Description

An anchor for supporting an item on a substrate, and a method for providing heavy load bearing support on a stone wall by an anchor having an anchoring element that is configured to support a heavy load Field of invention

The present invention relates to a high-strength anchor, particularly suitable for directly supporting hospital rails as well as handrails, cabinets, bookcases, large-screen televisions, and other bulky items on walls, especially walls made of dry walls, or substrates. Upper, or on board a ship with a fiberglass or sheet metal substrate.

Background of the invention

A stone wall comprised of compressed powdered gypsum contained between thick sheets of paper or cardboard is one of the most common interior wall construction materials, particularly in the United States. It is easy to operate, erect, and has a good base for painting. The standard paper size is 4 inches x 8 inches and the thickness is 1/2 inch and 5/8 inch. However, it is a rather poor material as a support item, especially a heavy item, because of its poor structural strength and wrinkling when disturbed. In order to increase the support strength, the thickness of the stone wall is usually twice that of a standard hospital wall structure. However, stone walls, even if they are doubled in thickness, are still a rather poor support compared to cement, metal, wood, or other structural materials.

An ordinary structural body of an inner wall composed of a stone wall comprises a series of 2 inches x 4 inches in cross section, a lateral spacing of 16 inches, a wooden or metal frame column, and is connected to an outer wall. Directly behind the stone wall is a hollow with a depth of 3.75 inches, between the stone wall and the outer wall, with insulation placed in it, and wires, lead pipes, heating pipes and other lines are pulled into it. And hide it. It is best to connect the weight directly to the frame column, but this is not always possible logically because most of the wall spacing is an unsupported stone wall.

Many kinds of items are often hung on and supported directly on the wall. These items range from decorative static items such as paintings, mirrors (which may be light or heavy depending on the size of the painting or mirror) to heavy static items such as large screen televisions. Static items are not moved and are weights that do not change on the wall. However, many non-static items, in addition to their weight, also cause the support walls and structures to withstand the stresses of movement. Examples of non-static items include televisions, bookshelves, cabinets, and armrests on rotating or support members, particularly in hospitals. The support provided by the stone wall is problematic, especially in situations where it is impossible to add support directly to the frame column.

In response to the need to reliably secure and support articles on structural stone walls, a variety of fixed measures or anchors have been developed. These fasteners and anchors are categorized according to the weight they support. Very light weight fasteners include hooks, extension cord plugs, hook-in hooks, and drill-tail anchors with large threaded threads that are directly supported on the surface or thickness of the stone wall. One type of anchor that is provided with greater support strength is a hollow wall extension anchor. It is inserted into a pre-drilled space and extends behind the wall. These hollow wall anchors include conventional spring hinged toggle joints that are foldable for insertion with an inserted bolt and pop open behind a wall. Another common anchor is a Molly bolt anchor, which is tubular, with a cymbal inserted into the pre-drilled hole, and which is expanded by an inserted bolt, and the inserted bolt is expanded outwardly. When the foot is in contact with the wall, it is joined and pulled against the wall before the anchor. For example, TOGGLER manufactured by Mechanical Plastics The various plastic expansion anchors of the eccentric anchor are folded for insertion into the pre-drilled hole and placed under the expanded support position.

These hollow wall anchors can be inserted and the structural features that are opened for the expansion action are also limited in their support. Therefore, the hinged part of a set of ring bolts (which allows the anchor to be folded for insertion into the pre-drilled hole) and the flexible bendable metal of the Molly bolt (with the insertion of the bolts to pull back and expand the side feet) It is the same as the low shear strength of flexible plastic with plastic expansion anchors. These anchors are used to safely support medium weight, generally up to about 100 pounds, and typically require the use of sets of anchors.

Another grade of anchor is available with a high support strength design for hollow wall or stone wall structures. They include SNAPTOGGLE Anchor (also produced by Mechanical Plastics), which is provided with a non-hinged, solid metal trough support element that is bent longitudinally and inserted at the edge and then rotated back to its original axial position for engagement The rear of the wall. These anchors support hundreds of pounds of stone walls depending on the thickness of the wall. However, even with these capabilities, especially in non-static, high-stress, or high-weight support applications, there is still a need to increase the strength of the support, especially in the direction of the shear direction. However, due to the failure of such anchors in the support of the stone wall, the failure of the wall is generally a failure of the wall, so merely increasing the strength of the anchor is useless or only a little useful.

