Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a stove equipped with a displacement regulating structure of a fitting portion, particularly a connecting member. In detail, when the plate-like body end portion of the metal plate forming the furnace main body and the connecting member is bent by bending, and when these bent portions are engaged and assembled to manufacture a furnace of a desired shape, The present invention relates to a stove equipped with a structure for regulating the displacement of the connecting member in the vertical direction.

(B) Problems to be Solved by Conventional Techniques and Inventions Conventionally, in order to form a metal plate into a cylindrical furnace, the metal plate is cut into a desired size and these cut ends are connected by welding or the like. Then, it is usually formed into a cylindrical body having a desired shape.

However, the welding method should be, for example, electric welding.
Gas welding or thermite welding must be carried out using welding machine tools, so the work involved is complicated, and there is the problem that extra cost is required to prepare welding tools and the like. there were.

Further, once the welding of the members is completed, even if these members are separated and reused, the members are destroyed and do not return to the original members, so that there is a problem that they cannot be reused.

Furthermore, the furnace is usually in the shape of a large cylinder, and each member is fixed and cannot be removed.Therefore, there is a problem in that the containers must be packed and transported one by one, leading to an increase in transportation costs. The industry's greatest concern was how to reduce the transportation cost of the stove.

Therefore, it has been considered that the furnace main body and the connecting member or the eaves are separately manufactured, and these are assembled to complete the furnace.

That is, the furnace is assembled by fitting the bent pieces formed at both ends of the opening of the furnace body and the bent pieces formed at both ends of the connecting member.

The furnace with this structure can be disassembled and transported to a distant place, which makes it possible to reduce transportation costs. However, the fitting portion of the furnace main body manufactured by the above method and the connecting member assembled to the furnace main body is displaced due to an external force, resulting in misalignment. For example, there has been a problem that the surface of the furnace main body and the upper end portion of the connecting portion are not aligned with each other, resulting in a defect in the product.

Therefore, various measures have been taken to prevent the displacement of the fitting portion of the bent piece. For example, there are the following known configurations.

If the fitting portion of the bent piece is crimped (JP-A-51-103863 and JP-A-51-147463), a locking piece is provided inside the bent portion of one of the metal plates in the curling process, A slit for receiving the locking piece is formed on the other metal plate, and the two metal plates are overlapped and curled (Japanese Patent Laid-Open No. 57-206533), or a metal plate forming a seam portion is formed. Uneven portions are formed on part or all of the surface, these uneven portions are fitted together, and the seam portion is filled with a sealant (Japanese Patent Laid-Open No. 58-20647), and the first folded piece and the first folded piece are mutually attached. In addition to the engagement, the insertion piece is engaged and inserted between the opposed second folded pieces to crimp the engagement portion to prevent displacement (Jitsuko Sho 51).
No. 134644), a structure of a handrail in which the engaged members are caulked with a punch and connected (Japanese Utility Model Publication No. 55-43632).

In the displacement prevention structure such as the bent piece of the fitting portion of the conventional example, since the related members are coupled in a state in which they cannot be disassembled or are difficult to disassemble, it is not easy to disassemble the related members and then reassemble them. There was a defect such as none.

Further, the furnace main body and the end of the eaves, which are respectively bent by bending, are fitted to each other, the bent end of the eave is extended upward to form a tongue piece, and the tongue piece is bent inside the furnace. By doing so, the upper end of the bent end of the furnace main body is abutted so as to cover it, the furnace main body and the eaves are made detachable, and the vertical displacement of the furnace main body and the end fitting portion of the eaves is regulated. There is also a configuration. (JP-A-64-15236).

However, the tongue formed to prevent displacement of the furnace main body and the eaves protrudes inward of the furnace, and if the tongue collides with another member during use, its shape will be deformed. Or other members on the tongue are caught,
There was a problem in that the eaves slipped out above the furnace main body together with the tongue piece, causing a problem in the fitting state with the furnace main body.

(C) Means for Solving Problems The present invention provides means for solving the above problems, the contents of which will be described below.

That is, in an assemblable furnace composed of a tubular furnace body having an opening on the side surface over the entire length, and a connecting member whose both side edges are connected to the opening so as to close the upper portion of the opening, The coupling is achieved by fitting a bent piece formed in the opening of the furnace body and a bent piece formed on both side edges of the key member, and further, the bent piece of the furnace body is The upper and lower sides of the connecting member, which is formed to be longer than the bending member of the connecting member, and accommodates a member for restricting vertical displacement of the connecting member in a space formed at the lower end of the bending member of the furnace body. It is a stove equipped with a directional displacement regulation mechanism.

