CH683967A5 - Training dumbbell for firming human support and movement anatomy - Google Patents

Abstract

Two suspended weights (2) are connected to each other by a rigid connector (3) which is outside the weights axis (4) of the dumbbell (1). The connector is set far enough outside the dumbbell so that the user can move freely with it without the vertical line of the centre of gravity (6b) of the body staying on the centre of the weights axis (5).The connector is an open or closed frame in the shape of a circle or circular segments. Alternatively, the frame may be of two long parallel sections, with the suspended weights, each having rounded ends for connection to the other. There are two grips (7) provides on the frame.

description

The invention relates to a training dumbbell according to claim 1 for strengthening the human support and musculoskeletal system.

In the prior art for free weights, the barbell (competition or barbell) is known. Its characteristic: it connects two weight suspensions with a straight axis. As a result, when lifting the load, the exerciser is forced to position his body either in front of or behind this axis; in any case, however, the upper body carries out additional holding work in order to counteract the lever that arises - from the perpendicular of the body's center of gravity to the weight axis of the barbell. This additional load is unnecessary for therapeutic training as well as for discipline-specific high-performance training, and in some cases. counterproductive.

The present invention now connects the two weight suspensions by means of a rigid connecting element outside the weight axis of the barbell and outside the body's center of gravity, e.g. with a circular arch so that the trainee can grab the dumbbell and work with it. This enables the weight axis to pass through the body, so that regardless of the body position (upright or bent or in motion), the plumb line of the body's center of gravity is in the same axis as the plumb line of the weight axis. Now it is possible to carry out therapeutic and discipline-specific training exercises in the lifting area or in locomotion. In addition, the impulse required for this can be freely selected, which for the first time enables device-independent design of the movement rhythm. In addition to the isometric, isotonic and isokinetic strength training methods, the piyometric and stato-dynamic methods can also be used optimally.

The weight suspensions correspond to the standard size; the choice of the additional charge is free. The invention is described in more detail with reference to the following figures:

1a shows the illustration of a training dumbbell according to the invention

1b and 1c schematically show an application example (lifting training)

2a, 2b and 2c show different handle shapes and fastenings

In FIG. 1a, numeral 1 shows the training dumbbell according to the invention; number 2 means the two weight suspensions, number 3 a rigid connecting element, number 4 the axis of the weight suspensions (weight axis), number 5a the center of gravity of the training dumbbell and the plumb line (5b) and number 6a the center of gravity of the user and that Lot to it (6b). The numbers 7 mean the handles. The handles are preferably located slightly above the weight axis so that the training dumbbell “hangs” in a horizontal position.

1b and 1c schematically show an application example for lifting training (squat); The user stands on the stand (14) in the dumbbell and is therefore able to guide the plumb line of the weight axis of the dumbbell in the plumb line of its body center of gravity (numbers 5b / 6b) in order to achieve optimal power transmission.

In Fig. 2a, number 7 mean a handle parallel to the weight axis (4), number 9 a fixed connector perpendicular to the rigid connecting element (3), respectively. for weight suspension (2). This handle arrangement is particularly recommended in performance training with large weight loads, respectively. with explosive-dynamic movements, as it gives the user a firm and safe grip, just like with the competition dumbbell.

Fig. 2b shows with number 10 a handle that is perpendicular to the weight axis (4) or with a hinge joint (number 11) with the rigid connecting element (3), respectively. the weight suspension (2) is connected. The handle can be rotated from the vertical, preferably continuously, through an angle into the horizontal. As a result, the user can train the neck and shoulder girdle area in particular with an optimal hand position.

Fig. 2c shows with number 12 a freely movable handle, which by means of a ball joint (number 13), which is attached to the height of the weight axis (4) and with the rigid connecting element (3), respectively. the weight suspension (2) is connected. This handle arrangement is useful for therapeutic, low-threshold training, since the force vector from the shoulder joint can act directly on the weight axis without deflection and thus exclude malpositions in the area of the wrist.
