H. R, RESAR COLLAPSIBLE LAWN CHAIR Jan. 11, 1966 Filed April 8, 1964 2 Sheets-Sheet 1 INVENTOR. HERBERT RESAR Attorney Jan. 11, 1966 H. R. RESAR 3,228,724
COLLAPSIBLE LAWN CHAIR Filed April 8, 1964 2 Sheets-Sheet 2 INVENTOR. HERBERT RESAR BY WW A Horn e y United States Patent M 2 1 Claims. ('01. 297-45 This invention relates to collapsible furniture and more particularly to collapsible chairs.
In the prior art, the provision of collapsible chairs is well known, but these chairs while of simple construction, have frequently been difficult or awkward to assemble and when assembled, have not proven completely stable or reliable because they have tended to collapse completely under weight.
One of the principal objects of the prior art chairs has been to provide facility of storage and transportation, hence their collapsibility. However, for the most part, their collapsible characteristics have been such that they are limited to collapse either in one plane or when collapsed, extend through as about a main plane.
In the chair now provided, it is so constructed that it may be collapsed through at least two planes: one section meing movable through a vertical and a horizontal plane and a second section having members movable laterally.
It is the main object of this present invention to pro vide improved collapsible furniture.
It is a further object of this present invention to provide an improved collapsible chair which is simple and economical to manufacture.
It is a further object of this present invention to provide a collapsible chair which will permit collapse of respective sections through different planes so that the chair may be more compactly stored or shipped;
In accordance with the present invention, the collapsible chair comprises a seat portion including a pair of spaced apart rigid side members, a flexible seat member secured to and extending between said side members, said side members each including at least one downwardly extending leg portion; a first bracing member secured to and extending between said downwardly extending leg portions of said side members; and a second bracing member extending between and secured to a second pair of depending leg members, each of said second pair of depending leg members being connected to a respective one of said side members in spaced apart relationship from said first mentioned leg portions, said bracing members each comprising at least a pair of swivably mounted rigid half members extending inwardly toward the immediately opposed depending leg member and a rigid connecting member hingedly connected to the inner end of each of said bracing half members to restrain outward movement thereof.
This construction gives several advantages in storage, in transportation and stability of the assembled chair which will be more evident from the description and drawings in which a specific embodiment is described by way of illustration and in which:
FIG. 1 is a front perspective view of a chair in accordance with the present invention;
3,228,724 Patented Jan. 11, 1966 FIG. 2 is a perspective view taken from one side of the chair of FIG. 1 in a partially collapsed condition;
FIG. 3 is a further perspective view of the chair illustrated in FIGS. 1 and 2 in a completely collapsed condition.
Referring now to the drawings and in particular to FIGS. 1 and 2, the chair comprises a seat and back portion generally indicated at 1 and 2 respectively. The seat portion 1 in turn, comprises side members 3 and 4, preferably tubular to reduce weight, which have at their forward ends thereof, downwardly turned leg portions 5 and 6 respectively. Stoppers 7 and 8 are inserted in the ends of leg portions 5 and 6 to provide ground engaging means. As will be observed in FIG. 1, the side members 3 and 4 are inclined downwardly toward the rear thereof and they terminate in members 9 and 10 respectively, again preferably tubular, each of which provides an integral rear leg and arm of the chair. The arm portions 11 and 12 of members 9 and 10 are supported in spaced apart relationship from their respective side members 3 and 4 by means of vertical supports 13 and 14; arcuate members 15 and 16 are secured to the inner sides of the arm portions 11 and 12 adjacent to the point where the members 9 and 10 turn downwardly into the leg portions 17 and 18 respectively. Between the side members 3 and 4, a flexible seat portion 19 is secured in any conventional manner although a particularly convenient arrangement is to wrap the sides of a suitable length of material comprised of canvas, saran or the like, around the side members 3 and 4, and then stitched into position. It is particularly to be noted that no cross member is needed to support the flexible seat 19. The ends of the downwardly extending leg portions 17 and 18 of the members 9 and 10 are provided with ground engaging stoppers 20 and 21 and the leg portions 17 and 18 of the members 9 and 10 are secured to the side members 3 and 4 respectively by means of brackets 22 and 23.