There are a number of factors, for example, increasing the size of the anchor limits the support due to the fastener or anchor. These additional factors include the size of the insertion aperture, the restricted area formed in the hollow behind the stone wall (which limits the size of an anchor that can be placed behind the wall), and the limited between the fixed element and the support wall. Interface area.

The rear of a stone wall is generally inaccessible and must be placed with an anchor through a pre-formed aperture in the stone wall to provide a fixed deployment on the rear or inaccessible side of the wall. This is an unclear situation. Larger anchors provide greater support strength, but these larger anchors also require larger insertion apertures. However, in stone walls, the formation of larger apertures weakens the wall, so the effect of using a stronger anchor is not achieved; thus limiting the width and size of the anchor that can be inserted.

In addition to the receptacles that limit the width of the anchor, the standard depth of 3.75 inches in the hollow between the stone wall and a supporting bottom wall also limits the length of the anchor that can be inserted into the aperture. The hinged, or flexible anchor with a longer length is weaker at the hinge point and has a flexible nature, which in turn reduces the support strength.

The strength of the stone wall as described above (i.e., the rupture limit depending on the thickness of the stone wall) is the most common limiting factor in determining the weight of a stone wall that can be safely supported, especially for heavy duty anchors. In order to increase the weight that the wall can support (in addition to the thickness of the wall that is not possible with current walls), it is necessary to increase the amount of wall area that supports the anchor or fixture, ie the weight of the dispersion, to allow the wall itself to support More weight. However, conventional anchors, such as Molly bolts and toggle bolt anchors, have been assembled to provide maximum expansion of the Molly bolts, as well as one for the toggle bolt anchors. The largest is spring loaded and articulated. In another Molly bolt anchor, an anchor specifically designed for the application of a grab bar includes an intermediate bar that is provided with a tapered skirt having free end metal feet, and the feet are at the periphery The upper portion is compressed, inserted into a pre-drilled aperture, and stretched and flared over the perimeter as it is inserted and engaged with the wall surface. Although the anchor's foot does not bend in a similar way to the Molly anchor, this anchor requires 1 The large insertion aperture of the inch is very expensive and has a weak hinge portion on the end where the legs are allowed to stretch. In addition, in order to avoid the flipping of the feet, the anchors cannot extend too far (i.e., over an angle of 45°).

Summary of invention

Accordingly, it is an object of the present invention to provide an inexpensive anchor that is adapted to support very heavy non-static gravity on a wall or other substrate, particularly a wall made of stone walls. One purpose of the anchor is to require only a small insertion hole that is larger than a conventional anchor. One purpose of the anchor is that the anchor can be expanded to support the substrate, such as a stone wall, significantly increasing the direct support interface as compared to conventional techniques.

Another object of the present invention is to provide an anchor having a support interface with a wall or substrate that spans the insertion aperture with a substantially complete weight bearing interface and extends in more than one linear direction across the insertion The aperture extends generally along its extension directly against the surface of the substrate.

Another object of the present invention is to provide an anchor having an anchoring element and being expandable, with more than two radial directions relative to the anchor receptacle, a support anchoring element is provided, wherein the anchor The fixture can be fully or partially expanded depending on any expansion disturbing the wall element.

Another object of the present invention is to provide an anchor as a substantially rigid component with or without a hinge, or a weakened flexible portion, and wherein the anchor is rotatably mounted on the wall surface Parallel, and adjacent one surface of the surface is expanded after supporting the stone wall.

Another object of the present invention is to provide a method and an anchor for performing the method, wherein the anchor member provided with a support member is first expanded with a first expansion after a wall or a substrate such as a stone wall A second expansion is then utilized to expand with another support member in a different direction relative to the substrate, while the weight received on the substrate is substantially supported by the expansion and support members.

In general, the invention includes a method of securing and an anchor for heavy duty gravity support on a substrate, particularly on a wall made of stone walls. The anchor has an anchoring element that is configured to support heavy and/or dynamic gravity on a wall having an inaccessible side. The method includes the following steps:

a) inserting an anchoring element of a very small configuration through an insertion hole in a wall or substrate, such as a wall made of stone walls;

b) expanding the anchoring element of the minimum size configuration with respect to a first direction of the jack;

c) then expanding the anchoring element in a second direction relative to the first direction, the first and second directions being separate and intersecting near the receptacle;

d) supporting the gravitational force against the substrate by the anchoring element expanding in the first and second directions.

