Definitions
- the present invention relates to the field of doors and windows, in particular of the metallic type. More precisely, the invention relates to a rotational support for an opening handle for doors, windows and the like.
- opening and closing handles and relative support mechanisms and connection to doors and to the corresponding command mechanisms of the fastenings have a fundamental importance.
- rotation which in general do not exceed 30°, the clearing of the lock and the opening of the door which turns about a support hinge is obtained.
- handles are connected directly to the lock by means of prismatic pivots supporting the entire load that the user transmits to the door, the handles being fixed to said pivots by means of blocking pins.
- Other types of handles turn in supports secured to the doors in correspondence with the lock, and the prismatic pivot has only the burden of transmitting the rotation of the handle to the lock itself, while the support holds all the other loads.
- its non-free end is riveted during assembly to the support itself or, alternatively, the non-free end of the handle is threaded in order to screw a locking nut on to it.
- the handle In the case of the head riveted in the assembly step, it is not possible in a successive step to dismount the handle from the support, for example for possible future surface treatments and coloration of the handle. In the case, on the other hand, of the threaded head and locking nut, the handle requires greater processing and therefore is more expensive.
- Handles of this type and the relative supports now known also do not allow for the inversion between right-hand and left-hand mounting of said handle requiring the assembly of handles with either "right” or “left” type supports to be applied correspondingly to the two opposite faces of the door.
- One of the objects of the present invention is to provide a support for handles of doors, windows and the like wherein the handle is of both easy construction and easy dismountability from the support itself, i.e. for surface treatment and coloration after assembly or successive inversions between left and right-hand mounting.
- a second object of the present invention is to provide an easily anchorable support for handles of doors, windows and the like, in particular those made of metallic sections, and adaptable to each of the above-described interaxes.
- a further object of the present invention is to provide a fixing insert for handle supports which is quick and simple to mount.
- the handle support which comprises a rotational housing for the neck of the handle, means for the elastic recovery of the handle to a resting position and means of anchorage to the door.
- the support is characterized in that a first and a second half-bushing in antifriction material are engaged reciprocally to form the rotational housing and are engaged in two cavities formed in the two opposite faces of a rigid support plate.
- the support plate and each of the two above-mentioned half-bushings each have a central elongated hole for the introduction, during the mounting step, of a head projecting from the neck of the handle.
- the means of elastic recovery of the handle comprises a first sliding block counteracted by a spring against which the head formed on the neck of the handle is engaged; a second block acts as a limit stop in the return movement of the handle. Both blocks are connected slidingly to the second half-bushing and are therefore dismountable and interchangeable so that the mounting of the handle in either a right-hand or left-hand position according to the side of the door to be mounted is easily allowed for.
- the anchorage of the support to the door is facilitated by threaded inserts which are introduced into holes made on the door and tightened by means of screws which cause the insert to expand inside the hole thus creating a permanent, non dismountable anchorage.
- anchorages with different interaxes are possible.
- a support according to the invention for an opening handle 1 of a door, window and the like comprises a rigid plate 2 with cavities 2a and 2b wherein a first half-bushing 3 and a second half-bushing 4 are engaged. More precisely the half-bushing 3 presents projections 5a and 5b suitable for being engaged in cavity 2a formed in the plate 2 in order to prevent tangential displacements with respect to the plate whereas the half-bushing 4 is shaped to enter cavity 2b with precision.
- the half-bushings 3 and 4 have a substantially flat form with projections 5 and 6 in the form of portions of cylindrical shell respectively able to be reciprocally engaged after mounting on the plate 2 to form a cylindrical seat of rotation for a neck 8 extending from the end 1a of the handle 1.
- the half-bushings 3 and 4 are advantageously made of anti-friction material and present slot holes, respectively 9 and 10, for allowing the introduction of a head 11 which projects from the neck 8 of the handle 1 and presents two projections 11a and 11b extending in a direction orthogonal to the rotational axis of the neck 8.
