Description

  The present invention relates to an improvement in a method for processing a grooved frame material such as a sill or a duck that can be applied to various fittings such as sliding doors, doors, and hanging doors installed in a building.

  In general, the sill and the duck have been formed by recessing a groove in a solid wooden floor for a long time, but recently, a base member surface with a separate cover member for the groove has been widely used. .

  Patent Document 1 discloses a sill that covers a base member with a detachable cover member. According to this threshold, the base member is made of wood and the cover member is made of resin, so that it can be formed at low cost, and even if the surface is damaged, only the cover member is replaced. It can be restored to its original state, and the cost required for replacement is lower than the replacement of solid wood.

However, in the sill described in Patent Document 1, since the cover member is integrally formed over the entire width of the base member, an increase in the size of the mold is unavoidable in manufacturing, and the number of grooves depends on the number of grooves. However, even with the same number of grooves, the arrangement and width of the grooves differ depending on the form and thickness of the sliding door, and a large number of cover member variations must be prepared. Further, even when the cover member is partially damaged, it is necessary to replace the entire cover member, which is unreasonable.
In order to eliminate this drawback, it has been considered that the cover member is constituted by another member on both sides partitioned by the groove as in Patent Document 2, and the cover member is formed by a different member, but the molding error of the cover member, change with time, temperature Due to changes or the like, it was difficult to accurately match the edge of the cover member with the groove edge.
In order to eliminate the defect, it is conceivable to cut the groove after covering the cover member over the entire width of the base member as in Patent Document 3. In this case, the edge of the cover member can be made to coincide with the groove edge, but it is impossible to solve the disadvantage that the mold is enlarged in the case of a wide width and a large number of molds corresponding to the width are required.

  Accordingly, the present invention has been made to solve such a problem, and the edge of the groove portion 4 of the base member 1 and the edge portion of the cover member 2 corresponding thereto can be easily matched, The seam between the member 1 and the cover member 2 can be easily fitted, and the number of various grooves and groove positions can be changed with a small number of members. Even when there are a wide variety of variations like these, a small number of separation cover members 2a, 2b Of the frame material with a groove that can cope with variations with many groove positions, groove widths and door thicknesses, and can dramatically reduce the number of parts and dies. An object is to provide a processing method.

In the first invention, the cut margins 5a, 5b,... Are formed on the opposite edges of the separation cover members 2a and 2b so as to project from the planned groove portion 3, and the groove portion 4 of the base member 1 is finally formed. The separation cover members 2a, 2b,... Are mounted on both sides of the planned groove portion 3 to be applied so that the cut margins 5a, 5b,. The excess portions of the cut margins 5a, 5b of 2a, 2b... And the groove portion 4 are cut together.

In the second invention, the preliminary groove 31 having a slightly narrower width than the final groove 4 is provided in the planned groove 3 of the base member 1, and the separation cover members 2 a, 2 b. It is characterized in that it is mounted and then cut off together with the excess portions on both edges of the preliminary groove 31.

In the third aspect of the invention, the separation cover members 2a, 2b,... Are formed on both sides of the planned groove portion 3 where the groove portion 4 is finally provided, and the cut margins 5a, 5b,. The pre-groove portion 3 of the base member 1 is mounted so as to protrude from the pre-planned portion 3, and a preliminary groove 31 having a slightly narrower width than the final groove portion 4 is provided, and then the separation cover members 2a, 2b,. The excess portions of the margins 5a, 5b... And the excess portions of the preliminary grooves 31 are cut together.

The fourth invention is characterized in that the color of the separation cover members 2a, 2b,... Corresponds to the color tone of the floor, ceiling, etc. of the room to be constructed.

In the present invention , by separating the cover member 2 into the separation cover members 2a, 2b,..., The molding die is not enlarged as in the case of the integral separation cover, and thus the manufacturing cost is reduced. Can be made.
Further, when the molding accuracy of the separation cover member is high, the groove edge and the cut end surface of the cover member are aligned, and appearance deterioration can be prevented.
In addition, when the number of sills or duck grooves is increased to one groove, two grooves or more, or when the groove core is changed, separate separation cover members 2a, 2b,... And intermediate separation cover members are prepared. Any type can be supported.
When the rail member 4a is separately attached to the groove portion 4, if a horizontal flange portion is projected outward from the upper edge of the rail member 4a, the flange portion is a butt portion between the edge of the separation cover member and the groove portion. Therefore, there is no practical problem even if the dimensional accuracy of the separation cover member is low.

