[0001] The present registration claims the priority advantages of the priority registration submitted on January 9, 2019 with the title "Apparatus for a Capture Fastener Assembly with Expanding Grommet" (facility for a recorded fortification arrangement with exposing spout), which is hereby fully absorbed by reference. BACKGROUND
[0002] The present revelation concerns fortifications. In particular, a recorded fastening element is revealed, which contains a spout with several expanding noses.
[0003] In the field of manufacturing technology, fastening elements are used to assemble components. Fastening elements often penetrate a thin component with a prefabricated opening to absorb a fastening element. After installation, some fastening elements have an abrasive effect with the component, causing increased voltage and deformation near the opening. This can be detrimental to some components where the structure is required to prevent vibrations, crack formation, mechanical decoupling, or even for desirable aesthetics.
[0004] One solution consists in the provision of a spout and a socket, such as the in Fig. 1 spout shown from the H-type and socket. The highlighted spout of the status of the technology is typically made from a rubber material and manually inserted into an opening in a plate, so that a waist section of it sits in the opening. Accordingly, the spout and socket of the state of technology are recorded as separate components that require separate installation steps. The difficulties associated with the use of these components can arise because the components are small and are therefore slightly lost and / or damaged. Furthermore, inserting the spout of the state of the art can be tedious into an opening and / or require significant introductory workers and / or skill. These challenges can cause damaged components, too much manual work and / or increased costs. Furthermore, the highlighted tumbles and socket of the state of the art can be limited to applications with components that are able to resist high introductory workers. Brief presentation

[0016] With further reference to Fig. 2 shows the lower section 88 a base line 110 In addition to a basic 114 on, whereby the base line 110 A limit between the lower section 88 And the basics 114 of the 64 forms. The Basican 114 extends from the base line 110 and gradually narrowed into a foot in diameter 116 , the one footing 118 has. The foot 116 shows a smaller diameter both and the lower section 88 as well as the base line 110 on, whereby the foot end 118 an upper limit of the foot 118 forms and a front end 120 A lower border of the foot 116 forms.
[0017] It is considered that the bolt 60 A thread can have at least part of the shaft along 64 is arranged. Furthermore, the upper section 86 and the lower section 88 have different heights and diameters and can have the first and the second groove 92 ,, 96 Additional grooves contain. Furthermore, the front end can 120 rounded, pointed, angled or trained in another suitable form.
[0018] With reference to Fig. 3 is a limiter 130 with a edge 132 that near an upper end of a boundary tube 134 is arranged. The edge 132 Passes a cylindrical edge side 136 on, which next to an upper edge area 138 is arranged. The upper edge area 138 is next to a curve 140 that generally rounded and concentric inside the edge 132 is arranged. The curve 140 sits over an inner pipe surface 142 the one from the edge 132 Vertically stretched away to an inner passage 144 to form. Furthermore, the boundary tube 134 an outer pipe surface 146 on, the parallel to the inner pipe surface 142 runs, the outer pipe surface 146 Between a lower edge area 148 and a lower pipe edge 150 stretches. Accordingly, the edge is 132 At an end that ends the end, the lower edge of the pipe 150 has, opposite, with the boundary tube 134 coupled.
[0019] Now with reference to Fig. 4 is the lower edge of the pipe 150 shown more clearly. The lower pipe edge 150 Contains a lower pipe surface 152 , which is flat and circular and from a lower pipe opening 154 is crossed. The lower tube opening 154 Is with the inner passage 144 of the boundary tube 134 concentric, whereby the shaft 64 of the bolt 60 it is permitted to pass through in use there, as described in more detail below. Furthermore, the outer pipe surface extends 146Between the lower pipe edge 150 and the lower edge area 148 . The connection between the lower edge area 148 and the outer pipe surface 146 Is by a pipe neck 156 Formed, the ring in an upper end of the boundary tube 134 is arranged. The lower edge area 148 , the edge side 136 and the upper edge area 138 form the edge together 132 of the boundary tube 130 .
