Description

  The present invention relates to a kite that is provided with four casters on the bottom surface and can move in a free direction in a horizontal plane while being self-supported by the casters. In particular, in a state where there is no need to move, the horizontal direction of the casters is specified. The present invention relates to a bag having casters that can prevent movement.

  A cage that has four casters on the bottom and can move in any direction independently by the casters can be used conveniently. However, this kite has a drawback that it moves due to the inclination of the road surface or the inertia of the acceleration or deceleration of the train even when it is not necessary to move. In order to eliminate this drawback, a structure has been developed in which the wheels of the casters are stopped by a brake so as not to rotate. (See Patent Document 1)

  This hook has a drawback that the outer periphery of the wheel is likely to be distorted because the outer periphery of the wheel is stopped by pressing locally with a brake so as not to rotate. If the outer periphery of the wheel is distorted, vibration will occur when the bag is moved, making it impossible to move comfortably.

  In order to eliminate this drawback, a kite has been developed in which the caster is stopped in a horizontal or reverse square shape in a horizontal plane so that it cannot move. (See Patent Document 2)

Japanese Patent Laid-Open No. 11-56438 Japanese Patent No. 4863351

  The anchor that stops the movement in the horizontal or horizontal direction of the caster can stop the movement in the state that the four casters are in the H-shaped or reverse-C-shaped, but depending on the direction There is a drawback that the rotation of the kite in the horizontal plane cannot be stopped. In addition, this hook has a C-shaped or reverse H-shaped direction in the horizontal plane of the caster, so that when the hook is stopped, the hook moves slightly or rotates slightly to ensure that it is in place. There is a fault that cannot be fixed. This is because the movement of the kite is stopped with the direction of the caster as the direction inclined with respect to the direction of movement of the kite. A kite that moves slightly while stopped cannot always be used conveniently. This type of kite is in a locked state that stops moving mainly when riding on a train, etc., but a kite that moves slightly in this state moves with acceleration when the train is accelerated or stopped, or when turning on a curve Since it is necessary for the user to hold it, it cannot be used conveniently. This is because it is necessary to surely prevent harmful effects such as the movement of a kite and collision with a neighbor.

  The present invention has been developed for the purpose of solving the above-mentioned drawbacks. An important object of the present invention is to provide a kite having a caster that can reliably stop both movement and rotation of the kite in a stopped state.

Means for Solving the Problems and Effects of the Invention

The cage having the caster of the present invention has a cage main body 3 having a horizontal cross-sectional shape of a quadrangle, and extends in the horizontal direction above the cage main body 3 and in a direction parallel to one side of the quadrangular cage main body 3. A handle 2 which is provided in an extending posture and moves the heel body 3; four casters 1 which are rotatable in a horizontal plane fixed to the four corners of the bottom surface of the heel body 3 having a rectangular horizontal cross-sectional shape; The four casters 1 are provided with a stopper mechanism 5 configured to stop the movement of the rod main body 3 by stopping the horizontal direction of the four casters 1 in the stop direction in which the movement of the rod main body 3 is stopped. In this bag, the bag body 3 is set in a self-supporting state by the four casters 1 and the caster 1 can be rotated in a horizontal plane so that the handle body 2 can be moved by pressing the handle 2. Further, the kite stops the horizontal direction of the caster 1 in the stop direction by the stopper mechanism 5 to stop the movement of the kite body 3. Furthermore, the stopper mechanism 5 stops the movement of the bag main body 3 with the stop direction of the four casters 1 as the following (A) or (B) direction.
(A) The stop direction of the four casters 1 is substantially parallel to any one side of a quadrangle whose four corners are the connection positions of the four casters 1, and the horizontal direction of the casters 1 arranged next to each other In which the horizontal directions of the pair of casters 1 that are diagonal to each other are parallel to each other.
(B) The stop direction of the four casters 1 is substantially parallel to any one side of a quadrangle whose four corners are the connection positions of the four casters 1, and the pair of casters 1 that are diagonal to each other. The directions are perpendicular to each other.
In the present specification, “the stop direction of the four casters is substantially parallel to any one side of a quadrangle whose four corners are the connection positions of the four casters” means any one of the stop direction and the quadrangle. It is used in a broad sense including a state where the angle between two sides is within 30 degrees.