Further, the separation cover members 2a, 2b,... Are generally obtained by extrusion molding of synthetic resin, but due to the properties of the molding, in addition to dimensional errors, distortion and undulation due to changes with time and temperature changes. Is unavoidable. However, in the first invention , the separation cover members 2a, 2b,... Are provided on both sides of the planned groove portion 3 where the groove portion 4 is to be finally formed, and the cut margins 5a, 5b,. Since it is mounted so that it projects over the planned groove portion 3, and then the excess portions of the cut margins 5a, 5b... Of the separation cover members 2a, 2b. The separation cover members 2a, 2b,... And the groove 4 are precisely matched, and even when the rail member 4a of the groove 4 is fitted, the flange does not protrude horizontally on the upper edge of the rail member. Even if it is a thing, it is hard to produce a clearance gap between the cut end of a isolation | separation cover member, and can aim at the improvement of an external appearance.

In the first aspect of the present invention , if the cut margins 5a, 5b,... It can be set up to 5 mm. And when there are three types of groove position changes and separation base members are required at intervals of 1.5 mm, there is one type with the maximum 4.5 mm cut margin, and the conventional three types The required separation cover member can be reduced to one type. Further, even if the cut margin is 3 mm, two types can be reduced to one type.
Furthermore, even if the number of grooves is normal, even if the number of grooves is 1 to 4, the groove width and groove core change for each number of grooves. Therefore, conventionally, a corresponding number of separation cover members must be prepared. However, in the first aspect of the invention , it is possible to share an object whose dimensions are close within the range of the width of the cut margin. The number of types of cover members and the number of molds required for the molding can be reduced, leading to cost improvement in manufacturing.

In the second invention , the preliminary groove 31 having a slightly narrower width than the final groove portion 4 is provided in the planned groove portion 3 of the base member 1, and the separation cover members 2a, 2b,. .. is attached, and then the extra portions on both edges of the preliminary groove 31 are cut together, so even if the groove width is different, the final groove portion 4 is a blade that widens one side of the groove. Can be cut.
Conventionally, since it is common to use an expensive cutting device equipped with a so-called three-face finishing blade according to the groove width, it is necessary to prepare a blade according to the groove width. 31 can be cut one side at a time and widened to a predetermined groove width, the cost can be reduced, and since the preliminary groove 31 is provided in advance, cut waste generated during widening can be reduced, and cut waste Emission can be facilitated and the working environment can be improved.
That is, when grooving is performed on the flat base member 1 in FIG. 9, the three-way cutting cutter 101 is generally used as shown in (b). However, if the groove width is different, a blade with a corresponding blade width is prepared. In addition, since cut waste generated by grooving comes out all at once, it must be discharged, and a large suction device and a place for storing the cut waste are required. If the unnecessary portions of the cut margins 5a, 5b... Of the separating cover members 2a, 2b... And the spare groove 31 are cut, the grooves are cut by the two-way cutter 100 as shown in FIG. Since cutting can be performed, even if the groove width is changed, only one type of cutter can be used, and the generation of cut waste is reduced, the discharge operation and space are made compact, and the working environment is improved.

In the third invention , in addition to the second invention , since the cut margins 5a, 5b,... Are projected from the planned groove portion 3 of the base member 1, the groove portion 4 and the cut margins 5a, 5b,. The cut edges can be accurately aligned, and the effects of sharing the separation cover member and reducing the number of molds can be further enhanced.

In the fourth invention , by changing the color of the separation cover materials 2a, 2b..., The color of the sill matches the color of the room when the color of the wall or floor of the room to be constructed is different. Try to match things. That is, since the sill and the duck are usually manufactured independently of the walls and floors of the room, the duck and the sill may be uncomfortable, but such drawbacks can be solved.

  In addition, although the above showed the example which gives a groove | channel to the horizontal frame material of a sill and Kamoi, in the case of the sliding door of an up-and-down movement, processing a groove part on the right and left vertical frame material is also included.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an outline of the vicinity of an opening provided in a wall 14 that partitions adjacent rooms, hallways, etc., and the opening frame 10 is composed of a sill 20, vertical frames 30, 30 and a duck 40. This is mainly related to the processing of the frame member provided with the groove 4 for the sliding door 15 such as the sill 20 and the duck 40.

  In FIG. 1, a wall is partitioned in a building, and on both sides of each wall 14 constituting a room or a room and a hallway, an opening is provided for people to enter and leave between rooms (or between a room and a hallway). ing. The opening frame 10 constituting the opening is composed of a lower edge sill 20, a pair of vertical frames 30, 30 and an upper edge duck 40, to which one or more sliding doors 15 for opening and closing the opening are attached. Out. There may be a door pocket portion that is accommodated when the sliding door 15 is opened as necessary.

  A groove 4 corresponding to the number of sliding doors 15 is provided on the lower surface of the duck 40, and a groove 4 corresponding to the number of sliding doors 15 is also provided on the sill 20, which is the upper surface of the floor base material and constitutes the wall 14 For example, a long runner having a U-shaped cross-section, V-shape, or the like is installed with its opening side facing upward, and a plurality of outside ceiling field edges constituting the wall 14 are the same as the above runners. The runner is positioned so that its opening side is directed downward, orthogonal to the ceiling edge, and overlapped with the runner in plan view, and positioned on the same axis.

  The sill 20 is obtained by mounting a cover member 2 on the surface of a base member 1 formed in a long shape, and the cover member 2 is constituted by a plurality of separation cover members 2a, 2b... As shown in FIG. . A backing material is attached to the back surface of the base member 1 as necessary. These are fixed by partial or full adhesive application as required.

  The base member 1 is generally made of wood (wood) or low-foamed resin formed by processing a wood member such as laminated wood or plywood into a long shape, and at least the surface of one wall plate of the wall 14 To the surface of the other wall plate, and has a length from one side edge of the opening to the other side edge. Further, as shown in FIG. 3, finally, the surface of the base member 1 is, for example, one or two or more for accommodating the lower end portion of the sliding door 15 itself or the ridge portion 15a attached to the lower end thereof. The groove portion 4 is extended in the longitudinal direction, but until the groove portion 4 is cut, separation cover members 2a and 2b are mounted on both sides of the planned groove portion 3 as shown in FIG. .

If the separation cover members 2a and 2b are made of a resin having a certain thickness and have a sufficient strength, the base member 1 has a normal hardness and strength, as well as a high level such as a closed-cell foamed polystyrene. It can be made of a lightweight material such as foamed resin. In that case, nailing and screwing can be carried out directly without difficulty even if the base is not preliminarily provided with a screw hole for attaching to the structural housing or a hole for nailing.
Further, the separation cover members 2a, 2b,... May have their surfaces covered with a thin film such as a coating film, a resin film, or a sheet.

  Here, a taper piece 22h for eliminating a step with the floor surface 11 connected to the sill 20 is provided on the outside of the separation cover members 2a and 2b that does not correspond to the groove portion 4 as necessary. Reference numeral 7 denotes a hole drilled at appropriate positions on both ends of the base 1, which is used to form a frame by fixing a frame material to the structural housing.

  FIG. 11B shows an example in which there are two grooves 4. In this case, the separation cover member 2 c mounted between the grooves 4, 4 does not require the taper piece 22 h, and the groove 4 If the number increases, the separation cover member 2c without the taper piece 22h is increased accordingly.

  One or two or more protruding portions 22p are provided over the entire length of the lower surface side of the separation cover members 2a, 2b... As necessary, and the upper surface of the base member 1 corresponds to this. The recesses 21g are formed, and the separation cover members 2a, 2b,... Are partially or entirely bonded to the base member 1 in a state where both are engaged.

  In addition, instead of the taper piece 22h of the separation cover members 2a and 2b, it may be formed in an L-shaped cross section including a leg portion 22a that covers one of the facets of the base member 1 (imagination in FIG. 11B). See line). The ends of the separation cover members 2a and 2b of the Kamoi 40 are also opposite in direction to the upward direction, but the outside of the base member 1 is covered with the leg portions 22a.

