Description

The The invention relates to a closure device in the form of a Hand operated lever lock according to the preamble of claim 1.

Such closure devices have long been known, according to DE 736 640 a multi-part construction is shown. This has a two-part hook part with a hand lever and a clamping hook, which in turn can be fixed to a counter-member formed as a closing hook. In this case, an eccentric pivot pin is provided in the region of the hand lever, with which a locking is effected for the hook parts located in the closed position. In this closed position, however, there is a risk that the parts are loosened by unintentional lever actuation, cause further shocks to release the clamping hook and then opens the box lock on the vehicle body.

Also known are general designs of closure devices in the form of snap closures ( US 2,634,997 ) or closing devices with driving wedge ( DE 668 617 ), wherein the corresponding manually operable operating lever is detected by a clamp lock or a detent position defining spring element so that accidental unlocking or lifting of parts of the closure can be avoided.

In DE 16 91 970 a closure hook is shown, in which an automatic opening during driving is prevented by a self-locking latch is provided on a hook finger of the hand lever. In accordance with DE 18 95 457 shown locking hook of a base plate pivoting hand lever is locked in the region of its handle part in a spring clip, so that then a backup of the system is achieved and an automatic opening of the closure is excluded.

In a locking mechanism according to GB 1 336 034 is a pivot in a profiling receiving retaining lever provided, wherein a cooperating with the pivot pawl is provided with retaining spring for securing the system.

In a bolt lock according to DE 17 03 691 is a hand-operated latch segment inserted into the closing gap of a provided as a counter member Runge. With this construction, unintentional slipping out of the locking segment from a stanchion gap is to be avoided when the vehicle is twisted.

According to a construction in G 81 05 158 a hook closure for side walls of commercial vehicles is designed so that this hook closure is automatically secured when closing and additional safety hooks o. The like. In addition to handling counterparts are dispensable. It is provided that on one of the mutually pivotable parts of the closure device, a latching element and on the other part a corresponding counter element is provided, so that during the displacement in the closed position, these two elements engage each other. In this case, known action mechanisms are proposed with latching elements, which are provided either in the form of a displaceable by a spring ball and a correspondingly round recess on the counter element or in the form of spring strips with a latching nose and a latching notch as a counter element. In each embodiment of these hook fasteners, the hand lever is used as a one-piece component with a correspondingly shaped closure hook profiling, wherein this component is pivotally connected to a base plate in the region of an axle head provided on an axis. To close the system, the hand lever is indeed operated with only one hand, but to unlock a pawl o. The like. Rastprofilierung an additional finger or hand movement in the vicinity of the clamp connection is required.

According to a construction in DE 196 11 914 A1 an angle lever lock is provided, in which a toothed connection as a positive connection forms the safety assembly of the construction. This tooth connection is constructed between a hand lever and a hook part in such a way that they engage in a form-fitting manner and are thus forcibly rotatable together.

The The invention deals with the problem of a closure device in the form of a lever lock in such a way that with low technical effort, the operation both during the production of the closing as well as the open position is simplified, with improved Finger guard an efficient backup of the closed position becomes possible and with few components a cost-effective Construction is achieved.

The Invention solves this problem by a closure device in the form of a lever lock with the features of the claim 1. With regard to further embodiments is based on the claims 2 to 18 referenced.

The closure device in the form of a lever closure for loading flaps o. The like. Vehicle bodies according to the invention is improved in that the built-up of comparatively simple parts assembly for a "real" one-hand operation is suitable. According to the respective Bedi Enphase is both a fixation and a release of the device with securing part by a single gripping and pivoting movement possible, with the aid of a second hand, the confirmation of an additional latch member or the like auxiliary movements are unnecessary.

The as a respective item to be produced lever and hook elements can be in an optimizable combination with the at least a security part in largely variable versions so be dimensioned that different functional units with equipped with user-specific one-hand closures can be. The concept of the "carryable" security part It is aimed that this wear-loaded Part with little technical effort replaceable in the swivel system is integrated and thus a durable closure with easy replaceable components is provided.

In Advantageous design that is in the receiving lug pivoting hook part at the same time as a holder for the Secured part used. As a result, in the area of hook-eye connection formed without additional components an abutment is, with the "automatically" operated security part fixed directly to the eyelet in the securing position can be.

