Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a hook-and-loop component, and more particularly to a hook-and-loop component embedded with a foam material in a mold.

2. Description of the Prior Art

The hook-and-loop strip in prior art is invented by a Swiss engineer George de Mestral in accordance with the idea of burrs. Hook-and-loop strip is configured to connect a component with tiny hooks and another component with hair loops together. When the hooks and loops are pressed together, the two pieces fasten or bind together.
The hook-and-loop strip is easy to assemble and detach. In recent year, the hook-and-loop is usually applied to operate in coordination with other components. When the hook-and-loop strip is used with a foam component, such as a cushion or chair cushion, the hook of the hook-and-loop strip is faced to outside. The hook-and-loop strip is combined with the chair cushion for connecting to another component with a corresponding hair loop. The manufacturing method of the hook-and-loop strip and the chair cushion is to put the hook-and-loop strip in a predetermined position of a mold, and a foam material is filled therein. After the foam material is solidified, the hook-and-loop strip and the chair cushion are formed together.
However, the hook of the hook-and-loop strip used in the chair cushion is a hard material. In order to protect the hook being not covered by the foam material, it is necessary to include some extra works. For example, a disclosure in US patent No. 5,061,540 includes an elastic seal portion to prevent the foam material filling into the hook during the foaming process and also includes a special mold to protect the hook. But extra works require extra manufacturing time, and it increases manufacturing cost.

SUMMARY OF THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENT

A hook-and-loop component embedded with a foam material and a cushion thereof are disclosed in the present invention. The detailed description of the present invention will be discussed in the following embodiments, which are not intended to limit the scope of the present invention, but can be adapted for other applications. While drawings are illustrated in details, it is appreciated that the quantity of the disclosed components may be greater or less than that disclosed, except expressly restricting the amount of the components.
Please refer to FIG. 1A and FIG. 1B, which are respectively illustrating a view and an A-A line sectional view of FIG. 1A of a hook-and-loop component in one embodiment of the present invention. The hook-and-loop component 1 includes a band body 10, a plurality of hair hoops 30 and a magnetic material 20. The band body includes a first surface 101 and a second surface 103 and the first surface 101 and the second surface 103 are opposite to each other. The material of the band body is nonwoven fabric or fiber fabric and includes a plurality of pores 105. The hair loops 30 are disposed on the first surface 101 of the band body 10 and include an interval D from an edge 1011 of the first surface 101. In addition, in the second surface 103 which is opposite to the first surface, the magnetic material 20 is disposed on the corresponding position of the hair loops 30. The magnetic material 20 is preferred to be powder material to include an even magnetic effect and the main material thereof is preferred to be metal powder or metal alloy powder. It is important for the magnetic material to be connected by a magnet.
Thereafter, please refer to FIG. 2A, it is a view illustrating hook-and-loop component is embedded with a foam material in one embodiment of the present invention. Because the hook-and-loop component 1 is configured to be embedded in a foam material (not shown) and exposed the hair loops 30 for connecting, a mold is provided to fix the hook-and-loop component 1 and the foam material (not shown) can form on the hook-and-loop component 1. As shown in FIG. 2A, when the hook-and-loop component 1 and the foam material (not shown) are embedded together, the first surface 101 of the hook-and-loop component 1 is reversed and disposed on the mold 40. The mold 40 includes a magnet 401 and the magnet 401 will be attracted by the magnetic material 20 on the hook-and-loop component 1 to connect the reversed hook-and-loop component 1. In addition, because the hair loops 30 are soft fiber material, the hair loops 30 will be pressed between the reversed hook-and-loop component 1 and the mold 40 when the reversed hook-and-loop component 1 and the mold 40 are connected together. The first surface 101 of the hook-and-loop component 1 are connected together because of the magnetic force between the magnet 401 and the magnetic material 20 and there is no gap existed therebetween.
Now, please refer to FIG. 2B, it is a view illustrating the hook-and-loop component is foam filling within the mold in one embodiment of the present invention. As shown in FIG. 2B, during the foaming process, the foam material will be filling with the pores 105 of the band body 10 in the hook-and-loop component 1. When the pores 105 is filled with magnetic material 20 and the hair loops 30 is connected to the mold 40, there is no gap existed for the foam material filling therein. Therefore, the foam material will not be filled within the pores 105, which includes magnetic material 20 in the band body 10 and the corresponding hair loops 30.
Moreover, in the description above, there is an interval D between the hair loop 30/the magnetic material 20 and the edge of the first surface 101 and the second surface 103. When the hook-and-loop component 1 is attracted with the magnet 401, a gap 50 is formed in the area without the magnetic material 20. During the foaming process, the foam material will be filled within the gap 50. But the foam material are only filled within the space of the gap D and will not be filled in the hair loop 30, which is attracted by the magnet 401. In other words, the foam material is only embedded within the pores 105 within the interval D of the hook-and-loop component 1 so as for the foam material to cover the edge 1011 of the first surface 101. According to the foaming process described above, not only the hook-and-loop component 1 is fixedly embedded within the foam material, but also the hair loops 30 are protected from polluting by the foam material during the foaming process. In the present invention, the number, shape or position of the magnet 401 in the mold 40 is not limited herein, as long as the magnet 401 can connect the hook-and-loop component 1.
