The trolley | bogie fixed part 5 comprises the 3rd delivery member which delivers the mounting part 10 between the bathtub 2 side and the conveyance vehicle 3 side by comprising the level | step-difference part 5d as a rail part.

台車固定部５には、台車部９が台車固定部５により浴槽２に連結固定されているとき以外は、移動機構６上での搭載部１０の左右方向の移動を阻止する第一の移動阻止機構部１７が設けられている。 A first movement blocking mechanism for blocking movement of the mounting portion 10 in the lateral direction on the moving mechanism 6 except when the carriage portion 9 is connected and fixed to the bathtub 2 by the carriage fixing portion 5 in the carriage fixing portion 5 A mechanism unit 17 is provided.

図６Ａ、図６Ｂに示すように、第一の移動阻止機構部１７は、台車固定部５から上端部が突出退避可能なロック部材１７ａと、このロック部材１７ａの下端側と一体で他端側が軸１７ｄで軸支されているロック解除部材１７ｂ(ロック部材１７ａとは一体物)と、これらを時計回り方向(ロック方向)に付勢するバネ部材１７ｃとを備え、ロック解除部材１７ｂは、台車固定部５の溝部分５ｃに形成された貫通穴５ｅから突出または退避可能であり、ロック部材１７ａは台車固定部５の本体部分５ｂに形成された貫通穴５ｆから突出または退避可能である。 As shown in FIGS. 6A and 6B, the first movement preventing mechanism unit 17 is integrally formed with the lower end side of the lock member 17a whose upper end can project and retract from the carriage fixing unit 5 and the other end side The lock release member 17b (an integral body with the lock member 17a) supported pivotally by the shaft 17d and a spring member 17c biasing the members in the clockwise direction (lock direction) are provided. The lock release member 17b is a bogie The lock member 17 a can be protruded or retracted from the through hole 5 e formed in the groove portion 5 c of the fixed portion 5, and the lock member 17 a can be protruded or retracted from the through hole 5 f formed in the main body portion 5 b of the carriage fixed portion 5.

ロック部材１７ａは、係合部材１５の係合用端部１５ｂが台車固定部５の溝部分５ｃに入り込んでいない時は、バネ部材１７ｃの付勢で台車固定部５から突出し、ロック解除部材１７ｂは、溝部分５ｃから突出している。この突出状態で、第一の移動阻止機構部１７は、搬送車３側と浴槽２側との間での搭載部１０の移動を阻止する。 When the engaging end 15b of the engaging member 15 does not enter the groove 5c of the carriage fixing portion 5, the locking member 17a projects from the carriage fixing portion 5 by the biasing of the spring member 17c, and the unlocking member 17b , And protrudes from the groove portion 5c. In this projecting state, the first movement preventing mechanism 17 prevents movement of the mounting unit 10 between the side of the carrier 3 and the side of the bathtub 2.

係合部材１５の係合用端部１５ｂが台車固定部５の溝部分５ｃに入り込むと、ロック解除部材１７ｂがバネ部材１７ｃの付勢に抗して押されて反時計回り方向に回動し溝部分５ｃ内に退避し、これと共にロック部材１７ａは台車固定部５内に退避する。その結果、第一の移動阻止機構部１７は、搬送車３側と浴槽２側との間での搭載部１０の移動を許容する。 When the engaging end portion 15b of the engaging member 15 enters the groove portion 5c of the carriage fixing portion 5, the unlocking member 17b is pushed against the biasing force of the spring member 17c and rotates in the counterclockwise direction. Withdraws into the portion 5 c and with this, the lock member 17 a withdraws into the carriage fixing portion 5. As a result, the first movement preventing mechanism unit 17 permits movement of the mounting unit 10 between the side of the carrier 3 and the side of the bathtub 2.

搬送車３の台車部９には、第二の移動阻止機構部１８が設けられている。第二の移動阻止機構部１８は、当該台車部９が台車固定部５により浴槽２に連結固定されている時以外は、台車部９上での搭載部１０の移動を阻止(ロック状態)する。 The carriage portion 9 of the carrier 3 is provided with a second movement preventing mechanism unit 18. The second movement blocking mechanism 18 blocks movement of the mounting unit 10 on the carriage unit 9 (locked state) except when the carriage unit 9 is connected and fixed to the bathtub 2 by the carriage fixing unit 5. .

