1 schematically shows a use state of a portable terminal holder 100 according to a first embodiment of the present invention. The structure of the portable terminal holder 100 of FIG. 1 is only for illustrating the present invention, and the present invention is not limited thereto. Therefore, the structure of the portable terminal holder 100 may be modified differently.

As shown in FIG. 1, the portable terminal holder 100 is used to mount the portable terminal P. The portable terminal holder 100 is attached to the back surface PB of the portable terminal P to support the portable terminal P so that the inclined portable terminal P does not fall. The portable terminal holder 100 is located between the portable terminal (P) and the ground (G). Here, the portable terminal (P) refers to all devices having a display (PD) while being portable, such as a smartphone and a tablet.

The portable terminal holder 100 includes a first plate-shaped portion 10, a second plate-shaped portion 20 and a support portion 30. In addition, the portable terminal holder 100 may further include other components. For example, the portable terminal holder 100 may be formed in a form including a portable terminal cover. That is, it may be manufactured integrally with a cover that wraps and protects a smartphone or tablet.

The first plate-shaped portion 10 may be attached to a back surface PB of the portable terminal P or a cover (not shown, hereinafter the same) surrounding the portable terminal P. That is, an adhesive pad (not shown) is formed on one surface of the first plate-shaped part 10 to be firmly attached to a back surface (PB) of the portable terminal P or a cover (not shown, hereinafter the same) surrounding the portable terminal P). Is attached. The second plate-shaped portion 20 is spaced apart from the first plate-shaped portion 10 along the z-axis direction and faces the first plate-shaped portion 10.

The support part 30 is manufactured integrally. That is, the support 30 may be integrally manufactured by mold-molding an elastic single material, for example, polyurethane. Polyurethanes having a hardness of 85D or 90D can be used.

 The support part 30 may be located between the first plate-shaped part 10 and the second plate-shaped part 20 to repeat contraction and elongation. Therefore, by manufacturing the material capable of exerting such a function as an integral part and manufacturing the support portion 30, it is possible to manufacture a durable component at low cost. That is, since the support part 30 is not formed by gathering several parts, there is no malfunction or the like, and its durability is excellent.

The support portion 30 is not formed of a thin film like a skin, but is made of an elastic material such as polyurethane having a thickness greater than this. For example, the thickness of the support portion 30 other than the tangential portion (not shown) that folds when the support portion 30 contracts and extends may be 1.5 mm to 1.9 mm. More preferably, the thickness of the support portion 30 other than the tangential portion (not shown) may be 1.6 mm to 1.8 mm. When the thickness of the support portion 30 is too large, not only is the material cost high, but the contraction and elongation of the support portion 30 in the z-axis direction may not be achieved well. In addition, if the thickness of the support portion 30 is too small, its durability may be deteriorated. Therefore, it is preferable to maintain the thickness of the support portion 30 within the above-described range, and as a result, the support portion 30 has a strong durability against external impact, so that the support portion 30 can be used for a long time. On the other hand, although the thickness of the support portion 30 is relatively large, the contraction and elongation of the support portion 30 is well achieved. That is, since the thickness of the tangent portion (not shown) of the support portion 30 is relatively small, contraction and elongation of the support portion 30 are free.

As illustrated in FIG. 1, the support unit 30 is extended as much as possible in the z-axis direction to hold the portable terminal holder 100 obliquely to watch a video through the portable terminal P. Conversely, in the case of carrying the portable terminal P, the support portion 30 can be contracted as much as possible in the z-axis direction and carried in a pocket or the like. Therefore, the portable terminal holder 100 has excellent portability and usability. Hereinafter, a detailed structure of the portable terminal holder 100 will be described in more detail with reference to FIG. 2.

2 schematically shows the front structure of the first portable terminal holder 100. The front structure of the portable terminal holder 100 of FIG. 2 is only for illustrating the present invention, and the present invention is not limited thereto. Therefore, the front structure of the portable terminal holder 100 can be modified to other forms.