[0020] Fig. 5 shows a cut view of the limiter 130 . The inner passage 144 of the boundary tube 134 is configured to do this, the shaft 64 of the bolt 60 to record. To promote this interaction, contain the inner pipe surface 142 and the outer pipe surface 146 several approaches 158 that between the edge 132 and the lower edge of the pipe 150 are positioned. The several approaches 158 are trained as crooked humps, which are in the inner passage 144 of the boundary tube 134 protrude. The several approaches 158 are configured with the middle waistband 90 of the bolt 60 to work together as in Fig. 9 is illustrated. So the several approaches are 158 Configured so that they are up to a depth in the inner round 144 protrude that to hold the bolt 60 In the limiter 130 is sufficient. With another reference to Fig. 5 shows the edge side 136 a diameter d '' that greater than a diameter d '' '' of the border tube 134 is. In addition, the boundary tube shows 134 a height h, the one between the lower edge area 148 and the lower pipe surface 152 is defined.
[0021] The approaches 158 can be deformed by deforming the outer pipe surface 146 and the inner pipe surface 142 For the creation of a semicircle, for example with a press machine that has a rounded tip. In addition, the several approaches can 158 three approaches 158 contain as in Fig. 3 is shown. It is considered that the several approaches 158 are formed in a different way, such as 3D printing, additive production or other suitable means of manufacture. Furthermore, the several approaches can 158 More or less approaches 158 contain that around the boundary tube 134 are arranged around, such as two, four, five or even six approaches. In addition, the several approaches can 158 From a different material than the boundary tube 134 be formed and can include a polymer, a alloy or composite material. Furthermore, the several approaches can 158 Further away from or closer to the lower pipe edge 150 as shown here.
[0022] Now with reference to Fig. 6 is an embodiment of a spout 180 illustrate, with the spout 180 a central round 182 has that through a central wall 184 Within an upper tumor section 186 is defined. The upper tumor section 186 Contains an upper pleated area 188 , which is circular around a central ring 190 , concentrically along the upper tumor section 186 is arranged. The central ring 190 extends from the upper tumbling surface 188 and is crooked down to the central wall 184 of the central round 182 angled. The upper tumor section 186 Contains an outer wall 192 that of the central wall 184 opposite, the outer wall 192 In addition to an upper curve 194 the upper pleated surface 188 is positioned. The upper curve 194 the upper pleated surface 188 is concentric around the outside of the upper tumbling surface 188 arranged around. Several noses 196 Are under the upper till section 186 trained.
[0023] Like in Fig.7 is illustrated, every nose shows 196 an arm 198 And a body 200 on, whereby the arm 198 On a lower plug surface 202 At the upper tumor section 186 is attached. Every arm 198 Connects the lower tumbling surface 202 With the associated body 200 every nose 196 . How illustrated is the arm extends 198 In an angle from the lower tumbling surface 202 Way to an upper nose end 204 , generally perpendicular to the arm 198 and compared to a lower end of the nose 206 is arranged. The lower end of the nose 206 Contains a lower nose edge 208 . Furthermore, every nose 196 A few nasal side walls 210 on. The several noses 196 Are by column 212 separated, which next to every nasal side wall 210 are positioned so that every nasal side wall 210 The nasal side wall 210 another nose 196 is reversed and opposite her. Every gap 212 stretches vertically from the lower tumbling surface 202 down and next to every nose 196 .
[0024] With further reference to Fig. 7 parts the arm 198 And the body 200 the nose 196 A nasal wall 214 that is shown here in a triangular shape that is at a point between the lower surface 202 and the body 200 Smoked. The inside of the nose 214 Is at an angle with regard to the central wall 184 arranged so that the body 200 every nose 196 Inward of the central wall 184 is positioned. The inside of the nose 214 is crooked and continuously on every nose 196 . In addition, the lower end of the nose is 206 every nose 196 shown as a rounded quarter circle, which is also crooked and continuous. Every nose 196 Contains an outer arm area 216 and an outer body area 218 , the one from the upper nose end 204 be crossed in between. The spout 180 and the several noses 196 are configured with the bolt 60 and the limiter 130 to have a compilation, as described below.
