BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device mainly used as mood lighting in a coffee shop, a snack shop or the like.

[0002]

2. Description of the Related Art In a conventional general lighting fixture of this type, as shown in FIG. 7, for example, a pedestal 2 is fixedly mounted on a disk-shaped base 1 and is supported at the center of the pedestal 2. The pipe 3 is erected, and the socket 5 of the lamp 4 is mounted on the upper end of the support pipe 3. This socket 5 is a support pipe 3
It is electrically connected to the power cord line 6 via an inner wiring (not shown).

A cylindrical cover 7 having a diameter gradually increased toward the upper opening by a semi-translucent material having heat resistance is press-fitted into the pedestal 2 at the lower end opening, or a screw 8 after press-fitting. And is fixed to the pedestal 2. By covering the periphery of the lamp 4 with the cover 7, only the light emitted from the lamp 4 is directly irradiated upward, and the periphery is shielded by the cover 7 and only part of the light is transmitted. As a result, it is preferable lighting that enhances the mood in the store.

Although the above-mentioned conventional example describes a stand-type luminaire, the luminaire may be used as a ceiling light by hanging the support pipe 3 from the ceiling.

[0005]

By the way, when the above-mentioned lighting equipment is packaged for transportation, the cover 7 can be removed by loosening the screw 8, but a relatively thin cover 7 can be deformed. It is difficult to prevent them from being packed so as to be able to maintain a predetermined shape, and there is a problem that a bulky packing form is inevitable. Further, in the case where the lower end portion of the cover body 7 is simply inserted into the pedestal 2 without fixing with the screw 8, the cover body 7 is easily pulled out when the stand itself falls down, There is a drawback that inconveniences such as stain of the covering 7 and damage of the lamp 4 are likely to occur.

Therefore, the present invention provides a luminaire having a structure that can be disassembled so that it can be packed in a low volume, and that the cover can be easily attached and detached and the cover can be easily attached without being removed. Is a technical issue.

[0007]

According to the present invention, as a technical means for achieving the above-mentioned object, a lighting fixture is constructed as follows. That is, the invention of claim 1 is provided with a pedestal provided with a receiving hole whose inner diameter is gradually reduced toward one side in the axial direction, and through which the receiving hole is inserted to coincide with the axis of the receiving hole. A support pipe equipped with a lamp socket in a wired state at its tip, and a through hole that is frustoconical and is eccentric with respect to the axial center of the receiving hole is formed, and its outer diameter is One end of the weight, which is formed by gradually reducing the diameter toward one side in the axial direction corresponding to the inner peripheral surface of the pedestal, and bending the heat-resistant sheet in a substantially rectangular shape into the shape gradually reducing toward the one side in the axial direction. Is provided by being inserted into the receiving hole, and is sandwiched and fixed between the inner peripheral surface of the receiving hole and the outer peripheral surface of the weight.

According to the second aspect of the present invention, a base, a pedestal having a receiving hole which is fixed on the base and has an inner diameter which is gradually reduced toward the lower side, and an axial center of the receiving hole are formed. And a support pipe which is erected on the bottom surface of the receiving hole through the receiving hole and is equipped with a lamp socket at the upper end in a wired state, and the receiving pipe having an inverted truncated cone shape in the axial direction thereof. A through hole is formed that is eccentric to the axial center of the hole, and the outer diameter of the through hole is gradually reduced downward corresponding to the inner peripheral surface of the pedestal, and the through hole slides on the support pipe. A freely attached weight and a substantially rectangular heat-resistant sheet are bent downward to be gradually reduced in diameter, and the lower end thereof is provided by being inserted into the receiving hole. The cover is sandwiched and fixed to the outer peripheral surface of the weight.

Further, in the invention of claim 3, a support pipe which is hung from the ceiling and is equipped with a socket of a lamp in a wiring state is provided at a lower end portion, and a receiving hole which is formed so that the inner diameter thereof is gradually reduced and the diameter thereof is gradually reduced. And a pedestal slidably attached to the support pipe inserted through the receiving hole so as to coincide with the axial center of the receiving hole, and having a truncated cone shape in the axial direction with respect to the axial center of the receiving hole. A through hole that is eccentrically formed and has an outer diameter that gradually decreases toward the upper side in correspondence with the inner peripheral surface of the receiving hole, and a weight that is screwed into the support pipe, and a substantially rectangular shape.

