    Disclosed is a fastener having a base portion and at least two anchor legs projecting from the base portion in the same general direction. At least one barb-like projection is disposed on at least one pair of the pairs of surfaces of the group comprising the remote surfaces on the outer sides of the legs and the proximate surfaces on the inner sides of the legs. Saddle surfaces begin at the one pair of surfaces and slant toward the other, opposite surfaces of the legs as they approach the free ends of the legs. Shoulder surfaces on at least the other of the pairs of surfaces of the group are generally opposite the saddle surfaces and are slanted toward the free ends of the legs, so that they form wedge-like cutting edges with the saddle surfaces at the end portions of the anchor legs.

    专利说明:

    The invention relates primarily to the field of construction and is intended to connect two wooden draws. Nails or glue are used to join the two wooden plates. When using nails, the nail head remains visible, and if it is deepened, it must be puttied. Sticking two wooden plates together with one another requires the pain of adhesion in relation to the adhesive, in both the two plates, the stretching properties of the wood species connected to each other, etc. In wall, ceiling, and floor shield elements, this problem increases even more, since the dressing must be selected, stored and processed with special attention. Both halves of the element in terms of dimensions, in particular, the thickness of both shields, their specific gravity, shrinkage parameters and expansion of the imprinted timber of the shields must be completely balanced, and the spacers (binding) between the shields must be free of any curved , It is well maintained and with a proper degree of humidity, in the absence of these requirements, the shield elements are boxed, i.e. become crooked. Therefore, the balance of the wood parts connected with each other is the main prerequisite for using the gluing technology. An example of the problems and difficulties of gluing technology are the door leafs for hollow doors, which are nothing more than closed with all-sided glue adhesive panel elements. Although these doors have a good aesthetic appearance and are standardized in their frames, the manufacturer can therefore purposefully select and purchase the binding, but they are always short of closing. In addition, with hollow doors, the sound absorption is quite small, since the cross section of the curtain is about 80%, and both door leafs are 20% of the door thickness, therefore the door leafs must be very thin. In addition, both door leaves should be the same in thickness. This also extends to wall plaques, the gluing of which is impossible due to the lack of balance, if both wooden shields have different thicknesses. . with
    In addition to bonding, gluing between the adjoining wooden parts should create a solid homogeneous compound, which in its turn is unsuitable from the point of view of noise absorption.
    In order to produce panel elements for walls, floors or ceilings, a large amount of wood of various sizes has been carefully stored for years, which requires large air-conditioned storage rooms and drying installations. In addition, air-conditioned processing plants are required. Gluing technology is thus very time consuming and expensive both in warehousing and processing technology. Glued wood panel elements cannot compete with elements made of inorganic materials.
    The nails for wood known hitherto, despite the tooth-shaped protrusions provided on their core, formed, for example, by means of corrugation, are not fixed enough in the wooden shield, i.e. it is easy to loosen or even with a relatively small so-called doughing effort that can completely break out of the panels. .
    A nail is known that contains a base part with two protruding anchor legs 8 in one direction, having piA-like protrusions on the inner sides and cutting edges at the ends formed by simm (eetrically arranged inclined surfaces 1.
    However, this nail does not reliably connect wood parts, since the jagged protrusions can be pulled out of the connected parts during operation.
    Also known is a nail with two anchor legs protruding from the common base part, located mirror-symmetrically relative to each other and having sawtooth-shaped protrusions and opposite edges on free-end sides formed by inclined surfaces of various lengths. The nail is made of resilient steel and is intended to join a wood piece with a metal one. The presence of inclined surfaces on the anchor feet XX creates a deviation in opposite directions when driving a nail, thereby increasing the strength of the joint 12.
    However, due to the fact that the nail is made of elastic steel and the sawtooth protrusions and elongated inclined surfaces spread out on the same side of the anchor legs, the reliability of the connection of the wooden parts is insufficient, since the anchor legs deviate in the direction opposite to the introduction of the sawtooth projections into the material of the parts to be connected, and the tendency of the legs to resiliently return to their original position eliminates the hook-like grip of the material of the joined parts by the legs.
    The purpose of the invention is to increase the reliability of fixing the nail in the joined wooden parts.
    This goal is achieved by the fact that in a nail containing anchor legs protruding from a common base part with sawtooth protrusions and cutting edges with inclined surfaces of different lengths on free ends, arranged pairwise mirror-symmetrically one relative to the other, sawtooth protrusions are located on each leg from the side the inclined surface of the cutting edge of a smaller length, while the nail is made of aluminum.
    In addition, the anchor feet can be arranged in pairs one against the other and directed in opposite directions.
