- This flange-like coupling part 43 is in cross section advantageously rectangular and also based on its end face provided with oblique guide surfaces 43 '.
- the claw elements 41, 42 are at the front end of the drive rod 32 arranged approximately parallel to each other and thereby form a pincer.
- the claw elements 41, 42 have a spring member 45 on the back assigned, which generates such a torque on the claw elements, that they are pushed in at the front, but only until they are one Take up position approximately parallel to each other.
- the spring member 45 is preferably composed of several disc springs or the like, which are held by the drive rod 32.
- Fig. 3 illustrates the lateral insertion of the linear drive shown in dashed lines 30 'in the bracket 28 attached to the slide lock 20
- Linear drive 30 is at the front end of its cylinder 33 with a cross to this extending guide element 36, which is outside protrudes all around to this cylinder 33.
- this guide element 36 is in a funnel-shaped opening 29 of the holder 28 and subsequently further into a guide groove 38 inserted in the cross-sectionally U-shaped holder 28.
- the guide groove 38 is dimensioned such that the guide element 36 is held approximately form-fitting therein.
- the funnel-shaped Formation of the opening 29 enables comfortable insertion of the cylinder 33 in the holder 28, in particular also when this cylinder is operated by a manipulator, not shown.
- Stroke limiting pin 56 limits the stroke the slide unit 25 with respect to the closed position of the slide closure.
- the contact surface 42 'of the claw element 41, 42 is advantageous for snapping the latter properly convex, as shown in Fig.5.
- the drive rod 32 is in a stroke range during of the company withdrawn.
- the bracket 28 By forming the bracket 28 on their inside 28 'corresponding to the claw elements 41, 42, 28 "creates a further advantage according to the invention.
- the inside 28 'of Bracket is in the area of the coupling position shown opposite Inside 28 "in the operating position of clutch 40 to the outside added. This causes the claw elements 41, 42 to lock through the inside 28 "in the stroke area during operation as in Fig.1 is clarified.
- the inner sides 28 are therefore parallel to the direction of displacement at a short distance from the outer surfaces of the claw elements 41, 42 arranged, the latter hereby secured against disengagement are.
- the linear actuator 30 in the coupling position without any additional Manipulation and in any stroke position of the drive rod 32 be pulled out transversely to the direction of displacement.
- the claw elements 41, 42 are for this purpose on the drive rod 32 with parallel to each other and in the same direction as the pull-out direction of the linear drive extending pivot axes 44 arranged. While pulling out of the linear drive 30, the two claw elements 41, 42 slide in the snapped State transverse to the longitudinal extension of the push rod 27 on the Coupling part 43 until they are released laterally from this coupling part 43.
- FIGS. 6 and 7 show another embodiment variant of an inventive one Coupling 60, which in the coupled state shown Push rod 27 of the slide unit 25 with the drive rod 32 of the linear drive 30 connects.
- Push rod 27 of the slide unit 25 with the drive rod 32 of the linear drive 30 connects.
- slide fastener 50 provided, which serves to receive and hold the linear drive 30, for this purpose at the end in this holder 50 a transverse guide groove 38 and approximately in this form-fitting insertable guide element 36 on the linear drive 30 is present.
- the coupling 60 has a coupling part arranged on the push rod 27 and a cooperating coupling part on the front End of the drive rod 32.
- the coupling part on the drive rod 32 is formed from a coupling sleeve 61 attached to the latter, which on the inside has a recess 61 'which is rectangular in cross section has which is open laterally according to Figure 7. Furthermore, are in this Sleeve 61 formed on the inside transverse grooves 62. Furthermore is on the side of this Sleeve 61 a pin 69 engaging in a longitudinal groove in the holder 50 intended.
- the coupling part on the push rod 27 has one in this recess 61 'matching central pin 37 and two on this on one axis 66 approximately radially pivotable pawls 63, each of a spiral spring 64 mounted on the pin 37 in a starting position - like shown - are pressed.
- These pawls 63 are each in the coupled state coupled into one of the transverse grooves 62 of the sleeve 61, such that this sleeve 61 with its front inwardly projecting ring part 61 "in the axial direction seen between these pawls 63 and an end stop surface 27 'of the push rod 27 is held. In this engaged position can the push rod 27 and with it the slide unit 25 from the drive rod 32 be moved back and forth.
- the linear drive 30 When disengaging, the linear drive 30 can be in any stroke position the push rod 27 transversely to the direction of displacement of its drive rod 32 be pulled out. From Figure 7 it can be seen that this Sleeve 61 through the one-sided open design of its recess 62 'and released through the lateral opening 29 of the bracket transverse to the axis of displacement is.
- the invention is sufficiently demonstrated with the illustrated embodiment. However, it could be carried out in a different construction. So could just be a tiltable claw element and opposite one mutual stop surface provided for centering the two coupling parts his. In principle, this claw element could also be in a longitudinal groove engage with a stab at the end of the push rod 27.
- the coupling part with the claw elements could just as well on the push rod of the slide unit, while the corresponding one Coupling part with the flange-like design on the drive rod of the Linear drive can be provided.