第二の移動阻止機構部１８は、係合部材１５に設けられた軸１８ｃの周りに一体回転可能なロック解除部材１８ａと、これと一体のロック部材１８ｂとを具備し、これらはバネ部材１８ｄ（付勢部材）で反時計回り方向に付勢されている。ロック部材１８ｂは、バネ部材１８ｄの付勢で搭載部１０下面上に突出し該下面側の係合部１０ｄ（第一の係合部分）に係合すると、搭載部１０はロック部材１８ｂにより台車部９上で移動することを阻止(ロック)され、台車部９上から脱落することを防止される。 The second movement preventing mechanism 18 comprises an unlocking member 18a which can be integrally rotated about a shaft 18c provided on the engaging member 15, and a locking member 18b which is integral therewith, and these are a spring member 18d. It is biased in the counterclockwise direction by the (biasing member). When the locking member 18b is projected on the lower surface of the mounting portion 10 by the urging of the spring member 18d and engaged with the engaging portion 10d (first engaging portion) on the lower surface side, the mounting portion 10 is locked by the locking member 18b. The movement on the carriage 9 is blocked (locked) and the carriage 9 is prevented from falling off.

また、第二の移動阻止機構部１８は、図７に示すように、入浴者が片手で同時にこれら第二の移動阻止機構部１８を操作できない間隔で係合部材１５の幅方向に沿って複数（図７では２つ）設けられている。これにより、次の効果が得られる。すなわち、台車部９が斜め方向から誤って浴槽２に連結された場合、両第二の移動阻止機構部１８、１８は、時間的に前後して台車固定部５への係合を開始する。そのため、斜め連結を終えた状況では、先に台車固定部５への連結を開始した第二の移動阻止機構部１８は上述したロック解除を行ってしまう可能性があるものの、後から台車固定部５への連結を開始した第二の移動阻止機構部１８は、上述したロック解除が行われない。これにより、台車部９の斜め連結時における第二の移動阻止機構部１８のロック誤解除が防止される。 In addition, as shown in FIG. 7, the second movement preventing mechanism 18 has a plurality of members along the width direction of the engaging member 15 at intervals at which the bather can not operate the second movement preventing mechanism 18 simultaneously with one hand. (2 in FIG. 7) are provided. By this, the following effects can be obtained. That is, when the carriage portion 9 is erroneously connected to the bathtub 2 from an oblique direction, both the second movement preventing mechanism portions 18 start to engage with the carriage fixing portion 5 temporally before and after. Therefore, in the situation where the diagonal connection has been completed, the second movement preventing mechanism unit 18 which has first started the connection to the carriage fixing unit 5 may perform the above-mentioned unlocking, but the trolley fixing unit is later The second movement preventing mechanism 18 that has started to be connected to 5 is not unlocked as described above. Thereby, the erroneous release of the lock of the second movement prevention mechanism unit 18 at the time of the diagonal connection of the carriage unit 9 is prevented.

また、第二の移動阻止機構部１８は上記のように設けられているので、浴槽２に連結されていない場合に、入浴者の誤使用により、同時に全ての第二の移動阻止機構部１８、１８をロック解除されることが阻止され、台車部９上から搭載部１０が脱落することが防止される。 In addition, since the second movement preventing mechanism 18 is provided as described above, all the second movement preventing mechanism 18 are simultaneously used by a bather's misuse when the second movement preventing mechanism 18 is not connected to the bathtub 2. The lock release 18 is prevented from being released, and the mounting portion 10 is prevented from falling off the carriage portion 9.

台車部９が浴槽２方向に押されると、台車部９側面から突出する係合部材１５の係合用端部１５ｂはバネ部材の付勢に抗して台車固定部５の傾斜部分５ａ上を昇っていって、台車固定部５の溝部分５ｃにバネ部材の付勢で入り込む。係合用端部１５ｂが溝部分５ｃに入ると台車部９は台車固定部５に連結固定され、第一の移動阻止機構部１７は搬送車３側から浴槽２側への搭載部１０の移動を許容すると共に、第二の移動阻止機構部１８のロック部材１８ｂが台車部９内に退避するので、第一の移動阻止機構部１７と第二の移動阻止機構部１８が共にロック解除状態となって搭載部１０は台車部９上から浴槽２側への移動が許容される。 When the carriage portion 9 is pushed in the direction of the bathtub 2, the engagement end 15b of the engagement member 15 protruding from the side surface of the carriage portion 9 rises on the inclined portion 5a of the carriage fixing portion 5 against the bias of the spring member. Then, it enters into the groove portion 5c of the carriage fixing portion 5 by the urging of the spring member. When the engagement end portion 15b enters the groove portion 5c, the carriage portion 9 is connected and fixed to the carriage fixing portion 5, and the first movement preventing mechanism 17 moves the mounting portion 10 from the carrier 3 side to the bathtub 2 side. Since the lock member 18b of the second movement prevention mechanism 18 retracts into the carriage 9 while being allowed, both the first movement prevention mechanism 17 and the second movement prevention mechanism 18 are unlocked. The mounting unit 10 is allowed to move from the top of the carriage 9 to the bathtub 2 side.

