1 to 11, a cradle 100 of a portable terminal according to an embodiment of the present invention includes a mounting plate 110 for mounting a portable terminal such as a tablet computer.

The mounting plate 110 may be formed flat to mount a portable terminal (not shown), and may be formed to prevent the portable terminal from slipping or falling when tilted within a set angle. Of course, the mounting plate 110 can be applied in various shapes and various materials.

In particular, the mounting plate 110 can be tilted and supported so that the portable terminal can be easily seen or used by the user.

Thus, the holder 100 according to the present invention includes a supporting beam 120, a bracket 130, and a tilting unit 200.

The supporting beams 120 are disposed side by side relative to the floor to support the mounting plate 110. At this time, one or more supporting beams 120 may be provided. For convenience, one supporting beam 120 is provided.

In addition, the supporting beam 120 may be divided into the enlarged diameter portion 122 and the reduced diameter portion 124 along the axial direction to set the installation position of the tilting portion 200. The enlarged diameter portion 122 is formed to have a relatively large diameter in order to maintain or increase the supporting force with respect to the mounting plate 110 and the reduced diameter portion 124 has a relatively large diameter to form the step portion 210 As shown in Fig. Particularly, since the tilting portion 200 is disposed on the reduced diameter portion 124, the volume of the tilting portion 200 can be reduced.

Of course, the diameters of the enlarged diameter portion 122 and the reduced diameter portion 124 are variously applicable.

The bracket 130 is coupled to the mounting plate 110 after wrapping the supporting beam 120 and the tilting unit 200. Therefore, the bracket 130 can play a role of maintaining connection between the mounting plate 110 and the supporting beam 120, and can protect the tilting unit 200.

At this time, the bracket 130 includes a base plate 132 and a housing 134.

The base plate 132 is detachably coupled to the lower surface of the mounting plate 110 by a bolting or other fastening element. The base plate 132 is formed to be able to insert the reduced diameter portion 124 of the supporting beam 120 in the axial direction.

Accordingly, the corresponding components of the tilting part 200 provided in the reduced diameter part 124 are disposed and protected inside the base plate 132 into which the reduced diameter part 124 is inserted. That is, the base plate 132 forms a mounting hole portion 136 that opens to both sides along the axial direction on the lower side. The corresponding components of the reduced diameter portion 124 and the tilting portion 200 are provided inside the mounting hole portion 136.

Of course, the base plate 132 can be applied in various shapes and various materials.

The housing 134 covers the base plate 132 and protects the base plate 132. In addition, the housing 134 forms an opening 138 corresponding to the open side of each of the mounting holes 136. Thus, the supporting beam 120 is inserted into the mounting hole portion 136 through the opening 138 of the housing 134. At this time, the supporting beam 120 is assembled to the bracket 130 so as to be exposed to both sides of the base plate 132 and the housing 134.

In particular, the housing 134 is detachably coupled to the base plate 132 with the base plate 132 wrapped around it. In particular, the housing 134 is formed to maximize the interior sensation while surrounding the base plate 132.

At this time, the supporting beams 120 are inserted into the housing 134 so as to be exposed to both sides of the housing 134.

In addition, the base plate 132 and the housing 134 can be detachably coupled in various ways.

For example, the base plate 132 forms binding ribs 133 at least on both side edges or at least both side edges thereof, and the housing 134 forms binding holes 135 in a one-to-one correspondence with the binding ribs 133.

The coupling rib 133 is slidably inserted into the coupling hole 135 so that the base plate 132 moves axially inside the housing 134 and then is coupled to the housing 134. [

Of course, the binding rib 133 and the binding opening 135 can be deformed into various shapes.

The tilting unit 200 is disposed inside the receiving groove of the bracket 130 and in particular the base plate 132 so as to guide the tilting of the mounting plate 110 in the circumferential direction with respect to the supporting beam 120, .

In detail, the tilting unit 200 includes a step unit 210, a first tilting bush 220, a second tilting bush 230, a tilting compression elastic member 240, and a tilting pin member 250.

The stepped portion 210 is formed at a position separating the reduced diameter portion 124 of the supporting beam 120 from the enlarged diameter portion 122.

The first tilting bush 220 is axially inserted into the reduced diameter portion 124 and is moved along the axial direction of the reduced diameter portion 124. The first tilting bush 220 is adjacent to the stepped portion 210 or abuts on the stepped portion 210 do. Thus, the first tilting bush 220 is fixed to the corresponding position of the reduced diameter portion 124.

The first tilting bush 220 is formed in a substantially conical shape gradually increasing in diameter from the reduced diameter portion 124 toward the enlarged diameter portion 122 to press the base plate 132 of the bracket 130. That is, the first tilting bush 220 presses the inner surface of the mounting hole 136 of the base plate 132 in the circumferential direction while being inserted into the reduced diameter portion 124 to be supported by the step portion 210. Thus, the mounting plate 110 is firmly supported on the first tilting bush 220, thereby preventing any arbitrary rotation in the circumferential direction with respect to the supporting beam 120.

In particular, the first tilting bush 220 can be applied to various materials such as elastically deformable materials, and can be deformed into various shapes.

