Description

  The present invention relates to a detachable peep prevention device that is carried away from a display screen of a portable electronic device when not in use and that covers and attaches the display screen when in use.

  In portable electronic devices such as a so-called smart phone having both functions of a mobile phone and its function and an information terminal, a member made of a film or a sheet is attached to a display screen called a display for protection. ing. Among them, there is a protective member that prevents a person from peeping during use to protect privacy, and is widely used.

  As a protective member for the purpose of preventing peeping, for example, there is JP-A-2002-202405. The invention of the same number is attached to the display screen of a display to prevent others from peeping, and consists of a lens film made of a polymer material and a self-adhesive layer, and the self-adhesive layer is formed smoothly with a flexible polymer. It is assumed that the attachment means is detachable with respect to the display screen. However, if the self-adhesive layer is provided on the back surface of the lens film, the transparency of the lens film is also impaired by the self-adhesive layer.

  Japanese Unexamined Patent Application Publication No. 2012-103719 discloses an image display device using a viewing angle control system having a film-form first polarizer and a second polarizer containing an absorbing dichroic substance. When this film configuration is employed for peeping prevention, the light transmittance is impaired by the polarized light, resulting in a problem that the quality of the displayed image is greatly reduced. Furthermore, it is necessary to use an adhesive material layer to affix the film on the display screen. If bubbles enter, not only can it be applied neatly, but it also affects visibility. Further, even if it is said that it can be attached and detached as described above, it is difficult to see the display screen when air bubbles, dust, etc. are mixed, so it is hardly reused and is practically disposable.

  On the other hand, in the case of portable electronic devices such as smartphones whose display screen is a touch panel, it is not preferable to cover the display screen with a protective film because it reduces the operation sensitivity at the fingertips. There are many people who do not. There are individual differences in what privacy is to be protected. However, if visibility and operability are impaired as a result of being sensitive to peeping, you will be forced to endure uselessness. Will be. In view of this, it is considered that there are many advantages in that the protective film is not always used but can be used as needed. However, in this case, it is necessary to devise a technique that makes it difficult to see the display screen by attaching and detaching the protective film.

JP 2002-202405 A JP2012-103719A

  The present invention has been made in view of the above circumstances, and the problem is that it is possible to enjoy the desired visibility and operability by covering the display screen only when it is desired to prevent peeping. It is an object of the present invention to provide a peep prevention device for portable electronic devices that can obtain the original visibility and operability by being removed and carried. Another object of the present invention is to provide a detachable peep prevention device for portable electronic devices having attachment means, which is also used when removed and carried when not in use.

  In order to solve the above problems, the present invention provides a sheet-like shape for preventing peeping by removing the portable electronic device from the display screen when not in use and carrying it while covering the display screen when in use. This device has a peek prevention function that touches the display screen on one side but does not adhere to it, and also exhibits good visibility in front view with respect to the display screen, and decreases in visibility other than front view. A sheet main body provided, and an attachment means attached to an end of the sheet main body, which is detachable from portable electronic devices, for attaching the sheet main body at a position covering the display screen. Means is provided such that a step that substantially absorbs the thickness of the attaching / detaching means is provided at the attachment end of the sheet main body so that the one surface of the sheet main body contacts.

  The device for preventing peeping in portable electronic devices according to the present invention is common to the conventional one only for the purpose of preventing peeping, but it does not hinder the original visibility and operability of portable electronic devices as much as possible. Is the biggest feature, which is unprecedented. The feature is achieved by the sheet body that contacts the display screen on one side but does not adhere. Contacting the display screen means that the sheet main body is substantially in contact with the display screen, and does not prevent a part of the sheet from floating from the display screen. This is because the best visibility and operability can be obtained if the sheet body is substantially in contact with the display screen when in use, and the visibility and operability are not affected because the sheet body does not adhere to the display screen. .

