Technical Field

The present invention relates to a fastener for a plate-like element and a plate-like element system comprising such a fastener.

Background

In practice, it is known to bolt together two laminated sheet-like elements, in which a plurality of pairs of aligned through holes are provided. During assembly, the bolts are first inserted into all the through-holes of the first plate-like element, a distance sleeve is then placed on each bolt, the second plate-like element is then aligned with its respective through-hole with the respective bolt, the second plate-like element is lowered, the bolts are passed through the through-holes of the second plate-like element until the second plate-like element is supported on the distance sleeve, and finally a nut is screwed on the bolts to a predetermined degree of fastening. One bolt, one distance sleeve and one nut each form a bolt connection.

In such a plate-like element system, there are many pairs of aligned through holes and thus the same number of bolting means, for example possibly up to 30 or more bolting means. If any one of the bolt connections is missed, or if any one of the bolt connections is incomplete, such as when the distance sleeves are missed, cumbersome reworking is often required. The installation work itself of these bolted connections is also time-consuming and costly. In addition, the number of parts is large. Each bolted connection has at least three parts.

Disclosure of Invention

The object of the invention is therefore to provide a fastening element for connecting two or more laminated sheet-like elements in a stack and a sheet-like element system comprising such a fastening element, by means of which a reliable connection of two laminated sheet-like elements can be realized quickly and inexpensively.

To this end, the invention provides a fastener for connecting two laminated sheet-like elements, which comprises, in succession in the longitudinal direction, a first section, a second section, a third section, a fourth section and a fifth section, wherein the first section is configured to rest with its first side facing the first sheet-like element on the outside of the first sheet-like element; the second section being receivable in the through hole of the first plate-like element; in a first orientation of the fastening element relative to the first plate-like element, the third section is configured such that it can pass through the through-opening of the first plate-like element, and in a second orientation of the fastening element relative to the first plate-like element, the third section is further configured such that it rests with its first side facing the first plate-like element on the inner side of the first plate-like element, and the third section is further configured such that it rests with its second side facing the second plate-like element on the inner side of the second plate-like element; the fourth section is configured to pass through the through-hole of the first plate-like element in the first orientation and the fourth section is receivable in the through-hole of the second plate-like element; and said fifth section passes through the second plate-like element.

The third section may act as a spacer between the two sheet-like elements. Since the third section is an integral component of the fastening element, there is no longer any need to worry about the problems caused by the loss of the distance sleeve, as in the prior art. In addition, the installation of the fastener is simpler compared to prior art bolt-on devices. Here, the fastening element only has to be rotated in the circumferential direction by a predetermined angle. The omission of installation of a single fastener need not result in cumbersome rework, but rather merely the addition of the omitted fastener.

The fifth section passes through a through hole in the second plate-like element. In some embodiments of the invention, the fourth section has a height corresponding to the thickness of the second plate-like element, and the fifth section is configured such that it can pass through the through-hole of the first plate-like element and the through-hole of the second plate-like element in the first orientation and is configured such that it can rest on the outside of the second plate-like element in the second orientation, which fifth section can be used to fix the second plate-like element in place. The use of such a fifth section makes it possible to achieve the fixing of the second plate-like element in a particularly simple manner.

In a further embodiment, the fifth section may have an external thread on which a nut is screwed for fixing the second plate-like element in place. In a further embodiment, the fifth section may have a through-hole, for example a bore hole, into which a pin can be inserted for fixing the second plate-like element in place.

In some embodiments of the invention, the fastening element may further comprise a resilient claw extending from the fifth section, which resilient claw is snappable into the recess of the second plate-like element in the second orientation for forming a fixation of the fastening element in the circumferential direction. By such a resilient claw or other locking mechanism, the assembler can clearly perceive the installation end position of the fastener, and the fastener can be reliably held in the end position by the above-described locking mechanism.

In addition, the removal of the fastening element is also easy, for which purpose the snap-fit of the elastic claw with the recess is first disengaged, for example by means of a tool, and then the fastening element is turned back into the first orientation relative to the plate-like element, and can then be pulled out of the through-hole of the two-layer plate-like element without hindrance.

