This application relates to the following commonly owned patent applications: “FREIGHT RAILROAD CAR REFLECTOR,” Ser. No. 29/246,213, now Pat. No. Des. 541,700; and “FREIGHT RAILROAD CAR REFLECTOR,” Ser. No. 29/246,211, now Pat. No. Des. 541,193.
Thousands of people are hurt or killed at railroad crossings each year. Railroad crossings in urban and suburban areas usually have conventional warning systems such as lighting systems and/or gates which block entry to the railroad tracks when trains approach and pass through the crossings. However, many railroad crossings in rural areas do not have any warning systems. These crossings usually have signs to alert drivers of vehicles that they are about to cross over railroad tracks. During daylight hours, these signs and the tracks are usually readily visible. During night time hours, these signs and the tracks are much less visible, and sometimes based on conditions hardly visible at all.
Conventional freight railroad cars are not illuminated and are not equipped or constructed with reflective materials. During night time hours, many accidents occur simply because the drivers of vehicles cannot see the dark freight railroad cars and do not know that freight railroad cars are running through the crossing. These vehicles simply run into the moving railroad cars. This problem for vehicles (as well as for snowmobiles and ATV's) is so common that on Jan. 3, 2005, the United Sates Federal Railroad Administration issued final regulations mandating that reflective material be placed on all freight railroad cars within ten years or by 2015 at least according to a minimum schedule set forth in the regulations. The regulations are 49 CFR Part 224 entitled “Reflectorization of Rail Freight Rolling Stock; Final Rule.” These regulations further describe the extent of the existing problems. These regulations require railroads to place reflective material of minimum designated sizes on the freight railroad cars at minimum spaced apart designated positions.
This is an extraordinarily large and expensive undertaking for the railroads because there are over 1.6 million freight railroad cars and locomotives in North America. For purposes of this application, the term freight railroad cars includes locomotives. Each railroad car will have approximately 14 to 22 pieces of reflective material mounted on that railroad car. Thus, between 22 million and 35 million pieces of reflective material will need to be mounted on the freight railroad cars. Equipping the large number of freight railroad cars in accordance with these regulations has been and continues to be an extremely slow process, in part because the railroads are equipping their freight cars by directly placing adhesive backed reflective tape on portions of the freight railroad cars such as the frames and side walls of the freight railroad cars. There are several problems with attaching such reflective tape directly to the freight railroad cars. One problem is that the freight railroad cars must be taken out of service for a relatively significant amount of time during the attachment process. Another problem is that the freight railroad cars are usually extremely dirty and must be cleaned before the adhesive backed reflective tape is directly placed on the freight railroad cars for proper adherence. Another problem is the freight railroad cars tend to be rusty and the adhesive backed tape does not adhere to rust very well. This cleaning may include washing, sanding, blasting, grinding, painting and drying processes. The cleaning can take several hours for each freight railroad car. This cleaning is thus extremely time consuming, inefficient and expensive. This overall process of directly attaching adhesive backed reflective tape to each freight railroad car can take between 2 to 5 hours. This is a substantial man-hour cost. These problems dramatically slow the entire process of equipping the 1.6 million freight railroad cars according to the regulations.
To avoid these problems and significant costs, some railroads may be directly applying reflective tape to the dirty freight railroad cars to save time and cost. The problem with this is that the adhesive backed reflective tape is much more likely to not stick to, peel off or otherwise come off such dirty or rusty surfaces, and thus result in a freight railroad car without the necessary reflective material according to the regulations. After the reflective material comes off, it is less likely to be put back on in a short time period.
A further problem is that the adhesive backed reflective tape is preferably applied when the temperature is above 50 degrees Fahrenheit. If the temperature is significantly below 40 degrees Fahrenheit, and particularly if the surface of the freight railroad car is below 40 degrees Fahrenheit, then the adhesive backed reflective tape may not readily stick to the surface of the freight railroad car. Similarly, a further problem is that it is difficult to apply the reflective tape in bad weather such as rain or snow. This also dramatically increases the time and cost of equipping freight railroad cars according to the regulations.
