Table with angle adjustable top plate {TABLE WITH AN ANGLE-ADJUSTABLE TABLE TOP}

[See before and after related application]

This application claims the priority of Taiwan application 097213415, filed July 29, 2008.

The present invention relates to a table having an angle-adjustable top plate, and more particularly to a table having an angle adjustment mechanism that enables adjustment of the inclination angle of the top plate of the table.

A table having an angle adjustable top plate allows for adjustment of the tilt angle of the top plate via an angle adjusting mechanism. As shown in FIGS. 1 and 2, this table generally comprises a support body 6, a top plate 7, an angle adjustment mechanism 8, and a pivot mechanism 9.

The support body 6 has an end side 600 and an opposing side 601 opposite the end side 600.

The top plate 7 has an end side 700 which is pivoted on the end side 600 of the support body 6 via a pivot mechanism 9, and an opposing side 701 opposite the end side 700 of the top plate 7. Has The top plate 7 is movable to approach or move away from the opposite side 601 of the support body 6 such that the top plate 7 on the support body 6 is at an angle of inclination of the top plate 7 with respect to the support body 6. It can be rotated to adjust.

The angle adjustment mechanism 8 has two ends 800, 801, one of which is connected to the top plate 7 and the other to the support body 6. The angle adjustment mechanism 8 includes a slidable telescopic structure that allows the two ends 800, 801 to move along or along each other's travel path between the ends 800, 801; Multiple locking positions along a travel path; And a ratchet mechanism 806 that acts as a locking mechanism to releasably lock the telescopic structure 803 in one of the locking positions. The top plate 7 is also supported by an angle adjustment mechanism 8 which is rotated by the movement of the two ends 800, 801 and locked in one of the locking positions so that the top plate 7 with respect to the support body 6. You can adjust the angle of inclination.

By providing the ratchet mechanism 806, the two ends 800, 801 are limited to be separated from each other by sliding of the telescopic structure only during the lowering operation.

In other words, if an increase in the inclination angle is desired, the opposite side 701 of the upper plate 7 is moved away from the opposite side 601 of the support body 1 only by rotating the top plate 7 to have the desired inclination angle by the upward movement. It is necessary to make the ascending operation easy by moving forklift. This is because the two ends 800, 801 start from each other by the upward motion, and this motion is not limited by the ratchet mechanism 806. Thereafter, even if the top plate 7 falls by its own weight and pushes the two ends 800 and 801 to move toward each other, the top plate 7 can be supported by the angle adjusting mechanism 8, which is This is because the ends 800, 801 cannot move toward each other due to the constraints imposed by the ratchet mechanism 806.

In addition, if a reduction of the inclination angle is desired, this operation is not performed by directly moving the opposing side 701 of the upper plate 7 toward the opposing side 601 of the support body 1, and instead the lowering operation is performed as follows. Will be performed together. First, the top plate 7 is rotated upward to the highest position by the lifting operation to release the ratchet mechanism 806. Then, the upper plate 7 is rotated downward to have an inclination angle slightly lower than the desired inclination angle, or rotated downward to the lowest position. Finally, the upper plate 7 is rotated to have a desired inclination angle by the raising operation.

In this conventional table, the lowering of the upper plate 7 is limited by the ratchet mechanism 806, unless the lowering operation is performed, so that the upper plate 7 can be safely supported by the angle adjustment mechanism 8. have.

However, during the second phase of the lowering operation, the upper plate 7 can be unexpectedly lowered by its own weight and quickly approach the support body 6 cannot be completely prevented. Once this happens, there is a risk of injury to the user.

It is therefore an object of the present invention to provide a table having an angle adjustable top plate that can overcome the above-mentioned disadvantages associated with the prior art.

Thus, the table having an angle-adjustable top plate of the present invention, the support body having an end side and the opposite side opposite the end side; A top plate having an end side and an opposing side, the end side being pivoted on the end side of the support body, the opposing side opposing the end side of the top plate and moving toward or away from the opposing side of the support body Possibly, the top plate on the support body can be rotated to adjust the inclination angle of the top plate relative to the support body; And an angle adjustment mechanism having two ends, one of which is connected to the top plate, the other to the support body, wherein the angle adjustment mechanism is such that the two ends face each other along the path of movement or to each other. Configured to be movable away from, and having a plurality of locking positions along the travel path such that the angle adjustment mechanism can be locked in one of the locking positions, the top plate being rotated by movement of the two ends and Supported by the angle adjustment mechanism locked in one of the locking positions to adjust the inclination angle of the top plate relative to the support body; . The angle adjusting mechanism has the two ends and is configured to have a slidable stretchable structure between the ends such that the angular adjustment member can slide the ends toward or away from each other, and the stretchable material And a damper that slows the sliding speed of the structure to prevent the top plate from quickly approaching the support body when the stretchable material slides.

In order to lock the telescopic structure of the angle adjustment mechanism in one of the locking positions, the angle adjustment mechanism is typically configured to have a locking mechanism. The locking mechanism may be a conventional ratchet mechanism 806 or any other releasable locking mechanism. However, for ease of comparison with a conventional table, the locking mechanism is implemented using the ratchet mechanism in an embodiment of the present invention.
