The present invention relates to a foldable appliance, and more particularly to a foldable container with foldable supporting frame and folding method thereof.
Many foldable brackets are designed and aid for daily entertainment activities. Accordingly, a height of the bracket can be raised to lift up the appliance from the ground during the use of the appliance. As a result, the user does not have to bend or squat to use the appliance. Once the bracket is folded, a size of the bracket is reduced for storage and space saving.
Household temporary container, especially large size receptacle, is popular to be used as basin, bathtub or swimming pool for bathing, cleaning or playing purpose. This temporary container is convenient for most families. For example, the user is able to move this temporary container from place to place, such as bathroom or yard, as needed. Since this kind of container needs to have space large enough to hold at least a child or pet inside while having enough space to contain water or cleaning liquid, the conventional container is generally made in larger size. This kind of rigid container is convenient for most families also take wider space for using water, usually in outdoor area or bathroom. It is known that such relatively large container is not required to be used all the time or even daily use, this temporary container will not be the primary consideration for most families in view of storage, especially for urban families. Since the storage in urban family is very limited, it is a problem to store the temporary container when it is not in used. These defects of the temporary container cannot be solved and this temporary container is not practical in use.
Specifically, in order to reduce the space occupied by the temporary container when it is not in use, the current temporary container is designed to be inflatable, such that the temporary container is reused by inflating and deflating the temporary container. Usually, the temporary container is inflated by an inflator or inflatable pump. Before using the inflatable temporary container, it is necessary to initially place the inflatable temporary container in a preset position, and then use the inflatable pump to inflate the inflatable temporary container for at least five minutes for fully inflate the temporary container by filling a predetermined amount of gas to bias against the inner sidewall of the temporary container so as to support the shape of the temporary container. In other words, it is very troublesome to setup the temporary container. If the inflatable pump is damaged or lost, the inflatable temporary container cannot be used at all. Moreover, in order to facilitate the temporary container being folded after deflation, it is also necessary to provide an air exhaust vent at the temporary container. If the air exhaust vent is poorly sealed, air leakage is likely to occur. Once the inflatable temporary container has an air leakage problem, it is easy to cause the water or cleaning liquid contained in the temporary container to leak out, especially for the temporary container used in the living room. In other words, if the water or cleaning fluid leaks out of the temporary container, it will inevitably cause water damage to the home environment. Furthermore, during the manufacturing process of the inflatable temporary container, the air exhaust vent is affixed to the sidewall of the temporary container to communicate with an interior air chamber of the inflatable temporary container. It is difficult to ensure the tightness between the sidewall and the air exhaust vent.
For the temporary container made of plastic, it must be stored indoors in order to prevent the plastic aging from directly exposing under the sun. Therefore, it is necessary to save a larger space for storing the temporary container. In some cases, the entire temporary container is used to store various items inside the container during storage, such that these items must be placed somewhere in the storage room. However, before the next use of the temporary container, additional steps are required to take out the items and clean the container before use.
In addition to liquid containers, some cooking utensils, such as grills, table tops, etc., have similar problems. One of the major problems is stability after it is setup. Since the foldable bracket is movable, it is a major concern how to keep the stability of the foldable bracket when it is unfolded. The existing foldable bracket is basically constructed to have a X-shaped pivotal structure. This structure provides high mobility and is easy to deform during use. The foldable angle may increase permanently as the structure is frequently used.
In addition, the temporary container is directly placed on the ground when it is used, wherein the user will need to bend over when helping children or pets to clean, which is likely to hurt health the user, especially the back of the user.
Even though the existing foldable brackets can be folded, the folding operation thereof requires many steps. Basically, it requires two hands to close the bracket, and may also need to rotate and fold different parts of the bracket frame. So, the traditional folding process of the foldable bracket is very troublesome. Since the folding process is complicated and difficult, the user will merely keep the temporary container being unfolded all the time, which fails to achieve the main purpose of folding up the temporary container for storage to save the space.