(D) Operation The furnace according to the present invention can be assembled by disassembling it into the furnace body and the connecting member, and since the displacement restricting means of the connecting member is used, the fitting portion of the furnace main body and the connecting member is Since it regulates the displacement, it helps improve the performance of the furnace.

(E) Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

First, a displacement preventing mechanism of a fitting close contact portion of a conventional example will be described with reference to FIG. Bend 4 the first fitting member 2
Then, the bent portion 8 of the second fitting member 6 is fitted. At this time, in order to prevent the displacement of both fitting members 2 and 6, the end of the bent portion 8 of the second fitting member is further brought into contact with one side face f of the bent portion 4 of the first fitting member 2. As described above, the displacement of both fitting members 2 and 6 is prevented by the bending of the bending portion 10 and the friction between the bending portion 8 and the bending portion 8 which is in surface contact with the bending portion 10.

If this member fitting method is used for assembling the furnace, the furnace can prevent displacement at the fitting part, but since the fitting part is firmly assembled, it is possible to disassemble or assemble related parts. It is not easy to do and requires a lot of effort.

In FIG. 1, substantially cylindrical members W, W are arranged in the space of the bent portion 24 of the fitting member 22 for displacement regulation.
By fitting a bent portion (not shown) of another member into the second cutout portion 26, the fitting portions of both members can be prevented from being displaced from each other by the cylindrical members W, W.

FIG. 2 is a furnace manufactured using the displacement regulating member of FIG.
28 is a perspective view of 28. FIG. The bending piece 34 of the furnace main body 30 on the side of the connecting member 32 is fitted with the bending piece 33 of the connecting member 32. Since the length of the bent piece 33 is formed shorter than the bent piece 34 of the furnace, when the bent piece 33 of the connecting member 32 is fitted to the bent piece 34 of the furnace, A void C is formed near the lower end. If the cylindrical members W, W are inserted into the space C, the vertical position of the connecting member 32 can be regulated when the furnace body 30 and the connecting member 32 are fitted and in close contact with each other.

FIG. 3, FIG. 4 and FIG. 5 are reference examples of another displacement prevention mechanism other than the furnace. Bent portion provided on the first fitting member 36
38 is fitted with the bent portion 42 of the second fitting member 40. But second
A bent piece 43 divided into two by a cutting groove 44 is provided near the lower end of the bent portion 42 of the fitting member 40. The displacement prevention member 46 is fitted into the bent portion 42 formed by the second fitting member 40, and then the upper and lower portions thereof are formed into the curved portions 48 and 50. The upper and lower curved portions 48 and 50 of the displacement preventing member 46 are appropriately bent, and the lower curved portion 5
Since 0 is supported by the cutting groove 44, its longitudinal displacement is caused by the curved portion 50 in contact with the bent piece 43 and the curved portion 48 locked by the bent portion 38 of the first fitting member 36. It can be prevented.

Next, FIGS. 6 to 9 show another embodiment of the stove manufactured by utilizing the displacement regulating mechanism according to the present invention. The furnace main body Y and the joint X are fitted and closely contacted as shown in Fig. 9 (a), and the upper end of the furnace main body Y and the joint X are bent (Figs. 9 (b), (c), (See (d)), and the connection X is further provided at the upper end of the furnace main body Y.
The displacement of both members is completely prevented by the covering.

Next, FIGS. 10 to 14 show another reference embodiment other than the furnace. A rectangular box-shaped locking portion A is provided on the same surface as the bent portion 94 of the first fitting member 92. Second fitting member 96
The bent portion 98 is fitted and closely fitted to the bent portion 94 of the first fitting portion 92, and at the same time, the main body is positioned at a right angle to the first fitting portion 92, so that one side of the main body is box-shaped. It is placed in contact with one side of the stop A. Therefore, although the two fitting members 92 and 96 are arranged at right angles to each other, the displacement of the fitting portion is prevented by the box-shaped locking portion a.

(F) Effect As described above, since the displacement regulating means housed in the fitting portion of the furnace, which is removably assembled by the fitting and contacting method, restricts its displacement, the conventional tongue piece is provided. Since the tongue piece is hooked on another member like the displacement regulation mechanism, there is an effect that it is useful for improving the performance without causing structural deformation or other problems.

In addition, since the furnace is removably assembled, it is not necessary to package the furnace body and the connecting member separately as in the conventional example, but multiple furnace bodies and connecting portions can be packed separately and transported. Since it can be assembled at every other arrival place, it is useful for reducing transportation costs.