The kite having the above casters has a feature that can reliably stop both movement and rotation of the kite in the stopped state. That is, in the stop state, the above-mentioned heel stops the movement of the heel by stopping the stop direction of the two casters in a direction perpendicular to the direction in which the user pushes the handle in the longitudinal direction and moves the heel body. Because it does.
The conventional hook that locks the caster in the direction of the stop direction with a C-shape or reverse-H-shape stops the caster in a posture that tilts about 45 degrees with respect to the moving direction. You cannot stop when you cannot move. When the handle is pushed and the heel moves, the movement trajectory of the pair of casters arranged in a letter C shape or a reverse letter C shape becomes narrower or wider, thereby stopping the movement of the heel. It is.
On the other hand, the above hooks stop moving with two casters facing in a direction orthogonal to the moving direction. The caster can move smoothly in the direction in which the wheel rotates, but does not move in the lateral direction in which the wheel does not rotate. For this reason, the above-described kites can be stopped without moving the kites in a stopped state. Therefore, this kind of kite can be stopped in an ideal locked state where it does not move at all in a state where the kite stops moving on a moving train or the like, which is the main application. In addition, the above-mentioned ridges are such that the stop direction of the casters is substantially parallel to any one side of the quadrangle whose four corners are the connection positions of the four casters, and the horizontal direction of the casters arranged next to each other is mutually Since the directions are perpendicular to each other, or the horizontal directions of the pair of casters at diagonal positions are perpendicular to each other, there is a feature that the rotation of the kite can be reliably stopped in the stopped state.
This type of kite can be used conveniently when stopped on a crowded train or the like. For example, it is assumed that a user sits on a train seat and puts a heel between both feet or outside to stop the movement. If the kite moves or rotates in this state, the kite may collide with neighbors or nearby people, causing trouble. In particular, even in a crowded vehicle, even if the bag moves slightly or rotates, the bag may touch the neighbors and cause trouble. The bag of the present invention can stop the movement and rotation of the bag surely by setting the direction of the caster to be a specific direction. Therefore, in a crowded vehicle, the bag is stopped and collides with the next person and is annoying. There is a feature that users can use it safely and conveniently.

In the bag having the casters of the present invention, the angle between the stop direction of the four casters 1 and any one side of the quadrangle having the connection positions of the four casters 1 as four corners can be within 15 degrees. .
The above kite can move the stop direction of one caster between a pair of casters adjacent to each other at right angles to each other by a rotating shaft that rotates in the horizontal plane of the other caster. Can be stopped reliably.

The bag having casters according to the present invention includes a bag body 3 having a base plate 4 having a rectangular outer shape and a detachable bar 3A detachably mounted on the base plate 4, and the casters 1 are connected to the four corners of the base plate 4. It can be set as a structure.
Since the above-mentioned ridges are placed on the base plate so that the detachable ridges can be removed, the detachable ridges having different sizes and shapes can be placed on the base plate having the same shape. Also, by connecting casters to the four corners of the base plate, the casters can be easily and firmly fixed to the bag body.

The scissors having the casters of the present invention can be stopped by the stopper mechanism 5 in conjunction with the horizontal direction of the four casters 1 in the stop direction.
Since the four casters can be stopped together with the stopper mechanism in the stop direction by the stopper mechanism, the movement state and the stop state can be easily switched.

In the bag having the casters of the present invention, the stopper mechanism 5 can be provided with a lock switch 27 for switching between the rotation and stop of the four casters 1.
The above hook can be easily switched between a state in which the four casters can be freely moved and a state in which the movement is stopped by operating the lock switch.

The scissors having the casters of the present invention can stop the casters 1 in two stop directions different from each other by 180 degrees with the stopper mechanism 5.
The above hooks can be quickly stopped in the stop direction without the stopper mechanism rotating the caster 180 degrees or more.

