Detailed Description

Hereinafter, modes for carrying out the present invention will be described with reference to the drawings. The embodiment shown below is an embodiment of the present invention, and the present disclosure is not limited to the following description. In the following description, brackets are sometimes used, but the terms in the brackets are not necessarily the same as the terms described before the brackets.

For example, it is known to provide casters at a lower portion for facilitating movement of a moving device such as a table by a user. However, due to the presence of casters, the table or the like may be moved unintentionally. Therefore, in order to restrict the movement of the table, it is performed to provide a locking mechanism so that the casters do not move.

In order to operate the locking mechanism in a locked/unlocked state (unlocked) state, an operation mechanism is provided. For example, a method of providing an operating mechanism at the upper portion of the table may be considered. In this case, the user has an operation mechanism at his/her hand, and the user performs an operation related to locking at his/her hand, so that convenience is high. However, there is an operating mechanism (e.g., lever for operation) within reach of the user's hand, which may cause the user to operate the operating mechanism unintentionally. This causes a problem that the user unintentionally releases the lock. In addition, if the operation mechanism is provided at the upper portion of the table, an operation transmission means from the operation mechanism located at the upper portion of the table to a locking mechanism (for example, a brake of a caster) provided at the lower portion of the table is additionally required, and there is a problem that the cost increases.

In addition, as another method, it is performed that a pedal (lock pedal) is provided on the caster itself as an operation means for locking the caster. In this case, since the lock pedal is generally the same size as or smaller than the caster, there is a problem in that it is difficult for the user to perform the locking operation. Further, a lock pedal is provided for each caster, and it is necessary to perform an operation one by one in order to lock or unlock all casters.

Further, as the operation mechanism, there is an operation mechanism in which a pedal for locking casters is attached to a side surface of a table leg. In this case, the pedal protrudes from the table leg, and when the table is moved, the pedal collides with a wall or other device (e.g., a bed device, etc.), resulting in a problem of damage.

Further, there is a problem in that an operating mechanism for operating the pedal is provided above the table leg, but the pedal is constructed so as to be laterally moved, and thus the pedal is difficult to operate with the leg. In addition, in the case of a table in which an operation pedal for a stepping operation (vertical rotation) is located above a table foot, the user needs to raise the foot high in order to operate the operation pedal, and thus there is a problem in that unbalance is likely to occur.

In view of one or more of these problems, a technique for solving these problems, conventional problems, and the like will be described below with an embodiment as an example. The following embodiments are one method for solving these problems and conventional problems, and the like, and are not limited to the methods described in the following embodiments. The object of the present disclosure in the specification is not limited to this, and the present disclosure also has the meaning of acquiring rights by divisional application, correction, and the like for the purpose of obtaining effects from the parts of the structure disclosed in the specification, the drawings, and the like.

[1 ] embodiment ]

[1.1 Structure of Table as a whole ]

Fig. 1 is a perspective view showing an external appearance of a table 1 as a mobile device provided with a lock mechanism and an operation mechanism for operating the lock mechanism. The table is connected to the top plate 10 and the base 20 by a brace 30. The support column 30 has an adjusting mechanism capable of adjusting the height. When the user operates the lever 12, for example, the lock of the adjustment mechanism is released, and the length of the stay can be adjusted. The adjustment mechanism provided in the stay 30 may be any known technique.

In fig. 1, the F side of the table 1 is the front side, and the B side is the back side. The R side is referred to as the right side when the table 1 is viewed from the front, and the L side is referred to as the left side when the table 1 is viewed from the front. The FB direction is referred to as the front-rear direction (width direction) of the table 1, and the LR direction is referred to as the left-right direction (longitudinal direction) of the table 1.

Fig. 2 is a perspective view illustrating the base 20, and is a perspective view from above. The base 20 is provided with casters 202 at four corners of a lower end portion, for example. That is, casters 202 for moving the table 1 are provided at the lower portion of the table 1. The table 1 can be moved on the floor or the like by the casters 202.

The base 20 has an operating mechanism 22 for operating a locking mechanism provided to the caster 202. As an example, the operating mechanism 22 is provided at a position near the lower end of the stay 30, but is not limited to this position. The operating mechanism 22 is connected to the locking mechanism via a transmission mechanism.

A pedal 210 is provided as an operation means for performing an operation of the lock mechanism as a part of the operation mechanism 22 at an outer edge portion of the base 20. The pedal 210 is preferably provided on one side of the base 20 in the lateral direction, and is provided in the vicinity of the strut 30 in fig. 1.

In addition, the pedal 210 is provided to be longitudinally rotatable with respect to the base 20. That is, the pedal 210 is configured to be rotatable in the longitudinal direction, for example.

The user can operate the locking mechanism by depressing or kicking the pedal 210. The caster 202 can be unlocked or locked by the operation of the pedal 210. For example, rotation of the caster 202 (wheels constituting the caster 202) is inhibited by a stopper member provided to the caster 202. A state in which the caster 202 is locked by the locking mechanism, for example, the wheel of the caster 202 does not move is referred to as a locked state.

Thus, when the pedal 210 is depressed by the user, the plurality of casters 202 provided below the table 1 (base 20) are locked, and the movement of the table 1 is restricted. At this time, it is preferable that when the user depresses the pedal 210, the plurality of casters 202 provided to the base 20 are brought together into a locked state.

Further, for example, when the user kicks the pedal 210, the plurality of casters 202 are in a freely movable state (a state in which wheels of the casters 202 are freely rotated). Such a state in which the caster 202 is free to move is referred to as an unlocked state.

That is, the user can easily operate to free or stop (prohibit) the movement of the table 1 by using the operation mechanism 22 provided to the base 20.

Further, the structure of the base 20 will be described with reference to fig. 2 and 3. Fig. 3 is a perspective view from the bottom surface of the base 20.

The base 20 is a case structure formed with an opening facing the back surface side, and constitutes a leg. The base 20 is a hollow casing that covers the operating mechanism and the transmission mechanism on the front side, the right side, and the left side of the table 1. That is, the table 1 has a shape of コ when viewed from above. The opening of the base 20 faces a user (e.g., a patient, a care recipient, etc.) of the table 1. Therefore, the user can put the wheelchair into the opening or can arrange a normal chair on the table 1.

Casters 202 (casters 202A, 202B, 202C, 202D) having a locking mechanism are provided at four corners of the base. In the present embodiment, the casters 202 are provided near the four corners, but may be further provided. The caster 202 is preferably located near the corner of the base 20, but may not necessarily be located near the corner.

The base 20 may be provided with a mounting member 206 (e.g., a top plate) at a position where the caster is mounted. The mounting member 206 is fixed to the base 20, for example. In addition, the mounting member 206 may have a structure (e.g., a screw hole) for mounting the caster 202. For example, the body portion (fork) of the caster 202 and the mounting member 206 are mounted so as to be rotatable. The caster 202 is rotatably provided with wheels via an axle near the tip of the main body.

In addition, the caster 202 preferably has a locking function. The locking mechanism is a mechanism that locks the rotation of the wheels of the caster 202. For example, the caster 202 may have a stopper fitting as a locking member, and the stopper fitting locks the rotation of the wheel.

The caster 202 may be provided with a locking member having a protruding portion between the wheels. In this case, a plurality of concave portions are provided on the inner side of the wheel. Further, the locking member having the protruding portion may be moved to fit the protruding portion into the recessed portion on the inner side of the wheel, thereby locking the rotation of the wheel. Other known mechanisms may be used as long as the mechanism locks the rotation of the wheels of the caster 202.

The locking mechanism of the caster 202 may be a mechanism that stops rotation of the wheel by another method without locking the wheel itself of the caster. For example, a braking member may be provided on the base 20, and the movement of the table 1 may be restricted by bringing the braking member into contact with the ground.

A wire 204 is connected to the locking mechanism of the caster 202 as a transmission mechanism for transmitting an operation (force) from the operation mechanism 22. The wire 204 connects the locking mechanism of the caster 202 with the operating mechanism 22. For example, when the user depresses the pedal 210 of the operating mechanism 22, the wire 204 is stretched by the operating mechanism 22, and tension is applied to the wire 204. The wheels of the caster 202 are locked by the locking mechanism by applying tension to the wire 204. That is, the table 1 is shifted from the lock released state to the lock state.

In addition, for example, when the user kicks up the pedal 210 of the operating mechanism 22, tension applied to the wire 204 is no longer applied, and the locking of the wheels of the caster 202 is released by the locking mechanism. That is, the table 1 is shifted from the locked state to the unlocked state. In addition, the wire 204 may also be housed within the tube 28 in the base 20.

The base 20 may be formed with a bulge 242 so as to bulge outward toward one side in the left-right direction (horizontal direction in plan view) of the table 1.

[1.2 description of operating mechanism ]

Next, the operation of the operation mechanism 22 will be described. Fig. 4 is a diagram schematically illustrating the operation of the operating mechanism 22 and the locking mechanism of the caster 202.

The operation of the caster 202 in the locked state will be described with reference to fig. 4. Fig. 4 (a) is a diagram showing the state of the operating mechanism 22 when the caster 202 is in a locked state, that is, when the wheels of the caster 202 have been locked by the locking mechanism 203. Fig. 4b is a diagram showing the state of the operating mechanism 22 when the caster 202 is in the unlocked state, that is, when the wheels of the caster 202 are free to rotate (the lock has been released) by the locking mechanism.

The operating portion 220 of the operating mechanism 22 is connected to the pedal 210 via the support shaft 212. One end of the fulcrum 212 is connected to the center of rotation of the pedal 210. The other end of the support shaft 212 is connected to a cam 222 of the operation unit 220. Thus, when the pedal 210 is rotated, the cam 222 is also rotated via the fulcrum 212.

A frame-shaped slider 224 is disposed around the cam 222 so as to contact the cam 222. When the pedal 210 is rotated (for example, the user depresses the pedal 210A in the pedal 210), the cam 222 rotates in conjunction with the movement of the tip of the cam 222 from the L1 direction to the R1 direction. When the tip of the cam 222 rotates from the L1 direction to the R1 direction, the abutting slider 224 also moves from the L1 direction to the R1 direction. That is, the cam 222 functions as a driving member. The slider 224 in contact with the cam 222 functions as a follower.

The slider 224 is connected to the housing of the operation unit 220 at one end (R1 side) and to the wire 204 at the other end (L1 side). In fig. 4, one end side (R1 side) of the slider 224 is connected to a housing of the operation unit 220 via an elastic body (e.g., a spring 226). By the movement of the slider 224 in the R1 direction, a force is applied to the spring 226, and the spring is deformed into a contracted state.

The slider 224 is connected to the wire 204 via an elastic body (e.g., a spring 228) at the other end (L1 side).

When the slider 224 moves from the L1 side to the R1 side as described above, the spring 228 is extended, and the tension is applied to the wire 204 as a whole. That is, the wire 204 is stretched by the operation unit 220.

The locking mechanism 203 locks the wheels of the caster 202 by applying tension to the wire 204. Thereby, the caster 202 is shifted to the locked state.

Thus, the slider 224 is connected to each of the lock mechanisms 203. For example, the slider 224 is connected to the locking mechanism 203A of the caster 202A via a spring 228 and a wire 204A. Similarly, the slider 224 is connected to the lock mechanism 203B of the caster 202B via the spring 228 and the wire 204B, the slider 224 is connected to the lock mechanism 203C of the caster 202C via the spring 228 and the wire 204C, and the slider 224 is connected to the lock mechanism 203D of the caster 202D via the spring 228 and the wire 204D. Thus, the pedal 210, cam 222, slide 224, and locking mechanism 203 are linked.

Here, since the positions where the casters 202 are provided are different, the lengths of the wires 204 connected to the locking mechanisms 203 of the casters 202 are different. Here, a spring 228 as an elastic body is provided between the wire 204 and the slider 224 so that a force is uniformly applied to the lock mechanism 203.

Fig. 4 (b) shows a state in which the locking of the caster 202 has been released. For example, when the pedal 210 is kicked (a portion where the pedal 210A is kicked) by the user, the cam 222 moves from the R1 direction to the L1 direction in conjunction with the rotation of the pedal 210. At this time, the slider 224 moves from the R1 direction to the L1 direction while abutting against the cam 222 due to the reaction force of the spring 226 contracted in fig. 4 (a). Since the spring 228 is in an extended state, the slider 224 may be moved from the R1 direction to the L1 direction by the reaction force of the spring 228.

Since the slider 224 moves from the R1 direction to the L1 direction, the tension applied to the wire 204 is no longer applied. Thus, the wire 204 is no longer pulled by the slider 224, the lock of the lock mechanism 203 of the caster 202 is released, and the caster 202 is shifted to the unlocked state.

That is, since the slider 224 moves in the L1 direction, a force in the opposite direction to the locking operation is applied to the locking mechanism 203 via the wire 204. For example, in the lock mechanism 203 of the caster 202, the convex portion of the lock member is separated from the concave portion of the caster 202.

Fig. 5 is a top view of the base 20, and is an enlarged view of a portion of the operating mechanism 22. Fig. 6 is a side view of the base 20, and is an enlarged view of a portion of the operating mechanism 22. Specifically, fig. 6 is a side view of the base 20 from the R side in fig. 1.

Fig. 6 (a) is a diagram showing the caster 202 in the unlocked state, and fig. 6 (b) is a diagram showing the caster 202 in the locked state. Here, the F side, B side, R side, and L side shown in fig. 5 and the F side and B side shown in fig. 6 correspond to fig. 1.

When the user depresses the pedal, the state of fig. 6 (a) is shifted to the state of fig. 6 (b). That is, when the user depresses the pedal 210A with his foot, the pedal 210 rotates, and the tip of the pedal 210A moves downward. When the user kicks up the pedal, the state of fig. 6 (b) is shifted to the state of fig. 6 (a). That is, when the user kicks up the pedal 210A with his foot, the pedal 210A rotates in the opposite direction to the direction of the depression, and the tip of the pedal 210A moves upward.

The bulge 242 is formed to bulge toward, for example, one end outer side (R side) in the left-right direction, and has a curved shape. Preferably, bulge 242 is disposed in the vicinity of pedal 210. That is, the bulge 242 may bulge the base 20 to a position including, for example, the center (rotation fulcrum) of the pedal 210. In this case, a notch 232 is formed between the front side and the front side of the bulge 242 and the base 20. In addition, the rear surface is provided with an inclined surface from the front surface in a side view.

The notch 232 is formed such that an outline 230, which is a virtual line in the case where the extension of the base 20 (bulge 242) extends from the back surface to the front surface, is located at a position including the pedal 210. That is, the notch 232 preferably ensures a size capable of accommodating the pedal 210.

By having the notch 232 in this manner, the user (e.g., a caregiver or the like) can operate the pedal 210 (210A) from the front side of the table. For example, when the desk 1 is brought close to a wheelchair in which a caretaker sits, many users such as caregivers are located on the front side of the desk. Therefore, the caregiver or the like can easily operate the pedal 210 from the front side.

In addition, by providing a space between the pedal 210 (210A) and the ground, the user can operate from the front side and the right side of the table 1 using the pedal 210 (210A). For example, when the caregiver inserts the table 1 into the bed being used by the caregiver, the caregiver is located on the right side of the table 1. In this case, the caregiver can easily operate the pedal 210 from the right side in addition to the front side.

In addition, since the pedal 210 has the pedal 210B, the user can perform the lock release operation using the pedal 210 from the rear surface side of the table 1. For example, when the care of the care-receiver is being performed, the care-receiver is located near the care-receiver, and thus the care-receiver is located on the back side of the table. At this time, the table 1 becomes an obstacle to nursing, and when the caregiver wants to move the table 1 slightly (for example, when the caregiver wants to return the feet of the person to be cared who is deviated from the footrest of the wheelchair), the user can operate the table 1 from the back side by using the pedal 210B.

In this way, the user can operate the lock mechanism by using the pedal 210, and thus can operate the lock mechanism from three directions as long as the lock mechanism is in the vicinity of the pedal 210.

In the present embodiment, the operation of the user to depress and kick up the pedal 210A in the pedal 210 is described, but the pedal 210B may be operated. At this time, contrary to the state of the pedal 210A, for example, when the pedal 210B is depressed, the state shifts from fig. 6 (B) to fig. 6 (a). Further, although the case where the user operates the pedal 210 with his foot is described as an example, the pedal 210 may be operated with his hand, for example. For example, when the user presses the pedal 210A by hand, the state transitions from fig. 6 (a) to fig. 6 (b). When the user lifts the pedal 210A by hand, the state of fig. 6 (b) is shifted to the state of fig. 6 (a).

As shown in fig. 5, the base 20 accommodates the operation unit 220 in the accommodation unit 234. The housing 234 is formed by a part of the base 20. The housing 234 is formed so as to ensure a space in which the operating unit 220 can be housed. The housing 234 is formed to house the (housing) operation part 220.

The operating unit 220 is connected to the pedal 210 via a support shaft 212. The housing 234 is formed to be higher than the base 20 except for the housing 234. This is only necessary if a sufficient height to accommodate the operation unit 220 can be ensured. Therefore, when the operation unit 220 is stored at the height of the base 20, the storage unit 234 may be configured in a state that it cannot be distinguished from the external appearance of the base 20 (a state that the height of the storage unit 234 is the same as the height of the entire base 20).

The bulge 242 may be formed in a space portion, and may be formed in a shape in which the pedal 210 (pedal 210B) enters the space portion. Fig. 6 (a) shows a state in which the pedal 210B that has moved downward when the pedal 210 is kicked up enters the space portion of the bulge portion 242.

Thus, the base 20 is preferably arranged such that the outer end of the pedal 210 is positioned inside the outer end of the base 20. The outer end of the base 20 may be formed into a bulge 242 by bulge of the shape of the base 20, and the outer end of the bulge 242 may be located outside the outer end of the pedal 210. In addition, the notch 232 may be provided so that the outer end of the pedal 210 is located inward of the contour line 230 as described above. By positioning the pedal 210 inside the outer end of the base 20, for example, when the table 1 is moved, the pedal 210 can be prevented from being broken by collision.

In addition, the pedal 210 has a pedal 210A and a pedal 210B. The pedals 210A and 210B are connected at a center 240 and are linked to the support shaft 212. For example, the pedal 210A and the pedal 210B may be fixed by screws or may be integrally formed.

The shape of the pedal 210 is preferably a structure and a height that can be depressed by a foot even in a state where the user's heel is in contact with the ground, so that the user can easily operate the pedal. The length of the pedal 210A is preferably 3cm or more as a structure that can be easily depressed. In addition, as the height of the pedal 210, considering the depression of the foot, it is preferable that the height be 9cm or less from the ground (the ground contact surface of the table 1) when the pedal 210A is directed upward.

In addition, a predetermined gap is preferably provided between the step 210 and the ground (the ground-contacting surface of the table 1). For example, it is preferable that there is a space to such an extent that the toe can enter the gap even in a state where the user wears the shoe. The user can easily kick the pedal 210 by entering the gap through the user's toes. For example, it is preferable that the top end of the pedal 210A be directed downward with a height of about 3cm to 8cm as the clearance. In the case where the base 20 (the inclined surface having the bulge 242) is provided below the pedal 210, it is preferable to provide a gap between the base 20 and the pedal 210 in the same manner.

In addition, the length of the pedal 210A is preferably longer than the pedal 210B. In the unlocked state, the length in the vertical direction of the pedal 210A (for example, the length in the vertical direction from the center 240 to the tip end portion of the pedal 210A) is preferably longer than the length T1 from the center 240 to the upper portion of the base 20.

In the locked state, the length in the vertical direction of the pedal 210B (for example, the length in the vertical direction from the center to the distal end portion of the pedal 210B) is preferably within the length T1.

The tip end portion of the pedal 210B may be configured not to exceed the upper end of the base 20 (or the upper end of the housing 234) when the caster 202 is in the unlocked state. For example, in fig. 6 (B), the pedal 210B is parallel to the surface of the upper end of the base 20. Therefore, the tip of the pedal 210B is configured not to exceed the upper end of the base 20.

That is, as a user, it is possible to confirm whether the caster 202 is in the locked state or the unlocked state by merely visually recognizing a portion protruding from the upper portion of the base 20. In particular, the table 1 according to the present embodiment can visually recognize whether all casters 202 are in the locked state, and can easily visually recognize that the table is not moved carelessly.

Fig. 7 is a side view of the base 20, and shows a state of being seen from the opposite side to fig. 6. That is, the portion of the operating mechanism 22 is shown from the L direction in fig. 1.

Fig. 7 (a) is a diagram showing the caster 202 in the unlocked state, and fig. 7 (b) is a diagram showing the caster 202 in the locked state. As shown in fig. 7 a, when the caster 202 is in the locked state, the upper side of the pedal 210 (pedal 210A) (the side of the end outward from the center of the pedal 210) protrudes from the upper portion of the base 20. In fig. 6 (a) and 7 (a), the top end of the pedal 210 (210A) is positioned above the height of the housing 234, so that the user can clearly confirm that the caster 202 is in the locked state. As shown in fig. 7 (b), when the caster 202 is in the unlocked state, the pedal 210 is hidden by the base 20. In fig. 6 (B) and 7 (B), the top end of the pedal 210 (210B) is positioned below the height of the housing portion 234, so that the user can clearly confirm that the caster 202 is in the unlocked state.

Further, the user can confirm that the caster 202 is in the locked state or the unlocked state from a remote position, depending on the positions of the base 20 and the pedal 210. That is, depending on the state of the pedal 210, the locked state and the unlocked state of the caster 202 can be easily checked, both when the user views the table 1 from above and when the user views the table 1 from a remote place. For example, the user can easily visually recognize that the table 1 is in an immovable state (for example, the casters 202 are all in a locked state) according to the position of the pedal 210. In addition, when the table 1 is configured such that a part of the casters 202 are locked as the table 1 cannot be moved, the user can easily visually recognize that the part of the casters 202 are locked according to the position of the pedal 210. When the braking member is used as the immovable state of the table 1, the user can easily visually recognize the case where the table 1 is immovable by the braking member according to the position of the pedal 210.

[2 ] other embodiments ]

Hereinafter, other embodiments of the above embodiment will be described in detail. The directions (F direction, B direction, L direction, R direction) shown in the drawings represent the same directions as those shown in fig. 1

[2.1 shape of pedal ]

Fig. 8 shows an embodiment using a pedal 310 instead of pedal 210. The operation unit 220 is accommodated in the accommodation portion 312 of the base 20. As described above, the operating unit 220 and the pedal 310 are connected via the support shaft.

By rotating the pedal 310 in the front-rear direction (e.g., G10, G12 direction) of the table 1, for example, the support shaft rotates in conjunction with the rotation, and the operation unit 220 coupled to the support shaft is operated. That is, by rotating the pedal 310, the lock mechanism 203 of the caster 202 can be operated, and the locked state and the unlocked state of the caster 202 can be switched.

Here, the end of the pedal 310 may have a protrusion 314 toward the inside of the table 1 (from the R side toward the L side). The protruding portion is preferably located above the base portion 20 (the housing portion 312), and thus the protruding portion of the pedal 310 is suppressed.

As shown in fig. 9, the pedal 310 may have a plate-like shape such as the pedal 315. The step 310 of fig. 8 is formed in a shape extending upward of the table 1, whereas the step 315 of fig. 9 is formed in a plate-like shape extending in the lateral direction (horizontal direction) of the table 1.

The pedal 310 of fig. 8 can switch the caster 202 to the locked state and the unlocked state by operating the end (upper end, protruding portion 314) of the pedal 310 by hand or by foot. In contrast, the pedal 315 of fig. 9 is formed in a shape suitable for the user to operate the pedal 315 so as to be able to kick down by foot.

2.2 pedal position

In the above embodiment, the pedal is disposed at a position along the outside of the base 20, but may be disposed, for example, on the upper side of the base 20.

For example, fig. 10 is a diagram showing a state in which the pedal 320 is held on the upper side of the base 20. The operation unit 220 is accommodated in the accommodation unit 322, and the pedal 320 is rotatably disposed above the accommodation unit 322. That is, the pedal 320 is provided above the foot of the table 1, and the pedal 320 can be prevented from protruding outward of the base 20. At this time, the pedal 320 is rotated in the front-rear direction (direction B, direction F) of the table 1, whereby the locked state and the unlocked state of the caster 202 can be switched.

2.3 shape of base (housing portion)

In order to prevent the pedal from protruding from the base 20, the shape of the base 20 (housing portion) may be changed. For example, the base 20 may have a shape having a notch so that the pedal enters the inside of the base 20.

For example, in fig. 11, the base 20 is formed in a shape recessed in the vicinity of the pedal 330 so as to enter the inside from the outer periphery of the base 20. In this case, the outer end (end in the R direction) of the step 330 is preferably located at a position along the extension of the base 20 or inside the extension. The base 20 is preferably formed in a shape cut into the inner side (L side) centering on the position of the pedal 330.

In this way, the amount of outward projection (for example, the amount of projection to the R side) of the pedal 330 can be suppressed as compared with the case where the outer peripheral portion of the base 20 is positioned on a straight line. In addition, by forming the front and rear sides of the pedal 330 in a concave shape, a space can be formed in the front and rear sides of the pedal 330. Since spaces are formed in the front and rear of the pedal 330, the pedal 330 is formed in a shape that facilitates the operation of stepping on the foot.

Fig. 12 is a view showing the housing 342 provided in the base 20 protruding outward from the base 20.

In fig. 12, the receiving portion 342 of the base 20 is formed to protrude outward (R direction). At this time, the portion of the housing 342 protruding along the virtual line P1 and the virtual line P2 is formed obliquely. Therefore, even if the foot of the user hits the base 20 (the receiving portion 342), the foot hits the protruding slope, and contact with the pedal 340 can be prevented.

[2.4 button-based operation ]

Fig. 13 shows an example of an operation unit including a button instead of a pedal as the operation mechanism 22. For example, as shown in fig. 13 (a), the base 20 has a button 352 and a button 354. For example, the user presses the button 352 to lock the caster 202. Further, for example, the user presses the button 354 to unlock the caster 202.

Here, as shown in fig. 13 (b), the lower ends of the buttons 352 and 354 are in contact with a pedal 356 incorporated in the base 20. Thus, for example, when the button 352 is pressed, one end side of the pedal 356 is pressed. In addition, when the button 354 is pressed, the other end side of the pedal 356 is pressed.

In this way, according to the structure of fig. 13, since the pedal 356 is not provided on the outside of the base 20, the protrusion of the operation portion can be eliminated. The user can switch the locking state and unlocking state of the caster by pressing the buttons 352 and 354. The user may press the buttons 352 and 354 by stepping on the buttons with his foot, or may press the buttons 352 and 354 by hand. Further, as shown in fig. 13 (a), by visually recognizing the state in which one button protrudes from the base 20, the user can easily confirm whether the caster 202 is in the locked state or the unlocked state. Here, the display buttons 352 and 354 may be recognized by different colors.

[2.5 protective Member ]

The base 20 may be provided with a protective member. For example, as shown in fig. 14, a rectangular shield member 410 may be provided so as to assist in the notch portion of the base 20. That is, the guard member 410 is disposed below the pedal 210. The position of the shield member 410 may be a position where the distal end portion of the pedal 210 abuts against the shield member 410 when the distal end portion is rotated.

[2.6 configuration of operating mechanism ]

In the above-described embodiment, the position of the operating mechanism is arranged along the width direction of the table 1 (for example, BF direction in fig. 1), but may be arranged at other positions. For example, the table 1 may be arranged along the longitudinal direction (for example, LR direction in fig. 1). In this case, the pedal 210 may be disposed on the F side, for example.

The operating mechanism 22 may be disposed in a direction inclined with respect to the base 20. For example, as shown in fig. 15, the operating mechanism 22 may be disposed near the corner of the base 20 in the shape of a letter コ. Specifically, the operation portion 220 is disposed in the corner portion in the oblique direction. Thus, the pedals 210 connected via the supporting shafts 212 are also arranged in the oblique direction. Thus, the pedal 210 can be configured not to protrude from the base 20. Further, since the pedal 210 is disposed obliquely, the pedal 210 can be disposed in a state in which the user can easily perform a depressing operation with his/her foot.

2.7 display of locked State/unlocked State

Regarding whether the state of the caster 202 is in the locked state or the unlocked state, it is described that the user can visually recognize according to the positions of the base 20 and the pedal 210, but it may be realized by another means. For example, a recognizable display (recognition display) may be provided on the pedal 210 and the operation unit (operation means). At this time, the identification of the locked state or the unlocked state is preferably performed on the upper surface of the base 20. For example, if the identification display is positioned on a plane perpendicular to the pedal axis, the identification display is performed on the side surface of the pedal 210, and the user's sight line is difficult to see. However, by performing the recognition display on the upper surface of the base 20, for example, even when the user who is operating looks at the table from above, it is possible to easily confirm whether the state of the caster 202 is the locked state or the unlocked state.

For example, fig. 16 is a diagram in which a recognition display is added to the pedal 330. The base 20 has a protruding portion for providing the pedal 330, and the protruding portion has a notch 420. A seal (seal) for identifying the locked state is attached to the pedal 330. For example, the orientation of the pedal 330 is changed by rotating the pedal 330. When the orientation of the pedal 330 is changed, the color that can be visually recognized through the notch 420 is changed. For example, stickers of different colors are attached to positions visually identifiable through the notch 420. The pedal 330 is added with different colors continuously, and the position of the color corresponding to the notch 420 is set in association with the rotation of the pedal 330. The notch 420 itself may be moved in conjunction with the rotation of the pedal 330. In this case, a notch 420 may be provided in the pedal 330, and a sticker for identifying a locked state may be attached to the base 20. In this case, the color of the sticker attached to the base portion 20 can be visually recognized from the notch 420 provided in the pedal 330. Thus, by rotating the pedal 330, the notch 420 rotates together, and the locked state can be visually recognized by the color of the sticker. The identified color may be, for example, a sticker of a different color or may be coated of a different color.

