1 is a perspective view illustrating a holding device for a smartphone according to a first embodiment of the present invention, and FIG. 2 is a side cross-sectional view showing a state of use of the holding device for a smartphone according to a first embodiment of the present invention.

1 and 2 , the holding device 100 for a smartphone according to an embodiment of the present invention may include a strap 110 and a support plate 120 .

The strap 110 is installed on the back of the smartphone in the vertical direction.

The strap 110 may be made of various elastic materials including a material having elasticity that can be restored, for example, rubber, silicon, or spandex-containing fibers. Therefore, the strap 110 contributes to an increase in the frictional force with the support plate 120 or the frictional force of the finger by the restoring force, thereby enabling the stable holding of the smartphone.

As the lower end of the strap 110 passes through the through hole 121 , the support plate 120 is drawn forward toward the lower part of the smartphone, and the support surface 122 of the lower part of the support plate is between the strap 110 and the strap 110 . It is supported by any one finger, for example, the middle finger, and the upper part is supported by another finger, for example, the index finger, so that it is fixed to the strap 110 to support the smartphone via the strap 110 . That is, the support plate 120 is supported by at least one finger, such as the middle finger, positioned between the support surface 122 provided to face the strap 110 at the lower side of the through hole 121 and the strap 110 . And, the upper part is supported by another finger, for example, the index finger, so that the smartphone can be supported through the strap 110 .

The support plate 120 can be moved along the strap 110 through the through-hole 121, but must maintain a state of not descending along the vertical strap 110 in a state where no external force is applied, and must be moved by hand. If you do, you should not require excessive force. In this case, the frictional force between the support plate 120 and the strap 110 may be determined by the size, number, and standard of the through-holes 121 , the distance between other through-holes 121 , the bent portion of the strap 110 , and the like.

It is used in the form of sandwiching a finger between the lower portion of the support plate 120 and the strap 110 , and when used in this way, the support plate 120 does not move and is fixed at the strap 110 . The reason for fixing the support plate 120 is the basic frictional force between the support plate 120 and the strap 110, the change in the angle generated while the strap 110 supports the finger, the increase in the frictional force generated when the finger pushes the support plate 120 out, This is due to an increase in frictional force generated when the strap 110 is stretched, a frictional force generated when a finger and the strap 110 are in contact, and the like.

On the other hand, if the gap between the through-holes 121 through which the strap 110 passes in the support plate 120 exists in the longitudinal direction of the strap 110 , it is possible to prevent the support plate 120 from being turned over during use.

When the support surface 122 and the upper part are supported by the middle and index fingers, the support plate 120 may restrict movement from the strap 110 by the frictional force with the strap 110 in the through hole 121 . That is, when the middle finger applies a force to be in close contact with the support surface 122 , and the index finger directly supports the upper part of the support plate 120 or through the strap 110 , the through hole 121 due to tensile force on the strap 110 , etc. ) due to an increase in frictional force with the strap 110 within, the movement of the support plate 120 on the strap 110 may be restricted or suppressed.

As shown in Figure 3, the strap 110, for example, both ends may be attached to the upper and lower rear of the smartphone, respectively.

As shown in Figure 4, the strap 110, as another example, both ends may be attached to the upper and lower ends of the case 20 of the smartphone 10, respectively.

As shown in FIG. 5 , the strap 110 ′ may be attached to the upper and lower ends of the attachment plate 130 having both ends attached to the rear of the smartphone 10 , as another example.

At this time, the adhesive material for attaching and fixing the strap 110 ′ may be provided on the attachment plate 130 as an example, and as another example, it may be provided on both ends of the strap 110 ′, and the attachment plate 130 and It is provided at both ends of the strap 110', or various other attachment methods may be used.

The hinge restoration part 230 allows the upper and lower sides of the support plate 220 to be folded around the horizontal hinge shaft 233, but to have a restoring force against the folding. This hinge restoration unit 230 can reduce all fingers supporting the support plate 220 causing discomfort or pain due to the weight of pressure, and between the support plate 220 and the strap 210, the fingers are excessively pressed. it can be prevented This will also work in the folding guide part, which will be described later.

The hinge restoration part 230 is provided with hinge coupling parts 231,232 for being hinged by the hinge shaft 233 on the side where the upper and lower sides of the support plate 220 are divided and contacted with each other, respectively, on the hinge shaft 233. Both ends of the spring 234 , such as a coil spring or a plate spring fitted or installed in the hinge shaft 233 or its vicinity, are respectively fixed to the upper and lower sides of the support plate 220 to provide restoring force. Here, the spring 234 is installed so as not to be easily separated from the hinge shaft 233, as in the present embodiment, to be located inside the hinge coupling part 231,232, and both ends are divided on the upper and lower sides of the support plate 220, respectively. Each is fixed to each other, and the divided upper and lower sides of the support plate 220 may provide an elastic force for returning in a direction forming the same plane.

7, the holding of the smartphone 10 will be described with reference to the holding device 200 of the smartphone according to the second embodiment of the present invention, which is not only the previous embodiment, but also all subsequent The same applies to the examples. Here, while the index finger pushes the upper part of the support plate 220 outward (c direction), the frictional force is increased in the contact range (a) with the index finger, and the middle finger is pressed in the adhesion direction between the support plate 220 and the strap 210 (d) By allowing the support plate 220 and the strap 210 to be supported with the middle finger, the friction force is increased in the contact area (b) with the middle finger, and due to these actions, the support plate 220 is fixed in the strap 210 while the smartphone ( 10) can be held. In addition, as the strap 210 is stretched, the frictional force between the support plate 220 and the finger is increased by the restoring force e due to the elastic force.

Referring to FIG. 20, as to explain the action on the frictional force between the strap and the support plate, a frictional force equal to or less than the maximum frictional force (A) in a state in which the support plate is not fixed to the strap and can be moved will act between the support plate and the strap. In this case, the support plate is moved freely from the strap in an inclined or vertical state without external force. And, when a frictional force exceeding the above maximum frictional force (A) acts between the strap and the support plate, the support plate moves along the strap by the application of an external force, the minimum frictional force in a state in which the support plate can support the weight of the smartphone In the vicinity of (B), there is an optimal frictional force section (C) between the support plate and the strap. Based on this, the stability for the support of the smartphone and the ease of movement of the support plate are inversely proportional to each other according to the magnitude of the frictional force. That is, the stability for the support of the smartphone is proportional to the frictional force, but the ease of movement of the support plate is inversely proportional to the frictional force. In this way, the process of setting the basic frictional force between the strap and the support plate within a range that can withstand the weight of the smartphone and move it without effort by hand may be obtained by simulation or experimentally.

In the present invention, regardless of whether the number of through-holes is one or more, the basic frictional force between the strap and the support plate can withstand the weight of the smartphone and can be moved by hand, so that normal use is possible. do.
