Description

Technical Field

[0001] This invention relates to the field of amusement park equipment technology, and more particularly to a pressure bar restraint device used in amusement park equipment. Background Technology

[0002] Most amusement park ride seats are equipped with restraint bars to protect riders and prevent them from falling off. Existing restraint bar devices (such as the applicant's earlier patent application, publication number CN 103100158 A) typically include a bar that can swing inwards and outwards. Swinging the bar inwards towards the seat restrains the rider. The bar uses a ratchet and pawl structure to achieve unidirectional rotation and lock to the maximum open position. However, in these restraint bar devices, the pawl often only engages with the ratchet through spring pressure. If the spring is too loose or even fails, the pawl may not be able to engage tightly with the ratchet, posing a safety risk of the bar accidentally opening.

[0003] In addition, some existing lever restraint devices use cylinders or other actuators to directly drive the pawl to swing. If the actuator gets stuck and cannot retract, the pawl will also be interfered with by the actuator and cannot disengage from the ratchet. It is difficult to manually move the pawl, which makes manual emergency rescue extremely difficult.

[0004] Furthermore, in some existing weight bar restraint devices, the weight bars are usually installed in front of the tourist's toes or calves, or in a row, which results in problems such as large size, inconvenience in opening and closing the weight bars, and discomfort for tourists.

[0005] This invention was made based on this situation. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressure bar restraint device with higher safety and reliability for use in amusement facilities.

[0007] This invention is achieved through the following technical solution:

[0008] To solve the above-mentioned technical problems, the present invention provides a pressure bar restraint device applied to amusement facilities, including a mounting base fixed to the amusement facility, a pressure bar rotatably connected to the mounting base that can swing back and forth relative to it and restrain tourists on the seats, a ratchet plate concentric with its rotation axis on the pressure bar, a first ratchet tooth on the ratchet plate, a pawl on the mounting base, and a hinge shaft rotatably connecting the middle of the pawl and the mounting base, the front of the pawl having a second ratchet tooth that can engage with the first ratchet tooth; an elastic element that can elastically press the pawl against the mounting base to make the second ratchet tooth engage with the first ratchet tooth, and an unlocking device that can act on the pawl and disengage the second ratchet tooth from the first ratchet tooth; the center of gravity G of the pawl is located behind the hinge shaft, so that the second ratchet tooth engages with the first ratchet tooth under the weight of the pawl itself.

[0009] To further address the technical problem addressed by this invention, the present invention provides a lever restraint device for use on amusement rides. The unlocking device includes a lever and an unlocking driver. The middle part of the lever is rotatably connected to a mounting base, and the front part of the lever extends below the rear part of the pawl. The output end of the unlocking driver is hinged to the rear part of the lever. When the unlocking driver drives the rear part of the lever to swing backward, the front part of the lever pushes upward against the rear part of the pawl, thereby driving the second ratchet to disengage from the first ratchet.

[0010] To further address the technical problem to be solved by this invention, this invention provides a lever restraint device for use on amusement facilities, wherein the unlocking actuator is a linear actuator hinged to the mounting base.

[0011] To further solve the technical problem to be solved by the present invention, the present invention provides a bar restraint device for use in amusement facilities, wherein the elastic element is located above the rear part of the pawl, and the elastic element presses down on the rear part of the pawl.

[0012] To further solve the technical problem to be solved by the present invention, the present invention provides a bar restraint device for use in amusement facilities, wherein the lower end of the bar is provided with a turntable, a rotating shaft is provided between the turntable and the mounting base to rotatably connect the two, the ratchet plate is concentric with the rotating shaft, and the ratchet plate is detachably connected to the turntable.

[0013] To further solve the technical problem to be solved by the present invention, the present invention provides a pressure bar restraint device applied to amusement facilities, wherein the side wall of the turntable is provided with a mounting groove with the same shape as the ratchet plate, the ratchet plate is fitted into the mounting groove, and a screw is provided between the ratchet plate and the mounting groove to connect the two.

[0014] To further solve the technical problem to be solved by the present invention, the present invention provides a pressure bar restraint device applied to amusement facilities, wherein there are two ratchet plates and two correspondingly fixed pawls, the two ratchet plates are arranged side by side and respectively installed on the two side walls of the turntable, and the first ratchet teeth on the two ratchet plates are staggered by half a tooth profile.

