INVALID WALKER Filed May 4, 1953 Snnentor JOHN G. L csu:
an LAWRENCE N. ROBINSON MXM attorney INVALID WALKER Application May 4, 1953, Serial No. 352,616 6 Claims. (Cl. 155-22) This invention relates to devices for supporting invalids and more particularly to a combined seat and walker or a combined seat and crutches.
' In valid walkers of previous design and of the type with which we are familiar, folding the walker for storage or transportation is difficult. In some designs of previous walkers, the lateral bracing members were removed to allow the various sections of the walker to be stacked for storage and transportation. In other types of foldable walkers and invalid supports, the folding mechanism was complicated in construction and had certain other disadvantages.
It is, accordingly, an object of this invention to overcome the above and other defects in prior invalid walker designs and it is more particularly an object of our invention to provide a laterally foldable invalid walker which is simple in construction, economical in manufacture and cost, rigid and durable in construction, and
comfortable to the occupant and light in weight.
Another object of our invention is to provide a laterally foldable seat and walker combination which is light in weight and easily portable.
Another object of the invention is to provide a novel means of attaching a seatto a walker.
Another object of our invention is to provide a novel folding means for a walker.
Another object of this invention is to provide a novel combination of crutches in a laterally foldable walker.
With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims, it being understood that aired States Patent changes may be made in the form, size, proportions, and
minor details of construction without departing from the spirit or sacrificing any of the advantages of the position; and
Fig. 4 is a detailed view of another embodiment of our invention.
Referring now to the drawing, Figs. 1 and 3 show oppositely disposed side frames 1 and 2 made up of the upper U-shaped side members 3 and 4 and the leg members 5, 6, 7, and 8, respectively. The legs 5 and 6 are joined together intermediate their ends by the lower frame member 9 and the legs 7 and 8 are joined together intermediate their ends by the lower frame member 10. The legs 5, 6, 7, and 8 are made of tubular material and are provided with casters 11, 12, 13, and 14 at the lower end thereof and the legs 5 and 6 telescopically receive the ends 15 and 16, respectively of the U-shaped top members 3 and 4. Spaced holes 17 are provided in the end 15 and spaced holes 18 are provided in the end 16.v These holes are adapted to adjustably receive the locking devices 19 and to support 2,733,754 Patented Feb. 7, 1956 the side frame 3 in a vertical adjustable position. Similar holes 20 and 21 are provided in the ends 22 and 23 of the U-shaped side member 4 and the ends 22 and 23 are integrally connected by the top member 25 which corresponds to the top member 26 which connects the ends 15 and 16 of the'member 3.
The tubular member 28 has a cross member 44 welded thereto similar to the member 31 and pivotally receives a member integrally attached to the cross member 42 at 45 and the cross member 42 is pivotally attached to the cross member 34 by the pin 46. The tubular member 47 is telescopically received in the member 28 and the member 48 is welded to the member 47 at 49. The offset member 50 is welded to the member 34 at 51 and held against removal from the hollow member 48 by the washer 52 which is attached to the end of the member 50 and pivotally and slidably engages the end of the member 48.
The top member 25 is vertically adjustable in the leg member 8 by means of the holes 20 which are adapted to adjustably receive the pins 53. A hole 54 is formed in the top of the top member 26 of the side member 1 to receive the back supporting member 55 and a similar hole 56 is formed in the member 25 to receive the back supporting member 57. Back supporting member 55 is bent outwardly at 58 and upwardly at 59 to receive the fabric material 60 which is provided with a hem 61 to receive the member 55 and provided with a hem 62 to receive the member 57.
The tubular member 63 is welded or by other means attached to the frame member 9 at 64 and telescopically receives the pin 65 which is attached to the brace 66 at 67 and which has the ends 68 and 69 bent at right angles thereto and provided with holes 70 which receive a pin 71 which pivotally engages the bracket 72 which engages the seat 73 at 74.
A screw 75 threadably engages the tubular member 63 and friction-ally engages the member 65 to adjust the seat 73 vertically. A tube 76 is welded to the lower frame member 10 at 77 and it slidably receives the pin 78 and the pin 78 is adjustably held against vertical movement by a screw 79. A lateral member 80 is welded to the pin 78 at 81 and is adapted to receive the brackets 82 which have the hooks 83 attached thereto and which have the normally bent members 84 which support the seat 73. Clamps or brackets 86 and 87 are provided. The clamps 86 and 87 have a top portion which is hinged to the bottom member 88 at 89 and which has the fastenthe screw 97. The brackets 87 are similar to the brackets 86 and they have the upper portion 98 and the lower portion 99 pivotally attached together at 100- and is threadably engaged in the member 99 to hold the clamps or brackets 87 against slidable movement on the arm or top member 25.
The vertical support member 103 is welded to the brackets 87 atv 1,94 and the upper end of the vertical Support. 103'telescopically receives the pin 105 which is welded to the body receiving frame 106 under the body engaging padding 107.. It will be noted that the frame 106 is provided with. the body engaging padding 107, 1118, 109, and 110 disposed around the periphery of the frame in order to provide a comfortable supporting surface for an invalid. The casters 11, 12, 13, and 14 have. wheels. 11 1, 112, 113, and 114, respectively, which are, pivotally received in the lower end of the tubular legs. 5, 6, 7, and. 8;, respectively, at 115, 116, 117, and 118, respectively.
In the embodiment of the invention Shown in Fig. 2,
we show the arms 225' and 226 supporting the fabric back 260 and having the back rest' support members 258 and 259 supported in holes 254 and 256 in the arm members. The vertical supports 244 and 2113 telescopically receive the members 205 and 296 and are held in a vertically adjustable position by screws 297 and 298.
The, padded members 220 and 221 are attached to the upper ends. of the members 296 and 20S and are adapted. to engage the armpits of an invalid using the walker. The crutches supported by the members 203 and 244 are adapted. to be used on the chair shown in Fig. l and substituted for the body supporting frame 166. Clamps 286 and 285 which are similar to the clamps 86 and 87 in Fig. l are adapted to hold the crutches on the walker shown in Fig. 1.
In Fig. 4, we show another embodiment of our invention wherein the back rest supporting member 158 corresponds tothe support .58 in Fig. 1. The support 153 has the struck out portions 155 thereon which may be formed by deforming a part of the metal of the back rest support to prevent the support 158 from sliding through the hole 154. The side member 3 corresponds to the side member 3 in Fig. 1.
in the foregoing specification, we have set forth the invention in its preferred practical forms but we are aware that the structure shown is capable of modification within a range of equivalents without departing from the'invention which is'to be understood is broadly novel as is commensurate with the appended claims.
