Description

Technical Field

[0001] This invention relates to the field of stage equipment technology, specifically to an adjustable-angle performance ring catapult. Background Technology

[0002] In some stage performances, a performance format is often designed to suit the needs of the plot: one actor throws a ring prop, while one or more other actors jump through the ring at opportune moments. This format has significant drawbacks: firstly, it requires additional actors to throw the rings; secondly, the actors' ability to perform consistently directly impacts the performance's effectiveness. Furthermore, to achieve the desired effect, multiple rings are often thrown in succession. If the actors cannot properly control the timing, force, and spacing of their throws, performance accidents may occur, greatly affecting the audience's experience.

[0003] Therefore, it is necessary to develop a throwing machine that can meet the requirements of continuous throwing to replace the existing manual throwing. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable-angle performance ring catapult that can continuously launch performance rings at different angles according to performance needs, replacing manual throwing while improving the launching effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable-angle performance ring catapult, comprising: Chassis unit; A tilting body, which is hinged to the chassis unit, has a storage compartment for accommodating the performance ring and an exit ring located on top of the storage compartment; A tilting drive unit, one end of which is hinged to the chassis unit and the other end of which is hinged to the tilting body; A filling unit is installed in the tilting body and has a filling ring holder that moves in the storage compartment along a first direction and a driving device for driving the filling ring holder. A catapult firing unit is installed inside the tilting body and located below the storage compartment. It has a firing element that moves along a second direction, which is perpendicular to the bottom surface of the tilting body, and the first direction is perpendicular to the second direction.

[0006] Furthermore, the driving device includes a lead screw, a guide rod, a chain transmission mechanism, and a drive motor; The lead screw and guide rod are arranged parallel to the first direction. The filling ring holder is threadedly installed with the lead screw and slidably installed with the guide rod. The chain drive mechanism is connected to the lead screw and the drive motor respectively.

[0007] Furthermore, there are two loading ring holders, which are arranged symmetrically; each loading ring holder has several slots for fixing the performance ring.

[0008] Furthermore, the tilting body includes a main shell and a rear cover. The rear top of the main shell is provided with a notch, and the rear cover is hinged to the notch. When the rear cover is closed, there is a certain gap between its top and the front wall of the main shell, thereby forming the exit ring.

[0009] Furthermore, an opening and closing actuator is also connected between the main shell and the rear cover.

[0010] Furthermore, the ejection firing unit includes a spring-loaded firing device, a pin device, a trigger device, and a reset device; the spring-loaded firing device is connected to the firing element, the trigger device is hinged and one end is connected to the firing element via a flexible component, and the reset device is capable of abutting the other end of the trigger device; the pin device is capable of locking or releasing the firing element; when the firing element is in a charged state, the trigger device is separated from the reset device, and when the firing element is in a released state, the trigger device is in contact with the reset device.

[0011] Furthermore, the elastic firing device includes a vertically mounted sleeve, a vertical shaft disposed in the sleeve, and a firing spring disposed in the sleeve and sleeved on the outer periphery of the vertical shaft, wherein the top of the vertical shaft is connected to the firing element; The pin device includes a horizontally arranged pin and a pin driver for driving the pin, and the firing member is provided with a slot that can be inserted into the pin.

[0012] Furthermore, two elastic firing devices are provided, and the two ends of the firing element are respectively connected to the elastic firing devices.

[0013] Furthermore, the surface of the firing element that contacts the performance ring is an arc surface, and the length of the arc surface is not less than one-fifth of the circumference of the performance ring.

[0014] Furthermore, it also includes detectors for detecting when the performance circle reaches the launch position.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) This invention will be able to replace manual throwing of performance rings, thereby realizing automatic multi-angle continuous throwing of performance rings. Through mechanical catapult technology, the speed, angle and interval of the catapult can be better controlled, thereby ensuring the performance effect of the performers and reducing the probability of performance accidents.

