Abstract

A training device (1) essentially consists of two bars (2, 3) and two carriages (4, 5) with recesses for the bars (2, 3). The bars (2, 3) are laid on a flat surface and engaged in the recesses of both lowered down carriages (4, 5). A person can position himself on both carriages (4, 5) and move then towards or away from each other against a low friction force. Moving the carriages (4, 5) requires an expenditure of force which in turn causes the muscles to become stronger.

Description

TRIMMING DEVICE

description

The invention relates to a trimming device according to the preamble of claim 1.

Such trimming devices, which are also called exercise bikes, have been known for a long time. Most of these trimmers are relatively complex constructions with mechanical springs and / or counterweights. While some of these devices are designed to strengthen certain muscles - e.g. B. leg or arm muscles - are suitable, others claim to be able to vigorously muscle all or almost all muscles as universal devices.

A home training device is already known which serves to strengthen the muscles and to strengthen the blood circulation as well as the activity of the lungs and heart (DE-A-2 411 198). This home training device has a base plate with four parallel grooves, where a slide is guided through two grooves. The disadvantage here is that a relatively large-area base plate is provided.

A similar device in which two slides arranged in parallel run on two wheels and / or runners is also known (US Pat. No. 4,402,506). Elaborate rolling or sliding devices must be attached to the sled.

A sled that has wheels that roll over round bars is also provided in another known trimmer (FR-A-2 403 089).

Furthermore, an exercise device for movement therapy is known, the one Has frame on which a carriage is guided in a longitudinally displaceable manner (DE-A-2 518 907). The slide and frame are relatively large. For example, the length of the plate corresponds to the distance measured between the knees and the crown of an adult. Comparable devices are also described in U.S. Patent Nos. 4,149,713 and 5,147,266, respectively.

A similarly complex muscle training device, which has a sliding frame made of square or round tubular steel and is arranged to be displaceable on two sliding handles, is also known (DE-A-38 00035).

In another known trimmer for gymnastics, two sledges are provided which are guided through bars or U-rails (DE-GM 74 08 254). The slides here have rollers that can roll or slide on the bars or in the U-rails. In this trimming device, too, a complex base frame is provided, which has two crossbeams which are connected to the bars or U-

Rails are interconnected.

Two foot slides which can be moved in parallel on rails are also provided in another known exercise device, these foot sleds being coupled to one another by two cable pulls running over deflection rollers (DE-GM 84 30 293). A disadvantage of this exercise device is that a base plate must again be provided for guiding the foot sled. In addition, an upright boom is provided on this base plate, which is arranged on a deflecting roller over which a

Hand cable is pulled.

Furthermore, a trimming device with a rod and a flexible friction sleeve is also known, which is slidably mounted along the rod (EP-C-295 246). Here, the friction sleeve is gripped with the hands and moved back and forth along the rod along a frictional force. The rod has at one end a rigid T-piece with non-slip padded legs and a display device for the respective training performance, the training performance corresponding to the temperature generated due to the friction. A strengthening of the leg muscles cannot be achieved with this trimming device.

Finally, a training device is also known, which two rectangular has shaped guide frames, of which two frame parts each serve as guide rails (US Pat. No. 3,559,986). The wheels of a movable roller block roll on these guide rails. Each roller block carries a foot section which serves to receive a user's foot. The foot parts are rotatable about an axis relative to the roller stands to position the user's feet, e.g. B. in

Direction of the trestle or perpendicular to it. On their underside, the foot parts have grooves which are placed over plastic pipes, so that the foot parts can slide along the surface of the roller blocks.

The invention has for its object to provide a training device with which the body muscles can be strengthened and which is very simple.

This object is achieved in accordance with the features of patent claim 1.

The advantage achieved with the invention is, in particular, that a variety of physical exercises can be carried out with the help of a device that is very light, which strengthen the arm, buttocks, abdominal, chest and leg muscles.

