Description

The present invention relates to a Gurtbefestigungseinrichtung particular for a high chair for toddlers, comprising a seat attachable belt fastener having a main body which has a receptacle for a retractable in this buckle, which is fixable in this receptacle, further comprising a against the force of a Spring element about perpendicular to the insertion direction of the buckle crushable push button, which sits in its non-depressed position in front of the buckle and blocks the buckle in their recording.

A known from the prior art Gurtbefestigungseinrichtung for a high chair of the aforementioned type is for example in the FIGS. 8 and 9 shown. In the drawing FIG. 8 a section of the seat 70 of the high chair, to which, for example, two such fastening devices 80 are attached, being shown on a belt unit 90 with an inserted into the fastening device buckle 91. The main seat 70 has an inner surface. The fasteners 80 are connected to the inner surface of the main seat 70.

Each fastener 80 has a main body 81, a flexible strip 82 and a push button 83. The main body 81 is securely fixed to the main seat 70 and has an outer surface and a buckle groove formed in the outer surface of the main body 81. The flexible strip 82 is attached to the main body 81 (molded) and has a free end. Of the Push button 83 is attached to the distal free end of the flexible strip 82. The belt unit has a belt buckle 91 which is detachably connectable to the belt buckle recess of the main body 81.

In order for the buckle 91 to move out of the buckle recess of the main body 81, the push button must be pushed in, bending the flexible strip 82 as a whole. Only when the push button 83 is depressed far enough, the buckle 91 from the Gurtschnallenveriefung to the right side in FIG. 8 move out.

However, the flexible strip 82 is formed on the main body 81. The push button is located at the free end of a kind of flexible tongue or tab. When the push button 83 is depressed, a lever force is generated at a position where the flexible strip 82 is formed on the main body 81. Consequently, the deformed flexible strip 82 generates a force that presses the push button 83 firmly against a lower side of the buckle 91 and prevents the buckle 91 from being pulled out. Therefore, it is difficult to take out the buckle 91. Likewise, it is also difficult to insert the buckle 91 into the buckle recess of the main body 81. The handling of this known Gurtbefestigungseinrichtung is thus inconvenient, the balance of power are unfavorable and the flexible strip is subject to wear.

It is a housing provided with a slot-like receptacle, in which the buckle is inserted. The buckle has a tongue with a head which is slidable over a ramp until it engages in a latch loaded by a spring force, so that the buckle is then fixed in the receptacle. Pressing a push button downwards against the spring force unlocks the latch and allows the buckle to be pulled out of the socket. At this known solution, however, the push button is not in the non-depressed position in front of the buckle located in the receptacle, but the push button moves in the receptacle and acts on the latch. The mechanism for locking the buckle has a more complex structure and is prone to failure.

The object of the present invention is to provide a Gurtbefestigungseinrichtung particular for a high chair of the type mentioned available, which allows easy insertion and removal of the buckle.

The solution to this problem provides a Gurtbefestigungseinrichtung the aforementioned type with the characterizing features of the main claim. According to the invention it is provided that the push button is a separate element from the main body, which is movable in the main body and against this against the spring force and which is axially guided in his caused by manual pressing movement in the main body, wherein the push button in his not depressed position in front of the buckle and this blocks in their recording.

Preferably, it is such that the push button is approximately positively received in a recess of the main body and axially guided during its movement.

Furthermore, the push button is preferably acted upon on its underside by a separate spring element for this.

The object according to the invention is preferably achieved structurally in that the pushbutton has approximately in the lower region a stop element, in particular in the form of a circumferential collar, through which a stop for the push button in its upper end position is provided. The push button is thus pressed by the spring element up against the stop.

A particularly preferred development of the invention provides that the main body comprises an upper housing part and a lower housing part, which can be connected to one another by fastening means, wherein the receptacle for the belt buckle is located on the upper housing part.

The recording of the fastening device for the buckle usually has lateral guide elements for the buckle, so that it is inserted as in a kind of groove. However, the receptacle is preferably open at the top, so that a belt loop fastened to the buckle, which is located at the end of a so-defined belt, can be led away from the buckle upwards or laterally.

In a preferred embodiment of the invention, it is for example such that it comprises a slide which is arranged in the insertion side opposite end portion of the receptacle, said slider is acted upon by a spring force and presses in the retracted position of the buckle against this against the insertion direction , Preferably is the slider inserted in the front end portion of the main body in a receptacle in which it is acted upon by the back of a spring element and guided in the insertion direction. Preferably, therefore, in the retracted position, the buckle between the slider at its insertion end and an abutment surface of the push button is clamped at its rear end.

