Description

  The present invention relates to a lighting facility including a lighting duct.

  In order to partition an exhibition area or display exhibits in an exhibition, a partition composed of a prefabricated framework and panels may be used. As a partition used in offices and exhibitions, for example, a plurality of support columns are set up vertically from the floor, and a rectangular panel that is also set up vertically from the floor is sandwiched by the support columns, along the upper side of the panel. One that spans a long beam-like member called a beam between beams is known (for example, see Patent Document 1).

  Since the structure of the exhibition hall and the exhibition area is not constant, it is necessary to appropriately install lighting equipment according to the structure of the partitioned exhibition area. As a method of constructing a lighting facility in a partition, for example, a method of clipping a lighting fixture (light) to a beam or a method of attaching a lighting fixture having a special mounting structure to a dedicated beam (for example, , See Patent Document 2).

  However, if lighting equipment having no versatility as in the prior art is used, the lighting effects that can be used are limited because the usable lighting fixtures are limited. Furthermore, the lower the versatility, the easier the parts such as cables are to be disposable, which increases waste and is not good for the environment.

  For example, there is a lighting duct as a highly versatile lighting facility that is not used in the exhibition hall (see Patent Document 3). The lighting duct is long and has a U-shaped cross section orthogonal to the longitudinal direction, and has a structure in which a pair of linear conductors for supplying power are arranged in parallel along the longitudinal direction. When a lighting duct is used, it is possible to install a lighting fixture at an arbitrary position in the longitudinal direction, and the lighting fixture can be easily attached and detached.

  However, since the lighting duct is originally assumed to be fixed to the ceiling or wall, it cannot be easily attached to the beam. In general, lighting ducts cannot be mounted downward in an exhibition area without a ceiling.

  An object of the present invention is to provide a highly versatile lighting facility that can be flexibly applied to a partition.

  The lighting equipment of the present invention is open to the first beam outer surface and the first beam outer surface that are both parallel to the first direction and orthogonal to each other, and extends in the first direction. And a lighting duct and a relay member.

  The lighting duct has a duct body and a duct hook. The duct body illuminates from a long accommodating space along the second direction, a linear conductor accommodated in the accommodating space and extending in the second direction, and a direction substantially orthogonal to the second direction. An opening formed along the second direction so that a part of the fixture can be inserted into the housing space and the terminal of the lighting fixture can be brought into contact with the conductor from the outside, and both are parallel to the second direction and orthogonal to each other A first duct outer surface and a second duct outer surface, and a locking hole communicating from the second duct outer surface to the accommodation space. The duct hook extends from the first extending portion extending from the first duct outer surface in parallel with the first duct outer surface, and from the first extending portion to be parallel to the second duct outer surface. And a second extended portion that is extended.

  The relay member has an arm and an arm hook. The arm includes a main shaft portion having a contact surface facing the third direction, an auxiliary portion extending from the main shaft portion in the third direction, and a third portion from the main shaft portion between the contact surface and the auxiliary portion. And a screw having a pressing surface formed of an elastic member at an end portion in the third direction and a screw penetrating the main shaft portion in the third direction between the contact surface and the protruding portion. A bolt having a hole and an axis along the third direction and a head having a radius along the plane perpendicular to the third direction greater than the axis. The arm hook is parallel to a plane orthogonal to the third direction and extends from the main shaft portion and extends from the third extension portion in the third direction. A fourth extending portion.

  The lighting equipment is configured such that the second duct outer surface is in contact with the second beam outer surface when the second extending portion is inserted into the insertion space. Further, the auxiliary portion is configured to come into contact with the second beam outer surface when the fourth extending portion is inserted into the insertion space. Further, the contact surface is in contact with the second extending portion and the pressing surface is in contact with the outer surface of the second duct, the head is located in the accommodation space, and the bolt shaft is The lighting duct is configured to be fixed to the relay member by tightening the bolt in the state of being inserted into the locking hole.

  It is possible to take the first mode in which the lighting duct is directly attached to the beam-like member by inserting the duct hook into the insertion space. Furthermore, it is possible to adopt the second mode by attaching the lighting duct to the relay member in a state where the arm hook is inserted into the insertion space and the relay member is attached to the beam. By selecting the first mode and the second mode, the direction in which the duct opening of the lighting duct faces can be made different. Therefore, it becomes easy to select the direction in which the duct opening of the lighting duct faces even without a member such as a ceiling. Furthermore, since the direction in which the duct opening faces can be selected using one type of lighting duct, the configuration of the lighting equipment can be simplified. Also, by using a highly versatile lighting duct, it is possible to make the lighting equipment easier to use compared to the case where a lighting fixture is directly attached to the beam.

  As described above, according to the lighting equipment of the present invention, a highly versatile lighting equipment can be flexibly applied to a partition.

The longitudinal direction of the beam 12 may be along a direction other than horizontal as long as it can be attached in a direction intersecting with the longitudinal direction of the pole 10.

  FIG. 2 is a cross-sectional view taken along the line AA of the beam 12 shown in FIG. 1 and shows a cross section along a plane perpendicular to the longitudinal direction of the beam 12. A cross section along a plane perpendicular to the longitudinal direction of the beam 12 forms a constant cross section as shown in FIG. 2 everywhere in the longitudinal direction. In order to explain the configuration of the beam 12, the right direction along the plane of FIG. 2 is defined as the positive direction of x, the back direction perpendicular to the plane of the plane is defined as the positive direction of y, and the upward direction along the plane of the sheet is defined as the positive direction of z. . Further, the positive direction and the reverse direction are referred to as the negative direction. The longitudinal direction of the beam 12 coincides with the y direction.

Further, the beam 12 has a beam upper surface 32 on a plane facing the positive direction of z and orthogonal to the z direction, and a beam lower surface 33 on a plane facing the negative direction of z and orthogonal to the z direction. .

  Inside the beam 12, an upper insertion space 34 is formed near the beam upper surface 32. An upper opening 35 connected to the upper insertion space 34 is formed at the center of the beam upper surface 32 in the x direction. The width in the x direction from the beam surface 30 to the upper opening 35 on the beam upper surface 32 is formed to have the same value d as the width in the x direction from the beam back surface 31 to the upper opening 35.

  Furthermore, a lower insertion space 36 is formed in the vicinity of the beam lower surface 33 inside the beam 12. A lower opening 37 connected to the lower insertion space 36 is formed at the center of the beam lower surface 33 in the x direction. The width in the x direction from the beam surface 30 to the lower opening 37 on the beam lower surface 33 is formed to have the same value d as the width in the x direction from the beam back surface 31 to the lower opening 37.

  The width in the x direction of the upper opening 35 and the lower opening 37 is formed so that the panel 11 can be inserted. When the beam 12 is installed above the panel 11, the upper end of the panel 11 is inserted into the lower insertion space 36 from the lower opening 37. When the beam 12 is installed below the panel 11, the lower end of the panel 11 is inserted into the upper insertion space 34 from the upper opening 35. The beam 12 has a contrasting structure in each of the x direction, the y direction, and the z direction.

(Configuration of lighting equipment)
Next, the configuration of the lighting equipment 1 shown in FIG. 1 will be outlined. The lighting equipment 1 includes a lighting duct 13, a relay member 14, and a lighting fixture 15. Although not shown, the lighting equipment 1 includes a power cord that supplies power to the lighting duct 13 and a connection cord that electrically connects the lighting ducts 13.

(Configuration of lighting duct)
FIG. 3 is a front view of the lighting duct 13. In order to explain the configuration of the lighting duct 13, the front direction perpendicular to the paper surface of FIG. 3 is defined as the positive direction x, the right direction along the paper surface is defined as the positive y direction, and the upward direction along the paper surface is defined as the positive z direction. To do. The lighting duct 13 has a long, substantially rectangular parallelepiped shape, and the longitudinal direction coincides with the y direction. 4 is a cross-sectional view of the lighting duct 13 of FIG. 3 taken along the line BB. The cross section along the plane perpendicular to the longitudinal direction of the lighting duct 13 shown in FIG. 4 has the same shape everywhere in the longitudinal direction except for the locking holes 56.

  As shown in FIG. 4, the lighting duct 13 includes a duct body 40 and a duct hook 41.

  The duct body 40 has a planar duct surface 50 facing the positive direction of x and orthogonal to the x direction, a planar duct back surface 51 facing the negative direction of x and orthogonal to the x direction, and a positive direction of z. A planar duct upper surface 52 facing the z direction and facing the z direction, and a planar duct lower surface 53 facing the z direction and orthogonal to the z direction.

  Further, the duct main body 40 has a housing space 54 surrounded by a duct surface 50, a duct back surface 51, a duct upper surface 52 and a duct lower surface 53. A duct opening 55 penetrating the accommodation space 54 is formed on the duct surface 50. The duct opening 55 continues in a straight line along the y direction. Two engagement holes 56 penetrating the accommodation space 54 are formed in the duct back surface 51. The two locking holes 56 have the same shape and are shifted in the y direction. The width in the y direction of each locking hole 56 is larger than the width in the z direction. The width of the locking hole 56 in the z direction is constant except for the central portion in the y direction, and is formed to be slightly larger only in the central portion in the y direction.

  A linear conductor 58 held by a long insulating member 57 on the positive z side is disposed in the housing space 54 along the y direction, and held by the long insulating member 57 on the negative z side. The linear conductors 58 are disposed along the y direction. The lighting fixture 15 of FIG. 1 can be inserted with an electrode terminal from the duct opening 55 of the lighting duct 13 at an arbitrary position in the y direction shown in FIG. 4, and the electrode terminal is in contact with the linear conductor 58. The main body 40 can be fixed. Electric power is supplied to the linear conductor 58 from a power supply line (not shown).

  The duct hook 41 has an L-shaped cross section, and has a substantially rectangular first plate portion 60 extending from the duct upper surface 52 in the negative x direction, and a first plate portion 60 in the negative x direction. And a second plate portion 61 having a substantially rectangular shape extending downward from the most end portion. The second plate portion 61 is substantially parallel to the duct back surface 51, and the distance between the second plate portion 61 and the duct back surface 51 in the x direction is formed to be the same as or slightly larger than d. The duct hook 41 is fixed to the duct body 40 by screwing the first plate portion 60 to the duct upper surface 52 and adhering it with an adhesive.

  The linear conductor 58 is made of a material having high conductivity such as copper, and the insulating member 57 is made of a material having low conductivity such as rubber. Parts of the lighting duct 13 other than the linear conductor 58 and the insulating member 57 are formed of a material that is not easily deformed, such as aluminum.

  Note that the directions used to describe the configuration of the lighting duct 13 are used for convenience to describe the relative positional relationship of the components of the lighting duct 13. That is, if the relative positional relationship between the components in the lighting duct 13 is the same, the orientation of the entire lighting duct 13 can be changed as appropriate.

(Lighting duct installation example)
5 is a cross-sectional view of the beam 12 and the lighting duct 13 shown in FIG. FIG. 5 shows an example in which the lighting duct 13 is mounted sideways. That is, the normal direction of the duct surface 50 of the lighting duct 13 coincides with the front-rear direction. In FIG. 5, two lighting ducts 13 are attached to one beam 12, one lighting duct 13 is attached to the front side of the beam 12, and the other lighting duct 13 is attached to the rear side of the beam 12. .

  The lighting duct 13 attached in front of the beam 12 is attached in a state where the second plate portion 61 is inserted into the upper insertion space 34 from the upper opening 35 while the duct opening 55 faces the front. On the other hand, the lighting duct 13 attached to the rear of the beam 12 is attached in a state where the second plate portion 61 is inserted into the upper insertion space 34 from the upper opening 35 with the duct opening 55 facing the rear. .

  The lighting duct 13 can be attached simply by hooking the duct hook 41 on the beam 12, and the construction can be performed very easily because the duct hook 41 can be removed simply by moving the duct hook 41 upward. Further, since the distance between the second plate portion 61 and the duct back surface 51 is substantially the same as or slightly larger than the distance d between the beam surface 30 and the upper opening 35, the duct back surface 51 is in close contact with or close to the beam surface 30. To do. Therefore, the lighting duct 13 is difficult to tilt and the posture is stabilized. Furthermore, since one lighting duct 13 can be attached to the front and rear of the beam 12 in the same procedure, the construction is easy.

(Configuration of relay member)
FIG. 6 is a perspective view of the relay member 14 that connects the beam 12 and the lighting duct 13 shown in FIG. 1. FIG. 7 is a side view of the relay member 14. In order to explain the configuration of the relay member 14, in FIG. 7, the right direction along the paper plane is defined as the positive x direction, the back direction perpendicular to the paper plane is defined as the positive y direction, and the upward direction along the paper plane is defined as the positive z direction. To do. As shown in FIG. 6, the relay member 14 includes an arm 70, an arm hook 71, and a bolt 72.

  As shown in FIG. 7, the arm 70 is formed by bending a long strip-shaped aluminum, and includes a main shaft portion 80 that is long in the x direction and an end portion of the main shaft portion 80 in the negative x direction. and an auxiliary portion 81 extending in the negative direction of z. The main shaft portion 80 has a planar main shaft lower surface 82 that faces the negative direction of z and is orthogonal to the z direction, and a planar main shaft upper surface 83 that faces the positive direction of z and is orthogonal to the z direction. Of the main shaft lower surface 82, the vicinity of the leading edge in the positive direction of x is referred to as a contact surface 88. Between the auxiliary portion 81 and the contact surface 88, a projecting portion 84 having a rectangular parallelepiped shape projects from the lower surface 82 of the main shaft in the negative z direction. The projecting portion 84 is made of an elastic rubber material. A flat pressing surface 85 that faces the negative z direction and is orthogonal to the z direction is formed at the end of the protruding portion 84 in the negative z direction. The main shaft portion 80 is formed with a screw hole 86 penetrating in the z direction between the projecting portion 84 and the contact surface 88. The screw hole 86 can be fitted so that a bolt 72 having a shaft extending in the positive z direction from the head is moved in the z direction. A nut that matches the thread of the shaft is fixed in the positive direction of z so as to contact the screw hole 86. The radius of the head of the bolt 72 along the plane orthogonal to the z direction is larger than the radius of the axis of the bolt 72 along the plane orthogonal to the z direction. The auxiliary portion 81 has a flat auxiliary surface 87 that faces the negative direction of x and is orthogonal to the x direction.

  As shown in FIG. 7, the arm hook 71 formed of an aluminum material has a plate-like third plate portion 90 that is long in the y direction and extends in parallel to the main shaft upper surface 83, and a negative x direction. And a fourth plate portion 91 extending in the negative z direction from the endmost portion of the third plate portion 90, and is L-shaped when viewed in the y direction. The outermost end portion of the third plate portion 90 in the negative x direction has a linear shape along the y direction, and the fourth plate portion 91 is substantially parallel to the auxiliary surface 87. The distance between the fourth plate portion 91 and the auxiliary surface 87 in the x direction is formed to be the same as or slightly larger than d. The arm hook 71 is fixed by screwing the third plate portion 90 to the main shaft upper surface 83.

  Note that the directions used to describe the configuration of the relay member 14 are used for convenience to describe the relative positional relationship of the components of the relay member 14. That is, if the relative positional relationship of the components in the relay member 14 is the same, the orientation of the entire relay member 14 can be changed as appropriate.

(Installation example of relay member)
FIG. 8 is a DD cross-sectional view of the beam 12 and the lighting duct 13 shown in FIG. 1, and is a cross-sectional view of a cross section taken along a plane including the vertical direction and the front-rear direction from the left to the right. FIG. 8 is an example in which the lighting duct 13 is mounted downward by mediating the relay member 14. That is, the duct surface 50 of the lighting duct 13 faces the lower side in parallel with a plane perpendicular to the vertical direction. In the example of FIG. 1, four relay members 14 are attached to one beam 12, two relay members 14 are attached to the front side of the beam 12, and the other two relay members 14 are attached to the rear side of the beam 12. It is attached. Two relay members 14 hold one lighting duct 13.

  Each relay member 14 positioned on the front side of the beam 12 aligns the longitudinal direction of the arm hook 71 with the longitudinal direction of the beam 12, and the entire fourth plate portion 91 of the arm hook 71 extends from the upper opening 35 of the beam 12. It is attached in a state of being inserted into the upper insertion space 34. The longitudinal direction of the main shaft portion 80 of the arm 70 coincides with the front-rear direction, and the main shaft lower surface 82 faces the lower side in parallel with a plane orthogonal to the vertical direction.

  The relay member 14 can be attached simply by hooking the arm hook 71 on the beam 12, and the relay member 14 can be removed simply by moving the arm hook 71 upward, so that construction is extremely easy. Since the entire surface of the beam upper surface 32 is in contact with the third plate portion 90 of the arm hook 71 and the beam surface 30 is in close contact with or close to the auxiliary surface 87 of the arm 70, the relay member 14 is less likely to tilt and has a posture. stable. Since the arm hook 71 is formed long along the longitudinal direction of the beam 12, the relay member 14 is difficult to rotate around the main shaft portion 80.

  A lighting duct 13 is attached near the front end of the arm 70. The duct surface 50 faces downward in parallel with a plane perpendicular to the vertical direction. The longitudinal direction of the lighting duct 13 coincides with the longitudinal direction of the beam 12. The head of the bolt 72 is located in the accommodating space 54 of the lighting duct 13, and the shaft of the bolt 72 is inserted into the locking hole 56 of the lighting duct 13. As shown in FIG. 3, the locking hole 56 is widened in the center in the left-right direction. When the lighting duct 13 is moved to the left after the head of the bolt 72 is inserted into the receiving space 54 from the wide area located at the center of the locking hole 56, the bolt 72 is moved to the narrow area of the locking hole 56. It moves and the head of the bolt 72 cannot be removed from the locking hole 56 in the vertical direction. Further, the contact surface 88 is in surface contact with the second plate portion 61 from above, and the pressing surface 85 is in surface contact with the duct back surface 51. By tightening the bolt 72 in this state, the relay member 14 and the lighting duct 13 are firmly fixed.

  Since the relay member 14 and the lighting duct 13 are in contact with each other at two places in the front-rear direction across the bolt 72, it is possible to firmly fix compared to the case of only one place. Further, the relay member 14 and the lighting duct 13 can be made difficult to slip by the pressing surface 85 of the protruding portion 84 formed of an elastic member. Furthermore, the step in the vertical direction between the duct back surface 51 of the lighting duct 13 and the second plate portion 61 can be filled with the protruding portion 84 of the relay member 14, and the protruding portion 84 is arranged at the step. It is not necessary to prepare a separate storage space for the protruding portion 84 as a slip stopper, and the configuration is simplified.

  The lighting duct 13 of the present embodiment can be installed with the duct opening 55 oriented horizontally, and the duct opening 55 can be installed downward with the same configuration just by using the relay member 14. That is, compared with the case where the lighting duct 13 having a different structure is used depending on the direction in which the duct opening 55 is to be directed, the types of the lighting duct 13 can be reduced, so that the configuration is simple and the construction is easy. .

  The lighting equipment 1 of this embodiment can install the lighting duct 13 in the partition 2 and can select and arrange the direction in which the duct opening 55 faces. The lighting fixtures that can be directly attached to the partition 2 as in the past are limited, such as lighting fixtures with clips, and are often disposable together with wiring members connected to the lighting fixtures. On the other hand, since there are a relatively large number of lighting fixtures that can be attached to the lighting duct 13 and high versatility, according to the present embodiment, the number of disposable members is reduced and the environment is friendly.

  The present invention is not limited to the lighting equipment described above, and can be appropriately modified without departing from the spirit of the present invention.