[0016] 2) The present invention uses a movable loading unit, which can not only load and store multiple performance rings required for the performance in an axially concentric manner to meet the storage of more performance rings with minimal space occupation, but also automatically move the performance rings to the ejection position to achieve automatic ejection.

[0017] 3) This invention uses a firing unit with an elastic element as a power storage component to launch the performance ring, and uses a pin to release the elastic force through rapid action, thereby achieving rapid launch of the performance ring. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: As Figures 1 to 11 As shown, the present invention discloses an adjustable angle performance ring catapult, including a chassis unit 1, a tilting body 2, a tilting drive unit 3, a loading unit 4, and a catapult firing unit 5.

[0022] The chassis unit 1 is a movable chassis, meaning that the chassis of the base plate unit is equipped with wheels 6 for easy movement to the performance area. Additionally, the chassis body also houses a control unit and a power supply unit, but the improvement of this invention lies in its structure, and the control and wiring methods are existing technologies, so they will not be described in detail.

[0023] The tilting body 2 is hinged to the chassis unit 1, thereby allowing the launch angle of the performance ring 38 to be changed by adjusting its tilting angle relative to the chassis unit 1. In this example, as... Figure 5 and Figure 7 As shown, as a hinged installation position, the bottom center of the tilting body 2 and the top center of the chassis body are installed through a high hinge support 7. In this way, there is a large gap between the bottom of the tilting body 2 and the top of the chassis unit 1, so that the tilting body 2 can tilt to the left or right at a certain angle, thereby enabling the performance circle 38 to be launched in two opposite directions without changing the attitude of the chassis unit 1.

[0024] The tilting body 2 has a storage compartment 8 for accommodating the performance ring 38 and an outlet 9 located on top of the storage compartment 8. Clearly, the tilting body 2 is a box-like structure, its interior used to store the performance ring 38 and other main components. To achieve the storage of the performance ring 38, such as... Figure 9 As shown, in a preferred embodiment, the tilting body 2 includes a main shell 10 and a rear cover 11. A notch is provided on the top rear side of the main shell 10, allowing the storage compartment 8 to be exposed, facilitating manual loading of the performance ring 38 into the storage compartment 8. The rear cover 11 is hinged to the notch; after loading, the rear cover 11 closes to seal the notch. In the closed state, the top of the rear cover 11 has a certain gap with the front wall of the main shell 10, forming an exit ring opening 9. That is, after the rear cover 11 is closed, the storage compartment 8 is only connected to the outside world through the exit ring opening 9. More specifically, an opening / closing actuator 12 is also connected between the main shell 10 and the rear cover 11. The opening / closing actuator 12 is an electric or pneumatic actuator, capable of automatically or assistedly opening and closing the rear cover 11.

[0025] The tilting body 2 is driven by the tilting drive unit 3 to tilt to the left or right, thereby achieving ejection in different directions. Therefore, the tilting drive unit 3 connects the tilting body 2 and the chassis unit 1. Specifically, one end of the tilting drive unit 3 is hinged to the chassis unit 1, and the other end is hinged to the tilting body 2. The tilting drive unit 3 is an electric actuator, which adjusts the angle of the tilting body 2 by controlling the extension and retraction length of the actuator.

[0026] The loading unit 4 is used to store the performance ring 38 and move the performance ring 38 to the catapult firing position. The loading unit 4 is installed in the tilting body 2 and has a loading ring holder 13 that moves in the storage compartment 8 along a first direction and a drive device 14 that drives the loading ring holder 13.

[0027] As a preferred example, such as Figure 8 As shown, the drive unit 14 includes a lead screw 15, guide rods 16, a chain drive mechanism 17, and a drive motor 18. The drive motor 18 is fixedly installed inside the tilting body 2. The lead screw 15 and guide rods 16 are both installed parallel to the first direction in the storage compartment 8 within the tilting body 2. One lead screw 15 is used in conjunction with two guide rods 16, and the lead screw 15 is symmetrically mounted on the left and right sides of the storage compartment 8 via bearings. The sprockets in the chain drive mechanism 17 are respectively mounted on the end of the lead screw 15 and on the main shaft of the drive motor 18, and the chain passes around all the sprockets to transmit power to the drive motor 18.

