Description

Household Lifting Device The present invention relates to a household lift device, and in particular, to a household lift device that allows a user to easily and safely lift household items to a specific height by hand without the need for additional power. Generally, it is difficult for housewives and the elderly to lift relatively heavy household items vertically at home, and there is a risk of safety accidents occurring during the process of lifting household items. In particular, elderly people, female housewives, and the elderly with weak muscles may develop conditions such as herniated discs or fractures while moving these household items vertically. In order to solve such problems, an electric lift capable of adjusting the height of a loading platform on which goods are loaded has been developed in the past, according to registered patent 10-1846855, an electric lift device (registration date April 3, 2018). The above-described electric lift device comprises a motor that generates driving force through the supply of electricity, a power transmission unit connected to the motor that moves along the inner surface of a fixed frame placed on the floor via the motor's driving force and presses an X-shaped scissor frame to adjust the height of the scissor frame, a loading platform placed on the top of the scissor frame capable of loading goods, and a switch connected to the motor that controls the operation of the motor through the operator's manipulation. However, conventional electric lift devices require power, making them unusable in environments where power supply is difficult. Additionally, since the user must check the height of the items loaded on the platform and adjust the platform height, moving and unloading items takes a long time, and the complex structure results in high production costs. FIG. 1 is a cross-sectional view of a household lift device according to an embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating the operation of a household lift device according to an embodiment of the present invention. Figure 3 is an enlarged view of section 'A' of Figure 1. FIG. 4 is a side view showing the winding unit, pulley, and handle illustrated in FIG. 1. The present invention described below is capable of various modifications and may have various embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In describing the invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the invention. The terms used in this patent are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this patent, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Additionally, terms such as "first," "second," etc., may be used to distinguish and describe various components, but said components shall not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. In addition, if at least two different embodiments are described in this patent, each embodiment may use all or part of its components in combination and mixed with one another without further description, as long as it does not deviate from the technical concept of the present invention. FIG. 1 is a cross-sectional view of a household lift device according to an embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating the operation of a household lift device according to an embodiment of the present invention. FIG. 3 is an enlarged view of section 'A' of FIG. 1. FIG. 4 is a side view showing a winding unit, a pulley, and a handle as depicted in FIG. 1. Referring to FIGS. 1 to 4, a household lift device (100) includes a lift body (10), a wheel (20), a handle member (30), a link member (40), a base (50), a wire (60), and a winding unit (70). The lift body (10) is formed in a flat plate shape, and the lift body (10) can be formed in a square flat plate shape, for example.