図８に示すように、台車部９は、搬送車３側と浴槽２側との間で搭載部１０を受け渡すための第二の受け渡し部材として、左右方向平行に対向する一対のレール部材９ａを備える。この一対のレール部材９ａの前後方向の対向間隔は、前記した第一、第三の受け渡し部材である載置部７の一対のレール部材７ａ、台車固定部５の一対の段差部分(レール部)５ｄそれぞれの対向間隔に対応している。 As shown in FIG. 8, the carriage portion 9 is a pair of rail members 9 a facing in parallel in the left-right direction as a second delivery member for delivering the mounting portion 10 between the carrier 3 side and the bathtub 2 side. Equipped with The distance between the pair of rail members 9a in the front-rear direction is the pair of rail members 7a of the mounting portion 7 as the first and third transfer members and the pair of step portions (rail portions) of the carriage fixing portion 5 It corresponds to each opposing interval of 5 d.

第一ないし第三の受け渡し部材により、搬送車３側と浴槽２側との間で搭載部１０の受け渡しが可能で搭載部１０は台車部９と移動機構６との間を安全に往復移動することができる。 The loading portion 10 can be delivered between the carriage 3 side and the bathtub 2 side by the first to third delivery members, and the loading portion 10 safely reciprocates between the carriage portion 9 and the moving mechanism 6 be able to.

台車固定部５と第一の移動阻止機構部１７は、平面視で左右方向において対称に形成されており、これにより、図９Ａ、図９Ｂを参照して後述するように浴槽２の左右側壁のいずれにおいても、台車固定部５を浴槽２に取着できる。 The carriage fixing portion 5 and the first movement preventing mechanism portion 17 are formed symmetrically in the left and right direction in plan view, and thereby, on the left and right side walls of the bathtub 2 as described later with reference to FIGS. 9A and 9B. In any case, the carriage fixing portion 5 can be attached to the bathtub 2.

図５に示すように、台車固定部５の溝部分５ｃは、前後方向に直線状の第一の溝部分５ｃ１と、第一の溝部分５ｃ１の前後方向両側のＲ状の第二の溝部分５ｃ２とからなる。また、台車部９の係合部材１５の係合用端部１５ｂは、第一の溝部分５ｃ１に対応する直線状の第一の係合用端部１５ｂ１と、第二の溝部分５ｃ２に対応してＲ状で第一の係合用端部１５ｂ１両側の第二の係合用端部１５ｂ２とからなる。 As shown in FIG. 5, the groove portion 5c of the carriage fixing portion 5 has a first groove portion 5c1 which is linear in the front-rear direction and an R-shaped second groove portion on both sides in the front-rear direction of the first groove portion 5c1. It consists of 5c2. Further, the engagement end 15b of the engagement member 15 of the carriage 9 corresponds to the linear first engagement end 15b1 corresponding to the first groove portion 5c1 and the second groove portion 5c2. It has an R-shaped first engaging end 15b1 and second engaging ends 15b2 on both sides.

第一の溝部分５ｃ１と第一の係合用端部１５ｂ１は共に直線状であるので、第一の溝部分５ｃ１に第一の係合用端部１５ｂ１が係合すると、搬送車３は、浴槽２の外側面に平行に位置決めされる。 Since the first groove portion 5c1 and the first engagement end 15b1 are both linear, when the first engagement end 15b1 is engaged with the first groove portion 5c1, the transport vehicle 3 is moved to the bathtub 2 Parallel to the outer surface of the

つまり、台車固定部５と台車部９の係合部材１５は、入浴のため浴槽２へ搭載部１０を移動させる際に、浴槽２に対して搬送車３を特定の位置に位置決めする位置決め手段を構成する。 That is, when the carriage fixing portion 5 and the engaging members 15 of the carriage portion 9 move the mounting portion 10 to the bathtub 2 for bathing, positioning means for positioning the transport vehicle 3 at a specific position with respect to the bathtub 2 is used. Configure.

この位置決め手段により、浴槽２に対して搬送車３は前記特定の位置に位置決めされる。この特定の位置は、搬送車３の台車部９を浴槽２に連結固定する位置である。 The carrier 3 is positioned at the specific position with respect to the bathtub 2 by this positioning means. The specific position is a position where the carriage portion 9 of the carrier 3 is connected and fixed to the bathtub 2.

