Description

Technical Field

[0001] This invention relates to the field of pivot door anchoring devices for pivotally connecting a pivot hinge member for a pivot door to a structural element. For example, the pivot door anchoring device is configured to receive (e.g., along the lower edge of the door) a pivot pin mounted to the pivot hinge member of the door. Background Technology

[0002] Pivot door anchoring devices are typically installed to structural elements, such as floors, ceilings, or door frames, using protruding anchoring members (e.g., embedded in or otherwise secured to the floor, such as anchor fasteners, like anchor bolts).

[0003] In commonly known embodiments, the pivot door anchoring device receives a pivot pin mounted to the pivot hinge member of the pivot door. Alternatively, the pivot door anchoring device includes a pivot pin received in an opening in the pivot hinge member of the door.

[0004] The pivot door has an upper edge, a lower edge, an inner edge, and an outer edge, and the pivot pin defines the vertical pivot axis for the pivot door.

[0005] In practice and in known embodiments, the pivot pins of the pivot hinge members for a pivot door and the pivot door anchoring devices are configured such that the pivot door has at least one stable position (e.g., a closed position) relative to the structural element, and the pivot door can rotate in two directions about a vertical pivot axis relative to this stable position (e.g., corresponding to the closed position). In other words, the pivot door can thus rotate about a vertical pivot axis and therefore swing in two directions between a closed position and an open position. This vertical pivot axis for the door is typically defined by a pivot pin at its upper end and a pivot pin at its lower end.

[0006] To install a pivot door satisfactorily, some adjustments may be needed to the angular orientation and / or position of the pivot pins, such as to align the two pivot pins and / or to align the pivot door with its surroundings, such as walls, door frames, etc.

[0007] For example, a pivot door anchoring device is known from US2021025208, which discloses an adjusting seat for a door closer. The adjusting seat includes a fixed member configured to be secured to a floor surface and an adjusting member configured to receive a pivot pin of a pivot hinge. The adjusting member is adjustablely arranged on the fixed member. The fixed member is provided with two upwardly projecting square protrusions, each extending into a corresponding wider opening in the adjusting member. For each opening, the adjusting member is provided with a plurality of adjusting fasteners that engage with the protrusions. In the loosened state of all adjusting fasteners, the adjusting member is movable relative to the fixed member in a horizontal plane to set the angular orientation and position of the adjusting member. In the tightened state of the adjusting fasteners, the adjusting member is fixed relative to the fixed member. This known pivot door anchoring device has disadvantages, as the adjusting anchoring device is, for example, cumbersome.

[0008] A pivot door anchoring device is known from CN104653009B, particularly the embodiment disclosed with respect to its figures 6a, 6b, and 6c. In this document, a sliding body is located within a central space of the anchor body. The sliding body can be moved for adjustment in the horizontal axial direction by adjusting two threaded fasteners arranged in axially threaded holes at opposite axial ends of the anchor body. In the horizontal direction perpendicular to the axial direction, each outer wall portion of the anchor body is provided with two vertically threaded holes, each provided with a threaded fastener. These four fasteners engage opposite outer surfaces of the sliding body and form a linear guide structure adapted to guide the sliding body linearly relative to the anchor body in the horizontal axial direction. Additional openings in these outer wall portions of the anchor body provide passage to other threaded fasteners installed in corresponding vertical holes in the sliding body. These other threaded fasteners engage with lever members and allow adjustment and fixation of the angular position of a pivot pin member rotatably arranged in the sliding body about a pivot axis.

[0009] In use, the pivot anchoring device is subjected to significant and repetitive forces and impacts due to the opening and closing of the door and the weight of the door (which is usually very significant).

[0010] Known pivot door anchoring devices are not satisfactory in terms of structural robustness. In this regard, it should be noted that these devices are expected to operate reliably for many years in practice without requiring maintenance. Furthermore, adjusting known pivot door anchoring devices during installation to achieve proper door alignment is cumbersome. Utility Model Content

[0011] The purpose of this invention is to overcome at least partially one or more of these disadvantages, and / or to provide an improved or alternative pivot door anchoring device.