- a slot hole 12 is provided for the introduction of the head 11 and has a circular central part for the introduction of the semicylindrical shell portions 5 and 6 of the half-bushings 3 and 4.
- the slot holes 9, 10 and 12 of the half-bushings 3, 4 and of the plate 2 respectively, have a form which allows the introduction of the head 11 of the handle 1 but does not allow disengaging after the handle 1 has effected a relative rotation of 90° with respect to them, whereby the projections 11a and 11b abut against the edges of the circular central part of the above-mentioned holes.
- the support according to the invention also comprises a first block 13 with which a spring 14 is engaged and is provided with a protrusion 15 having a T-shaped transversal section able to engage with a corresponding guide 16 made in the half-bushing 4.
- Another guide 16 is created on the opposite side of the half-bushing 4 and is able to engage with a protrusion 17 also having a T-shaped transversal section made in a block 18.
- the support according to the invention also comprises a protective cover 19 having a hole 20 for its introduction onto the handle 1 and of the same form as the first half-bushing 3, as well as teeth 21 shown on the internal sides of the cover 19 itself for engaging with corresponding notches 22 made on the corresponding external faces of the plate 2.
- means of anchorage are provided for comprising threaded inserts 23 having squared heads 24 and shanks 25 with internally threaded ends 25a and a central part 25b having thin walls.
- the square heads 24 of the inserts 23 are able to engage with a rectangular groove 26 made on the face 2a of the plate 2.
- On the groove 26 a couple of through holes 27 is also made, each couple formed by two intersecting parallel holes and having a flared opening, as can be seen in figures 1 and 3.
- the mounting of the handle 1 in the support according to the invention is effected as follows: the head 11 of the handle 1 is introduced into the hole 9 of the first half-bushing 3 and is turned by 90° with respect to it.
- the half-bushing 4, to which blocks 13 and 18 have been previously connected by engaging the T-shaped protrusions 15 and 17 respectively in the guides 16, is then introduced into the cavity 2b of the plate 2 together with the spring 14 which engages in block 13.
- the head 11 of handle 1 is introduced into slot hole 12 of the plate 2 and into slot hole 10 of the second half-bushing 4.
- a second rotation of 90° is imposed to the handle 1 in order to prevent the disengagement of the head 11 from the holes 10 and 12 in that the projections 11a and 11b abut against the edges of the circular portions of the holes 10 and 12 themselves.
- the projection 11a of the head 11 of the handle 1 is inserted between the second block 18 and the first block 13, causing a displacement of the block 13 in the direction of compression of spring 14 so that the projection 11a, during the above-mentioned 90° rotation, comes in contact with it, as shown with a dashed line in figure 3, and arranges itself definitively in the position indicated with a continuous line in the same figure.

The support comprises a plate (2) wherein there are housed two half-bushings (3, 4) creating the seat of rotation of the neck (8) and the handle (1). A fixed block (18) and a mobile block (13) contrasted by a spring (14), interchangeable with one another, are also provided for allowing the elastic recovery of the handle (1) after release and the correct horizontal positioning in resting conditions.
Description
- The present invention relates to the field of doors and windows, in particular of the metallic type. More precisely, the invention relates to a rotational support for an opening handle for doors, windows and the like.
- In the field of doors and windows, in particular metallic ones, opening and closing handles and relative support mechanisms and connection to doors and to the corresponding command mechanisms of the fastenings have a fundamental importance. In the most commonly known handles, with a downward rotation of one of their ends beginning from a horizontal position, rotation which in general do not exceed 30°, the clearing of the lock and the opening of the door which turns about a support hinge is obtained.
- Some types of these handles are connected directly to the lock by means of prismatic pivots supporting the entire load that the user transmits to the door, the handles being fixed to said pivots by means of blocking pins. Other types of handles turn in supports secured to the doors in correspondence with the lock, and the prismatic pivot has only the burden of transmitting the rotation of the handle to the lock itself, while the support holds all the other loads. In order to prevent the handle from winding off the support, its non-free end is riveted during assembly to the support itself or, alternatively, the non-free end of the handle is threaded in order to screw a locking nut on to it. In the case of the head riveted in the assembly step, it is not possible in a successive step to dismount the handle from the support, for example for possible future surface treatments and coloration of the handle. In the case, on the other hand, of the threaded head and locking nut, the handle requires greater processing and therefore is more expensive.
- Handles of this type and the relative supports now known also do not allow for the inversion between right-hand and left-hand mounting of said handle requiring the assembly of handles with either "right" or "left" type supports to be applied correspondingly to the two opposite faces of the door.
- As regards the system of anchorage of the handle supports to the doors, in particular when the doors are built by means of metallic sections, in which, as known, holes can be made but are not threadable, currently threaded inserts are used which are introduced into said holes and made integral to the doors themselves by means of a fastening system similar to that which is accomplished with rivets. The support of the handle is then anchored to the door by means of screws which are fastened in the previously mounted inserts. In this case, the anchorage comprise two distinct steps: introduction and locking of the threaded inserts in the door and anchorage of the supports of the handles to the door with a consequent significant expense of time.
- As is known, the interaxes of the holes for anchorage of the handle supports to the doors on which they must operate are unified in order to standardize the market. In particular the two drilling systems most diffused in Europe provide for interaxes of 43 and 50 mm respectively. For each of these interaxes it is therefore necessary to execute a different drilling in the supports of the handles and put on the market supports with holes having both interaxes.
- One of the objects of the present invention is to provide a support for handles of doors, windows and the like wherein the handle is of both easy construction and easy dismountability from the support itself, i.e. for surface treatment and coloration after assembly or successive inversions between left and right-hand mounting.
- A second object of the present invention is to provide an easily anchorable support for handles of doors, windows and the like, in particular those made of metallic sections, and adaptable to each of the above-described interaxes.
- A further object of the present invention is to provide a fixing insert for handle supports which is quick and simple to mount.
- These and other objects are accomplished by the handle support according to the invention which comprises a rotational housing for the neck of the handle, means for the elastic recovery of the handle to a resting position and means of anchorage to the door. The support is characterized in that a first and a second half-bushing in antifriction material are engaged reciprocally to form the rotational housing and are engaged in two cavities formed in the two opposite faces of a rigid support plate. The support plate and each of the two above-mentioned half-bushings each have a central elongated hole for the introduction, during the mounting step, of a head projecting from the neck of the handle. In this way the disengaging of the head from the elongated holes, after the relative rotation effected at the mounting between the handle, the half-bushings and the plate, is impossible. The means of elastic recovery of the handle comprises a first sliding block counteracted by a spring against which the head formed on the neck of the handle is engaged; a second block acts as a limit stop in the return movement of the handle. Both blocks are connected slidingly to the second half-bushing and are therefore dismountable and interchangeable so that the mounting of the handle in either a right-hand or left-hand position according to the side of the door to be mounted is easily allowed for. The anchorage of the support to the door is facilitated by threaded inserts which are introduced into holes made on the door and tightened by means of screws which cause the insert to expand inside the hole thus creating a permanent, non dismountable anchorage. In a single support, anchorages with different interaxes are possible.
- Other characteristics and advantages of the support for door-and window-handles according to the present invention will be more clearly set forth in the description which follows of one of its possible embodiments, given as an example, but not limitative, with reference to the attached drawings, in which:
- Figure 1 shows an exploded side view of the support for handles of doors, windows and the like according to the invention;
- Figure 2 shows a support according to the invention and relative handle assembled and viewed from the side of a user;
- Figure 3 shows a view of the support of figure 2 not mounted on a door, viewed from the direction opposite to that in figure 2;
- Figure 4 shows a sectional view according to arrows IV-IV of figure 3;
- Figure 5 shows a front view of a handle to be mounted on a support according to the invention;
- Figure 6 shows a view of a section effected according to arrows VI-VI of figure 3;
- Figure 7 shows a view of a section effected according to arrows VII-VII of figure 3;
- Figure 8 shows a plan view in the direction of arrow VIII of figure 1 of a first half-bushing of the support according to the invention;
- Figures 9 and 10 show in the respective directions of arrows IX and X of figure 1 of a second half-bushing of the support according to the invention.
