FIELD OF THE INVENTION
[0001] This invention relates to an attachment mechanism adapted for attachment of an armor
element to a body to be protected by said armor element.
BACKGROUND OF THE INVENTION
[0002] Armor elements are commonly used to protect a body against various threats, mostly
incoming projectiles. Such armor elements are adapted to dissipate and/or absorb the
kinetic energy of the incoming projectile in order to prevent it from penetrating
the body.
[0003] When it is desired to protect a body, for example, a vehicle, armor elements are
usually mounted onto the exterior/interior of the vehicle and are fastened to become
affixed thereto.
[0004] Mounting of an armor element onto a vehicle is normally performed either by welding
the armor element onto the hull of the vehicle at a location thereon in which protection
is sought or by bolting, where the armor element and the hull of the vehicle are pre-formed
with corresponding bores/threads for receiving therein bolts/screws to attach the
armor element to the hull.
[0005] In the former case, the armor element is affixed to the hull permanently, whilst
in the latter case the armor element is detachably attached to the hull and can serve
as an add-on panel.
[0006] Though not related specifically to the field of add-on armor elements,
US2005008458A discloses a fastening system for removably attaching a first work piece having a
first aperture in biased engagement with a second work piece having a second aperture.
The fastening system includes a receptacle having a housing that forms a chamber.
A cap is attached to the housing by a retainer member and is slidable with respect
to the housing between extended and retracted positions. One or more generally conical-shaped
spring washers resiliently bias the cap toward the extended position with a preload
biasing force. The fastening system includes a fastener having a spiral slot that
is adapted to be inserted into the chamber. The spiral slot is adapted to receive
the retainer member. When the fastener is rotated, the spiral slot of the fastener
slides the end cap from the extended position toward the retracted position and compresses
the biasing members such that the biasing members provide a resilient biasing force
for biasing the second work piece in engagement with the first work piece.
[0007] US3488815 A discloses an attachment mechanism adapted for attachment of two elements with each
other according to the preamble of independent claim 1.
SUMMARY OF THE INVENTION
[0008] 1. According to the invention, there is provided an attachment mechanism (1) adapted
for attachment of an armor element to a body to be protected by said armor element,
said attachment mechanism having a central axis (X) and comprising a first unit (100)
and a second unit (200) which are adapted to engage with each other to provide said
attachment, said first unit comprising a first static member (110) and said second
unit comprising a second static member (210) and a working member (220), one of which
static members is adapted for fixed attachment to said armor element, and the other
is adapted for fixed attachment to said body to be protected, wherein said second
unit being configured for assuming a first, disengaged position, in which said working
member is disengaged from said first unit such that said armor element and said body
to be protected are detached from one another and a second, engaged position in which
a first engagement of said working member with said first unit is provided such that
said armor element and said body to be protected are fixedly attached to one another,
and wherein said working member further comprises a locking member (240) configured
for a second engagement with said first unit to prevent disengagement of said working
member from said first unit, thereby retaining said first unit and said second unit
fixedly attached to one another at said second, engaged position, characterized in
that said first unit further comprises a dynamic member (120) configured for being
dynamically displaceable with respect to said first static member, and wherein said
first static member is configured for engagement with said locking member, whilst
said dynamic member is configured for engagement with the working member of the second
unit.
[0009] The first unit can have an affixing portion for attachment thereof to the body to
be protected, and a mounting portion for attachment thereto of the second unit, in
said engaged position, the locking member being configured for engagement with said
mounting portion.
[0010] Said locking member can be configured for assuming a first, unlocked position, in
which it is disengaged from said mounting portion of the first unit, so that said
working member is free to disengage from said first unit, and a second, locked position,
in which said working member is prevented from disengaging from said first unit. The
second unit can further comprise a biasing arrangement configured for urging said
locking member into said second, locked position.
