Claims.
This invention relates generally to chair construction, and more particularly to an improved beach or lawn chair.
My improved beach chair comprises a main frame adapted to rest on the ground; and a back frame, pivotally mounted on the main frame and covered with suitable material-to provide a' back rest. A seat is stretched between a cross-bar on the back frame and one arranged onarms pivoted in the main frame. When the chair. is set up for use the seat section is located somewhat above the main frame, above the ground. Novel seat supporting levers associated with the pivoted arms come into action to fixedly support the seat when in the set up condition.
The back section is arranged to be folded onto the main frame. When my novel beach chair is folded, its thickness does not exceed the thickness of the main frame. The back frame as well as the seat supporting levers and arms are housed well within the main frame. The particular construction of the levers connected with the seat supporting arms makes the folding and the setting-up of the chair particularly simple. In its folded state the improved chair can be easily carried or stored, requiring a minimum of space.
It is accordingly an object of the present invention to provide an improved collapsible beach chair of light weight, compact, strong, and durable construction.
Another object of the invention is to provide a beach chair of the type referred to, which is very flat and compact when folded up.
A further object of the'invention is to provide an improved collapsible chair which can be readily folded and unfolded by simple swinging of its back frame.
Still another object of the invention is to provide an improved beach chair having a guided seat supporting lever construction, facilitating folding and unfolding of the chair.
These and further objects of the invention will become more evident in the following description of a preferred embodiment illustrated in the drawings, wherein:
Fig. l is a perspective view showing the chair set up for use.
Fig. 2 is a section substantially on the line 2-2 of Fig. l on an enlarged scale, with some parts being broken away.
Fig. 3 is a section along the line 33 of Fig. 2, on an enlarged scale, showing a detail of the chair construction. I
Figs. 4 and 5 are enlarged end views showing the seat supporting lever in difierent positions with respect to the seat.
Fig. 6 is a cross-section on the line 6--6 of Fig. 5, showing details of mounting of the seat supporting cross-rod.
. Fig. '7 is a perspective View of the chair in its folded up position.
Referring more particularly to the drawing my improved chair comprises a main frame generally designated at H), and a back frame generally designated at l l. The main frame has two side bars l2, 13 which are connected by the substantially flat cross-bar l4 mounted at the forward endsthereof- Back frame ll comprises two side bars I5, l6 pivotally mounted by bolts on main frame sidebars I2, I 3, respectively. Back frame side bars 15. and I6 are connected by cross bar l8- As clearly shown in Fig. 1, cross bar 18 is secured to the. rearside of side bars 15 and I6 and protrudes a certain distance on both sides thereof for the purpose to be described. Two
.hooked bars 20, 20 are pivotally connected at 2| to respective bars l5, iii of frame H, and preferably consist of flat metal members. Bars 20, 20 each have a slot I9'adapted toengage a bolt 22 provided at the. rear end of frame side bars 12, I3.
' Cross rod 24 extends between back frame side bars [5, l6 and is arranged at some distance above mainframe I 0 so that the seat section supported thereby may be situated above ground. ,Since there are no legs on the beach chair of the invention in which main frame Ill rests di-, .rectly on the ground, this factor is important to the comfort of the user.
Two arms 25, 25 are individually pivotally connected at.,23 to main frame side bars l2, I3. The ends of arms 25 support cross rod 25. Two levers 21, 21. are respectively pivoted at 29 on main frame side bars l2, [3, between main frame It and arms 25. Two connecting levers 28, 28 are pivotally mounted at 35 and 3| between arms 25 and levers 21.
A sheet 32 of canvas 01' other suitable flexible materialis'supported by cross rods 24 and 26 to constitute the seat section. Seat 32 is secured on its supporting cross rods 24 and 26 by means of hems or other suitable fastening method. Another sheet 34, which may also consist of'canvas or any other suitable fabric, is fastened or. tacked onto frame side bars [5 and I6, as indicated at 35 in Fig. '7.
The manner of pivotally mounting back frame I I on main frame It is shown in Fig. 3. A spacer ring 36 is provided between main frame side bar I3 and back frame bar I6. Another spacer 36 is arranged between main frame side bar I2 and back frame bar I5. Each of the rings 36, 36 is faced with two metal washers 31, 31 to reduce the bearing friction. This arrangement enables the housing of bars 20, as well as levers 21, between back frame II and main frame In when the chair is folded up.
Each of the levers 27, 21 has a projecting arcshaped end portion 40 as clearly shown in Figs. 4 and 5. As shown more particularly in Fig. 6, seat supporting cross rod 26 is secured to pivotal arms 25 by means of a counter-sunk screw 4I.
Protective metal rings 42 are secured at the endsof cross rod 26. When the arms 25, 25 are swung in a counterclockwise direction from the foldedup position or from the semi-folded position of Fig. 5, to the set-up position of Fig. 4, the end portion 40 of each lever 21 bears against its associated ring 42 on cross rod 26. The position of Fig. 4 corresponds to the chair as set-up ready for use.
The weight of the person seated on seat 32 tends .to pull cross rod 26 toward back frame I I. Arms 25 are prevented to rotate further in the counterclockwise direction by the supporting and abutting action of levers, 21, 21. At the same time, opposite cross rod 24 is impelled to the right, in the direction towards the front of the seat. This pull is taken up by links 20, 20 hooked onto bolts 22,. '22 in the frame Ill. Thus, links 20, 20 and levers 21, 21 support the seat of the chair in the set-up position of Fig. 1, against the weight of a person seated thereon.
In order to fold the beach chair, links 26, 2 are unhooked from bolts 22, and back frame I I is swung in a clockwise direction until it is flush with main frame I0. Links 20, 26 are then respectively located between side bars I2, l and side bars I3, I6. Cross rod 26 is then rotated in a clockwise direction until it presses against main frame cross bar I4, as shown in Fig. 7. Cross bar I4 thus serves as a stop for cross rod 26. Levers 2I follow arms 25 due to their interconnection by links 28.
Levers 21 are thereupon arranged between main frame side bar I2 and back frame side bar I5, as well as between main frame side bar I3 and back frame side bar I6. The protruding portion of back frame cross bar I8 presses against the upper surface of main frame side bars I2 and I3, thus preventing further rotation thereof. The length of back frame I I is such that, when folded, back frame cross bar I8 does not extend as far as seat supporting cross rod 26.
The back frame II, as well as seat supporting cross rod 26 with its arms 25 and levers 21 are thus housed well within main frame I I], in the folded up position of the chair. The combined thickness of an arm 25, a lever 21 and an associated connecting member 28 does not exceed the thickness of one spacer ring 36. Either of the two cross bars I4 and I8 may be used to grip the folded chair for carrying. By pressing cross bar I8 against main frame side bars I2 and I3, unfolding of the chair is prevented.
Various changes and modifications may be made to the details of construction of the invention without departing from the broader spirit and scope thereof, as set forth in the following claims.
I claim:
