Definitions
- the present invention belongs to the field of construction, more precisely to the field of door for special purposes, particularly for preventing fire expansion.
- the invention relates to automatic sliding fire door, which can operate in a sliding or swing operating mode, wherein no protruding components such as door handles and panic bars are required for opening said door.
- Automatic sliding fire door is intended for installation on borders of fire sectors as well as on escape routes. Most commonly such doors are used for prevention of fire expansion, wherein safe evacuation of people has to be enabled. They may be used in residential buildings, hospitals, shopping malls, industrial and business spaces, health institutions and buildings for accommodation of tourists.
- Existing automatic sliding fire door combine automatic sliding operation (in usual conditions) and in manual swing operation triggered by a fire alarm, electricity power failure or working error, when the doors are automatically sliding closed and switched to operation as manual swing door, which can be opened with a door handle or a panic bar.
- the technical problem which is solved by the present invention, is construction of such automatic sliding fire door for escape routes that on their outer visible surfaces do not have any functional fittings, such as locks, door handles and/or panic bars or similar elements, as in sliding mode of operation these elements represent possible sources of injuries of users, while at the same time their installation on the door means more complicated design and a larger number of components, as well as increase the opening force.
- the aim of the invention is thus to ensure simplified automatic sliding fire door for escape routes without any functional or safety elements, i.e. without any protruding components. This simplification results in lower number of components and assemblies, which consequently improves door reliability, leads to lower pricing, simplified use in emergency cases, and additionally improves architectural aesthetic.
- Automatic sliding fire door with a swing leaf as described in patent SI 21048 are equipped with a mechanical forced closing system, which in emergency cases ensures unconditional sliding closure, latching of the sliding leafs and unlatching swing leaf, which are a component of the sliding leafs or are attached to the sliding doorframe with hinges.
- the sliding leaf In emergency cases such as a fire alarm or electricity power failure, the sliding leaf are closed and latched, while the swing leaf may be opened with a lever handle, a panic bar or similar.
- the mechanical system for closing and latching the sliding leaf and unlatching the swing leaf is based on stored potential energy of lifted weights or compressed pressure springs.
- the components enabling opening and closing the swing leafs such as locks, door handles, panic bars, elements for self-closing swing leafs and systems for synchronized closure of swing leafs, are installed on the surface of the leaf.
- Such design is potentially dangerous for users, as in normal operation of doors (sliding); the said components protrude out of the leaf surface. If they were not present, the doors could not be opened, hence they are essential.
- Patent SI 22012A discloses automatic fire door with the same mode of operation and transformation from sliding operation to an emergency operation as described in patent SI 21048 .
- the difference is in the construction of components that ensure the transformation from the normal sliding operation into the fire mode of operation.
- the energy for closing the sliding leaf during transformation into fire mode is provided with the potential energy of tensed spiral springs, wherein the systems for latching the sliding leafs and unlatching the swing leafs are managed with electromagnetic actuators.
- the components for closing and self-closure of swing leafs are installed on the outer surface of the leafs.
- the object of the present invention is automatic sliding fire door for escape routes with one or more sliding leafs.
- the sliding leaf comprises a sliding doorframe and a swing leaf, which is with hinges mounted on the sliding doorframe, wherein in case of a fire, the sliding leafs are unconditionally closed in the first step, and thereafter swing leaf may be opened in the second step, for 90 or more degrees, allowing passage through the door in emergency.
- Said automatic sliding fire door thus have two operation modes:
- the automatic sliding fire door which enables that surfaces of sliding leafs are without protruding components, hence without door fittings (locks, panic bars, door handles).
- the essence of the automatic sliding fire door is in that passage in case of a fire is from one side enabled by pushing the swing door with a push and from the other side with pulling a recessed handle.
- the automatic sliding fire door comprises:
- the longitudinal holder (door drive unit) has a guide, on which trolleys with guide wheels are moved, wherein at least one sliding leaf is mounted on the trolleys.
- the sliding leaf comprises the sliding doorframe and the swing leaf, which is attached to the sliding doorframe with hinges.
- the drive assembly moves, opens and closes, respectively, at least one sliding leaf.
- the assembly for forced closure in case of emergency closes at least one sliding leaf with use of stored kinetic energy in tensed springs.
- the closure for automatic closing of the swing leaf is preferably the same as described in document SI 22012 , with a difference that it is integrated only in the sliding doorframe.
- An automatic closure of the swing leaf is important for prevention of swing opening during normal sliding mode of operation. In case of an alarm, the sliding leaf is forced to close, the said closure is released and the door leaf may open in the swing mode.
- the sliding doorframe is preferably pre-tensed, which solves the problem of doorframe sagging in case of swing operation.
