Description

ASSEMBLY AND FIXING BOLT FOR VEHICLE DOOR INSURANCE Field of the Invention The subject invention relates to the mounting bolts and vehicle insurance associated with the insurance that is fixed to the corresponding frames of a vehicle.

BACKGROUND OF THE INVENTION Vehicle insurance is often used in a variety of applications, such as to secure a door, a luggage rack, a cape or a cover. The insurances commonly have a lodging that includes the mechanisms of liberation and assurance. The housing is between the external and internal plates where each has a plurality of openings disposed therein. The internal and external plates are welded or joined to the housing in such a way that the corresponding openings are aligned. The housing is mounted to a vehicle frame by the appropriate fasteners, such as threaded bolts, which pass through the corresponding openings.

REF: 130468 Examples of the configurations of insurance assemblies are described in U.S. Patent Nos. 4,281,478; 5,172,946; 5,308,129 and 5,328,219. These designs require that the housing be cetely assembled without fasteners and then incorporated during the mounting of the lock. In addition, additional space is needed inside the housing to subsequently install the additional mounting bolts. An improved design uses the mounting bolts as pivot points for various cnents where the mounting bolts also act to hold the housing. In other words, the securing and release mechanisms disposed within the housing utilize the area where the bolts travel through the housing as pivot points. An example of this prior art design is described in U.S. Patent No. 5,000,495. A handle is provided within the housing defining the pivot point. The bolt passes through the handle and interconnects the internal and external plates. In particular, the outer plate has a threaded portion that receives the bolt. This design is advantageous because the separate bolts are not required, the space occupied by the bolts is used and the housing is supported by the bolts themselves. However, the design requires that the external plate have threaded openings to interconnect the internal and external plates to the housing. In addition, the insurance must be mounted to the vehicle by the additional mounting bolts. Therefore, this design requires additional industrial stages to develop and assemble the insurance. Another example of a prior art safety design is described in Figures 6 and 7. Again, a handle 10 is provided within a housing that can define a pivot point. The handle 10 is located at either end to secure the inner 12 and outer 14 plates to the housing. Then, a bolt 16 is partially screwed into the handle 10 to retain the bolt 16 to the latch during operation. Upon reaching the assembly line, the latch encounters a mounting frame 18 of a vehicle and the bolt 16 is directed towards the handle 10 to mount the housing as shown in Figure 7. This design is equally advantageous due to that the separate rotating bolts are not required and the space occupied by the bolts 16 is used. This design, however, requires that the handle 10 be independently press fit into the housing to hold the inner plates 12 and ^ UHIBÍ ^ ri external 14 in the housing. In addition, the mounting bolts 16 are independently mounted through the handles 10. Therefore, this design also requires additional industrial parts and stages of elaboration and assembly of insurance. In addition, this fastening configuration is designed for the rigorous transportation of a common insurance from the production environment to a vehicle assembly plant. Therefore, it is desirable to develop an insurance that incorporates an integral mounting bolt that secures the plates and the safety housing, which acts as a 'swivel point for the internal cnents of the insurance and also assures the insurance to a vehicle. In addition, the insurance must not have the deficiencies indicated above, it must conform to fewer parts and be easier to assemble and install.

BRIEF DESCRIPTION OF THE INVENTION The disadvantages of the prior art can be overcome by providing an assembly bolt assembly and lock comprising a lock housing having an internal side and an opposite external side. An internal plate is attached to the inner side and has at least one opening. An external plate similarly joins the opposite side of the inner plate and has at less an opening aligned with the opening of the inner plate. At least one mounting bolt, having the first and second end distal, extends through the openings. A head is placed on the first distal end of the pin to join the outer plate. The assembly is characterized in that the mounting bolt has an enlarged cylindrical portion extending from the head to a support that joins the internal plate to direct the outer plate relative to the internal plate. Accordingly, the subject invention includes a mounting bolt which can be a pivot point for the components of the latch, which can hold the inner and outer plates against the housing and also provide the mounting points for the latch. In other words, the bolt and object insurance assembly holds the insurance to transport and provide a securing portion to secure the insurance to a vehicle. The subject invention is also of compact design which is easily and efficiently elaborated and installed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the Figures, where similar numbers indicate corresponding or similar parts along some views, a mounting bolt and lock assembly is generally shown with the number 20 in Figure 1. The The safety mount 20 preferably has a design and configuration that define an appropriate door latch for securing a vehicle door (not shown). As it is appreciated, the subject invention can be used in various configurations to secure the covers, hoods, luggage carriers and the like. The lock assembly 20 comprises a lock housing 22 having an inner side 24 and an opposite outer side 26. As noted, the internal and external terms are preferably used to orient the target housing 22 when it is mounted to the vehicle. The housing 22 can be positioned in any appropriate orientation depending on the particular vehicle manufacturer. An inner plate 28 is attached to the inner side 24 and has at least one opening 30. Similarly, an outer plate 32 is attached to the opposite outer side 26 of the inner plate 28 and has at least one opening 34 aligned with the opening 30 of the inner plate 28. Preferably there are three openings 30 disposed within the internal plate 28 and three openings 34 disposed within the outer plate 32 aligned with the three openings 30 of the internal plate 28. As can be seen, if desired, there may be any number of openings 30, 34 within the corresponding external 32 and internal 28 plates. As stated above, the internal and external terms are fully illustrative of a preferred mounting orientation and are not intended to limit the subject application. However, the plates 28, 32 are preferably oriented in opposite directions with the corresponding openings to be aligned. The inner plate 28 is preferably an integral portion of the housing 22 defining a cavity (not numbered) disposed within the housing 22. The outer plate 32 acts as a cover for the cavity which encapsulates the housing 22. Alternatively, the internal plates 28 and 32 can be detachable from the housing 22 such that it is between the inner 28 and external 32 plates. Various fixing and releasing components (not numbered but well known in the art) are disposed within the housing cavity 22 to provide the operating characteristics of L É É É montaje montaje montaje montaje montaje montaje montaje y 20.

Algunos 20. Algunos 20.. Some of the components may include a primary ratchet, finger, spring and similar as known in the art At least one mounting bolt 36 has the first and second end distal, which extend through a pair of aligned openings 30, 34. Preferably there are three mounting bolts 36, each consisting of the first and second distal ends, with one of the bolts 36 extending through each of the three pairs of corresponding openings 30, 34. As will be discussed in more detail below, the mounting bolts 36 interconnect the inner 28 and outer 32 plates to the housing 22 to create a portable securing assembly 20. The bolts 36 can also act as turning points for the primary and secondary locks, the ratchet and the like to other components. The subject invention therefore creates a portable and compact assembly 20 which is self-sufficient. The bolts 36 also act as turning points for the primary and secondary locks the finger and other similar components. Therefore the present invention creates a portable and compact assembly 20 which is safe. Referring also to Figures 2 and 3, one of the mounting bolts 36 is shown in greater detail. Each of the mounting bolts 36 is substantially identical. Next, for illustrative purposes, only one pin 36 is shown and subsequently described.

A head 38 is disposed at the first end of the distal bolt 36 to join the outer plate 32. As best shown in Figure 3, the head 38 of the bolt 36 includes an axial cavity 40 for receiving an installation tool (not shown). ). The mounting bolt 36 has an elongated cylindrical portion 42 that extends from the head 38 to a support 44. The elongated cylindrical portion 42 has a smaller diameter than the diameter of the head 38. The cylindrical portion 42 is also of a cross section circular substantially uniform. The cylindrical portion 42 includes a first clamping section 46 disposed adjacent the head 38 to press fit the cylindrical portion 42 in the opening 34 of the outer plate 32, whereby the first distal end of the mounting pin 36 is secured to the outer plate 32. The first fastening section 46 preferably comprises a plurality of axially extending flanges 46 arranged circumferentially around the cylindrical portion 42. The flanges 46 may be of any size, width or convenient number, as suitably secured. first end distal to the external plate 32. • üdaás ^ = uí A circumferential step 48 is disposed adjacent the head 38 and has a diameter greater than the diameter of the cylindrical portion 42 with the rims 46 disposed in the circumferential step 48. As seen, the opening 34 in the plate external 32 is complementary in size with respect to the circumferential size of step 48. When pin 36 is snapped onto outer plate 32, ridges 46 create small grooves in outer plate 32 to secure pin 36 to housing 22 and prevent the rotation of the bolt 36 relative to the housing 22. The mounting bolt 36 further includes a threaded shank 50 having a smaller diameter than that of the cylindrical portion 42 and extending from the support 44 to the second distal end. The pin 50 extends through the opening 30 in the inner plate 28 and outwardly from the inner plate 28 to provide the means for mounting the lock 20 to the vehicle. Preferably, the threaded pin 50 has a design similar to a screw threaded for machine with the tip without thread. The length, diameter, thread spacing, thread size and other similar parameters of the spigot 50 can be of any convenient design to suit a particular application. A diameter of the opening 30 inside the inner plate 28 is smaller than the diameter of the opening 34 in the external plate 32 due to the relative sizes of the peg 50 and a cylindrical portion 42. A second fixing section 52 is disposed in the mounting bolt 36 adjacent to the support 44 of the elongated cylindrical portion 42 for securing the mounting bolt 36 to the internal plate 28 as discussed above. These first and second fastening sections 46, 52 work together to continuously hold the inner 28 and outer 32 plates against the housing 22, creating a portable interengaged bolt and lock assembly 20 as shown in Figure 1. The second section of fastener 52 preferably comprises a fastening flange 52 having a plurality of corrugated projections. The corrugated projections define a fastening tab in the form of a "flower petal" 52. A diameter of the projections of the fastening flange is smaller than the diameter of the cylindrical portion 42. Referring also to Figures 4 and 5, the pin 36 is further illustrated with respect to the bolt 36 disposed within the housing 22. In particular, the support 44 of the portion MÜÉ ^ cylindrical 42 is attached to the internal plate 28 to orient the outer plate 32 relative to the internal plate 28. In other words, the elongated cylindrical portion 42 defines the depth of the cavity for the housing 22. In addition, the flange Clamp 52 is spaced from the holder 44 of the cylindrical portion 42 to extend through the opening 30 in the internal plate 28. Then, the clamp flange 52 is attached to the outer side of the internal plate 28 and the support 44 engages an inner side of the inner plate 28 for interconnecting the mounting bolt 36 to the housing 22. Accordingly, the mounting bolt 36 is secured to the housing 22 by snapping into the opening 34 of the outer plate 32 and interengaging over the opening 30 of the internal plate 28. The deflection of the fastening flange 52 works with the head 38 to restrict axial movement along the mounting bolt 36. During assembly of the mounting bolt and lock 20, the threaded pin 50 passes through a corresponding opening (not numbered) in a frame 54. Preferably, the frame 54 is a door frame such that the assembly 20 is used to secure the door to the vehicle. The subject invention is not limited to mounting to door frames 54 and to any appropriate portion of the vehicle. To complete the installation, a nut 56 is screwed into the threaded shank 50 to secure the housing 22 to the frame 54. As will be clarified at this point, the subject invention provides a simplified safety installation procedure that does not require the use of separate bolts. or the insurance housing assembly 22. The invention has been described in an illustrative manner, and it will be understood that the terminology that was used was considered to be in the nature of the words of the description rather than a limitation. It is evident to those skilled in the art that various modifications and variations of the present invention are now possible in the clarity of the above. Therefore, it will be understood that within the scope of the appended claims, the invention may be practiced differently than as specifically described.

It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects or products to which it refers.
