  As shown in FIGS. 8 and 9, the door frame 1 (sliding door frame) according to the present embodiment is attached to the opening 4 opened on the inner wall 5 of a building such as a residence. In this door frame 1, a single door body 2 (sliding door) for closing or opening the opening 4 is slidably disposed. In addition, FIG. 8 is each explanatory drawing of a door frame with a lower frame, and FIG. 9 is each explanatory drawing of a door frame without a lower frame.

  The door frame 1 is provided with at least frame frames 10 and 10 erected on both sides of the door body 2. The door frame 1 has a lower frame connecting member 30 for connecting the frame frames 10 and 10 to the lower frame 20.

  The lower frame connecting member 30 is attached to the floor installation surface 12 of the eaves frame 10 and arranged below the floor surface 7, and the eaves frames 10, 10 and the lower frame 20 are connected via the lower frame connecting member 30. A door frame with a lower frame can be formed by connecting with a fixing tool such as a screw 50 (bolt). On the other hand, a door frame without a lower frame can be formed without attaching the lower frame connecting member 30 to the floor installation surface 12 of the fence frame 10.

  As shown in FIG. 1, a lower frame connecting member 30 is attached to the lower end surface (floor installation surface 12) of the eaves frame 10, and a connecting plate 40 is attached to the end face of the lower frame 20 on the eaves frame 10 side. . Further, the lower frame connecting member 30 is formed with a female screw portion 32 (see FIG. 3C) that is screwed into a screw tool 50 inserted obliquely from above via a connecting plate 40 attached to the lower frame 20. Yes.

  Here, the door frame with the lower frame is the door frame 1 in which the lower frame 20 is connected to the frame 10. Further, the door frame without the lower frame includes those that do not install the lower frame 20 or those that are embedded in the floor even if the lower frame 20 is installed and do not require connection with the fence frame 10.

  As described above, the lower frame connecting member 30 attached to the frame 10 can be installed on the frame 10 or can be installed without being attached. That is, when forming as a door frame with a lower frame for sliding doors corresponding to FIG. 8, the lower frame connecting member 30 can be used as an additional member, and as a door frame without a lower frame such as for a suspension door corresponding to FIG. When forming, it may be used without using the lower frame connecting member 30.

  First, the connection structure of the frame 10 and the lower frame 20 in the X part of FIG. 8 when constructing the door frame 1 as a door frame with a lower frame for sliding doors will be illustrated and described.

  The door frame 1 shown in FIG. 8 includes an upper frame 3 installed on the ceiling side, a lower frame 20 installed on the floor side, and a pair of frame frames installed on the left and right sides of the upper frame 3 and the lower frame 20. 10 and 10 and a neutral stand 8 installed at a substantially central position between the eaves frames 10 and 10. In addition, the code | symbol 6 in FIG. 8 is a buttress wall.

  As shown in FIG. 1, the door frame 1 further includes a lower frame connecting member 30 attached to the frame 10 and a connecting plate 40 attached to the lower frame 20.

  As shown in FIG. 1, on the inner side surface (side surface (refer to FIG. 8) on the side where the door body 2 is arranged) of the frame 10, a door drill groove 11 that accommodates the end of the door body 2 on the door tip side. Is formed over the entire length. Although not shown in FIG. 1, the other side frame 10 shown in FIG. 8 is also formed with a door punching groove 11 that accommodates the door-side end of the door 2 over the entire length. The connection structure is the same as the structure of part X in FIG.

  As shown in FIG. 1, the door scraping groove 11 is formed to reach the lower end of the frame 10, and the portion corresponding to the door punching groove 11 (the cross in FIG. 2) on the lower end surface (floor installation surface 12). The lower frame connecting member 30 is attached to the hatched portion. Further, as shown in FIG. 2, a fitting recess 13 that fits with a coupling protrusion 37 of a lower frame connecting member 30 described later is formed on the outer surface of the lower end portion of the collar frame 10.

  On the other hand, the lower frame 20 is disposed between the lower ends of the collar frames 10 and 10. On the upper surface of the lower frame 20, as shown in FIG. 1, a door member (not shown) provided in the door body 2 (sliding door) is engaged, and a rail member 22 for guiding the sliding door is fitted. The sliding door groove 21 is formed over the entire longitudinal direction. Further, as described above, the connecting plate 40 for connecting to the collar frame 10 is attached to the end surface of the lower frame 20 on the collar frame 10 side.

  First, the structure on the side of the collar frame 10 relating to the connection between the collar frame 10 and the lower frame 20 will be described with reference to FIGS.

