Abstract

Rotatable child safety lock for furniture which blocks the removal or opening of one or more boxes, drawers or doors, characterized in that it is a disc having an angular recess, the apex of the angled recess and the center of gravity of the disc on opposite sides from the fulcrum.

Description

background

Control systems in which shelf baskets or boxes are stored can be found in many - especially young - households, eg. In the first apartment, in students or young families. Due to their age structure, these households are also a preferred target group for the sale of parental controls. Currently, there is no commercially available child safety device for securing shelf baskets. Therefore, the present invention describes a rotatable lock washer with which the extraction of boxes or shelf baskets from a shelf can be prevented. For this purpose, no commercially available solution is available. In addition, the lock washer prevents the opening of drawers or cabinet doors.

State of the art

Child restraints used to block the opening of a drawer or cupboard doors can be classified as follows: 1.) Fuses that are visibly attached to the outside of the furniture; 2.) Fuses installed hidden / not visible. Both types of fuses are commercially available in many variants.

To 1.) When visually attaching the fuse, a securing component is glued or screwed onto the door or drawer to be closed from the outside and a securing component is glued or screwed onto the surrounding piece of furniture. These two parts are connected together, z. B. by a tape, a movable hook or a clip. Before opening the door or drawer, the two securing components are to be separated from each other. Alternatively, with adjacent cabinet doors, these doors can be locked by connecting the handles of the doors with a padlock or similar mechanism. These variants described here must be actively backed up by the user.

To 2.) When concealed attachment of the fuse, for example, hooks are used, which are glued or screwed from the inside into the door or drawer to be closed. The hooks allow the limited opening of the furniture; before fully opening the furniture, the hook on the inside must be loosened. Alternatively, a locking or unlocking of an internal locking mechanism via a magnetic mechanism, wherein a magnet is held from the outside in front of the furniture.

problem

The security measures described above are suitable for closing hinged drawers or cabinet doors with hinges. However, in a shelf or other piece of furniture shelf baskets or boxes that correspond in size to the shelf about and are not connected via a guide to the shelf, so the above-described security measures can be limited. This is especially true if the storage boxes are made of a material that complicate a reliable attachment of a security component (eg, fabric, cardboard, wicker). Since pieces of furniture are to be secured with a child safety lock, are often in a living room, is also to look for an aesthetic appearance, as well as a simple dismantling.

solution

If you put a basket or a box in a shelf, so the withdrawal can be prevented by attaching a lock washer from the outside of the shelf. This can be z. B. by a screw or bolt, if necessary. With a washer done. The lock washer is rotatably mounted, without or with only a small rotational resistance. It must be wide enough to bridge the existing gap between the shelf and the shelf box and to protrude beyond the edge of the box to be secured and thus prevent the withdrawal. To allow extraction of the box, this disc is to be provided with a recess. By turning the disc with the recess towards the locked box, it is possible to pull out the box. After a box has been put back in the shelf, the disc can be rotated back into the locked position. If the recess and the center of gravity of the securing disk are viewed on opposite sides of the pivot point, then the disk automatically returns to the blocking position when it is rotatably mounted.

Achieved benefits

By attaching a lock washer on the outside of a shelf, the withdrawal of a box placed in the shelf can be successfully prevented.

By the opposite position of the recess and the center of gravity of the disc on opposite sides of the fulcrum, the lock washer moves by gravity automatically returns to the secured position, provided that it is easily rotatable. Compared to the above-described variant of visibly mounted fuses no additional intervention to secure the box, drawer and door is required, thus offering a higher level of security over the existing solutions for securing.

In addition to the protection of boxes with the lock washer described also the backup of drawers or shelves is possible, provided that the drawer or door front is flush or recessed to the outer surface of the shelf to which the lock washer is rotatably mounted. With appropriate positioning of the lock washer on the shelf and by choosing a corresponding recess, up to four elements (eg boxes (e.g. 6 ), Drawers ( 7 ), Door ( 5 )), whereas only one or a maximum of two elements can be secured with conventional fuses. Instead of multiple gluing or screwing only a single screw is required, whereby the surface of the furniture is less strained. At the same time a screw provides a durable and very high stability of the attachment, compared with z. As tape, which is often used for the attachment of parental controls.

The currently commercially available variants of fuses are, for. T. due to the complex structure of a fuse, mostly made of plastic. This can represent a visual impairment in the visibly attached variants on a shelf (or wooden furniture in general). Due to the simplicity of the design of the fuse described here is a production of plastic, but also made of wood materials possible. Since pieces of furniture are often made of wood, or in wood look, here is a visual adjustment of the fuse to the wood furniture with simple means possible. The design of the fuse can be varied and allows the adaptation of the fuse to the cabinet or to the control system and the environment in general in terms of shape, size, material, pattern and possibly a child-friendly design.

Embodiments of the invention

In the following, various embodiments of the lock washers are explained in more detail with reference to the following figures:

1 shows a square lock washer with recess

2 shows the attachment of two lock washers square (top) and round (bottom) basic shape on a shelf.

3 shows the opening of the lock washer; left: all elements blocked; right: an element released

4 and 5 show a variation of the lock washer in the event that the elements to be secured ( 7 ) are not separated by a shelf. In this case, the vertex is at / on the fulcrum. The stability of the disc is determined by a wreath ( 10 ) around the fulcrum.

6 shows lock washers with different basic shapes.

One possible embodiment of the lock washer is based on a square basic form ( 1 ). The angle of the recess in the lock washer can be 90 ° ( 1 ). The vertex ( 2 ) of the recess and the center of gravity ( 4 ) are from the fulcrum ( 3 ) seen from the disc on opposite sides. With this embodiment, up to 4 different boxes, doors or drawers can be secured at the same time.

By attaching the lock washer ( 11 ) on a shelf, various boxes, doors and drawers can be secured. ( 2 ) By turning the fuse through an angle of +/- 45 ° or +/- 135 ° ( 8th ), the recess in the lock washer can be brought into a position that allows the opening of a box, a drawer or a door ( 3 ). The fulcrum is centered on the cross of vertical and horizontal shelf. To ensure a smooth opening of the locked box, drawer or door, make sure that the distance between the pivot point of the locking washer and the recess is no greater than half the thickness of the respective shelf, multiplied by 1.4 (= sin (45 °))

Depending on the design of a piece of furniture are two items to be secured, z. As drawers, not separated by a vertical shelf ( 4 ). In this case, the lock washer ( 9 ) the vertex of the recess very close to or on the fulcrum. The fulcrum is for reasons of stability of a wreath ( 10 ), wherein the diameter of the ring corresponds at most to the thickness of the lateral shelf ( 5 )

Various embodiments of this lock washer can be generated by varying the angle of the recess or by varying the geometric shape underlying the lock washer, z. B. Rectangle ( 12 ), Circle ( 13 ), polygonal ( 14 ), heart-shaped ( 15 ) or Further ( 6 ). The dimensions of the lock washers are dependent on the gap width between furniture and security element, as well as the strength of the shelves. The outer dimension (outer edge length or diameter) can vary between 30 mm and 250 mm and according to the embodiments described here is 100 mm, based on shelf board thicknesses of 16 mm and gap widths of 2 to 20 mm. The distance between the fulcrum of the lock washers and the clearance of the lock washers may vary between 8 mm and 35 mm and, according to the embodiments described herein, is 11.2 mm in terms of shelf thickness of 16 mm (half shelf thickness multiplied by 1.4). The angle α between the legs of the recess must be at least 90 ° and depending on the embodiment can be up to> 180 °, according to a special embodiment ( 16 ) the angle is 230 °.
