PROFILE WITH INTEGRATED SWITCHING ELEMENT OF A CIRCUIT

Description

[0001] The present invention relates to a profile according to the preamble of claim 1.

[0002] Reed switches, also called reed contacts, are switching elements in a ferromagnetic circuit. This type of switching element comprises a switching element, such as ferromagnetic switching reeds, which are located in a rod-shaped housing. The housing is preferably designed to hermetically seal the switching elements against the environment. Suitable housing materials can be made of glass or plastic, for example.

[0003] The switching reeds can be caused to move relative to one another by external influences, in particular a magnetic field, so that the circuit closes when a magnetic field approaches. The magnetic field can be generated by permanent magnets or coils. This magnetic field is provided by a trigger element of the circuit. If the reed switch is integrated as a switching element in a first profile of a window, the trigger element can be provided in a second profile of the window, with one of the profiles being mounted so as to be movable relative to the other profile of the window, such that the two profiles change the switching state of the switching element when approaching.

[0004] Reed contacts are well known in window construction. They are a single-piece construction, comprising a contact cable and an end stop on the reed contact housing. Installation within a profile is problematic with reed contacts. Reed contact cables can be several meters long. During on-site installation, the reed contact cables must first be threaded through a hole in the profile. The reed contact housing is then inserted into the hole in the profile up to the end stop. Threading the contact cable through the profile is time-consuming during on-site installation, and the window sash may need to be supported.

[0005] Another approach was to pre-assemble the reed contacts at the factory. This provides both the necessary space and, if necessary, installation aids to guide the reed contact cables through the window profile somewhat more quickly. The problem with this approach is that the contact cables can be sheared off or otherwise damaged by the weight of the window during subsequent transport.

[0006] DE 10 2007 032 504 A1 discloses a two-part reed switch with a socket and a replaceable sensor element. The socket must also be inserted by threading the cable through the profile. Although the sensor element is replaceable, the assembly sequence and the insertion of the cable through the sensor socket and the attached stop collar into the profile are fixed.

[0007] Based on the above-mentioned task, the object of the present invention is to provide a profile with an integrated switching element, which can be mounted in a profile body of the profile in a much simpler and faster manner.

[0008] The present invention solves this problem by a profile with the features of claim 1.

[0009] The profile according to the invention can be used for doors, windows, frames or also in facade constructions.

[0010] The profile has a profile body. This profile body encompasses an opening, for example the opening of a bore. The profile further has an arrangement comprising a switching element inserted into the opening. The switching element is part of a circuit, in particular a circuit with a magnetically triggered switching function. The circuit typically extends over multiple profiles. The switching element can be a reed contact, which is triggered by a magnet of another profile that is movable relative to the profile according to the invention, wherein the reed contact is triggered when the magnet approaches. Of course, the profile according to the invention can also be movable relative to the profile with the magnet.

[0011] In contrast to the prior art, the assembly installed in the opening features, in addition to the switching element, a separate retaining element with a linear stop. This serves to limit the linear movement of the assembly within the opening of the profile body.

[0012] According to the invention, the switching element has a terminal cable. The retaining means is designed such that it can be mounted from a direction perpendicular to the longitudinal direction of the cable. For this purpose, the retaining means, in particular the armature sleeve, has a slot that extends over the entire length of the retaining means. By widening the slot, the cable can be positioned in the interior of the retaining means or the armature sleeve without having to be inserted through the retaining means at the terminal end and threaded through the entire cable length.

[0013] This allows the switching element to be guided through the opening from the rear. It can then be connected to the retaining element at the front to form the assembly and finally placed in the opening. Threading the entire length of cables through the opening is not necessary with this variant, thus significantly simplifying installation.

[0014] Advantageous embodiments of the invention are the subject of the dependent claim.

[0015] The separate retaining means can preferably be designed as an anchor sleeve, wherein the anchor sleeve comprises a sleeve body, preferably of a cylindrical configuration, and the linear stop. The sleeve body and linear stop are integrally connected to one another in the anchor sleeve. The linear stop is preferably arranged at the end of the sleeve body. As a result, the arrangement advantageously protrudes only slightly from the profile body.