Another problem with directly applying reflective tape to the freight railroad cars is that many surfaces of the freight railroad cars are not flat because they have been dented or otherwise damaged. This can further slow down the installation process and can cause the reflective tape to peel or otherwise come off more readily. A further problem is that the adhesive backed reflective tape directly applied to the railroad is not protected and is subject to external forces which can cause damage to the reflective tape.
Accordingly, there is a need for a much easier, much faster and less expensive method and apparatus for equipping freight railroad cars with reflective material according to the regulations.
Additionally, there is a need for a method and apparatus that will encourage railroads to equip their freight railroad cars ahead of the schedule required by the regulations.
The present invention provides a much faster, much more cost efficient and much easier apparatus and method for equipping freight railroad cars in accordance with the regulations set forth in 49 CFR Part 224. In one embodiment, the present invention provides a plurality of freight railroad car reflectors or reflector apparatus which are each attached to a freight railroad car at spaced apart locations along the exterior side walls of the freight railroad car. The freight railroad car reflectors are each suitably sized and can each be attached horizontally, vertically or otherwise in accordance with the regulations. Each freight railroad car reflector or reflector apparatus can be easily and quickly attached to the freight railroad car without the need to clean the freight railroad car and without the need for the temperature being at minimum levels or the weather being otherwise good. Moreover, the freight railroad cars may not need to be taken out of service or only taken out of service for a relatively short period of time.
One embodiment of the railroad car reflector apparatus of the present invention includes a mounting member, a reflector or reflector material attached to the mounting member and one or more fasteners or attachment mechanisms used to easily and quickly attach the railroad car reflectors to the freight railroad car. In one embodiment, the fasteners or attachment mechanisms are inserted though mounting apertures in the mounting member of the railroad car reflector and into existing holes in the freight railroad cars such as in the side wall screens of autorack railroad cars. In other embodiments, the fastener or attachment mechanism is maintained by the mounting member. In one such embodiment, the fasteners or attachment mechanisms include weld washers integrally formed with the mounting members of the railroad car reflector to facilitate quick welding of the railroad car reflector to the freight railroad car. In further embodiments, the fasteners or attachment mechanisms such as weld washers are configured to be easily attached to and removably held by the mounting members to facilitate quick welding of the railroad car reflector to the freight railroad car. These embodiments provide apparatus and methods for easy assembly of the attachment mechanisms and the mounting members and thus simplify the manufacturing process and installation procedures of the railroad car reflector. Other suitable attachment mechanisms can be employed in accordance with the present invention. The present invention thus contemplates a method of attaching reflective material to freight railroad cars in an easy, cost efficient, and effective manner.
The present invention thus contemplates a freight railroad car and particularly an improved freight railroad car equipped with a plurality of spaced apart reflector apparatus. The present invention further contemplates that because the reflector apparatus of the present invention can be easily and readily installed in shorter time periods than the previous direct attachment of the adhesive backed reflective tape, that more railroad cars can be more quickly installed with these reflector apparatus and that less accidents can occur and that less people will be hurt or killed.
Additional features and advantages of the present invention are described in, and will be apparent from, the following Detailed Description of the Invention and the figures.
Referring now to the figures,
Another known type of freight railroad car is an autorack railroad car 20 generally illustrated in
The sidewalls of an autorack railroad car includes a series of steel vertical posts 38 which are mounted on and extend upwardly from the frame 22. The roof 32 is mounted on and supported by these vertical posts. The vertical posts are spaced along the entire length of both sidewalls of the autorack car. A plurality of rectangular galvanized steel sidewall panels 40 which extend horizontally and are vertically spaced apart are mounted between each pair of vertical posts 38. These sidewall panels are supported at their corners by brackets (not shown) that are suitably secured to the vertical posts. The average sidewall panel has a multiplicity of round sidewall panel holes 42. These sidewall panel holes 42 provide the autorack car with natural light as well as proper ventilation. Proper ventilation prevents harm from the toxic vehicle fumes to the person or persons loading or unloading the vehicles into or out of the autorack car.
