[ 5 7 ABSTRACT An anti-theft device for skis comprises a U-shaped bolt that is received and releasably locked in place in boltreceiving openings disposed immediately adjacent the pointed forward end of each ski of a pair of skis. The bolt-receiving openings have a polygonal cross-section which-corresponds to the polygonal cross-section of the arms of the U-shaped bolt received in said openings. The axis of each bolt-receiving opening is disposed at an angle with respect to the longitudinal axis of the skis with which the opening is associated, the angle at which said bolt-receiving openings are disposed being such that the skis are rigidly fastened together with the upper surfaces of said skis facing each other and with the main body portion of said skis disposed at said angle with respect to each other when the arms of the U-shaped bolt are received in said bolt-receiving openings, thereby rendering the skis conspicuous and awkward to carry. The transverse portion of the U-shaped bolt may be formed with a pair of pole-receiving slots that receive the shafts of a pair of ski poles, thereby locking the poles to the skis.
5 Claims, 10 Drawing Figures ANTI-THEFT DEVICE FOR SKIS RELATED APPLICATION BACKGROUND OF THE INVENTION l. Field of the Invention This invention relates to anti-theft devices for skis and more particularly to a device which locks the skis in a distinctive V-shaped position that renders the skis conspicuous and awkward to carry.
.2. Prior Art When skis are not in use they are commonly strapped or otherwise fastened together with the relatively flat bottom surfaces in contact with each other. When fastened together in-this manner the skis are easy to carry about and are readily stored in racks or by thrusting the rearward ends of the skis vertically into a bank of snow outside a house or lodge. The owner of skis temporarily stored in this manner frequently leaves the skis unattended while engaging in other activities. Skis strapped together and stored unattended can easily be carried away by an unauthorized person or thief. That is to say,
7 a thief carrying off stolen skis strapped together in the usual manner is almost impossible to distinguish from the scores of other skiers in the area legitimately carrying their own skis strapped together in identical fashion. As a result, the theft of skis at ski resorts is a growing problem that is difficult to control because of the unobstrusive way in which a thief can purloin and carry off the stolen skis.
A number of devices have heretofore been proposed for preventing or frustrating the theft of skis at ski resorts and similar places. However, most of these prior art devices are cumbersome, or spoil the appearance and performance of the skis, or require special fittings at the ski rack, or have other disadvantages which make them impractical or unacceptable to the majority of skiers. After an intensive investigation of this problem l have now devised a novel anti-theft device for skis which is simple tome and which does not disfigure or harm the performance of the skis. Specifically, the antitheft device of the invention locks the two skis in a distinctive V-shaped position that makes the skis awkward' to carry and, especially, very conspicuous when carried off by an unauthorized person.
SUMMARY OF THE INVENTION The anti-theft device of my inventionis intended to be used in conjunction with a pair'of skis having relatively straight main body portions and upwardly curved forward end portions which terminate with blunt points. A bolt-receiving opening is disposed immediately adjacent the pointed forward end of each ski of said pair of skis, each bolt-receiving opening having a polygonal cross-section. A U-shaped bolt is provided the arms of which are adapted to be received in the bolt-receiving openings disposed at the forward ends of the skis, the arms of said U-shaped bolts having polygonal cross-sections that correspond to the polygonal cross-sections of the bolt-receiving openings. The boltreceiving openings are disposed at an angle with respect to the longitudinal axis of the ski with which each opening is associated, the angle at which said boltreceiving openings are disposed being'such that the skis are rigidly fastened together with the upper surfaces of the skis facing each other and with the main body portions of the skis disposed at an acute angle with respect to each other when the arms are received in said boltreceiving openings. In an advantageous modificationof the device the transverse portion of the U-shaped bolt between the two arms thereof is formed with a pair of pole receiving slots, each slot being adapted to receive the shaft of a ski pole adjacent the basket of the pole as hereinafter described. Finally, lock means are provided which are adapted to be releasably locked to the ends of the U-shaped bolt when the polygonal arms of the bolt are received in the polygonal openings of the skis. As a result, when the arms of the U-shaped bolt are received in the bolt receiving openings, the rela-v tively straight main body portions of the skis are rigidly maintained at an acute angle with respect to each other which renders the skis awkward to handle and very conspicuous to carry about.

' DESCRIPTION OF THE PREFERRED EMBODIMENTS pair of skis 10, each bolt-receiving opening being adapted to receive one ofthearms'of a .U-shaped bolt (for example, the bolt 15 in FIG. 1 As hereinafter 3 more fully described, the bolt-receiving openings and the arms of the U-shaped bolt received therein have matching polygonal cross-sections which prevent relative rotational movement of the bolt 15 and the skis 10 fastened together by the bolt. In addition, the axis of each bolt-receiving opening is disposed at an angle with respect to the longitudinal axis of the ski with which the opening is associated, the angle being such that the skis 10 are relatively rigidly fastened together with the upper surfaces of the skis facing each other and with the main body portions 11 of the skis 10 disposed at an acute angle (the angle in FIG. 1) with respect to each other when the arms of the bolt are received in the bolt receiving arms openings.
