Definitions

  • the invention discloses a sliding door that comprises at least two adjacent panels, said panels having a first and a second lateral face, said two panels extend in a first direction along which said panels are directed towards each other with one of said first and one of said second lateral faces, which two panels are hinged together by means of hinges and forming a panel section joint comprising said first and second lateral face and a hinge axis propagating near the inside surface of said door, said first lateral face comprises a front nose portion extending adjacent to the outside surface of the door as seen from the side, said second lateral face of said section joint comprises a profile attaching portion.
  • Doors of this type can be used for e.g. closing larger openings, with the door extending in a horizontal plane, above the passage, in its open condition.
  • the panels which are guided in rails on either side of the passage, are tilted, starting with the lowermost panel.
  • panels positioned adjacently to each other will pivot with respect to each other.
  • Conventionally, such overhead doors constructions are common for industrial buildings and garages.
  • a section joint for doors is disclosed.
  • Each panel which is arranged between two adjacent panels has, on one of its end faces a surface region which extends in a convex curvature, viewed in section in the direction of the hinge axis, and, on its other end face, a surface region which extends in a concave curvature, viewed in section in the direction of the hinge axis.
  • the curvatures having their centres of curvature close to the adjacent hinge axis so that a clearance region is defined by the hinge connection hinging said panels to one another, which clearance region is of a correspondingly arcuate shape in this sectional view.
  • the clearance region is, in each displacement position of the panels of the door leaf, too narrow for fingers to get caught.
  • the panels are essentially carried by hinging elements leading to that the hinging elements are carrying a substantial load. It is desirable, especially for larger industrial doors, to allow for a precise fitting and support of the door panels during assembling as well as when the door is in use, during which it may e.g. be exposed to wind loads etc.
  • US 3,941,180 discloses a panel construction in which a section joint comprising a rail having a nose portion adapted to narrowly follow a curved portion of a facing end portion of an adjacent lower panel such that in each displacement position of the panels of the door leaf, the clearance region is too narrow for fingers to get caught.
  • adjacent panels touch one another in the front lateral surface and the back lateral surface of the section joint. This in turn provides stability to the door and support between the door panels.
  • two adjacent panels cannot hinge any further than the position in which the front lateral surfaces of the panels touch each other near the outside surface of the door, in which position the panels are in line, so that the door extends in a flat plane. It may be desirable, however, for the two panels of a sliding door to pivot slightly further e.g. when a panel is moved along the guide rails and about to enter the curved part of the guide rail.
  • EP 1 072 750 presents a design that enables stability and support of panels similar to that of US 3,941,180 and in addition with the possibility to flexibly arrange for finger protection to some extent by means of a separately attachable profile. There seems to be a need for such doors to further avoid pinching of a finger, especially a finger tip, by the mouth of the clearance region between the outer walls of successive panels when the panels move towards each other during their relative movement. The issue of achieving a sliding door which is capable of providing improved finger protection, support, sealing and stability between panels of a sliding door remains to be solved.
  • the object of the present invention is to provide a sliding door that overcomes the above issues, and presents support between panels as well as enable finger pinch protection.
  • a further object of the present invention is to provide a panel section for a sliding door that allows to be adapted in order to meet various requirements without having to change the whole manufacturing process.
  • a sliding door which provides for good sealing conditions, a thorough fastening system for the hinges between panels as well as a capability to withstand various environmental conditions.
  • a sliding door comprising at least two adjacent panels, said panels having a first and a second lateral face, said two panels extend in a first direction along which said panels are directed towards each other with one of said first and one of said second lateral faces, which two panels are hinged together by means of hinges and forming a panel section joint comprising said first and second lateral face and a hinge axis propagating near the inside surface of said door, said first lateral face comprising a front nose portion extending adjacent to the outside surface of the door as seen from the side, said second lateral face of said section joint comprising a profile attaching portion, wherein attached to said profile attaching portion is a sloping profile which faces away from the hinge axis and extends obliquely in a direction away from said second lateral face towards the inside surface of the door, said sloping profile comprising a sealing member which is deformable at the outside of the door and between the two panel sections while abutting said front nose portion and
  • a section joint providing a closure towards the outside as well as finger pinch protection is presented.
  • a flexible sliding door arrangement is accomplished which sealing effect and finger pinch protecting effect may be altered into detail by solely alter the shape and/or properties of the attachable sloping profile, thereby enabling more accurate performance for each door without an immediate need for redesign of the whole panel manufacturing line.
  • the location of the seal, arranged to the sloping profile enables excellent sealing, improved finger pinch protection together with a high degree of support in the panel section.
  • Another advantage which is obtained from arranging the supporting surfaces in this way is the fact that the sealing member during closing are subjected to a pressure which is perpendicular to the supporting portions. Said pressure of the sealing member from the supporting portions during closing will deform part of the sealing member. The sealing member is forced to extend towards the outside of the section joint, during closing, while a clearance region between the lateral faces of the panels of the section joint shrinks leading to that even a finger tip is gently pushed out from the clearance region.
