Definitions
- the present invention relates to a device for performing jumps by successive hops.
- the type of device covered by the invention has already been widely described in numerous publications, such as US patent 4,390,178.
- This patent describes a machine essentially comprising a tube inside which slides an impact rod whose deployment towards the ground is ensured by means of a compression spring.
- the improvement made on this machine resides in the fact that the handlebar with handles and the footrest shims, fixed respectively to the upper and lower end of the tube by means of a pin, can pivot around the axis of the tube and are interconnected via rigid metal rods.
- Such a configuration makes it possible to maintain the handlebars and the shims in a quasi-horizontal position, whatever the inclination given to the impact rod.
- the object of the invention is to overcome this drawback and to propose a jumping device of the type mentioned above which allows an uninformed user to familiarize himself with said device in complete safety.
- Another object of the invention is to provide a jumping machine which can be used in extreme conditions such as those of a sports competition.
- the subject of the invention is a device for performing jumps by successive hops comprising:
- a handlebar provided with handles, integral with the other end, called the upper end, of the body, an impact rod adapted to slide inside the body and at least part of which is able to deploy in the extension of the lower end of the body,
- the device is characterized in that it comprises means for braking the impact rod relative to the body and means for manual control of said braking means arranged at the level of the handlebar.
- the device according to the invention can be used in extreme conditions since the braking means can instantly block the sliding of the impact rod relative to the body.
- the foot rest wedges are produced in a single machined part provided with an axial passage adapted to slide the impact rod, said machined part being screwed to the lower end of the tubular body.
- the handlebars are connected to the upper end of the body by means of a bracket.
- the elastic return means comprise a helical spring.
- the braking means comprise at least one friction surface adapted to come to bear radially against the rod.
- the rod is hollow and the floating surface comes to rub inside of it.
- the friction surface is advantageously a cylindrical elastomer ring.
- the braking means comprise a sleeve adapted to radially deform the cylindrical ring.
- the sleeve comprises in its lower part, tabs each having an inclined face, arranged concentrically and around which the cylindrical ring is mounted by force.
- a needle having a conical head is inserted between the legs coming into contact with each inclined face, the manual control means being adapted to move said needle axially in order to cause the radial spacing of said legs.
- the device comprises means for elastic return of the needle.
- the device comprises a sheath screwed to the upper end of the tubular body and extending longitudinally inside the latter, so as to accommodate the cables fixed to the braking means.
- the braking means are preferably fixed to the lower end of the sheath.
- the device according to the invention advantageously comprises a ball bushing adapted to guide the rod along the axis of the body during its sliding inside the latter.
- FIGS. 1 to 2b which respectively represent:
- FIG. 1 a general perspective view of an embodiment of a device according to the invention
- FIG. 2 a view in longitudinal section of the device of FIG. 1 along the axis A-A,
- FIGS. 1 to 2b a sectional view of a variant of the device according to the invention.
- the device shown by way of example in FIGS. 1 to 2b is intended to perform jumps by successive hops and has been specially designed for users wishing to practice a sport that combines a sense of balance and physical endurance.
- this device 1 essentially comprises a tubular body 2 whose lower end is provided with two footrest wedges 3, 4 and in the extension of which an impact rod 5 is adapted to deploy down.
- This impact rod 5 adapted to slide inside the tubular body 2 has in its lower part a shoe 51 made of a material with a low coefficient of friction.
- a sheath 6 is fixed to the tubular body 2 at the upper end thereof.
- This sheath 6 includes a tip 61 in which is housed a bracket 7 of the type used to equip the bicycles designated under the name "mountain bike”.
- a handlebar 8 provided with two handles 81, 82 is fixed to said stem 7 so that it extends transversely to the tubular body 2.
- a handle 83, 84 is mounted, in a manner known per se, on each handle 81, 82.
- On each handle 83, 84 is fixed a cable 85, 86 provided with a sheath and connected to the braking means 9, described below in detail.
- Figure 2 is a longitudinal sectional view of the device of Figure 1 along the axis A- A.
- the tubular body 2 has at each of its ends a thread 21, 22.
- the impact rod 5 is hollow and has at its upper end a metal ring 10 mounted by force.
- This metal ring 10 comes to bear against the lower part of a helical spring 11.
- This compression spring 11 is adapted to bring the impact rod 5 to an extreme deployed position.
- the characteristic sizes of this spring 11 have been determined to avoid any contact between the lower part of the foot rest wedges 3, 4 and the shoe 51, even under extreme conditions of use. It should be noted that this spring 11 is interchangeable according to the weight of the user.
- the footrest wedges 3, 4 are perforated and each provided on their upper face with studs 31, 41. These wedges 3, 4 are made in one single machined part 12 made of a light material such as aluminum. This machined part 12 is provided with an axial passage 121 adapted to slide the impact rod 5, and is screwed to the lower end of the tubular body 2.
- a ball bushing 13 adapted to guide the impact rod 5 along the axis of the body 2 during its sliding inside the latter is housed inside the axial passage 121.
- This ball bushing 13 is held in place in its housing by means of an annular plate 14 fixed to the machined part 12 by means of screws 15.
- the sheath 6 comprises, at its lower end, a bulge 63 adapted to accommodate a cylindrical sleeve 91 which constitutes part of the braking means 9 in accordance with the invention (FIG. 2a).
- the sleeve 91 has, in its lower part, lugs 911 each having an inclined face 912 arranged concentrically, so that they form a cavity 913 having a symmetry of revolution of axis coincident with the axis A- A of sliding of the impact rod 5.
- a cylindrical elastomer ring 92 is force-fitted around lugs 911 and constitutes the brake lining according to the invention.
- the braking means 9 also comprise a needle 93 pierced with a channel 931 in which the cables are housed.
- the conical head 932 of this needle 93 is housed in the cavity 913 formed by the legs 911 coming into abutment against the inclined faces 912.
- the needle 93 comprises, at the opposite end of the head 932, a thread 933 in which is screwed a knurled nut-lock system 94.
- This nut-lock system 94 keeps a compression spring 95 in place, the upper end of which rests on a washer 96.
- the washer 96 itself comes to bear on the underside of the cylindrical ring 92.
- the cables are kept tight at their free end, in a cable clamp 97 by means of two screws 971, 972.
- the displacement of the needle 93 causes a radial spacing of the lugs 911.
- the ring 92 is then deformed radially (FIG. 2b) and its external side wall 921 comes to rub against the internal wall 52 of the impact rod 5, which causes the braking of the latter relative to the tubular body 2.
- the compression spring 95 returns to the free state and thus returns the needle 93 to the position it initially occupied before braking.
- FIG. 3 is a sectional view of a variant of the impact rod 5.
- the impact rod 5 consists of two parts 5a, 5b linked together by means of a threaded rod 52 which also serves to hold the shoe 5.
- the smallest part 5b of the impact rod arranged in the lower part of the rod can be replaced by any other part of identical shape and of different length.
- the length of this part 5b is adjustable according to the size of the user.
- the particular structure of the braking means 9 described above can completely be replaced by an equivalent structure, such as jaws with jaws adapted to tighten one or more brake lining (s) arranged concentrically. outside the impact rod 5.
- the compression spring of the preferred variant making it possible to return the impact rod can be arranged in a different way, such as for example being arranged around the rod d impact under the footrests. It can also be progressive, which makes it easier to make the first jumps. It can also be replaced by any other equivalent means adapted to return the impact rod to its extreme deployed position such as pneumatic means.
