Definitions
- the invention relates to a ski brake according to the preamble of claim 1.
- a ski brake of this type is described, for example, in DE-OS 31 36 079.
- sections of two angled wire bracket parts are guided in a guide of the operating pedal.
- the facing end sections of the wire brake arms meet a connecting spring, which is also arranged in the operating pedal.
- the pivoting in of the two brake arms is brought about in that when the actuation pedal is depressed, a contact body fastened to the base plate acts on the connecting spring in the longitudinal direction of the ski, as a result of which the braking device stretches.
- the aim of the invention is to further develop a ski brake of the type mentioned at the outset in such a way that the braking device has an increased swiveling capacity and can therefore be used effectively in conjunction with a swivel plate or a touring plate. Furthermore, the ski brake should be stable in every position.
- the connecting spring carries a crossbar with which it is supported on or in a guideway of the base plate
- the designer can design the connecting spring and the crossbar according to the desired retraction path.
- the connecting spring rest on the front boundary wall of an opening in the actuation pedal, the pivotable parts of the ski brake are given additional stability.
- This stability is further increased by the fact that two set-up springs are used which hold the connecting spring in position on the base plate. This also has the advantage of simple assembly of the braking device.
- DE-OS 25 54 110 and AT-PS 374.114 show ski brakes with one-piece brake arms bent from spring wire, so they are further away from the subject of the invention.
- an actuation pedal is provided in the longitudinal direction of the braking device, approximately V-shaped in cross section, the height of which approximately corresponds to the wire diameter.
- the retraction of the two wire brake arms within the ski outline is achieved in the last phase of depressing the actuation pedal, but the extent of this pivoting is limited by the wire dimensions due to the design.
- DE-OS 25 54 110 the use of a ski-fixed stop in connection with a one-piece brake bracket is known.
- the features of claim 4 ensure a particularly compact structure of the ski brake.
- the connecting spring is formed by a plastic spring
- the supporting web of the plastic spring can be dimensioned independently of those areas of this spring which are articulated on the mutually facing sections of the two wire brake arms.
- An embodiment according to the features of claim 8 enables a particularly simple and expedient design of the holder of the connecting spring.
- the desired braking position of the ski brake can also be determined independently of the length dimension of the plastic spring, whereby plastic springs of the same dimensions can be produced for different types of ski brakes, for example for adults and children.
- FIG. 1 is a longitudinal section along the line II of FIG. 2 and FIG. 2 is a plan view of FIG Fig. 3 and 4 cracks similar to Fig. 1 and 2 with the difference that the connecting spring is biased and the two wire brake arms are spread apart and the Fig. 5 and 6 cracks also similar to Figs. 1 and 2 in the standby position Braking device.
- 7 and 8 show, in mutually associated cracks, a second exemplary embodiment of the ski brake according to the invention in the braking position, FIG. 7 being a longitudinal section along line VII-VII of FIG 8 and 8 is a plan view of FIG. 7 and FIGS. 9 and 10 also show cracks similar to FIGS. 7 and 8 in the standby position of the braking device.
- 1 to 6 show a ski brake designated in its entirety with 1, the base plate 2 of which, for example, is formed in one piece with a pivotable soleplate or a touring plate or is mounted on a ski in any known manner and at one end bearing points 2a for a pivot axis 6 are provided. At a distance from the pivot axis 6, additional bearing points 2b are arranged on the base plate 2, in which sections of wire brake arms 5 to be described later are mounted. The bearing points 2b for the wire brake arms 5 are extended upwards and open.
- the base plate 2 has an approximately rectangular exemption 2c for an actuation pedal 4 articulated on the pivot axis 6.
- a guide track 2e running in its longitudinal direction and a groove 2f likewise running in its longitudinal direction.
- the actuating pedal 4 is approximately rectangular and, in its upper surface designed as a tread surface 4a, has an approximately square opening 4b symmetrical to its longitudinal axis and at a short distance from the pivot axis 6.
- Side walls 4c and a front wall 4d of the operating pedal 4 are bent toward the top of the ski.
- the side walls 4c are provided with elongated rounded recesses 4e for the wire brake arms 5.
