Description

  The present invention relates to a bathing apparatus.

  In the past, a bathing device was developed that allows bathers to soak in the hot water in a bathtub while being placed on a stretcher for the purpose of bathing those who need assistance (needed assistants) such as sick people, elderly people, physically disabled people, etc. (See, for example, Patent Document 1).

  In the bathing device disclosed in Patent Document 1, a bather is transferred from a stretcher placed on a bathtub onto a carrier in a bathtub together with a stretcher. When the stretcher is transferred onto the support, the door on the side of the tub is closed, and a suitable amount of hot water is stored in the tub. Thereafter, the carrier can be immersed in the hot water up to the shoulder by tilting the carrier from the horizontal position. In addition, the pedestal is inclined so that the buttocks side is lower than the foot side of the bather who has been placed on the stretcher.

JP 2008-278980 A

  By the way, in the bathing apparatus in which the carrier is inclined and bathed, the carrier is also inclined together with the carrier. For this reason, depending on the configuration of the bathing apparatus, a situation may occur where the tip of the bather on the stretcher comes out of the hot water by tilting the carrier. When the feet come out of the hot water, the bather can not be warmed sufficiently, so the occurrence of such a situation is not preferable.

  In view of the above, it is an object of the present invention to provide a technique for allowing a bather to comfortably bathe in a bathing apparatus for letting a bather on a stretcher take a bath by tilting the carriage.

  In order to achieve the above object, a bathing apparatus according to the present invention comprises a stretcher including a first frame portion and a second frame portion rotatably attached to the first frame portion, and a bather mounted on the stretcher A tub for storing hot water into which the water is to be immersed, a carrier provided so as to be able to fix the first frame portion, on which the stretcher is placed, tilt means for changing the tilt angle of the carrier, and driving of the tilt means. And a restricting means for restricting the rotation of the second frame portion with respect to the first frame portion in a predetermined direction.

  According to this configuration, the second frame portion is made the first frame portion by changing the inclination angle of the carrier (on which the first frame portion is fixed) on which the stretcher is mounted using the tilt means. The stretcher can be deformed by rotating (relatively rotating). And since the control means which controls the direction of rotation with respect to the 1st frame part of the 2nd frame part accompanying drive of a tilt means is provided, the 2nd frame part is turned in the opposite direction to a plan direction. It is possible to avoid that the movement of the stretcher is inconvenient. That is, according to this configuration, a bather can be made to bathe comfortably.

  In the bathing apparatus of the first configuration, when the support means is moved in the direction in which the tilt angle is increased by the tilt means, the restricting means performs rotation of the second frame part with respect to the first frame part. Preferably, the configuration (second configuration) includes first regulation means for regulating movement in a first direction. According to this configuration, it is possible to prevent the occurrence of inconvenience when the tilt of the carrier support is increased by the tilt means.

  In the bathing apparatus of the second configuration, the first direction is a direction opposite to a direction in which the second frame portion tries to rotate with respect to the first frame portion by the buoyancy received from the hot water of the bath. The configuration (third configuration) is preferable. According to this configuration, it is possible to avoid the occurrence of a situation in which the second frame portion does not deform due to the buoyancy.

  In the bathing apparatus according to any one of the first to third configurations, when the support means is moved by the tilt means in the direction in which the inclination angle is reduced, the restriction means sets the second frame portion It is preferable that it is a structure (4th structure) in which the 2nd control means which controls rotation with respect to the flame | frame part of 1 in 2nd direction is included. According to this configuration, it is possible to prevent the occurrence of inconvenience when the tilt of the carrier support is reduced by the tilt means. The second direction is the direction opposite to the above-described first direction.

  In the bathing apparatus according to any one of the first to fourth configurations, the restriction means includes a member provided on the stretcher, and a member provided on a support that rotatably supports the pedestal. It may be configured (fifth configuration). According to this configuration, the restricting means can be realized simply and at low cost.

  In the bathing apparatus according to any one of the first to fifth configurations, the second frame portion preferably constitutes a portion on which a toe of a bather is placed (sixth configuration). In this configuration, since the stretcher can be appropriately deformed in accordance with the tilt change of the carrier by the tilt means, it is possible to prevent the trouble that the toe comes out of the hot water when the bather is immersed in the hot water it can. Note that the first frame portion preferably constitutes a portion on which the upper side of the body is to be mounted than the portion to be placed on the second frame portion, and the second frame portion of the first frame portion is attached On the other side, a third frame part (e.g. a backrest part) may be rotatably mounted.

