Description

Technical Field

[0001] This utility model relates to the field of theater building technology, and in particular to a cantilevered, detachable enclosure structure for theaters. Background Technology

[0002] In the design of modern performing arts buildings such as theaters, concert halls, and auditoriums, the rationality and flexibility of spatial layout are crucial for enhancing the audience experience and achieving efficient operation. Specifically, the balconies in theaters are an important component of the seating area. In many designs, stepped passageways or functional platforms are located at the front edge of the balconies or in front of the first row of seats. These areas are primarily used to manage crowd flow or serve as safe evacuation routes. However, in actual operation, especially during large performances or when the venue is full, the fixed function of these passageway areas often leads to a waste of space resources. Operators often wish to be able to flexibly convert these passageway areas into temporary seating areas according to different performance needs, in order to increase the venue's capacity and economic benefits.

[0003] To achieve this functional conversion, barriers or enclosures are typically installed at the front edge of the platform to safely isolate the new seating area from the existing structure (such as steps), or to ensure audience safety by blocking the passageway. Currently, existing technical solutions mainly include two forms: The first approach involves using fixed railings or permanent low walls. While this structure is safe and stable, its permanent nature completely fixes the spatial function, preventing quick switching between "passage mode" and "seat mode," resulting in a lack of spatial flexibility and an inability to meet diverse operational needs. The second approach uses temporary, movable barriers or simple fences. Although this solution offers some flexibility, it often has several drawbacks. Firstly, these temporary structures are less stable and may pose safety hazards. Secondly, their appearance is often difficult to coordinate with the high-standard interior decoration of the theater, and they also fail to meet the stringent standards for performance architecture in terms of acoustics and fire safety.

[0004] Therefore, there is an urgent need in this field for a new type of theater canopy enclosure solution. This solution must not only ensure the structural safety and stability and the appearance to blend with the theater environment, but also have convenient installation and disassembly functions, allowing staff to quickly change the use of the front area of ​​the canopy to improve space utilization while ensuring the safety of the audience. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies and to propose a detachable cantilevered enclosure structure for theaters. To achieve the above objective, the embodiments of this utility model adopt the following technical solution: This utility model embodiment proposes a detachable cantilevered enclosure structure for theaters, including: At least two sets of base assemblies fixed to the theater cantilever structure, each base assembly including at least one anchoring element; The enclosure unit is located between two sets of base components and includes a support frame, an outer finish, and a top handrail. The outer finish is located on the outer periphery of the support frame, the top handrail is connected to the top of the support frame, and the support frame is provided with a safety lock mounting cavity. The locking mechanism is located within the safety lock mounting cavity and connected to the support frame. The locking mechanism is used to cooperate with the anchoring element to lock the enclosure unit onto the base assembly.

[0006] Preferably, it also includes a baffle and multiple rollers, with the rollers evenly distributed at the bottom of the support frame, and the baffle connected to the bottom of the support frame and close to the top surface of the theater cantilever structure.

[0007] Preferably, the anchoring element includes an anchor rod and an anchoring spring, the base assembly is provided with an anchoring cavity, one end of the anchor rod is located in the anchoring cavity, and the other end of the anchor rod extends outward under the support of the anchoring spring; The locking mechanism includes a mounting base, a handle, a linkage mechanism, a return spring, and a stop rod. The mounting base is connected to the support frame. One end of the handle, the linkage mechanism, the first return spring, and one end of the stop rod are respectively located inside the mounting base. The end of the handle inside the mounting base is connected to the linkage mechanism. The linkage mechanism is connected to the end of the stop rod inside the mounting base. The first return spring is used to limit the stop rod. When the enclosure unit is connected to the base assembly, the stop rod and the anchor rod abut against each other.

[0008] Preferably, the two sets of base components are provided with limiting grooves opposite each other, and the enclosure unit is provided with a limiting block that is adapted to the limiting groove. When the enclosure unit is connected to the base component, the limiting block is engaged in the limiting groove.

