[0023] [Figure 1] 1 is a perspective view showing a state in which a container attachment / detachment mechanism according to an embodiment of the present invention is used; [Diagram 2] FIG. 13 is a rear view of the container with the base portion sewn onto it. [Diagram 3] FIG. [Figure 4] FIG. [Diagram 5] FIG. [Figure 6]FIG. [Figure 7] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, a container attachment / detachment mechanism according to an embodiment of the present invention will be described. 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 attachment target. 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 attachment target is a strap of a backpack. In the following, in this embodiment, the general up and down directions are defined with the user wearing the backpack.

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

[0026] 1, the case 2 is formed with a bottom, the upper surface of which is an opening 2a, and includes a case front surface 2b, a case rear surface 2c facing the case front surface 2b, both case side surfaces 2d, 2f continuing with the case front surface 2b and the case rear surface 2c, and a case bottom surface 2g continuing with the case front surface 2b, the case rear surface 2c, and both case side surfaces 2d, 2f. A mobile phone can be stored in the case 2 through the opening 2a.

[0027] Next, the base portion 3 will be described. As shown in Fig. 2, the base portion 3 is disposed on the container back surface 2c of the container 2. The base portion 3 includes a sewn portion 4 sewn to the container back surface 2c, a base portion 5 protruding from the sewn portion 4, and a connecting protrusion 6 further protruding from the base portion 5. The base portion 3 is made of a synthetic resin, the sewn portion 4 is made of a flexible synthetic resin, and the base portion 5 and the connecting protrusion 6 are made of a hard synthetic resin.

[0028] The area of ​​the container back surface 2c is formed larger than the area of ​​the sewn part 4. The sewn part 4 is a thin plate-like member shaped like a rectangle that is long in the vertical direction, and the four sides of the rectangle are sewn to the container back surface 2c of the container 2. In other words, the base part 3 is fixed to the container back surface 2c of the container 2 by the sewn part 4 so as to be sewn (sewn 4d) and is inseparable. For this reason, the sewn part 4 of the sewn part 4 is formed of a material and a shape (thickness) that allows a needle to pass through for sewing. In addition, the sewn part 4 is sewn to the container back surface 2c with the center in the left-right direction as the center. The upper end surface 4a of the sewn part 4 is formed parallel to the opening 2a of the container 2, the both side end surfaces 4b of the sewn part 4 are formed parallel to both container side surfaces 2d, 2f of the container 2, and the lower end surface 4c of the sewn part 4 is arranged parallel to the container bottom surface 2g of the container 2.

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

[0030] The joining protrusion 6 is formed to protrude from approximately the center in the left-right and up-down directions of the base 5. The joining protrusion 6 is formed into an approximately rectangular surface with a small area on the side attached to the base 5, and the protruding side is formed into an approximately rectangular surface with an area that gradually increases, and the joining protrusion 6 as a whole is formed into an approximately rectangular parallelepiped shape with a reduced lower left-right direction.

[0031] More specifically, in Figs. 3 and 4, the joining protrusion 6 has a convex upper inclined surface 6a, a convex lower inclined surface 6b, and convex left and right inclined surfaces 6c and 6d protruding from the base 5, and a joining convex surface 6e. In 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 set shorter than the left and right width of the convex upper inclined surface 6a. In other words, the joining protrusion 6 has a shorter left and right width toward the bottom. In addition, the joining convex surface 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. In addition, the upper end side of the joining convex surface 6e is formed parallel to the upper end surface 4a of the sewn part 4, but the lower end side of the joining convex surface 6e is curved so that the center in the left and right direction is convex downward. Therefore, the convex lower inclined surface 6b is inclined toward the base 5 so as to follow the curved state of the joining convex surface 6e. The thickness of the joining protrusion 6 (the surface on which the joining protrusion surface 6e is formed) is set to be greater than the thickness of the base 5.

