Abstract: Disclosed is a helmet. The helmet according to an aspect of the present disclosure may comprise: a helmet body provided to surround a user's head; a fixed member fixed on a side surface of the helmet body and provided with a mounting portion; a moving member which is coupled to the fixed member so as to be able to move back and forth in a straight line, and includes a pass-through portion at a position corresponding to the mounting portion; and a pivot member which is provided with a cam and pivots according to pivoting of the cam, wherein the cam passes through the pass-through portion and is pivotably disposed on the mounting portion.

Abstract: A helmet is disclosed. A helmet according to an exemplary embodiment of the present invention may include: a helmet body capable of surrounding a user's head; a fixing member which is fixed to a side surface of the helmet body and has a cam seat part; a movable member coupled to the fixing member so as to be linearly movable forward or backward; a pivot member which has a cam pivotally seated on the cam seat part and is disposed to be engaged with the movable member so as to be pivotable around the cam as a pivot axis; and a pressing member disposed in the fixing member to elastically support the cam and press the cam backward, wherein when the pivot member pivots from a first position toward a second position, the pivot axis moves forward and the pivot member and the movable member are accordingly displaced forward.

Abstract: A mobile terminal comprises: a frame having a changing shape or size; a flexible display unit having one side facing outwards, and comprising a fixed portion coupled to the frame and a variable portion bent in a first direction; and a support frame located on the other side of the variable portion of the flexible display unit, wherein the support frame comprises: a plurality of rigid bars extending in a second direction perpendicular to the first direction and arranged side by side in the first direction; and a flexible portion for combining the rigid bars, wherein the support frame bends well in response to the flexural deformation of the flexible display unit and at the same time stably supports the other side of the variable portion, so that the flexible display unit may be stably deformed according to the deformation of the mobile terminal.

Abstract: A rollable mobile terminal comprises: a rolling part bent in a first direction and comprising a flexible display unit and a flexible frame which is bent and located on the rear surface of the flexible display unit; a first body having a cylindrical accommodation part in which one side of the rolling part in the first direction is rolled and stored, and an opening formed in one side thereof through which the rolling part enters and is withdrawn; and a second body to which the other side of the rolling part in the first direction is coupled, wherein the rollable mobile terminal can be changed into a state in which the rolling part is accommodated in the first body, and the first body and the second body are closed, or a state in which the rolling part is withdrawn to the outside and the first body and the second body are separated from each other and open, and, even when the flexible display unit is unrolled, the flexible display unit is stably supported such that a display device is supported and a touch input
