Description

The invention relates to a locking bolt system,
comprising a locking bolt arrangement with a locking bolt, which can be moved in a bolt sleeve along a bolt axis, and in particular is held captive,
wherein the locking bolt is preloaded into an extended position by means of spring force, in which the locking bolt protrudes with a front bolt tip from the bolt sleeve, and the locking bolt can be retracted against the spring force into a retracted position,
wherein a bolt external thread is formed at a rear end of the locking bolt,
wherein at least at a rear end of the bolt sleeve a bolt sleeve external thread is formed,
and further comprising an actuation arrangement comprising a Bowden cable.

Such a locking bolt system is known from the product data sheet “K0345 locking bolt without collar” from Heinrich Kipp Werk KG, Sulz a.N., DE, as of 9.2019.

Locking bolts can be used to secure components against lateral forces. A bolt sleeve is typically fastened in a first component, for example screwed in, and engages with a locking bolt that can be moved in the bolt sleeve in the extended position with a front bolt tip in a second component. As a result, the locking bolt blocks a movement of the second component relative to the first component transversely to the direction of movement of the locking bolt.

In the case of conventional locking bolts, the locking bolt can be retracted into the bolt sleeve against a spring force by means of a handle part which is fastened to the locking bolt, in order to release the second component.

In some application situations, however, components that are difficult to access manually must be secured against each other, in particular for manual access to a handle part that is arranged directly on the locking bolt.

In the product data sheet “K0345 locking bolt without collar” given above, a locking bolt has become known in which the locking bolt protrudes from the bolt sleeve at both ends. At the rear end of the locking bolt there is an external bolt thread onto which a handle part can be screwed. It is also proposed there to actuate the locking bolt by means of a pneumatic cylinder, or to set up remote actuation via a Bowden cable. Details on setting up the Bowden cable are not given.

Object of the invention

The object of the invention is to set up a locking bolt in a simple and inexpensive manner for remote actuation via a Bowden cable with high reliability and high level of protection against injury.

Brief description of the invention

This object is achieved according to the invention by a locking bolt system of the type mentioned at the beginning, which is characterized in that
that the actuation arrangement furthermore comprises an adapter sleeve and a union sleeve,
that a front coupling body of a core of the Bowden cable is hooked into the adapter sleeve, which is screwed onto the bolt's external thread with an adapter sleeve internal thread,
that the union sleeve engages over the adapter sleeve and is screwed onto the bolt sleeve external thread with a union sleeve internal thread, so that the adapter sleeve can be moved together with the locking bolt in an interior space of the union sleeve,
and that the cap sleeve directly or indirectly forms a first abutment for a front stop end of a Bowden cable sheath of the Bowden cable.

According to the invention it is provided to use an adapter sleeve and a union sleeve for coupling the locking bolt arrangement with the Bowden cable. These can be fastened to the locking bolt arrangement in a simple manner via internal threads, so that a conventional, inexpensive locking bolt arrangement can be used for the locking bolt system according to the invention.

The front coupling body, which is attached to the front end of the core of the Bowden cable, is hooked into the adapter sleeve (for example by threading the core through or sliding it into a slot from the side) so that the front coupling body engages behind the adapter sleeve. The adapter sleeve can then be screwed in a simple manner onto the rear end of the locking bolt at its bolt external thread, and is thereby rigidly connected to the locking bolt. As a result, the core of the Bowden cable is still connected to the locking pin in a tensile manner, and the core can transmit force to the locking pin.

The adapter sleeve, in turn, is overlapped by the cap sleeve; the union sleeve is screwed onto the outer thread of the bolt sleeve at the rear end of the bolt sleeve. This will be the moving parts arranged at the rear when actuated relative to the bolt sleeve, i.e. the locking bolt and the adapter sleeve, are covered and thus secured against contamination and generally against blocking by foreign parts and against the risk of injury. At the same time, the sleeve directly or indirectly forms the abutment for the front stop end of the Bowden cable sheath. The union sleeve is rigidly connected to the bolt sleeve through its screw connection, so that the Bowden cable sleeve mounted on the sleeve sleeve via the first abutment is positioned in a defined manner opposite the bolt sleeve, and a force transmission between the Bowden cable sleeve and the bolt sleeve mediated by the first Abutment can be done.