[0032] Next, the clip portion S will be described with reference to Fig. 1 and Figs. 5 to 7. The clip portion S corresponds to the attachment portion. The clip portion S is formed separately from the base portion 3, and is provided so as to be disposed opposite to the container 2 when the container 2 is attached. In this embodiment, the clip portion S includes a clamping plate portion 7, an opposing plate portion 8, a spring mechanism 9, and an abutting body 10. The clip portion S is held by a strap 12 of a belt-shaped backpack 11, and the clamping plate portion 7 and the opposing plate portion 8 are moved relatively apart against the elasticity of the spring mechanism 9, and then the strap 12 is clamped, held by the abutting body 10, and attached to the strap 12.

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

[0034] The opposing plate portion 8 is disposed so as to face the front side via the strap 12 with the sandwiching plate portion 7 disposed on the back side of the strap 12 of the backpack 11. The opposing plate portion 8 is a curved plate-like member having a predetermined thickness. That is, the opposing plate portion 8 is formed in a plate shape from an opposing rear surface 16 disposed on the base portion 3 side, an opposing front surface 17 attached to the front surface of the strap 12, and an opposing side surface 18 surrounding the opposing rear surface 16 and the opposing front surface 17. Among the opposing side surfaces 18, the opposing side surface 18 on the right side shown in FIG. 6 (hereinafter referred to as the specific opposing side surface 18a) is inclined so as to expand toward the sandwiching front surface 13 side of the sandwiching plate portion 7. Also, as described above, the sandwiching plate portion 7 is formed from a simple plate-like member, whereas the opposing plate portion 8 is formed curvedly at the center of the sandwiching plate portion 7 in the left-right direction as shown in FIG. 5.

[0035] The opposing front surface 17 and the opposing side surface 18 have coupling recesses 19 that can be coupled (fitted) with the coupling protrusions 6. The coupling protrusions 6 and the coupling recesses 19 are coupled relatively detachably in the up-down direction. In this case, the coupling protrusions 6 and the coupling recesses 19 are detachably coupled by sliding movement. Thus, the coupling protrusions 6 and the coupling recesses 19 are coupling means that span the base portion 3 and the clip portion S in the container attachment / detachment mechanism 1, 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 joining recess 19 is a groove having an outer shape corresponding to the joining protrusion 6, and is disposed on the other side of the opposing plate portion 8, i.e., on the side of the specific opposing side surface 18a. The joining recess 19 is located within the opposing front surface 17 and within the upper opposing side surface 18, and has a bottom surface 19a as shown in Figures 5 and 6, and the thickness of the joining recess 19 from the bottom surface 19a is the same as the thickness of the joining protrusion 6e from the surface of the base 5. The joining recess 19 is formed so as to extend from the upper opposing side surface 18 to the lower opposing side surface 18, and has a concave lower inclined surface 19b that faces the convex lower inclined surface 6b in the up-down direction, and concave left-right inclined surfaces 19c, 19d that face the convex left-right inclined surfaces 6c, 6d in the left-right direction. The inclination of the concave lower inclined surface 19b is the same as that of the convex lower inclined surface 6b, and the inclination of the concave left-right inclined surfaces 19c, 19d is the same as that of the convex left-right inclined surfaces 6c, 6d. The vertical height of the joining recess 19 is the same as that of the joining protrusion 6. In this way, the joining recess 19 has an end that is a dead end due to the concave lower inclined surface 19b, and the end opposite to the concave lower inclined surface 19b is open.

[0037] The base portion 3 and the clip portion S are provided with a fitting means 20 for ensuring the fitting of the joining protrusion 6 with the joining recess 19. The fitting means 20 has a fitted portion provided on the joining protrusion 6 and a fitting portion provided in the joining recess 19.

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

[0039] The fitting portion will be described. As a premise, the rod-shaped portion 22 provided on the clip portion S will be described. The rod-shaped portion 22 is disposed on the opposing plate portion 8 of the clip portion S, and the rod-shaped portion 22 has a rod-shaped portion main body 22A that can move in the left-right direction. The rod-shaped portion main body 22A is formed by cutting out the bottom surface 19a of the joining recess 19 in the vertical direction and by cutting out the other side inside of the opposing plate portion 8 adjacent to the joining recess 19 in the vertical direction. The fitting portion is a fitting piece 23 that is integrally formed on one side of the rod-shaped portion main 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 so as to fit the joining protrusion 6 provided on the base portion 3 and the joining recess 19 provided on the clip portion S. Further, the rod-shaped portion 22 has a pressing piece 24 formed integrally on the other side of the rod-shaped portion main body 22A. The pressing piece 24 is operated when releasing the engagement.

