7 Claims, 5 Drawing Figures FEEDING DEVICE This invention relates to a feeding device adapted for use by persons having limited or no use of their arms, the device including a spoon and supporting means therefor. The supporting means comprises a base, posts mounted thereon, levers and counterbalancing means carried by certain posts, a fixed spoon-holder cradle on another post, and a spoon mounting and actuating assembly, the latter being adapted for manipulation by the users head, neck and mouth, to pick up a spoonful of food from a plate, to place the spoon holder on its cradle and, if desired, to move the filled spoon into a more convenient position for eating the food.

Children and adults may be, or become, afflicted with disabilities that result in little motor control due to a variety of causes including: congenital deformities such as arthrogryposis, Thalidomide effects, and bilateral above-the-elbow amputations; central nervous system involvements such as cerebral palsy, multiple sclerosis; and traumatic injuries such as spinal cord lesions. Depending on type, course and extent of the disease, injury or disability, the individual may be temporarily or permanently unable to perform any acts of independent living due to severe physical limitations.

It is an object of the present invention to provide the individual who is actually ill with an immediate accomplishment in independence.

It is a further object to provide what may be the only practical means of independence for the permanently disabled individual who lacks any functional upper extremity movement.

It is another object to provide, more specifically, an adjustable counterbalanced spoon mounting and actuating assembly which can be operated entirely by the users head, neck and mouth movements, in conjunction with minimal trunk control, to pick up food from a plate and locate it in a position to be eaten.

It is a further object to provide certain improvements in the form, construction and arrangement of the several parts whereby the above named and other objects may effectively be attained, and the invention accordingly comprises the features of construction, combination of elements and arrangement of parts hereinafter set forth, and the scope of the invention will be indicated in the claims.

A practical embodiment of the invention is shown in the accompanying drawings, wherein:

FIG. I represents a perspective view of the feeding device being operated by a handicapped person to pick up a spoonful of food (not shown);

FIG. 2 represents a perspective view of the device with the spoon mounting and actuating assembly resting on the cradle, in the position assumed before and after filling the spoon;

FIG. 3 represents a plan view showing the parts turned to the preferred eating" position;

FIG. 4 represents a detail vertical section on the line IV-IV of FIG. 3; and

FIG. 5 represents a detail vertical section on the line \/V of FIG. 3.

Referring to the drawings, the spoon 11 has a bowl 12 and a handle I3, the latter being attached to one end of the T-shaped junction 14 by means of a spoon adjustment knob 15, and the handle being bent substantially as shown. The opposite end of the junction is fixed to one end of the lever 16, and the opposite end of the lever 16 is connected to the guiding end counter balancing assembly I7.

The assembly 17 comprises levers I8 and 19, pivotally connected at 20, the lever I8 being loosely attached by the angle piece 21 to the end oflever I6 and the lever 19 being pivotally connected (for movement in a vertical plane) to the upper end of the post 22. Said post is constituted by a sleeve 23 threaded freely on a bolt 24. Maximum flexibility of the lever system may be assured by forming the pivot points of nylon or the like, with or without additional nylon washers. Pin 20' in the end of lever 18 acts as a stop (FIG. 2).

The weight of the assembly 17 and lever 16 is par tially balanced by the force of the spring 25, which extends from a lug l6 projecting upward from the lever 16 to a rod 26 adjustably mounted on the top of a post 27. Said post is constituted by a shaft 28, slidable on the vertical bar 29 and adjustable thereon by means of the shaft adjustment knob 30.

The

posts

22 and 27 are mounted in a base 34 which also carries a post 25 (similar to post 27 but shorter) on which is mounted the spoon-holder cradle 36. The latter is constituted by a small flat plate 37 having two

vertical walls

38, 39, disposed at a right angle and each being cut away to provide upwardly facing recesses 40, 41. A magnet 42 on the plate 37 aids in stabilization of the device. The base 34 may suitably be of plastic material such as Formica or plastic covered wood, and should be heavy enough to resist movement when placed on a table or the like and easy to clean.

The mechanism described above is operated by means of the mouthpiece assembly 45, consisting of a rigid tube 46 fixed at one end to the middle leg 47 of the T-shaped junction 14 and bearing on its other end a tubular plastic mouthpiece 48, the free end of which is flattened to an oval shape and provided with a head 49. The mouthpiece 48 is proportioned to be received comfortably in the mouth of the user, gripped as tightly as desired between the teeth and taking account of the fact that breathing through the tube 46 and mouthpiece 48 may be necessary.

In its at-rest position, the lever 16 is in the recess 40 and the tube 46 is in the recess 41, as shown in FIG. 2, the tension of spring 25 being adjusted to hold the spoon bowl 12 in level or slightly elevated position. The food to be eaten is supplied preferably on a plate 50 which has a separate or integral upstanding rim or plate guard 51 around at least part of its periphery to aid in loading the spoon. If the food is liquid or semi-liquid, it may be served in a dish of suitable depth.

In use, assuming a plate of food to be positioned on the base 34 (FIG. I) and the mechanism at rest as shown in FIG. 2, with the spoon approximately level with the users mouth, the user grips the mouthpiece, lifts the spoon supporting assembly off the cradle 36, and manipulates the spoon so that the bowl will pick up a quantity of food, normally by a sidewise pushing or endwise motion of the spoon bowl. When the spoon is loaded the parts are returned to the position of FIG. 2, and the user releases the mouthpiece, then gently nudges it with the left cheek (arrow 55) in order to swing the tube 46 out of the recess 41 and to bring the lever 16 and adjacent end of the junction 14 in line across the recesses 40 and 41, as shown in FIG. 3. This brings the filled spoon into a position extending directly toward the user so that the food can be most conveniently eaten. To repeat the operation, the mouthpiece 3 is nudged by the right cheek (arrow 56, FIG. 3) in order to return the spoon to the position of FIG. 2. Some users may find it possible to eat the food from the spoon without shifting its position, particularly if the angle between the spoon handle and the tube 46 is reduced.

The spoon and mouthpiece can readily be removed for washing and/or sterilization.

The physical limitations and capabilities of patients needing to use such a feeding device necessarily vary widely; it will be noted that individual adjustments can be made with respect to spring tension and angle, post heights, spoon angle and cradle position in order to achieve optimal convenience in operation for each individual.

It will thus be seen that the objects set forth above, among those made apparent from the preceding de scription, are efficiently attained and, since certain changes may be made in the above construction without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
