COMBINED DECK CHAIR AND ROCKING-CHAIR.

Application filed June 3,

To all whom it may concern:

Be it known that we, CHARLES WEST, of 65 Dunloe Avenue, London, N. 15, En land, and ARTHUR GREEN, of 271 Camden oad, London, N. 17, England, both subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in or Relating to Combined Deck Chairs and Rocking-Chairs, of which the following is a specification.

This invention relates to an improved construction of combined deck chair and rocking chair and refers more particularly to chairs of the kind consisting of substantially rectangular back and seat frames connected together on opposite sides by a pair of pivotal links, rods or bars, so as to permit the same to rock, the canvas or other material forming the seating being suspended from the top of the back frame and the front frame of the seat frame.

The object of the present invention consists in an improved construction of chairs of this kind which will be simple and inexpensive to construct, more comfortable in use and in which the relative positions of the frames ma be adjusted by the occupant of the chair ,without rising therefrom. A further feature of the invention consists in an improved construction and arrangement of the links and frames which permit the chair to be folded to a substantially fiat,

condition, the links or rods co-operating with stops to ensure the chair being opened out in the correct manner. Another object is to provide extension of the lower ends of the feet members of the scat frame to form stops to limit the movement and to also provide means for locking the frame in any adjusted position.

According to the invention, we provide two substantially rectangular frames, one of which constitutes the back frame and the other the seat frame. The canvas or the like 1922. Serial No. 565,710.

slightly bent or curved in o posite directions at their ends, the upper fdrward ends are bent or inclined forwardly and downwardly, whilst the rear ends are bent or inclined rearwardly and upwardly. By this means the cross member at the upper forward end may be located at a lower level than is possible with frames having-straight side members. The rear ends of the curved side members of the seat frame are pivotally connected to the side bars or the like on each side at a pointa short distance from their .ends so as to provide an extension which acts as a stop to limit the extent of rocking of the frames relatively to one another.

In order to facilitate folding of the chair into a substantially flat condltion, we prefer to connect the back and seat frames to the lower side bars or the like b horizontal pivots or pins passing theret rough, the

side members of the back frame being 10- catcd on the inside of said bars and the curved side members of the seat frame on the outside thereof. By this arrangement, the extension of the curved sides'of the seat frame contact with the ground or other surface on which the chair rests to limit the rocking motion thereof.

The side bars or the like rest entirely upon the ground or other surface whilst the ends of the seat and back frame are supported above the ground.

In this construction, the lower end -of the back frame is pivotally connected at its ends to the side bars at or near their forward ends, whilst the rear ends of said side bars are connected together b a cross member, which raises the rear en s off the ground and permits limited rocking of the seat frame about its ivotal connection without the extension t ereof contacting with the ground.

Various means may be adopted for securing the frames in any desired position so as to enable the occupant to adjust the chair to afford the maximum comfort without rising. y

In order that the invention may be readily understood, reference is made to the accompanying drawings, in which Fig. 1 is a side view of the deck chair.

Fig. 2 is a perspective view of the seat portion and part of the back portion.

Fig. 3 is a side view of the chair showing the same folded up.

Fig. 4 is a perspective view to a larger scale showing the securin means for t e chain between the back an seat frames.

Fig. 5 is a similar view showing one method by means of whichthe chain may be employed for securing the frames of the chair together in the folded condition.

Fig. 6 shows a' modified construction of the means for securing the frames in any adjusted position.

Fi s. 7 and 8 show two constructions in whic resilient means are employed to secure the two frames of the chair against rocking.-

Referrin to the construction shown in Figs. 1-4, idle chair is built up of two substantially rectangular frames hereinafter referred to as the seat frame and the back frame, respectively. The seat frame comprises longltudinal side members 10, 11 connected at their upper forward ends by a cross'member 12. The back frame consists of longitudinal side members 13, 14 respectively connected at their upper ends by a cross member 15 and in the neighbourhood of their lower ends by a cross member 16. As is usual with deck chairs, the back frame is made somewhat longer than the seat frame, as shown in the drawings, whilst the width of the seat frame is preferably slightly greater than the width of the back frame or vice versa in order to allow movement of one within the other. The lower end of the back frame is connected to the lower end of the seat frame on each side by the bar, rod or the like 17, one endof which is pivoted to the seat frame at a point 18, whilst the opposite end is similarly connected to the back frame at a point 19. The frames are also connected by a second bar,

rod, or the like 20 one end of which is pivoted to the back frame at a point 21, approximately mid-way between its ends whilst the opposite end of said bar is connected to the seat frame 22 a short distance from the upper forward end of the frame.