    The nail can be made in the form of an H letter with two pairs of anchoring legs located one against the other, located at both ends of the base part.
    The base 4actb can be made in the form of a tape with at least two pairs of one antivirus Pawns of the other.
    The tape-shaped base part can be equipped with holders J-o6t a3HOFO profile and secured by ya (they have clapper cams, while the other part of the base part is located in a counter section one of which is in front of each other in the right param- age of parashaft, and a paratrooper is placed in the rear part of the baseline. the end of the base part is O-shaped.
    The base part of the nail can be made in the form of a tape, curved across the width through equal distances in the form of a trapezium with the formation of a zigzag, while the equal part of the base part contains several pairs of anchor legs, and the ribbon-like base part is flanged twice across the width pairs of longitudinal anchor tabs.
    The head can be made in the form of a figure of rotation, and the anchor feet have the shape of circular segments arranged around the circumference.
    The sawtooth protrusions, elongated and short inclined surfaces, and also the cutting edges can be located perpendicular to the longitudinal axis of the base part. Or. Saw-shaped protrusions, elongated and short inclined surfaces, as well as cutting edges can be located in the longitudinal direction along the edge of the ribbon-like base part. FIG. 1 shows an H-shaped nail in perspective view / in FIG. 2, the end portion of one of the anchoring feet of the nail in the form of a tear in FIG. 1 on an enlarged scale; in fig. 3 nail, the basic part of which in the form of a partition is made in the form of a tape and on each of its both longitudinal sides is provided with corresponding two pairs of opposing one another anchor legs in axon metry; in fig. 4 shows a nail in Fig. 3, after pressing its anchor leg into the shield and the tie in the cross section of a part of the shield element; in fig. 5 — nails that are clamped on a J-shaped profile serving as a nail holder, in axonometer in FIG. 6 - a nail holder with a nail clamped on it in FIG. 5 and two wooden shields before pressing the shield elements of the anchor feet into both shields in cross section; in fig. 7 - a nail holder with a socket in FIG. B — after pressing anchor pads into both wooden shields in cross section; in fig. 8 is a spatial image of a nail with a basic part in the form of a tape with a zigzag curved along trapeziums and in the longitudinal direction of which the anchor legs are arranged in pairs one above the other; in Fig. 9, a cross section of a nail, which with its base part can be inserted into an extruded profile and has protrusions facing each other, and also inclined surfaces located on the outer sides of its two anchoring planks in the direction of their free ends . 10 is a spatial image of a nail, which is made in the form of a body of rotation and on the periphery of which the anchoring legs are designed as ring segments; in Fig.11 spatial image of the H-shaped nail with additional protrusions in the form of reverse teeth. FIG. 1. Represents a nail of a tree, made in the form of an H-shape. The perimeter-shaped base part 1 of the nail is provided with two pairs of anchor legs 2, which resist in pairs one and two pairs and depart from the base part 1 in opposite directions. The base part 1 of the nail thus forms both of them extending from a right angle down and two protruding, also at right angles upward, in pairs following one after another by anchor feet 2, a nail shape corresponding to a large letter N. Both pairs of anchor feet 2, respectively, on the opposite sides of the feet, i.e. in this case: ae on the outer sides facing one another are filled with protrusions 3 in the form of counter teeth, and on the inner sides facing one another are provided with elongated inclined surfaces 4 which diverge in the direction of the free ends of the rods, which together with two the outer sides of both aperture legs 2 converging in the direction of the free ends with short inclined surfaces 5 cutting edges 6 and, together with two at least approximately parallel to each other, the outer surfaces E 7 at the free ends of the two anchor lapok.2, -by a wedge in cross section an end portion 8 of the anchoring foot 2 (FIG. 2). The 4, 5, and 7 wedges formed by the surfaces. The end portions 8, which serve as the inserted parts of the nail, must be made clean and smooth, so that, when pressing or nailing, the extruded anchor foot 2 is not crushed but, on the contrary, if possible, without resistance, slid along it, since the compaction of the wood, at least, makes it very difficult for the nail to be embedded in the material of the binding board, if it does not make it impossible. In order to ensure the sharpness of the cutting edge b and the same design of respectively pairwise divergent inclined surfaces 5 on both pairs of anchor legs 2, inclined surfaces 5 are formed / for example, by means of a cutter, even before cutting the extruded profile of aluminum, from which nails are made, i.e. ; even before cutting, forming separate nails with a piece of extruded profile. The