[0012] This utility model provides a pivot door anchoring device for pivotally connecting a pivot hinge component of a pivot door to a structural element, wherein the pivot door anchoring device includes:

[0013] An anchor body is constructed to be installed onto a structural element, such as a floor, to anchor the pivot door anchoring device onto the structural element;

[0014] A sliding body that is movable relative to an anchor body;

[0015] A linear guiding structure, suitable for guiding the sliding body linearly relative to the anchor body in the horizontal axial direction;

[0016] A linear adjustment member engages with the anchor body and the sliding body, such that operating the linear adjustment member causes the sliding body to move linearly relative to the anchor body in the axial direction;

[0017] The pivot pin angle adjustment assembly includes:

[0018] A pivot pin member is rotatably arranged in a sliding body about a pivot axis, wherein the pivot pin member has an opening for a pivot pin of a pivot hinge member of a door, or wherein the pivot pin member has a pivot pin that can be connected to a pivot hinge member of a door.

[0019] A lever member, connected to a pivot pin member and extending in the axial direction;

[0020] The lever adjusting member engages with the lever member and the sliding body, such that operating the lever adjusting member causes the lever member and the pivot pin member to rotate about the pivot axis.

[0021] The pivot door anchoring device according to the invention is characterized in that the linear guide structure includes two parallel elongated protrusions projecting upward on the anchor body and two parallel elongated recesses in the sliding body, the protrusions being confined within the recesses to allow the sliding body to linearly adjust its movement relative to the anchor body in the axial direction and to prevent the sliding body from moving relative to the anchor body in the horizontal direction perpendicular to the axial direction.

[0022] Compared to the known devices described above, the axial linear guidance of the sliding body relative to the anchor body is not formed by threaded fasteners. Instead, the anchor body has parallel elongated protrusions confined within recesses in the sliding body. This confinement prevents movement of the sliding body relative to the anchor body in a horizontal direction perpendicular to the axial adjustment direction. As a result, most of the forces (including torsional forces) and impacts borne by the pivot door anchoring device due to the opening and / or closing of the door are absorbed by these mating elongated protrusions and recesses, rather than by multiple vertically arranged threaded fasteners as in the prior art devices described above.

[0023] In a practical embodiment, the sliding body has an outer outer wall portion and an outer end wall portion forming the outside of the anchoring device. For example, this contrasts with the device disclosed in CN104653009B, in which the sliding body is located within the central space of the anchoring body and is therefore hidden and invisible.

[0024] In this embodiment, the pivot pin member is rotatably arranged in the slide body about a pivot axis in a bearing manner between a first bearing portion and a second bearing portion. The first and second bearing portions are located between two elongated protrusions. The inner surface of each bearing portion and the corresponding inner surface of the two elongated protrusions form a mating sliding surface. Thus, the bearing portions can directly transmit forces and impacts to the elongated protrusions of the anchor body, for example, rather than being supported in the vertical direction via threaded fasteners as in CN104653009B.

[0025] In an embodiment, each elongated protrusion has an inner surface and an outer surface, wherein the outer surface of each elongated protrusion and the inner surface of the outer wall portion of the slide body form a mating sliding surface. As will be understood, this is preferably combined with the arrangement discussed above, such that the elongated protrusion is confined in the vertical horizontal direction between the inner surface of the outer wall portion of the slide body and the outer surface of the bearing portion of the slide body.

[0026] In one embodiment, the outer surface of each elongated protrusion defines two axially spaced sliding surfaces that mate with the inner surface of the outer sidewall portion of the slider. In another embodiment, these sliding surfaces are located at opposite ends of the elongated protrusions.

[0027] In an embodiment, each elongated protrusion includes, for example, a lug at an opposite end of the elongated protrusion and a central rib portion connecting the lug, wherein each lug defines a sliding surface of the protrusion that mates with the inner surface of an outer wall portion of the slider, and wherein the outer surface of the central rib portion is recessed inward relative to the sliding surface defined by the lug. This arrangement provides an efficient and robust transmission of force and impact between the slider and the protrusion. Furthermore, this portion of the device is more practical to manufacture compared to sliding contact along the entire length of the protrusion.

[0028] In a practical embodiment, the pivot door anchoring device includes an anchor member that protrudes from the underside of the anchor body and is configured to be fastened to (e.g., embedded in) a structural element (e.g., floor).

