Description

Technical Field

[0001] This invention relates to the field of climbing tools technology, specifically an easy-to-store and modular climbing device. Background Technology

[0002] Ladders are a common tool in daily life and construction. Workers use ladders, either angled against the outside of buildings or erected on the ground, to climb and perform tasks at height. Therefore, ladders are essential tools for people's work and daily life. Current ladders are generally single-piece structures, difficult to disassemble, heavy, and space-consuming, making them inconvenient to handle and transport. Furthermore, different spaces and locations require smaller lateral dimensions and longer lengths, but single-structure ladders have fixed maximum extension lengths and lateral dimensions, failing to meet the needs of workers in various spatial situations.

[0003] Therefore, there is an urgent need to design and develop an easy-to-store modular climbing device with adjustable width and length, and easy disassembly and assembly, so as to meet the usage requirements and transportation and storage requirements in various spaces. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-store and modular climbing device. The width and length of the ladder can be adjusted arbitrarily, and it is easy to disassemble and assemble, thereby meeting the usage requirements and transportation and storage requirements in various spatial situations.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An easy-to-store modular climbing device includes a vertically arranged left support plate and a right support plate. Both the left and right support plates have multiple mounting openings along their length, extending laterally through the thickness of the plates. The mounting openings on the left and right support plates are positioned in a one-to-one correspondence. The left and right support plates are fixedly connected by multiple connecting pedals. Each connecting pedal has a downward-facing end face latch at both ends or a downward-facing middle latch in the middle. The end face latches at both ends of the connecting pedal can engage with the bottom walls of two spaced-apart mounting openings, and the middle latch in the middle of the connecting pedal can engage with the bottom walls of two abutting mounting openings.

[0007] Furthermore, the left support plate and the right support plate have the same lateral width, and both have the same lateral width as the end face slots at both ends of the connecting pedal. The width of the middle slot in the middle of the connecting pedal is twice the width of the end face slots.

[0008] Furthermore, the vertical height of the connecting pedal is less than or equal to the vertical width of the mounting opening, and the longitudinal width of the connecting pedal is the same as the longitudinal width of the mounting opening.

[0009] Furthermore, the top ends of the left and right support plates are respectively fixedly provided with outwardly extending upper edge platforms, and the bottom ends of the left and right support plates are respectively fixedly provided with outwardly extending lower edge platforms. A connecting rod is fixedly connected between the upper edge platform at the top end of the left support plate and the lower edge platform at the bottom end, and a connecting rod is fixedly connected between the upper edge platform at the top end of the right support plate and the lower edge platform at the bottom end. Pressure blocks corresponding to the ends of the connecting pedals are fixedly provided at intervals on the connecting rods.

[0010] Furthermore, both ends of the connecting rod are provided with external threads and pass through the upper edge platform and the lower edge platform respectively. The upper end of the connecting rod is screwed with an upper locking nut that abuts against the upper edge platform, and the lower end of the connecting rod is screwed with a lower locking nut that abuts against the lower edge platform.

[0011] Furthermore, both the upper and lower edges of the platform are provided with a transverse sliding groove 1 that slides in conjunction with the connecting rod, and both ends of the connecting pedal are provided with a transverse sliding groove 2 that slides in conjunction with the connecting rod.

[0012] Furthermore, the top and bottom ends of the left and right support plates are respectively provided with T-shaped slots. The T-shaped slot at the bottom end of the left support plate is connected to the T-shaped slot at the top end of the other left support plate through an I-shaped plug. The T-shaped slot at the bottom end of the right support plate is connected to the T-shaped slot at the top end of the other right support plate through an I-shaped plug.

[0013] Furthermore, the bottom end of the connecting rod on the outer side of the left support plate is connected to the top end of the connecting rod on the outer side of the other left support plate through a double-threaded sleeve, and the bottom end of the connecting rod on the outer side of the right support plate is connected to the top end of the connecting rod on the outer side of the other right support plate through a double-threaded sleeve. The two ends of the double-threaded sleeve are respectively provided with internal threads in opposite directions, and the two ends of the double-threaded sleeve are respectively threadedly engaged with the ends of the connecting rods.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0015] 1. When assembling and using this invention, if the space is large enough, a connecting pedal with end face snaps at both ends is selected. The connecting pedal is inserted into the corresponding mounting holes of the left and right support plates. The end face snaps at both ends of the connecting pedal are respectively engaged and fixed to the bottom wall of the corresponding mounting holes of the left and right support plates. Then, the connecting rod is inserted from the outside into the transverse sliding groove one on the upper edge platform and the transverse sliding groove two at the end of the connecting pedal. The pressure block on the connecting rod is simultaneously pressed onto the end of each corresponding connecting pedal. Then, the upper locking nut and the lower locking nut are tightened to abut against the upper edge platform and the lower edge platform respectively. This completes the assembly of the climbing device. The operator's feet can step on the middle of the connecting pedal to achieve the purpose of climbing. If the space is relatively narrow, a connecting step with a central locking slot is selected. The central locking slot of the connecting step engages and secures with the bottom walls of the corresponding mounting openings on the left and right support plates. The corresponding mounting openings on the left and right support plates extend longitudinally to one side. Other installation steps are the same. The worker's feet can be inserted into the mounting opening and stepped on the middle of the connecting step to achieve the purpose of climbing. When disassembly for transportation or storage is required, loosen the upper and lower locking nuts, slide the connecting rod outwards, and the pressure block will disengage from the connecting step. Then, move the connecting step upwards to disengage the central locking slot or end face locking slot from the bottom wall of the mounting opening, thus detaching the connecting step. Therefore, the ladder width of this invention is arbitrarily adjustable, and disassembly and assembly are convenient, thereby meeting the usage requirements and transportation and storage requirements of various spatial situations.