The canvas or like seating 23 is supported or attached to the cross member 15 of the back frame and at the opposite end to the cross member 12 of the seat frame.

The lower ends of the side members 13, 14 of the back frame are pivotally connected at their extreme ends to the bars 17 at a point 19, a short distance from the ends thereof, whilst the lower curved ends of the side members 10, 11 of the seat frame are similarly connected at a point 18, to the rear ends of the bars 17 the arrangement being such that the ends of both the bars 17 and the side members 10, 11 extend slightly beyond the point 18.

The front and rear ends of the two bars 17 rest upon the ground, the rear ends being connected by a cross member 24, the projecting lower surface of which, when resting upon the ground raises the rear ends of the bars 17 sh htly as shown in Fi 1.

' It will thus seen that the who e chair rests on the rods 17, and the cross member 24. The object of this arrangement is to prevent any movement between the frames and the ground when the chair is rocked, as 1n some cases, for instance, if the chair is resting upon soft ground or sand the rocking movement of the lower ends of the frames restin on the ground is likely to cause holes w ich after a time are likely to become enlarged and thus have a tendency to cause the chair to become embedded in the ground. By this arrangement of the bars 17, and the cross members 24, in the manner described, this disadvanta e is overcome and, further, the bars 17 an the cross member 24 offer a reater resistance to the ground than with 51c ordinary deck chairs as at present constructed owing to their having a considerably larger area of suppor The extensions 10, 11 of the side members 10, 11 at their rear ends are arranged to prevent rocking beyond certain limits and the point of connection 18 of said members being slightly raised from the ground, the chair may be rocked rearwardly within reasonable limits as shown by dotted lines in Fig. 1, the extensions 10, and 11' acting as a safeguard, especially when the chair is resting on sloping ground.

The side members 10, 11 of the frame are slightly bent or curved in opposite directions at each end, the curvature at the upper forward end enabling the front cross member 12 to be located at a lower level than is possible with frames having straight side members.

The arrangement of the connecting bars 17 and 20 between the vertical side members 10, 11, 13 and 14 of the back and seat frames respectively also facilitates the folding of the chair into a substantially fiat condition as shown in Fig. 3.

Various means may be adopted for securing the frames in any desired position, so as to enable the occupant to adjust the chair to afford the maximum comfort without rising.

In order to enable the chair to be secured against rocking, if the user so requires, we provide a chain, cable, cord or the like or a plurality of such devices, by means of which the frames are held together relatively to one another. WVhere a chain is employed, one end thereof may be attached to the lower cross member 16, of the side 27 of the bracket is cut awa to form a ton e or projection 28 whi c is bent slight y inwar ly, as shown in Fig. 3, wh lst the lower opposite edge may beformed with a guide or the like 29 bent outwardly to facihtate the movement of the chain. The tongue or rejection 28 is of such a size that when the inks of the chain are passed over its ends they both tend to fall by their own weight into enga ement with the tongue thus securing the c ain in any desired position. By this means the occupant of the chair is able to adjust the frames to any clesired position without rising from the chair, as by holding the chair in an upward direction the links pass over the inwardly projecting ton e 28 and when the frames have been moveg to the desired position the link for the time bein above the end of the tongue engages erewith and locks the frames to ether.

