Description

  The present invention relates to portable devices having various operation functions on the surface side, such as devices having personal computer functions such as mobile phones and smartphones and tablet terminals (hereinafter collectively referred to as portable devices). The present invention relates to a portable device cover that enables operation of the device surface in a stable state without dropping even when used.

  In the case of a portable device having a relatively short width, there are many usage forms in which a screen or the like is operated with one hand, and there is a possibility that the hand may be slipped or damaged due to some impact. In order to prevent such damage, the portable device main body is connected to the body, a bag, etc. with a string-like object such as a hanging strap, or is prevented from falling by careful operation using both hands.

  Despite being a portable device that can be damaged by dropping, it can only be prevented from falling by supporting it as described above. In many cases, it was forgotten to connect, or the string was disconnected or cut. In addition, there are many cases in which one hand cannot be used because it supports a suspended leather, and it is unavoidable that only one hand is required.

  On the other hand, as disclosed in Patent Document 1 described below, a frame-shaped protective cover formed of an elastic body is provided so as to cover an outer edge portion of a terminal device for the purpose of mitigating impact when dropped. However, this is based on the premise of falling and was not a technique for preventing the fall.

  Further, as in Patent Document 2 described below, a technique for holding a book by providing a pocket for inserting a finger in the outer surface portion of the book cover is known, but it is similar to a portable device that is a subject of the present invention. Since it is a precision instrument and does not require the operation of operating those screens etc. with the thumb, the reader of the book only needs to be able to support the weight of the book by hand, and the pocket only fixes the finger. It is a technology, and it is not necessary to take into account the specification of the position of attaching the pocket to the cover and the specification of the shape of the pocket, which are necessary for operating the surface side with a finger other than the holding finger. The page turning etc. should have been done with the finger of the other hand side. Further, it is sufficient that the book can be supported by the entire finger or the entire palm, and it is not necessary to strongly support the book on the fingertip side. As a supporting means with one hand accompanied by the operation of the portable device of the present invention, the abdomen side of the finger There was no need to support the back of the finger and the back of the finger with the pressing force on the lower and upper walls of the pocket.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  Fig.1 (a) has shown the perspective view of the portable apparatus cover of this invention. The portable device cover 1 is integrally attached to the main body by covering the back side and the side surface of the portable device A, and includes the back surface 2 and the four side surfaces 3, 4, 5, and 6 as necessary. Correspondingly, the flanges 7, 8, 9, and 10 projecting from the upper edge of the four side surfaces to the front surface side are provided, and the back surface 2 has at least three finger insertion portions 11, 12, as shown in FIG. 13 is provided.

  Since the portable device cover 1 can cover at least the entire back surface and the entire side surface of the portable device A, it is effective for preventing damage and contamination of the back surface and the side surface of the portable device A that is easily damaged. .

  Further, by forming the four side surfaces 3, 4, 5, and 6 from a flexible material, as shown in FIG. 1B, the portable device A can be closely attached and dropped off. However, by providing the flanges 7, 8, 9, and 10, it is possible to provide better locking means for preventing dropout. The flanges 7, 8, 9, 10 may be formed so as to protrude from the end edges of the four side surfaces 3, 4, 5, 6 over the whole, or may be formed so as to partially protrude only from the corners or the like.

  The finger insertion portions 11, 12, and 13 are individually provided on the back surface 2 from the lower side of one of the left and right longitudinal side surfaces that are the one side surface 4 toward the upper side of the longitudinal side surface 6 that is the other side surface, In addition, they are formed slightly radially so as to have a small interval between them. This is the same shape as the finger spacing in the state where the hand is widened when holding an object by hand. When holding the relatively light but heavy portable device A with one hand and operating the display on the front side with the thumb or forefinger from the top, bottom, left and right of the display surface to the back side It arranges so that it can oppose the pushing down force.

  The arrangement of the finger insertion parts 11, 12, 13 is based on the back side 2 with the lower side of one of the left and right longitudinal sides 4 as a base so that the portable device A can be stably held by the fingers inserted into them. So that the fingers in the finger insertion portions 11, 12, 13 can move in the vertical and horizontal directions so as to be able to resist the pressing force applied to the back surface 2 side. ing.

  The inclination angle θ of each of the finger insertion portions 11, 12, 13 formed slightly radially apart so as to be stably held is in the range of 15 to 40 degrees with respect to the lower edge line of the lower surface 3. The inclination angle of the finger insertion part at the upper position is slightly larger.

