Description

Technical Field

[0001] This utility model relates to the field of roof rack technology, and in particular to a side ladder. Background Technology

[0002] Currently, most car climbing ladders use specially designed ladder sections, which have significant drawbacks: These ladder sections need to be specially designed according to specific ladder structures and usage scenarios, and their shape, size, and material selection are all unique. The complex bending or irregular design places extremely high demands on mold development and production processes, which significantly increases the cost of mold manufacturing and material processing. In addition, special high-strength lightweight materials such as aerospace-grade aluminum alloys are often used, further increasing the cost. At the same time, specially designed ladder sections have extremely poor versatility and can only be adapted to one or a few specific ladder structures or vehicle types. Different vehicles have large differences in body height and structural design, making it difficult for one type of ladder section to be universally applicable to multiple vehicles, which greatly limits its scope of use and cannot meet the diverse market demands.

[0062] Figure 1 This is a schematic structural diagram of a side ladder 10 according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 8 This utility model embodiment provides a side ladder 10, including a storage container 100 and a telescopic ladder 200. The storage container 100 defines a receiving cavity that opens to the right, and its top is used to connect to a roof rail or roof rack, while its bottom is used to abut against a side panel of the vehicle body. The telescopic ladder 200 is detachably connected to or will be connected to the storage container 100, and is configured to be in the receiving cavity when retracted, and to form a ladder frame erected between the ground and the storage container 100 when extended.

[0063] In this embodiment, a universal telescopic ladder 200 is used, eliminating the need for complex bends or irregular shapes in specially designed ladder sections. This significantly reduces the reliance on high-precision mold development and special production processes, thereby lowering material processing costs. The telescopic function of the ladder 200 allows for flexible length adjustment, adapting to vehicles of different heights. This breaks the limitation of using specially designed ladder sections for a single purpose, allowing it to be used with various roof rails, roof racks, and side panels of different vehicle structures, covering a wider range of vehicle types and usage scenarios to meet diverse market demands. The telescopic ladder 200 can be disassembled and used by users in other outdoor locations, such as for climbing trees, enhancing the product's practicality and user experience. As a universal component, the telescopic ladder 200 has low manufacturing costs, achieving cost reduction through its use.

[0064] In some other embodiments of this invention, the telescopic ladder 200 can be connected to or will be connected to the storage container 100 by swinging left and right.

[0065] In some other embodiments of the present invention, the telescopic ladder 200 is detachably and swingably connected to or will be connected to the storage container 100.

[0066] In some embodiments of this utility model, the telescopic ladder 200 is a fishing rod ladder made of aluminum alloy, and its maximum unfolded length is greater than or equal to 2 meters.

[0067] Fishing rod ladders are inexpensive to manufacture, thus reducing the overall cost and material expenses. With a maximum unfolded length of 2 meters or more, the side ladder 10 can be matched with the height of most vehicle models.

[0068] In some embodiments of this invention, the top of the telescopic ladder 200 is detachably and / or sway-left-right to the top or bottom of the storage container 100 via a connector. The detachable and sway-left-right functionality achieved by the connector further reduces reliance on the original vehicle structure.

[0069] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the top of the telescopic ladder 200 is connected to the top or bottom of the storage container 100 via a connector. The connector and the telescopic ladder 200 are telescopically connected together in the length direction of the ladder, so that the entire telescopic ladder 200 can extend or retract relative to the storage container 100 via the connector. This arrangement can save the space occupied by the connector, thereby further reducing the overall length of the telescopic ladder 200.

[0070] In some embodiments of this utility model, such as Figure 4 and Figure 8 As shown, the top of the telescopic ladder 200 is connected to the storage container 100 via a connector. The connector includes a rod-shaped, plate-shaped, or bracket-shaped first plug 300 and a locking member for locking the first plug 300. The base of the first plug 300 is rotatably connected to or will be connected to the storage container 100, and its head is inserted into or passes through a correspondingly defined insertion hole 201 on the top of the telescopic ladder 200. Correspondingly, the locking member is detachably or movably connected to the telescopic ladder 200 so that when the first plug 300 is locked by the locking member, the telescopic ladder 200 is locked to the storage container 100 via the connector.

[0071] The first plug 300 of the connector is rotatably installed onto the storage container 100. The head of the first plug 300 is inserted into the pre-set socket 201 at the top of the telescopic ladder 200, completing the initial assembly. The locking component is detachably or movably connected to the telescopic ladder 200 to lock the first plug 300 inserted into the socket 201. After locking, the telescopic ladder 200 is securely connected to the storage container 100 via the connector, preventing it from detaching or rotating at will. When it is necessary to adjust the angle of the telescopic ladder 200 or disassemble it, first release the locking component from the first plug 300. The first plug 300 can then rotate freely around its base, allowing the telescopic ladder 200 to adjust its position. Alternatively, the first plug 300 can be directly pulled out of the socket 201, separating the telescopic ladder 200 from the storage container 100. The locking component allows for flexible installation and disassembly of the telescopic ladder 200 and the storage container 100, improving efficiency and user convenience.

[0072] In some embodiments of this utility model, such as Figure 4 As shown, the locking element includes a pin that elastically extends and retracts in a direction perpendicular to the axis of the insertion hole 201. A locking pin hole 301, which mates with the pin, is defined on the side wall of the first plug 300, so that the locking element can lock and unlock the first plug 300 by inserting and removing the pin into the locking pin hole 301. When the pin extends into the locking pin hole 301, the locking element locks the first plug 300; when the pin retracts and exits the locking pin hole 301, the locking element unlocks the first plug 300.

[0073] In some embodiments of this utility model, such as Figure 8 As shown, after the pin is pulled out of the locking pin hole 301, the first plug 300 can be pulled out of the socket 201, thereby causing the telescopic ladder 200 to be removed from the storage container 100. The removed telescopic ladder 200 can be used as a straight ladder in other outdoor scenarios.

[0074] In some embodiments of this utility model, such as Figure 4 As shown, a guide groove 302 extending from the head end face to the opening of the locking pin hole 301 is defined on the side wall of the first plug 300. The guide groove 302 extends along the insertion and removal direction of the first plug 300, so as to facilitate the head of the pin entering the locking pin hole 301 along the guide groove 302 during the insertion and removal of the first plug 300 in the socket 201. The above configuration eliminates the problem of aligning the socket 201 of the first plug 300 with the pin, and greatly improves the insertion, removal and locking efficiency.

[0075] In some embodiments of this invention, the bottom surface of the guide groove 302 is a slope that gradually extends away from the head end face of the first plug 300, so that during the insertion of the first plug 300 into the socket 201, the bottom of the guide groove 302 presses against the pin and gradually retracts. The slope structure ensures that the retraction of the pin is completely synchronized with the insertion of the first plug 300, eliminating the need for the user to manually press or adjust the pin. Without the slope, if the pin does not retract in advance, forcibly inserting the first plug can easily cause the pin head or the side wall of the first plug to be bumped and deformed.

[0076] In some embodiments of this utility model, such as Figures 5 to 7 As shown, there are two first plugs 300, and at least one first plug 300 is connected to the flipping mechanism via a connecting bolt 400, so that the two first plugs 300 can be flipped relative to the storage container 100 by the flipping mechanism. The connecting bolt 400 also extends in the insertion and removal direction of the corresponding first plug 300, so that the corresponding first plug 300 can rotate relative to the flipping mechanism when the connecting bolt 400 is loose.

[0077] This design allows the telescopic ladder 200 and the two first plugs 300 to be aligned with the bolts loose during factory assembly, and then the bolts can be tightened to secure the telescopic ladder 200 onto the storage container 100. In other words, this facilitates the alignment of the two guide slots 302.

[0078] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the telescopic ladder 200 includes multiple ladder sections nested sequentially from top to bottom, with the top section being the top ladder section 210. The top ladder section 210 includes two tubular top ladder posts 211, with a top step 212 bridging the upper ends of the two top ladder posts 211. Both ends of the top step 212 define mounting holes communicating with the cavities of the top ladder posts 211, forming insertion holes 201 through the entire length or upper section of each mounting hole, or each mounting hole together with the corresponding cavity. Furthermore, two first plugs 300 are arranged opposite each other along the length of the top step 212, and there are two pins, both located between the two insertion holes 201 within the top step 212.