In some embodiments of the invention, the fastener may be integrally made of plastic, for example by injection molding. This results in a particularly inexpensive fastening element.

In some embodiments of the invention, the first section may have on its second side facing away from the first plate-like element a strip-shaped operating handle or other structure or feature that allows an assembler to easily rotate the fastener. By operating the handle, the assembler can easily install the fastener.

In some embodiments of the invention, the first section may be cylindrical and may have a diameter larger than the smallest dimension of the through hole of the first plate-like element; the second section may be cylindrical and may have a diameter equal to or smaller than the smallest dimension of the through hole of the first plate-like element; and the third and fourth sections may be cylindrical with a non-circular cross-section.

However, it is apparent that in other embodiments, any one or more of the first through fourth segments may have other shapes. For example, the first section can also be formed by a plurality of radially extending segments, rods or other discrete elements spaced apart from one another in the circumferential direction. The second section may have a non-circular cross-section. The third section may also be formed by a plurality of radially extending segments, rods or other discrete elements spaced apart from one another in the circumferential direction. The third section can also be formed in its middle portion in a retracted manner relative to its first and second sides in the longitudinal direction, in order to save on the total amount of material required for the manufacture of the fastener.

The present invention also provides a plate-like element system comprising two or more stacked plate-like elements in which pairs of through holes are provided in a stacked relationship, and a plurality of fasteners according to embodiments of the present invention, each fastener being installed in one of the pairs of through holes.

In some embodiments of the invention, the number of through holes in each plate-like element may be more than 10, in particular more than 20, in particular more than 30.

The fasteners may be of uniform shape and size.

In some embodiments of the invention, the first plate-like member and the fastener may have mating indicia for determining a first orientation of the fastener relative to the first and second plate-like members.

The invention also provides a fastener for passing through a first through hole of a first plate-like member and a second through hole of a second plate-like member to hold the first and second plate-like members together in a spaced relationship one above the other, the fastener being rotatable between a first orientation and a second orientation relative to the first plate-like member, the fastener comprising: a first section configured to abut against an outer side of the first plate-like member when the fastener passes through the first and second through holes; a third section configured to pass through the first through hole when the fastener is in the first orientation, and configured to rest on an inner side of the first plate-like element and on an inner side of the second plate-like element when the fastener is in the second orientation; and a fifth section configured to pass through the first through hole when the fastener is in the first orientation, the fifth section including a locking element that passes through and beyond the second through hole when the fastener passes through the first and second through holes.

In some embodiments of the invention, the fastener further comprises a second section between the first section and the third section, the second section being configured to be within the first through-hole when the fastener is fully inserted into the first and second through-holes.

In some embodiments of the invention, the fastener further comprises a fourth section between the third section and the fifth section, the fourth section being configured to be within the second through-hole when the fastener is fully inserted into the first and second through-holes.

In some embodiments of the invention, the fifth section comprises at least one locking element configured to pass through the first and second through holes when the fastener is in the first orientation and to abut against an outer side of the second plate-like element when the fastener is in the second orientation.

In some embodiments of the invention, the fastener further comprises a sixth section comprising at least one cantilevered resilient finger.

In some embodiments of the invention, the fastener is a one-piece plastic fastener.

The present invention will be described in more detail with reference to the following examples, which are illustrated in the accompanying drawings. The attached drawings are as follows:

FIG. 1 shows a schematic perspective view of a fastener for plate-like elements according to an embodiment of the invention;

fig. 2 shows a schematic partial view of a plate element system according to an embodiment of the invention.

Fig. 3 shows a schematic partial view of the plate element system according to fig. 2 from another viewing angle.

Detailed Description

Fig. 1 shows a schematic perspective view of a fastener for plate-like elements according to an embodiment of the invention, and fig. 2 and 3 show schematic partial views of a plate-like element system according to an embodiment of the invention, which comprises the fastener of fig. 1.

