Description

Flowing enclosure

Technical Field

The invention relates to a household fence, in particular to a mobile fence which is convenient to transfer and is beneficial to storage.

Background

In modern home life, areas are divided according to functions, and specific things which can be done in specific areas are limited. However, there are many designs that are not child-friendly or where the parent's life conflicts with the child's play without complete preparation. In some cases, the pet cannot be domesticated to completely meet the condition of the living subareas of the house for activities. An accident will always occur.

In many cases, a fence (playpen) is provided in a house to enclose a specific place. For example, a fence type rail is arranged at the stair opening, so that children are prevented from falling down the stairs carelessly. The enclosure defines an area on the floor where a child can move about. There are also some existing fences, which enclose a small area in a living room or a yard, within which a pet can play, avoiding affecting the activities of other parents and children, and also being lost.

Although these prior art pens can draw certain areas to help better distinguish between different functional areas, they also suffer from a number of disadvantages. Firstly, many metal fences are permanent, can damage the original house structure, and cannot restore the wall state once not needed. However, some plastic fences have low stability and low interception performance, and the intercepted range is easily damaged. These plastic fences are also not easy to store and require a large storage space. Moreover, cleaning is cumbersome and difficult to regularly disinfect and maintain. In addition, some portable fences, which are made of metal wires and run through the fabric, can be opened like a tent, as shown in fig. 1. Although these portable fences can be deployed and used at any place, they are difficult to be quickly retracted due to their large tension, and therefore, the storage space is large. Moreover, these pens have cloth art, but these cloth art are difficult to remove for cleaning. Some of which cannot even be removed, require immersion or sterilization along with the wire. Then, the metal that plays a supporting role will be corroded, the supporting force and the elastic force will be greatly reduced over time, the safety of the whole fence will be reduced, and the service life will be shortened.

Of course, these pens need not only be portable in order to be stably placed in the desired location for use by children or pets. But also requires regular storage and cleaning to be maintained when not in use, rather than being a disposable item.

However, the storage ability and stability are two contradictory aspects, and the enclosure which is easy to store is also in danger of collapsing when being unfolded, and the enclosure which is stably supported is troublesome to store. Some parents give up using again because of laziness in storage and cleaning. A safe enclosure that is easy to store and maintain is desired by the market.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

The invention provides a flowing enclosure which is suitable for being used for separating a certain area in a specific place in the household life so that children or pets can be isolated in the area to carry out relatively safe activities. In particular, the flow barrier has an unfolded state and a folded state. When the mobile enclosure is in the unfolding state, a certain area is marked out by the mobile enclosure, so that parents can master the position and the state of the isolated children or pets. When in the folded state, the flow barrier is deformed into a compact configuration for transport and storage by transfer.

As shown in fig. 2A to 9, the flow barrier includes at least one stand arm 10, a plurality of support legs 20, and a surrounding body 30, wherein the stand arm 10 is foldably connected to the support leg 20 such that the support leg 20 changes following the state of the stand arm 10, and wherein the surrounding body 30 is detachably connected to the stand arm 10 and the support leg 20 such that the surrounding body 30 partitions a certain area when the stand arm 10 and the support leg 20 are unfolded.

More, the stand arm 10 and the support leg 20 are provided in linkage. That is, the support leg 20 is guided by the motion of the stand arm 10, or the stand arm 10 is guided by the motion of the support leg 20. In the preferred embodiment, the state of the support leg 20 is driven by the stand arm 10, that is, the stand arm 10 is in the dominant position.

When the stand arm 10 and the support leg 20 are opened with respect to each other, a certain range is defined by the stand arm 10 and the support leg 20 being supported with respect to each other. Furthermore, when the stand arm 10 and the support leg 20 are opened with respect to each other, the enclosure body 30 is supported accordingly. When the support arm 10 and the support leg 20 are folded against each other, the support arm 10 and the support leg 20 are folded against each other and placed so that the overall flow enclosure is in a folded state.