As shown in Fig. 2, the support portion 30 has a shape that is substantially symmetrical up and down. That is, when drawing a virtual horizontal line passing through the center of the support part 30 and parallel to the xy plane, the upper and lower parts thereof have the same shape around the virtual horizontal line. Therefore, design and manufacture of the support 30 may be easy. On the other hand, the upper and lower portions of the support portion 30 may be formed differently according to sizes of the first plate-shaped portion 10 and the second plate-shaped portion 20 incorporated with the support portion 30.

The support part 30 includes a cylinder part 301, a first accommodating part 303 and a second accommodating part 305. The support 30 is formed in a hollow shape. The first receiving portion 303 connects the first plate-shaped portion 10 and the cylindrical portion 301, and the second receiving portion 305 connects the second plate-shaped portion 20 and the cylindrical portion 301. That is, the first receiving portion 303, the cylindrical portion 301, and the second receiving portion 305 are sequentially positioned from the first plate-shaped portion 10 to the second plate-shaped portion 20.

Here, the cylindrical portion 301 has a cylindrical shape whose diameter is maintained the same. The average of the cross-sectional area s303 of the first accommodating portion 303 cut in the longitudinal direction of the cylindrical portion 301, that is, in the x-axis direction, which is a direction intersecting the z-axis direction, is greater than the sectional area s301 of the cylindrical portion 301. The first receiving portion 303 includes a first diameter holding portion 3031 and a first diameter changing portion 3033. The first diameter holding portion 3031 is connected to the first plate-shaped portion 10 and has a predetermined height. The cross-sectional area of the first diameter holding portion 3031 is kept constant. The cross-sectional area of the first diameter change portion 3033 increases as it goes in the + z-axis direction. That is, the cross-sectional area (s303) gradually decreases toward the cylinder portion (301). As a result, the average of the cross-sectional area s303 of the first accommodating portion 303 is larger than the cross-sectional area s301 of the cylindrical portion 301. Accordingly, when the first plate-shaped portion 10 and the second plate-shaped portion 20 are pressed toward the support portion 30, the half of the tube portion 301 is accommodated in the first receiving portion 303, and thus the portable terminal holder 100 ) Can be reduced.

On the other hand, the average of the cross-sectional area s305 in which the second receiving portion 305 is cut in the width direction of the tube portion 301, that is, in the x-axis direction, is larger than the cross-sectional area s301 of the tube portion 301. The second accommodating portion 305 includes a second diameter holding portion 3051 and a second diameter changing portion 3053. The second diameter holding portion 3051 is connected to the second plate-shaped portion 20 and has a predetermined height. The cross-sectional area of the second diameter holding portion 3051 is kept constant. The cross-sectional area of the second diameter changing portion 3053 increases as it goes in the -z axis direction. That is, the cross-sectional area (s3053) gradually decreases toward the cylinder portion (301). As a result, the average of the cross-sectional area s305 of the second receiving portion 305 is larger than the cross-sectional area s303 of the cylindrical portion 301. Accordingly, when the first plate-shaped portion 10 and the second plate-shaped portion 20 are pressed toward the support portion 30, the half of the tube portion 301 is accommodated in the second receiving portion 305, and thus the portable terminal holder 100 ) Can be reduced.

The length of the cylindrical portion 301, that is, the length in the z-axis direction may be 6 mm to 9 mm. More preferably, the length of the tube portion 301 may be 7 mm to 8 mm. If the length of the cylinder 301 is too large, the size of the portable terminal holder 100 may be too large, which may be inconvenient to carry. In addition, when the length of the tube portion 301 is too small, it is difficult to grip the tube portion 301 by hanging a hand between the first plate portion 10 and the second plate portion 20. Therefore, it is preferable to adjust the length of the tube portion 301 to the above-described range.

3 is an exploded view of the portable terminal holder 100 of FIG. 2. The disassembled structure of the portable terminal holder 100 is only for illustrating the present invention, and the present invention is not limited thereto. Therefore, the disassembled structure of the portable terminal holder 100 can be modified to other forms.

