Description

[Detailed description of the invention] The present invention relates to a door knob or handle mounting device, and more specifically, it is capable of easily mounting a knob or handle for a pull on a door, and also allows screws and other mounting members to be attached externally. The idea is to make the appearance beautiful without exposing it to the outside.

In the conventional door knob or handle mounting structure, a through hole is formed in the main body of the door knob or handle, and a mounting hole formed on the end surface of the main body is aligned with the through hole.
Because the main body was tightly fixed to the door by screwing the set screw that penetrated from the back side of the door into the through hole and screwing it into the mounting hole,
To install the main body, a screw hole or mounting hole is formed on the end face, and not only is it time-consuming to screw the screw into the hole, but the screw head is exposed on the back of the door, spoiling the appearance, and the screws may be damaged. The looseness causes the knob or handle body to loosen, and in particular, when a rotational force is applied to the body, the screws may loosen or the screw threads may be damaged due to excessive threading.

For this reason, for example, in Japanese Utility Model Publication No. 54-90941, a striker of the handle 33 is attached to the tapered inner end 12 of the latch 11 as a mounting device capable of rotatably mounting the mounting member. A structure of a handle formed by forcibly fitting 1 was proposed, and according to 1 Utility Model Publication No. 45-3336, bearings of mounting bodies such as knobs, handles, push buttons, etc. were used as a stop device with a radial shape on the hole edge. A shaft removal prevention device has been disclosed in which a shaft 1 made of a bushing rod or the like is held in a mounting body by a ring body a made of a spring steel plate having a through hole in which a cut is formed. Since the mounting body and the mounting body are made only of synthetic resin, or in the case of the latter only made of metal members, there are problems in terms of strength and supporting force due to elasticity after each is fitted. The situation was such that it was desired.

The present invention has been devised to eliminate the above-mentioned drawbacks of the conventional technology. An inner hole is formed in which the fitting is fitted and fixed, and a locking step is provided along the length direction of the inner surface of the fitting, and
In the inner hole, a bulge is created in the center toward the back, and at the top of the bulge is a through hole having a slightly smaller diameter than the mounting shaft of the knob or handle and with radial cuts formed on the edge of the hole,
In addition, a metal latching plate with elastic material is pushed into the mount beyond the latching step in the inner hole of the mount, and is provided in the through hole on the mounting end surface of the main body of the knob or handle. There is a door knob or handle mounting device in which the mounting shaft is forcibly fitted, and the mounting shaft protrudes from the main body of the knob or handle and the synthetic resin mounting bracket pre-installed on the door. The main body can be installed with one touch by fitting and latching a metal latching plate whose central part is curved and protruded in the pushing direction, and the mounting members such as screws are not exposed to the outside. The following embodiment will be described in detail with reference to the accompanying drawings.The mounting hole 2 is formed in advance as a bottomed hole on the mounting surface such as the surface of the door 1 without penetrating it, and in this mounting hole 2, The main body 3 is mounted by fitting and fixing a synthetic resin fitting 5 to a mounting shaft 4 protruding from the end surface.

As shown in FIG. 1, retaining protrusions 6 are formed on the outer peripheral surface of the synthetic resin fixture 5, and these protrusions 6...
Insert and fit into the inner surface of mounting hole 2,
Alternatively, it may be fixed by fitting and adhering using an adhesive.

Therefore, the connection between the fitting 5 and the mounting shaft 4 of the main body 3 is performed by the first
As shown in the figure, an inner hole 7 is formed on the inner surface of the fixture 5 made of synthetic resin and has a hooking step 8 along its length.
For example, as shown in FIG. 2, the inner latching step 8 has a through hole 10 with a plurality of radial cuts 11 on the hole edge, and the material has elasticity. A mounting fixture 5 in which the metal hanging plate 9 is made to go over the hanging step 8 in the inner hole 7 of the fixture 5 when the synthetic resin fixture 5 is integrally inserted into the mounting hole 2. It is fitted and fixed in the small hole 5a inside the main body 3.
The mounting shaft 4 is inserted into the through hole 10 of the retaining plate 9 in the fixture 5.
By forcibly fitting into the cut 11...
Divided piece 12 formed by...
is bent, and each divided piece 12... bites into the outer surface of the mounting shaft 4 to reliably prevent the mounting shaft 4 from returning or falling off.

