Description

Bag lid stopper

[Technical Field] The present invention relates to a bag lid stopper that locks a sag lid by connecting a male part and a female part. In the present specification, a lid stopper in a school bag will be described below as an example.

As is well known, the school bag includes a substantially rectangular bottomed cylindrical bag body, and a lid that covers a part of the upper opening and the outer periphery of the bag body. The bag body is provided with a strap for the user to carry it. In addition, the extending portion extending from the lower portion of the dripping lid is provided on the dripping lid. The extension portion is provided with a female portion constituting a lid stopper. In addition, the bag body is provided with a male portion constituting a lid stopper together with the female portion. In the lid stopper, the dripping lid is locked by connecting the male part and the female part.

Patent Documents 1 to 3 listed below disclose lid stoppers for locking the lid. In any of the lid stoppers of the literature, a male part is provided on the bag body, a female part is provided on an extension from the sagging lid, and the sagging lid is locked by the male-female connection between the male part and the female part. The male part includes an operation knob that protrudes from the bag body and rotates to the left and right. The female part has a substantially rectangular insertion hole through which the operation knob is inserted. In these lid stoppers, after the male operation knob is inserted into the insertion hole of the female section, the operation knob is rotated 90 ° to the left or right to lock the drooping lid.

Usually, the lid stopper is provided with a magnetic body (magnet) to attract the male part and the female part when the male and female are connected. The magnet is mainly provided on the male part side, and the male part and the female part can be attracted by a magnetic force by forming the female part with a magnetic body (magnetic metal) such as iron.

Also, the following Patent Document 4 discloses a coupling module using magnetic force. According to the coupling module disclosed in this document, it is possible to perform the locking mechanically, and simultaneously satisfy the three matters that the two coupling modules are attracted to each other at the time of coupling and the coupled state can be easily released. When such a coupling module is applied to a lid stopper for a bag such as a school bag, one of the two coupling modules is provided on the movable side such as a lid or an extension from the lid, and the other is a bag body. Etc. are provided on the fixed side. One coupling module (for example, this is a movable coupling module) is mainly composed of a magnet (movable magnetic body) and a braking piece having a gap. The braking piece is coupled to the movable-side magnetic body through a coupling mechanism. The other coupling module (for example, this is a fixed-side coupling module) is mainly composed of a ferromagnetic contact piece (fixed-side magnetic body), a lock piece, and a spring lock member. When the movable-side coupling module approaches the stationary-side coupling module, the lock piece comes into contact with the braking piece, and is attracted by the magnetic force between the movable-side and fixed-side magnetic bodies, and the lock piece held by the spring action is braked. The pieces engage. When releasing the coupling state, the spring lock member is displaced to the extent that the lock piece is released because the lock piece faces the gap, and the magnetic force is attenuated by the displacement of the movable side magnetic body, and the fixed side The magnetic body is not attracted to the magnetic body on the movable side, and a soft opening and closing that is comfortable to the touch can be realized.

7 and 8 show an example (specific example) of the above-described coupling module. In the

coupling modules

101 and 102 in the examples of FIGS. 7 and 8, the braking piece 103 is connected with a clearance by a stopper via a magnet (movable magnetic body) 104. When a plurality of sets of magnets 104 are used in the pivotable closing part (coupling module 101), the opening angle for releasing the coupling state is preferably 120 °. When four spring lock members 105 are used for better holding, the opening angle is preferably 60 ° in order to displace the gap 106. In the example of FIGS. 7 and 8, the movement of the brake piece 103 and the magnet 104 is connected with a clearance of about 60 ° via an indirect connection mechanism 107 (a connection notch 107a and a connection engagement piece 107b). As a result, the closing position and the opening position are synchronized. 7 and 8, reference numeral 105a denotes a lock piece of the spring lock member 105, and reference numeral 108 denotes a magnet (fixed side magnetic body) of the fixed side coupling module 102.

