Abstract

(57) [Abstract] [Purpose] To provide a field rim receiving and cutting tool that can easily cut the field rim receiving without protruding from the cutting end face of the ceiling finishing material. [Structure] Of a pair of cutting blades 4 and 5 provided on the upper ends of the handles 1 and 2, two cutting blades above and below one cutting blade 4 have a V-shaped cross section in the thickness direction of the cutting blade 4. The grooves 9 and 9 are provided. The interval between the recessed grooves 9, 9 is made to coincide with the interval between the upper and lower protruding portions of the field edge receiver 22.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a field rim receiving and cutting tool used for building ceiling construction and the like.

[0002]

[Prior art]

 A lightweight ceiling used for a building ceiling, for example, uses a hanging bolt 21 to suspend a field edge receiver 22 having a U-shaped cross section from a frame 23 as shown in FIG. 5, and a field edge 24 attached to the lower surface thereof. The structure supports the ceiling finishing material 25. Therefore, when a lighting fixture, an air conditioning outlet, etc. are provided in the ceiling, it is necessary to make a hole in the ceiling finishing material 25 and cut the field rim receiver 22 as shown in FIG.

Conventionally, hand saws and electric cutters have been used as field edge cutting tools for this purpose. However, hand saws have the drawback of being unstable, time consuming and poor in workability, and electric cutters have the drawbacks of discoloring the finishing material and the risk of fire because sparks and dust are scattered around. It was Therefore, it is conceivable to cut the field edge receiver 22 using a general cutting tool that has a pair of cutting blades at the upper end of the handle.In that case, the field edge receiver 22 is cut rather than the cut edge surface of the ceiling finishing material 25. The cutting end face of 22 protrudes inside the hole by the thickness of the cutting blade. For this reason, there is a problem in that the protruding portion becomes an obstacle when mounting a lighting fixture or the like, and the mounting cannot be performed.

[0004]

[Problems to be solved by the device]

 The present invention has been made to solve the above-mentioned conventional problems, and to provide a field edge cutting tool that can easily cut the field edge without protruding from the cutting edge of the ceiling finishing material. It is a thing.

[0005]

[Means for Solving the Problems]

 The present invention made in order to solve the above-mentioned problems has a V-shape extending in the thickness direction of the cutting blade at two positions above and below one of the pair of cutting blades provided at the upper end of the handle. It is characterized in that a groove having a cross section is provided.

[0006]

[Action]

 The field edge receiving and cutting tool of the present invention is provided with a groove having a V-shaped cross section extending in the thickness direction of the cutting blade at two positions above and below one cutting blade. It is possible to insert the upper and lower protrusions of the box-shaped field rim receiver, and incline the field rim cutting tool so that the cutting edge is deeper than the cutting end face of the ceiling finishing material for cutting. Therefore, it is possible to cut the field rim receiver without protruding it from the cut end surface of the ceiling finishing material. When cutting the field edge receiver on the opposite side of the hole, the entire field edge receiving and cutting tool can be inclined to the opposite side for cutting.

[0007]

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. 1 and 2 show a field edge cutting tool of an embodiment, 1 and 2 are a pair of handles that can be opened and closed around a pin 3, and 4 and 5 are a pair of cutting that can be opened and closed around a pin 6. It is a blade. Since the lower ends of these cutting blades 4 and 5 are connected to the upper and outer ends of the handles 1 and 2 by the pins 7 and 8, when the handles 1 and 2 are opened as shown in FIG. The cutting blades 4 and 5 are also closed when the handles 1 and 2 are closed as shown in FIG.

As shown in an enlarged manner in FIG. 3, concave grooves 9, 9 are provided at upper and lower portions of one cutting blade 4. These concave grooves 9 and 9 are for inserting the upper and lower protrusions of the field rim receiver 22 having a U-shaped cross section, and therefore the distance between these groove grooves 9 and 9 is larger than that of the field rim receiver 22. It should be set equal to the interval of the protrusions.

Further, these recessed grooves 9, 9 are assumed to have a cross section that expands in a V-shape in the thickness direction of the cutting blade 4 from the surface in contact with another cutting blade 5 toward the surface on the opposite side. . The opening angle is about 60 ° in the embodiment.

As shown in FIG. 4, the field rim receiving and cutting tool of the present invention having the above-described structure inserts the cutting blades 4 and 5 through the holes in the ceiling finishing material ceiling finishing material 25 into the field edge receiving member 22. It is used for cutting. At this time, the upper and lower protruding portions of the field edge receiver 22 are inserted into the recessed grooves 9 and 9 provided at the upper and lower portions of the one cutting blade 4 for cutting. Has a V-shaped cross section in the thickness direction of the cutting blade 4, the cutting blades 4 and 5 are inclined so that the cutting edge is deeper than the cutting end surface of the ceiling finishing material 25 as shown in FIG. Can be cut. Further, when cutting the field receiver 22 on the opposite side of the hole, the cutting blades 4 and 5 can be inclined to the opposite side and cut. Therefore, on both sides of the hole formed in the ceiling finishing material 25, the field edge receiver 22 can be cut deeper than the cut end surface of the ceiling finishing material 25, and the field edge receiving element 22 can be attached when mounting a lighting fixture or the like. Does not get in the way.

[0011]

[Effect of device]

 As described above, the field edge receiving / cutting tool of the present invention is provided with the concave groove having a V-shaped cross section in the thickness direction of the cutting blade at two positions above and below one cutting blade. There is an advantage that the rim receiver can be easily cut without protruding from the cut end surface of the ceiling finishing material.