In the bag having the caster of the present invention, the outer periphery of the wheel 15 of the caster 1 can be a rubber-like elastic body.
This saddle has a feature that prevents the caster from slipping in the stopped state and can stop so as not to move the saddle body in the stopped state. This is because by making the outer periphery of the wheel a rubber-like elastic body, it is possible to increase the frictional resistance between the wheel facing in the direction orthogonal to the direction in which the kite is transferred and the road surface.

A lock mechanism (not shown) that stops in a locked state at a position is provided. The lock mechanism pushes the operation button 2A provided at the center of the upper surface of the handle 2 to release the locked state and move the handle 2 up and down.

  In the telescopic rod 21 in this figure, the rods are connected so that they can be expanded and contracted in three stages. However, the present invention is not limited to this, and can be two stages or four stages depending on the specification. In addition, the handle can be connected to the base plate via a rod that does not expand and contract. This hook locks the handle to the bottom when storing or when the user lifts and moves. It is stored in this state, or the user holds the handle and lifts the bag to move. When moving on a caster, lift the handle to the top and push the handle to move.

  The base plate 4 has casters 1 that can swing freely at four corners. The cross-sectional view of FIG. 3 shows a portion for connecting the caster 1 to the base plate 4. In the base plate 4 in this figure, fixing portions 24 for connecting the casters 1 are fixed to the four corner portions. The fixing portion 24 is provided with a cylindrical fitting recess 24A for inserting and fixing the caster 1 so as to open downward. Furthermore, the fixing portion 24 is provided with a through hole 24X through which a projecting pin 10 of the stopper mechanism 5 described later enters and exits.

However, the present invention is not limited to the structure in which the heel body is necessarily connected to the base plate so that the detachable heel can be detached, and the casters can be directly connected to the four corners of the bottom surface of the heel body.

  The above scissors are brought into a state in which the scissors main body 3 is self-supported by four casters 1, and the handle 2 is pushed and moved in the longitudinal direction. Moreover, the horizontal direction of the caster 1 that can be swung by the stopper mechanism 5 is stopped in the stop direction, so that the movement of the bag main body 3 can be in a stopped state. The stopper mechanism 5 stops the movement of the bag main body 3 with the stop direction of the four swingable casters 1 as the direction (A) or (B) below.

(A) The stop direction of the four casters 1 is substantially parallel to any one side of a quadrangle whose four corners are the connection positions of the four casters 1, and the horizontal direction of the casters 1 arranged next to each other In which the horizontal directions of the pair of casters 1 that are diagonal to each other are parallel to each other.

  The above state is shown in the schematic bottom view of FIG. In this stop state, the four casters 1 face in the direction in which the adjacent ones are orthogonal to each other. Therefore, when the kite tries to move in the direction indicated by the arrow A, the wheels 15a and 15c orthogonal to the moving direction are Stop moving. Further, when trying to move in the direction indicated by the arrow B, the wheels 15b and 15d perpendicular to the moving direction stop moving. Further, when the kite is about to rotate, all the wheels 15 stop rotating.

(B) The stop direction of the four casters 1 is substantially parallel to any one side of a quadrangle whose four corners are the connection positions of the four casters 1, and the pair of casters 1 that are diagonal to each other. The directions are perpendicular to each other.

  The above state is shown in the schematic bottom views of FIGS. In this stop state, the four casters 1 face in directions orthogonal to each other diagonally. Therefore, when the bag in FIG. 5 tries to move in the direction indicated by the arrow A, the wheel 15c and the wheel 15d orthogonal to the moving direction stop moving and when the wheel 15c tries to move in the direction indicated by the arrow B, The wheels 15a and 15b that are orthogonal to the moving direction stop moving. When the kite is about to rotate, the wheels 15a and 15b stop rotating. 6 is moved in the direction indicated by the arrow A, the wheels 15b and 15c perpendicular to the moving direction stop moving, and the movement in the direction indicated by the arrow B is the moving direction. The wheel 15a and the wheel 15d that are orthogonal to each other stop moving. When the kite is about to rotate, the wheels 15b and 15c stop rotating.