The autorack car may be a tri-level car having first, second and third levels. Normally, eighteen passenger vehicles can be transported in a tri-level autorack car, six on each level. The autorack car can also have two levels for vehicles instead of three. The bi-level autorack car has a lower level and an upper level. The bi-level autorack car is generally used to transport larger vehicles, such as vans, mini-vans, pickup trucks, four-by-four and cross-over vehicles. The bi-level autorack car can usually transport twelve of these vehicles, six on each level. The autorack car may also be a single-level car.
In one embodiment, the reflector apparatus 50 also includes suitable fasteners or attachment mechanisms for attaching the mounting member or base 52 to the freight railroad car such as the fasteners or attachment mechanisms 62a, 62b, 62c and 62d as generally illustrated in
As best illustrated in
The reflector apparatus 50 may be made from any suitable material(s). The mounting member or base 52 may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 54 of the reflector apparatus 50 is in one embodiment a suitable adhesive backed reflective tape such as a reflective tape commercially available from 3M, Avery Dennison and Reflexite. These entities sell reflective tape approved by the Federal Railroad Association and labeled FRA-224. Certain requirements for such reflective tape are set forth in the above mentioned regulations. The present invention contemplates that the adhesive backed reflective tape can be placed on the reflector supporter in a controlled environment (such as in a factory or inside a suitable room where the temperature and other conditions are controlled and the reflector support is clean and flat) such that maximum adhesive properties are achieved. This provides a great advantage over directly placing the reflective tape on the freight railroad car in the field or in railroad car repair areas where suitable temperature, climate and conditions are not always possible to achieve the best adhesion and where the freight railroad cars must be cleaned or painted (as described above) prior to such placement. It should also be appreciated that other suitable types of reflective material may be employed in the freight railroad car reflector apparatus of the present invention.
To install the reflector apparatus 50 on an autorack railroad car in accordance with the method of the present invention, the installer simply takes the reflector apparatus and holds it adjacent to the exterior autorack railroad car side wall panel screen in the appropriate position and inserts the fasteners in each of the mounting apertures and through the holes in the side wall panel screen. The autorack railroad car does not have to be cleaned and does not have to be at a certain temperature (such as fifty degrees or above) or in other suitable conditions. This takes a couple of minutes for each side of the autorack railroad car. It should thus be appreciated that each autorack railroad car can be equipped with reflector apparatus (such as in
It should also be appreciated that
It should also be appreciated that the reflector supporter of the present invention can be recessed relative to the rest of the mounting member or have a recessed reflector receiving area to protect the edges of the reflector.
In alternative embodiments, the mounting member is substantially flat without the structural supports. This embodiment can be extruded from a suitable plastic and cut in a conventional manner. In certain such embodiments, the mounting apertures can be stamped out of the mounting sections in a conventional manner. It should thus be appreciated that the reflector apparatus of the embodiment of
It should further be appreciated that there are many different freight cars and the present invention is configured to be employed for each different type.
This embodiment includes attachment mechanisms in the form of circular weld washers 170a and 170b mounted in the mounting apertures 160a and 160b, respectively. The weld washers may be any suitable shape and any suitable material such as steel, aluminum or another metal. The weld washers 170a and 170b are molded into and thus integrally formed with the mounting sections 158a and 158b respectively during the molding process. Each weld washer illustrated has a centrally located aperture for facilitating the welding process. It should be appreciated that the weld washers may be otherwise suitably formed and shaped to facilitate the welding process. This facilitates easy and quick attachment of the reflector apparatus 150 to the freight railroad car in accordance with the method of the present invention. It should also be appreciated that to account for expansion and contraction of the plastic mounting member, the mounting aperture for the in-molded weld washer or other attachment mechanism may be oval or otherwise suitably shaped. In one such embodiment, the weld washer is maintained in the mounting aperture by the configuration of the mounting section in a movable or free floating manner to account for expansion and contraction.