anchoring feet 2 are made in pairs, mirror relative to one another. FIG. 2 shows, as a cut-out of FIG. 1, the free end portion of one of the four anchor legs 2 of an H-shaped nail (in FIG. 1, the anterior, protruding upward anchor foot 2), also in spatial form, but on an enlarged scale. It is clear from FIG. 2 that the inclined surface 5 is relatively narrow, the adjacent smooth, smooth outer surface 7, as well as the protrusions in the form of opposite teeth 3 below are placed on the outer surface of the anchor tab 2, whereas the inclined surface 4, which is significantly more than the inclined surface 5, i.e. passes much deeper than the surface 5 down in the direction of the base part of the 1 H-shaped nail, placed on the inner side of the anchor foot (figure 1). Depending on which height in height, i.e. As the sloping surface 5 on the free end of the anchor tab 2 is deeply milled, its size is differently reduced, as shown in Figure 2 by dashed lines. In this connection, the process of insertion of the anchor foot 2 or the entire nail can be controlled (Fig. 4 and 3 or Fig. 7 and 6} depending on the density or hardness of the shield material. From Fig. 2 it also follows that the milled surface 5 with a much larger inclined surface 4, in cross section, forms a wedge shape of the end portion of the free end of the anchor foot 2, a straight, sharp cutting edge 6, which is valid for any of the four nail anchor legs in figure 1. Three, 4.5, 7 and mutual position like their races The position to the protrusions 3, as well as the cutting edge 6 formed by both surfaces 4 and 5, exist in all other examples of the nail, i.e. also in the anchor tab 2 of FIG. 8, 9 or 10.
    FIG. 3 shows a nail in which the base part 1 is formed in the form of a tape and on each of the longitudinal sides of which is provided with two napeiMH opposing anchor legs 2 as a whole so that in the zone of both ends of the base part in the form of a partition 1 one H is formed the shaped part of the nail, which in terms of location, shape and pattern of action fully corresponds to the H-shaped nail in FIG. 1. The nail in FIG. 3 thus has a total of eight anchor feet 2, which in this case are the same in shape, size and size with each other, with the shape of the entire nail relative to both main axes of the nails passing through the base part 1 of the nail is strictly axisymmetric. This axisymmetric nail design exists on the nail in FIG. 1. The nail in FIG. 3 also represents a segment of an extruded profile, which is preferably made of aluminum.
    FIG. 4 shows in cross-section the nail of FIG. 3 after it is pressed into the wooden shield 9 with one side and into the wooden binding 10 with the other side. Now, the opposing anchor legs 2 are each of four pairs, unlike FIG. 3, where they are still straight and parallel to each other, curved towards the free ends of the legs, i.e. pairwise apart from one another. When inserting anchor feet 2 into a wooden shield 9
    or into the wrap 10 each of the four anchor legs 2, in connection with the inclination provided thereon; by their surfaces 4, they in pairs move apart in pairs from one another, while at the same time as the shape changes, they bend outwards and their natural ends move away from one another. This leads, in combination with the protrusions 3 made in this case in the form of embedded zubi saws, to an extremely deep, strong and durable connection between the nails and the wood shield 9 or tie 10. For when tearing forces occur on the nail, they also cut into Moreover, the sawtooth protrusions 3 firmly hooked into the wood into the wood and the stronger, the greater the corresponding wresting force. The thickness of the anchor legs 2 correspond to the strength properties of the original material for nail (aluminum), which, in combination with the formed between the surfaces 4 on the one hand, and the surfaces 5 and 7, on the other hand, the wedge angle 8 and the profile of the protrusions 3 with counter teeth, Taking into account the structure and strength of the wood of the tie or the material of the shield, the desired divergence of the anchor legs corresponding to one another is really occurring when the tongue or shield is inserted into the wood.
    It is very important for the immaculate, i. a predetermined correct change in the shape of the nail in the shield 9 or in the wood of the trim 10 so that the material of these two parts at the beginning of the pressing process is primarily pierced perpendicularly to their end surfaces, which is provided by the anchor legs inclined to the opposite side of the inclined surfaces 4 relatively narrow inclined surfaces 5 (Fig. 2 and the formation by both surfaces of
    4 and 5 of the cutting edge 6 as it follows from FIG. 2, as well as in the anchor rod 2 of the nail of FIGS. 8, 9 and 10.
    If these external inclined surfaces 5 were absent on the anchor foot 2, then the cutting edge 6 would be distorted before being inserted into the material, i.e. thus, it would lose the sharpness necessary to penetrate the outer surfaces of the shield 9 or binding 10, which would often make the pressing process impossible, and could even result in breaking off the anchor foot 2 from the base 1 (Fig. 3).