[0028] The lead screw 15 and guide rod 16 are arranged parallel to the first direction. The filling ring holder 13 is threadedly fitted to the lead screw 15 and slidably fitted to the guide rod 16. The chain drive mechanism 17 connects the lead screw 15 and the drive motor 18. Obviously, the two lead screws 15 rotate synchronously under the drive of the drive motor 18. The filling ring holder 13 is threadedly fitted to the corresponding lead screw 15 through the nut of the lead screw 15, so it will move along the first direction when the lead screw 15 rotates.

[0029] As a preferred embodiment, two loading ring holders 13 are provided, symmetrically arranged on the left and right sides of the storage compartment 8 to match the corresponding lead screws 15. Each loading ring holder 13 has several slots 19 for fixing the performance ring 38, all of which are equidistant along a first direction. The purpose of having two loading ring holders 13 is to support the left and right sides of the lower half of the performance ring 38 from both sides, thus providing space for the firing element 20 of the projectile firing unit 5 to contact the bottom of the performance ring 38 and complete the projectile firing. Alternatively, only one loading ring holder 13 can be provided. In this case, the width of the loading ring holder 13 should be larger to support the left and right sides of the lower half of the performance ring 38. A slot is provided in its central part, allowing the bottom of the performance ring 38 to pass downwards through the slot while the firing element 20 passes upwards through the slot to complete the projectile firing, thus achieving a clearance function.

[0030] The function of the ejection firing unit 5 is to provide the firing force, thereby launching the performance ring 38. The ejection firing unit 5 is installed inside the tilting body 2 and located below the storage compartment 8; obviously, its position corresponds to the ejection firing position of the performance ring 38. The ejection firing unit 5 has a firing element 20 that moves along a second direction; obviously, the firing element 20 can move rapidly in a short time to complete the ejection. In this invention, the second direction is perpendicular to the bottom surface of the tilting body 2, and the first direction is perpendicular to the second direction.

[0031] As a preferred example, the projectile firing unit 5 is a pneumatic firing device, which uses a high-pressure air source as a power source to achieve rapid firing of the firing element 20.

[0032] Since the firing mechanism 20 travels at a relatively high speed during firing, and the performance ring 38 is typically made of lightweight material, to avoid damage to the performance ring 38 from excessive firing force, as a preferred embodiment, the surface of the firing mechanism 20 in contact with the performance ring 38 is an arc surface, the length of which is not less than one-fifth of the circumference of the performance ring 38. By increasing the contact area with the performance ring 38, force concentration that could lead to deformation of the performance ring 38 is avoided, thus reducing the probability of damage to the performance ring 38 while providing sufficient firing force. Obviously, other methods or means can also be adopted to protect the performance ring 38, such as placing rubber pads on the contact surface to prevent rigid contact from damaging the performance ring 38.

[0033] As a preferred embodiment, the position of the performance ring 38 needs to be determined when it moves with the loading ring holder 13, so that the performance ring 38 can stop when it reaches the ejection position. After ejection, the subsequent performance rings 38 automatically take their place and wait for ejection. Therefore, the present invention also includes a detector 21 for detecting when the performance rings 38 reach the ejection position. The detector 21 is set at the position corresponding to the first performance ring 38 when the loading ring holder 13 is in the initial position. That is, when the first performance ring 38 is in the ejection position, the signal generated by the detector 21 is sent to the controller to initiate ejection. After the first performance ring 38 is ejected, the detector 21 no longer detects a signal. At this time, the controller issues a loading command, and the loading ring holder 13 moves forward. When the second performance ring 38 triggers the detector 21 to generate a signal, the loading ring holder 13 stops moving, and the second ejection is completed. This process continues until the last performance ring 38 is ejected. When the loading ring holder 13 moves to the end point, the controller sends a reset signal and the loading ring holder 13 returns to the initial position. As a preferred example, detector 21 is one of photoelectric switch, micro switch and limit switch.

