Description

Technical Field

[0001] This utility model relates to the field of climbing devices, specifically to a climbing device with handrails. Background Technology

[0002] There are many types of climbing devices, among which the most common are workbenches, escalators, A-frame ladders, climbing frames, and car wash platforms. Currently, the height of climbing equipment on the market varies. Lower climbing devices can be stepped on directly, while higher devices have steps on the sides but no handrails.

[0003] Therefore, a representative example is the patent document with application number CN202321770498.0, which discloses a foldable flip-up ladder with a handrail. When the flip-up ladder is folded, the main ladder frame is kept in contact with the support frame by a second locking structure located on the side of the main ladder frame and the support frame. Because it is located on the side of the main ladder frame and the support frame, the height is low, so there is no requirement for the user's height, making it more convenient for the user to operate.

[0004] Although the aforementioned patent documents disclose a technical solution for adding handrails to escalators, there are still limitations in practical implementation, as follows:

[0005] Taking the technical solution provided in the aforementioned patent document as an example, the handrail is always connected to the escalator. This presents a problem: during the use of the escalator, it needs to be raised and folded for storage. During this process, the handrail needs to be repeatedly raised and lowered. Because the position of the handrail is fixed, the maximum and minimum height of the handrail will not change when it is raised or lowered. However, users have different heights. If a shorter user finds it just right, a taller user may need a higher handrail so that they do not have to bend over to grip the handrail when climbing. In other words, the current handrail has a problem of poor versatility.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] This utility model provides a climbing device with handrails, which aims to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a climbing device with handrails to assist users in climbing from the ground to a high place. The climbing device includes a top plate, support legs, connecting parts, and handrails.

[0009] At least two of the support legs are provided on the side of the ceiling.

[0010] One end of the support leg is in contact with the ground, and the other end is positioned and connected to the ceiling.

[0011] All the support legs are spaced apart to form a pedal space between adjacent support legs; multiple pedals are positioned in the pedal space, and all the pedals are arranged sequentially from bottom to top along the length of the support leg;

[0012] The top plate, the supporting legs, and the foot pedal combine to form a ladder structure; in this ladder structure, the top plate serves as the highest foot pedal.

[0013] The connector has a leg insertion slot, and the support leg is inserted into the leg insertion slot.

[0014] When the support leg is inserted into the leg insertion slot, the connector is positioned and locked at any position along the length of the support leg;

[0015] The connector also has a handrail mounting position, and the handrail is slidably locked in the handrail mounting position so that the handrail can be stored and used.

[0016] When the handrail is retracted, it is positioned between the two support legs, and the upper end of the handrail is below the ceiling.

[0017] When the handrail is in use, the upper end of the handrail extends beyond the ceiling.

[0018] The following is an explanation of the relevant content in the above plan:

[0019] In the above scheme, the top panel can be made of two hinged panels, which allows the ladder structure to be folded, making the ladder structure easier to package and transport.

[0020] In the above scheme, the connector and the support leg can be plugged in and then fixed by screws and other components.

[0021] The handrail is slidably locked in the handrail mounting position, indicating that the handrail and the handrail mounting position on the connector are slidably set. After sliding to the set position, a locking and positioning operation can be performed.

[0022] In the above scheme, the handrail mounting position is a hole, groove or track, which allows the handrail to slide normally, and the locking and positioning can be achieved by screws or other components.

[0023] In a further technical solution, the leg insertion groove is a rectangular groove with an opening, which is matched with the cross-sectional shape of the support leg;

[0024] The depth of the rectangular groove is greater than the width of the support leg.

[0025] The above design allows the support leg to be fully inserted into the rectangular slot.

[0026] In a further technical solution, the opening end of the leg insertion slot is provided with a limiting member to lock and limit the position of the connector.

[0027] The above design ensures that the connector will not easily detach from the support leg after being plugged in.

[0028] A further technical solution, viewed from a cross-sectional perspective, is that the connector includes a main frame, a first vertical plate, a second vertical plate, and a first horizontal plate;

[0029] The end sidewall of the main frame is integrally connected to the first vertical plate, and the second vertical plate is parallel to the first vertical plate and spaced apart. The two ends of the first horizontal plate are integrally connected to the end face of the second vertical plate and the end face of the main frame, respectively.

[0030] The second vertical plate, the first horizontal plate, the end of the main frame, and the first vertical plate combine to form a frame structure with an opening;

[0031] The space within the frame structure is the leg insertion slot.

[0032] The above design ensures that the support legs will not easily wobble after being fixed to the frame structure.

[0033] A further technical solution, viewed from a cross-sectional perspective, is that the main frame includes a first frame horizontal plate, a first frame vertical plate, a second frame horizontal plate, and a second frame vertical plate;

[0034] The first frame horizontal plate, the first frame vertical plate, the second frame horizontal plate, and the second frame vertical plate are connected end to end and combined to form a first quadrilateral structure with mounting holes inside.

[0035] When the connector is positioned on the support leg, the axis of the mounting hole is parallel to the side along the length of the support leg.

[0036] A further technical solution is that a partition plate is provided inside the mounting hole;

[0037] Within the first quadrilateral structure, the partition plate, the first frame horizontal plate, the first frame vertical plate, and the second frame horizontal plate are combined to form a second quadrilateral structure;

[0038] The second quadrilateral structure has a handrail insertion hole, which is the mounting position for the handrail.

[0039] The above design ensures that the handrail is parallel to the side of the support leg along its length.

[0040] A further technical solution is that the side of the handrail has multiple positioning holes, and the multiple positioning holes are arranged along the surface of the handrail in the length direction;

[0041] The connector also includes a locking pin, one end of which passes through the second quadrilateral structure and extends into the armrest socket;

[0042] When the handrail is slidably locked in the handrail mounting position, the locking pin is configured to be inserted into one of the positioning holes.

[0043] With the above design, the handrail can be quickly positioned when it slides to a certain position by the cooperation of the locking pin and the positioning hole.

[0044] In a further technical solution, the connector also includes a mounting base and an elastic element;

[0045] The mounting base is provided at the position corresponding to the second quadrilateral structure on the surface of the second frame horizontal plate. The locking pin passes through the mounting base and can rotate around its own axis so that the locking pin has an unlocked state and a locked state.

[0046] The elastic element acts on the locking pin, forcing the locking pin to maintain its tendency to extend its end into the armrest socket;

[0047] The other end of the locking pin is positioned and connected to a pull ring; the mounting base is provided with a limiting groove with the opening facing the pull ring;

[0048] The pull ring is provided with an abutment surface;

[0049] When the locking pin is in the locked state, the elastic element drives the locking pin to insert into the positioning hole on the handrail.

[0050] To allow the locking pin to enter the unlocked state, the elastic force of the elastic element is overcome, and the locking pin disengages from the positioning hole. The abutting surface abuts against the edge of the limiting groove to keep the locking pin in the disengaged state.

[0051] The above design allows the handrail to be quickly fixed in place.

[0052] In a further technical solution, the two ends of the handrail have a first limiting block and a second limiting block, respectively;

[0053] When the handrail slides on the handrail mounting position, the first limiting block and the second limiting block respectively limit the downward sliding distance and the upward sliding distance of the handrail.

[0054] The above design ensures that the handrail will not detach from the connecting parts during the sliding process.

[0055] In a further technical solution, the surface edges of both the first vertical plate and the second vertical plate are recessed towards one side of the first horizontal plate to form a notch, which serves as a pedal overlap groove.

[0056] When the support leg is inserted into the leg insertion slot, the pedal overlap slot is configured to overlap with the upper surface of a certain pedal to lock the connector.

[0057] The above design allows the connectors to be quickly secured.

[0076] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0078] See appendix Figures 1-9 As shown, a climbing device with handrails is used to assist users in climbing from the ground to a high place. The climbing device includes a ceiling 1, support legs 2, connectors 3 and handrails 4.

