(22) FIG. 1 shows a general structure of a large container including a lid 1, a base 2, side plates 3,4,5,6 and a small door 7. When the lid 1 is placed on the side plates, the edgeguard around the lid will contact (surround) the outer surfaces of side plates 3,4,5,6 so as to improve the strength of the entire container. A large container generally refers to a container which has a volume of 250 L or more.
(23) FIG. 2 shows the container provided with the lid hanging structure of the present invention with the lid 1 being hung on the side plate 6. The lid hanging structure includes a bearing pin and a hanging slot (or a hanging hook). The lid 1 can slid on the side plates using the bearing pin so as to open or close the container. Further, the bearing pin may be engaged with the hanging slot (or the hanging hook) so as to hang the lid on the side plates. Wherein the bearing pin can be provided on the lid or on the side plates, or installed on the side plates as a separate member when used. The hanging slot can be provided on the side plates or on the lid, which will be described in more detail hereinafter. It should be noted that, at least one part of the edgeguards 14, 15 of the lid 1 will contact or be close to the outer surfaces of the side plates when the lid 1 is hung on the side plate 6 or slides along the container. Therefore, the configuration of the edgeguards 14, 15 and the side plates 3, 5 will limit the range of the shaking of the lid 1 when the lid 1 slides along the container, so that the lid 1 can slide steadily.
(24) FIG. 3a-5b show schematic views of the lid hanging structure of a large container according to the first embodiment of the present invention. As shown in FIG. 3a-5b, the lid hanging structure includes a hanging slot provided on the lid 1, a hanging member 8 as a separate member, and a mating structure provided on a side plate engaging with the lid 1, wherein the mating structure enable the lid 1 and the hanging member 8 to be engaged so as to open or close the lid or hang the lid on the side plates.
(25) Hereinafter, the lid 1, the mating structures provided on the side plate 6, the hanging member 8 and the engagement among them will be described in further detail. FIGS. 3a-3c show the structure of the lid 1 according to the embodiment. As shown in FIGS. 3b and 3c, a groove 12 is provided on the left end of the lid 1. A slope 122 is provided at outer side of the groove 12 and a dimple 121 is provided inside the groove 12, wherein an arced contour is provided on the bottom of the dimple 121. A hanging slot 11 is provided on the bottom of the lid 1 near the middle of one edge of the lid and slightly close to right end thereof. A pit 112 is provided in the hanging slot 11 and the mouth of the pit 112 is provided with a slop 111. Further, a rib 13, which is provided on the bottom of the lid 1 and close to the edgeguard, is cut off at the left and right end of the hanging slot so as to forming slopes 131, 132 respectively. In addition, a slope 133 is further provided on the left end of the rib 13.
(26) FIG. 4 is a perspective view of the hanging member 8 with a torsional spring 9 thereon. The hanging member 8 comprises a rotation pin 83, a bearing pin 81, a position limiting pin 82 and a position limiting pin 84, wherein the position limiting pin 84 is further provided with a projection 841. The function of the projection 841 will be described in detail in the following. The torsional spring 9 is installed on the rotation pin 83.
(27) FIG. 5 is a partial side view of the side plate 6, which has two pits 61 on both ends of its upper portion, wherein a circular hole 63 and a special-shaped through-hole 64 with a special arced contour 641 are provided at each pit 61. A stopping edge 65 is provided on the left of the circular hole 63. When mounting the locking member 8 to the side plate 6, the rotation pin 83 is inserted partly into the circular hole 63 firstly and the projection 841 of the position limiting pin 84 is aligned with the arced contour, then the locking member 8 can be completely mounted. After installation of the locking member 8, the position limiting pin 82 is located in the position limiting hole 62. The locking member 8 will lean against the stopping edge 65 since the torsional spring 9 will applied a counterclockwise torque to the locking member 8 continually. Now, the locking member will not able to be released due to the deviation of the arced contour 641 from the projection 841. The locking member can be released only in the case that the projection 841 of the position limiting 84 is aligned with the arced contour 641.
(28) FIG. 6a-6c shows the process of the hanging member 8 entering the groove 12 when the lid 1 is placed on the side plates from directly above the side plates. The slope 122 will contact with the bearing pin 81 of the hanging member 8 firstly, and the hanging member 8 will be forced to rotate an angle clockwise around its rotation pin 83 due to the pressure applied by the slope 122, which makes the bearing pin 81 to leave the location under the groove 12. The bearing pin 81 faces exactly to the dimple 121 of the groove 12 when the lid 1 is in place. Then, the hanging member 8 will rotate counterclockwise around the rotation pin 83 due to the restore of the torsional spring 9, so that the bearing pin 81 enters into the dimple 121, thereby limiting the upward movement of the lid 1.
