- This movement of the brake assembly 130 also disengages the key hole 106 of the motor brake 107 from the motor key 104 of the motor 102 , thus resulting in free rotation of the drive shaft of the motor 102 .
- slide-out mechanisms operate in a fashion similar to the mechanism described herein.

Description
- This application claims priority to U.S. provisional application Ser. No. 60/430,425 filed on Dec. 2, 2002 entitled Removable Motor Brake For Use With Vehicle Slide Out, the contents of which are hereby incorporated herein by reference.
- A large number of recreational vehicles and recreational trailers (collectively “RV's”) currently include compartments that are moved outwardly from the walls of the RV so as to expand the internal living space of the RV. These compartments are typically referred to as slide-outs. It is not uncommon for such slide-outs to substantially enlarge a bedroom or a kitchen area of the RV.
- Many of the slide-outs are operated on the RV with an electric motor that is connected to the structural framework of the slide-out. When energized, the motor causes the framework to move along a guide or pathway until the framework extends to its fullest extension, at which point the motor is then deenergized.
- Such motors typically include a brake mechanism as an integral part of the motor such that when the motor ceases its operation, the brake automatically engages the slide-out so as to ensure no further movement of the framework of the slide-out. The engagement of this brake, however, can pose problems to the user in those instances when the motor inadvertently fails or in the event electrical power to the motor is unexpectedly interrupted. In those circumstances, the user may desire to move the slide-out manually but will be unable to do so unless the brake is first disengaged. As a result, there is a need for a manual mechanism that enables the user to quickly and easily disengage the brake from the motor so that the user may then manually move the slide-out.
- In accordance with this need, the present invention contemplates a motor and brake assembly described in preferred embodiments below. The assembly includes a motor and a disengaging mechanism that is mounted thereon.
- It is an object of the present invention to provide a slide-out motor brake which may be manually disengaged.
- It is a further object of the present invention to provide an inexpensive motor brake which may be easily and reliably disengaged.
- These and other objects not specifically enumerated here that are achieved by the present invention will become evident as more fully described below.

FIG. 1 , a preferred embodiment of the present invention is depicted. Abraking motor assembly 100 is made up of a slide-outmotor 102 and aremovable braking assembly 130. Themotor power cables 126 extend out the backside of the slide-outmotor 102, to a control switch and power supply (not shown). A motor key 104 is located on the backside ofmotor 102, near themotor power cables 126. The motor key 104 is coupled to the drive shaft within the motor. As the motor is energized, the drive shaft rotates. And as the drive shaft rotates, so does the motor key 104. - A variety of motors may be used, so long as the motor is capable of driving the slide-out mechanism on the vehicle and so long as it has a drive shaft coupled to a motor key. The key serves as an engagement surface for said external brake.
- The
brake assembly 130 is best illustrated inFIGS. 1 and 2 . A preferred embodiment includes amotor mount 108, abrake housing 110, and amotor brake 107. Anexemplary motor brake 107 for use in a preferred embodiment is a brake manufactured by Steams a division of Rexnord Industries of Wisconsin, modelnumber #b 130 OBJY2. - The
motor mount 108 is a cylindrical member having a plurality of screw holes disposed on the periphery of the cylindrical member. The cylindrical member extends over the barrel of themotor 102, as best seen inFIG. 3 .Mounting screws 114 screw into the plurality of screw holes and further into the barrel of themotor 102, securing themotor mount 108 to the motor. - The
brake housing 110 has a cylindrical shape, fitting over both themotor 102 barrel and themotor mount 108. The brake housing 110 locks to themotor mount 108 bymultiple locking pins 116 which extend throughpin holes 128 in the flange ofmotor mount 108. Themotor mount 108 andbrake housing 110 are further secured together by the force ofsprings 112 which, when attached to the flanges of each member are held in tension, thus compressing themotor mount 108 and thebrake housing 110 together. - The
motor brake 107 can best be seen inFIG. 1 with akey hole 106 andbrake power wires 124 extending out the back. Themotor brake 107 is mounted to the interior ofbrake housing 110 by mountingbolts 120 and mountingnuts 122. - When assembled, motor key 104 is received into
key hole 106 of themotor brake 107. When themotor 102 is unenergized, thebrake 107 defaults to the locked position, preventing thekey hole 106 from rotational movement and thus preventing movement of the motor drive shaft. As a result, the slide-out mechanism is prevented from movement. When themotor 102 is energized, themotor brake 107 is caused to unlock, thus allowing thekeyhole 106 to freely rotate with the rotation of the key 104. This then allows free rotation of the motor drive shaft so as to move the slide-out mechanism inwardly or outwardly from the vehicle. In summary, so long as the key 104 is engaged in thekey hole 106 of themotor 102, the state of thebrake 107 will then dictate whether the slide-out mechanism can be moved by the drive shaft of themotor 102. -
Brake assembly 130 may be positioned in an engaged and disengaged position.FIG. 2 illustrates thebrake assembly 130 in an engaged position and shows that the engaged position is achieved when thelocking pins 116 are positioned within thepin holes 128 in themotor mount 108, preventing rotation of thebrake housing 110. In this engaged position, the key 104 of themotor 102 will be engaged within thekey hole 106 of thebrake 107. -
FIG. 3 illustrates the unengaged position of this embodiment. Thebrake assembly 130 is disengaged by manually pulling thebrake housing 110 directly away from themotor mount 108 until thelocking pins 116 are completely removed from thepin holes 128. Thebrake housing 110 is then rotated in either direction. Such rotation prevents the brake assembly from moving back to the engaged position, since thepins 116 and thepin holes 128 are no longer aligned. This movement of thebrake assembly 130 also disengages thekey hole 106 of themotor brake 107 from the motor key 104 of themotor 102, thus resulting in free rotation of the drive shaft of themotor 102. - Many slide-out mechanisms operate in a fashion similar to the mechanism described herein. Generally these mechanisms have sliding members that slide back and forth on nonmoving members or vehicle structural supports. A slide-out room secures to these moving members, allowing for extension and retraction from the main body of the vehicle.
