Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] The invention relates to a training apparatus, in particular an elliptical or cross trainer, with two pedals which are fitted on a respective pedal bar, front ends of the pedal bars being connected in an articulated manner to a respective pedal lever. The pedal levers are connected pivotably to a respective front bearing. [0002] Training apparatus of this kind are known, for example, from the utility model bearing the publication number DE 201 00 276 U1. Furthermore, training apparatus of this kind are produced and sold by various suppliers, including the Applicant. [0003] During training, the person using a training apparatus of the kind disclosed in the document with the publication number DE 201 00 267 U1 stands on the pedals, which are connected fixedly to the pedal bars. During training, the user's feet execute an approximately elliptical movement, for which reason the term elliptical trainer is also used for such apparatus. The ellipse is oriented such that the main radii of the ellipse extend substantially horizontally. The person using the training apparatus therefore has the impression of moving forward in one plane. For certain training programs, it is desirable if the user of the training apparatus is given the impression of moving uphill or downhill. Such an impression cannot be conveyed with the known training apparatus of the type mentioned at the outset. [0004] An object of the invention is to improve a training apparatus of the type mentioned at the outset in such a way that different degrees of difficulty can be set and the person using the apparatus can be given the sensation of moving uphill or downhill. SUMMARY OF THE INVENTION [0005] According to the invention, this object is achieved by the fact that the front bearings are fitted with height adjustability on a front part of a frame, referred to hereinafter as the frame front part. By means of a displacement of the bearing point of the pedal levers, the orientation of the ellipse along which the user's feet move can be changed. The ellipse can be inclined upward or downward in relation to a horizontal. An inclination of this kind gives the user the sensation of moving uphill or downhill. [0006] To set the height of the front bearings, the training apparatus can have special adjustment means or means of adjustment. These adjustment means can comprise a drive, which is preferably an electric motor. The adjustment then no longer has to be effected by muscle power, and instead can be assisted by the electric motor. [0007] The adjustment means preferably comprise conversion elements for converting a rotational movement into a linear movement. These elements can comprise a spindle and/or a nut, and the nut can be arranged rotatably on the spindle. [0008] Rear ends of the pedal bars of a training apparatus according to the invention are advantageously connected in an articulated manner to a respective pedal crank. These pedal cranks can be arranged rotatably about a common axis. [0009] Handles can also be fitted or formed onto the pedal cranks. [0010] In an advantageous embodiment of the training apparatus, the pedals can be mounted displaceably on the pedal bars. The pedal can then be connected in an articulated manner to a respective push bar, the push bars advantageously being connected in an articulated manner to a respective push bar crank. These push bar cranks can be arranged rotatably about the axis about which the pedal cranks are already able to rotate. [0011] The distances between the points of engagement of the push bars on the push bar cranks and the axis are advantageously adjustable. [0012] The pedal cranks and/or the push bar cranks may advantageously be entirely or partially formed by circular disks. [0013] The points of engagement of the pedal bars on the pedal cranks and if appropriate the points of engagement of the push bars on the push bar cranks lie preferably in a plane which also contains the axis about which the push bar cranks and the pedal cranks are able to rotate. BRIEF DESCRIPTION OF THE DRAWINGS [0014] An illustrative embodiment of a cross trainer according to the invention is depicted in detail in the drawings, in which [0015] FIG. 1 shows a side view of the cross trainer; [0016] FIG. 2 shows a plan view of the cross trainer; [0017] FIG. 3 shows a view from the rear; [0018] FIG. 4 shows a view from the front; and [0019] FIG. 5 shows a perspective illustration. DETAILED DESCRIPTION OF THE INVENTION [0020] The cross trainer illustrated in FIGS. 1 to 5 has a frame with a lower part 1a and a front part 1b. The frame is produced essentially by two hollow profiles arranged at a distance from each other. The hollow profiles are largely guided parallel to each other, in particular in the region of the front part 1b of the frame. In a rear region of the lower part 1a of the frame, the hollow profiles are angled, so that they lie directly adjacent to each other in this region.
