Description

  The present invention relates to an attachment structure for attaching a panel-like member such as a solar cell module to, for example, the roof of a box-type cargo bed of a truck.

  Truck loading platforms, which are vehicles for freight transportation, include an uncovered loading platform that opens upward, and a box-shaped loading platform that has a roof and is hermetically sealed. In recent years, box-type loading platforms that can prevent cargo damage due to wind and rain, simplify packaging, and prevent unloading have become widespread. Among the box-type loading platforms, for the purpose of rationalizing the loading and unloading work such as quick loading and unloading of cargo, a loading platform called a wing body that has a flip-up roof and can load and unload cargo from both sides and the rear is also frequently used. Yes.

  Recently, in the field of freight transportation, there has been a strong demand for the reduction of carbon dioxide emissions and the use of clean energy, and research and development for reducing the fuel consumption of vehicles has been actively conducted. Under such circumstances, development of a technology has been implemented in which a solar cell, which is attracting attention as clean energy, is installed on the roof of a vehicle, and the generated electric power is used as a power source for vehicle accessory devices. A box-type platform loaded on a large truck has a considerably large roof area. If a solar cell is installed here to generate electricity and store it in an on-vehicle battery, if the conditions such as the amount of sunlight are good, Electricity that provides the power necessary for the air conditioner that air-conditions the truck driver's cabin during a break is obtained. Accordingly, the operation of the vehicle engine can be stopped, and the fuel consumption can be reduced or the noise can be reduced.

  A solar cell is a rectangular panel-like solar cell module in which a large number of elements (cells) are connected in series and in parallel to obtain necessary voltages and currents. In a power generation facility using solar cells, usually, a plurality of solar cell modules are arranged in a plane and installed on a roof of a house, and the generated power of each solar cell module is collected and supplied to a customer. A plurality of solar cell modules are often attached to a roof or the like in such a manner that the peripheral portion thereof is held by an elongated rail-like frame, and such a solar cell module mounting method is disclosed in Japanese Patent Application Laid-Open No. 2007-2007 as an example. No. 165499.

The solar cell module shown in the above publication is installed on the roof of a house, and its mounting method will be described with reference to FIG.
As shown in FIG. 5 (a), this power generation facility basically has four rectangular solar cell modules 101 (one piece is cut in accordance with the shape of a roof, etc.) arranged in a plane. It is a thing. An elongate rail-like frame body 102 extending in parallel is placed on the eaves side, center portion, and ridge side of the roof, and a decorative board 103 is disposed adjacent to the eaves side frame body 102. The frame body 102 is an aluminum shape member (extrusion molding material) formed in the cross-sectional shape of FIG. 5B, and has a concave groove G into which the side portion of the solar cell module 101 is inserted at the upper part. ing. The frame body 102 is attached to the roofing material 105 via the fixing member 104. On the eaves side, the frame body 102 is slidably fitted to the fixing member 104 in combination with the decorative plate 103 (see FIG. 5 (c)). In the section, the two frame bodies 102 are slidably fitted to the fixing member 104 back to back (see FIG. 5D).

  That is, in the mounting method of the above publication, the frame 102 in which the concave groove G is formed is installed in parallel, and the distance between the concave grooves (between the end surfaces of the concave groove bottom) is set to the dimension of the corresponding side of the solar cell module. Is set approximately equal to. The solar cell module is attached with a certain gap between the solar cell module and the roof in a state where the upper and lower sides are inserted into the concave grooves G of the rail-shaped frame body 102. In addition, when a solar cell module is attached to the roof of a vehicle, it is also known to insert and fix the solar cell module in a concave groove of a frame body. As an example, Japanese Patent Application Laid-Open No. 11-240395 discloses a synthetic resin. A solar cell facility is disclosed in which a frame body made of an elastic material such as the above is attached to the roof of a vehicle by adhesion, a solar cell module is inserted into a concave groove of the frame body, and pressure contact is fixed using elasticity.

  Since the solar cell equipment is installed outdoors and is directly exposed to wind and rain or hail caused by temperature change or weather change, the solar cell module placed on the surface is easily damaged. In particular, the solar cell module installed on the roof of a truck's box-type cargo bed often comes into contact with the branches of trees while the truck is running, and it is damaged compared to fixed solar cell equipment for residential use. More opportunities to receive. Since a damaged solar cell module needs to be replaced, it is desirable that the mounting structure of the solar cell module be easy to mount and remove. On the other hand, the solar cell module placed on the roof of the truck-type cargo bed of the truck needs to be firmly attached so as not to drop off due to vibration during traveling.

The solar cell module mounting method of FIG. 5 is such that the rail-shaped frame is fixed in parallel to the upper and lower sides of the solar cell module, and the peripheral portion of the solar cell module is inserted into the concave groove formed in the frame. It is to hold. In such an attachment method, the distance between the concave grooves of the parallel frame (between the end faces of the concave groove bottoms) is set to be approximately equal to the dimension of the corresponding side of the solar cell module. For this reason, the solar cell module does not move in a direction orthogonal to the frame body and is prevented from being detached from the groove due to vibration or the like, but it is difficult to mount and remove one solar cell module. That is, in order to replace the solar cell module, it is necessary to remove the rail-shaped frame itself, and the solar cell module cannot be detached or attached alone.
By the way, there are various types of panel-like members similar to the solar cell module, and for example, a panel for advertisement may be attached to the side surface of a box-type cargo bed of a truck. An object of the present invention is to facilitate mounting and dismounting when mounting a general panel-shaped member, not limited to a solar cell module, and to firmly fix it to prevent dropping.

