Description

Technical Field

[0001] This application relates to the field of railing technology, specifically to a railing device with a convertible seat. Background Technology

[0002] Places with high pedestrian traffic are prone to accidents such as crushing and falls. By setting up isolation barriers, crowds can be effectively guided and dispersed, and passenger flow density can be reasonably distributed to avoid excessive concentration of people. This greatly reduces the probability of safety accidents such as falls and crushing caused by crowding. Isolation barriers are suitable for queuing scenarios such as subway stations, airports, and scenic spot entrances during holidays.

[0003] However, during weekdays and periods with low foot traffic, the function of isolation barriers is limited to isolation. Furthermore, the idleness of isolation barriers can lead to resource waste, as they require regular cleaning, maintenance, or replacement. Even with low usage, costs will continue to accrue. Alternatively, storing idle isolation barriers in corners or rooms will reduce space utilization. Utility Model Content

[0004] In view of this, and considering the limitations of existing isolation barriers which are limited to high-volume queuing scenarios, leading to resource waste and high costs, this application provides a barrier device with interchangeable seating. By changing the structure of the barrier, it can both divide areas and provide rest seats, avoiding the space redundancy caused by separately setting up barriers and seats, saving the cost of separately purchasing seats and barriers and subsequent maintenance costs, and also improving the user experience.

[0005] To achieve the above objectives, this application provides the following technical solution: a railing device with a convertible seat, comprising:

[0006] The isolation fence includes a first support and a second support, wherein the first support and the second support are movably connected.

[0007] Multiple support components are used to support the isolation fence;

[0008] A snap-fit ​​assembly is used to secure the first support and the support assembly. The snap-fit ​​assembly can be opened to allow the first support to rotate from a vertical position to a horizontal position.

[0009] Compared with existing technologies, the convertible seat railing device of this application changes the structure of the isolation railing, enabling the railing device to not only have an isolation function but also to be transformed into a seat according to actual needs, providing users with a place to rest. When isolation space is needed, the first support remains vertical, the second support remains vertical, and they are fixed to the support components by a buckle assembly to form a stable isolation railing; when a seat is needed, simply open the buckle assembly and rotate the first support from a vertical state to a horizontal state, with the first support forming a seat cushion and the second support forming a backrest, thus forming a seat for people to rest. This saves the cost of separately purchasing seats and railings and the subsequent maintenance costs, improves resource utilization, and enhances the user experience.

[0010] Preferably, a limiting hinge is provided between the first support and the second support. The first support is hinged to the second support through the limiting hinge, and the limiting hinge is used to limit the rotation angle of the first support.

[0011] In this embodiment, the limiting hinge can effectively limit the rotation angle of the first support, preventing it from rotating beyond the design range, so that the first support can only move within the set angle range, thereby improving the overall stability of the isolation guardrail.

[0012] Preferably, the rotation angle of the first support is in the range of 0° to 90°.

[0013] In this embodiment, when the first support rotates to 90°, the angle between the first support and the second support is 90°, forming a comfortable seat back and providing users with a good resting experience; when the first support rotates to 0°, the angle between the first support and the second support is 180°, forming a railing that can separate users and maintain the order of queuing on site.

[0014] Preferably, the support assembly includes at least two support rods and at least two columns, with the columns spaced apart at the connection between the first support and the second support, and the two support rods respectively located on both sides of the first support away from the second support rod, the support rods being used to support the first support;

[0015] The support rod has a Y-shaped structure.

[0016] In this embodiment, by setting support rods and columns, the stability and load-bearing capacity of the isolation guardrail can be effectively enhanced.

[0017] Preferably, the first support has at least one hinge hole on the side away from the support rod, and the column is hinged to the first support through the hinge hole.

[0018] In this embodiment, by providing hinge holes, the first support can rotate flexibly, which makes it convenient for users to adjust the angle of the isolation guardrail as needed. At the same time, it also makes the connection between the post and the first support more stable, avoiding loosening or damage caused by long-term use.

[0019] Preferably, the first support includes a support frame and a plurality of spaced vertical bars, both ends of which are connected to the support frame;

[0020] The second support includes a railing and multiple spaced connecting rods; one end of each connecting rod is connected to the railing, and the other end is hinged to the support frame.

[0021] The connection positions of the multiple vertical rods and the multiple connecting rods do not overlap.

[0022] In this embodiment, by setting multiple vertical poles, the user's seating area can be increased, providing a more comfortable experience.

[0023] Preferably, the latching assembly includes at least two first latching members and a second latching member;

[0024] When the first support is in a horizontal position, the first buckle is sleeved on the support frame or support rod, and the second buckle is sleeved on the vertical rod.

[0025] When the first support is in a vertical position, the first fastener is used to fix the support frame and the support rod, and the second fastener is used to fix the column and the vertical rod.

[0026] In this embodiment, the first and second fasteners work together to fix or unlock the first support and the support assembly, which facilitates the conversion of the first support between the vertical and horizontal states. Compared with the fixation of complex components such as screws and bolts, the fastener assembly is more convenient and efficient to assemble, and it is also convenient to maintain and replace.

