## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority of Taiwanese Patent Application No. 101210824, filed on Jun. 5, 2012.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a sunshade assembly, more particularly to a sunshade assembly adapted for use with a vehicle.
2. Description of the Related Art
In order to avoid direct sunlight from penetrating through a vehicle window and affecting the comfort of a passenger, the vehicle generally has a window tint adhered to the vehicle window, and might additionally have a sunshade installed that covers the vehicle window and blocks the sunlight, thereby enhancing the shading effect.
Referring to FIGS. 1 and 2, a conventional sunshade 1 is mounted near a vehicle window 10, and includes a mounting seat 11, a reeling shaft 12 that is rotatably mounted to the mounting seat 11 and that extends in an extending direction, a foldable shade member 13 that is connected to the reeling shaft 12 and that has an expandable end section 131 extending in the extending direction and spaced apart from the reeling shaft 12, a sidebar 14 that is mounted to the expandable end section 131, and two end components 15 that are coupled respectively to opposite ends of the sidebar 14 in the extending direction.
When in use, the sidebar 14 is moved to unfold the shade member 13 for covering the vehicle window 10. However, since the end components 15 are only configured to be coupled to the sidebar 14 and are unable to be mounted with the shade member 13, the expandable end section 131 is mounted only on the sidebar 14, i.e., the length of the expandable end section 131 in the extending direction is equal to that of the sidebar 14. As a result, with the provision of the end components 15, a gap (D) will be formed between each of opposite sides 132 of the shade member 13 in the extending direction and a corresponding one of opposite sides of the vehicle window 10 allowing for passage of sunlight, thereby providing poor shading effect.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a sunshade assembly that can provide effective shading for a vehicle window.
According to the present invention, there is provided a sunshade assembly including amounting seat, a reeling shaft, a foldable shade member, a sidebar, and two end components. The reeling shaft extends in an extending direction and is rotatably mounted to the mounting seat. The foldable shade member is connected to the reeling shaft, and has an expandable end section extending in the extending direction and spaced apart from the reeling shaft in a first transverse direction that is transverse to the extending direction. The expandable end section has two side portions that are spaced apart from each other in the extending direction, and a center portion that interconnects the side portions. The sidebar extends along the extending direction, and is provided with a first receiving groove that extends through opposite ends of the sidebar in the extending direction and that is engaged with the center portion of the expandable end section of the shade member. The two end components are connected respectively to the opposite ends of the sidebar. Each of the end components is provided with a second receiving groove that is in spatial communication with the first receiving groove and that is engaged with a respective one of the side portions of the expandable end section of the shade member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 3 to 5, the preferred embodiment of a sunshade assembly according to the present invention is adapted to be mounted in a vehicle (not shown) to cover a vehicle window 2. The vehicle window 2 is a rear windshield in this embodiment, and may be a sunroof or a side window; therefore, the positioning of the sunshade assembly is not limited to this embodiment. The sunshade assembly includes a mounting seat 3, a reeling shaft 4, a shade member 5, a sidebar 6, two end components 7 and two locking members 8.
The mounting seat 3 is a hollow body mounted under the vehicle window 2. The configuration of the mounting seat 3 may vary in other embodiments of the present invention.
The reeling shaft 4 extends in an extending direction (X) and is rotatably mounted to the mounting seat 3.
The foldable shade member 5 is connected to the reeling shaft 4 and has an expandable end section 52, a main section 53, and an insertion rod 54.
The expandable end section 52 extends in the extending direction (X) and is spaced apart from the reeling shaft 4 in a first transverse direction (Y) that is transverse to the extending direction (X). The expandable end section 52 has two side portions 521 that are spaced apart from each other in the extending direction (X), and a center portion 522 that interconnects the side portions 521. The main section 53 interconnects the end section 52 and the reeling shaft 4. In this embodiment, the expandable end section 52 is folded to form a sleeve, such that the main section 53 has a thickness in a second transverse direction (Z) transverse to the extending direction (X) and the first transverse direction (Y) which is smaller than that of the expandable end section 52. The insertion rod 54 is sleeved in the expandable end section 52 of the shade member 5 and is used for supporting the main section 53. The sunshade assembly further includes a torsion spring (not shown) for biasing the reeling shaft 4 to rotate for retracting the shade member 5.
The sidebar 6 extends along the extending direction (X), and is formed with a main groove 61 and a first receiving groove 62 spaced apart from the main groove 61. The main groove 61 extends through opposite ends of the sidebar 6 in the extending direction (X). The first receiving groove 62 extends through the opposite ends of the sidebar 6 in the extending direction (X), and is engaged with the center portion 522 of the expandable end section 52 of the shade member 5. The first receiving groove 62 has a first opening 621 for extension of the center portion 522 of the expandable end section 52.
The end components 7 are connected respectively to the opposite ends of the sidebar 6. Each of the end components 7 has an end segment 71 that abuts against a respective one of the opposite ends of the sidebar 6, and an insertion segment 72 that projects from the end segment 71 and that is inserted into the main groove 61. Each of the end components 7 is formed with a second receiving groove 73 that is in spatial communication with the first receiving groove 62, and that is engaged with a respective one of the side portions 521 of the expandable end section 52 of the shade member 5. The second receiving groove 73 of each of the end components 7 is disposed in the end segment 71 of the end component 7, and has a second opening 731 for extension of the respective one of the side portions 521 of the expandable end section 52.
The locking members 8 respectively secure the end components 7 with the sidebar 6. Each locking member 8 is a screw and is screwed into the sidebar 6 and the insert segment 72 of a respective one of the end components 7. The configuration of the locking members 8 may vary, and the quantity of the locking members 8 may increase to enhance the connection strength between the end components 7 and the sidebar 6.
The sunshade assembly further includes a drive unit 9 mounted to the mounting seat 3 and driving the sidebar 6 into motion. In this embodiment, the drive unit 9 is electrically controlled for unfolding and folding the shade member 5 via the movement of the sidebar 6. The design of the drive unit 9 may, in other embodiments be manual, semi-automatic and so forth. In addition, the sunshade assembly may further include two guide rails (not shown) engaging respectively the end segments 71 of the end components 7 for guiding movement of the end components 7 during the folding and unfolding of the shade member 5.
Referring to FIGS. 3, 4 and 6, when in use, the drive unit 9 may be activated to move the sidebar 6 with respect to the mounting seat 3 to an expanded position distal to the reeling shaft 4 for expanding the shade member 5 to cover the vehicle window 2 and block the sunlight. The provision of the second receiving grooves 73 of the end components 7 that respectively engage with the side portions 521 of the shade member 5 allows a relatively wide shade member 5 to be coupled to the sidebar 6 and the end components 7 with lateral edges 51 of the shade member 5 being close to opposite sides 21 of the vehicle window 2 in the extending direction (X). Accordingly, a gap (d) formed between each of the opposite sides 21 of the vehicle window 2 and the respective side 51 of the shade member 5 is shorter than the gap (D) mentioned in the prior art, thereby increasing the area of coverage and enhancing the shading effect.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
