Description

Collapsible tent with central lock and reinforced pole

Technical Field

The utility model relates to an outdoor product specifically relates to a collapsible tent with central lock and anchor strut.

Background

Collapsible tents that can be locked in the deployed position are very popular in modern society. Generally, each foldable tent comprises a foldable tent frame consisting of a top frame and four or more support legs for supporting the top frame and provided with a locking structure on each support leg, respectively, and a foldable tent fabric covering the top frame and for shading, protecting or preventing wind. Currently, the locking structure is generally a latch, and the unfolded state of the collapsible shelter is locked by individually locking each of the support legs. However, this approach has the following drawbacks:

during the unfolding or folding of the foldable tent, when unfolding or folding the foldable tent, a user needs to perform a locking operation or an unlocking operation on the locking mechanism of each support leg one by one. The operation is complicated, and abnormal operation of functional defects or forced unlocking may occur. Also, the unfolding or folding of the collapsible shelter requires the cooperation of many people so that the collapsible shelter can be erected. In addition, the stress points of the plurality of support legs are not uniformly stressed during the unfolding and erection of the collapsible shelter, so that it is difficult to support the collapsible shelter at an optimal point, and thus the supporting effect of the collapsible shelter is affected. The damage of the collapsible tent occurs mainly on the support legs of the collapsible tent because it is required to fix the position of the slider after the collapsible tent is unfolded and to form a hole in the support leg at the fixed position of the slider so as to insert the latch. The holes in the support legs weaken the support strength of the support legs, and the support legs are often damaged at the fixed position of the slider, thus shortening the service life of the collapsible shelter.

It is also noted that prior art collapsible tents may be unstable if exposed to certain specific conditions. For example, fig. 31 shows a prior art tent 895 covered in fabric. Wind blows on the sides of the tent 895. Unfortunately, the tent 895 has no way to resist such external forces, and thus its sides deform due to wind forces.

What is needed is a collapsible tent having better locking mechanisms and structural reinforcement that better resists shape deformation.

Fig. 5 shows the collapsible tent 750 in an unlocked and collapsed position, similar to that shown in fig. 3. In fig. 3, gravity is applied to the first inclined ceiling pipe 692 in a downward pressing manner. The user has not pressed the central bottom cover 602 upward.

In fig. 6, the user has begun to press the bottom cover 602 upward. The angled top tube 692 has begun to pivot outward from the center. The bottom cover link 693 is rotatably connected to the bottom cover 602 at a bottom cover pivot 603 and the bottom cover link 693 is rotatably connected to the angled top tube 692 at a top tube pivot 604. In fig. 6, the pivot 603 is lower than the pivot 604. Thus, the user must continue to press the bottom cover 602 upward to overcome the weight of the angled top tube 692.

In fig. 7, the user further presses the bottom cover 602 upward. The inclined top tube 692 further rotates outward. In fig. 7, the pivot 603 is still lower than the pivot 604. Thus, the user must still continue to press the bottom cover 602 upward to overcome the weight of the angled top tube 692.

In fig. 8, the user further presses the bottom cover 602 upward. The pivot 603 is now higher than the pivot 604. Once the pivot 603 becomes higher than the pivot 604, the weight of the angled top tube 692 will cause the bottom cover 602 to move upward such that the user no longer needs to press the bottom cover 602 upward. In fig. 8, the top tube 692 has begun to rotate inward and the bottom cap 602 is forced upward near the stop bar 700. The user may now stop pressing the central bottom cover 602 upward. The downward force provided by the angled top tube 692 will move the bottom cap 602 upward until stopped by the stop rod 700.

In fig. 9, the downward force provided by the angled top tube 692 has moved the bottom cap 602 upward such that it has been stopped by the stop bar 700. The pivot 603 is higher than the pivot 604. The central locking mechanism 720 is now in a self-locking position. It should be noted that the self-locking position is reached after the bottom lid pivot 603 becomes higher than the top tube pivot 604. After this, the user may stop applying the upward force to the bottom cover 602. Gravity acting on the top tube 692 will force the bottom cap 602 upward until stopped by a stop device, such as stop bar 700. As shown in fig. 4 and 9, once the upward movement has stopped, the collapsible tent 750 will be in a safe, locked position.

To unlock the collapsible tent 750, the user would need to pull the bottom cover 602 down until the pivot 603 is lower than the pivot 604. Once this occurs, gravity will take over and the collapsible tent 750 will be in the unlocked position as shown in fig. 1 and 3.

In fig. 13, the pivot 603 is lower than the pivot 604. Thus, the user must continue to press the bottom cover 602 upward to overcome the weight of the angled top tube 692.

In fig. 14, the user further presses the bottom cover 602 upward. The inclined top tube 692 further rotates outward. In fig. 14, the pivot 603 is still lower than the pivot 604. Thus, the user must still continue to press the bottom cover 602 upward to overcome the weight of the angled top tube 692.

In fig. 15, the user further presses the bottom cover 602 upward. The pivot 603 is now higher than the pivot 604. Once the pivot 603 becomes higher than the pivot 604, the weight of the angled top tube 692 will cause the bottom cover 602 to move upward such that the user no longer needs to press the bottom cover 602 upward. In FIG. 15, the top tube 692 has begun to rotate inward and the bottom cap 602 is forced upward toward the central top cap 601. The user may now stop pressing the central bottom cover 602 upward. The downward force provided by the angled top tube 692 will move the bottom cover 602 upward until stopped by the central top cover 601.

