Description

The invention relates to a padlock with a lock body and Shackle that can be coupled to the lock body at its shackle ends and coupled state is lockable.

With such locks there is the problem of being hit by the lock body in the locked state, the locking mechanism can be deformed or moved that the bracket even in the locked state can be pulled out of the lock body. activities to reinforce the lock body could be a better one Protection of the locking mechanism would result, however, in disadvantageous Way increase the weight of the lock.

The object of the invention is to provide a padlock of the type mentioned to create the most burglar-proof possible with the lowest possible weight is.

This object is achieved in that in Lock body two physically separate power cells for receiving the temple ends are arranged and each load cell one between a locking state and a release state adjustable locking arrangement is assigned for a temple end that has a Locking unit can be actuated, at least one locking arrangement has a locking element which in the locked state with its supported on the load cell from the inserted side facing away from the bracket is.

The inventive support of the locking element on the power cell prevents the locking element from disengaging in the locked state can be moved with the temple end. The support of the locking element on the power cell can either directly or indirectly via an additional separate component. Deformation of the bolt actuations by striking the lock body affect the locking condition not because such deformations have no influence on the support of the locking element on the power cell. Applied from the outside Break-out forces trying to lock the locking element to move out of its locked position taken up by the power cell according to the invention and in this way disabled.

It is particularly preferred if at least in the case of a force cell the inserted temple end with its facing away from the locking element Side and the locking element supported on the same component of the power cell is. This creates a particularly stable power cell.

In this case, at least one power cell can be used in particular as a drilling protection and / or impact protection trained walls through which a Protection area for at least the temple end and the locking element at least is partially limited. Here, the power cell is not only used for absorption of forces acting on the temple end and the locking element, but also increases the resistance to other outside Influences such as Try the locking engagement between the temple ends and unlock the locking element by drilling.

In a particularly preferred practical embodiment of the invention has at least one power cell with the open side of the other Load cell facing U-profile. The U-profile can be arranged that the temple end is inserted laterally between the U-legs and in inserted state is therefore perpendicular to the U-legs. It is preferred if the bracket end with one facing away from the locking element Side on the U-web connecting the U-legs and the locking element is supported on at least one U-leg. The temple end and the locking element are thereby on three sides of profile walls surrounded and protected from external influences. In particular, this ensures Design for advantageous protection of the temple end on the front side of the lock body through the U-web of the U-profile.

The locking arrangement can be made in several parts and in addition to the locking element, an actuating element that can be actuated via the locking unit have, via which the locking element indirectly on the load cell is supported. Alternatively, it is also possible to use a one-piece locking arrangement in the form of a directly supported on the power cell To provide locking element, both with the inserted end of the bracket cooperates and can also be actuated via the clamping unit.

In a preferred embodiment of a multi-part locking arrangement is the actuator as an actuating arm and a support arm having swivel lever formed. Via the operating arm can the swivel lever by means of the locking unit between a locking position, in which the locking element on the support arm on the power cell supported and thus by the support arm in a locking position is secured, and a release position can be pivoted in which it is possible to remove the locking element from its locking position out move.

A pivotable mounting of the pivot lever on the power cell can For example, take place in that the pivot lever between opposite Walls of the load cell extends to storage areas forming breakthroughs in the walls is supported.

It is particularly preferred if the locking arrangement is self-locking is trained. This can e.g. due to a lost motion and / or a play of the control element. By self-locking can achieved that in typical attempts to break open, e.g. beats on the lock body, the securing effect of the control element does not deteriorate or canceled, but rather reinforced.

A preferred way of realizing such a self-locking the locking arrangement is to close the actuator store that it has a maximum adjustable locking position with the clamping unit is further movable, with each additional Position the locking element supported on the actuator on the power cell or is secured. In this way, the inertia of the actuator be exploited, the one when striking the lock body Relative movement between the moving force cell and the control element.

It is preferred if the actuating element by such a relative movement can be brought into engagement with the locking element and in particular can be clamped or wedged between the locking element and the power cell is.

Because of the self-locking effect according to the invention by striking the lock body does exactly the opposite of what is the purpose of such attempts to break open.

In a further preferred embodiment of the invention that is Locking element in the release state by pulling out the temple end can be moved out of the power cell from a locking position. there it is preferred if the locking element is arranged by an element arranged in the force cell or spring element protruding into the force cell into the locking position is biased. The restoring force of the spring element is preferably set so that the inserted bracket falls out is held on the lock body.

Further preferred embodiments of the invention are also shown in FIGS Subclaims, the description and the drawing.

Fig. 1 shows the padlock according to the invention, the lock body 10 and a bracket 12, in a locked state, in which the bracket 12 with its bracket ends 14 explained in more detail below Load cells 16 of the lock body 10 are inserted into one tubular housing 28 spatially separated from each other in the area a pipe end are arranged.

To lock each bracket end 14, one is arranged in the load cell 16 Locking arrangement provided that a locking element 18 in Form of a roller and an adjusting element in the form of a pivot lever 20 includes. In the locked state, the locking element 18 is in a locking position in which it is adapted to its shape Bolt receptacle 15 of the bracket end 14 engages and by a support arm 34 of the pivot lever 20 is supported on the load cell 16. To this The locking element 18 is secured in the locking position. On Actuating arm 33 of the pivot lever 20, one with the support arm 34 Includes angles of more than 90 ° and protrudes from the load cell 16, is coupled to one end portion of a linkage 26 which at its opposite end area with an actuator 50 communicates. Form the linkage 26 and the actuator 50 an actuation arrangement via which the two pivot levers 20 by means of a locking cylinder 23, only schematically indicated Locking unit 22 between the locking position shown and a release position can be pivoted.

The actuator 50 is connected to the lock cylinder 23 in a rotationally fixed manner, so that by turning the lock cylinder 23 by means of an inserted Key (not shown) the linkage 26 via actuating pins 52 of the actuator 50 can be adjusted along its longitudinal axis can.

The identical load cells 16 each comprise a U-shaped profile 17 made of hardened metal with the U-legs, parallel to each other extending profile walls 36. The U-profiles 17 are with their open Sides facing each other and arranged so that the bracket 12 with his Temple ends 14 can be inserted between the profile walls 36.

Relative to insertion openings formed in the lock body 10 for the Brackets 12, the U-profiles 17 are each positioned in the lock body 10, that the bracket end 14 with its from the locking arrangement 18, 20 opposite side supported on the profile wall forming the U-web 35 is.

Openings 37 are formed in the profile walls 36, on the boundary edges thereof the locking element 18 and the actuating element 20, which are extend between the profile walls 36 are supported.

The openings 37 each have a receiving area 37a for this purpose the roller 18 on, a movement perpendicular to the inserted temple end 14 and thus in the longitudinal direction of the profile walls 36. On Bearing areas 37b of the openings 37 is the pivot lever 20 pivoted and supported at the same time in such a way that a translational Movement of the pivot lever 20 perpendicular to the inserted Temple end 14 is not possible.

Due to the shape of the openings 37, the swivel range for the Swing lever 20 limited by the fact that the boundary edges of the Openings 37 stop surfaces 37c for the support arm 34 of the pivot lever 20 form.

In the region of their free ends, the profile walls 36 have cutouts 36a provided, in the projections 25 of a merely shown schematically Intervene receiving housing 24 for the clamping unit 22. On in this way, the U-profiles 17 are pull-proof on the receiving housing 24 attached and coupled to each other via the receiving housing 24. The U-profiles 17 can be pushed onto the projections 25 with the Receiving housing 24 are locked.

Fig. 2 shows in Fig. 1 not shown additional components in the area the load cells 16 are arranged. On the one hand, it is about a spring arrangement made of plastic, which is perpendicular to the profile walls 36 extending plate-shaped carrier 32 includes the outside of the U-profile 17 is arranged and on the side edges of the U-profile 17th is applied. The carrier 32 is in one piece with spring tongues projecting vertically 30, 31 connected between the profile walls 36 in protrude into the load cell 16.

A spring tongue which grips the roller 18 in regions with its free end 30 is used to keep the roller 18 in its locked position to hold when the pivot lever 20 is pivoted into the release position in which the roller 18 is not secured by the support arm 34 and is therefore not supported on the U-profile 17 via the pivot lever 20.

In this release state, the locking element 18 can be pulled out the bracket end 14 from the load cell 16 against the restoring force of the Spring tongue 30 perpendicular to the inserted bracket end 14 from its locked position be moved out. The spring tongue 30 is on the bracket 12 matched that their restoring force is sufficiently large to prevent the bracket 12 from falling out solely due to its own weight to prevent the inserted bracket 12 from falling out when released on the lock body 10 by the in its locking position biased locking elements 18 is held.

The other spring tongue 31 attached to the carrier 32 serves as a holding member for the pivot lever 20, the pivot lever 20 in the storage areas 37b of the profile walls 36 holds. As a result, only swivel movements of the actuating element 20 possible, but translatory movements are prevented by the holding member 31.

