Description

[Technical Field]

[0001] To provide a pencil case that is mainly used by children and can be opened, closed, and unlocked with one hand. [Background technology]

[0002] Pencil cases have existed for some time and have been used primarily by children. As described in Patent Document 1, such pencil cases consist of a storage case with an opening, a lid that covers the opening, and magnetic members attached to the storage case and the lid. In conventional general pencil cases, the user would twist the magnetic member with their thumb to release the magnetism, then open the lid and use the writing implements inside the storage case.

[0003] There was a demand for such pencil cases that allowed the lid to be opened without requiring a great deal of force to release the magnetic state, and the invention described in Patent Document 1 discloses that the magnetic member attached to the storage case can be tilted using a hinge to release the magnetic state. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-155024

[0005] However, there was a problem that the tilt of the hinge made it difficult for children to open the pencil case even when the magnetism was released. Furthermore, the hinge could tilt due to an unexpected movement or the impact of dropping the pencil case, causing the lid to open. Furthermore, while conventional pencil cases like this can have their lids open accidentally without a locking component, the presence of a locking component requires the user to perform two steps: unlocking the lock and opening the lid. Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, the present invention aims to provide a pencil case that allows a user to stably and easily open the lid with one hand, and further aims to provide a pencil case that has a locking mechanism that prevents the lid from opening unexpectedly due to the impact of being dropped, etc., and that allows the lock to be released and the lid to be opened in a single action. [Means for solving the problem]

[0007] In order to solve the above problems, the pencil case according to the present invention has a case body and a lid body that covers the case body, and the lid body has a magnetically attached portion that is magnetically attached to a magnet placed on the case body, The lock plate having the magnetically attached portion is slidably disposed on the cover.

[0008] The cover also has a plate holder for accommodating a lock plate having a magnetically attached portion, The plate accommodating body preferably has a plate accommodating space that accommodates the lock plate slidably from the front side to the rear side, and one or more guide portions that guide the sliding of the lock plate.

[0009] The plate housing has a magnetic covering portion that covers a part of the magnetic portion at the rear sliding position of the lock plate, The magnetically attached covering portion preferably has a covering opening portion that opens the front side of the magnetically attached portion at the rear sliding position.

[0010] The lock plate has a plate body with a magnetically attached portion and a lock piece extending from the plate body, It is preferable that the case body is provided with a lock piece engaging portion with which the lock piece engages when the lid is closed.

[0011] The locking piece has a base portion that extends downward from the plate body and has a sloped back surface, and an extended locking portion that extends further forward from a lower front edge of the base portion, The lock piece engaging portion of the case body preferably has a lock piece guide hole having a rear wall, and a lock piece engaging hole that communicates with the lock piece guide hole and faces from the front side to the rear side of the case body. [Effects of the Invention]

[0012] The invention described in claim 1 makes it possible to provide a pencil case that allows the user to open the lid with one hand. That is, the magnetic lock can be released simply by sliding the lock plate, which has a magnetic part that magnetically attaches to the magnet on the case body, and the user can open the lid with one hand.

[0013] According to the invention described in claim 2, the lock plate is accommodated by arranging a plate accommodating body that accommodates the lock plate, and by providing a sliding guide, the lid body can be opened with one hand with stable sliding.

[0014] According to the invention described in claim 3, by partially covering the magnetic part on the plate container and leaving the front side open, the magnetic force with the magnet is reduced when the magnetic part is in the rear sliding position, making it easier to open, and when the lid is closed, the magnetic part at the open part on the front side exerts an action of trying to be magnetically attracted to the magnet, making it easy to lock by magnetic attraction.

[0015] According to the invention of claim 4, a locking piece is arranged on the lock plate, and when the lid is closed, the locking piece engages with the locking piece engagement hole in the case body, thereby providing an even stronger lock. This allows for one-handed opening, and the presence of a second locking mechanism for the locking piece in addition to the first locking mechanism by magnetic attachment provides a stronger locking mechanism.

[0016] According to the invention of claim 5, the back surface of the base of the locking piece is an inclined surface, which allows for easy opening and closing. When the locking plate slides toward the back side, the inclined surface on the back of the locking piece abuts against the back wall of the locking piece engagement portion. Therefore, unless the locking plate is pressed firmly, it cannot overcome the back wall and open the lid. However, by sliding the locking plate further from the abutting position between the inclined surface and the back wall, the lid is pushed up along the inclined surface, which releases the magnetic connection between the magnet and the magnetically attached portion, allowing the lid to be opened smoothly.

