Title: Chaise Lounge Having A Gas Cylinder

Description:
CLAIM OF PRIORITY 
     This application claims priority to U.S. Ser. No. 61/281,197 filed on Nov. 13, 2009, the contents of which are fully incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The invention relates to power adjustable reclining furniture, in particular to lounge chairs. 
     BACKGROUND OF THE INVENTION 
     The invention relates to a chaise lounge having a power adjustable back rest. As a chaise lounge is a chair for relaxation, a perfect reclining position would be very desirable. A chaise lounge with a reclining backrest has been known in the art for some time. However, the presently known examples in the art typically have adjustment structures that utilize a rack and a locking post. These systems are very simple and cheap to manufacture, but they offer a limited number of adjustments. In addition, prior art adjustable back racks typically require a user to get off the chair in order to make an adjustment, or to remember to adjust the back rest prior to using the chair. These mechanisms, therefore, tend to be burdensome and inconvenient. For example, if someone is relaxing on a chair, and wishes to raise or recline the back rest, having to get off the chair to do so may be highly disruptive to their relaxation. Furthermore, if they are holding food containers, books, bottles or other items, getting off the chair to adjust the locking post may be difficult and may involve the extra burden of finding temporary storage places for these items. 
     The present invention attempts to resolve the problems associated with prior art chaise lounges by having a reclining mechanism that is connected to a cylinder is not limited to a predetermined number of recline settings. Furthermore, the user will be able to adjust the position of the back rest without having to get up off the chair. Also the invention may obviate the need to manipulate the back rest itself, which is highly desirable as the back rest is typically made of metal and may be quite heavy. Instead, a desired reclining pitch of the back rest may be achieved with a touch of a button that sets a gas cylinder in motion, and which then causes the back rest to recline or to rise. Other, similarly effective embodiments of the novel mechanism are further disclosed herein. 
     DESCRIPTION OF THE RELATED ART 
     U.S. Pat. No. 4,264,102 discloses a chaise lounge of lightweight durable construction, consisting of a minimum number of parts of readily available materials, which can be assembled without the aid of tools other than conventional ones. The parts can be packaged in a relatively small space for shipping purposes. The chaise lounge has incorporated therein novel or unique means for adjusting the inclination of the back thereof. 
     U.S. Pat. No. 4,521,054 discloses a chaise lounge that has a supporting unit whose longitudinal members are provided with rollers and are slotted to receive arms of a backrest which have pins selectively engageable in notches along these slots and whose free ends are engageable by abutments on the underside of the supporting unit to cantilever the backrest on the latter. 
     U.S. Pat. No. 7,311,359 discloses a zero gravity chair that generally holds an occupant in a position where the angle between the legs and the torso may be greater than 90 degrees. Typically, the legs may also be elevated such that the legs are even with or above a user&#39;s heart. The disclosed zero gravity chair, in some embodiments, enables the backrest portion to pivot relative to the seat portion allowing the user to adjust an angle between the seat portion and the backrest portion. The disclosed zero gravity chair further enables both the backrest and the seat portions to pivot as a unit independent of the angle adjustment. In certain embodiments, the chair also rotates 360 degrees about a vertical axis. 
     Various implements are known in the art, but fail to address all of the problems solved by the invention described herein. One embodiment of this invention is illustrated in the accompanying drawings and will be described in more detail herein below. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a chaise lounge having a base frame and a back rest movably connected to the base frame. The back rest may be adjustable between an upright position and a reclined position. The chaise lounge also has at least one gas cylinder that has a first end that is connected to the base frame and a second end is connected to the back rest. The distance between the first and second ends of the gas cylinder may be increased or decreased thereby moving the back rest between upright and reclined positions. 
     Therefore, the present invention succeeds in conferring the following, and others not mentioned, desirable and useful benefits and objectives. 
     It is an object of the present invention to provide a chaise lounge with an easily adjustable back rest.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals. 
     Reference will now be made in detail to embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto. 
