The present invention relates to a series of surveying tools, in particular rolled tapes, used to measure length.

As shown in Figure 1, the tape measure 92 of the reel-shaped tape measure according to the prior art is an elongated strip-shaped cold-rolled metal flake, the end portion of which is fixed to the L-shaped hook 91 by rivets , The horizontal plate at one end of the hook 91 is fixed on the tape measure 92, and the lower side of the tape measure 92 has a reinforcing metal piece 93 in a symmetrical manner with the tape measure 92 of the tape measure 92 and the hook 91. The horizontal plate, and the reinforcing metal piece 93, these three are connected by rivets.

As shown in Fig. 2, when the length is measured, the vertical plate at one end of the hook 91 is hooked to the measurement start point of the object to be measured. By the way, the starting point is generally at right angles, but when this portion is inclined or arched, for example, a cylindrical or arched table circumference or a neck circumferential table, the hook 91 is not easily caught, but rather easily. Because they slip off, they cannot be surveyed efficiently. And even when the tape measure 92 is shaken during the measurement, the hook 91, which was also hung, slips off easily. Therefore, in order to improve these problems, a method as shown in FIG. 2 has been proposed, which is easy to hang by adding a sharp hook angle 94 at the end of the hook 91 or as shown in FIG. 3. The method of fixing the hook 91 with the fixing nail 95 was used.

However, this use method was very inconvenient for the user, the hook 91 of Figure 2 can be fitted to the hook angle 94 only if there is a concave groove at the measurement start point of the object edge. And the position fixing nail 95 of FIG. 3 can also be driven only by a wooden object, and can not be driven by a hard material object, which has been very limited in use.

The present invention has been devised to solve the above problems, and provides a kind of hook structure for preventing the tape measure from slipping off the object to be deviated, and even if the measurement point of the object is inclined or arcuate The purpose of this is to prevent the tapered hook slipping off.

Features of the anti-slip hook attached to a scroll tape measure of the present invention is as follows. The entire outer surface of the hook's vertical plate is covered with a layer of soft rubber, which is made of an anti-slip rubber material, which extends the non-slip piece downward from below the vertical plate. .

Another type of scroll tape measure in the present invention is characterized by the anti-slip hook. The outer surface of the hook's vertical plate was wrapped with a hard plastic shielded L-shaped shield, and another extension piece was joined to the underside of the protective rod, and the soft rubber wrapped around the protective plate's vertical plate and the outer surface of the extension. I made it.

[First Embodiment]

Figure 4 and Figure 5 is a three-dimensional exploded view and assembly diagram of the anti-slip hook head of the reel-type tape measure according to the present invention. The scroll-shaped tape measure 10 shown in the figure is comprised of the tape measure case 1 which can pull out the tape measure 2, and the anti-slip hook 7 provided in the front end of the tape measure 2, The structure is , A-shaped metal hook (3) and padded piece (6) inside the tape measure (2) is to be wrapped up and down, and also fixed by rivets to combine. The horizontal and vertical plates (i.e. end supports) of the hook (3) are vertical, with both edges slightly curved and the outer surface of the vertical plate is wrapped in soft rubber (4) There are three ways to wrap it. First, the vertical plate of the hook (3) is placed in the mold for casting, then the dissolved rubber liquid is poured into the tool, the rubber is cooled, removed from the mold for casting, and then the soft rubber (4). And hook (3) were combined into one mass; Secondly, when making the soft rubber 4, first, by dissolving the dissolved rubber liquid to form a shape, and then again bonded to the vertical plate of the hook (3) to form a mass; Third, after dissolving the dissolved rubber liquid into the casting mold, the vertical plate of the hook 3 is put into the casting mold, and after cooling the rubber, the vertical plate is removed from the mold and the soft rubber ( 4) and the hook (3) was to be combined into a mass.

The soft rubber 4 described above has braking force and viscosity, which is an inherent property of the material. The material is made of natural or synthetic rubber, for example, PVC, TPR, TPU, TPE, PU, urethane rubber, silicon resin (silicon), resin, mixed rubber, etc., and has an elastic modulus of 20 to 80 The thickness of one layer is 0.1-5.0 mm. However, excessively sticky viscous material such as gum or glue is not suitable for use.

FIG. 6 is a longitudinal cross-sectional view of the anti-slip hook shown in FIG. 5. FIG. The soft rubber 4 enclosed the vertical plate of the hook 3 except that the front wall was not completely enclosed. In other words, the soft rubber 4 (see FIG. 7) enclosed the vertical plate by the inner layer 41, the both sides 42, and the bottom layer 43, but the outer layer did not completely surround the front wall surface. For this reason, the hole 31 was drilled in the front wall so that the magnet block 8 could be inserted (refer FIG. 8). When the magnet mass 8 is in contact with the non-slip hook 7 and the metal object to be contacted with each other, the magnet is attracted to each other due to the attraction of the magnet.

As shown in FIG. 9, the present embodiment differs from FIG. 6 in that the outer layer 44 of the soft rubber 4 not only completely covers the vertical plate of the hook 3, but also the inner layer 41 and the outer layer. (44) penetrates through the hole (31), thereby allowing the soft rubber (4) to be permanently fixed to the outer surface of the vertical plate of the hook (3).

10 is a state diagram of use of the anti-slip hook (7). When the non-slip hook 7 is caught by the to-be-measured object 51 at the arcuate edge, a slight viscous adhesive force is generated when the non-slip hook 7 comes into contact with the to-be-measured object. When the tape measure 2 is stretched laterally, the soft rubber 4 is pressed against the surface of the object to be measured, so that resistance due to adhesion is generated, and this resistance acts as a non-slip. In addition, the anti-slip claw 7 is not affected even when the tape measure 2 is shaken up and down (indicated by dashed lines) or when it swings from side to side. Moreover, the anti-slip hook 7 does not slip off even when the tape measure 2 is stretched to the inclined angle, so that the inclined angle is up to 45 degrees.

11 is also a state of use of the anti-slip hook (7). When the user surveys the bottom of the surveyed object upside down, the non-slip hook 7 is hooked under the arched survey point 52 of the surveyed object, and the tape measure 2 is caused by the soft rubber 4 It does not slip easily when it is shaken up and down (shown by dotted lines) in the pulling process, or shaken from side to side. This makes it possible to carry out surveying work, which required two people in the past (one grappling and one pulling a tape measure) alone.

Second Embodiment

As shown in Fig. 12, the non-slip piece 45 is extended below the vertical plate of the hook 3 so that the soft rubber 4 has an anti-slip effect even on the large arched corner or the large inclination angle of the object to be measured. To form, the shape of the non-slip piece 45 is preferably slightly rounded inwardly. The use process is as shown in the following figures, as shown in Figure 13, the anti-slip hook 7 is attached to the large arcuate measurement point 53 of the object to be measured due to the anti-slip piece (45). It is supposed to be attached. In Fig. 14, the anti-slip hook 7 is used in the inverted hook method so that the non-slip piece 45 adheres to the lower side of the arcuate survey point 52. Both of these figures show the property that the soft rubber 4 and the non-slip piece 45 adhere to the surface of the object to be measured so that the anti-slip hook 7 does not slip easily. In addition, Figure 15 and Figure 16 is a situation when the non-slip hook 7 is hanging on the surface of the spherical object 54 and the cylindrical object 55, can also achieve the anti-slip effect on the same principle. For this reason, when the non-slip piece 45 is used, it is possible to produce a very good anti-slip effect even for a survey point having a relatively large arced edge or inclined angle.

Third Embodiment

As shown in FIG. 17, recessed small recesses 46 having a concave shape are formed in the inner layer of the soft rubber 4, or as shown in FIG. 18, for preventing slipping in the inner layer of the soft rubber 4. Convex portions 47, or slip pattern is made. The small concave portions 46 described above give the soft rubber 4 a suction effect as if it is a sucker, and the anti-slip convex portions 47 increase the frictional resistance.