[0029] In one embodiment, each elongated protrusion is provided with axially spaced vertical holes, each vertical hole configured to secure an anchor member to the elongated protrusion. For example, each lug is provided with a vertical hole, such as a threaded hole for securing the anchor member to the elongated protrusion with a threaded fastener. This arrangement allows for optimal transmission of force and impact from the protrusion to structural elements (e.g., to the floor). For example, it allows for a relatively thin base plate portion of the anchor body, thus allowing for a limited overall height of the anchoring device.

[0030] In a practical embodiment, the pivot pin angle adjustment assembly includes two lever members that extend radially outward from the pivot pin member in opposite directions.

[0031] In one embodiment, the outer wall portion of the slider is provided with at least one threaded hole extending perpendicular to the axial direction, wherein the lever adjusting member is a threaded fastener in the vertical hole, which is externally accessible and engages with the lever member. For example, there are two axially spaced threaded holes with threaded fasteners in them, each threaded fastener engaging a corresponding one of the two lever members. This provides easy access to lever adjustment for personnel installing the device and the pivot door.

[0032] In one embodiment, the anchor body is provided with an upwardly projecting portion having a threaded axial bore extending in the axial direction. The linear adjustment member is a threaded fastener within the threaded axial bore, arranged between opposing axial faces of the sliding body, and accessible from the axially outer side of the sliding body, thereby allowing movement of the sliding body relative to the anchor body in opposite axial directions. In a practical embodiment, the upwardly projecting portion is integral with the axial end of an elongated protrusion, for example, abutting a lug of the elongated protrusion. In this design, only a single threaded fastener needs to be operated to induce the desired linear movement of the sliding body relative to the anchor body. This is convenient for personnel installing the device and pivot doors.

[0033] In practical embodiments, the sliding body, the anchor body, and the pivot pin component with levers are made of metal (e.g., steel, such as stainless steel).

[0034] In one embodiment, one of the sliding body and the anchor body is provided with a magnet, which is configured to hold the components together, for example, when they are removed from the packaging.

[0035] Pivot door anchoring devices may be provided with markings and / or multiple markings on the sliding body and / or the anchor body to provide installers with sensory cues, such as visual cues, regarding the relative lateral position of the sliding body relative to the anchor body.

[0036] The pivot door anchoring device may be provided with markings and / or multiple markings on the sliding body and / or pivot pin angle adjustment assembly to provide installers with sensory cues, such as visual cues, regarding the relative angular position of the pivot pin angle adjustment assembly relative to the sliding body.

[0037] The second aspect of this utility model relates to a pivot door anchoring device for pivotally connecting a pivot hinge member of a pivot door to a structural element, wherein the pivot door anchoring device includes:

[0038] An anchor body is constructed to be installed onto a structural element, such as a floor, to anchor the pivot door anchoring device onto the structural element;

[0039] A sliding body that is movable relative to an anchor body;

[0040] A linear adjustment assembly, adapted to move a slider linearly between an inward and an outward position, comprises a linear guide structure and a linear adjustment member.

[0041] The linear adjustment member engages with both the anchor body and the sliding body, such that operating the linear adjustment member causes the sliding body to move relative to the anchor body between inward and outward positions.

[0042] The pivot pin angle adjustment assembly includes a lever member and a lever adjustment member that cooperates with the lever member.

[0043] The pivot pin angle adjusting assembly has a pivot pin receiving member connected to the lever member, the pivot pin receiving member having an opening for the pivot pin member of the pivot hinge member, or the pivot pin angle adjusting assembly has a pivot pin member connected to the lever member.

[0044] The pivot pin member or pivot pin receiving member is rotatably arranged in the slide body about the pivot axis, and the lever adjusting member engages with the lever member and the slide body, such that operating the lever adjusting member causes the lever member to rotate about the pivot axis, which in turn causes the pivot pin member or pivot pin receiving member to rotate about the pivot axis.

[0045] The second aspect of the device may be provided with one or more of the features discussed herein.

[0046] In a second aspect embodiment, the linear guide structure includes a mating recess and a protrusion, one of which is disposed in or on an anchor body, and the other in or on a sliding body, wherein the recess is configured such that the mating protrusion moves linearly within the recess between an inward and an outward position along the length of the recess. In one embodiment, the linear guide structure includes additional mating recesses and protrusions, one of which is disposed in or on an anchor body, and the other in or on a sliding body, wherein the additional recess is oriented parallel to the other recess over a length thereof. In one embodiment, the protrusion is confined within the mating recess in a direction perpendicular to the linear movement between the inward and outward positions, thereby preventing significant movement in that vertical direction.

[0047] In a second aspect embodiment, the pivot pin angle adjustment assembly includes two lever members, each lever member being associated with a corresponding lever adjustment member, for example, the two lever members extending radially outward from the pivot pin member or pivot pin receiving member in opposite directions.

[0048] In an embodiment of the second aspect, the anchor body and the sliding body cooperate to form the housing of the pivot door anchoring device, wherein the linear adjustment member and / or the lever adjustment member or multiple lever adjustment members are operable from the outside of the housing, for example, operable on one or more sides thereof.

[0049] This utility model also relates to a method for adjusting a pivot door anchoring device as described herein, wherein the method includes the following steps:

[0050] Operate the linear adjustment member, preferably only one linear adjustment member, to adjust the axial position of the sliding body relative to the anchor body; and / or

[0051] Operate the lever adjustment component to adjust the angle of the pivot pin component relative to the sliding body. Attached Figure Description

[0064] refer to Figures 1 to 7C A first exemplary embodiment of a pivot door anchoring device 1 for pivotally connecting a pivot hinge member fixed to a pivot door to a structural element (e.g., the floor of a building) will be discussed.

[0065] The device 1 includes:

[0066] Anchor 20 is configured to be installed on a structural element, such as a floor, to anchor the pivot door anchoring device 1 to the structural element;

[0067] The sliding body 10 is movably installed relative to the anchor body 20;

[0068] A linear guiding structure is adapted to guide the sliding body linearly relative to the anchor body 20 in a horizontal axial direction (denoted as X);

[0069] The linear adjustment member 31 engages with the anchor body 20 and the sliding body 10 such that operating the linear adjustment member 31 causes the sliding body to move linearly relative to the anchor body 20 in the axial direction X.

[0070] The device 1 further includes a pivot pin angle adjustment assembly, having:

[0071] A pivot pin member 45 is rotatably arranged in the slide body 10 about a pivot axis P. The pivot pin member has an opening 46 for the pivot pin of the pivot hinge member of the pivot door.

[0072] Two lever members 41 and 42 are connected to pivot pin member 45 and extend away from pivot pin member 45 in opposite directions in the axial direction;

[0073] Two lever adjustment members 43 and 44, each of which engages with a corresponding lever member 41 and 42 and a slider 10, such that operating the lever adjustment members 43 and 44 causes the lever members 41 and 42 and the pivot pin member 45 to rotate about the pivot axis P.

[0074] Two lever members 41 and 42 extend radially outward from the pivot member 45 in opposite directions along the X direction.

[0075] The device 1 can be seen as including a linear adjustment component adapted to position the slider 10 in the axial direction in an inward position (e.g., ...). Figure 4C (as shown) and outward positions (e.g., Figure 4A The linear adjustment component has a linear guide structure and a linear adjustment member 31. (As shown) The linear adjustment component moves linearly between the two sides.

[0076] The linear adjustment member 31 engages with the anchor body 20 and with the sliding body 10, such that operating the linear adjustment member 31 causes the sliding body 10 to move relative to the anchor body 20 between an inward position and an outward position.

[0077] The anchor body 20 has a base plate portion 20a, which is configured to rest against a floor or other structural element. Preferably, the base plate portion 20a has a thickness of a few millimeters to keep the total height of the device 1 limited.

[0078] The linear guide structure includes two parallel elongated protrusions 51, 52 projecting upward on the anchor body 20 (here, upward from the base plate portion 20a) and two parallel elongated recesses 53, 54 in the sliding body 10. The protrusions 51, 52 project downward into the recesses 53, 54 in the sliding body.

[0079] exist Figure 3A As can be seen, the anchor body 20 and the sliding body 10 cooperate to form the outer shell of the pivot door anchoring device 1.

[0080] The protrusions 51 and 52 are confined within the recesses 53 and 54 to allow the sliding body 10 to move linearly relative to the anchor body 20 only in the axial direction X, and to prevent the sliding body 10 from moving relative to the anchor body 20 in the horizontal direction perpendicular to the axial direction X.

