a pair of guide plates, each of the guide plates attached below the mounting plate, each of the guide plates having a guide plate front-end and a guide plate back-end, wherein said guide plates are angled relative to each other, whereby each of the guide plate back-ends converge towards each other; and a third guide plate extending outwards from the mounting plate front-end, the third guide plate having a third guide plate upper surface, wherein the third guide plate upper surface defines an obtuse angle relative to the mounting plate upper surface, such that a hitch ball is able to be guided towards the mounting plate front-end via the third guide plate, and/or from below the mounting plate and towards the guide plate back ends via one of the guide plates attached below the mounting plate. ## Claims ### Claim 1 A trailer hitch guide adaptor for a trailer tongue coupler, comprising: a mounting plate configured for attachment to the trailer tongue coupler, the mounting plate having a mounting plate upper-surface and a mounting plate front-end; a pair of guide plates, each of the guide plates attached below the mounting plate, each of the guide plates having a guide plate front-end and a guide plate back-end, wherein the guide plates are angled relative to each other, whereby each of the guide plate back-ends converge towards each other and towards an intersection line, and wherein the guide plate back-ends are connected to each other at or around the intersection line to form a single-piece guiding-structure; and a third guide plate extending outwards from the mounting plate front-end, the third guide plate having a third guide plate upper surface, wherein the third guide plate upper surface defines an obtuse angle relative to the mounting plate upper surface, such that a hitch ball is able to be guided towards the mounting plate front-end via the third guide plate, and/or from below the mounting plate and towards the guide plate back ends via one of the guide plates attached below the mounting plate; and a reinforcement plate attached to the third guide plate upper surface, the reinforcement plate having a reinforcement plate lower surface and a reinforcement plate front-end being attached to the third guide plate upper surface, such that the reinforcement lower plate surface is parallel to the mounting plate upper surface, wherein the mounting plate and the reinforcement plate are mechanically coupled to each other, thereby reinforcing the attachment of the third guide plate to the mounting plate. ### Claim 2 (depends on 1) The trailer hitch guide adaptor according to claim 1, the mounting plate further comprising a hole adapted to receive the hitch ball such that the hitch ball is able to connect with a lock inside the trailer tongue coupler. ### Claim 3 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the mounting plate and the reinforcement plate are mechanically coupled to each other via fastening means. ### Claim 4 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the mounting plate and the reinforcement plate are mechanically coupled to each other via a connecting plate, such that the connecting plate is a plate between the reinforcement plate and the mounting plate. ### Claim 5 (depends on 4) The trailer hitch guide adaptor according to claim 4, wherein the reinforcement plate, the connecting plate and the mounting plate are made of one piece of material. ### Claim 6 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the reinforcement plate further comprises a slit with a slit-end facing the reinforcement plate front-end, whereby the slit is able to slide onto an outer surface of the trailer tongue coupler. ### Claim 7 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the mounting plate and the reinforcement plate are separated from each other, thereby forming a gap between the mounting plate and the reinforcement plate, whereby the trailer hitch guide adaptor is able to slide onto an outer surface of the trailer tongue coupler. ### Claim 8 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the pair of guide plates is angled relative to each other with an angle between 60 and 120 degrees, or around 90 degrees or around 100 degrees. ### Claim 9 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein each of the guide plate back-ends converge such that the mounting plate front-end and the guide plates defines an inscribed circle on a surface below the mounting plate with a diameter greater than 4 cm, or greater than 5 cm, or greater than 6 cm. ### Claim 10 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the obtuse angle is between 120 and 150 degrees, or around 130 degrees, or around 135 degrees, or around 140 degrees. ### Claim 11 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the third guide plate comprises a third guide plate front-end with a curved path. ### Claim 12 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein at least the mounting plate and the third guide plate are formed from a single piece. ### Claim 13 (depends on 1) A trailer tongue coupler attached with the trailer hitch guide adaptor according to claim 1. ### Claim 14 (depends on 13) The trailer tongue coupler according to claim 13, wherein the trailer hitch guide adaptor is permanently attached to the trailer tongue coupler by welding. ### Claim 15 (depends on 13) The trailer tongue coupler according to claim 13, wherein the trailer hitch guide adaptor is an integral part of the trailer tongue coupler. ### Claim 16 (depends on 1) The trailer hitch guide adaptor according to claim 1, wherein the mounting plate and the reinforcement plate are mechanically coupled to each other by means of screws, welded material and/or glue.
