Description

  The present invention relates to an attachment device for attaching a panel-like structure to a wall surface or a column. Examples of the panel-like structure include sign panels such as lighting signs and display boards, solar panels, and thin televisions.

  This type of attachment device is disclosed in Patent Document 1, for example. There, a pair of upper and lower signboard mounting rails fixed in a horizontal position on the wall surface, an illumination light source (fluorescent lamp) disposed at an intermediate position between the upper and lower rails, and the previous signboard mounting rail are engaged and mounted. Lighting signage is composed of signboard units. The signboard unit is configured as a hollow panel having an oval cross section by sticking the front body and the rear face body, and a coupling member that engages with the signboard mounting rail is provided above and below the rear face body. A recessed portion for accommodating the light source for illumination is formed in the center of the upper and lower sides of the rear body. The coupling member and the signboard mounting rail are each formed of an aluminum strip. In this way, a signboard mounting structure in which a signboard unit is mounted on a pair of upper and lower signboard mounting rails is widely used as a facade sign mounting apparatus such as a convenience store.

  When the signboard unit is attached, the signboard unit is tilted backward and the upper coupling member is suspended from the upper signboard mounting rail. Next, the posture of the signboard unit is returned to the vertical posture, and the locking claws provided on the lower coupling member are engaged with the locking shoulders of the lower signboard mounting rail. Fix and support the sign unit. When removing the signboard unit, push up the disengagement button provided on the lower coupling member against the pushing force of the spring to release the engagement between the coupling member and the lower signboard mounting rail. In the state where the signboard unit is tilted backward, the upper coupling member is removed from the upper signboard mounting rail.

  In the mounting device according to the present invention, a pair of left and right vertical mounting frames are fixed to the wall surface, and a mounting object such as a sign panel is mounted and fixed to these mounting frames. Thus, a signboard is mounted on the vertical mounting frame. A mounting device to do can be found in US Pat. There, a signboard mounting bracket is constituted by a vertically long metal fitting body fixed to the left and right of the wall surface and a movable member provided on the upper portion of the metal fitting body. An L-shaped support portion that supports the lower edge of the signboard is formed at the lower end of the metal fitting body, and a compression spring that pushes up and urges the signboard is disposed therein. The movable member is assembled so as to be vertically slidable with respect to the metal fitting body, and an inverted L-shaped support portion for supporting the upper edge of the signboard is formed at the upper end thereof.

  When a signboard is mounted on the signboard mounting bracket of Patent Document 2, the upper edge of the signboard is inserted into the support portion of the movable member and pushed up, and the entire movable member is tilted backward in a direction away from the bracket body. In this state, the lower edge of the signboard is fitted into the support portion of the metal fitting body, and the signboard is supported by a pair of left and right compression springs. The upper and lower ends of the signboard mounted on the signboard mounting bracket are supported by the support portion of the bracket body and the support portion of the movable member, and are pushed up and biased by a compression spring. When removing the signboard, the above installation procedure is reversed.

Japanese Patent No. 4217319 (paragraph numbers 0011 to 0018, FIGS. 4 and 5) Japanese Unexamined Patent Publication No. 07-181895 (paragraph numbers 0030 to 0070, FIG. 1)

  According to the illumination signboard of patent document 1, the signboard length in the left-right direction can be arbitrarily set, and the installation cost can be reduced. However, when the signboard unit is mounted on the signboard mounting rail, the signboard unit is placed on the upper signboard mounting rail while matching the height position of the upper coupling member of the signboard unit with the height position of the upper signboard mounting rail. It is necessary to hang on. In other words, it is necessary to match the height position of the connecting member and the signboard mounting rail while the connecting member on the signboard unit side is not visible, so the work of hanging the signboard unit on the upper signboard mounting rail fails. In many cases, there is a problem in ensuring the safety of work. If multiple workers perform the mounting work while supporting the left and right sides of the signboard unit, the positional relationship between the coupling member and the signboard mounting rail can be seen from the side, so that the signboard unit can be securely attached to the signboard mounting rail. It can be safely hung. However, it is inevitable that labor costs will increase during construction.

  Further, when removing the signboard unit of Patent Document 1, the disengagement button is pushed up, and further, the lower edge of the signboard unit is moved away from the wall surface to be tilted backward, and the signboard unit is supported in the state of supporting the signboard unit. It is necessary to remove the coupling member from the upper signboard mounting rail. However, since this type of signboard unit has a weight of 10 to 20 kg, when the upper coupling member is removed from the signboard mounting rail, the signboard unit may be dropped if the signboard unit grip position is not well balanced. Therefore, great care must be taken to perform the work safely.

  According to the signboard mounting bracket of Patent Document 2, the signboard can be easily mounted on the signboard mounting bracket by simply mounting the upper and lower edges of the signboard on the support portion of the movable member and the support portion of the bracket body. However, the signboard mounted on the signboard mounting bracket is merely held in the vertical direction by the urging force of the compression spring. For this reason, there is a risk of receiving an external force and rattling in the thickness direction or moving in the left-right direction. For this reason, signboards are limited to ceilings in the store where the wind and rain are blocked, the eaves of the store, etc., and are not suitable for use as facade signs exposed to wind and rain.

The object of the present invention is to hold the panel-like structure in the middle of attachment / detachment at the temporary assembly position by the base frame, and therefore even a single operator always changes the gripping position of the panel-like structure to the optimum position. Thus, an object of the present invention is to provide a panel-like structure mounting apparatus that can safely and easily attach and detach the panel-like structure.
The object of the present invention is to allow the mounting device itself to absorb lateral displacement during construction of panel-like structures arranged adjacent to each other, as well as changes in dimensions accompanying thermal expansion and contraction. An object of the present invention is to provide a panel-like structure attachment device capable of simplifying the structure of the structure attachment device and reducing the overall cost.
An object of the present invention is to provide a panel-like structure mounting apparatus suitable for supporting an illumination signboard represented by a facade sign.

As shown in FIG. 3, the base frame 2 is composed of a strip provided with a connecting wall 7 that guides and supports the panel frame 3 so as to be slidable up and down, and a front opening 8. A panel support 10 for supporting the structure 1 is disposed. The panel frame 3 is composed of a strip material having a slide wall 19 that is slidably engaged and guided by the connecting wall 7, and a plurality of latching portions 22 that are engaged and supported by the panel support 10 above and below the panel frame 3.・ 23 is provided. By inserting the panel frame 3 upward with respect to the base frame 2 from the lower surface side, as shown in FIG. 1 can be held at the temporary assembly position. By further moving the panel frame 3 upward from the temporary assembly position, as shown in FIG. 11 (b), the other retaining portion 23 is engaged with the panel support 10, and the panel-like structure 1 is moved to the main assembly position. It is characterized in that the position can be maintained.

  An engagement releasing structure for releasing the engagement between the latching portions 22 and 23 and the panel support 10 by disengaging the panel support 10 is provided inside the panel frame 3. The panel support 10 is made of a spring material, and integrally includes a passive wall 12 that can be elastically deformed in the front-rear direction and a receiving claw 14 that is provided on the upper portion of the passive wall 12 and engages and disengages with the latching portions 22 and 23. ing. The disengagement structure includes a release rod 28 that is supported by the panel frame 3 so as to be freely slidable up and down, and a plurality of operation cams 29 and 30 that are fixed to the release rod 28 corresponding to the latching portions 22 and 23. As shown in FIG. 10, the release rod 28 is pushed upward to bring the operation cams 29 and 30 into contact with the passive wall 12, thereby elastically deforming the passive wall 12 and receiving the latching portions 22 and 23. The engagement with the claw 14 can be released, and the panel support 10 can be switched to the disengagement posture.

  The base frame 2 is formed of a strip material having a C-shaped cross section, and a pair of connecting walls 7 and a fixed side wall 6 continuous to the connecting walls 7 are formed on the left and right of the front opening 8. The panel frame 3 is formed of a cross-section hat-shaped strip that opens toward the base frame 2, and slide walls 19 that are engaged and guided by the connecting wall 7 are formed on the left and right sides of the rear surface. As shown in FIG. 7, the left-right distance L 1 of the fixed side wall 6 of the base frame 2 is set to be larger than the left-right width L 2 of the slide wall 19 of the panel frame 3, and between the slide wall 19 and the fixed side wall 6 An expansion absorption gap 20 that absorbs thermal expansion in the left-right direction of the structure 1 is secured.

  A relief recess 13 that avoids contact interference with the release rod 28 is formed at the center of the left and right of the passive wall 12 of the panel support 10 to form the passive wall 12 in a bifurcated shape. A receiving claw 14 is bent at each of the upper ends of the bifurcated passive wall 12.

  The latching portions 22 and 23 provided on the panel frame 3 are constituted by a slide wall 19 of the panel frame 3 and a notch formed on the movable side wall 18 continuous to the slide wall 19. Hanging portions 24 and 25 that are engaged and supported by the receiving claws 14 of the panel support 10 are provided at the upper cutout ends of the respective latching portions 22 and 23.

  An operation unit 32 that pushes up the release rod 28 is provided at the lower end of the release rod 28. As shown in FIG. 6, the operation portion 32 is provided so as to protrude downward from the lower end of the panel frame 3 and face the lower edge of the panel-like structure 1.

  In the state where the panel-like structure 1 is held at the main assembly position, the base frame 2 is provided with a braking body 36 (see FIG. 6) that restricts the upper part of the panel frame 3 from moving back and forth.

  In the present invention, the vertically long panel frame 3 fixed to the panel-like structure 1 is inserted into the base frame 2 fixed to the attachment base W from below so that the panel-like structure 1 is attached to the attachment base W. did. Further, the panel support 10 is provided inside the base frame 2, and a plurality of latching portions 22, 23 are provided above and below the panel frame 3, and the latching portions 22, 23 are engaged and supported by the panel support 10. By doing so, the panel-like structure 1 can be held at the temporary assembly position, or can be held at the main assembly position above the temporary assembly position.

  According to the mounting device having the vertically long base frame 2 and the panel frame 3 as the connecting elements as described above, when the panel-like structure 1 is mounted on the mounting base W, the left and right positions of the base frame 2 and the panel frame 3 are set to the panel. Since it can be easily confirmed by visual observation from the upper side of the structure 1, even the single operator can surely and easily perform the initial connection between the base frame 2 and the panel frame 3. Further, the panel support 10 is automatically engaged with each of the latching portions 22 and 23 simply by moving the panel-like structure 1 after the initial connection upward, so that the panel-like structure 1 is moved to the temporary assembly position. Therefore, the panel-like structure 1 can be easily attached. Furthermore, since the panel-like structure 1 can be temporarily held at the temporary assembly position in the process of moving upward to the main assembly position, the gripping position and posture of the hand that supports the panel-like structure 1 at the temporary assembly position can be changed. By changing to an optimal position, the panel-like structure 1 can be supported in a stable state at all times. Therefore, a series of attaching / detaching operations of the panel-like structure 1 with respect to the mounting base W can be performed safely and easily. Also, when removing the panel-like structure 1 from the base frame 2, the panel-like structure 1 is temporarily held at the temporary assembly position, so that the panel-like structure 1 may be accidentally removed during removal. Even so, the panel-like structure 1 can be prevented from suddenly falling off the base frame 2 and the safety of the work can be improved.

  When an engagement release structure for releasing the engagement between the latching portions 22 and 23 and the panel support 10 is provided inside the panel frame 3, each latching can be performed only by pushing the release rod 28 upward. The panel-like structure 1 can be moved downward by releasing the engagement between the portions 22 and 23 and the receiving claws 14. Therefore, the operation of lowering the panel-like structure 1 from the main assembly position to the temporary assembly position, or further lowering the panel-like structure 1 from the temporary assembly position and removing it from the base frame 2 can be performed easily. Moreover, since the panel support body 10 is comprised by the spring material which integrally provided the passive wall 12 which can be elastically deformed back and forth, and the receiving nail | claw 14 of the upper part of the passive wall 12, the panel support body 10 is comprised by several components. Compared to the case, the structure of the panel support 10 can be simplified and the cost of the mounting device can be reduced. Further, since the passive wall 12 is elastically deformed by the operation cams 29 and 30 fixed above and below the release rod 28 to switch the panel support 10 to the disengagement posture, the shape, size, or fixing of the panel support 10 is fixed. Even if there is some variation in position or the like, the panel support 10 can be switched to the disengagement posture without any problem.

  When a pair of connecting walls 7 is provided on the left and right of the front opening 8 of the base frame 2 and a slide wall 19 is provided on the left and right of the rear surface of the panel frame 3, the pair of connecting walls 7 receive the pair of slide walls 19 and Since the connection state of the frame 3 and the base frame 2 can be maintained, the connection strength between the frames 2 and 3 can be improved. Further, since the pair of slide walls 19 can be engaged and guided by the pair of connecting walls 7, the sliding operation when the panel-like structure 1 is moved up and down with respect to the base frame 2 is stabilized, and the panel-like structure 1. It can be attached and detached smoothly. If the expansion absorption gap 20 is secured between the fixed side wall 6 of the base frame 2 and the slide wall 19 of the panel frame 3, the lateral displacement and the misalignment during construction of the adjacent panel-like structure 1 are The dimensional change accompanying thermal expansion and thermal contraction can be absorbed by the expansion absorption gap 20. For example, even when the panel-like structure 1 is expanded and deformed by receiving heat, the influence of the expansion and deformation is eliminated on the adjacent panel-like structure 1, and Damage can be eliminated.

  When the relief recess 13 is formed in the passive wall 12 of the panel support 10 and the passive wall 12 is formed in a bifurcated shape, the base frame 2 and the panel frame 3 with the panel support 10 and the disengagement structure intersecting each other. Since the base frame 2 and the panel frame 3 can be prevented from becoming unnecessarily large, the cost of the mounting device can be reduced. Further, if the catching claws 14 are bent at the upper ends of the bifurcated passive walls 12, the frictional resistance when the operation cams 29 and 30 get over the catching claws 14 is reduced, and the panel-like structure. 1 can be smoothly moved downward.

  When the latching portions 22 and 23 are formed by notches formed over the slide wall 19 and the movable side wall 18, the entire panel frame 3 is compared with the case where the latching portion is configured by fixing another part to the panel frame 3. The structure can be simplified and the weight can be reduced by the notch. Moreover, since the upper notch end of each latching part 22 * 23 is utilized as the hanging part 24 * 25, there is no waste, and the whole structure of the panel frame 3 can be further simplified and cost-reduced.

  When the operating portion 32 provided at the lower end of the release rod 28 is projected downward from the lower end of the panel frame 3 and further faces the lower edge of the panel-like structure 1, when the panel-like structure 1 is attached or detached, Even when the lower edge is supported, the operation unit 32 can be pushed up with a fingertip to disengage the panel support 10. Therefore, a series of operations when the panel-like structure 1 is attached to and detached from the base frame 2 can be quickly performed. In addition, since the operation unit 32 facing the lower edge of the panel-like structure 1 is always concealed by the panel-like structure 1, the appearance of the panel-like structure 1 may be damaged by the operation unit 32. Absent.

  When the braking body 36 is provided on the base frame 2, the braking body 36 can restrict the upper part of the panel frame 3 from moving back and forth in a state where the panel structure 1 is held at the main assembly position. Therefore, when wind pressure acts on the panel-like structure 1, it is possible to prevent the upper portion of the panel frame 3 from rattling and firmly fix and hold the panel-like structure 1.

The fixed side wall 6 and the connecting wall 7 are continuous in an L shape in a state of being orthogonal to each other, and a front opening 8 is provided between the opposing ends of the pair of left and right connecting walls 7.

  A panel support 10 that supports the facade sign 1 is fixed to the lower part of the inner surface of the base frame 2 via the panel frame 3. The panel support 10 is formed by using a stainless steel plate (spring material) having spring properties as a forming material, and a seat portion 11 that is caulked and fixed near the lower end of the mounting wall 5 of the base frame 2 and the seat portion 11. A passive wall 12 that is elastically deformable before and after being continuously inclined upward and upward is formed by bending it into a square shape. In the center of the left and right sides of the passive wall 12, an escape recess 13 is formed to avoid a contact buffer with a release rod 28, which will be described later, whereby the entire passive wall 12 is formed in a bifurcated shape. On each of the upper ends of the left and right passive walls 12, receiving claws 14 that support the facade sign 1 via the panel frame 3 are bent backward. As described above, the panel support 10 fixed in a cantilever shape with respect to the base frame 2 has the passive wall 12 when the upper and lower operation cams 29 and 30 described later pass through the front side of the panel support 10. It can be elastically deformed to exert a positive elastic force. In the free state, the panel support 10 is exposed to the outside of the frame from the front opening 8 of the base frame 2 at the receiving claw 14 and the tip of the passive wall 12.

The panel frame 3 has its mounting wall 17 bonded to the back surface of the facade sign 1 with double-sided tape, and the mounting wall 17 and the rear panel body 1B are fastened with rivets to be integrated. Further, as shown in FIG. 6, the bracket 43 fixed to the upper end of the panel frame 3 and the mounting frame 44 fixed to the upper edge of the facade sign 1 are fastened with bolts 45 so that the facade sign 1 is attached to the bracket 43. The frame 44 is suspended and fixed. A left and right horizontally long retaining piece is fixed to the upper edge of the facade sign 1, and the sign upper edge portion is pulled downward from the mounting frame 44 by suspending the retaining piece by the mounting frame 44. Is regulated. The bracket 43 is fastened and fixed to the panel frame 3 with rivets.

  As shown in FIG. 3, in order to support the facade sign 1 through the panel frame 3 by the panel support 10 described above, an upper hooking portion (hanging portion) 22 and a lower hook are formed on the upper and lower sides of the panel frame 3. A stop part (hanging part) 23 is provided. The upper latching portion 22 and the lower latching portion 23 are each constituted by a notch portion formed over the slide wall 19 and the movable side wall 18 of the panel frame 3, and the upper latching portion 22 or the upper latching portion 23 on the upper side of the lower latching portion 23. Hanging portions 24 and 25 that are received and supported by the receiving claws 14 of the panel support 10 are provided at the cutout ends. In a state where the hanging portion 24 of the upper hanging portion 22 is supported by the panel support 10, the facade sign 1 is held at the temporary assembly position shown in FIG. 11A, and the hanging portion 25 of the lower hanging portion 23 is held. Is supported by the panel support 10, the facade sign 1 is held at the main assembly position shown in FIG. As described above, the panel support structure includes the panel support 10 incorporated in the base frame 2, and the upper and lower latch portions 22 and 23 provided above and below the panel frame 3.

  In the temporary assembly position and the main assembly position, in order to release the engagement between the upper latching portion 22 or the lower latching portion 23 and the panel support 10 and to enable the facade sign 1 to move downward, the panel frame 3 A disengagement structure is provided inside. Furthermore, release pieces 37 for forcibly switching the panel support 10 to the disengagement posture are provided on the left and right slide walls 19 below the upper latch 22 (see FIG. 3). On the lower part of the release piece 37, a climbing guide surface 38 that makes the climbing of the panel support 10 with respect to the receiving pawl 14 smooth is formed obliquely. The release piece 37 can be formed integrally with the wall 19 by pressing the slide wall 19, or can be formed of a press-molded product separate from the panel frame 3.

  3 and 4, the engagement release structure is fixed to the release rod 28 with spring pins corresponding to the release rods 28 arranged along the longitudinal direction of the panel frame 3 and the upper and lower latch portions 22, 23. An upper operation cam (operation cam) 29 and a lower operation cam (operation cam) 30 are configured. The release rod 28 is supported by a bracket 31 provided above and below the inner surface of the panel frame 3 so as to be freely slidable up and down, and an operation portion 32 for pushing up the release rod 28 is provided at the lower end thereof. The operation unit 32 is operated to move upward, and the upper operation cam 29 or the lower operation cam 30 is brought into contact with the passive wall 12 of the panel support 10, thereby forcibly elastically deforming the passive wall 12 and the panel support. 10 can be switched to the disengagement posture.

  The operation cams 29 and 30 are formed of a plastic product having a rectangular parallelepiped shape with excellent lubricity, and the rear surfaces of the operation cams 29 and 30 are located behind the panel frame 3 in a state where the engagement release structure is assembled inside the panel frame 3. It protrudes from the opening (see FIG. 3). The left and right side surfaces of the operation cams 29 and 30 in this state face the movable side wall 18 with a small gap therebetween. Further, the rear surfaces of the operation cams 29 and 30 in a state where the panel frame 3 is connected to the base frame 2 protrude from the front opening 8 of the panel frame 3 into the frame. That is, the transition trajectory of the operation cams 29 and 30 in a state where the panel frame 3 is inserted into the base frame 2 and intersects with the passive wall 12 of the panel support 10. In the lower rear corners of the operation cams 29 and 30, guide surfaces 33 and 34 for facilitating getting over the receiving claws 14 when the facade sign 1 is lowered are formed obliquely. The entire weight of the disengagement structure when not in use is supported by a lower bracket 31 that receives the lower operation cam 30, and the operation portion 32 in this state protrudes downward from the lower end of the panel frame 3. 5 and FIG. 6, it faces the support portion 41 on the lower edge of the facade sign 1. Thus, since the operation part 32 is located in the back surface side of the lower edge of the facade sign 1, when attaching and detaching the facade sign 1, the operation part 32 is easily pushed with the support part 41 supported. Can be raised. Further, since the operation unit 32 is hidden by the facade sign 1, the appearance of the facade sign 1 is not impaired by the operation unit 32.

  Although the facade sign 1 is thermally expanded in response to changes in the temperature, if the connecting gap between the base frame 2 and the panel frame 3 is tight in the left-right direction, the heat expansion in the left-right direction cannot be released. It may be deformed or damaged. In order to eliminate the deformation or breakage accompanying the expansion deformation of the facade sign 1, the thermal expansion in the left-right direction of the facade sign 1 is absorbed between the slide wall 19 and the fixed side wall 6 as shown in FIG. The expansion absorption gap 20 is secured. Specifically, the left and right distance L1 of the fixed side wall 6 of the base frame 2 is set to be larger than the left and right width L2 of the slide wall 19 of the panel frame 3 to secure the above-described expansion absorption gap 20. The left-right width of the expansion absorption gap 20 in this example was 4 mm. The expansion absorption gap 20 is also useful for absorbing a lateral displacement during construction of the facade sign 1.

  Next, a procedure for attaching and detaching the facade sign 1 to the base frame 2 will be described. It is assumed that a pair of left and right base frames 2 are fixed to the wall surface W with screws in advance according to the number of facade signs 1 to be mounted. In addition, it is assumed that a pair of left and right panel frames 3 assembled with a disengagement structure is fixed to the facade sign 1 with screws in advance. When the facade sign 1 is attached to the base frame 2, the upper end of the panel frame 3 is applied to the lower end of the base frame 2 with the support portion 41 of the facade sign 1 supported by both hands, and the left and right positioning of both sides is performed. In this state, the slide wall 19 of the panel frame 3 is inserted into the inner surface of the connecting wall 7 of the base frame 2. At this time, the left and right positions of the base frame 2 and the panel frame 3 can be easily confirmed by visually observing from the upper side of the facade sign 1, so that even the single operator can perform the initial connection between the base frame 2 and the panel frame 3. It is reliable and simple.

  The receiving claws 14 of the panel support 10 in the above state protrude from the front opening 8 of the base frame 2 to the front outer surface. Therefore, when the facade sign 1 is lifted with both hands, the upper end of the panel frame 3 comes into contact with the passive wall 12 of the panel support 10 and the slide wall 19 climbs over the passive wall 12 while elastically deforming the passive wall 12. Then, the claw 14 moves upward with the claw 14 being received. Then, as shown in FIG. 9, when the facade sign 1 is lifted up to a position where the hanging portion 24 of the upper latching portion 22 gets over the receiving claw 14, the receiving claw 14 receives the elastic force of the passive wall 12 and is imagined. As shown by the line, it suddenly enters the notch and receives the hanging part 24 as shown in FIG.

  At this time, the operator does not need to be aware of how much the upper latching portion 22 is raised, and the panel support 10 is automatically locked by simply lifting the facade sign 1 from the initial connection state. To support the weight of the facade sign 1. At this time, since the passive wall 12 collides with the panel frame 3 by its own elastic force and generates a collision sound at the same time when the panel support 10 is switched to the locked posture, the operator confirms the previous collision sound. Thus, it can be known that the facade sign 1 is held at the temporary assembly position shown in FIG. 1 and FIG. 9 are diagrams showing a relational structure between the lower latching portion 23 and the panel support 10, but the lower latching portion 23 and the upper latching portion 22 have the same structure. In FIG. 1 and FIG. 9, the operation of the upper latching portion 22 and the panel support 10 has been described. Similarly, since the upper operation cam 29 and the lower operation cam 30 have the same structure, the upper operation cam 29, the lower operation cam 30, and the panel support will be referred to in the following description with reference to FIGS. Ten operations will be described.

  When the facade sign 1 supported at the temporary assembly position is further pushed up, the receiving claw 14 is again received by the slide wall 19. Then, when the facade sign 1 is continuously pushed up and the hanging portion 25 of the lower retaining portion 23 rises to a position over the receiving claw 14, as shown in FIG. 9, the receiving claw 14 is elastic on the passive wall 12. The force suddenly enters the notch and receives the hanging part 25 of the lower hanging part 23 as shown in FIG. At this time, the operator does not need to be aware of how much the lower latch 23 is raised, and the panel support 10 is automatically locked simply by lifting the facade sign 1 from the temporary assembly position. The weight of the facade sign 1 is supported by switching to the posture. At this time, since the passive wall 12 generates a collision sound at the same time when the panel support body 10 is switched to the locked posture, the operator confirms the collision sound so that the facade sign 1 is shown in FIG. It can be known that the position is held at the assembly position. In addition, the opposing space | interval of the wall surface W and the rear surface of the facade sign 1 in the state which connected the panel frame 3 to the base frame 2 is 20 mm.

  As described above, in the state where the hanging portion 25 of the lower retaining portion 23 is engaged and supported by the panel support 10 at the main assembly position, the facade sign 1 receives wind pressure, and the upper portion of the panel frame 3 is connected to the connecting wall 7. And the mounting wall 5 may move back and forth and rattle. In this way, a rubber braking body 36 is fixed to the upper inner surface of the base frame 2 in order to restrict the panel frame 3 from moving back and forth. The brake body 36 in a state where the facade sign 1 is mounted at the main assembly position is elastically deformed by the slide wall 19 and presses the upper portion of the panel frame 3 forward, thereby pressing the slide wall 19 against the connecting wall 7. It is in close contact.

  The facade sign 1 may be lowered to the temporary assembly position or removed from the base frame 2 for periodic maintenance or update of the facade sign 1 and the illumination light source 4. In that case, the lower edge of the facade sign 1 located in front of the operation portion 32 of the release rod 28 is received and held by both hands, and the left and right operation portions 32 are pushed simultaneously while the facade sign 1 is slightly pushed up. The lower operation cam 30 is brought into contact with the passive wall 12 and the panel support 10 is switched to the disengagement posture. As a result, the catching pawl 14 of the panel support 10 is detached from the lower latch 23, so that the facade sign 1 is moved downward in this state, and the catching pawl 14 is moved by the slide wall 19 as shown in FIG. Take it.

  Thereafter, the operator lifts the facade sign 1 while releasing the hand from the operation unit 32 and grasping the lower edge of the sign with both hands, so that the climbing guide surface 38 of the release piece 37 fixed to the panel frame 3 is received. The panel support 10 is forcibly switched to the disengagement posture while coming in contact with the claw 14 and getting over the receiving claw 14 and the passive wall 12. In this state, since the guide surface 33 provided at the lower corner of the upper operation cam 29 gets over the panel support 10, the upper operation cam 29 is lowered without being obstructed by the panel support 10. The passive wall 12 after the upper operation cam 29 gets over the receiving claw 14 gradually enters the upper latching portion 22 while returning and swinging forward by its own elasticity. Therefore, in a state where the facade sign 1 is lowered to the temporary assembly position, the panel support 10 is automatically switched to the disengagement posture, and the receiving claw 14 moves the hanging portion 24 of the upper retaining portion 22. Take it. Therefore, even if the facade sign 1 may be accidentally removed after the receiving pawl 14 of the panel support 10 is detached from the lower latch 23, the facade sign 1 falls off the base frame 2 and falls. It can be received at the temporary assembly position. In this state, necessary maintenance can be performed.

  When the facade sign 1 is completely removed from the base frame 2, the lower edge of the sign is supported by hand again, and the left and right operation parts 32 are simultaneously pushed up with the facade sign 1 slightly pushed up. Then, the upper operation cam 29 is brought into contact with the passive wall 12 to switch the panel support 10 to the disengagement posture. Thereafter, as described above, the panel frame 3 can be safely removed from the base frame 2 by releasing the hand from the operation unit 32 and moving the facade sign 1 downward while supporting the lower edge with both hands. it can.

  According to the above attachment device, the facade sign 1 can be temporarily held at the temporary assembly position both when the facade sign 1 is attached to the wall surface W and when the facade sign 1 is removed from the wall surface W. The attaching / detaching operation of the facade sign 1 to the wall surface W can be performed safely and reliably. In addition, in the state where the facade sign 1 is held at the temporary assembly position, the position of the hand holding the facade sign 1 can be freely changed, so that the facade sign 1 is accurately supported in an easy posture according to the posture of the worker. Therefore, a series of attaching / detaching operations can be performed safely.

  FIG. 12 shows another embodiment of the panel support structure. There, a panel support structure is configured by the locking body 50 fixed between the left and right slide walls 19 of the panel frame 3 and the panel support body 10 disposed inside the base frame 2. The locking body 50 is made of a press-molded product that is bent in an inverted L shape, and is fixed to two upper and lower portions of the panel frame 3 to constitute an upper hooking portion 22 and a lower hooking portion 23. A rod hole 51 through which the release rod 28 passes is formed in the horizontal wall of the locking body 50. In addition, an L-shaped receiving claw 14 is provided at the upper end of the panel support 10, and the receiving claw 14 receives the hanging portion 24 at the protruding end of the horizontal wall of the locking body 50. Thus, the upper and lower latching portions 22 and 23 do not necessarily have to be formed as notches, and can be configured by fixing separately formed parts to the panel frame 3. Further, the locking body 50 may be formed of a plastic molded product, a die cast molded product, or the like. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted. The same applies to the following embodiments.

  FIG. 13 shows a modification of the facade sign 1. There, the facade sign 1 is constituted only by the front panel body 1A curved in a front convex shape, and a total of four brackets 43 each having an upper and lower pair fixed to the panel frame 3, and the upper and lower edges of the facade sign 1. The facade sign 1 is integrated with the panel frame 3 by a pair of mounting frames 44 fixed to the panel frame 3. Moreover, the illumination light source 4 was arrange | positioned in the up-down center between the left-right panel frames 3, and the facade sign 1 was able to be illuminated from the rear surface side. In this case, the illumination light source 4 is preferably an LED projector in which a group of LEDs are arranged in a straight line, but may be a projector using a fluorescent lamp as a light source if necessary. Further, the illumination light source 4 may be provided at a plurality of positions above and below depending on the size of the facade sign 1. As can be understood from this embodiment, the structure of the facade sign 1 can be freely selected as required, such as a hollow structure, a dish structure with an open rear surface, or a flat panel structure, and the outer shape thereof is circular, elliptical, It can be set to an arbitrary shape as necessary, such as a square.

  FIG. 14 shows a connecting structure of the facade signs 1 adjacent to each other in the left-right direction in the facade sign 1 described in FIG. There, the left and right edges of the adjacent facade signs 1 are connected by a connecting frame 47 made of vertically long strips to prevent a gap from being formed between the adjacent facade signs 1. The connecting frame 47 is made of rubber, plastic, or aluminum and has a cross-sectional shape. A connecting groove 48 for receiving the left and right edges of the facade sign 1 is formed on the left and right sides of the connecting frame 47. As described above, in order to absorb the expansion deformation of the facade sign 1, the expansion absorption gap 20 is provided between the fixed side wall 6 of the base frame 2 and the slide wall 19 of the panel frame 3. The depth of the connecting groove 48 in the left-right direction is set to a length that can absorb expansion deformation.

  In addition to the above embodiment, the number of the base frame 2 and the panel frame 3 per unit of the facade sign 1 can be set to 3 to 4 according to the difference in the left and right dimensions of the facade sign 1, and in that case It is sufficient that a panel support structure and a disengagement structure are provided at least between the base frame 2 and the panel frame 3 arranged on both side ends. The brake body 36 does not need to be a rubber molded product, and can be constituted by a bolt. In that case, the panel frame 3 can be stretched and fixed by screwing the bolts closer to the upper end of the panel frame 3 and pressing the tip of the bolts against the base frame 2. Further, the fixing structure of the panel frame 3 to the facade sign 1 does not have to be the rivet fastening structure described in the embodiment or the fastening structure using a bracket, but a fastening structure using screws or bolts and nuts, or a blind rivet. The fastening structure used may be used.

  The panel support 10 does not need to be configured by a leaf spring. For example, an engagement arm supported by the base frame 2 so as to be able to swing back and forth, and the engagement arm swings and urges the engagement arm toward the front of the base frame 2. The panel support body 10 can be comprised with a coil spring. In that case, an inclined surface corresponding to the passive wall 12 and a structure corresponding to the receiving claw 14 may be provided on the engagement arm. The mounting device according to the present invention can be applied as a solar panel mounting base or a wall-mounting bracket of a thin television.
