Description

The present invention relates to an anti-slip member for a portable information terminal device.

  With the recent development of portable information terminal devices, miniaturization of housings and on the other hand, displays have increased in size, and portable information terminal devices of various shapes and sizes have been announced. Under such circumstances, since a portable information terminal device such as a recent tablet PC is held with one hand and operated with the other hand, there is a problem that it is slippery from one hand and difficult to hold with one hand. In addition, the terminal is operated from an arbitrary direction, and it has become difficult to stably hold the portable information terminal device. As described above, it is forced to operate in an unstable holding state, and the problem of slipping the portable information terminal device from the hand has also been regarded as important.

  As a countermeasure, an invention has been proposed in which a portable electronic device is prevented from slipping out of a hand by sticking a leather sheet with a pressure sensitive adhesive on a portion of the portable electronic device that contacts the palm of a user's hand. (For example, refer to Patent Document 1).

  In addition, a fall prevention invention has been proposed in which a hand is inserted between a main body of a portable terminal device and a hand belt attached to the main body to encourage use (see, for example, Patent Document 2).

  In addition, a device that prevents slipping by attaching a thin rubber plate or the like to the back of the case of an electronic desk calculator (see, for example, Patent Document 3), an adhesive layer is provided on a soft member, and the mobile phone is easily damaged or slipped. An invention has been proposed in which a mobile phone can be protected and slipped by being attached to an easy place (see, for example, Patent Document 4).

  However, the thing which attached the leather sheet so that a portable electronic device may be covered like patent document 1 requires the leather sheet of the shape corresponding to the shape of a portable information terminal device, and various portable electronic devices It is difficult to provide a leather sheet having a common shape, and the shape of the portable electronic device covers the portable electronic device.

  Further, the belt-type anti-slip member as in Patent Document 2 has to be attached by processing the casing, such as screwing or brazing, and there is a problem that the anti-slip member cannot be freely attached later. It was. Further, since the holding direction is one direction, there is a problem that it cannot be held at an arbitrary position.

  Moreover, regarding the idea like patent document 3, it is a non-slip | skid member mainly aimed at the anti-slip at the time of mounting, and does not suggest the effectiveness of operation with one hand.

  The invention of Patent Document 4 is intended for mobile phones, but the shape of the anti-slip member is complex, and an anti-slip member that matches the shape of each portable information terminal device must be manufactured. It is hard to say that it can be used universally for all shapes.

  Based on the above, if the shape of the conventional anti-slip member is complicated and specialized for each case, if the shape of the portable information terminal device changes, it will not be general purpose in the rapidly changing portable information terminal industry, and it will soon become obsolete This could lead to the accumulation of defective stock. In addition, the heat dissipation effect is reduced, and the original design of the portable information terminal device is damaged.

Taking an Apple iPad (registered trademark) as an example of the portable information terminal device, it is about 190 mm × 243 mm and has a weight of 680 g to 730 g. If you try to operate a device of this size and weight with one hand, it may be difficult to hold it and slip off from your hand.
This size seems to have been optimized for book readers, which are one of the uses as portable information terminal devices, and when browsing the Internet, so it will become the standard style for similar portable information terminal devices in the future. Seem. In addition, the iPad design is very complete, and covering it with a case or cover will damage the design of the product.

  Therefore, the present invention has an object to provide an anti-slip member for preventing the mobile information terminal device from slipping out of the hand even when the mobile information terminal device is operated with one hand without impairing the original design of the mobile information terminal device. .

  In order to achieve the above object, a slip member comprising a ring-shaped member mounted on a portable information terminal device, the ring-shaped member having at least a part of a cross-section being a plane, and an adhesive layer provided on the plane. A stopper member is attached, or is fitted to a portable information terminal device without an adhesive layer.

  Since this invention is comprised as described in Claims 1 thru | or 6, there exist the following effects.

By attaching a ring-shaped member having at least a part of a cross-section to a portable information terminal as in the invention of claim 1, it functions as an anti-slip when being held by hand or placed, and is stably held Can provide status.
Furthermore, the back surface of the portable information terminal device casing when placed can be protected, and a damage prevention state and a dirt prevention state of the back surface of the portable information terminal device casing are provided.
By making the shape of the non-slip member into a ring shape, the maximum effect can be aimed at with the minimum necessary members. In other words, the portable information terminal device can be safely carried without slipping from any direction, can be operated stably when held with one hand, and the original design of the portable information terminal device is secured, The heat dissipation of the portable information terminal device is not hindered, and the manufacturing cost of the member can be reduced.

