Description

  The present invention relates to a moving apparatus provided with casters.

  Conventionally, a cage with a caster at the bottom can move smoothly, but even if you want to keep the cage stationary, once you release your hand, There was a problem that the kite moved carelessly on slopes. In order to solve these problems, a caged caster with a stopper device capable of switching between a movable state and a movement-prevented state as disclosed in Patent Document 1 has been developed.

Utility Model Registration No. 3143133

  However, an apparatus as disclosed in Patent Document 1 needs to operate an operation unit attached in the vicinity of a caster using a hand or a foot. At this time, for example, when the operation is performed by hand, the user must bend and operate the operation unit. On the other hand, when the operation is performed with the foot, it is not necessary to bend, but there is a problem that the foot cannot be extended to the operation part depending on the stop direction of the caster and the operation is difficult. Such a problem is not limited to the bag alone, but may be a problem that may occur in general mobile devices such as carts and shopping carts provided with casters.

  The present invention has been made to solve the above-described problems, and provides a moving device that can easily switch between a movable state and a movement-preventing state in a moving device with casters by a hand operation. For the purpose.

  A moving device according to the present invention includes a moving body, at least one caster having a tire provided on the moving body and capable of moving the moving body, an operation unit that stops rotation of the tire, The movable body is provided at a position separated from the caster, and includes an operation unit that operates the operation unit, and a wire that connects the operation unit and the operation unit, and the operation unit is connected to the caster. And a brake member that comes into contact with the tire by pulling the wire from the operation unit side, and the operation unit includes a push button and at least a push state and a release state of the push button. A holding mechanism for holding the wire, and pulling the wire in the process of the push button reaching the pushed state, and releasing the wire pulled state in the released state Comprising a wire retraction mechanism, and in the press-down state, the tire has a rotation stopped state.

  According to this configuration, since the operation unit is provided at a position that is easy to operate such as a position away from the operation unit, for example, near the upper handle of the movable body, There is no need to operate with, and it can be operated easily. In addition, since the operation unit includes a push button, and a simple operation of pressing the button switches between the movable state and the movement prevention state, the operation unit can be easily operated. The moving device in the present invention can be applied to various moving devices provided with casters such as bags, carts, and shopping carts. For example, in the case of bags, the main body of the bag that stores articles is moved. In the carriage, the stage on which the article is placed becomes the moving body.

  In the above moving device, at least one of the operating part and the operating part is an absorption mechanism that absorbs the difference between the pulling amount of the wire or the pushing amount of the brake member and the pushing amount of the push button until the brake member comes into contact with the tire. Can be provided.

  In the moving device, the absorption mechanism is attached to the operation unit, and the holding mechanism can hold the push button in the pushed state when the push button is pushed by a predetermined push amount. . When the wire pull-in amount until the brake member comes into contact with the tire and enters the rotation stop state is smaller than the predetermined push amount, the push button is pushed to the predetermined push amount by elastically deforming the absorption mechanism. Can be.

  Further, in the moving device, the absorption mechanism is attached to the operating portion, and the holding mechanism can hold the push button in the pushed state when the push button is pushed by a predetermined push amount. . When the amount of pushing of the brake member until the brake member comes into contact with the tire and stops rotating is smaller than the predetermined pushing amount, the push button is pushed to the predetermined pushing amount by elastically deforming the absorption mechanism. Can be made.

  With this configuration, the following effects can be obtained. For example, depending on manufacturing error, tire and brake member wear, wire elongation, etc., until the brake member contacts the caster, the amount of wire retracted or the amount of brake member pressed, and until the push button is held in the pressed state The indentation amount may not match. In such a case, since the brake member does not come into contact with the caster even when the push button is pushed in completely, the brake cannot be applied. Alternatively, the brake may be applied before the push button is pushed into the pushed state, and at this time, the push button cannot be held in the pushed position. Therefore, when configured as described above, when the brake is applied before the push button is pushed, the absorption mechanism is elastically deformed so that the push button can be pushed further. Thereby, a pushbutton can be pushed in to a pushing state.

