Description

  [Technical Field] The present invention relates to a structure for fixing to a floor surface of a center stand disposed in a vertical direction at an intermediate portion of a sliding door frame that slidably holds a sliding door, and a center stand.

  In general, a sliding door frame 101 of a building is arranged as a frame portion of an opening for a sliding door established on a wall or the like, and as shown in FIG. 7A, upper and lower horizontal frames 102 and 103 and left and right vertical frames 104 and 105. And a central stand 110 disposed up and down at a lateral intermediate portion.

  The center stand 110 has a structure including a center stand main body 111 having a vertical groove 111a on a side portion on the sliding door 106 side, and a gap blocking member 112 attached to the vertical groove 111a. The gap blocking member 112 is a gap between the center-standing main body 111 and the door plate surface of the sliding door 106 for ensuring the running performance of the sliding door 106, and without leaking light and air leakage. It is closed to prevent intrusion, and at least the side of the gap blocking member 112 on the sliding door 106 side is provided with a soft fiber material 112a such as mohair, for example.

  Conventionally, the technique of Patent Document 1 has been disclosed as the structure of the center stand 110 having such a gap blocking member 112.

JP 2007-239277 A

  By the way, such a middle stand 110 is erected at the center position after fixing the upper and lower horizontal frames 102 and 103 and the left and right vertical frames 104 and 105, and the lower end thereof is indicated by an arrow Z in FIG. As shown by, a fixing member 107 such as a screw or a nail is fixed to the floor surface by driving obliquely downward from the vicinity of the lower end of one side surface (on the narrow portion 103a side of the lower horizontal frame 103) of the central stand 110. . In that case, it is customary to fix the central stand 110 without being connected to the lower horizontal frame 103 so that the central stand 110 and the lower horizontal frame 103 can be individually removed.

  However, when the center stand 110 is fixed by driving the fixing member 107 from the side, the screw head is exposed in appearance, so that the appearance is not good. Further, since the driving is performed from the side in the sliding door traveling direction, the strength against the force transmitted from the sliding door is weakened along with the sliding door traveling, and there is a possibility that a lateral displacement (rotational displacement) due to the sliding door 106 traveling may occur. Moreover, since it was the structure fixed only in one place with respect to the large dimension side surface in consideration of aesthetics, the fixing strength as a whole was also weak.

  If the lower end of the central stand 110 is screwed at a plurality of locations from the side, the fixing strength will increase, but the aesthetics will become worse and more labor-intensive, so conventionally such a fixing method has not been adopted. .

  In addition, when the fixing member is driven from the side, the fixing member is penetrated to the lower horizontal frame by mistake in the driving direction, and the center frame and the lower horizontal frame are combined to be fixed to the floor surface. There was also a fear.

  Further, if the middle stand 110 is driven and fixed from the side opposite to that of the illustrated example (on the wide portion 103b side of the lower horizontal frame 103) and then the lower horizontal frame 103 is fixed, depending on the driving position, The screw head is concealed by the lower horizontal frame 103, and there is no possibility of being connected to the lower horizontal frame 103 by fixing the screw of the center stand 110. However, such a fixing method cannot position the center stand. It is not possible to adopt a simple method.

  The present invention has been proposed in view of such circumstances, and the purpose of the present invention is to improve the appearance of the fixing member when the center stand is fixed to the floor surface with a fixing member such as a screw and the head of the fixing member is not exposed. Another object of the present invention is to provide a center-standing fixing structure with excellent fixing strength.

  In order to achieve the above-mentioned object, the mid-standing structure of the present invention is arranged in the vertical direction at the middle part of the sliding door frame that slidably holds the sliding door, and is formed on the side part on the sliding door side of the central standing body. In a center-standing fixing structure that fixes a center stand made by attaching a gap blocking member to the vertical groove to the floor surface, a fixing member such as a screw is driven obliquely downward from near the lower end of the bottom of the vertical groove toward the floor surface. Then, the central stand main body is fixed to the floor surface, and a gap blocking member is attached to the fixed central stand main body.

