements between the control shaft 31 and the input shaft 20, the span spring 43 and the spacing pin 44 freely rotate in the input centering hole 45 of the input shaft 20 and in the control centering hole 48 of the control shaft 31, thus the input shaft 20 does not prevent.

When inserting the shaft key 4 into the lock, or inserting the shaft 4 into the fully retracted position independently of the movement of a key (not shown), the end portion 28 of the shaft 4 first engages the contact face 27 of the input shaft head 19. correspondingly, the end portion 28 exerts pressure on the contact face 27 and the input shaft 20 is moved axially to this position to engage its input coupling 30 with the control coupling 36 of the control shaft 31. Upon complete insertion of the stem 4, the input coupling the input shaft 20 is pushed into the end position for full engagement with the control coupling 36 of the control shaft 31. In this full engagement end position, the input shaft 20 with its input coupling 30 is fully retracted by the shaft 4 in the respective axial direction .

The rotary movement of the key (not shown) is then transmitted in a known manner from the inlet cylinder lock 3 to the carrier 9, and further through the carrier element 23 of the carrier 9 and the engagement element 24 on the input shaft 20 which provide non-rotatable connection between the carrier 9 and the input shaft 20 to the input shaft. 20 May

However, the input shaft 20 in the cylinder lock assembly of the first and second exemplary embodiments is not itself adapted to transmit the rotary motion to the rotary thumb 69, nor is it permanently connected to any associated rotational movement elements to the rotary thumb 69. To transmit the rotational motion from the input shaft 20 the rotary thumb 69 can only occur when the two-sided cylinder lock is set, in which the input coupling element 30 of the input shaft 20 is engaged with the control coupling element 36 of the control shaft 31 and the input shaft 20 is thus connected by a non-rotatable coupling due to the non-rotatable connection between the input shaft 20 and the control shaft 31, the rotational movement can be transmitted from the input shaft 20 to the control shaft 31.

If, after insertion of the input shaft member 30 of the input shaft 20 into the end position for full engagement with the control connector 36 of the control shaft 31, the rotational movement generated by a shaft key 4 (not shown) is transferred to the rotary thumb 69. is set to disengage its downstream locking mechanisms, or is set to disengage its locking mechanisms.

If the double-sided cylinder lock is set to disengage its downstream locking mechanisms, then the control shaft 31 and its actuating member 36 is set and held out of position for full engagement with the input engagement member in the extreme position to fully disengage the actuating member 36. In this setting of the double-sided cylinder lock, the input coupling element 30 of the input shaft 20 may be slid into the end position for full engagement with the control coupling element 36 of the control shaft 31, but to engage between the input coupling element 30 and the control coupling element 36 cannot occur.

If the input coupling element 30 of the input shaft 20 is not engaged with the control coupling element 36 of the control shaft 31 and the input shaft 20 is therefore not rotatably connected to the control shaft 31, then the input shaft 20 simply rotates freely in the cylindrical receiving bore 56 bushing 57 and hence also free rotation of the input shaft 20 in the thrust hole 87 of the pivot finger 69.

Without engaging the fastener 30 with the actuating fastener 36, the rotary thumb 69 will not be carried in the direction of the key-driven rotary motion, and hence the rotary thumb 69 needed to unlock or lock the door by the key.

When the double-sided cylinder lock is configured to engage its downstream locking mechanisms, the control shaft 31, and with it, its control coupling 36, is set and held in position for full engagement with the input coupling element 30 of the input shaft 20.

If, at this setting of the double-sided cylinder lock, the input coupling element 30 of the input shaft 20 is slid into position for engagement with the control coupling element 36 of the control shaft 31, the engagement between the input coupling element 30 and the control coupling 36 may occur.

If the input coupling element 30 and the operating coupling element 36 have been correctly angled for engagement with the control shaft 31 before sliding the input shaft 20 into the engagement position, simply sliding the input shaft 20 into the full engagement position with the control shaft 31 will fully engage between an input coupling element 30 and a control coupling element 36 and to form a non-rotatable connection between the input shaft 20 and the control shaft 31

If the input coupling member 30 and the operating coupling member 36 have not been correctly angled for engagement with the control shaft 31 before sliding the input shaft 20 into engagement position 31, contact between the input end face 33 will first occur when sliding the input shaft 20 into the full engagement position the input shaft 20 and the control end face 40

304066 B6 (FIG. 8) of the control shaft 31 and the input shaft 20 pushed by the shaft 4 push the control shaft 31 out of the fully engaged position against the action of the compression spring 58. Upon subsequent rotation of the shaft 4, the input shaft 20 is rotated and by this rotation the input coupling element 30 of the input shaft 20 is angularly set relative to the control coupling element 36 of the non-rotating control shaft 31. Once the angular adjustment of the input coupling element 30 relative to the control coupling element 36 has occurred, the actuating shaft 31 engages under the full spring engagement with the compression spring 58 and engages the control shaft 31 with the input shaft 20 and forms a non-rotatable connection therebetween.

Upon engagement of the control shaft 31 with the input shaft 20, the rotational movement from the input shaft 20 to the control shaft 31 is transmitted. From the control shaft, the rotational movement is then transmitted to the rotary thumb 69 as described above.

Thus, the operation of the double-sided cylinder lock according to the first and second exemplary embodiments by means of a key (not shown) can only occur if the double-sided cylinder lock is configured to connect with its downstream locking mechanisms.

Operation of the double-sided cylinder lock by means of the rotary control knob 80 can then occur whenever the double-sided cylinder lock is set to disengage with its associated locking mechanisms.

If the double-sided cylinder lock is set to engage with its downstream locking mechanisms, then the rotary knob 80 can be operated only when the shaft 4 is not engaged in the double-sided cylinder lock at a depth at which it would move the input shaft 20 to the engaging position with a control shaft 31, which in practice corresponds to a situation where the key is not inserted at all or deep enough. Thus, when the key is retracted to the stop position, the input shaft 20 moves to both sides of the insert. On the key side, however, the mechanism is unlocked, i.e., locked by the anti-torsion lock, i.e. the head 19 moves the axis into engagement with position 31 - the system is not unlocked. Unlocking occurs after turning the key by 90 °.

When the actuator shaft 31 is moved to its full engagement and fully disengaged positions with the input shaft 20 via the actuator shaft adjustment mechanism 31 of the first exemplary embodiment, when adjusting the double-sided cylinder lock to engage the locking mechanisms, the pin fuse 105 is adjusted such that the locking groove 110 in the pin retainer 105 is slid onto the forward stop 72 and the engagement surface 111 in the locking groove U0 contacts the stop face 73. In this setting, the mechanism is held by a compression spring 58 that pushes the control shaft 31 and associated elements and thereby also retains the sliding of the locking groove 110 on the forward stop 72 and presses the engagement surface 111 onto the stop face 73.

Due to the shape of the locking groove 110 and the advance stop 72 and also due to the additional pressure being applied to the pin retainer 105 by a compression spring 109 which presses the contact surface 118 of the locking groove 110 onto the sliding surface 75 of the advance stop 72 between the locking pin 105 and the forward stop 72 self-locking.

When the engagement surface 111 on the pin fuse 105 is pushed against the stop face 73 in the manner described, the rotary knob 80, which is connected to the pin fuse 105, holds the control shaft 31 by means of a guide pin 42 in its extreme position for full engagement of the control coupling 36 with input connecting element 30.

From adjusting the double-sided cylinder lock to engage the locking mechanisms, it is possible to move to the mechanism for disengaging the locking mechanisms by axially pulling the rotary knob 80 out of the lock, ie out of engagement between the coupling elements of the input shaft 20 and the control shaft 31 until locking groove 110

304066 B6 moves out of the forward stop 73. By means of the compression return spring 109, the pin fuse 105 is then ejected from the fuse opening 104 in the rotary knob 80, the locking groove 110 moves away from the forward stop 72 and against the stop face 73 of the forward stop 72. adjusts the release contact surface 112 of the pin fuse 105.

In this position, the pin retainer 105 retains a radial pin stop 113 that abuts against the positioning surface 114.

When the rotary knob 80 is released in the axial direction, the control shaft 31 is then pushed by the compression spring 58 towards the engagement and the disengagement surface 112 is pressed against the stop face 73 of the forward stop 72. At the same time the radial pin stop 113 prevents pivoting of the pin lock 105 by leaning on the lateral positioning wall 117 of the positioning hole 116 in the rotary control knob 80.

When the disengagement surface 112 on the pin fuse 105 is pushed against the stop face 73 in the manner described, then the rotary knob 80, which is connected to the pin fuse 105, holds the control shaft 31 by means of a guide pin 42 in its extreme position to fully open the control coupling 36 with input connecting element 30.

In order to adjust the double-sided cylinder lock to reconnect the locking mechanisms, it is necessary to press the pin fuse 105 by pressing on its control face 107 against the action of the pressure return spring 109 towards the inside of the fuse opening 104 in the rotary control knob 80.

If the rotary knob 80 is released in the axial direction and the pin lock 50 is pushed in such a way that the locking groove 110 is set against the forward stop 72 so that it can be slid onto the forward stop 72, it is caused by a compression spring 58 to slide the locking groove 110 onto the forward stop 72 and to move the rotary control knob 80 and the control shaft 31 accordingly to the desired position for full engagement with the input shaft 20.

In addition, if the double-sided cylinder lock has an adjustment for the mechanical locking function of the rotary knob 80 when adjusted to disengage the adjacent locking mechanisms of the second exemplary embodiment, then in the above-described handling operation setting the mechanism for disengaging the locking mechanisms, with the correct angular adjustment and the described axial extension of the rotary knob 80, the locking ends 139 of the locking pin 122 enter the locking recess 135 provided in the output base body 5. Correct angular adjustment of the rotary knob 80 to engage the locking ends 139 in the locking recess 135 corresponds to the angle of rotation of the actuating shaft 125 at which the locking pin 122 comes against the locking recess 135 .

Thus, for this correct angular adjustment, the rotary control knob 80 must also be rotated to the appropriate position either before or during its axial extension. The locking pin 122 is positioned against the counterbore recess 135 when the rotary knob 80 is set to the vertical position with the mouth of the fuse opening 104 at the top of the rotary knob 80. This embodiment is particularly advantageous because this position is indicated by a locking ball 85 engaging the recess 85 in the rotary housing 124, and therefore it is possible to achieve a correct angular adjustment of the rotary control knob 80 to enter the locking ends 139 into the recess 135 before being pulled in the axial direction.

Manipulation of the rotary control knob 80 to move from the double-sided cylinder lock setting to engage the locking mechanisms to adjust the mechanism to disengage the locking mechanisms and lock the control knob 80 of the cylinder lock according to the second exemplary embodiment thus assumes that the rotary control knob 80 first rotates to the desired position for adjusting the locking pin 122 against the locking recess 135 a

Only then will it be axially pulled out of engagement between the input shaft 20 and the control shaft 125. This withdrawal of the rotary knob 80 will both pull the control shaft 125 out of the engagement position with the input shaft 20 and retract the lock. pin 122 into the locking recess 135.

By locking the disengagement surface 112 of the pin retainer 105 against the stop face 73 of the forward stop 72 by the compression spring 58, the locking pin 122 is then held in the locking recess 135.

The side walls 143 of the locking recess 135 in the outlet base body 123 then lock the locking pin 122 against rotation in both senses. The locked blocking pin 122 then also locks the control shaft 125 and the rotary knob 80 to prevent rotation, by means of which it is not possible to perform a rotary movement to control the associated elements including the rotary thumb 69 and thus not to unlock the door or other building filler.

The double-sided cylinder lock, which according to the second exemplary embodiment is configured to disengage the locking mechanisms and at the same time its rotary control knob 80 is mechanically locked against rotation, can be reset to engage the locking mechanisms by the same handling as the double-sided cylinder lock without added functionality to mechanically lock the rotary a knob 80 according to a first exemplary embodiment.

Thus, to adjust the double-sided cylinder lock, it is sufficient to depress the pin lock 105 and leave the rotary control knob 80 released for axial translational movement. Upon respective axial movement of the rotary control knob 80 and the control shaft 125 towards the engagement, the locking pin 122 simultaneously jumps out of the locking recess 135 and the rotary control knob 80 is released for rotational movement.

In the case of the double-sided cylinder lock according to the second exemplary embodiment, it is still possible to make use of such a setting in which the locking mechanisms are disengaged but the rotary control knob 80 does not lock against rotation. Such a mechanism adjustment is possible when the rotary knob 80 is axially pulled only to a distance such that the actuator 36 moves to a fully disengaged position with the input connector 30, but the locking end 139 of the locking pin 122 does not enter the locking recess 135.

This mechanism aligns the engagement surface 111 from the stop face 73 of the advance stop 72, but does not fully extend the locking groove 110 of the pin retainer 105 in the rotary knob 80 from the advanced stop 72 and the advanced stop 72 remains partially engaged with the locking groove. Thus, the pin fuse 105 remains retained in the fuse opening 104 at this setting. The fact that the rotary control knob 80 can be rotated freely and at the same time the position of the pin fuse 105 still inserted in the fuse opening 104 indicates the user is rotatable the knob 80 is axially shifted just to the position for adjusting the double-sided cylinder lock according to the second exemplary embodiment to disengage the locking mechanisms without locking the rotary knob 80. In this position, the rotary knob 80 can be rotated t, wherein the control shaft 125 cannot be undesirably locked against rotation by a possibly blocked input shaft 20.

In the axial position for adjusting the double-sided cylinder lock to open the locking mechanisms without locking the rotary knob 80, it must be held axially by an external force against the force of the compression spring 58. of the rotary control knob 80 is axially released, then the control shaft 125 will be pushed by the compression spring 58 into a position for full engagement with the input shaft 20.

-26EN 304066 B6

Conversely, if the rotary control knob 80 is axially held and properly angled at this double-sided cylinder lock to disengage the locking mechanisms without locking, then by exerting a greater external axial force, it may be moved to the position described above for fully disengaging the control shaft 125 and the coupling shaft 20 and locking the rotary control knob 80 against rotation.

With the rotary control knob 80 of the two-sided locks of the first and second exemplary embodiments, the two-sided cylinder locks can be adjusted to engage and disengage the associated locking mechanisms even when the input shaft 20 is slid into engagement or full engagement with the control shaft 31. With such an adjustment of the input shaft 20, during adjustment of the double-sided cylinder lock for connecting the follow-up mechanisms, the compression spring 58 moves the control shaft 31, 125 only to a position where contact between the input end face 33 of the input shaft 20 and the control end face 40 The locking groove 110 is pushed onto the forward stop 72, but the engagement surface 111 is not pushed onto the stop face 73. However, the pin retainer 105 remains retained by the respective part of the forward stop 72 at the end. desired position for the two-sided cylinder lock for locking mechanisms related links.
