Abstract

PROBLEM TO BE SOLVED: To prevent mutually adjacent panels from slipping out of place in the longitudinal direction of a cylindrical part and prevent a fitted joint from getting out of position by arranging a jointing member of a first support part and a second support part fixed to the adjacent panel body, at the first hing of the connected panel bodies. SOLUTION: A guide roller protruded from a shutter curtain is guided by a guide rail to open/close the shutter and a first support part 11b is inserted in a cylindrical hole of the first connection piece 6b of a panel body. And at the same time, a second support part 11c integrally formed with the first support part 11b is fixed to the indoor face 3a of the panel body through a base body 11a. And hence, the positional shifting in the lengthwise direction of the cylindrical part of the mutual panel bodies is restricted because the base body 11a contacts the end of the panel body. And the outer diameter of a first support pin 11b is made larger than the opening width of a first opening to keep a jointed state of adjacent panel bodies through the joint member 11. In this way, this panel structure prevents mutual panels from slipping out of position and prevents mutual hinges from getting out of the fitting to provide two functions in a certain number of parts and bring out a high functional performance of the product.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a panel structure of a panel shutter provided in an opening of a building or a vehicle.

[0002]

2. Description of the Related Art Generally, in a panel shutter provided in an opening of a building or a vehicle, an adjacent panel body is used as a shutter curtain for opening and closing the opening. In some cases, the second cylindrical hinge portion is connected in a series by externally slidably fitting the second hinge portion. In such a hinged connection, one panel body is connected to the other panel body so as to be slidably fitted. However, in this case, in assembling the panel body, at least the panel body is connected. Since a large work space of twice the width in the left and right direction is required, there is a problem when assembling on a truck bed such as a truck shutter. Therefore, the first and second hinges are formed with long openings in the cylinder length direction, and the first hinge portion is bent at a preset angle (for example, approximately 90 degrees) of the panel body to open the second hinge portion. A configuration has been proposed in which the external fitting is slidably fitted by fitting into a part and extending and swinging. In this case, it is necessary to prevent displacement in the cylinder length direction. Conventionally, as shown in FIG. 11 (A), notches 15a are respectively formed at ends of the first and second hinge portions 15, 16 in the cylinder length direction. , 16a, and the notches 15a, 16a are provided with washers 17 having an outer diameter larger than the outer diameter of the first hinge portion 15 and smaller than the outer diameter of the second hinge portion.
Of FIG. 12 (B).
The notch 18a formed in the first hinge portion 18 as shown in FIG.
The first flange, which fits with the retaining flange 20a
It has been proposed to incorporate a pin 20 formed with a flange 20b for preventing slippage that abuts on the edge of the second hinge portions 18, 19, whereby the first and second hinges are provided in any case. Deviations in the cylinder length direction have been stopped by each other.

[0003]

By the way, the shutter curtain runs on a guide rail having a substantially inverted L-shape, such as a shutter curtain formed of such a panel body at an opening of a cargo bed of a vehicle. In such a case, an unexpected large load may be applied to the connecting portion of the panel body when a load or the like collides with the panel body running on the substantially inverted L-shaped portion. At this time, it is conceivable that the connection between the panel bodies by the first and second hinge portions is disconnected. In addition, such a situation can be further considered in a state where both hinge portions are worn out. As described above, in the conventional device, although consideration has been given to preventing displacement in the cylinder length direction, the panel body has been considered. Actually, no consideration has been given to avoid the hinge portions coming off, and there is a problem to be solved by the present invention.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been created with the object of solving these problems. When the large-diameter cylindrical second hinge portion is externally fitted to one hinge portion and connected in a series, the first and second hinge portions are formed with openings in the cylinder length direction, and the panel body is preset. In the panel shutter, the first hinge portion is fitted into the opening of the second hinge portion in an angled bending posture, and the panel body is fitted and connected by extending and swinging it. At the end of the panel body in the tube length direction, a first support portion whose tip is freely inserted into and removed from the tube hole of the first hinge portion, and the first support portion extends from the base end of the first support portion to the adjacent panel body side. Connecting member provided with a second support portion fixed to an adjacent panel body Provided, in which to perform the anti-removal of the displacement preventing the cylinder direction around the cylindrical length direction of the adjacent panel member comrades. And by doing this,
By providing one connecting member, not only the displacement of the adjacent panel bodies in the cylinder length direction but also the prevention of the fitting connection portion from coming off can be performed.