As shown in FIG. 3, the first plate-shaped portion 10 includes an attachment plate 101 and a ring-shaped fixing portion (shown in dotted line) 103. The ring-shaped fixing part 103 is located under the attachment plate 101. The attachment plate 101 is attached to a portable terminal (not shown). To this end, an adhesive is applied to the top surface of the attachment plate 101. The portable terminal holder 100 is sold in the form of a release paper attached on the applied adhesive. Therefore, in use, the release paper can be removed and the adhesive plate 101 can be firmly attached to the portable terminal using an adhesive.

The ring-shaped fixing part 103 protrudes below the attachment plate 101 toward the cylinder part 301. The ring-shaped fixing part 103 is formed integrally with the first plate-shaped part 10. Therefore, the ring-shaped fixing part 103 does not rotate, and it is impossible to remove it from the attachment plate 101. An opening is not formed on the side surface of the ring-shaped fixing part 103 and is formed in a closed form. The ring-shaped fixing part 103 includes a plurality of protrusions 1031. The projections 1031 are radially spaced apart and protrude toward the center. The protrusions 1031 are firmly coupled with the cylinder portion 301 to closely adhere the cylinder portion 301 to the first plate-shaped portion 10.

Meanwhile, a plurality of fitting grooves 3031a are formed in the diameter holding portion 3031 corresponding to the protrusions 1031. The plurality of fitting grooves 3031a are formed to be radially spaced from each other. As shown by the dotted arrow in FIG. 3, each of the protrusions 1031 is inserted into the corresponding fitting grooves 3031a. As a result, the diameter retaining portion 3031 is firmly coupled to the first plate-shaped portion 10 and cannot be separated. Considering the size and price of the portable terminal holder 100, there is no need to separate the diameter holding portion 3031 and the first plate-shaped portion 10 from each other. Each of the protrusions 1031 and the fitting grooves 3031a has a rectangular cross section. The cross-sectional shape of the protrusions 1031 and the fitting grooves 3031a may be modified to other shapes.

As shown by the dotted arrow in FIG. 3, the first diameter holding portion 3031 contacts the attachment plate 101. More specifically, the first diameter holding portion 3031 contacts the inner surface of the ring-shaped fixing portion 103. That is, the first diameter holding portion 3031 is in close contact with the inner surfaces of the attachment plate 101 and the ring-shaped fixing portion 103, respectively, to prevent external foreign substances from penetrating into the support portion 30. Therefore, the durability of the support portion 30 can be improved. If the first diameter holding portion 3031 is formed to contact the outer surface of the ring-shaped fixing portion 103, a plurality of fitting grooves 3031a are exposed to the outside, so that foreign matter can easily penetrate into the support portion 30. In addition, the ring-shaped fixing part 103 is preferably located outside the support part 30 to hold the support part 30 during continuous contraction and elongation of the support part 30. On the contrary, when the ring-shaped fixing part 103 is located inside the support part 30, the support part 30 continuously contracting and elongating cannot be well supported.

The support portion 30 repeats contraction and elongation between the first plate-shaped portion 10 and the second plate-shaped portion 20. Therefore, when the portable terminal holder 100 is frequently used, the support portion 30 may be separated from the first plate-shaped portion 10 and the first plate-shaped portion 20. Therefore, the support portion 30 can be securely fixed between the first plate-shaped portion 10 and the first plate-shaped portion 20 through mechanical coupling in the form of fitting the protrusions 1031 into the fitting grooves 3031a. . Such a coupling structure is preferable when considering the size of the portable terminal holder 100.

