Description A CORNER CAP Technical Field
[1] The present invention relates to a corner cap which includes a coupling clip inserted into a coupling hole formed on the corner of a frame assembly to which vertical and horizontal frames are coupled and fixed, a right-angled groove formed on the inner surface thereof for inserting and fixing an angled corner of a glass, door or mirror thereto, and an outer surface curved, thereby providing users with a sense of stability by removing a sharp portion of the corner, improving productivity by making the coupling and assembly easy, and increasing a desire of buying by providing a beautiful outward appearance. Background Art
[2] In general, a frame made of aluminum (so called "chassis") has been widely used for a door of a piece of furniture, mirror or window since it is light, easy to manufacture and cheap and provide a beautiful sense. A conventional frame made of wood material is easy to process but has several problems in that it is deteriorated in productivity due to lots of works, changed in quality due to humidity and expensive. So, people prefer the aluminum frame to the wooden frame in various fields. Such a aluminum frame is produced in such a way that ends of a vertical frame and a horizontal frame are cut at an angle of about 45° an frame assembly of a ,J ' shape is fit on the cut diagonal plane, and the vertical and horizontal frames are coupled with each other, so that corners of the frames are connected with one another in the form of the ,J ' shape. Thus, a rectangular frame is formed, and the frame and the frame assembly are fastened to each other via bolts. Each corner formed by coupling the vertical and horizontal frames, each of which is cut at an angle of 45° with each other has an angle of 90° and has a very sharp cut surface, so that the sharp surface may injure a user when the user collides grazes it. To solve the above problem, Korean Utility Model Registration No. 291500 discloses an assembly device for furniture which has buffering means mounted on the corner of a frame. In Korean Utility Model Registration No. 291500, vertical and horizontal frames are cut at an angle of 45° and their end portions, namely, sharp end portions, are cut in a prescribed size, and thereby, the coupled corner between the vertical and horizontal frames has a 'Λ' shaped groove. A coupling member for coupling the vertical and horizontal frames with each other includes a corner cap formed integrally with the coupling member, made of resin material and inserted into the 'Λ' shaped groove, so that the sharp corner of the vertical and horizontal frames can be covered with the rounded corner cap made of the resin
material by mounting the comer cap to the comer of the vertical and horizontal frames. However, the prior art has several problems in that a protruding bar may be easily broken during safekeeping or delivery and it is difficult to couple the coupling member with the vertical and horizontal frames since an end portion of the comer cap protrudes long. To overcome the above problems, Korean Utility Model Registration No. 20-0335005 which was invented by the same inventor as Korean Utility Model Registration No. 291500 discloses another comer cap. In Korean Utility Model Registration No. 20-0335005, the comer cap includes an assembly of a ,J ' shape for coupling frames and having coupling holes formed on the comer thereof, and a comer member having coupling bars formed integrally with the comer member and inserted into the coupling holes. The assembly formed by inserting the coupling bars into the coupling holes is fit on the vertical and horizontal frames, and thereby, a rectangular frame is formed. However, the prior art has a disadvantage in that the coupling bars inserted into the coupling holes, which are formed vertically, in a straight line are easily moved forwardly even by weak power. That is, the coupling bars are easily slipped or separated from the coupling holes when weak power is applied to the comer member mounted to the coupling hole or the comer cap collides against the framework of a door.

[28] Mode for the Invention
[29] Fig. 5 is an exploded perspective view of the second preferred embodiment of the present invention, Fig. 6 is a plan sectional view showing a coupled state of Fig. 5, and Fig. 7 is a side sectional view showing the coupled state of Fig. 5. Referring to the drawings, in the second preferred embodiment, the body 40 has a right-angled groove 40-1 formed on the inner surface thereof so that the angled comer of the glass, door or mirror inserted into the glass fixing part of the vertical and horizontal frames 10 and 20 which are fixed with each other at right angles can be easily inserted and fixed into the right-angled groove 40-1. At this time, the body of the comer cap may selectively use a protective cover plate 40-2 formed on the top thereof for protecting the comer of the glass according to whether or not the vertical frame 10 or horizontal frame 20 has a wing member formed on a glass fixing part 21. Fig. 8 shows a modification of the second preferred embodiment of the present invention. As shown in Fig. 8, the comer cap does not have the right-angled groove 40-1 and the protective cover plate 40-2, whereby the comer cap can easily fix the glass to the 'D'shaped frame. The soft buffering member mounted and fixed to the coupling ring 44 formed on the end of the fixing piece 43 can be easily exchanged with a new one when it is damaged or broken due to collision. As shown in Fig. 7 which is the side sectional view showing the state where the comer cap is snap-fit into the coupling hole, the body of the comer cap includes a bar-shaped coupling clip 42-2 formed inside the buffering member and inserted into a coupling hole 31-2 formed on the frame of the assembly 30, so that the buffering member fastened to the frame is not relieved from the frame. At this time, at least one coupling clip can be formed, and designed in various shapes and sizes (in the form of an integrally elongated shape or an oval shape). As shown in Fig. 5, the buffering member 45 and the fixing piece 43 can be formed integrally with each other and fixed to the frame in order to make the assembly of the comer cap easy. The buffering member 45 can be adhered on the surface of the frame with an adhesive. In the drawings, unexplained reference numeral 32 designates a coupling bolt hole for coupling the assembly to the frame, 21 designates the glass fixing part, and 50 designates a mirror or a door plate which is called the 'glass' in the present invention. Fig. 10 shows a third preferred embodiment of the present invention. The comer caps (al) and (a2) shown in Fig. 10 respectively have coupling clips formed in a vertical direction. In this case, the assembly includes a space formed on the lower portion
