Inside the housing 17, there is provided a width adjusting means 15 for moving the massaging member 14 in the horizontal direction.

一般而言，使用者的肩寬(肩部的左右方向的寬度)窄可以說是身高較矮。也就是說，由於就座於座部2之使用者的座高變低，所以為了配合該使用者的體型，必須將左右一對的按摩構件14降低至肩部的位置，以調整左右的間隔。 於是，本發明的寬度調整手段15為了配合身材短小之使用者的體型，作成一邊將左右一對的按摩構件14的間隔縮小一邊使之往斜下方移動。In general, a narrow shoulder width (width of the shoulders in the left-right direction) of a user can be said to be short in height. That is, since the seat height of the user sitting on the seat 2 becomes lower, in order to fit the user's body shape, the pair of left and right massage members 14 must be lowered to the position of the shoulders to adjust the left and right spacing. Therefore, the width adjusting means 15 of the present invention is made to move diagonally downward while narrowing the interval between the pair of left and right massage members 14 in order to match the body shape of a user with a short stature.

寬度調整手段15係設置於右側的按摩構件14a的基端及左側的按摩構件14b的基端之每一者。 寬度調整手段15係在將左右一對的按摩構件14的間隔變窄時，一邊使按摩構件14往左右方向(靠背部3的內側)移動，一邊使之往斜下方擺動。 此外，本實施形態中，將左右一對的按摩構件14的間隔最廣的狀態設為按摩構件14(寬度調整手段15)的通常狀態。亦即，左右一對的按摩構件14通常在最打開的狀態下待機。The width adjusting means 15 is provided in each of the base end of the right massage member 14a and the base end of the left massage member 14b. The width adjusting means 15 moves the massage member 14 in the left-right direction (inside the backrest 3) and swings it diagonally downward when the interval between the pair of left and right massage members 14 is narrowed. In addition, in this embodiment, the state where the space|interval of the pair of left and right massage members 14 is widest is made into the normal state of the massage member 14 (width adjustment means 15). That is, the pair of left and right massage members 14 usually stand by in the most opened state.

具體而言，右側的寬度調整手段15a係一邊使右側的按摩構件14a往左方移動，一邊往左斜下方擺動。又，左側的寬度調整手段15b係一邊使左側的按摩構件14b往右方移動，一邊往右斜下方擺動。 另一方面，寬度調整手段15係在將左右一對的按摩構件14的間隔擴展(返回通常狀態)時，一邊使按摩構件14往左右方向(靠背部3的外側)移動，一邊往斜上方擺動。Specifically, the width adjustment means 15a on the right side moves the massaging member 14a on the right side to the left while swinging diagonally downward to the left. In addition, the width adjustment means 15b on the left side swings the massage member 14b on the left side diagonally downward to the right while moving the massage member 14b on the left side. On the other hand, when the width adjusting means 15 expands the interval between the pair of left and right massage members 14 (returns to the normal state), the massage member 14 is moved in the left-right direction (outside the backrest 3) while swinging diagonally upward. .

具體而言，右側的寬度調整手段15a係一邊使右側的按摩構件14a往右方移動，一邊往右斜上方擺動。又，左側的寬度調整手段15b係一邊使左側的按摩構件14b往左方移動，一邊往左斜上方擺動。 亦即，寬度調整手段15係作成配合使用者的肩寬，一邊使按摩構件14往左右方向移動，一邊往斜下方及斜上方擺動，以在既定的位置固定，藉此調整按摩構件14的左右間隔之構成。Specifically, the width adjustment means 15a on the right side moves the massaging member 14a on the right side to the right and swings diagonally upward to the right. In addition, the width adjusting means 15b on the left side moves the massage member 14b on the left side to the left while swinging diagonally upward to the left. That is, the width adjustment means 15 is made to fit the user's shoulder width, while moving the massage member 14 in the left and right directions, while swinging diagonally downward and diagonally upward, to be fixed at a predetermined position, thereby adjusting the left and right sides of the massage member 14 The composition of the interval.

