Description

Technical Field

[0001] This utility model relates to safety gates, and more particularly to a tensioned soft gate. Background Technology

[0002] Families with young children can install safety barriers at stairwells or doorways to prevent children from accidentally entering dangerous areas. Some existing flexible barriers include a base frame, a rotating assembly, a locking assembly, and a retractable elastic element. The rotating assembly consists of a rotating shaft and a flexible barrier body; the rotating shaft unfolds or retracts the flexible barrier body when rotated. In use, the base frame is installed on one wall. The user overcomes the force of the retractable elastic element to unfold the flexible barrier body and secures the protruding end of the flexible barrier body to the other wall, thus blocking the stairwell or doorway. At this point, the retractable elastic element initially tensions the flexible barrier body. Subsequently, the locking assembly secures the rotating shaft, preventing the rotating shaft from loosening and affecting the flexible barrier body. However, with these flexible barriers, the tension of the flexible barrier body is relatively low after the locking assembly secures the rotating shaft, and it may loosen and deform upon impact. Therefore, there is still room for improvement in its protective capabilities. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a tensioned flexible gate, which further tensions the flexible gate body during use, making it less prone to loosening and deformation, thus improving its protective capabilities.

[0004] A tensioned flexible door frame according to an embodiment of the present invention includes a base frame, a rotating assembly, a locking assembly, and a tensioning mechanism. The rotating assembly includes a rotating shaft and a flexible door frame. The rotating shaft is rotatably mounted on the base frame, and the flexible door frame is wound around the outside of the rotating shaft. One end of the flexible door frame is located on the rotating shaft, and the other end is an extended end. When the rotating shaft rotates clockwise, the flexible door frame unfolds; when the rotating shaft rotates counterclockwise, the flexible door frame retracts. The locking assembly is mounted on the base frame and can be switched between a locked state and an unlocked state. In the locked state, the locking assembly restricts the clockwise rotation of the rotating shaft and allows the rotating shaft to rotate counterclockwise. In the unlocked state, the rotating shaft can rotate clockwise and counterclockwise. The tensioning mechanism is mounted on the base frame. When the locking assembly is in the locked state, the tensioning mechanism can drive the rotating shaft to rotate counterclockwise. A retractable elastic element is mounted on the base frame and can apply a force to reverse the rotation of the rotating frame.

[0005] The tensioned flexible gate according to the present invention has at least the following beneficial effects: the base frame is installed on one side wall, and the user overcomes the force of the retractable elastic element to unfold the flexible gate to a certain length and fix the extended end of the flexible gate. At this time, the retractable elastic element initially tensions the flexible gate. Then, the locking component is switched from the unlocked state to the locked state. At this time, the locking component restricts the rotation axis from rotating forward, so that the flexible gate cannot continue to unfold. Subsequently, the tensioning mechanism drives the rotation axis to reverse a certain angle to further tension the flexible gate. The locking component keeps the rotation axis in the angle position after further tensioning, so that the flexible gate is not easy to loosen or deform, thus improving the protective capability.

[0006] According to some embodiments of the present invention, the locking assembly includes a transmission member and a locking member. The transmission member is movably disposed on the base frame along the rotation axis of the rotating shaft and has a downward state and an upward state. The transmission member is rotatably disposed on the base frame about the rotation axis of the rotating shaft. At least two ratchet teeth are arranged on the outer side of the transmission member. The locking member is provided with a pawl. The locking member is movably disposed on the base frame and can engage the pawl with the ratchet teeth to lock the locking assembly, and can also separate the pawl from the ratchet teeth to unlock the locking assembly. In the downward state, the transmission member is driven and rotates synchronously with the rotating shaft. In the upward state, the transmission member is separated from the rotating shaft.

[0007] According to some embodiments of the present invention, the locking assembly further includes a toggle switch and a first elastic member. The toggle switch is movably disposed on the base frame and can avoid the locking member or drive the locking member to separate from the transmission member. The first elastic member is disposed between the base frame and the locking member and is used to drive the locking member to abut against the transmission member.

[0008] According to some embodiments of the present invention, the locking assembly further includes a limiting member and a second elastic member. The limiting member is movably disposed on the base frame and can restrict or allow the transmission member to switch from the lowering state to the uppering state. The second elastic member is disposed between the base frame and the transmission member and is used to drive the transmission member to move from the lowering state to the uppering state.

[0009] According to some embodiments of the present invention, the limiting member is movably disposed on the base frame along the rotation axis of the rotating shaft and has a downward state and an upward state. The limiting member is stacked on the upper side of the transmission member. The limiting member is rotatably disposed on the base frame about the rotation axis of the rotating shaft and has a first angular position and a second angular position. The base frame is provided with a first stop block. In the upward state, the first stop block restricts the limiting member to the first angular position. In the downward state, the limiting member can rotate to switch between the first angular position and the second angular position. In the second angular position, the limiting member is located below the first stop block and restricts the upward movement of the limiting member.

[0010] According to some embodiments of the present invention, the toggle button is provided with a lever along the rotation axis of the rotating shaft, the lever is opposite to the locking member, the limiting member is provided with a mating hole, the lever passes through the mating hole, and the toggle button can drive the limiting member to swing.

[0011] According to some embodiments of the present invention, the locking assembly further includes a button and a third elastic member. The button is slidably disposed on the base frame along the rotation axis of the rotating shaft and has a downward state and an upward state. When the button moves downward, it can drive the limiting member and the transmission member to move downward. The third elastic member is disposed between the button and the limiting member and is used to drive the button to move upward. The button is provided with a second stop block. In the upward state, the second stop block restricts the limiting member from rotating from the second angle position to the first angle position. In the downward state, the second stop block avoids the limiting member.

[0012] According to some embodiments of the present invention, the locking assembly further includes a rotary reset member, which is disposed between the transmission member and the base frame and can drive the transmission member to reset rotation.

[0013] According to some embodiments of the present invention, the tensioning mechanism includes a tensioning member, which is rotatably mounted on the base frame and can drive the transmission member to reverse. The tensioning mechanism also includes a linkage member, which is rotatably mounted on the base frame about the rotation axis of the rotation shaft. The linkage member is connected to the transmission member and rotates synchronously. The tensioning member is provided with a linkage groove about the rotation axis of the rotation shaft.

[0014] According to some embodiments of the present invention, the tensioning mechanism further includes a tensioning reset member, which is disposed between the base frame and the tensioning member and is used to drive the tensioning member to reset and rotate.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 7 The components of this utility model are: base frame 100, rotating component 200, locking component 300, tensioning mechanism 400, and winding elastic element. The rotating assembly 200 includes a rotating shaft 210 and a flexible guardrail 220. The rotating shaft 210 is rotatably mounted on the base frame 100. The flexible guardrail 220 is wound around the outside of the rotating shaft 210, with one end of the flexible guardrail 220 attached to the rotating shaft 210 and the other end extending outwards. When the rotating shaft 210 rotates clockwise, the flexible guardrail 220 unfolds; when the rotating shaft 210 rotates counterclockwise, the flexible guardrail 220 retracts. A locking assembly 300 is mounted on the base frame 100 and can switch between a locked state and an unlocked state. In the locked state, the locking assembly 300 restricts the clockwise rotation of the rotating shaft 210 and allows it to rotate counterclockwise. In the unlocked state, the rotating shaft 210 can rotate both clockwise and counterclockwise. A tensioning mechanism 400 is mounted on the base frame 100. When the locking assembly 300 is in the locked state, the tensioning mechanism 400 can drive the rotating shaft 210 to rotate counterclockwise. A winding elastic element is mounted on the base frame 100 and can drive the rotating shaft 210 to rotate counterclockwise.

[0023] The locking assembly 300 includes a transmission member 310 and a locking member 320. The transmission member 310 is movably disposed on the base frame 100 along the rotation axis of the rotation shaft 210 and has a downward state and an upward state. The transmission member 310 is rotatably disposed on the base frame 100 about the rotation axis of the rotation shaft 210. At least two ratchet teeth 311 are provided on the outer side of the transmission member 310. The locking member 320 is provided with a pawl 321. The locking member 320 is movably disposed on the base frame 100 and can engage the pawl 321 with the ratchet teeth 311 to lock the locking assembly 300, and can disengage the pawl 321 from the ratchet teeth 311 to unlock the locking assembly 300. In the downward state, the transmission member 310 is in transmission engagement with the rotation shaft 210 and rotates synchronously. In the upward state, the transmission member 310 is separated from the rotation shaft 210.

[0024] Specifically, the winding elastic element can be a coil spring or a torsion spring, etc., to apply a winding force to the rotating shaft 210.

[0025] In the embodiments, reference is made to Figure 3 and Figure 4 The locking assembly 300 includes a transmission member 310 and a locking member 320. The transmission member 310 is movably disposed on the base frame 100 along the rotation axis of the rotation shaft 210 and has a downward state and an upward state. The transmission member 310 is rotatably disposed on the base frame 100 about the rotation axis of the rotation shaft 210. At least two ratchet teeth 311 are arranged on the outer side of the transmission member 310. The locking member 320 is provided with a pawl 321. The locking member 320 is movably disposed on the base frame 100 and can engage the pawl 321 with the ratchet teeth 311 to lock the locking assembly 300, and can disengage the pawl 321 from the ratchet teeth 311 to unlock the locking assembly 300. In the downward state, the transmission member 310 is in transmission cooperation with the rotation shaft 210 and rotates synchronously. In the upward state, the transmission member 310 is separated from the rotation shaft 210.

[0026] When the locking element 320 engages with the transmission element 310, i.e., when the pawl 321 and ratchet 311 are engaged, the locking assembly 300 is in a locked state. Since the transmission element 310 engages with and rotates synchronously with the rotating shaft 210, the locking element 320 restricts the forward rotation of the rotating shaft 210 through the transmission element 310. The structure of the ratchet 311 and pawl 321 allows the transmission element 310 and the rotating shaft 210 to rotate in one direction or in reverse. When the locking element 320 separates from the transmission element 310, i.e., when the pawl 321 and ratchet 311 separate, the locking assembly 300 is in an unlocked state, and the transmission element 310 can rotate freely. The locking assembly 300 described above, in the locked state, can restrict the forward rotation of the rotating shaft 210 while allowing it to rotate in reverse. Its structural feasibility is good, and it provides a physical basis for the use of the tensioning mechanism 400.

[0027] Specifically, two, three, four, or more ratchet teeth 311 can be arranged on the outer side of the transmission component 310, which can be selected by those skilled in the art according to actual needs. Specifically, the locking component 320 is provided with a first gear, and the end of the rotating shaft 210 is provided with a second gear. The locking component 320 achieves synchronous rotation by engaging the first gear with the second gear of the rotating shaft 210. It is conceivable that the locking component 320 can also achieve synchronous rotation by contacting the rotating shaft 210 through a friction wheel.

[0028] In the embodiments, reference is made to Figure 3 and Figure 6 The locking assembly 300 also includes a toggle switch 330 and a first elastic member 340. The toggle switch 330 is movably disposed on the base frame 100 and can avoid or drive the locking member 320 to separate from the transmission member 310. The first elastic member 340 is disposed between the base frame 100 and the locking member 320 and is used to drive the locking member 320 to abut against the transmission member 310.

[0029] When the toggle switch 330 drives the locking member 320 to separate from the transmission member 310, the locking assembly 300 is in the unlocked state; when the toggle switch 330 avoids the transmission member 310, the first elastic member 340 automatically drives the locking member 320 to abut against the transmission member 310, thus locking the locking member 320. The aforementioned locking assembly 300 is simple and convenient to operate. Specifically, the toggle switch 330 is slidably connected to the base frame 100 via a sliding block structure. It is conceivable that the toggle switch 330 can also be movably connected to the base frame 100 via, for example, a guide post / sleeve structure.

[0030] In the embodiments, reference is made to Figure 2 and Figure 4 The locking assembly 300 also includes a limiting member 350 and a second elastic member 360. The limiting member 350 is movably disposed on the base frame 100 and can restrict or allow the transmission member 310 to switch from a downward state to an upward state. The second elastic member 360 is disposed between the base frame 100 and the transmission member 310 and is used to drive the transmission member 310 to move from the downward state to the upward state. When the transmission member 310 is in the downward state, the limiting member 350 restricts the transmission member 310 from moving upward, keeping the transmission member 310 rotating synchronously with the rotating shaft 210. When the limiting member 350 no longer restricts the transmission member 310 from moving upward, the second elastic member 360 automatically drives the transmission member 310 to move upward. The locking assembly 300 described above requires minimal manual operation and has a high degree of automation.

[0031] Specifically, both the first elastic element 340 and the second elastic element 360 are springs; alternatively, the first elastic element 340 and the second elastic element 360 can be sheet springs, elastic blocks or other elastic elements.

[0032] In the embodiments, reference is made to Figure 3 and Figure 4 The limiting member 350 is movably disposed on the base frame 100 along the rotation axis of the rotating shaft 210 and has a downward state and an upward state. The limiting member 350 is stacked on the upper side of the transmission member 310. The limiting member 350 is rotatably disposed on the base frame 100 around the rotation axis of the rotating shaft 210 and has a first angular position and a second angular position. The base frame 100 is provided with a first stop block 110. When the limiting member 350 is in the upward state, the first stop block 110 restricts the limiting member 350 to be in the first angular position. When the limiting member 350 is in the downward state, the limiting member 350 can rotate to switch between the first angular position and the second angular position. In the second angular position, the limiting member 350 is located below the first stop block 110 and restricts the limiting member 350 from moving upward.

[0033] The limiting member 350 is stacked on top of the transmission member 310. When the limiting member 350 moves downward, it synchronously drives the transmission member 310 downward, and both enter the downward state. Subsequently, the limiting member 350 rotates from the first angle position to the second angle position, preventing the limiting member 350 from moving upward and keeping the limiting member 350 and the transmission member 310 in the downward state. At this time, the first elastic member 340 drives the locking member 320 to engage with the transmission member 310, so that the locking assembly 300 enters the locked state. When the limiting member 350 rotates back from the second angle position to the first angle position, and the toggle member 330 pushes the locking member 320 away from the transmission member 310, the limiting member 350 and the transmission member 310 can move upward to the upward state. The aforementioned locking assembly 300 reduces the risk of the transmission member 310 separating from the rotating shaft 210 due to accidental upward movement and improves the operational stability of the locking assembly 300.

[0034] In the embodiments, reference is made to Figure 3 and Figure 4 The toggle switch 330 has a lever 331 arranged along the rotation axis of the rotation shaft 210. The lever 331 is opposite to the locking member 320. The limiting member 350 is provided with a mating hole, and the lever 331 passes through the mating hole. The toggle switch 330 can drive the limiting member 350 to swing. When the limiting member 350 is in the downward position, the limiting member 350 can be indirectly moved by the toggle switch 330, so that the limiting member 350 switches between the first angle position and the second angle position. The toggle switch 330 pushes the locking member 320 to rotate through the lever 331. The structure is compact and the operation is simplified, without the need to operate the toggle switch 330 and the limiting member 350 separately.

[0035] In the embodiments, reference is made to Figure 2The locking assembly 300 also includes a button 370 and a third elastic member 380. The button 370 is slidably disposed on the base frame 100 along the rotation axis of the rotation shaft 210 and has a downward state and an upward state. When the button 370 moves downward, it can drive the limiting member 350 and the transmission member 310 to move downward. The third elastic member 380 is disposed between the button 370 and the limiting member 350 and is used to drive the button 370 to move upward. The button 370 is provided with a second stop block 371. When the button 370 is in the upward state, the second stop block 371 restricts the limiting member 350 from rotating from the second angle position to the first angle position. When the button 370 is in the downward state, the second stop block 371 avoids the limiting member 350.

