KIT FOR ADJUSTING THE HEIGHT OF A DOOR WITH RESPECT TO THE FLOOR

Description

Field of invention

[0001] The present invention is generally applicable to the technical field of the accessories for doors, in particular for reinforced doors, and relates to a kit that includes a device for adjusting the height of a door, in particular a reinforced door, with respect to the floor, as well as to a system that includes such a kit.

[0002] The invention further relates to a method for adjusting the height of a door, in particular a reinforced door, with respect to the floor.

Background of the invention

[0003] It is known that the mounting of a door, in particular a reinforced door, is accomplished by first mounting the movable leaf of the hinges on the door and the fixed body on the support frame thereof and subsequently connecting the door to the frame by means of mutual coupling of movable leaf to the fixed bodies, generally by sliding the former with respect to the latter.

[0004] Subsequently, as shown in Figures 1a and 1b, it is carried out the adjustment of the height h of the door D with respect to the floor FL by means of a suitable lifting device L interposed between the floor FL and the door D.

[0005] By acting on the lifting device L, the operator applies a lifting force F1, which is imparted to all the components rigidly connected to the door D, and in particular to movable leafs MM of the hinges H.

[0006] Therefore, the force F1 besides to raise the door D from the floor FL tends to lift the movable leafs MM of the hinges H with respect to the fixed bodies FM, which are rigidly connected to the frame F. Subsequently, the manual repositioning of the fixed bodies FM at the desired height occurs.

[0007] One of the apparent drawbacks of the use of the lifting devices L is the fact that they do not ensure the maintenance of the original height with time.

[0008] In fact, the manual repositioning of the fixed bodies FM of the hinges H does not ensure that the weight of the door D is homogeneously distributed on both hinges H. This causes besides to the gradual lowering of the door D possible misalignments and/or malfunctioning thereof. Therefore, a frequent maintenance of the door D is needed, which is an economic burden.

[0009] Moreover, the high weight of the door requires the use of several operators for such an height adjustment. In fact, while one or more operators lift the door, another operator adjusts the hinges to the desired height.

[0010] Another well-known drawback of such lifting devices L is that they wear the floor on which the device rests. This drawback is particularly felt with delicate floorings, for example made of tiles or wooden floors.

[0011] Further, these known lifting devices L are rather expensive and complicated to use, so that any height adjustment of the door must be done by expert operators.

[0012] Moreover, in case of slippery floor or wrong position between the floor and the door, these lifting devices L are rather dangerous for the operators.

[0013] Last but not least, the frame F may deform with use, with consequent misalignment of the door or the need for maintenance or replacement of the same frame F.

[0014] The European patent application EP1215357 discloses a concealed hinge with a fixed element that includes a longitudinal guide hole for a pivot that rotates unitary with the movable element of the same hinge. The fixed element includes a screw adapted to act on the pivot to adjust its position with respect to the fixed element.

[0015] This known hinge does not solve the above mentioned drawbacks.

[0016] In particular, this hinge does not ensure that the weight of the door is homogeneously distributed between the hinges, with the consequent need for frequent maintenance of the door.

Summary of the invention

[0017] Object of the present invention is to overcome at least partly the above mentioned drawbacks, by providing a device for adjusting the height of a door, in particular a reinforced door, of high functionality, constructional simplicity and/or low cost.

[0018] A particular object of the invention is to provide a kit comprising two hinges and a device for adjusting the height of a door, in particular a reinforced door, which allows to maintain the position of the door during time.

[0019] Another object of the invention is to provide a kit comprising a device which allows the adjustment of the height of a door, in particular a reinforced door, by a single operator.

[0020] Another object of the invention is to provide a kit comprising a device for adjusting the height of a door, in particular a reinforced door, which allows to preserve the floor below the door.

[0021] Another object of the invention is to provide a device which allows immediate and simple adjustment of the height of a door, in particular a reinforced door, even by unskilled operators.

[0022] Another object of the invention is to provide a kit comprising a device for adjusting the height of a door, in particular a reinforced door, which is safe for the operators involved in the mounting thereof.

[0023] These objects, as well as others that will appear more clearly hereinafter, are achieved by a kit comprising a device for adjusting the height of a door, in particular a reinforced door, with respect to the floor having one or more of the features herein described and/or claimed and/or shown.

Detailed description of a preferred embodiment

[0029] With reference to figures 2a to 10b, the system 1 is particularly useful for adjusting the height h of a door D with respect to the floor FL.

[0030] In particular, the door D may be a reinforced door, and can be fixed to a support structure formed by a tubular frame F and a counterframe CF, mutually coupled to each other.

[0031] However, the system 1 may be useful to adjust the height h of any door D, connected to any type of tubular support structure, without departing from the scope of the appended claims.

[0032] Essentially, in addition to the tubular support structure, the system 1 includes two or more hinges 100, 200 connected to the door D for rotatably moving thereof about a rotation axis Y' and at least one actuator device 300, whose function will be explained later.

[0033] The at least one actuator device 300 is spaced apart from the hinges 100, 200, and does not belong thereto.

[0034] Preferably, a single actuator device 300 may be provided.

[0035] The hinges 100, 200 are slidably mounted on the tubular support structure for sliding along an axis Y substantially parallel to the rotation axis Y' of the door D, and can be removably fastened on the tubular support structure F, CF.

[0036] To do this, the hinges 100, 200 may be mounted by means of suitable screws 101, 201 which pass through elongated slots A, A' passing through the frame F, which elongated slots A, A' may define the sliding axis Y.

[0037] Therefore, when the screws 101, 201 are unfastened the hinges 100, 200 are free to slide along the axis Y for a stroke defined by the elongated slots A, A'. Conversely, by fastening the screws 101, 201 it is possible to block the sliding of the hinges 100, 200 with respect to the tubular support structure F, CF.

[0038] In particular, as shown in the attached figures, the hinges 100, 200 are of the concealed type. Each hinge 100, 200 may include a respective fixed element 110, 210 mounted within the tubular support structure F, CF and a respective movable element 120, 220 pivoted on the respective fixed element 110, 210 to rotate about the rotation axis Y' between an open door D position and a closed door D position.

[0039] Further, each movable element 120, 220 includes a fixing leaf 130, 230 for fixing to the door D susceptible to concealedly retract within the tubular support structure F, CF in the closed door D position and to visibly extend from the same tubular support structure F, CF in the open door D position.

[0040] Advantageously, the hinges 100, 200 may be made of two parts cooperating with each other.

[0041] FIGs. 11, 12 and 13 for sake of simplicity show only the structure of the hinge 100. It is understood that in a preferred but not exclusive embodiment of the invention the hinge 200 also may have the same structure.

[0042] In particular, the fixed element 110 of the hinge 100 may be defined by a lower half-hinge with a first box-shaped hinge body 112, while the movable element 120 thereof may be defined by an upper half-hinge with a pivot 121 defining the rotation axis Y' of the door D.

[0043] The box-shaped hinge body 112 may include a passing-through hole 114 within which the pivot 121 can be inserted to rotatably support it.

[0044] Advantageously, means 115 may be provided for blocking the axial sliding of the pivot 121 with respect to the box-shaped hinge body 112, so as to prevent the slipping and/or the misalignment thereof upon the sliding of the hinges 100, 200 along the first axis Y.

[0045] Suitably, as particularly shown in FIG. 12, such means 115 for blocking the axial sliding may include an axial blind hole 116 made at the lower end 121' of the pivot 121 adapted to receive a blocking screw 117, with the possible interposition of a pressing element 118, for example a washer.

[0046] In the event of forces that promote the lifting of the pivot 121, the impact of the blocking screw 117 and possibly of the pressing element 118 against the box-shaped hinge body 112 prevents the slipping of the pivot 121 from the same passing-through hole 114 and/or the misalignment of the same pivot 121.

[0047] To facilitate the rotation of the pivot 121, one pair of antifriction elements 119, 119' may be provided, for example bearings, preferably of the axial-radial type, at both ends of the same pivot 121.

[0048] In a preferred but not exclusive embodiment, as particularly shown in FIG. 13, the fixing leaf 130 of the upper half-hinge defining the mobile element 120 of the hinge 100 may include an anchoring plate 131 for anchoring to the door D.

[0049] This anchoring plate 131 greatly simplifies the mounting of the door D on the hinges 100, 200. In fact, as shown in FIG. 13, the anchoring plate 131 is removably coupled to the fixing leaf 130 by means of fastening screws 132, which may be lockable in suitable locking elements 133.

[0050] Therefore, to mount the door D it is necessary to fix the hinge 100 to the tubular support structure F, CF without the anchoring plate 131 (or remove it once the hinge is fixed), to anchor the latter to the door D and then coupling the door D to the tubular support structure F, CF by coupling the anchoring plate 131 anchored to the door D with the fixing leaf 130 of the hinge 100 anchored to the tubular support structure F, CF. Once those parts are coupled, it is possible to avoid the mutual decoupling by means of the screws 132 and the locking elements 133, the latter being in turn engaged in the slots 134.

[0051] Moreover, by moving the screws 132, and the locking elements 133 along the directions defined by the slot 134 and suitably acting on the screws 132 it is possible to adjust the position of the door D with respect to the tubular support structure F, CF.

[0052] In case the hinge 200 has the same structure of the hinge 100, to mount the door D it is necessary acting as above also for the hinge 200.

[0053] The actuator device 300 is configured to act on the operative portion 111 of one of the hinges 100, 200, preferably the lower hinge 100, to move it along the axis Y.

[0054] Preferably, the operative portion 111 may be defined by the lower surface of the fixed element 110 of the bottom hinge 100.

[0055] To this end, the actuator device 300 comprises a main body 310 and a slider 320 which can slidably move along the axis Y.

[0056] However, It is understood that the slider 320 can slide along an axis substantially parallel to the axis Y without departing from the scope of protection of the appended claims.

[0057] The main body 310 may be fixable within the tubular support structure F, CF by means of the screws 311.

[0058] On the other hand, the main body 310 may be fixed within the tubular support structure F, CF, for example may be monolithic therewith, without departing from the scope of protection of the appended claims.

[0059] The slider 320 can slide in a seat 312 of the main body 310. Accordingly, the seat 312 may be open at the top side.

[0060] Moreover, the seat 312 may slidably guide the slider 320. To do this, the latter may have a shaped side wall 321, while the seat 312 may have a corresponding countershaped side wall 313 which interacts with the shaped side wall 321 of the slider 320 so as to guide the sliding of the latter along the axis Y.

[0061] For example, the seat 312 of the main body 310 of the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 2a to 8 may have substantially parallelepiped shape, as well as the slider 320. In this embodiment, the flat and substantially parallel faced side walls of the seat 312 interacts with the corresponding flat and substantially parallel faced side walls of the slider 320 to guide the sliding thereof along the axis Y.

[0062] On the other hand, in the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 9 to 10b, the seat 312 of the main body 310 may have a substantially cylindrical shape, as well as the slider 320. In this embodiment, the substantially cylindrical side wall of the seat 312 interacts with the corresponding substantially cylindrical side wall of the slider 320 to guide the sliding thereof along the axis Y.

[0063] In any case, the slider 320 may include a first lower portion 322 facing a corresponding second lower portion of the seat 312, which may be defined by the bottom wall 314, and an upper portion, which may be defined by the upper flat wall 323, facing the operative portion of the hinge 100, which may be defined by the bottom wall 111 of the fixed element 110, to interact or preferably abuts therewith.

[0064] In order to move the slider 320 along the axis Y, the main body 310 may include an adjustment screw 330 interacting therewith. In particular, the adjustment screw 330 may be accessible from outside the tubular support structure F, CF by a user, which may act thereon by acting on the control portion 331 of the adjustment screw 330.

[0065] Suitably, the adjustment screw 330 may be slidable along an axis X substantially perpendicular to the axis Y. Therefore, the action on the control portion 331 promotes the sliding of the adjustment screw 330 along the axis X.

[0066] To move the slider 320 along the axis Y, the adjustment screw 330 may include a substantially wedge-shaped operative portion 332 susceptible to come into contact with a first substantially countershaped operative zone 324 of the same slider 320.

[0067] In this way, the sliding of the adjustment screw 330 along the axis X corresponds to the sliding of the slider 320 along the axis Y and in turn to the variation of the mutual distance d between the second lower portion 314 of the seat 312 and the first operative zone 324 of the slider 320.

[0068] At the same time, the position along the axis Y of the upper portion 323 of the slider 320 varies, as well as the position along the axis Y of the hinges 100, 200. In fact, the upper portion 323 of the slider 320 is in abutment and in contact with the bottom wall 111 of the fixed element 110 of the hinge 100, and therefore the sliding of the former along the axis Y corresponds to the sliding of the latter. Since the other hinge 200 is rigidly connected to the first hinge 100 by means of the door D, the sliding of the latter hinge 100 along the axis Y (which is promoted by the sliding of the slider 320, in turn caused by the user through the adjustment screw 330) corresponds to the sliding of the first hinge 200.

[0069] Therefore the user, by simply acting on the adjustment screw 300, may vary in a simple, fast and secure way the height h of the door D from the floor FL.

[0070] An apparent advantage of the system 1 is that the actuator device 300 does not act directly on the door D as the lifting devices L of the state of the art, for example shown in FIGs. 1a and 1b, but acts on the hinges 100, 200.

[0071] This allows to distribute in a perfectly homogeneous way the weight of the door D on the same hinges 100, 200, which is a great advantage in terms of maintaining their original position during time. This allows, in addition, to minimize maintenance on the door D, and therefore to minimize costs.

[0072] Thanks to the above mentioned features, the slider 320 may be slidable along the axis Y between a first operative position, shown for example in FIGs. 4b and 10a, in which the operative zone 324 thereof is proximal to the bottom wall 314 of the seat 312 and a second operative position, shown for example in FIGs. 5b and 10b, in which the first operative zone 324 of the slider 320 is distal from the bottom wall 314.

[0073] From the figures it is apparent that the height h of the door D with respect to the floor FL is relatively higher when the slider 320 is in the second operative position.

[0074] In the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 9 to 10b, the first operative zone 324 may coincide with the first lower portion 322. On the other hand, in the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 2a to 8 the first operative zone 324 may be defined by a recess interposed between two end projections 325', 325".

[0075] In order to determine the stroke of the slider 320, the latter may comprise at least one second operative zone cooperating with a corresponding at least one operative area of the main body 310 to define the blocking means of the stroke of the same slider 320.

[0076] In particular, in the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 9 to 10b, the slider 320 includes a single second operative zone 326, while the main body 310 may include a single operative zone 315 cooperating therewith. On the other hand, in the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 2a to 8 the slider 320 includes a pair of second operative end zones 326', 326", while the main body 310 may include a corresponding pair of operative zones 315', 315" cooperating therewith.

[0077] Suitably, in a preferred but not exclusive embodiment, the blocking means may include at least one passing-through slot made on one of the slider 320 and the main body 310 and at least one blocking pin inserted into a seat formed on the other of the slider 320 and the main body 310.

[0078] More particularly, in the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 9 to 10b, the blocking means include a single passing-through slot 340 made on the operative zone 315 of the main body 310 and a corresponding single blocking pin 341 inserted through a single seat 342 made on the operative zone 326 of the slider 320.

[0079] On the other hand, in the preferred but not exclusive embodiment of the actuator device 300 shown in FIGs. 2a to 8 the blocking means include a pair of passing-through slots 340', 340" made on the operative end zones 326', 326" of the slider 320 and a corresponding pair of blocking pins 341', 341" inserted through seats 342', 342" made on the operative zones 315', 315" of the main body 310.

[0080] In any case, the slots 340, 340', 340" and the blocking pins 341, 341', 341" are mutually engaged and mutually interacting so as to define the positions of maximum and minimum height h of the door D from the floor FL, shown for example in Figures 5c, 10b and 4c, 10a.

[0081] By suitably dimensioning and/or configuring the system 1, and in particular the tubular frame F, CF, the hinges 100, 200 and the actuator device 300, it is possible to obtain that when the slider is in the first operative position, as shown for example in Figures 4b and 10a, the door D is in contact with the floor FL, so as to rest on it.

[0082] This greatly simplify the installation and adjustment of the door D, that may also be carried by a single operator- This makes these operations extremely safe.

[0083] Furthermore, in the case of hinges 100, 200 that allow other adjustments of the position of the door in addition to the vertical one, the above feature allows these adjustments in a simple and safe way.

[0084] In this case, the hinges 100, 200 include means for adjusting the horizontal position and the opening angle of the door.

[0085] It is clear that the support to the floor of the door during mounting allows to do all the above adjustments in a simple and safe manner, by further preserving the integrity of both the hinges of the door.

[0086] In a preferred but not exclusive embodiment, shown for example in Figures 7 and 8, the system 1 may include a support element 350 interposed between the actuator device 300 and the floor FL, so that the load of the door D is completely loaded on the floor FL.

[0087] This preserves over time the integrity of both the hinges 100, 200 and the support structure F, CF. This as well greatly ensures the maintenance of the original position of the door D over time.

[0088] The support element 350 may have an upper surface 351 susceptible to come in contact against an abutment surface 316 of the main body 310 of the actuator device 300 and a lower opposite surface 352 susceptible to rest on the floor FL, within the tubular support structure F, CF.

[0089] From the above description, it is apparent that the system 1 fulfils the intended objects.

[0090] In fact, the system 1 highly functional, simple to manufacture and/or low cost.

[0091] Thanks to the particular configuration and/or positioning on the tubular support structure F, CF, the adjusting of the height h of the door D from the floor FL may even be made by a single operator.

[0092] Thanks to the high simplicity and functionality, the system 1 can be used even by unskilled personnel.

[0093] Moreover, thanks to the fact that the system 1 fully loads on the floor the weight of the door D, the latter maintains unchanged over time the original position.

[0094] It is further clear that in the system 1 any component, and in particular the actuator device 300, rests on the floor FL. This allows to preserve the latter from scratches and, in general, from wearing.

[0095] Furthermore, in this way the adjusting of the height h of the door D is extremely safe.

[0096] The system 1 further avoids misalignment and/or malfunction of the door D due to an inhomogeneous distribution of the weight thereof on the hinges, which is a usual drawback of the systems of the state of the art.

[0097] While the invention has been described with particular reference to the accompanying figures, the numerals referred to in the disclosure and claims are only used for the sake of a better intelligibility of the invention and shall not be intended to limit the scope of the appended claims in any manner.
