Description

[Detailed description of the invention] This invention relates to a handle for opening and closing the door of a building, which is related to a door handle.

Traditionally, many door handles have been made of metal pipes such as aluminum, brass, or iron, which allow for smooth opening and closing movements, but none of them have decorative finishings on the handles, making them tasteless. It was dry.

This idea solves these drawbacks by providing an appropriate number of constrictions on the grip of the handle body, which is made of metal pipes such as aluminum, brass, or iron, to create a smooth, uneven decoration. To provide a door handle that has an elegant appearance and has a grip part that is hard to slip and has the practical effects of making opening and closing operations easier and more reliable.

An embodiment of this invention will be described below.

1 and 2, a first embodiment is shown, and reference numeral 1 denotes a handle body formed of a metal pipe such as aluminum, brass, or iron. This handle body 1 has a first constriction 2, a second constriction 3, and a third constriction.
A constricted portion 4, a fourth constricted portion 5, and a fifth constricted portion 6 are formed, and a smooth uneven decoration process is performed. The shape of this decoration is vertically symmetrical in the length direction of the handle body 1 with the third constriction 4 as the center, and the second constriction 3 is thinner than the first constriction 2, and similarly, the fourth constriction 5 is also thinner than the fifth constricted portion 6. From the second constriction part 3 to the third constriction part 4, the shape is gradually and gently bulged, and from the fourth constriction part 5 to the third constriction part 4, the shape is similar. Attachment parts 7 are formed at both ends of the handle body 1 by curving the ends of the handle body 1, and the ends 8 are parallel to the surface of the door 9 made of wood, glass, metal, etc. A female threaded portion 10 is formed at the end portion 8.

The surface of the handle body 1 is plated and finished with lacquer coating, and may also be surface-finished by alumite treatment or the like as appropriate.

Next, to explain how to attach the handle of this invention to the door 9, as shown in FIG.
Although the door 9 is directly fixed to the door 9 with a male thread 11 that fits into a female thread 10 formed on the end 8 of the door 9, the mounting method is not limited to the illustrated mounting method.

Figures 3 to 5 show a second embodiment of this invention. The reference numeral 1 is also a handle main body, and as in the first embodiment, a first constriction 12, a second constriction 13, a third constriction 14, and a fourth constriction 15 are formed, and from the first constriction 12 The center of the surface between the second constrictions 13 is gently depressed, and the same is true between the fourth constriction 15 and the third constriction 14. . Also,
A recess 16 is provided at the end 8 of the handle body 1, and female threaded portions 17 are provided on both sides of the end 8.

As shown in FIGS. 4 and 5, the mounting method is to fit the fixture 18 into the recess in the end 8 of the handle main body 1 through the door 9, and to attach the fixing device 18 to the female threads on both sides of the end 8. The handle body 1 is fixed to the door 9 by screwing and fixing the male screw 19 to the handle 17.

FIG. 7 shows a third embodiment of this invention. The handle body 1 has a first constriction 20, a second constriction 21, a third constriction 22, a fourth constriction 23, and a fifth constriction 2 as in the first and second embodiments.
4. A sixth constriction 25 is formed. Processing is performed to gradually swell from the first constriction section 20 to the second constriction section 21 and from the sixth constriction section 25 to the fifth constriction section 24, and from the second constriction section 21 to the third constriction section 22 and the fifth constriction section 24. The bulge from the third constriction part 22 to the fourth constriction part 23 is made smaller than the above-mentioned bulge, and from the third constriction part 22 to the fourth constriction part 2
3 has a bulge 25 in the center. Similarly to the second embodiment, female threaded portions 17 are formed on both sides of the end portion 8.

Therefore, the handle body 1 is attached to the door in the same manner as in the second embodiment.

However, the decorative processing of the handle of this invention with such tangled parts 2, 3, etc. is generally carried out by a processing method called swaging, that is, after compressing a metal pipe, it is pressed into a mold and repeatedly hammered. This is done by forging it to the required finished dimensions.

As explained above, the door handle of this invention is
The handle body 1 has an appropriate number of constricted parts 2, 3, etc. arranged on the grip part to give it a smooth uneven decoration, which gives it a very elegant appearance and also makes the grip part less slippery. This is extremely useful when attached to heavy doors such as glass doors. In addition, since the processing is performed by the swaging described above, each of the constricted portions 2, 3...
The uneven decoration has a smooth shape, and the grip feels very good to the touch, so there is no risk of injury even if you grip it strongly. Furthermore, compared to conventional decorative processing of metal handles, mass production is much easier, and great effects such as being able to be provided at low cost can be expected.