It is worth mentioning that the enclosure body 30 is adapted to be attached to the stand arm 10 and the support leg 20 or detached from the stand arm 10 and the support leg 20 in the unfolded state of the flow enclosure. Thus, the bulkhead 30 may preferably be attached or detached after use of the flow barrier from the unfolded state to the folded state. Of course, the enclosure body 30 can be unfolded or folded along with the support arm 10 and the support leg 20 of the flow enclosure, so that the flow enclosure can be quickly used for switching different scenes. That is, in the case where it is necessary to remove or attach the enclosure body 30 to the stand arm 10 and the support leg 20, it is preferable that the stand arm 10 and the support leg 20 are in the unfolded state. Of course, the enclosure body 30 can be attached or detached when the support arm 10 and the support leg 20 are folded.

Specifically, the enclosure 30 includes a plurality of walls 31 and a bottom pad 32, wherein the bottom pad 32 is integrally connected to edges of the walls 31, so that when the enclosure 30 is unfolded, the walls 31 and the bottom pad 32 are in the form of a frame. Preferably, the wall 31 is detachably mounted to the stand arm 10 and the supporting leg 20, respectively, so that the base pad 32 is brought to change. In another preferred embodiment, the base pad 32 is detachably coupled to the lower portion of the supporting leg 20, and each of the walls 31 is detachably coupled to the end of the supporting leg 20.

In the preferred embodiment, the wall 31 and the bottom pad 32 are detachably connected to the stand arm 10 and the support leg 20 in the form of a soft frame. Specifically, the wall 31 further includes a covered edge 311 at the upper edge of the wall 31. The edge 311 of the wall 31 is connected around the support arm 10 in a surrounding manner, so that the entire wall 31 is erected on the support arm 10. More specifically, the edge cover 311 is turned from the inside to the outside of the bracket arm 10, and is engaged with the bracket arm 10 after being turned over so that the wall 31 is mounted on the bracket arm 10.

On the one hand, after the wall 31 is connected to the stand arm 10 and the support leg 20, the stand arm 10 and the support leg 20 are isolated from the outside of the wall 31. In use, a child or pet located inside the enclosure 30 cannot directly contact the support arm 10 and the support leg 20. On the other hand, the wall 31 hides the state change switch of the stand arm 10 and the support leg 20. That is, the state change is not easily triggered in a general use, so that the states of the stand arm 10 and the supporting leg 20 are stabilized. The phase change is required, and the states of the support arm 10 and the support leg 20 are required to be changed under special and deliberate conditions. This provides an advantageous aspect of stability of the flow barrier in use and also provides for securing of the flow barrier in storage without the need for additional lashing.

In particular, the state transition of the support arms 10 and the support legs 20 of the flow barrier is as shown in fig. 3 to 8.

The holder arm 10 includes at least two arm bodies 11 and a lock switch 12 interposed between the arm bodies 11, wherein the lock switch 12 is operatively fixed to the arm bodies in such a manner that the arm bodies 11 are driven to transit states when the lock switch 12 is operated. In the preferred embodiment, the arm 11 is a rod-type structure with two mutually coupled parts and controlled by the locking switch 12. When the two arms 11 are relatively pivoted to be parallel or quasi-parallel, the arms 11 of the holder arm 10 are unfolded. When the arm bodies 11 are relatively pivoted to overlap, the arm bodies 11 of the holder arms 10 are retracted.

In the present preferred embodiment, when the lock switch 12 is operated, the two arm bodies 11 are fixed from the folded state to the unfolded state. That is, when the arm body 11 needs to be brought from the folded state to the unfolded state, the lock switch 12 is operated to fix the arm body 11 in the unfolded state. It is worth mentioning that the arm 11 is unfolded and the support leg 20 is unfolded accordingly. When the arm 11 is fixed in the unfolded state by the locking switch 12, the support leg 20 is also driven to the unfolded state, so that the enclosure body 30 of the flow enclosure is opened. When the arm body 11 is fixed in the unfolded state by the locking switch 12, the supporting leg 20 cannot be retracted, and the states of the stand arm 10 and the supporting leg 20 are fixed. That is, the state of the flow fence is stable without releasing the operation of the lock switch 12 to the arm 11, and the form is not changed by the collision.

Further, if the support legs 20 are unfolded and locked, not only the arm body 11 but also the support legs 20 cannot be folded toward the arm body 11 without operating the lock switch 12. When the arm 11 is unlocked by the lock switch 12, the support leg 20 can be rotated and folded.

