Description
- 1. Field of the Invention
- The present invention relates to a collapsible frame and more particularly to a collapsible shade frame.
- 2. Description of the Related Art
- A shade or the like may provide a shield from the sun or rain for outdoor activities. A typical shade includes a frame and a canopy mounted on top of the frame. To avoid from being blown away by strong winds, the shade frame must have sufficient strength and stability. Further, the shade frame is preferably collapsible to allow easy carriage to the outdoors. However, conventional shade frames have complicated structures and are thus not advantageous to assembly while having a high cost. Further, the conventional shade frames are bulky and thus inconvenient to transport.
- A collapsible shade frame in accordance with the present invention includes a top frame and a leg assembly. The top frame includes a central coupler, a plurality of corner coupler, a plurality of supporting rods, and a plurality of connecting rods. The central coupler includes a cruciform body having four arms. Each arm includes a groove in an underside thereof. Each lower coupler includes a body having a central recess and two side recesses. A coupling section extends downward from the body and includes a groove in an underside thereof.
- Each connecting rod includes two ends that are respectively and pivotally mounted in two side recesses respectively of two adjacent corner couplers. Each supporting rod includes a first end pivotally mounted in the groove of an associated arm of the central coupler. Each supporting rod further includes a second end pivotally mounted in the central recess of an associated corner coupler. The leg assembly includes a plurality of legs each having an upper end releasably engaged in the groove of the body of an associated corner coupler.
- Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
-
FIG. 1 is a perspective view, partly exploded, of a collapsible shade frame in accordance with the present invention. -
FIG. 2 is a perspective view of the collapsible shade frame in accordance with the present invention in an extended state. -
FIG. 3 is a perspective view illustrating a portion of the collapsible shade frame in accordance with the present invention. -
FIG. 4 is a top view of a central portion of the collapsible shade frame in accordance with the present invention. -
FIG. 4A is an enlarged view of a circled portion inFIG. 4 . -
FIG. 5 is a sectional view taken along plane 5-5 inFIG. 4 . -
FIG. 6 is a schematic view, partly cutaway, illustrating pivotal movement of connecting rods of the collapsible shade frame. -
FIG. 7 is a plan view illustrating the collapsible shade frame in a fully collapsed state. - Referring to
FIGS. 1 and 2 , a collapsible shade frame in accordance with the present invention comprises a top frame 1 and aleg assembly 2. Acanopy 3 is mounted to the top frame 1 to form a shade. In this embodiment, the top frame 1 is substantially a pyramid with four sides such that thecanopy 3 is in the form of an umbrella when the top frame 1 is in an extended state. Nevertheless, the top frame 1 may be a pyramid having at least three sides. - Referring to
FIGS. 1 and 3 , the top frame 1 includes an upper,central coupler 11, four lower,corner couplers 12, four connectingrods 14, and four supportingrods 13. Referring toFIGS. 4 and 5 , theupper coupler 11 includes abody 111 that is substantially cruciform and that has fourarms 112 each having a bottom side with agroove 113 for pivotal connection with an associated supportingrod 13. - Each
corner coupler 12 comprises a substantiallysectorial body 121 including a plurality ofrecesses 122 each having an opening. In this embodiment, eachcorner coupler 12 includes acentral recess 122 and twoside recesses 122. Acoupling section 123 extends downward from thebody 121 and includes agroove 124 in an underside thereof. - Each supporting
rod 13 includes afirst end 131 pivotally mounted in thegroove 113 of an associatedarm 112 of thecentral coupler 11 by apin 15. Each supportingrod 13 further includes asecond end 132 pivotally mounted in thecentral recess 122 of an associatedcorner coupler 12 by apin 16. Thus, the supportingrods 13 extend radially from thecentral coupler 11. - Each connecting
rod 14 includes first andsecond ends side recesses 122 respectively of twoadjacent corner couplers 12 bypins 17. Namely, the connectingrods 14 form a perimeter of the top frame 1, best shown inFIG. 4 . In this embodiment, each connectingrod 14 includes afirst section 143 and asecond section 144. Referring toFIGS. 3 and 4 , thefirst section 143 includes apin 145 that is biased by a spring (not shown) and thesecond section 144 includes ahole 146 for releasably receiving the spring-biased pin 145, thereby allowing engagement or disengagement of the first andsecond sections second sections second sections pins 17, as shown inFIG. 6 . - The
leg assembly 2 includes fourlegs 21 each having anupper end 211 removably engaged in the groove 124 (seeFIG. 5 ) in thecoupling section 123 of an associatedcorner coupler 12. Eachleg 21 further includes alower end 212 to which a pad 215 (seeFIG. 1 ) is attached. In this embodiment, eachleg 21 includes anupper section 213 and alower section 214. Theupper section 213 includes a pin 216 (seeFIG. 3 ) that is biased by a spring (not shown) and thelower section 214 includes a hole 217 (seeFIG. 3 ) for releasably receiving the spring-biased pin 216, thereby allowing engagement or disengagement of the upper andlower sections - The shade frame in accordance with the present invention is simple in structure and has sufficient strength by providing four supporting
rods 13 radially extending from thecentral coupler 11, four connectingrods 14 between thecorner couplers 12, and fourlegs 21 below thecorner couplers 12. - Since the supporting
rods 13 are pivotally connected to thecentral coupler 11 and thecorner couplers 12 and since the connectingrods 14 are pivotally connected between thecorner couplers 12, the supportingrods 13 and the connectingrods 14 can be collapsed after theleg assembly 2 is detached (seeFIG. 7 ), allowing easy assembly and easy transport and/or storage of the shade frame. It is noted that the first andsecond sections rod 14 and eachleg 21 may include more than two sections. - Although a specific embodiment has been illustrated and described, numerous modifications and variations are still possible without departing from the essence of the invention. The scope of the invention is limited by the accompanying claims.
