Description

Technical Field

[0001] The present invention relates to a panel body cutting auxiliary jig used when cutting and reducing a panel body constituting a fence according to the site.

Background Art

[0002] Conventionally, a panel body with a horizontal member such as a louver material attached to a fence has been used to blind the view so that the inside cannot be seen from the outside and to ensure ventilation. And various devices have been made when installing a fence at the boundary of adjacent lands. For example, when installing a fence, a panel body with a unit length (for example, 2 m) is pre-made at a factory to improve construction efficiency.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, the sites owned by customers are various. The length of one side where the fence is constructed also varies according to the customer's request, and it is necessary to cut and reduce the panel body constituting the fence to the required length. A panel body provided with a horizontal member such as a louver material does not necessarily have a shape suitable for the cutting and reducing work. When cutting the panel body, it is necessary to cut it in consideration of the fact that horizontal members such as louver materials bend, which requires careful work from the operator and deteriorates work efficiency. An object of the present invention is to provide a panel body cutting auxiliary jig that is convenient for an operator.

Embodiments for Carrying Out the Invention

[0007] The present invention relates to a panel body cutting auxiliary jig 6 particularly suitable for a panel body 1 having horizontal grids. As an embodiment included in the examples, the louver body (panel body) 1 having the louver material 11 as a horizontal grid will be described as an example, but the horizontal grid is not limited to the louver material 11. Hereinafter, the description will be made with reference to the drawings. However, the following drawings are created for the purpose of explanation, and in some cases, members unnecessary for the explanation may not be intentionally illustrated. Also, in some cases, members may be intentionally illustrated larger or smaller for the purpose of explanation, and the drawings do not show the exact scale. In the following description, the same reference numerals in different figures indicate parts having the same function, and repeated descriptions in each figure will be omitted as appropriate.

Example

[0008] (Embodiment 1) The louver body (panel body) 1 to be cut will be described. FIG. 1(A) is a front view of the louver body (panel body) 1, FIG. 1(B) is a cross-sectional view taken along line a-a attached to FIG. 1(A), and FIG. 1(C) is a longitudinal sectional view taken along line b-b attached to FIG. 1(A). The louver body (panel body) 1 includes an upper rail 3 and a lower rail 4, and has a horizontally long louver material (horizontal grid) 11 between the upper rail 3 and the lower rail 4. There are mounting frames 19 at both left and right ends of the louver body (panel body) 1. The mounting frame 19 has a mounting portion (not shown) for mounting the louver material (horizontal grid) 11. Further, a middle rail 7 is attached between the upper rail 3 and the lower rail 4 on the back surface of the central portion of the louver body (panel body) 1. The louver material (horizontal grid) 11 is fixed to the mounting frame 19 and the middle rail 7 by screws 18 one by one at a predetermined interval. The interval between the louver materials (horizontal grids) 11 adjacent to each other is appropriately determined in consideration of ventilation and light shielding properties.

[0009] Fig. 2(A) is a side view of the louver material (horizontal grid) 11. A number of louver materials (horizontal grids) 11 are attached and have the same shape. Its structure has a substantially rectangular frame portion 13 at the center in the vertical direction. On the outer side of the upper surface of the frame portion 13, a vertical surface portion 17 extending upward is connected, and it continues to form an upper louver surface portion 14 provided with an inclined surface portion 16. Also, on the inner side of the lower surface of the frame portion 13, an inclined surface portion 16 extending downward is connected, and it continues to form a lower louver surface portion 15 provided with a vertical surface portion 17. The frame portion 13 contributes to the strength of the louver material (horizontal grid) 11. Further, the frame portion 13 is a portion to be fastened with screws 18 to the mounting frames 19 (see Fig. 1(B)) provided at both ends of the louver body (panel body) 1 and the cross rails 7 (see Fig. 1(A)).

[0010] In the embodiment, only the uppermost part of the louver material (horizontal grid) 11 employs an uppermost louver material 12 having a structure different from that of the other parts of the louver material (horizontal grid) 11. The uppermost louver material 12 is provided with a short vertical surface portion 17 on the outer lower surface of the frame portion 13, and the lower louver surface portion 15 is constituted only by the vertical surface portion 17. The upper louver surface portion 14 has, in addition to the vertical surface portion 17 provided above the outer side of the frame portion 13 and the subsequent inclined surface portion 16, a fin portion 121 attached to the tip of the inclined surface portion 16. The fin portion 121 can prevent rainwater and sunlight from entering inside.

[0011] The louver materials (horizontal grids) 11 in Fig. 2(A) are arranged in a number vertically and attached with a space therebetween so that a ventilation path (shown by an arrow) is formed between the upper end of the lower louver material (horizontal grid) 11.

[0012] The panel body cutting auxiliary jig 6 can be used for any panel body 1 having the horizontal grid 11. In the embodiment, as an example of the panel body 1 having the horizontal grid 11 to be cut, the louver body (panel body) 1 used for the aforementioned fence is cited to explain the structure and usage of the panel body cutting auxiliary jig 6.

[0013] The louver body (panel body) 1 used for the fence is assembled at the factory and transported to the construction site in units of the louver body (panel body) 1. The operator determines the length of the fence according to the shape of the site, etc., based on the customer's requirements. In order to construct so as to fit within the determined length, some of the louver bodies (panel bodies) 1 are cut and reduced. The operator determines the position C1 where the louver body (panel body) 1 is to be cut according to the determined length. In order to improve the efficiency of the cutting and reducing operation, the panel body cutting assist jig 6 of the embodiment is used.

[0014] Figure 3 is an explanatory diagram of the installation process of the panel body cutting assist jig 6, and the louver material (horizontal grid) 11 is not shown for the sake of explanation. And Fig. 3(A) is a plan view of the louver body (panel body) 1 to be cut. First, the louver body (panel body) 1 to be cut is prepared. As a preparation for cutting, the louver body (panel body) 1 is placed horizontally. It is preferable to use a hand-held circular saw (cutting tool) 8 as the cutting tool.

[0015] Fig. 3(B) is a plan view of the state where the upper and lower crosspiece pedestals 5 and the support body 62 are installed. The state of Fig. 3(B) is the preparation state for cutting. Then the louver body (panel body) 1 is cut into two at the cutting position C1 and completely separated including the upper and lower crosspieces (3, 4). One of the cut louver bodies (panel bodies) 1 becomes the cut and reduced louver body (panel body) 1B and is used for the fence. The other of the cut louver bodies (panel bodies) 1 becomes the unused louver body (panel body) 1A.

[0016] The upper and lower crosspiece pedestals 5 are in contact with the lower surfaces of the upper and lower crosspieces (3, 4), and they separate the louver body (panel body) 1 from the ground surface by a predetermined distance so that the saw blade 82 (see FIG. 7) of the circular saw (cutting tool) 8 can pass through. In the embodiment, the upper and lower crosspiece pedestals 5 are made of square bars, but any type can be used as long as the louver body (panel body) 1 can be stably lifted from the ground surface. Also, since the upper and lower crosspiece pedestals 5 are used for the purpose of stably lifting from the ground surface, one upper and lower crosspiece pedestal 5 is placed on the side of the unused louver body (panel body) 1A with the cutting position C1 in between, and one upper and lower crosspiece pedestal 5 is placed on the side of the louver body (panel body) 1B that has been cut and reduced. If necessary, a greater number of upper and lower crosspiece pedestals 5 can be used.

[0017] As will be described later, the panel body cutting auxiliary jig 6 is roughly composed of two members, a support body 62 and a guide body 61. Before and after installing the upper and lower crosspiece pedestals 5 to support the upper crosspiece 3 and the lower crosspiece 4, one of the panel body cutting auxiliary jigs 6, the support body 62, is arranged close to the cutting position C1.

[0018] [Support body] FIG. 4 is a perspective view of the support body 62. The support body 62 supports the louver material (horizontal grid) 11 from below, has a base portion 623, and is provided with a horizontal grid lower surface support portion 622 that is attached on the base portion 623. The base portion 623 and the horizontal grid lower surface support portion 622 are fastened and fixed with screws (not shown) so that the horizontal grid lower surface support portion 622 does not move. The support body 62 is attached with the louver body (panel body) 1 lying down.