[0079] At least two of the supporting legs 2 are provided on the side of the ceiling 1;

[0080] One end of the support leg 2 is in contact with the ground, and the other end is positioned and connected to the ceiling 1;

[0081] All the support legs 2 are spaced apart to form a pedal space between adjacent support legs 2; multiple pedals 5 are positioned in the pedal space, and all the pedals 5 are arranged sequentially from bottom to top along the length direction of the support leg 2;

[0082] The top plate 1, the supporting leg 2, and the foot pedal 5 are combined to form a ladder structure; in this ladder structure, the top plate 1 serves as the highest foot pedal.

[0083] The connector 3 has a leg insertion groove 6, and the support leg 2 is inserted into the leg insertion groove 6;

[0084] When the support leg 2 is inserted into the leg insertion slot 6, the connector 3 is positioned at any position along the length of the support leg 2 and locked.

[0085] The connector 3 also has a handrail mounting position 7, and the handrail 4 is slidably locked on the handrail mounting position 7 so that the handrail 4 has a storage and use state;

[0086] When the handrail 4 is retracted, the handrail 4 is located between the two support legs 2, and the upper end of the handrail 4 is below the ceiling 1;

[0087] When the handrail 4 is in use, the upper end of the handrail 4 extends beyond the ceiling 1.

[0088] In this embodiment, the top plate 1 can be configured as two plates hinged together, allowing the ladder structure to be folded, facilitating its packaging and transportation. See details for further information. Figure 1 and Figure 2 .

[0089] The handrail 4 is slidably locked on the handrail mounting position 7, indicating that the handrail 4 and the handrail mounting position 7 on the connector 3 are slidably set. After sliding to the set position, a locking and positioning operation can be performed.

[0090] In this embodiment, the connector 3 and the support leg 2 can be plugged into each other, and then fixed by screws or other components. For example, the screws on the connector 3 abut against the support leg 2 to complete the locking and positioning.

[0091] In this embodiment, the handrail mounting position 7 is a hole, groove, or track, which allows the handrail 4 to slide normally. The locking and positioning can be achieved by components such as screws, for example, by the screws passing through the connector 3 and abutting against the handrail 4.

[0092] In this invention, the handrail 4 can be freely extended to a suitable height through the cooperation of the connector 3 and the handrail 4, so that the handrail 4 has wide applicability and high flexibility. When used, it can not only be used in a variety of different situations or fields, but also can be adjusted or customized according to specific needs. Specifically, through the insertion combination of the support leg 2 and the leg insertion slot 6, the connector 3 can be set at a certain position on the support leg 2, and then locked at that position. When the handrail 4 is needed, it is directly guided to slide on the handrail mounting position 7 of the connector 3, so that the upper end of the handrail 4 extends beyond the ceiling 1 until the height of the handrail 4 is suitable for the user.

[0093] In a further technical solution, the leg insertion groove 6 is a rectangular groove with an opening, which is matched with the cross-sectional shape of the support leg 2;

[0094] The depth of the rectangular groove is greater than the width of the support leg 2.

[0095] With the above design, the support leg 2 can be fully inserted into the rectangular groove, wherein the inner contour of the rectangular groove is customized according to the outer contour of the support leg 2 to ensure that the two fit tightly together, thereby providing stable support. Then, considering the requirements of durability and friction, the insertion groove can be made of metal, and the contact surface can be appropriately surface treated (such as polishing or adding texture) to enhance grip and reduce wear.

[0096] Furthermore, guide ramps or guide ribs can be provided at the opening or inside of the rectangular groove to help the support leg 2 slide into place more easily and accurately.

[0097] In a further technical solution, the opening end of the leg insertion slot 6 is provided with a limiting member 8 to lock and limit the position of the connector 3.

[0098] To further reinforce the connection after the support leg 2 is inserted and prevent loosening or accidental detachment, the above design can be used to ensure that the connector 3 will not easily detach from the support leg 2 after insertion.

[0099] The limiting component 8 can be a bolt, a pin, or a cover that is interference-fitted with the open end of the leg insertion slot 6.

