Can rotate

By providing the horizontal rotating means and the vertical rotating means, the folder portion 1 can be opened in the horizontal or vertical direction with respect to the main body portion 2. However, the problem at this time is that when the user opens in the vertical direction when the user wants to open in the horizontal direction, or when the user opens in the horizontal direction when the user wants to open in the vertical direction, the folder part 1 is opened with respect to the main body part 2. It becomes a tattered state that can move in any direction, causing inconvenience to use. Therefore, in order to prevent such a problem, in this invention, when the folder part 1 opens more than a predetermined angle horizontally or vertically, it is preferable to provide the stopper apparatus which does not open in a different direction.

The stopper device includes a first stopper 40 for preventing the folder portion 1 from rotating in the horizontal direction, and a second stopper 50 for preventing the folder portion 1 from rotating in the longitudinal direction. The first stopper 40 is installed to move left and right in the hinge body 10, the body 41 having the seating grooves (41a, 41b) on the lower surface, and a handle protruding on one side of the body (41) It consists of 42. The handle 42 may protrude to the outside of the hinge body 10 through the hole 14 of the hinge body 10 formed at a corresponding position so that the user can selectively move the hinge body 10 in the left and right directions. . The seating grooves 41a and 41b have a stepped shape in two stages in the shape of a '-' shape. An elastic member 60a is seated on one side of the first stopper 40, and the first stopper 40 may return to its original position after moving in the horizontal direction by the elastic force of the elastic member 60a. The body 41 of the first stopper 40 is pushed to the right by the elastic force of the elastic member 60a when the handle 42 is not used. At this time, the end portion of the body 41 protrudes outward through the hole 13a formed in the inclined surface 13 of the hinge body 10 and is inserted into the hole 1c formed in the folder part 1 (see FIG. 3B). As a result, the first stopper 40 fixes the folder part 1 so that the folder part 1 cannot be opened in the transverse direction with respect to the main body part 2.

The second stopper 50 is positioned in the hinge body 10 and has a shape in which a protrusion 52 extending laterally from an upper end of the body 51 is provided. The end of the protrusion 52 is provided with a first protrusion (51a) protruding in the upward direction, the second protrusion (51b) and the third protrusion (51c) protruding laterally also in the upper and lower ends of the body (51) It is provided. The first protrusion 51a has a structure corresponding to the seating grooves 41a and 41b of the first stopper 40, and the second protrusion 51b has a groove 13b formed on the inclined surface 13 of the hinge body 10. Protruding to the outside of the hinge body 10 through the structure can be in contact with the projections (1d, 5a and 5b) of the folder (1). The third protrusion 51c has a structure corresponding to the U-shaped groove 31a formed in the protrusion 31 of the folder hinge 30.

In addition, the elastic member 60c is seated on the lower end of the protrusion 52 and the side surface of the body 51 in the second stopper 50, and the elastic member 60b is seated on the upper side of the body 51. Due to the elastic force of the elastic member 60c, the second stopper 50 can reciprocate in the vertical direction, and as shown in FIGS. 6A to 6C, the upper end of the second stopper 50 is moved by the elastic member 60b. Can rotate around the lower part.

When assembling the connecting device 3 of the clamshell mobile communication terminal which can be opened in the horizontal or vertical direction according to the present invention, the folder hinge 30, the first stopper 40 and the second stopper in the hinge body 10 are assembled. After installing the components such as the 50 and the elastic member 60, the assembly is completed by coupling the hinge body cover 11 to the hinge body 10.

Referring to Figures 5a, 5b and 6a to 6c, look at the operation of the folder-type mobile communication terminal that can be opened in the horizontal or vertical direction according to the present invention.

5A and 5B are cross-sectional views taken along the line A-A 'in FIG. 2, and FIG. 5A shows a state in which the clamshell mobile communication terminal according to the present invention can be vertically opened. Referring to FIG. 5A, the elastic member 60a is positioned on the side of the first stopper 40, and the body 41 of the first stopper 40 has a groove formed on the inclined surface 13 of the hinge body 10. It is a state inserted and fixed in the hole 1c formed in the folder part 1 through 13a). Therefore, even if the user wants to open the folder 1 in the horizontal direction, the horizontal stop means 20 cannot operate because the first stopper 40 fixes and supports the folder 1. (1) is a state which cannot be opened horizontally with respect to the main-body part 2.

A case of opening in the horizontal direction in the state of FIG. 5A will be described. When the user moves the handle 42 in the direction of the arrow in FIG. 2, as shown in FIG. 5B, the first stopper 40 is moved to the left side, and the elastic member 60a is compressed to store the elastic force. When the first stopper 40 moves to the left side, the second stopper 50 moves upward by the elastic force stored in the elastic member 60c. At this time, the first protrusion 51a of the second stopper 50, which was seated in the seating recess 41a, is also moved and seated in the seating recess 41b.

Referring to FIG. 5B, the first stopper 40 comes out of the hole 1c of the folder part 1 and the groove 13a of the hinge body 10 and no longer holds and supports the folder part 1. Therefore, the folder unit 1 is in a state that can be opened in the horizontal direction as shown by the arrow direction of Figure 5b by the horizontal rotating means (20). In addition, while the second stopper 50 moves upward, the second protrusion 51b protrudes upward from the surface 2c of the main body 2 and pushes the protrusion 1d formed in the folder part 1 upward. In addition, the folder part 1 is slightly opened with respect to the main body part 2, so that the user can easily open the folder part 1 in the horizontal direction.

At this time, in the state of FIG. 5B in which the folder part 1 can be opened in the horizontal direction, it cannot be opened in the vertical direction, so that the third protrusion 51c of the second stopper 50 is the protrusion of the folder hinge 30. 31 is engaged with and fixed to the U-shaped groove 31a formed in FIG. 31 (see FIG. 6C). As described above, the rotating shaft 32 of the folder hinge 30 is inserted into and fixed to the hole 2d of the main body 2 and As the folder hinge 30 rotates about the axis of rotation 32, the folder hinge 30 acts as a longitudinal rotation means, but as shown in FIGS. 5B and 6C, the third protrusion 51c has a U-shaped groove ( When locked in engagement with 31a), the folder hinge 30 cannot be rotated. Therefore, in the state of FIG. 5B, the folder part 1 is not opened in the vertical direction with respect to the main body part 2, and is opened in the horizontal direction only.

When the user closes the folder part 1 in the open state in the horizontal direction, the protrusion 1d formed on the folder part 1 pushes the second protrusion 51b of the second stopper 50 downward, Accordingly, the second stopper 50 moves downward again. When the second stopper 50 moves downward to some extent, the first protrusion 51a is released from the seating groove 41b and the first stopper 40 is driven by the elastic force stored in the elastic member 60a. Moves back to the right direction, and the first protrusion 51a of the second stopper 50 is seated back into the seating groove 41a to return to the state of FIG. 5A.

In addition, in the present invention, the first stopper 40 and the second stopper 50 may be fixed to prevent the handle 42 from moving when the folding mobile communication terminal is opened at a predetermined angle or more. When the folder part 1 is opened in the vertical direction, the user accidentally operates the handle 42 so that the first stopper 40 moves inward to disconnect the folder part 1 from the connecting device 3. It is to prevent that.

Specifically, FIGS. 6A to 6C are cross-sectional views in a direction BB ′ in FIGS. 5A and 5B, and FIG. 6A shows a closed state of the folder part 1, and the elastic member 60b has an upper end of the second stopper 50. Compression is installed between the portion and the hinge body 10 to store the elastic force. Although not shown in detail in other drawings, referring to FIG. 6A, a lower jaw 43 protruding downward is formed at the lower right side of the first stopper 40. Although the second stopper 50 is subjected to the force to rotate clockwise in FIG. 6A by the elastic member 60b, the third protrusion 51c is caught by the protrusion 31 of the folder hinge 30 and cannot move. to be.

When the folder portion 1 is opened about 15 ° in the longitudinal direction, the hinge body 10, the first stopper 40, and the second stopper 50, except for the protrusion 31 in FIG. 6A, are the same as the folder portion 1. It rotates 15 degrees and becomes a shape like FIG. 6B. At this time, since the protrusion 31 is relatively rotated, a space in which the second stopper 50 can move is created, and the second stopper 50, which has been subjected to the elastic force of the elastic member 60b, is attached to the hinge body 10. It is caught by the jaw 43 formed on the right side of the first stopper 40 while moving relative to the first stopper 40. When the second stopper 50 is caught by the jaw 43, the first stopper 40 may not move in the horizontal direction as shown in FIG. 5B. That is, it is fixed in the state of FIG. 4A, and the handle 42 of the first stopper 40 is also fixed and does not move. Therefore, when the folder portion 1 is opened at a predetermined angle, here about 15 ° or more, the folder portion 1 is in a state that cannot be opened in the horizontal direction.

6C illustrates a state in which the folder part 1 is opened in the horizontal direction as shown in FIG. 4B, and the third protrusion 51c is U-shaped in the folder hinge 30 while the second stopper 50 moves upward. The state engaged with the groove 31a is shown. As a result, the protruding portion 31 is caught by the second stopper 50 and cannot be rotated, and the folder portion 1 is in a state in which it cannot be opened in the vertical direction.

As described above, the folding type mobile communication terminal which can be opened in the horizontal or vertical direction of the present invention can be operated so as to be opened in only one of the horizontal and vertical directions by providing a stopper. In addition, the mobile communication terminal according to the present invention can be designed so that it can not be opened horizontally when opened vertically more than a predetermined angle.

The present invention is not limited to the described embodiments, and various modifications and changes can be made to those skilled in the art without departing from the spirit and scope of the present invention. Such modifications or modifications may be made to the present invention. It belongs to the claims of the.
