MOLDING CLIP
This invention relates to a clip for l~obilizing a decorative molding to be attached along the edge of the plate of glass in the front or rear window of an automobile.
In setting a plate of glass in the front or rear window of an automobile, it is a widely known practice to fasten a molding along the edge of the window for the purpose of filing up the gap occurring between the edge of the window frame and that of the plate of glass or imparting a decorative effect to the bondary.
The fastening of the molding has heretofore been accom-plished generally by a method which comprises embedding T-shaped studs at suitable intervals along the edge of the window, fastening the plate of glass to the edge by use of an adhesive agent, attaching a clip made of synthetic resin to each of said studs and bringing the molding into fast engage-ment with the clips. Another method heretofore used for this purpose comprises causing clips made of resilient metal plate material to be attached in advance to the edge of the plate of glass, setting the plate of glass in position in the window opening so as cause the plate of glass to be immovably joined to the edge of the window in conjunction with said clips by the medium of an adhesive agent applied in advance to said edge of the window and thereafter bringing a molding into fast engagement with the clips.
The former method necessitates preparatory individual welding of the T-shaped studs adapted to permit attachment of clips and furthermore involves the subsequent extra work of attaching the clips to the welded studs and, hence, the operation ',~
1065~Z4 as a whole proves to be inefficient and costly. The latter method immobilizes the clips not by relying upon studs pre-paratorily imbedded into the window frame but by utilizing an adhesive agent primarily intended for fastening the plate of glass to the window frame. Use of this method, therefore, advanced training in the work of applying the adhesive agent and the work of setting the plate of glass having clips attached thereto in position in the window frame and is hardly appropriate for adoption in an assembly line. Because of the use of clips made of a metal, this method has an additional disadvantage that the clips tend to rust and, at the time of assembly, are likely to cause scratches in the paint finish of the automobile.
An object of the present invention is to provide a molding clip which is outstandingly adaptable to use in mass production assembly in that it is not likely to mar the paint finish of the window frame, in that it is totally safe from rusting, in that it permits easy selection of the position for its attachment and in that it can be attached simulta-neously with the plate of glass to the window frame;.
Another object of the present invention is to provide amolding clip which insures easy attachment of the molding, precludes the possibility of the clip being pushed out of - position by the attachment of the molding and permits later release of the molding from engagement with the clip if such should become necessary.
Still another object of this invention is to provide a molding clip which can be integrally molded easily and in-expensively by the techni~ue of injection molding of a plastic ~06S9Z4 material and which can easily be adapted to the existing process of molding attachment.
The invention in its broader claimed aspect comprehends a one-piece plastic molding clip which includes a generally planar base plate adapted to be attached on its back side by adhesive means to a window opening flange in an automobile. At least one engaging arm is attached at one end to a lower edge of the base plate and extends substantially parallel to and in spaced relation to the plane of a central portion of the base plate, the at least one engaging arm being provided at the free end thereof with a molding engaglng snap catch. At least one resilient receiving member is disposed in spaced relation to a front side of the base plate and connecting means permit it to extend from adjacent an upper edge of the base plate opposite the lower edge downwardly in spaced relation to the front side of the base plate in the direction of the lower edge and is adapted to resiliently receive an edge of a plate of glass.
With this molding clip, required attachment of a decorative and plate glass-immobilizing molding possessed of a flap portion is accomplished by joining the rear surface of said base plate through the medium of a two-face adhesive tape to the edge of the window frame, allowing the edge of the plate of glass to be set in the window frame to be supported by said resilient receiving members, setting the plate of glass in position in the window frame and thereafter bringing the molding into hooked engagement with a molding-engaging piece. This molding clip enables the plate of glass to be easily and safely attached immovably to the window frame by causing the plate of glass to be supported on one side of the edge thereof by the clip fastened to the window frame and on the other side of the edge thereof by the molding fastened to the molding-engaging nail catch. Since the clip is fastened to the window frame by means of an adhesive tape, the - positioning of the clip can easily be attained without inflicting injuries to the paint finish of the window frame. Release of B the clip from ~0659Z4 engagement with the molding can be carried out easily if it should become necessary to replace the plate of glass.
Because of the simplicity of its structure, the molding clip of the present invention can easily be integrally molded by the conventional technique of injection molding of a plastic material and can readily be adapted to the existing process for the engagement of the plate of glass and the molding.
The other objects and characteristic features of this invention will become apparent from the detailed description to be given hereinbelow with reference to the accompanying drawings.

Figure 1 illustrates a typical example of the conventio-nal molding clip, representing a partially enlarged view of awindow frame F used in an automobile for attachment of a wind-shield or a rear window.
A plate of glass G for the window is immobilized by being supported on one side by a molding M held in position by a molding clip 1 and on the other side by the edge portion of the window frame F through the medium of a packing material such as an adhesive agent.
With the conventional molding clips of such a construc-tion, studs S must be fixed by welding or some other means at prescribed positions along the window frame to permit fasten-ing of the clips to the window frame F.
The conventional molding clips are each provided at the lower central portion with an Q-shaped fitting hole 2 for receiving the head of a stud S and at the upper portion with a molding engaging nail catch 3 for permitting hooked engage-ment of the hooked portion of the molding.
With these conventional molding clips, required setting of the plate of glass is accomplished by fastening said molding clips to the window frame F while allowing the head 10~59Z4 portions of studs S to be inserted into the fitting holes 2, applying a packing material such as adhesive agent to the end portion of the window frame F, thereafter inserting the plate of glass in position into the window frame and, after the plate of glass has been get in position as described above, forcing a springy metallic molding between the window frame F
and the molding clip with the hooked portion at the leading end and bringing the hooked portion into hooked engagement ~ with the molding engaging nail catch so as to obstruct re-lease of the molding.
Since the conventional molding clips necessitate pre-paratory embedding of studs as described above, the fabrication of the window frame inevitably entails the extra work of complicated welding and the insertion of the molding may scratch paint finish of the window frame. Removal of the plate of glass fastened in position or the molding held in hooked engagement may be accomplished by breaking the molding or molding clips or by strongly pushing up the plate of glass from below (in the position of the drawing) with force enough to upset the inserted engagement between the studs S and the fitting holes 2 of the molding clips. In either case, the removal is not obtained readily.
