Description
Technical Field
[0001] This invention relates to the field of motorhomes, and more specifically, to a structure for converting a motorhome bathroom into a double bed space. Background Technology
[0002] With advancements in technology and improvements in living standards, more and more people are opting for self-driving RV travel and vacations. The main advantage of RVs is that they are not limited by external transportation, accommodation, or dining conditions, and can comprehensively solve problems related to transportation, accommodation, and dining during the journey, giving people a sense of home, while also being very economical.
[0003] However, a major problem with motorhomes, especially Class B self-driving motorhomes, is limited space, making it difficult to arrange longitudinal double beds inside the vehicle. In existing designs, a common approach is to install a transverse double bed at the rear of the vehicle. With this setup, the length of the double bed is usually around 1.8m, and some are even only 1.7m, which seriously affects the comfort of use. Another approach is to install longitudinal single beds, or to use two longitudinal single beds to form a bunk bed. This setup is not in line with current market trends, as current motorhome enthusiasts, especially young couples, are very keen to have comfortable and convenient double beds in their motorhomes. Furthermore, the space utilization is not reasonable enough. For example, the space above the longitudinal single beds is not effectively utilized, and the movement space of each bed in the longitudinal bunk bed is limited, resulting in poor comfort.
[0004] In addition, some existing RVs have bathrooms that are designed to be extended, but these are basically extensions of the bathroom's vertical space. As a result, the space utilization is limited, and it is often impossible to enter the bathroom before the extension, or even after entering, it is impossible to meet basic usage needs, making it inconvenient to use.
[0005] In conclusion, there is an urgent need to develop a new combination structure to solve the aforementioned technical problems. Summary of the Invention
[0006] In view of this, the present invention provides a structure for converting the space of a motorhome bathroom and a double bed, which has the advantages of being able to install a longitudinal double bed in a Class B motorhome, allowing for space reuse of the bathroom and kitchen, and ensuring basic functionality of the bathroom space before expansion. It at least partially solves the problems existing in the prior art. To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0007] A structure for converting a RV bathroom into a double bed space includes a first partition, a second partition, a third partition, and a movable bed board. The first, second, and third partitions are all vertically arranged. The first and second partitions are rotatably connected to a fixed structure inside the vehicle compartment. The third partition is located between the first and second partitions, and its two ends are rotatably connected to the first and second partitions, respectively. The movable bed board is rotatably connected to the fixed bed board.
[0008] When the movable bed board is flipped down and the first, second, and third partitions are in the first position, the bathroom space is compressed. The so-called first position means that the first and third partitions are coplanar and the second partition is perpendicular to the plane formed by the first and third partitions. At this time, the movable bed board and the fixed bed board together form a double bed, and the first, second, and third partitions are located on the outer edge of the movable bed board.
[0009] When the movable bed board is flipped upwards and the first, second, and third partitions are in the second position, the bathroom space is expanded. The so-called second position means that the second and third partitions are coplanar and the first partition is perpendicular to the plane formed by the second and third partitions. At this time, the first, second, and third partitions are located at the outer edge of the fixed bed board.
[0010] As a preferred embodiment, when the first partition, the second partition, and the third partition are in the first position, the second partition is close to the rear wall of the carriage; when the first partition, the second partition, and the third partition are in the second position, the first partition is perpendicular to the side of the carriage.
[0011] As a preferred implementation, when the bathroom space is compressed and the movable bed is lowered, a washbasin is installed under the movable bed; when the bathroom space is expanded and the movable bed is upright, the washbasin is exposed.
[0012] As a preferred embodiment, the lower edges of the first, second, and third partitions are lower than the upper surface of the fixed bed board.
[0013] As a preferred embodiment, a locking structure is provided on the first partition, the second partition, or the third partition, which can fix the first partition, the second partition, and the third partition in a first position or a second position.
[0014] As a preferred implementation, when the bathroom space is compressed and the movable bed is lowered, an induction cooker is also installed under the movable bed.
[0015] As a preferred embodiment, the double bed is arranged longitudinally and is located on one side of the carriage.
[0016] As a preferred implementation, the fixed bed board can still be used as a single bed after the bathroom space is expanded.