[0081] The slider 10 has outer wall portions 10a and 10b that form the opposite outer sides of the slider and these sides extend generally in the X direction.

[0082] The linear adjustment member 31 and the lever adjustment members 43 and 44 can be operated from the outside of the slider 10 (here, its axial end and longitudinal side).

[0083] As shown, an outer wall portion 10b is provided with two threaded holes 13, 14 extending perpendicular to the axial direction X. In each hole 13, 14, a corresponding lever adjusting member 43, 44 (implemented here as a threaded fastener) is installed.

[0084] Each fastener 43, 44 is accessible from the outside of the device 1 and engages with the corresponding one of the two lever members.

[0085] As shown, the pivot pin member 45 is rotatably arranged in the slide body 10 in a bearing manner around the pivot axis P between the first bearing portion 71 and the second bearing portion 72. The first bearing portion 71 and the second bearing portion 72 are located between two elongated protrusions 51 and 52.

[0086] Preferably, the inner surfaces of each of the bearing portions 71, 72 and the corresponding inner surfaces of the two elongated protrusions 51, 52 form a mating sliding surface in the axial direction X.

[0087] The pivot pin receiving member 45 and bearing portions 71, 72 are arranged between mating recesses and protrusions 51, 53 and 52, 54. This allows for a compact design of the pivot door anchoring device 1.

[0088] Pivot pin receiving member 45 around pivot axis P (e.g., in Figure 3A(As shown in the diagram) It is rotatably arranged in the slider 10. Lever adjusting members 43, 44 engage with lever members 41, 42 and with the slider 10, such that operating the lever adjusting members 43, 44 causes the lever members 41, 42 to rotate about the pivot axis P, which in turn causes the pivot pin receiving member 45 to rotate about the pivot axis P. For example, in Figure 5B and Figure 5C The diagram shows this rotation caused by operating levers to adjust components 43 and 44.

[0089] exist Figures 5A to 5C The diagram shows a top view of a cross-section of the pivot door anchoring device 1, in which the pivot pin angle adjusting assembly is in a neutral state, a first rotation state, and a second rotation state. In the first rotation state, the pivot pin receiving member 45 is relative to... Figure 5A The rotation angle α of the neutral line NN represents the neutral state. In the second rotation state, the pivot pin receiving member 45 rotates relative to the neutral line NN by an angle β.

[0090] The operating lever adjustment components 43 and 44 allow adjustment of the angle of the pivot pin component 45 relative to the sliding body 10.

[0091] Each elongated protrusion 51, 52 has an inner surface 51a, 52a (facing another protrusion) and an outer surface 51b, 52b. The outer surface 51b, 52b of each elongated protrusion 51, 52 forms a mating sliding surface with the adjacent inner surface 11a, 11b of the outer wall portion 10a, 10b of the slider.

[0092] Anchor member 21 protrudes from the underside of anchor body 20 and is configured to be fastened to (e.g., embedded in) structural elements (e.g., floor).

[0093] Each elongated protrusion 51, 52 is provided with axially spaced vertical holes 90, each hole 90 being configured to secure the anchor member 21 to the elongated protrusion.

[0094] For example, as shown, each hole 90 in the protrusions 51, 52 is a threaded hole for securing the anchor member 21 to a threaded fastener (e.g., a screw or bolt) of the elongated protrusions 51, 52.

[0095] More specifically, each of the elongated protrusions 51, 52 includes lugs 62, 64 at opposite ends of the elongated protrusion and intermediate rib portions 61, 63 connecting these lugs. Holes 90 are provided in the lugs 62, 64.

[0096] The anchor body 20 is provided with an upwardly projecting portion 20b, which is provided with a threaded axial hole 32 extending in the axial direction X. The linear adjustment member is a threaded fastener 31 in the threaded axial hole 32.

[0097] A threaded fastener 31 is arranged to engage between opposing axial faces 12a and 12b of the slide body 10. The head end engages on face 12a, and the shaft end 31c engages on face 12b. A tool can access the head end of the fastener 31 from the axially outer side 10c of the slide body via the axial hole 12 to rotate the fastener. This allows the slide body 10 to be moved relative to the anchor body 20 in the opposite axial direction by rotating one fastener 31. Moving the slide body 10 inward is achieved by turning the fastener 31 so that the thread 31b disengages from the thread 32 of the anchor body 20. Tightening the fastener 31 in the opposite direction presses the end face 31c against the slide body 10, causing it to move outward.

