In country houses, it is not easy to place a convenient staircase for climbing into the attic. And, it turns out, there is a way out. It is in the use of the well-known design of the parallelogram mechanism, which is sometimes used to fix wall lamps. Only in our case, we need two such devices connected by crossbars. It is convenient to use wooden rolling pins as crossbars. Holes are drilled in their ends, where threaded metal rods are inserted on the glue. The ends are reinforced with thin aluminum rings. The pitch of the steps is selected so that it would be convenient to climb the stairs for both large and small.

The upper crossbar is mounted on two steel angle brackets, which are fastened with large screws to the wall under the hatch leading to the attic.

On the ends of the rods protruding from the brackets, short links of the parallelogram mechanism are put on, made in the same way as the long links, from an aluminum strip with a thickness of at least 5 mm. Through holes are drilled in them to facilitate; strength does not suffer from this. The links are alternately put on the axis of the crossbars, then the ganks are screwed on. Between themselves, the links are connected pivotally with bolts or rivets.

Ladder in the summer house
Folding ladder (click to enlarge): 1 - crossbeam, 2 - aluminum ring, 3 - bracket, 4 - inner short link, 5 - outer short link, 6 - rod-axle, 7 - long links, 8 - hooks for "ladder" "in the retracted position, 9 - shoes.

The folded structure is hung on hooks pre-driven into the ceiling. In the "straightened" position, our home ladder rests on two small shoes nailed to the floor.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Scientists have implanted a chip in the brain 24.07.2017

American scientists have implanted a microchip in the brain to restore vision lost by a person. A new development called FlatScope affects certain areas of the brain and helps the blind to see.

The device controls and fires the neurons that are responsible for receiving visual information.

This invention is part of the DARPA project, an initiative dedicated to the creation of a neural interface to help solve various health problems.

Experts expect that with the help of chips it will be possible to restore not only vision, but also hearing.
