United States Patent DECK-CHAIR Robert Cassin, Nice, France, assignor of one-half to John M. Cassin, Beverly Hills, Calif.
Application October 10, 1956, Serial No. 615,171 Claims priority, application France April so, 1956 3 Claims. 01. 155-105 This invention relates to chairs. An object of the invention is to, provide an improved deck-chair made of pivoted members preferably formed of metallic tubes which, by the play of their pivotal action, enable the seat to be adjusted to various positions, namely a mean position deck-chair for relaxation, and on respective side of this mean position, a higher position serving as an ordinary chair and a lower position to form a In accordance witha preferred embodiment of the invention, the framework ofa deck-chair is composed of two articulated systems. One system, which constitutes the base of the seat, is composed of two members which will hereinafter be termed foot members, which are of U-shape. One of the members has a width which is slightly less; than that of the other; and, when engaged inside the other, forms a cross with the other member. A further member is provided which will be termed a seat member, and which is formed of two longitudinal meinbersl The assembly of these three members constitutes" a deformable triangular system, completed at its base by a fourth and lighter member which will be termed a foot stirrup member and whichfforming a deformabl'e quadrilateral with theother three, is pivoted at the vicinity oflth'ebase of one of thea'two foot members and can be engaged at different points on the other foot member in such manner as to fix the first articulated system at difierent angular positions of the deformable quadrilateral, which positions will correspond to different heights of the seat member with respect to the ground.
The second articulated system is formed by a further U-shaped member which will be termed a back memher and which is pivotally attached at the vicinity of its base to the upper extremity of one of the two foot members. To the base of this back member is articulated a further and lighter member which will be termed a seat stirrup member, the function of which, as will be explained in the text following, is to insure an automatic variation in the length of the canvas which forms the seat proper, the said canvas being fixed at one of its extremities to the upper part of the back member and at its opposite extremity to the seat stirrup member. This second articulated system is provided, by way of accessories, with arm-rests mounted on pivoted rods.
A third portion of the deck-chair consists of an extension, also of U-shape, which is slidably and adjust- .ably-mounted to form an extension towards the front and in line with the seat member in order to serve as a foot-rest.
Finally, the assembly of the articulated systems has been provided in such manner that it takes up only a small space when folded.
Further features will be brought out in the description which follows below, with reference to the accompanying drawings, in which there has been shown, by way of example, one embodiment of the deck-chair invention.
In these drawings:
Figs. 1 to 3 are views of the deck-chair in side eleva- 2,887,149 Patented May 19, 1959 2 tion, respectively arranged as a relaxation deck-chair (Fig. 1), as an ordinary chair (Fig. 2), and as a couch (Fig. 3).
Fig. 4 is a perspective view intended to show the details of the various articulations.
Fig. 5 is a view in elevation of the deck-chair in the folded position.
It is to be understood that in the drawings, in which, for the sake of simplicity, only one of the sides of the deck-chair has been shown, every member arranged parallel to a central vertical plane having a corresponding symmetrical part with respect to this plane.
The first articulated system comprises a first foot member in the form of a U, the arms of which are the upright members 1 and the base of which is the crossmember 2 (see Fig. 4), the latter resting on the ground,
preferably through the intermediary of fixed castors 3.
The other foot member, also in the shape of a U and of smaller width, is made up of the uprights 4 and the cross-member 5 (Fig. 4), contact with the ground being eliected through the medium of fixed casters 6. These two members, engaged one inside the other and crossed to form an X, are pivoted at their upper portions respectively at 7 and 8 to the longitudinal. members 9 of the seat member. The assembly of the uprights 1 and 4 and a longitudinal member 9 thus forms a deformable triangular system completed to form a quadrilateral by a foot stirrup 10, which is pivoted at 11 on the uprights 1, and the cross portion 12 of which (see Fig. 4) can be engaged in one or the other of the hooks 13 13 provided on the upright 4.
member 14, which is itself pivoted at 15 to the extremity of the upright 1. At the lower part of this back member 14 is pivoted at 16 the seat stirrup member 17;at a suitable part of this stirrup member is formed a bridge 18*adapted to come into engagement, at a certain stage of operation of the articulated systems, with a spindle 19 whichis an extension of the pivotal axis 7 of the members 1 and 9.
