Description

  The present invention relates to a lighting device and a hanging device for the lighting device.

  Conventionally, lighting devices that are used indoors and outdoors and suspended on structures such as ceilings and pillars are connected to a lighting fixture that contains a light bulb inside a reflector, and the hanging fixture is attached to the ceiling or ceiling. The structure is attached to a structure such as a column.

  As a hanging tool used in this lighting device, in addition to a rigid body for attaching a lighting fixture to a ceiling or a column, a hanging device having a structure using only a spring so as to cope with vibration and shaking is known. (For example, refer to Patent Document 1).

Japanese Patent Laid-Open No. 50-9495

  However, since the hanging tool used in the above-described conventional lighting device has a structure using only a spring so as to cope with vibrations and vibrations, not only vertical vibrations and vibrations but also horizontal vibrations and vibrations. It was a structure that acts directly on the spring.

  Therefore, in the conventional hanging tool, there is a possibility that the spring bends or breaks when vibration or shaking occurs in the horizontal direction.

Accordingly, the present invention according to claim 1 is a fish collecting apparatus in which a wire is stretched between a pair of telescopic columns of a support attached to a deck, and a lighting fixture is attached to the wire via a hanging tool. The hanging tool is constructed by projecting a connecting body for connecting to a lighting fixture from a casing for mounting on a wire , and houses a pair of upper and lower springs inside the casing, and a pair of upper and lower springs between the springs. The sphere is rotatably arranged between the two basins, and the connecting body connected to the sphere is protruded from the opening formed in the lower basin and the opening formed in the bottom surface of the casing. The pair of upper and lower springs increases the urging force of the lower spring than the urging force of the upper spring, and the casing is screwed with a lid on a hollow body that houses the pair of upper and lower springs inside. To, and you can adjust the biasing force of the upper and lower spring by clamping position of the lid, to absorb only the vertical vibration or swinging up and down of the spring, returning to the normal position by its own weight with respect to the horizontal direction of the vibration or shaking I decided to make it possible.

  And in this invention, there exists an effect described below.

  In other words, in the present invention, the upper and lower springs housed in the upper end side casing urge the ball connected to the lower end side connecting body to rotate freely, so that only vertical vibrations and vibrations are applied to the upper and lower springs. It is possible to make a structure in which horizontal vibrations and vibrations do not directly act on the upper and lower springs, and it is possible to prevent the suspension tool from being broken due to bending or breaking of the springs.

In particular, by increasing the urging force of the lower spring than the urging force of the upper spring, it is possible to satisfactorily absorb vertical vibrations and vibrations against gravity due to the heavy luminaire. In addition, the urging force of the upper and lower springs can be adjusted according to the tightening position of the lid body by screwing the lid body into a hollow body that houses a pair of upper and lower springs therein.
In addition, the vertical vibrations and vibrations are absorbed by the upper and lower springs so that the horizontal vibrations and vibrations do not act directly on the upper and lower springs. Failure can be prevented, and it can return to its normal posture with its own weight against horizontal vibration and shaking.
Furthermore, it is possible to easily change the mounting position (mounting height) of the luminaire simply by extending or retracting the support, and even if the ship vibrates, it can always irradiate a certain range and improve the fish collection performance. Can do.

  Hereinafter, a specific structure of the lighting device according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the lighting device 1 according to the present invention can be applied to a fish collecting device of a squid fishing boat 2, and a support 4 is attached to a deck 3 and 13 pieces are attached to the support 4. The lighting device 1 is attached with an interval in the front-rear direction. In addition, in the following description, although the case where the illuminating device 1 which concerns on this invention is applied to the fish collection apparatus of the squid fishing boat 2 is demonstrated to an example, it is not restricted to this, It can apply to various indoor and outdoor illuminations. Is.

  The support 4 has a wire 6 stretched between the upper ends of a pair of front and rear support columns 5 and 5, and each support column 5 and 5 is formed to be extendable.