[0009] Preferably, the side of the exterior facing the audience seating includes an acoustic diffusion structure integrally formed with an elastic core material, and a surface decorative fabric or leather covering the elastic core material.

[0010] Preferably, the acoustic diffusion structure is a serrated profile with a predetermined depth.

[0011] Preferably, the support frame is a rigid frame made of metal profiles, and the support frame includes at least vertical support members and inclined support members for resisting lateral thrust.

[0012] Preferably, the top handrail is a tubular component, which is fixedly installed on the top of the support frame and has an outer cladding covering the base of the top handrail.

[0013] Beneficial effects: This utility model provides a detachable, cantilevered enclosure structure for theaters. By setting a base assembly fixed to the theater's cantilevered structure and enclosure units detachably installed between the base assemblies and equipped with a locking mechanism, it achieves a unified solution for secure and stable locking and convenient disassembly of the enclosure structure. This solution effectively overcomes the problems of fixed railings in existing technologies, which result in rigid spatial functions and poor flexibility. It also solves the defects of temporary fences, such as structural instability, low safety factor, or incompatibility with the theater environment. The specialized cooperation between the locking mechanism and the anchoring elements on the base assembly ensures high stability and reliability of the enclosure units after installation, with safety standards far exceeding those of simple temporary fences, effectively protecting audience safety. More importantly, the design of this locking and anchoring structure enables rapid installation and disassembly of the enclosure units, allowing operators to easily switch between "passage mode" and "seat mode" according to performance needs, significantly improving the theater's space utilization and operational flexibility.

[0018] Example This embodiment discloses a detachable, cantilevered enclosure structure for theaters. Please refer to [link / reference]. Figures 1 to 4 .in, Figure 1 This is a transverse sectional view of the detachable cantilevered enclosure structure for theaters proposed in this embodiment, which clearly shows the installation and locking relationship between the enclosure unit 3 and the base components 1 on both sides. Figure 2 This is an application scenario diagram of this embodiment, showing the application state in which the enclosure structure is installed at the front edge of the theater stage to block the stepped passage (or seats) in front. Figure 3 This is a transverse sectional view of the enclosure unit 3 proposed in this embodiment, which shows in detail its internal support frame 4, outer surface 5, top handrail 6, and bottom rollers 10 and baffles 9. Figure 4 for Figure 1 The enlarged view in section A shows the cooperation and locking principle between the locking mechanism 8 and the anchoring element 2.

[0019] Specifically, refer to Figure 1 and Figure 2 The theater cantilever-type detachable enclosure structure of this embodiment has a basic structure including at least two sets of base components 1 fixed on the theater cantilever structure (e.g., the concrete floor or side wall of the cantilever), and enclosure units 3 detachably installed between the two sets of base components 1.

[0020] First, the base assembly 1 is the foundation for the stable installation of the enclosure structure. In this embodiment, at least two sets of base assemblies 1 are provided, which are permanently and strongly fixed to the cantilever structure of the theater, for example, by embedded parts or heavy-duty chemical anchors. These two sets of base assemblies 1 are arranged opposite each other, defining the installation position of the enclosure unit 3. As one of the core features of this utility model, the base assembly 1 includes at least one anchoring element 2. This anchoring element 2 is the key interface for locking with the enclosure unit 3, and its structure will be described in detail below in conjunction with preferred embodiments.

[0021] Secondly, the enclosure unit 3 is the main component for achieving spatial division. The enclosure unit 3 is located between two sets of base components 1, and its dimensions are designed to ensure that it can fit snugly with the base components 1 after installation. The enclosure unit 3 mainly includes a support frame 4, an outer surface 5, and a top handrail 6.

[0022] Reference Figure 3 The supporting frame 4 is the "skeleton" of the enclosure unit 3, forming the main load-bearing structure. The outer surface 5 is located on the outer perimeter of the supporting frame 4 and is the surface that visitors most frequently come into contact with and see. It not only serves a decorative purpose but also integrates acoustic and safety protection functions. The top handrail 6 is connected to the top of the supporting frame 4, providing support for visitors and serving as the top boundary of the enclosure, complying with building safety regulations.