The anchoring element assembly is configured to be insertable into an aperture formed in the substrate or wall for placement of the anchoring element for anchoring support to the inaccessible side. The anchoring element is further configured to have a very small cross-sectional configuration for insertion into a small receptacle (the diameter of the receptacle is most preferably slightly larger than the cross-sectional width of the anchoring element) and The wall is positioned and expanded on the inaccessible side, and is supported by gravity. The anchoring element further includes an element that is configured to complete a second expansion of the anchoring element for support against the inaccessible side of the wall. The anchoring element assembly is configured to expand and extend in at least two different directions, and the anchoring element has at least three, and preferably four, elements. Extending in a direction relative to the jack, at least a portion of the anchoring element spans the jack proximately. Preferably, the anchoring element is provided with a synergistic element that is engaged by an insertion bolt or screw during an erection to complete a rotational expansion extending into the second and plurality of directions. Preferably, portions of the anchoring element traverse the insertion aperture and extend in an equiangular direction relative to each other. In terms of extension, in a preferred configuration in four directions, the angles are all right angles. In a preferred embodiment, the anchoring elements are configured to complete at least a portion of the expansion in a direction of rotation on a plane parallel to the inaccessible side of the wall, and unless by a pilaster or Other - obstacle obstruction, this rotation expansion will only be blocked in the isometric direction and can no longer move. The extended multi-directional portions of the anchoring element each have a substantial length (preferably about 1.5 inches beyond the perimeter of the insertion aperture) to resist shear and pull outwardly with tension. The horizontal line angle (and 90°) position ensures a supported vector against the most common failure mode of the stone wall, ie the downward pulling force towards the bottom.

The above and other objects, features and advantages of the present invention will become more apparent from

Detailed description of the invention

In a preferred embodiment of the invention, the anchoring element is constructed of a metal socket channel element. The socket channel elements are provided with a structure adapted to be placed behind a wall of stone walls, suitable as a heavy gravity support element and having a small positioning profile. The individual channel structures having a U-shaped cross section are preferably provided with a flat bottom and vertical side skirts as they allow for the desired socket and have reinforced side skirt members. Conventional structures such as SNAPTOGGLE The anchoring member of the anchor can be used to initially place a plurality of channel elements behind the wall. However, it is important to understand the anchor placement mechanism, such as for SNAPTOGGLE The anchor positioning mechanism of the channel of the anchor is preferred because it is a well positioned channel, but other types of positioning elements can similarly be used with the anchoring element, such as the socket channel of the present invention. Suitable metals are metals that are often used in conjunction with anchoring channels, such as different grades of steel and stainless steel (when corrosion is a possible problem).

The socketed metal channel component of the anchoring element comprising the preferred embodiment of the anchor of the present invention comprises a bottom channel member, at least one top or upper channel member, and a threaded connection integrally formed with the upper and lower channel members element. In some embodiments, the connecting element is a separate element that is integrally formed with the channel members, while in other embodiments (such as a plastic anchoring element), the connecting element includes the upper and lower channel members One or a combination of two components.

The connecting element allows the top channel to be moved to a different, separate direction of extension, preferably by pivoting or rotating in a plane parallel to the wall. Under this pivoting, at least one of the channel members spans the insertion aperture and bears against the insertion aperture against the opposite surface of the inaccessible wall surface. The other channel member extends at an angle away from the first channel member and also bears against a surface of the inaccessible wall. Preferably, two or more of the channel members intersect each other at right angles across the insertion aperture, and all of the channel members bear directly against the wall. In this configuration, there are four anchoring elements that extend around the insertion hole and extend in different directions.

