DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind panel for a building constituting a main part such as a fence and a balcony.

[0002]

2. Description of the Related Art Conventionally, as this type of building blind panel, there is known a panel disclosed in Japanese Utility Model Laid-Open No. 4-119572. The blindfold panel has a single rectangular panel body, and is appropriately screwed and installed between the columns to form a fence or the like. When a fence is provided over a wide area, a plurality of panel bodies are prepared, and the panel bodies are connected to each other by abutting vertical frames provided at respective side ends.

[0003]

In such a conventional building blind panel, the main part of the fence can be constituted simply by attaching a single panel body between the columns, so that the panel is easy to assemble. Since the body itself is large, its handling and transportation are extremely complicated. Therefore, for example, it is conceivable to form a panel body by mutually connecting a plurality of horizontally long panel pieces provided with a hook portion and a hook receiving portion at upper and lower side ends, respectively.

However, since the fence is usually susceptible to external force from a direction perpendicular to the surface of the panel body (expected direction) due to wind and rain or the like, for example, the shape of the hook receiving portion is formed in a cross section of "L" shape. However, if the shape of the one-side latching portion is simply shaped to hang on the latching receiving portion and these are engaged to form a panel body, an unavoidable gap generated between the latching receiving portion and the latching portion is formed. Accordingly, the connecting portion between the panel pieces is easily bent, and when the external force is large, the connecting portion may be disconnected. Further, in a fence configured by providing upper and lower frames and a pair of vertical frames around a plurality of panel bodies and abutting the vertical frames of these panel bodies with each other, an inevitable distortion in the manufacturing of the vertical frames causes the vertical frames to have a different vertical frame. There is also a problem that light leaks from the minute gap.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. Even when a plurality of panel pieces are connected to each other to form a panel body, the bending at the connection portion is reduced. In addition to reducing the number of connections, it is possible to reliably prevent the connection portion from coming off, and even when connecting the panel bodies with each other by abutting the vertical frames, light leakage from the gap between the vertical frames It is an object of the present invention to provide a blindfold panel for a building, which can surely avoid the problem.

[0006]

According to the present invention, there is provided a blindfold panel for a building, wherein the side ends of a plurality of panel pieces are connected to each other. And a hook provided on one side end of the panel piece main body, and a hook provided on the other side end of the panel piece main body for receiving and connecting with another panel piece. A hook receiving portion formed with an insertion opening that allows insertion from a prospective direction. The insertion opening is formed so as to prevent detachment of the hook portion from the hook receiving portion in the connecting posture, and The hook portion inclined from the posture is formed so as to be allowed to be inserted into the hook receiving portion, and
When the hook is loosely fitted into the hook receiving part
In both cases, the base of the latch receiving part is close to the base of the latch.
Beside, touch the tip side with the tip of the hook
And said that you are.

[0007] According to this configuration, from the connection posture when the panel pieces to be connected are connected in substantially the same plane, the hook receiving portion of one panel piece (hereinafter, referred to as a "receiving panel piece"). , The other panel piece (hereinafter, “hanging panel piece”
Is inserted through the insertion opening in a state where the hooking portion is inclined, and then the hooking panel piece is rotated so as to be in the connecting posture, so that the receiving panel piece and the hooking panel piece are interconnected. I do. In other words, the hooking portion is allowed to be inserted into the hooking receiving portion via the insertion opening only in the inclined state, and when the two panel pieces are connected to each other, the connecting direction and the direction orthogonal to the surface of the panel piece body ( It is impossible to release the hooking portion from the hooking receiving portion from any of the possible directions). For this reason, in a state where the receiving panel piece and the hanging panel piece are connected to each other, even if an external force is received from the expected direction,
The latch does not separate from the latch receiver.
In addition, since the latch receiving portion and the latch portion abut at two points,
The connecting part is subject to external force in the expected direction due to the rigidity between these two points.
You will resist. That is, the connection is made from the side
The external force acting to deflect the tie is between the above two points
Acting as a bending force on the latch and latch receiver
You. For this reason, the rigidity between the two points resists the external force.
Therefore, bending of this portion is suppressed. In addition, a hook receiving part
And the latch part are in contact with each other at the above two points,
It does not rattle under the external force as described above.