  In the bathing apparatus according to any one of the first to sixth configurations, the bathtub is provided so as to be capable of moving up and down, and the pedestal can be switched between being in the bathtub and being out of the bathtub The configuration may be provided (seventh configuration). According to the present configuration, after the stretcher (on which the bather is placed) is placed on the carrier, it is not necessary to store the hot water, and it is easy for the bather to take a bath comfortably.

  According to the present invention, it is possible to provide a technique that allows a bather to comfortably bathe in a bathing apparatus for letting a bather who is on a stretcher take a bath by tilting the carrier.

<The bathing device of the prior development>

  FIG. 1 and FIG. 2 are side views schematically showing the bathing apparatus 100 of the prior development. FIG. 1 is a view showing a standby state before a bather is allowed to bathe. FIG. 2 is a view showing a state in which a bather is caused to bathe. In FIG. 1 and FIG. 2, when the bathing apparatus 100 is viewed from the side, a portion which is not originally visible is drawn so as to be partially visible.

  As shown in FIG. 1 and FIG. 2, the bathing apparatus 100 of the prior development includes a gantry 1 fixedly disposed on a floor F, and a bathtub 2 disposed on the gantry 1. In addition, the bathing apparatus 100 includes a stretcher (not shown) in FIGS. 1 and 2. The bather is immersed in the hot water stored in the bathtub 2 while being placed on a stretcher.

  A column 11 extending vertically (vertically) is erected on the gantry 1. The column 11 penetrates the bottom wall 21 of the bathtub 2 in a liquid tight manner. The bathtub 2 is provided to be able to move up and down along the column 11. The raising and lowering of the bathtub 2 is performed by raising and lowering means (not shown) provided on the gantry 1.

  In addition, although the structure of a raising / lowering means is not specifically limited, In the bathing apparatus 100, a raising / lowering means is comprised using X link mechanism and a raising / lowering cylinder (for example, hydraulic cylinder). The expansion and contraction of the piston of the elevating cylinder causes the X link mechanism to expand and contract in the vertical direction, and the expansion and contraction of the X link mechanism causes the bathtub 2 to move up and down. FIG. 1 shows the state in which the bathtub 2 is lowered to the lowermost position, and FIG. 2 shows the state in which the bathtub 2 is raised to the uppermost position.

  A support frame 12 (an example of a support portion of the present invention) is fixed to the upper surface portion of the support 11. The support frame 12 extends largely from one of the columns 11 toward one side in the longitudinal direction of the bathtub 2 (the side on which the foot is disposed), and rotatably supports a carrier frame 13 on which a stretcher is placed. The center of rotation is fixed to the support frame 12 and connected to one end of the carriage 13 (one end in a direction parallel to the longitudinal direction of the bath 2, the left end in FIGS. 1 and 2) The shaft 14 is responsible. The carrier frame 13 changes the inclination angle by rotating around the shaft 14.

  The lower end side of the carriage 13 is connected to the tip end side of a piston 31 of a tilt cylinder 3 (an example of the tilt means of the present invention) configured by, for example, a hydraulic cylinder. The body portion of the tilt cylinder 3 is fixedly disposed in a column 11 provided hollow. The piston 31 of the tilt cylinder 3 penetrates the upper surface of the support 11 in a fluid-tight manner and protrudes from the upper surface of the support 11. By the variation of the amount of projection of the piston 31 from the upper surface of the column 11, the carriage 13 rotates about the shaft 14 to change its inclination angle. In addition, FIG. 1 has shown the state (inclination angle 0 degree) in which the support base 13 is horizontal. FIG. 2 shows a state in which the pedestal 13 is inclined from the horizontal by a predetermined angle.

  In addition, a rail 131 for movably supporting a stretcher is provided on the upper surface of the carriage 13. The rail 131 extends in a direction perpendicular to the longitudinal direction of the bathtub 2 (in the direction perpendicular to the paper surface in FIGS. 1 and 2).

  Next, using the bathing apparatus 100 configured as described above, the operation of the bathing apparatus 100 when a bather takes a bath will be described with reference to FIGS. 3 to 5 in addition to FIGS. 1 and 2. Do. 3 to 5 are schematic side views for explaining the operation of the bathing apparatus 100 of the prior development. FIG. 3 is a diagram in which a stretcher 4 on which a bather M is placed is added to FIG. FIG. 5 is a diagram in which a stretcher 4 on which a bather M is placed is added to FIG. FIG. 4 is a diagram showing a state in the middle of transitioning from the state of FIG. 3 to the state of FIG.

  When the bather M takes a bath using the bathing apparatus 100, as shown in FIG. 1, the bathtub 2 is lowered to the lowest position, and the pedestal 13 is horizontal. In this state, the pedestal 13 is positioned slightly higher than the upper edge of the bathtub 2 (outside the bathtub). Further, in a state in which the carriage stand 13 is in the horizontal posture, the piston 31 of the tilt cylinder 3 largely protrudes from the upper surface of the support 11.

  Next, a stretcher (not shown) on which a stretcher 4 (with the bather M resting) is placed on the side surface (longitudinal side surface) of the bathtub 2 in the state shown in FIG. Then, as shown in FIG. 3, the stretcher 4 on the stretcher is transferred from the side surface of the bathtub 2 to the carriage 13. Rollers R 1 and R 2 are attached to the lower side of the stretcher 4, and the stretcher 4 is transferred to the carriage 13 by rolling the rollers R 1 and R 2 along the rail 131.

  The roller R1 is in contact with the upper surface of the rail 131, and the roller R2 is in contact with the side surface of the rail 131. Further, the stretcher 4 is fixed to the support frame 13 by a lock mechanism (not shown) so that the stretcher 4 transferred to the support frame 13 does not fall off.

  When the stretcher 4 is placed on a predetermined position of the carriage 13, the bathtub 2 is raised to the uppermost position by lifting means (not shown). As a result, as shown in FIG. 4, the carriage 13 on which the stretcher 4 is placed enters the bathtub from the outside of the bathtub. Under the present circumstances, although the stretcher 4 also enters in a bathtub, the bather M who mounted on the stretcher 4 has many hot water parts out of the hot water only by one part being immersed in hot water. That is, the bather M has not obtained a sufficient bathing state.

  When the bathtub 2 is raised to the uppermost position, next, the piston 31 of the tilt cylinder 3 is contracted, and the carrier frame 13 on which the stretcher 4 is mounted is, as shown in FIG. Degrees). When the carriage 13 tilts, the stretcher 4 also tilts. At this time, the portion of the stretcher 4 on which the upper body side of the bather M is placed is pushed by the bottom wall of the bath 2 and bent. For this reason, by tilting the pedestal 13, the bather M can be soaked in the hot water up to the shoulder while avoiding the head of the bather M from entering the hot water.

  According to the bathing apparatus 100, in order to make the carriage stand 13 be inclined from horizontal attitude using the tilt cylinder 3, soaking the bather M in hot water to the shoulder while suppressing the amount of raising the bathtub 2 Is possible. For this reason, even a short assistant can easily perform assistance work while taking a bath. At the time of bathing, the reverse operation to the above is performed.

By the way, the stretcher 4 in the bathing apparatus 100 of the prior development has a configuration in which the toe of the stretcher 4 does not bend in consideration of the safety of the bather M and the like. For this reason, when the carrier frame 13 changes from the horizontal posture to the inclined posture, as shown in FIG. 5, the feet of the bather M may get out of the hot water. If the feet come out of the hot water, the bather M can not warm his body sufficiently and can not take a comfortable bath. The bathing apparatus according to the embodiment of the present invention has a device for improving such a point. Hereinafter, a bathing apparatus according to an embodiment (the present embodiment) of the present invention will be described.
<A bathing apparatus of the present embodiment>

  The bathing apparatus of the present embodiment is different from the bathing apparatus 100 of the prior development only in the configuration of a part of a stretcher for carrying a bather, and the configuration of a carrier and a part around the carrier on which the stretcher is mounted. For this reason, the description will be focused on parts different from the bathing apparatus 100 of the prior development. Moreover, about the part which overlaps with the bathing apparatus 100 of prior development, the same code | symbol is attached | subjected, and the description is abbreviate | omitted, when it is not necessary to demonstrate in particular.

  FIG. 6 is a schematic perspective view showing a part of the stretcher 4 provided in the bathing apparatus according to the embodiment of the present invention in an enlarged manner. The stretcher 4 includes a base frame portion 41 and a leg frame portion 42 rotatably provided with respect to the base frame portion 41. The base frame portion 41 is an example of the first frame portion of the present invention, and the leg frame portion 42 is an example of the second frame portion of the present invention. Further, a cover member (not shown) is appropriately attached to the base frame portion 41 and the leg frame portion 42.

