Description

Technical Field

[0001] This utility model relates to the technical field of umbrellas, and more particularly to a folding umbrella with stable creases. Background Technology

[0002] Umbrellas, as tools for rain protection and sunshade, are essential daily necessities in our lives. Among them, folding umbrellas have the advantages of small storage volume, convenient carrying, and easy to keep the umbrella surface clean.

[0003] Chinese Patent Publication No. CN221044424U discloses an easy-to-fold umbrella. The specific content is as follows: An easy-to-fold umbrella includes an umbrella fabric, an umbrella handle, and a foldable frame. The foldable frame is installed on the umbrella handle. The umbrella fabric is fixedly covered on the outer surface of the foldable frame and can be folded together with the foldable frame. At least one torsional elastic element is fixedly installed on each support frame of the foldable frame or on the fold line extending radially along the umbrella fabric between two adjacent support frames. The two ends of the torsional elastic element for torque output are respectively fixed with rigid support plates that can elastically deform along the circumference of the umbrella handle under external force. Each rigid support plate is fixedly connected to the umbrella fabric, and each rigid support plate is located between fold lines spaced apart along the circumference of the umbrella fabric. When the foldable frame is in the folded state, the torsional elastic element drives the umbrella fabric to automatically fold along the fold lines through the rigid support plates.

[0004] While the aforementioned patent achieves a straight and regular folded state of the umbrella fabric when closed using a rigid support plate, the increased weight of the umbrella is due to the correlation between the hardness and density of the material, making it inconvenient to carry for extended periods. Furthermore, when the umbrella fabric is rolled up for a long time, the edge of the rigid support plate continuously squeezes the fabric, causing severe wear and tear on the fabric in that area, resulting in low durability of the umbrella fabric.

[0005] In view of this, the inventor has designed a folding umbrella with stable creases, and this invention is thus derived. Utility Model Content

[0006] The purpose of this invention is to provide a folding umbrella with stable creases. This invention is lightweight, easy to carry for a long time, and solves the problem of hard support pieces wearing down the umbrella fabric.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A folding umbrella with stable creases includes an umbrella fabric, an umbrella handle, and a foldable frame; the foldable frame is mounted on the umbrella handle, the umbrella fabric is fixedly covered on the outer surface of the foldable frame and folds together with the foldable frame, and the umbrella fabric is fixedly provided with fixing layers on both sides of the crease along the circumferential direction of the umbrella handle, and the outermost fixing layer has an extension along the radial crease direction of the umbrella fabric on the side away from the foldable frame.

[0009] Furthermore, the fixing layer is fixed to the umbrella fabric by screen printing of the coating.

[0010] Furthermore, the fixing layer is disposed between the two foldable skeletons.

[0011] Furthermore, the width of the crease is 0.2cm-1cm.

[0012] Furthermore, the number of foldable skeletons is at least 5.

[0013] Furthermore, the foldable frame is at least 19 inches long.

[0014] Furthermore, the length of the fixing layer ranges from 1cm to 8cm.

[0015] Furthermore, the umbrella fabric has at least one circumferential fixing layer.

[0016] Furthermore, the fixing layer is made of a waterproof coating.

[0017] Furthermore, the protrusion of the fixing layer faces the umbrella handle.

[0018] After adopting the above technical solution, the present invention has the following beneficial effects:

[0019] This invention utilizes a screen-printed coating to create a fixing layer on both sides of the umbrella fabric crease, replacing the rigid support sheet structure of existing technologies. This significantly reduces the overall weight of the umbrella, making it easier for users to carry for extended periods. The fixing layer, secured to the umbrella fabric via screen printing, also avoids the squeezing and wear caused by the edges of the rigid support sheet in existing technologies, thus extending the umbrella fabric's lifespan and solving the problem of low durability. Furthermore, this invention eliminates complex components such as torsional elastic elements, resulting in a simpler structure and reduced production costs. The outermost fixing layer extends along the radial crease direction of the umbrella fabric, effectively guiding the fabric to fold along the predetermined crease direction during folding, improving crease stability.

[0025] Please see Figure 1 A folding umbrella with stable creases includes an umbrella fabric 1, an umbrella handle 2, and a foldable frame 3. The foldable frame 3 is installed at equal intervals around the umbrella handle 2. The umbrella fabric 1 is fixedly covered on the outer surface of the foldable frame 3 and is folded together with the foldable frame 3. Fixing layers 4 are fixed on both sides of the crease along the circumference of the umbrella handle 2. The outermost fixing layer 4 has an extension 40 along the radial crease direction of the umbrella fabric 1 on the side away from the foldable frame 3.

[0026] Preferably, the fixing layer 4 is fixed to the umbrella fabric 1 by screen printing of coating. The screen printing process has the advantages of precise local processing and controllable coating thickness.
