Abstract
A jointed clamp for attachment to an inside portion of the top of a garment bag has a pair of clamp jaws pivotal connected at their back ends with a hinge pin, and a latching device for releasibly securing the clamp jaws in a closed position. Each of the clamp jaws includes an elongate U-shaped channel, a resilient block seated in the channel and a transversely extending rivet located at the front end of and extending through the resilient block and channel walls. A vertical member is mounted in and extends between the two clamp jaws in a rearward portion thereof, forward of the hinge pin. The resilient block contacts the vertical member which prevents rearward longitudinal movement within the channel. One of the clamp jaws is provided with a plurality of indentations to hold the hooks of coat hangers, and this same clamp jaw is also provided with a vertical tab in the front portion thereof which engages the front end of the seated block.
Description




FIELD OF THE INVENTION




The present invention relates in general to holders that are mounted inside a garment bag and that hold the hooks of one or more garment hangers on which different items of clothing are hung, the garments being housed in their entirety within the garment bag. In particular, the present invention relates to an improved construction in a jointed clamp that can be mounted inside a garment bag.




BACKGROUND OF THE INVENTION




The present invention is an improvement on jointed clamps used inside garment bags and disclosed in U.S. Pat. No. 4,252,220 reissued as Re 31,075; No. 4,363,388 issued Dec. 14, 1982, 5,590,765 issued Jan. 7, 1997, and 5,887,710 issued Mar. 30, 1999, all incorporated herein in their entirety by reference. In each of these patents, the jointed clamp grasps the hooks of the hangers and is mounted depending downwardly to an inside top portion of, and located entirely inside o, the garment bag. A similar jointed clamp that is a hanger lock and mounted on top of a garment bag so as to grasp the stems of hangers to keep them from falling within the garment bag is disclosed in U.S. Pat. No. 3,566,456 issued Mar. 2, 1971, incorporated herein in its entirety by reference. The present inventor is an inventor in each of these patents.




Garment bags have come into extensive use in recent years and are generally of the type having flexible walls and a cover with a closure means such as a zipper to provide an enclosed housing for garments. The bags are usually provided with means on the top thereof for suspending the bag while loading and unloading the same with garments of long lengths that are usually mounted on a hanger. The garment bag is provided with a clamp that receives and fixedly holds the hanger. Once loaded, the garment bag can be folded for more convenient transport or carried in an extended condition Examples of such garment bags, of which there are many, Garment bags are also disclosed in the following U.S. patents, each of which is also incorporated herein by reference: 3,958,675; 3,221,848; 2,862,586; 2,689,631; 2,671,706; and 2,606,636. These bags also provide examples of the various types of features available with such bags and examples of different mechanisms for retaining the clothes hangers inside the bag. Another example of a jointed clamp is depicted in U.S. Pat. No. 4,640,414, incorporated herein by reference.




Each of the mechanisms for retaining the clothes hangers has various problems and defects. For reasons explained in the above cited U.S. Pat. No. 4,363,388, the clamp disclosed therein (hereinafter referred to as the “388 clamp”) overcomes many of the problems of the prior art devices.




The 388 jointed clamp has been manufactured and used successfully in garment bags for over 15 years. Such clamps are comprised of an upper channel hinged portion rigidly mounted to the top of a garment bag, a lower channel hinged portion, and a hinge pin extending through a rear portion. Each channel had substantially parallel walls connected by a corresponding top or bottom. Seated in each respective channel is a resilient block of a yieidable material such as rubber. Each channel wall has a vertical slot adjacent the ends of the blocks to facilitate the turning of the terminal edges of the lateral walls to bite into the side surfaces of the blocks along the open faces, without distorting the alignment between the components of the clamp. This retains the block in the channel. Each block protrudes beyond the open faces of the channels and is further retained in its respective channel by being wedged between a rev post and a forward tab that has been bent inwardly from the corresponding bottom or top of the channel so as to bite into the ends of the corresponding resilient blocks. Obviously, the provision of side wails that can be squeezed into an inserted block requires e steps and costs in the manufacturing thereof




While generally such jointed clamps have very successfully accomplished their intended purposes, after a period of successful usage, some of the blocks have become loose and occasionally fall out of the channel, thereby rendering not only the jointed clamp unusable, but also the entire garment bag unusable.




