Werkbock mit aneinanderklappbaren Beinen.Work trestle with legs that can be folded together.

Patentiert im Deutschen Reiche vom 25. Januar 1917 ab.Patented in the German Empire on January 25, 1917.

Die Erfindung betrifft einen mit zusammenschiebbarer Standbühne ausgestatteten Werkbock, der in bekannter Weise aus einem Dreibein besteht, das oben den Rohrschraubstock 5 o. dgl. trägt. Bei den bekannten Werkböcken sind die Beine mit dem Schraubstock in der Regel derart drehbar verbunden, daß sie aneinandergeklappt werden können. In den freien Enden der Vorderbeine ist die Stanclbühne abnehmbar befestigt, damit man sie von den Vorderbeinen abnehmen kann, bevor man die Beine aneinanderklappt. Dieses Abnehmen und Wiederanbringen der Standbühne ist nicht nur recht zeitraubend, sondem es ist auch das Weiterbefördern der losen Standbühne sehr umständlich, zumal die aus parallel zueinander verschiebbaren Stäben bestehende Standbühne zusammengeschoben etwa doppelt so lang ist wie in der Gebrauchsstellung. The invention relates to a work trestle equipped with a collapsible platform, which in a known manner consists of a tripod, which is above the pipe vice 5 or the like. In the known work stands, the legs are with the vice in the Usually rotatably connected in such a way that they can be folded together. In the The free ends of the front legs are attached to the Stancl platform so that they can be removed from the front legs before folding the legs together. This slimming and reattaching the platform is not only quite time consuming, it is it is also very cumbersome to move the loose standing platform, especially since it is off Rods that can be moved parallel to one another are pushed together is about twice as long as in the position of use.

Gemäß der Erfindung werden die Nachteile dadurch vermieden, daß die Verbindungsschienen zwischen den mit den Werkbockvorderbeinen in an sich bekannter Weise drehbar verbundenen Seitenschienen der Standbühne aus mehreren Gelenkstücken bestehen, die beim Gegeneinanderklappen der Vorderbeine ebenfalls gegeneinanderklappen. Die Seitenschienen legen sich z. B. in die Winkeleisen hinein, aus denen die Beine bestehen, und die Gelenkteile der Verbindungsschienen knicken zusammen und legen sich in den Raum, der zwischen den gegeneinandergeklappten Vorderbeinen des Werkbockes ohnehin vorhanden ist. Man braucht also die Standbühne nicht abzunehmen, und zusammengeklappt nimmt sie keinen besonderen Raum ein. Der zusammengelegte AVerkbock hat die Form eines dicken Stabes und kann von dem Arbeiter bequem über die Schulter gelegt werden-, so daß der eigentliche Schraubstock hinter der Schulter des Arbeiters schwebt, der den Stab mit seiner Hand festhält. Der Schraubstockbügel braucht nicht massiv zu sein, sondern kann aus zwei starken Blechwänden mit dazwischen eingeschlossenen Führungsstückeu für die Spindel usw. zusammengenietet sein. Die Beine können aus T-Eisen, die Seitenschienen der Standbühne aus Winkeleisen und die Gelenkstreben aus Bandeisen hergestellt sein, so daß der Werkbock verhältnismäßig leicht und bequem fortzuschaffen ist. Das Feststellen der ausschwingbaren Beine erfolgt z. B. mittels zweier Bolzen, von denen der eine als Lagerbolzen ständig stecken bleibt, während der andere als Fiügelschraube ausgebildet und leicht herausnehmbar ist. In der Gebrauchsstellung durchgreift die Flügelschraube das ausgeschwungene Bein und das zugehörige Auge im Schraubstockbügel, dagegen liegt nach dem Zusammenklappen der Beine die Flügelschraube derart neben der Beinschiene, daß diese gegen selbsttätiges Ausschwingen gesichert ist.According to the invention, the disadvantages are avoided in that the connecting rails between the work trestle front legs in a known manner rotatably connected side rails of the standing platform consist of several articulated pieces, which also fold against each other when the front legs are folded against each other. The side rails lay z. B. in the Put in angle irons that make up the legs and the joint parts of the connecting rails buckle and lie down in the space between the folded against each other The front legs of the work trestle are present anyway. So you need that The platform cannot be removed, and when folded it does not take up any special space. The collapsed AVerkbock has the shape of a thick stick and can be comfortably carried over the shoulder of the worker so that the actual vice hovers behind the shoulder of the worker who is holding the rod with his Hand holding on. The vise bracket does not need to be massive, but can consist of two strong sheet metal walls with guide pieces for the spindle enclosed in between etc. be riveted together. The legs can be made of T-iron, the side rails of the Standing platform made of angle iron and the hinged struts made of strip iron, so that the trestle is relatively easy and convenient to move. Noting the swing-out legs are made z. B. by means of two bolts, one of which is a bearing bolt constantly gets stuck, while the other is designed as a wing screw and can be easily removed. In the position of use, the wing screw engages through this curved leg and the corresponding eye in the vice bracket, on the other hand, lies after folding the legs, the wing screw next to the leg brace, that this is secured against automatic swinging out.

Claims

Fig. 3 the work trestle in section according to AB of Fig. Ι and 2 with the platform laid down,

Fig. 4 shows the lower part of the A-cradle in a front view with folded Legs.

The vice yoke i, in which the spindle 2 is guided, is with the bearing lugs 3 provided, in which the front legs 4 are rotatably supported. And turn the legs 4 made of T-irons or the like around the bolts 5. In the swung out Position the foot of the T-iron on the outside of the attachment 3, and above of the bolt 5 are bores of the rails 4 and the extension 3 in such a way one above the other one that by engagement of the wing screw 6 both firmly λ-erbunden \ verden (Fig. 1). In order to be able to swing the legs 4 into the mutually parallel position, you have to remove the screw 6. If you have then turned leg 4 into the central position and if you screw the wing screw 6 back in, it lies against the inside Rail 4 in such a way that the rail is secured against swinging out again. Rear the rear leg 8 is mounted in the approach 7 on the vise bracket in a manner known per se. With the free ends of the order legs 4, the angle rails 9 are articulated connected, and the angle rails are interconnected by hinge rails 10. Be the rails 9 with the hinged rails 10 folded down into the horizontal position (Fig. 3), they form the platform on which the worker can stand while working.

When the trestle is folded up, the rails 10 also slide at an acute angle together (Fig. 4).

In the rails 4 and 8 holes 11 can be provided in which by means of Hook 0. Like. A piece of cloth, leather 0. Like 12 attached \ verden \ verden serves as a support for tools (Fig. 3) and when the frame is folded up collapses by itself.

Pat ent claims ρ ρ odor:

:. Work trestle with legs that can be folded together and ■ collapsible ones attached to them Standing platform, characterized in that the connecting rails between the front legs with the work trestle (4) in a known manner rotatably connected side rails (9) of the v-standing platform from several Articulated rods (10) exist, which when folding together the .Workbock front legs also fold against each other.