More specifically, to install the reflector apparatus 150 on freight railroad car, the installer simply takes the reflector apparatus 150 and holds it adjacent to the freight railroad car exterior side wall in the appropriate position and welds each weld washer to the side wall. Because the weld washers 170a and 170b are integrally formed or molded in the mounting sections 158a and 158b respectively, the installer does not need to separately hold the reflector apparatus and weld washers. This facilitates easy and quick attachment of the reflective material to the freight railroad car in accordance with the method of the present invention. Additionally, the freight railroad car does not have to be cleaned and does not have to be at a certain temperature. While the welding process may take a couple of minutes for each reflector apparatus, this process is significantly shorter than the current cleaning processes mentioned above. It should thus be appreciated that each freight railroad car can be equipped with the reflector apparatus much easier and quicker than directly applying reflective tape to the freight railroad car. The welding also prevents the freight railroad car reflector from being easily removed from the freight railroad car (i.e., the welding forms a bond between the railroad car reflector and the freight car.)
The reflector apparatus 150 may be made from any suitable material(s). The mounting member or base 152 may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 154 of the reflector apparatus 150 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. The adhesive backed reflective tape can be placed on the reflector supporter in a controlled environment, as mentioned above, such that maximum adhesive properties are achieved. This provides a great advantage over directly placing the reflective tape on the freight railroad car in the field or in railroad car repair areas where a suitable temperature, climate and other conditions are not always possible to achieve the best adhesion and where the freight railroad cars must be cleaned or painted (as described above) prior to such placement. It should also be appreciated that other suitable types of reflective material may be employed in the freight railroad car reflector apparatus of the present invention.
It should also be appreciated that
The reflector apparatus 250 may be made from any suitable material(s). The mounting member or base may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 254 of the reflector apparatus 250 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material may be employed in the freight railroad car reflector apparatus of the present invention.
The freight railroad car reflector apparatus 250 is different from the freight railroad car reflector apparatus 150 at least in the shape of the outer border, air deflector or air foil 274. This alternative shape also prevents peeling of the reflector material from the mounting member 252. Because the air deflector or air foil is along all of the edges, the air deflector works to protect the leading edge whether the reflector apparatus 250 is placed in a vertical or horizontal position. It should also be appreciated that the mounting member or base 252 may have other structural supports to provide substantial rigidity to the mounting member or base 252 and the entire reflector apparatus 250. It should be appreciated that any suitable structural supports may be employed in the reflector apparatus to provide such rigidity.
The freight railroad car reflector apparatus 350 is different from the freight railroad car reflector apparatus 150 in that fasteners or attachment mechanisms such as the weld washers are not molded into or integrally formed with the mounting sections 358a and 358b. To install the reflector apparatus 350 on freight railroad car in accordance with one embodiment of the present invention, the installer takes the reflector apparatus 350 and holds it adjacent to the freight railroad car exterior side wall or frame in the appropriate position, positions the attachment mechanism such as a weld washer in one of the mounting apertures and welds the weld washer to the freight railroad car. The installer repeats this process for each mounting aperture. It should be appreciated that in this embodiment and in the other embodiments discussed herein, the number, configuration and arrangement of mounting apertures may vary.
The reflector apparatus 350 may be made from any suitable material(s). The mounting member or base may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 354 of the reflector apparatus 350 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material or reflectors may be employed in the freight railroad car reflector apparatus of the present invention.
It should also be appreciated that
The freight railroad car reflector apparatus 450 is different from the freight railroad car reflector apparatus 150 in that the weld washers are not molded into the mounting sections 458a and 458b. The shapes of the mounting sections are also different for the reason discussed below.
The reflector apparatus 450 may be made from any suitable material. The mounting member may be any suitable type of material such as a molded plastic or a stamped metal. In one embodiment, the mounting member 452 is specifically configured to be extruded. The mounting apertures 460a and 460b are stamped in the mounting sections 458a and 458b. In the extrusion process, several mounting members are formed in a single extrusion and are then cut or separated. This separation process forms the straight edge along each end of the mounting member. The structure illustrated has the air deflectors/structural supports 474a and 474b along opposing sides of the mounting member as discussed below. It should be appreciated that a different embodiment may be extruded in a transverse direction to provide the air deflectors/structural supports at the ends of the mounting members.
The reflector 454 of the reflector apparatus 450 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material or reflectors may be employed in the freight railroad car reflector apparatus of the present invention.
It should be appreciated that
The mounting sections 558a and 558b respectively define mounting apertures 560a and 560b for facilitating attachment of the reflector apparatus 550 to the freight railroad car as discussed below.
The reflector apparatus 550 may be made from any suitable material(s). The mounting member or base may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 554 of the reflector apparatus 550 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material or reflectors may be employed in the freight railroad car reflector apparatus of the present invention.
This reflector apparatus is provided in three separate parts for installation. More particularly, the reflector is not attached to the reflector supporter 556 of the mounting member 552 until installation. The installer uses the weld washers to attach the mounting member 552 to the freight railroad car and then attaches the reflector 554 to the reflector supporter 556. The reflector 556 thus covers the weld washers.
It should also be appreciated that
The mounting sections 658a and 658b respectively define oval mounting apertures 660a and 660b for facilitating attachment of the reflector apparatus 650 to the freight railroad car as discussed below.

The reflector 854 of the reflector apparatus 850 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material or reflectors may be employed in the freight railroad car reflector apparatus of the present invention. Specifically, in this embodiment, the reflector may be a plastic reflector supported by the reflector supporter.
It should also be appreciated that
The mounting sections 958a and 958b respectively define mounting apertures 960a and 960b for facilitating attachment of the reflector apparatus 950 to the freight railroad car.
The reflector apparatus 950 may be made from any suitable material(s). The mounting member or base may be any suitable type of material such as a molded plastic or a stamped metal.

It should also be appreciated that
The reflector apparatus 1050 may be made from any suitable material(s). The mounting member or base may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 1054 of the reflector apparatus 1050 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material or reflectors may be employed in the freight railroad car reflector apparatus of the present invention. Specifically, in this embodiment, the reflector may be a plastic reflector supported by the reflector supporter.
It should also be appreciated that
It should be appreciated that in any of the embodiments of the present invention, the reflector apparatus can include a cover mounted over the reflector or the reflector and mounting member to protect the surface of the reflector from scratching or other damage. In one such embodiment, the cover is a clear plastic sheet. In another embodiment the cover includes a clear material molded around the reflector. Other suitable covers may be employed in the reflector apparatus.
The mounting sections 1158a and 1158b respectively define mounting apertures 1160a and 1160b configured for facilitating attachment of the reflector apparatus 1150 to the freight railroad car. The mounting apertures 1160a and 1160b are suitably sized to receive a portion of weld washers 1170a and 1170b. A portion of each of the weld washers 1170a and 1170b respectively extend beyond the mounting apertures 1160a and 1160b to provide a sufficient purchase area to enable the weld washers to maintain the mounting sections 1158a and 1158b (and the entire reflector apparatus 1150) to the freight railroad car when the weld washers are welded to the freight railroad car.
The mounting sections 1158a and 1158b have weld washer guides 1161a and 1161b in the form of outwardly extending guide walls, each of which has a first wall portion on a first side of mounting aperture 1160a or 1160b, and a second wall portion on a second side of mounting aperture 1160a or 1160b; and weld washer holders or tabs 1162a and 1162b, each of which extends from a free end of at least one of the first and second wall portions, i.e. extending from the top edge of guide 1161a or 1161b. The mounting sections 1158a and 1158b also have curved walls that are located inside and perpendicular to guides 1161a and 1161b, and that define the perimeters of mounting apertures 1160a and 1160b. The mounting sections are configured so as to allow an installer to place the weld washers 1170a and 1170b in the mounting apertures 1160a and 1160b, and which removably hold or maintain the weld washers, to prevent the weld washers 1170a and 1170b from falling out of the mounting apertures prior to or during the welding process. The guides 1161a and 1161b and weld washer holders or tabs 1162a and 1162b thus coact to maintain the weld washers 1170a and 1170b in position for welding. In one embodiment as illustrated, the weld washer guides 1161a and 1161b respectively extend outwardly or transversely from the exterior surface of the mounting sections 1158a and 1158b surrounding the mounting apertures, and the holders or tabs 1162a and 1162b respectively extend from the guides 1161a and 1161b substantially parallel to the mounting apertures. This configuration allows the guide and holder to maintain the weld washer in the mounting aperture. After the weld washers are welded to the freight railroad car, this configuration enables the reflector apparatus to slide back and forth within the area defined by the guide to allow for expansion and contraction.
