,TagSPECI:TECHNICAL FIELD
Embodiment of present disclosure broadly relates to an assembly used for opening and closing of a cut-out. In particular relates to an assembly which is used for opening and closing of tow hook cut-out in a bumper of a vehicle.

BACKGROUND OF THE DISCLOSURE AND PRIOR ARTS
It is known to close cut-outs or openings of a vehicle part in many different ways to access the part when needed. As an example, a tow hook cut-out is one of the cut-out which is required to be opened when needed. By opening the tow hook cut-out, a tow hook in the vehicle is accessed for towing purpose when the vehicle is in breakdown or any other condition in which the vehicle is not in a position to drive through to the garages or service centres. During normal working condition of the vehicle, the tow hook needs to be closed or masked for increasing aesthetic look of a bumper of the vehicle and thereby to increase the overall look of the vehicle. There are plethora of tow hook exists, which serves the purpose of closing or covering the tow hook opening or cut-out.

One kind of tow hook cover that exists is a swivel or pivot type closer as shown in Figs. 1 and 2. The tow hook cut-out is opened by removing the swivel type of closer manually by applying pressure. The closer is removed from bumper by force insertion on one edge while other edge pops up by swivelling. While closing the cut-out, the cover/closer placed into the cut-out and connected using a snap fit arrangement. The snap fitment isn’t very strong and results in loose fitment sometimes. Thus, the tow hook cover or closers are sometimes hangs or missing tow cover during road usage resulting from low force snap fitment & lack of positive mounting. Also, the swivelling type covers often have been associated with a limitation such as see through gaps which are not aesthetically good in look. Sometimes, the cover might also be fallen due to no positive locking mechanism in the covers.

Another kind of tow hook cover exists is a flip open type cover as shown in Figs. 3 and 4. These kinds of tow hook covers are mounted in the cut-out using a snap fit mechanism and are removed for accessing the tow hook by lifting the cover manually using any tool such as screw drivers. A slot cut is provided in the tow hook cover which will be used for lifting or opening the cover. The limitation associated with this kind of tow hook cover is that, as the tow hook cover is provided with a slot cut, the slot cut does not provide aesthetic look to the bumper cover. Also, while removing the cover using screw drivers, paint made in the bumper would get damaged.
Further, as shown in Figs. 1 and 3, the tow covers are provided with an arrow shaped hook which is linked to base bumper. When the tow hook cover is removed for towing purpose, the tow hook cover hangs on a bumper skin with the help of the arrow shaped hook. The limitation of these kinds of covers is that, the cover may fall out of the attachment or bumper when the towing operation is carried out due to vehicle’s vibration and thereafter the bumper may appears to be as without tow hook cover. Thus, the aesthetic look of the bumper may be spoiled without the tow hook cover in the bumper.

In addition to the above, the exiting tow hook covers have issues of non-uniform flushness due to dynamic part conditions i.e. opening and closing in absence of positive mounting.

In view of the above limitations, there exists a need to provide a closure assembly which would overcome the limitations set by the prior arts.

The assembly disclosed in the present disclosure is used for concealing a cut-out in a member of a vehicle. The assembly comprising a cover pivoted about its periphery on a member having the cut-out, such that the cover is rotatable angularly for regulating opening and closing of the cut-out. A support arm is provided in the assembly which abuts the cover. The support arm is pressed onto the cover by a spring loaded fastener which is provided in the pivoted point of the cover. Further, a stopper is configured at surface of the member for preventing rotation of the cover beyond a pre-set angular rotation. The assembly can be further provided with a snap lock which is configured at periphery of the cover for locking with a lock rib configured on the member for locking of the cover at a pre-set angle. The assembly is provided with at least one protection rib which is configured on the surface of the member for keeping the cover offset with the surface of the member to prevent sliding contact of the cover on the surface of the member during opening and closing of the cut-out. The protection rib is located below peripheral surface of the cover for keeping the cover offset with the surface of the member to prevent sliding contact of the cover on the surface of the member during opening and closing of the cut-out.

Fig. 5 illustrates a perspective view of the assembly (10) when the support arm (12) is not in an assembled position with the cover (11) and Figs. 6a and 6b illustrates perspective views of the assembly (10) when the support arm (12) is assembled onto the cover (11) according to embodiments of the present disclosure. The assembly (10) for concealing an cut-out (21) in a member (20), for example in a vehicle, comprises a cover (11) pivoted about its periphery on a member (20) having the cut-out (21), such that the cover (11) is rotatable angularly for regulating opening and closing of the cut-out (21). Further, a support arm (12) is provided in the assembly (10) which abuts the cover (11). The support arm (12) is pressed onto the cover (11) by a spring loaded fastener (14) which is provided in the pivoted point of the cover (11). In one embodiment, the support arm (12) can be molded with the cover (11) and can be manufactured in a single mold. The cover (11) and the support arm (12) are connected by way of a hinge (15). In one embodiment, the hinge (15) can be any kind of hinge which serves the purpose and the hinge (15) may be but not limited to a live hinge. The live hinge is a single moulded part with no relative motion between the cover (11) and the support arm (12) as they are moulded together. In one embodiment, the support arm (12) may be separately moulded and assembled with the cover (11) with a spring loaded fastener. Other than live hinge, the support arm (12) can be separately moulded and assembled with cover (11) with a spring loaded fastener. However, with live hinge, a single moulded part with no relative motion between the two is achieved as they are moulded together. If a separate support is used then the linear motions of support arm (12) are restricted by the spring loaded fastener. To arrest angular movement of the support arm (12) around the fastener, restricting ribs (42) are provided. The restricting ribs (42) also support in live hinge type design for restricting the angular movement of support hinge arm.

At least one stopper (16) is also configured on surface of the member (20) for preventing rotation of the cover (11) beyond a pre-set angular rotation. The pre-set angle may be provided in such a manner that the cut-out (21) in the member (20) is substantially opened for accessing to parts located inside the member (20). In one embodiment the pre-set angle can be in the ranging from 0 to 100 degrees either sides.

In one embodiment, the cover (11) for opening and closing of the cut-out (21) of the member (20) conceals the cut-out (21) when it occupies the cut-out (21) completely as shown in Fig. 6b. The shape of the cut-out (21) substantially matches with the shape of the cover (11) excluding the collar (11a) (shown in Fig. 6c) portion. In one embodiment, the shape of the cut-out (21) and cover (11) can be but not limited to circular, rectangular, square or any other geometric or non-geometric which serves the purpose. In one embodiment, the collar (11a) at periphery of the cover (11) conceals the cut-out (21) without leaving any see through gaps between the member (20) and the cover (11) as shown in Fig. 6c.

In one embodiment, the support arm (12) is moulded arm with the cover (11). The support arm (12) is hinged (15) with the cover (11). Also, the support arm (12) is mounted onto the cover (11) such that the support arm (12) always exerts pressure onto the cover (11). This will also help in concealing the cut-out (21) in closed position. The pressure is exerted by the support arm (12) by a spring loaded fastener (14) located at the hole (14a) provided at the vicinity of the hinge (15). The support arm (12) upon rotation about the hinge (15) conforms to upper portion of the cover (11). Thus the cover (11) and support arm (12) forms a single entity for concealing the cut-out (21) of the member (20). The spring loaded fastener (14) is provided in such a way that the assembly (10) of the cover (11) and the support arm (12) can be pushed from outside surface or ‘A’ surface of the member (20) as shown in Fig. 7.

Fig. 7 illustrates a front perspective view of the assembly (10) when mounted with a member (20) and when the cover (11) is in a closed position and Fig. 8 illustrates a rear view of the assembly (10) when mounted with a member (20) and when the cover (11) is in closed position according to an embodiment of the present disclosure. With reference to Fig. 7, for opening the cut-out (21), the cover (11) needs to be pushed gently and manually in the direction ‘X’, which is perpendicular to the plane of the surface ‘A’ of the member (20). The cover (11) is pushed until the depth, which is corresponding to the height of the protection rib (22) (more clearly shown in Figs. 9 and 10). Also, when the cover (11) is pushed till the collar (11a) portion is released from the cut-out (21), and can now the cover (21) be moved angularly. Thereafter, the cover (11) is rotated angularly in any one of the directions R1 and R2, for opening the cut-out for accessing the internal parts of the assembly (10). The protection rib (22) is configured in such a way that the starting point in the protection rib (22) is having minimum height so as to raise the cover (11) during its angular rotation. Also, the protection rib (22) maintains a minimum height which would be sufficient to keep the cover (11) offset from the surface ‘B’ of the member (20).