[0100] A further technical solution, viewed from a cross-sectional perspective, is that the connector 3 includes a main frame 9, a first vertical plate 10, a second vertical plate 11, and a first horizontal plate 12;

[0101] The end sidewall of the main frame 9 is integrally connected to the first vertical plate 10, and the second vertical plate 11 is parallel to and spaced apart from the first vertical plate 10. The two ends of the first horizontal plate 12 are integrally connected to the end face of the second vertical plate 11 and the end face of the main frame 9, respectively.

[0102] The second vertical plate 11, the first horizontal plate 12, the end of the main frame 9, and the first vertical plate 10 are combined to form a frame structure 13 with an opening;

[0103] The space within the frame structure 13 is the leg insertion slot 6.

[0104] With the above design, the support leg 2 will not easily wobble after being fixed to the frame structure 13.

[0105] It should be noted that the first vertical plate 10, the end of the main frame 9, and the first horizontal plate 12 combine to form an L-shaped structure. This is the preferred shape after the three are combined. Compared with the first vertical plate 10 and the end of the main frame 9 being inclined, the two being parallel and on the same straight line helps the support leg 2 to be engaged, and the stability is better after engagement.

[0106] A further technical solution, viewed from a cross-sectional perspective, is that the main frame 9 includes a first frame horizontal plate 14, a first frame vertical plate 15, a second frame horizontal plate 16, and a second frame vertical plate 17.

[0107] The first frame horizontal plate 14, the first frame vertical plate 15, the second frame horizontal plate 16, and the second frame vertical plate 17 are connected end to end and combined to form a first quadrilateral structure 18 with mounting holes inside.

[0108] When the connector 3 is positioned on the support leg 2, the axis of the mounting hole is parallel to the side of the support leg 2 along its length.

[0109] In a further technical solution, a partition plate 19 is provided inside the mounting hole;

[0110] Within the first quadrilateral structure 18, the partition plate 19, the first frame horizontal plate 14, the first frame vertical plate 15, and the second frame horizontal plate 16 are combined to form the second quadrilateral structure 20.

[0111] The second quadrilateral structure 20 has a handrail insertion hole, which is the handrail mounting position 7.

[0112] With the above design, the handrail 4 is parallel to the side of the support leg 2 along its length.

[0113] When the connector 3 is fixed to the support leg 2, the axis of the mounting hole is parallel to the length direction of the support leg 2. This means that the mounting hole is set along the direction of the support leg 2, ensuring that any component inserted into the mounting hole will be aligned with the support leg 2. The second quadrilateral structure 20 has a handrail insertion hole inside, which is the location for installing the handrail. Due to the presence of the partition plate 19, the position of the handrail insertion hole is determined, and the handrail 4 can be inserted into this hole for installation.

[0114] The main purpose of the above design is to ensure that all components, including the support legs 2 and the handrails, are installed correctly in the predetermined direction and position, thereby ensuring the stability, aesthetics and functionality of the entire structure.

[0115] In a further technical solution, the side of the handrail 4 has a plurality of positioning holes 21, and the plurality of positioning holes 21 are arranged along the surface of the handrail 4 in the length direction;

[0116] The connector 3 also includes a locking pin 22, one end of which passes through the second quadrilateral structure 20 and extends into the armrest insertion hole;

[0117] When the handrail 4 is slidably locked on the handrail mounting position 7, the locking pin 22 is configured to be inserted into one of the positioning holes 21.

[0118] With the above design, the handrail 4 can be quickly positioned when it slides to a certain position by the cooperation of the locking pin 22 and the positioning hole 21.

[0119] On the side of the handrail 4, a plurality of positioning holes 21 are provided along its length. These positioning holes 21 are used to provide different position options, allowing the user to adjust the height of the handrail as needed.

[0120] When a user wants to adjust the position of the handrail, they can do so by sliding the handrail bar 4.

