HEALTH CHAIR CONSTRUCTION Filed April 23, 1952 Patented Mar. 30, 1954 UNITED STATES PATENT OFFICE 7 Claims.
This invention relates to an improved health chair construction of the type including a back rest and a supporting bed member for supporting the body in various exercising positions, as well as positions conducive to rest and relaxation.
In moving th body into positions which are known to induce relaxation and rest, it is Well known that desirable results are obtained by locating the feet in various raised positions with respect to the rest of the body.
The present invention aims to devise an im proved chair construction particularly directed to facilitating the location of the feet in any one of a number of raised positions while the remainder of the body is in a prone position. It is also an object of the invention to combine in a chair construction novel adjustability features for a body supporting element whereby a series of exercising positions may readily be assumed. Still another object of the invention is to devise a simple and easily operated adjustable chair structure which can be cheaply manufactured and conveniently assembled and used.
These and other objects and novel features will be more fully understood and appreciated from the following description of a preferred embodiment of the invention selected for purposes of illustration and shown in the accompanying drawings, in which:
Fig. l is a plan view showing the improved chair member of the invention;
Fig. 2 is a cross-section taken on the line 22 of Fig. 1;
Fig. 3 is a cross-section taken on the line 3--3 of Fig. 1; and
Fig. 4 is a cross-section taken on the line 4-4 of Fig. 1.
In the structure shown in the drawing, numeral 2 denotes a supporting bed member, preferably consisting of a flat rigid panel of wood or other desired material, arranged to provide a hard unyielding surface normally lying in a horizontal plane. The supporting bed member 2 is formed with a head portion 2a which is adapted to serve as a back rest, and a foot portion 2b, and is supported at two opposite sides by panels 4 and 6 which are of tapering shape, as suggested in Fig. 2.
A base section maintains the supporting bed member in a raised position, such as that shown in Fig. 2, and this base section includes a rectangular shaped frame or enclosure consisting of side walls 8 and I and end walls l2 and 14. These wall portions are solidly secured to one another like. It will be observed that the end wall 52 is of a lesser height than the end wall M, as viewed in Fig. 2.
At one side of the rectangular frame, and preferably supported on the upper edge of the end wall I4, is a shaft it which has pivotally sup ported at either end thereof the two side panels 4 and 6 of the supporting bed member. The shaft It also passes through two vertical frame pieces I 8 and 20 which carry rungs, as 22, 24 and 2t, occurring in spaced relation to comprise a ladder element. By means of this arrangement it will be seen that the supporting bed member 2 is free to pivot in a vertical direction about the shaft 15.
In accordance with the invention means are provided for allowing an operator, while reclining on the supporting bed member, to raise and lower the bed 2 and its head portion 2a by means of a pair of pivoted adjustment arms 23 and 39. These arms are solidly secured to a shaft 32 rotatably mounted through the side panels 5 and 6 at the points indicated in Fig. 2. The arms are formed at their ends with handle portions, as shown, and at opposite extremities of respective arms I have provided cam portions, as 34 and 36, one of which is more clearly shown in Fig. 2. These cam members 34 and 36 are adapted to engage against vertical supporting leg members 38 and 40 solidly secured to the side walls 8 and. ll] of the base section. It will thus be seen, therefore, that by placing or positioning the arms 28 and 30 in either a forward position, such as that shown in Fig. 2, or in a fully lowered position, such as that shown in Fig. 1, the supporting bed member will normally occur in a tru horizontally disposed position. However, the operator may, by rotating the arms through various intermediate positions, cause the head portion of the supporting bed member to be raised throughout an appreciable distance, thereby varying the angle of inclination at which the bed member is disposed. It will also be noted that with the arms in a position such as shownin dotted lines in Fig. 2, an operator may carry out the raising and lowering operation while resting on the bed member with th head portionZa supporting the upper portion of the body. In an alternative position the operator may slide forwardly and assume a completely prone position and then reach backwardly and move the arms upwardly from the position shown in Fig. 1. These two types of exercise require the use of various muscles which can be desirably strengthened and stimulated thereby.
by suitabl fastenings such as screws, nails, or the Cooperating with the head rest in carrying out either one of thes operations described is a pillow member indicated in the drawings by the numeral 42. The pillow member is pivotally supported between the vertical supports of the head portion 2a on a shaft 42a, as shown in Fig. 2. This member is of a triangular shape, as viewed in cross-section and shown in Fig. 2 of the drawings, the effect of which is to provide variation in the angle of inclination at which the head and shoulders of the operator may be supported. The two positions of the rotatable pillow member are clearly shown, one being in the full line crosssectional showing of Fig. 2 and the other being represented by the dotted line position indicated in Fig. 2.
It is pointed out that in order to maintain the supporting head portion 2a, as well as the bed member free to pivot with movement of the two arms and their cam portions, it is necessary to secure the two side panels together independently of the base section, and this is provided for by means of a cross piece 44 which is solidly secured between the ends of the side panels, and which'is shaped to snugly receive at the upper edge thereof the two arms 28 and 30 when they are in the lowered position shown in Fig. 1. If desired, the cross piece 44 may be notched out to form shoulders on which the arms 28 and 30 may rest.
Further cooperating with the pivoting supporting bed member and the back rest is the ladder element already described, including the spaced rungs 22, 24 and 26, which are best shown in Fig. 3. The location of the ladder element is chosen with reference to the position of the back rest and pillow member so that the operator, while lying on his back with his head supported on the pillow member 42, may engage the feet against the rungs and perform various desired exercises, or, the feet may be merely supported on any one of the rungs to provide a desired degree of elevation of the feet relative to the remainder of the body and head and thereby induce relaxation of the back and leg muscles.
It will be apparent that by adjusting the position of the head portion of the bed member, or by adjusting the position of the pillow member 42, a series of exercising positions may be assumed while the feet are bearing against or resting upon any one of the rungs of the ladder element. Therefore, a unique and novel apparatus is provided for using many different muscles in the body, as well as facilitating a wide range of positions of rest with the body inv an inclined position. The side panels 4 and 6 may also be formed with slots 50 to provide hand grips for holding the body while using the rungs.
While I have shown a preferred embodiment of the invention it should be understood that changes and modifications may be made in line with the scope of the appended claims.
Having thus described my invention, what I desire to claim as new is:
