【Example】

 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a preferred embodiment of the ultrasonic diagnostic apparatus according to the present invention, and FIG. 1 is a schematic diagram thereof.

In FIG. 1, an ultrasonic diagnostic apparatus (hereinafter referred to as an apparatus) 10 is provided with four casters 12 in the present embodiment, a front two wheels are provided with so-called turning casters, and a rear caster is provided. So-called fixed casters are used for the two wheels.

A handle 14 that is gripped when the device 10 is moved is provided on the back side of the device 10. Specifically, the handle 14 is composed of a horizontal rod-shaped member having a central portion or both ends supported by the device 10, as shown in FIG. 2 later.

In this embodiment, a brake lever 16 is rotatably attached to the handle 14, and as shown in FIG. 1, the brake lever 16 has its base end side pivotally supported by the handle 14. The moving end extends toward the back side of the device 10. When the brake lever 16 is in the horizontal state, the load on the caster 12 to be described later is set to 0, and the load applied to the caster 12 increases as the brake lever 16 gradually rotates downward from the horizontal state. .. Therefore, the caster 12 is almost locked when the brake lever 16 is completely lowered.

One end of a wire 18 for transmitting a braking action is connected to the brake lever 16, and the other end is connected to the brake mechanism shown in FIG.

In FIG. 2, a brake drum 20 is provided on each of the two casters 12 that are the rear wheels of the device 10, and a shoe (not shown) in the brake drum 20 is lifted by pulling up the brake bar 22 upward. The casters 10 are configured so that they spread outward or are narrowed inward, and as a result, an arbitrary load is applied to the casters 10.

The other end of the wire 18 is connected to substantially the center of the brake bar 22, and the wire 18 is pulled upward to pull the brake bar 22 upward from the connection point to execute the above-described braking action. To be done. The brake drum 20 has the same structure as that used in, for example, a bicycle. The adjuster screw 23 shown in FIG. 2 is a component that adjusts the amount of play until the brake works, and the initial setting is performed by this.

Therefore, by pushing the brake lever 16 downward, the wire 18 is pulled up, and the brake corresponding to the pulling amount is applied to the caster 12. As a result, when going down an inclined floor, for example, the device 10 can be moved while applying a constant load to the casters 12, and manpower can be reduced.

The brake mechanism shown in FIG. 2 is applied to the two rear casters in this embodiment, but a brake mechanism may be provided for the front casters, or the brake mechanism is applied to four wheels. It may be provided.

Returning to FIG. 1, a lock pedal 24 is provided in the device 10 of this embodiment. Specifically, a lock pedal 24 is provided below the rear side of the device 10 so that the lock pedal 24 can be depressed from the rear side of the device 10 as a starting point. The lock pedal 24 may have a plate shape, or may have a rod shape like the handle 14. FIG. 3 illustrates the concept of the rotation lock mechanism.

In FIG. 3, the rotation lock mechanism 26 comprises the lock pedal 24 and a lock mechanism 28 connected to the lock pedal 24. By depressing the lock pedal 24 downward, the caster contact portion of the lock mechanism 28 is depressed. 28a is pressed against the surface of the caster 12 made of a rubber-like member, and as a result, the caster 12 is completely locked. Then, the link mechanism connecting the contact portion 28a and the lock pedal 24 fixedly maintains the pressing action of the contact portion 28a on the surface of the caster 12 while the lock pedal 24 is pushed in. It is configured such that the pressed state is released by lifting the toe with the tip of the foot.

FIG. 3 shows the caster 12 on one side of the rear wheels, but a similar mechanism is also provided on the other side, and by depressing the lock pedal 24, the rear two wheels can be locked at the same time. You can Therefore, when it is necessary to make a temporary stop when going up an inclined floor, the person who moves the vehicle can easily lock the rear two wheels by stepping on the lock pedal 24. Therefore, the problem due to the one-sided effect described above can be solved.

In this embodiment, the brake mechanism and the rotation lock mechanism are provided at the same time, but of course only one of them may be provided. However, by adopting the two mechanisms at the same time in this way, reliable rotation control of the casters can be realized according to the situation.

[0029]

[Effect of the device]

 As described above, according to the present invention, the brake mechanism can apply a constant load to the casters, so that the ultrasonic diagnostic apparatus can be moved safely. Especially, it is effective that even a weak person can move the ultrasonic diagnostic equipment.

Further, according to the present invention, since the plurality of casters can be locked simultaneously by the rotation lock mechanism, the complicated lock of the casters, which has been performed individually, can be eliminated, and the ultrasonic diagnostic apparatus can be used in the middle of the slope. There is an effect that it can be stopped safely.