More, the supporting leg 20 includes a plurality of leg bodies 21 and a locking mechanism 22 corresponding to the leg bodies 21, wherein the leg bodies 21 are rotatably connected to the arm body 11, wherein the locking mechanism 22 is movably fixed between the arm body 11 and the leg bodies 21. It is worth mentioning that the catch mechanism 22 is connected to the lock switch 12 and is influenced by the operation of the lock switch 12. The latch mechanism 22 is operated to move, thereby restricting the steering condition of the leg body 21. Preferably, the capture mechanism 22 is blocked in a way that it moves by restricting the turning line of the leg body 21. Then, when the locking mechanism 22 is operated to release the blocking, the leg body 21 can be rotated to be folded toward the arm body 11.

In the preferred embodiment, the leg body 21 is configured to be connected to the arm body 11 in a one-way direction. The locking mechanism 22 is telescopically restricted from the arm 11 in the turning direction of the leg 21. For example, when the locking mechanism 22 is extended to block the direction of the leg body 21, the leg body 21 cannot rotate.

It is worth mentioning that a change of state of the support arm 10 of the flow fence results in a change of state of the support leg 20. In the preferred embodiment, the operation of the stand arm 10 is relatively active and the support leg 20 acts passively following the stand arm 10. That is, the locking switch 12 of the stand arm 10 and the locking mechanism 22 of the support leg 20 are a combination of two linkages. The locking switch 12 of the stand arm 10 and the locking mechanism 22 of the support leg 20 are operated, and the other is driven to operate. Then, the folding operation of the stand arm 10 may cause the supporting leg 20 to be folded, whereas the folding operation of the supporting leg 20 may not cause the stand arm 10 to be folded. Thus, in use, the action on the support legs 20 does not collapse the entire flow enclosure, ensuring stability of the deployed state in use. Moreover, the unfolding operation of the stand arm 10 can simultaneously limit the unfolding of the support leg 20, and the stand arm 10 and the support leg 20 can be unfolded only by one operation.

In other embodiments, folding of the support legs 20 may also drive folding of the stand arms 10, but folding of the stand arms 10 does not affect folding of the support legs 20.

That is, the flow barrier has two switches that are linked to each other, one of which is operated relatively actively, and which brings about a relatively passive folding and unfolding action. Therefore, the flow barrier can be deployed or stowed in a single action, and in the deployed state, it cannot be easily released, but needs to be unlocked in a targeted manner. The unlocking of the flow barrier can be accomplished in a single action mode, requiring complex unlocking steps.

Furthermore, in the preferred embodiment, the arm 11 of the support arm 10 of the flow fence comprises a deployment rod 112 and a shaft end 111 connected to the other arm 11. In the preferred embodiment, there are two arm bodies 11, wherein the shaft end 111 of each arm body 11 is connected to each other in a unidirectional rotatable manner. That is, each of the shaft ends 111 provides two rotation shafts, and the unfolding rods 112 of the two arms 11 are opposite to the shaft ends 111, so that the two arms 11 are unfolded or folded oppositely. More specifically, the unfolding rod 112 has a frame portion 1121 and two corner portions 1122, wherein the corner portions 1122 extend from the frame portion 1121 in a meandering manner, so that the frame portion 1121 has a half-square shape. Then, the two deployment rods 112 are rotated with respect to the respective shaft ends 111 to assume a square-to-semi-square shape transition. The shaft end 111 is preferably disposed at the end of the deployment rod 112.

The lock switch 12 is operatively secured to each of the shaft ends 111 of the two arms 11 so as to limit the rotational direction of the deployment lever 112 relative to the shaft ends 111. In the deployed state, the relative rotation of the two deployment levers 112 is blocked by the locking switch 12. Preferably, the locking switch 12 secures the deployment lever 112 in a downwardly snapping manner in its relatively deployed state, as shown in fig. 3 and 4.

More specifically, the locking switch 12 further includes a rotating portion 121 and a limiting portion 122, wherein the limiting portion 122 is extended from the rotating portion 121, wherein the rotating portion 121 is movably fixed to one side of one of the shaft ends 111 of the unfolding rod 112, wherein the limiting portion 122 is integrally extended from the rotating portion 121 and is formed in a shape capable of peripherally wrapping the shaft end 111. When the rotating portion 121 is operated to move, the limiting portion 122 moves between contacting the shaft end 111 and moving away from the shaft end 111, so that the shaft end 111 is fixed or released by the limiting portion 122. It should be noted that the shaft ends 111 of the two deployment rods 112 in the preferred embodiment are pivotally connected to each other, and when the position-limiting portion 122 is driven to contact the shaft ends 111 of the two deployment rods 112, the ends of the two deployment rods 112 are fastened by the position-limiting portion 122, and the shaft ends 111 cannot rotate. That is, the pivotable positions of the two deployment levers 112 are fastened to be restricted so that the relative positions of the deployment levers 112 are fixed.

