Reference numerals in
It is provided according to embodiments of the present application a tent skeleton which simplifies the usage of the tent since users do not need to assemble or disassemble the tent in the process of unfolding or folding the tent.
Hereinafter, technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. The embodiments to be described are only a part, rather than all, of the embodiments of the present application. Based on the embodiments in the present application, all of the other embodiments, made by those skilled in the art without any creative efforts, fall into the protection scope of the present application.
Referring to
The eave poles 2 are articulated at their end portions and are arranged radially. The eave connecting device 3 includes a connecting member body 30 and an eave connecting member 31 that are articulatedly connected. The connecting member body 30 is fixedly arranged on an end portion of the foot pole 1. The eave connecting member 31 is detachably connected to the eave pole. The locating device 4 is configured to fix the foot pole 1.
The eave pole 2 includes an outer tube 20, an inner tube 21 and a locking device 22. The outer tube 20 is fixedly connected to the eave connecting member 31. The inner tube 21 is slidably sleeved to the outer tube 20 and is located in the outer tube 20. The locking device 22 is arranged between the outer tube 20 and the inner tube 21 for locking relative positions of the outer tube 20 and the inner tube 21, thereby locking the length of the eave pole 2.
As can be seen, when unfolding the tent, the length of the eave pole 2 can be elongated by pulling the inner tube 21 outwards, thereby obtaining a larger sun-shading area. When folding the tent, the inner tube 21 can be retracted into the outer tube 20, which will not increase the size of the tent after being folded.
When unfolding the tent skeleton according to the present application, firstly, positions of the foot poles 1 are fixed through the locating devices 4. Then, the inner tubes 21 are pulled outwards from the outer tubes 20. Finally, the inner tubes 21 extended out are locked by the locking devices 22 to thereby lock the lengths of the eave poles 2. In this way, the unfolding of the tent skeleton is completed. When folding the tent skeleton, firstly, the locking devices 22 are unlocked, then the inner tubes 21 are retracted into the outer tubes 20, and then the locating devices 4 are unlocked, and finally the tent skeleton can be folded.
Compared with the existing tent skeleton, it is easier to use the tent skeleton according to the present application since the user does not need to assemble or disassemble the tent skeleton in the process of unfolding or folding the tent skeleton.
It can be understood by those skilled in the art that the locking device 22 may have various structures, for example, each of the outer tube 20 and the inner tube 21 is provided with a locating hole, and an elastic nail having an elastic returning member arranged in the locating holes, thereby the length of the eave pole 2 can be locked, detailed structures of which will not be described herein.
In the tent skeleton according to the above embodiments, as shown in
In order that the eave pole 2 is fixedly connected to the eave connecting member 31 after the skeleton is unfolded, in the tent skeleton according to the above embodiment, referring to
Further, the lock screw 34 is sleeved with a nut to prevent the lock screw 34 from falling off when the lock screw 34 is loosened.
In the tent skeleton according to the above embodiment, the eave pole 2 is fixed via the lock screw 34. In another embodiment of the present application, the same function can be achieved by providing an external thread segment that can be contracted. Referring to
After the eave pole 2 is inserted into the mounting hole 32, the external thread segment 35 can be contracted by tightening the internal thread sleeve 37. The external thread segment 35 will be contracted towards the central axis thereof because of the contraction slot 36 until it is pressed against the surface of the eave pole 2. The eave pole 2 cannot be moved easily since there is a large static friction force between the eave pole 2 and the external thread segment 35, thereby achieving the fixing of the eave pole 2.
It can be conceived that, in the tent skeleton according to the above embodiments, there may be one or a plurality of contraction slots 36. The shape of the contraction slot 36 may be a straight slot parallel to the external thread segment 35 or a helical slot. Preferably, the contraction slot 36 includes two straight slots symmetrically provided on the external thread segment 35.
In the tent skeleton according to the above embodiment, the eave poles 2 are articulated via a top connecting assembly 5. Referring to
Meanwhile, the tent after being folded may have a large size if the eave pole 2 is configured to be long, which is inconvenient to carry; while the tent after being unfolded may have a limited size if the length of the eave pole 2 is configured to be short, resulting in a small sun-shading area. In view of this, as shown in
In the tent skeleton according to the above embodiment, the locating device 4 includes an outer pin locating device and a retractable rod group articulatedly connected with the outer pin locating device.
As shown in
The locating body 40 is provided with a foot pole hole 400 and a pin locating hole 401, and the axis of the foot pole hole 400 is perpendicular to that of the pin locating hole 401. A track groove 402 is provided on the inner surface of the pin locating hole 401, the length direction of the track groove 402 is parallel to the axial direction of the pin locating hole 401, and the track groove 402 communicates the outer surface of the locating body with the inner surface of the pin locating hole 401.
The pin 41 is disposed in the pin locating hole 401. The pin 41 is provided with a track post 410. The track post 410 is slidably disposed in the track groove 402, and the length of the track post 410 is larger than the distance from the inner surface of the pin locating hole 401 to the outer surface of the locating body 40.
The cam knob 42 includes a knob 420 and two connecting pieces 421 fixedly provided on the knob 420. Opposite surfaces of the two connecting pieces 421 are provided with position-limiting grooves 422, and ends of the track post 410 are respectively disposed in the position-limiting grooves 422. Meanwhile, a curved surface portion 423 is provided on the end surface of the end of the connecting piece 421 away from the knob 420, and the curvature radius of the curved surface portion is gradually increased.
The spring 43 is disposed in the pin locating hole 401 and is located between the locating body 40 and the pin 41.
The retractable rod group includes at least one connecting rod group 44. The connecting rod group 44 includes two connecting rods articulated to each other, and an articulating shaft is provided at middle positions of the connecting rods. In each connecting rod group 44, to each of the connecting rods, one end of the connecting rod is articulated to the end of the connecting rod located at different side in another connecting rod group 44, and the other end thereof is articulated to the connecting member body 30 or the locating body 40.
When assembling the above outer pin locating device, firstly, the spring 43 is placed in the pin locating hole 401. Then, the pin 41 is inserted in the pin locating hole 401, and the track post 410 on the pin 41 is located in the track grooves 402. Finally, the pin is pressed into the pin locating hole 401 under an external force such that the track post 410 is embedded and retained in the position-limiting grooves 422 on the cam knob 42, such that the pin 41 is articulated with the cam knob 42.
When being used, the cam knob 42 is turned towards the direction in which the curvature radius of the curved surface portion 423 is larger, meanwhile, the pin 41 articulated with the cam knob 42 is pulled up by the cam knob 42, and thus the locating action is removed. After the cam knob 42 is released, the pin 41 returns back under the action of the spring 43, driving the cam knob 42 to turn towards the direction in which the curvature radius is smaller. The pin after returning back performs the locating function again.
When unfolding the tent skeleton according to the present embodiment, firstly, the outer pin locating device is released such that distances between respective foot poles 1 can be adjusted. Then, ends of the eave poles 2 articulated to one another are held upwards such that the top of the tent skeleton is raised upwards. During the process, the distance between the foot poles 1 is firstly increased and then is decreased. Then, the foot poles 1 are properly located and are locked by the outer pin locating device. Finally, the inner tube 21 in the eave pole 2 is pulled outwards, thereby finishing the unfolding of the tent skeleton.
When unfolding the tent skeleton according to the present embodiment, firstly, the outer pin locating device is driven to move up along the foot pole 1 by the connecting rod group 44 at the side. During the upward movement of the outer pin locating device, the pin thereof is automatically inserted in the locating hole on the foot pole 1. Then, the inner tube 21 of the eave pole 2 is drawn out and is locked by the locking device 22, thereby finishing the unfolding of the tent skeleton.
To fold the tent skeleton, the user only needs to perform the above steps in reverse order.
It can be found that, in the tent skeleton according to the embodiments of the present application, the user only needs to perform such operations as unfolding, locking, unlocking or folding on respective components in the processes of unfolding and folding the tent skeleton. The user does not need to assemble or disassemble the components, which simplifies the usage of the tent.
It can be conceived that, in the tent skeleton according to the present application, the locating device 4 may be implemented in various manners. For example, the tent skeleton may be fixedly connected to the ground by ordinary tent pegs, and may be implemented to have the following structure.
The locating device 4 includes a retractable rod that can be locked and the outer pin locating device in the above embodiment. The outer pin locating device is sleeved on the foot pole 1. One end of the retractable rod is articulated to the outer pin locating device, and the other end thereof is articulated to an adjacent foot pole 1 or another outer pin locating device which is sleeved on the adjacent foot pole 1.
After the tent skeleton is unfolded, an end of the retractable rod may be located by the outer pin locating device, and the length of the retractable rod may be locked by the locking device on the retractable rod, thereby adjacent foot poles 1 are located.
Preferably, the tent skeleton according to the above embodiments may further include an auxiliary supporting pole 6 for helping to support the eave pole 2. Referring to
It can be seen that, in the unfolded tent skeleton, in a case that the eave pole 2 is subjected to a downward pressure, a part of the pressure will be transferred to the foot pole 1 via the auxiliary supporting pole 6, thereby protecting the eave pole 2 from being broken due to an excessively centralized pressure.
It is further provided according to the present application a tent which includes the above tent skeleton and a tarpaulin arranged on the tent skeleton. When using the tent according to the present application, the user does not need to assemble or disassemble the tent skeleton, thus it is convenient to use the tent.
