Abstract

Two at least partly plastic components (1,2) are connected by a releasable rigid coupling with two edges (4) and two lips (7). The edges form a wall of one component and the boundary of hole(s) in the wall. The lips are inserted into the hole(s) and snap fit with the edges. The coupled lips and edges can be released by rotation. A minimum force in a rearward direction is necessary to displace the coupled parts. The parts may be of acrylonitrile butadiene styrene or polypropylene.

Description

Modular Assembly Structure

Conventional assembling structure, such as those described in US Pat. No. 3,195,266, for example, there is a problem in that such a conventional assembly structure is a complex separation between the various parts, in order to separate the connection state As a result, a large force acts on both ends of the connection at the same time, thereby actually separating in the axial direction.

Moreover, the prior art assembly of the above-mentioned US patent has not always been smoothly connected, even if the connecting member between the parts is rattled and is not separated.

The present invention relates to a modular assembly structure for use for educational or toy play, for example, and a modular assembly structure composed of at least two parts to be detachably connected to each other by a connecting means.

Here, the connecting means includes at least one connecting end that forms part of the wall of one part and forms a boundary of one or two continuous holes of the wall, and at least one for interacting with the corresponding connecting end respectively inserted into the continuous hole. It consists of two lips which have the above clasp tips and are movable backwards with minimal force applied in the direction of moving backwards due to the interaction of these parts.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

An object of the present invention is to provide a modular assembly structure that solves the above conventional drawbacks, the assembly structure according to the present invention is to rotate around one part of the connection surface is separated contact between the other parts of the connection surface The center of these connection surfaces is in the form of a connection between the connection ends and the connection ribs which are engaged to be pressed against each other.

The stop surface connected to one connecting lip is pressed so as to be connected with a constant force against at least one of the connecting ends so that there is no gap between the parts, and the parts are partially made of synthetic resin.

In a preferred embodiment of the present invention, the connecting surfaces have a convex shape. In another embodiment, the connecting end and the connecting lip have inclined pressure surfaces on their sides spaced from the connecting surfaces, The faces are adapted to slide one another so that the connection is effected effectively when pressure is applied, so in this embodiment the connection is made by pressure application depending on the inclined position. The coefficient of friction of the surfaces sliding against each other and the flexibility of the ribs determine the required pressure, even when the parts are separated. And the pressure surfaces usually have a convex shape. The connecting surface and the working surface also have a convex shape that is advantageous for the connecting lip and a part of the connecting end to interact.

In addition, the present invention is that the connecting end and the connecting ribs are flat so that the connected parts can not rotate relatively, while the stop surface forms a part of the flange plate.

Here, the flange plate is made of permanent magnets, and these ferromagnetic components are magnetically connected to the structure. In addition, if necessary, the flange plate is fitted to fit the groove at the end of the connection, when used as the flange plate is fitted in the groove.

In another embodiment of the present invention, one part has two sets of connecting lips on both sides of the flange plate and a groove depth corresponding to half the thickness of the flange plate so that the two parts connected by the one part are At least in contact with each other is located at their connection end.

In addition, the present invention is provided with a tensioning means for the position of the connecting ribs directly, and after the tensioning means is connected to have a large tensile force is inserted so as to be movable only to the rear, the tensioning means to the control means Can be adjusted from the outside.

In the embodiment of the present invention, the control means are provided with indicator means for the actuation and non-operational state of the tension means, which means can be embodied as colored code means, for example.

The assembly according to the invention consists of synthetic resins such as ABS or polypropylene (PP), for example, and the use of very strong synthetic resins such as ABS has the advantage of prolonging the life of components even when used roughly for a long time. There is this. And ABS plastics are great when the parts don't need clamps or clasp connections.

In the case where material elasticity is required, in particular in the case of a clasp or clamp connection, a softer, ie polypropylene synthetic resin which requires more elasticity is preferable.

Such plastic parts are made by injection molding, and parts manufactured by extrusion molding are divided into parts of a footnote rod, if necessary, and selected removal of a certain area is performed. Here, prismatic means a shape having the same cross-sectional shape in the transverse direction of the basic direction at an arbitrary position.

According to the invention, in the drawings, functionally identical parts are denoted by the same reference numerals as much as possible.
