(1) Field of the Invention
The present invention relates to a foldable stand including two upper parts and two lower parts, and the two upper parts can be pivotable relative to the lower parts.
(2) Description of the Prior Art
A conventional stand 1 for support a cutting machine is shown in
The present invention intends to provide a foldable stand which includes two upper parts and two lower parts, the two lower parts can be pivotable toward each other and the two upper parts can be pivotably relative to the two lower parts. The foldable stand improves the shortcomings of the conventional stand.
The present invention relates to a foldable stand which includes a first lower part having two separated upper ends which are pivotably connected to two separated upper ends of a second lower part by two plates which are pivotably connected between the upper ends of the first lower part and the second lower part. The two upper ends of the second lower part are located at insides of the two upper ends of the first lower part. Each plate is an inverted V-shaped plate and has a first stop and a second stop extending from two sides thereof.
A first upper part has two separated lower ends and two first lugs extend from the two lower ends of the first upper part. A bar is pivotably connected between the two first lugs. The two lower ends of the first upper part are located at insides of the two upper ends of the second lower part. Two first protrusions extend from the two lower ends of the first upper part respectively. A second upper part has two separated lower ends and two second lugs extend from the two lower ends of the second upper part. The two second lugs are pivotably connected to two outsides of the two upper ends of the first lower part. Two second protrusions extend from the two lower ends of the second upper part respectively.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
Each plate 15 is an inverted V-shaped plate and has a first stop 151 and a second stop 152 extending from two sides thereof.
A first upper part 13 has two upper ends with a bar connected therebetween, and two separated lower ends. Two first lugs 131 extend from the two lower ends of the first upper part 113. A bar 16 is pivotably connected between the two first lugs 131. The two lower ends of the first upper part 13 are located at insides of the two upper ends of the second lower part 12. Two first protrusions 132 extend from the two lower ends of the first upper part 13 respectively.
A second upper part 14 has two upper ends with a bar connected therebetween, and two separated lower ends. Two second lugs 141 extend from the two lower ends of the second upper part 14. The two second lugs 141 are pivotably connected to two outsides of the two upper ends of the first lower part 11. Two second protrusions 142 extend from the two lower ends of the second upper part 14 respectively. Two bolts 17 each extend through the second lugs 141, the first lower part 11, the plate 15, the second lower part 12, the first upper part 13 and one of two ends of the bar 16.