Thus, a jointed clamp is needed in which there is a mechanism for retaining the block in its respective channel over many years of usage so that a minor component does not render the entire bag useless. Although the problem was reported to the inventor, the first difficulty was to establish the cause thereof. This was not easy because the problem did not present itself in newly manufactured joint clamps, and most worn clamps were not available for inspection. Thus, a lot of experimentation was done in order to try to simulate the problem of the block not being retained. Many different designs were attempted, including trying different materials, adding an additional rear tab to bite into the block, having different shaped channels, and redesigning the hinge coupling. Occasionally one design or another seemed to have solved the problem, but the solution often caused a significant increase in the cost of manufacturing the clamp. An inexpensive solution that worked was needed, but was difficult to find.




SUMMARY OF THE INVENTION




The present invention provides a solution to the aforementioned long felt, but unsolved need and the disadvantages of the prior art clamps. The solution is both simple in concept and implementation so that not only does the holding blocks remain retained with the corresponding channel throughout the life of the clothing bag, but the added cost is not significant with respect to the overall cost of the clamp. In fact if the savings of various other features which could be eliminated are considered, the implementation of the present invention actually reduces the manufacturing cost of the clamp.




The present invention is directed to a jointed clamp comprising an elongate, U-shaped upper channel, an elongate, U-shaped lower channel, and a hinge pin connecting a rear end of each channel to each other so that they can pivot with respect to each other. In one embodiment of the present invention, a clasp is mounted at a forward end thereof to a forward end section of the lower channel, and is capable of engaging the forward end section of the upper channel. In a more specific embodiment, the clasp includes a handle with a wire loop pivotally mounted thereon, the wire loop bang capable of fitting around the upper channel.. In all embodiments, an upper and lower resilient block is mounted in a corresponding channel and is retained therein by a transverse rivet located in the forward half of each block. A vertical stem or rod is mounted in and extends through and terminates beyond a rear section of each channel and limits the angular opening between the two channels with the result of keeping the rear sections of each block in close proximity to each other so that the rear section of one block retains the rear section of the other block in the channel. In addition, the vertical stem abuts the back end of each block so as to prevent fore and aft movement within the corresponding channel. The lower channel has a vertical tab that abuts the front end of the lower block. Thus, the blocks are retrained in each channel.




A jointed clamp according to the present invention has a single rivet per channel that is used to retain a block therein and eliminated the need for vertical slots in the walls of the channels that are necessary so that an inner section of the chapel walls can be turned into a seated block to forcibly retain it in the channel.




Other features, advantages and benefits of the present invention, are set forth in or obvious from the detailed description of the invention hereinbelow.

, also extend through mounting plate


30


and rigidly mount mounting plate


30


to bag


10


. Jointed clamp


5


is comprised of an upper clamp jaw or channel


40


and a slightly wider lower clamp jaw or channel


50


. Each channel has a font end portion, a middle portion and a back end or rearward portion. The rearward end of upper channel


40


is pivotally joined to the rearward end of lower channel


50


by a hinge member


65


that can be a hinge pin or a rivet, the rearward ends of upper channel


40


fitting between and being received by the rearward ends of lower channel


50


. Hinge member


65


extends beyond the external walls of the channels


40


and


50


. Upper channel


40


is comprised of a web


41


and integral, spaced-apart and opposed substantially parallel lateral walls


42


extending therefrom which form an open face opposite web


41


. As shown in

FIG. 3

, lower channel


50


has a complementary configuration and is displaced congruously to upper channel


40


. Thus lower channel


50


is comprised of a web


51


and integral, spaced apart and opposed substantially parallel lateral walls


52


to present an open face above web


51


. A sleeve (not shown) surrounds hinge member


65


between the internal sides of opposed lateral walls


42


and


52


of channels


40


and


50


and reenforces the pivotal joint of hinge member


65


.




Respectively mounted in channels


40


and


50


are elongated blocks


45


and


55


that are made of a resilient or yieldable material such as rubber or a plastic material having similar characteristics. Blocks


45


and


55


each have a rectangular cross-section with a planer front, a planar back, planer sides, a planar top and a planar bottom, .and are of the same material. Blocks


45


and


55


have similar dimensions, except that upper block


45


is slightly thinner than lower block


55


so that it can be accommodated in a narrower channel, and is slightly shorter than lower block


55


. Blocks


45


and


55


are seated in each respective channel


40


and


50


for all of their length and vertical portions thereof protrude beyond the open faces of channels


40


and


50


. As shown in

FIG. 3

, the upper face of lower block


55


has a plurality of transverse indentations or grooves


56


provided along the length thereof which can retain one or more hooks of hangers and impede the movement of the hooks of hangers along the length of lower block


55


.




