WALL LOCK DEVICE, ASSEMBLY COMPRISING THE WALL LOCK DEVICE AND BUILDING COMPRISING THE ASSEMBLY

Description

[0001] According to a first aspect, the present invention relates to a wall lock device arranged for locking a modular wall element to a positioning and fastening device.

[0002] According to a second aspect, the present invention relates to an assembly comprising the wall lock device according to the first aspect of the present invention.

[0003] According to a third aspect, the present invention relates to a building comprising an assembly according to the second aspect of the present invention.

[0004] DE 93 17 237 U1 relates to a partition wall element of a movable partition wall, with an extendable and retractable locking element for locking the partition wall element in the direction of movement, characterized by a worm drive which drives the extendable and retractable locking element during its extension and retraction movement.

[0005] The wall lock device is arranged for locking a wall element, preferably a modular wall element, to a positioning and fastening device, said wall lock device comprising an angular transmission, said wall lock device further comprising:

• a wall lock actuation arrangement provided with in input element of said angular transmission and an actuation element arranged for rotating said wall lock actuation arrangement about a virtual actuation axis for actuating said angular transmission;
• a wall lock locking arrangement provided with an output element of said angular transmission and a wall locking element arranged for locking said wall lock device via said wall locking element to said positioning and fastening device, wherein said wall lock locking arrangement is arranged such that said wall lock locking arrangement is allowed to rotate about a virtual locking axis between a first angular position and a second angular position and wherein said wall locking element is moveable along said virtual locking axis, via actuation of said angular transmission through said actuation element, when said wall lock locking arrangement is in said first angular position for realising said locking.

[0006] Within the context of the present invention an angular transmission is to be understood as a transmission wherein a rotation axis of an input element of the angular transmission encloses an angle different from 180 degrees with a rotation axis of an output element of the angular transmission. Preferably, the rotation axis of the output element encloses an angle of substantially 90 degrees, preferably a right-angle transmission, with the rotation axis of the input element. In an embodiment the angular transmission may comprise a bevel gear.

[0007] In an embodiment of the wall lock device, said angular transmission comprises a worm drive provided with a worm screw and a worm gear, wherein said input element of said angular transmission is formed by said worm screw and said output element of said angular transmission is formed by said worm gear.

[0008] The present invention at least partly relies on the insight that an angular transmission, such as a worm drive, may beneficially be deployed for actuating a wall lock element. An angular transmission allows for providing only one actuation element for rotating the wall lock element about the virtual locking axis and for moving the wall lock element along the virtual locking axis. This is beneficial for allowing a constructor to lock the wall element in a relative practical manner to the positioning and fastening device. By rotating the wall lock element about the virtual locking axis the wall lock element may be positioned in a predetermined angular position related to the first angular position. The predetermined angular position may for instance correspond to a position wherein the wall lock element may perform a locking action onto the further element such as the positioning and fastening device, whereas in the second angular position, no such locking action may be realised. Instead, the second angular position may be used for example for allowing to position the wall lock element at least partly in a recess provided in the positioning and fastening device. Once the wall lock element is in the first angular position, the actuation element may be further deployed for realising said locking by moving the wall lock element along said virtual locking axis.

[0009] Moreover, the self-braking characteristic of the worm drive may beneficially be applied for maintaining the wall lock element in a locked position. This is beneficial for avoiding the need to provide further locking means for maintaining the wall element locked to the positioning and fastening device.

[0010] A further advantage of the wall lock device according to the present invention is that the actuation element may be used for unlocking said wall element. To this end, the actuation element is rotated about said virtual actuation axis in a direction of rotation opposite to the direction of rotation applied when realising said locking. When bringing the wall lock device from the locked condition into the unlocked condition the wall lock element is firstly moved along said virtual locking axis due to a rotation of the actuation element about the virtual actuation axis. Once, a friction force between the wall lock element and the positioning and fastening device is below a predetermined level, the wall lock element is moved from the first angular position to the second angular position due to actuation of the actuation element.

[0011] In this regard, it is beneficial if said wall lock device comprises a wall lock device housing arranged for fastening said wall lock device to said wall element.

[0012] Preferably, said wall locking element is provided outside said wall lock device housing and said locking is realised, in use, by clamping said positioning and fastening device between said wall locking element and said wall lock device housing.

[0013] Preferably, said wall lock device is provided with a rotation limiting arrangement arranged for limiting said rotation of said wall lock locking arrangement between said first angular position and said second angular position.

[0014] It is advantageous if said rotation limiting arrangement comprises a cam that is attached to said wall lock locking arrangement and blocked for rotation relative to said wall lock locking arrangement and wherein said rotation limiting arrangement further comprises a first end stop for blocking rotation beyond said first angular position.

[0015] In this regard, it is beneficial if said cam is provided between said wall locking element and said worm gear. This is beneficial for allowing to realise a relative compact wall lock device.

[0016] Preferably, said first angular position and said second angular position enclose an angle in the range of 70 and 140 degrees, preferably 90 degrees.

[0017] According to the second aspect, the present invention relates to an assembly comprising a wall lock device according to the first aspect of the present invention, said assembly further comprising said wall element and said positioning and fastening device, wherein said wall element is locked, by said wall lock device, to said positioning and fastening device.

[0018] Embodiments of the assembly according to the second aspect correspond to embodiments of the wall lock device according to the first aspect of the present invention.

[0019] The advantages of the assembly according to the second aspect correspond to the advantages of the wall lock device according to the first aspect of the present invention presented previously.

[0020] Preferably, said assembly comprises a plurality of said modular wall elements, wherein said modular wall elements comprise a first interface arrangement at a first side of said modular wall element and a second interface arrangement at a second side of said modular wall element, wherein said first interface arrangement and said second interface arrangement are each provided with at least one of:

• a fluid connector arranged for receiving, via said modular wall element, a fluid, wherein said fluid connectors are mutually communicatively coupled for fluid flow;
• an electrical connector arranged for receiving, via said modular wall element, an Alternating Current, AC, mains signal, wherein said electrical connectors are mutually communicatively coupled;

wherein said first interface arrangement and said second interface arrangement are arranged such that a first interface arrangement of a first modular wall element of said plurality of modular wall elements interfaces with a second interface arrangement of a second modular wall element of said plurality of modular wall elements and wherein at least one of said fluid connectors and said electrical connectors of said first modular wall element and said second modular wall element are connected, wherein each of said modular wall elements at a third side thereof are provided with a positioning and fastening device receiving recess, wherein a fastening arrangement of said positioning and fastening device is received in said positioning and fastening device receiving recess.

[0021] The present invention relies at least partly on the insight that realisation of known assemblies having walls comprising electrical wiring and/or ducting for gas or water generally requires realising a wall that is free from utilities such as electrical wiring and/or ducting for gas or water and subsequently rework said wall for integrating said utilities in said wall. The required reworking of the wall is a relative cumbersome activity that may add to the building time for building the building. Moreover, the reworking may add additional cost thereby making the building relatively expensive.

[0022] Alternatively, a less attractive wall may be realised by simply placing the electrical wiring and/or ducting for gas or water on an outer surface of the wall, thereby leaving the electrical wiring and/or ducting for gas or water in sight of persons present in the building. Though placing the utilities on the outer surface of the wall may be relative time effective as compared to reworking the wall, placing the utilities may add to the building time for building the building.

[0023] By providing a modular wall element provided with fluid connectors that are mutually communicatively coupled for fluid flow and/or with electrical connectors that are mutually communicatively coupled a direct integration of the utilities in the wall, without the need for reworking the wall or without the need for placing the utilities on the outer surface of the wall, may be realised thereby allowing to realise a relative attractive wall in a less cumbersome manner.

[0024] By providing the modular wall element with the first and second interface arrangement a relative large wall may be realised in a relative practical manner while realising a direct integration of the utilities in the wall. During installation the interface arrangements of neighbouring modular wall elements may be coupled thereby realising that utilities present in the neighbouring modular wall elements are communicatively coupled. This is beneficial for realising that the utilities may extend along the full length of the wall.

[0025] Providing said modular wall element at a third side thereof with a positioning and fastening device receiving recess and receiving the positioning and fastening device in the positioning and fastening device receiving recess is beneficial for allowing said modular wall element, via the positioning and fastening device, to be fixated to the floor. By providing the positioning and fastening device receiving recess the outer appearance, in use, of the modular wall element may be relatively unaffected by the fixation via the positioning and fastening device.

[0026] Within the context of the present invention the electrical connector may in addition, or alternatively, be arranged for receiving a Direct Current (DC).

[0027] Preferably, said wall elements are provided with a wall lock device receiving space and a wall lock device that is provided in said wall lock device receiving space and arranged for locking said wall element to said fastening arrangement of said positioning and fastening device, wherein said wall element is locked, by said wall lock device, to said fastening arrangement of said positioning and fastening device. Receiving the wall lock device, by the modular wall element, is beneficial for allowing said modular wall element, via the wall lock device, to be fixated to the positioning and fastening device. By providing the wall lock device receiving space the wall lock device may be provided, at least partly, in the modular wall element thereby allowing realisation of a visually attractive wall.