       FIG. 1  is a perspective view of the present invention with a back rest residing in a substantially upright position. Shown are a chaise lounge  10 , a base frame  20 , a parallel base member  30 , a base cross member  40 , an axle  60 , a wheel  70 , a secondary parallel member  80 , lounge parallel members  90 , a lounge frame  110 , a lounge covering  120 , a back rest  130 , a hinge  140 , a hinge axle  142 , a gap  144 , a top part  150 , a bottom part  155 , a cylinder  160 , a plunger  170 , a jacket  180 , a cylinder bracket  190 , a first end  210 , a second end  220 , a control  240 , an actuator  250 , an actuator case  260 , a forward portion  310 , a rear portion  320 , a mid point of the back rest  330 , a left side  340 , a right side  350 . A chaise lounge  10  is preferably used to support a person in a reclining or a sitting position. The power adjustment mechanism of the present invention may be adapted to any article of furniture having a same or similar purpose, without departing from the spirit of the present invention, which is, to grant a user the ability to flexibly and easily adjust the back rest  130 , or any other part of a support structure, with an aide of a power mechanism or motor. It is preferred that the present invention is made from materials that are partially or completely weather resistant, and that the present invention is assembled in a weather resistant manner. 
     The base frame  20  is shown assembled from at least two parallel base members  30 , which may run parallel to each other, forming an arc beneath a lounge frame  110 . In this embodiment, the terminal front end  32  and the rear end  33  may form the legs of the chaise lounge  10 . The terminal front ends may contain cushioning, frictional or anti-scratch cap elements  34 , which may be made out of a material such as, but not limited to, rubber, resin, a natural or artificial fibrous material, a composite material, or some combination thereof, or any material commonly used in the art for this purpose. The cap elements  34  may be disposed on the rear ends  33  instead of the wheels  70 , or anywhere else as a terminating cap for the frame support components. The rear terminal ends  33  may supported on the floor by the wheels  70 . 
     Alternatively, the base frame  20  may be assembled from two or more parallel base members  30  that are substantially straight, or which curve upwards or sideways, and may additionally contain leg supports (not shown), that would support the overall chaise lounge on the ground or floor. Any other frame composition may be possible. For example, presently the base frame  20  functions as a support frame for the lounge frame  110 , however either the base frame  20  or the lounge frame  110  may serve a dual purpose of being a support frame and lounge frame, with separate or integrated leg supports (not shown). 
     The parallel base members  30  may be joined by at least one base cross member  40 , and minor base cross members  30  (shown in other figures). It is preferable that there be a at least one base cross member  40  toward the forward portion  310 , and at least one other base cross member  40  toward the rear portion  320 . There may be additional cross members  40  or diagonal members (not shown). There are preferably several minor cross members  30 . The chaise lounge  10  may be portable and substantially foldable, which may mean that at least one of the cross members  40  or  30  may need to be foldable, and contain a hinge (not shown) either at the joint with the parallel base member  30  or somewhere along the length of the cross member  40  or  30 . The preferred embodiment contains a secondary parallel member  80  that spans the distance between cross members  40  that are located substantially towards the forward portion  310  and the rear portion  320 . The secondary parallel members  80  may be desirable for additional longitudinal rigidity or strength of the base frame  20 , at least one secondary parallel member  80  may be included or this component may be omitted entirely in an alternative embodiment. 
     Both the base frame  20  and the lounge frame  110  may be made of same or different materials. Either frame component  20  or  110  may be made of a material such as, but not limited to, a metal, a metal alloy, plastics, wood, or composites or some combination thereof. Other useful materials from which to manufacture any of the components of this invention include materials such as, but not limited to, one or more plastics and resins, including but not limited to plastic, particularly reinforced plastic, ABS, Polycarbonate, Noryl™, PVC, ABS/PVC, PVC/Acrylic, Polysulfone, Acrylic, Polyethylene, Kydex™, PETG; including but not limited to fiberglass, in particular reinforced fiberglass, borosilicate, or quartz; wood; metals, including but not limited to stainless steel, iron, tin, aluminum, copper; rubber including but not limited to natural rubber, SBR, Isoprene rubber, Butadiene rubber, and Chloroprene rubber; still other materials may include resin, wicker, rattan, wrought iron, or fabric; or any combinations or composites of these materials. All of the structural components making up the base frame  20  or the lounge frame  110  may be hollow or solid, and assembled from angular or round tubing. 
