Description

[0001] The present invention relates to a drill stand according to the preamble of claim 1.

[0002] It is known in the art to use a drill stand where drill holes are to be made in for example floors or any other objects. The drill stand is used to carry the drill which is especially useful if drilling is a long lasting operation.

[0003] These known drill stands comprise a base carrying the drill holder. The base usually has a somewhat rectangular shape, the drill holder being provided at one end of said base. The base commonly is provided with a total of four leveling feet, so as to place the drill stand exactly horizontally or level with any other surface. The leveling feet are provided at corners of said base.

[0004] Tendency of most manufacturers is to provide four leveling feet so as to ensure a supposed high stability. However, other manufacturers apply three leveling feet which is thought to improve a quick installation since a smaller number of leveling feet has to be adjusted. However, in many cases it is more cumbersome to ensure a sufficient level of stability when using only three leveling feet.

[0005] There is no solution available for cases where a user would like to switch between a quick installation on the one hand and a highest stability on the other hand.

[0006] The invention aims at providing a drill stand that can be used in all cases, whenever a highest stability is desired or a quick installation.

[0007] So as to obtain at least one of the above mentioned aims, the invention provides a drill stand according to claim 1. This drill stand provides the advantages as aimed according to the present invention.

[0008] It has also shown that the invention provides a drill stand that has an even higher stability than any drill stand presently available on the market. Due to the position of the fifth leveling foot the stability is improved when all five feet are used. Also, it has shown that leveling of the drill stand can be performed quicker by using the drill stand according to the present invention. Such synergistic effect is a surprising but advantageous effect.

[0009] The invention therefore relates to a drill stand, comprising a base for supporting a drill holder, said base comprising at least four leveling feet for leveling said base, said leveling feet being positioned at corners of a quadrangle, said drill stand being characterized in that the base further comprises a fifth leveling foot, said fifth foot being positioned substantially in between two adjacent feet.

[0010] According to a preferred embodiment, said fifth foot is positioned outside said quadrangle formed by said other four leveling feet. Such improves the total stability of the drill stand, since an area is covered by the five leveling feet is larger than the area covered by the said four feet.

[0011] According to another embodiment, it may be preferred to position said fifth foot on or inside said quadrangle formed by said other four leveling feet, since such does not interfere with the total area covered by the other four feet. The, the total surface covered by the drill stand is not increased.

[0012] As a matter of fact, the said fifth foot may be positioned at a front side of the drill stand, which is the side where the drill holder is positioned, or at the rear side of the drill stand. However, so as to obtain a maximum stability, preference is given to a drill stand as mentioned above, said base comprising a drill holder extending from said base relatively closer to a first set of two leveling feet than to a second set of two leveling feet, wherein said second set of two leveling feet is positioned relatively further away from said drill holder, said fifth leveling foot being provided substantially in between said second set of two leveling feet. According to this preferred embodiment, the fifth foot is positioned at the said rear side.

[0013] However, depending on the situation where the drill stand is used for drilling a hole, it may be preferred that a support for said drill holder is provided near said fifth foot. Such simplifies the positioning of the front side of the drill stand which is preferred if the surface the drill stand is positioned on has a highly irregular shape of consistency at said front side.

[0014] According to a preferred embodiment, said first set of two leveling feet is positioned parallel to said second set of two leveling feet. For, such provides highest stability in the direction from front to rear, which is required when drilling oblique holes wherein the drill holder is slanted backwards.

[0015] A drill stand comprising a base that is embodied such that the leveling feet of the left side and right side are positioned mirror symmetrically is preferred. For, such yields highest stability in a direction from left to right, vice versa. In such embodiment, the fifth foot can be positioned on the line mirror symmetry for yielding a highest stability in the front to rear direction. As a consequence, preference is given to a drill stand wherein said four leveling feet are positioned such that a first leveling foot of a first set and a first leveling foot of a second set are positioned mirror-symmetrically with respect to a second leveling foot of a first set and a second leveling foot of a second set of leveling feet, and wherein said fifth foot is positioned on a line of said mirror-symmetry.

[0016] An easy leveling may be obtained if each leveling foot being received in a threaded hole, said foot being equipped with mutual thread, optionally provided with a nut for locking said foot with respect to said base. Leveling is obtained by turning each foot in said threaded hole for moving an end of said leveling foot in or out of said hole.

[0017] According to a further embodiment, the invention relates to a base for a drill stand according to the present invention, said base comprising at least four leveling feet for leveling said base with respect to a surface, said leveling feet being positioned at corners of a quadrangle. The base is characterized in that it further comprises a fifth leveling foot, said fifth foot being positioned substantially in between two adjacent feet.

[0018] According to a still further embodiment, the invention relates to a method for leveling a drill stand according to the invention, comprising the steps of: - positioning the drill stand on a surface and adjusting a first set of two leveling feet and the fifth foot for obtaining a substantially level position, and - subsequently adjusting a second set of two leveling feet for providing a maximum stability; said fifth foot being positioned substantially in between said set second set of two leveling feet. Such provides a very quick and easy leveling of the drill stand according to the invention. Such quick installation combined with an optimum stability cannot be obtained with any drill stand presently available.

[0019] Hereafter, the invention will be further described by means of a drawing. The drawing shows in:
