The invention in question concerns a combination tool of the type specified in the introduction to the patent requirements.

The purpose of this invention is to solve various problems associated with, among other things, the handling of goods vehicles. Among these may be releasing trailer couplings, opening "hanging doors", scraping ice off the edges of lorry platforms, loosening and'tightening straps, fastening opened loading-doors and lifting wheels when fitting them. A suitable combination tool for such operations is lacking at present. Other fields in which such a combination tool would be desirable are for example joinery and carpentry, where it might for instance be used for the same purposes as fixtures and screw clamps.

The purpose of the invention in question is to create a combination tool that solves the problems mentioned. This purpose is fulfilled by the proposed combination tool, which has been given the characteristics specified in the patent requirements.

The invention will now be described in greater detail with reference to the enclosed drawings, of which: fig I shows in perspective a first model of the proposed combination tool fig 2 shows the same model of the tool as in fig I in perspective from another angle fig 3 shows the same model as in fig I from the side fig 4 shows a second model of the proposed combination tool from the side fig 5 shows in perspective how the proposed combination tool can be used in the handling of goods vehicles, and fig 6 shows how the proposed combination tool can be used in joinery.

The combination tool shown in figs I and 2 in the invention's first form consists of a long component 11, in this case in the form of a hollow rail and a first 12 and

second 13 fastening arm. Both fastening arms 12 and 13 project more or less at a right angle to component 11 and in the same direction for fastening around the same ob ect or different objects. The first fastening arm is movable along the length of component 11 and is therefore attached to a holding bracket 14 which can be moved along component 11. In order to be able to lock holding bracket 14 and therefore fastening arm 12 in different positions along component 11 the bracket 14 is provided with a lock 15. The lock 15 consists of an eccentric lock with an eccentric disc 16, which is mounted in bearings on holding bracket 14 by means of an axle 14a which is detached to 14. Also mounted on axle 14a is a roughly U-shaped clamp 28. The legs of clamp 28 are each provided with an elongated hole 28a which permits the clamp to be moved towards or away from component 11. The part of clamp 28 which connects the two legs consists of a plate 28b situated between the eccentric disc 16 and component 11, and which is pressed fast between it and eccentric disc 16 when locked. Lock 15 is manipulated by means of a lever 17 attached to eccentric disc 16. As shown in fig 3 the eccentric lock is in open position with lever 17 up and in closed position with lever 17 down. The two-directional arrow in fig 3 indicates the directions in which the first fastening arm 12 can be shifted.

At the opposite end of component 11 from fastener 13 a winding device 18 for straps or cables is arranged, consisting of a crank 1 9 with attached hub 20 for winding up, for example, a strap. The other end of component 11 beyond the other fastening arm 13 is in the form of a crow-bar 21. This end of component 11 is equipped with a prop 22. This prop 22 can be inserted into component 11, which has the form of a hollow rail, as far as a stop 23. Fig 4 shows a second model of the proposed combination tool. It differs from the first model in that the second fastening arm 13 as well as the first fastening arm 12 is made movable along the length of component 11. For this purpose the second fastening arm 13 has been mounted on a

holding bracket 24 which may be shifted along component 11. In this holding bracket 24 two rods 25 and 26 are mounted, placed on either side of component 11 and at different positions along its length. When the second fastening arm 13 is under pressure, pushing it away from the first fastening arm 12, force is exerted on the first rod 25. As a result of this frictional resistance occurs between component 11 and the other rod 26, a frictional resistance that increases in proportion to the force exerted. Inside holding bracket 24 a plate spring 27 is fixed, working between component 11 and the upper part of holding bracket 24. By this means an initial moment is created even before the second fastening arm 13 is put under pressure, so that fastening arm 13 is held in place on component 11 when the tool is not fastened to anything, but is still easily shifted along the length of component 11.

Fig 5 shows various uses for the proposed combination tool. Thus 1 shows the use of the tool as a crow-bar for releasing trailer couplings. In 2 the tool is used as a prop for the tow bar of a trailer, for instance when iced over. In 3 the tool is shown in use as a prop for a wheel nut spanner when a wheel is removed. In 4 the tool is shown in use for unwinding straps. In 5 the crow-bar is shown being used to lift "hanging doors" and as an ice- scraper for the edge of a lorry platform. In 6 the tool is shown in use as a lever for tightening straps. In 7the tool is shown in use as a brace to hold opened doors together. Finally in 8 the tool is shown used as a lifting implement when wheels are mounted.

Fig 6 shows the use of the combination tool in joinery or carpentry as a screw clamp. In fact the uses to which the proposed combination tool can be put are infinitely variable and of course not restricted to those shown here.
