Definitions
- the invention relates to an engagement lock for a container having a pair of locking rings or locking eyelets, said engagement lock comprising first and second members adapted for snap-fit interlocking after the first member has been introduced into a cavity provided in the second member.
- the elongated body of such a prior art lock is a cable or wire which is too flexible, and consequently, this flexible member will yield and be bent if e.g. the stroke of a hammer is used in order to try to insert and interlock it with the other member. Moreover, the individual strands of the wire will be untwisted or loosened during such an attempt of interlocking.
- the engagement lock is opened by cutting the rod-shaped body by means of a strong pair of scissors or shears, e.g. by cutting in one of the annular grooves which are intentional lines of weakness.
- a thief or a person having fraudulent thoughts, e.g. of transporting non legal goods in a container will not use the authorised opening referred to above, since this person does not want the opening and the subsequent closing of the container and the opening and the subsequent closing of the engagement lock to be revealed later on during inspection of the engagement lock.
- a thief or a fraudulent person attempting to transport non legal goods, e.g. drugs, etc in the container will attempt to break the engagement lock and store his "goods" in the container prior to - if at all possible - locking the container again. This person does no want addition or replacement of goods to be revealed later on by inspecting the engagement lock, e.g. by visible crack or other hammering or drilling traces.
- An object of the present invention is to provide an engagement lock which cannot be unauthorised broken by a hammer or by drilling and which engagement lock can only be opened by the intentional authorised opening.
- a feature of the present invention relates to the fact that the provision of the blocking for any unauthorised opening of the lock is provided concealed in the lock itself thereby preventing any unauthorised tampering with the blocking which else could allow a thief or a fraudulent person to successfully convert the lock according to the present invention into a lock of the prior art which does not prevent unauthorised breaking or opening.
- the first aspect relating to an engagement lock for a container having a pair of locking rings, the engagement lock comprising:
- a first member comprising a rod-shaped elongate body defining a first and a second end, and defining an axis in the longitudinal direction of the rod-shaped elongate body, the first end constituting an insertion end defining a surface and a first transversal dimension, and the second end comprising a head defining a second transversal dimension being larger than the first transversal dimension of the insertion end,
- a second member having a cavity defining a third transversal dimension allowing the insertion end to snap-fit interlock with the second member provided the insertion end of the first member being introduced into the cavity, the second member defining an outer, fourth transversal dimension
- the insertion end being provided on the surface with a first number of protruding locking elements extending in the direction of the axis
- the cavity of the second member being provided with a second number of locking recesses for matingly locking and arresting the insertion end to the cavity whereby the first member being locked and arrested to the second member, and
- the second aspect relating to an engagement lock for a container having a pair of locking rings
- the engagement lock comprising: - a first member comprising a rod-shaped elongate body defining a first and a second end, and defining an axis in the longitudinal direction of the rod-shaped elongate body, the first end constituting an insertion end defining a surface and a first transversal dimension, and the second end comprising a head defining a second transversal dimension being larger than the first transversal dimension of the insertion end,
- a second member having a cavity defining a third transversal dimension allowing the insertion end to snap-fit interlock with the second member provided the insertion end of the first member being introduced into the cavity, the second member defining an outer, fourth transversal dimension
- the insertion end being provided on the surface with a first number of locking recesses extending in the direction of the axis
- the cavity of the second member being provided with a second number of protruding locking elements for matingly locking and arresting the insertion end to the cavity whereby the first member being locked and arrested to the second member, and
- the first number being equal to or greater than the second number.
- the provision of the set of protruding locking elements and locking recesses prevent the engagement lock from being unauthorised broken or opened by means of a hammer or by drilling or rotating, and further the presence of the co-operating and mating locking elements and locking recesses concealed within the second member prevents the engagement lock from being converted by tampering from an unauthorised opening non-blocking engagement lock into an unauthorised opening blocking engagement lock which may in some cases be successfully opened by unauthorised breaking or opening the engagement lock by drilling.
- the present invention provides that the engagement lock cannot be broken in a position of the engagement lock, which is concealed by the locking ring of the container.
- the first number is preferably 1-9, such as 2-6, and most preferably 4, and the first and the second numbers are identical.
- the protruding locking elements are preferably equidistantly spaced, allowing the engagement lock to be closed and locked in more than a single mutual orientation between the first and the second members of the engagement lock.
- the first member is preferably provided between its first and second end with a third number of annular grooves perpendicular to the axis of the first member for providing lines of weakness.
- the engagement lock is provided with an identification element rendering it possible later on to detect if the engagement lock has been switched to another engagement lock. For example, prior to shipping or after filling the container it is written down which engagement lock the container is supplied with.
- the identification element of the engagement lock may comprise any coding in visible or readable or invisible or unreadable form e.g. a code which may be read in day light or alternatively only when exposed to e.g. UV-light.
- the identification element may comprise letters and/or integers, or alternatively comprise colour identification comprising one or more colours or alternatively series of digits in combination with or constituting a unique code.
- the identification element may comprise a RFID tag defining a unique code or alternatively include a bar code defining a unique code.
- the information contained or included in the identification element in visible or readable form or alternatively in invisible or unreadable form preferably defines the identity of the manufacturer, a shipping agent, a handling agent or a carrier for identifying the container itself or any combination of the above information.
- the identification element is preferably provided so as to be destroyed or be deteriorated provided an attempt is made of unauthorised opening or breaking open the engagement lock, such as hammering or drilling the engagement lock.
- the identification element consequently, is placed at the exterior of the second member and covering the mayor part of the second member so as to prevent that a thief or a fraudulent person may hold or draft the second member for attempting to open or break the engagement lock without in such an attempt deteriorating or ruining the identification element and thereby revealing that an unauthorised opening has been attempted.
- the head is a conical head, a disc- shaped head, a spherical shaped head or a pyramid shaped head or a combination of a head including the above geometrical or any other relevant geometrical configuration.
- the present invention according to a third aspect of the present invention further relates to a method of locking a container with locking rings comprising the step of providing an engagement lock including anti-rotational elements and preferably implemented in accordance with the above discussed first and second aspect of the present invention such as protruding locking elements and locking recesses.
- Fig. 1 is a perspective and schematic view of a first and presently preferred embodiment of an engagement lock according to the present invention
- Fig. 2 is a perspective and schematic view of the engagement lock shown in Fig. 1 when used according to its intentional purpose
- Fig. 3 is a vertical sectional view of the engagement lock shown in Figs. 1 and 2,
- Fig. 4 is a perspective and exploded view of the engagement lock shown in figs. 1 and 3,
- Fig. 5 is a schematic and sectional view of a part of an engagement lock shown in Figs. 1-4,
- Figs. 6, 7 and 8 are perspective, schematic and partly broken away views of alternative embodiments of the engagement lock.
- Fig. 9 is a perspective and schematic view of the engagement lock shown in Figs. 1- 5 when used for locking together two parts of a container.
- the engagement lock 10 comprises two members 20 and 30 which are adapted to automatic interlocking after the first member 20 which is in the form of a rod-shaped body, has been partly introduced into a cavity of the second member 30.
- the engagement lock 10 is used for locking a container for the transport of goods.
- the first member 20 comprises a rod-shaped elongate body which defines a first end 21 and a second end 22.
- the first end 21 constitutes the insertion end and defines a reduced diameter part as compared to the intermediate part of the first member which intermediate part constitutes a shaft and connects the first end 21 to the second end 22.
- a head 24 of considerably longer diameter than the first end 21 and the intermediate part of the first member 20 is provided.
- the intermediate part or shaft is designated the reference numeral 25 and is provided with circumferentially extending recesses 28 for the purpose of guiding a cutting tool such as a strong scissors or shears which are used for cutting open the engagement lock 10.
- a circumferential recess 23 is provided which serves the purpose of co-operating with a locking ring of the second member 30 in the locking or arresting of the first member 20 relative to the second member 30 as is known in the art per se.
- a set of outwardly protruding locking elements or locking ridges 26 is provided.
- the locking elements or ridges 26 are received in corresponding locking recesses provided at the inner surface of the cavity of the second member 30 as will be described below for preventing the unintentional rotation of the first member 20 relative to the second member 30.
