The medication rack 11 of this embodiment does not need to have a plurality of casters 14. That is, the medication rack 11 may be a stationary rack that is not intended to be moved and is installed in a facility.

[0024] In this embodiment, one or more storage sections 13 are formed in a pair, but the number of storage sections 13 is arbitrary and may be one, or may be three or more. The first handle 16 is installed at a different installation height from the second handle 17, for example. Some of the multiple casters 14 may have built-in brakes that can lock the rollers.

[0025] The pair of side walls 23 and the rails 24 are integrally molded, for example, from a synthetic resin material. The rails 24 are installed in the storage section 13 in a number greater than the number of the trays 15. The rails 24 are formed on the pair of side walls 23 so as to be provided in one or more storage sections 13. The rails 24 can guide the flanges 44 so that the trays 24 move forward and backward between the storage position P1 and the pull-out position P2. As shown in Figs. 3 and 4, each of the rails 24 has a recess 27 into which the flanges 44 (described later) of the trays 15 in the storage position P1 can be depressed, and a pair of locking claws 28 that protrude upward to define both ends of the recess 27 in the front-rear direction D1. The rails 24 can guide the flanges 44 so that the trays 24 move forward and backward between the storage position P1 and the pull-out position P2.

[0026] 3 to 5, the multiple through holes 25 allow the multiple engagement portions 18 to protrude into the storage portion 13. As described below, the multiple engagement portions 18 can protrude into the storage portion 13 via the multiple through holes 25, or can retreat from the storage portion 13 by being embedded in the multiple through holes 25.

[0027] 1 and 3, the rack body 12 has a bottom plate portion 31, a frame 32 formed on the bottom plate portion 31 by framing metal bars in a square box shape, a top plate portion 33 fitted to the upper part of the frame 32, a pair of side plate portions 34 fitted to the sides of the frame 32, a back plate portion 35 fitted to the back part of the frame 32, and a frame portion 36 surrounding the opening 13A of one or more storage portions 13. The pair of side walls 23 are fixed to the frame 32. In this embodiment, the top plate portion 33, the pair of side plate portions 34, and the back plate portion 35 are preferably formed of a non-translucent metal plate or the like, for example, in consideration of the privacy of facility users.

[0028] In this embodiment, the frame portion 36 has an upper horizontal frame portion 36A that is provided directly below the upper front of the frame 32 and defines the upper edge of the opening 13A. In this embodiment, the frame portion 36 does not have a lower horizontal frame portion that defines the lower edge of the opening 13A and a pair of vertical frame portions that define the right and left edges of the opening 13A. The pair of vertical frame portions of the frame portion 36 are substituted by the front portions of both the left and right ends of the frame 32. The lower horizontal frame portion of the frame portion 36 is substituted by the bottom plate portion 31. The frame portion 36 may have the lower horizontal frame portion and the pair of vertical frame portions.

[0029] As shown in FIG. 2, the operation unit 22 is provided on an upper horizontal frame portion 36A of the frame portion 36. The upper horizontal frame portion 36A has a display portion 37. The display portion 37 can display a "closed" state in which the multiple engagement portions 18 are in an engagement position S1 where they are engaged with the multiple trays 15, and an "open" state in which the multiple engagement portions 18 are in a separation position S2 where they are separated from the multiple trays 15. The display portion 37 is configured with a window formed by a through hole or the like. As shown in FIG. 2 and FIG. 13, the display portion 37 can display a closed marker 41 indicating the closed state and an open marker 42 indicating the open state within the window.

[0030] The plurality of trays 15 are configured to be movable between a storage position P1 where the trays are stored in the storage section 13 and a pull-out position P2 where the trays are pulled out from the storage section 13. The plurality of trays 15 can be installed on any one of the plurality of rails 24. As shown in FIG. 12, the plurality of trays 15 include one or more first trays 15A and one or more second trays 15B different in size from the first tray 15A. As shown in FIGS. 7 and 8, the first tray 15A has a box-shaped tray body 43 with an open top and a pair of flanges 44 that protrude from the side of the tray body 43 in a plate-like shape toward the side. The first tray 15A is integrally molded, for example, from a synthetic resin material. Various plates 46 (plates bearing information such as room numbers) can be attached to a plate attachment portion 45 provided in the front of the tray body 43. 9, for example, a plurality of individual medication cases 47 for individually storing medicines can be stored inside first tray 15A, and paper documents such as prescriptions can be stored above the plurality of individual medication cases 47. Flange 44 has protrusion 44A protruding downward on the lower surface of the rear part thereof.