Fig. 2 also shows a cushion, buffer made of plastic or damping element 54, which on the inside facing the bracket 12 I of the lock body 10 between its housing 28 and the U-profile 17 is arranged. The damping element 54 projects with a nose 55 up to the locking element 18 into the load cell 16. The one on both power cells 16 arranged damping elements 54 are an additional protection against burglary, cushioned the blows on the housing 28 of the lock body 10. This damping is the subject of the same day as this one German patent application filed by the applicant, the disclosure content of which is hereby incorporated by reference into the present application is included.

The on the outside of the lock body 10 between the housing 28 and the U-profile 17 arranged carrier 32 also ensures a such impact protection.

The power cells 16 according to the invention can, on the one hand, be large external forces are absorbed in a closed system. To the others allow the force cells 16 to have a geometrical arrangement of the Locking arrangements or the locking elements such that outer Forces are distributed more evenly and force or voltage peaks avoided become. A distribution of external forces takes place both spatially, namely by increasing the range of spread, as well as temporally, namely by reducing mass accelerations. The upholstery mentioned above also works in this sense, Buffering or damping 54.

3 shows in particular that the support arm 34 of the actuating element 20 is fork-shaped, so that the spring member 30 and Protruding member 31 protrude between the fork arms of the support arm 34 can.

3 are formed in the end regions of the linkage 26 Recesses 27 are shown, in each of which the actuating arm 33 of the pivot lever 20 engages with its free end. The operating arms 33 are arranged with play in the recesses 27. This Game enables a self-locking function of the locking arrangement 18, 20, which are explained in more detail below in connection with FIG. 8 becomes.

There are guide holes in regions of the linkage 26 lying one above the other 53 formed with the actuating pins 52 of the locking cylinder 23 of the clamping unit 22 rotatable actuator 50 cooperate. Each of the two arms of each guide hole 53 serves an arm for receiving the rod 26 in question displacing Actuating pin 52 while the other arm makes an undisturbed movement of the actuating pin used to move the other linkage 26 52 allows. In the illustrated embodiment, the in Fig. 3 right actuating pin 52 for moving the lower linkage 26, while the upper linkage 26 is moved.

4 shows in particular that on each of the two load cells 16 little or no play between the U-web 35 of the U-profile 17 and the temple end 14, between the temple end 14 and the Roller 18, between the roller 18 and the fork-shaped support arm 34 of the Pivot lever 20 and between the pivot lever 20 and the profile walls 36 is present.

In the locking state shown, the bracket end 14 is thus directly and the locking element 18 indirectly via the actuating element 20 to each other opposite sides of the same component of the load cell 16, namely the U-profile 17, supported. Movements of the locking element 18 are supported and secured in this by the actuator 20 Locking position not possible. This locked state can also attempts to break open, such as blows to the lock body 10 do not harm anything, as this may result in Deformations of the linkage 26 have nothing to do with the immobility of the locking elements 18 change.

5 shows in particular that through the recess 27 of the linkage 26 protruding actuating arm 33 of the pivoting lever 20.

The storage, in particular, is shown in the perspective view in FIG. 6 of the pivot lever 20 in the bearing areas 37b or in the profile walls 36 trained breakthroughs 37 emerge. For this are the fork arms of the fork-shaped support arm 34 on its from the locking element 18th opposite end rounded so that they form bearing surfaces 34b with which the pivot lever 20 in the correspondingly shaped storage areas 37b of the profile walls 36 or the openings 37 is seated.

In Fig. 7 is particularly the corresponding to the outer contour of the roller-shaped Bolt element 18 shaped bolt receptacle 15 of the temple end 14 recognizable.

The side view of Fig. 8 shows a locked state in which the pivot lever 20 in a maximum over the clamping unit 22 adjustable locking position is located, d. H. by means of a Lock cylinder 23 inserted key, the pivot lever 20th no longer be turned counterclockwise (refer to Fig. 8), although between the support arm 34 and the corresponding stop surface 37c of the openings 37 there is a small space which a further pivoting movement of the pivot lever 20 against the Would allow clockwise.

At such a further movement over the maximum adjustable locking position addition, the pivot lever 20 is not, however, by the the linkage 26 comprehensive actuator assembly prevented because of Actuating arm 33 of the pivot lever 20 with play in the recess 27 of the linkage 26 is arranged (cf. in particular Fig. 3). It is therefore a Lost motion or a game of the in the maximum adjustable locking position located pivot lever 20 is present, thereby a self-locking function the locking arrangement 18, 20 is realized.

