Description

TECHNICAL FIELD

The present disclosure relates to a vehicle rooftop tent, in particular, to a vehicle rooftop tent in which convenience of installation, ease of expansion, and excellence in tent quality are realized with a simple configuration.

BACKGROUND ART

Recently, as interest in camping using vehicles has increased, demand for so-called rooftop tents, which are tents installed on the roofs of cars, is increasing. The rooftop tent refers to a tent installed on the roof of a car, that is, a roof. This rooftop tent can be moved and installed in a state of being mounted on the roof of a car, does not require a separate parking space, and is inexpensive, so the rooftop tent is widely used in recent years.

Since the rooftop tent is used by having the bottom surface fixed on the roof of a car and extending upward, the rooftop tent can be easily installed and removed without being restricted by obstacles or places compared to a tent installed on the ground.

The rooftop tent includes a lower case that is fixed to a roof rack of a car and forms the bottom of the tent and an upper case that forms a resting area as the upper case is deployed to the top along with a cloth covering a side surface during installation, and it is common for the rooftop tent to be moved in a state of being mounted on a vehicle and to form the tent by deploying the upper case upwards and covering the surroundings with the covering cloth at a camping site.

As an example of the prior art related to the rooftop tent (FIG. 1), an “automatic open/close rooftop tent” (Korean Patent No. 10-1318392, registration date: Oct. 8, 2013) is known, and this technology relates to an “automatic open/close rooftop tent”, and specifically, relates to “an automatic rooftop tent which includes a fixed plate fixed to the roof of the vehicle and a bottom plate configured of a rotating plate overlapped with the fixed plate by a driving device and in which the tent is installed on the upper surface of the bottom plate to automatically install or disassemble the tent according to the rotation of the rotating plate so as to install and disassemble the tent”. However, this technology only provides the automatic opening/closing rooftop tent technology, and when the rotating plate is unfolded, not only is there a stability problem with the tent because the tent is not located in the center of the vehicle, but also there is a problem of inconvenience in the installation, disassembly, and use of the tent because the driving device is crude.

As another example of the prior art related to the rooftop tent (FIG. 2), a “space expansion type hard shell rooftop tent for vehicles” (Korean Patent No. 10-1420589, registration date: Jul. 10, 2014) is known, and this technology relates to “a vehicle rooftop tent in which a support pole is lifted by the tent cloth along with drawing out of an extension plate from a lower case mounted on a vehicle roof”. Specifically, the prior art relates to “a vehicle rooftop tent including a lower case that is detachably fixed to the roof of the vehicle and an upper case that closes or opens the lower case by an opening/closing unit, the vehicle rooftop tent including: an extension plate that is slidably connected to the lower case; support poles having both ends pivotably connected to both sides of the rear end of the expansion plate; and a tent cloth connected to at least the upper case, the support pole, and the expansion plate, in which the expansion plate can slide between a first position overlapping the lower case and a second position maximally drawn out from the lower case, the support pole is located adjacent to the extension plate when the extension plate is located at the first position, and is lifted upward by the tent cloth when the extension plate is located at the second position. However, this technology only provides vehicle rooftop tent technology, and when the extension plate slidably connected to the lower case is unfolded, not only is there a stability problem with the tent because the tent is not located in the center of the vehicle, but also there is a problem of inconvenience in the installation, disassembly, and use of the tent because the driving device is crude.

