Description

[Technical field]

[0001] The present disclosure relates to a hanging device for a display and a display including the same. [Background technology]

[0002] Conventionally, in stores and public facilities, displays (i.e., display devices) are installed to display various information to customers, users, etc. Displays are sometimes installed in a state of being suspended from structures such as ceilings and walls.

[0003] For example, a device for hanging a display panel from a ceiling is known that includes a power cable that transmits externally supplied power to the display panel, four hanging materials with one end fixed to the display panel and the other end connected to the ceiling, and hanging material winding machines that are provided in the middle of each hanging material and wind up at least a portion of each hanging material to change at least one of the position and posture of the display panel (see Patent Document 1).

[0004] For example, in a display device in which the display device body is suspended from the ceiling by a hanging cord, a reel is attached to a mounting part of a chassis that protrudes into an open space formed in both upper corners, and the display device body is suspended by a hanging cord wrapped around the reel (see Patent Document 2).

[0005] [Patent Document 1] JP 2020-126119 A [Patent Document 2] JP 2000-19981 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the conventional technology described in Patent Document 1, a hanging material winding machine for winding up each hanging material (i.e., hanging member) is provided at the middle part of each hanging material, making the device configuration complicated.

[0007] Furthermore, in the conventional technology described in Patent Document 1, when changing the position of the display panel (i.e., the hanging height), it becomes necessary to control the amount of each hanging material taken up by each hanging material take-up machine.

[0008] Furthermore, in the conventional technology described in Patent Document 1, a configuration may be adopted in which the display panel is suspended by a power cable instead of a hanging material, and the power cable is wound up by a cable winder. However, from the viewpoint of stable power supply to the display panel, it is not preferable to apply excessive tension to the power cable by suspending the display panel. Moreover, in the conventional technology described in Patent Document 1, no special consideration is given to suspending the display main body at a desired position by winding up both the hanging material and the power cable. The same is true for the conventional technology described in Patent Document 2.

[0009] Therefore, the main objective of the present disclosure is to provide a hanging device for a display, which can hang a display main body including a display panel at a desired position by winding up a hanging member and a power cable with a simple configuration, and a display equipped with the same. [Means for solving the problem]

[0010] The hanging device for a display disclosed herein is a hanging device for a display that holds a display main body including a display panel in a suspended state from a structure, and is configured to include one or more rope-like hanging members that connect the display main body to the structure, a power cable that connects the display main body to a power source provided on the structure, a housing attached to the display main body, a first pulley housed in the housing for winding up each of the hanging members, and a second pulley housed in the housing for winding up the power cable.

[0011] The display of the present disclosure includes the display hanging device and a display main body including a display panel. Effect of the Invention

[0012] According to the present disclosure, the display hanging device can suspend a display main body including a display panel at a desired position by winding up the hanging member and the power cable with a simple configuration. [Brief description of the drawings]

[Figure 11] FIG. 4 is an explanatory diagram showing a modified example of the mounting member shown in FIG. 3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The first invention made to solve the above problem is a hanging device for a display that holds a display body including a display panel in a suspended state from a structure, and is configured to include one or more rope-like hanging members connecting the display body to the structure, a power cable connecting the display body to a power source provided on the structure, a housing attached to the display body, a first pulley housed in the housing for winding up each of the hanging members, and a second pulley housed in the housing for winding up the power cable.

[0015] According to this, by winding up the hanging member and the power cable using a simple configuration including the first pulley and the second pulley, it is possible to hang the display main body including the display panel at a desired position.

[0016] In a second aspect of the present invention, the first pulley has an outer diameter smaller than that of the second pulley.

[0017] This makes it possible to prevent the outer diameter of the first pulley from becoming excessively large.

[0018] In a third aspect of the present invention, the second pulley has an inner diameter smaller than the inner diameter of the first pulley.

[0019] This makes it possible to ensure the required amount of power cable taken up by the second pulley without increasing the outer diameter of the second pulley.

[0020] In a fourth aspect of the present invention, the width of the groove of the second pulley is larger than the width of the groove of the first pulley.

