A hollow shaft portion 7 is provided, and a press stop bar 35 in a press stop mechanism 30 described later is inserted into the hollow shaft portion 7 (see FIG. 6). By doing so, it is possible to configure a transmission structure for pressure contact / pressure stop and release via a caster support 4 via a transmission mechanism 29 described later with respect to the wheels in the caster 2. Of course, the mounting structure of the caster 2 is not limited to the illustrated example.

  A caster lock device 20 is provided that corresponds to an expansion / contraction operation for pulling out / storing the handle 10, that is, when the handle 10 is retracted, the rolling of the caster 2 itself is temporarily stopped. Yes. The caster lock device 20 is adapted to extend and contract the handle 10, and the operation mechanism 21 having a lock switch 22 that is operated in conjunction with the retracted storage and the operation of the operation mechanism 21 by the lock switch 22 are pulled. Stopping force is applied to the outer surface or inner surface of the wheel of the caster 2 by being transmitted through the transmission mechanism 29 having a wire, and the wheel is prevented from rolling and braked. And a pressing stop mechanism 30 for releasing the braking action, and the lock switch 22 can operate the transmission mechanism 29 by being pressed by further pushing of the handle 10 stored in the handle storage portion 9 of the bags 1. .

  Note that the wire of the transmission mechanism 29 is, for example, the outside of the bag 1 between the lock switch 22 portion of the operation mechanism 21 to which the upper end of the wire is connected and the press stop mechanism 30 that locks the caster 2. It is slidably accommodated in, for example, a sheath tube constituting the transmission path so as to slide along a transmission path formed along the inner wall surface.

  The handle 10 is fixed to the back of the bag 1 along the vertical direction by the upper and lower fixing arms 14 so that the handle 10 of the bag 1 The leg portion 11 is inserted so as to be slidable so that it can be pulled out upward and can be pushed in and stored. The upper end opening of the handle storage cylinder 13 is located on the bottom surface of the handle storage section 9 formed by being recessed in the upper part of the bags 1, and the handle 10 itself is slid along the handle storage cylinder 13. Are provided with a plurality of locking mechanisms 15 that are temporarily fixed at appropriate positions.

  This locking mechanism 15 is elastically locked to a hole-shaped locking portion 16 formed at a predetermined position of the handle storage cylinder 13 at the lower end of the leg portion 11 of the hollow handle 10 as shown in the figure. The click body 17 is slidably disposed so that the click body 17 is freed via the transmission means 19 by pressing the release button 18 disposed on the grip portion 12 of the handle 10 so that the handle 10 can be slid. When the click body 17 is locked to the locking portions 16A,..., The release button 18 is protruded and returned.

  Then, the locking portions 16A,... Are, as shown in FIG. 1, a plurality of positions (16A) that are locked in a temporarily fixed shape corresponding to the selected position of the pull-out length of the handle 10 itself, and also shown in FIG. In order to lock the caster 2 at the position (16B) where the handle 10 is stored in the handle storage portion 9 as shown in FIG. 3, the lock switch 22 is further pushed down to stop it. At the position (16C), the handle 10 is stopped and maintained. In the locking portion (16B) corresponding to the storage position of the handle 10, the upper edge of the grip portion 12 of the handle 10 is substantially the same height as the upper edge position of the handle storage portion 13, and at least the handle storage portion 13 is used. Compared to the upper edge position, the upper edge position does not protrude greatly.

  The handle 10 shown in the figure has an inverted U-shape in which the leg portions 11 are arranged in pairs on the left and right sides and the upper ends of the leg portions 11 are connected by the grip portion 12, but this is a single leg shape. Even when the leg portion 11 is configured to be extendable and contractable between the small-diameter portion and the large-diameter portion, the locking mechanism 15 can be similarly configured.

  The operation mechanism 21 shown in the figure includes a push-in operation portion 23 provided on the grip portion 12 at the top of the handle 10 so as to protrude from the grip portion 12 surface, for example, on one of the front and rear sides of the grip portion 12, and a press stop. A transmission mechanism 29 for transmitting to the mechanism 30, that is, a lock switch 22 that is connected to a wire and slides up and down, and an up and down slide guide 24 that slides the lock switch 22 up and down. The push-in operation unit 23 can also be provided on the leg portion 11 of the handle 10.

  As shown in the drawing, the lock switch 22 itself has left and right widths so as to be bridged between the handle storage cylinders 13 arranged on the left and right sides, and includes a protrusion that protrudes downward at the center. The cylindrical upper and lower slide guides 24 formed integrally with the left and right side edges are slidably enclosed in the handle storage cylinder 13, for example, outside thereof. By fitting in such a manner, the sliding guide is smoothly performed in the vertical direction. At the center of the lock switch 22, a pair of wires of the transmission mechanism 29 are connected to the wire end in a state where the wires are extended downward from the upper end of the transmission path so that the wires are connected from the upper side of the lock switch 22. For example, a wire connecting portion 25 is provided for screw connection.

