JP 2002-250154 A

Each of the conventional embedded handles has a structure in which a bolt and a nut are screwed together, and there is a problem that it takes time to mount.
Therefore, an object of the present invention is to provide an embedded handle that can be attached to a door very easily and in a short time.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
The embedded handle 1 according to this application for solving the above-described problem includes a bulging portion 5 that bulges to the back side so as to form a manual insertion concave portion 4 on the front side, and a flange portion that extends around the concave portion 4. 6 and a mounting member 3 for fixing the main body 2 to the front plate 31 of the door. The handle body 2 includes first and second engaging recesses 5f and 5g between the back surface of the flange portion 6 and the bulging portion 5. The first engaging recess 5f receives the engaging protrusion 32e of the mounting opening 32 formed on the front plate 31 of the door. The second engagement recess 5g is located on the opposite side of the first engagement recess 5f with the bulging portion 5 interposed therebetween. The second engaging recess 5g has an inclined surface 5h that gradually spreads outward as it goes to the back side. The attachment member 3 includes a base 7 and a fastening member 8. The base 7 is mounted so as to be in close contact with the back surface of the front plate 31 along the side edge 32 b of the mounting opening 32. The fastening member 8 is pivotally attached to the back side of the base, and is rotatable in parallel with the back side of the base 7 between a fastening position and a release position. The base 7 has an engagement piece 7b standing on the front side along the side edge 32b of the opening 32 at one side edge 7e. The fastening member 8 includes a pressing portion 8a and a rotation operation portion 8b. The pressing portion 8a enters the engaging recess 5g of the handle main body 2 at the tightening position, engages with the inclined surface 5h and pulls the handle main body 2 to the back side, and thereby presses the flange portion 6 against the front plate 31. . The rotation operation unit 8b stands on the back side so that the fastening member 8 can be rotated and operated with a finger.

  According to the embedded handle of the invention according to this application, it is possible to mount the door to the door very easily and in a short time without screwing the bolt and nut.

It is a side view of an attachment member.

Embodiments of the present invention will be described with reference to the drawings.
The embedded handle 1 includes a handle body 2 and an attachment member 3. The handle body 2 includes a bulging portion 5 that bulges to the back side so as to form a manual insertion concave portion 4 on the front side, and a flange portion 6 that spreads around the concave portion 4. The handle body 2 has a bulging portion 5 fitted from the front side of the door into the mounting opening 32 formed on the front plate 31 of the door, and the flange portion 6 is brought into close contact with the front surface of the front plate. Fixed to the front plate 31.

  A mounting opening 32 formed in the front plate 31 of the door is substantially rectangular and has first and second side edges 32a and 32b facing each other, and third and fourth side edges 32c and 32d perpendicular to these. And an engaging protrusion 32e protruding from the first side edge 32a toward the second side edge side 32b.

  The bulging portion 5 of the handle body 2 is formed by pressing integrally with the flange portion 6, and is a substantially rectangular box shape having first to fourth side plates 5a, 5b, 5c, 5d and a bottom plate 5e, and is opposed to each other. The 1st engagement recessed part 5f and the 2nd engagement recessed part 5g are provided between the back surface of the flange part 6 of the 1 and 2nd side plates 5a and 5b. The first engaging recess 5 f receives the engaging protrusion 32 e of the mounting opening 32. The second engaging recess 5g includes a slope 5h that gradually spreads outward as it goes to the back side. Further, a finger-hanging projection 4a that bulges into the manual insertion recess 4 is formed on the front side of the engagement recess 5f, 5g. In the illustrated embodiment, the first engagement recess 5f and the second engagement recess 5g are formed in the same shape symmetrically with respect to the center line of the bulging portion 5, but are not symmetrical or the same shape. May be.

  The attachment member 3 includes a base 7 and a fastening member 8, and is attached so as to be in close contact with the back surface of the front plate 32 along the second side edge 32 b of the attachment opening 32.

  The base 7 includes a flat plate-like main body 7a having a U-shape and an engagement piece 7b standing from the one side edge 7e to the front side along the second side edge 32b of the opening. The base body 7a further includes a pair of opposed extending pieces 7c, 7d along the outer side surfaces of the side plates 5c, 5d of the bulging portion of the handle body 2. The base body 7a has the side edge 7e along the side edge 32b of the mounting opening 32 and the extended pieces 7c and 7d along the outer side surfaces of the side plates 5c and 5d of the bulging portion protruding from the opening 32 to the back side. Is attached to the back of the front plate 31.

  The fastening member 8 is pivotally attached to the base 7 with a pin 9 and is rotatable between a fastening position (solid line in FIG. 7) and a release position (virtual line in FIG. 7) in parallel with the back surface of the base 7. The tightening member 8 includes a pressing portion 8a that enters the engaging recess 5g of the handle main body at the tightening position, and a rotation operation portion 8b that stands on the back side so that it can be rotated with a finger. When the pressing portion 8a enters the engaging recess 5g of the handle main body, the pressing portion 8a engages with the inclined surface 5h and pulls the handle main body 2 to the back side, thereby pressing the flange portion 6 against the front plate 31. In the illustrated embodiment, a pair of tightening members 8 are provided, and are rotated by a predetermined angle in opposite directions so as to bring the rotation operation portions 8b closer to each other from the release position indicated by phantom lines in FIG. It is set to be the tightening position indicated by.

  If the pressing portion 8a is pressed against the inclined surface 5h with a sufficiently large spring force in a state where the tightening member 8 is engaged with the inclined surface 5h, there is no need to separately provide a means for fixing the tightening member 8 at the tightening position. . In order to reinforce the spring force, as shown in FIG. 9, the vicinity of the pivotal support portion of the fastening member 8 in the base 7 of the mounting member 3 is curved so as to be lifted from the back surface of the front plate 31, and the fastening member 8 is inclined to the slope 5h. The curved portion can be configured to be pressed against the back surface of the front plate 31 when pressed.

  If a separate fixing means is required, it can be fixed at the tightening position by binding it through a binding band 8c formed in the rotation operation portion 8b through a binding band.

  In order to mount the embedded handle 1 on the front plate 31 of the door, the bulging portion 5 is opened from the side plate 5a side to the opening 32 so that the engagement protrusion 32e of the opening 32 is fitted into the engagement recess 5f of the handle body 2. And is projected to the back side of the front plate 31. Next, from the back side of the front plate 31, the engaging piece 7b of the base 7 is hung on the side edge 32b of the opening 32, and the extending pieces 7c and 7d are placed along the side plates 5c and 5d of the bulging portion, so that the attachment member 3 Wear. When the fastening member 8 is rotated to the fastening position and fixed with a binding band or the like as necessary, the mounting of the embedded handle 1 is completed.
