Definitions
- Metal bars such as rock drill rods, are often shipped in lots comprising a large number of bars of equal size, which one wishes to keep bundled together for simpler handling. This is accomplished with shaped supports of wood or plastics, keeping the bars straight and parallel at such a distance that they do not touch each other.
- the present invention is a supporting clamp consisting of two parts, which can be adapted to four different bar diameter by positional changes between the parts, and which exerts an elastic pressure on the bars even with undersize diameters within the normal diameter tolerance limits.
- a supporting clamp according to the invention consists of two differently shaped parts: a base with upwardly pointing claws, and a reversible lid, which can be placed in four different positions by reversing about a horizontal and a vertical axis, corresponding to four different bar diameter.
- the claws are provided with gripping surfaces to hold the lid in its different positions.
- FIG. 1 The clamp is further described with reference to figure 1, showing a base, figure 2 showing a lid and figures 3 to 6 showing sections through the clamp with the lid in its four different positions, where a dot helps to illustrate the different lid positions in the figures.
- the base comprises two side plates (11,12) upwardly extending as a plurality of claws (13,14), where the claws (13) on one side plate (11) are shaped different from the claws (14) on the other side plate (12).
- the side plates (11,12) are recessed towards the middle and connected by transverse walls (17). Between the claws (13,14) on each side, the side plates are lowered and form supporting contours (18,19).
- the claws (13,14) are resilient and in their upper parts tapering. Each claw is joined to the side plate by two pillars (24). Below the tapering part each claw has gripping surfaces of different shape facing downwards. On each of the claws (13) of the first side plate (11) there is one upper gripping surface (21) with a width equal to the distance between the pillars (24) and a divided lower gripping surface (20) in two portions each covering the width of one pillar (24). On each of the claws (14) of the second side plate (12) there is one upper gripping surface (23) with a width equal to the full width of the claw (14) and a lower gripping surface (22) which only extends between the pillars (24). On the underside of the base there are two short tongues (25) below each claw (13,14).
- the lid comprises a central plate (31) with two raised longitudinal ribs (32,33) on each side.
- the plate (31) is, at least in regions adjoining the claws (13,14) of the base, narrow enough to fit between the claws, and is in this region provided at one edge with tongues (37) each with a width equal to the distance between the pillars (24), and at the other edge with shelves (36) with a width equal to the width of an entire claw (13,14).
- tongues (37) and shelves (36) are connected by transverse walls (38).
- the central part (39) of the rib is lower than the rest of the ribs (32,33) and chamfered or rounded.
- Figure 3 shows a cross-section of the clamp at a pair of claws (13,14) when the lid is in its lowest position to accomodate the smallest diameter bar.
- the lid is turned so that the tongue (37) and the shelf (36) are located higher than the central plate (31) of the lid, which is supposed to be symmetric with respect to those surfaces of the ribs (32,33) which will press against the bars.
- the tongue (37) rests against the lower gripping surface (22) between the pillars (24), and the shelf (36) rests against the divided lower gripping surface (20).
- Figure 4 shows a cross-section at a pair of claws (13,14) where the lid has been reversed about a vertical axis relative to figure 3, with the tongue (37) resting against the upper gripping surface (21) between the pillars (24), and the shelf (36) resting against the full width upper gripping surface (23), placing the lid in its second lowest position.
- Figure 5 shows a cross-section at a pair of claws (13,14) where the lid has been reversed about a horizontal axis relative to figure 4, causing the central plate (31) of the lid to be located higher than the tongue (37) and the shelf (36).
- the tongue (37) rests against the lower gripping surface (22) between the pillars (24), and the shelf (36) rests against the divided lower gripping surface (20), placing the lid in its second highest position.
- Figure 6 shows a cross-section at a pair of claws (13,14) where the lid has been reversed about a vertical axis relative to figure 5, with the tongue (37) resting against the upper gripping surface (21) between the pillars (24), and the shelf (36) resting against the upper full width gripping surface (23), placing the lid in its highest position, accomodating the largest diameter bar.
- the clamp is applied to the metal bars, which may have round or hexagonal section, by placing the bars on the supporting edges (18,19) of the side plates (11,12) of the base.
- the tongues (37) of the lid are then inserted below the gripping surface (21,22) between the pillars (24) of the claws (13,14) of that side plate which corresponds to the pertinent diameter, followed by pressing down that edge of the lid which carries the shelves (36) until the shelves (36) rest under the gripping surfaces of the claws of the other side plate.
- the invention has been described with application to round or hexagonal bars, but by suitably shaping the supporting edges (18,19) it can be adapted to any type of bar, or to two or more bars between neighbouring pairs of claws.
- the number of claws or bars in a layer is not restricted to what is shown in the figures.
- the clamps can also be used for bar-shaped items of other or composite materails, such as electric cables.
- Suitable material for the clamps is a synthetic resin with or without fiber reinforcement, since this ensures a suitable resilience of the pillars (24) of the claws.
- the described embodiment with gripping surfaces (20,21,22,23) in two levels and unsymmetric tongues (37) and shelves (36) has four different lid positions. It is within the scope of the invention to utilize only two positions by putting all gripping surfaces in one level, or by omitting one reversing possibility of the lid, or to utilize more than four positions by combining a choice of bases and lids..
