Description

  The present invention relates to a bearing fitting for mounting a gate on a support column or a cage so that the gate is rotatably mounted.

  The gate provided on the side of the passage of each door of a detached house or apartment, for example, has a structure in which a frame-like part is attached inside the outer frame part of a predetermined shape, and the vertical direction of the outer frame part One side edge part is attached to a support | pillar or a cage | basket via the bearing metal fittings for gate attachment. Among the bearing fittings for gate installation, what is called a pivot hinge is a body that has an arm part that protrudes to the side of the column and a mounting part that is fixed to the column, etc., and an arm part that stands perpendicular to the protruding direction. It is composed of a cylindrical support shaft. Then, as shown in FIG. 8 (a), the bearings of the holding members 2 a and 2 b attached to the gate 1 are supported on the main bodies 5 a and 5 b of the bearing fittings 4 a and 4 b attached to the column 3. The shafts 6a and 6b are rotatably fitted, and the gate 1 is hung from the shaft and held openably and closably.

  In the bearing fitting for mounting the gate door, when the plurality of bearing fittings 4a and 4b are attached to the column 3, it is not easy to make the axes of the support shafts 6a and 6b completely coincide with each other, as shown in FIG. As shown in FIG. Therefore, conventionally, a pivot hinge having a function of finely adjusting the position of the support shaft after the main body of the bearing fitting is attached to the support column has been used. This type of pivot hinge includes a case portion fixed to a support column, a support arm member having a support portion fixed to the inside of the case member, and a portion protruding from the case member of the support arm member perpendicular to the protruding direction. It is comprised with the provided cylindrical spindle. For example, the hinge for gate attachment disclosed in Patent Documents 1 and 2 adjusts the protruding amount of the supporting arm member with respect to the case portion by turning a predetermined adjusting screw, or moves the supporting arm member in the protruding direction. It has a structure in which it is horizontally moved in the direction perpendicular to it. Therefore, it is possible to easily adjust the position in the XY directions to bring the gate position relative to or away from the column. Furthermore, the hinge of patent document 2 has a structure which can change the angle of the support arm member hold | maintained so that a swing is possible with respect to a case part with a predetermined | prescribed adjustment screw.

  Further, as disclosed in Patent Document 3, a bearing shape member used for a connecting portion such as a double-folded door, and a pocket-type bearing in which a shaft extending from the door fits inside is extruded. There is a bearing profile in which a plurality of protrusions that are in contact with the outer peripheral surface of the shaft are formed by continuously providing a concave notch having a predetermined shape on the inner peripheral surface of the bearing. This bearing profile reduces friction by reducing the area of the sliding contact surface with the outer peripheral surface of the shaft, suppresses the generation of squeaking noise (abnormal noise) during opening and closing operations, and smoothes the door opening and closing operations. To.

  If the mounting surface of the column or the like is twisted or not flat, the axial displacement between the upper and lower two mounting brackets becomes significant when the column is mounted on the column or the like. In particular, when an unfamiliar worker attaches it, it is difficult to completely cancel the shaft misalignment even if the adjustment function of the hinge for attaching the gate disclosed in Patent Documents 1 and 2 is used. Therefore, depending on the state of the mounting surface such as the support column, there is a problem that abnormal noise occurs due to friction between the outer peripheral surface of the support shaft and the inner peripheral surface of the holding member, and the gate cannot be opened and closed smoothly. .

  Moreover, even if the technique disclosed in Patent Document 3 is applied to the hinges of Patent Documents 1 and 2, it has not been possible to solve problems of generation of abnormal noise and smoothness of opening and closing.

  The present invention has been made in view of the above-described background art, and an object thereof is to provide a gate fitting for mounting a gate that can smoothly open and close the gate and generate less noise.

  The present invention provides a main body fixed to an attachment to which a gate is attached, and a holding member fixed to the gate, wherein the main body is erected perpendicularly to the protruding direction at a portion protruding to the side of the attachment. A cylindrical support shaft that is rotatably fitted to the bearing portion, and is a bearing fitting for mounting the gate to the attached object so as to be rotatable, and the outer peripheral surface of the support shaft is made of carbon. It is a bearing fitting for gate installation formed of the contained synthetic resin.

  A receiving surface for supporting the opening end surface of the bearing portion of the holding member from below is provided at the base portion of the support shaft, and the receiving surface is formed of a synthetic resin containing carbon.

  The support shaft is integrally formed with the synthetic resin together with a flange portion extending outward from a cylindrical end portion and attached to the main body, and the receiving surface is formed on the upper surface of the flange portion.

  Formed on the outer peripheral surface of the support shaft is a streak-like projection that slidably contacts the inner peripheral surface of the bearing portion and fits into the holding member. The streak-like projections may be a plurality of projections extending in the longitudinal direction on the cylindrical side surface and arranged at equal intervals, and a plurality of projections circling the cylindrical side surface may be arranged at equal intervals. Alternatively, it may be formed in a spiral shape in the longitudinal direction of the columnar shape. Further, the receiving surface is formed with a streak-like projection that is in sliding contact with the opening end surface of the bearing portion and supports the holding member.

  Further, the support shaft and the flange portion are provided with a hollow portion that communicates from the outside of the flange portion to the inside of the support shaft, and the support portion is reinforced to the hollow portion in a state of being fixed to the main body. A shaft rod is inserted.

  The bearing bracket of the present invention is a friction that occurs on the sliding contact surface between the holding member and the support shaft, wherein the outer peripheral surface of the support shaft that fits into the bearing portion of the holding member attached to the gate is formed of a synthetic resin containing carbon. Resistance is greatly reduced. Therefore, even if a plurality of bearing fittings are attached to a support column and the axis of the support shaft is slightly deviated, the gate can be opened and closed smoothly, and the generation of abnormal noise can be suppressed.

  Also, if the main body of the bearing bracket is composed of a case member and a support arm member, and the fixing position of the support arm member and the case member is made variable, even after attaching the plurality of bearing bracket main bodies to the support column, The shift of each spindle can be easily adjusted. In addition, if predetermined streak protrusions are provided on the outer peripheral surface of the support shaft and the receiving surface of the base portion, the frictional resistance between the bearing portion, the outer peripheral surface and the receiving surface is further reduced, and the noise generated by the friction is diffused. An effect is also obtained. Therefore, the opening / closing operation of the gate becomes smoother, and the effect of suppressing abnormal noise is further improved.

  Hereinafter, an embodiment of a bearing fitting for mounting a gate according to the present invention will be described with reference to FIGS. The bearing fitting 10 of this embodiment is attached to the support column 3 in the same manner as the conventional bearing fittings 4a and 4b shown in FIG. 8A, and is freely rotatable on the bearing portions of the holding members 2a and 2b attached to the gate door 1. It is a kind of pivot hinge that fits and supports the gate 1 in a freely rotatable manner.

  As shown in FIGS. 1A and 1B, the bearing fitting 10 includes a case member 12 that is a main body, and a support arm member 14 that is fixed to the case member 12 so that the position thereof can be adjusted. The case member 12 has a rectangular outer shape that is long in one direction and includes a middle wall 16 and a pair of side walls 18 and 20 that extend substantially at right angles to both ends thereof, and one side surface that is located at one end in the longitudinal direction. It is opened and becomes the insertion port 22 through which the support arm member 14 is inserted.

  A plate-like mounting portion that is continuous with the insertion opening 22 and that faces substantially parallel to the intermediate wall 18 is also opened. The plate-like attachment portion is continuous with the opening edge and extends laterally at a right angle to the side walls 18 and 20. 24 and 26 are provided. The attachment portions 24 and 26 are attached to the support column 3 so as to have a pair of screw through holes 24a and 26a. Triangular plate-like reinforcing portions 24b and 26b that are in contact with the side walls 18 and 20 at right angles are provided at the insertion port 22 side of the mounting portions 24 and 26 and the opposite ends thereof, respectively. Further, one side surface of the case member 12 located at one end opposite to the insertion port 22 is closed by the back wall 28.

  Inside the case member 12, a rod-like support arm member 14 is inserted in the direction from the insertion port 22 toward the back wall 28. The support arm member 14 includes a support portion 32 having a substantially rectangular cross-sectional shape with respect to the longitudinal direction. A support shaft standing portion 34 is integrally provided at an end portion of the support portion 32 that protrudes outward from the insertion port 28 of the case member 12. The support shaft standing portion 34 is provided with a support shaft mounting recess 34 a that is dug substantially perpendicularly to the upper surface of the support portion 32. The support shaft mounting recess 34a is provided so as to be able to be fitted with a fitting convex portion 44 extending on the base side of the support shaft 30 described later.

