Description

Technical Field

[0001] This utility model relates to auxiliary support legs, and more particularly to an auxiliary support leg for manual pop-up roofs in RVs. Background Technology

[0002] With social development, the RV industry has grown rapidly, integrating accommodation, dining, transportation, and entertainment. In the tourism sector, RV sales are steadily increasing, as RVs combine the functions of a house and a vehicle. However, due to the limitations imposed by driving requirements, RV size is restricted, resulting in relatively small interior space. Therefore, most RVs have undergone space expansion, primarily through side extensions and rear door extensions, increasing interior space. Currently, RV roof extension technology is developing rapidly. Previously, RV roofs were fixed; now, with extension devices, the roof can be lowered to restore the layout of a standard RV, or raised to expand the interior space and improve its usability.

[0003] Currently, RVs utilize various pop-up roof technologies and mechanisms, primarily for supporting space expansion. However, the increased roof height and wind-exposed area mean that the pop-up mechanism alone cannot prevent roof deformation caused by strong winds or snow accumulation. Therefore, auxiliary support legs are needed to enhance wind and pressure resistance. Furthermore, pop-up roof mechanisms are susceptible to metal fatigue over long-term use, affecting their lifespan and occupant safety. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a manual pop-up roof assist leg for RVs.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a manual pop-up auxiliary support leg for RVs, including a central support plate, an upper support plate that is movably connected to the central support plate and whose support angle is adjusted by an inner gas spring, an upper support seat that is movably connected to the free end of the upper support plate, and a lower support plate that is movably connected to the upper support plate by an outer gas spring. The free ends of the inner and outer gas springs are each equipped with a fisheye connector, and the free ends of the central support plate, the inner gas spring, and the lower support plate on the same side are movably connected to the lower support seat.

[0006] Furthermore, the middle support plate, the upper support plate, and the lower support plate are all U-shaped plates, with the maximum length of the middle support plate being greater than the maximum length of the lower support plate.

[0007] Furthermore, a handle is provided on the front of the free end of the central support plate, and a first positioning lock is also provided on the front of the central support plate that matches the position of the free end of the lower support plate. Positioning holes are provided on the side wall of the central support plate.

[0008] Furthermore, a first connecting lug is machined at one end of the upper support plate and the middle support plate, and a through hole that matches and aligns with the positioning hole is opened on the first connecting lug to allow the connecting bolt to pass through.

[0009] Furthermore, the front of the upper support plate is provided with a second positioning lock that matches the position of the free end of the middle support plate, and the back of the upper support plate is fixedly connected with a first inner mounting seat. The first inner mounting seat is provided with a ball head bolt that matches the fisheye connector of the free end of the inner gas spring.

[0010] Furthermore, ball head bolts that are compatible with the fisheye joints of the external gas spring are installed on the side wall of the upper support plate near the upper support seat.

[0011] Furthermore, the free end of the lower support plate is machined with an external lug for installing ball head bolts. The external lug is connected to the fisheye connector near the outer gas spring via the ball head bolt. The lower support plate is connected to the lower support base via a second connecting lug machined on its other free end, and the second connecting lug is located outside the side wall of the lower support base.

[0012] Furthermore, the front of the lower support is fastened to the RV body, and the back of the lower support is fixedly connected to a second inner mounting seat. The second inner mounting seat is equipped with a ball head bolt that matches the spherical connector near the end of the inner gas spring.

[0013] Furthermore, the upper support has a top contact surface that abuts against the roof of the RV.

[0014] A manual pop-up roof assist leg for RVs adds an adjustable assist leg to the RV roof, forming a support structure outside the pop-up mechanism. This effectively disperses the wind load, snow pressure and external impact force on the roof, slows down the metal fatigue process, reduces the risk of breakage of key components, and extends the service life of the pop-up mechanism.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-4 As shown in the figure, this embodiment relates to the manual lift-up auxiliary support leg for the RV, which provides auxiliary support for the RV roof through manual adjustment. It includes a central support plate 1, an upper support plate 2 that is movably connected to the central support plate 1 and whose support angle is adjusted by an inner gas spring 24, an upper support seat 5 that is movably connected to the free end of the upper support plate 2, and a lower support plate 3 that is movably connected to the upper support plate 2 via an outer gas spring 33. The free ends of the inner gas spring 24 and the outer gas spring 33 are each equipped with a fisheye connector 6. The free ends of the central support plate 1, the inner gas spring 24, and the lower support plate 3 on the same side are movably connected to the lower support seat 4.

