1. Field of the Invention
The present invention relates generally to a roller system and more specifically it relates to a garage door roller system for preventing damage to a vehicle or garage door due to obstructions when the door is opening or closing.
2. Description of the Related Art
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Garage doors are in use throughout the world. Very often, garage doors are operated either from within the vehicle itself or from a separate controller, such as mounted to a wall. In either case, it is very common for one to inadvertently open or close a garage door when there is some sort of obstruction which will block it from fully opening or closing. To prevent injury, most garage doors sense torque levels and will reverse the garage door from opening or closing when a certain level of torque is detected. However, at the point when torque is detected, the garage door will often have already contacted an obstruction and, in many cases, either damages the obstruction or the garage door itself. Many garage doors include a steel arm which connects a carriage of the opener with the garage door itself. Very often, this steel arm extends downwardly and has a lower overhead clearance than any other part of the garage door. In situations in which the steel arm contacts another object, such as a hatch of a vehicle, serious damage can be done. Vehicles often have a high profile, particularly if they have a rear hatch lift gate that when open, exceeds the clearance between the opener arm and the vehicle hatch/lift gate, resulting in damage if contact is made.
It is very common to accidentally leave a hatch or lift gate of a vehicle open, such as when emptying groceries, and then forget to close the hatch or lift gate before activating the garage door. In these cases, the steel arm of the garage door will have already damaged the vehicle, such as by leaving a scratch, before a higher torque is detected and the garage door reversed. In fact, the reversal of the garage door can actually cause even more damage to the vehicle since the steel arm will contact the vehicle again on the way back up or down.
Because of the inherent problems with the related art, there is a need for a new and improved garage door roller system for preventing damage due to obstructions when the door is opening or closing.
Provided herein is a garage door roller system which includes a garage door arm which is connected at its upper end to a carriage of a garage door opener. A connector is connected to the garage door arm, with a first portion extending along the garage door arm and a second portion extend away from the garage door arm at a right angle. The second end of the connector is connected to a garage door such as by a bracket. One or more rollers are freely rotatable about the lower end of the garage door arm, with the lower ends of the rollers being positioned lower than the lower end of the garage door arm. The rollers are adapted to roll across any obstruction present when the garage door is opening or closing to prevent damage to the obstruction as well as the garage door arm.
There has thus been outlined, rather broadly, some of the features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction or to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
Various other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,
The figures illustrate that the obstruction 60 comprises a vehicle or a hatch 62. It should be appreciated that the present invention may function with various types of obstructions 60 and thus the scope of the present invention should not be limited to vehicles 60 with hatches 62. For example, the present invention would function with any obstruction 60 of high enough clearance to block normal operation of the garage door 17, such as but not limited to boats, airplanes, boxes, shelving, boxes, and the like.
As best shown in

As shown in
As shown, the connector 30 may comprise a first portion 33 extending in a first direction and a second portion 34 extending in a second direction. When connected to the garage door arm 20 as shown in
In some embodiments, the connector 30 will comprise an L-shaped configuration in which the second portion 34 extends at a right angle with respect to the first portion 33. Other angles may be utilized for different embodiments of the present invention, and thus the exemplary configuration shown in the figures should not be construed as limiting on the scope of the present invention.
The first end 31 of the connector 30 will generally be on the first portion 33 and the second end 32 of the connector 30 will generally be on the second portion 34 as shown in
The second opening 36 of the connector 30 is located at or near its second end 32 as shown in
In many embodiments, the connector 30 will include a second connector opening 38 which is adapted to be aligned with the first connector opening 26b of the garage door arm 20 to secure the connector 30 against the garage door arm 20. The second connector opening 38 is generally positioned approximately one-quarter of the length up the connector 30 from its second end 32 to its first end 31 as shown in
In most embodiments such as shown in
As shown throughout the figures, the present invention utilizes one or more rollers 40, 42 which are adapted to contact and roll along an obstruction 60 such as a vehicle for prevention of damage to the obstruction 60. While the figures illustrate that the rollers 40, 42 comprise wheels, it should be appreciated that other configurations may be utilized for different applications. In some embodiments, the rollers 40, 42 may comprise rubber bumpers or the like which do not roll, but instead slide along the surface of the obstruction 60. In a preferred embodiment, the rollers 40, 42 comprise wheels made of a rubber or other malleable material which is not likely to damage a surface when rolling across it.
The rollers 40, 44 of the present invention are generally connected to the lower end 22 of the garage door arm 20 for rolling across a surface of an obstruction 60 to prevent damage to the obstruction 60. The rollers 40, 44 will thus preferably each extend below the lower end 22 of the garage door arm 20 such that the rollers 40, 44 prevent the garage door arm 20 or any portion thereof from contacting the obstruction 60.
The figures illustrate usage of a first roller 40 and a second roller 44. More or less rollers 40, 44 may be utilized in different embodiments. An exemplary embodiment in which two rollers 40, 44 are utilized is shown in
In the embodiment shown in
Preferably, an axle 50 is provided which extends through the first roller opening 42 of the first roller 40, the lower opening 24 of the garage door arm 20, and the second roller opening 46 of the second roller 44. The first end 51 of the axle 50 is secured against the outer surface of the first roller 40 while the second end 52 of the axle 50 is secured against the outer surface of the second roller 40. Spacers 54a, 54b may be utilized to ensure that no parts of the rollers 40, 44 are in contact with the garage door arm 20 or connector 30. As shown in
Similarly, optional washers 55a, 55b may be included. A first washer 55a may be positioned between the first end 51 of the axle 50 and the first roller 40 and a second washer 55b may be positioned between the second end 52 of the axle 50 and the second roller 44. A lock nut 56 or other type of fastening device may be utilized to secure the axle 50 in place, such as using threading on the second end 52 of the axle 50 as shown in
In use, the garage door arm 20 is first secured to the carriage 15 of the track 16 of the garage door opener 14 as shown in
At this point, the garage door arm 20 is pivotally connected to the carriage 15 of the garage door opener 14 and the connector 30 is connected to the garage door arm 20. The connector 30 may then be connected to the garage door 17. The second opening 36 of the connector 30 will generally be aligned with a mounting point such as a bracket 18 on the garage door 17 and secured thereto, either pivotally or non-pivotally, with a fastener 12 as shown in
With the garage door arm 20 and connector 30 fully installed as shown in
In either case, an axle 50 is extended through both rollers 40, 44 and the lower opening 24 on the lower end 22 of the garage door arm 20 such that the rollers 40, 44 may freely rotate about the lower end 22 of the garage door arm 20 as shown in
With the present invention fully assembled and installed, the garage door 17 may be used as normal. In a situation in which an obstruction 60 is present when the garage door 17 is opening or closing, the rollers 40, 44 will roll across the obstruction 60 and thus prevent any damage thereto. For example, if the hatch 62 of a vehicle 60 is left open when the garage door 17 is opening or closing, the rollers 40, 44 will push the hatch 62 down slightly and pass harmlessly over both the hatch 62 and the vehicle 60 without causing any damage as shown in
If the rollers 40, 44 come across a structure which increases torque, such as contacting a luggage rack 64 as shown in
