Portable Folding Swing

Abstract

Portable folding swing is being made of 3 basic parts 1a and 1b mutually connected with hinges (2) enabling folding (illustrations 3 and 4). The body (3) of swing frame is also separately foldable part that can be placed into double flexible joints (8) and (9) located on the body 1a (illustrations 1 and 2). Body (3) can be upwardly removed with the axle (10) from the body 1a and separately folded as shown by illustration 5. The swing can be used on the move due to wheels (5) located on at the front of the body 1a (illustration) and is a children's toy.

Description

DESCRIPTION OF THE INVENTION

1. Technical Field

This invention belongs to the category of children's toys, with the following characteristics:

• • two larger wheels that enable use of swing on the move
  • it can be folded for easier transport.

2. Technical Problem

Technical issue this invention solves is how to make a walk more interesting to child than standard trolley, with the child swinging during the walk, having fun. Coming to a bench, child's parents may rest with the child still swinging. The swing has legs so it can stand on its own.

3. State of the Art

The author is unaware of any similar all-terrain swing which retains its swing capabilities. Browsing all accessible sources of information (Internet, magazines, fairs, shopping malls) he didn't come across any technical solution.

EXPLANATION OF THE NATURE OF THE INVENTION AND DESCRIPTION

Portable folding swing is based on two new technical solutions:

• • Mobility due to two front wheels
  • Foldability which enables the swing to be placed in the trunk of even small cars.

The swing is made out of three basic bodies—1a and 1b—connected with hinges (2) that enable folding and assembly of the swing (illustration 3). The body (3) containing swing basket 4a is made out of lower seat of the swing 4b and flexible spacers 4c (illustration1). The body 1b has swing legs (6) that can be tightened with the screw (11) and rotated around the body 1b into position illustrated on 3 and 4. On the body 1a made out of curved pipe ø 1″ with thin wall, at the front of the body 1a are wheels (5) that can be rotated with frame (7) tightened with the screw (12). Due to its cylindrical shape, it can be moved along the body 1a in order to put wheels into wanted position more easily (5) (illustration 4) and enable regulation of swing's center of gravity along the body 1a. The body of swing (3) is made out of 4 frames (3) that are connected with an axle (10) (illustration 2) with rotating frame (4), seats (4) carrying basket elements 4a and 4b with the string that passes through spacers 4c enabling flexibility and foldability of the basket. Swing body (3) is foldable element that is installed on the body 1a with 2 double flexible joints (8) and (9) (illustration 3). Folding of the swing body (3) is enabled by the axle (10) (illustration 5).

DISCLOSING THE ESSENCE OF THE INVENTION

The essence of the invention of a portable folding swing is that it consists of 3 basic parts 1a, 1b connected with hinges (2) (illustration1) which enable folding (illustration 3). The body (3) swing frame is also a foldable part that can be placed on 2 double flexible joints (8) and (9) that are located on the body 1a (illustration 1) and (illustration 2). Pulling the axle (10) makes the whole body (3) separate from the body 1a and fold according to the illustration 5. Another characteristic of this invention is its mobility provided by the wheels (5) on the body 1a (illustration 2).

MODE FOR CARRYING OUT THE INVENTION

Portable folding swing is primarily intended for entertainment. It can be used for walk in all terrains (city, beach, park). Thanks to large air-filled wheels it can be transported on non-paved roads. Materials standard in this branch of technology are used in commercial purposes—namely steel pipes 33 mm with thin walls and rectangular profiles 30×10 and 20×10 mm. Pipes are bent with the cold method, other parts are connected with welding. The seat can be wooden or plastic.

Claims

1. Portable folding swing, portable due to two front wheels and folding so that it can be placed in the trunk of even small cars is characterised by three bodies, 1a and 1b (illustrations 1 and 2) connected with double hinges (2) enabling them to be folded (illustrations 3 and 4), front wheels (5) on body 1a enabling mobility and swinging on the move, while the legs (6) on body 1b enable swinging in place (illustration 1). Body (3) is a separate whole that is connected to the body 1a via two double joints (8) and (9), and can be separated from the body 1a and folded into a separate whole (illustration 5) which makes the construction more suitable for storage in the trunk or household store.
