Description

The subject of the invention is a weight-training apparatus

  comprising means for disengaging the weights which makes it possible to position the

operating levers.

  The current weight machines when the weights are loaded, have a disadvantage in the levers maneuvering. These operating levers, once the weight load, are in an extreme high or low position. But it is bad to start an exercise by working on levers of maneuver that are then in

an extreme position.

  For this purpose, the apparatus according to the invention comprises a means which acts as a disengagement and which makes it possible to easily position said levers

maneuvering.

  The means of which acts as disengagement is a disengaging lever which activates, by cable, a wheel mounted on the axis of rotation of the main wheel on which is wound the cable which connects the weight laden

and the levers for maneuvering.

  In today's machines, weights are selected by a pin. In this regard, reference may be made to the patent application filed in France on April 25, 1983 under the number 83 06725 and the U.S.-A patents.

  4.333.644 (Lambert), U.S. - A 4,184,675 (ROGERSON).

  These documents describe means for selecting weights. These weights are usually 5 kilogram weights. it follows that the selection of

  these weights do not allow a very gradual weight adjustment.

  The apparatus according to the invention has weights of 5 kilograms and loads of 0.500 kilograms. According to the invention these weights of 0.500 kilogram are maintained at the upper ends of the working columns, quick attachment means keep them in this position. For these weights of 0.500 kilograms to be loaded, it is sufficient to descend them along the working columns so that they come to rest on the first weight of 5 kilograms which is itself in

load by a pin.

  The accompanying figures given as indicative and non-limiting examples will easily understand the invention. They

  represent a preferred embodiment according to the invention.

  Figure 1 is a side view of an apparatus according to the invention, the operating levers are actuated by the arms; the user is

  seated and the control lever is in a very low extreme position.

  Figure 2 is a view of the apparatus shown in Figure 1, the user has operated the release lever which is controlled by the

-2- 2561110

  foot, the maneuvering lever then comes to the level of the hands to be

operated initially without effort.

  Figure 3 is a view of the apparatus shown in Figures 1 and 2, the user actuates the operating lever which moves up and down the weights, the release lever is returned to its starting position. Figure 4 is a view of a device whose operating lever is operated by the legs, the user is lying and his legs are folded to the extreme, which is not good to start a movement, it lO it is therefore necessary to disengage the weights so that the user can

  start his movements in the best conditions.

  FIG. 5 is a view of the apparatus shown in FIG.

  the user actuates the release lever.

  FIG. 6 is a view of the apparatus shown in FIGS. 4 and 5 where the user actuates the operating lever with his legs and

  o the clutch release lever has returned to its original position.

  Figure 7 shows schematically how the clutch lever acts. Figures 8 and 9 show a perspective view showing the loads disposed on the working columns and the discs which comprise quick attachment means on said columns. In FIG. 1, the user 1 sits on a seat 2 and must, with his arms 3, maneuver an operating lever 4 from the bottom upwards according to

  the arrows F1 and F2 shown in FIG.

  Sitting and in starting position, as shown in Figure l, the user 1 must, to begin its movements, bend down to take the lever 4. It is difficult for him in this extreme position Pl to raise the lever 4 in the exercise position is in position P2. Indeed, the user will have the back too curved and it is not

  not the proper muscles that work.

  In this regard, the user can press the release lever 5 with his foot 6. Said release lever 5 by its cable 7 rotates the wheel 8 about a quarter of a turn. This wheel 8 mounted on the same axis 9, that the operating wheel 10 which is actuated by the cable 1l of the operating lever 4, thus relieves said operating lever 4 weights 12 which are arranged in load on the working column 13 Said operating lever 4 can be grasped easily and returned to the exercise position P2 as indicated by the arrow F3, also because of the cables

- 3 - 2561110

  or transmission chains 7 and 11, the action on the release lever 5 allows the operating lever 4 to automatically reassemble

in the P2 position.

  As shown in FIG. 3, when the operating lever 4 is in position P2, it can be operated efficiently as indicated.

by arrows F1 and F2.

  Figures 4, 5 and 6 describe an apparatus according to the invention o the user works in a supine position. It is this time with the arm 3 that the user 1 actuates the release lever 5. The user 1

  is lying on an operating board 14 which slides on axes 15.

  The user 1 is supported on the vertical base 16 with his feet 6 and then he makes his legs work which moves the board of maneuvering along the axes 15 and this by raising the weights in charge 12. The release lever 5 allows the user to position well before L5 to begin its exercise by temporarily disengaging the load 12 weights that are in charge. The user 1 can then easily move the board of maneuver to dispose of it adequately before

start exercising.

  FIG. 7 represents, schematically, how the release lever 5 acts by the cable 7 on the axis 9 of the wheels 8 and 10 so as to relieve the operating lever 4 of the load weights 12 by about a quarter of a turn. A return spring 17 returns the release lever 5 to its initial position. A stop 18 disposed on the wheel 10 allows the wheel e. clutch 8 turn for example a quarter turn before a pin 19 placed for this purpose abuts against said stop 18 and cause

  then rotating the operating wheel 10.

  Another improvement of the invention relates to the selection

  progressive 12 weights that can be taken care of or not.

  For this purpose, the working columns 13 comprise in their upper parts perforated discs 20, 21 which are threaded on said

working columns 13.

  Quick attachment means allow the disks 20, 21 to be maintained in this upper part. At will, the user can lower one or more disks 20, 21, along each working column 13. It can thus progressively measure the weight load 12 which can weigh for example 5 kilograms, while the disks 20, 21

  can weigh for example 0.250 kilograms.

  The weights 12 are loaded on the rope or chain 7 by a pin 22. The disks 20, 21 comprise a quick coupling means which may consist, for example, of a screw 23 transverse to the disk which presses via a spring on a ball that comes against the axis of the working column] .3 or preferably against one or more annular grooves 24 for example of flexible material provided for this purpose. The spring not shown in the figures is such that it allows the discs 21 to be held in the upper part of the columns 13 and a simple downward pressure makes it possible to slide the disc or discs

  who then come to load on the weights 12.
