Description

Technical Field

[0001] This utility model relates to the field of folding ladders, and in particular to a novel folding ladder. Background Technology

[0002] A household folding ladder is a home tool that combines multifunctionality, convenience, and safety. It features a folding design, allowing it to be easily folded into a smaller size when not in use, making it convenient for storage and carrying. Household folding ladders are usually made of high-strength materials, such as aluminum alloy, which have excellent load-bearing capacity. Their anti-slip pedals and stable support design ensure safety during use.

[0003] The inventors of this application have discovered the following problems during practical use:

[0004] Folding ladders are now widely used, but there is a problem in actual use. Specifically, when operators climb the ladder, the footboards of traditional folding ladders are usually set to be wide. In addition, since folding ladders need to be folded, the projection deviation between two adjacent footboards is relatively small. This makes it easy for users to collide with the edge of the next footboard when lifting their feet, causing the user to sway and posing a certain safety hazard.

[0005] Therefore, it is necessary to provide a new type of folding ladder to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem this invention aims to solve is that traditional folding ladders are prone to collisions with the edge of the next step surface when the user lifts their foot. To address the above-mentioned defects of the existing technology, this invention provides a new type of folding ladder.

[0007] To achieve the above objectives, the technical solution of this utility model is: a novel folding ladder, comprising a folding ladder body, wherein multiple support plates are rotatably arranged on the inner side of the folding ladder body, each support plate comprising a main plate and a secondary plate, wherein the secondary plate is rotatably connected to the main plate via a rotating shaft, and the main plate and the secondary plate are arranged on the same plane.

[0008] By adopting the above technical solution, when an operator is climbing a folding ladder, if the instep of their foot accidentally hits the sub-plate, the sub-plate will first rely on the pivot installed between it and the main plate to rotate flexibly, so that when the sub-plate encounters external force, it will not remain in a rigid state, but can adjust its angle in accordance with the direction of the external force.

[0009] Furthermore, an abutment foot is provided below the main board and the sub-board to limit the rotation angle of the main board and the sub-board.

[0010] By adopting the above technical solution, when using a folding ladder, the sub-board may attempt to rotate due to external forces, but the presence of the abutment feet ensures that this rotation will not occur indefinitely, thereby maintaining the overall stability and structural strength of the ladder.

[0011] Furthermore, both the main board and the sub-board are made of a single injection-molded structure, and the sub-board can have two, but not limited to, width dimensions.

[0012] By adopting the above technical solutions, the sturdiness and durability of the ladder are ensured. The one-piece injection molding structure enables the main board and sub-board to maintain a stable shape when bearing weight and pressure, and is not easy to deform or break, thereby extending the service life of the ladder.

[0013] Furthermore, a groove is provided on one side of the motherboard surface to provide a point of force application for the user on the support plate.

[0014] By adopting the above technical solution, users can apply force through the locking grooves during the folding or unfolding of the ladder, thereby controlling the ladder's movement more easily and accurately.

[0015] Furthermore, a support frame is rotatably connected to one side of the folding ladder body, and a first connecting rod and a second connecting rod are rotatably arranged between the support frame and the folding ladder body to provide folding support force and linkage of the ladder.

[0016] By adopting the above technical solution, the synergistic effect of the support frame and connecting rod ensures that the ladder can fit tightly when folded, reducing space occupation, while providing stable support when unfolded to bear the user's weight. This makes the folding ladder easy to carry and store, and maintains sufficient stability and safety during use.

[0017] Furthermore, the top of the folding ladder body is provided with a cleaning mechanism for cleaning the sweat on the user's hands. The cleaning mechanism includes a cleaning sheet, and the surface and inner side of the cleaning sheet are respectively provided with an adhesive side and a rough side for adhering to the folding ladder body.

[0018] By adopting the above technical solution, the core component of the cleaning mechanism is the cleaning pad, which comes into direct contact with the user's hands and can effectively absorb and clean the sweat on the hands, keeping them dry, thereby improving the user's comfort and safety when climbing. This feature is especially important in high temperature or humid environments.

