Abstract
A foot rest for a reclining beach chair or lounger having either 1-piece or 2-piece fabric seat liner constructions, including a pair of forwardly extending tubular arms fastened to front pad connectors of such casual seating, and secured together along their lengths in defining the foot rest which receives the fabric liner constructions.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to casual seating, in general, and to collapsible reclining loungers, patio chairs and cots, in particular.
2. Description of the Related Art
Folding or collapsible chairs in the nature of furniture have been described in such U.S. Pat. No. 3,635,520 (Roher et al) and U.S. Pat. No. 5,984,406 (Lee). In a multiple seat arrangement, they are also described in U.S. Pat. No. 5,570,928 (Staunton et al). For outdoor use, in camping and watching sports games, chairs of this type have been illustrated in U.S. Pat. No. 5,893,605 (Chang). When a reclining chair is desired for camping, hiking, fishing, and concert events, a construction,of the type shown in U.S. Pat. No. 5,882,068 (Levine) is said to be useful.
While chairs of these types may prove adequate to suit their intended purposes, they have proven deficient when employed at beaches or seashore locations where users prefer low seat heights, typically no more than 6″ to 10″ above ground. While adjustments for multiple reclining positions in these chairs are highly desirable, the need for adjusting the position safely and easily is equally as important. As the reclining chair is oftentimes left unoccupied when open, it is almost as important, if not more so, for the beach chair to have a degree of stability about it, so as to limit its propensity to be blown about by wind gusts, as well as when being sat upon by a user. These various features, however, are not readily available with the type of folding lounge chair arrangements that typify the prior art—whether the folding lounger is used at the beach, at the seashore, or just in one's backyard.
At the same time, where simply used as a non-reclining patio chair, the acceptability of a folding chair depends in large part upon its strength and reliability of operation. In these two areas, the folding chair of the Lee Patent (U.S. Pat. No. 5,984,406) falls somewhat short.
To address these limitations, therefore, I have invented a new and improved recliner lounge and a new and improved patio chair. The lounge chair, described in an Application filed Apr. 18, 2000, entitled “Collapsible Reclining Beach Chair” (Ser. No.
09/551,664),
now U.S. Pat. No. 6,179,374, incorporates a frame having pairs of crossed front, rear and side legs, with each leg including a pair of bends in opposing directions to allow bringing the seat level of the chair closer to the ground, and with connectors for the legs and a tilt-locking mechanism for stabilizing the chair and positively fixing it at the reclining angle set when opened or folded—and for collapsing the chair to a compact package when closed.
My second improvement, on the other hand, described in application Ser. No. 09/561,339, filed Apr. 28, 2000, and entitled “Collapsible Patio Chair” (now, U.S. Pat. No. 6,322,138), describes a patio chair incorporating a frame having left and right hand rests and pairs of crossed front, rear and side legs, and with connectors for stabilizing the chair when opened and for collapsing the chair to a compact package when closed. With front pad and rear pad connectors, and with rear connectors all being configured with generally perpendicular walls to apertures of which upper and lower ends of both rear legs and one side leg are pivotally connected, the hand rests are automatically folded as the chair is being collapsed, when front connectors employed include a notch within which the upper end of both front crossed legs are arranged to glide in forming the support for the hand rests, and to which an upper end of the other side leg is also pivotally connected.
I have also gone further in this area of casual seating to invent a new and improved collapsible cot, which can easily be carried about, and which is far lighter in weight than conventional cots and hammocks employed at a backyard setting, whose bulky frame typically stays outdoors the whole season, exposed to the elements. Such cot, also automatically folded as the cot is being collapsed, is described in my Application Serial No. 09/593,938, filed Jun. 15, 2000, entitled “Collapsible Cot” (now U.S. Pat. No. 6,364,410).
As will become clear from the following description, the present invention relates to these areas of casual seating, but more particularly, relates to pillows, cooler/utility bags and cup holders employable with any and all of these reclining loungers, patio chairs and cots of my improved designs—with the pillows, cooler/utility bags and cup holders being characterized by themselves being collapsible, so as to be folded when either the lounger, the patio chair, or the cot with which they are used is being collapsed to their individual compact package. As will also be seen, other aspects relate to arm rests and foot rests available with individual ones of these casual seating arrangements.
SUMMARY OF THE INVENTION
As will become clear from the following description, the reclining beach chair or lounger of application Ser. No. 09/551,664, U.S. Pat. No. 6,179,374 with which the collapsible pillow, cooler/utility bag and cup holder of the present invention is particularly useful, replaces the straight leg “X” tubing which characterizes standard designs by an “X” shape tubing incorporating pairs of bends to allow for bringing the seat level of the chair closer to the ground. By replacing the oftentimes used “brake lock” (for free-hand adjustment in sliding the chair back to the desired incline position) with a “positive” slide lock in which a “snap” is secured within a capturing aperture, a true, predetermined locking position results once the recline is set. As will be further described, to increase stability, the reclining lounger is constructed to effectively push forward its center of gravity, as by making the rear legs of the chair longer than the front legs. Where desired, a bar can also be fixed between opposing left and right sides of the chair frame back to further stabilize the chair when extended to an open position. In accordance with its invention, both the chair and the stabilizer bar are easily collapsible into a compact package to facilitate the carrying about and storage of this recliner.
The collapsible patio chair of application Ser. No. 09/561,339, U.S. Pat. No. 6,322,138, on the other hand, consists of a frame including pairs of front crossed legs and rear crossed legs, and two pairs of side crossed legs, with each pair of crossed legs being pivotally connected together where they cross; first and second front pad connectors pivotally connected to lower ends of one of the front crossed legs and one of the side crossed legs, respectively; first and second rear pad connectors pivotally connected to lower ends of one of the rear crossed legs and the other of the side crossed legs, respectively; first and second front connectors pivotally connected to upper ends of the one front crossed leg and the other of the side crossed legs, respectively; first and second rear connectors pivotally connected to upper ends of the rear crossed legs and the one side crossed leg, respectively; a pair of side supports passing through apertures in each of the first and second rear connectors having lower ends fixedly connected to the rear pad connectors; and a fabric liner connected to the first and second front connectors and to upper ends of the pair of side supports.
In accordance with this patio chair invention, to provide strength and reliability of operation beyond that characterizing the patented Lee design, the front connectors include a top surface having a notch therein open at one end and slightly larger than the diameter of the front crossed legs when composed as a tubular configuration, a first wall at an underside thereof defining one side of the notch and to which the upper ends of the front crossed legs are pivotally connected and a second wall at the underside, generally perpendicular to the first wall and combined therewith, to which the upper ends of the other of the side crossed legs are also pivotally connected. In like manner, each of the front and rear connector pads (as well as the rear connectors) include the two generally perpendicular walls for fastening with their respective pivotally connected legs—while the rear connector pads include apertures at the join of the two walls where the side supports are fixed.