- the side walls 4c In the pedal section remote from the pivot axis 6, the side walls 4c have cranked tabs 4f in the direction of the longitudinal axis of the ski brake 1.
- the Opening 4b in the operating pedal 4 is equipped with boundary walls, the front being 4h, the side 4i and the rear 4j.
- the front boundary wall 4h has an exemption 4k.
- the front section of the actuation pedal 4 forms a guide 4g for the sections of the wire brake arms 5, which is delimited by the tread plate 4a, the side walls 4c, the front wall 4d, the tabs 4f and the front boundary wall 4h of the opening 4b.
- the wire brake arms 5 consist of a multi-curved spring wire and, as can be seen particularly from FIGS. 2, 4 and 6, are designed symmetrically. As can be seen in FIG. 6, sections 5a of the wire brake arms 5 are arranged approximately parallel to the longitudinal axis of the ski brake 1 in the plan view. These sections 5a can be provided, for example, with a plastic injection, not shown here, and are referred to below as brake mandrels. Sections 5b of the wire brake arms 5 adjoin the brake mandrels 5a at an acute angle to the longitudinal axis of the ski brake 1. Further cross sections 5c, each acting as a pivot axis of the individual wire brake arms 5, are connected to it.
- the cross sections 5c of the wire brake arms 5 are pivotally mounted in the bearing points 2b of the base plate 2. This is followed by further wire sections 5d, which extend parallel to the longitudinal axis of the ski brake 1 and extend within the actuation pedal 4 and are held by the tabs 4f. Further brake arm sections 5e each run at an obtuse angle to the longitudinal axis of the ski brake 1. They carry a connecting spring 7, which is equipped with legs 7a, the end regions of which form a loop 7b. A part of the loop 7b designed as a crosspiece 7c runs in the guideway 2e of the base plate 2.
- Leg springs serving as set-up spring 8 are arranged around the pivot axis 6, their side walls 4c of the actuating pedal 4 adjacent legs 8a act on the actuation pedal 4 in the direction of the active braking position of the ski brake 1, while the legs 8b of the positioning springs 8 adjacent to the longitudinal axis of the ski brake 1 hold down the crosspiece 7c, at least one hook portion 8c of the legs 8b engaging over the crosspiece 7c.
- the connecting spring 7 lies at least partially against the front boundary wall 4h of the opening 4b, the actuating pedal 4 being simultaneously pushed up by the leg spring 8.
- the connecting spring 7 is slightly bent and the brake mandrels 5a extend at a short distance from the side surfaces of the ski brake 1 or the ski (not shown here) (see FIG. 2).
- the brake mandrels 5 simultaneously perform an outward movement and then back again during the pivoting movement from the ready position to the braking position inside towards the ski. On the one hand, this prevents damage to the side surfaces of the ski, which is not shown here, and on the other hand, when using the ski brake according to the invention with a plate binding, an obstacle to the braking process by the pivotable sole plate is excluded.
- FIG. 7 to 10 show a ski brake designated in its entirety by 10, the base plate 20 of which is formed, for example, in one piece with a pivotable soleplate or a touring plate or is mounted on a ski in any known manner and at one end bearing points 20a for a pivot axis 60 are provided. At a distance from the pivot axis 60, additional bearing points 20b are arranged on the base plate 20, in which sections of wire brake arms 50 to be described later are mounted. The bearing points 20b for the wire brake arms 50 are expanded at the top and open.
- the base plate 20 has an approximately rectangular wide position 20c for an actuation pedal 40 articulated on the pivot axis 60, the clearance 20c being limited by a floor 20d.
- the actuating pedal 40 is approximately rectangular and has an opening 40b in its upper surface designed as a step surface 40a symmetrical to its longitudinal axis and at a short distance from the pivot axis 60. Sidewalls 40c and a front wall 40d of the operating pedal 40 are bent toward the ski surface. The side walls 40c are provided with elongated rounded recesses 40e for the wire brake arms 50. In the pedal section remote from the pivot axis 60, the side walls 40c have tabs 40f bent toward the longitudinal axis.
- the opening 40b in Actuator pedal 40 is equipped with boundary walls, the front with 40h, the side with 40i and the rear with 40j. Through the opening 40b, snow that may be accumulating can be pressed out.