  In addition, the stop direction of the caster 1 shown in FIGS. 4 to 6 is parallel to any one side of a quadrangle having four corners at the connection positions of the four casters 1. However, in the bag of the present invention, the stop direction of the four casters can be set to be in a state of being slightly inclined with respect to any one side of the quadrangle. In the bag of the present invention, the angle formed between the stop direction of the caster and any one side of the quadrangle can be within 30 degrees, preferably within 15 degrees.

  The stopper mechanism 5 can move in such a manner that the horizontal direction of the caster 1 is stopped in the direction shown in FIGS. 4 to 6 so that the hook is stopped and the caster 1 can be freely rotated in a horizontal plane. The state, that is, the moving state.

  The stopper mechanism 5 interlocks the horizontal direction of the four casters 1 in the stop direction and switches between the moving state and the stopped state. The stopper mechanism 5 includes an operation unit 6 provided on the reinforcing rod 23 of the telescopic rod 21 and a lock unit 8 connected to the operation unit 6 with a wire 7. When the user operates the operation unit 6, the lock unit 8 stops the direction of the caster 1 in the stop direction and sets the stop state. Further, the operation unit 6 is operated to switch to the moving state.

  As shown in FIGS. 7 to 10, the operation unit 6 pulls the wire 7, stops the direction of the caster 1 in the stop direction, puts the caster 1 into a moving state without pulling the wire 7. . The operation unit 6 includes a reciprocating block 26 disposed inside the reinforcing rod 23 so as to reciprocate in the longitudinal direction, and a lock switch 27 connected to the reciprocating block 26 and projecting outside the reinforcing rod 23. Consists of. The reciprocating block 26 is disposed inside a guide tube 25 fixed in the longitudinal direction inside the reinforcing rod 23, and reciprocates in the axial direction (longitudinal direction of the reinforcing rod 23) along the inner surface of the guide tube 25. I can do it. The lock switch 27 is connected to the reciprocating block 26 via a connecting rod 28. The connecting rod 28 is inserted into a guide hole 26A of the reciprocating block 26 so as to enter and exit the guide hole 26A, and the connecting rod 28 is narrower than the inserting portion 28B and is connected to a knob as a lock switch 27 at the tip. It consists of a rod portion 28A. 26 A of guide holes incorporate the spring 29 of a coil spring between insertion part 28B. The pressing spring 29 elastically presses the insertion portion 28 </ b> B of the connecting rod 28. The guide cylinder 25 is provided with a slit 25 </ b> A in the longitudinal direction on the side surface thereof to penetrate the rod portion 28 </ b> A of the connecting rod 28. The reciprocating block 26 moves in the axial direction of the guide tube 25 by moving the rod portion 28A along the slit 25A. The slit 25 </ b> A guides the rod portion 28 </ b> A in the longitudinal direction and moves the reciprocating block 26 in the axial direction of the guide cylinder 25. In order to stop the reciprocating block 26 at the pulling position of the wire 7, a lock opening 25 </ b> B that guides the insertion portion 28 </ b> B of the connecting rod 28 is connected to the end of the slit 25 </ b> A. The lock opening 25B is wider than the width of the slit 25A, and has an inner shape that can guide the rectangular columnar insertion portion 28B.

  In the operation unit 6 described above, the lock switch 27 is moved in the direction of pulling the wire 7 as shown by the arrows in FIGS. 9 and 10, and the rod portion 28A is moved along the slit 25A. When the rod portion 28A moves to the end of the slit 25A, the insertion portion 28B of the connecting rod 28 is pushed by the push spring 29 and guided to the lock opening 25B. In this state, the reciprocating block 26 holds the wire 7 in a pulled state. This is because the insertion portion 28B is guided to the lock opening 25B, thereby preventing the reciprocating block 26 from being pulled back by the wire 7 and returning. Since the state in which the wire 7 is pulled by the reciprocating block 26 is a stopped state in which the movement of the kite is stopped, the kite is held in a state where it does not move in this state.