[0040] The fitting piece 23 is formed so as to be able to fit into the groove portion 21. The pressing piece 24 can move the rod-shaped portion main body 22A in the left-right direction and can protrude from the specific opposing side surface 18a. The rod-shaped portion 22 is pressed to the other side by the elasticity of a spring (not shown) arranged on one side of the opposing plate portion 8, and the fitting piece 23 has an outer periphery 23a protruding from the concave left inclined surface 19c of the joining recess 19 due to the elasticity of the spring. The pressing piece 24 also protrudes from the specific opposing side surface 18a due to the elasticity of the spring. The rod-shaped portion 22 is slidable relative to the opposing plate portion 8 between a normal position in which the fitting piece 23 protrudes from the concave left inclined surface 19c of the joining 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 support shaft 26 from the portion of the clip portion S where the strap 12 of the backpack 11 is clamped and opened / closed, i.e., on the other side of the opposing plate portion 8.

[0041] In other words, the normal posture and the release posture are a state in which the joining protrusion 6 is not fitted in the joining recess 19, or a state in which the joining protrusion 6 is fitted in the joining recess 19 and the fitting piece 23 is fitted in the groove 21. The release posture is a state in which the joining protrusion 6 is fitted in the joining recess 19 and the fitting piece 23 is fitted in the groove 21, and the fitting piece 23 is separated from the groove 21 as the pressing piece 24 is pushed into the opposing plate 8 (specific opposing side surface 18a). Therefore, since the pressing piece 24 has a function of performing a release operation to operate from the normal posture to the release posture, it can also be called a release operation part, and the pressing piece 24 releases the fitting state of the joining protrusion 6 and the joining recess 19. The pressing piece 24 is located forward of the part where the operation for opening and closing is performed when the clip part S is clamped.

[0042] The spring mechanism 9 will now be described. The spring mechanism 9 uses spring force to bring the clamping front surface 13 and the opposing rear surface 16 on the other sides of the clamping plate portion 7 and the opposing plate portion 8 closer to each other, and the container 2 is held in position relative to the strap 12 of the backpack 11 via the base portion 3 by the clamping between the clamping plate portion 7 and the opposing plate portion 8 to which the spring force is applied.

[0043] As shown in FIG. 5, the spring mechanism 9 is composed of support parts 9A, 9B held in position on the sandwiching front surface 13 and the opposing rear surface 16 of one side of the sandwiching plate part 7 and the opposing plate part 8, and a spring 25 arranged between the support parts 9A, 9B. The support parts 9A, 9B are formed in a pair with a gap in the height direction and are formed into a substantially triangular shape. A support shaft 26 is arranged in the vertical direction at the apex side of the substantially triangle. A kick spring is used as the spring 25, and the support shaft 26 penetrates the winding part of the spring 25, and the spring ends 25a, 25b are abutted against the sandwiching front surface 13 and the opposing rear surface 16 of one side of the sandwiching plate part 7 and the opposing plate part 8.

[0044] The abutment body 10 will now be described. The abutment body 10 is disposed as an anti-slip measure on the inner surface of the portion of the clamping plate portion 7 and the opposing plate portion 8 that opens and closes when the strap 12 is clamped in the clip portion S. The abutment body 10 is formed of an abutment body main body 27 and a blade portion 28. The abutment body main body 27 is disposed on the clamping front surface 13 and the opposing rear surface 16 sides of the other sides of the clamping plate portion 7 and the opposing plate portion 8, and is formed to extend in the left-right direction and in the height direction of the clamping plate portion 7 and the opposing plate portion 8. The blade portion 28 is formed on the inner surface of the abutment body main body 27 and is formed in a saw-like shape in a plan view, and the blade portion 28 is formed continuously in 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, a part of the blade portion 28 on the other side is formed to mesh with each other by the spring force of the spring 25.

