    CLIP FOR FASTENING AN OBJECT SUCH AS A WIRE, CABLE OR
    PIPE TO A SUBSTRATE
    TECHNICAL FIELD
    20195037 PRH 22 -01- 2019
    The invention relates to fasteners for craftsmen/electricians more particularly to a clip for securing wires, cables or pipes, which is particularly suitable for plasterboard.
    BACKGROUND
    There are a lot of different clips on the market. Usually these are a pin or nail with a holding part or head attached to it. This works well on wood and boards based on wood, while gypsum boards are 15 somewhat more difficult because the structure of the gypsum is crushed and gives less friction to forces that will pull the clip out. This has been solved by a clip which displays a larger friction surface by replacing the nail / pin with a plate.
    Another solution is described in patent NO
    306363 Bl. Here, a clip is described with two curved legs on either side of a guide pin where the two curved legs are bent apart when tapped into a plasterboard and thus require greater forces to be removed 25 from the plate. One problem with this solution is that the legs are bent back relatively easily or that the plasterboard is destroyed when the clip is removed.
    DE 102013020300 Al discloses a device having an eye with two legs extending from the eye. The legs 30 include a resilient region. The ends of the legs are formed with a friction-reinforcing geometry. The friction-enhancing geometry is a holding arm, a tooth or a lamella. The holding arm is provided with a longitudinal axis of the legs, forming an angle in a range from 35 45-70 degrees. The retaining arm comprises a frictionsupporting profile and teeth and / or lamella on the outer side, the fixing device being made of plastic and / or metal.
    SUMMARY OF THE INVENTION
    20195037 PRH 22 -01- 2019
    The invention describes a clip for attaching objects such as wires, cables or pipes to a substrate. The clip includes a holding part for holding the object firmly to the substrate, and a fastening part for fastening the clip to the substrate. The clip compris10 es right and left concave curved legs, one on each side of the holding part, each with a bending portion on the upper part of the leg against the holding part and a locking bar which is connected between the inside of the upper part of each leg at an equal dis15 tance from the holding part. The locking bar comprises a left bending portion, a left bar section, a middle bending portion, a right bar section and a right bending portion. The two bar sections are attached to the inside of the legs at the same distance from the hold20 ing part pointing down towards the middle in a Vshape, where the curvature of the two legs is such that the two partial bars lie on a straight line when the clip is hammered down in the substrate. The two legs also slope inwardly so that the lower point of 25 the two respective legs is vertically below the respective outer edges of the holding part.

    DETAILED DESCRIPTION
    20195037 PRH 22 -01- 2019
    In this description, downwards is the direc- tion from the holding part towards the legs and upwards will be opposite. The clip is often mounted on the ceiling and wall, but we will describe the clip as fastened to a horizontal substrate from the top side. 10 Right and left are seen from the front.
    The invention is a clip for attaching objects such as wires, cables or pipes to a substrate. The clip according to the invention is shown in Figure 1 and is particularly suitable for plasterboard. The 15 clip comprises a holding part 1 for holding the object firmly against the substrate, and a fastening part 2 for fastening the clip to the substrate, preferably the plasterboard.
    The holding part of the clip includes left 20 and right concave curved legs 3, 4, one on each side of the holding part 1, the clip being provided with a leg bending portion 11 on each of the upper portions of the legs adjacent the holding part. This means that the two legs can be bent outwards towards the sides 25 when the clip is hammered down in the substrate. Furthermore, the clip according to the invention is provided with a locking bar 5 which is connected between the inside of the upper part of each leg 3, 4 at an equal distance from the holding part. The locking bar 30 comprises a left bar bending portion 6, a left bar section 7, a middle bar bending portion 8, a right bar section 9 and a right bar bending portion 10 as shown in Figure 1. The two tie bars are attached to the inside of the legs at the same distance from the holding 35 part and point downward toward center in a V shape. Preferably, the curvature of the two legs is such that the two bar sections lie on a straight line when the
    20195037 PRH 22 -01- 2019 clip is completely hammered down into the substrate. In order to achieve this, the two legs must initially be inclined inwardly so that the lower point of the two respective legs is vertically below the respective 5 outer edges of the holding part. In this way it is also avoided that the substrate is damaged in an area which is not covered by the holding part and is thus visible .
