Abstract: A ski brake mounted on a ski and retained normally in a retracted position. When the skier's boot becomes separated from the binding on the ski in a casual manner, such as during ascent on a chairlift, a strap joining the skier's boot and the ski brake permits the ski to remain connected to the skier, although in a dangling condition. However, should the skier's boot become separated from the binding in an abrupt manner, as when skiing, the strap releases a retention mechanism holding the brake in a first or retracted position. Thereupon, the strap is completely separated from the brake and the brake is rapidly moved by a spring into a second position such that a brake shoe extends below a lower surface of the ski for engaging ice, snow, and the like. The brake shoe has a roughened outer surface as a further aid in impeding advancement of the runaway ski. Whenever convenient to the skier, a release mechanism on the strap can be operated to disconnect the strap from the boot.

Abstract: A ski brake for automatic release upon lifiting of a ski boot from the surface of a ski so as to prevent free flight thereof comprises a spring-loaded brake element adapted to reach downwardly below the bottom surface of the ski. A bent wire forms a bight which can be engaged by the ski boot and carries the brake element. A tread plate is disposed on the bight and is connected by another element, e.g. another bent wire, to the mounting structure for the ski brake.

Abstract: The invention concerns braking devices for skis that will ensure their immobilization when unexpectedly separated from the ski boot.For a ski which is put on by positioning the boot at an angle and then pivoting it to lock it in place, the ski brake includes a braking element 17 mounted on a pin 17 whose extremity 21 is pushed back by the boot during pivoting so that the braking element is raised counter to the action of a spring.This arrangement facilitates placing the boot on the ski at an angle.

Abstract: A ski safety binding has a mechanism for deploying a ski brake as soon as the ski boot has left the binding.Various arrangements of the binding utilize mechanisms to deploy the ski brake which are responsive to both upward movement of the sole clamp following release of the binding, and to downward movement of the sole clamp following the boot pulling out from under the binding.

Abstract: Ski brake comprising a bail rotatably mounted about a fixed transverse axis on a ski having two brake arms extending alongside the ski on one side of the axis and a pedal on the other side of the axis, a flexural spring fastened to the pedal which extends to a supporting surface on top of the ski in all rotational positions of the bail. The spring is resiliently biased relative to the pedal such that in the absence of a ski boot on the pedal the spring rotates the bail into a braking position wherein the brake arms project below the ski. When a ski boot is placed on the pedal the bail is rotated against the bias of the spring into an inactive position wherein the brake arms are located in the plane of or above the ski. A roller can be provided at the end of the spring to roll on the supporting surface and/or the supporting surface can be provided with friction reducing properties.

Abstract: A ski brake having a resilient tensioning member to which is secured bladed members is mounted on a ski plate having a releasable binding thereon. The resilient member is normally held in a position parallel to the upper surface of the sole plate by the weight of the skier to hold the bladed members in a retracted position. A release of the ski boot from the sole plate will cause the spring force of the resilient tensioning member to effect a movement of the bladed members to an extended position to brake the ski.

Abstract: Disclosed is a ski brake of the type fixed to the upper surface of a ski. The brake includes a pair of brake shoes on opposite sides of the ski biased into a downward, active braking position, and a counter biasing pedal which holds the brake in an inactive position when held down by a ski boot. The pedal is a U-shaped loop formed by a pair of arms of unequal length and with separate pivot points longitudinally displaced on the ski, so that elastic deformation of the loop when it is pivoted gives rise to a return bias into the braking position. At the U connection between the arms there is provided an adjusting member in the form of a turnbuckle which permits the spacing between the arms to be adjusted to suit the particular width of the ski.

Abstract: A ski brake comprises plow means pivotally mounted to the trailing end of each of a pair of skis and hydraulic operator means to move said plow means downwardly and under the trailing ends of the skis to plow snow on which the skis are operating upwardly behind the skis. The hydraulic operator means is assembled to a ski pole carried by the skier, hydraulic forces developed by the operator means being transmitted through a harness attached to the skier's waist.

Abstract: The invention proposes a braking device for a ski, particularly for braking a ski which has become detached from a ski boot and continues to run on, on its own, said device having a double-armed brake stirrup, whose arms can be tilted about an axis which runs at right angles to the longitudinal direction of the ski and which extend in the inoperative position along opposite sides of the ski, the arms being tilted into the braking position by the action of a spring, in which position the ends of the arms on one side of the axis project downwardly into the surface over which the ski is running and the ends of the arms on the other side of the axis, which are joined together and are intended to be pressed down by the ski boot, are tilted upwardly after separation of the ski boot from the ski. The spring for tilting the stirrup is tensioned between said connected ends of said arms and a mounting plate, defining a line of action extending substantially through said axis in said inoperative position.