[0011] The mounting portion of the first unit can have a first engagement section configured
for engagement with said working member and a first locking section configured for
engagement with said locking member, and said locking member can be formed with a
second locking section configured to engage the first locking section at least in
said locked position.
[0012] The first unit can have a longitudinal axis and said first locking section is disposed
at a distance from the affixing portion which is greater than that of the first engagement
section.
[0013] The first locking section of the first unit can be in the form of a locking recess
configured for receiving at least a portion of the second locking section of said
locking member, at least in said second, locked position.
[0014] In the unlocked position, the locking member is configured to assume a plurality
of different orientations with respect to the working member, whilst in the locked
position it can assume only a single orientation which is different of any one of
said plurality of orientations. The design can be such that in said locked position,
said single orientation is visually distinguishable from any one of said plurality
of different orientations of the unlocked position.
[0015] For example, said working member can be formed with a first indication surface and
said locking member can be formed with a second indication surface, wherein in said
locked position, the first indication surface and the second indication surface are
aligned to create a visual indication that the locking member is in said second locked
position.
[0016] According to one example, in said locked position, said first indication surface
and said second indication surface are aligned to be flush with one another. According
to another example, each of said first indication surface and said second indication
surface have an imprint thereon, so that in said locked position, said first indication
surface and said second indication surface are aligned so as to form a combined indicative
image/pattern.
[0017] In addition, said locking member can assume said single orientation only when said
working member is properly engaged with said first unit (i.e. when said second unit
is in said first, engaged position).
[0018] One advantage which can arise from the above design, is that an operator mounting
and attaching the armor element to said body to be protected using the attachment
mechanism can easily identify if the locking member is not in said locked position,
thereby alerting him to the fact that the attachment mechanism is not properly engaged
and locked.
[0019] The locking member can be designed so that displacement thereof from said locked
position into said unlocked position is configured for manual operation, so that it
is prevented from spontaneous displacement between the two positions. In addition,
the design is such that said locking member is externally accessible for an operator.
According to a particular example, the locking member can be configured for being
grasped by said operator and manually displaced between said locked position and said
unlocked position. Furthermore, the locking member, once displaced into the unlocked
position may be used as a handle facilitating revolving of the working member.
[0020] Said first unit can comprise, in addition to said static member, a dynamic member,
wherein said static member is configured for fixed attachment to either of said armor
element and body to be protected, and said dynamic member is configured for being
dynamically displaceable with respect to said first static member.
[0021] According to a specific example, said first static member can be configured for engagement
with said locking member, whilst said dynamic member can be configured for engagement
with the working member of the second unit.

DETAILED DESCRIPTION OF EMBODIMENTS
[0023] With reference to Figs. 1A to 2, there is shown an attachment mechanism generally
designated
1, configured for attachment of an armor element
A (shown Fig. 1C) to a body to be protected
B (shown Fig. 1C). The attachment mechanism
1 comprises a first unit
100 and a second unit
200 configured for mutual engagement with one another. The first unit
100 is configured for fixed attachment to the body
B while the second unit
200 is configured for fixed attachment to the armor element
A.
[0024] However, it is appreciated that an opposite arrangement may be used (i.e. first unit
100 attached to the armor element
A and the second unit
200 to the body
B), so long as the units
100, 200 are configured for mutually engagement with one another.
[0025] In Figs. 1A to ID, the attachment mechanism
1 is shown with the first unit
100 being engaged with the second unit
200, such that the armor element A is fixedly attached to the body to be protected, B.
[0026] With reference being drawn to Fig. 2, the attachment mechanism has a central axis
X, and each of the first unit
100 and second unit
200 has a central axis, so that when the first unit
100 is engaged with the second unit
200, the central axes of the units
100, 200 are aligned with one another and constitute the central axis
X of the attachment mechanism
1.
[0027] The first unit
100 comprises a first static member
110 configured for static attachment to the body to be protected (i.e. without moving
with respect thereto) by a nut
101 and washer
102. The first unit
100 further comprises a dynamic member
120 configured for displacement with respect to the first static member
110, and for engagement with the second unit
200.