上記位置決め手段は、搬送車３の台車部９と浴槽２との連結位置を位置決めしてこれらを連結固定することができ、前記特定の位置で浴槽２に台車部９を固定可能とする連結機構を構成する。 The positioning means can position the connecting position of the carriage 9 of the carrier 3 and the bath 2 and connect and fix them, and a connecting mechanism which can fix the carriage 9 to the bath 2 at the specific position. Configure

ここで、図９Ａに示すように、台車部９は、搭載部１０の中央断面Ｃ１（本実施例では平面視で搭載部１０に搭載した入浴者の正中面に一致）と浴室床面とに垂直な面を基準面９ｃ１として、または、前記特定の位置に位置決めされた状態で、浴槽２の側壁の一端に近接する台車部９の一端を通る垂線を基準線９ｃ２として対称に形成されている。 Here, as shown in FIG. 9A, the carriage portion 9 is provided on the central cross section C1 of the mounting portion 10 (in the present embodiment, it corresponds to the median plane of the bather mounted on the mounting portion 10 in plan view) and the bathroom floor. A vertical line is formed symmetrically as a reference plane 9c1 or a vertical line passing through one end of the carriage 9 close to one end of the side wall of the bathtub 2 as a reference line 9c2 while being positioned at the specific position. .

そのため、台車固定部５が浴槽２の左右どちらの側壁の一端に設けられても、前記位置決め手段を組み替える必要なく、操作ペダル１４を組み替えるのみの軽微な作業で、浴槽２の台車固定部５に搬送車３の台車部９を位置決めして連結固定することができる。 Therefore, it is not necessary to rearrange the positioning means even if the truck fixing portion 5 is provided at one end of either the left or right side wall of the bathtub 2, and the truck fixing portion 5 of the bathtub 2 is only a minor operation. The carriage portion 9 of the transport vehicle 3 can be positioned and connected and fixed.

その結果、前記位置決めのための各種の煩わしい位置調整作業が不要となるうえ、右仕様、左仕様といった機種の入浴装置を個々に製造販売する手間がなくなり、安価な入浴装置を提供することができる。また、１つの機種の入浴装置で多様な浴室内レイアウトに対応することができる。 As a result, various troublesome position adjustment operations for the positioning become unnecessary, and it is not necessary to individually manufacture and sell bathing devices of the right specification and left specification, and an inexpensive bathing device can be provided. . In addition, it is possible to cope with various in-bath layouts with one type of bathing apparatus.

この場合、前記基準線９ｃ２は、搭載部１０が浴槽２内に前記第一ないし第三の受け渡し部材により、直線軌道に沿って移動される方向と平行である。また、搭載部１０は、その中心線Ｃ２（平面視で搭載部１０に搭載した入浴者の正中線に一致）が基準線９ｃ２に対して垂直となるように台車部９に載置される。これにより、搭載部１０を回転させて浴槽２内に移動させる回転式の構成と比較して、台車部９を浴槽２の左右どちらからでも台車部９上と浴槽２内で同一の直線軌道に沿って最短距離で搭載部１０を移動でき、移動介助負担が軽減できる。 In this case, the reference line 9c2 is parallel to the direction in which the mounting portion 10 is moved along the linear track by the first to third delivery members in the bathtub 2. The mounting unit 10 is mounted on the carriage unit 9 so that the center line C2 (which coincides with the midline of the bather mounted on the mounting unit 10 in plan view) is perpendicular to the reference line 9c2. As a result, as compared with the rotary type configuration in which the loading unit 10 is rotated and moved into the bathtub 2, the truck unit 9 is on the same straight track on the carriage unit 9 and inside the bathtub 2 from either left or right of the bathtub 2. The loading unit 10 can be moved along the shortest distance, and the movement assistance burden can be reduced.

また、浴槽２内に入浴者を移動させる方向のまま、浴槽２の左右どちらからでも搭載部１０を方向転換することなく、浴槽２内に移動でき、搭載部１０の移動時の入浴者の恐怖感を軽減できる。 In addition, with the direction to move the bather into the bathtub 2, it is possible to move the inside of the mounting unit 10 from the left or right of the bathtub 2 without turning the mounting unit 10, and the fear of the bather when moving the mounting unit 10. You can reduce the feeling.

また、台車部９を浴槽２に固定しない機種の入浴装置と比較して、台車部９が浴槽２に確実に位置決めされて前記連結機構で連結固定されるので、搭載部１０を往復移動する途中で台車部９が不用意に動いて搭載部１０が台車部９や浴槽２から転落する事故を防止することができる。 Further, as compared with the type of bathing apparatus in which the carriage 9 is not fixed to the bathtub 2, the carriage 9 is reliably positioned on the bathtub 2 and connected and fixed by the connection mechanism. Thus, it is possible to prevent an accident in which the mounting portion 10 falls from the trolley portion 9 or the bathtub 2 due to the trolley portion 9 moving carelessly.

台車部９は、台車部９の前後方向において平行に対向する一対の第一のフレーム部材１１ａと、台車部９の左右方向において平行に対向する一対の第二のフレーム部材１１ｂと、第一のフレーム部材１１ａの前後方向端部それぞれの車輪１２と、第二のフレーム部材１１ｂ上のレール部材９ａ(第二の受け渡し部材)とを備えている。 The carriage portion 9 includes a pair of first frame members 11a opposed in parallel in the front-rear direction of the carriage portion 9, a pair of second frame members 11b opposed in parallel in the left-right direction of the carriage portion 9, and a first A wheel 12 at each end of the frame member 11a in the front-rear direction and a rail member 9a (second delivery member) on the second frame member 11b are provided.

ここで台車部９の前後方向は、台車部９上の搭載部１０に搭載されている入浴者の正面側が台車部９の前方向であり、台車部９上の搭載部１０に搭載されている入浴者の背面側が台車部９の後方向である。台車部９の左右方向は、台車部９の前後方向に直交する方向である。また、台車部９の前後方向および左右方向は、浴槽２の前後方向および左右方向とは独立したものであるが、図９Ａでは台車部９の前後左右方向と浴槽２の前後左右方向とは一致している。 Here, the front side of the bather who is mounted on the mounting unit 10 on the carriage unit 9 is the front direction of the carriage unit 9 in the front-rear direction of the carriage unit 9 and is mounted on the mounting unit 10 on the carriage unit 9 The back side of the bather is the back direction of the carriage 9. The left-right direction of the carriage portion 9 is a direction orthogonal to the front-rear direction of the carriage portion 9. Although the longitudinal direction and the lateral direction of the carriage portion 9 are independent of the longitudinal direction and the lateral direction of the bathtub 2, in FIG. 9A, the longitudinal direction and the lateral direction of the carriage portion 9 and the longitudinal direction and the lateral direction of the bathtub 2 are one. I do.

そして、一対の第一のフレーム部材１１ａの左右方向の対向間には、入浴介助者が入浴者の入浴介助作業を行うために容易に踏み込むことができる第一の空間Ｓ１が前後方向両側に形成され、また、一対の第二のフレーム部材１１ｂの前後方向の対向間には、入浴介助者が搭載部１０を浴槽２の方向に容易に移動させることができるように踏み込むことができる第二の空間Ｓ２が形成されている。 And between the opposing of the left-right direction of a pair of 1st frame members 11a, the 1st space S1 which a bathing assistant can easily step in in order to perform bathing assistance work of a bather is formed in the front-back direction both sides Also, between the facing in the front-rear direction of the pair of second frame members 11b, the bathing assistant can step in so that the mounting portion 10 can be easily moved in the direction of the bathtub 2 Space S2 is formed.

一対の第一の空間Ｓ１のうち、前方向の空間Ｓ１´は搭載部１０の下腿支持部１０ｃの収納に利用することができる。これにより、前方向の空間Ｓ１´は踏み込みスペースとして空くので、入浴介助者は前方向の空間Ｓ１´に踏み込んで入浴者の移乗介助作業ができ、その作業負担が軽減され、また、図１５に示すように、入浴者の起立動作の際の足元スペースとしても活用できる。 Of the pair of first spaces S1, the forward space S1 ′ can be used to store the lower thigh support 10c of the mounting portion 10. As a result, since the forward space S1 'is freed as a stepping space, the bathing assistant can step into the forward space S1' to perform the transfer work of the bather, and the work load is reduced, and FIG. As shown, it can also be used as a foot space for the bather's standing movement.

第二の空間Ｓ２は、台車部９の左右方向の中央を超えて浴槽２側に至る奥行きのある広い空間となっている。そのため、入浴介助者が搬送車３を浴槽２に固定操作し、次いで搭載部１０を台車部９の第二の受け渡し部材上から浴槽２側に移動させるとき、入浴介助者は、台車部９の第二の空間Ｓ２に足を踏み込んで搭載部１０の移動作業ができる。これにより入浴介助者は、入浴者を搭載部１０と共に浴槽２側に移乗させる介助作業の負担が軽減され、当該作業で腰などを痛めるリスクが低減される。 The second space S2 is a wide space having a depth extending beyond the center of the carriage 9 in the left-right direction to the bathtub 2 side. Therefore, when the bathing assistant fixes the transport vehicle 3 to the bath 2 and then moves the mounting portion 10 from the second delivery member of the carriage 9 to the bathtub 2 side, the bathing assistant takes the position of the carriage 9 Stepping in the second space S2 allows the loading unit 10 to be moved. As a result, the burden of assistance work for transferring a bather to the bathtub 2 side together with the loading unit 10 is reduced, and the risk of hurting the waist or the like in the work is reduced.

