The invention relates to a locking arrangement for the latching of a door to a counterpart. The door can, for example, be a pivotable door wing or a sliding door. The named counterpart can, for example, likewise be formed by a pivotable door wing, a sliding door, a door frame or a building wall. Such a locking arrangement in particular serves as a retrofittable additional securing means to latch the rear doors of a delivery vehicle to one another. The locking arrangement is generally made in two parts for this purpose, with the one part being associated with the door and the other part being associated with the counterpart. When using a lock, the two parts can be secured to one another in order hereby to latch the door and the counterpart to one another. Any unauthorized opening of the door is hereby prevented. A hoop lock, in particular a so-called padlock, is suitable as the lock, for example.
Known locking arrangements of the named kind do not always provided the desired stability and security against being broken open or they are undesirably complex in manufacture and correspondingly expensive.
It is an object of the invention to provide a locking arrangement for the latching of a door to a counterpart which has a simple design and can be manufactured cost-effectively and which nevertheless provides high security against being broken open.
This object is satisfied by a locking arrangement which has an upper part and a lower part, with the upper part at least comprising:
Such a locking arrangement is characterized by an upper part and a lower part which can be fastened to the door and to the counterpart—or vice versa. Both the upper part and the lower part have a respective securing section with a securing opening, with the two securing sections being made such that the named openings are aligned in the position of use of the locking arrangement—that is when the door is closed relative to the counterpart. The two securing sections can thus be secured to one another by means of a hoop of an associated hoop lock in order hereby to latch the door and the counterpart to one another. The hoop lock can be covered by means of the cover section in this respect to protect the hoop lock from manipulation attempts. In addition, at least one side section can protect the hoop lock in the position of use of the locking arrangement from the side, in particular in the area of the lock hoop. Since, however, the lock opening is provided at the front-side cover section of the upper part, the major points of attack can already be protected by the cover section simply by covering the lock by means of the cover section of the upper part. The handling for the authorized user is also hereby simplified quite substantially.
The different base sections and side sections as well as the cover section can be formed by plate-like, i.e. flat, metal parts. The base section, the named first side section and the cover section of the upper part can in particular be formed by a single stamped/bent part, that is by a one-piece, folded sheet metal part, or the whole upper part and the whole lower part are even each formed by s single-part sheet metal part which is angled at a plurality of folds. A particularly stable locking arrangement which is simultaneously easy to manufacture and thus cost-effective hereby results.
The named hoop lock can be part of the locking arrangement. The hoop lock is preferably a rotatable hoop lock with a rotatable hoop shaped like the section of a circle. A shallow design of the locking arrangement hereby results despite the advantageous front-side operation (via the key opening at the cover section of the upper part).
An advantage of the invention lies in the fact that generally a commercial hoop lock can also be used, for example, the padlock of the type “Diskus” of ABUS August Bremicker Söhne K G, Wetter, Germany.
A further advantage of the invention lies in the fact that such a hoop lock can be permanently held at the upper part or at the lower part of the locking arrangement such that the lock also remains fastened to the upper part or to the lower part with an open lock hoop, in particular when the respective door is opened and the upper part and the lower part are separated from one another for this purpose. The handling of the locking arrangement is hereby facilitated in a advantageous manner since the associated hoop lock does not always have to be completely released and held or put down by the user, for example, for the latching and unlatching of the arrangement. In other words, the hoop lock can always remain fastened to the upper part or to the lower part—even if it is purchased as a separate article by the user—so that the user only has to take along the key associated with the lock, but not the lock itself if the door should remain unlatched temporarily.
It is preferred in this connection if the hoop lock has a latching mechanism with key retaining. In this case, the key associated with the lock can only be removed from the lock when the latching mechanism—and thus the lock hoop—has been brought into a latching position. The user can thus conclude without any further visual inspection simply from the circumstance that the key can be removed that the upper part and the lower part of the latching mechanism (naturally provided that it is in the position of use) are properly secured to one another. This is particularly advantageous since the cover section of the upper part—as explained—substantially covers the lock and the lock hoop is thus, for example, not easily visible.