In one embodiment, the member (20) may be a substantially flat or plate structure which forms a platform or a substrate for mounting the assembly (10). The assembly (10) is mounted onto surface of the member (20) at a location where the cut-out (21) is provided. In an exemplary embodiment, the member (20) can be a vehicle bumper in which a cut-out for accessing the tow hook for the towing device is provided, which will be slightly curved surface as that of bumper styling curvature.

Figs. 9 and 10 illustrates a rear perspective views of the assembly (10) when mounted with a member (20) and when the cover (11) is in closed position according to an embodiment of the present disclosure. In one embodiment, the assembly (10) is further provided with at least one snap lock (17) configured at periphery of the cover (11) for locking with at least one lock rib (18) configured on the member (20) for locking of the cover (11) at a pre-set angle. In one embodiment, at least one protection rib (22) is configured on the surface of the member (20) for keeping the cover (11) offset with the surface ‘B’ (shown in Fig. 8) of the member (20) to prevent sliding contact of the cover (11) on the surface of the member (20) during opening and closing of the cut-out (21). In one embodiment, the at least one protection rib (22) is located below peripheral surface of the cover (11) for keeping the cover (11) offset with the surface of the member (20) to prevent sliding contact of the cover (11) on the surface of the member (20) during opening and closing of the cut-out (21). Thus the protection rib (22) prevents any damage that could cause to the member surface due to sliding movement.

Fig. 11 shows a cross sectional view of the assembly (10) with the member (20) as shown in Fig. 8 according to an embodiment of the present disclosure. The member (20) is provided with a dog house (41) to facilitate connectivity of the assembly (10) with the member (20) using spring loaded fastener (14). The cover (11) conceals the cut-out (21) during fully closed position. The dog house (41) also avoids cosmetic defect on surface “A” of the member (20) commonly known as sink mark. In absence of the dog house (41), a direct boss is used on a surface “B “of the member (20) to mount the spring loaded fastener. The mounting of the boss would result in sink mark on surface “A” due to higher wall thickness ratio of the boss to the member (20).

Figs. 12 to 15 illustrates various views of the assembly (10) when mounted with a member (20) and when the cover (11) is in partially opened position, according to an embodiment of the present disclosure. The assembly (10) operated for opening of the cut-out (21) by firstly pushing the cover (11) inside the surface of the member (20); and thereafter, secondly, rotating the cover (11) to open the cut-out (21). In one embodiment, the actions pushing and rotation is carried-out manually.

Figs. 16 to 19 illustrate various views of the assembly (10) when mounted with a member (20) and when the cover (11) is in fully opened position, according to an embodiment of the present disclosure. After pushing the cover (11), it is rotated in any predetermined direction for opening the cut-out (21) to more accessible area. Due to pushing and concurrently rotating the cover (11), the cover (11) is placed onto the protection rib (22) and overrides the protection rib (22). Upon further rotation of the cover, the snap lock (17) of the cover (11) reaches the lock rib (18) configured in the member (20) and gets locked with the lock rib (18). Thus, the snap lock (17) and the lock rib (18) provide a positive and anti-slip lock when the cut-out (21) is substantially opened by the cover (11). In one embodiment, the member (20) is provided with plurality of stoppers (16) which restrains rotations of the cover (11) further when the cover (11) is lifted back from the lock rib (18) for closing the cut-out (21).

Figs. 20a and 20b illustrate a front view and perspective view of bumper (30) of a vehicle incorporated with the assembly (10) for opening and closing of the tow hook cut-out (40) according to an embodiment of the present disclosure. The tow hook (not shown) is accessed by opening the cover (11) of the assembly (10) manually.

Also variable height and geometry of the ribs near closing position on tow cover, help in guiding movement toward final closed position as the operation is blind and needs guiding.

Further, since the cover (11) does not come off from the member (20) when the cut-out (21) is open, there is no possibility of misplacing the cover (11).

Industrial applicability
In one embodiment, the assembly disclosed in the present disclosure finds its potential application in vehicle or automotive tow hook cover. Also, the assembly might find its application in automobiles which are all types of surface or road vehicles and air transport vehicles.

Equivalents
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
