Description

Motion bed massage device

[0001] The present invention relates to a motion bed massage device, and more specifically, to a motion bed massage device that can recline the backrest without interference between the gears provided in the backrest and the seat by separating the gears provided in the backrest and the seat and protruding them outwardly, and by providing a cutout that is a space in which the gears can rotate.

[0002] Thermal massage devices are designed to alleviate acute or chronic pain occurring in the muscle and nerve tissues of the spine, and various types of spinal thermal massage devices are being developed recently.

[0003] The thermal massage device can move along parts of the body to improve blood circulation or relieve momentary muscle stiffness. Additionally, the heat generated by the thermal massage device can apply thermal stimulation to the painful area, thereby improving blood flow to the painful area and alleviating pain.

[0004] Conventional thermal massage devices have primarily utilized bed-type massage systems where the user lies down to receive a massage via a thermal massage module. Recently, in response to user demand, features allowing a portion of the bed-type massage unit to recline are being added. However, when adding a feature to reclin a part of the bed-type massage unit, the following problems may arise.

[0005] Conventional thermal massage devices used rails equipped with gears to move the thermal massage module. When a part of the bed-type massager is reclined, the gear equipped in the reclining part rotates, while the gear equipped in the fixed part remains stationary and fixed.

[0006] However, when reclining a portion of the bed-type massager, there is a risk of interference with surrounding parts due to the rotation radius of the rotating gear positioned in the reclining section. Additionally, there is a problem in forming a structure where the rotating gear and the fixed gear are connected while maintaining the path for the thermal massage module.

[0007] The structure in which the rotating gear provided in the reclining portion and the fixed gear provided in the fixed portion are connected can be omitted, and the rotating gear and the fixed gear can be completely separated. However, in this case, since the gear cannot be placed at the point where the reclining portion and the fixed portion are connected, there is a problem in that the thermal massage module is difficult to move smoothly.

[0008] The present invention is intended to solve the aforementioned problems, and more specifically, it relates to a motion bed massage device that can reclin the backrest without interference between the gears provided in the backrest and the seat by separating the gears provided in the backrest and the seat and protruding them outwardly, and by providing a cutout that is a space in which the gears can rotate.

Through this, gears extending from the seat part (110) to the backrest part (120) are arranged in two rows, thereby forming a certain width.

[0077] Referring to FIG. 5, a gap space (124) may be provided between one end of the seat portion (110) and the other end of the backrest portion (120). When the backrest portion (120) rotates relative to the seat portion (110), interference may occur between the backrest portion (120) and the seat portion (110) due to the rotation radius of the backrest portion (120). To prevent this, a gap space (124) may be provided between one end of the seat portion (110) and the other end of the backrest portion (120).

[0078] Additionally, according to an embodiment of the present invention, the point protruding outward from one end of the seat portion (110) at the first-2 extension portion (132) and the point protruding outward from the other end of the backrest portion (120) at the second-2 extension portion (142) can come into contact with each other in the spaced-out space (124). Through this, a gear can be placed at the point where the backrest portion (120) and the seat portion (110) are connected, allowing the thermal massage module (150) to move.

[0079] Referring to FIGS. 5 and 7, on the other side of the backrest portion (120) according to an embodiment of the present invention, a second cut portion (143) may be provided, which is an empty space adjacent to the second-2 extension portion (142).

[0080] The second cut section (143) may be formed parallel to the second-2 extension section (142). The second-1 extension section (141) may be extended to a second-1 width (c), and the second-2 extension section (142) may be extended to a second-2 width (d) which is smaller than the second-1 width (c). The second cut section (143) may be a space formed at a point where the width decreases, and the second cut section (143) is extended in the same direction as the second-2 extension section (142) and is positioned parallel to the second-2 extension section (142).

[0081] More specifically, the second-1 extension (141) can be arranged in two rows and the second-2 extension (142) can be arranged in one row, and the second incision (143) can be arranged parallel to the second-2 extension (142) arranged in one row to form one row.

[0082] In addition, on one side of the seat plate (110) according to an embodiment of the present invention, a first cut portion (133) consisting of an empty space adjacent to the first-second extension portion (132) may be provided.

[0083] The first cut section (133) may be formed parallel to the first-second extension section (132). The first-first extension section (131) may be extended to a first-first width (a), and the first-second extension section (132) may be extended to a first-second width (b) that is smaller than the first-first width (a). The first cut section (133) may be a space formed at a point where the width decreases, and the first cut section (133) is extended in the same direction as the first-second extension section (132) and is positioned parallel to the first-second extension section (132).

[0084] More specifically, the first-1 extension (131) can be arranged in two rows and the first-2 extension (132) can be arranged in one row, and the first cut (133) can be arranged parallel to the first-2 extension (132) arranged in one row to form one row.

[0085] As described above, when the seat portion (110) and the backrest portion (120) are arranged flat, the first-2 extension portion (132) protruding outward from one end of the seat portion (110) and the second-2 extension portion (142) protruding outward from the other end of the backrest portion (120) can be brought into contact.

[0086] When the seat portion (110) and the backrest portion (120) are arranged flat, and the backrest portion (120) reclines as shown in FIG. 3, a space is required for the first-2 extension portion (132) and the second-2 extension portion (142) to rotate. The second cut portion (143) and the first cut portion (133) can provide a space for the first-2 extension portion (132) and the second-2 extension portion (142) to rotate.

[0087] Referring to FIGS. 7 and 8, when the backrest portion (120) rotates relative to the seat portion (110), the first-second extension portion (132) can be inserted into the second cut portion (143), and the second-second extension portion (142) can be inserted into the first cut portion (133).

[0088] Through this, when the backrest portion (120) rotates relative to the seat portion (110), the backrest portion (120) can rotate relative to the seat portion (110) without interference occurring between the first gear (130) and the second gear (140).

[0089] More specifically, by providing a space through the second cut section (143) and the first cut section (133) through which the first-2 extension section (132) and the second-2 extension section (142) can rotate, the first gear (130) and the second gear (140) can be separated without interference between the first gear (130) and the second gear (140). This allows the path through which the thermal massage module (150) can move to be separated.

[0090] Afterward, when the seat portion (110) and the backrest portion (120) are flattened, the first-second extension portion (132) and the second-second extension portion (142) can come into contact with each other. Through this, the path along which the thermal massage module (150) can move can be integrated.

[0091] Referring to FIG. 9, the thermal massage module (150) may be movable when the seat portion (110) and the backrest portion (120) are arranged flat.
