DE2116489B2 - Door plate type handle fixture - has lugs between ribs on elastic holding ring fitting gaps between counter-ribs - Google Patents

Abstract

A retaining ring, supported on a radially aligned inside socket ledge, secures the plate-mounted neck against axial withdrawal, on the handle fixture on an escutcheon, or similar plate. The ring fits in an annular socket groove, and has inward ribs engaging counter-ribs for bayonet-locking retention. The ring (16) is made of elastic material. It is supported on the ledge (13) in the bearing socket (6) by convex protuberances (18) following window-type cutouts (19) in the ring walling. It has protrusions (17) between its ribs (10), each locking into the gap (a) between two counter-ribs (8). Stability in each direction of handle turning is enhanced, and neck and plate are mounted with no possibility of axial play.

Description

The invention relates to a handle attachment to a sign, in particular a door sign, according to the preamble of single claim.

Such a handle attachment is known from GB-PS 9 67 210, in which the retaining ring is two inwardly r & gende, diametrically opposite ribs formed, which when inserted Handle neck also diametrically opposite engage behind provided counter ribs of the same. The retaining ring of this solution is not automatic after the Assembled secured. A shoulder of the located at the level of the stop surface also supports its holder Door sign. In addition, the handle neck is not an effective support in every rotational position given.

By the DE-Gm 19 97221, however, is one non-rotatable connection of handle neck and retaining ring is known in another type of handle attachment. However, this configuration lacks sufficient storage length for the handle neck.

Furthermore, the latching of a bayonet catch of a lock cylinder on a mortise lock is known a spring-loaded double-armed lever mounted in its cylinder housing (DE-PS 5 37 278). This works together with a ratchet-like projection of an expanding Bayonet slot of the mortise lock. If the locking cylinder is turned into its functional Brought into position, a wedge-shaped locking lug of the lever engages behind the ratchet-like projection of the bayonet slot in question.

The object of the invention is based on the problem of a handle attachment of the presupposed To develop the genus so that without increasing the overall height and without reducing the storage length a greater stability with regard to axially directed tensile forces, which remains constant in every rotational position of the handle and an axially clearance-free mounting of the handle neck and door plate is achieved.

This task is accomplished by the characteristics of the

characterizing part of the single claim solved

The protection relating to the overall combination of the solution features of the claim is characterized are characterized by an increased use value. The convex, the window-shaped recesses associated elevations lead to an axially play-free seat of the handle, the window-shaped Openings eliminate deformations in the case of larger axially directed tensile forces, caused by the ίο An alternative for any displaced material In addition, in contrast to GB-PS 9 67 210 a bayonet lock connection without corresponding free spaces. The other with the previously known usual bayonet connection remaining free spaces are now largely due to the projections closed. Although the retaining ring is made of elastic material, what the favorable effect regarding brings the increases, the load capacity is given in the circumferential direction, because the retaining ring μ also between the ribs, as a result of which the projections practically has the full cross section achieves that, regardless of the position or the range of rotation of the handle, a more effective support compared to the prior art is made possible.

An exemplary embodiment is shown in the drawing. It shows

F i g. 2 in the development a section of the retaining ring, which is raised against the inner shoulder the bearing bush occurs,

3 shows a view in the direction of arrow III in FIG. 1, but with parts twisted to one another in the inserted position and

FIG. 4 shows a representation corresponding to FIG. 3, wherein the retaining ring is brought into bayonet lock-like bondage

1 with a handle assigned to a shield 2 is designated, the restraint of which by means of a retaining ring 16 takes place

The bearing bore 4, which is composed of stepped bore sections 4 'and 4 " extends in a bearing bush 6.

The handle 1 occurs with its handle neck 7 in the Bearing bush 6 and has a square opening Γ for

a pusher mandrel, not shown, is step-shaped

deposited and stored with the larger cross-section

in the bore section 4 'of the bearing bush 6.

The free, cross-sectionally smaller end of the handle neck 7 has three arranged in the same circumferential distribution Opposite ribs 8, which leave column 9 between them. At the end, the mating ribs 8 are beveled in a roof shape The column 9 is used to pass the inwardly projecting, correspondingly in an even circumferential distribution arranged ribs 10 of a retaining ring 16 to achieve a bayonet lock-like Bondage between the handle neck 7 and the retaining ring 16, compare the unfettered position in Figure 3 and through Angular rotation of hertwig-led bondage position in Fig. 4th

The retaining ring 16 lies in the bore section 4 ″ of the bearing bush 6 and carries with its outer surface 11 for the storage of the handle 1, so that the total height of the shield corresponds to the storage length.

For the purpose of facilitating the assembly of the retaining ring 16, entrainment

openings 15 for a corresponding tool intended.

To secure the bayonet lock-like bondage of the retaining ring 16 are used projections 17 extending from the retaining ring 16 of the same material borrowed the material is plastic with elastic properties. The aforementioned protrusions 17 are shaped so that after reaching the bayonet lock-like bondage the projections 17 snap into the column 9 of the handle neck 7, ία so that the retaining ring 16 has practically the full cross section even between the ribs 10, compare in particular F i g, 3,

To an axially play-free mounting of the handle neck 7 and door plate 2 wear in the area of the ribs 10 on the End face 12 of the retaining ring 16 provided, convex elevations 18, which are located on the radially directed inner shoulder 13 of the bearing bush 6.

So that no deformations occur in the case of axial tensile loads in the direction of the arrow χ , the elevations 18 are window-shaped recesses 19 in the retaining ring wall. The elevations 18 can accordingly yield resiliently.
