A plurality of locking hook portions are provided on the base frame 10. Each locking hook portion is provided at a position corresponding to the locking hole in a state where the bag main body 30 is placed on the mounting table 16, and can be inserted into the locking hole 3. Here, a pair of first locking hooks 11 that can be inserted into the first locking holes 31 and a pair of second locking hooks 12 that can be inserted into the second locking holes 32 are provided as the locking hook portions. Yes. The 1st latching hook 11 and the 2nd latching hook 12 are spaced apart and provided in the extension direction of the standing part, ie, a perpendicular direction. In FIG.1 and FIG.2, the 1st latching hook 11 is arrange | positioned above the standing part, and the 2nd latching hook 12 is arrange | positioned below, respectively. Similarly, the first locking hole 31 into which the first locking hook 11 is inserted is provided above the back surface of the heel body 30, and the second locking hole 32 into which the second locking hook 12 is inserted is the heel body 30. It is provided under the back surface of.
(First locking hook 11)

  In the first embodiment, the first locking hook 11 is fixed to the standing portion 9. On the other hand, the second locking hook 12 is provided on the slide portion 20. That is, the first locking hook 11 is fixed, and the second locking hook 12 is slidable, thereby facilitating the operation of connecting and separating the bag body 30 to the base frame 10. Specifically, the first locking hooks 11 are respectively inserted into the first locking holes 31 and the scissors main body 30 is mounted on the mounting table 16, and the second locking hook 12 is set with the slide portion 20 as the release position. Is inserted into the second locking hole 32, and the slide portion 20 is slid from the release position to the lock position along the erected portion to connect the heel body 30 to the base frame 10. Thus, the slide part 20 is provided in the cylinder part 19 which accommodates the expansion-contraction rod 18, and the connection structure with the collar main body 30 is implement | achieved.

  The pair of locking hooks of the first locking hook 11 is fixed at a predetermined position of the cylindrical portion 19. Preferably, as shown in FIG. 3, the distance from the mounting surface to the first locking hole 31 in the state where the bag main body 30 is mounted on the mounting table 16, and the distance from the mounting surface to the first locking hook 11. The first locking hook 11 is positioned on the cylindrical portion 19 so that the distances are substantially the same.

  Moreover, as shown in FIG. 1, FIG. 2, etc., you may provide the 1st connection rod 24 which connects a pair of 1st latching hooks 11 mutually. Thereby, the base frame 10 can be reinforced.

  Each locking hook portion has a size and a shape that can be inserted into the opening of the locking hole 3. That is, a locking hook portion is formed that is substantially the same as or slightly smaller than the opening of the locking hole 3. In this example, the locking hook is bent in a substantially L shape in cross-sectional view. At this time, as shown in FIG. 4A and the like, the tip of the locking hook has a claw shape, so that the tip of the locking hook becomes thin and can be easily inserted into the locking hole. In particular, in the case of a patch-type locking hook as shown in FIG. 2, the flat part is almost flat at the time of flatness and almost no opening is formed. By using such a locking hook with a thin spatula at the tip, , Can be easily inserted into the locking hook.

  In addition, since the locking hook has a tapered section, the locking hook becomes thicker and stronger as it is inserted into the locking hole, and the locking hook becomes thicker at the thickened portion. And the inner surface of the locking hole can be brought into close contact with each other, and the locking hook and the locking hole can be engaged by frictional resistance at this interface.

Further, the locking hook is made of a hard material such as metal or plastic so that sufficient strength can be obtained.
(Second locking hook 12)

  The second locking hook 12 is a member configured to be inserted into the opening of the second locking hole 32 of the heel body 30 to lock the heel body 30. As with the first locking hook 11, the locking hook of the second locking hook 12 is substantially L-shaped in vertical sectional view. The front end of the locking hook extends along the telescopic rod 18. The second locking hooks 12 are each fixed at a predetermined position on the slide portion 20. With this configuration, the position of the second locking hook 12 can be adjusted by sliding the slide portion 20.