In the preferred embodiment, the deployment rod 112 is actuated in a flip-up fashion. That is, when the shaft ends 111 of the arm bodies 11 of the two holder arms 10 are rotated to be butted against each other, the stopper portion 122 of the lock switch 12 can be tightly bound to the peripheries of the two arm bodies 11, so that the two arm bodies 11 cannot be rotated with each other. When the limiting portion 122 of the lock switch 12 is away from the arm 11, and the shaft ends 111 of the two arms 11 are not limited, the two arms 11 can be folded by rotating around the shaft ends 111.

When the rotating portion 121 of the lock switch 12 is operated, the deployment levers 112 of the two arm bodies 11 are fixed from the folded state to the deployed state. That is, when the deployment lever 112 of the arm 11 needs to be moved from the folded state to the deployed state, the rotation portion 121 of the lock switch 12 is operated and the stopper portion 122 fixes the arm 11, so that the shaft end 111 is fixed when the deployment lever 112 is in the deployed state. It is worth mentioning that the unfolding rod 112 of the arm 11 is unfolded, and the leg 21 of the supporting leg 20 is unfolded and fixed by the locking mechanism 22. When the unfolding rod 112 of the arm 11 is fixed in the unfolded state by the position-limiting part 122 of the locking switch 12, the leg 21 of the supporting leg 20 is also driven to the unfolded state by the locking mechanism 22, so that the enclosing wall 30 of the flow enclosure is opened by the arm 11 and the leg 21. When the arm body 11 is fixed in the unfolded state by the stopper portion 122 of the lock switch 12, the leg body 21 of the supporting leg 20 cannot be retracted, and thus the states of the stand arm 10 and the supporting leg 20 are fixed. That is, the state of the flow fence is stable without releasing the operation of the stopper portion 122 of the lock switch 12 of the arm 11, and the form is not changed by the collision.

Further, when the locking mechanism 22 of the support leg 20 is unfolded and locked, the arm body 11 cannot be folded and folded not only by rotating the shaft end 111 but also by rotating the leg body 21 of the support leg 20 toward the arm body 11 without operating the stopper portion 122 of the lock switch 12. If the arm 11 is unlocked by the position-limiting portion 122 of the locking switch 12, the locking mechanism 22 of the support leg 20 is unlocked, and the leg 21 can be rotated and folded in the direction of the unfolding rod 112, so that the flow barrier is folded.

The leg body 21 is rotatably connected to the corner 1122 of the deployment lever 122. When the leg body 21 is rotated and folded, the leg body 21 overlaps the frame portion 1121 of the unfolding lever 122. When the leg body 21 is rotated and folded, the leg body 21 is supported perpendicularly to the frame portion 1121 of the deployment lever 122.

More specifically, the locking mechanism 22 of the support leg 20 further includes at least one connecting line 221 and the stop portion 222 corresponding to the leg body 21. The stopper 222 is connected to the connecting line 221 and movably connected to the joint position of the leg 21 and the corner 1122 of the deployment rod 112. The link 211 is driven by the lock switch 12 of the holder arm 10. More specifically, the connection wire 211 is connected to the rotating portion 121 of the lock switch 12, and the connection wire 211 drags the stopper portion 222 in accordance with the movement of the rotating portion 121. That is, the rotation portion 121 not only drives the stopper portion 122, but also indirectly drives the stop portion 222 via the connection line 211.

Further, the stopper 222 is provided at a position where the leg 21 and the deployment lever 112 meet each other. The stopper 222 is provided in the direction in which the leg body 21 rotates, extending from the deployment lever 112. The two ends of the leg body 21 are respectively an axial end 211 and a foot end 212. In the preferred embodiment, the stop portion 222 is connected to the outer side of the shaft end 211.

