Title: Anchoring assembly, nut holder, combination of an anchoring assembly and a structural element, method of mounting an anchoring assembly in a thin-walled structural element
The present invention relates to an anchoring assembly adapted for pre-assembling in an elongate through hole in a wall of a thin-walled structural element, the elongate through hole having a length and a width which is smaller than the length, said assembly comprising an anchoring nut.
Such an assembly is used to pre-assemble a nut in a structural element having the elongate through hole in its wall. This pre-assembling of the nut allows for standard fasteners, e.g. hexagon screws, bolts, socket head cap screws, to be mounted to the nut and hence the structural element. The structural element may be a thin-walled hollow profile or rail, preferably made of metal. The elongate through hole may be a rectangular hole with straight transverse end edges at its head ends, i.e. at the short sides of the hole, but may also be a slotted hole, which has circular end edges.
Itis an object of the invention to provide an alternative assembly of the type as mentioned at the outset.
This object is achieved by an anchoring assembly adapted to be pre-assembled in an elongate through hole in a wall of a structural element, said anchoring assembly comprising: - an anchoring nut having a top side, a bottom side and a bore with a central axis that extends from the top side to the bottom side and that defines an axial direction, the nut furthermore having lateral sides that extend from the top side to the bottom side, - two support tabs, associated with the nut and located on opposite lateral sides of the nut, the support tabs being spaced apart from the top side of the nut seen in the axial direction of the nut, the support tabs being adapted to rest in a mounted position on an outer wall portion of the structural element adjacent the elongate hole, whilst the nut is sunk in the elongate hole, wherein the support tabs have a different width.
The assembly according to the invention allows for convenient mounting of the assembly in a an elongate through hole in a wall of a structural element, in particular for convenient mounting from an outer side of the structural element.
In use, the assembly according to the invention is mounted in the hole in the wall of the structural element, e.g. a hollow thin-walled structural element such as a profile or a rail.
The anchoring assembly has a first axis that extends between the two support tabs, and a second axis perpendicular thereto. The elongate through hole in the structural element has a longitudinal axis and a transverse axis perpendicular thereto. The elongate through hole has a length in the direction of the longitudinal axis and a width in the direction of the transverse axis, wherein the width is smaller than the length.
Mounting the assembly according to the invention is done by first manipulating the assembly such that the tab having the smaller width is directed towards the elongate hole and the assembly is rotated about the first axis, and possibly tilted over the second axis, such that the anchoring nut fits through the opening.
Then, the tab having the smaller width and the nut can be inserted through the elongate hole, such that the tab having the smaller width and the nut are located within the structural element, and the gripped tab is held on an outer side thereof.
The assembly is then rotated about its first axis, such that the second axis of the assembly is substantially aligned with the transverse axis of the elongate hole. In this position it is advantageous if the wider tab, preferably has a width larger than that of the elongate hole.
Thereby it is or could be supported on the sides, i.e. long sides, of the elongate hole. Thus, the assembly cannot fall through the hole into the structural element. Then, while the nut is located in the structural element, the assembly is tilted about its second axis so as to raise the tab having the smaller width through the elongate hole to the outer side of the structural element, whilst the nut remains located within the structural element.
Subsequently, the assembly can be slid along the longitudinal axis of the elongate hole to a mounted position wherein the tab with the smaller width is moved beyond an edge at a head end of the elongate hole such that both support tabs are in supporting engagement with the outer surface of the wall of the structural element. Thus the support tabs can rest against a flat outer surface of the structural element, e.g. the hollow profile, whilst the nut is sunk into the elongate hole. Moreover, the assembly prevents that the nut or parts to be assembled thereto can fall into the hollow profile.
Additionally the assembly according to the invention allows for mounting a nut in the elongate hole in the thin-walled hollow structural element, wherein the nut has a length and/or a width that exceed the width of the elongate hole.
In an embodiment, the support tabs are part of a nut holder which comprises a nut holding portion for receiving and holding the nut.
In a further embodiment, the support tabs are attached directly to the anchoring nut, preferably by welding, more preferably by spot welding. This provides a sturdy and simple anchoring assembly. Alternatively, an assembly is envisaged wherein the two support tabs are part of a nut holder which comprises a nut holding portion for receiving and holding the nut, wherein the holding partion is attached directly to the anchoring nut, preferably by welding, more preferably by spot welding.