[0018] An embodiment of the present invention will be described with reference to the drawings. In this description, the "front side" refers to the left front side in FIG. 1, where the magnet 6 and operating unit 41 of the pencil case 1 are located, and the "rear side" refers to the right rear side in FIG. 1, where the back panel of the pencil case 1 is located. Based on this front side, the right front side in FIG. 1 will be described as the "right" and the left rear side as the "left." Furthermore, "sliding" refers to the planar movement of the lock plate 5, and in this embodiment, refers to planar movement between the front side and the rear side. Regarding the position of the slid lock plate, the position on the front side will be described as the "front sliding position," and the position on the rear side will be described as the "rear sliding position."

[0019] 1 and 2, the pencil case 1 according to this embodiment comprises a lid 3 that covers a case body 2, and has a lock plate 5 that is slidable inside a plate housing 4 attached to the lid 3. The lock plate 5 is slidable from the front side to the back side inside the plate housing 4, and has a magnetically attached portion 7 that is magnetically attached to a magnet 6 (see FIG. 2) installed on the case body 2 in the front sliding position, thereby locking by magnetic attachment, and when it is in the rear sliding position, the magnetic attachment between the magnet 6 and the magnetically attached portion 7 is released, allowing the lid 3 to be opened.

[0020] The case body 2 of this embodiment will be described with reference to Figures 3 and 4. The case body 2 is made of synthetic resin and has a rectangular shape in a plan view, with the top and bottom surfaces recessed inward to form storage spaces S1 for writing implements and the like. The pencil case 1 of this embodiment has storage spaces on the top and bottom surfaces of the case body 2, and the lid 3 opens on both sides, but it may also have other shapes, such as a storage space S formed only on the top surface and a lid 3 that opens on one side.

[0021] The upper and lower planes of the case body 2 are covered by the lid body 3 described below to form the pencil case 1, and a plurality of case connecting parts 11, 11 are arranged on the back panel 10 on the rear side. The lid body 3 is connected to the case connecting parts 11, 11 by connecting the lid body connecting parts 21, 21 of the lid body 3 (see Figure 5).

[0022] Front plate 12, which forms the outer wall on the front side of case body 2, has protruding edges 12a, 12a that protrude outward at the upper and lower edges, and these protruding edges 12a are continuous from front plate 12 to the side plates. Front plate 12 has magnet placement section 13, which is recessed from the periphery and positions magnet 6 in the center in the left-right direction when viewed from above, and has lock piece engaging sections 14, 14 on both the left and right sides of magnet placement section 13. By positioning magnet 6 in this position at magnet placement section 13, it is possible for magnet 6 to be magnetically attracted to magnetically attracted section 7 when lock plate 5, described below, is in the front sliding position.

[0023] The magnet arrangement portion 13 is a recess on both the upper and lower planes, and the lock piece engagement portions 14, 14 have at least a rear wall 14a and a lock piece guide hole 14b that penetrates from the upper plane surrounded by walls to the lower plane. When viewed from the front, at least on the top and bottom, there are lock piece engagement holes 14d, 14d that have locking walls 14c, 14c on the top and bottom and communicate with the lock piece guide hole 14b.

[0024] In this embodiment, the rear edge of the magnet arrangement portion 13 in a plan view is located rearward of the rear edge of the lock piece engagement portion 14, but the two edges may be aligned. As will be described later, the magnetic state is released when the lock plate 5 moves rearward. However, since the rear edge of the lock piece engagement portion 14 is located closer to the front than the rear edge of the magnet arrangement portion 13, the magnetic state is released and the lock piece 50 (see FIG. 8) comes into contact with the rear wall 14a of the lock piece engagement portion 14, allowing the lid 3 to be opened.

[0025] The lid 3 of this embodiment will be described with reference to Figure 5. The lid 3 is formed by welding a backing, cushioning material, a resin skin material, and a resin lining material, and is formed into a single sheet with an upper flat lid portion 20a, a lower flat lid portion 20b, and a back plate portion 20c therebetween. The case body 2 and the lid 3 are connected by connecting the lid connecting portions 21 appropriately arranged on the back plate portion 20c to the case connecting portions 11, 11 of the case body 2 (see Figure 3) as described above.