[0023] To achieve the core function of "detachability," this embodiment includes a locking and unlocking device on the enclosure unit 3. (Refer to...) Figure 4 The support frame 4 has a safety lock mounting cavity 7 on its side end (i.e., the end closest to the base assembly 1). The safety lock mounting cavity 7 is a space reserved inside the frame to accommodate the locking mechanism 8.

[0024] The locking mechanism 8 is located within the safety lock mounting cavity 7 and is integrated with the support frame 4 by means of bolts, welding, or snap-fit. The locking mechanism 8 is used to cooperate with the anchoring element 2 on the base assembly 1 to securely lock the enclosure unit 3 onto the base assembly 1.

[0025] In practice, when a theater needs to open up the passageway in front of the platform (such as...) Figure 2 When the stepped area (as shown) is converted into a seating area, the staff pushes the barrier unit 3 to the predetermined installation position (i.e., between the two sets of base assemblies 1). Through the mechanical cooperation of the locking mechanism 8 and the anchoring element 2, the barrier unit 3 is quickly and securely locked into place, forming a safe barrier. When it is necessary to restore the passage function, the staff only needs to operate the locking mechanism 8 (e.g., through a concealed handle) to unlock it, and then remove and store the barrier unit 3. This design balances the needs of structural stability and ease of operation.

[0026] To further optimize this technical solution, this embodiment also provides a series of preferred technical details: As a preferred embodiment, to facilitate the installation, movement, and positioning of the heavy-duty fencing unit 3, its bottom structure has been optimized. Please refer to... Figure 3 The enclosure structure also includes baffle strips 9 and multiple rollers 10. The rollers 10 are evenly distributed at the bottom of the support frame 4. These rollers 10 are preferably high-load-bearing, silent omnidirectional or directional rollers, which reduce friction when the enclosure unit 3 moves on the ground (e.g., the theater's wooden floor or carpet), allowing staff to push the enclosure unit 3 and improving installation and dismantling efficiency. The baffle strips 9 are connected to the bottom end of the support frame 4, and their bottom edges are close to the top surface of the theater's cantilever structure after installation. The baffle strips 9 (e.g., flexible rubber strips or brush strips) serve multiple functions: firstly, they can cover the rollers 10, making the bottom of the enclosure visually more complete; secondly, they can prevent small items (such as mobile phones, pens, etc.) from accidentally rolling into the bottom of the enclosure; and thirdly, they can, to some extent, block airflow and sound, and provide tolerance for uneven ground.

[0027] As a preferred embodiment, the specific mechanical structure of the core components for locking, the anchoring element 2 and the locking mechanism 8, is defined in detail to achieve a reliable semi-automatic locking and manual unlocking function. Please refer to... Figure 4 This is the key to the mechanical design of this utility model.

[0028] First, the anchoring element 2 is defined as follows: an anchoring cavity 13 is provided on the main structure of the base assembly 1 (e.g., a steel plate fixed to the ground). The anchoring element 2 specifically includes an anchor rod 11 and an anchoring spring 12. One end of the anchor rod 11 (e.g., a solid steel column) is located in the anchoring cavity 13, and the anchoring spring 12 (e.g., a high-strength compression spring) is also accommodated in the anchoring cavity 13 and abuts against the inner end of the anchor rod 11. The other end of the anchor rod 11 extends outward (i.e., toward the enclosure unit 3) under the abutting force of the anchoring spring 12. This design makes the anchor rod 11 act like an elastic, retractable locking pin.

