Bumper for portable air conditioner

1 . A bumper for a portable air conditioner, the bumper comprising:

a first outer surface and a second outer surface connected to the first outer surface;

an upper bumper and a lower bumper coupled to a lower side of the upper bumper,

wherein the upper bumper comprises:

a first upper body fixed to the first outer surface; and

a second upper body connected to the first upper body and in contact with the second outer surface,

wherein the lower bumper comprises:

a first lower body fixed to the first outer surface and coupled to a lower end of the first upper body; and

a second lower body connected to the first lower body, coupled to a lower end of the second upper body, and in contact with the second outer surface,

wherein the upper bumper further comprises:

a first upper coupling rib provided on a lower end of the first upper body; and a second upper coupling rib provided on a lower end of the second upper body;

wherein the lower bumper further comprises:

a first lower coupling rib provided on an upper end of the first lower body and coupled to the first upper coupling rib; and

a second lower coupling rib provided on an upper end of the second lower body and coupled to the second upper coupling rib;

wherein the first upper coupling rib includes a first upper interference surface facing a first direction away from the second outer surface, and the first lower coupling rib includes a first lower interference surface contacting the first upper interference surface; and

wherein the second upper coupling rib includes a second upper interference surface facing a second direction opposite to the first direction, and the second lower coupling rib includes a second lower interference surface contacting the second upper interference surface,

such that the first and second coupling ribs cooperatively engage to prevent relative sliding movement between the upper bumper and the lower bumper along the first outer surface and the second outer surface.

2 . The bumper of claim 1 , wherein the first upper coupling rib is provided with an outer interference surface parallel to the second outer surface and facing a third direction that faces the first outer surface, and

the first lower coupling rib is provided with an inner interference surface facing a fourth direction that is a direction opposite to the third direction.

3 . The bumper of claim 1 , wherein the first upper coupling rib comprises:

an upper inner rib of which an inner surface is in contact with the first outer surface;

an upper outer rib of which an inner surface is spaced apart from the first outer surface and which is connected to the second upper coupling rib; and

an upper connection rib configured to connect the upper inner rib to the upper outer rib and having one side at which the first upper interference surface is defined.

4 . The bumper of claim 3 , wherein the first upper body is provided with an upper fixing part through which a fixing member configured to fix the first upper body to the first outer surface passes and is supported,

wherein the upper fixing part is closer to the upper outer rib than the upper inner rib and provided above the upper outer rib.

5 . The bumper of claim 3 , wherein the first lower coupling rib comprises:

a lower inner rib that is in contact with an outer surface disposed at a side opposite to an inner surface of the upper inner rib; and

a lower outer rib that is in contact with an outer surface disposed at a side opposite to an inner surface of the upper outer rib,

wherein the lower inner rib has a width greater than that of the lower outer rib and is provided with the first lower interference surface on a surface connected to the inner surface of the lower outer rib.

6 . The bumper of claim 5 , wherein the first lower body is provided with a lower fixing part through which a fixing member configured to fix the first lower body to the first outer surface passes and is supported,

wherein the lower fixing part is closer to the lower outer rib than the lower inner rib and provided below the lower outer rib.

7 . The bumper of claim 3 , wherein the second upper coupling rib is connected to the upper outer rib.

8 . The bumper of claim 5 , wherein the first lower body comprises:

a first seating surface which has a height lower than that of an upper end surface of the lower inner rib to generate a stepped portion and on which the upper inner rib is seated; and

a second seating surface which has a height lower than that of an upper end surface of the lower outer rib to generate a stepped portion and on which the upper outer rib is seated, and

the second lower body is provided with a third seating surface which has a height lower than that of an upper end surface of the second lower coupling rib to generate a stepped portion and on which the second upper coupling rib is seated.