[0027] Preferably, the second fastener includes a first mounting ring, a second mounting ring, and a connector disposed between the two, wherein the connector is provided with a groove that is recessed toward the column.

[0028] When the first support is in a vertical position, the groove corresponds to and engages with the column, and the first mounting ring and the second mounting ring are respectively sleeved on the two vertical rods adjacent to the column.

[0029] In this embodiment, by setting a groove, the groove can adaptively fit the shape of the column, ensuring a tight fit between the second fastener and the column, and preventing the column from tilting or loosening towards the side away from the user, thereby obstructing the user's passage.

[0030] Preferably, the two columns are symmetrically arranged along the center position of the support frame, and the end of the column away from the ground is hinged to the connecting rod.

[0031] In this embodiment, the symmetrical arrangement can improve the overall stability of the isolation fence structure and make its stress distribution more uniform.

[0032] Preferably, at least one horizontal bar is provided between two adjacent vertical bars, and the horizontal bar is located at the middle of the vertical bars.

[0033] In this embodiment, by setting a crossbar, the stability of the first support can be increased, and more seating surface can be provided for the user, thereby improving the user's comfort when riding. Attached Figure Description

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Please see Figure 1-8 This application provides a technical solution: a railing device for a convertible seat, including a guardrail, multiple support components 2, and a buckle assembly 3. The guardrail includes a first support 11 and a second support 12, both made of stainless steel. The first support 11 and the second support 12 are movably connected, with the second support 12 positioned above the first support 11. The multiple support components 2 support the guardrail to ensure its stability during use. The buckle assembly 3 secures the first support 11 and the support components 2. The buckle assembly 3 can be opened to allow the first support 11 to rotate from a vertical position to a horizontal position, thereby converting the guardrail from a railing 121 to a seat. The buckle assembly 3 can effectively connect and secure different components according to the different positions of the first support 11, such as horizontal or vertical, improving the flexibility and adaptability of the structure. When a seat is needed, simply open the latch assembly 3 and rotate the first support 11 from a vertical position to a horizontal position. The first support 11 then forms a seat cushion, and the second support 12 forms a backrest, creating a seat for people to rest and providing a resting space for waiting passengers. When the user needs to convert the seat back into a railing device, simply rotate the first support 11 from a horizontal position back to a vertical position and secure it using the latch assembly 3. The operation is simple and quick, saving the cost of separately purchasing seats and railings 121 and reducing subsequent maintenance costs, improving resource utilization, and enhancing the user experience.

[0047] Furthermore, such as Figures 1 to 3As shown, a limiting hinge is provided between the first support 11 and the second support 12. Multiple limiting hinges are provided, and the first support 11 is hinged to the second support 12 via these hinges. The limiting hinges limit the rotation angle of the first support 11, effectively restricting its rotation angle and preventing it from exceeding the design range. This ensures that the first support 11 can only move within a set angle range, improving the overall stability of the guardrail. Specifically, the rotation angle range of the first support 11 is 0° to 90°. When the first support 11 rotates to 90°, the angle between the first support 11 and the second support 12 is 90°, forming a comfortable seat backrest and providing a good resting experience for users. When the first support 11 rotates to 0°, the angle between the first support 11 and the second support 12 is 180°, forming a railing 121, which can isolate users and maintain order in the queue.

[0048] Furthermore, such as Figures 1 to 3 As shown, the support component 2 includes at least two support rods 21 and at least two uprights 22. The support rods 21 have a Y-shaped structure, and the uprights 22 are spaced apart at the connection between the first support 11 and the second support 12. The two support rods 21 are respectively located on both sides of the first support 11 away from the second support 12. The support rods 21 support the first support 11, effectively enhancing the stability and load-bearing capacity of the guardrail. The Y-shaped support rods 21 provide stable support and safety. The two uprights 22 are symmetrically arranged along the center of the support frame 112. The end of the upright 22 away from the ground is hinged to the connecting rod 122. The symmetrical arrangement improves the overall stability of the guardrail structure and makes its stress distribution more uniform. The hinged connection allows the uprights 22 to adapt to certain angle changes, alleviating stress concentration caused by uneven ground or external forces. It also facilitates the folding and rotation of the uprights 22, making it easier to store, transport, and transport the guardrail, improving the flexibility of use and extending the life of the guardrail.

[0049] The first support 11 has at least one hinge hole 111 on the side away from the support rod 21. The column 22 is hinged to the first support 11 through the hinge hole 111. The hinge hole 111 is located in the middle of the side of the first support 11, and the size of the hinge hole 111 is adapted to the size of the column 22. By setting the hinge hole 111, the first support 11 can rotate flexibly, which makes it convenient for users to adjust the angle of the isolation guardrail as needed. At the same time, it makes the connection between the column 22 and the first support 11 more stable, avoiding loosening or damage caused by long-term use.

