Definitions

  • the invention relates to a weight training apparatus with a load arm mounted on a frame and pivotable upwardly and rearwardly from a lower end position through a horizontal position, to which a weight is adjustably mounted in the longitudinal direction, a force application member to which a trainer or compressive forces are exercisable, and transmission members that transmit these forces as torque to the load arm.
  • Such training devices are known in many forms. They compete with electric, hydraulic and spring devices, some of which offer greater comfort at significantly higher costs, but are especially preferred with attachable weight plates by many coaches and exercisers.
  • the above-mentioned devices with a during an exercise through the horizontal position up and down pivoting load arm especially the perceived as pleasant property is estimated that a large stroke is available and in the load-load diagram when lifting the weight of his lowest position, the applied force is initially relatively small, steadily increasing towards the horizontal position of the load arm and steadily decreases again on further lifting in the highest position.
  • This sinusoidal rising and falling load curve which can also be modified by changing the extreme positions of the Lastarms, in many exercises corresponds to the physiological conditions that the body and the members in the central region of a movement amplitude can apply a greater force than in the range of end positions , d. H. at the strongest flexion or extension.
  • the second disadvantage of the known devices of the type mentioned above is in so far as the first together, as the end of an exercise with the weight in the lower end position lowering load arm on the transmission members, the force-engaging member in the region of an extreme position entrains.
  • the next person exercising on the device must therefore enter the device in a strongly bent or stretched position, if necessary make certain adjustments to the device in this posture and then start from this position.
  • the invention has for its object to provide a training device of the type mentioned above, while maintaining the advantageous properties of a pivotable through the horizontal position load arm with simple means much more comfortable than conventional such exercise equipment.
  • a Kraftsport - training device with the characterizing features of claim 1, wherein the load arm above the lower end position in the horizontal or up to about 20 ° inclined position by a locking member directly or indirectly supported and in the supported position the Weight is displaceable by means of an electric motor or manual drive and a transmission with self-locking.
  • the locking and support of the load arm in the horizontal position provides in a load arm with motor or manually adjustable weight the double advantage that are given at the same time for getting into the unit and for changing the load optimal conditions.
  • the horizontal position In a device which is operated with a pivotable by the horizontal position up and down the load arm is, regardless of a multiple possible setting of the upper and lower end position, the horizontal position, if not exactly in the middle, then at least in middle range of the set movement amplitude. Accordingly, the exerciser can very comfortably get in, make any necessary adjustments to adapt to his body measurements and start from about half-stretched out position with the exercise.
  • the settings usually also include a change in the maximum load torque, d. H. a shift of the weight along the load arm. Since this is held at the beginning of the exercise in a horizontal position, the adjustment needs no power to lift the weight.
  • the electric motor and its switching device can be designed for minimal dimensions and amperage, or alternatively, the manual drive can make do with a single turn of a hand wheel or a crank, because the applied torque only just has to be sufficient to reduce the friction in the drive train and in the guidance of the weight to overcome.
  • the locking member which in a simple embodiment effective between the load arm and the frame, by a trainee controllable pawl drive between a locking position and a release position displaceable or pivotable pawl, in the Locking position is locked against movement in the release position until a for Upward pivoting of the load arm sufficient tensile or compressive force acts on the power drive member. This ensures that at the moment when the locking member releases the load arm, the trainee applies the necessary force so as not to drop the load arm with the weight.
  • the above-mentioned lock which prevents inadvertent or too early retraction of the pawl from the locked position, can be achieved in an expedient development of the invention by a latch attached to the pawl or -aussparung, in the locked position with the frame or the load arm in positive engagement is and after actuation of the pawl drive only at the beginning of the upward pivoting of the load arm disengaged.
  • the pawl is a preloaded by a contact spring to the locking position, linearly displaceably guided locking pin and the controllable pawl drive acting against the engagement spring Bowden cable or solenoid.
  • a contact spring to the locking position, linearly displaceably guided locking pin and the controllable pawl drive acting against the engagement spring Bowden cable or solenoid.
  • the controllable pawl drive acting against the engagement spring Bowden cable or solenoid.
  • the arrangement may also be reversed such that the pawl is loaded by a spring in the direction of the release position and by a controllable by the trainees pressure or tension member, z. B. an electromagnet or Bowden cable to move into the locked position.
  • the safety is preferably further promoted by the fact that the load arm can be supported by the locking member or further locking members in more than one position.
  • the pawl mounted on the load arm and arranged with several arranged on a frame part on a circular arc abutments, z. B. in the form of holes to be engaged.
  • the pawl mounted on the load arm is to be brought into engagement with a plurality of holes arranged in a straight row on a pivotally mounted frame part. In both cases, when a deployment spring is used immediately after a trainee leaves the force, and he no longer actuates the Bowden cable or electromagnetic drive of the pawl, it engages one of the existing holes before the weight has reached a higher fall speed.
  • the series of holes allows a simple and optionally variable attachment of end stops to the upper and lower limits of the movement amplitude, z. B. in exercises of patients in rehabilitation. It is understood that in kinematic reversal the pawl or other locking member also mounted on a part of the frame and with one or more abutments, for. B. holes, in a connected to the load arm part is to be engaged.

About a concentric on the pivot axis of the Kraftarms 16 rotatably mounted on the frame 10 shaft 20 of the power arm 16 is rotatably connected to a load arm 22 which carries a 24 consisting of circular discs weight. Since the weight 24 is on the same side of a vertical central longitudinal plane through the common pivot axis of the power arm 16 and the load arm 22, when the handle 18 is pushed up, the weight 24 mounted on the load arm 22 is pivoted upwards.