[0045] The container attachment / detachment mechanism 1 configured as described above includes a base portion 3 and a clip portion S, and is used so that the base portion 3 and the clip portion S are coupled (fitted) relative to each other in the vertical direction. In this case, as an example, a form will be described in which a user U who uses the container attachment / detachment mechanism 1 of this embodiment attaches the clip portion S to the left strap 12 of a backpack 11, and the base portion 3 is coupled to the clip portion S from above.

[0046] Normally (when not attached to strap 12), clip portion S is in a state in which clamping plate portion 7 and opposing plate portion 8 are closed around pivot 26 by the elasticity of spring 25 of spring mechanism 9, and is formed so that part of blade portion 28 of abutment body 10 engages with them. To attach clip portion S to strap 12 from this normal state, the fingers of user U (right hand fingers) bring one side of clamping plate portion 7 and opposing plate portion 8 closer together against the elasticity of spring 25, separating blade portions 28 of abutment body 10 from each other.

[0047] In this state, in the clip part S, the clamping front surface 13 of the clamping plate part 7 is attached to the back surface of the strap 12, and the opposing rear surface 16 of the opposing plate part 8 is attached to the front surface of the strap 12, and the user U releases his / her fingers from the clip part S. At this time, it is desirable to attach the clip part S horizontally to the strap 12. The parts that open and close when the clip part S is clamped are the blade parts 28 on one side of the clamping plate part 7 and the opposing plate part 8, among the blade parts 28 of both contact bodies 10. By releasing the fingers from the clamping plate part 7 and the opposing plate part 8, both blade parts 28 bite into the surface of the strap 12, and the clip part S is held by the strap 12.

[0048] In this state, the concave lower inclined surface 19b of the joining recess 19 is located on the lower side, and the open side of the joining recess 19 is located on the upper side, so that the joining recess 19 is in the vertical direction with respect to the strap 12. Then, when the user U releases his / her finger, the strap 12 returns to a state close to the normal state. At this time, in the clip portion S, 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 on the opposing plate portion 8 abuts against the front surface of the strap 12, due to the elasticity of the spring 25. Then, the clip portion S is clamped against the strap 12 by the elasticity of the spring 25, so that the clip portion S is held in position and attached to the strap 12. Also, the vertical position of the clip portion S with respect to the strap 12 depends on the preference of the user U. However, the vertical position of the clip portion S is also determined by the balance with the container 2, which will be described later.

[0049] Furthermore, the convex lower inclined surface 6b of the joining protrusion 6 is inclined toward the base 5 so as to follow the curved state of the joining protrusion 6e. This makes it easy to attach the joining protrusion 6 to the joining recess 19 of the clip part S, and since it is curved, it is less likely to get caught compared to a shape with an angle.

[0050] The clip part S and the container 2, i.e., the base part 3, are configured to be joined together, and the base part 3 is sewn to the back surface 2c of the container 2 in advance, and is fixed with the convex lower inclined surface 6b of the joining protrusion 6 facing downward and the convex left and right inclined surfaces 6c, 6d expanding in the left and right direction toward the upper part, as shown in Fig. 2. Thus, the base part 3 is joined to the clip part S in a configuration fixed to the container 2 as an integrated part.

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

[0052] In this way, since the open side of the coupling recess 19 is wider in the left-right direction than the convex lower inclined surface 6b of the coupling protrusion 6, the coupling protrusion 6 can easily enter the coupling recess 19. When the base portion 3 is further lowered, the convex right inclined surface 6d of the coupling protrusion 6 slides against the concave left inclined surface 19c of the coupling recess 19, and the convex left inclined surface 6c of the coupling protrusion 6 slides against the concave right inclined surface 19d of the coupling recess 19 and moves, and the convex lower inclined surface 6b of the coupling protrusion 6 comes into contact with the concave lower inclined surface 19b of the coupling recess 19.

