In the caster lock device for bags according to the present invention configured as described above, the operation mechanism 11,... The wheels of the casters 5 are pressed by the brake pads 63, 75, 85, 95, 122 of the press stop mechanisms 61,..., The press stop bars 104, 116, etc. via the transmission mechanism 9 that is operated, pulled, pressed, and pushed back. It brakes by making it press-contact, and the traveling travel of the bags 1 is stopped.
In the first and second operation mechanisms 11, 21, when the handle 2 is retracted, the operation bodies 12, 22 are lowered by swinging the swing pulling levers 13, 23 and pulling the transmission mechanism 9. The wheels of the caster 5 are braked by the mechanisms 61,.
In the third and fourth operation mechanisms 31 and 41, the operating bodies 32 and 42 that descend when the handle 2 is retracted directly lowers the vertical movement tow bars 33 and 43, and the lowering operation pulls the transmission mechanism 9. As a result, the wheels of the casters 5 are braked by the pressing stop mechanisms 61.
In the fifth operation mechanism 51, the operating body 52 that descends when the handle 2 is retracted retracts directly without tilting the vertical traction tractor 53 straddling the leg portions of the handle 2, and smoothly descends. The operation pulls the transmission mechanism 9 to brake the wheels of the caster 5 by the pressing stop mechanism 61.

The brake pad 63 disposed on the vehicle is pulled through the transmission mechanism 9 to brake the wheel.
The connecting body 64 is fixed by screwing the wire of the transmission mechanism 9 with the wire connecting portion 65 and screwing (67) the cable body connecting portion 66 inside and outside the insertion portion of the connecting body 64, thereby transmitting the transmission mechanism. The connection between the cable 9 and the tow cord 62 is further strengthened.
In addition, the connecting body 64 is connected to the wire connecting portion 65 screwed to the transmission mechanism 9 by the rope connecting portion 66 so as to be turnable, thereby connecting the towed rope body 62, thereby turning the caster. The wheel is braked without hindering the turning operation of the caster 5 having the configuration.
The traction drive bars 72, 82, 92 and the fifth to seventh press stop mechanisms 101, 111 are inserted into the center positions of the turning surfaces of the caster 5 bases in the second to fourth press stop mechanisms 71, 81, 91. , 121 are inserted into the center position of the turning surface of the base of the caster 5, so that even the caster 5 of the turning caster configuration brakes the wheel regardless of the turning direction. Let me.
In the second pressing stop mechanism 71, the brake pad 75 pulled in the same direction as the pulling direction by the transmission mechanism 9 by the swing lever 73 that is operated by the lever is brought into pressure contact with the inner surface of the wheel to brake the wheel.
The third and fourth press stop mechanisms 81 and 91 are moved via the press stop bars 84 and 94 so as to be pressed in the direction opposite to the pulling direction by the transmission mechanism 9 by the swinging lever levers 83 and 93 that operate the lever. The brake pads 85 and 95 are brought into pressure contact with the outer surface of the wheel from a position almost directly above or slightly obliquely above to brake the wheel.
In the fifth press stop mechanism 101, a swinging insulator that operates by connecting the wire of the transmission mechanism 9 pulled for operation transmission and the press stop bar 104 that presses against the outer surface of the wheel of the caster 5 to operate the lever. The lever 103 converts the traction by the transmission mechanism 9 into the pressing of the pressing stop bar 104 against the wheel, presses against the wheel, and brakes the wheel. Further, since the swing lever lever 103 is disposed in the working chamber 8D inside the bags 1, the lever operation is ensured. In the sixth and seventh press stop mechanisms 111 and 121, the slide drive surface 114 of the press drive body 113 that slides back and forth through the slide cable body 112 by towing the transmission mechanism 9 swings the driven swing lever 115. This swinging presses and presses the pressing stop bar 116 and the brake pad 122 against the outer surface of the wheel of the caster 5 to brake the wheel.

  Since the present invention is configured as described above, in a bag 1 such as a suitcase that can be moved and moved by a pull-out telescopic handle 2 by rolling of a wheel of a caster 5, the handle 2 The rolling of the wheel can be braked and stopped automatically via the operating body 12,... Of the caster lock device 10 by the retracting and storing operation, and the moving traveling by the wheel can be performed along with the extension of the pulling out of the handle 2.

