DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] In the present detailed description, embodiments of a wheel-nut locking clamp according to the present invention are mainly discussed with reference to views showing a wheel-nut locking clamp with components and portions being relevant in relation to various embodiments of the invention. It should be noted that this by no means limits the scope of the invention, which is also applicable in other circumstances for instance with other types or variants of wheel-nut locking clamps than the embodiments shown in the appended drawings. Further, that specific features are mentioned in connection to an embodiment of the invention does not mean that those components cannot be used to an advantage together with other embodiments of the invention.

[0039] The invention will now by way of example be described in more detail by means of embodiments and with reference to the accompanying drawings.

[0040] FIG. 1 is a perspective view of a wheel-nut locking clamp 1 and a wheel 5. The wheel-nut locking clamp 1 is arranged to be fitted on the wheel-nuts 3 of the wheel 5. In FIG. 1, three pairs of wheel-nuts 3 have been locked by the fitting of wheel-nut locking clamps 1. It is of course possible to fit a wheel with any number of wheel-nut locking clamps deemed suitable, e.g. locking each wheel-nut 3 of the wheel 5. It should also be understood that a wheel-nut locking clamp 1 may be used to overlap another wheel-nut locking clamp such that two wheel-nut locking clamps lock a total of three nuts, or even double fit two wheel-nut locking clamps to two wheel-nuts.

[0041] FIG. 2A is a side view showing a longitudinal cross-section of the wheel-nut locking clamp 1 of FIG. 1. The wheel-nut locking clamp comprises a first portion 7 and a second portion 9, arranged at an angle to each other. The angle may be 180 such that the first and second portion 7, 9 are arranged in a flat manner, or the angle may be in the range of 120-180. Each of the first portion 7 and the second portion 9 has a wheel facing side 13 and an outer side 15, and is each provided with a through hole 17. The wheel-nut locking clamp 1 is adapted to clamp wheel-nuts having a diameter of 30-33 mm, therefore the through holes 17 have a diameter of at least 33 mm. The wheel facing side 13 and the outer side 15 are arranged opposite to each other. The wheel facing side 13 is the side of the first portion 7 and second portion 9 which is arranged to face the wheel 5 when the wheel-nut locking clamp 1 is fitted on the wheel-nuts 3 of a wheel 5. The through hole 17 is arranged so that a hole is provided going from the wheel facing side 13 to the outer side 15.

[0042] The wheel-nut locking clamp further comprises an intermediary portion 11, arranged between the first portion 7 and the second portion 9. In FIG. 2A, the intermediary portion 11 is U-shaped and the transition between the intermediary portion 11 and each of the first portion 7 and the second portion 9 is rounded. The shape of the intermediary portion 11 may also be triangular, square or straight. The transition between the intermediary portion 11 and each of the first portion 7 and the second portion 9 may also be sharp.

[0043] On the perimeter of their respective through holes 17, each of the first portion 7 and the second portion 9 is provided with a flange 19. The flanges 19 are arranged to extend from a perimeter of the through holes 17 towards a center axis 23 of the through holes 17. As seen in FIG. 2B, the flange 19 is arranged at an angle to the first portion 7 or the second portion 9. The angle is at least 30.

[0044] Furthermore, the flanges 19 are provided with a plurality of protruding elements 21 extending towards a center axis 23 of the through holes 17. The protruding elements are provided at an angle to the first portion 7 or the second portion 9. In FIG. 2B, the angle is larger than the angle and the angle is at least 15. Depending on the design of the wheel-nut 3 to be locked, other relationships between the angle and the angle are of course possible, e.g. the angle can be equal to the angle , or, the angle can be smaller than the angle .

[0045] FIG. 3 shows the wheel-nut locking clamp 1 from FIG. 2A after it has been fitted on a pair of wheel-nuts 3 of a wheel 5. As can be seen in the drawing, the wheel-nut locking clamp 1 is arranged so that the flanges 19 are substantially undeformed, or only deformed to a small amount, by the conically shaped bases 25 of the wheel-nuts 3.

[0046] In contrast, the protruding elements 21 are deformed by the wheel-nuts 3 upon fitting the wheel-nut locking clamp 1 to the wheel-nuts 3, thereby making the angle larger after fitting than it was before. This deformation of the protruding elements 21 is at least partially elastic. Thus, the protruding elements 21 are tensioned against the wheel-nuts 3 so that the wheel-nuts 3 are prevented from turning.

[0047] Furthermore, the wheel-nut locking clamp 1 is arranged so that the intermediary portion 11 is deformed upon fitting the wheel-nut locking clamp 1 to the wheel-nuts 3, thereby making the angle larger after fitting than it was before. This deformation of the intermediary portion 11 is at least partially elastic.

[0048] FIGS. 4-5 are perspective views of the wheel-nut locking clamp 1 and FIG. 6 is a top view of the wheel-nut locking clamp 1. The flanges 19 located at the perimeter of their respective through holes 17 and the protruding elements 21 may be more clearly seen in FIGS. 4-6.

[0049] In the figures described above, the first and second portions 7, 9 are symmetrical mirror images of each other. However, it is possible that the first and second portions 7, 9 have different designs, e.g. the through hole 17 could be provided in one location on the first portion 7 and in another location on the second portion 9, or, the length of the first portion 7 can be longer than the length of the second portion 9. The protruding elements 21 are throughout the drawings shown having a substantially isosceles trapezoidal shape with rounded corners. It is of course possible that the protruding elements have other shapes, such as rectangular, square, with or without rounded corners.

[0050] Further, in the appended drawings twelve protruding elements 21 are shown to be arranged on each flange 19 at the through holes 17. It is of course possible to use fewer or more protruding elements, such as any number in the range of 2 (two) to 20 (twenty) protruding elements (not shown). The protruding elements 21 are also shown as being equally distanced from the adjacent protruding elements, i.e. each protruding element 21 have the same pitch distance. This may be altered such that larger concentrations of protruding elements are placed on certain portions of the flange (not shown).

[0051] Although exemplary embodiments of the present invention have been described herein, it should be apparent to those having ordinary skill in the art that a number of changes, modifications or alterations to the invention as described herein may be made. Thus, the above description of the various embodiments of the present invention and the accompanying drawings are to be regarded as non-limiting examples of the invention and the scope of protection is defined by the appended claims.

[0052] Furthermore, any reference signs in the claims should not be construed as limiting the scope.