Embodiments of the invention are shown in the drawing and are described in more detail below. Show it:

1 shows a top view of the trimming device 1 according to the invention. This trimmer 1 consists essentially of two rods 2, 3 and two slides 4, 5. Each of the two rods 2, 3 is provided with three supports 6, 7, 8 and 9, 10, 11, one of which is attached each end and one located in the middle of rod 2, 3. These supports 6 to 11 serve on the one hand to be able to place the rods 2, 3 on a flat surface and on the other hand to provide a stop for the

Slide 4, 5 to represent. The slides 4, 5 are each provided with two plain bearings, each of which has three plastic half bridges, which are shown in broken lines in FIG. 1 and with 12, 13, 14 and 15, 16, 17 and 18, respectively , 19, 20 and 21, 22, 23 are designated. The edges of the slides 4, 5 but not the supports 6 to 11 with the plastic half bridges 12 to 23.

The slides 4, 5 preferably have a width such that they can be encompassed by a human hand. Their dimensions are z. E.g .: width 9 cm, length 22 cm, height 2.5 cm. The rods 2, 3 have a diameter of approximately 2.2 cm and a length of approximately 90 cm. The direction of movement of the slides 4, 5 is indicated by two double arrows 24, 25. While the carriage 4 slides on the rods 2, 3 between the stops 6, 7 and 9, 10, the carriage 5 slides on the rods 2, 3 between the stops 7, 8 and 10, 11. The rods 2 , 3 can be designed as hollow tubes and have end caps 26, 27 at their ends.

2 shows the trimming device 1 again in a side view. It can be seen here that the rod 3 rests on the supports 9, 10, 11 and carries two slides 4, 5. The slides 4, 5 are cuboid and have recesses on their underside. The rods 2, 3 are round and the recesses in the slides 4, 5 are semicircular at least in some areas.

3a shows a section A - A through the carriage 5. This section shows the bearing 23, which consists of an annular groove 30 in the carriage 5 and a semi-ring-shaped plastic part 1. The plastic part 31 can be punched out of a plate and be flat. The semicircular shape shown in FIG. 3 a only takes on when it is pressed into the groove 30. The plastic part 31 is not yet assembled in the illustration in FIG. 3a. However, as indicated by an arrow 32, it is pressed into the groove 30. The groove 30 is defined by an inner circumference 33 and an outer circumference 34. An outer circumference 35 of the plastic part 31 corresponds to the inner circumference 33 of the groove 30. The inner circumference 36 of the plastic part 31 has a smaller radius than the outer circumference 34 of the groove 30.

3b shows the assembled state of the plastic part 31. It can be seen here that the plastic part 1 with its inner circumference 36 over the circumference 34 of the groove

30 stands out.

4 shows a section B - B parallel to section A - A, in which the support 11 can be seen. This support 11 has a pin 40 which is inserted through a hole 41 in the rod 3. The plastic part 31, which in turn is fitted into the slide 5, rests on the rod 3.

FIG. 5 shows an enlarged illustration of the right-hand area of FIG. 2, which is framed there by dashed lines and is designated by C. One can see the carriage 5 in a locked position, in which between the two plastic half bridges 22, 23 the support 11 is arranged. Instead of three plastic half bridges 21, 22, 23, only two plastic half bridges 21, 23 or 21, 22 or 22, 23 can also be provided.

The carriage 5 is locked in such a way that the support 11 in one

Cavity of the slide engages. Further details are described in connection with FIGS. 6 and 13.

FIG. 6 shows a view of the underside of a carriage 5. A plurality of horizontal webs 50 to 59 and a plurality of vertical webs 60 to 65 are arranged on this underside. The horizontal webs 50 to 59 have semicircular indentations 66 to 77, 90 to 97, which in the vertical direction have a recess 45 or 46 for receiving the rods 2, 3 z. B. form for transportation. In the horizontal direction between two webs 60, 61; 62, 63; 64, 65 semicircular recesses are provided, in which plastic half bridges 78, 79, 80 and 81, 82, 83 are located. They exist e.g. B. from high or ultra high molecular weight low pressure polyethylene and take up the rods 2, 3, which are preferably made of PVC, during operation. The half bridges arranged one behind the other correspond to bridges 15, 16, 17 and 21, 22, 23 in FIG. 1.

Locking supports 11, as shown in FIG. 5, can engage in the cavities that are formed between the half bridges 78, 79 and 79, 80.