[0019] Then, the support 62 is installed such that the lower horizontal grid support portion 622 abuts against a plurality of louver members (horizontal grids) 11 of the louver body (panel body) 1 to be cut. Since the louver member (horizontal grid) 11 is pressed from above by a circular saw (cutting tool) 8 during cutting and tends to bend during the cutting operation, the lower horizontal grid support portion 622 supports the louver member (horizontal grid) 11 that tends to bend from below during the cutting operation. Since the attachment position of the support 62 has the function of supporting the louver member (horizontal grid) 11 that tends to bend during the cutting operation, it is preferably as close as possible to the position C1 to be cut. Further, in order to prevent damage when the louver member (horizontal grid) 11 abuts against the lower horizontal grid support portion 622, the surface of the lower horizontal grid support portion 622 may be covered with a cushioning member.

[0020] The support 62 has a rail positioning portion 621. The location where there is no lower horizontal grid support portion 622 provided in a plurality of divided parts serves as the rail positioning portion 621. The rail positioning portion 621 abuts against or fits into the upper rail 3 and the lower rail 4 of the louver body (panel body) 1 to be cut, so that the louver body (panel body) 1 does not shift during the cutting operation.

[0021] FIG. 5 is an explanatory diagram of the relationship between the rail positioning portion 621 of the support 62 and the louver body (panel body) 1 of various heights (height dimensions). The support 62 has a number of rail positioning portions 621. The number of rail positioning portions 621 enables the attachment of louver bodies (panel bodies) 1 of various heights (height dimensions). For the louver body (panel body) 1 used for a fence, it is common to prepare louver bodies (panel bodies) 1 with different height dimensions so as to meet the customer's requirements. In many cases, the height dimension often increases in units of 100 mm such as 600 mm, 700 mm, 800 mm, etc. The support 62 of the embodiment is provided with a number of rail positioning portions 621 so as to be able to accommodate louver bodies (panel bodies) 1 of various height dimensions. The upper rail 3 and the lower rail 4 of the louver body (panel body) 1 to be cut down and reduced are selected from among the number of rail positioning portions 621 and fitted into the rail positioning portion 621 that matches the height dimension.

[0022] The louver body (panel body) 1 is lying down during the cutting operation. For the sake of explanation, the side where the upper rail 3 in Fig. 5 is placed is defined as "up", and the side where the lower rail 4 is placed is defined as "down". As shown in Fig. 5, there are louver bodies (panel bodies 1) of various heights. However, regardless of the height dimension of the louver body (panel body) 1, the upper rail 4 is placed at the rail positioning portion 621 at the topmost "up" position. Depending on the height dimension of the louver body 1 (panel body) 1, the upper rail 3 may contact the end face of the rail positioning portion 621 or may simply be placed away from the rail positioning portion 621. On the other hand, the lower rail 4 is placed at different rail positioning portions 621 according to the height dimension of the louver body (panel body) 1. When the lower rail 4 is placed at the rail positioning portion 621 in the middle part, the lower rail 4 is just fitted into the rail positioning portion 621. By fitting the lower rail 4 into the rail positioning portion 621, even if the upper rail 3 is simply placed away from the rail positioning portion 621, the louver body (panel body) 1 cannot move either "up" or "down".

[0023] Among the louver bodies (panel bodies) 1 with the longest height dimension in Fig. 5, that is, the one shown at the bottom among the louver bodies (panel bodies) 1 of various heights, the lower rail 4 is in contact with the end face of the rail positioning portion 621, and the upper rail 3 is not in contact with the end of the rail positioning portion 621 and is simply placed on the support 62. At first glance, the louver body (panel body) 1 seems easy to move. In this case, by cutting the louver body (panel body) 1 with the circular saw (cutting tool) 8 from the lower rail 4 towards the upper rail 3, along with the movement of the circular saw (cutting tool) 8, the end of the rail positioning portion 621 is pushed in the direction of contacting the lower rail 4, and the louver body (panel body) 1 does not move during the cutting operation.

[0024] Depending on the type of the louver body (panel body) 1, there are also products that increase in 50 - mm units. In such a case, like the louver body (panel body) 1 shown as "louver body (panel body) 1 with a fractional height" in the figure, only the lower rail 4 is placed in contact with the rail positioning portion 621, and the upper rail 3 is freely placed without contacting the rail positioning portion 621 at the outermost end of the support body 62. As described above, by setting the cutting direction of the circular saw (cutting tool) 8 from the lower rail 4 to the upper rail 3, the louver body (panel body) 1 does not move "up" or "down" during the cutting operation. With this device, the support body 62 of the embodiment can cope with a louver body (panel body) 1 whose interval of the rail positioning portion 621 does not match.

