EP3333351B1 - Connection assembly for connecting a post with a frame profile of a window or a door made of plastic - Google Patents

Description

The invention relates to a connection arrangement for connecting a post with a frame profile of a window or a door made of plastic, wherein the post has a hollow profile and is secured to the frame profile by means of a post connector having a base part which is mounted on the frame profile, and an over this arranged Aufsetzteil comprises, which is connected to the post and is positively guided when plugging onto the base part, wherein in the assembled state Aufsetzteil and base are fastened together.

A connection arrangement of this kind is z. B. in the EP 2 354 419 A2 described. For assembly, the base part of the post connector is placed on a profiled top of a frame profile and fastened there via several screws on this.

The Aufsteckteil in turn projects beyond an upper mold section in the hollow section of the post, where it is positively inserted into the latter so far until the lower end surface of the post against the upper support surface of the Aufsteckteiles comes to a stop. About mounted in Aufsteckteil bores of the inserted into the hollow profile of the post upper mold portion of the Aufsteckteiles be fastened by means guided through the holes screws on the post. On the base part as well as on the Aufsteckteil also extending in the longitudinal direction of the frame profile, mutually aligned bores are mounted so that in the assembled state, a through hole passing through the two parts through hole is formed. By a suitable introduced into this fastener, such as a correspondingly long screw or a through-bolt o. Ä., Then the desired firm connection between the base part and Aufsteckteil can be created, which blocks the relative position of both parts to each other.

Although this known post connector overall allows a relatively quick and convenient installation, but in which a plurality of screws are required both for attachment of the base part on the frame profile, as well as the connection between Aufsteckteil and connected to this post, which in the assembly of such post connectors yet always a significant effort for attaching the necessary holes for the screws, also on the frame profile, as well as for the screwing of the screws due

A connection arrangement with the features of the preamble of claim 1 is made DE 197 45 750 A1 known.

On this basis, the invention aims to improve a connection arrangement of the type mentioned so that it can be mounted faster with a simplified installation effort.

According to the invention, this is achieved in a connection arrangement of the type mentioned above in that the Aufsteckteil and the base part each locking elements are provided, by means of which the Aufsteckteil on the post and the base part on the Rahmenprofi are positively fastened latching during assembly.

Through the use of locking elements between Aufsteckteil and posts and base member and frame profile through which a mutual positive-latching attachment can be achieved when placing the items in the assembly, the possibility is created in the invention, both the attachment of the base to the frame profile, as well to be able to make the Aufsteckteiles on the post entirely without screws. This leads to a much faster assembly, since neither the screwing of screws, nor the attachment of the necessary screw holes in the base and in the plug-in part and in the connected frame profile or post is required. It can also be the cycle time in an automated production line, which is currently at two minutes per clock, lower and thereby achieve an acceleration of the assembly. Because in the automated assembly of known post connectors, in which the cycle time is usually, as mentioned above, two minutes, but a much longer duration of the clock must be considered when attaching and fastening screws. This means that for this purpose the frame to be mounted must be separated on a special workplace, while in the tact line with a blank space is continued. To re-insert the frame in the bar, however, a new space is then required, which must be created at the beginning of the bar, but there must be nothing done until reinserting at weiterlaufendem tape. Taking these processes into consideration, this leads to a loss of time of four minutes, which, since approximately 240 frames can be created in known tact streets in approximately eight hours, results overall in a noticeable increase in assembly speed.

In addition, the invention also leads to a lower use of materials, since the screws to be used in the known post connectors for their attachment to the frame or post replacement omitted. In this case, the locking elements used in the invention on the male part and the base part easily during injection molding of these plastic parts together be prepared with these, so that no additional manufacturing steps are required for this. The required for the production of the locking elements additional cost of materials is very low, especially compared with the cost of materials for the spare attributable screws.

According to the invention it is provided that for the attachment of the Aufsetzteiles on the base part also locking elements are provided on these parts, by means of which both parts can be positively connected to one another in a latching manner. As a result, it is now possible to fasten the base part and the plug-on part without screws, bolts or the like in the mounted state, whereby a further acceleration of the assembly can be achieved.

In the invention, it is particularly advantageous if, during assembly of the connection arrangement according to the invention, the plug-on part can be placed vertically from above onto the base part.

