With the joint 113, the collapsible frame is collapsible about an axis Z.


The third bone 13 includes two lateral segments 131 and 132 between two horizontal segments 133 and 134. The horizontal segment 133 is formed with two bosses 135. The lateral segments 131 and 132 are in perpendicular to the horizontal segments 133 and 134. Therefore, the third bone 13 includes a substantially rectangular configuration. A bent segment 20 extends between the horizontal segment 134 and each of the lateral segments 131 and 132. The bent segments 20 are used as feet for contact with the ground or a floor.


Similarly, the fourth bone 14 includes two lateral segments 141 and 142 between two horizontal segments 143 and 144. The horizontal segment 143 is formed with two bosses 145. The lateral segments 141 and 142 are in perpendicular to the horizontal segments 143 and 144. Therefore, the fourth bone 14 includes a substantially rectangular configuration. A bent segment 20 extends between the horizontal segment 144 and each of the lateral segments 141 and 142. The bent segments 20 are used as feet for contact with the ground or the floor.


The lateral segment 131 of the third bone 13 and the lateral segment 141 of the fourth bone 14 are pivotally connected to a tip of a related one of the vertical segments of the first bone 11 with a joint 111 as clearly shown in FIG. 5. Similarly, the lateral segment 132 of the third bone 13 and the lateral segment 142 of the fourth bone 14 are pivotally connected to a tip of the other vertical segment of the first bone 11 with a joint 112. The joints 111 and 112 are identical. With the joints 111 and 112, the collapsible frame is collapsible about an axis X.


The fifth bone 15 is an inverted U-shaped bone including a horizontal segment 151 extending between two lateral segments. The horizontal segment 151 of the fifth bone 15 is in perpendicular to the lateral segments of the fifth bone 15.


The sixth bone 16 is also an inverted U-shaped bone including a horizontal segment 161 extending between two lateral segments. The horizontal segment 161 of the sixth bone 16 is in perpendicular to the lateral segments of the sixth bone 16.


One of the lateral segments of the fifth bone 15 and a related one of the lateral segments of the sixth bone 16 are pivotally connected to a tip of a related one of the vertical segments of the second bone 12 with a joint 121. Similarly, the other lateral segment of the fifth bone 15 and the other lateral segment of the sixth bone 16 are pivotally connected to a tip of the other vertical segment of the second bone 12 with a joint 122. The joints 121 and 122 are identical. With the joints 121 and 122, the collapsible frame is collapsible about an axis Y.


Referring to FIG. 7, a connecting device detachably connects the horizontal segment of the second bone 12 to the horizontal segment 134 of the third bone 13. Another connecting device detachably connects the horizontal segment of the second bone 12 to the horizontal segment 144 of the fourth bone 14. Each of the connecting devices includes a hook 17 extending from each end of the horizontal segment of the second bone 12. One of the hooks 17 hooks the horizontal segment 134 of the third bone 13. The other hook 17 hooks the horizontal segment 144 of the fourth bone 14.


Referring to FIG. 8, a connecting device detachably connects the horizontal segment 151 of the fifth bone 15 to the lateral segment 131 of the third bone 13. Another connecting device detachably connects the horizontal segment 151 of the fifth bone 15 to the lateral segment 141 of the fourth bone 14. Another connecting device detachably connects the horizontal segment 161 of the sixth bone 16 to the lateral segment 131 of the third bone 13. Another connecting device detachably connects the horizontal segment 161 of the sixth bone 16 to the lateral segment 141 of the fourth bone 14.


Each of the connecting devices includes a hook 17 extending from each end of each of the horizontal segments 151 and 161. A space 18 is hence defined by each of the hooks 17 and a related one of the lateral segments of a related one of the bones 15 and 16. Each of the spaces 18 receives a related one of the lateral elements 131, 132, 141 and 142. The bosses 135 and 145 prevent the hooks 17 from sliding along the horizontal segments 133 and 143. In addition, a movable restraining element 19 can be used to retain the lateral elements 131, 132, 141 and 142 within the spaces 18.


The collapsible frame can be moved between an extended position as shown in FIG. 1 and a collapsed position as shown in FIG. 2. Obviously, it takes a small space and costs a little money in storing and transporting the collapsible frame.


To collapse the collapsible frame, the restraining elements 19 are removed from the bones 15 and 16 as shown in FIG. 2. Then, the bones 13 and 14 are pivoted towards each other about the axis X for a small angle and released from the hooks 17. Then, the bones 15 and 16 are pivoted towards each other about the axis Y and located against each other as shown in FIG. 3. Then, the second bone 12, together with the bones 15 and 16, is pivoted on the first bone 11 about the axis Z. Thus, the bones 11 and 12 are substantially in a same plane. The bones 13 and 14 are further pivoted towards each other about the axis X and finally located against each other.


To extend the collapsible frame, the bones 11 and 12 are opened so that there is an angle of 90 degrees between the horizontal segment of the first bone 11 and the horizontal segment of the second bone 12. The bones 13 and 14 are opened so that the lateral segment 131 and the lateral segment 141 form a X-shaped structure and that the lateral segment 132 and the lateral segment 142 form another X-shaped structure. The bones 15 and 16 are opened so that each of the lateral segments of the fifth bone 15 and a related one of the lateral segments of the sixth bone 16 form a V-shaped structure. Finally, the horizontal segments 151 and 161 are connected to the horizontal segments 133 and 143.


Referring to FIG. 13, the bag 30 includes four extensive portions 31 extending from an edge around an open end thereof. Each of the extensive portions 31 is wound around a related one of the horizontal segments 133, 143, 151 and 161. Thus, the bag 30 is opened and supported on the collapsible frame, and things can easily be tossed into the bag 30.


Referring to FIGS. 9 through 12, there is shown a collapsible frame according to a second embodiment of the present invention. The second embodiment is like the first embodiment except a few things. Firstly, each of the bones 15 and 16 extends in an arch instead of along an inverted U-shaped path. Secondly, there is a seventh bone 133 instead of the horizontal segment 133 of the third bone 13. Thirdly, there is an eighth bone 143 instead of the horizontal segment 143 of the fourth bone 14. Each of the bones 133 and 143 extends in an arch. Each end of the seventh bone 133 is pivotally connected to an end of the eighth bone 143 with a joint 21. The bones 133 and 143 form a circular structure as the collapsible frame is in the extended position. The circular structure is detachably connected to each of the bones 15 and 16 with a clip 19. Each of the clips 19 includes a lower arched portion for hooking a related one of the bones 15 and 16 and two upper arched portions 191 each for hooking a related one of the bones 133 and 143. Each of the lower and upper arched portions looks like a “C” from an end. The seventh bone 133 is pivotally connected to each of the lateral segments 131 and 132 of the third bone 13 with a joint. The eighth bone 143 is pivotally connected to each of the lateral segments 141 and 142 of the fourth bone 14 with another joint. An end of each of the bones 133 and 143 is pivotally connected to a middle point 151 of the fifth bone 15. Another end of each of the bones 133 and 143 is pivotally connected to a middle point 161 of the sixth bone 16. The collapsible frame can be moved between an extended position as shown in FIG. 3 and a collapsed position as shown in FIG. 4.
