Clamp for headwear and other objects

Abstract

A clamp for headwear and other objects. The clamp includes a movable arm pivotably coupled to a fixed arm, which is coupleable to a surface. An object can be inserted into the gap between the lower ends of the two arms. A spreader element in an extended position maintains the lower ends of the arms spread apart. A spring exerts a force on the upper ends of the arms so as to push the lower ends of the arms together. Insertion of an object into the gap moves the spreader into a withdrawn position, allowing the lower ends of the arms to grip the object. Pushing the upper ends of the arms together releases the object and replaces the spreader element in the extended position.

DETAILED DESCRIPTION

[0020] Aspects of the invention are disclosed in the following description and related drawings directed to specific embodiments of the invention. Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention. Further, to facilitate an understanding of the description discussion of several terms used herein follows.

[0021] As used herein, the word exemplary means serving as an example, instance or illustration. The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiment are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms embodiments of the invention, embodiments or invention do not require that all embodiments of the invention include the discussed feature, advantage or mode of operation.

[0022] According to one exemplary embodiment, and as shown in the Figures, a hat-retaining clamp is disclosed. The clamp includes a pair of arms, a movable arm 1 and a fixed arm 2, arranged in front-to-rear relation, with their inner surfaces facing each other. The arms 1 and 2 are pivotably coupled by a hinge 8, pivoting about the longitudinal axis of hinge 8. The fixed arm 2 may be coupled to any surface, for example a closet door or a wall, by any desired means, such as, for example, mounting pads 4 and 5. The mounting pads can be secured to fixed arm 2 by an adhesive, while the outward-facing surface of the mounting pads can also include an adhesive, which is covered by a release liner until ready for use. At that time, the liner is removed and the clamp can be pressed into place on a mounting surface. Alternatively, the clamp can be mounted on screws that are received in corresponding keyhole slits (not shown) defined in fixed arm 2. The surface to which the clamp is mounted may be a vertical surface, an angled surface, or otherwise oriented in any direction that enables the clamp to function as described herein.

[0023] FIG. 3 is a side view of the clamp in a partially open configuration. Such a configuration would not occur statically in normal operation, but is shown here for clarity in the relationship of the component parts. A resilient member, for example compression spring 11, applies force to spread the upper ends of arms 1, 2 apart, thereby closing the lower ends of arms 1, 2 as the arms pivot about hinge 8. The lower end of movable arm 1 has a pad 6, which may be convex, while the lower end of fixed arm 2 has a pad 7, which may be concave. Pads 6 and 7 are gripping members that serve to grip the brim of a hat while also providing some protection and cushioning to the hat brim surface. The gap 18 between the lower ends of arms 1, 2 provides the space for insertion of the brim.

[0024] A spreader 13, shown here in an intermediate position, may be a rod, a flap, or the like, and is pivotably coupled to movable arm 1 via pivot 17. A first end of spreader 13 is coupled to hinge 17, while the opposite end of spreader 13 is free and influenced by gravity, such that when it is not constrained, the spreader pivots towards a stop 14. Stop 14 is disposed on the inner surface of fixed arm 2. The distance between hinge 8 and stop 14 may be slightly greater than the distance between hinge 8 and pivot 17. Optionally, a groove 19 extends transversely across fixed arm 2 and is disposed proximate stop 14. While in this embodiment, spreader 13 is coupled to movable arm 1 while stop 14 and groove 19 are at fixed arm 2, the location of these elements could be switched between the two arms without detracting from the functionality of the clamp. Alternatively, stop 14 and spreader 13 may be positioned on the same arm, such that, when stop 14 engages spreader 13, the free end of spreader 13 is disposed slightly below pivot 17.

[0025] In some embodiments, the upper and lower ends of movable arm 1 may be angled with respect to the central portion of arm 1. The upper end of movable arm 1 may be angled towards fixed arm 2, so as to provide a more convenient range of movement for the user's finger as it depresses the upper end of arm 1. The lower end of movable arm 1 may be angled away from fixed arm 2, such that when the clamp is in a closed configuration, the lower end of movable arm 1 is substantially parallel to, or almost parallel to, the lower end of fixed arm 2. Such a configuration allows for greater surface contact between the gripping pads and the hat brim, thereby increasing the clamping force on the hat brim. An exemplary range of the angles between the ends of arm 1 and the central portion of arm 1 may be approximately 0-10, but would depend on the geometry of the particular implementation of the embodiments disclosed herein.

[0026] FIG. 4 is the cross-sectional view of arms 1, 2 along line A-A of FIG. 3. While the dimensions shown are such that the two arms could nest within one another when closed, the operation is such that such a condition does not occur. Both arms could have the same width, however, if the portion where the arms are joined at hinge 8 were adjusted to prevent interference between the arms. While the arms are both shown here with slight flanges to provide strength against bending, the need for the flanges, as well as the dimensions thereof, will depend on the material used.

