Strength training - Device for three-dimensional train execution

The invention relates to a strength training device according to the preamble of claim 1 as embodiment 1, or an embodiment 2 according to the preamble of claim 2.

In the following, an exemplary embodiment of the state of the art is explained in more detail with reference to the drawings.

Show it:

Known pulling devices have a simple design of a bundle of ropes (1) that is pulled upwards by a pulling rope (2) that is guided over deflection rollers (3) and (4) over a rotatably mounted roller block (5) that has two deflection rollers (6) and (7).

In these traction devices, the line of symmetry (8) of the rotation axis (9) of the roller block (5) is parallel and at a distance from the line of symmetry of the traction cable (2).

In these traction devices, the traction cable (2) is guided over the deflection pulley (4) without friction, as long as the traction is introduced in such a way that the pulley block (5) does not rotate to the left or right beyond a certain angle (11).

As soon as a certain angle (11) is exceeded, the traction cable (2) is pulled diagonally over the pulley (4). The line of symmetry (10) of the traction cable (2) no longer runs parallel to the line of symmetry (8) of the axis of rotation (9) of the pulley block (5).

In order to compensate for this disadvantage and to keep the angular deviation (12) within limits, the pulley block (5) would have to be placed further away from the deflection pulley (4) so that the angular deviation (12) of the symmetry line (8) of the rotation axis (9) to the symmetry line (10) of the traction cable (2) is kept within limits.

The invention is therefore based on the object of eliminating this disadvantage and making it possible for the traction cable (2) to be guided straight over the deflection pulley (4) in every direction of pulling movement, even if the pulley block (5) is placed directly on the deflection pulley (4).

The features of claim 1 and 2 serve to solve this problem.

In the following, the inventive step for improving the traction device is shown as embodiment 1 with reference to the drawings.

Fig. 7 the passage of the traction cable through the bearing unit of the rotatable

mounted roller block.

The inventive step as embodiment 1 is based on the fact that the traction cable (2) is guided through the line of symmetry (8) of the bearing unit (13) and the deflection rollers (4), (6) and (7) are arranged such that the traction cable is guided in a straight line through the bearing unit (13).

The straight passage of the traction cable (2) through the bearing unit (13) is ensured if the distance of the center line (14) of the deflection roller (4) and the distance of the center line (15) of the deflection roller (6) or (7) to the line of symmetry (8) of the bearing unit (13) corresponds to the central rolling radius (16), or (17) and (18).

In the embodiment 1, the bearing unit (13) is designed in such a way that a deep groove ball bearing (20) is inserted into the roller block (5). The roller block (5) is inserted into the roller block holder (19) and the bushing (22) pressed into the roller block holder (19) is pressed into the deep groove ball bearing (20). The washer (21) ensures axial relief of the ball bearing (20).

So that cables can also be inserted into the roller block (5) from below, the bearing unit (13) is installed on both sides in the roller block (5).

In the following, with reference to the drawings, the inventive step for implementing embodiment 1 as a rubber pull device in a training room constructed with profile material is shown as embodiment 2.

-A-

The inventive step as embodiment 2 is based on the fact that the individual components of the strength training device are arranged in a three-dimensional space constructed with profile bars. This profile arrangement enables the pull to be carried out from above, below or to the side, from any body position. In embodiment 2, profile bars are drawn which are arranged as positions (23) and (25) vertically on the outside, as position (24) horizontally above, as position (43) below between the lying cushions (59) to (60), as position (44) to the side of the back cushion (67) and as position (45) horizontally above the back cushion (67).

Example 2 shows a pulley unit (32) with a pulley block holder (35) which is attached to the profile (25) with a star grip (42) and a hammer nut (29). The advantage of this attachment is that the pulley unit (32) is movable, and thus the pre-tension of the rubber rope can be varied and trained with different forces.

The deflection roller unit (32) consists of the roller block holder (35) with the fastening elements (42) and (29), the roller block (40) with two deflection rollers (37) and (39) fixed in the roller block by cylindrical pins (38).
The axial rotation of the roller block (40) in the roller block holder (35) is made possible by the bearing bushes (36) pressed into the roller block holder (35). The bearing of the roller block (40) and the bearing bushes (36) is designed as a clearance fit so that the roller block (40) can rotate easily. As in the example 1 as a cable pull (2), here the rubber pull (31) is guided straight through the bearing bushes (36).

The corner pulley units are mounted in the profile connection corners with a roller block (26), two pulleys (27) and (28) and the profile fastening elements hammer nut (29) and screw (30).

Another pulley unit is shown in the roller block (46) with the pulleys (49) and (50), which are fixed in the roller block with the cylindrical pin (51) and the profile fastening elements hammer nut (47) and screw (48).

In contrast to the movable deflection roller unit (32), a movement of the roller block (46) enables a threefold change in the pre-tension of the elastic band (31) caused by the threefold deflection of the elastic band (31) with the same displacement path.

So that the elastic band (31) is guided straight through the bearing bush (36) without touching the bearing bush (36) in this arrangement, the bearing bushes (36) in the deflection roller unit (32) are offset from the center by half the distance (34). The distance (34) corresponds exactly to the center roller distance (33) of the roller block (26) or the center roller distance (52) of the roller block holder (46).

In addition, the straight passage of the elastic band (31) through the bearing bushes (36) is ensured by the distance of the center line of the deflection rollers (27) and (28) in the roller block (26), or the distance of the center line of the deflection rollers (49) and (50) in the roller block (46), to the line of symmetry of the bearing bushes (36) corresponding to the central rolling radius of the elastic band (31) over the deflection rollers (27) and (28) of the corner bearing block (26), or the deflection rollers (49) and (50) of the roller block (46).

Two identical pulley units (32) are required for each elastic band device, which are attached rotated by 180 degrees to each other to ensure that the elastic band (31) runs straight through the bearing bushes (36).

The elastic band (31) is guided through a rubber buffer (57) as it exits the pulley unit (32) and is secured in a hook (56). Pull loops (53) are clipped into these hooks (56) in such a way that when pulling by hand, both loops (54) and (55) are clipped into the hook (56), and when pulling by foot, the pull loop (53) is passed through the loop (54) and only the loop (55) is clipped into the hook (56).

To ensure that the pull loop (53) cannot tighten when attached as a foot loop, the loops (54) and (55) are made of elastic. This material prevents the pull loop (53) from sliding in the loop (54) and thus from tightening the pull loop (53).

The rubber buffer (57) provides strain relief and thus noise insulation when the hook (56) hits the pulley unit (32) during training.