- the purpose of providing the locking elements or ridges 26 cooperating with corresponding recesses at the inner surface of the cavity of the second member 30 is basically to prevent any unauthorised opening of the engagement lock by a thief or a fraudulent person as it has been realised that some of the prior art engagement locks may be unauthorised opened by connecting a drilling machine to the head of the engagement lock and rotate the one member similar to the member 20 of the engagement lock 10 causing the locking between the one member similar to the first member 20 of the engagement lock to be disconnected from its intentional locking to the member corresponding to the member 30.
- the presence of the locking element 26 at the first end or insertion end 21 of the first member 20 co-operating with similarly configurated recesses at the surface of the inner cavity of the second member 30 is contemplated to improve the safety and to dramatically reduce the possibility that a thief or a fraudulent person may gain access to a container which is locked by means of the engagement lock 10 by unauthorised opening of the engagement lock 10.
- Fig. 2 two plates 12 and 14 constituting two co-operating rings of a closure of a container are located juxtaposed one another and the first member 20 of the engagement lock 10 is introduced through a hole or an aperture 30 of the one plate 14 and further through a similar hole or aperture of the plate 12, and from the opposite side of the assembly of the two plates 12 and 14, the second member 30 is joined with the first member 10 as the first end or insertion end 21 of the first member 10 of the engagement lock is introduced into the inner cavity of the second member 30 and causing the first member 20 to lock the second member 30 of the engagement lock 10.
- Fig. 3 the assembly composed of the first member 20 and the second member 30 of the engagement lock 10 is shown in greater details in a vertical sectional view illustrating a metal core 27 of the first member 20 which metal core 27 is covered by a plastics coating of covering 29 which is moulded to the metal core 27 and provides the circumferential recesses 28.
- Fig. 4 the first member 20 of the engagement lock 10 is shown and the second member 30 of the engagement lock 10 is further shown in exploded view disclosing in greater details the structure of the member.
- the second member 30 comprises a metal bushing 31 defining an inner surface defining the above described cavity which surface is designated the reference numeral 32.
- a plurality of recesses 33 are provided serving the purpose of receiving the locking elements or locking ridges 26 of the reduced diameter insertion end 21 of the first member 20 when the first member 20 is locked to the second member 30.
- the second member 30 further comprises a plug 34 which is received within the metal bushing 31 and which supports as evident from Fig. 5 the above-mentioned locking ring 35.
- the second member 30 further comprises, similar to the outer cover 29 of the first member, an outer cover 36.
- a schematic and vertical sectional view of the second member 30 is shown disclosing in greater details the plug 34 and the locking ring 35.
- first and presently preferred embodiment of the engagement lock according to the present invention may be modified in numerous ways by e.g. shifting the locking elements for the first member 20 to the second member 30 and in the alternative provide locking recesses at the insertion end of the first member 20.
- a total of four locking elements 26 and similarly a total of four recesses 33 of the metal bushing 31 are provided, however, in an alternative embodiment, e.g. eight or twelve recesses may be provided in the metal bushing 31 , allowing the first end 21 of the first member 20 to be inserted into the second member 30 in more than four distinct orientations such as eight or twelve distinct orientations.
- the number of co-operating locking elements or ridges and locking recesses of the first and second members 20 or 30 or, alternatively, according to the above described alternative embodiment of the second member and the first member 30 and 20, respectively, may be altered as only a single locking element need to be present for providing the feature characteristic of the present invention of preventing rotation of the first member of the engagement lock relative to the second member of the engagement lock.
- any number of cooperating locking elements or locking recesses may be present such as 2-9 sets, e.g. 3, 5, 7, 8 or as discussed above, preferably a total of 4 co-operating locking elements or locking recesses.
- the geometry of the structure of the two members 20 or 30 of the engagement lock may be modified as for instance the head 24 of the engagement lock may be differently configured as illustrated in Figs. 6-8, as in Fig. 6 a variant of the head of the first member of the engagement lock is shown, which head differs from the above described head 24 in that the head has a conical cross-sectional configuration.
- the head 24" may constitute a plain circular cylindrical plate or further alternatively, as is illustrated in Fig. 8, the head 24'" may constitute a sphere.
- Fig. 9 the intentional use of the engagement lock 10 is shown as the lock is used for locking the plate 14 constituting a bracket of a container to a plate 12 of the same container for locking and sealing the door of the container, and consequently prevent any unauthorised opening of the door of the container.