The canvas 20, which forms the seat proper, is retained at its upper extremity 20 on the top of the back member 14; at its opposite extremity, this canvas 20, after having passed round a cross member 21,. which couples one of the two uprights 4 to the other as shown in Fig. 4, is then fixed at 22 on the stirrup member 17 of the seat. On the other hand, an arm-rest 23 is pivoted at one of its extremities on the spindle 15 and at its opposite extremity on an arm 24 which is pivoted in turn at 25 on the seat stirrup member 17.
The deck-chair comprises in addition an extension member 26 in the form of a U, which is slidably-mounted on the front of the longitudinal seat members 9, as an extension of these latter and is engaged to this end in tubular guides 27, which are rigidly fixed to the said longitudinal members. This extension is: provided with a certain number of notches 28 by means of which it can be fixed in various positions of extension, by en gagement of any one of these notches with a bolt 29. Finally, the deck-chair is provided on each of its sides, with a further bolt 30, pivoted at 31 on the upright 1, and in which is formed at least one notch 32 adapted to engage a spindle 33 provided on the longitudinal member 9.
The operations to be effected in order to carry out the various transformations of the deck-chair are as follows:
Referring to Fig. 1 which shows the deck-chair in its mean position, especially suitable for relaxation, the member 10 is engaged in the lower hook 13 of the upright 4; on the other hand, the seat member 14 is roughly an extension of the upright 1 of the foot member, which corresponds to the maximum angular opening a which the back can assume with respect to the seat longitudinal members 9. The seat stirrup 17 is in its most forward position, so that the total length of the canvas 20 is employed. The foot-rest extension 26 may be pulled towards the front at the will of the user, by sliding the same inside the guide-tubes 27 to the length desired, and can then be fixed in the chosen position by engaging the bolt 29 in the appropriate slot 28 of this extension. Also, at the will of the user, the deck-chair can be locked in this position by engagement of the bolt 30 on the abutment 33.
In order to pass to the ordinary chair position shown in Fig. 2, it is only necessary to cause the back 14 to pivot with respect to the seat member 9 about the axis 7 in the direction which reduces the angular opening on. In this movement, the seat stirrup member is brought back in the direction of the. arrow which on the one hand brings the bridge 18 into engagement with the spindle 19, and, on the other hand, carries with it, in the same direction, the lower extremity of the canvas 20, the useful length of the said canvas being thereby shortened to correspond. The height of the seat remains the same, the foot stirrup remaining engaged in the lower hook 13 of the upright 4. The foot-rest extension 26 is fully pushed in, as shown in the figure. Returning to the mean position shown in Fig. 1, starting from this mean posi tion and proceeding in the opposite sense, the chair can be changed to the couch, position shown in Fig. 3.
To this end, it is only necessary to reduce the height of the seat by hooking the foot stirrup 10 in the upper hook 13 instead of inthe lower hook 13 of the upright 4, so as to reduce the angle ,8 at which the upright 1 and the back 14 are inclined with respect to the ground. In order to facilitate this operation, one of the arms of the foot stirrup 10 may be made in the shape of a pedal 34 (see Fig. 4) to which pressure is applied in order to keep this stirrup raised temporarily.
As in the case of the position shown in Fig. 1, the footrest extension may be moved towards the front, at the will of the user, to the desired length, and is then locked in this position. The use of the bolt 30 is optional.
Fig. 5 shows the deck-chair in the folded position for transport or storage when not in use.
What I claim is:
1. A deck-chair including pivoted parts, adapted for use in three selected positions, and comprising: a first foot member of substantially U-shaped configuration, a second foot member consisting of two transverse elements and two upstanding elements joined to form a frame fitted inside the first foot member to define a cross therewith, two longitudinal seat members, spindles pivoting the seat members to the upper part of both foot members, a foot stirrup member pivoted to the lower part of one of the foot members, means for adjustably hooking the foot stirrup member selectively to different 10- cations at the lower part of the other foot member, a back member pivoted to the upper part of the first foot member, a seat stirrup member pivoted to the lower part of the back member and including two bridges adapted to engage the spindles pivoting the longitudinal seat members to the upper part of the first foot member, and a canvas seat sling fixed at one end to the upper part of the back member, extending around the upper transverse element of the second foot member and fixed at the other end to the seat stirrup member.
2. A deck-chair as in claim 1 further comprising an extension member of U-shaped configuration having arms,
slidable in the longitudinal seat members and means IfOI locking the extension member in selected positions.
3. A deck-chair as in claim 1 comprising at least one bolt pivoted to the first foot member and having at least one notch positioned to engage a spindle on one of the longitudinal seat members.
