Description
BACKGROUND OF THE INVENTION
1. Field
The invention is in the field of portable collapsing or folding rocking chairs and chaise lounges for use indoors and outdoors such as for camping and which chair may also function as a backpack, cart, wheelchair, or cot.
2. State of the Art
Portable collapsing rocking chairs of the type which have a flexible rectangular seat supported at opposite ends by oppositely inclined, diagonally disposed frames interconnected by a pair of upper and lower chains are well known. The frames of these chairs each typically have a pair of parallel elongate side members interconnected and held in a spaced relationship by at least one cross member, one frame nesting within the other. The pairs of upper and lower chains interconnect the respective side members intermediate the ends thereof to form what is called a saddle hinge which allows the chair to be oscillated or rocked since there is no fixed pivot between the respective frames. Likewise, wheeled carts, and wheeled chairs are well known.
In U.S. Pat. No. 4,118,064 issued to Robeson is disclosed a wooden rocking chair wherein the upper ends of the elongate side members and the ends of cross members of each frame are held together by means of interfitting wedge and groove connections which allow disassembly of the frames so as to form a compact bundle for transport or storage. A stool of similar construction is also disclosed.
In U.S. Pat. No. 1,969,313 issued to C. E. Meeker is disclosed a wooden rocking chair wherein the elongate side members and the cross members of each frame are held together by means of the upper end of each side member being tapered to mate with tubular sockets at the ends of the upper cross members. One frame also has a lower cross member pivotally and releasibly connected at respective ends thereof to the lower portion of one frame such that the chair can be disassembled and the lower cross member folded to form a compact bundle for transport or storage.
In U.S. Pat. No. 4,733,905 issued to Buickerood et al. is disclosed a two-wheeled, non-rocking chair which has four U-shaped tubular metal frame members which form a folding frame. The individual frame members pivot relative to one another so as to additionally form a wheeled cart with elevated handle, a carrier for elongate objects, or be collapsed into a more compact unit for storage.
In U.S. Pat. No. 4,487,345 issued to Pierce et al. is disclosed a backpack having a wooden frame, a pack, and shoulder straps, wherein the frame unfolds to form a reclining chair which also functions as a stand for holding the pack in an upright position. The chair does not oscillate nor rock and has fixed reclining positions.
In U.S. Pat. No. 3,828,992 issued to Cerchione is disclosed a backpack having a tubular metal folding frame, a pack, and shoulder straps, wherein the frame unfolds to form a sleeping cot with the pack stowed there below. The frame has two elongate sections hingedly connected together by a short section with a flexible sleeping surface stretched therebetween. When used as a backpack one elongate section to which the shoulder straps are connected fits against the back of the user with the other long section to which the pack is attached spaced from and parallel thereto, the two being interconnected by the short section over the top of the pack.
Various types of chaise lounges having a single elongate seat which supports person head to foot are also known but none having the construction and features of the present invention.
SUMMARY OF THE INVENTION
In accordance with the invention, a folding rocking chair and chaise lounge of the type having a pair of oppositely inclined, diagonally disposed frames, one frame being of such width as to nest one within the other with the frames interconnected at the sides thereof by a pair of upper and lower siderails. Each frame has a pair of elongate side members held in a fixed, spaced relationship by one or more cross members. A rectangular, longitudinally flexible seat extends between and is connected at opposite ends thereof to cross members at the upper ends of the respective frames. A folding footrest may also be provided which likewise nests within the frames and which forms a chaise lounge when an extra-long seat is utilized. The nesting of the frames allows the chair to be folded into a compact rectangular unit about two and one half inches thick for storage or transport, with the unit being maintained in the folded position by pins which fit into corresponding apertures in the respective frames.
The first frame, or backrest frame, comprises a pair of elongate side members laterally connected by one or more cross members, typically both upper and lower cross members, the upper portion of the backrest frame being adapted for receiving and supporting a user's back in conjunction with the flexible seat, and a lower portion which functions as the front legs of the chair. The second frame, or seat frame, comprises a pair of elongate side members laterally connected by one or more cross members, typically both upper and lower cross members, the upper portion of the seat frame being adapted for receiving and supporting a user's buttocks and legs in conjunction with the flexible seat, and a lower portion which function as the rear legs of the chair. The backrest frame and the seat frame are typically constructed from naturally finished or unfinished wood, particularly hardwoods such as oak or maple for strength and rigidity. The members of each frame are joined together such as by corrosion resistant stainless steel or zinc plated metal screws and may also be glued together for added strength. The frames may alternatively be made from metal, plastic, composites, or other similarly rigid types of material available in solid or tubular sections. The frames can also each be made from metal tubing or bar stock bent into a U-shape such that the side members and one or more cross members are integral therewith.
