Definitions

• the present invention relates to improvements in or relation to roller gates of the type as described in the preamble of claim 1.
• roller gates of the above mentioned type are often used in combination with more conventional wickets in the form of more heavy side wards hinged or sliding port lid members - where the quick roller gates are oper- ated during the working hours of the day, where the traffic with trucks in and out from the freezing house is of a considerate amount - while said more heavy side wards hinged or sliding port leaf members are used during the evening and nights, when the traffic with trucks through the gate is low or when the freezing house is closed.
• WO 2008/046422 discloses a previous roller gate suited as a starting point for this invention.
• the invention has for its purpose to provide a new and improved roller gate or door of the introductory mentioned type and by means of which may be achieved a very im- portant improvement in the operation of the roller gate or door during daily use where a great number of trucks are passing in and out to and from a freezing house or room.
• the roller gate or door according to the invention is characterised by that said one or more layers of said gate or door leaf at a first side of the gate or door leaf are factory- tailored with transverse directed pockets and with a smooth surface at an opposite side of the gate or door leaf - as said first side of the gate or door leaf is facing inwards when rolled up around said reel system.
• the gate or door leaf may be configured to be open when rolled up around a reel system operated by a driving mechanism.
• the gate or door leaf may consist of one or more layers of a flexible artificial web.
• One or more layers of said gate or door leaf may at a first side of the gate or door leaf be factory-tailored with transverse directed pockets and with a substantially flush surface at an opposite side of the gate or door leaf.
• the first side of the gate or door leaf may be facing inwards when rolled up around said reel system.
• roller gate may then actually isolate when rolled down and at the same time be able to roll up and thus provide a substantial improvement over prior art system that are often left open during the day due to limited isolation effect or slow roll-up / roll- down times.
• longitudinal block-shaped members arranged in or configured to be arranged in said first side of said gate or door leaf are provided with inwardly inclined side edges.
• the leaf with the longitudinal block-shaped member inserted into a pocket may be bent or rolled up since the inclined side edges leave a volume available so that the leaf can be rolled up.
• a person skilled in the art will adjust the inclination of the side edges to a particular radius of a rolled up leaf. This construction maintains isola- tion properties of the leaf.
• transverse directed pockets are provided with open ends for insertion of longitudinal block-shaped members of insulation material.
• the material may be Neoprene ® or similar foamed insulation material.
• first side is substantially flush when rolled down.
• first side surface is a plane surface when the leaf is rolled out or down. The surface is easily cleaned and does not accumulate dirt or particles. At the same time the first side surface ensures that insulation properties are improved.
• the first side surface and the opposite side surface may be substantially flush. Having identical longitudinal block-shaped members in the first side and identical longitudinal block-shaped members in the opposite side will provide an essentially uniform isolation that can be rolled up.
• first side transverse pockets on the first side are shifted relative to the transverse pockets on the opposite side in the roll-up/down direction.
• the transverse pockets in the first side with the inserted longitudinal block-shaped members have one or more volumes enclosed without the block-shaped members for bending when rolled up and isolating when rolled down.
• the final thickness of said longitudinal block-shaped members of the flexible gate or door leaf may have significant thickness of some 2 x 40 mm - as both the pockets at said first side and the pockets also at said opposite side are factory-tailored to be able to take-up rather thick longitudinal block-shaped mem- bers which in each layers have a thickness of some 40 mm.
• the roller gate according to the invention is such provided that said longitudinal block-shaped members at the inside of said gate or door leaf are provided with inwardly inclined side edges, hereby is a simple manner obtained that the gate or door leaf can be rolled more tightly rolled up on the reel system.
• the roller gate according to the invention may be such provided that said transverse directed pockets are provided with open ends for insertion of longitudinal block-shaped members of insulation material such as Neoprene ® or similar foamed insulation material.
• roller gate according to the invention may be such provided that said gate or door leaf at opposite side edges is adapted to be guided in vertical side guards which are provided with elongated electrical heating elements.
• the roller gate according to the invention may advantageously be such provided that said vertical side guards communicate with vertical channels leading - as a chimney - the generated heat air upwards to said reel sys- tern - the later may be placed above the roller gate either inside or outside a freezing room or house.
• the roller gate according to the invention may advantageously be such provided that said upper reel system being provided with a lower demountable flexible closure leaf consisting of one or more web layers filled with a suitable insulation material.
• the roller gate according to the present invention may be such provided that said vertical side guards being provided with a laser curtain extending in the range of 250 cm from the bottom of the gate- or doorway.
• roller gate according to the invention may be such provided that said transverse pockets at said open ends are provided with closure straps adapted to secure said inserted longitudinal block-shaped members of insulation material - hereby is in a simple manner obtained an easy way to secure that said block-shaped members are held in correct position in the gate or door leaf.
• the roller gate according to the invention may be such provided that said rolling up mechanism as known per see includes one or more tensioning webs positioned at said first side of the rolled up gate or door leaf and said opposite side of the rolled up gate or door leaf - as an upper end web part of said gate or door leaf is made without said longitudinal block-shaper members.
• said roller gate according to the invention as a pre-manufactured gate or door unit comprising an upper housing for said reel system and its belonging rolling up mechanism it may be advantageously that said housing at a transverse first side is caringly connected with upright supports at opposite sides of the roller gate and by means of inclined supports extending between said upright sup- ports and an opposite transverse side of the housing.
• pre-manufactured gate or door unit may be adapted to be mounted inside or outside a gate- or doorway to a freezing room or house.
• Fig. 1 shows a perspective view of a preferred embodiment for a roller gate according to the invention
• Fig. 2 shows a plane front view of the roller gate shown in Fig. 1
• Fig. 3 shows a sectional view of the roller gate according to Fig. 2 - as seen from a sectional line III-III of Fig. 2,
• Fig. 4 shows a sectional view of the roller gate according to Fig. 2 - as seen from a sectional line IV-IV of Fig. 2,
• Fig. 5 shows an enlarged sectional view of the roller gate according to Fig. 4 - as seen in the circle V of Fig. 4, and
• Fig. 6 shows a perspective exploded view of the preferred embodiment for a roller gate - as shown in the preceding figures.
• FIG. 6 shows a perspective exploded of a preferred embodiment for a roller gate or door 2.
• the shown embodiment for a roller gate or door 2 according to the invention is preferably built-up as a pre-manufactured unit which is suited for mounting in the gateway openings 4 of freezing rooms or freezing houses - that means that it don't matter whether the pre-manufactured roller gate unit is mounted at the inside or at the outside of the gateways opening 4.
• the roller gate 2 is of the type which is typically used in gateways 4 in industrial buildings such as freezing houses or the like, where the gate or door leaf 6 by opening is rolled up around an upper reel system 8 operated by a driving mechanism 10, and where the gate or door leaf 6 consists of one or more layers of a flexible artificial web such as a reinforced tarpaulin web of PVC or polyester.
• One or more layers of said gate or door leaf 6 is at a first side 12 of the gate or door leaf 6 factory-tailored with transverse directed pockets 14 and with a smooth surface at an opposite side 16 of the gate or door leaf 6 - as said first side 12 of the gate or door leaf 6 is facing inwards when rolled up around said reel system 8.
• roller gate 2 is as stated such provided that said trans- verse directed pockets 14 are provided with open ends 18 for insertion of longitudinal block-shaped members 20 of insulation material such as Neoprene ® or similar foamed insulation material.
• insulation material such as Neoprene ® or similar foamed insulation material.
• transverse pockets 14 at said open ends 18 are provided with closure straps 34 adapted to secure said inserted longitudinal block-shaped members 20 of insulation material.
• the thickness of these block-shaped members 20 is about 40 mm so that the effective thickness of the longitudinal block-shaped insulation members 20 at both sides of the gate or door leaf 6 has a total thickness of some 80 mm. In practice that means that the insulating ability of said gate or door leaf 6 is significant high.
• said longitudinal block-shaped members 20 at said first side 12 of said gate or door leaf 6 being provided with inwardly inclined side edges 22, such that when the gate or door leaf 6 is rolled up around said reel system 8 may take up a minimum of space in the reel system.
• Opposite side edges 24 of said gate or door leaf 6 are adapted to be guided in vertical side guards 26 which are provided with elongated electrical heating elements 28. Furthermore, it would be advantageously that said vertical side guards 26 communicate with upright supports in the form of vertical channels 30 leading - as a chimney - the generated heat air upwards to said reel system 8. In a simple practical manner it is hereby achieved that the formation of ice inside an overhead housing 38 at the same time may be reduced or prevented.
• said overhead housing 38 for said upper reel system 8 may be such provided with a lower flexible demountable closure leaf 32 is consisting of one or more web layers filled with a core of suitable insulation material.
• said vertical side guards 26 being provided with a laser curtain 34 extending upwards in the range of some 250 cm from the bottom of the gateway opening 4. In a rather simple manner it is hereby possible to prevent the operation of the gate or door leaf 6 when there is any form for traffic through the gate- or doorway 4.
• said rolling up mechanism may include one or more tensioning webs positioned at said first side 12 of the rolled up gate or door leaf 6 and at said opposite side 16 of the rolled up gate or door leaf 6 - as an upper web end part 36 of said gate or door leaf 6 is made without said longitudinal block-shaper members 20.