[0121] Since the locking pin 22 can work with multiple positioning holes 21 distributed along the handrail 4, when the handrail 4 slides to a certain positioning hole 21 and the locking pin 22 is aligned, the locking pin 22 can be quickly inserted into the positioning hole 21 to achieve rapid positioning.

[0122] This design not only improves the speed and efficiency of adjusting the armrest position, but also ensures the stability after adjustment, while simplifying the user's operation process and enhancing the user experience.

[0123] In a further technical solution, the connector 3 also includes a mounting base 23 and an elastic element 24;

[0124] The mounting base 23 is provided at the position corresponding to the second quadrilateral structure 20 on the surface of the second frame horizontal plate 16. The locking pin 22 passes through the mounting base 23 and can rotate around its own axis so that the locking pin 22 has an unlocked state and a locked state.

[0125] The elastic element 24 acts on the locking pin 22, forcing the locking pin 22 to maintain the tendency of its end to extend into the armrest socket;

[0126] The other end of the locking pin 22 is positioned and connected to a pull ring 26; the mounting base 23 is provided with a limiting groove 27 with the opening facing the pull ring 26;

[0127] The pull ring 26 is provided with an abutment surface 28;

[0128] When the locking pin 22 is in the locked state, the elastic element 24 drives the locking pin 22 to insert into the positioning hole 21 on the handrail 4;

[0129] To allow the locking pin 22 to enter the unlocked state and overcome the elastic force of the elastic element 24, the locking pin 22 disengages from the positioning hole 21, and the abutting surface 28 abuts against the edge of the groove of the limiting groove 27 to keep the locking pin 22 in the disengaged state.

[0130] The above design allows the handrail 4 to be quickly fixed in place.

[0131] Mounting base 23 provides a mounting point for locking pin 22 and allows locking pin 22 to rotate about its own axis. Locking pin 22 is a movable component that can rotate within mounting base 23 and can be pushed into or pulled out of positioning hole 21. Locking pin 22 has two states: unlocked and locked. In the locked state, locking pin 22 is inserted into positioning hole 21 on handrail 4, preventing movement of handrail 4; in the unlocked state, locking pin 22 is disengaged from positioning hole 21, allowing handrail 4 to be removed or repositioned. The elastic element 24 (such as a spring or tension spring) applies a force to locking pin 22, causing it to tend to extend its end into positioning hole 21. This means that, without external force, locking pin 22 will automatically attempt to enter the locked state.

[0132] In use, the user can manually operate the locking pin 22 by pulling the ring 26. When the locking pin 22 is in the locked state, the elastic element 24 pushes the locking pin 22 into the positioning hole 21 on the handrail 4, while the pulling ring 26 is in the limiting groove 27. However, the pulling ring 26 has an abutment surface 28. When the locking pin 22 needs to be in the unlocked state, the user can pull the pulling ring 26 to overcome the elastic force of the elastic element 24, causing the locking pin 22 to disengage from the positioning hole 21 on the handrail 4. At this time, rotating the pulling ring 26 will cause the abutment surface 28 to contact and press against the edge of the limiting groove 27 of the mounting base 23, helping the locking pin 22 to remain in this unlocked position.

[0133] The limiting groove 27 on the mounting base 23 is used to cooperate with the abutment surface 28 on the pull ring 26 to ensure that the locking pin 22 will not easily return to the locked state in the unlocked state unless the user releases the pressure on the pull ring 26.

[0134] In a further technical solution, the two ends of the handrail 4 are respectively provided with a first limiting block 29 and a second limiting block 30;

[0135] When the handrail 4 slides on the handrail mounting position 7, the first limiting block 29 and the second limiting block 30 respectively limit the downward sliding distance and the upward sliding distance of the handrail 4.

[0136] Thanks to the above design, the handrail 4 will not detach from the connecting piece 3 during the sliding process.

[0137] Both the first limiting block 29 and the second limiting block 30 can be selected to use screws or bolts, or either one can be used.

[0138] The first limiting block 29 and the second limiting block 30 are located at both ends of the handrail 4. Their function is to limit the sliding range of the handrail 4 on the handrail mounting position 7 and prevent the handrail 4 from sliding excessively and dislodging from the connector 3.