本實施形態中，寬度調整手段15係作成可將左右一對的按摩構件14的間隔階段性地進行調整之棘輪機構。 此處係著眼於右側的寬度調整手段15a，來說明裝置構成。此外，左側的寬度調整手段15b係與右側的寬度調整手段15a呈鏡像配置，關於裝置構成係大致相同。亦即，由於右側的寬度調整手段15a與左側的寬度調整手段15b係成為左右對稱，故省略左側的寬度調整手段15b的說明。In this embodiment, the width adjustment means 15 is a ratchet mechanism which can adjust the interval of the pair of left and right massage members 14 in stages. Here, focusing on the width adjustment means 15a on the right side, the device configuration will be described. In addition, the width adjustment means 15b on the left side and the width adjustment means 15a on the right side are arranged in a mirror image, and the device configuration is substantially the same. That is, since the width adjusting means 15a on the right and the width adjusting means 15b on the left are bilaterally symmetrical, the description of the width adjusting means 15b on the left is omitted.

圖4～圖7係將右側的寬度調整手段15a予以放大之圖。 首先，如圖4、圖5所示，在靠背框架6設有供載置寬度調整手段15a之載置板18。此載置板18係在往右方傾斜狀態下設置於靠背框架6。又，在按摩構件14a的基端，設置有支撐該按摩構件14a之支撐構件19。支撐構件19係作成三角形狀的筒構件，以斜邊成為垂下狀的方式配備。4 to 7 are enlarged views of the width adjusting means 15a on the right side.

The mounting plate 18 is installed on the back frame 6 in a state of being inclined to the right. In addition, a support member 19 for supporting the massage member 14a is provided at the base end of the massage member 14a. The support member 19 is a triangular cylindrical member, and it is equipped so that the oblique side may hang down.

右側的寬度調整手段15a係安裝於靠背框架6的右側邊所設置之載置板18。亦即，右側的寬度調整手段15a係在朝右方外側傾斜的狀態下，配備在靠背框架6的右側邊。 如圖6、圖7所示，寬度調整手段15a係安裝於按摩構件14a的基端，具有：擺動部20，使該按摩構件14a往斜下方及斜上方擺動；支撐部21，安裝於靠背框架6，將擺動部20以擺動自如的方式支撐；以及卡合部22，將擺動部20卡合於該支撐部21。The width adjusting means 15a on the right side is attached to the mounting plate 18 provided on the right side of the back frame 6. That is, the width adjusting means 15a on the right side is provided on the right side of the backrest frame 6 in a state inclined to the outside to the right. As shown in Figures 6 and 7, the width adjusting means 15a is installed on the base end of the massage member 14a, and has: a swing part 20 to swing the massage member 14a obliquely downward and obliquely upward; a support part 21 installed on the backrest frame 6. The swing part 20 is supported in a swingable manner; and the engaging part 22 engages the swing part 20 with the support part 21.

支撐部21係由在前後方向呈長形的矩形構件形成。在支撐部21的後側上部，形成有軸心相對於前後方向，朝向大致左右方向的貫通孔23。在此貫通孔23，***有支撐軸24，其係將擺動部20以擺動自如的方式支撐。 此外，支撐軸24(貫通孔23)係以當支撐部21安裝於載置板18時，軸心會與朝右方外側傾斜的載置板18平行之方式設置。又，繞著貫通孔23安裝有彈簧29(例如捲繞彈簧)，其係產生反作用力以賦予至擺動部20。The supporting portion 21 is formed of a rectangular member that is elongated in the front-rear direction. In the upper portion of the rear side of the support portion 21, a through hole 23 whose axis is oriented in a substantially left-right direction with respect to the front-rear direction is formed. In the through hole 23, a support shaft 24 is inserted to support the swing portion 20 in a swingable manner. In addition, the support shaft 24 (through hole 23) is installed in such a way that when the support portion 21 is mounted on the mounting plate 18, the shaft center is parallel to the mounting plate 18 inclined outward to the right. In addition, a spring 29 (for example, a winding spring) is attached around the through hole 23 and generates a reaction force to be applied to the swing portion 20.

