The vertical direction is referred to as the vertical direction, and the longitudinal direction (predetermined display direction) of the rack plates is referred to as the horizontal direction. In order to avoid complication of the drawings, the drawings of the commercial products mounted on the shelf board are appropriately omitted.

In fig. 1 and 2, the display rack 1 includes: a base 2 of a substantially rectangular parallelepiped shape placed on a floor, 2 support columns 3, 4 fixed to the rear side of the base 2 and fixed to both sides in the left-right direction and extending in the vertical direction, an auxiliary support column 5 provided so as to straddle the upper end portions of the 2 support columns 3, 4, and a plurality of shelf plates 6 provided so as to straddle the middle portions of the 2 support columns 3, 4. An upper display plate 7 is provided upright above the auxiliary column 5 by a magnetic force of a bolt or a magnet.

A plurality of fixing holes 11 are formed at equal intervals in the vertical direction on the front side surface of each of the pillars 3 and 4. As shown in fig. 3 in which the side surfaces of the chassis 6 are enlarged, the fixing claws 12 fixed to the left and right ends of each chassis 6 are locked in the fixing holes 11 of the support columns 3 and 4, whereby each chassis 6 can be firmly fixed to the support columns 3 and 4. A commodity (a display material) S is placed on the upper surface of the shelf plate 6. The fixing claws 12 can be selectively locked in the fixing holes 11 of any height of the pillars 3 and 4, as long as the heights of both ends in the left-right direction of each frame plate 6 are equal. That is, each shelf 6 can be selectively set at its height position and set there.

The power supply rail main body 31 is formed in a substantially rectangular parallelepiped shape (long in a direction orthogonal to the plane of the paper in fig. 6) as a whole, and installation grooves 34, 35 are formed continuously along the longitudinal direction (the left-right longitudinal direction of the chassis 6; the predetermined display direction) on both side portions (both side portions in a direction orthogonal to the predetermined display direction) of the upper portion and the lower portion. The upper installation groove 34 formed in the upper portion has locking grooves 36 formed in the vicinity of the opening portion on both front and rear side surfaces thereof, a positive electrode supply electrode portion 37P provided at an intermediate position in the vertical direction on the rear side surface, and a negative electrode supply electrode portion 37M provided in the vicinity of the bottom of the groove on the front side surface. The 2 supply electrode portions 37P and 37M are each made of a conductive material such as a metal, and are continuously provided along the longitudinal direction (predetermined display direction) with substantially the same length as the power supply rail main body 31.

The lower installation groove 35 formed in the lower portion of the power feeding rail main body 31 is formed so that the inside thereof overlaps with the inside of the upper installation groove 34 in the vertical direction (depth direction), and the lower installation groove 35 is provided on the front side of the upper installation groove 34. The shape of the internal structure of the lower installation groove 35 and the arrangement of the supply electrode portions 37P and 37M are symmetrical to the shape and arrangement of the internal structure of the upper installation groove 34 in the front-rear direction and the vertical direction.

An installation locking claw 32a is formed at each of the upper end and the lower end of the rear side surface on which the guide rail 32 is installed. The decorative plate 33 and the installation rail 32 are each formed with 2 fitting grooves 38, and are attached to the power supply rail body 31 by fitting these fitting grooves 38 into fitting protrusions 39, 2 of which are formed on the front side surface and the rear side surface of the power supply rail body 31, respectively.

The illuminated display attachment 100 is composed of an illuminated insertion unit (illumination display) 41 and a card holder (display) 101. The card holder 101 includes a fixing portion 102, a bending portion 103, and a holder portion 104. The illuminated insert assembly 41 includes: 2 parts of the 1 st assembly part 42 and the 2 nd assembly part 43 which can be combined, and a lighting circuit 44 which is installed by being sandwiched between these parts.

The 1 st block member 42 is made of a light-transmitting resin material, and the 1 st cover portion 42a and the 1 st insertion portion 42b thereof are integrally formed. In addition, a fixing groove 42c into which the fixing portion 102 of the card holder 101 can be inserted and fixed is formed on one side in the front-rear direction of the 1 st lid portion 42 a. The 2 nd cover part 43a and the 2 nd insertion part 43b of the 2 nd module member 43 are integrally formed. The lighting circuit 44 includes: the LED module includes a substrate 45, 3 LEDs 46 arranged on one surface of the substrate 45, and 2 terminal portions 47 and 48 extended from both end portions of the other surface of the substrate 45.

Fig. 7 is an external view of the illuminated insert unit 41 in an assembled state, fig. 7(a) is a plan view, fig. 7(b) is a front view, and fig. 7(c) is a side sectional view taken along line VIIc-VIIc in fig. 7 (b). As shown in fig. 7, the 1 st cover part 42a and the 2 nd cover part 43a in the combined state form a hollow substantially rectangular parallelepiped module main body part 50, and the 1 st insertion part 42b and the 2 nd insertion part 43b in the combined state form a flat-plate module insertion part 51. The illuminated insertion unit 41 can be attached to the power supply rail 21 by inserting the unit insertion portion 51 into the installation grooves 34 and 35 of the power supply rail main body 31. Further, locking claws 52 protruding from the mutually opposite side surfaces are formed on the 1 st insertion portion 42b and the 2 nd insertion portion 43b, respectively, and when the module insertion portion 51 is inserted into the installation grooves 34, 35, these locking claws 52 are locked in the locking grooves 36 inside the installation grooves 34, 35, and the installation of the insertion module 41 with illumination is stabilized.

In the combined state, the substrate 45 of the lighting circuit 44 is disposed inside the module body 50, and the 3 LEDs 46 provided on the substrate 45 are disposed so as to be capable of emitting light in the direction opposite to the module insertion portion 51. The 2 terminal portions 47 and 48 extending from both ends in the longitudinal direction of the board 45 are respectively sandwiched between the 1 st insertion portion 42b and the 2 nd insertion portion 43b, and only the terminal protruding portions 47P and 48M formed at the ends of the terminal portions 47 and 48 protrude from the mutually opposite side surfaces of the module insertion portion 51.

The positive electrode terminal protrusion 47P is located at an intermediate position in the insertion direction of the module insertion portion 51, and the negative electrode terminal protrusion 48M is located near an end of the module insertion portion 51. Thus, by inserting the lighting insertion unit 41 into the installation grooves 34 and 35 of the power supply rail 21 in the correct front-rear direction, the 2 terminal protrusion portions 47P and 48M can be brought into contact with the 2 supply electrode portions 37P and 37M with the corresponding polarities, and can be electrically contacted (see fig. 11 described later). Then, 3 LEDs 46 are connected in parallel with the 2 terminal portions 47 and 48 in the forward polarity.

Further, as described above, since the shape of the internal structure of the lower installation groove 35 of the power supply rail main body 31 and the arrangement of the supply electrode portions 37P and 37M are symmetrical to each other with respect to the shape of the internal structure of the upper installation groove 34 and the arrangement of the supply electrode portions 37P and 37M in the front-rear direction and the vertical direction, the same insertion module 41 with illumination can be inserted into either one of the upper installation groove 34 and the lower installation groove 35, and the terminal portions 47 and 48 can be electrically brought into contact with the supply electrode portions 37P and 37M of the corresponding polarities (however, the orientation of the insertion module 41 with illumination when inserted into the installation grooves 34 and 35 is reversed in the front-rear direction and the vertical direction).

In fig. 11, the setting rail 32 is engaged with a holding rail 71 fixed to a front end of the frame plate 6, and the power supply rail 21 is provided. In this example, 2 gripping claws 72 formed at the upper end portion and the lower end portion of the gripping guide rail 71 engage and grip the 2 installation locking claws 32a of the installation guide rail 32 so as to sandwich them. When the plug 24 connected to the power feeding rail 21 is inserted into the relay linear socket 22 (neither of which is shown in fig. 11), electric power is supplied to the power supply electrode portions 37P and 37M in the power feeding rail main body 31, and the LED46 in the illuminated insert unit 41 is energized and lighted via the terminal portions 47 and 48 in contact with the power supply electrode portions 37P and 37M. The LED46 of the illuminated display unit attachment 100 irradiates the card holder 101 with illumination light, and the LED46 of the illuminated magnifier attachment 200 irradiates the space in the vicinity of the magnifier 201 with illumination light (the module main body portions 50 are made of a translucent material, and thus transmit the illumination light).

Further, by providing the bent portion 103 in the card holder 101 of the illuminated display unit attachment 100, the support portion 104 can be swung and deformed in the direction of the arrow shown in the figure. As a result, when the product S comes into contact with the card holder 101 when the product S is taken out as shown in fig. 12, the holder portion 104 is swung and deformed in accordance with the contact, and the product S can be taken out easily. Although not particularly shown, the magnifying glass attachment 200 with illumination is also provided with the similar bent portion 204, and thus even if the product S comes into contact with the lens portion 203, the lens portion 203 can be swung and deformed in accordance with this.

In the above, the power cord 27, the AC adapter 26, the trunk line 25, the trunk straight socket 22, the plug 24, the power supply line 23, and the power supply rail 21 constitute a power supply system.

As described above, according to the display shelf of the present embodiment, the display unit attachment 100 with illumination (or the magnifying glass attachment 200 with illumination) can be attached to the installation grooves 34 and 35 of the power supply rail 21 at an arbitrary position in the longitudinal direction (predetermined display direction) of the shelf plate 6, and further, power can be supplied to the LED46 of the display unit attachment 100 with illumination via the supply electrode portions 37P and 37M. The power feeding rail 21 is provided at the front end of the chassis 6, and includes the installation grooves 34 and 35 and the power feeding electrode portions 37P and 37M at both the upper and lower portions thereof, thereby enabling power feeding to both the upper and lower sides (two directions orthogonal to the predetermined display direction) of the installed chassis 6 with a high degree of freedom of arrangement. Further, even when the plurality of shelves 6 are provided at different intervals in the arrangement direction thereof, the plug 24 of the power supply rail 21 provided in each shelf 6 can be inserted into the insertion groove 61 of the relay linear socket 22 at the shortest position, that is, the power supply can be performed with a high degree of freedom of arrangement with respect to the installation position of each shelf 6.

In the present embodiment, in particular, since the 2 installation grooves 34 and 35 are formed repeatedly in the vertical direction (depth direction) thereof, the width dimension of the power feeding rail 21 (the dimension in the depth direction of the installation grooves 34 and 35) can be reduced to save space; further, by disposing the lower installation groove 35 further forward than the upper installation groove 34, the attachment installed in the lower installation groove 35 is not blocked by the shadow of the shelf plate 6, and almost the entire attachment can be displayed to the user M.

In the present embodiment, in particular, the internal structure of each of the 2 installation grooves 34, 35, i.e., the upper installation groove 34 and the lower installation groove 35, and the supply electrode portions 37P, 37M are formed in a shape and arrangement that are symmetrical with each other in the front-rear direction and the up-down direction (depth direction), so that the structure of the component insertion portion 51 (including the structure including the terminal portions 47, 48 that are in contact with the supply electrode portions 37P, 37M) that are inserted into the installation grooves 34, 35 can be shared by the accessory device attached to the upper installation groove 34 of the power supply rail 21 and the accessory device attached to the lower installation groove 35. That is, it is possible to share the parts of the illuminated insert unit 41 in both the accessories and to replace the upper side and the lower side of the same accessory (which are opposite to each other).

Further, each shelf 6 can be selectively provided at a plurality of positions in the arrangement direction, and thus the installation position of each shelf 6 can be freely set in the arrangement direction, so that even when the degree of freedom of the installation position of the shelf 6 is high, it is possible to perform power feeding with a high degree of freedom of arrangement by changing the insertion position of the plug 24 with respect to the relay linear socket 22 in accordance with the degree of freedom.

In the present embodiment, in particular, the illuminated display unit attachment 100 includes the card holder 101 for displaying the display to the user M and the illuminated insertion unit 41 for irradiating the card holder 101 with the illumination light by the power supplied from the supply electrode units 37P and 37M, and thereby the display on the card holder 101 can be clearly and conspicuously displayed to the user M.

In the present embodiment, the illuminated magnifier attachment 200 includes the magnifier 201 for magnifying and displaying the product S and the illuminated insert unit 41 for irradiating the space near the magnifier 201 with illumination light by the power supplied from the supply electrode units 37P and 37M, so that the user M can visually recognize the product S in detail only by placing the product S on the shelf plate 6 or by holding the product S slightly upward from the shelf plate 6 so as to be positioned on the rear side of the magnifier 201.

In the present embodiment, in particular, the illuminated display unit attachment 100 and the illuminated magnifier attachment 200 have the elastically deformable bent portions 103 and 204 in the vicinity of the respective illuminated insertion assemblies 41, so that even when the user M takes out the product S from the shelf plate 6, the product S contacts the card holder 101 or the magnifier 201, the card holder 101 or the magnifier 201 is easily bent at the bent portions 103 and 204, and the product S can be taken out smoothly.

The types of attachments attached to the power supply rail 21 are not limited to the illuminated display unit attachment 100 and the illuminated magnifier attachment 200 described above, and various attachments can be attached as shown in fig. 1.

For example, as shown in fig. 13, an air fan attachment 300 may be attached to the power supply rail 21, and a substantially drum-shaped blower 302 may be provided on a support base 301 provided on the module insertion portion 51 of the air fan attachment 300. In this way, the attachment has the blower 302 that blows air to the vicinity of the products S with the electric power supplied from the supply electrode portions 37P and 37M, and thereby can generate an air curtain to the products S such as fresh goods placed on the shelf 6 to suppress the deterioration of the products S, or can transmit the taste of the products S to the user M to exhibit the effect of using air such as presentation by smell.

Further, for example, as shown in fig. 14, a lower illumination attachment 400 provided with a lighting fixture (lower illuminating portion) 401 such as a fluorescent tube on the module insertion portion 51 on the premise of being inserted into the lower installation groove 35 may be attached to the lower installation groove 35 of the power supply rail 21. In this way, the attachment includes the lighting fixture 401 for irradiating the space below the shelf plate 6 with illumination light by the power supplied from the power supply electrode portions 37P and 37M, and thereby can clearly and conspicuously display the commodity S placed below the shelf plate 6 to the user M or can function as underfoot lighting for irradiating the underfoot of the user M.

For example, as shown in fig. 15, a motion picture display attachment 500 may be attached, which electrically connects a motion picture display portion 501 (a member having a storage device such as a hard disk or a memory and displaying motion picture data stored in the storage device) that can be provided on the front side of power supply rail main body 31 in place of decorative plate 33 to module insertion portion 51 on the premise of being inserted into lower installation groove 35. In this way, the accessory device includes the animation display unit 501, and thus, a large amount of information relating to the product S can be visually displayed to the user M.

As in the above-described animation display unit 501, a front display unit 600 having a card holder may be provided on the front side of the power supply rail main body 31 instead of the decorative plate 33. As shown in fig. 16, the front display unit 600 has a card holder 602 integrally formed on a mounting plate 601 having 2 fitting grooves 38 formed therein. Further, by fitting the fitting projection 39 on the front side of the power supply rail main body 31 into the 2 fitting grooves 38 of the installation plate 601, the front display unit 600 can be attached to the power supply rail 21 as shown in fig. 17.

By using such a front display unit 600, the card holder 602 and the chassis 6 can be arranged at positions overlapping in the vertical direction, and space saving can be achieved. In the example shown in fig. 17, the following are configured: an L-shaped angle member 81 is fixed to the front side end of the chassis 6, and a 2 nd installation rail 82 provided on the rear side of the power supply rail body 31 is installed by a 2 nd locking claw 82a formed at the upper end thereof being locked in a gap between the front side end of the chassis 6 and the L-shaped angle member 82. In addition, although the power supply rail 21 is provided separately from the shelf plate 6 in the above description, the present invention is not limited to this, and the power supply rail main body 31 may be formed integrally with the shelf plate 6 (or assembled from the beginning), that is, the power supply rail 21 may be provided integrally with the display shelf 1.

As shown in fig. 18 and 19, for example, RFID communication device attachments 700A and 700B each having an RFID transceiver 701 and RFID antennas 702A and 702B in the unit insertion portion 51 may be attached to the power supply rail 21. Fig. 18 is an enlarged view showing a side surface of the chassis 6 on which the RFID communication device attachments 700A and 700B are mounted on the power supply rail 21, and fig. 19 is a plan view of the chassis 6 and the RFID communication device attachments 700A and 700B as viewed from the direction of arrow B in fig. 18.

In these fig. 18, 19, the RFID communication device attachment 700A, 700B includes the component insertion portion 41, the RFID transceiver 701, and the RFID antennas 702A, 702B, wherein there are 2 of the space type RFID antenna 702A and the sheet type RFID antenna 702B as the RFID antennas. An RFID tag T is attached (adhered or bound) to each article S placed on the shelf 6, and tag ID information for identifying the individual article S and information related to the article S to be attached are stored in the RFID tag T.

The RFID transmitter/receiver 701 is connected to a management device, not shown in the drawings, including a personal computer and a server, so as to be capable of transmitting and receiving information and commands via a network such as a LAN, and transmits and receives information to and from the RFID tags T attached (attached or bound) to the respective products S by wireless communication via the RFID antennas 702A and 702B in accordance with commands received from the management device.

The space-type RFID antenna 702A is a flat plate-shaped antenna that is provided upright on the shelf 6 so as to space between the products S in the arrangement of the plurality of products S, and in the illustrated example, 2 planar antenna elements 704 (each formed of a so-called patch antenna) are provided in parallel on both front and back surfaces of the main body substrate 703 in the front-back direction, and the 4 planar antenna elements 704 are connected to the RFID transmitter/receiver 701. The sheet-type RFID antenna 702B is a flat-plate-shaped antenna laid on the surface of the shelf 6 on which the product S is placed, and in the illustrated example, 6 planar antenna elements 704 are juxtaposed inside the main body sheet 705, and the 6 planar antenna elements 704 are connected to the RFID transmitter/receiver 701. These 2 types of RFID antennas 702A and 702B are provided so that the space for placing the commodity S on each shelf 6 becomes a wireless communication area.

In this way, since the attachment includes the RFID communication device that transmits and receives information via wireless communication between the power supplied from the supply electrode portions 37P and 37M and the RFID tag T attached to the commodity S, it is possible to manage the type and the number of commodities S placed on each shelf 6, the number of times the user M takes out the commodity S, and the like.

By performing such commodity management using RFID, it is possible to perform various commodity management, for example, position management for grasping where commodities and the like arranged in which area are sold in the case where the same type of commodities are arranged in a plurality of areas in a shop (for example, there are cases where beer is set in a dedicated beer rack and beer is arranged in a seasonal food), and grasping the number of times of taking out commodities S placed on the display rack 1 (counting of the number of times of taking out and returning from the rack plate 6 is also possible).

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit and scope of the invention. Next, such a modification will be described.

(1) Adapted to the case of hook-and-loop type display stands

In the above embodiment, the case of applying the power supply rail and the power supply system of the present invention to a shelf-type display rack having a plurality of shelves on which display commodities are placed has been described, but the present invention is not limited to this, and the power supply rail and the power supply system of the present invention may be applied to other hook-type display racks having a plurality of hooks for hanging display commodities, for example.

Fig. 20 and 21 are external views of the whole of the hanger type display rack according to the modification, fig. 20 is a side view of the rack corresponding to fig. 1, and fig. 21 is a front view of the rack corresponding to fig. 2. Fig. 22 is a plan view as seen from the direction of arrow C in fig. 21, and corresponds to fig. 4. In the drawings, the same reference numerals are given to the same parts as those in fig. 1, 2, and 4, and the description thereof will be omitted as appropriate.

In fig. 20, 21, and 22, the 1 st brackets 802 are fixed to the front side surfaces of the respective legs 3 and 4 in the fixing holes 11 positioned at the same height (firmly fixed by engagement of the fixing claws 12 (not shown in fig. 20; see fig. 3)), and the hooking guide 803 is provided along the left-right direction so as to straddle between the 21 st brackets 802 fixed at the same height. The power supply rail 21 is provided via 2 nd brackets 804 (not shown in fig. 21 and 22) fixed to the vicinities of both end portions of the hanger rail 803. The hanger rail 803 and the power supply rail 21 are formed in substantially the same rectangular parallelepiped shape, and are fixed in a parallel arrangement relationship in which the hanger rail 803 is located on the front side and the power supply rail 21 is located on the rear side (in addition, the left-right direction, that is, the longitudinal direction of the hanger rail 803 corresponds to a predetermined display direction as in the above-described embodiment, and the power supply rail 21 and the 2 installation grooves 34 and 35 and the power supply electrode portions 37P and 37M formed thereon in this modification are also arranged along the predetermined display direction).

A rear end portion of a bar-shaped hook bar (hook) 805 extending forward of the hook type display rack 801 is fixed to an upper surface of the hook rail 803, and an extension type illuminated display attachment 900 is attached to a groove 34 provided above the power supply rail 21 in the vicinity of the fixed side of the hook bar 805. The hook bar 805 and the elongated illuminated display attachment 900 are arranged in a manner so as to be aligned with (or to be aligned with) the longitudinal direction (the left-right direction; the predetermined display direction) of the hook rail 803 (or the power supply rail 21). In this way, the hook bar 805 and the elongated illuminated display attachment 900 form a pair, and a plurality of pairs (3 pairs in the illustrated example) are provided in the longitudinal direction of the hook rail 803 and the power supply rail 21. The commodity S is hung on each hanger rail 803 and displayed in a state of being overlapped in the front-rear direction.

The elongated display attachment 900 with illumination includes: the module insertion portion 51, a support base 901 provided to the module insertion portion 51, a support rod 902 provided in a configuration extending forward from the support base 901, and an illuminated display portion 903 provided at a front end portion of the support rod 902. As described above, since the corresponding hook bar 805 and the extended illuminated display attachment 900 are in the same positional relationship in the left-right direction, the illuminated display 903 of the extended illuminated display attachment 900 is disposed close to the upper side of the front end portion of the hook bar 805, and the corresponding relationship therebetween becomes clear.

Fig. 23(a) is a side view of the display portion 903 with illumination, and fig. 23(b) is a front view of the display portion 903 with illumination. The illuminated display portion 903 includes: a holder portion (display portion) 911 formed in a substantially flat plate shape as a whole, a support portion 912 having a semi-cylindrical shape fixed to a back surface (rear side surface) of the holder portion 911, a connection portion 913 formed integrally with the back surface of the support portion 912, and an LED (display irradiation portion) 914 provided on an upper surface of the support portion 912.

The holder portion 911 has the same structure as the holder portion 104 of the card holder 101 in the above embodiment, and is entirely made of a translucent resin material and has a double-plate structure with an open upper end. A card (not shown) in which prices, information, and the like are described is sandwiched in the holder portion 911, and displayed to the user M. The connecting portion 913 is formed in a hollow cylindrical shape, and the illuminated display portion 903 is provided by fitting the front end portion of the support rod 902 into the connecting portion 913. The LEDs 914 are electrically connected to the terminal portions 47 and 48 of the module insertion portion 51 via distribution wires (see the dashed line portion in fig. 20) routed through the support portion 912, the connection portion 913, the support rod 902, and the inside of the support base 901.

When the extended illuminated display attachment 900 including the illuminated display 903 is attached to the power supply rail 21, the LED914 is energized and lighted from the power supply electrode portions 37P and 37M of the power supply rail 21 via the terminal portions 47 and 48 of the module insertion portion 51 and the power distribution wire. The illumination light emitted from the LED914 irradiates the holder portion 911 from the back surface and transmits through the card inside (therefore, the card is preferably thin paper or a light-transmitting film that is easily transmitted), and the display on the holder portion 911 can be clearly and visibly displayed to the user M.

As described above, according to the present modification, the power supply system including the power supply rail 21 can be applied to the hanger type display rack 801, and the same effects as those of the above embodiment can be obtained. That is, although not particularly shown in the drawings, since the attachment can be mounted and used also in the lower installation groove 35 and the supply electrode portions 37P and 37M provided in the lower portion of the power supply rail 21, power can be supplied to both the upper side and the lower side (two directions orthogonal to the predetermined display direction) of the hook rail 803 (hook row) provided corresponding to the power supply rail 21 with a high degree of freedom of arrangement.

In the above-described modification, the arrangement direction (predetermined display direction) of the hook rail 803 and the power supply rail 21 is set to the left-right direction (horizontal direction), but the present invention is not limited to this, and for example (not particularly shown), the hook rail 803 and the power supply rail 21 may be arranged along the up-down direction. At this time, the direction (predetermined display direction) of the array (hook row) of the plurality of hook bars 805 provided correspondingly becomes the vertical direction, and the power supply rail 21 includes 2 installation grooves 34, 35 on both sides in the right-left direction orthogonal thereto, and can supply power with a high degree of freedom of arrangement.

That is, in the hook type display rack 801 according to the present modification, the hook rail 803 and the power supply rail 21 can be provided along an arbitrary direction (predetermined display direction) within a fixed-side (rear-side) vertical plane (including the vertical direction, the horizontal direction, and the oblique direction therebetween) of the hook bar 805, and the power supply rail 21 includes 2 installation grooves 34, 35 on both sides of a direction orthogonal to the arbitrary installation direction (predetermined display direction) and parallel to the same vertical plane, and can supply power with a high degree of freedom of arrangement.

The specific configuration of the above-described embodiment is not strictly limited to the contents of the present invention, and it goes without saying that the configuration can be variously modified in part along the gist of the present invention.
