Description

barrier grid

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

No. 4,645,183 A describes a barrier grille for children in which adjoining segments are connected by means of a rotary joint, wherein the setting of an adjustment angle of the segments is staged by spring-loaded detents. The adjustment angle of the segments can be changed at any time by a designated operating force.

It is the object of the invention to provide a barrier, which has a simple operability by an adult.

This object is achieved according to the invention for an initially mentioned barrier with the features of claim 1. Due to the form-releasable fixability of the segments in the discrete angular positions an adjustment is avoided. In addition, the installation of the grid, for example in the formation of a closed playpen, is simplified.

Overall, the invention also makes it possible to flexibly set up the segments of the blocking grid in as many angular positions as possible and stably.

Under a barrier in the context of the invention, all planar segments are understood, which are suitable for the desired barrier, for example, a small child. This does not only include grids parallel individual bars, but also crossed grids, grid with flat elements or even continuous closed areas in the segments, for example wood panels or transparent or opaque plastic panels.

In a preferred embodiment of the invention, an upper and a lower pivot joint are provided on both the first segment and the second segment. In a preferred detailed design, the upper and lower pivot joints are connected to each other via a strut which is rotatable in the joints. The positive fixing can preferably be provided in one of the joints or in both joints. The strut may form, for example, a grid bar or a planar element of the barrier grid.

In an advantageous embodiment of the invention, the articulated connection has two substantially parallel, spaced apart axes of rotation. As a result, the barrier grid can be folded in a simple manner to a small pack size, in which the adjacent segments are parallel to each other. Preferably, the thickness of a segment may correspond substantially to the spacing of the two axes of rotation. A further advantage of the two spaced axes of rotation is given if each of the axes of rotation by means provided thereon joints in a plurality of discrete pivot positions is releasably fixed, so that a total of a larger number of possible angular positions of the adjacent segments is achieved.

Further advantageously, it may be provided that the first segment and the second segment by means of at least one connector are releasably connectable to each other, wherein in a preferred embodiment of the connector on at least one of the two segments is resiliently form-fitting fixable. This allows the number of segments of the barrier by the operator easily and quickly adapt to a particular use. Particularly preferably, the connector is inexpensively designed as a plug-in molded part, for example made of plastic, in the manner of a clip. To further simplify assembly, the connector may have a symmetrical shape with respect to the two segments. Thus, for example, the segments can be mounted together in a horizontal direction by first providing the clip or connector on one segment and then attaching the other segment to the clip. Suitably, a lower and an upper clip for connecting two segments are provided in each case.

Generally, the articulated connection preferably comprises a swivel joint with a first and a second swivel joint part, wherein a form-locking, releasable blocking of the swivel joint takes place by means of an axially directed displacement of the swivel joint parts relative to one another. As a result, the change of the adjustment angle can be carried out in a simple manner by handling the segments, without having to resort repeatedly.

In a possible detailed design, the first rotary joint part has a cylindrical recess with an inner side wall and a first end face, wherein the second rotary joint part has a cylindrical section rotatably received in the recess and a second end face, one of the two end faces having at least one axial directed projection, which is axially insertable for obstructing the rotary joint in a recess of the other end face. In this way, a slim design of the joints can be achieved. In addition, the arrangement of the projections and recesses in the end faces allows a wide variety of adjustable Angles. The angles can be equally spaced, for example in steps of 22.5 °, or also assume any discrete values.

In an expedient embodiment of the invention, a particular spring-loaded locking member is provided in the region of the articulated connection, wherein the locking member in a locked position of the rotary joint can be fixed, so that the axially directed displaceability of the rotary joint parts can be blocked by the locking member. Thus, the positive obstruction is additionally secured in a simple manner. In constructive detailing, this is preferably done by the locking member is spring-loaded on one of the pivot joints and snapped into a recess of the other hinge part. Components such as the hinge parts and the locking member are quite generally preferred as plastic parts, in particular injection molded parts made. Depending on the requirements, individual or all parts may also consist of metal or other suitable material.

In one possible development, the rotary joint parts are spring-loaded in the axial direction by means of a spring member. Preferably, the spring load takes place against the closing movement. In particular, can be dispensed with in such an embodiment, depending on the requirements for an axial locking of the hinge parts. In another preferred embodiment, the hinge parts are not spring loaded over their axial displacement. In particular, in such an embodiment, an above-mentioned locking member is preferably provided to ensure a backup of the articulated connection in the closed position. It is advantageous in such a solution without spring load that the segments can be pivoted without permanent axial application of force by the operator. Generally preferred, the blocking grid according to the invention thus has the simple and safe operating principle that a release of the positive fixing and setting the positive fixing by moving the segments in the direction of a rotation axis of the articulated connection between the attacks occurs.

