Description

Improved rotating finger flexometer.

The present Utility Model application consists as indicated in a "Flexometer perfected of rotating nail ", whose new characteristics of construction, conformation and design fulfill the projected with a maximum safety and effectiveness.

More specifically the invention relates to some  improvements introduced in the extreme part of the tape a flexometer, where the tape nail is mounted, it can turn on itself with respect to the tape, so that in each 180º turn said nail is held in a position fixed.

Flexometers or tape measures are used to take measures horizontally, but if you want to take measures vertically, being the measure we want to take greater than 1.5 meters or more, depending on the flexometer, it is it is necessary to hold the nail of the same ensuring its verticality by how much flexibility it allows for buckling or bending forward.

The state of the art of the flexometers, in as far as the end of the tape is concerned, it is formed by tapes whose end is provided by a nail or stop formed by a metal sheet bent at right angles and that in its part horizontal is attached to the end of said measuring tape by screws, rivets or equivalent means, so that the flexometer allows you to take measurements by just one person with just hold or support the end of the tape, the nail, at one point and stretching the tape the reel unrolls tape so that extends from inside the flexometer, that is to say its housing out. In some flexometers the nail is attached to the end of the tape by fixed means, however it is usual that the same move about 2 or 3 mm. approximately, for the measurement of Interior and exterior.

However, the state of the art does not remain  reflected any flexometer capable of turning the nail on itself same with respect to the end of the tape. The usefulness of this invention is that when measuring distances vertically, and how consequence of the concavity of the measuring tape in the direction transversal, it yields forward, preventing vertical measurements, and also highlight that when changing in order to avoid such a fall it is not graffiti on its back.

Other measurement positions are not possible with conventional flexometer tapes, as the measurement in horizontal of the nail itself makes the tape separate from the horizontal plane, the measurement being distorted with respect to than it really is, since the very height of the nail prevents that the tape is in contact with said horizontal plane.

To this end, the tape starts in one of its features of printing it on both sides of so that it can be measured by supporting the tape on the face concave on the object to be measured, since for its part convex the Tape never bends.

The improvements introduced in the flexometer are based on the incorporation at the end of the tape a nail arranged in the plane perpendicular to the tape attached in solidarity with a cam, whose particular configuration allows the turn of the same (nail and cam) and its interlocking in two positions determined, in combination with retention means of the nail-cam assembly in the two fixed positions of work, and some means of fastening to the tape.

The aforementioned stability positions of the nail-cam set are diametrically opposite: in the first position (0º) the nail is in the plane perpendicular to the tape and its end points in the direction perpendicular to the lower longitudinal edge of the tape; Y in the second position (180º turn) the nail is in the same plane perpendicular to the tape but its end points in opposite way.

Preferably the cam is formed by a substantially cylindrical body that extends perpendicularly from the top of the back face of the nail, but said cylindrical body is affected by its upper and lower part by a plane that cuts the cylinder longitudinally. This way, thanks to these two planes provided on the cam in collaboration with the retention means, it is guaranteed that the nail-cam assembly stay in one of the two Possible fixed positions described above.

The nail-cam assembly is mounted on the concave surface of the end of the tape, and more specifically in its central area, so that one of the planes of the cam is in contact with the central part of the end of the tape, and the nail is always outstanding.

The means of retention of the set nail-cam, which are mounted on the cam and cover it partially or totally, they allow the complete 360º rotation of the nail-cam assembly and its interlocking in both Fixed work positions: 0º and 180º. Said retention means they are formed by a cover that is mounted on the cam, whose contour fits perfectly to the plane of the cam, so that guarantees the interlocking of the nail-cam assembly in One of the two work positions.

According to this configuration, the cam is  arranged in the channel formed by the cover and the upper face of the tape, getting attached to it and being in a position fixed.

The fastening means of said set nail-cam allow the set nail-cam and retaining means remain attached to the end of the tape, and are made up of plates that are mounted at the same height as the cover but on the face back of the tape. Both pieces, cover and plates, are maintained  joined by screws or rivets, which cross the headband. The holes provided in the tape are colossi, for allow a certain tolerance of the tape, so that it can move slightly to fit the contact surface flat cam.

