SKI LOCK Filed July 13, 1964 5 Sheets-Sheet 5 F/G l2 INVENTORS PAUL W POEHLMANN BY ROBERT a ANTON/0L! A T TORNE Y United States Patent Filed July 13, 1964, Ser. No. 382,277 Claims. (Cl. 70-58) This invention relates to a ski lock and, more particularly to a device for locking a pair of skis together in order to discourage the theft thereof.
With the expanding interest and participation in the sport of skiing, ski resorts are becoming more crowded and, as an unfortunate result, the weekend crowds attracted to the winter sport areas are less intimate and, to some extent, impersonal. With this change in complexion, there tends to be a diminished regard for personal property with an increase in the occurrences of theft. Since skis cannot conveniently be carried on the person or kept under surveillance at all times that they are not in use, they are particularly susceptible to theft,
It has long been customary to stand the skis in a snow bank or to lean them against a building while the skier is relaxing or occupied in other pursuits. With increasing frequency during recent years certain persons have taken advantage of the fact that skis were left unattended and have stolen skis for their own use or for resale. This is accomplished easily because the custom of depositing skis while relaxing is so widespread that an observer would not have reason to question the removal of a pair of skis and, of course, being at a ski resort there is no reason to suspect one carrying a pair of skis.
It is therefore, an object of our invention to provide a ski lock device designed to discourage the theft of skis.
It is a further object of our invention to provide a ski lock device that would render a person stealing skis conspicuous.
It is a further object of our invention to provide a device for locking skis together so that they cannot be used without destroying the lock, thereby deterring a would-be thief.
It is a further object of our invention to provide a ski lock device that is not awkward, cumbersome or inconvenient to handle while the skis are in use.
In carrying out this invention, we provide a ski lock device made up of a pair of interlocking elements each of which is secured directly to one of a pair of skis. When the interlocking elements are engaged, the skis can be separated only if first moved relative to each other in generally parallel planes. However, while they are so engaged, lock members on the elements are aligned and a padlock or a built-in lock is operated to lock the elements against such movement that would permit them to become disengaged. When the lock elements are engaged, the skis are preferably disposed in diverging or criss-cross relationship so that they are more difiicult to carry and, of course, unfit for use. Moreover, with the skis so disposed, a thief would appear conspicuous carrying them away, particularly when the function and purpose of our ski lock becomes widely known. Thus, the ski lock is a substantial deterrent to would-be thieves. A further deterrent resides in the fact that a thief has to destroy the lock before he can use the skis. Such destruction of the lock would be apparent and could render the skis themselves subject to question should he attempt to sell or use the skis himself.
Other objects and advantages of this invention will become apparent from the specification following when read in conjunction with the accompanying drawings wherein:

Referring now to the drawings more specifically, and particularly to FIGS. 1 to 5, we have shown a pair of skis 2 and 3 with ski poles 5, all of which are locked together by our ski lock device 6 hereinafter to be described. It will be noted that the skis 2 and 3 when so united are disposed in criss-cross relationship so that they ous should he attempt to transport them away.
In the embodiment of our invention shown in FIG. 2, the ski lock device 6 comprises a pair of elements 8 and 10 each of which is secured to the top flat surface of a ski 2 and 3 as by means of screws 12 and 14. The lock element 8 is formed with a planar bracket portion 16, in which are formed the holes 12a to accommodate the screws 12, and a channel-like receptacle portion 18 having an open end 19. At the trailing end of the bracket 16 is an upwardly extending lock panel 20 having a slot 22.
The other lock element 10 also includes a flat bracket portion 23 with screw holes 14a, but in addition is formed with a downwardly and rearwardly extending tongue 24 having an opening 25 therethrough which provides access to the screw 14. The tongue 24 is adapted to engage within the opening 19 in the receptacle 18 on the first lock element 8 so that the elements cannot be separated by moving them transversely relative to each other. Also, at the trailing end of the bracket 12 is an upright lock panel 26 having an enlarged slot 27.
Referring now to FIGS. 4 and 5, we have illustrated the manner in which the ski lock of FIG. 2 is operated. First the skis are arranged so that they oppose each other in criss-cross relationship though somewhat spaced as shown in FIG. 4. As so arranged, the brackets 8 and 10 are disposed generally parallel to each other with the rearward'ly extending tongue 24 spaced above and in front of the receptacle 18. Then, the skis are brought together so that the tongue 24 is inserted into the opening 19 of the receptacle 18. Then the ski 3 is moved rearward'ly with respect to ski 2 until the upwardly extending lock tabs 20 and 26 are adjacent each other with slots 22 and 27 in alignment. The alignment of the slots is facilitated by virtue of the fact that the slots are enlarged. When so disposed, a paddock 30 ('FIGS. 2 and 5) may be hooked through the straps 5a of the ski poles and around and through the aligned slots 22 and 27 of the lock panels 20 and 26. When the lock is then snapped shut, the ski straps and poles are locked in place and the ski lock elements 8 and 10 are held securely against relative lineal movement which is-requisite to their removal.
