Description

[0001] The invention relates to an operating handle according to claim 1.

[0002] A handle is typically used to operate a door, allowing access to a room and locking it when needed. The door usually has a door leaf with side panels, which is pivotally mounted in a door frame.

[0003] The operating mechanism typically comprises two stop elements mounted on the sides of the door leaf, each stop element rotatably receiving and / or supporting a handle, such as a doorknob. The doorknobs operate a latch located in a lock case within the door leaf, with the handles connected to each other via a square spindle. When one of the handles is operated, the latch is retracted into the lock case, and the door can be opened.

[0004] Often, the requirement is to prevent the door from being opened, for example, to lock a bathroom or toilet. This is achieved by extending a bolt from the lock case using a separate key or knob, which engages a strike plate in the door frame. If a separate key or knob is not desired, it is possible to block the movement or rotation of the handles. Furthermore, the movement of the handles can be decoupled from the movement of the latch. In both of these latter cases, the latch can no longer be moved and the door cannot be opened. In all cases, every locking or blocking device is equipped with an emergency release mechanism to allow the door to be opened from the outside in an emergency.

[0005] DE 10 2007 030 655 A1 discloses such an operating handle for a door, in which a stop element with a handle is arranged on each of two sides of a door leaf. The handles are connected to a locking mechanism in the door leaf via a square spindle. To block the operation of the handle and thus the opening of the door, a locking device is formed between the stop elements, which blocks any movement of the handle when a locking element is actuated. The actuating element for actuating the locking device is designed as a pivotable element that projects from the end face of a stop element.

[0006] In an operating handle known from DE 10 2017 130 340 A1, a locking device is also provided, which has a release position and a locking position, so that rotation of the handle about the first axis of rotation is blocked. The operating handle also has an actuating mechanism for the locking device, with a sliding element that is displaceable along a circular segment centered about the first axis of rotation, wherein a displacement of the sliding element along the circular segment causes actuation of the locking device.

[0007] One disadvantage of these common operating handles is the relatively large amount of space required for the locking mechanism and its operating device. For example, the separate keyhole escutcheons or a relatively large overall height detract from the appearance of the operating handle. Often, additional drilling is necessary in the door leaf and lock case to accommodate the locking mechanism. This results in high costs, and compliance with required standards may be impossible.

[0008] A door hardware set disclosed in DE 10 2018 129 450 A1 incorporates the locking device and its operating mechanism in the handle and the square spindle. The locking and emergency release mechanisms are thus located on the handle axis, necessitating drilling in and modifications to the square spindle. This results in complex components and high costs. Assembly is very complex. Furthermore, the drilling and recesses in the square spindle weaken the operating mechanism, making it impossible to meet high load limits and standards.

[0009] Furthermore, the assembly of these products is complex and time-consuming. Because the technology is housed in the handle, only tubular handles can be used.

[0010] The object of the invention is to overcome the disadvantages of the prior art and to create an operating handle that, while requiring little space and offering full functionality with a locking device and emergency release, can be manufactured cost-effectively and can be mounted quickly and conveniently on the door leaf. Furthermore, high strength and load-bearing capacity are sought, with particular compliance with applicable standards.

[0011] Features according to the invention are specified in claim 1. Embodiments are the subject of claims 2 to 15.

[0012] According to the invention, an operating handle for a door with a door leaf and side surfaces is proposed, comprising two handles for operating a closing device arranged in the door, a first stop element and a second stop element for the handles, wherein each handle is mounted axially fixed and rotatable about an axis of rotation on or in a stop element, and wherein each stop element has a first cam and a second cam, each having a through-hole, wherein the cams and the through-holes of the first stop element and the second stop element are arranged opposite each other in pairs on the opposite side surfaces of the door in the mounted position, with opposing cams and through-holes lying on a first axis and a second axis respectively, with a locking device having a release position in which rotation of the handles about the axis of rotation is permitted.and which has a locking position in which rotation of the handles about the axis of rotation is blocked, and with an actuating device for the locking device, wherein the actuating device has an actuating element with which the locking device can be moved from the release position to the locked position and vice versa, characterized in that the locking device and / or the actuating device is / are at least partially located in the area of ​​one of the axes.

[0013] The arrangement of the locking and / or actuating device in the area of ​​one of the axes is advantageous in such a way that neither the square pin is weakened nor is an additional bore required. This solves the problem according to the invention and improves upon the prior art.

[0014] Typically, the locking device and / or the actuating device lies at least partially on one of the axes A and / or A'.

[0015] This advantageous design enables compact constructions and avoids large fittings.

[0016] Preferably, the actuating device is formed on or in the first stop element.

[0017] The proposed design of the actuating device on or in the first stop element allows the locking device to be operated with the same hand after the actuating handle has been actuated. In particular, this enables the locking device to be operated with just one finger.

[0018] In another variant, the locking device is formed on or in the second stop element.

