5 Claims. 1

This invention relates generally to a lifting apparatus designed primarily for use in lifting and moving invalids or injured persons.

A principal object of the present invention is to provide an apparatus of this character which is of relatively light construction and which can be easily moved from place to place either when loaded or unloaded and also is of such form that it may be run into aposition, with respect to a bed, whereby an ill or injured person can be placed directly on the bed or raised therefrom with a minimum of disturbance.

Still another object of the invention is to provide a carriage and lift apparatus of the character herein disclosed whereby an injured or ill person may be raised and lowered easily and smoothly without shocks or jars.

A further and more specific object of the invention is to provide an apparatus of the character stated wherein a supporting frame, formed in two sections which are relatively movable, includes telescoping parts with a novel and improved anti-friction means between the telescoping parts which will permit the device to be raised and lowered smoothly and Without binding or jamming.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of the specification, with the understanding, however, that the invention is not to be limited to the exact details of construction shown and described since obvious modifications will occur to a person skilled in the art.

In the drawing:

Figure 1 is a View in perspective, with portions broken away, of a lift apparatus constructed in accordance with the present invention.

Figure 2 is a detail view partly in elevation and partly in section of the central part of the vertical frame of the apparatus.

Figure 3 is a sectional view taken substantially on the line 33 of Figure 2.

Figure 4 is a fragmentary sectional detail through two bearing elements and adjacent part of a standard of which they form a part.

Referring more particularly to the drawing wheels is which, as shown, are attached to the transverse rails 12 at the ends thereof.

At the side of the base structure It is the vertical frame I4 which is in the same vertical plane as the longitudinal side rail II. The upright side frame l4, which is vertically extensible, includes as a part thereof the bottom l2 extending at right angles 2 rail II. From each of the two ends of the bottom rail ll extend the upright or vertical standards I5 which are in two telescoping parts a and b.

The top ends of the standards l5 are con nected by the top horizontal rail l6 and this rail, as shown, is integral with the upper ends of the sections a of the standards while the sections b are integral with the base rail II, the sections a being slidable into the upper ends of the sections b.

Extending downwardly and inwardly from the upper ends of the lower sections b of the standards are the bracing struts I! which are secured to the transverse rails I2 at a substantial distance inwardly from the longitudinal side rail II.

In addition to the end standards 15 there is the central standard l8 which comprises the telscopically joined upper and lower sections a. and b. The lower section b is secured rigidly to the longitudinal base rail ll centrally of its ends while the upper section a is joined to the underside of the top rail IS in spaced relation therewith. The means here shown for joining the upper section a to the top rail comprises the two angle brackets H! which are welded between the rail I6 and the section a but it will beobvious that other means may be employed for securing the parts in this relation.

In order that the vertical frame structure l4 may have a maximum of strength and rigidity there are provided the lower bracing struts 20 which are connected between the lower end of the lower section b of the center standard and the upper ends of the lower sections 1) of the adjacent standards 15. Above the struts 20 are corresponding bracing struts 2| which extend downwardly and inwardly from the upper ends of the sections a of the standards [5 to the lower part of the section a of the central standard to which they are firmly joined as illustrated.

At each end of the top rail is there is secured an end of an arched supporting arm 22 which projects inwardly to lie above the central part of the base frame It. Rigidly secured to the inner end of each arm 22 is an arcuate yoke 23, the concave side of which is directed downwardly as shown. The arms 22 are attached to the top sides of the yokes 23 substantially midway between the ends of the latter and it will be seen that the rail it, the arms 22 and the suspending yokes 23 are all joined together to form a rigid unit.

The depending free ends of each of the yokes 23 have secured thereacross the pivot pins 2t and each pivot pin has pivotally attached thereto a hanger hook 25.

The numeral 26 generally designates a carrier or stretcher which comprises the spaced side rails 21 between which is connected the fabric body 28. At properly spaced points the fabric body is provided with the openings 29 whereby the hooks 25 may be engaged around the stretcher rails 2'! thereby horizontally suspending the stretcher from the arched frames or yokes 23 in the manner shown.

Raising and lowering of the upper part of the vertical side frame [4, which upper part includes the horizontal top rail l6 and the parts a, (1', 2|, 22, and 23, is effected by means of the crank 30 which is connected with the upper end of a lifting screw 3i which extends downwardly through the tubular portion a of the central standard l8 and is threadably engaged in a nut 32 secured to the upper end of the lower portion 1) of the standard E8. The upper end of the screw 3| is connected with a thrust bearing 33 which is held in a space 34 provided between the upper end of the portion a of a central standard l8 and the overlying horizontal rail l6.

In order to effect movement of the end standard parts a with a minimum of friction in the lower parts I), rotatable anti-friction units are supported within the offset receptacles 35 which form a part of the lower part or section b of each end standard. These receptacles 35 open inwardly toward the inserted upper part a of the standard and have rotatably supported therein the bearing units or elements 36 between which the standard part (1 moves. These bearings 36 are in opposed relation and are disposed upon the inner and outer sides of the end standards and two sets of such bearings are preferably provided.

In order to add stability to the arched frames or yokes each has rigidly connected between the end thereof Which is adjacent to the vertical frame and the horizontal rail 1 6, the short brace arm 31.

From the fore oing it is believed that it will be readily apparent that a lift apparatus constructed in accordance with the present invention may be easily and quickly placed in position with respect to a bed or other similar structure upon which a patient may be resting and lowered and/or raised smoothly and. easily for the purpose of moving a sick or injured person. The construction and arrangement of the parts are such that after the patient has been raised the apparatus can be moved about easily without danger of tipping or upsetting.

By the provision of the hearings in the lower portions b of the end standards, the upper portions a of such standards can be made to shift without binding, regardless of the weight carried by the stretcher unit.
