SE503800C2 - Arrangement for variation of loads in strength training - Google Patents

Abstract

The arrangement has a carrier (2) via a shaft coupling coupled to an electric motor (1) manoeuvred by the person training to rotate clockwise and counterclockwise dependent upon whether the load is to increase or lessen. When an outgoing shaft on the electric motor is made to rotate clockwise a threaded wt. carrier is screwed down into the wt. magazine (4) and several weights. are screwed into the wt. carrier which increases the load. When the outgoing shaft on the electric motor rotates counterclockwise the wt. carrier is screwed upwards out of the wt. magazine and the load reduces. After the load is adjusted, the person training draws in a main wire (8) anchored in a wire force distributor (7) which distributes the force in a main wire to two wires applied to the uppermost wt. plate in the wt. magazine.

Description

15 20 25 30 35 40 45 503 800 K1 ..] E. Fi. In the above objects and further objects, the device according to the invention has the features stated in the claims.

The device according to the invention is thus essentially characterized in that, for weight magazines on durable and new exercise equipment, an electric motor is driven which drives a threaded bar down or up through threaded holes in weights, which means that a varying number of weights are screwed into the threaded bar and brought to follow with up and down during the training session.

Elrnotom is controlled from a place adjacent to the patient who trains, which means that the weight load can be varied quickly during the training, with the result that the rehabilitation effect increases by avoiding unwanted interruptions in training, which is the case if the patient has to change the weight load manually.

The invention will be described in more detail below by means of exemplary embodiments with reference to the accompanying drawings, in which true numeral designations in the various figures indicate corresponding parts.

Fig. 1 shows the device in parallel perspective with included components.

Fig. 2 shows the device in parallel perspective when changing the weight load.

Fig. 3 shows the device in parallel perspective during active training. 111.111 .. E.

Fig. 1 shows the device with included components such as electric motor (1), threaded weight catcher (2), runner (3), weight plates (4) with threaded center holes, wire connections (5) in the top weight plate, wires (6), wire power distributors (7) and main wires (8).

Electric motor (1) is anchored to runners (3) where the guide rods (9) run through.

The threaded weight catcher (2) is applied with the required shaft coupling to the rotating output shaft of the electric motor (1). When the electric motor (1) rotates, the threaded weight catcher (2) is also caused to rotate. Depending on the direction of rotation of the electric motor (1), the threaded weight catcher (2) is screwed into or out of the weight plates (4).

The operation of the electric motor (1) takes place in close proximity to the patient who is exercising, which means that the weight load can be changed quickly during the exercise.

Directly the weight plates (4) fold together, the training person can give a signal to the electric motor (1) which either lightens or increases the load.

Fig. 2 describes the procedure when the patient wishes to increase the load during the exercise. By means of a control signal which the patient himself activates, the electric motor (1) is caused to rotate clockwise, which means that the threaded weight catcher (2) is screwed down into the weight magazine (4) and further weight plates (4) are screwed to the threaded weight catcher (2). ). 10 15 20 25 30 35 40 45 b) 503 800 To enable a downward or upward movement of the threaded weight catcher (2), runners (3), where the electric motor (1) is anchored, must run after the guide rods (9).

This is made possible by the runner (3) being provided with two holes (10) having a diameter which slightly exceeds the diameter of the guide rods (9).

To reduce the weight load, the patient activates a control signal which causes the electric motor (1) to rotate counterclockwise, which means that the weight plates in the weight magazine (4) are unscrewed from the threaded weight catcher (2).

Fig. 3 shows the course of events during training when the person training sets the desired weight load, in this case four weight plates. When the training person pulls on the main cable (8), the force is distributed via the cable cradle distributor (7) to the cable connections (5) on the top weight plate (4). When the force in the main wires (8) exceeds the force of gravity in the four top weight plates, they are forced to fl surface upwards. The aisle weight catcher (2), with screwed-on weight plates, and electric motor (1) follow the upward movement by runners (3) running up the guide rods (9).

Fig. 3 also shows one of the threaded center holes (11) in the respective weight plate and that guide rods (9) run through the entire weight magazine (4).

The number and weight of the weight plates can of course vary from one exercise machine to another.

The embodiments described above can, of course, be varied by the person skilled in the art in many different ways within the scope of the inventive invention.

The field of application can also be extended to areas other than those described.

Claims (1)

1. 0 15 20 25 30 35 40 45 505 800 PATENT REQUIREMENTS Device for varying the load during strength training for optimizing the rehabilitation effect during training of injured muscles / joints in that the weight load, with a minimum of interruptions in the training, can be varied during the training and thus Avoid unwanted interruptions in training that delay rehabilitation, especially in strength and endurance training, characterized by the fact that permanent or new training equipment is provided with a weight magazine (4) with threaded holes (ll), in the center of each weight plate, where the thread shape corresponds to one weight catcher (2) which is connected via a shaft coupling to an electric motor (1) which is operated, by the person training, to rotate clockwise or counterclockwise depending on whether the load is to increase or decrease, due to when an output shaft on an electric motor ( 1) is rotated clockwise, a threaded weight handler (2) is screwed into a weight magazine (4) and your weights are screwed into weight picker (2) which increases the load and when the output shaft of the electric motor (1) rotates counterclockwise, the weight catcher (2) is unscrewed from the weight magazine (4) and the load decreases, so that after the set load the person training in a main cable (8) pulls is anchored in a wire crane distributor (7) which distributes the force in a main wire (8) to two wires (6) which are applied to the top weight plate in the weight magazine (4) with two wire connections (5), which means that when the force in the main wire (8) exceeds the force of gravity in the weight plates which are crushed in a threaded weight harness (2) for whose holes (10) have such a dimension that runners (3), with anchored electric motor (1), a weight catcher (2) and weights from weight magazine (4), can run after guide rods (9) and be moved in vertical direction, in order to whenever there is a need to change the load, by the person so m trainer can control the electric motor (1) without interrupting ongoing training, which means that unwanted interruptions in training are avoided, which in turn means that the effect of the rehabilitation increases.
