Description

The present invention relates to a type of fan (floor-mounted fan) that is useful as a simple, portable fan for use in storage rooms or storage areas of livestock sheds, farm facilities, or other products, plants, goods, etc., and to a method for assembling the fan.

Conventionally, this type of blower (conventional blower) is configured as shown in the conventional example in Fig. 13 and Fig. 14 by fixing the first and second standpipes (100, 101) facing each other via screws (102, 103) to the upper ends (100a, 101a) of the first and second standpipes (100, 101), and supporting and fixing the blower (104) by this fixing (102a, 103a). In addition, the first and second staypipes (105, 106) are fastened to the inside between the first and second standpipes (100, 101). In addition, the first and second mounting plates (107, 108) are fixed between the first and second standpipes (100, 101), respectively. The lower end stoppers (109, 110) of the fan part of the blower are inserted and supported (111, 112) in the holes of the first and second mounting plates (107, 108). In the figure, (113, 114) indicate wheels.

This conventional blower is configured to have first and second standpipes (100, 101) facing each other and assembled together. This creates problems and difficulties in verifying the time, sequence, and/or procedure involved in assembly. In other words, there are problems to be solved in terms of facilitating and simplifying the assembly of the blower and/or the verification of the assembly.

That is, we propose a blower with a structure that helps to facilitate and simplify the assembly of the blower and/or the assembly check, and a method of assembling the blower.

In the prior art, JP 2004-052709 A (Document 1) describes an invention for a "large agricultural blower that is suspended from a livestock or poultry house and blows air inside the livestock or poultry house," but this has a different structure from the floor-standing blower intended by the present invention. Also, in the invention of Jitsuzen S63-042893 A (Document 2), "a hanging/floor-standing blower in which a cylindrical leg fixing part is welded perpendicular to the surface of the base, three triangular stands are fixed to this, and the blower body is supported via a mounting stand," but this has a different structure from the floor-standing blower intended by the present invention.

In addition, there are design registrations such as Design Registration No. 1209284 (Reference 3) and Design Registration No. 1287813 (Reference 4), but these have a different structure from the present invention.

JP 2004-052709 A Publication No. 63-042893 Design Registration No. 1209284 Design Registration No. 1287813

Therefore, there is no disclosure of any structure that would facilitate or simplify the assembly and/or inspection of the floor-standing fan described above. Also, there is no disclosure of a method for assembling this fan.

Below, we explain each preferred embodiment of the present invention.

First, the stand A (frame), which is the basis and main part of the present invention, will be described with reference to Figures 8 to 11. Reference numerals in the figures are used to indicate the main parts.

The detailed structure of the stand section A will be described later, but the framework is made up of (a) first and second stand pipes 1 and 2 of triangular shape (inverted V shape) provided on one of the four opposing faces X of the stand section A, and (b) first and second stay pipes 3 and 4 provided on the other opposing face Y and supported with a gap B between the first and second stand pipes 1 and 2.

A first mounting plate 5 having bent piece portions 5a, 5b is provided at both bottom portions 1-1, 1-2 of the first standpipe 1. Below both bottom portions 1-1, 1-2 of the first standpipe 1 are both hanging portions 1-3, 1-4, and the upper end of the first standpipe 1 is the bent connecting portion 1-5.

A second mounting plate 6 having bent piece portions 6a, 6b is provided at both bottom portions 2-1, 2-2 of the second standpipe 2. Below both bottom portions 2-1, 2-2 of the second standpipe 2 are both hanging portions 2-3, 2-4, and the upper end of the second standpipe 2 is the bent connecting portion 2-5. However, the hanging portions 2-3, 2-4 are shorter than the hanging portions 1-3, 1-4 described above.

As shown in FIG. 5, the first and first extension parts 1-7 and 1-70 and the second and second extension parts 2-7 and 2-70 are formed at the lower ends of the bent piece parts 5a and 5b and the bent piece parts 6a and 6b, respectively, and the both end parts 3a and 3b and both end parts 4a and 4b in the longitudinal direction of the first and second stay pipes 3 and 4 are supported by the first and first extension parts and the second and second extension parts 1-7 and 1-70 and 2-7 and 2-70, respectively. The first and second stay pipes 3 and 4 are attached to the outside of the bent piece parts 5a and 5b of the first stand pipe 1 and to the outside of the bent piece parts 6a and 6b of the second stand pipe 2, respectively.

With the above steps, the pair of first and second stay pipes 3 and 4 are supported between the pair of first and second stand pipes 1 and 2, and the stand section A shown in Figures 8 to 11 is assembled and formed.

Then, a pair of first and second stay pipes 3 and 4 are supported between the pair of first and second stand pipes 1 and 2, and this state forms, for example, the assembly of stand section A shown in Figures 9-12 and the main body section for mounting the blower 20.

In the figure, reference numerals 10 to 14 denote fasteners for attaching the pair of first and second stay pipes 3 and 4 to the first and first extension portions and the second and second extension portions 1-7 and 1-70, and 2-7 and 2-70.

In addition, 1-6a and 1-6b in the figure indicate the inclined portions of the first standpipe 1, and 2-6a and 2-6b in the figure indicate the inclined portions of the second standpipe 2, and 1-6a and 1-6b and 2-6a and 2-6b in the figure are the portions that expand into an inverted V shape from the bent connecting portions 1-5 and 2-5, respectively.

The structure of the stand A described above and the assembly method described, illustrated, or described below are preferred examples of the present invention and are not limiting in any way.

Wheels 7 and 8 are pivotally supported on the inside of the short hanging parts 2-3 and 2-4, and the installation surface of the wheels 7 and 8 is the same as the installation surface of the long hanging parts 1-3 and 1-4. In other words, the blower 20 is installed horizontally, as shown in the figures showing the installation state.

Next, as shown in Figures 1 to 7, to attach the blower 20 to the stand section A, the first and second screws 22a, 22b are inserted into holes provided at both upper ends 21a, 21b of the frame 21 and holes provided at the bent and connected section 1-5 of the first standpipe 1 and the bent and connected section 2-5 of the second standpipe 2, respectively, and screwed in place. This procedure attaches the upper section 20a of the blower 20 to the stand section A.

The first and second guide pins 24a, 24b provided on both lower ends 21c, 21d of the frame 21 are inserted and locked into the notched holes 23a, 23b of the first and second mounting plates 5, 6. This allows both lower ends 21c, 21d of the frame 21 to be locked to the stand A and movably attached. Therefore, both lower ends 21c, 21d are guided into the notched holes 23a, 23b. In other words, the vertical air blowing direction of the blower 20 can be freely adjusted. The blower 20 is equipped with a fan, a motor, a guard, and other devices.

In the figure, 30 is a handle pipe that is provided across both inclined portions 1-6a, 1-6b of the first standpipe 1, and is formed on the opposite side of the second standpipe 2 to which the wheels 7, 8 are attached, and extended outside both inclined portions 1-6a, 1-6b of the first standpipe 1 (gripping area). By grasping this handle pipe 30 (gripping area) and lifting both hanging portions 1-3, 1-4 of the first standpipe 1, it is possible to move freely using the wheels 7, 8. It has the characteristic of being able to move to a desired location and deliver wind to a desired place. In addition, this blower 20 can contribute to easy and quick assembly, installation, and/or disassembly and removal of the stand part A and the blower 20 by removing the first and second screws 22a, 22b and the first and second guide pins 24a, 24b.

Figure 13 shows a structure in which the first and second stay pipes 3 and 4 are attached to the inside of the first and second stand pipes 1 and 2, which is an example shown in Figure 12. In this example, multiple mounting fixtures 31 are used, but this is just one example.

Figure 14 shows another example of the first and second standpipes 1 and 2, in which the length of either the first and/or second standpipe 2 (1-1 and/or 2-1 leg-length form) is adjusted to a large or small length, and the ground surface where the wheels 7 and 8 come into contact with the ground is also adjusted to the 1-1 and/or 2-1 leg-length form. With this structure, the direction of the air blown by the blower 20 can be selected in many directions. As mentioned above, this can be useful for utilizing the air, securing hot air and air cooling, or improving the efficiency of work and quality control, for example, in livestock sheds, agricultural facilities, or storage rooms and storage areas for other products, plants, goods, etc. As a rule, the length adjustments of the first and second standpipes 1 and 2 and/or the hanging parts 2-3 and 2-4 of the wheels 7 and 8 are made simultaneously, but a structure in which they are lengthened or shortened individually is also possible. In addition, another idea for the example in FIG. 15, which will be described later, is to use an insertion/removal mechanism or other length adjustment mechanism to achieve the length adjustment structure (height adjustment), and this is a mechanism that can be easily used with an adjustment tool and insertion/removal movements. It is also possible to use a folding structure, a removable attachment structure, etc.

In Figure 14 (a), the length of both hanging portions 1-3 and 1-4 of the first standpipe 1 is greater than the length of hanging portions 2-3 and 2-4. In other words, the wheels 7 and 8 side are in a low position, and the wind is in a relationship where the front side Z1 is in a high position and the rear side Z2 is in a low position in Figure 14. A structure with the opposite relationship is also possible, as shown in Figure 14 (b). In contrast, the other hanging portion 1-3 > hanging portion 1-4, or hanging portion 1-3 < hanging portion 1-4 are also possible.

Figure 16 is a perspective view showing an example of the moving state of the blower 20, which can be moved easily and stably with the handle pipe 30 (gripping area) supported and the wheels 7 and 8 in contact with the ground or other moving surface.

In addition, as shown in the figures showing the installation state, the installation surface of the long hanging parts 1-3 and 1-4 and the installation surface of the wheels 7 and 8 are installed on the same installation surface, so that the blower 20 can be installed or moved horizontally.

In addition, the structure of the present invention allows the blower 20 to be stored in a single storage case in a disassembled form, making it possible to store all parts quickly and at low cost, which contributes to cost reduction.

The present invention has been described with reference to a preferred and easily understandable embodiment. However, various configurations, forms, and modifications of the embodiment are possible without departing from the broad spirit and scope of the embodiment. The above embodiment has been described with reference to one embodiment. Therefore, the scope of the present invention is not limited thereto.
