Definitions

  • This invention relates to a machine intended for muscular training, which comprises a seat carried by a stand, a back rest situated above the seat, as well as a main arm which is turnable around a main joint against the effect of a loading device.
  • a muscular training machine of the kind generally mentioned above is previously known by the Applicant's Swedish patent SE 9403228-1 (publication number no. 506 459).
  • Said machine is especially intended for training the stomach muscles of the user and comprises for this purpose a transverse arm connected to the turnable main arm, which transverse arm is actuable by the fact that the user bends the trunk forwards and applies the chest against the same.
  • Characteristic of the known machine is also that the seat and the back rest are stiffly united to each other and extend at an obtuse angle to each other, the back rest being longer than the seat and having a convexly arched contact surface for the back of the training person.
  • the known machine is very suitable for training the musculature of the stomach, but is not for purposeful training of the back and the musculature thereof.
  • a primary object of the invention is to provide a training machine by means of which users having different body sizes and different bodily constitutions as well as different back flexing patterns may practise the back musculature thereof while the loading device of the machine applies optimal resistance to the back during a back flexing cycle.
  • An additional object is to create a training machine, which during a back flexing movement permits a spinal rotation.
  • Yet an object of the invention is to create a training machine which during training of the back relieves the pressure on the vertebra column in respect of compressive stresses so as to achieve an optimum back extension.
  • Back training machines having back rests which are mounted on turnable arms and movable orbitally backwards and forwards, are previously known per se .
  • the back rest is mounted directly on the turnable arm and therefore compulsory movable in a genuine arc-shaped path around the main joint of the arm, i.e. without a possibility of moving radially in relation to this joint during the back flexing movements of the user.
  • the back training machine shown in the drawings comprises a stand in its entirety designated 1 and a seat 2 carried in a fixed point by the stand.
  • a loading device generally designated 3 is mounted, which advantageously (but not necessarily) may be of the type which includes a set of weights 4, which in a suitable, selectable number may be lifted via a hauling rope 5 which is laid over two upper pulley wheels 6, 6'.
  • the set of weights is guided by two guide bars 7.
  • the hauling rope 5 is at the end thereof distanced from the set of weights 4 connected to an elongate cam disk 8 and partially laid along the periphery thereof.
  • Said cam disk has a substantially oval basic shape and is rigidly connected to a shaft 9 located eccentric in relation to the disk (see fig 4).
  • said shaft 9 Via two mutually movable and lockable adjusting disks 10, 11, said shaft 9 is connected to a main arm 12, which on the side thereof turned from the adjusting disk 11 has a perpendicularly projecting, rotatably mounted shaft 13, which forms a main joint around which the main arm 12 is turnable.
  • an axially movable, spring-activated ratchpin (not visible) is mounted which may engage one of a plurality of tangentially spaced holes 15 in the adjusting disk 10.
  • a turnable lever 16 is arranged for manipulation of the ratchpin.
  • a back rest 17 is also included in addition to the seat 2. Against this back rest a portion of the back positioned between the shoulders and the waist of a user may be pressed. Characteristic of this back rest 17 is that the same is separated from the seat 2 and connected to the main arm 12, more precisely by being mounted on a cross boom 18 (see also fig 5 and 6) which extends perpendicularly to a rocker arm designated 19, which is connected to the main arm 12 via a secondary joint 20. In the preferred embodiment, the joint 20 is placed at the upper end of the main arm 12, and located approximately halfway between the back rest 17 and a front end of the rocker arm 19.
  • a damper weight 21 is arranged on the front end of the rocker arm, the weight of which balances the weight of the back rest and the cross boom in such a way that the rocker arm assumes approximately the inclined state according to fig 1.
  • the joint 20 compulsorily moves along a genuinely arc-shaped path.
  • the accompanying back rest 17 can, however, freely move radially outwards as well as inwards in relation to the arc-shaped path of motion of the joint.
  • the seat 2 formed by a supporting plate and a soft cushion extends in the direction obliquely forwards/downwards at a moderate angle of inclination to the horizontal plane.
  • a leg rest 22 is arranged against which the lower parts of the legs of the user are applicable.
  • this leg rest is composed of a supporting plate and a soft, upper cushion, but unlike the seat, the leg rest 22 extends in the direction obliquely backwards/downwards. Also the angle of inclination of the leg rest in relation to the horizontal plane is moderate.
  • the leg rest is fixedly attached to a post 23, which is telescopically displaceable in a box profile 24 and lockable in different positions by means of a locking screw 25 or the like.
  • the leg rest is adjustable at different levels.
  • a jib 26 extends, which at the front end thereof carries a foot rest 27, which is situated in front of as well as below the leg rest 22. against said foot rest 27, the user may, if required, apply a foot of one of the legs.
  • the seat 2 is in the area of the rear end thereof connected to an additional support 28, which has a limited height and extends at an obtuse angle to the seat.
  • an adjustable belt 29 is advantageously also associated by means of which the user may fix the seat part thereof in relation to the seat.
  • an adjusting mechanism in its entirety designated 30 is furthermore included for variable adjustment of the rear end position of the back rest 17.