[0053] At this time, to explain the connection of the connecting protrusion 6 to the connecting recess 19 as the posture of the fitting means 20, when the convex right inclined surface 6d of the connecting protrusion 6 slides onto the concave left inclined surface 19c of the connecting recess 19 and the convex right inclined surface 6d has not reached the groove portion 21, the rod-shaped portion 22 is in its normal posture in which, due to the elasticity of the spring, the fitting piece 23 protrudes from the concave left inclined surface 19c of the connecting recess 19 and the pressure piece 24 protrudes from the specific opposing side surface 18a.

[0054] On the other hand, when the convex right inclined surface 6d of the connecting protrusion 6 slides onto the concave left inclined surface 19c of the connecting recess 19 and the convex right inclined surface 6d reaches the groove portion 21, the outer circumferential portion 23a of the fitting piece 23 of the rod-shaped portion 22 is pressed by the convex right inclined surface 6d, and the rod-shaped portion 22 is pressed to the left against the elasticity of the spring, so that the pressing piece 24 assumes a release position in which it retreats from the specific opposing side surface 18a.

[0055] Furthermore, when the coupling protrusion 6 is lowered relative to the coupling recess 19 and the convex lower inclined surface 6b is brought into contact with the concave lower inclined surface 19b, the fitting piece 23 fits into the groove 21, and due to the elasticity of the spring, the fitting piece 23 protrudes from the concave left inclined surface 19c of the coupling recess 19, and the pressing piece 24 protrudes from the specific opposing side surface 18a, assuming a normal position. Thus, in the case of the fitting means 20, the coupling (fitting) of the coupling protrusion 6 to the coupling recess 19 takes place in the order of the normal position, the released position, and then the normal position.

[0056] When the user U couples the coupling protrusion 6 to the coupling recess 19 as described above, the clip portion S is clamped by the strap 12 to which the elasticity of the spring 25 is applied, and the base portion 3, i.e., the container 2, is attached to a predetermined position with the clip portion S held in position by the strap 12. At this time, the concave left inclined surface 19c and the convex right inclined surface 6d have the same inclination direction, and the concave right inclined surface 19d and the convex left inclined surface 6c have the same inclination direction, and are fitted together in the left-right direction, and in the normal position of the fitting means 20, the fitting piece 23 is fitted into the groove portion 21, so that the coupling protrusion 6 does not move left-right or up-down relative to the coupling recess 19, and the coupling protrusion 6 is securely held by the fitting of the coupling recess 19.

[0057] Furthermore, the convex lower inclined surface 6b and the concave lower inclined surface 19b come into contact with each other, so that the engagement between the coupling protrusion 6 and the coupling recess 19 is achieved by applying gravity to the container 2. Therefore, the engagement between the coupling protrusion 6 and the coupling recess 19 is reliably maintained.

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

[0059] In the above embodiment, the direction of the sliding movement of the joining protrusion 6 relative to the joining recess 19 is perpendicular to the direction of the portion that opens and closes when the clip part S is clamped against the strap 12, i.e., the direction connecting the blade part 28 on one side of the opposing plate part 8, among the blade parts 28 of both contact bodies 10, and the support shaft 26 that is the center of opening and closing of the clip part S. Therefore, the joining (fitting) of the joining protrusion 6 and the joining recess 19 is not easily affected by the opening and closing operation of the clip part S relative to the strap 12.

[0060] Now, consider the case where the container 2 is removed from the clip part S. In this case, it is possible to remove the clip part S from the strap 12, or to remove only the container 2 from the clip part S without removing the clip part S from the strap 12. In either case, the container 2 is removed from the clip part S as follows.

[0061] That is, the user U switches the fitting means 20 from the normal position to the release position. To do this, the user presses the pressing piece 24 of the rod-shaped portion 22 so that it moves to one side of the opposing plate portion 8 against the elasticity of the spring. Since the rod-shaped portion 22 has the pressing piece 24 and the fitting piece 23 integrally therewith, 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 goes into the release position. In this state, by pulling the connecting protrusion 6 out of the connecting recess 19, the container 2 can be easily removed from the clip portion S.