Further advantageous and preferred embodiments are named in the dependent claims.
The invention will be explained only by way of example in the following with reference to the drawings.
a shows a perspective view of a first embodiment of a locking arrangement.
b shows the rear side of the upper part of the locking arrangement in accordance with
Elements which are the same or of the same kind are marked by the same reference numerals in the Figures. Folds are shown by thin lines. The contour of hidden elements or of edges is partly drawn as a dashed line.
a and 1b show a first embodiment of a locking arrangement with an upper part 11 and a lower part 13. The upper part 11 is provides for fastening to a door 15 (e.g. a first door wing). The lower part 13 is provided for fastening to a counterpart 17 (e.g. second door wing, door frame or building wall). For this purpose, the upper part 11 has a plurality of fastening openings 21 at a base section 19 through which fastening screws, fastening bolts, fastening rivets or the like can be led. Alternatively, fastening bolts can be permanently fastened, for example welded, to the lower side of the base section 19. In a corresponding manner, a plurality of fastening openings 25 are formed at a base section 23 of the lower part 13. The respective fastening means (fastening openings 21, 25) can also be formed at a respective fastening section which is connected to the base section 19 of the upper part 11 or to the base section 23 of the lower part 13 and is in particular angled, for example for fastening to a corresponding angled wall section.
A first side section 27 at which in turn a cover section 29 is shaped is shaped at the base section 19 of the upper part 11. The cover section 29 has a central key opening 31 for the introduction of a key of a rotatable hoop lock, as will still be explained in the following. A second side section 33 is shaped adjacent to the first side section 27 at the cover section 29 and extends approximately along half the respective side length of the cover section 29. A securing section 35 is in turn shaped at a side edge of this second side section 33 of the upper part 11 and has a securing opening 37 for the introduction of the hoop of the already named rotatable hoop lock. The rotatable hoop lock is not shown in
A third side section 39 is additionally shaped at the cover section 29 of the upper part 11 opposite the first side section 27. Said third side section has a fastening cut-out 41 at its free longitudinal edge for a holding web described in the following. In addition, a fourth side section 43 (shown by a dashed line in
The first side section 27 of the upper part 11 is angled orthogonally in each case with respect to the base section 19 and with respect to the cover section 29 so that the base section 19 and the cover section 29 extend in parallel offset to one another, with the base section 19 and the cover section 29 extending in opposite directions starting from the first side section 27. It is, however, alternatively possible that the base section 19 and the cover section 29 are angled in the same direction starting from the first side section 27, i.e. the base section 19 can also be arranged beneath the cover section 29.
The second side section 33 of the upper part 11 is likewise angled orthogonally to the cover section 29 and the securing section 35 is in turn angled orthogonally to the second side section 33 so that the securing section 35 of the upper part 11 extends substantially perpendicular to the cover section 29, and indeed along the rear side of the cover section 29. The third side section 39 is also angled at a right angle to the cover section and the fourth side section 43 is likewise angled orthogonally to the cover section 29. It must, however, be noted that the receiving space for the already mentioned rotatable hoop lock provided at the rear side of the cover section 29 does not have to be surrounded by side sections at all sides—i.e. not along the total periphery. The side sections 39 and 43 can therefore also be omitted in a simplified embodiment.
A securing section 54 is shaped at the already named base section 23 of the lower part 13, is angled at a right angle to the base section 23 and has a securing opening 47 for the introduction of the already named lock hoop.
