BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an attachment element for securing elongate objects to constructional components and including a holding part securable to a constructional component, and a connection part adjoining the holding part outside of a projection plane of the connection part and extending perpendicular to a plane of the holding part, intersecting same along its end side along which the connection part adjoins the holding part, with the holding and connection parts forming a one-piece member.
2. Description of the Prior Art
Known, clip-like attachment elements are used for securing elongate objects such as, e.g., electrical conductors, water hoses and the like to constructional components.
These attachment elements have each a plate-shaped holding part securable to a constructional component, e.g., with nails or screws. The connection part, which is connected with the holding part, serves for releasably connecting an elongate object with the constructional component. German Publication DE 1775414 discloses an attachment element having a holding part and an attachment part. The plate-shaped holding part has a plurality of bores for securing the holding part to a constructional component. The connection part lies outside of a projection plane of the connection part and which extends perpendicular to a plane of the holding part, intersecting same along its end side along which the connection part adjoins the holding part. The connection part has essentially a shape of a hook.
The advantage of the known attachment element consists in that the arrangement of the connection part relative to the holding part permits to attach an object to a constructional component without any difficulty by simply attaching the holding part to the constructional component. This is because the connection part does not prevent access to the bore in the holding part or does not make the access completely impossible.
However, a drawback of the known attachment element consists in that the object cannot be secured in any arbitrary mounting position by the connection part, as the object first has to be inserted into the hook-shaped connection part.
Accordingly, an object of the present invention is to provide an attachment element that can be economically produced and, at the same time, provides for a simply attachment of an object.
SUMMARY OF THE INVENTION
This and other objects of the present invention, which will become apparent hereinafter, are achieved by providing a connection part having a bottom and two resilient clamping legs projecting from the bottom for receiving the object. The two resilient clamping legs insure an easy insertion of an object. Further, the two resilient clamping legs insure a substantially arbitrary alignment of the receiving space formed by the two legs. This insures an easy handling of the attachment element.
Advantageously, the bottom of the connection part is aligned with the holding part, which insures a stable structure of the attachment element.
The clamping legs advantageously extend substantially perpendicular to the holding part, which permits to effect the attachment process in one step. Thereby, it is possible, simultaneously, to secure the attachment element to the constructional component, on one side, and to insert an object between the clamping legs, on the other side. Further, the arrangement of the clamping legs insures a manual insertion of the object therebetween.
Advantageously, each clamping leg has a substantially M-shaped cross-section, which insures an optimal retention of an object. However, dependent on the outer profile of an attachable object, the clamping legs can have another cross-sectional shape corresponding to the profile of the object.
For manufacturing the attachment element, advantageously, a sheet blank is subjected to stamping and bending processes. These processes provide for a time-saving and simple and, thereby, economical manufacturing of the attachment element.
Advantageously, for forming the attachment elements, T-shaped or L-shaped sheet blanks are used, which insures formation of the attachment element by a very easy bending process. This again contributes to an economical production of the attachment elements.
When the attachment element is formed of a T-shaped sheet blank, the bending step includes bending-off of opposite free ends of the T-shaped sheet blank in order to form the clamping legs. By forming the clamping legs by bending off opposite free ends of a T-shaped sheet blank, a substantial economy of material is achieved.
When the attachment element is formed of an L-shaped sheet blank, there is formed in a free end of the L-shaped sheet blank, a slot extending from a free end surface of the free end up to a sheet section corresponding to the holding part, and bending off of sections located on opposite sides of the slot from a remaining portion of the sheet blank is effected to form the two clamping legs.
When the L-shaped sheet blank is used for forming the attachment element, both sheet sections, which correspond to holding and connection part, respectively, have a shape of a rectangle. This insures a material—saving manufacturing of the attachment element.
The novel features of the present invention, which are considered as characteristic for the invention, are set forth in the appended claims. The invention itself, however, both as to its construction and its mode of operation, together with additional advantages and objects thereof, will be best understood from the following detailed description of preferred embodiments, when read with reference to the accompanying drawings.