[0028] It is beneficial if said positioning and fastening device comprises:

• said fastening arrangement fastened to said wall element;
• an elongated base extending in a longitudinal direction, said elongated base comprising a fastening arrangement receiving space partly receiving said fastening arrangement, wherein said fastening arrangement receiving space is dimensioned such that said fastening arrangement is movable in said fastening arrangement receiving space;
• a clamping element pivotably connected to said elongated base and arranged such that in a first position of said clamping element said fastening arrangement is movable in said fastening arrangement receiving space and in a second position of said clamping element said fastening arrangement is clamped between said clamping element and said elongated base, wherein said clamping element is maintained in said second position by said wall element.

[0029] By providing the fastening arrangement and the fastening arrangement receiving space, a wall element that is fastened to the fastening arrangement may be positioned relatively accurately relative to the floor by moving the fastening arrangement in the fastening arrangement receiving space. This is beneficial for allowing to achieve a predetermined position of the wall element relative to the floor. Once the predetermined position of the wall element is achieved the wall element may be clamped, by the clamping element and the elongated base, for maintaining the wall element in the predetermined position.

[0030] In this regard, it is beneficial if said elongated base and/or said fastening arrangement are made from extruded profiles, preferably extruded profiles made from aluminium. Extruded profiles are beneficial in this regard for realising a relative straight wall in a practical manner.

[0031] According to the third aspect the present invention relates to a building comprising an assembly according to the second aspect of the present invention and a floor, wherein said elongated base of said positioning and fastening device is fastened to said floor.

[0032] Embodiments of the building according to the third aspect of the present invention correspond to embodiments of the assembly according to the second aspect and the wall lock device according to the first aspect of the present invention.

[0033] The advantages of the building according to the third aspect of the present invention correspond to the advantages of the assembly according to the second aspect and to the advantages of the wall lock device according to the first aspect of the present invention presented previously.

[0040] A positioning and fastening device 101 is arranged for positioning and fastening a wall element 303, preferably the modular wall element 1, to a floor 305 for realising the wall of the building 401. The positioning and fastening device 101 comprises a fastening arrangement 103. The fastening arrangement 103 is arranged for fastening to the wall element 303 and/or the modular wall element 1. To this end the modular wall element 1 is provided with a positioning and fastening device receiving recess 39 in frame element 11 thereof for receiving, in use, the fastening arrangement 103 of the positioning and fastening device 101.

[0041] The positioning and fastening device 101 comprises an elongated base 105 extending in a longitudinal direction L. The elongated base 105 comprises a fastening arrangement receiving space 107. The fastening arrangement receiving space 107 is arranged for partly receiving, in use, said fastening arrangement 103.

The fastening arrangement receiving space 107 is dimensioned such that said fastening arrangement 103 is movable in said fastening arrangement receiving space 107 before said fastening arrangement 103 is fastened to said elongated base 105.

[0042] The positioning and fastening device 101 further comprises two clamping elements 109 that are each pivotably connected to the elongated base 105. The clamping elements 109 are provided with a protrusion 113 that, when connected to said elongated base 105, extents at least partly in said longitudinal direction L. The elongated base 105 is provided with a clamping element receiving space 117 for receiving said protrusion 103 and thereby pivotably connecting the clamping elements 109 to the elongated base 105. Each of the clamping elements 109 is further provided with a clamping organ 115 that, when connected to said elongated base 105, extents at least partly in said longitudinal direction L. The protrusion 113 and clamping element receiving space 117 are arranged such that in a position wherein said clamping organ 115 is substantially perpendicular to the elongated base 105 a removal of the clamping element 109 is possible by lifting the clamping element 109 relative to the elongated base 105. By aligning the clamping organ 119 substantially parallel to the elongated base 105 the fastening arrangement 103 may be clamped between the clamping organ 119 and the elongated base 105. In other words, the clamping elements 109 are arranged such that in a first position of the clamping elements 109 the fastening arrangement 103 is movable in the fastening arrangement receiving space 107 and in a second position of the clamping element 109 the fastening arrangement 103 is clamped between the clamping element 109 and the elongated base 105. The clamping elements 109 are further arranged for, in use, being brought in the second position by placing the modular wall element 1 on a side of the clamping elements 109 facing away from the elongated base 105. The positioning and fastening device 101 may optionally be provided with interface organs 111 for providing an interface between the modular wall element 1, the elongated base 105 and the clamping elements 109. The interface organs 111 are supported on a virtual flat plane V formed by the clamping elements 109 and the elongated base 105.

[0043] The positioning and fastening device 101 further comprises a floor attachment arrangement 102 for attaching a floor 305 to said positioning and fastening device 101.

