Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a hanging light that is suspended from the ceiling by a linear body such as a chain attached to an umbrella.

[Prior art]

As conventional hanging lights, those described in Japanese Utility Model Publication No. 32-10084 and Japanese Unexamined Patent Publication No. 52-70583 are known.

The one described in the former publication is a hanging light in which a ring is attached to a concentric circle centered on the center of gravity of a fluorescent lamp, and the lamp is suspended from a hanging device with a pulley attached to the end.

When the pulley moves along the circular arc surface of the ring and is positioned equidistant from both the left and right ends of the ring, it illuminates directly below, when the pulley is positioned to the right, it illuminates the right side, and when it is positioned to the left, it illuminates the left side. It is called irradiation.

The ring itself neither rotates nor moves in the longitudinal direction of the fluorescent lamp.

In this conventional example, it is not possible to adjust the interval between the two hanging fixtures or the attachment position to the fluorescent lamp, making it impossible to attach the fluorescent lamp depending on the location.

In other words, it lacks the flexibility of being able to install it anywhere.

Furthermore, although it is possible to change the irradiation direction freely, it lacks stability in a stationary position, and if a slight force is applied to the fluorescent lamp, the irradiation direction easily changes, making it difficult to use. be.

The latter conventional example (Japanese Unexamined Patent Publication No. 52-708583) describes a structure in which a cord is attached to a location apart from the center of a socket base, and a cord is attached to a cylindrical movable body having a circular brim. When the center of gravity of the lighting equipment body is eccentric from the center, the cord can be set so that it passes over the center of gravity by moving this movable body horizontally in accordance with this eccentricity, and as a result, the cord It is stated that the socket is located at a location spaced apart from the center of the socket base or the center of the lighting fixture body.

In this conventional example, even if the cord is a hanging device, . . . (chain, etc.), the attachment location cannot be freely selected, and furthermore, no measures have been taken to easily change the irradiation direction.

〔Mejiro Tsuki〕

This idea was devised in view of the above circumstances,
The hanging device, such as a chain, can be attached freely at any position in the longitudinal direction of the umbrella on the circumference having a desired diameter (the center is on the slidable area in the longitudinal direction), It is an object of the present invention to provide a hanging light which increases the degree of freedom in mounting location, allows easy adjustment of changes in irradiation direction, and is difficult to change after adjustment.

[Structure]

In order to achieve the above object, this invention provides a hanging lamp that is suspended by a linear body such as a chain attached to an umbrella that covers a fluorescent tube, in which a guide groove is formed along the longitudinal direction of the center of the umbrella. and at least two knobs are attached to the guide groove so as to be slidably and non-slipably restrained at a desired position, and these knobs themselves are rotatable in a slidable state with a center of rotation on the guide groove. The above-mentioned filamentous body is attached to a location apart from the center of rotation of these knobs, and the hanging position of the filamentous body is adjusted by sliding along the guide grooves of two or more knobs, and the hanging position of the filamentous body is adjusted. The direction of irradiation of the hanging lamp can be adjusted by removing the filament portion from the guide groove by rotation.

〔Example〕

Preferred embodiments of this invention will be described below based on the drawings.

FIG. 1 is a partially cutaway sectional view of a hanging light according to this invention, FIG. 2 is a perspective view of the whole, and FIG. 3 is an enlarged perspective view of a knob.

Inside the canopy 1, a mirror-finished reflector plate 3 having a parabolic cross section is attached at a position opposite to the irradiation opening 2, with one end thereof being locked to a protrusion 4 provided on the inner wall of the canopy 1. A fluorescent tube 5 is disposed approximately at the focal point of the reflecting plate 3 via a socket (not shown).

Further, the irradiation opening 2 is provided with a mounting member 7 having a substantially U-shaped cross section.
A looper 8 is fitted through the hole.

