Abstract
A frame assembly for a window or door comprises a frame member having apertures 18 providing for ventilation and a control member 20 moveable relatively to the frame member for blocking and uncovering the apertures 18. The control member 20 has a flock coated surface which contacts the frame member to form a relatively draught free seal. <IMAGE>
Description
SPECIFICATION
Window or door frame member
This invention relates to a frame member for a window or door. The invention has been developed in relation to a frame member of extruded aluminium alloy for use in the manufacture or installation of double glazed windows or doors.
Security requires that windows or doors are closed at night or when the premises in which they are installed are unoccupied. However, there may be a requirement for ventilation under such conditions, which requirement has been met hitherto by designing frame members to provide for flow of air from one side of the window or door to the other side thereof. It is desirable that there is some provision for preventing such flow of air when it is not required, and this can be difficult to achieve in extruded sections of relatively substantial length since a slight bias along the length of extrusion may occur during manufacture and accordingly prevents draught free closure of the frame member.
According to the present invention, we provide an assembly comprising a frame member for a window or door, defining, or adapted to define in combination with a surrounding structure in which it is to be installed, a passage for flow of air between opposite sides of the window or door and including a wall portion with at least one aperture for said air flow, and a control member movable relatively to the frame member between positions in which it blocks and uncovers said at least one aperture, said control member having a surface which contacts said wall portion at least when it is in its blocking position and which carries a resilient coating to take up any tolerances between the control member and frame member to form a relatively draught free seal therebetween.
Preferably the resilient coating is a flock coating, i.e., a coating of short fibres adhesively secured to the surface of the control member.
Preferably the frame member and control member have complementary longitudinally extending formations which mount the control member for sliding movement longitudinally of the frame member. The frame member and control member may each then be provided with a plurality of apertures spaced uniformly therealong.
The control member may be an extrusion of a plastics material.
The invention will now be described by way of example with reference to the accompanying drawings, of which
Figure 1 is a perspective view of part of an assembly embodying the invention
Figure 2 is a transverse cross-section through another embodiment of assembly according to the invention.
Referring firstly to Figure 1, the assembly there illustrated comprises a frame member 10 which is an aluminium alloy extrusion and which in the particular example illustrated is intended to form the upper fixed horizontally extending part of a sliding patio door assembly. Thus the frame member 10 comprises an exterior vertically extending portion 11, an interior vertically extending portion 12, and an intermediate vertically extending portion 13, joined by horizontal webs 14, 15. The doors would be accommodated in the downwardly opening channels defined between the portions 11 and 13, and 12 and 13 respectively. Above the webs 14, 15 the frame member has formations 16 which enable the securing together of the frame member illustrated and other appropriately sectioned members to form the entire fixed frame of a patio door assembly.
The uppermost parts of the portions 11, 12 of the frame member are provided with uniformly longitudinally spaced apertures 17, 18, respectively. These provide for passage of ventilation air, as indicated by arrows 19 or in the reverse direction, between the interior and exterior of the building structure in which the patio door assembly is installed. It will be appreciated that in such an installation the top of the frame member is closed by the structure in which it is installed, and that the formations 16 do not extend sufficiently far upwardly to obstruct the air flow between the interior and exterior of the frame member.
For blocking the apertures 18 when ventilation air flow is not required, a control member 20 having longitudinally spaced apertures 21 corresponding to the spacing of apertures 18 is mounted on the portion 12 of the frame member for sliding movement longitudinally thereof as indicated by arrows 22. In section, the control member 20 comprises a surface 23 which lies in face to face contact with the wall portion of the frame member in which apertures 18 are formed, and above the surface 23 a part defining a groove 24 in which fits a projection 25 from the frame member. Below the surface 23, the control member 20 has a projection 26 which fits in a groove 27 in the frame member, so that the control member is mounted for its sliding movement. A further part 28 extending from the control member provides a manually graspable handle for moving the control member.
The surface 23 of the control member has a flock coating, i.e. an adhesively secured coating of short fibres. This is effective to take up any tolerances between the control member and the frame member to form a relatively draught free seal when the control member has been moved to block the apertures 18 when ventilation is not required. In addition, the flock coating tends to prevent possible rattling of the control member against the frame member which might be a problem in certain wind conditions, and provides a degree of friction to its sliding movement so that it remains in the position it is placed.
The control member 20 typically is an extrusion of a relatively rigid plastics material. The flock coating would be applied by a known technique, e.g. by rolling a suitable adhesive onto the surface of the extrusion required to be covered with flock and then the fibres would fall or be blown onto the adhesive to stick thereto. An electrostatic technique may be utilised to ensure that the fibres tend to stand on end in order to increase the effectiveness of their sealing action. The fibres may, for example, be of nylon, of one to two millimetres length.
Referring now to figure 2, there is illustrated an alternative form of frame member, 30. This has a rear wall 31 with spaced apertures in it to provide for ventilation air flow. The wall 31 is at the base of an undercut groove, and an elongated control member 32 is received therein, the control member having apertures in it corresponding to the apertures in wall 31 as above described. The surface of the control member which contacts the wall 31 carries a flock coating to assist its draught free sealing action when it is blocking the apertures in the frame member.
In the construction of Figure 1, the mode of engagement between the frame member and control member is such that the two can be fitted together without necessarily sliding the control member from an open end oftheframe member.
These two members can be snapped together laterally if necessary.
Claims (6)
1. An assembly comprising a frame member for a window or door, defining, or adapted to define in combination with a surrounding structure in which it is to be installed, a passage for flow of air between opposite sides of the window or door and including a wall portion with at least one aperture for said air flow, and a control member movable relatively to said frame member between positions in which it blocks and uncovers said at least one aperture, said control member having a surface which contacts said wall portion at least when it is blocking said at least one aperture and which carries a resilient coating to take up any tolerances between the control member and frame member to form a relatively draught free seal therebetween.