[0029] Accordingly, the locking mechanism 8 is defined as follows: the locking mechanism 8 includes a mounting base 14, a handle 15, a linkage mechanism 16, a first return spring 17, and a stop rod 18. The mounting base 14 is fixed to the safety lock mounting cavity 7 inside the support frame 4 by bolts or other means, serving as the base of the entire locking mechanism 8. The handle 15 is the interface for manual operation, and most of its structure is hidden inside the mounting base 14. One end of the handle 15, one end of the linkage mechanism 16, one end of the first return spring 17, and one end of the stop rod 18 are respectively pivotally or slidably disposed within the mounting base 14. The end of the handle 15 inside the mounting base 14 is connected to the linkage mechanism 16 via a pin. The linkage mechanism 16 (e.g., a set of crank connecting rods) is connected to the end of the stop rod 18 inside the mounting base 14. The first return spring 17 (e.g., a tension spring or torsion spring) is connected between the abutment rod 18 (or linkage mechanism 16) and the mounting base 14 to limit the abutment rod 18, keeping it in a preset position when not in operation. When the enclosure unit 3 is connected to the base assembly 1, the abutment rod 18 interacts with the anchor rod 11 to achieve locking. The abutment rod 18 has a positioning hole 27 of a specific shape in the corresponding direction. The specific working process is as follows: During installation (automatic locking): The worker pushes the enclosure unit 3 with rollers 10 closer to the base assembly 1. The front end (preferably a bevel) of the enclosure unit 3 first contacts the outwardly extending anchor rod 11. As the enclosure unit 3 continues to be pushed in, the front end of the enclosure unit 3 continuously applies pressure to the anchor rod 11, which overcomes the elasticity of the anchoring spring 12, forcing the anchor rod 11 to gradually retract into the anchoring cavity 13. During this process, the head of the anchor rod 11 slides along the side (or guide surface) of the enclosure unit 3. When the enclosure unit 3 is pushed to the predetermined installation position, the positioning hole 27, which is located in the direction corresponding to the abutment rod 18, moves exactly to the position where it is fully aligned with the anchor rod 11. At this time, the anchor rod 11 is ejected under the spring action of the anchoring spring 12 and penetrates into the positioning hole 27, forming a firm pin-type lock. At this time, the anchor rod 11 is locked with the positioning hole 27, making it impossible for the enclosure unit 3 to be pulled out, and the installation is completed.

[0030] During disassembly (manual unlocking): The operator presses (or pulls) handle 15. Handle 15, via linkage mechanism 16, drives the abutment 18 to produce a specific movement (e.g., translation or slight rotation within mounting base 14). This movement is designed to apply a "push-out" or "extrusion" lateral shear force to the anchor rod 11 through the edge of its positioning hole 27. This force forces the head of the anchor rod 11 to overcome the elasticity of the anchoring spring 12, disengage from the positioning hole 27, and retract into the anchoring cavity 13. Once the anchor rod 11 is pushed out of the positioning hole 27, it no longer locks the abutment 18, and the locking of the enclosure unit 3 is released, allowing the operator to pull the enclosure unit 3 off the base assembly 1 and remove it. After releasing handle 15, the first return spring 17 automatically resets the abutment 18 and handle 15, preparing for the next locking.

[0031] This preferred solution provides an effective and secure locking method that ensures both ease of installation (pushing in locks) and controllability of unlocking (requires special operation).

[0032] As a preferred embodiment, to further improve the guidance during installation and the final structural stability of the fencing unit 3, and to prevent the fencing unit 3 from shaking after locking, refer to... Figure 1 Limiting grooves 19 are provided on the opposite sides of the two sets of base assemblies 1. Correspondingly, limiting blocks 20 adapted to the limiting grooves 19 are provided on the sides of the enclosure unit 3 (e.g., the edges of the support frame 4). During the connection between the enclosure unit 3 and the base assembly 1, the limiting blocks 20 slide into the limiting grooves 19 and eventually engage. This design, like a drawer slide, firstly ensures the accurate positioning of the enclosure unit 3 during the pushing process, allowing the locking mechanism 8 and the anchoring element 2 to align; secondly, after locking, the cooperation of the limiting grooves 19 and the limiting blocks 20 can share the lateral impact force that the enclosure unit 3 may receive, working together with the locking mechanism 8 to form a stable multi-point supported structure.