  • the sealing members When the door is opened, the sealing members will expand substantially in the opening direction and thus it may be opened without consequent chafing of the section joint surfaces.
  • the location of the sealing members also enables support of the front nose portion in closed condition without adding any friction to the opening movement. Due to the sealing member resilience it rather supports the opening process at the start. A further advantage is that scraping of supporting portions and the resulting noise for that matter due to metal to metal contact is avoided.
  • the supporting portions can be arranged in any suitable way and still be able to fulfil their purpose. According to the invention, and particularly for industrial doors, it is especially beneficial when they are on a plane which is perpendicular to the front and back of the sections so that the sections will assume a straight position when they are put on top of each other during mounting.
  • Another advantage which is obtained from the location of the sealing member between the supporting portion and front nose portion in the closed position is that influx of air and seepage of water into the section joint is prevented.
  • the dimension of the compressed sealing member that is present near the outside as seen in a cross section of said first direction in the closed condition of the door is less than 6 mm, preferably less than 4,0 mm and more preferably about 2 mm measured in the normal direction from the below supporting portion.
  • the sealing member is compressible.
  • the material of the flexible member is rubber or similar.
  • the sealing member has a cross section comprising an enclosed space.
  • a gap also referred to as clearance region in this text, between the lateral faces of the panels in a section joint. Due to its location on the below supporting portion the sealing member will be exposed to a minimum of friction resulting from the relational movement between panels.
  • the tip of the front nose portion is arranged to follow the upper surface of the sloping part of the sloping profile at a distance less than a fingers width, preferably less than 6 mm and more preferably less than 4,0 mm, as seen in a cross section along said first direction of said section joint during opening and closing movement of the door.
  • the upper surface of the sloping part of the sloping profile has a curved shape.
  • the upper surface of the sloping profile preferably has a smooth curved shape which transcends to a sealing member by the foot of the sloping profile.
  • said first lateral face comprises an inner nose portion arranged near the inside of the door for providing support against the second lateral face of said section joint. Furthermore, an open region is formed between the sloping profile and the inner nose portion.
  • the present invention thus allows for an open and less compact design which makes room for additional improvements in a flexible manner.
  • the hinge fastening elements protrudes through the sidewalls of the inner nose portion and into said open region.
  • the fact that the fastening elements, such as screws, bolts or similar are left with sufficient space for protruding into the open region provides for often desired additional support to the fastening of hinge elements in that the fastening elements can be held by two support walls instead of just the outer support wall.
  • an intermediate member may also be present between the inner nose portion and at least the part of the second lateral face that supports said inner nose portion.
  • the intermediate member is made of a material which is more compressible than the outer surface of the panel sections.
  • said intermediate member is a sealing member.
  • the front nose portion is arranged to closely follow the upper surface of the sloping profile during pivoting of the door panels. As long as this condition is fulfilled the exact shape of the space between the lower lateral side of the upper panel and the upper surface of the sloping profile attached to the lower panel could be selected from a variety of options in order to meet the demand for reducing finger pinching risk.
  • said first lateral face has a polygonal contour as seen in cross section of said section joint along the first direction.
  • the polygonal contour is made such that additional space between the upper surface of the sloping profile and the lower lateral side of the upper panel is achieved compared to the space defined by a distance between the nose portion and the upper surface of the lower panel during a pivoting motion.
  • the comparatively increased space generally defined by the shape of the upper panel enables a variety of options as regards shape and dimensions of attachable profiles. It is desirable for many reasons to provide for a margin as regards tolerances and smaller deformations due to e.g. impact or temperature in order to enable a smooth pivoting movement during various conditions.
  • said sloping profile is advantageously connectable with said profile attaching portion in at least two positions spaced from one another as seen in cross section of said section joint along said first direction in order to secure said sloping profile to the panel.
  • a firm attachment of the sloping profile has the advantage that the pivoting movement can be performed in relation to two mutually lateral faces in a stable manner with reduced risk for obstruction or increased friction due to dislocation etc.
  • said sloping profile is snap connectable with said profile attaching portion.
  • Such profile would be easy to replace, if desirable, in an assembled door.
  • said sloping profile is slip connectable, along said first direction, in said profile attaching portion as seen in cross section of said section joint.
  • said door is an overhead sliding door in which the panels are sliding in a path describing a transition from a vertical to a horizontal movement via a curved zone during opening and vice versa during closing.
  • sliding doors of the kind that has a curved section at a vertical distance within reach for fingers are suitably arranged in accordance with the claimed invention.
  • other door types with a need for improved finger pinch protection such as a sideways slidable door in which the panels are sliding in a path describing a transition from a first direction to a second direction via a curved zone during opening and vice versa during closing are anticipated.
  • a method of making a sliding door comprising at least two adjacent panels said panels having a first and a second lateral face, said two panels extend in a first direction along which said panels are directed towards each other with one of said first and one of said second lateral faces forming part of a panel section joint, which method comprising the step of attaching a sloping profile for finger protection, said sloping profile comprising a sealing member propagating along said first direction, to a profile attaching portion of said second lateral face and further arranging said sloping profile such that said sealing member is deformable at the outside of the door and between the two panel sections while abutting a portion of said first lateral face and a supporting portion of the section joint, when said lateral faces of the two closing panel sections during closing movement being near a closed position.
  • a method of providing a section joint having a closure towards the outside as well as finger pinch protection is presented.
  • a method for flexibly arranging a sliding door arrangement is accomplished which sealing effect and finger pinch protecting effect may be altered into detail by solely change the shape and/or properties of the attachable sloping profile, thereby enabling more accurate performance for each door without an immediate need for redesign of the whole panel manufacturing line.

  • the first lateral face 203 further describes a supporting portion by the tip 220 of the inner nose portion 217.
  • the upper part of the sub adjacent section has a second lateral face 204 and furthermore comprises a supporting portion 213 adapted to support the front nose portion 208 of the super incumbent section with a sealing member 212 in between.
  • the second lateral face 204 further describes a supporting portion for the supporting portion 220 of the inner nose portion 217.
  • the supporting surfaces are in a plane which is perpendicular to one another.
  • the supporting surfaces are placed at a large distance from one another, seen in cross section, providing stable support that ensures an aligned orientation of the sections when assembled. Further help for correct aligning of sections is given by a protruding portion of the second lateral face adjacent the inner supporting portion. The sealing by the front nose portion will provide the necessary friction for aligning the sections.
  • the second lateral face 204 comprises a profile attaching portion 210.
  • the profile attaching portion in the first embodiment consists of two grooves or rather attaching parts 224, 225 propagating along the second lateral face.
  • the first attaching part 224 is positioned towards the outside surface 209 of the door and the second attaching part 225 is positioned more towards the inside surface of the door.
  • the first attaching part 224 is shaped like a pocket with an opening towards the outside surface 209. In between the attaching parts 224, 225 the lateral face describes a ridge part. Together said parts forms the profile attaching portion 210 of said first embodiment.
  • the sloping profile 211 has a lower part which is adapted for mutual engagement with the attaching portion 210.
  • the sloping profile 211 according to the first embodiment has a protruding portion for engagement with the first attaching part 224, preferably said protruding portion is inserted in the first attaching part 224. Consequently, a second protruding portion of said sloping profile is adapted to be inserted in said second attaching part 225.
  • the attachment of said sloping profile is preferably accomplished by snap engagement.
  • the third embodiment as depicted in fig 4a also allows for the sloping profile 211 to be slipped along the attaching portion 210 for mutual engagement of the same.
  • the sloping profile 211 preferably has a substantially curved shape of the upper surface with a radius that coincides with the centre of the hinge 205.
  • a sealing member 212 is formed by the foot of the slope of the sloping profile 211 to which sealing member 212 the upper surface of the sloping profile preferably transcends smoothly with a small curved radius.
  • the smooth transition of the sloping profile 211 to the sealing member 212 will gently guide a potential finger out of the region where severe finger pinching may occur and into a region towards the outside of the door where a compressible sealing member 212 will gently push said finger, or rather finger tip, out of the section joint 206. This is further described with reference to fig 4b.
  • the sealing member 212 is compressible and furthermore adapted to be deformable such that when compressed by the closing panel sections of a section joint it is forced outwards without being held back by said panel lateral faces in order to find space. Hence, a finger, fingertip or the like will be gently pushed out from the section joint by a deformable member which in turn provides a cushioning effect at the final stage, further improving finger pinch protection.
  • the sealing member 12 is preferably made of rubber or similar material.
  • the sealing member 212 has a cross section comprising an enclosed space for achieving the desired effect, i.e. being forced outwards when compressed in order to push out fingers.
  • the tip 214 of the front nose portion 208 is arranged to follow the upper surface of the sloping part of the sloping profile 11 at a distance less than a fingers width, preferably less than 6 mm and more preferably less than 4 mm, as seen in a cross section along said first direction of said section joint 206 during opening and closing movement of the door.
  • a fingers width preferably less than 6 mm and more preferably less than 4 mm
  • the upper surface of the sloping profile extends further than the maximum pivoting angle of the section joint which may be around 70 degrees.
  • the material of the sloping profile 211 apart from the sealing member 212 is plastic or a similar material.
  • the choice of material is related to how the sloping profile is attached.
  • the overall demand is that it is stiff enough not to give in when being pushed by a finger.
  • the fastening elements 222 such as screws, bolts or similar are left with sufficient space for protruding into the open region 228 provides for often desired additional support to the fastening of the hinge elements 205 in that the fastening elements 222 (not shown) can be held by two support walls instead of just the outer support wall.
  • an intermediate member 230 is present between the inner nose portion 217 and at least the part of the second lateral face 204 that supports said inner nose portion 217 via said intermediate member 230.
  • this intermediate member 230 is arranged more towards the inside of the door than the sealing member 212 it is normally not exposed to extreme temperature changes and a stable sealing effect may be obtained at this location.
  • section joints according to the invention may be provided with various kinds of hinges without departing from the scope of protection.
  • the attachable sloping profile may be attached during manufacturing, assembling or whenever there is a need.