The backrest frame and seat frame are maintained in the oppositely inclined, diagonally disposed orientation by means of a pair of upper and a pair of lower siderails. The siderails are typically substantially rigid wooden members constructed from naturally finished or unfinished wood, particularly hardwoods such as oak or maple though metal, plastics, and composite materials may also be used. Each upper siderail is connected such as by using bolts and nuts or sleeved rivets, at one end to a mid-portion of the respective backrest frame side member and at the opposite end to an upper portion of the respective seat frame side member. Each lower siderail is connected such as by using bolts and nuts or sleeved rivets, at one end to a lower portion of the respective backrest frame side member and at the opposite end to a lower portion of the respective seat frame side member. The substantially rigid upper and lower siderails are typically all the same length with their connection points to the respective frame side members in the same longitudinal position on the side members of the respective frames for the pair of upper siderails and for the pair of lower siderails. This configuration allows the chair to fold properly into a compact unit. While substantially rigid siderails are preferable, flexible siderails such as metal chains, nylon rope, and cables may be used, though the chair will not fold as easily and extra retaining pins may be necessary to hold the chair in the folded position. When flexible siderails are used such as chains, the effective length thereof can easily be changed such as by attachment at the desired number of links of the chain between a pair of hook connections attached to the respective frame side members. This allows the various chair positions to be achieved without having the multiple alternate attachment points for the siderails.
Since the backrest frame and the seat frame are not pivotally connected at a fixed point such as where the frames cross, a saddle hinge is formed wherein the effective pivot point can move relative to the frames so as to allow an oscillating or rocking motion to be effected by a user of the chair. As the chair is rocked from a forward position rearward, the angle of the respective backrest frame and the seat frame change from a relatively upright chair with a generally more vertical backrest frame and a generally more horizontal seat frame to a rearward reclining position with the backrest frame in a generally more horizontal position with the seat frame in a generally more vertical position. The chair can be held in one or more predetermined positions so as to not rock by providing apertures in the respective backrest frame and seat frame side members, which apertures are positioned so as to align when the chair is in the desired position such that a pin can be inserted into each pair of apertures. While the chair can be pinned in any functional position thereof including when the seat is horizontal, typically there are provided apertures in the respective side members for the chair to have at least a forward chair position, an intermediate chair position, and a reclining chair position.
The chair can be equipped to be rocking or fixed type chair with foot support by utilizing a fold-out footrest to which the seat is not attached and which nests within the backrest and seat frame and which is pinned in place such that when the chair is in the folded position it forms the same compact unit for storage and transport. The chair can be equipped to be a chaise lounge by using an extra-long seat which attaches to the foot support on the footrest rather than to the seat frame. The reclining chair may be used with the footrest in a deployed position wherein a padded foot support member pivotally adjusts to support a user's feet in the various chair positions or in a pinned and folded or stowed position wherein the foot support member serves as a padded back support for the user. The footrest has two versions primarily for aesthetic appeal, one with a generally rectangular frame and a second having a T-shaped frame both of which essentially function the same as a foot rest. The footrest frames may be made from wood or alternatively from metal, plastic, composites, or other similarly rigid types of material available in solid or tubular sections. The footrest frames can also each be made from metal tubing or bar stock bent into a U-shape such that the side members and one or more cross members or the foot support are integral therewith.
Either footrest may be maintained in an elevated position relative to the floor surface or ground by attaching one of the cross members of the backrest frame in such a position as to contact the footrest frame when the foot support of the footrest is at a comfortable user height for the majority of the chair positions. Multiple vertical positions may be attained by providing removably attached cross members with multiple positions therefor such that the footrest frame contacts the cross members when at different angles, depending on the position of the cross members. The cross members might be in one position when the chair is reclined, and the cross members moved to another position when in the forward chair position. Rubber or plastic pads are typically attached to the footrest frame or the backrest frame so as to act as a cushion between and prevent damage to the frames when the footrest is being lowered.
One or two support legs pivotally connected to the footrest, at a point along the length thereof may likewise be used to maintain the footrest in an elevated position. The support legs contact the floor to help to prevent the chair from tipping over as a person enters or exits the chair. This is a safety feature which works even when the support legs are at a shorter length than required for the particular chair position since as the person enters or exits the chair the legs are still able to touch the ground before an unstable position is reached. On the first version of the footrest, two support legs are used, one on each footrest frame side member, and on the second version one center support leg located between the longitudinal members is used. The support legs may span between the footrest frame completely to the ground to maintain the footrest at a given height above the ground in a particular chair position or may span only partially to act as an anti-tipping device. The support legs can be pivoted to a retracted position substantially parallel to the ground and held there such as by friction at the pivot, a clip, or a pin. The support legs may be of fixed length or of adjustable length with an extendible lower leg with a ground contacting pad such as to be capable of contacting the ground in multiple chair positions.