In fig. 21, the pivot 603 is lower than the pivot 604. Thus, the user must continue to press the bottom cover 602 upward to overcome the weight of the angled top tube 692.

In fig. 22, the user further presses the bottom cover 602 upward. The pivot 603 is now higher than the pivot 604. Once the pivot 603 becomes higher than the pivot 604, the weight of the angled top tube 692 will cause the bottom cover 602 to move upward such that the user no longer needs to press the bottom cover 602 upward. In FIG. 22, the top tube 692 has begun to rotate inward and the bottom cap 602 is forced upward toward the central top cap 601. The user may now stop pressing the central bottom cover 602 upward. The downward force provided by the angled top tube 692 will move the bottom cap 602 upward until stopped by the peg 783.

In fig. 23, the downward force provided by the angled top tube 692 has moved the bottom cap 602 upward such that the upward movement of the connecting rods 693 has been stopped by the pegs 783. The pivot 603 is higher than the pivot 604. The central locking mechanism 722 is now in a self-locking position. It should be noted that the self-locking position is reached after the bottom lid pivot 603 becomes higher than the top tube pivot 604. After this, the user may stop applying the upward force to the bottom cover 602. Gravity acting on the top tube 692 will force the bottom cap 602 upward until the tie rods 693 are stopped by a stop device, such as the pegs 783. As shown in fig. 23, once the upward movement has stopped, the collapsible tent 752 will be in a safe, locked position.

To unlock the collapsible tent 752, the user would need to pull the bottom cover 602 down until the pivot 603 is lower than the pivot 604. Once this occurs, gravity will take over and the collapsible tent 752 will be in the unlocked position as shown in fig. 17 and 18.

Preferred embodiments with a bolt mounted on the connecting rod as a stop means

Fig. 24 and 25 show the peg 783 mounted to the connecting rod 693. This embodiment is similar to the previous embodiment except that the pin 783 is mounted to the connecting rod 693 instead of the top tube 692.

For example, in fig. 25, the downward force provided by the angled top tubes 692 has moved the bottom cover 602 upward such that the upward movement of the connecting rods 693 has been stopped by the pegs 783 contacting the top tubes 692. The pivot 603 is higher than the pivot 604. The central locking mechanism 722 is now in a self-locking position. It should be noted that the self-locking position is reached after the bottom lid pivot 603 becomes higher than the top tube pivot 604. After this, the user may stop applying the upward force to the bottom cover 602. Gravity acting on the top tube 692 will force the bottom cap 602 upward until the upward movement of the connecting rods 693 is stopped by a stop device, such as the pegs 783, that contacts the top tube 692. As shown in fig. 25, once the upward movement has stopped, the collapsible tent 752 will be in a safe, locked position.

Preferred embodiment with stiffening rods

Fig. 26 shows another preferred embodiment of the present invention, wherein a collapsible tent 850 has a plurality of reinforcing poles 802. Each stiffening rod 802 is rotatably connected between the inner telescopic unit 615 and the outer telescopic unit 614. Specifically, in the preferred embodiment shown in fig. 26, each reinforcement bar 802 is shown rotatably connected between a first angled jacking pipe 692 and a location near the junction between the first and

second cornices

671, 672 and the middle cornice 674.

Fig. 27 and 28 show detailed perspective views of the rotational connection of the stiffening rod 802. For example, in fig. 27, the reinforcing rods 802 are shown rotatably connected to the middle cornice 674 via connecting brackets 805. For example, in fig. 28, the reinforcing bar 802 is shown rotatably connected to a first angled jacking tube 692 via a connecting bracket 805.

In fig. 29, the tent 850 has been in the locked deployed position as shown. The stiffening rod 802 is shown disposed between the inner telescopic unit 615 and the outer telescopic unit 614. The reinforcing rods 802 are rigid and will resist external forces acting on the tent 850 that tend to deform the shape of the tent 850 in its locked position. For example, wind blowing towards the locked and deployed tent 850 will not be able to squeeze the outer telescoping units 614 inwardly due to the reinforcement provided by the reinforcement rods 802.

Fig. 30 shows a top view of tent 850 in a locked deployed position. It is clearly shown that the reinforcing bars resist deformation of the shape of the tent 850 in place.

Fig. 31 shows a prior art tent 895 covered in fabric. Wind blows on the sides of the tent 895. Unfortunately, the tent 895 has no way to resist such external forces, and thus its sides deform due to wind forces.

However, fig. 32 shows tent 850 being covered in fabric. Although the wind blows to the side of the tent 820, the tent 850 can maintain its shape. The reinforcing rods 802 (fig. 30) provide optimal support and reinforcement and resist any tendency for the shape of the tent 850 to deform.

While the above preferred embodiments have been described in detail, those skilled in the art will recognize that many changes may be made to the specific embodiments disclosed above without departing from the spirit of the invention. Accordingly, the scope of the invention should be determined by the appended claims and their legal equivalents.
