GLIDER ASSEMBLY Filed May 8. 1963 Wallace h. Lucky INVENTOR.

United States Patent 3,220,772 GLIDER ASSEMBLY Wallace H. Lucky, Rte. 2, Box 220, Meridian, Miss. Filed May 8, 1963, Ser. No. 278,947 1 Claim. (Cl. 297-423) This invention or discovery relates to assemblies for regulating and controlling the forward-backward motion of articles of furniture utilizing a mechanical glider principle and particularly to glider type leg rest.

The primary object of this invention, when used in the construction of a leg rest, is to provide the leg rest with a motion counteractive to the push or pull of any extraneous source. This motion permits the leg rest to be used in combination with rocking chairs and especially the type of rocking chair in which the motion is controlled in part by springs, such as the platform rocker.

This invention may be manufactured from a variety of materials (wood or metal) and in different sizes and shapes, depending upon the size and shape of the leg rest to be constructed and the amount of tension desired in the motion of the finished product. The drawings illustrate the preferred form of my invention however, from the standpoint of simplicity in materials and design. These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of an exemplary embodiment in accordance with the invention;

FIGURE 2 is an exploded perspective view of the device; and

FIGURE 3 is a detail view in vertical transverse section, taken upon an enlarged scale substantially upon the plane indicated by the section line 3-3 of FIGURE 1 and showing the manner in which the body member is movably supported in the base member of the device.

In conventional types of leg rest there is no movement or movement is dependent entirely upon the user, I have combined the ordinary glider precept of suspending a body between two frames by means of arms, with a single tension spring. When the arms and spring are assembled as a unit, to be used in pairs in the construction of a leg rest, the spring acts as a lever pulling the suspended body (leg rest) forward or backward in opposition to force exerted by the user.

The glider frame or base member, designated as 1, is a piece of wood inch thick, 12 inches at base and inches high. The glider or body member designated as 2, is a piece of wood inch thick, 8 inches at base and 9 inches high. The glider is suspended on the glider frame by means of narrow metal straps or arms, designated as 3 and 4. The arms are cut from flat iron A2 inch thick, inch by 6% inches. inch holes are drilled on center /2 inch from either end. The arm is bent in a simple reverse curve or modification, beginning 1 /2 inches from either end so parallel lines drawn from the flat side of either end would be approximately 2 inches apart. The arms are mounted in pairs by means of appropriate size screw eyes with washers, 1% inches from base of glider, 3 inches either side of a center perpendicular line and 2 inches from top of glider frame, 3 inches either side of a center perpendicular line.

The spring, designated as 5, is a tension spring inch in diameter by 5 /2 inches long. Catches are opened on either end for simple installation and mounted by screw eyes to the lower center part of the glider frame, 2% inches from the base and attached to the upper center part of the glider, 1%, inches from the top. The foregoing mounting construction is duplicated at opposite sides of the device,

As illustrated, both the base and body members are boxlike structures having open upper ends. The body member has a cover or closure 6 removably secured to its upper end and overlying in vertically spaced relation the open upper end of the base member to close the space between the corresponding side walls of the base and body members.

Having thus described my invention or discovery, what I claim is as follows:

A glider leg rest comprising a base and a leg rest body movably mounted thereon, said base comprising a hollow box-like frame having side walls and an open top, said body comprising a hollow box-like structure of less width and length than said base and being received movably therein and having an open top with side walls spaced from the corresponding walls of said base and generally parallel thereto, means supporting said body for horizontal swinging movement in said base and comprising pairs of vertically extending laterally movable straps secured to said base and body and each pair of straps being disposed between a corresponding pair of side walls of said base and body respectively, each strap having its upper and lower ends respectively secured to mount said body for lateral swinging movement within said base, a plurality of spring means each disposed between and each secured to said body and base and resiliently opposing lateral swinging of said body and urging the latter toward a central and rest position in said base, a closure removably mounted upon said body and covering the open top thereof and overlying and covering in vertically spaced relation the top of said base.