In the invention, it is also advantageous if the locking elements are designed in the form of projecting, elastically deflectable spring hooks which are provided with latching hooks at their projecting ends, each of these latching hooks in the assembled state in each case in an associated receiving opening in a wall of the part to be connected engaging latching. In this case, the elastically deflectable spring hooks are preferably provided at their latching hooks with inlet slopes, which cause during assembly an automatic elastic rebound of each spring hook before its entry into its latching position. The design of the locking elements as such elastically-spring spring hooks, moreover, with inlet slopes on the latching hook, allows a very quick installation by the parts to be fastened to each other are pushed only in the direction of the final assembly position, in which case the elastically spring-spring hooks cause completely automatic shrinkage in the respective Verrastungs end position and thereby no special further handles are required during assembly.

It is also particularly recommended if in the invention, all latching connections are detachable, so that at any time by a suitable solution engagement, a repeal of each created by the relevant locking connection attachment of two parts from each other is possible.

A further advantageous embodiment of the invention is also that all locking elements, which serve on Aufsteckteil and the base part for locking on the post or on the frame section, at the other of the two parts in each case a support member is assigned, which in mounted state of the arrangement bears against the respective associated locking element and this is supported so that a Ausrastbewegung from the detent position is not possible.

It is particularly advantageous if the locking elements are provided in the form of elastically spring spring hooks each with a central, opposite to the projecting end of the spring hook end of the same open center hole, in which the locking element associated with this support member during assembly of the base member and Aufsteckteil insertable is. In this embodiment, the support member is not applied laterally against the spring hook from the outside during assembly, but rather introduced into the center hole mounted in this, so that it supports the spring hook from its interior against a disengagement. In this embodiment, it is recommended that some or all support members are cylindrical.

In the connection arrangement according to the invention, depending on the specific configuration of the parts, at least four, particularly six locking elements for locking the post can be attached to the Aufsteckteil, with a larger or smaller number of such locking elements can be provided.

It is also advantageous in the invention, when projecting on the base part on its underside facing the frame two spring hooks which are provided with latching hooks at their projecting ends which point in opposite directions and together protrude through a hole in the frame profile, wherein the latching hook on Bore exit radially overlap the bore opening. This creates a simple, but very effective embodiment of the locking elements used.

If in the connection arrangement according to the invention the individual locking elements associated support members are used, then it is advisable to provide them with a shape which in the mounted state with a complementary shape either on the support member facing the rear side of the associated locking element or on one of the back the latching element opposite rear side of the support member adjacent wall is in a positive connection, which blocks in a movement against the mounting direction of the Aufsetzteiles on the base member, but allows a movement of the support member relative to the locking element in Aufsetzrichtung. The connection arrangement according to the invention initially results in a particularly rapid acceleration of the assembly, which can be carried out completely without the use of screws. In the case of automatic assembly lines, it is possible to reduce the cycle time for the assembly of the post connector to one second (or even less).

In this case, the connection arrangement according to the invention is also relatively simple in construction, it can be handled easily and it can be used easily on a frame welding machine.

In the accompanying figures, an embodiment of the invention is described in more detail in detail, wherein in the various figures, like parts are given the same reference numerals.

First, the presentation of the Fig. 1 an oblique perspective view of a connection arrangement in which a post 1 (of which only the lower end portion is shown), which is provided with a hollow profile 3, is fixed via a post connector 4 on the top of a post 1 perpendicular to the frame profile 2, wherein the Post connector 4 is shown mounted on a profiled surface of the frame strip 2.

Post 1, frame profile 2 and post connector 4 are all made of a suitable plastic.

The post connector 4, in turn, consists of Fig. 1 is not recognizable and will be described in detail below, from two parts, namely an upper Aufsteckteil 5, from which an oblique view from above in Fig. 2 is reproduced below the representation of the post 1, and a lying in the assembled state below the Aufsteckteiles 5 base part 9 (see 6 and 7 ). In this case, the Aufsteckteil 5 is positively inserted with its upper portion in the lower end portion of the post 1 in the hollow section 3, wherein Fig. 3 represents this Einschiebevorgang, but in a state in which the plug-5 is not yet fully inserted into the post 1.

The Aufsteckteil 5 comprises a base plate 6, from which a plurality of shapes, such as Fig. 2 shows, run vertically upwards, while other shapes that will be discussed, projecting on the bottom of the base plate 6 downwards.

