CONVERTIBLE BED AND CHAIR Filed May 20, 1935 5 Sheets-Sheet 3 Patented Mar. 24, 1936 UNITED STATES PATENT OFFICE Claims.

This invention vappertains to new and useful improvements .in furniture and .more particularly to furniture for'hospital use.

The principal object of the present invention is to provide a convertible bed and. invalid chair wherein the structure can be converted from a bed to a .chair without requiring the lifting of the patient from the structure.

Another important object of the invention is to provide a convertible bed and chair wherein the structure can be adjusted as a bed to a patient- ;reclining position, or conveniently from this position to the full bed position, or to an invalid vchair position.

These and various other important objects of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the structure in bed form.

Figure 2 is a perspective view of thespring used in the structure.

Figure 3 is a vertical sectional view.

Figure 4 is a side elevational view .of .the structure in chair form.

Figure 5 is a top plan view of the structure with the spring and mattress removed.

Figure .6 is a perspective view of one of the arm rests.

Figure '7 is a fragmentary detailed sectional view showing one of the joints.

Figure 8 is a top plan view of one of the joints of the frame structure.

Figure 9 is a side elevational view of the joint shown in Figure 8.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 5 that the .framework of the structure consists of the intermediate section 5, the head section 6 and the foot section generally referred to by numeral I. Pivotal joints such as are generally referred to by numeral 8 are employed for connecting the side tubes 9--9 of the intermediate section 5 to the side tubes or rails III-Ill of the head section 6 and the tubular side members II-II of the foot section I. As is clearly shown in Figure 8, these hinged joints each consists of a T-shaped member I2 having a bifurcated end portion I3 and a reduced extension I4 at its opposite end. The leg portion I5 engages into the corresponding end of the tubular cross member I6, there being a cross member I6 for each pair of hinged joints 8.

The hinge section IT for each of the joints is provided with a reduced extension I8 for engagement into the corresponding side member III or 'I I and this section I! is provided with a reduced extension I9 for engagement into the bifurcated end portion I3 of the corresponding joint member I2 where it is pivotally secured in place by 5 suitable pins or like members 20. Each of these joint members I2 is provided. with a. depending member 2| which engages into and is suitably secured to a corresponding leg member 22 .provided with a roller or caster 23 at its lower end. It can thus be seen in Figure 1 and also in other figures of the drawings, that this intermediate section 5 is provided with four legs which are fixed.

Numeral 25 represents the inverted U-shaped head member of the bed, while numeral 26 represents the foot member which extends upwardly in a general U-formation, the same being a continuation of the section I.

The head end of the side members III-I0 are slotted as at2'I and as is shown in Figure 7, collar members 28 having extensions 29 are secured to the said side members II] by disposing the extensions 29 into the slotted portion 21 of the side members III and pivotally securing the same in place as at 30. The collars 28 are loosely slidable on the vertical rails a of the head member 25.

A cross member 3| at the head ends of the side members III-I0 has the link members 32 connected thereto. These link members are also pivotally connected as at 33 to the bars 34, which are rockable on the cross member between the vertical rails a of the head frame 25. The remaining ends of these bars 34 are bridged as at 36. Obviously, these bars 34 operate as a unit, 35 and when the connecting member 36 is forced downwardly, the section 6 is tilted upwardly to the position shown in Figure 3 or further to the position shown in Figure 4. A metallic strap member 31 is connected at one end to one of the cross members I3 and this extends headwardly and is provided with a shoulder 38.

From the shoulderpoint 38 an extension 39 is disposed further headwardly to form a primary hook 40 and a secondary hook 4 I. When the primary hook 40 is engaged with the cross member 35 as shown in Figure 3, the sections of the bed are held with the head section 6 in the inclined position shown in Figure 3, and furthermore, the strap member and extension 39 will not collapse at the hinged shoulder 38 when the hook is so engaged. When the bed is in bed-forming position as shown in Figure 1, the secondary hook II is engaged in the cross member 35.

When the bed is entirely converted into the chair form shown in Figure 4, the shoulder 38 is engaged over the cross member 35, as suggested in Figure 4.

Elongated rods 42-42 (see Figure extend from clamp 43 on the cross member 3| to pivotally connect as at 44 to the caster carrying bars 45-45, which are pivotally clamped as at 46 to the cross member 41 bridging the foot members Hl I, which are cross braced as at 48. A collapsible brace 49 is provided between the swinga'ble legs 50 at the section 1 of the bed and the side members 99 of the intermediate section 5, so that when the bars 34 are swung downwardly to the position shown in Figure 4, the action of the rising section 6 pulling on the rods 42 will exert pull on the caster carrying members 45 so as to pull the section 1 downwardly to the position shown in Figure 4.

Figure 2 shows a spring for the bed made up of the sections 5a, 6a, and la hingedly connected together as at 8a. Numeral 5| represents a suitable mesh filler for the sections having the requisite amount of flexibility.

Numeral 52 represents a mattress which is made up of the sections 51), 6b, and 1b, the sections being connected together by thewebs 53 so that they will readily hinge.

As can be seen in Figures 5 and 8, the joints 8 are provided with sockets 55 for the reception of the pintles 56 which extend from the props 51-51 of each arm rest 58 (see Figure 6).

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is: V

1. A convertible bed and chair comprising a bed frame divided intd an intermediate section, a foot section, and a head section, pivotal connections between the said sections, means supporting said pivotally connected sections including a head piece provided with vertical rails, slidable connections between the vertical rails and the head section, a ro'ckable member on the head piece, and a pivotal link member between the said rockable member and the head section whereby the head section can be tilted to reclining position when the rockable member is actuated.
