The invention relates to a work stand which can be used in the production of λ'οη footwear, which has the purpose of and labor saving the individual work processes and their incidental measures simplify and promote.

In the manufacture of footwear, a device is usually used with their help with stretching or pulling them over

ίο the upper leather or upper is carried out. The device consists of a frame provided with a foot, on the upper part of which a two arms forming cross piece is rotatably arranged. At the far end of each arm is a holder for the workpiece attached. The arms can be fastened by means of a bolt or tooth ' locked can be determined or released by moving a pedal lever. Here but this device only for two workpiece

ao holder is set up and this and the arms can only rotate at the same time, it comes it often occurs that, in the case of unequally skilled workers, the one worker on the termination has to wait for the other worker's work, thereby wasting a lot of time. If therefore the workers do not keep pace with each other in the execution of their part of the work, there is a regular loss of time between the completion of the work of one and the other Continuation of this work by the other worker. "

According to the present invention, these disadvantages are eliminated or to a small extent restricted. In the same, several arms carrying the holder or the like become independent arranged rotatable and lockable from one another, in such a way that three, four or a greater number of arms can be used as desired. The arms can radial, rotatable around an upright by means of hubs Post o. The like. Be arranged and determined by suitable means in front of the workers who do not change their place or released.

The work stand is in an exemplary, expedient embodiment the drawing illustrates; in the same: Fig. ι is a side view of the stand with partial representation in section. Fig. 2 is a plan view.

The upright hollow shaft a ¹ , which is circular in cross section and on which the four individual swivel arms b are rotatably arranged by means of their hubs b ^{1, is} attached to a suitable base plate α. The hubs b ¹ are arranged one above the other and can be set up with ball bearings or the like to reduce friction. The outwardly or upwardly directed end of each arm b is also held by a strut b ² which, in the same way as the arm b, rotatably surrounds the shaft a ¹ with a hub b ^s.

On the upper end of the shaft a ¹ , a table top c can be fastened by means of the screws c ¹ or in some other way, which table top can be used to hold and prepare tools, devices, materials. The table top c is provided with an upper edge,

Claims (1)

in order to prevent the objects on the plate from rolling down or sliding down when the arms b are rotated. The hubs b ¹ or b ^{s of} the individual arms b and struts fc ² can also have lower or upper pin lugs with which they interlock in order to make the shaft a ¹ unnecessary. The top of each arm b is in ίο arranged at such an altitude as they usually require the individual work processes and is suitable for attaching the holders for the wooden or iron strips at the ends of the arms b. Each swivel arm b can be influenced by a spring and in one of the openings (notches) provided in the wall of the hollow shaft a ¹ in a suitable position engaging bolt d or the like workers located around the stand can be detected or released. In the embodiment shown, the bolt d is moved by the hand lever d ¹ , which is connected to the bolt d by a rod d ^% and an angle lever d ^s. When arriving . ' lift the hand lever d ¹ , the angle lever d ^s mounted in the lower part of the arms b is rotated about its pivot ^{d i} , thereby pulling the bolt d back out of the opening in the wall of the hollow shaft a ¹ and disengaging it, whereupon the arm b can be freely rotated around the shaft a ¹ and can be determined in a different position in the same way. The arms are free to rotate within their associated and the location determining its finding notches in the shank a ^1, the base plate can α with perforated feet α ² be provided to the work loading stand on the floor by means of bolts. consolidate to. can. The 'not shown holder for the strips o. The like. Are fixed in any suitable manner in the bushes b ^x at the upper ends of the arms. The work stand described above enables uninterrupted ■ management of the various jobs, etc. by the workers; the one worker who to assemble the upper leather or upper and attach the insole is completely unhindered by the worker who wears the upper leather over the Lasts tensioned and fastened. If necessary, the former is e.g. B. able to two To prepare shafts for the worker performing the clamping or vice versa, the the latter can prepare two upper leathers for the worker, of which the fastening and the heel is nailed onto the upper leather after it has been stretched in exactly the right position. if two arms are covered with joined leather upper, so are the other two Arms available to the worker who did this job. Are three arms in the occupied, one arm is still available to the named worker Disposal. This is to avoid the workers waiting for each other. In an equally advantageous manner, the work stand can except for the tensioning of the Shafts or the upper leather also for the other work processes in the manufacture of Footwear used to through appropriate distribution of work stages and Transferring work from one worker to another is a time saver to win. For example, also for the processing of the soles, for which also that Flattening, etc. and covering and leveling the crack at the edge of the outer surface belongs to the sole. The holders which carry the workpieces and are to be fastened in the bushes b are set up in accordance with the various devices. Patent-Α ν saying: Work stand for the manufacture of footwear, characterized in that the swivel arms (b, b ² ) carrying the workpieces can be adjusted and fixed (d ^v , d-, d ^s , d, a ¹ ) independently of one another. 1 sheet of drawings.
