Description

The utility model relates to seating equipment, namely hanging chairs, and can be used as a piece of furniture for leisure, entertainment, and relaxation.

Recently, hanging chairs made of tubular elements have become increasingly widespread, consisting of a support in the form of a curved post mounted on a support element and a seat that is suspended from the top of the support, resembling a hemisphere in shape (patents US 10631647 B1 from 04/28/2020, CA 3021852 dated 08/18/2020, US D963361 S dated 09/13/2022, US 11540636 B1 dated 01/03/2023, US 10912386 B2 dated 02/09/2021). These chairs have proven themselves well in use and fit well into any interior.

The pricing of chairs depends, among other things, on the volume they occupy during transportation, in particular, the larger the volume of the product, the more expensive its transportation costs, and therefore, the more expensive the final price of the product. In this regard, manufacturers have to find ways to reduce the volume of the product.

To solve this problem, manufacturers resort to prefabricated chair structures, in which the stand and seating area are connected by fastening connecting elements (RF utility model patent 218596 dated 02/14/2023). Said hanging rocking chair contains a stand mounted on a support, a body suspended from the top of the stand, made in the form of a frame, and fabric covering. The body of the rocking chair is made of tubular elements, and each tubular element of the body is bent in such a way that when assembled it forms the shape of a truncated hemisphere, the edges of each tubular element are flattened and contain holes for a fastening element that rigidly connects them to each other in the upper and lower parts, and in the lower part of the body, on top of the two outer tubular elements, there is a tightening element, and the stand is made detachable.

The disadvantage of this chair is that the body itself has rigidly fastened tubular elements, therefore, it will take up quite a lot of space.

From the prior art, chair bodies with a prefabricated structure that allows them to be folded during transportation are also known (patent DE202022102422U1 dated July 28, 2022). The patent presents a hanging chair in which the body is divided into upper and lower parts, and they are folded together thanks to a semicircular connecting element and a hinged fastening.

The disadvantage of this invention is the difficulty of assembling and disassembling the chair, since each tubular element must be secured with at least two fasteners on both sides.

The closest to the proposed utility model in terms of technical essence and achieved result (prototype) is a folding hanging basket containing an annular front frame and a support pipe assembly, the connecting elements are located at the upper and lower ends of the front frame, the upper and lower ends of the support pipe assembly are respectively connected to an upper connecting element and a lower connecting element, wherein the annular front frame is made detachable and consists of two parts, the upper and lower connecting elements are made in the form of upper and lower folding mechanisms, each of which consists of two brackets hingedly connected to each other, and the edges each bracket is permanently connected to each other to form an open right angle, the support pipes and two parts of the detachable annular front frame are made with the ability to fold towards the center (inward) of the device (RF utility model patent 219154 dated 05/31/2023).

This design needs to be improved, since analysis has shown that it is possible to simplify the design by eliminating many fasteners and threaded connections, while reducing the dimensions of the folded basket.

The proposed utility model solves the problem of reducing the labor intensity of transportation and assembly of the device, and also ensures an increase in the compactness of the chair design.

The problem is solved by the fact that the chair frame is made of six tubular elements, where three tubular elements on the right and left are hinged to each other and fastened with internal connecting plates at the top and bottom. In this case, the outer tubular elements, forming an annular front frame, are bent inward at the upper and lower edges of the chair before connecting with the inner tubular elements, and the inner tubular elements are made in the form of a truncated semicircle. Giving the structure a stationary state is achieved by fastening the outer tubular elements with outer connecting plates.

The reduction in the labor intensity of transportation is due to the increased compactness of the utility model, achieved by making the outer tubular elements curved before connecting with the inner tubular elements, and the inner tubular elements in the form of a truncated semicircle, thereby making it possible to reduce the size of the arc of the folded chair, equal to the size of the arc of the internal tubular elements (Fig. . 4).

The ease of assembly of the device is due to the absence of an excessive number of connecting units and fasteners, compared to the prototype, and the need to secure only one bolted connection on the outer connecting plate at the stage of delivery to the consumer.

