Description

[0001] The present invention relates to a lever handle bearing for a pair of door or window lever handles according to the preamble of claim 1.

[0002] Standard lever handle bearings are used on doors or windows that are intended to be locked on one side, for example on toilet or changing room doors.

[0003] For example, it is known from DE 10 2018 129 450 A1 to design the handle bearing in such a way that one of the door handles has a locking means in the area of ​​the handle neck, by actuating which the door handle on the opposite side of the door can be blocked from rotating.

[0004] The object of the present invention is to design a lever handle bearing for a pair of door or window lever handles in such a way that, instead of one of the door or window lever handles being blocked, the window lever handle is not disengaged from the closing mechanism of the door. to decouple.

[0005] The problem is solved by a lever handle bearing for a pair of door or window lever handles with the features of claim 1.

[0006] The problem is further solved by a pair of door or window handles with a handle bearing having the features of claim 11.

[0007] The lever handle bearing according to the invention for a pair of door or window lever handles with a handle and a lever neck has two lower rosettes that are rotationally fixed to each other, and each bearing flange is pivotably received in a bearing opening of the lower rosettes about a pivot axis of the door or window lever handles, the bearing flange having on its side facing the door or window lever handle a neck part that can be inserted into an end-face opening of the lever neck, with which the respective bearing flange is positively coupled to the respective door or window lever handle in a pivot direction of the bearing flanges.

[0008] The lever handle bearing further comprises a profile pin rotatable around the pivot axis of the door or window lever handle for actuating a door or window lock, which is positively locked in a through-opening of a first of the bearing flanges in the pivot direction of the bearing flanges.

[0009] In a through-opening of the second bearing flange, a coupling element that can be coupled to the profile pin is mounted in a form-fitting manner in the pivoting direction of the bearing flanges and is displaceable in the longitudinal direction of the pivoting axis.

[0010] On the side of the first lower rosette facing the first door or window handle, an operating element is arranged which is coupled to the profile pin in a rotationally fixed manner.

[0011] The profile pin contains a push rod that can be moved longitudinally along the pivot axis and is coupled to the coupling element and the control element.

[0012] By moving the control element from a coupling position to a non-coupling position, the coupling element can be moved from a position coupled to the profile pin to a position decoupled from the profile pin.

[0013] With such a lever handle mounting, it is possible to decouple the second door or window lever handle from the profile pin and thus from the door or window lock by actuating the operating element, thereby allowing the door or window to be opened only from the side on which the operating element is located.

[0014] Advantageous embodiments of the invention are the subject of the dependent claims.

[0015] According to an advantageous embodiment, the operating element has a cylindrical base body which is mounted on a cylindrical neck piece of the first bearing flange.

[0016] An inner sleeve of the operating element, located against the neck piece, has a recess with a guide contour for guiding a drive pin attached to the push rod. Thus, by rotating the operating element around the pivot axis of the door or window handle, the drive pin and the push rod can be moved longitudinally along the pivot axis.

[0017] This allows the rotary movement to be converted into a linear movement by simply rotating the control element around the pivot axis of the door or window handle, thus enabling the coupling element to be easily disengaged from the profile pin.

[0018] According to an advantageous embodiment, the coupling element is spring-loaded into the coupling position coupled with the profile pin by a spring element arranged in a spring receptacle of the second bearing flange.

[0019] This ensures that when the non-decoupled door or window handle is operated, the decoupled door or window handle unlocks again without further operation of the control element.

[0020] Furthermore, the spring load on the coupling element ensures that the second door handle is only decoupled from the door or window lock by actively decoupling it.

[0021] According to a preferred embodiment, the profile pin and the cylindrical neck piece of the first bearing flange have an elongated hole in which the drive pin is guided.

[0022] This allows the drive pin to be driven directly by the control element.

[0023] According to a preferred embodiment of the push-button bearing according to the invention, an emergency release pin projects from an end face of the operating element facing the first lower rosette, which is coupled to an emergency release unit with an actuating head arranged on the second lower rosette, wherein the operating element can be moved from the non-coupling position to the coupling position by actuating the actuating head.

