CIRCUIT PROFILE

Description

Technical field

[0001] The invention relates to a switching profile according to the preamble of claim 1 and a method for its manufacture according to claim 8. State of the art

[0002] Such switching profiles are already known and commonly used in a variety of forms and designs.

[0003] For example, EP 1 926 113 A1 discloses a ramp profile, in particular for doors or gates equipped with a drive, which reacts to a pressure signal, with a rubber profile that has a switching chamber for receiving at least one force-operated switching strip and / or a pressure wave contact device as switching element(s) and a ramp strip that is force-transmittingly connected to the switching chamber, wherein the clear cross-section of the switching chamber is variable in size, wherein pivotable lever arms, such as flanges, webs, projections or the like, are associated with the switching chamber, by means of which the switching chamber can be varied in size when pivoted for mounting the ramp profile, wherein the switching element is inserted into the switching chamber before the lever arms are pivoted for mounting and is held in the switching chamber without play by pivoting the lever arms for mounting.

[0004] DE 298 04 732 U1, for example, shows such a ramp profile, which is attached to a roller door with a curtain running in guide rails, made of interlocking bars. The bottom bar serves as an end strip in the form of an elastic ramp profile made of rubber. This ramp profile has an upper switching chamber for accommodating a force-transmitting switching strip and a lower chamber for pressure wave contact detection. The two chambers are connected by a web for pressure transmission. The aim of this double-chamber design of a switching element is to simplify inventory management; that is, where previously two separate switching elements were required depending on the application of a switching strip or a pressure wave device, both systems are now combined in a single switching element, allowing it to be used interchangeably.

[0005] German patent DE 298 08 292 U1 discloses a rubber end profile for vertically lifting and lowering gate leaves. The leading edges or rims in the closing direction are provided with a tubular channel in which a pressure-responsive switching device is arranged. Since the switching device responds to pressure, the clear cross-section of the switching chamber can be varied in size during operation. The contact strips can only be compressed by changing the aspect ratio of the chamber. The pressure is transmitted via the test bars. The described switching device is designed to be more sensitive, meaning it responds even to lower forces. This is achieved by providing slots in the lower section of the channel wall.These slots create easily deformable strips and edge strips, so that the switching device arranged in the channel is actuated even with much lower forces acting on the end profile.

[0006] In this context, reference is also made to the following publications: In DE 94 03 972 U1, an elastically deformable edge protection profile with switching elements of a circuit for controlling a translational movement of one component relative to another component is disclosed.

[0007] EP 3 023 280 A1 discloses a protective device that is coupled to a sliding door and detects objects by contacting two conductive parts in a hollow body. Object of the invention

[0008] The object of the present invention is to overcome the disadvantages of the prior art. In particular, it aims to provide a switching profile that can be manufactured quickly and cost-effectively, requires less assembly time, and exhibits optimal sensitivity. Solution to the task

[0009] The features according to claims 1 and 8 lead to the solution of the problem.

[0010] Advantageous embodiments are described in the dependent claims.

[0011] A switching profile according to the invention has a switching head, a first side wing and a second side wing, wherein a concave profile and a convex profile are arranged in an interior of the switching head in alignment with each other, wherein the switching head consists of a base, a first side flank and a second side flank, wherein the first side flank projects away from the base at one end and transitions into a vertex at the other end, wherein the second side flank projects away from the base at one end and also transitions into the vertex at the other end.

[0012] In this process, all essential parts of the switching profile are extruded in a single piece in one and the same step. The switching profile serves to secure gates, doors, or similar devices. When the switching head is compressed, the concave and convex profiles come into contact, thereby generating or interrupting a signal. This process, in turn, is used to stop or reverse motorized automatic doors, for example, to protect trapped body parts from injury.

[0013] An advantage of this is that assembly times for the switching profile according to the invention can be considerably reduced. Furthermore, it is advantageous that self-assembly by the end user is possible. In addition, the switching profiles can be manufactured cost-effectively as pre-assembled strips and delivered to the customer for easy installation.

[0014] The flat switching profiles can be produced more easily due to their low profile, resulting in more accurate and simpler reproducibility. This, in turn, leads to higher production speeds and cost reductions in manufacturing.

[0015] Preferably, a first binding point is provided between the switching head and the first side wing, with a first folding groove arranged at the first binding point. The first folding groove serves to make the first side flank easier and more readily pivotable. The binding point represents a thinning of the material.

[0016] Preferably, a second binding point is provided between the switching head and the second side wing, with a second folding groove arranged at this second binding point. The second folding groove serves to make the second side flank easier and more readily pivotable. The second binding point also represents a material thinning.

[0017] According to the invention, a first convex strip is formed on the first side flank, extending towards the convex profile. Similarly, a second convex strip is formed on the second side flank, extending towards the convex profile. The convex strips serve to improve the return of the switching head after the concave and convex profiles have made contact.

[0018] Preferably, the concave profile has a rounded base into which the convex profile partially projects. In the event of compression of the switching head, the convex profile is positively engaged with the rounded base.

[0019] Preferably, a first connecting piece and a first support flap are formed on the first side wing, and a second connecting piece and a second support flap are formed on the second side wing. The connecting pieces and the side wings are integral components of the two side flanks and, due to the material properties of rubber, possess sufficient stiffness and flexibility to connect the switching profile to a receptacle on a gate or door.

