[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this invention; the terms "including" and "having" and any variations thereof in the specification and claims of this invention and the accompanying drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0063] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0064] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0065] See attached Figures 1 to 16 The utility model provides a telescopic door, which includes a base 1, a main rod 2, a flexible fence member 3, a rebound device 4, a mounting member 5 and a plurality of steering brackets 6.

[0066] The base 1 is designed to be mounted on the ground, wall, door frame, or other fixed object. A main pole 2 is vertically positioned and rotatably mounted on the base 1. A flexible fence member 3 includes a first end 31 and a second end 32. The flexible fence member 3 is retracted onto the main pole 2, with the first end 31 fixedly connected to the main pole 2 and the second end 32 being able to be pulled outward for extension. The flexible fence member 3 is made of fabric.

[0067] The rebound device 4 connects the base 1 and the main rod 2 and is used to provide elastic force along the circumference of the main rod 2. After the main rod 2 is driven by an external force to rotate in the forward direction, when the external force is removed, the rebound device 4 can cause the main rod 2 to rotate in the reverse direction and return to its original position.

[0068] The mounting member 5 is connected to the second end 32. External force pulls the mounting member 5, causing the second end 32 to move with the mounting member 5 until the mounting member 5 is fixed to a wall, door frame or other fixed object, and the position of the second end 32 is also fixed.

[0069] The steering bracket 6 can be fixed to the ground, a wall, or other fixed objects, and a plurality of steering brackets 6 can be placed against any side surface 33 of the flexible fence 3, so that the flexible fence 3 can be bent around any steering bracket 6. In other words, the steering bracket 6 is used to change the deployment direction of the flexible fence 3.

[0070] When using, if attached Figure 1As shown, the base 1 is fixed on the wall, the steering bracket 6 is installed on the ground, and the mounting member 5 and the second end 32 of the flexible fence member 3 are pulled to unfold the flexible fence member 3. During the unfolding process of the flexible fence member 3, the flexible fence member 3 is placed against each steering bracket 6 in turn, and is bent around each steering bracket 6 in turn, and finally the mounting member 5 is fixed to the wall, so that the flexible fence member 3 and the wall together enclose an isolation space with a polygonal structure. Among them, the different placement positions of the steering brackets 6 will affect the bending position of the flexible fence member 3, and the polygonal structure finally formed will also be different. Therefore, the telescopic door can be used to form an isolation space of complex shape.

[0071] As attached Figure 2 As shown, in one embodiment, there are only two steering brackets 6, and both steering brackets 6 abut against the same side surface 33 of the flexible fence member 3, so that the flexible fence member 3 forms a trapezoidal structure, with the first end 31 and the second end 32 together forming an opening 300. The base 1 and the mounting member 5 are both fixed to the wall, and the opening 300 is closed by the wall.

[0072] As attached Figure 3 As shown, in another embodiment, there are four steering brackets 6, which are respectively arranged on two side surfaces 33 of the flexible fence member 3, so that the flexible fence member 3 forms an irregular polygonal structure, and the first end 31 and the second end 32 together form an opening 300. The base 1 and the mounting member 5 are both fixed to the door frame, and the opening 300 is connected to the door frame.

[0073] Regarding the structure of the steering bracket 6, in a preferred embodiment, the steering bracket 6 includes a fixed platform 61 and at least one auxiliary rod 62. The fixed platform 61 is used to be installed on the ground, wall, or other fixed objects. The auxiliary rod 62 is plugged and fixed on the fixed platform 61 or fixed on the fixed platform 61 by screws. The auxiliary rod 62 is arranged parallel to the main rod 2. The auxiliary rod 62 can be rested on any side 33 of the flexible fence member 3, and the flexible fence member 3 can be bent around the auxiliary rod 62.

[0074] The fixing platform 61 may be supported on the ground by its own weight, or may be fixed to the ground by gluing, or may be fixed to the ground by bolts.

[0075] Furthermore, since the flexible fence member 3 is soft, in order to prevent objects or creatures from passing through the bottom of the flexible fence member 3, in a preferred embodiment, as shown in the attached Figure 1 and 6As shown, the telescopic door further includes a plurality of shaping rods 7, which are arranged parallel to the main rod 2 and pass through the flexible fence 3. The shaping rods 7 are distributed along the length of the flexible fence 3. A shaping rod 7 is passed through the flexible fence 3 at intervals to maintain the vertical shape of the flexible fence 3 and provide sufficient strength for the bottom edge of the flexible fence 3 to prevent objects or organisms from exerting pressure on the bottom of the flexible fence 3 and deforming it.

[0076] Furthermore, in order to lock the unfolded length of the flexible fence member 3 when in use and prevent it from naturally retracting due to the elastic force of the rebound device 4, in a preferred embodiment, as shown in the attached Figure 7 and 8 As shown, the base 1 includes an upper connecting head 11, a lower connecting head 12 and a connecting rod 13. The connecting rod 13 is fixedly connected to the upper connecting head 11 and the lower connecting head 12. The upper end of the main rod 2 is rotatably connected to the upper connecting head 11, and the lower end of the main rod 2 is rotatably connected to the lower connecting head 12. The rebound device 4 is installed in the main rod 2 and connected to the lower connecting head 12. Figure 15 shown.