The conventional molding clips of the construction of Figure 1 have a serious disadvantage in terms of both ease of handling and cost.
Conventional molding clips of another structure illust-rated in Figure 2 are formed each by fabricating one metal sheet in the shape o~ the letter U as shown in Figure 2(B).
As many molding clips 4 as necessary are clamped astraddle the edge portion of the plate of glass G in advance. To the peripheral edge of the window frame F, a packing material P
of adhesive agent or the like is applied in advance. As the plate of glass is fastened to the window frame F, the tongues 5 of the molding clips are allowed to be embedded into the packing material P. When the plate of glass is set in posi-tion onto the window frame F by means of the adhesive packing material P, it is ready for attachment of a molding M to the periphery thereof. This attachment of the molding is accom-plished by bringing one of the bent portions formed at theopposite ends of the molding into hooked engagement with the engaging member 6 formed by cutting and raising a portion of the molding clip in the shape of an S and bringing the other bent portion into hooked engagement with the engaging member 7 formed by bending the end portion of the molding clip. As the plate of glass G is held fast in position by the molding clips, it is resiliently held at its end portion by glass receiving pieces 8, 8.
With the conventional molding clips,of the foregoing construction, the setting of the plate of glass and the molding is effected by a method which comprises fastening the clips preparatorily to the edge of the plate of glass and fastening the plate of glass in conjunction with the molding clips onto the edge of the window frame by use of an adhesive agent applied in advance to said edge. Unexpectedly, this applica-tion of the adhesive agent requires an adva~ced technical skill on the part of the worker. In fact, the required degree of skill is so great that the method as a whole is hardly usable in an assembly line, thus depriving the method of its technical feasibility.
The conventional molding clips of the construction under discussion are produced by fabricating resilient metal sheet to shape. They, therefore, have a disadvantage that the clips eventually rust and thiS rust transfers to the automobile body and the plate of glass surface. The clips are also likely to scratch the paint finish of the automobile body if they should accidentally collide with the painted surface during the work of window assembly. Such scratches can eventually cause corrosion of the substratal metal through the marred surface.
Besides, possible variation in the size of the plates of glass and variation in window size cause a variation in the retain-ing strength of clips and, on account of close association with the rigidity of the molding in use, a gap is likely to occur between the automobile body and the molding, with the undesirably result that the molding suffers from impaired appearance and degraded quality.
In view of the various disadvantages suffered by the typical molding clips heretofore available as described above, the present invention aims to provide molding clips free from these disadvantage. Now, the present invention will be described with reference to the preferred embodiments illust-rated in Figure 3 and the subsequent figures.
A clip 11 is formed having as its main component parts a base plate 12 adapted to be laid in face-to-face contact on the wall rising from the window frame F, a springy engaging piece 13 vertically rising from the lower edge of said base ; plate and provided at the free end thereof with a backwardly projecting nail catch 15 for hooked engagement with the molding ~6592~
and resilient receiving members 14, 14 protruding from the upper edge of the base plate to the front side of the base plate (Figures 3 and 4~. Said base plate 12 functions as a base seat immobilized to the edge of a window frame and is provided with a base piece 16 protruding from the lower edge thereof perpendicularly to the front side. The clip is brought into stable engagement for snug rest at the corner portion of the edge of the window by causing the rear side of the base plate and the lower side of the base piece 16 to come into perfect contact with the two inner sides of the corner portion.
The engaging piece 13 serves to retain the molding in hooked engagement by bringing the hooked edge of the molding M into engagement with the molding-engaging nail catch 15 formed at the free end thereof. In the illustrated embodi-ment, this engaging piece 13 is formed in a rising state as if cut off and raised from the central portion of the base plate 12. The main body of the engaging piece 13 is so formed as to stand substantially past the front face of the base plate and the molding-engaging nail catch formed at the free end of said engaging piece is extended so much that the leading end thereof protrudes beyond the rear face of the base plate. The rear side of the engagillg piece 13 immedi-ately below the molding-engaging nail catch 15 is notched to form an indentation 17 and the opposite side of the engaging piece 13 from said indentation is extended to give rise to an ear piece 18 adapted to permit hooked engagement of a tool which is used for releasing the molding from its engagement with the nail catch. The resilient receiving members 14, 14 ., serve the dual purpose of receiving the edge of plate of glass G being set in the window frame and, by virtue of the pressure generated by said reception of the plate of glass, pressing said base plate against the edge of the window frame. In the preferred embodiment under discussion, they are extended from the upper edge of the base plate in a down-folded state and the extended portions are downwardly inclined toward the front so as to thrust out of the front side of the base plate, with their leading ends sharply bent up to form receiving portions 19, 19. In the preferred embodiment illustrated here, the resilient receiving members are disposed one on each side of said engaging piece 13 in a symmetrical relationship relative to said engaging piece 13. Owing to the overall arm length including the folded portion, these receiving members manifest resilience, so that the edge of the plate of glass may be snugly received by the receiving portions 19, 19 formed at the forward ends thereof. The front sides of said resilient receiving members are twisted sideways so that the inner edges of the front sides protrude in the form of ridges. When the plate of glass G is set in position as described afterward, these protruding ridges serve the purpose of preventing the edge of the plate of glass from scraping off the adhesive packing material P applied to the lower face of the plate of glass.
Thin-walled tongue pieces 20 formed on the rear side of the base plate and extending beyond the upper edge of the base plate are provided one on either side of the free end of the engaging piece. When the molding M is brought into engagement with the nail catch 15, the tongue pieces 20 are caused to i5924 come into contact with the outer side of the hooked edge of the molding M, thus serving to prevent the molding from coming into direct contact with the edge of the window frame.
Subsequently, in the clip of the construction described above, a two-face adhe~ive tape 21 is attached (or an adhesive agent may be appliedl to the rear side of the base plate 12 and the clip is pressed and fastened immovably against the rising wall of the window frame through the medium of said tape. In this case, the base plate is pressed against the rising wall only after the clip has been positionally stabi-lized by causing the base piece 16 formed at the lower edge of the base plate to fall snugly into perfect rest at the corner of the window frame. After a plurality of clips have been adhesively fastened at suitable intervals to the edge of window frame as described above, the plate of glass G having an adhesive packing material P applied in a required thickness to the lower face of its edge is poised over the array of clips and the edge of the plate of glass is slid on the front sides of the resilient receiving members 14, 14 and driven backwardly until it comes into tight contact with the receiving portions 19, 19 at the leading ends thereof while causing the pressure exerted by the edge of the plate of glass in motion to spread out the excessively applied adhesive packing material.
Consequently, the adhesive packing material buries the lower portion of the base plate 12 and the forward ends of the resilient receiving members 14, 14 and, after it is left to set, solidifies to immobilize them collectively. In this case, the possibility of the adhesive packing material P applied to the edge of the plate of glass being spread out under said pressure toward the interior portion of the plate of glass may effectively be precluded by providing the lower surface of the plate of glass with a rubber seal 22 in advance.
After the clips have been fastened to the window frame F in consequence of the adhesion of the edge of the glass of plate, the molding M is brought down to cover the clips and the hooked edge at one end of the molding is wedged in between the tongue pieces 20, 20 and the leading ends of engaging pieces 13 (Figure 4~, with the result that the wedging makes the molding-engaging pieces 15 bend forward and causes the hooked portion thereof to be brought into hooked engagement with the molding-engaging nail catch. The attachment of the molding is thus brought to completion (Figure 5). In this case, the molding M is pressed down in the direction of ex-panding the hooked edges at the opposite ends thereof so asto generate a repulsive force in the molding itself. After the molding is fastened to said molding-engaging nail catch 15, said repulsive force presses the remaining free folded edge against the front surface of plate of glass and prevents any gap from occurring between the plate of glass and the molding.
Since the molding is fastened in position as described above, the clips tend to be lifted forward or upward by the repulsive force of the molding and consequently pull in the pealing direction the base plate 12 which has already been immovably fastened to the edge of window frame through the medium of sald adhesive tape. Nevertheless, the attachment of the molding does not cause the clips to be pushed up and the prying force exerted by the molding upon the engaging 1~659Z4 piece does not peel the adhesive tape because the engaging piece serving to keep the molding directly in hooked engage-ment is connected to the lower edge of the base plate and consequently transmits the resilient force of the molding indirectly to the base plate as previously described, because said resilient receiving members 14, 14 support the edge of the plate of glass and, under the load of the plate of glass, press said base plate against the rising wall of the edge of the window frame and further because the receiving portions l9, 19 formed at the forward ends thereof are held in firm contact with the lower side of the plate of glass to offset the upward pull.
With the molding clips produced according to the present invention, therefore, even when the molding is attached before the adhesive packing material P has thoroughly solidi-fied, the clips will not come off their attached positions on the window frame F but will maintain the molding in hooked engagement therewith. Thus, the attachment of the molding can be started before the adhesive packing material has been completely solidified. This means that the work of molding attachment can be carried out very ~uickly. And the molding thus atta'ched in position to the window frame will not suffer from such undesirable phenomena as partial peeling but will insure safe fastening of the plate of glass.
The receiving portions 19, 19 of the resilient receiving members are held in fast contact with the lower side of the plate of glass and prevent the clips from lifting up. In the present preferred embodiment, they intervene between the glass and the window frame F and give rise to a fixed gap for retaining the adhesive packing material therebetween. Because of this fixed gap, a required amount of adhesive packing material remains intact in the gap in spite of the pressure which is produced when the plate of glass is mechanically inserted in position.' The adhesive packing material thus retained in the gap serves to effect adhesive attachment of the plate of glass and seals airtightly the gap between the plate of glass and the edge of the window frame.
Figure 7(A) and Figure 7(B) represent another preferred embodiment involving a partial modification with respect to the resilient receiving members 14, 14 and the base piece 16 of the preferred embodiment described above. This modification resides in omitting the formation of the receiving portions at the forward ends of said resilient receiving members and instead enlarging the base piece 16 for thereb,v forming on the upper side thereof a pillow 23 for supporting the lowe,r side of the plate of glass.
In this preferred embodiment, the base piece serves to stabilize the attachment of the base plate 12 as described previously and the pillow 23 formed on the upper side thereof supports the lower side of the plate of glass and prevents the plate of glass from sinking further down and insures undis-turbed retention of the adhesive packing material. At the same time the base piece becomes buried itself under the pool of adhesive packing material and consequently immobilizes the clip as a whole. When the molding is attached to the clip, the base piece which is held in tight contact with the lower side of plate of glass prev'ents the clip from lifting up and also serves the purpose of preventing the adhesive tape from ~065929~
peeling off. The preceding preferred embodiment requires the adhesive tape to be applied to the rear side of the base plate. Owing to the enlargement of the area of the base piece, the present preferred embodiment can immobilize the clip by means of an adhesive tape applied to the lower side of the base piece.
Figure 8 through Figure 10, incl. represent modifications to the preferred embodiments described above. The preferred embodiment of Figure 8 has engaging pieces disposed one on either side of the base plate 12, that of Figure 9 has resili-ent receiving members 14, 14 extending between the upper edge of the base plate 12 and the receiving piece 16 with their respective opposite ends integrally connected to the upper edge of the base plate 12 and the receiving piece 16 and that of Figure 10 has resilient receiving members 14, 14 of the preferred embodiment of Figure 9 cut off at the upper ends thereof from the upper edge of the base plate and supported exclusively by the receiving piece. All these pxeferred embodiments produce identical effects to those obtainable by the preferred embodiments illustrated in Figure 3 through Figure 6, Figure 7(A) and Figure 7(B).
To enhance the safety o~ the attachment of the molding and the plate of glass, the present invention also provides a molding clip of a construction that will now be described.