  In the center-standing type fixing structure described in claim 2, the center-standing type main body is formed by fitting and fixing a resin block material having a guide hole portion for driving a fixing member in a recess at the lower end. .

  The center stand described in claim 3 is used for the center stand fixing structure described in claim 2.

  According to the present invention described in claims 1 to 3, a structure in which a fixing member such as a screw is driven obliquely downward toward the floor surface from the vicinity of the lower end of the bottom of the longitudinal groove to fix the center stand main body to the floor surface. Therefore, if a gap blocking member is formed in the longitudinal groove thereafter, the head of the fixing member driven in the vicinity of the lower end is hidden by the gap blocking member, so that the appearance is not deteriorated. Further, since the driving direction of the fixing member is a direction orthogonal to the sliding door traveling direction, the fixing strength against the force transmitted from the sliding door is improved with the sliding door traveling.

  Furthermore, since the fixing member is driven obliquely downward from the bottom of the vertical groove, there is almost no risk of the screw accidentally penetrating the lower horizontal frame, and it is ensured that the center stand is not individually connected to the lower horizontal frame by mistake. Can be fixed on the floor.

  According to the second and third aspects of the present invention, the resin block material in which the guide hole portion for driving the fixing member is inserted and fixed in the recess at the lower end of the center-standing main body is fixed. Since the main body is formed, it is possible to reliably drive a fixing member such as a screw in the expected direction, and it is easy to drive the fixing member, thereby reducing labor.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is an explanatory view of an embodiment of a center-standing fixing structure of the present invention, FIG. 1 (a) is a perspective view of a sliding door frame, and FIG. 1 (b) is a structure for fixing a center-standing main body to a floor surface. FIG. 2 is a partial perspective view (corresponding to a portion X in FIG. 1A). FIG. 2 is a perspective view of the sliding door frame as viewed from the opposite direction to FIG. FIG. 3 is a cross-sectional view of the sliding door frame. FIG. 4A is an exploded partially broken front view of a center stand, and FIG. 4B is an exploded bottom view thereof. FIG. 5A is an enlarged view of the fractured portion of FIG. 4A, and FIG. 5B is a view of the resin block material viewed from the direction of arrow A in FIG. 5A.

  The sliding door frame 1 is made of a wood material or the like, and is disposed as a frame portion of an opening for the sliding door 6 established on a wall or the like. As shown in FIGS. 1 to 3, the upper and lower horizontal frames 2, 3, A vertical frame is provided, and a central stand 10 is provided that is disposed vertically in the horizontal intermediate portion. In the following, regarding the left and right vertical frames, the left one in FIG. 1 is referred to as a narrow vertical frame 4, and the right one is referred to as a wide vertical frame 5. Note that the sliding door frame 1 including the central stand 10 may be made of a metal material such as aluminum.

  The sliding door frame 1 is constructed by connecting the left and right ends of the upper horizontal frame 2 and the lower horizontal frame 3 with a narrow vertical frame 4 and a wide vertical frame 5 respectively, and extending the sliding door over almost the entire length of the upper horizontal frame 2 and the lower horizontal frame 3. A running groove (only the running groove 3b of the lower horizontal frame 3 is shown) is formed so that 6 can be slid (runned).

  The upper and lower horizontal frames 2 and 3 are cut out from the connecting end to the center with the narrow vertical frame 4 in accordance with the width of the narrow vertical frame 4, and the wide of the notches 2a and 3a is wide. The center stand 10 is disposed at positions adjacent to the portions 2b and 3b so that the upper and lower ends are arranged.

  In the schematic cross-sectional view shown in FIG. 3, reference numerals 7 and 8 denote columns and face materials that form a hollow wall in the vicinity of the sliding door frame 1.

  Thus, the center stand 10 arranged in the center of the sliding door frame 1 includes a center stand main body 11 having a vertical groove 11a on the side portion on the sliding door 6 side, and a gap blocking member 12 attached to the vertical groove 11a. It is configured (see FIG. 4). This gap blocking member 12 is a gap between the center-standing main body 11 and the door plate surface of the sliding door 6 to ensure the running performance of the sliding door 6 without leaking light and air leakage. A soft fiber material 12b such as mohair is attached to at least a side portion of the main body 12a of the gap blocking member 12 on the sliding door 6 side so as to prevent intrusion.