Referring to
Preferably, when the foldable supporting frame 10 is unfolded, the container body 30 is automatically unfolded along with the folding operation of the foldable supporting frame 10. In other words, during the folding process of the foldable supporting frame 10, the container body 30 is automatically folded when the foldable supporting frame 10 is folded. Preferably, the foldable supporting frame 10 is a rigid frame that is made of a material selected from the group consisting of wood, metal, metal alloy, and plastic. Metal of the material of the foldable supporting frame 10 may be Iron, Copper, or Aluminium. The container body 30 is preferably a flexible body that is made of a flexible water-proof material such as PE (Polyethylene), PVC (Polyvinyl Chloride), PP (Polypropylene) and TPU (Thermoplastic Urethanes). Accordingly, the flexible container body 30 is constructed to be easy to be folded up with a folding of the foldable supporting frame 10 and unfolded with an unfolding of the foldable supporting frame 10, when the foldable supporting frame 10 is unfolded, the foldable supporting frame 10 is supported in the unfolded mode by the operation switch 20 to provide a rigid support to the container body 30, and the operation switch 20 is able to be operated to release the rigid support of the foldable supporting frame 10 when the foldable supporting frame 10 is operated from the unfolded mode to the folded mode.
It is worth mentioning that the present invention provides a single pulling operation referring to the one-way mode when the foldable container is operated to moved and converted from the unfolded mode to the folded mode. In other words, operating the foldable container at the same direction can move the foldable container from the unfolded mode to the folded mode. Preferably, the single pulling operation in the present invention refers to the one-way pulling operation when operating the foldable container to move from the unfolded mode to the folded mode. In other words, pulling the foldable container at the same direction at one time can move the foldable container from the unfolded mode to the folded mode. It is appreciated that those skilled in the art should understand that pulling the foldable container at the same direction in different stages can also move the foldable container from the unfolded mode to the folded mode. For example, pulling the foldable container twice toward the same direction can also move the foldable container from the unfolded mode to the folded mode. As shown in
As shown in
It is worth mentioning that the folding arms 12 are pivotally connected to each other by the operation switch 20. The rotation of the folding arm 12 is configured to drive the folding or unfolding movement of the top supporting arm 11 and the supporting leg 13. When the foldable supporting frame 10 is in the folded mode, the two folding arms 12 are arranged to be folded and overlapped each other. When the foldable supporting frame 10 is in the unfolded mode, the two folding arms 12 are arranged to be unfolded to open and extended flatly. Therefore, when the folding arm 12 is folded, the top supporting arm 11 and the supporting leg 13 are folded following the folding operation of the folding arm 12. Therefore, by only folding the folding arm 12, the entire foldable supporting frame 10 is folded, which is convenient in operation. When the foldable supporting frame 10 is folded, the container body 30 is correspondingly folded.
As shown in
Specifically, the two folding arms 12 are pivotally connected with each other around a rotating rod 121, wherein the rotating rod 121 is placed between the ends of the two folding arms 12. The rotating rod 121 is installed into the operation switch 20. The two folding arms 12 are rotated around the operation switch 20, wherein the operation switch 20 is configured to restrict the rotations of the folding arms 12 relative to each other. According to the first embodiment, one of the folding arms 12 is fixed to the operation switch 20, while another folding arm 12 is relatively free to rotate relative to the operation switch 20. In other words, one of the folding arms 12 is defined as a fixed folding arm 1202, and another folding arm 12 is a free rotatable folding arm 1201. The fixed folding arm 1202 is installed into the operation switch 20 together with the rotating rod 121. The free rotatable folding arm 1201 is rotatably coupled at the operation switch 20 around the rotating rod 121.
In addition, the rotation of the fixed folding arm 1202 and the free rotatable folding arm 1201 around the rotating rod 121 are asymmetrical. In other words, when the fixed folding arm 1202 and the free rotatable folding arm 1201 are folded with each other, the fixed folding arm 1202 and the free rotatable folding arm 1201 are staggered and stacked with each other and will not contact or collide with each other. On one side, the fixed folding arm 1202 and the free rotatable folding arm 1201 will not be mechanically damaged during the folding and unfolding operations. On the other side, after folding, a retention channel is formed between the fixed folding arm 1202 and the free rotatable folding arm 1201.
It is worth mentioning that the end of the free rotatable folding arm 1201 is further transversely connected to a switch rod 122. When the folding arm 12 is flatly unfolded, the switch rod 122 is firmly supported by the operation switch 20, wherein the free rotatable folding arm 1201 is parallel to the fixed folding arm 1202. When the switch rod 122 is supported, the free rotatable folding arm 1201 is relatively supported on the same side of the fixed folding arm 1202. When the operation switch 20 is configured to keep supporting the switch rod 122, the free rotatable folding arm 1201 is configured to remains relative parallel to the fixed folding arm 1202. When the switch rod 122 is released from the operation switch 20, the free rotatable folding arm 1201 will lose its support. Under the action of gravity force, the free rotatable folding arm 1201 will rotate around the rotating rod 121 and fold toward the fixed folding arm 1202. In other words, when the switch rod 122 is supported by the operation switch 20, due to the restriction of the operation switch 20, the folding arm 12 is unfolded and is difficult to change its position. Once the switch rod 122 is detached from the operation switch 20, the folding arm 12 can rotate around the rotating rod 121 to be folded. Therefore, the folding arm 12 is controlled by the operation switch 20 for controlling the movement of the folding arm 12, wherein the folding position or the unfolding position of the foldable supporting frame 10 is indirectly controlled by the operation switch 20.
In addition, the supporting legs 13 and the folding arms 12 are pivotally connected to pivot shafts 130 respectively. When the folding arm 12 is operated to rotate around the rotating rod 121, the angle and distance between the folding arms 12 are changed while the supporting leg 13 is driven to rotate around the pivot shafts 130. Each of the supporting legs 13, each of the folding arms 12, and the pivot shaft 130 are formed into a rotatable X-shaped frame. Since the movements of the folding arms 12 are transmitted to the supporting legs 13, the supporting legs 13 are automatically moved for being further folded or unfolded via the folding arms 12.
Furthermore, as shown in
Furthermore, the top supporting arm 11 is driven to rotate by the supporting leg 13 via a folding assembly 110, wherein the folding assembly 110 is installed at the top of the supporting leg 13. When the supporting leg 13 is folded or unfolded as the folding arm 12 rotates, the top supporting arm 11 is driven to rotate around the folding assembly 110. Each of the supporting legs 13, each of the top supporting arms 11, and the folding assembly 110 are formed into a rotatable inversed V-shaped frame. Since the folding assembly 110 is driven, it is not necessary to fold or unfold the supporting leg 13 because the movement of the folding assembly 110 will be transmitted to the supporting leg 13.
In detail, the folding assembly 110 comprises a rotatable base 111 and a linkage unit 112. The rotatable base 111 is coupled at the end of the top supporting arm 11 to receive the upper end of the supporting leg 13 in the rotatable base 111. The linkage unit 12 comprises two linkage members 1121 respectively mounted on the top end of the supporting leg 13 and the end of the top supporting arm 11. The linkage members 1121 are connected by link shafts 1122, so that the angle between each top supporting arm 11 and each supporting leg 13 can be controlled and has a maximum angle limitation. Each of the top supporting arms 11, each of the supporting legs 13 and the linkage member 1121 are formed in an A shape, wherein the top supporting arms 11 will drive the supporting legs 13 to move, while the supporting legs 13 will drive the top supporting arm 11 to move around the rotatable base 111.
Preferably, by operating the operation switch 20 to release the switch rod 122 and to fold the folding arm 12, the supporting leg 13 and the top supporting arm 11 are corresponding folded. Preferably, the top supporting arm 11 is expanded to further drive the folding arm 12 to be supported on the operation switch 20 and to drive the supporting leg 13 to expand.
Furthermore, each of the supporting legs 13 is configured for correspondingly installing an extension leg 14 for increasing the height of the top supporting arm 11 and keeping the container body 30 on the top supporting arm 11 in a preset position, as shown in
The container body 30 comprises a surrounding wall 31 and a bottom wall 32 sealingly connected to the surrounding wall 31 to form the container body 30 having a bowl shape and a surrounding edge 310 defining an opening thereof surrounded by the edge 310. The edge 310 of the surrounding wall 31 is disposed on the top supporting arm 11 of the foldable supporting frame 10. In one alternative mode of the present invention, the container body 30 is detachably mounted on the top supporting arm 11 for replacement. The container body 30 further comprises at least one pocket 33 placed on the surrounding wall 31. The pocket 33 is configured for keeping other items therein to facilitate the reaching of items when using liquid for cleaning or playing in the container body 30.
