Abstract

A B S T R A C T
SLIDING WINDOW comprises of upper immovable casement (3) , and lower movable casement (2). By means of the handle (4) and angle bars (?1) and (?5) which are installed on the support plates (28), the casement (2) is releaved to be lifted or dropped; to be axially moved for 8 mm, in regards to the frame 1, or to be open to "VENT" position.
The casement (21) may be lifted by means of tension spring (20) pulley block (25) and the weight (23), which are set up into the hollow on the frame 1.
By means of the gasket (12) and the groove (9) on the frame 1,, the window may be sealed. There are hollows (15) and notches (16) arranged along the opposite sides of the gasket body (12). On the angled part of the gasket (12) there are elastic angled parts (13), which rest on the angled groove (8) surface which is set up on the casement 2.
There is a rubber gasket (11) fitted into the groove (2b) on the bottom casement 2. The A/M gasket strikes projecting part of the bent metal sheet (10), which is fixed to the inclined frame surface (1).
Instead of using gasket (12) squared gasket (17) with the elastic angled attachements (18) which is installed into the angled aoutlet (1b), beneath the groove 2c, on the bottom casement 2, can be used.

Description

2Q32~26 SLIDING WIMDC~

This particular invention contained in this patent application, belongs to the cor,struction i~dustry.
It may be manufactured of wcod, pla~tics, or metal, in the factories in which ordinary windows are made without new lnvestemnts ln the equipment.

- The essence of this invention is as followst window casement moves vertically in order to open and cl~se the windc~, and does not come inside the room, i.e. the room space is not being reduced.
Since the casement may be axially moved in relation to the windcw frame, fresh air penetration may be regulated by the handle position.
When the handle is in position I, the window is completely closed and the outside air can not penetrate into the room. When the handle is moved for 45 fowards to the position Il, the casement is axially opened 8 mm in relation to th~ frame.
There is a special gasket, which enables the air to penetrate into the room, while the water drips down through the tube gasket and goes out. When the handle is in the position II, the casement moves up and down and remains in each position.
If you have to wash the botto~ casement, the handle is moved into ~he position III, and the casement around t~e horizontal axis is opene to vent position, and therefore you may wash the windG~ fro~
the inside.

m e advantages of the sliding window are as follows.

a) TCrAL SEA~ING
b) Possible ventilation regulation c) Ewal ~ oliftpafnet~lensCta~el ~ 7t/although it has thermo - insulating ... . , . . . . _ 2~32826 d) possibility to wash the windcw from the inside.
e) On opening the window, the casement does not get into the room;
- it has a simple desing, - angle bars, window-panes and lumber are unified9 Production technology is easy one.

The above mentioned ch~racteristics make the sliding window, advanced generation product.

Currently, there are three different types of windows used:

- Construction "NARRoW aox"
'- Construction " CESEMENT T~ CASEMENT"
- Construction "SINGLE WINDoW"

Main common characteristics of the A/M windowsare:

- The casement is being open along the vertical axis as well as along the horizontal axis if the window is open to the "VENT"
position.
- When the window is open, the casement "COMES" inside the room, and therefore the roc~ space is being reduced.
- The casement position can not be fixed and, therefore the air current may change the casement position (which means that the window may be suddenly closed and cause the window breakage).
- In case when there is no one in the room for a longer period of time, the windows have to be closed.
- In closed position on the A/M windcws, there is a gap between the casement and windcw-pane through which the fresh air fluws fram the outside.
Depending on the air-flow rate within certain time unit along the 1 m of gap, these windo~s can be divided into 4 groupso A,B,C,D.
According to the obtained values, the capacity of heating bodies depend.

2~32~26 Depending on wood ~uality, gaskets or angle-bars design , air volume is being changed by the outside climate influences, such as: building location, blust exposure, height of building, All these circumstances determine roon heating.

- For each window dimension, there must be suitable angle-bar installed, -- Lumber, as the main raw material, have to be of a certain quality, because the large dimensions of the window may cause the frame deterioration~
- Since there are different window dimensions, with different casement profiles, which determinate Win~ow-pane dimensions, thermo-insulating par-t can not be produced in advance, since there is no standard dimension.

