Definitions
- the normal up-and-over door adopted to close a garage includes a mobile part that is a door and a fixed frame. When suspended, the door is balanced and has rods provided with end hinges where the top rods are hinged at the top of the fixed frame pillars.
- the lifting pins that are integral to the door slide in the grooved rails of the frame side pillars while the rods connecting the door to the frame force the door to tilt more and more in respect of the pillars while going up so that the top part of the door, above the pins, folds inside the garage and the bottom part, below the pins, protrudes otwards.
- the door When fully opened, the door reaches the top of the hole and,its position is nearly completely horizontal and transversal to the frame pillars.
- Another problem to overcome, common to all existing systems, is a rather laborious installation and difficult replacement.
- a further problem in the seals of known systems is that, due to the scraping of the moving parts against the fixed parts, the seal integrity is jeopardized because of wear and tear.
- a further disadvantage of the sealing system actually on the market is that, due to its necessarily rather rigid configuration when the door is closed, (caused by the closeness of the fixed part to the moving part) it does not always fill the gap required for the door to move or the gap caused by the door being out of squareness.
- the aim to be achieved is for them to guarantee sealing during the door movement without creating unacceptable friction in respect of the stress limits demanded by market requirements that cannot be exceeded by the door, as explained above when the example of the stress limits due to an obstacle encountered while moving was mentioned.
- a further aim for this patent is to create a sealing system that is as tight as possible so that the amount of water, air and light getting through is minimized.
- Another aim of this patent is for the sealing system not to create such friction during the door movement as to exceed the limit values demanded by market requirements should the door meet an obstacle.
- a further aim for this patent is that the sealing system must be structured in such a way that the scraping between the moving and fixed seals should ensure a satisfactory life span.
- the patented sealing system accomplishing all of the above aims and offering all the above-mentioned advantages is made up of two seals, one applied to the frame pillar and another one to the door adjoining side edge as described underneath.
- a resinous seal is applied on a grooved seat on each frame pillar, that includes: a semi-rigid attachment that, in continuity with a semi-rigid structure that expands in the gap outwardly towards the door, supports a flexible elastically yielding tubular configuration that is suitable to enter the practically-configured C-shaped seat of the adjoining door seal.
- the attachment that is inserted into the pillar grooved seat has a tubular quadrangular shape that matches the seat cavity it has to anchor to, its sides being provided with a series of tilted vertical tabs in the shape of saw teeth.
- the walls of the pillar grooved seats are appropriately knurled.
- the semi-rigid external structure in direct continuity with the attachment consists of a tubular, almost cylindrical element that is reinforced on the door interior side by an atypical semi-rigid tubular quadrangular configuration that goes from the side almost to the most external central part and that supports an overhanging pronounced semi-rigid wing on the external side.
- a thin film of fretting-proof material with anti-friction properties is coextruded on the most external part of said flexible element.
- the tubular almost cylindrical configuration in direct continuity with the attachment is realized this way as a prearrangement for possible infrared rays that, following the deformation of the tubular section due to anomalous stress may act as a safety device and block the movement of the door.
- a resinous seal is applied on each side pillar of the door that, seen from the front-end, has a rigid flat laminar base provided with V-shaped appendages on its back so that it can be fitted into the pillar dovetail grooved seat and provided, on its front, in correspondence with the side towards the door external surface, with semi-rigid tubular vertical ribbing and on its opposite side with a flexible eleastically yielding wing with a thin-walled elastically yielding curvilinear configuration tilted towards the internal flat laminar base.
- the purpose of the semi-rigid tubular vertical ribbing is to reduce friction when this ribbing rubs against the opposite seal during the door movement.
- This seal is to allow an element of the frame adjoining seal to be inserted in order to obtain a tight fit.
- the semi-rigid ribbing of the door seal is free and moves towards the outside, while the sliding and overtaking is taken over by the opposing flexible wing of the door seal.
- the door seals above the lifting holes overtake and cross over each other at an angle that goes from 0 to 90 degrees and scrape and slide on each other.
- the seal is provided with a very thin film of anti-friction and wear-resistant material.
- the surface of the film is provided with tiny noise-absorbing papillae.
- a third seal is fitted on the pillar, whose purpose is not tightness and that, located on the inside of the door closing hole, is used to reduce accessibility to the gap created between the frame pillar and the door pillar when the door is closed, and to shield the area where the pin supporting the door during its movement on the rail is located.
