Description

  [Technical Field] The present invention relates to a bag lid stopper for closing a lid body and locking it to the bag body side in a bag having a lid body capable of closing the opening of the bag body, and more particularly to a bag lid stopper suitable for a school bag.

  Conventionally, as a lid stopper for a heel, a male member disposed on the heel body side, a female member disposed on a distal end side of the lid, and a male member side that is rotatable with respect to the male member There is a configuration that includes an operation knob that is provided and used when the male member and the female member are connected to each other. In this conventional lid lid stopper, a long plate-like slit into which the operation knob rotated by 90 ° is inserted is formed in the substantially flat female member, and the operation in a state where the slit is inserted is formed. By rotating the knob again so as to intersect the slit, the female member was connected to the male member, and the distal end side of the lid body was stopped on the heel body side. In this conventional lid lid stopper, when the female member is brought into contact with the male member and the operation knob is inserted into the slit, the operation knob is disposed in the coil disposed in the male member. The configuration is such that it is automatically rotated so as to be substantially orthogonal to the slit by the restoration of the spring and the rotating plate (see, for example, Patent Document 1).

JP 2011-62338 A

  However, in the conventional lid lid stopper, when the connection state between the male member and the female member is released (when the lid is opened), the operation knob is rotated so as to compress the coil spring. For this reason, children in the lower grades of elementary school need a little stronger power, and there is room for improvement in that they can be operated easily even by small children. In addition, the conventional lid cover stopper has a structure in which the peripheral portion of the slit is pressed by the rotated operation knob itself to connect the male member and the female member, so that the operation knob is inserted into the slit. It was necessary to set the outer shape as possible, it was difficult to change the outer shape of the operation knob, and the design freedom was low.

  The present invention solves the above-described problems, and an object of the present invention is to provide a lid stopper for a bag that can easily open and close the lid and has a high degree of design freedom.

The lid stopper for the bag according to the present invention is a lid stopper for the bag for closing the lid to the bag body side in the bag having a lid that can close the opening of the bag body,
A female member and a male member that are arranged on the distal end side or the lid body side of the lid body and can be engaged with each other, and are arranged on the surface side of the lid body and can be rotated along the surface of the lid body And an operation lever,
The male member or female member arranged on the lid side is configured to be rotatable along the surface of the lid in conjunction with the rotation of the operation lever.
The male member has a protruding portion that protrudes toward the female member side,
The female member is configured to have a recess into which the protrusion can be inserted,
The outer peripheral surface side of the protrusion and the inner peripheral surface side of the recess can be engaged with each other and can be disengaged when one of the male member and the female member is rotated. And at least a pair of engaging protrusions and engaged protrusions are arranged to protrude,
The male member and the female member are each configured to have a magnet,
When the magnet engages the engaging protrusion and the engaged protrusion, a magnetic force that attracts each other acts, and the operation lever rotates in a direction to release the engagement between the engaging protrusion and the engaged protrusion. It is characterized by being disposed on the male member and the female member so that a repulsive magnetic force acts when moving.

  In the lid stopper for scissors according to the present invention, the female member and the male member respectively disposed on the distal end side or the scissor body side of the lid body are each provided with a magnet, and these magnets are engaging projections. When the operating lever is engaged, a magnetic force attracting each other is applied, and when the operation lever is rotated, a repulsive magnetic force is applied. In the lid stopper for the bag according to the present invention, when the operation lever is rotated from the state in which the engaging protrusion and the engaged protrusion are engaged, the female member or the male member disposed on the cover body side is provided. The mold member is rotated in conjunction with the operation lever, so that the engagement state between the engagement protrusion and the engagement protrusion is released, and as described above, the magnets repel each other. Become. For this reason, the female member or male member disposed on the lid side engages with the engaging protrusion and the engaged member with respect to the male member or female member disposed on the heel body side when the operation lever is rotated. At the same time that the engagement with the mating protrusion is released, the repulsive force acting between the magnets is received and the male member or female member on the heel body side is easily separated. Further, when the male member and the female member are engaged with each other, if the protruding portion formed on the male member is inserted into the concave portion formed on the female mold portion, the male member and the female member are disposed on the lid side. The magnets are attracted to the magnets arranged on the main body side, and are rotated together with the female member or the male member arranged on the lid side and the operation lever, so that they are attracted to each other. Using the magnetic force, the male member and the female member are engaged with each other semi-automatically so that the engaging protrusion and the engaged protrusion are engaged. For this reason, the lid stopper for scissors according to the present invention engages or disengages the female member and the male member by supplementarily using the magnetic force of the magnets arranged on the male member and the female member. Since it is the structure to which it is made, engagement and disengagement of a female-type member and a male-type member are easy, and even a small child of an elementary school lower grade can operate easily.

  Moreover, in the lid stopper for the heel of the present invention, the male member or the female member arranged so as to be interlocked with the operation lever is engaged with the female member or the male member arranged on the heel body side. Therefore, the lid is fixed to the bag body, and the male lever and the female mold member are not connected using the operation lever itself. It is possible to greatly change the outer shape. Therefore, it is possible to manufacture a lid stopper for a bag having a high degree of freedom in designing the operation lever and rich in design.

  Therefore, the lid stopper for a bag of the present invention has good operability, can easily open and close the lid body, and has a high degree of freedom in design.

  Moreover, in the lid stopper for scissors according to the present invention, the engaging protrusions are formed at two locations that are substantially symmetrical about the rotation center of the operation lever, and are each approximately ¼ of the circumference of the protrusion. If it is configured to be continuously formed in a certain area, the engagement state can be stably maintained by the two pairs of engagement protrusions and the engagement protrusions arranged at symmetrical positions, In addition, since the engagement state between the engagement protrusion and the engagement protrusion cannot be released unless the operation lever is rotated about 90 °, the operation lever is inadvertently rotated to engage the engagement protrusion and the engagement protrusion. It is possible to prevent the engagement state with the mating protrusion from being released, which is preferable.

Furthermore, in the lid lid stopper of the above-described configuration, the operation lever is only in the right angle region when viewed from the user side with respect to the non-rotating position where the engagement protrusion and the engagement protrusion are engaged . , Rotatable to the right, which is a direction for releasing the engagement between the engaging protrusion and the engaged protrusion, and to the left, which is a direction for engaging the engaging protrusion and the engaged protrusion , and If the rotation angle is set within a range of 120 ° or less, the rotation range of the operation lever is determined. Therefore, if the operation lever is rotated to the right until it stops, the male lever can be reliably connected. Compared with the case where the engagement state between the mold member and the female mold member can be released, the operation lever can be rotated to the left and right, and the rotation range is not defined. Easy to operate.

Furthermore, in the lid stopper for scissors with the above configuration, the male member is disposed on the lid body side,
Each engaging protrusion is formed on the distal end side of the protruding portion, and the outer surface is inclined so as to be expanded toward the base portion side in a section along the rotation center axis of the operation lever.
Place the female member on the heel body side,
Each engaged protrusion is configured so that the inner surface is inclined substantially along the outer surface of each engaging protrusion in the cross section along the rotation center axis of the operation lever, and is inwardly formed by the urging means. It is preferable to adopt a configuration that is attached to the inner peripheral surface side of the recess in a state of being biased so as to protrude toward the front.