Meanwhile, the second plate-shaped portion 20 includes a plate-shaped button 201 and a ring-shaped fixing portion 203. The ring-shaped fixing part 203 is located above the plate-shaped button 201 and is integrally formed with the plate-shaped button 201. The diameter of the plate-shaped button 201 is formed smaller than the diameter of the attachment plate 101. The attachment plate 101 is formed to have a relatively large area for stably attaching to the back surface of a portable terminal (not shown), but the plate-shaped button 201 is easier to grip and is not burdensome to carry. It is formed smaller than (101). To this end, the diameter of the plate-shaped button 201 may be 0.7 to 0.9 of the diameter of the attachment plate 101. The plate type button 201 may use the portable terminal holder 100 for promotional purposes by performing additional operations, such as design printing, attaching an epoxy sticker, attaching a silicone character, etc., to various effects. In addition, although the plate-shaped button 201 is shown in FIG. 3 in a circular shape, the plate-shaped button 201 may be formed in various shapes, such as a triangle, a square, or a character.

As shown in FIG. 3, the ring-shaped fixing part 203 protrudes over the plate-shaped button 201 toward the cylinder part 301. The ring-shaped fixing part 203 includes a plurality of protrusions 2031. The protrusions 2031 are radially separated from each other and protrude toward the center.

Meanwhile, a plurality of fitting grooves 3051a are formed in the diameter holding portion 3051 corresponding to the protrusions 2031. The plurality of fitting grooves 3051a are formed to be radially spaced from each other. Each of the protrusions 2031 is inserted into respective fitting grooves 3051a corresponding thereto. Each of the protrusions 2031 and the fitting grooves 3051a has a rectangular cross section. The cross-sectional shape of the protrusions 2031 and the fitting grooves 3051a may also be modified to other shapes.

As illustrated by the dotted arrow in FIG. 3, the second diameter holding portion 3051 contacts the plate-shaped button 201. In addition, the second diameter holding portion 3051 contacts the inner surface of the ring-shaped fixing portion 203. That is, the second diameter holding portion 3051 is in close contact with the inner surfaces of the plate-shaped button 201 and the ring-shaped fixing portion 203, respectively, to prevent external foreign substances from penetrating into the support portion 30. Therefore, the durability of the support portion 30 can be improved. On the contrary, if the second diameter holding portion 3051 is formed to contact the outer surface of the ring-shaped fixing portion 203, a plurality of fitting grooves 3051a are exposed to the outside and foreign matter can easily penetrate into the support portion 30. You can. In addition, it is preferable that the ring-shaped fixing part 203 is located outside the support part 30 to hold the support part 30 during the continuous contraction and elongation of the support part 30. On the contrary, when the ring-shaped fixing part 203 is located inside the support part 30, the support part 30 continuously contracting and extending cannot be well supported.

On the other hand, the length in the z-axis direction of each of the first diameter holding portion 3031 and the second diameter holding portion 3051, that is, the length in the longitudinal direction of the cylindrical portion 301 may be more than half the length of the cylindrical portion 301. have. Therefore, the cylindrical portion 301 can be completely accommodated together in the first receiving portion 303 (shown in FIG. 2) and the second receiving portion 305 (shown in FIG. 2). When the length in the z-axis direction of each of the first diameter holding portion 3031 and the second diameter holding portion 3051 is too small, full acceptance of the cylinder portion 301 is impossible. Therefore, since the thickness of the portable terminal holder 100 cannot be greatly reduced, it is inconvenient to carry. This will be described in more detail through FIGS. 4 and 5.

4 shows a state in which the half of the tube portion 301 of the portable terminal holder 100 is contracted. The operating state of the portable terminal holder 100 of FIG. 4 is only for illustrating the present invention, and the present invention is not limited thereto. Therefore, the operating state of the portable terminal holder 100 can be modified to other forms.

