DETAILED DESCRIPTION OF THE EMBODIMENTS
Referring now to the drawings wherein like reference numbers designate identical or corresponding parts throughout the several views and more particularly to FIG. 1 thereof, there is illustrated a frame for leveling and shifting forward sunroof glass.
FIG. 1 illustrates a frame 1 having a first part and a second part. The first part having a plurality of suction cups 2A attached thereto which are designed to attach to the sunroof glass and the second part also having a plurality of suction cups 2B attached thereto which are designed to attach to the vehicle body. Also attached to the first part of the frame 1 are guide bars 3A and 3B. Attached to guide bars 3A and 3B are shims 4A and 4B. The shims 4A and 4B may be made of Plastic (UHMW) material or some other suitable material which prevents damage to sunroof part of the automobile when implemented. In addition, the shims 4A and 4B may be of varying lengths, or of the same length. In addition, the thicknesses of the shims are the same value, such as 3.2 mm. Also attached to the first part of the frame 1 are datuming blocks 5A and 5B which locate the frame 1 correctly on the vehicle roof panel by lining up the longer sides of the frame 1 (side A) with a sunroof body opening. Also attached to the frame 1 are side datuming blocks 6A and 6B which line up the shorter sides of the frame 1 (side B) with the corresponding side of the sunroof body opening. The datuming blocks are precise components which may be made of a hard plastic or some other material which is suitable to support the function of the blocks (e.g. lining up the frame 1 with the opening). Although the datuming blocks 5A-6B are shown in the drawings as being disk shaped, the datuming blocks 5A-6B can also be square or partially spherical or any other suitable shape.
In addition, attached to the frame are lighting elements 7 and positioning blocks 13.
FIG. 2 illustrates closer view of guide bar 3B, shim 4B and datuming block 5B. As is shown in FIG. 2, the frame 1 is positioned with the sunroof opening 10 of the vehicle roof 17 in which the sunroof 18 is disposed using the datuming blocks 5A and 5B. The datuming block 5B has an outside surface 5B-A which is in contact with the edge of the body opening 10. In addition, spring 15 allows the datuming block 5B to move down such that a bottom surface contacts the sunroof 18 or the gasket 12 or both. Positioning block 13 contacts the roof the vehicle 17 and also includes spring 16 which allows the block 13 to have a bottom surface which contacts the roof 17. Block 13 allows frame 1 (end effector) to rest on the vehicle roof 17 without causing any scratch marks. Springs 16 above the block 13 are provided to adjust levelness. Suction cup 2B holds the frame 1 in position on the roof. Also connected to the frame 1 is the guide bar 3B to which is connected the shim 4B. Connected to the shim 4B is pneumatic cylinder 14 which moves the shim 4B up and down. When the cylinder 14 is extended the shim 4B moves into space 11 between the sunroof 18 and the gasket 12. As a result of the shim 4B being extended into the space 11, the sunroof 18 is shifting forward by the thickness of the shim, e.g. 3.2 mm in the above noted example.
FIG. 3 illustrates the position of the shim 4B after the shim 4B has extended into the space 11. As a result of the insertion of shim 4B into the space 11, the sunroof 10 moves in the direction of arrow 20. Block 13 maintains its position on the roof of the vehicle 17.
FIGS. 4A-B illustrate a wide view showing the process whereby the frame 1 is moved onto the vehicle 17. As is illustrated in FIG. 4A, the frame 1 is connected to a retractable arm 31 which connected to a base 30. Once the vehicle is moved into area 32, the frame 1 is positioned onto the vehicle 17 such that the suction cups 2 of the frame 1 are in contact with the sunroof 18. In addition, the frame is positioned such that datuming blocks 5A&B edge of the body opening 10 in which the sunroof 18 is placed.
FIG. 5 illustrates the raku seat 40 which moves into the inside of the vehicle 17 and supports an installer during the sunroof leveling and shim insertion operation. The raku seat 40 is a sliding seat—a means of easy and quick access to sections of vehicle which otherwise would be difficult to approach ergonomically.
FIG. 6A illustrates an example of the control panel for the present system. Item 1000 is a lift up and down button which moves the frame away and towards the body of the vehicle 17. 1001 is an ON and OFF switch which turns ON and OFF the system. 1002 turns on the vacuum for leveling method procedure switch 1003 activates the shim 4A/B insertion. This control can also be done via computer or display or touch screen display which includes inputs to lift up and down the device, turn ON and OFF the device or switch the vacuum or activate the shim 4A/B insertion. FIG. 6B illustrates the example of light indicators which provide indications of the readiness states of the device. Element 1110 indicates shim insertion OK condition. Green light 1112 indicates vacuum OK condition and red light 1111 indicates no vacuum condition.
Shown in FIG. 7 is a pressure regulator with a drain and a three-port two-way valve 100 fluidly connected to two-way three-port push button spring return values 110 and 111.

FIG. 13 describes an embodiment of the disclosure in which a method of using the disclosure is shown. In FIG. 15 step S1 illustrates the first step of an installer operating the frame 1 to position the frame 1 on the vehicle roof 17. Datuming blocks 5A&B enable the installer to position side A of the frame correctly with respect to the body opening 10 in the vehicle roof. In addition, blocks 6A and 6B facilitate the positioning of the frame 1 in the body opening 10 of the sunroof in the vehicle 17.
The installer then, in step S2 and in a sitting position, for example, on the raku seat 40, performs different assembly and installation jobs inside the vehicle 17. For example, tightening the screws which hold the sunroof assembly 18 in the vehicle 18 or aligning the sunroof 18.
In step S3, the frame 1 is then attached to the sunroof glass 18. Once the frame 1 is attached to the sunroof glass, in step S4, a shim 4A/B is inserted into the space 11 between the gasket 12 and the edge of the body opening 10. The insertion of the shim 4A/B in step S4 is a dual stage shim insertion. First, low pressure cylinders (330 & 331) extend shims just above the roof surface and the installer aligns the frame 1 with the body opening 10. The shims 4A/B are then fully extended in-between the body opening 10 and the sunroof gasket 12 to be in a position to shift the glass forward.
In step S5, the frame 1 and the shim 4A/B moves/shifts the sunroof glass 18 forward.
Once the step of moving the sunroof glass 18 forward has completed, in step S6, a leveling process is performed which levels the glass being held by the vacuum powered suction cups. By shifting the glass forward before the levelness procedure, issues related to pinching of the sunroof gasket 12 getting caught in the body opening are avoided.
In the leveling process the suction cups 2A hold the glass 18 by vacuum. The sunroof leveling process entails pulling sunroof glass up using vacuum powered suction cups and pneumatic cylinders so as to achieve glass positioning as per vehicle specifications e.g., 0.5+/−1 mm in reference to vehicle roof surface.
In the embodiment in which suction cups 22 are also attached to the sunroof glass 18, a pressure switch senses vacuum and actuates cylinders and the cylinders (330 & 331) thus create forward shift.
The shim insertion leveling system can include a control module or display module which indicates the level of readiness of the device as well as enables the user to utilize the device.
The shim insertion level system of the present disclosure is not limited to shifting a sun-roof in a car. The disclosure can be applied to other applications such as shifting body panels of a car, shifting a windshield, or shifting a window in a manufactured home, for example. Any implementation in which a body has an opening and in which a glass plane (e.g. glass plate) is installed and shifted could be benefited by the features of the present disclosure.
Modifications to embodiments of the disclosure described in the foregoing are susceptible to being implemented without departing from the scope of the disclosure as defined by the appended claims.
