Description

Technical Field

[0001] This utility model relates to a folding stool, specifically a folding stool for RVs, and belongs to the field of RV equipment technology. Background Technology

[0002] A motorhome, also known as a "home on wheels," combines the functions of a "house" and a "vehicle," but its primary attribute is still that of a vehicle. It is a type of mobile vehicle equipped with essential home amenities. Motorhomes are a fashionable type of vehicle introduced from abroad. The home amenities on a motorhome include: bedding, stove, refrigerator, cabinets, sofa, dining table and chairs, washing facilities, air conditioning, television, audio equipment, and other furniture and appliances. They can be divided into driving area, living area, bedroom area, bathroom area, and kitchen area. A motorhome integrates "clothing, food, housing, and transportation," realizing the fashionable product of "living while traveling and traveling while living." However, because motorhomes generally have a high chassis, folding ladders, also called folding stools, are usually installed to facilitate the entry and exit of people.

[0003] However, most existing folding stools have various problems. For example, in the off-road RV flip-up folding ladder disclosed in CN111497751A, although it can facilitate people to get on and off off-road RVs with high ground clearance, and can be folded and retracted into the skirt under the door when not in use, so as to avoid affecting the appearance and use of the off-road RV, in this technical solution and most current solutions, the folding ladder adopts a scissor-type cross linkage method. This type of folding ladder requires a certain amount of displacement space when it is linked, which results in the overall volume of the folding ladder still being relatively large after folding, and it cannot be fixed to the outside of the vehicle body in a minimized way. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a folding stool for RVs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A folding stool for a motorhome includes a fixed plate, an active plate, a driven plate, and a linkage plate. The fixed plate is fixed to the outer wall of the motorhome. One end of the active plate and the driven plate are rotatably connected to each other. The other end of the active plate is rotatably connected to the fixed plate. The other end of the driven plate is rotatably connected to the center of the linkage plate. One end of the linkage plate is rotatably connected to the fixed plate. The other end of the linkage plate is rotatably connected to a support plate. Two active plates, driven plates, linkage plates, and support plates are symmetrically arranged and combined to form an integral structure. A first pedal is fixed between two adjacent active plates, and a second pedal is fixed between two adjacent linkage plates. The second pedal is located between the driven plate and the support plate.

[0007] As a further embodiment of this utility model: a passive tie rod is rotatably connected to the fixed plate. The passive tie rod is located at the bottom of the linkage plate and is arranged parallel to the linkage plate. The end of the passive tie rod away from the fixed plate is rotatably connected to the support plate, and a docking plate is rotatably connected between the linkage plate and the passive tie rod.

[0008] As a further embodiment of this utility model: the passive pull rod is rotatably connected to the fixed plate via a rotating rod, and a ratchet is coaxially fixed on the rotating rod. The ratchet is located on one side of the fixed plate, and a pawl is rotatably connected to the outside of the fixed plate. One end of the pawl slides against the edge of the ratchet.

[0009] As a further improvement of this utility model: a spring is provided on the side of the fixing plate near the pawl, and one end of the spring abuts against the pawl.

[0010] As a further improvement of this utility model: a pull rope is provided on the pawl, and a protective shell is fixed on the outer wall of the fixing plate. The ratchet and the pawl are both located inside the protective shell, and the pull rope passes through the protective shell.

