  Moreover, as shown in FIG. 1 and FIG. 2, the diameter dimension D1 of the electric head 1 and the diameter dimension D6 of the suction cup cover part 6 are set equally. Equal setting means that the diameter D1 of the electric head 1 is set to 90% to 110% of the diameter D6 of the suction cup cover 6. By providing them in this way, the support base 2 is not visible in the plan view of the reference state as shown in FIG.

  Moreover, the diameter dimension D5 of the suction cup 5 in the suction state is set smaller than the diameter dimension D6 of the suction cup cover portion 6. Specifically, the diameter dimension D5 of the suction cup 5 is set to 80% or more and less than 100% of the diameter dimension D6 of the suction cup cover portion 6. If it is 100% or more, there is a possibility that the suction cup 5 may appear to protrude from the suction cup cover portion 6 in a plan view, and the aesthetics may be impaired. . If it is less than 80%, there is a possibility that sufficient adsorption force cannot be obtained.

In FIG. 1, the electric head 1 uses the light transmitting member 15 as an operation button for turning on / off the LED lamp 18.
The light transmitting member 15 is attached to the casing member 16 so as to be slidable in the front-rear direction.
The reflecting plate member 17 includes a receiving portion 17a that receives the pressing force from the light transmitting member 15, an annular flat plate mounting outer peripheral edge portion 17b fixed to the casing member 16, an outer peripheral edge portion 17b, and a receiving portion 17a. A leaf spring portion 17c interposed between the outer peripheral edge portion 17b and the receiving portion 17a, an operation portion 17d provided integrally with the receiving portion 17a and disposed in the vicinity of the switch portion S of the electronic board K, have.

When the light transmitting member 15 is pressed by a user's finger or the like, the light transmitting member 15 presses the receiving portion 17a of the reflecting plate member 17, the plate spring portion 17c is elastically deformed, and the operating portion 17d is moved together with the receiving portion 17a. It is configured such that the operation portion 17d pushes the switch portion S of the electronic board K after sinking (moving backward).
When the user releases his / her finger or the like and the pressing force to the light transmitting member 15 is lost, the posture before the receiving portion 17a and the operating portion 17d are pushed by the elastic force of the leaf spring portion 17c of the reflecting plate member 17 is brought to the posture. Returning, the receiving portion 17a pushes up the light transmitting member 15 so as to return to the original position.
Further, the electronic board K is configured such that the LED lamp 18 is turned on when the switch portion S is pressed once, and the LED lamp 18 is turned off when the switch portion S is pressed again.

Next, the usage method (action) of the embodiment of the portable electric light of the present invention will be described.
As shown in FIG. 6, the outer peripheral edge 5 d of the suction cup 5 is constantly pressed by the double annular ridge 61 and in close contact with the installation plane G in a double seal shape in the suction state. The adhering state of the outer peripheral edge portion 5d is surely maintained with a high possibility that the suction cup 5 is easily peeled and loses its adsorption.
For example, as shown in FIG. 8, it is a vertical installation plane G and is attached with a strong adsorption force. The electric head 1 is held in a desired posture by the strong magnetic force attracted by the spherical head 3 of the support base 2 and the hemispherical recess 11a of the electric head 1.

  As shown in FIG. 9, the hemispherical concave portion 11a is brought into sliding contact with the spherical head 3, and the electric head 1 is freely swung to direct the irradiation direction in a desired direction. After the posture is determined, the user can use both hands and can easily perform reading, manual work, and the like.

Further, as shown in FIG. 10, the electric head 1 can be easily detached from the support base 2.
For example, nurses, caregivers, etc. who respond to calls such as nurse calls, guards, guards, etc., who respond to alarms can immediately remove the electric head 1 from the support base 2, carry it, and rush to the scene. Is possible. Moreover, since only the electronic head 1 can be carried, it is lightweight, small (compact) and excellent in portability.
In addition, by using the light transmitting member 15 as an operation button, the electric head 1 becomes a simple and gentle shape with an overall roundness like an egg with few sudden irregularities. It can be stored easily and smoothly in a pocket or the like, and the uncomfortable feeling when the electronic head 1 in the pocket touches the body is reduced.

  In the present invention, the design can be changed, and the installation plane G may be a vertical wall surface. One of the electric side magnet 12 and the base side magnet 32 may be omitted. Alternatively, one or both of the electric side magnetic member 11 and the base side magnetic member 31 may be formed of a magnet material having magnetic force, and one or both of the electric side magnet 12 and the base side magnet 32 may be omitted. That is, it is only necessary that one of the hemispherical recess 11a and the spherical head 3 has a magnetic force. Further, the bolt portion 22 may be provided on the spherical head 3 and the nut portion 21 may be provided on the suction cup 5. When the installation plane G is vertical, only the suction cup 5 is previously sucked by hand onto the installation plane G (performs preliminary suction), and the suction cup cover 6 is attached to the suction cup 5 like a lid. The spherical head 3 may be screwed and sucked so that the suction force of the suction cup 5 is increased by the suction cup cover 6.

  As described above, the portable electric light of the present invention includes the flat disk-shaped electric power head 1 in which the battery 19 and the LED lamp 18 are incorporated, and the support base 2 having the spherical head 3. 1 has a hemispherical recess 11a on the back surface 1b side and is detachably connected to the spherical head 3 of the support base 2 by magnetic force so that the irradiation direction can be easily held in a desired direction. . Irradiation direction can be changed easily and immediately. The electric head 1 can be detached from the support base 2 and can be carried immediately. Therefore, it is convenient for nurses in the hospital and guards of factories and offices. In addition, the support base 2 can be easily attached to the support base 2 without a tool, and the support base 2 can be used as a storage area for the electric head, so that the possibility of loss due to forgetting to return the electric head 1 carried can be reduced.

  Further, the support base 2 includes a suction cup 5 on the back surface 2b side, and connects the suction cup 5 and the spherical head 3 with a bolt / nut coupling 20 that can be reciprocated, and rotates the spherical head 3. Since the suction cup 5 is configured to be attracted to the installation plane G, it is not necessary to press the suction cup 5 directly and strongly, and the support base 2 can be easily attached to the installation plane G without a tool.

  The support base 2 includes a suction cup cover portion 6 having a circular shape in plan view, which covers the suction cup 5 in a cover shape and has a double annular ridge 61 on the back surface 6b side, and the spherical head 3 has a back surface 3b. The outer flange portion 36 is provided on the side, the suction cup cover portion 6 is pressed by the outer flange portion 36 by the screwing of the spherical head 3, and the outer peripheral edge portion 5 d of the suction cup 5 is formed by the double annular ridge 61. And the suction cup 5 is attracted to the installation plane G and the suction cup 5 is prevented from peeling off from the installation plane G. Therefore, the support base 2 can be securely attached to the installation plane G with a strong adsorption force. it can. The close contact state of the outer peripheral edge portion 5d that can be easily peeled off at the suction cup 5 and has a high possibility of losing the adsorption can be reliably held with a strong force. Even if a person or object hits the support base 2 inadvertently, it can be prevented from falling off or being displaced.

  Moreover, since the diameter D1 of the electric head 1 and the diameter D6 of the suction cup cover 6 are set to be equal, the support base 2 is not conspicuous and has a simple shape, so that any room can be aesthetically pleasing. It can be combined without feeling uncomfortable.