There are four versions of the rectangular, longitudinally flexible seat on which a user sits, the first three of which are typically made of cloth such as canvas or nylon and the fourth made of substantially rigid slats. Each of the versions of the seat are longitudinally flexible so as to form a comfortable seat which conforms to the back, legs, and buttocks of a user seated therein. The cloth version seats typically have a sheet of resilient foam core sandwiched between one folded-over or a pair of canvas sheets with a sewn seam around the perimeter thereof so as to completely encase the foam core. Alternatively, the seat may be constructed using a thicker open-cell type foam core and made airtight such as by using plastic coated cloth with a glued or heat-sealed perimeter seam and sealing air valve to form an air mattress such as the well known THERMOREST type air mattresses manufactured by several different companies. Air can be admitted or exhausted from the foam in such air mattress seat so as to customize the feel thereof. Also, a separate THERMOREST or other type of air mattress may be laid on top of any of the seat versions for added comfort and may be fixed or removably attached thereto such as by using VELCRO or other type of fastening means.
In the first version of the seat, the ends of the cloth seat are attached to one or more upper cross members of each frame such as by wrapping an end portion of the seat around the respective upper cross member and sewing it back to the seat so as to envelope the respective cross member. The respective cross members may be made to be removably attached such as by bolts and wingnuts to the respective side members so as to allow removal of the seat from the rest of the chair such as for laundering.
The second version of the seat is of substantially the same construction as the first version thereof, but has doubled-over cuff portions at each end thereof of sufficient width as to fit over the upper portion of the backrest and the seat frames including the respective upper cross members and the upper portion of the respective side members. This version of the seat is securely held in place by the cuffs yet may be easily removed by sliding the cuffs off the upper portions of the respective frames without necessitating the removal of any cross members.
The third version of the seat converts the rocking chair with footrest into a chaise lounge. This version of the seat is generally rectangular in shape but of longer length so as to extend from the backrest upper cross members to the footrest. The attachment of the seat to the respective upper cross members and footrest such as by using VELCRO loop pads glued to the upper cross members and to the footrest and VELCRO loop pads sewn or riveted to the footrest, though other methods of attachment to the upper backrest can be utilized such as described above and those same methods adapted to fit on the footrest.
The fourth version of the seat comprises a plurality of substantially rigid, laterally extending bars or slats, typically rectangular in cross-section and made of wood. The slats each have at least a pair of lateral apertures therethrough, one near each end thereof, which extend longitudinally relative to the frames. A flexible member, typically a nylon rope, extends through each aperture at one side of the slats with a pair of knots tied therebetween each, with a second flexible member extending through each aperture at the opposite end thereof with a pair of knots therebetween, the ends of each flexible member tied or otherwise connected to the respective backrest and seat upper cross members. The knots maintain the slats evenly spaced along the flexible member and allow greater flexibility of the seat. Other types of spacers may be used in place of the knots such as tubular spacers made of wood, metal, or plastic.
The chair may be equipped with a pair of wheels pivotally connected to the lower portion of the backrest frame on individual axles and which axles may be reversed so as to not extend from the chair when wheels are not required. The wheels are the rubber pneumatic type or the wooden type for more decorative use such as poolside, though most any type wheel including the plastic and solid rubber types will work.
The wheeled chair has four main uses, the first of which is to allow easier transport of the chair both in the folded position and when in the chair position. In the folded position a user merely grasps the upper portions of the folded backrest and seat frames, tilts the folded chair and pushes or pulls the chair to a new location. The lower portion of the backrest frame, or front legs thereof, may be made of such length as to extend beyond the outer diameter of the wheel when the folded chair is in a vertical position such that in such position the chair will rest on the front legs with the wheels off the ground so as to not inadvertently roll, and will roll only when tipped at a sufficient angle off of vertical for the wheels to touch the ground. When in the chair position, the wheels allow the chair to easily be moved by grasping and lifting the backrest frame such that the lower portion of the seat frame, or the rear legs, lift from the ground such that only the wheels contact the ground. After the chair is moved, the backrest frame is lowered such that the rear legs again contact the ground. If the support legs are deployed they along with a pair of straps connecting the backrest and seat frames help prevent the chair from tipping too far forward to a position wherein the chair might roll backwards on the wheels or tip. Also, the lower ends of the backrest frame side members touch the ground when the chair is tipped forward sufficiently so as to help prevent rolling of the chair on the wheels.