By way of example, there will first be considered a case in which the molding clip of this invention illustrated in Figure 3 breaks loose from engagement owing to inferior workmanship during the attachment of the molding and the plate of glass. This problem will be discussed with reference o~
10659Z~
to Figure ll.
In the initial stage of the insertion of plate of glass, when the edge of plate of glass comes into sliding contact with the resilient receiving members l9 and forces the resi-lient receiving members to bend in the direction of the frontsurface of the base plate 12, the resilient receiving members are subject to the downward force exerted by the edge of the plate of glass. Since this downward force functions as a counterclockwise moment in the entire clip, the upper portion of the base plate tends to depart from the window frame F, the lower portion thereof tends to press the adhesive tape toward the interior and the clip ll tends to incline down wardly in the front direction and break loose from the window frame. Since the work of wedging the molding in between the engaging piece 15 and the tongue piece is carried out before the adhesive packing material P applied to the edge of the plate of glass has been thoroughly solidified and since the hooked edge of the molding M repulses the engaging piece 15 toward the front side, a force is additionally exerted to remove the clip from the aforementioned state. Consequently, the adhesive tape is peeled off the clip's base plate or the window frame and the clip may possibly break loose. This trend is particularly conspicuous when the substrate of the adhesive tape is made of a material deficient in resilience.
This is because the inclination of the base plate increases and the distance between the upper edge of the base plate and the edge of window frame consequently increases in propor-tion as the amount of deformation of the adhesive tape increases, - ~06S924 For this reason, the preferred embodiments of the present invention to be described hereinbelow each have provided at the lower portion of the rear side of base plate with a protrusion having a height equal to or slightly smaller than the thickness of the tape 21 being used. When the aforemen-tioned force develops and tends to exert its impact, said protrusion stops itself against the edge of the window frame, bears-the force and prevents the clip from inclining down-wardly toward the front side and breaking loose from the engagement.
Figure 12 illustrates a preferred embodiment in which protrusions 24, 24 having a height slightly smaller than the thickness of the adhesive tape 21 are formed along the lower edge and upper edge of the rear side of the base plate 12 and the adhesive tape 21 is applied to the rear side of the base plate between the two protrusions. In this case, in the initial stage of the insertion of plate of glass, namely while the resilient receiving members 14 have not yet been bent by the edge of the plate of glass in the direction of the base plate 12, the force exerted by the edge o~ the plate of glass is received by the upper edge of the base plate at which the resilient receiving members are attached to the base plate. As a result, the upper edge of the base plate is moved in the direction of the window frame. The protrusion 24 formed along the upper edge serves to prevent such move-ment of the upper edge of the base plate. The protrusion 24 formed along the upper edge, however, fails to fulfil the purpose of bearing the force exerted during the insertion of the molding and, for that reason, may be omitted. The protru-.' ~0659Z4 sions are not always required to be formed continuously as illustrated but may instead be formed in segments, for example, in two segments falling one on each end or in three segments of which two fall one on each end and the remaining one falls at the center; Presence of the protrusion 24 prevents the adhesive tape from exposure.
If these protrusions are formed on the rear side of the base plate in the portions which have heretofore been used for application of the adhesive tape 21, then the area availa-ble for application of the adhesive tape is decreased by the area occupied by the protrusions and the strength of attach-ment to the window frame is proportionally decreased. Such undesirable decrease may be eliminated by increasing the area of the base plate enough to provide the same area for appli-cation of the adhesive tape. If the size of the window opening in the direction of depth, namely the size of the base plate in the vertical direction, is limited, then the problem may be solved by forming extended portions 25 one each at the opposite ends of the base plate as illustrated in Figure 14 or Figure 15 and further forming protrusions 24 each at the lower ends of the rear sides of said extended portions 25.
According to the molding clips of the present invention, in the initial stage of the insertion of the plate of glass, when the edge of the plate of glass pushes and bends the resilient receiving members 14 in the direction of the front side of the base plate, the moment exerted on the base plate of the clip tends to cause the lower portion of the base plate to press the adhesive tape and make the base plate incline downwardly toward the front side. However, the protrusions 24 bear this force and keep the adhesive tape from being pressed down, so that the base plate hardly in-clines (Figure 13). Thus, the possibility of the base plate breaking loose from the attachment with the edge of the window frame is completely eliminated. Similarly, the force which tends to pry the base plate out of the window frame during the insertion of the edge of molding into the engaging piece is supported by the protrusions 24. Thus, the possi-bility of the clip breaking loose from the engagement byvirtue of this force is perfectly prevented.
The illustrated preferred embodiments of this invention have been dçscribed. The clips of the present invention are temporarily fastened individually to the edge of the window frame by means of an adhesive tape or adhesive agent and `thereafter are collectively immobilized by utilizing the ad-hesive agent being used for adhesive engagement of the plate of glass. The attachment of the plate of glass and the mold-ing by use of the clips of this invention, therefore, can be effected quite efficiently as compared with the conventional method which involves preparatory attachment of studs for footing, for example, and without the possibility of rusting.
Furthermore, the engaging piece intended to permit hooked engagement of the molding is extended from the lower edge of the base plate as described above and the engaging piece itself is vested with ample resilience and is permitted to function substantially independently. Consequently, if the molding is brought into hooked engagement before the adhesive agent has been thoroughly solidified, the resilient force of the molding will neither cause the adhesive tape to come off or move out of position nor make the molding break off from the fast engagement. Thus, the clips of this invention have an advantage that the work of attachment can be performed quickly.
Further, since the aforementioned engaging piece is formed so as to enjoy freedom of deformation, desired re-placement of the molding alone can be obtained by forcibly lifting the edge of the molding held in pressed contact with the front side of plate of glass by a suitable tool, insert-ing through the opening a prier or some other tool having a hook at its leading end, hooking the prier on the ear portion or recess formed in the engaging piece, pulling the prier to bend the engaging piece toward the front side and thereby breaking the engagement of the molding with the engaging piece. In this case, the removal of the molding by the procedure described above can be accomplished without in-flicting any damage on the clip. Thus, the clips can be used again. Reusability of clips proves highly advantageous for the purpose of replacement of the molding or of adjustment to be required during the attachment of molding.