That is, when the stop portion 222 is driven to block the rotation of the shaft end 211 of the leg body 21, the leg body 21 is restricted from rotating and is relatively kept unfolded in the vertical direction, so that the leg body 21 is kept in the open state. More specifically, the rotation between the shaft end 211 of the leg body 21 and the corner 1122 of the deployment rod 112 is a fixed angle, for example, in the preferred embodiment, the rotation can be only performed between the parallel direction and the vertical direction of the deployment rod 122, and there is a rotation space of about 90 °. The rotation of the leg body 21 is also restricted by the stopper 222, and further rotation is not allowed. When the stop portion 222 is brought away from the limit of the leg body 21, the shaft end 211 of the leg body 21 can freely rotate and fold toward the unfolding rod 112.

In the preferred embodiment, the stop portion 222 is connected to the connecting line 221. In a case where the rotating portion 121 of the lock switch 12 of the holder arm 10 is operated to be unlocked, the stopper portion 222 is pulled upward so that the shaft end 211 of the leg body 21 has a space and an angle of rotation. When the rotating portion 121 of the lock switch 12 of the holder arm 10 is operated to be locked, the stopper portion 222 is slid downward, so that the space and angle of rotation of the shaft end 211 of the leg body 21 are prevented.

That is, the locking switch 12 of the stand arm 10 fixes the mutual positions of the arm bodies 11 in a snap-fit manner, and the locking mechanism 22 of the support leg 20 fixes the rotation restriction of the leg body 21 in a blocking manner. Also, the locking switch 12 and the capture mechanism 22 are interrelated. Operation of the lock switch 12 actuates the capture mechanism 22 such that locking or unlocking of the capture mechanism 22 is relatively passive.

More, the locking mechanism 22 further comprises an elastic portion 223, wherein the elastic portion 223 is disposed between the corner portion 1122 of the unfolding rod 112 and the stop portion 222, so that the stop portion 222 is driven by the elastic force to block the leg 21 without the traction of the connecting line 221 by the stop portion 222. That is, the stopper portion 222 has a tendency to move downward.

More specifically, in the unfolding state, the stop portion 222 is sleeved on the shaft end 211 of the leg body 21, so that the shaft end 211 cannot rotate relative to the unfolding rod 112, and the leg body 21 is kept unfolded. When the lock switch 12 does not drive the connection line 221 and the stopper 222 is pulled back, the leg body 21 cannot be folded relative to the stopper 222.

In the preferred embodiment, the flow barrier is a combination of buckling and sliding. In other preferred embodiments, the locking switch 12 and the capture mechanism 22 may be combined in any manner of locking and unlocking.

The application of the flow barrier from the unfolded state to the folded state is illustrated in fig. 3 and 5.

First, the lock switch 12 of the holder arm 10 is unlocked. That is, the stopper portion 122 of the lock switch 12 is operated to be away from the deployment lever 112. The deployment rods 112 can then be folded over one another along the shaft ends 111. Meanwhile, the action of the limiting part 112 causes the locking mechanism 22 of the supporting leg 20 to be triggered to unlock. That is, the connection line 211 of the locking mechanism 22 of the supporting leg 20 pulls the stop portion 222 upward, and the shaft end 211 of the leg body 21 is released from the limit by the stop portion 222. It should be noted that the limiting portions 112 are respectively connected to the two locking mechanisms 22, so that the operation of the two limiting portions 112 triggers the unlocking of the four support legs 20. Therefore, the leg body 21 of the support leg 20 can be folded, and the arm body 11 of the stand arm 10 is also folded relatively.

More, as shown in fig. 9, the support arm 10 and the support leg 20 are in a folded state, and the flow enclosure can be stored for convenient transportation and storage. Of course, after the edge covering 311 of the enclosure 30 is removed, the enclosure 30 may be further cleaned or sterilized.

The application of the flow barrier from the folded state to the unfolded state is shown in fig. 4 and 6.

First, the locking switch 12 of the stand arm 10 locks the deployment lever 112 in the open position. That is, the stopper portion 122 of the lock switch 12 is operated to clasp the deployment lever 112. The deployment rods 112 cannot then be folded onto each other along the shaft ends 111. Meanwhile, the action of the limiting part 112 causes the locking mechanism 22 of the supporting leg 20 to be triggered and locked. That is, the elastic portion 223 of the locking mechanism 22 of the support leg 20 elastically pushes down the stop portion 222, so that the shaft end 211 of the leg body 21 is restricted by the stop portion 222, and the leg body 21 cannot rotate. It should be noted that the two position-limiting portions 112 are respectively connected to the two position-locking mechanisms 22, so that the operation of the two position-limiting portions 112 triggers the locking of the four support legs 20. Therefore, the leg body 21 of the support leg 20 is unfolded and supported, and the arm body 11 of the stand arm 10 is also unfolded relatively, thereby forming a movement space.