Abstract: A safety ski binding which includes a cable interconnecting a ski boot or plate attached to a ski boot with the ski. A restoring spring is provided which forces the cable toward a position holding the ski boot in an in-use skiing position on the ski, while permitting relative movement of the boot and ski and consequent extension of the cable. To prevent serious injuries in the case of full extension of the cable, the cable is disconnected, thereby fully separating the ski and boot. In preferred embodiments, a ski brake is provided to brake the separated ski.

Abstract: A ski brake comprises a wire pivoted on the support plate of a safety ski binding and displaceable from a rest position extending parallel to the ski to a braking position extending transverse thereto when one of the clamps of the ski binding disconnected from the skiboot and slides on the ski. To this end a guide may be mounted on the clamp and a formation on the brake element is engaged in this guide so as to automatically displace the brake element into the braking position when the skiboot is released. It is also possible to form two braking elements of a single springy wire extending through one of the clamps of the ski binding and otherwise pivoted on the support plate of the ski binding for automatic displacement of the ski brake into the braking position when a boot is released.

Abstract: Ski brake comprising a pair of braking members adapted to be disposed on either side of the ski, a transverse pivot pin extending across the ski and about which said members are adapted to pivot, and a control pedal adapted to be actuated either by the ski boot or by a ski-binding plate supporting said ski boot. Said control pedal consists of a rigid metal wire shaped to a bow configuration and rigid with said pair of braking members, and the ski brake also comprises a return spring consisting of a loop of resilient metal wire having one end attached to said control pedal and bearing with the opposite end upon the ski at a point spaced longitudinally in relation to said braking member pivot pin, the dimensions of said resilient wire loop being such that in its normal shape said resilient wire normally urges said control pedal to its raised position above the ski and said braking members to a position in which they project downwardly from the lower surface of the ski.

Abstract: A ski is provided with a heel clamp longitudinally slidable along the ski between a rear and a forward position and also pivotal on the ski between an up and a down position. A brake element is pivotal on the ski between a ready position extending parallel to the ski and a braking position extending generally normal thereto. A spring is provided for urging the brake element into the braking position. When a skiboot is securely held by the clamp it is in the down and rear position. When the boot is released and the clamp slides forwardly into the front position the abutments disengage to allow the brake element to assume the braking position. Similarly when the clamp pivots up into the upper position the brake element can assume the braking position. Pivoting of the clamp from the up to the down position automatically pushes the brake element back into the ready position.

Abstract: A snow ski brake becomes effective to stop a ski, after a skier falls and his or her boot is released and cleared from a ski binding, otherwise unintentionally starting a ski on a free runaway downhill run. The free run of the ski however, doesn't occur, because a plow like braking arm, originally held upright over the ski and at a right angle to the ski top, adjacent the ski boot heel plate, under spring force, immediately pivots through 180.degree. in a transverse plane about a horizontal axis, thereby projecting downwardly at a right angle to the ski bottom and becoming an excellent snow plow to stop the ski within a reasonably short distance. In one embodiment, the plow like braking arm is first held in its inactive position by having its transverse or lateral latching bar, which is secured to it at ninety degrees, held transversely adjacent the ski top by a spring biased catch.

Abstract: A safety ski binding or a ski brake is mounted on a ski and includes an operating lever pivotally mounted on the ski and actuated by the sole of the boot when the boot is fitted to the ski. The operating lever is provided at its free end with a pedal having substantially flat elongated opposite surfaces and an elongated non-circular cross-section movable by contact with the boot into a position where the elongated direction of the pedal is parallel to the lower surface of a boot mounted on said ski.

Abstract: An improved ski brake having a pair of blade members which extend laterally with respect to the ski and are pivotally supported against spring force about an axis which extends transversely with respect to the longitudinal axis of the ski. The two blade members are connected through a stepping plate and are held in the downnhill retracted position above the sliding surface of the ski by the force of the ski boot pressing downwardly thereon. The ski brake is composed of a section of spring steel wire having two portions thereof bent at 180.degree. to form the blade members. The ends of the spring steel wire are received in flanges on a base plate secured to the ski, which flanges have control cam surfaces thereon and which terminate in a locking recess. The ski brake is held in the braking position when the end portions of the spring steel wire are located in the locking recess.