In Example 1 shown in FIG. 4A and the like, the first locking hook 11 is disposed above the second locking hook 12. Furthermore, the tip of the first locking hook 11 is bent upward. On the other hand, the tip of the second locking hook 12 is bent downward. In addition, the first locking hook 11 is fixed to the cylindrical portion 19 and, in other words, does not move in the vertical direction. On the other hand, the second locking hook 12 is provided on the slide portion 20 and moves up and down along the cylindrical portion 19. By doing in this way, when a user attaches / detaches the bag main body 30 to / from the base frame 10, as shown in FIG. 4A, the operation of locking the first locking hole 31 to the upper first locking hook 11 is facilitated. Yes. In other words, it is possible to reduce the burden on the user as a configuration in which the user hooks the locking hook into the locking hole on the upper side that is relatively easy to work without bending the user to an unreasonable posture.
(Procedure for connecting the bag body 30 to the base frame 10)

  Here, based on FIG. 4A-FIG. 4C, the procedure which mounts the bag main body 30 to the base frame 10 is demonstrated. First, as described above, as shown in FIG. 4A, the first locking hook 11 is locked in the first locking hole 31 on the back surface side of the bag main body 30. At this time, as shown in FIG. 4B, the bag main body 30 is in a state where the first locking hook 11 is locked in the first locking hole 31 and the bottom surface thereof is in contact with the platform 16. It is preferable to design the positions of the hole 31 and the first locking hook 11. Thereby, in the state which set the heel main body 30 to the base frame 10, the situation where the weight of the heel main body 30 concentrates on a connection mechanism can be avoided, and the reliability of a connection mechanism can be improved.

The slide portion 20 provided with the second locking hook 12 is positioned at the release position, that is, the upper side. At this time, a mechanism may be provided so that the slide portion is held at the release position, that is, does not naturally descend to the lock position. For example, a stopper mechanism may be provided to increase the coefficient of friction between the inner surface of the slide portion and the outer surface of the tube portion, or to hold the slide portion at the release position.
Next, as shown in FIG. 4B, with the first locking hook 11 locked in the first locking hole 31, the slide part 20 is lowered and moved from the release position to the locked position, The second locking hook 12 is locked to 32. Thus, the reliability of the locked state can be improved by matching the operation of lowering the slide portion 20 with the movement from the release position to the lock position. That is, when the heel body 30 is mounted on the base frame 10 and used, even if the slide portion 20 is lowered by its own weight, the connection is strengthened, so that the heel body 30 may be unintentionally detached. Can be reduced. Preferably, as shown in FIG. 4C, when the slide portion 20 is in the locked position, the slide portion 20 is in the lowest position where it abuts against the tubular body 16b and does not fall any further. Thereby, it can avoid that the main body 30 remove | deviates by the fall which the slide part 20 does not intend. Even when the bag body 30 is mounted, the user can move the slide unit 20 to the lowest position, for example, by pressing the slide unit 20 down to the full position, so that the locked state can be obtained. In addition, it is possible to easily switch from the release position to the lock position. In particular, even when used by an elderly person, it is easy for anyone to handle as an easy-to-understand procedure by omitting complicated operations.

  The work of removing the bag body 30 from the base frame 10 can be easily performed in the same manner by performing the reverse procedure to the above, that is, in the order of FIGS. 4C, 4B, and 4A.

  As described above, the extension of the distal end of the first locking hook 11 bent in an L shape and the distal end of the locking hook of the second locking hook 12 are reversed, so that the heel 100 with casters is provided. It is possible to effectively prevent the case 30 from being detached from the base frame 10 during the movement of the frame. That is, as shown in the exploded perspective view of FIG. 5, if the L-shapes of the locking hooks 513 provided at the four locations are configured to bend in the same direction, for example, upward, only the heel body 530 is upward when used. When force is applied, there is a possibility that the locking hooks 513 come out from the four locking holes 533 at once and are detached from the base frame 510. On the other hand, in the first embodiment, as shown in FIG. 2 and the like, the hooks bent in the opposite directions in the vertical direction are arranged apart from each other in the vertical direction, so that the bag body 30 or the base frame 10 is arranged. Even if a stress is applied in the vertical direction to any one of these, the bag main body 30 does not come off the base frame 10.

