Description

COVER
The objective of the invention is a cover, especially for a planting box comprising a framework intended for street trees, bushes and other corresponding plants.
Generally such covers, the so called earth gratings, are of steel-cast. The purpose of the gratings is primarily to cover the opening formed around the plant and thus also to protect the plant roots. Steel-cast gratings are expensive to manufacture. They are also very heavy, which puts high demands on their support and also makes them very difficult to handle. Steel-cast gratings are generally made of one piece, which further accentuates said disadvantages. The surface of the steel-cast grating is also slippery, which causes an extra risk especially to pedestrians.
The objective of this invention is to produce a cover that lacks the above mentioned disadvantages and which is simple to construct and to use. The objective is achieved with a cover which is mainly characterized in that the cover is formed of plate elements supported in a framework, which elements form an opening to receive the plant trunk or corresponding, and that the plate elements can be supported in relation to each other with additional support members.
The basic idea of the cover according to the invention is that the cover can easily be mounted and adapted to different surroundings. This is embodied so that the cover is formed of plate elements, which can easily be assembled around the plant and simultaneously supported in the underlying planting box and in each other.
The plate elements are favorably accommodated symmetrically around the opening to be formed, and the auxiliary support members intended for their mutual support is adapted in the edge zone of the opening. The support of the cover in the planting box framework is favorably embodied so that the upper edge of the framework is provided with a continuous or non-continuous groove or tongue encircling the framework, and the outer edges of the plate elements to be supported in the framework are provided with a tongue or groove to form the groove-tongue joint between the planting box framework and the plate elements.
The auxiliary support members are favorably formed of a beam construction to be supported in the planting box framework or of connecting bars joining the plate elements and attached to the plate elements with e.g. bolted joints.
To protect the plant trunk, the plate elements are favorably provided with at least one edge element adapted in the periphery of the opening formed. This can be implemented in several ways, e.g. by using one edge element, by providing each plate element with a separate edge element bordering to each plate element, or by placing the edge elements to accommodate in the area of at least two plate elements.
The plate elements are further favorably provided with slots and/or openings to secure the access of air and water.
For manufacturing, handling and durability reasons the plate elements, the auxiliary support elements and the edge elements are favorably of concrete, aerated concrete or other corresponding undecaying material.
The invention is described below more in detail with examples and with reference to the enclosed schematic drawings, in which
fig. 1 shows the cover according to the first form of embodiment of the invention. fig. 2 shows a cross section of the cover in fig. 1, fig. 3 shows the cover according to the second form of embodiment of the invention, fig. 4 shows a cross section of the cover in fig. 3, fig. 5 shows a modification of the cover in fig. 1, fig. 6 shows a cross section of the cover in fig. 5, fig. 7 shows the cover according to the third form of embodiment of the invention, fig. 8 shows a cross section of the cover in fig. 7 from the direction Y, fig. 9 shows a cross section of the cover in fig. 7 from the direction X, without edge elements, fig- 10 shows the adaption of the beam construction acting as auxiliary support members, fig. 11 shows the cover according the fourth form of embodiment of the invention, fig. 12 shows a cross section of the cover in fig. 11, fig- 13 presents an example of a planting box framework for covers according to figs. 1-4, and fig. 14 presents an example of a planting box framework for covers according to figs. 7-10.