In this case, the engaging portion is formed in a substantially U-shaped cross section by a pair of flange portions and a web portion connecting them, and the engaging receiving portion is formed by a pair of flange portions and these. A receiving section main body having a substantially U-shaped cross section formed by a web portion to be connected and a receiving section main body extending from the tip of one flange portion toward the tip of the other flange portion, between the two flange portions. It is preferable that it is formed integrally with a vertical wall piece constituting an insertion opening orthogonal to the connecting direction.

According to this configuration, for example, when connecting the receiving panel piece and the hanging panel piece in the vertical direction,
First, while holding the receiving panel piece vertically and holding the retaining panel piece substantially horizontally, the front end flange portion (hereinafter, referred to as “tip flange portion”) of the retaining portion is inserted into the receiving panel piece insertion opening. And inserted into the hook receiving portion. Next, the tip flange portion is further inserted into the hook receiving portion, and the web portion of the hook portion is also inserted into the hook receiving portion while rotating the hook panel piece so as to be in the connecting posture, that is, vertical. In this case, since the web portion is inserted into the hook receiving portion while being inclined with respect to the opening surface of the insertion opening, the length of the hook portion including the web portion in the connecting direction is longer than the length of the insertion opening in that direction. Even if it is long, the latch can be completely inserted into the latch receiver through the insertion opening. As described above, when the engaging portion having the substantially U-shaped cross section is engaged with the receiving portion having the receiving portion main body having the substantially U-shaped cross section, the panel piece main body receives external force from the expected direction. , Even if a pulling force acts on the connecting part of both panel pieces up and down, the flange part on the base side of the hooking part (hereinafter referred to as “base flange part”)
) Is in contact with the other flange part (flange part where the vertical wall piece is not provided) of the opposite hanging receiving part,
The bending of the panel piece main body is suppressed against the tensile force. Further, in a state where the panel pieces are connected to each other, the length of the insertion opening in the connection direction is shorter than the length of the hook portion in that direction. The stopper does not come off the hook receiving part.

[0010]

[0011]

It is preferable that a receiving-side detent member extending toward the inside is extended from the tip of the vertical wall piece.

According to this configuration, when the two connected panel pieces receive an external force from the insertion opening side, the panel piece main bodies of the two panel pieces are respectively pulled up and down, and the base end flange portion of the latching portion is formed. Are inscribed in the other flange portion (flange portion on which the vertical wall piece is not provided) of the opposing latch receiving portion, and the front end flange portion is locked by the receiving-side flexure stopper piece. Since the locking portion is locked in the locking receiving portion at these two locations, the bending is suppressed before the connecting portion is largely bent. That is, the external force acting to deflect the connecting portion acts as a bending force for expanding the opening of the latching portion around the base flange portion inscribed in the other flange portion of the latch receiving portion. Since the rigidity of the two portions of the connecting portion opposes the force, the bending of the connecting portion is suppressed. For this reason, although the connecting portion is slightly bent before the base flange portion and the front flange portion are locked in the hook receiving portion, the bending is small. Further, since the front flange portion is hooked to the receiving-side bending stopper, even if the insertion opening is widened, the retaining portion does not come off from the retaining receiving portion.

[0014] Further, it is preferable that a hook-side flexure preventing piece extending further forward from the position of the web portion is extended from the flange portion on the base end side of the hook portion.

According to this structure, when both connected panel pieces receive an external force from the insertion opening side, the panel piece bodies of the hooking panel piece and the receiving panel piece are pulled upward and downward, respectively. The two panel pieces are about to rotate around the locking-side flexure-stopping piece of the hooking part inscribed in the other flange part of the hooking receiving part. By the action of this rotation, the tip end of the latching-side flexure stopper piece acts to lift the receiving panel piece upward, so that the tensile force acting on the panel piece body of both panel pieces is further increased. For this reason, the rigidity of the connecting part of both panel pieces resists the tensile force, and the bending of the connecting part is suppressed.

[0016] Another building blind panel according to the present invention may include a plurality of blindfold panels.
For buildings constructed by connecting the side edges of panel pieces to each other
In the blindfold panel, each panel piece is a panel piece body
And a hook provided on one side end of the panel piece main body,
The other panel provided at the other end of the panel
Receiving the hook of the flannel piece and the prospect of the hook
Latch receiver with an insertion opening that allows insertion from any direction
And a section, latching portion has a notch for guiding the insertion into the latching receptacle in the chord direction is formed in a substantially circular shape in cross section "C" shaped Rutotomoni, circumferential both At the position where the outer end has escaped,
The hook receiving portion is formed in a substantially circular shape having a reverse C-shaped cross section complementary to the outer circumferential surface of the hook portion , and the insertion opening is formed in the hook receiving portion . Of the latch in the connected position
Along with being formed to be able to prevent detachment from the hook receiving part,
Inserting the latching part inclined from the connection position into the latching receiving part
Is formed so as to allow the rotation, and one of the latching portion and the latching receiving portion is provided with a detent portion for preventing one-way rotation between the latching portion and the latching receiving portion in the connected state. It is characterized by having been done.

According to this structure, when connecting the hooking panel piece and the receiving panel piece, the hooking panel piece is first inclined with respect to the receiving panel piece, so that the string of the notch in the hooking portion is formed. The hooking portion is inserted into the hooking receiving portion by matching the direction with the direction of insertion of the receiving panel piece into the insertion opening. Next, the hanging panel piece is rotated to the connecting posture. Along with this, the latch portion rotates in the latch receiving portion formed in a complementary shape, and the portion of the latch portion facing the insertion opening,
Since the size is larger than the size of the insertion opening, even if the connecting portion bends due to an external force in the expected direction, the locking portion does not come off from the locking receiving portion. Further, since the locking portion or the locking receiving portion is provided with the rotation preventing portion, it is possible to prevent the connecting portion from rotating in one direction. For this reason, it is possible to suppress the bending of the connecting portion against an external force that attempts to rotate the connecting portion in a direction in which rotation can be prevented.

Another building blind panel according to the present invention is:
A blindfold panel for a building, comprising a panel body, an upper frame, a lower frame, and a pair of vertical frames provided on the four circumferences of the panel body, wherein the upper frame and the lower frame are framed through the pair of vertical frames. In each of the upper frame and the lower frame, each of the fore edges is slightly protruded from the outer end of each vertical frame, and each of the vertical frames is provided with a blindfold member that projects outward from the fore edge and has flexibility. It is characterized by having been done.

According to this configuration, when a plurality of building blind panels are connected to each other, for example, in the left-right direction,
When the fore edge of the upper frame and the fore edge of the lower frame are abutted respectively, and the vertical frames are abutted and connected,
The blind members provided on each vertical frame are in close contact with each other, and the gap between the vertical frames can be completely closed. For this reason, light leakage from the gap between the vertical frames can be reliably avoided. Also,
Since the fore edge of the upper frame and the lower frame protrude from the outer edge of the vertical frame, the fore edge of the upper frame and the fore edge of the lower frame can be directly abutted with each other. It is possible to accurately determine the size of the connected blindfold panel in the finding direction without being affected by the above.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a case where a building blind panel of the present invention is applied to a fence will be described with reference to the accompanying drawings. FIG. 1 is an external front view showing a fence for two spans formed by connecting the building blind panels according to the first embodiment in the left-right direction. FIG. 2 is a sectional view of FIG.
It is an A line expanded sectional view. As shown in these figures, the fence 1 is configured by a pair of building blind panels 2 and 2 facing each other in a left-right direction between a pair of right and left columns 3 and 3. The building blind panel 2 includes a frame body 9 and a panel body 5 incorporated inside the frame body 9. The frame 9 includes an upper body edge (supporting material) 6 and a lower body edge (supporting material) 7, and vertical frames 8, 8 provided laterally at both left and right ends thereof. On the other hand, the panel body 5
A plurality of horizontally long panel pieces 4 are connected to each other in the vertical direction. The upper body edge 6, the lower body edge 7, the vertical frames 8, 8 and the panel pieces 4 are all made of extruded aluminum or the like.

The upper body edge 6 includes a hollow upper body edge body 11 and a downward locking piece 12 extending downward from the lower surface of the upper body edge body 11.
The lower end portion 12a of the downward locking piece 12 is formed in the same shape as a latching portion 41 provided at one side end (lower end) of the panel piece 4 described later. Have been. Similarly, the lower waist edge 7 comprises a hollow lower waist edge body 13,
Upward locking piece 1 extending upward from the upper surface of lower waist body 13
4 and the upper end 14a of the upward locking piece 14 has the same shape as a hook receiving portion 31 provided on the other side end (upper end) of the panel piece 4 described later. Is formed. In this manner, the lower locking piece 12 and the upper locking piece 14 are provided on the upper body edge 6 and the lower body edge 7, respectively, and the panel pieces 4 described later are connected to each other in the same manner. ,
The panel piece 4 is directly attached to the upper body edge 6 and the lower body edge 7.

FIG. 3 is a cross-sectional view taken along the line BB of FIG. As shown in this figure, the vertical frames 8, 8 are composed of a hollow vertical frame main body 15,
It is provided on a side surface of the vertical frame body 15 and is integrally formed with a panel holding portion 16 that holds left and right side ends of the panel body 5. A concave portion 17 is provided at a corner on the outer end side of the vertical frame body 15.
The blindfold member 19 is mounted in the concave portion 17. The blindfold member 19 is made of a flexible material such as vinyl chloride, for example. As shown in FIG. 4, a mounting portion 19a having a substantially U-shaped cross section and one end of the mounting portion 19a are provided. And a fin 19b extending therefrom. The outer surface of the mounting portion 19a is formed in an uneven shape. When the blindfold member 19 is mounted in the concave portion 17 of the vertical frame main body 15, it engages with the unevenness formed inside the concave portion 17 and the blindfold member 19 is It is attached to the main body 15 in a retaining state.

On the other hand, the upper frame 6 and the lower frame 7 are laterally framed with respect to the vertical frames 8, 8 on which the blindfold members 19 are mounted. In this case, the vertical frame 8 is disposed slightly (distance d1) inside the fore edge of the upper frame 6 and the lower frame 7. That is, the fore edge of the upper frame 6 and the lower frame 7 is
Are slightly protruded from the outer ends of the vertical frames 8, and there is a gap between the adjacent vertical frames 8, 8. In order to fill this gap, the tips of the fins 19b of the blind members 19 of the vertical frames 8, 8 protrude outward from the fore ends of the upper frame 6 and the lower frame 7. For this reason, in the fence 1 in which the panels 2 and 2 are connected to each other, the fore ends of the upper frame 6 and the fore ends of the lower frame 7 abut, and
The fins 19b of the blindfold members 19, 19 are tightly bent together and completely cover the gap between the vertical frames 8, 8.
Therefore, when the vertical frames 8, 8 of the blindfold panels 2, 2 are connected to each other by abutting each other, light leakage from the gap can be reliably avoided. Also, the fore-edges of the upper frame 6 and the fore-edges of the lower frame 7 are directly butted,
Since the blindfold panels 2 and 2 are connected to each other, the size of the connected blindfold panels 2 and 2 in the finding direction can be accurately determined without being affected by the protrusion amount and flexibility of the blindfold portion 19a. .

Next, the panel piece 4 constituting the panel body 5 will be described with reference to FIGS. FIG.
As shown in (1), the panel piece 4 is integrally formed by a panel piece main body 25 and a hook receiving portion 31 and a hooking portion 41 formed at the upper and lower ends of the panel piece main body 25, respectively. On the panel piece main body 25, two bulging portions (upper bulging portion 21 and lower bulging portion 22) are formed up and down, and further, from the lower end of the lower bulging portion 22 to between the upper and lower bulging portions 21 and 22. An extension portion 24 is formed which is approximately the same length as the flat plate portion 23 of FIG. The panel piece main body 25 thus formed is
The strength in the expected direction is enhanced, and when viewed from the front of the panel body 5 configured by being connected in the vertical direction, the design is such that the bulging portions 21 and 22 appear at equal intervals.

The latch receiving portion 31 formed at the upper end of the upper bulging portion 21 has a pair of flange portions (upper flange portion 32, lower flange portion 33) and a web portion 34 connecting these.
Receiving section main body 35 having a substantially “U” -shaped cross section, a vertical wall piece 36 extending from the distal end of the lower flange section 33 toward the distal end of the upper flange section 32, and receiving from the distal end of the vertical wall piece 36. And a receiving-side detent piece 37 extending inside the main body 35. Further, between the upper flange portion 32 and the vertical wall piece 36, an insertion opening 38 for inserting the engaging portion 41 of another panel piece 4 is formed. On the other hand, the latching part 41 formed at the lower end of the extension part 24 has a pair of flange parts (a base flange part 42 and a distal flange part 43).
And a web portion 44 for connecting them, and has a substantially U-shaped cross section. An opening 45 is formed on the same side as the insertion opening 38. The web section 44
Length d3 in the connection direction (vertical direction) of the hooking portion 41 including
Is longer than the length d2 of the insertion opening 38 of the hook receiving portion 31.

The panel piece 4 thus constructed (hereinafter referred to as a panel piece 4)
FIG. 6 shows a state in which the panel pieces on the hook receiving portion side are referred to as “receiving panel pieces 4A” and the panel pieces on the hooking portion side are referred to as “hanging panel pieces 4B”. As shown in (1), the hook 41 of the hook panel piece 4B is inserted into the hook receiver 31 of the receiving panel piece 4A. In addition, the front end of the front end flange portion 43 of the hooking portion 41 is
In addition to contacting the first vertical wall piece 36, the tip of the upper flange portion 32 of the hook receiving portion 31 is in contact with the panel piece main body 25 (extending portion 24) near the base of the hook portion 41.

In order to attain such a connecting posture, first, the receiving panel piece 4A is held vertically, and the front flange portion 43 is hooked from the insertion opening 38 while the hooking panel piece 4B is laid down. Insert into the part 31. And
As shown in FIG. 7, the latch panel piece 4 </ b> B is rotated counterclockwise around the latch section 41 to completely insert the latch section 41 into the latch receiving section 31. In this case, the web portion 44 of the hooking portion 41 is inclined with respect to the opening surface of the insertion opening 38 while the hooking panel piece 4B is being rotated. Even if d3 is longer than the length d2 of the insertion opening in that direction, the insertion opening 38
Through this, the hook 41 can be easily inserted into the hook receiving portion 31.

In this way, a plurality of panel pieces 4 are sequentially connected to each other to form a panel body 5, and the upper end and the lower end thereof are connected to the upper frame 6 and the lower frame 7, respectively. The left and right side ends are screwed to the vertical frames 8 and 8 as appropriate with the part 23 or the extension part 24. Then, the cover 18 is attached so that the head of the screw cannot be seen from the front.

Next, the panel body 5 configured as described above
Will be described with reference to FIG. As shown in FIG. 8A, when receiving an external force from the opposite side of the insertion opening 38, the panel body 5 tends to bend in the direction of the external force. At this time, a bending force acts on the receiving panel piece 4A and the retaining panel piece 4B around the connecting portion. That is, the receiving panel piece 4A rotates clockwise around the P point or the Q point shown in FIG.
B tries to rotate counterclockwise. In this case, for example, when the two panel pieces 4A and 4B try to rotate around the point P, the tip flange 43 of the hooking portion 41 tries to move in the same direction (rightward) as the external force, but When the vertical wall piece 36 of the receiving portion 31 attempts to move in the opposite direction (left direction) to the external force, the rigidity at the connecting portion between the PQs resists the bending force. For this reason, if the rigidity between the PQs of the hanging panel pieces 4B is sufficiently large, the bending due to the rotation of the connecting portion hardly occurs. The same applies to the case where both panel pieces 4A and 4B are about to rotate around the point Q.

On the other hand, as shown in FIG. 8B, when receiving an external force from the insertion opening 38 side, the receiving panel piece 4A and the retaining panel piece 4B are slightly rotated downward and upward while rotating. , The end of the base flange 42 of the latch 41 is inscribed in the upper flange 32 of the latch receiver 31, and the distal flange 43 is locked by the receiving-side flexure piece 37. You. Since the hook 41 is locked in the hook receiving portion 31 at points R and S shown in FIG. 8B, the bending is suppressed before the connecting portion is largely bent. That is, when the above-mentioned external force acts on the panel piece main body 25 of both panel pieces 4A and 4B, the hooking portion 41 is moved to the upper flange portion 32 of the hook receiving portion 31 by the base flange portion 42.
Until they are inscribed at a point, they are slightly displaced in the hook receiving portion 31, and the displacement causes the connecting portion to be slightly bent.
The receiving-side flexure piece 37 attempts to push the front flange 43 downward. For this reason, the external force acts as a force for expanding the opening 45 of the hook receiving portion 41, but the rigidity of the connecting portion between the PQs resists the force, thereby suppressing the bending of the connecting portion. Is done. In addition, since the front flange 43 is hooked to the receiving-side flexure preventing piece, an extremely large external force acts on both panel pieces 4A and 4B, so that even if the insertion opening 38 is expanded, the retaining portion is formed. 41 does not come off the hook receiving portion 31.

As described above, in this embodiment, the upper and lower ends of the panel piece 4 are respectively provided with the latch receiving portions 3 having a predetermined shape.
1 and the latch portion 41, the panel body 5 formed by connecting a plurality of panel pieces 4 to each other
Even in the case where an external force is applied in the direction of finding, the bending of the connecting portion of the panel piece 4 can be extremely reduced, and the connecting portion can be reliably prevented from coming off. In the present embodiment, the case where the panel pieces 4 are connected in the vertical direction has been described.
Needless to say, the panel body 5 may be configured by connecting the panels in the left-right direction.

Next, a second embodiment of the present invention will be described with reference to FIG. The blindfold panel of the present embodiment includes:
A flexing piece is provided on a retaining portion of the retaining panel piece 4B. Specifically, the hook 41 of the panel piece 4B
A proximal flange portion 42 and a distal flange portion 43;
And a web portion 44 connecting the web portion 44 to the front end of the base flange portion 42.
6 is extended. The latch receiving portion 31 of the receiving panel piece 4A includes an upper flange portion 32 and a lower flange portion 33.
And a “V” -shaped web portion 34 connecting them, and a vertical wall piece 36 extending from the tip of the lower flange portion 33 toward the tip of the upper flange portion 32.

The panel pieces 4A, 4B thus configured
Are connected to each other, as in the first embodiment, after the distal end flange portion 43 of the hook portion 41 is inserted into the hook receiving portion 31 through the insertion opening 38, the hook panel piece 4B Is rotated to insert the hooking portion 41 into the hooking receiving portion 31.

When the panel body 5 formed by connecting the panel pieces 4 to each other as described above receives an external force from the direction of the finding, the following is performed. That is, the insertion opening 3
In the case where an external force is received from the side opposite to the side 8, as in the first embodiment, the distal end of the distal end flange portion 43 of the retaining portion 41 contacts the vertical wall piece 36 of the retaining receiving portion 31, and Since the distal end of the portion 32 is in contact with the panel main body 25 (extending portion 24) near the base of the latching portion 41, the connecting portion hardly bends.

On the other hand, as shown in FIG. 9B, when an external force is received from the insertion opening 38 side, the panel piece main bodies 25 of the receiving panel piece 4A and the retaining panel piece 4B move downward and upward, respectively. While being pulled, both panel pieces 4A and 4B tend to rotate around the tip of the locking-side flexure-stopping piece of the hooking part 41 inscribed in the upper flange part 32 of the hooking receiving part 31. By the action of this rotation, the distal end of the latching-side flexure stopper piece 46 acts to lift the receiving panel piece 4A upward, so that the tensile force acting on the panel piece main body 25 of both panel pieces 4A, 4B is reduced. It will be even larger. For this reason, the rigidity of the connecting portion is reduced by the two panel pieces 4A, 4A.
The bending of the connecting portion is suppressed against the tensile force acting on the panel piece main body 25 of B.

As described above, in the present embodiment, since the hook-side flexure piece extends further from the distal end portion of the base flange portion 42 into the hook receiving portion 31, the insertion opening 38 is provided.
Even when external force is applied from the side, the panel piece body 25
Therefore, the rigidity of the connecting portion resists the tensile force, and the bending of the connecting portion can be suppressed.

Next, a third embodiment of the present invention will be described with reference to FIG. The blindfold panel of the present embodiment has a circular connection portion between panel pieces. Specifically, the locking portion 61 of the locking panel piece 4B is
The outer shape is substantially circular in cross section, and is formed in a C-shaped cross section cut out in the chord direction. And this latching part 6
1 is a hook panel piece 4 from the outer surface via a bent portion 62.
B is formed so as to be continuous with the panel piece main body 25.
On the other hand, the hook receiving portion 51 has an inner peripheral surface formed in a complementary shape to the hooking portion 61, and has an inverted “C” -shaped cross section having an insertion opening 54 for inserting the hooking portion 61. Have been. The length d4 of the insertion opening 54 is
, That is, perpendicular to the chord of the notch 63, larger than the length d 5 passing through the center of the hook 61, and smaller than the outer diameter of the hook 61.

When connecting the thus formed hook panel piece 4B to the hook receiving portion 4A, first, the hook panel piece 4B is tilted with respect to the panel piece 4A, so that the hook panel 4A is inclined. The notch 63 of the portion 61 is inserted into the hook receiving portion 51 so that the chord direction of the notch 63 and the insertion direction of the notch 63 into the insertion opening 54 match. Next, the hook panel piece 4B is rotated about the hook portion 61 to bring the receiving panel 4A and the hook panel piece 4B into the connected posture.

The two panel pieces 4 connected in this manner
When A and 4B receive an external force from the expected direction, the following occurs. Panel piece body 2 of both panel pieces 4A, 4B
When 5 receives an external force from the insertion opening 54 side (the left side in FIG. 10), both panel pieces 4A and 4B tend to rotate around the connection portion. That is, the receiving panel piece 4A tries to rotate counterclockwise in the figure, and the retaining panel piece 4B tries to rotate clockwise in the figure. However, in this case, the bent portion 6 of the hook panel piece 4B is used.
2 abuts against one opening edge 53 of the hook receiving portion 51, and since the bent portion 62 functions as a rotation stopping portion for preventing rotation of the hooking portion 61 with respect to the hook receiving portion 51, both panel pieces are provided. 4A and 4B do not rotate at all. For this reason, the connection portion hardly bends. on the other hand,
When an external force is received from the side opposite to the insertion opening 54 (the right side in FIG. 10), since there is no detent portion as described above, although the connecting portion is bent by the rotation of both panel pieces 4A and 4B, both the portions are bent. As long as the panel pieces 4A and 4B do not rotate significantly, the hook receiving portion 61 does not come off from the hook receiving portion 51.

As described above, in this embodiment, both panel pieces 4A, 4A are subjected to an external force from the insertion opening 54 side.
B can be prevented from bending at the connecting portion, and
1 can be prevented from coming off the hook receiving portion 51. In addition, since the latching portion 61 is formed in a circular cross section, the connecting operation of the panel pieces 4 can be easily performed, and the connecting portion can be used as a screw hole.

In the above embodiment, the case where the blindfold panel is applied to the fence has been described.
It goes without saying that the blindfold panel of the present invention can also be applied to parts requiring blindfold in various buildings, such as balconies.

[0042]

As described above, according to the present invention,
A predetermined latching portion and a latching receiving portion are formed on both end portions of the panel piece, respectively. Even if an external force acts from a finding direction on a panel body formed by connecting such panel pieces to each other, the panel piece is connected. It is possible to reduce the bending at the portion, and it is possible to reliably prevent the connecting portion from being detached. Further, even when the panel bodies are connected to each other by abutting the vertical frames, it is possible to reliably avoid light leakage from the gap between the vertical frames.
