Description

[0001] The invention relates to a mounting device for the installation of an external window sill.

[0002] Exterior window sills, which are usually made of aluminum sheet and are located on the outside of buildings, are typically installed with a predetermined, outward-sloping incline to ensure rainwater drainage. During installation, exterior window sills are applied by applying mounting foam or adhesive between the underside of the window sill and the substructure. Once cured, this adhesive creates a firm, insulated connection. However, since the mounting foam expands during curing, the exterior window sill must be secured before the mounting foam hardens, for example, using wedges or supports attached to the sides, to prevent the exterior window sill from lifting and to maintain the required incline. Such prior fixing, however, requires a correspondingly high level of installation effort.

[0003] AT 004 959 U1 discloses a device for attaching an exterior window sill to a window frame. This device comprises a connecting profile that can be attached to a window base profile by means of screws, with a rear contact surface for contact with the outside of the window frame. The connecting profile comprises a web and two legs projecting from it, between which the exterior window sill is held. The web has a sealing lip at its upwardly projecting end to seal the connection between the web and the adjacent window base profile. The connecting profile serves as a permanent fixture and remains on the window frame after the window sill has been installed.

[0004] DE 92 08 104 U1 discloses a device for installing a window sill on the lower crosspiece of a window frame fixed to the building. This device comprises several angled retaining parts that can be attached to the crosspiece by means of screws. These retaining parts comprise a first leg provided with holes for contact and attachment to the window frame, and a second leg for supporting the window sill. These retaining parts also remain on the window frame during installation of the window sill and cannot be reused for subsequent installation.

[0005] The object of the invention is to create a mounting device serving as a reusable mounting aid which enables simple yet precise mounting of an external window sill.

[0006] This object is achieved by a mounting device having the features of claim 1. Expedient embodiments and advantageous further developments of the invention are specified in the subclaims.

[0007] The mounting device according to the invention contains a support body having a rear contact surface for contacting an outer side of a window frame, a lower contact surface inclined at a predetermined angle α relative to the rear contact surface for contacting an upper side of the outer window sill, and a retaining element arranged as a projection on a rear extension of the support body for positively and / or non-positively holding the support body on the window frame. Due to the positively and / or non-positively holding the support body on the window frame with the defined contact on the outer side of the window frame and the predetermined inclination of the lower contact surface, the support body can serve as a defined and stable contact for the outer window sill.The stable lower contact surface of the support body, which is precisely positioned at the desired angle of inclination, prevents the exterior window sill from lifting due to the curing of the assembly foam, even without wedges or additional supports. The assembly foam, which is inserted beneath the exterior window sill for installation and expands during curing, presses the upper side of the forward-leaning cover of the exterior window sill against the lower contact surface of the support body, which is firmly supported on the window frame, thus ensuring the exterior window sill is precisely aligned with the desired angle. Using the retaining element, the support body can be easily clamped to the window frame and, after installation, can be removed particularly quickly and easily.

[0008] In a particularly practical embodiment, the retaining element can be designed for positive engagement with a corresponding counter-element on the window frame. The positive engagement of the retaining element with the corresponding counter-element on the window frame can be used to simply yet effectively prevent the support body from shifting and the lower contact surface from being lifted.

[0009] The holding element can, for example, be designed as a web-shaped nose for positive engagement in a groove-shaped counter-element on the underside of a ledge at the lower end of the window frame. To ensure good retention, the holding element designed as a web-shaped nose can preferably have a slightly smaller width than the groove-shaped counter-element on the window frame. This allows the support body to be held particularly securely to the window frame. However, a clamping hold of the support body on the window frame can also be achieved in other ways. For example, the rear attachment of the support body which engages under a ledge of the window frame can be made of an elastic material so that a clamping hold is enabled by deformation of the ledge during assembly.In addition, the projection engaging the window frame could be coated with a friction-increasing material or made of a high-friction material to prevent undesired displacement of the support body.

[0010] In a simple manufacturing design, the support body can be L-shaped, for example, and contain an upwardly projecting support leg with the rear contact surface and a forwardly projecting support leg with the lower contact surface. However, the support body can also have a triangular shape or another suitable basic shape with the correspondingly aligned support and contact surfaces.

[0011] The lower contact surface of the support body is preferably inclined at an angle α of 95° relative to the rear contact surface. The cover of the exterior window sill, which rests against the lower contact surface during installation, thus has a downward slope of 5°.

[0012] The support body may conveniently be made of plastic or another suitable material.

[0013] Further features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings. They show: Figure 1 a mounting device in a perspective view and Figure 2 which in Figure 1 shown mounting device in an assembly position.

[0014] In Figure 1 A mounting device 1 for mounting an exterior window sill 2 is shown in a side view. The exterior window sill 2, which is usually made of aluminum sheet, has, in a conventional manner, a rear bevel 3 for attachment to a window frame 4 and a downwardly inclined cover 5 for covering a wall or facade recess.

[0015] The Figure 2The mounting device 1 shown in a perspective view contains a support body 6 which is L-shaped here and which has an upwardly projecting support leg 7 with a rear contact surface 8 for contact with an outer side 9 of the window frame 4, a forwardly projecting contact leg 10 with a lower contact surface 11 inclined at a predetermined angle α with respect to the rear contact surface 8 for contact with an upper side 12 of the cover 5 of the outer window sill 2 and a holding element 13 for clamping the support body 6 to the window frame 4.

[0016] In the embodiment shown, the holding element 13 is designed as an upwardly projecting nose on a rear projection 14 of the support body 6 for positive engagement in a Figure 1shown groove-shaped counter element 15 is formed on the window frame 4. The groove-shaped counter element 15 is formed on the underside of a shoulder 16 at the lower end of the window frame. The retaining element 13, designed as an upwardly projecting, web-shaped nose, has a slightly smaller width than the groove-shaped counter element 15 on the window frame. The lower contact surface 11 is inclined at an angle α of between 92° and 97° relative to the rear contact surface 8. The angle α is preferably 95°, so that the cover 5 of the outer window sill, which rests against the lower contact surface during assembly, has a downward inclination of 5°.

[0017] To mount an external window sill 2 using the mounting device described above, the external window sill 2 can be mounted according to Figure 1First, it is placed on a wall or facade ledge below the window frame 4 and then secured to the lower end of the window frame via the bevel 5 using screws or other suitable fastening elements. Depending on the length of the outer window sill 2, two or more of the mounting elements 1 can then be arranged with their lower contact surface 11 in a direction opposite to the Figure 1 shown position turned position on the outside window sill 2 and then according to Figure 1be rotated so that the rear attachment 14 of the support body 6 comes under the shoulder 16 and the nose-shaped holding element 13 comes into positive engagement with the groove 15 on the underside of the window frame 4. By the engagement of the nose-shaped holding element 13 in the groove 15 of the window frame 4, the support body 6 is held with its contact surface 8 on the outer side 9 of the window frame 4 and a lifting of the forward-projecting contact leg 10 is avoided. The cavity located under the outer window sill 2 can then be filled with assembly foam. When the assembly foam expands during curing, the outer window sill 2 is pressed with the upper side 12 of the forward-projecting cover 5 against the lower contact surface 11 of the stably held support body 6 and thus has the desired orientation after the assembly foam has cured.
