Description

Container attaching / detaching mechanism and functional member for container attaching / detaching mechanism

[0001] The present invention relates to a container attaching / detaching mechanism and a functional member for a container attaching / detaching mechanism that attach a container (such as a pouch) capable of storing small items to, for example, a strap of a rucksack.

[0002] Conventionally, in order to attach a container (such as a pouch) capable of storing small items to, for example, a strap of a rucksack that is an attachment target, the container is sometimes hung using an annular member such as a carabiner.

[0003] However, when the container is hung using an annular member such as a carabiner, the container swings when the user walks, which may make the user feel annoyed.

[0004] Therefore, an object of the present invention is to provide a container attaching / detaching mechanism and a functional member for a container attaching / detaching mechanism that enable reliable attachment of a container while allowing the container to be attached to and detached from an attachment target.

[0005] The present invention is a container attaching / detaching mechanism that enables a container capable of storing articles to be attached to and detached from an attachment target, comprising: the container; a base portion that is inseparably attached to the container; and an attachment portion that is attachable to and detachable from the base portion, and is capable of attaching the container to the attachment target in a position-held state via the base portion.

[0006] The present invention also provides a functional member for a container attaching / detaching mechanism provided on a container capable of storing articles to enable the container to be attached to and detached from an attachment target, comprising: a base portion that can be inseparably attached to the container; and an attachment portion that is attachable to and detachable from the base portion, and is capable of attaching the base portion to the attachment target in a position-held state.

[0007] According to the above-mentioned present invention, the container can be attached with the attachment portion to the attachment target in a position-held state, so the container can be attached to the attachment target in a stable state. In addition, since the attachment portion can be attached to and detached from the base portion, the container can also be in a state without the attachment portion.

[0008] In the present invention, the mounting portion can also be a clip portion that is detachable from the base portion and can be attached to the object to be mounted while holding the container in position with respect to the object via the base portion by clamping with spring force.

[0009] According to the present invention described above, the mounting portion is a clip portion, and the container can be attached while the clip portion is held in position relative to the object to be attached by clamping with spring force applied, so that the container can be attached to the object in a stable state. Furthermore, since the clip portion is detachable from the base portion, the container can also be used without the clip portion.

[0010] The present invention provides a coupling means extending from the base portion to the mounting portion, the coupling means having a first portion provided on one of the base portion and the mounting portion, and a second portion provided on the other of the base portion and the mounting portion, the first portion and the second portion can be changed between a coupled state in which they are engaged with each other and a discoupled state in which they are not engaged.

[0011] According to the present invention described above, the coupling means extending from the base portion to the mounting portion comprises a first portion and a second portion, and the coupling means can be in a coupled state in which the first portion and the second portion are engaged with each other, or in a discoupled state in which they are not engaged.

[0012] In the present invention, the first part and the second part may change between the coupled state and the uncoupled state by sliding movement, and the coupled state may be maintained by fitting in a direction intersecting the direction of the sliding movement.

[0013] According to the present invention described above, the sliding movement of the first part and the second part changes the connection state between the base part and the mounting part, and even if the container attachment / detachment mechanism is subjected to an external force, the connection state can be maintained, and it is also possible to set it to a disconnected state where it is not engaged.

[0014] In the present invention, a coupling means is provided that extends from the base portion to the mounting portion, and the coupling means has a first portion provided on one of the base portion and the mounting portion, and a second portion provided on the other of the base portion and the mounting portion, and the first portion and the second portion change between a coupled state in which they are engaged with each other and a disengaged state in which they are not engaged by sliding movement, and the direction of the sliding movement may intersect with the direction connecting the portion that opens and closes when clamping in the clip portion and the opening and closing center of the clip portion.

[0015] According to the present invention described above, the coupling means is less affected by opening and closing operations on the object to which the clip portion is attached.

[0016] The present invention provides a coupling means extending from the base portion to the mounting portion, wherein the coupling means has a first portion provided on one of the base portion and the mounting portion, and a second portion provided on the other of the base portion and the mounting portion, wherein the first portion and the second portion change between a coupled state in which they are engaged with each other and a disengaged state in which they are not engaged by sliding movement, and the direction of the sliding movement can also be made parallel to the direction connecting the portion that opens and closes when clamping in the clip portion and the opening and closing center of the clip portion.