[0027] FIG. 5 shows a rear view of movable arm 1, showing the interior surface thereof. Seen here are the interior surface 1a, compression spring 11, hinge 8, pad 6, and spreader 13 with its pivot 17.

[0028] FIG. 6 shows an alternate embodiment of the clamp shown in FIG. 3. In this alternate embodiment, the resilient member is a torsional spring 12 instead of compression spring 11. Both types of spring can serve the same purpose, which is to keep the upper ends of arms 1, 2 spaced apart and the lower ends of arms 1, 2 gripping the brim of an inserted cap or hat. Any other kind of resilient member that allows the clamp to function as described herein may also be used and positioned accordingly.

[0029] FIG. 7 shows another alternate embodiment of the clamp. wherein the gripping members are soft caps 9 and 10 that cover the ends on the lower ends of arms 1 and 2, respectively. These caps are typically produced by dipping the ends of the arms in a liquid compound and likewise serve to grip and help prevent damage to the brim. Any other gripping members that allow the clamp to function as described herein may be contemplated and provided as desired. FIG. 7 further shows a second resilient member, for example a torsion spring 20, engaging the spreader 13 so as to impart a downward force to spreader 13. This can provide additional force to move the spreader into the extended position, which may be useful if the clamp is mounted on a non-vertical surface. It should be understood that this second resilient member may be used with any embodiments of the clamp described herein.

[0030] The next four figures show a sequence of operation.

[0031] FIG. 8 depicts a side view of the clamp an open configuration, with a hat brim 15 being inserted into the gap 18 between pads 6 and 7. The spring 11 is fully compressed and thus providing its greatest force urging the top of both arms to separate. However, the jaws are prevented from closing by spreader 13, which is disposed in an extended position and is pressing against the inside surface of fixed arm 2 while resting on the stop 14. In the extended position, the free end of spreader 13 can also abut groove 19 of fixed arm 2, with the groove providing a detent on the inner surface of the fixed arm, imparting additional stability to spreader 13 in this position.

[0032] FIG. 9 shows the clamp in a closed configuration. The inserted brim 15 has pushed spreader 13 upwards, placing the spreader in a withdrawn position and thereby allowing the lower ends of the arms to close on the brim. The brim is held securely by pads 6, 7 due to the force exerted by spring 11 on the upper ends of the inner surfaces of arms 1, 2. A smoother and less resistant motion of the spreader 13 may be facilitated by a low-friction material disposed on the inside surface of fixed arm 2, on the free end of the spreader, or both. Alternatively, the spreader itself may be formed from a low-friction material.

[0033] FIG. 10 illustrates a configuration of the clamp when a user's finger 16 pushes on pad 3 of movable arm 1, thereby compressing spring 11 and opening the lower ends of the arms. The brim 15 is released and can drop out under the weight of the hat. Furthermore, spreader 13 drops under the effect of gravity, or of spring 20, to engage stop 14, which prevents further downward travel of the free end of the spreader.

[0034] FIG. 11 depicts the clamp in the open configuration, when the finger is withdrawn completely. The lower ends of the arms are now completely open, and held open by spreader 13 being in the extended position and engaging the inside surface of fixed arm 2. It should be noted that the positioning of stop 14 may be below axis 17. Consequently, the distal end of the spreader 13 is below its pivoting axis 17, thereby producing a downward force on the spreader and stabilizing the open configuration.

[0035] Variations to the design of the described embodiments, with respect to dimensions, shape, arm travel distance, spring type, arrangement of elements, and so forth, may be contemplated and provided as desired without departing from the scope and spirit of the invention. For example, in some embodiments, the spreader may be provided as a hinged member pivotably coupled to both arms, with a hinge therebetween. In the extended position, the spreader hinge may be disposed slightly below the pivots, spreading the lower ends of the arms apart. In the withdrawn position, the spreader hinge may be disposed above the pivots, allowing the lower ends of the arms to be brought together. Furthermore, while the embodiments disclosed herein are described as being used with brimmed hats, it should be understood that the invention may be used with any type of object, including apparel and non-apparel items, that allows the invention to function as described herein.

[0036] The foregoing description and accompanying figures illustrate the principles, preferred embodiments and modes of operation of the invention. However, the invention should not be construed as being limited to the particular embodiments discussed above. Additional variations of the embodiments discussed above will be appreciated by those skilled in the art.

[0037] Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive. Accordingly, it should be appreciated that variations to those embodiments can be made by those skilled in the art without departing from the scope of the invention as defined by the following claims.