     The lounge frame  110  is shown assembled from lounge parallel members  90  for the seat  135  and back rest parallel members  92  for the back rest  130 . The fastener locations  42  indicate the mount location of the cross members (not shown) that link the opposite corresponding parallel members  90  and  92 . The seat terminal ends  91  and the back rest terminal ends  93  may be capped off or contain cushioning, or non abrasive ends such as cap elements  34 . The overall surface of the back rest  130  and the seat  135  may contain a covering  120 . The covering  120  is preferably cushioned either with an expandable material that is stretched over the parallel opposite members  90  or  92 . A cover  120  may be a single uniform sheet of material fabric, wood, wrought iron, or any of the other aforementioned materials, or made in form of a partial or complete netting of individual strands, made from plastic or fabric. The material for the cover  120  may be made out of polyester or rayon or a different natural or synthetic material, animal hide or polymer based substitutes and compounds. The cover  120  may be in the form of padded upholstery. 
     The lounge parallel members  90  connect to at least one hinge  140  at the seat hinge end  95 , while the back rest parallel members  92  connect to the back rest hinge ends  94 . The hinge may be a separate component or may be formed from interlocking back rest hinge ends  94  and seat hinge ends  95 , with a rod or axle  144  inserted into the middle to keep the hinge from coming apart. 
     A gap  142  may form at the hinge  140  between the back rest  130  and the seat  135 , especially when the back rest  130  is an elevated position. Alternatively, the gap  142  may be replaced with a fold in the cover  120 , that may appear as a fold or a extra length of the covering material, which may be retracted or folded in an accordion fashion or otherwise, when the back rest  130  is in a reclining or in a substantially plane position with the seat  135 . An additional support member  96  may exist for a more secure connection with the base frame  20 . Alternatively the back rest  130  and the seat  135  may consist of two substantially planar surfaces, having a hinge  140 , and optionally having a cushioned or non-cushioned cover  120 . In another alternative, the chaise lounge  10  may contain other adjustable members, such as, but not limited to leg sections, foot rests, arm rests, hip and/or lower back sections, lumbar support, or any combination of these or displayed sections. 
     Still referring to  FIG. 1 , partially visible is the cylinder  160 . The cylinder  160  is made up of the first end  210  and the second end  230 . The distance  230  between the first end  210  and the second end  230  is what regulates the reclining angle  165  of the back rest  130 . Also preferably included in the cylinder assembly  160 , is the plunger  170  and a jacket  180 . The first and second ends  210  and  230  connect to either the back rest  130  or the base frame  20  or the seat  135  with brackets  190 . The control  240  preferably acts to extend or contract the cylinder  160 . The control  240  may be assisted by the force gravity, such as when a user leans against it, or the cylinder  160  may be operated by a hand or foot lever of an alternative appearance or embodiment than shown. 
     The underside of one embodiment of the chaise lounge  10  of this invention is shown in  FIG. 2 . Shown are two cylinders  160  along with their supporting frame structures. Also shown in  FIG. 2  are a base frame  20 , a parallel base member  30 , a terminal front end  32 , a terminal rear end  33 , cap elements  34 , a base cross member  40 , a minor base cross member  50 , an axle  60 , wheels  70 , secondary parallel members  80 , a lounge covering  120 , a cylinder  160 , a plunger  170 , a jacket  180 , a cylinder bracket  190 , a cylinder cross member  200 , a first end  210 , a second end  220 , a distance between the first and second ends  230 , a control  240 , an actuator  250 , an actuator case  260 , a control cable  270 , O rings  272 , a forward portion  310 , a rear portion  320 , a left side  340 , and a right side  350 . 
     The cylinder  160  preferably contains a jacket  180  around a plunger  170 . The cylinder  160  is preferably a gas cylinder; however hydraulics, oil, or a spring loaded mechanism is also possible. The gas is preferably air that is admitted into an empty cavity of the jacket  180  to decrease the reclining angle  165  and raise the back rest  130 , or expelled from the jacket  180  with a plunger  170 , to increase the reclining angle  165  and lower the back rest  130 . The control  240  operates an air valve either within the actuator case  260 , along the cable  270  or within the cylinder  160 . The control  240  together with the cylinder  160  constitutes the preferred embodiment of the means of increase and decrease of the distance  230 . One skilled in the art will appreciate that most prior art chaise lounges may be modified by adding the cylinder or cylinders  160  and a control  240  that are mounted within the brackets  190 . No further modifications would be necessary. This is superior to prior art devices, where the devices contain extensive structural and design adaptations, intended to accommodate the presence of any included cylinders or other power mechanisms. In contrast, the prior art chaise lounges may be retrofitted with the cylinder mechanism  160  along with the control  240 , without the need for structural modifications. Other embodiments of the control  240  and the cylinders  160  may be desired. 
