Description

Technical Field

[0001] This invention relates to the field of amusement equipment technology, and more particularly to a restraint device for amusement equipment. Background Technology

[0002] Most amusement rides on the market are equipped with seats for passengers, and these seats have shoulder straps to restrain riders and prevent them from falling. However, the shoulder straps on conventional amusement rides are usually similar to those on backpacks, with the tightness adjusted by buckles. If the straps are not adjusted tight enough, it can easily lead to accidents, and manual adjustment is time-consuming and laborious. Some amusement rides on the market use a rear tensioning structure to adjust the shoulder strap tightness, but this usually involves a single tensioning structure pulling the shoulder straps from the middle on both sides. This causes the shoulder straps to be pulled inward, resulting in stress concentration and reducing their lifespan. Furthermore, current tensioning structures generally do not exert constant force on the shoulder straps. When the shoulder straps are pulled, larger riders experience greater tension, while smaller riders experience less tension, resulting in a poor user experience or inadequate protection. Currently, there is no effective solution to these problems.

[0003] This invention is based on the above circumstances. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a restraint device for amusement equipment. This restraint device can simultaneously use a first constant force tensioning device and a second constant force tensioning device to tighten the shoulder straps from both sides of the rear of the seat with a constant tension, thereby reducing the problem of stress concentration in the shoulder straps, increasing the service life of the shoulder straps, and also ensuring that the tension experienced by tourists of different body types is the same, increasing the comfort of the tourists and the safety of the amusement equipment.

[0005] This invention is achieved through the following technical solution:

[0006] A restraint device for amusement equipment includes a seat and a leg presser mounted on the seat. The front side of the seat is provided with a pair of shoulder straps for restraining the human body, and the rear side of the seat is provided with a first constant force tensioning device and a second constant force tensioning device that constantly pulls the pair of shoulder straps from the left and right sides respectively.

[0007] As described above, the restraint device of an amusement equipment includes a first constant force tensioning device comprising a first gas spring and a first guide device disposed on one side of the first gas spring and used to guide the first gas spring when pulling the shoulder strap; and a second constant force tensioning device comprising a second gas spring and a second guide device disposed on one side of the second gas spring and used to guide the second gas spring when pulling the shoulder strap.

[0008] As described above, a restraint device for an amusement ride includes a seat frame, a backrest, a cushion, and a pressure rod connected to the seat frame. The leg support is mounted on the pressure rod. The lower part of the seat frame has a first mounting hole, and both ends of the first mounting hole have force-enhancing mounting sleeves for extending the lever arm.

[0009] As described above, a restraint device for an amusement ride includes a first guide device comprising a sleeve mounted on a seat and a piston rod that moves along the inner wall of the sleeve. The piston rod has a traction frame for pulling the shoulder strap at one end away from the sleeve. One end of the first gas spring is connected to the traction frame and used to pull the traction frame, and the other end is connected to the sleeve.

[0010] As described above, in a restraint device for an amusement device, the piston rod has a protrusion at one end inside the sleeve, and the sleeve has a stepped structure that restricts the piston rod from sliding out of the sleeve.

[0011] As described above, a restraint device for an amusement ride includes a traction frame comprising a base, on which two side plates are spaced apart. Bolts are installed on the two side plates, penetrating them and locked with nuts. A gap is provided between the bolts and the base for the shoulder strap to pass through.

[0012] As described above, in a restraint device for an amusement ride, one end of the pair of shoulder straps is connected to each other and to the leg presser, while the other end passes through the seat and the gap in sequence and is then connected to the seat.

[0013] As described above, in the restraint device of an amusement device, the first constant force tensioning device and the second constant force tensioning device pull the shoulder strap simultaneously.

[0014] As described above, in a restraint device for an amusement ride, a housing is provided on the rear side of the seat component. The first constant force tensioning device, the second constant force tensioning device, the first guide device, and the second guide device are all located inside the housing. An installation plate is provided between the seat component and the housing. The installation plate is installed on the seat component, and the housing is installed on the installation plate.