The locking pin arrangement can then be reliably operated remotely via the Bowden cable, even if the locking pin arrangement or a front part of the actuating arrangement at the front end of the Bowden cable is difficult or impossible to access (in particular manually). It is sufficient that a rear partial area of the actuation arrangement at the rear end of the Bowden cable is easily accessible (in particular manually).

Typically, another bolt sleeve external thread is formed at the front end of the bolt sleeve. A key surface, for example a hexagon, can be formed between the bolt sleeve external thread and the further bolt sleeve external thread. The bolt sleeve can also have a continuous external thread from the front end to the rear end. A nut, such as a hexagon nut, can be screwed onto the external thread or further external threads; the nut can be used to brace the bolt sleeve against a structure (component) into which the bolt sleeve is screwed.

Preferred embodiments of the invention

In a preferred embodiment of the locking bolt system according to the invention, it is provided that the adapter sleeve has an adapter sleeve bore on an adapter sleeve base facing away from an insertion opening of the adapter sleeve internal thread, and that a maximum diameter of the front coupling body of the core is smaller is as an inner diameter of the adapter sleeve internal thread. During assembly, the core is threaded through the adapter sleeve bore; the front coupling body fits through the insertion opening, but not through the adapter sleeve bore and thus engages behind the adapter sleeve base. This attachment of the front coupling body is particularly reliable in use and easy to assemble. Alternatively, the sleeve can also be provided with a (lateral) slot, via which the front coupling body can be hooked into the adapter sleeve without threading the core; in this case, the encompassing union sleeve typically secures the front coupling body against threading out of the adapter sleeve.

An embodiment is also advantageous which provides that a recess is formed at a rear end of the cap sleeve to form the first abutment, into which the Bowden cable sleeve is inserted and in which the Bowden cable sleeve rests against a recess base, and that the recess base has a recess bore to the interior of the cap sleeve, the core of the Bowden cable being guided through the recess bore. This is also particularly reliable in use and easy to assemble. During assembly, the core is threaded through the recess bore of the union sleeve. Alternatively, the cap sleeve can also be provided with a (lateral) slot in the area of the first abutment, via which the Bowden cable can be inserted into the recess and the cap sleeve without threading the core. As an alternative, instead of forming the first abutment in the union sleeve, a coupling (such as a thread) to an axially adjustable abutment component (such as a cup screw) can be provided, which forms the first abutment for the Bowden cable.

An embodiment is preferred in which the front coupling body is designed with a coupling ball, in particular wherein the coupling ball is irreversibly attached to the core. The coupling ball easily allows twisting of the Bowden cable with respect to the adapter sleeve, which makes the actuation of the locking bolt arrangement via the Bowden cable more flexible and more reliable. The irreversible fastening can be set up particularly reliably and mechanically robust.

Versions with handle and handle sleeve

In a particularly preferred embodiment, it is provided that the actuation arrangement further comprises a handle and a handle sleeve, the handle in the handle sleeve being movable between a retracted position and an extended position along a handle axis, and in particular being held captive that the handle forms a coupling stop that is engaged behind by a rear coupling body of the core of the Bowden cable, and that the handle sleeve directly or indirectly forms a second abutment for a rear stop end of the Bowden cable casing of the Bowden cable. The handle and the handle sleeve can be used to actuate the locking bolt Arrangement away from this can easily be done. Typically, the handle sleeve is installed in a larger, mostly stationary structure, and the handle is operated manually. The retracted position of the handle includes the extended position of the locking pin, into which the locking pin is pretensioned by means of spring force. The retracted position of the locking pin belongs to the extended position of the handle. The formation of the core with a rear coupling body, which engages behind a coupling stop of the handle body, simplifies assembly and, if necessary, facilitates replacement of the Bowden cable. As an alternative to the coupling stop and the rear coupling body, the core can also be fastened directly to the handle, for example by clamping. In general, it is sufficient within the scope of the invention if the rear end of the core is attached to the handle in a tensile manner. The handle piece and the handle piece sleeve are also referred to together as a handle piece arrangement.

In a preferred further development of this embodiment, the handle sleeve is provided with a handle sleeve external thread, in particular wherein the handle sleeve external thread extends away from a front end of the handle sleeve facing away from the handle. With the handle sleeve external thread, the handle sleeve can be fastened in a simple manner in a (mostly stationary) structure, so that the handle can easily be manually operated with one hand by pulling. The screwed-in grip sleeve can be secured with a lock nut if necessary or desired. In addition, a wrench surface, for example a hexagon, is preferably formed on the handle sleeve in order to tighten the screw connection of the handle sleeve in the structure.