MOLDING CLIP
This invention relates to a clip for l~obilizing a decorative molding to be attached along the edge of the plate of glass in the front or rear window of an automobile.
In setting a plate of glass in the front or rear window of an automobile, it is a widely known practice to fasten a molding along the edge of the window for the purpose of filing up the gap occurring between the edge of the window frame and that of the plate of glass or imparting a decorative effect to the bondary.
The fastening of the molding has heretofore been accom-plished generally by a method which comprises embedding T-shaped studs at suitable intervals along the edge of the window, fastening the plate of glass to the edge by use of an adhesive agent, attaching a clip made of synthetic resin to each of said studs and bringing the molding into fast engage-ment with the clips. Another method heretofore used for this purpose comprises causing clips made of resilient metal plate material to be attached in advance to the edge of the plate of glass, setting the plate of glass in position in the window opening so as cause the plate of glass to be immovably joined to the edge of the window in conjunction with said clips by the medium of an adhesive agent applied in advance to said edge of the window and thereafter bringing a molding into fast engagement with the clips.
The former method necessitates preparatory individual welding of the T-shaped studs adapted to permit attachment of clips and furthermore involves the subsequent extra work of attaching the clips to the welded studs and, hence, the operation ',~
1065~Z4 as a whole proves to be inefficient and costly. The latter method immobilizes the clips not by relying upon studs pre-paratorily imbedded into the window frame but by utilizing an adhesive agent primarily intended for fastening the plate of glass to the window frame. Use of this method, therefore, advanced training in the work of applying the adhesive agent and the work of setting the plate of glass having clips attached thereto in position in the window frame and is hardly appropriate for adoption in an assembly line. Because of the use of clips made of a metal, this method has an additional disadvantage that the clips tend to rust and, at the time of assembly, are likely to cause scratches in the paint finish of the automobile.
An object of the present invention is to provide a molding clip which is outstandingly adaptable to use in mass production assembly in that it is not likely to mar the paint finish of the window frame, in that it is totally safe from rusting, in that it permits easy selection of the position for its attachment and in that it can be attached simulta-neously with the plate of glass to the window frame;.
Another object of the present invention is to provide amolding clip which insures easy attachment of the molding, precludes the possibility of the clip being pushed out of - position by the attachment of the molding and permits later release of the molding from engagement with the clip if such should become necessary.
Still another object of this invention is to provide a molding clip which can be integrally molded easily and in-expensively by the techni~ue of injection molding of a plastic ~06S9Z4 material and which can easily be adapted to the existing process of molding attachment.
The invention in its broader claimed aspect comprehends a one-piece plastic molding clip which includes a generally planar base plate adapted to be attached on its back side by adhesive means to a window opening flange in an automobile. At least one engaging arm is attached at one end to a lower edge of the base plate and extends substantially parallel to and in spaced relation to the plane of a central portion of the base plate, the at least one engaging arm being provided at the free end thereof with a molding engaglng snap catch. At least one resilient receiving member is disposed in spaced relation to a front side of the base plate and connecting means permit it to extend from adjacent an upper edge of the base plate opposite the lower edge downwardly in spaced relation to the front side of the base plate in the direction of the lower edge and is adapted to resiliently receive an edge of a plate of glass.
With this molding clip, required attachment of a decorative and plate glass-immobilizing molding possessed of a flap portion is accomplished by joining the rear surface of said base plate through the medium of a two-face adhesive tape to the edge of the window frame, allowing the edge of the plate of glass to be set in the window frame to be supported by said resilient receiving members, setting the plate of glass in position in the window frame and thereafter bringing the molding into hooked engagement with a molding-engaging piece. This molding clip enables the plate of glass to be easily and safely attached immovably to the window frame by causing the plate of glass to be supported on one side of the edge thereof by the clip fastened to the window frame and on the other side of the edge thereof by the molding fastened to the molding-engaging nail catch. Since the clip is fastened to the window frame by means of an adhesive tape, the - positioning of the clip can easily be attained without inflicting injuries to the paint finish of the window frame. Release of B the clip from ~0659Z4 engagement with the molding can be carried out easily if it should become necessary to replace the plate of glass.
Because of the simplicity of its structure, the molding clip of the present invention can easily be integrally molded by the conventional technique of injection molding of a plastic material and can readily be adapted to the existing process for the engagement of the plate of glass and the molding.
The other objects and characteristic features of this invention will become apparent from the detailed description to be given hereinbelow with reference to the accompanying drawings.

Figure 1 illustrates a typical example of the conventio-nal molding clip, representing a partially enlarged view of awindow frame F used in an automobile for attachment of a wind-shield or a rear window.
A plate of glass G for the window is immobilized by being supported on one side by a molding M held in position by a molding clip 1 and on the other side by the edge portion of the window frame F through the medium of a packing material such as an adhesive agent.
With the conventional molding clips of such a construc-tion, studs S must be fixed by welding or some other means at prescribed positions along the window frame to permit fasten-ing of the clips to the window frame F.
The conventional molding clips are each provided at the lower central portion with an Q-shaped fitting hole 2 for receiving the head of a stud S and at the upper portion with a molding engaging nail catch 3 for permitting hooked engage-ment of the hooked portion of the molding.
With these conventional molding clips, required setting of the plate of glass is accomplished by fastening said molding clips to the window frame F while allowing the head 10~59Z4 portions of studs S to be inserted into the fitting holes 2, applying a packing material such as adhesive agent to the end portion of the window frame F, thereafter inserting the plate of glass in position into the window frame and, after the plate of glass has been get in position as described above, forcing a springy metallic molding between the window frame F
and the molding clip with the hooked portion at the leading end and bringing the hooked portion into hooked engagement ~ with the molding engaging nail catch so as to obstruct re-lease of the molding.
Since the conventional molding clips necessitate pre-paratory embedding of studs as described above, the fabrication of the window frame inevitably entails the extra work of complicated welding and the insertion of the molding may scratch paint finish of the window frame. Removal of the plate of glass fastened in position or the molding held in hooked engagement may be accomplished by breaking the molding or molding clips or by strongly pushing up the plate of glass from below (in the position of the drawing) with force enough to upset the inserted engagement between the studs S and the fitting holes 2 of the molding clips. In either case, the removal is not obtained readily.
The conventional molding clips of the construction of Figure 1 have a serious disadvantage in terms of both ease of handling and cost.
Conventional molding clips of another structure illust-rated in Figure 2 are formed each by fabricating one metal sheet in the shape o~ the letter U as shown in Figure 2(B).
As many molding clips 4 as necessary are clamped astraddle the edge portion of the plate of glass G in advance. To the peripheral edge of the window frame F, a packing material P
of adhesive agent or the like is applied in advance. As the plate of glass is fastened to the window frame F, the tongues 5 of the molding clips are allowed to be embedded into the packing material P. When the plate of glass is set in posi-tion onto the window frame F by means of the adhesive packing material P, it is ready for attachment of a molding M to the periphery thereof. This attachment of the molding is accom-plished by bringing one of the bent portions formed at theopposite ends of the molding into hooked engagement with the engaging member 6 formed by cutting and raising a portion of the molding clip in the shape of an S and bringing the other bent portion into hooked engagement with the engaging member 7 formed by bending the end portion of the molding clip. As the plate of glass G is held fast in position by the molding clips, it is resiliently held at its end portion by glass receiving pieces 8, 8.
With the conventional molding clips,of the foregoing construction, the setting of the plate of glass and the molding is effected by a method which comprises fastening the clips preparatorily to the edge of the plate of glass and fastening the plate of glass in conjunction with the molding clips onto the edge of the window frame by use of an adhesive agent applied in advance to said edge. Unexpectedly, this applica-tion of the adhesive agent requires an adva~ced technical skill on the part of the worker. In fact, the required degree of skill is so great that the method as a whole is hardly usable in an assembly line, thus depriving the method of its technical feasibility.
The conventional molding clips of the construction under discussion are produced by fabricating resilient metal sheet to shape. They, therefore, have a disadvantage that the clips eventually rust and thiS rust transfers to the automobile body and the plate of glass surface. The clips are also likely to scratch the paint finish of the automobile body if they should accidentally collide with the painted surface during the work of window assembly. Such scratches can eventually cause corrosion of the substratal metal through the marred surface.
Besides, possible variation in the size of the plates of glass and variation in window size cause a variation in the retain-ing strength of clips and, on account of close association with the rigidity of the molding in use, a gap is likely to occur between the automobile body and the molding, with the undesirably result that the molding suffers from impaired appearance and degraded quality.
In view of the various disadvantages suffered by the typical molding clips heretofore available as described above, the present invention aims to provide molding clips free from these disadvantage. Now, the present invention will be described with reference to the preferred embodiments illust-rated in Figure 3 and the subsequent figures.
A clip 11 is formed having as its main component parts a base plate 12 adapted to be laid in face-to-face contact on the wall rising from the window frame F, a springy engaging piece 13 vertically rising from the lower edge of said base ; plate and provided at the free end thereof with a backwardly projecting nail catch 15 for hooked engagement with the molding ~6592~
and resilient receiving members 14, 14 protruding from the upper edge of the base plate to the front side of the base plate (Figures 3 and 4~. Said base plate 12 functions as a base seat immobilized to the edge of a window frame and is provided with a base piece 16 protruding from the lower edge thereof perpendicularly to the front side. The clip is brought into stable engagement for snug rest at the corner portion of the edge of the window by causing the rear side of the base plate and the lower side of the base piece 16 to come into perfect contact with the two inner sides of the corner portion.
The engaging piece 13 serves to retain the molding in hooked engagement by bringing the hooked edge of the molding M into engagement with the molding-engaging nail catch 15 formed at the free end thereof. In the illustrated embodi-ment, this engaging piece 13 is formed in a rising state as if cut off and raised from the central portion of the base plate 12. The main body of the engaging piece 13 is so formed as to stand substantially past the front face of the base plate and the molding-engaging nail catch formed at the free end of said engaging piece is extended so much that the leading end thereof protrudes beyond the rear face of the base plate. The rear side of the engagillg piece 13 immedi-ately below the molding-engaging nail catch 15 is notched to form an indentation 17 and the opposite side of the engaging piece 13 from said indentation is extended to give rise to an ear piece 18 adapted to permit hooked engagement of a tool which is used for releasing the molding from its engagement with the nail catch. The resilient receiving members 14, 14 ., serve the dual purpose of receiving the edge of plate of glass G being set in the window frame and, by virtue of the pressure generated by said reception of the plate of glass, pressing said base plate against the edge of the window frame. In the preferred embodiment under discussion, they are extended from the upper edge of the base plate in a down-folded state and the extended portions are downwardly inclined toward the front so as to thrust out of the front side of the base plate, with their leading ends sharply bent up to form receiving portions 19, 19. In the preferred embodiment illustrated here, the resilient receiving members are disposed one on each side of said engaging piece 13 in a symmetrical relationship relative to said engaging piece 13. Owing to the overall arm length including the folded portion, these receiving members manifest resilience, so that the edge of the plate of glass may be snugly received by the receiving portions 19, 19 formed at the forward ends thereof. The front sides of said resilient receiving members are twisted sideways so that the inner edges of the front sides protrude in the form of ridges. When the plate of glass G is set in position as described afterward, these protruding ridges serve the purpose of preventing the edge of the plate of glass from scraping off the adhesive packing material P applied to the lower face of the plate of glass.
Thin-walled tongue pieces 20 formed on the rear side of the base plate and extending beyond the upper edge of the base plate are provided one on either side of the free end of the engaging piece. When the molding M is brought into engagement with the nail catch 15, the tongue pieces 20 are caused to i5924 come into contact with the outer side of the hooked edge of the molding M, thus serving to prevent the molding from coming into direct contact with the edge of the window frame.
Subsequently, in the clip of the construction described above, a two-face adhe~ive tape 21 is attached (or an adhesive agent may be appliedl to the rear side of the base plate 12 and the clip is pressed and fastened immovably against the rising wall of the window frame through the medium of said tape. In this case, the base plate is pressed against the rising wall only after the clip has been positionally stabi-lized by causing the base piece 16 formed at the lower edge of the base plate to fall snugly into perfect rest at the corner of the window frame. After a plurality of clips have been adhesively fastened at suitable intervals to the edge of window frame as described above, the plate of glass G having an adhesive packing material P applied in a required thickness to the lower face of its edge is poised over the array of clips and the edge of the plate of glass is slid on the front sides of the resilient receiving members 14, 14 and driven backwardly until it comes into tight contact with the receiving portions 19, 19 at the leading ends thereof while causing the pressure exerted by the edge of the plate of glass in motion to spread out the excessively applied adhesive packing material.
Consequently, the adhesive packing material buries the lower portion of the base plate 12 and the forward ends of the resilient receiving members 14, 14 and, after it is left to set, solidifies to immobilize them collectively. In this case, the possibility of the adhesive packing material P applied to the edge of the plate of glass being spread out under said pressure toward the interior portion of the plate of glass may effectively be precluded by providing the lower surface of the plate of glass with a rubber seal 22 in advance.
After the clips have been fastened to the window frame F in consequence of the adhesion of the edge of the glass of plate, the molding M is brought down to cover the clips and the hooked edge at one end of the molding is wedged in between the tongue pieces 20, 20 and the leading ends of engaging pieces 13 (Figure 4~, with the result that the wedging makes the molding-engaging pieces 15 bend forward and causes the hooked portion thereof to be brought into hooked engagement with the molding-engaging nail catch. The attachment of the molding is thus brought to completion (Figure 5). In this case, the molding M is pressed down in the direction of ex-panding the hooked edges at the opposite ends thereof so asto generate a repulsive force in the molding itself. After the molding is fastened to said molding-engaging nail catch 15, said repulsive force presses the remaining free folded edge against the front surface of plate of glass and prevents any gap from occurring between the plate of glass and the molding.
Since the molding is fastened in position as described above, the clips tend to be lifted forward or upward by the repulsive force of the molding and consequently pull in the pealing direction the base plate 12 which has already been immovably fastened to the edge of window frame through the medium of sald adhesive tape. Nevertheless, the attachment of the molding does not cause the clips to be pushed up and the prying force exerted by the molding upon the engaging 1~659Z4 piece does not peel the adhesive tape because the engaging piece serving to keep the molding directly in hooked engage-ment is connected to the lower edge of the base plate and consequently transmits the resilient force of the molding indirectly to the base plate as previously described, because said resilient receiving members 14, 14 support the edge of the plate of glass and, under the load of the plate of glass, press said base plate against the rising wall of the edge of the window frame and further because the receiving portions l9, 19 formed at the forward ends thereof are held in firm contact with the lower side of the plate of glass to offset the upward pull.
With the molding clips produced according to the present invention, therefore, even when the molding is attached before the adhesive packing material P has thoroughly solidi-fied, the clips will not come off their attached positions on the window frame F but will maintain the molding in hooked engagement therewith. Thus, the attachment of the molding can be started before the adhesive packing material has been completely solidified. This means that the work of molding attachment can be carried out very ~uickly. And the molding thus atta'ched in position to the window frame will not suffer from such undesirable phenomena as partial peeling but will insure safe fastening of the plate of glass.
The receiving portions 19, 19 of the resilient receiving members are held in fast contact with the lower side of the plate of glass and prevent the clips from lifting up. In the present preferred embodiment, they intervene between the glass and the window frame F and give rise to a fixed gap for retaining the adhesive packing material therebetween. Because of this fixed gap, a required amount of adhesive packing material remains intact in the gap in spite of the pressure which is produced when the plate of glass is mechanically inserted in position.' The adhesive packing material thus retained in the gap serves to effect adhesive attachment of the plate of glass and seals airtightly the gap between the plate of glass and the edge of the window frame.
Figure 7(A) and Figure 7(B) represent another preferred embodiment involving a partial modification with respect to the resilient receiving members 14, 14 and the base piece 16 of the preferred embodiment described above. This modification resides in omitting the formation of the receiving portions at the forward ends of said resilient receiving members and instead enlarging the base piece 16 for thereb,v forming on the upper side thereof a pillow 23 for supporting the lowe,r side of the plate of glass.
In this preferred embodiment, the base piece serves to stabilize the attachment of the base plate 12 as described previously and the pillow 23 formed on the upper side thereof supports the lower side of the plate of glass and prevents the plate of glass from sinking further down and insures undis-turbed retention of the adhesive packing material. At the same time the base piece becomes buried itself under the pool of adhesive packing material and consequently immobilizes the clip as a whole. When the molding is attached to the clip, the base piece which is held in tight contact with the lower side of plate of glass prev'ents the clip from lifting up and also serves the purpose of preventing the adhesive tape from ~065929~
peeling off. The preceding preferred embodiment requires the adhesive tape to be applied to the rear side of the base plate. Owing to the enlargement of the area of the base piece, the present preferred embodiment can immobilize the clip by means of an adhesive tape applied to the lower side of the base piece.
Figure 8 through Figure 10, incl. represent modifications to the preferred embodiments described above. The preferred embodiment of Figure 8 has engaging pieces disposed one on either side of the base plate 12, that of Figure 9 has resili-ent receiving members 14, 14 extending between the upper edge of the base plate 12 and the receiving piece 16 with their respective opposite ends integrally connected to the upper edge of the base plate 12 and the receiving piece 16 and that of Figure 10 has resilient receiving members 14, 14 of the preferred embodiment of Figure 9 cut off at the upper ends thereof from the upper edge of the base plate and supported exclusively by the receiving piece. All these pxeferred embodiments produce identical effects to those obtainable by the preferred embodiments illustrated in Figure 3 through Figure 6, Figure 7(A) and Figure 7(B).
To enhance the safety o~ the attachment of the molding and the plate of glass, the present invention also provides a molding clip of a construction that will now be described.
By way of example, there will first be considered a case in which the molding clip of this invention illustrated in Figure 3 breaks loose from engagement owing to inferior workmanship during the attachment of the molding and the plate of glass. This problem will be discussed with reference o~
10659Z~
to Figure ll.
In the initial stage of the insertion of plate of glass, when the edge of plate of glass comes into sliding contact with the resilient receiving members l9 and forces the resi-lient receiving members to bend in the direction of the frontsurface of the base plate 12, the resilient receiving members are subject to the downward force exerted by the edge of the plate of glass. Since this downward force functions as a counterclockwise moment in the entire clip, the upper portion of the base plate tends to depart from the window frame F, the lower portion thereof tends to press the adhesive tape toward the interior and the clip ll tends to incline down wardly in the front direction and break loose from the window frame. Since the work of wedging the molding in between the engaging piece 15 and the tongue piece is carried out before the adhesive packing material P applied to the edge of the plate of glass has been thoroughly solidified and since the hooked edge of the molding M repulses the engaging piece 15 toward the front side, a force is additionally exerted to remove the clip from the aforementioned state. Consequently, the adhesive tape is peeled off the clip's base plate or the window frame and the clip may possibly break loose. This trend is particularly conspicuous when the substrate of the adhesive tape is made of a material deficient in resilience.
This is because the inclination of the base plate increases and the distance between the upper edge of the base plate and the edge of window frame consequently increases in propor-tion as the amount of deformation of the adhesive tape increases, - ~06S924 For this reason, the preferred embodiments of the present invention to be described hereinbelow each have provided at the lower portion of the rear side of base plate with a protrusion having a height equal to or slightly smaller than the thickness of the tape 21 being used. When the aforemen-tioned force develops and tends to exert its impact, said protrusion stops itself against the edge of the window frame, bears-the force and prevents the clip from inclining down-wardly toward the front side and breaking loose from the engagement.
Figure 12 illustrates a preferred embodiment in which protrusions 24, 24 having a height slightly smaller than the thickness of the adhesive tape 21 are formed along the lower edge and upper edge of the rear side of the base plate 12 and the adhesive tape 21 is applied to the rear side of the base plate between the two protrusions. In this case, in the initial stage of the insertion of plate of glass, namely while the resilient receiving members 14 have not yet been bent by the edge of the plate of glass in the direction of the base plate 12, the force exerted by the edge o~ the plate of glass is received by the upper edge of the base plate at which the resilient receiving members are attached to the base plate. As a result, the upper edge of the base plate is moved in the direction of the window frame. The protrusion 24 formed along the upper edge serves to prevent such move-ment of the upper edge of the base plate. The protrusion 24 formed along the upper edge, however, fails to fulfil the purpose of bearing the force exerted during the insertion of the molding and, for that reason, may be omitted. The protru-.' ~0659Z4 sions are not always required to be formed continuously as illustrated but may instead be formed in segments, for example, in two segments falling one on each end or in three segments of which two fall one on each end and the remaining one falls at the center; Presence of the protrusion 24 prevents the adhesive tape from exposure.
If these protrusions are formed on the rear side of the base plate in the portions which have heretofore been used for application of the adhesive tape 21, then the area availa-ble for application of the adhesive tape is decreased by the area occupied by the protrusions and the strength of attach-ment to the window frame is proportionally decreased. Such undesirable decrease may be eliminated by increasing the area of the base plate enough to provide the same area for appli-cation of the adhesive tape. If the size of the window opening in the direction of depth, namely the size of the base plate in the vertical direction, is limited, then the problem may be solved by forming extended portions 25 one each at the opposite ends of the base plate as illustrated in Figure 14 or Figure 15 and further forming protrusions 24 each at the lower ends of the rear sides of said extended portions 25.
According to the molding clips of the present invention, in the initial stage of the insertion of the plate of glass, when the edge of the plate of glass pushes and bends the resilient receiving members 14 in the direction of the front side of the base plate, the moment exerted on the base plate of the clip tends to cause the lower portion of the base plate to press the adhesive tape and make the base plate incline downwardly toward the front side. However, the protrusions 24 bear this force and keep the adhesive tape from being pressed down, so that the base plate hardly in-clines (Figure 13). Thus, the possibility of the base plate breaking loose from the attachment with the edge of the window frame is completely eliminated. Similarly, the force which tends to pry the base plate out of the window frame during the insertion of the edge of molding into the engaging piece is supported by the protrusions 24. Thus, the possi-bility of the clip breaking loose from the engagement byvirtue of this force is perfectly prevented.
The illustrated preferred embodiments of this invention have been dçscribed. The clips of the present invention are temporarily fastened individually to the edge of the window frame by means of an adhesive tape or adhesive agent and `thereafter are collectively immobilized by utilizing the ad-hesive agent being used for adhesive engagement of the plate of glass. The attachment of the plate of glass and the mold-ing by use of the clips of this invention, therefore, can be effected quite efficiently as compared with the conventional method which involves preparatory attachment of studs for footing, for example, and without the possibility of rusting.
Furthermore, the engaging piece intended to permit hooked engagement of the molding is extended from the lower edge of the base plate as described above and the engaging piece itself is vested with ample resilience and is permitted to function substantially independently. Consequently, if the molding is brought into hooked engagement before the adhesive agent has been thoroughly solidified, the resilient force of the molding will neither cause the adhesive tape to come off or move out of position nor make the molding break off from the fast engagement. Thus, the clips of this invention have an advantage that the work of attachment can be performed quickly.
Further, since the aforementioned engaging piece is formed so as to enjoy freedom of deformation, desired re-placement of the molding alone can be obtained by forcibly lifting the edge of the molding held in pressed contact with the front side of plate of glass by a suitable tool, insert-ing through the opening a prier or some other tool having a hook at its leading end, hooking the prier on the ear portion or recess formed in the engaging piece, pulling the prier to bend the engaging piece toward the front side and thereby breaking the engagement of the molding with the engaging piece. In this case, the removal of the molding by the procedure described above can be accomplished without in-flicting any damage on the clip. Thus, the clips can be used again. Reusability of clips proves highly advantageous for the purpose of replacement of the molding or of adjustment to be required during the attachment of molding.
