Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a locking device, and more particularly to an improvement of a folding article with a locking device.

[0002]

[Prior art]

 A conventional folding device with a lock device, for example, a box-type electronic device such as a notebook computer, a PDA, and an electronic dictionary, or a box for storing gemstone jewelry, a kimono, and the like, usually has a lid or a first equivalent thereof. One end edge of the substantially flat body and one end edge of the box or the second substantially flat body corresponding thereto are pivotally contacted by a hinge so as to be foldable face-to-face, and the first substantially flat body is the second flat body. When folded on the surface of the substantially flat body, the first substantially flat body and the second substantially flat body are locked as they are by a lock device.

[0005] The conventional locking device includes, for example, a flap with a hole at an end opposite to the one end of the first substantially flat body, and an opposite end to the one end of the second substantially flat body. A projection that can be externally fitted into the hole of the flap, or a projection at the opposite edge of the first substantially planar body, and a projection at the opposite edge of the second substantially planar body. It is often seen that a groove provided with a protrusion is provided. However, since such a locking device has projections on both the front and rear sides, not only may there be a risk of being scratched or scratched by the projections, but also the appearance is not good.

[0004] Further, recently, the following new folded articles have been seen. The folded article is capable of folding the first substantially flat body face-to-face with the second substantially flat body, and further comprising the first substantially flat body as the second substantially flat body. And then rotated along the plane of the second substantially planar body. In other words, the first substantially flat body can be folded on the surface of the second substantially flat body at the front when folded, and in an inverted posture with the inner surface as the outer surface, that is, On the back, it can be folded on the plane of the second substantially planar body.

[0005] First, taking a normal box as an example, the second substantially flat body indicates a normal box, and the first substantially flat body indicates a normal lid. According to the configuration, when a sample, a wristwatch, a jewel, or the like that is neatly hooked on the inner surface of the lid is to be displayed to a customer sitting in an arbitrary direction while the lid is opened vertically, There is no need to change the sitting position or posture of any one person, and the lid is directly rotated at an arbitrary angle or the lid is rotated 180 degrees and then hooked on the inner surface of the lid. The outer surface of the lid can be folded on the surface of the box so that the jewel that is present faces upward. However, in the conventional box having the above configuration, the lid and the box can be locked as they are when the inner surface of the lid is folded on the surface of the box. When the outer surface of the lid is folded on the surface of the box, if the box is unexpectedly collided, the outer surface of the lid suddenly separates from the box and the inner surface of the lid. There is a possibility that a sample, a wristwatch or a jewelry, etc., which is stuck in order, may be disturbed or dropped out of the box.

[0008] Taking the notebook computer 9 shown in FIGS. 1 and 2 as an example, the second substantially flat body houses various devices and electronic components such as a battery, and a keyboard. Reference numeral 912 denotes a computer main body 91 such as a box having an upper surface attached thereto, and the first substantially flat body denotes a display portion 92 having a function of a lid having a display 922 as an inner surface such as an LCD panel. With the above-described configuration, when the information such as characters and figures displayed on the LCD panel 922 on the inner surface of the lid 92 is to be displayed to a person sitting in an arbitrary direction, as in the normal box, There is no need to change the sitting position or posture of any one person, and the display unit 92 can be directly rotated to an arbitrary angle. Also, when trying to input only by contact or handwriting without using the keyboard 912, especially in a place where there is no desk or table inside or outside the car, the display unit 92 is rotated by 180 degrees before the LCD panel. The back surface 923 of the display unit 92 can be folded on the surface of the computer main unit 91 such that the 922 faces upward. However, like the ordinary box, the conventional notebook personal computer 9 having the above configuration simply displays the LCD panel 922 of the display unit 92 as it is when the LCD panel 922 is folded on the surface of the computer main unit 91. When the rear surface 923 of the display unit 92 is folded on the surface of the computer main unit 91, the notebook computer 9 may unexpectedly collide with the computer 92 because the unit 92 and the computer main unit 91 can be locked. Then, there is a problem that the back surface 923 of the display unit 92 trembles on the surface of the computer main body unit 91 and flies away from the surface of the computer main unit unit 91, so that it is difficult to perform handwriting input easily. That is, the conventional folded article with the lock device has an inconvenience in use.

[0007]

[Problems to be solved by the invention]

 In view of the foregoing, an object of the present invention is to provide a locking device having a flat appearance and a good appearance when attached to two flat bodies so as to lock the two substantially flat bodies in a folded state. An object of the present invention is to provide an article with a lock device using the same.

[0008] Another object of the present invention is that the original outer surface (or back surface) of the first substantially flat body (or lid) is on the surface of the second substantially flat body (or box). When being folded, the original outer surface (or back surface) of the first substantially flat body (or lid) is the second substantially flat body (or box body) even if the folded article is unexpectedly hit. ) To provide a foldable article that does not separate from the foldable article.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present inventor has conducted intensive studies, and as a result, firstly, one end edge of the first substantially flat body and one end edge of the second substantially flat body are connected by the first substantially flat body. A folded article pivotally connected to the second substantially flat body so that the first substantially flat body can be folded face-to-face, wherein an inner surface of the first substantially flat body when folded is near an edge opposite to the one end edge of the first substantially flat body. A magnetic means mounted near the first groove in the opposite edge of the first substantially planar body and opposite to the one edge of the second substantially planar body. When the first substantially flat body is folded on the surface of the second substantially flat body, the locking means is attracted by the magnetism of the magnetic means and is attached to the inside of the edge. From inside the second substantially planar body, it protrudes into the first groove on the first substantially planar body, and locks the first substantially planar body. And an unlocking means is mounted in the opposite edge of one of the first substantially flat body and the second substantially flat body. The lock release device is provided with a lock release device, wherein the lock release device is configured to release the lock of the lock device to the first substantially flat body from outside. I do.