In an embodiment, the nut holder is formed in one piece. This provides a simple nut holder and is advantageous for manufacturing purposes, e.g. allows for fewer components and assembling thereof in the manufacturing process.
In a further embodiment, the one or both of the support tabs extend from the holding portion.
In a practical embodiment, the holding portion has a bottom plate and side walls extending therefrom, preferably, substantially perpendicular to the bottom plate, wherein the bottom plate supports the nut on its bottom side, and wherein the side walls extend along the lateral sides of the nut. Such an embodiment of the holding portion provides a sturdy base for the nut to be held in.
In a further embodiment, one or both of the tabs extend from the side walls.
In a practical embodiment, one or both of the tabs extend from the side walls at a substantially right angle and/or an obtuse angle, preferably between 90 and 120 degrees, with respect to the side walls. These angles for the tabs facilitate that the tabs can efficaciously rest against a flat outer surface of the structural element, e.g. the hollow profile, whilst the holding portion holding the nut is sunk into the elongate hole. These angles, and especially an obtuse angle for the wider tab, further facilitate efficient manipulation of the assembly during the mounting thereof in the elongate hole, as it aids in conveniently rotating the assembly whilst gripping the wider tab.
In yet another embodiment, the holding portion has a nut facing side, on which it has one or more notches and/or protrusions engaging the nut. This aids in securing the nut in its position within the holding portion, and prevents e.g. sliding movements of the nut. The one or more notches and/or protrusions in the holding portion may be provided in the bottom plate, preferably in one or more corner regions thereof. The latter further aids in preventing the nut from sliding off the edge of the holding portion.
In embodiments, the nut has one or more notches and/or protrusions, preferably teethed grooves, wherein the notches and/or protrusions of the nut are in engagement with the notches and/or protrusions of the holding portion. This leads to improved retention of the nut in the holding portion, and prevents e.g. sliding movements of the nut.
In a further embodiment, the holding portion has one or more holding lugs protruding inwardly at a level similar to or higher than the upper side of the nut. The upper side here relates to the side of the nut facing the support tabs. The holding lugs provide a limit, e.g. an upper limit, for the nut and as such can prevent movement thereof. This leads to secure retention of the nut in the holding portion.
In an embodiment, the holding portion has a pair of holding lugs on either side of the holding portion.
In a practical embodiment, the nut holder is made by bending from sheet metal, preferably of stainless steel.
In another embodiment, the nut holder is made from plastic, preferably by injection moulding.
In embodiments, the nut is an oblong nut. Alternatively, the nut is a hexagonal nut, a rectangular nut, or a round nut. It is noted that further nut shapes are conceivable, as long as they have one dimension that exceeds the width of the elongate hole.
The invention further relates to a nut holder for an assembly according to the invention.
The invention further relates to a combination of an anchoring assembly according to the invention and a structural element, e.g. a thin-walled hollow structural element, having an elongate through hole, wherein the elongate through hole has a length and a width which is smaller than the length, wherein one of the support tabs has a smaller width than the width of the elongate hole, and the other tab has a width larger than the width of the elongate hole.
The smaller tab having a width smaller than that of the elongate hole facilitates easy insertion and mounting of the anchoring assembly. The wider tab having a width larger than that of the elongate hole means that in the in the mounted position — or in any position in which the second axis of the assembly is substantially aligned with the transverse axis of the elongate hole - this wider tab can rest on the sides, i.e. long sides, of the elongate hole. As such the assembly cannot fall through the hole into the structural element.
In an embodiment, wherein the holding portion has one or more holding lugs protruding inwardly at a level similar to or higher than the top side of the nut: - the one or more holding lugs are located on the holding portion such that in the mounted position the holding lugs are located within a perimeter of the elongate through hole, and/or - in the mounted position the one or more holding lugs engage one or more edges of the elongate through hole so as to block movement of the holding portion.
In a further embodiment, the holding portion has a pair of holding lugs on either side of the holding portion, wherein: - the one or more holding lugs are located on the holding portion such that in the mounted position the holding lugs are located within a perimeter of the elongate through hole, and/or - in the mounted position the one or more holding lugs engage one or more edges of the elongate through hole so as to block movement of the holding portion.
