A portable expandable device with a contracting mechanism which allows for many forms of recreational products and structures to be expanded, reinforced in the expanded shape, and then contracted easily to regain its portable form. The expansion means is exercised by the use of at least one of the following, resiliently extending, unfolding, inflating, as to become an expanding form which can then be easily retracted to the redeployed form. The retraction mechanism reverses the expansion process utilizing a mechanism which sequentially exerts the forces needed in the proper locations in order to ensure proper contraction. Disclosed embodiments utilized supplemental structural reinforcement of the expanded form through the use of joints, releasable interlocks, latching mechanisms, air bladders, to ensure the form is stable and usable. The objective being a stable structure with a rapid and easy deployment and a supplemental retraction means as to be easily transportable.

A vehicle rear window cover comprising: a cover portion; a first strap assembly, which comprises one or more strap loops; a second strap assembly, which comprises one or more strap loop; two hooks that are configured to engage with said strap assemblies and a vehicle, such that the cover portion substantially covers the rear window of a vehicle. Because the hooks may be moved from loop to loop, the cover is adjustable. The cover may also comprise support members that prevent bulging, flapping, or puckering of the cover portion.

An elastic mosquito net for a car front side window is revealed. The elastic mosquito net made of elastic mesh fabric is installed on a window frame of a front door of a car. A mounting hole is disposed on an outer fabric surface of the elastic mosquito net and corresponding to a rear-view mirror for allowing a neck portion of the rear-view mirror to be inserted through. The mounting hole is provided with a drawstring by which users can operate to make the mounting hole wrap and fit to the neck portion closely for preventing mosquitoes and insects from passing through a gap between the mounting hole and the neck portion and the open front side window and then entering the car. The drawstring can be replaced by a separable connecting member which allows users to adjust a length/area thereof being connected for tight and close fit.

A car window and door guard has an upper or window portion configured to be mounted over the window frame surrounding the window of a car door, and a lower or door portion or cover configured to be lie over the door panel. The window portion has a front panel and a rear panel to form a sleeve. The window portion is generally see-through or transparent. The door includes an upper strip or section and a series of window tabs. Each window tab has a generally flat or planar portion extending from an elongated upper channel portion. The channel portion captures the door window slot or surround to prevent the window tab from being moved upward during the raising of the window. The door portion also has a lower section extending downwardly from the upper section that drapes over the car's door panel to protect the door panel.
