Abstract

A device comprising a lifting rail that is firmly adhesively bonded to a pane is presented. The lifting rail has a tuning-fork-shaped vertical section that comprises an enclosing region having two mutually opposite open ends configured to bilaterally enclose an edge of the pane, and therefore fix the plane. The device also includes a stem surface, a region of bifurcation where the stem surface transitions into enclosing region, and an outer edge having a through-hole or a cutout. Also included is an adhesive strip that partially covers the stem surface in a manner that the through-hole or the cutout remain exposed. The adhesive strip also covers the enclosing region and the two mutually opposite open ends. The adhesive strip is deformed by the edge of the pane in two mutually opposite regions of the adhesive strip.

DETAILED DESCRIPTION OF THE FIGURES

FIGS. 1 and 1a

(15) FIG. 1 depicts the side view of a detail of a transparent pane 5 and a lifting rail 1 prior to joining in the direction R to form the device 1,5 of the prior art.

(16) Here, and in the following, the transparent pane 5 is a laminated safety glass pane (VSG).

(17) Here, and in the following, the lifting rail 1 is a component made of polypropylene having the length of 8 cm, the height of 6 cm, the thickness of 1 cm in the stem region 3, and the total thickness of 1.5 cm in the region 3.2 (cf. FIG. 1a) surrounding the edge of the transparent pane. The lifting rail 1 further has a region of bifurcation 3.1, where the region 3 transitions into the region 3.2.

(18) Centrally arranged in the stem region 3 is a circular through-hole with a diameter of 1.5 cm, which serves to accommodate a bolt for connection to a drive device, for example, a lifting device.

(19) FIG. 1a depicts the vertical section through the lifting rail 1 and thus illustrates its tuning-fork-shaped configuration.

(20) A polyurethane adhesive is filled into the interior of the region 3.2. Thus, the lifting rail 1 and the transparent pane 5 are ready for joining.

FIGS. 2 and 2a

(21) FIG. 2 depicts a side view of a joined device 1,5 of the prior art comprising a transparent pane 5 and a lifting rail 1.

(22) FIG. 2a depicts the vertical section through the device 1,5 of the prior art.

(23) By means of the insertion of the transparent pane 5 into the interior of the enclosing region 3.2, the uncured adhesive 4 is displaced and distributed on the bonding surface. However, in this process, the uncured adhesive 4 is also squeezed out laterally from the region 3.2 and thus forms the undesirable pressed-out adhesive masses 4.1.

FIGS. 3 and 3a

(24) FIG. 3 depicts a side view of the transparent pane 5 and of the lifting rail 1 prior to joining in the direction R, R1 to form the device 1,5 according to the invention.

(25) FIG. 3a depicts the plan view of the lateral vertical end edge of the lifting rail 1 to be used according to the invention.

(26) The lifting rail 1 to be used according to the invention has a circumferentially adhesively mounted adhesive strip 6 (Tesa Transparent Tape 57405 (glossy)). Here, the stem region 3 is covered such that the through-hole 2 remains exposed. The region of bifurcation 3.1 is completely taped over, whereas, in contrast, the enclosing region 3.2 is covered only to just below the upper edge 3.3.

(27) FIG. 3a depicts the manner in which the adhesive strip 6 bridges the opening in the lateral vertical end edge.

(28) The adhesive 4 (not visible) is situated in the interior of the enclosing region 3.2.

(29) Thus, the transparent pane and the lifting rail 1 with the adhesive strip 6 are ready for joining.

FIGS. 4 and 4a

(30) FIG. 4 depicts the side view of the joined device 1,5 according to the invention with the two regions 6.1 of the adhesive strip 6 deformed by the edge of the transparent pane 5. This configuration is illustrated again by FIG. 4a, which offers a view of the lateral vertical end edges of the device 1, 5 according to the invention.

FIGS. 5 and 5a

(31) FIG. 5 depicts a side view of a lifting rail 1, as it can be used in the method according to the invention for producing the device 1,5 according to the invention.

(32) FIG. 5 a depicts the vertical section through the lifting rail 1 of FIG. 5 along the section line A-B.

(33) The lifting rail 1 of FIG. 5 corresponded in its features to the lifting rail 1 of FIG. 1, with the substantial difference that instead of the through-hole 2 in the stem surface 3, the outer edge 3.4 had the cutout 7. The connection to a drive device, for example, a lifting device, was able to engage in this cutout 7.

FIGS. 6 and 6a

(34) FIG. 6 depicts a side view of a lifting rail 1, as it can be used in the method according to the invention for producing the device 1,5 according to the invention.

(35) FIG. 6 a depicts the vertical section through the lifting rail 1 of FIG. 6.

(36) The lifting rail 1 of the FIG. 6 corresponded in its features to the lifting rail 1 of FIG. 1, with the substantial difference that its stem surface 3 and the enclosing region 3.2 formed a planar surface. This is illustrated again by FIG. 6a, which shows that the vertical section does not have a tuning-fork-shaped configuration.