  The seat body exhibits a good visibility with respect to the display screen when viewed from the front, and has a peep prevention function that reduces the visibility except when viewed from the front. Such a peeping prevention function includes a lens film made of a polymer material, a viewing angle control by a polarizer, and other configurations as described in the above-mentioned patent documents. can do. In addition, in the case of front view, it is considered that the user's line-of-sight angle with respect to the display screen generally indicates a vertical direction, but the same can be understood in the present invention.

  The attachment means is attached to the end of the sheet body in order to attach the sheet body to a position covering the display screen, and is detachably attached to portable electronic devices. That is, the sheet main body is fixed to portable electronic devices only by this attachment means, and the sheet main body does not require any adhesiveness.

  As a device of the present invention, the seat body has a peeping prevention surface formed in a front shape substantially the same size and size as the display screen. When not in use, the seat body is attached to the portable electronic device by means of attachment. The sheet is bonded to the back surface and has a toughness that is difficult to bend by itself. The above configuration is preferable in that it is not easily bent even when removed and carried when not in use.

  The apparatus of the present invention is characterized in that a step that substantially absorbs the thickness of the attaching / detaching means is provided at the attachment end of the sheet main body so that the one surface of the sheet main body contacts the display screen. Further, it is desirable that the step that substantially absorbs the thickness of the attaching / detaching means provided at the attachment end of the seat body is set slightly smaller than the thickness of the attaching / detaching means attached to the attachment end of the seat body.

  As described above, the present invention can enjoy the desired visibility and operability by covering the display screen only when it is desired to prevent peeping. It is possible to provide a detachable peep prevention device in portable electronic devices that can obtain the performance and operability. Further, according to the present invention, it is possible to provide a detachable peep prevention device for portable electronic devices having attachment means, which is also used when removed and carried when not in use.

  Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments. FIG. 1 shows a detachable peep prevention device 10 in portable electronic devices according to the present invention. The device 10 contacts the display screen 21 of the portable electronic devices 20 but does not adhere to it. The seat body 11 having a peeping prevention function that exhibits good visibility in front view with respect to the display screen 21 and decreases in visibility other than in front view, and the seat body 11 are attached to and detached from the portable electronic devices 20 Two attachment means 12, 13 are provided for enabling attachment.

  The sheet main body 11 is composed of three parts: a peeping prevention surface 15 and end portions 14 and 16 on both sides of the sheet main body 11. Both the peeping prevention surface 15 and the end portions 14 and 16 on both sides may be formed from a single sheet, and the peeping prevention surface 15 is formed in a front shape that is substantially the same shape and size as the display screen 21. Attachment means 12 and 13 are provided on the inner surfaces of the end portions 14 and 16 on both sides, respectively.

  The peeping prevention surface 15 formed in a front shape substantially the same shape and size as the display screen 21 overlaps with the operation units 22a, 22b and the like adjacent to the display screen 21 when attached to a position covering the display screen 21. Notches 17a and 17b are provided at important points so that they do not become necessary. And the level | step differences 18 and 19 which substantially absorb the thickness of the attachment / detachment means 12 and 13 are provided in the attachment edge parts 14 and 16 of the sheet | seat main body 11 (refer FIG. 3 etc.).

  The steps 18 and 19 are desirably set to be slightly smaller than the thickness of the attaching / detaching means 12 and 13 attached to the attachment end portions 14 and 15 of the seat body 11 (see FIG. 3). By this setting, a slight gap g is formed between the inner surfaces of the attaching / detaching means 12 and 13 and the inner surface of the peeping prevention surface 15 so that the sheet body 11 is not so lifted from the display screen 15. Since the attaching / detaching means 12 and 13 are attached to the suction surface by applying pressure, the gap g is effective when the application is performed.

  For the attaching / detaching means 12 and 13, it is desirable to use an adsorbent resin sheet material made of urethane gel called a urethane adsorbing sheet. Note that the gap g is very small, and when the sheet body 11 is attached at a position covering the display screen 21, the peeping prevention surface 15 and the display screen 21 are substantially substantially in contact with each other. . Since this type of device repeatedly pressurizes when attached, the thickness of the attaching and detaching means 12 and 13 tends to decrease, but the contact state becomes stronger when the thickness decreases, so the gap g is a countermeasure. Is also effective.

