Description

    FIELD OF INVENTION
  • The present invention relates to a recliner.
    • BACKGROUND OF INVENTION
  • U.S. Pat. No. 5,186,518 discloses a conventional recliner. This conventional recliner is however very complicated in structure. This complicated structure includes many parts and eventually entails a very high cost. Moreover, this complicated structure is bulky and heavy. The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
    • SUMMARY OF INVENTION
  • It is an objective of the present invention to provide a recliner with a backrest that can be moved to any desired position within a range.
  • It is an objective of the present invention to provide a recliner with a stool that can be moved to any desired position within a range.
  • It is another objective of the present invention to provide a recliner that is simple in structure.
  • According to the present invention, a recliner includes two frames, a backrest frame pivotally attached to the frames, a stool frame pivotally attached to the frames, a link connected between the backrest frame and the stool frame and a hydraulic cylinder connected between one of the frames and the backrest frame.
  • Other objects, advantages and novel features of the invention will become more apparent from the following detailed description in conjunction with the attached drawings.
    • BRIEF DESCRIPTION OF DRAWINGS
  • The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings.
  • FIG. 1 is a perspective view of a recliner according to the preferred embodiment of the present invention.
  • FIG. 2 is a perspective view of a structure of the recliner of FIG. 1.
  • FIG. 3 is a top view of the structure of the recliner of FIG. 2.
  • FIG. 4 is a cross-sectional view taken along a line 4-4 in FIG. 3.
  • FIG. 5 is a similar to FIG. 3 but shows the structure of the recliner in a different position.
  • FIG. 6 is a cross-sectional view taken along a line 6-6 in FIG. 5.
  • FIG. 7 is a similar to FIG. 5 but shows the structure of the recliner in a different position.
  • FIG. 8 is a perspective view of a structure of the recliner of FIG. 7.
    • DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
  • FIG. 1 shows the profile of a recliner 10 according to the preferred embodiment of the present invention.
  • Referring to FIG. 2, a structure of the recliner 10 is shown. The recliner 10 includes two frames 20, a backrest frame 30, a stool frame 40, two links 50 and a hydraulic cylinder 60.
  • Each frame 20 includes an upper member used as an armrest and a lower member used as a foot. The frames 20 are preferably made of wood in consideration of weight. A beam 21 is attached to each frame 20. The beams 21 are preferably made of metal in consideration of strength. A plurality of springs 22 is connected between the frames 20 in order to support a seat (not shown). A crossbar 23 is connected between the frames 20.
  • The backrest frame 30 includes two links 31 and two crossbars 32 connected between the links 31. Each link 31 is pivotally attached to corresponding one of the beams 21. The pivotal of the links 31 are limited by means of the crossbar 23. Each link 31 includes an upper section and a lower section. Although not shown, a backrest plate is attached to the upper sections of the links 31, and sponge is attached to the backrest plate.
  • The stool frame 40 includes two links 41. Each link 41 includes an upper section and a lower section. The lower section of each link 41 is pivotally attached to corresponding one of the frames 20.
  • Each link 50 is connected between the lower section of one of the links 31 and the lower section of corresponding one of the links 41. Although not shown, a stool plate is attached to the links 41, and sponge is attached to the stool plate.
  • The hydraulic cylinder 60 includes an end attached to one of the frames 20 and an opposite end attached to the lower section of one of the links 31. The hydraulic cylinder 60 includes a lever 61 for the control thereof. The lever 61 can be pivoted between a first position as shown in FIG. 3 and a second position as shown in FIG. 5. When the lever 61 is in the first position, the hydraulic cylinder 60 cannot be extended and shrunk. When the lever 61 is in the second-position, the hydraulic cylinder 60 can be extended and shrunk.
  • Referring to FIG. 3, the lever 61 is in the first position. The hydraulic cylinder 60 cannot be extended and shrunk. Referring to FIG. 4, the backrest frame 30 is in a high position. The backrest frame 30 is retained in the high position by means of the hydraulic cylinder 60 as the lever 61 is in the first position.
  • Referring to FIG. 5, the lever 61 is in the second position. The hydraulic cylinder 60 can be extended and shrunk. Thus, the backrest frame 30 can be pivoted down to a position as shown in FIG. 6. The backrest frame 30 can further be pivoted down to a position as shown in FIG. 7. The backrest frame 30 can be pivoted to any desired position within a range. The backrest frame 30 can be retained in position by means of the hydraulic cylinder 60 when the lever 61 is released and turned back to the first position.
  • The present invention has been described via detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