The invention further relates to a method for mounting an assembly in an elongate through hole in a thin-walled hollow structural element, the elongate through hole having a length and a width which is smaller than the length, wherein the elongate through hole has a longitudinal axis and a transverse axis, and wherein the assembly has a first axis extending between the two support tabs and a second axis extending transverse to the longitudinal axis, wherein the support tab having the larger width is adapted to be gripped, e.g. between two fingers, the method comprising the steps of: - gripping the tab having the larger width, and whilst gripping said tab, manipulating the assembly such that the first axis of the assembly is substantially perpendicular to the hole and the second axis of the assembly is substantially aligned with the longitudinal axis of the hole, - inserting the tab having the smaller width and the holding portion with the nut through the elongate hole, such that the tab having the smaller width and the holding portion are located within the structural element, and the gripped tab is held on an outer side thereof, - rotating the assembly about its first axis, such that the second axis of the assembly is substantially aligned with the transverse axis of the elongate hole, and then tilting the assembly about its second axis so as to raise the tab having the smaller width through the elongate hole to the outer side of the structural element, whilst the holding portion with the nut remains located within the structural element, - sliding the assembly along the longitudinal axis of the elongate hole to a mounted position wherein the tab with the smaller width is moved beyond a head end edge of the elongate hole such that both support tabs are in supporting engagement with the outer surface of the wall of the structural element.
In embodiments, inserting the nut, or the holding portion with the nut, through the elongate hole is performed substantially perpendicularly to the elongate hole.
In embodiments, inserting the nut, or the holding portion with the nut, through the elongate hole is performed obliquely, i.e. tilted about the second axis of the assembly, to the elongate hole. This may e.g. be advantageous for an embodiment where a height of the assembly is larger than the width of the elongate hole.
The invention further relates to a method of manufacturing an assembly according to the invention.
The invention will be explained further with reference to the drawings, in which like reference symbols designate like parts. In these drawings:

Fig. 7 shows a view in perspective of the assembly of Fig. 5 in a rotated insertion state in the structural element, and
Fig. 8 shows a view in perspective of the assembly of Fig. 5 in a mounted position in the structural element.
Fig. 1 shows a nut holder 1 for an assembly adapted for pre-assembling in an elongate through hole in a wall of a structural element. This nut holder 1 may be made by bending from sheet metal, e.g. stainless steel. Alternatively, the nut holder 1 can be made from plastic, e.g. by injection moulding.
The support tab 3 and the support tab 4 are part of the nut holder 1 which comprises a nut holding portion 2 for receiving and holding a nut. The support tabs 3, 4 are located on opposite sides of the holding portion 2. The holding portion 2 is on another level spaced apart from the support tabs 3, 4.
The support tabs 3, 4 have a different width. The support tab 3 in Fig. 1 has a width WL which is larger than the width Ws of the other support tab 4.
The nut holder 1 is formed in one piece. The holding portion 2 has a bottom plate 5 and side walls 6 , 7 extending therefrom. In this embodiment the side walls 6, 7 extend substantially perpendicular from the bottom plate 5. The tabs 3, 4 extend from the side walls 6, 7 via an intermediate portion 11, 12 at an upper part of the respective side walls 6, 7. The intermediate portion 11, 12 is bent such that the tabs 3, 4, extend at an angle with respect to the side walls 6, 7.. The upper parts of the side walls have a width that is smaller than the width of the elongate hole.
It can be seen in Fig. 6B that the support tab 3 extends from the side wall 7 at an obtuse angle a, wherein angle a is e.g. between 90 and 120 degrees. The support tab 4 extends from the side wall 6 at a substantially right angle B with respect to the side wall.
In a possible embodiment the support tabs 3, 4 are at the same distance from the bottom plate 5, such that they define a common plane. The bottom plate 5 and the common plane of the tabs 3, 4 are in such an embodiment parallel to each other. The angles a and B are then both 90 degrees.
The holding portion 2 comprises notches 9 in corner regions of the bottom plate 5 for retaining the nut. The notches protrude into the nut facing side of the bottom plate 5.