Next, an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment will be described with reference to FIGS. In the figure, reference numeral 1 denotes a panel shutter which is built at an opening of a box-type carrier of a freight carrier. A shutter curtain 2 constituting the panel shutter 1 has a plurality of panel bodies 3 which are connected to each other as described later. It is configured so as to swing (rotate) freely in a state in which the deviation of the direction and the detachment are prevented. The panel shutter 1 is opened and closed by a guide roller 4 projecting from both left and right ends of the panel body 3 being guided by a substantially inverted L-shaped guide rail 5 provided from both sides of the opening to the cargo bed ceiling. It is configured as an overslider type that operates, and the shutter curtain 2
Has a configuration in which the posture is changed between a vertical posture in which the opening is closed and a horizontal posture accommodated on the ceiling side, and both of these are conventional structures.

The panel body 3 is a hollow elongated body integrally formed of a metal extruded shape such as aluminum. The panel body 3c has indoor and outdoor surfaces 3a and 3b and has a panel thickness S. The first and second hinge portions 6 and 7 are arranged at the upper and lower ends and serve as connecting portions of the panel bodies 3. Further, the first hinge portion 6 at the upper end has an inclined piece 6a projecting from the upper end edge of the panel room outer surface 3b toward the interior side at an angle of approximately 45 degrees, and a projecting end edge of the inclined piece 6a. The first connecting piece 6b has a first opening 6c that is long in the tube length direction at a slightly upper position on the indoor side of the cylindrical shape having an outer diameter M. As a result, it is formed in a substantially C-shaped cross section. On the other hand, the second hinge portion 7 at the lower end is formed in a cylindrical shape having an inner diameter N larger than the outer diameter M of the first connecting piece 6b. A second opening 7a that is long in the cylinder length direction is opened, whereby the second connecting piece 7b is set to have a substantially C-shaped cross section. Here, the C shape of the second connecting piece 7b is an arc shape longer than a semicircle, and the opening width X of the second opening 7a is smaller than the outer diameter M of the first connecting piece 6b (X (M) is slightly larger than the radial distance Y (FIG. 4A) from the position of the first opening 6c to the outer peripheral position of the first connecting piece 6b facing the first opening 6c (X). Y) is set. That is, the first connecting piece 6b
Is that the distance Y is smaller than the outer diameter M by cutting out the cylindrical portion to form the first opening 6c (Y <
M). The first and second connecting pieces 6b, 7b are both set to be located between the panel thicknesses S.

Next, the connection of the adjacent panel bodies 3 will be described with reference to FIG. First, as shown by the imaginary line in FIG. 5 (A), the adjacent panel bodies 3 are set so that the interior surfaces 3a are set to an angle set in advance, approximately 90 degrees in the present embodiment, and face each other at this angle. The first and second connecting pieces 6b and 7b are brought close to and opposed to each other in the state (bending posture). In this state, the first opening 6c of the first connecting piece 6b is in a posture substantially orthogonal to the second opening 7a, and moves the first connecting piece 6b into the second opening 7a. Thus, the first connection piece 6b is set to be freely inserted into and removed from the second connection piece 7b. In other words, as shown in FIGS. 5B and 5C, the first connecting piece 6b is moved from the inside of the second opening 7a of the second connecting piece 7b to the first connecting piece 6b. When the panel body 3 on the second connecting piece 7b side is gradually swung upward, the first opening 6 of the first connecting piece 6b is
c enters the second connecting piece 7b, and FIG. 5 (D)
As shown in (2), when the adjacent panel bodies 3 are in the extended state, the connection is made in a state where the first connection piece 6b and the second connection piece 7b are prevented from coming off.

On the other hand, reference numeral 8 denotes a long cylindrical support member provided at each of the left and right ends of the panel body 3. The cylindrical hole of the support member 8 becomes a through hole 8a for a roller shaft, and The shaft portion 4a is set so as to be freely penetrated and supported. Further, a pair of engaging pieces 8b and 8c are formed in the outer cylinder surface of the support member 8 in the longitudinal direction so as to protrude, and these engaging pieces 8b and 8c are formed to protrude from the upper edge of the interior surface 3a of the panel body 3. A hook-shaped engagement receiving piece 3d whose tip is directed to the outdoor side and a hook-shaped engagement receiving piece 3e whose projected end is formed downward from the upper end edge of the outdoor surface 3b are slidably engaged with each other. Is set to In addition, a fixing through hole 8d penetrating in a state orthogonal to the roller shaft through hole 8a is formed in one cylindrical end of the support member 8. Further, the through hole 8a for the roller shaft is provided with the through hole 8a.
A hexagon nut 9 having an outer diameter substantially the same as a is set in a detent-like manner with the screw hole 9a communicating with the fixing through hole 8d. And the support member 8
In a state where the screw shaft 10 is slidably assembled from the left and right ends of the panel body 3, the screw shaft 10 is inserted through the fixing through hole 8 d facing the indoor side and screwed into the hexagon nut 9, thereby forming the screw shaft 10.
Of the panel body 3 presses the upper surface 3f connecting the indoor and exterior surfaces 3a and 3b of the panel body 3, whereby the support member 8 is fixed to the panel body 3.

For example, when the supporting member 8 is fixed to the left side, a supporting member 8 having a fixing through hole 8d formed at the right end of the cylinder is used. 8 is formed symmetrically with respect to the axis of the through hole 8a for the roller shaft in a state facing the through hole 8d for fixing, so that it is not left-right-handed. Further, the tip of the fixing screw shaft 10 is configured to fix the support member 8 to the panel body 3 by pressing the panel body upper surface 3f, and the screw shaft 10 strongly presses the panel body upper surface 3f. Even so, care is taken not to deform the interior and exterior surfaces 3a, 3b of the panel body 3. Furthermore, of the panel body engaging pieces 3d and 3e for slidingly engaging the support member 8, the indoor side engaging piece 3d is included.
The rainwater that has entered the indoor side will accumulate in d. A concave groove 3g is formed in the upper surface 3f of the panel body, and a concave portion 8e is formed in a portion of the support member 8 facing the concave groove 3g. A gap (rainwater guideway gap) is formed between 3 f and the support member 8. The rainwater collected in the panel body engaging piece 3d is guided to the gap, and is discharged from the end of the panel body 3 to the outside. The guidance of the rainwater by the gap is performed in the same manner even when the shutter curtain 2 is in the horizontal position. Therefore, the rain gutter F for receiving the guided rainwater follows the guide rail 5. It is formed as described above.

Reference numeral 11 denotes a connecting member in which the present invention is implemented. The connecting member 11 is set to be incorporated and set at both left and right ends of each connecting portion of the panel body 3.
A flat base member 11a constituting the connecting member 11
Is arranged at the end of the connecting portion so as to close the panel thickness S direction, and a pin whose tip projects toward the inside of the panel body 3 is provided at the lower end of the base body 11a. The base end of the first support portion (hinge pin) 11b is fixed. Here, the outer diameter of the first support portion 11b is smaller than the inner diameter of the first connecting piece 6b, but is larger than the opening width of the first opening 6c. It is set so as not to get out of one opening 6c. Further, from the upper end of the base body 11a, a flat plate-shaped second support portion 11c that is laminated on the panel body indoor surface 3a on the second connection piece 7b side is formed so as to protrude. Then, the connecting member 11 directs the base body 11a to the left and right ends of the connecting portion, and sets the first supporting portion 11b in a state of being inserted into the cylindrical hole of the first connecting piece 6b, thereby setting the second supporting portion. 1
1c is set so as to be arranged in parallel in a stacked manner at 12 clip nuts 12 attached to the panel body interior surface 3a on the second connection piece 7b side.

On the other hand, as described above, the clip nut 12 is disposed on the inner surface 3a of the panel body on the side of the second connecting piece 7b of the connecting portion, and the clip nut 12 is formed in a folded shape. The first and second surface portions 12a and 12b are composed of first and second surface portions 12a and 12b.
b is inserted from both left and right sides of the panel body indoor surface 3a to hold the indoor surface 3a in a sandwiched state. Then, the second support portion 11c of the connecting member 11

The left and right ends of the b and 7b are restricted from moving by the left and right base plates 11a. Thus, the panel body (lower panel body) 3 on the first connecting piece 6b side and the panel on the second connecting piece 7b side. The body (upper panel body) 3 is set so as to prevent a lateral displacement (cylinder length direction) of the bodies 3 from each other. Further, in the fixed state, the upper and lower panel bodies 3 are bent about not more than 90 degrees, so that the first connecting pieces 6b swing with respect to the first support portions 11b, so that the panel bodies 3 It is allowed to be fitted and connected without being disengaged, so that there is no problem. On the other hand, in a state where the first hinge portion 6 and the second hinge portion 7
Are separated from each other (movement from the fitted and connected state to a posture corresponding to FIG. 5A), the fitted connection is released. In this case, the connecting member 11 is Since the first support portion 11b of the panel body 3 does not fall out of the cylindrical hole of the first connection piece 6b and the second support portion 11c is fixed to the interior surface 3a of the upper panel body 3, the adjacent panel body 3 The posture (positional relationship) of the mating connection state between the first and second connecting pieces 6b, 7b is thereby restricted, whereby the separation movement is regulated, and the first and second connecting pieces 6b, 7b are disconnected from each other. It is set to be stopped.

In the embodiment of the present invention configured as described above, the shutter curtain 2 of the panel shutter 1
The opening and closing operation is performed in a state in which the guide rollers 4 projecting from both left and right end portions are guided by the guide rails 5 formed in a substantially inverted L-shape. The plurality of panel bodies 3 are connected to each other so that the first support portion 11b is freely inserted into and removed from the first connection piece 6b of the lower panel body 3 fitted and connected, and the base body 11a is connected to the lower body. Panel body 3 in which second support portion 11c integrated with first support portion 11b is located on the upper side
Is fixed to the indoor surface 3a. For this reason, the panel body 3
As described above, the positional deviation of the competitors in the cylinder length direction is restricted by the base body 11a hitting the left and right ends of the panel body 3. Moreover, in this case, as described above, the outer diameter of the first support pin 11b is
Since the opening width is larger than the opening width of the first connecting piece 6b, the connecting member 11 restricts the adjacent panel bodies 3 to the connected state, so that the first,
The second connecting pieces 6b and 7b are prevented from moving apart from each other, and the connecting fit of the panel bodies 3 does not come off. As a result, when such a structure is configured to be guided by a substantially inverted L-shaped guide rail 5 like a cargo bed of a vehicle, luggage hits the shutter curtain 2 at the L-shaped portion of the guide rail 5. Even in the case where the panel body 3 has been lost, there is no inconvenience that the panel bodies 3 come off.

As described above, the connecting member 11 embodying the present invention regulates the lateral displacement between adjacent panel bodies 3, but does not restrict only the lateral displacement as in the conventional one. The first and second hinges 6 and 7 can also be prevented from being disengaged from each other, and can be provided with two functions without increasing the number of parts, thereby achieving higher performance of the product. .

It should be noted that the present embodiment is not limited to the above-described embodiment, and that a shutter curtain having airtightness is required depending on the application. In this case, for example, FIG. As in the second and third embodiments shown in FIGS. 10 and 10, an elastically deformable airtight material 14 can be attached to one panel body 3. Even in these cases, there is no problem in providing the connecting members at the left and right ends of the connecting portions of the panel bodies 3, and the effects as in the first embodiment can be obtained.
