Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a holding device that fits along the edge of a pavement block during the holding device.

Paving blocks are commonly used in landscape beautification to achieve both decorative and practical functions.

However, natural icing and thawing cycles on the ground on which the blocks are placed, as well as vehicle and pedestrian traffic, cause movement of the blocks. Such movement destroys both decorative and practical functions of the block.

Thus, the recognition that holding blocks in place is highly desirable is well established in the art.
Various edge support devices exist to hold the pavement block in place. Prior art edge support devices are difficult to assemble and lead to problems associated with the aforementioned problems.

A typical problem encountered with edge support devices is the fact that the various surfaces are defined by the edges of the pavement block for which a retaining mechanism is desired. In some cases, the edges of the pavement block may define a straight line to be supported. In other cases, the edges of the pavement block may define an arcuate (or curved) surface to the edge support device to be supported. By arc shape is meant a curved or irregularly shaped surface.

When the pavement surface is arc-shaped, it is difficult to adjust the holding mechanism to an appropriate shape. When it is straight, it is possible to hold the pavement block in place by a straight support mechanism. However, when different edges are defined, two completely separate mechanisms are required in the prior art to hold the pavement block in place. It is highly desirable to hold the pavement block in place with one type of device that can be easily modified at the work site. If this could be achieved, it would be easier to provide the necessary edge support material.

Also, the required length of the edge support device can create a problem. The longer the edge of the pavement block that needs support,
Achieving the desired proper placement of the edge support device is more difficult. In addition, as the paving block area extends,
Continuously, the edges can be arcuate, then straight, and then return to arcuate again. It is highly desirable to have one easily modifiable unit that provides the necessary edge support for any edge shape of the pavement block.

The long unit of the edge support device presents many difficulties. First, only a certain length of material is allowed to be transported on a highway. Second, handling long units presents difficulties at the work site. In addition, other transport issues may exist. For example, the assembly may not fit snugly into a truck or vehicle. Thus, long units create transport problems and handling difficulties at the work site.

Connecting multiple units of the edge support device to achieve the desired length to solve the long unit problem creates many other problems. Seams inherently create weakness in the device. The operation of the connection device at the work site also creates problems. Many different parts are needed for the connection. Special work is required to make all of these parts available. The strength of the seam is inversely proportional to the ease of connecting the units. Making the required connecting members available also creates problems.

It is difficult to hold the edge support in place.
The strength of the support must be maintained, and the support must be left in place even during the freeze / thaw cycle. The freeze / thaw cycle may also loosen the nail holding the support. It is desirable that a single unit achieve such retention. The assembly must be configured to avoid the above problems.

Nothing holds the holding device for the pavement block in place better than a good root system. It is important that the root tissue be able to lock into the holding device. Retention devices known in the prior art include such desired root interlockin.
g) does not allow.

Thus, it can be seen that there are a number of problems in achieving adequate support for a group of pavement blocks.

Description of the Presented Example The holding device for a pavement block of the present invention has a vertical plate for contacting the pavement block and various support points for the vertical plate. At a preselected point along the vertical plate is located a belt made of material perpendicular to it. Gusset members supported by boss members support the belt of material on the vertical plates. The boss members support the nails in the ground to help place the holding device for the pavement block in place until the root tissue (roos system) can develop so that the holding device is more tight and in place. Be prepared to drive through the member.

It is difficult to secure the nails in the holding device due to the lifting and vertical movement (freezing and refreezing of the land) that occurs at the underground freezing line. The problem of underground freezing lines is avoided by protrusions on the nail passing through the boss member when the nail is driven through the boss member and locked in the edge support. In this way, the holding device is placed in place until the root tissue has developed to ensure the placement in place. The nail is optimal for use in non-frost areas and can be used to place the holding device in place until the root tissue has developed.

A strip, a long member that extends the length of the vertical plate, caps the edge supports or individual strips. In this way, an opening is provided between the gusset member and the edge support through which grass and other plants can grow and support the edge support strip in place.