A straight-angled linear intersection between the two channel members is maximized by linearly extending the anchoring elements, respectively, and the support is evenly expanded. In the case where additional anchoring elements are provided, the angles of the intersections preferably provide a consistent radial arrangement of the anchoring elements. In a preferred embodiment, the actuation of the anchoring element to move or rotate is accomplished by the general steps required to use the anchoring member, for example, to support a bolt insertion to engage the threaded member of the connecting member. Instead of using a separate setup step. Although a separate setting, such as a rotating setting tool, is less preferred, it is still within the scope of the present invention. Preferably, a primary rupture element, or a frictional resistance element, is included in the plurality of channel elements. The resistance element assembly is configured to interfere with the insertion of the bolt first and to rotate a passage to a locked expansion position before the bolt is fully placed in the passage. In the locked position, the bolt is guided to overcome the resistance and continue to the full bolt positioning. The threaded connection element in the preferred embodiment engages the inserted bolt and provides resistance against external pull.

The separate sets of channel elements are configured to allow unobstructed rotational movement while maintaining a residual support structure and resisting deformation caused by gravity. Moreover, the plurality of channel elements are preferably assembled such that rotation or channel movement is accomplished when the rotating upper channel member is dropped into engagement with the inaccessible side of the stone wall. Since the upper or top channel member does not position against the wall before being completely rotated and lowered by a bolt, the movement is dragged by friction with the wall surface, substantially unobstructed in the direction of rotation. of. Both the bolt insertion rotation and the direction of rotation are in the standard clockwise spiral direction. When in the socketed position, the plurality of component groups in the bottom channel member are configured to lift the upper channel, and when the upper channel is partially or fully rotated or pivoted, the components are assembled to allow the upper channel Dropped on the connecting element, the jaws act to engage the channel member with the wall.

A pair of diagonally opposite sector ends of the upper or top channel rotate in a clockwise direction to allow it to rotate in a clockwise direction. In order to compensate for the removal of the material, the top channel member is preferably reinforced, such as with reinforcing ribs extending upwardly. However, the reinforcing ribs are configured and positioned to be fixed within the curvature of the insertion aperture to maintain a very small diameter of the insertion aperture.

In order to accommodate the additional thickness of the plurality of channels of the socket, the insertion aperture is minimally widened. Therefore, SNAPTOGGLE The one-inch inch insertion aperture required for the anchor is only increased to 3/4 inch to accommodate the plurality of channel anchors of the present invention provided with reinforced ribs. The size of the latter aperture is approximately the same as that required for conventional toggle bolt anchors, but can provide greater support. Conversely, heavy anchors for stone walls have a substantially required insertion aperture of more than one inch in diameter. In a plastic embodiment of the anchor of the present invention, the thickness of the wall of the anchor needs to be increased due to the nature of the plastic material itself. Thus, in the case of such anchors, it may be desirable to utilize an insertion hole of 7/8 inch to 1 inch diameter, but not as large as is required for conventional anchors.

Referring particularly to the drawings, as shown in Figure 1, the conventional hollow wall anchor 10 has three basic portions, a positioning member, an anchoring member, and a wall thickness adjusting member. The positioning element, such as the plastic locating leg 12, is connected by an insertion aperture in a wall and supports the metal channel anchoring element 20. The thickness of the wall provided with the aperture covering flange 36 and the adjustment member or cap 32 are deployed after placement of the anchoring element to complete the anchoring of the anchor. Figures 2A-D show how the components of the conventional anchor 10 can be used. The positioning legs 12 are slidably interconnected on the operating handle portion 56 and pivotally connected to the metal passages 20 in the holes 28 and 30. In Fig. 2A, the foot 12 is slidably moved to cause the metal channel 20 to pivot and in a very small insertion position wherein it longitudinally becomes extended with the foot 12 to allow the metal channel 20 to be inserted into the wall of the very small diameter. Hole 45 (applicable to 1/2 inch anchors on the market). After insertion through the insertion aperture 45, the foot is realigned in Figure 2B such that the metal channel 20 again becomes its lateral support position against the rear wall surface 46 for support. In Figure 2C, the adjustment member or cap 32 is moved along the foot 12 to engage the wall 40 adjacent the aperture 45 in which the adjustment member or cap is locked in place to clamp the wall 40. Between the channel 20 and the flange 36 of the adjustment element 32. The outwardly extending position of the foot member 12 is broken and a bolt 5 is guided and inserted into the cap 32 to threadably engage the thread 26 of the metal channel 20 to complete the fixed positioning of the anchor and A rack 7 is supported as shown in the 2D diagram.

