Description

The invention relates to a device for releasing a key, in particular a locker key that is in the open position of the lock is held by a lock in the castle and only after unlocking the Lock in the closed position of the lock can be pulled out of the lock, being the lock is unlocked using a release medium.

Such devices are, for example, locker locks on sports or Recreational facilities known. These known release devices work with a card or coin as release medium, which is in the castle is introduced. Once the release medium is in the locking mechanism is introduced, the rotary movement to lock the locker Approved. The release medium then remains for the entire time, in which the locker is locked, inside the locker and can only after opening the locker again.

In modern sports and leisure facilities, the user of the facility is next to the pure use of, for example, the swimming pool is also offered use other services such as sauna and solarium. With swimming pools in particular, it has been found that the users the swimming pool hardly needs these additional services as they do not have any cash or anything else after moving Carry with you to the additional services as well To be able to use food and drink offers.

From DE-U-9209666 is a key for opening mechanical or Electromagnetic locks known, in the handle of which by means of a external interrogation unit identifiable without contact, for example, a transponder is arranged. Can in the transponder For example, a certain monetary value may be saved when in use various services or the purchase of food and drinks is automatically debited. It is also possible to use the To store services and the like on the transponder and when leaving the sports or leisure facility on the transponder to pay the saved amount. A disadvantage of this known system on the one hand, that no free choice of locker can take place because of the issue of the key to the user of the locker to be used and on the other hand that the issue of using a fastening strap provided locker key can not be done fully automatically.

The invention has for its object to provide a device of the type mentioned, which on the one hand allows a fully automatic output of the release medium with simultaneous free locker selection, and on the other hand allows the user to continue to use the release medium for the use of additional services and the like.

The solution to this problem is characterized in that the lock consists of a locking element forming the handle of the key and a holding element fastened to the lock and / or the door leaf and interacting with the locking element, the release medium being insertable into the locking element.

This inventive design of a device for release of a key, it is possible for the user to use one with a Lock provided device according to the invention after purchase any lock or locker of the release medium can choose, because all release media are identical and thus used to release any key still available can be. Because the user when entering the sports or leisure facility only the release medium, but not a corresponding one, with a Holding device provided key, it is possible to Output of the release media fully automatically, for example on one To run ticket machines.

In a preferred embodiment of the invention, the release media are as a transponder, i.e. as an electronically readable and writable memory for contactless data transmission, so that the user with the once acquired release medium, which after removal of the Key remains in the locking element designed as a key handle, also the other services without using cash or can use other means of payment. For this purpose it is possible to To assign transponders with a predetermined amount of money, for example or to save the services used in the transponder, which the user then exits when leaving the sports or leisure facility has to pay or which are debited from his account.

In a practical embodiment of the invention, the holding element is as formed around the locking element rosette. This configuration of the Holding element has the advantage that the locking element and thus the Key completely secured against manipulation by the holding element are.

In a preferred embodiment of the invention, the blocking element a housing in which at least one about a fulcrum pivotable locking arm provided with at least one locking lug is arranged that when not or not completely in the locking element introduced release medium, the at least one latch of the at least a locking arm through an opening in the housing of the locking element engages in at least one recess in the holding element. Through this Design of the locking element according to the invention ensures that the key can only be removed from the lock if that Release medium has been fully inserted into the locking element. At only a partial introduction of a release medium is the rotation of the Key blocked.

In a practical embodiment, the housing of the Locking element two each pivotable about a pivot point a locking nose provided locking arms arranged. By this doubling the number of locking arms and locking lugs becomes a more secure and tilt-free hold of the locking element in the holding element guaranteed. Around the holding force of the locking lugs in the recesses of the holding element reinforce, is between the two locking arms at least one of the locking arms pushing apart spring element arranged.

