Definitions

  • the present invention relates to a door opening device for opening cabinet doors, such as doors of industrial freezer or cooler cabinets, where the device at least comprises:
  • the present invention also relates to a cabinet comprising at least one chamber configured to be closed off using one or more cabinet doors mounted to a front end of the cabinet via at least one set of hinges.
  • the present invention further relates to a method of operating a door opening device arranged relative to a cabinet having at least one cabinet door, wherein the method comprises the steps of:
  • US 5622416 A discloses a dual opening device for a cabinet with two doors where the device comprises an L-shaped pedal coupled to one end of a rod which at the other end is shaped to form a lever.
  • the lever is placed between the front end of the cabinet and the door and pivots when the pedal is operated, thereby pushing the door to an open position.
  • the rod may be coupled to the pedal by means of cylindrical bearings placed on the rod or by means of a T-shaped flange bolted to the pedal.
  • the device does not comprise means for protecting the coupling during an overload of the pedal, meaning that the coupling will break or crack in the event of an overload. Furthermore, this configuration cannot be used if the space around the cabinet is limited.
  • US 2006/0137247 A1 discloses a foot operated door opening device comprising an L-shaped lever coupled to a base unit.
  • One arm is configured to act as a pedal while the other arm is configured to push the door to an open position.
  • force applied to the pedal shaped arm is transferred directly to the other arm, as they form part of the same lever element. This means that the lever arm will break off, if the pedal is overloaded. Only a limited amount force or torque can be transferred to the door, since the arms only have a length of five centimetres or less. This means that doors, such as freezer or cooler doors, will only be opened partially meaning that the user has to use his foot or hand to further open the door.
  • US 772060 A discloses a door opening device having a floor mounted base unit with pivotal L-shaped lever which is connected to a user operated wire at one end.
  • a spring element connects the base unit to a lower frame mounted unit having another pivotal lever which has a contact surface for contacting the door.
  • Another object of the invention is to provide a door operating device with a safety mechanism that protects the device if the pedal is overloaded.
  • Another object of the invention is to provide a door operating device that can be adapted to fit a left-hinged door or a right-hinged door.
  • the invention relates to a door opening device characterised in that the device further comprises a safety mechanism arranged between the first and second element for disengaging the force transferring coupling between the two elements, the safety mechanism comprises a first coupling element located on the first element and a second coupling element located on the second element, wherein the two coupling elements are configured to remain in engagement until the force exceeds a predetermined threshold, and wherein the safety mechanism is configured to be activated, when the force applied to the first element exceeds the predetermined threshold.
  • the safety mechanism is configured to disengage the mechanical coupling between the two moving elements. This prevents the engaging parts of the coupling from braking when excessive force is applied to the pedal, i.e. the first element. This allows the first element to move relative to the lever, i.e. the second element, and also the base unit so that no force is transferred between the two elements.
  • the safety mechanism may advantageously be configured so that the coupling may be engaged afterwards in a quick and simple manner.
  • the safety mechanism may define the coupling between the first and second element or be arranged at a radial distance from the first coupling and define a second coupling which allows the second element to follow the pivotal movement of the first element.
  • the base unit may comprise a mounting surface configured to be mounted to the front end of a cabinet using fastening means, such as screws, bolts, or an adhesive or adhesive layer.
  • the cabinet may be any type of an upright cabinet, including freezer or cooler cabinets, with at least one chamber configured to be closed off via one or more front end doors.
  • the base unit may comprise two end flanges where the first and second elements are arranged between these end flanges.
  • the first and second elements may be coupled to the end flanges at two respective pivot points defining a pivot line which the two elements may pivot around.
  • the pivot line may be defined by a mounting element, such as a rod or bolt, configured to extend through the first and second elements and the end flanges.
  • the mounting element may be secured relative to the base unit using fastening means, such as bolts, nuts, locking pins or the like.
  • the base unit may have a length of 10-20 cm or 14-16 cm.
  • the base unit may be made of plastic, such as polyester, metal, such as iron, steel or copper, or another suitable material.
  • a spring system such as a torsion spring or leaf spring, may be arranged relative to the second element for automatically pivoting the second element back to its initial position, when the force on the first element is removed.
  • the spring system may be coupled to both the first and second elements and/or may partly extend into a recess in one or both elements. This allows the gap between the first and second elements to be reduced so that the device forms a compact configuration.
  • the safety mechanism may be defined by the first and second coupling elements where coupling elements may form part of the first and second elements or be mounted to these using fastening means, such as bolts or screw, or adhered or welded together.
  • the first coupling element may comprise at least a first contact surface for contacting at least a second contact surface of the second coupling element.
  • the contact surfaces may be arranged in the same plane as the pivotal movement of the second element and/or in a plane defined by the pivot line or first element. This allows the coupling elements to act as a safety clutch or safety coupling limiting the maximum amount of force or torque capable of being transferred to the second element.
  • the first coupling element may be shaped as a projection and the second coupling element may be shaped as a recess, or vice versa.
  • the first coupling element may have at least one planar and/or curved contact surface where the contact surface of the second coupling element is configured to follow the contours of the first coupling element.
  • the contact surface of the first coupling element may be formed by two interconnected planar surfaces or by a concave surface. This allows the coupling elements to be forced/pushed out of engagement in the same plane as the pivotal movement of the second element and/or by offsetting the second element relative to the first element in a direction parallel to the pivot line.
  • one of the coupling elements is configured as a moveable element coupled to a spring system which in turn is coupled the first or second element, wherein the spring system is configured to apply a spring force to the moveable element for engaging the two coupling elements.
  • the safety mechanism may be configured as a spring loaded bolt arranged inside a cavity of the first element where another spring system presses the bolt towards a recess located in the second element.
  • the bolt may be shaped to form a spherical, cylindrical, triangular or square element.
  • the recess may be shaped to follow the contour of the free end of the bolt.
  • At least one planar contact surface may be arranged inside the recess for contacting at least one mating planar contact surface arranged at the free end of the bolt. This prevents the bolt from rotating inside the recess during engagement so that the second element follows the pivotal movement of the first element.
  • the contact surfaces may be placed in an angled position, e.g. in an acute angle, relative to the longitudinal direction of the recess and bolt.
  • the bolt and cavity may be arranged in, e.g. integrated to, a side surface of the first element so that they extend perpendicularly to the pivot line.
  • the bolt may be made of metal, such as copper, iron or steel, or a plastic material, such as thermoplastic.
  • the threshold value may be defined by the force of the spring system, such as the tension, compression or twisting force.
  • a single spring may be located at the bottom of the cavity or along an inner surface of the cavity for pushing the bolt out of the cavity and towards the recess.
  • One or two springs may be coupled to the bolt and the first element for pulling the bolt out of the cavity and towards the recess.
  • the bolt may be pushed partly or completely out of the recess so that the bolt may rotate inside the recess or be moved away from the recess. This allows the threshold value, i.e. the activation of the safety mechanism, to be adjusted by simply adjusting the force of the spring system.
  • the first element may be made from a single element or comprise a first housing element and a second housing element.
  • the two housing elements define the top and bottom surface of the first element and may be coupled together using a click system, female and male coupling elements or fastening means, such as bolts, screws or the like.
  • the housing elements may instead be adhered or welded together.
  • the top and/or bottom surface may comprise friction enhancing means, such as tracks, projections, a layer of rubber, or the like.
  • the first element may be made of plastic, such as polyester, metal, such as iron, steel or copper, or another suitable material.
  • At least one stopping element may be arranged relative to the cavity and may extend at least partly into the cavity for defining a stop position of the moveable element.
  • the stopping element may be a tap or another moveable element, e.g. a spring loaded bolt, arranged inside the cavity.
  • a removable element e.g. a pin or a treated bolt/screw capable of being activated by a tool, may be inserted or screwed into a cavity, e.g. a treated cavity, of the moveable element.
  • the stopping element may alternatively be shaped to act as a spring, e.g. a leaf spring or a cantilever spring with a contact surface for contacting the moveable element.
  • the spring is deformed, e.g. by applying an external pressure, when the moveable element is inserted into and removed from the cavity. This prevents the bolt from accidently being pushed or pulled out of the cavity and potentially hitting the user, when the device is assembled or disassembled.
  • the free end of the second element is configured to bend in an opposite direction relative to its pivotal movement, when force is applied to the first element, wherein the free end returns to its initial state, when the force is removed.
  • the second element may be made of at least a material having a predetermined rigid-ness or elasticity and/or have a configuration that allows the free end to bend or flex relative to its unloaded state defined by the longitudinal direction of the second element.
  • the second element may be formed as an elongated lever or arm configured to be placed between the front end of the cabinet and the cabinet door.
  • the second element may have a first contact surface for at least partly contacting a contact surface on the front end.
  • a second contact surface located at opposite side of the second element may at least partly contact a contact surface on the cabinet door.
  • the cross-sectional profile of the second element may be tapered off towards the free end.
  • the elasticity may be defined based on the elastic moduli, such as Youngs modulus, of the material allowing the free end to be moved, i.e. bend, in an angular direction to a maximum allowable position.
  • the maximum angular movement may be 1-10 degrees or 4-6 degrees.
  • the second element may be made of polycarbonate, polyurethane, polyethylene, or another suitable material. This allows the free end to bend backwards, as the second element pushes the door from its closed position towards an open position. The free end then returns to its initial position, when the force on the first element is removed. This allows the second element to apply a swiping motion on the door, causing it to open more.
  • the second element has a length of at least 10 cm.
  • the second element may have a length that is considerable longer than the length of any conventional levers.
  • the length of the second element may be greater than the length of the first element.
  • the first element may have a length of 5-20 cm or 10-15 cm.
  • the second element may have a length of 10-30 cm or 15-25 cm. This allows the second element to push the door to an open position located further away from its closed position than the conventional door opening devices, and thereby providing easier access to the chamber.
