This application claims benefit of Italian patent application number TO2006A000434, filed Jun. 15, 2006, which is herein incorporated by reference.
1. Field of the Invention
The present invention relates to accessories for door and window frames and it pertains to a method for mounting an auxiliary member on a door or window already installed.
2. Description of the Related Art
A door or window comprises a frame and a drive assembly constituted by the devices and components that enable to transmit the opening/closing motion from the handle to various closure elements. The devices and components of the drive assembly are mounted, regulated and fastened to the frame when installing the window or door.
In some cases, after the window or door is installed, it is necessary to add an auxiliary member to the window or door. For example, it can be necessary to add one or more additional closure members to enhance the security of the closure.
In prior art solutions, the addition of auxiliary members in a window or door already installed is a long and complex operation, that entails cutting one or more transmission rods to measure and forming holes on the rods for fastening the auxiliary members. These operations require equipment available in the workshops of the manufacturers but that is not easily transportable on the site where the window or door is installed.
The object of the present invention is to provide a method for mounting an auxiliary member on a window or door already installed, that is simple and does not require the use of special equipment.
According to the present invention, said object is achieved by a method having the characteristics set out in claim 1.
The present invention shall now be described in detail with reference to the accompanying drawings provided purely by way of non limiting example, in which:

With reference to
The drive assembly 22 comprises a plurality of actuating members 24, 25, 26, 27, 28, and a plurality of transmission rods 30, 32. The actuating members shown in
The actuating members 24, 25, 26, 27, 28 are mounted on the frame 10 as described in a contemporaneous patent application by the same applicant with the title: “A method for mounting a drive assembly for door and window frames”.
With reference to
The auxiliary member 130 is for example constituted by a closure member destined to co-operate with an abutment (not shown) fastened to the fixed frame of the window or door. The auxiliary member 130 is destined to be mounted on one of the transmission rod 30, 32.
As shown in
Each transmission rod 30, 32 comprises a central portion 34 and two lateral portions 36, 38 situated at opposite parts relative to the central portion 34. The two lateral portions 36, 38 have respective mutually co-planar bases 40, 42. The central portion 34 has a base 44 that is parallel and distanced from the bases 40, 42 of the lateral portions 36, 38. The base 44 of the central portion 34 is connected to the respective bases 40, 42 of the lateral portions 36, 38 by means of two longitudinal ribs 46. The base 44 of the central portion 34 and the ribs 46 form a “U” shaped longitudinal groove 48 that extends along the central portion 34 and that separates the two lateral portions 36, 38. The central portion 34 has two lateral extensions 50 and 60 that extend exteriorly beyond the ribs 46. The two bases 40, 42 of the lateral portions 36, 38 have at their outer ends respective longitudinal ribs 52, 54. The height of the rib 52 of the lateral portion 36 is about half the height of the ribs 46. The rib 54 of the lateral portion 38 ends at the same height as the base 44 of the central portion 34 and it has a laterally projecting edge 56.
The two lateral portions 36, 38 form respective channel-shaped guides 58, 61. Each of the two guides 58, 61 has an upper surface 62 and two lateral surfaces 64, 66. The central portion 34 has an upper surface 68 that is parallel to the upper surfaces 62 of the guides 58, 61. The lateral extensions 50, 60 of the central portion 34 have lower surfaces 70 inclined at an acute angle relative to the lateral surfaces 64 of the ribs 46. The thickness of the bases 40, 42 of the lateral portions 36, 38 of the ribs 46 and of the base 44 of the central portion 34 is substantially constant. The rods 30, 32 are preferably made of metallic material (e.g., aluminium alloy) or plastic material (e.g., polyamide).

With reference to
The coupling portion 72 of the auxiliary member 130 has a section 102 provided with a threaded through hole 104 with orthogonal axis relative to the inner surface 82 of the body 74. A screw 106 is engaged in the threaded hole 104. The screw 106 has a threaded body 108 and a tip 110 that projects from the threaded body 108. The tip 110 has a cylindrical lateral wall with a smaller diameter than the diameter of the threaded body 108. The tip ends with a flat wall orthogonal to the longitudinal axis of the screw.
The screw 106 has a hexagonal slot 112 and an arresting edge 114 at one end of the threaded body 108. The length of the threaded body 108 is substantially equal to the length of the threaded hole 104, so that when the screw 106 is completely screwed into the hole 104 the tip 110 projects from the lower surface 82 of the body 74.
With reference to
Hereafter, the sequence will be described for the mounting of the auxiliary member 130 starting from the configuration in which the actuating members 24, 25, 26, 27 and 28 are already mounted on the frame 10.
With reference to
To mount the auxiliary member 130, the screw 106 of the angled transmission element 26 (

After the shearing of the scrap 116, the coupling between the coupling portion 72 and the transmission rod 30, no longer takes place by friction but rather by pivot-hole coupling between the tip 110 of the screw 106 and the hole 118 created by effect of the shearing of the base 44. This enables to have a more secure fastening than in a friction coupling and enables to eliminate deformations of the transmission rod that could produce interference with the walls of the groove 18 of the frame 10 creating difficulties in the sliding of the rods or the actuating members and difficulties in operating the control assembly.
The fact of forming the hole in the rod 30 whilst the rod is in the final mounting position enables to avoid measuring, cutting and drilling the rod. The present invention therefore enables to mount auxiliary members on door and window frames already installed and with no need to use tools for cutting and drilling the rods, generally available only in the workshops of the manufacturers of the door and window frames.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