Further Details and advantageous embodiments of the invention result from the following description and the drawing, in which Embodiment of the closure device in the form of a Lever lock is described in detail. In the drawing demonstrate:

1 a schematic side view of the closure device with receiving eye in the closed position,

2 a side view similar 1 with a first opening phase when unlocking the security part,

3 a side view similar 2 with a second phase with complete unlocking of the closure device,

4 an individual representation of the hand lever provided for the assembly,

5 a perspective individual representation of the intended for the assembly hook part,

6 an individual representation of the base plate provided for the closure device,

7 an individual representation of connectable to the hook part securing part, and

8th a perspective view of cooperating with the closure device receiving lug.

In 1 is a total with 1 Shown designated closure device, which in the manner of a lever or box closure in particular on side walls, tailboards or the like. Superstructures 2 is provided on vehicles. Such closure device 1 have one on a base plate 3 pivotally (arrow A) held handle G on. This can be used when closing one of the representations in 1 corresponding secured hook-eyelet connection are formed by, as a stationary receiving lug 4 trained counter member is detected by a hook K and this connection when opening the closure device 1 can be solved accordingly.

The inventive concept of the closure device 1 provides in production-optimized design that this with a hand lever H and a hook part 5 is provided as respective items. These items form one on a common axle 6 held assemblies, in the area a in the sense of the operating directions A at least in phases mitschwenkbares security part 7 is provided.

The synopsis of the sequence according to 1 to 3 resulting opening phases of the closure device 1 illustrates that at a respective operation (arrow A) of the hand lever H, this from its closed position to the area of the eyelet 4 towards a release position is shifted and thereby both the hook part 5 as well as the security part 7 be swiveled accordingly. From a reverse sequence of movements starting from 3 to 1 towards the basic sequence of movements for fixing the hook part results 5 in the eyelet 4 , wherein the security part 7 in turn is swiveled and fixed accordingly.

From these phases it becomes clear that the security part 7 with the hook part 5 and the hand lever H, as a whole, form a functional unit which functions as a one-hand closure and which, without additional hand movements or the like, controls a respective opening or closing of the closure device 1 advantageous "in one go" allows. In the dimensioning of its individual parts, this functional unit is adapted to the fact that the securing part displaceable at least in phases by means of the hand lever H 7 directly in the contour area 8th the eyelet 4 can be supported and thus parts of an additional abutment or the like. Plants are unnecessary for the closed position.

The concept of the pivotable security part 7 is designed so that this on at least partially arcuate with the outer contour 8th the eyelet 4 intersecting trajectory B is displaceable ( 2 ). It is also conceivable that the cooperating as a functional unit parts H and 5 be arranged so that the securing part 7 by an at least phase thrust movement (not shown) in the securing position is movable and can be traceable from this accordingly.

From the above-described sequence of movements of the device 1 it becomes clear that the security part 7 , the hook part 5 and the hand lever H expediently together around the support shaft 6 are pivotable. It can in principle also the security part 7 as one in the area of the axle 6 directly supported and with the parts 5 as well as H mitschwenkbares item be formed (not shown).

In the illustrated embodiment of the functional unit is to relocate the security part 7 a general with 9 designated driver integrated into the system. In addition, in optimal design of the security part 7 this directly with the hook part 5 connected so that these parts of the assembly under the action of the driver 9 are pivotable together.

From a synopsis of the phase according to 3 with the in 1 it becomes clear that the hook part 5 together with the security part 7 by means of the hand lever H in the form of an investment pen 10 provided driver 9 is relocated. In 3 is with 9 ' the starting position of the driver (corresponding to 1 ) and with a trajectory according to a stitch point line B 'becomes the displacement of the driver 9 clarified. This driver 9 lies on the security part 7 permanently so that this according to a trajectory B (in 2 ) from the investment position in the area of the eyelet 4 is solved.