A male member suitable for locking one holding device to another is provided at the tab end of the holding device for the pavement block. The tab end cooperates with the female member at the other end of the retaining device when locking to one retaining device of the other retaining device. The holding device incorporates an integral stop device therein. A very desirable strength support is achieved. In this way, paving blocks of different lengths can be supported by long devices formed by using multiple holding devices.

If it is desired to form a bendable member,
The strip is cut across the trailing edge and, if required, a portion thereof is removed. Usually, simply cutting is sufficient. It is also possible to have a weak point in the long member strip. In this way, bending can be achieved concave or convex such that it extends along the curve formed by the pavement block.

It is also possible to incorporate a boss member for stacking the holding device. In this way, the transport of the plurality of holding devices is simplified.

Any suitable method may be used to make a holding device for the pavement block of the present invention. However, the unique shape of the device allows the use of plastic or synthetic resin injection molding to provide a robust device that can be used in an efficient manner. The construction and shaping of the tabs allows for highly efficient production and replication of the holding device. In this way, great advantages are obtained. Stacking bosses can be located at the mold knockout points and achieve the desired coupling and effective use of the holding device.

Referring now to FIGS. 1, 2 and 3, the holding device for the pavement block has a vertical plate 120. FIG. The vertical plate 120 is a long piece of flat material having a contact side 122 for contacting the pavement block and a support side 124 for receiving a support member 140 having a plurality of components at different points along the vertical surface 120. Support member 140 at preselected point along vertical plate 120
Is located. Each belt 142
Is substantially perpendicular to the vertical plate 120 at its bottom edge 126.

A trapezoidal cap 138 caps each end of the retaining device for the pavement block. Trapezoidal cap 138 is vertical plate 120
And the support member 140 are supported in such a relationship.

A gusset member 160 supported by a centrally located boss member 162 has a belt
Support 142. The boss member 162 is substantially parallel to the vertical plate 120 and provides for driving a nail 200 (shown in FIG. 14) into the ground to secure the retainer 100 in place. Since the boss member 162 is a hollow cylinder, the nail 200 penetrates the boss member 162.

A first slab 164 is located between the boss member 162 and the vertical plate 120 as an integral support for them. A second slab 166 is located on the opposite side of the boss member 162 from the first slab 164 and also supports the boss member 162. Preferably, first slab 164 and second slab 166 are trapezoidal to facilitate molding.

A capping band 144 covers the belt 142 with a cap. The second slab 166 is located near the capping strip 144. Both the belt 142 and the capping strip 144 are made of a flat material. The longitudinal axis of the capping strip 144 is substantially perpendicular to the longitudinal axis of each belt 142. In this way, a common plane is defined by the belt 142 and the capping strip 144. This common plane is substantially perpendicular to the plane defined by the vertical plate 120. In this way, the belt 142, the vertical plate 120 and the capping strip 144 provide a plurality of generally rectangular openings 148 for grass or other plants to grow therethrough and provide a retaining device for the pavement block. Work together to support proper placement.

FIG. 16 shows the holding device of the present invention in place for the paving stone 300. As can be seen, the contact side 122 of the vertical plate 120 contacts the paving stone 300 and holds the paving stone in place. A soil 302 is packed behind and supports the supporting side 124 of the vertical plate 120. Grass 304 has roots 306 and extends through openings 148 to provide support for soil 302. As can be seen, the opening 148 is formed by the vertical plate 120 in front.
Behind is defined by a capping strip 144.

Next, FIG. 3, FIG. 4, FIG. 6, FIG. 11, FIG.
Referring to FIG. 13, at the tab end 128 of the retaining device for the pavement block is located a male member 130 suitable for locking against other members. The tab end 128 engages the female member 132 at the receiving end 134 when locking one retention device 100 to another retention device.
In conjunction with imparting a highly desirable strength to the connection.
A trapezoidal cap 138 is located at each of the tab end 128 and the receiving end 134. In this situation, any suitable length can be formed by using multiple holding devices 100.
