Definitions
- the present invention relates to an apparatus for performing physical exercises, especially exercises similar to those developed in the practice of rowing, of the type comprising a frame including a longitudinal central beam that can be placed substantially in horizontal position in service, a seat mounted sliding on said beam, support means for the feet of the user, who are linked to the beam towards its front end, a lever articulated provided on at least one side of the beam, and a resistant means which connects said lever to the frame to slow down the movement of the lever controlled by the user.
- each lever is articulated on the frame so as to be able pivot around a vertical or substantially vertical pivot axis.
- each lever moves in a plane horizontal or substantially horizontal when operated by the user of the device. Under these conditions, the device allows the user to carry out movements almost identical to those which would be carried out by handling the oars of a real boat to oars.
- the two levers simulating the oars have necessarily a certain length and as they extend roughly horizontally and transversely with respect to the median axis longitudinal of the central beam of the frame of the device, the cross built on the ends of which the two are articulated respectively levers must itself have a relatively large length. It As a result, the device has a relatively large size in width and that, in order to be easily stored or transported, the frame of the device must be made in a foldable form, which makes its more complicated and costly to manufacture and may adversely affect stability of the device.
- Such known devices have a space requirement width significantly smaller than that of the known device mentioned in the first place in which the levers are articulated so as to be able to pivot around a vertical or substantially vertical axis. In however, the movements it allows to perform are more distant of those that are actually performed by handling the oars of a real rowing boat.
- the present invention therefore aims to provide an apparatus of the above-mentioned genre, which allows both close to those performed by handling the oars of a real rowing boat, while having a space requirement in width relatively small.
- the apparatus according to the invention is characterized in that the pivot axis of the lever makes a predetermined angle, less than 90 °, with the longitudinal median axis of the said central beam longitudinal, so that the free end of the lever, provided a handle that can be grasped by the user, is located in or at immediate proximity to the vertical plane containing the median axis longitudinal of said beam, when the lever is pushed into its position extreme forward, and is moved away from said vertical plane when said lever is pulled into its extreme rear position.
- the apparatus according to the invention can include, like the apparatuses known, two articulated levers arranged respectively on the side and on the other side of the longitudinal central beam of the frame, a resistant means being associated with each articulated lever.
- the pivot axis of each of the two articulated levers then makes said predetermined angle with the axis longitudinal median of said central beam, and this so symmetrical with respect to said longitudinal median axis.
- the aforementioned predetermined angle can be between 82 ° and 86 °.
- the aforementioned predetermined angle may have a fixed value which is chosen so that when the two levers are pulled into their extreme rear position, the handles of the levers are spaced from each other by a distance corresponding to a value average shoulder widths of users.
- said predetermined angle may be approximately equal to 84 °.
- the frame of the apparatus may advantageously comprise, in addition, two crosspieces fixed in their middle to the longitudinal central beam, transversely thereto while being spread in the direction longitudinal.
- Each lever can then be articulated on the face upper of one of the two crosspieces, near one of its ends outside or at selectable locations along the crosspiece to allow the above adjustment according to the user morphology.
- That of the two crosspieces on which the two are articulated levers can have an arcuate shape in a horizontal plane.
- the pivot axis of each lever can be substantially perpendicular to the radius of the arc which is formed by the arched cross member and which passes through the location where the lever is articulated on said crosspiece arched.
- each of the two levers can be articulated on the frame, for example on the crosspiece arched above, by means of a two-degree articulation of freedom ; a first of the two degrees of freedom corresponds to said axis of pivoting which makes said predetermined angle with the median axis longitudinal of the longitudinal central beam; the second degree of freedom can be provided by a second horizontal pivot axis or substantially horizontal, which is perpendicular to the first axis of pivoting.
- Such an arrangement also allows adaptation of the device, more precisely an adaptation of the spacing of the lever handles at the width of the user's shoulders. This adaptation can be done automatically in operation if each lever is left free, in use, to pivot around said second axis of pivoting.
- said adaptation is done before each use of the device, for example at using a joint with two degrees of freedom including the second degree of freedom can be blocked, for example using as a second axis swivel a bolt-nut assembly with operating knob for tightening the bolt or nut.

- each yoke 19, 19b can be displaced along the lever 8 a, 8 b corresponding and immobilized in any desired position along thereof with a locking known means (not shown) to to adjust the force multiplier effect of the corresponding lever 8 a , 8 b , therefore in order to adjust the resistant force felt by the user of the device 1 when he actuates the levers 8 a and 8 b .
- the pivot axis 9 a , 9 b of each lever 8 a , 8 b makes a predefined angle ⁇ (FIG. 3) with the longitudinal median axis 20 of the beam 3.
- This angle ⁇ is chosen in such a way that the handles 11 a and 11 b of the levers 8 a and 8 b lie in the vertical median plane of the beam 3, as shown in the right part of FIG. 1, or close to this vertical median plane, as shown in FIG.

- Locking means for example means cooperating by elastic snap-fastening, can be provided respectively on the cylindrical tail 22 and in the sheath 25 to axially retain the tail 22 in the sheath 25 after it has been engaged therein, but while allowing the extraction of said rod out of said sheath, if necessary, by exerting a predefined axial traction on the corresponding yoke.
- the yokes 17 a and 17 b are closer to the longitudinal central axis 20 than the yokes 21 a and 21 b .
- the angle ⁇ can be adjustable.
- each of the two yokes 17 a and 17 b can be fixed to the cross-member 5 in a manner similar to that shown in FIG. 2 in connection with the yoke 21 a , so that they can pivot around the vertical axis of their respective tails 22.
- the cross-member 4 can be provided, in the region of each of its ends, with a series of pairs of holes 23, 24, each containing a sheath 25 , as in Figure 2.
- the value of the angle ⁇ can be set in the range of 82 ° to 86 °.
- each of the two yokes 21 a and 21 b could be secured to a slide which can slide in a slide fastened to the cross-member 4 or formed therein.

- the levers 8 a and 8 b free to pivot around the corresponding axis 28 a , the abovementioned adaptation can be done automatically and at any time during the use of the device.
- the adaptation can be made before each use, for each user, by providing a locking means making it possible to lock, in a releasable manner, the lever 8 a , 8 b in a desired angular position relative to clevis 27 a .
- the pivot axis 28 a can be constituted by a bolt and nut assembly, the bolt or the nut being provided with an operating button so that, by tightening the bolt or the nut with the using the operating button, the angular position of the lever 8 a , 8 b relative to the yoke 27 a can be fixed.

- the articulation of the levers (of the type 8 a , 8 b ) relative to the cross member is then carried out at a determined point of each of the end parts of the cross member and the adjustment of the angle ⁇ results from the positioning of the parts end of the crosspiece with respect to the central part of said crosspiece.
- This articulation can in particular be produced as provided for the device of FIG. 1 or the device of FIG. 4.
- the advantage of this variant is that, for the packaging of the device, there is less space since the crosspiece which carries the lever joints can be conditioned in the disassembled state, resulting in a smaller packaging size.
- the tubes used for the realization of the sleepers of the device can have a cross section any, in particular circular or square.
