DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a screw fastener.
Fastening means of this type are required for the mounting of curved handles provided with hollow ends on a contact face on a door, a window, a drawer or the like, fixing being achieved by means of expanding parts which are secured relative to one another in a hole by means of a screw. It is known to use curved handles in this way, for example on house doors; normal ironmongery is generally mounted on the interior of the door. If curved handles are fastened on one side from the exterior, coverings are generally required on the interior of the door, for example a blind round anchor plate or covering cap, to make the otherwise visible screw fastener as unnoticeable as possible. When arranged on a tubular frame, it is important neither significantly to influence its strength nor to create cold bridges.
An important aim of the invention is to simplify and accelerate the fastening of curved handles on wooden or tubular frame doors. Anchorage should take place quickly and reliably without covering elements being required on the interior of the door. It should also be possible to provide an axially rigid rotatable connection to a door handle without problems.
The main features of the invention are given in the claim.
According to one feature of the invention, a screw fastener of the type mentioned at the outset has a guide member for the screw comprising, for resting on the contact face, a base flange which is provided with or is connectable to the expanding parts or securing member and on which the associated hollow end is supported via a supporting member rigidly or detachably connected thereto.
A mounting set of this type consists of few components which are inexpensive to produce and can be arranged exactly in a short space of time. It is important for the guide member to take over the support on the contact face by the base flange so the curved handle does not come directly on to the contact face or allow pressing or pulling which is otherwise possible. Rather, anchorage is effected via the base flange on the contact face behind or beneath which the expanding parts are secured by the screw which passes through the guide member. The supporting member is preferably held detachably thereon and, in turn, is preferably welded to the curved handle end in order to absorb the forces and moments occurring during use of the handle as well as possible.
According to another feature of the invention, a collar of the supporting member positively overlaps the base flange of the guide member, fixing being particularly secure. According to an aspect of the invention, the supporting member can be a tube having a collar with a peripheral shoulder and an orifice which is axially opposed thereto and through which the fastening screw can be adjusted if necessary.
According to still another feature of the invention, a head is integrally connected to the base flange on the supporting body side, the head being provided with an external thread for holding a cap nut which can be overlapped positively and/or non-positively by the supporting member according to still another aspect of the invention. However, the invention also proposes that the head and cap nut be designed integrally so as to simplify production and storage.
In the design according to yet another feature of the invention, the guide member has an orifice which axially guides the screw and of which the end can be screwed into an expanding part. The screw head is preferably received in a recess provided on the head and/or on the cap nut on the supporting body side according to yet another aspect of the invention.
It is advantageous if, according to another feature of the invention, the head and/or the cap nut has, at an axial distance from the base flange, a peripheral notch, in particular a V-shaped groove in which a setscrew penetrating the hollow end and the supporting member, in particular radially, engages to fix the hollow end. This allows rapid release of the connection, if necessary, for example to exchange or adju