That's how it is Fig. 2 recognizable that protrude from the base plate 6 a plurality of locking elements 7 in the form of elastic spring hooks vertically upwards, each of these locking elements 7 is provided at its free projecting end with a latching hook 8 which protrudes from the locking element 7 perpendicular to the outer side surface.

Now if the Aufsteckteil 5 from below, as in Fig. 3 shown in the hollow section 3 of the post 1 is inserted (this insertion is positively guided by the other shapes above the base plate 6 of the Aufsteckteiles 5, which are supported on inner walls of the hollow profile 3 during insertion) is at a time of insertion, where the base plate 6 comes to rest against the lower end face 10 of the post 1, the insertion process finished.

Within the region of the hollow profile 3 of the post 1, in which the upper portion of the Aufsteckteiles 5 is inserted into the hollow section 3, are at appropriate locations in side walls 12, 13 of the post 1 (FIG. Fig. 3 and 4 ) Holes 11 attached (see. Fig. 2 to 5 ), which pass through the respective side wall 12 and 13 of the post 1.

Fig. 4 shows a sectional view along section AA through the configuration of the arrangement Fig. 2 and Fig. 5 shows the sectional view Fig. 4 , but with completely pushed into the hollow section 3 of the post 1 Aufsteckteil. 5

The presentation of the Fig. 4 shows the arrangement of the through holes 11 in the side walls 12 and 13 of the hollow section 3 of the post 1, which are offset from the lower end face 10 of the post 1 by a distance such that when fully pushed on the plug 5, the locking hooks 8 of the elastic locking elements. 7 completely engaged in the respective associated bore 11.

When inserting the Aufsteckteils 5 in the hollow section 3 of the post 1, first of each locking element 7 outwardly projecting latching hooks 8, which are each provided with an insertion bevel 26 at the top, at the inlet into the hollow section 3 on the inner sides of the respective assigned Side walls 12 and 13 of the post 1 deflected so that when further pushing the respective projecting free end of each latching hook 8 runs along the inside of the associated side wall 12 and 13, with the result that the elastic locking element 7 something in the direction of the Inside the hollow section 3 of the post 1 is deflected resiliently.

As soon as the plug-on part 5, however, has reached its insertion end position, the latching hooks 8 of the latching elements 7 reach the hole 11 provided for each of them, in which they then engage automatically on insertion due to the elastic deflection of the latching elements 7.

This condition is in Fig. 5 shown.

From the above it can be seen that the attachment of the upper portion of the post connector 4, namely the Aufsteckteils 5, at the lower end of the post 1 only by the insertion of the Aufsteckteiles 5 in the hollow section 3 of the post 1, wherein the attachment by the automatic engagement the locking elements 7 takes place with their latching hooks 8 in the correspondingly mounted in the side walls 12 and 13 of the post 1 holes 11. The use of any screws or screw-like elements for connecting the Aufsteckteiles 5 with the post 1 is completely eliminated, so that a particularly rapid attachment of posts 1 and 5 Aufsteckteil is obtained solely by the Aufsteckvorgang of the latter in the post 1.

In Fig. 6 is a section through a frame profile 2 shown, on the upper side of the lower base part 9 of a post connector 4 is mounted. Here, the base part shown here 9 of the post connector 4 carries an upwardly projecting mold projection 14, which enters in the mounted state of the overall arrangement in a formed in the hollow section 3 of the post 1 hollow chamber. Such an embodiment of the base part 9 of a post connector is in the German Patent application no. 10 2015 112 563.3 of July 30, 2015 described in detail, with reference to the embodiment described there is specifically referenced.

The base part 9 of the post connector 4 comprises, as Fig. 6 shows, a support plate 15 which is supported in the mounted on the frame profile 2 state against the top of the frame profile 2. From the support plate 15, the mold projection 14 protrudes upward, perpendicular to the plane of the support plate 15, upwards, being supported on both sides thereof by a reinforcing rib 16 or 17 extending over almost its entire height.

Like from the FIGS. 6 and 7 can be removed, the molding projection 14 in its thickened lower portion on both sides of an area parallel to each other (and directed transversely to the longitudinal direction of the profile frame 2) locking teeth 18.

