Technical Field

[0001] This utility model belongs to the field of public facilities technology, and specifically relates to a public seat. Background Technology

[0002] In today's society, public places such as parks, stations, shopping malls, and libraries are important venues for people's daily activities, leisure, travel, and communication. These places typically require a large number of public seats to meet people's needs for rest, waiting, or short stays. Traditional public seating designs mainly focus on providing basic seating functions. Their structure is relatively simple, generally consisting of a seat and a backrest, aiming to provide users with comfortable posture support and alleviate physical fatigue.

[0003] However, with the improvement of people's living standards and the increasing richness of social activities, people's functional needs for public places are no longer limited to basic seating. In public places, people often need to place their belongings, such as placing drinks and books when resting in a park; placing luggage when waiting at a station; and placing shopping bags when shopping in a mall. But traditional public seats lack additional storage space, so users often have to place their items on the ground or hold them in their arms, which not only causes inconvenience to users but may also lead to the loss or damage of items.

Detailed Implementation

[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1-5 As shown, the public seat of this utility model includes a seat board 1 and a seat back 2. Support legs 11 are fixed to both ends of the seat board 1, and connecting plates 12 are installed on both support legs 11. The seat back 2 is fixed between the two connecting plates 12.

[0016] A rectangular frame 21 is provided in the middle of the seat back 2, and a support plate 22 is provided in the middle of the rectangular frame 21. A pivot is provided at the bottom of the support plate 22, and the support plate 22 is rotatably connected to the rectangular frame 21 through the pivot. A locking component is provided between the support plate 22 and the rectangular frame 21.

[0017] In its initial state, the support plate 22 is located within the rectangular frame 21, together forming the seat back 2. When needed, the support plate 22 can be flipped to a horizontal position for user use.

[0018] Locking component The locking assembly includes a cavity 23 formed at the upper end of the support plate 22, a locking block 24 slidably disposed within the cavity 23, and a spring 25 disposed between the locking block 24 and the bottom of the cavity 23. A locking groove 26 matching the locking block 24 is formed on the side wall of the rectangular frame 21, and an unlocking component is provided at the upper center of the support plate 22.

[0019] Specifically, the unlocking component includes a slider 31, which is connected to the locking block 24 via a pull wire 32. A sliding rod 33, extending slidably from the upper end of the support plate 22, is connected to the upper end of the slider 31. A pressing block 34 is connected to the upper end of the sliding rod 33, and the rectangular frame 21 has a slot that matches the pressing block 34.

[0020] To facilitate the smooth entry of the locking block 24 into the locking groove 26, the locking block 24 is machined with a bevel.

[0021] Limiting component A limiting member is provided between the support plate 22 and the rectangular frame 21. The limiting member includes a circular groove in the rectangular frame 21, and the rotating shaft extends into the circular groove. An arc-shaped limiting groove 4 is provided on the side wall of the circular groove, and a limiting block 41 located in the arc-shaped limiting groove 4 is fixed to the rotating shaft. The limiting groove 4 can limit the flipping angle of the support plate 22, so that it can only flip to a horizontal state.

[0022] This public seating system, by incorporating a flip-up support plate 22, provides users with additional space without compromising the basic seating function. When flipped horizontally, the support plate 22 can be used to place items or as a small table, meeting the diverse needs of users in public spaces.

[0023] The design of the locking and unlocking components makes locking and unlocking the carrier plate 22 simple and convenient. The user only needs to press the pressing block 34 to pull the locking block 24 away from the locking groove 26 via the pull cable 32, thereby unlocking and flipping the carrier plate 22; after flipping into place, the locking block 24 automatically enters the locking groove 26 under the action of the spring 25, completing the locking.

[0024] The arc-shaped limiting groove 4 and the limiting block 41 in the limiting component cooperate to accurately limit the flipping angle of the bearing plate 22, ensuring that the bearing plate 22 can only be flipped to a horizontal state, thereby improving the stability and safety of use.

[0025] The support plate 22 is located inside the rectangular frame 21, and together with the rectangular frame 21, it forms the seat back 2. At this time, the locking block 24 enters the locking groove 26 under the action of the spring 25, and the support plate 22 is locked.

[0026] When the user needs to use the support plate 22, they press the pressing block 34. The pressing block 34 drives the slider 31 to slide via the slide rod 33. The slider 31 pulls the locking block 24 downwards via the pull wire 32, overcoming the elastic force of the spring 25, so that the locking block 24 disengages from the locking groove 26, thereby unlocking the support plate 22. Then, the user can manually flip the support plate 22, making it rotate around the pivot until the limiting block 41 reaches the end of the arc-shaped limiting groove 4. At this time, the support plate 22 flips to a horizontal state, which can be used by the user to place items or as a small table.

[0027] After use, the user manually flips the support plate 22 back to its initial position. During the flipping process, the inclined surface of the locking block 24 contacts the side wall of the rectangular frame 21. As the support plate 22 continues to flip, the locking block 24 is compressed into the cavity 23, and the spring 25 is further compressed. When the support plate 22 is fully reset, the locking block 24 re-enters the locking groove 26 under the action of the spring 25, completing the locking of the support plate 22 and restoring the seat back 2 to its normal state.

[0028] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