- With reference to figures 1, 5, 8, 9 and 10 a support according to the invention for an
opening handle 1 of a door, window and the like comprises arigid plate 2 withcavities 2a and 2b wherein a first half-bushing 3 and a second half-bushing 4 are engaged. More precisely the half-bushing 3 presentsprojections cavity 2a formed in theplate 2 in order to prevent tangential displacements with respect to the plate whereas the half-bushing 4 is shaped to enter cavity 2b with precision. The half-bushings projections plate 2 to form a cylindrical seat of rotation for aneck 8 extending from theend 1a of thehandle 1. The half-bushings head 11 which projects from theneck 8 of thehandle 1 and presents twoprojections neck 8. Also in theplate 2 aslot hole 12 is provided for the introduction of thehead 11 and has a circular central part for the introduction of thesemicylindrical shell portions bushings slot holes bushings plate 2 respectively, have a form which allows the introduction of thehead 11 of thehandle 1 but does not allow disengaging after thehandle 1 has effected a relative rotation of 90° with respect to them, whereby theprojections first block 13 with which aspring 14 is engaged and is provided with aprotrusion 15 having a T-shaped transversal section able to engage with acorresponding guide 16 made in the half-bushing 4. Anotherguide 16 is created on the opposite side of the half-bushing 4 and is able to engage with aprotrusion 17 also having a T-shaped transversal section made in ablock 18. - The support according to the invention also comprises a
protective cover 19 having ahole 20 for its introduction onto thehandle 1 and of the same form as the first half-bushing 3, as well asteeth 21 shown on the internal sides of thecover 19 itself for engaging withcorresponding notches 22 made on the corresponding external faces of theplate 2. Finally means of anchorage are provided for comprising threadedinserts 23 havingsquared heads 24 andshanks 25 with internally threadedends 25a and acentral part 25b having thin walls. Thesquare heads 24 of theinserts 23 are able to engage with arectangular groove 26 made on theface 2a of theplate 2. On the groove 26 a couple of throughholes 27 is also made, each couple formed by two intersecting parallel holes and having a flared opening, as can be seen in figures 1 and 3. - With reference to the above-mentioned figures, the mounting of the
handle 1 in the support according to the invention is effected as follows: thehead 11 of thehandle 1 is introduced into thehole 9 of the first half-bushing 3 and is turned by 90° with respect to it. The half-bushing 4, to whichblocks shaped protrusions guides 16, is then introduced into the cavity 2b of theplate 2 together with thespring 14 which engages inblock 13. Then thehead 11 ofhandle 1 is introduced intoslot hole 12 of theplate 2 and intoslot hole 10 of the second half-bushing 4. After thisintroduction 1, a second rotation of 90° is imposed to thehandle 1 in order to prevent the disengagement of thehead 11 from theholes projections holes - With reference to figures 3, 4, 6 and 7, the
projection 11a of thehead 11 of thehandle 1 is inserted between thesecond block 18 and thefirst block 13, causing a displacement of theblock 13 in the direction of compression ofspring 14 so that theprojection 11a, during the above-mentioned 90° rotation, comes in contact with it, as shown with a dashed line in figure 3, and arranges itself definitively in the position indicated with a continuous line in the same figure. - The support according to the invention is therefore ready to be mounted on a
door 28 by means of the threadedinserts 23 andscrews 29, as shown in detail in figure 7. Theinserts 23 are arranged so that thesquared head 24 inserts itself in thegroove 26, and afterwards thescrews 29 are introduced into theholes 27 of theplate 2 and their ends are screwed into theinserts 23 without effecting a forced grip. At this point the support complete with handle, screws and inserts is moved close to thedoor 28 on whichholes 30 have been drilled in advance, placing the support so that theinserts 23 enter saidholes 30. Once the introduction has been completed, the fastening of thescrew 29 which screws into the threadedshank 25a of theinsert 23 is carried out and the forced traction effected causes the thin wall of the portion of theshank 25b to bend. Theinserts 23 can not turn about their axis because theirsquared heads 24, being engaged in thegroove 26, do not allow said rotation. Consequently a mountable permanent forced connection is created betweeninserts 23 and thedoor 30, whereas the support for thehandle 1, or alternatively theplate 2, can be easily unscrewed for any necessity by means of thescrews 29. Once the anchorage of the support to thedoor 28 is completed, theprotective cover 19 is applied making thehandle 1 pass throughhole 20 and pressing thecover 19 on theplate 2 until theteeth 21 slip into thenotches 22. - The connection between the