In the embodiment of the anchor 100 of the present invention shown in Fig. 3, the positioning legs 12 are used similarly to the prior art shown in Figures 1 and 2A-D (other similar positioning may be used) Structure). The function and structure of the adjustment member or cap 33 are generally the same, but slightly larger, and are provided with a larger flange 33a that engages and covers the slightly larger insertion aperture required for the anchoring element 101. The anchor 100 of Fig. 3 differs the most from the conventional anchors in that the weight receives the anchoring element 101, while the sections 4-8B show the parts and components of the weight receiving anchoring element, and their variants. .

The anchoring element 101 of Fig. 3 is constructed of a structurally reinforced metal and its components are shown in Figures 4A, 4B and 4C, respectively. The anchoring element is constructed with a bottom support member 50 whose basic function can be matched to the channel member 20 of the conventional anchor 10 of Figure 1. A second top anchoring member 60 is a channel member that is slightly larger than the bottom member, and is sleeved on the bottom support member 50 and integrally formed therewith, and the member is pivoted by the member 70 (unclear, in the first Figure 4A shows a larger size) for a rotatable connection. The top and bottom members 60 and 50 have side skirts 61 and 51, respectively, and end skirts 66 and 56, the dimensions and configuration of which are nested together as shown in FIG. The segments 61a and 61b (61b which are not visible in the drawing) of the diagonally opposite side skirt portions 61 are removed so that the top member 60 can be clockwise as shown in the 5A-C diagram. Rotate rotationally (if a counterclockwise direction is desired, such as being affected by the proximity of the pilaster, optionally other diagonally opposite segments). Due to the removal of the segments, the area around the aperture 62 of the top member 60 is weakened and can withstand large gravitational folds. Therefore, as shown in Figs. 5A-C, the small lateral reinforcing ribs 68a and 68b are integrally formed with the top member 60. The bottoms of the remaining segments 61c and 61d (not visible to 61d) are provided with notch portions 63a and 63b (not visible), configured and sized to be rotationally rotated relative to the bottom member to the bottom member At a 90° position, the bottom flanges of the skirt members 51a and 51b (not visible to 51b) of the bottom member are engaged. The recess partially locks the top member in a desired support position, blocking further rotation and providing a resistance such that an insertion bolt is fully threaded. The invisible portions described above are generally symmetrical and identical to the visible portions.

When assembled, the pivoting metal element 70 is inserted into the aperture 62 of the metal top anchoring element 60 with the upper peripheral thick flange 75 resting against the perimeter of the aperture 62. The toothed portion 73 securely engages the wall of the aperture 62, and the height H of the toothed portion 73 is approximately equal to the engagement height aperture 62 of the aperture 62, i.e., the metal thickness of the top anchoring element 60. The lower portion 71 of the pivotal metal member 70 is provided with elongated holes 71a-d to allow a slight compression of the diameter of the lower portion 71 such that the lower portion 71 is fixed over the lip portion 72 of the pivotal metal member 70. The alignment aperture 52 of the bottom support member 50. The lip 72 returns to its original diameter and maintains the connection between the top and bottom anchoring member members 60 and 50 when the initial anchoring element is placed and inserted. The height H' of the lower perforated portion 71 is at least twice the thickness of the metal of the bottom member 50, so that when it is rotated to expand to the top anchoring member 60, it is placed and pulled downward. space. The top member 60 is initially longitudinally aligned with the bottom support member 50 and is spaced above the bottom support member 50 by the raised portions 50a, 50b in the spaced nesting relationship. The raised portions 50a, 50b are tapered and descend in height to cooperate with the rotation of the top member 60 such that the top member 60, as shown in Figures 5A-C, is positioned away from portions 50a and 50b. The location on the top. When the bolt 5 continues to be threaded into the pivotal metal member 70, the top member 60 is pulled downwardly about the flat portion 71 toward the bottom member 50, while the side members 60a and 61b of the top member 60 are guided directly to the wall 40. Make a supportive joint.