又，支撐部21係分割於大致左右方向之構件，於其間挾持有板構件25。於板構件25形成有貫通孔(未圖示)，且嵌入有支撐軸24。板構件25係使繞著貫通孔23(支撐軸24)而安裝的捲繞彈簧29扭轉，以產生反作用力之構件。亦即，板構件25係藉由捲繞彈簧29的作用(反作用力)而在與擺動部20相反方向旋轉之反轉(counter)構件。In addition, the support portion 21 is a member that is divided substantially in the left-right direction, and the plate member 25 is sandwiched therebetween. A through hole (not shown) is formed in the plate member 25, and the support shaft 24 is fitted. The plate member 25 is a member that twists the coil spring 29 installed around the through hole 23 (support shaft 24) to generate a reaction force. That is, the plate member 25 is a counter member that rotates in the opposite direction to the swinging portion 20 by the action (reaction force) of the winding spring 29.

在支撐部21的前側上部，形成有構成卡合部22(詳情係於後述)的階段狀卡合凸部31。 擺動部20係隔介支撐構件19設於按摩構件14a的基端。此外，擺動部20係被覆蓋體所覆蓋，並隔介該覆蓋體安裝於支撐構件19，但並未圖示。On the upper part of the front side of the support portion 21, a step-shaped engaging convex portion 31 constituting the engaging portion 22 (details will be described later) is formed. The swing portion 20 is provided at the base end of the massage member 14a via the supporting member 19. In addition, the swing part 20 is covered by a covering body, and is attached to the supporting member 19 via the covering body, but it is not shown in the figure.

擺動部20係前後及下方形成有開口之前後方向為長形的隧道(tunnel)狀構件。亦即，擺動部20係形成大致ㄈ字狀的構件，且係以覆蓋支撐部21的方式配備的構件。此外，擺動部20係以在配備於靠背框架6的右側邊時，下方的開口朝向左斜下方的方式設置。 在擺動部20的後側上部，形成有軸心相對於前後方向，朝向大致左右方向的貫通孔26。此貫通孔26的軸心係與支撐部21的貫通孔23的軸心一致。亦即，使擺動部20之貫通孔26的軸心、與支撐部21之貫通孔23的軸心一致後，支撐軸24以旋轉自如的方式被***。在擺動部20的後側下部，卡合有繞著支撐部21的貫通孔23而安裝之捲繞彈簧29的前端。The swing portion 20 is a tunnel-shaped member having an opening in the front and rear directions that is long in the front and rear directions. That is, the swing portion 20 is a member formed in a substantially U shape and is a member provided so as to cover the support portion 21. In addition, when the swing portion 20 is provided on the right side of the backrest frame 6, the lower opening is provided diagonally downward to the left. On the upper rear side of the swinging portion 20, a through hole 26 whose axis is oriented in a substantially left-right direction with respect to the front-rear direction is formed. The axis of the through hole 26 coincides with the axis of the through hole 23 of the support portion 21. That is, after the axis of the through hole 26 of the swinging portion 20 is aligned with the axis of the through hole 23 of the support portion 21, the support shaft 24 is rotatably inserted. At the lower part of the rear side of the swinging portion 20, the front end of the winding spring 29 installed around the through hole 23 of the supporting portion 21 is engaged.

於此擺動部20設置有彈簧29(例如捲繞彈簧)，其係在將按摩構件14a朝外側打開的方向上賦予反作用力。 當使擺動部20繞著支撐軸24朝座部2的外側擺動時，擺動部20係相對於支撐部21的板構件25旋轉，卡合於擺動部20的捲繞彈簧29被扭轉，捲繞彈簧29反彈。藉此，設成按摩構件14a欲返回通常狀態。Here, the swing portion 20 is provided with a spring 29 (for example, a winding spring), which is to provide a reaction force in a direction to open the massage member 14a to the outside. When the swing portion 20 is swung toward the outside of the seat portion 2 around the support shaft 24, the swing portion 20 rotates relative to the plate member 25 of the support portion 21, and the winding spring 29 engaged with the swing portion 20 is twisted and wound The spring 29 rebounds. Thereby, it is assumed that the massage member 14a is about to return to the normal state.