[0031] As shown in Figs. 10 and 11, the second tray 15B has a box-shaped tray body 43 with an open top, a pair of flanges 44 that protrude from the side of the tray body 43 in a plate-like shape toward the side, and a cover plate 48 that protrudes upward from the front of the tray body 43 in a flat plate shape. The second tray 15B is integrally molded from, for example, a synthetic resin material. Various plates 46 (plates with information such as room numbers) can be attached to a plate mounting portion 45 provided at the front of the tray body 43. The cover plate 48 is provided to cover the contents of the second tray 15B from the surroundings so that they cannot be seen from the front. As shown in Figs. 10 to 12, the second tray 15B includes multiple types of trays with different height dimensions of the cover plate 48. The inside of the second tray 15B can store not only the multiple individual medication cases 47 described above, but also, for example, bottles of medicinal liquids and large paper files.

[0032] The first tray 15A and the second tray 15B, which are different in size from each other, can be fixed to the rack body 12 in a random combination as shown in Fig. 12. In this case, medical personnel and care personnel (hereinafter simply referred to as personnel) can attach the first tray 15A to any location in the storage section 13 of the rack body 12, and can attach the second tray 15B to any location in the storage section 13 of the rack body 12. As shown in Figs. 12 and 16, the multiple trays 15 (first tray 15A, second tray 15B) can advance and retreat between a storage position P1 where they are stored in the storage section 13 and a pull-out position P2 where they are pulled out from the storage section 13.

[0033] As shown in Fig. 2, the operating unit 22 is provided on the upper horizontal frame portion 36A. The operating unit 22 has a locking mechanism 51 that operates the switching mechanism 21, and a key 52 that is inserted into the locking mechanism 51. As shown in Figs. 5 and 6, the locking mechanism 51 has a cylinder portion 54 having a keyhole 53, and a pin 55 that is connected to the cylinder portion 54 and rotates as the cylinder portion 54 rotates. A user can rotate the cylinder portion 54 and the pin 55 connected thereto by inserting the key 52 into the keyhole 53 and rotating it.

[0034] As shown in FIG. 2, the pair of protective members 26 are provided so as to protrude forward from the upper horizontal frame portion 36A in a mountain shape. The pair of protective members 26 are made of, for example, a synthetic resin material, but may be made of a rubber material. The height at which the pair of protective members 26 protrude from the upper horizontal frame portion 36A is preferably approximately the same as or higher than the height of the key 52 inserted into the locking mechanism 51. The pair of protective members 26 can protect the locking mechanism 51 into which the key 52 is inserted, and can protect the key 52 and the locking mechanism 51 from being damaged when a user of a medical facility or a care facility (hereinafter simply referred to as a user) accidentally touches the key 52, while at the same time protecting the user's fingers and the like.

[0035] 5 and 6, the switching mechanism 21 has a link member 56 that is connected to a pin 55 of the lock mechanism 51 of the operation unit 22 and extends in the horizontal direction, and a rod member 57 that extends in the vertical direction and is connected to the link member 56. That is, the rod member 57 extends in a direction intersecting (perpendicular to) the link member 56. As shown in FIGS. 3 and 6, the rod member 57 is passed through a vertical hole 23A formed on the back surface of the side wall 23 and is held rotatably.

[0036] As shown in FIG. 5 and FIG. 6, the link member 56 is attached to the link rail 58 fixed to the upper horizontal frame portion 36A via a roller 61. The link member 56 can move forward and backward along the longitudinal direction of the link rail 58. The link member 56 has an elongated plate-like link member main body 56A, a pair of claws 56B protruding upward from the middle part of the link member main body 56A in a flat plate shape, and arm parts 56C protruding laterally in a plate shape from both ends of the link member main body 56A. One of the pair of claws 56B has a close marker 41 (close label) indicating that the engagement parts 18 are in an engagement position S1 where they are engaged with the trays 15. The other of the pair of claws 56B has an open marker 42 (open label) indicating that the engagement parts 18 are in a separation position S2 where they are separated from the trays 15.

[0037] The pin 55 of the lock mechanism 51 has its tip held between a pair of claw portions 56B of the link member 56. The arm portion 56C has an elongated hole 62. The elongated hole 62 can hold a crank pin 57B (described later) of the rod member 57 by passing it through the inside.

[0038] The rod member 57 has a shaft portion 57A extending in the vertical direction, and a crank pin 57B provided at an end (upper end) of the shaft portion 57A. The multiple engagement portions 18 are fixed discretely in the axial direction of the shaft portion 57A. It is preferable that the multiple engagement portions 18 are fixed at regular intervals to the shaft portion 57A.

[0039] Each of the engagement parts 18 is formed of a semicircular piece-like piece and is fixed so as to be wound around the shaft part 57A of the rod member 57. Therefore, the engagement parts 18 project into the storage part 13 and engage with the trays 15 as the rod member 57 rotates around the shaft in one direction, and are set to an engagement position S1 where the trays 15 are prevented from moving to the pull-out position P2. The engagement parts 18 retract from the storage part 13 and are set to a separation position S2 separated from the trays 15 as the rod member 57 rotates around the shaft in the opposite direction to the one direction. When the engagement parts 18 are in the engagement position S1, they project into the storage part 13 through the through holes 25 (see Figs. 3 and 4). In the state of being in this engagement position S1, the engagement parts 18 are positioned on the opposite side of the rails 24 with the flange parts 44 of the trays 15 sandwiched therebetween. Therefore, when the multiple engagement portions 18 are in the engagement position S1, the multiple flange portions 44 can be held within the multiple recesses 27 of the multiple rails 24.

[0040] In this state of being in the engagement position S1, the multiple engagement parts 18 may abut against the flange part 44, or may face the flange part 44 with a slight clearance. Considering the variation in the positions of the multiple engagement parts 18 when assembled, the variation in the position of the rail 24, the variation in the thickness of the flange part 44, etc., it is preferable that the multiple engagement parts 18 face the flange part 44 with a slight clearance. This also prevents the multiple trays 15 from being erroneously drawn from the storage position P1 to the drawing position P2, since the flange part 44 is held in the recess 27 of the rail 24. In addition, by facing the multiple engagement parts 18 with a slight clearance from the flange part 44, no frictional force is generated between the multiple engagement parts 18 and the flange part 44 when the multiple engagement parts 18 rotate, and the force required for the relevant person to switch the multiple trays 15 between the locked state and the unlocked state can be reduced.

[0041] Next, the operation of the medication rack 11 of this embodiment will be described with reference to FIGS. 2 to 6 and 12 to 16.

[0042] In the state shown in FIG. 12, each of the multiple trays 15 is arranged at a storage position P1 stored in the storage section 13. As shown in FIG. 3 and FIG. 4, each of the multiple trays 15 is in a locked state in which it is engaged by the multiple engagement parts 18 and is prohibited from moving to the pull-out position P2. At this time, the multiple engagement parts 18 are in the engagement position S1. In this state, security is ensured for the medication rack 11, and the medication rack 11 is usually installed in a medical facility or a nursing facility in such a state of security. Therefore, even if a third party who is not a related party comes into contact with this medication rack 11, the individual trays 15 cannot be moved to the pull-out position P2 to access the medicines inside. In addition, in such a state of security, as shown in FIG. 2, the close marker 41 can be seen through the window of the display unit 37.

[0043] Typically, in a medical facility or a care facility, one tray 15 (first tray 15A, second tray 15B) is prepared for one user. For example, a plate 46 bearing only a room number or the like is attached to the plate attachment portion 45 of the tray 15 in consideration of the user's privacy. A plurality of individual medication cases 47 are placed in the tray 15, and one dose of medication for the user is stored in each individual medication case 47. Therefore, in the entire tray 15, a week's worth or more of medication is stored in an easy-to-understand state organized by the time of administration, for example, after breakfast, after lunch, after dinner, before bedtime, etc.