  When switching the heel to the moving state, the push spring 29 is compressed, the lock switch 27 is pushed so as to insert the insertion portion 28B into the guide hole 26A, and the insertion portion 28B is pushed out from the lock opening 25B to the inside of the guide hole 26A. Then, the rod portion 28A is guided to the lock opening 25B. In this state, the rod portion 28A is moved along the slit 25A, and the reciprocating block 26 is moved to the return position, that is, the position where the wire 7 is not pulled.

  The wire 7 is inserted into the wire tube 7 </ b> A, and has one end connected to the lock switch 27 of the operation unit 6 and the other end connected to the slide block 30 of the lock unit 8. The wire tube 7A extends from the reinforcing rod 23 to the base plate 4 so that the inner wire 7 can smoothly reciprocate. When the lock switch 27 of the operation unit 6 is slid in the pulling direction, the wire 7 is pulled by the reciprocating block 26 and transmits the traction force to the slide block 30. Conversely, when the lock switch 27 of the operation unit 6 is slid in the return direction, the wire 7 is pushed by the reciprocating block 26 to return the slide block 30 or the slide block 30 is urged in the return direction. As a result, the reciprocating block 26 is pulled and the slide switch 27 is returned.

  As shown in FIGS. 11 to 14, the lock portion 8 is disposed on the lower surface of the base plate 4, and reciprocates with the wire 7, and the reciprocating motion of the slide block 30 causes the yoke 14 of the caster 1 to move. And a protruding pin 10 that enters and exits.

  The slide block 30 reciprocates on the lower surface of the base plate 4 so that the projecting pins 10 arranged on both sides of the slide block 30 enter and exit toward the yoke 14 of the caster 1. The slide block 30 shown in FIGS. 11 to 14 includes an elongated straight portion 31 disposed at the center of the base plate 4 and pressing block portions 32 provided at both ends of the straight portion 31. The straight part 31 is connected to one end of the wire 7 and is driven by the wire 7 to move the slide block 30 in the reciprocating direction. The slide block 30 shown in the figure slides in the direction indicated by the arrow in FIG. 13 when the straight portion 31 is pulled by a wire, and conversely, the straight portion 31 is pushed by the wire 7 or the slide block 30 is reversed. It slides in the direction opposite to the arrow of FIG. 13 through the elastic body biased in the direction. Here, a dedicated coil spring can be provided as an elastic body for urging the slide block 30 in the reverse direction, but as shown in the drawing, a first pressing spring 37A described later can also be used. . Furthermore, the slide block 30 shown in the drawing also includes an operation unit 33 that forcibly moves the stopper mechanism 5 in the reciprocating direction when the stopper mechanism 5 is malfunctioning. The slide block 30 shown in FIG. 11 is provided with a convex portion that protrudes from the lower surface of the straight portion 31 as the operation portion 33, and the slide block 30 can be slid by directly operating the convex portion.

  A guide case 34 is disposed on the lower surface of the base plate 4 in order to reciprocate the slide block 30 in a predetermined direction. The guide case 34 has peripheral walls 34a, 34b, 34c, and 34d along the outer periphery of the slide block 30, and the slide block 30 is accommodated inside the peripheral walls 34a, 34b, 34c, and 34d. The guide case 34 shown in FIGS. 11 to 14 has a slide groove 34 </ b> A for guiding the straight portion 31 in the central portion, and a storage space 34 </ b> B for guiding the pressing block portion 32 at both ends. The slide groove 34A guides the straight portion 31 between the opposed peripheral walls 34a, and reciprocates the straight portion 31 along the inner surface of the slide groove 34A. The storage spaces 34B provided at both ends of the slide groove 34A have a shape that allows the pressing block 32 stored therein to reciprocate in the direction indicated by the arrows in the figure. The guide case 34 has a first storage space 34Bx for storing the first pressing block portion 32X located on the left side in the drawing and a second storage for storing the second pressing block portion 32Y positioned on the right side in the drawing. And a space 34By. Further, the cover case 34 described above closes the openings of the peripheral walls 24a, 34b, 34c, and 34d with a cover plate 35 (indicated by a one-dot chain line in the drawing). The cover plate 35 covers the entire cover case 34 and a part of the periphery of the cover case 34 to prevent members housed therein from falling or foreign materials from entering the inside. Further, the cover plate 35 shown in the figure has an opening window 35A that exposes the operation portion 33 provided on the straight portion 31 to reciprocate.

  The pressing block portions 32 provided at both ends of the straight portion 31 are disposed between a pair of casters 1 facing each other at both ends of the base plate 4. The pressing block 32 reciprocates the protruding pins 10 arranged on both sides to the protruding position and the retracted position toward the yoke 14 of the opposite caster 1 in a state where the slide block 30 is reciprocated. The pressing block 32 includes projecting inclined surfaces 32A projecting on both sides, and the projecting pin 10 is moved between the projecting position and the retracted position via a moving block 36 that moves along the projecting inclined surface 32A. The pressing block 32 slides the moving block 36 along the projecting inclined surface 32 </ b> A while sliding in the direction indicated by the arrow in FIG. 12, and moves the projecting pin 10 toward the caster 1. The pressing block portion 32 shown in FIG. 12 is provided with a protruding inclined surface 32A so that the moving block 36 can be moved in the direction in which the protruding pin 10 protrudes in a state where the slide block 30 slides in the direction indicated by the arrow in the drawing. . The slide block 30 shown in FIG. 13 is provided with two pressing block portions 32 including a first pressing block portion 32X and a second pressing block portion 32Y at both ends of the straight portion 31. The first pressing block portion 32X moves in the direction indicated by the arrow in the figure, and has a protruding slope that protrudes on both sides as a shape that tapers in the moving direction, that is, a shape that increases the width on the rear end side. A surface 32A is provided. The second pressing block portion 32X is provided with a projecting inclined surface 32A projecting on both sides as a shape whose width on the rear end side becomes wider with respect to the moving direction in a state of moving in the direction indicated by the arrow in the drawing. The above slide block 30 pushes the protruding pin 10 to the protruding position at the forward position shown in FIGS. 13 and 14, and retracts the protruding pin 10 to the retracted position at the retracted position shown in FIG. 11. Further, the slide block 30 moves the moving blocks 36 arranged on both sides of each pressing block portion 32, that is, the four moving blocks 36 at the same time in a reciprocating motion.

  The moving block 36 is disposed opposite to both sides of the pressing block portion 32, slides along the protruding inclined surface 32 </ b> A of the pressing block portion 32 that reciprocates, and is orthogonal to the reciprocating direction of the slide block 30. Move horizontally. The moving block 36 shown in FIG. 12 has a sliding portion 36A at the boundary with the protruding inclined surface 32A, and the sliding portion 36A is slid along the protruding inclined surface 32A of the pressing block portion 32, The moving block 36 is moved toward or away from the opposite caster 1. That is, each moving block 36 slides the sliding portion 36A along the protruding inclined surface 32A of the pressing block portion 32 that reciprocates so that the moving block 36 moves in the reciprocating direction of the slide block 30 (the longitudinal direction of the base plate 4). ) Is reciprocated in a horizontal direction (short direction of the base plate 4) perpendicular to the vertical direction. The illustrated guide case 34 is provided with guide grooves 34C on both sides of the storage space 33B in order to move the moving block 36 in a predetermined direction. The guide groove 34 </ b> B is provided to extend in the horizontal direction perpendicular to the reciprocating direction of the slide block 30, that is, in the short direction of the base plate 4. The guide groove 34C guides the moving block 36 between the opposed peripheral walls 34c, and reciprocates the moving block 36 along the inner surface of the guide groove 34C.

  In the moving block 36 shown in the figure, the sliding portion 36A is an inclined surface 36a along the protruding inclined surface 32A. The moving block 36 slides the inclined surface 36a along the protruding inclined surface 32A of the pressing block portion 32 that reciprocates, thereby reciprocating the moving block 36 in the short direction of the base plate. Since the moving block 36 having this structure is slid while the inclined surface 36a is brought into contact with the protruding inclined surface 32A of the pressing block portion 32 in a wide area, the moving block 36 can be reliably moved along the protruding inclined surface 32A. is there. The moving block 36 shown in the figure has a sliding portion 36A as an inclined surface 36a and an outer shape of a single trapezoid. The moving block 36 slides two parallel sides of the trapezoidal shape along the peripheral wall 34c of the guide groove 34C so as to move toward or away from the opposite caster 1. However, the sliding portion may be a curved surface. The sliding portion can move the moving block while reducing the frictional resistance.

