2. The cup holder for the vehicle of claim 1,
wherein a front portion of the supporting portion protrudes as a curved surface.
3. The cup holder for the vehicle of claim 1,
wherein an upper end of the supporting portion is rotatably secured to an upper end of the inner hole such that the supporting portion can not be separated from the inner hole.
4. The cup holder for the vehicle of claim 2,
wherein an inner portion of the supporting portion has an empty space such that the compression springs can be at least partially inserted therein.
5. The cup holder for the vehicle of claim 1, wherein
a front portion and a rear portion of the compression springs are respectively connected to an inner surface of the supporting portion and a fixing portion formed in the inner hole of the main body of the cup holder.
6. A beverage container holder comprising:
a housing body defining an insertion hole for receiving a beverage container;
a container support mounted to the body and rotatable in two vertical directions about a horizontal axis, the support protruding at least partially into the insertion hole for contacting a container and being at least partially retractable from the insertion hole; and
a biasing member biasing the support towards the insertion hole;
wherein the support is rotatable in the two vertical directions in response to inserting and removing a container from the insertion hole.
7. The beverage container of claim 6, wherein the container support is also axially movable in a horizontal direction with respect to the insertion hole.
8. The beverage container of claim 6, further comprising a pin rotatably connecting the support to the body, the pin defining the horizontal axis.
9. The beverage container of claim 8, further comprising the pin being received in a horizontal groove disposed in the body, the pin axially movable in the horizontal groove in at least one lateral direction with respect to the insertion hole.
10. The beverage container of claim 6, wherein the biasing member further comprises two helical compression springs.
11. The beverage container of claim 10, wherein one spring each is disposed above and below the horizontal axis.
12. The beverage container of claim 6, wherein the support includes a front portion with curved surface facing towards the insertion hole.
13. The beverage container of claim 6, wherein the first vertical rotatable direction is downwards and the second vertical rotatable direction is upwards.
14. The beverage container of claim 6, wherein the body further defines an inner hole adjacent the insertion hole, the container support being at least partially retractable into the inner hole.
15. The beverage container of claim 14, wherein the container support is fully retractable into the inner hole.
16. The beverage container of claim 6, further comprising the support being rotatable in the two vertical directions with the support partially retracted from the insertion hole.
17. The beverage container of claim 9, further comprising an upper end of container support being pivotally mounted to the housing body.
18. The beverage container of claim 17, further comprising the upper end having a pin received in a groove disposed in the housing body at an angle to the horizontal groove.
19. A beverage container holder for a vehicle comprising:
a body defining an insertion hole for receiving a beverage container and an adjacent inner hole open to the insertion hole, the body further defining two spaced-apart horizontal grooves;
a container supporting member rotatably mounted to the body and having a wedge-shaped front portion for abutting a beverage container, the supporting member protruding at least partially into the insertion hole for contacting a container and being at least partially retractable from the insertion hole into the inner hole;
at least one pin received in the horizontal grooves of the body and rotatably connecting the supporting member to the body, the pin defining a rotational axis for the supporting member; and
two biasing members biasing the support towards the insertion hole,
wherein in response to inserting and removing a beverage container from the insertion hole, the supporting member is rotatably movable upwards and downwards about the rotational axis and is further movable in an axial horizontal direction with respect to the insertion hole.
20. The beverage container holder of claim 19, further comprising an upper end of container support being pivotally mounted to the housing body, the upper end having a pin received in a groove disposed in the housing body at an angle to the horizontal groove.
The claims below are in addition to those above.