[0044] When a person concerned wishes to access the medicines in the tray 15, he or she inserts the key 52 into the keyhole 53 of the lock mechanism 51 in the upper horizontal frame portion 36A of the medicine dispensing rack 11 shown in Fig. 12 as shown in Fig. 2, and rotates it a predetermined angle to the state shown in Fig. 13. This makes the open marker 42 visible through the window of the display unit 37.

[0045] At the same time, as shown in Figs. 5, 6, 14, and 15, the pin 55 of the lock mechanism 51 rotates around the cylinder portion 54. Accordingly, the link member 56 with the pin 55 inserted between the pair of claw portions 56B also moves along the link rail 58. As the link member 56 moves, the arms 56C at both ends of the link member 56 move the crank pin 57B of the rod member 57, causing the rod member 57 to rotate around the shaft portion 57A. Due to this rotation (rotation) of the rod member 57, the multiple engagement portions 18 in the shape of a frame wound around the rod member 57 rotate and move from the engagement position S1 to the separation position S2. At this time, the multiple engagement portions 18 go from a state in which the tips of the multiple engagement portions 18 penetrate the multiple through holes 25 and protrude into the storage portion 13 to a state in which the multiple engagement portions 18 are recessed into the multiple through holes 25 and retreat from the storage portion 13. As a result, the state in which the multiple engagement portions 18 are engaged with the multiple trays 15 is released, and the locked state of the multiple trays 15 is released.

[0046] With the lock released in this manner, the person in charge can pull out the multiple trays 15 individually or simultaneously from the storage position P1 to the pull-out position P2 and pick up the medicines for the intended user.

[0047] At that time, as shown in Fig. 16, when the tray 15 is pulled out to the frontmost position with the tray 15 in the pulled-out position P2, the tray 15 (first tray 15A, second tray 15B) is held in a forward tilted position P3 with the front part tilted downward. At this time, the protrusion 44A protruding downward from the rear end of the lower surface of the flange 44 is locked with the locking claw 28 at the front end of the rail 24, and the rear end upper surface 44B of the flange 44 abuts against the lower surface of another rail 24 directly above the rail 24. This maintains the forward tilted position P3 of the tray 15. In this forward tilted position P3, it is easy for related persons to see the inside of the tray 15.

[0048] To return the multiple trays 15 to the locked state again, the multiple trays 15 are returned to the horizontal state, moved from the drawn-out position P2 to the stored position P1, the key 52 is rotated so as to return to the angle before rotation, and the multiple engagement parts 18 are moved to the engagement position. Then, by removing the key 52 from the locking mechanism 51, the locking state can be easily returned to one in which security is ensured.

[0049] According to the first embodiment, the following can be said. The medication rack 11 includes a rack body 12 having a storage section 13 and a frame section 36 surrounding an opening 13A of the storage section 13, a plurality of trays 15 stored in the storage section 13, the plurality of trays 15 being movable between a storage position P1 stored in the storage section 13 and a pull-out position P2 pulled out from the storage section 13, a plurality of engagement sections 18 movable between an engagement position S1 that engages with the plurality of trays 15 to prohibit the movement of the plurality of trays 15 to the pull-out position P2 and a separation position S2 that is separated from the plurality of trays 15, a switching mechanism 21 that can collectively switch between a state in which the plurality of engagement sections 18 are in the engagement position S1 and a state in which the plurality of engagement sections 18 are in the separation position S2, and an operation section 22 provided in the frame section 36 for operating the switching mechanism 21.

[0050] According to this configuration, the operating unit 22 and the switching mechanism 21 can switch the multiple engagement parts 18 between the engagement position S1 and the separation position S2 in a lump. This allows the relevant person to easily remove the user's medicine from the medication rack 11 by operating the operating unit 22. In addition, since the multiple trays 15 can be switched between the locked state and the unlocked state in a lump, the workability can be improved and the work burden on the relevant person can be reduced compared to the case where the lock is released for each tray 15. In addition, since only the relevant person can release the locked state of the trays 15 in this way, even if a method of locking and unlocking in a lump is adopted, there is no problem in terms of security. In addition, by locking in a lump, the structure can be simplified and costs can be reduced compared to a structure in which the locked state and the unlocked state can be set individually for each tray 15. Furthermore, a shutter or the like provided at the opening 13A for locking the multiple trays 15 is not necessary, and a low-cost medication rack 11 that is not easily broken can be realized.

[0051] In this case, the switching mechanism 21 has a link member 56 that is connected to the operating unit 22 and moves back and forth in response to operation of the operating unit 22, and a rod member 57 that rotates about an axis in response to the forward and backward movement of the link member 56, and has a plurality of engagement portions 18 discretely fixed in the axial direction of the rod member 57, and the plurality of engagement portions 18 protrude into the storage unit 13 to an engagement position S1 as the rod member 57 rotates in one direction about the axis, and retracted from the storage unit 13 to a separated position S2 as the rod member 57 rotates in the opposite direction to the one direction.

[0052] According to this configuration, a structure can be realized in which multiple trays 15 can be switched between a locked state and an unlocked state collectively with a simple structure using link member 56 and rod member 57. In addition, since the rotation around the axis of rod member 57 is utilized, the frictional force acting between each member can be reduced, and the amount of force required to move multiple engagement parts 18 between engagement position S1 and separation position S2 can be reduced, compared to a method in which multiple engagement parts 18 are slid (raised) using a cam or the like. This makes it possible to realize a medication rack 11 that reduces the workload of related personnel.

[0053] In this case, there are a plurality of flange portions 44 protruding from the respective tray bodies 43 of the plurality of trays 15, and a plurality of rails 24 provided in the storage section 13, each of which has a recess 27 into which the flange portions 44 fall when the plurality of trays 15 are in the storage position P1, and which guide the flange portions 44 so that the plurality of trays 15 move forward and backward between the storage position P1 and the pull-out position P2. When in the engagement position S1, the plurality of engagement portions 18 are positioned on the opposite side of the plurality of rails 24 with the plurality of flange portions 44 in between, and hold the plurality of flange portions 44 within the front plurality of recesses 27.

[0054] According to this configuration, the structure in which the flange 44 is sandwiched between the rails 24 and the engagement parts 18 and held in the recess 27 allows the multiple trays 15 to be stably held in the storage position P1. Also, by ensuring a slight clearance (gap) between the multiple engagement parts 18 and the flange 44 without abutting the multiple engagement parts 18 against the flange 44, it is possible to prevent friction from occurring between them and reduce the amount of force required for the relevant person to switch the tray 15 between the locked state and the unlocked state. This reduces the workload of the relevant person.

[0055] The rails 24 are installed in the storage unit 13 in a number greater than the number of the trays 15, and the trays 15 can be installed on any one of the rails 24. This configuration makes it possible to realize a medication rack 11 that is easy to use for related personnel.

[0056] The multiple trays 15 include one or more first trays 15A and one or more second trays 15B that are different in size from the first trays 15A. With this configuration, various medicines can be stored in each tray 15. For example, in the smaller trays 15, a single dose of medicine to be administered to a user can be divided into small portions and stored in an organized state. In the larger trays, for example, bottles containing liquid medicine can be stored. In this way, by being able to store various medicines, the freedom of use of the relevant personnel can be improved, and a medicine-dispensing rack 11 that is easy for the relevant personnel to use can be realized.

[0057] One or more second trays 15B have a tray body 43 and a blind plate portion 48 protruding upward from the front of the tray body 43. With this configuration, the medicines stored in the tray 15 can be made invisible from the outside, and a medicine-dispensing rack 11 that also takes into consideration the privacy of the user can be realized.

[0058] The frame 36 has an upper horizontal frame 36A, and the operation unit 22 is provided on the upper horizontal frame 36A. With this configuration, the operation unit 22 is arranged in a position where it is easy for the relevant personnel to work, thereby reducing the workload of the relevant personnel. In addition, the operation unit 22 being located in a position where it is difficult to operate can be prevented from occurring in which multiple trays 15 are not locked. In addition, the operation unit 22 can be arranged in a position where it is easily visible to the relevant personnel. This can prevent the medication rack 11 from being forgotten to be locked, etc. These can improve the security of the medication rack 11.