[0019] As a further feature, two sets of movable wheels are installed on one side of the bottom of the folding ladder body.

[0020] By adopting the above technical solution, when the ladder needs to be moved or transported, the user only needs to push it gently, and the casters will easily rotate, allowing the ladder to be moved quickly and smoothly to the designated location. This not only saves time and effort but also avoids damage to the ladder or injury to the user caused by improper handling.

[0021] Compared with related technologies, the novel folding ladder provided by this utility model has the following beneficial effects:

[0022] This utility model provides a novel folding ladder. Through a support plate, if an operator accidentally kicks the secondary plate while climbing the ladder, the secondary plate will rotate due to the pivot between it and the main plate. This allows the secondary plate to flexibly adjust its angle relative to the main plate when subjected to external force, rather than remaining fixed. Simultaneously, this rotation mechanism effectively reduces the direct obstruction of the user's feet by the secondary plate, minimizing instability caused by collisions. More importantly, it improves user safety, preventing tripping and other accidents caused by foot obstruction to a certain extent.

[0023] This utility model provides a novel folding ladder that employs a cleaning mechanism to firmly adhere a cleaning sheet to the ladder. This ensures the cleaning sheet remains easily accessible to the user's hands, eliminating the need to search for or carry additional cleaning tools and thus improving ease of use. When the user needs to clean their hands of sweat, they simply rub their hands on the cleaning sheet to quickly remove the sweat and keep their hands dry. Furthermore, the combination of adhesive and textured surfaces ensures a secure bond between the cleaning sheet and the folding ladder body. This bond not only prevents the cleaning sheet from falling off or shifting during use but also guarantees its continuous and effective cleaning function. Attached Figure Description

[0029] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0030] Example 1:

[0031] like Figure 1-4 As shown, this utility model discloses a novel folding ladder, comprising a folding ladder body 1. Multiple support plates 2 are rotatably mounted on the inner side of the folding ladder body 1. Each support plate 2 includes a main plate 201 and a secondary plate 202. The secondary plate 202 is rotatably connected to the main plate 201 via a pivot 203. The main plate 201 and the secondary plate 202 are arranged on the same plane. When an operator climbs the folding ladder, if their instep accidentally kicks the secondary plate 202, the secondary plate 202 will first rotate flexibly via the pivot 203 installed between it and the main plate 201. This allows the secondary plate 202 to adjust its angle according to the direction of the external force, rather than remaining rigid. Simultaneously, this rotation effectively reduces the area of ​​the secondary plate 202 obstructing the user's feet, lowering the risk of collision between the feet and the secondary plate 202. More importantly, this design significantly improves the safety performance of the folding ladder, preventing the user from losing balance due to foot obstruction at critical moments, thus avoiding tripping and other dangerous situations.

[0032] like Figure 3 As shown, a stop foot 204 is provided below the main board 201 and the sub-board 202 to limit the rotation angle of the main board 201 and the sub-board 202. When using the folding ladder, the sub-board 202 may try to rotate due to external force, but the presence of the stop foot ensures that this rotation will not be unlimited, thereby maintaining the overall stability and structural strength of the ladder. At the same time, the stop foot also plays a safety protection role, preventing the risk of the user's foot slipping or tripping due to excessive rotation of the sub-board 202, providing the user with a safer and more reliable climbing environment.

[0033] like Figure 3As shown, both the main board 201 and the sub-board 202 are made of a single injection-molded structure. The sub-board 202 has two, but not limited to, width dimensions, ensuring the ladder's sturdiness and durability. The single injection-molded structure allows the main board 201 and the sub-board 202 to maintain a stable shape when bearing weight and pressure, making them less prone to deformation or damage, thus extending the ladder's service life. At the same time, the sub-board 202 has two or more width dimensions, increasing the ladder's applicability and flexibility. Different width dimensions can adapt to different usage scenarios and needs, allowing the ladder to perform optimally in various environments.