[0024] With such an emergency release unit, it is easily possible to reconnect the decoupled door or window handle to the door or window lock from the side of the decoupled door or window handle.

[0025] In a preferred embodiment, the emergency release assembly has a pivot bracket with an elongated hole, which is non-rotatably connected to the actuating head and into which the emergency release pin engages, wherein the actuating head is rotatably mounted in the second lower rosette.

[0026] This allows for emergency unlocking of the decoupled door or window handle by turning the operating head.

[0027] According to another preferred design variant, the lower rosettes are covered towards the respective door or window handle by a respective cover rosette with a respective cover housing and a bearing opening.

[0028] In a preferred embodiment, the bearing opening of the first cover rosette has a retaining contour against which the emergency release pin rests when the operating element is positioned in the non-coupling position.

[0029] This allows the immediate re-engagement of the previously decoupled second door or window handle after actuation of the non-decoupled first door or window handle.

[0030] According to a preferred embodiment, the marking is designed as a red color marking that indicates the operating status of the push button bearing.

[0031] The pair of door or window handles for mounting on a door leaf or window frame with a handle pivot comprises a first door or window handle with a grip and a lever neck, arranged on one side of the door leaf or window frame; a second door or window handle with a grip and a lever neck; and a handle pivot that connects the two door or window handles and secures them to the door leaf or window frame. The handle pivot is designed as described above.

[0032] Preferred embodiments are explained in more detail below with reference to the accompanying drawings. They show: Figure 1 is a schematic isometric exploded view of an embodiment of a handle bearing according to the invention, as well as a first and second door or window handle; Figure 2 is a top view of a pair of door or window handles and a handle bearing connecting them, without showing a door or window frame; Figure 3 is a front view of the door or window handle equipped with an operating element; Figure 4 is a schematic isometric partially cutaway view of the handle bearing with door or window handles attached to it in a coupling position of the second door or window handle; Figure 5 is one of the Figure 4corresponding representation in a non-coupling position of the second door or window handle, Figures 6 + 7 are isometric exploded views of the first lower rosette and the first bearing flange, Figures 8 + 9 are isometric exploded views of the second lower rosette, the second bearing flange and the coupling element, and Figure 10 is a schematic isometric view of a variant design of the operating element.

[0033] In the following figure descriptions, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the lever handle bearing, door or window handle, grip, escutcheon, bearing flange, coupling element, and the like as chosen in the respective figures. These terms are not to be understood restrictively; that is, these references may change due to different working positions, mirror-symmetrical design, or similar factors.

[0034] In the Figure 1 Reference numeral 1 denotes a lever handle bearing for a set of two door handles 11, 12.

[0035] The lever handle bearing 1 has two lower rosettes 4, 5 which are rotationally fixed to each other, and each bearing flange 6, 7 which is pivotably received in a bearing opening 42, 52 of the lower rosettes 4, 5 about a pivot axis S of the door or window lever handles 11, 12, and which has on its side facing the door or window lever handle 11, 12 a neck part 61, 71 which can be inserted into an end-face opening 113, 123 of the lever handle neck 12, 122 for positive locking coupling of the respective door or window lever handle 11, 12 in a pivot direction R 1 , R 2 of the bearing flanges 6, 7.

[0036] The lever handle bearing 1 further has a profile pin 8 rotatable about the pivot axis S for actuating a door or window lock, which is positively locked in a through opening 62 of a first of the bearing flanges 6 in the pivot direction of the bearing flanges 6, 7.

[0037] The profile pin 8, in its installed state (not shown here), passes through the door leaf or window frame and is coupled in the central area to a door or window lock (not shown here), whereby the door or window lock is actuated by a rotation of the profile pin 8 about its longitudinal axis.

