Description

rehabilitation (1).

  The present invention relates to a striking drive system for

  combat sports (boxes, karate, etc ...).

  The basic equipment for training in combat sports is the

punching and punching ball.

  The punching bag, due to its cylindrical shape, allows horizontal strikes at different heights (for example head, chest, and aWomen). However, the frap bag

  pe is not suitable for up and down strikes.

  The punching ball is in the form of a balloon placed between 2 elastics.

  The punching ball, due to its rounded shape, allows strikes from different angles (horizontal, up and down), but at a single height (for example

full chest or head).

  These different equipments therefore do not allow the user training

  complete with strikes both from different angles and at different heights.

  The object of the invention is to remedy this drawback.

  According to a first characteristic, the striking system according to the invention comprises:

  - a tube suspended from a fixing placed high up.

  - several striking elements placed along the tube using a hole in their central part, these striking elements having in their upper and lower part a shape approaching a half of a ball or a half of ball flattened in the direction of the height, so as to allow the horizontal strikes, rising and falling,

  these strikes being possible all around the striking elements.

  - at least one intermediate element placed between the striking elements and having a

  outer diameter smaller than the outer diameter of the impactor elements.

  - stops placed on the tube so as to keep the striking elements in position.

  According to a second characteristic, the striking system according to the invention comprises:

  - a tube suspended from a fixing placed high up.

  - several striking elements placed along the tube using a hole in their central part. - at least one striking element having in its upper and lower parts a shape approaching a half of a ball or a half of a ball flattened in the direction of the height, so as to allow the strikes ho ri zontale s, rising s and scending s,

  these strikes being possible all around the striking elements.

  - at least one striking element of cylindrical shape.

  - stops placed on the tube so as to keep the striking elements in position.

  For example, a striking element whose upper and lower parts have a shape approaching a half of a ball or a half of a flattened ball - 2 in the direction of the height may have the shape of a ball, a flattened ball in the direction of the height or a cylinder whose sides have the shape of a half of a ball or a

  half of ball flattened in the direction of the height.

  Note that a striking element can see its initial shape modified after mounting on the tube and compaction, in particular by a flattening in the height direction. For example a striking element having the initial shape of a ball can after mounting on the

  tube and compaction have the shape of a flattened ball in the direction of the height.

  According to particular embodiments: - at least one stop may be removable in order to allow the replacement of s elements of

  strikes and intermediate elements.

  - at least one stop can be adjustable in positioning.

  - Each impactor can be the subject of different embodiments: - it can be made of synthetic foam

- it may include an envelope.

  - The envelope may include at least one opening / closing device so that one

  can add or remove filler material.

  - a striking element can contain at least one sealed chamber which can be replaced

  fold with compressed air or liquid.

  - The striking system may include a device for varying its weight.

  - This device can for example be in the form of plugs placed towards the ends of the tube so that the space between the plugs can be filled with maté

  or elements which make the impact system heavier.

  - The device for varying the weight of the impact system can also be in the form of elements having a hole in their center and which can be

placed on the tube.

  - In other embodiments the tube can be replaced by a bar, a cable

or a chain.

  - The striking system tube or bar can be made of an elastic material

deformable.

  - The striking system can be suspended by means of a device comprising

  at least one elastically deformable element.

  - The lower part of the impact system can be connected to a lower fixing.

  - The impact system can be connected to one of the upper or lower fixings by

  through a length adjustable strap.

  - A shock absorber for possible shocks against the ground can be placed at the bottom of the impact system. This shock absorber can for example be an element produced in a

  elastically deformable material.

  - The impact system can be suspended from a top attachment via - 3

  a height adjustment device.

  - The height adjustment device can be in the form of a rope passing through at least one pulley, a self-locking device allowing the rope to slide freely in the direction of the rise of the striking system and to be blocked in the other direction, a device (for example a cord) allows both to unlock the self-locking device to allow the descent of the system

typing.

  - The impact system can be supplemented by a cone-shaped accessory on which

  a striking element can be inserted in order to compact the materials it contains.

  The invention will be better understood with the description which follows, opposite

  attached drawings which are given by way of non-limiting example only.

  The various figures will now be detailed in the following paragraphs. Figure 1 shows an overview of the striking system with a sportsman in

  performing a horizontal punch from the front on the upper striking element.

  The striking system is shown in an embodiment where it has 2 elements

  of striking in the form of flattened balls.

  Figure 2 shows a longitudinal section of the striking system in one mode

  where it has 2 striking elements in the form of flattened balls.

