Description

  The present invention relates to a door or a handle attachment device for the door, and more particularly, an attachment device capable of obtaining a strong fixed state in which a fixed portion does not rattle over a long period of time even when a rod-like grip handle is used for a sliding door About.

  As one of the handles for the door, a pair of handles are formed at corresponding positions with respect to both sides of the door. There is known a rod-like handle that is fixed in a state in which it is arranged.

  5 and 6 show a conventional bar-shaped handle and its mounting device. The pair of handles 1 and 2 are formed by providing circular mounting brackets 4 which are arcuate and bent in an L shape at both ends of a linear grip 3 having a circular shaft shape, while the mounting bracket 4 of the handle 1 is The mounting side end is provided with a screw hole that opens at the end face.

  On the other hand, the mounting bracket 4 of the other handle 2 is formed into a cylindrical portion 4a by a circular hole whose end on the mounting side opens at the end face, and screw holes 6 for screwing the fixing screws 5 are provided on both sides of the cylindrical portion 4a. It has a structure.

  The mounting device for fixing the pair of handles 1 and 2 to the door A as described above has a headed mounting bolt 7 that passes through the lower hole B provided in the door A, and the through-hole 8 of the mounting bolt 7 has an axial center. And a fixing base 9 that is fixed to the outer surface of the door A with a mounting bolt 7, and a fixing screw that is screwed into the screw hole 6 of the handle 2 from the outside and fixes the handle 2 to the fixing base 9. And 5.

  In order to fix the pair of handles 1 and 2 to the door A, the mounting bolt 7 is inserted into the fixing base 9 and the lower hole B of the door A from one outer surface, and the one handle 1 positioned on the other surface of the door A The one handle 1 and the fixed base 9 are simultaneously fixed to the door A by screwing and tightening the mounting bolts 7 into the screw holes provided in the mounting bracket 4.

  Next, the cylindrical portion 4a of the mounting bracket 4 of the other handle 2 positioned on one surface of the door A is externally fitted to the fixing base 9, and the fixing screw 5 is directed toward the fixing base 9 from the screw holes 6 on both sides. The other handle 2 is fixed to the fixed base 9 by screwing.

  As described above, in the mounting apparatus for fixing the pair of handles 1 and 2 to the door A, the mounting bracket 4 of the other handle 2 is fixed by tightening the fixing screws 5 screwed from the screw holes 6 on both sides. When the fixing screw 5 is loosened, the other handle 2 is rattled.

  Conventionally, in order to prevent rattling of the other handle 2 due to loosening of the fixing screw 5, as shown in FIG. 6, the outer diameter surface of the fixing base 9 is formed on a tapered surface 10 having a small diameter on the door A side, and the screw of the handle A part of the periphery is pressed against the tapered surface 10 at the tip surface of the fixing screw 5 screwed into the hole 6, thereby applying a radial shifting force to the screwed fixing screw 5 at the tapered surface 10. 6 to prevent the locking screw 5 from loosening.

  The handles 1 and 2 as described above are not only used by being attached to a door that opens back and forth, but also can be used as a handle for opening and closing the door A of a sliding door that is horizontally pulled as shown in FIG. It has been broken.

  By the way, when the handle 1 and 2 are attached to a door that opens back and forth, a force along the front and rear direction of the door is applied to the fixed portion of the handle 2 and the fixing base 9 by the fixing screw 5. The fixed portion by the screw 5 has a structure that is less likely to loosen against a load in the front-rear direction.

  However, when the handle 2 is used as a handle of the sliding door A that is pulled sideways, there is a distance between the handle 2 and the fixed portion of the fixed base 9 by the fixing screw 5 and the grip 3, and the handle 2 is opened and closed when the door A is opened and closed. As a result, a horizontal squeezing force is applied to the fixing portion of the fixing base 9 by the fixing screw 5, and this squeezing force acts in a direction in which the fixing screw 5 located on the pulling side of the handle 2 is separated from the tapered surface 10. When opening and closing is repeated, the fixing screw 5 to which vibration of the door A is applied is loosened, which causes a problem that the handle 2 is rattled.

  Therefore, in order to solve the above problems, the problem of the present invention is that the fixing screw is not loosened even if a lateral twisting force is applied to the fixing portion by the fixing screw of the handle and the fixing base. An object of the present invention is to provide a handle mounting device that can prevent the handle from rattling even when used for a horizontal sliding door.

  In order to solve the above-described problems, the present invention fixes the handle by fixing the cylindrical end of the handle to a fixed base protruding from the outer surface of the door and tightening a fixing screw screwed into the handle from the outside. In the handle attachment device fixed to the base, a configuration is adopted in which a concave groove having a width capable of screwing a fixing screw is provided around the fixed base.

  The fixed base is circular and has through holes for mounting bolts that are fixed to the door along the axis. The width of the recessed groove provided around the fixed base allows the fixing screw thread to be screwed in. It is possible to adopt a structure set in (1). The specific width of the concave groove is set to be narrower than the thread diameter of the screw thread of the fixed screw, and equal to or wider than the valley diameter.

  Here, the handle is formed by providing a circular shaft-shaped mounting bracket that is arcuate and bent into an L shape at both ends of a linear grip that is a circular shaft shape, while the mounting bracket of the handle has a mounting side end portion. Has a structure with a cylindrical hole formed by a circular hole opened at the end face, and a screw hole is provided at the inner end of the circular hole, and on the other hand, the mounting bracket of the handle has an inner diameter that fits externally on the fixed base, A cylindrical hole is formed by a circular hole opened at the attachment side end face, and a screw hole for screwing a fixing screw is provided at a position opposite to both sides of the cylindrical part.

  When the fixing screw is screwed in from the screw holes on both sides with the mounting bracket of the other handle fitted on the fixing base, the fixing screw enters the recessed groove of the fixing base. At this time, the screw thread of the fixing screw is recessed. By biting against both side walls of the groove and entering while tapping, the mounting bracket of the other handle and the fixing base are combined and integrated with a fixing screw, and when used for a horizontal sliding door, the pulling force in the horizontal pulling direction As a result, it is possible to prevent looseness of the handle.

  According to the present invention, in the handle mounting device in which the handle is fixed to the fixed base with the fixing screw screwed from the outside into the cylindrical end portion of the handle that is externally fitted to the fixed base, the fixing screw is attached to the outer periphery of the fixed base. Since a groove with a width that can be screwed is provided, the fixing screw thread bites against both side walls of the groove and enters while tapping, so that the handle mounting bracket and the fixing base are just double nuts. It can be combined and integrated with the same looseness-prevented condition, and even if a horizontal twisting force is applied to the fixed part of the handle and the fixed base, the fixed screw will not be loosened, and the handle can be used as a horizontal sliding door. Even if it is used, it is possible to prevent the handle from rattling.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as the past.
