Description

BACKGROUND OF THE INVENTION

1. Fields of the Invention

The present invention relates to a pet cage, and more particularly, to a door of a pet cage able to be firmly locked or easily unlocked and easily dis-assembled in case of transportation and storage.

2. Descriptions of Related Art

The conventional pet cage 1 as shown in FIGS. 1 and 2 generally includes a cage 10 which is composed of multiple frames or multiple boards welded together. The conventional pet cage 10 has a door frame 11 at the front side thereof and the door frame 11 has a door 12 which is pivotally connected to the door frame 11. A latch 13 is defined respectively at the upper portion and lower portion of the door 12 in order to lock the door 12 and the door frame 11 together. Each of the latches 13 comprises a first part 130, a second part 131 and a bar 132, wherein the first part 130 fixed to the door frame 11 has first holes 1300, the second part 131 fixed to the door 12 has second holes 1310, and the bar 132 is an L-shaped bar able to extend through the first holes 1300 and second holes 1310 to secure the door 12 to the door frame 11. Nevertheless, the cage 10 is fixed so that space will be occupied while transporting and storing. Besides, the bar 132 is not well secured so that the bar 132 may be pushed to open the door 12 by the pet. In order to open door 12, the bars 132 of the latches 13 will be removed one by one from the first parts 130 and second parts 131. Further, the bars 132 may be dropped from the second holes 1310 of the second part 131 if pushing too hard while opening door 12, and the bars 132 may be lost because of that.

The present invention intends to provide a pet cage to eliminate the shortcomings mentioned above.

One of the holes 301 and one of the engaging slots 302 are located at an upper position of the base 30, and the other one of the holes 301 and the other one of the engaging slots 302 are located at a lower position of the base 30. The bar 31 is a U-shaped bar and has two parallel insertion ends 310 and a grip 313 is connected between the two insertion ends 310. Each of the insertion ends 310 of the bar 31 has an oblique face 312 defined in the distal end thereof. The two insertion ends 310 respectively extend through the holes 301 in the two sidewalls of the base 30. A pin hole is defined respectively on the two insertion ends. The two springs 32 are respectively inserted into the two insertion ends 310 and located between the two sidewalls of the base 30. The two pins 33 respectively extend through the two pin holes 311 of the two insertion ends 310 and respectively approach to the sliding slot 300 at the upper and the lower portion of the base 3. One end of the two springs 32 is respectively against the inner literal sidewall of the base 3 and the other one end of the two springs is respectively abutted to the two pins 33. The cover 34 has two hooks 340 extending from each of two sides thereof so as to be engaged with the engaging slots 302 of the base 30 to seal the base 30. The receiving base 35 is fixed to the door frame 2 and located corresponding to the base 30 on the door 21. The receiving base 35 has t To apertures 350 which are located corresponding to the holes 301 of the base 30. The receiving base 35 has an oblique plate 351 extending from an outside thereof.

The top board 4 is connected to the top side of the door frame 2, and the bottom board 5 is connected to the bottom side of the door frame 2. Each of the top board 4 and the bottom board 5 has a wall 40/50 bending from each of four sides thereof. Multiple holes 41/51 are defined through the wall on the front end of each of the top and bottom boards 4, 5. Multiple threaded holes 42, 52 are defined through each of the walls on the rear end and two sides of each of the top and bottom boards 4, 5.

The back board 8 is connected to rear end of each of the top board 4, the bottom board 5, the left board 6 and the right board 7. The back board 8 has multiple holes 80 and each hole 80 of the back board 8 has a bolt 81 extending therethrough which is threadedly connected to the threaded hole 42/52/62/72 of the top board 4/the bottom board 5/the left board 6/the right board 7.

The multiple fasteners 9 securely extend through holes 41, 51, 61, 71 of the door frame 2, the top board 4, the bottom board 5, the left board 6 and the right board 7. As shown in FIGS. 3 and 7, each of the fasteners 9 has a reception member 90 and a bolt 91. The reception member 90 has a tubular portion 900 in which a threaded hole 901 is defined. The bolt 91 is threadedly connected to the threaded hole 901 of the tubular portion 900.

When assembling the pet cage, the two parallel insertion ends 310 extend through the two holes 301 of one of the two sidewalls of the base 30, and the two springs 32 are respectively mounted to the two insertion ends 310. The two pins 33 respectively extend through the two pm holes 311 of the two insertion ends 310. Each pin 33 has one end inserted into the sliding slot 300 corresponding thereto. Each of the springs 32 is biased between the sidewall of the base 30 and the pin 33 corresponding thereto. The distal end of each of the insertion ends 310 extends through the hole 301 from the other sidewalls of the base 30. The cover 34 is then connected to the base 30 by engaging the two hooks 340 of the cover 34 with the engaging slots 302 of the base 30. The grip 313 is located outside of the base 30 which is fixed to the door 21. The receiving base 35 is fixed to the door frame 2. The two insertion ends 310 of the bar 31 respectively extend through the two apertures 350 of the receiving base 35.

The left board 6 and the right board 7 are respectively on two sides of the top board 4 and the bottom board 5. The bolts 64, 74 extend through the holes 63, 73 of the left and right boards 6, 7, and are fixed to the threaded holes 42, of the top board 4 and the bottom board 5. The back board 8 is connected to the rear ends of the top board 4, the bottom board 5, the left board 6 and the right board 7. The bolts 81 extend through the holes 80 of the back board 8 and are threadedly connected to the threaded holes 42, 52, 62, 72 of the top board 4, the bottom board 5, the left board 6 and the right board 7. The door frame 2 is connected to the front and of the top board 4, the bottom board 5, the left board 6 and the right board 7. The tubular portions 900 of the reception members 90 of the fasteners 9 extend through the holes 41, 51, 61, 71 of the walls 40, 50, 60, 70 of the top board 4, the bottom board 5, the left board 6 and the right board 7, and the holes 20 of the door frame 2. The bolts 91 then extend through the holes 20 and are threadedly connected to the threaded holes 901 of the reception members 90. Therefore, the door frame 20 is connected to the top board 4, the bottom board 5, the left board 6 and the right board 7.

When the door 21 is to be opened, the owner holds the grip 313 and pulls the bar 31 outward as shown in FIGS. 12, 13, the insertion ends 310 compress the springs 32 and the pins 33 are moved within the sliding slots 300, so that the insertion ends 310 are removed from the apertures 350 of the receiving base 35, and the door 21 can be opened. The bar 31 does not drop from the base 30. When releasing; the grip 313, the springs 32 push the two insertion ends 310 back to their initial positions. In other words, the door 21 can be opened by one hand.

When closing the door 21, the owner pivots the door 21 toward the door frame 2, the two oblique faces 312 of the insertion ends 310 are moved along the tapered plate 351, so that the insertion ends 310 are pushed inward to compress the springs 32 until the two insertion ends 310 are moved to be in alignment with the apertures 350 of the receiving base 35, the springs 32 push the insertion ends 310 are inserted into the apertures 350 again to lock the door 21 as shown in FIG. 14. The door 21 can be closed by one hand.

As shown in FIG. 15, all of the parts of the pet cage can be dis-assembled by removing he fasteners 9 and the bolts 64, 74, 81, Therefore, all of the parts can be overlapped piece by piece in order to save the space.

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