[0021] This makes it possible to ensure the required amount of power cable taken up by the second pulley without increasing the outer diameter of the second pulley.

[0022] In a fifth aspect of the present invention, a plurality of the hanging members are provided, and the first pulley has grooves corresponding to the respective hanging members.

[0023] This allows the display body to be stably suspended at a desired position using a plurality of suspension members.

[0024] In addition, the sixth invention is configured such that each of the hanging members is connected to the corresponding groove at a different position in the circumferential direction in order to suppress the difference in the amount of each hanging member taken up by the first pulley.

[0025] This makes it easy to reduce the difference in the amount of winding of each of the hanging members by the first pulley, thereby making it possible to prevent unintended tilting of the display main body, etc.

[0026] In addition, a seventh aspect of the present invention is configured such that the device further includes a rotating shaft to which the first pulley is attached, and the second pulley is disposed coaxially with the rotating shaft.

[0027] This makes it possible to arrange the first pulley and the second pulley while preventing the housing from becoming too large.

[0028] In an eighth aspect of the present invention, the second pulley is fixed to the rotating shaft.

[0029] This makes it possible to drive the first pulley and the second pulley with a simple configuration.

[0030] In addition, the 9th invention is further provided with a mounting member that is attached by a screw into a screw hole of a predetermined standard that is pre-formed in the display main body, and the housing is configured to be attached to the display main body via the mounting member.

[0031] This allows the display hanging device to be easily attached to the display main body by utilizing screw holes of a predetermined standard that the display main body has.

[0032] In a tenth aspect of the present invention, the mounting member has an X-shape, and portions of the mounting member extending in four directions are attached to the display main body by screws.

[0033] This makes it possible to realize a mounting member for mounting the display hanging device to the display main body with a simple structure.

[0034] In addition, an eleventh aspect of the present invention is configured to further include guide tubes attached to the display main body and through which the hanging members are respectively inserted.

[0035] This allows the display body to be stably suspended by the suspension members. Also, by adjusting the position of the upper end of the guide tube (i.e., the outlet of each suspension member), unintended tilt of the display body caused by misalignment between the center of gravity of the display body and the outlet of each suspension member in the housing can be suppressed.

[0036] A twelfth aspect of the present invention is a configuration further comprising a power outlet electrically connected to the power cable.

[0037] According to this, by configuring the plug on one end of the cord for supplying power to the display to be able to be inserted into the power outlet of the display hanging device, a stable power supply for the display can be secured regardless of the position of the display body (i.e., the amount of winding of the hanging components and power cable).

[0038] In a thirteenth aspect of the present invention, the power outlet is attached to an outer wall of the housing.

[0039] This allows the plug provided at one end of the cord for supplying power to the display to be easily attached to and detached from the display suspension device.

[0040] In addition, the fourteenth invention is configured such that a rail-shaped wiring device is attached to the structure, the hanging member is connected to the structure via the wiring device, and the power cable is connected to the power source via the wiring device.

[0041] This makes it possible to connect the hanging member and the power cable to the structure with a simple configuration.

[0042] A fifteenth aspect of the present invention is a display comprising the above-mentioned display hanging device and a display main body including a display panel.

[0043] According to this, the display main body including the display panel can be suspended at a desired position by the display suspension device having a simple configuration.

[0044] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In the following description, the up-down and left-right directions of the display 1 and its components are defined according to the directions of the arrows shown in Fig. 1. Furthermore, the display panel 2 side of the display main body 3 and the opposite side are defined as the front direction and the rear direction, respectively.

[0045] Fig. 1 is an explanatory diagram showing the configuration of the front side of a display 1 equipped with a suspension device for a display 4 (see Fig. 2) according to an embodiment. Fig. 2 is an explanatory diagram showing the configuration of the rear side of the display 1 shown in Fig. 1. Fig. 3 is an exploded perspective view of the main parts of the display 1 equipped with the suspension device 4.

[0046] Display 1 is a display device for displaying various information to customers, users, etc. in stores, public facilities, etc. As shown in Figs. 1 to 3, display 1 comprises a display body 3 including a display panel 2, and a display hanging device 4 (hereinafter simply referred to as hanging device 4) attached to the rear (i.e., back) of display body 3. A known panel (for example, a liquid crystal panel or an organic EL panel) is used for display panel 2.

[0047] The hanging device 4 holds the display main body 3 in a suspended state from a structure (e.g., a ceiling or a wall) located above the height of an average person. The display main body 3 is suspended from the ceiling by two wires 6, 7 (an example of a cord-like hanging member) extending upward from the hanging device 4. In this embodiment, an example is shown in which the two wires 6, 7 are connected to the ceiling via an existing lighting rail 8. In the following, when it is necessary to distinguish between the two wires 6, 7, they will be referred to as the left wire 6 and the right wire 7, respectively.

[0048] The lighting rail 8 is a rail-shaped wiring device to which lighting fixtures such as pendant lights and spotlights are attached. Hook members 11 and 12 to which the upper ends of the wires 6 and 7 are respectively attached are attached to the rail portion of the lighting rail 8. The hook members 11 and 12 are made of an insulator and therefore have high electrical insulation properties.

[0049] Furthermore, an upper end 13A of a power cable 13 extending upward from the suspension device 4 is electrically connected to the lighting rail 8. As a result, the power cable 13 is connected to a power source (not shown) via the lighting rail 8, and power is supplied from the power source to the suspension device 4. On the lighting rail 8, the upper end 13A of the power cable 13 is located midway between the hook members 11 and 12. The power supplied to the suspension device 4 is further supplied to the display main body 3 via a power cord 14.

[0050] In this embodiment, the wires 6, 7 and the power cable 13 are connected to the ceiling and the power source provided on the ceiling via the lighting rail 8, but the lighting rail 8 may be omitted. In that case, the hook members 11, 12 may be attached directly to the ceiling. Also, the upper end 13A of the power cable 13 may be connected to a lighting outlet provided on the ceiling.

[0051] 2 and 3, the hanging device 4 is attached to the rear of the display 1 via a mounting member 15. The mounting member 15 is a flat member having a substantially rectangular shape. The hanging device 4 can be fixed to one surface of the mounting member 15 (i.e., the rear surface 15A) by screwing or adhesive.

[0052] Generally, a display body may have a plurality of screw holes provided in advance in accordance with a predetermined standard. In this embodiment, the display body 3 has four screw holes 16 in accordance with the VESA (Video Electronics Standards Association) standard, as shown in FIG. 3. The mounting member 15 is fixed by screws 17 using the screw holes 16. In this manner, the suspension device 4 can be easily attached to the display body by using the screw holes of the predetermined standard (i.e., existing screw holes) that the display body 3 has.

[0053] The mounting member 15 has tubular wire guides 18 and 19, through which the wires 6 and 7 are inserted, on the left and right sides of the upper part thereof. The wire guides 18 and 19 have the same configuration and extend substantially linearly in the vertical direction. The wire guides 18 and 19 have upper ends connected to guide tubes 21 and 22, through which the wires 6 and 7 are inserted, respectively. The guide tubes 21 and 22 have the same configuration and extend substantially linearly in the vertical direction so as to extend the wire guides 18 and 19 upward. At least a part of the circumferential surface of the guide tubes 21 and 22 may be attached to the rear part of the display main body 3 (for example, fixed by adhesive or the like). The mounting member 15 has a cable guide 23, which has a through hole through which the power cable 13 is inserted in the vertical direction, at the center of the upper part thereof.

[0054] The upper ends 21A, 22A of the guide tubes 21, 22 (i.e., the exits of the wires 6, 7 from the guide tubes 21, 22) may be located near the upper edge 3A of the display main body 3. By adjusting the positions of the upper ends 21A, 22A of the guide tubes 21, 22, it is possible to suppress unintended tilting of the display main body 3 caused by a misalignment between the center of gravity of the display main body 3 and the exits of the wires 6, 7 in the suspension device 4. Preferably, the upper ends 21A, 22A of the guide tubes 21, 22 are located on a virtual plane that passes through the center of gravity of the display main body 3 and is parallel to the surface of the display panel 2. In that case, the guide tubes 21, 22 may have a configuration in which a part of them (for example, the upper part) is curved in order to adjust the positions of the upper ends 21A, 22A.

[0055] Further, sub-wire attachment parts 26, 27 to which the upper ends of sub-wires 24, 25 (see FIG. 2) are respectively connected are provided on the left and right lower parts of the mounting member 15. The sub-wire attachment parts 26, 27 are preferably located on downward extensions of the guide tubes 21, 22, respectively. The lower ends of the sub-wires 24, 25 are respectively connected to a structure located below, such as a floor. The position of the display main body 3 (particularly the position in the front-rear and left-right directions) is stably maintained by the sub-wires 24, 25.

[0056] The sub-wires 24, 25 are installed after completing the position adjustment of the display main body 3 by winding up the wires 6, 7 described later (i.e., the final positioning of the display main body 3). The suspension device 4 includes an operation handle 32 that is detachably provided on the housing 31 (see FIG. 4 described later). As described later, a user (for example, a worker who installs the display 1) can manually wind up the wires 6, 7 by rotating the operation handle 32.

[0057] 1 and 2 show an example in which the display main body 3 is arranged so that the rectangular display panel 2 (i.e., the screen) is vertically long, but the display main body 3 may be arranged so that the display panel 2 is horizontally long. Also, the sub-wire attachment portions 26, 27 and the sub-wires 24, 25 may be omitted.

[0058] Next, the structure and operation of the suspension device 4 will be described in detail.

[0059] Fig. 4 is a perspective view showing a main part of the internal structure of the suspension device 4. Fig. 5 is an exploded perspective view of the suspension device 4 shown in Fig. 4. Fig. 6 is a perspective view showing the structure around the wire pulley 41 in the suspension device 4. Fig. 7 is a perspective view showing the structure around the power cable pulley 42 in the suspension device 4. Fig. 8 is a perspective view showing the configuration of the underside of the suspension device 4. Fig. 9 is an explanatory diagram showing the connection positions of the wires 6, 7 to the wire pulley 41 in the suspension device 4.

[0060] As shown in FIGS. 4 and 5, the suspension device 4 has a housing 31 forming an outer shell, an operating handle 32 provided detachably to the housing 31, and wires 6, 7 and a power cable 13 each extending from the housing 31.

[0061] The housing 31 is substantially box-shaped and contains a winding mechanism for winding up the wires 6, 7 and the power cable 13, and a power supply mechanism for supplying power to the display main body 3. However, the entire internal space of the housing 31 does not need to be covered with walls, and at least a part of the housing 31 may be formed by a frame.

[0062] As shown in FIG. 4, the operating handle 32 is detachably attached to the rear wall 31A of the housing 31. More specifically, a connection end 32A (see FIG. 3) of the operating handle 32 is connected to an input shaft 33 rotatably supported on the rear wall 31A of the housing 31. An input gear 35 located on the front side and a ratchet gear 36 located on the rear side are attached to the input shaft 33. As a result, the input gear 35 and the ratchet gear 36 rotate integrally with the input shaft 33. The ratchet gear 36 constitutes a ratchet mechanism together with a stopper 37 attached to the rear wall 31A of the housing 31. Although not shown, a lever is provided on the housing 31 (i.e., the rear wall 31A) for a user to operate the stopper 37. When the user operates the lever, the stopper 37 is released from the engagement with the ratchet gear 36.

[0063] The housing 31 accommodates a winding mechanism, including a wire pulley 41 (an example of a first pulley) for winding the wires 6, 7, and a power cable pulley 42 (an example of a second pulley) for winding the power cable 13.

[0064] As shown in FIG. 5, the wire pulley 41 is composed of a front pulley 45 having a groove 45A around which the left wire 6 is wound, and a rear pulley 46 having a groove 46A around which the right wire 7 is wound. In this embodiment, the grooves 45A and 46A have widths equal to the diameters of the left wire 6 and the right wire 7, respectively. That is, the left wire 6 and the right wire 7 are wound in a single row around the grooves 45A and 46A. The front pulley 45 and the rear pulley 46 are both fixed to an output shaft 49 (an example of a rotating shaft). The output shaft 49 is inserted into the shaft holes 45B and 46B of the front pulley 45 and the rear pulley 46. As a result, the front pulley 45 and the rear pulley 46 rotate integrally with the output shaft 49. That is, the wires 6, 7 are simultaneously wound around the front pulley 45 and rear pulley 46 that rotate in the winding direction, and are simultaneously unwound from the front pulley 45 and rear pulley 46 that rotate in the opposite direction to the winding direction.

[0065] The output shaft 49 extends in the front-rear direction, and its base end side is rotatably supported by the rear wall 31A of the housing 31. The tip side of the output shaft 49 is supported by a substantially U-shaped bracket 51. The bracket 51 has a through hole 51A into which the tip of the output shaft 49 is inserted. Both ends 51B of the bracket 51 are fixed by screws 54 to mounting blocks 53 provided on the rear wall 31A of the housing 31.

[0066] An output gear 57 is attached to the output shaft 49 rearward of the rear pulley 46. The output gear 57 is disposed in a state of meshing with the input gear 35. This allows the power from the input shaft 33 to be transmitted to the output shaft 49 via the input gear 35 and the output gear 57.

[0067] A power cable pulley 42 having a groove 42A around which the power cable 13 is wound is attached to the tip of the output shaft 49 extending forward from the through hole 51A of the bracket 51. In this embodiment, the groove 42A has a width equal to the diameter of the power cable 13. That is, the power cable 13 is wound in a single row around the groove 42A. The power cable pulley 42 is supported rotatably relative to the output shaft 49 without being fixed to the output shaft 49. As a result, the power cable pulley 42 is disposed coaxially with the wire pulley 41 (i.e., the front pulley 45 and the rear pulley 46). The power cable pulley 42 can rotate independently of the front pulley 45 and the rear pulley 46 (i.e., rotate relatively).

[0068] A spiral spring 61 is attached to the tip of the output shaft 49, behind the power cable pulley 42. The inner end of the spiral spring 61 is connected to the output shaft 49. Alternatively, the inner end of the spiral spring 61 may be connected to the bracket 51. Meanwhile, the outer end of the spiral spring 61 is connected to the power cable pulley 42. As a result, the power cable pulley 42 is constantly biased by the spiral spring 61 to rotate in the direction of winding up the power cable 13.

[0069] When the display main body 3 descends, the power cable 13 is unwound from the power cable pulley 42 against the biasing force of the spiral spring 61. When the display main body 3 ascends, the power cable 13 is wound up around the power cable pulley 42 by the biasing force of the spiral spring 61. This allows the length of the power cable 13 between the lighting rail 8 and the display main body 3 to be appropriately adjusted by following the winding or unwinding of the wires 6, 7.

[0070] In addition, in the suspension device 4, it is also possible to configure the power cable pulley 42 to be fixed to the output shaft 49. In that case, the power cable pulley 42 rotates integrally with the wire pulley 41. This allows the wire pulley 41 and the power cable pulley 42 to be driven by a simple configuration. In this configuration, the spiral spring may be omitted.

[0071] A slip ring 63 is provided as a power supply mechanism in front of the power cable pulley 42. A rotating portion 63A of the slip ring 63 is fixed to the front wall 42B of the power cable pulley 42 and can rotate together with the power cable pulley 42. The lower end of the power cable 13 wound around the power cable pulley 42 is electrically connected to the rotating portion 63A of the slip ring 63. On the other hand, a fixed portion 63B of the slip ring 63 is electrically connected to one end of the internal cable 65 and is held stationary regardless of the rotation of the power cable pulley 42. The other end of the internal cable 65 is electrically connected to a power outlet 66 (see FIG. 8) provided on the lower wall 31B (an example of the outer wall of the housing 31) of the housing 31. A plug 14A of the power cord 14 of the display main body 3 is connected to the power outlet 66.

[0072] 6, the left wire 6 unwound from the front pulley 45 passes through a left opening 67 for the wire provided in the upper wall 31C of the housing 31 and extends to the outside of the housing 31. As shown in FIG. 2, the left wire 6 extending from the housing 31 extends diagonally upward to the left, passes through the wire guide portion 18 and the guide tube 21, and then extends vertically to the lighting rail 8.

[0073] The right wire 7 unwound from the rear pulley 46 passes through a right opening 68 for the wire provided in the upper wall 31C of the housing 31 and extends to the outside of the housing 31. As shown in FIG. 2, the right wire 7 extending from the housing 31 extends obliquely upward to the right and passes through the wire guide portion 19 and the guide tube 22, and then extends vertically to the lighting rail 8.

[0074] 7, the power cable 13 unwound from the power cable pulley 42 passes through a central opening 69 for the power cable 13 provided in the upper wall 31C of the housing 31 and extends outside the housing 31. The power cable 13 extending from the housing 31 extends upward and passes through the cable guide portion 23, and then extends vertically to the lighting rail 8, as shown in FIG.

[0075] 9, the wires 6, 7 are preferably connected to the groove 45A of the front pulley 45 and the groove 46A of the rear pulley 46 at different positions in the circumferential direction. That is, in the circumferential direction (i.e., when viewed from the direction of the rotation shaft 70), the connection position 71 of the left wire 6 to the front pulley 45 is preferably set to a position different from the connection position 72 of the right wire 7 to the rear pulley 46. This makes it possible to easily suppress the difference in the amount of winding by the front pulley 45 and the rear pulley 46.

[0076] In the suspension device 4, a starting point 75 of the left wire 6 unwound from the front pulley 45 and a starting point 76 of the right wire 7 unwound from the rear pulley 46 are at different positions in the circumferential direction. A connection position 71 of the left wire 6 is set at a position moved a predetermined amount (smaller than the amount of the left wire 6 wound around one turn) from the starting point 75 in the winding direction of the left wire 6. Similarly, a connection position 72 of the right wire 7 is set at a position moved a predetermined amount (smaller than the amount of the right wire 7 wound around one turn) from the starting point 76 in the winding direction of the right wire 7. With this configuration, even if the front pulley 45 and the rear pulley 46 rotate in the winding direction (see the arrows in FIG. 9), the positions of the starting points 75 and 76 do not fluctuate significantly in the circumferential direction.

[0077] A user of the display 1 having the above-mentioned configuration first locks the display main body 3 to the lighting rail 8 with the wires 6 and 7 extending from the hanging device 4. The user also connects the power cable 13 extending from the hanging device 4 to the lighting rail 8. At this time, the wires 6 and 7 and the power cable 13 are in a state of being sufficiently unwound from the wire pulley 41 and the power cable pulley 42, respectively. As a result, the initial position of the display main body 3 becomes the position where the display main body 3 is lowered to the lowest.

[0078] Thereafter, the user operates the operating handle 32 to wind up the wires 6, 7 around the wire pulley 41. This causes the display main body 3 to gradually rise from the initial position. At this time, the power cable 13 is wound up by an appropriate amount around the power cable pulley 42 due to the biasing force of the spiral spring 61.

[0079] When the user raises the display body 3 to a desired height, the user's work of hanging the display body 3 (i.e., positioning the display body 3) is completed. If the user needs to lower the display body 3, the wire pulley 41 can be reversed (i.e., rotated in the payout direction of the wires 6, 7) by releasing the engagement of the stopper 37 with the ratchet gear 36. This allows the user to pay out the wires 6, 7 by the required amount and lower the display body 3 to the desired position.

[0080] FIG. 10 is an explanatory diagram showing a modified example of the wire pulley 41 and the power cable pulley 42 in the suspension device 4. As shown in FIG.

[0081] In the above-described suspension device 4 (see, for example, FIG. 4), an example has been shown in which the widths of the grooves 45A, 46A of the front pulley 45 and the rear pulley 46 are set to be relatively narrow in relation to the diameters of the wires 6, 7. Also, an example has been shown in which the width of the groove 42A of the power cable pulley 42 is set to be relatively narrow in relation to the diameter of the power cable 13. However, the present invention is not limited to these examples, and various modifications are possible to the shapes of the wire pulley 41 and the power cable pulley 42.

[0082] For example, as shown in Fig. 10, the width of the groove 45A of the front pulley 45 can be set so that multiple rows (two rows here) of wires 6 can be arranged in the width direction. The same applies to the width of the groove 46A of the rear pulley 46. However, in Fig. 10, only the innermost wires 6, 7 are shown. Also, the width of the groove 42A of the power cable pulley 42 can be set so that multiple rows (three rows here) of power cables 13 can be arranged in the width direction. However, in Fig. 10, only the innermost wires 6, 7 and the innermost power cable 13 are shown.

[0083] The outer diameter R1 of the front pulley 45 and the rear pulley 46 is preferably set to be smaller than the outer diameter R2 of the power cable pulley 42. This makes it possible to prevent the outer diameter of the wire pulley 41 from becoming excessively large.

[0084] In addition, it is preferable that the inner diameter R4 of the power cable pulley 42 (i.e., the diameter of the inner circumference of the groove 42A) is set smaller than the inner diameter R3 (i.e., the diameter of the inner circumference of the groove 45A and the groove 46A) of the front pulley 45 and the rear pulley 46. This makes it possible to ensure the necessary winding amount of the power cable 13 by the power cable pulley 42 without increasing the outer diameter of the power cable pulley 42.

[0085] In addition, since the diameter of the power cable 13 is larger than the diameters of the left wire 6 and the right wire 7, it is preferable to set the width W2 of the groove 42A of the power cable pulley 42 larger than the width W1 of the grooves 45A, 46A of the front pulley 45 and the rear pulley 46. This makes it possible to ensure the necessary winding amount of the power cable 13 by the power cable pulley 42 without increasing the outer diameter of the power cable pulley 42.

[0086] Fig. 11 is an explanatory diagram showing a modified example of the mounting member 15 shown in Fig. 3. Regarding the display 1 including the modified mounting member 115, matters that are not specifically mentioned below are the same as those in the case of the display 1 described above.

[0087] In the above-described suspension device 4 (see, for example, FIG. 2), an example has been shown in which the mounting member 15 is a substantially rectangular, flat-plate-like member. However, the present invention is not limited to this example, and the shape of the mounting member 15 can be modified in various ways.

[0088] Instead of the above-mentioned mounting member 15, for example, as shown in Fig. 11, a mounting member 115 in the form of a flat plate having a substantially X-shape can be used. The mounting member 115 has arms 115A-115D as portions extending in four directions. The mounting member 115 is fixed to the screw holes 16 of the display main body 3 by screws 17, and a spacer 117 is interposed between the mounting member 115 and the display main body 3. This ensures a predetermined gap between the mounting member 115 and the display main body 3.

[0089] The left wire 6 extending from the housing 31 extends diagonally upward to the left and passes through a left guide hole 121 provided in the left upper arm 115A of the mounting member 115, then extends vertically to reach the lighting rail 8. The right wire 7 extending from the housing 31 extends diagonally upward to the right and passes through a right guide hole 122 provided in the right upper arm 115B of the mounting member 115, then extends vertically to reach the lighting rail 8.

[0090] As described above, the embodiments have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to these, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the above embodiments to create new embodiments.

[0091] For example, although an example has been shown in which the suspension device 4 uses two wires 6 and 7, only one wire may be used. In that case, for example, a configuration in which one ends (e.g., upper ends) of the wires 6 and 7 described above are connected to each other may be adopted.

[0092] Further, although an example in which wire pulley 41 is configured from two pulleys (that is, front pulley 45 and rear pulley 46) has been shown, wire pulley 41 may be configured from one pulley having a plurality of grooves.

[0093] Further, although the suspension device 4 is driven manually (that is, by the user operating the operation handle 32) in the above example, the wire pulley 41 may be driven by an electric motor or the like. [Industrial Applicability]

[0094] The display hanging device and display equipped therewith according to the present disclosure have the advantage that the display main body including the display panel can be hung at a desired position by winding up the hanging components and power cable with a simple configuration, and are useful as a display hanging device and a display equipped therewith to be installed in stores, public facilities, etc. [Explanation of symbols]
