BACKGROUND OF THE DISCLOSURE

Tents are widely used in outdoor activities, and people have increasingly high requirements for use of the tents. The types of foldable tents are numerous, and the folding mode of the tents is also diversified. Due to a frame structure of the tents being complicated, the tent is difficult to store. At present, a top rod piece and a circumferential support rod piece are usually stored separately, are not simple and easy enough, and also cause the problem of not being simple and convenient enough when being unfolded for use.

BRIEF SUMMARY OF THE DISCLOSURE

The present disclosure provides a foldable frame for a tent to realize a function of integratedly and easily storing.

In order to solve the technical problem, a first technical solution of the present disclosure is as follows.

A foldable frame for a tent comprises a center rod, a first moving seat, a second moving seat, a plurality of first supporting rods, and a plurality of second supporting rods. The plurality of first supporting rods and the plurality of second supporting rods are respectively rotatably connected to a circumference of the first moving seat in a rotationally symmetric manner and a circumference of the second moving seat in a rotationally symmetric manner. The plurality of first supporting rods and the plurality of second supporting rods each rotate in vertical planes. A first end, which is away from the second moving seat, of each of the plurality of second supporting rods is connected to each of the plurality of first supporting rods. When the first moving seat is spaced apart from the second moving seat by a use distance, each of the plurality of first supporting rods is angled with respect to each of the plurality of second supporting rods, and a space surrounded by the plurality of first supporting rods defines a receiving space of the tent.

In a preferred embodiment, when each of the plurality of first supporting rods is angled with respect to each of the plurality of second supporting rods at a first angle, the foldable frame is in a use state. When each of the plurality of first supporting rods is angled with respect to each of the plurality of second supporting rods at a second angle, the foldable frame is in a storage state. The second angle is larger than the first angle.

In a preferred embodiment, when the foldable frame is changed from the use state to the storage state, angles between the plurality of first supporting rods and a vertical direction decrease, and angles between the plurality of second supporting rods and the vertical direction decrease.

In a preferred embodiment, a middle portion of the second moving seat comprises a receiving chamber. The center rod comprises a connecting end. When the first moving seat is spaced apart from the second moving seat by the use distance, the connecting end is inserted into the receiving chamber. When the first moving seat is spaced apart from the second moving seat by a storage distance, the connecting end leaves the receiving chamber.

In a preferred embodiment, the connecting end is disposed with an elastic abutting member, the receiving chamber comprises a position-limited opening, and the elastic abutting member enters the receiving chamber and is squeezed by the receiving chamber to undergo elastic deformation. When the elastic abutting member arrives at the position-limited opening, the elastic abutting member reverts to original, and movement of the elastic abutting member along a direction in which the elastic abutting member moves in the receiving chamber is inhibited.

In a preferred embodiment, the elastic abutting member is an elastic piece, the elastic piece comprises a protruding portion, and the elastic piece is disposed in the center rod. The center rod comprises a space-providing opening, and the protruding portion is configured to move out of the center rod through the space-providing opening.

In a preferred embodiment, the position-limited opening is connected with an elastic button. When the elastic piece arrives at the position-limited opening, the protruding portion correspondingly moves into the position-limited opening. When the elastic button is pushed, the protruding portion moves toward a center axis of the center rod to enable the second moving seat to move relative to the center rod.

In a preferred embodiment, a first end, which is away from the first moving seat, of each of the plurality of first supporting rods is rotatably connected with each of a plurality of third supporting rods for increasing a height of the receiving space.

In a preferred embodiment, the foldable frame further comprises a plurality of rotating seats, and each of the plurality of first supporting rods is rotatably connected to each of the plurality of third supporting rods through a respective one of the plurality of rotating seats. Two ends of each of the plurality of rotating seats each comprise a first rotating chamber and an inserting hole, inner walls of two sides of the first rotating chamber each comprise a first rotating hole, and the first end of each of the plurality of first supporting rods is inserted into the inserting hole. A first end of each of the plurality of third supporting rods comprises a rotating mating hole and is disposed in the first rotating chamber. A first rotating pin is disposed in the first rotating chamber to enable a rotatable connection of each of the plurality of third supporting rods and the respective one of the plurality of rotating seats. The first rotating chamber comprises a bottom surface connected to and extending between the two sides of the first rotating chamber, and the bottom surface is configured to enable a rotation of each of the plurality of first supporting rods relative to each of the plurality of third supporting rods to be inhibited along a first rotating direction and to be allowed along a second rotating direction opposite to the first rotating direction.

In a preferred embodiment, the circumference of the first moving seat and the circumference of the second moving seat each comprise a plurality of second rotating chambers, and a plurality of rotating shafts are respectively disposed in the plurality of second rotating chambers. Ends, which are disposed in the plurality of second rotating chambers, of the plurality of first supporting rods and the plurality of second supporting rods each comprise a second rotating hole. The plurality of rotating shafts are inserted in the second rotating holes and rotating mating holes of the plurality of second rotating chambers to enable the plurality of first supporting rods and the plurality of second supporting rods to rotate in the vertical planes.

Compared with the existing techniques, the technical solution has the following advantages.

