Abstract

This application relates to a hook assembly for a door curtain of a vehicle. The hook assembly is installed on a door panel to which a door curtain is hooked and fixed. The hook assembly includes a hook body installed to pass through a through-hole formed in the door panel in a load direction due to the door curtain, and a hook pin engaged with the hook body in a direction perpendicular to the load direction due to the door curtain. When the hook pin is engaged with the hook body, the hook body is supported in the through-hole in an engaged direction of the hook pin and one side of the hook body is pressed against a circumference of the through-hole.

First claim

What is claimed is:

1. A hook assembly for a door curtain of a vehicle, the hook assembly is to be installed on a door panel and hooked and fixed to the door curtain, the hook assembly comprising:
a hook body to be installed to pass through a through-hole formed in the door panel in a load direction in which the door curtain is applied; and
a hook pin to engage the hook body in an engagement direction that is perpendicular to the load direction,
wherein, when the hook pin is engaged with the hook body, one side of the hook body is pressed against a circumference of the through-hole while supporting the hook body in the through-hole in the engagement direction.

2. The hook assembly of claim 1 , wherein the hook body includes:
a base to come into contact with a bottom surface of the door panel;
an extension part formed upward from the base to come into contact with an inner circumference of the through-hole when the engagement of the hook pin is completed;
an engagement part on an upper portion of the extension part, wherein a lower circumference of the engagement part is hooked to the circumference of the through-hole when the engagement of the hook pin is completed to prevent the hook body from being separated from the door panel; and
an elastic part extending from the extension part in a direction opposite the engagement direction, wherein the elastic part includes a rear end to support the hook body in the engagement direction.

3. The hook assembly of claim 2 , wherein:
the engagement part has a width that tapers in the engagement direction, and
the extension part has a side surface to come into contact with a side contact surface of the through-hole.

4. The hook assembly of claim 2 , wherein an outer surface of the extension part is inclined at a predetermined angle with respect to the engagement direction.

5. The hook assembly of claim 2 , wherein the rear end of the elastic part includes an elastic support to come into contact with a rear contact surface of the through-hole when the engagement of the hook pin with the hook body is completed.

6. The hook assembly of claim 5 , wherein the elastic support is an inclined surface to support the hook body to be moved toward a front contact surface of the through-hole at a front end of the extension part.

7. The hook assembly of claim 5 , wherein, until an outer surface of the extension part comes into contact with a side contact surface formed on a side surface of the through-hole, the elastic support elastically supports the hook body to allow the front end of the extension part to be moved toward a front contact surface of the through-hole.

8. The hook assembly of claim 2 , wherein the hook pin includes:
a press part to engage the hook pin with the hook body;
a slider extending from the press part in the engagement direction and inserted into a hook pin accommodation groove in the hook body; and
a fixing support extending for a predetermined length from a front end of the slider toward the press part to support a bottom surface of the elastic part when the hook pin is engaged with the hook body.

9. The hook assembly of claim 8 , wherein the elastic part includes a fixing bump on the bottom surface of the elastic part to prevent the hook pin from being moved rearward so as to prevent the hook pin from being separated when the hook pin is engaged with the hook body.

10. The hook assembly of claim 9 , wherein the slider includes a stopper on a front end of the slider to be hooked and fixed to the hook pin when the hook pin is engaged with the hook body.

11. The hook assembly of claim 10 , wherein the fixing bump includes:
an inclined surface to allow the stopper to pass therethrough when the hook pin is engaged with the hook body; and
a stop surface to prevent a rearward movement of the hook pin after the hook pin is engaged with the hook body.

12. The hook assembly of claim 8 , wherein:
the fixing support includes a support block on a rear end of the fixing support to support the bottom surface of the elastic part when the engagement of the hook pin with the hook body is completed;
the hook body includes a support block accommodation groove on an inner surface of the base to accommodate the support block; and
the support block is accommodated in the support block accommodation groove until the engagement of the hook pin with the hook body is completed, and when the engagement of the hook pin with the hook body is completed, the support block is separated from the support block accommodation groove to support the bottom surface of the elastic part.

13. The hook assembly of claim 12 , wherein, when the engagement of the hook pin with the hook body is completed, a bottom surface of the support block is supported on a bottom surface of the hook pin accommodation groove.

14. The hook assembly of claim 8 , wherein the hook pin accommodation groove includes a hook pin support groove at an entrance of the hook pin accommodation groove to support the bottom surface of the hook pin.

15. The hook assembly of claim 2 , wherein:
a width of the extension part is smaller than a width of the engagement part;
the engagement part has the same width as the through-hole; and
after the engagement part is inserted upward from a lower portion of the through-hole, the engagement part is moved toward the hook pin in the width direction of the vehicle, and the bottom surface of the engagement part is hooked and fixed to the through-hole.

16. The hook assembly of claim 8 , wherein:
the hook pin includes catching hooks protruding from both sides of the slider in a direction perpendicular to the engagement direction;
the hook pin accommodation groove includes a catching bump on an inner surface of the hook pin accommodation groove to engage the catching hooks; and
when the engagement of the hook pin with the hook body is completed, the catching hooks and the catching bump engage each other.

17. The hook assembly of claim 2 , further comprising:
a connector extending downward from one end of the base; and
a curtain fixing part which extends from a lower end of the connector to hook and fix an upper end of the door curtain.