[0011] As a further improvement of this utility model: both the first pedal and the second pedal are made of stainless steel and form a rectangular structure, and anti-slip textures are provided on their surfaces.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a linkage plate drives the active plate, driven plate, and support plate to move together. This allows the folding stool to rotate on the fixed plate when folded, until the linkage plate is attached to the fixed plate. At this point, the top of the linkage plate is located at the bottom of the active plate, the driven plate is located between the fixed plate and the linkage plate, and the support plate is located outside the linkage plate. This minimizes the thickness of the folding stool after folding, avoiding an increase in the width of the vehicle. At the same time, it can move quickly when unfolded and is supported by the support plate and the fixed plate, making it stable, reliable, and practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1, as Figures 1 to 4 As shown, a folding stool for a motorhome includes a fixed plate 1, an active plate 2, a driven plate 3, and a linkage plate 4. The fixed plate 1 is fixed to the outer wall of the motorhome. One end of the active plate 2 and the driven plate 3 are rotatably connected to each other, and the other end of the active plate 2 is rotatably connected to the fixed plate 1. The other end of the driven plate 3 is rotatably connected to the center of the linkage plate 4, and one end of the linkage plate 4 is rotatably connected to the fixed plate 1. The other end of the linkage plate 4 is rotatably connected to a support plate 5. Two active plates 2, two driven plates 3, two linkage plates 4, and two support plates 5 are symmetrically arranged and combined to form an integral structure. A first pedal 6 is fixed between two adjacent active plates 2, and a second pedal 7 is fixed between two adjacent linkage plates 4. The second pedal 7 is located between the driven plate 3 and the support plate 5.

[0021] In this invention, the linkage plate 4 drives the active plate 2, the driven plate 3, and the support plate 5 to move together. This allows the folding stool to rotate on the fixed plate 1 via the linkage plate 4 when folding, until the linkage plate 4 is attached to the fixed plate 1. At this time, the top of the linkage plate 4 is located at the bottom of the active plate 2, the driven plate 3 is located between the fixed plate 1 and the linkage plate 4, and the support plate 5 is located on the outside of the linkage plate 4. This minimizes the thickness of the folding stool after folding, avoiding increasing the width of the vehicle body. At the same time, it can move quickly when unfolded and is supported by the support plate 5 and the fixed plate 1, making it stable, reliable, and practical.

[0022] Example 2, as Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0023] A passive pull rod 8 is rotatably connected to the fixed plate 1. The passive pull rod 8 is located at the bottom of the linkage plate 4 and is set parallel to the linkage plate 4. The end of the passive pull rod 8 away from the fixed plate 1 is rotatably connected to the support plate 5. A docking plate 9 is rotatably connected between the linkage plate 4 and the passive pull rod 8. The passive pull rod 8 enables the linkage plate 4 to drive the support plate 5 to move synchronously when it rotates, and limits the position of the support plate 5.

[0024] The passive pull rod 8 is rotatably connected to the fixed plate 1 via a rotating rod, and a ratchet 10 is coaxially fixed on the rotating rod. The ratchet 10 is located on one side of the fixed plate 1, and a pawl 11 is rotatably connected to the outside of the fixed plate 1. One end of the pawl 11 slides against the edge of the ratchet 10, and the ratchet 10 is limited by the pawl 11, thereby achieving the overall limiting and locking effect of the passive pull rod 8.

[0025] A spring 12 is provided on the side of the fixed plate 1 near the pawl 11. One end of the spring 12 abuts against the pawl 11, so that one end of the pawl 11 can always abut against the ratchet 10.

[0026] A pull rope 13 is provided on the pawl 11, and a protective shell 14 is fixed on the outer wall of the fixed plate 1. The ratchet 10 and the pawl 11 are both located inside the protective shell 14, and the pull rope 13 passes through the protective shell 14. The pull rope 13 facilitates the operation of the pawl 11 by the user, and the protective shell 14 protects the ratchet 10 and its overall structure.

[0027] Both the first pedal 6 and the second pedal 7 are made of stainless steel and form a rectangular structure. Anti-slip textures are provided on their surfaces. The stainless steel material increases the structural strength of the folding stool, and the anti-slip textures prevent slipping.

[0028] When using this folding stool, first fix the folding stool to the vehicle body using the fixing plate 1. When using it, first pull the pull rope 13 to drive the pawl 11 to rotate, so that one end of the pawl 11 separates from the ratchet 10. After separation, rotate the linkage plate 4. When the linkage plate 4 rotates, the driving plate 2 and the driven plate 3 move in sync, and at the same time drive the support plate 5 to move in sync through the passive pull rod 8 and the docking plate 9, until the support plate 5 and the linkage plate 4 are perpendicular to each other and abut against the ground. Then release the pull rope 13, so that one end of the pawl 11 abuts against the ratchet 10 and locks under the elastic force of the spring 12.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
