Description

guard

The invention relates to a protective grid, in particular for children or pets, according to the preamble of claim 1.

The design patent US D626,660 S describes a protective grille which can be clamped by means of an adjustment of lateral link mechanism between the posts of a door frame. For this purpose, jaws, which are arranged on vertical side parts, created on the door frame. The side parts are each connected via two links with a central grid part. A vertical movement of the grating part relative to the side parts leads by means of the links to an increase in the respective distance between the side parts and the grille part, whereby jamming in the door frame is achieved. The side part is moved in a stable Übertotpunktlage respect to the handlebars and held there by means of stops on the handlebars.

It is the object of the invention to provide a protective grid, which has an improved security.

This object is achieved according to the invention for a protective grid mentioned above with the characterizing features of claim 1. Due to the releasable locking of the steering gear by means of the locking member a simple protection against opening is achieved for example by a toddler. For example, can be achieved by this that two different opening movements must be performed by an operator to remove the barrier member from the opening can. The opening may be, for example, a door opening or also the passage to a staircase, eg between a wall and a banister.

Under a link mechanism according to the invention is in particular a simple four-bar linkage to understand, such as a side panel as the first vertical link, which is connected by means of two links with the barrier member as the fourth link. When pivoting such a steering gear distances between the links are changed, so that a simple us safe fixing can be achieved in the opening. The determination can be done by jamming or caulking on sides of the opening, such as door jamb. In particular, holders of the opening-side link can cooperate with receptacles attached to the opening.

In a generally preferred embodiment of the invention, the linkage can be locked by movement of the barrier member from an open, upper position down into the holding position. This allows a particularly simple closing movement and handling of the protective grid. In particular, it can be held about with one hand, inserted into the opening and spent by simply depressing locking the locking member in the holding position.

In a particularly preferred embodiment of the invention, the locking member is unlocked by a first opening movement, in which the barrier member is moved from the holding position down to a lower end position. After the unlocking of the locking member can then generally in a subsequent, second opening movement, which is different from the first opening movement is the complete solution of the Barnereglieds out of the opening. In a possible, but unnecessary detail design, the first opening movement of the holding position can lead to a second holding position in which the locking member is already unlocked, but still set in the opening.

In a preferred refinement, a dead center position of the link mechanism is overrun in the course of the first opening movement. The Übertotpunktlage the steering gear in conjunction with a suitable stop the adjustment can easily cause a second holding position, especially in conjunction with elastic restoring forces.

A simple mechanical realization of a protective grid according to the invention can take place, for example, in that the blocking member comprises a movable, in particular spring-loaded latch, which can be latched into a latch when the holding position of the steering gear is reached. Preferably, but not necessary, the bolt is releasably lockable by means of a bolt holder in a prestressed position. In the locked position, for example, a second opening movement take place, in which the barrier member is pulled upwards, wherein the link mechanism pivots back accordingly. The locking of the bolt thereby prevents the unwanted blocking of e.g. in the stop position.

A particularly effective function of the locking member can be achieved ereicht in a simple manner, if the bolt is guided during a movement of the steering gear at least partially on a slide track. The slide track can, depending on the requirement and movement section, for example, a trap, such as in the form of a Undercut, and / or a sliding edge for pushing away and locking the bolt include.

Generally, it is provided that a downward movement of the barrier member can be limited by a releasable stop member. As a result, for example, a controlled reaching the holding position can be simplified. In a preferred detail design while a solution of the stop member by an operator with the foot can be actuated. This results in additional security before being actuated by a toddler.

In an expedient development of the invention, an indicator is provided, preferably for displaying a state of the blocking member. This allows for better controlled operation and increases safety.

In a particularly preferred detailed embodiment of the invention, it is provided that on both sides of the barrier member each one of the link mechanism is provided. As a result, a symmetrical structure is achieved, and the individual link transmission can be designed narrow construction.

In an alternative embodiment, it is also possible that the link mechanism is provided on only one side of the barrier member. Further advantages and features of the invention will become apparent from the embodiments described below and from the dependent claims.

Embodiment of FIG. 1.

The protective grid shown in Fig. 1 comprises a rigid, extensively extended barrier member 1 in the form of a grid with upper and lower cross braces 1 a, 1 b and these connecting bars 1 c.

In general, a protective grid according to the invention may also comprise a barrier member without bars, for example in the form of a plastic surface which is in particular transparent. The Barnereglied 1 is connected in each of its four corner areas with a respective handlebar 2. The two links of one side of the barrier member are hinged to a side part 3 in the form of a vertically oriented rod. The link 2, the rod 3 and the barrier member thus form on the left and right sides of the barrier member 1 each have a link mechanism 4 in the form of a four-bar linkage. The side parts 3 each have two adjustable retaining screws 3a with heads 3b, which extend in the horizontal of the side members 3 away and adjustable in length. The retaining screws 3a can each be supported against a non-illustrated structure of a stationary opening, for example posts of a door frame. In this case, the heads 3b preferably interact with receptacles (not shown) fastened to the stationary structure. The recordings can be formed, for example, in a known manner in the manner of pockets open on one side, into which the heads 3b are suspended, for example, from above, before the protective grid is closed.