[0038] For mounting the lower rosettes 4, 5 on the door leaf or the window frame, in the embodiment shown here two screw bolts 16 are provided on the first lower rosette 4, which extend through respective openings of the first lower rosette 4 and can be screwed into respective threaded sleeves 17 arranged on the second lower rosette 5.

[0039] What next in the Figure 1 and 6 to 9 As shown, the bearing flanges 6,7 have respective spring stops 65, 76 which cooperate with a respective spring element 18 and spring stops of the lower rosettes 4, 5 to push the door or window handles 11, 12 back into their starting position after actuation.

[0040] When a door or window handle 11, 12 is actuated, this leads to a rotation of the profile pin 8 about its longitudinal axis and thus to a rotation of the respective bearing flange 6, 7 and with this of the respective spring stop 65, 76.

[0041] This causes the spring element 18 to compress in the direction of rotation, thereby compressing the spring element 10 in the same direction. After actuation, the spring element 18 then pushes the door or window handle 11, 12 back into its preferably horizontal starting position.

[0042] To guide the spring element 10, it is received in an annular spring receptacle 43, 53 of the lower rosette 4, 5. The spring receptacle 43, 53 is preferably formed in one of the side surfaces of the lower rosettes 4, 5 facing away from the cover rosette 2, 3.

[0043] The two bearing flanges 6, 7 are preferably fixed with screws inserted laterally into the handle neck 112, 122 of the first and second door or window handle 11, 12.

[0044] The screw 20 extends into a bore 66, in the first neck part 61, 71 of the bearing flanges 6, 7.

[0045] What next in the Figure 1 , 4 and 5As shown, a coupling element 15, which can be coupled to the profile pin 8, is mounted in a coupling element receptacle 72 of the second bearing flange 7 in a form-fitting manner in the pivoting direction of the bearing flanges 7 and is displaceable in the longitudinal direction of the pivot axis S.

[0046] With the aid of this coupling element 15, the second door or window handle 12 can be decoupled from the first door or window handle 11 by actuating an operating element 13, which is arranged on a side of the first lower rosette 4 facing the first door or window handle 11 and is rotationally fixedly coupled to the profile pin 8, by decoupling the profile pin 8 from the coupling element 15.

[0047] For this purpose, a push rod 9, which can be moved longitudinally along the pivot axis S, is incorporated in the profile pin 8 and is coupled to the coupling element 15 and the operating element 13.

[0048] By moving the control element 13 from a coupling position to a non-coupling position, the coupling element 15 is disengaged from a position coupled to the profile pin 8, as shown in Figure 4 shown, in a position decoupled from the profile pin 8, as shown in Figure 5 shown, movable.

[0049] This is presented in a separate presentation in Figure 10 The operating element 13 shown, in the advantageous embodiment shown here, has a cylindrical base body 131 which is mounted on a cylindrical neck piece 63 of the first bearing flange 6.

[0050] An inner mantle of the control element 13, which abuts the neck piece 63, has a recess 137 formed with a guide track 134, which serves to guide a drive pin 10 attached to the push rod 9.

[0051] By rotating the control element 13 around the pivot axis S, the drive pin 10 and the push rod 9 can be moved in the longitudinal direction of the pivot axis S.

[0052] The guideway 134 indicates, as in Figure 10 As shown, a central dome position 135 is shown, so that the drive pin 10, when in contact with this dome position 135, is positioned maximally in the direction of the first door or window handle 11.

[0053] If the control element 13 is pivoted about the pivot axis S in one of the pivot directions R 1 , R 2 , the drive pin 10 is pressed along the guide track 134 in the direction of the second door or window handle 12 until the control element 13 is rotated so far that the drive pin 10 has reached one of the two uncoupling positions 136.

[0054] In this uncoupling position 136, the drive pin 10 is advanced towards the second door or window handle 12, and thus also the push rod 9, to such an extent that the coupling element 15 is moved from its coupling position, in which the mounting sleeve 151 of the coupling element 15 is placed over an end of the profile pin 8 facing the second door or window handle 12, to its uncoupling position, in which the coupling element 15 is released from the end of the profile pin in the coupling element receptacle 72 in the neck part 71 of the second bearing flange 7.