[0029] like Figure 1 As shown, the middle support plate 1, the upper support plate 2, and the lower support plate 3 are all U-shaped plates. The maximum length of the middle support plate 1 is greater than the maximum length of the lower support plate 3. It should be noted that when this embodiment is in the position of... Figure 4 When in use as shown, the front of the middle support plate 1, the upper support plate 2, and the lower support plate 3 are all on the same side, that is, the three face the same direction.

[0030] like Figure 1As shown, a handle 11 is provided on the front of the free end of the central support plate 1. The handle 11 is used by the user to grip and apply force. A first positioning lock 14 is also provided on the front of the central support plate 1, which matches the position of the free end of the lower support plate 3. Figure 4 As shown, when this embodiment is in use, the first positioning lock 14 is used to lock the middle support plate 1 and the lower support plate 3. The principle of the first positioning lock 14 is to physically block the lower support plate 3 by turning the knob. A positioning hole 12 is provided on the side wall of the middle support plate 1. The positioning hole 12 is used for positioning connection between the middle support plate 1 and the upper support plate 2.

[0031] Based on this, a first connecting ear 21 is machined at one end of the upper support plate 2 and the middle support plate 1. The first connecting ear 21 has a through hole that matches and aligns with the positioning hole 12 to allow the connecting bolt 13 to pass through. It can be understood that the upper support plate 2 and the middle support plate 1 are movably connected by the through hole of the bolt 13.

[0032] The upper support plate 2 has a second positioning lock 22 on its front side that matches the position of the free end of the middle support plate 1. That is, the length from the bolt 13 to the free end of the middle support plate 1 matches the length from the second positioning lock 22 to the first connecting lug 21, thus enabling the second positioning lock 22 to lock the middle support plate 1, thereby achieving the desired effect. Figure 4 The upper support plate 2 and the middle support plate 1 are mutually locked. The principle of the second positioning lock 22 is to physically block the middle support plate 1 by turning the knob.

[0033] like Figure 3 As shown, a first inner mounting base 23 is fixedly connected to the back of the upper support plate 2. A ball head bolt 7 is provided on the first inner mounting base 23 to be connected to the fisheye connector 6 at the free end of the inner gas spring 24. The fisheye connector 6 and the ball head bolt 7 form a movable connection relationship to support the extension and retraction of the inner gas spring 24. In this embodiment, there are two inner gas springs 24. However, in order to further enhance its support capacity, the number of inner gas springs 24 can be selected according to the actual situation in actual production.

[0034] On the side wall of the upper support plate 2, near the upper support base 5, ball head bolts 7 are installed to connect with the fisheye connectors 6 of the external gas spring 33, achieving the desired effect. Figure 3 As shown in the connection diagram, in this embodiment, there are two external gas springs 33, which clearly indicate that the external gas springs 33 are connected to the left and right sides of the upper support plate 2.

[0035] Next, the free end of the lower support plate 3 is machined with an external lug 32 for mounting ball head bolts 7. The external lug 32 is connected to the fisheye connector 6 near the end of the external support gas spring 33 through the ball head bolts 7, thereby clarifying the connection relationship of the external support gas spring 33. The lower support plate 3 is connected to the lower support base 4 through a second connecting lug 31 machined at its other free end. The second connecting lug 31 is located outside the side wall of the lower support base 4. That is to say, the width of the second connecting lug 31 is greater than the width of the lower support base 4.

[0036] The front of the lower support base 4 is fastened to the RV body, and the back of the lower support base 4 is fixedly connected to the second inner mounting base 41. The second inner mounting base 41 is provided with a ball head bolt 7 that matches the fisheye connector 6 at the near end of the inner support gas spring 24, thereby forming a complete connection relationship of the inner support gas spring 24.

[0037] In addition, the upper support 5 has a top contact surface 51 that abuts against the roof of the RV to support the roof of the RV.

[0038] This application discloses an auxiliary support leg for manual roof lift of a motorhome, which adds an adjustable support leg to the roof of the motorhome, forming a support structure outside the roof lift mechanism. This effectively disperses the wind load, snow pressure and external impact force borne by the roof, slows down the metal fatigue process, reduces the risk of breakage of key components, and extends the service life of the roof lift mechanism.

[0039] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