thereof for inserting the coupling clip (Fig. 10), and a coupling hole formed inside the assembly for inserting and fastening the coupling clip 42-2. The vertically formed coupling clip may have various lengths and shapes according to the size and shape of the assembly. The comer cap which has the horizontally formed coupling clip as shown in Figs. 1 to 9 and Figs. 12 to 14 can couple and fix the vertical and horizontal frames to the frame assembly without regard to whether or not the comer cap is snap- fit into the coupling hole 31 of the assembly 30, but the comer cap which has the vertically formed coupling clip as shown in Fig. 10 can couple and fix the vertical and horizontal frames with each other only when the comer cap is snap-fit into the coupling hole 31 of the assembly 30. Furthermore, in Fig. 10, to easily assemble the comer cap, it is preferable that the buffering member is mounted on the lower portion of the body of the comer cap (in the drawing). Figs. 12 and 13 shows a fourth preferred embodiment of the present invention. In the drawings, the comer cap includes a buffering member for reducing impact between a door and the framework of the door and a buffering member for protecting the glass by reducing impact between the outer glass surface and a wall. The comer cap according to the fourth preferred embodiment may have the horizontal coupling clip formed in various shapes as shown in Figs. 1 to 9. As shown in Figs. 12 and 13, if the buffering members are mounted on both sides of the body of the comer cap, it is preferable that the coupling clip is formed inside the body in consideration of convenience in assembly. The fixing piece 43 according to the present invention may be selectively formed short or long as occasion demands. The function and effects of the comer cap manufactured according to the present invention will be described in more detail. Fig. 1 is an exploded perspective view showing a used state of the present invention, and Fig. 2 is a plan sectional view showing a state where the comer cap is snap-fit into the coupling hole of the assembly. As shown in the drawings, the present invention is made of synthetic resin material or aluminum, has an outer surface curved 40-3, and is mounted on the comer of a frame of a piece of furniture, a glass window or a door of furniture. The present invention has an object to provide the comer cap which is easy to assembly and not separated from the frame after the assembly. In the comer cap according to the present invention, the end portions of the vertical and horizontal frames 10 and 20 are cut at an angle of 45° and the end portions, namely the sharp end portions, are cut in a prescribed size and coupled with each other, whereby the vertical and horizontal frames form a 'Λ' shaped groove formed on a comer portion therebetween. After that, the vertical and horizontal frames having the 'Λ' shaped groove are mounted and fixed to coupling holes formed on the both wing parts of the assembly 30. When the frames are coupled in the form of a rectangle, the comer portion between the horizontal and vertical frames has the 'Λ' shaped groove, and the coupling hole 31 formed on the comer of the assembly 30 is
exposed through the 'Λ' shaped groove. The body 40 of the comer cap is inserted into the hole, and the stopper 41 formed on the front end of the coupling clip 42 is snap-fit into the coupling hole 31 by pressing the body 40 of the comer cap, so that the body 40 is fastened to the comer of the coupled portion of the horizontal and vertical frames, and thereby, the present invention can provide the comer which is smoother and more beautiful. The comer cap according to the present invention can coupled the horizontal and vertical frames with each other in a state where the body 40 is snap-fit into the coupling hole 31 formed on the assembly 30 without regard to the coupling order (excluding the embodiment of Fig. 9). At this time, a user can selectively determine the assembly order in consideration of saving of the assembly period and convenience. At this time, the soft buffering member 45 is coupled and fixed to the coupling ring 44 formed on the end portion of the fixing piece 43 formed integrally with the body 40, and is in close contact with the surface of the frame. The buffering member 45 is located at a friction portion between the door and the framework of the door, and is provided to prevent noise by reducing impact between the door frame and the framework of the door when the door is opened or shut. In another embodiment of the present invention, the fixing piece is formed integrally in an extension line of the body of the comer cap, coupling rings are formed at both end portions of the fixing piece, and the soft buffering members are mounted to the coupling rings or formed integrally. As a result, the present invention can prevent noise by reducing impact when friction is generated between the door and the framework of the door, and prevent a damage of the glass or mirror when the glass window is opened and collides against the outer wall in a small space. In the second embodiment shown in Figs. 5 and 6, the bar shaped coupling clip 42-1 is formed inside the buffering member 45, and fastened to the frame coupled to the assembly 30 and the coupling hole formed on the assembly 30, and thereby, the buffering member 45 is not relieved from the frame. In Fig. 4, the buffering member 45 and the fixing piece 43 are formed integrally with each other in order to make the assembly thereof easy. The buffering member 45 can be adhered to the surface of the frame with the adhesive. In Figs. 5 to 7, the comer cap has the right- angled groove 40-1 formed on the inner surface of the body thereof in such a way as to be easily inserted and fixed to the angled comer of the glass, door or mirror inserted into the glass fixing parts of the horizontal and vertical frames coupled with each other at right angles. If the glass fixing parts 21 of the vertical and horizontal frames 10 and 20 respectively have wing members, the comer cap further includes the protective cover plate 40-2 formed on the top thereof for protecting the comer of the glass. The coupling clip 42 having the stopper in one of the embodiments according to the present invention includes at least one coupling bar inserted into the comer of the assembly, or formed integrally with the coupling clip 42 in various sizes or shapes and inserted into
the coupling hole.