The utility model is illustrated by the following drawings:

in fig. 1 shows a general view of a folding hanging chair in an open state;

in fig. 2 shows view A (remote view of the upper folding mechanism);

in fig. 3 shows view B (external view of the lower folding mechanism);

in fig. Figure 4 shows a general view of the folding hanging chair when folded

The operation of the utility model is illustrated in Fig. 1, fig. 2, fig. 3 which are marked:

1 – right outer tubular element;

2 – left outer tubular element;

3a, 3b – left internal tubular elements;

4a, 4b – right internal tubular elements;

5 – upper outer connecting plate;

6 – lower outer connecting plate;

7 – internal plates;

8 – swivel joint;

9 – fastening elements.

The chair consists of six tubular elements. The right outer tubular element 1 and the left outer tubular element 2 are made of a pipe with a circular cross-section, represent an outer annular frame, and are rounded inward at the upper and lower edges of the chair before connecting with the internal tubular elements, and also have mounting holes at the junction with internal tubular elements for subsequent hinge connection, as well as two holes for connection to the outer connecting plate. The left and right internal tubular elements 3a, 3b, 4a, 4b are also made of pipes, made in the shape of a truncated semicircle and flattened at both ends, in the flattened places there are holes for a hinge connection.

The upper connecting plate 5 and the lower connecting plate 6 are long arc-shaped pieces with rounded edges made of sheet material with two holes at the edges for fastening the outer tubular elements together. The upper connecting plate 5 has a hole in the middle, which will be used for hanging the chair. The inner plates 7 are short plates made of sheet material with two holes for fastening the right tubular elements and the left tubular elements to each other.

The right outer tubular element 1 is hingedly connected to two right inner tubular elements 4a and 4b, so that the outer tubular element 1 is located in the middle, and directly above and below it on both sides there are internal connecting plates 7, then on the connecting plates 7 are installed internal tubular elements, with the internal tubular element 4a located above the right outer tubular element 1, and the internal tubular element 4b located under the right outer tubular element 1. The hinge connection 8 is created by aligning the holes in the specified parts and fasteners.

The left outer tubular element 2 is hingedly connected to the two left inner tubular elements 3a and 3b, so that the outer tubular element 2 is located in the middle, and directly above and below it on both sides there are internal connecting plates 7, then on the connecting plates 7 are installed internal tubular elements, with the internal tubular element 3a located above the left outer tubular element 2, and the internal tubular element 3b located under the left outer tubular element 2. The hinge connection 8 is created by aligning the holes in the specified parts and fasteners.

Thus, the right and left tubular elements are assembled separately, and the connecting plates 7 used act as a connecting element between the two hinge joints, and allow the function of rotating the tubular elements of the chair from 0 to 180 degrees.

Next, to fix the chair and give the structure a fixed position, the upper outer connecting plate 5 and the lower connecting plate 6 are used, in particular, the outer tubular elements 1, 2 and the outer connecting plates 5 and 6 are closed with their edges, after which they are secured with fasteners 9 in two places.

It should be noted that to fold the hanging chair (Fig. 4), it is enough to disconnect one fastening element on the upper connecting plate 5 and the lower connecting plate 6, since the hinge joints 7 allow the rotation function from 0 to 180 degrees.

The chair arrives to the consumer folded, shown in Fig. 4.

With the help of a little effort from the person assembling the folding hanging chair, the arcs of the tubular elements move apart to form a semicircle (Fig. 1). When folded, the size of the chair's arc will be equal to the size of the arc of the internal tubular elements 3a, 3b, 4a, 4b.

Inside, the frame between the tubular elements is braided with durable plastic material, such as rattan. The finished structure is suspended from the hole in the outer upper connecting plate to the vertical post using an s-shaped hook.

Thus, the proposed design of a folding hanging chair will make it possible to give a compact size to the product, facilitate transportation and assembly of the product due to the configuration of tubular elements: external tubular elements rounded inward before connecting with the internal tubular elements and internal tubular elements made in the form of a truncated semicircle, as well as the presence of two hinged joints of tubular elements, fastened together by internal connecting plates and two external connecting plates, allowing the outer tubular elements to be fixed.
