Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, and in particular to a locker with a transformable ladder. Background Art

[0002] Ladders are essential items for every household and are often used when objects need to be replaced at the indoor roof. The common household ladders on the market are mostly folding ladders. When not in use, storing the ladder indoors not only occupies space but also is not aesthetically pleasing. Therefore, in the prior art, the combination of a cabinet and a ladder not only solves the problem of the ladder occupying space but also solves the problem of the single function of the cabinet.

[0003] For example, the Chinese patent with the patent number CN201520936592.8 discloses a ladder and a cabinet. The proposed ladder includes a frame body. On the vertical plate between the bottom plate and the top plate of the frame body, a ladder board with a width gradually decreasing from bottom to top is fixedly installed. On both sides of the frame body, a door panel is hinged through a rotating hinge. The same number of card slots as the number of ladder boards for clamping the ladder boards are provided on each door panel. The proposed cabinet includes two of the mentioned ladders. After one of the ladders is inverted, the bottom plate of the inverted ladder is connected to the top plate of the non-inverted ladder through a hinge. This ladder and cabinet achieve the rapid conversion between the ladder and the cabinet. At the same time, it is small in size and convenient to use, and can be placed in any corner of the room, saving space and maximizing the function.

[0004] However, when the cabinet is converted into a ladder in this patent, it is necessary to insert each ladder board into the card slot of the door panel, which takes a lot of time and effort and is not convenient to use.

[0005] Another example is the Chinese patent with the patent number CN201721158015.6, which discloses a storage cabinet with an extendable ladder, including a cabinet body. Inside the cabinet body, there are several partitions for placing items arranged from top to bottom. A frame body is slidably connected inside each partition, and the frame bodies are connected through a connecting piece slidably connected to the cabinet body. One side of the connecting piece is provided with a chute, which is embedded in the side of the partition, and waist-shaped notches are provided at both the upper and lower ends of the connecting piece. The frame body is in a U shape and is inverted downward on the partition. Transmission rods are alternately provided at the upper and lower ends of the side of the frame body. The transmission rod under the upper frame body and the transmission rod on the lower frame body are respectively inserted into the waist-shaped notches at both the upper and lower ends of the same connecting piece. A support plate for supporting the bottom cabinet body is also fixed below the frame body at the bottom of the cabinet body. In addition, universal wheels are provided in all four directions at the bottom of the cabinet body, and the universal wheels are respectively fixed below the bottom of the cabinet body and the support plate of the bottom frame body.

[0006] However, when the cabinet is converted into a ladder, the partitions need to be pulled open one by one, which is too cumbersome. At the same time, when the invention is used as a ladder, the accessible height is the same as when it is used as a cabinet, and it does not really achieve the climbing height required for conversion into a ladder.

[0007] The Chinese patent with the patent number CN201721158015.6 discloses a locker with a ladder, which is characterized in that the locker is cast into a rectangular parallelepiped consisting of three grids, and a groove is dug out on the locker frame, and the ladder can be embedded in the groove on the locker frame. When needed, people can take out the ladder on the locker for use, which saves space and is convenient and practical.

[0008] However, the patent only embeds the ladder in the frame of the locker, and does not realize the conversion between the locker and the ladder. Therefore, there are still problems of being unsightly and impractical.

[0009] Therefore, there is an urgent need for a piece of furniture with a simple structure that can realize rapid conversion of ladders and cabinets. Summary of the invention

[0010] In view of the deficiencies in the prior art, the present invention provides a locker with a convertible ladder. The locker and the ladder are converted by pushing and pulling, which is not only simple to convert but also has good stability.