The looper 8 is not a thin plate 8a with a diamond-shaped cross section formed in a lattice shape, but is made of a heat-resistant and impact-resistant resin such as polystyrene, and the surface is coated with a highly reflective material such as aluminum. It is something that

In addition, a guide groove 9 is provided along the longitudinal direction in the center of the upper surface of the reel 1.
is provided in the guide groove 9, and a pot-like knob 10 is provided in the guide groove 9.
In the illustrated example, two are attached.

The knob 10 is attached to the guide groove 9 so as to be able to slide freely and to be restrained at appropriate locations in the groove, and is also configured to be rotatable when the knob 10 is released from the restraint. has been done.

To restrain the knob 10 at an appropriate location in the guide groove 9,
Hexagon socket head bolt 13 located at the rotation center of the knob 100
using a wrench or the like, and insert the restraining member (not shown in the symbol) screwed onto the hexagon socket head bolt 13 (the unhatched member located above the leader line 9 in FIG. 1) into the guide groove 9. position, and align the edge of the guide groove 9 with this member and the knob 10.
The knob 10 is held in the guide groove 9 by sandwiching the knob 10 between the guide grooves 9 and 9.

At this time, the knob 10 cannot be rotated.

Furthermore, a hook member 11 is fixed to a portion of the knob 10 that is spaced apart from the hexagon socket head bolt 13, and the base end of a chain 12, which is a filament for hanging, is attached to the hook member 11.

To explain the function of the hanging light of this invention constructed in this way, the hook member 11 attached to the knob 10
When the position is directly facing the guide groove 9, the irradiation opening 2 faces parallel to the horizontal irradiation surface, but if the knob 10 is rotated 90 degrees from the above position and restrained, the chain 12 Guide groove 9 in the center of the top surface of the base end of the umbrella 1
Since the irradiation aperture 2 is separated from the position of , the irradiation aperture 2 comes to have a predetermined angle with respect to the irradiation surface, and as a result, the irradiation direction changes (see FIG. 4).

Next, as shown in FIG. 5, when beams 16 are stretched across the ceiling 15 vertically and horizontally, and it is difficult to attach parts to the beams 16 or is not allowed from an aesthetic point of view, two knobs 10 are installed. It is necessary to change the relative position of

In other words, if the attachment position of the chain 12 to the fluorescent lamp shaft 1 is fixed, the beam 16 will get in the way as shown by the broken line in FIG. 5, spoiling the aesthetic appearance, or it will be necessary to find a new attachment location.

Therefore, if the position of the knob 10 is made freely movable so that the base end of the chain 12 can be attached as in this invention, the fluorescent lamp can be hung with the axial direction of the chain 12 aligned with the vertical direction. This makes it possible to easily avoid obstacles near the ceiling.

〔effect〕

As explained above, according to this invention, the angle of the irradiation aperture of the hanging light with respect to the irradiation surface can be changed arbitrarily, so it is useful when applied to a hanging light that can emit spot light. In a hanging light that is suspended by the attached filament, the irradiation angle can be changed arbitrarily by moving the attachment point of the filament, so it can be adapted to the installation location or preference. , spot irradiation is also possible.

In addition, even if there are obstacles such as beams near the ceiling, the hanging light can be hung by moving the mounting point of the striate body and placing the striate body in a position that avoids the obstacle. Can be installed without being affected by objects.

That is, the mounting location can be set freely, and unlike conventional products, it is unlikely that the mounting location cannot be set depending on the location.

For example, by gathering two or more knobs at the longitudinal center of the umbrella, it is possible to achieve the same effect as if they were suspended from a single filament, or conversely, by gathering all the knobs at one end of the umbrella, it is possible to achieve the same effect as if the knobs were suspended from a single filament. It can also be hung like a cantilever.

Such an example is effective when there is only a narrow area in which to attach the filament to the ceiling.

In addition, with this invention, linear sliding and rotation of the knob is performed while the knob is not restrained by the guide groove, and once the knob is restrained, sliding and rotation are impossible.
After changing the irradiation direction to a desired position, the positioning becomes reliable and the irradiation direction will not change easily even if force majeure is applied to the umbrella.