[0028] The second unit
200 comprises a second static member
210 configured for static attachment to the body to be protected (i.e. without moving
with respect thereto) by a nut
201. The second unit
200 further comprises a working member
220 configured for displacement with respect to the second static member
210, and for engagement with the first unit
100.
[0029] The working member
220 also comprises a locking arrangement
240 configured for preventing disengagement between the first unit
100 and the second unit
200, when the two units
100, 200 are engaged with one another.
[0030] The arrangement is such that when the first unit
100 and the second unit
200 are mutually engaged, the working member
220 of the second unit
200 is configured for a first engagement with the dynamic member
120 of the first unit
100, and the locking arrangement
240 is configured for a second engagement with the first static member
110 of the first unit, the first and the second engagements being spaced from each other
along the central axis X as seen in Fig. 6A, and explained below in more detail with
reference to Figs. 5A and 6A.
[0031] Turning now to Figs. 3A to 3D, the first unit
100 will now be described (shown in these figures without the nut
101 and washer
102). The first unit
100 is constituted by an affixing portion
AP configured for fixed attachment of the first unit
100 to the body
B, and a mounting portion
MP configured for engagement with the second unit
200.
[0032] The affixing portion
AP is in the form of a stud
111 having thereon a thread configured for threading thereon the nut
101. The stud
111 has a length
L (shown Fig. 3D) which is designed to be greater than the thickness of the body
B, so that when the stud
111 is passed through a designated through-going hole of the hull of the body, it is
long enough to project from the other side of the hull, allowing threading thereon
the nut
101.
[0033] Observing the mounting portion
MP, the first static member
110 comprises a housing
112 having an inner cavity
113 (shown Figs. 3C and 3D), accommodating therein the dynamic member
120. The housing
112 has a first end
112a adjacent the affixing portion
AP and a second end
112b more remote from the affixing portion
AP.
[0034] The housing
112 is formed with two side openings
115 radially opposite from one another, configured for allowing a portion of the dynamic
member
120 to project therefrom. The side openings
115 are axially prolonged so as to have a first abutting end
115a and a second abutting end
115b, so that the second end
115b is axially closer to the affixing portion AP than the first end
115a.
[0035] In addition, the housing is formed, at the second end
112b with a tubular projection
114 configured for engagement with the locking arrangement
240 of the second unit
200. Specifically, the projection
114 is formed with two extensions
116, radially spaced apart from one another to define a central recess
118 configured to receive a portion of the locking arrangement
240.
[0036] With particular attention being drawn to Fig. 3B, the dynamic member
120 comprises a main hub
122 having a tubular shape and being formed therein with a central channel
123 oriented transversely to the central axis
X, and receiving therein a securing pin
124. The length of the securing pin is such that it radially protrudes from the main hub
122. The securing pin
124 is also formed with a central slit
126 providing it with required flexibility in order to insert it into the channel
123 of the main hub
122.
[0037] In addition, the dynamic member
120 comprises a biasing arrangement
128 configured for constantly biasing the main hub (and consequently the securing pin
124) towards the affixing portion
AP of the first unit
100. The biasing arrangement
128 is held in place by a cover plate
127 and retained within the housing
112 by a pressure ring
129 abutting the second end
112b of the housing
112.
[0038] Reverting now to Figs. 3A, 3C and 3D, the arrangement is such that when the dynamic
member
120 is accommodated within the housing
112, the securing pin
124 projects from the side openings
115 of the housing
112.
[0039] In addition, the diameter of the securing pin
124 is smaller than the axial extension of the side openings
115, providing the securing pin
124 with a certain degree of freedom defined by the displacement range delimited by the
abutting ends
115a, 115b of the side openings
115.
[0040] Under the operation of the biasing arrangement
128 (e.g. a compression spring), the securing pin
124 is constantly urged towards the affixing portion
AP, so that, when the first unit
100 is disengaged from the second unit
200, the securing pin
124 abuts the second end
115b of the opening
115 (see Fig. 3C).