反之，當使擺動部20繞著支撐軸24朝座部2的內側擺動時，擺動部20會成為相對於支撐部21的板構件25旋轉，卡合於擺動部20的捲繞彈簧29朝逆向被扭轉，捲繞彈簧29變成收縮。藉此，右側的按摩構件14a往左斜下方移動。 亦即，當擺動部20朝打開的方向(按摩構件14a擴展的方向)移動時，板構件25便藉由繞著支撐軸24所安裝的捲繞彈簧29的反作用力，與擺動部20逆向(遠離的方向)地移動。Conversely, when the swing portion 20 is swung toward the inside of the seat portion 2 around the support shaft 24, the swing portion 20 rotates relative to the plate member 25 of the support portion 21, and the winding spring 29 engaged with the swing portion 20 turns in the reverse direction Being twisted, the coil spring 29 becomes contracted. Thereby, the massage member 14a on the right side moves diagonally downward to the left. That is, when the swinging portion 20 moves in the opening direction (the direction in which the massage member 14a expands), the plate member 25 counteracts the swinging portion 20 by the reaction force of the winding spring 29 installed around the support shaft 24 ( Away) to move.

另一方面，在擺動部20的前側上部，形成有軸心相對於前後方向，朝向大致左右方向的貫通孔27。在此貫通孔27，嵌入有將卡合片35(詳情係如後述)以轉動自如的方式支撐之旋轉軸28。 此外，當旋轉軸28(貫通孔27)配備在靠背框架6的右側邊時，係以軸心與朝向右方向外側傾斜的載置板18平行之方式設置。又，在此旋轉軸28，安裝有會產生反作用力之捲繞彈簧30。On the other hand, in the upper part of the front side of the swinging portion 20, a through hole 27 is formed whose axis is directed substantially in the left and right direction with respect to the front and rear direction. Here, the through hole 27 is fitted with a rotating shaft 28 that rotatably supports the engaging piece 35 (details will be described later). In addition, when the rotation shaft 28 (through hole 27) is provided on the right side of the back frame 6, it is provided so that the shaft center is parallel to the mounting plate 18 inclined toward the outside in the right direction. In addition, the rotating shaft 28 is equipped with a coil spring 30 that generates a reaction force.

卡合部22具有︰設置於支撐部21之卡合凸部31；及設置於擺動部20，且嵌入卡合於卡合凸部31之卡合凹部32。 卡合凸部31係在支撐部21的前側上部設有複數個，卡合凹部32嵌入於卡合凸部31的任一者，藉此構成為調整左右一對的按摩構件14在左右方向的間隔。The engaging portion 22 has: an engaging convex portion 31 provided on the supporting portion 21; and an engaging concave portion 32 provided on the swinging portion 20 and inserted and engaged with the engaging convex portion 31. The engaging convex portion 31 is provided on the upper part of the front side of the supporting portion 21, and the engaging concave portion 32 is fitted into any one of the engaging convex portions 31, thereby being configured to adjust the left-right pair of massage members 14 in the left-right direction interval.

如圖7所示，卡合凸部31係作成以大致L字形狀，朝前方呈弧形突出的構件。又，在卡合凸部31，設有第1卡合面33和第2卡合面34。 第1卡合面33係朝向左斜下方且朝向後方的面。此第1卡合面33係與設置在卡合凹部32的第1卡合面37形成面接觸。As shown in Fig. 7, the engaging convex portion 31 is formed into a substantially L-shaped member that protrudes in an arc shape toward the front. In addition, the engagement convex portion 31 is provided with a first engagement surface 33 and a second engagement surface 34. The first engagement surface 33 is a surface that faces diagonally downward to the left and backward. The first engagement surface 33 is in surface contact with the first engagement surface 37 provided in the engagement recess 32.

