Description

  The present invention relates to a lighting fixture and a lighting fixture cover.

In lighting fixtures, the design of covers such as shades and gloves that cover the light source is important. As a lighting device that is suspended from the ceiling, a device that has a spherical shape as a whole (see, for example, Patent Document 1) is known, but the shape itself has a design feature. A cylindrical or star-shaped cover in which a plurality of pyramids protrude in two directions or radially can be considered.
JP 2002-25319 A

  In the case of a cover with a complicated shape such as a star shape, unlike a lantern with a spiral shape with bamboo paper stuck to Japanese paper, it is difficult to fold, so when displaying in stores or stocking in warehouses etc. In addition to requiring a large space, there is a problem that it is inconvenient due to its size and shape when carrying and transporting.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a cover for a lighting fixture that can be made into a non-bulky form as described above, and can be reassembled into various forms by taking advantage of its ease of disassembly and assembly. And

As means for achieving the above object, the invention of claim 1 is characterized in that a light source is accommodated in a star-shaped or cylindrical cover in which a plurality of pyramid portions project radially.
The cover is configured in a shape in which the pyramid portion protrudes in a star shape or a cylindrical shape by joining a plurality of translucent patterns, and the pattern is a substantially triangular shape having the same shape and the same size. The two are composed of rhombuses that are formed by sharing their bases at line-symmetric positions, and the pyramids are formed by combining the corresponding hypotenuses of the substantially triangular portions of the two pattern papers, and the combination of the pyramids Therefore, it can be reassembled into various forms.

  According to a second aspect of the present invention, in the first aspect of the invention, a slit hole is formed on one oblique side of the substantially triangular portion, and the other oblique side of the substantially triangular portion corresponds to the slit hole. A connecting piece is formed to project, and the oblique sides are connected by inserting the connecting piece into the slit hole, and the connecting piece is smaller in size than the connecting piece. When a semicircular cut is formed in a direction opposite to that of the above-described form and the force moves in a direction in which the coupling piece falls out of the slit hole, a semicircular protrusion formed by the semicircular cut hits the slit hole. It has a feature in that it has an effect of strengthening the connection between the hypotenuses by having the role of preventing the falling off.

  According to a third aspect of the present invention, a lighting fixture is formed by forming a star shape in which a plurality of pyramid portions project radially, and a light source is accommodated therein, and a plurality of patterns having translucency are provided. By combining, it is configured in a substantially spherical form or a form in which a plurality of forms are joined together, and a form on a cylinder, and the corresponding hypotenuses of the substantially triangular parts of the two pattern papers are combined. It is characterized in that the pyramid portion is configured by being combined, and the polyhedron and the tubular form are configured by combining a plurality of the pyramid portions.

According to a fourth aspect of the present invention, in the third aspect, a slit hole is formed on one oblique side of the triangular portion, and a coupling corresponding to the slit hole is formed on the other oblique side of the triangular portion. A piece is formed to project, and the oblique sides are joined by inserting the joining piece into the slit hole,
In the coupling piece, a semicircular cut is made in a direction opposite to the shape of the coupling piece, which is smaller than the coupling piece, and when the force moves in a direction in which the coupling piece falls out of the slit hole, the semicircular shape The semicircular protrusion formed by the notch hits the slit hole and prevents it from falling off, thereby having the effect of strengthening the connection between the oblique sides.

<Invention of Claims 1 and 3>
Since the star-shaped cover is configured by joining a plurality of paper patterns, it can be kept thin and not bulky by horizontally stacking the paper patterns before joining. Therefore, the space for display and storage is small, and it is convenient to carry and transport.

<Invention of Claims 2 and 4>
The connection between the hypotenuses is a structure that can be easily combined and disassembled by inserting a coupling piece into the slit hole, but since the entire connection is made by the connection between the hypotenuses, it is important that the connection is firm. It is a feature of the present invention that a solid form of bonding is made by adding a “modulation effect”.

An object of the present invention is to provide a cover for a lighting fixture that can be reassembled into various forms by taking advantage of the ease of disassembly and assembly.

Embodiment 1

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to FIGS.

  In the lighting fixture of the present embodiment, a light bulb 19 is attached to a socket 18 inside a cover 10 having a star shape (compact-tow shape) in which 12 regular pentagonal pyramids (hereinafter referred to as pyramid portions 12) project radially. The light source 15 having the form is accommodated and can be used by being suspended from a ceiling or the like. The cover 10 is a regular dodecahedron (hereinafter referred to as a polyhedron 11) having a substantially spherical shape by combining 30 patterns 20 having the same shape and size (there is only one sheet having many cuts). It is comprised in the form which made the pyramid part 12 protrude from.

  The pattern paper 20 has a translucent milky white (that is, translucent) plate shape, is not easily broken or bent, and is made of a material having a relatively high heat resistance temperature. As the material of the pattern 20, flameproof paper / Warlon paper (Japanese paper with a resin layered or Japanese paper coated with a resin), a synthetic resin material containing no Japanese paper, or the like can be used.

  As shown in FIG. 3, the paper pattern 20 has a rhombus parallelogram composed of two projecting portions 22 (the two are 22a1 and 22a2) that form an isosceles triangle. The straight bases of the two protrusions 22a1 and 22a2 are shared, and the two straight oblique sides 24 and 25 of the protrusions 22a1 and 22a2 have the same length.

  Of the two oblique sides 24, 25 of each projecting piece portion 22, a strip portion 27 extending along the oblique side 24 is formed to be flush with the projecting piece portion 22. Four slit holes 28 are formed in the boundary line (slope side 24) between the band portion 27 and the projecting piece portion 22. The slit holes 28 extend in the longitudinal direction of the oblique side 24 and penetrate the pattern paper 20 from the front and back, and are arranged in series at a constant pitch in the longitudinal direction of the oblique side 24. The arrangement positions of the slit holes 28 are arranged so as to be symmetrical with respect to the left and right when a line perpendicular to the hypotenuse 24 is drawn at the center of the hypotenuse 24.

  The pattern paper 21 is obtained by adding a light bulb mounting frame 30 and its cut 32 and a cut 33 of a mounting hole 31 to the pattern 20. Before use, both of them have several uncut portions of 0.5 mm or less for connection at each of the cuts, and can be easily pushed by a finger during use.

  On the other hand, four coupling pieces 29 are formed on the oblique side 25 opposite to the side where the slit hole 28 is formed, of the two oblique sides 24 and 25 of each projecting piece portion 22. The coupling piece 29 has a shape in which a part of a perfect circle is notched in a comb shape (bow shape), and a straight line portion corresponding to the string is matched with the hypotenuse 25 and is flush with the protruding piece portion 22. It protrudes so as to be connected. The four coupling pieces 29 are arranged at the same pitch as the slit holes 28 in the length direction of the hypotenuse 25. The maximum outer diameter of the coupling piece 29 is 9 mm, which is slightly larger than the slit hole 28 length of 8 mm, and there is a slight resistance when the coupling piece 29 is inserted into the slit hole 28, but it is inserted. After that, it is stabilized by being accommodated in the narrowed slit hole 28, and conversely, the coupling piece 29 is made difficult to come off from the slit hole 28.

  In addition to the above-mentioned 0021, the coupling part has a small semi-circular notch 34 (diameter 4 mm in diameter) in the coupling piece for the purpose of stabilizing the form after assembling the star-shaped lighting cover, for the effect of “fishing hook”. The small semicircular moist portion 34 is bent in the middle (downward) side before joining, so that even if it enters the slit hole 28 as it is, it goes out to the belt portion 27 if it goes out. 39 is caught and plays a role of preventing the coupling piece 29 from being detached from the slit hole 28.

  Next, the assembly procedure of the lighting fixture of this embodiment is demonstrated.

  In this luminaire cover, a pyramid portion projecting radially from the center of the star luminaire cover is formed by combining a plurality of patterns 20, and the pyramid portions are connected to complete the substantially spherical star luminaire cover 10 as a whole. It is. Next, the details of the assembling procedure will be described with reference to an example of a star-shaped dodecahedron luminaire cover composed of 12 pyramids each having a regular dodecahedron surface on the bottom. The pattern used here is 30 maki.

  First, another pattern 20 (hereinafter referred to as second pattern 22b) is joined to the pattern 20 (hereinafter referred to as first pattern 22a). As a work before joining, all the band portions 27 and the joining pieces 29 of the pattern paper are bent in one direction. Further, the modding portion 34 cut into the coupling piece 29 is bent in the same direction as the band portion 27 and the coupling piece 29.