  The base frame portion 41 includes two types of rollers R1 and R2 engaged with the rails 131 provided on the carriage 13 and is provided so as to be fixed to the carriage 13. A backrest frame 43 (see FIG. 9 described later) is rotatably attached to the base frame 41 on the side opposite to the side where the leg frame 42 is attached.

  The leg frame portion 42 mainly constitutes a portion on which the feet of the bather M can be placed. The leg frame portion 42 includes a leg portion rotation support shaft 421 rotatably supported by the base frame portion 41. That is, the leg frame portion 42 is rotatable with respect to the base frame portion 41 with the leg rotation support shaft 421 as a center. In order to exert the function as the stretcher 4, it is desirable that the leg frame portion 42 generally extend substantially straight from the base frame portion 41 as shown in FIG. For this purpose, locking means 50 is provided so that the leg frame portion 42 does not pivot downward (in the X1 direction in FIG. 6) by the action of gravity.

  Although the leg frame portion 42 can be slightly rotated in the direction of arrow X2 in FIG. 6 (the direction in which the leg frame portion 42 is lifted), the amount of rotation is limited by the collision with the base frame portion 41. ing.

  As shown in FIG. 6, the lock means 50 includes a first lock piece 51 fixed to one end of a lock release pivoting support shaft 411 rotatably supported by the base frame portion 41, and a leg portion rotation. And a second lock piece 52 fixed to one end of the movable support shaft 421 (the end on the same side as the first lock piece 51 is provided). When the leg frame portion 42 extends substantially straight to the base frame portion 42 (the state shown in FIG. 6 is applicable), one side of the first lock piece 51 and one side of the second lock piece 52 And abut. For this reason, even if the leg frame portion 42 tries to rotate by the action of gravity, the rotation of the second lock piece 52 is interrupted by the first lock piece 51. Therefore, in the state shown in FIG. 6, the leg frame portion 42 is not pivoted downward (X1 direction) by the action of gravity.

  Although the first lock piece 51 is provided at one end of the lock release pivot support shaft 411, it may be provided at both ends depending on circumstances. In addition, the second lock piece 52 is provided at one end of the leg rotation support shaft 421, but may be provided at both ends depending on the case.

  The bathing apparatus of the present embodiment, as shown in FIG. 6 and FIG. 7, includes lock release means 60 for releasing the lock by the lock means 50 when the stretcher 4 is placed on the carriage 13. The unlocking means 60 is provided not only on the support 4 but also on the support 13 and the support 12 for supporting the support 13. In addition, FIG. 7 is a schematic perspective view which shows the periphery structure of the carrier-support 13 with which the bathing apparatus which concerns on embodiment of this invention is equipped.

  As shown in FIG. 6, the unlocking means 60 includes a lifting dock 61 provided at a substantially central portion in the width direction of the leg frame portion 42 provided in a substantially rectangular shape. The lifting dock 61 protrudes from the lower surface of the leg frame portion 42. The lifting dock 61 is provided in a substantially trapezoidal frame shape in a side view, and on both side surface portions of the lower end portion 611, a pair of tongue portions 612 that project obliquely upward are provided.

  Further, as shown in FIG. 6, the unlocking means 60 includes an unlocking lever 62 provided substantially at the center of the unlocking pivot 411 in the width direction. The lock release lever 62 protrudes obliquely downward (in a direction toward the base frame portion 41) from the lock release pivot support shaft 411. The lock release lever 62 is provided in a round bar shape, and its tip is rounded.

  Further, as shown in FIG. 7, the unlocking means 60 includes a lifting block 63 provided on the projecting piece 121 projecting from one end of the support 12 in the longitudinal direction. The lifting block 63 is provided substantially in the shape of a truncated pyramid.

  Further, as shown in FIG. 7, the unlocking means 60 includes an unlocking block 64 provided on a projecting piece 132 projecting from one end of the carriage 13 in the longitudinal direction. The unlocking block 64 is provided in a substantially trapezoidal column.

  The lifting block 63 and the unlocking block 64 are both disposed at the center of the width direction of the bathtub 2 (the arrow Y direction in FIG. 7, the direction orthogonal to the paper surface in FIG. 1) as an example. However, the length of the lifting block 63 in the width direction of the bathtub 2 is larger than that of the unlocking block 64.

