Description

  The present invention relates to a door mounting bracket, and more particularly to a door mounting bracket installed in a large wooden building such as a mountain gate.

  In general, doors of detached houses, condominiums, hotels, apartments, etc. open and close and support the doors by hinges attached to the doors and door frames. On the other hand, in the case of a gate of a large building where the weight of one door exceeds 400 kg, a hinge having a small load bearing capacity cannot be used, and a metal fitting that combines an elbow metal fitting and an elbow metal fitting is used. . The metal fittings are provided with bearings that serve as bearings, and are fixed to the upper and lower crosspieces of the door of the door frame, respectively, and the elbow fittings are provided with shafts, which are fixed to the upper and lower ends on one side of the door, A shaft portion protruding from the elbow fitting is rotatably inserted into the bearing portion of the saddle fitting. For example, when building a door (gate) in the construction or repair of a large wooden building such as a mountain gate, fix the metal fittings with circular bearings on the crossbars above and below the door, An elbow fitting having a shaft portion protruding in a columnar shape is fixed to the upper end and the lower end of one side of the door, and the shaft portion protruding from the elbow fitting is rotatably inserted into the bearing portion of the saddle fitting. The door is opened, closed, and supported by the elbow arm. In addition, the rung above the door may be referred to as a duck or a crown, and the rung below the door may be referred to as a sill or a garage.

  Doors and door frames of large wooden buildings such as the above-mentioned mountain gates can be opened and closed because the door installation position fluctuates due to distortion due to aging of wood, loads due to loads, and other natural disasters. May cause trouble. However, the weight of one door of these large wooden buildings exceeds 400 kg (some of them have a length exceeding 8 m), and for repairing the door construction (installation position adjustment) The heavy doors must be removed using heavy machinery, and a lot of manpower is required. Therefore, it is very difficult to repair the doors of large wooden buildings.

The following are known techniques relating to the installation position adjustment of doors (gates) that have already been disclosed. Patent Document 1 describes a configuration in which the base of the shaft of the gate door is U-shaped and fitted to the door, and slides in the width direction (FIG. 6 and the like). Further, Patent Document 2 describes a configuration in which a bearing portion that protrudes in the horizontal direction from the gate pole side slides in the horizontal direction (FIG. 1 and the like). Patent Document 3 describes a configuration in which an adjustment screw is screwed onto the outer surface of the bearing portion on the door frame side and the position is adjusted in the horizontal direction (FIG. 2 and the like). In Patent Document 4, a vertical adjustment nut is incorporated in the bolt portion of the door side plate shaft center of the door frame lower pivot so that the door side plate is sandwiched between two nuts, and the upper nut of the door side plate is increased. A configuration is described in which the installation adjustment in the vertical direction is made possible by loosening and rotating the lower vertical adjustment nut upward to lift the door side plate (FIG. 3 and the like).

  However, in the above conventional door mounting brackets, the doors (gates) of ordinary houses and the like are hinges called pivot hinges (Patent Documents 2 to 4) and drawer plates having shaft support holes (Patent Document 1). Because the door shaft center is pulled out in the horizontal direction to support the door, a load exceeding the door weight may be applied to the hinge or drawer plate according to the length of the door shaft core In addition, it is difficult to obtain the strength to support a heavy door with a hinge or the like (Patent Documents 1 to 4). On the other hand, doors and door frames of large wooden buildings such as the above-mentioned mountain gates will change the position of the door due to the effects of distortion, twisting and loading due to aging of the wood, and other natural disasters. The phenomenon causes unpredictable and complicated distortion and twist. In addition, it may be temporarily distorted or twisted, but it may gradually change over time, which causes misalignment between the door and its frame, causing the door to bend and hinder opening and closing. Even came.

  Therefore, the object of the present invention is to adjust any misalignment with the door or door frame (mounting side) of a large wooden building such as a mountain gate (the position of the building can be adjusted). It is to provide a door mounting bracket that can be realized while planning.

  The door mounting bracket according to claim 1 of the present invention includes a door and a door frame to which the door is attached, and the door frame is installed on a large wooden building such as a mountain gate having a cross and a pillar. In the mounting bracket, the elbow bracket that is attached to the lower side of the door, the saddle bracket that is attached to the upper side of the crosspiece placed under the inner side of the door frame on which the door is attached, and a separated state between them. A cylindrical member that has a cylindrical one-side bearing that receives one side of the adjusting shaft member, and the saddle bracket receives the other side of the adjusting shaft member The adjustment shaft member is a cylindrical shape that is removably inserted and fitted into the cylindrical bearing portions of the elbow fitting and the saddle fitting, and the adjustment shaft member is A cylindrical core with a threaded outer periphery and a cylindrical shape with a larger outer diameter than the core The lower part formed and a plate whose inner periphery is threaded and screwed to the core, the screwing position of the core and the plate can be adjusted, and the cylindrical inner diameter of the one-side bearing part of the elbow fitting Is formed to be slightly larger than the outer diameter of the core formed on the upper side of the adjustment shaft member, and the depth of the bearing portion is formed to be larger than the height of the core, so that the upper surface of the plate becomes Although it contacts the lower end surface of the bearing part, the upper surface of the core is set so as not to contact the bottom surface formed on the cylindrical upper side of the bearing part.