In addition, a first side section 49 and a second side section 51 are each shaped orthogonally to the base section 23 at the base section 23 of the lower part 13. The first side section 49 ultimately serves for the closing of the aforesaid receiving space for the rotatable hoop lock. The second side section 51 of the lower part 13 cooperates as a placement aid with the fourth side section 43 of the upper part 11 and serves for the stabilization of the locking arrangement in the position of use.
b shows the rear side of the upper part 11. A rotatable hoop lock 55 is now fastened in the already named receiving space 53 provided at the rear side of the cover section 29. The rotatable hoop lock 55 has a lock body 57 with a cut-out 59. The rotatable hoop lock 55 can be rotatably actuated at the front side (not shown) by means of an associated key (likewise not shown) which is guided through the front-side key opening 31 (
The fastening of the rotatable hoop lock 55 to the upper part 11 takes place by means of a holding web 63. The holding web 63 extends in parallel offset to the cover section 29 of the upper part 11 between the first side section 27 and the third side section 39. It has an anchorage section 65 at one end which engages into an associated cut-out at the first side surface 27 of the upper part 11—and indeed adjacent to the base section 19. The anchorage section 65 can, for example, have a hang-in tongue or a fastening screw. At the other end, the holding web 63 has a wedge section 67, for example, which is jammed at the fastening cut-out 41 of the third side section 39 of the upper part 11. Other kinds of fastening are naturally also possible to hold the rotatable hoop lock 55 permanently (releasably or non-releasably) at the upper part 11.
The operation of the locking arrangement shown will be explained in the following: The door 15 can be pivoted at the height of the counterpart 17 to thereby bring the explained locking arrangement into a position of use. It can be recognized from
Provided that now the rotatable hoop 61 is brought by a corresponding actuation of the rotatable hoop lock 55 into a latching position in which the rotatable hoop 61 passes through the cut-out 59, the rotatable hoop 61 also engages through the two securing openings 37, 47 of the upper part 11 and of the lower part 13 so that the two securing sections 35, 45 are secured to one another and the upper part 11 and the lower part 13 are also secured to one another. The door 15 is thus latched to the counterpart 17.
The rotatable hoop 61 of the rotatable hoop lock 55 is again moved back out of the cut-out 59 for the unlatching of the locking arrangement by a corresponding actuation by means of the associated key so that the two securing sections 35, 45 of the upper part 11 and of the lower part 13 are released again and the upper part 11 can thus be released from the lower part 13.
In the described position of use of the locking arrangement, the cover section 29 of the upper part 11 covers the securing section 35 of the upper part 11 and also the securing section 45 of the lower side 13. In addition, the cover section 29 covers a substantial part of the front side of the rotatable hoop lock 55. In this position of use, the securing section 45 of the lower part 13 now also extends along the rear side of the cover section 29 of the upper part 11. The securing sections 35, 45 of the rotatable hoop 61 of the rotatable hoop lock 55 as well as the lock body 57 are hereby protected from manipulation attempts from the outside.
In the embodiment in accordance with
The explained locking arrangement can be manufactured in a particularly simple and cost-effective manner. Apart from the named rotatable hoop 61 of the rotatable hoop lock 55, no movable parts are namely required, i.e. the different sections 19, 27, 29, 33, 35, 39, 43 of the upper part 11 can be provided in a rigid arrangement relative to one another. The same applies accordingly to the lower part 13 with the sections 23, 45, 49, 51. The handling by the user is hereby also simplified since no movable parts have to be folded over and flipped over one another in a specific order, for example.
Above all, the different sections 19, 27, 29, 33, 35, 39, 43 of the upper part 11 and the different sections 23, 45, 49, 51 of the lower part 13 can be made as plate-like metal sections so that a particularly simple processing is possible and the upper part 11 and the lower part 13 can be made at least in part as a respective one-piece folded sheet metal part. The sections 19, 27, 29, 33, 39 and 43 can in particular form a single stamped/bent part, with the individual sections only being folded over to form a respective adjacent section at the connection line (cf. thinly drawn fold in
A further advantage lies in the fact that the locking arrangement can cooperate with a commercial hoop lock. The rotatable hoop lock 55 can therefore be a fixed component of the locking arrangement. Alternatively, the user can, however, also use the upper part 11 and the lower part 13 in conjunction with another hoop lock of his choice.
Overall, a locking arrangement of high stability and security against being broken open results which can simultaneously be manufactured in a cost-effective manner and can be fastened in a simple manner. The locking arrangement is hereby also particularly well suited for retrofitting at a door 15 and a counterpart 17.
