Exercise device

Abstract

The invention relates to an exercise device ( 1 ), especially for balance training, comprising a base plate ( 2 ) having a first side ( 3 ) and a second side ( 4 ) opposing the first side. The first side ( 3 ) is embodied as a standing surface ( 5 ) on which the person training is to stand, and the second side ( 4 ) of the base plate ( 2 ) is rotatably or tiltably connected to a mounting plate ( 6 ). In order to enable the user to train with the use of axes, on an appliance with a simple and compact structure, the base plate ( 2 ) is connected to the mounting plate ( 6 ) by means of at least one first spring element and one second spring element ( 7, 8 ), the first and second spring elements ( 7, 8 ) being arranged preferably essentially symmetrically around a central point ( 11 ) of the base plate ( 2 ).

1 .- 13 . (canceled) 
     
     
         14 . An exercise device, comprising:
 a mounting plate;   a base plate having a center, a first side and an opposing second side, wherein the first side of the base plate is constructed as a standing surface for an exercising person and the second side of the base plate is rotatably or tiltably, or both;   at least one first and at least one second spring element arranged around the center of the base plate and connecting the base plate to the mounting plate;   at least one first rolling element arranged on the second side of the base plate substantially near the center of the base plate and having a first rolling direction;   a second rolling element having a second rolling direction oriented essentially normal with respect to the first rolling direction, wherein the first and the second rolling element are constructed as a single piece and together form a cross-shaped convex rolling element; and   a convex center element arranged at an intersection point of the cross-shaped convex rolling element.   
     
     
         15 . The exercise device of  claim 14 , wherein the exercise device supports balance training of a subject. 
     
     
         16 . The exercise device of  claim 14 , wherein the at least one first and second spring element are arranged substantially symmetrically about the center. 
     
     
         17 . The exercise device of  claim 14 , wherein the convex center element is formed as a partial sphere. 
     
     
         18 . The exercise device of  claim 14 , further comprising a convex receptacle arranged in the mounting plate. 
     
     
         19 . The exercise device of  claim 18 , wherein the convex receptacle has a shape of a rolling curve of the convex center element. 
     
     
         20 . The exercise device of  claim 14 , wherein the base plate is connected to the mounting plate with more than two spring elements. 
     
     
         21 . The exercise device of  claim 20 , wherein the base plate is connected to the mounting plate with four spring elements. 
     
     
         22 . The exercise device of  claim 20 , wherein the first rolling direction extends between two adjacent spring elements. 
     
     
         23 . The exercise device of  claim 20 , wherein the first rolling direction extends symmetrically between two adjacent spring elements. 
     
     
         24 . The exercise device of  claim 14 , wherein an excursion of at least one of the first rolling element and the second element is adjustable substantially normal with respect to the second side. 
     
     
         25 . The exercise device of  claim 24 , further comprising at least one first threaded drive for adjusting the excursion. 
     
     
         26 . The exercise device of  claim 14 , wherein at least one of the first and second spring element is constructed as a coil spring. 
     
     
         27 . The exercise device of  claim 14 , wherein at least one of the first and second spring element comprises a rubber-elastic material. 
     
     
         28 . The exercise device of  claim 27 , wherein the rubber-elastic material is an elastomer. 
     
     
         29 . The exercise device of  claim 14 , wherein at least one of the first and second spring elements is configured to be pre-biased in at least one region.
