Definitions

• the present invention relates to a key safe-keeping device of the kind defined in the preamble of Claim 1.
• SE,B,8205720-9 (Publ. No. 435 536) (Lassmedjan) describes a key safe-keeping device consisting of a two-part threaded container intended for installation in the entrance door of apartments in apartment blocks between the outside and the inside of the door.
• the container is open towards the inside and is provided with a space for the temporary keeping of the apartment key.
• By rotating the barrel of the lock cylinder with the help of a pass key or master key the container can be closed so that it is inaccessible from the outside.
• the lock cylinder can be removed in the unlocked position, whereby the apartment key is made accessible from the outside.
• FR,A,0 164 288 (Di Maria) describes an arrangement with double lock cylinders which are arranged in parallel alongside one another.
• SE,A,9402471-8 (ASSA) describes a device in which the tubular key-keeping unit on the inside of the cylinder lock incorporates an activation device so arranged as to interact with the carrier device of the cylinder lock in such a way that it can be rotated for the purpose of opening the cylinder lock only after actuation of the activating device from the inside of the unit.
• the activating device may consist of a second cylinder lock, in which case both cylinder locks have a shared carrier device, or their carrier devices are connected to one another.
• the tubular unit is concentric and combined with the anchoring element and partially encloses the latter.
• the relationship may be the opposite, however; that is to say the anchoring element may partially enclose the tubular unit.
• the tubular unit is provided as a rule with an end wall or a bottom, and the anchoring element is reliably secured to the wall, for example embodied therein.
• the tubular unit is open at both ends as a rule, that is to say so that the apartment key can be placed inside the tubular unit from the inside of the door, for example if a service engineer needs to gain entry to the apartment when the occupier of the apartment is not at home.
• the present invention proposes to eliminate this serious shortcoming or drawback of known key safe-keeping devices. This object is achieved in accordance with the invention with a key safe-keeping device of the aforesaid kind and having the characteristic features set forth in the characterizing clause of Claim 1.
• the latching member is able to extend through said hole and engage in the aperture or the hole in the outwardly lying part, wherein relative movement between both parts, for example rotation of the tubular part by means of a suitably designed tool, is essentially prevented.
• the object of the invention is thus realised with the aid of simple means and without costly supplementary devices.
• the anchoring element may be a nut element having a thread for engagement with a corresponding thread on the tubular unit.
• the nut element it is preferable for the nut element to include a flange, preferably an end flange, for engagement with the adjacent lateral surface of the door and for picking up and securing and, when appropriate, for embodying the safe-keeping device in the wall, which in that case will be recessed so as to accommodate the tubular unit.
• a modified key safe-keeping device in accordance with the invention is shown in Claim 3.
• the latching member is received in the outwardly lying aperture or the hole under the influence of the cylinder lock as it is introduced into the tubular unit, that is to say no rotation of the barrel of the lock cylinder is reguired in order to activate the latching member.
• the barrel can nevertheless typically exhibit or typically coact with a latching member for the purpose of attaching the cylinder lock to the tubular unit.
• Fig. 1 is a section through a first embodiment of an inventive key safe-keeping device intended for installation in a door.
• Fig. 2 is a section through a second embodiment of an inventive key safe-keeping device for installation in a wall or a wall element.
• Figs. 3 and 4 are sections through a third embodiment of the inventive key safe-keeping device, wherein the barrel and an additional latching member connected thereto are shown in different positions in the two Figures.
• a key safe-keeping device 1 mounted in a through-penetrating hole in a door 2 and consisting of a tubular unit 3 which is openably closed at one end by a cylinder lock 4 having a lock cylinder 5.
• the lock cylinder includes a barrel or plug 6 having a slot for the insertion of a pass key or a master key 7.
• the tubular unit 3 is concentric and is combined with an anchoring element in the form of a nut element 11 provided with an end flange lla. To this end, the tubular unit 3 has an external thread 3b which interacts with an internal thread lib on the anchoring element. Appropriate adaptation to the thickness of the door in question can be achieved by rotating the tubular unit 3 and/or the anchoring element 11, so as to anchor the tubular in the recess in the door 2.
• a cross pin 16 in the tubular unit 3 supports the lock cylinder 5 with the cylinder lock in its inserted position.
• the barrel 6 of the cylinder lock has a latching device 20 which, when the barrel 6 is rotated by means of the key 7, engages in an aperture 14 in the enveloping or mantle surface of the tubular unit 3.
• the aforementioned aperture 14 is through penetrating, that is to say it consists of a hole in the mantle surface. This hole or aperture 14 in the tubular unit aligns, at least in part, with an aperture or hole 15 in the anchoring element 11.
• tubular unit 3 can no longer be unscrewed from the anchoring element 11 with the aid of a tool.
• the tubular unit is provided at its outer end, in the area of the barrel 6, with an attachment flange 3a which engages with the outside of the door 2 such as to fix the tubular unit 3 to the door in coaction with the flange 11 on the anchoring element 11 engaging with the inside of the door.
• the key safe-keeping device can be covered from the inside of the door by means of a removable cover 23.
• the embodiment illustrated in Fig. 2 is intended for installation in a wall or a wall element 17 and differs from the embodiment illustrated in Fig. 1, amongst other things in that the tubular element, which is designated 3' in Fig. 2, has a bottom or an end wall 3' c.
• the apartment key accommodating space inside the tubular element is thus accessible only from the outside after having removed the cylinder lock 4.
• the two embodiments of the key safe-keeping device correspond to one another in other respects.
• tubular element 3 and 3' may thus instead have an internal thread (not shown) for coaction with an anchoring element (not shown) which is partially enclosed by by said tubular element and which has a corresponding external thread.
• Types of connection between a tubular unit and an anchoring element other than the illustrated screw threaded connections are also possible within the scope of the invention.
• Figs. 3 and 4 illustrate a modified version of the key safe ⁇ keeping device shown in Figs. 1 and 2.
• Another type of cylinder lock designated 4' is used here, wherein the lock barrel 6' interacts with a rotatable latching member 6' a, the sole function of which is to secure the cylinder lock to, and to release it from the tubular unit, here designated 3".
• the tubular unit 3" has an aperture 14' which, with the unit in its installed position, aligns at least partially with an aperture 15' in the anchoring element 11' .
• the aperture 14' has located therein a latching member 21 provided with an inner head 21a, which, when activated by the lock cylinder 5' of the cylinder lock 4' when the cylinder lock is introduced, describes a movement directed radially outwards so that the latching member 21 engages in the external anchoring element 11' and thereby secures the tubular unit 3" against rotational movement relative to the anchoring element.
• An O-ring 25 is fitted into a central recess in the latching member 21.
• the O-ring functions to retain the latching member in its assumed position.
• the latching member is easily removed by manipulating its head 21a, for example with a screwdriver.
• a recess in the tubular unit 3" facilitates this operation.
• this embodiment is also intended to be door-mounted and the anchoring element 11' on the inside of the door is also covered by a removable cover member 23.
