Description

TECHNICAL FIELD The present invention relates to a side pole group of a large foldable tent. BACKGROUND In the prior art, as shown in Figures 1 and 2, the support frame of a foldable large tent generally includes four poles and a top support pole, and three groups of two poles are provided between each adjacent two poles. Cross the support bar group to facilitate folding. It is not difficult to see that, because the structure of the three sets of cross support rod groups of the conventional large tent support frame is the same, when the tent is supported, the three sets of cross support rod groups form a state parallel to the ground, and their low pivotal connections are low. The height of the point B 'limits the height of the side of the tent. Even if the internal height of the tent is sufficient, due to the limitation of the low point B', it is inconvenient for people to bend over to enter and exit the tent. Although it is possible to increase the height of the side of the tent by lengthening four poles, it not only increases the cost, but also for large tents, the four poles carry a heavier weight. The longer the poles, the more unstable the support is. Therefore, it is not economical to increase the height of the side of the tent by extending the poles, and the effect is also poor. SUMMARY OF THE INVENTION An object of the present invention is to provide a side pole group of a large foldable tent, which can increase the height of the low point of the side pole group relative to the pole of the tent in the open state.

To achieve the above objective, the technical solution of the present invention is:

A side pole group of a large foldable tent includes an upper side pole pivotally connected to the top fixed seat of the pole, a lower side pole pivotally connected to a sliding seat movably arranged on the pole, and a middle pivotally connected side pole group. Two middle side rods; the quadrangle formed after the upper and lower side rods and the middle side rods are pivoted to each other satisfies: the length of the middle pivot point of the upper and lower side rods to the end pivot points of the upper and lower side rods and the middle side rods The sum is equal to the sum of the lengths of the central pivot joints of the two middle side rods to the ends of the upper and lower side pivot joints;

Wherein, the length of the lower side rod from its pivotal connection point with the sliding seat to its middle pivot point with the upper and lower side rods is longer than the upper side rod from its pivotal connection point with the fixed seat to its central pivot point with the upper and lower side rods. The length of the contact is long; and the quadrangle formed after the upper and lower side rods and the middle side rod are pivoted to each other satisfies: the middle pivot point of the upper and lower side rods and the middle pivot point of the two middle side rods to the lower side rod and the middle rod The length of the end pivot contact points of the side rods is greater than the length of the middle pivot contact points of the upper and lower side rods and the middle pivot contact points of the two middle side rods to the end pivot points of the upper and middle rods.

At least one of the central pivot joints of each side lever is eccentrically disposed, that is, the central pivot joint is not at the mid-point position of the side lever.

The lengths of the upper side rod and the middle side rod are the same, that is, the length between the two end pivot joints is the same. The middle pivot contact point of the upper side rod and the middle pivot contact point of the middle side rod are both offset, and the positions are The same.

The length from the central pivot point of the upper and lower side rods to the pivot point of the end of the lower side rod is approximately equal to the length from the central pivot point to the pivot point of the upper side rod and the fixed seat.

The upper and lower side levers and the middle side levers are eccentric, that is, the central pivot joints of each side lever are offset, and after eccentricity, the lengths of the two upper levers and the two middle levers are equal, and the middle pivot joints are equal. The positions are the same; at the same time, the length from the middle pivot point of the upper and lower side rods to the end of the lower side rod is equal to the length of the middle pivot point to the upper point and the pivot point of the fixed seat.

The upper and lower side rods are connected with the middle side rod through a coupling member.

After the above solution is adopted, after the tent is supported, the height of the central pivot point of the upper and lower side poles and the end pivot point of the upper side pole and the middle side pole (that is, the low point of the side pole group) can be raised. Therefore, the height of the side of the tent is raised, and the overall height of the tent is not increased, so as to achieve the purpose of facilitating entry and exit; or when the height of the side of the tent is kept constant, the height of the tent pole can be reduced, thereby also However, the overall height of the tent can be reduced.

DETAILED DESCRIPTION As shown in FIGS. 3 and 4, the side bar group according to the present invention is disposed between two adjacent poles 4. For convenience of explanation, according to the length specifications of each side lever of the side lever group, each side lever of the side lever group is divided into an upper side lever 1, a lower side lever 2, and a middle side lever 3. Among them: the upper side rod 1 is a side rod pivotally connected to the top fixed seat 5 of the pole 4; the lower side rod 2 is a side rod pivotally connected to the sliding seat 6 movably arranged on the pole 4; the middle side rod 3 They are two side rods pivotally connected in the middle of the side rod group. At the same time, in order to fold the tent, the quadrangle formed after the upper and lower side rods 1, 2 and the middle side rod 3 are pivotally connected to each other should satisfy the following conditions: that is, the middle pivot point A of the upper and lower side rods 1, 2 To the upper and lower side rods 1, 2 and the middle side rods 3 The sum of the lengths of the end pivot joints B, D is equal to the sum of the lengths of the middle pivot joints C of the two middle side bars 3 to the end pivot joints B, D of the upper and lower side bars 1, 2.

The main difference between the present invention and the conventional structure is that the length of the lower side rod 2 from its pivotal connection point F to the sliding seat 6 to its middle pivot point A to the upper side rod 1 is longer than that of the upper side rod 1 from itself to the fixed seat 5 The length of the pivot point E from the center pivot point A to the middle pivot point A of the lower side rod 2 is long; in this way, after the tent is propped up, the height of the middle pivot point A of the upper and lower side rods 1, 2 can be raised. In addition, the quadrangle formed after the upper and lower side rods 1, 1 and the middle side rod 3 are pivotally connected to each other in the present invention should also satisfy: the middle pivot point A of the upper and lower side rods 1, 2 and the two middle side rods The length of the middle pivot point C of 3 to the end pivot point D of the lower side rod 1 and the middle side rod 3 is longer than the middle pivot point A of the upper and lower side rods 1, 1 and the middle pivot point C of the two middle side rods 3. The sum of the lengths of the pivotal joints B at the ends of the upper side pole 1 and the middle side pole 3; in this way, after the tent is supported, it can be ensured that the point B is moved closer to the point D in the quadrangle, that is, the point B can be raised upwards; otherwise the point B It will not be able to be lifted, but only the pole 4 is outwardly extended (as shown in FIGS. 5A and 5B is a schematic diagram of the comparison between the quadrangle formed by the upper, lower and middle side poles of the present invention and the conventional structure).

In this way, after the tent is propped up, the height of the central pivot joint A of the upper and lower side poles 1, 2 can be raised, and the end pivot joint B of the upper side pole 1 and the middle side pole 3 can be raised, that is, the conventional structure The height of the low point B of the large tent side pole group, so that the side height of the tent is raised relative to the position of the pole 4; the side height of the tent can be increased to achieve the purpose of easy access, or to maintain the tent. When the height of the side is unchanged, the height of the tent pole can be reduced, and the overall folded height of the tent can also be reduced.

It must be mentioned that the length of the lower side rod 2 from its pivotal contact point F with the slide base 6 to its middle pivot point A with the upper side rod 1 is longer than the upper side rod 1 from its contact point E with the fixed base 5 to it The length of the pivot point A with the middle part of the lower side pole 2 is long. When the extended length is sufficient, the angle of the pillar 4 after the support is perpendicular to the ground can be increased, that is, the pole 4 is inclined outward. To achieve a more stable overall support of the tent.

As shown in FIG. 6, which is the first embodiment of the present invention, the traditional concept is to design products with a symmetrical structure. This embodiment is a traditional symmetrical structure design, that is, the central pivot point of each side rod Both A and C are not eccentric, and both are at the midpoint of each side bar. However, since the length of the lower lever 2 from its central pivot point A to the upper lever 1 to its end pivot point D to the middle lever 3 is longer than the length of the upper lever 1 from its central pivot point to the lower lever 2 The length from A to the pivot point E with the fixed seat 5 is long, so that the height of the end pivot point D of the side lever group after folding is higher than the height of the fixed seat 5 at the top of the pole 4, thereby causing the disadvantage of increasing the folded volume. . Moreover, the side bar set of this structure will make the length specifications of the upper and lower side bars 1, 2 and the middle side bar 3 different, so the processing cost of each side bar will be increased, and different parts will be selected during assembly. The side bars also make assembly inconvenient.