The second main use of the wheels is to allow the chair to be used as a wheeled hauler for carrying equipment and as a wheelchair for moving a person. The chair with wheels can be used to haul equipment placed on the seat or footrest thereof in any position. A wheelchair position is achieved by tilting the backrest frame forward into the upright chair position and locking it there by inserting a pair of locking pins into the apertures in the backrest and seat frame side members. As such, a person can be wheeled around quite easily with little effort.
The third main use of the wheels is to allow the chair, when equipped with the first version of the footrest, to be used as a cart such as to move heavy items. The cart position is achieved by opening or unfolding only the footrest while the backrest frame and the seat frame remain in a closed or folded position. A load is supported on the upper portion of the footrest frame with the aid of one or more removable flexible or rigid bands which may be placed laterally around the footrest frame so as to help support the load in those areas of the footrest frame which lack cross members. Substantially rigid cross members may also be built into the footrest frame if desired. The cart is tilted like a standard hand cart so as to lift the load onto the wheels for transport. If the first version of the adjustable position footrest mechanism is used, either position may be utilized depending on the desired angle between the backrest and seat frames with the footrest frame in the cart position. Optional short folding legs may be used at the ends of each footrest frame longitudinal member to prevent the footrest frame from touching and possibly being abraded by the ground.
The chair can also be equipped for hiking and camping by attaching a removable pack to the rear of the chair with removable shoulder straps which attach to an upper cross member of the seat frame and to a lower cross member of the backrest frame. A removable belt can also be attached to the backrest frame lower cross member to further secure the frames to the user. The pack is typically removably attached to the bottom surface of the seat by means such as VELCRO hook and loop pads to the bottom surface of the seat and the pack. The pack can be attached adjacent the area of the seat behind a person's back and shoulders when used as a chair or a backpack, or below a person's buttocks when used as a chair for easy access such as to beverages or other items held therein. The pack may also be removably attached to the top surface of the seat if desired. The pack may be used to hold such items as an umbrella, a mist bottle, water bottles, etc. An optional configuration especially for camping and hiking allows the frames and the siderails to telescope and collapse such that the overall length of the folded chair shortens and extends by up to about twelve inches or more.
While the chair shown herein accommodates a single user, the respective frames and seat can be made wider and stronger such as to accommodate larger persons as well as two or more persons sitting in the chair at the same time. Likewise, multiple chairs can be linked together side-by-side or otherwise so as to provide seating for multiple persons.

148
is disposed (FIG.
5
). A pair of wheels
150
, typically of the rubber pneumatic type, are disposed on threaded axles
148
with washers
152
and retained thereon by wingnuts
154
. Wheels
150
are used in certain chair configurations and may be removed for storage and threaded axles
148
may be reversed such that they do not protrude from the sides of the chair (FIG.
6
).
When upper and lower siderails
110
and
112
are substantially rigid members, the placement of the connections thereof to the respective side members must be designed such that the chair folds properly and opens to the desired positions. In such case, typically the attachment points of the pair of upper siderails
110
and the pair of lower siderails
112
to the respective backrest frame and seat frames
40
and
42
are substantially the same on each side of the chair such that the respective pairs of siderails are parallel. Likewise, the distance between apertures
114
and
122
of upper siderails
110
and between apertures
132
and
138
of lower siderails
112
will typically be substantially equal, with upper and lower siderails
110
and
112
being generally parallel to the ground in the chair position to allow the chair to fold up properly. Other configurations wherein the backrest frame
40
and seat frame
42
properly fold and nest together with upper and lower siderails
110
and
112
are also possible.
Once the chair is folded, a pair of pins such as ring handled, spring ball bearing pins
156
are inserted through the respective apertures
158
and
160
of seat frame
42
side members
80
and
82
, apertures
162
of lower siderails
112
, apertures
164
and
166
of backrest frame
40
side members
46
and
48
, apertures
168
and
170
of footrest frame
44
, and apertures
172
of footrest legs
103
so as to retain the chair in the closed or stowed position (FIG.
7
). By removing pins
156
the chair can be easily be unfolded, especially when the upper and lower siderails
110
and
112
are substantially rigid. If upper siderails
110
and/or lower siderails
112
are flexible, an additional pin or pair of pins (not shown) inserted into additional coaxial apertures (not shown) through the respective frames
40
,
42
, and
44
and spaced therefrom may be needed to maintain the same in the proper folded position. Each of the various apertures wherein members pivot relative to one another or wherein pins may be inserted may be made larger such that a metal or plastic bushing (not shown) may be pressfit or glued therein so as to provide a more precise fit and eliminate wear to the respective member, particularly when the members are wooden.