[0055] In this state, if the first door or window handle 11 is actuated, this only causes a rotation of the profile pin 8, but no rotation of the second bearing flange 7 and therefore no pivoting movement of the second door or window handle 12.

[0056] The coupling element is, as further described in the Figures 4 , 5 , 8 and 9As shown, a spring element 19 arranged in a spring receptacle 73 of the second bearing flange 7 is spring-loaded and pressed into the coupling position coupled with the profile pin 8.

[0057] To prevent the control element 13 from being pushed back into the coupling position by this spring element 19 after actuation by the spring element 151, the uncoupling positions 136 in the guide track 134 of the control element 13 are formed as detent positions which, compared to a position that pushes the drive pin 10 maximally in the direction of the second door or window handle 12, allow the drive pin 10 to slide back slightly in the direction of the first door or window handle 11.

[0058] In order to achieve a simple mechanical coupling of the drive pin 10 to the coupling element 15, the profile pin 8 and the cylindrical neck piece 63 of the first bearing flange 6 have an elongated hole 82, 64 in which the drive pin 10 is guided.

[0059] In order to enable emergency release of the second door or window handle 12 from the side of the second door or window handle 12 in case of need, in the preferred embodiment of the handle bearing shown here, an emergency release pin 133 is provided from an end face 138 of the operating element 13 facing the first lower rosette 4, which is coupled to an emergency release assembly 14 with an actuating head 147 arranged on the second lower rosette 5.

[0060] By actuating this actuating head 147, the control element 13 can be moved from the non-coupling position to the coupling position.

[0061] For this purpose, the emergency release assembly 14 preferably has a pivot bracket 141 which is non-rotatably connected to the actuating head 147 and has an elongated hole 143 into which the emergency release pin 133 engages.

[0062] The actuating head 147 is rotatably attached in the second lower rosette 5.

[0063] In order to enable such an emergency release for both right-hand and left-hand swinging door or window handles 11, 12, it is conceivable to add a second component to the handle bearing in the form of a second pivot bracket 142 with an elongated hole 143 provided in a different position, in order to be able to follow the movement of the emergency release pin 133.

[0064] A polygonal pin 146, coupled to the actuating head 147 and the swivel bracket 141, serves to transmit the rotary motion from the actuating head 147 to the swivel bracket 142. In the embodiment shown here, the polygonal pin 146 is enclosed by two sleeves 144 and 145, the first sleeve 144 being rotationally fixed to the swivel bracket 142, 413, and the second sleeve 145 being rotationally fixed to the actuating head 147.

[0065] When the actuating head 147 is rotated for an emergency release operation, this causes the pivoting bracket 141 to pivot and, by transmitting this rotational movement via the elongated hole 143 and the emergency release pin 133 guided in it, which is attached to the operating element 13, the operating element 13 is rotated back into the coupling position of the operating element 13.

[0066] What's next in Figure 1 As shown, the lower rosettes 4, 5 towards the respective door or window handle 11, 12 are preferably covered by respective cover rosettes 2, 3 with a respective cover housing 21, 31 and a bearing opening 22, 32.

[0067] The bearing opening 22 of the first cover rosette 2 preferably has a retaining contour 23 against which the emergency release pin 133 rests when the operating element 13 is positioned in the non-coupling position.

[0068] Furthermore, as in Figure 1As shown, a marking 24 is provided on the surface of the cover housing 21 of the first cover rosette 2 facing the first door or window handle 11, which is concealed by the operating element 13 in the coupling position of the operating element 13.

[0069] When the control element 13 is pressed into the decoupling position, the marker 24 is visible accordingly and indicates to the user that the second door or window handle 12 is decoupled.

[0070] The marking 24 is preferably designed as a red color marking and indicates the locked state of the second door or window handle 12. Reference symbol list
