Description

The invention relates to a child safety gate according to the preamble of claim 1.

Generic child safety gates, also referred to as door and stair gates, are known from the prior art.

In order to adapt the U-shaped frame, in which the pivoting door is pivotably mounted, to different passage widths, so-called extensions for door safety gates and stair gates are known. On May 16, 2017, an offer for such an extension for a stair gate "ayana" was available on the website of the company IB-Style at http://www.ib-style.de/kids/Sicherheitsgitter/495/ayanaverlaengerungen?c=103 . The extension part in widths of 7, 14 and 28 cm is inserted laterally into the second vertical bar on the hinge side to widen the door safety gate. A maximum of two extension parts can be fitted to adapt the U-shaped frame to the passage width. The extension part essentially consists of two spaced-apart horizontal bars which are connected to one another in the vertical direction by at least one lattice bar. The U-shaped frame, which has been extended in this way, is braced using clamping screws which are provided with clamping plates at the ends. The clamping screws are arranged on the one hand on the first vertical bar and on the other hand on the horizontal bars of the extension part.

The extension parts lead to a certain instability of the child safety gate braced in the doorway. Another disadvantage is that although the child safety gate is adapted to the width of the passage to be secured, the effective passage width still corresponds to the width of the pivoting door.

the DE 601 11 439 T2 discloses a safety barrier with such extension parts, consisting of two main elements, namely a standard barrier and an extension section on both sides thereof. The standard barrier comprises a rigid U-shaped frame with a horizontally extending beam and at the two ends thereof a vertically extending column. The pivoting door is pivotably mounted and lockable in the U-shaped frame. The extension sections increase the barred non-pivoting door area of the doorway when the safety barrier is adapted to accommodate wider doorways.

Furthermore, from the GB 2498523A a child safety gate is known, which does not have a U-shaped frame, but a first and a second spaced-apart wall mounting parts attached to the lateral boundaries of the passage. The first wall attachment part has the pivot bearing for the pivoting door, and the second wall attachment part has the locking mechanism for the pivoting door. Depending on the passage width, the width of the pivoting door can be adjusted to different distances between the first fixed wall attachment part and the second fixed wall attachment part. For this purpose, the pivoting door has a locking section and a pivoting section, with a variable number of spacer elements being arranged between the locking section and the pivoting section. The spacer elements each have an upper and lower horizontal door rail section and a vertical rail extending between the upper and lower door rail sections. The detachable connection between the individual components of the pivoting door takes place via plug-in connections between the individual components that latch with one another.

Starting from the DE 601 11 439 T2 As the closest prior art, the object of the invention is to create a child safety gate that can be adapted to different passage widths, in which instabilities are avoided and at the same time the effective passage width is increased.

• - die Schwenktür in der Breite auf unterschiedliche Abstände zwischen dem ersten und zweiten vertikalen Holm des U-förmigen Rahmens einstellbar ist und
• - zur Einstellung der Breite der Schwenktür mindestens ein den Abstand zwischen dem Verriegelungsabschnitt und dem Schwenkabschnitt vergrößerndes Zwischenstück lösbar mit dem Verriegelungsabschnitt und dem Schwenkabschnitt verbindbar ist.

This object is achieved with a child safety gate according to the preamble of claim 1 in that

• - the pivoting door is adjustable in width to different distances between the first and second vertical bars of the U-shaped frame and
• - To adjust the width of the pivoting door, at least one intermediate piece, which increases the distance between the locking section and the pivoting section, can be releasably connected to the locking section and the pivoting section.

According to the invention, the adaptation to different passage widths does not take place by filling the resulting intermediate space between the U-shaped frame and the lateral borders of the door passage, but rather by adapting the width of the U-shaped frame by means of spacer sleeves. The clamping forces are introduced into the vertical bars of the U-shaped frame via the clamping screws and run through each spacer sleeve guided by the connecting profile. Forces therefore primarily act on each spacer sleeve in the longitudinal direction of the cross brace, so that the U-shaped frame is guided by the spacers does not lose any stability. The bending moments acting in the cross brace are transmitted by the connecting profile. Stability is further improved if each spacer sleeve can be pushed onto the connecting piece without play. In addition, the freedom from play ensures that the end faces of the spacer sleeve(s) are in precise contact with the first and second parts of the cross brace.

