DETAILED DESCRIPTION

[0020] In the context of the present solution socket may be a post socket. the socket may additionally include a ground engaging portion, such as a wedge. The socket may be a ground anchor or an upper part of a ground anchor. The socket may be driven vertically to ground to hold a post. The post may be a wooden post. The post may be a fence post or any other vertically erectable element. Horizontal direction of the socket may correspond to the width in x and y direction of the post that is arranged into the socket.

[0021] Current socket solutions for holding a post have one or more holes on the sides of the socket. Such holes may be manufactured if the socket material is thick enough. With thinner sheets, the holes on the sides and the length of the sides between edges of the corners allow the socket to lose its shape thus making it impossible to securely install the post. With the proposed approach, thinner sheets may be used, because instead of holes sacrificing the stiffness, an additional edge is formed on two or more sides of the socket (see FIGS. 1-4). These edges form the flanges. The assembly of the socket from two or more flange forming parts thus shortens the length of the sides between edges. The flanges support the structure as additional corner-like structures. Therefore, thinner sheets may be used to assemble the socket. The socket structure is reinforced by introducing two or more additional edges, flange corners, to the socket. With the method of this disclosure the thickness of the metal sheet may be less than 2 mm, for example 1.5-2.0 mm.

[0022] Current socket solutions for holding a post have one or more flanged holes in the sides of the socket. If the holes are elongated to the whole height of the socket wall, the length of the hole defines the height of the socket. One aspect of the presented socket is that the flange extends from the base of the socket to top of the socket. Therefore, for two sockets with the same height, the presented socket has flanges that support the post inserted into the socket for its entire height. This is especially important at the top end of the socket which often receives forces delivered from the post, when in use. Because the socket without flanges cannot have holes at the top end of the socket, it fails to provide such top end support. Even if the holes on a traditional socket were circular, the same top end support problem remains.

[0023] The flange extends the whole height of the socket. The width of the socket is preferably 10-15 mm. This improves the grip of a post to the socket. Because the flanges extend to the top end of the socket, they stabilize the post by preventing any gap to form between the post and top end of the socket. Because the post is often tall and only fixed to the ground, lots of stress or strain is targeted on a post-socket combination. Strain or momentum may be caused be, for example, cattle hitting a post, a post having hinges for a gate that opens, or a person leaning on a post. Any gap between the top end of the socket and the post may allow strain or momentum to cause movement in the post-socket combination and loosen the post from the socket.

[0024] The straight walls of the presented socket are not only aesthetically pleasing, the walls enable the socket to be installed with any of the walls facing the visible side during installation. The installation is easier, because one does not have to take care of the orientation of the installation. Furthermore, straight walls are safer because they don't have holes with sharp cut borders. Such borders may cause injuries and/or tear clothes.

[0025] Because there are no openings on any of the sides of the presented socket, water is prevented from entering the socket from the sides. Therefore, the socket is more resistant towards damages to the post by water, and especially ice. Should water enter the socket, openings are arranged to the base of the socket to enable exit of the water.

[0026] FIG. 1 is a schematic illustration of an embodiment on the assembly of the socket 100 assembled from two wall parts 101, 102 and a socket base 105. Openings 106 may be arranged to the socket base 105. FIG. 2 is a schematic illustration of an embodiment on the assembly of the socket 200 assembled from four wall parts 201, 202, 203, 204 and a socket base 205. Openings 206 may be arranged to the socket base 205.

[0027] Each of the parts 101, 102, 201, 202, 203, 204 is made from metal, for example zinc-coated steel, by bending or curving the part about vertical axis into an angle corresponding to the respective angle of the post. Commonly, the post material is a rectangular wood post and thus the bending angle of the part is about 90 degrees.

[0028] Each part 101, 102, 201, 202, 203, 204 is bent about vertical axis to form at least one corner of the wall. When bent vertically, each of the parts extend to at least two horizontal directions. Each of the angles between the horizontal dimensions correspond to the respective angles of the post intended to be positioned in the socket that is formed from the parts. Each of the angles between the horizontal dimensions may be 90 degrees. The vertical dimension may be the gravitational direction. The horizontal direction may orthogonal to the vertical direction.

[0029] Free ends are formed on both sides of the vertically bent angle of the part 101, 102, 201, 202, 203, 204. The free ends of the part 101, 102, 201, 202, 203, 204 are arranged to extend 20-80% of the total wall width in horizontal direction The inner diameter of the total wall width 100% may match approximately the width of the post. Parts 101, 102, 201, 202, 203, 204 are bent such that when connected they form a rectangular opening with the inner diameter of the opening sufficiently wide to receive the post.

[0030] One free end of the part 101, 102, 201, 202, 203, 204 is further bent about vertical axis to form a flange 107, 207. The bending is made to the same direction as the first bend so that the flange 107, 207 is formed towards to post receiving inner section of the socket.

[0031] Flanges 107, 207 on the inside of the anchor compensate for differences in the post size. Additionally, if the flanges 107, 207 tightly fit or even penetrate the surface of the post, they may be used to fasten the post without any additional or external fastening means.

[0032] If the socket is manufactured from two parts (FIG. 1), the first part 101 has one angle and one flange 107, and the second part 102 has three angles and one flange 107. The inner diameter of the bending is made such that the post fits inside the bended parts 101, 102, when the parts have been connected. The unbent free end of one part 101 is connected to a root of the flange 107 of another part 102 and the unbent free end of one part 102 is connected to a root of the flange 107 of another part 101. Socket base 105 is connected to the ground facing bottom of the connected parts 101, 102. The connection may be a welded connection.

[0033] If the socket is manufactured from four parts (FIG. 2), all the parts 201, 202, 203, 204 have one angle and one flange 207. The inner diameter of the bending is made such that the post fits inside the bended parts 201, 202, 203, 204, when the parts have been connected. The unbent free end of one part 201, 202, 203, 204 is connected to the root of the flange 207 of a neighbouring part 204, 203, 202, 201 and the unbent free end of one part 204, 203, 202, 201 is connected to a root of the flange 207 of a neighbouring part 201, 202, 203, 204. Socket base 205 is connected to the ground facing bottom of the connected parts 201, 202, 203, 204. The connection may be a welded connection.

[0034] The socket base 105, 205 may be a stopper for the post. The openings 106, 206 in the socket base 105, 205 allow water passage through the socket. Socket base 105, 205 openings 106, 206 may have flanges to enable tighter attachment of the posts. Additionally, the socket may be attached to rigid surface through the openings 106, 206 using additional fastening means. The rigid surface may be, for example, a concrete surface or a rock surface that cannot be penetrated by a wedge or a ground engaging portion.

[0035] FIG. 3 is a schematic illustration of an embodiment on the assembly of the socket 300 with a post P inserted into the assembled socket. The socket may have been assembled from two 301, 302 or more wall parts 301, 302, 303, 304. Dashed lines indicate the location of the visible flanges 307.

[0036] FIG. 4A is a schematic illustration of an embodiment on the assembly of the socket. Post P is inserted into the socket. It demonstrates an attachment of a wedge 410 to the socket base 405 of the socket. If the socket is driven to penetrable ground such wedge 410 may be used. Because the wedge 410 is removably connectable, different tilt or height compensation means may be arranged between the socket base 405 and the wedge 410.

[0037] FIG. 4B is a schematic illustration of an embodiment on the assembly of the socket. Post P is inserted into the socket. It demonstrates a permanent attachment of a wedge 410 onto the socket. If the ground anchor is driven to penetrable ground such wedge may be used. The wedge 410 may be welded to the socket.
