Description:
This invention relates to a swinging chair; and more particularly to an ergonomically correct swinging chair assembly having ergonomically correct body support cooperating with a movable foot rest to facilitate use thereof. 
     BACKGROUND OF THE INVENTION 
     Many types of chairs, especially chairs for use outdoors, are known. However, it is very desirable to provide an ergonomically correct swinging chair, which provides both ergonomically correct seating and a suitable foot or leg support. No such chair is known in the art. 
     Typically, an ergonomically correct chair provides support to a person sitting thereon, without undue pressure on blood vessels or limbs. Thus, the person can be the comfortable and avoid problems of standard chairs. 
     Using a foot rest with an ergonomically correct chair causes even more problems. If the foot rest is convenient to use, it hinders sitting on or getting out of the chair. Simplification of getting into or out of the chair renders such a foot rest inconvenient to use. If the foot rest is properly positioned to cooperate with the ergonomically correct chair, great advantages are obtained. However, no such foot rest exists. 
     Such requirements become even more complicated when it becomes desirable to have the chair outside or durable enough to survive a lack of shelter. Not only must the chair and is actually, durability must be included therein so that the chair can effectively function. 
     Even more typically, such a chair is not shaped to provide a reasonable amount of comfort for the user of the chair. Even with the ergonomic studies and applications of today, an appropriate chair for this purpose is not available. It is very desirable for the chair to support the body and a fashion. 
     SUMMARY OF THE INVENTION 
     Among the many objectives of this invention is the provision of an ergonomically correct swinging chair assembly with a movable foot rest to facilitate a use of the ergonomically correct swinging chair assembly. 
     A further objective of this invention is the provision of an ergonomically correct swinging chair assembly with a proper foot support. 
     A still further objective of this invention is the provision of an ergonomically correct swinging chair assembly with minimal exterior pressure on blood vessels. 
     Yet a further objective of this invention is the provision of an ergonomically correct swinging chair assembly capable of properly supporting a person therein. 
     Also, an objective of this invention is the provision of an ergonomically correct swinging chair assembly with a foot rest. 
     Another objective of this invention is the provision of an ergonomically correct swinging chair assembly with a movable foot rest. 
     Yet, another objective is the provision of an ergonomically correct swinging chair assembly with a foot rest, which simplifies getting into the chair assembly. 
     Still, another objective is the provision of an ergonomically correct swinging chair assembly with a foot rest, which simplifies getting out of the chair assembly. 
     A further objective of this invention is the provision of an ergonomically correct swinging chair assembly with a proper foot support adaptable for use out of doors. 
     These and other objectives of the invention (which other objectives become clear by consideration of the specification, claims and drawings as a whole) are met by providing an ergonomically correct swinging chair assembly, having a body support cooperating with a foot rest; which footrest may be moved in order to simplify a seating process while a person is being seated, and then returned to a proper position when desired or after the person is seated.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With an ergonomically correct swinging chair assembly and an appropriate foot rest, comfort for a person with proper body support may be obtained. More particularly, the chair assembly has an appropriate arc to its support frame, so that pressure on any particular body point is minimized and all parts of the body have reasonable support from the ergonomically correct swinging chair, especially the entire back side of a person. The side view of such a chair assembly provides a view of the arc for the support surface adapted to support the back side of a seated person. The required arc for a particular person or wide range of people is determined empirically. 
     As an extension of the support surface, a foot rest may provide support for the legs. In a preferred form, the ergonomically correct swinging chair assembly includes a foot rest, which may swing on hinges upwardly from one side of the frame and provide a proper entrance to the body support or seating portion of the chair assembly. After a person is seated, the foot rest may be repositioned for use by the seated person. 
     The frame for the body support of the chair assembly includes a shaped chair truss, which supports the other features of the chair assembly. The shaped chair truss has two arcuate, congruent, or substantially congruent, side members, which joined at a top portion thereof by a top frame bar, which provide for the frame of the chair assembly to provide desired support for a person sitting therein. This suitable shape is provided by the congruent, or substantially congruent, side members. 
     The top frame bar is substantially parallel to the ground when the chair is in use. If desired, the top frame bar may be shorter than the greater width point of the shaped chair truss. With the two congruent side members being at least partially arced adjacent to and extending from the top frame bar, the ergonomic features of the chair may be maintained. 
     A primary support bar connects the two congruent side members and extends there beyond, if desired. Between the primary support bar and top frame bar, a plurality of secondary support bars connect the two congruent side members. The secondary support bars combine with the top frame bar and the two congruent side members to form body support. 