[0026] The upper flat lid portion 20a and the lower flat lid portion 20b of the lid body 3 have openings 22, 22 that open the central front portion of the case body 2 in a convex shape when connected to the case body 2, giving the upper flat lid portion 20a and the lower flat lid portion 20b a concave shape overall. In the lid body of a normal pencil case, the openings 22, 22 are the positions where the magnetic attachment portion for magnetically attaching to the magnet of the case body is located. The plate container 4 and lock plate 5, which will be described later, are placed in these openings 22, 22 (see Figures 1 and 2).

[0027] Next, the plate holder 4 of this embodiment will be described with reference to Figures 6 and 7. The plate holder 4 is composed of an upper wall 30a having a space 31 in the center of the front side so that it has an inverted U shape in a plan view, and a lower wall 30b having substantially the same outer shape as the upper wall 30a, and is connected by front walls 30c, 30c on both the left and right sides in a front view. Therefore, a plate holder space S2 for accommodating the lock plate 5 is formed between the upper wall 30a and the lower wall 30b.

[0028] The plate holder 4 is placed in the open portion 22 of the lid 3, and is inserted so that the upper wall 30a and the lower wall 30b sandwich the open edge of the open portion 22 of the lid 3. On both sides of the protruding open portion of the generally convex open portion 22, there are portions where the upper wall 30a and the lower wall 30b sandwich the lid 3 over a relatively wide area, and with the plate holder 4 sandwiching the lid 3 in these portions, rivets X, X are driven into two locations to secure the plate holder 4 in place. Note that the plate holder 4 in this embodiment is made of a transparent resin so that the locked and unlocked states can be visually confirmed, but other materials or colored members may also be used.

[0029] The plate container 4 has hanging walls 32, 32 that hang down from the front walls 30c, 30c on both sides below the bottom wall 30b. When the lid 3 is closed with the plate container 4 fixed to the lid 3 by the hanging walls 32, 32, the hanging walls 32, 32 reach a position along the front plate 12 of the case body 2, preventing the front edge of the lid 3 from misaligning with the front plate 12.

[0030] Furthermore, in this embodiment, the plate accommodating body 4 has multiple guide portions arranged inside the plate accommodating space S2 that guide the sliding of the lock plate. In this embodiment, it is provided with a magnetic portion sliding guide 33, a magnetic portion restricting guide 34, a lock plate moving guide 35, a side guide 36, and a lock piece restricting guide 37. All of these guides are guide portions that guide the sliding of the lock plate 5, and although five guides are provided in this embodiment, they may be any one or any other number, and the guide form of the guide portions is not limited.

[0031] First, as a first guide portion, a magnetically attached portion sliding guide 33 is formed in the shape of a thick groove on the top wall 30a of the plate container 4, which is recessed in the center in the left-right direction and extends from the front edge of the space 31 to the rear side. The magnetically attached portion 7 is formed by a rivet as described later, and is formed to rise slightly from the plate main body 40, so that the magnetically attached portion sliding guide 33 guides the magnetically attached portion 7, described later, from the front side to the rear side so as not to be misaligned left and right.

[0032] As a second guide portion, a magnetic portion restricting guide 34 in the form of a protrusion is formed at the rear end of the magnetic portion sliding guide 33, extending in a direction perpendicular to the longitudinal direction of the magnetic portion sliding guide 33. Specifically, while the magnetic portion sliding guide 33 is oriented in the longitudinal direction from the front side to the rear side, the magnetic portion restricting guide 34 extends in the left-right direction, which is a direction perpendicular to the longitudinal direction, and is disposed so that its central portion is positioned along the rear end of the magnetic portion sliding guide 33. While the magnetic portion sliding guide 33 is shaped like a recess, the magnetic portion restricting guide is shaped like a wall.

[0033] The magnetically attached portion restricting guide 34 restricts the sliding magnetically attached portion 7 so that it does not go too far toward the rear side from the rear sliding position. Furthermore, since the magnetically attached portion restricting guide 34 is formed as a wall surface that spans the upper wall 30a and the lower wall 30b, it can be positioned along the open edge of the open portion 22 of the lid body 3 when attached to the lid body 3, thereby enabling the positioning of the lid body 3 and the plate container 4.

[0034] Next, the third guide portion will be described, namely, the lock plate movement guide 35. The lock plate movement guide 35 is formed in the same longitudinal direction on both sides of the magnetic portion sliding guide 33 of the magnetic portion restricting guide 34 that extends in the left-right direction. The lock plate movement guide 35 is a ridge formed to protrude from the bottom wall 30b, and engages with a guide groove 42 (see FIG. 8) formed below the lock plate 5 to guide its movement.