Abstract: A structure for a use in either an anti-crossing device for skis or a ski brake. A torsion spring is utilized to urge a projection member to an upright position on the ski. In the anti-crossing device for skis, the resilient projection member will prevent movement of a ski to the crossed position in one direction while simultaneously permitting movement of the ski in the opposite direction by flexing the resilient projection downwardly onto the upper surface of the ski. In the ski brake environment, the ski boot effects a resilient flexing of the projection member down onto the upper surface of the ski when the ski boot is mounted between the ski bindings. The resilient projection member has extension members which project below the lower surface of the ski when the resilient projection member is in the upright position.

Abstract: A ski brake having a transverse carrier pivotally supported on a ski, which transverse carrier has braking legs which extend perpendicularly with respect to the longitudinal axis of the ski and are arranged at the sides of the ski and can be pivoted into and out of the braking position under spring urging. When the legs are in the braking position, they project substantially perpendicularly downwardly from the ski. The axis of rotation of the transverse carrier is supported on a holding member resiliently mounted on to the ski and effects a resilient holding of the axis of rotation at least in the braking position above and away from the upper surface of the ski.

Abstract: A ski brake has a pair of elongated braking elements which extend parallel to each other and are pivoted about their middle portions about a pivot axis extending parallel to the upper surface and transverse to the longitudinal direction of a ski so that these braking elements can pivot between a rest position parallel to the ski and a braking position transverse to the ski and digging into the snow under the ski. An actuating member or plate is displaceable toward and away from the upper surface of the ski and is linked to the upper ends of the braking elements so that its displacement toward the surface of the ski will swing the elements into the rest position. In addition this actuating member is provided with links which tend to swing the lower ends of the braking elements inwardly above the surface of the ski so that they do not project laterally from the ski during use thereof.

Abstract: A ski binding wherein a rectangular frame of the sole plate has a front portion which is coupled to the ski for pivotal movement about an axis extending at right angles to the skiing direction, and two parallel rearwardly extending arms portions of which extend between the upper and lower sections of a reinforcing device. The latter has two or more extensions with teeth received in selected notches of the arms to hold the reinforcing device at a desired distance from the pivot axis from the frame. One section of the reinforcing device has eyelets for the inwardly extending end portions of a pivotable yoke which engages the sole of a boot in front of the toe portion. The reinforcing device is adjusted lengthwise of the frame in dependency on thickness of the sole which is engaged by the yoke so as to insure that the foremost part of the boot is at or close to the pivot axis for the frame.

Abstract: A brake device for skis wherein a pair of levers are pivotally mounted on a bracket mounted on the upper surface of the ski. Each of the levers is composed of two arms wherein one arm functions as a brake wing and the other arm functions as a control element. Projections are provided on the ski binding which cooperate with the lever arms functioning as the control elements to control the movement of the levers during a pivotal movement of the ski binding to the ready or cocked position. As a result, the ski brake is held in the cocked or ready position by the ski binding mechanism rather than directly by the ski boot.

Abstract: A ski brake comprising at least one braking member which, when no load is applied by a foot, protrudes from the plane of the ski running surface, and upon application of a load by a foot lies substantially within the ski body.

Abstract: A ski brake for preventing the runaway of a ski. A pair of brake legs are pivotally mounted at each side of the ski for alternately occupying an inactive position alongside of and parallel with the ski or an active position projecting downwardly from the ski. A generally U-shaped member is connected to the brake legs and lies against the upper surface of the ski and under the ski boot when the latter is in position on the ski. The U-shaped member is so arranged as to be subjected to tension when pressed down against the ski by the ski boot with such tension being relieved when same is permitted by removal of the ski boot to spring up away from the ski and to move the brake legs into the abovementioned active position. A stepping plate and a lever are pivotally connected to each other and cooperate with the U-shaped member to effect the aforementioned movement toward the ski when the ski boot is placed in position on the ski between the ski bindings.

The springs also have detachable interfitting portions to secure the bearing member against movement longitudinally of the ski.

Abstract: A ski brake for skis utilizing a spring construction such as is illustrated in U.S. Pat. No. 4,014,563. The spring is composed of a U-shaped portion having a pair of generally parallel legs and a connecting cross-part. The heel holder of a ski binding has a projection thereon which cooperates with the U-shaped part to effectively hold down the ski brake in the cocked or ready position without requiring a direct engagement of the ski boot with the U-shaped part.

