With reference to the drawings will be described a preferred embodiment of the present invention mobile phone cradle.

First, a configuration of a mobile phone holder according to an embodiment of the present invention will be described.

The mobile phone holder is formed by sequentially stacking and combining an elastic member 2, a spin housing 3, a spin member 4, and a display unit 6 on the upper surface of the base 1. The mobile phone holder has an approximately cylindrical shape. This is because the mobile phone holder is relatively safe because the risk of injury to the user is reduced because the mobile phone holder is not angular in any direction and has a cylindrical shape, and it is easy to pinch between fingers.

2, the base 1 has a circular disk shape. An insertion hole (1a) is formed in the center of the base (1), and a part of the elastic member (2) is inserted into the insertion hole (1a) to be coupled. A protruding portion 1b is formed at the edge of the insertion hole 1a to protrude, and a locking protrusion 1c is formed at the tip of the protruding portion 1b toward the inside of the insertion hole 1a. The locking protrusion 2e of the elastic member 2 is hooked and fixed to the locking protrusion 1c.

An attachment surface (1') is formed on the rear surface of the base (1). The attachment surface 1'attaches the mobile phone holder to a mobile phone or a case of a mobile phone. The attachment surface 1 ′ is formed to have adhesiveness, and a release paper for protecting the attachment surface 1 ′ may be attached to the attachment surface 1 ′. When the release paper is removed and the attachment surface 1'is adhered to the rear surface of the mobile phone or the case of the mobile phone, the mobile phone holder is fixed to the rear surface of the mobile phone or the case of the mobile phone.

The attachment surface 1 ′ is not limited to bonding, and various types of bonding may be performed. For example, the attachment surface 1'may be attached to the rear surface of a mobile phone or a mobile phone case by an adsorption method. Alternatively, the attachment surface 1'itself is formed integrally with the mobile phone case, and the mobile phone holder and the mobile phone may be combined by inserting the mobile phone case into the mobile phone.

3 and 4, an elastic member 2 is coupled to the base 1. The elastic member 2 includes a holding portion 2a, a bellows portion 2c, and an insertion portion 2d. The holding part 2a is formed in a ring shape. The holding part 2a always maintains its shape even when the elastic member 2 is unfolded or folded. When the bellows portion 2c is folded to shorten the length, the bellows portion 2c is sequentially folded in a concentric circle and aligned to the inside of the holding portion 2a.

A plurality of coupling holes 2b are formed in the holding part 2a along the circumferential direction of the holding part 2a. Part of the spin housing 3 is coupled and fixed to the coupling hole 2b. In addition, when the bellows part 2c is folded, the coupling hole 2b may also serve as an air outlet through which the air collected in the bellows part 2c escapes.

The bellows portion 2c is formed integrally with the holding portion 2a, and may be extended or reduced in the longitudinal direction. The bellows portion 2c is formed of a material having a restoring force. The bellows portion 2c may be formed to be easily inserted between fingers by concave in the center of the approximately. The bellows portion 2c is formed to decrease in diameter toward the base 1. In the process of folding the bellows portion 2c in multiple stages, each portion that is folded in a concentric circle is seated on the inside of the holding portion 2a.

An insertion portion 2d is formed at the tip of the bellows portion 2c. The insertion portion 2d has a locking protrusion 2e coupled to the base 1 in the radial direction at the tip edge. When the insertion part (2d) is inserted into the insertion hole (1a) of the base (1), the locking protrusion (2e) and the locking protrusion (1c) interfere with each other so that the elastic member (2) and the base (1) Are combined with each other.

The spin housing 3 is coupled to the holding part 2a of the elastic member 2. The spin housing 3 has a circular disk shape and a through hole 3a is formed in the center thereof. Since the bearing 3'is seated in the through hole 3a, the spin housing 3 preferably has a predetermined thickness. A seating end 3b protrudes toward the center of the through hole 3a inside the through hole 3a. The bearing 3'is seated on the upper end of the seating end 3b, and the outer peripheral surface of the bearing 3'is in close contact with the inner peripheral surface of the through hole 3a.

An engaging leg 3c protrudes from the outer peripheral surface of the spin housing 3 in the radial direction. The coupling leg (3c) is inserted into the coupling hole (2b) formed in the holding part (2a) to couple the spin housing (3) and the elastic member (2).

The spin member 4 and the spin shaft 5 are coupled to each other in a direction facing each other toward the center of the bearing 3'. The spin member 4 has a circular disk shape. The spin member 4 is installed to be spaced apart from the spin housing 3 by a predetermined distance. This is because when the spin member 4 comes into contact with the spin housing 3, frictional force acts while the spin member 4 rotates, preventing the spin member 4 from rotating.

A shaft receiving portion 4a protrudes from the center of the spin member 4. It is preferable that the shaft receiving portion 4a has a sufficient length so that the spin housing 3 and the spin member 4 are installed to be spaced apart. Specifically, the length of the shaft receiving portion (4a) is preferably formed to be longer than the thickness of the spin housing (3). The shaft receiving portion 4a protrudes in a hollow cylindrical shape and forms a concentric circle with the center of the spin member 4. The outer surface of the shaft receiving part 4a is inserted into the inner circumferential surface of the bearing 3'to make rolling contact. That is, since the shaft receiving portion 4a is in rolling contact with the inner surface of the bearing 3', the spin member 4 can rotate relative to the spin housing 3.

The spin shaft 5 may be further coupled to the inner side of the shaft receiving part 4a. The spin shaft 5 is composed of a rod portion 5a and a head portion 5b, and has a shape similar to that of a commonly used bolt. The spin shaft 5 is coupled to the inner side of the shaft receiving portion 4a by force fitting. Alternatively, a screw thread may be formed on the outer surface of the rod part 5a to be screwed with the shaft receiving part 4a. The spin shaft 5 serves to fix the spin member 4 so that the head portion 5b is hung on the bottom surface of the spin housing 3 so that the spin member 4 is not separated from the spin housing 3. In detail, the rotating shaft is coupled to the shaft receiving part 4a by force fitting, and the outer surface of the shaft receiving part 4a is in rolling contact with the inner circumferential surface of the bearing 3'. Accordingly, when the spin member 4 rotates relative to the spin housing 3, the spin shaft 5 also rotates together with the spin member 4. At this time, the spin shaft 5 is the spin housing due to the centrifugal force generated while the spin member 4 rotates because the pin head spans the lower end of the bearing 3'or the lower end of the spin housing 3 (3) It prevents deviation from.

A display portion 6 is formed on a surface of the spin member 4 opposite to the surface on which the shaft receiving portion 4a is formed. Printing paper on which letters or images are displayed may be attached to the display unit 6, or lighting and a display may be attached. An image or an image is output through the display unit 6 to increase the design of the mobile phone holder or to be used to advertise a specific product or brand.

The display unit 6 may be interlocked with the rotation of the spin member 4 to output an image. In this case, a space may be further secured inside the spin shaft 5 or inside the spin housing 3 to further install a substrate and a gyro sensor. The gyro sensor may sense the rotation of the spin member 4 and output a preset image or lighting pattern through the display unit 6.

For example, the image output on the display unit 6 may vary according to the measured RPM of the spin member 4, or the image output on the display unit 6 may vary depending on the presence or absence of rotation. In addition, components additionally required for outputting an image or illumination to the display unit 6 may be mounted between the base 1 and the attachment surface 1 ′ or inside the spin member 4.

In addition, a plurality of LEDs may be installed on the outer surface of the spin housing 3. The LED may change the lighting pattern according to the rotation value (RPM) of the spin member 4 measured by the gyro sensor installed in advance.

In addition, a speaker may be further formed inside the spin housing 3. The speaker may output sound when the gyro sensor detects rotation.

The display portion 6 is formed flat. When the display part 6 is placed on the floor and the bellows part 2c of the elastic member 2 is stretched and the mobile phone is inclined, the mobile phone can be mounted on the ground.

Stoppers (7, 8, 9) may be further provided to arbitrarily stop the rotation of the spin member (4). The stoppers 7, 8 and 9 stop rotation of the spin member 4 by providing a frictional force to the spin member 4 and a braking force. The stoppers 7, 8, and 9 may provide braking force to the spin member 4 in various ways.

In Figure 5, as an embodiment of the stopper, a disc-shaped clip 7 is shown. An insertion channel 7a is formed in the clip 7 in a straight line toward the center of the disk. The clip 7 is inserted into the insertion channel 7a so that the shaft receiving portion 4a of the spin member 4 is coupled, and is coupled between the spin housing 3 and the spin member 4. When the clip 7 is coupled between the spin housing 3 and the spin member 4, a braking force on the spin member 4 rotates by contacting one surface of the clip 7 with the spin member 4 And the spin member 4 stops.

A gripping portion 7b protrudes from the edge of the clip 7. The user may hold the grip portion 7b by hand and remove the clip 7 between the spin member 4 and the spin housing 3.

In FIG. 6, as an embodiment of the stopper, a stop pin 8 is shown. The stop pin 8 is coupled to the spin shaft 5 and protrudes toward the elastic member 2. When the spin member 4 rotates, the spin shaft 5 and the stop pin 8 also rotate.

When the bellows portion 2c of the elastic member 2 is unfolded, the stop pin 8 does not prevent the spin member 4 from rotating. However, when the bellows part 2c of the elastic member 2 is folded, the bellows part 2c draws a concentric circle and is folded and seated in the holding part 2a, and the insertion part 2d is stopped. A braking force is transmitted to the spin member 4 by contacting the pin 8, and the spin member 4 stops.

7 shows a movable member 9 as an embodiment of the stopper. The movable member 9 is separated so that a part of the spin housing 3 can move up and down. In more detail, the movable member 9 is formed by dividing the outer portion of the spin housing 3 into a ring shape. The movable member 9 has a plurality of movable pins 9a formed toward the spin housing 3, and a movable rail 9b coupled to the spin housing 3 so that the movable pin 9a can move is provided. Is formed. The movable rail 9b is formed in a spiral shape to form a path so that the movable member 9 does not directly rise vertically.

For example, when the movable rail 9b is formed in the right-hand direction and the movable member 9 is rotated to the right, the movable member 9 moves toward the spin member 4. When the movable member 9 comes into contact with the spin member 4, a braking force is transmitted to the rotating spin member 4, and the spin member 4 stops.
