BED RAIL Filed July 1965 a United States Patent 3,221,350 BED RAIL Truman L. Atkinson, 609 Lake Shore Drive, Ludington, Mich. Filed July 15, 1963, Ser. No. 295,160 11 Claims. (Cl. 331) This invention relates to an adjustable bed rail for preventing a person from falling off the side of a bed. More particularly, this invention relates to an improved bed rail construction particularly designed for institutional use such as hospitals, nursing homes, sanitariums, etc.

Bed rails presently in existence are cumbersome structures, complicated in operation and expensive because of their complexity. Because of the size and the number of parts utilized in such bed rails, they often interfere with care of the patient. An improved type of bed rail is shown in my United States Patent No. 3,080,577 entitled Bed Rail, issued March 12, 1963. The present invention retains the general simplicity in structure achieved with the construction shown in this patent. However, the present invention discloses an improved means for actually adjusting the bed rail. Further, the adjusting means is such that an institution can adjust the bed rail and the patient on the bed is positively prevented from changing the height of the rail.

It is therefore an object of this invention to provide a simplified bed rail which utilizes an improved means for adjusting its height.

Another object of this invention is to provide such a bed rail which, when adjusted, cannot be changed by the patient on the bed.

A further object of this invention is to provide such a bed rail which does not interfere with the care of the patient at any time.

An additional object of this invention is to provide such a bed rail which may be quickly and simply removed from the bed itself.

A still further object of this invention is to provide such a bed rail which is positive in function, yet is so simple in construction that cost is substantially reduced.

These and other objects of this invention will become obvious to those skilled in the relevant arts upon reading the followng specification in conjunction with the accompanying drawings, wherein:

FIG. 1 is a front view of the bed rail comprising this invention;

FIG. 2 is an exploded, perspective view of one of the brackets forming a component of the bed rail shown in FIG. 1;

FIG. 3 is a plan view of the bracket shown in FIG. 2 as assembled, the bracket being in the nonclamping position;

FIG. 4 is an enlarged view of the movable element which cooperates with the bracket as shown in FIG. 3;

FIG. 5 is a plan view of the bracket, similar to the view shown in FIG. 3, the bracket being in clamping position; and

FIG. 6 is a view of the movable element similar to FIG. 4 positioned when cooperating with the bracket as shown in FIG. 5.

Briefly, this invention relates to an adjustable bed rail for preventing a person from falling off the side of a bed including a guard frame having a pair of depending legs. Clamping brackets slidably receive the legs, the brackets adjustable from a first position gripping the legs to a second position allowing the legs to move freely therein. A movable element is positioned between the brackets, rigid rods connecting the element to each of the brackets. Means is provided for moving the element, thereby moving the rods and the bracket between the positions noted.

Referring more specifically to the drawing, the reference numeral 1 designates an embodiment of the bed rail as made in accordance with the teachings of this invention (FIG. 1). The bed rail 1 includes a guard frame 2, a pair of brackets 10, a movable element 25 and connecting rods 30.

The guard frame 2 includes a pair of depending legs 3 and 4 and a plurality of guard members 5. At the lower end of each of the legs 3 and 4, a knob 6 is provided, the purpose of which will be explained hereinafter. A pair of brackets 10 are secured to a bed frame F. As best shown in FIG. 2, each of the brackets 10 includes a mounting element 11 having a first clamping arm 12 secured thereto. The clamping arm 12 includes a shaped recess 13 adapted to receive the leg 3 and an opening 14 extending through the clamping arm itself. A second clamping arm 15 is shaped to bear against the edge of the mounting element 11, the second clamping arm 15 also having an opening 16 extending therethrough and a shaped recess 17 for receiving the leg 3.

A movable element 25 (FIGS. 1, 4 and 6), comprising a pivot block in the embodiment shown, is pivotally secured to the bed frame F by means of a pivot bolt 26. The top of the pivot block 25 has a recess 27 to receive the handle 28 (FIG. 4). A pair of rigid rods 30 are pivotally connected to the pivot block 25. It will be seen that the rods 30 extend to each bracket 10, the respective rod extending through the

openings

14 and 16 in the clamping arms 12 and 15 (FIG. 2). A coil spring 18 is provided to envelop the respective rod 30, lying between the clamping

arms

12 and 15. A nut 31 secures the respective rod 30 in position. Thus, the clamping arm 15 is movable with respect to the clamping arm 12, the spring 18 normally biasing the clamping arms apart.

In operation, the legs 3 and 4 of the guard frame 2 extend between the clamping arms of the brackets 10. This may be accomplished when the clamping arms are positioned as shown in FIG. 3, the knobs 6 on the legs 3 and 4 being movable between the clamping arms by cocking the entire guard frame slightly and inserting the legs one at a time. The position of the clamping arms as shown in FIG. 3 is achieved when the movable element 25 is positioned as shown in FIG. 4. When one has positioned the guard frame 2 at the desired height, the handle 28 is moved upwardly from the position shown in FIGS. 1 and 4 to the position shown in FIG. 6. By so moving the handle 28, the pivot block 25 moves about the pivot bolt 26, thereby drawing the two rods 30 toward each other. By drawing the two rods 30 toward each other, the respective clamping arms 15 are drawn tightly against the clamping arms 12, thereby firmly locking the respective leg of the guard frame between the clamping arms. The handle 28 is then removed from the socket or recess 27 and the guard frame is rigidly locked in position. There is no way in which the height of the guard frame can then be adjusted.

However, when one desires to adjust the height of the guard frame 2, one merely inserts the handle 28 into the socket 27 and moves the handle to the position shown in FIG. 4. By so doing, the rods are moved apart from one another, and the springs 18 bias the clamping arms of each bracket apart. The legs 3 and 4 of the guard frame are then once again free to move with respect to the brackets 10. The guard frame 2 may then be removed from the brackets 10 by lifting it upwardly, cocking it slightly and removing one leg at a time through the respective clamping arms of the bracket. It will be seen that the height of the guard frame may be readjusted by positioning it to the desired height and moving the handle 28 as described hereinbefore.

It will now be seen that this invention has provided an improved bed rail which may be quickly and simply adjusted to any desired height. Further, once the bed rail is so adjusted, it is impossible for the patient in the bed to in any way tamper with the height of the bed rail. These results are achieved through an extremely simple structure which operates positively, yet retains the desired simplicity. The guard frame may be removed from the bed quickly and simply as well as varied in height.

While only one embodiment of this invention has been shown and described, it may be possible to practice the invention through the utilization of certain other embodiments without departing from the spirit and scope thereof. Such other embodiments are to be included as part of this invention unless the following claims specifically state otherwise.
