Description

Description
Title of Invention: CAULKING GUN EXTENSION SET
[0001] The present invention relates to an extension kit for a caulking gun. The invention also relates to a caulking gun containing the extension set. The invention also relates to a push rod with a universal adapter. The invention also relates to the universal adapter.
[0002] A caulking gun is generally known. Most caulking guns for professional use include a handle, a trigger assembly, an elongated cylindrical tube that includes a plunger holder and push rod, wherein a cartridge of sealing material and / or glue or other products can be placed in the holder. The tube prevents deflection of the push rod, thereby ensuring an even release of sealing material, such as glue or sealing material, when the trigger is operated.
[0003] The cartridges with sealing material and / or glue or other products, for example packed in a bag or in a plastic sleeve, are designed to be mounted in the caulking gun, which is manually operated by an employee to dispense the material contained therein. The length of a typical conventional caulking gun varies on average between 20 and 40 cm. Due to the short length of a caulking gun, a workman must operate such a gun within his arm's length. For example, when a workman works on a ladder where freedom of movement is limited, he must repeatedly move the ladder to reach new work areas. This is detrimental to safety and the operating speed. A further dis advantage is that the length of an existing caulking gun provides difficult working comfort, especially with lower surfaces, for example when applying glue or sealant to floors and skirting boards and / or joining floors.
[0004] The object of the invention is to extend an existing caulking gun in order to con siderably improve the working comfort. A further purpose of an extended caulking gun is to enable an employee to reach farther-reaching work areas from any location.
Another object of the invention is to provide safer and more ergonomic working conditions in which the sealing material and / or glue can be applied more accurately to distant surfaces.
[0005] This object is achieved by providing the caulking gun with an elongated cylindrical tube, also known as an extension tube, which is provided on both ends with screw thread on the outside, the cylindrical tube being connected to each other by a coupling ring provided with screw thread on the inside and wherein the extension sleeve comprises a push rod provided with a plunger and a fitting piece, the fitting piece connecting to the pressure rod in the cylindrical tube of the caulking gun being a universal adapter having a cylindrical shape with conical rounding to the inside.
[0006] The plunger and the adapter are screwed to the ends of the push rod. The adapter according to the invention is provided with a hollow space in order to be able to screw the adapter onto the pressure rod of the extension tube.
[0007] It has surprisingly been found that existing caulking guns can easily be extended with one or more cylindrical tube or tubes (extension tube (s)), a coupling ring and a push rod provided with a plunger and a fitting piece, wherein the fitting piece that connects to the push rod in the cylindrical tube of the caulking gun, has a cylindrical shape that is conically rounded in order to accurately connect to the plunger of the push rod of the caulking gun to be extended.
[0008] An advantage of the present invention is that by extending the caulking gun, the working comfort is considerably improved. Moreover, this mainly has ergonomic ad vantages, but also the freedom of movement and safety will increase, especially if the workman has to stand on a ladder. Another advantage is that with the extended caulking gun a uniform delivery of sealing material or glue is ensured.
[0009] Examples of caulking guns are manual caulking guns, hydraulic caulking guns, elec trically operated caulking guns, battery caulking guns and pneumatic caulking guns. The extension set according to the invention can be used on any of the aforementioned caulking guns.
[0010] The push rod [Fig. 1] is preferably a round or square rod. The push rod can be made of aluminum. The invention is not limited thereto. For example, it is possible that the push rod is made of plastic. It is also possible that the push rod is provided with internal and / or external thread to mount a plunger and universal adapter or not.
[0011] The universal adapter as described in [Fig. 3] can be made from a material selected from metal, aluminum, Teflon, polyethylene, polycarbonate, nylon 6 or nylon 6,6 or a mixture thereof. The fitting piece (5, 6) can be manufactured via milling but also via injection molding. The adapter is universal and therefore fits precisely on every push rod with plunger. This provides an enormous ease of use and is easy to assemble. The fitting piece is preferably provided with a magnet on the inside.
[0012] The pressure rod and the fitting piece can be manufactured in one piece, for example via injection molding. The push rod and the adapter can be made from a material selected from teflon, polyethylene, polycarbonate, nylon 6 or nylon 6,6 or a mixture thereof. The push rod and the adapter together have the same length as the cylindrical tube of the extension tube without the plunger.
[0013] In another embodiment, the push rod, the fitting piece and the plunger can be made in one piece. The assembly can be made from a material selected from metal, aluminum, Teflon, polyethylene, polycarbonate, nylon 6 or nylon 6,6 or a mixture thereof, for example via injection molding. The length of the push rod, the fitting piece and the plunger is then equal to the length of the cylindrical tube of the extension tube.
[0014] The extension tube can be made from a material selected from metal, aluminum or plastic. The extension sleeve preferably consists of plastic or aluminum in order not to make the whole too heavy so that it remains easy to handle. The extension tube can for instance be manufactured from PVC or polyethylene.
[0015] The coupling ring [fig.2], which connects to the extension tube, is threaded on the inside and can therefore be easily connected to the extension tube with a thread on the outside. The coupling ring can be made from a material selected from metal, aluminum or plastic such as PVC or polyethylene. The coupling ring can also be made from a combination of metal and plastic. The coupling ring can be provided with a non-slip coating so that the ring does not come loose during use. The coupling ring is preferably made from plastic such as PVC or aluminum. It has been found that a coupling ring made of PVC has an advantage in particular that the coupling ring does not loosen during use. More preferably, the extension sleeve and the coupling ring are made of the same material.
[0016] The extension tube and the coupling ring together may possibly also be made in one piece.
[0017] The present invention also relates to a push rod (1,2) for the extension tube and
comprises an existing plunger and a universal adapter (5, 6) wherein the adapter (6) has a cylindrical shape with a conical rounding to the inside (7). The conical rounding is located at the end of the fitting piece (7). The conical shape is designed in such a way that the adapter fits accurately with existing plungers. The fitting piece can preferably be provided with a magnet on the inside. The total length of the push rod is equal to the length of the extension tube plus the length of the conical rounding of the adapter (7).
[0018] The invention also relates to the fitting piece or adapter [Fig. 3], wherein the adapter has a cylindrical shape (5, 6) with a conical rounding to the inside (7). The fitting piece preferably has a hollow space with a diameter that is smaller than the diameter of the fitting piece. The fitting piece preferably consists of a material selected from teflon, polyethylene, polycarbonate, nylon 6 or nylon 6,6 or a mixture thereof. The fitting piece is preferably made from nylon 6 or nylon 66. The fitting piece can be manu factured by injection molding. The fitting piece which is provided with a hollow space on the inside is preferably provided with a magnet. The magnet can in this case ensure a close connection between the adapter and the plunger. The fitting piece according to the invention does not make contact with the cylindrical tube, so that no friction takes place and, therefore, no additional force is required when pushing the push rod.
However, the plunger fits closely with the cylindrical tube for products in bag packaging. The plunger has a size that fits in the tube for processing products in tube packaging.
[0019] The invention also relates to an extension set for a caulking gun comprising a
cylindrical tube, said extension tube, which is provided on both ends with screw thread on the outside, a coupling ring [Fig. 2] which is provided with screw thread (8) on the inside, push rod (1, 2) provided with an existing plunger and a universal adapter (5,6), the adapter having a cylindrical shape (5) with a conical rounding to the inside (7).
This embodiment can be repeated until the caulking gun has the desired length. It goes without saying that the length of the extension tube can vary depending on the length of the extension set.
[0020] In another embodiment it is possible to provide the extended caulking gun with a further coupling ring according to figure 4 (9, 10), wherein the coupling ring is coupled on one side to the extension tube and on the other side is provided with external screw thread (11) to be easily coupled in such a way to, for example, an adhesive distribution comb.
