The operation of the caster fixing mechanism configured as described above will be described. During normal use, the pedal 309 is in a horizontal state, so that the gear 304 and the lock member 305 do not mesh with each other. For this reason, the casters 302 can rotate freely and can change the direction freely.

When moving straight, first, the endoscope inspection bed 1H is turned in the direction in which
02 in the traveling direction, the pedal 309 is lifted, and the slide stay 306 is slid in the direction of reference numeral 312 so that the lock member 305 provided at the tip of the slide stay 306 bites into the gear 304 to fix the direction of the caster 302. And give it propulsion to go straight.

As described above, when the moving direction of the endoscopic examination bed is determined, the caster can be fixed in a desired direction by operating the pedal when the traveling direction is determined.
This eliminates the need for an operation and force for constantly orienting the endoscopic bed. Further, by providing the pedals on both sides of the frame of the endoscopy bed, the pedals can be selected according to the work situation.

FIGS. 25 and 26 illustrate the configuration of an endoscope inspection bed using a commercially available switchable caster. FIG. 25 is an explanatory diagram showing the schematic configuration of an endoscope inspection bed. 26 is an explanatory view showing a caster fixing mechanism.

As shown in FIGS. 25 and 26, the base frame 351 of the endoscopic examination bed 1J of this embodiment is
It is supported by commercially available switchable casters 352.

The casters 352 are “freely rotated”, “fixed only in the direction” with respect to the base frame 351,
The three states of "the rotation of the wheel is also fixed" can be switched.
This can be done by rotating 53.

That is, this shaft 3
A rotation lever 354 that rotates together with 53 is fixed. Independent lever 35 independent of the caster 352
5 is fixed to a frame 351 by a bearing (not shown), is rotatable, and is connected to a rotation lever 354 and an independent lever 355 by a shaft 356.

On the other hand, the pedal 357 is arranged at a position where a person who pushes to move the endoscopic examination bed 1J can step on it.

That is, the pedal 357 of this embodiment is
The lever 358 is fixed on the rear side of the caster 365 at the rear of the base frame 351 and rotates together with the pedal 357.

The lever 358 and the independent lever 355
Are connected by a connection shaft 359. The switching shafts 353 of the left and right casters 352R and 352L positioned in the forward direction are connected by a shaft 360, and the switching shaft 353 operates simultaneously on the left and right casters 352R and 352L.

Incidentally, the pedals 357 may be provided on both sides of the base frame 351 so that the casters 352 can be operated from both sides of the endoscopic inspection bed 1J.

The operation of the traveling direction changing mechanism configured as described above will be described. When the pedal 357 is lifted, the connecting shaft 359 is pulled, and the rotating lever 354 rotates clockwise. As a result, the casters 352
Since only the direction is fixed, the endoscope inspection bed 1J does not care about the direction, but only goes straight forward by applying a propulsive force.

By appropriately adjusting the fixed positions of the shaft 356 and the connecting shaft 359 on the independent lever 355, the casters 35 having various switching forces can be adjusted.
2, and the depression angle of the pedal 357 can be set freely.

As described above, by operating the pedal provided on the endoscope inspection bed, the caster located in front can be set in the “only fixed direction” state. It is possible to drive straight ahead stably by giving propulsion without worrying about the direction. As a result, the labor of a nurse or the like operating the endoscopy bed is greatly reduced.

Further, in order to make the vehicle straight forward stably, it is necessary to fix the direction of the caster located in front of the traveling direction, but according to the present embodiment, the "freely rotating" state and the "only direction fixing" state. Because the device to switch between and is under the foot of the person pushing the endoscopy bed, during the movement, for example, when turning a corner and then there is a long corridor, stop the endoscopy bed each time Since there is no need to operate the casters by turning to the front in the traveling direction, smooth movement of the endoscopic inspection bed can be realized.

Further, when mechanisms are provided on both the left and right sides, it is only necessary to depress the pedal which is easier to depress according to the situation at that time, so that the work can be performed efficiently.

By the way, in a bed, particularly a medical bed, in order to prevent a patient or a subject from dropping from a bed,
A fall prevention fence (side guard) is provided.

Conventionally, as a side guard provided on a bed, there has been known a side guard which can be integrally stored on the lower part of the bed on one side.