In view of the above-described problems, the present invention provides a panel-like member having one of the rail-like frames when one panel-like member such as a solar cell module is attached using two rail-like frames extending in parallel. And a cover member is fixed to the other side of the rail-shaped frame with a fastener so as to form a concave groove in the cross section, and a panel-like member is interposed between the two. The other end of this is sandwiched and held. That is, the present invention

A first rail-shaped frame body and a second rail-shaped frame body extending in parallel with each other are fixed to the planar substrate at a distance of a side length of the panel-shaped member,
The first rail-shaped frame is integrally formed with a concave groove in a cross section,
The second rail-shaped frame body is provided with a frame body and a cover member fixed to the frame body by a fastener, and a concave groove is formed in a cross section between the frame body and the cover member. Has been
One end of the panel-shaped member is inserted into the groove of the first rail-shaped frame, and the other end of the panel-shaped member is inserted into the frame body of the second rail-shaped frame. It is sandwiched and held between the cover members. ''
The panel-like member mounting structure is characterized by this.

  As described in claim 2, the frame main body and the cover member in the second rail-shaped frame are each provided with a stepped portion that forms a concave groove in a cross section when both are fixed. It is preferable that the mating surface of the frame body and the cover member is located at an intermediate portion of the thickness of the panel-like member.

  According to a third aspect of the present invention, in the first rail-shaped frame body in which the concave groove is integrally formed, one end portion of the panel-shaped member is easily provided on the wall portion of the inlet portion of the concave groove. It is preferable to form a recess for insertion into the.

  Further, as described in claim 4, the first rail-shaped frame and the frame main body and the cover member in the second rail-shaped frame are each formed by aluminum extrusion molding, and The first rail-shaped frame body and the frame body main body are, in a cross section, the same shape frame body fixing side fixed to the planar substrate, and the same extending in parallel with the frame body fixing side at a predetermined interval. It is preferable to provide a panel-like member holding side having a shape.

  As described in claim 5, a sealing material can be provided at an end of the panel-like member. In addition, as described in claim 6, the present invention is suitable as an attachment structure for attaching a solar cell module to a roof plate of a box-type cargo bed of a truck.

In attaching a panel-like member such as a solar cell module to a planar substrate such as a roof by two rail-like frames extending in parallel, in the present invention, two rail-like shapes each holding an end of the panel-like member. The structure of the frame is different. In other words, the first rail-shaped frame of the present invention is integrally formed with a concave groove in the cross section, whereas the second rail-shaped frame is fixed to the frame body by the fastener. And a recessed groove for holding the panel-like member is formed therebetween.
When attaching the panel-shaped member, one end of the panel-shaped member is inserted into the groove of the first rail-shaped frame, and the other end of the panel-shaped member is inserted into the frame body of the second rail-shaped frame. Place on top. In this state, when the cover member is fixed to the frame body by the fastener, the other end of the panel-like member is sandwiched and held between the two. Conversely, when removing the panel-like member, the fastener is removed and the cover member is separated from the frame body. If it carries out like this, it will become possible to take out a panel-shaped member from a rail-shaped frame, and it is not necessary to remove the frame main body of a 1st rail-shaped frame or a 2nd rail-shaped frame from a planar board | substrate in that case.

  In the mounting structure of the present invention, one end portion of the panel-like member can be easily mounted by simply inserting it into the concave groove formed integrally with the first rail-like frame body, and the cover member is simply removed. Thus, the panel-like member can be easily removed. The recessed groove for holding the panel-like member can set the overlapping portion with the panel-like member sufficiently long, so that even if the panel-like member receives vibration, it can be prevented from falling off from the rail-like frame. .

  In the invention of claim 2, the frame main body and the cover member in the second rail-shaped frame body are each provided with a stepped portion that forms a concave groove in the cross section when both are fixed, and the frame main body and The mating surface with the cover member is positioned at the middle part of the thickness of the panel-like member. In this way, when mounting the panel-like member, the end face of the panel-like member is abutted against the stepped portion of the frame body, and so to speak, it can be attached to the correct position in a “temporarily fixed” form. . Then, when the cover member is removed for taking out the panel-like member, a part of the panel-like member protrudes from the upper surface of the frame body, and it is easy to take out using a tool or the like.

According to a third aspect of the present invention, in order to easily insert the end portion of the panel-like member into the first rail-like frame body integrally formed with the concave groove, a recess is formed in the wall portion of the inlet portion of the concave groove. To form.
The width of the groove is set to be approximately the same as the thickness so as to securely hold the panel member, but when inserting the end of the panel member into the groove, the groove is usually slightly inclined from the oblique direction. Since it is inserted into the groove, the insertion work becomes difficult. When the recess is formed in the wall portion of the entrance portion of the recess groove as in the invention of claim 3, the recess becomes a “relief portion” of the corner portion of the panel-like member at the time of insertion work, and the panel smoothly A shaped member can be inserted.

  According to a fourth aspect of the present invention, the first rail-shaped frame body and the frame body main body and the cover member in the second rail-shaped frame body are each formed by aluminum extrusion molding, and the first rail-shaped frame body and the frame The body main body includes a frame fixing side having the same shape fixed to the planar substrate and a panel-shaped member holding side having the same shape extending in parallel with the frame fixing side at a predetermined interval in the cross section. It is what. Thereby, the frame main body of a 1st rail-shaped frame and a 2nd rail-shaped frame becomes a shape material containing a common shape in a cross section, and can attain commonality of the mold at the time of manufacture.

  In the invention of claim 5, a sealing material is provided at the end of the panel-like member, whereby the panel-like member can be firmly held in the concave groove.
