Abstract

The present invention relates to a fixing and fastening device comprising a clip (1) interacting with a fastening tie (2) for tightening the fastening tie (2) around at least one object. The clip (1) comprises a generally box-shaped body (3), a fastening element (4) which can generally be bent into a U-shape and which with its legs (4a, 4b) pointing into the body can be inserted into the latter, and a fastening member (5), acting between the body and the fastening element and designed to move the fastening element into and out of the body. Opposing surfaces on the fastening tie (2) and the fastening element (4) are formed with interacting, intermeshing tooth systems (4e, 2a), the fastening tie (2), when the fastening device is in use, running between one side wall (3b) of the body (3) and one leg of the fastening element (4), around at least one object and between the other wall of the body (3) and the other leg of the fastening element (4).

Description

Fixing and fastening device
The present invention relates to a fixing and fastening device according to the pre-characterising clause of claim 1.
Reference is made to GB 1 423 769, EP 0095166 Al and WO 01/88385 Al as examples of the prior art.
The object of the present invention is to provide a fixing and fastening device of the type specified in the introductory part, hereinafter called a fastening device, which has a simplified construction and functions more reliably, and in which the fastening tie can be manually pre-tensioned prior to further fastening. This is achieved in that the fastening device has the features specified in the characterising part of claim 1.
The fastening device according to the invention preferably has one or more of the features specified in the subordinate claims.
The fastening device according to the invention may be used for many different purposes, for example to tie objects such as cables and pipes together in bundles, to fasten parts such as pipe flanges together and to form a fastening for one part that is to be fixed to another, such as a child seat that is to be fixed to a bicycle frame, the body of the fastening device being permanent on the child seat.
The invention will be explained in more detail below with reference to the drawing attached, in which Fig. 1, by ay of example, shows a perspective diagrammatic view of a fastening device according to the invention. Fig. 2a shows an oblique front perspective view of a body forming part of the fastening device and Fig. 2b shows a rear plan view of the body according to Fig. 2a. Fig. 3 shows a perspective view of a fastening element and Fig.4 shows a plan view from the side of one embodiment of a fastening member acting between the body and the fastening element.
In the drawing, 1 generally denotes a clip and 2 a fastening tie interacting with the clip 1. The clip 1 comprises a body 3, see Fig. 2a, 2b, a fastening element 4 which can be inserted in the body 3, see Fig. 3, and a fastening member 5 acting between the body 3 and the fastening element 4, see Fig. 4. The fastening tie 2 is preferably made of a flexible material such as plastic, textile or sheet metal.
The body 3 is generally box-shaped and at its base 3a has slot-shaped openings 3d and 3e adjoining two opposing side walls 3b, 3c respectively. The openings 3d and 3e serve as openings for the fastening tie 2. In the centre of the base 3a of the body 3 there is a circular through-opening 3al for the fastening member 5, as -will be explained in more detail later.
The fastening element 4 is generally U-shaped with legs 4a, 4b and, as stated, is inserted in the body, the legs 4a, 4b pointing into the body bearing against the side walls 3b, 3c of the tie 2 is not inserted. It is obviously arbitrary in this context whether, for example, the leg 4a bears against the side wall 3b or 3c.
The legs 4a, 4b of the fastening element maybe articulated in relation to the section 4c of the fastening element 4 situated between the legs 4a, 4b. In order to achieve this, there is a notch 4d between each leg 4a, 4b and the section 4c, the remaining material serving as hinge joint.
In other embodiments the legs 4a and 4b are fixed in relation to the middle part 4c. The fastening element 4 is then an unresilient shoe, the size of which is designed so that the fastening tie 2 together with the fastening shoe 4 completely fills the space available in the body 3. If the fastening element 4 in this embodiment is inserted into the body 3 without the fastening tie, the legs 4a and 4b do not bear against the body walls.
On their surfaces facing the body walls 3b, 3c, the legs 4a, 4b of the fastening element 4 are formed with tooth systems 4e, designed to interact with and mesh with corresponding tooth systems 2a formed on the fastening tie 2.
In the embodiment shown in the drawing, the fastening member 5 is a screw inserted through the opening 3al in the base 3a of the body 3, the head 5a of which screw is formed so as to facilitate manual turning of the screw and which is designed with its opposite end to enter into threaded engagement with the fastening element 4. In a practical embodiment, the screw is of a common, commercially available type, the hexagonal head of which is integrally cast into the construction designed to facilitate manual turning.
The threaded engagement with the fastening device 4 may be achieved by means of a thread formed in the fastening device 4 or by means of a nut of conventional type, which is either detached or firmly fixed to the fastening device.
In order to prevent unwanted or accidental turning of the screw, the outside of the base 3a of the body 3 round the opening 3al and the surface of the screw head 5a facing the body 3 are formed with interacting patterns 6 of radial ridges 6a. The use of the fastening device can be seen from Fig. 1, in which the device is fastened to a tubular object 7. In this case the tie 2 is placed in a U-shape around the object 7, so that the tooth systems 4e of the fastening element 4 mesh with the tooth systems 2a on the fastening tie. Since the fastening tie is of a length designed to suit the largest object on which the device is likely to be used, it is now also possible to cut off the excess length of the fastening tie. The body 3 is then brought over the fastening tie 2 and the fastening element 4, so that the fastening tie 2 runs between one side wall, for example 3b, of the body 3 and one leg, for example 4a, of the fastening element 4, around the object, between the other side wall 3c of the body and the other leg 4b of the fastening element 4. Any projecting part of the fastening tie 2 can in this case be taken out through one of the slot openings 3d or 3e in the body. Sections of the fastening tie 2 situated outside the openings 3d, 3e may be used for manual stretching of the fastening tie.
The fastening member 5 is then inserted through the circular hole in the body 3 and brought into engagement with the fastening element 4 by means of the thread centrally arranged in the fastening element. For further tensioning of the tie 2, the screw head 5a is turned clockwise, in order to thereby force the fastening element 4 into the body 3, tooth systems 4c on the fastening element 4 meshing with tooth systems 2a on the fastening tie 2 taking the fastening tie 4 with them and thereby tightening the tie section placed round the object. In order to slacken it, the screw head 5 must obviously be turned anticlockwise.
In other embodiments of the device, the toothed surfaces may be replaced by surfaces having other friction-enhancing means. These maybe of the Nelcro tape type, for example, whilst in certain applications sandpaper-like surfaces affording a high degree of friction may suffice. Nor is it always necessary for the legs of the fastening element to be sprung in relation to the intermediate section thereof in the manner described above. The fastening element is then made without the notches 4d and in a way otherwise suited to the application in question. This may mean that the legs 4a and 4b constitute parts of a box-shaped fastening device, for example, not having the distinctive character of self-contained legs.
The fastening member 5 may also be formed in various ways. In order to provide the facility for a further increase in the tightening tension, the screw head 5a may be combined with a rotatable eccentric device, which acts on the top of the body 3. In conjunction with this it may also be possible to dispense with the thread on the screw 5 and the fastening device 4 and instead to couple these together by way of a bayonet fitting or similar means.
