Definitions
- the present invention refers to a fastening device in the form of a plug, preferably made of plastic material, having a central, longitudinal hole for cooperation with a fastening element in the form of a screw or equivalent and intended to be arranged in a pre-drilled hole in building components of practically all types from board covered stud walls, light concrete walls, hollow brick walls or brick walls to casted concrete walls
- plug comprises, in its fixed condition, an inner end portion in the penetrating hole of which a thread is arranged or measures have been taken in order to facilitate thread cutting, four legs extending from the inner end portion and an outer end portion in which the legs join and which comprises a stop flange or equivalent for bearing on the edge of the hole.
- the legs use to be provided with bending notches in combination with a slight deviation of the legs.
- the deviation is achieved by means of the fact that the common sectional form of the legs, the number of which due to manufacturing reasons is limited to two, at the middle portion of the plug, forms an ellipse which in the direction of the end portions transforms into a circle.
- Such a plug comprising two legs with a middle portion having an elliptical section is known from the European Patent EP-A-0169335.
- the object of the present invention is to provide a universally usable fastening device in the form of a plug by means of which it is possible to achieve with all types of supports values for the withdrawal resistance corresponding values attainable by means of fastening devices especially designed for each type of support.
- a further object is to provide a plug which by means of its design makes it possible to be produced by injection moulding in an injection tool of the same relatively simple design, with regard to the number of moving parts, which plugs comprising only two legs allow.
- figure 1 shows a plug in a side view
- figure 2 shows the same plug rotated 90° around its longitudinal axis in a side view and partly sectioned
- figure 3 shows a section A-A through the center portion of the plug
- figure 4 shows a plug arranged in a sectioned board
- figure 5 shows the plug according to figure 4 seen from the back of the board
- figure 6 shows a plug arranged in a sectioned, solid building component.
- the fastening device comprises a plug 1 of preferably plastic material, which is provided with an axially arranged hole 2 adapted for cooperation with a screw 3.
- the plug 1 comprises, in its fixed condition, an inner end portion 4 in which the through hole 2 is provided with an inner thread or, as shown in figures 2 and 3, internal ridges 5 in which the screw at the introduction in the plug cuts threads.
- the four legs are created by means of two slots 13,14 arranged in essentially parallel planes having an increasing width in the direction of the central part of the plug.
- the central portions of the legs 6-9 are somewhat divergent and the plug has its largest part in the transverse direction at this central part. Due to the fact that the inner surfaces of the legs 6-9 are limited by the circular hole 2 and thus are straight in axial direction, the legs have also their largest thickness at the center part.
- Figure 3 which shows a section A-A through the plug, also shows that the design of the outer profile of the legs is such that if the legs are pressed to bear on each other for example by the introduction of the plug in a dead end hole 15, having nominal diameter, in a building component 16, as shown in figure 6, then the center part will have essentially the same diameter as the end portions.
- the legs 6-9 are bent or broken radially outwards which is facilitated on one hand by the fact that the legs are somewhat divergent and on the other hand by the fact that the legs are provided with sectional weakenings in the form of notches 19-22 arranged at the center parts of the legs.
- the notches 20, 22 on the legs 6-8 outside the parallel planes of the slots, turned in the direction of the center hole while the notches 19, 21 on the legs between the planes of the slots 7, 9 are turned in the direction from the center hole.
- the bending of the legs 6, 8 is further facilitated by the arrangement of sectional weakenings 23 at the ends of the slots.