Depending on the longitudinal extent of the spacer sleeves in the direction of the cross brace, the width of the pivoting door can be easily adjusted to different distances between the first and second vertical beam of the U-shaped frame, in that the pivoting door has a locking section and a pivoting section, the pivoting section in the u- shaped frame is pivotably mounted, the locking section can be locked with the first vertical beam when the swinging door is in a closed position, and at least one intermediate piece, which increases the distance between the locking section and the swinging section, can be releasably connected to the locking section and the swinging section in order to adjust the width of the swinging door.

The width of each intermediate piece preferably corresponds to the width of each spacer sleeve. In any case, the total width of all intermediate pieces must correspond to the total width of all spacer sleeves.

The terms "vertical" and "horizontal" used in the description and claims refer to a child safety gate properly fixed in one passage; they are used for simplified identification of the components of the child safety gate, but not to define an arrangement of the components in an exactly vertical direction or horizontal direction to the ground surface.

The first and second parts of the cross strut and each spacer sleeve are designed to be advantageous in terms of construction as hollow profiles with a matching cross section, in particular a rectangular cross section. The two parts of the cross brace and each spacer sleeve are aligned with one another in such a way that the lateral surfaces of the hollow profiles are aligned with one another. The spacer sleeves inserted into the cross brace are practically invisible. In particular, no interfering edges are created in the passage through the child safety gate due to the width adjustment. Finally, the abutting, congruent end faces of the two parts of the cross brace and each spacer sleeve bring about an optimal flow of forces within the cross member.

The connecting profile is preferably attached to the inner wall of one of the two parts of the cross strut designed as a hollow profile. This prevents displacement of the connecting profile, for example within the first part of the cross brace. That part of the connecting profile which extends beyond the end opening of the first part of the cross brace has a length which is greater than the total length of the maximum spacer sleeves to be accommodated. The section that protrudes beyond the spacer sleeves to be accommodated extends into the second part of the cross brace, which is designed as a hollow profile. The cavity of the second cross brace also forms the receptacle for the plug connection.

• - Each intermediate piece comprises an upper and a lower horizontal door pillar section and at least one lattice bar extending in the vertical direction between the horizontal door pillar sections.

The detachable connection of each intermediate piece is preferably established starting from the easily accessible locking section of the pivoting door designed as a lattice construction.

A particularly advantageous detachable connection of the intermediate piece in such a child safety gate is characterized in that

• - the detachable connection has a first and a second threaded rod, a first and a second transverse nut bolt, each with a bolt axis and a threaded hole, and a first and second sleeve nut, each with an internal thread and a screw head,

• - the first threaded rod passes through a bore in the locking section, the upper horizontal door pillar section of each intermediate piece and the upper horizontal door pillar section of the pivoting part (5e) up to the threaded hole in the first cross nut bolt,
• - the internal thread of the first sleeve nut is screwed onto the end of the first threaded rod opposite the first transverse nut bolt, the screw head of which bears against an end face of the locking section,

In order to improve the alignment of the door pillar sections of the locking section, the pivoting section and the intermediate pieces when connecting the parts to form the pivoting door, centering and connecting frames can be arranged between the end faces of adjacent door pillar sections.

In an advantageous embodiment of the invention, the threaded rod for the detachable connection of the components of the pivoting door can consist of several parts which are connected to one another via threaded sleeves. The length of the parts of the threaded rods is adapted to the longitudinal extension of the intermediate pieces. Depending on the number of spacers required, the length of the threaded rod can be adjusted. If you are working with one-piece threaded rods, these must be available in different lengths for width adjustment.

In the prior art, the lock of the locking mechanism of a child safety gate usually has an unlocking mechanism which is arranged at the level of the upper edge of the pivoting door. The unlocking mechanism can already be reached by small children aged up to 24 months. Measures are therefore required to prevent accidental unlocking of the lock by the small child. Specifically, EN 1930:2012-02, for example, requires that unlocking requires at least two consecutive steps, with the execution of the second step being dependent on the execution and maintenance of the first step, or that unlocking the opening system requires at least two separate but simultaneous steps requires that work on different principles.

In an advantageous embodiment of the invention according to claim 8, the child safety gate is provided with an unlocking mechanism which is arranged completely inaccessible to the small child, on the one hand because the actuating member is positioned at a height that the small child cannot reach and on the other hand because the force-transmitting parts the unlocking mechanism are guided from the actuator to the at least one lock in a hollow body. Preferably, upper and lower locks are disposed between the pivoting door and the U-shaped frame, locking the pivoting door to the frame in a closed position.

The unlocking mechanism has a rod-shaped actuating member, at one end of which the actuating member is arranged at the end. The rod-shaped actuator is guided inaccessible in the vertical hollow profile, which protrudes so far beyond the upper edge of the pivoting door that the actuator arranged outside of the hollow profile is above an access height for children aged up to 24 months. Each lock preferably has a lock latch that can be engaged and disengaged in a recess. Each lock latch is connected, for example via a flat cam gear, to the single rod-shaped actuating element which is guided in the hollow profile in a longitudinally displaceable manner in the vertical direction.

The invention is explained in more detail below with reference to the figures. Show it

• 1 a perspective exploded view of a child safety gate according to the invention and
• 2 an enlarged view of a cross brace of a U-shaped frame of the child safety gate 1 .

The child safety gate comprises a U-shaped frame with a first vertical bar (1) and a second vertical bar (2) arranged at a parallel distance therefrom, the two vertical bars (1,2) being connected to one another on the bottom by a cross brace (3). .

The U-shaped frame is braced, for example, in a doorway that is not shown in the drawing. The clamping is carried out with the help of clamping screws (4), which are provided with clamping plates (4a) at the end. A bearing section (2a) is attached to the upper end face of the second vertical beam (2). In the U-shaped frame between the bearing section (2d) and a bodensei Term bearing in the cross brace (3) a pivoting door (5) in two passage directions (5a, b) pivotally mounted. An upper and a lower lock (6) of the same design lock the pivoting door (5) in the in 1 illustrated closed position in the frame.

The vertical beam (1) is designed as a two-part hollow profile, with a first part extending up to the height of the upper edge (5c) of the swing door and a second part extending from the upper edge (5c) to an outlet opening on the upper end face of the hollow profile . The second part of the hollow profile protrudes so far beyond the upper edge (5c) of the pivoting door (5) that an actuating element (7) arranged outside the hollow profile of an unlocking mechanism for the locks (6) above an access height for children aged up to 24 months, i.e. at a height of about 1.20 m. The actuating element (7) is firmly connected to a rod-shaped actuating element guided within the hollow profile for opening the upper and lower lock (6).

Each lock (6) comprises a lock latch (6b) which can be engaged and disengaged in a recess (6a) and which engages in the recess (6a) when the pivoting door (5) is in the closed position. The actuating element, which is guided inside the vertical beam (1) designed as a hollow profile, is connected via a cam mechanism to the lock latch of both the upper and lower lock in order to convert a downward, translatory movement of the actuating member within the hollow profile into a horizontal, translatory disengagement movement to implement the lock latch.

In order to increase the width of the frame of the child safety gate, the crossbar (3) has a first part (3a) and a second part (3b) which are detachably connected to one another by means of a plug connection (8). The plug connection (8) has a connecting profile (8a) which is arranged on the first part (3a) and which engages in a receptacle (8b) in the second part (3b) of the cross brace (3). To increase the length of the cross brace (3), two spacer sleeves (3c) are pushed onto the connecting profile (8a) in the illustrated embodiment. The spacer sleeves (3c) have a matching longitudinal extension. After the plug-in connection has been made, the pushed-on spacers (3c) lie on a first end (3d) on the left in the picture on the second part (3b) and on an opposite end (3e) on the right in the picture on the first part (3a) of the cross brace (3) (cf. 2 ).

How to proceed in particular 2 As can be seen, the first and second parts (3a,b) of the cross brace (3) and both spacer sleeves (3c) are designed as rectangular hollow profiles with the same cross section. The lateral surfaces (3f) of the spacer sleeves (3c) and the lateral surfaces (3g) of the first and second part (3a, b) of the cross brace (3) are aligned with one another. Due to the matching cross section, the congruent end faces on the left and right end faces (3d, e) are flush with one another and cover the entire area.

The connecting profile (8a) is also designed as a rectangular hollow profile and is attached to the inner wall of the first part (3a) of the cross brace (3). The attachment is preferably materially bonded, for example by soldering, welding or gluing. The cross section of the connecting profile (8) is selected in such a way that the inner cross section of each spacer sleeve (3c) can be displaced in the longitudinal direction without play on the connecting profile (8a).

The length of the section of the connecting profile (8a) that protrudes beyond the end face (3i) of the first part (3a) of the crossbar (3) is dimensioned such that it exceeds the longitudinal extension of the two spacer sleeves (3c), so that the free end ( 8c) of the connecting profile (8a) extends sufficiently far into the second part (3b) of the cross brace (3). The cavity in the second part (3b) also forms the receptacle (8b) of the plug connection (cf. 1 ).

For the appropriate width adjustment, the pivoting door (5) has a locking section (5d) and a pivoting section (5e), the recesses (6a) of the locks (6) being arranged on the locking section (5d) and the pivoting section (5e) on the second vertical beam (2) is mounted pivotably between the bearing section (2a) and the first part (3a) of the cross brace (3). The pivoting section (5e) comprises a vertical door pillar (5f) having the bearing pins, an upper horizontal door pillar section (5g) and a lower horizontal door pillar section (5h) as well as lattice bars (5i) extending in the vertical direction between the horizontal door pillar sections (5g,h). . The locking section (5d) also has a short upper horizontal door pillar section (5g) and a short lower horizontal door pillar section (5h).

To adjust the width of the pivoting door (5), in the illustrated embodiment between the locking section (5d) and the pivoting section (5e), two intermediate pieces (5j) that increase the distance are detachably connected to the locking section (5d) and the pivoting section (5e). Each intermediate piece (5j) is also composed of an upper horizontal door rail section (5g), a lower horizontal door rail section (5h) and a door rail located between the two mabschnitte (5g, h) extending lattice bar (5i) formed.

The detachable connection of the two intermediate pieces (5j) with the locking section (5d) on the one hand and the pivoting section (5e) on the other hand takes place via a first and second multi-part threaded rod (9a,b), a first and a second transverse nut bolt (10a,b) with a Threaded hole (10c) into which the threaded rod (9a,b) can be screwed and a first and second sleeve nut (11a,b) each with an internal thread for receiving the threaded rod (9a,b) and a screw head (11c).

The bolt axes of the two cross nut bolts (10a,b) extend vertically in a blind hole adjacent to the end face (5k) of the upper and lower door pillar section (5g,h) of the pivoting part (5e). The upper threaded rod (9a) passes through a hole in the locking section (5d), the upper door pillar section (5g) of both intermediate pieces (5j) and in the upper door pillar section (5g) of the pivoting section (5e) up to the threaded hole (10c) in the upper cross nut bolt (10a).

In the same way, the lower threaded rod (9b) passes through a hole in the locking section (5d) near the lower cross brace (3), the lower door pillar section (5h) of both intermediate pieces (5j) and the lower door pillar section (5h) of the pivoting section (5e) of the Swing door up to the threaded hole (10c) in the lower cross nut bolt (10b).

The internal threads of the upper and lower sleeve nuts (11a,b) are screwed onto the ends of the threaded rods (9a,b) opposite the lower and upper transverse nut bolts (10a,b), the screw heads (11c) of which are on an end face of the locking section (5d). issue.

Centering and connecting frames (12) are arranged between the end faces of the adjacent upper and lower door pillar sections (5g,h), which simplify the alignment and alignment of the pillar sections during assembly.

The longitudinal extent of the upper and lower door pillar sections (5g, h) of the intermediate pieces (5j) corresponds in the exemplary embodiment shown to the longitudinal extent of the spacer sleeves (3c). By inserting a number of intermediate pieces (5j) corresponding to the number of spacer sleeves (3c), the frame width and the pivoting door width can be increased uniformly and adapted to different passage widths of the doorway.
