Definitions

  • the invention relates to a lock, according to the preamble of claim 1.
  • Such a lock is for example from the US patent 5 189 893 known.
  • the well-known castle are strong Tensile forces on the locking pin, which for example unauthorized attempts to break open on the locking pin be, by support on the actuator and on a blocking device influencing the control element added.
  • the present invention is based on the object Train the lock with the lock body and locking pin so that with strong pull-out forces on the locking pin adjusting reaction forces from the actuator and one blocking device assigned to the control element if possible be kept away.
  • the lock construction according to the invention brings the big one Advantage that the sensitive parts, actuator and Blocking device, largely when trying to break open are relieved. This means that on the one hand attempts to break open are difficult and on the other hand unsuccessful attempts to break open not to deformation on the actuator and / or the blocking device can lead. In order to there is a chance that a lock construction type according to the invention also attempts to break open with the greatest power survived undamaged.
  • the construction principle according to the invention can be done in the way be realized that the abutment on a preferably plate-shaped abutment element is formed, which keeps the closing mandrel in its closing mandrel closing position at least partially embraced and opposed to it one essentially transverse to the closing mandrel extension direction directional shear force, which acts upon the action of a Pull-out force on the locking pin as a result of the pinching of the locking element between the closing surface and the abutment results.
  • This training measure ensures that the Lock body itself from transverse forces as a result of locking pin pull-out forces is largely relieved. On the lock body then essentially occur only to the closing mandrel extension direction parallel reaction forces that are proportional easily and without much construction and material can be included.
  • the abutment element can be on the inside of a housing wall of the lock body so that when dimensioning the Essentially only with regard to attempts at pulling out still on the dimensioning of the foremost housing wall in the pull-out direction of the lock body must be respected. Is preferred to Purpose of the introduction of transverse force into the locking mandrel the abutment element with one completely enclosing the locking pin Breakthrough accomplished.
  • the abutment can from the edges of a mandrel passage opening be formed in the abutment element. This facilitates the production of the abutment by for example the closing mandrel passage opening and its Extension made in a single punching process can be.
  • the principle according to the invention is particularly applicable if the locking element by the actuator under spring force is biased into the locking position and if the closing mandrel under cam-like interaction with the Bolt element retractable from the locking pin closing position is, the locking element in the direction of the Release position evades.
  • the design of the closing surface naturally depends on the Design of the closing element. If you use one Rolling elements and in particular a ball as a closing element, it is also recommended to make production easier, the closing surface as a partial cylinder surface or form a spherical cap surface, with the design the closing surface in turn towards it make sure that the closing mandrel is pulled out when it is released Blocking device counteracts a resistance, on the one hand an unintentional falling out of the locking pin prevented from the locking pin holder, on the other hand also the normal handling of the lock is not excessive difficult.
  • This reaction force is in the construction of the Lock easily calculable.
  • An elastic deflection of the locking element is important because one after a large pull-out force on the locking pin the castle wants to remain usable.
  • a guide track that meets the requirement, the locking element until entry into the locking position in essentially without one existing in the direction of the mandrel extension Leading play can be done through a guide channel realize within the lock body, in particular a guide channel which can be expanded elastically in this way is that when a predetermined one is exceeded Pulling force on the locking pin an elastic dodge the locking element from its guideway in the closing mandrel extension direction allowed.
  • a guide channel leaves reach themselves in particular if the guide channel of a plastic part is formed.
  • the elastic Evasion by slitting the guide channel or by a tapered design of the guide channel cross section favored.
  • the control element can, as already indicated, by a Blocking device can be blocked in its locked position be, the blocking device preferably based a commercially available locking cylinder is built.
  • the blocking device with a rotatable cam be executed, which in a blocking position the blocking device from evading the actuating element blocked in its retracted position and in a non-blocking position, a displacement of the actuating element from its locked position to its retracted position permitted against spring force.
  • the cam can be on the lock cylinder core of the lock cylinder for common Rotation with this be appropriate.
  • the lock is provided that the lock cylinder in a holding part is at least partially received which the guideway for the locking element and / or that Control element is formed.
  • the lock body can have a tubular housing be executed and within this tubular housing have a holding part in which the guideway for the Locking element and / or the actuating element is formed. Because when applying the principle of the invention no essential Reaction forces from strong pull-out forces on the actuator and the blocking device act, it is sufficient the tubular housing made of high-strength material, e.g. Steel sheet. On the other hand, it is harmless if the holding part with the guide track for the locking element and / or the control element and possibly with a Holding chamber for the locking pin and with a bearing for the blocking device made of plastic, for example in casting or Injection molding process or made of die-cast zinc is because the holding part only has low reaction forces subject to. It is advantageous if the receiving chamber for the locking pin is also formed in the holding part, because then the number of parts for assembling the lock is necessary is reduced. The guideway then opens into the receiving chamber.
