Description

[Technical Field]

[0001] The present disclosure relates to the field of laboratory equipment, in which it relates to door hinges for laboratory equipment doors, laboratory equipment doors, laboratory equipment, laboratory equipment door assembly kits, and methods for assembling laboratory equipment door assembly kits. [Background technology]

[0002] In diagnostic laboratories, automated laboratory equipment, such as pre-analytical, analytical, or post-analytical devices, are used for various sample processing steps to generate accurate and reliable test results that represent important information for physicians.

[0003] Typically, the interior of such laboratory equipment contains sample processing devices, consumables, sample vessels, reagent containers, etc. To protect the interior from environmental factors (e.g., temperature, humidity, dust, etc.) and / or to prevent unwanted access to the interior of the laboratory equipment, the interior is shielded from the environment around the laboratory equipment by a housing. However, access to the interior is sometimes required for manual or automated loading / unloading of consumables, sample vessels, and reagent containers, or for maintenance activities on the sample processing device. Therefore, the housing includes an entry or gate that can be closed and opened by moving a laboratory equipment door between a closed and an open position.

[0004] Typically, laboratory equipment doors include one or more door hinges that pivotally connect a door leaf or hood to a door frame, allowing the door leaf or hood to move between a closed position and an open position. An actuator or spring mechanism may be used to facilitate movement of the door leaf or hood. For example, EP3290926 (Patent Document 1) discloses a laboratory equipment having a housing including a frame on which a hood is pivotally mounted. The housing includes a gas spring mounted on the hood and frame to facilitate pivoting movement of the hood. However, such a structure requires additional space for the gas spring and only allows the door leaf to pivot to a limited angle. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] European Patent Application Publication No. 3290926 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, there is a need for a compact door hinge that allows for high and flexible movement of the door leaf or hood, thereby better serving the needs of laboratory equipment. [Means for solving the problem]

[0007] The present disclosure is directed to door hinges for laboratory equipment doors, laboratory equipment doors, laboratory equipment, laboratory equipment door assembly kits, and methods for assembling laboratory equipment door assembly kits.

[0011] The present disclosure further relates to a laboratory equipment door assembly kit including a door frame, a door hinge as described herein, and a door leaf. The door leaf or door frame includes a mounting element configured to mount a hollow body. If the door leaf includes the mounting element, the door frame includes a mounting structure. Alternatively, if the door frame includes the mounting element, the door leaf includes a mounting structure. The mounting structure is configured to mount a linear guide element. The mounting structure includes a fixing plate including a first side, a second side, an elongated slot, and a fixing position. The elongated slot is configured to insert the linear guide element into the fixing position.

The elastic member can build up tension when the linear guide element moves in the third direction. The mounting structure further includes a locking recess configured to lock the linear guide element. The elastic member can release its tension when the linear guide element is in the locked position. The linear guide element is movable in a fourth direction when the elastic member releases its tension. The linear guide element is movable into the locking recess when the linear guide element moves in the fourth direction. The support element of the linear guide element can press against the second side of the locking plate when the linear guide element moves in the fourth direction.

[0013] (Detailed explanation) The present disclosure relates to a door hinge for a laboratory equipment door, the door hinge including a hollow body having a first longitudinal axis. The hollow body includes a curved sidewall. The curved sidewall includes a track. At least a portion of the track is inclined relative to the first longitudinal axis. The door hinge for the laboratory equipment door further includes a linear guide element having a second longitudinal axis parallel to the first longitudinal axis. At least a portion of the linear guide element is disposed within the hollow body. The linear guide element and the hollow body are rotatable relative to each other. The door hinge for the laboratory equipment door further includes a body including a protruding pin. The body is movably attached to the linear guide element, such that the body is movable in two opposite directions along the second longitudinal axis, and the protruding pin is movable on the track. Therefore, movement of the body including the protruding pin is guided by the linear guide element and the track of the hollow body. As a result, linear movement of the body is converted into rotation between the linear guide element and the hollow body. The door hinge further includes a force generating device configured to exert a force on the body to move the body in a first of two opposite directions, the force generating device being an elastic member connecting the linear guide element and the body, where the force is a tension relief of the elastic member.

[0014] As used herein, the term "laboratory instrument door" refers to an assembly including a door frame, a door hinge, and a door leaf, as further described below.

[0015] As used herein, the term "door hinge" refers to a device that allows a door leaf to pivot or rotate on an axis of rotation when opening or closing. If a hollow body is mounted on the door leaf, the axis of rotation of the door leaf is determined by a first longitudinal axis. If a linear guide element is mounted on the door leaf, the axis of rotation of the door leaf is determined by a second longitudinal axis. In one embodiment, the first and second longitudinal axes are concentric or coaxial. As a result, the axis of rotation of the door leaf is determined by the first and second longitudinal axes. In one embodiment, the first and second longitudinal axes are vertical. Thus, the door leaf can be opened or closed by horizontal rotation of the door leaf, for example, to open or close a conventional door leaf. In an alternative embodiment, the first and second longitudinal axes are horizontal. Thus, the door leaf can be opened or closed by vertical rotation of the door leaf, for example, to open or close an equipment hood.