  Here, the absorption mechanism maintains its shape against pushing of the push button until the brake member comes into contact with the tire and stops rotating, and after the rotation stops, It can be configured to bend and be elastically deformed. According to this configuration, the absorbing mechanism maintains its shape until the brake member contacts the tire. Therefore, the wire is pulled by the wire drawing mechanism so as to correspond to the pushing amount of the push button (the wire is pulled by the amount that the push button is pushed in), and the brake member is pushed toward the tire. At this time, “maintaining the shape” does not mean maintaining the shape without elastic deformation at all, but means that some elastic deformation is allowed by pressing the push button. This point has the same meaning throughout this specification.

  In the moving device, the operation unit further includes a release button, and the push button can be released by pressing the release button.

  Further, in the above moving device, after the push button is pushed into at least one of the operation part and the operation part until the brake member comes into contact with the tire and the rotation is stopped, and the push button is pushed further, the brake member pushes the tire. A pressurizing mechanism for pressurizing can be further provided.

  In the moving device, the pressurizing mechanism is attached to the operation unit or the operating unit, and the holding mechanism can hold the push button at the position where the push button is pushed in when the push button is pushed in. . When the push button is further pushed after the brake member comes into contact with the tire and enters the rotation stopped state, the pressurizing mechanism is elastically deformed, so that the brake member pressurizes the tire with its restoring force. Can be configured.

  With this configuration, the push button can be further pushed in from the rotation stop state, and the restoring force of the pressurizing mechanism by the pushing acts to further pressurize the tire. And since a holding mechanism can hold | maintain in the position which pushed the pushbutton when the pushbutton was pushed in, it can hold | maintain a pushbutton in arbitrary positions. Along with this, the pushing amount of the pressurizing mechanism can be arbitrarily adjusted, so that the strength of the brake can be adjusted.

  Here, the pressurizing mechanism maintains its shape against the pushing of the push button until the brake member comes into contact with the tire and enters the rotation stopped state. It can be configured to bend and be elastically deformed. According to this configuration, the pressurizing mechanism maintains its shape until the brake member contacts the tire. Therefore, the wire is pulled by the wire drawing mechanism so as to correspond to the pushing amount of the push button (the wire is pulled by the amount that the push button is pushed in), and the brake member is pushed toward the tire.

  According to the moving device of the present invention, it is possible to easily switch between the movable state and the movement-prevented state by a hand operation.

More specifically, the pedestal 8 is attached to the frame 7 so as to be able to turn around a turning axis perpendicular to the bottom surface of the case body 1.

  As shown in FIGS. 1 and 2, an operating unit 10 that operates a brake on the tire 6 is attached to the bottom of the case body 1, that is, in the vicinity of the caster 5. On the other hand, an operation unit 20 for operating the operation unit 10 is attached to the upper portion of the case body 1, that is, in the vicinity of the handle 4. More specifically, the operation unit 20 is attached to the body 2 of the case body 1, and the operation units 10 are respectively attached to the two casters 5 a attached to the body 2. And the operation part 20 and each action | operation part 10 are each connected with the wire 40, and if the operation part 20 is operated, each action | operation part 10 will be operated simultaneously via each wire 40. FIG.

  Next, the operation part 10 will be described with reference to FIG. FIG. 3 is a sectional front view of the operating portion. As shown in the figure, the operating unit 10 is provided inside the case main body 1 above the caster 5 and includes a main body cover 11 that covers the operating unit 10. In the main body cover 11, a horizontal shaft 12 a is provided. A connecting member 12 that is pivotably attached and a brake member 13 that engages with one end of the connecting member 12 and presses the tire 6 are provided.