Preference is also given to further training that provides
that the handle sleeve forms a handle sleeve internal thread at its front end facing away from the handle, into which an abutment screw with an external screw thread is screwed,
that the abutment screw forms a cup at its front end facing away from the external screw thread to form the second abutment into which the Bowden cable sleeve is inserted and in which the Bowden cable sleeve rests on a cup base of the cup,
and that the abutment screw is designed with an axial screw channel which runs through the cup base and the area of the screw external thread, the core of the Bowden cable being guided through the screw channel. The abutment screw can be used to easily adapt the length of the core (or the distance between the front coupling body and the rear coupling body on the core) and the length of the Bowden cable sleeve, and in particular the Bowden cable by changing the screw-in depth (adjustment position ) the abutment screw can be clamped into the grip sleeve.

In an embodiment of this development, a lock nut is advantageously arranged on the screw external thread, with which the abutment screw can be braced against the grip sleeve. This secures the adjustment position of the abutment screw in a simple manner.

It is also advantageously provided in one embodiment of the above development that the handle piece forms an axial recess at a front end that is inserted into the handle piece sleeve, the inner diameter of which is greater than the outer diameter of the external screw thread. As a result, the abutment screw can engage in the handle in the retracted position of the handle, whereby a compact structure of the handle arrangement can be achieved.

It is also advantageously provided in one embodiment of the above development that the handle sleeve comprises a reducing ring which is pressed into the rest of the handle sleeve at the front end of the handle sleeve and in which the handle sleeve internal thread is formed. This makes it possible, when assembling the handle assembly, to first insert a part of the handle, such as an axle part, into the handle sleeve, and then to press the reducing ring into the rest of the handle sleeve, whereby this part of the handle, such as the Axle part, is held captive in the grip sleeve. In addition, the thread size of the internal thread of the grip sleeve can be easily adapted to the external screw thread.

In a further advantageous development it is provided that the handle has an axle part and a handle part, an axial axle part channel being formed in the axle part through which the core of the Bowden cable is guided, and that the axle part is attached to the handle part. The two-part handle is particularly easy to manufacture and assemble. In particular, the axle part can first be guided through the handle piece sleeve and then provided with the handle part so that the handle piece and handle piece sleeve are then captively connected. For this purpose, the axle part typically has a circumferential radial projection (collar) or several radial projections at the front end, with which the axle part engages behind a shoulder on the handle sleeve.

In a preferred embodiment of this development, the handle has on his rear end on a removable cover which covers a cavity in which the rear coupling body is arranged. The rear coupling body is easily accessible via the cover, in particular in order to attach or place it (during assembly) on the core, or to remove it (for repair or maintenance). In addition, the cover prevents the risk of injury to the core (which is often sharp-edged at the rear end) or to the rear coupling body through the cover, and makes unauthorized manipulation of the rear coupling body more difficult.

It is preferably provided that the axle part channel opens into the cavity and that the coupling stop for the rear coupling body of the Bowden cable is formed at a rear end of the axle part. This design is particularly simple and robust, since the axle part can easily be made of metal, such as steel.

Alternatively, it can also be provided that the handle part forms a bottom for the cavity, a bottom hole being provided in the bottom through which the core of the Bowden cable is guided, and that the coupling stop for the rear coupling body of the Bowden cable is through the bottom of the cavity is trained. This design avoids a gap that is accessible from the cavity between the axle part and the handle part, as a result of which the handle piece arrangement is less susceptible to soiling.

An embodiment of the above development is also advantageous in which the handle part is designed with a handle part internal thread into which the axle part is screwed with an axle part external thread. As a result, the assembly of the axle part on the handle part is particularly simple.

It is preferably provided that the handle part has an insert which forms the internal thread of the handle part, the insert being encapsulated by the rest of the handle part. The insert can be made of metal, for example steel, just like the axle part, so that a particularly robust attachment of the axle part to the handle part is possible, even if the handle part is otherwise made of plastic.

An embodiment of the above development is also advantageous in which the rear section of the axle part is pressed into a handle part receptacle of the handle part. This design keeps the number of parts in production low.

In an advantageous development, the rear coupling body is reversibly attached to the core of the Bowden cable, in particular clamped to the core by means of a grub screw. This makes assembly and repair easier, especially on the Bowden cable.