[0016] As used herein, the term "door leaf" refers to a barrier that closes or opens an entry or gate to the interior of a piece of laboratory equipment. Thus, the door leaf can be rotated from a closed position that prevents access to the interior of the laboratory equipment to an open position that exposes and allows access to the interior of the laboratory equipment, or vice versa. The door leaf may be a conventional door leaf that fits onto a piece of laboratory equipment or a laboratory equipment hood.

[0017] In one embodiment, the hollow body has a horizontal cross-section, and the first longitudinal axis is perpendicular to and located at the midpoint of the horizontal cross-section. In one embodiment, the hollow body is a pipe. Thus, the hollow body includes one circular sidewall, and the entire sidewall is curved. In another embodiment, the hollow body includes multiple sidewalls that form a profile, and at least one of the multiple sidewalls is a curved sidewall. The term "profile," as used herein, refers to an elongated structural member. For example, the hollow body includes four sidewalls that form a cubical profile, where at least one of the four sidewalls is a curved sidewall. The hollow body includes two opposing ends, such as a top end and a bottom end, or a left end and a right end. In one embodiment, one or both of the two opposing ends are open. For example, the hollow body includes an open top end and / or an open bottom end. In one embodiment, the hollow body is a cube or rectangular prism with a cylindrical borehole. This is parallel to the first longitudinal axis and forms a curved sidewall.

[0018] As used herein, the term "track" refers to a guide structure consisting of a curved sidewall for guiding the movement of the protruding pin of the body. The track extends along a defined angle arc of the curved sidewall. The defined angle arc of the curved sidewall can define the maximum rotation angle between the hollow body and the linear guide element. If the hollow body is a pipe and has a circular cross section, the track extends along a defined circular arc. This circular arc can define the maximum rotation angle between the hollow body and the linear guide element. For example, if the angle arc or circular arc is 45 degrees, the hollow body and the linear guide element can rotate 45 degrees relative to each other. Because at least a portion of the linear guide element is disposed within the hollow body, the space requirement for the hinge is independent of the maximum rotation angle between the hollow body and the linear guide element. As a result, door hinges for laboratory equipment can be constructed very compactly.

[0019] In one embodiment, the track comprises an elongated through-hole in the curved sidewall. In another embodiment, the curved sidewall comprises an interior surface and the track is an elongated recess or groove in the interior surface. Such recess or groove allows 360-degree rotation of the linear guide element and hollow body relative to one another.

[0020] As used herein, the term "inclined" means that at least a portion of the track is oriented neither parallel nor perpendicular to the first longitudinal axis. In one embodiment, a surface normal of the track and a vector parallel to the first longitudinal axis subtend an inclination angle α that is neither 0 nor 90 degrees. In one embodiment, the inclination angle α is between 45 and 80 degrees, optionally between 45 and 70 degrees, optionally between 45 and 60 degrees, or optionally between 45 and 50 degrees. In a more specific embodiment, the inclination angle α is 45 degrees. The degree of inclination of the track, or inclination angle α, determines how much force is required to open or close a loaded door leaf and / or how quickly the loaded door leaf can open or close.

[0021] As used herein, the term "linear guiding element" refers to a device adapted to guide a door hinge body in two opposite directions along a second longitudinal axis. In one embodiment, the linear guiding element has a horizontal cross section, and the second longitudinal axis is perpendicular to and located at the midpoint of the horizontal cross section. In one embodiment, the linear guiding element includes a sidewall. In one embodiment, the linear guiding element is an additional pipe. Thus, the linear guiding element includes one additional circular sidewall. In another embodiment, the linear guiding element is a rectangular plate including sidewalls. In another embodiment, the linear guiding element includes multiple sidewalls that form a profile. For example, the linear guiding element includes four sidewalls that form a cubic-shaped profile. In a more specific embodiment, one or more, but not all, of the multiple sidewalls are open sidewalls. The linear guiding element includes two opposing ends, such as an upper end and a lower end, or a left end and a right end. In one embodiment, one or both of the two opposing ends are closed ends, for example, the linear guide element includes a closed upper end and / or a closed lower end.

[0022] In one embodiment, the ejector pin is a lateral protrusion of the body. The linear guide element comprises a linear through-hole. The linear through-hole is parallel to the second longitudinal axis and adapted to guide the ejector pin. In one embodiment, the linear through-hole is configured to guide the ejector pin in two opposite directions along the second longitudinal axis. Thus, movement of the body including the ejector pin is simultaneously guided by the linear through-hole and the track, causing rotation of the hollow body and the linear guide element relative to each other. In one embodiment, a side wall of the linear guide element comprises a linear through-hole. For example, if the linear guide element is a further pipe, a side wall of the further pipe comprises a linear through-hole.

[0023] In one embodiment, the linear guide element includes a support element adapted to mount the linear guide element on the door frame or door leaf. In a more specific embodiment, the support element includes a plate perpendicular to the second longitudinal axis. In one embodiment, the support element includes a bearing. The bearing may improve rotation of the hollow body and the linear guide element relative to each other.