[0025] Now with reference to Fig. 8 are the bolt 60 , the limiter 130 And the spout 180 shown in a pre -assembled state. The shaft 64 of the bolt 60 Is through the inner passage 144 of the boundary tube 134 introduced, and the bolt 60 And the limiter 130 are together in the central round 182 the spout 180 introduced. Here is only part of the upper section 86 of the 64 The one above the edge 132 to see. So the shaft is 64 not fully in the boundary tube 134 introduced.
[0026] Like from the Fig. 9-11 can be seen, further assembly steps show the installation of the bolt 60 , the limiter 130 and the spout 180 on a plate 220 with an opening 222 in it. In Fig. 9 is the shaft 64 to a depth similar to the pre -assembly state of Fig. 8 illustrated. In order to achieve this pre -assembly state, a user leads the front end 120 of the 64 of the bolt 60 In the inner round 144 of the boundary tube 134 a. The user practices down the downpower on the head 62 of the bolt 60 out to the middle covenant 90 About those through the several on the boundary tube 134 arranged approaches 158 to press out the pressed recourse. The middle covenant protrudes to illustrate 90 In the representation over the diameter D of the 64 In addition, which provides a threshold to be overcome before reaching the pre -assembly state shown here. The several approaches 158 work with the first groove 92 , the beveled edge 98 and the federal level100 Together to the bolt 60 to hold on to its vertical and concentric position. The front end 120 of the 64 Touched the nasal wall 214 of the several till noses 196 .
[0027] In this pre -assembly state, the boundary tube is 134 partly in the central round 182 the spout 180 Just above the plate 220 introduced. So the bolts are 60 , the limiter 130 And the spout 180 Pained together so that you can move at least one of the components together by taking. Furthermore, the lower tiller area is 202 pressed down to the first platform side 224 to touch. Accordingly, the several noses extend 196 through the opening 222 the plate 220 , and every body 200 is then under a second platform side 226 . Every arm 198 Is in the opening 222 the plate 220 positioned, but without the plate 220 to touch yourself.
[0028] Like in Fig. 10 is shown, the next step is an intermediate assembly state that the foot 116 of the 64 Among the several noses 196 Promises. A user can exercise an additional or larger down force to the head 62 of the bolt 60 in contact with the edge 132 of the limiter 130 bring to. In particular, the lower flange touches 78 The upper edge area 138 to further insert the shaft 64 In the inner round 144 of the boundary tube 134 to prevent. The one on the head 62 Downturns created must 158 With the first beveled edge 98 overcome resistance provided. The several approaches 158 Now work with the upper section 86 of the 64 Together to the bolt 60 To give stability. Furthermore, the covenant recess is 104 of the middle covenant 90 Next to the lower edge of the pipe 150 positioned.
[0029] With further reference to Fig. 10 are the several noses 196 in a pattern of the foot in a pattern 116 And the basics 114 Way and pushed through it. Accordingly, the front end move 120 And the shaft 64 of the bolt 60 through the column 212 downward. This is expanded or expanded by every arm 198 and its elastomer material properties. Like from the Fig. 9 and Fig. 10 emerges in this intermediate assembly state the limited tube is 134 still partially in the central round 182 the spout 180 introduced and the lower edge of the pipe 150 Stay above the first platform side 224 and opening 222 positioned. So every arm sits 198 still in the opening 222 , without the plate 220 to touch.
[0030] Finally illustrated Fig. 11 a assembled condition, with the boundary tube 134 now completely through the central round 182 the spout 180 is introduced. The central wall 184 Is now on the inner nasal walls 214 aligned that have expanded to the outside world to form a straight line along it, as in Fig. 11 is shown. The upper nose end 204 Touched the second platform side 224 , and every outer arm area 216 Touched the plate 220 in the opening 222 . As a result, the spout is 180 positioned in this, the bolt 60 and the limiter 130 With the plate 220 to hold on. The lower section 88 and the foot 116 of the 64 Both stretch under the lower nasal edge 208 . The lower edge of the pipe is also 150 Now on the lower nose edge 208 Aligned, which indicates that the assembled state has been reached.
[0031] The fastening element arrangement can alternatively contain a holding, which a fastening element securely on the edge 132 of the limiter 130 Clamped. The US patent registration no. 15 / 691.848 entitled "Fastener Assembly Having One Or more grommet" (fastening element arrangement with one or more tumes), which is transferred to Illinois Tool Works in GlenView, Illinois and is hereby fully recorded by reference, a fortification arrangement, for example in the Fig. 9a and Fig. 9b that contains a holding, which clamps the head of a fastening element safely on the flange of the socket or the limiter. Holding contains an inner lead that is safely clamped over a radial outer edge of the head. The lead is connected by a ring -shaped circumference wall with an external circumference. The clamp is securely attached below an outer edge of the flange. In this way, the holding is safe with the socket or the limiter. In some embodiments, holding can turn freely when sticking to hold and can therefore, for example, with a threaded rod or a cone as an alternative to a bolt 60 be used.
[0032] Like in Fig. 12 is shown, a different embodiment of a limiter can 230 for example a cylinder 232 contained that several by an outer cylinder area 236 ribs arranged around 234 has that between a cylinder flange 238 and a lower cylinder edge 240 are arranged. The several ribs 234 Can elliptical shapes with a rounded upper part 242 and a rounded lower part 246 have. If the several ribs 234 In the central round 182 the spout 180 You can be introduced, the friction and holding forces that are through the central wall 184 and the inner nasal walls 214 be provided, increase. In this way the spout becomes 180 Through the several ribs 234 more safely recorded.
[0033] With reference to Fig. 13 In some embodiments, the several ribs can 234 In addition to several approaches (not shown), which on an inner cylinder area 248 are arranged. It is considered that three ribs 234 On the outer cylinder area 236 can be intended, as in Fig. 13 is shown. Alternatively, any number of ribs can 234 On the outer cylinder area 236 to be intended to keep an increased friction and an increased keeping between the spout 180 and the limiter 130 to promote. Like in Fig. 14 is illustrated, each of the several ribs can 234 With a rib hollow room 250 be created or trained.
[0034] Now with reference to Fig. 15 can still have a further embodiment of a limiter 252 A drum 254 With a wavy section 256 that several surveys 258 and depressions 260 contained along this. The several depressions 258 that from the drum 254 protrude and radially in a tromnail transfer 262 are arranged, provide a press coverage for the tromnail transfer 262 introduced shaft 64 of the bolt 60 Ready that fully through the limiter 252 stretches. Furthermore, the several surveys can 258 that from the drum 254 protrude and radially around the corrugated section 256 are arranged, friction and holding forces who are experienced while the drum 254 Through the central round 182 the spout 180 is introduced. In this way, the corrugated section increases 256 Holding in both the bolt 60 as well as the spout 180 With the limiter 252 .
[0035] With reference to Fig. 16 are three of the surveys 258 To the drum 254 shown around, which are due to the fact that the wavy section256 It is trained to form a triangular shape of how this sub -view is illustrated. It is considered that a larger number of surveys 258 by creating the wavy section 256 for another form, such as a square or a hexagon. In a similar way, the number of depressions can 260 (in Fig. 15 to see), that with the shaft 64 of the bolt 60 interaction, by varying the shape of the corrugated section 256 can be increased or reduced.