In a particularly preferred embodiment of the invention, a passage part is additionally provided in the blocking grid which adjoins at least one of the segments. In a preferred, but not necessary, detailed design, the passage part comprises a fixedly positionable frame with a lower base and two side parts extending from the base, and a hinged to the frame about a pivot axis door member, wherein at one of the two, frame or door member , a closure member and on the other an abutment is arranged so that closure member and abutment cooperate in a closed position of the door member, wherein the door member for unlocking a positive blockage in the direction of the pivot axis is movable, wherein the mobility of the door member in the direction of the pivot axis is detachably lockable by means of an actuatable latch member. The door member is doubly secured in this way, since to open the latch member must first be actuated to subsequently allow a movement or lifting of the door member along the pivot axis. Only by this movement, the door member is released for opening or pivoting about the pivot axis. The blockage released by lifting can in principle be provided at the location of the closure member or integrated therewith or else separately therefrom or else both on the closure member and also separately therefrom. In a preferred detailed design of the passage part, the locking member is provided on the closure member, wherein the locking member in particular has a spring-loaded, linearly displaceable latch. This allows a simple integrated design of the double fuse. In particular, the closure member may be ergonomically shaped in the manner of a handle, so that a comfortable operation of the latch member and the lifting of the door are made possible for the adult with one hand.

Alternatively or additionally, a spring-loaded latch is provided on one of the two, closure member or abutment, wherein the latch snaps into a latch of the latch member upon pivoting of the door member in the closed position. As a result, the door member can automatically close when swiveling, in particular, the bolt of the latch member is separated from the case function. This allows, inter alia, a special strong design of a return spring of the bolt, which leads to an additional security against operation by the toddler. Depending on requirements, it may alternatively be provided that the spring-loaded latch itself has the function of a trap and snaps when swiveling the door into an abutment.

In a particularly preferred embodiment of the invention, an adjustable locking member is provided on the door member, wherein by means of the locking member one of the pivoting directions of the door member from the closed position out is lockable adjustable. This makes it possible to achieve an additional, selectable fuse of the door member. In a preferred detailed design, the locking member is provided on the closure member, so that there is a simple integrated structure. In the interest of a large range of functions by means of the locking member, preference is furthermore given to optionally no pivoting direction, one of the two Pivoting directions or both pivoting directions of the door member lockable, in particular, the locking member has two displaceable locking bolt. The locking member of an advantageous detail design may have a display for visual inspection of a set blocking function, so that an operator can already detect the set blocking function when approaching the passage member.

In a further advantageous embodiment of the invention, a further closure, in particular for the formation of the positive blockage, is arranged on the door member. In this way, in particular a higher load capacity of the door member can be achieved in the closed position. For example, the additional closure may be disposed at a lower portion of the door while the closure member and its abutment are disposed at an upper portion of the door for ease of operation such that obstruction of axial movement of the door member in one location and blockage against the other Pivoting the door in a lowered state takes place at another location. Alternatively or in addition, however, a positive blockade may also be provided on the closure member itself.

In a preferred detailed design of the further closure by the movement of the door member in the direction of the pivot axis is disengaged, so that here separate operation for the additional closure is required. An automatic and particularly reliable obstruction of the further closure during a pivoting of the door member can be achieved in that the further closure snaps when pivoting the door member in the closed position, preferably by means of a spring-loaded latch.

In a further preferred embodiment of the invention, it is provided that the pivot axis an inclination relative to a Vertical, wherein the pivot axis extends in particular in a plane with the frame and the closed door. As a result, it is achieved inexpensively and reliably that the door member pivoted into an open position pivots back into its closed position by means of gravity. In order to obtain sufficient restoring force on the one hand and harmless restoring force on the other hand, the inclination angle is between 1 ° and 5 °, preferably between 2 ° and 4 °. Due to the inclination of the pivot axis, a gravitational restoring force is generated when the door member swings open, since the emigrating center of gravity of the door member generates an increasing torque with respect to the inclined pivot axis. As a result, the door member pivots back into the closed position, even if the closing was forgotten by an adult or this just has no hand for free.

In another particularly preferred embodiment of the invention, in the interest of ease of use by an adult, it is contemplated to provide a protective door in at least one of the segments of the barrier, the protective door comprising a fixedly positionable frame having a lower base and two extending upwardly from the base extending side parts, a hinged to the frame door member which is pivotable about a pivot axis, and a closure, by which the door member and the frame are releasably secured to each other, comprising, wherein the closure comprises an actuator for at least partially releasing the closure, wherein the Actuator is fixedly arranged on one of the side parts of the frame. The arrangement of the actuator on the fixedly positioned frame allows easy operation of a stationary actuator, wherein the actuator is not held in a pivoting of the door in the hand, as in the case of arranged on the door member actuators. This allows a better support during the shutter opening and moves already intuitive a supplementary belching of the door member z. B. with the foot or leg. In this way, the operation for operators loaded with objects is particularly simplified.

