Small article case with double lock function

Abstract

To provide a small article case having a fit-in cover that can be easily opened / closed and fixed due to a double lock mechanism, where in the mechanism, the fit-in cover performs an opening / closing and fixing function by a rib lock (insertion part) moving in a certain direction.SOLUTION: A rib lock (insertion part) (1a) moves in a certain direction by a simple finger movement. When a fit-in cover is in an open state, if the rib lock (insertion part) moves along an L-shaped groove of a cover part and a mounting base groove on a rear face, a rectangular key is inserted into a notch latch at a symmetrical / opposing position, and a fit-in cover (2a) is fixed / stopped. When the rib lock (insertion part) moves in an L-shaped direction, the rectangular key is pinched between the mounting base groove on the fit-in type rear face and the notch latch, and the cover changes to a closed state. A return to the open state is achieved by moving the rib lock (insertion part), acting as a knob, backwards.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] This invention has a double-locking mechanism for snap-on lids. In the first stage, the knob reblock (insertion portion) (1a) moves in a certain direction, locking the rectangular key (1a) between the notched locks (5b) located symmetrically and oppositely on the side of the box, thereby securing the lid in a closed state. Then, in the second stage, the knob reblock (insertion portion) (1a) moves in an L-shaped direction, locking the rectangular key (1d) between the grooves in the mounting base (4b, 4c, 4d) and the snap-on lid (2b) on both sides, thereby securing the snap-on lid securely. To open the snap-on lid (2ab), the knob reblock (insertion portion) (1a) is moved in the opposite direction, releasing the two-stage locking and restoring the snap-on lid to its open state. [Background technology]

[0002] This type of lid with a lid has a metal part in the lid part (Patent Document 1-8), and "the lid is fastened to the case by providing unevenness on the mating surfaces of the case and the lid (Patent Documents 2-19, 20)." When using a clasp (Patent Document 1) or a fastening type (Patent Document 2) for a clasp purse, there is a risk that the part that fastens the lid will loosen and become easy to come off due to friction and vibration caused by the opening and closing action and movement of the lid over the years.

[0004] Application No. 07-002670 Summary of the Invention [Problem to be solved by the invention]

[0005] The opening and closing function of the box lid is performed repeatedly on a daily basis, and must be maintained at all times during transportation and movement in a variety of situations and circumstances. To achieve this, it is necessary to reduce damage and loosening due to friction, and to provide an opening and closing function with a simple operation and mechanism. [Means for solving the problem]

[0006] The snap-on lid portion (2b) has an L-shaped groove (3) and a notch lock (5ab) at the symmetrical, opposing position. A rib block (insertion portion) (1a) is inserted into the L-shaped groove (3). When the rib block (insertion portion) (1a), which acts as a knob, moves in a certain direction along the L-shaped groove (3) and the mounting base (4a) installed on the back of the snap-on lid (2b), it is inserted into the groove of the notch lock (5a) on the symmetrical, opposing side, and the first stage of fixing the snap-on lid (2ab) begins. After that, when the rib lock (insertion part) (1a) that acts as a knob moves in the L-shaped direction, the rectangular key (1d) is sandwiched from both sides between the groove and notch lock (5b) of the mounting base (4b, 4c, 4d), which is the second stage of fixation and locking, and the snap-on lid (2ab) is in the closed state. The open state of the snap-on lid (2ab) is restored by the reversal of the rib lock (insertion part) (1a) that acts as a knob. [Effects of the Invention]

[0007] This device provides a functional opening and closing mechanism for a snap-on lid (2ab). In box structures, even if the lid does not have a locking device, or even if the lid can be kept closed, it can loosen or suddenly come off over time, making it difficult to secure the lid. This device uses a snap-on lid mechanism, which secures the lid by clamping it to the four sides and includes a double-locking mechanism, simplifying the lid's opening and closing process. The rectangular key (1d) is clamped on both sides by the groove and notch (5b) in the mounting base (4), solving the problem of sudden loosening or removal of the lid due to movement or vibration. Furthermore, using wood for the reblock (insertion portion) (1a) and mounting base (4) eliminates the complicated disposal process of lid parts that would be required using metal or plastic. Furthermore, by installing a lid-integrated hinge made of wood as the hinge section that supports the snap-on lid, the entire snap-on lid box can be made out of wood, opening the way for the development of a variety of products with opening and closing lids that make use of the texture of wood.In this way, expanding opportunities for utilizing natural resources will promote the effective use of forest resources and is thought to have the effect of more actively promoting forest resource conservation activities.

[0009] The double locking mechanism described below can be installed in a variety of places, such as lids, storage compartments, containers, and boxes with snap-on lids.

[0010] In the pencil case example, a wooden lid-integrated hinge for opening and closing the snap-on lid is installed on one side of the hinge portion of the snap-on lid, and a rib lock (insertion part) (2a) that acts as a knob on one side of the lid, an attachment base (4a, 4b, 4c, 4d), and a notch lock (5ab) are provided in a symmetrical and opposing position to the rib lock, making it possible to repeatedly open and close the snap-on lid (2ab).

[0011] The embodiment of the accessory case is a case in which a wooden lid-integrated hinge is attached to a snap-on lid, and a knob reblock (insertion portion) (1a) is attached at the bottom of one of the opposing sides.

[0012] The example of the tissue box is a tissue box with a wooden lid-integrated hinge installed on one side of the snap-on lid (2ab) and a rib lock (insertion part) (1a) that acts as a knob at the bottom of the opposite side.

[0013] The example of the spaghetti box is a spaghetti box in which a wooden lid-integrated hinge is installed on one side of the snap-on lid (2ab) and a rib lock (insertion part) (1a) that acts as a knob is installed at the lower position on the opposite side.

[0014] In the example of the double door box, wooden lid-integrated hinges are installed on both sides of the two separate left and right snap-in lid sections on both sides, and a rib lock (insertion section) (1a) and mounting base (4a) are added to the lid section on one side, and a new notched stop (5ab) is added in a symmetrical and opposing position on the lid section on one side, making it possible to open and close the box like a double door.

[0015] The above are examples of the present invention and do not limit the scope or materials of implementation. Anything made within the spirit of the present invention and having equivalent effects to the present invention is within the scope of the present invention. [Explanation of symbols]

Claims

[Claim 1] The box portion is fitted with a snap-on lid with an integrated hinge mechanism, and the lid has a rig lock (insertion portion) (1a) that acts as a knob and is kept inserted into an L-shaped groove (3) installed on the top lid. The rig lock (insertion portion) (1a) moves in a certain direction, allowing the snap-on lid (2ab) to open, close, and secure. The rig lock (insertion portion) (1a) is composed of a square button (1b), a straight handle (1c), and a rectangular key (1d). A mounting base (4) is installed on the back surface of the lid (2b), and a notch lock (5b) is installed symmetrically and oppositely to the L-shaped groove (3) and mounting base (4a). The rectangular key (1d) is inserted into the notch lock (5a) on the side of the box portion to secure the snap-on lid and keep it closed. Then, when the rig lock (insertion part) (1a) that acts as the knob moves in the L-shaped direction, the rectangular key (1d) is inserted into the notch lock (5b), and the rig lock (insertion part) of the knob develops into a state where the rectangular key (1a) is sandwiched from both sides between the mounting base (4b, 4c, 4d) and the notch lock (5b), and the snap-in lid is fixed and secured without coming off.The mechanism has the characteristic that when the rig lock (insertion part) (1a) that acts as the knob is operated in reverse, the snap-in lid in the closed state returns to the open state.
