RU184438U9 - Leg support for workstations of PC users - Google Patents

Abstract

The footrest for the workstations of users of personal electronic computers consists of a rectangular platform for the feet made of sheet metal, with an edge bent down to the right and left, forming 90 ° bends on the sides, in which holes are made on one side and on the opposite side are elongated grooves. The other two sides of the foot platform have smaller bends upwards, also at an angle of 90 ° to the platform, the front of which acts as a stopper to prevent the feet from slipping off the platform. For the same purpose, an anti-slip coating is glued on the front side of the foot support platform over the entire area. Two supports made of metal of greater thickness are attached to the side bends of the platform on the right and left. The supports to the platform are fastened with fixing screws, the handle of which is a star-shaped handwheel that rotates directly with your hands, without the use of an additional tool. The right and left supports are the same. The front edge of the support has five holes made vertically. From the opposite edge there is a vertical cutout with five recesses made in it, similar to combs located in the same plane as the holes. Thanks to the holes on the front of the support and the cutout with recesses on the opposite side, several positions of adjusting the height and angle of inclination of the foot support platform are achieved. Two holes are made in the lower part of both supports, through which they are connected to each other by metal ties, which give additional rigidity to the entire structure of the stand. Couplers are attached to the supports with screws. The lower edge of both supports, resting on the floor, has anti-slip pads made of rubber, preventing the entire structure from sliding across the floor.

Description

Application area

The invention relates to a device designed for indoor use in equipping workstations of PC users, namely, a footrest.

The footrest is a useful and necessary device in the workplace of the user of a personal computer (personal electronic computers).

Known analogues

The closest analogue of the claimed device is a footrest, known from an electronic source of information (http://www.office-code.ru/wa-data/public/site/2015/Instrukziya%20AYAK%202015.pdf). This footrest has the ability to adjust the height and angle of the base platform from 0 to 20 degrees, which requires the use of an additional hand tool and some skills when handling it. The image of the stand is illustrated in Figure 4. The weight of the stand is 3.5 kg.

Technical challenge

Development of an improved device compared to the closest analogue, design change, simplification of the entire structure, with the possibility of more convenient adjustment of the angle of inclination with the help of manual fixing screws, without the use of additional tools. Strengthening rigidity and structural strength, increasing the maximum allowable load on the support platform to 100 kg.

Technical result

The technical result is the ability to adjust the height and angle of inclination of the support platform using manual fixing screws that do not require the use of tools, which greatly facilitates the consumer using the device compared to the closest analogue. The technical result is achieved due to the original design of the supports, which are attached to the foot platform using fixing screws that rotate directly with your hands and allow you to adjust the height and angle of the support platform without requiring special tools and handling skills, namely screwdrivers and wrenches keys. Due to the increased rigidity and strength of the structure as a whole, the stand is capable of supporting up to 100 kg. and can be used, when bringing the support platform to a horizontal position, as a staircase-pedestals for appropriate purposes. The weight of the entire structure of the stand assembly is 4,300 kg, and the size of the foot pad 409 * 324 mm.

Description

The figure 1 illustrates the claimed footrest. The footrest consists of a rectangular platform for the feet, made of sheet metal, with an edge bent down to the right and left, forming bends with an angle of 90 °, in which holes are made on one side and elongated grooves on the opposite side. The other two sides of the foot platform have smaller bends upwards, also at an angle of 90 ° to the platform, the front of which acts as a stopper to prevent the feet from slipping off the platform. An anti-slip coating is glued to the surface of the foot platform, over the entire area. To the side bends of the platform, on the right and on the left, two supports are made, also made of metal, which are different-angled trapezoid, the larger side of which rests on the floor. Holes were made on one of the sides of the support, from bottom to top, with equal pitch, on the opposite side of the support a cut was made, with five recesses made in it, like combs, located in the same plane with the holes. The supports to the platform are fastened with fixing screws, the handle of which is a star-shaped handwheel that rotates directly with your hands, without the use of an additional tool. The right and left supports are the same. Thanks to the holes on one side of the support and the groove with recesses on the opposite side, with the help of fixing screws, several positions for adjusting the height and angle of inclination of the foot support platform are achieved. Two holes are made in the lower part of both supports, through which they are connected to each other by metal ties, which give additional rigidity to the entire structure of the stand. Ties are fastened to the supports with screws and nuts. The lower edge of both supports resting on the floor has anti-slip pads made of rubber, which prevent sliding on the floor.

The figure 2 illustrates the location of the footrest from the back.

The figure 3 illustrates the location of the footrest from the front.

The figure 4 illustrates the closest analogue.

In accordance with clause 10.5. SanPiN 2.2.2 / 2.4.1340-03 "Hygienic requirements for personal electronic computers and organization of work" the PC user's workplace should be equipped with a footrest having a width of the supporting surface for the feet of at least 300 mm, a depth of at least 400 mm , height adjustment up to 150 mm and the angle of inclination of the support surface of the stand up to 20 °. The surface of the stand should be grooved and have a 10 mm high edge on the front edge.

The footrest is designed for indoor use when equipping workstations of PC users in accordance with SanPiN 2.2.2 / 2.4.1340-03, and is designed for correct and comfortable position of the legs during prolonged sitting. The claimed footrest has all the required dimensions and adjustment parameters: the width of the platform for the legs - 324 mm, the depth of the platform for the legs - 409 mm. The maximum height of the supporting surface is 155 mm, the maximum angle of inclination of the foot platform is 23 °. The weight of the footrest is 4,300 kg.

The fundamental difference between the claimed footrest from the closest analogue is to improve the overall design of the device, reduce the number of prefabricated parts, a convenient mechanism for adjusting the height and angle of inclination of the support platform using hand-held fixing screws that do not require the use of tools and handling skills, which It makes it easier for the consumer to use the device compared to the nearest equivalent. Due to the increase in rigidity and structural strength, the stand is able to withstand weight up to 100 kg and can be used to bring the support platform to a horizontal position, as a pedestal for the corresponding purposes. The design is very easy to assemble and disassemble, stable on the floor and safe to use as intended.

The claimed device has been repeatedly tested in real operating conditions. All test participants agreed that the claimed product provides maximum comfort, ease of use, ease of adjustment of height and angle, without the use of additional tools, versatile use. The foot platform with a surface of corrugated anti-slip coating has a front edge with a height of at least 10 mm to prevent slipping of the legs and thereby reduce pressure on the support surface, which ultimately allows you to feel more comfortable at the workplace, reduce fatigue, maintain posture and reduce the risk of spinal diseases.