図９Ａでは台車固定部５は浴槽２の一方の側壁に固定されているが、台車部９は前後左右に対称的になっているので、図９Ｂに示すように、台車固定部５を浴槽２の他方の側壁に固定し、台車部９を浴槽２の他方の側壁に固定することができる。このように台車固定部５は浴槽２の左右側壁のどちら側に取着しても台車部９を浴槽２に連結固定できるので、浴槽２の様々なレイアウトに対応できる。 The carriage fixing portion 5 is fixed to one side wall of the bathtub 2 in FIG. 9A, but since the carriage portion 9 is symmetrical in the front, rear, left and right, as shown in FIG. The carriage portion 9 can be fixed to the other side wall of the bath 2 by fixing it to the other side wall of the tub 2. As described above, even if the carriage fixing portion 5 is attached to either side of the left and right side walls of the bathtub 2, the carriage portion 9 can be connected and fixed to the bathtub 2, so that various layouts of the bathtub 2 can be accommodated.

図１０Ａないし図１０Ｃを参照して、搭載部１０はその移動方向上の異なる位置に、台車固定部５の第一の移動阻止機構部１７のロック部材１７ａまたは第二の移動阻止機構部１８のロック部材１８ｂと係合可能な三つの第一〜第三の係合部分を有する。ここで、第一の係合部分は、搭載部１０の下面の係合部１０ｄであり、第二の係合部分は、搭載部１０下部の係合用穴部１０ｅであり、第三の係合部分は、搭載部１０下部の係合用穴部１０ｆである。なお、第一〜第三の係合部分の形状は上記に限定されず、凹部や穴部、その他であってもよく、その組合せは任意である。 Referring to FIGS. 10A to 10C, the mounting unit 10 is located at a different position in the moving direction of the lock member 17a of the first movement preventing mechanism 17 or the second movement preventing mechanism 18 of the carriage fixing unit 5. It has three first to third engagement portions engageable with the lock member 18b. Here, the first engagement portion is the engagement portion 10d of the lower surface of the mounting portion 10, and the second engagement portion is the engagement hole portion 10e at the lower portion of the mounting portion 10, and the third engagement portion The portion is an engagement hole 10 f in the lower portion of the mounting portion 10. In addition, the shape of a 1st-3rd engaging part is not limited above, A recessed part, a hole part, etc. may be sufficient, and the combination is arbitrary.

搭載部１０はこれら係合部分１０ｄ，１０ｅ，１０ｆを有することにより、搭載部１０が台車部９又は載置部７から誤って転落することがないように、その移動方向上の異なる第一〜第四の所定位置でロックすることができる。ここで、第一の所定位置は、台車部９上で搭載部１０がロック部材１８ｂと係合部１０ｄでロックされる位置であり、第二の所定位置は、台車部９上で搭載部１０がロック部材１８ｂと係合用穴部１０ｅでロックされる位置である。また、第三の所定位置は、載置部７上で搭載部１０がロック部材１７ａと係合部１０ｄでロックされる位置であり、第四の所定位置は、載置部７上で搭載部１０がロック部材１７ａと係合用穴部１０ｆでロックされる位置である。 The mounting portion 10 has the engaging portions 10d, 10e and 10f, so that the mounting portion 10 does not fall from the carriage portion 9 or the mounting portion 7 by mistake, the first to It can be locked in the fourth predetermined position. Here, the first predetermined position is a position where the mounting portion 10 is locked by the locking member 18 b and the engaging portion 10 d on the carriage portion 9, and the second predetermined position is the mounting portion 10 on the carriage portion 9. Is a position locked by the locking member 18b and the engagement hole 10e. Further, the third predetermined position is a position where the mounting portion 10 is locked on the mounting portion 7 by the locking member 17 a and the engaging portion 10 d, and the fourth predetermined position is the mounting portion on the mounting portion 7 10 is a position where it is locked by the locking member 17a and the engagement hole 10f.

