Description

Built-in handle for doors

technical field

The present invention relates to a built-in handle installed on the door of an equipment storage box, etc., and used when inserting a fingertip to open and close the door.

Background technique

An example of a built-in handle is described in Patent Document 1. The above-mentioned built-in handle includes: a raised portion raised toward the back side in a form in which a hand insertion recess is formed on the front side; and a flange portion extending around the recessed portion. Bolts are planted at four corners on the rear side of the flange. The raised portion is fitted into the mounting opening formed in the door from the front side, and bolts are passed through the bolt holes formed in the four outer corners of the mounting opening. Screw the nuts on the four bolts from the rear side of the door to secure the handle.

Patent Document 1: Japanese Patent Laid-Open No. 2002-250154

The above-mentioned conventional built-in handle adopts a structure in which four stud bolts are screwed with nuts. During manufacture, it takes a lot of trouble to plant the four bolts in fixed positions, and the cost is high. During installation, it is necessary to form four bolt insertion holes on the door and screw nuts on the four bolts respectively, so there is a troublesome difficulty in installation.

Contents of the invention

Therefore, an object of the invention according to the present application is to provide a built-in handle that can contribute to reduction of production cost with a simple structure and can be attached to a door very easily in a short time.

The raised portion 3 is fitted into an attachment opening 32 formed in the front panel 31 of the door, and the flange portion 4 is in close contact with the front surface of the front panel 31 . The embedded handle 1 includes: an engaging part 5 and a stud bolt 6 . The engaging component 5 is fixed on the outer surface of the protruding portion 3 . Stud bolts 6 are protrudingly provided on the back surface of the flange portion 4 . The engaging component 5 includes a mounting piece 5 a and a locking piece 5 b, and is fixed to the outer surface of the raised portion 3 through the mounting piece 5 a. One side edge 5c of the attachment piece 5a is arranged along the base of the flange portion 4a. The engaging piece 5 b has a support slope 5 d that stands upright from the side edge 5 c of the mounting piece 5 a and inclines in a direction gradually away from the rear surface of the flange portion 4 . Between the support slope 5 d and the back surface of the flange portion 4 is formed an outwardly expanding clamping space 7 for receiving the side edge 32 a of the mounting opening 32 . The stud bolts 6 correspond to the bolt holes 33 formed outside the side edge 32b of the mounting opening 32, and are fastened with the nuts 8 from the back side of the door.

In another built-in handle 1, instead of the above-mentioned stud bolt 6, a nut 11 is fastened to the back surface of the flange portion 4b. Bolts 12 and nuts 11 are screwed together through bolt holes 33 from the back side of the door.

According to the built-in handle of the invention according to the present application, the simple structure can contribute to the reduction of the production cost, and the efficiency of the installation work of the door-facing installation can be improved by reducing the fastening work of bolts and nuts.

Detailed ways

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

The built-in handle 1 includes a protruding portion 3 protruding toward the back side in a form in which a hand insertion recess 2 is formed on the front side, and a flange portion 4 extending around the recess 2 . As shown in FIG. 6 , an opening 32 for attachment is formed in the front panel 31 of the door. The built-in handle 1 is fixed to the front panel 31 by inserting the protruding part 3 from the front side of the door into the opening 32 for installation as shown in FIG. superior.

As shown in FIG. 6, the installation opening 32 formed on the front panel 31 of the door has a substantially rectangular shape similar to and slightly larger than the shape of the base section of the raised portion 3 of the embedded handle 1, including: The one side edge 32a and the second side edge 32b, and the third side edge 32c and the fourth side edge 32d at right angles thereto. Bolt holes 33 are formed at positions spaced outward from the middle portion of the second side edge 32b at predetermined intervals. The bolt hole 33 is an elongated hole in which the major axis is approximately twice the minor axis in the direction perpendicular to the second side edge 32b.

The protruding part 3 of the built-in handle 1 is formed by punching, and has a substantially trapezoidal box shape having first to fourth side plates 3a, 3b, 3c, 3d and a bottom plate 3e, and a hand insertion recess surrounded by the side plates and the bottom plate 2 Open towards the front side. A part 4c of the flange part 4 protrudes toward a part of the open part of the recessed part 2, and forms the protruding part for finger gripping.

An engaging member 5 is fixedly attached to the outer surface of the side plate 3 a of the raised portion. A stud bolt 6 protrudes from the rear surface of the flange portion 4b of the side plate 3b along the raised portion.

The engaging member 5 is formed by bending a rectangular iron plate into a substantially V shape, includes a mounting piece 5a and a locking piece 5b, and is welded to the outer surface of the side plate 3a of the bulge through the mounting piece 5a. One side edge 5c of the attachment piece 5a is arranged along the base of the flange portion 4a on the side plate 3a side.

The engaging piece 5b of the engaging member 5 has a supporting inclined surface 5d standing upright from the side edge 5c of the mounting piece 5a and gradually inclined away from the rear surface of the flange portion 4a. Between the support slope 5d and the back surface of the flange portion 4a is formed an outwardly expanding clamping space 7 for receiving the side edge 32a of the mounting opening 32 .

The stud bolts 6 protrude at positions corresponding to the bolt holes 33 formed outside the side edge 32 b of the mounting opening 32 . When the protruding portion 3 is fitted into the mounting opening 32 , the stud bolt 6 penetrates the bolt hole 33 and protrudes toward the back side. The nut 8 is screwed and fastened to the stud bolt 6 so as to sandwich the side edge 32b between the flange portion 4b.

In the built-in handle of another embodiment shown in FIG. 9 , nuts 11 are fastened to the back surface of the flange portion 4 b instead of the above-mentioned stud bolts 6 . When the protrusion 3 is fitted into the mounting opening 32 , the nut 11 coincides with the bolt hole 33 . The handle 1 is fixed to the front panel 31 of the door by screwing the bolt 12 into the nut 11 through the bolt hole 33 from the back side of the door.

In order to install the built-in handle 1 on the front panel 31 of the door, as shown in FIG. 32, and make it protrude toward the back side of the front panel 31. The supporting slope 5d of the engaging piece 5b can correspond to the thickness dimension of the front panel 31, and support the side edge 32a of the opening at an appropriate height position. Therefore, it is possible to cope with various types of front panels 31 having different thicknesses. Next, the side plate 3 b side of the raised portion 3 is fitted into the opening 32 while rotating the fitting handle 1 around the contact portion with the side edge 32 a of the opening, and the bolt 6 is inserted into the bolt hole 33 . When the nuts 8 are screwed to the bolts 6 protruding toward the back side of the front panel 31, the installation of the built-in handle 1 is completed.

In the built-in handle 1 of another embodiment shown in FIG. 9 , after fitting the raised portion 3 in the opening 32 as described above, the bolt 12 is screwed to the nut 11 through the bolt hole 33 from the back side of the front panel 31 . . Regardless of the embodiment, the bolts and nuts need only be tightened once, so the installation work toward the door is extremely easy.