In addition, the second tilting bush 230 is inserted to be fixed at the end of the reduced diameter portion 124. At this time, the second tilting bush 230 is formed in a substantially conical shape in which the diameter gradually increases in the direction of the end of the reduced diameter portion 124. That is, the second tilting bush 230 is formed to be inclined so that the circumferential surface gradually rises in the direction of the end of the reduced diameter portion 124. The mounting hole 136 of the base plate 132 forms a supporting slope 137 on the inner surface corresponding to the second tilting bush 230. The supporting slopes 137 are symmetrically formed on the inclined circumferential surface of the second tilting bushes 230 and are mutually interviewed. Thus, the second tilting bush 230 is prevented from moving toward the step portion 210 along the reduced diameter portion 124.

The second tilting bush 230 is formed in a substantially conical shape whose diameter gradually increases in the direction of the end of the reduced diameter portion 124 so that the inner surface of the mounting hole portion 136 of the base plate 132 is pressed in the circumferential direction do. Thus, the mounting plate 110 is firmly supported on the second tilting bush 230, thereby arbitrarily preventing arbitrary rotation in the circumferential direction with respect to the supporting beam 120.

Of course, the second tilting bush 230 can be applied to various materials such as elastically deformable materials, and can be deformed into various shapes.

The tilting compression elastic member 240 elastically presses the second tilting bush 230 toward the step 230 on the side of the end of the reduced diameter portion 124. That is, the tilting compression elastic member 240 is axially inserted into the reduced diameter portion 124 so that one side of the tilting compression elastic member 240 is resiliently supported by the second tilting bush 230. Here, the tilting compression elastic member 240 can be applied as a compression coil spring for inserting the edge of the reduced diameter portion 124 corresponding to the second tilting bush 230 to the end.

The tilting clamp member 250 is screwed to the end of the reduced diameter portion 124 to adjust the degree of compression of the tilting compression elastic member 240.

That is, when the tilting clamping member 250 is screwed into the reduced diameter portion 124 and inserted further, the tilting compression elastic member 240 moves the second tilting bush 230 by the urging force of the tilting clamp member 250 And is further pressed toward the first tilting bush 220 side. The tilting compression elastic member 240 is pressed against the inner surface of the mounting hole 136 of the base plate 132 by the peripheral surface of the second tilting bush 230, The pressing plate 110 is arbitrarily prevented from rotating in the circumferential direction in the supporting beam 120 by increasing the pressing force for pressing the tilting clamp member 250. [

In particular, the tilting clamp 250 may have a tilting washer 252 at one side thereof to elastically support the tilting compression elastic member 240 stably.

At this time, there is a high possibility that the first tilting bush 220 and the second tilting bush 230 are damaged by pressing the inner surface of the mounting hole 136.

In order to prevent this, the tilting unit 200 may include a first tilting reinforcing member 260 and a second tilting steel member.

The first tilting bushing 260 covers the first tilting bush 220 to reinforce the rigidity of the first tilting bush 220. In addition, the first tilting bushing 260 may be made of a material having rigidity higher than that of the first tilting bush 220. The first tilting bushing 260 is formed with an inclined circumferential surface like the first tilting bush 220 to press the inner surface of the mounting hole 136.

Likewise, the second tilting bushing 230 serves to enclose the second tilting bush 230 to reinforce the rigidity of the second tilting bush 230. The second tilting bushing 230 is made of a material having a stiffness higher than that of the second tilting bushing 230. The second tilting bushing 230 is formed to have an inclined circumferential surface like the second tilting bushing 230, The first tilting reinforcing member 260 is prevented from moving toward the first tilting reinforcing member 260 while being pressed against the inner surface of the mounting hole 136 by being in contact with the support tilting surface 137 formed symmetrically to the first tilting reinforcing member 260.

Of course, the first tilting reinforcing member 260 and the second tilting reinforcing member 270 can be deformed into various shapes.

As a result, the mounting plate 110 is tilted by a pressing force by a force that the user attempts to rotate the mounting plate 110 in the circumferential direction with respect to the supporting beam 120.

The first tilting bushing 220, the first tilting reinforcing member 260, the second tilting bush 230 and the second tilting reinforcing member 270 are disposed on the inner surface of the mounting hole 136 of the base plate 132 By the pressing force, the mounting plate 110 is arbitrarily tilted in the circumferential direction with respect to the supporting beam 120.

In addition, the enlarged portion 122 of the supporting beam 120 may be located on the right side of the user or on the left side. In this case, the mounting plate 110 should maintain the same direction with respect to the user.

To this end, the first tilting bush 220 and the second tilting bush 230 are partially exposed to the outside of the mounting hole 136, and a stopping protrusion 282 protrudes from the circumferential surface.

The base plate 132 forms a stopping groove portion 284 at the same position on both side edges of the mounting hole portion 136. At this time, the stopping groove portion 284 is provided at two positions spaced a certain distance along the arc locus.

The stopping projection 282 is inserted into the corresponding stopping recessed portion 284 in accordance with the position of the large diameter portion 122 of the supporting beam 120 for the user and the position of the main shaft 150 to be described later. At this time, the stopping groove portion 284 can be positioned so as to be oriented to prevent misplacement of the mounting plate 110.

The stopping protrusion 282 is accommodated in the stopping groove 284. When the user tilts the mounting plate 110 when the stopping protrusion 282 is received in the stopping groove 284, 282 are released from the specific stopping groove portion 284 and are movable along the rim of the mounting hole portion 136 in the direction of the adjacent stopping groove portion 284.