  • the locking element should be in when the locking pin is retracted be held in a position in which it is reintroduced of the closing mandrel without special preparation measures allowed. It is therefore provided that the locking element in its locking position against transfer from its The guideway is then also secured in the locking pin holder is when the striker comes out of the striker holder withdrawn. This backup can be done easily achieve that at an end close to the locking pin holder the guideway is provided with a narrowing of the guideway. There may also be slings to achieve this security be used.
  • the principle of the invention is basically known in all Locks applicable where one or more locking pins inserted in a locking pin holder and should be locked there. It is particularly interesting Application of the principle of the invention with a padlock a lock shackle on both ends of its shackle legs
  • One locking pin each for insertion in one locking pin holder has a lock body.
  • the Lock body as with padlocks for securing two-wheelers usual, with respect to a plane of symmetry of the lock be designed symmetrically, with a blocking device in a middle area between the two mandrel holders arranged and the two locking pin receptacles can be assigned together.
  • the holding parts can be made of plastic and need since they have no essential powers to absorb to be executed with thick walls. Rather, it is sufficient that Plastic distribution in the individual holding parts choose that on the one hand the guideways for the locking element and the actuator, the recording for the Locking pin and the holder for the blocking device are provided and on the other hand system edges or Contact surfaces for the correct positioning of the holding parts in an outer housing of the lock body stand.
  • the lock body can be a tubular housing round or polygonal, especially rectangular, Have cross section, which is the distance between the the two locking pin adapters bridged in a central area the blocking device receives and over the The locking pin holder only survives as far as for education the locking pin receiving chambers is required.
  • the Holding parts can be inserted into the from one or both ends tubular housing can be inserted after going before on both holding parts, the corresponding set-up parts, namely locking element, actuator, biasing springs and possibly pre-assembled locking plates.
  • the blocking device becomes one or the other in advance other pre-assembled unit in the tubular housing inserted and sits after inserting the two pre-assembled Units between these in the correct Position. Then you only need the holding parts in secure their retracted position, for example by Locking pins inserted into aligned holes in the tubular Enclosed housing and the holding parts or be pushed in. The cost of materials and the weight of the Lock body remain relatively small without the security function is affected.
  • the optical Appearance is essentially only due to the shape of the Housing, in particular tubular housing, and by the Form of the bracket determined, i.e. by two parts that one a surface design that is favorable in appearance with little effort can lend.
  • the blocking device can be ergonomically cheaper House way.
  • the key entry slot can be about with a rectangular cross section of the housing tube on each Side surface of the housing tube are attached. From ergonomic and manufacturing aspects it is of course preferred to use the key entry slot in the Area of a remote from the top of the lock bracket Attach the housing surface.
  • the design of the housing parts made of easily deformable material, especially plastic, allows any chamber boundary surfaces on these holding parts for the formation of the lock cylinder to form the receiving chamber so that you can choose the lock cylinder is a great choice within the commercial Range of locking cylinders.
  • a lock bracket is designated 10.
  • the two shackle legs 12 of the lock shackle are each with a locking pin 14 executed.
  • the locking pins 14 are in a lock body, which is generally 16 is designated.
  • the lock body 16 comprises a tubular one Lock body housing 18, which - as can be seen from Figures 4 and 5 - Has a rectangular cross-section.
  • the tubular Lock body housing 18 is a holding part from both ends 20 inserted.
  • the two holding parts 20 and their in the following Furnishing parts to be described are together identical, so the description of a single one of these Holding parts are sufficient.
  • the holding part 20 is as a plastic injection molded body executed, the middle section - as in Figure 4 shown - an essentially cup-shaped Cross section.
  • In the middle section is one after Fühgrungsbahn 22 open at the top of part-circular cross-section molded.
  • This guideway 22 is one Locking ball 24 out.
  • the guide ball 24 is for Engagement in a closing surface 26 of the locking pin 14 is formed.
  • At the end of the locking ball away from the mandrel 24 is an actuator 28.
  • This actuator 28 has a guide plate 28a and an adjusting leg 28b on.
  • the adjusting leg 28b lies with its close to the closing mandrel End on the locking ball 24.
  • the guide plate 28a is on the holding part 20 in the upper region of the cup profile Slidable above the guideway 22 in the direction of arrow 30 guided.
  • a helical compression spring 32 which on Housing 34a of a locking cylinder, designated overall by 34 is supported.
  • the guideway 22 extends in the area of the locking ball 24 in its cross section over more than 180 ° of the locking ball 24, so that too when the locking ball is under normal operating conditions 24 in the closing surface 26 of the closing mandrel 14 engages the locking ball 24 in the direction of Double arrow 38 no essential game against the guideway 22 has.
  • the double arrow 38 represents the Mandrel insertion direction or mandrel extension direction of the locking pin 12 relative to the lock body 16.