  The lower frame connecting member 30 is made of synthetic resin. Of course, a hard material other than the synthetic resin may be used as the material. As shown in FIGS. 3A to 3C, the lower frame connecting member 30 has a main body portion 31 whose appearance is generally a rectangular parallelepiped shape.

  An engaging portion that engages with the connecting plate 40 is formed on the inner surface of the main body 31 (the surface on the side surface of the frame frame 10 on which the door-scraping groove 11 is formed). The engaging portion is composed of three protruding portions, that is, two engaging small protrusions 38, 38 at both ends of the upper portion and a central protrusion 39 having a curved upper end at the center of the lower portion. These engage with engaging portions (engagement receiving portions 45, 45, 46) (see FIG. 6B) provided on the connecting plate 40 described later.

  An opening is formed in the upper part of the central protrusion 39 at the corner between the inner surface and the upper surface of the main body 31. This opening communicates with a screw insertion passage 33 formed obliquely downward toward the inner center of the main body 31. The screw insertion passage 33 is an insertion passage of the shaft portion 51 of the screw tool 50 inserted obliquely from above, and a female screw material made of a metal plate nut is internally provided in the space on the terminal side of the screw insertion passage 33. A portion 32 is formed. When the screw 50 inserted through the connecting plate 40 is screwed into the female screw material, the lower frame connecting member 30 and the connecting plate 40 are coupled.

  Further, the opening 31 a on the upper surface of the main body 31 is an opening for mounting the female screw material inside the main body 31. Thus, since it is the structure which attaches a plate nut to the lower frame connection member 30, the lower frame connection member 30 with an internal thread part can be shape | molded easily. The lower frame connecting member 30 with the female thread portion may be formed by two-color molding. In particular, since the lower frame connecting member 30 is made of synthetic resin, the female screw portion 32 can be easily formed in this way.

  As shown in FIG. 3C, a screw mounting hole 35 for a fixing screw 55 (see FIG. 7) is formed in the main body 31 so as to communicate from the lower surface to the upper surface. In addition, a screw head housing recess 36 that is connected to the screw mounting hole 35 and has a diameter larger than that of the screw mounting hole 35 is formed on the lower surface side of the main body 31.

  On the outer surface side of the upper surface of the main body 31, a coupling protrusion 37 that fits into the fitting recess 13 of the collar frame 10 is formed. As shown in FIG. 3B, the coupling protrusion 37 has a shape obtained by cutting out a circular lower end portion, and linear small protrusions 37a and 37a are formed at regular intervals on the outer peripheral portion thereof. .

  Such a lower frame connecting member 30 is attached to a predetermined portion (see FIG. 2) of the lower end surface 12 of the collar frame 10. The lower frame connecting member 30 is configured such that the coupling protrusion 37 is fitted into the fitting recess 13 of the frame 10 and is fixedly attached to the frame 10 with a fixing screw 55 (see FIG. 7) from below. It can be used as a frame material for frame.

  As shown in FIGS. 4 (a) and 4 (b), the fitting recess 13 of the collar frame 10 into which the coupling protrusion 37 is fitted is pressed against the small protrusions 37a and 37a of the coupling protrusion 37. The coupling protrusion 37 has a diameter that is substantially the same as or slightly larger.

  In this way, the lower frame connecting member 30 is fixed to the lower end portion of the collar frame 10 by screwing with the fixing screw 55 (see FIG. 7) and fitting of the coupling protrusion 37 into the fitting recess 13. It has become so. Therefore, it is possible to prevent the lower frame connecting member 30 from being displaced or detached after being attached. In particular, since the width dimension L1 of the lower opening 13a of the fitting recess 13 is smaller than the maximum width dimension L2 (corresponding to the diameter of a circle) of the coupling protrusion 37, the coupling protrusion 37 is opened downward. There is no risk of coming off 13a. In addition, you may make it screw with respect to the collar frame 10 from the outer surface of the protrusion part 37 for coupling | bonding in order to fix still more firmly.

  The shape of the fitting recess 13 and the coupling protrusion 37 is not limited to the shape shown in FIG. 4, and any shape can be used as long as the dimensional relationship between them is as described above. Good. Further, the coupling protrusion 37 is shaped so as to be able to be pulled out downward from the lower opening 13a of the fitting recess 13, and instead, a screw or the like is fixed to the flange frame 10 from the outer surface of the coupling protrusion 37. It is good also as a structure fixed with a tool.

  In this way, the lower frame connecting member 30 attached to the lower end surface 12 of the frame 10 is arranged below the floor surface 7 when the door frame 1 is constructed (see FIG. 4B).

  Next, the structure on the lower frame 20 side relating to the connection between the collar frame 10 and the lower frame 20 will be described with reference to FIGS. 1, 5, and 6.