[0041] In operation, when the dynamic member
120 of the first unit
100 is engaged with the working member
220 of the second unit
200, the securing pin
124 can axially displace towards the first abutting end
115a, as shown in Fig. 3D. The securing pin 124 may thus assume a first position in which
it is at a distance D1 from the most axially remote point of the AP and a second position
in which it is at a distance D2 from the most axially remote point of the AP,
D2 >
D1. This displacement range allows the first unit
100 of the attachment mechanism
1 to compensate for any tolerance error occurring in the first unit
100 and second unit
200.
[0042] In addition, when the dynamic member
120 is engaged with the working member
220, urging of the securing pin
124 towards the affixing portion
AP by the biasing arrangement facilitates a stronger engagement between the working
member
220 and the dynamic member
120, as will be explained in detail with respect to Figs. 5A and 5B.
[0043] It is understood that since the dynamic member
120 has a certain degree of freedom, it may assume different axial positions with respect
to the housing
112, and consequently, the securing pin
124 may assume different positions with respect to the abutting ends
115a, 115b of the side openings
115 of the housing.
[0044] Turning now to Figs. 4A to 5B, the second unit
200 will now be described in detail. The second unit
200 comprises a second static member
210, configured for fixed attachment of the second unit
100 to the armor element
A, and a working member
220 configured for the above first and second engagements with the first unit
100.
[0045] The second static member
210 is in the form of a tubular ring
212 having a central cavity
214 configured for receiving therein the working member
220. The outer surface of the ring
212 is threaded, allowing threading thereon the nut
201. Similar to the first unit
100, the axial length of the nut is designed to be greater than the thickness of the armor
element
A to which the second unit
200 is attached, so that when the ring
212 is passed through a designated through-going hole of the armor element
A, it is long enough to project from the other side of the armor element, allowing threading
thereon the nut
201.
[0046] The working member
220 is received within the central cavity
214 of the second static member
210, and comprises a locking arrangement
240 articulated thereto, which will be discussed in detail with reference to Figs. 4A,
4B, 6A and 6B.
[0047] The working member
220 has a central axis and a flange
F axially separating the working member
220 into an internal portion
IP configured for the above mentioned first engagement with the first unit
100, and an external portion
EP configured to be accessible by an operator, at which the above mentioned second engagement
with the first unit
100 takes place.
[0048] In addition, the working member
220 is also prevented from disconnecting from the static member
210 via the flange
F being received within a recess
218 formed in an inner surface of the static member
210, and delimited by a pressure ring
229. Furthermore, when the second unit
200 is not in engagement with the first unit
100, the working member
220 is configured for freely revolving within the static member
210.
[0049] Observing the internal portion
IP, the working member is formed with a tubular portion
222 having a central cavity
C configured for receiving therein at last a portion of said first unit
100. The tubular portion
222 is further formed with two channels
224 extending along the perimeter of the tubular body
222. The channels
224 are through-going with respect to the wall of a tubular body
222, so as to allow an element received within the central cavity
C (in the present example the securing pin
124 of the dynamic member
120 of the first unit
100) to protrude through the channels
224 towards the outside of the tubular body
222.
[0050] Each channel
224 has a first end
224a located at an end of the tubular body
222 axially remote from the external portion
EP and a second end
224b located at an end of the tubular body
222 closer to the external portion
EP. The first end
224a is formed with an opening, allowing an element (in the present example the securing
pin
124 of the dynamic member
120 of the first unit
100) to be receive within the channel
224 during axial displacement of the working member
220.
[0051] In addition, each of the channels
224 is formed, at said second end
224b with a recess
226 having an axial extension towards the end of the tubular body
222 remote from the external portion, configured for receiving therein a portion of the
securing pin
124 of the dynamic member
120 of the first unit
100.