[0059] The operating unit 22 has a lock mechanism 51 that operates the switching mechanism 21, and a key 52 that is inserted into the lock mechanism 51 to rotate the lock mechanism 51. According to this configuration, by employing the key 52 and the lock mechanism 51, the people who can operate the operating unit 22 can be limited to related parties. This improves the security of the medication rack 11.

[0060] The upper horizontal frame portion 36A has a display portion 37, which indicates whether the multiple engagement portions 18 are in the engagement position S1 or the separation position S2. This configuration allows relevant personnel to check at a glance whether the medication rack 11 is locked or unlocked.

[0061] The medication rack 11 has a pair of protective members 26 provided to protrude from the upper horizontal frame portion 36A at positions on both sides of the operating unit 22. With this configuration, if a person nearby accidentally touches the locking mechanism 51 of the operating unit 22 and the key 52 inserted therein, the contact part of the person is protected and at the same time, the contacted locking mechanism 51 and key 52 can be prevented from being damaged.

[0062] In the following embodiment, differences from the first embodiment will be mainly described, and illustrations or descriptions of parts common to the first embodiment will be omitted. [Second embodiment]

[0063] A second embodiment of the medication rack 11 will be described with reference to Figs.

[0064] The operating unit 22 is configured with a lever mechanism 71 that is operated by the fingers of a person involved, thereby operating the switching mechanism 21. The lever mechanism 71 has a central axis 72, a cylindrical cylinder member 73 that is rotatable around the central axis 72, a finger hook member 74 that protrudes outward from the outer periphery of the cylinder member 73, and a pin 55 that protrudes downward from the outer edge of the lower surface of the cylinder member 73 and rotates with the rotation of the cylinder member 73. The finger hook member 74 is formed in a knob shape on which a person involved can hook their fingers. The tip of the pin 55 is held between a pair of claws 56B of the link member 56.

[0065] The cylinder member 73 has an indicator 37 on its outer circumferential surface. The indicator 37 has an open marker 42 (open label) indicating that the trays 15 are in an unlocked state (the engagement parts 18 are in the engagement position S1), and a closed marker 41 (closed label) indicating that the trays 15 are in a locked state (the engagement parts 18 are in the separation position S2). The open marker 42 and the closed marker 41 are provided on both sides of the finger hook member 74. As shown in FIG. 21, the open marker 42 is disposed on the right side of the finger hook member 74 when viewed from the front. As shown in FIG. 20, the closed marker 41 is disposed on the left side of the finger hook member 74 when viewed from the front. The open marker 42 is, for example, a red label, but may be a label with the character "open". The closed marker 41 is, for example, a blue label, but may be a label with the character "close".

[0066] In this embodiment, the medication rack 11 has a key-type lock mechanism 75 that prohibits rotation of the operation unit 22 (lever mechanism 71). As shown in Figures 18 and 19, the lock mechanism 75 includes a lock unit 76, a key (not shown) that is inserted into the lock unit 76, and a stopper unit 77 with an "L"-shaped cross section attached to the rotatable cylinder unit 54 of the lock unit 76.

[0067] In this embodiment, the link member 56 has a hook portion 56D that can engage with the stopper portion 77. Therefore, when the hook portion 56D is engaged with the stopper portion 77, the link member 56 is prohibited from moving back and forth along the longitudinal direction of the link rail 58.

[0068] The pair of protective members 26 are provided so as to protrude forward from the upper horizontal frame portion 36A in a mountain shape. The pair of protective members 26 are made of, for example, a synthetic resin material, but may be made of a rubber material. It is preferable that the height at which the pair of protective members 26 protrude from the upper horizontal frame portion 36A is approximately the same as or higher than the height of the finger hook member 74 of the lever mechanism 71. The pair of protective members 26 can protect the finger hook member 74, and can protect the finger hook member 74 from damage when the user accidentally touches the key, and at the same time, can prevent the user from being injured.