Further, as shown in fig. 16, the support arms 10 and support legs 20 are in an unfolded state and the flow fence can be placed in a specific location for use by a child. Of course, the wall 31 of the enclosing body 30 is further provided with a door 312 for children to play. By means of the door 312 of the wall 31, the activity space can be enlarged, for example by connecting the door 312 to more play space.

A flow fence according to another preferred embodiment of the present invention is illustrated, as shown in fig. 10 to 15, wherein the flow fence comprises a support arm 10A, a support leg 20A and a fence body 30A, wherein the support leg 20A and the fence body 30A have similar structures to the support leg 20 and the fence body 30 of the flow fence according to the first preferred embodiment, and the description of the present invention is omitted.

In the preferred embodiment, the holder arm 10A of the flow barrier is different from the above-mentioned embodiment, and the locking switch 12A includes a limiting portion 121A and a rotating portion 122A, wherein the shaft end 111A of the arm body 11A is rotatably disposed on the limiting portion 121A, and wherein the rotating portion 122A is rotatably disposed on the side end of the shaft end 111A of the arm body 11A. Preferably, the rotating portion 122A is block-shaped.

More specifically, the stopper portion 121A is formed in a pipe shape having a top surface and an inner cavity. As shown in fig. 11 and 12, the shaft ends 111A of the two arm bodies 11A are pivotally fixed to both ends of the stopper portion 121A, respectively, so as to be rotatable within an angular range of approximately 90 ° under the surrounding of the stopper portion 121A. When the shaft ends 111A of the two arm bodies 11A rotate and are straight with each other, the shaft ends 111A of the arm bodies 11A are blocked by the stopper portion 121A to continue the upward rotation.

In the present preferred embodiment, the rotating portion 122A is disposed in the middle of the stopper portion 121A so as to be simultaneously disposed between the end side portions of the shaft ends 111A of the two arm bodies 11A. The rotating portion 122A is disposed in the inner cavity of the limiting portion 121A in a blocking manner, and can be rotated to leave the inner cavity of the limiting portion 121A. When the rotating portion 122A is disposed on the limiting portion 121A, the sides of the shaft ends 111A of the two arm bodies 11A are blocked by the rotating portion 122A, and the tops of the shaft ends 111A of the arm bodies 11A are blocked by the limiting portion 121A. Therefore, the shaft ends 111A of the arm bodies 11A cannot rotate freely and are fixed in a mutually straight position, so that the holder arms 10A are unfolded. When the rotating portion 122A is rotated away from the stopper portion 121A, the end side of the shaft end 111A of the arm body 11A is not abutted by the rotating portion 122A, so that the gravity influence of the deployment lever 112A of the arm body 11A can rotate downward. When the rotating portion 122A no longer restricts the arm body 11A, the arm bodies 11A can be rotated mutually to be folded.

It should be noted that when the rotating portion 122A is inserted into the limiting portion 121A and located between the two shaft ends 111A, the rotating portion 122A receives the pressing force from the arm 11A, and the position cannot be easily changed, so as to ensure that the unfolding state of the arm 11A is not easily changed. In other words, the deployed state of the arm body 11A is changed only by intentionally pulling out the rotating portion 122A from the stopper portion 121A. Preferably, the rotatable angle range of the rotating portion 122A is toward the outside, so that the operation of the internal environment of the enclosure body 30 does not easily interfere with the rotating portion 122A.

Preferably, the rotating portion 122A is resiliently connected to the stopper portion 121A. When the rotating portion 122A is pulled away from the stopper portion 121A, the rotating portion 122A can automatically rotate toward the stopper portion 121A and be reset to the stopper portion 121A.