[0033] As a preferred option, considering the high requirements for architectural acoustics in venues such as theaters and concert halls, this embodiment has functionally optimized the structure of the exterior finish 5. (Refer to...) Figure 3 The outer surface 5 faces the audience seating area (i.e., Figure 3The structure on the right side is not merely a simple decorative panel, but includes an acoustic diffusion structure 22 integrally formed from an elastic core material 21. The elastic core material 21 is also covered with a surface decorative fabric or leather. The elastic core material 21 is preferably a high-density polyurethane acoustic foam or molded sponge, a material with excellent sound absorption properties that can absorb some environmental noise, while its elasticity also provides impact cushioning, improving safety. The surface decorative fabric (such as sound-permeable fabric) or leather ensures that its appearance is consistent with the theater's interior decoration style and meets fire safety and other regulatory requirements.

[0034] As a further optimization of the above scheme, the specific shape of the acoustic diffusion structure 22 was defined. (Refer to...) Figure 3 The surface of the acoustic diffusion structure 22 is not planar, but rather a serrated profile 24 with a predetermined depth. This serrated profile 24 is a common acoustic diffuser structure; its uneven, calculated repeating structure can scatter incident sound waves (especially mid-to-high frequency sound waves) in multiple different directions, thereby helping to avoid acoustic defects such as sound focusing, standing waves, and flutter echoes. This helps to create a more uniform and natural sound field environment in the audience area, improving the acoustic quality of the theater. This approach of integrating acoustic functions into the enclosure design reflects the integration and professionalism of this solution.

[0035] As a preferred option, to ensure that the enclosure unit 3 has sufficient rigidity and strength to withstand the horizontal thrust of crowds as specified in the standards (a mandatory safety requirement in public places such as theaters), the internal structure of the support frame 4 was optimized. (Refer to...) Figure 3 The supporting frame 4 is a rigid frame constructed from high-strength metal profiles (such as Q235 or Q355 square steel tubes, rectangular tubes, or specially made 6-series / 7-series aluminum profiles) through welding or bolting. This rigid frame ensures the integrity and deformation resistance of the enclosure unit 3. Furthermore, the supporting frame 4 internally includes at least vertical support members 25 and inclined support members 26 for resisting lateral thrust. The vertical support members 25 primarily bear the weight of the enclosure unit 3 and the vertical pressure of the top handrail 6. The inclined support members 26 play a crucial role, forming multiple stable triangular structural units together with the vertical support members 25 and other transverse members. This triangular truss design effectively decomposes and safely transfers the horizontal thrust from the audience side (i.e., the exterior finish 5 side) to the locking mechanisms at the bottom and sides of the frame, thereby ensuring that the enclosure unit 3 remains stable even under accidental impact.

[0036] As a preferred option, the structure of the top armrest 6 has also been optimized both aesthetically and functionally. (Refer to...) Figure 3The top armrest 6 is preferably a tubular component, such as a round or oval solid wood tube, stainless steel tube, or leather-covered metal tube, which is fixedly installed on the top of the support frame 4 to provide a comfortable and continuous grip. Its distinctive feature is that the outer surface 5 (particularly its internal elastic core 21) extends upward and covers the base 23 of the top armrest 6. The base 23 is the connecting transition component between the top armrest 6 and the support frame 4. This covering design creates a seamless and smooth overall shape between the armrest 6 and the lower outer surface 5, avoiding abrupt transitions and gaps between the armrest and the panel, thus improving the aesthetics, unity, and craftsmanship of the design.

[0037] In summary, this embodiment provides a detachable cantilever enclosure structure for theaters through the systematic integration of the aforementioned structural and functional components. This structure, through the cooperation of the base assembly 1 and the enclosure unit 3 with the locking mechanism 8, provides the enclosure unit with convenient "push-in to lock" and "manual unlock" functions while ensuring structural safety and stability. Combining the convenient mobility of the rollers 10, the guiding function of the limiting block 20, the functionality of the acoustic diffusion structure 22, and the reliable safety of the rigid support frame 4, this solution effectively resolves the contradiction between spatial flexibility and safety stability in the theater cantilever area, possessing good practical value and market prospects.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
