Abstract

PURPOSE:To improve the operationability at the time of drawing and housing a lighting tool by removing a member to be adsorbed which is adsorbed by a fixing magnet with operation of an operating tool so that the lighting tool projects to the front of a shelf. CONSTITUTION:At the time of drawing an under-shelf luminaire to the front of a shelf 2, when an operating button 7a of an operating tool 7 is pushed, a fixing magnet 14 moves to the back of the shelf 2, and a member 18 to be adsorbed is removed from the fixing magnet 14. Since the frictional force of a sliding part of a support 6 and a lighting tool 5 is small and, furthermore, dislocation of a center-of-gravity position of the lighting tool 5 and a lighting tool rotary shaft 8 is large, the lighting tool 5 tries to move into the stabilized condition. Next, the support 6 is drawn by a drawing spring 19 to draw the lighting tool 5. At the time of housing the lighting tool 5, when the lighting tool 5 is pushed to the shelf 2, the member 18 to be attracted is attracted by the fixing magnet 14 and the lighting tool 5 is housed. A drawing operation at the time of using an under-shelf luminaire can be performed easily, and the operationability at the time of housing is good.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an under-shelf lighting fixture, and particularly to an under-shelf lighting fixture that is attached to the underside of a shelf such as a bookshelf of a study desk so that it can be pulled out forward. Such is the case.

[Conventional technology]

In the study desk 1 shown in FIG. 6, it has been known that an under-shelf lighting fixture is attached to the bottom surface of the column 2 to illuminate the top surface of the desk.

In such cases, conventionally, for boat fishing, a straight tube fluorescent lighting fixture is fixed under the shelf, and a light fixture configured as an incandescent spotlight is attached to the tip of a support made of flexible tube, etc., and can be freely pulled out to the front of the shelf. A straight tube fluorescent light fixture provides general illumination of the desk top, while an incandescent spotlight provides local illumination depending on the task.

[Problem to be solved by the invention]

Conventionally, as mentioned above, under-shelf lighting equipment that has a light fixture as an incandescent spotlight has good operability because the resistance created by the structure of the support is strong when pulling out the light fixture to the front of the shelf or storing it. The problem was that there was no.

The present invention has been made in view of the above-mentioned background, and an object thereof is to provide an under-shelf lighting fixture with good operability when the light fixture is stored in a drawer.

[Means to solve the problem]

The under-shelf lighting equipment according to the present invention has a column whose rotation angle is regulated, which is rotatably protruded upwardly behind the center of gravity of the light fixture equipped with a lamp, and the vicinity of the upper end of the column is rotated from the lower end to the front surface of the shelf and from the front surface of the shelf. For fixing the lamp by attaching it so that it can move freely, setting the frictional resistance of the upper end of the pillar to be larger than the frictional resistance of rotating the lamp at the lower end of the pillar, and fixing the lamp by adhering to an adherend provided on the upper surface of the lamp. The magnet is attached to an operating tool arranged on the front surface of the shelf with an operating button for removing the adherend attracted to the fixing magnet.

[Effect]

According to the present invention, the adherend attracted to the fixing magnet is detached by operating the operating tool, and the lamp protrudes toward the front of the shelf.

[Embodiment] FIGS. 1 to 5 show embodiments of the present invention, which will be explained below based on the drawings.

The undershelf lighting fixture of this embodiment is used for a study desk as shown in FIG.
2 is a shelf of the study desk 1, and an undershelf lighting fixture is attached to the lower surface of the shelf board of the shelf 2.

The undershelf lighting fixture 3, as shown in FIGS. 1 and 2,
The lamp 5 is equipped with a socket inside and an incandescent lamp 4 is attached to it.
It is suspended and supported by a pair of supports 6 below the shelf 2. When the light fixture 5 of this under-shelf lighting fixture 3 is stored, its front surface is lowered slightly backward than the curtain tff12a on the front surface of tIA2, and it is located almost directly under the shelf 2, and when it is pulled out, its front surface is lowered to the front curtain plate on the front surface of tIA2. It protrudes forward from 2a and is suspended with a space between it and the shelf 2. The curtain plate 2a of the shelf 2 is provided with an operation button 7 of an operation tool 7 for operating the drawer of the lamp 5.
When a is pressed, the operating tool 7 operates and the lamp 5 comes out to the front of the shelf 2.

Next, the detailed configuration and operation of this embodiment will be explained based on FIGS. 3 to 5.

The support column 6 on which the lamp 5 is suspended is made of a material such as a steel plate that is attracted to a magnet, and has a lamp rotation shaft 8 near its lower end that pivots the lamp 5 on the rear side of the lamp 5. It has an arc-shaped lamp rotation regulating groove 9.

The column 6 also has a column rotation axis 10 near its upper end, and an arcuate column rotation regulating groove 11 centered on the column rotation axis 10. Attached to the lower surface of the shelf 2 is a fixture 12 on which the column 6 is pivoted about the column rotation shaft 10. A stopper pin 5a provided upright on the side of the lamp 5 is inserted into the lamp rotation regulating groove 9, and serves as a stopper to prevent the lamp 5 from hanging down.
This prevents the front end of the lamp 5 from hanging down when it is pulled out forward. In addition, the pillar rotation regulating groove 1
1 includes a stopper pin 12a erected on the fixture 12.
is inserted, and when the lamp 5 is pulled out in front of the shelf 2, the position of the lamp 5 is regulated by regulating the amount of movement of the support 6. A friction magnet 1 is attached to the sliding part of the lamp 5 with the column 6.
A plastic sheet is interposed between the friction magnet 13 and the support column 6 so that the friction magnet 13 attracts the support column 6. A friction magnet 13 is also attached to the part of the fixture 12 that slides on the column 6, and the friction magnet 13 directly attracts the column 6 to obtain a larger frictional force than the part that slides on the lamp 5. It is now possible to

The operating tool 7 is an operating button 7 provided on the curtain plate 2a of the shelf 2.
a, an operating shaft 15 that protrudes from the back side of the operating button 7a and has a fixing magnet 14 at its tip, and urges the operating button 7a toward the front of the shelf 2 so that the front surface of the operating button 7a protrudes toward the front of the shelf 2. It is composed of a return spring 16 made of a coil spring, and a support 17 that is attached to the lower surface of the shelf 2 and supports the vicinity of the tip of the operating shaft 15.

An adherend 18 made of a steel plate is protruded from the upper surface of the lamp 5, and a fixing magnet 14 attached to the tip of the operating tool 7
This prevents the lamp 5 from moving. This adherend 18 comes into contact with the back surface of the curtain plate 2a when the lamp 5 is pulled out, and functions as a stopper to prevent the lamp 5 from protruding forward any further.

A pull-out spring 19 made of a coil spring is attached at both ends to the back side of the curtain plate 2a of the shelf 2 and the middle part of the support column 6. The pull-out spring 19 is always in a pulled state and urges the lamp 5 forward of the shelf 2, and when the lamp 5 is pulled out, it moves forward against the frictional force of the friction magnet 13. The spring constant is adjusted so that the adherend 18 is kept in contact with the back surface of the curtain plate 2a when the lamp 5 is moved, and when the lamp 5 is stored, the lamp 5 is maintained in the stored state by the attraction force of the fixing magnet 14. It is set.

Next, the operation of this undershelf lighting fixture will be explained.

When pulling out the undershelf lighting fixture 3 to the front of the shelf 2, first push in the operating button 7a of the operating tool 7, and the fixing magnet 14 attached to the tip of the operating shaft 15 of the operating tool 7 will move to the back of the shelf. The adherend 18 that was attracted to the fixing magnet 14 is removed from the fixing magnet 14.

Then, the frictional force of the sliding part between the column 6 and the lamp 5 is applied to the column 6.
This is smaller than the frictional force of the sliding part between the lamp 5 and the fixture 12, and the deviation between the center of gravity of the lamp 5 and the lamp rotation axis 8 is larger than the deviation between the center of gravity of the lamp 5 and the support rotating wheel 10. The lamp 5 rotates around the lamp rotating shaft 8 in an attempt to enter a stable state, and the stopper pin 5a is restricted from rotating by the lamp rotation regulating groove 9, with the front end in a lowered state.

Next, the support 6 is pulled forward by the pull-out spring 19 against the frictional force of the sliding portion with the fixture 12, and the stopper pin 12a of the fixture 12 is restricted from rotating in the support rotation regulating groove 11 and attached. When the body 18 comes into contact with the curtain plate 2a,
The lamp 5 is brought out.

When storing the lamp 5, when the lamp 5 is pushed into the shelf 2, the adherend 1 is attracted to the fixing magnet 14, and the lamp 5 is placed in a stored state.

Note that the pull-out spring 19 can also be omitted.

〔Effect of the invention〕

Since the present invention is configured as described above, the undershelf lighting device can be easily pulled out when in use, and has good operability when stored.
