2. Description of the Related Art There are two types of hoods of the type described above, which cover the open end of the air passage on the outdoor side and cover the open end of the air passage on the indoor side. The former is also called a weather cover, and its main function is to prevent intrusion of wind and rain from the outdoor opening edge. The latter is a kitchen hood, etc., whose main function is to collect rising oil smoke and guide it to the open end. Although they have different functions, they are almost the same in outer shape, and most of them have a hollow hood type having a top plate part and a left and right side plate part that are continuous from the top face to the front face or in an arc surface.

For example, Japanese Unexamined Patent Publication No. 6-11165 discloses a weather cover composed of a curved top plate 101, fan-shaped left and right side plates 102, and an oil receiver 103 as shown in FIG. Top plate 101, side plate 102, and oil receiver 1
03, each has a mounting flange 104 formed on its mounting side, and is mounted so as to surround the open end of the air passage by this mounting flange 104. That is, the exhaust air from the air passage is exhausted into the weather cover through the open end, and is exhausted outdoors through the open end at the lower part of the weather cover. Except for small ones, most of such hoods are made of sheet metal, and each part is connected by screw fastening, welding or the like to form a hood body.

BEST MODE FOR CARRYING OUT THE INVENTION

First Embodiment of the Invention 1 to 7 show the hood of the first embodiment. As shown in FIG. 7, this hood is a weather cover that covers the open end 2 on the outdoor side of the air passage that opens to the wall surface 1, is divided into several members, and is assembled and used on site. That is, this weather cover is composed of left and right side plate parts 3, 4, a top plate part 5, and a draining member 6, as shown in FIG. Each of these three members is formed of a thin metal plate having elasticity such as a steel plate.

The left and right side plate portions 3 and 4 are functional members for closing the left and right sides of the open end 2 of the air passage opening in the wall surface 1, and have a substantially fan shape in plan view. On the opening end 2 side of each of the side plate portions 3 and 4, a mounting flange 7 that is abutted on the left and right side edges of the opening end 2 and screwed to the air passage side is formed by bending. Each side plate 3,
The upper part of 4 is connected to the front part in an arc shape, and inwardly facing flanges 8 are bent to form joint surfaces 9 (see FIG. 5). Fitting holes 10 are provided in the joint surface 9 at intervals from the upper portion to the front portion. Further, an inward mounting surface 11 is bent and formed at a substantially right angle on the side of the mounting flange 7 at the bottom of each side plate portion 3, 4. The mounting flange 7 is formed slightly longer than the vertical dimension of the base portion,
The upper and lower ends thereof project from the upper and lower ends of the base portion.

The top plate portion 5 is a functional member that extends from the upper portion between the left and right side plate portions 3 and 4 to the front portion and covers the upper side and the front side of the opening end 2. Basically, the side plate portions 3 and 4 are provided. A flat plate having a length substantially equal to the overall length of the joint surface 9 and a width substantially equal to the dimension of the opening end 2 in the left and right directions,
It can be easily elastically bent. A mounting flange 12 is also bent at one end of the top plate portion 5 so as to be brought into contact with the upper edge of the opening end 2 and screwed to the air passage side. At the opposite left and right end edges of the top plate portion 5 on the long side, the joint surface 9 of the side plate portions 3 and 4 is formed.
A plurality of claws 13 corresponding to one to one are bent and formed inwardly in the fitting hole 10 formed in (1) (see FIG. 5). The claw 13 and the fitting holes 10 on the side plate portions 3 and 4 form a locking structure during assembly. The claw 13 has a constriction 14 at the base as shown in FIG. 2 and can be easily bent.
The tip end side of the claw 13 has a width smaller than that of the base side and has an arc 15 for facilitating fitting into the fitting hole 10, and is bent slightly inward with respect to the base side. At the left and right edges of the portion of the top plate 5 that is close to the mounting flange 12, there are flanges 16 that face inward slightly outward from the positions of the claws 13.
Is partially bent. The claw 13 of this portion is formed on the separate member 17, and the separate member 1 formed in an angle shape.
The claws 13 are formed by fixing 7 together. The free edge of the top plate 5 opposite to the mounting flange 12 is bent inward in a hook shape as a hook 18 that can be hooked on the tips of the joint surfaces 9 of the left and right side plates 3, 4. It is rare.

