  Hereinafter, a nurse call slave device according to an embodiment of the present invention will be described in detail with reference to the drawings.

First, the overall configuration of the nurse call system 1 will be briefly described with reference to FIG. FIG. 1 is a system explanatory diagram showing the overall configuration of the nurse call system 1.
The nurse call system 1 is installed in the vicinity of each bed in a hospital room, and is installed in the vicinity of nurse call handsets 2, 2,. Corridor lamps 3, 3, etc. for notifying the operation of the call handset 2 by flashing, etc., and a nurse call parent for answering calls from the nurse call handset 2, 2. Machine 4 and a controller 5 for controlling the call operation and the like of these devices. The nurse call slave units 2, 2,..., The corridor lamps 3, 3, .., the nurse call master unit 4, and the control unit 5 are electrically connected via a line L. Each nurse call slave unit 2 includes a plate slave unit 11 installed on an installation surface W such as a wall surface, and a hand slave unit 12 including a button unit 12a that can be operated by a patient. The machines 11 and 12 are connected by connectors as will be described later.

Here, a structure for connector-connecting the plate slave unit 11 and the hand slave unit 12 in the nurse call slave unit 2, which is a main part of the present invention, will be described with reference to FIGS.
FIG. 2 is an explanatory view showing the plate slave unit 11 from the front, and FIG. 3 is an explanatory view showing the plate slave unit 11 from the side. FIG. 4 is an explanatory view showing the plate slave unit 11 with the decorative panel 13 removed from the front, and FIG. 5 is an explanatory view showing a cross section taken along line AA in FIG. FIG. 6 is an explanatory perspective view of the plate slave unit 11 in an exploded state. FIG. 7 is an explanatory view showing the plate slave unit 11 with the hook 27 in the standing posture from the front, and FIG. 8 is an explanatory diagram showing the plate slave unit 11 with the hook 27 in the standing posture from the side. . FIG. 9 is an explanatory view showing a cross section of the plate slave unit 11 in a state where the plate side connector 20 and the hand side connector 35 are connected.

  First, the structure of the plate slave unit 11 will be described. The plate slave unit 11 includes a main body case including a storage box 14 embedded in the installation surface W, and a lid 15 assembled on the front side of the storage box 14; And a decorative panel 13 which is assembled so as to cover the peripheral edge of the lid 15. The storage box 14 is a synthetic resin box having an opening on the front surface, and a main body substrate 17 for outputting various signals to the hallway lamp 3 is provided on the rear side of the storage box 14, and the front side thereof is provided on itself. A switch board 19 mounted with a switch that is turned ON / OFF by pressing the provided button 18 is incorporated. In addition, a plate-side connector 20 for connecting the hand-side connector 35 of the hand slave unit 12 is built in the storage box 14. The plate-side connector 20 is a so-called male connector having one pin 20a, and is attached in such a posture that the pin 20a faces downward with an inclination angle of 24 ° with respect to the installation surface W. A part of the base end side of the plate-side connector 20 is located in a space sandwiched between the main body substrate 17 and the switch substrate 19 in the front-rear direction. Reference numeral 21 denotes a holding frame for attaching the plate side connector 20 or installing the switch board 19, and is fixed in the storage box 14. The holding frame 21 is provided with a guide surface 21 a for guiding the hand side connector 35 inserted into the storage box 14 to the plate side connector 20. Furthermore, 22 is a screwing plate for installing the plate slave unit 11 on the wall surface, and can be attached to a flange portion 23 provided at the front opening edge of the storage box 14.

  On the other hand, the lid 15 is a plate-like member that is assembled so as to cover the front opening of the storage box 14, and has an insertion hole 24 for inserting the hand-side connector 35 into the storage box 14 from the center to the bottom. ing. In addition, a button plate 25 is provided on the top of the lid 15, and a button 18 for stopping the blinking of the corridor lamp 3 by a pushing operation is attached so as to contact the button plate 25. Further, a bearing portion 26 is provided between the insertion hole 24 and the button plate 25, and a hook 27 for hooking the hand slave unit 12 is provided on the bearing portion 26 so as to be rotatable about the left and right direction. It has been.

  The hook 27 is formed in a substantially L shape in a side view, and has a tongue piece portion 28 extending in the vertical direction, and a curved piece portion 29 that protrudes forward from the lower end portion of the tongue piece portion 28 and is bent upward. And a shaft portion 30 at the upper end, and a frame portion 31 provided integrally with the tongue piece portion 28 around the tongue piece portion 28. The hook 27 is tilted so that the rear surface of the hook 27 comes into contact with the front surface of the lid 15 as shown in FIGS. 2 and 3, and the rear surface of the hook 27 with respect to the lid 15 as shown in FIGS. It is possible to turn between the standing postures of approximately 90 °. Further, when the hook 27 is in a tilted posture, the tongue piece portion 28 covers the front of the insertion hole 24 in front view. However, the tongue piece 28 has a bulging shape that bulges forward in an arc shape, and is formed such that the amount of bulging forward increases gradually as it goes downward, and the hook 27 is tilted. The cable 36 of the hand side connector 35 inserted into the insertion hole 24 is allowed to pass between the rear surface of the tongue portion 28 of the hook 27 and the front surface of the lid 15, and the cable 36 is hooked. A space 32 for escaping to the outside of 27 is formed. Note that the center of gravity of the hook 27 is in a position such that when the wall surface is installed as the installation surface W, the hook 27 is automatically tilted. Also, in the case where a projecting portion that projects forward from the wall surface is provided, when the plate slave unit 11 is installed with the top surface of the projecting portion as the installation surface W and the lid 15 facing downward, The hook 27 hangs down due to its own weight, and the rear surface of the hook 27 moves from the tilted posture to the standing posture where the rear surface of the hook 27 is approximately 60 °.

  Next, the usage mode of the plate slave unit 11 as described above will be described assuming that the plate slave unit 11 is installed with the wall surface as the installation surface W. The plate slave unit 11 has the wall surface in a posture with the lid 15 facing forward. The hook 27 is tilted as described above. Then, when connecting the hand slave unit 12, the hook 27 is lifted up to expose the insertion hole 24, the hand side connector 35 is inserted from the insertion hole 24, and connected to the plate side connector 20. . Thereafter, when lifting of the hook 27 is released, the hook 27 turns to the tilting posture side by its own weight, and takes the tilting posture with the cable 36 being passed through the space 32. When the hand slave unit 12 is not used, the hanger 37 provided in the hand slave unit 12 may be hooked on the hook 27 as shown in FIG. On the other hand, when the plate slave unit 11 is installed using the top surface as described above as the installation surface W, the hook 27 hangs down by its own weight and assumes a standing posture. Therefore, the hand-side connector 35 may be connected to the plate-side connector 20 without lifting the hook 27. Further, the hand slave unit 12 that is not used may be hung on the hook 27 in the standing posture as shown in FIG. The hand side connector 35 of the hand slave unit 12 is a so-called female connector having a receiving port 35a into which the pin 20a can be inserted.

  According to the nurse call slave unit 2 having the above-described configuration, the hook 27 for hooking the hand slave unit 12 can be rotated at a position where the tongue piece portion 28 covers the front of the insertion hole 24. In addition, the rear surface of the tongue piece 28 is shaped to bulge forward, and is inserted into the storage box 14 through the insertion hole 24 between the rear surface of the bulged tongue piece 28 and the insertion hole 24. A space 32 for allowing the cable 36 extending from the inserted hand side connector 35 to escape to the outside of the hook 27 is formed. Therefore, compared with the conventional one in which the hook 27 and the insertion hole 24 do not overlap with each other in the vertical or horizontal direction, the plate slave unit 11 and thus the nurse call slave unit 2 can be downsized. it can. Further, since the tongue piece portion 28 of the hook 27 in the tilted posture covers the front of the insertion hole 24, dust or the like enters the storage box 14 from the insertion hole 24 even if the wall surface is installed as the installation surface W. It is hard to do. Furthermore, when the hand-side connector 35 is inserted into the insertion hole 24, the hook 27 may be rotated to expose the insertion hole 24, so that the workability related to connector connection is not deteriorated.

  Further, in the plate slave unit 11, since the plate side connector 20 is attached in such a posture that the pin 20 a faces downward with an inclination angle of 24 ° with respect to the installation surface W, the hand side connector is attached to the plate side connector 20. Compared with the conventional connector structure which was inserted in the direction orthogonal to the installation surface W when connecting 35, the protrusion amount of the hand side connector 35 from the installation surface W can be made small. Therefore, it is difficult for a patient or a nurse to accidentally catch a hand, the connection between the plate-side connector 20 and the hand-side connector 35 is difficult to disconnect, and the effect that the plate-side connector 20 or the hand-side connector 35 is hardly damaged. There is. Further, when the hand slave unit 12 is hooked to the plate slave unit 11, the connection part between the plate side connector 20 and the hand side connector 35 is not easily obstructed, so the hand slave unit 12 can be easily hooked to the plate slave unit 11. There is also an effect that the handset 12 that has been left is difficult to drop off.

Furthermore, the plate-side connector 20 is attached using the space between the main board 17 and the switch board 19 in the storage box 14. Therefore, the space in the storage box 14 can be used effectively, and the plate slave unit 11 can be further reduced in size.
In addition, when the plate slave unit 11 is installed with the top surface as the installation surface W, the hook 27 hangs down by its own weight and takes a standing posture. Therefore, since the hand slave unit 12 can be hooked without providing a dedicated hook or the like used in the above-described installation mode, the plate slave unit 11 is further miniaturized, which is convenient and requires fewer parts. There is also an effect that it can be achieved.

  Note that the nurse call slave unit according to the present invention is not limited to the aspect of the above embodiment, and the gist of the present invention is not limited to the overall configuration of the nurse call slave unit but the configuration of hooks, connectors, and the like. As long as it does not deviate from the above, it can be changed as necessary.

For example, in the above-described embodiment, the posture of the plate-side connector 20 is such that the pin 20a faces downward with an inclination angle of 24 ° with respect to the installation surface W. It is also possible to configure to insert from the orthogonal direction. Moreover, even if it makes it incline, although it can change suitably regarding the inclination angle, it is preferable in it being in the range of 20-30 degree.
In contrast to the above embodiment, the plate-side connector 20 can be a female connector, and the hand-side connector 35 can be a male connector.
Further, the hook 27 can be configured not to move. Furthermore, even if the hook 27 is moved, a rotating mechanism is employed in the above embodiment, but a separate mechanism such as a slide mechanism may be employed instead.
In addition, when the bulging portion is formed on the hook 27, it is not necessary to form the bulging portion forward in the downward direction as in the above-described embodiment. There is no problem even if a bulging portion having a uniform protrusion amount is provided.