  • the first and second elements are placed in a first configuration relative to the base unit for a right-hinged door and in a second configuration for a left-hinged door.
  • the door opening device may be prepared to fit both a right-hinged door and a left-hinged door.
  • Two second coupling elements may be arranged on opposite side surface of the second element allowing it to be placed on either side of the first element during assembly/mounting.
  • the top and bottom surfaces of the first element may have the same configuration allowing it to be turned over, i.e. rotated 180 degrees around its longitudinal direction, during assembly/mounting.
  • the first coupling element or spring loaded bolt may then be arranged at a side surface of the first element.
  • the opposite side may be prepared so that the spring loaded bolt may be installed on that side, or another first coupling element or spring loaded bolt may be arranged on that side. This allows the configuration of the device to be altered by simply changing the position and/or orientation of the two elements relative to the base unit.
  • At least a part of the first element is shaped as a pedal.
  • the first element may be configured as an elongated pedal where the free end is configured to be operated by a foot or as planar element where a part of the element is configured to be operated by a foot.
  • the planar element may comprise a cut-out located in the middle so it forms an O-shaped element.
  • the pedal may be positioned so that it extends outwards from the bottom of the door. This allows the device to be mounted at or near the bottom of the cabinet so that only the part forming the pedal extends outwards from the front of the cabinet. This is desired if multiple cabinets are stacked side-by-side or the space around the cabinet is limited.
  • the pedal may be configured to extend outwards from a side surface of the door. This is desired if the space below the cabinet or door is limited.
  • the first element may have a width that at least corresponds to the width of an averaged sided foot of a human, e.g. 10-20 cm or 10-15 cm. This provides a suitable surface area for the user to safely operate device with his foot.
  • the second element may have a width of 1-3 cm or 2 cm. This allows it to be arranged relative to the peripheral edge of the cabinet so that it does not extend beyond the thickness of the cabinet walls.
  • the housing of the first element may have a height of 0.5-3 cm or 1-2 cm allowing it to have a structural strength that prevents it from bending when force is applied.
  • the invention also relates to a cabinet characterised in that at least one door opening device, as defined above, is mounted to the cabinet at an opposite side of the hinges, wherein the device at least comprises a first element configured to be operated by a user's foot, which first element is coupled to a second element positioned between the front end of the cabinet and the cabinet door, and wherein a safety mechanism is arranged between the first and second elements for disengaging the force transferring coupling, when the force applied to the first element exceeds a predetermined threshold.
  • the door opening device is well-suited to be used to open any type of an upright cabinet having a single-hinged or double-hinged door. If the door is a double-hinged door, the two door opening devices may be mounted to the cabinet, one at each side.
  • the cabinet may a domestic or industrial cabinet for storing food, vine, cigars, clothing, articles for serving food, blood, biologic samples or materials, etc.
  • the door opening device may be mounted to the cabinet at the manufacturing site or at the installation site.
  • Industrial cabinets are defined as any type of professional cabinets for professional use or self-service use.
  • Domestic cabinets are defined as any type of commercial cabinets for domestic/household use.
  • the front end of the cabinet may be prepared so that the base unit of the device can be positioned and mounted at or near a lower left or right corner.
  • the base unit may be configured so it can be mounted to the bottom of the cabinet instead.
  • the device may be assembled by first mounting the base unit to the cabinet.
  • the moveable element and the spring system of the safety mechanism may then be placed in the desired cavity and/or the first element may be positioned so that the top or bottom surface faces the door.
  • the second element may then be positioned relative to the desired side surface of the first element and/or be turned over so that the free end extends along the contact surface of the door.
  • the first and second element may then be coupled to the base unit, e.g. via the mounting rod.
  • the cabinet is an industrial freezer or cooler cabinet.
  • the invention is particularly suited for opening industrial cabinets, such as industrial freezers, refrigerators or other cooling cabinets.
  • the increased opening of the cabinet door due to the swiping effect and length of the second element allows for an easier access to the freezing or cooling chamber.
  • the foot operated device allows the user to open the cabinet even if he has no free hands thus, quicker access to the cabinet. This may reduce the total time for which the door is open, which is an issue for professional cabinets since the stored items typically has to be kept at optimal conditions constantly.
  • the invention further relates to a method of operating a door opening device characterised in that the method further comprises at least one of the following steps:
  • the door opening device may be operated in the same manner as a conventional door opening device, when the force applied is below the predetermined threshold.
  • the integrated safe mechanism disengages the coupling elements thus, moving the moveable element out of the recess, when the applied force exceeds the threshold. This stops the transfer of forces between the first and second elements and allows the first element to move relative to the second element, or vice versa.
  • the device may be reset by simply moving or pivoting the first element back towards the second element thus, placing the moveable element in the recess again. This protects the device in the event of an overload and prevents the coupling from breaking.
  • Fig. 1 shows an exploded view of a door opening device 1 according to the invention.
  • the door opening device 1 comprises a base unit 2 having a mounting surface 3 configured to be mounted to a front end 4 of a cabinet 5.
