Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caster for preventing casters provided at the lower end of a device from being stopped by being obstructed by an obstacle on the floor.

[0002]

2. Description of the Related Art Equipment with casters is widely used in medical equipment, office equipment, etc., and moves by being pushed manually on the floor, but if there is something like an electric cord on the floor, This is an obstacle, and there is the inconvenience that you cannot get over. Among various types of medical equipment, for example, in anesthesia machines, many electric cords from the power supply unit and tubes for sending various gases from the main pipe or for returning excess gas are connected and dragged. However, since it moves to the place of use, depending on the direction of movement, the caster may climb onto the cords and tubes of its own machine, and may climb onto other types of equipment, etc., and movement is likely to be impeded. Moreover, if the tubes are ridden, they may be crushed and the flow of gas or the like may be blocked.

In order to prevent this condition, in some hospitals, a caster of the anesthesia machine is fitted with a short cylinder in the longitudinal direction to form an obstacle device, and the obstacle device pushes away the obstacle. ing. However, in order to fit the cylinder to the caster, the caster must be tilted or lifted to float the caster from the floor surface, and the cylinder should be inserted below the caster to fit the caster. Since an anesthesia machine generally has a weight of several tens of kilograms, it takes a few people to fit the caster to the caster without the cylinder attached, which is not an easy task.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to obtain a distractor which can be mounted without floating casters and a mounting method thereof.

[0005]

According to a first aspect of the present invention, there is provided a disintegrator for solving the above-mentioned problems, wherein a caster provided at a lower end of the device is fitted with a tubular body in a vertical direction to form the tubular body. In a caster obstruction device configured to be pushed and moved by a caster, a plurality of divided pieces obtained by vertically dividing the tubular body are united around the caster to form a tubular body, Can be easily mounted on casters.

[0006] Further, as described in claim 2, the method for mounting the obstacle stopper is a caster obstacle stopper in which a caster provided at the lower end of the device is fitted vertically with a cylinder body for obstacle prevention. In a method of mounting a container, a caster of the device is stationary on a floor surface where the device is used, and a plurality of divided pieces obtained by vertically dividing the cylinder are united around the caster to form a cylinder. It is characterized in that it can be easily mounted on the floor surface where the equipment is used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Means for carrying out the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a schematic anesthesia machine, 2 is a floor surface on which the anesthesia machine 1 is placed and moves, and on the lower surface of the anesthesia machine 1, four casters 3 are rotated with a shaft 4. It is attached by a formula holder 5. On the side surface of the anesthesia machine 1, an electric cord 6, oxygen, air,
Tubes 7 and 7 for sending laughing gas and returning excess gas.
Are connected and extend on the floor surface 2 to a power source part (not shown) provided at a fixed position and a main part.

Reference numeral 8 denotes an obstacle device fitted to the caster 3, which is mounted by combining two divided pieces 8a and 8b as shown in FIGS. 2 (A) and 2 (B). The obstruction device 8 is formed of a plastic material in an oval shape. An outer locking piece 9 is formed on one divided piece 8a side, and an inner locking piece 10 is formed on the other divided piece 8b in a tapered shape. And the divided piece 8b has a slight elasticity that acts in the spreading direction.
Both locking pieces 9 and 10 are pressed and joined. FIG. 2
As shown in (C), by providing each locking piece 9, 10 with a snap portion 11 composed of a concave portion and a convex portion, it is possible to prevent vertical displacement and further secure the united state.

In the embodiment shown in FIG. 3, the obstruction device 12 has a circular cross section, and the semicircular divided pieces 12a and 12b connect one end side with a hinge 13 and the other end side with the locking piece 9 ,. The hinge 13 has the same structure as the hinge 10 and is opened and closed around the hinge 13. As a result, the split pieces 12a, 12b are engaged with the locking pieces 9, 10 from the split state in which the locking pieces 9, 10 are disengaged. The combined state can be changed quickly.

In the embodiment shown in FIG. 4, the obstruction device 14 has a pipe joint shape with a flange, and the divided pieces 14a, 1
A flange 15 is connected to 4b. This divided piece 14
The casters are sandwiched by a and 14b, and the arc-shaped connecting plate 16 is overlapped on the flanges 15 and 15 and fixed by screws 17.

In the embodiment shown in FIG. 5, the rejector 18 is composed of divided pieces 18a and 18b having the same shape.
18b is provided with a V-shaped peak portion 19 and a valley portion 20 on the divided surface.

An adhesive 2 is applied to the surface of the ridges 19 and the valleys 20.
Apply 1 and surround the caster 3 with the divided pieces 18a and 18b,
The peaks 19 and the valleys 20 are brought into close contact with each other and the adhesive 21 is solidified to be united.

Although several examples of the obstruction device are shown above, various forms can be adopted within the scope of the means described in claims 1 and 2. For example, the heights of 8, 12, and other handicapped devices are not limited to the heights shown in the figure, and can be set to a height in the range from the vicinity of the axle 4 to the vicinity of the bottom surface of the device. When increasing the height, The portion intersecting with the rotary holder 5 may be cut out, or the obstacle holder may be pushed by the rotary holder 5. The present invention can also be implemented in casters mounted on fixed holders.

[0014]

As is apparent from the above description, according to the means of claims 1 and 2, the caster 4 can be mounted with the jamb without being lifted from the floor, so that the weight of the equipment can be reduced. It is extremely convenient because it can be worn by one person regardless of the situation, and there is an advantage that the caster can easily prevent the rider from riding on the obstacle and stopping or deforming the obstacle.
