IIVVEIVTOR A Ham/5V8 arse-k ALBERTO GONZALEZ zuivieA, or LIMA, PERU.
Application filed May 24, 1915.
To all whom it may concern:
Be it known that I, ALBERTO GONZALEZ Zrifiroa, a citizen of Peru, and a resident of Lima, Peru, have invented a new and Improved Gomfort-Chair, of which the following is a full, clear, and exact description.
My invention relates to comfortable chairs, and has reference more particularly to a chair which can be adjusted to any desired position by the person occupying the chair.
An object of the invention is to provide a comfortable chair having a swinging back and foot rest with means for synchronizing their swinging movement.
Another object of the invention is to provide a comfort chair the seat of which is mounted to swing, with means for arresting the swinging movement of the seat.
A further object of the invention is to provide a comfort chair having a swinging back and foot rest, including means for locking the foot rest at a predetermined position while leaving the back of the chair free to swing.
A still further object of the invention is to provide a comfort chair in which there is a. swinging back and foot rest, with means for locking the swinging back at any desired point of the swinging arc of the back.
A still further object of the invention is to provide a comfort chair having a swinging back and foot rest which are foldable on the seat, and which back, seat and foot rest are collapsible longitudinally.
Another obj eot of the invention is to provide a collapsible support from which a comfort chair maybe suspended to swing, with means carried by the support to lock the swinging movement of the chair in the support.
With the above and other objects in view, the nature of which will more fully ap pear as the description proceeds, the invention consists in the novel construction combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Fig. 14 is an enlarged fractional side elevation of the lower portion of the upright of the support; and
Fig. 15 is a perspective view illustrating the connection of the upper end of the triangular suspension frame for the chair.
Referring to the drawings, the seat of the chair comprises two longitudinal bars 15 properly spaced. by transverse members 16 connected to the longitudinal bars adjacent the ends thereof and depressed below said longitudinal bars so that a flexible member 17 tied to the rods 18 will not, when weight is applied thereto, engage said transverse members 16. Each of the rods 18 is connected to a corresponding bar 15 and spaced therefrom to facilitate the tying of theflexible member 17 to the bars. A link 19 is pivotally attached between its ends to the front end of each of the bars 15. The link is preferably located between the bar and the corresponding rod. One end of a link is mounted on each pivot of the link 19. Each of the links 20 is preferably located between the link 19 and the corresponding rod 15. A link 21 is pivotally connected to the rear end of each bar 15.
The upper end of each link 21 is connected by a pivot 24 to a corresponding longitudinal bar 22 adjacent the lower end thereof. The lower end of each bar is cut on the bias and normally engages a pin 23 provided on each link 21. This bias is cut so that a movement of the bars from the longi- 'longitudinal bars 22 are properly spaced by a transverse member 25. Each of the bars 22 is provided with a rod 26 suitably spaced from the bar so as to facilitate the tying of the flexible member 17 to said bars.
The transverse member 25 comprises two pivotally connected sections 66, each con nected pivotally to the adjacent end oi? the bar 22 by an end portion 65 which is locked to a projection 27 on the bar by a slide 28, also on the bar, and actuated by a spring 29. The joint of the sections 66 has a stop 67 limiting the movement of the sections to alinement under the tension of the flexible member 17 engaged by the section 66. To move the sections it is necessary to unlock the end portions 65 from the bars and swing said portions from the bars.
A bar 30 connects pivotally each bar 22, above its pivot 24, and the other end of the link 20 which is on the same side of the chair seat. A lateral projection 31 is provided on each of the links 19 adjacent the upper ends thereof to be engaged by the links 20 when the back of the chair is swung downwardly, that is, away from the seat.
