Description

  The present invention relates to a tool used to cut a part of a ridge formed on a sash frame of an aluminum sash when joining aluminum sashes in a horizontal direction or a vertical direction.

When joining the aluminum sash provided with the following configurations (1) to (4) in the horizontal direction or the vertical direction, it is necessary to cut out the following contact portion for attaching the second ridge.
(1) On the outer surface of the sash frame,
(2) A first ridge and a second ridge that extend along the length direction of the sash frame and project in a direction substantially orthogonal to the outer surface of the sash frame are spaced apart in the width direction of the sash frame. As well as
(3) Projected from the tip of the first ridge toward the second heel side at the tip of the first ridge, from the inside of the window opening to the end face of the structural material constituting the window opening It has an abutting part that is abutted,
(4) The second ridge is projected from the intermediate portion of the second ridge toward the first ridge, and projects from the inside of the window opening portion to the end surface of the structural material constituting the window opening portion. An abutting portion to be applied, and further, a portion between the formation position of the abutting portion of the second fence and the tip of the second fence is attached to a surface of the structural material facing the outside of the building Aluminum sash used as a contact part.

  Conventionally, this excision operation is performed by cutting the incision line with a cutter along the connecting portion between the attachment contact portion and the abutting portion in the second ridge and then using the pliers or the like to cut the attachment contact portion. It took time and labor to bend up and down around the center of bending. In addition, since the force cannot be applied uniformly at the time of bending unless the depth of the cut line by the cutter is uniform, there are not a few cases where the attachment contact portion cannot be folded cleanly. In addition, special care must be taken so as not to cause scratches or distortions in the remaining portions of the second ridges during the folding. After the mounting contact part is broken off, the abutment part of the second hook is fitted into a part of the connecting material such as a connecting vertical member or seamless material, and the two aluminum sashes are joined together. If the scratches or distortions occur at the time of folding, it becomes difficult to perform joining by this vertical material. If such scratches or distortions are generated, an unnecessary gap or the like is further generated at the joining portion, and waterproofing is not preferable.

  The main problem to be solved by the present invention is that a part of the ridge formed on the sash frame of the aluminum sash required for joining the aluminum sash in the horizontal direction or the vertical direction can be easily and appropriately removed. It is in the point to make it.

In order to solve the above problems, in the present invention, an aluminum sash cutting tool is provided with the following configurations (1) to (4).
(1) On the outer surface of the sash frame,
A first ridge and a second ridge that extend along the length direction of the sash frame and project in a direction substantially orthogonal to the outer surface of the sash frame are spaced apart in the width direction of the sash frame. With
It is protruded from the tip of the first ridge toward the second ridge side at the tip of the first ridge, and is abutted from the inside of the window opening on the end face of the structural material constituting the window opening. With an abutment,

A contact portion for attaching to the surface of the structural material facing the outside of the building from the position where the abutment portion of the second heel is formed to the tip of the second heel Aluminum sash
A tool for cutting the contact portion for attaching the second scissors into a coiled shape when joining in the lateral direction or the longitudinal direction,
(2) a bearing body having an outer surface portion as a gripping surface portion;
(3) With the front end protruding from the front end of the bearing body, the bearing body is rotatably inserted into the bearing body, and has a winding rotary body with the rear end as a connection to the driving means. And
(4) At least one split groove for dividing the front end of the winding rotary body into the left and right is formed at the front end of the winding rotary body, and the contact portion for attaching the second rod is formed in the split groove. In this state, the take-up rotating body is rotationally driven while gripping the bearing body, so that the attachment contact portion is cut off while being wound around the front end of the take-up rotary body.

