The shaft body 15 is raised in a direction substantially orthogonal to the one side wall surface portion which is a corner portion of the one side wall 7. That is, the axis of the shaft body 15 is along the thickness direction Z.

  The holding mechanism portion 13 includes a cam member 20 fixed to the outer peripheral portion of the shaft body 15 (or formed integrally with the outer peripheral portion of the shaft body 15). A plurality of cam pieces 21 are formed on the outer peripheral surface of the cam member 20 so as to be adjacent to each other in the circumferential direction. The cam piece 21 has a different diameter so that the circumferential surface of the cam piece 21 has a larger diameter from one circumferential side to the other circumferential side. In the present embodiment, a plurality of cam pieces 21 (six in this embodiment) are provided.

  Specifically, each cam piece 21 is sequentially curved while being curved from the minimum diameter end 21a to the maximum diameter end 21b, the minimum diameter end 21a being the one end in the circumferential direction, the maximum diameter end 21b being the other end in the circumferential direction. And a curved peripheral surface 21c whose diameter is enlarged. The cam pieces 21 adjacent in the circumferential direction are continuous via a stepped surface 21d connecting the minimum diameter end 21a and the maximum diameter end 21b. The cam pieces 21 may be adjacent to each other in the circumferential direction or may be separated from each other.

  The holding mechanism unit 13 includes a cylindrical member 22 that is disposed at a predetermined radial distance from the cam member 20. The cylindrical member 22 is concentric with the fixing member 18 and is formed integrally with the plate surface of the fixing member 18. The holding mechanism unit 13 includes a plurality of brake shoes 23 formed to have the same thickness in the radial direction, and rolling elements 24 having the same diameter. The brake shoe 23 and the rolling element 24 are located inward of the cylindrical member 22 in the radial direction, and are arranged in the order of the brake shoe 23 and the rolling element 24 from the radially outer side.

  In the present embodiment, the rolling elements 24 are rollers, and the number of rolling elements 24 matches the number of cam pieces 21. The rolling element 24 is held by a holder 25. The rolling elements 24 are arranged at predetermined intervals (fixed intervals) in the circumferential direction by the cage 25. The retainer 25 has a function of retaining the rolling element 24 so as to be movable in the radial direction and the outward direction. The cage 25 is fixed to, for example, the plate surfaces of the fixing members 18 and 18.

  Each rolling element 24 rotates in contact with the curved peripheral surface 21 c of the cam piece 21 by the rotation of the cam member 20. Specifically, each rolling element 24 is configured to rotate while moving radially inward and outward with the movement of the curved peripheral surface 21c of the cam piece 21 as the cam member 20 rotates.

  Each brake shoe 23 is formed in a circular arc shape. These brake shoes 23 are disposed between the rolling elements 24 and the inner peripheral surface 22 a of the cylindrical member 22. In the present embodiment, three brake shoes 23 are provided apart from each other in the circumferential direction. An inner peripheral surface 23 a of one brake shoe 23 is provided so as to contact the two rolling elements 24. When the rolling element 24 is on the minimum diameter end 21 a side (see FIG. 10A), a gap 26 is generated between the outer peripheral surface 23 b of the brake shoe 23 and the inner peripheral surface 22 a of the cylindrical member 22. When the rolling element 24 is on the maximum diameter end 21b side (see FIG. 10B), the gap 26 is eliminated, and the outer peripheral surface 23b of the brake shoe 23 and the inner peripheral surface 22a of the cylindrical member 22 are in pressure contact. A concave portion 27 that is concave outward in the radial direction is formed at the central portion in the circumferential direction of the inner peripheral surface 23a of each brake shoe 23 (see FIG. 9).

  The holding mechanism unit 13 includes a guide body 28 that guides each brake shoe 23 inward and outward in the radial direction. The guide body 28 includes a main body 29 formed in an annular shape so as to cover the rolling element 24 and the cylindrical member 22 from one side in the axial direction. The main body 29 is fixed to, for example, one end face in the axial direction of the cylindrical member 22.

  At the center in the radial direction of the main body 29, a hole 29a for projecting the end of the shaft body 15 is formed. A guide piece 30 is formed on a part of the plate surface of the main body 29 so as to be bent toward the concave portion 27 of each brake shoe 23. The guide piece 30 is a member that is inserted into the recess 27 of the brake shoe 23 and guides the movement of the brake shoe 23 in the radial direction inside and outside.