[0024] In one embodiment, the hollow body includes a further support element adapted to movably mount the hollow body on the linear guide element, hi a more specific embodiment, the further support element includes a plate surrounding the hollow body and perpendicular to the first longitudinal axis.

[0025] In one embodiment, the length of the linear guide element is greater than the length of the hollow body, so that the linear guide element protrudes from the hollow body. For example, if the hollow body is a pipe and the linear guide element is a further pipe, the length of the pipe is less than the length of the further pipe, so that the further pipe protrudes from the pipe.

[0026] In one embodiment, the body is movably and non-rotatably attached to the linear guide element. In one embodiment, the body includes two ends. In one embodiment, the body is a piston and the protruding pin is a lateral protrusion of the piston. The piston is movably attached to the linear guide element. In a more specific embodiment, the piston has a cylindrical shape. For example, if the linear guide element is a further pipe, the piston is cylindrical and is movably mounted within the further pipe.

[0027] In one embodiment, the body includes an additional protruding pin. The linear guide element includes an additional linear through-hole. The additional linear through-hole is parallel to the second longitudinal axis and adapted to guide the additional protruding pin. In one embodiment, the additional linear through-hole is adapted to guide the additional protruding pin in two opposite directions along the second longitudinal axis. In one embodiment, the protruding pin and the additional protruding pin are located opposite each other. The linear through-hole and the additional linear through-hole are located opposite each other. For example, if the linear guide element is an additional pipe, a side wall of the additional pipe also includes an additional linear through-hole. Or, if the linear guide element includes multiple side walls forming a cubic profile, the side wall including the linear through-hole and the side wall including the additional linear through-hole are located opposite each other.

[0028] In one embodiment, the hollow body, linear guide elements, and / or body including the protruding pins are three-dimensional printed products. The term "3D printing product," as used herein, refers to a solid product made through a three-dimensional printing process. Three-dimensional printers can produce substantially freely formable hollow bodies, linear guide elements, and / or bodies including the protruding pins from filaments made of thermoplastic polymers, duroplastic polymers, metals, alloys, sintered metals, or sintered alloys.

[0029] In one embodiment, the door hinge further includes a force-generating device configured to exert a force on the body to move the body in a first of two opposing directions. In a specific embodiment, the force-generating device is provided by the body, and the force is determined by the weight of the body. In another specific embodiment, the force-generating device is a weight piece attached to the body, and the force is determined by the weight of the weight piece. In another specific embodiment, the force-generating device is an elastic member connecting the linear guide element and the body. The force is tension relief of the elastic member. In a more specific embodiment, the elastic member is a spring. In a more specific embodiment, the spring is a linear spring. The linear spring connects one end of the body and one closed end of the linear guide element. For example, the linear spring connects an upper end of the body and the closed upper end of the linear guide element. Thus, the linear spring is located between the body and the closed upper end of the linear guide element. The force-generating device can facilitate or automate the rotation between the linear guide element and the hollow body relative to each other.

[0030] In a specific embodiment, the strain relief pushes the body in a first of two opposite directions. In an alternative specific embodiment, the strain relief pulls the body in a first of two opposite directions.

[0031] In one embodiment, tension in the elastic member is built up when the body moves in a second direction opposite the first direction, as further described below.

[0032] In one embodiment, the track includes a first section, a moving section, and a second section. The moving section connects the first section and the second section. The moving section is tilted relative to the first longitudinal axis. In one embodiment, a surface normal of the moving section and a vector parallel to the first longitudinal axis subtend a tilt angle α that is neither 0 nor 90 degrees. In one embodiment, the tilt angle α is between 45 and 80 degrees, optionally between 45 and 70 degrees, optionally between 45 and 60 degrees, or optionally between 45 and 50 degrees. In a more specific embodiment, the tilt angle is 45 degrees.

[0033] In one embodiment, the ejector pin is movable between the first and second sections as the body moves in two opposite directions, the hollow body is rotatable about a first longitudinal axis in two opposite rotational directions as the ejector pin moves between the first and second sections, or the linear guide element and the body are rotatable about a second longitudinal axis in two opposite rotational directions as the ejector pin moves between the first and second sections.

[0034] In one embodiment, the body is movable in two opposite first directions along the second longitudinal axis, e.g., a force-generating device exerts a force on the body to move the body in the first direction, as described above. The ejector pin is movable from the first section to the second section as the body moves in the first direction. The hollow body is rotatable in a first of two opposite rotational directions about the first longitudinal axis as the ejector pin moves from the first section to the second section. Alternatively, the linear guide element and the body are rotatable in a first of two opposite rotational directions about the second longitudinal axis as the ejector pin moves from the first section to the second section. The first rotational direction of the hollow body is opposite to the first rotational direction of the linear guide element and the body.

[0035] In one embodiment, the hollow body is rotatable in two opposing second rotational directions about the first longitudinal axis, or the linear guide element and the body are rotatable in two opposing second rotational directions about the second longitudinal axis. The ejector pin is movable from the second section toward the first section when the hollow body rotates in two opposing second rotational directions about the first longitudinal axis, or the linear guide element and the body are rotated in two opposing second rotational directions about the second longitudinal axis. The body is movable in two opposing second directions along the second longitudinal axis when the ejector pin moves from the second section toward the first section. The second rotational direction of the hollow body is opposite to the second rotational direction of the linear guide element and the body.

[0036] In one embodiment, the hollow body is rotatable in a first rotational direction about a first longitudinal axis to open or close a door leaf of a laboratory equipment door when the hollow body is mounted on the door leaf and the linear guide element is mounted on a door frame of the laboratory equipment door. In an alternative embodiment, the linear guide element and the body are rotatable in a first rotational direction about a second longitudinal axis to open or close a door leaf of a laboratory equipment door when the linear guide element is mounted on the door leaf and the hollow body is mounted on a door frame of the laboratory equipment door.

[0037] In one embodiment, tension in the elastic member is built up when the body moves in two opposite second directions. The body is movable in the second direction by moving the ejector pin from the second section toward the first section. The ejector pin is movable from the second section toward the first section by rotating the hollow body in a second rotational direction about the first longitudinal axis or by rotating the linear guide element together with the body in a second rotational direction about the second longitudinal axis.

[0038] In one embodiment, the hollow body is rotatable in a second rotational direction by moving the door leaf on which the hollow body is mounted from an open position to a closed position or from a closed position to an open position. In an alternative embodiment, the linear guide element, together with the body, is rotatable in a second rotational direction by moving the door leaf on which the linear guide element is mounted from an open position to a closed position or from a closed position to an open position. In one embodiment, the door leaf is manually or automatically movable or pivotable. For example, an operator can open or close the door by moving or pivoting the door leaf from a closed position to an open position or from an open position to a closed position. In another embodiment, an actuated object presses or pushes the door leaf to move or pivot the door leaf from an open position to a closed position or from a closed position to an open position. In another embodiment, an actuator moves or pivots the door leaf from an open position to a closed position or from a closed position to an open position.

[0039] In one embodiment, the rotation speed of the hollow body in the first rotation direction, or of the linear guide element and the body in the first rotation direction, is determined by the force generated by the force-generating device and by the degree of inclination or inclination angle α of the part of the track that is inclined with respect to the first longitudinal axis. Thus, different rotation speeds can be realized by assuming a constant force and adapting the degree of inclination / inclination angle α, or by assuming a constant degree of inclination / inclination angle α and adapting the force. For example, springs with different spring strengths can be used to increase or decrease the rotation speed.

[0040] In one embodiment, the second section is oriented perpendicular to the first longitudinal axis, such that the ejector pin is stopped and held in the second section. In one embodiment, the surface normal of the second section and a vector parallel to the first longitudinal axis are parallel to each other, such that the ejector pin is stopped and held in the second section. As a result, the body is stopped in its position relative to the hollow body during its linear movement in the first direction, and rotation between the hollow body, the linear guide element, and the body relative to each other is stopped. For example, the ejector pin is stopped and held in the second section when the body moves in the first direction and the hollow body, or the linear guide element together with the body, rotates in a first rotational direction about the first longitudinal axis.

[0041] In one embodiment, the first section is oriented perpendicular to the first longitudinal axis, such that the ejector pin is retained in the first section. In one embodiment, the surface normal of the first section and a vector parallel to the first longitudinal axis are parallel to each other, such that the ejector pin is retained in the first section. As a result, the body is retained in its position relative to the hollow body during its linear movement in the second direction, and rotation between the hollow body, the linear guide element, and the body is restricted. For example, the ejector pin is retained in the first section when the body moves in the second direction and the hollow body, or the linear guide element together with the body, rotates in the second rotational direction about the first longitudinal axis.

[0042] In one embodiment, the protruding pin held by the first section is movable from the first section to the moving section by initial rotation of the hollow body in a first rotational direction. The initial rotation of the hollow body in the first rotational direction comprises moving or pivoting a door leaf on which the hollow body is mounted. In an alternative embodiment, the protruding pin held by the first section is movable from the first section to the moving section by initial rotation of the linear guide element with the body in the first rotational direction. The initial rotation of the linear guide element with the body in the first rotational direction comprises moving or pivoting a door leaf on which the linear guide element is mounted. In one embodiment, the door leaf is movable or pivotable manually or automatically. For example, an operator can move or pivot the door leaf. In another embodiment, a driven object presses or pushes the door leaf to move or pivot the door leaf. In another embodiment, an actuator moves or pivots the door leaf.