  The connecting plate 40 attached to the lower frame 20 is made of synthetic resin. As shown in FIG. 5A, the connecting plate 40 has an elongated trapezoidal shape in plan view corresponding to the door punching groove 11 of the frame 10. That is, the connecting plate 40 is a spacer disposed in the gap space of the door-skin groove 11 between the end surface of the lower frame 20 and the bottom of the door-shear groove 11 when the lower frame 20 and the saddle frame 10 are connected. It is also a member that acts as.

  The lower frame 20 to which the connecting plate 40 is attached has a vertical cross section and an end surface as shown in FIG. At both ends in the width direction of the lower frame 20 (the prospective direction of the door frame 1), flanges 23 and 23 projecting on both sides are formed. The upper part of the lower frame 20 including the flange parts 23, 23 is arranged on the upper side of the floor surface 7 when the door frame 1 is constructed. That is, when the door frame 1 is constructed, a floor material (not shown) is fitted into each of the recesses 24 and 24 below the flange parts 23 and 23, and a virtual connection between the lower surfaces of the both flange parts 23 and 23 is performed. The lower part than the line (illustrated by a two-dot chain line) is arranged below the floor surface 7.

  On both sides in the width direction in the lower part of the lower frame 20 than the flange parts 23, 23, concave grooves 25, 25 for fitting the fruit (not shown) of the flooring material are formed. Further, at three positions on the lower surface side of the lower frame 20, thinned concave grooves 26, 27, 26 are formed. The central hollow groove 27 is an engaging concave portion for positioning when the connecting plate 40 is attached.

  The connecting plate 40 is a member that is directly connected to the lower frame connecting member 30, but its upper part is shaped to fit into the door-scraping groove 11 of the fence frame 10, and for that purpose, the upper part of the connecting plate 40. Is formed with a groove fitting portion 41 that matches the shape of the door punching groove 11 in plan view. The groove fitting portion 41 protrudes like the wings in the width direction from the main body portion 42 of the connecting plate 40.

  In addition, cut grooves 41 a and 41 a are formed at both ends of the groove fitting portion 41. By connecting the two connecting plates 40 cut off the outer side of either one of the cut grooves 41a and 41a to each other in the expected direction, the cut portions 41a and 41a can be made to correspond to the door punch groove 11 having a large width dimension. it can.

  The connecting plate 40 is provided with two screw mounting holes 47, 47 that pass through from the frame 10 side to the lower frame 20 side and are fixed to the lower frame 20. A guide insertion hole 43 penetrating from the lower frame 20 side to the flange frame 10 side is formed at a position corresponding to the opening at the end of the sliding door groove 21 at an intermediate position between the screw mounting holes 47 and 47.

  As shown in FIGS. 6A to 6C, the guide insertion hole 43 is directed from the lower frame 20 side (left side of the connecting plate 40 in FIG. 6C) to the flange frame 10 side (same right side). It is opened diagonally below. The guide insertion hole 43 is a guide hole through which the screw tool 50 is inserted into the screw insertion passage 33 of the lower frame connecting member 30 of the frame frame 10 when the door frame 1 is constructed. On the surface of the connecting plate 40 on the lower frame 20 side, a screw head housing recess 44 that is connected to the guide insertion hole 43 and has a diameter larger than that of the guide insertion hole 43 is formed.

  Further, on the surface of the connecting plate 40 on the side of the flange frame 10, engaging portions (engagement receiving portions 45, 38) that engage with the three engaging portions 38, 39, 38 formed on the lower frame connecting member 30. 46, 45) are formed (see FIG. 5C and FIG. 6B). Of these engaging portions, two engagement receiving portions 45 and 45 each having a square hole communicating with each of the screw receiving recesses 48 and 48 for fixing to the lower frame 20 are formed in the lower frame connecting member 30. The engagement receiving portion 46, which is an engagement portion corresponding to the engagement small protrusions 38, 38, and is formed of a recess provided in the lower center portion of the engagement portions, is formed in the lower frame connecting member 30. This is an engaging portion corresponding to the central protrusion 39.

  On the surface of the connecting plate 40 on the lower frame 20 side, there is formed an engaging protrusion 49 that engages with an engaging concave portion (thickening concave groove 27) provided on the lower surface of the lower frame 20 (FIG. 5 ( b) and FIGS. 6 (a) and 6 (c)).

  The hook frame 10 with the lower frame connecting member 30 described above and the lower frame 20 with the connecting plate 40 are connected by a screw tool 50 as shown in FIG.

