DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

With reference to FIGS. 1 and 2, a D-type screwing assembly for furniture according to a first embodiment of the present invention comprises:

a retaining member 3 including a hole 31 defined in the retaining member 3, a plurality of ribs 32 defined on two sides of the retaining member 3, and a slot 33 formed on a top end of the retaining member 3;

a screw member 4 including at least two orifices 41 defined on a head end 48 of the screw member 4 and a thread section 42 formed on the screw member 4 so as to screw with the hole 31 of the retaining member 3;

a rotary member 5 including at least two posts 51 extending outwardly from a front end of the rotary member 5, a number of the at least two posts 51 corresponding to that of the at least two orifices 41 of the screw member 4 so that the at least two posts 51 of the rotary member 5 are fitted into the at least two orifices 41 of the screw member 4 correspondingly.

Each post 51 of the rotary member 5 is a polygonal column or a circular column, and a shape of each orifice 41 of the screw member 4 corresponds to that of the each post 51.

As shown in FIGS. 3-5, a first wooden component 1 is connected with a second wooden component 2, wherein at least one retaining member 3 is fixed in at least recess of the first wooden component 1, and a notch 33 is used to adjust a direction of the at least one retaining member 3, and the second wooden component 2 has a circular aperture 21 to fit with at least one screw member 4 so that the at least one screw member 4 is rotatably coupled with the at least one retaining member 3, thus connecting the first wooden component 1 with the second wooden component 2. Thereby, when a thread section 42 of the at least one screw member 4 is inserted through the second wooden component 2, the at least one screw member 4 is inserted through the circular aperture 21 of the second wooden component 2, thereafter the thread section 42 of the at least one screw member 4, which is inserted through the second wooden component 2, is screwed with the at least one retaining member 3. i.e., the thread section 42 of the at least one screw member 4 is fitted into a hole 31 of the at least one retaining member 3, and then the at least two posts 51 of the at least one rotary member 5 are fitted into the at least two orifices 41 of the at least one screw member 4, and the at least one rotary member 5 is rotated so that the thread section 42 of the at least one crew member 4 is screwed in the hole 31 of the at least one retaining member 3, hence the first wooden component 1 and the second wooden component 2 of the wooden furniture (such as a cabinet) are connected together easily. In addition, when the at least one screw member 4 is rotatably screwed into the at least one retaining member 3, the at least one rotary member 5, which is fitted on the at least one screw member 4, is removed so as to store the at least one rotary member 5, thus saving a using space.

As illustrated in FIG. 6, a number of the at least two posts 51 of the rotary member 5 of a D-type screwing assembly for furniture is two according to a second embodiment of the present invention.

FIG. 7 is a perspective view showing a retaining member 3 and a screw member 4 of a D-type screwing assembly for furniture according to a third embodiment of the present invention. The retaining member 3 includes a thread extension 33 extending outwardly therefrom, and the screw member 4 includes an opening 43 defined therein so as to mate with the thread extension 33 of the retaining member 3.

FIG. 8 is a perspective view showing a retaining member 3 and a screw member 4 of a D-type screwing assembly for furniture according to a fourth embodiment of the present invention. The retaining member 3 is a circular column and has a hole 31, a plurality of ribs 32 arranged around an outer wall of the retaining member 3, and a slot 33 formed on a distal end of the retaining member 3.

With reference to FIGS. 9-11, the D-type screwing assembly for furniture according to the fourth embodiment of the present invention also comprises a screw member 4. The screw member 4 includes a cylinder bore 44 defined in a head end 48 thereof, a rectangular portion 45 formed on one side of an inner wall of the cylinder bore 44, a rectangular pore 46 arranged on another side of the inner wall of the cylinder bore 44 and communicating with the inner wall of the cylinder bore 44, and a circular pore 47 defined on a front rim of the cylinder bore 44.

The D-type screwing assembly of the third embodiment also comprises a rotary member 5. The rotary member 5 includes an acting end 52, a rectangular groove 53 formed on one side thereof, and two semi-circular bosses 54 fixed on another side thereof.

Thereby, when a thread section 42 of the screw member 4 is inserted through a second wooden component 2, the screw member 4 is inserted into a circular aperture 21 of the second wooden component 2, thereafter the thread section 42 of the screw member 4 outsides the first wooden component 1 is screwed with the retaining member 3, i.e., the thread section 42 of the screw member 4 outsides the second wooden component 2 is fitted into the hole 31 of the retaining member 3, and then the rotary member 5 is retained in the cylinder bore 44 of the screw member 4, one semi-circular bosses 54 of a front end of the rotary member 5 is fixed in the circular pore 47 of the screw member 4, and the rectangular groove 53 of the rotary member 5 retains with the rectangular portion 45 of the screw member 4, the rotary member 5 is rotated so that the thread section 42 of the screw member 4 is rotatably screwed with the hole 31 of the retaining member 3, hence the first wooden component 1 and the second wooden component 2 of the wooden furniture (such as a cabinet) are connected together. Thereafter, the rotary member 5 is pushed into a bottom end of the cylinder bore 44 and the two semi-circular bosses 54 thereof are retained into the rectangular pore 46 of the screw member 4, or the rotary member 5 is removed and then is stored, thus saving a using space.

While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