However, the above-described conventional bag lid stoppers (Patent Documents 1 to 3) have drawbacks such as a complicated structure, a large number of parts, and a heavy metal part. Further, when connecting the male part and the female part, it is necessary to rotate the operation knob to fix the male and female, and when releasing the connection, the male part and the female part attracted by the magnetic force after the operation knob is rotated. The operation to pull apart was necessary, and the operability was poor. Such poor operability has been particularly difficult for people who are handicapped.

In addition, in the coupling module as shown in FIGS. 7 and 8 (the above-mentioned Patent Document 4), it is necessary to rotate the closing portion (coupling module 101) serving as the operation portion by about 120 ° when releasing the connection. As with the conventional lid stopper described above, there is room for improvement in operability.

Therefore, the present invention has been made in view of such a situation, and an object thereof is to provide a lid stopper for a bag having a simple configuration, a small number of parts, a light weight, and good operability.

Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The lid stopper for a bag according to claim 1 of the present invention comprises a bag body 2 and a male part 11 and a female part 12 which are provided on the sagging lid 3 or an extension 5 from the sagging lid 3, A bag lid stopper 10 for locking the sag lid 3 to the bag body 2 by the male and female connection of the male part 11 and the female part 12,

magnetic bodies

24 and 34 is divided.

According to such a configuration, when the male part 11 and the female part 12 are connected to each other, the male part 11 and the female part 12 are attracted by the magnetic force between the

magnetic bodies

24 and 34, so that the male and female can be easily connected. . Further, the magnetic force attracting the male part 11 and the female part 12 assists the engagement of the male part 11 and the female part 12 when the male and female are connected. Further, when the male and female are connected, the claw portion 32a of the female portion 12 enters the groove portion 22 of the male portion 11, and the male portion 11 and the female portion 12 are mechanically engaged. Therefore, the dripping lid 3 can be firmly locked. . Further, when the slide member 29 is pressed in a predetermined direction when the male and female connections are released, the mechanical engagement between the male part 11 and the female part 12 is released, and the

magnetic bodies

24 and 34 are separated from each other. Since the attractive magnetic force between 34 is divided, the male and female connection can be easily released.

magnetic bodies

24 and 34 provided in the male part 11 and the female part 12.

According to such a configuration, when the male and female couplings are released, the

magnetic bodies

24 and 34 of the male part 11 and the female part 12 are separated so that the centers of the N and S poles are shifted and the direction of the magnetic field is repelled. The convex portion 21 of the male portion 11 is surely detached from the inside of the concave portion 27 of the female portion 12. As a result, the male and female connection can be easily and reliably released.

According to the bag lid stopper according to the present invention, the number of parts is small, the configuration is simple, and the metal parts such as magnetic metal are hardly used, so that the weight is light. Furthermore, since the male / female connection is automatically released when the slide member is slid, the male / female connection can be released by one operation (one touch), for example, even a handicapped person can easily operate. it can. That is, the operability is good.

As shown in FIG. 4, the male portion 11 and the female portion 12 are connected to the groove portion 22 of the convex portion 21 and the slide member when the male portion 11 and the convex portion 21 of the male portion 11 are inserted into the concave portion 27 of the female portion 12. 29 claw portions 32a are engaged and mechanically locked. At this time, the male part 11 and the female part 12 are attracted by the magnetic force between the N-pole magnet 24 of the male part 11 and the S-pole magnet 34 of the female part 12 to assist the engagement.

From here, with reference to FIG.5, 6, the operation | movement of each part at the time of carrying out the male-and-female connection of the male part 11 and the female part 12 and releasing the male-female connection is demonstrated. First, a case where male and female are connected will be described.
As shown in FIG. 5A, in the female part before male-female connection, the slide member 29 is pushed downward inside the casing 26 by the urging force of the coil spring 37, and the claw 27 The part 32a has advanced. Further, in the male part 11 and the female part 12, the convex part 21 is attracted to the inside of the concave part 27 by the magnetic force between the N-pole magnet 24 and the S-pole magnet 34.