  A locking piece 32 for locking one end 31 a of a spring 31 described later is integrally formed on a part of the main body 29 in the circumferential direction. The locking piece 32 is formed so as to protrude further outward in the radial direction from the outer peripheral portion of the guide body 28.

  The holding mechanism unit 13 includes an operated body 17 for directly rotating the shaft body 15. The operated body 17 is formed in a plate shape. In this embodiment, the operated body 17 is formed in a triangular shape with chamfered corners. One vertex of the operated body 17 is fixed to the end of the shaft body 15 protruding from the hole 29 a of the main body 29 of the guide body 28. With this configuration, the shaft body 15 (cam member 20) can be rotated only by the rotation of the operated body 17. A locking hole 17 a for locking the other end 31 b of the spring 31 is formed at another vertex of the operated body 17.

  The holding mechanism unit 13 includes the spring 31. The spring 31 is a member for biasing the operated body 17 around the shaft body 15 toward one side in the circumferential direction. In this case, the one side in the circumferential direction is a direction in which the rolling element 24 is pressed radially outward by the cam member 20 (see FIG. 8A). The direction in which the rolling element 24 is pressed radially outward by the cam member 20, that is, the rolling element 24 is pressed radially outward on the maximum diameter end 21 b side of the cam piece 21, and the brake shoe is pressed by the rolling element 24. This is a direction in which the outer peripheral surface 23b of the brake shoe 23 is pressed against the inner peripheral surface 22a of the cylindrical member 22 so that the outer peripheral surface 23b is pressed radially outward and the gap 26 is eliminated. Hereinafter, a state in which the outer peripheral surface 23 b of the brake shoe 23 is pressed against the inner peripheral surface 22 a of the cylindrical member 22 is referred to as a locked state of the operated body 17.

  In the first embodiment, a kick spring is used as a kind of the spring 31. One end 31 a of the kick spring is locked to the locking piece 32 of the main body 29 of the guide body 28. The other end portion 31 b of the kick spring is locked in a locking hole 17 a at another vertex of the operated body 17. A middle portion of the kick spring is wound around the cylindrical member 22 so as to cover the cylindrical member 22. In the present embodiment, a pair of holding mechanism portions 13 as described above are provided.

  As shown in FIGS. 4 and 5, in the grip portion 3, a part of a substantially middle portion in the thickness direction Z is cut away to form an opening 3 a. The carry case 1 includes an operation unit 33 for releasing the locked state or returning the locked state. The operation unit 33 is provided in the grip unit 3. The operation unit 33 is disposed so as to be exposed to the opening 3a. The operation unit 33 is a member that is pressed by the finger of the user H.

  The release mechanism unit 14 is configured to operate in a direction in which the locked state of the operated body 17 is released at another vertex of the operated body 17. The release mechanism unit 14 is configured by a link mechanism. The release mechanism portion 14 is provided on the grip portion 3 and the support portion 4. The release mechanism portion 14 includes a swing operation rod 34 that is inserted through the rod-shaped member 41 of the support portion 4, and a swing rod (insulator member) 35 that is built in the grip portion 3.

  A bent piece 34 a that is bent in a direction perpendicular to the extending direction of the swing operation rod 34 is formed at each end of the swing operation rod 34. The bent piece 34 a is locked to an operation hole 17 b formed at another top portion of the operated body 17, and the swing operation rod 34 is pulled toward the grip portion 3 against the elasticity of the spring 31. As a result, the operated body 17 is configured to rotate in a direction in which the locked state is released. In other words, the cam piece 21 of the cam member 20 is configured to rotate in the circumferential direction toward the minimum diameter end 21a.

  The other end of the swing operation rod 34 is extended to the inside of the end of the grip portion 3. One end of the swing rod 35 is connected to the other end of the swing operation rod 34 via an end pin 35a. The swing rod 35 is arranged along the longitudinal direction (thickness direction Z) of the grip portion 3. The other end of the swing rod 35 is in contact with the operation unit 33 in the grip portion 3. A midway portion in the longitudinal direction of the swing rod 35 is supported by a midway pin 35b. With this configuration, the swing rod 35 can swing while being in contact with the operation portion 33 with the midway pin 35b as the swing center.