  The wall of the room to be constructed by setting the color of the separation cover materials 2a, 2b,... Constituting the surface cover member 2 to the same color or similar color corresponding to the floor or wall of the room to be constructed. Even if the color variation of the floor, ceiling, etc. increases, the color of the sill and the duck is different from the color tone of the floor, the ceiling, etc., and the color of the sill and the duck matches the color of the room To be matched.

  In the present embodiment, the sill 20 is formed so that the thickness of the state in which the cover member 2 is bonded to the base member 1 is the same as or slightly larger than the finishing material of the floor 11.

  Further, in the present embodiment, the floor 11 is provided with a frame member accommodating portion (indicated by reference numeral 16 in FIG. 2) at a position facing the duck 40, and the sill 20 includes the frame member. It is attached in the state accommodated in the accommodating part 16. Since the sill 20 is formed to have substantially the same thickness as the finishing material of the floor 11, the frame member accommodating portion 16 does not lay the finishing material of the floor 11 at a position facing the duck 40. Easy to form. Moreover, the taper piece 22h formed in the separation cover members 2a and 2b overlaps with the edge of the surface of the finishing material of the floor 11 adjacent to the sill 20 in a state where the sill 20 is accommodated in the frame member accommodating portion 16. (See FIG. 2). As a result, in addition to eliminating the level difference, the seams between the finishes of the sill 20 and the floor 11 are blocked, and there is no possibility that dust and dust accumulate on the seams.

Moreover, you may make it provide the through-hole etc. for attaching the said threshold 20 to the frame member accommodating part 16 etc. in the threshold 20 as needed. For example, in the present embodiment, a plurality of counterbore (not shown) may be provided in the groove portion 4 of the sill 20, and convenience may be provided when the sill 20 is attached with nails or the like.
Similarly to this, it is also possible to provide through holes such as counterbore holes in the duck 40 and the vertical frame 30.
A rail 4a made of an arbitrary material such as aluminum or resin corresponding to the ridge 15a or runner, roller, or the like is attached to the groove portion 4 as necessary. Similarly to the case of the sill 20, the groove portion 4 of the duck 40 can be cut after the separation cover members 2a and 2b are mounted. Further, if the sliding door is vertically opened and closed with a small window or the like, the window frame It can also be applied to vertical frames.

Here, FIG. 3 shows an outline of the application of the present invention to a threshold of one groove, and the separation cover members 2a and 2b are mounted on both sides of the planned groove portion 3 as shown in (a), and then as shown in (b). The groove 4 is cut at the edge of the separation cover members 2a and 2b. In this example, as shown in (c), the rail member 4a with the protruding flange portion is fitted into the groove portion 4.

FIG. 4 shows an outline of the invention of claim 1 applied to a sill of one groove. First, as shown in FIG. 5b (black portions in the figure) are continuously provided, and the separation cover members 2a and 2b are provided on both sides of the base member 1 with the groove 3 planned, and then the separation cover member as shown in (b). The groove 4 is provided between 2a and 2b, and when cutting, the excess portions of the cut margins 5a and 5b of the separation cover members 2a and 2b and the groove 4 are cut together. The cutting position is indicated by C ↓ in (a). The groove (4) can be used for mounting the rail member 4a having no flange.

FIG. 5 shows a case where the invention of claim 2 is applied to a threshold of one groove, and a part of the planned groove portion 3 in a state where the separation cover members 2a and 2b are mounted on both sides of the planned groove portion 3 as shown in FIG. Is cut into a state in which the preliminary groove 31 is provided, and then the groove 4 is cut at the edge of the separation cover members 2a and 2b as shown in FIG. In this example, as shown in (c), the rail member 4a with the protruding flange portion is fitted into the groove portion 4.
In this case, the preliminary groove may be provided in advance and then the separation cover member may be attached, or conversely, the preliminary groove may be provided after the separation cover member is attached.

FIG. 6 is an application of the invention of claim 3 to a threshold of one groove ,
First, as shown in (a), the groove of the base member 1 with the cut margins 5a and 5b (black portions in the figure) continuously extended to the planned groove portion 3 at opposite edges of the separation cover members 2a and 2b. The separation cover members 2a and 2b are covered on both sides of the planned portion 3, and the preliminary groove 31 is cut at the center of the planned groove portion 3, and then the separation cover member 2a, as shown in (b), The groove 4 is provided between 2b, and when cutting, the excess portions of the cut margins 5a and 5b of the separation cover members 2a and 2b and the groove 4 are cut together. The cutting position is indicated by C ↓ in (a). The groove 4 can be used for mounting the rail member 4a having no flange.

In this case, if the width of the cut margin is narrow and does not protrude into the preliminary groove, the preliminary groove may be applied in advance, and then the separation cover member may be mounted. However, if the cut margin is wide and at least part of the cut margin is projected onto the preliminary groove as shown in FIG. 7, the preliminary cover is provided first, and then the separation cover member is mounted.
5 and 6, both the depth and the width of the preliminary groove 31 are smaller than the final groove portion 4, but it is preferable that the depth matches the final groove portion 4. .

In addition, for example, even if it is a sill of 1 groove, the groove core is set near the center of the width, and if it is overlapped with the wall surface in accordance with the dust pulling method, the groove core is shifted to the opposite side of the wall. Thus, shifting the groove core in this way is a variation that is normally required even when the number of the grooves becomes two or more.
FIG. 7 shows a typical variation of the one-slot sill, in which (a) shows the case where the groove portion 4 is provided at the approximate center of the sill width, and (b) and (c) show either side. Therefore, even if one separation cover member having the same width is used, it is possible to cope with changes in the width of the member within the range close to the groove width.

  Fig. 8 shows the numerical value in millimeters for a typical sill variation of one groove. (A) is 55.5 mm wide, (b) is 54.5 mm wide, (c) is 48 mm wide. Yes, it is necessary to prepare separate cover members corresponding to each width according to the setting of each groove core, but after installing the cut margin in the separate cover member and attaching it to the base member, the excess part of the cut margin When cutting together with the cutting of the groove, it is possible to absorb variations in the range near the groove width as much as possible, and drastically change the number of parts and the number of molds required for the molding. For example, in the case of FIG. 8, if the outer edge dimensions are 22 mm, 24 mm, and 26 mm, the separation cover members are 21.5 mm, 19.5 mm, and 17.5 mm, respectively. Although it is necessary, in the present invention, it is possible to cope with one of 21.5 mm corresponding to a 26 mm groove core with a cut margin added. This is an example, even if there are two or more grooves, and even if there are many small variations, the cost can be greatly reduced by drastically changing these component types and the number of molds.

FIG. 9 shows an outline of the cutting of the groove portion 4, (a) shows the cutting of the groove portion 4 after the preliminary groove 31 is applied as in the present invention, and (b) shows the conventional groove portion 4 at a stretch. To cut.
In the conventional method, if the groove width is different, it is necessary to prepare the three-sided cutting cutters 101 having different widths accordingly, and the cutting waste of the groove portion 4 is generated at a stretch. The waste storage space must also be considered, but when the preliminary groove 31 is provided, the final cut of the groove portion 4 is performed by a two-sided cutting cutter 100 that forms a groove bottom while cutting each side of the preliminary groove 31. Therefore, even if the groove width is changed, it is advantageous to be able to cope with all with a kind of two-sided cutting cutter 100, the discharge device for cut waste can be downsized, and the accommodation space can be reduced.

  In the above description, the example of the single groove portion 40 has been described. However, even when the number of the groove portions 40 is two or more as shown in FIG. In (a), the separation cover member 2c between the planned groove portions 3 and 3 is set with cut margins 5c and 5c protruding from both sides to the predetermined groove portions 3 and 3 if necessary. 31 may be given. In this state, the separation cover members 2a, 2b, and 2c are attached to the base member 1, and then the grooves 4 and 4 are cut.

  The present invention is applicable to a grooved frame member of an opening frame forming member in various fittings such as sliding doors, doors, and hanging doors deployed in a building. Also, the number of grooves can be applied to a grooved frame member for installing multiple sliding doors from one pulling to two pulling or more.