     The preferred gas cylinder  160  is a Sabilus® Bloc-o-lift model 732168 0300N 257/09 A R. However, any locking cylinder  160 , whether gas filled or not, may be used. The jacket  180 , which is commonly known in the art as the pressure tube may be filled with gas, typically nitrogen. The jacket  180  may alternatively be filled with oil or contain a combination with oil and gas. The plunger  170 , also commonly referred to in the art as a piston rod, may be connected to a spring loaded piston (not visible) that is within the jacket  180 . The plunger  170  may also contain an actuation mechanism that connects to the control cable  270 . The control cable  270 , which may be known in the art as the Bowden cable, pulls or presses on the actuation mechanism. 
     The actuation mechanism is connected to a valve that is separate from or that is incorporated into the aforementioned spring loaded piston. Therefore, a yanking or a thrusting actuation of the control cable  270  opens the valve to allow for a transfer of gas from one side of the piston to the other. The internal configuration of the preferred gas cylinder  160 , or any reasonable alternative, is biased towards extension, meaning, towards the increase of the distance  230 . To decrease the distance  230 , one will need to put a slight pressure on the backrest  130 , while concomitantly activating the cable  270 . 
     The cable  270  is controlled remotely by the control  240 , which contains an actuator  250 , which is commonly a button or a lever that exerts a pull or a thrust on the cable  270  and which is then released to lock the cylinder  160  at a desired distance  230 . In this embodiment, the term remotely means that the control  240  is not connected directly to the piston, but is rather located on the base frame  20  or on the lounge frame  110 . The preferred control  240  is mechanical, but the actuator may be connected to an electric motor that powers a pulley that would operate the cable  270 . As visible in  FIG. 2 , the control contains a twin connection  265  for the cables  270 , since the preferred embodiment contains two gas cylinders  160 . Thus an activation or a release of the control  240 , may have an equal effect on both cylinders  160 . 
     The cylinder  160  mounts to the base frame  20  using a bracket  190 , which may be a combination of a frame mounted bracket and an eyelet, or a bracket with a angle joint or a ball socket joint. As best visible in  FIG. 3 , the first end  210  contains a fitting, which is preferably an eyelet, a joint or a ball socket joint. This fitting may be connected to a hinge portion of the extended arm  192  that is mounted on the backrest  130 . 
     The distance  230  may be increased or decreased manually if a user activates the actuator  250  of the control  240  to open the air valve, and at the same time, pulls on the top part  150  of the back rest  130 . Alternatively, the hinge  140  may be spring loaded and biased towards an upright position. In this embodiment, a user may sit up slightly to relieve the back rest  130  of his or her body weight, thus causing the distance to  230  to increase, creating additional vacuum biased cavity inside the jacket  180 , to be filled with air rushing in through an open valve. In such an embodiment, the cylinder  160  will likely require an inner or an outer spring that will resist the increase of the distance  230 , so that the back rest  130  will not continue to swing upwards even when the actuator  250  is released and the air valve is closed. The air valve is preferably biased to close, so that when the control  240  is disengaged, the valve will close by default. 
     The air that enters into an open valve goes through the cabling  270  and into the cavity of the jacket  180 , thus exerting pressure on the plunger  170  causing it to recede, or in other words, causing the jacket to move in the direction that increases the distance  230 . Incidentally, the distance  230  is also the range of the minimum and the maximum length of the cylinder  60 , which may preferably be between 1 foot when fully contracted and 3 feet when fully extended, however other lengths may be possible, for example, a cylinder that connects toward the forward section  310  may need to be longer that the above stated range. Alternatively the minimum distance  230  may be as small as 3″ while the maximum distance  230  may as long as 60″ (inches). 
     The first end  210  is shown connected to the back rest  130 , while the second end  220  is shown connected to a bracket  190  on along the parallel base member  30 . Alternatively, the mount points of the first and second ends  210  and  220  may be reversed, or placed diagonally, such that the first end  210  may connect to the back rest  210  left side  340 , while the second end  220  will connect to the base frame  20  or the lounge frame  110  on the right side  350 . One skilled in the art will appreciate that pursuant to the discussion herein, the connection of the first and second ends  210  and  220  may be reversed with respect to the base frame  20 , the lounge frame  110 , the back rest  130 , and with respect to right and left sides  350  and  340 . The connection of the first end  210  and the second end  220  to the brackets  190  causes the distance  230  to increase and the back rest  130  to rise into an upright position ( FIG. 1 ) or to sink into a reclining position, with the decrease of the distance  230  ( FIG. 2 ). 
