Description

Lifting aid

The present invention relates to a lifting aid, and more particularly to a lifting aid that is inclined in the lifting direction and combined with a movable base.

The lifting aid is a product for the elderly who are disabled or whose mobility is degraded. Among these products, one type is a rigid bracket installed on the lower limbs of the user (such as the inner side of the leg), and the metal and the like are used to share the muscle and bone load, thereby slowly supporting the body. Most of these products are suitable for rehabilitation treatments for temporary injuries. Their main function is to assist the injury and to avoid secondary damage caused by excessive load. It is not designed to support the user's total weight. That is to say, the above products still have a certain degree of requirement for the physical strength of the user, and the product group of the product does not match the person with weak physical condition.

Therefore, for elderly people with osteoporosis, rheumatoid arthritis, and sarcopenia, the above-mentioned types of auxiliary devices are obviously not effective. In recent years, some people have developed an auxiliary device that can provide extra power, and the bottom-up thrust can help the elderly to get up easily.

However, since the above products require high power, such devices are often fixedly placed on indoor walls and the like, and are similar to the user's dedicated seats. According to these setting conditions, the lifting aid can only provide a fixed-point function, and the elderly must prepare the walking device with them, so that they can move themselves after getting up, which is inconvenient to use.

In addition, the general lifting aid only considers the posture of the human body when standing upright, so the lifting direction is vertical lifting, but this design does not consider that the trajectory of the human body when changing from the sitting posture to the standing posture is not a straight line, and the user is subjected to the use during use. All kinds of discomfort.

Therefore, in order to overcome the deficiencies of the prior art, the present invention proposes a lifting aid that combines the lifting mechanism with the movable base to facilitate user operation. In addition, the lifting mechanism is moved obliquely to assist the user to naturally switch between standing and sitting.

According to one embodiment of the present invention, a lift assist device is provided. The lifting aid includes a base, a lifting mechanism, and a fixing unit. The pedestal stands on the ground and the lifting mechanism is located on the pedestal. The lifting mechanism reciprocates along a lifting direction. The fixing unit is connected to the lifting mechanism and is interlocked, and the fixing unit is fixed to the limb of the user. The extension line of the aforementioned lifting direction is not perpendicular to the ground.

According to the above embodiment, the present invention can integrate the base into a product such as a walker, thereby providing the lifting aid with the advantages of being used anywhere. Since the moving direction of the lifting mechanism is not vertical, the user will be more comfortable and smooth during the switching between the sitting posture and the standing posture.

The angle between the extension line of the lifting mechanism and the ground in the lifting direction may be less than or equal to 70 degrees.

In an embodiment, the lifting aid further includes a plurality of movable wheels disposed at the bottom of the base for the base to move relative to the ground.

In an embodiment, the lift-up aid further includes a power unit that is coupled to the lift mechanism to provide lift power thereto. The power unit may be in the form of electric drive, hydraulic drive or pneumatic drive, but is not limited thereto.

In addition, the lifting aid may also include a plurality of wires, each of which is used to connect the movable wheel and is connected to the power unit. By means of wire connections, the power unit can be rotated by the power control activity wheel. Thereby, the user can use the power device to move from the remote remote control assisting device without pushing, moving or accommodating with human power.

In this way, for a group of elderly people with a weaker physical function, the movable wheel and the power device can enhance the auxiliary functions during movement and lifting, so that the user can move freely.

In an embodiment, the aforementioned fixing unit may be a rope, a belt, a cloth, a grip or a fastener.

In an embodiment, the lift-up aid further includes a support unit that connects the lift mechanism. The reliant unit can be additionally installed. For example, the reliant unit can be pivotally connected to the lifting mechanism for easy disassembly or storage. Further, the fixing unit may indirectly connect the elevating mechanism through the retracting unit.
