KR101966984B1 - Both type velcro structure for car mat fixing - Google Patents

Abstract

The present invention relates to double-sided Velcro for fixing a car mat, and a manufacturing method thereof. By having a double-sided structure in which hook units with the same pattern are formed on both sides, a bonding condition on the both sides can be maintained so as to prevent a mat from being pushed or separated while stably maintaining the bonding condition. To this end, the double-sided Velcro of the present invention has a structure in which a plurality of hook units (210, 220) are simultaneously injection-molded on each of upper and lower sides, wherein a hook unit (210) on the upper side is larger than a hook unit (220) on the lower side.

Description

{BOTH TYPE VELCRO STRUCTURE FOR CAR MAT FIXING}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a velcro, and more particularly, to a double-sided type velcro for fixing a vehicle mat, which is used as a function for preventing a floor mat of a vehicle from being pushed or released.

Generally, a mat for a vehicle is laid on the floor of a driver's seat, a front passenger's seat and a rear magnet inside the vehicle, thereby preventing the floor of the vehicle from becoming dirty due to foreign matter such as soil.

The conventional automotive mat is widely used as a single plate and a double plate of a bottom mat for collecting foreign matter such as earth or the like.

On the other hand, the conventional automotive mat is fixed on the floor surface by the hot melt adhesive method, but the hot melt is vulnerable to heat, causing problems such as pushing and dropping of the mat in summer.

(Prior Art 1) Korean Patent Registration No. 1629092 (Registered on June 26, 2016) (Prior Art 2) Korean Patent Registration No. 1188070 (Registered on September 26, 2012)

The present invention has been made in order to solve the above problems in the prior art, and it is an object of the present invention to provide a structure of a Velcro in which a hook pattern is simultaneously injection-molded on both sides and a manufacturing method thereof, .

In order to accomplish the above object, the double-sided type Velcro according to the present invention has a structure in which a plurality of hooks are simultaneously injection-molded on the upper surface and the lower surface, respectively, and the hooks on the upper surface are larger than the hooks on the bottom surface.

In addition, the hook portion may have a hook protrusion having a predetermined curvature shape in a bilaterally symmetrical shape.

Further, the hook portion of the upper surface is attached to / detached from the bottom of the vehicle mat, and the hook portion of the bottom surface is attached / detached to / from the nonwoven fabric of the vehicle bottom surface.

In the double-sided type Velcro of the present invention, since the hooks of the same pattern are formed on both sides, the double-sided adhesive state can be maintained, so that the adhesive state is stably maintained and the mat is prevented from being pushed or released.

In addition, since the production of velcro is carried out by the injection molding method, the advantage of mass production of velcro is demonstrated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the construction of a double-sided type Velcro for fixing a vehicle mat according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

The double-sided type Velcro 200 according to the present embodiment is manufactured by injection molding. As shown in FIG. 3, the double-sided type Velcro 200 has a structure in which a plurality of hooks 210 and 220 are provided on the upper and lower surfaces, respectively.

Particularly, the hook portion 210 on the upper surface is provided to be larger than the hook portion 220 on the bottom surface. It can be confirmed that the hook portions 210 and 220 have a symmetrical shape of the upper hook protrusion having a predetermined curvature shape .

1, the upper hook 210 is attached to and detached from the bottom of the vehicle mat 100, and the lower hook 220 is attached to and detached from the lower nonwoven fabric 300.

At this time, it is preferable that a separate velcro tape (not shown) having a loop shape is additionally provided on the bottom surface of the vehicle mat 100 so that the upper surface hook part 210 can be easily attached and detached.

The operation and effect of using the double-sided type Velcro 200 according to the present invention will be described.

The double-sided type Velcro 200 according to the present embodiment is manufactured by injection molding, and the hook portions 210 on both sides are provided with different sizes in the middle of the same pattern.

That is, since the upper hook 210 has a large size, it can maintain a relatively high adhesive force, while the hook 220 of the bottom has a relatively small size.

Therefore, when the double-sided type Velcro 200 of the present invention is used, it can be seen that a stable adhesion state can be maintained with the upper vehicle mat 100 and detachment and attachment with the lower non-woven fabric 300 can be facilitated have.

6 illustrates a configuration according to another embodiment of the present invention. An adhesive coating layer 211 is coated on an upper surface hook portion 210 of a double-sided type Velcro 200, A mixture of phenol resin, phenol resin, epoxy resin, polyurethane, and carbon powder.

Further, nano silver and benzyl acrylate are preferably added to the adhesive coating layer 211 in order to improve the functionality.

That is, at this time, 20 to 40 wt% of xylene resin, 10 to 30 wt% of epoxy resin, 10 to 30 wt% of polyurethane, 10 to 20 wt% of carbon powder, 1 to 10 wt% of nano- By weight, based on the total weight of the composition.

With such a configuration, the adhesive force is further improved by the adhesive coating layer 211 formed on the upper surface hook portion 210, so that the adhesive force to the vehicle mat 100 can be further improved.

Particularly, since the xylene resin mixed in the adhesive coating layer 211 is a thermosetting resin having good water resistance, the bonding force with the epoxy resin is increased to maintain the high durability of the coating layer, and the polyurethane performs the buffering function of the coating layer do.

Since the carbon powder has a characteristic of being resistant to corrosion and heat resistance, it is possible to prevent deformation or dropout of the coating layer due to an increase in ambient temperature.

On the other hand, the addition of the nano-silver component prevents insect accessibility due to the insecticidal and sterilizing function, and benzyl acrylate prevents the aggregation of the xylene resin through activation of the xylene resin, so that the coating layer has a uniform uniform thickness It helps to keep it.

Therefore, when the adhesive coating layer 211 is formed on the upper surface hook portion 210, it is possible to maintain a strong adhesion state with the vehicle mat 100 because the velcro adhesive property is further improved.

Although specific embodiments of the present invention have been illustrated and described above, it is to be understood that the double-sided Velcro structure of the present invention can be variously modified by those skilled in the art.

For example, in the above-described embodiment, the shape of the hook-and-loop hook portion is specified and represented in the drawing, but the concrete shape and the shape of the hook portion can be slightly differently formed.

Therefore, it should be understood that such modified embodiments should not be individually understood from the technical spirit and scope of the present invention, and such modified embodiments should be included in the appended claims of the present invention.