[0035] Furthermore, side guides 36, 36 are formed on both sides of the plate holder 4 as fourth guide portions. The side guides 36, 36 consist of a base end portion 36a extending inward from the left and right front walls 30c, a stepped portion 36b formed so as to be recessed one step to the side from the base end portion 36a, and an extension portion 36c extending further from the stepped portion toward the rear side. The side guides 36, 36 are abutted by side protruding pieces 43, 43 (see Figure 8) that protrude further laterally from the sides of the lock plate 5, and the stepped portion 36b prevents the lock plate 5 from falling off even when it moves toward the front side.

[0036] Furthermore, as a fifth guide portion, concave lock piece restricting guides 37, 37 that restrict the lock pieces 50, 50 when the lock plate 5 is in the rear sliding position are formed on the bottom wall 30b of the plate container 4. When the lock plate 5 reaches the rear sliding position, the lock piece restricting guide 37 restricts the lock plate 5 from moving further rearward.

[0037] Additionally, the bottom wall 30b of the plate housing body 4 has a magnetic covering portion 38 that partially covers the magnetic portion 7 of the lock plate 5 in the rear sliding position. This is the portion where the magnetic portion 7 is in the rear sliding position, and is the same semicircular portion as the magnetic portion sliding guide 33 described above, but with an inverted crescent shape, with a covering open portion 38a that is open on the front side. By providing the magnetic covering portion 38 with this shape, when the magnetic portion 7 is in the rear sliding position, the rear side of the magnetic portion 7 is covered, and the covering open portion 38a on the front side is open.

[0038] By providing such a magnetically attached covering portion 38, when the magnetically attached portion 7 is in the rear sliding position, it is partially covered by the magnetically attached covering portion 38, weakening the magnetic force from the magnet 6 and making it possible to easily open the lid 3. When the lid 3 is closed, the covering-opening portion 38a on the front side acts to magnetically attach the magnetically attached portion 7 through the magnetic force, and the centrifugal force generated by the closing action of the lid 3 also allows the lock plate 5 to naturally slide to the front sliding position.

[0039] Next, the lock plate 5 will be described with reference to Figures 8 and 9. The lock plate 5 has a convex plate body 40, an operating part 41 that protrudes upward from the front edge of the plate body 40, a magnetically attached part 7 located on the back side of the operating part 41, and leg-like locking pieces 50, 50 that protrude from both sides below the plate body 40.

[0040] The lock plate 5 is inserted into the plate accommodation space S2 of the plate accommodation body 4. In the accommodated state, the magnetically attached portion 7 of the lock plate 5 slides along the thick-groove-shaped magnetically attached portion sliding guide 33 of the plate accommodation body 4 between the front side and the back side, allowing for planar movement of the lock plate 5 itself.

[0041] The magnetically attachable portion 7 is located on the back side of the center position in the left-right direction, which is the protruding portion of the convex-shaped plate main body 40, and is made magnetically attachable to the magnet 6 by hammering metal rivets into circular recesses formed on the top and bottom. In this embodiment, rivets are used, but a circular magnet may also be inserted. The magnetically attachable portion 7 has a slightly curved portion 7a that protrudes from the back side edge of the protruding portion of the plate main body 40.

[0042] The operating portion 41 is formed on the front side edge of the plate main body 40, extending laterally beyond the magnetically attached portion 7, and is a member that protrudes upward. When the lock plate 5 is housed in the plate housing body 4 and attached to the lid 3 and case main body 2, the operating portion 41 is located in the space 31 of the plate housing body 4, and protrudes to a predetermined height in both the vertical direction so that the user can easily press the lock plate 5 toward the rear side. The operating portion 41 is positioned along a position that extends from the protruding edge 12a of the case main body 2 when the lock plate 5 is in the front sliding position.

[0043] Two groove-like guide grooves 42, 42 are formed on the underside of the plate main body 40, extending from the rear side to the front side on both sides of the magnetically attached portion 7. The lock plate movement guides 35, 35 of the plate container 4 are slidably fitted into these guide grooves 42, 42, and guide the lock plate 5 to prevent it from shifting left and right when it moves between the front side and the rear side.

[0044] The plate body 40 also has lateral protruding pieces 43, 43 that protrude further to the sides. The lateral protruding pieces 43, 43 are connected to the plate body 40 on the back side and have notches around them, giving them spring-like properties. The lateral protruding pieces 43, 43 abut against the lateral guides 36, 36 of the plate holder 4, and even if a force is applied that would cause the lock plate 5 to shift sideways, the lateral protruding pieces 43, 43 act like a spring, returning the lock plate 5 to its center position. When the lateral protruding pieces 43, 43 abut against the step portions 36b, 36b of the lateral guides 36, 36, they are stopped, preventing the lock plate 5 from moving too far toward the front.