As shown in FIG. 4, the direction in which the first plate-shaped portion 10 and the second plate-shaped portion 20 are close to each other, that is, the first plate-shaped portion 10 is -z-axis direction, the second plate-shaped portion 20 Presses the first plate-shaped portion 10 and the second plate-shaped portion 20 in the + z-axis direction, respectively. In this case, the tangential portion 302 of the cylindrical portion 301 and the first diameter changing portion 3033 is changed to approach the first plate-shaped portion 10. Since the tangential portion 302 is formed thinner than the general thickness of the support portion 30, it acts as a starting point for folding by the pressing force. To this end, it is desirable to form the tangent portion 302 relatively thinly. When the tangent portion 302 is formed thin, the first diameter change portion 3033 may be easily flipped based on the tangent portion 302. For example, the thickness of the tangent portion 302 may be 0.5 mm to 0.95 mm. More preferably, the thickness of the tangent portion 302 may be 0.6 mm to 0.85 mm. If the thickness of the tangent portion 302 is too small, manufacturing of the tangent portion 302 is difficult and the tangent portion 302 can be easily broken. In addition, when the thickness of the tangent portion 302 is too large, the tangent portion 302 is difficult to turn over. Therefore, the thickness of the tangent portion 302 is maintained in the above-described range.

As the first diameter changing portion 3033 is recessed toward the first plate-shaped portion 10, about half of the cylindrical portion 301 is accommodated in the first receiving portion 303. That is, the first diameter change unit 3033 has a convex shape in the -z axis direction, but is convexly turned upside down in the + z axis direction or is recessed close to it to accommodate the tube portion 301.

As shown in FIG. 4, the portable terminal holder 100 may be used in a state in which only half of the portable terminal holder 100 is stretched. That is, when the portable terminal is intended to be used without placing a large slope, the portable terminal holder 100 is used by accommodating only half of the tube portion 301. As a result, the portable terminal holder 100 can be more conveniently customized. In order to accommodate the cylinder portion 301, the length 13031 of the first diameter holding portion 3031 is preferably equal to or more than half the length 1301 of the cylinder portion 301.

5 shows a state in which the support portion 30 of the portable terminal holder 100 is completely retracted. The operating state of the portable terminal holder 100 of FIG. 5 is only for illustrating the present invention, and the present invention is not limited thereto. Therefore, the operating state of the portable terminal holder 100 can be modified to other forms. In addition, since the operating state of the portable terminal holder 100 of FIG. 5 is similar to the operating state of the portable terminal holder 100 of FIG. 4, the same reference numerals are used for the same parts, and detailed descriptions thereof will be omitted.

As shown in FIG. 5, the length l3051 of the second diameter holding portion 3051 in the z-axis direction, that is, in the longitudinal direction of the cylinder portion 301, may be more than half of the length l301 of the cylinder portion 301. . Therefore, the cylinder part 301 is completely accommodated by the first diameter holding part 3031 and the second diameter holding part 3051. More specifically, as the tangent portion 304 of the cylindrical portion 301 and the second diameter changing portion 3053 approaches the second plate-shaped portion 20, the second receiving portion 305 is inverted. In addition, the cylindrical portion 301 is accommodated in the second receiving portion 305 as well as the first receiving portion 303. As a result, the thickness of the portable terminal holder 100 is minimized while the first diameter holding unit 3031 and the second diameter holding unit 3051 are in contact with each other, so that the portable terminal holder 100 can be easily carried.

Meanwhile, although not illustrated in FIG. 5, when the portable terminal holder 100 is to be extended, the first plate-shaped portion 10 and the second plate-shaped portion 20 are spaced apart from each other, that is, the + z-axis direction and −, respectively. The first plate-shaped portion 10 and the second plate-shaped portion 20 are pulled in the z-axis direction. Since the diameters of the first plate-shaped portion 10 and the second plate-shaped portion 20 are larger than the diameters of the support portions 30, the first plate-shaped portion 10 and the second plate-shaped portion 20 can be easily put into the hands. Can be pulled. As a result, the cylinder portion 301 comes out of the first receiving portion 303 and the second receiving portion 305. Through this method, the portable terminal holder 100 may be extended to the maximum to incline and secure the portable terminal.

6 schematically shows an exploded structure of the second portable terminal holder 200. The structure of the portable terminal cradle 200 of FIG. 6 is similar to the structure of the portable terminal cradle 100 of FIG. 3, so the same reference numerals are used for the same parts, and detailed descriptions thereof will be omitted.

