Abstract

A spiral torsion spring intended for expanders, with two working arms which are symmetrical to each other and can differ in construction, wherein a section which is arranged either perpendicularly or parallel to the spring axis is located at the end of each arm, and a centre section which is arranged perpendicularly to the spring axis is located on the centre plane of the spring, and a parallel section intersects said plane, wherein a moment of force is applied to each arm on the centre plane of the spring, for example at the location at which the section at the end of the arm intersects with said plane, in a direction perpendicular to the spring axis, and therefore there is no moment of force rotating the spring about the centre of the spring axis. It is also possible for two springs to be interconnected by a crossbar, wherein the spring axes are parallel to each other, and each spring has a free working arm, with a section at the end which intersects a general centre plane of the springs.

Description

Twisted Torsion Spring Technical Field

The invention relates to twisted torsion springs, which are intended for use in sports simulators, such as expanders and portable sports devices, as well as other mechanisms and devices. Prior art

Currently, there are few sports devices that use a twisted torsion spring as a resistance load, mainly a hand-held expander, which is most prevalent, and several devices, which are mostly private in nature, without widespread use.

Twisted torsion spring has good characteristics

resistance and a large number of repetitions.

The main obstacle for using torsion springs is the presence of a moment of force which, during the compression of the working arms of the spring, turns the spring around the center of its axis, in the direction perpendicular to the axis of the spring.

In some sports devices, this moment of force

eliminate with the help of the location of the spring on the shafts or axles, as well as using various devices.

Known sports devices that eliminate this moment of force, due to the geometric shape of the working arms of the spring, but they are not widely used, and did not become the basis for the design of other types of expanders.

The main obstacle is the lack of determination of the position of the working arms, specifically the place of application of force on each arm, relative to the spring itself.

Known simulator, patent JP 2005152077 (A), consisting of a twisted torsion spring with two working shoulders, which at the end there are areas parallel to the axis of the spring and are the stops for the forearms. Despite the successful design, the place of application of forces on the stops is uncertain, which causes a moment of force that unfolds the spring around the center of its axis.

Known simulator, patent US 4483533 (A), consisting of

twisted torsion spring, two working shoulders, which are located with the help of bends perpendicular to the axis of the spring, and leg ends are located at the ends of the shoulders. The arrangement of the shoulders and the stops is the most successful, but in the invention only structural elements are described and there is no definition of the location of the stops in space relative to the spring, which allows the device to be made with the necessary

result, only with the help of drawings, but does not allow

use a good solution in other sports devices.

DISCLOSURE OF INVENTION

The objective of the invention is to create a twisted torsion spring with working shoulders, which, without additional devices and

devices, when a load is applied to her shoulders,

the direction perpendicular to the axis of the spring, there is no moment of force turning the spring around the center of its axis.

The problem is solved for the fact that the twisted spring

torsion at the end of each working arm has a straight section located perpendicular to the spring axis, and symmetrically to the section on the other shoulder, and located on the center plane of the spring, this section being the point of application of the torque, in the direction perpendicular to the spring axis, resulting in

the directions of the moments of forces are on the same plane and

there is no unfolding of the spring around its axis.

The same spring may have a section at the end of each arm.

located parallel to the axis of the spring and intersecting the average plane of the spring, in which the intersection of the section with this plane is the place of application of force.

The location of the sections on each shoulder is formed by means of bends, symmetrically to the bends on the other shoulder, while

each shoulder can have an additional angle, symmetrically

corner on the other shoulder, and which is formed by bending.

Similarly, the shoulders of the arms, at any location of the plots at their ends, can interbreed with each other, and have at each

shoulder two opposite corners, symmetrically to the corners on

the other shoulder, and the opposite corners are located before and after crossing, and are formed with the help of bends.

When the areas at the ends of the shoulders are parallel to the axis

the springs, the bends forming their position can be located both on one side of the spring's mean plane and on different sides of this plane.

In this case, the springs having at the end of each shoulder area

parallel to the axis of the spring, with an angle on the shoulder, can be performed with an additional section located either perpendicularly or parallel to the axis of the spring, and which can be either at the site of the vertex of the corner, either before or after it, and the plot is located only parallel to the axis of the spring and is located either in place of the top of the second corner, from the spring, or to the top of the corner.

It also offers a variant with two torsion springs, in which the axes are parallel to each other, and the springs have a common median plane, and the shoulder of one spring is connected to the shoulder of the other spring with a crossbar, while the free shoulder of each spring has a section parallel to the spring axis at the end, and Crosses the common median plane of the springs, and between the spring and this section at the end of each arm is another section located either perpendicularly or parallel to the axis of each spring.

Also in the version with two springs, the free arms of the arms can either be located between the springs or from the outer sides of the springs.

In all variants, all sections and angles on the shoulders of the springs are formed by means of bends, while except for the main bends, all

variants may have additional bends on each shoulder, for example, after a section located parallel to the spring axis, or spring axis, at the end of the shoulder, and which is symmetrical to the bend on the other shoulder.

Industrial Applicability

The presented versions, with any configuration of the spring arms, ensure the absence of a moment of force, which turns the spring around the center of its axis, in the direction perpendicular to the axis of the spring, when the place of application of force is on the center plane of the spring, which allows

use a torsion spring in various ways

Moreover, the correct determination of the application of the moment of force to the shoulders of the spring allows you to create variants with two

springs connected to each other.

Known industrial technologies allow you to create

different configurations of the spring, with any bends on their shoulders, which greatly simplifies the manufacture of various types of expanders, and the correct determination of the place of application of force allows you to significantly simplify the design of expanders, for example, without additional accessories and devices.
