Description

{Dowel for door / window system frame}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail for joining frames for windows, and more particularly to a nail for more firmly joining a window frame.

Generally, custom nails are called hairy or dubos. In the era when old-time wooden frames or window frames were made, they were fixed using cylindrical or square pegs with both ends pointed.

For example, nails or bolts used for joining frames of a door frame or window frame recently. In the present invention, the names of damo and damo are collectively referred to as custom nails.

In recent years, in order to manufacture a door frame or a window frame, a rectangular bar frame is made of a synthetic resin material, and the frame is squarely squeezed to form a door or a window. At this time, And then joining them to the nail. This is because it is difficult to combine the characteristics of a frame and frame connected at right angles, and when a nail or a bolt is used, the nail tip or the head of the bolt is exposed and the appearance is not good.

That is, when the nail is used, one end of the nail is inserted into one frame, and the other end is inserted into the frame at the other end.

However, the disadvantage of the conventional nail is that a hole is drilled in the frame for the engagement of the nail. If the hole is too large, the nail becomes loose and it is difficult to secure the connection. If the hole is small, It has a closed end which is difficult to join because it does not enter.

Even if the frame is properly fitted, since the frame and window frame are made of a frame made of a synthetic resin material, the holes are gradually loosened due to the nature of the frame, and after that, the strength of the frame is weakened and the frame and the window frame may be twisted or damaged. It has necessary disadvantages.

1. Domestic Utility Model Registration 20-0422702

In order to solve the above-described problems, an object of the present invention is to provide a door frame and a window frame (hereinafter referred to as window) which are made of a frame made of a synthetic resin material and are simply coupled to each other by a nail of a cylindrical plastic material, It has the disadvantages that it is easy to detach and it is easily damaged when it is inserted into the frame made of synthetic resin when it is inserted and gradually weakens the bonding force between the nail and the frame so that the durable and robust synthetic resin door frame It is an object of the present invention to provide a nail for joining frames for windows that can form a window frame.

According to an aspect of the present invention, there is provided a bipolar plate having a central bipolar plate and a bipolar plate protruding from both sides of the bipolar plate and having sharp edges, And an insertion hole formed at the center so as to be inserted into the insertion rod of the coupling hole and having a plurality of locking protrusions spaced apart from each other by a predetermined distance on the outer circumferential surface thereof.

The plurality of locking protrusions formed on the outer circumferential surface of the insertion rod are formed in a reverse direction so that the insertion port is easy to insert but not easily separated.

The insertion port is configured such that a diameter of a side thereof contacting the separating plate is large and a diameter of a farthest side of the separating plate is small and a cut section spaced apart from the separating plate is formed in the longitudinal direction.

According to the above-described effects of the present invention, a coupling nail capable of coupling a vertical frame and a horizontal frame of doors and windows made of a synthetic resin material is provided, but the durability and the rigid coupling state can be maintained.

Further, the present invention is a very useful invention that can provide a structure that can be very firmly coupled by being manufactured by separating into a coupling hole and an insertion hole to be inserted into the coupling hole and then combining them.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. Also, the singular forms used herein include plural forms as long as the phrases do not expressly mean the opposite. Means that a particular feature, region, integer, step, operation, element and / or component is specified, and that other specific features, regions, integers, steps, operations, elements, components, and / And the like. Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Commonly used predefined terms are further construed to have meanings consistent with the relevant technical literature and the present disclosure and are not to be construed as ideal or official unless defined otherwise.

The embodiment of the present invention described with reference to the perspective view specifically illustrates an ideal embodiment of the present invention. As a result, various variations of the illustration, for example variations in the manufacturing method and / or specification, are expected. Thus, the embodiment is not limited to any particular form of the depicted area, but includes modifications of the form, for example, by manufacture. For example, the regions shown or described as being flat may have characteristics that are generally coarse / rough and nonlinear. Also, the portion shown as having a sharp angle may be rounded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a nail for joining frames for a window according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of the nailing apparatus of the present invention, FIG. 2 is a perspective view of the coupled state of FIG. 1, FIG. 3 is a sectional view of FIG. 2, and FIG.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The nail 100 according to the embodiment of the present invention includes a separating plate 111 formed at the center and a pair of protrusions 112a protruding from both sides of the separating plate 111 and having sharp edges and a plurality of engaging projections 112a formed at a predetermined interval A through hole 121 formed at the center so as to be inserted into the insertion rod 112 of the coupling hole 110 and a plurality of coupling holes 122 And a pair of insertion openings 120 spaced apart from each other by a predetermined distance.

At this time, the plurality of locking protrusions 112a formed on the outer circumferential surface of the insertion rod 112 are configured to be reversed toward the separation plate 111, that is, the separation plate 111 is formed to have a high level and the opposite side has a low level. This is a structure necessary to maintain a rigid coupling state so that insertion is easy when the insertion port 120 is inserted into the insertion rod 112, but separation is not easy.

At this time, an engaging means corresponding to the engaging projection 112a may be formed on the inner surface of the insertion port 120 to maintain a more rigid engagement state.

The insertion port 120 has a larger diameter on the side facing the separating plate 111 and a smaller diameter on the farthest side of the separating plate so that the insertion port 120 can be easily inserted when inserting the synthetic resin frame into the through hole.

Also, the insertion opening 120 may be formed such that a cutout portion 1230 spaced apart from the insertion opening 120 is formed in the longitudinal direction to be inserted into a frame made of a synthetic resin material, but is not easily separated.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