  FIG. 8 is a schematic side view for explaining the operation of the unlocking means 60 provided in the bathing apparatus according to the embodiment of the present invention. The operation of the unlocking means 60 will be described with reference to FIG. In FIG. 8A, the first lock piece 51 and the second lock piece 52 are in contact with each other, and the second frame portion 42 is not rotated with respect to the first frame portion 41 by the lock means 50. As locked. For example, when the stretcher 4 is placed on a stretcher, the locking means 50 is in the state shown in FIG. 8 (a).

  When the stretcher 4 on the stretcher is transferred from the side surface of the bathtub 2 to the pedestal 13, the tongue portion 612 of the lifting dock 61 hits the lifting block 63 during the transfer. When the transfer of the stretcher 4 is continued with both members in contact, the leg frame portion 42 is pivoted in the lifting direction (X2 direction in FIG. 6), and the lifting dock 61 is mounted on the lifting block 63. (See FIG. 8 (b)).

  When the lower end portion 611 (see FIG. 6) of the lifting dock 61 rests on the upper surface of the lifting block 63 and the leg frame portion 42 is lifted, a gap between the first locking piece 51 and the second locking piece 52 (See FIG. 8 (b)). Thereby, the first lock piece 51 can rotate. If the transfer of the stretcher 4 is further continued in this state, then the unlocking lever 62 strikes the unlocking block 64. When the transport is further continued in this state, the unlocking lever 62 is pushed up to the unlocking block 64. As a result, the first lock piece 51 is rotated (rotated in the X1 direction in FIG. 6) together with the lock release pivot support shaft 411 (see FIG. 6), and the rotation of the second lock piece 52 is the first The state blocked by the lock piece 52 is eliminated (see FIG. 8C). That is, the lock by the lock means 50 is released.

  In addition, in the state to which transfer of the support 4 to the support stand 13 was completed, the lock means 50 and the lock release means 60 will be in the state shown in FIG.8 (c). In the state shown in FIG. 8C, the lifting dock 61 is placed on the lifting block 63. For this reason, even when the lock by the lock means 50 is released, the leg frame portion 42 does not immediately rotate relative to the base frame portion 41.

  When the carrier 13 is changed from the horizontal posture to the inclined posture using the tilt cylinder 3 in the state shown in FIG. 8C (that is, the state where the transfer of the support 4 to the carrier 13 is completed), Since the lock is released, the leg frame portion 42 rotates relative to the base frame portion 41. In detail, of the base frame portion 41 and the leg frame portion 42, only the base frame portion 41 moves in the same manner as the carriage 13. Then, the leg frame portion 42 is turned relative to the base frame portion 41 by the action of gravity and is in a bent state (see FIG. 8D). In the present embodiment, even in this state, the leg frame portion 42 is supported by the lifting block 63.

  As a result, as shown in FIG. 9, in the present embodiment, it is possible to suppress a situation in which the toe of the bather M placed on the leg frame portion 42 comes out of the hot water in the bathtub 2. When the carriage 13 is returned from the inclined posture to the horizontal posture, and the carriage 4 is transferred from the carriage 13 to the stretcher, the locking means 50 and the unlocking means 60 perform the reverse operation to the above. FIG. 9 is a side view schematically showing the bathing state of the bather M in the bathing apparatus according to the embodiment of the present invention.

  By the way, when the carriage frame 13 is tilted from the horizontal state, the leg frame portion 42 may not be properly bent downward due to the buoyancy received from the hot water stored in the bathtub 2. If the leg frame 42 is not properly bent downward, the toe of the bather M may get out of the hot water. For example, in the case where a cover formed by blow molding or the like is attached to the leg frame portion 42, the influence of the buoyancy is likely to be exerted.

  Therefore, in the present embodiment, as shown in FIG. 10, when the pedestal 13 is tilted from the horizontal state, the first rotation of the leg frame 42 with respect to the base frame 41 is restricted in the first direction. A regulation means 70 is provided. The first direction is a counterclockwise direction in FIG. 10, which is the direction opposite to the direction in which the leg frame portion 42 rotates with respect to the base frame portion 41 by the buoyancy received from the hot water in the bathtub 2.

  In addition, FIG. 10 is a schematic side view for demonstrating the control means with which the bathing apparatus concerning embodiment of this invention is provided. FIG. 10 shows a state in which the transfer of the support 4 to the carrier 13 is completed (the same state as FIG. 8 (c)). In the state shown in FIG. 10, the carriage 13 is horizontal (inclination angle 0 °).

