Abstract

A fastening system for a window shade includes a first clipping element having a first latching part, and a second clipping element having a second latching part operable to engage with the first latching part for attaching the first and second clipping element to each other, the first and second clipping element being attachable to each other for holding at least one panel of a window shade in a gap between the first and second clipping element. The first and second clipping element are attachable to each other according to a first and a second configuration, the gap between the first and second clipping element being greater in the first configuration than in the second configuration. The fastening system can hold two panels in contact with each other in the gap in the first configuration, and to hold a single panel in the gap in the second configuration.

First claim

What is claimed is:

1. A fastening system for a window shade, comprising:
a first clipping element having a first latching part, wherein the first latching part is a protruding structure that is provided at a first location on the first clipping element and has a first engagement portion and a second engagement portion; and
a second clipping element having a second latching part operable to engage with the first latching part for attaching the second clipping element to the first clipping element, wherein the second latching part is another protruding structure provided at a second location on the second clipping element, the first and second clipping element being attachable to each other for holding at least one panel of a window shade in a gap between the first and second clipping element;
wherein the first clipping element is attachable to the second clipping element according to a first configuration and a second configuration, the gap between the first clipping element and the second clipping element being greater in the first configuration than in the second configuration, the fastening system being configured to hold two panels of a window shade in contact with each other in the gap between the first clipping element and the second clipping element in the first configuration, and the fastening system being configured to hold a single panel of a window shade in the gap between the first clipping element and the second clipping element in the second configuration; and
wherein an engagement of the second latching part with the first engagement portion attaches the first clipping element to the second clipping element in the first configuration, and an engagement of the second latching part with the second engagement portion attaches the first clipping element to the second clipping element in the second configuration.

2. The fastening system according to claim 1 , wherein each of the first clipping element and the second clipping element is formed as a single piece.

3. The fastening system according to claim 1 , wherein the first latching part is fixedly connected to the first clipping element.

4. The fastening system according to claim 1 , wherein the first latching part is formed integrally with the first clipping element, and the second latching part is formed integrally with the second clipping element.

5. The fastening system according to claim 1 , wherein the first latching part including the first and second engagement portion is formed integrally with the first clipping element.

6. The fastening system according to claim 1 , wherein the first engagement portion and the second engagement portion are spaced apart from each other along a direction transversal to the gap between the first clipping element and the second clipping element.

7. The fastening system according to claim 1 , wherein each of the first and second engagement portions has a ramp surface for facilitating an engagement of the second latching part.

8. The fastening system according to claim 1 , wherein the first latching part protrudes from a first outer edge of the first clipping element, and the second latching part protrudes from a second outer edge of the second clipping element.

9. The fastening system according to claim 1 , wherein the first clipping element has a first inner surface, the second clipping element has a second inner surface, and the first clipping element is attachable to the second clipping element with the first inner surface facing the second inner surface and the gap defined between the first inner surface and the second inner surface.

10. The fastening system according to claim 9 , wherein the first clipping element has a notch open on an outer edge thereof and extending into the first inner surface, and the second clipping element has a hanger engaging portion, the notch overlapping with the hanger engaging portion when the first clipping element is attached to the second clipping element.

11. The fastening system according to claim 10 , wherein the first and second clipping element attached to each other are adapted to hold at least one panel of a window shade in a region of the gap overlapping with the notch and the hanger engaging portion.

12. The fastening system according to claim 10 , wherein one of the first inner surface and the second inner surface has a plurality of protruding teeth adapted to pierce one or more panel of a window shade, and the other one of the first inner surface and the second inner surface has a plurality of openings adapted to respectively receive at least partially the protruding teeth, the protruding teeth and the openings being distributed at two opposite sides of the notch and the hanger engaging portion.

13. The fastening system according to claim 10 , wherein the first latching part protrudes from the outer edge of the first clipping element and is adjacent to the notch.

14. A window shade comprising:
a first vertical panel, a second vertical panel and an outmost vertical panel; and
the fastening system according to claim 1 , the fastening system being disposed to either hold the first vertical panel and the second vertical panel adjacent to each other or to hold an outer side portion of the outmost vertical panel.

15. The window shade according to claim 14 , further including a head frame having a hanger provided with a slot, wherein the fastening system is connectible to the hanger with the first and second vertical panel held by the fastening system at least partially received through the slot of the hanger, or the fastening system is connectible to the hanger with the outer side portion of the outmost vertical panel held by the fastening system at least partially received through the slot of the hanger.

16. A fastening system for a window shade, comprising:
a first clipping element having a first latching part, the first latching part being a protruding structure provided at a first location on the first clipping element; and
a second clipping element having a hanger engaging portion, and a second latching part operable to engage with the first latching part for attaching the second clipping element to the first clipping element, the second latching part being another protruding structure provided at a second location on the second clipping element, the first and second clipping element being attachable to each other for holding at least one panel of a window shade in a gap between the first and second clipping element, the hanger engaging portion being configured to sideways overlap with the at least one panel when the first and second clipping element are attached to each other with the at least one panel held in the gap between the first and second clipping element.

17. The fastening system according to claim 16 , wherein the first clipping element has a notch open on an outer edge thereof, the notch overlapping with the hanger engaging portion when the first clipping element is attached to the second clipping element.

18. The fastening system according to claim 17 , wherein the first and second clipping element are adapted to hold the at least one panel with a top edge of the at least one panel positioned adjacent to the outer edge of the first clipping element.

19. The fastening system according to claim 16 , wherein the first clipping element is attachable to the second clipping element according to a first configuration and a second configuration, the gap between the first clipping element and the second clipping element being greater in the first configuration than in the second configuration,