More preferably, the line 221A of the locking mechanism 22A of the support leg 20A is connected to the turning portion 122A. When the rotating portion 122A is pulled, the connecting line 221A is triggered to drive the stopping portion 222A to release the limitation of the leg 21A. That is, from the unfolded state to the folded state, the rotating portion 122A needs to be pulled, and the arm body 11A and the leg body 21A are respectively released from the position restriction and further folded. Also, it is preferable that the operation of the rotation part 122A has a certain countermeasure, and the rotation part 122A cannot be easily separated from the stopper part 121A by an unintended operation.

As shown in fig. 14, in the deployed state, the shaft end 111A of the arm 11A is restricted by the stopper portion 121A from turning upward and restricted by the rotating portion 122A from turning downward. The leg body 21A is restricted by the locking mechanism 22A and is not rotatable. When the user needs to fold the flow barrier, pulling the rotating portion 122A will not restrict the shaft end 111A of the arm 11A and rotate it downward, but will pull the connecting wire 221A and pull the stop portion 222A back to release the downward extension restriction of the shaft end 211A of the leg 21A. The leg body 21A and the arm body 11A are respectively rotatable and foldable. Preferably, the leg 21A is turned towards the arm 11A, while the two arms 11A are turned relative to each other, so that the whole flow barriers are stacked.

A flow fence according to another preferred embodiment of the present invention is illustrated, as shown in fig. 17 to 21E, wherein the flow fence includes a bracket arm 10B, a supporting leg 20B and a fence body 30B, wherein the structures of the supporting leg 20B and the fence body 30B are similar to the bracket arm 10A, the supporting leg 20A and the fence body 30A of the flow fence according to the second preferred embodiment, and repeated description of the present invention is omitted below.

In the preferred embodiment, the support arm 10B of the flow barrier is different from the above-mentioned embodiments in that the arm body 11A in the second preferred embodiment is folded downward and unfolded upward in the vertical direction, and the arm body 11B in the present preferred embodiment is folded inward and unfolded outward in the horizontal direction. The lock switch 12B is basically the same in structure as the second embodiment.

Each of the deployment bars 112B of the arm 11B further includes a first deployment bar 1121B and two second deployment bars 1123B, wherein the first deployment bar 1121B and the two second deployment bars 1123B are connected by two of the corners 1122B to form a half-square of the deployment bar 112B. The second spreading bar 1123B has the shaft end 111B at one end and a pull end at the other end.

It is worth mentioning that the shaft end 111B of the second spreading lever 1123B and the locking switch 12B are similar in structure to those of the above-described embodiment. The stopper portion 121B is formed in a channel shape having a side surface and an inner cavity. As shown in fig. 18 and 19, the shaft ends 111B of the respective two second spreading levers 1123B are pivotally fixed to both ends of the stopper portion 121B, respectively, so as to be rotatable within an angle range approximately equal to 90 ° under the surrounding of the stopper portion 121B. When the shaft ends 111B of the two second spreading rods 1123B are rotated to be flat, the shaft ends 11B of the second spreading rods 1123B are blocked by the stopper 121B to continue to rotate outward.

In the preferred embodiment, the two arms 11B are pivoted inward or outward in the horizontal plane. The rotating portion 122B is disposed in the middle of the limiting portion 121B so as to be capable of being inserted between the ends of the shaft ends 111B of the two arm bodies 11B.

As shown in fig. 18, when the rotating portion 122B is rotated to be away from the limiting portion 121B, the outer end side of the shaft end 111B of the second unfolding rod 1123B of the arm body 11B is not resisted by the rotating portion 122B, and the support arm 10B is folded by pulling the locking switch 12B inward to rotate the second unfolding rod 1123B outward.

As shown in fig. 19, when the second spreading rod 1123B rotates inward, the side of the shaft end 111B of the second spreading rod 1123B of the two arm bodies 11B is blocked by the limiting portion 121B, so that the two second spreading rods 1123B are relatively straight. After the rotating portion 122B is lowered to the limiting portion 121B, the inner end of the shaft end 111B of the second spreading rod 1123B of the arm 11B is stopped by the rotating portion 122B. Therefore, the shaft ends 111B of the second deployment rod 1123B of the arm body 11B are fixed in a mutually straight position without freely rotating, so that the stent arm 10B is deployed.

Further, as shown in FIG. 20, the locking mechanism 22B of the support leg 20B further comprises a groove 224B formed at the top end 211B of the leg body 21B and a protrusion 222B formed at the pulling end of the second spreading bar 1123B. The projection 222B and the groove 224B are fittingly fittable to each other.

