Abstract

An electronic device includes: a housing including a pin; and a strap detachably coupled to the housing. The strap includes: a coupling groove that includes a first end that surrounds the pin and a second end that is open toward a first surface of the strap; and a button including an inclined surface that is inclined with respect to the first surface of the strap and slidable relative to the pin. A first portion of the button is movable into or out of the coupling groove, wherein a gap between the first portion of the button and an inner surface of the coupling groove is expanded as the button moves in a first direction toward a second surface of the strap opposite to the first surface of the strap, and wherein the gap is reduced as the button moves in a second direction opposite to the first direction.

First claim

What is claimed is:

1 . An electronic device comprising:
a housing comprising a pin; and a strap detachably coupled to the housing, wherein the strap comprises:
a coupling groove that comprises a first end that surrounds the pin in a state in which the strap is coupled to the housing, and a second end that is open toward a first surface of the strap in the state in which the strap is coupled to the housing; and
a button comprising an inclined surface that is inclined with respect to the first surface of the strap and that is slidable relative to the pin, in the state in which the strap is coupled to the housing,
wherein a first portion of the button is movable into or out of the coupling groove, wherein a gap between the first portion of the button and an inner surface of the coupling groove is expanded as the button moves in a first direction toward a second surface of the strap opposite to the first surface of the strap, and wherein the gap is reduced as the button moves in a second direction opposite to the first direction.

2 . The electronic device of claim 1 , wherein, in the state in which the strap is coupled to the housing, a distance between a first point of the pin corresponding to a position of an end of the inclined surface and a second point on an outer surface of the pin, the second point being spaced apart from the first point in the first direction, is 70% or more of a diameter of the pin.

3 . The electronic device of claim 2 , wherein the distance between the first point and the second point decreases as the button moves in the first direction, and
wherein the distance between the first point and the second point increases as the button moves in the second direction.

4 . The electronic device of claim 1 , wherein the strap further comprises an elastic member that is configured to press the button in the second direction when compressed by the button.

5 . The electronic device of claim 4 , wherein the button further comprises a coupling protrusion extending in the first direction and surrounded by the elastic member.

6 . The electronic device of claim 1 , wherein a portion of the coupling groove is parallel to the inclined surface.

7 . The electronic device of claim 1 , wherein the strap further comprises:
a receiving portion surrounding the button and corresponding to the coupling groove; and a supporting portion surrounding the receiving portion, the supporting portion comprising a first material that is different from a second material of the receiving portion.

8 . The electronic device of claim 7 , wherein the receiving portion further comprises a through hole that penetrates the receiving portion and that is connected to the coupling groove,
wherein the strap further comprises a plug that is inside the through hole, and wherein the plug comprises a third material that is different from the second material of the receiving portion.

9 . The electronic device of claim 1 , wherein the strap further comprises a fixing groove on an inner surface of the strap, the inner surface of the strap being perpendicular to the first surface of the strap,
wherein the button further comprises a fixing protrusion on a side surface of the button, the side surface facing the inner surface of the strap, and wherein the fixing protrusion is coupled within the fixing groove.

10 . The electronic device of claim 1 , wherein a state of the button corresponds to either of:
a first state in which a second portion of the button protrudes from the first surface of the strap; or a second state in which the second portion of the button is disposed inside the strap.

11 . The electronic device of claim 10 , wherein the first portion of the button is:
disposed inside the coupling groove when the state of the button is the first state; and disposed outside the coupling groove when the state of the button is the second state.

12 . The electronic device of claim 1 , wherein the button further comprises:
a first connection surface that is connected to a first end of the inclined surface, faces the pin, and is parallel to the first direction; and a second connecting surface that is connected to a second end of the inclined surface and is parallel to the first direction.

13 . The electronic device of claim 1 , wherein the first surface of the strap is bent with a curvature.

14 . The electronic device of claim 1 , wherein the strap is configured to be rotatable with respect to the housing in the state in which the strap is coupled to the housing.

15 . The electronic device of claim 1 , wherein the strap comprises an elastically deformable material configured to be deformable by an external force.

16 . An electronic device comprising:
a housing comprising:
a first surface facing a portion of a body of a user in a state in which the electronic device is worn by the user,
a side surface surrounding the first surface,
a protruding portion extending from the side surface, and
a pin extending through the protruding portion; and
a strap that is detachably coupled to the housing, wherein the strap comprises:
a first surface that surrounds a portion of the body of the user in the state in which the electronic device is worn by the user, and
a coupling groove comprising a first end that surrounds the pin in a state in which the strap is coupled to the housing, and a second end that is open toward the first surface of the strap in the state in which the strap is coupled to the housing;
a button comprising an inclined surface that is inclined with respect to the first surface of the strap and is slidable relative to the pin, in the state in which the strap is coupled to the housing the strap is coupled to the housing, wherein a first portion of the button is movable into or out of the coupling groove; and
an elastic member that is coupled to a second portion of the button and is deformable by a movement of the button,
wherein a gap between the first portion of the button and an inner surface of the coupling groove is expanded as the button moves in a first direction toward a second surface of the strap opposite to the first surface of the strap, and wherein the gap between the first portion of the button and the inner surface of the coupling groove is reduced as the button moves in a second direction opposite to the first direction.

17 . The electronic device of claim 16 , wherein, in the state where the strap is coupled to the housing, a distance between a first point of the pin, the first point corresponding to a location of an end of the inclined surface, and a second point on an outer surface of the pin, the second point being spaced apart from the first point in the first direction, is 70% or more of a diameter of the pin.

18 . The electronic device of claim 16 , wherein the button further comprises a coupling protrusion extending in the first direction and surrounded by the elastic member.

19 . The electronic device of claim 16 , wherein a portion of the coupling groove is parallel to the inclined surface.

20 . The electronic device of claim 16 , wherein the strap further comprises a fixing groove on an inner surface of the strap, the inner surface being perpendicular to the first surface of the strap, and
wherein the button further comprises a fixing protrusion that is on a side surface of the button facing the inner surface of the strap, and is coupled within the fixing groove.