- the doorframe sagged or touched the floor due to weight of the leaf, leading to impaired operation. Therefore, these solutions integrated a latch for blocking the bottom side for sliding frame in case the door is operating in swing.
- the sliding doorframe is pre-tensed in the following manner: the sliding doorframe has through an empty space of the vertical profile, through a hole in the horizontal frame and through a hollow attachment of the carrier horizontal profile inserted two tension rods, which are fixed into an attachment plate on the bottom part of the vertical profile. On hollow attachments the rods are screwed with a nut, which is at the same time also a regulation element for setting the pre-tension of the sliding doorframe.
- the present invention does not require a mechanism for synchronized automatic closing of swing door leafs, as in one-leaf door the vertical connection between the swing leaf and the fixed doorframe in the wall or in double-leaf door the vertical connection between two swing leafs does not have a rebate, as flexible tube seals are installed in the groove, so that opening and automatic closing of leafs is possible in any sequence, even at the same time.
- the flexible seals on the vertical connection between the leaf and the doorframe in one-leaf door and between the left and right leaf of the double leaf door enable reliable sealing.
- the described constructional design additionally allows manufacturing of swing door leafs without horizontal crossbar profiles, so that uniform glass or panels may be installed in the door leafs, which contributes to improved aesthetic appearance of the door.
- the automatic sliding fire door Due to thermal conditions during a fire the glazing beads used for fixing and protection of glass or panels tend to fall out, the automatic sliding fire door according to the invention this problem solve with thin and narrow metal plates attached to the glazing beads.
- the glass or the panel protect the glazing beads during a fire, while the glazing beads protects the groove around the glass or the panel from falling out, which are usually a weak point for leaking smoke and/or fire.
- the sliding doorframe according to the invention is comprises carrier profiles and anti-fire profiles, which are preferably connected with so called twin slot fixing, which eliminates the need for welding that causes profile deformation and lowers door quality.
- carrier profiles and anti-fire profiles are preferably connected with so called twin slot fixing, which eliminates the need for welding that causes profile deformation and lowers door quality.
- elongated holes are cut-out along both sides, wherein the holes are distributed in a particular raster.
- the carrier profile is provided with protruding tabs with the same raster as holes, but with a certain shift, so that when the tabs are inserted into the holes on the anti-fire profile and the carrier profile is slid (pushed) in the direction of the notch on the tabs, a strong connection is achieved between both profiles.
- the solution of the automatic sliding fire door for escape routes may be used for one-leaf and double-leaf door with any type and dimension of anti-fire profiles and anti-fire glass.
- Said doors may be installed in wall and glass openings in escape routes and allow simple and safe evacuation of people and objects in an early stage of fire, while at the same time prevent expansion of fire and smoke for at least a certain time.
- Figure 1a shows a double-leaf automatic sliding fire door from the inner side installed in a fire wall 1, which separates two fire sectors.
- a longitudinal holder (door drive unit) with a guide (drive unit) 2 is mounted, wherein trolleys 5 with guide wheels arranged to move along the said guide 2, and wherein sliding leaf 6 are installed onto the trollies 5.
- the sliding leaf 6 comprises a sliding doorframe 6a and a swing leaf 6b, which is attached to the said doorframe with hinges 7.
- a drive assembly 3 moves or opens and closes the sliding leafs 6.
- the assembly 4 for forced closure in case of emergency with stored kinetic energy in tensed springs closes the sliding leafs 6 in a forced manner.
- Figure 1b shows a possible installation of a recessed handle for opening the door from the external side.
- Figure 2 shows a connection of two front profiles 8 and 11, which are a part of the frame of the swing leafs 6b, when the sliding leafs 6 are closed in normal operation or in fire operation, when the sliding leafs are closed in a forced manner.
- the slot 10 is sealed with tube seals 9 and 9a, which are inserted into a groove 8a of the profile 8 and into a groove 11a of the profile 11.
- the profile 8a may be the profile of the doorframe in single leaf system or a profile of the doorframe of the opposite swing leaf.
- the swing door leafs are without a rebate
- the groove 10 between the swing leafs 6b and doorframe made of fire profile 8 or between two swing leafs are sealed with tubular seals 9 and 9a, which prevent transfer of smoke and flame.
- Tubular flexible seals 9 and 9a due to their shape and characteristics of the material from which they are made, prevent transfer of smoke and flames, while at the same time they allow any sequence of opening and closing of the swing leafs. Therefore, the leafs may be opened from the inner side by pushing one of the leaf or both leafs at the same time.
- FIG 3 cross-section B - B.
- the fire profile 13 with a flange 13a is fixed to the vertical profile 18 of the sliding doorframe 6a.
- the flange 13a is moved into the inner space of the slot 15a of the sealing profile 15 installed on the L profile 14, which is fixed on the wall 1.