Further, when the four hooks 513 are fixed in the same posture as shown in FIG. 5, when the hook body 530 is attached to the base frame 510, the four hooks 513 are moved to the four hook holes. It is necessary to perform alignment so as to match all of 533, and this alignment work becomes troublesome. Depending on the user, for example, when a person whose hand is not dexterous, such as an elderly person or a physically handicapped person, such alignment work can be difficult. On the other hand, in the configuration according to the first embodiment, it is sufficient to align the two locking hooks with the two locking holes, so that it is much easier than the configuration in which the four positions are aligned at the same time. Can be aligned. Then, after the first locking hook 11 is locked in the first locking hole 31, it is sufficient to lock the remaining two second locking hooks 12 in the second locking holes 32. At this time, since the positioning between the first locking hook 11 and the second locking hole 32 is completed, the positioning is almost completed. By setting the contact state, the second locking hook 12 and the second locking hole 32 are positioned almost automatically. After that, the sliding portion 20 is simply slid downward in this state, so that the second locking hook 12 and the second locking hole 32 are positioned. The stop hook 12 can be locked in the second locking hole 32. As described above, since the troublesome alignment work when attaching the bag body to the base frame can be greatly simplified, a user-friendly bag with casters that is extremely easy to handle is realized.
(Example 2)

  In the first embodiment, the configuration in which the pair of slide portions are connected to each other by the connecting rod so that they are interlocked and the lock position and the release position can be switched is shown. However, the present invention is not limited to this configuration, and the slide It is also possible to make the parts independently movable. Such an example is shown in FIG. In the cage 200 with casters according to the second embodiment, the pair of slide portions 220 are slidable along the cylindrical portion 219, and each second locking hook 212 is individually locked in the second locking hole 232. To do. The caster-equipped cage 200 is similar to FIG. 2 and the like. The base frame 210 has a substantially rectangular plate-shaped platform 216, casters 215 provided at the four corners of the lower surface, and a standing portion extended vertically from the upper surface. Is provided. The standing portion is extended from the back corner to a vertical posture and has a pair of cylindrical portions 219 whose upper ends are open ends, and a pair of telescopic rods 218 inserted so as to be freely drawable from the open ends of the cylindrical portions 219, A grip 217 that connects the upper ends of the telescopic rods 218 is provided.

  In the configuration in which the pair of slide portions are connected to each other by the connecting rod, it is necessary to provide these slide portions at a substantially horizontal position in order to keep the connecting rod parallel to the mounting base. In other words, the height at which the slide portion is provided is limited to different heights between the left and right tube portions. However, with the configuration of the above-described second embodiment, each slide portion 220 can be operated independently. The second locking holes 232 need not be provided at the same height, and can be provided at an arbitrary height.

In addition, in this configuration, the two slide portions 220 cannot be locked at the same time, and it takes time to attach and detach the bag main body 230. However, each locking operation is performed individually. With the stop hook 211 inserted into the first locking hole 231, the second locking hook 212 can be securely inserted into the second locking hole 232 and the locking operation can be performed. In addition, since no connecting rod is required, the number of parts can be reduced to reduce the weight and cost.
(Example 3)

  In the above-mentioned cage with a caster, the tip of the first locking hook arranged at the upper side is bent in an L shape in a vertical sectional view, and the tip of the second locking hook arranged at the lower side is bent downward. Although an example is shown, the present invention is not limited to this configuration. For example, the front end of the locking hook disposed above may be bent downward, and the front end of the locking hook disposed below may be bent upward. Such an example will be described as a third embodiment based on the side views of FIGS. 7A to 7C. The caster-equipped scissors 300 according to the third embodiment also includes a first locking hook 311 with an L-shaped leading end facing upward and a second locking hook 312 facing downward, spaced apart in the vertical direction. . However, in Example 3, the first locking hook 311 is disposed below the standing portion, and the second locking hook 312 is disposed above the standing portion. Similarly, the first locking hook 311 disposed below is fixed to the tube portion 319, while the second locking hook 312 disposed above is fixed to the slide portion 320 and the slide portion 320 is fixed to the tube portion 319. It is slidable along the extending direction. The slide portion 320 also has an upper position as a release position and a lower position as a lock position. Preferably, as shown in FIG. 7C and the like, the cylindrical portion 319 is provided with a stopper 321 so as to prevent the slide portion 320 from being lowered at the locked position.

  The bag body 330 can use the same configuration as that of the first embodiment. Here, for convenience, a first locking hole 331 for inserting the first locking hook 311 is provided below, and a second locking hole 332 for inserting the second locking hook 312 is provided above. However, like the first embodiment, the first locking hole 331 and the second locking hole 332 have the same structure. In particular, since the patch having a non-adhesive middle as a locking hole can be inserted from either the upper side or the lower side, it can be configured in common with the first and second embodiments.

  In order to connect the caster-equipped scissors 300 having this structure to the base frame 310, first, as shown in FIG. 7A, the scissors main body 330 was placed on the upper surface of the platform 316 and provided on the lower back side of the scissors main body 330. The first locking hole 331 is locked to the first locking hook 311 fixed below the base frame 310. At this time, the slide part 320 is set to the upper release position.