- the front section of the actuation pedal 40 forms a guide 40g which is defined by the tread plate 40a, the side walls 40c, the front wall 40d, the tabs 40f and the front boundary walls 40h of the opening 40b for sections of the wire brake arms 50 which will be described in more detail later.
- the wire brake arms 50 consist of a multi-curved spring wire and, as can be seen particularly from FIGS. 8 and 10, are designed symmetrically. As can be seen in FIG. 10, sections 50a of the wire brake arms 50 are arranged approximately parallel to the longitudinal axis of the ski brake 10 in plan view. These sections 50a can, for example, be provided with a plastic injection, not shown here, and are referred to below as brake mandrels. Sections 50b of the wire brake arms 50 adjoin the brake mandrels 50a at an acute angle to the longitudinal axis of the ski brake. Further cross sections 50c, each acting as a pivot axis of the individual wire brake arms 50, are connected to it.
- the cross sections 50c of the wire brake arms 50 are pivotally mounted in the bearing points 20b of the base plate 20. This is followed by further wire sections 50d, which extend parallel to the longitudinal axis of the ski brake 10 and extend within the actuation pedal 40 and are held by the tabs 40f. Further brake arm sections 50e each run at an obtuse angle to the longitudinal axis of the ski brake 10.
- the brake arm sections 50e carry a connecting spring 70 which is equipped with a link 70a which, as can be seen in FIG. 7, is approximately in the active braking position of the ski brake 10 Extends towards the top of the ski.
- the connecting spring 70 is, as can be seen particularly clearly in FIG.
- Connection springs 70 each have a projection 70e directed away from the longitudinal central axis.
- the link 70a of the connecting spring 70 consists of a shaft 70b and a crossbar 70d, the crossbar 70d being extended by lateral extensions 70f.
- Leg springs serving as set-up springs 80 are arranged around the pivot axis 60, their legs 80a adjacent to the side walls 40b of the actuation pedal 40 acting on the actuation pedal 40 in the direction of the active braking position of the ski brake 10, while the legs 80b of the set-up springs 80 adjacent to the longitudinal axis of the ski brake 10 den Hold cross bar 70d down. At least one hook section 80c of a leg 80b encompasses the transverse web 70d. This overlapping can take place in the center or, as shown, by two hook sections 80c of both legs 80b on extensions 70f of the crosspiece 70d.
- the connecting spring 70 lies at least partially against the front boundary walls 40h of the opening 40b, the actuating pedal 40 being pressed up simultaneously by the leg spring 80.
- the lugs 70e of the connecting spring 70 have a slight angular position with respect to a line which is intended to be transverse to the longitudinal axis of the ski, and the brake mandrels 50a extend at a short distance from the side faces of the ski brake 10 or the ski (not shown here) (see FIG. 8).
- the lugs 70e of the connecting spring 70 In the first phase of depressing the actuation pedal 40, the lugs 70e of the connecting spring 70 initially assume a position which is essentially transverse to the longitudinal axis of the ski, as a result of which the brake mandrels 50a pivot outwards.
- the inclined sections 50e of the wire brake arms 50 move further forward in the guide 40g, so that the transverse web 70d of the connecting spring 70 is supported at the rear end of the clearance 20c, as a result of which the lugs 70e of the connecting spring 70 one in Compared to the braking position of the ski brake 10, assume a larger angular position with respect to a line that is transverse to the longitudinal axis of the ski. In this way, the wire brake arms 50a are brought into their retracted position closest to the longitudinal axis of the brake (see FIG. 10).
- the brake mandrels 50 simultaneously perform an outward movement and then an inward movement towards the ski during the swiveling movement from the ready position to the active braking position. This prevents damage to the side surfaces of the ski, which is not shown here.
- an obstacle to the braking process by the pivotable sole plate is also excluded.
- the legs of the connecting spring could also be designed as a separate component made of metal or plastic, or the connecting spring could at the same time be designed as a positioning spring.
- the transverse web of the connecting spring could also be held by a holding element separate from the positioning spring.
- the leg or a hook portion thereof can also engage in a recess of the crossbar and be fastened to it.
