Description

Technical Field

[0001] This utility model belongs to the field of public facilities technology, and specifically relates to a railing with an automatic retractable bench. Background Technology

[0002] In today's world, where the refined design and human-centered approach to urban public facilities are increasingly valued, the functional singularity of existing road railings has become a prominent shortcoming. The vast majority of them only fulfill the basic functions of isolation and protection, with fixed forms and limited uses. This singularity leads to specific usage conflicts in densely populated urban spaces, especially in narrow areas such as winding riverside walkways, historic urban alleys, or side streets in bustling commercial districts. Because the width of the passageways is already very limited, it is almost impossible to allocate space for fixed rest seats to ensure necessary traffic flow. This often leaves tourists who have been strolling for a long time, the elderly who need a short rest, or pedestrians who are physically exhausted facing the predicament of "nowhere to stop," greatly affecting the travel experience of citizens and the rest-friendly nature of urban public spaces. This design deficiency exposes the inadequacy of existing public facilities in terms of multifunctional integration and intensive space utilization.

[0003] Faced with this widespread demand, existing technological fields have indeed made some attempts and explorations to integrate seating functions into railings. These solutions mainly fall into two categories: one is to add a fixed seat plate to the top or side of the railing, and the other is to use a manually operable folding seat. However, each has its inherent drawbacks. While fixed seats have a simple structure, their permanently unfolded state continuously occupies the already limited horizontal or vertical space, becoming an obstacle to passage when not in use, easily causing collisions, and affecting the overall simplicity and aesthetics of the railing. Folding seats, while solving the problem of continuous space occupation to some extent, often require users to perform a series of relatively cumbersome operations such as unlocking, forcefully folding down, manually resetting after standing up, and then locking again. This process is extremely inconvenient for people with mobility impairments or pedestrians carrying heavy objects, and in actual use, due to inconvenience in resetting or human negligence, the seats often fail to retract in time, making them also a "semi-permanent" obstacle. More importantly, these added moving parts, such as hinges, latches, and support rods, are exposed to outdoor wind and rain for a long time. Not only are their structures relatively complex and their manufacturing costs higher, but they also face the risks of easy corrosion, wear and mechanical failure, resulting in low reliability and high maintenance costs. Summary of the Invention

[0004] To overcome the above problems, the purpose of this utility model is to provide a railing with an automatic retractable stool. By using an automatic spring-loaded retractable mechanism, the powerful spring stored energy when the stool was in a horizontal use state, and drove the stool to automatically return to a vertical retractable state after the load was removed. This allows the stool to automatically and smoothly return to its original position after use, avoiding any interference with passage.

[0005] The technical solution of this utility model is as follows: a railing with an automatically retractable stool, comprising a railing body, a stool portion, and an automatic spring-loaded retraction mechanism. The stool portion has an internal hollow structure, and the automatic spring-loaded retraction mechanism is located inside the stool portion. The stool portion is rotatably connected to the railing body through the automatic spring-loaded retraction mechanism. The automatic spring-loaded retraction mechanism includes a fixed shaft, an irregularly shaped fixing component and a strong spring sequentially sleeved on the outside of the fixed shaft, and the stool portion is hinged to the railing body through the fixed shaft. One end of the strong spring is connected to the fixed shaft, and the other end is connected to a strong spring stool surface fixing component. The strong spring stool surface fixing component is fixedly connected to the stool portion. The strong spring stores energy when the stool portion is in a horizontal use state and drives the stool portion to automatically return to a vertical retraction state after the load is removed.

[0006] The main body of the railing includes multiple railing grids, and a railing base plate is provided at the bottom of each railing grid. The railing base plate has reserved mounting holes, and adjacent railing grids are connected by plug-in connection.

[0007] The railing grid is 1.2m high, 8mm thick, and 120mm wide, with a grid gap of ≤100mm.

[0008] The bench includes a bench with reinforcing ribs inside the bench surface and a pre-reserved opening on the bench surface on the side of the bench near the main body of the railing.

[0009] The bench is located 0.45m above the ground on the main body of the railing. The bench seat is 0.45m wide and has a rotation range of 0° to 90°.

[0010] A strong spring fixing shaft fixing component is provided on the outside of the fixed shaft, and one end of the strong spring is connected to the strong spring fixing shaft fixing component.

[0011] The irregularly shaped fixing component is provided with an irregularly shaped fixing component opening, and the fixing shaft passes through the irregularly shaped fixing component opening and is rotatably connected to the railing body.

[0012] The surface of the main body of the railing is coated with an epoxy resin anti-rust coating, and the thickness of the epoxy resin anti-rust coating is not less than 1.5 mm.

[0013] The technical advantages of this utility model are as follows: 1. By using an automatic rebound storage mechanism, the powerful spring in this utility model stores energy when the seat is in a horizontal use state, and drives the seat to automatically return to a vertical storage state after the load is removed. This ensures that the seat can automatically and smoothly return to its original position after use, avoiding any interference with passage. 2. The main surface of the railing of this utility model is coated with an epoxy resin anti-rust coating, which can effectively resist rainwater and dust erosion and extend its service life.

[0025] like Figures 1-9 As shown, a railing with an automatically retractable stool includes a railing body, a stool section, and an automatic spring-loaded retraction mechanism. The stool section has an internal hollow structure, and the automatic spring-loaded retraction mechanism is located inside the stool section. The stool section is rotatably connected to the railing body via the automatic spring-loaded retraction mechanism. The automatic spring-loaded retraction mechanism includes a fixed shaft 7 and irregularly shaped fixing components 11 and a strong spring 8 sequentially sleeved on the outside of the fixed shaft 7. The stool section is hinged to the railing body via the fixed shaft 7. One end of the strong spring 8 is connected to the fixed shaft 7, and the other end is connected to a strong spring stool surface fixing component 10. The strong spring stool surface fixing component 10 is fixedly connected to the stool section. The strong spring 8 stores energy when the stool section is in a horizontal use state and drives the stool section to automatically return to a vertical retraction state after the load is removed.

[0026] In practical use, this utility model can be widely installed in areas with limited space, such as urban walkways, park corridors, riverbank railings, or narrow alleyways. The main body of the railing consists of multiple railing grids 1, and the seat part has an internal hollow structure with a built-in automatic spring-loaded storage mechanism. When pedestrians need to rest, they only need to gently press down on the seat part, and the seat will rotate around the fixed axis 7 to a horizontal position. At this time, the powerful spring 8 is twisted and stores elastic potential energy. After the pedestrian sits down, the spring maintains stable force; when the pedestrian gets up and leaves, the load is removed, and the spring quickly releases energy, driving the seat to automatically and smoothly rotate back to the vertical storage state, without occupying the passage width, which is especially suitable for the elderly, children, or citizens carrying luggage. Example 2