Pivotally connected to the lower end of each link 19 is a longitudinal bar 32. The said lower end of each link 19 is cut on the bias and is adapted to engage a similar biased edge of a projection 33 secured to the bar 32, whereby the bar 32 is maintained in alinement with the link 19 when the bias edges are in contact. These bias edges are so related that when the links 19 are mover on their pivots by the links 29 the longitudinal bars are caused to move therewith, or that, when the longitudinal bars are moved downwardly, the links 20 are caused to move with the links 19. It will be noted that the bias permits a free upward movement of the bars 32 without the links 19 participating in the said movement.
The portion of the flexible member 17 which extends from the seat between the longitudinal bars 32 is secured to rods 34,
similar to rods 18 and 26, and similarly spaced from the corresponding bars 32. The lower ends of the longitudinal bars 32 are properly spaced by transverse member 35 pivotally connected to each of the bars adjacent the lower end so as to swing outwardly. Said transverse member 35 is constructed similarly to the transverse member 25 and engages the lower end of the flexible member 17 and stretches longitudinally the portion of the flexible member extending between the bars 32 when said transverse member is brought into a plane with said longitudinal members. It is main tained in the plane with the longitudinal members by a locking device forming part of a foot bar or support 36. The foot bar is constructed similarly to the member 25 and is connected pivotally to the lower ends of the bars 32. The ends of the foot bar at the pivots are provided with a notch 37 adapted to engage a pin 38 on the transverse member 35 when said foot bar is at right angles to the foot rest, which is formed by the foot bar, the longitudinal bars 32, the transverse member 35, and the flexible member stretched therebetween.
The connection of the seat back with the foot rest by means of the bars 30 and links 20 causes the foot rest to swing upwardly when the back is swung downwardly. The downward swinging of the foot rest will cause an upward swinging movement of the back. The back can be locked to the seat at any desired position by a locking mecha nism provided on each side of the seat. The locking mechanism comprises an arcuate member 39, preferably semi-circular, the ends of which are secured to the corresponding longitudinal bars 22. The center of curvature of said member 39 is in the axis of the pivot 40 which connects the bar 22 with the bar 30. The arcuate member 39 passes between the bar 30 and a jaw 41 secured to the bar 30, so as to be free to move to and from the said bar. A lever 42 is secured to the bar 30, the fulcrumed end 43 of which bar is concave to engage the convex side of the jaw 41, so that when the lever 43 is moved into the position shown in Fig. 5, the jaw 41 clamps the arcuate member 39 to the bar 30 and prevents the back from swinging relative to the seat. It also locks the foot rest in its downward movement; although the foot rest is free to move outwardly, as can be easily seen from Fig. 5. When the end 43 of the lever is in alinement with the jaw, the back is free to swing.
The foot rest'may be locked to the seat when it is brought to a level therewith. The locking means is disposed on each side of the seat and consists of a slide 44 secured on the inner side of each bar 15. A spring 45 is associated with each slide 44 andnormally maintains one end of the slide in the path of the upper end of the corresponding link 19, so that when said links 19 are brought into alinement with the bars 15 they displace the corresponding slides to snap thereunder, whereby the foot rest is locked to the seat when the same is in plane therewith, as indicated in Fig. 2. To unlock the foot rest from the seat and maintain the slides 44 clear of the upper ends of the links 19, each slide 44 is connected to a pivotal arm 46 by a link 47 The link 47 is pivotally connected to the arm 46 at a point abovethe pivotal connection of the arm with the bar 15, so that the two pivots will be on a straight line, as shown in Fig. 5, when the slide 44 is moved to clear the upper end of the corresponding link 19. To maintain the arms 46 against the bars 15 when the slides 44 are in operative position, the links 47 en gage the slides 44 by means of elongated slots 48, so that they have an initial displacement relative to the slides and thus permit the arm to be folded against the bar 15, as shown in Fig. 2.