The collapsible cot of application Ser. No. 09/593,938, U.S. Pat. No. 6,364,410, furthermore, consists of a frame including two pairs of front crossed legs, two pairs of rear crossed legs, and three pairs of side crossed legs, with each pair of crossed legs being pivotally connected together where they cross. First, second and third front pad connectors are included to pivotally connect to lower ends of the front crossed legs and to individual ones of the side crossed legs—while first, second and third rear pad connectors pivotally connect to lower ends of the rear crossed legs and to individual ones of others of the side crossed legs. First, second and third front connectors pivotally connect to upper ends of the front crossed legs and to individual ones of the side crossed legs, while first, second and third rear connectors pivotally connect to upper ends of the rear crossed legs and to individual ones of others of the side crossed legs. A fabric liner is included connected to two of the front connectors and to two of the rear connectors—and, in completing a preferred construction, a pair of side extenders are pivotally coupled to one of the front crossed legs and to one of the rear crossed legs, where they are joined with the fabric liner for a user to rest upon.
In accordance with this collapsible cot invention, to provide strength and reliability of operation, the front connectors where the two side extenders couple include a top surface having a notch therein open at one end and slightly larger than the diameter of the crossed legs when composed as a tubular configuration, a first wall at an underside thereof defining one side of the notch and to which the upper ends of the crossed legs are connected, along with a second wall at the underside, generally perpendicular to the first wall and combined therewith, to which the upper ends of the others of the crossed legs are also pivotally connected. In like manner, each of the remaining pad connectors include the two generally perpendicular walls for fastening with their respective pivotally connected legs.
In one embodiment of the collapsible cot invention, the side extenders are each pivotally coupled to their associated front crossed leg and to their rear crossed leg at a point below the connector which joins them, whereas in a second embodiment, the sides extenders are pivotally coupled at a point above the connectors. In this first embodiment, various taps, fasteners, and overlying rings are employed to align the crossed legs and extenders together, and to secure them in position; in the second embodiment, hinges are employed to achieve this comparable result.
As will become clear from the following description, the pillow, cooler/utility-bag and cupholder of the present invention cooperates with each of these recliner loungers, patio chairs and cots so as to be usable and collapsible, and to fold with each of them as they are each being collapsed to their respective compact package. When enlarged with the arm rest and/or foot rest for the recliner lounger, a particularly attractive type of casual seating can be had.

DETAILED DESCRIPTION OF THE INVENTION
A. Ser. No. 09/551,664, U.S. Pat. No. 6,179,374, Collapsible Reclining Beach Chair
As with the folding chair of U.S. Pat. No. 5,984,406, the collapsible reclining beach chair or lounger of the application Ser. No. 09/551,664, U.S. Pat. No. 6,179,374 invention is constructed out of tubular members. In
FIG. 1
, the frame of the beach chair
10
includes eight crossed legs in pairs of two each—front legs
12
,
14
, rear legs
16
,
18
, and side legs
20
,
22
and
24
,
26
. As illustrated, each of the pairs
12
&
14
,
16
&
18
,
20
&
22
and
24
&
26
are joined together by pivot pins
25
. The frame
10
, furthermore, includes a pair of side supports
28
,
30
—which, like the crossed legs
12
&
14
,
16
&
18
,
22
and
24
are tubular, and are constructed of aluminum or steel. The side legs
20
and
26
, on the other hand, are constructed of extruded aluminum tubing, the reason for which is explained below.
A pair of front connectors
35
join the crossed legs
14
&
20
and
12
&
26
together at their upper ends. A pair of front pad connectors
40
join the crossed legs
12
&
22
together, as well as the crossed legs
14
&
24
, at their bottom ends. Similarly, two rear connectors
45
,
50
respectively connect the upper ends of crossed legs
16
&
22
and
18
&
24
at their upper ends. Two rear pad connectors
55
,
60
respectively join the lower ends of the crossed legs
18
&
20
and
16
&
26
. As shown in
FIGS. 1-3
, the side supports
28
,
30
respectively extend downwardly through apertures
33
, in the rear connectors
45
,
50
, to couple with a sliding lock mechanism
37
arranged to move linearly along the legs
20
and
26
. As will be described below, the position of the lock mechanism along the legs
20
,
26
sets the angle of recline of the chair frame
10
, where it is positively secured in place.
As illustrated in
FIGS. 16A & 16B
, the cross leg members
12
(also
16
,
20
,
24
) and
14
(also
18
,
22
,
26
) are fabricated with a pair of opposing “bends” at
17
,
19
rather than being of “straight” length as are the legs of U.S. Pat. No. 5,984,406. An aperture
27
is provided mid-way between the bends
17
,
19
to receive the pivot pin
25
(FIG.
17
). Additional apertures
29
,
31
,
39
and
41
receive rivets or similar such fasteners in coupling the crossed legs
12
&
14
,
16
&
18
,
20
&
22
and
24
&
26
to the various connectors
35
,
40
,
45
,
55
and
60
of FIG.
1
.
In particular, the lower end
101
of the crossed legs
12
&
14
are fastened by rivet or other appropriate manner to the front wall
77
of the front pad connector
40
shown as having a perpendicular side wall
78
(FIG.
7
A), the fastener passing through its aperture
79
A. Similarly, the lower end
102
of the crossed legs
22
&
24
also are riveted, or otherwise fastened, to the perpendicular wall
78
, by means of its aperture
79
B. As illustrated, both front pad connectors
40
are identical, with one of the lower ends
101
being on one side of the front wall
77
, the other lower end being on the opposite side, and with the two lower ends
102
being on opposing faces of the side wall
78
.
In like manner, the lower end
103
of the crossed legs
18
&
20
and the lower end
104
of the crossed legs
16
&
26
are fastened by rivets, or otherwise, to the rear pad connectors
55
,
60
respectively, with the rear pad connector
55
being shown in
FIGS. 9A & 9B
, and with the rear pad connector
60
being shown in
FIGS. 10A & 10B
. Each of the connectors
55
,
60
similarly include a pair of perpendicular walls
81
,
82
and
83
,
84
, each with their own apertures
85
A &
85
B and
86
A &
86
B. As indicated, the lower end
103
of leg
20
is fastened to one side of the wall
81
via aperture
85
A while the lower end
103
of leg
18
is fastened to one side of the wall
82
via aperture
85
B. Correspondingly, the lower end
104
of leg
26
is fastened to the opposing surface of wall
83
of connector
60
via aperture
86
B, while the lower end
104
of leg
16
is fastened to the opposing surface of wall
84
via aperture
86
A.
