Description

Technical Field

[0001] This invention relates to the field of stage equipment technology, and in particular to performance boats suitable for use in indoor theaters. Background Technology

[0002] As living standards continue to improve, audiences have increasingly higher demands for the quality of artistic performances. Theater stage props, as an indispensable part of performance equipment, play a crucial role in the overall effect, and performance boat props are a common type of stage prop used in performances.

[0003] Existing boat props are generally flat products or projections of boat images, lacking three-dimensionality and realism. Audiences cannot perceive the performance effects resulting from special scene changes, hindering the presentation of scene effects. While some use physical boat props, these are large, occupying limited theater space and leading to low venue utilization. Summary of the Invention

[0004] To address the above needs, this invention provides a performance boat suitable for indoor theaters. The folding hull device and the lifting hull reduce the space required for the performance boat device in the vertical direction, which can better utilize the limited space of the theater, allowing other performance devices to have relatively sufficient space and reducing costs.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A performance boat suitable for indoor theaters includes a hull section and a hull. The hull section includes at least one hull device, which comprises a truss with an outer surface layer on its outer side. Several lifting cables are connected to the truss. The lifting cables are connected to a winch to raise and lower the hull section, lowering it when needed and raising it to conceal it when not in use. The truss is arranged in an arc shape, and the number of hull devices can be selected as needed to create a partial or complete hull section. In a complete hull section, the hull devices are symmetrically arranged forward, backward, left, and right, forming a hull shape around the entire structure.

[0007] The hull includes at least one hull device, which includes a base. A lower hull assembly and an upper hull assembly are sequentially arranged on the base. The lower hull assembly includes a lower hull support, on which an active push rod and a track plate with a track groove are provided. A follower push rod is hinged to the movable end of the active push rod, and a sliding shaft that can move in the track groove is provided at the hinge. The upper hull assembly includes a lower folding plate and an upper folding plate. The lower folding plate is hinged to both the lower hull support and the upper folding plate. A follower hinge plate is provided on the lower folding plate and hinged to the upper end of the follower push rod. A cantilever arm is provided on the upper folding plate, and a balance rod is hinged to the lower end of the cantilever arm. The lower end of the balance rod is hinged to the lower hull support. The main push rod is hinged to the lower hull support. When needed, the main push rod pushes the follower push rod, which slides along the track groove to generate an upward thrust, pushing the lower folding plate connected to the follower hinge plate to open upward. At the same time, the upper folding plate slowly opens under the tension of the balance rod. After fully opening, the outer sides of the lower hull support, lower folding plate and upper folding plate are spliced ​​together. The number of hull devices can be selected as needed to achieve partial or complete hull. The hull devices of the complete hull are symmetrically arranged on the left and right sides, and the whole hull is formed by encircling the hull.

[0008] Preferably, the hull device includes a lower hull assembly and an upper hull assembly, each comprising one or more hinged truss sections of varying lengths, with a foldable outer layer between the trusses. In use, the lower hull assembly and the upper hull assembly are lowered to different heights via lifting cables, and the foldable outer layer unfolds to present the hull shape. When not in use, the lower hull assembly and the upper hull assembly are raised via lifting cables, and the foldable outer layer folds down.

[0009] Preferably, both ends of the truss of the lower hull assembly and the upper hull assembly are respectively provided with linear tracks above the hinge points. A traveling trolley is mounted on the linear tracks, and the bottom of the traveling trolley is provided with lifting point wheels for the lifting cables to pass through. This allows for the movement of the hull device. By controlling the movement of the corresponding traveling trolley, the hull device can be moved horizontally, allowing for swaying to form specific combined shapes, thus making the structure more three-dimensional and realistic.

[0010] Preferably, the linear track has two sets of first steering wheels above it and a set of second steering wheels at each end. A traction cable connects to both ends of the traveling trolley via the two sets of first and second steering wheels. The traction cable is connected to a winch, and the reciprocating movement of the traveling trolley is achieved by winding and unwinding the traction cable.