  In the lid stopper for a bag having the above-described configuration, in the female member, each of the engaged protrusions arranged so as to protrude from the inner peripheral surface of the concave portion has the inner peripheral surface of the concave portion recessed through the biasing means. It is the structure attached to the storage site | part formed, These engagement protrusions can be pressed against the urging | biasing force of a biasing means, and can be moved so that it may be accommodated in a storage site | part. Further, the inner surface of the engaged protrusion is inclined so as to substantially follow the outer surface of each engaging protrusion formed on the male member. For this reason, in the lid lid stopper with the above configuration, even when the male member is brought close to the female member in a state where the operation lever is in the non-rotating position, each engaged protrusion protrudes into the recess. When the protrusion is pushed by the engaging protrusion, it can be moved so as to be stored in the storage portion, and when the insertion of the protruding portion into the concave portion is completed, each engaged protrusion Then, the urging means is restored to return so as to protrude from the inner peripheral surface of the recess, and is engaged with each engaging protrusion. That is, in the lid stopper for a bag having the above-described configuration, even if the operation lever (male member) is disposed at a non-rotating position, the male member is simply rotated without rotating the operation lever. The engaging protrusion can be engaged with the engaged protrusion simply by inserting the protruding portion into the recess of the female member. At this time, magnetic forces attracting each other are generated between the magnets disposed on the male member and the female member, respectively. Therefore, in the lid stopper for the heel having the above-described configuration, the male member and the operation lever can be moved by bringing the male member disposed on the distal end side of the lid body closer to the female member disposed on the heel body side. Even in such a state, the male member moves semi-automatically so as to insert the protrusion into the recess by the mutual magnetic force generated between the magnets, and engages with the engagement protrusion. The protrusions are engaged with each other semi-automatically. As a result, the operability is further improved if the lid stopper for the bag is configured as described above.

  Further, the lid stopper for the bag having such a configuration can be suitably used for the school bag. When used for the school bag, the female member or the male member arranged on the bottom surface side of the bag body is arranged in the front-rear direction. A configuration in which two are arranged side by side is preferable because the position at which the lid is stopped can be adjusted according to the amount of the stored items in the bag main body.

  Further, in the school bag having the lid stopper for the heel having the above-described configuration, the amount of protrusion from the bottom surface of the heel body of the Dharma seat bracket, which is disposed on both the left and right sides of the lid stopper for the heel, When configured to be larger than the protruding amount of the operating lever from the bottom surface in a state where the male member and the female member are engaged, the bottom surface of the heel body is placed downward in use. The operation lever can be prevented from being damaged, for example, even if a decorative rhinestone having a good design is used for the operation lever, the durability of the operation lever can be improved. The stone can be prevented from coming off.

It arrange | positions so that a strong magnetic force may act. In the case of the embodiment, the magnets 62 have different poles in the front and rear, the rear half region is the S pole 62S, and the front half region is the N pole 62N (see FIG. 18).

  As described above, the Dharma metal fitting 65 for connecting the lower end of the back belt 9 passes through the attachment portions 29 on both the left and right sides of the pedestal portion 13 with the spacer 30 interposed therebetween, and the bottom wall of the storage portion 3. It is attached to 3c using the crimping hook 66 (refer FIGS. 2-6). In the embodiment, the Dharma bracket 65 interposes the spacer 30 between the male member 53 and the female part 19 so that the protruding amount H1 from the bottom surface of the storage part 3 is obtained as shown in FIG. It is comprised so that it may become larger than the protrusion amount H2 from the bottom face of the operation lever 43 in the engaged state.