第2卡合面34係朝向與第1卡合面33所面向的方向大致正交的方向(右斜上方且後方)之面。此第2卡合面34係與設置在卡合凹部32的第2卡合面38形成面接觸。 本實施形態中，卡合凸部31係以複數個山相連的方式，形成有三個的階段狀溝部。換言之，卡合凸部31可以說從側面看起來為形成有三個屋檐狀凸部之構件。The second engagement surface 34 is a surface that faces in a direction (obliquely upward to the right and rear) substantially orthogonal to the direction in which the first engagement surface 33 faces. This second engagement surface 34 is in surface contact with the second engagement surface 38 provided in the engagement recess 32. In the present embodiment, the engaging convex portion 31 is formed with three step-shaped groove portions such that a plurality of mountains are connected. In other words, the engaging convex portion 31 can be said to be a member formed with three eave-shaped convex portions when viewed from the side.

卡合片35係形成為平坦狀的構件，且安裝於擺動部20的前側。在此卡合片35的後側，形成有與卡合凸部31卡合之卡合凹部32。 如圖7所示，卡合凹部32係作成大致L字形狀，且朝後方向像谷那樣凹陷的面。又，在卡合凹部32，設置有第1卡合面37和第2卡合面38。The engaging piece 35 is a member formed in a flat shape, and is attached to the front side of the swing portion 20. On the rear side of the engagement piece 35, an engagement recess 32 that engages with the engagement protrusion 31 is formed. As shown in FIG. 7, the engagement recessed part 32 is formed in a substantially L-shape, and is a recessed surface like a valley in the rear direction. In addition, the engagement recessed portion 32 is provided with a first engagement surface 37 and a second engagement surface 38.

第1卡合面37係朝向左斜下方且朝向後方的面。此第1卡合面37係與設置在卡合凸部31的第1卡合面33形成面接觸。 第2卡合面38係朝向與第1卡合面37所面向的方向大致正交的方向(右斜上方且後方)之面。此第2卡合面38係與設置在卡合凸部31的第2卡合面34形成面接觸。The first engagement surface 37 is a surface that faces diagonally downward to the left and backward. The first engagement surface 37 is in surface contact with the first engagement surface 33 provided on the engagement protrusion 31. The second engaging surface 38 is a surface facing in a direction (obliquely upward and rearward to the right) substantially orthogonal to the direction in which the first engaging surface 37 faces. This second engaging surface 38 is in surface contact with the second engaging surface 34 provided on the engaging convex portion 31.

亦即，谷狀的卡合凹部32係與形成於支撐部21之山形狀的卡合凸部31無間隙地面接觸，而成為嵌合的部位。此外，谷狀的卡合凹部32和山形狀的卡合凸部31具有大致相同的面積。 另一方面，在卡合片35的前側，形成有軸心相對於前後方向，朝向大致左右方向的貫通孔36。此貫通孔36的軸心係與形成於擺動部20的前側之貫通孔27的軸心一致。亦即，使卡合片35之貫通孔36的軸心與擺動部20之貫通孔27的軸心一致後，旋轉軸28以可旋轉自如的方式被***。此卡合片35成為繞著旋轉軸28旋轉。That is, the valley-shaped engagement recesses 32 are in contact with the mountain-shaped engagement protrusions 31 formed on the support portion 21 on the ground without a gap, and become a fitting portion. In addition, the valley-shaped engagement recesses 32 and the mountain-shaped engagement protrusions 31 have substantially the same area. On the other hand, on the front side of the engagement piece 35, a through hole 36 whose axis is oriented substantially in the left-right direction with respect to the front-rear direction is formed. The axis of the through hole 36 is consistent with the axis of the through hole 27 formed on the front side of the swing portion 20. That is, after the axis of the through hole 36 of the engaging piece 35 is aligned with the axis of the through hole 27 of the swing portion 20, the rotating shaft 28 is rotatably inserted. This engaging piece 35 rotates around the rotating shaft 28.