Preferably, as shown in
Specifically, the fixing rib 312 is extended into the fixing cavity 102 of the rod body 101, such that the edge sleeve 311 to be carried is suspended and fixed to the rod body 101. In the first embodiment, the fixing cavity 102 of the rod body 101 has a U-shaped configuration, wherein the fixing rib 312 is configured to enter from an opening of the fixing cavity 102 into the fixing cavity 102. Furthermore, the edge sleeve 311 is formed in a U-shape and is also connected to the rod body 101 of the top supporting arm 11 in a U-shape. When the surrounding wall 31 is needed to be disassembled, the fixing rib 312 relatively removed from the fixing cavity 102 of the rod body 101, wherein the fixing rib 312 is completely removed from the top supporting arm 11. Preferably, the rod body 101 is pulled to release the supportability of the edge sleeve 311. More preferably, the fixing rib 312 is detachably connected to the sleeve edge 311, such that the sleeve edge 311 can be further folded or cleaned.
It is worth mentioning that the bottom wall 32 has a drain port 322 for draining the water or cleaning liquid in the container body 30. Preferably, the drain port 322 is set at the lowest location or area of the bottom wall 32 for effectively draining the liquid in the container body 30. The drain port 322 is able to connect a drain pipe 40 to allow liquid to flow out of the container body 30 along the drain pipe 40. A drain plug can be detachably plugged at the drain port 322 to prevent the liquid being drained out the container body 30 through the drain port 322.
Particularly, as shown in
The bottom wall 32 further comprises a handle 321 connected to the operation switch 20. The operation switch 20 can be operated by operating the handle 321 to fold the folding arm 12.
As shown in
When the free rotatable folding arm 1201 is rotated, is supported by the slider 22, and is parallel to the fixed folding arm 1202, the folding arm 12 is unfolded flatly, while the folding supporting frame 10 is in the unfolded mode. When the slider 22 is configured to move back in the main body 21, the free rotatable folding arm 1201 is configured to drop and overlappedly fold with the fixed folding arm 1202.
According to the preferred embodiment, the main body 21 is formed with two fixed arm cavities 211, two free arm cavities 212 and a slider cavity 213. The end of the fixed folding arm 1202 is fixedly coupled in the fixed arm cavity 211, and the rotating rod 121 is configured to pass through the fixed arm cavity 211. The end of the free rotatable folding arm 1201 is movably arranged in the free arm cavity 212 and rotatably connected around the rotating rod 121. Therefore, the rotating rod 121 is configured to pass through the fixed arm cavity 211 and the free arm cavity 212. In other words, both ends of the free rotatable folding arm 1201 and both ends of the fixed folding arm 1202 surround the rotating rod 121. The fixed folding arm 1202 and the fixed arm cavity 211 of the main body 21 remain stationary, wherein the free rotatable folding arm 1201 is configured to rotate in the free arm cavity 212 of the main body 21. The slider 22 is movably disposed in the slider cavity 213 to be moved in or pushed by the resilient member 23 to move out of the slider cavity 213.
The switch rod 122 is located outside of the main body 21 and is configured to apply a pushing force to the slider 22 to move the slider 22 backward in the slider cavity 213. When the switch rod 122 is lifted to force the slider 22 to move in, and when the free rotatable folding arm 1201 is rotated around the rotating rod 121 to expand, the slider 22 is pushed to move back into the slider cavity 213. When the switch rod 122 passes over the slider 22 that no force is applied to the slider 22, the slider 22 is pushed out of the slider cavity 213 by the resilient member 213 to protrude out of the slider cavity 213 again. The switch rod 122 is then supported by the slider 22 when protrude out of the slider cavity 213. Under this circumstances, the switch rod 122 cannot push the slider 22 back, and the slider 22 bears the weight of the switch rod 122. When the slider 22 is kept protruding out of the slider cavity 213 and the switch rod 122 is still supported by the slider 22 of the operation switch 20, the free rotatable folding arm 1201 and the fixed folding arm 1202 are relatively unfolded, while the folding arm 12 is laid flat and stable.
The slider 22 has a supporting end 221 defining a unidirectional inclined sloping surface. The switch rod 122 is configured to push the supporting end 221 along the sloping surface thereof. The supporting end 221 of the slider 22 is configured to support the switch rod 122 on the planar surface thereof to bear the weight of the switch rod 122 so as to prevent the switch rod 122 being pushed back.
The slider 22 has a pulling end 222 firmly connected to a pulling strap 24. By pulling out the pulling strap 24, the slider 22 is configured to resist the elastic force of the resilient member 23 and to move backward in the slider cavity 213.