Abstract: A ski brake comprises two wings which swing to extend laterally from the ski when the latter becomes detached from the ski boot. The wings can swing about a respective pivot on a lever which is itself pivotally connected to a base plate secured to the ski. Confronting extensions of the brake wings each carry a hinge pin and the hinge pins are interconnected by a spring-biassed rod or by the flanged ends of a bending spring. The base plate also pivotally supports a pedal which is articulated to the lever and depressible by the ski boot to retract the brake wings.

Abstract: An automatically actuated ski brake is associated with a heel holding device and is activated upon opening of the heel holding device. The brake includes a pair of pivoted spur members resiliently urged into braking position. A catch or lock device is arranged for holding the pivoted members above the ski and a spring device urges the lock device into a position holding the brake members above the ski. The heel holding device is provided with a cam for moving the lock device away from locking engagement with the brake members when the binding moves to an open position. The lock device includes a camming member permitting the cam to ride upon the lock member without releasing the lock member when the heel holding member is moved to a closed position.

Abstract: A ski brake for automatic release upon lifting of a ski boot from the surface of a ski so as to prevent free flight thereof comprises a spring-loaded brake element adapted to reach downwardly below the bottom surface of the ski. A bent wire forms a bight which can be engaged by the ski boot and carries the brake element. A tread plate is disposed on the bight and is connected by another element, e.g. another bent wire, to the mounting structure for the ski brake.

Abstract: A ski brake is formed of spring wire bent so that one end, carrying a plastic brake shoe, forms one brake arm and an intermediate portion, formed into a first loop welded at the top, forms a second brake arm. A transverse portion of the wire, intermediate the pair of brake arms, is rotatably mounted in an open slot of a mounting pad secured to a ski. Extending from the first loop is a second or holding loop. The remaining end of the wire is parallel with the transverse portion and is rotatably mounted in a second open slot in the mounting pad. An anti-friction metal plate covers the mounting pad. A pair of brake stops are located inward of the extending brake arms when in a rest position adjacent the ski upper surface. Each brake stop has a serrated bottom surface clamped against a toothed pad which extends across the ski.

Abstract: A device for braking a ski upon the release thereof from a ski boot which comprises a mounting plate affixed to the upper surface of the ski and a preferably one-piece U-shaped stirrup of spring wire having a bight and a pair of offset shanks received in and swingably mounted on the mounting plate. Upon depression of the bight of the spring-wire stirrup by the ski boot, the stirrup is deformed and swings a pair of brake elements or blades into an inoperative position parallel to the longitudinal edges of the ski. The deformation of the stirrup, because of nonplanarity of the stirrup or camming formations on the mounting plate, provides a prestress thereto which, upon release of the stirrup by the ski boot, causes the brake elements to swing into an operative position where they inhibit free flight of the ski.

Abstract: A ski brake has a main spring element mounted upon the upper surface of a ski and resiliently biased into an operative position when the ski is released from the ski boot to bring into play at least one brake element, e.g. a blade. In order to protect the brake against impact with stones or the like, an additional spring element is provided between the actuator, which includes a pivotal member received in a mounting plate on the upper surface of the ski, and the blade or brake element so that the latter can yield on impact while retaining its braking function to prevent free flight of the ski.

Abstract: A ski brake for automatically braking the free flight of the ski upon the release of a ski boot therefrom comprises a mounting plate fixed to an upper surface of the ski and a bent-spring wire having a bight lying in one plane and a pair of offset portions angularly bent from the shank of the bight lying in another plane and received in passages in the mounting plate so that the pressing of the bight toward the surface of the ski resiliently deforms the wire and loads the same so that it tends to spring back into an operative position when the ski boot is released from the surface of the ski. A pair of brake elements are mounted upon the bent-spring wire so as to extend into the snow in the operative position of the brake. The brake elements are extended above the surface of the ski in this latter position so that they can be engaged by the ski boot so as to serve as actuators which can be held down by the ski boot and released when the ski boot is removed from the upper ski surface.

Abstract: A ski brake comprising at least one spade mounted in a pivot to rotate about an axis between an inactive position in which it is retracted above the ski when a boot is placed on the ski and an active position in which it projects below the sole of the ski. A mechanism is provided for moving the spade from the inactive position into the active position. The axis of the spade is inclined downwards towards the longitudinal axis of the ski and towards the front or rear of the ski so that the spade can move between its active and inactive positions by a rotation of less than 180.degree., enabling association of the brake with known step-in devices.