In accordance with the teachings of this reclining beach chair or lounger Application, the dimension L
1
(
FIGS. 9B & 10B
) between the front and rear surfaces of the connectors
55
and
60
is greater than the dimension L
2
(
FIG. 7B
) between the front and rear surfaces of the connector
40
(a diameter in the embodiment of
FIGS. 7A & 7B
) so as to effectively move the center of gravity of the frame
10
forward. This provides a greater stability to the reclining beach chair, a safety feature. Also to enhance stability and safety, a plurality of spaced, compressible pins
91
are included along the lower portion of legs
20
and
26
for fitting within the sliding lock mechanism
37
(FIGS.
8
A and
8
B). An aperture
92
in mechanism
37
receives the lower portion of the leg, with a second aperture
93
available to accept and capture the pin
91
by snap action to form a positive locking securement. A tab
94
, of any desired cross-section, runs along the length of aperture
92
from front to back so as to slide within a linear groove
95
cut along the lower portion of legs
20
and
26
to secure and lock legs
20
,
26
against sideways rotation—with the legs fabricated of extruded aluminum, which can be formed with the linear groove
95
as part of the extrusion. As will be appreciated, it is not generally an easy matter to make steel tubing with the groove
95
as required.
The upper end
111
of leg
20
and the upper end
113
of leg
14
are fastened together in front connector
35
in manner identical to the fastening in connector
32
of upper end
115
of leg
12
and upper end
117
of leg
26
. The connectors
35
are illustrated in
FIGS. 6A & 6B
with one of the legs (
20
or
12
) being fastened through the apertures
121
A and
121
B of two parallel walls
122
,
123
, and with the other of the legs (
14
or
26
) being fastened through the aperture
124
of the perpendicular wall
125
. The aperture
126
will be understood as receiving a screw or like fastener extending upwardly through the connector
35
to join with a cap
130
which holds the fabric liner
131
of the chair in place along the front of the seat (FIG.
5
).
The upper end
141
of the leg
22
is similarly coupled with the upper end
142
of leg
16
within the connector
45
, designed as a mirror image of the connector
50
which receives the upper end
143
of leg
18
and the upper end
144
of leg
24
. These connectors
45
and
50
are illustrated in
FIGS. 12A & 12B
and
11
A &
11
B, respectively, with one leg fastened through each aperture
145
,
146
of the perpendicular walls
147
,
148
, and with the aperture
149
corresponding to the aperture
33
in the connectors
45
and
50
of FIG.
1
.
As illustrated in
FIG. 1
, to complete the basic frame
10
of the reclining beach chair or lounger, the side supports
28
and
30
pass through the aperture
33
in the connectors
45
and
50
to fasten by rivets or otherwise to the slide locking mechanism
37
, and more particularly between the apertures
151
—
151
or
152
—
152
—as illustrated in
FIGS. 8A & 8B
.
FIG. 5
illustrates the manner of attaching the fabric liner
131
to the chair frame
10
. As previously mentioned, a cap
130
secures the front of the liner to the front of the frame. A strap
132
is sewn at left and right undersides
133
of the fabric liner
131
, and is provided with an opening defined by a grommet (not shown), through which the side supports
28
,
30
pass. A sleeve
134
is included at the rear underside of the fabric liner
131
, to slip over the top
135
of the side supports
28
,
30
, reinforced in any desired manner. As shown, the strap
132
rests atop the rear connectors
45
,
50
.
With the frame
10
incorporating a pair of bends
17
,
19
spaced about the pivot point
27
, the seat level of the chair can be brought lower to the ground, to as low as six inches above it, as many users at a beach or seashore location (or just even on a backyard deck, or on the grass) prefer. By providing a slide locking mechanism
37
along the legs
20
and
26
, the beach chair or lounger can be reclined to the desired angle, and with the snap provided through the multiple push pin positions with its capturing aperture
93
, a secure lock at the desired position results. By making the rear pad connectors
55
,
60
longer than the front pad connectors
40
, further increased stability follows. With the position locking arrangements typifying the prior art, freeways rotational turning of the frame was experienced because of the “roundness” of the tubing employed in the lock—a possibility which is virtually eliminated through the scoring of the cross legs
20
and
26
at the groove
95
, in receiving the tab
94
of the snap lock
37
. In a preferred construction, the bends
17
,
19
extend on either side of the pivot pins
25
a distance of 2 to 4 inches, depending upon how low to the ground the seat level of the frame
10
is to go. At the same time, the position to which the recline is set is adjustable either before or after the chair is opened.
While the reclining beach chair or lounger as so far described performs quite well, a further feature of the design offers even greater stability in windy conditions, through the use of a bar
160
hinged between the supports
28
,
30
. Shown in
FIG. 1
, such bar
160
may be of a 2-piece tubular fabrication, fitted at one end “A” onto a rotatable extension
161
of a roller hinge
162
(
FIGS. 14A & 14B
showing the limits of rotation). At the opposite end “B” of the bar fabrication, a hinged bracket
163
is provided with its own rotatable extension
164
to fit within the tubular length (
FIGS. 15A & 15B
illustrating the rotational limits of this hinge). As shown in
FIGS. 1
,
13
A and
13
B, one rotatable extension
164
on each hinge
163
fits within an opening
165
in a coupler
166
, a second opening
167
of which goes over the upper end
171
of the side supports
28
,
30
, where it is held by a press fit. When fabricating the bar
160
of aluminum or other stiffening material, not only is back support provided for the fabric of the chair, but stability of the side supports
28
,
30
is present against ensuing wind.
FIG. 3
illustrates the first step in collapsing the reclining beach chair after use, where the stabilizer bar
160
is employed. Namely, the roller hinge
162
is lifted upwardly, as shown by the arrow
200
, which exerts a pressure on the side supports
28
,
30
, in the direction of the arrows
201
pulling the supports toward each other. The motion rotates the locking mechanisms and the various legs and connectors inwardly, to take on the compact configuration of FIG.
4
. Such action raises the rear connectors
45
and
50
, to lift the fabric liner
131
which rests thereon, to collapse it as well, wherein the beach chair or lounger, then in a collapsed condition, can be placed in a duffle bag and carried about, or otherwise stored. Where the stabilizer bar
160
is not employed, only a gentle pressure on the supports
28
,
30
in the direction of the arrows
201
is all that is necessary to begin the collapsing action.
As my application Ser. No. 09/551,664, U.S. Pat. No. 6,179,374 describes, whereas compressible pins
91
are set out to snap the slide lock mechanism
37
in secured position, other manners of fastening the mechanism in place can be utilized instead—such as by a lever and actuating spring into the extruded tubing.