As shown in FIG. 6, the coiled elastic member 32 may be installed inside the diameter change portion 3033 included in the first receiving portion 303. The elastic member 32 is formed in a coil shape and is in close contact with the inner surface of the diameter change portion 3033. Therefore, when the cylinder portion 301 is accommodated in the first receiving portion 303 and then taken out, it can be more easily taken out by using the elasticity of the elastic member 32. On the other hand, although not shown in Figure 6, the second receiving portion 305 can also be easily deformed using a coiled elastic member 32. As a result, the first plate-shaped portion 10 and the second plate-shaped portion 20 are pulled in opposite directions, so that the portable terminal holder 200 can be easily extended with a small force.

Hereinafter, the present invention will be described in more detail through experimental examples. These experimental examples are only for illustrating the present invention, and the present invention is not limited thereto.

Experimental example

In the case of manufacturing a portable terminal holder, elasticity of a support portion in which contraction and elongation are repeated is very important. If the strength of the support is too large, its elasticity is weak, so that shrinkage and elongation are less likely. Conversely, if the strength of the support is too small, the portable terminal holder cannot support the portable terminal well. Therefore, since the contraction and elongation of the support must be made naturally, the material and the thickness of the support are important, so an experiment was conducted.

First, two plate-shaped parts were injection molded using polyimide as a material. Then, a polyurethane chip having a hardness of 90D was placed in a mold and injection molded to produce an integral support. The shape of the integral support portion was the same as that of the support portion 301 shown in FIG. 2. After changing the thickness of the urethane and the thickness of the tangent by using various molds, the top and bottom of the manufactured support were fixed to the holder, and then the compression and elongation processes were repeated 100 times to perform shrinkage and elongation tests. It was judged whether the support portion contracted and elongated well, and whether the support portion was damaged was also observed. Such contraction and elongation tests are easily understood by those skilled in the art to which the present invention pertains, and thus detailed description thereof will be omitted.

Experiment result

The experimental results according to Experimental Examples 1 to 16 described above are summarized in Table 1 below. As shown in Table 1, in shrinkage and extensibility, it was observed that the smaller the thickness other than the tangent, the better. That is, in Experimental Examples 1 to 4, the contraction and elongation were observed to be very good, and in Experimental Examples 5 to 12, it was observed to be good. However, as the thickness of the support portion became larger, the shrinkage and elongation in Experimental Example 13 and Experimental Example 14 were somewhat stiff and evaluated as good. It was judged to be bad. Therefore, the thickness of the desired support portion excluding the tangent portion was evaluated to be 0.3 mm to 0.95 mm in Experimental Examples 1 to 14.

On the other hand, as a result of the breakage test, breakages such as tearing of the tangent in Test Examples 1 to 4 occurred. That is, the thickness of the tangential portion was too small, resulting in damage due to repeated stress. Due to such a breakage, a problem occurs in that the support portion is not well received in the first receiving portion and the second receiving portion. In addition, in the case of Experimental Example 5 and Experimental Example 6, breakage such as tearing of the tangent did not occur, but a somewhat unstable point was found. Therefore, it was evaluated as rather good. On the other hand, Experimental Example 7 to Experimental Example 16 were evaluated to be good because the thickness of the tangent portion is not broken to a certain extent.

In conclusion, as a result of conducting experiments on shrinkage and elongation and breakage, it was evaluated that Experimental Examples 5 to 14 were preferable. That is, the thickness of the support portion other than the tangent portion is preferably 1.5 mm to 1.9 mm, and the thickness of the tangent portion is preferably 0.5 mm to 0.95 mm. More preferably, Experimental Examples 7 to 12 were evaluated to be more excellent. That is, the thickness of the supporting portion other than the tangential portion is preferably 1.6 mm to 1.8 mm, and the thickness of the tangential portion is preferably 0.6 mm to 0.85 mm. Therefore, in the case of manufacturing the support portion, it was possible to manufacture the support portion of the portable terminal holder by determining the thickness of the tangential portion and the portion excluding it based on these experimental examples.
