Description

[0001] The invention relates to a fence post profile according to claim 1 for covering a front side of a fence post having an axially extending chamber.

[0002] Fence systems with profile rails and fence slats are common for the construction of fences. The profile rails have a rectangular cross-section and are provided with longitudinal grooves on their sides into which the fence slats or panel elements are inserted. The profile rails form the fence posts. The longitudinal grooves are covered by a cap that is attached to the upper end of each profile rail. One such fence system is described, for example, in DE 20 2021 100 466 U1.

[0003] A disadvantage of these systems is that the cap attached to a profile rail can become loose due to heat, posing a risk of corrosion due to water penetration into the profile rail. Furthermore, the cap is easy to steal.

[0004] The invention aims to remedy this situation. The invention is based on the object of providing a device for covering a fence post profile with an axially extending chamber on its end face, which prevents accidental detachment. According to the invention, this object is achieved by a device having the features of patent claim 1.

[0005] The invention provides a device for covering a fence post profile having an axially extending chamber on its end face, which prevents accidental loosening. The device comprises a post cap having a shoulder on its underside for insertion into the chamber of the fence profile, which has a bore through which a screw is passed. The screw is screwed into a clamping body that can be laterally expanded by pressing against the shoulder and can be clamped against at least two boundary surfaces of the chamber, enabling a force-fit connection of the post cap to the fence profile.

[0006] In a further development of the invention, the clamping body is formed by a convexly curved sheet metal element facing the shoulder. This causes the clamping body to clamp against the boundary surfaces of the chamber in the pulling direction of the post cap.

[0007] In one embodiment of the invention, the sheet metal has at least two wings angled toward the shoulder of the post cap. This increases the clamping effect of the clamping body.

[0008] In a further embodiment of the invention, the sheet metal is provided with a threaded sleeve into which the screw is screwed. This ensures a smooth movement when tightening the screw without tilting the clamping body.

[0009] In a further development of the invention, the post cap is pyramid-shaped, with the shoulder preferably located centrally on the underside of the post cap. This creates an attractive appearance for the post cover.

[0010] In one embodiment of the invention, at least one retaining pin is arranged on the underside of the post cap, spaced apart from the shoulder. This provides additional fixation for a surface element accommodated by the fence post profile.

[0011] In a further embodiment of the invention, at least one of the arranged retaining pins has a reduced-diameter section at its end and / or is slotted. This provides improved fixation of a received surface element.

[0012] In a further development of the invention, the post cap has a recess on its upper side that aligns with the hole in the shoulder and is closed by a cover cap detachably attached to the post cap. This conceals the screw, resulting in an improved appearance of the post cap.

[0013] The present invention further relates to a fence post profile with such a device, with a chamber extending axially on the end face and at least one side provided with a longitudinal groove extending over the entire length for receiving a surface element, wherein the device is arranged on an end face of the fence post profile, the shoulder of which has a cross section which essentially corresponds to the cross section of the chamber, wherein the screw is tightened in such a way that the clamping body is clamped against at least two boundary surfaces of the chamber.

[0014] In a further development of the invention, a surface element is inserted into a longitudinal groove of the fence post profile, with at least one retaining pin arranged on the underside of the post cap at a distance from the shoulder, which pin rests against and / or surrounds the surface element. As a result, the surface element is additionally axially fixed by the post cap.

[0015] Further developments and refinements of the invention are specified in the remaining subclaims. Embodiments of the invention are illustrated in the drawings and are described in detail below. They show: Figure 1 shows a schematic spatial representation of a fence section; Figure 2 shows the fence post profile of the fence section from Figure 1 a) in a first spatial representation from above; b) a second spatial representation from below; Figure 3 shows an upper fence post profile section of the fence section from Figure 1 in longitudinal section.

[0016] The fence section chosen as an embodiment comprises a fence post profile 1, the longitudinal groove 11 of which receives surface elements in the form of panels 5 and which is covered on its upper end face with a post cap 2 which is connected to the fence post profile 1 via a clamping body 3.

[0017] In the exemplary embodiment, the fence post profile 1 is designed as an extruded aluminum hollow profile with a substantially square cross-section. On three long sides, the fence post profile 1 has a first longitudinal groove 11 in the center, which extends over its entire length and has a circular cross-section spanning an angle of 240°, whereby an undercut is formed on both sides of its longitudinal opening. The fourth side is closed. The longitudinal grooves 11 delimit a chamber 12 which has a square cross-section and extends along the center axis of the fence post profile 1. In the exemplary embodiment, panels 5 are inserted into one longitudinal groove 11, and the remaining longitudinal grooves 11 are each closed by a cover strip 6.

[0018] In the exemplary embodiment, the post cap 2 is made of aluminum and is designed in the shape of a square prism, to which a circumferential collar 21 is connected. The inner contour of the collar 21 essentially corresponds to the outer contour of the cross-section of the fence post profile 1, which the collar 21 encompasses when the post cap 2 is folded over. On its underside, the post cap 2 has a shoulder 22 for insertion into the chamber 12 of the fence profile 1. In the exemplary embodiment, the shoulder 22 is cuboid-shaped and has a rectangular cross-section. The outer surface of the shoulder 22 essentially corresponds to the inner surface of the chamber 12. The shoulder 22 has a bore 23 which merges into a stepped bore 24 running centrally through the tip of the post cap 1. A screw 4 is passed through the bore 23, the screw head 41 of which rests on a step 25 of the stepped bore 24.The screw head 41 is concealed by a prism-shaped cover 26, which is mounted centrally on the post cap 2 and forms the tip of the post cap 2. Four retaining pins 27 are arranged in the center of each side edge of the shoulder 22, spaced apart from the shoulder 22, which in the exemplary embodiment are essentially cylindrical.

[0019] The clamping body 3 comprises a substantially square clamping plate 31, on each side of which a wing 32 is angled, forming a convex shape. A non-circular, in this case hexagonal, recess 33 is formed centrally in the clamping plate 31, into which a threaded sleeve 34 is inserted. The threaded sleeve 5 has a hexagonal collar 35, with which it engages the hexagonal recess 33 of the clamping plate 1 and is firmly connected to it.

[0020] The clamping body 3 is inserted into the chamber 12, with the screw 4 screwed into the threaded sleeve 34. The wings 32, which are angled to the clamping plate 31 in the direction of the post cap 1, yield resiliently toward the recess 33 when inserted into the chamber 12.

[0021] During assembly, the post cap 2 is placed onto the fence post profile 1, with the collar 21 framing the fence post profile 1. A retaining pin 27 is pressed against the uppermost panel 7, which is thereby axially fixed. The screw 4 is now tightened, causing the clamping body 3 with its wings 32 to move against the shoulder 22 of the post cap 2. The wings 32 are pressed outwards against the boundary surfaces of the chamber 12, against which they clamp themselves. The post cap 2 is thus firmly connected to the fence post profile 1. The cover 26 is then placed centrally on the post cap 2, concealing the screw head 41 of the screw 4. For this purpose, a recess 28 with a square cross-section is made in the post cap 2, framing the stepped bore 24, into which the cover 26, which is in the shape of a prism with a square base, is inserted.