The slider 22 further comprises a stopper 223 protruded from the main body 21 to engage with the slider 22 inside the slider cavity 213 for preventing the slider 22 from moving out of the slider cavity 213 via the pushing force of the resilient member 23. In other words, the slider 22 is pushed by the resilient member 23 and is held by the stopper 223 in order to be held in the slider cavity 213. Also, the slider 22 is restricted to move along a specific path in the slider cavity 213. According to the preferred embodiment, the slider 22 further comprises at least one slide rail 2134 formed inside the slider cavity 213 to limit the moving direction and distance of the slider 22. The slider 22 further comprises at least one sliding leg 224, wherein the sliding leg 224 is correspondingly engaged with the sliding rail 2134 of the sliding block cavity 213.
The slider cavity 213 has a supporting opening 2131 corresponding to the free rotatable folding arm 1201 and a pulling opening 2132 corresponding to the fixed folding arm 1202. The slider 22 is pushed by the resilient member 23 to protrude out from the supporting opening 2131, wherein when the slider 22 is pressed by the switch rod 122, the slider 22 is pulled back toward the pulling opening 2132. The slider cavity 213 further has a limitation window 2133. The limitation window 2133 is preferably located at the top of the main body 21. The limitation window 2133 is configured to accommodate the stopper 223 of the slider 22 inside the limitation window 2133. The limitation window 2133 is configured to block the stopper 223 and move within the area of the limitation window 2133. In other alternative modes, the limitation window 2133 can be shaped as a groove to limit the movement of the stopper 223.
The pulling strap 24 is extended out of the main body 21 through the pulling opening 2132 from the pulling end 222 of the sliding block 22. When the pulling strap 24 is actuated to pull the slider 22 back to the slider cavity 213, the supporting end 221 is moved backward, such that the support of the switch rod 122 is dismissed due to the backward movement of the supporting end 221. The stopper 223 is restricted to continuously move backward by the limitation window 2133, so as to avoid further movement of the slider 22.
The pulling strap 24 has one end connecting to the handle 321 at the bottom wall 21 of the container body 30 and an opposed end connecting to the slider 22. Therefore, when the handle 321 is pulled to lift the container body 30, the pulling strap 24 is configured to transmit the pulling force to pull the slider 22 to move the slider 22 into the slider cavity 213. Only one action of pulling the handle 321 of the container body 30 is required for operating the operation switch to fold the foldable supporting frame 10.
In addition, the relationship and movement of the foldable container during the unfolding process according to the preferred embodiment are shown in
When the foldable container is actuated for being used, as an example, the top supporting arms 11 are opened from the folded mode. The top supporting arms 11 are configured to drive the supporting legs 13 to move and expand around the folding assembly 110. The supporting legs 13 are configured to drive the folding arms 12 to open about the pivot shafts 130. In other words, the folding arms 12 are driven to rotate about the pivot shafts 130 by the movements of the supporting legs 13. When the folding arms 12 are unfolded to lay flat on each other, the folding arms 12 are rotated about the rotating rod 121. The folding arm 12 will be supported by the operation switch 20 to restrict its further movement.
Specifically, when the free rotatable folding arm 1201 is rotated to the fixed folding arm 1202, the free rotatable folding arm 1201 is rotated to be supported by the slider 22 of the operation switch 20 and is parallel to the fixed folding arm 1202, such that the folding arms 12 are expand to lay flat on each other. The foldable support frame 10 is in the unfolded mode. When the free rotatable folding arm 1201 is driven to rotate, the switch rod 122 is lifted to apply the force to the supporting end 221 of the slider 22. Then the slider 22 is pushed to move back into the slider cavity 213. After the switch rod 122 is continuously raised to pass over the slider 22, the slider 22 is not affect by the force, such that the slider 22 is pushed out of the slider cavity 213 by the resilient member 23 to protrude out of the slider cavity 213. The switch rod 122 is supported on the slider 22 when the slider 22 is protruded out of the slider cavity 213. Under this circumstance, the switch rod 122 cannot push the slider 22 back by exerts its weight on the slider 22. Therefore, the folding arm 12 is unfolded and is stably supported by the switch 20. The foldable support frame 10 is moved at its unfolded mode. The container body 30 is opened up as the top supporting arms 11 are expanded.
Accordingly, as the top supporting arm 11 of the foldable support frame 10 is unfolded, the folding arm 12 is stably supported by the operation switch 20. Furthermore, under the movement of the top supporting arm 11, the container body 30 is actuated to be opened.
