Technology Field

[0001] The present disclosure relates to a guide device for a massage part and an opening / closing part that massages the cervical spine and the spine in a multifunctional smart bed. Background Technology

[0002] As sleep is a matter directly related to health, it is necessary to pay particular attention to the state of sleep. In addition, to provide 24-hour health management services, a device capable of checking and managing health status even during sleep may be required.

[0003] Wearable devices have been primarily used to monitor sleep status, and in the case of infants and toddlers, cameras and other devices are also used in addition to wearable devices for sleep monitoring.

[0004] However, in the case of wearable types, there is the inconvenience of attaching them to infants and toddlers, and there may be issues such as a foreign body sensation. Additionally, the structure and installation of the monitoring device may be complex and cumbersome.

[0005] Meanwhile, physical therapies that treat illnesses using electricity, light, and heat without the use of medicine have been widely practiced in both the East and the West. Recently, various types of physical therapy devices integrated with machinery have been developed and are in use, and among them, various types of treatment devices designed to treat the spine, the most critical part of the human body, have been developed and are being utilized.

[0006] Most therapeutic devices developed for the purpose of treating the spine are manufactured in the form of chairs or beds, allowing for even acupressure on the back or spine, while also enabling thermal physical therapy on the back or spine by adding heating devices as needed.

[0007] Among physical therapy devices used for the treatment of the back or spine, bed-type thermal therapy devices are equipped with thermal stimulation devices, such as electric heating devices, to move back and forth, thereby enabling even acupressure on the back or spine while simultaneously applying heat.

[0008] Massage is an auxiliary medical therapy that promotes blood circulation and relieves fatigue by kneading, pressing, pulling, tapping, or moving the body with hands or specialized tools. It regulates imbalances in muscles, joints, and internal organs to enhance their function and calms nerve excitement. Furthermore, massage is effective for insomnia, headaches, high blood pressure, circulatory disorders of blood and bodily fluids, physical functional abnormalities of muscles and joints, various types of neuralgia and sympathetic nervous system dysfunction, and the recovery of functional disorders of the digestive and urinary systems.

[0009] With the recent rise in interest in health, there has been a significant increase in interest in health aids, and consequently, automatic massage devices that allow users to receive massages on their own are becoming widely popularized.

[0010] Among such automatic massage devices, bed-type automatic massage devices are being produced that offer various convenient functionalities, such as the ability to massage the entire body or upper body while the user is lying flat, which is more comfortable and cozy than receiving a massage while sitting in a chair, and which allows the user's bent body to be massaged evenly.

[0074] According to one embodiment, the first guide rail (e.g., the guide rail (61) shown in FIG. 10) may further include a rack gear member joined along the longitudinal direction.

[0075] According to one embodiment, at least a portion of the massage portion (e.g., the massage portion (40) shown in FIG. 13) is provided with a moving force as the gear of the first drive motor meshes with at least a portion of the rack gear member, and at least a portion of the opening / closing portion (e.g., the opening / closing portion (50) shown in FIG. 12a) is provided with a moving force as the gear of the second drive motor meshes with at least a portion of the rack gear member.

[0076] According to one embodiment, each second guide rail (e.g., second guide rail (62, 63) shown in FIG. 10) may further include a guide recess (e.g., guide recess (620, 630) shown in FIG. 11) formed along the extended direction.

[0077] According to one embodiment, each guide recess (e.g., guide recess (620, 630) shown in FIG. 11) is spaced apart from the bottom structure (200), and each first and second guide roller can be accommodated in each guide recess (e.g., guide recess (620, 630) shown in FIG. 11).

[0078] In the present disclosure, "comprising at least one of a, b, or c" may mean "comprising only a, comprising only b, comprising only c, or comprising a combination of two or more (comprising a and b, comprising b and c, comprising a and c, or comprising all of a, b, and c)."