Alternatively or additionally, the heads 3b may be provided with an elastic buffer, by means of which a jamming can take place directly on the door jamb or a similar structure. By moving the barrier member 1 in the vertical direction relative to the side parts 3, which are placed for example on the ground, a pivoting of the four four-bar linkages 4. This is, starting from an open position of FIG. 3, the horizontal opening width of the four joints 4 is increased , which basically allows jamming between the stationary structures in an expanded position of the linkage. In that regard, the function of the Grid according to the invention in about the prior art, for example according to US D626,660 S.

In the present case, a releasable locking of the link mechanism 4 in a holding position by means of a locking member 5. The locking member 5 comprises a respective integrated in the handlebars 2 mechanism. In the present embodiment, a structurally identical locking member is integrated in all of the four links 2 of the protective grid. It may also be provided in an alternative embodiment that z. B. a locking member is integrated only in one of the two links 2 on one side.

The mechanism of the locking member 5 is present, but not necessarily formed predominantly of plastic castings. It comprises two handlebar shells 2 a, 2 b of a link 2 and a block 6 which can be screwed to the adjacent side part 3. The block 6 has a first opening 6 a into which a bolt 7 is inserted and guided in a linearly movable manner. The latch 7 is supported by a spring 7 a kraftbeaufschlagt against the side part 3. In the block 6, a second opening 6b is provided, which is oriented perpendicular to the first opening 6a and crosses them. In the second opening 6b, a latch holder 8 is inserted, which is subjected to force by means of a supported against the block 6 spring 8a in the direction of the first opening. A front edge of the bolt holder 8 can thus snap in a suitable position of the movable bolt 7 in a groove 7b of the bolt 7, so that the bolt 7 is held in this position or releasably locked.

The bolt holder 8 protrudes with laterally projecting pin 8b from the opening 6b. The pins 8b protrude into slot-like recesses 2e in side walls of the handlebar halves 2a, 2b and are guided in these. The ends of the web-shaped recesses 2e have the function of drivers, by means of which the bolt holder 8 is pulled against the force of the spring 8a from the aperture 6b upwards from a certain angular position of the link 2, so that the bolt holder 8 from the groove 7b of the bolt 7 disengages and releases the latch 7.

An end edge 7c of the bolt 7 abuts at least in the released position of the bolt 7 to a slide track 9 and is guided on this. The slide track 9 consists in this case of two mirror-symmetrically identical halves, which are each formed as a lateral projection of the same material integral with the handlebar halves 2a, 2b.

A first section 9a of the slide track runs in the course of a pivoting movement of the four-bar linkage 4 or link 2 substantially equidistantly with respect to the bolt, so that the bolt 7 protrudes maximally in this path section and the latch bolt 8 is disengaged (see eg state in FIG and Fig. 1 1). A second section of the guide track 9 has a catch or undercut 9b, wherein the bolt 7 snaps over the catch after passing over a ramp, see position in Fig. 6 and Fig. 9. The catch 9b therefore forms a trap for the latch 7. Nach snapping over the catch 9b, the bolt can no longer slide in the opposite direction on the slide track 9 and is blocked in this direction. This corresponds to a first holding position of the locking members 5 of the link mechanism. 4

In the first holding position (FIGS. 1, 6, 9), hinges 2c, 2d of the link 2 are still oriented toward the opening side of a dead center position. In Fig. 9, this is approximately recognizable by the fact that the right, the barrier member arranged pivot 2d slightly above a horizontal through the left, located on the side part 3 pivot 2c is located. A force acting laterally on the retaining screws 3 a, in particular an elastic restoring force, therefore generates a retro-rotating moment in the links 2, which presses the bolt 7 against the catch 9 b of the slide track 9.

A third section 9c of the slide track 9 comprises a ramp with a following equidistant track part. Slides the end edge 7c of the bolt 7 in the corresponding pivot angle of the handlebars 2 via the ramp 9c, the bolt 7 is pushed back against the spring force in the direction of the side part 3. In this case, the bolt 7 reaches a position in which the bolt holder 8 engages in the manner previously described in the groove 7b, wherein at the same time the equidistant web part is achieved on the slide track 9.

Furthermore, a releasable stop member 10 is provided on the lower cross member of the barrier member. The stopper member 10 is formed as a simple block, which is hanging suspended and free swinging on a rotation axis 10a. A lower edge of the pad 10 may be suitably rounded. The lower edge of the freely hanging down block 10 is located in the first holding position of the barrier member at ground level or at the level of the lower ends of the side parts 3. Furthermore, in the handlebar halves 2 a, 2 b perforations arranged as a viewing window 1 1, through which a control of Locking member is enabled. Through the viewing window 1 1 z. B. color-marked edge 7d of the bolt 7 are detected when the latch 7 is in a defined position. In this way it can be recognized whether the locking members are in the holding position in a properly locked position. The invention now works as follows:

The starting point is a released position of the protective grid according to FIGS. 3, 8 and 11. It can be z. B. an operator hold the barrier member 1 on the upper cross member 1 a hanging vertically hanging, the side parts 3 by maximum pivoting of the link mechanism 4 by gravity hanging down. Then, the side parts 3, in the present example, the heads 3b of the retaining screws 3a, attached to the fixed structures of the opening to be obstructed, preferably with hanging the heads 3b in shots (not shown). The side panels sit with their lower ends on the floor.