In Fig. 1 it is shown that the bottom plate 5 comprises an opening 10. This opening 10 may e.g. be of a similar or larger diameter as - and be in alignment with — a bore in the nut. This is for example shown in the assembly 100 of Fig 2. There the diameter of opening 10 exceeds that of an inner diameter of the bore 150 in the nut. This would allow for a fastener (e.g. a threaded rod or a threaded bolt) to be threaded through the nut and pass through the opening 10 so as to install said fastener at a desired length.
The nut holder 1 has holding lugs 8 protruding inwardly. These lugs 8 are provided at a level similar to or higher than the upper side of the nut, in case the nut is held in the holding portion 2 (not shown in Fig.1). The nut holder 1 has a pair of holding lugs 8 on either side of the holding portion 2 formed on the intermediate portions 11, 12.
As shown in Fig. 2 the nut may have one or more notches and/or protrusions such as grooves 130. These grooves 130 are in Fig. 2 in engagement with the notches 9 of the holding portion 2. This type of oblong nuts is known as such, and is used commonly in combination with mounting rails, also known in the art as “strut rail”, having a longitudinal mounting slot flanked by inwardly bended flanges,
In Fig. 3 is shown a simple anchoring assembly 300 adapted to be pre-assembled in an elongate through hole in a wall of a structural element, said anchoring assembly comprising: - an anchoring nut 110 having a top side 140, a bottom side 145 and a bore 150 with a central axis that extends from the top side 140 to the bottom side 145 and that defines an axial direction, the nut 110 furthermore having lateral sides, e.g. 120, 121, 122, 123 referred to in Fig. 3, that extend from the top side 140 to the bottom side 145, - two support tabs 3, 4, associated with the nut 110 and located on opposite lateral sides 120, 121 of the nut, the support tabs 3, 4 being spaced apart from the top side of the nut seen in the axial direction of the nut, the support tabs 3, 4 being adapted to rest in a mounted position on an outer wall portion of the structural element adjacent the elongate hole, whilst the nut 110 is sunk in the elongate hole, wherein the support tabs 3, 4 have a different width.
The nut 110 is in Fig. 3 an oblong nut. The support tabs 3, 4 are attached directly to the anchoring nut 110 by means of attachment portions 311, 312, preferably by welding, more preferably by spot welding
In Figs. 3 and 4, the support tabs 3,4 extend from attachment portions 311, 312. The elements 350, 360 may be made by bending from sheet metal, e.g. stainless steel.
Alternatively, the elements 350, 360 can be made from plastic, e.g. by injection moulding, in which case the attachment portions 311, 312 may be attached to the nut 110 by an adhesive instead of welding.
The attachment portions 311, 312 along a length thereof partially engage the nut 110. The tabs 3, 4 extend from the attachment portions 311, 312 via an intermediate portion 313, 314 at an upper part of the attachment portions 311, 312. Here the intermediate portions 313, 314 are not in engagement with the nut 110. The intermediate portions 313, 314 are bent at an upper part thereof such that the tabs 3, 4, extend at an angle with respect to the attachment portions 311, 312. It should be noted that holding lugs may be arranged on the attachment portions 311, 312, e.g. on the intermediate portions 313, 314, for blocking rotation of the assembly when mounted to the structural element, which will be described further below.
In Fig. 4 is shown an anchoring assembly 400 adapted for pre-assembling in an elongate through hole in a wall of a structural element, said assembly 400 comprising a nut 450. The nut 450 is in Fig. 4 a hexagonal nut having uniformly distributed sides 451 and a bore 452.
The support tabs 3, 4 are attached directly to the anchoring nut 450 by means of attachment portions 311, 312, preferably by welding, more preferably by spot welding. Alternatively, in case the support tabs 3, 4 are made of plastic, they may be adhered to the nut, instead of welded.
In Fig. 5 is shown a view in perspective of an assembly 100 comprising the nut holder 1 holding the nut 110. The assembly 100 is in Fig. 5 in a pre-mounting state, with the smaller tab directed towards the elongate hole 210 in the wall of the structural element 200.