[0017] According to the present invention described above, the coupling means is less affected by opening and closing operations on the object to which the clip portion is attached.

[0018] The present invention provides a container attachment / detachment mechanism according to claim 4, wherein the attachment portion comprises a fitting portion that engages the first portion and the second portion, and a release operation portion that is operated when releasing the fitting.

[0019] According to the present invention described above, the fitted state can be maintained until the release operation part is operated.

[0020] In the present invention, the mounting portion is a clip portion that is detachable from the base portion and can be attached to the container via the base portion while maintaining its position relative to the object to be attached by clamping with spring force, and the release operation portion may be positioned away from the portion that is clamped by the clip portion.

[0021] According to the present invention described above, it is possible to prevent the release mechanism from being accidentally operated during opening and closing operations.

[0022] According to the present invention, since the mounting portion can be attached to the object to be attached while the container is held in position, the container can be attached to the object to be attached in a stable manner. Furthermore, since the mounting portion is detachable from the base portion, the container can be left without the mounting portion. Thus, the present invention provides a container attachment / detachment mechanism and a functional component for the container attachment / detachment mechanism that allows the container to be securely attached to the object to be attached while being detachable. The object, features, aspects, and advantages of the present invention will become clearer from the following detailed description and accompanying drawings.

[0023] This is a perspective view showing the container attachment / detachment mechanism according to one embodiment of the present invention in use. This is a rear view of the base portion sewn onto the container. This is a left side view of the base portion. This is a top view of the base portion. This is a top view of the clip portion. This is a front view of the clip portion. This is a rear view of the clip portion.

[0024] The following describes a container attachment / detachment mechanism according to one embodiment of the present invention. The container attachment / detachment mechanism is a mechanism that allows a container capable of storing an article to be attached to and detached from an object to which it is attached. In this embodiment, the article is a mobile phone such as a smartphone, the container is a pouch capable of storing the mobile phone, and the object to which it is attached is a backpack strap. In this embodiment, the overall vertical direction is defined with the user wearing the backpack.

[0025] The container attachment / detachment mechanism 1 will be explained with reference to Figures 1 to 7. As shown in Figure 1, the container attachment / detachment mechanism 1 includes a container 2, a base portion 3, and a clip portion S.

[0026] As shown in Figure 1, the container 2 is formed with a bottom and has an opening 2a on its top surface. It comprises a front surface 2b, a back surface 2c opposite the front surface 2b, two side surfaces 2d and 2f continuous with the front surface 2b and back surface 2c, and a bottom surface 2g continuous with the front surface 2b, back surface 2c, and both side surfaces 2d and 2f. A mobile phone can be placed inside the container 2 through the opening 2a.

[0027] Next, the base portion 3 will be described. As shown in Figure 2, the base portion 3 is positioned on the back surface 2c of the container 2. The base portion 3 comprises a sewn portion 4 that is sewn to the back surface 2c of the container, a base portion 5 that protrudes from the sewn portion 4, and a connecting projection 6 that further protrudes from the base portion 5. The base portion 3 is made of synthetic resin, the sewn portion 4 is made of a flexible synthetic resin, and the base portion 5 and the connecting projection 6 are made of a hard synthetic resin.

[0028] The area of ​​the back surface 2c of the container is larger than the area of ​​the stitched portion 4. The stitched portion 4 is a thin, rectangular plate-like member shaped vertically, with all four sides of the rectangle stitched to the back surface 2c of the container 2. In other words, the base portion 3 is fixed to the back surface 2c of the container 2 by stitching (stitching 4d) the stitched portion 4, making it impossible to separate. For this reason, the stitching 4d portion of the stitched portion 4 is made of a material and shape (thickness) that allows a needle to pass through for stitching. The stitched portion 4 is also stitched to the back surface 2c of the container with its center in the left-right direction. The upper end surface 4a of the stitched portion 4 is formed parallel to the opening 2a of the container 2, the side end surfaces 4b of the stitched portion 4 are formed parallel to the side surfaces 2d and 2f of the container 2, and the lower end surface 4c of the stitched portion 4 is positioned parallel to the bottom surface 2g of the container 2.

[0029] The base portion 5 protrudes from the sewing portion 4, leaving the four sides of the sewing portion 4 around its perimeter, and is formed in a rectangular shape that is reduced in size relative to the outer shape of the sewing portion 4. However, the base portion 5 is formed to be thicker than the sewing portion 4.

[0030] The connecting projection 6 is formed to protrude from approximately the center of the base 5 in both the left-right and up-down directions. The side of the connecting projection 6 that attaches to the base 5 is formed as a small, approximately rectangular surface, and the protruding side is formed as an approximately rectangular surface with progressively larger areas. Overall, the connecting projection 6 is formed as an approximately rectangular parallelepiped shape, with the left-right direction at the bottom being reduced in size.

[0031] More specifically, the connecting projection 6, as shown in Figures 3 and 4, has a convex upper inclined surface 6a, a convex lower inclined surface 6b, and convex left and right inclined surfaces 6c and 6d that protrude from the base 5, and a connecting projection 6e. Between the convex upper inclined surface 6a and the convex lower inclined surface 6b, the left and right width of the convex lower inclined surface 6b is progressively shorter than the left and right width of the convex upper inclined surface 6a. In other words, the connecting projection 6 is set to have a shorter left and right width as it goes downwards. The connecting projection 6e is a surface that is continuous with the front ends of the convex upper inclined surface 6a, the convex lower inclined surface 6b, and the convex left and right inclined surfaces 6c and 6d, and is parallel to the surface of the base 5. Although the upper edge of the connecting projection 6e is formed parallel to the upper edge 4a of the stitching portion 4, the lower edge of the connecting projection 6e is formed curved so that the center in the left and right direction is convex downwards. Therefore, the convex lower inclined surface 6b is inclined toward the base 5 in accordance with the curved state of the connecting projection 6e. Furthermore, the connecting projection 6 (the surface on which the connecting projection 6e is formed) is set to be larger than the thickness of the base 5.

[0032] Next, the clip portion S will be described with reference to Figures 1, 5 to 7. The clip portion S corresponds to the mounting portion. The clip portion S is formed separately from the base portion 3 and is provided so as to be positioned opposite to the container 2 when it is attached. In this embodiment, the clip portion S comprises a clamping plate portion 7, an opposing plate portion 8, a spring mechanism 9, and a contact body 10. Such a clip portion S is held on the strap 12 of a strap-shaped backpack 11, and the clamping plate portion 7 and the opposing plate portion 8 are separated relative to each other against the elasticity of the spring mechanism 9, and then the strap 12 is clamped, held by the contact body 10, and attached to the strap 12.

[0033] The clamping plate portion 7 is positioned on the back side of the strap 12 when the clip portion S is positioned on the strap 12 of the backpack 11. The clamping plate portion 7 is a plate-shaped member having a predetermined thickness. That is, as shown in Figure 5, the clamping plate portion 7 is formed in a plate shape from a clamping front surface 13 attached to the back of the strap 12, a clamping rear surface 14, and clamping side surfaces 15 surrounding the clamping front surface 13 and the clamping rear surface 14.

[0034] The opposing plate portion 8 is positioned to face the front side via the strap 12, with the clamping plate portion 7 positioned on the back side of the strap 12 of the backpack 11. The opposing plate portion 8 is a curved plate-shaped member having a predetermined thickness. Specifically, the opposing plate portion 8 is formed in a plate shape from an opposing rear surface 16 positioned on the base portion 3 side, an opposing front surface 17 attached to the front of the strap 12, and opposing side surfaces 18 surrounding the opposing rear surface 16 and the opposing front surface 17. Of the opposing side surfaces 18, the right opposing side surface 18 shown in Figure 6 (hereinafter referred to as the specific opposing side surface 18a) is inclined to widen toward the clamping front surface 13 side of the clamping plate portion 7. Furthermore, as mentioned above, while the clamping plate portion 7 is formed from a simple plate-shaped member, as shown in Figure 5, the opposing plate portion 8 is formed in a curved shape in the left-right center of the clamping plate portion 7.

[0035] The opposing front surface 17 and opposing side surface 18 have coupling recesses 19 that can be coupled (fitted) to coupling protrusions 6. The coupling protrusions 6 and coupling recesses 19 are coupled relatively detachably in the vertical direction. In this case, the coupling protrusions 6 and coupling recesses 19 are coupled detachably by sliding movement. Therefore, the coupling protrusions 6 and coupling recesses 19 serve as coupling means in the container attachment / detachment mechanism 1, extending from the base portion 3 to the clip portion S, with the coupling protrusions 6 provided on the base portion 3 being the first part and the coupling recesses 19 provided on the clip portion S being the second part.

[0036] The connecting recess 19 is a groove having an outer shape corresponding to the connecting protrusion 6, and is located on the other side of the opposing plate portion 8, that is, on the specific opposing side surface 18a side. The connecting recess 19 is located within the opposing front surface 17 and the upper opposing side surface 18, and as shown in Figures 5 and 6, it has a bottom surface 19a, and the thickness of the connecting recess 19 from the bottom surface 19a is the same as the thickness of the connecting protrusion 6e from the surface of the base portion 5. Furthermore, the connecting recess 19 is formed to extend from the upper opposing side surface 18 to the lower opposing side surface 18, and has a concave downward inclined surface 19b that faces the convex downward inclined surface 6b in the vertical direction, and concave left and right inclined surfaces 19c and 19d that face the convex left and right inclined surfaces 6c and 6d in the left and right direction. The inclination of the concave downward inclined surface 19b is the same as that of the convex downward inclined surface 6b, and the inclination of the concave left and right inclined surfaces 19c and 19d is the same as that of the convex left and right inclined surfaces 6c and 6d. Furthermore, the vertical height of the connecting recess 19 is the same as the vertical height of the connecting protrusion 6. In this way, the end of the connecting recess 19 is blocked by the recessed downward inclined surface 19b, and the end opposite the recessed downward inclined surface 19b is open.

[0037] In the base portion 3 and the clip portion S, a fitting means 20 is provided to ensure secure fitting between the connecting projection 6 and the connecting recess 19. This fitting means 20 has a receiving portion provided on the connecting projection 6 and a fitting portion provided on the connecting recess 19.

[0038] The fitting means 20 will now be described in detail. In this case, the fitted portion is provided on the base portion 3 and on the connecting convex surface 6e and the convex right-sloping surface 6d of the connecting convex portion 6. Specifically, as shown in Figure 2, the fitted portion is a groove 21 formed on the connecting convex portion 6. This groove 21 is formed midway in the height direction of the connecting convex surface 6e and the convex right-sloping surface 6d, has a constant groove width in the vertical direction, and is formed to have a predetermined thickness toward the base portion 5.

[0039] The fitting portion will now be described. As a prerequisite, the rod-shaped portion 22 provided on the clip portion S will be described. The rod-shaped portion 22 is arranged on the opposing plate portion 8 of the clip portion S, and the rod-shaped portion 22 has a rod-shaped portion body 22A that is movable in the left-right direction. The rod-shaped portion body 22A is formed by cutting out the bottom surface 19a of the coupling recess 19 in the vertical direction, and by cutting out the inside of the other side of the opposing plate portion 8 adjacent to the coupling recess 19 in the vertical direction. The fitting portion is a fitting piece 23 integrally formed on one side of the rod-shaped portion body 22A. Therefore, the fitting piece 23 is movable in the left-right direction, and the movement of the fitting piece 23 moves the rod-shaped portion 22. The fitting piece 23 is provided to fit the coupling projection 6 provided on the base portion 3 and the coupling recess 19 provided on the clip portion S. Furthermore, the rod-shaped portion 22 integrally includes a pressing piece 24 formed on the other side of the rod-shaped portion body 22A. The pressing piece 24 is operated when releasing the fitting.

[0040] The fitting piece 23 is formed to be fitted into the groove 21. The pressing piece 24 is capable of moving the rod-shaped body 22A in the left-right direction and is capable of protruding from a specific opposing side surface 18a. The rod-shaped part 22 is pressed to the other side by the elasticity of a spring (not shown) positioned on one side of the opposing plate part 8, and the outer circumference 23a of the fitting piece 23 protrudes from the concave left-sloping surface 19c of the coupling recess 19 due to the elasticity of the spring. Also, the pressing piece 24 protrudes from the specific opposing side surface 18a due to the elasticity of the spring. The rod-shaped part 22 is slidable relative to the opposing plate part 8 between a normal position in which the fitting piece 23 protrudes from the concave left-sloping surface 19c of the coupling recess 19 and the pressing piece 24 protrudes from the specific opposing side surface 18a due to the elasticity of the spring, and a release position in which the pressing piece 24 is pushed to the left against the elasticity of the spring. The rod-shaped portion 22 is located on the opposite side of the pivot shaft 26 from the part that is operated for opening and closing when the strap 12 of the backpack 11 is clamped by the clip portion S, that is, on the other side of the opposing plate portion 8.