Referring to
FIG. 8
, a rectangular, longitudinally flexible seat
174
has a head end
176
, a foot end
178
, and typically has a canvas top layer
180
and a canvas bottom layer
182
which surround a padded core
184
such as sheet foam, which extends for most of the length thereof. Head end
176
is retained in place by a portion thereof
186
which contains no padded core
184
and which is partially wrapped around backrest frame upper cross member
50
, completely wrapped around cross member
52
, and retained such as by a riveted or sewn seam
188
. Foot end
178
is retained in place by a portion thereof
190
, part of which contains padded core
184
, which is partially wrapped around seat frame upper cross member
84
, with padded core
184
acting to cushion a user's legs, completely wrapped around cross member
86
, and retained such as by a riveted or sewn seam
192
. Seat
174
is typically of such a length as to conform to a person's sitting posture in a chair position. Seat
174
is typically of such a width as to span most of the distance between backrest frame side members
46
and
48
so as to provide a comfortable width seat. An airtight version of the seat (not shown) can be made similarly for use with the chair such as by using plastic coated cloth such as canvas with a glued or heat-sealed perimeter seam and sealing air valve to selectively add or exhaust air. A resilient, thicker open-cell foam is preferable for such use since air is admitted through the air valve by the foam core expanding. Likewise, air is exhausted therefrom by compressing the foam core to expel excess air. This allows the user thereof to customize the feel of the seat with less air providing a more flexible seat and with more air providing a stiffer seat.
Referring to
FIG. 9
, there is shown the unfolded chair with footrest frame
44
extended and with the relative motions of backrest frame
40
, seat frame
42
, footrest frame
44
, upper siderails
110
, and lower siderails
112
shown as the chair rocks from a rear position (solid lines) to a forward position (dotted lines). Straps
127
, shown in a relaxed position, limit the forward travel of backrest
40
to help prevent the chair from tipping over in the forward direction. Foot support
94
is shown in a horizontal position with spring-loaded plungers
97
disengaged from detentes
100
where it would normally be stored with pad
95
against seat surface
174
and footrest frame pinned in place so as to provide back support to the user. In the stored position foot support member
94
can also be stored with ball plungers
97
engaging detentes
101
which positions pad
95
away from the seat surface.
Referring to
FIGS. 1 and 11
, each of the side members
80
and
82
have a plurality of lateral apertures therethrough. The apertures closest to the seat frame upper cross members are apertures
116
and
118
to which upper siderails
110
are typically connected. The chair seat frame
42
typically also has three other pairs of coaxial apertures
210
and
212
,
214
and
216
, and
218
and
220
through seat frame side members
80
and
82
, respectively (FIG.
1
). The preferred backrest frame
40
also has two other pairs of coaxial apertures
222
and
224
, and
226
and
228
through backrest frame side members
46
and
48
, respectively, with all of the these apertures which allow positioning of the chair in various operational positions.
The chair is shown in
FIG. 11
in the cot position such as for sleeping, wherein the end of each of upper siderails
110
are moved from apertures
116
and
118
, respectively, to apertures
210
and
212
. In such a position seat
174
is typically substantially taut so as to function as a generally horizontal sleeping surface. The tautness thereof can be adjusted by providing a lengthened or shortened seat
174
. The chair may be pinned in the cot position by providing suitable apertures (not shown) in backrest frame side members
46
and
48
and in seat frame side members
80
and
82
. When the chair is used as a cot, footrest frame
44
may be deployed and tilted appropriately to support the user's legs as shown so as to form a full length cot or it may be stowed within the backrest frame
40
so as to form a three-quarter length cot. In the cot position, footrest frame
44
is typically at the lower of the two elevational heights so as to be at substantially the same vertical height as is seat
174
for comfort reasons. Adjustable legs
236
(
FIG. 13
) or fixed length legs
104
(
FIG. 11
) may be deployed when in the full cot position for added stability though such deployment is not necessary.
Referring to
FIGS. 10 and 12
, therein is shown the means by which footrest frame
44
is angled up or down so as to change the vertical height of footrest frame
44
and foot support
94
. In the raised position of footrest frame
44
, backrest frame lower cross member
54
is secured by bolts
60
in apertures
65
and
66
while backrest lower cross member
56
is secured by bolts
60
in apertures
67
and
69
of backrest side members
46
and
48
, respectively, such that footrest lower cross member
93
contacts backrest frame lower cross member
54
and the lower pair of pads
106
on footrest frame side members
90
and
91
contact backrest cross member
56
to distribute the load therebetween and hold footrest frame
44
in an upper vertical position (FIG.
10
). In the lower position of footrest frame
44
, backrest frame lower cross member
54
is secured by bolts
60
in apertures
63
and
64
while backrest lower cross member
56
is secured by bolts
60
in apertures
69
and
70
such that footrest lower cross member
93
contacts backrest frame lower cross member
54
and the upper pair of pads
106
on footrest frame side members
90
and
91
contact backrest cross member
56
to distribute the load therebetween to hold footrest frame
44
in a lower vertical position (FIG.