Abstract: A ski brake comprising an elastic system of two springs acting in the same direction on a braking blade wherein one spring is an auxiliary spring of low strength acting alone on the blade until the blade attains a critical intermediate position, the second spring being a main spring of high strength acting on the blade conjointly with the first spring during a portion of the remainder of the travel of the blade from the critical intermediate position to the active position in which the blade is forcibly embedded into the snow.

Abstract: A ski brake movable by a ski boot includes a U-shaped spring and lever member connected to pivot rods which extend outwardly beyond the edges of the ski. The spring member is inwardly and outwardly deformable. The bracket includes cam surfaces which deform the arms of the spring member when the boot presses the member downwardly, drawing the rods inwardly and rotating brake arms to positions substantially parallel with and above the bottom surface of the ski. When the boot heel is lifted, the spring lowers the brake arms so that they protrude below the bottom surface of the ski. In another embodiment, the cam surfaces are between the legs of the U, and are oppositely sloped, forcing the legs apart when the boot presses the spring portion to the top surface of the ski. In a further embodiment, each brake arm is provided with a second brake arm portion pivotally connected to the first. Webs can be connected between the two brake arms to further increase the effective braking area.

Abstract: A ski brake having at least one pivotal blade capable of being embedded into the snow and wherein the blade is urged to an inactive position by an elastic member of low tension. An elastic return member of a step-on pedal exerts a positive action on the blade only during raising of pedal to cause the blade to travel to its active position, while freeing the blade during the descent of the pedal in order to permit the low tension elastic member to return the blade to inactive position.

Abstract: A ski brake for a ski embodying two brake vanes pivotable from a preparatory position above the running surface of the associated ski downwardly into a ski braking position. The brake vanes also can be retained against the action of springs in a position above the ski running surface in a so-called arrested position for storage and transport of the skis. Movable latch bolts cooperate with the brake vanes to ensure that the arrested position is assumed only when the ski boot is released from the ski. A pressure plate engageable by the ski boot and connected by a cable to the latch bolts moves the bolts to shift the ski brake automatically from the arrested position into the preparatory position when the ski boot is secured to the ski.

Abstract: A pair of skis are secured together by providing notched blades of a ski brake designed to prevent free flight of the ski down a slope, e.g. upon the falling of a skier. The notches in the blades are dimensioned so that when the blades straddle the respective skis, the notches of the blades of each pair of brake elements can receive the longitudinal edges of the other ski of the respective pair so that the skis are held in runner-to-runner relationship.

Abstract: A ski brake has a stirrup-shaped bent-wire actuator upon which at least one brake element is mounted for swinging movement into an operative position to limit free flight of a ski released, for example, upon the fall of a skier. The spring wire is deformed when it is held in an inoperative position by the ski boot and springs into its operative position by the restoring force produced by deformation of the spring wire. A stretcher means is provided, e.g. in the form of a toggle, to deform the spring wire to draw its shanks together.

Abstract: A safety arrangement for a ski comprising a binding having a plate and a brake in the form of a spade pivoted on the ski and normally biased by a resilient member into an active position in which the spade projects below the sole of the ski. The spade may be retracted into an inactive position against the action of the resilient member. The spade is movable into the inactive position when the plate is fitted on the ski and a skier's boot is retained in position on the plate.

Abstract: A ski binding of the type comprising a plate engageable by a skier's boot and a releasable mechanism for securing the plate on a ski and enabling the plate to separate from the ski if the skier should fall. A ski brake is supported by the plate and comprises at least one spade pivoted on the plate. A member movable by engagement with a skier's boot controls the spade so that the spade is retracted into an inactive position above the ski sole when the boot is placed on the plate and projects downwardly into an active position below the ski sole when the boot is separated from the plate.

Abstract: In a ski brake comprising a pedal for pivotally mounting on a ski and two brake prongs for projecting downwardly from the ski at opposite sides thereof, the pedal is formed from spring wire shaped to define two coplanar open loops. The adjacent ends of the loops are interconnected to form a junction which is spaced from the pivotal axis of the pedal. The junction is linked to a coupling member which extends beyond the pivotal axis and is there hinged at a point that is fixed with respect to the ski.