[0036] The button 370 is located above the limiting member 350. When the button 370 is pressed down, it pushes the limiting member 350 and the transmission member 310 downwards, allowing the limiting member 350 to rotate to the second angle position. After the user releases the button 370, the third elastic member 380 drives the button 370 to move upwards and reset, preventing the second stop from rotating the limiting member 350 to the first angle position, thus keeping the limiting member 350 and the transmission member 310 in the downward-moving state. When the button 370 is not pressed, the risk of the limiting member 350 rotating due to external factors is avoided, and the toggle 330 is also prevented from being accidentally moved, thus avoiding accidental locking. Specifically, the third elastic member 380 is a spring; it is conceivable that the third elastic member 380 could also be, for example, a spring sheet or an elastic rubber block. Specifically, the button 370 is slidably connected to the guide hole of the base frame 100.

[0037] Specifically, the button component 370 is provided with a clearance groove. When the limiting component 350 is in the first angle position, the limiting component 350 is embedded in the clearance groove, making the layout of the two more compact and preventing the limiting component 350 from rotating at will.

[0038] In the embodiments, reference is made to Figure 6 The locking assembly 300 also includes a rotary reset member 390, which is disposed between the transmission member 310 and the base frame 100 and can drive the transmission member 310 to reset rotation. This allows the rotary reset member 390 to drive the transmission member 310 to rotate back to its initial angular position after the locking member 320 separates from the transmission member 310, facilitating the next locking and tensioning. Specifically, the rotary reset member 390 is a spring. It is conceivable that the rotary reset member 390 could also be, for example, a torsion spring or a coil spring.

[0039] In the embodiments, reference is made to Figures 6 to 7The tensioning mechanism 400 includes a tensioning element 410, which is rotatably mounted on the base frame 100 and can drive the transmission element 310 to reverse. By having the user rotate the tensioning element 410, the transmission element 310 is driven to reverse. In conjunction with the locking element 320, the transmission element 310 is restricted to the angular position after reversal, thereby further tensioning the flexible fence 220. The structure is simple and the operation is convenient.

[0040] In the embodiments, reference is made to Figure 7 The tensioning mechanism 400 includes a linkage 420, which is rotatably mounted on the base frame 100 about the rotation axis of the rotation shaft 210. The linkage 420 is connected to the transmission component 310 and rotates synchronously. The tensioning component 410 is provided with a linkage groove 411 about the rotation axis of the rotation shaft 210. The linkage 420 is provided with a linkage block 421, which is located in the linkage groove 411 and can slide along the linkage groove 411. When the tensioning component 410 rotates, it can push the linkage block 421 to rotate through the end wall of the linkage groove 411.

[0041] Initially, the linkage block 421 is located at the first end of the linkage groove 411. After the locking component 300 locks the rotating shaft 210, the user moves the tensioning member 410 so that the tensioning member 410 abuts against the linkage block 421 through the first end of the linkage groove 411, driving the linkage member 420 and the transmission member 310 to rotate synchronously at a certain angle. Then the tensioning member 410 resets and rotates. After resetting, the linkage block 421 is located at the second end of the linkage groove 411.

[0042] In the above-described transmission method, after the tensioning element 410 drives the transmission element 310 to reverse, the angle of the tensioning element 410 returns to its original state, resulting in a better performance.

[0043] In the embodiments, reference is made to Figure 7 The tensioning mechanism 400 also includes a tension reset member 430, which is disposed between the base frame 100 and the tensioning member 410 and is used to drive the tensioning member 410 to reset rotation. By setting the tension reset member 430, when the tensioning member 410 drives the linkage member 420 and the transmission member 310 to rotate at a certain angle, the elastic reset member can drive the tensioning member 410 to reset rotation independently, improving the degree of automation.

[0044] Specifically, the tension reset element 430 is a spring. It is conceivable that in other embodiments, the tension reset element 430 may also be a torsion spring or a coil spring, etc.

[0045] It is conceivable that in other embodiments, the tensioning mechanism 400 may also be other structures. For example, the tensioning mechanism 400 may be a turntable fixedly connected to the transmission member 310, which directly drives the transmission member 310 to reverse a certain angle.