- two membrane seals 16 and 16a are installed into channels 15b and 15c in the inner space 15a, the said seals enclose the flange 13a.
- Safety rubber 12 is glued along the entire length of the vertical profile 11 of the sliding doorframe 6a.
- the safety rubber is a safety element, as its shape and characteristics of the material from which it is made, ensure that the push force at door closing is decreased for approximately 60%.
- the sliding doorframe 6a is one of the elements of the sliding leaf 6 and it is with trollies with wheels 5 mounted on the longitudinal holder - door drive with the guide 2 and connected with the drive assembly 3, the latter translationally moving the doorframe into closed or open position.
- the swing leaf 6b is attached with hinges 7, thus the doorframe 6a and swing leaf 6b creating the sliding leaf 6.
- the sliding doorframe does not need a latch for blocking sliding doorframe, which prevents movement and sagging of the sliding doorframe in the fire mode, when swing doors are in use.

Abstract
Description
- The present invention belongs to the field of construction, more precisely to the field of door for special purposes, particularly for preventing fire expansion. The invention relates to automatic sliding fire door, which can operate in a sliding or swing operating mode, wherein no protruding components such as door handles and panic bars are required for opening said door.
- Automatic sliding fire door is intended for installation on borders of fire sectors as well as on escape routes. Most commonly such doors are used for prevention of fire expansion, wherein safe evacuation of people has to be enabled. They may be used in residential buildings, hospitals, shopping malls, industrial and business spaces, health institutions and buildings for accommodation of tourists. Existing automatic sliding fire door combine automatic sliding operation (in usual conditions) and in manual swing operation triggered by a fire alarm, electricity power failure or working error, when the doors are automatically sliding closed and switched to operation as manual swing door, which can be opened with a door handle or a panic bar.
- The technical problem, which is solved by the present invention, is construction of such automatic sliding fire door for escape routes that on their outer visible surfaces do not have any functional fittings, such as locks, door handles and/or panic bars or similar elements, as in sliding mode of operation these elements represent possible sources of injuries of users, while at the same time their installation on the door means more complicated design and a larger number of components, as well as increase the opening force. The aim of the invention is thus to ensure simplified automatic sliding fire door for escape routes without any functional or safety elements, i.e. without any protruding components. This simplification results in lower number of components and assemblies, which consequently improves door reliability, leads to lower pricing, simplified use in emergency cases, and additionally improves architectural aesthetic.
- Automatic sliding fire door with a swing leaf as described in patent SI 21048 are equipped with a mechanical forced closing system, which in emergency cases ensures unconditional sliding closure, latching of the sliding leafs and unlatching swing leaf, which are a component of the sliding leafs or are attached to the sliding doorframe with hinges. In emergency cases such as a fire alarm or electricity power failure, the sliding leaf are closed and latched, while the swing leaf may be opened with a lever handle, a panic bar or similar. The mechanical system for closing and latching the sliding leaf and unlatching the swing leaf is based on stored potential energy of lifted weights or compressed pressure springs. The components enabling opening and closing the swing leafs such as locks, door handles, panic bars, elements for self-closing swing leafs and systems for synchronized closure of swing leafs, are installed on the surface of the leaf. Such design is potentially dangerous for users, as in normal operation of doors (sliding); the said components protrude out of the leaf surface.
If they were not present, the doors could not be opened, hence they are essential. - Patent
SI 22012A SI 21048 - All known solutions disclose doors with functional elements as they cannot be opened in any other way. The invention differs from these known solutions in that the said functional elements are not needed, because door opening is enabled in a different manner.
- The object of the present invention is automatic sliding fire door for escape routes with one or more sliding leafs. The sliding leaf comprises a sliding doorframe and a swing leaf, which is with hinges mounted on the sliding doorframe, wherein in case of a fire, the sliding leafs are unconditionally closed in the first step, and thereafter swing leaf may be opened in the second step, for 90 or more degrees, allowing passage through the door in emergency. Said automatic sliding fire door thus have two operation modes:
- sliding mode, when in normal conditions the sliding leafs translationally move between open and closed positions;
- fire mode initiated for example with a fire alarm or electricity power failure, when a mechanical system using stored potential energy in tensed springs unconditionally closes the sliding leaf(s) and unlatch the swing leafs, so that passage through the door is enabled. The swing leaf is unlatched in the same manner as described in patent
SI 22012 - The above described technical problem is solved with a construction of automatic sliding fire door, which enables that surfaces of sliding leafs are without protruding components, hence without door fittings (locks, panic bars, door handles).
The essence of the automatic sliding fire door is in that passage in case of a fire is from one side enabled by pushing the swing door with a push and from the other side with pulling a recessed handle. In order to allow such opening, the automatic sliding fire door comprises: - a longitudinal holder (door drive unit) with at least one sliding door leaf mounted via a trolley, so that the said sliding leaf can move in the sliding mode;
- the sliding door leaf comprises a swing leaf and a sliding doorframe, wherein the leaf is attached with at least one hinge to the mentioned doorframe for allowing swing mode of operation;
- a closure element for self-closing of the swing leaf is integrated in the profile of the sliding doorframe;
- a flexible seal tube placed in a groove between the leaf and the doorframe or between two leafs that allow pushing or pulling the leafs around the hinge in the swing door mode of operation;
- an assembly for forced closure of sliding door in case of fire alarm, electricity power failure or any other emergency, wherein the assembly comprises:
- ∘ Spiral springs attached to a housing of the assembly for forced closing and attached to the trolley with door leaf, guided on the guide, wherein a pulling rope is attached to the trolley, the pulling rope being wound on a drum,
- ∘ Said drum is mounted directly on a shaft of a gearbox, attached to the housing, wherein the said drum is mounted in a flange, which is attached to the housing;
- a recessed handle for pulling the door leaf in the swing mode, installed on at least one door leaf.
- The longitudinal holder (door drive unit) has a guide, on which trolleys with guide wheels are moved, wherein at least one sliding leaf is mounted on the trolleys. The sliding leaf comprises the sliding doorframe and the swing leaf, which is attached to the sliding doorframe with hinges. The drive assembly moves, opens and closes, respectively, at least one sliding leaf. The assembly for forced closure in case of emergency closes at least one sliding leaf with use of stored kinetic energy in tensed springs. The closure for automatic closing of the swing leaf is preferably the same as described in document
SI 22012 - The sliding doorframe is preferably pre-tensed, which solves the problem of doorframe sagging in case of swing operation. In known solutions, the doorframe sagged or touched the floor due to weight of the leaf, leading to impaired operation. Therefore, these solutions integrated a latch for blocking the bottom side for sliding frame in case the door is operating in swing. The sliding doorframe is pre-tensed in the following manner: the sliding doorframe has through an empty space of the vertical profile, through a hole in the horizontal frame and through a hollow attachment of the carrier horizontal profile inserted two tension rods, which are fixed into an attachment plate on the bottom part of the vertical profile. On hollow attachments the rods are screwed with a nut, which is at the same time also a regulation element for setting the pre-tension of the sliding doorframe.
- In comparison to known solutions the present invention does not require a mechanism for synchronized automatic closing of swing door leafs, as in one-leaf door the vertical connection between the swing leaf and the fixed doorframe in the wall or in double-leaf door the vertical connection between two swing leafs does not have a rebate, as flexible tube seals are installed in the groove, so that opening and automatic closing of leafs is possible in any sequence, even at the same time. At the same time the flexible seals on the vertical connection between the leaf and the doorframe in one-leaf door and between the left and right leaf of the double leaf door enable reliable sealing.
- The described constructional design additionally allows manufacturing of swing door leafs without horizontal crossbar profiles, so that uniform glass or panels may be installed in the door leafs, which contributes to improved aesthetic appearance of the door.
- Due to thermal conditions during a fire the glazing beads used for fixing and protection of glass or panels tend to fall out, the automatic sliding fire door according to the invention this problem solve with thin and narrow metal plates attached to the glazing beads. During insertion of glass into leafs and fixed walls said plates are pushed under the glass or a panel, wherein the friction force between the glass and the plate prevents the glazing beads from falling out of the leaf frame. Thus, the glass or the panel protect the glazing beads during a fire, while the glazing beads protects the groove around the glass or the panel from falling out, which are usually a weak point for leaking smoke and/or fire. This is of utmost importance for the invention, as the door may comprise large glasses or panels, which have to be reliably mounted even in cases of increased temperature during a fire.
- The sliding doorframe according to the invention is comprises carrier profiles and anti-fire profiles, which are preferably connected with so called twin slot fixing, which eliminates the need for welding that causes profile deformation and lowers door quality. Essentially, along the flaps-flanges of the anti-fire profiles elongated holes are cut-out along both sides, wherein the holes are distributed in a particular raster. The carrier profile is provided with protruding tabs with the same raster as holes, but with a certain shift, so that when the tabs are inserted into the holes on the anti-fire profile and the carrier profile is slid (pushed) in the direction of the notch on the tabs, a strong connection is achieved between both profiles.
- The solution of the automatic sliding fire door for escape routes may be used for one-leaf and double-leaf door with any type and dimension of anti-fire profiles and anti-fire glass. Said doors may be installed in wall and glass openings in escape routes and allow simple and safe evacuation of people and objects in an early stage of fire, while at the same time prevent expansion of fire and smoke for at least a certain time.
