(First embodiment)
First, with reference to FIG. 1, an outline of an ultraviolet irradiation device 1 according to the first embodiment will be described. FIG. 1 is an overall view of an ultraviolet irradiation device 1 according to the first embodiment. In order to simplify the explanation, FIG. 1 shows a three-dimensional orthogonal coordinate system including the Z-axis whose positive direction is upward in the vertical direction. Such an orthogonal coordinate system may also be shown in other drawings used in the following description.

The ultraviolet irradiation device 1 cures the coating agent applied on the floor by irradiating the coating agent with ultraviolet rays. As shown in FIG. 1 , the ultraviolet irradiation device 1 includes a light source section 20 , a frame 30 , a base 10 , a second handle 40 and a power supply section 50 .

Here, the UV irradiation device 1 allows the wheels of the pedestal 10 and the installer to pass after the light source part 20 has passed, thereby avoiding the wheels and the installer from stepping on the coating agent before application. Therefore, since the traveling direction of the ultraviolet irradiation device 1 during construction is uniquely determined, the light source unit 20 side viewed from the pedestal 10 is defined as "forward", and the builder side viewed from the pedestal 10 is defined as "rear". Define. Moreover, the direction orthogonal to the front-back direction may be described as the left-right direction.

The pedestal 10 is a so-called trolley and has wheels that move on the floor, and the wheels move the entire ultraviolet irradiation device 1 . A frame 30 is installed in front of the pedestal 10 , in other words, the pedestal 10 is installed behind the frame 30 . A light source unit 20 is installed on the frame 30, and the light source unit 20 irradiates the floor surface with ultraviolet rays, thereby curing the coating agent applied to the floor surface. The frame 30 preferably fixes the light source unit 20 so that the ultraviolet irradiation surface 26 (see FIG. 4) is substantially parallel to the floor.

A rod-shaped second handle 40 is installed on the top surface of the pedestal 10 . By moving the ultraviolet irradiation device 1 by holding the second handle 40, the worker irradiates the floor with ultraviolet rays while moving the ultraviolet irradiation device 1 on the floor surface. In addition, below, the base 10, the light source section 20, the frame 30 and the second handle 40 are collectively referred to as a light source unit.

The power supply unit 50 supplies power to the light source unit 20 . The power supply unit 50 converts, for example, power supplied from an outlet into power that meets the standards of the light source unit 20 . Moreover, as shown in FIG. 1, the light source section 20 and the power supply section 50 are connected by a flexible tube C. As shown in FIG. The flexible tube C includes an electric cord (not shown) that electrically connects the light source section 20 and the power supply section 50 . The material of the flexible tube C may be resin such as vinyl chloride or metal such as aluminum.

Moreover, as shown in FIG. 1, the power supply unit 50 itself also has wheels. Therefore, when the builder moves the light source unit, the power supply section 50 moves following the light source unit. In this way, by providing the power source unit 50 separately from the light source unit, it is possible to reduce the weight and size of the light source unit. As a result, it is possible to improve the operability for the installer and to realize the light source unit with a small turning radius.

Here, as described above, in the ultraviolet irradiation device 1, when the light source unit moves, the power supply section 50 moves following the light source unit. If the electric cord is not enclosed in the flexible tube C, that is, if the electric cord is exposed, the electric cord may be pulled and broken.

On the other hand, the ultraviolet irradiation device 1 can prevent disconnection of the electric cord by enclosing the electric cord in the flexible pipe C and applying tension to the flexible pipe C.

Next, the light source unit will be further described with reference to FIG. FIG. 2 is a side view of the light source unit according to the first embodiment; First, the pedestal 10 will be described. As shown in FIG. 2 , the pedestal 10 has a front wheel 11 and a rear wheel 12 installed on the bottom surface thereof, and an installation tool 13 to which a second handle 40 is attached to the top surface of the rear wheel 12 .

The front wheels 11 and the rear wheels 12 are examples of wheels, and function as moving mechanisms for moving the light source unit. In the example shown in FIG. 2, the front wheel 11 and the rear wheel 12 have substantially the same diameter, and the pedestal 10 is horizontally arranged.

