Detailed Description of the Preferred Embodiments
The present invention will be described in detail with reference to the accompanying drawings which illustrate preferred different embodiments according to the present invention.
Referring to FIG. 1, a vehicle includes a windshield 28, a front pillar 30, a front roof section 32, a detachable roof section 38, a rear roof section 36, a center pillar 35 and a rear window 34. The front pillar 30 is connected and secured to the front roof section 32. The front pillar 30 and the front roof section 32 surround the windshield 28 (i.e., the front pillar 30 and the front roof section 32 constitute a windshield frame). The rear roof section 36 is connected to the center pillar 35. The rear roof section 36 and the center pillar 35 constitute a roll bar.
The detachable roof section 38 is positioned between the front roof section 32 and the rear roof section 36, and the detachable roof section 38 covers a passenger compartment. The detachable roof section 38 includes front and rear portions.
As shown in FIGS. 2 and 3, the front portion of the detachable roof section 38 is selectively mounted on the front roof section 32, and the detachable roof section 38 is selectively secured to the front roof section 32. The front portion of the detachable roof section 38 includes a plurality of holes 18 and a plurality of projections 22. Each hole 18 is located apart from the corresponding projection 22 in the lateral direction of the vehicle. A nut 14 or first engaging member is secured to the front portion of the detachable roof section 38. A center line of the nut 14 corresponds to a center line of the hole 18 of the detachable roof section 38.
The front roof section 32 includes a plurality of brackets 44 which project rearwardly in the longitudinal direction of the vehicle. Each bracket 44 includes two spaced holes 20 and 26 therewithin. One hole 20 of each bracket 44 corresponds to or is aligned with the hole 18 of the detachable roof section 38. In a normal condition, the other hole 26 of the bracket 44 corresponds to the projection 22 of the detachable roof section 38. A guiding member 24 is inserted into the hole 26 for the projection 22. The guiding member 24 includes a guiding surface 241 and a positioning hole 242.
The holes 18 in the detachable roof, the nuts 14 and the projections 22 of the detachable roof section 38, the aligning holes 20 of the bracket 44 and the guiding members 24 of the front roof section 32 and the bolts 12 constitute a first fastening means.
In a normal securing condition, as shown in FIGS. 2 and 3, a bolt 12 or second engaging member is inserted into the aligned holes 20 and 18, and the bolt 12 engages with the nut 14. Simultaneously, the projection 22 is positioned within the positioning hole 242. Accordingly, the detachable roof section 38 and the front roof section 32 form a substantially flush surface, and a space defined between the detachable roof section 38 and the front roof section 32, is effectively sealed by a weather strip 76.
However, when due to manufacturing error, the projection 22 of the detachable roof section 38 is not aligned with the positioning hole 242 of the guiding member 24, the projection 22 of the detachable roof section 38 is located on the guiding surface 241 of the guiding member 24. Accordingly, the detachable roof section 38 projects from the front roof section 32, and sealing effect between the detachable roof section 38 and the front roof section 32 is deteriorated.
Thus, in order to prevent the detachable roof section 38 from projecting from the front roof section 32, a first distance, defined between the projection 22 and the hole 18 of the detachable roof section 38, must be the same as a second distance defined between the aligned hole 20 of the front roof section 32 and the positioning hole 242 of the guiding member 24.
However, when due to manufacturing error, the first distance is not the same as the second distance, the detachable roof section 38 might not be secured to the front roof section 32 or the sealing effect between the detachable roof section 38 and the front roof section 32 might be deteriorated.
FIGS. 5 and 6 show a second fastening means embodiment, provided between the detachable roof section 38 and the front roof section 32.
As shown in FIG. 6, the second fastening means includes guiding means 50 and a bolt 68. The guiding means 50 is inserted into a hole 46 defined within a pillar inner panel 42 and an aligned hole 48 defined within a bracket 44. The guiding means 50 includes a flange 52 secured to the bracket 44 by welding. The guiding means 50 includes a tapered hole 54 (i.e., the inner diameter of the lower edge of tapered hole 54 is larger than the inner diameter of the upper edge of tapered hole 54) and the tapered hole 54 includes a smooth surface thereon. A front portion of the bracket 44 is sandwiched between and secured to the pillar inner panel 42 and a roof header outer panel 40. The pillar inner panel 42 is connected to the front pillar 30. The roof header outer panel 40 constitutes a rear portion of the front roof section 32. A weather strip 82 is mounted on a rear portion of the roof header outer panel 40. The bracket 44 extends rearwardly in the longitudinal direction of the vehicle. The bracket 44 is located vertically below an outer surface of the front roof section 32.
The detachable roof section 38 includes a roof outer panel 56 and a roof inner panel 58.
A front edge of the roof outer panel 56 is secured to a front edge of the roof inner panel 58. The weather strip 82 is sandwiched between the roof header outer panel 40 and the front edge of the roof outer panel 56, as a result, a space, defined between the roof header outer panel 40 and the front edge of the roof outer panel 56, is effectively sealed.
A portion of the roof inner panel 58 projects downwardly and includes a hole 62. A reinforcement 60 is secured to the projecting portion of the roof inner panel 58, and includes another hole 64 corresponding to and aligned with the hole 62 of the roof inner panel 58. A nut 66 is welded on the reinforcement 60, and the nut 66 includes a threaded hole. The nut 66 has the function of a first engaging member. The center line of the threaded hole of the nut 66 is the substantially aligned with the center line of the hole 62 of the roof inner panel 58.
The bolt 68 of the second fastening means includes a threaded engaging portion 681 and a head portion 682. The head portion 68 includes a smooth tapered surface 72, a flange 70 and an adjusting recess 74. The bolt 68 functions as a second engaging member. The tapered surface 72 includes a small diameter edge and a large diameter edge. The outer diameter of the small diameter edge of the tapered surface 72 of the bolt 68 is smaller than the outer diameter of the upper edge of the tapered hole 54 of the guiding means 50. The outer diameter of the large diameter edge of the tapered surface 72 of the bolt 68 is greater than the inner diameter of the upper edge of the tapered hole 54 of the guiding means 50. The outer diameter of the large diameter edge of the tapered surface 72 of the bolt 68 is smaller than the inner diameter of the lower edge of the tapered hole 54 of the guiding means 50. The small diameter edge of the tapered surface 72 is located in the vicinity of the threaded portion 681 of the bolt 68. The large diameter edge of the tapered surface 72 is located apart from the threaded portion 681. The flange 70 extends outwardly and is located in the vicinity of the large diameter portion.
When the threaded portion 681 of the second bolt 68 engages with and is threaded into the threaded hole of the nut 66, the guiding means 50 is clamped between the flange 70 of the bolt 68 and the projection portion of the roof inner panel 58. In this condition, a portion of the tapered surface 72 of the bolt 68 is not in contact with a portion of the tapered hole 54 of the guiding means 50. An adjusting recess 74 is defined within the head portion 682, and when the bolt 68 is to be threaded into or out of the nut 66, a coin or a screwdriver is inserted into the adjusting recess 74.
The process of fastening the detachable roof section 38 to the front roof section 32 is disclosed hereinafter.
First, the detachable roof section 38 is mounted on the front and rear roof sections 32 and 36 of the vehicle.
When the detachable roof section 38 is not positioned properly, the center line of the guiding means 50 is located apart from the center line of the bolt 68.
However, when the bolt 68 is threaded into the nut 66, the tapered surface 72 of the bolt 68 contacts the tapered hole 54 of the guiding means 50.
As a result, the bolt 68 forces the detachable roof section 38 to move toward the proper position.
Therefore, the detachable roof section 38 is positioned properly and the space defined between the front edge of the detachable roof section 38 and the front roof section 32, is securely sealed.
However, the bolt 68 is separatable from the front roof section 32 so that when the detachable roof section 38 is removed from the front roof section 32 and the rear roof section 36, it is troublesome to retain the bolt 68 in a suitable position.
FIGS. 7 through 9 show a third fastening means, provided between the detachable roof section 38 and the front roof section 32, according to the present invention.
As shown in FIG. 8, the third fastening means includes the guiding means 50, a bolt 68, an under cover 76 and holding means 80. The guiding means 50 is inserted into a hole 46 defined within a pillar inner panel 42 and an aligned hole 48 defined within a bracket 44. The guiding means 50 includes a flange 52 secured to the bracket 44 by welding. The guiding means 50 includes a smooth tapered hole 54 (i.e., the inner diameter of the lower edge of the tapered hole 54 is larger than the inner diameter of the upper edge of the tapered hole 54). A front portion of the bracket 44 is sandwiched between and secured to the pillar inner panel 42 and a roof header outer panel 40. The pillar inner panel 42 is connected to the front pillar 30. The roof header outer panel 40 constitutes a rear portion of the front roof section 32. A weather strip 82 is mounted on a rear portion of the roof header outer panel 40. The bracket 44 extends rearwardly in the longitudinal direction of the vehicle. The bracket 44 is located vertically below an outer surface of the front roof section 32.
The detachable roof section 38 includes a roof outer panel 56 and a roof inner panel 58.
A front edge of the roof outer panel 56 is secured to a front edge of the roof inner panel 58. The weather strip 82 is sandwiched between the roof header outer panel 40 and the front edge of the roof outer panel 56, as a result, a space defined between the roof header outer panel 40 and the front edge of the roof outer panel 56, is effectively sealed.
A portion of the roof inner panel 58 projects downwardly and includes a hole 62. A reinforcement 60 is secured to the projecting portion of the roof inner panel 58, and includes an aligned hole 64 corresponding to the hole 62 of the roof inner panel 58. A nut 66 is welded on the reinforcement 60, and the nut 66 includes a threaded hole. The nut 66 functions as a first engaging member. The center line of the threaded hole of the nut 66 is substantially aligned with the center line of the hole 62 of the roof inner panel 58.
The bolt 68 of the second fastening means includes a threaded portion 681 and a head portion 682. Further, the head portion 682 includes a tapered surface 72, a flange 70 and an adjusting recess 74. The bolt 68 functions as a second engaging member. The tapered surface 72 includes a small diameter edge and a large diameter edge. The tapered surface 72 is a smooth surface. The outer diameter of the small diameter edge of the tapered surface 72 of the bolt 68 is smaller than the outer diameter of the upper edge of the tapered hole 54 of the guiding means 50. The outer diameter of the large diameter edge of the tapered surface 72 of the bolt 68 is greater than the inner diameter of the upper edge of the tapered hole 54 of the guiding means 50. The outer diameter of the large diameter edge of the tapered surface 72 of the bolt 68 is smaller than the inner diameter of the lower edge of the tapered hole 54 of the guiding means 50. The outer diameter of the small diameter edge of the tapered surface 72 is located in the vicinity of the threaded portion 681 of the bolt 68. The outer diameter of the large diameter edge of the tapered surface 72 is located apart from the threaded portion 681. A flange 70 is located in the vicinity of the large diameter portion and the flange 70 extends outwardly.
The under cover 76 is secured to a lower surface of the pillar inner panel 42. The under cover 76 includes a bottom flange 761 and an aperture 78 defined within the bottom flange 761. A center line of the aperture 78 corresponds to the center line of the tapered hole 54 of the guiding means 50. The aperture 78 has a smaller diameter than the inner diameter of the upper edge of the tapered hole 54 of the guiding means 50.
Accordingly, even when the bolt 68 is not engaged with the nut 66, the bolt 68 can not drop out from the under cover 76.
Further, the holding means 80 is preferably a conical spring. One end of the conical spring 80 is fixed to the lower surface of the pillar inner panel 42 and the other end of the conical spring 80 is inserted into and secured to a V-shape securing groove 683 defined within the flange 70 of the bolt 68. As shown in FIG. 9, the conical spring 80 biases the bolt 68 toward the bottom flanges 761 of the under cover 76. Furthermore, the entire flange 70 of the bolt 68 is biased uniformly downwardly by the conical spring 80.
Accordingly, even when the bolt 68 is not engaged with the nut 66, the bolt 68 does not move in the under cover 76. As a result, the bolt 68 does not make any noise in the under cover 76.
Further, the conical spring 80 maintains the position of the bolt 68 within the under cover 76. Thus, the bolt 68 remains aligned with the nut 66, so that it is very easy for an operator to initiate engagement of the bolt 68 with the nut 66 of the detachable roof section 38.
Moreover, the bolt 68 is covered by the under cover 76, so that the appearance is improved.
Furthermore, when the threaded portion 681 of the bolt 68 engages with and is threaded into the threaded hole of the nut 66 against the biasing force of the conical spring 80, the guiding means 50 is clamped between the flange 70 of the second bolt 68 and the projecting portion of the roof inner panel 58. In this condition, a portion of the tapered surface 72 of the bolt 68 is not in contact with a portion of the tapered hole 54 of the guiding means 50. The adjusting recess 74 is defined within the head portion 68, and when the bolt 68 is screwed, a coin or a screw driver is inserted into the adjusting recess 74.
The process of fastening the detachable roof section 38 to the front roof section 32 is disclosed hereinafter.
First, the detachable roof section 38 is mounted on the front and rear roof sections 32 and 36 of the vehicle. If the detachable roof section 38 is not properly located, the center line of the guiding means 50 is not aligned with the center line of the bolt 68. However, when the bolt 68 is threaded into the nut 66 against the biasing force of the conical spring 80, the tapered surface 72 of the bolt 68 contacts with the tapered hole 54 of the guiding means 50. As a result, the bolt 68 forces the detachable roof section 38 to move toward the proper position. Therefore, the detachable roof section 38 is properly positioned and a space, defined between the front edge of the detachable roof section 38 and the front roof section 32, is securely sealed.
FIGS. 10 and 11 show a second embodiment of the third fastening means according to the present invention. The second embodiment is substantially similar to the first embodiment shown in FIGS. 7 through 9.
However, the second embodiment uses a plate spring 84 as the holding means, instead of the conical spring 80 of the first embodiment.
As shown in FIG. 11, the plate spring 84 includes an aperture 86, an engagement recess 90 and a corrugated portion 92.
As shown in FIG. 10, the plate spring 84 is secured to the pillar inner panel 42 by a screw 88. The second bolt 68 is inserted into and engaged with an engagement recess 90 of the plate spring 84. The corrugated portion 92 of the plate spring 84 allows the bolt 68 to move in the vertical and longitudinal direction of the vehicle.