Subsequently, the barrier member 1 is pressed against an increasing elastic restoring force due to the spanning four-bar 4 down until the hanging down stop member 10 touches down on the ground and stops the movement. Due to the design of the slide track 9 while the unlocked latch 7 is briefly snapped over the catch 7b, wherein the hinges 2c, 2d as described above are still in front of a dead center. The elastic restoring forces now press the bolt 7 of the locking member 5 against the also to be assigned to the locking member 5 notch 7b, so that there is an obstruction in a first stop position. Without the blocking effect of the bolt 7, the barrier member 1 would be pushed upwards by the restoring forces. Proper locking is controllable by the indicator described above. If the protective grille is now to be opened or removed from the obstructed opening, the abutment part 10 with the tip of the foot first becomes the operator tipped so that the barrier member can be pushed further down. Then, the barrier member is first pressed down in the course of a first opening movement, wherein a dead center of the joints 2c, 2d is run over. The bolt 7 passes over the third part of the slide track 9c and is pressed by means of the local flank until the latch holder 8 snaps in and prevents the depressed latch 7 from re-dividing. Finally, the block 6 abuts against an upper stop 9d of the guide track 9, which corresponds to a position of the barrier member 1 which is pressed down to the maximum. This position is shown in FIGS. 2, 7 and 10, respectively.

The forces acting on the side parts 3 elastic forces hold the block 6 against the stop 9d, so that this position is stable. It is therefore a second stop position of the protective grid, in which the grid still can not be removed from the opening. In the second holding position, the joints 2c, 2d of the handlebar 2 are in an over-center position in which they are held stable against the stops 9d. This is followed by the operator to make a second opening movement, which consists in an upward lifting of the barrier member. The second opening movement thus takes place in the opposite direction to the first opening movement. In this case, it is first necessary to proceed again against the elastic restoring forces until the dead center position has been overcome a second time. The latch 7 is retained by the snapped latch holder 8, so that it no longer abuts against the catch 7b in the course of the second opening movement. The barrier member can therefore be pulled completely or maximally upwards relative to the side parts 3, so that the position according to FIG. 3, FIG. 8 and FIG. 11 arises again. In the last section of this movement while the bolt holder 8 by stop on the Ends of the recesses 2 e pulled out against the force of its spring 8 a from the groove 7 b of the bolt 7. The thus released latch, which is now relative to the first section 9a of the slide track 9, while snaps a bit forward until his front edge 7c rests again on the slide track 9. As a result, the starting position is completely restored.

FIG. 12 shows a modification of the embodiment described above, in which only one side of the barrier member has a link mechanism 4. On the other hand, the upper cross member 1 a of the barrier member 1 via a rotary joint 12 is directly connected to the vertical side part 3 rotatably connected. The lower cross member 1 b has a substantially horizontal longitudinal slot 13, in which a pin 14 of the vertical strut 3 is guided.

In such an embodiment, the one link mechanism 4 can also be actuated by raising and lowering the barrier member 1, by the pivot joint 12 and the longitudinal guide 13, 14 in the context of mechanical tolerances sufficient compensating movements of the second side part are made possible. A theoretically exact positive guidance of the components to each other is not necessary. It is understood that solutions with only one linkage as in Fig. 12 are conceivable in other modifications. Further, there may be appropriate modifications, such as in the case of the example shown in FIG. There, the barrier member 1 does not consist of a fixed grid part, but is composed of two grid halves 1 d, 1 e, which partially overlap each other. The degree of overlap is variably adjustable, for example, by means of a number of overlapping holes 1 f, are inserted through the retaining screws. So can the Width of the Barnereglieds 1 as the first adaptation to the opening to be obstructed to be changed adjustable. As a more accurate adaptation, as in the first example, the retaining screws 3a can be adjusted in length by means of, for example by means of a lock nut.

In a further modification shown in Fig. 14 may be provided on one side of the protective grid instead of a head 3b of the retaining screws 3a, a hinge member 15 which engages in a corresponding counter-member 16, which at the opening, e.g. a door jamb, is attached. As a result, the open protective grid is not completely removed, but can be opened and closed in the manner of a door.

In general, it is understood that an inventive locking member is not limited to the solutions shown. In an alternative, not shown, the locking member may be formed, for example, as a latching locking latch, which is directly by the operator, for example by an operating button, detachable. In such an embodiment, the first opening movement in the operation of the actuating knob, after which a second opening movement takes place as a lifting of the barrier member. In particular, only one holding position can be present in this embodiment. Similar to the prior art, this holding position may be in an over-center position of the links 2 with respect to the pivots 2c, 2d.

It is understood that the specific features of the individual embodiments can be usefully combined depending on the requirements.