Specifically, the corner 1122B of the deployment rod 112B is a tube having a twitch port 11223B, a fixation port 11221B and a leg receiving port 11222B. The draw port 11223B of the corner portion 1122B movably receives the second deployment rod 1123B, the securing port 11221B of the corner portion 1122B fixedly connects to the first deployment rod 1121B, and the leg receiving port 11222B of the corner portion retractably connects to the top end 211B of the leg 21B. While the second spreading bar 1123B is rotated at the shaft end 111B, the pulling end of the second spreading bar 1123B moves within the pulling port 11223B of the corner 1122B within a certain range, so that the protrusion 222B formed at the pulling end of the second spreading bar 1123B also moves within the pulling port 11223B of the corner 1122B.

When the second spreading lever 1123B is spread, the projection 222B and the groove 224B of the top end 211B of the leg body 21B are engaged with each other in the corner 1122B, so that the leg body 21B is fixed in the leg body receiving opening 11222B at the corner in a mutually perpendicular connection with respect to the second spreading lever 1123B. When the second spreading bar 1123B is folded, the protrusion 222B of the drawing end is removed and the grooves 224B of the top end 211B of the leg 21B are separated from each other in the corner portion 1122B, so that the leg 21B is movably received in the leg receiving opening 11222B of the corner portion 1122B, and the leg 21B is separated from the spreading bar 112B and then automatically folded.

The process of the stand arm 10B and the support leg 20B of the present preferred embodiment from the folded state to the unfolded state is shown in fig. 21A to 21E. It should be noted that the enclosing wall 30B can always wrap the support arm 10B and the support leg 20B, and the process of deforming the enclosing wall 30B is partially omitted in the drawings. And, the enclosure body 30B provides a certain accommodating range of the stand arm 10B and the support leg 20B, so that the stand arm 10B and the support leg 20B are prevented from being scattered off the enclosure body 30B.

In the fully collapsed position, the second deployment rod 1123B is folded into a generally X-shaped, inwardly collapsed position. The rotating portion 122B is located outside the stopper portion 121B, and the leg body 21A is not connected to the deployment rod 112B and can be arbitrarily placed below the deployment rod 112B.

First, the groove 224B of the tip 211B of the leg body 21B is inserted into the leg body accommodating port 11222B of the corner. So that the leg body 21B is received in the leg body receiving opening 11222B of the corner portion, and is connected perpendicularly to the second spreading bar 1123B.

Then, moving the locking switch 12B outward, the second spreading lever 1123B will rotate inward. The shaft ends 111B of the second spreading rods 1123B of the two arm bodies 11B are laterally blocked by the limiting part 121B and do not excessively rotate. At this time, the projection 222B and the groove 224B of the top end 211B of the leg body 21B are engaged with each other in the corner 1122B, so that the leg body 21B is fixed to the leg body receiving opening 11222B of the corner.

Then, when the two second spreading bars 1123B are relatively straight. The rotating portion 122B can be put into the limiting portion 121B for being inserted between the inner ends of the shaft ends 111B of the second spreading rod 1123B of the arm body 11B. When the rotating part 122B is lowered to the position-limiting part 121B, the shaft ends 111B of the second spreading rods 1123B of the arm body 11B cannot rotate freely and are fixed at a mutually straight position, so that the support arm 10B is spread.

It is worth mentioning that, without releasing the relative position of the rotating portion 122B with respect to the stopper portion 121B, not only the second expanding lever 1123B is not rotated, but also the leg body 21B is continuously kept connected, so that the expanded state of the integrated bracket arm 10B and the support leg 20B is locked. Preferably, the rotatable angle range of the rotating portion 122B is toward the outside, so that the operation of the internal environment of the surrounding body 30B does not easily interfere with the stabilization of the rotating portion 122B. In other words, the flow barrier continues to remain deployed without intentionally snapping or snapping the turning portion 122B open.

The flowing enclosure is suitable for being separated into a certain area in a specific place in the household life in the unfolded state, so that children or pets can be separated in the area to carry out relatively safe activities. The area marked by the mobile enclosure is beneficial to parents to master the position and the state of the isolated children or pets. The flow enclosure has a small overall volume and thickness in a folded state for storage and storage, and is also conveniently carried to a desired location.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