[0016] 2. When the usable length of the climbing device needs to be extended, the T-shaped slot at the bottom of the left support plate is connected to the T-shaped slot at the top of the other left support plate using an I-shaped plug. Similarly, the T-shaped slot at the bottom of the right support plate is connected to the T-shaped slot at the top of the other right support plate using an I-shaped plug. The two connecting rods on the left and right sides are then fixedly connected using a double-threaded sleeve. Tightening the double-threaded sleeve secures the two connecting rods, thus extending the assembly length to accommodate higher climbing heights. Therefore, the ladder length of this invention is arbitrarily adjustable and easy to disassemble and assemble, meeting the usage requirements in various spatial situations.

[0017] 3. The climbing device of the present invention can be freely assembled and disassembled. The left support plate, the right support plate, and multiple connecting pedals can be moved separately for multiple times, which facilitates the handling work. Storage only requires the boards to be stacked neatly. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-2 As shown, an easy-to-store modular climbing device includes a vertically arranged left support plate 1 and a right support plate 12. Both the left and right support plates 1 and 12 have multiple mounting openings 2 along their length. These mounting openings 2 extend laterally through the thickness of the left and right support plates 1 and 12, and the mounting openings 2 on the left and right support plates 1 and 12 are positioned in a one-to-one correspondence. The left and right support plates 1 and 12 are fixedly connected by multiple connecting pedals 3. Each connecting pedal 3 has a downward-facing end face latch 4 at both ends or a downward-facing middle latch 5 in the middle. The end face latches 4 at both ends of the connecting pedal 3 can engage with the bottom walls of two spaced-apart mounting openings 2, and the middle latch 5 in the middle of the connecting pedal 3 can engage with the bottom walls of two abutting mounting openings 2. In this case, the mounting opening 2 extends longitudinally through the left and right support plates 1 and 12 to one side, allowing the worker's feet to pass through the mounting opening 2 and step onto the middle of the connecting pedal 3. Figure 6 As shown.

[0027] like Figures 4-5 As shown, the left support plate 1 and the right support plate 12 have the same lateral width, and both are the same lateral width as the end face slots 4 at both ends of the connecting pedal 3. The width of the middle slot 5 in the middle of the connecting pedal 3 is twice the width of the end face slots 4. The vertical height of the connecting pedal 3 is less than or equal to the vertical width of the mounting opening 2, and the longitudinal width of the connecting pedal 3 is the same as the longitudinal width of the mounting opening 2, thereby facilitating the connecting pedal 3 to freely pass into the mounting opening 2.

[0028] like Figures 1-2 As shown, the top ends of the left support plate 1 and the right support plate 12 are respectively fixedly provided with outwardly extending upper edge platforms 6, and the bottom ends of the left support plate 1 and the right support plate 12 are respectively fixedly provided with outwardly extending lower edge platforms 10. A connecting rod 7 is fixedly connected between the upper edge platform 6 at the top end of the left support plate 1 and the lower edge platform 10 at the bottom end, and a connecting rod 7 is fixedly connected between the upper edge platform 6 at the top end of the right support plate 12 and the lower edge platform 10 at the bottom end. Pressure blocks 8 corresponding to the ends of the connecting pedal 3 are fixedly provided on the connecting rod 7 at intervals. Both ends of the connecting rod 7 are provided with external threads and pass through the upper edge platform 6 and the lower edge platform 10 respectively. The upper end of the connecting rod 7 is screwed with an upper locking nut 9 that abuts against the upper edge platform 6, and the lower end of the connecting rod 7 is screwed with a lower locking nut 11 that abuts against the lower edge platform 10. Both the upper edge platform 6 and the lower edge platform 10 are provided with transverse sliding grooves 1 that slide in conjunction with the connecting rod 7, and the two ends of the connecting pedal 3 are respectively provided with transverse sliding grooves 2 16 that slide in conjunction with the connecting rod 7.

[0029] like Figure 3 As shown, the top and bottom ends of the left support plate 1 and the right support plate 12 are respectively provided with T-shaped slots 13. The T-shaped slot 13 at the bottom end of the left support plate 1 is connected to the T-shaped slot 13 at the top end of the other left support plate 1 through an I-shaped insert 14. The bottom end of the connecting rod 7 on the outer side of the left support plate 1 is connected to the top end of the connecting rod 7 on the outer side of the other left support plate 1 through a double-threaded sleeve 15, thereby fixing the left support plate 1 to the other left support plate 1 below it. The T-shaped slot 13 at the bottom end of the right support plate 12 is connected to the T-shaped slot 13 at the top end of the other right support plate 12 through an I-shaped insert 14. The bottom end of the connecting rod 7 on the outer side of the right support plate 12 is connected to the top end of the connecting rod 7 on the outer side of the other right support plate 12 through a double-threaded sleeve 15, thereby fixing the right support plate 12 to the other right support plate 12 below it. The two ends of the double-threaded sleeve 15 are respectively provided with internal threads in opposite directions, and the two ends of the double-threaded sleeve 15 are respectively threaded to the end of the connecting rod 7.

[0030] In this invention, the pressure block 8 on the connecting rod 7 presses against the end of the corresponding connecting pedal 3, serving as a stable limit to prevent the connecting pedal 3 from shifting upwards during operation, thereby locking the connecting pedal 3 in place and ensuring the safety of the operator. When disassembly is required, loosen the upper and lower locking nuts 9 and 11, move the connecting rod 7 slightly upwards, and then slide it outwards to perform subsequent disassembly work.
