Description

Detailed description of the invention

  The present invention is, for example, a portable electronic device that is attached to the back of a smartphone or tablet computer and assists the holding operation so that the user can safely hold the device without accidentally dropping it and facilitate input / output operations. The present invention relates to a device gripping device.

  Conventionally, along with the spread of portable electronic devices such as smartphones and tablets, inadvertent damage accidents due to falling of the devices have frequently occurred, so various measures have been devised in order to protect the devices from falling accidents. . For example, as described in [Patent Document 1], a rotary handle with a stopper is installed in the apparatus body from the beginning. Cases where a belt-type handle is attached to the back side of a portable electronic device main body or a resin plate having an opening for one finger is fixed to a substrate via an adhesive pad portion to form a finger-through holding portion. (For example, [Patent Document 2]) Further, a finger ring is attached to a base plate via a holding portion having a rotation axis in two directions, the vertical direction and the horizontal direction, and the base plate is bonded to the portable electronic device body. The technology is widely known. However, the case of [Patent Document 1] is mainly attached to a rotary handle when carrying a heavy object, and the structure as a whole is too complicated to be expensive. In the case of [Patent Document 2], in the case of a belt-type handle, both belt end structures are each fixed to a base plate via a disk. Is questioned. Furthermore, in the case of using a substrate to which a resin plate having an opening for one finger of [Patent Document 2] is fixed, a protruding resin plate cannot be folded and a problem occurs when it is stored in a pocket. This document also describes various examples of attaching the mounting base plate to the back of the electronic device body. In either case, the shape of the finger ring is a simple circular flat plate, and the finger is actually passed through the ring. It does not take into account the load on the fingers when the

  The purpose of the present invention is to eliminate such difficulties, that is, a simple structure that does not require complicated rotating parts, stopper parts, screws and other mounting parts and tools, and the finger penetration part is a protrusion-fixed plate type Rather than being a corrugated finger ring when viewed from the side, the ring is placed on the substrate and decorative plate via a U-shaped frame, so that it can be freely placed both up and down, making it easy and inexpensive to manufacture. The finger ring portion has an inner diameter that is considerably larger than the diameter of the average finger excluding the thumb, and even if the finger is penetrated, there is a margin and the finger is not burdened. Further, since the ring is uneven so that it has a continuous sinusoidal shape when viewed from the side, if the protrusion is selected so as to hit the back of the finger, the curvature is such that the finger is not further loaded. In addition, since the adhesive layer covered with the release material is formed on the back of the substrate, it can be attached to portable electronic devices by removing the release material, so a wide range of users from infants to the elderly can be used as needed. Can be installed immediately. It is an object of the present invention to provide a portable electronic device gripping instrument having a finger ring portion and an adhesive pad portion that are safe, simple and inexpensive and have a finger holding effect that is reliable.

  According to the first aspect of the present invention, the finger ring portion made of metal, wood, thermoplastic resin material, thermosetting resin material, or the like is rotated to the substrate portion and the decorative plate portion via the U-shaped frame portion. The electronic device main body is damaged on the back surface of any portable electronic device by forming an adhesive pad portion with a protective sheet on the back surface of the back surface layer portion of the substrate portion. It is possible to adhere or peel without any trouble. At both end portions of the U-shaped frame portion, there are metal pieces for attachment, and they are detachably fixed to the substrate portion through the decorative plate portion, so that the finger ring can be easily attached or replaced. Further, the front shape of the finger ring portion is a substantially round shape, but the side surface shape is formed in a continuous shape of a sine wave and has an uneven portion, so that it is easy to pick up the ring portion and easily penetrate the fingers. . Further, since the finger ring portion is not fixed by a rotating shaft, a rotating pin or the like, the problem can be solved by being able to freely rotate in the circumferential direction or undulate on the back of the device.

  According to the second aspect of the present invention, when r is the average outer diameter of the finger excluding the thumb in an adult male, the inner diameter R of the finger ring portion is in the range of R = 1.2r to 2.0r. If the side surface shape of the finger ring portion is shown by a side development view, it is composed of a sinusoidal curve of Y = A Sin2θ. At this time, the vertical axis Y, the horizontal axis X, and the amplitude A = 1 / 10r. The problem is solved by being in the range of ˜1 / 2r.

  That is, according to the present invention, each part excluding the portable electronic device gripping tool body mounting bracket can be molded from various materials such as wood, leather, metal, resin, etc., so that it is extremely easy and inexpensive to manufacture and can be easily processed. It is. Furthermore, the finger ring part can be freely formed into a prototype with an arbitrary sine curve after a substantially circular shape is punched out from a flat plate material by heat processing or pressure processing, and can be processed freely according to material selection It has the characteristics that can be done. Therefore, it is easy to change the specifications according to various demands of demand because it is only attached to the substrate and the decorative plate with the adhesive layer on the back side through the U-shaped frame part, and naturally it should have more decorative properties. You can also.

  As described above, the portable electronic device gripping device of the present invention supports not only elderly people with weakened hand muscle strength but also portable electronic devices with few clues, such as mobile phones and tablet computers, supported only by fingers. In this case, since it can be easily adhered to the back of the device used, the visual recognition behavior such as confirmation and input is extremely easy, and the operation processing effect can be enhanced. In particular, the finger ring part is 1.2 to 2.0 times the average outer diameter of an adult finger in its inner diameter, and the ring part itself is composed of a sinusoidal curve, so that the load on the holding finger is not loaded. It's hard to get involved and easy. In addition, since this product is inexpensive, compact, and lightweight, it is easy to prepare for many educational facilities that are intended for various users, and it is safe and simple considering the usage conditions of a wide range of users. It is simple and extremely effective as a gripping aid that provides a gripping effect effective as a reliable portable electronic device gripping tool.

  In addition, the portable electronic device gripping device of the present invention not only holds electronic devices, but also can be carried with an adhesive layer behind a small portable item such as a cosmetic compact, pass case, business notebook, etc. It is also extremely effective for enhancing. Furthermore, since it can be manufactured at a relatively low cost, it can be used as an advertising tool for companies and the like, and it is simple and extremely effective in daily life.