[0011] Preferably, the linear track is made of H-beams, and the traveling trolley is equipped with traveling wheels that roll along the flanges of the H-beams and guide wheels that abut against the end faces of the H-beam flanges. The guide wheels ensure that the traveling trolley disengages from the linear track.

[0012] Preferably, the outer layer and the foldable outer layer are screens, and the unfolded screens can support light and shadow presentation effects.

[0013] Preferably, at least one set of midships assemblies is provided between the lower hull assembly and the upper hull assembly. The truss length of the midships assemblies is between that of the lower hull assembly and the upper hull assembly, and a foldable outer layer is provided between each truss.

[0014] Preferably, the trusses of the lower hull assembly, upper hull assembly, and middle hull assembly are arranged side by side at one end, and the side-by-side ends share a common straight track, with a corresponding number of lifting point wheels at the bottom of the traveling trolley on it.

[0015] Preferably, there are two track plates arranged symmetrically side by side, with the hinge of the active push rod and the follower push rod located between the two track plates, and the two ends of the sliding shaft located in the track grooves of the two track plates respectively.

[0016] Preferably, the lower and upper folding plates have X-shaped sides, with several side folding plates between each side. The side folding plates are hinged to adjacent lower and upper folding plates, and to each other. The lower folding plate, upper folding plate, and each side folding plate are spliced ​​together and can be unfolded or folded in conjunction.

[0017] Preferably, the base is equipped with casters at the bottom, and a counterweight is provided on the side of the base away from the upper hull assembly. When unfolded, the outer sides of the lower hull assembly and the upper hull assembly are located on one side of the base and tilt upward and outward, forming the contour curve of the hull. The counterweight can prevent the hull assembly from tipping over.

[0018] The advantages of this invention are: its three-dimensional and realistic structure allows the audience to experience the performance effects produced by the changes in special scenes, which is conducive to the display of scene effects; it is suitable for indoor spaces, and the folding hull device and the lifting hull reduce the space required for the performance boat device in the vertical direction, which can make better use of the limited space of the theater, so that other performance devices have relatively sufficient space, reducing costs, and it can also be flexibly applied to the original theater, using the original space to perform new plays. Therefore, it achieves the purpose of energy saving and consumption reduction and improving the effective utilization rate of the venue. Attached Figure Description

[0042] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0043] Example 1: As Figure 1-3 As shown, a performance boat suitable for use in an indoor theater includes a hull section and a hull section. The hull section includes at least one hull device 10, which includes a truss 11. The outer surface of the truss 11 is provided with an outer layer 12, and several lifting cables 13 are connected to the truss 11.

[0044] Combination Figure 4-11 As shown, the hull of the ship includes at least one hull device 20. The hull device 20 includes a base 21, on which a lower hull assembly 22 and an upper hull assembly 23 are sequentially arranged. The lower hull assembly 22 includes a lower hull support 24. The lower hull support 24 is provided with an active push rod 25 and a track plate 26 with a track groove 26.1. The movable end of the active push rod 25 is hinged to a follower push rod 27, and a sliding shaft 28 that can move in the track groove 26.1 is provided at the hinge. There is a certain angle between the track groove 26.1 and the active push rod 25. The upper hull assembly 23 includes a lower folding plate 29 and an upper folding plate 210. The lower folding plate 29 is hinged to the lower hull support 24 and the upper folding plate 210 respectively. The lower folding plate 29 is provided with a follower hinge plate 211 that is hinged to the upper end of the follower push rod 27. The upper folding plate 210 is provided with a cantilever arm 212. The lower end of the cantilever arm 212 is hinged to a balance rod 213. The lower end of the balance rod 213 is hinged to the lower hull support 24.

[0045] The track plate 26 consists of two pieces arranged symmetrically side by side. The hinge of the active push rod 25 and the follower push rod 27 is located between the two track plates 26. The two ends of the sliding shaft 28 are respectively located in the track grooves 26.1 of the two track plates 26.

[0046] In addition, the base 21 is provided with casters 215 at the bottom and a counterweight 216 on the side of the base 21 away from the upper hull assembly 23.

