Description

FIELD OF THE INVENTION

The present invention relates to a folding sun-shading device and particularly to a folding sun-shading device with a plurality of sun shading plates that are foldable for storing. BACKGROUND OF THE INVENTION

When vehicles are parked outdoors for a prolonged period and exposed to strong sunshine the temperature inside the vehicles increases that makes drivers entering the vehicles feel sweltering and uncomfortable. In addition, the interior seating and draperies of the vehicles also are prone to degrading, peeling or discoloring when exposed to the sunshine. To remedy such problems various types of sunshades have been developed to reduce damages caused by the strong sunshine.

A conventional vehicle sunshade includes a plurality of indented folding traces formed by compression to facilitate folding and save storing space. However, due to the folding traces are uneven, gaps are easily formed between the sunshade and vehicle window frames that result in passing through of light, or not secure coupling between them that could cause loosening off of the sunshade. To overcome those problems another type of sunshade has been developed that comprises a flexible metal frame which can be bent to fold the entire sunshade into a lump to make storing easier, and also can be extended to mate the contour of the vehicle window frames to fully block sunshine. However, the windshield of the vehicles usually is formed at a larger size, making the flexible metal frame with desired evenness requires complex fabrication processes that make manufacturing cost higher.

Moreover, fabricating the flexible metal frame for a larger area also requires greater strength and needs bigger and thicker metal frame materials, and also requires users to take greater strength and effort to bend for storing. As a result, use inconvenience increases. All this shows that there is still room for improvement.

SUMMARY OF THE INVENTION

The primary object of the present invention is to solve the problems of the conventional one-piece flexible sunshade of higher fabrication cost and not easy bending for storing.

To achieve the foregoing object the present invention provides a folding sun-shading device that comprises two sun shading plates and a bundling member. Each sun shading plate includes an ring frame, a shade curtain surrounded by the ring frame, a connecting member connecting the ring frame and the shade curtain in a spaced manner and a gap interposed between the ring frame and the shade curtain. The two ring frames include respectively one side abutting each other to be defined as a joining frame edge and other portions outside the joining frame edge defined as an operating frame edge. The bundling member binds and connects each joining frame edge through the gap, and includes a plurality of bending sections located at one side of each joining frame edge and a plurality of limitation sections located at another side from each joining frame edge and connected to each bending section. The bundling member also includes an extended state in which each bending section is tightly stretched to confine each operating frame edge to be separated from each other in a maximum manner, and a folding state in which each limitation section is tightly stretched to allow one operating frame edge to swivel and fold over another operating frame edge.

In one aspect the limitation sections are bound to each joining frame edge at a range greater than the range of the bending sections bound to each joining frame edge.

In another aspect the bending sections are plain stitching threads straddled each joining frame edge and the limitation sections are twilled stitching threads straddled each joining frame edge in a staggered manner.

In yet another aspect the bundling member includes a tail binding section at two sides of the bending sections and the limitation sections to bind each joining frame edge.

In yet another aspect the ring frame is flexible and the connecting member is a layer covered by cloth.

In yet another aspect the ring frame is flexible and the connecting member is a mesh structure.

In yet another aspect each sun shading plate includes at least one magnetic attraction member located on the ring frame.

In yet another aspect each sun shading plate includes at least one suction cup located on the shade curtain.

The invention thus formed, compared with the conventional techniques, can provide many advantages, notably:

The folding sun-shading device of the invention can be fabricated in two smaller sun shading plates that are coupled through a turning and folding structure. Through the turning and folding structure the sun shading plates can be overlapped and bent under forces to facilitate storing. Hence it can be made at a lower cost than the conventional techniques of directly making the sunshade at a greater size. Usability improves. It also can be snugly fitted to vehicle window frames to enhance light blocking efficacy.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED

EMBODIMENTS

Please referring to FIG. 1, the present invention aims to provide a folding sun-shading device 100 that mainly comprises at least two sun shading plates 10 and a bundling member 20. The folding sun-shading device 100 is deployed inside a vehicle to block sunshine from outside. The bundling member 20 is connected to each sun shading plate 10 in a bendable manner to facilitate storing of the folding sun-shading device 100. In practice the invention also can be used on other carriers such as buses, yachts or airplanes, or even windows of buildings, without limited to vehicle windows. The folding sun-shading device 100 also can include more than two sets of the sun shading plates 10.