  Next, as shown in the figure, the paper patterns 22a and 22b are brought close to each other, and the coupling piece 29 is inserted into the slit holes 28 facing each other. At this time, it matches some resistance, but inserts it as it is. This is performed at the four slit holes 28 and the coupling piece 29 to bond the pattern paper 22a and the pattern paper 22b.

  The pattern paper 22b and the pattern paper 22c, the pattern paper 22c and the pattern paper 22d, the pattern paper 22d and the pattern paper 22e are combined, and finally the pattern paper 22e and the pattern paper 22a are combined. 12A is possible.

  When the five projecting piece portions constituting the pyramid portion 12 are 22a1, 22b1, 22c1, 22d1, and 22e1, the other projecting piece portions 22a2, 22b2, 22c2, 22d2, and 22e2 of the respective pattern papers are surrounded around them. Yes. Then, an arbitrary protruding piece portion is selected from the five protruding piece portions 22. Assuming that the arbitrary protruding piece 22a2 is 22a2, a new pattern 20f other than the above five patterns 20 is prepared for the protruding piece 22a2, and 22a2 and 22f1 are joined as before. Similarly to this connection, 22f1, 22g1, 22g1, 22h1, 22h1, 22i1, and 22i1 and 22a2 are connected to form the second pyramid portion 12B.

Similarly, the remaining pattern papers are joined to 22b2, 22c2, 22d2, and 22e2 to form four pyramid portions, and the remaining six pyramid portions are formed to make a total of 12 pyramid portions and a substantially spherical star luminaire. The form of the cover 10 is completed. The configuration numbers of the respective patterns of the 12 pyramid portions are as follows.
(1) 22a1, 22b1, 22c1, 22d1, 22e1
(2) 222, 22f1, 22g1, 22h1, 22i1
(3) 22b2, 22i2, 22j1, 22k1, 22l1,
(4) 22c2, 22l2, 22m1, 22n1, 22o1
(5) 22d2, 22o2, 22p1, 22q1, 22r1
(6) 22e2, 22r2, 22s1, 22t1, 22u1
(7) 22g2, 22t2, 22u1, 22v1, 22w1
(8) 22j2, 22h2, 22w2, 22x1, 22y1
(9) 22k2, 22y2, 22z1, 22A1, 22m2
(10) 22n2, 22A2, 22B1, 22C1, 22P2
(11) 22q2, 22C2, 23D1, 22u2, 22s2
(12) 22v2, 23D2, 22B2, 22z2, 22x2

    Before all of the above coupling is completed, the pattern paper 23 is finally coupled. A light source 15 is attached to the pattern paper. The light source 15 includes an outlet plug 16, a power cord 17, a socket 18 and a light bulb 19. The protrusion 23D1 of the pattern 23 has the same form as the two protrusions 21 and 22 of the pattern 20, but the protrusion 23D2 is provided with a cut hole 31 into which the cap portion 19A of the light bulb 19 is inserted. Further, there is a notch 32 of the light bulb support frame 30 around the hole so that the light bulb 19 is positioned at the center of the luminaire cover 10. First, the incision 32 of the light bulb support frame 30 is strongly pushed and broken inside with a finger (folding direction of the belt portion 27 and the coupling piece 29), the support frame 30 is bent at a right angle with respect to the pattern 23, and the light bulb is inserted at the center. The base 19A of the light bulb 19 is strongly pressed against the notch 33 of the hole 31 from the inside (bottom) side of the pattern 23, broken, drilled, inserted into this, and socketed to the base 19A protruding upward from the light bulb insertion hole 31 18, and light bulb 19 is screwed into socket 18. As a result, the light bulb 19 and the socket 18 are pressed and fixed to the light bulb support frame 30 of the pattern 23 from above and below.

  Since the light bulb 19 and the socket 18 are fixed to the pattern paper 23, the pattern paper 23 is joined to the remaining part of the lighting fixture cover 10 that has been assembled so far with the light bulb 19 in the inside. At this time, the electric wire cord 17 coming out of the socket 18 comes out to the outside from the apex of the pyramid part 12 which the projecting piece part 23D2 constitutes.