In the plate-like element systems shown in fig. 2 and 3, an upper first plate-like element 11 and a lower second plate-like element 12 are arranged at a distance one above the other. Each through hole 13 in the first plate-like element 11 may be aligned with a corresponding one of the through holes 14 in the second plate-like element 12. In the two-layer sheet-like element a number of pairs of superposed through holes 13, 14 are provided. For example the number of pairs of through holes may be up to 30 pairs or more, for example 40 pairs or more. One fastener as shown in fig. 1 may be installed in each pair of through holes. As shown in fig. 2 and 3, additional components 16 can also be provided, if necessary, in the intermediate space between the two sheet-like elements. If the component 16 is to be penetrated by a fastener, the component 16 needs to be provided with corresponding perforations.

In the embodiment shown in fig. 1, the fastener comprises, in the longitudinal direction, a first section 1, a second section 2, a third section 3 and a fourth section 4 and a fifth section 5 in that order. A bar-shaped operating handle 7 is provided on the upper side of the first section 1. Alternatively or additionally, an actuating recess or an actuating projection can also be provided on the circumferential surface of the first portion 1. A pair of resilient fingers 6 may be provided on the underside of the fifth section 5, projecting upwardly.

During installation, the fastening element is inserted in its first orientation x relative to the first and second plate- like elements 11, 12 into the through-opening 13 of the first plate-like element 11 until the lower part of the first section 1 rests with its lower side facing the first plate-like element on the outer side of the first plate-like element, at which point the second section 2 is received in the through-opening 13, the first side 8 of the third section 3 facing the upper part of the first plate-like element does not yet rest on the inner side of the first plate-like element 11, the second side 9 of the third section facing the lower part of the second plate-like element rests on the inner side of the second plate-like element 12, the fourth section 4 is received by the through-opening 14, and the first side 10 of the fifth section 5 or of the fifth section facing the second plate-like element 12 does not yet rest on the outer side of the second plate-like element 12.

Then, when the fastening element is rotated by a predetermined angle and thus reaches the second orientation y of the fastening element relative to the plate- like elements 11, 12, the third section 3 rests with its first side 8 facing upwards towards the first plate-like element 11 on the inner side of the first plate-like element 11, the third section 3 is held with its second side 9 facing downwards towards the second plate-like element 12 on the inner side of the second plate-like element 12, and the fifth section or its first side 10 rests on the outer side of the second plate-like element 12, and the spring fingers 6 snap into the associated recesses 15 of the second plate-like element 12. It may be particularly advantageous to provide a pair of mutually opposite resilient fingers 6 and a pair of matching recesses 15, although one resilient finger or more than two resilient fingers are also possible. The height dimension of the second section 2 corresponds to the thickness of the first plate-like element 11. It can be particularly advantageous to clamp the first plate-like element 11 between the first section 1 and the third section 3 in an interference fit. The height dimension of the fourth section 4 may correspond to the thickness of the second plate-like element 12. It may also be advantageous to clamp the second plate-like element 12 between the third section 3 and the fifth section 5 in an interference fit. The height dimension of the third section may determine the spacing between the two plate- like elements 11, 12.

In order to facilitate the fitter in installing the fastening elements, it is possible to provide matching markings on the outer side of the first plate-like element 11 and on the fastening elements. When the markings are aligned with each other, the fastener is in a first orientation x relative to the plate- like elements 11, 12. In the case of a fastener having a bar-shaped operating handle 7 as shown in fig. 2 and 3, the operating handle 7 itself may serve as such a mark.

The plate-shaped elements 11, 12 may be, for example, circuit boards or other self-supporting or non-flexible sheet-like elements, such as thin metal sheets, engineering plastic sheets, etc.

Finally, it is pointed out that the above-described embodiments are only intended to be understood as an example of the invention and do not limit the scope of protection of the invention. It will be apparent to those skilled in the art that modifications may be made in the foregoing embodiments without departing from the scope of the invention. The technical features described in the present application may be arbitrarily combined, and all of the combinations are technical contents described in the present application as long as the combinations are not mutually contradictory.