[0077] The upper connector 11 comprises a housing 111, a rotating member 112, a snap-fit member 113, a first elastic member 114, and a rotary switch 115. The housing 111 is fixedly connected to the connecting rod 13. The rotating member 112 is rotatably connected within the housing 111 and connected to the main rod 2. The rotating member 112 rotates synchronously with the main rod 2. The rotating member 112 is provided with a first snap-fit structure 1121 disposed around its circumference. The snap-fit member 113 is rotatably connected within the housing 111 and can swing toward or away from the rotating member 112. The snap-fit member 113 is provided with a second snap-fit structure 1131, which can engage or disengage with the first snap-fit structure 1121. The two ends of the first elastic member 114 are respectively connected to the clamping member 113 and the shell 111. The first elastic member 114 is a compression spring. The first elastic member 114 is used to drive the clamping member 113 to swing toward the rotating member 112 so that the second clamping structure 1131 and the first clamping structure 1121 are clamped with each other.

[0078] As attached Figure 7 、 8As shown in Figures 9 and 10, the rotary switch 115 is exposed from the upper surface of the housing 111. The rotary switch 115 is rotatably mounted on the housing 111. The rotary switch 115 is provided with a switch boss 1151 located inside the housing 111. The switch boss 1151 can rotate along with the rotary switch 115, and the switch boss 1151 can abut against the clamping member 113. When it is necessary to lock the main rod 2 and prevent the main rod 2 from rotating, the switch boss 1151 does not abut against the clamping member 113. At this time, the clamping member 113 abuts against the rotating member 112 due to the elastic force of the first elastic member 114, so that the first clamping structure 1121 and the second clamping interface are mutually engaged, thereby preventing the rotating member 112 from rotating and stopping the rebound device 4 from working. When it is necessary to release the restriction on the rotation of the main rod 2, the user can twist the rotary switch 115, so that the switch boss 1151 presses and drives the clamping member 113 to swing away from the rotating member 112, so that the second clamping structure 1131 and the first clamping structure 1121 are separated from each other, and the rotation restriction on the rotating member 112 is released, and the rebound device 4 starts to work and retracts the flexible fence member 3.

[0079] The housing 111 is provided with a mechanism for locking the angle of the rotary switch 115, as shown in the attached diagram. Figure 8 As shown, in a preferred embodiment, a rotation groove 1113 is defined on the surface of the housing 111. The rotary switch 115 rotates within the rotation groove 1113. A compression spring is interposed between the rotary switch 115 and the housing 111, enabling a vertical sliding relationship between the rotary switch 115 and the housing 111. A limiting boss 1152 is provided at the bottom of the rotary switch 115. The rotation groove 1113 also defines a transversely extending through-hole 11131. A first notch 11132 and a second notch 11133 are respectively provided at each end of the through-hole 11131, extending vertically along the inner wall of the rotation groove 1113. The limiting boss 1152 is disposed through the through-hole 11131. When the rotary switch 115 locks the flexible fence member 3, the limiting protrusion 1152 is located within the first notch 11132. The user can press the rotary switch 115 to disengage the limiting protrusion 1152 from the first notch 11132. Rotating the rotary switch 115 then moves the limiting protrusion 1152 below the second notch 11133. When the external force on the rotary switch 115 is released, the limiting protrusion 1152, under the elastic force of the compression spring, moves upward into the second notch 11133, unlocking the flexible fence member 3. The limiting protrusion 1152 is primarily intended to prevent the rotary switch 115 from rotating on its own, requiring the user to manually unlock it.

[0080] Regarding the specific arrangement of the first clamping structure 1121 and the second clamping structure 1131, in a preferred embodiment, as shown in the attached Figure 13As shown, the first engaging structure 1121 includes a first ratchet gear 11211 and a second ratchet gear 11212, both arranged vertically around the circumference of the rotating member 112. The first ratchet gear 11211 and the second ratchet gear 11212 are arranged in opposite directions. The second engaging structure 1131 includes a first hook 11311 and a second hook 11312, both arranged vertically. The first hook 11311 can engage with the first ratchet teeth, and the second hook 11312 can engage with the second ratchet teeth. The engagement between the first ratchet gear 11211 and the first hook 11311 prevents the rotating member 112 from rotating counterclockwise, while the engagement between the second ratchet gear 11212 and the second hook 11312 prevents the rotating member 112 from rotating clockwise. Therefore, the simultaneous provision of the first ratchet gear 11211 and the second ratchet gear 11212 can prevent the rotating member 112 from rotating.

[0081] Regarding the connection structure between the rotating member 112 and the main rod 2, as shown in the attached Figure 14 As shown, specifically, the main rod 2 is hollow, a positioning boss 21 is provided inside the main rod 2, and a positioning groove 11221 is provided at the lower end 1122 of the rotating member 112. The lower end 1122 of the rotating member 112 can be inserted into the main rod 2, and the positioning boss 21 is placed in the positioning groove 11221. The positioning boss 21 and the positioning groove 11221 both extend in the vertical direction. The rotation of the main rod 2 causes the positioning boss 21 to abut against the main rod 2, thereby driving the rotating member 112 to rotate synchronously with the main rod 2.

[0082] In addition, as attached Figure 7 As shown, the upper connector 11 also includes a stopper 119, which is fixedly connected to the housing 111 by screws, and the stopper 119 is used to abut against the top of the rotating member 112 to prevent the rotating member 112 from separating from the main rod 2. A sliding column 1112 is provided in the housing 111, and the clamping member 113 is sleeved on the sliding column 1112. The edge radius of the stopper 119 is larger than the radius of the rotating member 112, and an anti-slip groove 1132 is provided on the clamping member 113. As the clamping member 113 approaches the rotating member 112, the edge of the stopper 119 can enter the anti-slip groove 1132, which can prevent the clamping member 113 from deviating in the up and down directions, that is, prevent the first clamping structure 1121 and the second clamping structure 1131 from being separated from each other up and down.

[0083] Furthermore, as attached Figure 7 and 12As shown, the upper connector 11 further includes a sliding buckle 116, a second elastic member 117, and an unlocking button 118. The sliding buckle 116 is slidably connected to the housing 111 and is provided with a latching platform 1161. The two ends of the second elastic member 117 are respectively connected to the sliding buckle 116 and the housing 111. The unlocking button 118 penetrates the housing 111 and is vertically slidably connected to the housing 111. The unlocking button 118 is provided with a first inclined platform 1181, and the sliding buckle 116 is provided with a second inclined platform 1162. The first inclined platform 1181 and the second inclined platform 1162 abut against each other. Pressing the unlocking platform causes the unlocking button 118 to slide upward, which drives the first inclined platform 1181 to rise. As the first inclined platform 1181 rises, the second inclined platform 1162 correspondingly translates, thereby causing the sliding buckle 116 to translate.

[0084] The telescopic door further includes a first fixing member 8, which is used to be mounted on a wall, door frame, or other fixed object. The first fixing member 8 is provided with a fixing hook 81, and the housing 111 is provided with a fixing hole 1111. The fixing hook 81 can pass through the fixing hole 1111 and extend into the housing 111. The fixing hook 81 is provided with a latch 811, and the latch platform 1161 can be placed in the latch 811 as the sliding latch 116 moves horizontally, so as to prevent the fixing hook 81 from being separated from the housing 111, thereby locking the housing 111 to the first fixing member 8.

[0085] Regarding the fixing structure of the mounting member 5, in a preferred embodiment, as shown in the attached Figure 16 As shown, the mounting member 5 is rod-shaped, and the telescopic door also includes a second fixing member 9. The mounting member 5 has a positioning lock plate 51. The second fixing member 9 can be attached to a wall, door frame, or other fixed object by gluing or screwing. The second fixing member 9 is provided with a vertically extending positioning lock slot 91. The positioning lock plate 51 can slide downward into the positioning lock slot 91, thereby achieving a detachable connection between the mounting member 5 and the second fixing member 9.

[0086] In addition, a manually unlockable locking mechanism can be provided on the second fixing member 9. When the positioning lock platform 51 enters the positioning lock groove 91, the locking mechanism is used to prevent the positioning lock platform 51 from being separated from the positioning lock groove 91. Figure 16 As shown, a sliding hook 92 and an unlocking slide 93 can be slidably disposed on the second fixing member 9. The sliding hook 92 can extend into the positioning lock slot 92, and the unlocking slide 93 is connected to the sliding hook 92. By moving the unlocking slide 93, the user can drive the sliding hook 92 into or out of the positioning lock slot 91 to lock or unlock the positioning lock stage 51. In other words, when the positioning lock stage attempts to move upward out of the positioning lock slot, the positioning lock stage will abut against the sliding hook, thereby preventing the positioning lock stage from further disengaging. In addition, the unlocking slide 93 can also be used in conjunction with a spring to help the unlocking slide 93 automatically reset.

[0087] When the fence needs to be opened, the user can manually slide the unlocking slide 93, and then disengage the positioning lock platform 51 from the positioning lock slot 91. The second end 32 of the flexible fence member 3 can change position along with the mounting member 5, thereby opening the isolation space.

[0088] The telescopic door may also include a third fixing member 1001 and a fourth fixing member 1002, both of which are used to securely mount to a wall, door frame, or other fixed object. A first mating member 1003 is slidably coupled to the connecting rod. As the first fixing member and the housing are mated, the first mating member also connects to the third fixing member. The third fixing member can have the same or similar structure as the first fixing member. A second mating member 1004 is slidably coupled to the mounting member. As the mounting member and the second fixing member are mated, the second mating member also connects to the fourth fixing member. The fourth fixing member can have the same or similar structure as the second fixing member.

[0089] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms.
