GB2397087A - Electrically operated window with automatically deployed net - Google Patents

Abstract

An electrically operated window may be controlled by a switch on the window frame, or may have remote control. A net 3A is attached to the upper sash 2D so that it automatically deploys when the sash is opened, to prevent foreign objects such as insects entering through the window. The window may also have light and rain sensors to operate the window automatically when rain is detected, or when the light is switched off in the room at night. The inner frame can also be pivoted about the upper edge 2M to provide an emergency fire escape route.

Description

239701 37 THE, AUTOMATIC AND MANUAL WINDOW TOTS INVENTION RELATES TO Tl IE

AUTOMATIC AND MANUAL WTN1)OW.

The window consists of an outer frame and an inner frame.

INSTALLATION.

The outer frame to be mounted first onto surrounding walls from the inside then fixed in by screws and sealed using sealant. The inner frame to be fitted from tile top by pushing the spring loaded bar, inwards fron1 either side so as to match the oblong holes on either side of the outer frame.

Door release anus to be fixed onto either sides of the outer frame. Finally the four fixing strips to be screwed into position.

F E A '1' tJ R. E S A N D (I H A R A C T E R I S T r s The automatic and manual window will be produced in three versions: 1. Else first version will be known as the 'budget class', which will involve the following features.

a. A switch to be mounted either on the frame or wherever the client requests it. ''I'lle switch will operate the motor within the inner frame, which in tun1 will move the upper window down/up.

b. When the upper window is moved down a net will be attached wretch will move down with the window as illustrated in figure 3. The net is incorporated to prevent foreign objects from coming inside. The net will be wound back up when the window is operated back up.

c. The fire escape facility will be incorporated whereby when there is a fire in the building this facility can be used to escape from the building.

N.B. Please note that this facility must only be used as a last resort, i. e. if there is no other means of escape.

2. The second version will be known as the 'standard class'. This will involve the following features: a. A net as described in (b) of the first version.

b. The fire escape facility as described in (c) of the first version.

c. rl his window will be of remote control operation, having three functions: (I) [Jp (11) DOWN (lTI) STOP d. Will have a rain sensor, mounted on the outside. This, when it rains, will automatically cause the upper window to move to the closed position.

e. Will have two light sensors fitted, one on the outside and one on the inside, so that if the customer should forget to close the window at night, then when the light is switched olf in the room the window will automatically move to tile close position *.

* If the client does not require this feature, then by using the remote control, can always operate the upper window back down.

f. Will 1lave an orange LED and a green LED, for power and motor run indication.

3. The third version will be letdown as the 'Upper Class' and will involve the following features: a. A net as described in (b) of the first version.

b. The tire escape facility as described in (c) of the first version.

c. The remote Control facility as described in (c) of the second version.

d. The rain sensor as described in (d) of the second version.

e. The two light sensors as described in (e) of the second version.

f. Will have a blue and white I,F'D as power and motor run indication.

g. Will have photo electric cells mounted on the inside, about half way down the upper and lower window, transmitters on the right and receivers on the left or visa versa, so that if broken into by a burglar the beams ol tile PEC's will be broken thus setting off tl1c alarm.

N.B l his feature will be an accessory, for if an alarm is fitted in the iuildmg.

h. Will have a temperature sensor fitted on the outside with a display / sensor on the inside to show the temperature for outside and inside.

i. A power divert switch for winter heater *.

* For future reference.

OPERATION

THE MECHANICAL OPERATION: The mechanical operation should be self:explanatory by looking at the diagrams. Where moving parts are involved, this concerns the upper window.

The lower window is fixed on the inner side. The upper window is moving up and down on the outer side. The bar mounted at the bottom is fixed at either end of the inner frame, is able to spin so that the rope can be wound up and down. The left and right hand door release arms will pivot up and down and be fixed to the inner frame. Also will move up and down on the track of the outer frame.

The upper window will consist of side sections with four wheels on each corner to ensure smooth operation. 'I'he wheels Will run up and down in a groove on either side Lo keep the upper window in a straight line. The 'bungee' or spring cord will be connected to the bottom part of the frame, and run over the top part of the inner frame to be collected to the bottom side of the tipper window as described in figure 2.c. '['he cord will act as a counter-balance and the tension will be adjusted so that when the motor is detached the upper window can run freely back to the upper or closed E,osition.

The motor will be fitted on a detachable mechanism whereby in the event of motor failure, or no power, the motor can be detached then the window can be moved manually to the closed position, and then the motor mechanism can be attached again. The motor pulley, when attached, will be engaged in the slots running along the side section to drive the window up alla down. This method is chosen because when the motor pulley is engaged and the motor is not running the window can not he moved up or down thus when in the closed position can stay locked.

A net will be fitted, attached to the top part of the upper window, along the top part of the inner frame, which will be rolled up when the window is in the chased position and rolled down when in the open position.

THE FIRE ESCAPE, FACILITY: Normally, the inner window *came will be locked into the outer frame when closed. As described in figure 5, two keys must be supplied with the lock separate to each other, i.e. the keys must not be together. The keys must be hung separately at two points on the window above the reach of small children. The keys must be hung separately so if one is misplaced the other is still available.

In the event of a fire in the building and there is no other means of escape, then the window can be used. By using one of the keys unlock the inner window frame, then push the window open. By doing this the side door release anus should drop. Tllen the rope beneath the window frame can be pulled down. Tile door release arms can be used to escape and the rope to climb down.

N.I]. 'I'he rope facility is not needed for windows fitted at ground level.

TECHN ICAL: The electronics will involve a basic circuit as described in the circuit/block diagram - figure 6. The power supply unit wild be in the form of an adapter. The power supply will be between 1 2-24V D.C. (2. 5 amp). The principle operation will be based on a 'normally open' circuit, whereby if any part of the circuit is closed i.e. rain sensor, light sensor, remote control function, a single or pulsed input is required to trigger the relay which will turn the motor. This is a 'kick- start' operation and once the motor is turning the motion sensor will take over. l'he motion sensor works by picking up movement from a small magnet fitted on the motor pulley thus sending a signa] to the I.C. via the amp, whicl1 in turn provides continuous input to the motor via the relay. Once the upper window reaches either end the motor stops turning thus no signal is sent to the l.C. meaning the motor stops turning. * * All the mechanical and electronic parts will be incorporated within the inner frame with easy access available.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows the outer frame of the automatic and manual window.

Figure 2 shows the inner frame of the automatic and manual window.

Figure 3 shows the inner frame with the upper window in the downward position (75 /0).

Figure 4 shows the position of the complete window for the fire escape facility.

Figure 5 shows how the complete window is to be locked.

Figure 6 shows the basic operation of the circuit / block diagram.
