SHEET 2 0F 2 ADJUSTABLE PILLOW APPARATUS BACKGROUND OF THE INVENTION The present invention relates to pillows and especially to adjustable pillows having means for varying the shape or thickness of the pillow.

In the past a great variety of pillows have been suggested but pillows for sleeping are usually filled with material such as foam plastics, or rubber, or filled with dacron, down or similar materials. Inasmuch as different individuals require or prefer different size pillows for best sleeping comfort, pillows are frequently produced in different sizes and having different thicknesses for different individuals. Pillows also come in different degrees of firmness. A foam polystyrene pillow might for instance come in thicknesses of 4, 6 or 8 inches. However, difficulties arise when individuals are staying away from home such as in motels, hospitals or with other friends at which time pillows are provided which may not be suited to the individual, which can result in difficulty in sleeping and in cricks in the individual's neck.

It is accordingly one advantage of the present invention to provide an adjustable pillow which may be adjustable for different individuals to provide additional comfort.

In the past it has been taught to have compartmentalized pillows some of which employ inserts and inflatable center portions in order to change the consistency of the pillow and especially the firmness of the pillow. One prior U. S. Pat. No. 3,594,833, teaches a feather pillow employing a spring loaded inner chamber, and U. S. Pat. No. 3,411,164 teaches an inflatable center section in a pillow.

SUMMARY OF THE INVENTION An adjustable pillow is provided having a pillow frame having two end portions connected by an adjustable middle portion for expanding and contracting the length of the pillow frame. Two distinct 'pillow sections are connected to the pillow frame with one section connected to each end of the pillow frame and one section also having a connection to a portion of the middle portion of the pillow frame. The pillow sections each have angled engaging surface for engaging each other so that one slides on the other when the pillow frame is telescoped in or out to adjust the length and shape of the pillow frame. The pillow sections may be removably connected with snaps, or the like, to the pillow frame and the telescoping frame can be frictionally held in a plurality of positions or may be provided with a ratchettype latching system for holding it in any position desired. The frame may have handles in each end section for ease in adjusting the frame and pillow.

BRIEF DESCRIPTION OF THE DRAWINGS Other objects, features and advantages of the present invention will be apparent from the written description and the drawings in which:

FIG. 1 is a perspective view of an adjustable pillow in its expanded position; a 7

FIG. 2 is a perspective view of the pillow in accordance with FIG. 1 in its fully contracted position;

FIG. 3 is a perspective view with the frame removed from the pillow sections; and

FIG. 4 is a cutaway sectional view of a pillow frame in accordance with the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIGS. 1 and 2, an adjustable pillow is provided with a pair of pillow sections II and 12, each having an angled surface 13 and M and having a telescoping frame 15 connected to the bottom of the

pillow sections

11 and 12. Frame 15 has a handle 16 at each end thereof for gripping for moving pillow for making adjustments.

FIG. 2 illustrates the pillow in a fully retracted position having its greatest thickness and shortest length, while FIG. 1 has the pillow fully expanded, having its greatest length and the least thickness in the middle of the pillow. Thus an individual desiring to use the pillow can grip each handle 16 of the telescoping frame 15 and slide the handles 16 towards each other or away from each other to slide the

pillow sections

11 and 12 over each other to adjust the length and the thickness to his requirements. The

angled surfaces

13 and 14 provide a wedge-like action for the adjustment but it should be clear that other shaped surfaces could be utilized for adjusting the pillow in different manners without departing from the spirit and scope of the invention.

FIG. 3 more clearly shows the operation of the invention 10 having

pillow sections

11 and 12 with

angled surfaces

13 and 14 with the frame 15 removed. Telescoping frame 15 has a pair of

end portions

17 and 18 which slide towards or away from each other, each end portion having a handle portion 16 and each

section

17 and 18 having snap attachments 20 which coincide with the location of the snap attachments 21 on the

pillow sections

11 and 12 so that the frame may be snapped to the pillow sections. The end section 118 has an elongated member 21 which telescopes in and out of a section 22 attached to end section 17. Section 22 has a pair of side members 23 and bifurcated separating member 24 for providing an opening for elongated member 21 to slide in and out of. End member 17 is formed with the section 24 thereon and has the top and bottom members 23 attached to 24 by adhesive or in any manner desired. The top section 23 has a pair of snaps 25 attached thereto for attachment to snap sections 26 located on the pillow 111 for engaging the opposite end of the pillow II from the snaps 29. Thus the

snaps

29 and 26 on the pillows Ill and 12 may be attached to the frame 15

snap sections

20 and 25 to secure the pillow sections to the frame. This invention is not limited to snaps for attaching the frame to the pillows, inasmuch as other attachments, such as Velcro, can be utilized without departing from the scope of the invention. The frame 15 may be telescoped by gripping the handle 16 and moving them towards each other or away from each' other by telescoping member 21 in the elongated hollow section 22 to the desired position. It should be observed that by having the one telescoping section 22 frictionally engage the telescoping section 21 the frame will hold its position by the frictional engagement.

it is contemplated that a ratchet mechanism utilizing a spring dog can be utilized for providing additional retaining force and this embodiment is illustrated in FIG. 4. FIG. 4 has the

end sections

17 and 18 having handles 16 and the

snap prtions

25 and 20 attached thereto. A sliding member 30 is similar to the telescoping section 21 except for the ratchet teeth 31 are formed in one side thereof. The telescoping section 32 is similar to the telescoping section 22 of FIG. 3 except that a ratchet spring 33 is provided to engage the ratchet teeth 31 so that sliding the telescoping member 30 in the telescoping section 32 will allow the spring dog 33 to slide in the ratchet teeth 31 and will hold the telescoping sections at any desired position. A protruding stop 34 is also illustrated in this view which operates in connection with a protruding member 35 located on the telescoping frame member 30 so that member 35 will engage the protruding stop 34 in telescoping section 32 to prevent the separation of the telescoping sections. The telescoping frame illustrated in FIG. 3 may also be provided with stop members 34 and 3S.

lt should be clear at this point that an adjustable pillow has been provided which may be easily adjusted for different individuals and which adjusts the length of the pillow as well as the thickness by having a distinct pillow section sliding over a second distinct pillow section. However, it should also be realized that this invention is not to be construed as limited to the particular forms disclosed herein since these are to be regarded as illustrative rather than restrictive.

I claim:

1. An adjustable pillow comprising in combination:

a pillow frame having two end portions movably con- 1 each engaging surface of each pillow section being slidable on the other pillow section when said pillow frame is adjusted whereby the shape of said pillow can be adjusted by adjusting said pillow frame;