-
FIGS. 4 through 7 illustrate a preferred embodiment of such a slide-outmechanism 200 mentioned above. Outerstructural members 208 support most of the load of a slide-out room (not shown), while innerstructural member 206 provides a mounting area for thebraking motor assembly 100. This mounting area can best be seen inFIG. 5 where themotor 102 has been removed to show adrive gear 212 and ashaft gear 210, as well as inFIG. 6 where amotor gear housing 207 encloses this gearing while securing thebraking motor assembly 100. - The slide-out room (not shown) sits on a top surface of sliding
rams 204, being further fastened to eachram 204 with bolts. Therams 204, in turn, are slidably coupled to the top side of the outerstructural members 204, extending a substantial length of each. Thus, therams 204 allow a slide-out room to easily extend out from the main body of a vehicle. - A present preferred embodiment of the slide-out mechanism is driven by the
braking motor assembly 100, mounted to the innerstructural member 206. Thebraking motor assembly 100 drives the entire slide-outmechanism 200 from the innerstructural member 206 by a series of distribution gears and shafts. - Beginning with the
braking motor assembly 100, the drive shaft ofmotor 102 is coupled to drivegear 212.Drive gear 212 meshes withshaft gear 210, located on thecross shaft 202. Thecross shaft 202 is responsible for transferring the rotational energy of themotor 102 to each of the sliding rams 204. Rotational movement is further transferred to thecross shaft 202 since theshaft gear 210 is mounted around thecross shaft 202. - The
cross shaft 202 is rotatably mounted within both the outerstructural members 208 and innerstructural member 206. As thecross shaft 202 rotates, it drivesram gear 216, as best seen inFIG. 8 . Positioned underneath the slidingram 204 isram gear 216, allowing the gear to mesh withram gear track 214. Theram gear track 214 extends the length of the underside of each sliding ram and in this manner allows theram gear 216 to move the slidingram 204 and thus the slide-out room to an extended or retracted position. - Another popular slide-out mechanism design can be seen in U.S. Pat. No. 6,428,073, the contents of which are hereby incorporated by reference. It is understood that the present invention may utilize a variety of different slide-out mechanisms as long as they are motorized or are capable of becoming motorized.
- A disengaging mechanism of the preferred embodiment operates as follows: In the event the user determines that the
motor 102 is not usable (e.g. loss of power, motor failure, etc.) and thebrake 107 must be disengaged, the user simply pulls on the brake housing 110 (against the force of the springs 112) in a direction away from themotor 102 until the motor key 104 on the drive shaft of the motor disengages thebrake keyhole 106 of thebrake 107. After pulling a certain distance, thepins 116 will be withdrawn from theircorresponding pin hole 128 in the flange of themotor mount 108. Next, the user will rotate the brake housing 110 a sufficient distance (either clockwise or counter clockwise) so that neither the brakekey hole 106 nor theelongated pins 116 are in alignment with the motor key 104 and pinholes 128 respectively. - The user then releases the grip on the
brake housing 110 causing the tip of thepin 116 to engage the flange on the motor mount and thereby preventing thebrake assembly 130 from reengaging with themotor 102. With themotor 102 now being free from thebrake 107, the user then is able to manually move the slide-out framework without further resistance from the motor brake. - The user reengages the
brake assembly 130 by again pulling the brake housing 110 (against the force of the springs 112) in a direction away from themotor 102 until the locking pins 116 no longer apply pressure to the flange ofmotor mount 108. The user then rotates thebrake housing 110 until the locking pins 116 are once again aligned with their corresponding pin holes 128. Next, the user releases thebrake assembly 130, allowing lockingpins 116 to enter the corresponding pin holes 116 andbrake housing 110 to move closer tomotor mount 108. As thebrake housing 110 moves closer to themotor 102, themotor brake 107 also moves closer to themotor 102 untilkey hole 106 reengages with key 104. Once thekey hole 106 has reengaged withkey 106, brakingmotor assembly 100 once again operates as mentioned above, allowing thebrake 107 to lock themotor 102 when themotor 102 is powered down, thus locking the slide-out room in place when not being extended or withdrawn. - Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