  According to such a configuration, when connecting the two aluminum sashes, the contact portion for attaching the second ridge is not previously attached to the aluminum sash with a cutter or the like, and time is not required. In addition, it can be easily and appropriately excised without causing scratches or distortion in the remaining portion of the aluminum sash. That is, according to such a cutting tool, after inserting the contact portion for attaching the second ridge into the split groove of the winding rotary body, more specifically, it is positioned on the one corner side of the aluminum sash. The base part of the attachment contact portion is driven by rotating the take-up rotating body after inserting the contact portion for attachment of the second rod (the winding start start end of the attachment contact portion) into the split groove. That is, the connecting portion can be continuously broken by concentrating the shearing force on the connecting portion between the attachment contact portion and the abutting portion of the second rod. The attachment contact portion that is cut off by this continuous breakage is gradually wound around the outer periphery of the winding rotary member to form a coil. At the stage where the breakage reaches the end (winding end) of the second hook mounted on the other corner of the aluminum sash by the rotational drive of the winding rotary body, the mounting contact Will be completely excised. After the resection is completed, the take-up rotating body is extracted from the attachment contact portion that has been wound up into a coil shape, and is prepared for the next operation. Since the excised contact portions for attachment are collected in a coil shape, subsequent disposal processing and the like are facilitated.

  A male screw part is formed on the outer peripheral part of the front end of the winding rotary body, and a nut body provided with an internal thread part engaging with the male screw part on the front end is screwed to the front end. In some cases, the attachment contact portion is inserted into the split groove such that the tip of the attachment contact portion abuts against the end face directed to the front end of the rotary assembly.

  In this case, the mounting contact is made by abutting the end face of the nut body against the tip of the mounting contact part inserted in the split groove by screwing the nut body back and forth according to the width of the mounting contact part. The mounting contact portion can be wound in a state where the base portion of the mounting portion is accommodated in the split groove, and the mounting contact portion can be cut off with good finish along the length direction of the sash frame. Moreover, the deformation | transformation which expands the pitch between the split grooves formed in the winding rotary body with this nut body can be suppressed.

The two aluminum sashes 100 and 100 are connected by the connecting member 300 by being interposed between the sashes 100 and 100. More specifically, in the groove formed by the rail-like body 304 formed so as to direct the groove opening to the outside of the window opening portions formed on both surfaces of the substrate portion 301 constituting the connecting member 300, The two aluminum sashes 100 and 100 are joined together by the connecting member 300 so that the abutting portion 104a of the second collar 104 is inserted. (Fig. 6)

  The cutting tool according to this embodiment can easily and appropriately cut the attachment contact portion 104c of the second ridge 104 when the two aluminum sashes 100, 100 are joined together. That is, according to such a cutting tool, more specifically, after the contact portion 104c for attaching the second flange 104 is inserted into the split groove 25 of the winding rotary body 2 described later, more specifically, the aluminum sash 100 On the other hand, after the attachment contact portion 104c of the second flange 104 located on the corner side is inserted into the split groove 25, the winding rotary body 2 is driven to rotate, whereby the attachment contact portion 104c of the attachment portion 104c is rotated. The connecting portion 104d can be continuously broken by concentrating the shearing force on the connecting portion 104d between the mounting contact portion 104c and the abutting portion 104a of the second flange 104. The attachment contact portion 104c separated by the continuous breakage is gradually wound around the outer peripheral portion of the winding rotary body 2 to be coiled. At the stage where the breakage reaches the end of the contact portion 104c for attachment of the second flange 104 located on the other corner side of the aluminum sash 100 by the rotational drive of the winding rotary body 2, the attachment contact portion 104c is It will be completely excised. After the excision is completed, the take-up rotating body 2 is extracted from the attachment contact portion 104c that has been wound up into a coil shape, and is prepared for the next operation. Since the removed attachment contact portion 104c is collected in a coil shape, subsequent disposal processing and the like are facilitated.

  Such excision is performed by operating the winding rotary body 2 side in a state where the mounting contact portion 104c of the second rod 104 is inserted into the split groove 25 of the winding rotary body 2. It is preferable that the connecting portion 104d between the portion 104c and the abutting portion 104a is cracked or folded. (FIG. 7) By making the cut as described above, the attachment contact portion 104c of the second ridge 104 can be cut more easily and appropriately. That is, the attachment contact portion 104c can be cut so that the fracture surface 104e of the attachment contact portion 104c is located on the same surface as the outer surface 104b of the abutting portion 104a of the second flange 104. In this excision, unnecessary deformation can be prevented from occurring on the abutting portion 104a side of the remaining second ridge 104. Since the attachment contact portion 104c can be appropriately excised in this manner, the abutting portion 104a of the second ridge 104 remaining in the groove of the connecting member 300 can be inserted without any trouble.

