Description

Technical Field

[0001] The utility model relates to a shovel, and in particular to a shovel technology which can integrate light weight and ergonomic structure to allow users to operate and use the shovel in a more convenient, relaxed and practical way. Background Art

[0002] A shovel or spade is a very common digging tool in daily life. It is mainly used to dig soft materials such as coal, snow, soil or sand, and has been widely used in agriculture, mountaineering, camping, construction and gardening. A conventional shovel consists of a handle and a shovel face. According to the purpose, it can be roughly divided into garden shovels, military shovels, snow shovels, mountaineering shovels and toy shovels. Generally speaking, a pointed shovel head is more suitable for digging, while a straight shovel head is more suitable for shoveling soft materials such as coal, snow, soil or sand. As for the spade head with a blunt-angled shovel head, it is mainly used in agriculture, mining and post-disaster rescue.

[0003] According to what is known, the representative patents of the conventional shovel technology are as follows:

[0004] 1. Patent No. 294571 of the Taiwan Appearance Notice of the Shovel, which includes a handle and a shovel face, and the front end face of the shovel face is provided with a transversely extending serrated structure. Although the patent can cut harder soil through the transversely extending serrated structure; however, the transversely extending serrated structure is indeed less ergonomic when cutting harder soil, making it difficult to apply force to cut the soil, thus causing inconvenience and trouble in the use of the shovel.

[0005] 2. Patent No. 322681 of Taiwan Utility Model Publication, “Improved Shovel Structure”, includes a handle and a shovel face, the front end face of which is provided with a transversely extending serrated structure. Although this patent can also cut harder soil through the transversely extending serrated structure, it is just that the transversely extending serrated structure is not ergonomic when cutting harder soil, making it difficult to apply force to cut the soil, thus causing inconvenience and trouble in using the shovel.

[0006] 3. The patent for "Gardening Shovel" in Taiwan Utility Model Announcement No. M355552, which consists of a shovel part and a handle part, is mainly composed of concave grooves arranged around the shovel part, and each of the concave grooves is provided with a blade part. Although the patent has a cutting function, it does not integrate lightweight, ergonomic and side serrations, so that users cannot use the shovel in a more convenient, easy and practical way, and the side serrations cannot be used to cut harder soil, which causes inconvenience and trouble in using the shovel.

[0007] In view of the fact that the conventional shovels and the above-mentioned patents are indeed not perfect in terms of operating functions and convenience, there is still a need for further improvement; therefore, the inventor of the present invention has actively invested in research and development with the accumulated rich shovel research and development design capabilities and experience over the years, and finally produced the research and development results of the present utility model through continuous design, trial production and testing.