The reflector apparatus 1150 can be in provided in three separate parts for installation (i.e., the reflector apparatus and the two weld washers removed from the mounting sections) in accordance with the method of the present invention. The installer inserts the weld washers 1170a and 1170b into the apertures of the mounting members 1158a and 1158b and welds them to the freight railroad car in accordance with the method of the present invention.
It should also be appreciated that the mounting member or base 1152 may have structural supports to provide substantial rigidity to the mounting member or base 1152 and the entire reflector apparatus 1150. Any suitable structural supports may be employed in the reflector apparatus to provide such rigidity. The supports of the reflector apparatus 1150 also define an outer raised border, air deflector or air foil 1180. In one embodiment, because the air deflector or air foil is along all of the edges, the air deflector works to protect the leading edge whether the reflector apparatus 1150 is placed in a vertical or horizontal position. This border, air deflector or air foil functions to deflect or redirect wind from engaging the leading edge of the reflector 1154. This prevents peeling of the reflector material from the mounting member 1152.
The reflector apparatus 1150 may be made from any suitable material(s). The mounting member or base may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 1154 of the reflector apparatus 1150 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material or reflectors may be employed in the freight railroad car reflector apparatus of the present invention.
More specifically, railroad car reflector apparatus 1250 includes a mounting member or base 1252, a reflector 1254 attached to a reflector supporter 1256 of the mounting member or base 1252, and mounting sections 1258a and 1258b connected to and extending from the reflector supporter 1256. The mounting sections 1258a and 1258b respectively define mounting apertures 1260a and 1260b suitably sized to receive a portion of weld washers 1270a and 1270b to facilitate attachment of the reflector apparatus 1250 to the freight railroad car. The weld washers 1270a and 1270b respectively extend beyond the mounting apertures 1260a and 1260b to provide a sufficient purchase area to enable the weld washers to maintain the mounting sections 1258a and 1258b (and the entire reflector apparatus 1250) to the freight railroad car when the weld washers are welded to the freight railroad car.
The mounting sections 1258a and 1258b have weld washer guides 1261a and 1261b, weld washer holders or tabs 1262a and 1262b and removable weld washer holders 1275a and 1275b which further hold or maintain the weld washers to prevent the weld washers 1270a and 1270b from falling out of the mounting apertures after assembly and prior to or during the welding process. The guides 1261a and 1261b, the weld washer holders or tabs 1162a and 1162b and the removable weld washer holders 1275a and 1275b coact to maintain the weld washers 1270a and 1270b in position for welding. This reflector apparatus 1250 can be provided fully assembled where the reflector apparatus has the two weld washers attached to the mounting sections. It should be appreciated that the removable weld washer holders 1275a and 1275b maintain the weld washers 1270a and 1270b in position for welding even if the railroad car reflector is placed on the car in a horizontal position. After welding, the removable weld washer holders 1275a and 1275b are removed. This facilitates the movement of the reflector apparatus relative to the stationary (i.e., welded) weld washers to allow for expansion and contraction. The guides 1261(a) and 1261(b) respectively limit the movement of the reflector apparatus.
