Abstract
TITLE: AN ANGLE COUPLING STRUCTURE FOR KNOCKDOWWN
CABINETS
ABSTRACT OF THE DISCLOSURE
An angle coupling structure for knockdown cabinets includes an angle coupling, a plurality of connectible sections, and a plurality of securing aid. Within each of the connectible section, an elongate chamber is formed to receive a connecting rod projecting from the angle coupling and an elongate recess is formed generally below the elongate chamber to receive one of the securing aids and permitting the same to slidably move therein. An elongate slot is formed on the wall between the chamber and the recess. While a screw is put through the hole preformed on the securing aid, it may pass the elongate slot to screw into the hole formed on the connecting rod precisely due to the adjustable position of the securing aid. The connectible sections, angle coupling, and the securing aids are thus joined together tightly.

Description
2~2~3~
The present invention relates to an angle coupling structure for a knockdown cabinet.
It is an object of the present invention to provide an angle coupling structure for knockdown cabinets assembled with plural connectible sections. Within each of such connect-ible sections a connecting rod retainer and a securing aid retainer are preformed to be capable of receiving a connect-ing rod and a securing aid, respectively. An axially extend-ing longitudinal slot is formed on the wall between the connecting rod retainer and the securing aid retainer so that screws may be put through round holes formed on the securing aid and through the longitudinal slot to precisely screw into the hole formed on the connecting rod projecting from the angle coupling by sliding the securing aid in the securing aid retainer to a proper position.
According to a broad aspect of the present invention there is provided an angle coupling structure for knockdown cabinets. The coupling structure comprises an angle coupling provided with plural projecting connecting rods, each of which is provided with a plurality of screw holes. A plurality of connectible sections, each of which is formed with an axially extending chamber having a cross-section which is the same as that of the connecting rods is provided for the insertion of the connecting rod thereinto. An axially extending recess is formed generally below the axially extending chamber with an axially extending elongate slot formed on a wall between the chamber and the recess. A plurality of securing aids, 2~2a~32 each of which has a cross-section which is the same as that of the axially extending recess, is provided for insertion into the recess and may be slidably moved therein. A plura-lity of round holes is formed to correspond to the screw holes formed on the connecting rod, respectively, for the passage of screws therethrough to join and secure the securing aid. The connecting rod and the connectible section via the elongate slot and the screw holes on the connecting rod provide for the connectible section to be tightly and securely joined with said angle coupling without leaving any gaps therebetween.
A specific embodiment of the present invention will now be described with reference to the accompanying drawings in which:
FIG. 1 is a three-dimensional analytical perspective of the present invention;
FIG. 2 is a plan view showing the joining of the connectible section with the connecting rod with a plurality of screws through the securing aid as well as the longitudinal slot;
FIG. 3 is a three-dimensional analytical perspective of a conventional angle coupling structure for a knockdown cabinet; and FIG. 4 is a plan view showing the joining of a connecting rod with a connectible section in a conventional coupling structure.
2 ~ 3 2 Figures 3 and 4 illustrate the prior art knockdown cabinet assembled with a plurality of connectible sections with the assembly of such connectible sections being achieved by an angle coupling 100 having a plurality of connecting rods 101, each of which may extend into a connecting rod retainer 201 preformed in a connectible section 200. A plura-lity of round holes 202 are present on an inner wall of the connecting rod retainer 201 in such a manner that such holes will correspond to threaded screw holes (not shown) preformed on the connecting rods 101 so that screws 300 may be screwed into therethrough to join and fasten the connectible sections and the angle coupling (as shown in Figure 4). However, it is frequently found that the holes 202 do not always match with the present threaded holes on connecting rods 101 when the connecting rods 101 are inserted into the connecting rod retainers 201. Whenever this situation happens, the user will need to adjust by himself the location of the angle coupling 100 to match the two sets of holes and fasten them with screws, or, he will have to send back the product to the seller re-drilling new and matchable hole(s). The former solution will result in a gap between each angle coupling 100 and connectible section 200 while the second solution will cause much inconvenience to the user.
As shown in Fig. 1, an angle coupling structure for knockdown cabinets has an angle 1, a plurality of connectible sections 2, and a plurality of securing aids 3. A plurality of connecting rods 11 having plural preformed screw holes 111 2 ~ 2 are projecting from the angle coupling l; each of the connect-ible sections 2 is provided with a connecting rod retainer to receiving a connecting rod 11, and a securing aid retainer 22 formed generally below the connecting rod retainer 21 to receiving a securing aid 3. An axially extending longitudinal slot 23 is formed on the wall between the connecting rod retainer 21 and the securing aid retainer 22. A plurality of round holes 31 provided on the securing aid 3 substantially correspond to the screw holes 111 formed on the connecting rod, respectively. With this arrangement the securing aid 3 may be inserted into the securing aid retainer 22 to freely slidably move therein to be adjusted until the holes 31 on it may precisely match with those holes 111 on the connecting rod 11 thereby enabling a screw 32 to pass through the hole 31, the longitudinal slot 23, and the screw hole 111 to screw the connectible section 2, securing aid 3, and the angle coupling 1 together tightly without leaving any gap between the angle coupling and the connectible section 2.
The specifications for the screw 32, round hole 31, longitudinal slot 23, and screw hole 111 are all the same to enable their joining. However, the size of the longitudinal slot 23 may be slightly larger while the screw 32 may be used together with washers. Since most of these are known by those who are familiar with this art, they will not be further described here. In addition, the cross-section of the connecting rod 11 corresponds to that of the connecting rod 2~20~2 retainer 21 while the cross-section of the securing aid 3 corresponds to that of the securing aid retainer 22. Such cross-sections may be properly changed while the same effect of joining may still be achieved.
While a specific embodiment of the present invention has been shown and described in detail to illustrate the application of the principle of the invention, it will be understood that the invention may embody others without departing from such principles.