[0034] like Figure 3 As shown, a slot 205 is provided on one side of the surface of the main board 201, which serves as a force point for the user to apply force to the support plate 2. During the process of folding or unfolding the ladder, the user can apply force through the slot 205, thereby controlling the movement of the ladder more easily and accurately. This not only improves the convenience of operation, but also ensures the stability and safety of the ladder when folding and unfolding. It can unfold or fold the folding ladder more quickly, improving its ease of use and transportation.

[0035] like Figure 1 , Figure 2 As shown, a support frame 3 is rotatably connected to one side of the folding ladder body 1. A first connecting rod 401 and a second connecting rod 402 are rotatably arranged between the support frame 3 and the folding ladder body 1 to provide folding support force and linkage of the ladder. The synergistic effect of the support frame 3 and the connecting rods ensures that the ladder can fit tightly when folded, reducing space occupation, and can provide stable support when unfolded to bear the weight of the user. This makes the folding ladder easy to carry and store, and can maintain sufficient stability and safety during use. At the same time, the setting of the first connecting rod 401 and the second connecting rod 402 also enhances the linkage of the ladder. During the folding or unfolding of the ladder, the rotation of the connecting rods allows the support frame 3 and the folding ladder body 1 to move synchronously, ensuring the integrity and coordination of the ladder structure.

[0036] Example 2:

[0037] like Figure 1 , Figure 4As shown, a cleaning mechanism 6 is provided on the top of the folding ladder body 1 for cleaning the sweat on the user's hands. The cleaning mechanism 6 includes a cleaning sheet 601. The surface and inner side of the cleaning sheet 601 are respectively provided with an adhesive surface 602 and a textured surface 603 for adhering to the folding ladder body 1. The core component of the cleaning mechanism is the cleaning sheet 601, which comes into direct contact with the user's hands and can effectively absorb and clean the sweat on the hands, keeping the hands dry, thereby improving the user's comfort and safety when climbing. This feature is especially important in high temperature or humid environments. At the same time, the surface and inner side of the cleaning sheet 601 are respectively provided with an adhesive surface 602 and a textured surface 603, which realizes a firm adhesion between the cleaning sheet and the folding ladder body 1.

[0038] like Figure 1 , Figure 2 As shown, two sets of movable wheels 5 are installed on one side of the bottom of the folding ladder body 1. When the ladder needs to be moved or transported, the user only needs to push it gently, and the movable wheels can easily rotate, so that the ladder can be moved to the designated position quickly and smoothly. This not only saves time and effort, but also avoids damage to the ladder or injury to the user caused by improper handling. At the same time, the setting of two sets of movable wheels 5 also enhances the stability and balance of the ladder. When the ladder is placed on uneven ground or needs to be finely adjusted, the movable wheels can be flexibly adjusted to ensure that the ladder always remains stable and balanced.

[0039] In practice, when the folding ladder is needed, the support frame 3 is rotated first, so that the support frame 3 and the main body of the folding ladder 1 form an "A" shape. At the same time, through the action of the first connecting rod 401 and the second connecting rod 402, the support plate 2 is rotated and placed horizontally, completing the unfolding operation of the folding ladder. Then the user uses the folding ladder. When the operator lifts his foot, if the instep kicks the auxiliary plate 202, the auxiliary plate 202 can be rotated with the main plate 201 through the pivot 203. This reduces the obstruction of the auxiliary plate 202 to the user's foot, improves the safety protection of the user, and prevents the user from tripping.

[0040] A cleaning sheet 601 is attached to the outer side of the folding ladder body 1 via an adhesive surface 602 and a textured surface 603. When the user uses the folding ladder, the sweat from their hands can be wiped onto the cleaning sheet 601, thereby improving the user's ease of use of the folding ladder.

[0041] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0042] 1. When the operator lifts his foot to climb the folding ladder, if the instep accidentally kicks the auxiliary plate 202, the auxiliary plate 202 will first rotate due to the pivot 203 set between it and the main plate 201, thus reducing its obstruction to the operator.

[0043] 2. The cleaning sheet 601 is firmly attached to the ladder, so that the cleaning sheet 601 can always be kept in a position that is easily accessible to the user's hands, eliminating the need to find or carry additional cleaning tools, thereby improving ease of use.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