     Also between the support bar and top frame bar is a mounting bar. The mounting bar and the primary support bar combine to provide positioning for the body support so that the person may use the chair. On the secondary support bars, any suitable pad for the frame may be used. 
     In a preferred form, the mounting bar and the support bar can provide any suitable positioning for the body support. It is desired for the body support to having a swinging function, a swinging frame can be provided. If it is desired for the body support to be stationary, an appropriate leg support for the body support can be provided. Whatever support is desired, the mounting bar and the support bar provide attachment points for the support. 
     Also secured to each congruent, or substantially congruent, side member may be a desired arm rest. Each arm rest may also be padded, if desired. The shaped of each arm rest in any shape adaptable for the desired purpose. 
     In a preferred form, it is preferred that the chair support a swinging function, when mounted from a frame assembly. To that end, in order to form the frame assembly, two a-shaped frame sides are connected by a top frame member. The top frame member has a general shape of an upside down or inverted, squared U-shape with a straight base. Each a-shaped frame side has a top post designed to receive the frame joining member. Each a-shaped frame side has, as the straight base, a middle support member designed to complete the desired shape. The parts of the frame assembly are preferably tubular in nature. 
     Two swing bars are movably connected to the top frame member, in order to provide the desired swinging function for the ergonomically correct swinging chair assembly. A pair of mounting bars are spaced apart and secured as support members on each side of the body support. At each opposing end of each swing bar, is a hitch aperture designed to receive the mounting bar attachment an end of the mounting bar and an end of the support bar respectively. 
     Referring now to FIG.  1  and FIG. 2, the ergonomically correct swinging chair assembly  100  of this invention has an ergonomically correct body support  120  mounted on a support frame  250 . The ergonomically correct body support  120  is capable of moving back and forth in a swinging motion. 
     The body support  120  (FIG. 4) of the ergonomically correct swinging chair assembly  100  includes a shaped chair truss  122 , which supports the other features of the chair assembly  100 . The shaped chair truss  122  has a first arcuate side member  126  oppositely disposed from a second arcuate side member  128 . First arcuate side member  126  and second arcuate side member  128  are substantially congruent. With the arcuate members  126  and  128  in proper position, they are joined by a top frame member in the form of top chair bar  130 . First arcuate side member  126 , second arcuate side member  128  and top chair bar  130  may be formed as one unit or as separate pieces. 
     Spaced apart from top chair bar  130  and connected between the arcuate members  126  and  128  is a main support bar  134 . support bar  134  connects the two congruent side members  126  and  128  and extends there beyond. Between the main support bar  134  and top chair bar  130  are a plurality of secondary support bars  136  connecting the two congruent side members  126  and  128 . The secondary support bars  136  combine with the top chair bar  130  and the two congruent side members  126  and  128  to form shaped chair frame truss  122  of body support  120 . 
     To each of first arcuate side member  126  and second arcuate side member  128  are connected chair arms, in order to support the arms of a person sitting in the chair. More particularly, first chair arm  138  is connected to first arcuate side member  126 , while second chair arm  140  is connected to second arcuate side member  128  in a standard fashion. The arms  138  and  140  may be welded, bolted, or otherwise secured as desired to shaped chair truss  122  in general, and to both of first arcuate side member  126  and second arcuate side member  128  in particular. 
     In a preferred form, both first arcuate side member  126  and second arcuate side member  128  have a pair of arm braces  142  (FIG. 6) thereon. Each pair of arm braces  142  extends outwardly from shaped chair truss  122 . 
     Each member of pair of arm braces  142  receives an opposing arm end  144  of first chair arm  138  and second chair arm  140  respectively. As each opposing arm end  144  is secured in its respective arm brace  142 , first chair arm  138  and second chair arm  140  are appropriately secured to their respective first arcuate side member  126  and second arcuate side member  128 , by a nut and bolt assembly, a glue assembly, a welding assembly, or the like. 
     Adding FIG. 3 to the consideration, the structure of the support frame  250  becomes clear. Four congruent, or substantially congruent, frame legs  252  are secured in pairs to the support frame truss  254  as a top member of the support frame  250 . Each frame leg  252  has a truss end  256  to be fastened to the support frame truss  254 . Extending at an angle from truss end  256 , is the leg support member  258  to complete frame leg  252 . 
     Support frame truss  254  has a central chair support  260  with leg supports  262  at each end thereof. Within each leg support  262  are truss apertures  264  adapted to receive a nut and bolt assembly  266 , as truss apertures  264  align with appropriate frame apertures  270 . In this fashion, frame leg  252  is fastened to leg support  262  in order to form the basic structure of frame  250 . 