[0010]

According to the invention of claim 1, the weight has a truncated cone shape, a through hole is formed in the axial direction of the weight so as to be eccentric with respect to the axis of the receiving hole, and the outer diameter of the through hole is the same. Since the weight is formed so as to gradually decrease in one axial direction in correspondence with the inner peripheral surface of the weight, when the weight is inserted into the receiving hole, the outer peripheral surface of the weight has the inner peripheral surface of the receiving hole on one surface thereof. And the action is further strengthened by the self-weight of the weight. Therefore, the one end of the cover inserted into the receiving hole is sandwiched between the inner peripheral surface of the receiving hole and the outer peripheral surface of the weight,
Further, the cover is strongly clamped on one surface of the outer peripheral surface of the weight, and the cover is fixed in the receiving hole. Further, when the weight is strongly inserted into the receiving hole, the weight is fitted into the receiving hole while slightly tilting the support pipe, and the restoring force of the support pipe causes the outer peripheral surface of the weight to interpose the covering body. Since it acts so as to be pressed against the inner peripheral surface of the receiving hole, the one end portion of the cover is more firmly clamped and fixed between the receiving hole and the weight. Further, since the covering body is made of a sheet having a substantially rectangular shape and flexibility before attachment or detachment,
In packaging, the covering body is wound several times to form a tubular shape having a small diameter, so that it can be made significantly low in volume while preventing deformation.

A through hole having a truncated cone shape and eccentric with respect to the axial center of the receiving hole is formed in the axial direction, and the outer diameter thereof is gradually reduced downward corresponding to the inner peripheral surface of the receiving table. Since the weight is formed into a diameter, when the weight is inserted into the receiving hole, the outer peripheral surface of the weight makes strong pressure contact with the inner peripheral surface of the receiving hole at one peripheral surface thereof, and the action is further strengthened by the weight of the weight. To be Therefore, the lower end portion of the covering body inserted into the receiving hole is sandwiched between the inner peripheral surface of the receiving hole and the outer peripheral surface of the weight, and strongly sandwiched between the outer peripheral surface of the weight and the covering body. Is fixed in the receiving hole, and the cover is not pulled out from the pedestal when the stand itself is tilted.

According to the third aspect of the present invention, a receiving hole is formed whose inner diameter is gradually reduced and the diameter is gradually reduced, and the receiving pipe is inserted into the receiving pipe so as to be aligned with the axis of the receiving hole. A pedestal that is movably attached and a through hole that has a truncated cone shape and is eccentric with respect to the axis of the receiving hole in the axial direction, and its outer diameter corresponds to the inner peripheral surface of the receiving hole. Since the through hole is formed to have a diameter gradually reduced upward and the through hole is composed of a weight screwed to the support pipe, when the weight is inserted into the receiving hole of the pedestal, the inner peripheral surface of the receiving hole is The action is further strengthened due to the strong pressure contact with the outer circumferential surface of the weight on one circumferential surface and the weight of the pedestal. Therefore, the upper end of the cover inserted into the receiving hole is sandwiched between the inner peripheral surface of the receiving hole and the outer peripheral surface of the weight, and strongly sandwiched on one surface of the outer peripheral surface of the weight. Is fixed in the receiving hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. Note that the same or corresponding portions as those in FIG. FIG. 1 shows an exploded perspective view of an embodiment of the present invention, in which a pedestal 9 is fixedly mounted on a disk-shaped base 1. The pedestal 9 is formed in a bottomed cylindrical shape having a substantially inverted truncated cone shape in which a receiving hole whose inner diameter is gradually reduced and whose diameter is gradually reduced is formed in the axial direction. Then, the support pipe 3 is erected on the bottom surface of the receiving hole 9A by inserting the receiving hole 9A in alignment with the axis of the receiving hole 9A of the receiving table 9. A socket 5 for the lamp 4 is mounted on the tip of the support pipe 3. This socket 5 is a support pipe 3
It is electrically connected to the power cord line 6 via an inner wiring (not shown). Reference numeral 10 denotes a weight, which is formed by a metal such as brass into an inverted truncated cone shape whose diameter is gradually reduced downward.
The outer diameter is formed so as to correspond to the inner surface of the receiving hole 9A so that it can be fitted into the receiving hole 9A. The weight 10 is formed with a through hole 10a having an axis Y that is eccentric with respect to the axis X of the receiving hole 9A in the axial direction thereof.
The weight 10 is attached to the support pipe 3 by slidably inserting the support pipe 3. In addition, a covering 11 made of a heat-resistant sheet having a substantially rectangular shape and semi-translucency is wound into a cylindrical shape having a diameter expanded toward the upper opening, and the lower end portion thereof is received in the receiving hole 9A of the receiving table 9. While being inserted, the lower end portion of the cover 11 is clamped and fixed between the outer peripheral surface of the weight 10 fitted into the receiving hole 9A of the receiving table 9 and the inner peripheral surface of the receiving hole 9A.

Therefore, as shown in FIGS. 3 and 4, the covering 11 made of a substantially rectangular sheet is wound into a cylindrical shape whose diameter is expanded toward the upper opening, and the corresponding fastening holes 11 are formed.
By matching a and inserting and attaching the stopper 12,
The covering body 11 is shaped so as to have a substantially inverted truncated cone shape with an outer diameter as shown in FIG.

When the weight 10 is slid on the support pipe 3 as shown by the solid line in FIG. 3 and is removed from the receiving hole 9A of the pedestal 9, the cover 11 having the above-described shape is formed.
The lower end portion of is inserted into the receiving hole 9A. At this time, when the cover 11 is inserted while rotating, the lower end insertion portion of the cover 11 into the receiving hole 9A is shaped into a shape that fits on the inner peripheral surface of the receiving hole 9A.

Subsequently, the weight 10 is slid on the support pipe 3 and is lowered to be fitted into the receiving hole 9A of the receiving base 9 as shown by the alternate long and short dash line in FIG. The lower end portion of the cover 11 is clamped and fixed between the surface and the outer peripheral surface of the weight 10. At this time, since the weight 10 is inserted in a slightly eccentric state with respect to the support pipe 3, when the weight 10 is inserted into the receiving hole 9A, the outer peripheral surface of the weight 10 has a receiving hole 9A on one surface thereof. Strongly pressure contact with the inner surface of the and weight 10
Its action is further strengthened by its own weight. Therefore,
The lower end of the cover 11 inserted into the receiving hole 9A is sandwiched between the inner peripheral surface of the receiving hole 9A and the outer peripheral surface of the weight 10 and strongly sandwiched on one outer peripheral surface of the weight 10. The cover 11 is fixed in the receiving hole 9A. Further, when the weight 10 is strongly inserted into the receiving hole 9A, the weight 10 is press-fitted into the receiving hole 9A while slightly tilting the supporting pipe 3, so that the supporting pipe 3
The outer peripheral surface of the weight 10 acts so as to be pressed against the inner peripheral surface of the receiving hole 9A with the covering body 11 interposed therebetween by the restoring force of 1. Therefore, the lower end portion of the covering body 11 is provided between the receiving hole 9A and the weight 10. Since it can be more firmly clamped and fixed, the weight 10 does not slip out from the receiving hole 9A when the stand itself is tilted and the stand itself is turned upside down. Therefore, the cover 11 is received in the receiving hole 9A of the pedestal 9. It can be retained without falling inside. still,
When it is desired to replace the cover 11, the weight of the weight 10 can be easily removed by removing the weight 10 from the inside of the receiving hole 9A by holding the stand itself upside down and applying an impact from the back surface of the base 1. The new cover 11 may be attached by the procedure described above.

Further, in the case of packing for transportation, a substantially rectangular covering 11 made of a flexible film is used.
By winding it several times to form a small-diameter cylindrical shape, it can be packaged in a significantly reduced bulk while preventing deformation.

FIG. 6 shows another embodiment of the present invention, in which the lighting device of the present invention is used as a ceiling light. In FIG. 6, the support pipe 3 is vertically installed from the ceiling, and the socket 5 of the lamp 4 is installed in a wiring state at the lower end portion. Unlike the above-described embodiment, the receiving table 9 is slidably attached to the support pipe 3 by inserting the receiving hole 9A into the support pipe 3. The receiving hole 9A is formed such that the inner diameter thereof is gradually reduced toward the upper side, and the receiving hole 9A is aligned with the axial center of the support pipe 3. The weight 10 has the shape of a truncated cone and has the receiving hole 9 in the axial direction thereof as in the case of the above embodiment.

0a is formed, and its outer diameter is gradually reduced upward in correspondence with the inner peripheral surface of the receiving hole 9A.
In the above-mentioned embodiment, the female screw 10a1 is provided in the through hole 10a and the support pipe 3 is engraved with a male screw so that the weight 10 and the support pipe 3 are screwed and the weight 10 is fixed to the support pipe 3. Different from the example. Since this embodiment of the present invention is a ceiling light, the covering 11 of the heat-resistant sheet having a substantially rectangular shape is bent in a shape in which the diameter is gradually reduced upward and its upper end is inserted into the receiving hole 9A. And is clamped and fixed between the inner peripheral surface of the receiving hole 9A and the outer peripheral surface of the weight 10.

The operation and effect of this embodiment are such that the weight 10 slidably slides on the support pipe 3 in the above-described embodiment, whereas the pedestal 9 slides on the support pipe 3 in this embodiment. By freely sliding the cover 11 to the receiving table 9
Is to be clamped between the inner peripheral surface of the receiving hole 9A and the outer peripheral surface of the weight 10, that is, the receiving hole 9 of the pedestal 9
Since the A and the weight 10 screwed to the support pipe 3 are eccentric, when the weight 10 is inserted into the receiving hole 9A of the pedestal 9, the inner peripheral surface of the receiving hole 9A has a weight 10 at its peripheral surface.
The action is further strengthened due to the strong pressure contact with the outer peripheral surface of and the weight of the pedestal 9. Therefore, the upper end of the cover 11 inserted into the receiving hole 9A is sandwiched between the inner peripheral surface of the receiving hole 9A and the outer peripheral surface of the weight 10, and the weight 1
It is strongly clamped on one surface of the outer peripheral surface of 0, and the covering body 11 is fixed in the receiving hole 9A. Other functions and effects are similar to those of the above embodiment.