[0015] To further address the technical problem to be solved by the present invention, the present invention provides a lever restraint device for use in amusement facilities, wherein each of the pawls is provided with at least two second ratchet teeth, which simultaneously engage with the corresponding first ratchet teeth.

[0016] To further address the technical problem addressed by this invention, the present invention provides a bar restraint device for use on amusement facilities, wherein a tension spring is provided between the front part of the lower end of the bar and the mounting base, and the upper part of the bar can swing forward under the action of the tension spring.

[0017] To further solve the technical problem to be solved by the present invention, the present invention provides a pressure bar restraint device applied to amusement facilities, wherein the mounting base is provided with a limiting pin located behind the lower end of the pressure bar, and a limiting plate is provided at the rear of the lower end of the pressure bar. When the pressure bar swings backward to the limit position, the limiting pin blocks the limiting plate.

[0018] To further address the technical problem to be solved by the present invention, the present invention provides a lever restraint device for use on amusement facilities, wherein the front part of the pawl is provided with a rescue hole for inserting a rod-shaped tool and moving the pawl backward.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. In this invention, the second ratchet tooth at the front of the pawl, under the action of the elastic element, remains engaged with the first ratchet tooth on the ratchet plate, thereby locking the pressure bar. The pressure bar, under the action of the ratchet plate and the pawl, can only be pressed downwards and cannot open forwards, ensuring that the pressure bar will not be accidentally opened. Furthermore, since the center of gravity G of the pawl is located behind the hinge shaft, the center of gravity G causes the front part of the pawl to tend to swing towards the ratchet plate (upwards). Thus, even if the elastic element fails, the pawl will remain engaged with the ratchet plate under its own weight, thereby locking the pressure bar and preventing it from being accidentally opened. The pawl can lock the ratchet plate under both the action of the elastic element and its own weight. Even if the elastic element fails, it does not affect the pawl's ability to lock the ratchet plate; the pawl can still press the ratchet plate, providing double safety protection, thus making it safer and more reliable.

[0021] 2. In this invention, when the output end of the unlocking driver retracts, it causes the rear (upper) part of the lever to swing backward, thus causing the front (lower) part of the lever to swing forward, thereby pressing upward against the rear part of the pawl. This causes the front part of the pawl to swing backward, disengaging from the ratchet plate and unlocking the lever, allowing it to open forward. When the output end of the unlocking driver extends forward, the pawl re-engages with the ratchet plate under its own weight and the action of the elastic element. If the unlocking driver fails, the front part of the pawl can be manually moved backward, causing it to swing backward and disengage from the ratchet plate. In this structure, moving the front part of the pawl backward will not interfere with the movement of the pawl regardless of the state of the unlocking driver. Therefore, even if the unlocking driver is jammed, the front part of the pawl can still be moved backward to unlock the lever, making it more reliable and more conducive to emergency rescue.

[0022] 3. Because the pressure bar has a mounting groove with the same shape as the ratchet plate, it is used to fix the ratchet plate. The load of the ratchet plate can be transferred through the mounting groove, avoiding direct force on the screw, making it safer and more durable. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 5The diagram illustrates a lever restraint device used on amusement rides. This device, designed to restrain riders, includes a mounting base 1 fixed to the ride. A lever 2, rotatably connected to the mounting base 1, swings back and forth relative to the lever and restrains riders on seats. The lever 2 has a ratchet plate 3 concentric with its rotation axis, and a first ratchet tooth 31. The mounting base 1 also has a pawl 4, with a hinge shaft 5 rotatably connecting the pawl 4 and the mounting base 1. The front of the pawl 4 has a second ratchet tooth 41 that engages with the first ratchet tooth 31. An elastic element 6, capable of elastically pressing against the pawl 4 to engage the second ratchet tooth 41 with the first ratchet tooth 31, and an unlocking device 7 acting on the pawl 4 to disengage the second ratchet tooth 41 from the first ratchet tooth 31 are provided between the pawl 4 and the mounting base 1.

