However, in these known machines 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.

Embodiment Construction

[0014] 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. In 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.

[0015] 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). 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 projec...

Abstract

A machine intended for back muscular training includes a seat (2) carried by a stand, a back rest (17) situated above the seat, as well as a main arm (12) which is turnable around a main joint (13) against the effect of a loading device (3). The back rest (17) is spaced from the seat and connected to a part of the main arm (12) extending upwards from the main joint (13), more precisely via a rocker arm (19) turnable around a secondary joint (20) on the main arm, which rocker arm has a cross boom (18), extending at an angle to the same on which the back rest is mounted. In this way, the back rest (17) is movable between a front starting position and a rear end position in an orbital path along which the back rest-thanks to the mounting thereof on the rocker arm (19)-can move freely between different radial positions in relation to the main joint (13) depending on the individual back flexing movements of individual users.

Description

[0001] 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.PRIOR ART[0002] 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 pe...