[0052] Referring now also to Figs. 6A and 6B, during engagement of the first unit
100 and the second unit
200, the former is fixedly received within the body
B so that the mounting portion
MP thereof protrudes from the body
B, and the latter is fixedly attached to the armor element
A.
[0053] In assembly, the working member
220 of the second unit
200 is aligned so that the openings formed at the first ends
224a of the channels
224 are angularly aligned with the portions of the securing pin
124 projecting from the housing
112 of the first unit.
[0054] Once aligned, the armor element
A may be axially displaced with respect to the body
B, so that the projections of the securing pin
124 are received within the channels
224 of the working member
220. Thereafter, the working member
220 is revolved about the central axis
X of the second unit
200 (which is also the central axis
X of the attachment mechanism and of the first unit
100 since they are all aligned when engaged), in this case in a CW direction, so that
the portions
223 of the tubular body
222 of the working member
220 slide in under the projections of the securing pin
124.
[0055] Revolution of the working member
220 continues until securing pin
124 abuts the second end
224b of the channels
224 of the working member
220. Once the projecting portions of the securing pin
124 have reached the second end
224b, and due to the biasing arrangement
128 urging the securing pin
124 towards the affixing portion
AP, the projecting portions of the securing pin
124 slip into the recess
226 of the channels
224.
[0056] It is understood that since the surface of the recess
226 is more axially remote from the external portion
EP that the surface of the portions
223, the portions In of the securing pin
124 received within the recess
226 are prevented from sliding through the channels
224, and so the working member
220 is prevented from disengagement from the dynamic member
120.
[0057] In addition, since the securing pin is biased by the biasing arrangement
128, it constantly applies a force
T on the portions
223 of the working member
220, thereby further securing the engagement between the first unit
100 and the second unit
200.
[0058] With additional reference being made back to Figs. 4A and 4B, the external portion
EP of the working member
220 is formed with a tubular projection
225 having two extensions
227 radially opposite one another defining a central recess
228 configured for receiving therein the locking arrangement
240.
[0059] The locking arrangement
240 is located at the external portion
EP of the working member
220 and is pivotally articulated to the extensions
228 of the working member
220 via a hinge
245.
[0060] The locking arrangement
240 comprises a locking latch
242 configured for displacing between an unlocked position shown in Fig. 4B and a locked
position shown in Fig. 4A. The locking arrangement
240 also comprises a biasing spring
248 configured for maintaining the locking latch
242 in its locked position.
[0061] Reverting to Figs. 6A and 6B, when the working member
220 of the second unit
200 is fully engaged with the dynamic member
120 of the first unit
100 as described above, the locking latch
242 is configured to assume its locked position in which it is received within the recess
228 of the working member
220, and more importantly, within the recess
118 of the static member
110 of the first unit
100.
[0062] In the locked position shown in Fig. 6B, since the locking latch
242 is received within the recess
118, which is in turn, formed in the static member
110 which is prevented from revolving (being fixedly attached to the body
B), the working member
220 is prevented from revolving about its axis. Thus, as long as the locking latch
242 is in its locked position, the working member
220 is prevented from disengaging from the dynamic member
120 of the first unit
100, thereby keeping the armor element A fixedly attached to the body
B.
[0063] It is noted that the locking latch
242 cannot assume its locked position, i.e. it cannot be received within the recess
118 of the static member
110 unless the working member
220 has completed its revolution about the axis and is properly engaged with the securing
pin
124 of the dynamic member
120. In other words, so long as the recess
118 of the static member is not aligned with the recess
228 of the working member
220, the locking latch
242 will not be able to assume it position.
[0064] It is also noted that in the locked position, an external surface S
1 of the locking latch
242 is nearly flush with an external surface
S2 of the extensions
227 of the working member
200. This orientation of the surfaces
S1 and
S2 is only possible at the locked position of the locking latch
242.