On the downwardly extending leg portions 5 and 6 of the side members 3 and 4, respectively, brackets 24 and 25 are pivotably secured, and they include inwardly extending flanges 26 and 27. The flange 26 carries a pair of parallel bracing members 28 and 29 extending inwardly towards the opposed leg portion 6 whilst the other flange 27 carries a similar pair of parallel bracing members 30 and 31 extending towards the opposed leg portion 5. The inner ends of bracing members 28 and 29 are hingedly secured to one side of a bracket 32 and the inner ends of the other bracing members 3%) and 31 are hingedly secured to the other side of the bracket 32. In the embodiment of the invention shown in FIG. 1, the bracket 32 comprises an upper channel portion 33 presenting a wall 34 to the front of the chair and a lower channel portion 35 having an outer wall 36, again facing forwardly. These two channel portions 33 and 35 are connected by a web 37 and to facilitate bending, the wall 34 is cut away as at 38 and 39 and the wall 36 is cut away as at 40 and 41. I
As will be observed in FIGS. 2 and 3, an arrangement similar to that already described for connecting the leg portions 5 and 6 is also used to connect the downwardly extending leg portions 17 and 18 of the members 9 and 10 respectively. A pair of brackets 42 and 43 are rotatably secured to the leg portions 17 and 18 respectively and these brackets 42 and 43 have flanges 44 and 45 respectively, from which rigidly seoured tubular bracing members 46 and 47 extend inwardly towards each other. A channel like bracket 48 is hingedly secured adjacent the inner ends of tubular members 46 and 47 and the bracket 48 comprises top and bottom walls 49 and 50 respectively, spaced apart by a web 51 which restrains the outward movement of the bracing members 46 and 47 when they are rotated about the leg portions 17 and 18. To facilitate hinging, the web 51 is cut away as at 52 and 53. j e a The back portion 2 comprises a lower and upper part denoted by 54-land 55 respectively, the lower part 54 being constructed by a pair of spaced apart tubular side members 56 and 57, the lower ends of which are curved forwardly to be hinged by means of pins 58 and 59 to the respective tubular side members 3 and 4. Across and between the tubular side members 56 and 57, a first back support panel 60 is secured which may be made continuous with the flexible seat 19 though it will, of course, be understood that it may be provided as a separate panel. In either case, it is conveniently secured to the side members 56 and 57 in the manner already described for the flexible seat 19. As shown in FIG. 2, the top end of the tubular side members 56 and 57 are cut away as at 61 and 62 respectively to form projections '63 and 64 which, in the particular embodiment, provides support for the upper part 55 of the back portion 2. This upper part 55 is constructed of a pair of spaced apart tubular side members 65 and 66 which are provided with caps or stoppers 67 and 68 respectively on their upper ends. A separate back or head support panel 69 is secured between the side members 65 and 66 in the manner already described for the back support panel 60. At the lower ends of the tubular side members 65-and 66, a pair of tubular projections of reduced diameter 70 and 71 are rigidly secured and these are provided with longitudinally extending slots 72 and 73. The lower. end of a bracket 101 having a pair of opposed sides 74 and 75 disposed on either side of a tubular side member 56 is pivotally secured to the upper end thereof adjacent to the projection 63 by means of a pin 76 and theupper end of the bracket 101 is slidablysecured by a pin 77 which extends through a slot 72 positioned in the tubular projection 70. A similar arrangement connects the tubular side member 57 with the upper tubular member 66, the side members 78 and 79.-of a corresponding bracket 102 being slidably engaged at their upper ends by a pin 80 in the slot 73, whilst the lower end of the side members 78 and 79 are pivotably secured by a pin 81 extending through the side member 57. r v
Intermediate the ends of the upper side members 65 and 66, a pair of bracing members 82 and 83 are hingedly secured in the manner illustrated in FIG. 2, by means of pins or rivets 84 and 85 respectively, and the inner ends of the members 82 and 83 are hingedly secured together by means of a bracket 86 havinga solid wall portion 87 which in the normally asembled condition, faces downwardly.
The chair will be received initially as illustrated in FIG. 3 with the bracing members 28 and 29, 30 and 31 and also 46 and 47 broken inwardly so that the'side. members 3 and 4 are pushed together; the backmembers-56 and 57 and 65 and 66 will also be pushed together, but it will be observed that the lower back portion 54 is also folded forward by virtue of the hinging on the pins 67 and 68 and the upper back portion 55 will be folded backwards.
To open the chair, the side members 3 and 4 are pulled apart so that the seat portion 19 is tightened therebetween. The bracing members 28 and 29, 30and 31 will swing outwardly towards the front and bracing members 46 and 47 towards the rear of the seat 19. When the side members 3 and 4 are fully extended, the respective bracing members will extend substantially normally from the leg members and 6 and 17 and 18m be locked in position and thereby restrained from further outward movement by thefront vertical walls 34 and 36 and the web 51. The lower back portion 54 is then pushed backwards moving hinged members 56 and 57 about the pins 58 and 59 respectively, until the members 56 and 57 engage in position with the arcuate brackets 15 and 16. The upper back portion 55 is raised at the same time as illustratrated in FIG. 2 and is pulled up to the full extent of the travel of the pins 77 and, in the slots 72 and 73 respectively, after which, the tubular projections 70 and 71 on the upper members 65 and, 66 seat in the upper projections 63 and 64 of the lower side members 56 and 57. The pins 77 and 80 will, of course, during this motion slide up in the slots 72 and 73 and.a lock will be effectively secured. Atthe same time, the bracing members 82 and 83 extending between the side members 65 and 66 will be pushed upwardly and secured in position by the lockingbracket 86.
To stow the chair, all that is necessary is to be reverse the above procedure;
It will be seen from theabove description, that the structure provided in this present application provides a comfortable seat, there being no transverse bars to disturb the comfort of a person sitting upon the chair, and the weight of an individual sitting upon the chair will .tend to lock the various bracing members into firm enthat the embodimentdescribed is described by way of example only and many of the modifications to the structure will be obvious to those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
