At least two supporting members, secured on the roof, have clamp strap mountings which are arranged detachably to hold at least two clamp straps which are parallel to the supporting members and coact with each other (to clamp a ski or other object) in such manner that should one strap fail to function properly the companion strap acts as a reserve.

11 Claims, 6 Drawing Figures SKI-HOLDING DEVICE WITH MDUNTINGS FOR CLAMP STRAPS This invention relates to a ski-holding device with mountings for clamp straps arranged in parallel with the longitudinal direction of the ski-holding device. Said device comprises at least two supporting tubes to be fastened on a motor car roof, which are provided with said clamp strap mountings and intended for objects, such as skis, water-skis, fishing-rods or the like to be clamped on the supporting tubes by the straps.

Ski-holding devices of the aforesaid kind heretofore were arranged usually for placing, for example, two pairs of .skis to the side of each other on the-supporting tubes, by providing on one side of each supporting tube a single clamp strap for one pair of skis and a single clamp strap for the second pair of skis.

Said clamp straps, however, are easily damaged such, that they break or loosen. When a clamp strap does not work any longer, the corresponding pair of skis will be detached from the ski-holding device and constitute a substantial traffic risk. A further disadvantage of known ski-holding devices of this kind is the fixedattachment of the clamp strap mountings on the supporting tubes, which does not permit adjustment of the distance between the clamp strap mountings to skis of varying widths, ski-sticks or the like.

These disadvantages are eliminated by a ski-holding device of the aforesaid kind, which is constructed according to the present invention and characterized in, that the clamp strap mountings are arranged such as to hold in an easily detachable way at least two clamp straps, which are in parallel with the respectivesupporting tube and coact with each other for clamping an object, in such a manner, that in the event of faulty function of one strap the other-strap acts as a reserve, and that the clamp strap mountings preferably are arranged for fastening the coacting clamp straps each on one side of the supporting tube. The clamp strap mountings have downwardly open recesses, which in a manner known per se are adapted for detachably fastening the straps therein. The clamp-strap mountings include preferably circular through holes, so that they can be threaded onto the supporting tubes and manually moved thereon, and the circumference of said through holes advantageously is provided with an axial guide slot, which embraces a longitudinal strip on the surface of the supporting tube. The clamp strap mountings advantageously are so arranged that the centre lines of the supporting tube and clamp straps are located substantially in the same horizontal plane.

At least two of the clamp strap mountings may advantageously, by stop means or the like, be adapted to be so fixed on the supporting tubes that they cannot be moved in the direction toward each other, and between said clamp strap mountings may be provided at least one manually movable clamp strap mounting, thereby rendering it possible to move the spacing between the last mentioned clamp strap mounting and some of the other mountings, for example, when a narrow object, such as a fishing-rod, or a wide object, such as a waterski, is to be clamped.

The clamp straps advantageously are elastomer straps with preferably round cross-section and provided at the ends in known manner with stop knobs, but they may, of course, also be designed in a different way. In order to obtain a suitable stretching of the clamp strap independently of the distance of the clamp strap mountings relative one another, the straps advantageously are provided, besides at its ends, with a plural.- ity of stop knobs along their length.

The invention is described in the following in greater detail with reference to the enclosed drawings, which show by way of example some embodiments of the invention.

FIG. 1 shows the ski-holding device in a lateral view.

FIG. 2 shows the ski-holding device seen from above.

FIG. 3 shows by a front view and on a larger scale a clamp strap mounting according to the invention, adapted for two coacting clamp straps located each on one side of a supporting tube with round cross-section.

- FIG. 4 shows a clamp strap mounting similar to that shown in FIG. 3, showing a mounting intended for the ends or the like of the supporting tube.

FIG. 5 shows by a front view a clamp strap mounting according to the invention, adapted for at least two coacting clamp straps located on the same side of a supporting tube with square cross-section. FIG. 6 shows a clamp strap mounting similar to that shown in FIG. 3, adapted for a supporting tube with, square cross-section.

In FIGS. l-4 a ski-holding device according to the invention is shown which comprises two supporting tubes, of which one tube 1v is shown in FIGS. 1 and 2. The supporting tube 1 has round cross-section and is provided at the ends with feet 2, which consist substantially of pipes projecting in a telescopic way into the supporting tube and are adapted to be fastened on a motor car roof in a known unspecified manner. Onto said supporting tube l'are threaded a plurality of clamp strap mountings 6 manually movable thereon, and onto. both ends of the tube are threaded clamp strap mountings 8 provided with fastening screws 7 for securing the mountings onthe supporting tube by screwing. The mountings 8 have an internal projection 9, which is intended for stopping against the end surface of the supporting tube and which is provided with a through hole, through which the tubular portions of the feet 2 are inserted.

The clamp strap mountings 6 comprise a manually movable annular portion 10, which is threaded onto the supporting tube and provided with two lugs 11 projecting each on one side of the clamp strap mounting. Said lugs 11 are provided with downwardly open recesses 12, which slightly taper downwards and each of which is adapted in a known manner for easily detachablyfasten therein a clamp strap 13. Each clamp strap =13consists of an elastorner, for example rubber, with round cross-section and is provided with a number. of stop knobs 14, which cannot pass through the recesses .11. The clamp straps 13, besides, have at one end a similar knob 15 intended as a finger grip.

The clamp strap mountings 6, as appears from FIGS. 1 and 2, are threaded onto the supporting tube 1, on the ends of which the clamp strap mountings 8 are secured by screws 7.

In FIGS. 1 and 2 two pairs of

skis

17, 17 and a pair of ski-sticks 18 are indicated, all of which are clamped on the supporting tubes 1 by means of the clamp straps l3 coacting in pairs relative each other. Only one of the tubes is shown in the Figure. The clamp straps are located above the skis, which, however, is shown only in FIG. 1.

The clamp strap mountings 6 are manually movable on the supporting tube 1 and thereby render it possible so to adjust the spacings between the clamp strap mountings that they are smaller or greater, so that the clamp straps can better hold, for example, skis, a fishing-rod, a water-ski or the like on the ski-holding device.

In the embodiment shown in FIG. 3, the through holes 20 of the clamp strap mountings are provided at their circumference with a guide slot 21 adapted so to embrace a longitudinal strap 22 on the surface on the supporting tube, that the clamp strap mounting cannot be rotated on the supporting tube (the strip 22 is only indicated in FIG. 3).

In FIG. 5 a clamp strap mounting 17 is shown in a modified embodiment of the invention. The mounting 17 is intended to be secured on a supporting tube'with square cross-section and provided with only one laterally projecting lug 11 arranged for two clamp straps 13 coacting relative each other and fastened on the same side of the supporting tube.

In another embodiment of the invention the supporting tube 1 may be arranged, for example, in a telescopic way in the center, and the ends of the supporting tube be elevated such as to form the feet 2 of the supporting tube, in which case the supportingtube and feet, thus, are manufactured integral.

Also other embodiments of the invention described above can be imagined within its scope.
