The present invention relates to a connecting device for a windshield wiper without a support frame and a hooked windshield wiper arm, and more particularly to a special connecting device exclusively used for a frameless support wiper and a hooked wiper arm. All replacement procedures for frameless support wipers and hooked wiper arms that not only require the help of others but eliminate any interference can be completed quickly and easily by only one person.

Today, windshield wipers used in most vehicles are classified into two types: "frame support wipers" and "frameless support wipers," which are "mass support wipers" that are used for mass in all older vehicles that have been open for a long time. Has been used as a mass scale; The "frameless support wiper" has recently been applied to new vehicles as a whole to gradually replace the old "frame support wiper" due to its good frictional effect and long-term durability, as well as environmental protection to reduce the material of the support frame. It is used. In addition, most head shapes of the wiper arms that are coupled to the "frame support wiper" take the form of hooks. US Pat. Nos. 6.640.380, 6.591.445, 6.539.576, 6.332.236, 6.161.249, 5.937.474, and 5.611.103. As disclosed, in order to combine the "frame-type support wiper" with hook-type wiper arms into a unitary unit in order to obtain the expected frictional effect on the windshield, a special connector of an integral plastic extrusion body must be used.

Also, since the structure of the "frameless support wiper" is completely different from the structure of the "frame support wiper", the head shape of the wiper arm coupled to the "frame support wiper" is different from the wiper arm. do. As well as US Patent Publication Nos. 2004/0216260, 2004/0010882, 2004/0211021, 2005/0011033, 2004/0025280, 2004/0098821; U.S. Pat. Nos. 6.75.432, 6.6.799.348, 6.6.94.639, 6.974.195, 6.1010.556, 6.43.889, 6.67.68.419, As disclosed in 6.687.948, 6.682.581, 6.68.926, and 6.610.244, the exclusive connection device for each head type of the wiper arm is referred to as the "frameless support wiper". It must be designed to be combined with ". According to all these patent specifications, the exclusive connection must be applied for certain other types of wiper arms.

However, many consumers who own the old vehicle with the "framed support wiper" and want to replace it with "frameless support wipers" do not get what they want because the "frameless support wiper" This is because their vehicles do not have adequately exclusive connectors for traditional hooked wiper arms to join, and consumers who insist on replacing it with a "frameless support wiper" should discard the existing hooked wiper arm, At the expense of replacing the exclusive head form of the wiper arm suitable for the "frameless support wiper", some factories not only relieve the economic burden on the consumer, but also remedy the disadvantages described above. Special frameless combination of frameless support wipers with conventional hook type wiper arms 1 to 7 and 16, the structure of this connecting device comprises a base 20, a frame hood 30, a pivotable cover 40 and a connector 50. The base 20 formed by pressing a hard metal includes a pair of horizontal clipping grooves 21, which grooves face each other in the longitudinal direction, and are arranged in parallel and spaced apart from the bottom of both panels. A pair of vertical left panel 23 and right panel 24, which are symmetrical, parallel and identical in shape to each other, stands up on both edges of the upper surface 22 connected with the two clipping grooves 21. Also, the horizontal The transversal fixation spindle 25 is transversely spanned to the left panel 23 and the right panel 24. By the clipping groove 21, the base 20 of the frameless support wiper 10 It can be fixedly clipped onto the elastic metal strip 11. The frame hood 30, which is an integrally extruded body made of plastic material, comprises a pair of vertical left hood panels 31 and right hood panels 32; the left and right hood panels are parallel to each other and are identical. It is shaped and upright on both sides. For the left and right hood panels 31, 32, the horizontal crosslinking spindle 33 is transversely over its front end; The vertical coupling plate 34 stands up at its rear end; A pair of left insertion grooves and right insertion grooves 36, which are symmetrical and parallel to each other, are formed spaced inwardly from the middle portion thereof; The left insertion groove and the right insertion groove are opened to face downward and have the same shape. A pair of left baffle lumps 37 and right baffle lumps 38 are provided on the inner side at the upper edges of the left insertion groove 35 and the right insertion groove 36. In addition, the two pairs of snap coupling nose portions 39 correspond to the opening directions of the left insertion groove 35 and the right insertion groove 36, and the bottom of the left hood panel 31 and the right hood panel 32. It is installed on the inside at the edge. The base 20 having the left panel 23 and the right panel 24 is frame hooded by the left insertion grooves 35 and the right insertion grooves 36 as well as the four snap engagement noses 39. It is fixedly inserted inside the 30 (as shown in FIG. 16). The pivotable cover 40 freely pivoted onto the cover on the frame hood 30 has a tubular groove 41 disposed on one short end and a pair of elastic uprights on the left and right panels on the other short end. And snap ring 42. By engaging the tubular groove 41 and the engaging spindle 33 on a frame hood 30, the pivotable cover 40 is provided with the engaging spindle (as shown in FIGS. 6A and 6B). In the frame hood 30 having the back 33, it is lifted up and down over the top surface of the front part. Connector 50, which is an integrally extruded body made of plastic material, similar to the conventional connector of the "frame support wiper" to be inserted between the left panel 23 and the right panel 24 of the base 20. Comprises a pair of left and right plates 51 and symmetrical, parallel and identical in shape, the left and right plates being horizontal body plates 53 which span over them to form an integral body. The branches are erected spaced apart on both sides thereof. The pair of tightening noses 54 are arranged side by side inside the front ends of the left and right plates 51 and 52 to form a space for receiving the hook head 61 of the hooked wiper arm 60. Spaced apart. In addition, horizontally disposed in the middle portion of the left side plate 51 and the right side plate 52 to be coupled to the fixed spindle 25 so that it can be pivoted at a defined angle inside the base 20 itself. The body plate 53 is formed with a round groove 55 facing downward.