12
). Such change in the position of backrest frame cross member
56
is easily made by removing wingnuts
62
, removing bolts
60
, and reattaching cross member
56
. The length of footrest frame
44
may also be changed by moving axles
148
from apertures
144
and
146
of footrest side members
90
and
91
, respectively, to either apertures
229
and
230
or apertures
231
and
232
so as to accommodate shorter people and children.
In all of the positions shown the chair has an oscillating or rocking function. In some instances, it might be desired to restrain the rocking. In such cases spring ball bearing pins
156
(
FIG. 1
) may be inserted into pairs of apertures in backrest frame side members
46
and
48
and seat frame side members
80
and
82
.
FIG. 13
illustrates the chair as restrained in a semi-reclining position wherein pins
156
are disposed in the pair of apertures
214
and
226
, and the pair of apertures
216
and
228
of seat frame
42
and backrest frame
40
, respectively. In
FIG. 14
is illustrated a full reclining position wherein spring ball bearing pins
156
are disposed in the pair of apertures
218
and
222
, and the pair of apertures
220
and
224
of seat frame
42
and backrest frame
40
, respectively. Likewise, the cot position of
FIG. 11
may be restrained from rocking by adding additional apertures (not shown) positioned appropriately in side members
46
,
48
,
80
, and
82
and pinning using spring ball bearing pins
156
. Foot support
94
may be used as a small table to hold a food plate or other articles thereon, particularly useful when the chair is pinned in an upright position such as in FIG.
13
.
Footrest frame
44
is relatively rigid in its unfolded or deployed state as supported on pads
106
by cross member
56
(FIGS.
10
and
12
). There may, however, be cases wherein greater footrest rigidity is desired. In such cases, the use of fixed length legs
104
(
FIGS. 1 and 11
) can be used to add such rigidity. However, such legs
104
only work if they are of such a length that which corresponds with the particular chair position desired. However,
FIGS. 13 and 14
illustrate how the length of legs required can vary drastically between the various chair positions. In such cases, adjustable length legs may be used to remedy the situation.
Referring to
FIG. 15
, an adjustable length leg
236
comprises an outer member
237
with an upper aperture
238
, which outer member
237
is typically pivotally and removably attached to footrest frame outer members
90
and
91
such as by a bolt
106
and wingnut
62
as fixed length legs
104
(FIGS.
1
and
11
). A cylindrical aperture
239
extends for at least a portion of the length of outer member
237
with an internally threaded insert
240
pressfit therein. An inner leg
241
having an externally threaded rod
242
and a ground contacting floor pad
244
, is threaded into insert
240
in outer member
237
. The effective length of leg
236
can be adjusted by threading rod
242
further into or out of outer member
237
.
Alternately, an adjustable length leg
250
as illustrated in
FIG. 16
may be used. Leg
250
has an outer member
252
with an upper aperture
254
, which outer member
252
is typically mounted to footrest frame
44
in the same manner as outer member
232
. An aperture
256
extends for at least a portion of the length of outer member
252
. An inner leg
258
having a rod
260
of such size as to closely pass through aperture
256
and a ground contacting floor pad
262
, is slidably disposed within aperture
256
. A plurality of crosswise apertures
264
extend through rod
260
each of which are selectively positionable in alignment with coaxial apertures
266
and
268
in the lower part of outer member
252
. A pin such as ring handle, spring ball bearing pin
270
is inserted therethrough so as to change the effective length of leg
250
.
When the chair is equipped with wheels (
FIGS. 1 and 2
) there are several special uses for the chair. For example, in
FIG. 17
the chair configured as a wheel chair such as for providing ease of moving the chair. Legs
70
and
72
of backrest frame side members
46
and
48
contact the ground as the chair is tipped forward to help prevent the chair from rolling backwards when the chair is tipped forward such as when entering or exiting the chair. The chair equipped with wheels can be used for moving a person injured such as while backpacking, an elderly person, or overly exhausted person in need of assistance moving about. In this configuration the chair also functions as a wheeled hauler to transport gear placed on seat
174
. This is the same chair position as in
FIG. 13
wherein the chair is restrained by pinning a non-rocking, semi-reclining position except for the stowed footrest and the addition of pneumatic rubber wheels. Typically wide pneumatic rubber tires are used so as to enable easier transport through soft surfaces such as sand without getting bogged-down therein. When backpacking the wheels are typically removed and the axles reversed so as not to protrude from the frame (FIG.
6
). The tires may be tied to a chair frame and the pins
156
packed such that the wheel chair is available should the need arise while backpacking.