[0045] The locking piece 50 of the lock plate 5 will now be described. The locking piece 50 is leg-shaped and extends downward from the underside of the plate body 40. It has a base 51 that extends vertically downward and an extended locking part 52 that extends further toward the front from the lower, front side portion of the base 51. The back surface of the base 51 forms an inclined surface 53 that slopes toward the front as it extends downward.

[0046] The engagement between the lock piece 50 and the lock piece engagement portion 14 of the case body 2 will now be described. When the lid body 3 is closed, the magnetically attached portion 7 of the lock plate 5 magnetically attaches to the magnet 6 of the case body 2, causing the lock plate 5 to move toward the front (see FIG. 1). At this time, the lock piece 50 is inserted into the lock piece engagement portion 14 of the case body 2, and the lock plate 5 moves toward the front, causing the extended lock portion 52 to be positioned in the lock piece engagement hole 14d. As a result, when an attempt is made to open the lid body 3, the extended lock portion 52 is positioned in the lock piece engagement hole 14d, which resists the opening movement of the lid body 3, thereby establishing a locked state.

[0047] The opening and closing operation and double lock function of the lid 3 of the pencil case 1 of this embodiment will now be described. As described above, the pencil case 1 has a magnet 6 disposed in the case body 2, and the lid 3 is provided with a lock plate 5 that is slidably disposed within the plate container 4. When the lid 3 of the pencil case 1 of this embodiment is changed from an open state to a closed state, the magnetically attached portion 7 of the lid 3 is attracted to the magnet 6 of the case body 2, and the centrifugal force generated by the closing operation causes the lock plate 5 to slide to the front, causing the magnet 6 and magnetically attached portion 7 to be locked.

[0048] Furthermore, when the lid 3 is closed, the locking piece 50 of the locking plate 5 engages with the locking piece engagement portion 14 of the case body 2 as described above. In other words, when the lid 3 is closed, the extended locking portion 52 of the locking piece 50 is positioned in the locking piece engagement hole 14d of the locking piece engagement portion 14, providing a second lock. If an attempt is made to open the lid 3 without sliding the locking plate 5, the extended locking portion 52 will engage with the engagement walls 14c above and below the locking piece engagement hole 14d, allowing it to be used as a locking mechanism. This double locking mechanism makes it easy to create a pencil case 1 in which the lid 3 cannot be opened or closed.

[0049] When opening the lid body 3 from a closed state, the user can easily unlock and open the lid body 3 by pushing the operating part 41 of the plate body 40 located on the front side of the lock plate 5 toward the rear side.

[0050] In other words, when the operating portion 41 of the plate body 40 is pushed toward the rear side, the lock plate 5 slides toward the rear side. This sliding of the lock plate 5 toward the rear side also moves the magnetically attached portion 7 toward the rear side, releasing the magnetic attachment with the magnet 6. Therefore, by simply sliding the lock plate 5, the user can easily release the lock and open the lid 3 of the pencil case 1.

[0051] Furthermore, the opening operation is facilitated by the inclined surface 53 on the back surface of the base 51 of the locking piece 50. That is, by sliding the locking plate 5 toward the back surface, the locking piece 50 also moves toward the back surface. At this time, the back surface of the locking piece 50 forms the inclined surface 53, so it comes into contact with the back wall 14a of the locking piece engaging portion 14. When the locking plate 5 is further slid toward the back surface from this state, the lid body 3 is pushed up along the inclined surface 53, and the magnetic adhesion is released.

[0052] As a result, when the user pushes the operating part 41 of the locking plate 5 toward the rear side, the inclined surface 53 comes into contact with the rear wall 14a, so that the lid 3 will not open simply due to the impact of the pencil case 1 being dropped. To open it, a two-stage pressing is required, with the locking plate 5 sliding further, but further sliding makes it possible to easily open the lid 3. This can be done with a single action of the user pressing the operating part 41, and the two-stage pressing is limited to the extent that there is a slight catch when pressing the operating part 41.

[0053] Furthermore, by making the back surface of the locking piece 50 an inclined surface 53 and making the inclination angle close to a right angle, it is possible to provide a pencil case 1 that further strengthens the locked state while making it easier to open the lid body 3 by sliding the locking plate 5.
