JPH0284993A - Covering part for electric sewing machine - Google Patents

Abstract

PURPOSE:To use an electric sewing machine in a place, where a commercial power source is hardly obtained, by arranging plural solar batteries to a part of an external surface in a covering part, connecting an edge part to the solar battery, building a cord, whose one edge can be led out, in the covering part and electrically connecting one edge of the cord to a sewing machine and the covering part. CONSTITUTION:The sewing machine is transported to a camping place by a camping car 9 and a cord 6 of a covering part 2 is led out and connected to a sewing machine 1. Then, the covering part 1 is set in the open air so as to be radiated with a sunlight S and the sewing machine 1 is set in the camping car 9 or under a tree. Thus, the sewing machine 1 can be electrically driven by activation force generated in solar batteries 3 in the covering part 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a covering part for a sewing machine that is connected to an electric sewing machine equipped with an electric drive unit and equipped with a power source for the drive unit of the electric sewing machine.

(Prior art) The conventional technology is to either drive the sewing machine by transmitting rotation to the pulley of the sewing machine by means of a treadle motion via a belt, or to drive the sewing machine by connecting an electric motor built into the sewing machine to a commercial power source. He operated a sewing machine, but the former was large and inconvenient to move around, and the latter had the disadvantage that it could only be used in areas where commercial power was available.

(Problems to be Solved by the Invention) The present invention is miniaturized for easy portability and can be used in places where commercial power is difficult to obtain, such as outdoor camping sites where people stay for several days or more. be.

(Means for Solving the Problems) The present invention electrically connects to an electric sewing machine equipped with an electric drive unit a covering part that can be easily removed and covers the electric sewing machine, and exposes the outer surface of the covering part to sunlight. By arranging multiple solar cells that absorb the energy of photons and generate electromotive force when exposed to light, the device becomes smaller and easier to carry to outdoor camping sites where commercial power is not available, and can also be used at outdoor camping sites. This is what I did.

(Function) When using the sewing machine, the covering part that covers the sewing machine when carried is removed from the sewing machine, and the covering part is placed in the open air exposed to direct sunlight, and the covering part and the sewing machine are electrically connected with a connecting cord. The present invention is characterized in that the sewing machine drive section is energized to operate the sewing machine by obtaining an electromotive force generated in a plurality of solar cells arranged on the outer surface of the cover part.

(Embodiment) An embodiment of the present invention will be described below. Reference numeral 1 denotes a sewing machine, and the sewing machine is provided with an electric drive section (not shown), and the sewing machine is activated by energizing the electric drive section. Forced to drive.

Reference numeral 2 denotes a covering part which is removed when the sewing machine 1 is not in use or when used for praying.

A plurality of solar cells 3 that absorb photon energy and generate an electromotive force when sunlight hits a portion of the entire outer surface of the covering portion 2.
A reel 4 is built into the covering part 2 and is returned to its original position by a spring (not shown).The reel is provided with a connector 5 at one end and connected to the solar cell 3 at the other end. A connecting cord 6 is wrapped around the terminal. Reference numeral 7 denotes a battery outlet, which is disposed on a part of the outer surface of the covering part 3, is connected to the solar cell 3 within the covering part, and is configured to receive a connecting end 8 of a rechargeable battery on the outside. .

Since the present invention is constructed as described above, the present invention is transported to a campsite in a camper 9, the cord 6 of the covering part 2 is pulled out and connected to the sewing machine 1, the covering part 2 is placed in an open area exposed to sunlight S, and the sewing machine is By placing the sewing machine 1 inside the camper 9 or in the shade of a tree, the sewing machine 1 can be electrically driven by the electromotive force generated in the solar cell 3 of the covering part 2. Moreover, if the terminal of the cord 6 connected to the solar cell 3 of the covering part 2 is connected to the vacuum cleaner 10, the vacuum cleaner is energized and can be electrically driven. Furthermore, if the terminal 8 of a rechargeable battery is connected to the connection terminal 7, the battery can be charged.

(Effects) Since the present invention has the above-described structure and function, if you take it outdoors where commercial power is not available, expose the covered part to the open air, and connect the cord inside the covered part to a sewing machine or other electrical equipment, the covered part can be removed. The electromotive force generated in the solar cells enables continuous operation. However, since the outer surface of the covering part can be secured in an extremely wide area in sewing machine products, it is possible to obtain a large electromotive force, which is of great practical effect.