  • This mechanism includes a sleeve 31 fixed on the stand 1 and oriented horizontally in which a bar 32 movable axially backwards and forwards is inserted.
  • the bar as well as the sleeve may in practice consist of box profiles having a quadrangular cross-section shape.
  • a number of mutually spaced-apart holes 33 are formed arranged to co-operate with a ratchpin (not visible) which is connected to a spring-loaded withdrawable knob 34.
  • the bar 32 has an end body 35 made of an elastic material, e.g.
  • a spring in the form of a gas spring 37 is connected, which always aims to bring the bar 32 in the backward direction in relation to the sleeve and against the effect of which the bar may, in a manual way, be drawn in the forward direction to a selected position in which the ratchpin of the knob 34 can be brought to engagement with a selected hole 33 in said series of holes (simply by the fact that the knob 34 is released when the ratchpin is right in front of the desired hole).
  • the rear end position of the backrest 17 may be moved in the backward direction relatively the stand when the bar 32 is moved forwards in relation to the sleeve 31 and vice versa.
  • the back rest 17 may advantageously be composed of a stiff supporting plate and a soft cushion.
  • the supporting plate is connected to the cross boom 18 via a centrally placed joint 38.
  • Mechanical springs 39 e.g. in the form of helical compression springs, on both sides of the joint 38 guarantee that the back rest in the unloaded state assumes a position parallel to the cross boom 18.
  • the back rest is turnable at a moderate angle to the cross boom, either towards the left, as is shown in fig 6, or towards the right.
  • the angle of deflection ⁇ between opposite turning positions for the back rest is about 20° (i.e. 10° towards the left, 10° towards the right).
  • this angle ⁇ may vary upwards as well as downwards from said value.
  • the back rest 17 is movable along an arc angle ⁇ which per se varies depending on the position of the rear end position, but which in the example according to fig 2 amounts to approx. 55°.
  • the arc angle may amount to approx. 35°.
  • the main arm 12 In the unloaded state of the machine according to fig 1, the main arm 12 is folded forwards, the back rest 17 assuming a front end position.
  • the set of weights 4 assumes a lower position in which the tension force in the rope 5 is moderate (or equals zero), the rope, however, holding the elongate cam disk 8 in a starting position pointing steeply upwards.
  • the torque arm between, on one hand, the point of connection of the hauling rope against the cam disk and, on the other hand, a conceived vertical plane through the pulley wheel 6' is comparatively short. This means that the force that is required in order to lift the set of weights by turning the cam disk in the direction downwards/backwards is moderate.
  • the back rest 17 is applied against the back of the user, more precisely at a suitable point somewhere between the lumbar and the shoulders as is shown in fig 2.
  • the user In the starting position of the machine according to fig 1, the user is sitting with his trunk and back bent forwardly.
  • the torque arm between the point of connection of the rope 5 to the cam disk 8 and a conceived vertical plane through the pulley wheel 6' is then rather small.
  • the back rest 17 offers only a moderate resistance to motion in the backward direction.
  • the back flexing movement of the user consists of straightening out the back from the forwardly bent state (back extension) while the back rest moves in the backward direction towards the rear end position according to fig 2.
  • the back rest may move radially outwards as well as inwards in relation to the arc path and in this way smoothly follow the back, irrespective of individual variations in the movement patterns of the individual user, as well as in the movement patterns of different users.
  • the backbone may at the same time be subjected to a so-called spinal rotation, more precisely by the fact that the back rest, via the joint 38, may be turned alternately towards the left and towards the right.
  • the following muscles of the back musculature participate in an advantageous way: iliocostalis lumborum, iliocostalis thoracis, iliocostalis cervicis, longissimus thoracis, longissimus cervicis, longissimus capitis, spinalis thoracis, spinalis cervicis and spinalis capitis.
  • the following muscles participate in particular: multifidus, semispinalis thoracis, seminspinalis cervicis, semispinalis capitis and rotatores.
  • interspinales intertransversarii
  • levatores costarum quadratus lumborum.
  • abdominal muscles of the body participate, viz . obliquus externus abdominis, obliquus internus abdominis and transversus abdominis.
  • the body movement is reversed, i.e. from a straightened back the user bends the back forwards in the direction of the starting position for the back rest.
  • the back rest is subjected to a force of the loading device, which means that the user has to put his weight firmly against the back rest end up to the frontal starting position thereof.
  • the above-mentioned muscles participate.
  • the pressure on the lower lumbar region of the user is relieved, since the special training position means that the flexion in this region may be decreased. Also the activities of muscles in thighs, calves, seat and hip may be reduced. This is something that ensures clear advantages as regards the relief of the vertebra column.
  • the two lower parts of the legs are normally pressed against the leg rest 22.
  • the foot of said leg can be applied to and rest against the foot rest 27, while the lower part of the leg in working order is applied against the leg rest 22, as is shown in fig 2.
  • fig 7 illustrates an alternative way of mounting the back rest 17.
  • a pivot pin 38' included in the joint in question is arranged in an elongate hole 40.
  • This elongate hole enables lateral displacement of the back rest during the turning movement in relation to the pivot pin, as is outlined by dash-dotted lines in fig 7.