  The lifting dock 61 and the lifting block 63 in FIG. 10 are slightly different in shape from those described above, but their actions are substantially the same, so detailed description will be omitted. However, in the configuration shown in FIG. 10, a recess is provided in the upper portion of the lifting block 63. Under this influence, in a state where the stretcher 4 is arranged at a predetermined position (a state where the transfer of the stretcher 4 to the carriage 13 is completed), the leg frame portion 42 extends straight from the base frame portion 41 in a substantially horizontal direction. It is in the state of taking out.

  As shown in FIG. 10, the first restricting means 70 includes a round bar-like member 71 fixed to the lifting dock 61 of the stretcher 4. The rod-like member 71 extends in the direction perpendicular to the paper surface in FIG. Further, the first restricting means 70 includes a bending member 72 obtained by bending a plate-like member. The bending member 72 is fixed to a support 12 (more specifically, a portion extending from the support 12) for supporting the carriage 13.

  FIG. 11 is a schematic plan view of the rod-like member 71 and the bending member 72 constituting the first restricting means 70 as viewed from above. As shown in FIGS. 10 and 11, the bending member 72 is disposed so as to cover the rod-like member 71 by the inclined portion 72a. As shown in FIG. 11, the bent portion 72 is provided with a notch 72 b in order to prevent the lifting dock 61 from colliding with the bending member 72.

  FIG. 12 is a schematic side view for explaining the operation of the restricting means provided in the bathing apparatus according to the embodiment of the present invention. Fig.12 (a) is a figure which shows the state which the support base 13 inclined about 10 degrees from the state shown in FIG. FIG.12 (b) is a figure which shows the state which the support base 13 inclined about 20 degrees from the state shown in FIG.

  When the carrier frame 13 in the horizontal state starts tilting, the rod-like member 71 comes in contact with the bending member 72 as shown in FIG. 12 (a). For this reason, when increasing the inclination angle of the carriage 13, even if buoyancy is applied to the leg frame portion 42, the rotation of the leg frame portion 42 with respect to the base frame portion 41 bends downward (FIG. 12) In the counterclockwise direction). Therefore, as shown in FIG. 12 (b), when the inclination of the pedestal 13 is increased, the leg frame portion 42 is sufficiently bent relative to the base frame portion 41, and the toe of the bather M is It can prevent getting out of the hot water.

  In order to return the carriage support 13 from the inclined state shown in FIG. 12 (b) to the horizontal state shown in FIG. 10, the base frame of the leg frame portion 42 in order for the lifting dock 61 to abut the lifting block 63. The rotation with respect to the portion 41 is restricted in the upward direction (clockwise direction in FIG. 12). Therefore, as the inclination angle of the carriage 13 is reduced, the leg frame portion 41 returns to the state of extending almost straight with respect to the base frame portion 41.

The upward direction described above is opposite to the restriction direction by the first restriction means 70, and corresponds to the second direction of the present invention. That is, the lifting dock 61 and the lifting block 63 restrict rotation of the leg frame portion 42 with respect to the base frame portion 41 in the second direction when moving the carriage 13 in the direction in which the inclination angle decreases. 2 It can be said that it is the regulation means 80.
<Others>

  The embodiments described above are merely illustrative of the present invention. The configurations of the embodiments described above may be modified as appropriate without departing from the technical concept of the present invention.

  For example, when the carriage 13 is moved in the direction in which the tilt angle is increased, the first restricting means restricts the rotation of the leg frame 42 with respect to the base frame 41 in the first direction (counterclockwise in FIG. 10). Alternatively, a tension spring 90 as shown in FIG. 13 may be used.

  In FIG. 13, one end of the tension spring 90 is attached to a part of the leg frame portion 42, and the other end is attached to the unlocking pivot 411 that is supported by the base frame portion 41. The tension spring 90 regulates the direction in which the leg frame portion 42 pivots in the X1 direction (first direction) in FIG. 13 when the carriage support 13 is changed from the horizontal posture to the inclined posture by the biasing force thereof. Do. The number and attachment positions of the tension springs 70 may be changed as appropriate.

  Moreover, although the hydraulic cylinder was utilized as a tilting means in the above, this is only an example. The tilt means may be configured using, for example, a screw driven by a motor.