又，在繞著卡合片35的旋轉軸28，設置有當卡合凸部31與卡合凹部32卡合時，會對卡合凸部31賦予反作用力之彈簧30(例如，捲繞彈簧)。 亦即，使卡合凸部31與卡合凹部32卡合時，藉由在彼此形成面接觸的第1卡合面33、37，賦予設置於擺動部20的後側之捲繞彈簧29的反作用力，在相對於該第1卡合面33、37呈垂直方向(將按摩構件14a朝外側打開的方向)上施加力，卡合片35被按壓至支撐部21而固定。In addition, the rotating shaft 28 around the engaging piece 35 is provided with a spring 30 (for example, a winding spring) that gives a reaction force to the engaging convex portion 31 when the engaging convex portion 31 is engaged with the engaging concave portion 32 ). That is, when the engaging convex portion 31 and the engaging concave portion 32 are engaged, the first engaging surfaces 33 and 37 that are in surface contact with each other provide the winding spring 29 provided on the rear side of the swinging portion 20. The reaction force exerts a force in a direction perpendicular to the first engagement surfaces 33 and 37 (the direction in which the massage member 14a is opened outward), and the engagement piece 35 is pressed to the support portion 21 and fixed.

於此同時，藉由在彼此面接觸的第2卡合面34、38，被賦予設置於擺動部20的前側之捲繞彈簧30的反作用力，在相對於該第2卡合面34、38呈垂直的方向(朝向支撐部21的方向)施加力，卡合片35會被按壓至支撐部21而固定。 亦即，由於在被卡合的卡合凸部31與卡合凹部32之間，施加有被施加在彼此面接觸之第1卡合面33、37的按壓力、與被施加在彼此面接觸之第2卡合面34、38的按壓力之兩個力，所以卡合片35會被按壓至支撐部21而確實地固定。At the same time, by the second engagement surfaces 34, 38 that are in surface contact with each other, the reaction force of the coil spring 30 provided on the front side of the swing portion 20 is applied to the second engagement surfaces 34, 38. When a force is applied in a vertical direction (direction toward the support portion 21), the engaging piece 35 is pressed to the support portion 21 and fixed. That is, because the pressing force applied to the first engaging surfaces 33, 37 that are in surface contact with each other is applied between the engaging convex portion 31 and the engaging concave portion 32 that are engaged Because of the two forces of the pressing force of the second engagement surfaces 34 and 38, the engagement piece 35 is pressed to the support portion 21 and fixed securely.

由以上，在本實施形態中，寬度調整手段15a係藉由使卡合片35的卡合凹部32卡合於設置在支撐部21的任一卡合凸部31以固定擺動部20，而構成為可將一對的按摩構件14之左右的間隔三階段地進行調整。 亦即，寬度調整手段15係作成可將左右一對的按摩構件14的間隔階段性地調整(本實施形態中，三階段地調整)之棘輪機構。From the above, in the present embodiment, the width adjusting means 15a is configured by engaging the engaging concave portion 32 of the engaging piece 35 with any of the engaging convex portions 31 provided on the supporting portion 21 to fix the swing portion 20. In order to be able to adjust the left and right intervals of the pair of massage members 14 in three stages. That is, the width adjustment means 15 is a ratchet mechanism that can adjust the interval between the pair of left and right massage members 14 in stages (in the present embodiment, adjustment in three stages).

以此方式，本發明的肩部按摩機構13係作成可以寬度調整手段15使左右一對的按摩構件14往斜下方移動，藉此可調整一對的按摩構件14之左右間隔，並可對應於使用者的各種體型。 ［作動態樣］ 其次，針對本發明的肩部按摩機構13的作動態樣，一邊參照圖式一邊說明。In this way, the shoulder massage mechanism 13 of the present invention is configured to allow the width adjustment means 15 to move the pair of left and right massage members 14 obliquely downward, thereby adjusting the left and right spacing of the pair of massage members 14, and can correspond to Various body types of users. [Make a dynamic sample] Next, the dynamics of the shoulder massage mechanism 13 of the present invention will be described with reference to the drawings.

