Lower door storage

The invention "relates to a lower door mounting with a lever arranged on the door, which is directed to a in a stationary bearing body rotatably mounted axis can be put on, wotei the axis against Pulling out is secured.

In a "known version of a lower door bearing, the axis is secured by a locking ring

secured against pulling out. The axis is there in a sleeve. To also the rifle against To secure pulling out, a log is arranged on the axis, the outer diameter of which is larger is than the outer diameter of the sleeve and which is also held by the locking ring. A special tool is required for assembly and disassembly.

The object of the invention is to provide a lower door mounting to create "in which an assembly or a conversion without" special tools can be done easily and quickly can and which consists of a few parts.

To solve this problem, the invention provides that a sleeve made of elastic in the bearing body Material is introduced that holds the axis in a snap-on connection.

According to the invention, the axle is provided with a groove at its lower end and the sleeve has one The collar that snaps into the groove. The bundle is expediently at the free end of the bushing arranged and it is this end exposed, so that an outward expansion is not hindered.

• · n *

To secure the sleeve against being pulled out, it is provided with a second collar, its Outside diameter is larger than the inside diameter. knife of the opening receiving the sleeve of the bearing body.

According to the invention, a bearing body that can be welded to a door frame can be designed symmetrically in this way be that the sleeve can be inserted into the opening from "both sides, so that for one Right or left stop the same bearing is used can be.

The embodiment of the sleeve is "particularly simple, if "both collars are arranged opposite one another at the free end. Dismantling without a "special tool, in particular, easier if the rear snap-on edges are beveled.

The manufacture and assembly can be "particularly advantageous take place if the bushing is made as a molded plastic part 1st trained, the operation being particularly quiet and maintenance-free.

Further details of the invention are explained in more detail with reference to the drawing, which shows an exemplary embodiment. Show it:

Fig. 1 shows a section through a door mounting with a base plate according to the lines I - I in Figrr 2,

Fig. 2 is a plan view of this door mounting,

Flg. 3 shows a section through a weldable bearing according to the arrows III-III in FIG. 4 and FIG

Flg. 4 is a top view of this liger.

In the case of the lower door bearing according to FIGS. 1 and 2, a bearing body 2 is inserted into a bore 3 and held by a collar 4 and a caulking 5 in a base plate 1. The base plate 1 is fastened "in the floor in the appropriate position relative to the door during installation". For the rotatable mounting of a door, not shown, an axis θ rotatably mounted in a bushing If is arranged in an opening 6 of the bearing body 2, on the upper end 9 of which a lever attached to the door is usually placed. and underside of the bearing body 2 each provided with an extension 11 or 11. In the upper extension 10 supports

the box 7 with eicsa P ^ .ind 12 a "b. On this

X) CLTIuL ic ιόν SxIlΘ jjog £ X * SCii.r. JS ij CU.SZ * CLuCn Gj.I1

Axial needle bearings placed on the weight of the door is transmitted via a collar 14 on the axis 8.

At its lower end 15, the axis 8 is provided with a groove 16 in which a free end 17 consisting of an elastic material, "preferably of wear-resistant plastic, e.g. polyamide" Sleeve 7 inwardly directed collar 18 is snapped behind.

Another, external collar 19 of the sleeve 7 prevents this "when the axis 8 is mounted oten can be pulled out of the opening ό.

During assembly, the sleeve 7 is through the "breakthrough 6 pushed down through, wofcei through, the elasticity of the material of the collar 19 according to springs inside to spring up again after reaching the extension 11. For inserting the axis 8 is the lower end 15 beveled so that the protruding into the extension 11 free end 17 of Bush 7 over the collar 18 Taeimiün lead first after is pressed on the outside and then snaps into the groove 16 .

In order to facilitate the installation and removal, the rear folding edges are 20 of the collars 18 and 19 of the groove 16 and also the transitions of the opening 6 into the Extensions 10 and 11 run diagonally. If the axis 8 is pulled upwards, the in the Groove 16 snapped collar 18 also lifted the sleeve 7 until the outer collar 19, at the rear snap edge 20 of the opening 6 is applied. Pulling out the sleeve 7 and the axle 8 further is prevented by the collars 18 and 19. If, on the other hand, the sleeve 7 is held down when the axle 8 is pulled up, so the collar 18 is resilient to the outside via the lower rear snap edge 20 of the groove 16 pushed away and the axis 8 can be pulled out completely. Then the sleeve 7 is also there removable.

A cover 21 can be used in the extension 11 to accommodate lubricating grease.

In another embodiment (Figs. 3 and 4), in which a bearing body 2 is to be welded, e.g. the frame of a door that is used is to freely turn the bearing to the right or left to be able to use the door, the bearing body 2 in the loading

rich of the opening 6 formed symmetrically. The extensions 10 and 11 are thus dimensionally accurate at the same time, so that the sleeve 7 and the bolt 8 can be inserted from any side.

The advantages achieved by the invention "consist in particular that the axis is secured and despite the fact that the Leger only consists of a few parts, it can be assembled easily and quickly without any special tools. and can be dismantled and, if necessary, storage is simplified by using the same parts for the left and right stop.