The chair with wheels can also function as a hand truck or cart such as for hauling camping equipment from an automobile to the camp site which cart is illustrated in FIG.
18
. In such a position, backrest frame
40
and seat rest frame
42
are in the folded position with footrest frame
44
in the deployed position and legs
104
are in the stowed position. A pair of elongate flexible bands
280
, typically having VELCRO hook and loop pads (not shown) attached to the respective ends thereof, are wrapped around footrest frame
44
. Bands
280
can be positioned where needed on footrest frame
44
to help support the load carried on the footrest frame
44
. A pair of end support legs
282
may be pivotally attached to footrest frame side members
90
and
91
opposite wheels
150
so as to maintain footrest frame
44
off the ground so as to help prevent unsightly scuffing thereof which may be especially visible in other chair positions. Each of end support legs
282
has a center aperture
284
and is pivotally mounted to the respective footrest frame side members
90
and
91
such as by bolts
286
disposed in apertures
288
and
290
of footrest side members
90
and
91
, respectively. Each of end support legs
282
may be placed in a deployed, ground-contacting position (dotted lines) or in a stowed position (solid lines) by means of wingnuts
292
. A pair of safety pins (not shown) such as the type pins
156
(
FIG. 2
) may be inserted one in each of apertures
274
and
276
through footrest frame side members
90
and
91
after footrest
44
is deployed so as to prevent backrest frame
40
and seat frame
42
from falling from the vertical position and injuring someone. The safety pins bear against backrest frame side members
46
and
48
and possibly also against lower siderails
112
to prevent such falling. The cart is used by loosening wingnuts
292
, pivoting end support legs
282
into the vertical operational position, and tightening wingnuts
292
. After adjusting bands
280
to support a load, the load such as camping gear is placed on footrest frame
44
. Soft gear such as blankets and towels or hard gear such as tent posts can be carried within the loop
278
formed by seat
174
while in the cart position or while in any of the non-chair positions including the completely folded position with wheels and in the backpack position without wheels. The cart is then tilted backwards off of legs
70
and
72
of backrest frame side members
46
and
48
by holding the cart with one of the user's feet and pivoted by pulling on backrest frame
40
such that the load is supported on wheels
150
and wheeled to its destination. Once the load has been transported to its destination, the reverse procedure is used to unload the cart. As the cart is tipped forward to unload, legs
70
and
72
again contact the ground and lift the wheels
150
off of the ground so as to stop rolling of the cart. This function serves as a safety feature to prevent unwanted rolling of the cart during loading and unloading of the cart.
The angle between the backrest frame
40
and footrest frame
44
can be set at two positions if such feature is included in the chair function.
FIG. 18
illustrates a first angular position for footrest frame
44
corresponding to FIG.
10
.
FIG. 19
illustrates a second angular position for footrest frame
44
corresponding to
FIG. 12
, showing the angle between backrest frame
40
and footrest frame
44
increased by moving footrest cross member
56
to the lower position. This alternate angular position may be more comfortable for a shorter person to transport a load using the cart.
There are several alternate versions of some chair components from those previously described, the first of which is the seat. The seat as illustrated in
FIGS. 1 and 8
wraps around backrest frame cross members
50
and
52
, and likewise around seat frame cross members
84
and
86
, all of which cross members are attached such as by screws
58
. Thus, if it is desired to remove seat
174
such as for laundering, the aforementioned cross members, or at least cross members
52
and
86
must be unscrewed from their respective backrest and seat frames
40
and
42
to remove them from seat
174
which process is time consuming. Alternatively, those same cross members may be attached by bolts and wingnuts (not shown) which would expedite the process.
As another alternative, a second version seat
310
is illustrated in
FIGS. 20
,
21
, and
22
. Seat
310
is rectangular, longitudinally extending cloth seat similar to seat
174
(FIG.
8
), with a head end
312
, a foot end
314
, and similar canvas top and bottom layers
316
and
318
surrounding an enclosed padded core
320
. Head end
312
is held in place by a folded over, add-on cuffed portion
322
which is wider than the portion of seat
310
between head and foot ends
312
and
314
, and which is riveted or sewn such as at seam
323
. Cuffed portion
322
which does not contain any portion of padded core
320
, has riveted or sewn seams
324
and
326
so as to form a backrest frame receiving pocket
328
into which backrest frame upper cross members
50
and
52
removably fit along with the upper portions of backrest frame side members
46
and
48
each of which protrude through an aperture
330
and
332
, respectively. Foot end
314
has a folded over, add-on cuffed portion
334
which is likewise wider than the portion of seat
310
between head and foot ends
312
and
314
and which is riveted or sewn such as at seam
336
. Cuffed portion
334
, part of which contains a portion of padded core
320
, has riveted or sewn seams
338
and
340
so as to form a seat frame receiving pocket
342
into which seat frame upper cross members
84
and
86
removably fit along with the upper portions of backrest frame side members
80
and
82
. For added user comfort, the cuffed seat (not shown) could be made wherein the a cuffed end of the seat fits over only the upper ends of the seat frame side members
80
and
82
and wherein seat cross members
84
and
86
are moved from the end of seat frame
42
and/or removed therefrom such that the seat conforms to and cradles a user's legs rather than being held substantially flat by cross members
84
and
86
.