After the initial placement of the anchoring element 101 of the anchor 100 with the conventional anchoring method of the second A-B diagram, the metal channel anchoring element 20 is inserted longitudinally as shown in Figure 2A. The position is expanded to the expanded fixed position shown in Figure 2B, and the cap 33 is moved in the manner shown in Figure 2C to lock the anchoring element 101 against the wall 40. 5A-C shows an operational second expansion of the anchoring element 101 with the threaded insertion of a bolt 5. A resistance element 77 for a small cross member is welded or attached to the top side of the bolt hole 78 of the pivotal metal member 70. The other end of the crossbar member 77 remains unconnected. When the bolt end engages the resistance element 77 with the frictional force 5a, the unrestricted top member 60 provided with the pivotal metal member 70 is rotated in the bolt thread direction in the hole 52 of the bottom member 50 (the figure is relative to the bolt) Clock direction). Any of the bolt-advancing resistance elements, such as the expandable material in the threaded region 76, are similarly provided with sufficient resistance to resist the rotational expansion of the top member 60 by the bolts. In another embodiment (not shown), a tool is used to engage the pivoting member and rotate it with the bolt in a clockwise direction to expand. As clearly shown in Fig. 5A, the notches 63a and the notches 63b (not visible in the drawings) are moved against the opposite flanges of the side members 51a and 51b, respectively, and when the anchoring members 50 and 60 are at the 5B. And in the best right angle configuration of the 5C diagram, they interlock to prevent further rotational movement of the anchoring element 60. As the rotation of the anchoring element 60 ceases, the bolt 5 continues to be threaded into the threaded zone 76 and causes the resistance crossbar element 77 to continue to flex, completing the fixed deployment.

The anchoring elements 101' of Figures 6 and 7 are made of a strong engineering plastic such as polycarbonate or fiber-reinforced nylon, or other reinforced solid plastic material. Plastic anchors are especially useful in low-cost applications and applications where rust protection is required but stainless steel is too expensive or unsuitable for use. The anchoring elements comprise a corresponding top member 160 as shown in Figure 6A, and a bottom member 150 as shown in Figure 6B, but wherein the corresponding pivoting elements correspond to those shown in Figure 4A The structural elements are cooperatively integrated between the bottom and top members to form a connecting member 170.

The bottom member 150 includes a perforated connecting member 171 having an upper lip portion 172 and elongated holes 171a-d. As shown in cross section in Fig. 6C, the connecting member 171 can be compressed, inserted to engage, and engaged with a circular recess in the top member 160. The lip 172 engages into each of the circular recesses to maintain a connection between the top and bottom members when the anchoring element is inserted into a wall opening during bolt insertion. The circular recess has a wall having a height that is the same as the height of the surface 171 of the pivotal member, as shown in FIG. 4A, such that when the top member 160 is rotated away from the lift portions 150a and 150b, the pivoting member 171 is allowed. It is accommodated. Thereafter, the top member 160 is pulled downwardly, for example, by an insertion bolt (not shown) as the expanded configuration of FIG.

Resistance element 177 In the plastic embodiment, the resistance element 177 engages an inserted jaw as in the metal embodiment shown in Figures 5A-5C, but is more flexible due to its combination of plastics. Fully connected components. Another feature of the plastic combination is that additional reinforcing ribs are added to the top member. Since the connecting element is integrally formed with the top member 160 and the bottom member 150, bolt or bolt retaining threads 178 are molded into the upper projection of the top member 160. Alternatively, the top member 160 and the projections 162 are assembled with an inserted self-tapping screw plus threaded turns, for example, four or more threads to increase the support strength and delay the smoothing of the threads. Loose bolts.

An application of the armrest mounting is shown in Figs. 8A and 8B, in which the expansion anchoring member 101 is engaged with the wall 40 to the insertion hole 45 at the periphery of the insertion hole 45, and the armrest panel 200 is joined by the bolt 5. The insertion aperture can be as small as 3/4 of an inch, and the anchor member expansion elements of the top member 60 and the bottom member 50 can extend across the aperture in each linear direction up to Miles, the maximum strength of 500 miles on a 5/8 inch stone wall. The anchoring elements 101 extend in all directions to achieve maximum shear resistance and sandwich a wall region of approximately 4 inches in diameter with a four inch diameter armrest panel 200 (also shown in phantom in Figure 8B).

It is to be understood that the above-described drawings and examples are merely illustrative of the invention, and that the structure, configuration, and composition may be modified without departing from the scope of the invention as defined by the appended claims.
