Door handle {Door handle}

The present invention relates to a door handle that is easy to install and does not come off after installation, and is particularly easy to install on a door of a storage cabinet or furniture door of a sink, To the door handle.

As Korea's kitchen culture changes into a sheltered structure, most household kitchens use a sink. The sink has not only a sink for washing dishes but also a storage room for storing pots, frying pans, and pots. The storage compartment is formed at the lower part of the sink and the upper part of the sink. The doors of the cabinets thus formed are of the sliding door type and the hinged door type, but normally the hinged door type is used.

In the case of forming the storage door by a hinged method, the handle is usually attached to the outer surface of the storage door, and the attachment of the handle is usually done by using a physical fastening means such as a nail or a screw. As described above, when the handle is attached to the door of the cabinet by using a physical fastening means such as a nail or a screw, it takes a lot of time because it is made by a person's hand and it is difficult to attach the handle to a certain position, If the handle is attached to the position, the appearance may be poor.

Accordingly, as shown in Fig. 1, in the prior art, there is a case where the knob G is entirely disposed along the longitudinal side of the opening / closing part of the door of the casement type. In this case, it is not necessary to precisely position the handle so that the installation is easy. It is known in the art to mount the handle in such a manner as disclosed in Japanese Laid-Open Patent Application No. 10-2005-0098737 (2005.10.12) and Open Utility Model No. 20-2009-0006159 (June 22, 2009). In the above public utility model, a " C "-shaped door mounting groove 1 is formed on the handle so as to be fitted and fixed to the edge of the opening and closing part of the door of the cabinet. 50 are fitted and fixed to the edge portions of the opening and closing portions of the cabinet door.

The above-mentioned knobs of the prior art can be easily installed without using any fixing means such as a screw or a nail at the edge of the opening and closing part of the door of the cabinet. However, the above-mentioned knobs of the prior art can be easily removed during use because the "C" -shaped fastening portion is simply fitted in the door, and if the releasing and fitting are repeated, the handle is loosened so that the handle can not be firmly attached to the cabinet door .

Therefore, it is desirable to provide a handle for a door of a storage door which is easy to install on a door of a storage space without any separate fixing means like a handle of the prior art, and hardly gets lost when installed on the storage door.

Accordingly, it is an object of the present invention to provide a door handle that can be easily installed without using a separate fastening means on a door of a sink cabinet or furniture, and can be fixed firmly when installed.

In order to accomplish the object of the present invention, the door handle according to the present invention includes a grip portion for holding a human hand for opening and closing a door, a fastening portion formed integrally with one end of the grip portion, Wherein the fastening portion includes a single body integrally formed with the grip portion and a first and a second extension portions extending from both sides of the integrally formed portion and contacting the surface of the door, And protrusions are formed on the inner surfaces of the first and second extension portions, which are brought into contact with the front and rear surfaces of the door when the door is fitted to the edge portions of the door. The first and second extension portions of the sink base handle fastening portion are formed to be curved inward so that when the handle fastening portion is installed on the door of the sink, the first and second extension portions, which are in contact with the front and rear surfaces of the door, Make sure to press the front and back of this door.

The distance between the central portions of the extending portions of the fastening portions of the door handle according to the present invention is smaller than the thickness of the door inserted into the fastening portions and a plurality of projections are formed on the inner surfaces of the extending portions of the fastening portions, The protrusions penetrate into the surface of the door by the pressing force generated by the central portion of the extensions formed to be smaller than the thickness of the door so that strong coupling force is exerted between the protrusion and the surface of the door So that there is no possibility that the door handle is detached from the door during use. Therefore, the life of the door handle is lengthened, so that the maintenance of the furniture hardly occurs.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a perspective view showing a door handle which is easy to install according to the present invention and which is not released, FIG. 3 is a sectional view showing a cross section of the door handle according to the present invention, and FIG. 4 is a sectional view showing the door handle according to the present invention, And Fig.

As shown in FIG. 2, the door handle 100 according to the present invention includes a grip portion 10 that can be held by a human hand, and a handle portion 10 that is integrally formed at one end of the grip portion and is fitted to one side of the door And a fastening portion 20.

When the door handle according to the present invention is installed in the door of the sink storage cabinet, the grip portion 10 is for holding a person to open and close the door of the storage cabinet, and is provided with a groove for allowing fingers to be gripped.

The fastening portion 20 is integrally formed at one end of the grip portion. The opening portion of the " C "-shaped shape is fitted to the edge of the door of the sink cabinet.

The construction of the door handle 100 according to the present invention will be described in detail with reference to FIG. 3 is a cross-sectional view of the door handle according to the present invention.

3, the door handle comprises a grip portion 10 and a fastening portion 20, and a space S is formed in the grip portion 10 so as to be held by a human hand. The fastening portion is integrally formed with the grip portion. The fastening portion includes an integrally formed portion 21 integrally formed with the grip portion, first and second extended portions 21 and 22, which are in contact with both surfaces of the door extending from both sides of the integrally- Quot; C " -shaped cross section composed of the first and second regions 22 and 23. And the one side portion of the door is inserted into the "C" -type opening portion and the door handle is fixed to the door. The distance D between the outermost edges of the first and second extending portions of the fastening portion according to the present invention is formed to be equal to the thickness of the door but the inside of the first and second extending portions is formed to be smaller than the thickness of the door . That is, as shown in the figure, the middle portions of the first and second extensions are formed to be slightly curved inward. Therefore, when the door is inserted and fastened to the fastening portion, the middle portion of the first and second extending portions of the fastening portion presses both sides of the door so that the door can not be easily detached from the fastening portion.

On the other hand, even if the door is inserted and fixed to the fastening portion configured as described above, there is a case that the door may be detached from the fastening portion during use. In order to prevent the door from being separated from the fastening portion, A protrusion 24 having a triangular cross section, preferably a triangular cross section, is formed on the inner side of the portions. As can be seen from the enlarged view of the portion A in Fig. 3, the projecting portion 24 has a triangular cross-section, and the hypotenuse 24'1 thereof is configured to be directed in the direction in which the side portion of the door rushes into the fastening portion. The hypotenuse 24'1 is formed in a round shape rather than a straight shape. The reason why the hypotenuse is formed in a round shape is that the side portion of the door can be easily inserted into the fastening portion.

4, when the side of the door to be fastened is inserted into the fastening portion, the side of the door is smoothly inserted into the fastening portion due to the hypotenuse 24'1 of the rounded projection 24, do. The protruding portions 24 formed on the inner surfaces of the extended portions are pressed by the intermediate portions of the first and second extending portions of the fastening portions formed to be smaller than the thickness of the door, It is possible to penetrate into the surface of the door.

As such, when the protrusions 24 penetrate into the surface of the door, the vertical sides 24'2 of the protrusions 24 face the portion of the penetrated door vertically. Therefore, the door is not easily separated from the fastening portion by the portion of the door facing the vertical side and the vertical side.

Although the protrusions are illustrated as being in striped form on the inner surfaces of the first and second extensions, the protrusions may be formed in a striped fashion as well as a plurality of individually formed protrusions .

In addition, both ends of the door handle according to the present invention can be finished by a finishing treatment such as a finishing treatment cap, such as a plastic injection material matched to the shapes of both ends, to improve appearance.