More specifically, please referring to FIGS. 1 and 2, each sun shading plate 10 includes an ring frame 11, a shade curtain 12 surrounded by the ring frame 11, a connecting member 13 connecting the ring frame 11 and the shade curtain 12 in a spaced manner and a gap 14 interposed between the ring frame 11 and the shade curtain 12. The two ring frames 11 include respectively one side abutting each other to be defined as a joining frame edge 111 and other portions outside the joining frame edge 111 defined as an operating frame edge 112. The “joining frame edge 111” means one side of each ring frame 11 that is connected with each other, while the “operating frame edge” 112 means another side to facilitate grasping and force applying of users to make retraction for storing or folding. In this embodiment the ring frame 11 is flexible. The shade curtain 12 can be made of aluminum foiled blister cloth, mesh, yarn screen or the like. It also can be formed by coating reflective paint or the like on the shade curtain 12. The connecting member 13 is made from material with a definite stiffness such as a layer covered by cloth or a mesh structure that can be deformed under forces so that when the ring frame 11 is extended the connecting member 13 can be propped up and the shade curtain 12 also can be stretched to form a sheet with the gap 14 formed between the ring frame 11 and the shade curtain 12.

Please also referring to FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the bundling member 20 binds and connects each joining frame edge 111 through the gap 14, and includes a plurality of bending sections 21 located at one side of each joining frame edge 111 and a plurality of limitation sections 22 located at another side of each joining frame edge 111 and connected to the bending sections 21. Also referring to FIG. 5, the bundling member 20 also includes an extended state in which each bending section 21 is tightly stretched to confine each operating frame edge 112 to be separated from each other in a maximum manner, and a folding state in which each limitation section 22 is tightly stretched to allow one operating frame edge 112 to swivel and fold over another operating frame edge 112 as shown in FIGS. 6 and 7.

In a first embodiment of the invention the bending sections 21 are plain stitching threads straddled each joining frame edge 111, and the limitation sections 22 are twilled stitching threads straddled each joining frame edge 111 in a staggered manner. At the extended state because the limitation sections 22 and the bending sections 21 at two sides of the two joined sun shading plates 10 have different thread lengths, the bending sections 21 with a smaller binding range cause the strapped operating frame edge 112 unable to swivel away from the bending sections 21 because of thread length limitation. On the other hand, at the folding state, due to the limitation sections 22 have a longer thread length the two sun shading plates 10 can be swiveled and overlapped to retract the bending sections 21 into the gap 14 of the connecting member 13. In addition, the bundling member 20 further includes a tail binding section 23 at two sides of the bending sections 21 and the limitation sections 22 to bind each joining frame edge. The tail binding section 23 can be a plurality of plain stitching threads formed in a dense and continuous manner formed between the joining frame edges 111 or thread knots to avoid the threads from loosening off. However, the aforesaid structures or techniques are not the limitation of the invention.

Please referring to FIG. 8, in another embodiment of the invention each ring frame 11 includes at least one magnetic attraction element 15 located on the ring frame 11, or a suction cup 16 located on the shade curtain 12 to attach to a vehicle window frame 500 or a vehicle window or the like, so that each shade curtain 12 can securely cover the vehicle window to block sunshine as desired. The magnetic attraction element 15 or the suction cup 16 is merely one of possible embodiments. In practice they can be changed or switched according to actual requirements.

As a conclusion, the folding sun-shading device of the invention consists of the sun shading plates and the bundling member that can be made at a lower cost than the conventional flexible sun shading plate formed at a larger size.

It also makes storing easier than the conventional flexible sun shading plate of a larger size that requires greater structural strength.