  On the tube (1) are placed the 2 striking elements (2) separated by elements

  spacers (3) which are in the form of superimposed rings. Inter-

  Calaires (3) are also placed above the upper striking element and below the lower striking element. The impact elements and the intermediate elements are held in place by 2 stops. The upper stop is in the form of a clamp (4) placed above a washer (5). The upper stop (4) is removable and adjustable in positioning along the tube (1), by example to compensate for a compaction of the striking elements (2) and the intermediate elements (3). The lower stop is in the form of a bolt (6) passing through a hole made in the tube, stopped by a nut and surmounted by a washer (5). One or more intermediate elements can

  be made of an elastically deformable material (for example synthetic foam

  tick) so as to keep the impact elements compressed between the 2 stops. Ele-

  elastically deformable spacers can also allow sliding

  striking elements on the tube during up and down strikes.

  In embodiments not shown, one or more interlayer elements

  res can be replaced by a steel spring or by any equivalent means (for example an elastically deformable element made of rubber or plastic), so as to keep the striking elements compressed between the stops and possibly to allow the sliding elements to slide. hits the tube during up and down strikes.

  The impact system is suspended from a high-level fixing by means of the

  median of a rope (7) and several elastics (8) placed between 2 triangular links

  res (9). Elastics allow in particular to absorb downward strikes. The lower mail is connected to the striking system by means of a swivel (10). A bolt (11) stopped by a nut enables the tube (1) of the Dappe system to be secured and

  the swivel (10). The swivel is held in the center of the bolt using 2 spacers (12).

  In an embodiment not shown, the 2 triangular links can include

  wear an opening / closing device.

  Inside the tube are placed 2 removable plugs (13, 14). The space between the 2 plugs can be filled with various materials or elements in order to weigh down the impact system (for example water, sand, metal cylinders, etc.). A cord (15) removes the upper plug (13) for filling the tube after dismantling the upper bolt (11). The lower plug (14) is traversed by a hole into which the bolt from the lower part of the tube (6) is inserted. The lower plug (14) is made of an elastically deformable material (for example rubber) and protrudes from the lower part of the tube so as to serve as a shock absorber for possible impacts against the ground. - 6 The arrows show examples of different possible striking angles:

A: horizontal strikes.

B: rising strikes.

C: descending strikes.

  Strikes are of course possible in the intermediate angles to those indicated.

only by the arrows.

  The presence of striking elements in the form of flattened balls makes it possible to strike from different angles (A, B. C). The presence of at least 2 striking elements

  makes it possible to strike at different heights.

  The invention therefore allows the user to practice hitting at the same time under

  different angles (A, B. C) and at different heights.

  The presence of at least one removable stop (4 and 6) makes the striking system removable. The user can thus replace the striking elements and the intermediate elements. In embodiments not shown, the upper and lower visible parts of the tube can be protected by covers made of a material

  elastically deformable (for example synthetic foam).

  Figure 3 shows a top view of the impact system in the embodiment of Figure 2 and after disassembly of the suspension device (rope, elastic

ques and swivel).

  Figure 4 shows a longitudinal section of the impact system in the embodiment of Figure 2 supplemented by a removable elastic (16) which connects the lower part of the impact system to a lower attachment (17). ) is attached to a removable link (18) placed in a housing inside the lower plug (14). The link (18) is held in position by the bolt (6). The lower attachment can for example be placed on the ground or on a heavy weight placed on the ground. The elastic band (16) makes it possible to limit the amplitude of the movements of the striking system while increasing

  so quickly are these movements.

  The possibility of placing or removing the removable link (18) and the elastic (16)

  allows the impact system to be used with or without a link with a lower attachment.

  Figures 5 to 16 show examples of different embodiments

of a striking element.

  These different embodiments all have in common that the upper parts

  re (S) and lower (I) of a striking element have a shape approaching a half ball or a half ball flattened in the direction of the height, so as to allow horizontal strikes (A ), rising (B) and descending (C), these strikes (A, B. C)

  being possible all around the striking elements.

  The other construction details (tube, stops, suspension device, etc.) are identical to those in FIG. 2, only the length of the impact system varies.

  than the number of striking elements and intermediate elements.

  As in the previous example, the arrows show the different possible typing angles. The presence of striking elements in the form of flattened balls allows

  strikes from different angles (horizontal (A), up (B) and down (C)).

  The presence of at least 2 striking elements allows strikes at different heights.

  Figure 18 shows a front view of the impact system in the embodiment of Figure 17 supplemented by a removable elastic (16) which connects the part

  lower of the impactor system to a lower fixing (17).

  Figures 2, 3, 4, 17, 18 show the impact system produced in heavy versions. Figure 19 shows a front view of the impact system produced in a medium-weight version. The striking system described here has 4 striking elements in the form of flattened balls. The other construction details (form, spacers, stops, etc.) are identical to those of the previous embodiments - 8

  but with smaller dimensions so as to reduce the weight.