[0041] To put the normal position and the released position in other words, the normal position is a state in which the connecting projection 6 is not fitted into the connecting recess 19, or a state in which the connecting projection 6 is fitted into the connecting recess 19 and the fitting piece 23 is fitted into the groove 21. The released position is a state in which, from the normal position in which the connecting projection 6 is fitted into the connecting recess 19 and the fitting piece 23 is fitted into the groove 21, the fitting piece 23 separates from the groove 21 as the pressing piece 24 is pressed against the opposing plate portion 8 (specific opposing side surface 18a). Therefore, the pressing piece 24 has the function of performing a release operation to move from the normal position to the released position, and can therefore be called a release operation part, and the pressing piece 24 releases the fitted state of the connecting projection 6 and the connecting recess 19. The pressing piece 24 is located in front of the part that is clamped during the operation of opening and closing when clamping by the clip portion S.

[0042] The spring mechanism 9 will now be described. The spring mechanism 9 uses spring force to bring the other sides of the clamping plate portion 7 and the opposing plate portion 8 closer together, and the clamping of the clamping plate portion 7 and the opposing plate portion 8, under the applied spring force, holds the container 2 in place relative to the strap 12 of the backpack 11 via the base portion 3.

[0043] As shown in Figure 5, the spring mechanism 9 consists of support parts 9A and 9B positioned and held on the clamping front surface 13 and opposing rear surface 16 of one side of the clamping plate portion 7 and the opposing plate portion 8, and a spring 25 positioned between the support parts 9A and 9B. The support parts 9A and 9B are formed in pairs with a gap between them in the height direction and are formed in a substantially triangular shape. A support shaft 26 is positioned vertically at the vertex of the substantially triangular shape. A kick spring is used as the spring 25, and the support shaft 26 passes through the wound portion of the spring 25, with the spring ends 25a and 25b in contact with the clamping front surface 13 and opposing rear surface 16 of one side of the clamping plate portion 7 and the opposing plate portion 8.

[0044] The contact body 10 will now be described. When the clip portion S clamps the strap 12, the contact body 10 is arranged as an anti-slip member on the inner surfaces of the opening and closing portions of the sandwiching plate portion 7 and the opposing plate portion 8. The contact body 10 is formed of a contact body main body 27 and a blade portion 28. The contact body main body 27 is arranged on the sandwiching front surface 13 between the other sides of the sandwiching plate portion 7 and the opposing plate portion 8 and on the opposing rear surface 16 side, extends in the left-right direction, and is formed so as to extend in the height direction of the sandwiching plate portion 7 and the opposing plate portion 8. The blade portion 28 is formed on the inner surface of the contact body main body 27, is formed in a sawtooth shape in a plan view, and is formed continuously across the height direction and in the left-right direction. Among the blade portions 28 provided on the sandwiching plate portion 7 and the opposing plate portion 8, part of the blade portion 28 on the other side is formed so as to mesh with each other by the spring force of the spring 25.

[0045] The container attaching / detaching mechanism 1 having the above structure includes a base portion 3 and a clip portion S, and is used such that the base portion 3 and the clip portion S are relatively coupled (fitted) in the vertical direction. Here, as an example, a description will be given of a mode where for a user U who uses the container attaching / detaching mechanism 1 of the present embodiment, the clip portion S is attached to the left strap 12 of a rucksack 11, and the base portion 3 is coupled to the clip portion S from above.

[0046] In a normal state (a state where the clip portion S is not attached to the strap 12), due to the elasticity of the spring 25 of the spring mechanism 9, the sandwiching plate portion 7 and the opposing plate portion 8 are in a closed state centering on the support shaft 26, and the clip portion S is formed such that part of the blade portion 28 of the contact body 10 meshes. To attach the clip portion S to the strap 12 from this normal state, one side of the sandwiching plate portion 7 and the opposing plate portion 8 is brought closer with the fingers (fingers on the right side) of the user U against the elasticity of the spring 25, thereby separating the blade portions 28 of the contact body 10 from each other.

