Description

10 15 20 25 30 35 458 220 The present invention has for its object to provide one tipping net construction as well as in construction and in the steering of the control element is simplified, and where in particular the the tipping sequence is facilitated without this reducing risk because it happens unintentionally.

The solution of this task is achieved by a tipping button. construction of initially described type son have they in claim 1.

Through the construction according to the invention, the tipping process can initiated by a pressure-operated shortening of the piston-cylinder the unit since the interlocking device secured in the mast upregulated. After straightening, the mast 1 is located one almost unstable equilibrium, which eliminates the need for piston-cylinder unit or the like. An insurance against unauthorized persons tipping is accomplished by arranging the interlocking mechanism inside the mast shoe which is designed as a box body. Two particular embodiments of the present invention offer additional benefits due to those described in more detail below the characteristics and modes of action.

A first further development solution consists in that one locking element is arranged on the detachable lid for the opening in the mast shoe and part of the interlocking mechanism, especially a handle. is secured resp. blocked in advance position at the simultaneously closed lid through the locking element and when the lid is open, it can be read 1 in a raised position directly or via an attachable extension rod in the mast shoe, especially by means of a push-pin connection and prevents the lid from closing in the area of the track element. (Fig. 1).

The in this case the lid provided with a closing device offers for the first possibility to secure the interlocking device unauthorized contact as the cover is provided with a built-in cylinder lock. and secondly ensures through the locking element that the lid can only be closed in against way Someone va, U1 10 15 20 25 30 35 458 220 regulatory position and that when the mechanism is upregulated a closure of the lid is prevented. The operator. that is not leaves the mast without closing the lid, is thus forced to i properly lock the interlocking mechanism.

The lid can also protect the access to it inside the nest shoe arranged the electrical equipment to a candlestick, and thus fulfill a dual function.

According to other advantageous embodiments, the handrails of the interlocking mechanism be coupled to an extension rod, which in the state of uplift is - especially at the bottom of a bolt connection - attachable 1 mast shoe. In this way, the servant concentrates on the position of the mast and is not during the raising or lowering of the mast to keep the regulating mechanism against the action of the spring.

The second further developing solution according to the invention consists of a shoe in the area of the particular eye bearing bracket designed lower stationary articulation point for piston-cylinder the unit has an opening through which a vertical mandrel upper end of a nanover lever of the interlocking mechanism passes, that the lower end of the piston-cylinder unit is articulated in the lever end in a movable point of attack - especially by a firing pin connection through one eye. that in interlock mode the point of attack at the lever end is above the lower point of reference for the piston-cylinder unit and that the lever in the upright position it is lockable until the downward piston cylinder the lower end of the unit in the fixed lower hinge point - especially by means of a push-pin connection through converging eyes. (Fig. 2 and 3).

The embodiment described above is operated on the following way: the piston-cylinder unit is connected to the end of the nanover but. which should not be able to be moved either manually or through body weight due to the selected gear ratio, after which the piston the cylinder unit is pressurized and extended and the locking mechanism is triggered, the piston carrying the foundation to the floor 458 220 10 15 20 25 30 35 4 the cylinder unit prevents unwanted tipping of the mast.

The lower coupling point of the piston-cylinder unit is now at the fixed lower articulation point - especially down the same insertion connection as between the piston-cylinder unit and the control lever - held. after which the piston-cylinder unit is reversed and shortened by pressure control. This is done according to the invention tipping of the mast and its controlled rerouting. Since' upregulation is only possible with the aid of the piston-cylinder unit and because the mast without establishing the insertion joint upon reversal will immediately be locked again. can at it the embodiment described here tipping the mast only takes place by proper operation of the piston-cylinder assembly. Härige ~ This provides increased safety against any incorrect operation.

According to a particularly advantageous embodiment, the interlocking the device may be characterized by a loop or coupling plate on the mast foot part of the upright mast passes through an opening in the mast shoe and for interlocking the upright the mast is held by a rule or latch. If interlocking device ningen, as described above comprises a simple handle and a lid provided with a locking element. In the same way is the combination is also possible with a protrusion protruding from the mast shoe lever end via a rod, as described above. wherein the piston the cylinder unit can be connected to the heater spirit for upregulation.

In a further embodiment as an alternative to the one above described, the interlocking device may be characterized in that a locking device arranged horizontally perpendicular to the control lever pin passes through elongated holes in the lower part of the mast passage and for interlocking the upright mast intervenes with its ends with recesses in the lower side edges of the mast foot part, by the regulatory mechanism. especially the rule or the heater can be fixed locked directly or indirectly - especially on a control rod the spring and transmits the spring force - by means of a safety pin in the inside of the mast shoe for interlocking the upright mast.

In this case, the control lever can be designed as a single-armed lever, which through the construction is simplified by 10 15 20 25 30 35 458 220 guide joints can be completely eliminated.

Although the control lever is usually not intended to be operated manually from the outside due to the selected spring force resp. the selected gear ratio, it is possible according to a drawn further development, that the interlocking mechanism in particular the rule or lever can be locked directly or indirectly - in particular on a rod which guides the spring and transmits the the force - by means of a safety pin 1 mast cone interior for adjustment of the upright mast.

In connection with a closable lid in the mast shoe, this is hereby raised safety even more against unauthorized lifting of the mast.

The upper pivot point of the piston-cylinder unit is preferably in the case of an upright mast arranged on the outside of the mast pipe part above the lower joint point, the corresponding the bearing eye can be arranged on a welded collar in the form of a pipe holders or on a rule implemented through the pipe. The larger the center displacement resp. the horizontal offset is towards the tipping point of the tipping mast. the easier it is to initiate rearrangement of the mast.

Take into account the size of the rivet offset of the tipping point the tipping in the above-mentioned first embodiment may can be started manually and thus one can eliminate one easily acting piston-cylinder unit. The piston-cylinder unit is - as is known in the art - designed as a portable device, which only if necessary is connected to the tipping mast and is equipped with its own printing system. especially with a hand punch. and your own control system for switching between extension and shortening and in particular a valve system to control mast tipping speed.
