1 is a perspective view showing 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.

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

Strap 110 is to be installed in the vertical direction on the back of the smart phone.

The strap 110 may be made of a variety of elastic materials, including a material having elasticity that can be restored, for example, rubber, silicon, or a spandex-containing fiber. 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 stable holding of the smartphone.

The support plate 120 is drawn forward by passing the lower end of the strap 110 through the through hole 121 and is directed to 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 inserted into, 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 through the strap 110. That is, the support plate 120 has a support surface 122 provided to face the strap 110 at the lower side of the through hole 121 and supported by at least one finger, for example, the middle finger positioned between the strap 110 and the support plate 120 . And, as the upper part is supported by another finger, for example, the index finger, the smartphone can be supported via the strap 110.

The support plate 120 can be moved along the strap 110 through the through hole 121, but must remain in a state in which it does not descend along the vertical strap 110 in a state in which no external force is applied, and is moved by hand. If you do, you must not use excessive force. At this time, 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 the other through holes 121, the curved portion of the strap 110, and the like.

It is used in the form of putting 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 is also fixed in the strap 110 without moving. 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 angle caused by the strap 110 supporting the finger, the increase in frictional force caused by the finger pushing the support plate 120 out, This is due to the increase in frictional force generated while the strap 110 is stretched, the frictional force generated while the finger and the strap 110 are in contact, and the like.

On the other hand, if there is a gap between the through holes 121 through which the strap 110 passes through the support plate 120 in the longitudinal direction of the strap 110, the support plate 120 can be prevented from being overturned during use.

When the support surface 122 and the upper portion are supported by the middle finger and the index finger, the support plate 120 may restrict movement from the strap 110 by frictional force between the strap 110 and the through hole 121 . That is, when the middle finger applies force to be in close contact with the support surface 122 and the index finger supports the top of the support plate 120 directly or through the strap 110, the through hole 121 due to the tensile force of the strap 110 ) Due to the increase in frictional force with the strap 110 in the strap 110, the movement of the support plate 120 on the strap 110 can be limited or suppressed.

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

As shown in Figure 4, the strap 110, as another example, both ends may be attached to the top and bottom of the case 20 of the smart phone 10, respectively.

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

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 may be provided on both ends of the strap 110' as another example, and may be provided on the attachment plate 130 and Both ends of the strap 110' may be provided, or other various attachment methods may be used.

The hinge restoring unit 230 enables the support plate 220 to be folded at the upper and lower sides around the horizontal hinge axis 233, but has restoring force against folding. This hinge restoration unit 230 can reduce all fingers supporting the support plate 220 from causing discomfort or pain due to increased pressure, and the fingers are excessively pressed between the support plate 220 and the strap 210. can prevent This also acts in the same way in the folding guide portion to be described later.

The hinge restoration part 230 is provided with hinge coupling parts 231 and 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, respectively, and to the hinge shaft 233 Both ends of a spring 234 such as a coil spring or a leaf spring installed on or near the hinge shaft 233 are fixed to the upper and lower sides of the support plate 220, respectively, so as to provide restoring force. Here, the spring 234 is installed so as to be located inside the hinge coupling parts 231 and 232 as in the present embodiment so as not to easily escape from the hinge shaft 233, and both ends are respectively divided on the upper and lower sides of the support plate 220 Each is fixed, and an elastic force for returning to a direction in which the divided upper and lower sides of the support plate 220 form the same plane may be provided.

Referring to FIG. 7, the holding of the smartphone 10 will be described with reference to the smartphone holding device 200 according to the second embodiment of the present invention, which is not only the previous embodiment, but also all subsequent embodiments. The same applies to the examples. Here, the index finger pushes the top of the support plate 220 outward (direction c), increasing the frictional force in the contact range (a) with the index finger, and the middle finger between the support plate 220 and the strap 210 in the direction of close contact (d). By allowing the support plate 220 and the strap 210 to be supported, the frictional force is increased in the contact area (b) with the middle finger, and due to these actions, the support plate 220 is fixed on the strap 210 while the smartphone ( 10) to enable holding. In addition, while the strap 210 is stretched, the frictional force between the support plate 220 and the finger is increased by the restoring force (e) caused by the stretching force.

Referring to Figure 20, for explaining the action of the frictional force between the strap and the support plate, the frictional force less than the maximum frictional force (A) in a state in which the support plate is not fixed to the strap and can move is acting between the support plate and the strap. In this case, the support plate moves freely from the inclined or vertical strap without external force. And, if a frictional force exceeding the maximum frictional force (A) above acts between the strap and the support plate, the support plate moves along the strap by the application of an external force, and the minimum frictional force in a state where the support plate can support the weight of the smartphone In the vicinity of (B), an optimal frictional force section (C) between the support plate and the strap exists. Based on this, the stability of the smartphone support and the ease of movement of the support plate are in inverse proportion to each other according to the magnitude of the frictional force. That is, the stability of the support of the smartphone is proportional to the magnitude of the frictional force, but the ease of movement of the support plate is inversely proportional to the magnitude of 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 without effort by hand may be obtained through simulation or experimentation.

In the present invention, regardless of whether the number of through holes is one or multiple, 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. In fact, the friction force required to withstand the weight of the smartphone is not very high. For example, as shown in Table 1 below, if you look at the weight of major smartphones from Apple and Samsung currently on the market, most of them are in the mid-100g to 200g range. distributed between the beginnings. Even if the weight of the case is about 10 to 40 g, the weight is approximately 250 g or less, so it is enough to withstand it with the friction between the strap and the support plate.