[0019] The arrangement of the actuating device and the locking device on different stop elements follows the advantageous idea of ​​a compact design, since neither of the two stop elements needs to be excessively large.

[0020] Typically, the actuating device and the locking device are operatively connected to each other via an actuating element, wherein the actuating element is rotatably mounted about the first axis and / or is displaceable or pivotable relative to the first axis.

[0021] In a further development, the actuating device has at least one transmission element that transmits an actuation of the actuating element to the actuating member.

[0022] Actuating the actuator with just one finger can be further facilitated by roughening its surface or providing it with a non-slip material. In a further advantageous embodiment, the actuator can also incorporate gear ratios to reduce the required force and / or the travel distance in the case of mechanical actuators.

[0023] In another variant, the first stop element has at least one recess and / or a receptacle for the at least one transmission element of the actuating device.

[0024] Typically, at least one transmission element of the actuating device is rotatably mounted about the first axis and / or is displaceable or pivotable relative to the first axis.

[0025] In a particularly advantageous embodiment, at least one transmission element of the actuating device is arranged in the cam / through bore.

[0026] According to a further development, at least one transmission element of the actuating device can be locked in excellent positions with the first stop element.

[0027] Typically, the locking device has at least one locking element which, in the release position of the locking device, allows the rotation of the handles about the axis of rotation, and which, in the locked position of the locking device, blocks the rotation of the handles about the axis of rotation, wherein the locking element is rotatably mounted about the first axis and / or is displaceable or pivotable relative to the first axis.

[0028] According to a further development, the second stop element has at least one recess and / or a receptacle for the at least one locking element of the locking device.

[0029] According to an advantageous embodiment, at least one transmission element of the locking device is arranged in the cam / through bore.

[0030] Typically, the actuating element is operatively connected to the further transmission element of the actuating device and the transmission element of the locking device.

[0031] In one variant, the second stop element has a recess and / or a receptacle for a movement element that is rotatably mounted around the axis of rotation and is connected to the handles in a rotationally fixed manner.

[0032] Typically, with the locking device in the release position, the moving element can rotate around the axis of rotation and, when the locking device is in the locked position, is prevented from rotating by the locking element.

[0033] In a further development, the locking element is arranged in a rotationally fixed manner on a transmission element, wherein the transmission element has a tool holder which is arranged in an opening of the second stop element.

[0034] According to another method, a fastening element is arranged on the stop elements.

[0035] In a particularly advantageous further development, the fastening element is arranged along the second axis.

[0036] Typically, the first stop element has a recess through which the actuating element protrudes and which serves as its guide.

[0037] The use of a guide further simplifies the operation of the actuating device. In a particularly advantageous embodiment, the recess is arranged such that the actuating element engages at least one transmission element with the stop element in both extreme positions. This makes operation with one finger very intuitive and prevents the locking device from unintentionally releasing and / or closing.

[0038] According to one variant, the stop elements are connected by means of plastic nubs, plastic protrusions and recesses as well as clamping contours.

[0039] The inventive principle of simple assembly is achieved through the use of clamp connections. These are quick to assemble and, due to the elimination of additional parts, cost-effective and aesthetically pleasing.

[0040] According to the invention, a door with a door leaf, wherein the door leaf has at least two cam bores, a mortise lock and at least one operating handle is proposed.

[0041] Typically, the door is characterized by the fact that the cam bores run along axes A and / or B.

[0042] In a particularly advantageous variant, the actuating element of the locking device is guided through a cam bore in the door,

[0043] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. The drawings show: Fig. 1 a perspective view of the operating handle, Fig. 2 a view of the operating handle of Fig. 1 from another perspective, Fig. 3 Exploded view of the elements to be assembled, Fig. 4 Exploded view of the components of the first stop element, Fig. 5 Exploded view of the components of the first stop element from another perspective, Fig. 6 Exploded view of the components of the second stop element, Fig. 7 Exploded view of the components of the second stop element from another perspective, Fig. 8 the components of the actuating and locking device shown separately, Fig. 9 Schematic representation of the door.

[0044] In the figures, identical or corresponding elements are designated with the same reference numerals and are therefore not described again unless expedient. Features already described are not described again to avoid repetition and are applicable to all elements with the same or corresponding reference numerals, unless explicitly excluded. The disclosures contained in the entire description are transferable analogously to identical parts with the same reference numerals or component designations. Furthermore, the positional designations chosen in the description, such as top, bottom, side, etc., refer to the directly described and illustrated figure and are to be applied analogously to the new position if the position changes.Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

[0045] Figs. 1 and 2Each figure shows a perspective view of the operating handle 100 from opposite angles. The operating handle has two handles 102 and 102', each rotatably mounted in the corresponding stop elements 104 and 104' about the axis D. The closing device 106 is located on the drop side between the two stop elements and is operated by the operating device 112. In the illustrated embodiment, the operating element 108 is arranged as a sliding element in a recess 110 on the first stop element 104, through which it projects at the end face S, with the recess in turn acting as its guide. Similarly, an opening 130 is arranged on the second stop element 104'.

