April 19, 1960 INVENTOR. MORTON STIMLER United States PatentOfiiice 2,33,324 Patented Apr. 1%, 1960 SKI LEASH Morton Stimler, Hyattsville, Md. Application December 23, 1957, Serial No. 704,436
6 Claims. (Cl. 280-1135) This invention relates to a mechanism for linking a ski to a skier by a leash whereby the ski is prevented from sliding down the slope away from the skier should it become disengaged from the boot as, for example, with the use of safety release binders, and moreover to provide this link between ski boot and ski in a manner which minimizes the danger of a released ski striking the skier during a high speed fall.
Heretofore the linking of a ski boot to a ski has been accomplished by a connecting strap attached at its ends to appropriate portions on the ski and boot respectively, and of sufficiently short length to prevent snagging, tangling or fouling while the skier is skiing.
There are several disadvantages to the old devices, one of which is the danger to a falling skier of being struck by his own ski which is released during a fall and is pulled closely behind him by the short connecting strap. Another disadvantage is that the short connecting strap often breaks under the stress to which it is subjected during a high speed fall causing the skier to lose his ski which, acted upon by the force of gravity, will then normally accelerate downhill, thereby creating an inconvenience to the skier, with the possibility of damage to the ski by collision, and a serious hazard to other skiers. These disadvantages are mutually complementary in the old devices in that interconnecting the boot and ski by means of a hightensile strength strap which is capable of withstanding the forces associated with high speed falls increases the danger to the falling skier of being struck by his released ski, and interconnecting the boot and ski by means of a low tensile strength strap designed to break during a high speed fall, in order to minimize this danger, results in a lost ski and its associated hazard and inconvenience to the skier.
The invention described and claimed herein possesses all of the advantages and none of the foregoing disadvantages of the prior art devices.
In accordance with the present invention this is achieved by providing a leash linking the ski boot to the ski and conveniently carrying a long-line stowed by a storage member in such a manner that the line is immediately released and pays out when a predetermined force is applied to it, such, for example, as would be applied when the ski boot and ski become separated during a fall of the skier, thereby permitting the ski to move sufficiently distant from the skier to minimize the danger of his being struck by his dislodged ski and providing a means whereby the skier may easily recover his ski, and restore the leash to its initial condition by rewinding the line on the storage member. A small portion of the leash is made of elastic material to absorb the shock which would ordinarily be experienced by the leash when its full length has been payed out, thereby preventing the escape of the ski by leash breakage. The operation of this device will become more clearly apparent from the following description.
One of the objects of this invention is to provide a new and improved ski leash having means for maintaining a flexible connection between a ski and the boot associated therewith when the ski has become disengaged from the boot during a skiing operation.
Another object is to provide a flexible connection between a ski and boot which is effective when the ski is moved a predetermined distance from skiing operation.
A further object is to provide a flexible connection between a ski and ski boot in which a length of line comprising the connection is withdrawn from an initial stowed condition to an extended condition when the ski is dislodged and moves away from the boot during a skiing operation, and which permits the movement of the ski from the ski boot to a limited predetermined distance suflicient to prevent the skier being struck by a dislodged ski as the line becomes taut.
A still further object of this invention is to provide a leash connection between a ski and boot which includes elastic means for reducing the shock to which the leash is subjected when it reaches the fully extended position which otherwise would cause breakage of the leash.
Another object is to provide a ski leash which may be detachably secured to a ski and ski boot in an initial stowed condition and which includes a flexible connection between the ski and the boot when the ski has become dislodged from the boot, whereby the dislodged ski may easily be retrieved by the skier to resume the skiing operation.
Still another object is to provide a new and improved ski leash, having the foregoing advantages, which is inexpensive to manufacture, simple and compact in construction, reliable in use and which may be easily and quickly attached and detached at will to a ski boot and ski the boot during a description taken in conjunction with the accompanying drawing of which:
Fig. 1 is an elevational view of a portion of a ski boot and ski connected by the device of the present invention according to a preferred embodiment thereof;
Fig. 2 is an enlarged elevational sectional view, partially broken away, of the device of the present invention;
Fig. 3 is a view, partially broken away, shown the ski leash of Fig. l in the process of paying out when the boot and ski have become separated and are moving away from each other; and
Fig. 4 is a view showing the leash in its storage position on the ski when not in use.