  The brake member 13 is formed of a working shaft 14 formed in a rod shape and a brake shoe 15 that is attached to the lower end of the working shaft 14 and presses the tire 6. And this brake member 13 penetrates the base 8 of the caster 5, and can move up and down. A brake release spring 16 is attached to the operating shaft 14 and biases the operating shaft 14 so that the brake shoe 15 is separated from the tire 6. By the way, the wire 40 described above is connected to the other end of the connecting member 12, and when the wire 40 is pulled, the connecting member 12 turns and the brake member 13 moves downward against the brake release spring 16. To be pushed into. On the other hand, when the pull of the wire 40 is released, the operating shaft 14 is biased by the brake release spring 16, and the brake shoe 15 is separated from the tire 6.

  Next, the operation unit 20 will be described with reference to FIGS. 4 is a partial cross-sectional front view of the operation unit, and FIG. 5 is an exploded view of the operation unit.

  As shown in FIGS. 4 and 5, the operation unit 20 has a main body case 21, and a push button 22 and the push button 22 are switched between an operating state and a non-operating state in the main body case 21. A holding mechanism for holding the wire 40 and a wire drawing mechanism for drawing the wire 40 are accommodated. The push button 22 is attached to the upper part of the main body case 21 and supported by a push-up spring 28 that constitutes a holding mechanism described later. More specifically, as shown in the exploded view of FIG. 5, a push-up spring 28 is disposed substantially at the center of the bottom surface of the main body case 21, and a button holder 29 is provided thereon, on which the push button 22 is placed. Is arranged.

  The wire pull-in mechanism is attached to the left and right of the main body case 21 with the push-up spring 28 interposed therebetween. That is, the wire drawing-in mechanism includes a wire drawing-in member 23 in which a rack 23a is formed at the upper part, a pinion 24, and a transmission member 25 in which a rack 25a is formed in the lower part. And the pinion 24 is pinched | interposed and the wire drawing member 23 is arrange | positioned outside and the transmission member 25 is arrange | positioned so that it may mutually mesh | engage. The wire drawing member 23 has a recess 23b formed in the lower part, and the wire 40 is attached to the recess 23b. The transmission member 25 has a spring receiver 25b formed on the upper portion thereof, and a wire pull-in amount adjustment spring (absorption mechanism) 26 is disposed on the spring receiver 25b. Two recesses 29a are formed in the button receiver 29, and each transmission member 25 is attached to each recess 29a with the lower surface of the spring receiver 25b of the transmission member 25 engaged. That is, the two transmission members 25 are attached to the push button 22, and the wire pull-in amount adjusting spring 26 is disposed between the push button 22 and the transmission member 25.

  The holding mechanism includes a pin 27 attached to the center of the button holder 29, a cam 30 slidably attached to the body case 21, and a push-up disposed substantially at the center of the bottom surface of the body case 21. And a spring 28. An inverted heart-shaped groove 31 with which the pin 27 engages is formed in the cam 30, and a lock spring 32 is attached to the pin 27. The lock spring 32 has a biasing force in a direction in which the pin 27 is pressed against the cam 30. The groove 31 is stepped, and the pin 27 cannot be raised by the urging force of the lock spring 32 and is formed so as to always advance in the reverse heart-shaped groove 31 in a certain direction. . With this configuration, when the push button 22 is pushed in, the pin 27 descends along the groove 31 of the cam 30 and stops at the predetermined position 31a. That is, the push button 22 is held in the depressed state. When the push button 22 is pressed again, the pin 27 is removed from the predetermined position 31a, and the push button 22 is raised and returns to the initial state. That is, the release state is established.

  Next, the operation of the suitcase configured as described above will be described with reference to FIGS. 6 shows the operation unit and the operation unit when the brake is OFF, FIG. 7 shows the operation when the brake is ON and the wire pull-in amount is minimum, and FIG.