[0044] Wall lock device 201 comprises a housing 203. Housing 203 is provided with a first housing part 205 and a second housing part 207 that are arranged for being connected to each other via fastening elements 209 and thereby form a housing space for housing elements of the wall lock device 201. The second housing part 207 is provided with further fastening elements 211 for allowing the wall lock device 201 to be fastened to an element of the building 401 such as the modular wall element 1 or wall element 303. The modular wall element 1 and the wall element 303 may be provided with a wall lock device receiving space 41 for receiving the wall lock device 201.

[0045] Wall lock device 201 is arranged for locking to the positioning and fastening device 101 and thereby allowing an element of the building 401 such as the modular wall element 1 and/or wall element 303 to be locked to the positioning and fastening device 101. The wall lock device 201 comprises a worm drive 213 provided with a worm screw 215 and a worm gear 217. The worm screw 215 is provided as part of a wall lock actuation arrangement 219. The wall lock actuation arrangement 219 further comprises an actuation element 221. The actuation element 221 is arranged for rotating of the wall lock actuation arrangement 219 about a virtual actuation axis A for actuating the worm drive 213. In an alternative embodiment of the wall lock device 201, the worm drive is replaced by a bevel gear.

[0046] The worm gear 217 is provided as part of a wall lock locking arrangement 223. The wall lock locking arrangement 223 further comprises a wall locking element 225 that is arranged for locking said wall lock device 201, via said wall locking element 225, to said positioning and fastening device 101. The wall lock locking arrangement 223 is arranged such that said wall lock locking arrangement 223 is allowed to rotate about a virtual locking axis B between a first angular position and a second angular position.

[0047] The rotation of the wall lock locking arrangement 223 is limited, between said first angular position and said second angular position, by a rotation limiting arrangement 227 of the wall lock device 201. The rotation limiting arrangement 227 comprises a cam 229, a first end stop 231 and a second end stop 233. The cam 229 is attached to said wall lock locking arrangement 223 and blocked for rotation relative to said wall lock locking arrangement 223. The cam 229 is blocked for rotation relative to the wall lock locking arrangement 223 by providing the cam 229 with a surface contour that is arranged to provide a form-locked connection with a locking axis 235 of the wall lock locking arrangement 223. The cam 229 is movable along said surface contour in a direction of said virtual locking axis B. Movement of the cam 229 relative to the housing 203 in the direction of the virtual locking axis B is avoided, or at least greatly limited, by guide elements and a worm gear adaptor 239. The guide elements provide a barrier to movement of the cam 229 at a side of the cam 229 facing the wall locking element 225. The worm gear adaptor 239 provides a barrier to movement of the cam 229 at a side of the cam 229 facing away from the wall locking element 225. The movement of the cam 229 along the surface contour may be realised by screwing a nut 237 and/or the worm gear adaptor 239 onto the locking axis 235. The locking axis 235 is provided with a screw thread (not shown) arranged for cooperation with the nut 237 and/or the worm gear adaptor 239. In a first embodiment of the wall lock device 201 a screwing action of the nut 237 causes a change in distance between the nut 237 and the wall locking element 225. The worm gear adaptor 239 provides an interface between the worm gear 217 and the nut 237 for transferring a rotation of the worm gear 217 to the nut 237. In this embodiment the worm gear adaptor 239 may be movable relative to the worm gear 217 and/or the nut 237 in the direction of the virtual locking axis B. Alternatively or in addition, the worm gear adaptor 239 may be provided with screw thread for cooperation with the screw thread provided onto the locking axis 235. In this alternative embodiment, the worm gear adaptor 239 is arranged for driving the cam 229 along said surface contour in the direction of said wall locking element 225 beyond a position that may be achieved with the nut 237. To this end the worm gear adaptor 239 is provided with a protruding wall piece 240 that overcomes a distance between the screw thread provided on the worm gear adaptor 239 and the cam 229.

[0048] The first end stop 231 and the second end stop 233 are provided as an integral part of the housing 203. The second housing part 207 of the embodiment according to the figures comprises rib organs forming the first and second end stops 231 and 233. The locking axis 235 comprised by the wall lock locking arrangement 223 is moveable along said virtual locking axis B. Operation of the worm drive 213 through actuation of the actuation element 221 may result in the cam 229 to contact the first end stop 231. Once the cam 229 is in contact with the first end stop 231 a further actuation of the actuation element 221 in a direction of rotation that is identical to the direction of rotation performed for realising that said cam 229 to be in contact with the first end stop 231 will cause the locking axis 235 to move such that the locking element 225 is moved towards the worm screw 215 of the worm drive 213. By movement of the locking element 225 relative to the housing 203 a distance between the locking element 225 and the housing 203 is reduced allowing to clamp a further element of the building 401 between the locking element 225 and the housing 203 for realising locking by the wall lock device 201.
