TITLE NAME

Rohfei 1 clamping board for clamping wet wild raw fei 1

DESCRIPTION

The invention relates to a Rohfei 1 stretching board for drying, in particular, fur, rabbit and similar skins, whereby a ladle element is arranged so that it can move in the longitudinal direction between lateral stretching bars with wedge surfaces. By stretching the fresh, still damp skins, they are guaranteed to dry in a completely smooth, wrinkle-free form. This creates essential prerequisites for the storage and further processing of the skins.

Such tensioning devices are therefore used by hunters, trappers, in fur farms, by rabbit breeders, etc. A wide variety of designs are known, from the simple branch fork that the hunter or ^a paI1enstler can cut in the forest or straw filling that can be used for a rabbit

There are almost always ready-made and reusable devices available. A simple branch fork or similar primitive device may be sufficient in individual cases. However, such devices are not suitable for commercial use or for ^hunters and trappers.

A clamping board for furred game hides is known to hunters in general and from the hunting literature - for example R. Blase, "The Hunter's Examination", published by J. Neumann, 1965, page 362 - in which a wedge piece is arranged so that it can move in the longitudinal direction between two lateral clamping strips with wedge surfaces. The inner edge surfaces of the clamping strips are each provided with a longitudinal groove and the outer edge surfaces of the wedge piece are each provided with a spring which can move in the longitudinal groove of a clamping strip. By inserting the wedge piece more or less far between the clamping strips, these can be spread more or less far apart. This means that within a certain range

j Limits an adaptation of the clamping board to different

Sizes of the bellows possible* The bellows is pulled over the clamping board and stretched quite long.

The lips and nose are attached to the board with nails.

si The hind legs are also fully extended

and fastened to the board with nails. The front legs and the tail, which is sharpened to the tip, are

» kept apart by paper strips attached to the

stick to the moist inside of the skin.

The clamping of a bellows on such a clamp

board is very complicated and time-consuming. In addition, there is the disadvantage that a bellows always lies unevenly on the wedge-shaped clamping board, regardless of its natural shape.

is stretched so that the chest area is too loose and the back area is stretched too tightly. Removing the dried, hard bellows from the clamping board is also complicated: you have to use a suitable object to push the wedge back through the front opening of the bellows between the clamping bars before the clamping bars can be pulled out of the bellows. i Despite all the advantageous simplicity of these wooden clamping boards, they have the disadvantage that I when wedged into a bellows, a spring of the wedge piece can easily break off or a groove of a clamping bar can break out. Then the clamping board is no longer usable. \

The invention is therefore based on the object of creating a rawhide stretching board for drying, in particular, fur pelts, rabbit pelts and the like, whereby the disadvantages of the known stretching devices are largely eliminated.

To solve this problem, the invention is based on a clamping board with the features of the preamble of claim 1.

The stated object is achieved according to the invention in that such a clamping board has the features according to the characterizing part of claim 1. Further features of the clamping board according to the invention emerge from claims 2 to 5.

Fig. 5 shows a cross section through the assembled clamping board in the area of line B-B as per Fig. 1, 2 and 3.

The Rohfei 1 clamping board according to the invention consists essentially of an elongated base plate 1, a cover plate 2 with the same outline shape and two

Tension bar pairs 3, 4. «

The base plate 1 and the cover plate 2 have a matching shape, a head part 1a or 2a that tapers in a wedge shape from both sides towards the middle, to which a parallel body part 1b or 2b is connected. The clamping strips 3, 4 each have a T-shaped cross section and are arranged with their webs 3a, ka between the base plate 1 and cover plate 2 so that they can move laterally. One pair of clamping strips 3 extends over the head part 1a, 2a and the other pair of clamping strips 4 over the body part 1b, 2b of the clamping board.

I The tensioning elements extending over the head part 1a, 2a *

strips 3 are each with their head end at the end of the head 1a of the base plate 1 to be perpendicular

Axles 3b running through the chipboard laterally | pivotally mounted· The ones running over the fuselage part 1b,

Transition from the head part 1a to the body part 1b of the base plate 1 with a guide rail 5 arranged transversely to the longitudinal axis and a guide rail 6 arranged transversely on the base plate 1 in the rear area, parallel to each other and laterally movable in a forced guide.

For the spreading movement of the clamping strips 3, k , a pull rod is mounted on the base plate 1 in the longitudinal center between lateral guide jaws 1c so that it can move in the longitudinal direction. A clamping wedge 8 is arranged on it in the area of the head part 1a and three clamping trowels 9 are arranged at equal distances from one another in the area of the body part 1b with their wedge tips aligned towards the rear end of the clamping board. The clamping wedges 8, 9 lie flat between the base plate 1 and the cover plate 2. They are as thick as the webs 3a, k of the clamping strips.

Wedge abutments 10, 11 interacting with the clamping wedges 8, 9 are provided in the corresponding positions on the webs 3a, ha of the clamping strips. To return the pairs of clamping strips 3, k from the spread position, they are connected to the pull rod 7 by movable links 12 via the clamping wedges 8, 9.

For the axial movements of the pull rod 7, a screw thread is provided at its rear end, which engages with a clamping screw 14, which is fixed in the longitudinal center at the rear end of the base plate and rotatably mounted in the axial direction. The pull rod 7 is shorter than the base plate 1, whereby its rear end is designed as a tube with an internal thread. At the rear end of the base plate 1, a metal bracket 15 is arranged as an abutment for the clamping screw 14, which surrounds the base plate 1 in the plate plane.