Abstract: A ski brake mechanism comprising at least one laterally positioned brake arm for the ski which can be rocked into a position below the plane of the running surface of the ski and an actuation portion or component which can be depressed by the ski boot. The brake arm and actuation portion are essentially formed as one-piece from a common spring wire. The brake arm essentially consists of a loop-shaped section of the spring wire, the two legs of which are mounted upon the ski by means of two transversely extending mutually spaced pivot shafts or axes. The actuation portion essentially comprises a wire section merging in a lever-like fashion at one of the two legs.

Abstract: A pair of claws is held together in retracted position on top of the ski by a detachable spring clip on a safety strap connected to the ski boot. In an uncontrolled fall, the ski bindings release the ski which then exerts a strong pull on the safety strap, detaching the clip from the claws. The claws then swing apart laterally over the edges of the ski and into braking positions underneath the ski to prevent sliding of the release ski on the snow. Upon release of the ski bindings in a mild fall, or accidentally while riding up the ski slope on a chair lift, the released ski exerts a lesser pull on the safety strap which is insufficient to detach the spring clip, causing the ski to remain tethered to the skier's leg.

Abstract: A ski brake apparatus is provided which comprises two brake arms each mounted on one side of the ski and arranged to swing under the action of a spring force into a braking position in which the brake arm partly extends under the bottom side of the ski. Each brake arm and the associated spring is integrally formed from the same spring material. Each brake arm comprises a prolongation perpendicularly bent-off and mounted onto the ski to form the swing axis. This axis is oriented parallel with the upper side and transverse to the longitudinal direction of the ski. The end of the prolongation opposite to the brake arm is bent to form a spring bracket. The end of this spring bracket is bent parallel to the swing axis and separated from this axis in longitudinal direction of the ski.

Abstract: A ski brake preventing free flight of the ski upon its inadvertent release from the ski boot comprises a U-shaped stirrup whose shanks straddle the longitudinal edges of the ski and are provided with braking elements and a pair of torsion rods connected to the shanks and received in a mounting retaining the surface of the stirrup on the ski. When the bight of the U-shaped member is held against the ski by the ski boot directly or a plate of the ski binding, the brake elements are swung upwardly to the upper surface of the ski and lie parallel to the longitudinal edges. When the stirrup is released the resilient action of the torsion rods rotates the stirrup into a position in which the brake elements project symmetrically transverse to the longitudinal edges and below the bottom surface of the ski to prevent free flight.

Abstract: Ski braking devices are described for braking skis when they become accidentally detached from skiers' boots so as to bring the skis to rest in safe positions without hurting the skiers or other persons. Each described device has a frame with spaced parallel plates extending across the ski and a braking lever pivoted between them about an axis at one edge of the ski. A pivoted holding device snaps over the lever to hold it in an inoperative position in which it lies over the ski. When putting on the ski, the skier releases the holding device, for example with his boot, but the braking lever is retained in the inoperative position by the boot. On being released, the holding device is swung away from the braking lever by spring action. When the ski becomes detached, a spring swings the braking lever through about 270.degree. so that it projects downwards into the snow.

Abstract: Run-away preventing device for skis. A pair of prongs are pivotally mounted at each side of a ski for alternately occupying an inactive position alongside of and parallel with the ski or an active position projecting downwardly from the ski. A generally U-shaped member is connected to said prongs and lies against the upper surface of the ski and under the ski boot when the latter is in position on the ski. Said U-shaped member is so arranged as to be subjected to tension when pressed down against the ski by the ski boot with such tension being relieved when same is permitted by removal of the ski boot to spring up away from the ski and move said prongs into the above-mentioned active position. Said generally U-shaped member and the prongs connected thereto comprise only a single movable part and hence combine a minimum of parts with a maximum of reliability.

Abstract: To arrest a ski runner upon its release from the skier's boot, two spurs are pivoted to a lateral face of the runner and are coupled together for joint rotation in opposite directions. A treadle rigid with or otherwise secured to one or both spurs overlies the upper runner surface in the region of the skier's boot so as to be depressed onto that surface when the boot is tied to the runner, thereby elevating the spurs into an aligned position alongside the runner against a spring force which may be that of an elastic part of the treadle. Upon detachment of the boot from the runner, the spring force swings the spurs downwardly and toward each other whereby their points bite into the snow at opposite angles. The pair of spurs may be duplicated on opposite sides of the runner for increased effectiveness.

Abstract: A device for mounting a brake on a ski having a safety fastening comprising a longitudinal slide bar attached to the ski comprises a brake element slidably mounted on the slide bar. The brake element is secured in place and is so fitted that it cannot be detached from the slide bar in the transverse direction.