  Next, attachment / detachment of the lid 5 to the storage unit 3 using the lid stopper 11 of the embodiment will be described. In a state in which the lid 5 is attached to the storage portion 3, that is, in a state in which the operation lever 43 in which the engagement protrusion 55 and the engagement protrusion 22 are engaged with each other is not rotated, it is disposed on the male member 53 side. As shown in FIG. 22A, the magnet 62 and the magnet 27 arranged on the female mold part 19 side are reversed in the front and rear direction and viewed from the up and down direction side between them. These are arranged by applying a magnetic force (attraction magnetic force) that attracts each other over the entire surface. Further, in the lid stopper 11 of the embodiment, as shown in FIGS. 4 and 5, the magnets 27 and 62 are arranged close to the magnet storage portions 16 and 60 covering the periphery so as to provide a slight gap therebetween. Since the magnet storage portions 16 and 60 are only interposed between the magnets 27 and 62, a magnetic force that attracts the magnets 27 and 62 is exerted between the magnets 27 and 62. At this time, the protrusion main body 23 of the engaged protrusion 22 is engaged with the engagement protrusion 55 over the entire area in the circumferential direction, as shown in FIG. In this state, if the operation lever 43 is rotated to the right side, the male member 53 and the magnet 62 are also rotated to the right side in conjunction with the operation lever 43, and this operation is performed between the magnets 62 and 27. As the lever 43 rotates, the surfaces (see shaded portions in FIG. 22) on which magnetic forces (repulsive magnetic forces) that repel each other act gradually increase as shown in FIGS. 22B and 22C. Go. Then, when the rotation angle reaches 90 °, the area of the surface acting on the attractive magnetic force and the surface acting on the repulsive magnetic force between the magnets 62 and 27 become substantially the same (see D in FIG. 22). By the rotation of the engaging protrusion 55 to the right side, the engagement between the engaging protrusion 55 and the protrusion main body 23 of the engaged protrusion 22 is also completely released. If the control lever 43 is further rotated to the right, the area of the surface on which the repulsive magnetic force acts between the magnets 62 and 27 reverses the area of the surface on which the attractive magnetic force acts, as shown in E of FIG. Since the force increases, the repulsive magnetic force generated between the magnets 62 and 27 causes the male member 53 to move semi-automatically so as to lift from the female mold portion 19, and the operation lever 43 and the connecting plate portion 33 together with the pedestal portion. Thus, the lid 5 can be detached from the storage unit 3.

  On the contrary, when the lid 5 is attached to the storage portion 3, the operation lever 43 and the connecting plate portion 33 are brought close to the pedestal portion 13 in a state where the operation lever 43 is rotated, and the protruding portion of the male member 53. If 54 is inserted into the recess 20 of the female mold part 19, as shown in FIG. 23, the protrusion main body 23 of the engaged protrusion is maintained in the protruding state from the inner peripheral surface 20a of the recess 20, It will be inserted into the notch 37 of the cover 36. Then, if the operating lever 43 is rotated to the left side, the magnets 62 arranged on the male member 53 side receive an attractive magnetic force attracting each other and return to the non-rotating state to the left side. The magnet 27 is in contact with the magnet 27 on the female mold portion 19 side through the magnet storage portions 16 and 60 while being rotated. Then, with the rotation of the magnet 62 on the male member 53 side, the operation lever 43 and the male member 53 are also rotated to the left side, and the engagement protrusion 55 disposed on the male member 53 becomes the female die. The lid body 5 can be attached to the storage portion 3 by being engaged with the projection main body 23 of the engaged projection 22 arranged in the portion 19.

  Further, when the lid 5 is attached to the storage portion 3, in a state where the operation lever 43 is returned to the non-rotating position, if the operation lever 43 is brought close to the base portion 13 together with the connecting plate portion 33, the magnet 27 and 62 are attracted to each other, and the protrusion 54 of the male member 53 receives the attractive magnetic force generated between the magnets 27 and 62 and is semi-automatically inserted into the recess 20 of the female die 19. It becomes. At this time, as shown in FIG. 24, the engagement protrusion 55 formed on the male member 53 causes the engagement protrusion 22 formed on the female mold portion 19 to be compressed outwardly as the coil spring 25 is compressed. If the magnets 27 and 62 are brought into contact with each other via the magnet storage portions 16 and 60, the coil spring 25 is restored and engaged. The mating protrusion 22 returns to the steady position, and the engaging protrusion 55 disposed on the male member 53 is engaged with the protrusion main body 23 of the engaged protrusion 22 disposed on the female mold portion 19. Thus, the lid 5 can be attached to the storage portion 3.

