Paves, Jewish Home for the Aged, 11561 Petosky, Detroit, Mich. 48204 Filed Aug. 29, 1966, Ser. No. 575,693 6 Claims. (Cl. 272-57) ABSTRACT OF THE DISCLOSURE The exercise rocker disclosed herein relates to a fourway rocker having a substantially planar member. On the bottom side of this member in the preferred embodiment is attached a rib. This rib has a substantially parallel cen tral portion designed to permit smooth forward and rearward rocking movement. On each side of the central portion of the rib is a tapered rib portion, designed to permit smooth side to side rocking.
This invention relates to an exercise device and, more specifically, to an exercise rocker which an individual may place his feet upon and accomplish various exercise routines by moving the rocker in the prescribed manner.
As will become more clear hereinafter, the objects and features include the provision of an exercise rocker which may be utilized to exercise the legs and other body parts while standing, sitting or being bed ridden.
These and other objects and features of this invention may be attained in a preferred embodiment of the exercise rocker which includes a substantially planar member having oppositely facing bottom and top sides with a rib extending away from thebottom side and an arch support member disposed on the top side. The rib is configured so that an individual may place his feet upon the arch support and rock the exercise rocker in two different directions which are substantially transverse to one another. Such rocking movements may be accomplished by providing the rib with a' central portion which is substantially parallel to the planar member and is arcuate for allowing rocking motion in a first direction. The rib is also provided with tapered portions extending from each end of the central portion toward the planar member so that the planar member may be rocked from one tapered portion, to the central portion, and to the other tapered portion and vice versa, thus accomplishing a rocking motion in the other direction. The novel exercise rocker may, for example, be used by placing the rocker in front of a chair enabling the seated operator to rock his body forward, backward, left and right, thus giving a workout to all the muscles in his body.
Other objects and attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
FIGURE 1 is a plan view of a preferred embodiment of the instant invention and showing an operators feet in phantom;
FIGURE 2 is a view taken substantially along line 22 of FIGURE 1;
FIGURE 3 is a cross-sectional view taken substantially along line 3--3 of FIGURE 1; and
FIGURE 4 is a perspective view of the preferred embodiment illustrated in FIGURES 1 through 3.
Referring now to the drawings, wherein like numerals indicate like or corresponding parts throughout the several views, a preferred embodiment of the exercise rocker is generally shown at 10. The exercise rocker includes a planar member 12 having oppositely facing bottom and top sides which are indicated generally at 14 and 16 respectively. The exercise rocker 10 also includes a first 3,361,427 Patented Jan. 2, 1968 means, generally shown at 18, which extends from the bottom side 14 for allowing rocking movement in first and second substantially transverse directions upon engagement thereof with a surface, such as that illustrated at 20 in FIGURES 2 and 3. The exercise rocker 10 also includes second means, generally shown at 22, on the second side 16 for receiving and positioning an operators feet, such as those illustrated in phantom in FIGURES 1 and 3.
The first means 18 includes a rib 24 which extends substantially perpendicularly from the bottom side 14. The outward extremity of the rib 24 includes a central portion 26 which is substantially parallel to the bottom side 14. The rib 24 also includes a tapered portion 28 extending toward the bottom side 14 from each end of the central portion 26. The central portion 26 of the rib 24 is arcuate, as indicated at 30 in FIGURE 3, for allowing rocking movement thereabout in a first direction. The convex arcuate surface across the bottom edge of the central portion 26 of the rib 24 comprises a means for defining all rocking movement in the first direction. The rocking movement in the second direction may be accomplished by rocking the exercise rocker 10 from one tapered portion 28, to the central portion 26, and then to the other tapered portion 28, and vice versa.
The second means 22 includes an arch support member 32 disposed on the top side 16. The arch support member 32 is substantially parallel to the rib 24. The second means 22 also includes the heel tabs 34. The heel engaging tabs 34 are disposed in spaced relationship to the arch support member 32. The arch support member 32 has a pair of spaced recesses 36 for receiving the arches of the operators feet. Also disposed on the top surface 16 are the end plates 50.
The exercise rocker 10 also includes the reinforcing ribs 38 which extend outwardly from the bottom side 14 at each end of the rib 24. Each of the reinforcing ribs 38 is tapered at 40 from a point 42, which is adjacent the rib 24, toward the bottom side 14 to allow the rocking movement about the arcuate central portion 26 of the rib 24. In addition, the outward extremities of the reinforcing ribs 38 are arcuate, as indicated at 44, adjacent the ends of the tapered portions 28 of the rib 24.
The rocker 10 may be utilized for various bodily exercises. For example, to exercise the legs, the exercise rocker is positioned on a surface 20, such as a floor, with the long dimension or longitudinal axis (which is parallel to the rib 24 and the arch support 32) being parallel to the front of the operators body. The operator may then stand or sit in a chair and place his feet over the arch support 32, as indicated in FIGURES 1 and 3. The operator then alternately presses down with his toes and back with the heels to rock about the arcuate surface 30 of the central portion 26 of the rib 24.
In another exercise of the legs, the feet are positioned over the end plates and alternately pressed down, i.e., first the left foot is pressed downward and then the right foot is pressed downward, to rock the exercise rocker 10 in a second direction which is transverse to the first-described rocking movement so that the exercise rocker contacts the floor successively through one tapered portion 28, then through the central portion 26, and then through the other tapered portion 28, and vice versa. The rounded or arcuate portions 44 on the reinforcing ribs 28 will allow the degree of such rocking movement to be increased.
Another leg exercise which may be accomplished with this exercise rocker is a bicycling movement wherein the operator sits in a chair and places the exercise rocker 10 so that its longitudinal axis is perpendicular to the front of his body. The operator thereafter places his feet on the top surface 16 and alternately presses downward with his feet to rock the exercise rocker 10 about the arcuate surface 30 of the rib 24. In other words, the rocker is positioned so that the longitudinal axis is in the line of sight of the user whereby the exercise rocker can be pedaled as a bicycle.
As hereinbefore pointed out, these exercises and various other exercises may be accomplished while the operator is in the standing or sitting position. However, such exercises also may be accomplished by a bed ridden individual by placing the exercise rocker 10 in a vertical position against a suitable surface so that it may be manipulated by the feet While the individual is in the proneposition in the bed. Such an exercise is suitable for patients who have been bed ridden for some time. The rocker is placed against the headboard of the bed. In order to avoid scratching the headboard, a bath towel should be placed over the headboard. In addition, a piece of plywood or a thick magazine should be placed under the lower edge of the rocker which stands in a vertical position having its top side facing the bed ridden patient and its bottom side facing the headboard. The patient then operates the rocker backward, forward, left and right.
The invention has been described in an illustrative manner and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that Within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