Such a protective door is particularly well adapted to the operation of a barrier grid according to the invention by construction and type of operation. Among other things, this manifests itself in the fact that both an adjustment of segments of the blocking grid and an opening and closing of the protective door are carried out by very similar operating sequences, whereby the intuition of the operator is optimally supported. The protective door, apart from these particular effects in combination with a barrier grille, also constitutes an independent invention, for example in a version fixed in a building door frame. In this sense, the protective door with the features of claim 23 without combination with a barrier is an independent invention.

In a preferred embodiment of the protective door is provided between the door member and the frame a positive blockage against pivoting of the door member, wherein the blockage by movement of the door member to a defined stroke parallel to the pivot axis is releasable. The door member is doubly secured in this way, since to open the actuator must first be actuated to subsequently allow a movement or lifting of the door member along the pivot axis. Only by this movement, the door member is released for opening or pivoting about the pivot axis. The blockage released by lifting can in principle be provided at the location of the closure member or integrated therewith or else separately therefrom or else both on the closure member and also separately therefrom. Generally advantageous, the door member from the closed position in two directions can be swung open, which allows a particularly flexible use.

In a preferred embodiment of the invention, in the interest of ease of operation and construction, the actuator includes a spring loaded slider for opening the closure. Advantageously, the slider can be moved parallel to a plane spanned by the frame plane.

For easy provision of an improved fuse, it is provided that an abutment disposed on the door member can be covered by a movable bolt of the actuator, wherein a lifting of the door member is blocked by the overlap of the abutment. In a preferred embodiment, the counter-bearing can be designed in a simple manner as a horizontally projecting, in particular plate-shaped tongue. Further advantageously, a spring-loaded, preferably vertically movable, latch member may also be arranged on one of the two actuator or abutment, wherein on the other one with the latch member cooperating bracket member is arranged. When the door is thrown, the trap can then snap into the stirrup member. The latched latch member can advantageously also form a positive blockage, which can be solved by lifting the door, for example after a release by pulling back the actuator.

In a preferred embodiment, it is also provided that a second closure between the door member and the frame is provided. In a preferred embodiment, the second closure is arranged in particular on the lower base, whereby a good rigidity of the closed door is given in the lower area. Of the second closure is solvable in a preferred detail by movement of the door member to a defined stroke parallel to the pivot axis. This type of blockage which can be released by lifting the door can be designed either exclusively or in addition (as a second positive-locking block) by the second closure.

In the interest of a simple and secure closure operation, it is provided that the second closure snaps into the closed position during pivoting of the door member, in particular by means of a spring-loaded latch.

In one possible embodiment of the invention, the frame between fixed structures, for example, door frames, walls or stair railings, is demountable fixed. The determination can be done by jamming or screwing or otherwise.

Generally advantageous, the door member may be acted upon with a restoring force, for example by means of spring action in a restoring hinge.

Further advantages and features of the invention will become apparent from the embodiment described below and from the dependent claims.

A blocking grid according to the invention can have two or more planar segments 101, between each of which an articulated connection 102 is provided. In Fig. 1, a barrier grid with six segments 101 is provided, which are arranged in a closed hexagon in the manner of a playpen for a toddler.

An articulated connection 102 of two segments 101 each has a first axis of rotation D1 and a second axis of rotation D2 spaced therefrom by a distance d. This is structurally realized in that on each of the adjacent segments 101 each end an upper and a lower pivot 103 are provided, so that ever two of the pivots 103 are each associated with one of the axes of rotation D1, D2.

Each of the four hinges 103 of the articulated connection 102 has a first hinge part 104 and a second hinge part 105, which are each formed as molded parts, in particular injection-molded parts made of plastic.

The first hinge part 104 is rigidly connected to the segment 101 by an upper or lower crossbar 106 of the segment 101 is inserted into a pocket 104 a of the hinge part 104 and glued and / or screwed there.

The second hinge part 105 is rotatably received with respect to the segment 101 in the first hinge part 104, wherein a cylindrical outer side wall 105 b of the second hinge part is guided on an inner cylindrical side wall 104 b of the first hinge part.

A strut 107 is received and fixed with each of its ends in each case an axially directed pocket 105a of the second pivot portions 105 of a segment 101, for example by means of adhesive and / or screws.

The strut 107 forms with the end-side second hinge parts a rigid unit which is rotatable in the first hinge parts 104 and relative to the segment 101.

The mutually parallel struts 107 and rigid units of adjacent segments 101 are interconnected by means of connectors 108 (see FIG. 3). Depending on a connector 108 is with pairs of Spring tongues 108a, which extend on both sides symmetrically from a central contact piece 108b of the connector, inserted in the manner of clips in a receptacle 105c and positively releasably latched. The rectangular-section aperture 105c is formed at a neck portion of each of the second hinge portions 105 between the strut pocket 105a and the cylindrical wall portion 105b guided in the first hinge portion 104.