  Next, as shown in FIG. 7B, with the first locking hook 311 locked in the first locking hole 331, the heel body 330 is moved so that the second locking hole 332 is close to the second locking hook 312. As the upright posture, the slide part 320 is lowered from the release position to the lock position. By this operation, the second locking hook 312 is inserted into the second locking hole 332 and is fixed by the connecting mechanism in a state in which the main body 330 is mounted on the mounting table 316 as shown in FIG. 7C. . Note that, when separating the bag main body 330 from the base frame 310, the reverse procedure is performed.

  As described above, also in the configuration of the third embodiment, the second locking hook 312 is slidable, and the heel body 330 and the base frame 310 can be easily attached and detached. Also in the third embodiment, the folding direction of the locking hooks is reversed between the first locking hook 311 and the second locking hook 312. Even if vertical stress is applied to the frame 310 alone, it is possible to avoid the situation where the heel body 330 is detached from the base frame 310.

  In the above example, the locking hook is formed of a hard member, and the locking hole for inserting the locking hook is formed of a flexible member. However, the present invention does not limit the locking hook and the locking hole to this configuration. For example, the locking hole may be made of a hard member. By configuring the locking hole with a hard member, the strength of the locking hole can be increased, and the mechanical strength of the mechanism connected to the locking hook can be increased. In addition, since the locking hole is always formed, the operation of inserting the locking hook is further facilitated. Furthermore, it is possible to add a fitting structure for fitting the hooks in a state where the hooks are inserted into the locking holes. Such an example is shown in the exploded perspective view of FIG. 8 and the enlarged exploded perspective view of FIG. The locking holes 434 shown in these drawings are formed in a box shape penetrating a rectangular opening, and are formed in a size that allows the locking piece 414 formed at the tip of the locking hook 413 to be inserted. The locking piece 414 of the locking hook 413 is further formed with a claw-like projection 414b. With the locking piece 414 inserted from the inlet side of the locking hole 434, the tip of the locking piece 414 protrudes from the outlet side, and the protrusion 414b of the locking piece 414 contacts the outlet-side opening end, The locking piece 414 is engaged with the locking hole 434. In this state, the locking piece 414 is locked with the locking hole 434, and the connection state between the locking hook 413 and the locking hole 434 is maintained, so that the bag body 430 may be unintentionally detached from the base frame 410. It can be blocked more reliably. Further, when the locking piece 414 is removed from the locking hole 434, for example, the user pushes the protrusion 414b of the locking piece 414 by hand to release the engagement state between the protrusion 414b and the open end. With such a configuration, the state in which the locking hook 413 is inserted into the locking hole 434 can be maintained by the fitting structure, so that the anchor main body 430 can be more securely fixed to the base frame 410.

  The configuration of the bag with casters described above is an example, and it goes without saying that other configurations in which the bag body is mounted on the base frame can be used as appropriate. For example, the shape of the locking hook is not limited to the L shape, and a lockable structure such as a U shape or a V shape in sectional view can be used as appropriate. In the above example, the structure in which the locking hole is provided on the heel body side and the locking hook is provided on the base frame side has been described. Conversely, the locking hook is provided on the heel body side and the locking hole is provided on the base frame side. Can be realized. In this case, the locking hook protrudes when only the bag main body is used, but there is an advantage that it can be used for other purposes such as using the locking hook as a hook of the bag depending on the application. .

  Further, in the above example, the configuration has been described in which the slide portion is provided separately from the cylindrical portion, and the slide portion is slid independently of the cylindrical portion to switch between the lock position and the release position. However, the present invention is not limited to this configuration, and may be configured to slide a coupling mechanism such as a locking hook in conjunction with the operation of the cylindrical portion. For example, if the locking hook is configured to move up and down in conjunction with the expansion and contraction of the telescopic rod, the user does not have to squat down in order to operate the slide portion provided on the cylinder portion, and the user can engage in a comfortable posture. The stop hook can be switched between the lock position and the release position, and the operation of the lock hook can be further simplified.

  In this way, according to the present invention, it is possible to provide a caster-equipped scissors that can be easily attached and detached while maintaining the joining strength between the scissors body and the base frame.

  The bag with a caster of the present invention can be suitably used as a carrying case for business use, travel use, shopping use, etc., and also as a carriage for carrying goods.