The inertia of the pivot lever 20 has the consequence that in the event of impacts the inside I of the lock body 10 of the pivot lever 20 further relative to the U-profile 17 is pivoted counterclockwise until it at the Abutment surface 37c.

With this further pivoting movement of the pivot lever 20 is a stroke of part of the support surface facing the locking element 18 34a of the pivot lever 20 connected in the direction of the bracket end 14, whereby the locking element 18 is pressed against the bracket end 14. With a small game e.g. between the U-web 35 of the U-profile 17th and the bracket end 14, this stroke can be accommodated.

The size of the stroke is particularly between the relative arrangement Locking element 18 and pivoting lever 20 and of the course of the support surface 34a dependent.

In the embodiment shown, it closes perpendicular to the sides of the support arm 34 extending support surface 34a in the maximum adjustable 8 with a the pivot axis S of the Swivel lever 20 and the central axis R of the locking element 18 connecting Line up an angle other than 90 °.

Blows on the inside I of the lock body 10 thus have a Self-locking of the locking arrangement 18, 20 results in a Wedge of the support arm 34 of the pivot lever 20 between the Latch element 18 and the U-profile 17 leads.

The support arm 34 of the pivot lever 20 can be adjusted to the maximum Locking position also further away from the stop surface 37c be as shown in Fig. 8. Furthermore, the support surface 34a needs this Locking element 18 is not in the maximum adjustable locking position to touch. The relative arrangement between locking element 18 and Swing lever 20 is in any case such that not only in the maximum adjustable locking position, but also in everyone above it outward position of the pivot lever 20, the locking element 18th by the support arm 34 of the pivot lever 20 in its locking position is secured.

9 and 10 show a further embodiment of the invention, at which the locking element 118 is bent into a U-shape and between the Profile walls 36 of the U-profile 17 extends. In its locking position shown the locking element 118 is only indicated by FIG. 9 Spring member 130 biased between the U-legs 118a of the locking element 118 is arranged.

An actuating element 120 is vertical over the locking unit of the lock displaceable to the U-legs 118a of the locking element 118, whereby it is guided in the openings 37 of the profile walls 36 U-profile 17.

The U-legs 118a of the locking element 18 are each at their free Ends with laterally arranged extensions forming engagement sections 119a Mistake.

9 and 10 is a release state of the locking arrangement 118, 120 shown, in which the locking element 118 with its extensions 119a can be moved past the actuating element 120 or through cutouts 120a of the actuating element 120 is movable therethrough.

In the released state, the locking element 118 can thus be pulled out the bracket end 14 from the load cell 16 against the restoring force of Spring member 130 are moved out of its locked position.

By moving the control element 120 over the clamping unit and a suitable, connected between the clamping unit and the actuator 120 The actuating arrangement is the locking element 118 in its locking position supported on the control element 120 on the U-profile 17 and thus secured in its locked position.

11 and 12 show a further embodiment of the invention, in which the locking arrangement is made in one piece and a locking element 218 includes that on a corresponding to the bolt receptacle of the Temple end 14 curved side cooperates with the temple end 14 and on its side facing away from the inserted temple end 14 Actuating arm 233 and a fork-shaped support arm 234. The operating arm located between the fork arms of the support arm 234 233 is angled relative to the support arm 234 in such a way that a Locking unit of the lock perpendicular to the inserted temple end 14 adjustable actuator 226 with a hook-like actuator section 226a the locking element 218 via the actuating arm 233 from the locking position shown in a release position in Can pivot clockwise (based on Fig. 11).

While in the locked state, the locking element 218 over its Support arm 234 on openings 37 in the profile walls 36 of the U-profile 17th limiting support portions 217a is supported, the locking element 218 in the release state that can be set by pivoting its locking position out past the support portions 217a and with its support arm 234 in one adjacent to the support portions 217a Area of the openings 37 are moved into it.

By a securing portion 226b of the actuator 226 is in Locking state of the locking element 218 via its support arm 234 in locked position.

The pivoting movement of the locking element 218 from the locking position in the release position can against the restoring force of a spring element respectively. Furthermore, a spring element can be provided which biases the locking element 218 into engagement with the bracket end 14 and against its restoring force, the locking element 218 from the Locking position in the unlocking position by pulling out the bracket end 14 can be moved from the power cell 16.

One to the. Securing section 226b adjacent slope 226c of the Actuator 226 ensures that the locking element 218 is secure via its support arm 234 from the unlocked position back into the Locked position is moved when the actuator 226 over the clamping unit is adjusted in the direction of the temple end 14.
