The above-mentioned conventional embedded handle has to prepare a plurality of types of products with different dimensions corresponding to a plurality of types of door panels having different thicknesses, resulting in waste of production mold, inventory space, and inventory management. ing.
Therefore, the invention according to this application provides an embedded handle for a door that can be attached very easily without a tool only by changing the cut size of the mounting hole regardless of the thickness of the door panel to be applied. It is an issue.

Hereinafter, the present invention will be described with reference numerals in the accompanying drawings, but the invention according to this application is not limited thereto.
In order to solve the above problems, in the invention according to this application, the main body 2 including the bulging plate portion 4 and the flange portion 5 that are integrally formed of synthetic resin, and the main body 2 is fixed to the door panel 31. A door embedding handle 1 is provided. The bulging plate portion 4 in the embedded handle 1 is fitted into a mounting hole 32 formed in the door panel 31 so as to protrude from the front side to the back side, and has a receiving recess 7 having an opening 6 on the front side of the door. The bulging portion 8 that holds the one side edge portion 32 a of the attachment hole 32 is formed between the rear surface of the flange portion 5. The flange portion 5 is formed to spread outward around the opening 6 of the bulging plate portion 4 so as to contact the front surface of the door panel 31. The fastener 3 is ratcheted on the bulging plate portion 4 toward the back surface of the door panel 31 so that the main body 2 is fixed to the door panel 31 by sandwiching the door panel 31 from the back surface side with the flange portion 5. Engageable to move in one direction.

  According to the invention according to this application, by fastening the fastener, it is possible to freely fix and fix the door panel with different thickness dimensions between the flange portion, regardless of the plate thickness dimension of the door panel to be applied, By simply changing the cut size of the mounting hole, it is possible to provide an embedded handle for a door that can be mounted very easily without a tool.

  Embodiments of the present invention will be described with reference to the drawings. 1 is a front view of the embedded handle, FIG. 2 is a rear view of the embedded handle, FIG. 3 is a left side view of the embedded handle, FIG. 4 is a right side view of the embedded handle, FIG. 5 is a plan view of the embedded handle, and FIG. FIG. 7 is a sectional view taken along line VI-VI in FIG. 1, and FIG. 7 is a sectional view taken along line VII-VII in FIG.

  The embedded handle 1 is attached by being fitted into a rectangular mounting hole 32 formed in the door panel 31 of the housing, and includes a main body 2 and a fastener 3 for fixing the main body 2 to the door panel 31. . The rectangular attachment hole 32 includes one side edge 32a and the other side edge 32b that face each other in parallel. The main body 2 includes a bulging plate portion 4 and a flange portion 5 that are integrally formed of synthetic resin.

  The bulging plate portion 4 is fitted into a mounting hole 32 formed in the door panel 31 so as to protrude from the front side to the back side. The bulging plate portion 4 forms a receiving recess 7 on the inner side. The receiving recess 7 has a rectangular opening 6 corresponding to the mounting hole 32 on the front side of the door. The flange portion 5 extends outward in all directions from the entire periphery of the opening 6 along the front surface of the door panel 31. Further, the bulging plate portion 4 includes a bulging portion 8 that protrudes so as to enter the back surface side of the one side edge portion 32a of the mounting hole 32, and inside the bulging portion 8 during the door opening / closing operation. A finger-holding portion 9 for hooking a finger is formed, and a holding space 10 for holding one side edge portion 32a of the attachment hole is formed on the outer side with the back surface of the one side portion 5a of the flange portion 5.

  As shown in FIGS. 6A and 6B, the sandwiching space 10 has a plurality of stepped contact steps formed outside the bulging portion 8 so that a plurality of types of door panels 31 having different thicknesses can be sandwiched. By the part 11 and the contact slope 12, the flange part 5 is gradually enlarged in the spreading direction. The space | interval of each contact step part 11 and the back surface of the flange part 5 is set so that it may respond | correspond to the thickness dimension T (FIG. 6a) of the standard multiple types of door panel 31. FIG. The contact slope 12 corresponds to an arbitrary door panel 31 having a thickness smaller than that of a standard product. Therefore, the attachment hole 32 of the door panel 31 cuts the width dimension W between the side edge parts 32a and 32b so that the thickness dimension of the panel is larger corresponding to each contact step part 11.

A ratchet tooth row 13 is integrally formed on the outside of the bulging plate portion 4. The ratchet teeth row 13 extends in a direction approaching / separating from the other side portion 5b of the flange portion 5, that is, a direction approaching / separating from the back surface of the other side edge portion 32b of the attachment hole.
The fastener 3 is made of synthetic resin and engages with the ratchet teeth row 13 of the main body 2 in a ratchet manner. That is, the fastener 3 includes a frame body 14 that is movably engaged along the guide groove 13 a of the ratchet tooth row 13, and a ratchet claw elastically supported by the frame body 12 so as to be engaged with the ratchet tooth row 13. 15 and elastic legs 16 projecting from the frame 12 in the moving direction.

  Therefore, the fastener 3 is movable in one direction toward the back surface of the other side edge portion 32b of the attachment hole, and the other side edge portion 32b of the attachment hole 32 is back to the back surface of the other side portion 5b of the flange portion. The main body 2 can be fixed to the door panel 31 by sandwiching from the side. At this time, the elastic leg 16 elastically contacts the back surface of the other side edge portion 32b of the mounting hole, thereby absorbing an error between the thickness dimension of the door panel 31 and the pitch of the ratchet teeth row 13 and fastening the fastener. 3 can securely tighten the door panel 31.

  When the embedded handle 1 is attached to the door panel 31 of the housing, the side edges 32a, 32a, The width dimension W between 32b is set, and the rectangular attachment hole 32 is formed in the door panel 31. FIG. From the front side of the door panel 31, the embedded handle 1 inserts the bulging portion 8 into the mounting hole 32 first, fits the side edge portion 32 a into the holding space 10, and connects the flange portion 5 to the front surface of the door panel 31. Adhere to. Next, the fastener 3 is moved along the ratchet teeth row 13 of the main body 2 from the back side of the door panel 31, and the elastic legs thereof are brought into contact with the side edge portions 32b of the mounting holes and tightened. This completes the mounting operation of the embedded handle 1. When the thickness dimension of the door panel 31 is smaller than the position of the first-stage contact step portion 11, the side edge portion 32 a of the attachment hole is held in the holding space 10 by contacting the contact inclined surface 12.

It is a front view of an embedded handle according to the present invention. It is a rear view of the embedded handle which concerns on this invention. It is a left view of the embedded handle which concerns on this invention. It is a right view of the embedded handle which concerns on this invention.