FIG. 7 shows a section D - D through the carriage 5 shown in FIG. 6. Here, partial areas of the recesses 92, 66, 68, 70, 96, 72, 74 and 76 are shown in FIGS

Webs 51 to 58 can be seen as well as the plastic half bridges 80 and 83. The recesses formed by the plastic half bridges 78 to 80 and 81 to 83 are designated by 60 and 61.

A section E - E through the carriage 5 according to FIG. 6 is shown in FIG. 8. Vertical webs 60 to 65 are arranged on the top side 41 of this carriage 5, which webs are connected by the web 52 running perpendicularly thereto. The recesses 66, 67 are provided in the web 52. The plastic half bridges 78, 79, 80 are indicated by dashed lines.

In order to be able to accommodate the bars 2, 3 more easily in a simple packaging, The recesses 45, 46 are provided, which through the recesses 90, 92, 66, 68, 70, 96, 72, 74, 76, 94 and 91, 93, 67, 69, 71, 97, 73 lie one behind the other , 75, 77, 95 are formed.

An example of the use of the trimming device 1 is shown in FIG. 9.

The person 100, who particularly wants to strengthen his arm muscles, grasps the carriage 5 with the right hand 101 and the carriage 4 with the left hand 102. Now, he tries to slowly move both carriages 5, 4 towards each other. If this succeeds, she tries to slowly remove the slides 5, 4 from each other again. Since the slides 5, 4 slide very easily on the rods 2, 3, it is very exhausting to move the slides slowly in the direction of the arrows 24, 25. This strengthens the arm muscles. The slides 4, 5 can be moved up to the stops 8, 11 and 6, 9 outwards. The movement is limited internally by the stops 7 and 10.

FIG. 10 shows a physical exercise with which the leg muscles in particular can be strengthened. In this case, the person 100 tries with the feet 103, 104 to slowly move the two sleds 4, 5 towards or away from one another. The body weight of the person 100 is divided into a horizontal and a vertical component. The vertical component causes a frictional force, while the horizontal component is directed outwards and tries to remove the slides 4, 5 from one another. By moving the feet towards each other, the horizontal component is removed, and by overcoming the frictional force, the slides 4, 5 come together again.

With the physical exercise shown in Fig. 11, the muscles of the arms, legs, abdomen, chest and back are strengthened. Here, the slides 4, 5 are slowly moved towards and away from one another with the hands 101, 102 and the feet 103, 104. It is also possible e.g. B. to lock the carriage 4 and only keep the carriage 5 slidable. The carriage is then locked in the

Way, as shown in Fig. 5, i. H. the support 11 engages in a hollow chamber of the slide 4.

A movement limitation inwards by the removable stops 7, 10 can be omitted, so that it is possible to use the feet 103, 104 to slide the carriage 5 to move to slide 4.

Due to the high sliding ability between slide 4, 5 and rods 2, 3, which results from the fact that the rods 2, 3 z. B. made of PVC and the slide bearings 12 to 23 made of high and ultra high molecular low pressure polyethylene (PE-HMW, PE-UHMW), it is only possible to move the sled on the poles with muscle power.

The entire trimming device can be packed in a simple manner by placing the two slides one behind the other in the longitudinal direction and inserting the rods into the recesses 45, 46. The entire assembly is then packed in an elongated box. If the two rods 2, 3 can be divided into two halves, they can be disassembled in the middle and the four individual parts that are created can be placed in the recesses 45, 46 of the two slides 4, 5. The slides 4, 5 with the rod halves are then packed in a box, the

Volume is hardly larger than the volume of the two sledges.

FIG. 12 shows the device of FIG. 7 again, with an additional device which makes it possible to change the frictional force which acts between a carriage 4, 5 and the rods 2, 3. This frictional force is changed in that the plastic half bridges 78 to 80 or 81 to 83 are pressed more or less firmly against the rods 2, 3. For this purpose, for example, a screw 110 is screwed into the wall of the slide 5, which presses with its tip against the elastic plastic half bridge 83 and thus bends it inwards. As a result of this bending, which is indicated by the half-bridge part 111, a greater normal force acts on a rod inserted into the half-bridge. Since the frictional force is equal to the product of the normal force and the coefficient of friction, the more the screw 110 is screwed in, the more the frictional force increases.

