Definitions
- the invention relates to a drawbar for a machine device to be moved, in particular a sausage clip machine according to the preamble of claim 1.
- a drawbar for industrial trucks emerges which has a drawbar shaft.
- the tiller shaft is connected at one end to a vertical steering shaft mounted in the frame of the conveyor and at the other end to a tiller head, on which actuators for operating the conveyor are arranged. It is further provided that at least one joint with an essentially vertical axis of rotation is present between the tiller head and the tiller shaft and that a gear is arranged between the tiller head and frame such that the tiller head is given an ergonomic orientation when the tiller is in a position from the central position.
- a collapsible cart can be found in German Offenlegungsschrift 195 34 974, which has a pivotable platform, a pivotable handle and collapsible and adjustable tube arrangements in order to adjust the cart to an extended or retracted position.
- the cart can be used as a two-wheeled hand truck or as a four-wheeled cart.
- the reversible locking of the towbar unit in both the use position and the storage position ensures that the desired functionality does not dissolve by itself in both positions and that the towbar unit can therefore move out of the storage position independently, for example.
- the first towing bar element is at least partially telescopically insertable into the second towing bar element.
- the first and the second towing bar element are each designed as a tube, at least in their telescopic area, whereby preferably the outer diameter of the first tow bar element corresponds at least approximately to the inner diameter of the second tow bar element.
- these can have any shape, provided that the functionality of the drawbar according to the invention is not impaired by this.
- the first tow bar element can be telescopically inserted into the second tow bar element from the use position into the storage position.
- one of the two towing bar elements, preferably the second towing bar element can be firmly connected to the frame of the machine device to be moved.
- one of the two towing bar elements preferably the second towing bar element
- the second towing bar element it is not necessary for the second towing bar element to completely enclose the first towing bar element in the storage position, since, for example, the attachment of the second towing bar element to the machine device can take place in such a way that that part of the first towing bar element which is not located inside the second towing bar element , is received in a recess on the machine device to be moved.
- the locking recesses can be formed by through holes in the respective tow bar element.
- the locking recesses are formed by through holes in the tow bar unit, into which sleeves for sealing the through holes are preferably inserted tightly.
- the locking device To facilitate the actuation of the locking device, provision can furthermore be made for the locking device to have an actuating element which is connected to the locking element and which, together with the locking element, is reversibly movable into a locking position and a locking release position.
- the locking element can be moved in any direction. Simple and safe operation can be achieved in that the movement of the locking element is at least approximately radial to the longitudinal extension of the tow bar unit. As has already been mentioned above, to simplify the pulling movement it can be advantageous if the tow bar unit has a handle at its gripping end. This can preferably be offset from the longitudinal extent of the tow unit.
- the reciprocating movement of one tow bar element relative to the other tow bar element can be limited by the interaction between the locking element and locking counterparts. However, there is basically the possibility that the tow bar element to be moved is moved beyond the respective position. In order to prevent this, it can furthermore be advantageous if the movement of one towing bar element relative to the other towing bar element is limited by means of stops.
