United States Patent REMOVABLE COVER LAWN CHAIR Carl Straub, Nebraska City, Nebr. Application August 28, 1953, Serial No. 377,033
3 Claims. (Cl. 155-54) The present invention relates to chairs of the type normally used out of doors.
It is an object of this invention to provide a lawn chair, the framework of which will not deteriorate when exposed to the weather.
It is another object of this invention to provide an outdoor chair with back and bottom portions which are easily removable for cleaning and storing since out-of-door chairs readily become soiled and unfit to sit upon.
It is a further object to provide a lawn chair fulfilling the above-stated objectives, yet retaining a measure of the comfort of more expensive chairs due to the inherent resiliency of this construction.
Yet a further object is to provide a chair as described which has arms while retaining its simplicity and economy of construction.
Yet another object of the invention is to provide a device for the purpose described which is sturdy and durable in construction, reliable and efiicient in operation, and relatively simple and inexpensive to manufacture, assemble and utilize.
Other and further objects and advantages of the present invention will be apparent from the following detailed description and claims and are illustrated in the accompanying drawings which, by way of illustration, show the principles of the invention and a mode in which I have contemplated applying those principles.
Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.
In the drawings:
Figure 1 is a perspective view of the lawn chair of this invention. The back and bottom portions together with the framework therefor are shown by dotted lines in the downward position they assume when the back and bottom cover portion is being removed for cleaning or storing.
Figure 2 is a partial top plan view of a forward corner of the chairs seat at one place where the two sections of the framework are hinged together. The seat cover and the adjacent framework is broken away and shown in section.
Figure 3 is a sectional view taken on lines 33 of the seat corner shown in Figure 2.
Figure 4 is a perspective view of a modification of the present invention wherein the arm rests are eliminated and the framework is substantially of one piece construction.
Figure 5 is a perspective view of a refinement of the chair shown in Figure 4.
Referring to the drawings for a more particular descrlption, the framework of the lawn chair is preferably made of stainless steel or aluminum tubing, although other material of other formations would also be suitable.
As shown in Figure 1, the chairs framework is in two Sections; the pedestal, armrest, and back support frame 'ice portion 12 and the seat and back frame portion 14.
The frame portion 12 is preferably formed of one continuous piece of metal tubing, wherein all corners are well-rounded to retain the strength of the tubing.
Located at the forward side of the chair, two spaced apart, parallel upright leg sections 16 are formed integrally at their lower ends with forward ends of the sides of a C-shaped pedestal base section 18, which latter is horizontal and rests upon the ground.
The middle portion of the C-shaped base section 18 is transversely disposed with respect to the chair proper and is located at the rear of the chair.
Spaced vertically above the base 18 another C-shaped frame section 20 is located having a horizontal, transversely disposed back support part 22 and two horizontal arm rest parts 24, which latter each extend forwardly and at their forward ends curve downwardly into the described upright legs 16.
A transversely disposed brace 26, welded or otherwise secured at each end to the middle of the legs 16, extends horizontally therebetween.
The seat and back frame portion 14 is of one-piece construction and, as best shown in Figure 3, the two ends 28 of the horizontal side parts 29 have been flattened from their original tubular shape and are downwardly bent into a circle around each end of the described horizontal brace 26 to form hinges which latter are located closely spaced inwardly from the upright legs 16 and allow the frame 14 to pivot forwardly in a vertical plane.
From the two widely spaced apart ends 28, the sides 29 of the frame portion 14 extend horizontally rearward and there curve up to join back-side parts 31 which are connected by a transverse horizontal back portion 32. The two parallel side parts 31 of the frame- 14 rest against the inside of the back support member 22 of the frame 12.
A slip cover 35 for the chair is preferably made of canvas or similar material in a sack formation. The sack formation includes a flat upper side 36 normally closely spaced apart from a flat lower side 38, the spacing being approximately the thickness of the frame section 14.
The slip cover 35 has a flap 42 which protrudes outwardly from the upper side 36 of the cover 35 and is in use folded down, across, and under the brace 26.
Inwardly from the folded end of the flap 42, and transversely disposed thereacross is a row of spaced apart, female snap rivet buttons 46 secured through the canvas. A transverse row of similarly spaced apart male snap rivet buttons 48 are secured in the forward edge of the lower side of the cover 35.
When installed for use the sack-like cover 35 is pulled over the seat and back frame 14 when the latter is pivoted forwardly as shown in Figure 1, and the flap 42 is then wrapped around the horizontal brace 26.
The snap buttons 46 and 48 are aligned with each otherand snapped together to removably secure the cover 35 to the frame 14.
The chair modification shown in Figure 4 is also provided with two spaced apart upright parallel legs 52 curving backward at their lower ends into a C-shaped base 54, which latter is identical with the base 18 of Figure 1.
The upper ends of the legs 52 curve to a horizontal direction. These horizontal portions 54 extend backwardly and then extend upright as at 56 where they are integrally met by a transverse horizontal section 58. The foregoing described frame is of one piece construction.
A horizontal transverse tube 60 is welded or otherwise suitably secured between the upper ends of the legs 52, whereby a sack-like slip cover 64, provided with a flap 66 at the open end thereof and matching rows of snap rivet buttons 68 thereon, is pulled over the top of the Patented Nov. 20, 1956 chair 50 and is snapped around the said horizontal tube 6.0.
In the use of this chair for outdoor purposes and as shown in Figure 1, the slip cover 40 may be easily removed by pivoting the seat and back frame 14 to a partially inverted forward position and the snap buttons 46 and 48 are then released, whereby the cover 40 may be slipped oif for washing or storage.
The slip cover 64 of the modified chair 50 may also be easily removed in a similar manner.
The construction of both chairs is such that when a person rests his full weight upon the covers the tubular frame portions will spring lightly toward each other for allowing the give that is necessary for comfort.
In Figure the C-shaped base membenkthe upright leg members 52 and the horizontal portion 54 are the same as shown in Figure .4. The upright portions 70 corresponding with the portions 56 of Figure 4 curve backwardly and extend into the horizontal back support 58 through carefully rounded corner portions 72.
Horizontal transverse tube member shown at 60 in Figure 4 is modified as follows: a tube member 74 is of slightly curved formation and connects with the uprights 52 at a position below the point where the uprights 52 bend and continue into the horizontal portions 54.
The curvature of the tube 74 allows for additional comfort since a straight rigid bar does not contact the limbs of a sitter. The curvature of the portion 70 and the round corner 72 provide the same comfort at the top of the back of the chair since the sitter does not lean directly against a horizontal unyielding bar.
The cover 35 is of the same formation shown in the previously described figures and its method of removal is the same as for the modification shown in Figure 4.
The same flap 42 curves around the rod 74 and fastens by means of the same snap button formation 46 and 48 shown in detail in Figure 3.
As described, the construction of the chairs will not be subject to deterioration from weather or hard usage whereby their period of useful service will be appreciably lengthened.
From the foregoing description, it is thought to be obvious that a lawn chair constructed in accordance with my invention is particularly well adapted for use, by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification Without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.