Referring now to the drawing for a more complete understanding of the invention, and more particularly to a toe binder 12 with the device of the present invention,
the flexible ski leash 15, connecting the boot and ski in:
the normal skiing condition. One end of the line 13 is: attached to the ski at a suitable portion thereof such, for example, as the looped portion of the bracket 14 by' means of connector 17, and one end of the elastic shock absorber 16, made of any material suitable for the purpose such, for example, as rubber or any of the synthetic varieties thereof, is connected to the boot in any suitable manner as by connector 18 at connecting ring 19 secured to the boot lace 21.
Fig. 2 is an enlarged elevational view showing a line stowage or dispensing spool or bobbin 22 through which a hole 23 preferably extends axially for the full length of the spool. One end of the elastic shock absorber 16 passes through the hole 23 and is prevented from slipping out by a knot 24 which is tied in the end portion of the elastic shock absorber, and which abuts against the re-' cessed portion 25 of the spool. The other end of the elastic shock absorber is secured to the connectorls for detachably connecting the leash to the boot. One end of the line 13 is secured to the knotted end of the elastic shock absorber and is shown wound on the spool in the on which is.
3 initial stowed condition with the other end of the line secured to' the connector 17 after passing through the hole 26 in the cover 27. An' intermediate portion of the line protruding through the hole 26 in .the cover is knotted on both sides of the hole at 28 and 29 respectively. The knot 28 inside the cover prevents the line from paying out until the cover and spool become separated; The knot 29 prevents that portion of the line which protrudes through the hole in the cover from being pulled into the cover when Winding the line on the spool and, co-acting with the knot 28, maintains a constant length of line protruding through the hole and extending outwardly from the-cover. The cover and spool are detachably fixed to one another in the initial stowed condition of the line,
a as shown in Fig. 2, by the gripping action of the plurality of curved spring fingers 32 formed by the plurality of slots 33 in the open end portion of the cover which is so shaped as to co-act with a a concave groove 31 in the end of the spool thereby forming a friction grip or releasable latch arrangement which holds the cover and spool in the position shown until a predetermined force is appliedto the cover and spool, through thetline and shock absrober, of suificient strength to cause separation thereof.
Fig. 3 is a view in which is shown the ski dislodgedfrom the boot 19. The sudden increase in tension in the line 13- caused by this dislodgement is transmitted to the cover at the knot 28, Fig. 2.
Fig. -4 is a view in which is shown a convenient storage position of the leash 15 on the ski 11 when not in use. The connector 18' is shown connected to the ski at the bracket 14.
In a skiing operation utilizing the device of the present invention, the ski leash would normally be used to form a flexible connection between each ski and its associated boot. The skis are first attached to the boots in the normal manner by means of the ski bindings 12 shown in Figs. 1 and 5. Assuming that each leash was initially in. the stored position shown in Fig. 4, the connector 18 must be disconnected from the bracket 14 and attached to the ring 19 in order to effect the skiing position shown in'Fig. 1. In the event of the dislodgement of a ski during askiing operation in which the ski and boot move apart with sufficient force to separate the cover 27 from thebobbin '22 as shown in Fig. 3, the line 13 will pay out permitting the ski and boot to continue to separate untilthe full length of line has payed ofr thebobbin. The shock to which the line would normally be subjected when its full length has been payed off the bobbin is greatly reduced by the elastic shock absorber 16 which thereby minimizes leash breakage. Thus a positive connection between ski and skiboot is maintained and the ski is permitted to rnovea safe distance away from the skier. The ski may then be retrieved by means of the leash and may againbe attached to the boot by rewinding the line on the bobbin and pressing the bobbin into the cover so that the spring fingers engage the, groove in the bobbin and the skier may then continue his skiing operation.
Whereas the invention has been described with reference to a particular example which gives satisfactory results, it is not so limited as various changes and modifications'may' be made by one skilled in the art to which this invention pertains, after understanding the invention, without departing from the spirit and scope of the invention, and it is my intention therefore, in the appended claims, to cover all such changesand modifications.
