Description

The present invention relates to a locking mechanism for locking an opening movement of a second body movably held on a first body, in particular for locking an opening movement of a container lid or a container flap relative to a container according to the preamble of claim 1 and a container.

Snap latches are often used to close container lids that are pivotably held on containers. For example, a spring-loaded hook is mounted on the container lid which, when the container is closed, slides with a sliding edge along a striker plate attached to the container and engages behind it when the closed position is reached.

To open such a snap lock, it must be swiveled back out of the rear grip with the strike plate against the force of the spring, so that the cover can then be opened again.

The problem with such snap locks is that, with such snap locks, the container can be closed in a simple manner by pressing the lid against the container body, but cannot be locked.

For example, an unintentional impact against the container against a spring force of a spring that holds the catch bolt in the rear grip with the strike plate can cause the catch bolt to detach from the rear grip with the strike plate due to inertia, whereby the container is opened unintentionally.

In addition, such snap locks are very susceptible to manipulation, as they can be released with simple aids.

In order to lock such bodies against each other, sliding bolts can be used, which however have the disadvantage that they have to be in an unlocked position during the closing process and have to be actively pushed into a locking position after a container lid, for example, has been pressed onto a container body. An automatic one Locking by simply pressing the two bodies together is therefore not possible.

The object of the present invention is to improve a locking mechanism for locking an opening movement of a second body movably held on a first body in such a way that accidental opening or unlocking of the first body from the second body is prevented even in the event of an impact as described above.

This object is achieved by a locking mechanism with the features of claim 1 and by a container with the features of claim 15.

The inventive with the locking mechanism for locking an opening movement of a second body movably held on a first body, in particular for locking an opening movement of a container lid or a container flap relative to a container, has a bolt arranged on the second body, which during a closing movement is perpendicular to its Longitudinal extension is movable in a guide groove open towards the first body.

The locking mechanism also has at least one roller body spring-loaded by a spring element in a roller body receptacle open to the guide groove, which can be pressed against a spring force from a clamping position protruding into the guide groove into a release position pressed into the guide groove.

The geometry of an entrance area of the rolling element receptacle adjoining the guide groove is designed in such a way that the rolling element can be pressed in a first direction from the clamping position protruding into the guide groove into the release position pressed into the guide groove when the bolt is moved in the guide groove.

After passing the bolt, the rolling element can be pushed back into the clamping position by the spring force of the spring element.

Depression of the rolling element by passing the bolt in a second direction opposite to the first direction is prevented by the geometry of the input area of the rolling element receptacle.

The bolt is mounted displaceably in or on the second body in the direction of its longitudinal extension, the bolt being displaceable in the direction of its longitudinal axis and perpendicular to the direction of depression of the roller body to unlock the second body from the first body.

With such a locking mechanism, a locking of an opening movement of a second body movably held on a first body is effectively prevented in a simple and efficient manner, and a shock movement against the direction of the spring force of the spring element with which the roller body is pressed into the clamping position is also not possible an unlocking leads.

In particular, the separation of the locking direction and the closing direction enables simple locking with, at the same time, reliable locking of the bodies to one another.

Advantageous variant embodiments of the invention are the subject of the subclaims.

According to an advantageous embodiment variant of the invention, the first body has two rolling element receptacles open to the guide groove, each with one rolling element mounted in these, the rolling element receptacles being positioned directly opposite one another in the guide groove.

This further improves the secure locking of the bolt.

The at least one rolling element is preferably spherical, which has a particularly advantageous effect on the low friction with respect to the bolt, which as a result is particularly energy-efficient and can be withdrawn from the locking position into the unlocking position with little effort.

According to a further advantageous embodiment variant, the at least one rolling body receptacle adjoins a receiving groove in the first body in which the spring element is held. This makes it possible to mount the rolling element directly on the spring element.

It is also conceivable to mount the rolling element in a spherical cap carried by the spring element with a radius that is larger than the radius of the rolling element, which leads to a further reduction in the frictional resistance of the rolling element and again significantly increases the efficiency of the overall system.

According to an advantageous development of the invention, the receiving groove adjoining the at least one rolling element receptacle is oriented at an acute angle to the guide groove, one of the legs of the acute angle extending from the angle tip in the direction of the closed end of the guide groove.

As a result, on the one hand, the insensitivity of the locking mechanism to impacts is increased again and, on the other hand, the locking against movement of the second body out of the closed position is ensured.

According to a further preferred embodiment variant, the rolling body receptacle is designed to be concave in a region close to the second body.

In an advantageous development, the area of the rolling body receptacle forms an acute-angled protrusion towards the guide groove.

This development also contributes to the locking against movement of the second body out of the closed position.

According to a further preferred embodiment of the invention, a striker plate unit is arranged on the first body, the striker plate unit having the at least one rolling body receptacle with the rolling body held therein and the at least one receiving groove with the spring element held therein.

This enables a container or the like to be arranged or retrofitted with such a locking mechanism in a simple manner.

It is also conceivable, however, to form the rolling body receptacle and the receiving groove directly on the first body.

According to a further preferred embodiment variant, a closure element receptacle for receiving a closure element with which the spring element is held captive and pretensioned in the respective receptacle groove is connected to an end of the receiving groove remote from the rolling body receptacle.

In a preferred development, the closure element can be variably positioned in the closure element receptacle for setting a pretensioning of the spring element.

According to a further preferred embodiment of the invention, the bolt is connected to an electric motor mounted on or in the second body and is mounted displaceably.

According to a preferred embodiment variant, the bolt and the electric motor connected to it are mounted in a bolt housing fixed on the second body, which, analogously to the striking plate unit, enables simple equipment or retrofitting of such a locking mechanism on a container.

A container with a first body with a bottom and at least one side wall and a second body designed as a cover of the first body and a locking mechanism for locking and unlocking the container is characterized by a locking mechanism as described above.

According to a preferred embodiment variant, the bolt housing is arranged, in particular releasably fastened, on an underside of the second body facing the bottom of the first body.

According to a further embodiment variant, the strike plate unit is arranged, in particular releasably fastened, in the region of a section of a side wall of the first body facing the interior of the first body, which is remote from the bottom of the first body.

In the following description of the figures, terms such as above, below, left, right, front, rear etc. relate exclusively to the exemplary representation and position of the locking mechanism, bolt, rolling element, spring element and the like selected in the respective figures. These terms are not to be understood as restrictive, i.e. these references may change due to different working positions or the mirror-symmetrical design or the like.

In Figure 1 the reference numeral 1 denotes a variant embodiment of a container according to the invention as a whole.

A variant of a generic locking mechanism is arranged on the container 1, which is used to lock an opening movement of a second body 3 embodied here as a container lid relative to a first body 2 embodied as a container body.

The second body 3, designed as a container lid, can be connected to the container body on a side of the container 1 opposite the locking mechanism, for example via a hinge (not shown) so that the container lid is pivotably fixed on the container body.

It is also conceivable to arrange a locking mechanism in each case on opposite sides of the container 1, so that in this case the container lid can preferably be placed vertically on the container body.

As in the Figures 2 to 4 As shown, the locking mechanism has a bolt 4 which is arranged on the second body 3 and which, during a closing movement, can be moved perpendicular to its longitudinal extension into a guide groove 52 open towards the first body 2.

In the embodiment variant shown here, the guide groove 52 is part of a strike plate unit 50 arranged on the first body 2, as shown in FIGS Figures 5 to 7 is shown in detail.

The strike plate unit 50 is designed here as a separate component which can be fastened to a side wall 21 of the first body 2, for example by screwing or gluing.

To enable a screw connection, fastening openings 56 are preferably provided on the strike plate unit 50, through which the screws for fixing the strike plate unit 50 to the first body 2 can be guided.

While the mounting holes 56 in the Figures 4 to 7 The embodiment variant shown are designed as circular fastening bores, the fastening openings 56 are in the Figures 8 to 11 The embodiment variant shown of the strike plate unit 50 is designed as elongated holes.

This makes it possible to compensate for greater position tolerances between the first body 2 embodied as a container body and the second body 3 embodied here as a container lid.

It is also conceivable to mold such a striking plate unit 50 directly onto the side wall 21 of the first body 2.

The locking mechanism furthermore has at least one rolling element mounted in a spring-loaded manner by a spring element 6 in relation to the guide groove 52 5, which against a spring force from a clamping position protruding into the guide groove 52, as for example in the Figures 4 and 6th is shown, can be pressed into a release position pressed into the guide groove 52.

While the rolling elements 5 in the in Figure 4 If the embodiment variant shown is in direct contact with the respective spring element 6, it is also conceivable to arrange a dome with a radius greater than the radius of the rolling element between a respective rolling element 5 and a spring element 6, which leads to a further reduction in the frictional resistance of the rolling element 5 , which enables a movement of the bolt 4 in the direction of its longitudinal extent with extremely little resistance through such a one-point mounting.

In the embodiment variant shown here, the first body 2 or the strike plate unit 50 fastened to it has two such rolling body receptacles 54 which are open to the guide groove 52 and in each of which a rolling body 5 is mounted.

The roller body receptacles 54 are positioned directly opposite one another in the guide groove 52.

The rolling elements 5 themselves are preferably designed as balls.

Barrel-shaped rolling elements would also be conceivable, whereby the rolling elements 5 designed as balls have the particular advantage that they only have a punctiform contact with the bolt 4 to be locked and thus enable the bolt 4 to move in the direction of its longitudinal extension with the application of very little force is.

As further in particular in Figure 4 As can be seen, the geometry of an input region of the rolling element receptacle 54 adjoining the guide groove 52 is designed in such a way that the rolling element 5 when the bolt 4 is moved in the guide groove 52 in a first direction A, shown in FIG Figure 6 , can be pressed out of the clamping position protruding into the guide groove 52 into the release position pressed into the guide groove 52 and is pressed back into the clamping position by the spring force of the spring element 6 after passing the bolt 4.

When attempting to lock the bolt 4 in the guide groove 52 in a second direction B opposite to the first direction A on the rolling element (s) 5 To drive past, this movement is prevented by the fact that the rolling elements 5 are prevented from being pressed in by the geometry of the input region of the rolling element receptacle 54.

The geometry of the input area of the rolling element receptacles 54 is shown in FIG Figure 4 The exemplary embodiment shown is such that a region 541 of the rolling body receptacle 54 that is close to the second body 3, which is embodied as a cover, is concave.

In this case, an edge of this region 541 of the rolling element receptacle 54 adjoining the guide groove 52 encompasses the rolling element 5 so far that the rolling element 5 or the rolling elements 5, when the bolt 4 moves in direction B, in Figure 4 be pressed upwards against the concave inner wall of the rolling element receptacle 54.

An evasion of the rolling elements 5 further in the direction of a receiving groove 53 adjoining the rolling element receptacle 54, in which the spring element 6 is received, is possible in the case of a force exerted on the rolling element 5 by the movement of the bolt 4 in the direction B by the form-fitting receptacle described above of the rolling element 5 in the concave inner wall of the rolling element receptacle 54 is not possible. This region 541 forms an acute-angled protrusion of the rolling body receptacle 54 towards the guide groove 52.

The bolt 4 is mounted displaceably in or on the second body 3 in the direction of its longitudinal extension.

As in the Figures 2 , 4th and 12 to 15 is shown, the bolt 4 is received in a bolt housing 40 in the preferred embodiment shown here. In a side wall 41 of the bolt housing 40, an opening 42 is provided through which the bolt 4 protrudes from the bolt housing 40 and in the direction of its longitudinal extension from one to the Figures 12 and 13 locking position shown in a in the Figures 14 and 15 Unlocking position shown is displaceable.

In order to unlock the second body 3, the bolt 4 can be displaced from the first body 2 in the direction of its longitudinal axis and perpendicular to the push-in direction of the at least one rolling body 5.

To move the bolt 4 in the bolt housing 40, the bolt 4 is preferably connected to an electric motor. The electric motor is preferably also mounted in the bolt housing 40 and can be actuated via an electronic circuit.

In principle, manual actuation of the bolt 4 is also conceivable.

As in the Figures 4 to 7 As is also shown, the strike plate unit 50 has the at least one rolling element receptacle 54 with the rolling element 5 held therein and the at least one receiving groove 53 with the spring element 6 held therein, with two rolling element receptacles 54 with rolling elements 5 and two receiving grooves 53 in the embodiment variant shown here are formed with the spring element 6 held therein on the strike plate unit 50.

The receiving grooves 53 adjoining the rolling body receptacles 54 are aligned at an acute angle to the guide groove 52. The acute angle considered here is oriented in such a way that one of the legs of the acute angle extends from the angle tip along the inner wall of the guide groove 52 in the direction of the closed end of the guide groove 52. The acute angle is preferably between 10 ° and 45 °.

The movement of the bolt 4 perpendicular to its longitudinal axis in the direction A into the guide groove 52 is made possible in a simple manner in that the rolling elements 5 can be pressed in the direction of the receiving grooves 53, since the the force acting on the rolling elements is directed essentially in the direction of the receiving grooves 53.

On the other hand, when the bolt 4 moves in direction B, the force acting on the rolling element (s) 5 through the lateral surface of the bolt 4 acts essentially perpendicular to the direction of the receiving grooves 53, so that the bolt 4 pushes the rolling element (s) 5 against the inner wall the rolling body receptacle 54 presses so that they cannot move in the direction of the receiving grooves 53.

Each of the grooves 53 for the spring elements 6 is followed by a closure element receptacle 55 for receiving a closure element 7, preferably in the form of a screw, which is inserted into a closure element receptacle provided with an internal thread on the ends facing away from the rolling body receptacles 54 55 can be screwed in to hold the respective spring element 6 secured against loss and pretensioned in the respective receiving groove 53.

In the case of the Figures 8 to 11 The embodiment variant shown is the closure element receptacle 55 compared to that in FIG Figure 7 The embodiment shown is designed to be extended.

This makes it possible, depending on the positioning of the closure element 7, to adjust the bias of the spring element 6 variably. In the Figures 8 and 9 which positions the closure elements 7 so that the spring elements 6 are only slightly pretensioned, while in the Figures 10 and 11 the closure elements 7 are positioned so that the spring elements 6 are strongly pretensioned.

The closure elements 7 are preferably designed as screws, in particular as grub screws, which can be screwed into corresponding internal threads of the closure element receptacles 55.

For easy adjustment of the position, i.e. the screw-in depth of the closure elements 7, the closure elements 7 have a head with a tool holder 71, for example a polygonal socket, in particular a hexagon socket, the tool holder 71 via the Figures 9 and 11 The rear opening shown in the closure element receptacle 55 is easily accessible.

This ensures that an opening movement of the second body relative to the first body is locked in the closed position of the two bodies 2, 3 with respect to one another.

In the Figures 12 and 13 the locking mechanism is shown again in the locking position, in which a lifting of the bolt 4 in Figure 12 and Figure 13 is prevented by the above rolling elements 5 upwards.

the Figures 14 and 15 show the release position of the locking mechanism in which the bolt 4 is completely or almost completely retracted into the bolt housing 40 and thus lifting of the second body 3, which is designed here as a cover, with the bolt housing 40 and bolt 4 fastened therein, for example, by actuating the on the second body 3 arranged operating handle 31 is made possible.

In principle, it is also conceivable to mount the bolt 4 on the first body 2 and the rolling bodies 5 mounted in the rolling body receptacle 54 or in the rolling body receptacles 54 on the second body 3.

For example, it is also conceivable to design the first body as a furniture wall and the second body as a furniture door, flap or drawer, on which the above-described bolt housing 40 with bolt 4 or the striking plate unit 50 with roller body (s) 5 are arranged.