  The bent piece 34 a is locked in an operation hole 17 b formed at another top portion of the operated body 17, and the base end of the support portion 4 is fixed to the operated body 17. Therefore, the locked state is also the locked state of the support portion 4.

  In the carry case 1 having the above-described configuration, the user H presses the operation portion 33 to release the lock state (holding) of the support portion 4 around the shaft body 15 by the holding release mechanism portion 16, and the support portion 4 is pivoted. By rotating around the body 15, the grip 3 can be adjusted to a height that matches the body shape of the user H.

  More specifically, in the storage posture I in which the support portion 4 and the grip portion 3 are tilted along the upper wall surface of the frame wall 9 of the case body 2, the operated bodies 17 and 17 and the support portion 4 are It is locked. In this locked state, as shown in FIG. 10A, each rolling element 24 of the holding mechanism portion 13 is on the maximum diameter end 21 b side of the cam piece 21. That is, the brake shoe 23 is pressed against the inner peripheral surface 22 a of the cylindrical member 22 by the rolling element 24. The support portion 4 and the grip portion 3 are in the storage posture I. For this reason, the operated body 17 and the support portion 4 provided integrally with the operated body 17 cannot rotate to one side or the other side in the circumferential direction around the shaft body 15.

  Therefore, as shown in FIG. 5, the operation unit 33 is pressed and moved toward the inside of the gripping unit 3 from the state of FIG. 4 where the operation unit 33 is exposed to the opening 3 a by the operation of the finger of the user H. . At this time, at least a pressing force that resists the elasticity of the spring 31 is required. When the operating portion 33 is pressed and moved toward the inside of the grip portion 3, the swinging rods 35 and 35 that are in contact with the operating portion 33 rotate (swing) around the intermediate pin 35b. The swing operation rods 34, 34 connected to the swing rods 35, 35 via the end pin 35a are pulled forward. When it does so, the to-be-operated bodies 17 and 17 connected with the bending pieces 34a and 34a of the rocking | fluctuation operation rods 34 and 34 will rotate to the circumferential direction other side. Since the operated bodies 17 and 17 and the shaft body 15 are provided integrally, when the operated bodies 17 and 17 are rotated, the shaft body 15 is also rotated in the same direction and integrated with the shaft body 15. The cam member 20 and the cam piece 21 which are provided in the same direction rotate in the same direction.

  The rolling element 24 is rotatably held by a fixed holder 25. For this reason, even if the cam piece 21 rotates to the other side in the circumferential direction, the rolling element 24 does not move to the other side in the circumferential direction, and the cam piece 21 moves from the maximum diameter end 21b side to the rolling element 24. It moves to the small-diameter end 21a side, and the radially outward pressing force applied from the cam piece 21 to the rolling element 24 is released. Then, the pressure contact between the outer peripheral surface 23b of the brake shoe 23 and the inner peripheral surface 22a of the cylindrical member 22 that are in pressure contact with each other by the rolling elements 24 is released, and a gap 26 is generated. That is, the locked state is released.

  When the locked state is released, the support portion 4 and the grip portion 3 that are in the storage posture I can be rotated to one side in the circumferential direction around the shaft body 15. After releasing the locked state, the user H holds the holding portion 3 while turning the operating portion 33 while releasing the locked state, and rotates the support portion 4 to one side in the circumferential direction around the shaft body 15. Move. By the rotation of the support unit 4, the grip unit 3 changes from the storage posture I to the use posture U. The use posture U is a posture in which the grip portion 3 is raised from the storage posture I. In the use posture U with respect to the storage posture I, the grip portion 3 can take a stepless angle. The user H releases the pressing of the operation unit 33 by making the holding unit 3 easy to hold.

  When the pressing of the operating portion 33 is released, the operated body 17 is rotated to one side in the circumferential direction by the elastic restoring force of the spring 31, and the shaft body 15 and the cam member 20 are rotated to one side in the circumferential direction. Then, the maximum diameter end 21 b side of the cam piece 21 is positioned with respect to the rolling element 24 and pushes the rolling element 24 outward in the radial direction, so that the outer peripheral surface 23 b of the brake shoe 23 contacts the inner peripheral surface 22 a of the cylindrical member 22. Pressed. That is, the support part 4 will be in a locked state. On the other hand, when the operated bodies 17 and 17 are rotated to one side in the circumferential direction, the support portion 4 is pulled backward by the operated bodies 17 and 17, and when the support portion 4 is pulled rearward, The oscillating rods 35 and 35 rotate around the midway pin 35 b and maintain a contact state with the operation unit 33.

  If the user H wants to change the position of the grip part 3, if the user H presses the operation part 33 as described above, the locked state is released, so that the position of the grip part 3 can be further changed. Even when the grip portion 3 is returned to the storage posture I, if the user H presses the operation portion 33, the locked state is released, so that the use posture U can be returned to the storage posture I, and the grip portion 3 can be rotated. Is blocked.

  The user H sets the grip portion 3 to a desired height, and pulls the carry case 1 behind the user H, moves the carry case 1 along the side of the user H, or moves the user H It is a preference of the user H to move the carry case 1 by pushing it ahead.

  As shown in FIG. 3, when the road surface 5 is a staircase and the ascending staircase, the user H can move the case main body 2 so as to slide at the corner of the staircase. Even in this case, if the grip portion 3 is in the locked state, since the sliding member 12 is provided on the frame wall 9 in the case body 2, the carry case 1 needs to be lifted and moved so as not to be placed on the stairs. The carry case 1 can be moved easily.

  On the descending staircase, the user H can reverse the carry case 1 and move the case body 2 forward at the corner of the staircase. Even if it does in this way, since the sliding member 12 is provided in the frame wall 9 in the case body 2, it is not necessary to lift and move the carry case 1 so as not to be placed on the stairs, and the carry case 1 can be moved easily. Be made. On the flat road surface 5 as shown in the center of FIG. 3, the carry case 1 can also be moved by the user H holding the grip portion 3.

  By the way, in the carry case 1 in this embodiment, the shaft body 15 along the thickness direction Z is provided with a handle member constituted by the support portion 4 and the grip portion 3 in a direction orthogonal thereto. In other words, the carry case 1 can be used in such a form that it is not pushed or pulled with a force acting on one end side in the thickness direction Z but is pushed or pulled with a force acting on one end side in the front-rear direction Y. It is.

  When the user H applies a force to one end side in the thickness direction Z of the carry case 1 and pushes or pulls it in the front-rear direction Y, an unbalanced force acts on the carry case 1 in the thickness direction Z. For this reason, it is difficult for the user H to move the carry case 1. On the other hand, if the carry case 1 is pushed or pulled with a force acting on one end side in the front-rear direction Y, a force acts equally on the carry case 1 in the thickness direction Z. For this reason, the user H can move the carry case 1 stably. Moreover, in the present embodiment, the handle member can be rotated around the shaft body 15 along the thickness direction Z. For this reason, the grip part 3 can be set at a position where the user H can easily grip, and the carry case 1 can be moved more stably.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. The same applies to the specific configuration of each part, and the operational effects are not limited to the above description.

  In the above embodiment, the shaft body 15 is at each corner of the one side wall 7 and the other side wall 8, and an example is shown along the direction substantially orthogonal to the one side wall surface part and the other side wall surface part. However, if the shaft body 15 is located at the edge of the case body 2 and the user H can move the carry case 1 by gripping the grip portion 3, each of the one side wall 7 and the other side wall 8 is not necessarily used. There is no need to place them in the corners.

  For example, the shaft body 15 may be disposed at the middle of each of the one side wall 7 and the other side wall 8 in the vertical direction at the edge of the case body 2. In this case, in the storage posture, the support portion 4 is along the front wall surface or the rear wall surface of the case body 2. In the use posture, the support portion 4 rotates around the shaft body and is separated from the front wall surface or the rear wall surface. In addition, the shaft body 15 may be in the middle in the front-rear direction of the upper wall surface of the case body 2.

  The shaft body 15 may be in the middle of the thickness direction at the edge and corner of the case body 2. In this case, the shaft body 15 is closer to the center side in the thickness direction Z than the shaft body 15 of the carry case 1 of the first embodiment. Therefore, according to the position of the shaft body 15, the separation width of the support part 4 is narrower than that of the first embodiment.

  The pair of shaft bodies 15 may be arranged so as to approach one side or the other side in the thickness direction Z. By doing in this way, it becomes possible to divide the case main body 2 in the middle part in the thickness direction Z and along the front-rear direction Y. In this case, the carry case 1 is not limited to the configuration in which the side wall 7 is opened and closed by providing the slide fastener 10 on the wall surface of the side wall 7, but can be opened and closed by dividing the case body 2.

  In the first embodiment, the slide fastener 10 is provided only on the wall surface of the one side wall 7 so that the one side wall 7 can be opened and closed. However, the slide fastener 10 may be provided on the other side wall 8 to open and close the other side wall 8, for example. The opening / closing means is not limited to the slide fastener 10 and may be a hook-and-loop fastener or a dot button. Further, the means for opening and closing the case main body 2 may be configured to form an opening in the side wall and to provide a door that is rotatably attached to the opening via a hinge member.

  In 1st embodiment, the holding mechanism parts 13 and 13 showed the example provided in a pair so that it might arrange | position to the upper corner part of the one side wall 7 and the other side wall 8. As shown in FIG. The holding mechanisms 13 and 13 include the fixing members 18 and 18, the shaft body 15, the cam member 20, the rolling element 24, the brake shoe 23, the spring 31, the cylindrical member 22, the guide body 28, and the operated bodies 17 and 17.

However, in the carry case 1 of the present invention, the holding mechanism portions 13 and 13 are not provided as a pair, but a holding mechanism portion having a configuration excluding the shaft body 15 is provided on one side and a shaft body is provided on the other side. The support portion 4 can be connected to the shaft body.

  In each said embodiment, the shaft body 15 showed the example arrange | positioned in a pair at the edge. However, the shaft body 15 may not be provided separately in the thickness direction Z but may be a single configuration along the thickness direction Z. In the case of such a configuration, the support portions 4 and 4 may be provided alone without being provided in pairs. Furthermore, the carry case 1 of the present invention can be configured to extend and contract the support portions 4 and 4 using an expansion / contraction mechanism (for example, a telescopic type).

  In each said embodiment, the case main body 2 showed the example formed in the rectangular parallelepiped shape. However, the case main body 2 is not limited to a rectangular parallelepiped shape, and may be a three-dimensional shape having a roundness in consideration of functional aspects and design. Moreover, even if it is a rectangular parallelepiped shape, the front-back length may be formed long compared with the up-down length. In short, the carry case of the present invention only needs to have a configuration in which the shaft body is aligned in the thickness direction Z and the support portion is rotated around the shaft body. And it becomes easy to move a carry case notably by comprising in this way.

  In the carry case in each of the above embodiments, the case where the holding release mechanism portion 16 is provided is illustrated. However, the holding release mechanism portion 16 is not necessarily provided, and the carry case of the present invention includes a shaft body along the thickness direction Z of the case main body 2 at the edge of the case main body 2 and the support portion around the shaft body. It is only necessary that the gripping portion can be adjusted to a height or an angle that matches the user's body shape by rotating the handle to the position.

  In each said embodiment, the case where a pair of support parts 4 and 4 were formed in linear form without being bent was shown. However, as shown in the second embodiment in FIG. 11, the support portions 4, 4 can be configured to bend at substantially right angles in the middle in the longitudinal direction. In this case, the shaft body 15 is disposed in the middle in the up-down direction, which is a position lowered from the upper end of the edge of the case body 2. The support parts 4 and 4 include a shaft body side hook-like part 4A and a gripping part side hook-like part 4B. In the storage posture I, the shaft body side hook-shaped portion 4A extends along the vertical direction X in the upper portion of the case main body 2 with respect to the shaft body 15, and the grip portion side hook-shaped portion 4B extends along the front-back direction Y along the upper edge of the case main body 2. In the usage posture U, the shaft body side hook-shaped part 4A and the gripping part side hook-shaped part 4B are both separated from the case main body 2.

  By disposing the shaft body 15 at a position lower than the upper end of the edge of the case main body 2 in this manner, the shaft body 15 is more likely to carry the case than when the shaft body 15 is at the upper end of the edge of the case main body 2. It becomes close to the center of gravity of 1. For this reason, especially when a heavy object is accommodated in the case body 2, the carry case 1 can be easily carried.