In the first embodiment described above, the central pivot joints A and C of each side bar are at the mid-point position. When designing a product, the solution is single, and the size of each side bar is likely to be large. In this solution, the overall effect of raising the side bar group is relatively high. Poor; in fact, as long as the traditional concept is changed, at least one central pivot joint of the side lever is eccentrically set, that is, the central pivot joint is not at the mid-point position of the side lever. In the embodiment, as shown in Figs. 7A, 7B, and 7C, the raising effect of the side rod group is increased. The embodiment of the present invention is eccentrically set at the central pivot joint of a single side rod, and the lower side rod 2 shown in Fig. 7B is used. The embodiment in which the central pivot point A is eccentrically disposed toward the end pivot point D is more effective, because it can greatly reduce the height of the end pivot point D of the side pole group after folding, so as not to increase the tent folding volume. In addition, the above embodiments are described in detail below.

In order to solve the disadvantage of increasing the processing cost of each side bar in the first embodiment, the present invention may

The length of 1 and the middle side rod 3 are set to be the same, that is, the length between the two end pivot joints of the two side rods is the same, so that the entire side rod group has only two lengths of side rods, thereby reducing processing costs. As shown in FIG. 8, this is a second embodiment of the present invention, which is a preferred example when the lengths of the upper rod 1 and the middle rod 3 are equal. This embodiment uses the upper rod 1 and the middle rod 3 The central pivot joints A and C are offset, and at the same time, the positions of the two central pivot joints A and C on the corresponding side poles can also be set to be the same, so that the upper side pole 1 and the middle side pole 3 are not only equal in length, but also The specifications are also the same, which can further reduce the processing cost. When assembling, it is only necessary to distinguish the side bars of two length specifications, which makes the assembly more convenient.

In order to solve the disadvantage of increasing the folding volume in the first embodiment, the present invention can make the length of the central pivot joint A of the upper and lower side rods 1, 2 to the end pivot joint D of the lower side rod 1 approximately equal to the central pivot joint point. The length from A to the pivotal contact point E between the upper side rod 1 and the fixed seat 5. In this way, after the side pole group is folded, the height of the end pivot joint D will be approximately equal to or less than the height of the top fixed seat 5 of the pole 4 so as to achieve the effect of not increasing the volume of the tent after being folded. As shown in FIG. 9, this is a preferred embodiment of this method. In this embodiment, the central pivot joints A of the upper and lower side rods 1 and 2 are eccentrically set, that is, the middle regions of the upper and lower side rods 1 and 2. The contact point A is offset to the end of the two sides of the rod that is pivoted to the center rod 3, so that the length of the center pivot point A to the end pivot point D is approximately equal to Purpose of length. As shown in FIG. 10, it is another preferred embodiment of the foregoing manner. In this embodiment, the central pivot joints A and C of the lower lever 2 and the central lever 3 are eccentrically arranged, that is, the central pivot joint of the lower lever 2. A is shifted to the side of its end pivot point D, and the center pivot point C of the middle side rod 3 is shifted to the side of its end pivot point B, so that the middle pivot point A to the end pivot point is reached. The purpose of the length of D is approximately equal to the length of the central pivot point A to the pivot point E.

As shown in FIG. 11, it is a fifth embodiment of the present invention. This embodiment is a combination of the two solutions described above, that is, the central pivot joints A, C of the upper, lower side rods 1, 2, and the middle side rod 3 are both Eccentric setting, and after eccentric, the two upper side rods 1 and two middle side rods 3 are equal in length, and the positions of the central pivot joints A and C are also the same, so that the two become rods of the same length; The length of the middle pivot point A of the lower side rods 1 and 2 to the end pivot point D of the lower side rod 2 is equal to the length of the middle pivot point A to the pivot point E of the upper side rod 1 and the fixed base 5. This will not only reduce the volume after folding, but also reduce processing costs and make assembly easier.

As shown in FIG. 12, which is a sixth embodiment of the present invention, the upper and lower side rods 1, 2 and the middle side rod 3 according to the present invention may also be connected by interference coupling with each side rod. 7 connection, and the coupling 7 can be applied to all the above solutions. After adding the coupling member 7, the function of the present invention is equivalent to the above solution. Not only that, it can also increase the degree of freedom of rotation of a connection part, making it easier to unfold and fold the side rod group of the present invention, but in a supported state The stability is slightly worse.

The above are the preferred embodiments and design drawings of the present invention. The described preferred embodiments and design The plan is only an example, and is not intended to limit the claims of the present invention. Any implementation with an equal structural design or technical features covered by the "claims" does not depart from the scope of the present invention. The applicant's scope of protection.