6 to 9 show the mounting assembly operation of the connecting device used in the traditional hook type wiper arm 60. First, one finger is placed on the pivotable cover 40 to deform two elastic snap engagement rings 42 to release clipping from the left insertion groove 35 and the right insertion groove 36 (shown in FIG. 6B). To exert strength. By means of the engaging spindle 33 which is the lever support means, the pivotable cover 40 can be lifted freely from the frame hood 30 (shown in Fig. 7D). Subsequently, the hook head 61 of the hook-type wiper arm 60 is inserted between the left side plate 51 and the right side plate 52 of the connector 50; The force is continuously applied until it is fully seated in the space between the front edge of the horizontal body plate 53 and the two tightening noses 54 to complete the fastening (Fig. 7E, as well as Fig. 7E). 8 and shown in FIG. 9). Finally, the pivotable cover 40 is pivoted again to snap onto the top surface of the frame hood 30, thereby completing the mounting assembly operation.

Conventional linking devices as described above can achieve the purpose of coupling a "frameless support wiper" to the traditional hook head of a hooked wiper arm, but there are several drawbacks as follows.

1. In Figs. 10-12, during the operation of the frameless support wiper 10, the conventional connecting device is always interrupted by the pivotable cover 40, so that it is not smooth. This is because the hooked wiper arm 60 must be in an upright position each time the frameless support wiper 10 is replaced. That is, in order to be erected by the elastic collapsible segmentation means 62 of the lever support to separate the frameless support wiper 10 away from the windshield G during the replacement operation (shown in FIG. 11), An upward force (shown in FIG. 10) is applied horizontally on the hooked wiper arm 60 on the windshield G. Thus, the frame hood 30 is always in an upright state regardless of the mounting operation or detachment operation; The engaging spindle 33 in the top position can freely pivot the pivotable cover 40 downwards and interferes with the hook head 61 (shown in phantom in FIG. 12H). Thus, during the detaching operation or the mounting operation, the hook head 61 collides to damage the pivotable cover (shown in Fig. 12I), which makes the work cumbersome. In order to avoid such a phenomenon as described above, a cumbersome helper for temporarily supporting the pivotable cover is needed (shown in Fig. 12J). This is a hindrance to the designer's intentions.

2. In Figures 9, 10A, 13, and 14, when the hooked wiper arm 60 pivots back and forth on the windshield G, the final force F will be generated. The hook head 61 will continually strike and press against the two tightening noses 54 on the connector 50 under the action of the vertical component force F1 (shown in FIG. 10A). Finally, the hook head 61 will destroy the connector 5 after a time period of setting or the number of turns of setting of the hook-type wiper arm 60 (this operation is shown in Figs. 9A to 9D). ). The reason is that the two left hood panel 31 and the right hood panel 32 (to accommodate the displacement of the two deformed tightening nose portions 54 by the impact and the press from the hook head 61). This is because there is a gap δ between the two left plates 51 and the right plate 52 having the one shown in FIG. Destruction of the hook head 61 from the connector 50 is a difficulty hidden during safe driving of the vehicle. This is another major drawback beyond the original designer's safety considerations.

3. In FIGS. 3 and 15-17, each of the engaging spindle 33 and engaging plate 34 is adapted to facilitate lifting and lowering of the pivotable cover 40 itself. Are arranged before and after respectively. A round cross section with a small area of the engaging spindle 33 and a square cross section with a large area of the engaging plate 34 cause them to have different stress strengths (shown in FIG. 3). The two snap engagement nose portions 39 on the left hood panel 31 and the right hood panel 32 are exposed to impact forces and pressing forces from the left panel 23 and the right panel 24 (shown in Fig. 16E). ), It expands in the outward direction (shown in Fig. 16F). On the other hand, the coupling spindle 33 and the coupling plate 34 withstand the same axial stress f from the left hood panel 31 and the right hood panel 32 due to outward expansion pressure in the middle. will be. Thus, one end of the coupling spindle having a small cross-sectional area will be destroyed from the left hood panel 31 and the right hood panel 32 (shown in FIG. 17), thereby damaging the frame hood 30. FIG. The above situation always occurs during the mounting process, so the yield is low. This is another major drawback beyond the original designer's intentions.

It is a primary object of the present invention to provide a connection device for a windshield that does not have a support frame and hook-type windshield wiper arms and includes a chassis and saddle hood, a sliding cover and a connector. By tightening the two insertion projections on the sliding rail with two insertion holes on the left panel and the right panel of the chassis, the sliding cover can quickly slide the saddle hood in a tightening fixing position that cannot be separated from each other. Therefore, the connector does not need the help of others to support the sliding cover during the detachment and mounting of the hook head on the hook-type wiper arm, and also eliminates the interference of impact caused by the sliding back of the sliding cover. Only one person can complete the process quickly and easily.

The left hood panel and the right hood panel on the saddle hood are spanned and joined by a horizontal straddle panel and a vertical rear hood panel of the same rectangular cross-sectional area having an equivalent area. Inserting the Saddle Hood into the Chassis The straddle panel and the rear hood panel are equivalent due to the four snap-in nose portions on the left hood panel and the right hood panel that are impacted and pressed by the left and right panels on the chassis during the mounting process. Due to its same rectangular cross-sectional area with an area of s it can be evenly exposed to axial stress. Accordingly, breakage damage of the straddle panel and the rear hood panel of the left hood panel and the right hood panel does not occur.

27, 28, 30, 34, and 40, which illustrate the replacement of the frameless support wiper 10, the windshield in a horizontal manner, similar to the conventional windshield wiper described in the replacement process of the wiper. A upward force is applied to the hook-type wiper arm 60 pressed against (G) (shown in FIG. 34), and the spherical shape of the spherical glass wiper 10 can be removed from the windshield so as to start removing and replacing the frameless wiper 10. FIG. It is lifted to an upright position by elastic, collapsible segmentation means 62 as a lever restraining " frameless support wiper " (Fig. 35). Therefore, the saddle hood 80 is always in the upright position regardless of the detaching operation and the mounting operation. The steps of removal or installation are very easy as follows. First, the sliding cover 90 is held above the saddle hood 80 so that the insertion projections 951 cannot be dropped downwards by tightening the insertion protrusions 951 to each other in the snap engagement grooves 78, so that the snap engagement grooves are accompanied by a snap engagement sound. The sliding cover 90 is pulled from the saddle hood 80 to the two insertion protrusions 951 on the sliding rail 95 fastened to 78 (shown in Figs. 27, 28 and 36M). In the meantime, due to the pressurized tongue 97 on the sliding cover 90 which releases the tightening of the left side plate 101 and the right side plate 102, the left side plate 101 and the chassis having the right side plate 102 are formed. A gap δ is formed between the front panel 75 on 70 (shown in FIG. 38). Thus, the hook head 61 can be stably inserted into the connector 100 without interference (shown in FIGS. 36N as well as FIGS. 39 and 40, respectively). Finally, the sliding cover 90 is pressed against the saddle hood 80 up to the resilient fastening hook 96 which is tightened with the snap engagement groove 78 on the chassis 70 with the snapping sound. (Shown in FIGS. 30 and 36O). In the meantime, in order to block the two tightening noses 104 on the front end of the connector 100 from the outward displacement (shown in FIG. 37), the hook-type wiper arm 60 is also turned during the swing operation. In order to ensure a state that cannot be separated from the connector 100, the pressurized tongue 97 on the sliding cover 90 is provided with a left side plate 101 having a right side plate 102 and a front panel on the chassis 70. Rebound to fill the gap δ between 75.

In Fig. 41, during the disassembly and mounting of the replacement operation, all replacement processing can be easily and quickly completed by only one person without any help from others. In addition, inadvertent fall of the conventional pivotable cover 40 not only prevents collision interference with the hook head 61, but also damage to other parts.

21 and 42, the straddle panel 84 and the rear hood panel 83 are left hood panel 81 during the insertion mounting process of the saddle hood 80 into the chassis 70 in the present invention. And axial stress f caused by the displacement to the outside of the right hood panel 82 (shown in FIG. 42). This axial stress f is uniformly distributed in the straddle panel 84 and the rear hood panel 83 because of the same rectangular cross-sectional area with an equivalent area. Therefore, breakage damage which has occurred in the conventional connecting device due to non-uniform stress and unequal area can be avoided.

The present invention enables fast sliding away from the saddle hood tightened to a fixed position whereby the sliding cover cannot be separated from each other by tightening the two insertion projections on the sliding rail to the two insertion holes on the left panel and the right panel of the chassis. . Therefore, during the detachment and mounting of the hook head on the hook-type wiper arm with the connector, not only need any help from others to support the sliding cover, but also the impact interference caused by the sliding back of the sliding cover. It can be removed and all processes can be completed quickly and easily with just one person.