[0139] The first limiting block 29 limits the downward sliding distance. When the handrail 4 slides downward to a certain position, the first limiting block 29 will gradually contact the upper edge of the handrail mounting position 7, that is, the first limiting block 29 will contact the edge of the partition plate 19 and / or the edge of the first frame vertical plate 15. Figure 8 and Figure 9 As shown, the first limiting block 29 contacts the upper edge of the partition plate 19 and the first frame vertical plate 15.

[0140] The second limiting block 30 limits the upward sliding distance. When the handrail 4 slides upward to a certain position, the second limiting block 30 will contact the partition plate 19. This contact prevents the handrail 4 from rising further, thus preventing it from sliding completely out of the connector 3.

[0141] Through the design of the two limiting blocks mentioned above, the movement of the handrail 4 is strictly controlled within a certain range, regardless of how it slides. Even if the user applies a large force, the handrail 4 will not accidentally detach from the connecting piece 3 due to exceeding the predetermined sliding range. This design increases safety during use, especially in cases where the handrail 4 may be subjected to external impacts or vibrations.

[0142] This design not only enhances safety but also improves the user experience. Users no longer need to worry about the handrail 4 suddenly falling or slipping out during normal use, reducing potential risks. Furthermore, this design helps maintain the device's clean appearance, as the handrail 4 is always held in the correct position.

[0143] In a further technical solution, the surface edges of the first vertical plate 10 and the surface edges of the second vertical plate 11 are both recessed towards the first horizontal plate 12 to form a notch, which is a pedal overlap groove 25.

[0144] When the support leg 2 is inserted into the leg insertion slot 6, the pedal overlap slot 25 is configured to overlap with the upper surface of a certain pedal 5 to lock the connector 3.

[0145] The above design allows connector 3 to be quickly secured.

[0146] Specifically, the support leg 2 is correctly inserted into the leg insertion slot 6, and the pedal overlap slot 25 is guided to mate with the upper surface of a certain pedal 5. In this case, the engagement of the support leg 2 and the leg insertion slot 6 can initially position the connector 3. However, the connector 3 is still prone to sliding up and down along the support leg 2. Therefore, when the support leg 2 is inserted into the leg insertion slot 6, the pedal overlap slot 25 is simultaneously engaged with the upper surface of a certain pedal 5 (the user needs to determine which pedal 5 is being used; that is, if the user wants a higher handrail 4, a higher pedal 5 is placed, and vice versa), so that the connector 3 is locked.

[0147] Working principle:

[0148] During installation, the support leg 2 is correctly inserted into the leg insertion slot 6, and the pedal overlap slot 25 is guided to mate with the upper surface of a certain pedal 5. In this case, the engagement of the support leg 2 and the leg insertion slot 6 can initially position the connector 3. However, the connector 3 is still prone to sliding up and down along the support leg 2. Therefore, when the support leg 2 is inserted into the leg insertion slot 6, the pedal overlap slot 25 is simultaneously engaged with the upper surface of a certain pedal 5 (the user needs to determine which pedal 5 is being used; for example, if the user wants a higher handrail 4, a higher pedal 5 should be placed, and so on). This locks the connector 3 in place.

[0149] Next, the connector 3 is matched and positioned with the handrail mounting position 7, that is, the connector 3 is inserted into the handrail socket. Then, the first limiting block 29 and the second limiting block 30 are installed on both ends of the handrail 4 respectively (during the above process, the locking pin 22 is in the unlocked state).

[0150] Then guide the locking pin 22 to lock the handrail 4. For details, please refer to... Figure 1 and Figure 2 Then, if the handrail 4 is needed, the unlocking pin 22 guides the handrail 4 to slide upward. When it slides to a certain position, the second limiting block 30 will contact the partition plate 19. This contact prevents the handrail 4 from rising further, thus preventing it from sliding completely out of the connector 3. Then the locking pin 22 is driven to lock the handrail 4.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