[0016] The linear stop can advantageously be designed as a ring disc in order to achieve an even force distribution and support.

[0017] The anchor sleeve can be connected to the switching element in a form-fitting or force-fitting manner. This essentially corresponds to the function of a conventional expansion anchor.

[0018] The holding means, in particular the anchor sleeve, can be designed as an expansion sleeve with at least one second non-continuous slot to reinforce the anchoring of the holding means in the opening of the profile body.

[0019] To improve the spreading effect, the second slot is particularly long. Therefore, it is advantageous if the second slot extends over at least 80% of the sleeve body.

[0020] The maximum diameter of the switching element or its radial extent is smaller than the diameter of a bore in the profile body in which the arrangement of holding means and switching element is arranged or the opening in the profile body associated with the bore in which the arrangement of holding means and switching element is arranged.

[0021] The switching element can advantageously have a linear stop for limiting the linear movement of the switching element relative to the holding means, in particular the armature sleeve.

[0022] The switching element can have a terminal locking means. This can preferably be designed as a locking ring, particularly preferably a locking ring with at least one slot interrupting the ring contour, in order to enable a particularly secure and at the same time releasable attachment of the switching element by the holding means. The locking means serves to limit the linear movement of the switching element relative to the holding means or the armature sleeve.

[0023] The switching element can advantageously be fixed, preferably releasably fixed, within the holding means, preferably the armature sleeve, by the locking means, in particular by the locking ring and the linear stop.

[0024] The holding means, in particular the anchor sleeve, can have radial ribs which protrude radially from the sleeve body in order to reinforce the radial clamping or the form fit.

[0025] The linear stop of the armature sleeve can advantageously be flush with the linear stop of the switching element, forming a common end face of the assembly consisting of the armature sleeve and switching element. This means that the outwardly protruding area of ​​the assembly presents only a minor obstacle compared to the profile body, and at the same time, only a small amount of dirt can accumulate in this area.

[0026] The arrangement can advantageously include a separate cover cap, which is preferably arranged over the end face. This can advantageously prevent damage to the linear stop and thus slippage of the switching element within the profile body.

[0027] The present invention is described in more detail below using several exemplary embodiments and the accompanying drawings. They show: Fig. 1: Perspective view of the components of a profile according to the invention during two assembly steps; Fig. 2: Perspective view of the components of the profile during a third assembly step; Fig. 3: Enlarged perspective view of an anchor sleeve as one of the aforementioned components; and Fig. 4: Sectional view of the profile according to the invention.

[0028] Fig. 1-4 show the components of a profile 1 according to the invention with an integrated switching element 4 having a longitudinal axis A. This switching element 4 is preferably designed as a so-called reed contact. The reed contact can be used to implement, among other things, burglar protection, opening protection, and monitoring of the opening state within the framework of building management.

[0029] The profile has a profile body 2 with a bore 21 for receiving an arrangement of switching element 4 and an armature sleeve 3 in the profile body 2 and an opening 17 for access to the bore 21. The armature sleeve 3 has a longitudinal axis B, which, in the assembled state, is arranged coaxially to the longitudinal axis A of the switching element 4.

[0030] The switching element 4 has a rod-shaped body 6 with an outer surface. This can preferably be a cylindrical surface, but also a cuboid surface or prism surface, or the like.

[0031] Preferably, the switching element 4 has a linear stop 7 at its end for limiting the linear movement of the switching element 4 along its longitudinal axis during its relative movement with respect to the armature sleeve 3 when the switching element is inserted into a sleeve opening 16.

[0032] The anchor sleeve 3 has a sleeve body 19, preferably of cylindrical design, and radially projecting ribs 14 to improve the force and / or frictional connection between the profile material and the anchor sleeve. As is known, such ribs in anchors and the like increase the radial forces on the adjacent material, in this case the profile material.