As shown in FIG. 5C, when the convex portion 21 of the male portion 11 completely enters the concave portion 27 of the female portion 12, the slide member 29 is pushed downward by the urging force of the coil spring 37, and the convex portion The claw portion 32a engages with the groove portion 22 of the 21 to mechanically lock the convex portion 21. At this time, the engagement between the groove portion 22 and the claw portion 32a is maintained until the male-female connection is released by the biasing force of the coil spring 37, and this engagement is performed by the magnetic force between the N-pole magnet 24 and the S-pole magnet 34. Assist.

Next, a description will be given of when the male-female connection is released.
As shown in FIG. 6A, when a pressing force A is applied with a finger or the like from below in the male and female connection state, the slide member 29 opposes the urging force of the coil spring 37 as shown in FIG. While sliding up. By the sliding movement of the slide member 29, the claw portion 32 a is released from the groove portion 22 of the convex portion 21 to be disengaged, and the inclined surface 31 a of the projecting piece 31 of the slide member 29 that has advanced into the concave portion 27. The tapered peripheral edge of the convex portion 21 is pushed, and the convex portion 21 is forcibly pushed out from the inside of the concave portion 27. At this time, as the slide member 29 slides, the S-pole magnet 34 moves upward and is separated from the N-pole magnet 24, and the magnetic force therebetween is divided. In addition to this, when the centers of the

magnets

24 and 34 are shifted, the direction of the magnetic field changes to a repelling direction, and both the

magnets

24 and 34 repel.

As shown in FIG. 6C, after the convex portion 21 is pushed out from the inside of the concave portion 27, when the pressing force A from below is not applied, the slide member 29 is moved by the biasing force of the coil spring 37 to the housing 26. Is pushed downward to return to the state before the male and female connections.

According to the above-described embodiment, when the male part 11 and the female part 12 are connected to each other, the male part 11 and the female part 12 are attracted by the magnetic force between the N-pole magnet 24 and the S-pole magnet 34. It becomes possible. Further, the magnetic force attracting the male part 11 and the female part 12 assists the engagement of the male part 11 and the female part 12 when the male and female are connected. Further, when the male and female are connected, the claw portion 32a of the female portion 12 enters the groove portion 22 of the male portion 11, and the male portion 11 and the female portion 12 are mechanically engaged. Therefore, the dripping lid 3 can be firmly locked. . Further, when the slide member 29 is pressed from below when the male and female connections are released, the mechanical engagement between the male part 11 and the female part 12 is released, and the S pole magnet 34 is separated from the N pole magnet 24, whereby the N pole magnet. Since the magnetic force between the magnetic pole 24 and the S-pole magnet 34 is divided and the

magnets

24 and 34 are repelled, the male-female connection can be easily released.

Further, as the slide member 29 slides, the projection 21 of the male part 11 is pushed by the projecting piece 31 to forcibly separate from the inside of the concave part 27 of the female part 12, so that reliable male-male disconnection is achieved. It becomes possible.

Furthermore, most of the parts constituting each part excluding the magnetic body (N-pole magnet 24, S-pole magnet 34) and coil spring 37 are made of a non-magnetic body such as a resin, and the weight is reduced.

In the above-described embodiment, the male part 11 and the female part 12 are configured to include the N-pole magnet 24 and the S-pole magnet 34. For example, the

magnetic bodies

24 and 34 of the male part 11 and the female part 12 are provided. If one is a permanent magnet and the other is a magnetic metal such as iron, the cost is lower than when permanent magnets are used for both the male part 11 and the female part 12. In addition, when only one of the magnets is a magnet, the attractive magnetic force is relatively small, so that the male and female connection can be released relatively easily without using the repulsive force between the magnets.
