Definitions
- the application relates to a buckle device. More particularly, the application relates to a buckle device provided with double protection using remote electronic signals to prevent the buckle device from accidental release.
- the current amusement facilities provide the haptic feedback through a series actions like moving or rotating the seats.
- Seat belts will be installed on the seats to keep the occupants safe.
- the seats will be provided with a fastening structure using plates and latches to fix the occupants on the seats, and prevent accidental occurrences during operation, so that the occupants can safely stick to the seat to feel the haptic feedback produced by the seats' motions.
- Taiwanese Patent No. 1684541 which relates to a buckle device 10 that can provide a latch plate device 11 for insertion.
- the buckle device 10 includes two vertical disks 101, a press body 102, and two electromagnetic rods 103, two first springs 104 arranged between the two vertical disks 101 and the press body 102, two second springs 105 respectively arranged on the two electromagnetic rods 103, and two detectors 106 for detecting the two electromagnetic rods 103.
- the vertical disks 101 can interfere with the latch plate device 11 to fasten the latch plate device 11 in the buckle device 10. After the press body 102 is pressed, the vertical disks 101 can be released from the locked state, so that the vertical disks 101 are pushed by the first springs 104 and meanwhile, the latch plate device 11 is pushed outward.
- the second springs 105 are designed to push the electromagnetic rods 103 into the vertical disks 101, so that the vertical disks 101 can be fastened. Even if the press body 102 is pressed, the vertical disks 101 cannot move. Therefore, the press body 102 can release the locked state occurred between the vertical disks 101 and the latch plate device 11 only when the electromagnetic rods 103 are separated from the vertical disks 101.
- the conventional vertical disk has a complex structure provided with multiple grooves and protrusions for accommodating springs or fastening structures, and cannot be assembled step by step.
- the operators need to depend on the actual situation to install the relevant components in the buckle device, and overcomes the elastic force generated by the spring structure, or the undefined fastening position condition caused by the rotation, so the structure is complex and difficult to assemble.
- the press body can still be pressed. Although the vertical disks are unable to move due to the electromagnetic rods, the press body can be pressed which will cause the occupant uneasiness.
- the vertical disks are set in the middle of the buckle device by rotating shafts. Since the rotating shafts are connected to the two arms of the vertical disks and long, the rotating shafts are easily deformed due to external forces. Furthermore, the vertical disks are directly fastened by the electromagnetic rods, so the pulling force of the latch plate device is obviously insufficient. Besides, there are multiple protrusions on the vertical disks to interfere with other structures and limit the angle of rotation. The multiple protrusions are tiny to wear out. When the vertical disks are worn, accident is easy to happen.

FIG. 1 ,Taiwanese Patent No. 1684541 buckle device 10 that can provide alatch plate device 11 for insertion. Thebuckle device 10 includes twovertical disks 101, apress body 102, and twoelectromagnetic rods 103, twofirst springs 104 arranged between the twovertical disks 101 and thepress body 102, twosecond springs 105 respectively arranged on the twoelectromagnetic rods 103, and twodetectors 106 for detecting the twoelectromagnetic rods 103. - The
vertical disks 101 can interfere with thelatch plate device 11 to fasten thelatch plate device 11 in thebuckle device 10. After thepress body 102 is pressed, thevertical disks 101 can be released from the locked state, so that thevertical disks 101 are pushed by thefirst springs 104 and meanwhile, thelatch plate device 11 is pushed outward. - The
second springs 105 are designed to push theelectromagnetic rods 103 into thevertical disks 101, so that thevertical disks 101 can be fastened. Even if thepress body 102 is pressed, thevertical disks 101 cannot move. Therefore, thepress body 102 can release the locked state occurred between thevertical disks 101 and thelatch plate device 11 only when theelectromagnetic rods 103 are separated from thevertical disks 101. - Although the prior art discloses a buckle device, it still has the following shortcomings in actual use:
- The conventional vertical disk has a complex structure provided with multiple grooves and protrusions for accommodating springs or fastening structures, and cannot be assembled step by step. The operators need to depend on the actual situation to install the relevant components in the buckle device, and overcomes the elastic force generated by the spring structure, or the undefined fastening position condition caused by the rotation, so the structure is complex and difficult to assemble.
- After the conventional electromagnetic rods interfere with the vertical disks, the press body can still be pressed. Although the vertical disks are unable to move due to the electromagnetic rods, the press body can be pressed which will cause the occupant uneasiness.
- The vertical disks are set in the middle of the buckle device by rotating shafts. Since the rotating shafts are connected to the two arms of the vertical disks and long, the rotating shafts are easily deformed due to external forces. Furthermore, the vertical disks are directly fastened by the electromagnetic rods, so the pulling force of the latch plate device is obviously insufficient. Besides, there are multiple protrusions on the vertical disks to interfere with other structures and limit the angle of rotation. The multiple protrusions are tiny to wear out. When the vertical disks are worn, accident is easy to happen.
- Therefore, how to modify the structure to speed up the installation time, and to have a stronger structure to enhance the durability, and furthermore to maintain the proper function of the buckle device is an urgent objective for the relevant technical personnel.

For example, the thickness of thetongue element 41 and the two slider blocks 34 are equal, and the thickness of thetongue element 41 and the slider blocks 34 is less than the distance between thefirst plate 321 and thesecond plate 322. The bottom surface of thefirst plate 321 and the top surface of thesecond plate 322 can clamp thetongue element 41 and the two slider blocks 34. In actual implementation, the distance between thefirst plate 321 and thesecond plate 322, or the thickness of thetongue element 41 and the two slider blocks 34 should be set based on the actual mechanical structure, and should not be construed as limiting the invention. - The
first plate 321 and thesecond plate 322 can clamp the two slider blocks 34, so that the two slider blocks 34 can slide stably in theaccommodating space 31. When thetongue element 41 enters theaccommodating space 31, thefirst plate 321 and thesecond plate 322 can clamp thetongue element 41, so that thetongue element 41 can slide stably in theaccommodating space 31. - When the
tongue element 41 abuts against the two slider blocks 34 and both of them slide in theaccommodating space 31, and the twobolt bodies 51 are alternately pushed against by either thetongue element 41 or the two slider blocks 34. Therefore, the twobolt bodies 51 enter theaccommodating space 31 and extend into the twosecond apertures 36 only when extending into the twotongue openings 42. Otherwise, the twobolt bodies 51 are pushed against by thetongue element 41 and the two slider blocks 34, and cannot enter theaccommodating space 31. - For example, when the
tongue element 41 enters theaccommodating space 31, it abuts against the two slider blocks 34 and is pushed by an external force. The two slider blocks 34 are pushed away from the sides of the twofirst apertures 33 by thetongue element 41, and thetongue element 41 will follow to the sides of the twofirst apertures 33. Then, while thetongue element 41 and the two slider blocks 34 slide in theaccommodating space 31, the twobolt bodies 51 will slide from on thefirst surfaces 39 of the twoslider blocks 34 to thesecond surface 43 of thetongue element 41, so that thetongue element 41 is pushed against the twobolt bodies 51 and prevent the twobolt bodies 51 from entering theaccommodating space 31. When the twotongue openings 42 didn't reach the sides of the twofirst apertures 33 and the external force applied to thetongue element 41 is released, the two slider blocks 34 and thetongue element 41 are pushed by the two firstelastic bodies 35. Therefore, thetongue element 41 is pushed away from the sides of the twofirst apertures 33, and the two slider blocks 34 will follow to the sides of the twofirst apertures 33. Then, while thetongue element 41 and the two slider blocks 34 slide in theaccommodating space 31, the twobolt bodies 51 is pushed against will slide from on thesecond surface 43 of thetongue element 41 to thefirst surfaces 39 of the two slider blocks 34, so that twobolt bodies 51 are pushed against by the twoslider blocks 34 to prevent the twobolt bodies 51 from entering theaccommodating space 31. - It is worth mentioning that the two
first apertures 33 are provided on thefirst plate 321, the twosecond apertures 36 are provided on thesecond plate 322, and the position of the twosecond apertures 36 correspond to the twofirst apertures 33. When thefastening parts 511 of the twobolt bodies 51 enter theaccommodating space 31, thefastening parts 511 will pass through the twotongue openings 42, and further through the twosecond apertures 36. - The
fastening parts 511 of the twobolt bodies 51 respectively pass through the twofirst apertures 33 and the twosecond apertures 36. With the supporting force provided by the twofirst apertures 33 and the twosecond apertures 36, thefastening parts 511 of the twobolt bodies 51 can push against the twotongue openings 42 of thetongue element 41. Therefore, the lateral pulling force of thelatch unit 4 can be effectively resisted, and the structural strength of the buckle device can be enhanced. - Referring to

press body 61 can be shifted between a first position (as shown inFIG. 10 ) and a second position (as shown inFIG. 12 ). When the two slider blocks 34 push against the bottom end of thefastening parts 511 of the twobolt bodies 51, thepress body 61 is pushed to the first position by the thirdelastic body 62 and is spaced apart from the wings of the twobolt bodies 51. When thepress body 61 is located at the first position, thefastening parts 511 of the twobolt bodies 51 can be pushed into theaccommodating space 31. - Referring to
FIG. 10 , when the twobolt bodies 51 enter theaccommodating space 31, thewings 513 of the twobolt bodies 51 abut the twoangled support surface 63 on thepress body 61, and thepress body 61 can be shifted to the second position after being pressed by an external force. When thepress body 61 is shifted from the first position to the second position, theangled support surface 63 of thepress body 61 can support thewings 513 of the twobolt bodies 51, so that thefastening parts 511 can be removed from theaccommodating space 31. - The position of the plurality of limiting
convex bodies 65 is matched with the position of the plurality of stoppingportions 326. The plurality of limitingprotrusions 65 respectively push against the plurality ofstopper portions 326, and the position where thepress body 61 moves in themain unit 3 can be confined. Thepress body 61 and theelectromagnetic fixing portion 325 are pushed against by both the sides of the thirdelastic body 62, and thepress body 61 will be pressed to the left. In the embodiment, there are three sets of the limitingconvex body 65 and thestopper portion 326, which should not be construed as limiting the invention. - Referring to
FIG. 7 , theelectromagnetic unit 7 includes twoelectromagnetic modules 71, twoelectromagnetic rods 72 disposed on the twoelectromagnetic modules 71, and two fourthelastic bodies 73 connected to the twoelectromagnetic rods 72. The twoelectromagnetic rods 72 respectively have amagnetic part 721 arranged in theelectromagnetic module 71 and two blockingparts 722 connected to themagnetic part 721. - Each of the two
electromagnetic modules 71 is an electromagnetic coil structure, and the appearance is like a cylinder with a hole. The twoelectromagnetic modules 71 are respectively disposed in the twoelectromagnetic fixing portions 325. Themagnetic parts 721 of the twoelectromagnetic rods 72 are respectively arranged in the hole of the twoelectromagnetic modules 71, and can be moved by the electromagnetic action of the twoelectromagnetic modules 71 respectively. Since moving the magnetic attractor by the electromagnetic action is a common technique, it will not be detailed hereinafter. - The
electromagnetic rod 72 can be shifted between a third position (as shown inFIG. 10 ) and a fourth position (as shown inFIG. 11 ). When the twoelectromagnetic modules 71 are excited, the twoelectromagnetic rods 72 is located at the third position, and the twoelectromagnetic rods 72 and the twobolt bodies 51 are spaced apart from each other. When theelectromagnetic rods 72 is located at the third position, thepress body 61 can be shifted to the second position (as shown inFIG. 12 ), and the twobolt bodies 51 can be removed from theaccommodating space 31. - When the two
bolt bodies 51 enter theaccommodating space 31 and the twoelectromagnetic modules 71 are not excited, the twoelectromagnetic rods 72 are pushed by the two fourthelastic bodies 73 respectively to the fourth position. The twoelectromagnetic rods 72 respectively interfere with the twobolt bodies 51, so that thebolt bodies 51 won't be pushed away from theaccommodating space 31 by thepress body 61. - Preferably, the two fourth
elastic bodies 73 are respectively disposed between the two blockingparts 722 and theelectromagnetic modules 71, so that the twoelectromagnetic rods 72 can be pushed and shifted to the fourth position. The twoelectromagnetic rods 72 will be shifted to the third position when the twoelectromagnetic modules 71 are excited. - Referring to
FIGs. 3 and8 , thecontrol unit 8 includes twodetection modules 81 disposed in theelectromagnetic fixing portions 325 of thehousing 32 for detecting the position of the twoelectromagnetic rods 72, and acontrol module 82 electrically connected to thedetection modules 81 and theelectromagnetic modules 71, and anoperating module 83 electrically connected to thecontrol module 82. - The
control module 82 is a microcontroller that can run a program to control the amusement facility. The buckle device is arranged on a seat in the amusement facility. The operatingmodule 83 is an operation panel. Preferably, the operatingmodule 83 is a touch screen, which should not be construed as limiting the invention. - In the embodiment, each of the two
detection modules 81 is an infrared detector, which can determine the position of the twoelectromagnetic rods 72 by detecting whether the infrared ray is blocked or not. For example, when the twoelectromagnetic modules 71 are excited, the blockingparts 722 of the twoelectromagnetic rods 72 are far away from thebolt bodies 51. At the same time, themagnetic parts 721 of the twoelectromagnetic rods 72 will move to the right, and the infrared ray emitted from the twodetection modules 81 will be blocked, so that thedetection modules 81 can obtain the information that the twoelectromagnetic rods 72 are located at the third position. When the twoelectromagnetic modules 71 are not excited, the twoelectromagnetic rods 72 are pushed by the two fourthelastic bodies 73 to the left, so that the twoelectromagnetic rods 72 will be far away from the twodetection modules 81, and the infrared ray emitted from the twodetection modules 81 will not be blocked. Therefore, thecontrol module 82 can obtain information that the twoelectromagnetic rods 72 are located at the fourth position. In the embodiment, the twodetection modules 81 are respectively fastened on the twoelectromagnetic fixing parts 325 to detect the position of the twoelectromagnetic rods 72. In actual implementation, this should not be construed as limiting the invention. - The operating
module 83 can display the status of the buckle device, and can also control whether the twoelectromagnetic modules 71 are excited or not. Thecontrol module 82 can be connected to multiple buckle devices and can enable the operatingmodule 83 to display the status of the multiple buckle devices. - In the embodiment, two sets of the
slider block 34, thefastening unit 5, and theelectromagnetic unit 7 are provided. As long as one of the mechanical structures fails, the detection information can be transmitted to thecontrol module 82 by the twodetection modules 81, so that thecontrol module 82 can send out a warning signal through the operatingmodule 83 and stop the operation of the amusement device. In actual implementation, theslider block 34, thefastening unit 5, and theelectromagnetic unit 7 can be provided in one set, and should not be limited to the exemplary embodiment. - Referring to
FIGs. 3 and4 , when the buckle device of the invention is installed, thefastening unit 5 and thepress unit 6 can be installed on thefirst plate 321, and then thefourth plate 324 can be fixed on the twothird plates 323 and theelectromagnetic fixing portion 325. In this way, thefastening unit 5 and thepress unit 6 can be fixed among thefirst plate 321, the twothird plates 323, and thefourth plate 324. Compared with the conventional buckle device with two vertical disks, the buckle device of the invention is relatively simple to install. When the inventor starts to assemble the product, the installation time of the buckle device with the vertical disk is about 3 to 4 hours, while the installation time of the buckle device of the invention is about 1 to 2 hours. The manufacturing time is significantly shortened, and the output can be increased. - Referring to
FIG. 9 , when thetongue element 41 of thelatch unit 4 didn't enter theaccommodating space 31, thefirst surfaces 39 provided on the two slider blocks 34 are pushed by the two firstelastic bodies 35 to the place below the twofirst apertures 33. The positions of the two slider blocks 34 are confined by the two slidingguide bodies 38, so the two slider blocks 34 will not rush out of theaccommodating space 31. At this time, thefirst surfaces 39 provided on the two slider blocks 34 respectively push against the bottoms of thefastening parts 511 of the twobolt bodies 51, so that thefastening parts 511 of the twobolt bodies 51 will not enter theaccommodation space 31. - The
press body 61 is pushed to the first position by the thirdelastic body 62. When thetongue element 41 of thelatch unit 4 didn't entered theaccommodating space 31, even if thepress body 61 is pressed and shifted to the second position, since thefastening parts 511 of thebolt bodies 51 didn't enter theaccommodating space 31, theangled support surface 63 cannot contact thewings 513 of thebolt bodies 51, the buckle device will not perform any operation. - The
control module 82 supplies power to theelectromagnetic modules 71, and theelectromagnetic modules 71 is excite to generate magnetic force externally, so that theelectromagnetic rods 72 can be pushed to the third position. When thetongue element 41 of thelatch unit 4 didn't enter theaccommodating space 31, even if thecontrol module 82 cuts off the power supply to theelectromagnetic modules 71, the two blockingparts 722 of theelectromagnetic modules 71 will be blocked by the twowings 513 of thebolt bodies 51, so theelectromagnetic rod 72 cannot move to the fourth position. At this time, the buckle device will not perform any operation, either. - Referring to
FIG. 10 , when thetongue element 41 of thelatch unit 4 is pushed into theaccommodating space 31, the two slider blocks 34 are pushed by thetongue element 41 and slide to the right. Since the height of thefirst surfaces 39 is the same as the height of thesecond surface 43, the bottom end of thefastening part 511 of thebolt bodies 51 will abut against from thefirst surfaces 39 to thesecond surface 43. The twotongue openings 42 will move to the place below thefastening parts 511 of the twobolt bodies 51. - Since the two
tongue openings 42 are located below thefastening parts 511 of the twobolt bodies 51, the positions of the twotongue openings 42 correspond to the twofirst apertures 33, and thefastening parts 511 of the twobolt bodies 51 are not supported by any object. The twobolt bodies 51 are pushed by the two secondelastic bodies 52 respectively, so that thefastening parts 511 of the twobolt bodies 51 can enter the twotongue openings 42. In other words, thefastening parts 511 of the twobolt bodies 51 enter theaccommodating space 31. At the meantime, thefastening parts 511 of the twobolt bodies 51 interfere with thetongue element 41, so that thetongue element 41 cannot leave theaccommodating space 31. - Referring to
FIG. 11 , thecontrol module 82 decides not to energize the twoelectromagnetic modules 71, and the twoelectromagnetic modules 71 will not generate magnetic force, so the twoelectromagnetic rods 72 are pushed to the left by the two fourthelastic bodies 73 and are shifted to the fourth position. - When the two
electromagnetic rods 72 are located at the fourth position, the two blockingparts 722 of the twoelectromagnetic rods 72 are located above the twowings 513 of the twobolt bodies 51, and the two blockingparts 722 respectively interfere with the twowings 513, so that the twobolt bodies 51 cannot move upward. - Since the two
bolt bodies 51 have interfered with thetongue element 41, and the two blockingparts 722 interfere with the twowings 513 respectively, thepress body 61 cannot be pressed to the second position by external force. Therefore, thetongue element 41 cannot be removed from theaccommodating space 31. In this way, the occupants sitting in the seat can be firmly fixed. In some amusement facilities, the buckle device of the invention can protect the safety of the occupants sitting in the seat. Thecontrol module 82 will start the amusement device, only when both the twodetection modules 81 confirm that the twoelectromagnetic rods 72 enter the fourth position, so that the occupants can be securely fixed to the seat. - If the
control unit 8 loses power, thecontrol module 82 cannot supply power to the twoelectromagnetic modules 71, and the occupants sitting in the seat cannot directly unlock the buckle device. At this time, a release object (not shown) can be used to forcibly unlock the buckle device. The release object is inserted through therelease hole 64 to push thepress body 61 and the twoelectromagnetic rods 72, so that thepress body 61 and the twoelectromagnetic rods 72 will be pushed at the same time. In this way, the twoelectromagnetic rods 72 will be shifted from the fourth position to the third position, and thepress body 61 will be shifted from the first position to the second position. Furthermore, the twobolt bodies 51 will be moved upward to release thetongue element 41. Since the forced unlocking is a common technique, it will not be detailed hereinafter. - Referring to
FIG. 10 , when the occupant wants to leave the seat, thecontrol module 82 supplies power to the twoelectromagnetic modules 71, so that the twoelectromagnetic modules 71 generate magnetic force, and themagnetic portions 721 of the twoelectromagnetic rods 72 receive the magnetic force and move the twoelectromagnetic rods 72 to the third position. In this way, the two blockingparts 722 of the twoelectromagnetic rods 72 leave the place above the twowings 513 of the twobolt bodies 51, and the twoelectromagnetic rods 72 did not interfere with the twobolt bodies 51. - Referring to
FIG. 12 , thepress body 61 is pressed by an external force, so thepress body 61 is shifted from the first position to the second position. At this time, the two angled support surfaces 63 provided on thepress body 61 respectively push against one of thewings 513 of the twobolt bodies 51, and the twobolt bodies 51 are pushed upward. Thefastening parts 511 of the twobolt bodies 51 will leave theaccommodating space 31 from the twotongue openings 42, so that the twobolt bodies 51 won't interfere with thetongue element 41. The two slider blocks 34 are pushed by the firstelastic body 35, and thetongue element 41 is pushed to the left, so that thefirst surface 39 provided on the two slider blocks 34 will be located below the twofirst apertures 33. - Referring to
FIG. 9 , the external force applied on thepress body 61 is released, and thepress body 61 is pressed by the thirdelastic body 62 from the second position to the first position. Thetongue element 41 can be removed from theaccommodating space 31 of themain unit 3 by the occupants. Thebolt bodies 51 are pushed by the secondelastic body 52 to theaccommodating space 31. At this time, thefirst surface 39 of themain unit 3 pushes against the bottom of thefastening part 511 of thebolt bodies 51 and prevent thebolt body 51 from entering theaccommodation space 31. - In the embodiments, in order to simplify the structure, the number of the components like first aperture, slider block, first elastic body, tongue opening, bolt body, second elastic body, second aperture, angled support surface, electromagnetic module, electromagnetic rod, fourth elastic body, detection module and fastening guide body can also be one set, which should not be construed as limiting the invention.
- The following advantages can be obtained by the above description:
- 1. Improving output: The assembling method of the invention is performed by a layer-by-layer stacking arrangement, wherein the setting of the spring is relatively simple, and the structure will not slide. The buckle device can be assembled quickly, and the output of the buckle device can be effectively improved.
- 2. Preventing from be pressed: When the two
electromagnetic rods 72 are located at the fourth position, the two blockingparts 722 of the twoelectromagnetic rods 72 respectively interfere with the twowings 513 of the twobolt bodies 51, and there will be resistance to prevent thepress body 61 from being pressed by an external force. - 3. Enhancing structure: In the invention, the two
bolt bodies 51 move in a straight up and down manner, and the twofastening guide bodies 53 effectively control the twobolt bodies 51 and provide support strength. Furthermore, the twofirst apertures 33 and the twosecond apertures 36 simultaneously push against thefastening part 511 of thebolt body 51. Compared with the conventional rotating structure of the vertical disk, the twobolt bodies 51 can withstand the greater pulling force, so that thelatch unit 4 is not easily separated from theaccommodating space 31. - In conclusion, the
accommodating space 31 having two slider blocks 34 is surrounded and defined by thefirst plate 321, thesecond plate 322, and the twothird plates 323. The two slider blocks 34 can prevent the twobolt bodies 51 from entering theaccommodating space 31. Thetongue element 41 can enter theaccommodating space 31 and push the twoslider blocks 34 to move. Therefore, thefastening parts 511 of the twobolt bodies 51 can extend into the twotongue openings 42, and the twobolt bodies 51 interfere with thetongue element 41 to prevent thetongue element 41 from leaving theaccommodating space 31. - Since the two
first apertures 33 and the twosecond apertures 36 cooperate to push against thefastening parts 511 of the twobolt bodies 51, the supporting force of the twobolt bodies 51 applied to thetongue element 41 can be effectively enhanced, and the structural strength of the buckle device can also be improved. - When the
fastening parts 511 of the twobolt bodies 51 extend into the twotongue openings 42, the twoelectromagnetic rods 72 can be shifted from the third position to the fourth position, and the two blockingparts 722 of the twoelectromagnetic rods 72 can interfere with the twowings 513 of the twobolt bodies 51 respectively. Therefore, thefastening parts 511 of the twobolt bodies 51 can be prevented from leaving the twotongue openings 42 and thepress body 61 can be prevented from being maintained at the first position. - When the two
electromagnetic rods 72 are shifted to the third position, thepress body 61 can be pressed by an external force and shifted from the first position to the second position. The two angled support surfaces 63 can push against thewings 513 of the twobolt bodies 51, and allow thefastening parts 511 of the twobolt bodies 51 to leave the twotongue openings 42, so that thetongue element 41 can be released from the interference caused by the twobolt bodies 51. The two slider blocks 34 and thetongue element 41 are further pushed by the two firstelastic bodies 35, so that thetongue element 41 can leave theaccommodating space 31, and the two slider blocks 34 can be pushed against thefastening part 511 of thebolt body 51. The buckle device can fix thelatch unit 4, so the objective of the invention can be obtained. - The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings.
