Patented Aug. 28, 1951 UNITED STATES PATENT OFFICE PLATFORM FOR RECLININ G CHAIRS Philip Mednick, Brooklyn, N..Y. Application March 29, 1949, Serial No. 84,17 7

This invention relates to reclining chairs and constitutes a platform for same, either to be made a part of said chairs, or to be attached as a separate unit.

The device is constructed so as to be adjustable to the width of a chair, and will readily adjust itself to any irregularities in the floor.

It is also possible to combine the said device with a chair having a pair of front legs.

The device is simple of construction, effective in operation, and inexpensive and easy to attach to a chair.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a perspective elevational view of my device.

Figure 2 is a view similar to Figure 1, showing a detail construction of same.

Figure 3 is another detail view; while Figure 4 is a somewhat perspective elevational view, showing my device in part attached to a chair provided only with front legs.

Referring more particularly to the drawing, the numeral Ill indicates a pair of base rails, block members II, are at one end hingedly attached to the latter, as shown especially at I2 in Figure 2. Plates I3 are secured to the opposite ends of said block members and upon the inner sides thereof.

Angle irons I4 are pivotally attached to the plates I3 by means of bolts I5; while metal strips I6 are pivoted at one end to the angle irons I4 as shown at I8 and at the other end pivotally connected to the base rails II] by means of bolts I1 and plates I9 mounted upon said base rails.

The block members I I are formed with cavities 20; springs 2| are mounted in the latter and abut with their upper ends the angle irons I4. Said angle irons are formed with holes 22 through which screws or bolts, not shown, are inserted when attaching said angle irons to the rails or sides of the bottom of a chair.

In order to adjust the width of the platform, blocks 23 have been fixedly secured to the base rails I0; cross bars 24 are inserted in corresponding holes 25 in said blocks, as each bar has one end fixedly attached to a block and the opposite end loosely inserted and subsequently clamped in one Of the holes 25, as illustrated especially in 3 Claims. (01. -56) Figure 3, where a block 23 is shown with a hole 25, a split opening 26 and a clamping bolt 29 with wing-screw 30 threaded thereon. The said bars are so fastened that when one of these is adjustable at one end the other bar is adjustable at the other end.

In Figure 4 is shown part of a chair with front legs 3|; said chair has its bottom rails or seat 32 connected to the angle irons I4 of the platform, by means of bolts 33 inserted through the holes 22.

When leaning back in a chair attached to the platform, as shown herein, the block members I I will tilt, as shown in Figure 2, while simultaneously the seat of the chair attached to the angle irons I 4 will follow this movement, cushioned at the same time by the springs 2|, and prevented from tilting over too far by means of the strips I6.

It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not, therefore, wish to limit myself to the exact construction shown and described herein.

What I claim as new, and desire to secure by Letters Patent of the United States, is:

1. A platform for reclining chairs, comprising a pair of base rails, block members hingedly attached to the latter and adapted for tilting in a rearward direction, said block members being attached to the base rails a short distance from one end of these, plates secured to said block members at their ends remote from said attachment, and upon the inner sides of the block members, angle irons pivotally attached to said plates, second plates mounted upon the inner sides of the base rails, strips having one end riveted to the angle irons and the other end pivotally attached to said second plates, the block members being formed with grooves therein, springs mounted in said grooves and abutting said angle irons, whereby to cushion the impact between the latter and the block members, second block members secured to the inner sides of the base rails, and means connecting said latter block members, whereby to adjust the width of the platform; said angle irons being made to engage the seat of a chair.

2. A platform for reclining chairs, comprising a pair of base rails, block members hingedly attached to the latter and adapted for tilting in a rearward direction, said block members being attached to the base rails a short distance from one end of these, plates secured to said block members at their ends remote from said attachment, and upon the inner sides of the block members, angle irons pivotally attached to said plates, second Plates mounted upon the inner sides of the base rails, strips having one end riveted to the angle irons and the other end pivotally attached to said second plates, the block members being formed with grooves therein, springs mounted in said grooves and abutting said angle irons, whereby to cushion the impact between the latter and the block members, second block members secured to the inner sides of the base rails and being formed with horizontal bores therein, cross bars mounted in said bores and having alternately one end solidly secured to a block member and the other end adjustably attached to the opposite block member.

3. In a device, as claimed in claim 2, and each 4 of the second block members being at one end formed with a slot adjacent said bore, and having a vertical orifice in one end thereof and intercepting said slot, and a pin mounted in said orifice, whereby to secure the bar to the said block member in an adjusted position.

PHILIP MEDNICK.
