This invention relates to an exercise equipment, and more particularly to an exercise equipment with column structure.
In general, various auxiliary aids and assistive devices are often needed in yoga, aerobics exercise or balance exercise to stretch exerciser's muscles. Among the auxiliary aids and assistive devices, rods and column structure are most widely used, as shown in
The technical problem the present invention wants to solve is that when the column body and buffer foam are conjugated together, the buffer foam is either glued on the column body or squeezed onto the column body, so that there is no structure to position of the buffer foam and the column body, which will easily cause sliding and misalignment when the column body is rolling.
The present invention provides an exercise equipment may include a column body, which is hollow and has a plurality of engaging ribs protruding at outer surface thereof. A cover layer covers outer surface of the column body, and the cover layer can be made by plastic injection or high-density foam. Inner surface of the cover layer has recessed slots corresponding to the engaging ribs, so that the cover layer can tightly cover the outer surface of the column body through the engagement of the engaging ribs and the recessed slots to avoid sliding and misalignment between the column body and the cover layer. Furthermore, in addition to the engaging ribs, the outer surface of the column body also has a plurality of auxiliary protruding ribs and auxiliary recessed slots to form the structure of the exercise equipment in the present invention.
Comparing with the prior arts, the present invention is advantageous because (i) the column body has a plurality of engaging ribs protruding at outer surface thereof and the cover layer covers outer surface of the column body. Inner surface of the cover layer has recessed slots corresponding to the engaging ribs, so that the cover layer can tightly cover the outer surface of the column body through the engagement of the engaging ribs and the recessed slots to avoid sliding and misalignment between the column body and the cover layer; and (ii) one end of the column body has the connecting portion to connect different column bodies to increase the variability thereof.
The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.
All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention. The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.
In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:
Referring to
One lateral side of the column body (10) has a U-shaped handle (30), which has two through holes (31) on both sides thereof corresponding to the engaging ribs (11) of the column body (10), so that the handle (30) can be conjugated on the engaging ribs (11) at the outer surface of the column body (10) through the through holes (31). Furthermore, the handle (30) can be restricted between the column body (10) and the cover layer (20).
Referring to
According to the embodiments discussed above, the present invention has the following advantages because: (i) the column body (10) has a plurality of engaging ribs (11) protruding at outer surface thereof and the cover layer (20) covers outer surface of the column body (10). Inner surface of the cover layer (20) has recessed slots (21) corresponding to the engaging ribs (11), so that the cover layer (20) can tightly cover the outer surface of the column body (10) through the engagement of the engaging ribs (11) and the recessed slots (21) to avoid sliding and misalignment between the column body (10) and the cover layer (20); and (ii) one end of the column body (10) has the connecting portion (14) to connect different column bodies (10) to increase the variability thereof.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
