Abstract

A handle extension structure includes a connection assembly and an operation assembly. The connection assembly has a first end and a second end opposite to each other. The operation assembly is slidably disposed at the connection assembly. The operation assembly includes an extension element and a grip element. The extension element has a first end portion and a second end portion opposite to each other. The first end portion is slidably disposed between the first end and the second end. The grip element is pivoted to the second end portion. An electronic device casing includes a body, a movable apparatus, and the handle extension structure. The handle extension structure is pivoted to the movable apparatus through the connection assembly.

First claim

What is claimed is:

1. A handle extension structure, comprising:
a connection assembly, comprising a first end and a second end opposite to each other; and
an operation assembly, slidably disposed at the connection assembly and comprising:
an extension element, comprising a first end portion and a second end portion opposite to each other, the first end portion being slidably disposed between the first end and the second end; and
a grip element, pivoted to the second end portion,

wherein when the first end portion of the extension element is located at the first end, a portion of the grip element is located in the connection assembly, a total length of the connection assembly and the operation assembly is a first length, and the second end portion is located between the first end and the second end, and
when the first end portion slides to the second end to locate the grip element outside the connection assembly, the total length of the connection assembly and the operation assembly is a second length, the second end portion moves out of the second end, and the grip element is adapted to rotate relative to the second end portion, the second length being greater than the first length.

2. The handle extension structure according to claim 1 , wherein the connection assembly comprises a body portion, at least one first slot arm, at least one second slot arm, and at least one positioning portion, the body portion comprises the first end and the second end opposite to each other, the first slot arm extends from the first end to the second end, the second slot arm extends from the second end to the first end, a sliding slot is defined among the body portion, the first slot arm and the second slot arm, the first slot arm and the second slot arm are opposite to each other and are separated by a gap, the gap communicates with the sliding slot, and the positioning portion is connected to one of the first slot arm and the second slot arm and is located beside the gap,
wherein the extension element further comprises at least one sliding block, the at least one sliding block protrudes from the first end portion and is slidably disposed at the sliding slot, and the positioning portion is adapted to abut against the sliding block to position the operation assembly relative to the connection assembly.

3. The handle extension structure according to claim 1 , wherein a first inner diameter of the connection assembly is equal to a first outer diameter of the first end portion of the extension element, and a second outer diameter of the grip element is equal to a first outer diameter of the connection assembly.

4. The handle extension structure according to claim 3 , wherein a third outer diameter of the second end portion of the extension element is equal to a second inner diameter of the grip element.

5. The handle extension structure according to claim 3 , wherein the operation assembly further comprises a protrusion element, and the protrusion element is located at an end of the grip element opposite to a location where the grip element is pivoted to the second end portion, a fourth outer diameter of the protrusion element being greater than the second outer diameter of the grip element.

6. The handle extension structure according to claim 1 , further comprising:
a positioning structure, configured to change a position of the grip element relative to the connection assembly.

7. The handle extension structure according to claim 6 , wherein the positioning structure comprises:
at least one positioning block, disposed at the grip element; and
at least one positioning slot, disposed at the connection assembly, and adapted to receive the positioning block to change the position of the grip element relative to the connection assembly.

8. The handle extension structure according to claim 6 , wherein the positioning structure comprises:
at least one guide arc portion, disposed at the second end portion of the extension element; and
at least one pressing element, disposed at the grip element and movably penetrating the guide arc portion, so that the grip element is selectively adapted to rotate relative to the second end portion.

9. The handle extension structure according to claim 8 , wherein the pressing element is slidably disposed at the grip element, and the positioning structure further comprises:
at least one restoring member, abutting between the pressing element and the grip element;
an escape space, defined in the second end portion of the extension element, and communicating with the guide arc portion;
at least one first recessed portion, disposed at the second end portion, connected to the escape space and the guide arc portion, and extending from the guide arc portion to a location where the grip element and the second end portion of the extension element are pivoted;
at least one second recessed portion, disposed at the second end portion, connected to the escape space and the guide arc portion, and extending from the guide arc portion to the location where the grip element and the second end portion of the extension element are pivoted, the first recessed portion and the second recessed portion being perpendicular to each other;
at least one stop portion, defined between the first recessed portion and the second recessed portion, and adjacent to the guide arc portion; and
at least one locking portion, disposed at the pressing element, extending toward the location where the grip element and the second end portion of the extension element are pivoted, and adapted to move with the pressing element;
wherein when the locking portion is locked to one of the first recessed portion and the second recessed portion, the stop portion is located on a moving path of the locking portion and stops the locking portion to change the position of the grip element relative to the connection assembly, and when a force is applied to the pressing element to deform the restoring member, the locking portion moves into the escape space from the one of the first recessed portion and the second recessed portion, and the stop portion moves out of the moving path of the locking portion, so that the grip element is adapted to rotate relative to the extension element.

10. An electronic device casing, comprising:
a body;
a movable apparatus, adapted to be assembled on the body; and
a handle extension structure, comprising:
a connection assembly, comprising a first end and a second end opposite to each other, and adapted to be pivoted on the movable apparatus; and
an operation assembly, slidably disposed at the connection assembly, the operation assembly comprising:
an extension element, comprising a first end portion and a second end portion opposite to each other, the first end portion being slidably disposed between the first end and the second end; and
a grip element, pivoted to the second end portion;

wherein when the first end portion of the extension element is located at the first end, a portion of the grip element is located in the connection assembly, a total length of the connection assembly and the operation assembly is a first length, and the second end portion is located between the first end and the second end; and
when the first end portion slides to the second end to locate the grip element outside the connection assembly, the total length of the connection assembly and the operation assembly is a second length, the second end portion moves out of the second end, and the grip element is adapted to rotate relative to the second end portion, the second length being greater than the first length.

11. The electronic device casing according to claim 10 , wherein the connection assembly comprises
