Description

1 - The invention relates to a working table for supporting workplaces on

various working machines.

Various kinds of typical working tables have been 05 developed for supporting workpieces on various working machines, and comprise a table movable up and down, and movable forwardly or rearwardly; or movable laterally, for moving the workpieces relative to the working machines. However, the typical working tables normally 10 include a complicated configuration that may not be easily manufactured and assembled, and that may not be stably supported to move relative to the working machines. It is accordingly an object of the present 15 invention to provide a working table having a stable and simplified structure for stably supporting the workplaces to move relative to the working machines, and for allowing the working table to be easily manufactured and assembled.

20 SUMMARY OF THE INVENTION

According to the present invention there is provided a working table comprising: a) a housing including a chamber, and at least one channel and a middle groove formed therein and 25 communicating with the chamber thereof, by a board slidably received in the chamber of the housing,

- 2 - cl a casing secured to the board and moved in concert with the board, d) a post slidably engaged through the groove of the housing, and slidably engaged through the casing, 05 e) a spindle rotatably secured in the housing, and slidably engaged through the casing, for guiding the casing to move relative to the housing, and including means for moving the post up and down relative to the board and the housing, 10 f) at least one rod slidably engaged through the channel of the housing, and engaged through the board, and g) a table disposed on top of the post and the rod, and to be moved up and down by the post and the 15 moving means of the spindle.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-5, a working table comprises

- 3 a housing 2 including a middle groove 20, two side channels 21, 22, and one or more pairs of slots 23, 24 formed in the upper portion, and preferably parallel to each other, and communicating with a chamber 29 of the 05 housing 2. A number of rollers 25, 26 (FIG. 5) are rotatably secured in the sides of the housing 2 with such as shafts 28 (FIGS. 1, 2.

A board 3 is slidably received in the chamber 29 of the housing 2, and has two sides engaged with the 10 rollers 25, 26, for allowing the board 3 to be moved laterally, or to be moved forwardly and rearwardly relative to the housing 2, best shown in FIGS. 3, 5.

The board 3 includes two side orifices 30 for aligning with the side channels 21, 22 of the housing 2.

15 A casing 32 is secured to the bottom of the board 3 with fasteners 31 and moved in concert with the board 3. The fasteners 31 may optionally or selectively be slidably engaged in the slots 23, 24 of the housing 2, for further or additionally or selectively guiding the 20 board 3 and the casing 32 to move along the slots 23, 24 of the housing 2. A post 6 is slidably engaged through the middle groove 20 of the housing 2, and engaged through the board 3 and engaged into and through the casing 32 IFIG. 4).

25 A spindle 7 is rotatably secured in the housing 2, and slidably engaged through the casing 32, in order to further stably guide the casing 32 and the board 3 to

- 4 move relative to the housing 2. The spindle 7 includes one or more longitudinal guiding members 70, such as keys 70 (FIGS. 1, 3-5), or flat surfaces 73 (FIG. 7), and a worm 71 is slidably engaged onto the spindle 7 05 and includes corresponding recesses or flat surfaces for engaging with the keys 70 or flat surfaces 73, and for preventing the worm 71 from rotating relative to the spindle 7.

A gear 322 is rotatably secured in the casing 32, 10 and engaged with the worm 71 (FIGS. 3, 4). The post 6 includes a rack 60 formed thereon (FIG. 3) and engaged with the gear 322, such that the post 6 may be moved up and down by the gear 322 when the worm 71 and the spindle 7 is rotated relative to the housing 2. A 15 handle 72 may be secured to the spindle 7, for rotating the spindle 7 and the worm 71 to rotate the gear 322 and to move the post 6 up and down relative to the housing 2 and the casing 32.

Two ducts 34, 36 are engaged through the orifices 20 30 of the board 3, and slidably engaged through the side channels 21, 22 of the housing 2, and secured to the board 3 with such as collars 33, 35, and fasteners.

Two rods 5, 4 are slidably engaged through the ducts 34, 36 respectively, and having upper ends secured to 25 bottom of a table 8 with such as brackets 51, 41, for allowing the rods 4, 5 to be moved up and down with the table 8.

- 5 The upper end of the post 6 is engaged with the table 8 or secured to the table 8, such that the table 8 may be moved up and down by the post 6 and the gear 322 (FIG. 4) when the worm 71 and the spindle 7 are 05 rotated by the handle 72. Two springs 43 ? 53 are engaged on the rods 4, 5 and engaged with the ducts 36, 34 respectively, for biasing the rods 4, 5 and thus the table S downwardly toward the housing 2 (FIG. 4).

In operation, the board 3 may be guided to 10 smoothly move relative to the housing 2 by the rollers 25, 26, and the casing 32 may be slided along the spindle 7, and the post 6 may be elided along the middle groove 20 of the housing 2, and the ducts 34, 36 and the rods 5, 4 may be slided along the side channels 15 22, 21 of the housing 2, such that the table 8 may also be guided to smoothly move relative to the housing 2.

The table 8 may be moved up and down by the post 6 and the gear 322, and the worm 71 of the spindle 7, and the handle 72. In addition, the springs 43, 53 may also 20 apply a spring biasing force against the rods 4, 5 and the table 8, for stably supporting the table 8 above the housing 2.

As shown in FIG. 6, the housing 2 may be disposed on a base 9 and disposed beside various working 25 machines 91, such as the milling machine, grinding machine or the like, for supporting the workplaces to the working machines 91.