[0017] As a preferred implementation plan, the expansion of the bathroom space does not affect access to the bathroom.
[0018] As a preferred implementation, the bathroom is also equipped with a shower head and a portable toilet within its fixed space, and the use of the shower head and portable toilet is not affected before or after the bathroom space is expanded.
[0019] As a preferred implementation, the exterior of the carriage is also equipped with a balcony, and the balcony can be accessed through the toilet both before and after the toilet space is expanded.
[0020] Compared with the prior art, the present invention has the following significant advantages:
[0021] 1. By changing the movable bed board and partition, the bathroom and double bed space can be partially shared. The structure is simple and reliable, and the space utilization rate is high. It is possible to arrange a longitudinal double bed in a Class B motorhome.
[0022] 2. Only the upper part of the bathroom space is transformed, rather than the entire vertical space. Therefore, the lower space of the bathroom can be fully utilized (for installing a shower and a movable toilet, etc.), so that the basic functions of the bathroom can still be met before the space is expanded.
[0023] 3. The bathroom and kitchen spaces can be reused. The washbasin and induction cooker are designed to be hidden and located in a fixed space in the bathroom. The design is ingenious, safe, convenient and reliable to use.
[0024] 4. After the bathroom space is expanded, the fixed bed can be used as a single bed;
[0025] 5. The exterior of the carriage is also equipped with a balcony, which can be reached from both the front and back of the extended toilet. Attached Figure Description

[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0034] Before introducing the specific solution, let's define the double bed of this invention. Due to the limited space in the RV, a bed with a longitudinal length of 1.9m or more is generally sufficient to meet the usage requirements, and a lateral width of 1.1m or more is sufficient to be used as a double bed. A double bed with a lateral width of 1.3m is very comfortable to use. Therefore, the double bed referred to in this invention is a bed with a longitudinal length of 1.9m or more and a lateral width of 1.1m or more.
[0035] like Figures 1 to 4 As shown, a structure for converting a RV bathroom into a double bed space includes a first partition 100, a second partition 200, a third partition 300, and a movable bed board 400. The first partition 100, the second partition 200, and the third partition 300 are all vertically arranged. The first partition 100 and the second partition 200 are rotatably connected to a fixed structure inside the vehicle compartment 600. The third partition 300 is located between the first partition 100 and the second partition 200. Both ends of the third partition 300 are rotatably connected to the first partition 100 and the second partition 200, respectively. The movable bed board 400 is rotatably connected to the fixed bed board 500.
[0036] When the movable bed board 400 is flipped downwards, and the first partition 100, the second partition 200, and the third partition 300 are in the first position, the bathroom space is compressed. The so-called first position means that the first partition 100 and the third partition 300 are coplanar and the second partition 200 is perpendicular to the plane formed by the first partition 100 and the third partition 300. At this time, the movable bed board 400 and the fixed bed board 500 together form a double bed, and the first partition 100, the second partition 200, and the third partition 300 are located at the outer edge of the movable bed board 400.
[0037] When the movable bed board 400 is flipped upwards, and the first partition 100, the second partition 200, and the third partition 300 are in the second position, the bathroom space is expanded. The so-called second position means that the second partition 200 and the third partition 300 are coplanar and the first partition 100 is perpendicular to the plane formed by the second partition 200 and the third partition 300. At this time, the first partition 100, the second partition 200, and the third partition 300 are located at the outer edge of the fixed bed board 500.
[0038] In a preferred embodiment, when the first partition 100, the second partition 200, and the third partition 300 are in the first position, the second partition 200 is close to the rear wall of the carriage 600; when the first partition 100, the second partition 200, and the third partition 300 are in the second position, the first partition 100 is perpendicular to the side of the carriage 600. With this arrangement, when the second partition 200 is pulled, it is limited by the rear wall, which facilitates the positioning of the three partitions. As a further preferred embodiment, the first partition 100 and the second partition 200 are provided with handles to facilitate the switching between the first and second positions of the three partitions.
[0039] As a preferred implementation, when the bathroom space is compressed and the movable bed board 400 is lowered, a washbasin 700 is installed under the movable bed board 400; when the bathroom space is expanded and the movable bed board 400 is vertical, the washbasin 700 is exposed; setting a hidden washbasin 700 can further improve space utilization, and the washbasin 700 can be used for washing hands and face, as well as washing vegetables.
