Fitting holes 7 and 7' are formed at corresponding positions of the L-shaped fixture D' and the water-proof packing E'.
In the above arrangement, the water-proof packing E' is forced to contact the internal surface of the L-shaped fixture D' and the engaging recesses 15b, 15b provided on the end faces of the raised parts 15a, 15a are engaged with the tapered engaging members 13, 13 in the cutaway parts 3b, 3b, thereby these members being coupled without using a bond. In this case, a transversal protrusion 16 provided on the rear surface of the guideway 3 of the main plate part 1 engages with a transversal through hole 17 formed near the raised part 15a of the main plate part 14 whereby the water-proof packing E' is prevented from coming out when the door is closed and the weather strip J is compressed accordingly. (see FIG. 8).
In the above arrangement of the assembly, a continuous smooth surface is formed across the weather strip guideway 3 of the L-shaped fixture D' to the weather strip abutment part 15 of the water-proof packing E' when a pressure is applied to the weather strip J.
In the case of the water-proof packing E" shown in FIG. 9, an arc-shaped weather strip abutment member 18 which connects opposing members 14a, 14a is integrally formed at a part of the main body part 14 corresponding to the weather strip guideway 3 and the water-proof packing E" is combined with the L-shaped fixture D' while the weather strip abutment member 18 is positioned in the weather strip guideway 3 of the L-shaped fixture D' while the weather strip abutment member is being stretched (FIG. 10).
With this construction, adhesion of the weather strip J to the water-proof packing E" is improved and complete water proofing can be ensured.
In FIGS. 11 to 14, the L-shaped recess (see FIG. 1) is not provided on the side plate part A1' and the inner plate part A2' of the door frame A'. Therefore the fixture D" is non-L-shaped and comprises a flat fitting plate part 1".
The fitting plate part 1" is provided with a connector through hole 2" and the weather strip guideway 3 is provided on the surface of the fitting plate part. Tapered abutment parts 3a, 3a are formed at both sides of the weather strip guideway 3 and cutaway parts 3b, 3b are provided outside the tapered abutment parts 3a, 3a.
A fitting lug 1a" provided with a fitting hole 7 is provided on an outer periphery of the fitting plate part 1" and a temporary engaging projection 18 having a bulged engaging part 18a at its extreme end part is provided at the outer side of the inner surface whereby an accommodating groove 19 for accommodating the door wire harness C which reaches from the connector through hole 2" to the other open end 19a is formed between a pair of temporary engaging projections 18, 18.
The approximately U-shaped water-proof packing E is adhered to the outer periphery of the fitting plate part 1" except for the open end 19a of the accommodating groove 19 and part of the water-proof packing E is positioned facing the cutaway parts 3b, 3b which are formed at both side ends of the weather strip guideway 3.
A sealing material E1 is continuously applied to the outer periphery inside the accommodating groove 19 except for the open end 19a and a sealing material E2 is applied annularly to the periphery of the temporary engaging projection 18 on the internal surface of the fitting plate part 1".
In the above-described construction, the strap part 10 of the door wire harness C extended in the door frame A' is arranged from the open end 19a to the accommodating groove 19 and the main connector G' at the end part is fixed in the through hole 2". Then, the accommodating groove 19 is closed with the under cover F', which is fixed with screws 11 through fitting holes 8, 8'. At this time, a rib 20 which is protruded at the peripheral edge of the under cover F' contacts under pressure with the sealing material E1 to prevent water from entering into the accommodating groove 19 (see FIG. 13).
The fixture D" which has been assembled as described above is arranged in contact with the side plate part A1' of the door frame A', the temporary engaging projection 18 is positioned in a slit 21b of an engaging hole 21 by inserting the temporary engaging projection 18 into an expanded hole portion 21a of the engaging hole 21 (see FIG. 12) and sliding the fitting fixture D" in the outward direction of the door frame A', and the bulged engaging part 18a is engaged with the rear surface of the slit 21b and temporarily fixed. Then the fixture D" is finally fixed with screws 11 to the door frame A' through fitting holes 7, 7" which have been temporarily aligned. In this case, the water-proof packing E contacts under pressure with the door frame A' and primarily prevents ingress of external water into the inside of the fixture D".
Subsequently, the weather strip J is arranged on the fixture D" while being positioned in the weather strip guideway 3 and fixed, as shown in FIG. 3, by fitting the clamp to the fitting hole of the door frame A'. When the door is closed, the weather strip g receives a pressure to depress the water-proof packing E which is bulged from the tapered abutment part 3a of the weather strip guideway 3 whereby the water-proof packing E is disposed to eliminate the clearance in the range from the tapered abutment part 3a to the surface of the door frame A' (see FIG. 13).
As shown in FIG. 15, in two independent hollow chambers 22 and 23 of the weather strip J, a rod type cushion member 24 containing a sponge buffer is accommodated in the outer hollow chamber 23 to prevent a fall of the contact pressure load due to deterioration of the weather strip J.
In a first aspect of the invention, the water-proof packing is filled in a clearance between the L-shaped fixture and the L-shaped recess and between the weather strip and the L-shaped fixture to the door frame to shut off ingress of water into the vehicle cabin. The side plate part and the L-shaped fixture are structured to closely contact each other and therefore water proofing by the L-shaped fixture can be easily attained without depending on the press-molded shape of the L-shaped recess on the side plate part of the door frame.
In a second aspect of the invention, the above-described object can be attained without adhering in advance the water-proof packing to the L-shaped fixture.
In a third aspect of the invention, the water-proof effect of the water-proof packing can be further improved.
In a fourth aspect of the invention, the door wire harness can be drawn out by the fixture without forming the L-shaped recess and the water-proof effect between the weather strip and the fixture to the door frame can be ensured.
In a fifth aspect of the invention, a fall of the contact pressure load due to deterioration of the weather strip can be prevented.
