RU2310051C2 - Knob for door leaf - Google Patents

Abstract

FIELD: ironmongery, particularly handles for door leaf or similar member.

SUBSTANCE: knob has canopy and knob bearing installed in canopy and having support part. The bearing includes inner and outer rings arranged so that outer ring is installed in canopy. Inner ring includes minor upper and major lower ring members provided with facets formed in ring member ends facing each other. The facets define race for rolling element of the bearing. Support part of the bearing is made as lid arranged on door leaf surface and rotation limiter connected to knob.

EFFECT: improved service characteristics and reliability, elimination of gaps in the knob, provision of smooth and quiet knob movement, enhanced appearance, increased accuracy of knob member location and service life, possibility to take radial and axial loads.

Description

The invention relates to the field of hardware and relates to a handle for sash doors, windows or other similar element.

Known handle for the sash according to the patent of Russia No.2002931, 1993, the handle of which is mounted on a standard bearing. However, such a design does not allow for any adjustments to the handle mechanism and the bearing is not connected in any way with the other elements of the handle. In addition, this bearing is not designed for axial loads.

The closest analogue of the claimed invention is a handle for a sash containing a socket mounted on the surface of the sash, a handle bearing mounted in the socket, and a bearing portion of the bearing. The bearing has a shoulder for interaction with the outlet and is kinematically connected with other elements of the handle mechanism. This bearing accepts both radial and axial loads. However, the implementation of the bearing in the form of a single ring of plastic cannot provide high strength properties to the handle. Moreover, such a bearing has increased wear and, accordingly, during operation, the handle will manifest play.

The objective of the proposed invention is to eliminate the above disadvantages, as well as providing the ability to adjust the position of individual elements of the handle mechanism.

This technical problem is solved in that the handle for the sash contains a socket mounted on the surface of the sash and the handle bearing mounted in the socket. The bearing is made of outer and inner rings, is installed in the socket by an outer ring, and one of the rings is made of upper and lower ring elements having chamfers on one end facing one another, forming a track for the bearing rolling element in the connection.

The bearing part of the bearing is made in the form of a cover located on the surface of the sash and a rotation limiter located on the handle.

The handle may have an outer cover with a spherical surface.

The invention is illustrated by drawings, which depict on:

figure 1 - pen in isometry;

figure 2 - General view of the handle, complete;

figure 3 - the outer ring of the bearing;

4 is a smaller upper inner annular element of the bearing;

5 is a larger lower inner annular element of the bearing;

6 is a socket;

Fig.7 - cover located on the surface of the sash;

Fig - limiter rotation of the handle;

Fig.9 - the outer cover.

The handle for the sash contains a socket 1 mounted on the surface of the sash, a bearing 2 and a handle 3. The bearing 2 is installed in the socket 1 and rests on it with its shoulder made on the outer ring. The handle also includes a lower bearing support portion. Bearing 2 is made of outer 4 and inner rings. The bearing is installed in the socket with an outer ring. The inner ring of the bearing consists of inner smaller upper 5 and larger lower 6 ring elements. It is also possible to perform the outer ring of the ring elements with the entire inner ring. Ring elements can be the same size. As can be seen from figures 4 and 5, these ring elements have chamfers 6 facing one another, forming a track for the rolling element 7 of the bearing. The bearing support part is made in the form of a cover 8 located on the surface of the sash (see Fig. 2 and 7), and a rotation limiter 9 located on the handle (see Fig. 8). Between the cover 8 and the rotation limiter 9 is a torsion spring 10 associated with the handle.

The handle may have an outer cover 11 with a spherical surface, blocking access to the elements of the handle mechanism. The handle works in the usual mode for these mechanisms. The proposed handle has high performance in operation, reliable, has no backlash and ensures smooth and noiseless operation of the handle. The proposed design of the bearing provides accurate linking of the handle elements in place due to the possibility of fitting and durability in work, because perceives both radial and axial loads.
