Features of glider chairs, advantages, disadvantages

Furniture has long ceased to be an ordinary household item; people expect an increased level of comfort and maximum functionality from it. One of these products is a glider chair, which provides a high level of comfort and will delight you with its practicality. Manufacturers present a variety of models, colors and additional elements: pockets, wide armrests, leg straps and so on. Each piece of furniture is equipped with a beacon mechanism, which allows you to transform it from a regular chair into a movable one.

Design Features

Gliders appeared on the market not so long ago, but they managed to fall in love with consumers. Externally, they are practically no different from ordinary rocking chairs. To have a complete understanding of what a Glider chair is, it is worth considering the design features and familiarizing yourself with the original solutions offered by manufacturers. Main characteristics of the product:

1. There is a beacon mechanism that provides easy rocking. It works absolutely silently.
2. There is a foot rest, which allows you to sit more comfortably in the chair.
3. The variable angle of inclination makes it possible to adjust the product to each person. Reliable fixation of the selected position is provided.
4. Clear and comfortable control: electrical, mechanical or touch.
5. Convenient adjustment: you can fix the desired position by simply touching the backrest, lifting the lever or pressing the corresponding button on the remote control.
6. Varieties of footrests: pouf, ledge or retractable structure. The last option is equipped, for example, with the Glider Rydberg chair model.
7. Availability of additional functions: massage, aromatherapy, heating.

Each model has detailed characteristics and instructions for use. The chair can be used by all family members. Nursing mothers especially love to sit on it. An acceptable price combined with high quality, functionality and increased comfort makes chairs of this type in demand despite the fact that the product has appeared on the market relatively recently.

Main types

Before choosing where to buy a glider chair, you need to find out what types of this piece of furniture there are. There are several classifications that allow you to divide all models into several groups with similar characteristics.

Popular types:

1. Classic. Models of this type are popular and often purchased. They have a simple design and are relatively inexpensive. Such products are equipped with a special retractable footrest, made in the form of a small pouf. Thanks to this design feature, classic glider chairs are compact and suitable for use in small spaces.
2. Foldable. This type of furniture is the most versatile, as it is suitable for relaxing children and adults. It has a folding design that vaguely resembles a chaise lounge. It does not have retractable footrests or other additional elements. In most cases, folding models are compact in size and have a reasonable price.
3. Massage. This piece of furniture is an improved copy of the classic glider chair, complemented by massage elements. In addition, it is equipped with a transformation mechanism that allows the product to be used by people of different heights. Such chairs are expensive, so only people with great financial resources can afford to buy them.
4. Advertiser. Models of this type guarantee the user the maximum level of comfort. They have an anatomical shape of the seat and back, which reduces the maximum load on the spine and joints. Such products are classified as premium furniture, which has a very high price.

Advantages and disadvantages

When choosing a model, you should consider the main advantages of furniture. This:

1. Convenience and safety. The rocking chairs are equipped with armrests, footrests, and some have a sliding footrest.
2. The beacon system ensures smooth movements and does not damage floor coverings.

Glider chair – what is it?

The glider system consists of a conditionally fixed base and a seat, which are connected to each other using two pairs of pendulum-type suspensions. The suspension allows the chair to sway like a swing, and the length of the hinges limits the amplitude of the oscillations.

The birthplace of glider chairs is the United States. At the beginning of the 20th century, Americans were presented with the first such products, equipped with a variety of swing devices. Only in 1939 did the first pendulum chair appear. It acquired the form in which we are accustomed to seeing it not so long ago.

Modern models of glider chairs are equipped with a pendulum device and a separate bench, also equipped with a pendulum-type mechanism. Usually they are bought by young mothers, since sitting in them, you can easily and quickly rock newborns to sleep.

Manufacturing materials

Various materials are used in production, and all of them are of high quality. The frames are distinguished by their strength, durability, and wear resistance due to steel or aluminum arches framed by durable wood. They are made from the following materials:

1. Natural wood. Durable material that can withstand significant loads. The wood has a beautiful structure, lends itself well to processing and cutting, so it is very popular among manufacturers.
2. Lightweight plywood. The characteristics are not inferior to wood, but have a lower price. Only thick sheets are used for production.
3. Metal. Durable and very flexible material. It is not used often, since during operation, elements made from it can creak.
4. Chipboard. Resistant to moisture, withstands loads well. Disadvantage: it contains harmful resins.

The upholstery of the seats is made in different colors. Popular manufacturing materials:

1. Genuine leather is durable and presentable.
2. Chenille - characterized by an elegant appearance and high wear resistance.
3. Velor is a soft and durable material.
4. The tapestry is natural and has anti-allergenic properties.
5. Jacquard is budget-friendly and durable.
6. Matting is eco-friendly, stylish, dense.
7. Flock is wear-resistant and durable.
8. Artificial leather is durable, hypoallergenic, not afraid of the sun, and has a presentable appearance.
9. Eco-leather is practical and has a wide variety of textures.

The products are filled with foam rubber or polypropylene, which provide the required softness and comfort.

Underwater glider "Sea Shadow". Tool for the Navy and for Science

At the beginning of February, new reports appeared in the domestic media about the promising underwater glider “Sea Shadow”. The special apparatus has a special architecture and uses unusual principles of movement, which gives it noticeable advantages over other types of equipment. This time the glider is proposed to be used as a means of studying the seas and oceans. Necessary o is not new. The first sample of this glider was shown a few years ago, and since then prototypes have regularly appeared at exhibitions and also been tested.

For the first time, the promising project, unnamed at that time, was told to the public in 2016 as part of the Army forum. At that time, the work continued for several years and managed to lead to the appearance of the first prototypes. Demonstration tests of the new model soon took place. Subsequently, the glider, receiving the name “Sea Shadow,” took part in new exhibitions and continues to undergo the necessary tests.

The development of the new glider was carried out by several organizations. The main developers are the St. Petersburg State Marine Technical University (SPbSMTU) and the scientific and production enterprise of underwater technologies "Okeanos". Other organizations were involved in the research. The project is being implemented with the support and supervision of the Main Research and Testing Center for Robotics of the Ministry of Defense.

The glider project started in 2011 and was developed on an initiative basis, but soon received government support. In 2012, the first prototype was built at St. Petersburg State Medical University, implementing special principles of movement and capable of diving to a depth of 100 m. In 2014, the next stage of research was completed, as a result of which a new full-size prototype appeared. Since 2015, it has been passing all necessary tests. Various studies and tests are still ongoing and provide the required results.

In 2016, the glider, at that time unnamed, was shown to the public for the first time. At the same time, they talked about plans to create a complex that would include several underwater vehicles for various purposes. Later there was a demonstration of the new product. Since 2017, the glider has been featured in exhibitions and publications under the modern name “Sea Shadow”.

***

In its current form, the Sea Shadow product is an underwater vehicle that resembles a torpedo with a set of planes. The glider is built in a cylindrical body with a head and aft fairing. There are wing planes on the sides of the hull, there is also a vertical plane and several other protruding elements. For greater convenience for testers, some prototypes are built in a transparent case. Glider length – 3 m, body diameter – 310 mm, weight – 150 kg.

The energy system of the device is based on a rechargeable battery. In the first tests, a lithium-ion battery with a capacity of 70 Ah was used. The possibility of using other current sources, including more efficient ones, was also mentioned. The glider does not have the usual propulsion system and propulsion system. The essence of the project is movement using hydrodynamic forces. In this case, ballast tanks and their control systems are responsible for the movement of the apparatus.

Taking on water, the glider loses buoyancy and tends to sink to depth. The presence of several controllable tanks allows you to change not only buoyancy, but also trim. When buoyancy decreases, the lateral planes do not allow the device to descend vertically and force it to “plane” in the water. By sequentially taking in and removing water from the tanks, the underwater vehicle navigates. Due to the specific operating principle, its trajectory in the vertical plane resembles a sinusoid.

The absence of a conventional propulsion system limits the maximum speed of the glider to 1-2 knots. At the same time, the drives of ballast tanks, in contrast to the propulsion engine, use battery power more economically. Due to this, the device is able to continue working without recharging for a long time. So, for the “Sea Shadow” in its current form, the battery life is determined at 8 months.

The hydrodynamic principle of movement limits speed and also imposes restrictions on maneuverability and seaworthiness. To get rid of these problems, in 2022, St. Petersburg State Medical University and Okeanos introduced the so-called. hybrid propulsion system. It retains controllable ballast tanks, but they are supplemented with a conventional propulsion engine and propulsion system. Most of the time, the hybrid installation must use the hydrodynamic principle of movement, and the propulsion motor is designed for occasional maneuvering, overcoming currents, etc.

On board the glider there is a set of sensors that determine its position in space and other parameters. On-board automation with original software analyzes incoming data and makes the necessary decisions. In particular, a self-navigation mode is provided: based on current conditions, the autopilot itself calculates the parameters of the trajectory and controls the device.

***

“Sea Shadow” in its current form, having a mass of 150 kg, is capable of carrying on board up to 15 kg of payload. The glider can be equipped with various types of special equipment. It is also capable of becoming a carrier of light underwater vehicles. Initially, the project developers mentioned the possibility of using the glider in military affairs. The device can search for enemy submarines and ships or solve other problems. Recent reports mention the possibility of using the technology in scientific projects.

Hydroacoustic stations of various types, including those using a towed antenna, are proposed as the main payload. It is also possible to use other search equipment for military or scientific purposes. In the latter case, “Sea Shadow” can monitor the situation, conduct oceanographic research and even carry out oil exploration. In all cases, along with such devices, the glider must carry communication equipment to transmit data about the underwater situation and detected targets.

Development organizations offer the sharing of several gliders as part of a common “flock”. In this case, a group of vehicles must be launched into a given area using a surface or underwater carrier vessel, which will also be responsible for data collection, control, etc. As with the use of single gliders, the “flock” will be able to solve military and civilian problems. The group use of underwater vehicles with a surface carrier, including an autonomous one, will increase the operating time. The “flock” will be able to stay in a given area for up to a year.

At the Army-2017 exhibition, a version of the complex was presented, including several variants of the “Sea Shadow” with different tasks. The complex includes a glider with special equipment, a glider-carrier for small-sized underwater vehicles, a device with a radio signal repeater and a surface control post. Thus, the “flock” can not only solve a common problem, but also distribute roles between several devices.

***

During the latest military-technical exhibitions, St. Petersburg State Medical University and NPP PT "Okeanos" repeatedly showed their developments in the field of underwater gliders. This equipment was demonstrated to representatives of the military department, including the Navy command, and it received high marks. Currently, the Sea Shadow project is being implemented with the support of the Ministry of Defense, and the navy is showing interest in such equipment.

However, there has not yet been any news about the adoption of gliders by the Russian Navy. There are also no reports of real interest in this technique from research organizations. The project remains at the testing and development stage. It is unknown when the “Sea Shadow” will reach real exploitation in the interests of the military or scientists.

***

In its proposed form, the “Sea Shadow” product is of great interest from a technical point of view. The concept of an underwater glider that moves by changing buoyancy and balancing has been known for a long time and is used in foreign projects. Similar samples are being developed in our country, and domestic products are superior to foreign ones in some characteristics and capabilities.

The advantages of gliders are obvious. These include efficiency, providing greater autonomy and range, minimal noise, the ability to use a modular payload and, therefore, the ability to solve a wide range of tasks. Due to proper design of the complex, it is also possible to reduce operating costs. The glider should not require a separate specialized support vessel; the necessary instruments should be placed on any surface carrier.

At the same time, gliders are not without their drawbacks. The low speed of movement limits mobility and does not allow quickly transferring equipment from one area to another. The movement follows a characteristic complex trajectory, which should be taken into account when planning the route. Dimensions and payload limits the payload and negatively affects its efficiency. Finally, there is no experience yet in the widespread use of gliders in all areas, which requires a fairly long period of development and development.

Potential customers still have to weigh the pros and cons of the underwater glider concept itself, and then evaluate the characteristics and capabilities of specific samples - such as various modifications of the Sea Shadow apparatus from St. Petersburg State Medical University and NAA PT Okeanos. This project is being implemented with the support of the Ministry of Defense, which may indicate the interest of the fleet both in a specific development and in the entire class as a whole.

According to recent reports, the promising underwater glider “Sea Shadow” is capable of solving not only military, but also scientific problems. Thus, a domestic model can find several customers at once and begin work in several areas. However, the timing of the start of serial production and service in the Navy or in scientific organizations remains unknown.