[0043] In one embodiment, the track includes a third section. The moving section includes a first part and a second part. The first part of the moving section connects the first and third sections of the track, and the second part of the moving section connects the third and second sections of the track. The third section is oriented perpendicular to the first longitudinal axis, such that the ejector pin is stopped and held in the third section. In one embodiment, the surface normal of the third section and a vector parallel to the first longitudinal axis are parallel to each other, such that the ejector pin is stopped and held in the third section. As a result, the body is stopped in its linear movement relative to the hollow body, and rotation between the hollow body, the linear guide element, and the body relative to each other is prevented. For example, as the ejector pin moves on the first part of the moving section toward the third section, the ejector pin is stopped and held in the third section of the track. In one embodiment, the protruding pin carried by the third section of the track is movable from the third section to the second part of the moving section by further initial rotation of the hollow body in the first rotational direction for further movement toward the second section. Further initial rotation of the hollow body in the first rotational direction comprises moving or pivoting a door leaf on which the hollow body is mounted. In an alternative embodiment, the protruding pin carried by the third section of the track is movable from the third section to the second part of the moving section by further initial rotation of the linear guide element with the body in the first rotational direction for further movement toward the second section. Further initial rotation of the linear guide element with the body in the first rotational direction comprises moving or pivoting a door on which the linear guide element is mounted. In one embodiment, the door leaf is movable or pivotable manually or automatically. For example, an operator can move or pivot the door leaf. In another embodiment, the actuated object presses or pushes against the door leaf to move or pivot the door leaf. In another embodiment, an actuator moves or pivots the door leaf.

[0044] In one embodiment, a surface normal of the first part of the movement section and a vector parallel to the first longitudinal axis subtend a tilt angle α that is neither 0 nor 90 degrees, and a surface normal of the second part of the movement section and a vector parallel to the first longitudinal axis subtend a tilt angle β that is neither 0 nor 90 degrees. In one embodiment, tilt angle α and tilt angle β are the same or different. In one embodiment, tilt angle α is between 45 and 80 degrees, optionally between 45 and 70 degrees, optionally between 45 and 60 degrees, or optionally between 50 and 40 degrees, and tilt angle β is between 45 and 80 degrees, optionally between 45 and 70 degrees, optionally between 45 and 60 degrees, or optionally between 45 and 50 degrees. In one embodiment, tilt angle α is between 45 and 80 degrees, optionally between 45 and 70 degrees, optionally between 45 and 60 degrees, or optionally between 45 and 50 degrees, and tilt angle β is between −45 and −80 degrees, optionally between −45 and −70 degrees, optionally between −45 and −60 degrees, or optionally between −45 and −50 degrees. In a more specific embodiment, tilt angle α and tilt angle β are 45 degrees. In another more specific embodiment, tilt angle α is 45 degrees and tilt angle β is −45 degrees.

[0045] In one embodiment, the linear guide element protrudes beyond the hollow body. The linear guide element is movably mounted to the hollow body, and when the protruding pin is held on the first section, the second section, or the third section of the track, the linear guide element is movable along the first longitudinal axis in a third direction and a fourth direction opposite the third direction. For example, the linear guide element is movable in the third direction when an additional force is exerted on the linear guide element, thereby creating tension on the resilient element. The linear guide element is movable in the fourth direction when the created tension is released. This embodiment may be suitable for assembling a laboratory equipment door assembly kit without using fastening elements such as screws or bolts, as described further below.

[0046] The present disclosure also relates to a laboratory equipment door including a door frame, a door hinge as described herein, and a door leaf. The linear guide element or hollow body is mounted on the door frame. If the linear guide element is mounted on the door frame, the hollow body is mounted on the door leaf. If the hollow body is mounted on the door frame, the linear guide element is mounted on the door leaf.

[0047] In one embodiment, the door leaf or the door frame includes a mounting element configured to mount the hollow body. If the door leaf includes the mounting element, the door frame includes a mounting structure configured to mount the linear guide element. Alternatively, if the door frame includes the mounting element, the door leaf includes the mounting structure. In one embodiment, the mounting element is a fastening hole into which the hollow body can be inserted and fixed. Alternatively, the mounting structure is a platform onto which the linear guide element can be mounted, for example, via a support element and a screw or bolt.

[0048] In one embodiment, the door leaf is movable or pivotable between a closed position and an open position. The door leaf is movable or pivotable to the closed or open position when the body moves in a first direction. In one embodiment, the angle between the closed and open positions of the door leaf is defined by two endpoints of an angular or circular arc of the curved sidewall over which the track extends. For example, the track extends over a 45-degree angular or circular arc of the curved side. The angle between the open and closed positions of the door leaf is 45 degrees.

[0049] In one embodiment, when the door leaf is in the open position, the protruding pin is located in the first section, and when the door leaf is in the closed position, the protruding pin is located in the second section. In another embodiment, when the door leaf is in the closed position, the pin is located in the first section, and when the door leaf is in the open position, the pin is located in the second section.

[0050] In one embodiment, the door frame is configured to stop the door leaf when the body moves in a first direction, such that when the door frame stops the door leaf, the protruding pin is stopped on the moving section. When the protruding pin is stopped on the tilted moving section, the force on the body to move the body in the first direction presses the door leaf toward the door frame. Thus, the door is well maintained in the closed position. The force acting on the body eliminates the need for an additional locking mechanism to maintain the door in the closed position. In one embodiment, the angle between the closed and open positions of the door leaf is less than the angular or circular arc of the curved sidewall over which the track extends. For example, the track extends over a 50-degree angular or circular arc of the curved side. The angle between the open and closed positions of the door leaf is only 45 degrees.