As still another example of the prior art related to the rooftop tent (FIG. 3), a “vehicle rooftop tent” (Korean Patent No. 10-1516916, registration date: Apr. 24, 2015) is known, and this technology is also known as a “vehicle rooftop tent”. The prior art relates to “a vehicle rooftop tent including an extended tent, an annex, and a top tent, in which a variable connection portion is provided in the cover portion that serves as waterproofing by covering an upper portion of the top tent and connections portion of the top tent and the extended tent, and the variable connection portion can stably shield the rooftop tent and the connection portion while being actively deformed according to the shape of the extended tent. Specifically, the prior art relates to “a vehicle rooftop tent including a top tent installed on the roof of the vehicle, an auxiliary tent provided under the top tent, an extension tent connected to a side surface of the auxiliary tent, and a cover portion provided above top of the top tent, in which the cover portion further includes a variable connection portion on a surface corresponding to the position where the extended tent is connected, and the variable connection part has two opening/closing portions, one each in the vertical direction, on both sides of the edge, and an inner skin having a wider width toward the bottom is provided inside the opening/closing portion has a wider width toward the bottom”. However, the technology relates to the installation of the auxiliary tent and the extended tent, and as the vehicle rooftop tent, the structure is complicated and there are problems of inconvenience in installation and disassembly.

As still another example of the prior art related to the rooftop tent (FIG. 4), a “foldable and expandable rooftop tent” (Korean Patent No. 10-1748407, registration date: Jun. 12, 2017) is known, and this technology relates to a “foldable and expandable rooftop tent that includes a tent body installed on a roof of a vehicle and an extension body extending from the tent body. Specifically, the prior art relates to “a foldable and expandable rooftop tent in which a tent body includes a lower cover that is formed of a hard material and has a first driving unit and a second driving unit facing each other on the inside, an upper cover that is formed of a hard material, located to correspond to the upper side of the lower cover, and has a first guide bar and a second guide bar corresponding to the first driving unit and the second driving unit, and a first elevating unit and a second elevating unit that connects the first driving unit of the lower cover and the first guide bar of the upper cover and connects the second driving unit of the lower cover and the second guide bar of the upper cover so that the upper cover can move up and down with respect to the lower cover, and the extension body includes a second hinge body hinge-coupled to a first hinge body of the lower cover, an extension plate inserted and folded between the lower cover and the upper cover by the hinge rotation of the first hinge body and the second hinge body and overlapped or unfolded from between the lower cover and the upper cover, a support frame provided at an end of the extension plate, and a folding ladder in which an upper end is connected to a lower surface of the extension plate”. However, this technology only provides the vehicle rooftop tent technology, and when the folding expansion plate is unfolded, not only is there a stability problem with the tent because the tent is not located in the center of the vehicle, but also there is an inconvenient problem in installation, disassembly, and use of the tent because the driving device is crude.

As still another example of the prior art related to the rooftop tent (FIG. 5), a “rooftop tent opening/closing device” (Korean Patent No. 10-1771155, registration date: Aug. 18, 2017) is known. This technology relates to “a rooftop tent opening/closing device in a rooftop tent equipped with a case opened or closed upward and downward so that the rooftop tent is installed on the roof of a vehicle to allow the user to easily sleep or rest during travel, the upper case is opened by the expansion action of the damper to unfold the tent, and it can be folded after use, in which the upper case is opened by an expansion operation of a damper to unfold the tent, when folded after use, a wire connected to the upper case is wound around a shaft installed in the lower case to close the lower case while contracting the damper that supports the upper case to be open, frames having a plurality of reinforcing bars exhibiting durability and reinforcing power are installed facing each other inside the lower case fixedly installed on a roof rack of the vehicle and the upper case coupled to be opened and closed, a link bent and extended by a pressure of the damper is provided between the frames, a shaft rotated by a driving unit is installed on the outside of the lower reinforcing bar to forcibly bend the link to wind the wire that closes the upper case in the open state, and a pawl operated by operation of the lever exposed to the outside of the lower case is installed to prevent reverse rotation while a ratchet wheel is joined to the shaft and rotational force of the driving unit is applied”. However, the technology only provides the technology to open or close the upper case of the rooftop tent up and down, not only is it unable to provide technology to expand the lower case, but the rooftop opening/closing device is complicated and crude, making it inconvenient to install and disassemble the rooftop tent.

This disclosure is made to solve the above-mentioned problems of the prior arts.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

Embodiments of the present disclosure may be modified in various forms, and in each drawing, the same members are marked with the same reference numerals, and it should be noted that detailed descriptions of known functions and configurations that may unnecessarily obscure the subject matter of the present disclosure are omitted.

A rooftop tent 1000 of the present disclosure is a vehicle rooftop tent 1000 equipped with a function of automatically unfolding both extension plates 1510 connected to a lower case 1500 at the same time as an upper case 1300 is opened. The rooftop tent 1000 can be easily installed and closed after use by men and women of all ages with a one-touch operation and can be installed in most vehicles, and a direction of the tent entrance can also be selected according to a vehicle, and there is little sense of heterogeneity in design.

In addition, by applying premium materials and ergonomic design, the rooftop tent of the present disclosure is a completed rooftop tent that compensates for the disadvantages of the rooftop tent of the prior art, and provides sufficient and spacious space expansion for the whole family to enjoy together and a rich sense of openness with windows on all sides.

In addition, the rooftop tent 1000 of the present disclosure can be said to be a completed rooftop tent that solves all problems such as condensation, height, and mattress generated in the rooftop tent of the prior art. Since the extension plate 1510 connected to both sides of the lower case is opened with one touch in conjunction with the opening of the rooftop tent 1000, in one embodiment, the rooftop tent of the present disclosure provides enough space for a family of four to enjoy together, making it easy and safe for the whole family to enjoy together.

In addition, the rooftop tent 1000 of the present disclosure can set an entrance direction of the rooftop tent 1000 according to a direction of a seat of a driver of the vehicle and solves parking problems such as entering the parking lot with a low height. Moreover, the rooftop tent 1000 of the present disclosure has an aerodynamic design, which can minimize the reduction in fuel efficiency and noise generation of the vehicle when moving while mounted on the roof of the vehicle, and by minimizing the width of the product in the closed state of the rooftop tent, the rooftop tent of the present disclosure has a design that fits well with a variety of vehicles from small cars to large cars, and also has excellent expandability.

In addition, the problem of condensation in the rooftop tent, which was not solved in the prior art, is fundamentally solved by applying a thermally stable composite panel with improved temperature resistance stability through thermal flow simulation, thereby preventing the chronic condensation on the bottom of the rooftop tent in the prior art.

In addition, the exterior design is configured in a streamlined form like a clam shell to give a sense of psychological stability, thereby minimizing wind resistance and securing high user stability even in strong winds such as typhoons.

In addition, in one embodiment, the upper case 1300 adopts a high-strength metal frame and a renewable material (ABS), thereby enabling a structurally stable and eco-friendly consumption cycle product (100% recovery/regeneration cycling system). In one embodiment, the tent 1200 provides a pleasant and comfortable user environment as if breathing in nature by maximizing breathability by applying high-density canvas fabric.

In addition, in one embodiment, a fly material of the tent 1200 blocks UV even in areas with a high UV index to block hazards in safety of a user and maximizes waterproof performance to complement the highly breathable canvas skin.

In addition, in one embodiment of the present disclosure, the pole 1520 has high resistance even in bad weather and ensure safety of the user by adopting a high-stiffness material such as a Duralumin Pole of A70xx series (Duralumin) applied to an aircraft wing.

In addition, a one-action opening function is implemented in the rooftop tent of the present disclosure, so that the rooftop tent can be popped up with one action, which has the advantage of providing considerable convenience to users. In addition, in one embodiment, in the rooftop tent 1000 of the present disclosure, high-strength 100% renewable aluminum that is not deformed even under a uniform load of 1.4 ton is adopted, a shock absorber 1420 that can support a force of up to is applied, and thus, it is possible to install the tent naturally when installing the tent. Moreover, in one embodiment, by providing an access passage for pets as a separate accessory, the harmony between nature, humans, and animals is maximized.

