Description

  The present invention relates to a bearing fitting for rotatably attaching a gate to a column or pole that forms the gate.

  Conventionally, a gate provided on the side of a single-family house or a passage of each apartment has a structure in which a frame-shaped portion is attached to the inside of the outer frame portion. And the one side edge part of the vertical direction of the outer frame part of the gate door was attached to the gate pillar and the eaves via the gate hinge which is a bearing metal fitting. Among the hinges for gate doors, what are called pivot hinges are a main body fixed to a column, a support arm member pivotally fixed to the main body, and a cylindrical support shaft fixed to the support arm member and positioned vertically. Was provided. And the holding member which fits rotatably with respect to a spindle was attached to the gate door.

  Furthermore, as a pivot hinge capable of finely adjusting the position of the gate with respect to the column or the like, for example, there is a hinge for mounting the gate disclosed in Patent Document 1. The hinge is provided with a fixture that is attached to the gate pole. The fixture is provided with a support arm member that protrudes toward the gate and a lock member that locks the bottom of the support arm member. In addition, the support arm member is provided with a support shaft that rotatably supports the gate, and an adjustment screw that adjusts the amount of protrusion of the support arm member from the fixture, and the adjustment screw is attached to the fixture. It is fitted with a gap that can be swung.

  The gate mounting hinge can be adjusted by adjusting an adjustment screw in a direction in which the protruding amount of the support arm member with respect to the fixture, that is, the position of the gate door with respect to the gate column is brought closer or further away. Further, the support arm member can be moved to an arbitrary position of the lock member in a direction perpendicular to the longitudinal direction of the support arm member, and the position adjustment in the thickness direction of the gate can be performed with respect to the gate pillar.

In addition, in order to hold the adjustment screw to the fixture so that it can swing, the adjustment screw is inserted from the outside of the screw insertion hole, and a retaining ring is attached to the inserted screw portion to prevent axial movement. It has a structure.

  As a structure for attaching the retaining ring to the adjustment screw disclosed in the gate mounting hinge of Patent Document 1, in view of the assembly restrictions that must be attached after the adjustment screw is inserted into the screw insertion hole, For example, a structure using an E-ring is conceivable. That is, the shaft of the threaded portion is preliminarily grooved with an appropriate dimension, and the E-ring is press-fitted in a direction perpendicular to the axis to form a retaining ring. However, it is necessary to use an adjusting screw on which an E-ring groove has been formed in advance, which increases the cost compared to a normal adjusting screw. In addition, the number of parts for the E-ring is increased, and the troublesome work of attaching the E-ring after inserting the adjusting screw into the screw insertion hole is caused, which is complicated in terms of parts management and assembly work.

  There is also a structure in which a through hole perpendicular to the axial direction of the adjustment screw is formed, and a retaining pin is inserted into the through hole after the adjustment screw is inserted into the insertion hole, thereby preventing the adjustment screw from coming off. However, this structure also has a problem that, as in the case of the E-ring described above, an additional process for forming a through hole in the adjustment screw is necessary, and the cost is increased.

  This invention has been made in view of the above-mentioned problems of the prior art, is simple in structure, inexpensive, easy to assemble, has high mounting strength, and can easily adjust the position of the gate.

The slide through hole 42c has a width in a direction perpendicular to the longitudinal direction larger than the diameter of the threaded portion of the fastening bolt 30, and the support portion 42 swings in a direction perpendicular to the longitudinal direction of the fastening bolt 30. It is made possible. In addition, a contact surface 42d having a predetermined serration is formed on the bottom surface of the recess 42a that fits with the fixing member 44 in the assembled state.

  As shown in FIG. 3C, the fixing member 44 is formed with a contact surface 44a having a serration. The fixing member 44 is fitted in the concave portion 42a of the support portion 42 in the assembled state, the contact surface 44a contacts the contact surface 42d, and the respective serrations mesh with each other and do not slide. Further, a female screw hole 44b that penetrates in the thickness direction and is screwed into the fastening bolt 30 is formed in the central portion of the contact surface 44a. The female screw hole 44b is provided so as to be positioned coaxially with the side wall through hole 20a when the fixing member 44 is in the position of the recess 20b of the case portion 24.

  As shown in FIG. 3 (d), the adjustment bolt 38 includes a head 38a, a shaft portion 38b that is not threaded, a screw portion 38c, and a tip portion 38d, and further on the end portion on the head 38a side on the shaft portion 38b. The large-diameter flange 50 is provided with a small-diameter flange 52 at the end of the shaft portion 38b on the screw portion 38c side. In this embodiment, the two flanges 50 and 52 are formed by a method of forming integrally with the adjusting bolt 38.

  Here, the relationship between the shape of the adjusting bolt 38 and the shape of the back wall through hole 40 provided in the main body 16 will be described with reference to FIG. First, the distance D between the large-diameter flange 50 and the small-diameter flange 52 of the adjustment bolt 38 is set larger with a slight clearance than the thickness T of the back wall 36 of the main body 16. Further, the diameter of the large-diameter flange 50 of the adjustment bolt 38 is φ1, the diameter of the small-diameter flange 52 is φ2, the diameter of the shaft portion 38b is φ3, the diameter φa of the large-diameter hole 40a of the back wall through hole 40, and the small-diameter hole 40b. Compared with the diameter φb, a relationship of φ3 <φb <φ2 <φa <φ1 is set.

  As shown in FIG. 3E, the tightening bolt 30 is a general bolt including a head 30a, a shaft portion 30b, a screw portion 30c, and a tip portion 30d, and a ring-shaped washer 54 is inserted therethrough. And is locked to the head 30a.

  Next, a method for assembling the bearing fitting 10 will be described. First, the main body 16 of the bearing fitting 10 is fixed to the side surfaces of a pair of left and right support columns 12 that are erected on the ground. In the fixing method, the mounting portions 32 and 34 are overlapped at predetermined positions of the main body 16, bolts (not shown) are inserted into the screw through holes 32 a and 34 a, and the bolts are screwed into nuts (not shown) inside the column 12 to be fixed. At this time, the insertion port 28 of the main body 16 is arranged so as to be oriented sideways toward the other column 12.

  Next, the adjustment bolt 38 is inserted into the back wall through hole 40 of the main body 16. First, the tip 38d side of the adjustment bolt 38 is inserted from the large-diameter hole 40a side of the back wall through hole 40. Then, it passes to the screw part 38c, the small diameter flange 52, and the shaft part 38b, and the large diameter flange 50 is locked to the peripheral part of the large diameter hole 40a. Next, the adjustment bolt 38 is slid in the direction of the side wall 20 in the locked state, and is placed in the small diameter hole 40b. Then, the peripheral edge of the small-diameter hole 40b is fitted in the gap between the two flanges 50 and 52, and is supported rotatably in a state where the axial movement of the adjusting bolt 38 is prevented.

  Next, the arm member 26 to which the shaft member 48 is previously attached is held in a direction in which the shaft member 48 is erected upward with respect to the ground, and the fixing member 44 is brought into contact with the concave portion 42a of the support portion 42. The contact surface 44a is placed downward at a predetermined position on the surface 42d. And the support part 42 is inserted from the insertion port 28 side of the case part 24 of the main body 16 in the state. Thereafter, when the front end of the support portion 42 reaches the front end portion 38d of the adjustment bolt 38, the adjustment bolt 38 is rotated and screwed into the female screw 42b of the support portion 42, and the adjustment bolt 38 is further rotated to fix the fixing member 44. When the arm member 26 has moved to a position within the range of the recess 20b of the case portion 24, the rotation of the adjustment bolt 38 is stopped.

  Next, the fastening bolt 30 into which the washer 54 is inserted is inserted from the side wall through hole 22 a on the ground side of the case portion 24. When the distal end portion 30d of the fastening bolt 30 passes through the slide through hole 42c of the support portion 42 and reaches the contact surface 44a of the fixing member 44, it is screwed into the female screw hole 44b. Eventually, the tip 30d passes through the female screw hole 44b and further advances into the side wall through hole 20a of the case side wall 20. When the fixing member 44 is moved until the support portion 42 is clamped between the fixing member 44 and the side wall 22 on the ground side, the tightening of the tightening bolt 30 is stopped. Note that, for later adjustment, a temporarily fixed state is set at this time.

  Next, as shown in FIG. 6, a support member 56 fixed to the gate door 14 is rotatably attached to a portion of the shaft member 48 protruding from the arm member 26. When adjusting the posture and position of the gate 14 with respect to the column 12, the fastening bolt 30 is loosened to release the engagement between the contact surface 44a of the fixing member 44 and the contact surface 42d of the support portion 42. The arm member 26 is screwed into the adjustment bolt 38 and is supported on the peripheral portion of the back wall through hole 38 via the two flanges 50 and 52 of the adjustment bolt 38. Here, since the two flanges 50 and 52 and the peripheral portion of the back wall through hole 38 are loosely fitted with a clearance, the arm member 26 is placed in the case portion 24 in the horizontal direction around the fitting portion. It is supported so that it can swing. Therefore, within the swingable range, the position of the shaft member 48 in the horizontal direction and perpendicular to the surface of the gate 14 can be adjusted. Furthermore, if the tightening of the adjustment bolt 38 is adjusted, the insertion position of the arm member 26 into the case portion 24 can be changed, and the position adjustment in the direction parallel to the surface of the gate door 14 can be performed. Then, when the fastening bolt 30 is tightened again when the arm member 26 reaches a desired position, the arm member 26 is fixed at that position.

  The internal state of the bearing fitting 10 in the assembled state is shown in FIG. The adjustment bolt 38 has a threaded portion 38c having a sufficient length as long as it does not interfere with the tightening bolt 30. Moreover, it is preferable that the front-end | tip part 30d is settled in the upper side wall through-hole 20a, or has passed the clamping bolt 30. FIG. Then, even if the tightening is loosened and the arm member 26 is swung during adjustment after temporary fixing, the tip 30d of the tightening bolt 30 is supported in the side wall through hole 20a. Re-tightening can be easily performed without tilting.

  According to the bearing fitting 10 of this embodiment, the gap between the large-diameter flange 50 and the small-diameter flange 52 provided on the adjustment bolt 38 is rotatably fitted to the peripheral edge portion of the small-diameter hole 40b of the saddle hole-like back wall through hole 40. Since the structure to be combined is provided, the bearing fitting 10 can be easily assembled. Further, if the large-diameter flange 50 and the small-diameter flange 52 are formed integrally with the adjusting bolt 38, the number of parts during assembly can be reduced, and the cost of the adjusting bolt 38 itself is hardly increased.

  In addition, after the bearing fitting 10 is attached to the column 12, the position of the gate 14 can be adjusted by a simple operation method. That is, by adjusting the adjustment bolt 38, the protruding amount of the arm member 26 with respect to the main body 16 can be changed, and the position of the gate 14 with respect to the column 12 can be adjusted in the direction of approaching or moving away. Further, the arm member 26 can swing the engagement portion between the adjustment bolt 38 and the peripheral portion of the back wall through hole 38 as a shaft, and the shaft member 46 can be moved in a direction perpendicular to the protruding direction of the arm member 28. The position of the gate 14 in the thickness direction can be adjusted with respect to the column 12.

  In addition, the bearing metal fitting of this invention is not limited to this embodiment, The shape of each member, a raw material, etc. can be changed suitably. For example, the shapes of the two flanges provided on the adjustment bolt, the thickness of the back wall, and the shapes of the large-diameter hole and the small-diameter hole of the back-wall through hole can be freely changed within a range that satisfies the above-described relative size relationship. What is necessary is just to set suitably according to the shape, weight, etc. of the gate attached to a support | pillar.

  Also, when the column is installed with relatively high accuracy and there is no need to adjust the position of the gate with respect to the thickness direction of the gate from the column, the configuration of the tightening bolts and fixing members that contribute to the adjustment of the direction is omitted. Also good.
