Benefits of technology

The solution ensures the slide out section extends and retracts without skewing, maintaining a tight seal and minimizing noise, while optimizing space utilization and operational efficiency.

Problems solved by technology

These prior art constructions are adequate for many applications, however, they can be inefficient and are noisy.
This unbalanced condition can cause the slide out section to skew and become jammed.

Embodiment Construction

[0031] The present invention provides a slide out assembly attached to a known trailer or recreational vehicle which provides distinct advantages over the prior art as will be described and appreciated hereafter. In the preferred embodiment, the trailer or recreational vehicle (generally referred to as the vehicle) is equipped with a slide out section used to provide additional interior room space. However, it should be understood that the invention can also apply to expandable sections or compartments provided on other vehicles for use in construction, military, medical, education, mobile broadcast and other applications, to expand the inside volume of the vehicle.

[0032]FIG. 1 illustrates the vehicle body 10 having mounted thereon an expandable, telescopic slide out room section 12 incorporating the present invention in its fully retracted position. FIG. 2 is a similar view with the slide out section 12 fully extended.

[0033] As shown in FIGS. 3-12, the vehicle 10 includes exterio...

Abstract

A slide out actuating mechanism for selectively extending and retracting a slidable section of a slide out assembly fixed to a vehicle body includes at least two double acting fluid actuated actuators. Each actuator has a cylinder and an extendible ram. Each cylinder is fixed relative to one of the vehicle body and the slidable section, and each ram is fixed relative to the other of the vehicle body and the slidable section. At least one flow divider having at least two fluid ports directs fluid to and from the cylinders. One of the fluid ports is in fluid communication with one of the cylinders and the other of the fluid ports being in fluid communication with the other of the cylinders, wherein the flow divider maintains the flow of fluid flowing through the ports at substantially equal flow rates to synchronize movement of the rams when moving the rams relative to the cylinders.