搭載部１０が台車部９上を移動する際には、第二の移動阻止機構部１８のロック部材１８ｂが係合部１０ｄと係合すると、搭載部１０が第一の所定位置から移動することを阻止(第一のロック状態)される。また、第二の移動阻止機構部１８のロック部材１８ｂが係合用穴部１０ｅと係合すると、搭載部１０が第二の所定位置から移動することを阻止(第二のロック状態)される。 When the mounting unit 10 moves on the carriage unit 9, when the lock member 18 b of the second movement prevention mechanism unit 18 engages with the engaging unit 10 d, the mounting unit 10 moves from the first predetermined position. To be blocked (first locked state). In addition, when the lock member 18b of the second movement prevention mechanism 18 engages with the engagement hole 10e, the movement of the mounting unit 10 from the second predetermined position is blocked (a second locked state).

このように第二の移動阻止機構部１８は、ロック部材１８ｂが台車部９から突出して搭載部１０の係合部１０ｄに係合して搭載部１０が台車部９から転落することを第一のロック状態で阻止する。しかしながら、誤操作により、ロック部材１８ｂが搭載部１０の係合部１０ｄに係合できず、そのため搭載部１０が、脱落方向に、第一の所定位置から第二の所定位置の距離分、移動しても、ロック部材１８ｂがバネ部材１８ｄの付勢力で係合用穴部１０ｅに入り込む。これにより、搭載部１０の移動を第二のロック状態になって阻止することができるので、搭載部１０の台車部９からの転落を防止することができる。 As described above, in the second movement preventing mechanism unit 18, the locking member 18b protrudes from the carriage unit 9 and engages with the engaging unit 10d of the mounting unit 10 to cause the mounting unit 10 to fall from the carriage unit 9 Block in the locked state. However, the locking member 18b can not engage with the engaging portion 10d of the mounting portion 10 due to an erroneous operation, so the mounting portion 10 moves in the dismounting direction by the distance of the second predetermined position from the first predetermined position. Even in this case, the lock member 18b enters the engagement hole 10e by the biasing force of the spring member 18d. As a result, the movement of the mounting unit 10 can be prevented in the second locked state, so that the falling of the mounting unit 10 from the carriage unit 9 can be prevented.

搭載部１０は、第二の所定位置から第一の所定位置へ容易に移動されることが可能である。この場合、ロック部材１８ｂの面取りされている上面１８ｅが、係合用穴部１０ｅの端面と接触してロック部材１８ｂが軸１８ｃを中心として時計回りに回転されて係合用穴部１０ｅから退避する。従って、ロック部材１８ｂと係合用穴部１０ｅとが互いに干渉しなくなるので、搭載部１０を第二の所定位置から第一の所定位置へ容易に戻すことができる。 The mounting unit 10 can be easily moved from the second predetermined position to the first predetermined position. In this case, the chamfered upper surface 18e of the lock member 18b contacts the end face of the engagement hole 10e, and the lock member 18b is rotated clockwise about the shaft 18c to retract from the engagement hole 10e. Therefore, since the lock member 18b and the engagement hole 10e do not interfere with each other, the mounting portion 10 can be easily returned from the second predetermined position to the first predetermined position.

また、搭載部７が第二の所定位置においては、搭載部７及びこれに搭載された入浴者の重心が偏ってしまって不安定な状態となっているので、上記のように搭載部７が第一の所定位置へ戻されることにより、搭載部７および入浴者の態勢を安定化して入浴者の安全を確保することができる。 Further, at the second predetermined position of the mounting portion 7, the center of gravity of the mounting portion 7 and the bather mounted thereon is biased to be in an unstable state. By returning to the first predetermined position, the mounting portion 7 and the bather's posture can be stabilized to secure the bather's safety.

搭載部１０が載置部７上を移動する際には、第一の移動阻止機構部１７のロック部材１７ａが係合部１０ｄと係合すると、搭載部１０が第三の所定位置から移動することを阻止(第三のロック状態)される。また、第一の移動阻止機構部１７のロック部材１７ａが係合用穴部１０ｆと係合すると、搭載部１０が第四の所定位置から移動することを阻止(第四のロック状態)される。 When the mounting unit 10 moves on the mounting unit 7, when the lock member 17 a of the first movement prevention mechanism unit 17 engages with the engaging unit 10 d, the mounting unit 10 moves from the third predetermined position. Being blocked (third locked state). In addition, when the lock member 17a of the first movement prevention mechanism 17 engages with the engagement hole 10f, the movement of the mounting unit 10 from the fourth predetermined position is blocked (fourth lock state).

