Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a saw that can collect chips generated by upward or sideways cutting work of interiors and exteriors of residential buildings without scattering.

[0002]

[Prior art]

 At the time of interior and exterior of a house building, etc., the chips generated when performing upward or sideways work with a saw may be broken even if the operator narrows his eyes or his body position is disturbed. It was designed so that it would not come into contact with it, or by wearing glasses such as for underwater use, to deal with the scattered chips.

[0003]

[Problems to be solved by the device]

 However, even if the worker responds in various ways like this, it is still not perfect, and it enters the eyes and ears of the operator, or the nose and mouth, and it is difficult to perform work for health management. I was going. For this reason, there is a lot of loss, and if it is forcibly continued, processing errors may occur, and if the chips from the upward or sideways cutting operation are scraped off as scraps, the designer and other workers may lose it. (For example, carpenters) disliked it, but various troubles remained even after the work was performed, and I felt very inconvenient in cutting work and health management.

[0004]

[Means for Solving the Problems]

 The present invention eliminates such inconvenience, and even if the work direction is upward, like the downward cutting work, it does not worry about the scattering of cutting chips, it is quick and does not pollute the work site with cutting chips. It is to provide a saw that can be done accurately. In other words, a saw body is detachably attached to a mounting rod with a handle at one end, and a storage unit consisting of a tubular body with an arbitrary cross section is inserted into the mounting rod and detachably installed on the handle, and an arbitrary shape is obtained. Insert the guide body into the storage body by covering the saw blade and the mounting rod with the guide body consisting of a guide body with an open end and a tubular guide body with an arbitrary cross section, and insert the guide body into the storage body. An elastic body is provided so that it can move up and down, and a guide plate is provided along the length, and guide pieces corresponding to the guide plate are provided inside the storage body or on the outer periphery of the guide body at an appropriate number of appropriate positions. .

In operation, when the saw blade is applied to the cutting location with a handle to start cutting, the receiving body hits the cutting location and covers the cutting location, and the guide receiving body stops, but the elastic body is used. Push to push the saw body out of the receiver along with the container. Then, when the saw body returns to the receiving body, chips generated by cutting with the saw blade enter the receiving body and are accumulated in the receiving body through the guide plate. At this time, the lateral deflection of the guide body or the storage body is prevented by the guide plate and the guide piece, and the vertical movement can be smoothly and correctly repeated. When the cutting ends, the contact of the receiving body disappears and the elastic body returns to the original state. After returning to the original state, remove the saw body by holding the handle from the container, remove the chips from the mounting hole, and install the saw body again in the container in the same way as described above and use it for the next cutting process.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. (Embodiment 1) Reference numeral 1 in the drawing is a saw body composed of a saw blade 2, a mounting rod 3 and a handle 4, and is suitable for an arbitrary cross section such as a circle, an ellipse or a square (the case of an ellipse is shown in the figure). A saw blade 2 is detachably fixed to one end of a mounting rod 3 having a length by a fastener or the like, and a handle 4 is provided at the other end to be integrated. Reference numeral 5 is a hermetically-sealed storage body made of a tubular body having an arbitrary cross section (the figure shows an elliptical case), and has insertion holes 5a and mounting holes 5b of arbitrary shapes on both end faces, and a fan-shaped or inner shape at the inner center. Or, a plurality of annular supporting plates 5C are projected inward, and a plurality of guide plates 5d are projecting at appropriate positions inside the housing 5 between the supporting plates 5C and the insertion holes 5a. A hole 5e is formed at a proper position on the outer periphery of the side, the mounting hole 5b is covered with the handle 4 as the handle 4 side, and the saw blade 2 is detachably installed so that the saw blade 2 protrudes from the insertion hole 5a. There is.

Reference numeral 6 denotes a guide receiving plate provided with an egg-shaped receiving body 7 having an open end at an arbitrary cross section (the figure shows an elliptical case) at one end of a guide body 8 made of a cylinder. A supporting plate 8a having an appropriate shape such as a fan shape or an annular shape is provided at an appropriate position on the outer circumference of the guide body 8, and a projecting piece 8b which can be fitted into the guide plate 5d is provided so as to project on the outer circumference of the guide body 8 corresponding to the guide plate 5d. The guide body 8 is inserted into the insertion hole 5a so that the saw blade 2 projects from the receiving body 7 and the elastic body 9 of the coil spring is provided between the supporting plates 5c and 8a to swing the guide receiving body 6 freely. I am trying. Numeral 10 is a buffer material having elasticity such as a ring, which is provided inside the housing 5 around the outer periphery of the insertion hole 5a so as to soften the impact of the support plate 8a. Reference numeral 11 denotes a lid, which is detachably provided in the hole 5e. The guide plate 5d and the guide piece 8b may be attached by providing the guide piece 8b in the housing body 5 and the guide plate 5d in the guide body 8.

In use, as shown in FIG. 7, while holding the handle 4 with the saw blade 2 facing the cutting portion of the ceiling and moving upward, the handle 4 is moved up and down to cut with the saw body 1. Go. At this time, when the handle 4 is pushed up, the receiving body 7 hits the ceiling plate 12 to cover the cut portion in a sealed state from below, and when the handle 4 is further pushed up, the elastic force of the elastic body 9 is overcome and the guide receiving plate 6 remains stationary. The storage body 5 and the saw body 1, which are integrated, rise. Then, when the handle 4 is raised to the proper position and the handle 4 is lowered, the ceiling 12 is cut by the saw blade 2, and the chips enter the receiving body 7 and collect in the storage body 5 from the guide body 8.

The cutting operation is repeated by repeating this operation, but the cutting chips are always received by the receiving body 7 and collected in the storage body 5 through the guide body 8 and are not scattered to the worker. . When cutting is completed, the saw body 1 is removed from the ceiling, the receiving body 7 hitting the ceiling plate 10 becomes free, is pushed by the elastic body 9 and returns to the state before use, and the cutting chips accumulated in the storage body 5 are put on the handle 4. Hold and pull the saw body 1 out of the storage body 5 and pull out from the mounting hole 5b, and re-install the saw body 1 in the storage body 5, or remove the lid body 11 and remove it from the hole 5e, and then dispose the lid body 11 again. After fitting, the following cutting process is performed. The horizontal deflection of the storage body 5 or the guide body 8 when it moves up and down is prevented by the guide piece 8b that fits and slides on the guide plate 5d.

Second Embodiment Since this embodiment is almost the same as the first embodiment and only the mounting state of the elastic body 9 is different, only different parts will be described. In the drawing, 13 is an elastic body of a coil spring, and a guide receiving plate 6 is swingably provided between the supporting plates 5c and 8a while being wound around the guiding member 8. Since it is the same as that of the first embodiment in use, the description thereof is omitted. In addition, in the embodiment, the case of the upward cutting of the ceiling is shown, but it can also be used for the lateral cutting of the side wall and the like. Further, the saw blade 2 may not be cut or may be used by replacing it with a cartridge suitable for the cutting position.

[0011]