  Further, the moving block 36 includes a storage recess 36 </ b> B that stores a rear end portion of the projecting pin that enters and exits toward the caster 1. The housing recess 36 </ b> B is a groove-like recess having an opening in the direction of the caster 1 and is housed so that the rear end portion of the protruding pin 10 can reciprocate inside. The housing recess 36 </ b> B has a structure that can reciprocate by guiding the flange 10 </ b> B provided at the rear end of the protruding pin 10 to the inside.

  The protruding pin 10 is moved in and out toward the yoke 14 of the caster 1, more precisely, toward the vertical axis 12 that is the center of the yoke, so that the yoke 14 of the caster 1 stops in the stop direction, or The yoke 14 is in a moving state that does not stop. The protruding pin 10 has a shape having a flange portion 10B at the rear end of the elongated rod portion 10A. The protruding pin 10 has the rod portion 10A inserted through the through hole 24X of the fixed portion 24 and the rear end flange portion 10B inserted so as to be able to enter and exit the storage recess 36B of the moving block 36.

Thus, the yoke 14 is stopped in the stop direction. In a state where the rod portion 10A is retracted and the tip portion is pulled out from the locking recess 9 of the yoke 14, the yoke 14 of the caster 1 can be freely rotated without being stopped.

  The protruding pins 10 are arranged so that they can elastically enter and exit the fixing portion 24. In order to allow the protruding pin 10 to move in and out elastically, the flange portion 10 </ b> B of the protruding pin 10 is disposed in the storage recess 36 </ b> B of the moving block 36 via the pressing spring 37. The illustrated pressing spring 37 includes a first pressing spring 37 </ b> A and a second pressing spring 37 </ b> B disposed before and after the flange portion 10 </ b> B of the protruding pin 10.

The peripheral wall 34d opens a through hole (not shown) through which the protruding pin 10 passes. As shown in FIGS. 13 and 14, the first pressing spring 37 </ b> A is elastically deformed and elastically moves the tip of the rod portion 10 </ b> A toward the yoke 14 when the slide block 30 moves from the retracted position to the advanced position. To protrude. Further, as shown in FIG. 11, the first pressing spring 37 </ b> A is moved in a direction in which the protruding pin 10 is pulled in by elastically pressing the collar while the slide block 30 moves from the forward movement position to the backward movement position. .

  The second pressing spring 37B is disposed in the storage recess 36B of the moving block 36, and presses the protruding pin 10 in the pushing direction by bringing one end into contact with the bottom surface of the storage recess 36B and the other end in contact with the flange 10B. doing. As shown in FIGS. 13 and 14, the second pressing spring 37 </ b> A elastically moves the flange portion 10 </ b> B when the slide block 30 moves from the retracted position to the advanced position and the moving block 36 moves in the protruding direction. When the slide block 30 moves from the forward movement position to the backward movement position as shown in FIG. 11, the flange portion 10B pressed by the first pressing spring 37A is pressed. One end is pressed to the moving block 36 in the pulling direction.