  In the drawing, the lower end edge of the push-in operation unit 23 comes into contact with the upper end edge of the slide guide 24, and the downward push-in of the push-in operation unit 23 pushes down the slide guide 24 so that the lock switch 22 itself slides downward. It is. The upper end portion of the slide guide 24 slides up and down at a position slightly protruding from the bottom surface of the handle storage portion 9. When the handle 10 is temporarily stopped in the state where it is stored in the handle storage portion 9, even if it is in contact with the lower edge of the push-in operation portion 23, it does not slide downward in this state, and the handle 10 further When pushed, the slide guide 24 is slid downward to push down the lock switch 22. In this manner, the lock switch 22 slides downward by further pushing the handle 10 in the handle housing portion 9 and pulls the transmission mechanism 29 to operate the pressing stop mechanism 30.

  The lock switch 22 is unlocked when the handle 10 is pulled up. At this time, the lock switch 22 returns to the original position by the return force of the return portion 36 in the press stop mechanism 30 described later, and again. Wait for the lock operation.

  In the illustrated example, the pressing stop mechanism 30 is provided in an operating chamber 31 that is partitioned in the operating mechanism linking body 5 that is disposed in contact with the inner surface of the caster mounting portion 3 that is the mounting position of the caster 2. The traction drive bar 32 that moves up and down and is linked to the end of the transmission mechanism 29 is pivotally supported in the arrangement chamber 33 that is also defined in the operating mechanism linkage 5, and the traction drive bar 32 is pivotally supported at the tip. The swing lever lever 34 is pivotally supported by the swing lever lever 34 so as to be movable up and down. A pressing stop bar 35 that presses against the outer surface of the wheel 2 and a restoring portion 36 that elastically biases the traction drive bar 32 so as to separate the pressing stop bar 35 from the outer surface of the wheel (see FIG. (See FIG. 6). The pressing stop bar 35 is inserted through the bottom wall of the arrangement chamber 33 of the transmission mechanism connecting portion 5, and the center position of the swiveling surface in the horizontal plane at the base portion of the caster 2 that is pivotally supported by the caster support 4. It is arranged by being inserted into the hollow shaft portion 7 provided in the upper and lower sides of the caster 2 so as to be smoothly operated to press and release against the outer surface of the wheel of the caster 2 by the vertical movement in the arrangement chamber 33. It is.

  The working chamber 31 of the transmission mechanism linking body 5 in the press stop mechanism 30 is formed adjacent to the side portion of the arrangement chamber 33 independently or integrally, and is a partition that partitions the upper and lower portions. 37. As shown in the figure, when the working chamber 31 is formed in a continuous and integrated manner with the distribution chamber 33, the swing lever lever 34 is pivotally supported in the distribution chamber 33 by being positioned on the working chamber 31 side. Although not shown in the drawings, when the working chamber 31 is partitioned and formed independently of the placement chamber 33, the swing lever lever 34 is positioned in the placement chamber 33 and pivotally supported.

  The swing lever lever 34 is pivotally supported in the arrangement chamber 33 at substantially the center position thereof, and a traction drive bar 32 is pivotally supported at one end side and a pressing stop bar 35 is pivotally supported at the other end side. The rising (upward movement) of the drive bar 32 is converted into the lowering (downward movement) of the pressing stop bar 35, and the lower end of the pressing stop bar 35 is pressed against the wheel. Further, when it is desired to increase the pressure contact force, it can be dealt with by shifting the pivot support position of the swing lever lever 34 toward the traction drive bar 32 side.

  The traction drive bar 32 is connected to the wire of the transmission mechanism 29 in the upper chamber portion of the working chamber 31, and the restoring portion 36 includes a lower surface of the partition wall 37 in the working chamber 31 and a working chamber in the traction driving bar 32. A coil spring which is elastically biased in an extending tendency is contracted between the spring lock 38 which is fixedly screwed to the upper portion of the lower chamber portion 31 of the lower chamber portion. Further, the pressing stop bar 35 is inserted into a vertical movement guide 39 provided on the caster support 4 itself so as to smoothly guide the vertical movement thereof.

  Although not shown, a brake pad that is in pressure contact with the outer surface of the wheel of the caster 2 can be connected to the lower end of the press stop bar 35, so that the press stop action can be taken into consideration.

  The pressing stop mechanism 30 in the illustrated example is suitable for pressing against the outer surface of the wheel in the caster 2 having a single caster structure, but if the caster 2 has a double caster structure having a double caster structure, the transmission mechanism 29 is used. It is also possible to adopt a pad configuration in which traction by pressure is directly actuated or indirectly actuated by lever action or the like so as to press and stop against the inner surface of the wheel. In any case, the traction action by the transmission mechanism 29 may be either directly or indirectly, and the wheel of the caster 2 may be braked by pressure contact / stopping by a link mechanism, a lever mechanism, a slide mechanism, or the like. Is not particularly limited.

