Abstract

An improved lower extremity exercise device has a planar bed and support members which form a channel and storage chamber. An elongate support member is positioned below an edge of the bed and forms a shoulder. The elongate member includes vertical sockets and horizontal apertures. Tubular pegs are inserted in the sockets and apertures in sequences selected by the user. Elastic bands are looped around the pegs and portions of the body for the performance of exercises. The shoulder provides a proper heel-resting surface for certain exercises. A slidable bar is positioned in the channel and can be moved outwardly and secured at a pre-selected extension. The outward end of the bar is also engageable with elastic bands and allows additional exercises to be performed. The improved device is portable and provides storage for pegs and bands.

Claims

1. In a lower extremity exercise board device of the type for use with endless elastic bands including a planar bed member closely associating with a plurality of vertical sockets for receiving band engageable peg members, the improvement comprising:

support means associating with the undersurface of the bed member forming an open-ended channel and at least one storage chamber to a side of the channel, said support means including;

an elongate support member rigidly connected to the bed member to be supportively arranged at the undersurface of the bed member and extend outwardly of the bed member along one edge thereof and generally parallel to said channel, said support member having an upper horizontal surface including a plurality of spaced-apart vertical sockets having axes at generally right angles to said planar bed and an external vertical edge surface including horizontal spaced-apart apertures having axes at generally right angles to the socket axes, said upper horizontal surface forming a depressed shoulder with respect to the edge of said bed member;

a slidable bar means movably arranged within said channel and terminating at an outward end thereof in band-engageable means, the bar means being movable outward of said channel to position said outward end at a pre-selected distance from said bed member;

latching means associated with said slidable bar means capable of securing the bar means at pre-selected positions from the bed member;

a plurality of band engageable peg members insertably cooperative with said vertical sockets and horizontal apertures wherein peg members are sized to be vertically held upon insertion at said sockets, and horizontally held when inserted at said apertures, wherein said peg members are capable of being selectively insertable to provide for a variety of band arrangements for different exercises; and

,

securement means associated with said storage chamber means capable of removably storing peg members;

wherein said improved device provides for a removably looping engagement of endless elastic bands around said peg members and band-engageable means without mechanical fastening of bands, and wherein said peg members and slidable bar means enable the device to be selectively arranged for a wide variety of band orientations.

2. An improved exercise board device as in claim 1 including removable cushioned sleeve members capable of removably engaging around said peg members.

3. An improved exercise board device as in claim 1 wherein said bed member is generally rectangular in plan.

4. An improved exercise board device as in claim 3 wherein said elongate support member forms said shoulder with a long edge of the generally rectangular bed member.

5. An improved exercise board device as in claim 4 wherein said channel is generally centered between the long edges of the bed member and has opposite open ends below the shorter edges thereof.

6. An improved board device as in claim 5 wherein a cross member is arranged along a shorter edge of the bed member and extends upwardly therefrom forming a raised resting surface higher than the plane of said bed member.

7. An improved exercise board device as in claim 6 wherein said latching means comprises opposing ridged surfaces of the slidable bar means and cross member, said cross member ridged surface being arranged adjacent an open end of said channel, and said slidable bar means having said ridged upper surface for a major portion of its length, whereby upon experiencing a vertical force the bar means contacts the cross member and said ridged surfaces latchingly mate to thereby retain said slidable bar means to the undersurface of said cross member at a pre-selected distance from the bed member.

8. An improved exercise board as in claim 1 wherein said support means is adaptable for supporting said device on a generally planar surface, and having skid resistant means along undersurfaces thereof.

9. An improved exercise board device as in claim 1 wherein at least one said horizontal aperture extends through said elongate support member and a peg member is capable of being slidably held therein whereby to enable the peg member to be retracted inwardly of said vertical edge surface for a major portion of the length of the peg member.

10. An improved exercise board device as in claim 1 wherein the band-engageable means of said slidable bar means comprises a transverse member forming a T-shape.

11. An improved exercise band device as in claim 5 wherein a pair of slidable bar means are longitudinally arranged within said channel and being separately movable outwardly and inwardly from said opposite channel open ends.