  That is, in this device, the caster lock device 10 corresponds to the expansion and contraction of the handle 2 and is operated in conjunction with the retracting and retracting operation, and the operation by the operation mechanism 11,. A pressing stop mechanism 61 that prevents rolling of the wheel by a stopping force that presses and stops against the outer surface or inner surface of the wheel of the caster 5 by being transmitted through the transmission mechanism 9 including a wire that is pressed and pushed back. It is because it comprises. As a result, the wheels of the caster 5 can be braked according to the pulling out and storing of the handle 2.

  Further, since the transmission mechanism 9 includes a wire that is pulled, pressed, or pushed back, the bags 1 that are provided with the casters 5 from the upper position of the bags 1 that are provided with the handle 2 even along the outer wall surface of the bags 1. Even if a plurality of casters 5 are provided at any part of the bottom position so as to reach the bottom position, the casters 5 can be arranged so as to reach the respective casters 5, and the operation of the operation mechanisms 11,. It can be reliably transmitted to the mechanisms 61,.

  The operating mechanisms 11,... Are moved up and down together with the handle 2 by operating bodies 12, 22, 32, 42, 52 provided on the handle 2 that moves up and down to be pulled out and stored. 12 and 22 swing the swinging traction levers 13 and 23, or the operating bodies 32, 42 and 52 lower the vertical movement traction bars 33 and 43 and the vertical movement traction board 53, thereby via the transmission mechanism 9. The pressing stop mechanism 61 can be reliably operated.

  The pressing stop mechanism 61,... Presses the inner side surface or the outer side surface of the wheel rolling on the caster 5, or presses and presses the brake pads 63, 75, 85, 95, 122, or presses the stop bars 104, 116. Since the rolling is prevented, the wheel can be reliably braked.

  Further, in these pressing stop mechanisms 61,..., The transmission mechanism 9 and the traction cable body 62, the traction drive bars 72, 82, 92, and 102, the slide cable body 112, and the like are linked by linking bodies 64, 143, and the like. Therefore, the structure of the transmission mechanism 9 and the structure of the pressing stop mechanisms 61,... Can be separately configured and incorporated in the bags 1 so that the caster lock device 10 can be assembled in various combinations. .

  The restoring portions 68, 76, 86, 96, 117, etc. in the pressing stop mechanism 61,... Are applied to the wheels by the pulling / extending operation of the handle 2 when the bags 1 are moved after braking of the wheels of the casters 5. Thus, the braking action of the brake pads 63, 75, 85, 95, 122 and the pressing stop bars 104, 116 that are pressed and stopped can be released, and the wheels can roll smoothly.

  Since the traction cable body 62 of the first pressing stop mechanism 61 is formed to be bendable, even if the caster 5 has a turning caster configuration, it follows the turning movement, regardless of the rolling direction of the wheels. The brake pad 63 can be pressed against the wheel from the inner surface of the wheel, and braking is performed reliably.

  The traction drive bars 72, 82, 92, the fifth to seventh press stop mechanisms 101, 111, are inserted through the center positions of the turning surfaces of the caster 5 bases in the second to fourth press stop mechanisms 71, 81, 91. Since the press stop bars 104 and 116 in 121 are provided so as to penetrate the caster 5 base at the center position of the swivel surface in the caster 5 base, for example, it is a swivel caster configuration. Thus, braking can be reliably performed without hindering the braking action on the wheels.

  Since the press stop bars 84, 94, 104, 116 in the third to sixth press stop mechanisms 81, 91, 101, 111 are pressed against and pressed against the outer surface of the wheel of the caster 5, the wheels are braked. Coupled with the fact that the traction drive bars 82 and 92 for operating the press stop bars 84, 94, 104, and 116 or the press stop bars 104 and 116 themselves are arranged at the turning center position of the caster 5 that turns, This is suitable for braking a wheel of a wheel type single caster, and the lower end of the press stop bars 84, 94, 104, 116 is slightly press-fitted to the wheel, so that braking can be reliably performed.

  Further, the swing lever levers 73, 83, 93, 103 in the second to fifth press stop mechanisms 71, 81, 91, 101 can appropriately double the traction operating force by the operation mechanisms 11,. It is possible to strengthen the pressure contact and pressure stop action of the caster 5 to the wheel.

  In the sixth and seventh press stop mechanisms 111 and 121, the slide drive surface 114 of the press drive body 113 moved back and forth by the slide cable body 112 slid back and forth is driven and oscillated by the press action of the slide drive surface 114. Since the lever 115 is swung and the press stop bar 116 is lowered by the swing of the driven swing lever 115 to be pressed and pressed against the wheel, the transmission path to the press stop mechanisms 111 and 121 by the transmission mechanism 9 is defined as bags. 1 can also be along the lateral direction in FIG.