[0051] The present disclosure further relates to a laboratory instrument including a laboratory instrument door as described herein and a housing, wherein the door frame is mounted on the housing or the door frame is included in the housing.

[0059] FIGS. 1A-1C illustrate an embodiment of a door hinge 10 for a laboratory equipment door 50. As shown in FIGS. 1A and 1B, the door hinge 10 includes a hollow body 14 having a first longitudinal axis 16. The hollow body 14 includes a curved sidewall 18. The curved sidewall 18 includes a track 20, which is only partially visible in FIGS. 1A and 1B. At least a portion of the track 20 is inclined relative to the first longitudinal axis 16, as shown in FIG. 3. As shown in FIGS. 1A and 1C, the door hinge 10 further includes a linear guide element 22 having a second longitudinal axis 24 parallel to the first longitudinal axis 16. In the illustrated embodiment, the first longitudinal axis (16) and the second longitudinal axis (24) are concentric or coaxial. At least a portion of the linear guide element (22) is disposed within the hollow body (14), as shown in FIG. 1A. The linear guide element (22) and the hollow body (14) are rotatable relative to each other, as indicated by the two opposing arrows. As shown in FIGS. 1C and 2A, the door hinge (10) further includes a body (26) including a protruding pin (28). Only the protruding pin (28) is visible in FIG. 1A. The body (26) is movably attached to the linear guide element (22), such that the body (26) is movable in two opposite directions (32, 33) along the second longitudinal axis (24), while the protruding pin (28) is movable on a track (20, not shown). In the illustrated embodiment, the hollow body 14 is a pipe, and the linear guide element 22 is a further pipe. The linear guide element 22 shown includes a support element 48 adapted to mount the linear guide element 22 on a door frame 52 or door leaf 54, as shown in FIG. 4 . The hollow body 14 shown includes a further support element 49 adapted to mount the hollow body 14 on the linear guide element 22. In FIG. 1B , only the hollow body 14 of the door hinge 10 is shown. The hollow body 14 includes a first longitudinal axis 16, a curved sidewall 18, and a further support element 49. The hollow body further includes a track 20.This can only be seen in part in Figure 1(B). Figure 1(C) shows only the linear guide element (22) and the body (26) including the protruding pin (28). The body (26) is movably attached to the linear guide element (22), allowing the body (26) to move in two opposite directions (32, 33) along the second longitudinal axis (24), as indicated by the opposing linear arrows in Figure 1(C). As further shown in Figure 1(C), the protruding pin (28) is a lateral protrusion of the body (26). The linear guide element (22) includes a linear through-hole (34). The linear through-hole (34) is parallel to the second longitudinal axis (24) and is adapted to guide the protruding pin (28) in the two opposite directions (32, 33). The illustrated support element 48 for the linear guide element 22 includes a bearing 47 that improves the rotation of the hollow body 14 and the linear guide element 22 relative to one another. As further shown in FIGS. 1A and 1C, the door hinge 10 includes a force-generating device 30 configured to exert a force on the body 26 to move the body 26 in a first direction 32 of two opposing directions 32, 33. In the illustrated embodiment, the force-generating device 30 is a resilient member 31, specifically a linear spring, that connects the closed upper end of the linear guide element 22 to the upper end of the body 26. Thus, the resilient member 31 is positioned between the body 26 and the closed upper end of the linear guide element 22.

[0060] Figures 2(A)-2(B) show the same body 26 including the protruding pin 28 and linear guide element 22 as shown in Figures 1(A) and 1(C). In Figure 2(A), only the body 26 including the protruding pin 28 is shown. In the embodiment shown, the body 26 includes an additional protruding pin 29. The protruding pin 28 and the additional protruding pin 29 are located opposite each other. In Figure 2(B), only the linear guide element 22 is shown with its second longitudinal axis 24, linear through-hole 34, and support element 48. In the embodiment shown, the linear guide element 22 includes an additional linear through-hole 35. The further linear through-hole (35) is parallel to the second longitudinal axis (24) and is adapted to guide the further ejector pin (29) in two opposite directions (32, 33) along the second longitudinal axis (24). The further linear through-hole (35) shown here is located opposite the linear through-hole (34). Guiding the two ejector pins (28, 29) of the body (26) by the two linear through-holes (34, 35) improves guiding of the body (26) in the two opposite directions (32, 33).