A further development is also preferred in which the handle sleeve and / or the handle form one or more shoulders with which the handle can be placed on the handle sleeve in the pulled-out position in order to automatically remain in the pulled-out position, in particular wherein the handle is rotatably mounted with respect to the handle sleeve in order to change between a mutual stop of the handle and handle sleeve in the extended position and in the retracted position. This increases the ease of use of the locking bolt system or the handle arrangement in a simple manner. The user does not need to keep the handle pulled in order to maintain the retracted position of the locking pin.

Further advantages of the invention emerge from the description and the drawing. The features mentioned above and below can also be used according to the invention individually or collectively in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for describing the invention.

The 1 in a schematic longitudinal section and the 2 show in a schematic perspective view a first embodiment of a locking bolt system according to the invention 1 in a front section 1a , in an extended position of the locking pin 2 . The front section 1a includes a locking pin assembly 3 and a first (front) part of an actuation arrangement 4th therefor.

The locking pin arrangement 3 includes the locking pin 2 as well as a bolt sleeve 5 , in which the locking pin 2 along a bolt axis BA is axially movable. The locking pin 2 is made by means of a spring 6th , here a compression spring designed as a helical spring, biased into an extended position in which the locking bolt 2 with a front bolt tip 7th from the bolt sleeve 5 protrudes. The inside of the stud sleeve 5 arranged spring 6th is supported by the shoulders on the locking pin 2 and on the bolt sleeve 5 are formed from and sits on a central part of the locking pin 2 on.

The locking pin 2 forms at its rear end (In 1 right) a male bolt thread 8th from which an adapter sleeve 9 with an adapter sleeve internal thread 10 is screwed on.

Furthermore, the bolt sleeve 5 a male bolt sleeve thread 11 on, which is here over the entire axial length of the outside of the bolt sleeve 5 extends. In the area of a rear end of the bolt sleeve 5 is on the external thread of the stud sleeve 11 a sleeve 12th with a female union thread 13th is screwed on. In the embodiment shown, there is also a nut 14th , here a hexagon nut, on the male bolt sleeve thread 11 unscrewed.

By means of the external thread of the bolt sleeve 11 and the mother 14th can the bolt sleeve 5 screwed into a first component (such as a stationary structure, not shown) and braced on this, with the front bolt tip 7th can be engaged in a second component (not shown) so as to counteract this second component against transverse forces or a displacement of the second component relative to the first component transversely to the bolt axis BA to secure.

The locking bolt can be used to temporarily release the second component 2 by means of the actuation arrangement 4th against the force of the spring 6th into the stud sleeve 5 be retracted (see also 3 below). The actuation arrangement 4th includes in the front part 1a the locking bolt system 1 in the embodiment shown, the adapter sleeve 9 who have favourited the union sleeve 12th and a front part of a Bowden cable 15th with a soul 16 and a Bowden cable cover 17th .

The adapter sleeve 9 forms an interior 18th from which at its rear end (in 1 right) through an adapter sleeve base 19th is limited. In the adapter sleeve base 19th is an adapter sleeve hole 20th trained through which the soul 16 of the Bowden cable 15th is led. At the front end of the soul 16 is a front coupling body 21 , here a coupling ball 21a , irreversibly attached, for example welded on. The coupling ball 21a engages behind the adapter sleeve base 19th . The coupling ball 21a has a diameter that is slightly smaller than the (internal) diameter of the adapter sleeve internal thread 10 so that the soul 16 from the front (in 1 left) through an insertion opening 30th into the adapter sleeve 9 can be threaded, and the coupling ball 21a through the insertion opening 30th up to the adapter sleeve base 19th can move closer. The adapter sleeve 9 is via a clamping ring 22nd with the locking pin 2 braced, the clamping ring 22nd in an annular groove of the locking pin 2 is arranged. In other designs, the clamping ring 22nd also omitted.

The adapter sleeve 9 becomes of the union sleeve 12th encroached upon; in other words is the adapter sleeve 9 in an interior 23 the sleeve 12th arranged and is thereby completely covered from the environment. The interior 23 is designed to be large enough to allow the locking pin to move axially 2 including adapter sleeve 9 on or within the sleeve 12th backwards (in 1 to the right) when the locking pin arrangement is actuated 3 , i.e. when the locking pin is retracted 2 into the stud sleeve 5 to allow. In the embodiment shown, it is on the union sleeve 12th a key surface on the outside in the area of the rear end 29 , here a hexagon.

