Patented Mar. 28, 1939 UNITED STATES rATENT OFFICE LEG ELEVATOR FOR OPERATING CHAIRS Morgan W. Baker, Youngstown, Ohio Application September 28, 1937, Serial No. 166,129

2 Claims.

This invention relates to a leg elevator designed primarily for dental operating chairs. The principal object of this invention is the provision of an attachment for an operating chair 5 so designed that it will conveniently raise the legs of a patient in the event of the patients fainting, thus placing the patient in a reclining position and allowing the blood to flow to the brain to end the fainting spell.

A further object of the invention is the provision of a leg elevating attachment for operating chairs, so designed and positioned on the chair that in order to elevate the feet of a patient it is only necessary to push downwardly upon the handle of the elevator.

A further object of the invention is the provision of a leg elevator attachment for operating chairs, so designed as to form an attractive addition thereto.

A further object of the invention is the provision of a leg elevator attachment for operating chairs which is of light construction and easy to operate.

Patients in operating chairs frequently faint, thus making it necessary for the operator to relieve the fainting condition. A practical means of ending the faint is by placing the head of the patient at a lower level than the remainder of the body so that the blood may more readily flow to the brain. An operating chair is equipped with a foot rest at a substantially lower level than the r-est of the chair, and there is no provision in the majority of these operating chairs for elevating this foot rest. I have provided a convenient attachment for an operating chair which will elevate the feet and legs of a patient.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the'precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure l is a side elevation of an operating chair with my leg elevating attachment positioned thereon.

Figure 2 is a detail view of the leg elevating attachment in an elevating position, the relative position, of the operating chair being shown in dotted lines.

By referring to the 55 an operating chair,

with a leg elevator 6. This elevator The down-turned lower 6 is provided with a rubelevator.

The upper end of the leg elevator 6 is provided with a handle portion Ill, so designed that it may be folded up out of the Way when not in use.

By referring to Figure be seen that the leg elevator has been placed in an elevated position where it is held by means of a catch mechanism brackets 1. A plurality of notches l2 provided in the body of the elevator 6. seen that when the Il formed on one of the have been leg elevator is in this position,

the chair has been adjusted to a reclining position.l It is obvious that any patient in the operating chair will now be in a reclining position with their head at a substantially lower level than the remainder of th-e body, thus causing the blood to ilow more readily to the brain and relieve a fainting condition.

The leg elevator may 2 of the drawing it will 15 It Will be 20 operating chair as an accessory thereto, or may 30 be provided for at the time the chair is constructed by th e formation of the brackets l as an integral part of the chair itself.