One embodiment of the present disclosure will be described in more detail as follows.

(a) of FIG. 6 illustrates a state where a rooftop tent 1000 of the present disclosure is mounted on a vehicle in an open (installed) state, and (b) of FIG. 6 illustrates a state where the rooftop tent 1000 of the present disclosure is mounted on the vehicle in a closed (folded) state. When the upper case 1300 is pushed upward, the rooftop tent 1000 is unfolded while a link 1410 and the shock absorber 1420 expand. Moreover, by a link structure 1400 located at the corner of the lower case 1500, the extension plate 1510 and pole 1520 are naturally unfolded in conjunction with the opening operation of the rooftop tent 1000, so that the open state of the rooftop tent 1000 is implemented. In a state where the rooftop tent 1000 is open, a hinge fixing device 1440 is fixed to a hinge 1430 located at the center of the link 1410, the pole 1520 is attached to the extension plate 1510 with a webbing strap 1530, and thus, the open state of the rooftop tent 1000 is implemented. Of course, at this time, a ladder 1560 at the entrance and a support 1570 on the opposite side support the extension plate 1510 so that the user can safely use the rooftop tent 1000.

(a), (b), and (c) of FIG. 7 illustrate each step of the opening operation to use the rooftop tent 1000 according to one embodiment of the present disclosure, and illustrate a process in which the extension plate 1510 and the pole 1520 are automatically unfolded in conjunction with each step of the opening operation. In (a) of FIG. 7, when the upper case 1300 is pushed upward, the link 1410 and the shock absorber 1420 start to expand upward with the link structure 1400 as a central axis. (b) of FIG. 7 illustrates a state where the extension plate 1510 and the pole 1520 folded on top of the lower case 1500 are unfolded in conjunction with the opening operation of the upper case 1300 by the link structure 1400 when the upper case 1300 moves upward. (c) of FIG. 7 illustrates a state where the extension plate 1510 and the pole 1520 are completely unfolded in a state in which the upper case 1300 is fully opened. The extension plate 1510 and pole 1520 are stored together on the upper portion of the lower case 1500 in a state where the rooftop tent 1000 is closed, and the extension plate 1510 is unfolded in a straight line with the lower case 1500 but the pole 1520 is not fully unfolded and unfolding of the pole 1520 stops at a position at which a predetermined angle (approximately 45 degrees) with the extension plate 1510 is maintained in a state where the rooftop tent 1000 is fully open. The pole 1520 stops at this position because of tension of the tent 1200 applied to the pole 1520. In this state, the pole 1520 is fixed to the end portion of the extension plate 1510 by the webbing strap 1530.

(a), (b), (c), and (d) of FIG. 8 illustrate each step of the process in which the extension plate 1510 and the pole 1520 are automatically folded in FIG. 7 in the process of opening the rooftop tent 1000 of one embodiment of the present disclosure, in an enlarged manner. Referring to (a), (b), (c), and (d) of FIG. 8, it can be seen that when the rooftop tent (1000) is unfolded, the extension plate 1510 and the pole 1520 are interlocked and automatically unfolded by the link structure 1400. The extension plate 1510 and the pole 1520 are connected to the link structure 1400, and the link structure 1400 is connected to the link 1410. Accordingly, it can be seen that when the link 1410 moves upward, the extension plate 1510 and the pole 1520 connected in conjunction with the link 1410 are naturally unfolded.

(a) of FIG. 9 illustrates a state where the extension plate 1510 and the pole 1520 are unfolded in the open state of the rooftop tent 1000 according to one embodiment of the present disclosure and a state where the webbing strap 1530 fixes the pole 1520 to the end portion of the extension plate 1510. The webbing strap 1530 serves to stably fix the pole 1520 to the end portion of the extension plate 1510. The pole 1520 has both ends connected to the link structure 1400, stored in the upper end of the lower case 1500 when the tent 1200 is closed, and when the tent 1200 is opened.