A particularly secure hold of the locking element in the holding element is one practical embodiment of the invention achieved in that each locking arm than in each case pivotable about an approximately centrally arranged pivot point is formed two-leg rocker arm, the at least one Locking lug per locking arm pointing outwards at a free end of one leg each locking arm is arranged, but preferably on both free Leg ends of each locking arm each have an outwardly facing locking lug is arranged. By designing the locking arms as about an approximately center arranged pivot pivot rocker arm with free on both Leg ends arranged locking lugs will double the Locking element in the holding element allows, which to which the Insertion opening for leg ends removed from the release medium arranged locking lugs a rotation of the key or Prevent the blocking element when the release medium is not used and the on the leg end near the insertion opening for the release medium arranged locking lugs a rotation of the locking element during the Prevent insertion of the release medium into the locking element, as well as at the release medium used pulling out the release medium prevent.

The spring element that pushes the two spring arms apart preferably arranged above the fulcrums of the two locking arms by spreading the locking arms in the pulled state of the Key the setting of the release medium in the locking element support. To ensure that the locking lugs as protection against rotation for serve the key, the recesses in the holding element for receiving the locking lugs as arranged in the axial direction of the holding element Longitudinal grooves formed. By engaging the locking lugs in this Longitudinal grooves are not possible to use the key without a release medium Twist locking element within the lock. The longitudinal grooves are closed at the front by a circumferential edge to prevent manipulation to prevent the locking lugs.

According to a practical embodiment of the invention, it is proposed that that on the free end face of the holding element only in Twist range of the key an undercut for the locking lugs forming edge is formed. By reducing the margin to the Rotation range of the lock, it is possible to keep the holding element as small as possible and partially open to design, so that the key when inserted Release medium can be easily operated via the locking element.

Furthermore, the invention proposes that on the Housing base of the locking element, a guide is formed on the a locking bolt slidably arranged in the longitudinal direction of the locking element is.

Figures 1a, 2a and 3a each show a longitudinal section through a device for releasing a key 1 in the open position a lock 2 is held in the lock 2 by means of a lock 3. Such devices are used for example in locker locks Bathing establishments and similar sports facilities used. To close the Locker lock and removal of the key 1, it is with these devices necessary to unlock the lock 3 by means of a release medium 4. At a later opening of the locker lock using the key 1 will Release medium 4 returned to the user and the key 1 again held immovably in lock 2 by means of the lock 3.

As can be seen from the pictures, the one shown Embodiment the lock 3 from a fixed at the castle 2 or not Door leaf shown fastened holding element 5 and one in the Holding element 5 arranged, forming the handle of the key 1 Locking element 6. A great advantage of this device compared to the stand The technique is that the locking element 6 has a receiving space 6a for the release medium 4. Because of this configuration remains the release medium 4 with the locker locked and the key removed 1 by the fixed connection with the locking element 6 at the user, so that the latter the release medium 4 for the use of further services and the like can be used in the sports and leisure facility, if that Release medium 4, for example, as a transponder, that is, electronically readable and writable memory is formed.

The locking element 6 consists of a housing 7 and two on the Housing base 7a arranged locking arms 8, which on the Housing base 7a arranged pivot points 7b are pivotable. How 1a, 2a and 3a can be seen, the receiving space 6a for the release medium 4 between the housing base 7a and the the housing base 7a arranged locking arms 8 formed. The Latching arms 8 are mirror-symmetrical as two-leg rocker arms the pivot point 7b in the longitudinal extension of the locking arms 8 seen is arranged approximately in the middle. At the two free ends of the legs of each locking arm 8 is an outwardly facing locking lug 8a and 8b integrally formed by the corresponding when pivoting the locking arms 8 Openings 7c in the housing 7 can emerge from the housing 7. Between the locking arms 8 there is a spring element 9 above the pivot points 7b arranged through which the upper legs of the locking arms 8th be pushed apart.

The key 1 is at the end opposite an insertion opening 7d the housing 7 attached to a key holder 10. To the Interact with a slidable on the housing base 7a Arranged locking bolt 11 has the key holder 10 from Key 1 facing recess 10a.