[0033] The armature sleeve 3 is designed as an expansion sleeve with two longitudinally extending slots 12 and 13. One of the slots 12 extends continuously over the entire length of the armature sleeve, so that the sleeve is open in some areas and thus a cable 5 of the switching element can be guided through the slot 12 into the interior of the sleeve.

[0034] Furthermore, the anchor sleeve has a preferably terminal linear stop 10 on the sleeve body 19 for abutment with the opening 17 of the bore 21. The linear stop 10 can be designed as an annular disc-shaped head segment which protrudes radially relative to the sleeve body 19.

[0035] Said slot 12, as a radial segment 11, runs in particular also through the linear stop 10. The second slot 13 runs only through the sleeve body 19 and preferably extends over more than 80%, preferably between 81-97%, of the length of said sleeve body. The long expansion zone of the anchor sleeve 3 counteracts low compressive strength.

[0036] The sleeve body 19 defines a smaller inner diameter than the terminal sleeve opening 16, resulting in a stepped opening geometry with a stop edge 15, which is also a terminal end face of the sleeve body 19. Finally, the armature sleeve 3 has an inner guide edge 20 on the side opposite the linear stop 10, which allows additional guidance and, if necessary, additional force-locking between the armature sleeve 3 and the switching element.

[0037] In the assembled state, the linear stop 7 rests on the stop edge 15, so that a blocking of the linear movement of the switching element 4 relative to the armature sleeve 3 in a first direction is achieved. This is particularly important in Fig. 4 recognizable.

[0038] Furthermore, the switching element 4, also preferably at the end, has holding means 8, in particular locking means, which are connected to a corresponding recess or edge of the armature sleeve by clamping or preferably by positive locking. This blocks the linear movement of the switching element 4 relative to the armature sleeve 3 in a second direction and the switching element 4 is linearly fixed, preferably releasably fixed, in the armature sleeve 3. The holding means 8 is designed in particular as a locking ring with a circumferential edge nose. The locking ring 8 is in turn interrupted by a slot 9 or several slots in the longitudinal direction to the longitudinal axis A to improve the deformability of the locking ring in the radial direction. The locking ring 8 is preferably set back from the body 6 and also preferably arranged at the end of the body 6. Furthermore, the locking ring 8 can lock or clamp with the inner guide edge 20 of the armature sleeve 3.

[0039] As already explained, a comparatively long contact cable 5 leads from the switching element 4.

[0040] For assembly, in a first step 100, the switching element 4 including the cable 5 is threaded through the bore 21. This already represents a significant difference from the prior art, in which previously only the rear cable 5 was threaded through the bore 21 and the reed contact was positioned as far as it would go in the bore 21. The radial dimension of the switching element 4 is smaller than the opening cross-section of the bore.

[0041] Then, in a second step 200, the cable 5 is passed vertically through the slot 12. This slot can be widened if necessary. For this purpose, the anchor sleeve 3 is made of an expandable plastic material, such as that used in commercially available expansion anchors. A polyamide, in particular nylon, is particularly preferred.

[0042] As can be seen from the figures, the holding means in step 200 is designed to be mountable from a direction perpendicular to the longitudinal direction of the cable 5.

[0043] The armature sleeve 3 is then slipped over the switching element 4 or the switching element 4 is inserted into the armature sleeve 3. The armature sleeve has a wider radial dimension in some areas, particularly in the area of ​​the linear stop 10, than the opening diameter 17 of the bore 21. Thus, the arrangement of the armature sleeve 3 and switching element 4 strikes the profile body 2.

[0044] Finally, the assembly is inserted into the bore. The assembly is held in position by the ribs 14 and the linear stop 10. A cover cap 18 can then optionally be placed on the linear stop 10.

[0045] This type of installation reduces the installation effort of threading several meters of cable 5 by inserting it through in opposite directions and then fastening the switching element 4. The installation can be carried out in a very short time without any additional tools, even on site, i.e. at the place where the window is installed. List of reference symbols