[0034] Example 2: Figures 12 to 14 As shown, this embodiment differs from Embodiment 1 in that, in this embodiment, the bottom end of the tilting body 2 and the top end of the chassis unit 1 are mounted on the same side via a shorter hinge support 7. Therefore, the distance between them is smaller. The tilting drive unit 3 is hinged to the other end or near the other end. In this way, the tilting drive unit 3 can only drive the tilting body 2 to tilt in one direction, thus launching the performance ring 38 in one direction. Obviously, when it is necessary to launch the performance ring 38 in the opposite direction, the chassis unit 1 only needs to rotate 180° in place. The purpose of this design is to reduce the driving arm, thereby reducing the required driving force of the tilting drive unit 3, allowing for the selection of lower-specification and lower-priced actuators as the power source.

[0035] Another difference is that, in this embodiment, the catapult firing unit 5 is non-pneumatic. Specifically, the catapult firing unit 5 includes an elastic firing device 22, a pin device 23, a trigger device 24, and a reset device 25. The elastic firing device 22 is vertically arranged so that its firing action is consistent with the movement direction of the firing element 20. It is connected to the firing element 20, thereby driving the firing element 20 with the suddenly released elastic force. The trigger device 24 is hinged and its lower end is connected to the firing element 20 via a flexible member 26. The reset device 25 is horizontally arranged, and its movable end can abut against the upper end of the trigger device 24. The pin device 23 is horizontally arranged and is used to lock or release the firing element 20. When the firing element 20 is in the charged state, the trigger device 24 is separated from the reset device 25. When the firing element 20 is in the released state, the trigger device 24 is in contact with the reset device 25. After the pin device 23 is released, the firing element 20 is fired under the drive of the ejection firing device, moving upward to a high position. Therefore, the flexible member 26 pulls the lower end of the trigger device 24, causing the upper end of the trigger device 24 to move towards and approach or abut against the movable end of the reset device 25. It should be noted that the flexible member 26 can be guided by the pulley 37 as needed, thereby changing the direction of the traction force. At this time, when the reset device 25 drives the upper end of the trigger device 24 to reset, the lower end of the trigger device 24 pulls the firing element 20 downward to achieve reset. After the firing element 20 resets, the pin device 23 locks it in place for the next firing.

[0036] More specifically, the elastic firing device 22 includes a vertically mounted sleeve 27, a vertical shaft 28 disposed within the sleeve 27, and a firing spring 29 disposed within the sleeve 27 and sleeved around the outer periphery of the vertical shaft 28. Limiting members 30 are provided at both the upper and lower ends of the vertical shaft 28, serving to limit its movement within the sleeve 27 and to abut against the spring. That is, the limiting member 30 at the upper end of the vertical shaft 28 abuts against the upper end of the spring, receiving the elastic force to complete firing. The limiting member 30 at the lower end of the vertical shaft 28 is used to limit its movement during firing, preventing it from detaching from the sleeve 27. The top of the vertical shaft 28 is connected to the firing element 20. Two elastic firing devices 22 are provided and symmetrically arranged, with the vertical shaft 28 of each elastic firing device 22 correspondingly connected to the left and right ends of the firing element 20.

[0037] like Figure 14 As shown, the pin device 23 includes a horizontally arranged pin 31 and a pin driver 32 for driving the pin 31. The firing element 20 is provided with a sliding mounting shaft 33, which is slidably mounted in a bushing 35 located at the bottom center of the tilting body 2 via a linear bearing 34, thereby causing the firing element 20 to move in a first direction. The shaft wall of the sliding mounting shaft 33 is provided with a slot 36 that can be inserted into the pin 31.

[0038] As a preferred example, both the pin driver 32 and the reset device 25 are electric actuators.