如圖3～圖7等所示，作成從左右一對的按摩構件14的間隔最廣的狀態(開度最大的狀態)，將左右的間隔變窄。 左右一對的按摩構件14係固定於最外側(斜上方)。例如，右側的按摩構件14a係固定於最右外側(右斜上方)。 關於右側的寬度調整手段15a，卡合片35的卡合凹部32係與設置在支撐部21之最右外側的卡合凸部31卡合(參照圖7的上圖)。亦即，擺動部20相對於支撐部21成為開度最大(朝右斜上方上升)的狀態。此外，關於左側的按摩構件14b，係成為與右側的按摩構件14a呈鏡像的狀態。As shown in FIGS. 3 to 7 and the like, the left and right pair of massage members 14 have the widest interval (the state with the largest opening), and the left and right intervals are narrowed. The pair of left and right massage members 14 are fixed to the outermost side (obliquely upward). For example, the massage member 14a on the right side is fixed to the outermost right side (obliquely upper right). Regarding the width adjusting means 15a on the right side, the engagement recess 32 of the engagement piece 35 engages with the engagement protrusion 31 provided on the rightmost outer side of the support portion 21 (refer to the upper view of FIG. 7). In other words, the swing portion 20 has the largest opening degree with respect to the support portion 21 (increases diagonally upward to the right). In addition, the massage member 14b on the left side is in a mirror image state with the massage member 14a on the right side.

在此，使左右一對的按摩構件14朝最內側(斜下方)移動。亦即，將左右一對的按摩構件14的間隔縮小化。 例如，當使右側的按摩構件14a朝最左內側(左斜下方)移動時，在右側的寬度調整手段15a中，藉由卡合片35朝前方旋轉，卡合凹部32與卡合凸部31的卡合會被解除。Here, the pair of left and right massage members 14 are moved toward the innermost side (obliquely downward). That is, the interval between the pair of left and right massage members 14 is reduced. For example, when the massaging member 14a on the right is moved to the leftmost inner side (obliquely downward to the left), in the width adjusting means 15a on the right, the engaging piece 35 is rotated forward to engage the concave portion 32 and the convex portion 31. The card will be cancelled.

於是，右側的寬度調整手段15a係一邊使右側的按摩構件14a朝左方移動，一邊朝左斜下方擺動。且，藉由卡合片35朝後方旋轉，卡合凹部32係與設置在支撐部21之最左內側(左斜下方)的卡合凸部31卡合(參照圖7的下圖)。 在此卡合的卡合凸部31與卡合凹部32之間，藉由施加在彼此面接觸之第1卡合面33、37的按壓力、與施加在彼此面接觸之第2卡合面34、38的按壓力，卡合片35會被按壓至支撐部21，而確實地固定擺動部20。右側的按摩構件14a係構成為例如接近身材短小之使用者的右側肩部。Then, the width adjustment means 15a on the right side moves the massage member 14a on the right side to the left while swinging diagonally downward to the left. In addition, as the engaging piece 35 rotates rearward, the engaging concave portion 32 engages with the engaging convex portion 31 provided on the leftmost inner side (obliquely lower left) of the support portion 21 (refer to the lower diagram of FIG. 7). Between the engaging convex portion 31 and the engaging concave portion 32 that are engaged with each other, the pressing force applied to the first engaging surfaces 33 and 37 that are in surface contact with each other, and the second engaging surface that is applied to each other in surface contact With the pressing force of 34 and 38, the engaging piece 35 is pressed to the support part 21, and the swing part 20 is surely fixed. The massage member 14a on the right side is configured to be close to the right shoulder of a user with a short stature, for example.

另一方面，左側的寬度調整手段15b係一邊使左側的按摩構件14b朝右方移動，一邊使之朝右斜下方擺動。此左側的寬度調整手段15b之動作係與右側的寬度調整手段15a呈鏡像。左側的按摩構件14b係例如接近身材短小之使用者的左側肩部。 此外，在從左右一對的按摩構件14的間隔最窄的狀態(開度最小的狀態)擴展左右的間隔時，以利用上述的程序相反的程序來進行即可。On the other hand, the width adjusting means 15b on the left side moves the massage member 14b on the left side to the right while swinging it diagonally downward to the right. The operation of the width adjusting means 15b on the left is mirror images of the width adjusting means 15a on the right. The left massage member 14b is, for example, close to the left shoulder of a user with a short stature. In addition, when the left and right intervals are expanded from the state in which the interval between the pair of left and right massage members 14 is the narrowest (the state in which the opening is the smallest), it is only necessary to perform the procedure opposite to the above procedure.

