SPANNER FOR NUTS AND BOLTS OF DIFFERENT SIZES WITHOUT MOVING PARTS

Abstract

The invention relates to a spanner for nuts and bolts, of various sizes, which has no moving parts. The spanner consists of a body (1), solid or with openings (5), to reduce weight. At the ends of the body (1) there are holes (2), polygonal in shape, where each one partially overlaps the one next to it. Holes (2), of different sizes, can also be present on each side (3) of the body (1), which are perpendicular to the inclined surface of each side (3) of the spanner.

Claims

1. A spanner for nuts and bolts of various sizes without moving parts, consisting of a body (1), solid or with openings (5), with two ends, two sides (3) on either side of a central, longitudinal axis (4) of the body (1), where at least at one of the ends there are at least two holes (2), polygonal in shape and of different sizes, characterized in that the upper surface of the holes (2) is inclined, with the last hole (2a) towards inside being at a higher point with respect to the last hole (2b) towards the outer point of the spanner, while respectively all the holes (2) are perpendicular to the inclined surface of each side (3) of the spanner and each hole (2) partially overlaps its adjacent one.

2. The spanner for nuts and bolts of various sizes without moving parts, according to claim 1, characterized in that the end of each side (3) has at least two holes (2), with different dimensions.

3. The spanner for nuts and bolts of various sizes without moving parts, according to claim 1, characterized in that a hinge is inserted between the body (1) and the end, which turns up to 90° perpendicularly to the central, longitudinal axis (4).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The invention will become apparent to those skilled in the art by reference to the accompanying drawings in which it is illustrated in an indicative, non-limiting manner.

[0012] FIG. 1 shows a plan view of the invention, the spanner having 4 different holes on each of its two ends, for the respective size of nuts and bolts.

[0013] FIG. 2 is a vertical section of a spanner for different sized nuts and bolts, showing the different holes on its two sides and on its two ends, depending on the respective dimension.

[0014] FIG. 3 is a 3D image of a spanner for nuts and bolts of different sizes, without moving parts, in accordance with the present invention.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

[0015] Referring now to the accompanying drawings we will describe illustrative embodiments of the spanner for nuts and bolts of different sizes, so that its technical features and innovation may become apparent.

[0016] The different size, non-moving-part spanner of the present: invention consists of a single body (1), FIG. 1, with different-sized holes (2), at both ends of the body (1). At each end of the body (1) there are at least two holes (2), where each of them partially overlaps the adjacent one, FIG. 3. The size of each hole (2) increases in relation to the previous one, considering the holes (2) from the end to the center of the body (1) of the spanner. The partial overlap between the holes (2) helps reduce the overall size of the spanner. The holes (2) are designed for polygonal nuts and bolts, i.e. components with three or more sides. Therefore, the holes (2) have a triangular, square or generally polygonal shape, so that each hole (2) fits on the respective nut or bolt, with two or more vertices and with their corresponding sides.

[0017] In an advantageous embodiment of the invention on each of the two sides (3), FIG. 2, of the body (1) there may be holes (2) of different sizes, so that at each end and each side (3) there are at least two holes (2), where one is overlapped by its adjacent one.

[0018] In order to have the necessary space for the user's hand, when using the spanner and especially the holes (2) towards the center, it has been designed to have the necessary inclination. Thus the upper surface of the holes (2) is inclined, with the last hole towards the inside being at a higher point compared to the last hole (2b) towards the outer point of the spanner, while respectively all the holes (2) are perpendicular to the inclined surface of each side (3) of the spanner. This avoids the user's usual movement, which requires the spanner to be tilted upwards, thereby reducing the contact of the spanner's head with the bolt or nut, in order to create the necessary space for the user to rotate a standard open-ended or adjustable spanner. The body (1) of the spanner can be compact or have one or more openings (5), mainly to reduce the total weight of the spanner, if this is deemed necessary.

[0019] In yet another alternative implementation of the invention, between the body (1) of the spanner and the holes (2) there may be a hinge, allowing the end with the holes (2) to be turned up to 90°, with respect to the central, longitudinal axis (4). Turning the end will be possible in both directions, facilitating the use of the spanner even in hard-to-reach places.

[0020] It should be noted at this point that the description of the invention was carried out with reference to illustrative embodiments, not being limited thereto. Therefore, any change or modification regarding the shape, dimensions, morphology, materials used and construction and assembly components, as long as they do not constitute a inventive step and do not contribute to the technical development of what is already known, are considered included in the purposes and visions of the present invention.