  As in the previous examples, the arrows indicate that strikes are possible both from different angles (horizontal (A), up (B) and down

  dant (C)) and at different heights.

  Figure 20 shows a front view of the impact system in the embodiment of Figure 19 supplemented by a removable elastic (16) which connects the lower part

  of the impactor system to a lower attachment (17).

  Figure 21 shows a front view of the impact system made in a light version. As it weighs less than the previous models, it can

  be suspended by a single elastic band (8). The model shown here has 5 elements of frap-

  eg in the form of flattened balls. The other construction details (tube, interchangeable elements

  laires, stops, etc ...) are identical to those of the previous embodiments, but with

  smaller dimensions to reduce weight.

  As in the previous examples, the arrows indicate that strikes are possible both from different angles (horizontal (A), up (B) and down

  dant (C)) and at different heights.

  Figure 22 shows a front view of the striking system in the embodiment of Figure 21 supplemented by a removable elastic (16) which connects the lower part

  of the impactor system to a lower attachment (17).

  In an embodiment not illustrated, a length-adjustable belt can

  be placed between the impact system and the upper attachment or the lower attachment.

  This belt allows in particular to increase the tension of the elastic bands (8, 16).

  FIG. 23 shows a front view of the striking system in an embodiment where it comprises a striking element in the form of a flattened ball (2), and a striking element of cylindrical shape (33). The other construction details (tube, elements

  dividers, stops, etc ...) are identical to those of Figures 2 and 3.

  The presence of a striking element in the form of a flattened ball allows the strikes from different angles (horizontal (A), up (B) and down (C)) and the

  presence of at least 2 striking elements allows strikes at different heights.

  It should be noted that the presence of at least one removable stop (4 and 6) makes the striking elements and the removable intermediate elements. The user can thus configure his typing system in different ways (choice of number, shape and size

striking elements).

  For example, a user with the typing system in real mode

  sation of figure 2 (with 2 flattened balls) can transform it in the embodiment

  tion of figure 23 (with 1 flat ball and 1 cylinder) and vice versa.

  As in the previous examples, the hitting system can be easily

  tative, be connected to a lower attachment (not shown in the drawing).

  FIG. 24 shows a front view of the striking system in an embodiment where it is of weight and has 3 striking elements in the form of flat balls (34) which allow the horizontal strikes (A), rising ( B) and descending (C) and

  a cylindrical striking element (35) which allows horizontal strikes.

  As in the previous examples, strikes are possible both under

  different angles and at different heights.

  As stipulated in the previous example, the presence of at least one removable stop (36, 37) allows the user to configure the striking system of different

your ways.

  The user can for example transform the striking system of the embodiment of FIG. 21 (with 5 flattened balls) into that of the embodiment of the fig.

  re 24 (with 3 flattened balls and 1 cylinder) and vice versa.

  As in the previous examples, the striking system can

  optional, be connected to a lower fixing (not shown in the drawing).

  FIG. 25 shows in longitudinal section the striking system in an embodiment where it comprises two striking elements in the form of flattened balls (38) and where the tube is replaced by a cable (39). The striking elements (38) and the intermediate elements (40) are held in position between 2 stops. The lower stop (41) consists of a

  welded or crimped metal element on the cable and surmounted by a washer (42).

  The upper stop consists of a clamping ring (43). It is removable and adjustable in positioning along the cable. The clamping ring is placed on a washer (42). The cable (39) is connected to an upper attachment by means of a rope (7), several elastic bands (8) placed in triangular links (9) and a

swivel (10).

  The possible striking angles and heights are similar to those in Figure 2.

  In embodiments not shown, the lower part of the impact system can be connected to a lower fixing placed on the ground or on a weight placed on

floor.

  Figure 26 shows a top view of the embodiment of Figure 25

  (the cable (39) being shown cut above the impact system).

  The examples of the preceding figures show embodiments where the

  impact system has between 2 and 5 impact elements.

  In embodiments not illustrated, the striking system may include

ter more than 5 striking elements.

  The more striking elements, the smaller they will be.

  Whatever the number of striking elements, at least one of them must contain upper and lower sp arties having a shape resembling a half of a ball or half of a flattened ball in the height direction, so as to allow - 10 horizontal (A), upward (B) and downward (C) strikes, these strikes (A, B, C) being

  possible all around the striking elements.

  The presence of at least 2 striking elements allows strikes at different

  heights (for example 2 flattened balls or a flattened ball and a cylinder).

  The invention thus allows strikes both from different angles (A, B. C) and

different heights.

  FIG. 27 shows a longitudinal section of a striking element composed of an envelope (44) containing a filling material (45). The envelope (44) can be for example of leather, fabric or plastic and the filling material (45) can consist of pieces of fabric, cotton fluff, sand, various granules or all equivalent materials. The part of the envelope which is close to the hole can be reinforced (46). The filling material can be introduced through the hole in the

  central part of the impactor.

* Figure 28 shows a top view of the impactor of Figure 27.

  FIG. 29 shows a longitudinal section of a striking element where the envelope (47) comprises, on a reinforced part (48), openings closed by horns (49). These openings allow you to add or remove fill material

ge (5o).

  Figure 30 shows a top view of the impactor of Figure 29. Figure 31 shows a method of compacting the contents of the envelope by

  the impact of the impactor on a conical accessory (51).

  In other embodiments, the envelope can be placed around a synthetic foam element or by molding the envelope around the foam element

  either by injecting foam inside the envelope.

  A striking element can also be produced using a block of synthetic foam, without an envelope. In another embodiment, an ilappe element can contain one or more sealed chambers which can be filled with compressed air or a liquid. Figure 32 shows a front view of the lower plug (14) placed in the tube. This plug can for example be made of rubber. It has a hole (52) into which the bolt placed at the bottom of the tube is introduced. The cap com carries a housing (53) in which one can place a metal link making it possible to connect

  the lower part of the impact system to a lower fixing.

  Figure 33 shows a side view of Figure 32.

  Figure 34 shows a front view of the lower plug (14) in which the

  metal link (18) has been placed.

  Figure 35 shows a side view of Figure 34.

  Figure 36 shows a front view of another embodiment of a stopper - 11 than that of Figures 1 to 26. The tube (56) has a series of holes (54). In one of these holes is introduced an axis or a bolt (55) stopped by a nut (not visible on the side of the sin). This bolt comes to rest on a washer (5) which rests itself on the elements

dividers (3).

  Figure 37 shows another embodiment of a stop. The tube (57) has a thread (58) on which is screwed a ring (59) whose internal part is threaded. The ring has a protuberance in which a hole (60) makes it possible to introduce a rod to rotate the ring on the thread. The ring comes to rest on a washer

  the (5) which comes to bear on the intermediate elements (3).

  Figure 38 shows a schematic side view of a bracket used to hang the impact system. On the stem (61) are hung pulleys (62 and 63) on which passes a rope (64) which serves to suspend the impact system (not shown in the drawing and placed under the strand (64 A) of the rope) . One of the pulleys (63) is provided with a self-locking device (65) which lets the rope slide freely when it is pulled (strand 64 B) to raise the striking system. The self-locking device blocks the rope to prevent the impact system from lowering. A pull on a cord (66) enables the self-locking device to be released in order to lower the impact system. The pulley fitted with the self-locking device is placed near the wall so as to avoid

  that the cord (64 B) and the cord (66) do not hang too close to the impact system.

  Figure 39 shows a schematic side view of a bracket identical to that of Figure 38, with the mounting of an additional pulley (67) which allows for hauling so as to reduce the effort required to hoist the system of frap pe. Figure 40 shows a schematic side view of a suspension device made using 2 fasteners (68, 69) placed under the plank or under a beam. The operating principle of the rope (64), the pulleys (62, 63), the autoblo quant device (65) and the cord (66) is identical to that of FIG. 38. One of the 2 fasteners ( 69) is placed away from the striking system to prevent the cord (64 B)

  and the cord (66) do not hang too close to the impact system.

  Figure 41 muk a schematic side view of a suspension device made using 2 fasteners, one is placed under the ceiling or under a beam (70) and the other on a wall (71). The assembly comprises a muffling and the operating principle of the rope (64), the pulleys (62, 63, 67), the self-locking device (65) and the

  cord (66) is identical to that of Figure 39.

  As in the previous example, one of the 2 fasteners (71) is placed away from the impact system to prevent the rope (64 B) and the cord (66) from hanging down

too close to the striking system.

  Other modes of suspension of the impact system, not illustrated, can be used: - The impact system can be suspended by a rope without a height adjustment device. - The rope can be replaced by a chain or a cable, whether with or without height adjustment. - The self-locking device described in Figures 38 to 41 can be replaced by a

  hook fixed to the wall and on which you hang the rope, chain or cable.

  It is understood that whatever the suspension device used, it must be designed to be strong enough to avoid any risk of damage caused

by the fall of the striking system.

  It is understood that the various embodiments described above are not

  given only by way of example and in no way constitute a lirnitatio n of the invent io n.