    If this inclined surface

    E 10 into the material without curving, cutting edge 6, blunting or scaling to the side, namely, so deeply, until the entire inclined surface completely enters shield 9 or backlash 10. Only then does it penetrate further into the material The anchor foot begins a predetermined process of changing the shape, which is caused by increasing, in this case, diverging forces on significantly larger, inclined surfaces located inside the inclined surfaces of 4 pairs of anchor legs 2. Located on the inner sides of the pairs of anchor legs 2 extremely high, inclined surfaces 4, diverging in the direction of the free ends of the anchoring lugs 2, or components of the pressing pressures applied to these surfaces just during the subsequent introduction of the nails into the material, unwind the anchoring legs 2 pairwise opposing each other . At the same time, the insertion of anchor lacquer 2 into the material of the shield or into the wood of the wall due to sharp cutting hooks 6, which are formed by smooth inclined surfaces 4 and inclined surfaces 5 at the free ends of the claws 2, is greatly simplified so that it cannot the wood is compressed when inserting the anchor feet 2 and therefore the forces necessary for pressing the nail into the shield 9 or the binding 10 remain with within certain limits, i.e. Do not increase excessively. Using the pressing processes, the longitudinally extending main parts of the surface of the web partition 1 abut against the opposite face surfaces of the shield 9 and the tie 10 (Fig. 4). FIG. 5 wood nails are clamped on shelves 11 of an L-shaped profile 12 bent in blue, which is made of aluminum, serves in this case also as a holder and at the same time as a disconnection element for setting the distance and joining two shields for the shield element, as This slide is from FIG. 7. Here, two Y-shaped parts 13 of the nail are connected to each other by means of the basic part 1 of the nail, forming a ribbon-like element 2 (.fig. 6 and 7). Both and-shaped parts 13 of the nail correspond in design to the upper or lower half of the nail in Fig. 1, while the basic part 1 of the nail in Fig. 1 is divided along the length and the I-shaped parts of the nail thus formed could be regarded as connected one with another and located at a distance from one another with the help of a tape-shaped connecting part. The nails are thus spread on a 3-shaped profile that they, with their ribbon-like base parts 1, are clamped on it alternately on one side and the other. FIG. 6 shows in cross-section a wavy 3-shaped profile 12 with a nail clamped on it before storing the nail into two wooden shields of 9 different thicknesses. Basically, the i-shaped base part 1 of the nail has clamping lugs 14, which cover the corresponding shelf 11 of the 3-shaped profile 12 from the side and thus provide. It provides a secure connection between the nail and the L-shaped profile 12. A 3-shaped profile 12 equipped with nails is installed between both shields 9, and due to the wavy shape, the profile has good stability. On . Figure 7 shows the outlines of the system in Figure 6 after pressing the nails into the two shields 9. The anchoring feet 2 are separated from each other in pairs, as already shown in FIG. By means of a press, the nails were pressed from the inner sides of the wood shields 9. In FIG. 8 shows in a spatial image a nail with a curved zigzag in the form of a trapezoid and a screw-shaped basic part 1. A ribbon-like basis part 1, respectively, between two adjacent pairs of anchor legs 2, is bent double-shaped as a trapezoid in different directions, respectively, across the entire width of the tape and thus as one piece zigzag bent in both directions. Here, the corresponding interconnected anchor legs 2 are arranged one behind the other in pairs in planes parallel to one another of the ribbon-like base part 1. The inclined planes 4 are located here in contrast to the arrangement of the nail in FIG. 5-7 in planes that run at an angle of 90 across the middle longitudinal axis of the ribbon-like base part 1 of the nail. The above is also characteristic of those not shown in FIG. 8 for the clarity of inclined surfaces (5 in Fig. 2), sawtooth protrusions 3, outer surfaces 7 on the free ends of the anchor rods 2, as well as for the cutting edges 6. Pressing in and changing the shape of the nails occurs exactly as previously explained. based on FIG. 6 or 7 or even earlier in FIG. 4. FIG. Figure 9 shows a nail for a tree, which by its base part 1 can be pushed into the extruded profile 15 of aluminium serving as a panel. In contrast to FIGS. 1-8, in this case, the protrusions 3 in the form of all three teeth are located on the internal torons of both opposite anchor legs 2, i.e. here they are in contrast to FIG. 1-8 face one another. Accordingly, here the inclined surfaces 4, which form the cutting edges 6, are placed on the outer sides of both anchor legs 2, so ijaK they are turned to the other. from each other, what is the convergence of the tsy to the free ends of the lapo ie do not diverge, as was the case in FIG. 1-8. Accordingly, here the narrow inclined surfaces 5 are on the inner sides of the two anchor legs 2 facing one another, and they diverge in the direction towards the free ends of the anchor legs 2, accordingly, both of the anchor legs 2 do not dissolve the nail when pressing in one from