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.

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


.




A pivotable foot support


424


having pad