It should be noted that the present invention is not limited to the above-described configuration, but a protrusion that engages with the retaining protrusion 6 of the fixture 5 may be formed on the inner surface of the mounting hole 2 of the door 1, and a protrusion that engages with the retaining protrusion 6 of the fixture 5 may be formed on the main body 3 of the knob or handle. If a protrusion is formed on the provided mounting shaft 4, the mounting shaft 4 and the hanging plate 9
The connection can be made even more reliable.

In the present invention, the hanging plate 9 is not integrally formed in the mounting hole 2 in advance as shown in FIG. In order to make it possible to fit the mounting shafts 4 into each other, a metal locking plate 9 having a desired shape or a predetermined through hole 10 is formed according to the set mounting hole 2 or the size of the mounting shaft 4, for example. As shown in Figures 1 and 2, a bulge is created in the center toward the back (the direction in which the mounting shaft 4 is pushed in), and at the top of this bulge is a hole with a diameter slightly smaller than that of the handle's mounting shaft 4, with a radial shape on the hole edge. A through hole 10 with a plurality of cuts 11...
A metal latching plate 9 having elasticity and material elasticity is separately fitted and fixed by passing over the latching step 8 in the fixture 5, and the above-mentioned operation connects the mounting shaft 4 to the latching plate 9. This is to firmly connect the plate 9 with the plate 9.

When the locking plate 9 is separately fitted and fixed into the fixture 5, the central part of the locking plate 9 should be moved in the direction in which the locking plate 9 is pushed in (toward the left in the figure) during fitting and installation, as shown in Figure 1. ) and a cut 11 provided on the edge of the through hole 10.
By extending any one of them to the outer edge of the locking plate, the mounting shaft can be forcibly fitted into the through hole 10 of the locking plate 9 when connected to the mounting shaft 4. When mating, the diameter of the retaining plate 9 is forcibly reduced by the pressing force so that the retaining plate 9 passes over the retaining step 8 of the inner hole 7 of the fixture 5, so that it can be fitted and fixed inside the fixture 5. It is what you do.

According to the knob or handle attachment device according to the present invention as described above, the attachment 5 made of synthetic resin or the like is attached to the door.
The main body 3 of the knob or handle is attached to the metal latching plate 9 inside.
It can be mounted with one touch by forcibly fitting the mounting shaft 4 provided on the holder, and the mount 5 is made of elastic synthetic resin, and the central part of the mount 5 is made of metal and pushed in the direction. Since the curved and protruding hanging plate 9 is pushed in, the synthetic resin body composing the fixture 5 and the hanging step 8 formed on its inner surface are made of metal with high elasticity and material elasticity. Due to the synergistic effect with the latching plate 9, the bonding force between the mounting shaft 4 and the latching plate 9 is extremely good, so the installation work is extremely simple without using tightening members such as screws as in the conventional case. Not only that, but there is no fear that the knob or handle itself will become loose due to loosening of screws, etc., and the fixture 5 is fitted into the mounting hole 2 formed in the door 1 and covered with the mounting end surface of the main body 3. Since the mounting members are not exposed to the outside, there is no need to worry about spoiling the appearance.

In addition, a retaining protrusion 6 is formed on the outer periphery of the fixture 5 made of synthetic resin to ensure that it does not fall off from the mounting hole 2 of the door 1. Inside the tool 5 is a metal locking plate 9 having an elastic material, that is, a metal locking plate 9 whose central portion is curved and protruded in the pushing direction. The latching plate 9 is provided with a through hole 10 having a slightly smaller diameter than the mounting shaft 4 of the knob or handle and having radial cuts 11 formed on the edge of the hole, and is shaped according to the purpose, and is available in a variety of sizes. The mounting shaft 4 of the fixture 5 is designed to be able to be fitted, and the latching step 8 in the inner hole 7 of the fixture 5 is passed over and the small hole 5a in the fixture 5 is fitted into the small hole 5a of the fixture 5. By forcibly fitting the mounting shaft 4 into the through hole 10 of the plate 9, the cuts 11...
Since the dividing piece 12 between them is bent and bitten into the outer peripheral surface of the mounting shaft 4 and brought into contact with it, the connection between the mounting shaft 4 and the latching plate 9 is ensured, and as a result, This makes it possible to securely attach the main body 3 of the knob or handle to the door 1.