[0025] [Guide body] FIG. 6 is a perspective view of the guide body 61. The guide body 61 has a guide 611 that presses the base 81 of the circular saw (cutting tool) 8 against the guide surface 6111 for cutting. Further, the guide body 61 includes a C - type fixture 612 and a butterfly bolt 624 for fixing the guide 611 across the upper and lower rails (3, 4). The guide 611 is an extruded shape and is a member having sufficient shape - retaining property without bending when guiding the circular saw (cutting tool) 8. FIG. 7 is a perspective view of the circular saw (cutting tool) 8. The operator makes the guide surface 6111 of the guide 611 contact the base 81 of the circular saw (cutting tool) 8 and cuts the louver body (panel body) 1 along the guide 611. The end face of the base 81 and the saw blade 82 are slightly separated, and the operator determines the position of the guide 611 considering the separated width.

[0026] FIG. 8 is an explanatory view of the installation process of the panel - body cutting auxiliary jig 6. FIG. 8(A) is a plan view of the louver body (panel body) 1 with the panel - body cutting auxiliary jig 6 attached. The louver material (horizontal grid) 11 is not shown for the sake of explanation. FIG. 8(B) is an intermediate step of attaching the panel - body cutting auxiliary jig 6. As shown in FIG. 8(A), in addition to the support body 62, the guide body 61 is attached to the louver body (panel body) 1 to complete the preparation for cutting by the circular saw (cutting tool) 8.

[0027] Figure 8(B) is a cross-sectional view taken along line A-A attached to Figure 8(A), and Figure 8(C) is a cross-sectional view taken along line B-B attached to Figure 8(A). Since the C-shaped fixtures 612 of the upper rail 3 and the lower rail 4 are the same members, the attachment to the upper rail 3 will be described as an example.

[0028] Since the guide surface 6111 guides the base 81 of the circular saw (cutting tool) 8, the operator places the guide 611 across between the upper and lower rails (3, 4) so that it can be cut at the cutting position C1 considering the positions of the base 81 and the saw blade 82. The passed guide 611 is fitted into the C-shaped fixture 612 together with the lower rail 4 and fixed by the wing bolt 624.

[0029] The panel body cutting auxiliary jig 6 is a member composed of a guide body 61 and a support body 62. The attachment procedure of the support body 62 and the guide body 61 to the louver body (panel body) 1 can be either first, and it is not necessary to be in the order of the embodiment. The support body 62 is arranged at a position separated from the guide body 61 considering the size of the circular saw (cutting tool) 8.

[0030] The place where the cutting operation is performed is preferably a stable place with a horizontal working surface. Even if there is a slight inclination, there is no hindrance to the cutting operation. When the inclination causes an obstacle, it is a preferred mode to correct it to be horizontal with a separately prepared spacer (not shown).

[0031] Since the C-shaped fixture 612 that fixes the guide body 61 to the louver body (panel body) 1 can be appropriately moved, even if the height dimension of the louver body (panel body) 1 changes, it can be dealt with by sliding it with respect to the guide 611.

[0032] (Effect of the embodiment) As described above, when the panel body cutting auxiliary jig 6 cuts and contracts the louver body (panel body) 1, the action of the rail positioning portion 621 of the support body 62 prevents the lateral movement of the louver body (panel body) 1. Further, due to the action of the horizontal grid lower surface support portion 622 of the support body 62, even if the heavy circular saw (cutting tool) 8 is placed on the louver material (horizontal grid) 11, the louver material (horizontal grid) 11 is prevented from bending downward. Preventing bending improves work efficiency and also prevents the louver material (horizontal grid) 11 from bending and being cut as a result of bending. The guide body 61 guides the circular saw (cutting tool) 8 and enables the operator to cut the stable louver body (panel body) 1 at the cutting position C1 determined by the operator by the action of the support body 62. By using the panel body cutting auxiliary jig 6, the louver body (panel body) 1 can be cut with a clean cross-section. Although the unused louver body (panel body) 1A is generated along with the production of the cut and contracted louver body (panel body) 1B, since the cut surface is clean, the unused louver body (panel body) 1A can also be used as the cut and contracted louver body (panel body) 1B at other sites.

[0033] As described above, the embodiments according to the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and design changes and the like within the scope not departing from the gist of the present invention are also included in the present invention.