Fig. 7 finally shows an enlarged sectional view according to cutting position CC Fig. 6 ,

How Fig. 7 shows are on the frame profile 2 facing bottom of the support plate 15 of the base member 9 downward resilient locking elements in the form of spring hooks 19 are attached, which are provided at their free projecting ends with radially outwardly directed latching hooks 20. The latching hooks 20 are arranged in mutually opposite directions, namely radially outward.

These spring hooks 19 engage through a correspondingly mounted in the wall of the frame section 2 opening 21 through, where they immediately below after passing through the opening 21 with its outwardly directed latching hook 20 the local opening edge of the opening 21 under the outside. It can, as in the illustration according to Fig. 7 However, only two such spring hooks 19 associated with the opening 21, it can around the circumference of the opening 21 around but also more than two, z. B. three or four, spring hooks 19 are arranged.

The length of the spring hooks 19 is just chosen so that rest in the mounted state of the latching hook 20 against the underside of the wall of the frame profile 2, in which the bore 21 is mounted, latching.

The base part 9 of the post connector 4 can on the top of the frame profile 2 with this over such a latching arrangement, as in Fig. 7 is shown to be connected and thereby represent a sufficiently strong latching connection. However, it goes without saying that several such locking arrangements can be attached to the support plate 15, so that they can be connected in the assembled state and at several points by latching with the frame section 2.

Again, eliminates the need for using screws to attach the base to the frame section 2. Rather, the attachment between the base part 9 and frame part 2 in turn can be brought about only by the impressions of attached to the base part 9, projecting locking elements in corresponding locking receptacles which are formed on the frame profile 2.

In the sectional view according to Fig. 7 (corresponding to the cutting position CC off Fig. 6 ), the shaping projection 14 is cut in the region of its two lateral reinforcing ribs 16, 17, wherein a plurality of locking teeth 18 are formed on each of these reinforcing ribs in their lower region on their outer side facing away from the other reinforcing rib.

Now, if the base part 9 of the post connector 4 is mounted on the upper side of the frame profile 2 and secured thereto by latching, and if the Aufsteckteil 5 of the post connector 4, as in Fig. 5 shown, inserted at the lower end of the post 1 in the hollow cross-section 3 and there is also secured by locking, then the post 1 is attached to the attached to him Aufsteckteil 5 on the base frame 2 attached to the base part 9 from above and pushed so far until the engaging on the side surfaces of the reinforcing ribs 16, 17 locking teeth 18 with correspondingly arranged locking counter teeth 22, which are suitably formed in the above the base plate 6 of the Aufsteckteiles 5 formed shapes, have entered into latching engagement, as shown in Fig. 8 is shown. In this case, the locking teeth 18 and the locking counter teeth 22 are formed so that they allow in the direction of Aufsteckbewegung of Aufsteckteiles 5 on the base part 9 relative movement of both parts to each other, although they are in the opposite direction, however, the desired locking connection is present and a relative movement the parts is prevented from each other in this direction.

How out Fig. 8 can also be removed, protrude from the support plate 15 of the base member 9 vertically upwards elastic support members 23 which are integrally formed with the support plate 15 and inserted into corresponding receiving openings 24 in the plug-5. These support members 23 reinforce in this inserted position, the total rigidity of the Aufsteckteiles 5 in the areas where locking engagements are formed, in such a way that the interlocking elements with each other can not perform a catching action canceling relative movement.

Thus arises also in this juxtaposition of Aufsteckteil 5 and base part 9 (each with attached thereto posts 1 and 2 frame profile) turn that alone by the Aufschiebevorgang the two parts of the post connector 4 with each other in latching engagement and, again without any screw connection, are secured together by latching only.

Thus, an arrangement is created in which all fastenings of the individual assembly parts (post 1, frame section 2, plug-on part 5 and base part 9) are fastened to each other screwless alone by snap-in connections, which is triggered by appropriate pushing together of the parts and thus a particularly rapid assembly of to reach the entire arrangement.

In an unclaimed connection arrangement, however, it is also possible, during assembly, the two parts of the post connector 4 not by a mutual locking, but z. B. by a pin bolt (not shown in the figures) to connect with each other, which is inserted through a passing through the structures of both parts of the post connector 4 receiving bore and thereby defines both parts together. However, the case, the Aufsteckteil 5 and the base part 9 also to be fastened by a latching connection to each other, in most cases preferable, especially as this assembly of the overall arrangement can take place a little faster.