[0061] Figures 3(A) through 3(D) depict an embodiment of a hollow body 14 and a track 20. Figure 3(A) shows a perspective view of a cross section of the hollow body 14 with its first longitudinal axis 16 and curved sidewall 18, as shown in Figures 1(A) and 1(B). Figure 3(B) shows a side view of the cross section of the hollow body 14, as shown in Figure 3(A). As shown in Figures 3(A) and 3(B), the curved sidewall 18 includes a track 20 along which an ejector pin 28 is movable. In the illustrated embodiment, the track 20 is an elongated recess or groove in the interior surface of the curved sidewall 18 and includes a first section 36, a moving section 38, and a second section 40. The moving section 38 connects the first section 36 and the second section 40. The moving section 38 is inclined relative to the first longitudinal axis 16. As shown in FIG. 3B, the surface normal 39 of the moving section 38 and the vector 17 parallel to the first longitudinal axis 16 form an inclination angle α 43 that is neither 0 nor 90 degrees. In the illustrated embodiment, the inclination angle α is 50 degrees. The ejector pin 28 is movable from the first section 36 toward the second section 40 when the body 26 moves in the first direction 32. Thus, the movement of the ejector pin 28, guided by the track 20 and the linear through-hole 34, causes the hollow body 14 and the linear guide element 22 to rotate relative to each other. For example, movement of ejector pin 28 from first section 36 to second section 40 causes rotation of hollow body 14 in a first rotational direction about first longitudinal axis 16, or causes rotation of linear guide element 22 and body 28 in a first rotational direction about second longitudinal axis 24. As further shown in FIG. 3B, second section 40 is oriented perpendicular to first longitudinal axis 16 such that ejector pin 28 is stopped and held in second section 40 as body 26 moves in first direction 32.The surface normal 41 of the second section 40 and a vector 17 parallel to the first longitudinal axis 17 are parallel to each other, such that when the body 28 moves in a first direction 32, the ejector pin is stopped and held in the second section 40. The second section 40 may define an open or closed position for a door leaf 54 of the laboratory equipment door 50. The first section 36 shown here is also oriented perpendicular to the first longitudinal axis 16, such that when the body 28 moves in a second direction 33 opposite the first direction 32, the ejector pin 28 is stopped and held in the first section 36. The surface normal 37 of the first section 36 and the vector 17 parallel to the first longitudinal axis 17 are parallel to each other, such that when the body 28 moves in a second direction 33 opposite the first direction 32, the protruding pin is stopped and held in the first section 36. The first section 36 can define the closed or open position of the door leaf 54 of the laboratory equipment door 50. Figure 3(C) shows a schematic side view of a cross section of a further embodiment of a hollow body 14. The hollow body 14 shown here includes a track 20 having a third section 42. The moving section 38 includes a first part 44 and a second part 46. A first part 44 of the moving section 38 connects the first section 36 and the third section 42 of the track 20. A second part 46 of the moving section 38 connects the third section 42 and the second section 40 of the track 20. The third section 42 is oriented perpendicular to the first longitudinal axis 16 such that the protruding pin 28 is stopped and retained in the third section 42 when the body 28 moves in either the first direction 32 or the second direction 33. A surface normal (not shown) of the third section (42) and a vector (not shown) parallel to the first longitudinal axis (16) are parallel to each other, so that when the body (28) moves in the first direction (32) or the second direction (33), the protruding pin (28) is stopped and held in the third section (42).Thus, the third section 40 can define an intermediate position between the open and closed positions of the door leaf 54 of the laboratory equipment door 50. In FIG. 3C, the first and second parts 44, 46 of the moving section 38 have the same tilt angle relative to the first longitudinal axis 16. The surface normal of the first part 44 of the moving section 38 and a vector parallel to the first longitudinal axis 16 enclose a tilt angle α (43). The surface normal of the second part 46 of the moving section 38 and a vector parallel to the first longitudinal axis 16 enclose a tilt angle β (45). The tilt angle α (43) and the tilt β (45) are the same in FIG. 3C. However, the first section 36, the second section 40, and the third section 42 may be arranged such that the first part 44 of the moving section 38 has a positive tilt angle α 43 and the second part 46 of the moving section 38 has a negative tilt angle β 45, as shown in Figure 3(D). This arrangement of the track 20 may be suitable for moving the door leaf 54 from one closed position to two different open positions, or from one open position to two different closed positions.

[0062] Figures 4(A) and 4(B) show an embodiment of a laboratory equipment door 50. The laboratory door 50 shown in Figure 4(A) includes a door frame 52, a door hinge 10 as shown in Figure 1(A), and a door leaf 54. In the illustrated embodiment, a linear guide element 22 is mounted on the door frame 52 via a support element 48. A hollow body 14 is mounted on the door leaf 54 and on the linear guide element 22 via an additional support element 49. The hollow body 14 is mounted on the door leaf 54 via a mounting element 66. The door leaf 54 includes a mounting element 66 in the form of a fastening hole into which the hollow body 14 can be inserted and secured. Figure 4(B) shows a laboratory equipment door 55 without a door leaf 54. In the embodiment shown, the support element (48) rests by means of screws (53) on a resting structure (68) in the form of a platform (55) of the door frame (52).