And since the shape of the non-slip member is a ring shape, the shape of the anti-slip member in a state where no external force is applied is stable, so the shape of the anti-slip member was maintained when sticking to the housing. There is also an effect that it is easy to stick as it is.
Here, when considering a circle in contact with the inside of the rectangle, the material of the member can be reduced when the inner diameter is the same because the member material is smaller than the rectangle in the ring shape rather than the rectangle.

In addition, for example, when the shape of the anti-slip member is rectangular, the force concentrates on the corner, peeling off from the corner, and the occurrence of breakage. By dispersing, it has the effect of peeling off and not causing damage.
When the shape of the anti-slip member is rectangular, when gripping the four corners of the portable information terminal device, it cannot be gripped with an equal force.

  Further, by making the cross-sectional shape of the ring-shaped member into an arc as in the invention of claim 2, 3, 5 or 6, the contact with the plane becomes a line contact, and the force applied to the ring-shaped member is dispersed and the portable information terminal There is an effect that peeling or damage from the device does not occur. In addition, when it is held with a hand, an arc having no corners has an effect that the contact with the finger is softer and easier to grip. Further, there is an effect that the ring-shaped member does not come into contact with the surface at the time of mounting, so that it is difficult to get dirt.

According to the invention of claim 3 or 6, the material of the anti-slip member is made of an elastomer or rubber, thereby generating friction with a hand or a flat surface at the time of mounting due to the characteristic of having friction resistance elasticity. The terminal device can be held without slipping.
Moreover, since it has elasticity, it can be mounted in accordance with the curved surface of the housing.

It is a front view of a non-slip member showing an embodiment of the present invention. It is the sectional view on the AA line in FIG. 1 of the non-slip member. It is a perspective view in the state where the same non-slip member was attached to the back surface of the portable information terminal device. It is an example of sectional drawing at the time of fitting the same non-slip member to the back of a personal digital assistant device. It is the figure example which attached | subjected and held | gripped the anti-slip | skid member in the back of a portable information terminal device. It is a side view in which a non-slip member is mounted on the back surface of the portable information terminal device.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 3 is a view in which the anti-slip member is attached with a double-sided tape.
Regarding the double-sided tape, in this example, since silicon rubber is used as the anti-slip member, a double-sided adhesive sheet for bonding silicon rubber was used.
The double-sided adhesive sheet is an adhesive sheet in which a silicone adhesive is applied to one side of a polyester film and an acrylic adhesive is applied to one side of the polyester film, and the sheet thickness is 0.085 mm.
When sticking, remove moisture, oil, dust, etc. on the sticking surface of the portable information terminal device with a degreasing agent or the like and stick it.

The place where the non-slip member is attached is preferably attached to substantially the center of the portable information terminal device.
For this reason, the release layer on the adhesive layer of the anti-slip member is separated into four equal parts so as to be cross-shaped so that the anti-slip member can be easily attached to the center of the portable information terminal device.
When sticking, the position of the anti-slip member is determined at the center of the information terminal device, a part of the peeling layer is removed and temporarily fixed, and the remaining peeling layer is taken and stuck so as not to distort the ring shape.
After sticking, pressure is applied evenly to the adhesion surface of the anti-slip member, and it is allowed to stand until sufficient adhesion strength is obtained.

  Further, if the sticking strength is sufficient, it is possible to use a releasable elastomer sheet and stick it to a portable information terminal device. As an advantage in that case, since it can be freely removed when using another cover or the like, the width of accessories to be attached to the portable information terminal device is widened.

In FIG. 4, it is fitted and an anti-slip member is mounted on the back of the casing of the portable information terminal device.
Also in this case, the slip prevention member may fall off if the strength is not maintained in the fitting. Therefore, the shape of the groove on the portable information terminal device side and the shape of the fitting portion of the slip prevention member should be matched to the purpose. Thus, various shapes that have been realized may be selected and used.