  Further, in a state where the slide block 30 moves to the forward movement position and the moving block 36 moves in the protruding direction, the tip of the protruding pin 10 pushed out in the protruding direction is not guided to the locking recess 9 of the yoke 14, As shown in FIG. 13, in a state where the tip of the protruding pin 10 presses the outer peripheral surface of the yoke 14, the second pressing spring 37 </ b> B is elastically deformed so that the flange portion 10 </ b> B of the protruding pin 10 is accommodated in the housing recess of the moving block 36. 36B is elastically drawn into the interior of 36B. As shown in FIG. 14, the protruding pin 10 pushed toward the yoke 14 has the tip of the rod portion 10 </ b> A promptly moved in a state where the locking recess 9 of the yoke 14 is positioned opposite the tip of the rod portion 10 </ b> A. Guided by the locking recess 9, the yoke 14 is stopped at the stop position. However, the locking recess 9 provided in the yoke 14 of the caster 1 is not always present at the tip of the protruding rod portion 10A. At this time, the tip of the rod portion 10A pushed toward the yoke 14 abuts on the outer peripheral surface of the yoke 14 without being guided by the locking recess 9 as shown in FIG. Therefore, in this state, the protruding pin 10 does not protrude to the complete protruding position, and enters a standby state in which the rear end portion is stored in the storage recess 36 </ b> B of the moving block 36. In this state, when the yoke 14 of the caster 1 rotates and the locking recess 9 comes to a position facing the tip of the rod portion 10A, as shown in FIG. 14, the second pressing spring 37B is elastically pressed. The tip of the rod portion 10A of the protruding pin 10 is inserted into the locking recess 9 and the yoke 14 is stopped at the stop position.

  When the locking recess 9 is not located at the tip of the protruding pin 10 to be pushed out, as shown in FIG. 13, the tip surface of the protruding pin 10 presses the outer peripheral surface of the yoke 14. The rotation of is not stopped. However, as shown in FIG. 15, the caster 1 is in a state where it can be easily rotated around the lowest point U of the wheel 15 that contacts the ground 40. This is because, as indicated by the arrow A in the figure, the caster 1 swings and the yoke 14 rotates by moving the bag main body 3 slightly back and forth. Therefore, in the state where the stopper mechanism 5 is operated and the tip of the protruding pin 10 is not inserted into the locking recess 9 of the yoke 14 of any caster 1, as shown by the arrow A in the figure, the heel body 3 is slightly The yoke 14 of the caster 1 is rotated by moving the caster 1 back and forth, and the tip of the projecting pin 10 is inserted into the locking recess 9 of the yoke 14 so that the yoke 14 is locked. Can be stopped.

  The above pressing spring 37 makes the pressing force of the second pressing spring 37B larger than the pressing force of the first pressing spring 37A. As a result, when the moving block 36 is pressed by the pressing block 32 and protrudes, the protruding pin 10 is pushed out in the protruding direction, and the tip of the protruding pin 10 abuts on the outer peripheral surface of the yoke 14 so that the protruding pin 10 is moved. In a state where the protrusion pin 10 cannot be pushed out, the protrusion pin 10 is stopped at the contact position. Further, in a state where the tip of the protrusion pin 10 is located in the locking recess 9 of the yoke 14, the protrusion pin 10 is pushed out to the protrusion position. The tip of the rod portion 10A is inserted into the locking recess 9.

  In the above-described lock portion 8, the first pressing spring 37 </ b> A and the second pressing spring 37 </ b> B are arranged in a balanced manner as the pressing spring 37, but the pressing spring is not necessarily the first pressing spring and the second pressing spring 37 </ b> B. It is not necessary to have a pressing spring, and one pressing spring can be arranged in a balanced manner so that the above-described pressing state can be realized.

  The yoke 14 of the caster 1 is provided with a locking recess 9 into which the tip of the rod portion 10A of the protruding pin 10 is inserted on the outer peripheral surface. The locking recess 9 is provided at a position that faces the tip of the rod portion 10A and has a depth and shape that can guide the tip of the rod portion 10A and prevent the yoke 14 from rotating. The casters 1 at the four corners are provided with locking recesses 9 in the yokes 14 of the respective casters 1 so that the yokes 14 can be stopped in the stop directions shown in FIGS. 4 to 6 described above. The yoke 14 in the figure is provided with two locking recesses 9 located at both ends of the diameter of the yoke 14 so that the yoke 14 can be stopped in two stop directions different in direction by 180 degrees. Since the yoke 14 can guide the tip of the protruding pin 10 to any one of the locking recesses 9 in a state where the caster 1 is rotated halfway, the rotation of the caster 1 can be quickly stopped. However, the caster does not necessarily need to be provided with two locking recesses, and can be configured to be provided with one locking recess and stop in one stop direction.
