Abstract
In a mounting fixture with an opening (10) to non-rotationally receiving a square pin or spear (11) mounted on a roller and with a slot (9) permitting the insertion of the pin and extending from an edge (1) to said opening (10), there is provided a resilient tongue (13) forming a bottom in said slot and acting in its normal position as a block to the pin (11) in the opening (10), said tongue when subjected to resilient bending away from its normal position allowing the pin to pass through the slot (9). <IMAGE>
Description
SPECIFICATION
A mounting fixture for rollers of blinds and
the like 'The invention relates to a mounting fixture for
rollers of blinds and the like, which in a
known manner consists of a moulded body of
a slightly elastic plastic material and compris
ing an opening to non-rotationally receiving a
square pin or spear of the roller, and a slot
extending from the edge of the body to said
opening and permitting the pin to be inserted
therein.
In Germany such mounting fixtures have
been developed which are in particular in
tended to be used in connection with inclined
overhead windows and are adapted to be
screwed on the inner face of the sidepieces of
the window frame at its upper corners so as to
fit closely to the top piece of the frame.
According to circumstances, the fixtures may,
however, also be mounted in another way, for
instance on lining panels of the window.
The pin receiving opening of this known
fixture and the slot leading thereto have in
principle the same design as in traditional
roller blind mounting brackets made from
metal sheet by a stamping or punching opera
tion and form together an angular track,
which at the transition point between the
inner end of the slot and the opening presents
a cam or projection to prevent the square pin
from jumping out of the opening.
The purpose of the invention is to provide
better security in this respect without compli
cating the design of the fixture or increasing
its cost of production.
Accordingly, the mounting fixture of the
invention is characterised in that the body
comprises a resilient tongue associated with
the slot and which in its normal position
blocks the opening in the direction towards
the slot but, upon insertion of the pin in the
direction towards the opening, is resiliently
bent into a position in which the blocking
effect is eliminated.
The resilient tongue of the fixture so de
signed fully ensures that the square pin will
not unintentionally leave the opening, as this would require a bending of the tongue away
from its blocking position, which cannot be
effected by a casual influence. The improved
security may be particularly important if the
fixture is mounted on the sash of a tilting
window instead of on the stationary casing,
because the tongue will then, even when the
sash is tilted into its cleaning position, prevent
the square pin from dropping out of the
opening and further out through the slot.
When the mounting fixture is of the type
referred to above, in which the slot together
with the opening constitute an angular track,
the resilient tongue may appropriately form a
bottom solely in the part of the track that corresponds to the slot and may in its normal position with its free end block the opening.
In this case the tongue is usually not affected by the square pin resting in the opening, and it remains so entirely uninfluenced in the blocking position.
This embodiment of the mounting fixture according to the invention will now be more fully explained with reference to the drawing, in which
Figure 1 shows the mounting fixture in front view, and
Figure 2 is a section along the line ll-ll in
Fig. 1.
In the shown embodiment the fixture is trapezoidal with parallel front and rear edges 1 and 2 and a bottom edge 3 perpendicular thereto, and an inclined top edge 4. The back 5, Fig. 2, is, moreover, somewhat bevelled in relation to the front 6.
The fixture is moulded to form a one piece body consisting of a slightly resilient material, such as nylon. The front 6 is integral with a pair of projections 7 with countersunk holes 8 for screws of mounting, and between said projections the front 6 comprises a rather wide slot 9 extending from the front edge 1 and merging at its interior end into a laterally directed opening 10 for a square pin or spear 11 on a roller blind. Said pin is in both figures indicated in dotted lines.
At the front edge 1 the fixture comprises a bridge portion 12 forming a bottom of the outermost part of the slot 9, and which at its upper edge, as illustrated in the drawing, is integral with the rod of a tongue 13 that, when unloaded, slopes towards the front 6 and forms the bottom of the remaining part of the slot of insertion 9.
When the square pin 11 is inserted into said slot, i.e. upwards on the drawing, its end surface abuts the tongue 13 and bends it backwards so that the pin may be passed to the inner end of the slot and then laterally into the opening 10 so as to let off the tongue 13 which will then return to the position shown in Fig. 2, in which its free end effectively blocks the pin 11 lying in the opening 10.
1. A mounting fixture for rollers of blinds and the like, consisting of a moulded body of a slightly elastic plastic material and comprising an opening to non-rotationally receiving a square pin or spear of the roller, and a slot extending from the edge of the body to said opening and permitting the pin to be inserted therein, characterised in that the body comprises a resilient tongue associated with the slot and which in its normal position blocks the opening in the direction towards the slot but, upon insertion of the pin in the direction towards the opening, is resiliently bent into a position in which the blocking effect is elimi

Claims (4)
1. A mounting fixture for rollers of blinds and the like, consisting of a moulded body of a slightly elastic plastic material and comprising an opening to non-rotationally receiving a square pin or spear of the roller, and a slot extending from the edge of the body to said opening and permitting the pin to be inserted therein, characterised in that the body comprises a resilient tongue associated with the slot and which in its normal position blocks the opening in the direction towards the slot but, upon insertion of the pin in the direction towards the opening, is resiliently bent into a position in which the blocking effect is elimi nated.
2. A mounting fixture according to claim 1, and in which the slot together with the opening constitute an angular track, characterised in that the resilient tongue forms a bottom solely in the part of the track that corresponds to the slot and in its normal position with its free end blocks the opening.
3. A mounting fixture for rollers of blinds and the like, substantially as described with reference to the drawing and as illustrated therein.
4. A mounting fixture for a roller comprising a moulded body part of plastics material, having a cavity therein to receive, non-rotationally, a pin or spigot at the end of the roller, and a recessed track leading from the periphery of the body to the cavity, and enabling in sertion of the spigot, characterised in that the body has a resilient tongue which normally blocks exit from the cavity into the track, but is resiliently displaceable by a spigot which is being slid along the track, to a position freeing the cavity and enabling insertion of the spigot.