  First, the center-standing main body 11 is arranged at the above-described center position of the already fixed upper and lower horizontal frames 2 and 3, and in this state, the lower end of the bottom portion 11aa of the vertical groove 11a to which the gap blocking member 12 is not yet mounted. A fixing member 9 such as a screw is driven obliquely downward (in the direction of arrow Y) from the vicinity toward the floor surface, and is fixed to the floor surface (see FIG. 1B).

  Then, the gap blocking member 12 is attached to the vertical groove 11a of the fixed central stand main body 11, and the attachment of the central stand 10 is completed (see FIG. 4). Note that the gap blocking member 12 is preferably attached to the vertical groove 11a by being fixed with an adhesive or the like, or attached so that the protrusion can be adjusted.

  Thus, since the fixing member 9 is driven obliquely downward from the bottom 11aa of the longitudinal groove 11a and the center-standing main body 11 is fixed to the floor surface, the head of the fixing member 9 is fixed to the floor surface. It is hidden by the gap blocking member 12 to be mounted. Therefore, there is no possibility that the aesthetics will be deteriorated.

  Further, since the fixing member 9 is driven into the bottom portion 11aa of the vertical groove 11a in the digging direction of the vertical groove 11a (the prospective direction, the thickness direction of the sliding door), it is strong against the force transmitted from the sliding door as the sliding door 6 travels. For example, there is no possibility that the center-standing main body 11 is not rotated due to the sliding door 6 traveling. In addition, the fixing member 9 is driven in one place, but since the structure is driven from the side in the expected direction with a small size along the direction of both side surfaces with the large size (expected direction), the expected direction is also included. Thus, strength in various directions can be obtained. A plurality of fixing members 9 may be driven from the bottom 11aa of the vertical groove 11a.

  Further, since the fixing member 9 is driven obliquely downward in the prospective direction, if the fixing member 9 is driven in parallel to both side surfaces of the sliding door 6 traveling direction, the screw does not penetrate the lower horizontal frame 3, and the middle stand 10 is moved to the lower horizontal frame. 3 can be individually fixed to the floor without being connected.

  In addition, when the center-standing main body 11 is formed of a metal material, an insertion hole is formed in the bottom 11aa of the longitudinal groove 11a, and a guide hole portion that can guide the penetration of the fixing member is formed in advance. Although desirable, as shown in FIG. 4 and FIG. 5 of the present embodiment, it is desirable that the lower end portion of the center stand 10 into which the fixing member is driven is constituted by another member.

  The lower end part structure of the center stand main body 10 comprised including another member is demonstrated referring FIG. 4 and FIG.

  A recess 11b is formed at the lower end of the center-standing main body 11, and a resin block material 11d is fitted and fixed in the recess 11b by dowel bonding, adhesive bonding, or the like.

  This resin block material 11d is made of hard resin, and a guide hole portion 11da for driving the fixing member 9 is formed. This guide hole portion 11da is a through hole, and there is an insertion port 11daa for the fixing member 9 at the bottom portion 11aa of the vertical groove 11a, and an outlet 11dab on the floor surface side.

  Since the guide hole portion 11da is thus opened, the fixing member 9 can be easily driven and can be driven to the correct position, and the construction time at the site can be shortened. 9 does not penetrate and mistakes can be eliminated.

  In particular, when the centrally standing main body 11 excluding the resin block material 11d is made of a metal material, the field work is remarkably performed by attaching the resin block material 11d to the centrally standing main body 11. It can be done easily.

  Further, the guide hole portion 11da may be a hole with a bottom as shown in FIG. Further, as shown in FIG. 6 (b), even in the guide hole portion 11da that can penetrate the wood portion 11c of the central stand main body with a screw or the like to enhance the connectivity with the wood portion 11c of the resin block material 11d. Good.

  Although the lower end fixing structure for the floor surface of the center stand 10 has been described above, the fixing member can be driven obliquely upward from the bottom portion 11aa of the vertical groove 11a and fixed to the ceiling portion similarly.
