Application October 7, 1946, Serial No. 701,836
Our invention relates to an improvement in walking supports.
Very often when people have had broken legs or other illnesses that impair their walking ability, it is necessary to provide some means of support so that the person may walk and move around.
Crutches have normally been used for this purpose but there are cases where the person feels insecure, even on crutches. Therefore to overcome this situation, we have provided our support for walking.
The object of this support is to provide a frame having a three point support and in which the person may stand and bear any portion of his weight, and steady himself by holding onto the frame with his hands.
A further object is to provide a support of the kind mentioned that will not easily tip, one that is strong and stable, and one that is light in weight so that it can be easily moved around.
A still further object is to provide a support of the kind mentioned that can be collapsed or taken apart and the pieces laid closely together for storage or shipping p poses.
Another object is to provide a support of the.
kind mentioned to which additional accessories may :be attached, such as a seat or crutch elements to relieve the person using the device from bearing his weight on his hands and arms.
Another object is to provide a device of the i kind mentioned, having friction skid supports therefor, whereby the device may be easily slid or moved along without the danger of possible skidding or slipping of the device as it might do if it were mounted on rollers or castors.
A still further object of the support is to provide a device of the kind mentioned, the height of which may be readily adjusted to fit the person using it.
These and other objects will be more fully explained as this description progresses.
Now referring to the accompanying drawings in which similar numerals of reference designate the same parts throughout the several figures of the drawings.

Fig. 9 is a top plan view of a modified form of the frame element connections such as would occur along the line VI--VI in Fig. 3.
Fig. 10 is a side view of the support, having crutch elements as accessories mounted thereon.
Fig. 11 is a front view of the support showing the crutch elements mounted thereon.
Fig. 12 is an enlarged detail sectional view through the crutch element and mounting thereof on the support and the view being taken along the line XII-XII in Fig. 1-0, and looking in the direction of the arrows.
In the drawings, the support is shown as having a front leg element I3, having a tubular transversely positioned cross head member l4, rigidly fixed, preferably welded thereon, and in the ends of which are detachably fitted, ends of curved and horizontally positioned supporting tubular element I5 and It, the rear ends of which are curved downwardly to form supporting legs ll and I8, having outwardly directed curved portions a, to set the lower portions of the legs l1 and i8 outwardly from the supporting rails 15 and I6, so as to make the frame more stable and less susceptible to tipping when it is being used.
The lower end of each leg l3, I1 and I8 is internally threaded to receive a threaded shaft IS, the lower end of which is provided with a skid head 20 that will rest on the floor as a support for the device.
A lock nut 2| is threaded on the shaft l9 and adapted to engage the lower end of its respective leg l3, H or l8, so that the shaft I9 may be screwed in or out of its respective leg 13, ll or I8 to adjust the height of the frame and when so adjusted the lock nut 2| may be turned on the shaft I!) to tightly engage the end of its respective leg [3, l1 or [8 as a means of locking the shaft l9 in its adjusted position.
The inner ends of the tubular supports l and I6 are reduced in diameter as indicated at a so that it will snugly slip into the tubular cross head [4 and a pin 22 is passed through the tube portion 15a with the ends thereof projecting on either side of the tube portion [5a. substantially the distance of half of the thickness of the wall of the tubular cross head l4.
The end of the tubular cross head 14 are provided with a pair of diametrically positioned notches 23 therein in which the ends of the pins 22 are seated. This prevents the ends of the tubular supports [5 and I6 from turning in the cross head 14 and therefore definitely and rigidly holds the supporting leg l3 in a vertical fixed position.
The ends of the cross head 14 are externally threaded to receive the internal threads of a collar 24, that is revolvably mounted on the reduced tubular end I50. of the tubular supports 15 and I6 and is provided with an inwardly extending flange portion that is positioned behind the projecting ends of the pin 22, so that when the collar 24 is screwed on the end of the tubular cross head 14, the flange 25 will engage and press the ends of the pin 22 into the notches 23, whereupon the tubular support elements 15 and l6 are rigidly attached to the tubular cross head elements [4 and are rigidly held in a horizontal plane.
In Fig. 9 is shown a modified form of the attachment of the support members 15 and I6 to the attachment element Ma, in which the notches 23 shown in Fig. 6 become slots 2311. as shown in Fig. 9 and at the end of the slot 23a is a side wise directed continuation 23b of the slot 23a in which the ends of the pin 22 are received and turned as will be readily understood to prevent the end [5a from pulling out of the attachment element Ma.
The tubular support element l5 and I6 are each provided with a hand hold 26 that are preferably made of tubular rubber and slipped on the tubular supports [5 and [6.
If desired, the support may be provided with a seat element 21 that is rigidly attached to a bracket 28, having a sleeve 29 formed thereon that may be slipped on the frame leg I8 to the desired height and a collar 30 may also be slipped on the leg 18 and rigidly fixed thereon by means of a set screw 3! therein as a support for the sleeve 29, whereby the sleeve 29 and seat 21 may be horizontally rocked or swung about the leg 18.
A second collar 32 may be slipped on the leg [1 and rigidly fixed thereon by means of a set screw 33 therein, the collar 32 being set at such a height that the adjacent end of the seat 21 is provided with a stop 34 that will engage the leg l1 as a stop for the seat 21. The end of the seat is also provided with a latch pin 35 that is slidably carried in the end of the seat 21 and is urged to move outwardly by a spring 36 that is positioned in the end of the seat 21 and behind the latch pin 35, so that when the seat 21 is swung into position between the legs I1 and I8 the latch pin 35 will engage the leg l1 and be forced into the seat 21 against the pressure of the spring 36 and as the seat advances in its swinging motion the stop 34 will engage the leg l1, whereupon the latch pin '35 will engage the leg l1, whereupon the latch pin 35 has passed the center of the curvature of the leg l1 and the spring 36 has moved the latch pin 35 outwardly behind the leg 11, whereupon the seat 21 is held in position solidly enough that the person using the support may sit down upon it. If it is desired to move the seat 21 so that the person using the support can move out of the support frame, the seat 21 may be pushed rearwardly, whereupon the latch pin 21 pushing against the curvature of the leg 11 will yield or move rearwardly against the pressure of the spring 36 and permit the swinging of the seat 21 so that it can be moved out of the way.
Now if the person using the support is in need of support further than that he receives by holding onto the hand holds 26, the support may be further provided with crutch supports that may be attached to the support tubes l5 and I6.
The crutch supports are made preferably of tubular elements 31 that are curved so that the lower ends may be supported by the tubular supports l5 and I6, and the upper ends are swung inwardly and provided with arm pit supports 38 that are positioned the proper distance apart to comfortably fit under the arms of the person using the support.
The lower end of the tubular element 31 is revolvably mounted on a pin 40 and rests on a collar 4| that is rigidly fixed on the pin 40 by means of a set screw 42 that passes through the collar 4! and bears against the pin 40.
The lower end of the pin 40 is welded to or integrally formed on a clamp member 43 which is associated with a second clamp member 44. The two clamp members 43 and 44 being positioned around their respective tubular support elements l5 and I6 and are bolted together by means of bolts 45 and 46, so as to hold the crutch support elements thereon.
The clamp elements 44 are provided with a pin 41 and project inwardly therefrom and are received in a hole 48 in their respective tubular support element [5 or [6 to prevent the dropping or swinging of the crutch elements 31 about their respective tubular support l5 or Hi When the support is not in use or during the time when the person using the support is entering o leaving or even while using the support.
