Abstract

[Problem] To provide an attachment and massage device that can be attached to a massage machine to perform massages other than percussive massage. [Solution] The attachment 31 is used in a massage machine 11 equipped with a reciprocating body 13 that moves linearly back and forth to perform a tapping massage on the part of the user to be treated. The attachment 31 comprises a treatment body 33 and a conversion mechanism 34 that converts the reciprocating motion of the reciprocating body 13 into rotational motion of the treatment body 33.

Description

This invention relates to an attachment for a massage machine and a massage device. Patent Document 1 discloses a handheld massage machine that the user holds in their hand to massage the area to be treated. This massage machine includes a massage member that extends and retracts from a head section, a drive motor that drives the massage member, and a conversion mechanism that converts the rotational motion of the drive motor's output shaft into the extension and retraction motion of the massage member. Japanese Patent Publication No. 2002-282322 This is a perspective view of a massage device including an attachment and a massage machine according to an embodiment.This is a perspective view of a massage machine with the attachment removed.This is a front view of the massage device.This is a cross-sectional view of a massage device.This is a perspective view of the inside of a massage machine.This is a perspective view of the attachment conversion mechanism and the treatment body.This is a disassembled perspective view of the attachment conversion mechanism and the treatment body.This is a rear view illustrating the operation of the attachment conversion mechanism. Embodiments of this disclosure will be described below with reference to the drawings. Figure 1 is a perspective view of a massage device including an attachment and a massage machine according to an embodiment. Figure 2 is a perspective view of the massage device with the attachment removed from the massage machine. Figure 3 is a front view of the massage device. Figure 4 is a cross-sectional view of the massage device. As shown in Figures 1 and 2, the massage device 10 of this embodiment is constructed by attaching an attachment 31 to a massage machine 11. In other words, the massage device 10 includes a massage machine 11 and an attachment 31. The massage machine 11 performs a massage on the user independently. Specifically, the massage machine 11 in this embodiment performs a "tapping massage" on the user. In contrast, the attachment 31 is attached to the massage machine 11 and uses the power of the massage machine 11 to perform a massage on the user. The attachment 31 performs a different type of massage than the tapping massage performed by the massage machine 11. Specifically, the attachment 31 in this embodiment performs a "rubbing, kneading, or kneading massage." (Configuration of massage machine 11) As shown in Figures 2 to 4, the massage machine 11 comprises a casing 12, a treatment body 13, and a drive mechanism 14. The casing 12 constitutes the outer shell of the massage machine 11. The casing 12 is made of synthetic resin, metal, or the like. The casing 12 includes a handle portion 12a and a head portion 12b. The handle portion 12a is formed in a slightly rounded cylindrical shape. The handle portion 12a is sized (length and thickness) to be easily grasped by the user with one hand. The head portion 12b is also cylindrical and protrudes from the outer surface of the handle portion 12a. Therefore, the handle portion 12a and the head portion 12b are in an intersecting relationship. When the longitudinal direction of the handle portion 12a is oriented vertically, the head portion 12b protrudes approximately horizontally from the handle portion 12a. Therefore, the handle portion 12a and the head portion 12b are perpendicular to each other. The handle 12a is equipped with an operation button 12d. This operation button 12d allows for at least one of the following actions: turning the massager 11 on and off, turning the massage function on and off, and switching the massage intensity. In the following description, the direction in which the longitudinal direction of the handle portion 12a faces is defined as the up-down direction, and the direction in which the head portion 12b faces (the direction along the cylindrical center line C1 of the head portion 12b (see Figures 3 and 4)) is defined as the front-back direction. Furthermore, the head portion 12b is assumed to protrude forward from the handle portion 12a. In the following description, the left-right direction refers to the left-right direction as viewed from the user holding the handle portion 12a and pointing the head portion 12b forward (see Figure 3). However, these directions are merely illustrative and do not limit the present invention. Therefore, the up-down direction, front-back direction, and left-right direction can be reinterpreted as mutually orthogonal "first direction," "second direction," "third direction," etc., and each direction such as up, down, front, back, left, right can be reinterpreted as "one side" and "the other side" of the first to third directions. The head portion 12b is positioned slightly above the vertical center of the handle portion 12a. For example, the center line C1 of the head portion 12b is located within a range of 3/5 to 2/3 of the vertical length of the handle portion 12a from the lower end of the handle portion 12a. Therefore, the user can