[0047] In this state, in the clip portion S, the clamping front surface 13 of the clamping plate portion 7 is attached to the back surface of the strap 12, and the opposing rear surface 16 of the opposing plate portion 8 is attached to the front surface of the strap 12, then a user U releases the clip portion S from their finger. At this time, it is preferable that the clip portion S is horizontally attached to the strap 12. The portion that opens and closes when the clip portion S clamps is the blade portion 28 on one side of the clamping plate portion 7 and the opposing plate portion 8 among the blade portions 28 of both contact bodies 10. When the fingers are released from the clamping plate portion 7 and the opposing plate portion 8, both blade portions 28 bite into the surface of the strap 12, and the clip portion S is held on the strap 12.

[0048] Further, in this state, the recessed inclined surface 19b is located on the lower side in the coupling recess 19, the open side of the coupling recess 19 is located on the upper side, and the coupling recess 19 is oriented in the vertical direction with respect to the strap 12. Then, when the user U releases their finger, the strap 12 returns to a state close to a normal state. At this time, in the clip portion S, due to the elasticity of the spring 25, the blade portion 28 on the clamping plate portion 7 side abuts against the back surface of the strap 12, and the blade portion 28 of the opposing plate portion 8 abuts against the front surface of the strap 12. Then, the clip portion S, to which the elasticity of the spring 25 is applied, clamps the strap 12, so that the clip portion S is positionally held and attached to the strap 12. In addition, the vertical position of the clip portion S relative to the strap 12 depends on the preference of the user U. However, the vertical position of the clip portion S is also determined depending on the balance with the container 2 described later.

[0049] Furthermore, the convex lower inclined surface 6b of the coupling convex portion 6 is inclined toward the base portion 5 along the curved state of the coupling convex surface 6e. According to this configuration, it is easy to attach the coupling convex portion 6 to the coupling recess 19 of the clip portion S, and since it is formed in a curved state, it is less likely to catch compared to a shape with corners.

[0050] Incidentally, the clip portion S and the container 2, that is, the base portion 3 are configured to be coupled. The base portion 3 is sewn in advance to the back surface 2c of the container 2, and as shown in Fig. 2, is fixed with the convex lower inclined surface 6b of the coupling convex portion 6 facing downward, and the left and right convex inclined surfaces 6c and 6d spreading in the left-right direction toward the upper side. Therefore, the base portion 3 is configured as an integral body fixed to the container 2 and is coupled to the clip portion S.

[0051] To connect the base portion 3 (container 2) to the clip portion S, since the clip portion S is already positioned on the strap 12, the user U slides the base portion 3 from top to bottom. That is, the user U positions the base portion 3, i.e., the back surface 2c of the container 2, in front of the user U. Then, the user U lowers the base portion 3 so that it is above the clip portion S.

[0052] As a result, the open side of the connecting recess 19 is wider in the left-right direction than the convex downward inclined surface 6b of the connecting protrusion 6, so the connecting protrusion 6 easily enters the connecting recess 19. Further lowering the base portion 3 causes the convex right inclined surface 6d of the connecting protrusion 6 to slide against the concave left inclined surface 19c of the connecting recess 19, and the convex left inclined surface 6c of the connecting protrusion 6 to slide against the concave right inclined surface 19d of the connecting recess 19, while the convex downward inclined surface 6b of the connecting protrusion 6 comes into contact with the concave downward inclined surface 19b of the connecting recess 19.

[0053] To describe the position of the fitting means 20 at this time, when the coupling of the coupling projection 6 to the coupling recess 19 is described, the convex right-sloping surface 6d of the coupling projection 6 slides onto the concave left-sloping surface 19c of the coupling recess 19, and the convex right-sloping surface 6d has not yet reached the groove 21, the rod-shaped portion 22 is in a normal position in which the fitting piece 23 protrudes from the concave left-sloping surface 19c of the coupling recess 19 due to the elasticity of the spring, and the pressing piece 24 protrudes from a specific opposing side surface 18a.

[0054] On the other hand, when the convex right-sloping surface 6d of the connecting projection 6 slides onto the concave left-sloping surface 19c of the connecting recess 19, and the convex right-sloping surface 6d reaches the groove 21, the outer circumference 23a of the fitting piece 23 of the rod-shaped portion 22 is pressed against the convex right-sloping surface 6d, and the rod-shaped portion 22 is pushed to the left against the elasticity of the spring, resulting in a release position where the pressing piece 24 retracts from the specific opposing side surface 18a.

