In addition, the load cell 6 shown in FIG. 2 is installed in the main body base 3, and a load (for example, the weight of an animal or an operator) generated on the base 2 can be detected through the base cover 5. The load cell 6 corresponds to a detection device for detecting an obstacle according to the present invention.
A micro switch may be used as a method of detecting an obstacle inexpensively. Specifically, a movable contact is provided on the back surface of the base cover 5, an electrode (not shown) is provided below the movable contact, and a spring (not shown) supporting the weight of the base cover 5 is provided. When a load exceeding the weight of 5 is generated and the base cover 5 moves downward against the biasing force of the spring, the movable contact contacts the electrode and the electric circuit conducts to detect an obstacle. If a micro switch is used, it can be detected even when the small dog comes in contact with the base cover 5, and if the operator wants to stop the movement of the table 10 urgently, it can be detected by stepping on the base cover 5.

  A table 10 having a rectangular shape in plan view, which is larger than the base 2, is disposed above the base 2, and the table 10 can be moved up and down with respect to the base 2. The base 2 is provided with, for example, three types of foot switches 4a, 4b and 4c. The foot switch 4a is depressed when the table 10 is lowered, and the foot switch 4c is depressed when the table 10 is lifted. When the foot switch 4b (also referred to as memory / auto switch) is depressed, movement of the table 10 to the lowermost position (also referred to as introduction / retraction position) or memory position preset by the operator (above the introduction / retraction position) The movement to position) can be switched alternately.

Further, the LEDs 16 shown in FIG. 2 are provided inside the chassis covers 15a and 15b. The LED 16 lights up in blue or red based on the detection result of the load cell 6.

Next, when the table 10 is positioned at the predetermined height shown in FIG. 1 and the foot switch 4a is depressed, the elevation processing unit 46 shown in FIG. 2 rotates the elevation motor 43 in a predetermined direction. As a result, the table 10 is lowered to approach the base 2. When it is desired to stop the descent of the table 10, the foot switch 4a is released. During depression of the foot switch 4a, the table 10 is lowered, and when the table 10 reaches the introduction and exit position, the rotation of the lift motor 43 is stopped from the detection result of the lower proximity sensor 71. Since the clutch 44b is brought into contact with the clutch 44a, the animal can be slow stopped without being surprised. When the introduction and exit position is reached, the lift motor 43 remains stopped even if the foot switch 4a is kept depressed or repressed.
On the other hand, when the foot switch 4c is depressed, the table 10 is raised, and when the upper proximity sensor 47 detects that the table 10 is most separated from the base 2, the rotation of the elevating motor 43 is stopped. At this time, the lift motor 43 remains stopped even if the foot switch 4c is kept depressed or repressed.
When the table 10 is similarly located at the predetermined height shown in FIG. 1 and the memory / auto switch 4b is depressed, the lower proximity sensor 71 detects that the table 10 has reached the introduction and withdrawal position. The rotation of the lift motor 43 is stopped. Thereafter, the tilt motor 70 rotates and the table 10 starts to tilt forward.

On the other hand, when the memory / auto switch 4b is depressed while the table 10 has reached the introduction and exit position and is already inclined forward, the tilt motor 70 is first rotated and the table 10 starts to be inclined backward. . Since the screw portion 63b of the tilt rod screw 63 moves upward and pushes up the support receiving portion 62b of the movable chassis 62, the table 10 returns to the horizontal position. When the horizontal position of the table 10 is detected by the rising limit switch 73a shown in FIG. 2, the rotation of the tilt motor 70 is stopped. Thereafter, the lift motor 43 rotates and the table 10 starts to rise. When the table 10 is automatically stopped at the memory position, the rotation of the lift motor 43 is stopped. When the table 10 is at the introduction and withdrawal position but is not inclined forward, when the memory / auto switch 4b is depressed, the table 10 is raised to the memory position.

  As shown in FIG. 7A, when the table 10 is lowered toward the base 2 and it is detected by the lower proximity sensor 71 that the table 10 has reached the introduction and withdrawal position, the tilt processing unit 72 shown in FIG. The tilt motor 70 is rotated in a predetermined direction. As a result, the screw portion 63b of the tilt rod screw 63 moves downward, pulls the support receiving portion 62b of the movable chassis 62 downward, and the movable chassis 62 rotates with respect to the fixed chassis 61. Became inclined. When it is detected by the sleep limit switch 73 b that the movable chassis 62 has come closest to the fixed chassis 61, the rotation of the tilt motor 70 is stopped. Specifically, as shown in FIG. 7 (B), the table 10 is an end on the side (back side of the table 10) where the end on the front side of the table 10 is near the post cover 24 and is far from the column cover 24 It is located lower than.

Furthermore, when the table 10 leans forward, as shown in FIG. 7B, the slope 17 can be pulled downward. The tip of the slope 17 can reach the floor of the examination room.
As described above, when the table 10 comes closest to the base 2, the table 10 leans forward, so even a large animal or old dog, for example, can easily get on and off the table 10 by itself.

FIG. 8 is a perspective view of an examination table according to a second embodiment of the present invention. In FIG. 8, in order to make the columns 21 and the column guides 22 easy to see, the description of the column cover 24, the support upper plate 35, the table 10 and the like described in FIG. 1 is omitted.
The column guide 22 moves up and down together with the table. For this reason, as shown in FIG. 8, if the operationless lamp 90 is installed on the column guide 22, the distance from the table to the operationless lamp can be maintained constant regardless of the height of the table. For this reason, while being able to respond to the request that an operator wants to install an operating light in a medical examination in order to ensure a visual field, the height adjustment operation of an operating light can be reduced.

Further, the examination table may have a lighting processing unit (not shown). When the table 10 is at the introduction and exit position, when the memory / auto switch 4b shown in FIG. 1 is depressed, the table 10 ascends to the memory position and stops when the memory position is reached. When the table 10 is stopped, the shadowless lamp 90 is turned on. If the table 10 is not at the introduction and exit position, the shadowless lamp 90 is turned off when the memory / auto switch 4b is depressed. The table 10 stops after reaching the introduction and exit position and tilting forward. As described above, the shadowless light 90 is turned on when performing a medical examination or surgery, and is turned off after the medical examination or surgery is performed, which also contributes to securing the visual field of the operator.
Alternatively, it may be turned on / off according to the load generated on the table. Specifically, the lighting processing unit turns on the shadowless lamp 90 when a load equal to or greater than a predetermined value is generated on the table 10 based on the detection result of the weight 13 and the load not greater than a predetermined value does not occur. If you turn off the light, you can prevent it from being forgotten.
