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.