[0055] Furthermore, when the coupling projection 6 is lowered relative to the coupling recess 19 and the downward inclined surface 6b of the projection abuts against the downward inclined surface 19b of the recess, the fitting piece 23 fits into the groove 21, and due to the elasticity of the spring, the fitting piece 23 protrudes from the left concave inclined surface 19c of the coupling recess 19, while the pressing piece 24 protrudes from the specific opposing side surface 18a, resulting in the normal position. Thus, in the case of the fitting means 20, the coupling (fitting) of the coupling projection 6 to the coupling recess 19 proceeds in the order of normal position, released position, and normal position.

[0056] When user U connects the connecting projection 6 to the connecting recess 19 as described above, the clip portion S is held in place on the strap 12 by the clamping of the clip portion S against the strap 12 due to the elasticity of the spring 25, and the base portion 3, i.e., the container 2, is attached to the predetermined position. At this time, the inclination direction of the concave left inclined surface 19c and the convex right inclined surface 6d coincides, and the inclination direction of the concave right inclined surface 19d and the convex left inclined surface 6c coincides, and they are fitted together in the left-right direction. In the normal position of the fitting means 20, the fitting piece 23 is fitted into the groove portion 21, so the connecting projection 6 does not move in the left-right direction or the up-down direction relative to the connecting recess 19, and the connecting projection 6 is securely held by the fitting of the connecting recess 19.

[0057] Furthermore, the connecting projection 6 and the connecting recess 19 can be fitted together with the added force of gravity acting on the container 2 by the contact between the downward inclined surface 6b of the projection and the downward inclined surface 19b of the recess. Thus, the fitted state of the connecting projection 6 and the connecting recess 19 is reliably maintained.

[0058] In this way, the mobile phone and other items are stored in the container 2. The container 2 is held perpendicular to the clip portion S, so even if the user U rides a bicycle or the like and an external force is applied to the container 2, causing the container 2 to tilt slightly relative to the strap 12, the mobile phone and other items will not fall out of the container 2.

[0059] Furthermore, in the above embodiment, the direction of sliding movement of the connecting projection 6 toward the connecting recess 19 is perpendicular to the direction of the portion that opens and closes when the clip portion S clamps onto the strap 12, that is, the direction connecting the blade portion 28 on one side of the opposing plate portion 8 of the two contact bodies 10 and the pivot shaft 26, which is the opening and closing center of the clip portion S. Therefore, the opening and closing operation of the clip portion S toward the strap 12 does not significantly affect the coupling (fitting) of the connecting projection 6 and the connecting recess 19.

[0060] Now, let's consider the case of removing the container 2 from the clip part S. In this case, we can either remove the clip part S from the strap 12, or remove only the container 2 from the clip part S without removing the clip part S from the strap 12. In any case, the container 2 can be removed from the clip part S in the following way.

[0061] In other words, the user U switches the fitting means 20 from its normal position to its released position. This is done by pressing the pressing piece 24 of the rod-shaped portion 22 against the elasticity of the spring so that it moves to one side of the opposing plate portion 8. Since the rod-shaped portion 22 integrally has the pressing piece 24 and the fitting piece 23, when the pressing piece 24 is pressed, the fitting piece 23 moves. When this happens, the fitting piece 23 comes out of the groove portion 21, and the fitting means 20 is in the released position. In this state, the container 2 can be easily removed from the clip portion S by pulling the connecting projection 6 out of the connecting recess 19.

[0062] Furthermore, the pressing piece 24 is located on the opposite side of the pivot shaft 26 from the part of the clip portion S that is operated for opening and closing when clamping the strap 12 of the backpack 11, that is, on the other side of the opposing plate portion 8. In other words, the pressing piece 24 is located away from the part that is clamped by the clip portion S. Therefore, it is possible to prevent the pressing piece 24 from being accidentally operated when opening and closing the clamping plate portion 7 and the opposing plate portion 8.

