Abstract
In one aspect, a leg activated brake for a foot supporting rolling device, such as a roller ski. Roller skis generally have one wheel mounted to each end of the foot supporting frame which houses a ski binding for the skier's boot. The brake system mounts to the frame of the roller ski and when the brake is activated by the leg, the brake applies frictional force to the rear wheel to stop the roller ski.
Description
- The present invention relates to roller skis. Roller skis are used by skiers in the non snow seasons, mainly for training by competitive cross country and Alpine skiers. Roller skis have a frame which supports the foot, generally with one wheel in front and one wheel in the back. Mounted to the frame is a ski binding for attaching the ski boot to the frame as shown in
FIG. 1 . Contemporary roller skis have wheels from about 65 to 150 mm in diameter and the foot supporting frames vary in length from about 450 to 700 mm. - Roller skis have been commercially available for over 35 years but, until the present invention, no one has offered a leg activated brake for conventional roller skis. Prior art includes hand activated brakes and using ski poles to stop the skis. Braking by a ski pole is unsafe and not effective. To brake with a hand activated brake is difficult without the skier loosing his balance and in an emergency the brake cannot be activated quickly enough as the skier has to reach, with his hand holding the ski pole, the brake pull handle which is generally attached to the skiers leg as depicted in
FIG. 12 . - In order for the skier to preserve balance the skier should have both hands on the ski poles and the body should be in a balanced ski position. For safety and rapid braking in an emergency situation, the brake should be able to be activated by the leg when the skier is in a stable position. This position is often referred to as the “Telemark” position and is shown in
FIG. 11 . In this position the braking leg acts a brace when slowing down preventing the skier from falling forward from the forces imposed on the body when braking. - U.S. Pat. No. 6,082,768 describes a leg activated brake for roller skis, where the brake is an integral part of the foot platform and the roller ski design. U.S. Pat. No. 4,033,596 describes a foot activated brake for roller skis with two, side by side, wheels in the back, but the patent does not provide a method for the brake to be adjusted for different wheels, ski bindings, ski boots, roller ski frames and different user's anatomy. Because U.S. Pat. No. 4,033,596 did not provide solutions for these variables, no commercial leg activated brakes were produced for conventional roller skis prior to the invention described herein.
- U.S. Pat. No. 5,924,704 describes another foot activated brake for roller skis but, as in U.S. Pat. No. 6,082,768, the brake is not suitable for mounting to conventional roller ski frames.
- The main object of the invention is to provide a braking system for conventional roller skis that can be leg activated only when the skier is in a stable position and a brake that does not touch any part of the users anatomy except when braking. The brake structure has members for vertical and horizontal adjustments so the brake structure can be adapted to a variety of boot designs, boot sizes, frame structures, ski binding mounting locations, wheel sizes and the user's anatomy.
- Another objective of the invention is to provide a method of mounting the brake to the foot supporting frame of conventional roller skis in such a manner that the frame retains its structural integrity and the brake structure does not interfere with the ski binding or the ski boot.
- The brake structure of the invention is such that it can be mounted to the roller ski frame with conventional screws and it utilizes minimal space. In one embodiment the brake can also be folded across the ski binding.
- Other advantages of the invention will be apparent from the following descriptions of the embodiments thereof and from the claims.

- Referring to
FIGS. 2, 3 , 4, and 5 the roller ski includes afoot frame support 1, to which is mounted a singlerear wheel 2 and a singlefront wheel 3. - Mounted to the frame is ski binding 16, to which is attached
ski boot 4. - The roller ski further includes a U shaped
bottom support member 17, which is fastened to theframe 1. Pivotally mounted tobottom support member 17, viapivot pin 8, is thelower member 6 to which is mounted the upper articulatedmember 7 viamounting screws 10. - Mounted to
member 7 is theyoke member 14 which is fastened by mountingscrews 13. Mounted to thelower member 6 isbrake pad 5. Mounted to U shapedsupport member 17 and tomember 6 isextension spring 15. - When the brake is in the upward position for braking as shown in
FIGS. 2, 3 , and 4, the brake is held in the upright position bypivot pin 8, spring loadedplunger 9 andextension spring 15 in such a manner that the brake can only be pivotally moved in the direction of the rear wheel. When the skier's leg pushes backward againstyoke 14, the joined structure pivots onpin 8, moving the brake pad against the wheel and stopping the roller ski. As the skier removes the leg pressure fromyoke 14, the spring tension returnsmember 6, of the connected structure, to a vertical position where it is stopped byplunger pin 9, the plunger being mounted to U shapedsupport 17 which fastened toframe 1. Withplunger pin 9 engaged the structure can only be pivoted toward the rear wheel. - For proper balance the binding 16, must be mounted in a specific position which is dependent on the boot size, the ski weight and the length of the ski.
-
FIG. 2 depicts the position ofmember 7 andyoke 14 when the skier has a large boot andframe 1 is fitted withsmall wheels -
FIG. 3 shows the position ofmember 7 andyoke 14 when the skier has a small boot andframe 1 haslarge wheels FIG. 4 shows the position ofyoke member 14 turned 180 degrees so it contacts the leg in a lower position, which is preferred by some users. -
FIG. 5 shows the brake withplunger pin 9 pulled out and the structure folded aboutpivot pin 8, soyoke member 14 rests on theplatform 1. - Referring to
FIGS. 6, 7 , 8, 9 and 10 these show more detailed views of one embodiment. In the embodiment shown joinedmembers Holes 23, serve no purpose except to make the structure lighter. U shapedmounting support 17 is shown attached toframe 1, viamounting screws 19. - Since ski bindings must be mounted to the top of the frame, all roller ski frames are designed to accept standard self tapping mounting screws.
- Mounted to the U shaped
support 17, via threadedpivot pin 8 andnut 22, islower member 6 which is held in the upright position by the tension ofextension spring 15 and by the spring loadedplunger 9, which contacts one side ofmember 6 and is fastened to U shapedsupport 17. - Attached to
member 6 isbrake pad 5 which can be moved to different vertical positions onmember 6 via screw holes 21 and 21 a which are vertically located, in pairs, onmember 6. In oneembodiment brake pad 5 has threaded holes to acceptscrews Brake pad 5 is constructed of heat treated steel with a minimum hardness of Rockwell 50C. - In the embodiment shown, spring loaded
plunger 9 is a standard commercially available unit which is fastened to the U shapedmember 17.Spring 15 is attached to U shapedmember 17 and tolower member 6 as shown inFIG. 6 . - In the design depicted,
member 7 is fastened tomember 6 by socket screws 10.Lower member 6 has clearance holes for thescrews 10, while theupper member 7 contains commercially available pressfit nuts 18, which accept the socket screws 10. -
Member 7 is angularly adjusted, with respect to tolower member 6, to fit the leg anatomy of different users. - When tightened, the clamping force generated by the socket screws 10 and
nuts 18, joinsmember 7 andmember 6 so they become an integral unit rotating aboutpivot pin 8. - In the embodiment depicted,
yoke assembly 14 is attached toupper member 7 bysocket screws 13 which are threaded intonuts 11 ofmember 7.Yoke 14 hasseveral holes 12, for greater adjustability of the yoke with respect to the users leg anatomy. In oneembodiment yoke assembly 14 is configured so it can contact the leg in a lower position by rotatingyoke 14 180 degrees and fastening the yoke tomember 7 as shown inFIG. 10 .
