Description

Technical Field

[0001] This invention relates to bed frames, and in particular to a retractable bed cover that works in conjunction with a retractable bed frame. Prior Technology

[0002] The bed frames of most electric beds are made of metal, which gives a cold feeling. To make the bed frame feel warmer and more comfortable, a fabric cover can be used to cover it. However, due to the rising transportation and storage costs in recent years, in order to save costs or make the use more flexible, some bed frames are designed with an adjustable width. However, the cover cannot be adjusted to fit the width, so manufacturers need to prepare two sizes of cover to match the bed frame size when consumers purchase or use it. This increases material costs and weakens the product's market competitiveness. Summary of the Invention

[0003] One objective of this invention is to provide a retractable bed sheet that can be extended and adjusted in length or width to match a retractable bed frame.

[0004] To achieve the above objectives, the extendable bed sheet of the present invention is designed for mounting on a bed frame and comprises a front fabric, a side fabric, and a side strip. The front fabric covers the top of the bed frame and includes a main body, a side portion, a connecting portion connecting the main body and the side portion, a first zipper portion disposed between the main body and the connecting portion, and a second zipper portion disposed between the connecting portion and the side portion. The first zipper portion and the second zipper portion are connectable or detachable. The side fabric extends downward from the side portion and is located on a first side of the bed frame. The side strip is located inside the side fabric and below the bed frame. Thus, the bed sheet of the present invention can be extended and retracted to adjust its length or width to accommodate an extendable bed frame. Simple Explanation of the Diagram

[0005] Figure 1 is a perspective view of a retractable bed pack according to a preferred embodiment of the present invention; Figure 2 is a cross-sectional view of a preferred embodiment of the retractable bed pack of the present invention; Figure 3 is a schematic diagram of the unfolded state of the retractable bed pack according to a preferred embodiment of the present invention. Implementation

[0006] The following describes the technical content and features of the present invention in detail with reference to a preferred embodiment and accompanying drawings. As shown in Figures 1-3, a retractable bed cover 1 provided by a preferred embodiment of the present invention is shown. The bed cover 1 is used to be mounted on an adjustable-width bed frame 2. The bed frame 2 is divided into a front bed frame 3 and a rear bed frame 4. The front bed frame 3 and the rear bed frame 4 can be folded together. The front bed frame 3 and the rear bed frame 4 are provided with a plurality of legs 5 at the bottom so that the top surface of the bed frame 2 has an appropriate height for placing a mattress (not shown). The bed cover 1 can be mounted on the front bed frame 3 and the rear bed frame 4. Since the structures are similar, the following description takes the bed cover 1 mounted on the rear bed frame 4 as an example. The bed cover 1 includes a front fabric 10, two side fabrics 20 located on the left and right sides of the front fabric 10 respectively, two side strips 30, and an end fabric 40 located behind the front fabric 10. For ease of explanation, this article uses the direction of the head of the bed in Figure 1 as the front (D1) and the direction of the foot of the bed as the back (D2).

[0007] The cover fabric 10 is applied over the bed frame 2. The cover fabric 10 has a rectangular main body 11, two elongated side portions 12 located on the left and right sides of the main body 11 respectively, two elongated connecting portions 13 connecting the main body 11 and the two side portions 12, two first zipper portions 14 located between the main body 11 and the two connecting portions 13, and two second zipper portions 15 located between the corresponding two connecting portions 13 and the two side portions 12. The first zipper portions 14 and the second zipper portions 15 can be linked together or separated by a zipper head 16.

[0008] The two side fabrics 20 extend downward from the opposite outer sides of the two sides 12. Since the two side fabrics 20 have similar structures, the side fabric 20 located on the left side of the bed frame 2 is used as an example for explanation. As shown in Figures 2 and 3, which are cross-sectional views of the left side of the bed frame 2, the side fabric 20 is located on one of the first side edges 6 (i.e., the left side) of the bed frame 2. The bottom edge of the side fabric 20 extends laterally inward to form a bottom 22.

[0009] The side strip 30 is located inside the side fabric 20 and below the bed frame 2. The side strip 30 has a long strip-shaped core material 32 and a covering material 34 covering the core material 32 and connected to the side fabric 20. In this embodiment, the covering material 34 is connected to the bottom 22 of the side fabric 20 by sewing, but it can also be bonded or fixed together by other means. The core material 32 is a foam material such as foam, and the covering material 34 is a fabric material that can be bonded with hook and loop fasteners.

[0010] To ensure the side strip 30 is more securely positioned below the bed frame 2, a fastener 7 can be provided at the bottom edge of the bed frame 2. This fastener 7 is detachably fixed to the side strip 30. In this embodiment, the fastener 7 is a male hook and loop fastener, which can be fastened to the packaging material 34; that is, the packaging material 34 has characteristics equivalent to a female hook and loop fastener. In this way, the side strip 30 not only provides cushioning and anti-collision functions but also allows the side fabric 20 to be opened, visually increasing the height of the side of the bed frame 2 and enhancing its perceived value.

[0011] The end fabric 40 extends downward from the other side (i.e., the rear side) of the face fabric 10 and is located on the second side 8 (i.e., the rear side) of the bed frame 2. The second side 8 is perpendicular to the first side 6. In this embodiment, the end fabric 40 can be regarded as an extension of the face fabric 10 (including the main body 11, the side portion 12, the connecting portion 13, the first zipper portion 14 and the second zipper portion 15). The structure of the end fabric 40 is similar to that of the face fabric 10.

[0012] When it is desired to adjust the width of the bed frame 2 to increase its width, the first zipper part 14 and the second zipper part 15 can be separated by the zipper head 16, and the connecting part 13 can be unfolded. In this way, the bed cover 1 can be expanded to increase its width, as shown in Figure 3. In this way, the bed cover 1 of the present invention can be stretched and adjusted to match the stretchable bed frame 2. The manufacturer only needs to prepare one bed cover 1 of the present invention to fit the two usage modes of the bed frame 2, which are both wide extension and retraction. Moreover, the adjustment method of the bed cover 1 is simple, and consumers can easily operate it. It is quite convenient to use, thereby achieving the purpose of the present invention.

[0013] Based on the design spirit of this invention, the structure of the extendable bed sheet 1 can have other variations. For example, the length of the bed sheet 1 can be adjusted using a similar structure; the outer fabric 10 can have only one side portion 12 and a connecting portion 13 to expand the width on one side; the side fabric 20 may not have a bottom 22; the edge strip 30 can be directly sewn onto the inner side of the side fabric 20; the edge strip 30 can be made directly from foam material, which can be considered as having only core material 32 without outer packaging material 34; the fastener 7 can be fixed to the edge strip 30 by adhesive, snap-fit, or other means, or the fastener 7 may not be provided, and the edge strip 30 can be positioned under the bed frame 2 solely by the tension of the bed sheet 1 itself. All such easily conceivable structural variations should be covered by the scope of the patent application of this invention.
