Description

[Detailed description of the invention]       [0001]     [Technical field to which the invention belongs]   The present invention relates to a table height adjusting mechanism, and is particularly applied to steel pipe furniture. The height of the table can be adjusted conveniently and quickly, and the total volume of the folded table Is extremely small, which makes it easier to transport and store. .       [0002]     [Prior art]   At present, commercially available table height adjustment mechanisms mainly use pneumatic cylinders. I have.       [0003]     [Problems to be solved by the invention]   It has the following disadvantages.   (B) Since the cost of the pneumatic cylinder is high, the price of the entire product also increases, The field loses its competitiveness.       [0004]   (B) The pneumatic cylinder has a predetermined service life, and the pneumatic cylinder is damaged. Buying and replacing expensive pneumatic cylinders is expensive in terms of cost Thus, the entire table must be discarded.   (C) The table using the pneumatic cylinder is folded for the pneumatic cylinder. There is a predetermined height that is not low even after folding, so the volume of the package is large and transportation costs are high. And the final price will be higher, losing market competitiveness.       [0005]   The main purpose of the present invention is to adjust the height of the table conveniently and quickly, The lowest height in cases where packaging volume is minimized and transportation costs are reduced. Provided is a table height adjusting mechanism that can be reduced.       [0006]     [Means for Solving the Problems]   Claim 1 of the present invention made to achieve the above object is mainly a cross pivot portion. The left foot and the right foot pivoted by are used as table supports, and the top end of the left foot is It is fixed to one side of the bottom of the table board by the pivoted table board connector. The upper ends of the parallel pipes of the feet are pivotally connected with the corresponding fitting pipes, and inside each fitting pipe Are separately provided with inner rods, and the tip of the inner rod is located at the bottom of the table plate. In the table height adjustment mechanism connected to the table board connector fixed to the other side, The upper part of each fitting pipe is fixed to one end of a coil spring. The end is fixed to the end of the inner rod and is located between the tips of the two fitting pipes. The inner rod is provided with a stopper, and each inner rod has a plurality of Is provided, and a control rod is installed inside any one of the inner rods. When the pad is pulled, the stopper is raised to a predetermined height and once separated from the engagement groove. By doing so, the height of the table can be adjusted or folded, and When the adjustment is completed, the control rod is released and the stopper is A table height adjustment mechanism characterized by being fitted into the corresponding engagement groove again The gist is that there is.       [0007]     [Embodiment of the invention]   First, a description will be given with reference to FIGS. Table height according to one embodiment of the present invention According to the adjusting mechanism of the left, mainly the left foot 2 and the right foot pivoted by the cross pivot point A 3 is used as a support for the table 1 and the top end of the left foot 2 is connected to a pivoted table board. Is fixed to one side of the bottom portion of the table board 4 by a child 21 and a parallel pipe of the right foot 3 The upper end of 31 is pivotally connected to the corresponding fitting pipe 5, and the inside of each fitting pipe 5 is separately An inner rod 6 is installed at the bottom of the table plate 4. In the table height adjustment mechanism connected to the table plate connector 61 fixed to the other side The upper part of each fitting pipe 5 is fixed to one end of a coil spring 7, and the coil The other end of the spring 7 is fixed to the end of the inner rod 6 and the two fitting pipes 5 A stopper 8 is provided above the tip, and the inner rods 6 are equidistant. A plurality of engagement grooves 62 are provided, and a control lock is provided inside any one of the inner rods 6. When the control rod 9 is pulled (in the direction of the arrow shown in FIG. 5), As shown in FIG. 5, the stopper 9 is raised to a predetermined height and It is possible to adjust the height of the table 1 or fold it by detaching it at once. When the height adjustment is completed, as shown in FIG. Is released, and the stopper 8 is again fitted into the corresponding engagement groove 62 by the spring 81. Thus, the height of the table can be adjusted conveniently and quickly.       [0008]   If you want to fold the table 1 in the same way (the direction of the arrow shown in the figure) F) The control rod 9 is pulled, and as shown in FIG. Once lifted and disengaged from the engagement groove 62, as shown in FIGS. The bull 1 is folded down to its lowest height, the control rod 9 is released and the stop -8 is again fitted into the corresponding engagement groove 62 by the spring 81. This allows Cable volume can be reduced, and transportation costs can be reduced.       [0009]   This invention has the following effects.   (B) Steel tube furniture (for example, office tables, personal computer tables, and drafting tables) Table, etc.) to adjust the table height conveniently and quickly.   (B) The entire volume of the folded table is extremely small, making transportation and storage convenient. Be profitable.