B. Ser. No. 09/561,339, U.S. Pat. No. 6,322,138, Collapsible Patio Chair
As with the folding chair of U.S. Pat. No. 5,984,406, the collapsible patio chair of the application Ser. No. 09/561,339, U.S. Pat. No. 6,322,138 invention is also constructed out of tubular members. In
FIG. 18
, the frame of the patio chair
210
includes eight crossed legs in pairs of two each—front legs
212
,
214
, rear legs
216
,
218
, and side legs
220
,
222
and
224
,
226
. As illustrated, each of the pairs
212
&
214
,
216
&
218
,
220
&
222
and
224
&
226
are joined together by pivot pins
225
. The frame
210
, furthermore, includes a pair of side supports
228
,
230
—which, like the crossed legs
212
&
214
,
216
&
218
,
220
&
222
and
224
&
226
are tubular, and are constructed of aluminum or steel.
A pair of front connectors
235
join the crossed legs
214
&
220
and
212
&
226
together at their upper ends. A pair of front pad connectors
240
join the crossed legs
212
&
222
together, as well as the crossed legs
214
&
224
, at their bottom ends. Similarly, two rear connectors
245
,
250
respectively connect the upper ends of crossed legs
216
&
222
and
218
&
224
at their upper ends. Two rear pad connectors
255
,
260
respectively join the lower ends of the crossed legs
218
&
220
and
216
&
226
. As shown in
FIGS. 18-20
, the side supports
228
,
230
respectively extend downwardly through apertures
233
, in the rear connectors
245
,
250
, to fix with the rear pad connectors
255
and
260
without pivoting. With the patio chair constructed with hand rests, each front leg
212
,
214
is provided with an extension
265
that extends upwardly through the front connectors
235
and bends outwardly to form a front support
266
where it is secured, as by a screw, with a sleeve at a front underside of a fabric hand rest (
215
, in FIG.
21
), at the rear of which a grommet
267
on the fabric encircles the side supports
228
,
230
, and where it is restricted in upwards movement by a ring
268
on the supports
228
,
230
. As with the hand rests of U.S. Pat. No. 5,984,406, the hand rest
215
provides a support for the user's arm, as well as a manner to fold and unfold the chair with adequate leverage.
Particularly referring to
FIGS. 18
,
19
,
24
A &
24
B, and
25
A &
25
B, the lower end
301
of the crossed legs
212
&
214
are fastened by rivet or other pivot manner to the front wall
284
of the front pad connector
240
shown as having a generally perpendicular side wall
283
, the fastener passing through its aperture
286
A. Similarly, the lower end
302
of the crossed legs
222
&
224
is also fastened by rivet, or other pivot to the wall
283
, by means of its aperture
286
B. As illustrated, both front pad connectors
240
are identical, with one of the lower ends
301
being pivoted on one surface of the front wall
284
, with the other one of the lower ends
301
being on the opposite surface of the front wall
284
, and with the two lower ends
302
being pivoted on opposing faces of the side wall
283
.
In like manner, the lower end
303
of the crossed legs
218
&
220
and the lower end
304
of the crossed legs
216
&
226
are fastened by rivets, or other pivots to the rear pad connectors
255
,
260
respectively, with the rear pad connector
255
being of the configuration shown in
FIGS. 25A & 25B
, and with the rear pad connector
260
being of the configuration shown in
FIGS. 25A & 25B
rotated 90° counterclockwise. Each of the connectors
255
,
260
thus include their own pairs of generally perpendicular walls and their own apertures. As indicated, the lower end
303
of leg
220
is fastened by pivot or otherwise to rear pad connector
255
at one surface of the wall
284
via aperture
286
A while the lower end
303
of leg
218
is fastened by pivot or otherwise to one surface of the wall
283
via aperture
286
B. Correspondingly, the lower end
304
of leg
226
is fastened to the opposing surface of wall
284
of connector
260
via aperture
286
A, while the lower end
304
of leg
216
is fastened to the opposing surface of wall
283
via aperture
286
B. In accordance with the invention, apertures
287
are included at the joins
288
of the walls
283
,
284
of the connectors
255
,
260
to receive the lower ends of the side supports
228
,
230
, where they are fixed by rivets or otherwise, without pivoting. Although not receiving side supports, the front pad connectors
240
may be constructed with a similar aperture
287
at the joins
288
of their walls
283
,
284
, to allow for a common construction of these front and rear pad connectors and an interchangeability of components, although such apertures
287
at the front pad connectors are not needed for operation of the collapsible patio chair.
The upper end
311
of leg
220
and the upper end
313
of leg
214
are fastened together in front connector
235
in manner identical to the fastening in connector
35
of upper end
315
of leg
212
and upper end
317
of leg
226
. The connectors
235
are illustrated in
FIGS. 22A & 22B
and
23
A &
23
B—with the configurations of
FIGS. 22A & 22B
receiving the legs
212
and
226
, and with the configuration of
FIGS. 23A and 23B
receiving the legs
214
and
220
. As shown, the connectors
235
include a top surface
290
having a notch therein
291
open at one end, understood to be slightly larger than the diameter of the crossed legs
212
,
214
when composed as a tubular configuration. This dimensioning allows the legs
212
,
214
to glide easily within the notch
291
as the patio chair is folded closed or opened. As more particularly shown in
FIGS. 22B and 23B
, the front connectors
235
further include a first wall
292
at an underside defining one side of the notch
291
and to which the legs
214
and
212
are fastened. At the same time, the connectors
235
include a second wall
293
at the underside, generally perpendicular to the wall
292
in combination therewith, to which the upper ends
311
and
317
of the crossed legs
220
and
226
are fastened. In similar manner, both perpendicular walls
292
,
293
are provided with apertures
295
,
296
for fastening with their respective pivotally connected legs.
The upper end
341
of the leg
222
is similarly coupled with the upper end
342
of leg
216
within the connector
245
, designed as a mirror image of the connector
250
which receives the upper end
343
of leg
218
and the upper end
344
of leg
224
. These connectors
245
and
250
are illustrated in
FIGS. 26A & 26B
and
27
A &
27
B respectively, with one leg fastened through each aperture
345
and
346
of the perpendicular walls
347
and
348
as shown, and with the aperture
349
corresponding to the aperture
233
in the connectors
245
and
250
of FIG.
18
through which the side supports
228
,
230
pass.
FIG. 21
illustrates the manner of attaching the fabric liner
331
to the chair frame
210
. A sleeve at an underside of the liner front
332
is pulled down once installed at A to fit over the front connectors
235
. A strap
333
is sewn at left and right undersides
334
of the fabric liner
331
, and is provided with an opening defined by a grommet
335
through which the side supports
228
,
230
pass. As shown, the strap
333
rests atop the rear connectors
245
,
250
, and its upward movement is restricted by a second ring
269
on the side supports
228
,
230
. Sleeves are also included at the rear underside of the fabric liner
331
, adjacent its top, to slip over the top
336
of the supports
228
,
230
(where they are secured as by a screw), with all areas of connection of the fabric liner being reinforced in any desired manner.
