Trailer coupler assembly
View Patent ↗A trailer coupler pivot assembly comprising a pivot mount member connected to a trailer frame member and a hinge bracket connected to a trailer tongue arm. The hinge bracket is pivotally connected to the pivot mount member so that the trailer tongue arm is pivotal relative to the trailer frame member between an open position and a closed position. However, either of the pivot mount member or the hinge bracket comprises a single, prefabricated component to make assembly more efficient and cost effective. With both the pivot mount member and the hinge bracket being single, prefabricate components, the trailer coupler pivot assembly can be more easily installed with fewer components and welds and by less skilled labor.
1. A trailer coupler pivot assembly comprising:
a trailer frame mount member comprising a single prefabricated component, the trailer frame mount member including:
a first body;
a first bore passing through the first body;
a second bore passing through the first body; and
a first flange member extending from the first body for securing the trailer frame mount member to a trailer frame;
a trailer tongue mount member comprising a single prefabricated component, the trailer tongue mount member including:
a second body;
a third bore passing through the second body;
a fourth bore passing through the second body; and
a second flange member extending from the second body for securing the trailer tongue mount member to a trailer tongue; and
a connector passing through the first bore and the third bore to pivotally connect the trailer frame mount member and the trailer tongue mount member.
2. The trailer coupler pivot assembly of claim 1 , where the first flange member includes a mounting aperture for alignment with a corresponding aperture in the trailer frame to secure the trailer frame mount member to the trailer frame via bolts.
3. The trailer coupler pivot assembly of claim 2 , where the bolts include shanks that are larger in diameter than diameters of the apertures.
4. The trailer coupler pivot assembly of claim 3 , where the trailer frame mount member includes a third flange member extending from the first body.
5. The trailer coupler pivot assembly of claim 1 , where the second flange member includes a mounting aperture for alignment with a corresponding aperture in the trailer tongue secure the trailer tongue mount member to the trailer tongue via bolts.
6. The trailer coupler pivot assembly of claim 5 , where the bolts include shanks that are larger in diameter than diameters of the apertures.
7. The trailer coupler pivot assembly of claim 6 , where the trailer tongue mount member includes a fourth flange member extending from the second body.
8. The trailer coupler pivot assembly of claim 1 , where the trailer frame mount member is manufactured form cast metal.
9. The trailer coupler pivot assembly of claim 1 , where the trailer tongue mount member is manufactured from cast metal.
10. The trailer coupler pivot assembly of claim 1 , where the trailer frame mount member is manufactured from powdered metal.
11. The trailer coupler pivot assembly of claim 1 , where the trailer tongue mount member is manufactured from powdered metal.
12. The trailer coupler pivot assembly of claim 1 , where the trailer frame mount member is pivotally connected to the trailer tongue mount member along a substantially vertical axis so that the trailer tongue pivots relative to the trailer frame between an open position and a closed position through a substantially horizontal plane.
13. A trailer coupler pivot assembly comprising:
a trailer frame;
a coupler tongue;
a single prefabricated trailer mount member including a first extending flange for mounting the trailer frame mount member to the trailer frame;
a single prefabricated coupler tongue mount member including a second extending flange for mounting the coupler tongue mount member to the coupler tongue; and
a connector for pivotally connecting the trailer frame mount member and the trailer tongue mount member so that the trailer tongue is pivotal relative to the trailer frame between an open position and a closed position.
14. The trailer coupler pivot assembly of claim 13 , where the coupler tongue mount member further comprises a pair of integral support members having a pivot mount receiving portion.
15. The trailer coupler pivot assembly of claim 14 , where the coupler tongue mount member includes a third extending flange confronting the second extending flange.
16. The trailer coupler pivot assembly of claim 15 , where the support members are vertically oriented relative to each other and where each of the support member includes a pair of opposed bores, where the bores of each support members are vertically aligned with the corresponding bores of the other support members so as to define a pivot axis and a lock axis.
17. The trailer coupler pivot assembly of claim 16 , where the trailer frame mount member further comprises a pair of integral sleeve portions configured to be pivotally received with the pivot mount receiving portion of the trailer tongue mounting member when the pivot assembly is in the closed position.
18. The trailer coupler assembly of claim 17 , where the sleeve portions are horizontally oriented relative to each other and where each of the sleeve portions include a vertical bore, where one vertical bore is vertically aligned between corresponding bores in the support members to further define the pivot axis.
19. The trailer coupler pivot assembly of claim 18 , where the other vertical bore of the other sleeve section is vertically aligned between the other corresponding bores in the support members when the coupler tongue is pivoted to the closed position to define a pin-receiving bore alignment for preventing pivot movement of the coupler tongue.
20. The trailer coupler pivot assembly of claim 19 , where a removable pin is capable of insertion through the pin-receiving bore alignment when the coupler tongue is rotated to the closed position.