The union sleeve 12th directly forms a first abutment here 24 for a front stop end 25th the Bowden cable cover 17th out. This is in the sleeve 12th a recess in the area of its rear end 27 formed, the front stop end 25th on a recess ground 26th the recess 27 is present. A recess hole 28 leads from the recess 27 to the interior 23 the sleeve 12th , being the soul 16 of the Bowden cable 15th through this recess bore 28 is passed through.

Is now through a second (rear) part of the actuator assembly 4th (please refer 4-6 below) the soul 16 opposite the Bowden cable cover 17th pulled back (in 1 the soul 16 pulled to the right), the essentially pressure-resistant Bowden cable casing is supported 17th on the union sleeve 12th off, and the soul 16 pulls by means of the front coupling body 21 the adapter sleeve 9 in the interior 23 the sleeve 12th backwards (in 1 to the right), and with it the locking pin 2 backwards (in 1 to the right) into the stud sleeve 5 into it.

The 3 shows a corresponding, retracted state of the locking pin 2 into the stud sleeve 5 . Thereby the spring 6th compressed; the retraction of the locking pin 2 thus takes place against the force (the counter pressure) of the spring 6th . So long with the Bowden cable 15th the tensile force on the locking pin 2 is maintained, the locking pin remains 2 in the retracted state. If the tensile force is no longer maintained, the locking pin moves 2 under the force of the spring 6th again out of the bolt sleeve 5 from, to the in 1 shown state, whereby also the soul 16 opposite the Bowden cable cover 17th back to the front (in 3 to the left).

The 4th in a schematic longitudinal section and the 5 in a schematic perspective view is a rear portion 1b the locking bolt system 1 the first embodiment shown. The rear section 1b forms the second (rear) part of the actuator assembly 4th off, and here includes a rear part of the Bowden cable 15th , still a grip sleeve 40 and a handle 41 .

In the embodiment shown is on the handle sleeve 40 indirectly a second abutment 42 for a rear stop end 44 the Bowden cable cover 17th in an abutment screw 43 educated. The abutment screw 43 is in the area of its rear end (in 4th right) with an external screw thread 45 formed and in the handle sleeve 40 screwed in.

The abutment screw 43 forms at its front end (in 4th left) a mug 46 in which the rear stop end 44 the Bowden cable cover 17th is inserted, the rear stop end 44 axially on a cup base 47 is present. The cup 46 has a key surface here on the outside 66 on. The abutment screw 43 is also with a screw channel 48 trained in the cup 46 flows through, and through which the soul 16 of the Bowden cable 15th is passed through.

To adjust the bowden cable 15th , so to tension the soul 16 opposite the Bowden cable cover 17th , can be the screw-in depth of the abutment screw 43 in the grip sleeve 40 adjusted or set. A desired adjustment position of the abutment screw 43 can by means of a lock nut 67 secured.

In the embodiment shown, the abutment is screw 43 into a grip sleeve internal thread 49 screwed in, which is in a reducing ring 50 is trained. The reducing ring 50 is in the rest of the handle sleeve 40 pressed in. The grip sleeve 40 here has a handle piece external thread in a front area 51 with which the grip sleeve 40 can be screwed into a (mostly stationary) structure (not shown). Furthermore, the handle sleeve is in a rear area here 40 a wrench flat 52 on the outside of the handle sleeve 40 educated.

In the grip sleeve 40 is the handle 41 along the handle axis GA axially movable. In the embodiment shown, the handle is 41 with an axle part 53 and a handle part 54 formed, the axle part 53 with its front end in the handle sleeve 40 protrudes and with a circumferential projection 55 on the inside of the handle sleeve 40 and a shoulder protruding radially inward 56 the grip sleeve 40 engages behind. This is the handle 41 captive in the grip sleeve 40 held. The axle part 53 is made of steel.

In the axle part 53 is an axial recess 57 formed whose diameter is large enough so that (depending on the adjustment position of the abutment screw 43 ) the abutment screw 43 in this axial recess 57 can protrude.

In the embodiment shown, the axle part has 53 at its rear end via a male axle thread 58 into a handle part internal thread 59 is screwed in. This is the axle part 53 firmly with the handle part 54 connected. The handle part internal thread 59 is here in an insert 60 of the handle part 54 formed, and the rest of the handle part 54 was made by overmolding the insert 60 Made of plastic by injection molding. The depositor 60 is made of steel. The Handle part 54 forms a cavity 61 made by a removable cover 62 is locked.

