Description

The invention relates to the manufacture of hardware, namely, fasteners when installing handles and can be used for fastening door and window handles made of wood, metals, polymeric materials.

Known door handle (author, witness USSR No. 1557304, IPC 7 E 05 B 1/00, publ. 15.04.90), containing a stud with threaded ends, mounted on the threaded ends of the stud outer and inner handles, an inner plate with a hole, an outer cover with a shaped hole and means for fixing the outer handle from turning relative to the door, including spikes made on the outer cover and a shaped element connected to the outer handle. In order to increase manufacturability and improve operating conditions, the shaped element is made in the form of an insert in the door handle, and shaped recesses corresponding to the shape of the insert are made in the ends of the outer and inner handles facing the plates. The presence of spikes on the inner plate fixes it relative to the door, preventing it from turning during installation.

The disadvantage of the door handle is that the handle mount loosens over time, as there is no reliable locking.

A known connecting device with countersunk heads (USSR patent No. 329709, IPC 3 F 16 B 29/00, publ. 1972), in which, in order to increase the locking reliability, the threaded end of the screw in the nut location area is made with longitudinal notches, and the nut with the sides of its end face are countersinked to the part of its height, in which the deformable sleeve is installed under pressure from the outside, the latter fills the notches. The proposed connection provides reliable locking.

The disadvantage of this connection is the difficulty of its use in the fixtures of the door handles with simultaneous butt connection (connection of the right and left handles).

The closest technical solution is a door handle from a bar (PO No. 48622, MKPO 08-06, publ. April 16, 2001), which has a fastener made in the form of two washers, two gaskets, studs with right and left threads at opposite ends. On the hairpin is made by stamping a thickening,

which repeats the shape of a groove made on a nearby washer, with a side hole for tightening the lever when installing the door handle.

The disadvantage of mounting is that over time, the handle loosens.

The problem solved by the present invention is the development of a reliable fastening for door handles.

The problem is solved by means of a fastener for door handles, which includes a stud with right and left threads at opposite ends, two washers, one of which has a central hole, the other a groove that repeats the shape of the thickening on the stud and the hole on the side surface for tightening with a lever when simultaneous butt joint of the right and left handles. The mount further comprises two bushings for screwing into the ends of the door handles, one of the bushings having an external right-hand thread and an internal left-hand thread, and the other sleeve has an external right-hand thread and an internal right-hand thread.

If necessary, one or both bushings have an additional polyethylene ring, which can be installed by any known method.

It is preferable to use a sleeve with an external right-hand thread and an internal right-hand thread with a rolled polyethylene ring.

For door handles having an additional at least one cylindrical support, a similar fastening is used.

Door handles are preferably made of polyvinyl chloride pipes with the same molding radius in two mutually perpendicular planes with the same diameter along the entire length.

The washers are preferably in the form of radius cylinders.

In Fig.1 shows a General view of the fastening, Fig.2 is a sleeve with a female right-hand thread and sealed with a polyethylene ring, Fig.3 is a diagram of the fastening of the door handle to the door, Fig.4 is a rear view of the door handles on two supports and additional third cylindrical support (on three supports)., figure 5 is a General view of an additional third cylindrical support in assembled form.

The fastener for door handles 1 contains (Fig. 1) a threaded rod 2, washers 3, 4. The washer 3 has a central hole 5, and the washer 4 has a groove 6. The fastener for door handles 1 contains a sleeve 7 with an external right-hand thread and an internal left-hand thread , sleeve 8, with external right-hand thread and internal right-hand thread. The sleeve 8 has a sealed polyethylene ring 9. On the washer 4 there is a hole 10 for tightening with a lever while simultaneously butt-jointing the right and left handles

1. On the pin 2 there is a thickening 11, located closer to the washer 4 with a groove 6, repeating the shape of the thickening 11.

The door handle may additionally contain at least one cylindrical support 12 with an opening 13 for connecting the support 12 to the handle 1 using a radius nut 14, a bolt 15 and a washer - 65 G (Grover) 16 (Fig. 5).

Figure 4 shows a General view of the door handles on two and three supports.

Door handles are obtained by molding preheated blanks from polyvinyl chloride pipes in a molding device.

An additional cylindrical support 12 is made of metal (figure 5) and is installed at the same or any other distance from the other two supports of the door handle (attachment points). An additional cylindrical support 12 is attached to the door handle 1 mechanically. In the door handle 1, holes are made for connection with an additional cylindrical support 12. The bolt 15 located in the support 12 passes through a washer 65 G (grover) 16 through the hole 13 in the support 12 into the hole of the door handle 1 and is screwed into the radial nut 14, located in the cavity of the door handle 1. Next, an sleeve 7 or 8 is screwed into the end face of the additional cylindrical support 12.

Installation of door handles using the proposed fastening is carried out in the following way:

- measure the center distance of the door handle 1;

- drill holes with a diameter of 9 mm from the street and 13 mm from the side of the room (figure 3);

- insert the pin 2 in the door so that the thickening 11 on the pin 2 is from the side of the room;

- from the side of the street put on a stud 2 a washer 3 with a hole in the center 5;

- substitute the handle 1, into the ends of which the bushings 7, 8 are screwed;

- screw the pin until the distance from the door surface to the end of the pin 2 becomes 42 mm;

- on the protruding studs 2 put on the washers 4 with a groove 6 in the center;

- put the door handle 1 to the studs 2 and with the help of the lever produce complete retraction of the handles;

- the side holes 10 in the washers 4 are sealed with a self-adhesive film, selected according to the color of the washer.

When installing handles with additional cylindrical supports, fastening is carried out similarly as described above.

The proposed mount additionally contains bushings for screwing into the ends of the door handles and cylindrical supports, which significantly increases the reliability of the mount.

The proposed fastening has enhanced locking properties due to the use of bushings with rolled plastic rings in them, which contributes to the durable connection of the sleeve with the material of the door handles when installing them on the door.