- Figure 1 is a top transversal view of just one side of the vertical structure of an up-and-over door consisting of the fixed frame pillar and the door pillar, both fitted with the seals that are the subject of this patent that seal the gap between the frame and the door.
- Figure 2 is like Figure 1 but one seal is added to the strengthening protrusion on the fixed frame pillar that is farther away from the external wall. This seal has the function to limit the access to the empty space between the fixed frame and the moving door and to shield the area of the grooved rail where the door suspending pin is when the door moves.
- Figure 3 is the axonometric projection from the outside and from the top of Figure 1.
- Figure 4 is the axonometric projection from the inside and from the top of Figure 1.
- Figure 5 is the axonometric projection, in isolation, from the top of the seal that is to be applied to the grooved seats present on the sides of the door side pillars.
- Figure 6 is the axonometric projection, in isolation, of the seal that is to be applied to the grooved seeats present on the internal sides of the fixed frame pillars.
- Figure 7 is the axonometric projection, in isolation, of the seals in Figures 5 and 6 when they engage each other during the door movement.
- Figure 8 is the axonometric projection, in isolation, like Figure 7, of the seals shown in Figures 5 and 6 in a different position of engagement.
- Figure 9 is a side stylized drawing of an up-and-over door where the door is nearly closed (or just opening).
- Figure 10 is a side stylized drawing of the same up-and-over door as in Figure 9, where the door is half-way between total closure and total opening.
- Figure 11 is a top transversal view of just one side of the vertical structure of an up-and-over door consisting of a fixed frame pillar and of the up-and-over door pillar showing, in respect of Figure 1, an enlargement of the seals that are the subject of this patent.
- Figures 12, 13, 14 and 15 show the succession of different engagement positions of the two seals in the pillar and in the door in respect of the part of door that is above its supporting pin during the opening (and closing) of the door.
- Figures 16, 17, 18, and 19 show the succession of different engagement positions of the two seals in the pillar and in the door in respect of the part of door that is below its supporting pin during the opening (and closing) of the door.
- Seal 3 is fitted onto the grooved seat of pillar 1 in the fixed frame and its outside part extends and fills the gap between pillar 1 in the frame and pillar 2 in the door nearly totally.
- this seal consisting of a pressdrawn section in a resinous material, is characterized by a succession of four tubular elements, 8, 9, 10, 11 and an L-shaped side element, 12, with its smaller wing connected to the wall of tubular element 9 and its larger wing positioned almost parallel to the internal flat face that is common to tubular elements 9 and 10.
- Tubular element 8 that has a rather rigid and nearly quadrangular shape, is provided, on the outside of the opposed side walls, with reliefs 21, in the shape of saw teeth, for ease of entry and clamping into the corresponding parts of the grooved seat in pillar 1 where it is inserted, and the pillar seat walls can be suitably knurled in order for them to be coupled with the above-mentioned tubular element.
- Tubular element 9 is shaped this way so that it may be used with infrared rays, and any interruption or variation in their intensity due to element 9 being deformed by any anomalous external stress, would cause the safety devices to block the movement of the door.
- tubular element 9 towards the outside of the door is integral with the attachment of the smaller side of L-shaped element 12.
- Tubular element 11 forms the most advanced external part in the gap between fixed pillar 1 and door pillar 2 and, having the approximate shape of a peak, shares the semi-rigid wall of tubular element 10 that supports it.
- the remaining wall 13 of said tubular element 11 is reduced in thickness and made of a flexible elastically yielding material.
- door pillar 2 is provided with seal 4 so that it is functional with tubular element 11, with elastically yielding wall 13 of opposing seal 3 applied on pillar 1.
- this seal 4 consisting of a pressdrawn section in a resinous material, is characterized by flat laminar base 15, whose back is provided with V-shaped appendages so that it can be fitted onto the dovetail grooved seat in pillar 2 of the door and its front is provided, on the outward-facing side of the door, with a tubular element forming ribbing 16 and, on the opposite side, with elastically yielding flexible wing 17 that has a curvilinear configuration slanting towards the inside of flat laminar base 15.
- Appendages 14 and laminar base 15 are made of a rigid material while tubular ribbing 16 is made of a semi-rigid material and appendage 17 is made of an elastically yielding material.
- the outside surface of ribbing 16 is characterized by a series of close scores.