Specifically, in the case of the state of fig. 16 (a), a color (for example, fig. 16 (a) is indicated by a diagonal line, but is red, etc.) indicating the locked state is displayed in the notch 420. In the case of fig. 16 (b), a color (for example, fig. 16 (b) is shown by a screen, but is blue or the like) indicating the unlocked state is displayed in the notch 420.

In addition, a recognizable display unit may be provided on the base 20. For example, fig. 17 has a window 430 in the base 20. For example, the color of the sticker visible from the window portion 430 is changed in conjunction with the operation of the pedal 210. When the pedal 210 rotates, the orientation of the pedal 210 changes, and the pedal is interlocked with the fulcrum, cam, and slider. Then, the sticker or the like attached to the support shaft, the slider or the like is moved, and the locked state and the unlocked state of the caster 202 can be determined in accordance with the position of the support shaft or the cam. Therefore, a sticker having a different color is attached to the support shaft or the slider at a position where the support shaft or the slider is in the locked state or the unlocked state, or the coating is performed. Thus, the locked state or unlocked state of the caster 202 can be confirmed by the color displayed on the window 430.

Specifically, in the case of the state of fig. 17 (a), a color (for example, fig. 17 (a) is indicated by a diagonal line, but is red, etc.) indicating the locked state is displayed on the window 430. In the case of fig. 17 (b), a color (for example, fig. 17 (b) is shown by a screen, but is blue or the like) indicating the unlocked state is displayed on the window 430.

[2.8 Lock mechanism ]

In the above-described embodiment, the locking mechanism provided in the caster is described as an example of a mechanism for braking the movement of the table 1. However, any mechanism may be used as long as it is a mechanism for braking the movement of the table 1.

For example, a brake mechanism is attached to the wire 204. For example, the braking mechanism may be the following mechanism: a brake pad is provided, and when the wire 204 is pulled, the brake pad abuts against the floor surface, and acts to brake the movement of the table 1.

As a structure of the brake mechanism, for example, a brake mechanism disclosed in japanese patent application laid-open No. 2017-189312 (publication date: 10/19 of 2017, name of the invention: operating mechanism, and movable table provided with the operating mechanism) can be used. Other locking mechanisms and braking mechanisms may be used as long as they are mechanisms (braking mechanisms) for braking the movement of the table 1.

The locking mechanism and the braking mechanism may be combined. For example, a lock mechanism may be provided on the front side of the caster 202, and a brake mechanism may be provided on the rear side separately from the caster 202.

The above-described locking mechanism has been described as locking all casters, but casters necessary for preventing the table 1 from moving may be locked. For example, when four casters are provided at the base 20, three casters may be locked. The movement of the operating mechanism 22 to the locked position allows the casters to be locked as desired so that the table 1 cannot be moved freely.

[ application example ]

The above-described embodiment describes an example of applying the mobile device to the table 1 described below: the base 20 having the locking mechanism and the operating mechanism is used as a foot, and the column is one. The mobile device described above can of course be applied to other mobile devices.

Fig. 18 is a diagram of the application of the mobile device of the present embodiment to products other than the table 1. For example, fig. 18 (a) shows a table 3 for rehabilitation training. The table 3 of fig. 18 (a) has two (two side) legs, and the left and right sides of the table 3 have legs, respectively. The table having such a structure is similar to a rehabilitation table such as the table 3, for example, a table for a bed-crossing. In the case of such a table 3, the above-described embodiment can be applied by providing the base portion 20A in the shape of a letter コ at the foot portion. That is, the base 20A includes casters having a locking mechanism and an operating mechanism that operates the locking mechanism.

Further, as shown in fig. 18 (b), the table 5 having the end position holding means can also be realized in the same manner. That is, the legs are provided on the left and right sides of the table 5, but the above-described embodiment can be applied by providing the leg portion with the base portion 20B in the shape of a letter コ.

The above-described locking mechanism and operating mechanism are applied to a table as a moving device, but may be applied to other moving devices that can move with casters. For example, the present invention can be applied to furniture such as beds, stretchers, carts, cabinets, chairs, and lifting devices.