[0020] The switching head, the two side wings, the concave profile, and the convex profile are extruded in one piece. Similarly, the convex strips are also integrally formed as a single piece with the switching head.

[0021] The process for manufacturing a switching profile is primarily characterized by the fact that the switching head, the two side wings, the concave profile and the convex profile are extruded in one piece, with a strand also being extruded along with it. Character description

[0022] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings; these show in: Figure 1: A cutaway side view of a switching profile in its rest position; Figure 2: An enlargement of a part of the Figure 1 Figure 3 shows a side view of the switching profile in working position. Example of implementation

[0023] In Figure 1A sectioned side view of a switching profile 1 is shown. The switching profile 1 primarily consists of three elements. A switching head 4 is shown centrally. A first side wing 2 and a second side wing 3 are extended from the switching head 4.

[0024] Furthermore, excerpt 5 is shown, which is in Figure 2 shown enlarged.

[0025] At the point where the first side wing 2 is formed on the switching head 4, a first folding groove 6 is shown. The first folding groove 6 tapers towards a first binding point 26. Similarly, a second folding groove 7 is formed at a second binding point 27. The second folding groove 7 also tapers towards the second binding point 27. The first folding groove 6 and the second folding groove 7 are open and project away from the switching head 4.

[0026] At one end, the first side wing 2 has the first folding groove 6. At the other end, the first side wing 2 has a first connecting piece 8. The first connecting piece 8 is an expansion element in the form of a hollow rubber profile. A first support flap 10 is also formed between the first connecting piece 8 and the first folding groove 6. The first connecting piece 8 and the first support flap 10 project from the same side of the first side wing 2.

[0027] A second folding groove 7 is shown at the point where the second side wing 2 is formed onto the switching head 4. The second folding groove 7 tapers towards a second binding point 27.

[0028] At one end, the second side wing 3 has a second folding groove 7. At the other end, the second side wing 3 has a second connecting piece 9. The second connecting piece 9 is also an expansion element in the form of a hollow rubber profile. A second support flap 11 is also formed between the second connecting piece 9 and the second folding groove 7. The second connecting piece 9 and the second support flap 11 project from the same side of the second side wing 3.

[0029] Furthermore, a center line 16 is shown, which runs perpendicular to the section view and centrally through the switch head 4.

[0030] The switching head 4 incorporates a concave profile 12 and a convex profile 13. The switching head 4 primarily consists of a base 28, a first side flank 21, and a second side flank 22. In its rest position, the base 28 lies essentially in the same plane and between the first side wing 2 and the second side wing 3. The base 28 is formed between the first folding groove 6 and the second folding groove 7, transitioning into the first side flank 21 on one side and the second side flank 22 on the other. The two side flanks 21 and 22 meet at a vertex 19.

[0031] The switching head 4 has a triangular design and encloses an interior space 29, with the apex 19 representing a rounded surface which transitions on one side into the first side flank 21 and on the other side into the second side flank 22.

[0032] In the interior space 29, the concave profile 12 is arranged on the base 28. The convex profile 13 is arranged on the vertex 19 opposite the base 28. The convex profile 13 projects convexly away from the vertex 19. Viewed from the vertex 19, the concave profile 12 forms a concave rounded base 20, into which the convex profile 13 partially projects in its operating position. When the switching head 4 is compressed, the convex profile 13 moves into the rounded base 20 of the concave profile 12, thereby triggering a signal. This signal is then processed to stop one process or start another.

[0033] Furthermore, on the first side flank 21, within the interior space 29, a first convex strip 14 is formed with the convex profile 13. Furthermore, on the second side flank 22, within the interior space 29, a second convex strip 15 is formed with the convex profile 13. In section view, the first convex strip 14 and the second convex strip 15 have an arc shape that projects away from the side flanks 21 and 22.

[0034] To move switching profile 1 from the rest position to the working position, as described in the Figure 3 As shown, the two side flanks 21, 22 are brought towards the center line 16. The direction is indicated by the first directional arrow 17 and the second directional arrow 18.

[0035] In Figure 2 is an enlarged section of the Figure 1 shown. The features shown there are already in the Figure 1 The explanations regarding Figure 1 should also be for the Figure 2 apply.

[0036] In the working situation as it exists in Figure 3 As shown, the convex profile 13 partially protrudes into the concave profile 12, so that there is only a distance of 1 to 5 mm between the concave profile 12 and the convex profile 13.

[0037] The switching profile 1 is attached to a mounting profile 23. The mounting profile 23 has a first side recess 24 and a second side recess 25. The first connecting piece 8 is inserted into the first side recess 24. The support flap 10 rests on the first side recess 24.

[0038] In the same way, the second connecting piece 9 is inserted into the second side recess 25, with the second support flap 11 coming to rest on the second side recess 25.

[0039] A stranded wire is present in the concave profile 12 and / or the convex profile 13.

[0040] Although only one preferred embodiment of the invention has been described and illustrated, it is obvious that the person skilled in the art can add numerous modifications without departing from the essence and scope of the invention.
