Description

  The present invention relates to a partition lifting mechanism, and more particularly to a partition lifting mechanism in a dental clinic.

A conventional partition is generally fixed at a predetermined position in a dental clinic or movably arranged. The purpose of these partitions is to partition the medical chairs so that the next patient cannot be seen during the treatment, and has a sufficient height.
JP2002-201742 JP2002-349145

  Since the conventional fixed partition cannot move, the space cannot be effectively utilized by moving to one side. Moreover, even if it is mobile, there is a problem such as feeling a pressure when stored because it is tall.

Therefore , the problem to be solved by the present invention is that when the partition is not used, the partition is stowed and stored, and can be moved. Is to provide a partition that can.

  The present invention is characterized in that the partition can be stored in an opening / closing door of a storage cabinet for storing a dental care unit, and the partition can be moved up and down in conjunction with opening / closing of the opening / closing door.

  Since the partition raising / lowering mechanism of the present invention can store the partition in the opening / closing door of the storage cabinet that stores the dental care unit and can lower the height, it does not feel a feeling of pressure in the room. Further, when using a partition, the partition can be raised and lowered in conjunction with opening and closing of the door, so that it is not necessary to raise and lower the partition manually. Accordingly, there is an advantage that when the partition is not used, the partition does not become an obstacle in the room and the indoor space can be effectively used.

The purpose of facilitating the storage and usage of the partition was realized by storing the partition in the open / close door of the storage cabinet that stores the dental care unit, and moving the partition up and down in conjunction with the opening and closing of the revolving door. .

1 and 2 show Embodiment 1 of the present invention, FIG. 1 is a view showing a partition attached to a revolving door of a storage cabinet for storing a dental care unit, and FIG. 2 is a front view showing a pantograph type lifting means. .

  As shown in FIG. 1, a guide wheel 4 that rotates in contact with the floor surface 16 is provided at the lower end of the rotary door 3 that constitutes the front surface of the storage cabinet 2 that stores the dental care unit 1. In this embodiment, a panel type partition 5 is housed in the revolving door 3, and a pantograph type elevating means for raising and lowering the partition 5 in conjunction with the rotation of the guide wheel 4 that rotates by opening and closing the revolving door 3 is provided on the revolving door 3. It is a thing.

  As shown in FIG. 2, the pantograph type lifting / lowering means is composed of an X-type pantograph type link mechanism 6 in which substantially central portions of the two links a and b are rotatably connected via pins 7. This link mechanism 6 has a horizontally elongated hole 8 in which one link a lower end of two links formed in an X shape is rotatably connected to the lower end of the door frame 10 and the other end is formed at the lower end of the partition 5. Are slidably engaged with each other via a slide pin 9. The upper end of the other link b is rotatably connected to the lower end of the partition 5. On the other hand, a screw shaft 12 and a screw shaft are rotated along a lower side of the door frame 10 through a pair of gears 11 by the rotation of the guide wheel 4. A female screw 13 that is engaged with the screw 12 and moves forward and backward is provided, and the lower end of the link b is rotatably connected to the female screw 13.

  The pantograph-type link mechanism 6 having this configuration is such that the rotation of the guide wheel 4 that rotates by opening and closing the rotary door 3 is transmitted to the screw shaft 12 through the gear 11, and the female screw 13 that is screwed to the screw shaft 12 is horizontally aligned. The one end of the link b moves forward and backward in the horizontal direction. Thereby, the partition 5 is moved up and down in conjunction with opening and closing of the rotary door 3 at the upper ends of the links a and b. The rotation shaft 14 of the guide wheel 4 is higher in position than the axis of the screw shaft 12 provided on the lower surface of the rotary door 3, so that the rotation can be transmitted by the pair of gears 11. Further, a motor 15 may be connected to the rotating shaft 14 of the guide wheel 4 so that the rotary door 3 can be opened and closed by driving the motor.

3 to 5 show a second embodiment of the present invention, FIG. 3 is a front view showing a timing belt type lifting means, FIG. 4 is a side view of the timing belt, and FIG. 5 is an AA view showing a connecting metal part. It is an expanded sectional view This embodiment is an example using timing belt type lifting means instead of using the lifting means of the pantograph type link mechanism in the first embodiment.

As shown in FIG. 4, the timing belt type lifting / lowering means includes a timing belt mechanism 27 that lifts and lowers the partition on the timing bell 18 that meshes with the upper and lower timing pulleys 17 and reliably transmits the rotation. In this embodiment, as shown in FIG. 3, the timing pulley 17 and the timing belt 18 are provided on both sides of the door frame 19, the timing pulleys 17 on the lower sides are connected by the synchronization shaft 20, and the synchronization shaft 20 is a pair of It is connected to the rotating shaft 14 of the guide wheel 4 via a gear 21.

In addition, the lower part of both ends of the panel type partition 22 is fixed to the timing belt 18 by a connecting bracket 23 and a fixing bracket 24 as shown in FIGS. 3 and 5, and a slide provided on the door frame 19 side is fixed to the fixing bracket 24. A slider 26 slidably engaged with the guide rail 25 is provided, and the partition 22 moves up and down with the slide guide rail 25 as a guide by the rotation of the timing belt 18. As a result, the partition 22 can be moved up and down in conjunction with the opening and closing of the rotary door 3.
In the first and second embodiments, the example using the panel type partition has been described. However, the partition type is not limited to the panel type, and any partition suitable for raising and lowering such as a partition in which a curtain is stretched on a frame can be used. Moreover, a glass plate, a plastic plate, etc. can also be used.

  In this embodiment, an example using the timing belt type lifting / lowering means has been described. However, the belt is not limited to the timing belt, and other belts such as a V belt may be used. Furthermore, the present invention is not limited thereto, and chain type lifting means using a chain and a sprocket may be used. In this case as well, the same effect as that of the timing belt type elevating / lowering means is obtained, so that redundant description is omitted. Further, the opening / closing door is not limited to a revolving door, and may be a sliding door.

It is a figure which shows the partition attached to the rotation door of the storage cabinet which accommodates a dental treatment unit. Example 1 It is a front view which shows a pantograph type raising / lowering means. Example 1 It is a front view which shows a timing belt type raising / lowering means. (Example 2) It is a side view of a timing belt. (Example 2) It is an AA arrow expanded sectional view which shows a connection metal fitting part. (Example 2)