In FIG. 6 we have shown a similar form of ski lock comprising a pair of brackets 32 and 34, each including screw holes 36 for attachment thereof to each of a pair of skis. A downwardly and rearwandly extending tongue 38 is engageable in a complementary rece tacle 40 on the lower bracket 34 as in the first embodiment. However, in this particular form, an integral lock 42 is built into the lower bracket 34. The lock 42 may include a spring biased detent 44 which may be retracted and then engaged in a slot 46 in a lock panel on the upper bracket. A key hole 44:: permits operation of a suitable lock mechanism to hold the spring biased detent in its extended position.
In the embodiment of our invention shown in FIGS. 7 to 11 a pair of skis 5-2 and 53 are again secured in crisscross relationship by the ski lock 50. The eiements of this ski lock 54 and 56 again are provided with screw holes 58 for direct attachment to the skis and each includes an upwardly extending lock panel 60 and 61, respectively.
In this embodiment, each element 54 and 56 is provided with a central, raised portion 63 and 64 respectively. A pin 66 is secured to the elevated portion 63 of the element 54 to extend therefrom and on the top of the pin 66 is an enlarged head 68. In the elevated portion 64 of element 56 is formed a slot 70 slightly wider than the shank of the pin 66 and the slot 7 opens into an enlarged hole 72 which is large enough to receive the enlarged head 63 of the pin 66. On one of the elements 54 we provide an upstanding stop member 74 for a purpose hereinafter to be described.
The operation of this embodiment is illustrated in sequence in FIGS. 8 and 10. First the element 54 is engaged with the element 56 by bringing them together so that the enlarged head 68 of the pin 66 passes through the enlarged opening 72 whereby the lock elements are in the relationship shown in FIG. 9. Then, the lock elements 54 and 56 are moved relative to each other by sliding the pin 66 lineally along the slot 70 to the position shown in FIG. 10. Finally, the skis and hence the elements 54 and 56 are rotated relative to each other until the lock panel 61 of element 56 engages the stop member 74 on the element 54. In the position so determined by the stop 74, the desired criss-oross relationship of the skis is achieved and the lock-receiving slots 60a and 61a are in alignment.
It will be noted that the lock panel 61 of the element 56 is disposed inward of the lock panel 60 on the other element 54 so that relative lineal movement between the pin 66 and the slot 70 that is necessary to separate the elements is blocked. Thus, in order to release the ski look embodiment of FIGS. 7 to 11, it is first necessary to rotate the skis relative to each other through an arc sufiicient to move the lock panels 60 and 61 out of alignment with each other. Then, the pin 66 may be moved along the slot 70 to separate the elements 54 and 56.
As a final step, a suitable lock, such as the padlock 80 may be looped through the straps a of the ski poles 5 and then around the lock panel and through the aligned slots 60a, 61a, and then looked so that the elements 54 and 56 are secured against relative rotational movement which is necessary to separate them.
In FIGS. 12,13 and 14, we illustrate a form of lock wherein brackets 80 and 81, each with slots 83, are secured to the sides of skis 84 and 85, respectively, by means of screws or the like 82. It will be noted that the bracket 81 on the ski 85 is ofiset outward at 87 (FIG. 14) in order to accommodate the brackets 81 on the ski 84 between them. In operation of this embodiment, the skis 84 and 85 are arranged so that the brackets 80 and 81 are disposed side by side with slots 83' therein in alignment. Then a coupling tongue 90 having a stop head 92 is in: sorted through the aligned slots 83 to hold the skisto get-her. A series of holes 94'are provided in the intera looked tongue so that a suitable lock 96 may be inserted in the selected hole depending upon the widths of the skis. Preferably, as shown in FIGS. 12 and 13, the brackets and 81 on each ski are offset from each other lengthwise of the ski so that when the coupling tongue is inserted the skis will automatically assume the desired cri'ss-cross relationship.
In the embodiment of FIG. 15 a mounting plate 98 on one element 100 is provided with screw holes 98a and a pair of upwardly and oppositely extending tabs or ears 102 that are receivable in accommodating receptacles 104 in each of a pair of brackets 106 which are also provided with screw holes 106a. The receptacles 104 in the upper brackets are arranged in spaced relationship as shown so that the ears or tabs will fit between them. Thus, the receptacles may be inserted over the oppositely extending ears by positioning them, as shown, parallel to the sides of the tabs or ears 102. Then, the ski on which the brackets 106 are mounted may be rotated relative to the other ski until the oppositely extending tabs are received in the receptacles and the interlock panels on the complementary elements are in alignment. As in other embodiments, a lock may be inserted in the aligned slots 108a and 110a to prevent further rotation of the lock elements, thus securing them against rotation.