[0062] The pressing piece 24 is located on the opposite side of the support shaft 26 from the portion where the strap 12 of the rucksack 11 is clamped by the clip portion S and the operation for opening and closing is performed, i.e., on the other side of the opposing plate portion 8. In other words, the pressing piece 24 is located away from the portion where the clip is clamped by the clip portion S. This makes it possible to prevent the pressing piece 24 from being operated erroneously when the clamping plate portion 7 and the opposing plate portion 8 are opened or closed.

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

[0064] In the above embodiment, the base portion 3 is formed to be inseparable from the container 2 by sewing. However, the base portion 3 may be attached inseparably to the container 2 by adhesion, welding, or metal fittings (rivets) instead of sewing.

[0065] In the above embodiment, the connecting means between the base part 3 and the clip part S is the connecting protrusion 6 as the first part provided on the base part 3 and the connecting recess 19 as the second part provided on the clip part S, and these are changed between a connected state in which they are engaged with each other and a disconnected state in which they are not connected. In this case, the first part and the second part are changed between a connected state and a disconnected state in the direction in which the base part 3 and the clip part S are slid. However, the connecting means may be a combination of a groove and a protrusion. For example, the clip part S and the base part 3 may be detachably attached in the front-rear direction using a clasp (such as a hook) as the connecting means. In this way, the container 2 can be easily replaced with respect to the clip part S.

[0066] In the above embodiment, the first and second parts are slid in the up-down direction, but the present invention is not limited to this. For example, the base part 3 can be slid in the left-right direction 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 center of opening and closing of the clip part S. Another example of the sliding movement may be a buckle shape in which the first and second parts engage with each other.

[0067] In the above embodiment, the clip portion S has the coupling recess 19 formed on the upper opposing side surface 18, but the coupling recess 19 may be formed on the lower opposing side surface 18. In this case, the coupling protrusion 6 of the base portion 3 is arranged upside down compared to the above embodiment. Note that the concave lower inclined surface 19b and the convex lower inclined surface 6b are curved, but they can also be formed linearly. Also, the same shape as the coupling recess 19 may be formed on the base portion 3, and the same shape as the coupling protrusion 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 joining protrusion 6 relative to the joining recess 19 intersects with the direction connecting the part that opens and closes when clamped by the clip part S and the center of opening and closing of the clip part S. However, it does not have to intersect. That is, in the above embodiment, when the clip part S is clamped by the strap 12, the concave lower inclined surface 19b of the joining recess 19 is located on the lower side, and the open side of the joining recess 19 is located on the upper side, so that the joining recess 19 is in the vertical direction relative to the strap 12, but the joining recess 19 can also be formed so as to be inclined obliquely from the upper opposing side surface 18. In this case, the joining protrusion 6 is formed in a shape corresponding to the joining recess 19. That is, the container 2 can also be attached obliquely to the strap 12.

[0069] In the above embodiment, the abutting body 10 is formed so that the blade portion 28 meshes with the strap 12. However, the abutting body is not limited to this, and may have a configuration that generates a frictional force against the strap 12 to resist dropping. For example, application is possible even if the abutting body is made of soft rubber or a member with a brushed surface. In addition, the blade portion 28 is not limited to a saw-like shape, and may have various shapes such as multiple independent protrusions.

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

[0071] In the above embodiment, the container attachment / detachment mechanism 1 is configured to include the container 2, the base portion 3, and the clip portion S. However, it may also be configured to include only the base portion 3 and the clip portion S without including the container 2, in which case the base portion 3 and the clip portion S constitute the functional member for the container attachment / detachment mechanism. Also, it is possible to manufacture and distribute the base portion 3 and the clip portion S as a unit.

[0072] In the above embodiment, the clip portion S is given as an example of a member equivalent to the attachment portion. However, the attachment portion is not limited to one that utilizes a spring force, and may also include, for example, a case in which the container is detachably attached to the attachment object by magnetic force in order to hold the container in position relative to the attachment object, or a case in which the container is detachably attached to the attachment object by fitting.
