Abstract
Disclosed herein is a multipurpose opening and closing device. The device includes a casing having an opening, a manipulation unit moved up and down in the casing by a user's manipulation, an opening and closing unit operated in conjunction with the up-and-down movement of the manipulation unit to open or close the opening, and a fixing unit intended to prevent the manipulation unit from deviating from a predetermined course when the manipulation unit is moved up and down, so that a structure where the opening is opened or closed by the opening and closing unit operated in conjunction with the manipulation unit is simplified, thus reducing a failure in the device, enabling easy repair, and allowing an interior space of the casing to be efficiently used.
Claims21
A multipurpose opening and closing device, comprising:
- a casing having an opening formed therein;
- a manipulation unit moved up and down in the casing by a user's manipulation;
- and
- an opening and closing unit operated in conjunction with an up-and-down movement of the manipulation unit to open or close the opening wherein the opening and closing unit comprises:
- a moving member rotated as the manipulation unit is moved up and down;
- a connecting member connected with the moving member;
- a door connected with the connecting member to open or close the opening as the connecting member rotates,
- wherein the moving member includes an upper end rotatably coupled with the connecting member and a lower end rotatably coupled with the manipulation unit,
- wherein the connecting member includes an upper end rotatably coupled with the door, a lower end rotatably coupled with the upper end of the moving member, and a rotating axis protrusion movably coupled with the casing, and
- wherein the connecting member is aligned with the moving member to be rotated in a direction opposite to a rotating direction of the moving member.
A multipurpose opening and closing device, comprising:
- a casing having an opening formed therein;
- a manipulation unit moved up and down in the casing by a user's manipulation;
- and
- an opening and closing unit operated in conjunction with an up-and-down movement of the manipulation unit to open or close the opening, wherein the opening and closing unit comprises:
- a moving member having an upper end and a lower end, the lower end of the moving member being connected to the manipulation unit;
- a connecting member having an upper end and a lower end, the lower end of the connecting member rotatably coupled with the upper end of the moving member;
- a door rotatably coupled with the upper end of the connecting member to open or close the opening as the connecting member rotates,
- wherein when the user's manipulation moves the manipulation unit up, the moving member rotates in a first direction, the connecting member rotates in a second direction, and the door opens.