  The sheet main body 11 having the above-described configuration can be formed using, as a material, a lens film made of a polymer material, a sheet having a configuration of a viewing angle control system using a polarizer, or the like. In the detachable peep prevention device 10 of the present invention, the sheet main body 11 contacts the display screen 21 on one side but does not adhere and does not cover the display screen 21 with the adhesive material layer. The degradation of image quality can be minimized. Of course, the present invention can be used for the seat body 11 as long as it is available at the present time.

  The seat body 11 has toughness that is difficult to bend by the seat body alone. Such a property is achieved by forming the sheet main body 11 to a certain thickness, and maintains flatness when not in use. For this reason, for example, it is also possible to overlap and fix to the back surface of the portable electronic device 20 by the attaching means 12 and 13 at both ends thereof (see the chain line in FIG. 3). However, it is also possible to separately prepare a plastic card having the same shape and size as the sheet main body 11 and attach it to one side with the attaching / detaching means 12 and 13 so as to be integrated into a pocket or the like.

  Said sheet | seat main body 11 can be formed in the flat form which has a level | step difference with a hot press molding technique, for example. If the urethane adsorbing sheet can be disposed in the mold in advance during hot press molding, the attachment means 12 and 13 can be attached to the sheet body 11 simultaneously with the hot press molding. In addition, an injection molding method can be selected to form the sheet body 11 having the steps 18 and 19. In addition, the sheet body 11 of the present invention may use a Panaprotect (registered trademark of Panac Corporation), which is a blue light cut anti-fingerprint protective film that is supposed to cut so-called blue light emitted from an LED light source. Is possible. However, in that case, the one without the adhesive layer is used.

  As shown in FIG. 1, the detachable peep prevention device 10 of the present invention having such a configuration is carried away from the display screen 21 of portable electronic devices when not in use. As a portable method, there is a method in which a plastic card (not shown) having the same shape and size as the seat main body 11 is prepared, and is attached to and integrated with the attaching / detaching means 12 and 13 into a pocket or the like. According to this method, since the peep prevention device 10 of the present invention and the plastic card are integrated and the rigidity is improved, it is further difficult to bend. On the other hand, as shown in FIG. 3, a method of attaching and detaching the sheet main body 11 to the back surface of the portable electronic device 20 with the attaching / detaching means 12 and 13 can be taken.

  The sheet body 11 constituting the apparatus 10 of the present invention has a toughness that is difficult to bend by itself, and even if it is carried in a pocket or the like as described above, there is no possibility of being folded or deformed. Further, as described above, when being fixed to the back of the portable electronic device 20, the portable electronic device 20 is carried together with the portable electronic device 20, so there is no risk of loss.

  In use, the detachable peep prevention device 10 of the present invention covers and attaches the sheet body 11 to the display screen 21 as described above (see FIG. 4). At this time, there is a gap g between the attaching / detaching means 12 and 13 and the display screen 21, but the gap g is very small and almost completely contacts. Therefore, the movement of the fingertip is directly transmitted to the display screen as it is, and the operation sensitivity is not lowered.

  The present invention is configured and operates in this way, and is removed from the display screen 21 of the portable electronic device 20 when not in use, so that the original visibility and operability of the device are not impaired. Since it is comfortable and can be worn by covering the display screen 21 during use to prevent peeping, privacy is not violated. In particular, attaching / detaching the detachable peep prevention device 10 to / from the portable electronic device 20 can be easily performed using the so-called urethane adsorbing sheet as the attaching / detaching means 12, 13. It can be said that there is a remarkable feature compared to the conventional one in that it can be maintained and comfortable visibility and operability are maintained and there is no problem even if it is repeated.