  The caster 2 itself in the embodiment described above may be a single caster having a single wheel structure or a double caster having a twin-wheel structure. Moreover, both the fixed caster in which the rolling direction is fixed and the swivel caster in which the rolling direction is free are arbitrary, and the press stop mechanism 30 corresponding to these casters. Thus, the rolling of the caster 2 is stopped and braked.

  7 to 10 show another example of the operation mechanism 21. That is, the left and right pushing operation parts 23 provided in a projecting manner on the leg portion 11 of the handle 10 and the transmission mechanism 29 for transmitting to the pressing stop mechanism 30, that is, the wire is connected, and the left and right handles are slid up and down. The left and right lever levers that are connected to each other between the wire connecting body 26 disposed between the storage cylinders 13 and the slide body 27 and the wire connecting body 26 that are slid down by the push-in operation unit 23 and swing by lever operation. 28, and the lock switch 22 is configured by the wire coupling body 26, the slide body 27, and the lever lever 28.

  In this operation mechanism 21, the push-in operation portion 23 is formed in a flange shape on the upper portion of the leg portion 11 of the handle 10, and the slide body 27 pushed by the push-in operation portion 23 is temporarily stored in the handle storage portion 9. Before the handle 10 is pushed in, the handle 10 is positioned so as to slightly protrude upward from the bottom of the handle storage portion 9. The slide body 27 is arranged along the handle storage cylinder 13, and when the handle 10 once stored in the handle storage portion 9 is further pushed, the push lever 23 pushes down the slide body 27, so that the lever lever By pulling up the wire coupling body 26 by 28, the wire as the transmission mechanism 29 is pulled. To pull the wire, the press stop mechanism 30 is actuated to lock the caster 2, and the handle 10 can be pulled out above the bags 1 to return the wire to release the lock and roll the caster 2. Let me. The push-in operation part 23 can also be provided on the grip part 12 of the handle 10.

  The upper end surface of the slide body 27 is pressed against and brought into contact with the bottom surface of the push-in operation portion 23. Both the guide portions 27A formed on the outer side surface of the handle storage cylinder 13 along the vertical direction. A slide portion 27B that is arranged on the side and slides is provided in the lower portion, and a pin-like connection portion 27C that is connected to the rear end of the lever lever 28 is provided in the upper portion. For example, the lever lever 28 is pivotally supported by a swing fulcrum set at a position below the handle housing portion 9 so as to be swingable, and the front end of the lever lever 28 is pivotally supported by the wire coupling body 26. When the rear end of the lever 28 is pushed down, the wire coupling body 26 is pulled upward, and the wire of the transmission mechanism 29 is pulled.

  In this operation mechanism 21, even if the handle 10 is once stored in the handle storage portion 9 at the position where the upper surface of the grip portion 12 of the handle 10 is substantially the same as the upper surface of the bag 1 as shown in FIG. The pushing operation unit 23 does not push the slide body 27 and is in a free state in which the caster 2 can roll. Then, as shown in FIG. 10, when the handle 10 is further pushed into the handle housing portion 9, the slide body 27 is pushed down, the wire connecting body 26 is pulled up by the lever lever 28, the wire of the transmission mechanism 29 is pulled, and the pressing is stopped. The mechanism 30 locks the caster 2.

  Next, an example of the operation will be described. When the bags 1 are moved, the caster 2 may be rolled in the traveling direction by the handle 10 pulled out from the handle storage portion 9 (see FIG. 1), and conversely stopped. In order to prevent the movement, the handle 10 is pushed once into the handle housing 9 and the handle 12 is pushed in one more stage (see FIG. 3). The caster 2 is locked by pulling down and pulling the transmission mechanism 29 to operate the pressing stop mechanism 30. Further, the handle 10 is lifted slightly without being pushed down to the lowest position in the handle storage portion 9, that is, the grip portion 12 of the handle 10 is set at the upper edge position of the handle storage portion 9 (FIG. 2), the bags 1 can be moved while the handle 10 is stored.

  In the movable state of the bags 1 from which the handle 10 has been pulled out, the caster 2 can be locked by pushing the handle 10 into the lowermost position in the handle storage portion 9 at once, and the movable state can be stopped. On the contrary, it is also possible to make it movable by pulling out the handle 10 at the lowest position in the locked state at once.

  Thus, the movement and stop of the bags 1 can be freely selected by operations such as pulling out the handle 10, storing it in the handle storage portion 13, and pushing it down further, etc. The adjustment of the pull-out length can be performed by selecting a temporary fixing position with respect to the above-described locking portion (16A).