The draining member 6 is a functional member that prevents water from entering the opening end 2 side at the lower edge of the opening end 2 and prevents dirt from adhering to the wall surface 1 below the opening end 2. Is a configuration in which a front flange 19 that projects obliquely downward is brought into contact with the lower edge of the opening end 2 and a mounting flange 20 that is screwed to the air passage side is formed. This Embodiment 1 has a mounting flange 2
On the front side of 0, a narrow flat portion 21 whose both ends contact the mounting surfaces 11 of the left and right side plate portions 3, 4 is provided. A locking structure having the same structure as the locking structure described above is also provided at both ends of the mounting surface 11 and the flat surface portion 21. That is, the flat part 21 on the side of the draining member 6 is formed with the upwardly facing claws 13 bendable at both ends thereof, and the fitting surface 10 is formed with the fitting holes 10 into which the claws 13 can be fitted.

As shown in FIG. 4, the weather cover having the above-mentioned structure is provided with the left and right side plate portions 3, 4 arranged side by side on the flat top plate portion 5 and the draining member 6 placed on the side plate portions 3, 4. It can be packaged in the packing box 22. Since the top plate 5 is a flat plate and the side plate parts 3 and 4 are also substantially flat plates, the packing volume in this packed state is flat and has a size slightly larger than the width of the mounting flanges 7, 12, 20 and is small and not bulky.
Therefore, less packaging material is required, and storage space and loading efficiency in transportation are significantly improved.

The disassembled weather cover can be easily assembled in the field without tools. That is, FIG.
As shown in FIG. 3, for example, the unpacked packaging box 22 is formed into a flat plate shape, and the flat plate-shaped top plate portion 5 is placed on the top side, and then the joint surface 9 of one side plate portion 3 is set inside. The claws 13 of the top plate portion 5 are fitted into the fitting holes 10 one by one from the mounting flange 12 side, and the claws 13 are sequentially bent inward (see FIGS. 2 and 3). At this time, the tip of the claw 13 is tapered and the arc 1
Since the shape is five, fitting into the fitting hole 10 is easy without being caught. Further, the fitted claw 13 is bent inward at the tip end side, and a gap 23 is formed between the claw 13 and the side plate portions 3 and 4 as shown in FIG. It can be bent so that the inner surface of the top plate portion 5 is firmly in close contact.

By such an operation, the end edges of one side plate portion 3 and the top plate portion 5 are locked from the mounting flanges 7 and 12 side to appropriate positions, and the other side plate portion 4 is operated in the same manner as described above. It is locked to the other edge of the top plate portion 5. Some claws left after that 1
3 is fitted into the fitting holes 10 of the left and right side plate portions 3, 4 and bent,
When the hooking portion 18 at the end of the top plate portion 5 is hooked on the end edges of the side plate portions 3 and 4 and stopped, the assembly of the top plate portion 5 and the side plate portions 3 and 4 is completed. The top plate portion 5 comes into close contact with the joint surface 9 as the claw 13 is bent, elastically bends along the surface profile of the joint surface 9, and is assembled into the form shown in FIG. 6 in which the upper surface and the front surface are continuous in an arc shape. . After this, the draining member 6 is hooked at both ends on the mounting surfaces 11 of the left and right side plate portions 3 and 4, and the claw 13 and the fitting hole 10 are aligned as shown in FIG. 6 to bend the claw 13 as described above. After installation, all the assembly work is completed and the weather cover is completed.

In the finished weather cover, the ends of the mounting flange 12 of the top plate 5 and the ends of the mounting flange 20 of the draining member 6 overlap with the ends of the mounting flanges 7 of the left and right side plates 3, 4 from above. As shown in FIG. 7, it can be mounted by screwing it onto a wooden frame or the like of the open end 2 using the mounting holes 24 formed at four corners which overlap each other. By attaching the mounting flanges 7, 12, 20 to each other and screwing the mounting flanges 7, 12, the mounting state of the weather cover becomes stable. Since the flanges 16 formed on the left and right edge portions of the top plate portion 5 on the side of the mounting flange 12 are in close contact with the outer surfaces of the side plate portions 3 and 4 from the outside, intrusion of rainwater is prevented. Although the front side locking structure portion is not covered by the flange 16, it has a vertical surface configuration that draws an arc and is located away from the opening end 2 to the front, so the rainproof function is not so necessary. .

In addition to its original function, the draining member 6 connects the left and right side plate parts 3 and 4 at the lower part to improve the structural stability of the weather cover, but as a hood, the top plate part 5 is used. There are also those that can function even with the configuration of only the left and right side plate portions 3, 4. There is also a hood that separately prepares a mounting structure for the mounting flanges 7, 12, 20 and mounts them. In such a type of hood, the top plate 5 and the side plate 3,
The flatness of No. 4 is higher, and the packaging volume is further reduced.

Embodiment 2 of the Invention The weather cover of the second embodiment shown in FIGS. 8, 9 and 10 is also the first embodiment.
It has basically the same structure as the weather cover shown in.
In the second embodiment, the locking structure is devised to make the locking operation easier. Therefore,
The same reference numerals used in the first embodiment are used for the same parts as those of the first embodiment other than the locking structure, and the description thereof will be omitted.

