Abstract

The invention relates to a treadmill comprising a front cylinder (1), which is height-adjustable and rotationally mounted, a rear cylinder, which is rotationally mounted and a belt (3), which runs around the front cylinder (1) and the rear cylinder and whose external surface forms the running surface (31) of the treadmill. The treadmill has at least one strut (4) that can be extended, on which the front cylinder (1) can be mounted, at least by indirect means.

Description

" on tape"

The present invention relates to a treadmill with the following features:

The treadmill comprises a front roller that is rotatably mounted and vertically adjustable. The treadmill further comprises a rear roller is rotatably mounted. To the front and the rear roller is placed a belt whose outer surface forms a tread of the treadmill.

Such a treadmill is known for example from the standard DIN EN 957-6. The height adjustment of the front roller of the treadmill, it is possible that the running surface of the treadmill can be caused by setting various heights of the front roller different inclinations. It can be simulated so different slopes. The patent US 5,669,857 discloses a solution, such as the front roller of the treadmill can be height-adjustable set. The roller is arranged with its ends on the roll with a pivoting lever pivotable. The lever in turn is pivotally attached to a support. By pivoting the pivoting lever about its bearing on the supports the front roller can be pivoted upwards or downwards. Thus, the amount and the incline of the treadmill can be adjusted.

A disadvantage of the method disclosed in the patent design is that there is a relatively high space requirement for the arrangement of the pivot lever and the supports. A device as disclosed in the patent, has therefore a higher space than, for example, a treadmill having no height-adjustable front roller. Since such Treadmills are often used in the home, where sometimes not permanently installed, but are only set up for training, there is a need for compact treadmills in which the inclination of the running surface can be adjusted and which have only a small footprint.

The invention is therefore the task of proposing a treadmill, which is compact on the one has an adjustable inclination of the running surface, and on the other, and is therefore particularly suitable for home use.

This object is inventively achieved in that the treadmill has at least one strut which is extensible and at which the front roller is mounted at least indirectly.

According to the invention, the strut may be carried out at least two parts, wherein the first and the second part in the direction of the major axis of the strut are movable relative to each other. It can not be rotatable about the main axis of the strut, the first part, whereas the second part is rotatable about the main axis of the strut.

Advantageously, one of the parts has a bore with an internal thread, into which an externally threaded bolt Direction of the other part is screwed moved.

However, the strut may also be formed in three parts, the third part can be moved relative to the first and the second part in the direction of the major axis of the strut. The third part may be to have an externally threaded bolt, which is screwed movably in a bore of the first or second portion, wherein t he bore has an internal thread. Alternatively, the third part may have a bore with an internal thread into which a bolt of the first or second part is movable screwed, wherein the bolt has an external thread.

According to the invention, the first, the second or the third part may comprise a toothed pulley.

The treadmill may further comprise a motor, the output has a toothed disc which is connected via a toothed belt of the toothed disc of the strut. By implementing the rotation of the motor via the toothed wheel to the toothed belt and the toothed belt on the toothed disc of the strut, the parts of the strut can be respect to one another by being a part unscrewed from the other part or screwed into this part.

In an advantageous embodiment, the treadmill on two carriers, the rear roller is mounted on the front ends of the front roller and the rear ends thereof. The front ends of the support may further be supported on a front housing. In the front housing, a swivel, to be arranged parallel to the front roller extending bracket. This bracket itself can be supported on two of the struts according to the solution, so that the front roller is mounted on the carrier, the front housing and the bracket indirectly to the struts. An exemplary embodiment is described with reference to the drawing. it shows

Fig. 4 is a perspective view of the strut shown in FIG. 3,

Fig. 5 shows the brace according to the figures 3 and 4 in the extended state and

Fig. 6 is a perspective view of the strut of FIG. 5.

The treadmill illustrated in Figures 1 and 2 comprises a frame 20 which is supported on the floor 16th In this context, in turn, a front housing 8 is rotatably mounted. Further, a bracket 22 is fixed to the frame 20 is attached to the upper end of a panel 10 for display devices. a front handrail 1 1 is further attached to the board 10 degrees. From the panel 10 starting, to a side railing 12, which is also fastened with its other end on the frame 20 extends. Both the supports 22, as well as the railing 12 are bolted to the frame 20 by screws.

The treadmill further comprises a front roller 1, which is connected to carrier 7 with a rear roller. The front roller 1 is supported at its ends to front ends of carriers 7 rotatably. Similarly, a rear roller at the rear ends of the carrier 7 is supported. The mounting of the rear roller at the rear ends of the carrier 7 is protected by the rear roller covers 13 against contamination. Further, the roll covers prevent an operator or a third party intervenes in the rotating rear roller, and thus incur injury. Around the rear roller and the front roller 1 is placed a tape 3 whose in the illustration of FIGS upwardly facing outer surface of 1 and 2 forming the tread 31 of the treadmill. The top of the support 7 constitute side platforms 71, which have a non-slip surface.

In the region of the mounting of the front roller 1 to the brackets 7, the front roll 1 is also mounted to the front case. 8 In the housing 8, a bracket 9 is also pivotally mounted which extends substantially parallel to the front roller. 1 The bottom of the front housing 8, in the area of ​​the right and left ends of the bracket 9 to a respective recess. By these recesses a right and a left brace 4 is guided which is fixed with its one end pivotally mounted on a cross member of the frame 20 and with its other end to the bracket. 9 The attachment of the braces 4 to the bracket 9 is configured such that the struts 4 are mounted rotatably about its longitudinal axis to the bracket. 9

The configuration of the struts 4 will now be explained with reference to Figures 3 to. 6 Accordingly, a strut 4 has a perforated plate 41 which is fixedly connected to a lower part of the 42nd This lug 41 is used for pivotable mounting of the struts 4 on the transverse beam of the frame 20. The lower portion 42 of each strut 4 is designed as a sleeve whose internal bore has an internal thread. In the lower part 42 a middle part 43 is screwed. This has a circular cylindrical cross section and has an external thread corresponding to the internal thread of the lower portion 42nd At the upper end of the central portion 43, a collar 44 is provided, which projects beyond the external thread of the central part 43rd Provided that the central part is fully screwed into the lower part of 42 43, proposes the middle part 43 with the collar 44 at the upper edge of the lower part 42 forming the sleeve.