It should also be appreciated that the mounting member or base 1252 may have structural supports to provide substantial rigidity to the mounting member or base 1252 and the entire reflector apparatus 1250. Any suitable structural supports may be employed in the reflector apparatus to provide such rigidity. The supports of the reflector apparatus 1250 also define an outer raised border, air deflector or air foil 1280. In one embodiment, because the air deflector or air foil is along all of the edges, the air deflector works to protect the leading edge whether the reflector apparatus 1250 is placed in a vertical or horizontal position. This border, air deflector or air foil functions to deflect or redirect wind from engaging the leading edge of the reflector 1254. This prevents peeling of the reflector material from the mounting member 1252.
It should also be appreciated that the reflector supporter of the present invention can be recessed relative to the rest of the mounting member to protect the edges of the reflector material.
The reflector apparatus 1250 may be made from any suitable material(s). The mounting member or base may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 1254 of the reflector apparatus 1250 is in one embodiment a suitable adhesive backed reflective tape such as the reflective tape commercially available as mentioned above. It should also be appreciated that other suitable types of reflective material or reflectors may be employed in the railroad car reflector apparatus of the present invention. The removable weld washer holders 1275a and 1275b in one embodiment are made from a single sided adhesive tape.
It should be appreciated that the railroad car reflector or reflector apparatus of the present invention can be formed with any suitable number or combination of attachment mechanism, guides, and removable or non-removable holders. For instance, in one embodiment, a plurality of holders are positioned around the mounting aperture. In another embodiment, a plurality of removable holders are employed to maintain the attachment mechanism or weld washer in the mounting aperture. It should also be appreciated that the configuration, shape and size of the guides and holders may vary.
The reflector apparatus 1350 also includes suitable fasteners or attachment mechanisms for attaching the mounting member or base 1352 to the freight railroad car such as the fasteners or attachment mechanisms discussed above in regard to
Each mounting section defines a mounting aperture which is shaped and sized to receive the fastener in multiple positions. In the illustrated embodiment, the mounting apertures 1360a, 1360b, 1360c and 1360d are each symmetrically shaped to facilitate attachment of the reflector apparatus in a horizontal or substantially horizontal position relative to the autorack railroad car.
The reflector apparatus 1350 may be made from any suitable material(s). The mounting member or base 1352 may be any suitable type of material such as a molded plastic or a stamped metal. The reflector 1354 of the reflector apparatus 1350 is in one embodiment a suitable adhesive backed reflective tape such as a reflective tape commercially available as mentioned above.
To install the reflector apparatus 1350 on autorack railroad car, the installer simply takes the reflector apparatus and holds it adjacent to the exterior autorack railroad car side wall panel screen in the appropriate position and inserts the fasteners in each of the mounting apertures and through the holes in the side wall panel screen.
It should also be appreciated that the mounting member or base 1352 may have structural supports such as supports or ribs (not shown) to provide substantial rigidity to the mounting member or base 1352 and the entire reflector apparatus 1350. Any suitable structural supports may be employed in the reflector apparatus to provide such rigidity. The supports of the reflector apparatus 1350 define an outer raised border, air deflector or air foil 1380. This border, air deflector or air foil 1380 functions to deflect or redirect wind from engaging the leading edge of the reflector 1354. This prevents peeling of the reflector from the mounting member 1352. It should also be appreciated that the reflector supporter of the present invention can be recessed relative to the rest of the mounting member to protect the edges of the reflector.
In an alternative embodiment, the installer can drill a hole in the freight railroad car aligned with the mounting aperture and use a blind rivet to attach the mounting member to the freight railroad car instead of welding. In this embodiment, the mounting apertures may be considerably smaller. In one such embodiment, a weld washer with a smaller hole is used in conjunction with the rivet to provide a sufficiently sized purchase area.
It should be appreciated that the mounting member provides a contrast to the reflector in one embodiment to make the reflector more viewable. In one such embodiment, the mounting member is black and the reflector is yellow.
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
This application is a non-provisional application of, claims the benefit of and priority to U.S. Provisional Application Ser. No. 60/664,303, filed Mar. 22, 2005, the entire contents of which are incorporated herein.