The lower housing part may for example have a receiving area with an abutment surface for a spring element, which acts on the underside of the push button.

First, on the FIG. 1 Reference is made, and by way of example, a high chair 10 is described, in which the Gurtbefestigungseinrichtung invention is used. The high chair 10 for children comprises a foot 11 and a pillar 12 protruding upward from this foot, on the upper end of which the seat 13 of the highchair 10 rests. This seat has a back surface 131, which merges into a seat in a curvature. Attached to the back surface 131 in the present example are two belt units 14, which respectively comprise straps 142, which serve to fasten a child sitting in the highchair 10. In order to fasten the straps 142 to the back surface 131, fastening devices 20 used in each case in the back surface 131 are used.

Below is on the Figures 2 and 3 Referenced. In FIG. 2 an exemplary fastening device 20 according to the invention is shown by itself in perspective. In this fastening device for a belt, a buckle 141 is used. The front insertion end is denoted by 1411, while the opposite (in the insertion direction) rear end is denoted by 1412. The buckle 141 is also in FIG. 3 shown here, the end of a belt 142 is shown, the end of which is pulled in a loop through the buckle 141 and thus secured thereto. You can see in FIG. 3 also the insertion direction of the buckle in the fastening device, wherein the insertion end 1411 is the front when inserted. The main body of the in FIG. 2 shown fastening device 20 is in FIG. 3 denoted by 21.
Out FIG. 1 it can be seen that the ends of the straps 142 on which the buckles 141 are located, are fixed to the back surface, while the free ends of the straps can be seated used to buckle a child. On the structural design of the seat and the highchair it does not matter in the context of the present invention. These can be designed in many areas, apart from the belt fastening device according to the invention in many areas. Reference is made to conventional designs of children's high chairs which are familiar to the person skilled in the art.

The fastening devices 20 for fastening the belt according to the invention are preferably used in depressions or receptacles in the back surface 131 of the highchair seat 13. The structure of the fasteners 20 will now be described in detail below with reference to FIGS FIGS. 2 to 6 explained in more detail. The fastening devices 20 comprise a main body 21 (see FIG. 3 ), a push button 22, a spring member 23 associated therewith, a slider 24, and another spring member 25 associated with the slider 24. The main body 21 has an upper housing part 21A and a lower housing part 21B, which are joined together. In the upper housing part 21 A is a receptacle 211 for a buckle 141, which is inserted there. For this purpose, the receptacle 211 at the insertion side 2111 is open, while the receptacle 211 is closed at the insertion side 2111 opposite end 2112 by a transverse wall or a transverse web. The bottom of the groove-like receptacle 211 is in figure 3 designated 2113. On the upper side opposite the bottom 2113, the receptacle 211 is partially open, wherein the fastening device 20 is mounted in the seat 13 so that this open side faces the seat surface and as shown in FIG FIG. 1 sees, the specified belt 142 can escape there.

The push button 22 is how to particular FIG. 2 takes in the area of the open side 2111 of the receptacle 211, ie where the belt buckle 141 is inserted. The push button 22 is relative to the plane of the bottom 2113 of the receptacle 211 and perpendicular to the extension of the bottom against the force of the spring element 23 (see FIG. 3 ) displaceable, so that the push button 22 is retractable when exerting a compressive force from above quasi in the bottom 2113. FIG. 2 shows the raised normal position in which the push button is due to the spring force of the spring element 23, which acts on him from below, is in an upper position, thus blocking the open insertion side 2111 of the receptacle 211. The push button 22 is how to get in FIG. 3 Detects detected in a recess in the bottom 2113 so that it is guided in this when pressed down. Here is preferred for effective guidance a positive connection for the push button 22 is given in its recess, which is also in FIG. 4 can recognize. Here is to be noted that FIG. 4 the fastening device of FIG. 3 not only turned from the bottom but also rotated by about 180 °, so that in FIG. 4 the push button 22 is located on the other side compared to the Figures 2 and 3 ,

The push button 22 has an approximately semicircular outline and comprises an upper part 221 and a lower side opposite the upper part radially outwardly projecting collar 222 which is pressed in the normal position of the spring element 23 upwards to the underside of the upper housing part 21 A (for Understanding here on the Figures 3 and 4 The upper part 221 is pressed upon depression of the push button 22 in the in FIG. 3 recognizable recess out. With inserted buckle 22 (see FIG. 2 ) abuts the rear end 1412 of the buckle 141 at an abutment surface of the upper part of the push button 22, since the push button 22 due to the spring force of the spring element 23 after the insertion of the buckle 141 again pushed so that the push button blocks the buckle 141 against unintentional pushing out of its receptacle 211 and thus secures. Only when you push the push button 22 back down, the buckle 141 can be pushed out of their recording (groove) again.

