Description

The utility model relates to fastening and shock-absorbing devices and can be used to protect the edges, faces and corners of an electronic device from vibration or shock loads during operation.

When selecting shock-absorbing angles, the following issues are addressed: the angle's weight, the ease of use of the device with the angles installed on it, operating conditions that affect the material from which the angle will be made, dynamic and static load factors, installation methods, ease and cost of manufacture.

When using the corner, the reliability of protection and the quality of attachment to the parts of the device’s mounting area are of great importance.

A device is known, described in the description of the patent for invention No. US 9598217 “Packaging for edge-sensitive cargo”, intended for packaging fragile cargo, such as sheets of glass, slabs of natural stone, etc., which is used for transporting cargo sensitive to external influences.

The disadvantage of the known device is that it cannot be used when operating instruments, since it is not a universal protective device, but serves as protection only during the transportation of fragile goods.

The closest analogue in technical essence to the proposed one is the corner bumper according to the patent for invention No. US 11253037 “Corner bumper”, A45C 13/36, A45C 11/00, B65D 81/05, A45C 5/00, adopted as a prototype.

The prototype corner bumper consists of a single body with protruding legs, an insert with a hole for mounting to the device body, and intersecting sidewalls adapted for mounting on the outer corner of a rigid case or container. The corner bumper is configured to attach to the corner of a carrying case, container, or similar device and acts as a shock absorber to mitigate damage to the case and its contents from external impact.

The disadvantage of the prototype device is that the shock-absorbing protrusions, which serve as legs, are located only on one of the three protected edges. When the product is folded over onto its inner side, the bumper cannot adequately protect the product. Also, the corner is not interchangeable when installed at different angles (at least two variations of the corner are used for installation on the device).

The objective is to ensure universal protection of the device body corner.

In order to solve the stated problem, in the shock-absorbing corner, containing a housing with protruding elements, an insert for fastening to the housing of the device, according to the utility model, the corner is made in the form of two volumetric trapezoidal platforms, connected to each other by a central U-shaped profile in the form of a trapezoid in cross-section and performing the role of a vertical center of symmetry, while the protruding elements are perpendicular projections-grooves, performing the functions of legs and stiffening ribs, and in the middle part of the housing there is a through hole, in addition, the metal insert is made of a symmetrical trapezoidal shape with two cylindrical projections and two cylindrical projections with threaded holes for hidden fixation on the housing of the device with threaded fasteners.

The general appearance of the claimed device is shown in Fig. 1, where the following designations are used:

1 - corner body;

2 - smaller platform (upper);

3 - larger platform (lower);

4 - metal insert;

5 - U-shaped profile with protrusions and grooves;

6 - trapezoidal grooves (legs).

Fig. 2 shows an image of a metal insert, where it is indicated:

4 - metal insert;

4.1 - cylindrical protrusions;

4.2 - protrusions with threaded holes.

Fig. 3 shows the corner body in different projections, where it is indicated:

3.1 - shaped groove;

3.2 - hole for additional fastening of the corner with fasteners.

The body of the corner is made of a polymer mixture and is two three-dimensional trapezoidal platforms (a smaller platform (upper) 2 and a larger platform (lower) 3, containing perpendicularly located trapezoidal protrusions-grooves 6, connected to each other by a central U-shaped profile 5 with protrusions-grooves (Fig. 1). The trapezoidal shape of the protrusions-grooves of the central U-shaped profile 5 and the protrusions-grooves 6, containing already laid slopes, allows for the easy removal of the corner from the mold, ensuring the technological efficiency of the manufacturing process. In the middle part of the body there is a through hole for fastening additional structural elements, while these elements will not interfere with the protection of the corner of the device from impact loads. The larger trapezoidal platform 3 is a three-stage structure for mounting on the lower part of the corner of the device. A metal insert 4 is mounted in the lower platform 3 (Fig. 2), with Two cylindrical projections 4.1 at one level, acting as guide bushings, and two projections with threaded holes 4.2 for concealed fastening with screws at another level. On the side faces of the lower platform 3, there is one projection-groove (leg).

The smaller trapezoidal platform (upper) 2 represents a two-stage design. The upper platform 2 has a shaped groove (channel) 3.1 (Fig. 3), which is designed for fixation to the device housing projection and serves as part of the bracket fastening to the upper part of the device corner. Platform 2 also has a hole for additional fastening of the bracket with fasteners (not indicated in Fig. 1). On the lateral edges of the upper platform 2, one projection-groove (leg) is located, and they are mutually perpendicular to the projections-grooves located on the larger platform, which ensures stability and protection from vibration and impact effects exerted from different directions on each corner of the device to which the shock-absorbing bracket may be attached.

The corner functions as follows.

The design of the claimed bracket is such that it encloses the device corner on all sides (Fig. 4), allowing it to be secured to both the body and the lid of the device, allowing for additional pressing force of the lid to the body due to the elastic properties of the polymer body of bracket 1. The bracket can be used for a wide range of device sizes when producing series of brackets of different sizes, adjusting the overall height. The bracket can also serve as a device foot for installation on any device corner, ensuring the stability of the device corner due to the mutually perpendicular arrangement of trapezoidal grooves, which serve as the bracket feet (Fig. 5). It can be attached to transport packaging. The proposed bracket is designed to protect the device corner from damage when dropped, and to protect the device corner from damage and impacts during storage, operation, and transportation. The shape of the bracket allows it to be installed on all four edges of the device corner.

The system of fastening the corner, thanks to the projections 4.1, 4.2 in the pressed metal insert and the groove 3.1 on the inner side of the trapezoidal platform of a smaller size (upper) 2 for fixing on the corner of the device body, allows, if necessary, not to install fastening threaded elements, fixing only the projections and recesses of the corner on the device body, while maintaining a tight fit of the corner to the walls and fixation with the device body.

Thus, the shock-absorbing corner has mutually perpendicular protrusions and grooves in a trapezoidal cross-section, designed to protect the corner of the device if it falls onto any edge or surface. The elastic properties of the polymer prevent the housing from bending.

The technical result is to ensure universal protection of the corner of the device body.