  According to the present invention, by adjusting the screwing position (height position) between the plate and the core, the height position of the plate changes by the pitch of the screw in one round of the screw. The position can be adjusted. In addition, a spanner groove or a bar wrench hole for hooking a spanner or a bar wrench is formed on the core and the plate, respectively, so that the installation adjustment of the height position of the door is facilitated.

  The door mounting bracket according to claim 2 of the present invention is the adjusting shaft member in which a flat surface portion is formed on one side bearing portion of the elbow bracket, and a downward curved surface portion is formed on the lower side. Or a curved surface portion convex upward is formed on one side bearing portion of the elbow bracket, and a flat surface portion is in contact with the adjustment shaft member formed on the lower side, or the elbow bracket A convex curved surface portion is formed on the one side bearing portion, and a downward convex curved surface portion is in contact with the adjustment shaft member formed on the lower side.

  According to the present invention, by interposing an adjusting shaft member in a state where the both members of the heel bracket and the elbow bracket are separated, the stability fitted to the bearing portion of the heel bracket and the elbow bracket is achieved. However, it has the effect of flexibly responding to the strain and torsion and sufficiently absorbing them, and facilitating replacement of parts. That is, according to the present invention, for example, even when the door is distorted or twisted due to aging (even if the center load of the door shaft is displaced), the curved surface contact state with respect to the flat surface portion, the curved surface portion Depending on the contact state of the flat surface portion with respect to the curved surface portion and the contact state of the curved surface portion with respect to the curved surface portion, the adjustment shaft member is inclined by the amount of the distortion or twist. In other words, the tilt angle is absorbed so as to follow the temporal change with respect to the constantly changing strain or twist. Then, by adopting the tilt mechanism by the curved surface portion on both the one side (upper end surface) and the other side (lower end surface) of the adjusting shaft member, the shaft member is fitted to the bearing portion of the metal fitting and the elbow fitting. Even in such a state, the inclination angle by the curved surface portion can be adjusted. It should be noted that the relationship between the flat surface portion and the curved surface portion can be established only with both the metal fittings and the elbow metal fittings, but the adjustment of the state where the metal fittings and the elbow metal fittings are separated from each other than in this case. By interposing a shaft member for use, it is possible to absorb these sufficiently flexibly according to the size of the distortion and torsion, while maintaining the stability of fitting to the bearings of the metal fittings and elbow fittings. In addition, there is an effect that parts can be easily replaced.

  In the door mounting bracket according to the present invention, an eccentric member formed at a position where the outer peripheral portion and the inner peripheral portion are eccentric is incorporated in at least one of the bearing portions. It is preferable that it is detachably attached. According to the present invention, since the inner peripheral portion or the outer peripheral portion of the eccentric member is formed at an eccentric position, even if the door position deviates from the initial setting position, the door adjustment (the shaft position Adjustment) becomes possible.

  In the door mounting bracket according to the present invention, the elbow bracket includes a rail guide attached to the one-side bearing portion and a guide rail of an L-shaped bracket fixed to the door, and the position of the door is one of the L-shaped brackets. It is preferable to be configured to be adjustable along the side. According to the present invention, the position of the door can be adjusted to the left and right by mounting the elbow bracket movably through the guide rail of the L-shaped bracket to which the door is fixed.

  These door mounting brackets of the present invention are installed on the doors of large wooden buildings such as mountain gates, so that the doors can be easily removed without removing the heavy doors using heavy machinery or the like, and without much manpower. Repair (adjustment of the installation position) will be possible.

According to the present invention, the adjusting shaft member includes a core threaded on one side and a plate threaded on the outer periphery of the core, and the plate is below the bearing portion. The height position of the lower end surface of the bearing portion can be finely adjusted by contacting the end surface. Even when the upper and lower ends of the door are twisted, the adjusting shaft member absorbs the distortion and twist of the door in relation to the elbow bracket and the hook bracket. Therefore, it is possible to prevent a situation in which the opening and closing is hindered. In particular, by interposing an adjustment shaft member in a state where both the arm bracket and the elbow bracket are separated, the above-mentioned distortion is achieved while maintaining stability inserted into the bearing portion of the arm bracket and the elbow bracket. In addition to flexibly responding to the size of the torsion and absorbing them sufficiently, there is an effect that the parts can be easily replaced.
By using the eccentric member, the position of the shaft of the door can be adjusted, and the bearing portion is movably attached via a guide rail of an elbow fitting fixed to the lower end of the door. Since the door axis can be adjusted to the left and right, according to the door mounting bracket of the present invention, the door is adjusted to any position in the three-dimensional direction (up / down, left / right, front / rear, and adjustment of the axis position). be able to.