Optionally, to allow the nail to move forward or backward for measuring indoor or outdoor, a cabot is incorporated at the end end of the cam, with a diameter slightly larger than the diameter of the cam The end of the tape is provided with an adapted hole so that the cabot protrudes slightly below the belt. This hole will have a length greater than the thickness of the cabot to allow the set to move nail-cam, specifically a length equal to the sum of the thickness of the cabot and the thickness of the nail.

Other details and features will go away showing in the course of the description that to given below, in which reference is made to the drawings that to this memory they are accompanied and in which a mode of practical embodiment of the invention.

In one of the preferred embodiments of what it is the object of the present invention and as can be seen in Figure 1-6, the tape (10) incorporates a perfected nail assembly (15) formed by the nail (15a) and the cam (13), on which (15) a cover (11) is incorporated. Cited cover (11) has a central area noticeably semi-cylindrical (11a) that extends outward according to wings (11b), affected on its upper surface by measuring stripes (22), and some holes (27) where the screws or rivets (12) secure it to the upper face of the tape metric (10). The nail assembly (15) is mounted prisoner between the central area (11a) of the sheath (11) and the upper face of the tape (10), so that it is subject but without being prevent rotation of the cam assembly (15).

The nail assembly (15) is formed by a vertical portion (15a) whose function is to make a stop with the surface to be measured, from whose rear face (16) emerges perpendicularly a substantially cylindrical body or cam (13), said cam (13) attached at its other end to a cabot (14), see Figure 15-19. The cam (13) has a body noticeably cylindrical, but in its upper and lower part they form two planes (29a-29b) that cut longitudinally the cylindrical portion by the upper part e lower. The cabot (19) arranged in the final part of the set nail (15) has a cylindrical configuration of greater diameter than the diameter of the cam (13) and of small thickness. Cited cabota (14) has the double mission of keeping the nail (15) subject to final section (24) of the tape (10) through the introduction partial of it in the hole (23) provided in the belt (10) with a certain slack, and on the other hand to make a stop for the back surface of the cover (11).

As can be seen in figure no. 1-6, the nail (15) is in its position of 0º work, but you can perform a 180º turn, since the clearance between the central part (11a) of the sheath (11) and the upper face of the tape (10) with respect to the cam (13) allows to make the turning movement of the whole nail set (15), until reaching a stable position.

In addition, as shown in figure no. 7-10, the final section (24) of the tape (10) presents collision through holes (18) that contribute to the fixation of the nail assembly (15) in one of its two fixed positions. The stretch end (24) of the tape (10), which has a profile surface concave, apart from presenting the colossal drills (18) adapted to allow the passage of the rivets (12), it also incorporates another through hole (23) in a position further away from the end of the tape (10) adapted so that the bottom of the cabot (14) is partially enter it and thus enable movement of the nail assembly (15) forward and backward.

The extreme edge of said final section (24) is endow with a slit (25) in the central part, so that the two portions or wings (26) left on the sides when mounted the set rest against the rear face (16) of the portion vertical (15a).

As can be seen in figure no. 11-14, the cover (11) has a surface formed by a central section of configuration noticeably ribbed (11a), which extends laterally forming two wings (11b) that extend slightly inclined upwards. Bliss central corrugated portion (11a) has a flat surface (31) in its central section, so that said flat surface (31) is arrange just on one of the flat surfaces (29a) or (29b) of the cam (13) and immobilize the nail assembly (15) in a position u in other, which correspond to the positions of 0 and 180º.

Through holes (27) are incorporated in both wings (11b) of the cover (11), which allow to fix the cover (11) with the final section (24) of the tape (10) and with the plates (17) using rivets (12), all allowing the nail assembly (15) can perform the turning movement on each other same.

The front face of the cover (11) is provided with a plurality of measuring stripes (22), specifically at the edge end of the two wings (11b). However, the back side does not It is engraved with stripes.

Figure 20-22 shows a of the two plates (17), of rectangular configuration, of edges blunt, and thin, provided with through holes (30) adapted to pass the screws or rivets (12). Sayings screws or rivets (12), as shown in figure no. 23-25, have a stepped section formed by two cylindrical portions (20-21) growing towards above and at the top a cabot (19) that prevents the nail assembly (15) can move freely and thus ensure the position of the same in the working position, either the position 0º or 180º.

Suitably described the present invention in correspondence with the attached figures, it is easy to understand that any modifications of detail deemed convenient as long as they do not alter the essential characteristics of it, which is summarized in the following claims.