The present disclosure discloses a foldable frame for a tent. The foldable frame enables the center rod to be locked to or unlocked from the second moving seat through the elastic abutting member cooperating with the position-limited opening and the elastic button in a position-limited manner, so that the center rod can be alternatively locked to the second moving seat, and when the plurality of first supporting rods rotate at a certain angle, the first moving seat can be fixedly limited at a certain position. The foldable frame for the tent is alternatively changed between the use state and the storage state due to the angles between the plurality of first supporting rods and the vertical direction being changed and the angles between the plurality of second supporting rods and the vertical direction being changed. While in use, it is only necessary to push the elastic button to enable the protruding portion not to be limited in the position-limited opening, so that the center rod can move relative to the second moving seat to adjust the angles of the plurality of first supporting rods. The plurality of second supporting rods move, and the relative distance between the first moving seat and the second moving seat are correspondingly changed, so that the angles between the plurality of first supporting rods and the plurality of second supporting rods are correspondingly changed. In this way, when there is a need for the foldable frame to be changed to the use state or the storage state, the center rod is inserted into the second moving seat to enable the protruding portion to be locked to the position-limited opening in a position-limited manner so as to realize locking the second moving seat and the center rod and enable the foldable frame to be locked in the use state. Thereby, the function of integratedly and easily storing is realized.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be further described below in combination with the accompanying drawings and embodiments.

Referring toFIGS. 1-9, a foldable frame for a tent is provided and comprises a center rod1, a first moving seat2, and a second moving seat3, and the first moving seat2and the second moving seat3are disposed on two ends of the center rod1. A plurality of first supporting rods4and a plurality of second supporting rods5are respectively rotatably connected to a circumference of the first moving seat2in a rotationally symmetric manner and a circumference of the second moving seat3in a rotationally symmetric manner. The plurality of first supporting rods4and the plurality of second supporting rods5each rotate in vertical planes. A first end, which is away from the second moving seat3, of each of the plurality of second supporting rods5is connected to each of the plurality of first supporting rods4. When the first moving seat2is spaced apart from the second moving seat3by a use distance and each of the plurality of first supporting rods4is angled with respect to each of the plurality of second supporting rods5, a space surrounded by the plurality of first supporting rods4defines a receiving space of the tent. The circumference of the first moving seat2and the circumference of the second moving seat3each comprise a plurality of second rotating chambers21, and a plurality of rotating shafts219are respectively disposed in the plurality of second rotating chambers21. Ends, which are disposed in the plurality of second rotating chambers21, of the plurality of first supporting rods4and the plurality of second supporting rods5each comprise a second rotating hole217. The plurality of rotating shafts219are inserted in the second rotating holes217and rotating mating holes218of the plurality of second rotating chambers21to enable the plurality of first supporting rods4and the plurality of second supporting rods5to rotate in the vertical planes. Referring toFIG. 3, a rotating sleeve41is sleeved on each of the plurality of first supporting rods4, a second end of each of the plurality of second supporting rods5is disposed with a connecting member51, and the connecting member51is rotatably connected to the rotating sleeve41through one of the second rotating holes217and one of the rotating shafts219to enable each of the plurality of first supporting rods4to be rotatably connected to each of the plurality of second supporting rods5.

Specifically, when each of the plurality of first supporting rods4is angled with respect to each of the plurality of second supporting rods5at a first angle, the foldable frame is in a use state. When each of the plurality of first supporting rods4is angled with respect to each of the plurality of second supporting rods5at a second angle, the foldable frame is in a storage state. The second angle is larger than the first angle. In this embodiment, the first angle is an acute angle, and the second angle is an obtuse angle approximating 180°. When the foldable frame is changed from the use state to the storage state, angles between the plurality of first supporting rods4and a vertical direction and angles between the plurality of second supporting rods5and the vertical direction decrease until the plurality of first supporting rods4and the plurality of second supporting rods5are disposed vertically. At this time, a maximum distance between the first moving seat2and the second moving seat3is formed, and an end of the center rod1leaves the second moving seat3. The maximum distance is equal to a length of each of the plurality of second supporting rods5plus a distance from one end, which is connected to the first moving seat2, of each of the plurality of first supporting rods4to a junction at which each of the plurality of first supporting rods4is rotatably connected to each of the plurality of second supporting rods5.

Specifically, a middle portion of the second moving seat3comprises a receiving chamber211, and the end of the center rod1is a connecting end111. When the first moving seat2is spaced apart from the second moving seat3by the use distance, the connecting end111is inserted into the receiving chamber211, and the foldable frame is changed from the storage state to the use state. When the first moving seat2is spaced apart from the second moving seat3by a storage distance, the connecting end111leaves the receiving chamber211. In this embodiment, the storage distance is the maximum distance.

Specifically, the connecting end111is disposed with an elastic abutting member80, and the receiving chamber211comprises a position-limited opening212. The elastic abutting member80enters the receiving chamber211and is squeezed by the receiving chamber211to undergo elastic deformation. When the elastic abutting member80arrives at the position-limited opening212, the elastic abutting member80reverts to an original shape, and movement of the elastic abutting member80along a direction in which the elastic abutting member80moves in the receiving chamber211is inhibited. Specifically, the elastic abutting member80is an elastic piece8, and the elastic piece8is an elongated elastic piece, of which two ends bend toward each other to form a V-shaped elastic piece. The elastic piece8comprises a protruding portion81. The elastic piece8is disposed in the center rod1, and two sides of the elastic piece8abut an inner wall of the center rod1. The center rod1comprises a space-providing opening101, and the protruding portion81is exposed out of the center rod1through the space-providing opening101. When the center rod1is inserted into the receiving chamber211, the protruding portion81exposed out of the center rod1is squeezed by an inner wall of the receiving chamber211to enable the two sides of the elastic piece8to approach each other and to enable the protruding portion81to move inwardly and enter the receiving chamber211. When the center rod1moves downward until the protruding portion81corresponds to the position-limited opening212, the two sides of the elastic piece8separate from each other due to the protruding portion81not being squeezed by the inner wall of the receiving chamber211, and the protruding portion81passes through the space-providing opening101of the center rod1and enters the position-limited opening212to enable movement between the protruding portion81and the position-limited opening212along a direction in which the center rod1moves to be inhibited to realize the effect of center rod1being fixedly locked within the receiving chamber211.

Referring toFIGS. 6-8, the position-limited opening is connected with an elastic button9. When the elastic piece8arrives at the position-limited opening212, the protruding portion81correspondingly moves into the position-limited opening212. The protruding portion81moves toward a center axis of the center rod1to enable the second moving seat3to move relative to the center rod1when the elastic button9is pushed. The elastic button9comprises an operating sleeve91, a push post92, and a spring93sleeved on the push post92. Specifically, the position-limited opening212is an operating channel31, which is defined by an opening213of the inner wall of the receiving chamber211that extends outward. A cross-sectional area of the operating channel31in a vertical plane is larger than an area of the opening213. The push post92and the spring93move into the operating channel31and do not pass through the opening213to move into an inside of the receiving chamber211due to a size of the opening213. A size of the protruding portion81is smaller than the size of the opening213, so that the protruding portion81can pass through the opening213to move into the operating channel31. A distal end of the operating channel31comprises a vertical position-limited plane311, and a side of the operating sleeve91comprises a reverse hook911. The side of the operating sleeve91abuts the push post92and enters the operating channel31to enable the reverse hook911to be connected to the vertical position-limited plane311so that movement of the operating sleeve91away from the operating channel31is inhibited and movement of the operating sleeve91toward the operating channel31is allowed. When the operating sleeve91is not operated, the protruding portion81passes through the space-providing opening101and the opening213to move into the operating channel31to arrive at a specific location, and the push post92is pushed by the protruding portion81to move away from the center axis of the center rod1. At this time, the center rod1is locked to the second moving seat3, and the foldable frame is in the use state. When there is a need for folding the foldable frame, the operating sleeve91is pushed to push the push post92, and the protruding portion81, which is disposed in the operating channel31, is pushed by the push post92to retreat and leave the operating channel31so that the protruding portion81and the opening213are not position-limited to each other. At this time, the center rod1can be unlocked relative to the second moving seat3. When the center rod1leaves the second moving seat3, the plurality of first supporting rods4and the plurality of second supporting rods5respectively rotate relative to the first moving seat2and the second moving seat3until being disposed substantially vertically, so that the foldable frame can be stored.

Specifically, a first end, which is away from the first moving seat2, of each of the plurality of first supporting rods4is rotatably connected with each of a plurality of third supporting rods10for increasing a height of the receiving space. In this embodiment, the plurality of third supporting rods10is rotatably connected with a plurality of fourth supporting rods11for further increasing the height of the receiving space.

Referring toFIG. 4, the foldable frame further comprises a plurality of rotating seats42, and each of the plurality of third supporting rods10is respectively rotatably connected to each of the plurality of first supporting rods4and each of the plurality of fourth supporting rods11through a respective one of the plurality of rotating seats42. Two ends of each of the plurality of rotating seats42each comprise a first rotating chamber421and an inserting hole422, and inner walls of two sides of the first rotating chamber421each comprise a first rotating hole4211. Since a rotating structure of each of the plurality of first supporting rods4being connected to each of the plurality of third supporting rods10is the same as a rotating structure of each of the plurality of third supporting rods10being connected to each of the plurality of fourth supporting rods11, the rotating structure of each of the plurality of first supporting rods4being connected to each of the plurality of third supporting rods10will be described below for an example. The first end of each of the plurality of first supporting rods4is inserted into the inserting hole422, and a first end of each of the plurality of third supporting rods10comprises a rotating mating hole102and is disposed in the first rotating chamber421. A first rotating pin103is inserted into the first rotating chamber421to realize a rotatable connection of each of the plurality of third supporting rods10and the respective one of the plurality of rotating seats42. The first rotating chamber421comprises a bottom surface connected to and extending between the two sides of the first rotating chamber421, and the bottom surface is configured to enable a rotation of each of the plurality of first supporting rods4relative to each of the plurality of third supporting rods10to be inhibited along a first rotating direction and to be allowed along a second rotating direction.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