The connectors 108 have a central plane of symmetry and may be inserted into the pivot joint parts 105 in any two orientations, with the abutment piece 108b having two concave surfaces for abutment with the second hinge parts 105, 105 '. As a result, the hinges and axes of rotation D1, D2 of the adjacent segments are held at the same time at a defined distance d.

Fig. 4 shows an end connector 118, by means of which a terminal segment of the barrier grid can be releasably secured to a wall or similar structure. The end connector 118 has a main body 118a with holes 118b for screwing or otherwise securing e.g. on a wall or on a door frame. From the main body 118a extends a pair of spring tongues 118c which are identical to the spring tongues of the connector 108 and can engage in the receptacles 105c, 105c 'of the second rotary joint parts 105, 105'.

The rotational mobility of the second hinge part 105 in the first hinge part 104 is releasably lockable in discrete, defined angular positions, as illustrated by the following detailed description of the hinge parts 104, 105. The first hinge part 104 has a cylindrical recess with the inside cylindrical side wall 104b, wherein the recess in the axial direction of a perpendicular to the rotation axis D1, D2 extending, forming an end face of the recess bottom 104c is limited. The bottom 104c has a central bore 109 for the passage of a retaining screw 110 and a projection 105d of the first hinge part 105th

The protrusion 105d protrudes centrally from an end face 105e of the second swivel joint part 105, which runs parallel to the bottom 104c of the first swivel joint part 104b, perpendicular to the rotation axis D1, D2.

By means of the screw 110, a stopper plate 111 is fixed to the projection 105d during assembly of the rotary joint, whereby the bottom 104c is enclosed between the stopper plate 111 and the end surface 105e of the second hinge part 105.

The assembled unit of second hinge part 105 and stop plate 111 is slidable axially relative to the first hinge part 104 by a stroke a (see FIG. 8), with the stop plate 111 moving in a hollow cylindrical space 104f above the bottom 104c. The hollow cylindrical space 104f is closed by a latched decorative cap 112, which is not essential for the function of the rotary joint.

In order to allow obstruction of the swivel joint in discrete angular positions, concentric recesses 113 in the form of circular openings are provided in the bottom 104c of the first swivel joint part. With these recesses correspond axially directed projections 114 of the second Fulcrum part 105. The projections 114 are concentrically arranged on the end face 114f of the second hinge part.

In the present example, the recesses 113 are cylindrical bores and the protrusions 114 are cylindrical pins. There are as many projections 114 as holes 113, namely 16, are present, wherein they are arranged at the same angular distance of 22.5 ° to each other. This ensures that the swivel joint in

Angular distances of 22.5 ° can be locked, wherein by the plurality of intermeshing or positively engaging pins and

Recesses a particularly safe and torque-resistant

Obstruction is achieved.

The obstruction or release of the two rotary joint parts 104, 105 takes place by means of an axial displacement of the second rotary joint part 105 or the unit of rotary joint parts 105, 105 'and strut 107 relative to the second rotary joint parts 104.

FIG. 8 illustrates this by comparing the blocked position (right figure) and the released position (left figure) in the case of an upper pivot 104, 105.

Overall, this thus achieved that a release of the positive fixing and setting the positive fixing of adjacent segments by displacement of the segments in the direction of a rotational axis D1, D2 of the articulated connection 102 between respective attacks occurs. A stop in the opening direction is formed by the stopper plate 111 and the bottom of the space 104f. A stop in the closing direction is formed by the bottom 104c and the end face 105e, as the comparison of Fig. 8 shows. In order to secure the axial displacement at least in the locked position or to block releasably, a locking member 115 is provided on the hinge parts. The locking member 115 includes a guided in the first hinge part 104 in a groove 104g and with a spring 116 linear kraftbeaufschlagten latch 117, the leading edge can snap into an annular groove 105f of the second hinge part 105. In the snapped-in position (see FIG. 8, left), no axial displacement of the rotary joint parts 104, 105 is possible. In order to solve the obstruction, therefore, first the bolt 117 must be moved against the spring force, after which the operator moves the hinge parts 104, 105 against each other to then change the pivot angle of the segments 101 and finally the pivot joints under snapping the locking member 115 back into the locked position (see Fig. 8 left) pushes.

In the following reference is made to constructive differences between the upper pivot joints and the lower pivot joints. The lower hinges are not equipped with a locking member 115 so as not to complicate the operation unnecessarily. In this case, only the latch 117 is not provided, wherein the first hinge part 104 together with the receiving groove 104g is identical for the upper and lower swivel joints.

Fig. 6a shows a slightly modified second hinge part 105 'intended for use in the lower pivot joints. It differs from the second hinge part 105 (see FIG. 6) in that the axial projections 114 are not provided on the end face 105e but on an end face of the stop plate 111 'facing the bottom 104c. As a result, both rotary joints of a rotation axis D1, D2 can be blocked or released at the same time. In this design of the second hinge part 105 'is a second end face according to the invention on the stop plate 111' is provided, whereas in the upper second rotary joint part 105, the second end face according to the invention, the end face 105e of the cylindrical portion 105b.

It is understood that as an alternative to the described examples, the projections on the bottom 104c and the corresponding recesses on the second hinge part 105, either on the end face 105e or on the stop plate 115, may be provided.

It is within the scope of the invention also conceivable that only one of the two hinges of a rotation axis is lockable formed, for example in the manner of an upper hinge 104, 105 or in the manner of a lower hinge 104, 105 '.

In a further alternative, not shown embodiment, the two hinge parts 104, 105, 105 'in the axial direction spring-loaded to each other. For this purpose, for example, in the case of the lower swivel joint 104, 105 ", a spiral spring could be provided in the hollow cylindrical space 104f biased under pressure, so that the swivel joint is pressed into the closed position by the spring ,

The sheet-like segments 101 can, as shown for example in FIG. 2, be formed as a grid with upper and lower transverse struts 106 and intervening bars 119. Alternatively, the segments of the barrier may also comprise closed surfaces of wood or plastic, in particular of transparent plastic. One or more of the flat segments 101 may also be formed as a passage part, see for example FIG. 1 at the front or FIG. 9. In this case, a door member 6 is provided in the planar segment, which is arranged between side parts 3 ', 4' and can be opened separately. On the side parts 3 ', 4' are each hinges 103 as described above arranged to connect the passage part to another segment 101 of a barrier grid according to the invention hinged.

Another detailed embodiment of a passage part with a door member is shown in FIGS. 10 to 18.

The passage part shown in Fig. 10 to Fig. 18 is formed in the manner of a door protection grid for fixing in a door frame. In contrast to the passage part of a barrier grille according to the invention (FIG. 9), the side parts 3, 4 are not equipped with the above-described hinges for connection to further segments of the barrier grille, but with clamping screws 5 for mounting in a door frame. Hereinafter, details and function of the passage part will be described with reference to FIGS. 10 to 18, wherein, according to the present invention, the passage part is used as a segment 101 of a blocking grid (see FIGS. 1, 9), by attaching to the side parts 3, 4 the pivot joints 103 described above are arranged as shown in FIG. 9 (not shown for the passage part of FIG. 10).

The passage part according to FIG. 10 comprises a frame 1, which essentially consists of a lower base 2, a first, vertical side part 3 and a second, vertical side part 4. The frame 1 is by means of two each arranged on each of the side parts 3, 4 clamping screws 5 in, for example, a door frame positionable. The clamping screws can engage in a known manner in screwed to the door frame base (not shown). The clamping screws 5 arranged on the side part 4 are provided with an optional extension 5a for fixing in over-wide door frames, a vertical stabilizing rod 5b being provided between the extensions 5a. By replacing the provided with clamping screws 5 side parts 3, 4 by side parts 3 ', 4' with hinges (see Fig. 9) results in a passage portion as a segment 101 of a barrier grid according to the invention.

In the frame 1, a door member 6 is pivotally received. This is done by means of an upper pivot bearing 7 and a lower pivot bearing 8. The upper pivot bearing 7 is formed as a plastic casting and fixed on the one hand to an upper end of the second side part 4 and on the other hand to an upper crossbar of the door member 6. The lower pivot bearing 8 comprises a pin 8 a, which is received in the base 2 of the frame 1 and projects into a bore in a lower transverse strut of the door member 6.

A pivot axis S of the door member 6, which is defined as a connecting line of the two pivot bearings 7, 8, -bei vertical positioning of the frame 1 has an inclination at an angle α, wherein the pivot axis in the plane of the frame 1 and the closed door member 6 extends , The angle α in the present example is about 3 ° (see also Fig. 17, where the section line A-A is perpendicular).

By this inclination by the angle α of the center of gravity of the door member moves in a swiveling upwards, so that an increasing moment is generated in the respective closing direction. In Fig. 10, the inclination of the slightly open door is recognizable. In addition, it is noted that Fig. 11, the passage part in a respect to the Clamping screws 5 not yet adjusted state shows what is the reason for the gap between side part 3 and door member 6 there.

The upper pivot bearing 7, see detail in Fig. 17, has a door-side hinge half 7a with a first hinge half 7b and a frame-side hinge half 7c with a second hinge half 7d. The joint halves 7b, 7d are inserted into one another, the joint halves being displaceable relative to one another by a stroke H in the direction of the pivot axis S (joint axis). The one hinge half 7d has on a cylindrical wall 7e two radially projecting and axially continuously extending cams 7f, which are supported as a support against a corresponding wall of the other hinge half 7b. The two cams 7f are arranged in the plane of the closed door member. Overall, the friction surface is reduced and tilting in the course of an axial displacement of the joint halves 7b, 7d each other avoided. The joint halves 7a, 7c are each arranged inclined at the angle α, while the upper sides of areas to be fixed to the door member 6 and side part 4 of the pivot bearing 7 extend horizontally, which can be seen in particular in FIG.

The lower pivot bearing 8 is formed so that the lower transverse strut 6a of the door member 6 projects into a recess 4a of the pivot-side side part 4. In this way, a maximum stroke H of the door member is defined during a movement in the direction of the pivot axis S, wherein the transverse strut 6a abuts at the end of the stroke H at an upper edge of the recess 4a.

For releasable fixing of the door member 6 to the frame 1 in a closed or pivoted position, a closure member 9 and an abutment 10 are provided. The closure member 9 is presently arranged at one end of an upper crossbar 6b of the door member 6 and the anvil 10 is disposed on the opposite side part 3.

The closure member 9 is largely formed as a plastic casting and comprises an upper housing part 9a, a lower housing part 9b, a linearly displaceable latch 11 with an operating knob 11a and an end opening 11b, a latch 11 loading spring 12 and two locking bolt 13, 14 (see in particular FIGS. 12 to 15), the function of which will be described below. The mutually mounted housing halves 9a, 9b are connected to the end of the upper cross member clamped and / or positively. Between the housing parts of the bolt 11 and the locking bolt 13, 14 are slidably received added.

In particular, from Fig. 14 it can be seen that the latch 11 is located in the upper housing part 9a, wherein in the lower housing part 9b below the bolt 11, an opening portion 9c is provided, the side flanks jump back 9d.

The anvil 10 (see FIG. 16) comprises a housing part 10 a, which is pushed onto the upper, door-side corner of the first side part 3 and screwed. In the housing part a particular metallic pin 10b is received linearly displaceable, which is loaded by a spring 10c. The pin 10a forms a spring-loaded case, which engages in the closed state of the door member in the opening 11b of the bolt 11 of the closure member 9.

The function of the closure member is now as follows:

When closed, the case 10a projects into the opening of the 11 b of the bolt 11, so that the door member against both lifting as a pivoting about the pivot axis S is blocked. By pressing the control knob 11a, the bolt 11 can now be pushed back against the spring, so that a lifting of the door member is made possible by the described stroke H in the direction of the pivot axis. In this case, a pivoting is initially blocked by the end flanks 9e of the upper housing 9a, so that a pivoting blockade is given by the closure member even after releasing the locking member formed by bolt 11 and 10b latch member.

After lifting the door member about the free stroke H defined by hinge 8, the pin or latch 10a is level with the recessed lateral flanks 9d of the lower half of the housing, thereby pivoting the door member with respect to the latch 10. In principle, the door can now be swung open in both directions.

In the present embodiment, a locking member integrated in the closure member is also provided that the two locking bars 13, 14 comprises. The locking bars each have a below through openings from the housing part 9b projecting operating pin 13a, 14a, by means of which each of the locking bolt 13, 14 is independently displaceable over in a blocking, front position or a releasing, rear position. In these positions, the control pins 13a, 14a engage in respective detents 16, which are formed in the openings of the lower housing half 9b. In the blocking position, a front tongue 13b, 14b of the locking bolt projects in each case in front of the flanks 9c of the lower housing half 9b, so that the latch 10b of each of the locking bolts can be locked in each case in a pivoting direction of the door member. By the displacement of one or both locking bolt 13, 14 so an opening of the door is either in one of the two directions or in both directions completely lockable. In this way, an additional security against operation by a toddler can be achieved and the opening function of the door member can be adapted to the respective installation situation of the protective grid or passage part. This may be desired, for example, when positioning on a landing, in which the pivoting in a certain direction should be prevented in principle.

The adjustment of the locking member 13, 14 is easily and clearly recognizable by an additional display, each comprising a viewing window 9f for each of the locking latch, wherein the viewing window 9f is formed as an opening in the top of the upper housing half 9a. Furthermore, the locking bars 13, 14 each have a covering with the windows 9f indicator surface 13c, 14c, which has, for example, a color marking. Depending on the exact configuration, it may be provided, for example, that when the locking bar 13, 14 is in its associated viewing window 9f, a red marking is visible and, when the locking bolt 13, 14 is pushed back or opened, a green marking.

Upon a pivoting of the open door member, which can take place in particular automatically, in this case by gravity, slides the case 10b on the curved outer surface of the flanks 9e of the upper housing part 9a along and is thereby pressed against the spring action. As soon as the latch 10b comes into register with the opening 11b of the latch 11, it snaps into it and the door is locked. It is understood that the latch 11 is basically in its closed position due to the spring 12, as long as not an operator on the control knob 11 a in the opening direction of the bolt 11 exerts.

In addition to the closure member 9 described above, the passage member also has a further closure 15, which is arranged at a distance from the closure member 9 on an underside of the door member 6.

Fig. 18 shows this closure in the closed state. An upper one

Shutter half 15a is screwed to the lower transverse strut 6a of the door member 6 and comprises a vertically projecting lower locking pin 15b, which is movable in the manner of a latch in its longitudinal direction movable and subjected to a downward force by means of a spring, not shown.

The closure pin 15b protrudes in the closed door state into a recess 15e of an abutment 15c screwed to the base 2 of the frame 1. The side walls 15d of the anvil are chamfered outwards, so that the spring-loaded latch 15b slips over the oblique side walls when the door is swiveled and is then compressed, after which it snaps into the recess 15e.

To open the door member 6 of the other closure 15 is brought by lifting the door member 6 by the aforementioned stroke H disengaged.

In the present embodiment, the closure member 9 additionally and spaced arranged closure 15 is an flanking and the closed door stabilizing measure, the basic closing function is already integrated in the closure member 9. In other embodiments of the invention, the closure 15 can also be omitted or the blockade of the Door member against pivoting can be provided exclusively by the further closure.

The passage part shown in FIG. 9 has several differences from the passage part of FIGS. 10 to 18 described above in detail.

The counter-bearing 10 'is not formed in the variant of FIG. 9 as mounted on a frame corner plastic molding. Rather, the counter bearing is in a closure member 9 opposite recess in the wooden side part 3 'used. In this case, just as in the example according to FIGS. 10 to 18, a spring-mounted latch 10 b projects into the front-side opening 11 b of the closure member 9.

Furthermore, the pivot axis S 'of the passage part of FIG. 9 is not inclined, but perpendicular, so that in the example of FIG. 9, no gravitational restoring force acts on the open door member 6.

Furthermore, the upper pivot bearing T of the door member 6 of FIG. 9 is substantially formed as a simple, 90 ° angled metal pin, which is screwed with its horizontal end in the side part 4 'and with its vertical end in a bore in the upper cross member

6b of the door member protrudes. In this hole is the metal pin around the

Hub H slidably received to allow the opening and closing of the door member, otherwise exactly as in the example of FIG.

10 to Fig. 18 works.

In general, it should be noted that the term "passage part" in the

According to the invention, not only door members with lattice-like structures comprises, as in the present embodiment, the door member with its transverse struts 6a, 6b and longitudinal struts, but also closed surfaces, for example of wood or plastic, in particular a transparent plastic such as polycarbonate or Plexiglas.

It is understood that the individual features of the various embodiments of the invention, in particular the two variants of a passage part according to FIG. 9 and FIG. 10, can be combined with one another as required.

FIGS. 19 to 26 show a further example of a releasably lockable passage part of the blocking grid. This passage part may be provided on one or more segments of the barrier grille as an alternative or in addition to the passage part described above and shown in FIGS. 10 to 18. The passage part according to the further example is hereinafter referred to as "guard door".

The protective door shown in FIG. 19 comprises a frame 201 which essentially consists of a lower base 202, a first, vertical side part 203 and a second, vertical side part 204. The protective door is designed as a segment of an erectable playpen or barrier grid, for which purpose articulated connections 102 for the adjustable connection of further segments are provided on the side parts 203, 204.

The frame 201 can be positioned in an alternative, not shown embodiment by means of arranged on each of the side parts 203, 204 clamping screws in, for example, a door frame. The clamping screws can engage in a known manner in screwed to the door frame base (not shown). The clamping screws can also be equipped in a known manner with an optional extension for fixing in over-wide door frame. In the frame 201, a door member 206 is pivotally received. This is done by means of an upper pivot bearing 207 and a lower pivot bearing 208. The upper pivot bearing 207 is formed as a plastic casting and fixed on the one hand to an upper end of the second side part 204 and on the other hand to an upper crossbar of the door member 206. The lower pivot bearing 208 includes a hinge pin 208a that is received in the base 202 of the frame 201 and protrudes into a bore in a lower transverse strut of the door member 206.

A pivot axis S of the door member 206 is defined as a connecting line of the two pivot bearings 207, 208.

The upper pivot bearing 207, see detail in Fig. 23, has a door-side first hinge half 207a, which on an upper cross member

206b of the door member 206 is fixed, and a frame-side second

Joint half 207b. The hinge halves 207a, 207b are over a

Hinge pin 207c connected to each other, wherein the hinge halves 207a,

207b are displaceable by a stroke H in the direction of the pivot axis S (hinge axis) to each other.