[0065] Thus, when mounting the armor element
A onto the body to be protected
B, an operator performing the mounting can have a clear and visual indication whether
the armor element
A is properly attached to the body
B or not. In other words, if, after mounting, the locking latch
242 is not in a position in which the surface
S1 and
S2 are nearly flush with one another, this should indicate that the working member
220 of the second unit
200 is not properly engaged with the dynamic member
120 of the first unit
100.
[0066] In order to disengage the first unit
100 from the second unit
200 and detach the armor element
A from the body
B, it is first required to manually displace the locking latch
242 into its unlocked position (shown in Fig. 4B), and thereafter revolve the working
member
220 about its axis in a direction opposite to that used during engaging (in this case
CCW).
[0067] Manual displacement of the locking latch
242 can be performed by an operator manually grasping and lifting the locking latch
242 until it reaches a position in which no portion of it is received within the recess
118 of the static member
110. In this position, the locking latch
242 may also be used as a handle facilitating the revolving of the working member
220.
[0068] It should be noted that since the projecting portions of the securing pin
124 are received within the recess
226 and held there via the biasing arrangement
128 of the dynamic member
120, it may be required to apply a certain amount of force in order to cause the projections
to pop-out of the recess and to cause the working member
220 to revolve about the axis.
[0069] In addition, during mounting of the armor element
A onto the body
B using the attachment mechanism
1, the locking latch
242 may be required to be displaced into its unlocked position in order to allow revolution
of the working member
220 with respect to the second static member
200 and the first unit
100.
[0070] At least the majority of the components of the attachment mechanism
1, including the first static member
110, second static member
210, dynamic member
120, working member
220 and locking arrangement
240 can be made of materials having a high ballistic resistance. The ballistic resistance
of the materials can be chosen such that it does not fall short of the ballistic resistance
of the armor element
A attached to the body
B.
[0071] Such materials can have a hardness which ranges between 30 to 80 Rockwell C, more
particularly between 40 to 70 Rockwell C, and even more particularly between 50 to
60 Rockwell C. One example of such a material can be tempered 4130 steel.
[0072] Turning now to Figs. 7A to 8B, another example of the attachment mechanism is shown,
generally designated as
1', and differing from the attachment mechanism
1 in the construction of the locking latch
242' and in the securing pins
124' and
245'.
[0073] In particular, the locking latch
242' is slightly more robust than the latch
242 previously described, and is now formed with a shaped recess
246' which is sized and shaped to receive only the tip of the coil
248'. In particular, instead of two similar extensions
244, the present example has a first, narrow extension
244a' and a second, wide extension
244b'.
[0074] The pins
124' and
245' of the attachment mechanism
1' of the present example are spirally rolled pins as opposed to C-shaped pins
124, previously described with respect to the attachment mechanism
1, thereby providing them with greater structural strength.

bereitzustellen, wobei die erste Einheit ein erstes statisches Element (110) umfasst
und die zweite Einheit ein zweites statisches Element (210) und ein Arbeitselement
(220) umfasst, wobei eines der statischen Elemente zur festen Befestigung an dem Panzerungselement
geeignet ist und das andere zur festen Befestigung an dem zu schützenden Körper geeignet
ist,
wobei die zweite Einheit ausgebildet ist, um eine erste, ausgekuppelte Position, in
der das Arbeitselement von der ersten Einheit ausgekuppelt ist, so dass das Panzerungselement
und der zu schützende Körper voneinander gelöst sind, und eine zweite, in Eingriff
befindliche Position, in der ein erster Eingriff des Arbeitselements mit der ersten
Einheit bereitgestellt wird, so dass das Panzerungselement und der zu schützende Körper
fest aneinander befestigt sind, einzunehmen und wobei das Arbeitselement ferner ein
Verriegelungselement (240) umfasst, das für einen zweiten Eingriff mit der ersten
Einheit ausgebildet ist, um ein Auskuppeln des Arbeitselements von der ersten Einheit
zu verhindern, wodurch die erste Einheit und die zweite Einheit in der zweiten, in
Eingriff befindlichen Position fest aneinander befestigt gehalten werden, dadurch gekennzeichnet, dass die erste Einheit ferner ein dynamisches Element (120) umfasst, das ausgebildet ist,
um dynamisch in Bezug auf das erste statische Element verschiebbar zu sein, und wobei
das erste statische Element für einen Eingriff mit dem Verriegelungselement ausgebildet
ist, während das dynamische Element für einen Eingriff mit dem Arbeitselement der
zweiten Einheit ausgebildet ist.