[0015] As described above, in a restraint device for an amusement device, the seat frame is provided with a mounting groove for mounting a force-enhancing mounting sleeve at a position corresponding to the first mounting hole. The force-enhancing mounting sleeve includes an insertion end that inserts into the mounting groove and an extension end that extends out of the mounting groove and is used to increase the lever arm. The force-enhancing mounting sleeve is provided with a second mounting hole at a position corresponding to the first mounting hole, which penetrates the insertion end and the extension end and is connected to the first mounting hole.

[0016] As described above, a restraint device for an amusement device includes at least one first pin hole on the mounting groove, in which a pin is inserted. The insertion end, on the side that is in contact with the bottom of the mounting groove, has a second pin hole for inserting the pin to restrict the rotation of the force-enhancing mounting sleeve.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The rear of the seat is equipped with a first constant force tensioning device and a second constant force tensioning device that tighten the shoulder straps from both the left and right sides. By using the first and second constant force tensioning devices simultaneously to tighten the shoulder straps with a constant force from both the left and right sides of the rear of the seat, the force on the shoulder straps is more even, thereby reducing the problem of excessive stress concentration on the shoulder straps, increasing the service life of the shoulder straps, and also ensuring that the tension experienced by tourists of different body types is the same, so that larger people do not experience greater tension, and smaller people do not experience less tension, thereby increasing the comfort of tourists and the safety of amusement equipment.

[0019] 2. A first guide device is provided on one side of the first gas spring, and a second guide device is provided on one side of the second gas spring. The first guide device and the second guide device guide the first gas spring and the second gas spring to pull the shoulder strap, respectively. This prevents the first gas spring and the second gas spring from deviating from the trajectory when pulling the shoulder strap, which would cause the shoulder strap to flip or fold and cause excessive stress concentration. At the same time, it also prevents the first gas spring and the second gas spring from swinging and failing to pull the shoulder strap with constant force, thereby increasing the service life of the shoulder strap.

[0020] 3. A mounting plate is provided between the seat component and the housing. The mounting plate is installed on the seat component, and the housing is installed on the mounting plate. Compared with the housing being directly installed on the seat component, the mounting plate can be shaped according to the external contour of the seat component. Installing the housing through the middle mounting plate can make the housing installation more compact.

[0021] 4. The first mounting hole at the bottom of the seat frame is equipped with force-enhancing mounting sleeves at both ends. The force-enhancing mounting sleeves can be used to lengthen the lever arm, thereby reducing the thickness of the lower part of the seat component. By installing the force-enhancing mounting sleeves on a thinner seat component, the lever arm can be increased, thus achieving the effect of thickening the lower part of the seat component.

[0032] 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:

[0033] like Figures 1 to 8 The illustrated restraint device for an amusement ride includes a seat 1 and leg-pressing components 2 mounted on the seat 1. The front of the seat 1 has a pair of shoulder straps 5 for restraining the user. The rear of the seat 1 has a first constant-force tensioning device and a second constant-force tensioning device that simultaneously pull the shoulder straps 5 with constant force from both sides. The first and second constant-force tensioning devices pull the shoulder straps 5 synchronously. By simultaneously applying a constant pulling force from both sides of the rear of the seat 1, the shoulder straps 5 are tightened more evenly, thus reducing stress concentration and increasing their lifespan. This also ensures that users of different body types experience the same pulling force, preventing larger users from experiencing excessive force and smaller users from experiencing insufficient force, thereby increasing user comfort and the safety of the amusement ride.

[0034] The first constant force tensioning device includes a first gas spring 61 and a first guide device 71 located on one side of the first gas spring 61 for guiding the first gas spring 61 when it pulls the shoulder strap 5. The second constant force tensioning device includes a second gas spring 62 and a second guide device 72 located on one side of the second gas spring 62 for guiding the second gas spring 62 when it pulls the shoulder strap 5. The first guide device 71 and the second guide device 72 guide the first gas spring 61 and the second gas spring 62 when they pull the shoulder strap 5, thereby preventing the first gas spring 61 and the second gas spring 62 from deviating from their trajectory when pulling the shoulder strap 5, causing the shoulder strap 5 to fold or overlap and resulting in excessive stress concentration. At the same time, it also prevents the first gas spring 61 and the second gas spring 62 from swinging and failing to pull the shoulder strap 5 with constant force, thereby increasing the service life of the shoulder strap 5.

[0035] The first guiding device 71 includes a sleeve 711 mounted on the seat 1 and a piston rod 712 that moves along the inner wall of the sleeve 711. The piston rod 712 has a traction frame 713 for pulling the shoulder strap 5 at one end away from the sleeve 711. One end of the first gas spring 61 is connected to the traction frame 713 and is used to pull the traction frame 713, and the other end is connected to the sleeve 711. The piston rod 712 has a protrusion 7121 at one end inside the sleeve 711. The sleeve 711 has a stepped structure 7111 that restricts the piston rod 712 from sliding out of the sleeve 711. The first gas spring 61 extends and retracts along the piston movement direction of the piston rod 712.

[0036] The traction frame 713 includes a base 7131, on which two side plates 7132 are spaced apart. Bolts 7133, which pass through the two side plates 7132 and are locked with nuts, are installed on the two side plates 7132. A gap 7134 is provided between the bolts 7133 and the base 7131 for the shoulder straps 5 to pass through. One end of the pair of shoulder straps 5 is connected to each other and connected to the leg presser 2. The other end passes through the seat 1 and the gap 7134 in sequence and is connected to the seat 1. The traction frame 713 is pulled by the first gas spring 61, thereby tightening the shoulder straps 5.

[0037] The second guide device 72 has the same structure as the first guide device 71. The connection method and principle between the second guide device 72 and the connecting part 51 and the second gas spring 62 are the same as those between the first guide device 71 and the connecting part 51 and the first gas spring 62.

[0038] The seat component 1 is also provided with a housing 8 on its rear side. The first gas spring 61, the second gas spring 62, the first guide device 71, and the second guide device 72 are all located in the housing 8. A mounting plate 9 is provided between the seat component 1 and the housing 8. The mounting plate 9 is mounted on the seat component 1, and the housing 8 is mounted on the mounting plate 9. The seat component 1 includes a seat frame 100 and a backrest 101, a seat cushion 102, and a pressure rod 103 connected to the seat frame 100. The leg presser 2 is located on the pressure rod 103. The shoulder strap 5 passes through the backrest 21 and the gap 7134 and is then connected to the backrest 101 to secure the bolt 7133. The mounting plate 9 partially surrounds the backrest 21 so that the mounting plate 9 can fit the backrest 21 more closely. The housing 8 is mounted on the mounting plate 9 so that the housing 8 can be more tightly mounted on the backrest 21 through the mounting plate 9, making the overall seat assembly more aesthetically pleasing. The housing 8, the mounting plate 9, and the backrest 21 are fixed together by threaded fasteners.

[0039] The lower part of the seat frame 100 is provided with a first mounting hole 11. Both ends of the first mounting hole 11 are provided with force-enhancing mounting sleeves 12 for extending the lever arm. The seat frame 100 is provided with a mounting groove 13 for installing the force-enhancing mounting sleeve 12 at the position corresponding to the first mounting hole 11. The force-enhancing mounting sleeve 12 includes an insertion end 121 that can be inserted into the mounting groove 13 and an extension end 122 that can extend out of the mounting groove 13 and is used to increase the lever arm. The force-enhancing mounting sleeve 12 is provided with a second mounting hole 123 at the position corresponding to the first mounting hole 11, which passes through the insertion end 121 and the extension end 122 and is connected to the first mounting hole 11. The seat component 1 can extend the lever arm by using the force-enhancing mounting sleeve 12, thereby reducing the thickness of the seat component 1. By installing the force-enhancing mounting sleeve 12 on a thinner seat component 1, the lever arm can be increased, thereby achieving the effect of thickening the support frame 2, thereby reducing the production cost.

[0040] The insertion end 121 and the mounting groove 13 are interference-fitted. The mounting groove 13 is provided with at least one first pin hole 131. A pin 132 is inserted into the first pin hole 131. The surface of the insertion end 121 that is in contact with the bottom of the mounting groove 13 is provided with a second pin hole 133 for the pin 132 to be inserted, thereby restricting the rotation of the force-enhancing mounting sleeve 12, so that the force-enhancing mounting sleeve 12 is not easy to loosen.

[0041] like Figure 9 As shown, in one embodiment, the present invention is installed on a roller coaster, and the seat assembly is installed on the passenger main beam of the roller coaster frame. The restraint device is used to provide passengers with a seat and to protect the safety of passengers while riding the roller coaster.