  In the lid stopper 11 of the embodiment, the female part 19 (female member) and the male member 53 respectively disposed on the distal end 7a side of the lid body 5 or the storage part 3 (saddle body) side are respectively provided with the magnet 27. 62, and these magnets 27, 62 act to attract each other when the engaging protrusion 55 and the engaged protrusion 22 are engaged, and when the operation lever 43 is rotated. It is a configuration that is arranged so as to apply a repulsive magnetic force. And in the lid stopper 11 for hooks of embodiment, if the operation lever 43 is rotated from the state which the engagement protrusion 55 and the to-be-engaged protrusion 22 are engaged, it will be arrange | positioned at the cover body 5 side. When the male member 53 is rotated in conjunction with the operation lever 43, the engagement state between the engagement protrusion 55 and the engagement protrusion 22 is released, and as described above, the magnet 27, 62 will repel each other. Therefore, when the operation lever 43 is rotated, the male member 53 disposed on the lid 5 side engages with the female protrusion 19 disposed on the storage unit 3 (鞄 body) side. At the same time, the engagement state between the engagement portion 22 and the engaged protrusion 22 is released, and at the same time, the repulsive force acting between the magnets 27 and 62 is received to easily separate from the female portion 19 on the side of the storage portion 3 (鞄 main body). . Further, when the male member 53 and the female mold portion 19 are engaged with each other, if the protruding portion 54 formed on the male mold member 53 is inserted into the concave portion 20 formed on the female mold portion 19, The magnet 62 disposed on the lid 5 side is attracted to the magnet 27 disposed on the storage unit 3 (bag main body) side and rotated together with the male member 53 and the operation lever 43 disposed on the lid 5 side. Thus, the male member 53 and the female mold portion 19 engage the engaging protrusion 55 and the engaged protrusion 22 by utilizing the magnetic force generated between the magnets 27 and 62 to attract each other. As a result, they are engaged with each other semi-automatically. Therefore, the lid stopper 11 of the embodiment uses the magnetic force of the magnets 62 and 27 arranged on the male member 53 and the female die part 19 to assist the female die part 19 and the male member 53. Since it is a structure which engages or disengages, the engagement and disengagement of the female mold part 19 and the male mold member 53 are easy, and even a small child of an elementary school lower grade can operate easily.

  Further, in the lid stopper 11 of the embodiment, the male mold member 53 disposed so as to be interlocked with the operation lever 43 is engaged with the female mold section 19 disposed on the storage section 3 (the bag body) side. The lid 5 is configured to be secured to the storage unit 3 (the main body of the bag), and is not configured to connect the male member 53 and the female mold unit 19 using the operation lever 43 itself. If it is a shape, the outer shape of the operation lever 43 can be greatly changed. Therefore, the design of the operation lever 43 is high and the lid stopper 11 rich in design can be manufactured.

  Therefore, the lid stopper 11 of the embodiment has good operability, can easily open and close the lid 5, and has a high degree of design freedom.

  Further, in the lid stopper 11 of the embodiment, the engagement protrusions 55 are formed at two locations that are substantially symmetrical about the rotation center of the operation lever 43, and approximately 1 of the circumference of the protrusion 54. / 4 is continuously formed in a region of about / 4, so that the engagement state is stably maintained by the two pairs of engagement protrusions 55 and the engagement protrusions 22 arranged at symmetrical positions. be able to. Further, since the engagement state between the engagement protrusion 55 and the engagement protrusion 22 cannot be released unless the operation lever 43 is rotated by about 90 °, the operation lever 43 is inadvertently rotated and engaged. It is also possible to prevent the engagement state between the protrusion 55 and the engaged protrusion 22 from being released. Of course, if this point is not taken into consideration, the engagement protrusion may be configured to shorten the length dimension along the circumferential direction of the protrusion.

  Furthermore, in the lid stopper 11 of the embodiment, the operation lever 43 can be rotated only to the right when viewed from the user side, and the rotation angle is set within a range of 120 ° or less, A rotation range of the operation lever 43 is determined. Therefore, if the operation lever 43 is rotated rightward until it stops, the engagement state between the male member 53 and the female mold portion 19 can be surely released, and the operation lever can be moved to either the left or right. It is easier to operate the operation lever as compared with the case where the rotation is possible and the rotation range is not defined. Of course, if such a point is not taken into consideration, the operation lever may be configured to be rotatable to the left and right and not to define a rotation range.