[0069] In this embodiment, a lock mechanism 75 that prevents the lever mechanism 71 from rotating is provided, and the lock mechanism 75 is also preferably provided between the pair of protective members 26. In this way, when the key 52 is inserted into the locking portion 76 of the lock mechanism 75, the pair of protective members 26 can protect the lock mechanism 75 from damage and at the same time prevent the user from being injured.

[0070] Next, the operation of the medication rack 11 of this embodiment will be described with reference to Figs.

[0071] In the state shown in FIG. 17, each of the multiple trays 15 is arranged at a storage position P1 stored in the storage section 13. As shown in FIG. 19, each of the multiple trays 15 is in a locked state in which it is prohibited from moving to the pull-out position P2 by being engaged by the multiple engagement parts 18. In addition, since the movement of the link member 56 of the switching mechanism 21 is prohibited by the lock mechanism 75, the lever mechanism 71 of the operation part 22 cannot be operated by a person other than the person concerned. In this state, security is ensured for the medication rack 11, and the medication rack 11 is usually installed in a medical facility or a care facility in such a state of security. Therefore, even if a third party who is not a related person comes into contact with this medication rack 11, the individual trays 15 cannot be moved to the pull-out position P2 to access the medicines inside. In addition, in such a state in which security is ensured, the close marker 41 provided on the cylinder member 73 can be seen as shown in FIG. 20.

[0072] When a staff member wishes to access the medicines in the tray 15, he or she inserts a key into the lock portion 76 of the lock mechanism 75 of the medication rack 11 shown in Figure 18. This causes the cylinder member 73 and the stopper portion 77 connected thereto to rotate in the direction of the arrow, as shown in Figure 19. This releases the link member 56 from the stopper portion 77. This allows the staff member to operate the operating portion 22 (lever mechanism 71).

[0073] When the relevant person rotates the lever mechanism 71 from the position shown in FIG. 20 to the position shown in FIG. 21, the cylinder member 73 and the pin 55 rotate as shown in FIG. 19, and the link member 56 moves along the link rail 58. As the link member 56 moves, the arm 56C of the link member 56 moves the crank pin 57B of the rod member 57, and the rod member 57 rotates around the shaft 57A. This rotation (rotation) of the rod member 57 causes the multiple engagement parts 18 in the shape of a frame wound around the rod member 57 to turn and move from the engagement position S1 to the separation position S2. At this time, the multiple engagement parts 18 go from a state in which they penetrate the multiple through holes 25 and their tips protrude into the storage section 13 to a state in which they are retracted from the storage section 13 by being buried in the multiple through holes 25. This releases the state in which the multiple engagement parts 18 engage with the multiple trays 15, and the locked state of the multiple trays 15 is released.

[0074] With the lock released in this manner, the person in charge can pull out the multiple trays 15 individually or simultaneously from the storage position P1 to the pull-out position P2 and pick up the medicines for the intended user.

[0075] When in the pulled-out position P2, the trays 15 (first tray 15A, second tray 15B) can also be held in a forward tilted position P3 in which the front parts of the trays 15 (first tray 15A, second tray 15B) are tilted downward as shown in Fig. 16. At this time, a protrusion 44A protruding downward from the rear end of the lower surface of the flange 44 is engaged with a locking claw 28 at the front end of the rail 24, and a rear end upper surface 44B of the flange 44 abuts against the lower surface of another rail 24 directly above the rail 24. This holds the trays 15 in the forward tilted position P3. In this forward tilted position P3, it is easier for related parties to see the inside of the trays 15.

[0076] When returning the multiple trays 15 to the locked state, the multiple trays 15 are returned to the horizontal state and moved from the drawn-out position P2 to the stored position P1, the lever mechanism 71 is rotated to return to the angle before rotation, and the multiple engagement portions 18 are moved to the engagement position S1. Then, the key is rotated to the original angle, and the stopper portion 77 rotates and engages with the hook portion 56D of the link member 56. This prohibits the rotation of the lever mechanism 71. By removing the key from the lock portion 76 in this state, the lock state can be easily returned to one in which security is ensured.

[0077] According to this embodiment, the following can be said. The operating unit 22 is a lever mechanism 71 that is rotated by a finger to operate the switching mechanism 21. With this configuration, the relevant personnel can easily switch between the locked state and the unlocked state of the multiple trays 15. This reduces the workload of the relevant personnel and realizes a medication rack 11 that is easy to use.

[0078] The medication rack 11 has a key-type locking mechanism 75 that prohibits rotation of the lever mechanism 71. This configuration makes it possible to prevent the operation unit 22, which is made up of the lever mechanism 71, from being operated by anyone other than the relevant personnel. This makes it possible to realize a medication rack 11 that takes into consideration both operability and security.

[0079] The lever mechanism 71 has an indicator 37 that indicates whether the multiple engagement parts 18 are in the engagement position S1 or the separation position S2. With this configuration, the relevant person can check at a glance whether the medication rack 11 is in the locked or unlocked state. [Third embodiment]

[0080] A third embodiment of the medication rack 11 will be described with reference to Figures 22 and 23. In this embodiment, the shape of the first tray 15A and the second tray 15B of the multiple trays 15 and the positions at which the multiple engagement portions 18 engage with the multiple trays 15 are different from those of the first embodiment. In this embodiment, the number of the multiple trays 15 and the number of rails 24 are configured to be the same.

[0081] 22, in this embodiment, the multiple trays 15 (first tray 15A and second tray 15B) do not have a flange portion 44. In the recess 27 of the rail 24, a tray main body 43, not the flange portion 44, is held.

[0082] When in the engagement position S1, the multiple engagement portions 18 are positioned on the opposite side of the multiple rails 24 with the multiple tray bodies 43 interposed therebetween. When in the engagement position S1, the multiple engagement portions 18 hold the multiple tray bodies 43 in the multiple recesses 27.

[0083] The first tray 15A has an upper edge 43A of the tray body 43. In this embodiment, as shown in FIG. 23, in the state of this engagement position S1, the multiple engagement parts 18 may abut against the upper edge 43A, or may face the upper edge 43A with a slight clearance. Considering the variation in the positions of the multiple engagement parts 18 when assembled, the variation in the position of the rail 24, the variation in the position of the upper edge 43A, etc., it is preferable that the multiple engagement parts 18 face the upper edge 43A with a slight clearance. This also prevents the multiple trays 15 from being erroneously drawn out from the storage position P1 to the drawing position P2, since the tray body 43 is held in the recess 27 of the rail 24. In addition, since the multiple engagement portions 18 face the upper edge 43A with a slight clearance therebetween, no frictional force acts between the multiple engagement portions 18 and the upper edge 43A when the multiple engagement portions 18 rotate, reducing the amount of force required by a person involved to switch the multiple trays 15 between the locked and unlocked states.

[0084] According to this embodiment, the following can be said: The medication rack 11 includes a tray body 43 provided on each of the multiple trays 15, and multiple rails 24 provided in the storage section 13, each of which has a recess 27 into which the tray body 43 falls when the multiple trays 15 are in the storage position P1, and the multiple rails 24 guide the tray body 43 so that the multiple trays 15 move forward and backward between the storage position P1 and the pull-out position P2, and the multiple engagement sections 18 are positioned on the opposite side of the multiple rails 24 with the multiple tray bodies 43 in between when in the engagement position S1, and hold the multiple tray bodies 43 within the multiple recesses 27.

[0085] According to this configuration, the structure in which the tray body 43 is sandwiched between the rails 24 and the engagement parts 18 and held in the recess 27 allows the multiple trays 15 to be stably held in the storage position P1. Also, by ensuring a slight clearance (gap) between the multiple engagement parts 18 and the tray body 43 without abutting the multiple engagement parts 18 against the tray body 43, it is possible to prevent friction from occurring between them and reduce the amount of force required for a person involved to switch the tray 15 between the locked state and the unlocked state. This reduces the workload of the person involved.

[0086] The above-described embodiment can be implemented with various substitutions and modifications. In addition, the above-described embodiments can be naturally combined appropriately to realize the invention. [Explanation of symbols]