    In an advantageous embodiment, the clip is 10 punched out of a metal plate.
    In one embodiment, the bending portions 6, 8, 10 and 11 are narrowed portions between bar sections and legs, between the two bar sections and between the legs and the holding part. Preferably, the narrowed 15 portions of the locking bar 5 are indents on the upper side of the bar at the bar bending portions at the legs 6, 10 and on the lower side at the bar bending portion 8 between the bar sections 7, 9. Preferably, each bar section has an abutment point 12 on the upper 20 side of the facing leg. These two abutment points abut the respective legs when the two bar sections are aligned. An abutment point is a point on an outer edge on a bar section, having the feature that it abuts against other portions of the clip when the locking 25 bar is aligned. Each bar section further has an abutment point on the lower and middle sides which abut each other when the bar sections are aligned. This configuration has the effect that the bars are aligned from their original V-shape to a straight line as the 30 clip is hammered further down into the substrate. The last part of the straightening of the locking bar 5 is effected by pressing it down towards the substrate towards the end of the downward movement. When the clip is mounted on a substrate and forces that pull the 35 clip upwards are applied, the locking bar will prevent the legs 3, 4 from being bent back. Due to the abutment points and the linear design of the locking bar
    20195037 PRH 22 -01- 2019 when the clip is hammered down, the vectors of the forces acting from the legs of the locking bar will remain in contact with the locking bar. The locking bar will also not be bent back to its original V-shape 5 because it abuts the substrate and the locking bar is further prevented from an upward directed bending by striking against the projection 13. Figure 2 shows a clip which is hammered down in a substrate.
    The abutment point is best achieved by the 10 indents at the bar bending portions 6 and 10 spanning an equally large angle a as half the complementary angle of the inner angle of the V-shape of the two locking bars. While the indents at the middle bar bending portion 8 span 2a. These targets cannot be used di15 rectly because there is a deformation of the brace bending portion. Therefore, the ideal shape should be obtained by testing with the aforementioned angles as a starting point. In addition, there is, of course, a connection between the curvature of the two legs, the 20 length of the locking bar and the angle of the Vshape. Again, best results are obtained by testing. However, it is advantageous that the curvature of the legs is larger on the inside than on the outside so that the outer side is to some extent pushed against 25 the gypsum or the substance from which the substrate consists .
    In a preferred embodiment, a weaker breaking portion 14 is provided between the holding part 1 and the fastening part 2. The purpose of the breaking por30 tion is to be able to remove the visible portions of the clip without damaging the substrate so that it must be replaced. This applies especially for plasterboard. It is natural that the breaking portion 14 and the leg bending portion 11 coincide because they are 35 made in the same manner, namely by an indent.
    In a preferred embodiment, a projection 13 is provided
    20195037 PRH 22 -01- 2019 in the middle of the lower part of the holding part which bears towards the two bar sections when they lie on a straight line, that is, when the clip is hammered down in the substrate. The purpose of the projection 5 13 is to prevent the bar sections from bending in the opposite direction when the clip is hammered down.
    In a preferred embodiment, both legs are provided with a substantially linear inclined surface 17 which forms a pointed angle with the respective outer 10 side surface of each leg as shown in Figure 1. This provides effective penetration of the surface of the substrate and helps push the legs out to each side by attachment to the substrate. This surface pushes the upper and outer surface of the legs toward the upper 15 and outer side of a cavity which the legs produce when they are hammered down into the substrate. In this way, a greater counter-force to the force that the holding part exerts on the object to be attached is achieved.
    The holding part may have different embodiments for different purposes. In one embodiment shown in Figure 3, the holding part 1 comprises a height section 15 which is attached to the fastening part 2 and is substantially parallel to the fastening part, a 25 holding section 16 which is perpendicular to the height part and a smaller lip 17 which is at a downward angle relative to the holding part. On the bend between the height section and the holding section, it is often an impact point 18 which is a horizontal sur30 face just above the attachment part to enable strokes at this point to propagate as straight down as possible. The embodiment of Figure 3 is a clip for electrical cables.
    In another embodiment, the holding member 35 comprises a fork clip formed as a fork. Other variants of the holding part are also possible, but are not part of the central part of the invention. Also it is conceivable to have one fastening part on each side of the object to be fastened and a holding part bridging the gap between the two fastening parts.