2. Befestigungsmechanismus nach Anspruch 1, wobei die erste Einheit einen Anbringungsabschnitt
(AP) zur Befestigung desselben an dem zu schützenden Körper und einen Montageabschnitt
(MP) zur Befestigung der zweiten Einheit daran in der in Eingriff befindlichen Position
aufweist, wobei das Verriegelungselement zum Eingriff mit dem Montageabschnitt ausgebildet
ist.
3. Befestigungsmechanismus nach Anspruch 1 oder 2, wobei das Verriegelungselement ausgebildet
ist, um eine erste, entriegelte Position einzunehmen, in der es von dem Montageabschnitt
der ersten Einheit ausgekuppelt ist, so dass das Arbeitselement frei ist, um sich
von der ersten Einheit auszukuppeln, und eine zweite, verriegelte Position, in der
das Arbeitselement daran gehindert ist, sich von der ersten Einheit auszukuppeln,
wobei die zweite Einheit eine Vorspannanordnung (128) umfasst, die ausgebildet ist,
um das Verriegelungselement in die zweite, verriegelte Position zu drängen.
4. Befestigungsmechanismus nach Anspruch 1, 2 oder 3, wobei der Montageabschnitt der
ersten Einheit einen ersten Eingriffsabschnitt, der für den Eingriff mit dem Arbeitselement
ausgebildet ist, und einen ersten Verriegelungsabschnitt, der für den Eingriff mit
dem Verriegelungselement ausgebildet ist, aufweist und wobei das Verriegelungselement
mit einem zweiten Verriegelungsabschnitt ausgestaltet ist, der ausgebildet ist, um
mit dem ersten Verriegelungsabschnitt zumindest in der verriegelten Position in Eingriff
zu kommen.
5. Befestigungsmechanismus nach Anspruch 2, wobei die erste Einheit eine Längsachse aufweist
und der erste Verriegelungsabschnitt in einem Abstand von dem Anbringungsabschnitt
angeordnet ist, der größer als der des ersten Eingriffsabschnitts ist.
6. Befestigungsmechanismus nach Anspruch 3, wobei in der entriegelten Position das Verriegelungselement
ausgebildet ist, um eine Vielzahl von verschiedenen Ausrichtungen in Bezug auf das
Arbeitselement anzunehmen, während es in der verriegelten Position nur eine einzige
Ausrichtung annehmen kann, die sich von jeder der Vielzahl von Ausrichtungen unterscheidet,
und wobei die einzige Ausrichtung visuell von jeder der Vielzahl von verschiedenen
Ausrichtungen der entriegelten Position unterscheidbar ist.
7. Befestigungsmechanismus nach Anspruch 6, wobei das Arbeitselement mit einer ersten
Anzeigefläche und das Verriegelungselement mit einer zweiten Anzeigefläche ausgebildet
ist, so dass in der verriegelten Position die erste Anzeigefläche und die zweite Anzeigefläche
ausgerichtet sind, um eine visuelle Anzeige zu erzeugen, dass sich das Verriegelungselement
in der zweiten verriegelten Position befindet.
8. Befestigungsmechanismus nach Anspruch 3, wobei das Verriegelungselement für einen
Bediener von außen zugänglich ist, so dass er das Verriegelungselement greifen und
manuell zwischen der verriegelten Position und der entriegelten Position verschieben
kann.