     Connecting each pair of the leg support members  258  is a strut  272 . Triangulating with central chair support  260  and each leg support  262  is an elbow bracket  274 . A bracket aperture  276  in each end of elbow bracket  274  is alignable with its own frame aperture  270 . Likewise, a strut aperture  278  is alignable with its own frame aperture  270 . Each end of frame leg  252  and frame truss  254  may be sealed with a pipe cap  290 , in order to prevent the entry of water or other undesirable material therein. 
     With the further consideration of FIG. 4, the structure of mounting assembly  300  becomes clear. A back chair mounting rod  302  is secured to shaped chair truss  122  between first arcuate side member  126  and second arcuate side member  128  and close to top chair bar  130 . A front chair mounting rod  310  is secured in a similar fashion, but closer to swinging foot rest  220 . Both front chair mounting rod  310  and back chair mounting rod  302  have U-shaped hooks  314  at each end thereof. Each U-shaped hook  314  is generally inverted. The U-shaped hook  314  may be replaced by a circular aperture. 
     Each of U-shaped hook  314  receives a chair hitch  316  therein. More particular, chair hitch  316  includes a swing bar in the form of an angled rod  318  with a centrally located angle  320 , therein. Chair hitch  316  is completed by closed end loop  322 . Each closed end loop  322  receives therein its own U-shaped hook  314 . Thus, there are two of chaff hitch  316 , and one closed end loop  322  for each of inverted U-shaped hook  314 , for a total of four end loops  322 . 
     In order to provide movement capability for the ergonomically correct swinging chair assembly  100 , a swing eyelet  324  a top angle  320  of chair hitch  316 , eyelet  324  has an eyelet aperture  326  to receive shook  328  of chair hitch  316 . Also swing eyelet  324  has an eyelet bolt  326  passing through frame apertures  270  in support frame truss  254  or in part of nut and bolt assembly  266 , in order to provide a swinging motion. 
     With FIG. 5 joining the consideration, the pad assembly  180  becomes more clear in structure. Back pad  182  fits over top bar  130  and extends down main support bar  134  and adjacent bars. Seat pad  184  fits on secondary support bars  136  and is below the arms  138  and  140 . Pad assembly  180  rests on the secondary support bars  136 . Arm pads  186  may be on each of first chair arm  138  and second chair arm  140 . Similarly, foot pad.  188  may be on a foot rest, such as swinging foot rest  220  or ratchet foot rest  240 . Pad assembly  180  is preferably one piece, but back pad  182  and seat pad  184  may be separate pieces. 
     In FIG. 6, swinging foot rest  220  is added to the consideration. Swinging foot rest  220  is mounted on rod extensions  222  which extends from each of first arcuate side member  126  and second arcuate side member  128 . More particularly, rod extensions  222  included a first rod extension  224  extending from first arcuate side member  126  and second rod extension  226  extending from second arcuate side member  128 . 
     On second rod extension  226  is hinge assembly  230 . Hinge assembly  230  connects swinging foot rest  220  to ergonomically correct swinging chair assembly  100 . Clips  232  secure swinging foot rest  220  to first rod extension  224 . Swinging foot rest  220  is raised when either entering or leaving ergonomically correct swinging chair assembly  100 , and lowered when proper. If desired, rubber tips  234  may be applied to first rod extension  224  and second rod extension  226 . 
     In FIG. 7, hinge assembly  230  is replaced by ratchet foot rest  240  in that ratchet mechanism  242  connects ratchet foot rest  240  to ergonomically correct swinging chair assembly  100 . This ratchet foot rest  240  replaces the swinging foot rest  220 . In this manner, ratchet foot rest  240  moves up and down on the longitudinal axis of ergonomically correct swinging chair assembly  100 , while between swinging foot rest  220  on the vertical axis of ergonomically correct swinging chair assembly  100 . 
     Ratchet foot rest  240  is operated by ratchet cable and reel  244 , which is connected to pulley shaft  246 . Cable  248  may be connected to first chair arm  138 . As first chair warm  138  is raised or lowered, ratchet foot rest  240  responds appropriately, due to the standard connection. Clearly such movement of the ratchet foot rest  240  facilitates either entering or leaving ergonomically correct swinging chair assembly  100 , when desired as does swinging foot rest  220 , as above described. 
     In FIG. 8, a two-person ergonomically correct swinging chair assembly  400  is depicted. More particularly, top chair bar  130  is replaced with elongated bar  402 , with appropriate adjustment in other measurements. Elongated bar  402  requires an adjustment in other members to compensate for two people being able to fit side by side in this version, that is two-person ergonomically correct swinging chair assembly  400 .