     The distance  230  may be increased or decreased electronically. In one possible embodiment the actuator  250  for the control  240  would be connected to an electrically powered air pump. The air valve may also be electrically opened or may be manually opened to release air. Thus, to decrease the reclining angle  165  by increasing the distance  230 , an actuator  250  may engage an electronic air pump, which will suction air from the surrounding environment, or from an air tank (not shown), and channel it through the cables  270  into the jacket  180 . The air will exert pressure onto the plunger  170 , causing it to recede and concomitantly, also exert an upward pressure on the first end  210 , or alternatively, on the second end  220 , thus increasing the distance  230 , the length of the cylinder  160 , and the upright elevation of the back rest  130 . The advantage of an electronic mechanism is that a user need not shift or otherwise move one&#39;s body to raise or lower the back rest  130 . However, in a manual mechanical embodiment, the chaise lounge  10  is more autonomous, benefiting from lower maintenance in not having to change batteries or to locate an electrical outlet to power the electric mechanism. 
     Other alternatives may be possible. For example the cylinder  160  may contain compressed air in a separate tank, which is pumped from such tank into the jacket  180  increase the distance  230  and then pumped back into the tank from the jacket  180  to decrease the distance  230 . The control  240  may be in a form of a manual lever or a pedal (not shown), that when depressed, causes air to enter the jacket  180 . Thus, successive depressions result in pumping of air into the jacket  180  and the raising of the back rest  130 . A separate actuator  250  may still be included to expel the air and lower the back rest  130  into a more recline position. 
     In yet another alternative embodiment, a jacket  170  and a plunger  180  telescope with respect to each other while traveling along a thread. Meaning, the plunger  170  would have one side of the thread, while the jacket  180  would have a cooperating side of that thread. The distance  230  would increase or decrease as the jacket  180  turns around the plunder  170 , or visa versa, either clockwise or counterclockwise. The turning motion may be manually driven by a handle or a crank, or may be electronically driven by battery power or alternative current from a wall outlet. An electronic motor or a mechanical crank or lever may also utilize a threaded spring or a spring that is expanded or contracted with a help of a cylinder, for example if a threaded member twists to expand a spring, like a car jack, or a cylinder pulls or pushes on a spring to expand or contract it. A battery power or an alternative current may also drive the preferred embodiment of the cylinder  160  and/or supply power to the control  240 . 
     The jacket  180  and the plunger  170  may be preferably made out of corrosion resistant stainless steel, aluminum or a metal alloy, or a combination thereof. Other possible materials may include, but are not limited to, metal, a metal alloy, plastics, wood, or composites. Other useful materials from which to manufacture any of the components of this invention include one or more plastics and resins, including but not limited to plastic, particularly reinforced plastic, ABS, Polycarbonate, Noryl™, PVC, ABS/PVC, PVC/Acrylic, Polysulfone, Acrylic, Polyethylene, Kydex™, PETG; including but not limited to fiberglass, in particular reinforced fiberglass, borosilicate, or quartz; wood; metals, including but not limited to iron, tin, copper; rubber including but not limited to natural rubber, SBR, Isoprene rubber, Butadiene rubber, and Chloroprene rubber; still other materials may include resin, wicker, rattan, and wrought iron; or any combinations or composites of these materials. The jacket  180  and the plunger  170  may be made of the same or different materials. The first end  210  and the second end  220  may contain lubricated gaskets or ball bearings, so as to rotate within the brackets  190 . Additionally, there may be rubber gaskets at the traveling end of the jacket  181 , so as to prevent any escape or leakage of the air, or gas out of the cylinder  160 , which may lead to a sudden and jarring drop in the upright relining pitch of the back rest  130 . 