このように第一の移動阻止機構部１７は、ロック部材１７ａが台車固定部５から突出して搭載部１０の係合部１０ｄに係合して搭載部１０が載置部７から転落することを第三のロック状態で阻止する。しかしながら、誤操作により、ロック部材１７ａが搭載部１０の係合部１０ｄに係合できず、そのため搭載部１０が、脱落方向に、第三の所定位置から第四の所定位置の距離分、移動しても、ロック部材１７ａがバネ部材１７ｃの付勢力で係合用穴部１０ｆに入り込む。これにより、搭載部１０の移動を第四のロック状態になって阻止することができるので、搭載部１０の載置部７からの転落を防止することができる。 As described above, in the first movement preventing mechanism unit 17, the locking member 17 a protrudes from the carriage fixing unit 5 and engages with the engaging unit 10 d of the mounting unit 10 so that the mounting unit 10 falls from the mounting unit 7. Block in the third lock state. However, the locking member 17a can not engage with the engaging portion 10d of the mounting portion 10 due to an erroneous operation, so the mounting portion 10 moves in the dismounting direction by the distance from the third predetermined position to the fourth predetermined position. Even in this case, the lock member 17a enters the engagement hole 10f by the biasing force of the spring member 17c. As a result, the movement of the mounting unit 10 can be prevented in the fourth locked state, so that the falling of the mounting unit 10 from the mounting unit 7 can be prevented.

搭載部１０は、第四の所定位置から第三の所定位置へ容易に移動されることが可能である。この場合、ロック部材１７ａは、軸１７ｄを中心としてバネ部材１７ｃにより反時計回りにも回転可能なので、ロック部材１７ａが係合用穴部１０ｆの端面と接触して、このロック部材１７ａが反時計回りに回転されて係合用穴部１０ｆから退避する。従って、ロック部材１７ａと係合用穴部１０ｆとが互いに干渉しなくなるので、搭載部１０が第四の所定位置から第三の所定位置へ容易に戻すことができる。 The mounting unit 10 can be easily moved from the fourth predetermined position to the third predetermined position. In this case, since the lock member 17a can be rotated counterclockwise around the shaft 17d by the spring member 17c, the lock member 17a is in contact with the end face of the engagement hole 10f, and the lock member 17a is rotated counterclockwise. And is retracted from the engagement hole 10f. Therefore, since the lock member 17a and the engagement hole 10f do not interfere with each other, the mounting portion 10 can be easily returned from the fourth predetermined position to the third predetermined position.

また、搭載部７が第四の所定位置においては、搭載部７及びこれに搭載された入浴者の重心が偏ってしまって不安定な状態となっているので、上記のように搭載部７が第三の所定位置へ戻されることにより、搭載部７および入浴者の態勢を安定化して入浴者の安全を確保することができる。 Further, at the fourth predetermined position of the mounting portion 7, the center of gravity of the mounting portion 7 and the bather mounted thereon is biased to be in an unstable state, and thus the mounting portion 7 is as described above. By returning to the third predetermined position, the mounting portion 7 and the position of the bather can be stabilized to ensure the safety of the bather.

第二の移動阻止機構部１８において、その重心は、軸１８ｃに位置するように設定されている。これにより、台車部９が例えば凹凸のある床面上を通過して上下方向に衝撃力を受けた場合でも、第二の移動機構部１８が軸１８ｃを中心として回転することを防止することができるので、ロック部材１８ｂが時計回りに回転してロック部材１８ｂと係合部１０ｄとの係合が外れることを防止することができる。 The center of gravity of the second movement prevention mechanism 18 is set to be located at the axis 18 c. As a result, even when the carriage portion 9 passes an uneven floor surface and receives an impact force in the vertical direction, for example, the second moving mechanism unit 18 is prevented from rotating about the shaft 18c. Since this can be performed, it is possible to prevent the lock member 18b from rotating clockwise and disengaging the lock member 18b from the engagement portion 10d.

第二の移動阻止機構部１８の重心の位置は上記に限定されることなく、例えばロック解除部材１８ａ側にあってもよい。この場合、第二の移動阻止機構部１８には軸１８ｃを中心として反時計回りに回転しようとする力が作用しているので、ロック部材１８ｂを時計回りに付勢しているバネ部材１８ｄが劣化してその付勢力が弱くなっていても、ロック部材１８ｂが時計回りに回転してロック部材１８ｂと係合部１０ｄとの係合が外れることを防止することができる。 The position of the center of gravity of the second movement prevention mechanism 18 is not limited to the above, and may be on the side of the unlocking member 18a, for example. In this case, since the second movement preventing mechanism 18 is acting to rotate counterclockwise around the shaft 18c, the spring member 18d biasing the lock member 18b clockwise is It is possible to prevent the locking member 18b from rotating clockwise and disengaging the engagement between the locking member 18b and the engaging portion 10d even if the biasing force is deteriorated due to deterioration.