  Specifically, the collar frame 10 and the lower frame 20 are coupled by being coupled in a state where the lower frame coupling member 30 and the coupling plate 40 are positioned by engagement of the engagement portions. In the coupled state, the screw insertion passage 33 and the guide insertion passage 43 form a linear screw insertion space into which the screw tool 50 can be inserted. The screw 50 is inserted into the screw insertion space from the opening on the connecting plate 40 side (screw head receiving recess 44) and screwed into the female screw portion 32, so that the collar frame 10 and the lower frame 20 are fixed to each other. Is done.

  In this way, the screw 50 is inserted into the lower frame connecting member 30 obliquely from above via the connecting plate 40 and screwed into the female screw portion 32 (female screw material), so that the screwing operation is easy. The door frame 1 can be constructed efficiently. Moreover, since it is screwed in the diagonal direction, the fixability is also good.

  Further, since the screw insertion passage 33 and the guide insertion passage 43 are provided to facilitate the insertion of the screw tool 50 from an oblique direction, the collar frame 10 and the lower frame 20 are separately provided in the opening 4 (FIG. 8). This is particularly effective when both frame members are connected after being attached to the reference).

  Moreover, since the connecting plate 40 is attached to the lower frame 20 and connected to the collar frame 10, workability at the time of assembling both members can be improved. Since the connecting plate 40 has a structure in which a part (groove fitting portion 41) is fitted to the door-skin groove 11, it is difficult for displacement to occur during the assembly work, and the fixing work with the screw 50 can be easily performed. . Further, since the connecting plate 40 is fitted into the door punching groove 11 and is disposed in the gap between the lower frame 20 and the frame 10, the aesthetic appearance is not impaired.

  Furthermore, since each of the lower frame connecting member 30 and the connecting plate 40 includes an engaging portion that engages with each other so that they can be positioned with respect to each other, the workability during the assembling work can be further improved.

  Moreover, since the internal thread part 32 screwed in the screw tool 50 penetrated from diagonally upward is formed in the inside of the lower frame connection member 30, a fixing operation can be performed smoothly. In particular, in the door frame 1 of the present embodiment, the guide plate insertion hole 43 through which the connection plate 40 is inserted into the screw insertion passage 33 of the lower frame connection member 30 is formed. 50 can be installed.

  It should be noted that the hook frame 10 and the lower frame 20 may be coupled to each other without using the screw tool 50 and using other fixing tools such as screws or nails. That is, the lower frame connecting member 30 may have a configuration in which the female screw portion 32 and the screw insertion passage 33 are not provided.

  As described above, the door frame 1 according to this embodiment forms the door frame with the lower frame as shown in FIG. 8 quickly without trouble by attaching the lower frame connecting member 30 to the frame frame 10. be able to.

  Moreover, since this door frame 1 becomes a structure which mounts the separate lower frame connection member 30 with respect to the collar frame 10, it can also use the collar frame 10 without attaching the lower frame coupling member 30. FIG. . That is, when the door frame 1 is constructed, the same frame 20 can be used regardless of whether the lower frame 20 is required. Moreover, since it is the structure used properly by attachment or detachment of the lower frame connection member 30, it is not necessary to cut the eaves frame 20. FIG.

  According to the door frame 1 that does not use the lower frame connecting member 30, as shown in FIG. 9, the lower frame 20 is not installed on the floor and the lower frame 2 (sliding door) is suspended and supported from the upper frame 3. A door frame can also be formed. Thus, the frame 10 of the door frame 1 has a lower frame connecting member 30 as shown in FIG. In other words, the entire floor installation surface 12 is installed in contact with the floor surface 7.

  Next, a door frame according to another embodiment of the present invention will be described with reference to FIG.

  The door frame 1 is different from the embodiment described above in the lower frame connecting member 30 attached to the lower end surface of the frame 10. Specifically, as shown in FIG. 10, a screw insertion passage 33 is formed in the lower frame connecting member 30, and a female screw portion 32 is formed in the screw insertion passage 33. That is, a screw groove is formed in the screw insertion passage 33.

  As described above, since the female screw portion 32 is formed in the screw insertion passage 33, most of the shaft portion 51 of the screw tool 50 is screwed into the female screw portion 32. Therefore, the connectivity between the collar frame 10 and the lower frame 20 can be further enhanced. A cylindrical female screw material may be arranged in the screw insertion passage 33.

  About the effect by the door frame 1 of this embodiment, and another structure part, since it is the same as that of the thing of embodiment mentioned above, those description and illustration are abbreviate | omitted.

  Although the door frame 1 which concerns on 2 embodiment shown above was illustrated as a thing for sliding doors, it cannot be overemphasized that it is applicable not only to them but a hinged door and a folding door.
