Description

Improved clevis assembly and fly adapter assembly and frame for folding umbrella tent

Umbrella tents have existed for a long time and have been used. Folding umbrella tents have been around since the beginning of the century and generally include a folding frame that supports the tent's fabric or other flexible fabric materials when the tent is built. Since such tents are built and folded in the same way as umbrellas, the term "umbrella" tent is widely used in the commercial field. One example of a modern umbrella tent is shown in US Pat. No. 4,945,936. Other examples of folding umbrella tents are shown in US Pat. Nos. 4,033,366, 3,929,146, 3,794,054, 3,000,386, 1,666,757, 1,124,420 and 1,079,757. In general, an umbrella tent is composed of a folding frame having a plurality of legs pivotally joined to an upper end by a clevis assembly having an upper clevis member and a lower clevis member. Each leg has a radial support member, which faces inwardly each support member attached to the upper end of the leg and inwardly coupled to the lower clevis member. The upper and lower clevis members are designed to engage when the tent is erected. The lower clevis includes a central upwardly projecting pin, post, or rod, as shown in US Pat. No. 4,945,936, while the upper clevis member includes a central opening recess facing down. Alternatively, the lower clevis member may include a central opening recess and the upper clevis member may include a central projecting pin, post or rod, as shown in US Pat. No. 3,929,146. One drawback of such a tent arises on the locking device side, which allows the lower and upper clevis members to engage when the tent is built. This disadvantage is due in part to the torque and torsional forces applied to the clevis member when the tent is built. Therefore, one object of the present invention is to improve the locking device of a folding umbrella tent.

Folding tents have been constructed by framing the outside of the tent fabric (see, for example, US Pat. No. 4,945,936) or by framing the interior of the tent (see, eg, US Pat. No. 3,929,146). Any type of tent may be provided with a fly cover that creates an air gap between the tent fabric. (Fly covers are sometimes referred to herein as fly sheets or simply plies.) These air layers can act as waterproof and insulating films for the user. Although the fly cover has been previously installed in a folding tent with an outer frame, it is required to improve the fly cover attachment device for the outer frame folding tent in order to quickly install the tent and the fly cover. In addition, folding tents, which usually have an inner frame, have no technical design to accommodate the addition of a fly cover when needed. It is therefore an object of the present invention to provide a fly adapter assembly and a modified clevis assembly for arbitrarily attaching the fly adapter assembly to a clevis member adapted to help secure the fly cover to the collapsible tent.

The present invention relates to an improved collapsible umbrella tent, and more particularly to an improved clevis assembly having an improved locking device. The improved clevis assembly also includes a reinforcing element for adding a separate fly adapter that allows the fly sheet to be added to the tent.
