Description:
A timber bunk assembly and a fastener of a timber bunk

Background of the invention

The invention relates to a timber bunk assembly which comprises a timber bunk and at least two fasteners. The invention additionally relates to a fas- tener of a timber bunk.

Brief description of the invention

The timber bunk assembly according to the invention enables the fasteners to be adjusted. Fastenings of different kinds are possible by using basic parts of the fastener and additional parts connected to the basic part.

The timber bunk comprises a horizontal beam and two substantially vertical posts that are located at opposite sides of the horizontal beam. The horizontal beam and the posts are usually of steel. At both ends of the horizontal beam there are pockets fixedly connected to the horizontal beam and fixed to the horizontal beam by welding, for example. The posts are fixed to the pockets by bolting, in other words, the fastening of the posts is detachable. The pockets and the post are so designed that when the bolts are being tightened, the joint surfaces guide the posts into the correct angle in relation to the horizontal beam.

The timber bunk is usually secured to its base by two fasteners. The bunk assembly may be mounted either fixedly or movably to a chassis of a truck or trailer by using the basic parts of the fastener and additional parts that are appropriate to each individual case. A basic part of the fastener comprises a clamping piece, fitting piece, top plate, lateral guard, and bottom plate. The basic parts may be individual parts or, case-specifically, some of the parts may be joined into one part.

The trailer fastener has a slide plastic and a raising plate as the additional parts, and the bottom plate comprises a rubber pad and slide strip.

The movable fastener for a truck has the basic part, only, that is a clamping piece, fitting piece, top plate, lateral guard, and bottom plate. The bottom plate comprises a rubber pad and a slide strip.

The fixed fastener for a truck has the basic part, only, that is a clamping piece, fitting piece, top plate, lateral guard, and bottom plate. The bottom plate comprises a rubber pad and, instead of a slide strip, two steel pieces.

The horizontal beam of the timber bunk has a bottom flange that has a toothing. The horizontal beam has a measuring scale in the standard location, which helps the adjusting of the frame width without a separate measurement. The bottom plate of the fastener has a hole pattern for attaching standardised sets of push rods.

By means of the toothing and the fitting part of the fasteners, the position of the fasteners may be adjusted for different frame widths. The frame width of the fasteners may thus be adjusted without welding or mechanical machining.

Detailed description of the invention

Figures la - lc and Figure 2 show a timber bunk that has a horizontal beam 1 and two vertical posts 2. The timber bunk is fixed to its base by fasteners 14. The detail A of Figure la is shown in Figure 6 in a 1:3 scale.

Figures 3a - 3c show a trailer fastener of the timber bunk. The trailer fastener comprises a clamping piece 3, fitting piece 4, top plate 5, slide plastic 6, raising plate 7, lateral guard 8, and bottom plate 9. The bottom plate 9 has a rub- ber pad 10 and a slide strip 11. When fastened to a carriage of a trailer, the timber bunk is attached with the fasteners of the carriage. The fastening of the timber bunk in this case takes place by means of a flange of the horizontal beam 1, clamping piece 3 and fitting piece 4. The flange of the horizontal beam 1 is straight in the middle of the horizontal beam 1, and the fitting piece 4 is installed with the straight side against the flange of the horizontal beam 1.

Figures 4a - 4c show a movable fastener of a timber bunk for a truck. The movable fastener of a truck comprises a clamping piece 3, fitting piece 4, top plate 5, lateral guard 8, and bottom plate 9. The bottom plate 9 has a rubber pad 10 and a slide strip 11.

Figures 5a - 5c show a fixed fastener of a timber bunk for a truck. The fixed fastener of a truck comprises a clamping piece 3, fitting piece 4, top plate 5, lateral guard 8, and bottom plate 9. In the fixed faster of a truck, the rubber pad 10 and slide strip 11 are replaced with steel pieces 12, 13.

Figure 6 shows a measuring scale 15 on the horizontal beam 1 of the timber bunk as seen from the side, and Figure 7 shows the toothing from above. The horizontal beam 1 has a toothing 16 and the fitting piece 4 has a toothing 17 compatible with the toothing on the horizontal beam, by means of which the location of the fastener 14 is determined.

A person skilled in the art will find it obvious that, as technology advances, the basic idea of the invention may be implemented in many different ways. The invention and its embodiments are thus not restricted to the above- described examples but may vary within the scope of the claims.