As can be seen from the figures Fig. 4a and 4b, is on the Housing base 7a a guide designed as a protruding cam 7e formed, on which the locking bolt 11 shown in Fig. 5 Longitudinal direction of the locking element 6 is slidably arranged. In the lock bolt 11 a receiving pocket 11a is formed in which a spring 12 is arranged is through which the locking bolt 11 in the direction of the recess 10a Key holder 10 is spring-loaded. The locking bolt 11 is at illustrated embodiment is substantially T-shaped, so arranged on the guide 7e that the vertical leg 11b of the Locking bolt 11 can be inserted into the recess 10a of the key receptacle 10 is. Furthermore, a through opening 7f is formed in the housing 7 serves to pull a tether.

As can be seen in particular from Figures 6a and 6b, the End face 2a of the lock 2 guide pins 2b arranged at locking element 6 fully inserted into the holding element 5 (FIGS. 1a and 2a) protrude into the recess 10a of the key holder 10.

For locking the locking element 6 within the holding element 5 and to turn the key 1 without release medium 4 in the lock 2 in the To prevent open position are in the inner lateral surface 5 a Holding element 5 formed as longitudinal grooves 5b recesses, into which the locking lugs 8a and 8b of the locking arms 8 of the locking element 6 engage can. Those formed in the inner lateral surface 5a of the holding element 5 Longitudinal grooves 5b are to the free end face 5c of the holding element 5 by a closed inwardly projecting edge 5d to prevent manipulation of the To prevent locking lugs 8a and 8b.

In particular with reference to the figures Fig. 1a, 2a and 3a is below the operation of the release device described above of the key 1 described.

Fig. 1a shows the device in the open position, in which the key 1 over the lock 3 consisting of the holding element 5 and the locking element 6 cannot be rotated and is not pulled out in lock 2. That as the locking element 6 and the lock 2 surrounding rosette trained holding element 5 is there so attached to the lock 2 or the door leaf that the key 1 in Fig. 1a open position shown by the lock 2 against pulling out is secured from the castle 2.

To prevent the key 1 from being the key handle Locking element 6 can be rotated within the holding element are in the inner lateral surface 5a of the holding element 5 formed longitudinal grooves 5b, in which engage the upper locking lugs 8a of the locking arms 8 of the locking element 6. The interaction of the locking lugs 8a with the longitudinal grooves 5b thus provides a pure anti-rotation for the key 1 in the lock 2. In this in 1a shown position, it is therefore not possible to remove the key 1 pull the lock 2 out, the key 1 in the lock 2 twist.

The front view of FIG. 1 a shown in FIG. 1 b shows as in FIG the open position the locking element 6 and thus the key 1 in relation to those formed in the inner lateral surface 5a of the holding element 5 Longitudinal grooves 5b is arranged.

In the position shown in FIG. 2a there is a release medium 4 in the receiving space 6a of the locking element 6. By forming the Locking arms 8 as two-leg rocker arms, the locking arms 8 are complete inserted release medium 4 so arranged within the housing 7 that the locking lugs 8a and 8b do not come out of the openings 7c of the housing 7 stick out. Due to the lack of engagement of the locking lugs 8a and 8b in the Longitudinal grooves 5b of the holding element 5, it is now possible to use the locking element 6 and thus to turn the key 1 in the lock 2, since the locking lugs 8a and 8b bear against the inner lateral surface 5a of the holding element 5.

The front view shown in Fig. 2b shows that in the illustration 2a the hatched locking bar just before the horizontal Close and pull position.

To prevent that when inserting the release medium 4 in the Recording space 6a of the locking element 6, the release medium 4 only as far in the receiving space 6a is inserted until the upper locking lugs 8a Detent arms 8 disengage from the longitudinal grooves 5b are also on the Insertion opening 7d near free leg ends of the locking arms 8 locking lugs 8b arranged, when inserting the release medium 4 to the outside in the Longitudinal grooves 5b are pressed until the release medium 4 is completely in the Recording space 6a of the locking element 6 has been introduced, as the Figure Fig. 1c can be seen.

Fig. 3a shows the locking element 6 and the key 1 in the Pull position or closed position of the lock 2. As from the illustration 3b, the blocking element 6 is now in the position in FIG. 2b indicated end position, in which the key 1 from the lock 2nd can be deducted.

In this withdrawal position of the locking element 6, the locking bolt 11 is by the spring 12 arranged in the receiving pocket 11a so far upwards pressed that on the one hand the vertical leg 11b of the locking bolt 11 fully engages in the recess 10a of the key holder 10 and on the other hand, the horizontal leg 11c of the locking bolt 11 is form-fitting bears between two shoulders 8c formed on the locking arms 8, so that when the locking element 6 is completely pulled out of the holding element 5 Latching arms 8 do not release the release medium 4 into the interior of the Locking element 6 can be pressed.

In the position shown in Fig. 2a, the vertical leg 11b of the Locking bolt 11 is not yet completely in the recess 10a Intervene key holder 10, because in this position the Guide pins 2b of the lock 2 in the recess 10a Insert key holder 10.

Advantageous in the illustrated embodiment of a device for release A locker key is on the one hand that the user after purchasing the Release medium 4 has the free choice of which locker he wants to use each release medium 4 is suitable for releasing each lock 3. About that it is also 4 when using transponders as release medium advantageous that the transponder held firmly in the locking element 6 can continue to be used to use other services and / or purchase food and beverages. For this it is for example possible when purchasing the release medium 4 - which is fully automatic can be done by a pay machine - a certain amount in the To have the transponder stored, which is then gradually added to the Use of various services and / or the purchase of food and drinks are debited. It is also conceivable in the transponder to save only the use of the various services which then to be paid when leaving the sports or leisure facility or from User’s account.

In order to get the release medium 4 back, the blocking element 6 with the key 1 back into the matching lock 2. For this is either on the locking element 6 or the key 1 one Labeling, which is also located on lock 2 or on the cabinet. The release of the release medium and the unlocking of the lock 2 takes place in the order of the figures Fig. 3a, 2a and 1a. At the The locking element 6 is inserted into the lock 2 according to FIG. 3a Locking bolt 11 through the guide pins 2b of the lock 2 from the Cutout 10a of the key holder 10 is pushed out again. By this displacement of the locking bolt 11 also becomes the form-fitting system of the horizontal leg 11c on the shoulders 8c of the locking arms 8 canceled so that the locking arms 8 can be pivoted inwards again. After turning the locking element 6 or the key 1 back in the position shown in Fig. 1a, it is now possible that Release medium 4 to the rear from the insertion opening 7d of the housing 7 pull out. Due to the tiltable mounting of the locking arms 8 the legs of the locking arms 8 which are close to the key are pivoted inwards, whereby the leg located near the insertion opening 7d Move locking arms 8 apart and release the release medium. To complete removal of the release medium grab those nearby the insertion opening 7d located locking lugs 8b of the locking arms 8 in the Longitudinal grooves 5b in order to rotate the locking element 6 or To prevent key 1.

Figures 7a to 8b show two embodiments of Holding elements 5 shown. The in Figures 7a and 7b shown holding element 5 corresponds essentially to that in the Figures Fig. 1a, 2a and 3a shown holding element. From the Illustrations can be seen that in the illustrated embodiment, the Holding element 5 only in the rotation range of the locking element 6 or Key 1 on the end face 5c has the edge 5d and also the full Height is formed. Through this formation of partial recesses 5e in the body of the holding element 5, the access and use of the Locking element 6 facilitated by the user.

In the second embodiment shown in Fig. 8a and 8b Holding element 5 has the holding element 5 only approximately half the height of the in 7a and 7b shown holding element. With this shortened Embodiment of the holding element 5 is the anti-rotation of Locking element 6 within the holding element 5 only through the key Latches 8a of the locking arms 8 causes. To in this embodiment too prevent the release medium 4 from only partially entering the blocking element 6 used and after turning the locking element 6 from the Open position pulled out of this are inside Shell surface 5a of the holding element 5 shortly before reaching the Pull-off position formed additional longitudinal grooves 5b into which the locking lugs 8a intervene if there is no release medium in the blocking element 6, as shown in Figs. 9a and 9b.