The light source unit 20 includes a housing 21 , a first handle 22 , a claw portion 23 , a fan connector 24 and a light source connector 25 . The housing 21 is, for example, a metal box that houses a light source, a fan, and the like. The first handle 22 is a handle and is provided on the top surface of the light source section 20 . That is, while the second handle 40 is a handle for moving the entire light source unit, the first handle 22 is a handle for the light source section 20 . The builder can lift the light source section 20 by holding the first handle 22 .

Also, as will be described later, the light source unit 20 is detachably fixed to the frame 30 . In other words, when the light source unit 20 is fixed to the frame 30, the ultraviolet irradiation device 1 becomes a mobile ultraviolet irradiation device, and when the light source unit 20 is removed from the frame 30, it becomes a hand-held ultraviolet irradiation device. becomes.

When using the ultraviolet irradiation device 1 as a hand-held ultraviolet irradiation device, the worker can work while holding the first handle 22 of the light source unit 20 . This makes it possible to irradiate ultraviolet rays even in a very small space in which the entire ultraviolet irradiation device 1 cannot fit. The number of first handles 22 may be one or two. Also, the first handle 22 may be provided on the side surface of the housing 21 . Also, the orientation of the first handle 22 is not particularly limited, and may be in the front-rear direction or in the left-right direction. That is, the first handle 22 may be arbitrarily installed in consideration of the weight and operability of the light source unit, for example.

Here, "detachably fixed" means that the light source unit 20 can be fixed to the frame 30 without using a tool such as a screwdriver, and the light source unit can be removed from the frame 30 without using a tool. 20 can be removed.

That is, the ultraviolet irradiation device 1 according to the embodiment is provided with the first handle 21 in the light source unit 20, and by fixing the light source unit 20 in a detachable manner, the installer can easily switch between mobile and hand-held. becomes possible.

Therefore, according to the ultraviolet irradiation device 1 according to the embodiment, workability can be improved.

The claw portion 23 is provided on the side surface of the housing 21 . In the example shown in FIG. 2 , the light source section 20 is fixed to the frame 30 by hooking the claw section 23 onto the hook section 31 of the frame 30 . The fan connector 24 is a cable connector for connecting to a fan (not shown) installed in the housing 21 . The light source connector 25 is a cable connector for connecting to a light source (not shown). By cooling the light source with the fan, it is possible to suppress temperature rise due to heat generation of the light source.

In addition, in the ultraviolet irradiation device 1, the type of light source is not particularly limited as long as it can irradiate ultraviolet rays for curing the coating agent, but a metal halide lamp, a mercury lamp, or the like can be used. In the example shown in FIG. 2, the fan connector 24 and the light source connector 25 are respectively installed on the top surface side, but they may be installed facing the rear side surface.

The frame 30 mounts the light source section 20 and has a hook section 31 . The hooking portion 31 is, for example, a catch clip, and is attached from the frame 30 toward the light source portion 20 side.

Next, the pedestal 10 and the frame 30 will be further described with reference to FIG. FIG. 3 is a top view of the pedestal 10 and the frame 30 according to the first embodiment. As shown in FIG. 3, it is of a three-wheel type with two front wheels 11 and one rear wheel 12 .

In the ultraviolet irradiation device 1, compared to the case of a four-wheel type with two front wheels 11 and two rear wheels 12, by making it a three-wheel type, it is possible to realize a small turning radius of the light source unit. It is possible to improve the operability of the user.

The frame 30 includes an insertion hole 32 and an opening 33 in top view. The insertion holes 32 are through holes provided at four corners of the frame 30 . The light source unit 20 is fixed to the frame 30 by inserting the protrusion 27 of the light source unit 20 , which will be described later, into the insertion hole 32 . In addition, the ultraviolet rays emitted from the light source section 20 pass through the opening section 33 and irradiate the floor surface.

By the way, as described above, in the ultraviolet irradiation device 1 , the pedestal 10 passes after passing through the light source section 20 . Therefore, the effective irradiation width W1 of the ultraviolet rays by the light source unit 20 is designed to be smaller than the wheel width W2 indicating the width through which the wheels pass. Here, for the sake of simplicity, the effective irradiation width W1 is the width of the opening 33. As shown in FIG.

In other words, by making the effective irradiation width W1 larger than the wheel width W2, the wheel passes over the coating agent after being cured by the ultraviolet rays, thereby preventing the wheel from passing over the coating agent before application. be able to.

Next, the light source section 20 will be further described with reference to FIG. FIG. 4 is a perspective view of the light source unit 20 according to the first embodiment viewed from the irradiation surface 26 side. In addition, the light source part 20 is shown typically in Fig.4 (a). As shown in FIG. 4A, the light source section 20 has protrusions 27 at four corners on the irradiation surface 26 side. The projecting portion 27 faces vertically downward from the irradiation surface 26 , that is, is inserted into the insertion hole 32 of the frame 30 when the light source portion 20 is installed in the frame 30 .

That is, as shown in FIG. 2 , the light source section 20 is fixed to the frame 30 by the claw section 23 and the hook section 31 , and is also fixed by the projection section 27 and the insertion hole 32 . As a result, the light source unit 20 can be firmly fixed to the frame 30 without screwing the light source unit 20 to the frame 30 .

Here, the projecting portion 27 can absorb vibration transmitted to the light source portion 20 by using, for example, a rubber member. However, deterioration of rubber members is accelerated by ultraviolet rays. For this reason, as shown in FIG. 4B, the ultraviolet irradiation device 1 according to the embodiment suppresses deterioration of the rubber member due to ultraviolet rays by covering the rubber member forming the protrusion 27 with a light-shielding cover 28. can be done. Note that the cover 28 may be attached to the frame 30 in advance, or may be attached to the protrusion 27 in advance.

The term "light-shielding" as used herein means that the transmittance in the ultraviolet region is low, and aluminum, for example, can be used as the light-shielding cover.

Next, the second handle 40 will be explained using FIG. FIG. 5 is a diagram showing the range of motion of the second handle 40 according to the first embodiment. As shown in FIG. 5, the second handle 40 is installed so that the angle can be adjusted in the front-rear direction. The example shown in FIG. 5 shows a case where the range of motion of the second handle 40 is approximately 90° in the vertical direction from the floor surface.

In this way, by providing the second handle 40 with a movable range, the builder can adjust the angle of the second handle 40 according to his or her height, so that the builder can perform construction in a natural posture. becomes possible.

Note that the range of motion of the second handle 40 is not limited to the example shown in FIG. can be Also, for example, the second handle 40 may be a handle whose length is adjustable.

As described above, the ultraviolet irradiation device 1 according to the first embodiment includes the light source section 20, the frame 30, the base 10, and the second handle 40. The light source unit 20 has a first handle 22 and an irradiation surface 26 for irradiating ultraviolet rays. The frame 30 detachably fixes the light source unit 20 with the irradiation surface 26 facing the floor. The base 10 is fixed to the rear of the frame 30 and has wheels 11 and 12 . A second handle 40 is provided on the base 10 . Therefore, according to the ultraviolet irradiation device 1 according to the embodiment, workability can be improved.

By the way, in the above-described embodiment, the case where a total of three wheels, ie, the two front wheels 11 and the one rear wheel 12 are provided, has been described, but the present invention is not limited to this. That is, a total of four wheels including two front wheels 11 and two rear wheels 12 may be provided.

Specifically, as shown in FIG. 6, in the ultraviolet irradiation device 1A, the power source section 50 is installed on the pedestal 10A. Therefore, the worker performs the work while pushing the power supply unit 50 in addition to the light source unit 20 .

For this reason, the ultraviolet irradiation device 1A includes a U-shaped second handle 40A. As a result, the worker can move the ultraviolet irradiation device 1A while gripping the second handle 40A with both hands, so that the force can be efficiently transmitted to the ultraviolet irradiation device 1A.

The ultraviolet irradiation device 1A is of a four-wheeled type with two front wheels 11 and two rear wheels 12, but the number of wheels is not particularly limited, and may be three-wheeled or five-wheeled. It may be more than the formula.

Although not shown here, in the ultraviolet irradiation device 1A, the light source portion 20 is fixed to the frame 30 by the claw portion 23, the hook portion 31, the projection portion 27, and the insertion hole 32, similarly to the ultraviolet irradiation device 1. be done.