To collapse the opened chair of
FIG. 18
, all that is needed is for one to grasp onto the upper bends
265
of the legs
212
,
214
, and push them towards one another. The legs
212
,
214
readily slide within the notch
291
, and the pivot connections of all the legs to opposing faces of the perpendicular walls reliably collapses the frame
210
to the compact configuration of FIG.
20
. Then, in a collapsed condition, the patio chair can be placed in a duffle bag and carried out, or otherwise stored. As will be appreciated, the collapsing of the chair to the configuration of
FIG. 20
will be understood to fold the fabric hand rest
215
upwardly and out of the way at the same time.
C. Ser. No. 09/593,938, U.S. Pat. No. 6,364,410, Collapsible Cot

434
, and a third pair of side crossed legs
436
,
438
. As illustrated, each of the pairs
412
&
414
,
416
&
418
,
420
&
422
,
424
&
426
,
428
&
430
,
432
&
434
, and
436
&
438
are joined together by pivot pins
425
.
A first front pad connector
440
pivotally connects to lower ends of the front crossed leg
412
and the side crossed leg
428
, while a second front pad connector
442
pivotally connects to lower ends of the front crossed leg
418
and the side crossed leg
432
. A first rear pad connector
444
pivotally connects to the lower ends of the rear crossed leg
420
and the side crossed leg
430

416
and to the upper end of the side crossed leg
434
. A first rear connector
452
pivotally connects to the upper ends of the rear crossed leg
422
and the side crossed leg
428
, while a second rear connector
454
pivotally connects at an upper length of the rear crossed leg
424
and to the upper end of the side crossed leg
432
.
In accordance with the construction of the collapsible cot, a third front pad connector
456
is included, pivotally connected to the lower ends of the front crossed legs
414
&
416
and to the lower end of the side crossed leg
436
. A third rear pad connector
458
similarly is pivotally connected to the lower ends of the rear crossed legs
422
&
424
, and to the lower end of the side crossed leg
438
. A third front connector
460
pivotally connects to upper ends of the front crossed legs
412
&
418
, and to the upper end of the side crossed leg
438
. A third rear connector
462
then pivotally connects to the upper ends of the rear crossed legs
420
&
426
, and to the upper end of the side crossed leg
436
.
To complete the configuration of the frame
410
, a first side extender
470
pivotally couples to the front crossed leg
416
along its upper length, while a second side extender
472
pivotally couples to the rear crossed leg
424
along its respective own upper length.
As illustrated in
FIG. 37
, a fabric liner
500
is connected to the front connectors
448
and
460
and to the rear connectors
452
and
462
and to fit over and around the upper ends A, B, of the side extenders
470
,
472
—both for this construction of the cot and for a second construction to be described below.
In
FIG. 28
, the side extenders
470
,
472
are shown pivotally coupled to the front crossed leg
416
and to the rear crossed leg
424
at a point above the second front connector
450
and the second rear connector
454
, respectively.
FIGS. 29A-29F
illustrate the pivotal coupling of the two side extenders
470
,
472
to their respective front and rear crossed legs
416
,
424
by means of a hinge pin
490
,
492
, for example, in the manner noted in
FIGS. 29A-29C
, and rotatable from its open position of FIG.
29
D through its immediate position shown in
FIG. 29E
to its folded position of
FIG. 29F
, when it is desired to collapse the frame
410
of the cot. The end of the extenders
470
,
472
to which the fabric liner
500
secures when in place is again indicated at A, B.
FIGS. 38A-38C
in this respect illustrate sectional views of a manner of securing the fabric liner
500
to the front connectors
448
,
460
and to the rear connectors
452
,
462
, by means of a bolt
501
, for example, extending through apertures
575
in the liner
500
overlying each of the four connectors at such point, to seat within a cap
502
which fits substantially flat there against the top surface of the liner
500
.
FIG. 35
, on the other hand, shows an alternative construction in which the side extenders
470
,
472
are each pivotally coupled to the front crossed leg
416
and to the rear crossed leg
424
at a point below the second front connector
450
and below the second rear connector
454
, respectively, instead of above those connectors as in FIG.
28
. As shown in FIGS.
36
A and
36
B, the construction of
FIG. 35
is one in which a first bracket
484
is included at a point below the second front connector
450
while a similar second bracket
486
is included at a point below the second rear connector
454
. As illustrated more particularly in
FIG. 36B
, the two side extenders (
470
on the one hand, and
472
on the other), are pivotally coupled to the brackets
484
,
486
, by a pin
435
to permit the pivoting of the side extenders
470
,
472
, about both the front crossed leg
416
and the rear crossed leg
424
. Each of the brackets
484
,
486
typically may be composed of steel, welded to the crossed leg
416
(or
424
as the case may be), to receive and join with the respective extender
470
,
472
. As
FIGS. 36A and 36B
further show, a first tap
480
is provided along the upper length of the front crossed leg
416
while a second such tap
482
is provided along the upper length of the rear crossed leg
424
, to allow for positioning of the side extenders
470
and
472
, respectively, in fixing the position of the side extender with its respective crossed leg.
FIG. 36B
further shows a fastener
488
at left and right undersides of the fabric
500
, near its top end, at a position to overlie the side extender and its adjacent crossed leg, for securing the respective extender and leg together. Thus, those points labelled C and D in
FIG. 35
illustrate the locations where the fasteners
488
of the fabric
500
secure in holding the side extender
470
to the crossed leg
416
and the side extender
472
to the crossed leg
424
—with the fastener
488
being in the form of a steel ring when the crossed legs
416
,
424
and the side extenders
470
,
472
are tubular.
FIG. 37
, in this respect, shows this alternative construction with the fabric liner
500
.
Particularly referring to
FIGS. 28
,
35
,
37
,
30
A &
30
B, the lower end of the front crossed legs
412
&
418
are fastened by rivet or other pivot manner to the front wall
510
of the front pad connectors
440
,
442
, shown as having a generally perpendicular side wall
512
, the fastener passing through its aperture
514
. Similarly, the lower end of the side crossed legs
428
&
432
is also fastened by rivet or other pivot to the wall
512
by means of its aperture
516
. As illustrated, both front pad connectors
440
,
442
are identical, with the lower end of the front crossed leg
412
being pivoted on one surface of the front wall
510
on one connector
440
,
442
, with the lower end of the front crossed leg
18
being on the opposite surface of the front wall
510
of the other connector
440
,
442
, and with the lower ends of the side crossed legs
428
and
432
being pivoted on opposing faces of the side wall
512
.
