The present invention will be described in more detail by referring to the following embodiments.

Please refer to Figures 1 to 3. Figure 1 shows a schematic diagram of the appearance of a handrail ladder set 1 according to an embodiment of the present invention. Figure 2 is an exploded view of a free footrest structure 10 of the handrail ladder set 1, Figure 3 It is an exploded view of the structure of an armrest footrest structure 20 of the armrest ladder group 1. The handrail ladder group 1 includes a free footrest structure 10 and a handrail footrest structure 20. The detailed structures, materials and functions of these two structures will be detailed below.

Compared with the armrest footrest structure 20, the free footrest structure 10 does not include an armrest device. The free foot board structure 10 includes two free foot boards (for the convenience of description, they are respectively called an upper free foot board 111 and a lower free foot board 112), two first side plates 12 and at least one lateral fixing strip 13. The upper free foot pedal 111 and the lower free foot pedal 112 are components for the user to step on and gradually raise their height. The lower free foot board 112 is located lower, and the upper free foot board 111 is higher. In practice, the free foot pedal can be a flat board. The appearance shape of the upper free footrest 111 and the lower free footrest 112 can be the same, or they can have different but similar shapes, and even the thickness can be different, which can be designed according to actual needs. In terms of materials, the free foot pedal can be made of laminated board, solid wood board, bamboo board or plastic board.

The first side plate 12 is used to erect the upper free footrest 111 and the lower free footrest 112. With respect to the two free footrests, the two first side plates 12 are separately provided on the left and right. The two first side plates 12 have the same appearance and shape, and each form two ladder legs 121, an upper free footrest fixing platform 122, and a lower free footrest fixing platform 123. An upper free foot pedal 111 is fixed on the two upper free foot pedal fixing platforms 122, and a lower free foot pedal 112 is fixed on the two lower free foot pedal fixing platforms 123. The fixing method can be connected with wooden boards, connected with hardware, fixed with nails or fixed with glue. Since the free footrest structure 10 needs to be moved frequently, the first side plate 12 may form a hollow portion 124, and the hollow portion 124 can be used for the user to lift the free footrest structure 10 with both hands. In terms of materials, the first side panel 12 can be made of laminated panels or solid wood panels.

If there are only the first side plates 12 on both sides and the upper free footrest 111 and the lower free footrest 112 above them, the free footrest structure 10 is easy to shake due to foot use, and may even be disassembled due to excessive weight. Therefore, the horizontal fixing strip 13 is designed to strengthen the stability of the overall structure. According to the present invention, the number of the horizontal fixing bars 13 may be more than one. In this embodiment, two horizontal fixing bars 13 are used as an example for illustration. Both ends of each transverse fixing strip 13 are respectively fixed on the inner side of the two first side plates 12 below the upper free footrest fixing platform 122. The fixing method can also be, but is not limited to, wooden board connection hardware connection, nail fixing or glue fixing. The two transverse fixing strips 13 can be fixed to the inner side of the first side plate 12 respectively, or they can be fixed to the inner side of the first side plate 12 after being fixed to each other. In terms of materials, the horizontal fixing strip 13 can be made of laminated board, solid wood board or bamboo board.

The armrest footrest structure 20 includes an armrest footrest 21, two armrest bending rods 22, two second side plates 23, two armrest bending rod fixing plates 24 and at least one transverse fixing bar 25. The armrest pedal 21 is an element for the user to step on to reach the highest height, and two perforations 211 are respectively provided on both sides of the long end. In terms of materials, like the free pedal, the armrest pedal 21 can be made of laminated board, solid wood board, bamboo board or plastic board.

The armrest bending rod 22 is an element used to allow the user to hold with his hands and stabilize the body, no matter whether the user's foot is stepped on the free pedal or the armrest pedal 21. The front shape of each armrest bending rod 22 is close to the "" shape, and its two ends respectively pass through a long end and two through holes 211 of the armrest footboard 21. The armrest bending rod 22 may be a hollow structure or a solid structure. For safety reasons, the latter is better. In terms of material, the material of the armrest bending rod 21 can be metal or alloy.

The second side plate 23 is a component used to erect the armrest footrest 21. Each second side plate 23 forms two ladder legs 231 and an armrest footrest fixed platform 232. The armrest pedal 21 is fixed on the two armrest pedal fixing platform 232. The fixing method can be connected with wooden boards, connected with hardware, fixed with nails or fixed with glue. Since the armrest footrest structure 20 also needs to be moved frequently, the second side plate 23 can form at least one hollow portion 233, which can be used for the user to lift the armrest footrest structure 20 with both hands. Since the second side plate 23 is higher than the first side plate 12, the second side plate 23 is formed with two hollow parts 233 in this embodiment. The user can select the hollow part 233 to hold the armrest footrest structure 20 according to his needs. In terms of materials, the second side board 23 is the same as the first side board 12, and a laminated board or solid wood board can be used as the material.

The armrest bending rod 22 itself is a long strip, and it is not feasible to fix it only by the perforation 211 of the armrest footboard 21. Therefore, the armrest bending rod fixing plate 24 is designed. Each armrest bending rod fixing plate 24 is fixed on the inner side of one second side plate 23, and two slots 241 are opened in the armrest bending rod 22 to insert two ends of an armrest bending rod 22. The fixing method can be nailed or glued. In other words, an armrest bending rod 22 will be fixed by two perforations 211 and two slots 241, so that it is relatively stable. In terms of materials, the material of the armrest bending rod fixing plate 24 can be a laminated board, a solid wood board or a plastic board.

Similarly, if there are only the second side panels 23 on both sides and the armrest footrest 21 above it, the armrest footrest structure 20 is easy to shake due to foot use, and even disassemble due to excessive weight. Therefore, the horizontal fixing strip 25 is designed to strengthen the stability of the overall structure. According to the present invention, the number of horizontal fixing bars 25 may be more than one. In this embodiment, two horizontal fixing bars 25 are used as an example for illustration. Two ends of each lateral fixing strip 25 are respectively fixed on the inner side of the two second side plates 23. The fixing method can also be wood board connection hardware connection, nail fixing or glue fixing. Like the horizontal fixing strip 13, the two horizontal fixing strips 25 can be fixed to the inner side of the second side plate 23 respectively, or they can be fixed to each other first and then fixed to the inner side of the second side plate 23 together. In terms of materials, the horizontal fixing strip 25 can be made of laminated board, solid wood board or bamboo board.

The free footrest structure 10 and the upper free footrest 111 of the upper free footrest fixed platform 122 abut the armrest footrest structure 20, and the position of the armrest footrest 21 is higher than the positions of the free footrests, As shown in Figure 1. If the armrest ladder group 1 is not used properly, the free footrest structure 10 and the armrest footrest structure 20 can be separated into two chairs for users to sit on. Furthermore, because the armrest footrest structure 20 has a high height, the armrest footrest structure 20 can be used as a temporary table and the free footrest structure 10 can be used as a chair.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of this new model shall be subject to the scope of the attached patent application.