  FIG. 6 shows an initial state where the brake is turned off. At this time, the push button 22 is raised, and the brake shoe 15 is not in contact with the tire 6. To operate the brake from this state, the push button 22 is pushed in as shown in FIG. At this time, due to the restoring force (repulsive force) of the wire pull-in amount adjusting spring 26, the wire pull-in amount adjusting spring 26 pushes down the transmission member 25 while maintaining a substantially natural length, whereby the transmission member 25 is lowered. As a result, the pinion 24 that meshes with the transmission member 25 rotates, and accordingly, the wire suction member 23 that meshes with the pinion 24 rises, and the wire 40 is pulled. When the wire drawing member 23 pulls the wire 40, the connecting member 12 turns as shown in FIG. 7B and pushes down the upper end of the operating shaft 14. Thereby, the brake shoe 15 presses the tire 6 of the caster 5, and the brake is activated. That is, the tire 6 is in a rotation stopped state.

  At the same time, as the push button 22 is depressed, the pin 27 attached to the button holder 29 also descends along the groove 31 of the cam 30. At this time, the pin 27 descends vertically according to the push button 22. However, since the cam 30 is slidably attached to the main body case 21, the cam 30 slides and the pin 27 is formed in an inverted heart shape. It is possible to descend smoothly along the groove 31 formed. The pushed push-down button 22 tends to rise due to the urging force of the push-up spring 28. At this time, the pin 27 engages with the predetermined position 31a of the cam 30. As a result, the push button 22 is held in the pushed state by the cam 30 and the pin 27. That is, as described above, the state in which the brake is operated is maintained, and the suitcase is in the movement preventing state. When the push button 22 is pushed again from this state, the pin 27 is removed from the predetermined position 31 a of the cam 30, and the push button 22 returns to the original position by the urging force of the push-up spring 28. At this time, since the pull of the wire 40 is released, the brake shoe 15 is separated from the tire 6 by the urging force of the brake release spring 16. As a result, the suitcase becomes movable.

  Next, the operation of the wire pull-in amount adjusting spring 26 will be described. The wire pull-in amount adjusting spring 26 is provided so that the brake shoe 15 can be pressed against the tire 6 with a constant pressing force even when manufacturing errors, tire and brake shoe wear, wire elongation, and the like occur. is there. In order to hold the state in which the brake is operated, the pin 27 needs to reach a predetermined position 31a of the cam 30, and it is necessary to push the push button 22 by a predetermined pushing amount until the pin 27 reaches the predetermined position 31a. When there is no problem of tire wear or the like, as shown in FIG. 7, when the brake shoe 15 comes into contact with the tire 6 and stops rotating, the wire 40 is not further pulled. Then, since the push-in of the push button 22 has not reached the predetermined push-in amount, the pin 27 does not reach the predetermined position 31a of the cam 30, and the brake cannot be held. Therefore, in this case, the remainder of the predetermined pushing amount of the push button 22 is absorbed by the wire drawing amount adjusting spring 26. That is, when the brake shoe 15 comes into contact with the tire 6 and stops rotating, when the push button 22 is further pushed, the wire pull-in amount adjusting spring 26 is contracted, and the push button 22 can be pushed to a predetermined push amount. . Thereby, the operating state of the brake can be maintained.

  On the other hand, when problems such as tire wear occur due to manufacturing errors or the use of suitcases, the wire 40 is pulled up to the point where the brake shoe 15 contacts the tire 6 and the wire pull-in amount adjusting spring 26 absorbs it. The amount to be automatically reduced. Finally, as shown in FIG. 8, the wire drawing member 23 is pulled up by a predetermined pushing amount of the push button 22 without substantially contracting the wire drawing amount adjusting spring 26. As a result, the caster cannot be installed at the design position due to manufacturing errors, the tire and the brake are opened from the design distance due to wear of the tire and the brake, or the wire 40 is designed with a predetermined pull-in amount due to the elongation. Even when the wire 40 can no longer be retracted, a predetermined pressing force can be applied to the tire 6 by reducing the absorption amount (shrinkage amount) of the wire pull-in amount adjusting spring 26.