In like manner, referring to
FIGS. 28
,
35
,
37
,
32
A &
32
B, the lower end of the rear crossed legs
420
&
426
and the lower ends of the side crossed legs
430
&
434
are fastened by rivets or other pivots to the rear pad connectors
444
,
446
. Each of the connectors
444
,
446
include their own pairs of generally perpendicular walls and their own apertures. Thus, and as indicated, the lower end of the front crossed leg
420
is fastened by pivot or otherwise to rear pad connector
444
at one surface of the wall
511
by aperture
515
while the lower end of leg
426
is fastened by pivot or otherwise to one surface of the wall
513
by aperture
517
. Correspondingly, the lower end of the side crossed leg
430
is fastened to the opposing surface of wall
511
via aperture
515
while the lower end of the side crossed leg
434
is fastened to the opposing surface of wall
513
via aperture
517
. In accordance with the construction, an aperture
518
is included at the joins of the walls
511
&
513
of the connectors
444
,
446
to receive the lower end of the rear supports
464
,
466
, where they are fixed by rivets or otherwise, without pivoting. Although not receiving any supports, the front pad connectors
440
,
442
may be constructed with a similar aperture
519
at the join of their walls
510
&
512
, to allow for a common construction of these front and rear pad connectors and an interchangeability of components, although such apertures
519
at the front pad connectors
440
,
442
are not needed for the operation of the collapsible cot.
As an examination of
FIGS. 28 and 37
will show, the front connector
448
may be constructed identical to the rear connector
452
, except insofar as the rear connector
452
includes an aperture to receive the upper end of the rear support
464
—with the remaining structure of these two connectors continuing to have generally perpendicular side walls to which the upper ends of the front crossed leg
414
and the side crossed leg
430
are pivoted on the one hand with respect to the front connector
448
, and to which the upper ends of the rear crossed leg
422
and the side crossed leg
428
are likewise pivotally connected with respect to the rear connector
452
on the other hand, this is shown in
FIGS. 34A & 34B
where the perpendicular side walls are shown at
547
,
548
, and where the aperture for the support
464
is shown at
549
. The pivot connections for the legs are through the apertures
545
,
546
.
The third front pad connector
456
is similarly constructed comparable to the third front connector
460
in having yet a further perpendicular wall so as to receive three sets of legs instead of the two sets as with the front pad connectors
440
and
442
—pivotally receiving the lower ends of the front crossed legs
414
&
416
and the lower end of the side crossed leg
436
. Correspondingly, the third front connector
460
receives at its three perpendicular walls, the pivot connections of the front crossed legs
412
&
418
and the upper end of the side crossed leg
438
. The third rear connector
462
, on the other hand, includes the same three perpendicular walls to receive, in pivot connections, the upper ends of the rear crossed legs
420
&
426
and the side crossed leg
436
—although with a further aperture to receive the rear support
468
extending up from the rear pad connector
458
. In such manner, the rear pad connector
458
and the rear connector
462
may be mirror images of one another, just as are the front pad connector
456
and the front connector
460
. As will be appreciated, each of the connectors
448
,
452
,
460
and
462
are provided with apertures
475
as indicated in
FIGS. 28 and 35
to receive the bolt
501
and cap
502
of
FIGS. 38A
,
38
B &
38
C in holding the fabric liner
500
in place.
To complete the constructions of the collapsible cot, the upper end of the side crossed leg
432
, is fastened along the upper length of the rear crossed leg
424
on the rear connector
454
in a manner identical to that by which the upper end of the side crossed leg
434
is fastened along the upper length of the front crossed leg
416
in the front connector
450
. Such connectors
450
and
454
are illustrated in
FIGS. 31A & 31B
and
33
A &
33
B, respectively—with the configurations of
FIGS. 31A and 31B
receiving the legs
416
and
434
, and with the configurations of
FIGS. 33A & 33B
receiving the legs
424
and
432
. As shown, the connectors
450
,
454
include a top surface
550
having a notch therein
551
open at one end, understood to be slightly larger than the diameter of the crossed legs
416
,
424
when composed as a tubular configuration. This dimensioning allows the legs
416
,
424
to glide easily within the notch
551
as the cot is folded closed or opened. As more particularly shown in
FIGS. 31B and 33B
, the front connector
450
and the rear connector
454
further include a first wall
552
at an underside defining one side of the notch
551
and to which the legs
416
and
424
are fastened. At the same time, the connectors
450
and
454
include a second wall
553
at the underside, generally perpendicular to the wall
552
in combination therewith, to which the upper ends of the side crossed legs
434
and
432
are fastened. In similar manner, both perpendicular walls
552
and
553
are provided with apertures
554
,
555
for fastening with their respective pivotally connected legs.
To collapse the opened cot of
FIGS. 28 and 35
, all that is needed is for one to push forward the side extenders
470
,
472
, to the upper ends of the front crossed leg
416
and the rear crossed leg
424
. The legs
416
,
424
readily slide within the notch
551
, and the pivot connections of all the legs to opposing faces of the perpendicular walls reliably collapses the frame to a compact configuration. Then, in a collapsed condition, the cot can be simply carried to wherever it may be placed for storage. As will be appreciated, the collapsing of the cot will be understood to fold the fabric liner
500
inwardly and out of the way at the same time, yet without it having to be removed from the side extenders
470
,
472
.
D. Collapsible Constructions of the Present Invention
As was previously mentioned, a particularly attractive type of casual seating can be had for the collapsible reclining beach chair or lounger through the addition of an arm rest and/or a foot rest. By having such rests being collapsible—and by complementing them with pillows and with cooler/utility bags and cup holders which also fold when collapsed with either the lounger, the patio chair, or the cot of my earlier inventions—several constructions result which are quite useful for these types of casual seatings.
1. Collapsible Pillow
With this aspect of the present invention—illustrated in
FIG. 39
, for example, with the collapsible reclining beach chair or lounger of my Ser. No. 09/551,664, U.S. Pat. No. 6,179,374 invention—a pillow
600
hangs over the fabric liner
131
on the front of the lounger when the chair is open, and fits between its side supports
28
,
30
, when the lounger is collapsed (FIG.
40
). As will be appreciated, this becomes possible from the presence of an “empty slot” area
605
in the chair when the lounger is collapsed (FIG.
4
).
To take advantage of such “empty slot” in
FIG. 4
, a first attaching strip
601
is sewn between, or similarly connects as by a “snap-button”, the pillow
600
with the back of the liner
131
, while a second attaching strip
602
is detachably coupled between the pillow
600
and the back of the liner. This allows the pillow
600
to be flipped from the horizontal position shown in
FIG. 39
when in place, to a vertical position within the slot
605
as the reclining lounger is folded. Once flipped to the vertical position, the strip
602
can be reattached about a side support of the lounger when fully collapsed, to then hold the pillow
600
in place once more. In this respect, the attaching strip
601
may be stitched between the pillow
600
and the liner
131
, and the attaching strip
602
may be of a conventional hook-and-loop Velcro adhesive.
The various schematics of
FIGS. 42A-42E
will be helpful in understanding the flipping sequence of the pillow
600
—with the understanding that the placements of the two strips
601
,
602
can just as easily be reversed, side-to-side.
