Roller guide 10 is secured to an elevator car. A roller guide for improving the movement of an elevator car on T-shaped guide rails. Since the two end pieces 56 a and 56 b have mirror image configurations, it is sufficient to describe only the end piece 56 a in greater detail below. The length of the channel 87 and the length of the plug-type pin 81 approximately correspond to the diameter of the spherical head 72. The second axis compensates for the angular adjustment of the plug-type element of the coupling device relative to the plug-type element of the guide rail.
This book covers the most important topics related to patents and patent applications, gives you a step-by-step roadmap of patent prosecution, and also explains the international patent applications as well as the recent changes that the America Invents Act brought. The guide groove 16 begins at a rear window shelf 17 arranged behind the back rest 11 and extends adjacent to the side edge of the window. Furthermore, a lubricant is typically applied to the guide rails of an elevator system with an automatic mechanical oiling device. September 6, 2005 Ulriksen et al. A provisional application is a quick and inexpensive way for inventors to establish a U.
The window shade of the invention comprises a windup shaft that is rotatably supported in the vehicle. The thrust elements 31 and 32 can now be inserted through the channel 87. Alternately, a plurality of flexible plates can be stacked and used to spring-bias each wheel. The guide groove for the pull bar preferably continues a certain distance into the coupling device. The spherical head 72 contains a channel 87 that is configured complementary to the plug-type pin and originates at the end face 86.
The roller guide, when installed, is dimensioned to meet the required safety tolerances of the elevator and allow for safe operation of the elevator safeties. Since the spring drive 21 situated in the windup shaft 19 has a constant tendency to wind up the roller blind web 15 on the windup shaft 19, the guide pieces 23, 24 are pulled into the shaft 73 in the direction of the lower end of the slot 28 with a corresponding force. A very compact design is achieved if the guide groove continues through the first plug-type element. The distal edge of the roller blind web relative to the windup shaft is provided with a pull bar in order to place the roller blind web in front of the rear window. The base unit 55 includes two end pieces 56 a and 56 b, as well as a connecting bridge 57 on which the geared motor 35 is mounted. The unit thus obtained can be delivered to the motor vehicle assembly line by the manufacturer of the window shade and quickly and easily installed underneath the rear window shelf. The axis of the bearing surface 68 is, as shown, aligned such that it coincides with the direction of the adjacent end of the guide rail 16 once the guide rail 16 is seated without play.
The coupling device carries a shaft that lies adjacent to the spherical head, and the diameter of which is smaller than the diameter of the spherical head. August 6, 2002 Swink et al. The end piece 56 a is illustrated in a highly schematic manner in the drawings, in particular, with respect to the fact that not all of the reinforcing ribs are shown so as not to complicate the drawing with details that are not essential for understanding the invention. An elastically bendable stud 64 projects from the bottom section 63 in front of the end of the side wall 60, with the upper end of said stud being integrally connected to the mounting 59 for the coupling device 58. The desired articulation can be easily achieved by configuring the mounting in the shape of a spherical socket, the inner surface of which consists of a spherical zone that is open in the direction parallel to the longitudinal axis of the windup shaft in one region. The wheels of the elevator car roller guide are spring-biased toward each other to engage the sides of the nose portion of the T-shaped guide rail. Inserting tabs 23 on the opposing end of a leaf spring into slots 21 on the second member of a pair of support members biases the leaf spring.
The elastically bendable guide tube 29 is mounted on the far end of the shaft 73, relative to the spherical head 72, with the guide tube extending past the rear side of the end piece 56 a in the installed state, and being guided in a fork 76 provided on the outer side of the side wall 60 at the transition to the bottom section 63. The driving motor 35 can now be mounted on the underside of the connecting bridge 57, and the guide tubes 29 and 30 are connected to the gear housing 35 as shown. However, such a solution is limited to embodiments in which the respective guide rail forms a part that is constructed essentially independent of the side trim. Between the B-column 3 and the C-column 5, a right rear door 7 is conventionally hinged to the B-column 3. The protruding arm of support member 20 contains slots 21.
Thedisplays various programs and initiatives that are available to applicants during each phase of the application process. Utilizing a hinge to connect the guide rails to a guide rail stub that is already rigidly connected to the windup shaft or its supporting device by the manufacturer of the rear window shade has already been attempted. In this case, both sections transition into each other via a cone or conical surface. Maeda describes such a system in U. The patent grant is mailed on the issue date of the patent. The design of the individual element defines the direction and the position in which the guide rail is connected to the base unit. This type of connection cannot be utilized for rear window shades in which the guide rail forms an integral or integrated component of the interior trim of the motor vehicle, for example, the trim for the rear column that borders the rear window.
February 8, 2005 Hudoba et al. When the geared motor 33 is actuated, the thrust elements 31, 32 are selectively extended or retracted. Sliding guides are also a source of excessive noise during operation of the elevator. The two sections 82 and 83 transition into each other via a conical surface 84. Another limit stop 67 is situated on the opposite side and cooperates with the mounting 59.