In addition, the relationship and movement of the foldable container during the folding process according to the preferred embodiment are shown in
In order to fold the foldable container, the handle 321 is pulled to lift the container body 30, such that the pulling strap 24 will transmit a pulling force to pull the slider 22 to move back in the slider cavity 213. When the folding arm 12 is unfolded, the supporting end 221 will support the switch rod 122 on its planar surface to bear the weight of the switch rod 122 without being pushed back. When the slider 22 is moved backward in the slider cavity 213, the slider 22 will resist the elastic force of the resilient member 23. The switch rod 122 of the folding arm 12 will be dropped after losing the supportability so as to cause the free rotatable folding arm 1201 to rotate about the rotating rod 121. In other words, the free rotatable folding arm 1201 is dropped and folded with the fixed folding arm 1202.
When two arm portions of the folding arm 12 are folded with each other, the top supporting arms 11 and the supporting legs 13 are also folded accordingly. The rotation of the folding arm 12 will drive the supporting legs 13 to move about the pivot shafts 130. In other words, the supporting legs 13 are configured to rotate with the folding movements of the folding arms 12, such that the top supporting arm 11 is driven to rotate around the folding assembly 110 to be folded.
Accordingly, when the pulling strap 24 is pulled to operate the operation switch 20, the folding arm 12 will lose the support of the operation switch 20. Then, when folding arm 12 is folded due to gravity, the supporting legs 13, the top supporting arms 11 and the container body 30 are also folded along with the folding movements of the folding arms 12. Therefore, the foldable container is folded up by one single pulling action.
As shown in
The foldable supporting frame 10′ comprises at least two folding arms 12′ and at least four supporting legs 13′. Preferably, the number of the folding arms 12′ and the number of the supporting legs 13′ are designed accordingly. Each of the folding arms 12′ is correspondingly supported by the two supporting legs 13′.
In addition, according to the embodiment, the supporting legs 13′ are pivotally connected to each other about the pivot shaft 130′ and are driven by the folding arms 12 to rotate about the pivot shaft 130′. As shown in
According to the second embodiment, two of the operation switches 20 are installed on one of the folding arms 12′. The operation switch 20 has the same structure and function as the above-mentioned first embodiment, and thus not be repeated here. However, the switch rod 122′ is designed and shaped differently. The switch rod 122′ is integrally formed on the folding arm 12′ for providing supporting purpose.
In addition,
The foldable supporting frame 10′ is opened from the folded mode. The supporting legs 13′ are driven by the folding arms 12′ and are expanded about the pivot shafts 130′. The supporting legs 13′ can drive the folding arms 12′ to be opened. When the folding arms 12′ are unfolded to lay flat with each other, the folding arms 12′ are rotated about the rotating rod 121′. The folding arm 12′ will be supported by the operation switch 20 to restrict further downward movement, and further upward movement is restricted by the supporting leg 13′ and the pivot shaft 130′.
Specifically, when one of the folding arms 12′ is rotated toward another folding arm 12, the switch rod 122′ is lifted to the supporting end 211 of the slider 22. Each of the sliders 22 is configured to support the side of the switch rod 122′, such that the switch rod 122′ is symmetrically supported by the two operation switches 20. Then, each of the sliders 22 is pushed by the switch rod 122′ to move into the slider cavity 213, such that the switch rod 122′ will continue to lift and pass the slider 22. Each of the sliders 22 is pushed out of the slider cavity 213 by the resilient member 23 so as to protrude out of the slider cavity 213 again. The switch rod 122′ is supported by the slider 22 and placed on the two operation switches 20 when the slider 22 is protruded out of the slider cavity 213. Under the circumstance, the switch rod 112′ cannot push the slider 22 backward, and the weight of the switch rod 122′ is supported on the slider 22. Then, the folding arm 12′ is unfolded and is stably supported by the operation switch 20. The foldable supporting frame 10′ is then moved at the unfolded mode. The container body 30′ can be placed on the folding arms 12′.
Accordingly, as the folding arm 12′ or the supporting leg 13′ of the foldable supporting frame 10′ is unfolded, the folding arm 12′ is stably supported by the operation switch 20, such that the switch lever 122′ can support the weight of the container body 30′.