FIG. 41A
, however, first illustratively shows (in simplified form) the lounger when fully collapsed, and
FIG. 41B
illustratively shows the lounger in its opened, reclining position. As will be seen, the width W of the slot
605
when the lounger is collapsed (
FIG. 40
) may be equal to, slightly greater than, or slightly less than, the thickness T of the pillow
600
(FIG.
42
C). Secondly, both attaching strips
601
and
602
may be connected at points equi-distant from the left and right side ends of the pillow
600
, with the strip
601
being of sufficient length to permit its encirclement over and about the side support
30
(see FIG.
40
), and with the length of the strip
602
being selected sufficiently long to enable its re-attachment about the side support
30
in securing the pillow
600
in position once the reclining lounger is collapsed.
Thus,
FIG. 42A
schematically shows the pillow
600
in horizontal position against the liner
131
for the open lounger, with front and rear surfaces A & F, with top and bottom surfaces B & C and with side surfaces D & E, although not drawn to scale. Uncoupling the Velcro strip
602
and rotating the pillow
600
90° upwardly leads to the position of the pillow schematically shown in FIG.
42
B—such that surface A then faces upwardly. Rotating the pillow
600
counterclockwise 90° then, followed by rotating it upwardly 90° from the bottom, leads to the position of the pillow shown in
FIG. 42C
, in which the rear surface F faces forwardly and in which the side surface C faces to the right. Rotating the pillow
600
then a further 90° counterclockwise results in the position schematically shown in
FIG. 42D
, with the pillow
600
in a vertical plane, with the stitched attaching strip
601
at the top looped around the side support
30
, and the detachable strip
602
at the bottom, ready to be connected about the support
30
. The orientation of the pillow
600
is thus in accordance with the collapsed condition of the lounger shown in
FIG. 40
, and with the pillow
600
able to be fitted easily between the supports
28
,
30
when of a thickness less than the distance between the two supports.
(It will be readily appreciated by those skilled in the art that the progression from the position of
FIG. 42A
to that of
FIG. 42D
may be attained through other sequences of rotation than as set forth above. It will also be appreciated that these connections follow an intention to employ as large a pillow as possible for user convenience. In those instances where a smaller dimensioned pillow is to be used, the strips
601
,
602
which couple the pillow
600
to the rear of the fabric liner
131
could each be of a hook-loop Velcro adhesive, to be simply detached from the liner before or as the lounger is being collapsed, to be then simply stowed in the slot
605
which results. The attractiveness of such an alternative arrangement will be understood when one considers trans-shipment of the lounger from manufacturer to ultimate user, by which the smaller pillow could simply be packed in the empty slot
605
and held there in place during transportation. However, for the pillow to automatically fold as the recliner or lounger is collapsed, one of its attaching strips, according to the invention, first requires its detachability. Analysis will also show a similar requirement where the pillow is arranged for the patio chair or cot of my above-noted inventions.)
2. Collapsible Cooler/Utility Bags and Cup Holders
With this aspect of the present invention—illustrated in
FIG. 43
, (once again for example, with the collapsible reclining beach chair or lounger of my Ser. No. 09/551,664, U.S. Pat. No. 6,179,374 invention as shown in FIG.
5
)—a cooler/utility bag
620
is shown, with a cup holder
622
for similar coupling to the fabric liner
131
on the front of the lounger when the chair is open. As will be seen from the description below, furthermore, like the pillow
600
of
FIGS. 39-42
, the cooler/utility bag
620
and the cup holder
622
are themselves foldable with the lounger as it is being collapsed. As will also be seen, as with the pillow, one of their attaching strips is non-detachable at one end to prevent its being lost—although, where desirable, the bag
620
—holder
622
combination also can be fully detachable and stowed in the “empty slot” area
605
of the reclining lounger between the side supports
28
,
30
during shipment. As with the pillow
600
, one of the attachment strips is sewn to the fabric liner
131
, or otherwise connected, although, here, the detachable hook-and-loop Velcro adhesive strip is replaced by a “hook” in the preferred embodiment. And, as
FIG. 43
shows, the fabric liner
131
is modified to include a pair of preferably reinforced apertures
624
,
626
, the first of which (
624
) is located in the “seat” portion of the liner
131
while the second of which (
626
) is located in the “back” portion of the liner.
In particular, the cooler/utility bag
620
—some 11″ long, 5½″ tall and 3″ deep so as to be also used as a “book bag”, for example—is provided with a first hook
628
(detail A, FIG.
44
A), a second hook
630
(detail B,
FIG. 44B
) joined with the aperture
624
(detail C,
FIG. 44C
) and a permanent stitching
632
to the underside of the fabric liner
131
(detail D, FIG.
44
D). As will be appreciated, with a conventional size for a 12 oz can of soda being 2⅝″ diameter and 5″ height, the above dimensions for the cooler/utility bag
620
are sufficient for holding four of these beverage containers.
For the cooler/utility bag
620
to be stored within the same “empty slot”
605
of the lounger where the pillow of
FIGS. 39-42
is fitted, for example, a comparable type of detachment, flipping and twisting procedure is necessitated. Thus, after detaching the hook
630
from the aperture
624
, the cooler/utility bag
620
(with front and rear surfaces A & E, with top and bottom surfaces B & C and with right and left side surfaces D & F) is twisted and rotated as follows:
With the hook
630
released and with the permanent stitching
632
in position (
FIG. 45A
) the cooler/utility bag
620
is rotated upwardly 90° to the position shown in
FIG. 45B
, then rotated vertically and in a counterclockwise direction 90° to the position of
FIG. 45C
, then rotated horizontally 90° counterclockwise to result in the position of FIG.
45
D. The second hook
628
, then being positioned adjacent to the aperture
626
in the fabric liner
131
is inserted to present the overall appearance of FIG.
46
.
As the weight of any cans in the cooler/utility bag
620
or anything in the cup holder
622
would have a tendency to tilt the cooler/utility bag
620
inwardly towards the reclining chair, patio chair or cot in conjunction with which it is to be used, the rear surface of the bag
620
adjacent to its bottom, is provided with a bumper to rest against the side crossed members of the casual seat in “righting” the cooler/utility bag when so loaded. Such bumper is indicated as
640
in FIG.
45
A. For storage, when the bag
620
is not in use, a typical Velcro strip
642
sewn at the rear surface of the bag (
FIG. 45C
) couples to a similar coupling strip
644
at an underside of the seat portion of the fabric liner
131
, to be there held in position (FIG.
43
). Freeing the two strips
642
,
644
then rotates the bag
620
—holder
622
combination to the position shown in FIG.