To render the chair still more comfortable, suspension members 49 are provided therefor. One of the suspension members 49 is connected to the bar 30 adjacent the rear end thereof, and the other adjacent the front end of the bar. The two suspension members are in pivotal connection with their other ends. The pivotally engaged ends of the suspension members 49 are made to en gage a notch 50 on an arm 51 extending laterally from Lip-rights 52 of the chair support. By the provision of this suspension means the chair is free to swing in the chair support; that is to say, a person occupying the chair can swing therewith.
To lock the seat of the chair, and therefore stop the swinging movement of the chair, a pawl 53 is provided in each of the uprights 52. Each of the bars 30 carries a depressible member 54 having a notch 55 adapted to be engaged by the corresponding pawl 53. Compensating levers 56 are provided for each pawl 53 to lock said pawl in operative or in inoperative position, as shown in Figs. 1, 3 and 4. The levers comprise a slotted link 56 pivoted to the upright 52 with one end and engaging with a pin at the other end the slotted end of a link 56 pivoted between the ends on the upright. The other end'of the link 56 is connected by a link 56 to the pawl 53. A handle 56 pivoted at one end to the upright 52 has a pin adjacent the pivoted end engaging the slot of the link 56*. The reason for making the member 54 depressible is to bring said member into engagement with the pawl after the said pawl has been locked in operative position by means of the compensating levers.
It will be noted that the suspension members 49 and the bars 30 form the suspension frame for the seat, from which the said seat issuspended and with relation to which frame the seat is movable. The suspension frame, as stated, can be locked by means of the compensating levers 56. This prevents the swinging movement of the frame, but the seat suspended from the frame is movable relative thereto whether the frame is locked or free to swing when the back is swung. Due to this arrangement, a person occupying the chair and applying pressure to the back cannot fall, as the downward movement of the back forces the seat to rise; therefore the pressure of the person applied to the back reacts against its own weight. Relief of pressure from the back and application of pressure to the foot rest helps the back to swing to a substantially vertical position.
As seen from the drawings, the seat, with its swinging back and foot rest, is suspended from the support, and, therefore, can be easily hooked off therefrom. The members 49 are separable on their common pivot and, therefore, foldable against the corresponding bar 30. To properly fold the member, the rear member 49 has a link 49 connecting it to the bar, whereby said rear member will fold on to the front member 49. In addition to the foldability of the foot rest on the seat and the back over the foot rest, the back, seat and foot rest are collapsible longitudinally by making the transverse members thereof collapsible; that is to say, the members 16, 25, and 35 and foot bar 36 are foldable.
The transverse members 16 of the seat comprise depending portions 57 rigidly secured to the bars 15. Pivotally connected to the depending portions 57 are end portions 58 to each of which is pivotally connected a bar portion 59. The end portion 58 and the bar portion 59 have biased ends 60 adapted to engage when the bar portions 59 and the end port-ions 60'are substantially in alinement, as shown in Fig. 8. The bar portions 60 are pivotally connected to each other at 61. One of the bar portions is provided with an extension 62 to which one end of an arcuate segment 63 is pivotally attached. The other end of the segment is pivotally attached to a lever 64 between its ends, one end of the lever being pivotally attached to the other bar portion 59. When the non-pivoted end of the lever 64 is brought into alinement with the bar 16, the biased ends of the bar portions 59 are moved into engagement with the corresponding biased ends of the end portions 58; and the end pivot of the lever 64 is below a straight line connecting the pivots of the arcuate member 63 and, therefore, it is below the dead center and locked. To collapse the bar 16 it is necessary to move the lever 64 in the direction indicated by the arrow in Fig. 8. The pivotal connections of the end portions 58 with the depending portions 57 permits the swinging of the transverse member 16 into a plane parallel with the longitudinal bars 15 when the transverse member is collapsed and draws the longitudinal bars 15 together. See Fig. 13.
The chair support is also made collapsible,
to render the transportion thereof easier.
Each upright has a central standard formed of two members 68 and 69 pivoted belowthe upper brace which is formed of two members 70 each pivoted to the member 68 to swing in the same plane. The lower brace of the upright is formed of two members 71, each pivoted to the link 76 which is in turn pivoted to the standard portion 69. Connected pivotally to each of the members 71 is a side member 72, each of which is, in turn, pivotally connected to one of the brace members 70. It will be noted that the pivotal joints of the members 71 and 72 are in a plane at right angles to the pivotal joints of the members 68 and 69. Side members 73 connect a socket 74, provided at the upper end of the portion 68 of the central standard, with the braces 70 to which the members 7 3 are pivotally connected and whereby the side members 73 and the portion 68 can be folded over the lower part of the upright of the support.
The two uprights of the support are interconnected at the bottom by the members 75 which are pivotally connected to each other and to the standard portions 69 above their links 76. The two members 75 are further connected by a jointed bar 77 having a looking link member 78 for retaining the jointed bar straight between the members 75 to prevent the movement of the uprights toward each other. The locking member 78 permits the bar 77 to collapse only when it is forced toward the members 75 and whereby the uprights are drawn toward each other.
The standard portion 68 has an extension 79 at the joint with the portion 69. This extension has a curved link 7 9 which is pivotally connected by a link 80 to the adjacent member 75. A spring-actuated pawl 81 is attached to each projection 79 to'engage a pin 82 provided on the corresponding portion 69 of the central standard. This pawl normally locks the member 68 to the member 69. By disengaging the pawl 81 from the pin 82, the upper part of the up-right can be folded toward the lower part of the standard. The folding movement of the upper part draws the members 71 of the lower brace inwardly, and, consequently, brings the two side members 7 2 toward each other. When the upper part of the upright is collapsed against the lower part, the two side members 72 are substantially parallel. After the two sides of the uprights are so collapsed, by collapsing the central part 78, the two collapsing uprights can be brought close together, thus greatly diminishing the space occupied by the support, which is very important for the transportation of the chair.
The side members 7.. are preferably pro vided with casters 83 to facilitate the rolling of the chair when the same is mounted. The arms 51 are also foldable in alinement with the uprights 52 as indicated in Fig. 12. The sockets 74 of the uprights are adapted to receive detachable stems 85. To one of the stems 85 a book support 8% is secured by means of a spring clamp 86 which extends from the book support to the stem. By compressing the ends of the clamp 86, the same can be moved on the stem so as to adjust the support. The book support 8 L swings in a horizontal plane on the clamp support 86; and it also swings in a vertical plane on a brace which connects it to the clamp, so that various adjustments of the book support may be obtained. Springs 87 are provided for clamping a book or any other reading matter to the support 84. The other stem 85, a portion only of which is shown, is intended for a table, which can be similarly adjusted on the stem by means of a similar clamp. This was omitted as the structure is substantially similar to what has been stated in reference to the book support.
From the above description it will be seen that in my chair a person occupying the same can easily control any desired position of the swinging back thereof and that the chair can be transformed into a lounge. There is no danger that a person occupying the chair will fall due to sudden application of pressure to the back of the chair, in view of the fact that the motion-transmission means which connects the back with the foot rest and the seat causesthe seat to move up wardly while the back moves downwardly, therefore reacting against the weight of the person occupying the chair. The collapsibility of the chair and the support thereof renders the same more easily transportable and therefore, more convenient.
The single flexible member 17 which engages the rods connected to the bars of the seat, back and foot rest, engages the transverse members only at the ends thereof; therefore no part of a person occupying the chair can come in contact with the transverse bars of the chair and thereby be rendered uncomfortable. The collapsible transverse members 16, 25 and 35 maintain the flexible member 17 on the seat, back, and foot rest of the chair when the same is in operative position, in cases where the chair is collapsible. The tautness of the flexible member 17 does not interfere with the foldability of the foot rest and back over the seat; but the tautness is destroyed when the seat, back, and foot rest are collapsed longitudinally,- as described.