the other, and vice versa, after inserting the end surfaces 5 into the wood one against another, and describing the steep-shaped trajectories directed inside one to the other in the direction of the arrows and the free ends of the legs are also bent inward one to the other. The hooking effect is basically the same as in the pairs of anchor feet 2 of the examples of FIG. 1-8. FIG. 10 shows a nail, which is made in the form of a rotating body in the form of a glass, on the periphery of which the anchoring feet 2 are placed in the form of collar segments, with the round bottom of the glass forming the base part 1 of the nail. The nail can be made, for example, as a shaped part on an automatic longitudinal turning machine from a solid round aluminum bar. The body of rotation of the nail may also be completely hollow in the direction of its longitudinal axis, i.e. It can be made of aluminum tube. The slots 16 are milled radially in the Cylindrical collar nail, while the remaining ring segments form anchor legs 2. Segmental anchor legs 2 are also provided with inclined surfaces 4 on their inner sides, and inclined surfaces with ultrasound on their outer sides 5, which form cutting edges 6, as well as their outer sides with protrusions 3 in the form of corrugations or counter teeth, all this work can certainly be performed before milling the radial slots 16, as purely turning works on the face but-cutting automatic lathes. If a nail for a tree cuts into the tunnel, then its anchoring feet 2 streamer 1c separate from one another in the form of a bouquet, as shown in figure 10 by. A nail may, for example, be used for a point-to-point connection of heavy parts both on roofs and on walls. For this, it is sufficient in this case to have a simple nail in the form of a glass whose height corresponds to} half the height of the nail in FIG. in which the bottom of the glass forms the base part 1. in FIG. 11 shows an H-shaped nail for wood in accordance with FIG. 1, both pairs of anchor legs 2 of which are additionally provided on their inner sides with protrusions J in the form of counter teeth, which are adjacent to inclined surfaces 4. Through these internal, counter teeth 3 when embedded nail into natural wood (especially soft wood) which is respectively compressed between both legs 2, the resistance to pulling out the nail increases even more. If in the embodiments of FIG. 5-7 nails were hung on a wavy, tape-shaped 3-shaped profile 12, in the design of FIG. 8 nail for wood itself is made in the form of a tape. In both forms of the nail for the tree, both shields 9 (in Figures 6 and 7) were mounted with a tape partition 12 at a distance from each other and firmly connected to each other. These tape partitions are an ideal aid to the production of shield elements bypassing the lability used so far in bonding technology and their high cost, in particular, without any damage to the external surfaces on visible surfaces. In this case, the web partition takes over the function of maintaining the straightness of the shield element, the shields of which, for example, canvases of hollow doors, can no longer be jarred, as is constantly the case with the gluing technology. Therefore, it is now without a problem to assemble shields of various thicknesses into shield elements, which, until now, using conventional adhesive technology due to the lack of sound absorption at that time, was impossible. Now there are significant opportunities for better sound absorption due to the new technology using nails. Since this new technology eliminated the high costs of air-conditioned warehousing and also heavy processing using very expensive gluing presses, the panel element will now be much cheaper / so for the first time in the price struggle against conventional elements from inorganic materials it will be competitive. Together with the well-known advantages of wood as a building material, it is not least important to note the aesthetic aspect - be it only in the production of panel elements for floors, ceilings or walls. With help, the proposed nail for wood also opens up a whole range of new technologies like for example, the application of solid wood, aluminum or plastic panels (Fig. 9) on boards or elements, the manufacture of flooring elements with finished flooring and;: 1and finished ceilings or, for example, it is possible Point attachment for heavy objects on ceilings or walls. Instead of pressing nails into wood, in special cases they can also be clogged. Instead of supplying the ribbon-like base parts of a nail for a tree along both longitudinal edges with anchor legs (Fig. 8), they could also be provided only on one longitudinal edge, except for measures for the ceiling-mounted ceiling elements. The invention is also not limited to the exemplary embodiments shown in the drawing, and the details of the execution could vary within the scope of the invention. Claim 1. A nail containing anchor legs protruding from a common base part with sawn-shaped protrusions and p cutting edges with inclined surfaces of different lengths on free ends arranged in pairs, mirror-symmetrically relative to each other, is different from that increasing the reliability of its fastening when joining wooden parts, sawtooth protrusions are located on each tab on the side of the inclined surface of the cutting edge of a shorter length, while the nail is made of aluminum.
