Service vehicle door system
View Patent ↗A door system for a service vehicle. The door system comprises a door frame that includes a plurality of elongated frame members, an interior panel coupled to the door frame, and a plurality of connectors for coupling the interior panel to the door frame. Additionally, each of the frame members comprises an attachment flange having a longitudinal groove and a series of longitudinally spaced insert openings. The insert openings extend entirely through the attachment flange and open into the longitudinal groove. As such, the connectors extend through the insert openings to secure the interior panel to the door frame.
1. A door system for a service vehicle, said door system comprising:
a door frame comprising a plurality of elongated frame members;
an interior panel coupled to the door frame; and
a plurality of connectors for coupling said interior panel to said door frame,
wherein each of said frame members comprises an attachment flange having a longitudinal groove and a series of longitudinally spaced insert openings, wherein said insert openings extend entirely through said attachment flange and open into said longitudinal groove,
wherein said connectors extend through said insert openings to secure said interior panel to said door frame.
2. The door system according to claim 1 , wherein each connector comprises a female threaded insert and a male threaded fastener.
3. The system according to claim 2 , wherein each insert comprises an insert head, an internally threaded sleeve, and one or more flared anchor members positioned generally between said insert head and said internally threaded sleeve, and wherein each insert is received in one of said insert openings such that said insert head and said internally threaded sleeve are positioned on generally opposite sides of said attachment flange.
4. The system according to claim 3 , wherein each fastener comprises a fastener head and an externally threaded shaft, and wherein said externally threaded shaft is threadably received in said internally threaded sleeve of said insert and said fastener head holds said interior panel against said attachment flange.
5. The system according to claim 1 , wherein said frame members are secured together in a substantially rectangular configuration.
6. The system according to claim 1 , wherein said frame members each include a main body member, an exterior panel attachment channel, and said interior panel attachment flange, wherein said interior panel attachment flange and said exterior panel attachment channel extend laterally from opposite edges of said main body member in substantially opposite directions.
7. The system according to claim 6 , wherein said door system further comprises an exterior panel attached to said exterior panel attachment channel.
8. The system according to claim 4 , wherein each of said fastener heads includes a pair of substantially parallel flattened sides that are spaced from one another by a distance that corresponds with a width of said longitudinal groove, such that the fastener heads can be received within the longitudinal grooves and can be substantially prevented from rotating.
9. The system according to claim 4 , wherein the flared anchor members of each insert are formed by deforming said insert while the insert is received in said insert opening.
10. The system according to claim 9 , wherein said flared anchor members of one of the inserts provide for the insert to have a maximum width that is at least 1.25 times a width of the insert opening in which the insert is received.
11. A vehicle with a door system for accessing a compartment within said vehicle, said vehicle comprising:
a drivers cab;
a body located behind said cab, wherein said door system is incorporated into said body;
said door system including—
a door frame comprising a plurality of elongated frame members;
an interior panel coupled to the door frame; and
a plurality of connectors for coupling said interior panel to said door frame,
wherein each of said frame members comprises an attachment flange having a longitudinal groove and a series of longitudinally spaced insert openings, wherein said insert openings extend entirely through said attachment flange and open into said longitudinal groove,
wherein said connectors extend through said insert openings to secure said interior panel to said door frame.
12. The door system according to claim 11 , wherein each connector comprises a female threaded insert and a male threaded fastener.
13. The system according to claim 12 , wherein each insert comprises an insert head, an internally threaded sleeve, and one or more flared anchor members positioned generally between said insert head and said internally threaded sleeve, and wherein each insert is received in one of said insert openings such that said insert head and said internally threaded sleeve are positioned on generally opposite sides of said attachment flange.
14. The system according to claim 13 , wherein each fastener comprises a fastener head and an externally threaded shaft, and wherein said externally threaded shaft is threadably received in said internally threaded sleeve and said fastener head holds said interior panel against said attachment flange.
15. The system according to claim 11 , wherein said frame members are formed from extruded aluminum.
16. The system according to claim 13 , wherein each insert includes one or more longitudinal slits configured to allow said inserts to deform while the insert is received in said insert opening.
17. The system according to claim 16 , wherein said inserts are configured to deform such that said flared anchor members extend radially outward from a central axis of said insert.
18. A process for forming a door system for a service vehicle, said process comprising:
(a) providing a door frame comprised of a plurality of elongated frame members, with each frame member having an attachment flange that includes a longitudinal groove and a series of longitudinally spaced apart insert openings, and with the insert openings extending entirely through the attachment flange and opening into the longitudinal groove;
(b) inserting a plurality of inserts into the insert openings, with the inserts comprising an insert head, an internally threaded sleeve, and a deformable portion;
(c) positioning an interior panel flushly against the attachment flanges of the frame members; and
(d) securing the interior panel to the door frame by inserting fasteners through the interior panel and into the inserts, with the fasteners each including a fastener head an exteriorly threaded shaft,
wherein during said securing of step (d), the inserts are deformed so as to compress the interior panel between the attachment flanges and the heads of the fasteners.
19. The process according to claim 18 , further including the step of securing an exterior panel to the door frame, wherein the exterior panel functions as an exterior portion of a body of the vehicle.
20. The process according to claim 18 , further including the step of coupling a longitudinal seal to the door frame, such that the door system is configured to seal a storage compartment of the vehicle when the door system is in a closed position.