The anchoring assembly 100 is adapted to be pre-assembled in an elongate through hole 210 in a wall of a structural element 200, said anchoring assembly 100 comprising: - an anchoring nut 110 having a top side 140, a bottom side 145 and a bore 150 with a central axis that extends from the top side 140 to the bottom side 145 and that defines an axial direction, the nut 110 furthermore having lateral sides, e.g. 120, 121, 122, that extend from the top side 140 to the bottom side 145,
- two support tabs 3, 4, associated with the nut 110 and located on opposite lateral sides 120, 121 of the nut, the support tabs 3, 4 being spaced apart from the top side of the nut seen in the axial direction of the nut, the support tabs 3, 4 being adapted to rest on an outer wall portion of the structural element adjacent the elongate hole, whilst the nut 110 is sunk in the elongate hole, wherein the support tabs 3, 4 have a different width.
The support tab 3 and the support tab 4 are part of a nut holder 1 which comprises a nut holding portion 2 for receiving and holding the nut 110.
In Fig. 5 the support tab 4 has a smaller width Ws (shown in Fig. 1) which is smaller than the width of the elongate hole 210, and the support tab 3 has a width WL {shown in Fig. 1) which is larger than the width of the elongate hole 210.
The nut in Fig. 5 is an oblong nut. It is noted that other nut shapes are conceivable, e.g. hexagonal (cf. Fig. 4).
It can be seen that the first and a second support tab 3, 4 are located spaced apart from a top side of the nut 210 being held in the holding portion 2, by a distance d that is similar to or larger than the thickness t of the wall of the structural element 200, (i.e. see the edges 211, 212 in Fig. 5) such that in the mounted position (shown in Fig. 8) the tabs 3, 4 rest on an outer surface of wall of the structural element 200 and the holding portion 2 is sunk into the hole 210.
The elongate through hole has a longitudinal axis La and a transverse axis Tu. The assembly 100 has a first axis La extending between the support tabs 3, 4 and a second axis Ta extending transverse to the longitudinal axis La in the common plane of the support tabs 3, 4.
The support tab having the larger width, i.e. support tab 3 is adapted to be gripped, e.g. between two fingers. In this pre-mounting state the assembly 100 is yet to be mounted in the elongate hole 210 and is located on an outer side of the thin-walled structural element 200 (see Fig. 5).
In a first step the mounting involves gripping the tab having the larger width, i.e. support tab 3.
Whilst gripping said tab, the assembly 100 is to be manipulated such that the first axis La of the assembly 100 is substantially perpendicular to the hole 210 and the second axis Ta of the assembly 100 is substantially aligned with the longitudinal axis Lu of the hole 210. This is the position shown in Fig. 5.
Then, the tab having the smaller width, i.e. support tab 4, can be inserted, as well as the holding portion 2 with the nut 110 through the elongate hole 210, such that the tab 4 and the holding portion 2 are located within the structural element 200, and the gripped tab 3 is held on an outer side thereof. This is the inserted state as shown in Fig. 6A and Fig 6B.
Inserting the holding portion 2 through the elongate hole 210 may be performed substantially perpendicularly to the elongate hole 210, or may be performed obliquely, i.e. in a tilted orientation about the second axis Ta of the assembly, to the elongate hole 210.
Subsequently, the assembly 100 can be rotated about its first axis La, such that the second axis Ta of the assembly 100 is substantially aligned with the transverse axis Tn of the elongate hole 210. This is shown in the rotated insertion state of Fig. 7, wherein the assembly has rotated about its first axis La by a quarter-turn.
Then, the assembly 100 can be rotated about its second axis Ta so as to pull the tab having the smaller width, i.e. tab 4, through the elongate hole 210 to the outer side of the structural element 200, whilst the holding portion 2 with the nut 110 remains located within the structural element 200.
To achieve the mounted position, the assembly 100 can be slid along the longitudinal axis La of the elongate hole 210 to a mounted position wherein the tab with the smaller width, i.e. tab 4, is moved beyond an edge at a head end 213 of the elongate hole such that both support tabs 3, 4 are in supporting engagement with the outer surface of the wall of the structural element 200.
It can be seen in Fig. 8 that the holding lugs 8 are located on the holding portion 2 such that in this mounted position the holding lugs 8 are located within a perimeter of the elongate through hole 210. The holding lugs 8 may engage one or more edges (e.g. 211, 212 as shown in Fig. 5) of the elongate through hole 210 so as to block movement, e.g. lateral movement, of the holding portion 2.