The first form of embodiment of the cover shown in figs. 1 and 2 comprises four symmetrically adapted plate elements 2, which are supported from their outer edges in the planting box framework A. The plate elements 2 form in the center of the cover 1 a circular opening 3 intended for the receiving of the plant trunk or corresponding. The support of the outer edges of the plate elements 2 is arranged so that the outer edges 21 are provided with the tongue 22, accommodated in the groove Aa formed in the upper edge of the framework A. Each plate element 2 is further provided with a circular edge element 4 adapted around the opening 3 of the cover 1, which primarily is intended to protect the plant trunk. The edge elements 4 can be attached to the plate elements 2 with e.g. the bolted joint 5 presented in fig. 2. The plate elements 2 are also attached to each other with the same bolted joints 5, and two plate elements 2 are respectively connected to each other from below the cover 1 with a connecting bar 6 acting as an auxiliary support member, in which the bolted joints 5 are fixed. The second form of embodiment of the cover 101 shown in figs. 3 and 4 comprises eight plate elements 102 supported from their outer edges in the planting box framework A' . The plate elements 102 form in the center of the cover 101 a square opening 103. The support of the outer edges of the plate elements 102 is arranged so that the outer edges are provided with the tongue 122 adapted in the groove Aa' formed in the upper edge of the framework A' . In this solution the edge elements 104 are accommodated around the square opening 103, which elements are fixed to one plate element 102 with the above described bolted joints 105. The one end of the edge element 104 borders to the plate element 102 to which it is attached, and the opposite end of the edge element 104 protrudes from said plate element so that it comes on top of the adjacent plate element, whereby the edge element 104 simultaneously supports the plate elements 102 to each other from the edge of the opening 103 formed by them. The edge elements thus function as auxiliary support members support¬ ing the plate elements to each other. The framework A' is also .provided with beams 106 of the beam construction which comes under the plate elements 102 and in the edge of the opening 103 to support the plate elements in relation to each other.
Figs. 5 and 6 show a modification of the cover presented in figs. 1 and 2 using the same reference indications. The cover comprises four extra plate elements 2'' , supported by auxiliary beams 7 adapted in the framework A' ' , which beams are also provided with grooves Aa' ' receiving the plate element tongues.
The third form of embodiment of the cover 201 presented in figs. 7-10 comprises six symmetrically adapted plate elements 202, which from their outer edges are supported in the planting box framework B. The sector-shaped plate elements 102 form in the center of the circular cover 201 a circular opening 203, intended for the receiving of the plant trunk or corresponding. The support of the outer edges of the plate elements 202 is arranged so that the outer edges 221 are provided with the tongue 222 accommodated in groove Bb formed in the upper edge of the framework B. In this solution around the opening 203 are accommodated annular edge elements 204, the one end of which borders to the plate element 202 to which it is attached, and the opposite end of the edge element 204 protrudes from said plate element so that it comes on top of the adjacent plate element, whereby the edge element 204 simultaneously supports the plate elements 202 to each other from the edge of the opening 203 formed by them. The edge elements thus also function as auxiliary support elements supporting the plate elements to each other. The edge elements 204 can be attached to the plate elements 202 with bolted joints adapted in the area of the holes 205, as described above m connection with the other forms of embodiment, but has not been shown here.
The plate elements 202 are also supported m each other with the auxiliary support members 206, 207 and 208 The auxiliary support members comprise a beam construction supported in the planting box framework B as shown in figs 8-10. The beam construction comprises two across the framework extending base beams 106 supported in the framework B and adapted in the framework intermediate member layer C (the framework intermediate member layer C with its intermediate members Cc is more closely shown in fig 12) . On top of these base beams 106 is adapted the support layer comprising four support beams 106, 107, which are accommodated immediately under the plate elements 202 and around the opening 203 of the cover 201. The plate elements are thus safely supported at their outer edges as well as inner edges at the place of the opening. The connection bars attached with bolted joints presented in connection with the first form of embodiment, could naturally be used also in this embodiment (also below)
The fourth form of embodiment of the cover 301 shown in figs 11 and 12 comprises two sector-shaped plate elements 302 supported in the framework B of the annular planting box. The plate elements 302 form in the center of the cover 301 a circular opening 303. Around the opening 303 is adapted two annular edge elements 304, which are attached with bolted joints 305 in connection bars 306 provided under the plate elements as presented above. The edge elements are adapted so that they support the plate elements to each other from above the cover, and each edge element is attached to both plate elements.