[0050] Furthermore, such as Figures 1 to 3As shown, the first support 11 includes a support frame 112 and multiple spaced vertical bars 113, both ends of which are connected to the support frame 112. The second support 12 includes a railing 121 and multiple spaced connecting rods 122, one end of which is connected to the railing 121, and the other end of which is hinged to the support frame 112 via a limiting hinge. This allows the user to easily adjust the angle of the first support 11, making it easier to transition from a horizontal to a vertical position. It also makes the connection between the first support 11 and the second support 12 more stable, ensuring user safety. The connection positions of the multiple vertical bars 113 and the multiple connecting rods 122 do not overlap; that is, each vertical bar 113 is positioned between two adjacent connecting rods 122. The multiple vertical bars 113 increase the user's seating area, providing a more comfortable experience and enhancing the stability between the first support 11 and the second support 12, preventing tilting or leaning.

[0051] Among them, at least one horizontal bar 114 is provided between two adjacent vertical bars 113. The horizontal bar 114 is located in the middle of the vertical bar 113, and the two ends of the horizontal bar 114 are welded to the two adjacent vertical bars 113 respectively. That is, the connection angle between the horizontal bar 114 and the vertical bar 113 is 90°, which can increase the stability of the first support 11 and provide more seating surface for the user, thereby improving the user's comfort when riding.

[0052] like Figure 8 As shown, the limiting hinge includes a housing 132, at least two rotating shafts 131, and at least two limiting plates 133. The housing 132 has a mounting groove for accommodating the limiting plates 133. The outer diameter of the limiting plates 133 is matched with the inner diameter of the mounting groove, that is, the limiting plates 133 are in close contact with the inner wall of the housing 132. The housing 132 has at least two rotating holes in the axial direction. One end of the rotating shaft 131 passes through the rotating hole and is fixedly connected to the limiting plate 133. The other end of the rotating shaft 131 is engaged with the support frame 112. The housing 132 is at least partially engaged with the connecting rod 122 to realize the hinge between the support frame 112 and the connecting rod 122. The limiting plates 133 can limit the relative rotation of the housing 132 and the rotating shafts 131, thereby limiting the rotation angle of the first support 11.

[0053] Furthermore, such as Figures 4 to 7As shown, the snap-fit ​​assembly 3 includes at least two first snap-fit ​​pieces 31 and second snap-fit ​​pieces 32. Both first snap-fit ​​pieces 31 and second snap-fit ​​pieces 32 are made of stainless steel. When the first support 11 is in a horizontal position, the first snap-fit ​​piece 31 is sleeved on the support frame 112 or the support rod 21, and the second snap-fit ​​piece is sleeved on the vertical rod 113. When the first support 11 is in a vertical position, the first snap-fit ​​piece 31 is used to fix the support frame 112 and the support rod 21, and the second snap-fit ​​piece 32 is used to fix the column 22 and the vertical rod 113. Through the cooperation of the first snap-fit ​​piece 31 and the second snap-fit ​​piece 32, the fixing or unlocking of the first support 11 and the support assembly 2 is realized, facilitating the conversion of the first support 11 between vertical and horizontal states. Compared with the fixing of complex components such as traditional screws and bolts, the snap-fit ​​assembly 3 is more convenient and efficient to assemble, and also facilitates maintenance and replacement.

[0054] Furthermore, such as Figures 4 to 5 As shown, the second fastener 32 includes a first mounting ring 321, a second mounting ring 322, and a connector 323 disposed between the two. The two ends of the connector 323 are fixedly connected to the first mounting ring 321 and the second mounting ring 322, respectively. The connector 323 is provided with a groove 3231, which is recessed towards the column 22. When the first support 11 is in a vertical position, the groove 3231 corresponds to and engages with the column 22. The first mounting ring 321 and the second mounting ring 322 are respectively sleeved on the two vertical rods 113 adjacent to the column 22. The size of the groove 3231 is adapted to the size of the column 22. The groove 3231 can adaptively fit the shape of the column 22 to ensure a tight fit between the second fastener 32 and the column 22. This can prevent the column 22 from tilting or loosening towards the side away from the user, thereby obstructing the user's passage. The first mounting ring 321 and the second mounting ring 322 can be opened, allowing the user to open the second fastener 32 as needed. At the same time, the second fastener can be easily disassembled for maintenance or replacement. The inner diameter of the first mounting ring 321 and the second mounting ring 322 is slightly larger than the outer diameter of the vertical rod 113 to ensure that they can be tightly and securely fitted onto the vertical rod 113, while avoiding excessive tightness that would make disassembly difficult.

[0055] Among them, such as Figures 6 to 7As shown, the first fastener 31 includes a third mounting ring 311, a fourth mounting ring 312, and a connecting part 313 disposed between the two. The two ends of the connecting part 313 are fixedly connected to the third mounting ring 311 and the fourth mounting ring 312 respectively. The third mounting ring 311 and the fourth mounting ring 312 can be opened, which makes it convenient for the user to open the first fastener 31 as needed. At the same time, it is also convenient to disassemble the first fastener for maintenance or replacement. The inner diameter of the third mounting ring 311 and the fourth mounting ring 312 is slightly larger than the outer diameter of the support frame 112 to ensure that they can be tightly and securely fitted onto the support frame 112, while avoiding excessive tightness that would make disassembly difficult.