In the axle part 53 is an axle part channel running in the axial direction 63 trained by the soul 16 of the Bowden cable 15th leads. The axle part channel 63 opens here in the axial recess 57 and directly in the cavity 61 .

On the soul 16 is a rear coupling body 64 reversibly attached; in the embodiment shown is the rear coupling body 64 with a grub screw on the soul 16 uptight. The axle part 53 here forms a coupling stop at its rear end 65 from where the rear coupling body 64 is present. The rear coupling body 64 and the section of the soul behind it 16 protrude into the cavity 61 .

For mounting the rear section 1b of the locking bolt system, the procedure is typically as follows: First, the axle part 53 from the front into the handle sleeve 40 plugged in. Then the axle part 53 in the handle part 54 screwed in, and the reducing ring 50 into the grip sleeve 40 be pressed in. Then the soul can 16 through the abutment screw 43 and the axle part 53 be threaded. Then the abutment screw 43 into the grip sleeve 40 screwed in, preferably as far as possible, around the subsequent fastening of the rear coupling section 64 on the soul 16 to facilitate. Finally the abutment screw 43 unscrewed a little again until the desired tension of the Bowden cable 15th is reached, and the lock nut 67 on the abutment screw 43 is tightened.

In the in 4th position of the handle shown 41 this is up to the end of the handle sleeve 40 and handle 41 formed stop retracted; the spring of the locking pin arrangement (see 1 , reference number there 6th ) a preload in this position. At the same time, the locking pin is fully extended (see 1 ).

The handle can now be used to retract the locking pin 41 relative to the grip sleeve 40 axially backwards (in 4th to the right). The rear end of the stop 44 the essentially pressure-resistant Bowden cable cover 17th is based on the second abutment 42 or the cup base 47 the abutment screw 43 from which axially fixed to the handle sleeve 40 is attached. The Bowden cable casing therefore moves accordingly 17th relative to the grip sleeve 40 Not. On the other hand, the soul will 16 via the rear coupling body 64 through the coupling stop 65 of the handle 41 relative to the grip sleeve 40 backwards (in 4th to the right). The soul becomes accordingly 16 also relative to the Bowden cable cover 17th that are indirectly attached to the handle sleeve 40 supported, pulled to the right.

The 6th shows an extended position of the handle 41 to the grip sleeve 40 . This pulled out position of the handle 41 corresponds to the in 3 shown, retracted position of the locking bolt in the bolt sleeve.

The bowden cable 15th can be selected with a suitable length as required, to the location of the installation of the bolt sleeve or the locking bolt arrangement on the one hand and the location of the installation of the handle sleeve 40 and the handle 41 on the other hand to connect. During its assembly, the Bowden cable 15th bent as required and, in particular, laid with one or more bends. Note that after installing the Bowden cable 15th and its bracing / setting via the adjustment position of the abutment screw 43 the bend on the Bowden cable 15th should no longer be changed.

The 7th shows in a schematic longitudinal section a second embodiment of a locking bolt system according to the invention 1 in its rear part 1b ; only the essential differences from the embodiment of 1-6 explained.

In the embodiment of 7th is the handle part 54 with a handle part holder 70 in the form of a front (in 7th from the left) accessible, central axial recess. In the handle part holder 70 is a central rear section 71 of the axle part 53 pressed in immediately. In this case, no insert is required, and the handle part 41 is easier to manufacture.

The handle part made of plastic 54 continues to form a floor here 72 for the cavity 61 out. The floor 72 has a bottom hole 73 on through which the soul 16 is performed on which the rear coupling body 64 is attached. The rear coupling body 64 lies on the ground 72 on so the bottom 72 of the handle part 54 the coupling stop 65 for the rear coupling body 64 trains.

Furthermore, the handle 41 on the handle part 54 at its front (in 7th left) end of paragraphs 80 on, which can also be referred to as axial projections. Conversely, the grip sleeve has 40 at her rear (in 7th right) end via complementary recesses 83 so that the handle 41 and the handle sleeve 40 are axially plugged into one another. The handle 41 lies here on a radially inner one Guide process 85 the grip sleeve 40 as an axial stop; at the same time the guide extension carries 85 for mutual radial alignment of the handle 41 and grip sleeve 40 at.

The design of the paragraphs 80 and returns 83 is in 8th even better visible in a schematic perspective view; 8th shows how 7th the retracted position of the handle 40 .