Furthermore, a slider 24 is provided, which is slidably received in an end-side receptacle 2112 at the opposite end of the receptacle 211 of the buckle. When inserting the Gurtschnalle141 this slider 24 is acted upon against the force of the spring element 25 and pressed in the end position of the buckle a little in his frontal recording into it. In the retracted end position of the buckle 141, this is thus pressed against the re-bearing surface of the push button 22. After the buckle has reached its final position when inserted results in a constructive training a kind Einrasteffekt in which the rear end 1412 of the buckle 141 almost snaps behind the push button 22, which moves up and behind the buckle, with the buckle through the slider 24 is still pressed against the insertion direction against the push button.

The slider 24 has a projecting portion 241 which projects from the front side into the receptacle 211 (see FIG. 2 ) and an abutment area 242 (see FIG. 3 ), which lies behind the transverse wall of the end 2112 of the receptacle 211 (see also FIG. 4 ), whereby the slider is held in its protruding into the receiving position (without buckle in the receptacle 211) by the force of the spring member 25 in position and pressed against a stop. If then the buckle 141 is inserted, only the projecting portion 241 is pressed against the force of the spring element 25, but only so far that the projecting portion 241 still protrudes into the receptacle 211 a bit.

The two spring elements 23 and 25 need not necessarily be coil springs, but may for example be other types of springs, bent metal strips, plastic parts made of elastomeric material or the like. The shape and size of these spring elements 23, 25 is not critical in the context of the present invention.

The Figures 5 and 7 show how the buckle 141 is pushed out of its receptacle 211 out. In the sectional view according to FIG. 7 can one compare with FIG. 6 clearly recognize how the buckle 141 pushes the push button 22 while you in FIG. 6 , which represents the inserted position, sees how the inserted slider 24, the spring element 25 pushes and biases, whereas it is in FIG. 7 is relaxed. In FIG. 6 one recognizes further well how the specified buckle 141 is clamped in the retracted position, as it were, between the slider 24 on one side and the push button 22 on the other side, so that an unwanted automatic release of the buckle 141 from its retracted position is not possible. Only when the push button 22 is pressed down, it is possible to push the buckle 141 out of its receptacle 211 out. However, once the buckle 141 is pushed over the push button 22, it is easy to take out the buckle.

• Es ist mit wenig Kraft möglich, den Druckknopf 22 einzudrücken, so dass das Einschieben und Herausziehen der Gurtschnalle 141 einfach zu bewerkstelligen ist. Demgemäß kann der Benutzer die erfindungsgemäße Vorrichtung leicht handhaben. Der Schieber 24 drückt gegen die Gurtschnalle 141 und schiebt diese aus Ihrer Aufnahme, sobald der Druckknopf 22 manuell herunter gedrückt wurde. Somit wird beim Herausnehmen der Gurtschnalle das sich wieder nach oben bewegen des Druckknopfs 22 verhindert. Das Herausnehmen der Gurtschnalle ist daher für den Benutzer sehr bequem.

From the above, it can be seen that the present invention has the following advantages:

• It is possible with little force to depress the push button 22, so that the insertion and withdrawal of the buckle 141 is easy to accomplish. Accordingly, the user can easily handle the device of the invention. The slider 24 presses against the buckle 141 and pushes it out of your receptacle as soon as the push button 22 has been manually depressed. Thus, when removing the buckle, the move up again of the push button 22 is prevented. The removal of the buckle is therefore very convenient for the user.

The structure of the belt fastening device according to the invention is very compact, can be easily mounted and is easy to handle.

In the foregoing description, numerous features and advantages of the present invention have been described in connection with the structure and function of the device of the invention. However, these statements are only to be understood as examples and changes in details, in particular concerning the Shape, size and arrangement of the parts of the device are possible without departing from the scope of the invention. The latter is determined by the features mentioned in the following claims.