- Sliding Window covered by this invention, is shcwn on the attached sketches which include 27 different pictures.

lhe main part of SLIDING WINDC~ design is frame 1, with two casements installed:
upper casement 3, as a fixed part, and lo~er casement 2, which can be freely moved in 3 different directions depending on 4 different positions which open/close/ the windcw.

Frame 1 - is installed together with casements 2 and 3 in a deter~ined place on the wall 44. ~esides, frame 1 has hollows in a vertical line.
Weights 23, are installed into the AtM hollows, which help the window to be lifted along the vertical plane and to eliminate the casement weight from both sides of the windowsSCasements are hung by the springs (20) on spheric elements 38, on metal angle bar (35) of the lower casement 2; After the weight 23 is installed , hollow spa~¢
is closed with an adequate cover (6) which stops the weight 23 to fall off; Therefore, cover 6 is used as a guide of the weight 23, on it s way up and down.

There are edge lettices /2A/ on the bottom casemRnt which fasten thermo-insulating pane on the window. Upper casement has got 3 edge lettices /3A/ to fasten thermo-insulatiQg pane 7A, too.

2~32~6 6.-m ere is an arc groove/8/on the bottom ~sement (2) into whichthe soft rubber seal part /12/ rests on closing the window.

Along the bottom cesenent sides 2, th~re is a Gountersunk notch in which metal angle-bars are fasten , such as: sliding rail (43), with gear transmission (41) ccunter sunk into the groove (40) which is placed on the casement (2) ;
Then upper angle-bar (31), which is set up on the supporting plate 28, and lower angle bar (35) which is set up on the supporting plate 2~ too.

There is a longitudal flute (1A) installed into the sliding window frame 1, through which a spheric element (3~), on lower angle bar moves up and down~ the A/M element is l;nked to the weight (23) via tension spring (20) and pulley block.

aranked handle 4 has got:
Different directions of motion, while the bottom casement 2 has 4 available motions depending on cranked handle movement. When the chranked handle 4 is moved for 45 from the closed position to upper position - bottom casement 2 moves axially away from the frame 1 for 6 mm. Releaving circled notch on semi-spherical gasket 12, is air penetration enabled water, because of sudden pressure drop, drips down the tube 14 on the gasket 12 and flows out via sheet metal (10).

The A/M function is very impartant for the room ventilation in case when one is away from home for longer period of time (eg.for holidays~.
The window which is left in the A/M position can not be opened from the outside, since there is gasket 12 which is clamped into the groove 9 on the fram.e 1.

2~3282~

If you move cranked handle 4 from its initial closed position, for 90~ upwards9 bottom case~ent 2 moves away from the fra~e 1 for 12 mm, detaching off gasket 12. This stops the casement to slide off,upwards, to open the wir~ow. It is easy to lift up the case~ent, i.e. it i5 not "heavy" since it could be belanced by the weight 23 and therefore it remains in any open-closed position.

If you move cranked handle 4 fro~ its initial - closed position for 180, upwards, bottom casement 2 is capable to open to "VENT"
positinn.
Edge-support 5 ur~bles casement to slip out.
This means that it is possible to wash the window pane 7 from the outside9 which was not the case with ordinary wind~ws, and therefore they had not been used in building construction before.

Before we go over with further explanation of metal angle-bar functions, we shall give some comments on sectinn "B" , of the bottom casement shown on pictures 7,8,9,10,11 and 12, which can be constructed in two possible ways. With the first construction form (pictures 7,8,9) the bottom casement 2 con~rises of arc groove 8, gasket 12 and squared groove 2 B with the gasket 11 inside, which leans on sheet metal 10.
Gasket 11 stops moisture and water to overrun sheet metal 10, either from the atmosphere or gasket tube 1'4.
With the second construction form of the bottom casement there is no arc groove 8, squared groove 2B gasket 11 and 12 not sheet metal 10.
Instead of the A/M parts, there is a prismatic groove 2C, while there is an outlet 1B on the frame 1.
You may regulate sealing or room ventialtion by pressing or releasing elastic arc installment 17 of rubber gasket 17. This has already been explained before.

2 0 3 2 8 2 ~

Metal angle-bars for the casement 2 comprise of adJusting rail (43), with circled gear-transmission (413 , which have one squared slot (42) to make cranked handle (4) installed. Besides, there is left and right upper (31) and dcwn (35) angle har. All these elements are installed into the casement itself.
Both anele-bars( 32) and (35) are mounted on the same supporting plates (28), which have slots (29) along the vertical axis on plate center.

Upper angle-bar (31) is linked to the support plate (28) via adjustablearbor (32); I-t coIprises of a slot (33), and a cylindric element (34) on free top.
Also, lower angle-bar (35) is linked to the support plate (2a) via adjustable arbor (36); it has got an angle slot (37), as well as cylindric element (38) with a coun-terbore for the tension spring (20).

It should be mentioned that upper angle-bar (31) and lower angle-bar may have another constructive form, which differs only in a way of shortemng slots (33) and (37) to half of lenght; This can be noticed on posistions (33) A and (37) A on pictures (23) and (24).

If you move cranked angles 4, gear transmission (41) is rotating, m~ving the adjustable rail (43) away; ad~ustable rail has metal rollers (39) on its ends, which slide form their initial cloæ
position to the final open position, through the slots (29), on the support plates (28); which are screwed to the casement (2) sides.
Metal rollers (39) slide through the slots (33)and(37ton the upper angle--bar (31), and angle-bar (35), which limit their motion.
Cylindric elements (34) and (38) on the upper and lower angle bars slide through the grocve 1A on the window frame 1.

2~3282~

The weight (23) is clasped by the other end of tension spring to the cylindric ele~ent (38) of the lower angle-bar (~5), via hook (243 and tension spring (20), which comprises of a loop (21), clamps (22) and pulley block (25). Pulley block (25) is installed into the carrier (27) via pulley axle, which is s~rewed to -the upper frame side (1). Such frame conDists of two weights (23), used for the left and right side to neutralize weight of casement (2).

If you move cranked handle (4) to the mld-position (90) in regards to the initial closed position, cylindric elements (34) and (3B) inside the goove 1A on the frame 1, move the casement (2) away from the frame for 15 mm enabling the casement to slide upwards, i.e it is possible to open the windcw.

If you move cranked handle 4 into its final open position which is 1~0 displaced in regards to its initial closed position, upper angle-bar (31) with cylindric element (34), come to the position on the frame 1, in which there is a slot made to enable cylindric element (34) to come out of the groove 1A. Lower angle-bar (35), remains in the same position, i.e. cylindric element (38) remaLns in groove lA, and enable casement (2) to be open to "VENT" position. In such position, the ouside window pane 7 may be washed from the room inside.

Metal angle-bar is very simple construction and of one unique dimension for each type of the window.
The window can be produced in all modules according to the construction standard.

Semi-spherical gasket12 is manufactured o~ dense rubber, while the tube 14 is used for water and moisture to be drained. Gask~t 12 have an elastic joint 13, made of sof~, sponge rubber used as a cover for circ~ed orifice (15) and (16).

O~ifice's (~15) and (ni6) a~ no-t sym~t~ically a~ang~'d flace -to fac~ ;
Orifices (115) are arraneed away from the gasket arc extention, while the orifeces ~K) are arranged closer to the are extention top~ Such arrangement enables room ventilation, wa-ter and condensated moisture draining, between the casement (2) and window frame (n1), if t~ windcw is in a semi-open possition.

If the bot~om casement (2) is performed in a different w~y, squared gasket (17) is used. On the upper side of the gasket (17), there are three are extentions (18), with the gaps (19) between them.
When you close the window , the extention 18, are leaning on the gaps (19). horizontally, forming a flat sealing surface.

Wind~w-panes (7) and (7A), have the unique dimensions, and therefore it is possible to manufacture the same, in advance for the storages and for the market too.
Lumber, as the main component, have'only one stanadard thickness (60 mm), which makes transport, storing, drying, and treatment in a tecbnological procedure easier.