  Furthermore, in the lid stopper 11 of the embodiment, each engaging projection 55 of the male member 53 disposed on the lid 5 side is formed on the tip 54a side of the protruding portion 54 and the operation lever 43 is rotated. In the cross section along the central axis C1, the outer surface 55a is inclined so as to expand toward the base side. And the protrusion main body 23 in each to-be-engaged protrusion 22 of the female-type part 19 arrange | positioned at the accommodating part 3 (bag main body) side each has the inner surface 23a in the cross section along the rotation center axis | shaft of the operation lever 43. The inner surface of the concave portion 20 is configured so as to be inclined substantially along the outer surface 55a of each engaging projection 55 and urged so as to protrude inward by a coil spring 25 as urging means. It is attached in the storage part 19a formed by denting the peripheral surface 20a. That is, in the lid stopper 11 of the embodiment, the protrusion main body 23 of the engaged protrusion 22 disposed on the female mold portion 19 is pressed against the urging force of the coil spring 25 and stored in the storage portion 19a. Can be moved. Further, the inner surface 23 a of the protrusion main body 23 in the engaged protrusion 22 is configured to be inclined so as to substantially follow the outer surface 55 a of each engaging protrusion 55 formed on the male member 53. Therefore, in the lid stopper 11 of the embodiment, even if the male member 53 is brought close to the female mold portion 19 with the operation lever 43 being in the non-rotating position, the projection main body 23 of each engaged projection 22. Can be moved so as to be housed in the housing portion 19a by being pressed by the engaging protrusion 55 as the projecting portion 54 enters the recessed portion 20, and into the recessed portion 20 of the projecting portion 54. When the insertion is completed, the protrusion main body 23 of each engaged protrusion 22 is restored so as to protrude from the inner peripheral surface 20a of the recess 20 so that the coil spring 25 is restored, Will be engaged.

  That is, in the lid stopper 11 of the embodiment, even if the operation lever 43 (male member 53) is disposed at the non-rotation position, the operation lever 43 is not rotated, but the male lever simply. The engaging protrusion 55 can be engaged with the engaged protrusion 22 simply by inserting the protruding part 54 of the mold member 53 into the recess 20 of the female mold part 19. At this time, a magnetic force attracting each other is generated between the magnets 62 and 27 arranged in the male member 53 and the female mold portion 19, respectively. Therefore, in the lid stopper 11 of the embodiment, if the male mold member 53 disposed on the distal end 7a side of the lid body 5 is brought close to the female mold section 19 disposed on the storage section 3 (bag main body) side, Whatever the state of the male member 53 and the operation lever 43, the male member 53 semi-automatically moves the protrusion 54 into the recess 20 by the mutual magnetic force generated between the magnets 62 and 27. The engaging protrusion 55 and the engaged protrusion 22 are semi-automatically engaged with each other. As a result, the operability during opening and closing is further improved. Of course, if such a point is not taken into consideration, the engaged protrusion does not have to be arranged in the recess of the female mold part via the biasing means.

  Moreover, in the lid stopper 11 of embodiment, since the two female-type parts 19 arrange | positioned at the bottom face (bottom wall 3c) side of the accommodating part 3 (bag main body) are arranged in parallel along the front-back direction. The position at which the lid 5 is stopped can be adjusted according to the amount of the stored item in the storage unit 3, which is suitable for the school bag 1. Of course, if such a point is not taken into consideration, only one female mold portion may be arranged.

  Furthermore, in the school bag 1 of the embodiment, the Dharma seat metal fittings 65 arranged on the left and right sides of the lid stopper 11 and locking the lower end of the shoulder belt 9 are attached to the attachment portion 29 in the pedestal portion 13 with the spacer 30 interposed therebetween.