  The support arm 14 is fixed to the case member 12 by the first adjustment bolt 36 and the second adjustment bolt 38, and has a structure in which the fixing position with respect to the case member 12 can be adjusted. The first adjustment bolt 36 is held in a state in which the screw head is substantially in contact with the outer wall of the back wall 28, and the bolt portion is inserted into a through hole provided in the back wall 28 so that the end of the support arm member 14 on the support portion 32 side. It is screwed into a thread groove provided in the part. The second adjustment bolt 38 is held in a state where the screw head is substantially in contact with the outer wall of the side wall 20, the bolt part is inserted into a through hole provided in the side wall 20, and when the second adjustment bolt 38 is tightened, the tip of the screw part The support portion 32 of the support arm member 14 is sandwiched between the support 18 and the side wall 18. Accordingly, the support arm member 14 can be tilted about the screw head portion of the first adjustment bolt 36 with the second adjustment bolt 36 loosened, and the case member can be adjusted by adjusting the tightening amount of the first adjustment bolt 36. The length of the support arm member 14 protruding from the 12 insertion holes 22 also changes. By this operation, the position of the support shaft standing portion 34 can be varied, and the position of the support shaft 40 described later can be adjusted.

  The support shaft 40, the fitting convex portion 44, and the flange portion 46 shown in FIG. 1 are integrally formed of a synthetic resin containing carbon. The synthetic resin containing carbon can provide a predetermined flexibility while supporting the gate 1 while having a certain level of strength or more, and the surface friction resistance is smaller than that of a metal (for example, stainless steel or aluminum). It is a material that can be suppressed. It also has the effect of absorbing vibrations that cause abnormal noise.

  The support shaft 40 is a portion corresponding to the support shafts 6a, 6b of the conventional bearing fittings 4a, 4b shown in FIG. 8, and as shown in FIG. A streak-like protrusion 42a is formed in which a plurality of protrusions extending in the direction are arranged at equal intervals. At the base portion of the support shaft 40, a fitting projection 44 is provided that is fitted and fixed in the support shaft mounting recess 34a of the support shaft erecting portion 34. Further, a flange portion 46 is formed at the boundary portion between the outer peripheral surface 42 and the fitting convex portion so as to spread outward substantially horizontally. On the receiving surface 48 which is the upper surface of the flange portion 46, the streak-like projections 48a that radially extend the streak-like projections 42a are formed.

  As shown in FIG. 3, the support shaft 40 is fixed in a state where the fitting convex portion 44 is inserted deeply into the support shaft mounting recess 34a and the lower surface of the flange portion 46 is in contact with the opening end surface of the support shaft mounting recess 34a. The When the support shaft 40 is attached to the bearing portions of the holding members 2a and 2b shown in FIG. 8 of the counterpart, the streak protrusions 42a on the outer peripheral surface 42 come into sliding contact with the inner peripheral surface of the bearing portion, and the streaks of the receiving surface 48 The protrusion 48a is in sliding contact with the opening end surface of the bearing portion and supports the holding members 2a and 2b from below.

  As described above, the bearing fitting 10 is in sliding contact with the outer peripheral surface 42 including the streaky protrusion 42a of the support shaft 40 that is in sliding contact with the bearing portions of the holding members 2a and 2b attached to the gate 1, and the opening end surface of the bearing portion. The receiving surface 48 including the streaky protrusion 48a of the flange portion 46 is formed of a synthetic resin containing carbon. Therefore, the frictional resistance generated on the sliding contact surface between the holding members 2a and 2b and the support shaft 40 is greatly reduced by the flexibility and sound absorption effect of the synthetic resin, and when the plurality of bearing fittings 10 are attached to the column 3. Even if the axis of each support shaft 40 is slightly deviated, the gate 1 can be opened and closed smoothly, and the generation of abnormal noise can be suppressed.

  In addition, since the bearing bracket 10 has a structure in which the fixing position of the support arm member 14 with respect to the case member 12 can be changed, the support shafts 40 can be easily displaced even after the plurality of bearing brackets 10 are attached to the column 3. Can be fine-tuned. Further, since the streaks 42a and 48a are provided on the outer peripheral surface 42 of the support shaft 40 and the receiving surface 48 of the flange portion 46, the frictional resistance of the sliding contact surface between the bearing portion and the support shaft 40 is further reduced. Abnormal noise generated by friction is also easily diffused by the uneven structure on the surface. Therefore, the opening / closing operation of the gate 1 becomes smoother and the effect of suppressing abnormal noise is enhanced.

