The present invention relates generally to an improved breaking device, and more particularly to a breaking device of application safety, which is used in combination with a baton and breaker to smash windows, and yet, when the breaking device is not used for this purpose, the breaking bolt of the breaking device is hidden in the conical head to avoid scratching any persons or articles and ensure user safety.
Law-enforcement officers, guards and community patrols often face unpredictable physical conflicts and emergencies on duty and they usually carry batons for self-defense. However, if any emergency arises, they must immediately enter a house or a car and rush to emergency rescue by smashing door or car windows. Since most door or car windows are made from reinforced glass, they will probably miss the perfect rescue time if they spend a minute searching for a window breaker to smash the windows; therefore, in most cases, batons are used to smash door or car windows for the sake of convenience. However, because the conventional batons have no functions of breakers, it is time consuming the ineffective in such occasions and usually delays the rescue time; besides, in the smashing process, the shards of glass are likely to bounce off and hurt the rescuers due to any improper application of force, which is also a troublesome problem.
Thus, relevant practitioners have developed a baton 8 as shown in
To overcome the shortcomings of the conventional design, although the applicant's previous breaking device (application number: 105214300) as a utility model patent fails to overcome these shortcomings, it can be put into normal use without major problems. However, in case of improper manual operation, the breaking bolt is difficult to collapse or extend smoothly. Despite this minor deficiency that can be remedied by adjusting the dimensions of elements, the applicant, to achieve perfect condition of invention, has been continuously working on refinements of the invention in order to ensure flawless use of the invention.
Based on the foregoing, the inventor of the present invention, after continuous research and improvement, has eventually designed the present invention, namely, the improved breaking device, which is the purpose of the present invention, relating to a breaking device of application safety and used in combination with baton and breaker to smash windows, and yet, when the breaking device is not used for this purpose, the breaking bolt of the breaking device is hidden in the conical head to avoid scratching any persons or articles and ensure user safety.
To meet the purpose of the present invention, the improved breaking device is comprised of a base, a breaking bolt, an elastic element and a conical head, wherein:
As shown in
The base 1 has the first binding site 11 on one end, a body B combined with the first binding site 11, a registration site 12 on the other end of the base 1, the registration site 12 having a sliding section 121 and the first limit section 122.
The breaking bolt 2 has a sharp conical tip 21 on the front end, and a retaining lip 22 at the back end of the breaking bolt 2, the retaining lip 22 being supported by the front face 13 of the registration site 12 at the bottom.
The conical head 4 is linked with the registration site 12 of the base 1, the conical head 4 having a conical surface 41 on the front side, the conical surface 41 including a hole 421 in the middle, the hole 421 connecting to a holding hole 42 in the conical head 4, the holding hole 42 having the second limit second 422, and the breaking bolt 42 and the elastic element 3 being inserted in the holding hole 42, the elastic element 3 being linked with the outer periphery of the breaking bolt 2.
Said first binding site 11 has the first thread section 111, the body B having the second binding site B1, the second binding site B1 including the second thread section B11, the first thread section 111 and the second thread section B11 interlocking with each other.
Said body B is a baton (as shown in
As shown in
To summarize, the breaking device of the present invention is used in combination with baton and breaker for smashing door and car windows. When not in use, the breaking bolt is hidden in the conical head to avoid scratching any persons or articles and ensure user safety. Therefore, the existing shortcomings of the conventional breaking device are overcome with a new technology of the present invention, proving the novelty and progressiveness of the present invention as a utility model patent.
The embodiment provided by the present invention is only used to explain the technology of the present invention, but does not attempt to, impose any form of restrictions to the present invention with said embodiment, and therefore, where there is made in the spirit of the invention and the following claims under the same in relation to any changes to the present invention, all should still include in the scope of the present invention.
