Specification of Letters Patent.
Patented June 19, 1917.
Application filed August 26, 1914. Serial No. 858,682.
2' '0 all whom it may concern:
Be it known that l, ANNA S. JOHNSON, citizen of the United States, residing at Pierce City, in the county of Lawrence and State of Missouri, have invented certain new and useful Improvements in Bed- Chairs, of which the following is a specification.
This invention relates broadly to chairs and has particular reference to such articles of furniture which may be used in a sick bed to enable the patient to easily arise to and maintain a sitting position.
As the principal object, this invention contemplates the provision of a chair of the type described, the component parts of which shall be readily removable in order to be assembled about the patient in such a manner as to cause a minimum effort on the part of the latter.
A further object is to provide a ready means of retaining these parts in their assembled position when the device is in use.
An. object of equal importance with the foregoing is to provide a chair of the character disclosed which. shall be constructed with such regard to proportion, number and arrangement of parts as to be cheaply manufactured and as to be durable and eflicient in operation. I
The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.
Vith reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which like characters of reference designate similar parts,
Figure 1 is a side elevation of the improved chair comprehended by this invention as assembled,
Fig. 2 is a front elevation of the bed chair,
Fig. 3 is a detail perspective showing the manner of fitting the removable parts, and
Fig. 4 is a similar view showing another detail of assemblage.
There is shown in the drawings'an eX- tremely simplified form of bed-chair intended to accomplish the objects described and consisting mainly of a seat portion 5,
a back 6 and braced arm members 7 rem0vably connected to both the back and the seat, the former of which is likewise removably connected to the latter. The seat portion 5 has the suitably connected end members 8 which, as is also the seat portion itself, are suitably rounded upon their upper front edge as shown at 9 and on the lower rear edge as indicated at 10, in order to permit of the seat member being gently and easily inserted beneath the patient when the latter is in recumbent position, and also prevents any entangling engagement of the seat portion with the bedclothes.
The back portion 6 is constructed after the usual manner of ordinary chair backs comprising the uprights 11, the transverse top and bottom pieces 12 and the vertical slats 13, and is adapted to be removably secured in the seat portion 5 by means of the reduced extensions 14 formed on the lower extremities of the upright 11, such reduced ends seating in suitable cylindrical recesses formed in the rear of each seat end member 8 and being of sufficient length to insure a rigid construction when in place. Each of the uprights at the proper distance above the seat portion 5 to accommodate the arms 7 in their proper position, is transversely grooved from the front to the rear upon each side to a width equal to the width of the L-shaped bayonet slot in each member 7.
The side arm rests 7 are preferably curved outwardly from the back portion 6 and are provided with L-shaped bayonet slots 15 previously mentioned formed near the rearward ends as shown in Fig. 3 in order that the uprights 11 may be passed through the open end of the slots and removably seated in the closed end as shown. Each of these arm rests carries near its forward extremity the upright brace 16 secured at one end thereto and being formed upon the other with the reduced portion 17 and a succeeding rounded portion of larger diameter 18, such uprights being adapted to be inserted vertically into suitable grooves 19 formed on the outer faces of each seat end 8. .Transversely positioned across these grooves 19 are the springs 20 having the outwardly rounded central portions 21 "and being secured as shown at 22 to the outer face of the end 8, the curvature of :the portions 21 corresponding with the curvature of'the grooves 19 to equal that of the reduced. portions 17 of the uprights 16 so as to removably grip the latter when they are properly seatedbetween the grooves and the springs 20. In assemblage the parts ooact as follows:
After the seat portion 5 has been duly slipped under the patient, the latter is .assisted to a sitting position and the back 6 is properly positioned at the .rear of the seat portion with the extremities 14 securely seated in their proper apertures. Each arm 7 is then manipulated so as to embrace .the uprights 11 of the back by means of the bayonet slots 15 .and the upright braces 16 are properly inserted in. their respective grooves over which are held the springs 20.,
which, in gripping the reduced portions 1.7, will lie flush with the main .body ,of the brace as shown in Fig. 3 and form a reliable means for preventing casual .displacement of the arm rest 7. The enlarged rounded portion 18 merely serves as a means .of forcing the spring outwardly when the upright 16. is being inserted in its groove and also tends to prevent upward displacement of the arm rest. It-will be noted that if desired .a rearwardly extending leg 23 may be hinged .to the upper cross piece 12 to extend backwardly at an angle in supporting this improved bed-chair somewhat afterthe manner of a rear leg of an easel to prevent anyreclining tendency on the part of the patient from causing the device :to tip over backward although it will be understood that such auxiliary leg is not necessitated unless desired since the weight of the patient upon theseat portion 5 and the reliable con;nection between that portion and the back .6 will render any such tipping movement of the. chair extremely unlikely.
the other of such parts, in order to form a.
complete bed-chair when assembled and that by this construction the foregoing objects have been attained. This invention may therefore be claimed as possessing the advantages and desirabilities set forth in such in, u I.
5 I desire to emphasize the fact that I may make such minor changes in the matters of proportion and degree, in later adaptations of my device as shall not alter the spirit of my invention as defined in the appended claims.
What I claim is:
1. A bed chair including a seat, .a back removably connected to said seat, removable seat, and fastening means on both sides of said seat extending across the grooves therein to engage reduced portions of said posts and hold them in place.
2. A bed chair including a seat, a back re-- movably connected to said seat having upright side bars with reduced lower ends to engage the seat and .transverse grooves on opposite sides above said lower ends, removable arms each having a bayonet slot in its rear end to engage the grooved portions of the side bars and lock the arms in place thereon, fixed depending posts at the forward ends of said arms seated at their lower ends in grooves in the sides of the seat, and fastening means on-both sides of said seat extending across said grooves to engage reduced portions of said posts and I hold them in place.
3. A bed chair including a seat, a back removably connected to said seat having upright side bars with reduced lower ends to engage the seat, and transverse grooves on opposite sides above said lower ends, removable arms each having a bayonet slot in its rear end to engage the grooved portions of the side bars and lock said arms in place, fixed depending posts at the forward ends .of the arms fitting at their lowerends in vertical grooves in the sides of the seat, and a resilient fastening means secured on each .side of the .seat across the vertical groove and engaging a circular groove in the post to hold the latter seated in the vertical groove.
4. A bed chair including a seat having socket openings in the top at the rear corners thereof, a back formed with upstanding sidebars, their lower .ends projecting downwardly to be removably seated in said openings and position said back with relation to i the seat, grooves in opposite sides of the upright bars above their lower ends, a pair of arm rests formed with bayonet slots in their rear ends to removably embrace and lock with the grooves in the upright bars of said back, depending posts fastened in the forward ends of said arm rests and adapted to fit at their lower ends in vertical grooves formed in the sides of said seat, and means for'locking said posts in said .grooves.
In testimony whereof I affix my signature in presence of two witnesses.