[0079] The above configuration integrates the socket 201 with the telescopic ladder itself and optimizes the layout of the first plug 300 and the pin, which not only ensures the stability of the connection structure but also does not increase the volume of the telescopic ladder, further enhancing the practicality and adaptability of the telescopic ladder 200.

[0080] In some embodiments of this utility model, there is one latch.

[0081] In some embodiments of this utility model, such as Figures 6 to 8 As shown, the top step bar 212 includes a tubular step bar body 213 and a sub-connector integrally formed or fixedly connected to at least one end of the step bar body 213. The sub-connector includes a step post portion 214 and a step bar portion 216. The step post portion 214 defines an assembly hole that is smaller at the top and larger at the bottom, with its larger hole section fitting onto the top step bar 212, and its smaller hole section forming an insertion hole 201. The upper end of the top step post 211 is stopped below the step in the assembly hole, and a bypass opening 215 is defined on the tube wall of its insertion portion. The step bar portion 216 is inserted into the corresponding end of the step bar body 213, and a guide hole 218 is defined on it, communicating with the assembly hole through the bypass opening 215. An inner opening 219 is defined on the front wall of the guide hole 218, and the inner opening 219 communicates with the outer opening on the front side of the step bar body 213. Additionally, the pin is slidably disposed in the guide hole 218 and is fixedly connected to or will be connected to a slide switch, which protrudes from the front side of the outer opening to cause the pin to extend or retract in the guide hole 218 by sliding the slide switch back and forth in the outer opening.

[0082] The upper end of the top ladder column 211 is stopped by a step in the mounting hole, which limits the installation position of the top ladder column 211. The step rod portion 216 is inserted into the end of the step rod body 213. The inner opening 219 on the front side of the guide hole 218 is aligned with the outer opening on the front side of the step rod body 213. The pin is slidably installed in the guide hole 218 and is fixedly connected to the sliding switch exposed from the outer opening. When it is necessary to slide the pin, the sliding switch is activated, causing the pin to move with the sliding switch in the guide hole 218 and exit from the locking pin hole 301, thereby separating the telescopic ladder 200 from the storage container 100.

[0083] In some embodiments of this utility model, such as Figure 5 As shown, the flipping mechanism includes two L-shaped fixed supports 110, which are fixed to the bottom of the receiving cavity of the storage container 100 at a distance from each other. A flip plate 120 is rotatably bridged between the two supports. The front and rear sides of the flip plate 120 are folded to form ear plates 121 that connect to the corresponding fixed supports 110, and / or its right side is folded upward to form a shielding flange 122. Additionally, two first plugs 300 are connected to or will be connected to the flip plate 120.

[0084] This flipping mechanism provides a stable installation base for the first plug 300, gives it a flexible flipping function, and also takes into account the protective effect, further enhancing the advantages of the side ladder 10 in terms of connection flexibility, storage convenience and structural protection.

[0085] In some embodiments of this utility model, such as Figure 4As shown, the head of the first plug 300 is connected to an extension 600 extending along its insertion / removal direction. The extension 600 can also be inserted into or through the socket 201, and at least two positioning pin holes 601 that cooperate with the pin are defined on its side wall. The locking pin holes 301 and the at least two positioning pin holes 601 are on the same side of the first plug 300 and are spaced apart sequentially in the insertion / removal direction of the first plug 300, so as to enable the telescopic ladder 200 to be telescopically and adjustablely locked on the extension 600 by the insertion / removal cooperation of the pin with the at least two positioning pin holes 601.

[0086] At least two positioning pin holes 601 on the extension member 600 are arranged sequentially with the locking pin holes 301 on the first plug 300 in the insertion and removal direction, providing multiple locking positions for the telescopic ladder 200. Users can precisely adjust the overall length of the telescopic ladder 200 according to the actual height of the vehicle, such as the distance from the roof to the ground of different vehicle models, by cooperating the pins with different positioning pin holes 601, making the length of the telescopic ladder 200 more flexible.

[0087] In some embodiments of this utility model, such as Figure 4 As shown, the extension 600 and the first plug 300 are tightly fitted together.

