DETAILED DESCRIPTION

A first embodiment of the exercise apparatus 10 is shown in FIG. 1. The apparatus 10 comprises two vertical spaced apart sides 12 and 14 forming a support structure 16 therebetween having a padded seat portion 18 and a curved back support portion 19 opposing the seat portion. The entire apparatus 10 is designed to solidly rest on a horizontal surface such as a floor.

The opposite sides of the structure are vertical panels 12 and 14 to which are attached unique elastic member anchor structures 20 in accordance with the present disclosure. These anchor structures 20 each include a spring anchor bar assembly 22 and an anchor socket assembly 24. Each spring anchor bar assembly 22 fits within an anchor socket assembly 24 that is fastened to the side plate or panel 12 or 14 of the exercise apparatus 10. In FIG. 1, three separate spaced anchor socket assemblies 24 are shown. Similarly, although not shown in FIG. 1, there are an additional three socket assemblies 24 similarly positioned on the opposite side of the apparatus 10. The locations of the structures 20 on the panels 12 and 14 may be other than as shown in FIG. 1, as these positions are merely exemplary.

Each socket assembly 24 comprises a socket member 41 as shown in FIGS. 5 and 6 that has a tubular portion 27 and a central flange portion 29. The flange portion 29 forms a ring around the tubular portion 27. The tubular portion 27 has a central bore 46 therethrough and a threaded radial bore 47. The flange 29 has a plurality of equally spaced holes therethrough receiving socket head screws 44. An annular backing plate 42 has a complimentary set of holes therethrough receiving the free ends of the socket head screws 44 as shown in FIG. 5.

As shown in FIGS. 1 and 2, each of the side panels 12 and 14 has three holes through which a socket assembly 24 is fastened to the side panel 12 or 14 of the apparatus 10. The spring anchor bar assembly 22 is separately shown in FIG. 3. The anchor bar assembly 22 is adjustably secured in the socket assembly 24 as is shown in FIGS. 1 and 2. The spring anchor bar assembly 22 may be removed from socket assembly 24 and repositioned in a different socket assembly 24 as the user may desire, simply by lifting the spring plunger 43 from the threaded bore 47 and sliding out the spring bar yoke 31 from the bore 46 in the socket assembly 24.

The spring anchor bar assembly 22 comprises an “L” shaped solid spring bar arm 32, a spring bar tube 33 slidably disposed on the short leg 26 of the spring bar arm 32 and a spring bar yoke 31 which removably fits within the central bore 46 through the socket assembly 24. The spring bar yoke 31 has a plurality of radial holes 40 therethrough. Preferably there are 8 radial holes 40 so that the anchor bar assembly may be positioned at eight different 45 degree positions around the socket assembly 24. When the spring bar yoke 31 is inserted into the central bore 46 in the socket assembly 24 the plunger cap or hand retractable plunger 43 engages into one of the holes 40 to position the yoke 31 at any one of the eight radial positions on the yoke 31 corresponding to registry of the plunger 43 with one of the holes 40 in the yoke 31. The hand retractable plunger 43 is a spring loaded pin that has its outer sleeve threadably inserted into the radial bore 47 through one side of the socket 41.

The spring anchor bar arm 32 is an L-shaped member having a smooth cylindrical portion on the short leg 26 and a series of axially spaced holes or detents 39 in the long portion 29. The long portion 29 is inserted through the transverse bore 25 in the spring bar yoke 31. A threaded release pin knob 36 has a spring loaded ball pin end 37 that threadably fits within the end of the spring anchor bar yoke 31. The release type pop pin knob 36 is threaded into the yoke 31 such that the pin end 37 engages with one of the detents or holes 39 in the long portion 28 of the spring anchor bar arm 32. When the knob 36 is tightened, the pin end 37 securely fastens the long leg 28 of the L-shaped spring bar arm 32 at one of the axially spaced detent positions 39 formed in the long leg 28 of the arm 32.

The spring anchor bar tube 33 has a series of anchor clip spots or eyelets 38 formed along its length. This tube 33 is slidably disposed on the short leg 26 of the spring bar arm 32. The spring bar tube 33 is secured to the spring bar arm 32 via cap screw 35 and washer 34 so that the spring bar tube 33 is free to rotate about the spring bar arm 32. Thus a spring hooked or otherwise fastened to any one of the eyelets 38 may be rotated about the anchor 20 without binding.

As can best be seen in FIG. 1, the elongated elastic member, in this case a coiled spring 11, may be hooked to any one of the eyelets 38 on the spring bar tube so as to position the anchor point of the elastic member 11 at any of a variety of positions spaced from and around the socket assembly 24 on the apparatus 10.

This allows a user to sit on the chair portion 18, grasp the free end of the elastic member 11, and perform various exercises utilizing resistance provided by the elastic member with the spring anchor bar assembly 22 located in either an upper, a mid, or a lower socket assembly 24 in order to exercise different muscle groups. Alternatively, a user may stand facing toward or away from the curved back portion 19 of the apparatus 10 and perform different exercises with elastic resistance members 11 such as springs anchored at almost an infinitely variable number of positions on the apparatus 10 afforded by the various locations of the socket assemblies 24.

Another embodiment of the exercise apparatus in accordance with this invention is shown in FIG. 2. Here this is a differently modified Pilates step barrel 50 to which in which spring anchor bar structures 20, as in FIG. 1, are attached, one on each side of the barrel 50. This permits a user to either sit on the barrel portion or sit on the extendable platform portion and perform various exercises with the added resistance afforded by elastic members 11 attached to the anchor bar structures 20 as described above with reference to FIGS. 1, and 3-6.

While the apparatus has been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the disclosure need not be limited to the disclosed embodiments. For example, an alternative means for retaining the cylindrical yoke 31 in the central bore 46 may be other than a spring loaded pin 43. Any structure that releasably prevents the cylindrical yoke 31 from rotating may be utilized to perform this function. Such an alternative embodiment may include an internal wedging device within the yoke 31 that engages a portion of the tubular portion 27 to prevent yoke rotation. It is therefore intended to cover all such various modifications and similar arrangements included within the spirit and scope of the claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structures. The present disclosure includes any and all embodiments as defined by the following claims.
