The invention relates to a wall hook for quick assembly according to the preamble of claim 1.

In known wall hooks, which consist of an expandable dowel and a hook, the first Dowel inserted into a borehole in a wall and then the hook screwed into the dowel, uiobei the dowel spreads and jams in the Bahrloch.

Especially with small hooks, screwing in &

often a tool, bspuj. a pair of pliers, used will. If a large number of hooks have to be attached to the wall, there is also a loss of time disadvantageously noticeable by screwing in.

In the case of reinforced concrete walls, it is necessary to fasten wall hooks by means of nails due to the hardness of the reinforced concrete

uiand not possible, so that wall hooks in reinforced concrete

walls need to be pegged _o

It is the object of the invention to provide a wall hook according to the preamble of claim 1 that can be fastened quickly, safely and, if possible, without tools in a hole in a wall.

This task is carried out by the

Protection claim 1 specified features solved. \

The inventive design achieves in a particularly advantageous manner that a quick clamping of the dowel in the borehole by means of the clamping part articulated to the tie rod part causes a secure clamping of the dowel in the Bahrlach _o

It is particularly advantageous if the tie rod part has a latching section at its end facing away from the joint * This facilitates the installation of the wall hook by removing the pull anchor part from the front stop surface of the dowel axially through the dowel and the locking mechanism on the rear stop surface latched.

The insertion of the tie rod part is facilitated by what is specified in the characterizing part of claim 3 Characteristics.

A particularly quick and easy preloading of Dowels and hooks are used in the identifying part of claim 5 specified features allows.

The over-datum position of the cam section characterized in claim 6 ensures a reliable pre-tensioning, automatic opening of the clamping part being made more difficult.

The developments of claims 7 to 3 facilitate manufacture and thereby enable inexpensive mass production.

The feature specified in the characterizing part of claim 11 ensures, in a particularly advantageous manner, that due to the load on the hook, the tension of the hook does not unintentionally open, which is particularly important, when the Uiandhaken in the axial direction, for example when Use as a hook for pre-tensioning an Ulasch line, is charged.

Further advantageous developments of the invention are carried out the remaining subclaims characterized.

The invention is explained below using an example with reference to the drawing; in this shows:

- »- I O rA „ „nn ^ nn

The wall hook consists of an expandable dowel 1o
with front and rear stop surfaces 11, 12 and
a hook 2o axially penetrating the dowel.

The hook 2o has a tie rod part 21 which at one end has a latching section which tapers to a point. The latching section 2k has latching devices on its area of greatest diameter which protrudes towards the tie rod part 21, which in their latching position have a larger diameter than the axial bore of the dowel. the
Latching devices 27 can, however, be placed on the tie rod part, their outer diameter then being less than or equal to the diameter of the axial bore of the anchor, but a spring force ensures that the latching devices 27 automatically expand into their locking position.

At the end of the tie rod part facing away from the latching section Zk, the tie rod merges into a tensioning part 22, the material thickness of the hook 2o being reduced in such a way that it is in
a portion forming the hinge 23 is flexible _{or the like}
the hook continues continuously into a rigid hanger part 29, which is used for hanging pictures, for example
is suitably designed ", starting from the hanger part 29 extend laterally of the section with reduced material thickness and movable relative to this two neck sections 25, 25 '(see Fig. 3), which have an I-cam surface." This I-cam surface goes into a seat 2S

which lies on the rear side of the hanger part 29 applied by the hanger 3a.

In Fig. 2 the clamping part 22 is pivoted around the joint 23, the seat surface 26 resting against the front stop surface 11 of the dowel 1in. When the clamping part 22 is pivoted about the axis 23, the neck surface 28 slides on the front stop surface 11, the dowel 1a being axially compressed between the locking devices 27 of the locking section Zk and the neck surface 28 and thus spreading radially. This radial expansion ensures that the dowel 1a jams in the Bahrlach 3. The securing position of the clamping part shown in FIG.

The wall hook according to the invention ensures that quick assembly a secure hold. In addition, a damage-free dismantling of the then dowels suitable for reusability are possible, which is, for example, in the case of frequent renovations (exhibition stands, Window dressing, etc.) is advantageous.