However, a screw 110 is only easily accessible at the edge of the slide. If the contact pressure of a plastic half bridge is to be increased from the inside, then a screw is not very suitable as an adjusting means. In order to also be able to increase the contact pressure from an inner position, a block 112 is provided which is inserted into a recess 113. This block has an end part 114, a web part 115 and a pressure part 116. If it is pressed into the recess 113 in the direction of the arrow 117, the pressure part 116 presses on the elastic plastic half bridge 83. If the block 112 is not required because the frictional force is not to be changed, it can be stored in an adjacent chamber 118 .

13, the carriage 5 of FIG. 12 is shown in a view from below. The plastic half bridges 78 to 80 or 81 to 83 can be seen here again, which are, however, narrower than in the illustration in FIG. 12, so that the semicircular recesses 119 to 121 or 122 to 124 on which they rest. The blocks 112 are inserted into the recesses 118 and 125, respectively, so that one can see their end parts 114. You can also see the pressure parts 116, which press against the plastic half bridges 79 and 82. Opposite these pressure parts 116 are guide webs 126, 127 which engage in corresponding recesses in the reinforcing ribs of the slide 5.

In Fig. 14a a block 1 12 is shown on a larger scale than in Fig. 12. The pressure part 116 has two inclined surfaces 130, 131 and a vertical surface 132. The dashed lines 133, 134 indicate that the web part 115 is hollow.

This can be seen more clearly in FIG. 14 b, where the long walls of the web part 115 are formed by the dashed lines 135, 136 and 137, 138, while the short walls are formed by the dashed lines 133, 139 and 134 , 140 are formed.

FIG. 15 shows a section FF through the carriage 5 shown in FIG. 13. It can be seen here that the plastic half bridge 82 is arranged above the recess 123 and from the vertical surface 132 of the pressure part 116 on one side Page 141 is pressed inwards. The original position of the plastic half bridge 82, ie the position without the action of a force by the block 112, is identified by the dashed line 142. The pressure part 116 projects through an opening in a web 143 of the carriage 5, this opening being delimited by lateral guides 114 which serve as a stop for one end of the plastic half bridge 82. The other end 145 of this half bridge 82 abuts another stop 146. 16 shows a further variant of the invention, in which two separate slide rods 150, 151 and 152, 153 are assigned to a slide 4, 5. While the carriage 4 can slide back and forth on the rods 150, 151, the carriage 5 can slide on the rods 152, 153. The ends of the rods are provided with supports 154 to 157 or 158 to 161. One end of two rods 152, 153, which are assigned to a first carriage 5, is coupled to one end of two rods 150, 151, which are associated with a second carriage 4. Rods 162, 163 can be provided as coupling elements, which are inserted into the hollow rods 150 to 153. Through special measures, e.g. B. by using screw-in clamps 164 to 167, the

Bars 150 to 153 are brought into a fixed spatial assignment, d. H. it is prevented that these rods 150 to 153 loosely slide back and forth on the rods 162, 163. Instead of rods 162, 163, joints can also be provided, as will be described in connection with FIG. 18.

17 shows a further variant of the invention, in which instead of two separate rods 150, 151 or 152, 153 only one, but curved rod 170 or 171 is provided per slide 4, 5. Each of these curved rods 170 and 171 has a U-shape, the open ends of the rods 170, 171 lying opposite one another and being connected to one another by rods 172, 173. The advantage of the device according to FIG. 17 compared to the device according to FIG. 16 is that the guide webs for a carriage are already brought into the correct position by the one-piece construction. In addition, only two instead of four webs have to be transported.

Another variant of the invention is shown in FIG. 18. This variant differs from the exemplary embodiment in FIG. 17 in that the two rods 170, 171 are each rotated by 180 degrees and with their closed U-ends 180, 181 lie opposite one another. These U-ends are provided with supports 182 to 185, of which two 182, 183 and 184, 185 are pivotable relative to each other via a joint 186, 187. Here are the pivotable to each other

Bearings 182, 183 and 184, 187 each assigned a different U-shaped end. The two other supports 188, 189 and 190, 191 per rod 170, 171 are arranged at the open ends as in the exemplary embodiment in FIG. 16. If rigid rods are provided instead of joints 186, 187, the U-shaped rods 170, 171 can nevertheless be pivoted relative to one another because they can be rotated in the supports 182 to 185.
