Adjustable table with an assistant device
View Patent ↗An adjustable table includes a table board, a first foot, a second foot, an air pressure bar and an assistant device. The first foot crossly and pivotally connects with the second foot, wherein one end of the first foot pivotally connects with a first fastener on the bottom side of the table board, and one end of the second foot pivotally connects with a pivot joint. The assistant device is fixed between the first fastener and a second fastener, wherein one end of the air pressure bar is fixed on the second fastener while the other end fixed on the assistant device. Therefore, when the air pressure bar is operated, smooth sliding of the air pressure bar is provided, whereby the structural strength of the table is reinforced.
1. An adjustable table with an assistant device comprising:
a table board, with a first fastener and a second fastener on the bottom side thereof;
a first foot with one end pivotally connected to the first fastener;
a second foot pivotally connected with the first foot;
a pivot joint pivotally connected to one end of the second foot;
an air pressure bar installed between the first fastener and the second fastener, possessing a stretching rod and a rod body, wherein the bottom end of the stretching rod is fixed on the second fastener;
a lever, provided with a tab part, and pivotally connected to one end of the second fastener, whereby the tab part of the lever interacts with the stretching rod of the air pressure bar in order to make the air pressure bar stretch or shorten;
an assistant device, possessing at least one sliding stick installed between the first fastener and the second fastener, one sliding member slidingly disposed around the sliding stick, and a combining piece installed on one end of the sliding member and fixed with one end of the rod body of the air pressure bar;
wherein the sliding member together with the rod body of the air pressure bar displace corresponding to the sliding stick when the air pressure bar is operated, in order to change the angle included by the first foot and the second foot and further adjust height of the table.
2. An adjustable table with an assistant device of claim 1 , wherein the assistant device comprises another sliding stick and another sliding member slidingly disposed on the sliding stick, and the combining piece is positioned between the two sliding members.
3. An adjustable table with an assistant device of claim 2 , wherein two ends of the two sliding sticks are screwed on the first fastener and the second fastener, respectively.
4. An adjustable table with an assistant device of claim 2 , wherein the air pressure bar is installed between the two sliding members.
5. An adjustable table with an assistant device of claim 1 , wherein the first fastener has two lateral hole plates for one end of the first foot to be pivotally connected to.
6. An adjustable table with an assistant device of claim 1 , wherein several wheels are installed on bottom ends of the first foot and the second foot, respectively.