亦即，在擴展左右一對的按摩構件14的間隔(返回通常狀態)時，例如，右側的寬度調整手段15a係一邊使右側的按摩構件14a朝右方移動，一邊朝右斜上方擺動。使卡合片35的卡合凹部32與設置在支撐部21之最右外側的卡合凸部31卡合。右側的按摩構件14a係成為例如接近身材高大之使用者的右側肩部。又，左側的寬度調整手段15b係一邊使左側的按摩構件14b朝左方移動，一邊朝左斜上方擺動而固定。左側的按摩構件14b係成為例如接近身材高大之使用者的左側肩部。That is, when the interval between the pair of left and right massage members 14 is expanded (returns to the normal state), for example, the width adjustment means 15a on the right side moves the right massage member 14a to the right and swings diagonally upward and right. The engaging concave portion 32 of the engaging piece 35 is engaged with the engaging convex portion 31 provided on the rightmost outer side of the support portion 21. The massage member 14a on the right side becomes, for example, close to the right shoulder of a tall user. In addition, the width adjusting means 15b on the left side moves the massage member 14b on the left side to the left while swinging it diagonally upward to the left and is fixed. The massage member 14b on the left side becomes, for example, close to the left shoulder of a tall user.

以上，根據本發明的肩部按摩機構13，透過寬度調整手段15使左右一對的按摩構件14往斜下方移動以調整左右的間隔，藉此例如可配合使用者的體型(肩寬等)。亦即，即便是肩寬窄之身材短小的使用者，也可使用肩部按摩機構13。 此外，本次所揭示的實施形態，全部的點係為例示，不應被認為用於限制。As described above, according to the shoulder massage mechanism 13 of the present invention, the pair of left and right massage members 14 are moved obliquely downward through the width adjustment means 15 to adjust the left and right intervals, so as to match the user's body shape (shoulder width, etc.). In other words, even users of short stature with narrow shoulders can use the shoulder massage mechanism 13. In addition, all the points in the embodiment disclosed this time are examples and should not be considered as limiting.

尤其，此次所揭示的實施形態中，未明示的事項，例如作動條件、操作條件、構成物的尺寸；重量等，並不脫離所屬技術領域中具有通常知識者通常實施的範圍，只要是一般的所屬技術領域中具有通常知識者，採用有可容易地假定之事項。 此外，關於本發明的肩部按摩機構13的構成，只要是具有以左右一對的按摩構件14挾持使用者的施療部之構成的按摩機構，則可適用。可列舉例如具有挾持使用者的腿部、腰部(臀部)等下肢之構成的座部按摩機構10等。於此情況，藉由以寬度調整手段15調整左右一對的按摩構件14的間隔，可配合腿部的粗度。In particular, in the embodiment disclosed this time, the unspecified matters, such as operating conditions, operating conditions, size of the structure, weight, etc., do not deviate from the scope that a person with ordinary knowledge in the technical field usually implements, as long as it is general Those who have general knowledge in the technical field of their respective fields use items that can be easily assumed. In addition, as for the structure of the shoulder massage mechanism 13 of the present invention, it can be applied as long as it has a structure in which a pair of left and right massage members 14 sandwich the user's treatment part. For example, the seat massaging mechanism 10 etc. which have the structure which pinches a user's legs, waist (buttocks), etc. are mentioned. In this case, by adjusting the interval between the pair of left and right massage members 14 by the width adjustment means 15, the thickness of the legs can be adjusted.

又，關於背部按摩機構7、座部按摩機構10、下肢按摩機構11、臂部按摩機構12等的裝置構成，可採用各種機構，無特別限定。In addition, with regard to the device configuration of the back massage mechanism 7, the seat massage mechanism 10, the lower extremity massage mechanism 11, the arm massage mechanism 12, etc., various mechanisms can be adopted and are not particularly limited.
