Description

Technical Field

[0001] This utility model relates to a mattress lifter, belonging to the technical field of mattress lifting equipment. Background Technology

[0002] As people's living standards improve, their requirements for sleep environments are also constantly increasing, leading to the widespread use of heavy mattresses in the market. However, when changing and making bed sheets, the weight of the mattress can be a problem, often requiring considerable strength to lift even a small section of the mattress, especially for the elderly, those with weak constitutions, or those whose arms or backs are not supported.

[0003] Currently, some lifting tools on the market, such as wedge tools, do not save effort and require force to push them under the mattress; L-shaped pry bars, for example, have sharp points that can scratch and damage the mattress, and when the bed frame and mattress are the same size, it is difficult to find a point of leverage; and insert boards can only be used to stuff sheets and do not have the function of lifting heavy mattresses. Therefore, there is an urgent need for a lifting tool that saves effort and will not damage the mattress. Utility Model Content

[0004] To solve the above problems, this utility model provides a mattress lifter, comprising: handle; A base plate, connected to the handle, wherein a roller assembly is provided on one side edge of the base plate; When the base plate is inserted into the gap between the mattress and the bed frame, a lever structure that lifts the mattress can be formed by rotating the handle, using the side of the base plate relative to the roller assembly as a fulcrum.

[0005] Furthermore, the handle includes a hand-held portion and a connecting arm that connects the hand-held portion and the base plate.

[0006] Furthermore, the substrate is a quasi-right trapezoidal plate, with an arc-shaped smooth transition portion provided at its acute angle.

[0007] Furthermore, a roller assembly is provided on the beveled edge of the substrate.

[0008] Furthermore, a fastening member is provided at the connection between the top bottom edge and the right-angled edge of the substrate, and one end of the connecting arm is assembled into the fastening member along the plane of the substrate.

[0009] Furthermore, a fixing hole is provided in the middle of the right-angled side of the substrate, and one end of the connecting arm is fitted into the fixing hole in a direction perpendicular to the plane of the substrate.

[0010] Furthermore, the substrate surface is provided with a plurality of grid-like grooves arranged in an array.

[0011] Furthermore, the roller assembly includes a pin fixed along one edge of the substrate and a roller mounted on the pin, with bearings provided on both sides of the roller.

[0012] The beneficial effects of this utility model are: This invention creates a mattress lifter by incorporating a handle, a base plate, and a roller assembly on the base plate to convert sliding friction into rolling friction. This significantly reduces friction between the lifter and the mattress during operation. The roller assembly and other parts of the mattress lifter have curved contact surfaces with the mattress, which not only reduces friction but also prevents scratching and damage. Furthermore, the use of a long, narrow handle connecting arm further enhances the effort-saving effect. Attached Figure Description

[0015] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Specifically, the terms "first position" and "second position" refer to two different positions.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] This utility model provides a mattress lifter, including a handle 1 and a base plate 2 connected to the handle 1. A roller assembly 3 is provided on the base plate 2, wherein: In some embodiments, the handle 1 includes a handgrip 11 and a connecting arm 12 connecting the handgrip 11 and the substrate 2. In the examples of Figures 1-5, the handgrip 11 is a cylindrical component that is easy for a person to hold, and its surface can be provided with a certain curvature to adapt to the posture of a person holding it, forming an ergonomic shape structure; the connecting arm 12 is a long rod structure, the length of which can be adjusted according to actual needs, or it can be set as a telescopic rod, mainly used to connect the substrate 2 and provide torque. In some embodiments, the handle 1 can also be a handle, pull ring, or other structures.

[0019] In some embodiments, the substrate 2 is connected to the handle 1, and a roller assembly 3 is provided on one side edge of the substrate 2.

[0020] In the examples shown in Figures 1-5, the substrate 2 is a near-right-angled trapezoidal plate, which provides stability during support. It can also be configured with other irregular plate shapes. Its acute-angled portions have rounded transition sections 21, effectively reducing friction and preventing rubbing against the mattress. Furthermore, the surface of the substrate 2 is provided with multiple arrayed grid-like grooves, achieving a lightweight design while also providing a surface anti-slip effect.

[0021] Furthermore, a roller assembly 3 is provided on the inclined side of the substrate 2. In the example of Figures 3-4, the roller assembly 3 includes a pin 32 fixed along one edge of the substrate 2 and a roller 31 mounted on the pin 32. Bearings 33 are also provided on both sides of the roller 31. When the roller 31 touches the mattress, rolling friction is generated, avoiding damage caused by sliding friction.

[0022] Example 1 This embodiment provides an assembly method for the handle 1 and the substrate 2: they are disposed in the same plane.

[0023] A fastening member 22 is provided at the connection between the top bottom edge and the right-angled edge of the substrate 2. One end of the connecting arm 12 is assembled into the fastening member 22 along the plane of the substrate 2. After such connection, the handle 1 and the substrate 2 are approximately in the same plane.

[0024] When the base plate 2 is inserted into the gap between the mattress and the bed frame, a lever structure for lifting the mattress can be formed by rotating the handle 1, with the other side of the base plate 2 relative to the roller assembly 3 as the fulcrum.

[0025] Example 2 This embodiment provides another method for assembling the handle 1 and the substrate 2: they are arranged in mutually perpendicular planes.

[0026] A fixing hole is provided in the middle of the right-angled side of the substrate 2, and one end of the connecting arm 12 is fitted into the fixing hole in a direction perpendicular to the plane of the substrate 2.