  As described above, according to the present embodiment, since the operation unit 20 is provided at the top of the case body 1, that is, at hand, there is no need to operate with a foot or bend and operate with a hand. As a result, the brake can be operated easily. Further, since the operation unit 20 includes the push button 22 and can be switched between the movable state and the movement prevention state by a simple operation of pressing the push button 22, the operation can be easily performed. Further, the operation unit 20 includes a wire pull-in amount adjustment spring 26. When the wire pull-in mechanism pulls in the wire 40 is smaller than a predetermined push-in amount of the push button 22, the wire pull-in amount adjustment spring 26 is The predetermined pressing amount of the operation button 22 can be absorbed. As a result, even if there is an error in the initial design due to manufacturing errors, tire and brake wear, wire elongation, etc., it is possible to obtain a pressing force equivalent to the pressing force required in the initial design, and reliably prevent movement. State.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. For example, in the above embodiment, the operation unit 20 is disposed on the upper portion of the case body 1, but may be disposed at any position of the case body 1 as long as it can be operated by hand without bending the body. it can.

  Further, in the above embodiment, the operation button 22 is controlled to be switched between the operating state and the non-operating state by the pin 27 and the cam 30. However, as shown in FIG. And can be controlled by a ratchet mechanism. More specifically, the rack member 52 is attached to the button holder 29, and the pivot member 53 including the pinion 53a and the gear 53b is pivotally attached to the main body case 21. A pawl 54 is attached to the release button 51, and the pawl 54 is pivotally attached to the main body case 21. The rack member 52 and the pinion 53a mesh with each other, and the pawl 54 and the gear 53b mesh with each other. At this time, the pawl 54 and the gear 53b constitute a ratchet mechanism. When the push button 22 is pushed down, the rack member 52 descends and the pinion 53a rotates. At the same time, the gear 53b rotates to change the position where it engages with the pawl 54, and the push button 22 is held in a pressed state. When the release button 51 is pressed, the meshing between the pawl 54 and the gear 53b is released, and the push button 22 returns to the original position by the urging force of the push-up spring 28.

  With such a configuration, since the push button 22 is held in the state where the push button 22 is pushed, the push button 22 can be held at an arbitrary position. In other words, the push button 22 can be fastened while the brake member 13 is in contact with the tire 6, and the push button 22 can be fastened when the push button 22 is further pushed from this state. When the brake member 13 is further pushed after coming into contact with the tire 6, the wire draw-in amount adjusting spring (pressurizing mechanism) 26 is pushed in due to contraction (elastic deformation). At this time, the wire draw-in amount adjusting spring 26 is pushed. The reaction force (restoring force) generated from the above is further added to the tire 6. Thus, the more the push button 22 is pushed, the greater the reaction force of the wire pull-in amount adjusting spring 26, so that the force that pressurizes the tire 6 by the brake member 13 can be increased. As a result, the effectiveness of the brake can be adjusted according to the push amount of the push button 22.

  In the above embodiment, each transmission member 25 includes the wire pull-in amount adjusting spring 26 and individually adjusts the pull-in amount of the wire 40. However, as shown in FIG. Even when only one piece is provided and the wire pull-in amount is different from each other, the wire pull-in amount can be adjusted individually. More specifically, the spring holder 62 is arranged at the approximate center of the button holder 29, and the wire drawing amount adjustment spring 61 is arranged on the spring holder 62. A motion transmission amount adjusting member 63 is attached to the spring receiver 62 so as to be pivotable, and each transmission member 64 is attached to the motion transmission amount adjusting member 63. When the left and right wire pull-in amounts are different, the motion transmission amount adjusting member 63 pivots to absorb the difference between the left and right wire pull-in amounts.

