Description

[01] Technical Field

[02] The utility model relates to furniture structures, namely, to a device for fastening elastic elements of the furniture base and can be used for detachable fixing of S-shaped springs (“snake”) on metal frames of upholstered furniture for sitting and lying.

[03] Background

[04] A number of designs of mounting devices for springs and other elastic elements are known in the art. In particular, in the RF patent for utility model RU181115, 07/04/2018 a fastening device is disclosed that has a body with two hook-shaped elements (hooks), one of which is designed to hold the spring, and the second is for fixing in the cutout of the furniture frame. However, such designs have a significant drawback associated with the possibility of accidentally disengaging the device from the spring during operation.

[05] The closest analogue of the utility model is the device for attaching springs described in the patent of the Russian Federation for utility model RU181121, 07/04/2018. The specified device has a housing with a through hole for accommodating the end of the spring, as well as means for engaging the housing on the upper wall of the tubular frame, made in the form of a hook-shaped element placed in the hole of the frame. The disadvantage of the closest analogue is the risk of involuntary separation of parts of the elastic base, associated with a tendency to destruction of the protruding elements of the fasteners, as well as the disengagement of the elements during long-term operation.

[06] Disclosure of the essence of the utility model

[07] The objective of the utility model defining the technical problem is to provide the possibility of detachable fixation of the elastic elements of the furniture base with a high degree of operational reliability.

[08] The technical result of the utility model is to increase the reliability of the detachable connection of the elastic element with the furniture frame. An additional advantage of the utility model is the ability to install elastic elements both with an interference fit (for springs) and aback (for flexible lamellas) and the arrangement of elements flush with the base frame.

[09] The specified technical result is achieved in a utility model due to the fact that the device for attaching the elastic element of the furniture base includes a housing in which a through hole is made to accommodate the end of the elastic element, as well as means for releasably fixing the case on the wall of the furniture frame, this tool is made in the form of a slotted groove.

[010] In addition, to achieve a technical result, there are private options for implementing the utility model, according to which:

[011] the housing is made tapering in height, while the slotted groove extends from the narrow part of the housing to its wide part;

[012] the length of the slotted groove is 50-90% of the height of the housing;

[013] the housing is in the form of a triangular prism;

[014] the housing is configured to accommodate a tubular furniture frame in an angular cutout when placing a side wall of said tubular frame in a slotted groove of the housing;

[015] the housing has a stop, made with the possibility of interaction with the upper wall of the tubular frame when placing the housing in the specified angular cutout,

[016] the housing in the area of the through hole has a bevel.

[017] In the claimed design for securing the end of the spring, a through hole is provided, which, unlike the hook, provides reliable retention of the elastic element without the risk of slipping out during operation. In this case, in contrast to the closest analogue, a slotted groove of the housing acts as a means of detachable fixing of the device on the frame wall. The specified groove has obvious advantages compared to the hook-shaped element, since the device is less susceptible to destruction during long-term operation and can be more firmly held on the frame wall due to the tensile forces of the elastic element.

[018] Thus, all of the features of the utility model are aimed at achieving the declared technical result.

[019] These particular forms of implementing the utility model further increase the reliability of the connection. However, they are not strictly mandatory, since the technical result can be achieved without the use of these additional features.

[029] Implementation of the utility model.

[030] The claimed device is a clip for detachably fixing an elastic element. The device includes a housing (1) with a through hole (2) to accommodate the end of the elastic element (3) of the base, as well as a slotted groove (4) for fixing the housing to the wall of the furniture frame.

[031] The housing (1) is preferably made in the form of a tapering element, while the slot groove (4) extends in the center of the housing (1) from the narrow (sharp) part towards the wide part (base). The depth of the groove (4) is preferably not less than half and not more than 90% of the height of the housing (1), which ensures the most reliable retention of the device on the frame wall without the risk of destruction of the housing.

[032] The most optimal is the implementation of the housing (1) in the form of a triangular prism with a rectangular base and triangular side walls. However, other housing options are possible, for example, in the form of a cone (regular or truncated), a quadrangular prism, etc.

[033] The furniture frame of the elastic base on which the claimed device is mounted preferably includes a tubular element (5) of a square or other section in which an angular cut-out (6) of a rectangular shape is made (Fig. 4). The wall thickness of the tubular element (5) corresponds to the width of the groove (4) In this case, the housing (1) and the slotted groove (4) are made in such a way that the claimed device can be placed in the indicated angular cutout (6) and engage on the side wall (7) tubular element (5), which is the wall of the furniture frame (see Fig. 5,6). The specified wall (7) is placed in the slotted groove (4) of the housing (1) (see Fig. 6).

[034] To provide a more reliable fixation of the housing on its lateral inclined surface, a stop (8) in the form of a bevel can be made, which interacts with the upper wall (9) of the tubular element (7) forming the furniture frame.

[035] The elastic element (3) of the furniture base can be, in particular, an S - shaped spring (in the form of a "snake"), an elastic belt, a flexible lamella, etc. For ease of installation of the bent end of the elastic element (3) and its more secure fixation in the hole (2), the housing in the area of the hole (2) may have a chamfer (10) formed by the bevels of the side surfaces in the direction of the central part. The hole (2) for accommodating the elastic element (3) may have an oval, round, rectangular or other cross section.

[036] The device operates as follows.

[037] The ends of the elastic element (3) (for example, springs), put on the claimed device. First, one device is fixed on one side of the frame by placing the housing (1) in the cutout (6) and meshing it with the side wall (7). Next, the elastic element (3) stretch and similarly fasten the second device on the other side of the frame. As a result, the elastic element (3) is held on the frame due to elastic tensile forces. The presence of a stop (8) in contact with the upper wall (9) in the corner cutout (6) prevents the housing from displacing during operation, which further increases the reliability of the detachable connection.
