Abstract
Description
[0001] FIELD OF TECHNOLOGY
[0002] The utility model relates to the field of construction and interior design, and more specifically to connecting fittings for a corner compensator with a spring mechanism.
[0003] STATE OF THE ART
[0004] From https: / / web.archive.org / web / 20260227041053 / https: / / laconistiq.ru / micro_plintus, a micro skirting board is described—a long profile used to cover the gap between the bottom edge of a wall and the floor covering. A micro skirting board placed around the perimeter of a room creates a subtle, contrasting line, offering an alternative to solutions with raised, raised skirting boards (upward and away from the wall). Recessing the skirting board attachment relative to the wall plane allows for a slightly larger room compared to traditional skirting boards.
[0005] Conventional micro skirting boards are secured around the perimeter of a room by inserting a spring into a groove. One side of the spring rests against the edge of the flooring (there is an expansion gap between the edge of the flooring and the wall), while the other side rests in the groove, thereby pressing the micro skirting board against the wall. However, in conventional solutions, in room corners or on straight sections (where the skirting boards are insufficient and are joined in a straight line), the micro skirting boards are not mechanically connected, providing only a visually smooth transition at an angle of 0 or 90 degrees, etc. Moreover, it is precisely along the edges of the micro skirting board sections that the highest risk of divergence occurs, which is fraught not only with purely decorative defects but also poses a risk of injury, as the protruding ends of the micro skirting board are typically roughly processed and sharp. In addition, the gap between the baseboards is a gateway for dirt, dust, and detergents to enter the space between the floor covering and the wall.
[0006] In this regard, there is a need for means that would ensure a reliable connection of the ends of the micro skirting boards to each other at different angles.
[0007] ESSENCE OF THE UTILITY MODEL
[0008] We offer a device, a connector, which, when used, implements a new method of connecting one or two micro-skirting profiles “compensator with spring” into a single rigid unit.
[0009] When the connector has two micro skirting board guides, it can be used to firmly connect these micro skirting boards in a line or at an angle depending on the location and relative orientation of the guides.
[0010] If the connector has only one guide, then it can be used as a plug, which on one side is firmly connected to the baseboard itself, and on the other hand, the plug itself and, as a result, the end of the micro-baseboard can be firmly fixed to a wall or other stationary building structure.
[0011] The objective of the utility model was to create a connector that would be characterized by a combination of the following advantages:
[0012] - ensuring high rigidity of the connection between the end of the micro-plinth and the connector during torsional deformations relative to the connection axis,
[0013] - ensuring high strength during inevitable bending and impacts during installation and operation,
[0014] - ensuring high accuracy of positioning of micro skirting boards “in one line”, “at an angle of 90 degrees” and / or “in one plane” (depending on the location of the guides) even if the end of the micro skirting board is cut with a slight deviation from 90 degrees due to high rigidity to torsion and bending,
[0015] - ensuring the masking of the end of the micro-plinth (due to which the unevenly cut end of the micro-plinth is located behind the front surface of the plate, is not visible after installation, its dimensions do not visually change with small discrepancies between the end of the micro-plinth and the connector that are inevitable during installation, there is no risk of injury on the rough surface of the end when touching the joint) and its location in one line with the guide, even if the end of the micro-plinth is cut with a slight deviation from 90 degrees.
[0016] The main technical result of the utility model is to create a connector that has high rigidity and strength.
[0017] The above mentioned problems are solved due to the fact that the proposed connector for a micro skirting board having two shelves, namely, a first shelf and a second shelf, which are oriented at an angle to each other, which has a longitudinal groove having a wide and a narrow part, wherein its narrow part is formed on one side by a protrusion on the inner surface of the first shelf, and on the other side by a counter L-shaped protrusion on the second shelf, includes:
[0018] a plate element having a front surface and a back surface,
[0019] a guide having a proximal portion located on the back side of the said plate element and a longitudinally elongated distal portion connected to it,
[0020] characterized by the fact that it contains:
[0021] said distal portion of the guide has a first and second side and is provided with first and second longitudinal grooves located on the first and second sides, respectively, in such a way as to ensure docking with the corresponding protrusions forming the narrow portion of said groove of the micro-plinth,
[0022] said distal portion of the guide on its first side is provided with a first support shelf located with the possibility of ensuring a tight fit to the inner surface of said first shelf of the micro-plinth,
[0023] the said distal portion of the guide on its second side is provided with a second support shelf, located with the possibility of ensuring a tight fit to the outer surface of the said L-shaped protrusion on the second shelf of the micro-plinth,
[0024] said proximal portion of the guide is located at a predetermined distance from the edge of the plate element,
[0025] said distal part of the guide is connected to said proximal part of the guide in such a way that between the back side of the plate element and the first support shelf of said guide, a gap is provided corresponding to the thickness of the first shelf of the micro-plinth.
[0026] In one preferred embodiment, the connector may include only one of the aforementioned guides. This option is suitable as a plug when securing the end of one micro-baseboard is necessary, but connecting it to another micro-baseboard is not required. It should be understood that in this text, the term "connector" is used in a broad sense and covers both cases where the connector serves to connect two micro-baseboards and cases where it attaches to only one micro-baseboard and serves as its end piece.
[0027] In another preferred embodiment of the connector, the longitudinal axis of the distal end of the guide may be parallel to the plane of the said plate element.
[0028] In another preferred embodiment of the connector, said distal end of the guide may have a third side with a flat surface, located in such a way as to ensure the possibility of tightly fitting to the flat inner surface of said second shelf of the micro-plinth.
[0029] In one preferred embodiment of the connector, the cross-sectional shape of the distal end of the guide and the micro-plinth may be unchanged along their longitudinal axis.
[0030] In another preferred embodiment of the connector, the width of said support plates may be from 3 to 10 mm.
[0031] In another preferred embodiment, the connector may include the two mentioned guides.
[0032] In a particularly preferred embodiment of the connector, the guides are oriented at a predetermined angle relative to each other.
[0033] In an even more preferred design, the connector guides are oriented at 90 degrees relative to each other. This allows for connecting sections of micro skirting board at walls with 90-degree dihedral angles.
[0034] In one preferred embodiment of the connector, the guides can be oriented at a 0-degree angle relative to each other. This allows for the micro skirting boards to be connected in a single line.
[0035] In one of the preferred forms of execution of the connector, the said first shelf of the micro-plinth may be narrower than the second.
[0036] In an alternative embodiment of the connector, the said first shelf of the micro-plinth is wider than the second.
[0037] In another preferred embodiment of the connector, said first and second shelves of the micro-plinth are oriented at an angle of 90 degrees to each other.
[0038] The shape of the plate element may vary. However, in a particularly preferred embodiment of the connector, said plate element has a rectangular shape.
[0039] Next, the utility model will be illustrated using the example of some specific embodiments.

[0051] IMPLEMENTATION OF A UTILITY MODEL
[0052] As shown in Fig. 11 and 12, a connector for a micro skirting board having two shelves, namely, a first shelf and a second shelf, which are oriented at an angle to each other, and which has a longitudinal groove having a wide and a narrow part, wherein its narrow part is formed on one side by a protrusion on the inner surface of the first shelf, and on the other side by a counter L-shaped protrusion on the second shelf, includes
[0053] a plate element having a front surface and a back surface,
[0054] a guide having a proximal portion located on the back side of the said plate element and a longitudinally elongated distal portion connected to it.
[0055] The said distal portion of the guide has a first and a second side and is provided with first and second longitudinal grooves located on the first and second sides, respectively, so as to ensure docking with the corresponding protrusions forming the narrow portion of the said groove of the micro-plinth.
[0056] The said distal portion of the guide on its first side is provided with a first support shelf, located with the possibility of ensuring a tight fit to the inner surface of the said first shelf of the micro-plinth.
[0057] The said distal portion of the guide on its second side is provided with a second support shelf, located with the possibility of ensuring a tight fit to the outer surface of the said L-shaped protrusion on the second shelf of the micro-plinth.
[0058] The said proximal portion of the guide is located at a predetermined distance from the edge of the plate element.
[0059] The said distal part of the guide is connected to the said proximal part in such a way that a gap corresponding to the thickness of the first shelf of the micro-plinth is provided between the back side of the plate element and the first support shelf of the said guide.
[0060] Regardless of the specific type of connector (different types are shown in Fig. 1-10), the method of connecting them to the micro skirting board is based on a single principle.
[0061] Each connector has a plate element with an outer (front) and a rear (back) side. On the rear side of the plate element, there are guides (parallel or perpendicular to each other) with a cross-section that matches the shape of the groove in the micro skirting board profile (the cross-sections of the guide and groove are congruent).
[0062] The guide cross-section profile is designed such that when the micro skirting board is inserted, it tightly fills the cavity of the micro skirting board groove where the spring is located, and also envelops the groove on the side facing the spring, thus enveloping the technological groove. This ensures maximum fixation of the elements relative to each other.
[0063] Furthermore, as seen in Figs. 11 and 12, on the back of the plate element, where the foot is attached, there is a recess (quarter recess) approximately 1.5 mm deep, which serves to receive the visible (front) portion of the micro skirting board when it is inserted onto the guide. This recess conceals the potentially dangerous end of the aluminum profile and provides additional security for the inserted profile. This design feature improves user safety compared to joining micro skirting boards without additional connectors, which can lead to joint separation over time.
[0064] Because the proximal part of the guide extends from the edge of the plate, even with inevitable errors when cutting micro skirting boards (deviations in the length of the micro skirting board section or in the angle of the cut), no visually noticeable or dangerous gaps arise, ensuring the rigidity of the structure. At the same time, the joint remains detachable, allowing for easy replacement of one of the profiles.
[0065] By creating a single continuous connection along the entire contour, the strength of the connection between the micro skirting board and the floor covering is also increased, and unplanned and uncontrolled “jumping” of the profile out of the technological groove where the micro skirting board is installed is prevented, due to the rigid fastening of the profiles to each other and the expansion of the springs in different planes.