  Furthermore, in the said embodiment, although the coil spring was used for the wire drawing-in amount adjustment spring 26, as shown in FIG.11 and FIG.12, a leaf | plate spring can be used for the wire drawing-in amount adjustment spring 71. FIG. Below, the example of the operation part 20 using a leaf | plate spring is shown. More specifically, the wire pull-in amount adjusting spring 71 is formed in a U-shape when viewed from the front, and both ends thereof are bent outward. The operation unit 20 includes a main body case 21, and an adjustment spring holder 72 is pivotably attached to the approximate center of the main body case 21. The adjustment spring holder 72 is attached by hooking both bent ends of the wire pull-in amount adjustment spring 71. In addition, the adjustment spring holder 72 is formed with a receiving portion 72a to which the wire drawing member 73 is attached at one end. The wire drawing member 73 has an upper end formed to be engageable with the receiving portion 72 a of the adjustment spring holder 72, and a lower end formed to be able to hold the wire 40. Further, a push-up spring 74 having a C-shape in front view is integrally formed at the center lower end of the adjustment spring holder 72. When attached in this way, one end of the wire pull-in amount adjustment spring 71 extends to the end opposite to the end to which the wire pull-in member 73 is attached across the pivot shaft of the adjustment spring holder 72. Further, there is another set of wire pull-in amount adjustment spring 71, adjustment spring holder 72, wire pull-in member 73, and push-up spring 74, which are attached to the main body case 21 in the front-rear direction in a state of being reversed left and right. . At this time, the push-up spring 74 is also attached to the lower end of the main body case 21. The push button 75 is formed such that the lower portion thereof is inclined toward the lower outer side from the center, and is inclined in the opposite direction in the front-rear direction in the front view. The lower end of the push button 75 is placed on the end of the wire pull-in amount adjustment spring 71. Note that a pin 27 is attached to the push button 75 and a cam 30 is attached to the main body case 21 although not shown.

  The operation of the wire pull-in amount adjusting spring 71 as described above will be described with reference to FIG. FIG. 13A is a front view of the operation unit when the brake is ON and the wire pull-in amount is minimum, and FIG. 13B is a front view of the operation unit when the brake is ON and the wire pull-in amount is maximum. When the push button 75 is pushed in, the lower end of the push button 75 pushes down the wire pull-in amount adjustment spring 71, so that the adjustment spring holder 72 turns. Thereby, the wire drawing member 73 is pulled up and the wire 40 is pulled simultaneously. The operation of the operating unit 10 at this time is the same as when the coil spring is used. When there is no problem such as tire wear, the wire pull-in amount adjusting spring 71 needs to contract. In this case, as shown in FIG. 13A, the U-shaped opening is narrowed and the leaf spring is contracted. On the other hand, when problems such as tire wear occur due to manufacturing errors or the use of suitcases, the amount absorbed by the wire pull-in amount adjusting spring 71 automatically decreases accordingly. Finally, as shown in FIG. 13B, the wire drawing member 73 is pulled up by a predetermined pushing amount of the push button 75 without substantially contracting the wire drawing amount adjusting spring 71.

  By having this configuration, even if an initial setting and an error occur due to manufacturing errors, tire and brake wear, wire elongation, etc., a pressing force equivalent to the pressing force requested in the initial setting can be obtained. In addition, the number of parts used for the operation unit 20 can be reduced. Thereby, the operation part 20 becomes lightweight, the suitcase as a whole can be reduced in weight, and can be manufactured at low cost.

  Moreover, in the said embodiment, although the wire drawing amount adjustment spring 26 was provided in the operation part 20 as an absorption mechanism, and the difference between the pushing amount of the pushbutton 22 and the drawing amount of the wire 40 was adjusted, A brake pressing amount adjusting spring (absorption mechanism) 81 that adjusts the difference between the pressing amount of the member 13 and the pressing amount of the push button 22 can also be provided. Specifically, the connecting member 80 provided in the operating unit 10 includes a brake pressing amount adjusting spring 81 and a main body 82. As shown in FIGS. 14 and 15, the brake movement amount adjustment spring 81 is formed as a plate spring having a U-shape when viewed from the front. The brake movement amount adjusting spring 81 is attached to the main body 82 so as to extend and contract in the vertical direction. Similar to the above embodiment, the connecting member 80 is pivotally attached to the main body cover 11 by the horizontal shaft 12a. The brake member 13 is provided on the U-shaped opening side 81a of the brake pressing amount adjusting spring 81, and the wire 40 is connected to the other end side 82a. When the wire 40 is pulled, the connecting member 80 turns and the brake member 13 is pushed downward. When there is no problem such as tire wear, the brake push-in amount adjusting spring 81 configured in this way needs to shrink the brake push-in amount adjusting spring 81 and shrinks so that the U-shaped opening is narrowed. On the other hand, when problems such as tire wear occur due to manufacturing errors or the use of suitcases, the amount absorbed by the brake pressing amount adjusting spring 81 automatically decreases accordingly. Eventually, the brake pressing amount adjusting spring 81 is not substantially contracted, and the brake member 13 is pressed by a predetermined pressing amount of the push button 22. In this case, the operation unit 20 does not need to be provided with the wire pull-in amount adjustment spring 26, and may have the push button 22, the holding mechanism, and the wire pull-in mechanism. As described above, the structure of the operation unit 20 can be simplified by providing the operation mechanism 10 instead of the operation unit 20, and the absorption mechanism 81 of the operation unit 10 does not need a complicated structure. And can be easily manufactured.