As shown in FIGS. 9 and 10, this weather cover has a plurality of locking structures for connecting the top plate portion 5 and the side plate portions 3 and 4 which are formed by bending inward at the left and right edges of the top plate portion 5. The claws 25 and a plurality of fitting holes 10 into which the claws 25 formed on the joint surface 9 at positions corresponding to the claws 25 can be fitted. An elastically deformable upward elastic locking piece 26, which is engaged with the fitting hole 10 and has a free end that engages with the edge of the fitting hole 10 to prevent the claw 25 from coming off, is cut and raised inward at the center. On the other hand, a protrusion 27 is formed at the center of the inner edge of the fitting hole 10 to which the free end of the elastic locking piece 26 of the claw 25 abuts. The locking structure between the draining member 6 and each of the side plate portions 3 and 4 is also configured by the claw 25 and the fitting hole 10 having the above-described configuration. The other configuration is the same as that of the first embodiment.

Also in this second embodiment, the form of the disassembled state is the same as that of the first embodiment except for the locking structure, and the packaging volume is also flat and small. In assembly, the claws 25 are sequentially fitted from the mounting flange 12 side to the fitting hole 1
If each of them is fitted into 0, they can be assembled into a completed form as in the first embodiment. Fitting hole 1 for claw 25
In fitting into 0, the elastic locking piece 26 enters the fitting hole 10 from the base side thereof, is pressed against the protruding portion 27 and is pushed outward into the fitting hole 10 while elastically deforming outward. The elastic locking piece 26 that has slipped out to the back of the fitting hole 10 immediately springs back, and the free end hits the protruding portion 27 of the fitting hole 10 on the back side, and fulfills the retaining function. That is, in the second embodiment, the top plate 5, the side plates 3 and 4, and the draining member 6 can be connected and assembled by a simple and easy operation of fitting the claw 25, which makes the assembling operation difficult. Easier to do. Other functions and advantages are described in the first embodiment.
The description is omitted because it is the same as.

Third Embodiment of the Invention The weather cover of the third embodiment shown in FIGS. 11 and 12 is a combination of the locking structure shown in the first embodiment and the locking structure shown in the second embodiment. This is the same as modes 1 and 2. Therefore, the same reference numerals used in the first and second embodiments are used for the same parts as those in the first and second embodiments, and the description thereof will be omitted.

The spring-back of the elastic locking piece 26 connecting the members to each other has a functionally lower problem than the connection of the members by bending the claws 13, but the holding force of the connection is slightly lower. In the weather cover, the front portion of the top plate portion 5 is likely to receive an external force due to a collision such as an external wind or a ball, and if the holding force for connection of this portion is increased, the top plate portion 5 may come off due to such external force. This can be prevented and the structural stability can be improved. That is, in the third embodiment, the bendable claw 13 is arranged on the front surface side of the top plate portion 5. Since the external force is not applied to the top plate 5 on the upper side, the elastic locking piece 2
A claw 25 with 6 is arranged. Of course, two types of claws 13 and 25 may be mixed in the entire area of the edge. The other configurations, functions, and advantages are the same as those of the first and second embodiments, and therefore description thereof will be omitted.

Embodiment 4 of the Invention 13, 14, 15
The weather cover of the fourth embodiment shown in FIG.
The flange 16 formed by bending a part of the edge of the top plate portion 5 shown in (3) is formed over the entire length of the edge of the top plate portion 5 to provide the entire rainproof function. Regarding the locking structure, the claws 13 and 25 shown in the first and second embodiments are used alone or in combination. However, the flange 16 is the top plate portion 5 in a series.
Since it will not turn, it is divided at several places. Further, since the claws 13 and 25 cannot be associated with the fitting hole 10 unless they are located inside the flange 16, the angle-type separate member 1 in which the claws 13 and 25 are formed is not formed integrally.
It is provided by fixing 7 to the edge of the top plate portion 5. However, if the claws 13 and 25 are formed at the cut portions of the flange 16 as shown in FIG. 14, the claws 13 and 25 can be integrally formed on the top plate portion 5, and the separate member 17 is not required. . The left and right side plate portions 3 and 4 are formed with a face having a width corresponding to the width of the flange 16 obtained by dividing the upper surface, the front surface, and the joint surface, not the arc shape. The rest of the configuration is the same as in the first, second, and third embodiments, so description thereof will be omitted.