  The adjusting shaft member Hpj1 is interposed between the elbow fitting H1 and the saddle fitting U1, and is a cylindrical member. The shaft member Hpj1 for adjustment according to the present embodiment has different diameters in the upper part hpa and the lower part hpb, and the lower part hpb is larger in outer diameter than the upper part hpa in consideration of stability. Is formed in a large convex shape. Here, to explain the relationship between the upper part hpa and the lower part hpb, the curvature of the lower part hpb can be made smaller than the curvature of the convex curved surface part q on the upper part hpa side. In the case where the lower end surface hpb is the plane portion p, the twist and distortion on the upper portion hpa side can be reduced and the twist and distortion correction can be reduced on the lower end surface hpb side. In the convex adjustment shaft member Hpj1, the absorption of torsion and distortion can be adjusted by the difference in diameter between the upper part hpa and the lower part hpb. On the contrary, the lower part hpb may have an outer diameter smaller than that of the upper part hpa, or may be the same size without changing the size (single cylinder), depending on the implementation. Is possible.

The mountain gate 1 includes left and right double doors T1 and T2, an upper cross Y1 and a lower cross Y2 forming a door frame, left and right pillars G1 and G2, and mounting brackets X1 installed at four locations inside the door frame. Consists of The comparative door mounting bracket X1 includes four vertical brackets Xu fixed to the upper cross Y1 and the lower cross Y2 of the left and right double door T1 (T2), and one upper end of the door T1 (T2). There are four elbow brackets Xh fixed to Ta and the lower end Tb, respectively, and the shaft portion Xpj protruding from the elbow bracket Xh is rotatably inserted into the bearing portion Xuk of the flange bracket Xu (FIGS. 12 and 12). 13). The hook metal Xu has a structure in which a hook Xud having an outer diameter larger than that of the cylinder Xut is integrally formed on one side of the cylinder Xut (FIG. 13), and a plurality of screw holes Xn1 processed into the hook Xud are provided. The screws n1 are respectively fixed to the crosspieces Y1 and Y2 in which holes having the same size as the cylinder Xut are formed in advance. The elbow bracket Xh has a configuration in which a shaft portion Xpj is integrally formed on one side of the L-shaped bracket XL (FIG. 13), and is screwed by a screw n2 through a plurality of screw holes Xn2 formed in the L-shaped bracket XL. The door T1 (T2) is fixed to the upper end Ta and the lower end Tb on one side, respectively.

  14 (a) and 14 (b) are cross-sectional views schematically showing the mounting bracket X1 of the comparative example extracted from the one-dot chain line circle of FIG. When the twist θ is not generated at the upper end Ta and the lower end Tb on one side of the door T1 (T2), the central axis Ph-Ph of the shaft portion Xpj of the elbow fitting Xh is the central axis of the bearing portion Xuk of the fitting Xu. Since it matches (overlaps) Pu-Pu, there is no hindrance to opening and closing the door T1 (T2) (FIG. 14A). On the other hand, when the twist θ is generated at the upper end Ta and the lower end Tb on one side of the door T1 (T2), the center axis Ph-Ph of the shaft portion Xpj of the elbow bracket Xh is the same as that of the bearing portion Xuk of the bar bracket Xu. Since it is twisted by an angle θ with respect to the central axis Pu-Pu, when opening / closing the door T1 (T2), the shaft portion Xpj collides with the bearing portion Xuk, and this twist θ is caused by the mounting bracket X1. Since it cannot be absorbed, the door T1 (T2) crawls and obstructs opening and closing (FIG. 14B). For this reason, it is conceivable to reduce the depth of the bearing portion Xu of the metal fitting Xu, or to taper the vicinity of the entrance, but there is a risk that the shaft portion Xpj falls out of the metal fitting Xu. On the other hand, in this embodiment, the metal fittings U1, U2 and the elbow fittings are provided by interposing an adjusting shaft member in a state where the metal fittings U1, U2 and the elbow fittings H1, H2 are separated from each other. While maintaining stability when fitted to the bearings Hph and Uk of H1 and H2, they can flexibly accommodate the above distortion and torsion, absorb them sufficiently, and adjust the height and move eccentrically. And the effect of facilitating part replacement.

  As described above, in the present embodiment, the mounting brackets Z1 and Z2 have been described as examples of installation on the doors T1 and T2 that are opened on both sides of the mountain gate 1, but the present invention can also be applied to single-sided doors and folding doors. Moreover, the mounting brackets Z1 and Z2 of the present invention can be applied not only to large wooden buildings but also to large buildings having large and heavy doors. Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.