handle 1 and the lock, which is not shown and is applied to thedoor 28, is made by a prismatic pivot which is also not shown and is housed inhole 8a coaxial toneck 8 of thehandle 1 whereby, imparting a downward rotation to thehandle 1, the opening of the lock, as well known, is automatically commanded. - With reference to figures 2 and 3, during the rotation which commands the opening of the door the
projection 11a ofhandle 1 pushes downward theblock 13 which is spring loaded 14 so that, thehandle 1, when released, returns to a horizontal position. The length of thespring 14 in resting position would tend to cause theprojection 11a to exceed the horizontal position, but this is prevented by theblock 18 which functions as a limit stop and assures an absolutely horizontal position to thehandle 1 when not in use, preventing oscillations Y around said position. - With reference to figures 6 and 7, during the rotation of the
handle 1, theneck 8 is engaged within the cylindrical shell formed by the fitted portions of theshells bushings handle 1 about its axis. With further reference to figure 6, theneck 8 is delimitated on one side by thehead 11 and on the other side by ashoulder 1a, coincident with the attachment end of theneck 8 to thehandle 1. Thehead 11 and theshoulder 1a during the rotation slide against the corresponding sides respectively of the second half-bushing 4 and the first half-bushing 3 whereby the rotation of thehandle 1 is totally guided without possibility of oscillation or vibration and with the single possibility of turning about the axis of the handle itself. - The support according to the invention can be provided for already assembled in its components and from it the handle can be dismounted easily for coloration or surface treatments to be carried out successively; it is also possible to convert the support for the handle from "right-hand" mounting to "left-hand" mounting on a door by simply dismounting the
handle 1 from its support and interchanging theblocks handle 1 cannot be dismounted from the support when the support is anchored to the door and the handle is engaged in the lock. This is because locks do not allow in general a rotation greater than 30° and therefore theprojection 11a remains constantly engaged against theblock 13, which returns the handle to the horizontal position after it has been released. By disengaging the support from the door it is however possible to dismount the handle imparting a rotation greater than 45° whereby, as illustrated in figure 3, theprojection 11 pushes theblock 13 downward until reaching the position indicated with a dashed line, then it frees itself from theblock 13 allowing the rotation up to the completion of the 90°, after which it can easily be extracted by way of slot holes 10 and 12 respectively from the half-bushing 4 and theplate 2. - The remounting of the handle is easily effected as indicated above.
- Thanks to the presence of
holes 27 obtained by two intersecting drillings, the same support can be used when the interaxis has two different values. Since in Europe the two standardized and widespread interaxes are of 43 and 50 mm., the support according to the invention can be used with said interaxes for almost all applications. The fixing operations become greatly simplified and using a standardized drilling jig which executes theholes 30 on the door and mounting the support according to the invention as indicated above, a considerable amount of time by those who must carry out said mounting can be saved. The possibility of inverting the handle allows for the right or left mounting of said support without the need of two supports respectively "right" and "left". The support according to the invention, presents therefore multiple aspects which render the mounting quicker and easier and determine a precise and secure manoeuvrability of the handle.