- Seal 5 applied onto protrusion 19 of pillar 1 protruding inwards towards the gap between pillar 1 and door pillar 2, is provided with elastically yielding large laminar wing 20 and its function is to limit free access to the above-mentioned gap between pillar 1 and pillar 2 and to shield the area of the grooved rail of pillar 1 where the door suspension pin is during the door movement.
- seals 3 and 4 that engage into each other during the door movement are emerging tubular element 13 in seal 3 of the fixed frame, flexible wing 17 and semi-rigid ribbing 16 in seal 4 that is applied onto the door pillar.
- Figure 13 shows the following position in the inward movement (or in the outward returning movement) of door 2 and it must be noted that, in comparison with Figure 12 the reciprocal position of door 2 and frame 1 is one of maximum compression of yielding element 13 of seal 3 due to the crossing with ribbing 16 of seal 4 during the inward movement (or outward returning movement) of door 2.
- Figure 14 shows the following position in the inward movement of door 2 and it must be noted how yielding element 13 of seal 3 overtakes (and starts to move away from) ribbing 16 of seal 4 during the inward movement of door 2 (or outward movement again once flexible element 13 moves against ribbing 16 of door 2 again).
- Figure 15 shows how yielding element 13 of seal 3 is deformed vertically while crossing over ribbing 16 of seal 4.
- Figure 16 shows the reciprocal position of part "c" of door 2 that is below suspension pin 18 and part "a" of frame 1 in which case it is the position at the start of the outward movement of door 2 where yielding element 13 of seal 3 causes wing 17 of seal 4 to bend without being deformed.
- Figure 17 shows that the reciprocal position of part "c" of door 2 and frame 1 in the following stage of the outward movement is one of maximum deformation of wing 17 of seal 4 ready to disengage from yielding element 13 of seal 3 without said yielding element 13 being deformed during overtaking.
- Figure 18 shows that the reciprocal position of part "c" of door 2 and frame 1 in the return movement of door 2 from the outside towards the closing plane is one of initial engagement of yielding element 13 of seal 3 against wing 17 of seal 4 without any noticeable deformation.
- Figure 19 shows that the reciprocal position of part "c" of door 2 and part "a" of frame 1 during the following stage in the return movement of door 2 from the outside towards the closing plane is one of maximum deformation of wing 17 of seal 4 due to the pressure of overtaking and completing the door closure by yielding element 13 in seal 3.

Abstract
Description
- The normal up-and-over door adopted to close a garage includes a mobile part that is a door and a fixed frame. When suspended, the door is balanced and has rods provided with end hinges where the top rods are hinged at the top of the fixed frame pillars.
- When the door is opened, the lifting pins that are integral to the door slide in the grooved rails of the frame side pillars while the rods connecting the door to the frame force the door to tilt more and more in respect of the pillars while going up so that the top part of the door, above the pins, folds inside the garage and the bottom part, below the pins, protrudes otwards. When fully opened, the door reaches the top of the hole and,its position is nearly completely horizontal and transversal to the frame pillars.
- At the moment, for safety reasons, recent regulations state that the gap between the door sides and the frame pillars must be consistent with the existing structures so that fingers and hands cannot be trapped accidentally.
- Apart from, the normal regulations issued to ensure the safety of the moving parts by determining the space between the door and the fixed frame even when the door is motor-driven, certain stress values must not be exceeded, so that the moving door, even under the stress caused by any occasional obstacles hampering its movement, must stop.
- It is self-evident that a system of suitable seals must be used to fill the above-mentioned gap.
- The difficulty in solving the above-mentioned problems, that is how to create a seal between parts that cross over along the sides, still troubles today's manufacturers of up-and-over doors.
- Another problem to overcome, common to all existing systems, is a rather laborious installation and difficult replacement.
- A further problem in the seals of known systems is that, due to the scraping of the moving parts against the fixed parts, the seal integrity is jeopardized because of wear and tear.
- Another problem due to the scraping of the seals against the varnished door parts is the wear and tear of the paint in either the door or the frame with the consequence that parts are exposed to rust corrosion.
- A further disadvantage of the sealing system actually on the market is that, due to its necessarily rather rigid configuration when the door is closed, (caused by the closeness of the fixed part to the moving part) it does not always fill the gap required for the door to move or the gap caused by the door being out of squareness.
- The aim of the solution set out in this patent is to solve all the above-mentioned problems and give all the added advantages described in the following non restrictive solution.
- The solution that allows to overcome fully all the above-mentioned problems entails the adoption of the seals that are the subject of this patent.