  Further, the shapes of the support shaft 40, the flange portion 46, and the fitting convex portion 44 are suitable for integral molding using a mold. For example, when a normal two-surface mold is used, if the mating surface of the mold is arranged along the position of the streak groove between the adjacent streak protrusions 42a and 48a, after molding, Even if some burrs are generated on the surface, there is no effect on the operation and effect of the invention described above.

  Next, a modified example of the streaky protrusion 42a formed on the outer peripheral surface 42 of the support shaft 40 will be described with reference to FIGS. Here, in the modification of FIG. 4 and FIG. 5, no streak is provided on the receiving surface 48 of the flange portion 46. In this case, when a large and heavy gate 1 is supported, consideration is given so that a new problem does not occur due to wear and deformation of the streaky projections on the receiving surface due to the load of the gate 1.

  In the modification of FIG. 4, streaky protrusions 42 b are formed on the outer peripheral surface 42 of the support shaft 40. The protrusions 42 b have a plurality of protrusions that circulate around the cylindrical side surface at regular intervals. Similarly to the streaky protrusion 42a, the streaky protrusion 42b also reduces the frictional resistance between the bearing portions of the holding members 2a and 2b and the support shaft 40, so that the opening and closing operation of the gate 1 becomes smoother. In addition, a predetermined noise suppression effect can be obtained.

  In the modification of FIG. 5, a streak 42 c formed in a spiral shape in the longitudinal direction of the columnar shape is formed on the outer peripheral surface 42 of the support shaft 40. As described above, by providing the diagonal streak 42c with respect to the rotation direction, the sliding surface can be moved more smoothly by rotation.

  Next, the modification of the structure which fixes the spindle 40 to the support arm member 14 in the bearing bracket 10 is demonstrated based on FIG. 6, FIG. In the fixing structure of FIG. 3 described above, the fitting protrusion 44 is provided at the end of the support shaft 40 on the flange portion 46 side, whereas in the modification of FIG. The convex portion 44 is omitted, and a hollow portion 50 that newly communicates from the flange portion 46 to the inside of the support shaft 40 is provided. Further, the support shaft erecting portion 34 of the support arm member 14 is omitted from the support shaft mounting recess 34a, and is newly inserted from the opening end of the hollow portion 50 on the flange portion 46 side and fitted into the hollow portion 50. A rod 52 is erected. The shaft bar 52 is preferably a hard bar made of aluminum or stainless steel, for example. Therefore, as shown in FIG. 6B, the strength of the support shaft 40 made of synthetic resin is improved by arranging the shaft rod 52 in the hollow portion 50 of the support shaft 40 made of synthetic resin.

  Further, in the modification of FIG. 7, in addition to the fixing structure of FIG. 3 described above, a hollow portion 54 that newly communicates the inside of the support shaft 40, the flange portion 46, and the fitting recess 44 is provided, and the inner peripheral surface thereof is provided. A screw groove that can be screwed with the metal fixing bolt 58 is formed. Further, the support arm member 14 has a through hole 56 formed in the bottom surface of the support shaft mounting recess 34 a so that the threaded portion of the fixing bolt 58 can be inserted. Therefore, the strength of the support shaft 40 is improved by mounting as shown in FIG. 6B and disposing the fixing bolt 58 in the hollow portion 50 of the support shaft 40 made of synthetic resin.

  In addition, the bearing metal fitting of this invention is not limited to the said embodiment and modification. For example, a structure in which the support shaft is formed integrally with the support shaft standing portion of the support arm member, and the outer peripheral surface of the support shaft and the receiving surface of the base portion thereof are formed of a synthetic resin containing carbon may be used. In addition, when it is known that the shaft misalignment when attaching to a column, such as a business bearing bracket handled by a skilled worker, is relatively small, a mechanism for finely adjusting the positional relationship between the case member and the support arm member is provided. Omitted, the case member and the support arm member may be formed integrally. Moreover, you may abbreviate | omit the streak | protrusion of the outer peripheral surface of a spindle, and the receiving surface of the root part as needed. Thus, by simplifying the structure of the main body, the manufacturing cost of the bearing fitting can be reduced.

  Furthermore, the kind of synthetic resin used for the outer peripheral surface of the support shaft and the carbon content can be changed as appropriate in view of ease of molding, mechanical strength and vibration absorption after molding,