43
. As will be appreciated, other types of fasteners could alternatively be employed, just as the hooks
624
and
628
could be substituted by other hook and loop adhesives, instead of through the use of the metal or plastic hook constructions envisioned. As with the pillow of
FIGS. 39-42
, the cooler/utility bag
620
(with or without the cup holder
622
) is thus foldable into the casual seat frame as the lounger is being collapsed. A similar analysis will show that the exact same manner of coupling the cooler/utility bag with the fabric liner folds the bag into the empty slot created when the patio chair or cot of my earlier inventions are collapsed.
3. Collapsible Arm Rest
While
FIGS. 18-26
illustrate a very attractive collapsible patio chair embodying my invention, the hand or arm rest shown as
215
, in
FIG. 21
, is of a fixed length. This is the case with all reclining lounge chairs available in the prior art and generally detracts from their reliability of operation. In accordance with this invention, on the other hand, an adjustable length feature typifies the arm rest—such that when the reclining beach chair or lounger is set to its straight-up position, the arm rest will be at its shortest length—whereas, when the lounger is set to its most reclining position, the arm rest will then be at its longest length. Not only is this adjustable length arm rest quite reliable in operation, it has been found to be the most simplest and easiest to use.
In accomplishing this, the reclining beach chair or lounger of
FIG. 1
is modified as respects its front connectors
35
so as to take on the appearance of the front connectors
235
of the collapsible patio chair configuration of FIG.
18
. At the same time, the front legs
12
and
14
of the
FIG. 1
lounger are modified to take on the appearance of the front legs
212
and
224
of the patio chair of
FIG. 18
as respects the upper bends
265
of the legs
212
,
214
in forming the front support
266
for the arm rest. This results in the general appearance of FIG.
47
. As so far described then,
FIG. 48
illustrates the reclining beach chair with the arm rests shown at
650
, with the pillow shown at
600
and with the cooler/utility bag shown at
620
. Reference numeral
622
continues to illustrate the cup holder employed with the cooler/utility bag
620
, while the upper bends of the modified front legs
12
,
14
continue to be shown at
265
.
FIGS. 49 and 50
are views of the reclining lounger of
FIG. 48
in its “straight-up” and most reclining position, respectively (but without the pillow
600
, the cooler/utility bag
620
and the cup holder
622
for purpose of simplicity), while
FIGS. 51
,
52
,
53
and
54
illustrate the adjustable length feature of the arm rest for each of these two positions. More specifically,
FIGS. 51-54
show the arm rest
650
as consisting of two sections, one of which
652
includes an oval aperture
653
and a grommet
654
about the side support
28
,
30
of the lounger, along with a series of spaced slots
655
—illustrated as five in number, and preferably equally spaced in the embodiment depicted. At the rear end of the other section
657
, a clasp in the form of a looped fastener
658
is embedded (FIG.
53
), dimensioned to fit within one of the five slots
655
. In the straight-up position of the reclining lounger of
FIG. 49
, the looped fastener
658
is shown as seated within the far-most slot
655
A, with the remainder of the front section
657
then lying over the unused slots
655
of the rear section
652
, whereas in the most reclining position of
FIG. 50
, the fastener
658
fits within the near-most slot
655
E. As will be appreciated, adjusting the fastener
658
into any one of the slots
655
A-
655
E thereby adjusts the length of the arm rest
650
, in conjunction with the recline afforded to the lounger shown. To facilitate reliability of operation, the aperture
653
is ovate rather than circular, to ease movement of the side support
28
,
30
as the arm rest
650
is being adjusted. For the same reason, the arm rest section
652
is shown with a downwards angular tilt at its rear end in joining with the side support
28
,
30
(FIG.
54
).
(
FIG. 55
illustrates yet a further way of adjusting the length of the arm rest, for a reclining lounger employing a single folded over arm rest
660
, a D-ring
662
, and an S-shaped hook
664
. As illustrated, the D-ring is secured within chamfered surfaces on the side supports
28
,
30
in receiving the arm rest
660
, whose underside section
666
is provided with a loop
668
to receive one end of an S-clip clasp
664
. The other end of the S-clip
664
fits within one of several notches
669
in the arm rest
660
—either pulling the arm rest
660
tighter (thereby shortening the arm rest) as in the position shown, or lengthening it as it is moved rearwardly to the left from aperture to aperture, consistent with increasing the lounger's recline. The reclining beach chair lounger with this adjustable arm length construction is shown in
FIG. 56.
)
4. Collapsible Foot Rest
In certain instances, a user might desire to employ with the reclining beach chair or lounger a foot rest along the lines of an ottoman. To accommodate such desire, the reclining beach chair of
FIG. 1
, or that of
FIG. 47
could be modified still further simply through modification of the front pad connectors
40
. More specifically—and as shown in FIG.
57
—the front pad connectors
40
could be arranged to include a clip
690
to secure by rivet
691
or otherwise, one end
699
of a further tubular member
692
joined with a similar tubular member
693
along its length, as by a rivet
694
. The extending end
695
of the two tubular members
692
,
693
then fit within folds at the forward most end of the fabric seat liner
131
for the lounger.
FIG. 58
illustrates this arrangement for a fabric liner
131
of a 1-piece construction. Where a
2
-piece construction is employed for the liner (
FIG. 59
, upper section
131
A, lower section
131
B), the added section
131
B can be secured about the upper bends
255
of the front legs
212
,
214
by individual ties
696
(where arm rests are employed, or about the front connection
35
where they are excluded [as in FIG.
1
]; or in the event a cap secures the seat liner upper section
131
A to the front connector
35
[as in FIG.
5
], only a tie
696
is needed to secure the lower section
131
B to the connector
35
).
FIG. 60
illustrates a Y-type connector
697
between the arms of which the end
699
of the tubings
692
,
693
are joined, with the Y connector
697
being fastened to the front pad connector
40
by a screw or other bolt connection
698
extending upwardly through the pad connector. With either the 1-piece construction of the liner, or with the 2-piece construction, the reclining beach chair or lounger can be fully collapsed when it is desired to stow or transport the lounger, with the clips
690
allowing the front extenders to rotate upwardly and downwardly in a vertical plane.
While there have been described what are considered to be preferred embodiments of the present invention, it will be appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herein. Thus, whereas the arm rest and foot rest of the invention have been described in the context of the reclining beach chair or lounger of my Ser. No. 09/551,664, U.S. Pat. No. 6,179,374 invention, their teachings will apply equally as well for a reclining beach chair whose lower legs are not bent outwardly so as to rest closer to the ground. And, although the front extender tubular members
692
and
693
of the foot rest are held between the arms of a Y-type connector
697
, a similar U-type connector could equally be employed, continuing to accept the screw or bolt
698
extending upwardly through the front pad
40
, or otherwise extending downwardly through the connector into the pad
40
in yet a further modification. For at least such reason, therefore, resort should be had to the claims appended hereto for a true understanding of the scope of the invention.