  FIG. 2 shows an example of the positions where the little finger insertion part 11, the ring finger insertion part 12, and the middle finger insertion part 13 are formed.

  As described above, the finger insertion portions 11, 12, and 13 not only prevent the portable device A from falling, but also various up / down / left / right directions when operating the display surface on the front side with the thumb or index finger. In order to oppose the pressing force from a certain position, a sufficient holding force is obtained on the ventral side B of the inserted finger.

  As shown in FIGS. 3 (a) and 3 (b), the insertion openings 14 of the finger insertion portions 11, 12, 13 are formed wide, and the width is formed by increasing the rising H. When each finger is inserted and the dorsal side C of the finger is brought into contact with the inner upper wall of the finger insertion portion 11, 12, 13, a gap S is formed between the surface and the back surface 2. . 3 (a) and 3 (b), the upper walls of the finger insertion portions 11, 12, and 13 are straight, but when a force is applied to the ventral side B of the finger, the dorsal side C of the finger is curved. Therefore, a material capable of forming the curved surface of the inner upper wall can be selected so as to match the curvature of the dorsal side C.

  Force with which the back side 2 of the finger is pressed strongly against the ventral side B of the last node, which is the fingertip, by applying force by bringing the dorsal side C of the finger into contact with the inner upper walls of the finger insertion portions 11, 12, 13 due to the margin of the interval S Therefore, the portable device cover 1 can sufficiently cope with not only the prevention of the portable device A from falling off but also the pressing force from the surface side.

  Even if the position of the thumb or index finger on the front side moves in the vertical and horizontal directions due to the margin of the space S, the little finger, ring finger, and middle finger inserted in each finger insertion portion 11, 12, 13 are in the vertical and horizontal directions. It is possible to follow the movement to at least the margin.

  Furthermore, the tip portions 15 of the finger insertion portions 11, 12, and 13 can be formed in a narrowed state in order to constrain the little finger, ring finger, and middle finger. Further, since there are individual differences in finger thickness, length, etc., finger restraint that can cope with individual differences by changing the protruding state of the finger from the opening by setting the tip 15 as an opening. It is possible to secure power. Furthermore, individual differences can be dealt with more reliably by forming the finger insertion portions 11, 12, 13 as a whole, particularly the distal end portion 15, with a flexible material.

  In the first embodiment, it is assumed that the left hand is used. However, the right hand is also possible. In this case, the insertion port and the tip of the finger insertion portion, the inclination angle, etc. are as shown in FIG. And a symmetrical position.

  FIG. 4 shows another embodiment of the portable device cover 16, in which the finger insertion portions 18, 19, and 20 similar to those in the embodiment 1 in which the little finger, ring finger, and middle finger can be inserted on the back surface 17 are formed. The finger insertion portions 18, 19, and 20 are embodiments in the form of a ring with a short insertion length mainly for restraining the positions of some of the little finger, ring finger, and middle finger.

  The binding force of the little finger, ring finger, and middle finger inserted into the finger insertion portions 18, 19, and 20 in comparison with that of the first embodiment is mainly the proximal portion between the base of the finger and the second joint or the second joint and the first joint. Since it is between the middle joints, the degree of freedom of movement of the finger in the vertical and horizontal directions is further increased.

  In addition, it is possible to sufficiently cope with differences in finger lengths that have individual differences.

  FIG. 5 shows another embodiment of the portable device cover 21, and finger insertion portions 23, 24, and 25 having the same shape as those of Embodiments 1 and 2 that can insert a little finger, a ring finger, and a middle finger on the back surface 22 are formed. Further, a finger insertion portion 27 for the index finger is provided at the upper end portion of the side surface 26 on each finger insertion port side.

  The finger insertion part 27 has an insertion port 28 at the lower part and a tip part 29 at the upper part. Similar to the shape of each finger insertion part in the first embodiment, the finger insertion part 27 also has a wider insertion opening side. The shape makes it easy to move up, down, left and right. Since the ventral side B of the terminal node that becomes the fingertip of the index finger is formed so that it can be pressed from the upper side from the side portion to the corner portion of the portable device A during the operation of only the thumb, the portable device A is It can be held more stably. Other shapes and the like are the same as those in the first and second embodiments.

  In FIG. 5, the shapes of the finger insertion portions 23, 24, 25, and 27 are the same as those in the first embodiment, but it is needless to say that the shape of the finger insertion portion in the second embodiment can be adopted.