[0046] In Fig. 3The components are shown as they must be assembled by the end user. The first stop element 104 is attached to the door and connected to the second stop element 104' via a fastening element 170. A handle is inserted through the stop elements using a square pin 135 and secured with another handle on the other side.

[0047] Fig. 4 and 5Figure 1 shows the components of the first stop element in a typical configuration. The static part of the stop element consists of the fitting 107, the middle section 126, and the lower section 150. These are connected by plastic studs 142 and plastic protrusions 144 in recesses 146 and clamping contours 148, as well as a retaining ring 139. To return the handles after actuation, a return unit 127 is arranged on the middle section 126, which returns the handle to its initial position via torsion springs. The middle section 126 also has cams 128.1 and 128.2 with through holes 129.1 and 129.2, which serve for mounting on the door and thus define the first axis A and the second axis B. The actuating element 124 is guided by the cam 128.1 and the through-bore 129.1, which are typically arranged on the falling side.In the illustrated embodiment, the actuating member 124 can be rotated about axis A by the movement of the actuating element 108. The actuating member 108 is positively engaged with a transmission element 114, which is arranged in a recess 105 and on the retaining ring 139. In the illustrated embodiment, the transmission element 114 has an internal toothed ring 122 that meshes with a pinion 116. A sword-shaped handle is fixed to this pinion, and the actuating member 124 is fastened to this handle via the screw hole 129. The guide of the actuating element allows a rotation of approximately 15°, which, due to a gear ratio, preferably 1:6, results in a 90° rotation of the actuating member 124 about axis A. A detent device 136 is also provided on the central part 126. The transmission element 114 has, in addition to the nose 133, also locking lugs 132 which have a locking contour 134.In the extreme positions, this presses a detent 138 inwards, which means that a torque must be overcome when the actuating element 108 is moved.

[0048] Figs. 6 and 7The components of the second stop element are shown in a typical design. The fitting 107', the middle part 126', and the lower part 150' are connected, as with the first stop element, by plastic studs 142 and plastic protrusions 144 in recesses 146 and clamping contours 148, as well as a retaining ring 139'. The middle part 126' also features cams 128.1' and 128.2' with through holes 129.1' and 129.2', which correspond to their counterparts in the first stop element. The locking element 120 is located in the receptacle 101 and / or the recess 103. This locking element is mounted non-rotatably on a transmission element 121 and secured with a clamping sleeve 123. The transmission element has a tool receptacle 131 on its side facing the handle 102`, which protrudes through the opening 130.The locking device can also be operated from this side using a tool, preferably a screwdriver, thus providing an emergency opening mechanism. Furthermore, the central part 126' has a receptacle 137 for a movement element 118 that can rotate about its axis of rotation. In the locked position, this rotation is prevented by the locking element 120.

[0049] Fig. 8 shows in detail the elements of the actuating device and the locking device already described.

[0050] Fig. 9 Figure 1 schematically represents a door 200. This door has a door leaf 210 in which the mortise lock 230 is arranged. Two cam bores 220 and 221 are located next to the central bore. The cam bores run along axes A and B, with A preferably being located closer to the latch.

[0051] The invention is not limited to one of the embodiments described above, but can be modified in many ways.

[0052] For example, the actuating element 108 can protrude laterally from the stop element instead of through the front face S and thus be operated.

[0053] It can be seen that an operating handle (100) for a door (200) has two handles (102, 102') for operating a closing device (230) arranged in the door, a first stop element (104) and a second stop element (104`) for the handles (102, 102'), wherein each handle (102, 102') is mounted axially fixed and rotatable about a pivot axis (D) on or in each of the stop elements (104, 104'). Each stop element (104, 104') has a first cam (128.1, 128.1`) and a second cam (128.2, 128.2'), each having a through-hole (129.1, 129.1', 129.2, 129.2`), wherein the cams (128.1, 128.2 and 128.1', 128.2') and the through-holes (129.1, 129.2 and 129.1', 129.2') of the first stop element (104) and the second stop element (104') are arranged in pairs opposite each other on opposite side faces (215, 215') of the door (200), wherein opposing cams (128.1, 128.1' and 128.2, 128.2') and through-holes (129.1, 129.1' and 129.2, 129.2') are located on a first axis (A) and a second axis (B), respectively. The actuating handle also has a locking device (106) which has a release position in which rotation of the handles (102, 102') about the axis of rotation (D) is permitted, and a locking position in which rotation of the handles (102, 102') about the axis of rotation (D) is blocked. An actuating device (112) for the locking device (106) has an actuating element (108) with which the locking device (106) can be moved from the release position to the locking position and vice versa. In order to reduce the space required for the actuating handle and to shorten the assembly time, the invention provides that the locking device (106) and / or the actuating device (112) is / are located at least partially in the area of ​​one of the axes (A, B).