When t e chair is folded up as shown 1n Fig. 3, thischain may serve for retamm the ends of the frames in their collapse condition, the looped portion of the canvas seating 23 being wound round the ad acent members 12 and 15 to which its en s are connected, whilst the chain 26 1s wound round the outer side of the canvas, the chem bein provided with a hook or knob 30, whic engages one of the links of the chain as shown diagrammatically in Fig. 5, and

thus secure the two frame members in the folded or collapsed position. The frame members may be locked 1n any adjusted position by the means illustrated in Fig. 6, in which the rod 20 connecting the upper end of the seat frame to the back frame has pivotally mounted thereon a bar .or rod 31, provided with a series of notches 32 on one side and with a somewhat deeper notch 33 onthe opposite side. This bar is pivoted to the bar 20 at the point which normally is disposed slightly in front of a pin or stud 34 fixed to the side member 14 of the back frame. When the chair is rocked any of the notches 32 may be engaged with the pin 34 according to the position of adjustment required. When 1t is desired to adjust the chair to a position in which the back frame is inclined to its maxi- -mum extent, the bar 31 is rotated about its 'pivot so as to bring the notch 33 on the opposite side of the bar into engagement with the stud 34. The object of this arrangement is to enable the bar 31 to en age the in 34, when the pivotal point rom whic the bar is supported is moved to the opposite side of the vertical line passing through the stud 34.

In some cases it may be found desirable in order that the chair may not be subjected to sudden strains or stresses to provide resilient means gether.

Two methods of connecting the frames together with this object inview are shown in Fig: 7 and 8.

In construction shown in Fig. 7, the

for connecting the frames toone end of a coil spring 36, the opposite "end of which is connected to the cross member 16 connecting the side members 13, 14 of the back frame. With this construction the chain may be operated to engage the tongue of the U shaped bracket 25 as in the construction describedwith reference to Figs. 1 and 4, the spring serving to take up any shocks or strains caused by a person violently sltting in a chair and adding considerably to the comfort of the user.

In the construction shown at Fig. 8, the lower end of the chain 35 is connected to a rod 39, passing through a hole or. slot in the transverse member 16, connecting the side members 13 and 14. Between the head 40 of this rod and the cross member 16 is a coil spring 41.

By this means any chain 35 is taken u If desired the chain nated, the spring violent strain on the by the spring 40. may be entirely elimibelng connected at..one end to the cross bar 16, and at the other end to the cross member 12 of the seat frame.

The cross member 16 may if desired be rotatable, so that the rod and spring do not prevent folding up of the chair.

In order to ensure the frames being opened out from their collapsed or folded position, 1n the proper manner, a suitable stop may be PI'OVIdOd on one of WhlCh a portion of the other frame abuts when the frames are folded together. One simple method of effecting this object is shown by wa of example in Fi 1, in WhlCh one or 0th of the side mem ers 13, 14 of the back frame are provided in the nelghbourhood of their upper ends with a pro ectmg member 37 arranged in such a manner as to engage the end of the connectmg bar or rod 20 as shown in dotted l1nes at Figs. 1 and 3, the end of the bar or bars 20 being preferably cut off at an angle as shown at 38. By thls means the opening of the frames otherwise than in the correct manner will be prevented by the stops 37 It will of course be understood that the sto s may be located in any other position if eslre It will be understood that the details of constructlon' may be modified without departlng from the principle of the invention.

What we claim as our invention and desire to secure by Letters Patent in United States is 1. A combined deck chair and rocking chair comprising in combination substantially rectangular back and seat frameworks,

lower end of the chain 35 is connected to the frames against a base framework on which the chair rests,

. thereof, the side members of the seat framework being pivoted at their lower ends'to the side members of the base framework at the rear, the side members of the seat framework being extended beyond the pivots to form limiting stops, the side members of the back framework being ivoted at their lower ends to the side mem rs of the base framework at the front, a seating fabric having-its lower front portion supported by a member between the upper ends of the sides of the seat framework and its upper portion supported by a member between the upper ends of the sides of the back framework, link members on each side connectin the side members of the seat and bae frames, and means for maintaining the said frames in any adjusted postion, for the purposes set forth.

2. A combined deck chair and rocking chair comprising in combination substantially rectangular back and seat frameworks, a base framework on which the chair rests, comprising side members and a transthe ivots to form limiting stops, the side mem rs of the back framework being pivoted at their lower ends to the side members of the base framework at the front, a seating fabric having its lower front portion supported by a member between the upper ends of the sides ofthe seat framework, and its upper portion supported by a member between the upper ends of the sides of the back framework, link members on each side connecting the side members of the seat and back frames, and a chain adjustable between members of the back and seat frames for maintaining the said frames in any desired position.

In testimony whereof we have hereunto subscribed our names.
