Reinforcement device of folding tent
A reinforcement device of tent poles to strengthen the two opposite branch frames that requires reinforcement of tent poles is disclosed. The device includes two connection sections and two connection rods, whereas each connection section is set up with two pivots perpendicular to or in wide angle to each other, and connects with tent poles and a head end of the connection rod respectively. And the two connection rod arranged between two pivots and linked together at end by a pivot with a position member which make the two connection rods lock tightly when stretch straight to possess reinforcing force. Furthermore, apply the reinforcement device on the two requiring reinforcement opposite branch frames of tent poles. The reinforce device can stretch straight and fold synchronously with the opening and folding of the tent poles to strengthen the solidity of the tent poles after being extended while with no influence on opening and folding of the tent poles.
The present invention relates to a reinforcement device of a folding tent, especially refer to the function of reinforcing two opposite branch frames of the tent poles and stretching straight as well as unfolding between the two branch frames in concurrent with the expanding and folding of the tent poles without any influence.
Current outdoor life popularizes the usage of folding tents whose frames can be extended quickly and supported by landing rods, and then covered with main tent and attached tent to shield from raining, sun burn, and windy condition. Traditional folding tents show various kinds of design, such as disclosed in U.S. Pat. No. 5,275,188, U.S. Pat. No. 5,421,356, U.S. Pat. No. 5,490,533, U.S. Pat. No. 5,638,853, U.S. Pat. No. 5,701,923, U.S. Pat. No. 5,511,572, U.S. Pat. No. 5,133,378, etc. The shapes judging from the top view of the tent are categorized into rectangle type ‘Cross-shaped’ X-shaped, etc. However, the designation of these tents were mostly dedicated in its shape, size, or folding structure, etc, and mostly neglects the structure of tents solidity and setup after extending. Therefore in practical use, the frame weakness is raised or even influenced the opening and folding frame structure of the truss bar and pole of tents.
SUMMARY OF THE INVENTIONIt is therefore a primary object of the present invention to provide a reinforcement device of folding tents, which comprises two connection sections and two connection rods; the two connection sections connected with the two opposite requiring reinforcement branch frames, whereas each individual connection section contains two pivots perpendicular to or in wide angle (an obtuse angle) to each other; and then one of the pivots connected with the branch frame of the tent poles, the other connected with the head end of connection rod. The two connection rods set up within the two connection sections, and link its two ends together with a pivot with a position member nearby which make the two rods extend straight firmly locked and yield a function of reinforcement; therefore the reinforcement device could be opened and folded concurrently with the extending and folding frame of tent poles to add the solidity of tent.
It is another object of the present invention to provide an option of reinforcement device, and with a position member at the end of each connection rod near pivot. The mechanic of position member could apply the application opinion of elastic pin, V button, Velcro belt, Buckle belt, casing ring, or U-shaped ring to lock the two connection rods tightly when the two rods stretch straight concurrently with the extending frame of tent poles and truss bar.
BRIEF DESCRIPTION OF THE DRAWINGS
First of all, referring from
Furthermore, the two connection rods 20 were set between two pivots 10 and linked by a pivot 23 at tail end 22 with a position member 24 as shown in
Further referring from
The position member 24 arranged at the joint of respective end of the two connection rods 20 mainly fixes the two rods 20 when stretch straight with the expanding of the two opposite branch frames 31, 32 to yield an enough supporting force. The structure of the position member 24 is optional, it could be elastic pin type shown as per

The present invention of reinforcement device 1 could be installed on the poles of various kinds of collapsible tents, such as the rectangle-type tent poles 3 in
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein.
Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
Claims
1. A reinforcement device of a folding tent disposed on tent poles comprising two connection sections, two connection rods, and a position member, wherein:
- the connection section connected with two opposite branch frames requiring being reinforcement of tent poles and having two pivots perpendicular to or crossed in an wide angle to each other; one pivot is connected with one of the two opposite branch frames of the tent poles while the other pivot is connected with a head end of the connection rod;
- the connection rods disposed between two connection sections and linking with each other at respective tail end by a pivot, and depended on the pivot, the two rods could be folded into a cross type, or stretched into a straight type, and a position member is set up at the tail end thereof;
- the position member set up at the cross end of the two connection rods were used to fix the two connection rods firmly when the two rods are stretched in parallel;
- thereby the reinforce device is able to stretch or fold synchronously with expanding and folding of the tent poles, and supporting the two branch frames of tent poles after being stretched straight.
2. The reinforce device of a folding tent of claim 1, wherein the connection section having two L-shaped angle irons which is connected to each other by one side to form into one unit as a pivot, while another pivot is disposed on another side of the angle iron for connecting with the head end of the connection rod and the two pivots are perpendicular to each other.
3. The reinforcement device of a folding tent of claim 1, wherein the connection section is formed by a wide U-shaped angle iron whose two sides are open in a wide angle, and the two pivots are arranged respectively on two sides of the angle iron and cross with each other in wide angle.
4. The reinforce device of a folding tent of claim 1, wherein the position member is an elastic pin that is disposed on one of the connection rods and a corresponding hole is arranged at the other connection rod so that the elastic pin is mounted into the corresponding hole for positioning the connection rods in straight status when the two connection rods expend into straight and parallel status.
5. The reinforcement device of a folding tent of claim 1, wherein the position member is a buckle belt that is disposed on either connection rod or both connection rods, and by binding the buckle belt around the tail end of the two connection rods, the two connection rods are positioned in straight status for supporting when the two connection rods expend into parallel and straight status.