- The main problem for the seals that need to fill the gap is that they have to meet contrasting requirements that may be overcome with difficulty.
- The aim to be achieved is for them to guarantee sealing during the door movement without creating unacceptable friction in respect of the stress limits demanded by market requirements that cannot be exceeded by the door, as explained above when the example of the stress limits due to an obstacle encountered while moving was mentioned.
- It is necessary to take into account that the already considerable width between the door and the frame pillars required by the regulations in force might be increased, while the door is moving, by the fixed frame and the door being ,out of squareness due to either construction or installation problems.
- A further aim for this patent is to create a sealing system that is as tight as possible so that the amount of water, air and light getting through is minimized.
- Another aim of this patent is for the sealing system not to create such friction during the door movement as to exceed the limit values demanded by market requirements should the door meet an obstacle.
- A further aim for this patent is that the sealing system must be structured in such a way that the scraping between the moving and fixed seals should ensure a satisfactory life span.
- The patented sealing system accomplishing all of the above aims and offering all the above-mentioned advantages is made up of two seals, one applied to the frame pillar and another one to the door adjoining side edge as described underneath.
- A resinous seal is applied on a grooved seat on each frame pillar, that includes: a semi-rigid attachment that, in continuity with a semi-rigid structure that expands in the gap outwardly towards the door, supports a flexible elastically yielding tubular configuration that is suitable to enter the practically-configured C-shaped seat of the adjoining door seal.
- The attachment that is inserted into the pillar grooved seat has a tubular quadrangular shape that matches the seat cavity it has to anchor to, its sides being provided with a series of tilted vertical tabs in the shape of saw teeth.
- To increase the sturdiness of the fit and prevent the inserted attachment from rocking due to the stress the seal is under during the door movement, the walls of the pillar grooved seats are appropriately knurled.
- The semi-rigid external structure in direct continuity with the attachment consists of a tubular, almost cylindrical element that is reinforced on the door interior side by an atypical semi-rigid tubular quadrangular configuration that goes from the side almost to the most external central part and that supports an overhanging pronounced semi-rigid wing on the external side.
- A flexible arched tubular element, protruding towards the inside of the gap available towards the door branches off from the edges of the rigid side of the atypical tubular quadrangular configuration.
- A thin film of fretting-proof material with anti-friction properties is coextruded on the most external part of said flexible element.
- The tubular almost cylindrical configuration in direct continuity with the attachment is realized this way as a prearrangement for possible infrared rays that, following the deformation of the tubular section due to anomalous stress may act as a safety device and block the movement of the door.
- A resinous seal is applied on each side pillar of the door that, seen from the front-end, has a rigid flat laminar base provided with V-shaped appendages on its back so that it can be fitted into the pillar dovetail grooved seat and provided, on its front, in correspondence with the side towards the door external surface, with semi-rigid tubular vertical ribbing and on its opposite side with a flexible eleastically yielding wing with a thin-walled elastically yielding curvilinear configuration tilted towards the internal flat laminar base.
- The purpose of the semi-rigid tubular vertical ribbing is to reduce friction when this ribbing rubs against the opposite seal during the door movement.
- The function of this seal is to allow an element of the frame adjoining seal to be inserted in order to obtain a tight fit.
- With the door closed the two seals fill the gap totally since the protruding part in one seal fits the cavity in the other seal perfectly.
- When the door is opened, the uncoupling of the two seals can be described as follows.
- When the door is lifted and the corresponding pins start to slide on the pillar rails, the door also starts to swing on these pins due to the action of the rods that, whose bottom ends are hinged to the door and top ends to the tops of the pillars.
- When the door starts to lift and tilt, protruding from the door hole, and the angle increases from 0 to 90 degrees, the seals on the part of door below the lifting pins overtake each other, crossing and sliding on each other, without any stress, together with the protruding part of the pillar seal that is positively yielding.
- The semi-rigid ribbing of the door seal is free and moves towards the outside, while the sliding and overtaking is taken over by the opposing flexible wing of the door seal.
- As the door goes on protruding from the door hole and tilting inwards, the door seals above the lifting holes overtake and cross over each other at an angle that goes from 0 to 90 degrees and scrape and slide on each other.
- Now the semi-rigid ribbing of the door seal overtakes and crosses over both the tubular flexible configuration (seat) of the pillar seal and the opposing contiguous elastically yielding wing of the pillar seal.
- The progressive compression of the top of the pillar flexible tubular element by the semi-rigid ribbing in the door seal takes place during the initial opening (and then closing) phase, affecting simultaneously the whole length above the door hinge pins to go down, when the door is completely open, to a short length because the two directixes of the seals are at 90 ° from each other.
- To prevent the parts from wearing because of their sliding on each other and rubbing against the pillar arched tubular surface, as previously stated, the seal is provided with a very thin film of anti-friction and wear-resistant material.
- For the sliding not to cause any noise if the flexibility of the materials is not efficient enough, the surface of the film is provided with tiny noise-absorbing papillae.
- It must also be noted that a third seal is fitted on the pillar, whose purpose is not tightness and that, located on the inside of the door closing hole, is used to reduce accessibility to the gap created between the frame pillar and the door pillar when the door is closed, and to shield the area where the pin supporting the door during its movement on the rail is located.
- To achieve the purpose in a way different from what is available on the market, the perimeter of the door has been provided with suitable seals.
- Both seals shielding the gap between the frame and the door have fairly rigid external sides to protect from external intrusions but, at the same time, they are sufficiently yielding to ensure fingers and hands are not cut off in an accident.
- All of the above is clarified if the drawings are examined.
- Figure 1 is a top transversal view of just one side of the vertical structure of an up-and-over door consisting of the fixed frame pillar and the door pillar, both fitted with the seals that are the subject of this patent that seal the gap between the frame and the door.
- Figure 2 is like Figure 1 but one seal is added to the strengthening protrusion on the fixed frame pillar that is farther away from the external wall. This seal has the function to limit the access to the empty space between the fixed frame and the moving door and to shield the area of the grooved rail where the door suspending pin is when the door moves.
- Figure 3 is the axonometric projection from the outside and from the top of Figure 1.
- Figure 4 is the axonometric projection from the inside and from the top of Figure 1.
- Figure 5 is the axonometric projection, in isolation, from the top of the seal that is to be applied to the grooved seats present on the sides of the door side pillars.
- Figure 6 is the axonometric projection, in isolation, of the seal that is to be applied to the grooved seeats present on the internal sides of the fixed frame pillars.
- Figure 7 is the axonometric projection, in isolation, of the seals in Figures 5 and 6 when they engage each other during the door movement.
- Figure 8 is the axonometric projection, in isolation, like Figure 7, of the seals shown in Figures 5 and 6 in a different position of engagement.
- Figure 9 is a side stylized drawing of an up-and-over door where the door is nearly closed (or just opening).
- Figure 10 is a side stylized drawing of the same up-and-over door as in Figure 9, where the door is half-way between total closure and total opening.
- Figure 11 is a top transversal view of just one side of the vertical structure of an up-and-over door consisting of a fixed frame pillar and of the up-and-over door pillar showing, in respect of Figure 1, an enlargement of the seals that are the subject of this patent.
- In the figure where the door is closed and the gap between the frame and the door is sealed, the protruding tubular elastically yielding part of the seal fitted on the pillar of the fixed frame is inserted into the cavity of the seal fitted onto the side pillar of the door as a support for its relative semi-rigid tubular ribbing without any deformation whatsoever.
- Figures 12, 13, 14 and 15 show the succession of different engagement positions of the two seals in the pillar and in the door in respect of the part of door that is above its supporting pin during the opening (and closing) of the door.
- Figures 16, 17, 18, and 19 show the succession of different engagement positions of the two seals in the pillar and in the door in respect of the part of door that is below its supporting pin during the opening (and closing) of the door.
- From the examination of the figures one can see that the seals that are the subject of this patent have been planned in order to close the gap between the pillars of the fixed frame and the side pillars of the door which is necessary for safety reasons and for the purpose of not exceeding certain stress values during the movement of the door even if it is motor-driven.
-
Seal 3 is fitted onto the grooved seat ofpillar 1 in the fixed frame and its outside part extends and fills the gap betweenpillar 1 in the frame and pillar 2 in the door nearly totally. - From a front-end view, this seal, consisting of a pressdrawn section in a resinous material, is characterized by a succession of four tubular elements, 8, 9, 10, 11 and an L-shaped side element, 12, with its smaller wing connected to the wall of
tubular element 9 and its larger wing positioned almost parallel to the internal flat face that is common totubular elements -
Tubular element 8, that has a rather rigid and nearly quadrangular shape, is provided, on the outside of the opposed side walls, withreliefs 21, in the shape of saw teeth, for ease of entry and clamping into the corresponding parts of the grooved seat inpillar 1 where it is inserted, and the pillar seat walls can be suitably knurled in order for them to be coupled with the above-mentioned tubular element. - The adjoining
tubular element 9, that is made of a resinous material as well, is on the outside, has a nearly circular shape and shares parts of its wall with tubularhollow element 8 and with tubular almosttrapezoidal element 10. -
Tubular element 9 is shaped this way so that it may be used with infrared rays, and any interruption or variation in their intensity due toelement 9 being deformed by any anomalous external stress, would cause the safety devices to block the movement of the door. - The wall of
tubular element 9 towards the outside of the door is integral with the attachment of the smaller side of L-shapedelement 12. - Tubular element 11 forms the most advanced external part in the gap between fixed
pillar 1 anddoor pillar 2 and, having the approximate shape of a peak, shares the semi-rigid wall oftubular element 10 that supports it. - The remaining
wall 13 of said tubular element 11 is reduced in thickness and made of a flexible elastically yielding material. - Also
door pillar 2 is provided withseal 4 so that it is functional with tubular element 11, with elastically yieldingwall 13 of opposingseal 3 applied onpillar 1. - From a front-end view, this
seal 4, consisting of a pressdrawn section in a resinous material, is characterized by flatlaminar base 15, whose back is provided with V-shaped appendages so that it can be fitted onto the dovetail grooved seat inpillar 2 of the door and its front is provided, on the outward-facing side of the door, with a tubularelement forming ribbing 16 and, on the opposite side, with elastically yieldingflexible wing 17 that has a curvilinear configuration slanting towards the inside of flatlaminar base 15. - Appendages 14 and
laminar base 15 are made of a rigid material whiletubular ribbing 16 is made of a semi-rigid material andappendage 17 is made of an elastically yielding material. The outside surface of ribbing 16 is characterized by a series of close scores. - It must be noted that, so that it can be easily understood, in the drawings, with the exception of Figure 1,
laminar base 15 does not seem to be fully supported while in reality it is totally and forcefully supported with its back againstpillar 2, where it is applied. -
Seal 5, applied ontoprotrusion 19 ofpillar 1 protruding inwards towards the gap betweenpillar 1 anddoor pillar 2, is provided with elastically yielding largelaminar wing 20 and its function is to limit free access to the above-mentioned gap betweenpillar 1 andpillar 2 and to shield the area of the grooved rail ofpillar 1 where the door suspension pin is during the door movement. - The parts of
seals tubular element 13 inseal 3 of the fixed frame,flexible wing 17 andsemi-rigid ribbing 16 inseal 4 that is applied onto the door pillar. ' - On the basis of the structural description of
seals - The examination of Figure 11 shows that the reciprocal position of
door 2 and fixedframe 1 is closed and yieldingend 13 ofseal 3 forms a sealing fit with ribbing 16 ofseal 4. - As shown, also
flexible wing 17 ofseal 4 creates a sealing fit with yieldingelement 13 of the seal and they work together to keep light and air out. - The examination of Figure 12 shows that the reciprocal position of part "a" of
door 2 that is abovesuspension pin 18 and the top part offrame 1 is the initial (or final) movement ofdoor 2 towards the inside and yieldingelement 13 ofseal 3 is compressed againstribbing 16 ofseal 4. - The examination of Figure 13 shows the following position in the inward movement (or in the outward returning movement) of
door 2 and it must be noted that, in comparison with Figure 12 the reciprocal position ofdoor 2 andframe 1 is one of maximum compression of yieldingelement 13 ofseal 3 due to the crossing withribbing 16 ofseal 4 during the inward movement (or outward returning movement) ofdoor 2. - The examination of Figure 14 shows the following position in the inward movement of
door 2 and it must be noted howyielding element 13 ofseal 3 overtakes (and starts to move away from) ribbing 16 ofseal 4 during the inward movement of door 2 (or outward movement again onceflexible element 13 moves against ribbing 16 ofdoor 2 again). - Figure 15 shows how yielding
element 13 ofseal 3 is deformed vertically while crossing overribbing 16 ofseal 4. - Figure 16 shows the reciprocal position of part "c" of
door 2 that is belowsuspension pin 18 and part "a" offrame 1 in which case it is the position at the start of the outward movement ofdoor 2 where yieldingelement 13 ofseal 3 causeswing 17 ofseal 4 to bend without being deformed. - Figure 17 shows that the reciprocal position of part "c" of
door 2 andframe 1 in the following stage of the outward movement is one of maximum deformation ofwing 17 ofseal 4 ready to disengage from yieldingelement 13 ofseal 3 without said yieldingelement 13 being deformed during overtaking. - Figure 18 shows that the reciprocal position of part "c" of
door 2 andframe 1 in the return movement ofdoor 2 from the outside towards the closing plane is one of initial engagement of yieldingelement 13 ofseal 3 againstwing 17 ofseal 4 without any noticeable deformation. - Figure 19 shows that the reciprocal position of part "c" of
door 2 and part "a" offrame 1 during the following stage in the return movement ofdoor 2 from the outside towards the closing plane is one of maximum deformation ofwing 17 ofseal 4 due to the pressure of overtaking and completing the door closure by yieldingelement 13 inseal 3. - All of the above shows the importance of the innovation brought about by this patent that revolutionizes the systems used up until this moment. The patent does not exclude any improvements that experts in this field might bring in by using the principles of this patent.

- Seals to be applied to up-and-over doors in order to close the gap between pillar (1) of the fixed frame and the pillar of door (2) characterized by the fact that the structure of the press-drawn section in a resinous material of at least one seal (3), consists, both for the semi-rigid part and for the elastically yielding flexible part, of a series of tubular elements (8, 9, 10, 11) whose intermediate tubular elements (9) between the attachment tubular element (8) and the end tubular element (13), create an internal section of flat wall (3) and the intermediate circular cross section element (9) adjoining the quadrangular cross section tubular element (8) to be inserted into the grooved seat of the pillar it is applied to, is integral with the smaller side of L-shaped element (12) having its larger side turned towards the gap and being parallel to,the internal wall (3).
- Seals to be applied to up-and-over doors in order to close the gap between the pillar of the fixed frame and the pillar of the door in accordance with one or more of the previous claims characterized by the fact that one of the seals (4) made of a press-drawn section in a resinous material consists of a rigid flat laminar base (15) with, on its back, two V-shaped almost rigid appendages (14) that are to be inserted into a dovetail groove and provided on its front, in correspondence with its external wall, with a pronounced semi-rigid ribbing (16) and, in correspondence with its internal wall, with a flexible eleastically yielding wing (17) that arches towards the centre of the base (15).
- Seals to be applied to up-and-over doors in order to close the gap between the pillar of the fixed frame and the pillar of the door in accordance with one or more of the previous claims characterized by the fact that on the part of the surface of flexible elastically yielding element (13) of seal (3) that is compressed and scraped a thin flexible film of non-stick and wear-proof material is applied that can be coextruded onto said flexible elastically yielding material (13).
- Seals to be applied to up-and-over doors in order to close the gap between the pillar of the fixed frame and the pillar of the door in accordance with the previous claim characterized by the fact that the non-stick and wear-proof film applied to the surface of elastically yielding element (13) of one (3) of the two seals is provided with a series of papillae in order to prevent ribbing (16) or flexible wing (17) of opposing seal (4) from creaking or grating while scraping on it.
- Seals to be applied to up-and-over doors in order to close the gap between the pillar of the fixed frame and the pillar of the door in accordance with claim 4 characterized by the fact that the external surface of ribbing (16) turned towards the external side of rigid flat lamina (15) of one of the two seals (4) is provided with a series of vertical close scores aiming at reducing the friction caused by ribbing (16) when it engages flexible elastically yielding part (13) of opposing seal (3) during the movement of door (2).
- Seals to be applied to up-and-over doors in order to close the gap between the pillar of the fixed frame and the pillar of the door in accordance with one of the previous claims characterized by the fact that in order to block access to the gap between' fixed frame (1) and pillar (2) of the door towards the internal parts of seals (3, 4) that close the gap, a resinous angled extrudate (5) with hooked ends and from whose external edge (5) a wide wing (20) in flexible elastically yielding material departs that covers nearly totally the access to said gap, is fitted onto a strengthening protrusion (19) of pillar (1) of the frame.
- Seals to be applied to up-and-over doors in order to close the gap between the pillar of the fixed frame and the pillar of the door in accordance with the previous claim characterized by the fact that said wide wing (20) creates a shield for the grooved rail of pillar (1) along which pin (18) of door (2) slides.
