Description

  The present invention relates to a mounting base with a handle.

  FIG. 12 of Patent Document 1 shows “a matter for connecting and fixing the mounting base with the handle inside and outside the wall surface on the inside and outside of the door via the fixing tool”. The problem in the design of this Patent Document 1 is that the screw head of the fixing tool can be seen from the outer surface (surface) of the mounting base with handle, for example.

  Patent Document 2 discloses an example of a mounting base with a handle as in the embodiment of the present invention. The one described in Patent Document 2 is “one end portion (door bottom side) with respect to a pivot that is attached to the wall surface of the free end portion of the door with the lock box and that supports the proximal end portion of the handle. And the other end portion (the end portion on the door end side) are connected and fixed via fixing tools, respectively. The mounting pedestal described in this Patent Document 2 has a push-pull handle pulled or pushed, and the inner and outer mounting pedestals are fixed at both the one end on the door bottom side and the other end on the door tip side. The flange portion of the mounting base does not “float” (separation phenomenon) from the edge of the door opening.

However, since the screw head of the fixing tool appears at the end portion on the door tip side as in Patent Document 1, in order to cover this screw head, for example, the end portion on the door tip side of the inner handle is attached to the inner mounting base. It is necessary to form a relief recess or notch on the outer surface of the other end of the inner handle on the door end side so that it extends to the tip surface and the inner handle can rotate about the reference axis. There is a difficulty that there is.
Japanese Patent Laid-Open No. 11-50707 JP 2006-257651 A

  In view of the problems of Patent Documents 1 and 2, the intended purpose of the present invention is that there is no need for a cover or a cover part for covering the screw head of the fixing tool inserted through the end portion on the door end side, The flange portion of the mounting base can reliably prevent “floating (separation phenomenon)” from the edge of the door opening.

  The mounting base with handle according to the present invention is mounted on the wall surface of the free end of the door with the lock box, and the one end is fixed via a fixing tool with respect to the pivot that pivotally supports the proximal end of the handle. In the mounting base with handle, the other end of the mounting base is provided with a fitting projection extending horizontally from the back surface thereof and fitted into a mounting hole formed in the wide side wall of the lock box. And Specifically, one end of each door is fixed to each other with reference to a pivot that is fitted to the inner and outer wall surfaces of the free end of the door with the lock box and pivotally supports the proximal end of the handle. In the mounting base with the handle connected and fixed through, the other end of the mounting base, extending horizontally from the back surface thereof, and the mounting holes respectively formed on the wide side walls of the lock box, respectively The inner and outer fitting protrusions to be fitted are provided.

  Here, the concept of “the wide side wall of the lock box” includes a bearing plate that is attached so as to face the wide side wall of the lock box itself, or the outer wall surface of the wide side wall of the lock box, and has a mounting hole. A shaped support plate is also included.

(A) FIG. 8 is an explanatory diagram when, for example, the operation ends 18b and 19b of the inner and outer handles 18 and 19 are pulled (pulled) toward the front side of the operator. As indicated by the arrows, when the operation ends 18b and 19b of the inner and outer handles 18 and 19 are pulled, the inner and outer handles 18 and 19 rotate by a predetermined amount about the pivot 20 as a fulcrum. At this time, by the pulling operation of the inner handle 18, the “lifting (separation phenomenon)” with respect to the edge 14 of the opening 12 at the end 16 on the door bottom side is the lock box 3 positioned behind the wall surface of the door. The contact relationship between the mounting hole 8 and the fitting protrusion 32 of the mounting base 4 with a handle on the inner side is reliably (effectively) prevented. In other words, since the inner peripheral surface of the mounting hole 8 of the lock box 3 receives a component of the handle operating force from the fitting protrusion 32 of the mounting base 4 with the handle, the inner peripheral surface of the mounting hole 8 is attached with the handle. It functions as a stopper for the fitting protrusion 32 of the base 4. The effect of preventing this “lifting (separation phenomenon)” is the same in the case of the pulling operation of the outer handle 19.
(B) FIG. 9 is an explanatory diagram when, for example, the operation ends 18b and 19b of the inner and outer handles 18 and 19 are pushed (pushed) to the other side of the operator. As indicated by the arrows, when the operation ends 18b and 19b of the inner and outer handles 18 and 19 are pushed, the inner and outer handles 18 and 19 rotate by a predetermined amount with the pivot 20 as a fulcrum, respectively. At this time, by the push operation of the inner handle 18, the “lifting (separation phenomenon)” with respect to the edge 15 of the opening 12 of the end 17 on the door end side is the lock box 3 positioned behind the wall surface of the door. The contact relationship between the mounting hole 8 and the fitting protrusion 32 of the mounting base 4 with a handle on the inner side is reliably (effectively) prevented. In other words, since the inner peripheral surface of the mounting hole 8 of the lock box 3 receives a component of the handle operating force from the fitting protrusion 32 of the mounting base 4 with the handle, the inner peripheral surface of the mounting hole 8 is attached with the handle. It functions as a stopper for the fitting protrusion 32 of the base 4. The effect of preventing this “lifting (separation phenomenon)” is the same in the case of the push operation of the outer handle 19.
(C) Since the fitting protrusion is inserted into the attachment hole formed in the lock box at the end of one of the inner and outer mounting bases 4 and 5, or the inner and outer mounting bases 4 Since the end portions on the door end side of 5 are not connected and fixed to each other via the fixing tool, the screw head of the fixing tool does not appear as described in the conventional patent document 1, and the aesthetic appearance of the design In addition to being excellent, a cover and a cover portion for covering the screw head of the fixing tool are not required as described in Patent Document 2.
(D) In the invention described in claim 3, since the mounting hole of the lock box is visible, it is very easy to mount the inner and outer mounting bases 4, 5 to the door.

FIG. 4 is a perspective view showing the lock box 3 on the inner surface side and the inner handle 18 on the outer surface side of the mounting base with handle 4 as a reference. 5 and 6 are schematic cross-sectional views based on FIG. FIG. 7 is a rear view of the mounting base 4 with a handle.

  First, with reference to FIG. 1, the mounting base 4 with a handle is formed in a rectangular shape in front view so that the outer peripheral portion (the four side edges) protrudes from the opening 12 of the door 1. . In other words, the left and right edges and the upper and lower edges of the mounting base 4 with a handle serve as a flange for the opening 12 of the door 1.

  Next, with reference to FIGS. 4 to 7, the vertical portion of one end portion (end portion on the door bottom side) 16 is the vertical portion of the other end portion (end portion on the door end side in the embodiment) 17. Are not located on the same vertical plane, and one end portion 16 falls to the back surface (inner surface) side.

  In other words, the vertical portion of the other end portion 17 is thicker than the vertical portion of the one end portion 16. A detailed description of the cross-sectional shape is omitted, but a plurality of steps are repeated from the vertical portion of the other end portion 17 to the connecting portion 25a for the fastener at one end portion (door bottom side) 16. Thus, a hollow portion 25 having a concave shape facing the front is formed.

  When the inner handle 18 is incorporated into the punched portion 25 via the bearing portion and the pivot 20, the outer surface (surface) of the handle 18 and the inverted U-shaped outer surface (surface) of the handle mounting base 4 are substantially the same. In addition, the punching portion 25 allows the handle 18 to rotate as required.

  Therefore, the innermost connecting portion 25a for the fastener that is connected to the one end portion 17 through the inclined portion is penetrated for a plurality of fasteners (stoppers) 21 at a predetermined interval in the vertical direction. A small hole 26 is provided.