In addition, relationship and movement of the foldable container during the folding process according to the preferred embodiment are shown in
When the folding arm 12′ is unfolded, the switch rod 122′ is supported on the planar surface of the supporting end 221 to support the weight of the switch rod 122′ without being pushed back. In order to fold the foldable container, it is necessary to pull the two pulling straps 24′, such that each slider 22 is moved backward in the slider cavity 213. Each of the sliders 22 is pulled back in the slider cavity 213 against the elastic force of the resilient member 23. The switch rod 122′ of the folding arm 12′ will lose the support, and then will fall and rotate about the rotating rod 121′. In other words, one of the folding arms 12′ is dropped for being folded with another folding arm 12′. The rotation of the folding arm 12′ will drive the supporting leg 13′ to move about the pivot shaft 130′. In other words, as the folding arm 12′ is folded, the supporting leg 13′ is rotated correspondingly.
Normally, when the pulling strap 24 is pulled to actuate the operation switch 20, the folding arm 12′ will lose the support provided by the operation switch 20. Then the folding arm 12′ is folded by its own gravity, wherein the supporting leg 13′ is folded as the folding arm 12′ is folded. Therefore, the foldable container is folded by the single pulling action.
In an alternative mode of the present invention, two pulling straps 24 can be connected end-to-end. Then, by pulling only one of the pulling straps 24, the two operation switches 20 can be operated. In addition, the two ends of the pulling strap 24 are securely fastened to the two sliders 22 respectively. By pulling the pulling strap 24, the two operation switches 20 are operated at the same time.
Moreover, as shown in
In other words, at least two folding arms 12 and at least four supporting legs 13 are correspondingly configured, wherein each of the folding arms 12 is correspondingly supported by two supporting legs 13. Similarly, the supporting legs 13 are pivotally connected to each other about the pivot shaft 130, wherein the supporting leg 13 is driven by the folding arm 12 to rotate about the pivot shaft 130. As the folding arms 12 rotate about the rotating rod 121 to fold or unfold, the angle and distance between the folding arms 12 change. The supporting leg 13 is also driven to rotate about the pivot shaft 130. The operation switch 20 is coupled at one of the folding arms 12. The operation switch 20 has the same structure and function as the above mentioned first embodiment, and thus not being repeated here.
It is worth mentioning that the extension legs 14A of the foldable supporting frame 10 are implemented differently in the third embodiment. The extension leg 14A further comprises a rocking frame 141A, two corner frames 142A, and two foot stands 143A, wherein the rocking frame 141A is an elongated bar shape and is formed in a curved manner, wherein two ends of the rocking frame 141A is coupled to the two corner frames 142A respectively, wherein the foot stands 143A are pivotally coupled at the corner frames 142A respectively. The rocking frame 141A is arranged extended along a lower part of the supporting leg 13 in a convex manner for supporting on the ground. Each of the foot stands 143A comprises a supporting stand 1431A and a swinging stand 1432A integrally extended therefrom. For retaining the extension leg 14A at a stationary position, the supporting stands 1431A are rotatably extended toward a direction of the supporting leg 13 away from the rocking frame 141A and are rotatably folded away from each other to stand on the ground. For retaining the extension leg 14A at a rocking position, the supporting stands 1431A are rotatably folded to overlap with the rocking frame 141A, wherein the swinging stands 1432A are outwardly extended from the two corner frames 142A for limiting a rocking motion of the rocking frame 141A.
Furthermore, the supporting stand 1431A and the swinging stand 1432A are integrally formed in a one-piece member and are rotatably coupled at the corner frames 142A respectively. As shown in

Specifically, the container body 30 is connected with the operation switch 20, wherein the operation switch 20 is actuated to fold the foldable supporting frame 10. In other words, the operation of the container body 30 is configured to drive the operation of the operation switch 20, thereby realizing the folding operation of the foldable supporting frame from the container body 30. Since the container body 30 is folded by the pulling action to fold up the foldable supporting frame 10 at the same time, the entire folding operation of the foldable container is automatically actuated and completed by one pulling action.

Similarly, the foldable supporting frame 10B comprises at least two folding arms 12B and at least four supporting legs 13B that are correspondingly configured and connected, wherein each of the folding arms 12B is correspondingly supported by two supporting legs 13B. Similarly, the supporting legs 13B are pivotally connected to each other about pivot arms 131B, wherein the supporting leg 13B is driven by the folding arm 12B to rotate about the pivot arm 131B. As the folding arms 12B rotate about the rotating rod 121B to fold or unfold, the angle and distance between the folding arms 12B change. The supporting leg 13B is also driven to rotate about the pivot arm 131B. The operation switch 20B is coupled at one of the folding arms 12B. The operation switch 20B has the same structure and function as the above mentioned first embodiment, and thus not being repeated here.
