Description

Reset rail device

The present invention relates to a rail assembly, and more particularly to a reset rail assembly having an automatic reset function.

In life, there are various kinds of mechanisms that use slide rails, such as drawers, cabinets, or any products that use sliding motion. In the post-modern society where the activity space is gradually narrowed, such products are more valued. Slide rail mechanisms are quite common in today's applications, and can be designed and adjusted for various applications in order to achieve additional functions beyond reciprocation, such as automatic positioning or resetting.

The conventional reset rail technology mostly uses an axially disposed spring to be stretched and clamped to a fixed object to achieve the positioning function, and is reset by the spring contraction force when the fixed object is released. However, in the long-term use state, the spring continues to maintain the tension state, which tends to cause the spring to quickly fatigue and lose the reset function. In addition, the conventional reset slide rail technology has a complicated mechanical structure and a high failure rate, and the cost is very high, and has serious shortcomings such as short life and difficulty in maintenance.

In view of the above, the present invention proposes a reset rail device that can perform the conventional technical functions by using a simple structure and a stable operation to eliminate the disadvantages of the aforementioned reset rail technology.

It is an object of the present invention to provide a reset slide rail device which is provided with a spring that does not move in the same axial direction and pushes the slide member, and uses the spring to have a tendency to restore the original shape, so that the push slide member is indirectly driven by the spring to achieve automatic reset.