  Even in the configuration in which the operating portion or the operating portion described above is provided with a leaf spring-shaped absorption mechanism, the operating portion is configured as shown in FIG. 9, the release button 51 is provided beside the push button 75, and the ratchet mechanism is operated. It is possible to control by switching between a state and a non-operating state. In this case, the leaf spring-shaped absorption mechanism functions as a pressurizing mechanism, and the pressurizing mechanism operates in the same manner as described with reference to FIG. In other words, since the push button 75 is held at the position where the push button 75 is pressed, the push button 75 can be held at an arbitrary position. When the push button 75 is further pushed after the brake member 13 comes into contact with the tire 6, the wire pull-in amount adjusting spring (pressurizing mechanism) 71 or the brake push-in amount adjusting spring (pressurizing mechanism) 81 is contracted (elastically deformed). Will be pushed. At this time, reaction force (restoring force) generated from the pressurization mechanisms 71 and 81 is further applied to the tire 6. In this manner, the reaction force of the pressurizing mechanisms 71 and 81 increases as the push button 75 is pushed in, so that the force that pressurizes the tire 6 by the brake member 13 can be increased. As a result, the effectiveness of the brake can be adjusted according to the push amount of the push button 75.

  Furthermore, the absorption mechanism or the pressurizing mechanism may be a tension spring disposed between the wire 40 and the wire drawing members 23 and 73, for example. In this case, the absorption mechanism or the pressure mechanism is extended (elastically deformed) to absorb the push amount of the push button 22 or pressurize the tire 6 according to the push amount of the push button 22. Can do.

  In the said embodiment, as shown in FIG. 1, although the operation part is provided in two casters, you may provide only in one caster and may provide in three or more casters. At this time, the wire drawing-in mechanism is provided with the number of operating parts, and is configured to operate all the operating parts with push buttons. Moreover, in the said embodiment, although the operation part 20 and the action | operation part 10 are provided in the body 2 of the suitcase, it can also be provided in the lid | cover 3 and can also be provided ranging over both a body and a lid | cover. Moreover, although the example using the pin 27 and the cam 30 was shown as a holding mechanism in the said embodiment, it is not limited to this, If the pushing of the pushbutton 22 reaches predetermined pushing amount, a pushing state can be hold | maintained. If there is, it is not particularly limited. Furthermore, in the said embodiment, the brake structure has shown the structure which uses the connection member 12 attached with the horizontal axis | shaft 12a so that a pivot is possible, and when the wire 40 is pulled, the brake member 13 will be pushed and a brake will be applied. However, the brake structure is not limited to this, and is not particularly limited as long as the brake structure is such that the brake is applied by pulling the wire with a required force.

  Furthermore, in the said embodiment, although the example which applied the moving apparatus of this invention to the suitcase was shown, it is not limited to this, It applies also to a bag etc. which provided the caster in the bottom part of the tote bag. be able to. In addition, the present invention is not limited to bags, and can be applied to all mobile devices having casters such as carts, shopping carts, silver cars, and strollers.
