Abstract
Abstract An adjusting device for adjusting the position of weights mounted for longitudinal movement within a ski. A drum is rotatably supported within a housing on the ski and has flat belts wound thereon, one belt extending to a weight supported for movement between the binding area on the ski and the tail of the ski and the other belt extending to a weight mounted for movement between the tip of the ski and the binding area. A manually engageable setting member is provided for rotating the drum to control the amount of flat belt wound onto the drum. A hollow member is provided in the ski to simplify the manufacturing process. The hollow member has the flat belts and the weights mounted therein for movement with respect thereto along the longitudinal axis of the ski. Printed indicia can be provided on either the flat belts or on the ski to indicate the relative location of the weights with respect to the tip and the tail of the ski.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
125 words
In an adjusting mechanism for a ski, with which one or several mass members are movable within the ski member along its longitudinal axis and can be secured within the adjusting range at any desired point, with a set wheel which can be adjusted manually and with belts which are connected to the mass members and which are moved by the set wheel, the improvement comprising wherein the belts are flat belts which are stressed for pull and compression, the free ends of which flat belts are connected to each one of the mass members, and wherein at least one first drum is connected to the set wheel, onto the circumference and from the circumference of which the flat belts can be wound and unwound.
Claim 2
Dependent Claim
125 words
In an adjusting mechanism for a ski, with which one or several mass members are movable within the ski member along its longitudinal axis and can be secured within the adjusting range at any desired point, with a set wheel which can be adjusted manually and with belts which are connected to the mass members and which are moved by the set wheel, the improvement comprising wherein the belts are flat belts which are stressed for pull and compression, the free ends of which flat belts are connected to each one of the mass members, and wherein at least one first drum is connected to the set wheel, onto the circumference and from the circumference of which the flat belts can be wound and unwound.
Claim 3
Dependent Claim
35 words
The improved mechanism according to claim 1, wherein two first drums are provided, onto the circumference of which or from the circumference of which each one of the flat belts can be wound and unwound.
Claim 4
Dependent Claim
30 words
The improved mechanism according to claim 2, wherein a separate set wheel is connected to each one of the first drums for the individual adjustment of the associated mass member.
Claim 5
Dependent Claim
24 words
The improved mechanism according to claim 1, wherein both flat belts can be wound and unwound superposed onto or from only one first drum.
Claim 6
Dependent Claim
53 words
The improved mechanism according to claim 1, wherein four flat belts and four mass members are provided, and wherein each two of the flat belts can be wound and unwound superposed on or from the two first drums, in order to move each two of the four mass members parallel to one another.
Claim 7
Dependent Claim
63 words
The improved mechanism according to claim 1, wherein next to the first drum there is arranged a second drum, onto or from the circumference a third flat belt can be wound and unwound, wherein the first flat belts can be wound and unwound overlappingly together with same onto the first drum, and both drums are coupled with one another for their common rotation.
Claim 8
Dependent Claim
25 words
The improved mechanism according to claim 6, wherein each one gear is provided on the shafts of the drums, which gears mate with one another.
Claim 9
Dependent Claim
28 words
The improved mechanism according to claim 7, wherein between the gears a transmission ratio is selected, which reduces the controlling forces which are produced by the set wheel.
Claim 10
Dependent Claim
64 words
The improved mechanism according to claim 8, wherein the diameters of the drums are different and are adjusted to the transmission ratio of the gears in order to wind or unwind onto or from the first drum approximately the same length of the third flat belt, as is being wound or unwound onto or from the second drum, whereby, however, a certain clearance exists.
Claim 11
Dependent Claim
44 words
The improved mechanism according to claim 9, wherein the clearance is balanced by a spiral spring, which initially tensions one of the drums with respect to its associated gear, which permits a rotation with respect to the drum, which rotation corresponds with the clearance.
Claim 12
Dependent Claim
25 words
The improved mechanism according to claim 7, wherein the drums and gears are arranged in a housing, which is sealingly mounted on the ski member.
Claim 13
Dependent Claim
27 words
The improved mechanism according to claim 11, wherein guide pieces are provided for the bent-free feeding of the flat belts from the housing into the hollow member.
Claim 14
Dependent Claim
20 words
The improved mechanism according to claim 6, wherein the set wheel is positioned on the shaft of the second drum.
Claim 15
Dependent Claim
20 words
The improved mechanism according to claim 6, wherein the first and second drums are arranged axially parallel to one another.
Claim 16
Dependent Claim
62 words
The improved mechanism according to claim 6, wherein the first and second drums are arranged with axes which are positioned perpendicularly with respect to one another, wherein the drums are coupled through a bevel toothing or a worm drive and wherein at least one guide roller is provided for guiding the third flat belt from the second drum to the first drum.
Claim 17
Dependent Claim
26 words
The improved mechanism according to claim 10, including a clearance balancing spring which holds the guide roller in a position which tensions the third flat belt.
Claim 18
Dependent Claim
25 words
The improved mechanism according to claim 6, wherein the third flat belt is provided with a graduated indicia, which can be read through a window.
Claim 19
Dependent Claim
15 words
The improved mechanism according to claim 1, wherein the flat belts are manufactured of steel.
Claim 20
Dependent Claim
17 words
The improved mechanism according to claim 1, wherein the flat belts are slightly arced in transverse direction.
Claim 21
Dependent Claim
38 words
The improved mechanism according to claim 1, wherein the flat belts are guided in a flat hollow member, which extends along the longitudinal axis of the ski, in which hollow member the mass members are also movably guided.
Claim 22
Dependent Claim
24 words
The improved mechanism according to claim 15, wherein the hollow member is divided by at least one crossbar which extends in its longitudinal direction.
Claim 23
Dependent Claim
51 words
The improved mechanism according to claim 15, wherein the inside of the hollow member is accessible at the rear edge of the ski for installation and service and wherein a cap piece can be screwed to the rear edge of the ski for the moistureproof closing off of the hollow member.
Claim 24
Dependent Claim
71 words
The improved mechanism according to claim 22, wherein the hollow member is manufactured separately of a fiber-reinforced plastic and is subjected during the manufacture of the ski member, already inserted in same, together with same to individual manufacturing steps, as for example to the hardening, and a core piece is provided in the hollow member, which can be removed through the opening at the rear edge of the ski from same.