In the embodiment of the invention shown in FIGS. 1 to 3, the bolt-receiving openings 14 are formed in and extend through each ski of the pair of skis immediately adjacent the pointed forward ends 13 thereof. The axis of each bolt-receiving opening 14 lies in a plane that includes the longitudinal axis (hereinafter referred to as the plane of the longitudinal axis) of the ski in which the opening 14 is formed. Moreover, as previously noted the axis of each bolt-receiving opening 14 is disposed at an angle with respect to the longitudinal axis of the ski with which it is associated, this angle being equal to about one-half 6. The U-shaped bolt 15 is provided arms 16 of which are adapted to be received in the bolt-receiving openings 14 formed in the ends of the skis. As shown best in FIG. 3, the boltreceiving openings 14 and the arms 16 of the bolt 15 have matching polygonal cross-sections which prevent relative rotational movement of the bolt 15 and the skis 10 fastened together with the bolt. Lock means 17 are also provided which are adapted to be releasably locked to the ends of the arms 16 of the bolt 15 when the arms 16 are received in the bolt-receiving openings 14. The lock means 17 advantageously is of conventional padlock design which is unlocked by means of a removable key 18.
In the embodiment shown in FIGS. 4 to 6, the boltreceiving openings are formed in a bracket 20 which is secured by means of screws or the like to the upper surface of the curved forward end portion 12 of the skis 10 immediately adjacent the pointed forward ends 13 thereof. The brackets 20 are positioned so that the axis of each bolt-receiving opening 24 is disposed perpendicular to the plane of the longitudinal axis of the ski with which the opening 24 is associated. A bolt 25 is provided the arms 26 of which are adapted to be received in the bolt-receiving openings 24 of the brackets 20. As in the previously described embodiment, the bolt-receiving openings 24 and the arms 26 of the bolt 25 have matching polygonal cross-sections which prevent relative rotational movement of the bolt 25 and the skis 10 when the skis are fastened together by the bolt. Also as previously described, lock means 27 are provided which is adapted to be releasably locked to the ends of the arms 26 of the U-shaped bolt 25 when the bolt is received inthe openings 24, the removable key 28 being used to unlock the lock means 27.
When the arms of the bolt 15 are received in the boltreceiving openings 14 of the embodiment of FIGS. 1 to 3, and when the arms of the bolt 25 are received in the bolt-receiving openings 24 of the embodiment of FIGS. 4 to 6, the pair of skis 10 are rigidly'locked together with the upper surfaces of the skis facing each other and with the main body portions 11 disposed at an angle (the angle 0) with respect to each other. The rigidity with which the skis 10 are fastened together results from the matching polygonal cross-sections of the bolt-receiving openings (14 and 24) and the arms (16 and 26) of the bolt (15 and 25) received therein. The acute angle that the main body portions 11 are disposed with respect to each other results from the angle at which the-axis of each bolt-receiving opening lies with respect to the longitudinal axis of the skis with which the opening is associated. The resulting V- shaped configuration of the relatively flat main body portions 11 of the skis l0 renders the skis awkward to handle and very conspicuous when being carried off by an unauthorized person.
Most skiers use ski poles when skiing, and it is desirable to provide means for securing the ski poles to the skis with which the poles are associated when the skis and poles are left unattended by the skier. In the modification of the invention shown in FIGS. 7 to 10, the anti-theft device is provided with means for locking a pair of conventional ski poles to the skis. As shown best in FIGS. 7 and 8, a conventional ski pole comprises a ski pole shaft 30 having a ski pole basket 31 secured to the shaft adjacent the lower end or tip of the pole. The ski pole has a hand grip or handle at its upper end, the pole shaft 30 tapering gradually from a maximum diameter at the handle to a minimum diameter at the tip. When the shaft 30 of one ski pole is inserted through the basket 31 of the other ski pole and the shafts are held parallel as shown in FIGS. 7 and 8, the average distance between the shafts 30 is surprisingly uniform for the majority of ski poles now being manufactured. A pair of ski poles thus joined together are secured to the for-v ward end portions 12 of the skis 10 by means of a modified version of the U-shaped bolt of the anti-theft device as hereinafter described. I
As in the previously described embodiment, a bracket 33 having a bolt-receiving opening 34 formed therein is secured to the upper surface of the curved forward end portion 12 of each ski 10 adjacent the forward end 13 thereof. A U-shaped bolt 35 is provided the arms 36 of which are adapted to be received in the bolt-receiving openings 34 of the brackets 33. As before, the bolt-receiving openings 34 and the arms 36 of the bolt 35 have matching polygonal cross-sections which prevent relative rotational movement of the bolt 35 and the skis 10 when the skis are fastened together by the bolt. As also previously described, lock means 37 are provided which are adapted to be releasably locked to the ends of the arms 36 of the U-shaped bolt 35 when the bolt is received in the openings 34, the removable key 38 being used to unlock the lock means 37.
In the modified version of the anti-theft device the transverse portion 40 of the U-shaped bolt 35 that extends between the arms 36 of the boltis formed with a pair of pole-receiving slots 41. Each slot 41 is adapted to receive the shaft 30 of one of the pair of ski poles adjacent the basket 31. When the shaft 30 of each ski pole is received in one of the corresponding slots 41 of the bolt 35, and when the skis, ski poles and anti-theft device are assembled as shown in the drawings, the ski poles are firmly secured to the forward end portions 12 of the skis as clearly shown in FIGS. 7, 9 and 10. When thus assembled, the skis 10 are rigidly locked together at an'acute angle and the ski poles are securely fastened ing a relatively straight main body portion and an upwardly curved forward end portion which terminates with a blunt point, which comprises a bolt-receiving opening for each ski of said pair disposed immediately adjacent the pointed forward end of each ski at an angle with respect to the longitudinal axis of said ski, each bolt-receiving opening having a polygonal cross-section.
a U-shaped bolt the arms of which are adapted to be received in the bolt-receiving openings at the forward ends of the skis, said arms each having a polygonal cross section that corresponds to the polygonal cross-section of the bolt-receiving openings,