  Such a cutting tool has a bearing body 1 and the winding rotary body 2.

  The bearing body portion 1 has an outer surface portion as a gripping surface portion 10. In the illustrated example, the bearing body 1 is configured to have a cylindrical shape in which both the cylinder front end and the cylinder rear end are released, and the winding rotary body 2 is moved from the front end to the rear end 21 side. The winding rotary body 2 is received inside and is rotatably supported. In the illustrated example, one end 30 side of the crank rod body 3 is rotatably inserted into the bearing body 1 from the rear end of the bearing body 1. One end 30 of the crank rod body 3 and the rear end 21 of the winding rotary body 2 are connected. In the illustrated example, the operator grips the grip 32 provided on the other end portion 31 of the crank rod body 3 with the other hand while holding the bearing barrel portion 1 with one hand. By operating the crank rod body 3 so as to rotate the one end portion 30 side of the bearing body 1 as a bearing, the winding rotary body 2 is driven to rotate in a state where the bearing body 1 is a bearing. ing. That is, in the example shown in the figure, the crank rod body 3 functions as drive means described later. Separately from the example shown in the figure, if a rotating part such as a tool that is driven to rotate by a motor such as an impact driver or an electric screwdriver is connected to the rear end 21 part of the winding rotary body 2, the winding rotation is performed by the motor. The body 2 can also be driven to rotate. In addition, the cutting tool can be configured to include a motor unit for rotationally driving the winding rotary body 2.

The narrow-diameter portion 24 is configured to have a polygonal cross-sectional shape, and is released at the end of the one end portion 30 of the crank rod body 3 and follows this polygonal shape extending along the length direction of the one end portion 30. By fitting the small-diameter portion 24 into the fitting hole 33 having an inner shape, the end portion 30 of the crank rod body 3 is integrated.

  Further, at the front end 20 of the winding rotator 2, at least one split groove 25 that divides the front end 20 of the winding rotator 2 into the left and right is formed. With the attachment contact portion 104c of 104 attached, the take-up rotating body 2 is driven to rotate while gripping the bearing body 1 so that the attachment contact portion 104c is moved to the front end 20 of the take-up rotary body 2. It can be excised as described above while being wound around.

  In the illustrated example, it is released outward at the end of the large-diameter portion 23 of the winding rotary body 2, has a depth reaching the base side of the large-diameter portion 23, and The large-diameter portion 23 is divided into right and left by a split groove 25 released outward on both sides.

  Further, in the illustrated example, chamfered portions 26 are formed at both corners of the groove wall 25a of the dividing groove 25 and located at the end of the large-diameter portion 23. The attachment contact portion 104 c is easily inserted into the split groove 25. Further, the groove wall 25a of the split groove 25 located at the end of the large-diameter portion 23 is flat between the chamfered portions 26, and the groove width of the split groove 25 is equal to the thickness of the attachment contact portion 104c. Since the dimensions are almost the same or slightly wider than this, it is easy to insert the attachment contact portion 104c into the split groove 25, but on the side of the cutting tool at the base of the inserted attachment contact portion 104c. This makes it easy to apply a force to the connecting portion 104d between the mounting contact portion 104c and the abutting portion at the time of excision. is there.

  If a chamfered portion is further provided at the outer peripheral portion of the large-diameter portion 23 and located at the end of the large-diameter portion 23, the cracking or folding operation is performed. The end of the outer peripheral portion of the large-diameter portion 23 can be made difficult to come into contact with the outer surface 104b of the abutting portion 104a of the second flange 104. It is possible to prevent unnecessary scratches on the outer surface.

  In this embodiment, a male screw portion 27 is formed on the outer peripheral portion of the front end 20 of the winding rotary body 2, and a female screw portion that meshes with the male screw portion 27 is formed on the inner peripheral portion at the front end. The nut body 28 provided is screwed, and the end of the attachment contact portion 104c is abutted against the end surface 28a of the nut body 28 facing the front end 20 of the winding rotary body 2 so that the split groove 25 has The attachment contact portion 104c is inserted.