[0010] In the folded article with the lock device according to this configuration, the lock device is constituted by the magnetic means and the locking means. Therefore, the locking means is always held in the second substantially flat body. However, when the first substantially flat body is folded so as to approach the surface of the second substantially flat body, the inside of the second substantially flat body is attracted to the magnetism of the magnetic means. From the first substantially flat body. Therefore, in the folded article provided with such a lock device, there is no possibility that the projection is visible on the external appearance, and there is no possibility of being scratched or rubbed by the projection.

Then, after the first substantially flat body is folded to a position perpendicular to the second substantially flat body, and is rotated along the surface of the second substantially flat body, It is preferable to be configured so that it can be folded face-to-face with the second substantially flat body in the inverted posture in which the inner surface is the outer surface, and the opposite end of the one end edge of the inner surface in the reversed posture. In addition to having a second concave groove near an edge, the locking means is provided when the first substantially flat body is folded in the inverted posture on the surface of the second substantially flat body. Is attracted by the magnetism of the second substantially flat body and protrudes from the inside of the second substantially flat body into the second concave groove to lock the first substantially flat body. The locking means is configured to be able to release the locking projecting into the second groove. Is preferred. Thus, when one of the front and back surfaces of the first substantially flat body when folded is folded on the surface of the second substantially flat body, the first substantially flat body is left as it is. Since the body and the second substantially flat body can be locked, when the back surface of the first substantially flat body is folded on the surface of the second substantially flat body, the folded article may be unexpectedly folded. The back of the first substantially flat body cannot be separated from the second substantially flat body even if the second substantially flat body is hit. When such a structure of the folded article is applied to a notebook computer, if the original back surface of the display unit is folded on the surface of the computer main unit, even if the notebook computer is unexpectedly collided. Since the original rear surface of the display unit is firmly fixed to the computer main unit, the rear surface of the display unit shakes and rattles on the surface of the computer main unit, or from the surface of the computer main unit. There is no problem that handwriting can not be input easily by being skipped.

[0012] Then, from another aspect of the present invention, the present inventor further defines one end of the first substantially flat body and one end of the second substantially flat body as the first substantially flat surface. The second substantially flat body is pivotally connected to the second substantially flat body so as to be able to be folded face-to-face, and the first substantially flat body is in a posture perpendicular to the second substantially flat body. In a folded article configured to be able to be rotated along the surface of the substantially flat body, one of the front and back surfaces of the first substantially flat body when folded is the second one. A folding device with a locking device, comprising: a locking device that locks the first substantially flat body and the second substantially flat body as they are when folded on the surface of the substantially flat body. Only goods can be provided. As described above, the folded article according to this configuration, when one of the front and back surfaces of the first substantially flat body when folded is folded on the surface of the second substantially flat body, In this state, the first substantially flat body and the second substantially flat body can be locked, so that the back surface of the first substantially flat body is folded on the surface of the second substantially flat body. In the case of being folded, the back surface of the first substantially flat body cannot be separated from the second substantially flat body even if the folded article is unexpectedly collided.

[0013] At this time, it is preferable that the front and back surfaces of the first substantially flat body opposite to the one end edge have a concave groove, respectively, and the locking device is provided with the first substantially flat body. Magnetic means mounted near the concave groove in the opposite edge of the first substantially planar body; and magnetic means mounted in the opposite edge of the one end edge of the second substantially planar body. Is folded on the surface of the second substantially flat body, and is attracted to the magnetism of the magnetic means, so that the inside of the second substantially flat body and the inside of the concave groove on the relative surface of the first substantially flat body are separated from each other. And a locking means configured to lock the first substantially flat body as it is, and the first substantially flat body and the second substantially flat body. Any one of said first edges of said locking means mounted in said opposite edge and externally And an unlocking means configured to be able to unlock the flat body. Thereby, the locking means is always held in the second substantially flat body, and is folded so that the first substantially flat body comes close to the surface of the second substantially flat body. At the time of being inserted, it can be attracted by the magnetism of the magnetic means and rush into the first substantially planar body from inside the second substantially planar body. Therefore, as described above, a folded article provided with such a locking device has no possibility of being scratched or rubbed by the projection because no projection is visible on its appearance. .

The present inventor has further devised the configuration of the lock device itself based on the concept of the configuration of the folded article with the lock device. That is, in the present invention, following the folding article with the locking device, the first substantially flat body and one of the second substantially flat bodies are further locked in a state where they are folded together. Provide a locking device for locking. The lock device includes a lock body for mounting on the first substantially flat body, and a lock body for mounting on the second substantially flat body and locking the first substantially flat body via the lock body. Locking means. The lock body extends from a long flat body and edges along two longitudinal directions of the long flat body in the same direction perpendicular to the plane of the long flat body, and substantially in the middle thereof. When the first substantially flat body is folded on the surface of the second substantially flat body, the locking device includes a pair of raised walls each having an opening formed in the portion. Means between the pair of raised walls of the fixing device so that the means can be sucked into and protruded into one of the openings of the fixing device to lock the first substantially flat body as it is. The locking means is provided between a pair of raised walls of the fixing device and the magnetic means provided on the first substantially flat body. So that the lock on the first substantially flat body can be released. And an unlocking means that have been made.

When such a locking device is mounted on an article having any two substantially flat bodies, the appearance of the article is flat and good-looking, and the front and back surfaces of the first substantially flat body can be seen. In the case where one of them is folded face-to-face on the surface of the second substantially flat body, the first substantially flat body and the second substantially flat body are locked as they are. Can be.