For a load-optimized design of the device 1 is that in 7 as an individual representation apparent - security part 7 formed as a profile body P, which has at least partially elastic property. This profile body P is by means of its connection openings 11 and not shown connecting parts with the hook part 5 screwed, with a holding leg 12 of the profile body P corresponding to a shape approach 13 is fixed ( 5 ). Starting from a forming radius R is the holding leg 12 the profile body P preferably in one piece with a securing leg 14 shaped, in turn, an investment arc 15 having. It is understood that for efficient reception of the loads occurring during the locking or unlocking of the profile body P (for example, in the pivoting phase B or B '), the profile body P in the region of the securing leg 14 or can be made entirely of a spring steel. Based on the water then elastic properties of the profile body P - at least in the region of the securing leg 14 - Is also a "forced" shift to the backup position then possible, if one from the front free end 15 of the profile body P for receiving eye 4 formed guide gap F is provided with a degree of F = 0 or less. By then predetermined contact phase of the parts 4 and 7 this investment position must be overcome and then the front attachment sheet can 15 into the security situation ( 1 ) at the contour area 8th the eyelet 4 "Snap".

Of functional importance for the operation of the closure device 1 is the design of the hand lever H ( 4 ), this being in the area of its the axle 6 encompassing contour 16 with an at least partially radially extending mold recess 17 is provided. The connection position of the components H and 5 according to 1 in synopsis with 4 and 5 clarifies that in the area of this mold recess 17 of the hand lever H on the hook part 5 shaped radial investment profile 18 intervenes. Here are the mold cavity 17 and the investment profile 18 so matched to each other, that respective the mold cavity 17 radially limiting contact surfaces 19 and 19 ' of the hand lever H in predetermined pivotal positions on respective radial driving surfaces 20 and 20 ' of the hook part 5 can be applied.

This concept of adjacent and stackable surfaces 19 . 20 respectively. 19 ' . 20 ' is on the respective closing functions or phases in the area of between a nose 5 ' of the hook part 5 and the attachment sheet 15 of the profile body P defi ned guide gap F matched. One is variable variables of the device 1 customizable sizing provided with each one between hand lever H and hook part 5 required swing sector S, S 'can be defined.

According to the size of this pivoting sector S are the radially displaceable and then in pairs abutting contour surfaces 19 . 20 respectively. 19 ' . 20 ' are positioned to each other so that the respective opening or closing position of the hook part 5 and the security part 7 can be optimally influenced. It becomes clear that between the contact surfaces 19 . 19 ' and the driving surfaces 20 . 20 ' the - each the phased free movement of the hand lever H predetermining - swivel sector S can be largely variably sized. The pairs of adjacent contour surfaces 19 . 20 respectively. 19 ' . 20 ' are so angeord net, that these when opening or closing respectively the swivel sectors S and S 'on opposite sides of the support shaft 6 define ( 1 . 3 ).

With the construction described above is achieved that starting from the closed position ( 1 ) when panning (arrow A ', 2 ) of the hand lever H or its driver 9 first the security part 7 with investment bow 15 from its connection position on the receiving lug 4 is solved. Thereafter, in a second pivot phase (A '', 3 ) - in the now central on the hook part 5 or hand lever H the two investment and driving surfaces 19 ' . 20 ' abutting each other - the hook part 5 taken according to the manual operation. It is understood that these two phases are "non-stop" executable in a gripping position of the hand.

In reverse sequence of movements it follows that in the closing phase to be executed first the hand lever H counter to the pivoting direction A "in 3 is freely pivotable (swivel sector S ') and then the security part 7 and the hook part 5 by the now - after passing through the phase position according to 2 - Contiguous contour surfaces 19 and 20 together into the closed position ( 1 ) be relocated or pulled.

The structural design of in 4 to 8th shown items of the device 1 is largely variable, so that it can be made available for user-specific constructions as the respective optimally interpretable kit. The wear-loaded components, in particular the profile body P can be replaced with little effort and the hand lever H can be made variable in the region of the handle G both in thickness and in length. To stabilize the base assembly receiving the pivot assembly 3 ( 6 ) This is with one of the axle 6 (not shown) embraced form approach 22 stiffened, wherein for guiding applied during the pivoting areas of the hook part 5 an additional form approach 23 can be provided.

For one-hand operation of the closure device 1 is also conceivable, the security part 7 to be pivotally held in a hinge region on the hand lever H while the safety part on the one hand by means of an additional gripping lever operable to run so that on the other hand to the hook part 5 the securing position defining guide gap F is formed. In an expedient embodiment of the gripping lever is thereby displaced by means of a compression spring o. The like. Restoring element formed assembly in the spread position and at the same time in this position, the security part 7 secured against unwanted displacement (not shown).