  And the illuminating device 1 attaches | detaches the upper end part of the hanging tool 7 which incorporates a vibration absorption function to the wire 6 of the support body 4 so that attachment or detachment is possible, and attaches or detaches the attachment tool 9 of the lighting fixture 8 to the lower end part of the hanging tool 7. Install freely. Note that the lighting fixture 8 has an adapter 10 attached to a fixture 9, a reflecting umbrella 11 attached to the adapter 10, and a light bulb 12 accommodated inside the reflecting umbrella 11.

  As described above, in the lighting device 1, since the support columns 5 and 5 of the support 4 are formed to be extendable and retractable, the mounting position (mounting height) of the lighting fixture 8 can be adjusted simply by extending and retracting the support columns 5 and 5. It can be easily changed.

  Moreover, in the said illuminating device 1, since the lighting fixture 8 is connected to the support body 4 via the hanging tool 7 which has a vibration absorption function, a vibration can be absorbed with the hanging tool 7, and a lighting fixture. 8 can always irradiate a certain range. In particular, when the illuminating device 1 is used as a fish collection device, it is possible to always irradiate a certain range even if the ship vibrates, and to improve the fish collection performance.

  As shown in FIGS. 3 and 4, the hanging tool 7 projects a connecting body 14 for connecting to a lighting fixture 8 from a lower end portion of a casing 13 for attaching to a wire 6 of a support body 4 as a structure. It is made the composition made to do.

  The casing 13 has a hollow cylindrical lid 16 screwed to the upper end of the hollow cylindrical body 15 and a rectangular plate-like connector 17 connected to the wire 6 at the upper end of the lid 16. .

  The casing 13 accommodates a pair of upper and lower springs 18 and 19 inside, and a pair of upper and lower substantially disc-shaped trays 20 and 21 are disposed at the lower end of the upper spring 18 and the upper end of the lower spring 19. A spherical receiving surface is formed on the upper and lower receiving trays 20 and 21, and the spherical body 22 is rotatably disposed between the receiving surfaces of the receiving trays 20 and 21.

  The spherical body 22 is connected to the upper end of the connecting body 14 for connecting the lighting fixture 8, and is formed on the opening 23 formed on the receiving surface of the lower receiving tray 21 and the bottom surface of the body 15 of the casing 13. The connecting body 14 is projected from the opening 24.

  Thus, in the said illuminating device 1, the connection body 14 for connecting with the lighting fixture 8 protrudes from the casing 13 for attaching the suspending tool 7 to a structure, and also the inside of the casing 13 is comprised. A pair of upper and lower springs 18 and 19 are accommodated in the same, a pair of upper and lower trays 20 and 21 are disposed between the springs 18 and 19, and a spherical body 22 is rotatably disposed between the both trays 20 and 21. The connecting body 14 connected to the sphere 22 is projected from the opening 23 formed in the lower tray 21 and the opening 24 formed in the bottom surface of the casing 13.

  Therefore, in the illuminating device 1, the upper and lower springs 18 and 19 accommodated in the upper end side casing 13 urge the sphere 22 connected to the lower end side connecting body 14 in a freely rotating manner. Only the vibrations and vibrations can be absorbed by the upper and lower springs 18, 19, and the structure in which the horizontal vibrations and vibrations do not directly act on the upper and lower springs 18, 19 can be achieved. Failure of the suspending tool 7 due to breakage or breakage can be prevented. The lighting device 1 can return to a normal posture with its own weight against horizontal vibration and shaking.

  Moreover, in the said illuminating device 1, the thing of the same shape and urging | biasing force may be used as the upper and lower springs 18 and 19, and the thing of a different shape and urging | biasing force may be used.

  In particular, when the urging force of the lower spring 19 is larger than the urging force of the upper spring 18, the lower spring 19 counteracts gravity in the vertical direction against the gravity of the heavy lighting fixture 8. The vibration can be absorbed well.

  The urging force of the upper and lower springs 18 and 19 can be adjusted by the tightening position of the lid 16 of the casing 13.