[0040] like Figure 5 , Figure 6 As shown, in a preferred embodiment, the lower edges of the first partition 100, the second partition 200, and the third partition 300 are lower than the upper surface of the fixed bed board 500. With this arrangement, when the movable bed board 400 is lowered, its upper surface restricts the movement of the three partitions, making the three partitions stably and reliably fixed in the first position. When the movable bed board 400 is vertical, pushing the first partition 100 to move the three partitions to the second position, the outer side of the fixed bed board 500 and the movable bed board 400 limit the movement of the three partitions. At the same time, a water-blocking platform can be set on the outer side and bottom of the fixed bed board 500 to prevent water from flowing into the double bed from the bathroom.
[0041] As a preferred embodiment, a locking structure is provided on the first partition 100, the second partition 200, or the third partition 300. The locking structure can fix the three partitions in the first or second position. With this setting, the position of the three partitions is fixed when the movable bed board 400 is vertical, and its shaking is prevented.
[0042] As a preferred implementation, when the bathroom space is compressed and the movable bed board 400 is lowered, an induction cooker 800 is also installed under the movable bed board 400. The induction cooker 800 is located next to the washbasin 700. With this arrangement, the bathroom space and the kitchen space can be reused, further improving the space utilization rate.
[0043] As a preferred implementation, the double bed is arranged longitudinally and is located on the side closest to carriage 600.
[0044] As a preferred implementation, after the bathroom space is expanded, the fixed bed board 500 can still be used as a single bed, thereby further improving the space utilization of the double bed.
[0045] As a preferred implementation, the expansion of the bathroom space does not affect access to the bathroom. Since the change in bathroom space only occurs above some fixed spaces (such as the area above the sink 700 and the induction cooker 800), doors can be installed in other fixed spaces (such as...). Figure 2 As shown in the figure, it does not affect the entry and exit before and after the spatial transformation.
[0046] As a preferred implementation, the fixed space of the bathroom is also equipped with a shower head and a movable toilet. For example, the shower head 810 is set on the side wall below the induction cooker 800, and the movable toilet 710 is set directly below the sink 700. Thus, the use of the shower head 810 and the movable toilet 710 is not affected before and after the bathroom space is expanded. This arrangement can further improve the space utilization and user comfort. Existing designs all involve the expansion of the overall vertical space, so it is difficult to achieve this.
[0047] As a preferred implementation, the exterior of the carriage 600 is also equipped with a balcony 900. The balcony 900 adopts an expandable structure, and the toilet has a door in the fixed space leading to the balcony 900, so that the balcony 900 can be reached from both the front and back of the toilet, further improving the user experience.
[0048] For some motorhomes, the limited length of the 600mm cabin can result in insufficient length of the fixed bed board 500. In such cases, a sofa seat can be installed at the front of the fixed bed board 500, and the back of the sofa seat can be laid flat forward to further extend the length of the double bed.
[0049] The method of using the structure for transforming a motorhome bathroom and double bed space according to the present invention is as follows:
[0050] When the bathroom space is expanded, first flip the movable bed board 400 to make it vertical, then push the first partition 100 to rotate it. When the first partition 100 rotates 90°, its lower part abuts against the outside of the fixed bed board 500, and the lower parts of the second partition 200 and the third partition 300 abut against the movable bed board 400. The three partitions are in the second position and their positions are fixed by the locking device. At this time, the washbasin 700 and the induction cooker 800 are exposed, which is convenient for using the toilet or taking a bath, as well as for cooking, and the space is relatively spacious (at this time, the fixed bed board 500 can be used as a single bed).
[0051] When the bathroom space is compressed, pull the first partition 100 or the second partition 200 to rotate it 90° so that the three partitions are in the first position. Fix their positions with the locking device. At this time, you can still enter and exit the bathroom to use the toilet or take a shower (but the space is a little cramped and the washbasin 700 and induction cooker 800 cannot be used). At the same time, the movable bed board 400 can be flipped down and fixed with the bed board 500 to form a double bed, which is convenient for two people to lie down and rest.
[0052] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.
[0054] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