[0047] Combination Figure 10 As shown, the follower hinge plate 211 is fixed to the lower part of the lower folding plate 29, and the height of the fixed edge exceeds half the height of the lower folding plate 29.

[0048] Combination Figure 11 As shown, the height and upper edge tilt angle of the different foldable hull devices 20 are different. A certain number of hull devices 20 are arranged in sequence to form the hull of one side of the boat. The upper edge is crescent-shaped. The two sides are symmetrically arranged to form a complete hull.

[0049] The working process of Embodiment 1 is as follows: When the performance boat is not in use, the hull device 10 is located on top of the stage, and the hull device 20 is located on the side of the stage. When needed, the hull device 20 is sequentially moved to a specific position on the stage to enclose it, such as... Figure 4-6 As shown, the active push rod 25 drives the upper hull assembly 23 from a folded state to an unfolded state, and the hull device 10 descends to combine with the hull device 20 to form a complete performance boat. After use, the hull device 10 rises, and the active push rod 25 drives the upper hull assembly 23 from an unfolded state to a folded state, and it moves horizontally to the side of the stage.

[0050] Example 2: Figure 12-14 As shown, the difference from Embodiment 1 is that the ship's side device 10 includes a lower ship's side assembly 14 and an upper ship's side assembly 15. The lower ship's side assembly 14 and the upper ship's side assembly 15 each include one or more hinged trusses 11 of different lengths, and a foldable outer layer 16 is provided between the trusses 11.

[0051] Combination Figure 15-20 As shown, straight tracks 17 are provided above the two ends and the hinge points of the truss 11 of the lower hull assembly 14 and the upper hull assembly 15, respectively. A traveling trolley 18 is provided on the straight track 17, and a lifting point wheel 19 is provided at the bottom of the traveling trolley 18 for the lifting cable 13 to pass through.

[0052] The straight track 17 is provided with two sets of first steering wheels 110 above it and a set of second steering wheels 111 at each end. A traction cable 112 is provided at both ends and is connected to the two ends of the traveling trolley 18 after passing through the two sets of first steering wheels 110 and second steering wheels 111 respectively.

[0053] The linear track 17 is made of H-beams, and the traveling trolley 18 is equipped with traveling wheels 113 that roll along the flange of the H-beams and guide wheels 114 that abut against the end face of the flange of the H-beams.

[0054] The outer layer 12 and the foldable outer layer 16 are curtains.

[0055] Example 3: Figure 13-16 As shown, based on implementation column two, at least one set of midships hull assembly 115 is provided between the lower hull assembly 14 and the upper hull assembly 15.

[0056] The trusses 11 of the lower hull assembly 14, upper hull assembly 15 and middle hull assembly 115 are arranged side by side at one end, and the side-by-side ends share a straight track 17. The bottom of the traveling trolley 18 on the track is provided with a corresponding number of lifting point wheels 19.

[0057] In Embodiments 2 and 3, the operation of the hull device 10 is as follows: when the performance boat is not in use, such as... Figure 15 As shown, the hull assembly 10 is located on top of the stage, and the trolley 18 is located at one end of the straight track 17. The various hull components are retracted close together, and the foldable outer layer 16 is folded. When needed, as... Figure 13-14 and Figure 16 As shown, the traveling trolley 18 moves to the other end of the straight track 17, causing the trusses 11 of each ship's side component to sway. At the same time, each ship's side component descends to a different height, with the lower ship's side component 14 being the lowest and the upper ship's side component 15 being the highest. The foldable outer layer 16 unfolds, forming the ship's side of the performance boat. After use, the trolley moves in the opposite direction to return to its initial unused state.

[0058] Example 4: Figure 12-14 As shown, the difference from Embodiment 1 is that the lower folding plate 29 and the upper folding plate 210 have X-shaped sides, and a number of side folding plates 214 are provided between the two sides. The side folding plates 214 are hinged to the adjacent lower folding plate 29 and the upper folding plate 210, and to the adjacent side folding plates 214.
