BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a house furniture, such as a cabinet, case, wardrobe, closet, cupboard and the like, and, more particularly, to a combination cabinet with a foldable door.
2. Description of the Related Art
A conventional cabinet comprises a cabinet body and a door frame connected with the cabinet body. The door frame includes a track mounted on the cabinet body and two pull doors movably mounted on the track. However, when the pull doors are opened, the pull doors occupy one half of the opening space, thereby limiting the opening space. Alternatively, the door frame includes a single door pivotally mounted on a side of the cabinet body. Thus, when the door is pivoted outward, the cabinet body is opened, and when the door is pivoted inward, the cabinet body is closed. However, when the door is pivoted outward to open the cabinet body, the door protrudes outward from the cabinet body, so that the door will occupy a large space. Alternatively, the door frame includes two juxtaposed doors pivotally mounted on two opposite sides of the cabinet body. Thus, when the doors are pivoted outward, the cabinet body is opened, and when the doors are pivoted inward, the cabinet body is closed. However, when the doors are pivoted outward to open the cabinet body, the doors also protrude outward from the cabinet body, so that the doors will occupy a large space. In addition, a gap is defined between the cabinet body and each of the doors so that a user is easily clamped by the gap between the cabinet body and each of the doors during pivotal movement of each of the doors, thereby causing danger to the user.
BRIEF SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a combination cabinet, comprising at least one pair of door frames, at least one separation bar mounted between the door frames, a pair of fixing seats mounted on the separation bar, and a plurality of pivot pieces each mounted in a respective one of the door frames and each pivotally connected with a respective one of the fixing seats. The separation bar has an upper end and a lower end each provided with a slot for mounting a respective one of the fixing seats. Each of the fixing seats has a side provided with an insert inserted into the respective slot of the separation bar.
According to the primary advantage of the present invention, the separation bar fully seals the gap between the door frames when the door frames are fully expanded, fully folded or inclined relative to each other, thereby enhancing the aesthetic quality of the door frames.
According to another advantage of the present invention, the separation bar closes the gap between the door frames during pivotal movement of the door frames, thereby preventing a person from being clamped or hurt by the gap between the door frames.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

Each of the door frames 1 has an upper end and a lower end each provided with a fixing hole 10 for mounting a respective one of the pivot pieces 2. Each of the door frames 1 has a side provided with a first arcuate portion 11.
Each of the pivot pieces 2 has a first end provided with a shaft hole 20 for mounting a respective one of the bearings 21, and a second end provided with a fixing portion 22 secured in the fixing hole 10 of the respective door frame 1. Each of the pivot pieces 2 has a side provided with a second arcuate portion 23 abutting the first arcuate portion 11 of the respective door frame 1.
The separation bar 4 has an upper end and a lower end each provided with a slot 40 for mounting a respective one of the fixing seats 3. The separation bar 4 has two opposite sides each provided with a third arcuate portion 41 abutting the first arcuate portion 11 of the respective door frame 1.
Each of the fixing seats 3 has two opposite ends each provided with a shaft bore 30. The shaft bore 30 of each of the fixing seats 3 aligns with the shaft hole 20 of a respective one of the pivot pieces 2. Each of the fixing seats 3 has a side provided with an insert 33 inserted into the respective slot 40 of the separation bar 4. The insert 33 of each of the fixing seats 3 has two opposite sides each provided with a fourth arcuate portion 34 abutting the respective third arcuate portion 41 of the separation bar 4.
The combination cabinet further comprises two pairs of shafts 31 each extended through the shaft bore 30 of a respective one of the fixing seats 3 and the shaft hole 20 of a respective one of the pivot pieces 2 to pivotally connect the fixing seats 3 with the pivot pieces 2, and two pairs of fastening members 32 each locked onto a respective one of the shafts 31 to fix the respective shaft 31.
