Abstract

A chair capable of a reduced transportation volume and rapid assembly includes a seat cushion fixing frame and a backrest supporting frame as separate components. The seat cushion fixing frame has an end coupled with an upside-down square U-shaped element bilaterally provided with downwardly extending sections, each section concavely provided with an oblique notch. The backrest supporting frame has an end corresponding in position to the seat cushion fixing frame and penetrated by a fixedly provided bar for being received in the oblique notches of the upside-down square U-shaped element during assembly. A resilient assembly is assembled to a bottom portion of a slot formed in a horizontal section of the backrest supporting frame. The two frames and the resilient assembly can be assembled rapidly without using tools. The seat cushion fixing frame and the backrest supporting frame are detachable from each other for compact packaging, thus effectively reducing transportation and production costs thereof.

Description

    BACKGROUND OF THE INVENTION
  • 1. Technical Field
  • The present invention relates to a chair capable of a reduced transportation volume and rapid assembly, wherein a seat cushion fixing frame and a backrest supporting frame of the chair can be assembled together and securely positioned relative to each other by a simple fastening operation without using tools, and wherein a resilient assembly corresponding in position to an end of the backrest supporting frame is coupled threadingly with the seat cushion fixing frame. The seat cushion fixing frame and the backrest supporting frame are fabricated as separate elements and are detachable from each other for packaging so as to reduce the overall package volume, to facilitate stacking during transportation, and to effectively lower transportation and production costs.
  • 2. Description of Related Art
  • Referring to FIG. 1 and FIG. 2, a commercially available chair assembly typically includes a seat cushion 10, a chair leg unit (not shown), a backrest 30, and left and right armrests (not shown). As shown in FIG. 1, the seat cushion 10 is coupled to the backrest 30 by means of a fixing frame 20 fastened threadingly to a bottom portion of the seat cushion 10 and a supporting frame 40 fastened threadingly to a rear side of the backrest 30. The fixing frame 20 bearing the seat cushion 10 and the supporting frame 40 holding up the backrest 30 are soldered together at overlapping sections thereof so as to form a one-piece unit, as shown in FIGS. 1 and 2. When the seat cushion fixing frame 20 and the backrest supporting frame 40 soldered together as an individual finished component are packaged for shipment, a large package volume and consequently high transportation costs will occur as the two frames are not detachable from each other.
  • BRIEF SUMMARY OF THE INVENTION
  • In view of the inconvenience of the seat cushion fixing frame and the backrest supporting frame of the conventional chair in terms of fabrication, packaging, and transportation, the present invention provides an improvement in which a seat cushion fixing frame and a backrest supporting frame are fabricated as separate components detachable from each other for packaging so as to effectively reduce package volumes thereof, to facilitate stacking during transportation, and to lower transportation costs, and in which the seat cushion fixing frame and the backrest supporting frame are assembled together and securely positioned relative to each other by a simple fastening operation.
  • A primary objective of the present invention is to provide a chair including a seat cushion fixing frame and a backrest supporting frame which are fabricated as separate components. Therein, the seat cushion fixing frame has an end coupled with an upside-down square U-shaped element bilaterally provided with downwardly extending sections, each section concavely provided with an oblique notch. The backrest supporting frame has an end which corresponds in position to the seat cushion fixing frame and is penetrated by and fixedly provided with a bar to be received in the oblique notches of the upside-down square U-shaped element of the seat cushion fixing frame during assembly. In addition, a resilient assembly is assembled to a bottom portion of a slot provided penetratingly at a predetermined position of a horizontal section of the backrest supporting frame. The seat cushion fixing frame, the backrest supporting frame, and the resilient assembly can be assembled rapidly without using tools. Furthermore, the seat cushion fixing frame and the backrest supporting frame are detachable from each other for packaging so as to effectively reduce package volumes thereof, to facilitate stacking during transportation, and to lower transportation costs.
  • BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
  • The invention as well as a preferred mode of use, further objectives, and advantages thereof will be best understood by referring to the following detailed description of an illustrative embodiment in conjunction with the accompanying drawings, wherein:
  • FIG. 1 is a side view of a conventional chair assembly including a seat cushion fixing frame and a backrest supporting frame;
  • FIG. 2 is a perspective view of the conventional chair assembly depicted in FIG. 1;
  • FIG. 3 is a side view of a seat cushion fixing frame, a backrest supporting frame, and a resilient assembly according to the present invention;
  • FIG. 4 is an exploded view of the seat cushion fixing frame, the backrest supporting frame, and the resilient assembly according to the present invention; and
  • FIG. 5 is an exploded perspective view of the seat cushion fixing frame, the backrest supporting frame, and the resilient assembly according to the present invention.
  • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to FIG. 4 and FIG. 5, a chair capable of a reduced transportation volume and rapid assembly according to the present invention includes a seat cushion fixing frame 1 and a backrest supporting frame 2 which are fabricated as separate components.
  • The seat cushion fixing seat 1 has a bottom portion provided with a pneumatic lifting assembly 11 corresponding in position to the center of gravity of the seat cushion fixing frame 1. (The pneumatic lifting assembly 11 is not a technical feature of the present invention and therefore is not described in detailed herein.) The seat cushion fixing seat 1 further has an end coupled with an upside-down square U-shaped element 12 bilaterally provided with downwardly extending sections, wherein each section is concavely provided with an oblique notch 121.
  • The backrest supporting frame 2 has an end which corresponds in position to the seat cushion fixing frame 1 and is penetrated by and fixedly provided with a bar 21 to be received in the oblique notches 121 of the upside-down square U-shaped element 12 of the seat cushion fixing frame 1 during assembly, as shown in FIG. 3.
  • In addition, a slot 22 is provided penetratingly at a predetermined position of a horizontal section of the backrest supporting frame 2. A resilient assembly 3 is assembled to a bottom portion of the slot 22. The resilient assembly 3 includes an upper connecting element 31, a resilient element 32, a washer 33, and a lower connecting element 34, as shown in FIG. 4.
  • FIG. 5 illustrates how the seat cushion fixing frame 1, the backrest supporting frame 2, and the resilient assembly 3 are assembled together. To begin with, the bar 21 fixedly provided at the end of the backrest supporting frame 2 is put into the oblique notches 121 of the upside-down square U-shaped element 12 of the seat cushion fixing frame 1, as shown in FIG. 3. Then, the resilient assembly 3 is placed against the bottom portion of the slot 22 provided penetratingly in the horizontal section of the backrest supporting frame 2. A screw 35 is passed sequentially through a hole 13 formed in the seat cushion fixing frame 1 and corresponding in position to the slot 22 formed in the horizontal section of the backrest supporting frame 2 and a central portion of the resilient assembly 3, before the screw 35 is fastened with the lower connecting element 34. Thus, the seat cushion fixing frame 1, the backrest supporting frame 2, and the resilient assembly 3 are rapidly assembled into a one-piece unit without using any tools.
  • Referring to FIG. 4, when the seat cushion fixing frame 1, the backrest supporting frame 2, and the resilient assembly 3 are to be packaged for shipment, the seat cushion fixing frame 1 and the backrest supporting frame 2 are detachable from each other so as to be packaged separately in small volumes, thus allowing the various components to be stacked up during transportation to lower transportation costs.