  • the lock cylinder 34a has a lock cylinder core 34b executed and based on the principle of key chest controlled spring-loaded tumbler pin pairs. Of the Key 34c can be viewed from below through a slot 40 of the tubular housing 18 inserted into the lock cylinder so that the lock cylinder core 34b is rotated can.
  • a cam 44 attached, the shape of which in particular Figure 3 can be seen. Lie on this cam according to Figure 3 on the guide plates 28a in the area of radially projecting cams 44a. These cams are 44a dimensioned so that in the assignment according to Figure 2, the locking balls 24 engaged by the actuating elements 28 are held with the respective closing surfaces 26.
  • the locking pin 14 Since, as already stated, the locking balls 24 also in this position is still essentially free of play in the direction of the double arrow 38 through the respective guideway 22 are guided, the locking pin 14 has a normal load essentially no play in the pull-out direction according to FIG. 38 opposite the locking pin receptacle 46 of the respective holding part 20 in which he is included. Only if, as in figure 1, a very large pull-out force P on the Closing pin 14 is exerted, e.g. on the order of 20 kN, elastic deformation of the guideway 22 occurs by placing them in the area of the upper opening of the Cup profile spreads according to Figure 4. Then the locking ball 24 in the direction of the pull-out force P upwards be taken along by the closing surface 26.
  • FIG. 1 On upper end of the locking pin receptacle 46 an abutment plate 48 arranged, which according to Figure 3 by the tubular Housing 18 and the holding part 20 is positioned.
  • This Abutment plate 48 has a keyhole-shaped opening 50 on with a passage opening 50a for the closing mandrel 14 and an extension 50b.
  • the extension 50b is as can be seen from Figures 1 and 2, in the longitudinal direction of the Locking pin 14 of the ball 24 opposite. If the big one Pulling force P is exerted, the locking ball tries 24 through which between the closing surface 26 and the locking ball 24 occurring cam action initially dodge to the left and thus loads the control element 28.
  • the Self-locking of the locking ball 24 between the Closing surface 26 and extension 50b can be easily by appropriate dimensioning of the depth of the closing surface 26 and adjust the shape and size of the extension 50b. Self-locking is said to say that - if the locking ball 24 one time engagement with the lower boundary edge the extension 50b has found and still on the closing surface 26 abuts, the ball 24 no longer Has endeavored in the direction of the double arrow 30 to the left to avoid, but between the closing surface 26 and the lower edge of the extension 50b clamped. So there is no further force on the actuator 28 exercised over the locking cylinder 34 could strain its load-bearing capacity.
  • the balls 24 come not in the first place with the extension 50b and can therefore under compression of the respective helical compression springs 32 so far in the direction of arrow 30 to the left dodge until the locking ball 24 completely out of the Closing surface 26 dipped and the locking pin 14 completely can be pulled out. It is necessary that the Deformation elasticity of the guideway 22 and the spring force the helical compression spring 32 properly matched are in order to avoid the locking ball 24 Arrow direction 30 before evading upwards in To allow arrow direction 38.
  • the shape of the closing surface 26, the diameter of the locking ball 24 and the preload of the helical compression spring 32 are coordinated so that one normal opening of the lock after unblocking of the lock cylinder 34 of the lock bracket 10 with a small Extraction can be solved, on the other hand this pull-out force should not be too small, so not one unintentional falling out of the lock bracket from the Lock body can enter.
  • the abutment plate 48 next to the Abutment function also perform a securing function can by making the accessibility of the castle interior by drilling out the housing and then inserting it complicated by engaging elements; it also stiffens the lock housing against pull-out forces.
  • the holding parts 20 have the same shape can be trained. Nevertheless, the molded parts, as can be seen from FIG. 4, be designed with adapters, that allow you to plug them together. You can see in the Figure 4 a pin 60 and a pin receptacle 62. If the two identical holding parts within the lock housing 18 are put together, so the tenon of one finds Holding part 20 in the pin receptacle 62 of the other holding element.
  • the locking pin receptacles 46 are part of the respective holding part 20.
  • the facing ends the holding parts 20 also form a receptacle 64 for the Lock cylinder, so that it rotatably in the lock body 16 is held.
  • the fixing of the holding parts 20 in the longitudinal direction of the tubular lock housing 18 is carried out by Pinning at 66. It can be seen from Figures 1-5 that the Holding parts 20 are thin-walled, so that they are in essential only those necessary within the holding parts Define functional areas.
  • the positive reception of the Holding parts in the rectangular profile of the tubular Housing 18 is in the upper corners 68 through the edges of the cup profile and in the bottom area of the housing by the Stem 70 of the cup profile.
  • the elasticity of the Guide track 22 to prevent locking ball 24 from evading in the direction of arrow 38 by supporting the edges of the Cup profile on the side walls of the tubular housing can be set.
  • the arrangement of the key engagement slot 40 on the lower housing wall facilitates the handling of the Castle.
