RU206083U1 - ELASTIC CLIPS - Google Patents

Abstract

The utility model relates to the structures of prefabricated locks and can be used, for example, in the industries of toys, furniture production, and ironmongery. An elastic clip, intended for connecting parts of constructors, is at least one shelf base of the fastening clip, from which at least two springy walls of the fastening clip emanate, having external and internal surfaces, while each of the springy walls has at least one fixing hook, there are limiting protrusions on the inner side of each wall. On the outer surface of each springy wall there is also a limiting hook with an overhang of at least 1.5 overhang of the fixing hook, and the thickness of the base flange is in a certain way correlated with the width of the clip.

Description

The utility model relates to the structures of prefabricated locks and can be used, for example, in the industries of toys, furniture production, and ironmongery.

From the patent of the Russian Federation No. 130476, a film fixer in a profile is known, consisting of an elastic bracket and an element wedging the bracket, while the profile and the elastic bracket of the clamp have corresponding depressions and protrusions for mutual fixation when wedging, the upper parts of the walls of the elastic bracket of the clamp protrude outward of the base fastening profile, and also have projections inward.

The closest analogue is known from the patent of the Russian Federation No. 2729295 "Panel with at least one flexible material (options), methods and clips for fastening and fixing flexible material (options)" with flexible material, characterized in that the spring fastening clip is made of a hard elastic material, is at least one shelf-base of the fastening clip, from which at least two springy walls of the fastening clip emanate, having the outer surfaces of the fastening clip and the inner surfaces of the fastening clip, wherein each of the springy walls of the fastening clip has at least one fixing hook of the fastening clip on the outer surface of the fastening clip, and the fixing hooks of the fastening clip can be a continuation / component / section of the springy walls of the fastening clip.

The specified fastening clip may have a curved shelf-base; shelf base with springy properties; mounting handles at the top of the spring walls; at least one pair of fixing protrusions on the inner surface of the fastening clip; pressure shelves in the lower parts of the spring walls.

The disadvantage of the clip according to the specified patent is the uncertainty of the clip resource under flexion-extension conditions. In addition, the complex shape increases the likelihood of defects in the form of stresses and cracks in the areas of transitions between the clip elements and, as a consequence, premature destruction of the clip.

The task of the utility model is to increase the service life of the clip. The problem is solved due to the clip design.

An elastic clip, intended for connecting parts of constructors, is at least one shelf base of the fastening clip, from which at least two springy walls of the fastening clip emanate, having external and internal surfaces, while each of the springy walls has at least one fixing hook, there are limiting protrusions on the inner side of each wall. This design is well known and very common for clips. The problem of increasing the resource is solved due to the fact that on the outer surface of each springy wall there is also a limiting hook with an overhang of at least 1.5 overhang of the fixing hook. This restricts the movement of the clip in the abutment and reduces the likelihood of over-compression of the clip. The task is also achieved due to the fact that the thickness of the base flange is in a certain way correlated with the width of the clip, and the value of the ratio of the thickness of the base flange to the width of the elastic clip in percent is selected depending on the material from the following ranges:

Solid wood 11-12% Medium density plastic 15-20% High density plastic 10-13%

Due to this, an increased number of compressions and releases is achieved while ensuring the operability of the elastic clip.

Description of figures

Figure 1 shows a general view of the elastic clip: 1 - base shelf, 2 - fixing hook on the outer side of the wall, 3 - limiting protrusion on the inner side of the wall, 4 - limiting hook on the outer side of the wall, 5 - stop for the clip in the parts to be joined ... The arrow indicates the direction for seating the clip and fixing the parts.

Implementation of the utility model

An elastic clip can be made of a hard elastic material, for example, wood of various kinds, plastics of medium density, high density. Depending on the material, the ratio of the thickness of the shelf-base and the width of the elastic clip is selected from the following ranges:

Laminated wood (plywood) 13-15% Solid wood 11-12% Medium density plastic 15-20% High density plastic 10-13%

The transitions between the planes are made rounded.

As a result, the service life of an elastic clip made in accordance with the claims for various materials can be estimated as follows:

Claims (2)