[0098] exist Figures 4A to 4C The diagram shows a top view of the cross-section of the pivot door anchoring device 1, with the linear adjustment components in the outward, neutral, and inward positions, respectively.

[0099] exist Figure 4C In the inward position shown, one end of the protrusion 51 is adjacent to the inward edge 53a of the recess 53. Figure 4A In the outward position shown, the other end of the protrusion 51 is adjacent to the outward edge 53b of the recess 53.

[0100] exist Figures 6A to 6C As can be seen, the pivot door anchoring device 1 is provided with markings 81, 82 on the sliding body to provide sensory cues, such as visual cues, to personnel installing the device 1 and / or the door regarding the relative lateral position of the sliding body 10 relative to the anchor body 20.

[0101] exist Figure 6B In the neutral state shown, the markings 81 and 82 on the sliding body 10 are located on both sides of the anchor body 20. Therefore, these markings are, for example, visible and / or tangible to the installer.

[0102] exist Figure 6A In the outward-facing state shown, only mark 81 is located on one side of the anchor body 20, and because the sliding body 10 has moved laterally, it is located above mark 82.

[0103] exist Figure 6A The inward-facing state shown in the figure has only mark 82 located on one side of the anchor body 20, as the sliding body 10 has moved laterally, causing it to be located above mark 81.

[0104] exist Figures 7A to 7C As can be seen, the pivot door anchoring device 1 is provided with markings 83 and 84 on the sliding body 10 and the pivot pin angle adjustment assembly to provide sensory cues (e.g., visual cues) to personnel installing the device 1 and / or the door regarding the relative angular position of the pivot pin angle adjustment assembly relative to the sliding body 10.

[0105] exist Figure 7B In the neutral state, markers 83 and 84 are aligned. In the first rotation state ( Figure 7A ) and second rotation state ( Figure 7C In the image, marks 83 and 84 are misaligned, and mark 84 is rotated to the right and left of mark 83, respectively.

[0106] like Figure 8 As schematically shown, the pivot door hinge system includes a pivot door anchoring device 1 and a pivot hinge member 210 fixed to the pivot door 250.

[0107] The door 250 has an upper edge, a lower edge 251, an inner edge 252 (e.g., a wall facing the building), and an outer edge. Here, a pivot hinge member is mounted to the lower edge 252 of the pivot door. The pivot door anchoring device 1 is mounted to a structural element (here, floor 260).

[0108] The pivot hinge member 210 includes a downwardly projecting pivot pin 211, which is received in an opening 46 of the pivot pin member 45 of the pivot door anchoring device 1. The pivot pin 211 is non-rotatably fixed in the pivot pin member because their mating cross-section is non-circular (here, elliptical). Other fixing arrangements (e.g., using cross-sections, such as spline connections) are also possible.

[0109] The pivot hinge component 210 includes a housing, which is mounted to the pivot door 250.

[0110] In this example, the pivot hinge member 210 further includes a spring mechanism 213 adapted to drive the cam follower 212 against the cam 211a of the pivot pin 211, thereby defining one or more stable positions of the door 250 and / or providing bias of the door toward one or more stable positions (e.g., toward the closed position).

[0111] The linear adjustment member 31 of the pivot door anchoring device 1 allows adjustment of the lateral position of the sliding body 10 relative to the anchor body 20, thereby adjusting the lateral position of the pivot pin member 211 relative to the anchor body 20, and thus adjusting the position of the pivot pin member 211 relative to the floor 260.

[0112] The lever adjustment members 43 and 44 of the pivot door anchoring device 1 allow adjustment of the angle of the pivot pin member 211 relative to the sliding body 10, thereby adjusting the angle of the pivot pin member 211 relative to the sliding body 10.

[0113] In use, when installing device 1 and door 250, device 1 can be adjusted using the following method, which includes the following steps:

[0114] Operate a linear adjustment member 31 to adjust the axial position of the sliding body 10 relative to the anchor body 20, and / or

[0115] Operate the two lever adjustment components 43 and 44 to adjust the angle of the pivot pin component 45 relative to the slider 10.