Fourth Embodiment

As shown in FIG. 19, the non-slip piece 48 is formed on the upper end of the soft rubber 4 which surrounds the outer surface of the vertical plate of the hook 3, which is described above. It has the same characteristics as the anti-slip piece 45.

In the embodiment shown in FIG. 20, in contrast with the embodiment shown in FIG. 19 described above, the support piece 32 extending to the upper end of the vertical plate of the hook 3 is placed inside the non-slip piece 49. This embodiment prevents the non-slip piece 49 from bending or bending under excessive force.

[Example 5]

In the embodiment shown in Fig. 21, the soft rubber 4 is made in a '-shape', so that a vertical inner layer 41 and a horizontal inner layer 41 'are formed, and the soft rubber 4 is hooked (3). It is attached together with the inner surface of the vertical plate and the bottom surface of the tape measure (2), and then fixed with rivets or bonded with a viscose.

[Sixth Embodiment]

In the embodiment shown in Fig. 22, the structure of the anti-slip claw 7 of another type of tape measure 10 is disassembled, which includes a tape measure 2, a hook 3 and a soft rubber 4 And the three units of the padded piece 6, which are assembled as shown in FIG.

The present embodiment is different from the anti-slip hook of Fig. 4 described above as follows. A slightly arcuate thin extension piece 34 is formed below the vertical plate 33 of the hook 3, and the soft rubber 4 is attached to the inner surface of the vertical plate 33 in the form of the extension piece 34, Produce a non-slip piece (45). Therefore, the claw 3 of the anti-slip claw 7 is a two-layer structure when observed in cross-sectional view. In addition, the soft rubber 4 may completely wrap the entire vertical plate 33 and the extension piece 34 in such a manner as to completely wrap (as shown in FIG. 27). In this case, the hook 3 may have a three-layer structure. do.

24 is a longitudinal cross-sectional view of the anti-slip hook of FIG. The vertical plate 33 of the hook 3 is made for holding, and the thin extension piece 34 has excellent bending strength, and the material serving as the skeleton of the non-slip piece 45 is this extension piece 34. Because of this, even under excessive force in the surveying process, it will not bend and break.

25 and 26 are state diagrams when the anti-slip claw 7 shown in FIG. 24 is mounted on the arcuate and spherical objects, respectively. The vertical plate 33 and the extension piece 34 of the hook 3 shown in the drawing are attached to the surface of the measurement object by the soft rubber 4 and the anti-slip piece 45, but the contact area is relatively large. The force is also relatively larger, thus increasing the adhesion and anti-slip effect. In addition, the hook (3) is bent in the form that was originally bent inward or outward, the extension piece 34 is not affected by the tension, even if deformed, the non-slip hook (7) is a measurement object Once apart, the extension piece 34 is reduced to its original shape. In addition, the tape measure (2) if the measurement proceeds only within the survey angle of about 45 degrees, so that the slip-proof hook (7) at any time does not slip off.

[Example 7]

As shown in FIG. 27, in consideration of the convenience in manufacturing, the soft rubber 4 completely surrounds the vertical plate 33 and the extension piece 34 of the hook 3, and the soft rubber ( A groove 401 is formed in the front wall of 4), and the cut groove is positioned between the vertical plate 33 and the extension piece 34. In addition, FIG. 28 illustrates a structure in which the protrusion 402 is extended below the incision groove 401.

Fig. 29 shows the state of use of Fig. 28. When the non-slip claw 7 is hooked up to the measurement point of the object to be measured, the soft rubber 4 is forced to cause a change in shape so that the crack of the incision groove 401 is removed. It is reduced in size, and further, a resistance action is caused to the protrusion 402 and the upper wall of the cutout 31, thereby sharing the tension applied to the extension piece 34 and preventing the elasticity of the soft rubber 4 from weakening. It allows you to.

As shown in FIG. 30, in order to facilitate the manufacture of the extension piece, the hook extension piece 35 according to the present embodiment was independently manufactured and then joined again with the vertical plate 33 of the hook 3. The extension piece 35 is a metal lead (thin piece piece) or a plastic elastic piece.

[Example 8]

31 and 32 are three-dimensional exploded views and assembly cross-sectional views of the anti-slip hook of another type of scroll tape measure. The non-slip hook 7 of the roll-shaped tape measure 10 shown in the drawings is different from those in FIGS. 1 and 22 as follows. The outer side of the hook (3) is surrounded by a layer of hard-shaped plastic bar (20) made of one layer, wrapped with rivets or viscose adhesive to fix. Combining the elastic extension piece 35 under the vertical plate of the protective rod 20, the protective rod 20 is fitted with a piece (6) centered on the tape measure (2), but fixed with rivets. Finally, the outer surface of the vertical plate and the extension piece 35 of the protective rod 20 is surrounded by a layer of soft rubber 4. Among the above-described contents, the protective rod 20 is easy to manufacture, and is easy to assemble in accordance with the tape measure 2 and the extension piece 35, and furthermore, the soft rubber 4 is easily attached to the outer surface and is loosened and dropped off. Do not work. In addition, an incision groove 401 and a protrusion 402 as shown in FIG. 28 may be provided on the front wall of the soft rubber 4.

[Example 9]

FIG. 33 is a three-dimensional exploded view of another kind of anti-slip hook, except that the present embodiment differs from the eighth embodiment shown in FIG. 31 described above. The anti-slip claw is made by making a recessed groove 21 at the front end of the tape measure 2, inserting the hook 3, and then placing the tape measure 2 on both shoulders of the vertical plate 33 (see FIG. 34) to connect. The front edge of the ring 7 is aligned with the front edge of the tape measure 2. In addition, when the magnet mass 8 fitted to the vertical plate 33 of the hook 3 comes into contact with the metal object to be measured, it can be attracted and fixed by magnetic force. In addition, the horizontal plate of the hook (3) has two oval holes (36) to insert the rivet 81 to form a rivet coupling with the tape measure (2) and the patch piece (6), the other side of the patch piece (6) The end was riveted to the tape measure (2) by another rivet (82) to be fixed.

Fig. 35 is a state diagram in which the non-slip claw 7 is caught by the measurement point of the object to be measured. When the tape measure 2 is pulled under tension, the extension 34 of the hook 3 changes from arcuate to vertical, at which point the hook 3 can move in the opposite direction under the force of a rivet 81 ) Moves in the oval hole 36, and finally allows the inner wall of the soft rubber 4 to fit snugly with the front edge of the tape measure 2. And since the scale of the front edge of the tape measure 2 is zero, after the inner wall of the soft rubber 4 touches the object to be measured, the survey point starts at scale 0, thus preventing errors in the measurement.

In the above description of the preferred embodiment of the present invention, the scope of the present invention is not limited only to this specific embodiment, those skilled in the art is appropriate within the scope described in the utility model registration claims of the present invention. It will be possible to change.

As described above, according to the anti-slip hook attached to the end of the roll-type tape measure according to the present invention, the object to be measured on the anti-slip hook by using a soft rubber wrapped around the outside of the vertical plate (that is, the end support portion) of the hook. The adhesive force between the soft rubber and the object being measured, and the direct pressure exerted on the soft rubber by the vertical plate of the anti-slip hook when the tape measure is stretched, ensures a firm bond between the soft rubber and the object being measured. Furthermore, it has an effect of preventing the phenomenon of slipping or slipping off. Furthermore, after the non-slip piece is formed to extend under the vertical plate with the soft rubber, the non-slip piece can be surveyed even for a relatively large arcuate or inclined angled object.

In addition, the outer surface of the vertical plate is surrounded by a protective rod, the extension piece is coupled to the lower side, and the soft rubber surrounds the vertical plate of the protective rod and the outer surface of the extension piece.