[0046] Specifically, in this embodiment, the linkage 420 has a rod body arranged along the rotation axis of the rotation shaft 210, and the transmission component 310 has a mating hole through which the rod body passes, enabling both to rotate synchronously and the transmission component 310 to move up and down relative to the linkage 420. The tensioning component 410 is rotatably connected to the base frame 100; the linkage 420 is rotatably connected to the tensioning component 410 through a hole-shaft mating, and is indirectly rotatably mounted on the base frame 100; the transmission component 310 is indirectly rotatably mounted and slidably mounted on the base frame 100 through the linkage 420; a pivot is provided at the upper end of the transmission component 310, the limiting component 350 is pivotally connected to the pivot, and the button component 370 is also slidably mated to the pivot.

[0047] It is conceivable that in other embodiments, the linkage 420, tensioning member 410, transmission member 310, limiting member 350 and button member 370 may also be directly slidably or rotatably connected to the base frame 100.

[0048] Specifically, the tensioned soft door barrier of this utility model is used as follows. Initially, the locking component 300 is in the unlocked state, the button component 370, the limiting component 350 and the transmission component 310 are in the upward state, the transmission component 310 is separated from the rotating shaft 210, the limiting component 350 is in the first angle position, and the locking component 320 is separated from the transmission component 310.

[0049] Locking process: During the extension of the flexible barrier 220 to the predetermined length, the retractable elastic element initially tensions the flexible barrier 220; then, the user presses the button 370 with one hand, causing the button 370, the limiting element 350, and the transmission element 310 to move down synchronously to switch to the downward state, so that the transmission element 310 meshes with the rotating shaft 210. Then, the user moves the toggle 330 with the other hand, and the toggle 330 avoids the locking element 320, so that the locking element 320 is driven by the first elastic element 340, so that the pawl 321 and the ratchet 311 are engaged, and the toggle 330 simultaneously drives the limiting element 350 to swing from the first angle position to the second angle position. The limiting element 350 remains in the downward state under the action of the first stop block 110 to keep the transmission element 310 in the downward state. Then, the user releases the button 370 and the toggle 330, and the button 370 moves up and rebounds under the action of the third elastic element 380.

[0050] Tensioning process: The user manually swings the tensioning element 410 at a certain angle. During the rotation of the tensioning element 410, the linkage element 420, and the transmission element 310 by a predetermined angle, the pawl 321 disengages from the current ratchet 311 and engages with the subsequent ratchet 311, thereby maintaining the rotating shaft 210 in the angular position after further tensioning. Afterwards, the tensioning reset element 430 drives the tensioning element 410 to reset its rotation.

[0051] Unlocking process: The user presses button 370 with one hand to the downward position, allowing limit member 350 to reset to the first angle position. Then, the user uses the other hand to toggle switch 330 to reset, causing limit member 350 to reset to the first angle position. At the same time, toggle switch 330 pushes locking member 320 to reset, separating locking member 320 from transmission member 310. The user then releases toggle switch 330 and button 370. Under the action of second elastic member 360, transmission member 310 and limit member 350 automatically move upward to the upward position, separating transmission member 310 from rotating shaft 210. At this time, rotating reset member 390 relaxes, driving transmission member 310 to reset and rotate to the initial angle position.

[0052] It is conceivable that in other embodiments, the locking component 300 may also be a directly movable pawl 321, with a ratchet directly provided at one end of the rotating shaft 210. The pawl 321 engages with the ratchet to enter the locking state, so that the transmission component 310 can rotate in one direction when locked. When the pawl 321 is moved to disengage from the ratchet, it enters the unlocking state. Alternatively, the locking component 300 may also be an elastic ball, with a mating wheel provided on the rotating shaft 210. When the elastic ball engages with the mating wheel, the rotating shaft 210 is locked. At this time, the user can apply more force to the rotating shaft 210 through the tensioning mechanism 400 to drive it to reverse until the elastic ball re-engages with the mating wheel.