[0031] like Figure 5 As shown, a seat frame 1a is provided on the amusement facility, and a seat 1b is provided on the seat frame 1a. The mounting seat 1 is also on the seat frame 1a, and the mounting seat 1 is located below the seat 1b. A cover 1c is provided on the mounting seat 1 to cover and protect the structure on the mounting seat 1. Preferably, the upper end of the pressure bar 2 is provided with a soft rubber-coated tube 23 (such as...). Figure 1 , Figure 3 As shown, after the pressure bar 2 swings backward and extends into the seat 1b, the soft rubber-coated tube 23 comes into contact with the tourist's body, restricting the tourist and preventing them from detaching from the seat 1b. The pressure bar 2 of this invention is located below the seat 1b and between the tourist's legs, making the tourist more comfortable to sit in and easier to get up and sit down. The pressure bar 2 is also easier to open and close, and provides greater safety for the tourist.

[0032] like Figure 1 As shown, the center of gravity G of the pawl 4 is located behind the hinge shaft 5, so that the second ratchet 41 engages with the first ratchet 31 under the weight of the pawl 4.

[0033] In this invention, the second ratchet 41 at the front of the pawl 4, under the action of the elastic element 6, remains engaged with the first ratchet 31 on the ratchet plate 3, thereby locking the pressure bar 2. The pressure bar 2, under the action of the ratchet plate 3 and the pawl 4, can only be pressed downwards and cannot open forwards, ensuring that the pressure bar 2 will not be accidentally opened. Furthermore, since the center of gravity G of the pawl 4 is located behind the hinge shaft 5, the center of gravity G of the pawl 4 causes the front part of the pawl 4 to tend to swing towards the ratchet plate 3 (upwards in the figure). Thus, even if the elastic element 6 fails, the pawl 4 will remain engaged with the ratchet plate 3 under its own weight, thereby locking the pressure bar 2 and preventing it from being accidentally opened. The pawl 4 can lock the ratchet plate 3 under the action of the elastic element 6 and under its own weight. The failure of the elastic element 6 does not affect the pawl 4's ability to lock the ratchet plate 3; the pawl 4 can still press the ratchet plate 3, providing double safety protection, thus making it safer and more reliable.

[0034] In more specific embodiments of the present invention, such as Figure 1 As shown, the unlocking device 7 includes a lever 71 and an unlocking driver 72. The middle part of the lever 71 is rotatably connected to the mounting base 1, and the front part of the lever 71 extends below the rear of the pawl 4. The output end of the unlocking driver 72 is hinged to the rear of the lever 71. When the unlocking driver 72 drives the rear of the lever 71 to swing backward, the front part of the lever 71 presses upward against the rear of the pawl 4, thereby driving the second ratchet 41 to disengage from the first ratchet 31. When the output end of the unlocking driver 72 retracts backward, it drives the rear (upper) part of the lever 71 to swing backward, thus causing the front (lower) part of the lever 71 to swing forward, thereby pressing upward against the rear of the pawl 4. In this way, the front of the pawl 4 swings backward, thereby disengaging from the ratchet plate 3 and unlocking the lever 2, which can then open forward. When the output end of the unlocking driver 72 extends forward, the pawl 4 re-engages with the ratchet plate 3 under its own weight and the action of the elastic element 6.

[0035] It is worth noting that if the unlocking actuator 72 fails, the front part of the pawl 4 can be manually moved backward, causing it to swing backward and disengage from the ratchet plate 3. In this structure, moving the front part of the pawl 4 backward will not interfere with the movement of the pawl 4 regardless of the state of the unlocking actuator 72. Thus, even if the unlocking actuator 72 is stuck, the front part of the pawl 4 can still be moved backward to unlock the lever 2, making it more reliable and more conducive to emergency rescue.

[0036] In a more specific embodiment of the present invention, the unlocking actuator 72 is a linear actuator hinged to the mounting base 1. The unlocking actuator 72 is preferably an electric push rod, but it can also be a cylinder, gear rack, or other structure.

[0037] In a more specific embodiment of the invention, the elastic element 6 is disposed above the rear portion of the pawl 4, and the elastic element 6 presses downward against the rear portion of the pawl 4. The elastic element 6 is preferably a compression spring that presses downward against the rear portion of the pawl 4.

[0038] In a more specific embodiment of the present invention, the lower end of the pressure bar 2 is provided with a turntable 21, and a rotating shaft 8 is provided between the turntable 21 and the mounting base 1 to rotatably connect the two. The ratchet plate 3 is concentric with the rotating shaft 8.

[0039] The ratchet plate 3 is detachably connected to the turntable 21, for example, by fixing it with screws, which facilitates disassembly and maintenance.

