HAMMOCK-GHAIR FOR HANDLING INVALIDS.

specification of Letters Patent. Patented Sept. 24, 1918.

Application led May 17, 1916. Serial No. 98,160.

To all whom t may concern:

Be it known that I, EDWARD R. PERRIN, a citizen of the United States, residing at Wauzeka, in the county of Crawford and State of Wisconsin, have invented certain new and useful Improvements in Hammock- Chairs for Handling Invalids, of which the following is a Specification.

An object of my invention is to provide arhammock chair by which invalids may be handled and moved without exerting pressure upon any part of the body or limbs, and which chair is so arranged that the invalid may be taken up from the bed and moved to any desired point without being lifted by hand.

A further object is to so construct the chair in which the invalid is taken that the same may be built around a person as that person is seated on the edge of a bed andA the chair structure thus formed may then be suspended and raised to the proper relation to move the person from the bed after which the chair structure may be again lowered to its normal position, the same operation being pursued in placing the person back in the bed.v

With other objects in view, my invention consists in certain novel features of construction and combinations of parts which will be hereinafter set forth morefully in connection with the drawings and then pointed out in the claims.

In the drawings t Figure 1 is a view in side elevation of the device of my invention.

Fig. 2 is a top plan view of the structure disclosed in Fig. 1. p

Fig. 3 is a vertical sectional view to better illustrate the arrangement of the parts.

Fig. 4 is a detail view of the top of the back Structure. f

The support or base 1 is mounted on the casters or wheels 2 which are swiveled on the under side thereof and in this way the support is carried to be capable of traveling movement. The upright frame members 3 and 4 are mounted on the sides of thebase structure 1 at points approximately centrally of the longitudinal extent of the member 1, and are provided with bearing notches 5 on the upper ends thereof, and a brace member 6 is received between the studs 7 carried by the uprights and is wedged against the block 8 carried by the forward end of the base structure 1, suitable` hooks 9 or other suitable fastening means being provided to hold this supporting brace 6 in its proper relation. The chair structure proper comprises the upright or leg members 10 which are connected together at their lower ends by the cross bar 11, the side seat members 12 being disposed at substantially right angles to the extent of the leg members 10 and the back members 13 then extend upwardly from the outer end of the seat members 12. It is preferable that a block 14.- be mounted between the upright members 3 and 41 and that a block 15 be mounted rearwardly thereof in a spaced relation so that a socket is provided in which the lower ends of 'the leg members 10 are received when the device is being used and thus these members will be held against accidental displacement and will at the same time hold the chair structure against swinging or shifting movement. A cross bar 16 is provided to be mountedrbetween the leg members 10, a cross bar 17 to be received between the side seat members 12 near the forward end thereof, a cross bar 18 to be mounted between the rear ends of the side seat members 12, and the cross bar 19 to be mounted between the upper ends of the back members 13. A canvas or other fabric strip 20 has a wide hem or loop 21 formed on the lower end thereof to receive the cross bar 16, the canvas strip being then passed up over the cross bar 17, under the cross bar 18, and then upwardly and over the cross bar 19, and the upper end being drawn down to hold the main extent of the fabric in such relation that a seat and back portion are provided in the chair frame. This drawing down and stretching of the fabric strip may be accomplished by the use of a cord or rope 22 which has a central portion passed through rings or eyes 23 which are secured on the edge of the fabric strip, the rope 22 being then passed through the staples or loops 211 carried by the side members 13, and then down to a position adjacent the leg members 10 where hooks 25 are secured to the rope to be received through the staples 26 which are mounted on the sides of the leg members 10. The rope 22 also prevents the rear of the seat from spreading and thus causingthe rod 18 to escape from is sockets. By shortening the extent of the rope 22 in its connection with the hooks 25, the tension of the fabric may be varied and the seat and back portions provided for the chair may be drawn taut or may be given slack to better adapt `the same for the particular person with Whom it is to be used.

A supporting lever structure 27 is fulcrumed at 23 in the notchesor bearings 5 provided ,on the upper ends of the upriglits 3 and Il, the fulorum being preferably pro vided near one end of the supporting lever structure 27. The side seat members 12 have staples 29 `carried thereby and similar staples 30 are Amounted on the back members 13, a rope 31 being secured to the short end ofthe structure 27 and provided with a hook 32 to `be received in the staples 30 and a hook 33 Which is ,received in the staples 29. The Supporting frame structure 27 is preferably made, as is better illustrated in Fig. 2, with the side bars thereof disposed in a divergent and V-shaped arrangement, and it will be understood that -a rope or cord 31 is connected ,with each of the outer ends of these divergent side members and is led to the hooks32 yand 33, so-that support is provided for the chair frame ,structure at each side.

`A tongue 3l is mounted on the base member 1 and has a handle 35 provided so that the structure may be moved ordraWn over afloor and Will roll on the casters or Wheels 2,. At ,the forward end of the supporting v,frame structure 27, a rope 36 is secured at its Qneend and at the opposite side of the rope a hook 37 is provided, this rope being made ,of suoli a length that when the chair structure has been lraised to the proper elevation, the ,hook 37 ,may be engaged in a staple 38 carried on the forward end .of the base 1and thus the parts will be held in the ,properrelation A strip A39 is ,mounted in uthe. recess provided `between the block S and a block 4:0 inountedon the base 1 and this strip extends upbetiveen the cross bars 41 of the tongues 3,4, thus providing a support which reinforces the lmounting of this tongue, the strip being :then extended up between the side members of the supporting lever structure 27,. ,A pivoted block 42 :is provided to be swung down against this strip 39 to hold `the .same ,in engagement ,against the cross faneniber 43 with `ivhich the rope 36 has connectiomjand thus the supporting 'lever strucn .tureris k given V4greater ,rigidity and will thus be held against swinging down movement when the hooks 3 2 and 33 are disengaged from the Achair structure.

yIn ,the ,use of 4the device, the fabric strip 2O is spread on and 4Over the edges vof the bed, the `cross bar 17 heilig ,placed beneath .the sameata point Where the invalids knees will ,break over `the fabric, the cross bar 16 bein-g inserted through the looped portion 2l. The 'base 1 is Ainovetjl to a relation that jthe members 1Q, 12.and 13 of the chair frame .arevon each side of the invalid and then the cross bar 16 may be fitted in the sockets pronasales vided in the side leg members 10, the cross bar 17 is fitted in its proper relation, the cross bar 18 is laid across the fabric strip and is fit-ted in the sockets provided in the side back members, and the cross bar 19 has the upper end of the fabric laid thereacross and this cross member is then inseited'in the properI relation after which the rope 22 may be led through the rings or eyelets 23 and through the staples 2i and down to connect with the hooks 25 which are received inthe staples 2G to hold the lfabric strip stretched to the proper tension. With the parts thus `fitted, `the 'invalid is still resting on the bed and byexerting a downward pull on the outer .end of the supporting Llever structure adjacent the mounting` of the cross member` ,43, after raising the block 42, the chair structure will be raised `by reason of the fact that the hoolrs 32 and `have been inserted through the staples 30 and 29, and the handle 35 of the tongue 3st may -then "be `grasped and the "base and structure carried thereby rolled from the `point of proximity to the bed, after which the downward pressure exerted upon the structure 27 may be relieved and the parts Willbe supported Vin the relation shown in Figs 1 and y3 With the lower ends of the leg members 10 in the opening provided between : thebloclrs 14 and 15 and thus held against swinging or `twisting displacement.

it is preferable that the blocks et 'be mounted on the upright members 3 and lin a relation that they .will have ybearing against the leg members `10 from the outside to prevent displacement of the same, and in this connection it is also Aperhaps desirable that V,the stop blocks i5 be mounted on the uprights 3 and d in such a relation that as the cross bars and the fabric 'have been assembled in the 'chair frame, 1the side members 12 will be received between `these stop blocks 45 and the structure will thus `be .held against separating movement. A foot rest 46 is provided on the bra-ce member .and if desired, this foot rest might be made to be adjustable in any desired manner.

W'hile I have set forth only the manner in Which the parts are assembled {tomove an invalid from the bed, it Will ibe apparent that `the return to the'bed maybe accomplished inthe same Way 'by removing the structure, with the supported chair raised slightly, to a position adjacent the bed edge, then permitting the chair to lower so that the fabric seat thereof Will be uponthe edge of the bed and disassembling of the parts in the inverse order of their assembly.

In the present disclosure 'but a single vadaptationand construction ofthe device is illustrated, however, .it Will .be understood that various modifications might be resorted to in the form and arrangement of the parts as Well as in the manner of connecting'the same, and hence I do not Wish to be limited to the exact disclosure, but only to such points as may be set forth in the claims.