(29) FIGS. 7-10 show the process that the lid 1 moves from the using state to the hanging state. When the lid 1 is opened by a distance from its left side, i.e. from the side plate 4, the lid 1 rotates by a certain angle around a position where the lid 1 contacts with the left and upper portion of the side plate 6. Then, as shown in FIG. 7, the bearing pin 81 of the hanging member 8 will be released from the groove 12 when continuing to push the lid 1 forward. The position where the bearing pin 81 contacts the lid 1 is changed from the lid itself to the rib 18 by the slope 133 provided on the rib 13, so as to reduce friction during the process of sliding of the lid. And the right side of the lid 1 needn't to be lifted up by hand through contacting the lower portion of the edgeguard with the upper portion of the side plates 3, 5. The lid will slid to a position where the slope 131 will not contact with the bearing pin 81, as shown in FIG. 8. Then, the lid 1 itself will contact with the upper portion of the right end of the side plate 6 and the pit 112 is ready to accommodate the bearing pin 81.
(30) As shown in FIG. 9, the bearing pin 81 will sliding into the pit 112 of the hanging slot 11 easily due to the guide of the slope 111 when pushing the lid 1 forward continuously. The lid 1 can't move forward any further at the moment since the centre of gravity of the lid 1 has already arrived at the outside of the container and there is a trend that the lid 1 will rotate downward. As shown in FIG. 10, the lid 1 will rotate outward around the bearing 81. When the lower part of the left edgeguard of the lid 1 contacts the side plate 6, the lid 1 can't move anymore so that the lid is hung on the side plate 6. The pit 61 of the side plate 6 will accommodate the hanging slot 11 provided on the lid 1.
(31) The lid 1 can be removed from the side plates through being opened and moved by a distance. The lid 1 can also be removed from the side plates in the hanging state. As shown in FIG. 11, when the lid 1 is in the hanging state, the bearing 81 will leave the pit 112 when lifting the lid 1 upward, so as to remove the lid 1 from the side plates.
(32) Further, as compared to the above embodiments, there is a more simple way in the second embodiment. As shown in FIGS. 12-14, if the lid 1 is provided with a specific structure for locking to the upper of the side plate 6 to limit the upward movement of the lid 1 when the lid 1 is in use, i.e. the lid is placed on the side plates, the pits 12 can be cancelled and the hanging member 8 is simplified as a bearing pin 66 provided on the side plate 6 or installed on the plate 6 as a separate pin.
(33) It can be understood that in the above two embodiments, the bearing pin can be installed on the side plates as a separate member or as a part of the side plate (as shown in the second embodiment) when the bearing pin is connected to a side plate. The bearing pin may have another function, such as locking function described in the first embodiment when the lid is in use, if the bearing pin is a separate member.
(34) FIG. 15-18 show a lid hanging structure according to the third embodiment. The difference between the third embodiment and the second embodiment is that, a bearing pin 16 of the lid hanging structure is provided on the bottom of the lid 1 near the middle of one edge of the lid and slightly close to right end thereof as a part of the lid 1. As shown in FIG. 15, a projection is provided between the ribs 13 provided on the lid 1 and the bearing pin 16 is provided on a side surface of the projection.
(35) As shown in FIGS. 16a and 16b, two hanging slot 66 are provided on both ends of the upper portion of the side plate 6 respectively. A pit 661 facing the left is provided in the hanging slot 66 and a slope 662 is provided on the upper wall of the pit 661. The slope 662 will guide the bearing pin 16 into the pit 661 when the lid is opened and slides forward. The lid 1 may be slightly rotated toward the inside and then pushed back by a distance so as to be disengaged from the side plates and removed.
(36) Although all above embodiments are different from each other, the same is that, the bearing pin is not always in the hanging slot. Only in the hanging position or being close to the hanging position, the bearing pin is connected to the hanging slot. The advantage is that the lid can be removed from the side plates easily. That is to say, the lid can be removed directly when not in use or in the hanging state, and can be removed by simple operation in the hanging state, so as to reduce the amount of labor, and the structure is simple and the cost is low.
(37) Preferred embodiments of the present invention has been described in detail above, while it is to be understood that, after reading the above teachings of the present invention, those skilled in the art may make various modifications or amendments to the present invention. These equivalent forms still fall into the scope limited by appended claims of the present application.
