Description

HAMMER FOR INSTALLING STAPLES IN NEARBY AND OTHER

SIMILAR SURFACES

FIELD OF THE INVENTION

The present invention is related to the tools used in wire fence installations, more specifically it refers to a hammer perfected to install metal clips on fences and other similar surfaces that facilitates the operation making it easier, more practical and faster and more precise. .

BACKGROUND OF THE INVENTION

In the field of laying perimeter fences with smooth wires, barbed wires and other type of wires where said wires must be fixed on wooden posts spaced at a predetermined distance that are buried and fixed vertically in the ground along a length determined to delimit an area, nails and hammers are generally used, where the nails are nailed to wooden posts to a certain depth at a height where the wire will be fixed, leaving an exposed section that bends with the hammer on the wire to hold it and hold it tight. However, this type of techniques and materials used cause problems in the installation since the nails usually break or do not hold the wires well so the installation is poor.

To solve this problem, a tool called a pressure-operated air-operated gun was developed that fires staples that are shaped like “U ^* whose extreme ends are sharp; said staples salts shot at high speed against the wooden posts and these penetrate holding the cables. However, if a compressed air gun is not available, a staple can be held closely with the fingers in one hand and a hammer in the other to drive them manually, this implies a high probability of injury to the user as the tapping with The hammer may not be accurate and the user can hit the fingers. The present invention is directed to an improved hammer-like tool to magnetically hold a clip during its installation and thereby avoid the use of the hand to hold and position the clip. A search was conducted to determine the closest state of the art, the following documents being found:

Document US4073327 from Ottis D. Pearson of February 14, 1978 (document D1) which reveals a conventional hammer that is equipped with a special magnetic insert in the head to facilitate the collection of nails and tacks before using the hammer was located. The special magnetic insert is made of steel hardened with high carbon content that is heat treated before magnetization and then pressurized in a non-magnetic hard metal shield and the assembly is further pressed into a circular recess in the hammer head presenting a flush surface that can then Perform the combined functions of magnetic pickup and conduction for long periods of time without affecting the function of the magnet. The invention essentially comprises a two-head tool having a drive head composed of conventionally heat-treated steel that defines a pair of ears or nails pulls nails and at the opposite axial end a magnetic head having a magnetic insert for use in collecting of nails and tacks and start them on the material to be fastened before driving with the opposite end. The device allows a person to secure a fence quickly and safely; It provides the opportunity to have a free hand to perform other functions related to work on the fence.

However, it should be noted that it comprises a magnetic insert of hardened steel pressed into a shield of non-magnetic hard material such as austenitic stainless steel or other high nickel alloys known for their hardness, durability and non-magnetic properties. The combination of the shield and the magnetic insert are snapped into a recess in the head of a conventional hammer, whose face is rectified to present a smooth surface, this means that due to excessive use or for long periods of time it can cause the shield and insert can get out of the hammer head recess, stopping working; In addition, the magnetic effect is lost by constant tapping with the head where the magnetic insert is arranged. Document CN206544146 U by Tang Jianming et al. of January 23, 2017 (document D2) which describes a utility model of a multi-purpose hammer, which includes a hammer configurable in parts to have a hammer suitable for various tasks that are not for the use of the developed invention. Additionally, the forms and uses of the invention of document D2 are for a conventional hammer in which uses are adapted according to the need for nailing or nailing of the objects to be worked. The hammer of document D2 does not reveal or suggest a hammer that is specially designed to place metal clips on fences and other similar surfaces.

The patent application document US20080184494 A1 by Govotski Benjamín V. of February 5, 2008 (Document D3) which discloses a hammer with metal clip holder to place staples on a suitable surface, such as staples in the form of U during the installation of cables, such as barbed wire or wire cloth, as well as chicken wire. It includes a helmet that defines an opening and a handle that extends along a main axis of the opening. The helmet may include magnets to facilitate the fastening of a clip in the helmet. The handle may include marks, such as those that would be used to properly distance the clips during the use of the staple bra.

Unlike the developed system, the invention described in document D3 only contains one position, while the developed invention allows the clips to be placed both horizontally or vertically depending on the position in which it is required to strike to place the same. On the other hand, the hammer of document D3 alone has a striking surface and a graduated scale for the placement of staples, which differs totally from the developed invention where two striking areas are available to amplify the force required in the placement of staples

Given the need for a hammer to install staples on fences and other similar surfaces, it allows a person to secure a fence quickly and safely; providing the opportunity to have a free hand to perform other functions related to work in close, it was that the ^'present invention was developed. OBJECTIVES OF THE INVENTION

The present invention has as one of the primary objectives, to make available a hammer to install staples in fences and other similar surfaces that allows the user to maneuver the staples on the fence without danger of injuring the fingers and in turn, prevent the staple of the close bounce towards the user, probably avoiding eye injuries or bodily injuries. Another object of the invention is to allow said hammer to install staples in fences and other similar surfaces, which also provides the user the opportunity to have a free hand to perform other functions related to work on the fence such as holding the cable against the post, secure the pole or tension the cable.

Another object of the invention is to allow said hammer to install staples in fences and other similar surfaces, which is also structurally simple, practical and functional.

Another objective of the invention is to allow said hammer to install staples in fences and other similar surfaces, which also allows, on the one hand, the temporary fastening of staples by means of magnetic elements while the staple is stuck in the post in a first stroke and already driven allows turning the hammer to hit with a solid and firm hitting head, so as to avoid damage and damage to the head with magnetic elements.
