Balance base for rowing machine

A balance base having a longitudinal and lateral direction and suitable as a stationary stand on which a rowing machine can be supported in alignment with the longitudinal direction comprising:

• a first balance base component having a first upper frame portion with a form-fitting or force-fitting fixation that serves for securing rear feet of the rowing machine, and a first lower frame portion connected with the first upper frame portion by a single first spring element connected to both the first lower upper frame portion and the first lower frame portion, the first upper frame portion having first and second laterally opposed edges, the form-fitting or force-fitting fixation being disposed such that the rear feet of the rowing machine when secured are longitudinally aligned with the first spring element, wherein no element disposed between the upper frame portion of the first balance base component and the lower frame portion of the first balance base component other than the first spring element provides resilient restraint to the lateral tilting of the rowing machine on the first balance base component;
• a second balance base component spaced longitudinally from the first balance base component and having a second upper frame portion with a form-fitting or force-fitting fixation that serves for securing front feet of the rowing machine, and a second lower frame portion connected with the second upper frame portion by a single second spring element connected to both the second lower upper frame portion and the second lower frame portion, the second upper frame portion having first and second laterally opposed edges, the form-fitting or force-fitting fixation being disposed such that the front feet of the rowing machine when secured are longitudinally aligned with the second spring element, wherein no element disposed between the upper frame portion of the second balance base component and the lower frame portion of the second balance base component other than the second spring element provides resilient restraint to the lateral tilting of the rowing machine on the second balance base component;
• the first spring element being made of an elastic or viscoelastic material and being confined between the first upper frame portion and the first lower frame portion in a laterally centered position of the first balance base component, wherein a first continuous lateral space extends from the first spring element to the first laterally opposed edge of the first upper frame portion and longitudinally along the entire length of the first spring element and a second continuous lateral space extends from the first spring element to the second laterally opposed edge of the first upper frame portion and longitudinally along the entire length of the first spring element, the first spring element providing resilient restraint to lateral tilting of the rowing machine on the first balance base component;
• the second spring element being made of an elastic or viscoelastic material and being confined between the second upper frame portion and the second lower frame portion in a laterally centered position of the second balance base component, wherein a first continuous lateral space extends from the second spring element to the first laterally opposed edge of the second upper frame portion and longitudinally along the entire length of the second spring element and a second continuous lateral space extends from the second spring element to the second laterally opposed edge of the second upper frame portion and longitudinally along the entire length of the second spring element, the second spring element providing resilient restraint to lateral tilting of the rowing machine on the second balance base component.

A balance base having a longitudinal and lateral direction and suitable as a stationary stand on which a rowing machine can be supported in alignment with the longitudinal direction comprising:

• a first balance base component having an upper frame portion with a form-fitting or force-fitting fixation that serves for securing rear feet of the rowing machine, and a corresponding lower frame portion, the upper frame portion of the first balance base component having first and second laterally opposed edges;
• a second balance base component spaced longitudinally from the first balance base component and having an upper frame portion with a form-fitting or force-fitting fixation that serves for securing front feet of the rowing machine, and a corresponding lower frame portion, the upper frame portion of the second balance base component having first and second laterally opposed edges;
• the first balance base component having a laterally centered first spring element made of an elastic or viscoelastic material confined between the upper frame portion and the corresponding lower frame portion of the first balance base component in a laterally centered position of the first balance base component and connected to both the upper frame portion and the corresponding lower frame portion of the first balance base component, wherein a first continuous lateral space extends from the laterally centered first spring element to the first laterally opposed edge of the upper frame portion of the first balance base component and longitudinally along the entire length of the first spring element and a second continuous lateral space extends from the laterally centered first spring element to the second laterally opposed edge of the upper frame portion of the first balance base component and longitudinally along the entire length of the first spring element, the first spring element providing resilient restraint to lateral tilting of the rowing machine on the first balance base component, wherein no element disposed between the upper frame portion of the first balance base component and the lower frame portion of the first balance base component other than the laterally centered first spring element provides resilient restraint to the lateral tilting of the rowing machine on the first balance base component;
• and
• the second balance base component having a laterally centered second spring element made of an elastic or viscoelastic material confined between the upper frame portion and the corresponding lower frame portion of the second balance base component in a laterally centered position of the second balance base component and connected to both the upper frame portion and the corresponding lower frame portion of the second balance base component, wherein a first continuous lateral space extends from the laterally centered second spring element to the first laterally opposed edge of the upper frame portion of the second balance base component and longitudinally along the entire length of the second spring element and a second continuous lateral space extends from the laterally centered second spring element to the second laterally opposed edge of the upper frame portion of the second balance base component and longitudinally along the entire length of the second spring element, the second spring element providing resilient restraint to lateral tilting of the rowing machine on the second balance base component, wherein no element disposed between the upper frame portion of the second balance base component and the lower frame portion of the second balance base component other than the laterally centered second spring element provides resilient restraint to the lateral tilting of the rowing machine on the second balance base component.

A balance base on which a rowing machine can be mounted for physical training comprising:

• an upper frame with a front portion adapted for connection to a front part of the rowing machine, and a rear portion adapted for connection to a rear part of the rowing machine;
• a lower frame with a front portion disposed below the front portion of the upper frame and a rear portion disposed below the rear portion of the upper frame;
• a first spring element positioned between the front portion of the upper frame and the front portion of the lower frame in a laterally centered position and providing resilient restraint to lateral tilting of the rowing machine on the balance base;
• and
• a second spring element positioned between the rear portion of the upper frame and the rear portion of the lower frame in a laterally centered position, and providing resilient restraint to the lateral tilting of the rowing machine on the balance base;
• wherein the first spring element and the second spring element are each made from an elastic or viscoelastic material;
• and
• wherein no element disposed between the upper frame and the lower frame other than the first spring element and the second spring element provides resilient restraint to the lateral tilting of the rowing machine on the balance base.