[0063] FIG. 5 shows a schematic side view of an embodiment of laboratory equipment 60. Laboratory equipment 60 includes laboratory equipment door 50, as shown in FIG. 4, and housing 62. In the example shown, door frame 52 is mounted on housing 62, with door leaf 54 in an open position. Door leaf 54 is mounted on door frame 52 by two door hinges 10. However, door leaf 52 can be mounted using one door hinge 10 or more than two door hinges 10. It is also possible to use a combination of door hinges 10 as described herein and conventional door hinges to mount door leaf 54 on door frame 52.

[0064] Figures 6(A) and 6(B) show schematic side views of a cross section of a door hinge 10 for a laboratory equipment door 50, such as that shown in Figure 1(A). As shown in Figure 6(A), the door hinge 10 includes a linear guide element 22 that protrudes beyond the hollow body 14. An elongated pin 28 is supported on a second section 40 that is perpendicular to the first longitudinal axis 16. The linear guide element 22 is movably mounted to the hollow body 14 and is movable along the first longitudinal axis 16 in a third direction 56, as indicated by the arrow in Figure 6(A). For example, the linear guide element 22 can be moved in the third direction 56 by applying an additional force to the upper end of the linear guide element 22. When the ejector pin 28 is held on the first section 36 or the third section 40 (not shown) of the track 20, which are perpendicular to the first longitudinal axis 16, the linear guide element 22 is also movable in a third direction 56 along the first longitudinal axis 16. Movement of the linear guide element 22 in the third direction 56 creates tension in the elastic member 31 connecting the linear guide element 22 to the body 26 containing the ejector pin 28, as shown in FIG. 6B. FIG. 6B further illustrates that the linear guide element 22 is movable in a fourth direction 58, as indicated by the arrow, opposite the third direction 56 along the first longitudinal axis 16. Relaxation of the tension in the elastic member 31 causes the linear guide element 22 to move in the fourth direction 56.

[0065] 7(A)-7(B) show schematic side views of an embodiment of a laboratory equipment door assembly kit 64 including a door frame 52, a door hinge 10 as shown in FIG. 6, and a door leaf 54. In the illustrated embodiment, the door leaf 54 includes mounting elements 66 in the form of fastening holes into which the hollow body 14 can be inserted and secured. The door frame 52 includes a mounting structure 68 configured to mount the linear guide element 22. In an alternative embodiment, the door frame 52 includes the mounting element 66 configured to mount the hollow body 14 on the door leaf 54, and the door leaf 54 includes the mounting structure 68 configured to mount the linear guide element 22. The illustrated mounting structure 68 includes a stationary plate 70 including a first side 72, a second side 74, an elongated slot 76, and a locking location 78. A top view of the stationary plate 70 is shown in FIG. 7B. The elongated slot 76 is configured to insert a linear guide element 22 into the locking location 78, as shown in FIGS. 8B and 8C. As further shown in FIG. 8C, the hollow body 14 is slidable on the first side 72 of the stationary plate 70 when the linear guide element 22 is inserted into the elongated slot 76. The mounting structure 68 further includes a lead-in slope 80 configured to exert additional force on the linear guide element 22 when the linear guide element 22 is inserted into the elongated slot 76. The linear guide element 22 can move in the third direction 56 when the lead-in slope 80 exerts an additional force on the linear guide element 22, as shown in FIG. 8C. As shown in FIGS. 6B and 8C, the elastic member 31 can build up tension when the linear guide element 22 moves in the third direction 56. The mounting structure 68 further includes a locking recess 82 configured to lock the linear guide element 22, as shown in FIG. 8D. As further shown in FIG. 8D, the elastic member 31 releases its tension when the linear guide element 22 is in the locking position 78. The linear guide element 22 can move in the fourth direction 58 when the elastic member 31 releases its tension.

[0066] The linear guide element (22) is movable into the fixed recess (82) when the linear guide element (22) moves in the fourth direction (58). The support element (48) of the linear guide element (22) is capable of pressing against the second side (74) of the fixed plate (70) when the linear guide element (22) moves in the fourth direction (58).

[0067] Figures 8(A) through 8(D) illustrate a series of steps 86, 88 of a method 84 for assembling a laboratory equipment door assembly kit 64, as shown in Figure 7. In step a) 86 of method 84, a hollow body 14 is placed on a mounting element 66. For example, the hollow body 14 is inserted into a fastening hole, as shown by the arrow in Figure 8(A). Next, in step b) 88 of method 84, a linear guide element 22 is inserted into an elongated slot 76, as shown by the arrow in Figures 8(B) and 8(C), until the linear guide 22 reaches a fastening position 78, as shown in Figure 8(D). As shown in Figure 8(C), a lead-in ramp 80 exerts additional force on the linear guide element 22 as it is inserted into the elongated slot 76. The linear guide element 22 moves in the third direction 56 when the lead-in slope 80 exerts an additional force on the linear guide element 22 and the elastic member 31 builds up tension. In Figure 8(D), the linear guide element 22 is in the fixed position 78 and the elastic member 31 releases its tension. Releasing the tension in the elastic member 31 causes the linear guide element 22 to move in the fourth direction 58 into the fixed recess 82, and the support element 48 of the linear guide element 22 presses against the second side 74 of the fixed plate 70.
