2. Description of the Related Art
Japanese Unexamined Patent Publication No. 2003-232084 discloses a metallic mounting fitting for fixing an object to a fixed member. The mounting fittings are formed by press-working metallic plate materials and often must have a high strength. Strength can be enhanced by bending or embossing the metallic plate to form a reinforcement.
The fitting is bent at about 90°, and two objects are mounted fixed at the opposite ends. A reinforcing rib extends over substantially the entire length of one surface to achieve a high strength. However, the reinforcing rib can be formed over the entire length in this way only because the surfaces of the fitting that will be fixed to the objects are on only one surface of the fitting. A problem arises if both surfaces of the fitting are mounting surfaces.
The present invention was developed in view of the above problem, and an object thereof is to enhance the strength of a mounting fitting.
The invention relates to a mounting fitting formed by bending a metallic plate material and used to make an object, such as a casing for accommodating wiring for a sliding door that is to be mounted fixedly to a fixed member, such as a panel. The mounting fitting has first and second mounting panels that are displaced from one another. The first mounting panel is for opposing and mounting on the object to be mounted. The second mounting panel is for opposing and mounting on the fixed member. Reinforcing flanges are bent so that edge ends thereof face substantially in the same direction and on the same side along the longitudinal direction thereof. The reinforcing flanges are at the opposite lateral edges extending from the first mounting panel to the second mounting panel and are substantially continuous along the longitudinal direction without any cut. Thus, the strength of the mounting fitting is improved as compared to conventional ones.
The reinforcing flanges preferably are formed at the opposite lateral edges extending from the first mounting panel to the second mounting panel and at least ends of the lateral edges at one side are connected by a U-shaped curved portion. Accordingly, a long range is ensured for the continuous reinforcing flange and reinforcement is improved.
One of the mounting panels preferably is struck to bulge out in substantially the same direction as the facing direction of the edge of the reinforcing flange to form a step at a boundary between the two mounting panels. The struck surface is at a position having substantially the same height as the edge end on the struck surface or projects slightly more outward. Accordingly, there is no interference with the reinforcing flange even if both mounting surfaces are opposed to and brought into contact with the object to be mounted and the fixed member. Thus, the mounting fitting is applicable even if the object to be mounted and the fixed member are wide.
One or more substantially U-shaped grooves preferably are formed between the opposite lateral ends of a first mounting panel and the reinforcing flange upon bending the second mounting panel with respect to the first mounting panel to form a step.
An end of the reinforcing flange preferably is substantially at the same height as one mounting surface.
Longitudinal ribs preferably are on the first and/or the second mounting flange. The ribs preferably are in an intermediate position of a range extending from a step to one of the first and second mounting surfaces and sides of mounting holes in the other mounting panels.
The rib in the middle and/or the ribs at the sides preferably project in substantially opposite directions.
The rib in the middle extends over one of the steps between the second mounting panel and an inclined step and between the first mounting panel and the inclined step, respectively, while the ribs at the sides of the rib in the middle extend over the other of the steps.
The mounting fitting may further comprise at least one embossment at steps between one of the first and second mounting panels and an inclined step between the first and second mounting panels.
The mounting fitting preferably is positioned at one or more distal ends of the object to be mounted.
These and other objects, features and advantages of the present invention will become more apparent upon reading of the following detailed description of preferred embodiments and accompanying drawings. It should be understood that even though embodiments are separately described, single features thereof may be combined to additional embodiments.
Mounting fittings according to the invention are used for a power feeding device for a slide door of an automotive vehicle. Specifically, wiring for feeding power to electrical components of the door must be laid between the slide door of the automotive vehicle and a vehicle body. Thus, a casing 1 for accommodating the wiring for the door is incorporated into the door. The casing 1 has two long opposed plates made of a metal (aluminum alloy) and/or of a composite material, and wires, connectors, electric circuits and the like are accommodated in a space between the plates. Connectors are joined with ends of the wires and are electrically connectable with electrical components (e.g. a motor for moving a door glass up and down) in the door. The casing 1 is fixed to a lower part of a door inner panel 2 by mounting fittings preferably made of the same material as the casing 1.
The casing 1 receives a relatively large force, such as a pulling force, from a wire laying portion of the vehicle body when the door is opened or closed. The respective mounting fittings must have a sufficient strength against this force. In this embodiment, a conventional mounting fitting 5 is arranged in an intermediate position, and the technology of the invention is applied to mounting fittings 3, 4 arranged at the opposite ends.
The front mounting fitting 3 is at the front side with respect to a driving direction DD of the vehicle shown in
An arcuate or bent escaping recess 9 is formed substantially in the widthwise middle of the lateral edge of the first mounting panel 7 opposite the first bend line 67, and crimping holes 10 are formed at the substantially opposite sides of the escaping recess 9. Burring tubes project from the casing 1 and fit loosely into the crimping holes 10. The burring tubes then are crimped, deformed, bent or folded to fix the front mounting fitting 3.
The corners of the second mounting panel 8 opposite the second bend line 68 are arcuate, and a bolt hole 11 is formed at a position slightly displaced to one side. The bolt hole 11 is used to mount the bottom surface of the second mounting panel 8 on the inner panel 2. A reinforcing flange 12 is bent at a substantially right angle on substantially the entire periphery of the front mounting fitting 3 except the edge with the escaping recess 9. The reinforcing flange 12 is bent so that an edge 12A faces substantially away from the door inner panel 2 (up in
The rear mounting fitting 4 is arranged at the rear end of the slide door with respect to a driving direction DD of the vehicle. The rear mounting fitting 4 is mounted to bulge down at the rear end of the casing 1. The rear mounting fitting 4 has an inclined stepping panel 13 substantially in the middle. A first mounting panel 14 is defined on an upper part of the rear mounting fitting 4 in
A second mounting panel 16 is defined at the lower part of the front mounting fitting 4 bulging out from the casing 1 and is joined unitarily to the stepping panel 13 along a second bend line 1613 that is substantially parallel to the first bend line 1413. Thus, the first and second mounting panels 14 and 16 are substantially parallel but offset. The surface of the second mounting panel 16 facing down in
The rear mounting fitting 4 is required to be stronger than the other two mounting fittings 3, 5. Thus, ribs 20 are provided in addition to the reinforcing flange 18. More particularly, substantially parallel ribs 20A and 20B extend from the first panel 14 to the stepping panel 13 and are disposed symmetrically on opposite respective sides of the crimping holes 15. Additionally, the ribs 20A and 20C extend continuously across the first bend line 1413 substantially perpendicular to the first bend line 1413. The ribs 20A and 20B project down in
The middle mounting fitting 5 is arranged in the intermediate position shown in
An inclined stepping panel 21 is formed at an intermediate position of the middle mounting fitting 5, and a first mounting panel 22 is formed at a lower part thereof in
Reinforcing flanges 25A, 25B are bent in substantially opposite directions at the first and second mounting panels 22, 24. In other words, the reinforcing flange 25A of the first mounting panel 22 is bent substantially at a right angle in a direction opposite to the casing 1, whereas the reinforcing flange 25B of the second mounting flange 24 is bent substantially at a right angle in a direction substantially opposite to the inner panel 2. Accordingly, the two reinforcing flanges 25A, 25B make cuts 26 at the stepping panel 21. Reinforcing ribs 27 are formed by embossing.
The reinforcing flanges 12, 18 formed on the front and rear mounting fittings 3, 4 are substantially continuous without any cut along their longitudinal directions. Thus, the entire mounting fittings 3, 4 have high strengths and can sufficiently resist even the repeated exertion of forces resulting from the opening and closing of the slide door. Further, the reinforcing flanges 12, 18 are formed along the opposite lateral edges in the longitudinal direction, and also at the U-shaped edges that couple these lateral edges. Thus, the strength can be enhanced further. An area defined by the reinforcing flange could be struck to bulge up to substantially the same height as the edge of the reinforcing flange or to bulge further out as an area of the first mounting panel 14 of the rear mounting fitting 4 defined by the reinforcing flange 18 is struck to bulge up to the substantially same height as the edge 18A of the reinforcing flange 18, and no consideration needs to be made on the interference with the reinforcing flange upon mounting the mounting fitting on the casing 1. Thus, the mounting fitting can be mounted utilizing a wide flat surface of the casing 1.
The invention is not limited to the above described and illustrated embodiment. For example, the following embodiments are also embraced by the technical scope of the present invention as defined by the claims. Beside the following embodiments, various changes can be made without departing from the scope and spirit of the present invention as defined by the claims.
Mounting fittings for the casing 1 of the slide door are shown in the foregoing embodiment. However, an object to be mounted or a fixed mating partner is not limited.
The mounting fittings need not be always fixed to the casing 1 or the inner panel 2 by crimping, and may be fixed by bolting, welding, riveting or other means or a plurality of these means may be used in combination.
The reinforcing flange is long and includes the U-shaped curved portion in the foregoing embodiment. However, it may not have the curved portion provided that it continuously extends without any cut along longitudinal direction at least over the first and second mounting surfaces.
