Manually operable locking device

Abstract

A locking device for releasable locking with a counter body, having a base body, which is connected together with an add-on element and a connection element, and actuation means. One or more slides are fastened to the actuation means, which exert a relative movement to the locking device, whereby the slides are able to be brought into contact with the locking means and these can be transferred into a counter geometry of the counter body. Here, the actuation means remain in their respective position due to the return springs of the locking means and of the tension resulting therefrom as well as of a frictional resistance between locking means and slides. An automatic securing device is provided as secondary securing, designed as a spring-loaded securing bolt for securing the position of the actuation means and prevents unintentional opening of the locking device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) The locking device shown in FIGS. 1 and 2 is used to releasably lock a counter body.

(8) The locking device 1 has a base body 2, which is connected together with an add-on element 3 and a connection element 4, preferably by means of screws. Moreover, the locking device 1 has an actuator 5 that is connected to a securing device that has a spring-loaded securing bolt 10. This is releasable on an external side of an add-on element 3 and arranged in a manually operable manner. The actuator 5 can be moved relative to the base body 2 in the longitudinal direction.

(9) Furthermore, the actuator 5 has protruding slides 6 on the side remote from the securing device 3, thus on the side facing the base body 2, in the axial direction of the actuator 5. These slides 6 are fixedly or movably connected to the actuator 5. Each slide 6 has an inclined surface form pointing towards the respective lock 7. The lock 7 is held in position by associated return springs 9, preferably pressure springs in accordance with FIG. 1.

(10) The base body 2 can be detachably connected to a counter body 8, shown in FIG. 3. The connection element shown in FIG. 4 has recesses 11, into which the slides 6 can engage in the case of actuating the actuator 10, as is shown in FIG. 2 in the closed state of the locking device 1. Naturally, the slides 6 can again exit the recesses 11 in the case of unlocking, as is shown in FIG. 1. in the opened state of the locking device 1.

(11) In the exemplary depiction in accordance with FIGS. 1 and 2, two slides 6 are available, wherein, however, more than two slides may also be available.

(12) The locking device 1 can also be connected with the counter body 8 shown in FIGS. 2 and 3. The counter body 8 has a circumferential groove 12, into which the locking 7 means penetrate for locking. In addition to this, the base body 2 has a blind hole or a through-hole 13 into which the counter body 8 can at least partially penetrate and thus the lock 7 can be compressed in the radial direction into the groove 12.

(13) The moveable lock 7, for example in the form of a sphere, is provided in the base body 2. The lock 7 is arranged in a hole of the base body 2, wherein the hole is connected to the recess 11. The slide 6 protrudes into this recess 11, said slide being fastened to the actuator 5 in a mechanically fixed or moveable manner, or alternatively being part of the actuator 5.

(14) In FIGS. 1 and 2 the locking device 1 is shown in a position in which it is connected to the counter body 8. The counter body is arranged in the through-hole 13. The actuator 5 is located in a locking position in accordance with FIG. 2, in which the slides 6 of the actuator 5 are in contact with the lock 7. The slides 6 compress the lock 7 into the locking position. In this locking position, the lock 7 engages into the groove 12 of the counter body 8.

(15) Below, the connection process will be explained in detail, wherein it proceeds from the position depicted in FIG. 1, in which the locking device 1 is not connected to the counter body 8.

(16) In the position depicted in FIG. 1, the actuator 5 is located in the unlocking position, in which the actuator or the slides 6 of the actuator 5 are not in contact with the lock 7.

(17) So that a connection or locking between the locking device 1 and the counter body 8 is produced, the user must position the locking device 1 on the counter body 8. The user must subsequently exert a force on the actuator 5, which displaces the actuator in the axial direction 1 relative to the base body 2 and thus into the locking position.

(18) In the locking position, the slides 6 of the actuator 5 are in contact with the respective lock 7. In particular, the slides 6 compress the lock 7 in the radial direction out from the base body 2. Since the counter body 8 is arranged in the through-hole 13, the lock 7 engages at least partially into the groove 12 of the counter body 8.

(19) A connection and locking between the locking device 1 and the counter body 8 can be carried out by the engagement of the lock 7 into the groove 12. Accordingly, a connection and locking between a first component can be carried out, such as for example the wheel rim, which is connected to the locking device 1 and a second component, such as for example a wheel retainer or wheel hub, which is not depicted.