       FIG. 3  is a detailed perspective view of the present invention shown in perspective, with a focus on the underside of the overall frame support  20  and  110 . Visible in  FIG. 3  are a chaise lounge  10 , a base frame and  20 , a parallel base member  30 , a terminal front end  32 , a terminal rear end  33 , cap elements  34 , a base cross member  40 , fasteners  42 , a minor base cross member  50 , an axle  60 , wheels  70 , lounge parallel members  90 , seat terminal ends  91 , back rest parallel members  92 , back rest terminal ends  93 , back rest hinge end  94 , seat hinge end  95 , lounge cross members  100 , a lounge frame  110 , a back rest  130 , a seat  135 , a hinge  140 , a hinge axle  142 , a cylinder  160 , a reclining angle  165 , a plunger  170 , a jacket  180 , a cylinder bracket  190 , a bracket arm  192 , a cylinder cross member  200 , a cross member hinge  205 , a first end  210 , a second end  220 , a mid point of the back rest  330 , a left side  340 , and a right side  350 . 
     It is preferable to have at least two gas cylinders  160  disposed the left and right sides  340  and  350  of the chaise lounge  10 , since this would increase the stability and sturdiness of the back rest  130 . It would also decrease the effort and time expanded on raising the back rest  130 , especially in manually enabled mechanisms. Alternatively, one or more cylinders  160  may be provided in a central or side location, and either parallel to or diagonal to the parallel members of the frame  30 ,  90  and  92 . A different number or type of cylinders is also conceivable and will not depart from the spirit of the present invention. 
     The bracket  190  attached to the back rest  130  is preferably located at, or exerts pressure onto the midpoint section  330  of the back rest  130 , so as to minimize the lever affect of the top end  150 . To minimize the required extension distance  230  or the length of the cylinder  160 , the bracket  190  that attaches to the back rest  130  contains an extended arm  192 . When the back rest  130  is fully reclined, the extended arm  192  is preferably at a lower plane than the bracket  190  that is attached to the parallel base member  30 . It follows, that when the lounge frame  110  is fully reclined, the cylinder is in a diagonal position, with first end  210  pointing downward, or in a second end  220  pointing downward if the order of the plunger  170  and jacket  180  is reversed ( FIG. 5 ). Therefore, such disposition of the extended arm  192  causes a big variation of upward elevation or downward reclining of the back rest  130 , despite a comparatively small adjustment of the distance  230 . It should be mentioned that the adjustment setting is only limited by the minimum and maximum extension lengths of the cylinder  160 . Within this range however, the number of adjustment settings is unlimited. 
     It is preferable that the first end  210  attaches to the back rest  130  at the cross member hinge  205 . The cross member hinge  205  may be lubricated or contain ball bearings to more easily rotate the first end  210  within the bracket  192  or around the cylinder cross member  200 . The cylinder cross member  200  is provided to ensure that both cylinders are extending or contracting to the same degree so that the back rest  130  remains substantially level, however it&#39;s presence is not strictly necessary. Alternatively, the brackets  190  either on the back rest  130  or the parallel base member  30 , or the seat  135  may be omitted with the cylinder attaching to a minor base cross members  50 , to a base cross member  42  and to a lounge cross member  100  or a minor lounge cross member  105 . Furthermore the axle  60  may be eliminated and replaced with minor base cross member  50  extending outwardly on either right and left sides  350  and  340 , beyond the parallel base members  30 , thus providing mount points for the wheels  70 , which may be removable. 
       FIG. 4  is another view of the preferred embodiment of the present invention, displaying the rear portion  320  of the chaise lounge  10 . Also shown in this  FIG. 4  a parallel base member  30 , a terminal rear end  33 , an axle  60 , wheels  70 , a lounge parallel members  90 , a back rest parallel members  92 , a back rest terminal ends  93 , back rest hinge end  94 , seat hinge end  95 , minor lounge cross member  105 , a lounge covering  120 , a back rest  130 , a seat  135 , a hinge  140 , a hinge axle  142 , a top part  150 , a bottom part  155 , a cylinder  160 , a cylinder bracket  190 , a bracket arm  192 , a cylinder cross member  200 , a first end  210 , a rear portion  320 , a left side  340 , and a right side  350 . This figure demonstrates that that the gap  144  ( FIG. 1 ) may be replaced by an extended hinge  140  or a hinge axle  142 , or a fold in the lounge covering  120 . Pursuant to the discussion herein, one skilled in the art will appreciate that the first end  210  may also be represented as the second end  220 . 
       FIG. 5  is another perspective view of the present invention, shown with several alternative embodiments. Shown in  FIG. 5  are a chaise lounge  10 , a base frame and  20 , a parallel base member  30 , terminal front end  32 , a terminal rear end  33 , cap elements  34 , a base cross member  40 , fasteners  42 , an axle  60 , wheels  70 , a secondary parallel member  80 , seat terminal ends  91 , back rest parallel members  92 , back rest terminal ends  93 , a lounge frame  110 , a lounge covering  120 , a back rest  130 , a seat  135 , a hinge  140 , a hinge axle  142 , a gap  144 , a top part  150 , a bottom part  155 , a cylinder  160 , a reclining angle  165 , a plunger  170 , a jacket  180 , a cylinder bracket  190 , a bracket arm  192 , a cylinder cross member  200 , a cross member hinge  205 , a first end  210 , a second end  220 , a distance between the first and second ends  230 , a control  240 , an actuator  250 , an actuator case  260 , a control cable  270 , an armrest  280 , a parallel armrest member  290 , an armrest support  300 , a forward portion  310 , a rear portion  320 , a mid point of the back rest  330 , a left side  340 , a right side  350 . 
       FIG. 5  demonstrates that the control  240  may be placed on an armrest  280 . The control  240  should preferably be located in a place were it can be easily found by groping fingers of a user, or were it can be easily engaged, the lever may also be located on the inner side  295  or on the outer side  296  of the armrest  280  of the chair  10 , and at the same time were accidental engagement is minimized. Some of the locations may be along the top  293  of the armrest  280 , along the bottom  292  of the armrest  280 , or at the terminal ends  294 , whether at the top or bottom  293  or  292  of the armrest  280 . The armrest  280  is shown assembled from a parallel armrest member  290 , which is substantially parallel to the plane of the seat  135  and above it. The arm rest  280  may be located toward the rear portion  320  or more towards the front portion  310 , or all along the length of the seat  135 . The arm rest  280  is shown having a parallel member  290  and two armrest supports  300 . Any number of armrest supports  300  may be used, and the parallel member  290  may instead be a continuous angular or elliptical arch, or may mount to the seat  135  or to the back rest  130 , or to both  130  and  135 . However, in an embodiment where the armrest  280  mounts onto both the back rest  130  and the seat  135 , since the back rest  130  is capable of rising or reclining the armrests  280  will also need to be able to fold or unfold. Therefore, the points of attachment  136  on the back rest  130  or on the seat  135  will require a hinge, with another hinge being disposed somewhere along the length of the armrest  280 . 
     The cylinder  160  is shown with the first point  210  connecting to the base frame  20  and the second point  220  connecting at the bottom of the back rest  130 , engaging the bracket arm  192 . The plunger  170  is connected to the back rest  130 , while the jacket connects to the base frame  20 . The first point  210  or the second point  220  may connect along the base frame  20  toward the rear portion  320  or toward the forward portion  310 . The first point  210  or the second point  220  may connect at the bottom end  155  or anywhere along the length of the back rest  130  between the top and bottom parts  150  and  155 . In two or more cylinder embodiments, one cylinder  160  may have a first point  210  connecting to the back rest  130  with the second point  220  attaching somewhere along the base frame  20 , with the other cylinder or cylinders having the first point  210  connecting to the base frame  20  with the second point  220  connecting to the back rest  130 . The cylinders may be stacked vertically or horizontally with respect to each other or connecting diagonally or crisscrossed to the opposite frame support members. The cylinders  160  may be multi-sectional with multiple telescoping plungers  170  and jackets  180 . 
     In another alternative, the chaise lounge  10  may have several moving or adjustable members in addition to or along with the back rest  130 . In that instance multiple cylinder arrangements, control arrangements and attachment brackets will be required, with all or some of the increasing or decreasing mechanisms being electronic or manual. 
     The cover  120 , which may also be referred to as a lounge cover, may contain a design or a logo that is spread along the back rest  130  and the seat  135 . Alternatively, the seat  135  may have a different design from the back rest  130 . The cover  120  for the back rest may be made from a different material than the seat  135 . The cover  120  for back rest  130  and the seat  135  may be made from padded upholstery or any material commonly used for this purpose, or one of the components  130  or  135  may be made from padded upholstery, with the other made from a stretched sheet of material and additionally secured in place with stitching  153 . The fabric, or material used, should preferably be reasonably frictional, so that a user will not slide toward the forward portion  310 , when the back rest  130  is in an elevated position. The frame supports of the present invention should preferably be fastened, welded crimped, screwed or glued together, or use different or same means of binding different, but adjacent members together. 
     Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