A third version extra-long seat
344
is shown in
FIG. 14
which converts the chair to a full-length chaise lounge. Seat
344
extends from backrest upper cross members
50
and
52
to foot support
94
and pad
95
. Seat
344
is a rectangular, longitudinally extending cloth seat similar to seat
174
(FIG.
8
), with a head end
345
, a foot end
346
, and similar canvas top and bottom layers
347
and
348
surrounding an enclosed padded core (not shown). Seat
344
is typically removably attached to the chair such by VELCRO hook pads
349
,
350
, and
351
affixed such as by riveting or sewing to head and foot ends
345
and
346
, respectively, and VELCRO loop pads
352
,
353
, and
354
affixed such as by adhesives to backrest upper cross members
50
and
52
, and to foot support pad
95
, respectively. Alternatively, foot support pad
95
may be omitted and loop pad
354
attached directly to foot support
94
. Seat
344
drapes over but is typically not attached to seat frame upper cross members
84
and
86
. While this particular version of the seat is removable, the other three versions of the seat may be made longer and the foot end adapted to mate with the foot support member so as to form a chaise lounge.
A fourth version seat
360
is shown in
FIGS. 23 and 24
. Seat
360
differs from seats
174
and
310
as it does not comprise canvas or other cloth with a foam core, but rather comprises a plurality of spaced apart, laterally extending substantially rigid slats
362
each typically made of wood with a substantially rectangular cross section. Each of slats
362
typically has a pair of laterally extending apertures
364
and
366
therethrough, one adjacent each respective end thereof, and through each of which extends an elongate flexible member, typically nylon ropes
368
and
370
, respectively, having a plurality of knots
372
and
374
, respectively, which maintain slats
362
in the spaced relationship. First ends
376
and
378
of ropes
368
and
370
, respectively, are attached to one or both of backrest frame upper cross members
50
and
52
such as by tying thereto. Second ends
380
and
382
of ropes
368
and
370
, respectively, are attached to one or both of seat frame upper cross members
84
and
86
such as by tying thereto. Other types of elongate flexible members may also be used such as ropes made from other materials, cables, or even chains with spacing of the slats maintained by a plurality of tubular or other type of spacers (not shown) in place of knots
372
and
374
. Also, a single rope, cable, or chain may be used in place of ropes
368
and
370
, such that the free ends thereof are attached to an upper cross member with a loop thereof attached to the upper cross member at the opposite end of seat
360
.
An alternate version wheel
390
is shown in
FIG. 23
which is primarily used for decorative purposes such as around a pool to match the appearance of slat seat
360
, especially when wooden natural finish or unfinished slats are used. Wheel
390
is capable of the same functions as rubber wheel
150
and is typically made from a plurality of boards
392
and
394
which are naturally finished or unfinished for maximum decorative appeal, though a solid wood or plywood disc could also be used. Wheel
390
has bushings or ball bearings (not shown) in the center thereof and mounts to axle
148
in the same manner as wheel
150
(FIGS.
1
and
5
). An optional rubber tread (not shown) can be secured to the outer periphery of wheel
390
to cushion the ride thereof against the ground.
An alternate version of footrest frame
44
is illustrated in
FIGS. 25
,
26
, and
27
, which typically directly interchanges with footrest frame
44
. Footrest frame
410
comprises a pair of longitudinal members
412
and
413
, a pair of cross members
56
and
414
, and a pair of end members
416
and
417
attached together such as by screws
58
. End members
416
and
417
have axle apertures
418
and
419
, respectively, through which bushing
147
and axle
148
extend so as to attach footrest frame
410
to the chair as is footrest frame
44
. Alternatively, bushings
147
and axles
148
may extend through apertures
420
and
421
or apertures
422
and
423
or apertures
429
and
431
to shorten footrest frame
410
for shorter people and children. The box structure formed by cross members
56
and
414
, and end members
416
and
418
, together with the spaced relationship of longitudinal members
412
forms the reasonably rigid structure of frame
410
.

, respectively, and through an aperture
434
in a block
435
sandwiched between longitudinal members
412
and
413
and secured thereto by means of wingnut
62
. A bolt
436
extends through apertures
438
and
439
in longitudinal members
412
