This application claims priority of Russian Patent Application RU 2021106534 filed Mar. 13, 2021 the disclosure of which is hereby incorporated by reference in its entirety.
The invention relates to the field of satisfying human needs and specifically relates to a shoe horn or a structure of a device for putting on footwear.
There is a known a model of a shoe horn that consists of a handle in its upper part and a blade in its lower part. Shoe horns of very different shapes and sizes, long or short, made of steel and plastic, consisting of a grip and a blade, are known.
The technical solution known to the applicants and that resembles the claimed one is an elongated shoe horn (CA2167950 dd. 1997 Jul. 25) consisting of an elongated piece that has a narrower upper part and a wider lower part, and has a hook-type configuration in its narrower upper part. The shortcoming of this technical solution is its narrow scope of application, uncomfortable use, namely the difficulty of holding it in hands of a user.
It is the task of the invention to engineer a dual-purpose shoe horn—a shoe horn and a weapon usable in close combat—the solution to which the claimed invention attempts to carry out.
This task is accomplished by the fact that the shoe horn for putting on footwear consists of a blade in the form of a trapezoid rod with a longitudinal groove along its entire length, a guard mounted on the blade using the press fitting method, a grip shaped as a steel tube and press fitted on the narrowed part of the blade and touching the guard, a wedge with a pommel press fitted into the tube of the grip.
The technical result ensured by the listed sum total of the features manifests itself in making the shoe horn balanced in the area of the guard.
The essence of the invention is illustrated by the drawings wherein:
The shoe horn for putting on footwear consists of the following essential units: the blade 1, the guard 2, the grip tube 3, the wedge 4 and the pommel 5. The blade 1 is a trapezoid-shaped rod with a longitudinal groove along its entire length.
The guard 2 has a rounded shape and formed with circular holes of varying diameter along the edge of the circumference. Such position of the holes ensures the most authentic outlook and resembles the Japanese style of weapon design.
The grip tube 3 is a rounded steel tube.
The wedge 4 is a truncated cone with extension bar 6 with a threaded connection at the end. The extension bar 6 is designed to be cylindrical in shape, By selecting the thickness of the extension bar (diameter) the needed balancing adjustment of the whole device is achieved.
The pommel 5 has a complex geometrical semi-spherical shape with a threaded inner part.
The central unit that holds the whole shoe horn together is the blade 1. The guard 2 is mounted on the narrower side of the blade 1 by means of the press fitting method. The grip tube 3 that touches the guard 2 is also press fitted on the narrower part of the blade. The wedge 4 is screwed into the pommel 5 by means of a threaded connection on the extension bar 6. At the next stage, the wedge 4 with the extension bar and the pommel 5—as a whole unit—is press fitted into the grip tube.
In the process of press fitting the wedge 4, the maximum diameter of the wedge cone is coupled with the narrower end of the blade 1 and, due to the addition of the thicknesses of the parts, the grip/handle tube 3 expands to ensure maximum traction of all the components of the shoe horn.
The blade of the shoe horn has an elongated design which makes the shoe horn of the invention user-friendly, especially for elderly people or people who bend with difficulty. The fact that the shoe horn has a balanced design also allows it to be held in the hand in a steady fashion and with ease.
The shoe horn has a perfectly balanced design which allows it to be used as sports equipment in fencing sports.
The grip of the shoe horn may be wrapped in various decorative materials such as straps, velvet, or leather.
The pommel may be complimented with engravings, or medallions made of various materials and metals. The blade can also be complimented with engravings produced by various methods of engraving.
The blade is made of stainless steel. The guard is made of stainless steel. The grip tube is made of chrome-plated steel. The wedge is made of type 35 steel. The pommel is made of D16T alloy.
The shoe hone has the balancing point in the area of the guard which allows one to use the shoe horn as sports equipment in fencing practice as well. The balance distribution of the shoe horn is achieved by means of the geometry of the wedge and the pommel which ensure correct distribution of the weight characteristics of said parts inside the grip tube. The steel wedge has a geometry which combines the length and the thickness to obtain a specific weight which, together with the weight of the duralumin pommel, ensures the balancing point of the complete piece to be located in the area of the guard. The shoe horn has therefore two lever arms, one arm being the grip with the pommel, the other arm being the blade, and the two arms are balanced in the area of the guard.
Preferable dimensions of the parts of the device:
The claimed technical solution of the invention has therefore the following competitive advantages:
