Therefore, the sliding members 12 may be referred to as protectors or protect bars.

  • the supporting parts 4 are configured to be telescopic so as to be freely expanded and contracted in the up-down direction by telescopic mechanisms (not shown).
  • the pivoting disk 14 is formed integrally with the proximal ends of the supporting parts 4.
  • the pivoting disk 14 is a part that supports the supporting parts 4 pivotally about a shaft center 15 extending along the thickness direction Z.
  • the pivoting disk 14 is externally fitted to a fixing part that constitutes parts of holding and releasing mechanisms 16, which will be described below, pivotally about the shaft center 15 via a bearing 17 (for example, a slip bearing is used therefor).
  • the shaft center 15 is located, on the outer surface of the second sidewall 8, substantially at the center in the front-rear direction and on the lower side of the center in the up-down direction.
  • the pivoting disk 14 is made of metal such as aluminum.

  • the holding and releasing mechanisms 16 include a disk-shaped side shaft (corresponding to the shaft) 18 as the fixing part, an operating rod 19, an operating part 20 configured to operate the operating rod 19 to move (operate the holding and releasing mechanisms 16 to hold and release the proximal ends of the supporting parts 4), and advancing and retracting mechanisms 23 including advancing and retracting members 22 configured to be advanced into and retracted from holding holes 21, which will be described below, by the movement of the operating rod 19.
  • the side shaft 18 includes a flat disk-shaped part 24, and a flat columnar shaft part 25 projecting outwardly in the thickness direction from the center of the disk-shaped part 24.
  • the center of the side shaft 18 is fixed to the outer surface of the second sidewall 8 so as to coincide with the shaft center 15 by a fixing means such as a bolt 26.

  • the holding holes 21 are formed at equal intervals in the circumferential direction throughout the entire region on the surface on the outer circumferential side of the disk-shaped part 24.
  • the holding holes 21 may pass through the disk-shaped part 24, or may be formed without passing therethrough.
  • the holding holes 21 pass through the disk-shaped part 24 in the thickness direction Z, and twenty-four holding holes 21 are formed.
  • the number of the holding holes 21 is twenty-four in this embodiment, the number of the holding holes 21 may be more than twenty-four, or less than twenty-four, as long as they allow the pivoting part 13 to tilt (pivot) in the front-rear direction Y within a specific range.
  • the operating rod 19 is internally provided throughout substantially the entire region of the internal spaces of the carrying grip 3 and the supporting parts 4, and includes a transverse rod 27 provided inside the carrying grip 3 and longitudinal rods 28 extending downward respectively from the front and rear ends of the transverse rod 27. Further, an opening 29 is formed on the top surface in the middle in the front-rear direction of the carrying grip 3, where the operating part 20 with which the user H presses the transverse rod 27 downward is formed integrally with the transverse rod 27, and the operating part 20 is exposed through the opening 29. That is, the operating part 20 is provided in the carrying grip 3.
  • Pressing members 30 configured to directly press the advancing and retracting members 22 of the advancing and retracting mechanisms 23 are attached to the lower ends of the longitudinal rods 28.
  • Each of the pressing members 30 has a substantially prismatic shape with its longitudinal direction extending in the up-down direction, and has a lower end at which a pressing inclined surface 31 is formed.
  • a flange-shaped limitation member 32 that limits the amount of movement of the pressing member 30 in the up-down direction (in this case, downward) is formed in an upper part of the pressing member 30.
  • the pressing inclined surface 31 is inclined in a direction such that the disk-shaped part 24 side that is a first side in the thickness direction Z is lower than a second side in the thickness direction Z.
  • each of the advancing and retracting mechanisms 23 is arranged inside a supporting part 4.
  • the advancing and retracting mechanism 23 includes an outer housing 33 whose longitudinal direction extends in the thickness direction Z, the advancing and retracting member 22 provided inside the outer housing 33 so as to be movable in the thickness direction Z, and a spring 34 biasing the advancing and retracting member 22 in the thickness direction Z and biasing a longitudinal rod 28 upward.
  • the outer housing 33 is hollow and is fixed to the inside of the supporting part 4 so as to extend in the thickness direction Z across the supporting part 4.
  • a stopper 33a that can abut against the limitation member 32 is formed so as to project upward, in an upper part substantially at the center in the thickness direction Z of the outer housing 33.
  • the stopper 33a for example, has a rectangular cylindrical shape, into which the pressing member 30 is fitted on a constant basis, thereby guiding the pressing member 30 in the up-down direction X.
  • the advancing and retracting member 22 includes a projection 36 that is freely advanced into and retracted from (inserted into and removed from) a holding hole 21 at its distal end (on the disk-shaped part 24 side that is the first side in the thickness direction Z). Accordingly, an insertion hole 37 through which the projection 36 is inserted is formed in the supporting part 4. Further, a part of the pressing member 30 including a lower part of the pressing inclined surface 31 enters the advancing and retracting member 22. This part is configured as a locking part 30a that can be locked to the inner surface of the upper wall of the outer housing 33.
  • the advancing and retracting member 22 includes, at its proximal end, an operated part 38 against which the pressing inclined surface 31 abuts on a constant basis. A surface of the operated part 38 in contact with the pressing inclined surface 31 is in the form of an inclined surface that is inclined in the same direction as the pressing inclined surface 31.
  • the spring 34 is a coil spring in this embodiment, and is arranged inside the outer housing 33 on the second side in the thickness direction Z of the advancing and retracting member 22 so as to bias the advancing and retracting member 22 toward the disk-shaped part 24 side.
  • a guide rod 39 inserted along the axis direction of the spring 34 is formed in the advancing and retracting member 22, and a guide hole 40 into which a part of the guide rod 39 on the second side can be inserted is formed on a sidewall of the outer housing 33 on the second side.
  • the advancing and retracting members 22 are biased in the thickness direction Z due to the elasticity of springs 34 of the advancing and retracting mechanisms 23, thereby allowing projections 36 to project into the holding holes 21. More specifically, the advancing and retracting members 22 are biased in the thickness direction Z due to the elasticity of the springs 34 of the advancing and retracting mechanisms 23 provided respectively in the supporting parts 4, thereby allowing the projections 36 to project into the holding holes 21 that are spaced farthest from each other. That is, the pivoting part 13 is held in a non-rotatable state about the shaft center 15.
  • the user H presses the operating part 20 downwardly against the elasticity of the springs 34.
  • the operating part 20 is pressed to move downwardly, to the extent of which the transverse rod 27 and the longitudinal rods 28 move downwardly, particularly, the longitudinal rods 28 move downwardly, thereby causing the locking parts 30a to press the operated parts 38 via their inclined surfaces toward the second side in the thickness direction Z.
  • the springs 34 are contracted. This causes the advancing and retracting members 22 to move toward the second side in the thickness direction Z. Accordingly, the projections 36 escape from the holding holes 21. Then, parts of guide rods 39 enter guide holes 40.
  • the pivoting part 13 When the projections 36 escape from the holding holes 21, the pivoting part 13 is free to pivot about the shaft center 15. Then, the user H pivots the pivoting part 13 about the shaft center 15 at a preferred angle (angle suitable for the body shape of the user H). At this time, the side shaft 18 is fixed to the second sidewall 8 so as not to pivot, whereas the pivoting disk 14 of the pivoting part 13 pivots about the shaft part 25.
  • the springs 34 are elastically restored, and the advancing and retracting members 22 move toward the first side in the thickness direction Z, so that the projections 36 of the advancing and retracting members 22 are inserted into the holding holes 21 at positions corresponding to the preferred angle of the user H. This allows the position of the pivoting part 13 about the shaft center 15 to be held (see the imaginary lines in Fig. 1 ).
  • the holding holes 21 are formed at equal intervals in the circumferential direction throughout the entire region on the outer circumferential surface of the disk-shaped part 24. Therefore, the pivoting part 13 can pivot 360° about the shaft center 15.
  • the pivoting part 13 may be pivoted as shown by the imaginary line on the left side in Fig. 1 , supposing that the right side of Fig. 1 is the front side.
  • the shaft center 15 is located, on the outer surface of the second sidewall 8, substantially at the center in the front-rear direction and on the lower side of the center in the up-down direction. Therefore, the position on which the force for moving the carrying case 1 acts can be located on the lower side of the case body 2, and thus the case body 2 can be moved in a stable state.
  • the user H can move the case body 2 by pivoting the pivoting part 13 and by sliding the case body 2 at the corners of the steps. Since the case body 2 is provided with the sliding members 12 on the frame wall 9, there is no need to carry the carrying case 1 by lifting it up so as not to be in contact with the steps. Therefore, the carrying case 1 can be easily moved also in this way.
  • the pivoting part 13 is pivoted in the opposite direction to the direction in the case of the ascending steps.
  • the case body 2 is provided with the sliding members 12 on the frame wall 9, there is no need to carry the carrying case 1 by lifting it up so as not to be in contact with the steps. Therefore, the carrying case 1 can be easily moved also in this way.
  • the carrying case 1 can be moved also by gripping the handle 11.
  • the carrying case 1 according to the present invention is not limited to the aforementioned embodiment, and various modifications can be made without departing from the gist of the present invention.
  • the holding and releasing mechanisms 16 configured to hold the pivoting part 13 by the projections 36 projecting into two of the holding holes 21 that are spaced farthest from each other are described.
  • the projections 36 may be inserted into and removed from two of the holding holes 21 other than those spaced farthest from each other by reducing the distance between the supporting parts 4 in the front-rear direction Y.
  • the two of the holding holes 21 other than those spaced farthest from each other may be on the upper side of the shaft center 15, or may be on the lower side thereof, in the state where the pivoting part 13 is kept upright.
  • the case body 2 can be moved in a stable state. Therefore, the two of the holding holes 21 other than those spaced farthest from each other are preferably located on the lower side of the shaft center 15.
  • the carrying case 1 configured as above has a configuration such that the holding holes 21 are each formed so as to extend along the thickness direction Z, and the projections 36 are advanced into and retracted from the holding holes 21 in the thickness direction Z.