The joint 207 is designed as a self-closing joint, for which purpose the joint halves cooperate along inclined running surfaces 207d. When pivoting the door from the closed or middle position, the hinge halves 207a, 207b press on their running surfaces 207d from each other, so that the door member 206 undergoes a stroke upward. Correspondingly, a restoring force directed downwards along the pivot axis effects a resultant torque for returning the door member to the closed position. The restoring force is generated by the weight of the door member as well as by a return spring 208b, which in the present case is located on the hinge pin 208a of the lower pivot bearing or is supported between door member 206 and hinge pin 208a. Fig. 25 shows the lower pivot 208 in a position in which the door member 206 is lifted by the stroke H and the spring 208a is fully tensioned.

For detachable fixing of the door member 206 to the frame 201 in a closed or pivoted position, a closure 205 is provided. The closure 205 is arranged in the upper region of the protective door on the first side part 203 and the adjacent end of the upper transverse strut 206b opposite the pivot 207.

The closure 205 comprises an actuator 209, which is arranged at the upper end of the first side part 203 and thus fixed to the frame and not on the pivotable door member 206. The

Actuator 209 has one with the present wooden side part

203 bolted bearing block 211, on which a slider 210 by means of a

Guide groove 210c is slidably mounted. The slider 210 is force-urged in the closing direction by means of a spring 210b supported against the side part 203 and can be operated by operation e.g. be moved with the thumb against the spring force. The slider 210 is in the

Representation of Fig. 21 in the horizontal from right to left movable (see arrow P in Fig. 20), ie parallel to the plane which is spanned by the frame 201.

The slider 210 includes a latch 210 a, which is formed as a protruding projection in the direction of the door member materially integral with the slider 210. The latch 210a covers in the closed state (FIG. 19) an abutment 212 which is arranged on the door member 206. The counter bearing 212 is formed as a plastic injection-molded part and screwed and / or glued to the outer end of the wooden upper cross member 206b of the door member 206. The abutment 212 has a projecting tongue 213 provided with a bore 214. The tongue 213 also has two lateral bevels 215.

Furthermore, a spring-loaded latch 216 is provided on the bearing 211 and the side part 203, which includes a vertically movable pin 217 and a spring 218 supported between pin 217 and side member 203. The pin 217 has a rounded tip that projects upwardly over a surface of the bearing 211 and is retractable against the force of the spring 218.

The function of the closure 205 is now as follows:

In the closed state (FIG. 19), the slider 210 is displaced in the direction of the side part 203 by an operator, so that the latch 210a no longer covers the tongue 213. In this state, the pin 217 of the latch 216 still engages through the bore 214 of the tongue 213, so that a pivoting of the door member is still blocked. The engagement of the latch 216 in the bore (bracket member) 214 thus continues to cause a positive blockage against pivoting of the door member 206th

In a second step of the opening process, the door member 206 is then lifted by the stroke H, whereby the tongue 213 of the abutment 212 is lifted above the pin 217 or the positive blockade is released and the door can be swung open. The swinging of the door member can be done either in both directions, as it is in completely unlocked and raised state can swing freely through the frame 201.

During the closing operation, slide 210 and door member 206 are in the basic position due to the restoring forces. The door can be swung in by hand or simply released, so that it is swung by the resetting hinge 207. At the

Turning first accesses a respective of the bevels 215 of

Tongue 213 at the rounded tip of the pin 217 so that it is pressed down. When covered with the bore 214 of the pin 217 then snaps into the bore 214, so that the bore

214 forms a bracket member for the case 216.

In addition to the closure 205 described above, the protective door has a further closure 219, which is arranged at a distance from the closure 205 on an underside of the door member 206. Fig. 24 shows this

Closure 219 in the closed state. An upper half closure

219a is screwed to the lower transverse strut 206a of the door member 206 and comprises a locking pin 219b projecting vertically downwards, which is movable in the manner of a latch in its longitudinal direction and is subjected to downward force by means of a spring, not shown.

The closure pin 219b protrudes in the closed door state into a recess 219e of an abutment 219c screwed to the base 202 of the frame 201. The side walls 219d of the

Anvil are bevelled outwards, so that the spring-loaded

Trap 219b when the door is tilted over the oblique

Sidewalls slips and is compressed, after which it snaps into the recess 219e. To open the door member 206, the further shutter 219 is disengaged by lifting the door member 206 by the aforementioned stroke H. The second closure 219 thus also forms a positive blockage against pivoting of the Tütglieds.

In the present exemplary embodiment, the second closure 219, which is additionally and spaced apart from the closure 205, constitutes a flanking measure which stabilizes the closed door, the basic closing function being already integrated in the closure 205.

In general, it is pointed out that the term "protective door" in the sense of the invention not only door elements with lattice-like structures, as in the present embodiment, the door member with its cross struts 206a, 206b and longitudinal struts has, but also closed surfaces, for example made of wood , Plastic or Plexiglas.