[0088] In some embodiments of this utility model, such as Figure 4 As shown, the first plug 300 is a rod-shaped component with a head that is thinner than its base, and its head is inserted into the extension member 600 so that the outer peripheral surface of the extension member 600 is flush with or inside the outer peripheral surface of the first plug 300. This arrangement achieves an integrated connection between the extension member 600 and the first plug 300, ensuring structural strength, optimizing insertion and removal smoothness, and avoiding additional protrusions at the connection point, further enhancing the practicality and safety of the overall solution.

[0089] In some embodiments of this utility model, when the locking member releases the first plug 300 and the first plug 300 can be dislodged from the socket 201 to enable the telescopic ladder 200 to be removed from the storage container 100, the side ladder 10 also includes at least one optional accessory, which includes a second plug for insertion into or through the socket 201 and locked by the locking member. The second plug may have the same or different structure as the first plug 300.

[0090] The presence of the second plug allows the disassembled telescopic ladder 200 to be used in various ways. The second plug has the same structure as the first plug 300, and both can be connected and disconnected from the socket 201 by locking and unlocking the locking mechanism, thus improving the efficiency of installing and removing the second plug.

[0091] In some embodiments of this invention, at least one optional accessory further includes at least one of a hook, a handrail, and a hinge. The hook's shank is connected to a second plug, and its hook head protrudes from the top of the telescopic ladder 200. The base of the handrail is connected to the second plug, and it protrudes from the top or at least one side of the telescopic ladder 200. The hinge has two rotatably connected ends, each connected to at least one second plug, to facilitate the connection of the telescopic ladder 200 to another telescopic ladder 200 via the hinge to form an A-frame ladder.

[0092] When used alone, the telescopic ladder 200 can be hooked onto other objects to ensure its stability. Handrails protrude from the top or at least one side of the telescopic ladder 200, allowing users to grip them for additional support and improved stability while climbing or standing on it. Connecting two telescopic ladders 200 via hinges to form an A-frame ladder further enhances stability and safety.

[0093] In some embodiments of this utility model, the top of the telescopic ladder 200 is connected to the storage container 100 via a connector. The connector includes an extension 600 extending in the ladder length direction and a locking member for adjustablely locking the extension 600 in the ladder length direction. One end of the extension 600 is rotatably connected to or to be connected to the storage container 100, and its other end is inserted into or passes through a corresponding insertion hole 201 defined on the top of the telescopic ladder 200. It has at least two positioning locking points in the extension direction that cooperate with the locking member. Correspondingly, the locking member is detachably or movably connected to the telescopic ladder 200 so that, during the insertion and removal of the extension 600 from the insertion hole 201, the locking member selectively connects to one positioning locking point, thereby locking the telescopic ladder 200 onto the extension 600.

[0094] One end of the extension piece 600 can rotate freely to connect to the storage container 100. Simultaneously, a secure lock is achieved through the cooperation of the locking component and the positioning lock points, ensuring that angle adjustment and locking position do not interfere with each other. At least two positioning lock points on the extension piece 600 are arranged along the extension direction, and with the selective locking of the locking component, multiple adjustment positions of the telescopic ladder 200's length are achieved.

[0095] In some embodiments of this utility model, such as Figure 1As shown, the telescopic ladder 200 consists of multiple ladder sections nested together from top to bottom, with the lowest section being the bottom ladder section 230. The bottom ladder section 230 includes two bottom ladder posts 231 spaced apart front to back and two bottom ladder steps 232 spaced apart vertically. Each bottom ladder step 232 bridges between two bottom ladder posts 231, forming a U-shaped bottom ladder cavity between the two bottom ladder posts 231 and the two bottom ladder steps 232. Furthermore, the storage container 100 has a limiting boss 130 protruding from the bottom of the receiving cavity. The limiting boss 130 is used to insert into the bottom ladder cavity when the telescopic ladder 200 is fully retracted, and it has at least an upper limit step 131 for stopping the lower side of the upper bottom ladder step 232.

[0096] After the telescopic ladder 200 retracts into the receiving cavity, the limiting boss 130 inserts into the U-shaped cavity of the bottom ladder section 230. Combined with the upper limiting step 131 blocking the upper bottom step 232, the displacement of the telescopic ladder 200 is restricted from the vertical direction, preventing the ladder body from shaking or colliding within the receiving cavity during operation. Compared to non-positioning storage methods, this structure allows the telescopic ladder 200 to always remain in the preset storage position without repeated adjustments, improving ease of use.