[0063] The present invention is not limited to the above embodiment. For example, in the above embodiment, the fitting portion was a rod-shaped portion 22 provided on the opposing plate portion 8 that is movable in the left-right direction. However, the rod-shaped portion body 22A of the rod-shaped portion 22 is not required. In this case, the release operation portion can be formed by directly forming the pressing piece 24 and the fitting piece 23. That is, the pressing piece 24 can be made to protrude from a specific opposing side surface 18a, and the fitting piece 23, which is integrally formed with the pressing piece 24, can protrude from the concave right-sloping surface 19d. The release operation portion can be formed by continuously forming the pressing piece 24 and the fitting piece 23 from an elastic material. In this case, the groove portion 21 is formed on the convex left-sloping surface 6c, rather than on the convex right-sloping surface 6d.

[0064] In the above embodiment, the base portion 3 was formed inseparably from the container 2 by sewing. However, it may also be attached inseparably by means of adhesive, welding, or fastening with metal fittings (rivets), rather than sewing.

[0065] In the above embodiment, the coupling means extending from the base portion 3 to the clip portion S consists of a coupling projection 6 as a first part provided on the base portion 3 and a coupling recess 19 as a second part provided on the clip portion S, and these are designed to change between a coupled state in which they are engaged and a discoupled state in which they are not coupled. In this case, the first and second parts change between the coupled state and the discoupled state in the direction in which the base portion 3 and the clip portion S are slid. However, a combination of grooves and projections can also be considered as the coupling means. For example, a fastener (such as a hook) can be used as the coupling means to make the clip portion S and the base portion 3 detachable in the front-to-back direction. In this way, the container 2 can be easily replaced on the clip portion S.

[0066] In the above embodiment, the first and second parts were slid vertically, but the invention is not limited to this; for example, the base part 3 can be slid horizontally relative to the clip part S. In this case, the direction of the sliding movement is parallel to the direction connecting the part that opens and closes when clamped by the clip part S and the opening and closing center of the clip part S. Another example of the sliding movement is a buckle shape in which the first and second parts engage with each other.

[0067] In the above embodiment, the clip portion S has a coupling recess 19 formed from the upper opposing side surface 18, but the coupling recess 19 may also be formed from the lower opposing side surface 18. In this case, the coupling projection 6 of the base portion 3 is arranged upside down compared to the above embodiment. The concave downward inclined surface 19b and the convex downward inclined surface 6b were curved, but they can also be formed in a straight line. Alternatively, the same shape as the coupling recess 19 may be formed on the base portion 3, and the same shape as the coupling projection 6 may be formed on the clip portion S.

[0068] In the above embodiment, an example was given in which the direction of sliding movement of the connecting projection 6 relative to the connecting recess 19 intersects with the direction connecting the part that opens and closes when clamped by the clip portion S and the opening and closing center of the clip portion S. However, they do not have to intersect. In other words, in the above embodiment, when the clip portion S clamps the strap 12, the recessed downward inclined surface 19b is located on the lower side of the connecting recess 19 and the open side of the connecting recess 19 is located on the upper side, so the connecting recess 19 is in the vertical direction relative to the strap 12. However, the connecting recess 19 can also be formed to be obliquely inclined from the upper opposing side surface 18. In this case, the connecting projection 6 is formed in a shape corresponding to the connecting recess 19. In other words, the container 2 can also be attached to the strap 12 at an angle.

[0069] In the above embodiment, the contact body 10 is formed such that the blade portion 28 engages with the strap 12. However, it is not limited to this, and the contact body may have a configuration that generates a frictional force against the strap 12 to resist falling. For example, it can be made of soft rubber or a material with a napped surface. Furthermore, the blade portion 28 is not limited to a saw-like shape, but can have various shapes such as multiple independent protrusions.

[0070] In the above embodiment, the strap 12 of a backpack 11 was given as the object to which the attachment will be made, but it is not limited to this and can be applied to various items used by the user U, such as the strap of a shoulder bag.

[0071] In the above embodiment, the container attachment / detachment mechanism 1 is configured to include a container 2, a base portion 3, and a clip portion S. However, it is also possible to omit the container 2 and have a configuration that includes only the base portion 3 and the clip portion S, in which case the base portion 3 and the clip portion S together constitute the functional components for the container attachment / detachment mechanism. Furthermore, the base portion 3 and the clip portion S can be manufactured and distributed as separate units.

[0072] In the above embodiment, the clip portion S was given as a component corresponding to the mounting portion. However, the mounting portion is not limited to one that utilizes spring force, and also includes cases where, for example, the container is detachably attached to the object to be mounted by magnetic force in order to hold the position of the object, or where it is detachably attached to the object to be mounted by fitting.
