Abstract

The present disclosure provides a connector, comprising an installation surface, a first reclined surface and a second reclined surface respectively located on two sides of the installation surface, and a connection surface opposite to the installation surface; the first reclined surface and the second reclined surface extend from the installation surface to the connection surface, and the distance between the first reclined surface and the second reclined surface gradually increases from the installation surface to the connection surface. The present invention also discloses a connection assembly and a sofa. The present invention makes the connection convenient, the assembly simple, and the production cost low.

First claim

What is claimed is:

1. A connecting wedge assembly, comprising:
at least three connecting wedges, wherein each of the at least three connecting wedges comprises:
an installation surface;
a first reclined surface;
a second reclined surface, wherein the first reclined surface and the second reclined surface are located on opposite sides of the installation surface; and
a connection surface opposite to the installation surface;
wherein the first and second reclined surfaces extend from the installation surface to the connection surface such that a distance between the first and second reclined surfaces increases gradually along a direction from the installation surface to the connection surface,
wherein at least a first connecting wedge and a second connecting wedge of the at least three connecting wedges are configured to be secured side by side to a first support member, thereby forming a slot between the first connecting wedge and the second connecting wedge, and
wherein a third connecting wedge of the at least three connecting wedges is configured to be secured to a second support member and slide into the slot formed between the first connecting wedge and the second connecting wedge, and thereby connect the first support member and the second support member together.

2. The connecting wedge assembly of claim 1 , wherein the slot is formed between the first reclined surface of the first connecting wedge and the second reclined surface of the second connecting wedge, with a slot shape that is narrower on an outer side and wider on an inner side of the slot.

3. The connecting wedge assembly of claim 1 , wherein the each of the at least three connecting wedges further comprises a first curved surface, wherein the first curved surface connects to a first group of ends of the installation surface, the connection surface, the first and second reclined surfaces, wherein the first curved surface extends from the installation surface to the connection surface such that a distance between the first curved surface and a center of the each of the at least three connecting wedges increases gradually along a direction from the installation surface to the connection surface.

4. The connecting wedge assembly of claim 3 , wherein a guiding path is formed between the curved surfaces of a first connecting wedge and a second connecting wedge, with a guiding path shape that is wider on a receiving side and narrower on an inserted side of the guiding path.

5. The connecting wedge assembly of claim 3 , wherein a guiding path is formed between the curved surfaces of a first connecting wedge and a second connecting wedge, wherein the guiding path is in a funnel shape.

6. The connecting wedge assembly of claim 3 , wherein the each of the at least three connecting wedges further comprises a second curved surface, wherein the second curved surface connects to a second group of ends of the installation surface, the connection surface, the first and second reclined surfaces.

7. The connecting wedge assembly of claim 1 , wherein the first and second reclined surfaces are in axial symmetry with each other.

8. The connecting wedge assembly of claim 1 , wherein the each of the at least three connecting wedges further comprises an installation hole.

9. The connecting wedge assembly of claim 1 , wherein the each of the at least three connecting wedges is in a long strip shape.

10. The connecting wedge assembly of claim 9 , wherein a length of the each of the at least three connecting wedges is longer than a width of the each of the at least three connecting wedges.

11. The connecting wedge assembly of claim 10 , wherein a first connecting wedge and a second connecting wedge of the at least three connecting wedges are configured to be secured in parallel to each other along the longer side of the wedges.

12. The connecting wedge assembly of claim 1 , wherein the each of the at least three connecting wedges further comprises a protruding portion.

13. The connecting wedge assembly of claim 1 , wherein the at least three connecting wedges are identical.

14. A sofa, comprising:
one or more sofa components, wherein the one or more sofa components are connected by at least three connecting wedges, wherein each of the at least three connecting wedges comprises:
an installation surface;
a first reclined surface;
a second reclined surface, wherein the first reclined surface and the second reclined surface are located on opposite sides of the installation surface;
a connection surface opposite to the installation surface;
wherein the first and second reclined surfaces extend from the installation surface to the connection surface such that a distance between the first and second reclined surfaces increases gradually along a direction from the installation surface to the connection surface,
wherein at least a first connecting wedge and a second connecting wedge of the at least three connecting wedges are configured to be secured side by side to a first support member, thereby forming a slot between the first connecting wedge and the second connecting wedge, and
wherein a third connecting wedge of the at least three connecting wedges is configured to be secured to a second support member and slide into the slot formed between the first connecting wedge and the second connecting wedge, and thereby connect the first support member and the second support member together.

15. The sofa of claim 14 , wherein the one or more sofa components comprise two or more frames, wherein the two or more frames are configured to be connected to one another by three or more of the connecting wedges.

16. The sofa of claim 14 , wherein the each of the at least three connecting wedges further comprises a curved surface, wherein the curved surface connects to a first group of ends of the installation surface, the connection surface, the first and second reclined surfaces, wherein the curved surface extends from the installation surface to the connection surface such that a distance between the curved surface and a center of the each of the at least three connecting wedges increases gradually along a direction from the installation surface to the connection surface.

17. The connecting wedge assembly of claim 1 , wherein the each of the at least three connecting wedges further comprises an installation hole.

18. The sofa of claim 14 , wherein the one or more sofa components comprise a frame and an armrest, wherein the frame and the armrest are configured to be connected by three or more of the connecting wedges.

19. The sofa of claim 14 , wherein the one or more sofa components comprise a frame and a backrest, wherein the frame and the backrest are configured to be connected by three or more of the connecting wedges.