[0040] More specifically, such as Figure 3 , Figure 4As shown, the side wall of the turntable 21 is provided with a mounting groove 211 that has the same shape as the ratchet plate 3. The ratchet plate 3 is fitted into the mounting groove 211, and a screw 212 is provided between the ratchet plate 3 and the mounting groove 211 to connect the two. That is, the pressure bar 2 is machined with a mounting groove 211 that has the same shape as the ratchet plate 3 to fix the ratchet plate 3, and the load of the ratchet plate 3 can be transferred through the mounting groove 211, avoiding direct force on the screw 212, which is safer and more durable. Moreover, the installation method of first placing the ratchet plate 3 into the mounting groove 211 and then screwing in the screw 212 is more convenient and easier to align.

[0041] In more specific embodiments of the present invention, such as Figure 3 As shown, there are two ratchet plates 3, and correspondingly two fixed pawls 4. The two ratchet plates 3 are arranged side by side and installed on the two side walls of the turntable 21. The first ratchet teeth 31 on the two ratchet plates 3 are offset by half a tooth pitch. The two ratchet plates 3 are offset by 0.5 tooth pitch in the circumferential direction, which is equivalent to doubling the adjustment level of the ratchet and pawl mechanism. This increases the adjustment accuracy of the pressure bar tube 2, ensuring that it can meet the different needs of different tourists, i.e., adapt to different body sizes. The double pawls are hinged to the mounting base 1 by a pin. During operation, only one pawl 4 is engaged with the ratchet plate 3, while the other pawl 4 is in a standby state. The standby state means that the pawl 4 is in contact with the ratchet plate 3 under its own weight but is not engaged. If one pair of ratchet and pawls fails, the other pair will take effect, providing double protection and greater safety.

[0042] In a more specific embodiment of the present invention, each pawl 4 is provided with at least two second ratchet teeth 41, which simultaneously engage with the corresponding first ratchet teeth 31. When the pawl 4 locks the ratchet plate 3, at least two second ratchet teeth 41 simultaneously engage with the first ratchet teeth 31 on the ratchet plate 3, which is equivalent to increasing the engagement safety factor by at least 100%, making it safer and more reliable.

[0043] In a more specific embodiment of the present invention, a tension spring 9 is provided between the front part of the lower end of the pressure bar 2 and the mounting base 1, and the upper part of the pressure bar 2 can swing forward under the action of the tension spring 9. After the pawl 4 and the ratchet plate 3 disengage, the pressure bar 2 is unlocked and can swing freely back and forth. At this time, under the pulling force of the tension spring 9, the pressure bar 2 can automatically spring up and open, without the user having to push the pressure bar 2 open, making it more convenient to open the pressure bar 2. Of course, the tension spring 9 can also be replaced with a gas spring or other structures.

[0044] In a more specific embodiment of the present invention, the mounting base 1 is provided with a limiting pin 11 located behind the lower end of the pressure bar 2, and a limiting plate 22 is provided at the rear of the lower end of the pressure bar 2. When the pressure bar 2 swings backward to its limit position, the limiting pin 11 blocks the limiting plate 22. The limiting pin 11 is used to limit the minimum restraint position of the pressure bar 2 (the limit position of the pressure bar 2 swinging backward); while the ratchet plate 3 is used to limit the maximum opening position of the pressure bar 2 (the maximum position of the pressure bar 2 swinging forward). Preferably, a buffer sleeve 111 is provided on the limiting pin 11. The buffer sleeve 111 is a soft rubber sleeve used to buffer impact and reduce noise. A shim 221 is provided on the limiting plate 22. By adding or removing the shim 221, the minimum restraint range of the pressure bar 2 can be adjusted; if the thickness of the shim 221 increases, the minimum restraint position is raised; if the thickness of the shim 221 decreases, the minimum restraint position is lowered.

[0045] In a more specific embodiment of the invention, the front of the pawl 4 is provided with a rescue hole 42 for inserting a rod-shaped tool and moving the pawl 4 backward. The rod-shaped tool here mainly refers to tools such as screwdrivers, levers, and round steel bars. Figure 1 As shown, in an emergency rescue, a screwdriver can be inserted into the rescue hole 42 by passing it through the pre-drilled hole on the cover 1c. The screwdriver can be used to push the pawl 4 backward, and the front part of the pawl 4 will disengage from the ratchet plate 3, thus unlocking the lever 2. It can be opened by swinging it forward, allowing the tourist to be freed from restraints and leave. Power outage rescue is convenient.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