Also in the fourth embodiment, the form of the disassembled state is the same as that of the first embodiment except for the flange 16 portion, and the packaging volume is also flat and small. In assembling, if the claws 13 and 25 are sequentially fitted into the fitting holes 10 from the side of the mounting flange 7, they can be assembled similarly to the first embodiment to a completed form. However, since the top plate portion 5 is provided with the flange 16, the top plate portion 5
Is not a circular arc surface but a rectangular shape in which a flat surface is continuous for each width of the flange 16 as illustrated. In the completed form, as shown in FIGS. 13 and 14, the flange 16 comes into contact with the outer side surfaces of the side plate portions 3 and 4 from the upper portion to the front portion from the outside and closes the portion, so that the waterproof function is excellent. The other functions and advantages are the same as those in the first and second embodiments, and therefore the description thereof will be omitted.

Embodiment 5 of the Invention As described in the third embodiment, in the weather cover, the front portion of the top plate portion 5 is likely to be subjected to external force due to collision of outside wind or balls. In the fifth embodiment, the top plate portion 5 is also affected by such an external force.
The end of the is prevented from coming off, and the structural stability is enhanced. The configuration other than this is the same as the previous embodiments, and the same configurations as those are denoted by the same reference numerals and the description thereof is omitted.

As shown in FIG. 16, this weather cover has a hooking piece which can be fitted to the notches 28 formed at the front ends of the joint surfaces 9 of the side plate parts 3 and 4 on the left and right of the front end part of the top plate part 5. 29 is bent inward, and each hooking piece 29 is provided with an upward hook 30 that is hooked on the notch 28. The configuration other than this is the same as each of the above-described embodiments.

Also in this fifth embodiment, the form of the disassembled state is almost the same as that of the above-mentioned respective embodiments, and the packaging volume thereof is also flat and small. Even when assembled, the top plate 5 and the side plates 3 and 4 are basically connected in the same manner as described in the first embodiment, but the connecting direction is not from the mounting flanges 7 and 12 side, It will be performed from the front end side of the top plate portion 5. That is, the hook 30 of the hooking piece 29 on the top plate portion 5 side is hooked to the notch 28 of the side plate portions 3 and 4 for positioning, and the connecting operation of the locking structure is sequentially started from this point toward the mounting flange 12 side. Then assemble. This allows
The front end of the top plate portion 5 is firmly fixed so that the top plate portion 5 does not come off due to the collision of external wind or an object. The other functions and advantages are the same as those of the first and second embodiments and so the description thereof will be omitted.

Sixth Embodiment of the Invention In this sixth embodiment, as shown in FIG. 17, the top plate portion 5 in each of the above embodiments is
The lengths of the claws 13 and the claws 25 formed on the left and right edges of the claw 13 are longer on the side that is the starting point of the connecting operation. Except for the part related to this configuration, it is the same as each of the above-described embodiments, so the same reference numerals are used and description thereof is omitted.

The top plate 5 is initially flat and assembled into an arc shape due to elastic deflection, but if all the pawls 13 and 25 have the same length, they are sequentially positioned and lose their freedom. Therefore, as it goes to the terminal side, fitting into the fitting hole 10 becomes more difficult. By making the side that becomes the starting point of the connecting operation longer and making the claws 13 and 25 on the terminal side shorter,
As shown in FIG. 17, the difficulty of fitting the claws 13 and 25 into the fitting hole 10 can be alleviated, and the assembly becomes easier. The other functions and advantages are the same as those of the above-described respective embodiments, and the description thereof will be omitted.

Seventh Embodiment of the Invention In the seventh embodiment, as shown in FIGS. 18 and 19, the locking structure is configured by the claw 25 provided with the elastic locking piece 26 shown in the second and third embodiments, but the joint surface 9 and the top plate portion are It is a device to improve the adhesion with No. 5 and eliminate rattling. Since the other configurations are the same as those in the second and third embodiments described above, the same reference numerals are used and the description thereof is omitted.

That is, the side plate portions 3 and 4 shown in the second embodiment.
The pressing piece 31 for pressing the elastic locking piece 26 of the claw 25 fitted in the fitting hole 10 formed in the joining surface 9 of the outer side is formed. The pressing piece 31 is formed by cutting the center of a protrusion 27 formed at the center of the inner edge of the fitting hole 10 and bending it downward in a tongue shape. The elastic locking piece 26 that elastically returns by the fitting of the claw 25 into the fitting hole 10 and performs a retaining function acts as an elastic force that pushes the pressing piece 31 inward as shown in FIG. Upon receiving the reaction force from the piece 31, the piece 31 is pushed outward. That is, the left and right edge portions of the top plate portion 5 and the corner portions of the joint surface 9 of the left and right side plate portions 3 and 4 are brought into close contact with each other by the pressing force, and an assembled state without rattling can be obtained.