[0097] In some embodiments of this invention, an elastic buffer layer is connected to the top surface of the upper limit step 131. The buffer layer is used to separate the upper limit step 131 from the lower bottom step 232. The buffer layer can protect the lower bottom step 232 and the upper limit step 131.

[0098] In some embodiments of this utility model, such as Figure 1 As shown, the limiting boss 130 also has a lower limiting step 132 for stopping the lower bottom pedal on the upper side. The lower limiting step 132 can limit the lower bottom pedal to prevent it from moving up and down.

[0099] In some embodiments of this invention, the limiting boss 130 is integrally formed by cutting and bending from the bottom plate of the accommodating cavity. This design saves on processing and material costs.

[0100] In some embodiments of this invention, a storage cavity is defined within the limiting boss 130. The storage cavity can be used to store the aforementioned optional accessories.

[0101] In some embodiments of the present invention, the receiving cavity also has a downward opening, which is located below the limiting boss 130, so as to cause the bottom of the telescopic ladder 200 to be exposed from the downward opening.

[0102] In some embodiments of this utility model, such as Figures 1 to 3As shown, a lock 500 is provided between the limiting boss 130 and at least one of the two bottom step bars 232, the lock 500 being used to lock the bottom of the telescopic ladder 200 onto the storage container 100.

[0103] In some embodiments of this utility model, the lock 500 is a combination lock, a pin tumbler lock, or a contactless unlocking lock.

[0104] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the lock 500 includes a lock body 501 fixed at the bottom center position on the right side of the limiting boss 130, and the lock body has a latch that can extend and retract in a controlled manner. Correspondingly, the lock also includes a lock seat 502 fixed at the center position on the right side of the bottom step bar 232 on the lower side, and the lock seat 502 defines a lock hole that opens upward and cooperates with the latch.

[0105] In some embodiments of this utility model, the storage container 100 includes a frame-type container formed by connecting metal profiles. The frame-type container defines a receiving cavity. The top of the frame-type container gradually slopes to the left from bottom to top to form a roof connection portion, and its bottom protrudes to the left to form a side panel connection portion. Its front and rear sides have a planar shape. Magnets for magnetically attaching to the side panel of the vehicle body are connected to the side panel. The frame structure of the metal profiles can stably support the weight of the telescopic ladder and the impact force during climbing. Figure 2 As shown, the top slopes upwards and to the left, allowing it to conform to roof rails or roof racks of varying curvatures. This avoids gaps caused by roof slope, improves installation stability, and is compatible with different roof shapes, including sedans and SUVs. The connecting part uses magnets, eliminating the need for drilling or bolts; it can be quickly and magnetically attached to the side panel of the vehicle, simplifying the installation process.

[0106] In some other embodiments of this utility model, the bottom of the frame container protrudes to the left to form a side panel connection, and its front and rear sides adopt a planar shape.

[0107] In some other embodiments of this utility model, the front and rear sides of the frame container are designed with a planar shape.

[0108] In some embodiments of this utility model, the storage container 100 includes a frame-like skeleton formed by connecting metal profiles, and a cover integrally molded from plastic material. The cover is connected to the frame-like skeleton to define a receiving cavity. The frame-like skeleton gradually slopes to the left from bottom to top to form a roof connection portion, and / or its bottom protrudes to the left to form a side panel connection portion. The front and rear sides of the cover have guide slopes, or the front and rear sides are formed by connecting air guide components to form air guide slopes. Magnets for magnetically attaching to the side panel of the vehicle body are connected to the side panel connection portion.

[0109] The metal frame provides stable support for the telescopic ladder's weight and the impact of climbing, preventing deformation over long-term use. The one-piece molded plastic shell is lighter than an all-metal structure, reducing the overall vehicle weight. Furthermore, plastic is easy to process and can be flexibly molded to accommodate the cavity shape. The aerodynamic ramp design reduces wind resistance and noise, enhancing the driving experience.

[0110] In some embodiments of this utility model, such as Figure 1 As shown, the telescopic ladder, when fully retracted, can be completely embedded in the receiving cavity. This design, where the telescopic ladder is fully retracted and embedded in the receiving cavity, completely solves the problems of traditional ladders taking up space and being easily damaged during storage.

[0111] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