A simplified stop mechanism for restricting the angular or pivotal movement between pivoted channels


40


and


50


of clamp


30


is provided by a vertical member, such as a rod or stem


46


. Stem


46


has flanged caps


47


at its ends such that it resembles a rivet, is slightly longer than the combined heights of channels


40


and


50


, extends loosely between webs


41


and


51


, and is located slightly in front of hinge member


65


. Lower channel


50


can be pivoted downwardly, stem


46


being rocked from its vertical position, unto the bottom surfaces of webs


51


and


61


strike corresponding ones of caps


47


, which prevents further pivotal movement and which arrests the rocking movement of stem


46


, as shown in FIG


2


. The back ends of upper and lower blocks


45


and


55


abut stem


46


. In a preferred embodiment, the back ends of blocks


45


and


55


contact stem


46


, but they could also be closely spaced in front thereof A clasp C is pivotally mounted to the opposite end of clamp


30


from hinge member


65


. Clasp C, disclosed in U.S. Pat. No. 4,252,220, previously incorporated herein by reference, is comprised of a handle


89


and an elongate, essentially U-shaped wire loop


61


having terminal ends


62


and


62


′ that extend through orifices in the front end portion of handle


89


. Each terminal end


62


and


62


′ of wire loop


61


has a flattened end portion that prevents it from disengaging from upper channel


40


should clasp C be spread apart. Handle


89


has two lateral wings, only wing


88


being shown, that embrace the free end of lower channel


50


. Handle


89


is pivotally mounted on the free end of channel


50


by a pintle


83


to permit the pivoting of clasp C. A finger piece


90


at the rearward end of handle


89


permits a user to latch or unlatch clasp C. Clasp C is latched by swinging wire loop


61


into engagement with a retaining protuberance


96


located adjacent the forward edge of the end wall of upper channel


40


. Alternatively, loop


61


could engage a slot or channel in web


40


of upper channel


40


. The open position of clasp C and the spread apart position of clamp


5


are shown in dashed lines in FIG.


2


. By the rotation of handle


89


in a clockwise direction as shown in

FIG. 3

, clamp


5


tightly clamps channels


50


and


40


together and compresses and retains the hooks of one or more hangers which can be interposed between the protruding portions of resilient blocks


55


and


45


.




As mentioned above, the problem in the prior art has been the slippage of blocks


55


out of their respective channel


40


or


50


. In the present invention, this problem has been principally solved by a transverse member


58


which extends through the channel walls and block


55


located therebetween. Block slippage is further retaded by a vertical tab


57


that extends upwardly from web


51


, and by the reward ends of blocks


45


and


55


always being closely spaced from each other as a result of vertical stem


41


limiting the pivotal movement of channels


40


and


50


. Vertical tab


57


extends upwardly from the front portion of web


5


land can be produced, for example, by a stamping die. Vertical stem


41


which extends vertically in the rear portion of channel


50


prevents longitudinal movement of resilient block


55


within lower channel


50


, block


55


being wedged between vertical stem


41


and vertical tab


57


Transverse retaining member


58


, which in the present embodiment is a rivet, but could also be a pin or screw, is selectively located in a front portion of lower channel


50


and extends through a first outside channel wall


52


, a lower portion of lower block


55


, and a second channel wall


52


. Retaining member


58


prevents vertical movement of the front part of block


55


and retains block


55


in lower channel


50


.




A similar transverse retaining member or rivet


48


is selectively located in a mid portion of block


45


, extending through a first outside channel wall


52


, an upper portion of upper block


45


, and a second channel wall


52


. Retain member


48


retains upper block


45


in upper channel


40


. However, there is no corresponding vertical tab in upper channel


40


to tab


57


of lower channel


50


. A vertical tab is not needed in upper channel


40


to prevent longitudinal movement because there are essentially no longitudinal forces applied to upper block


45


, and retaining member


48


has been found to be sufficient, This is in contradisction to the longitudinal forces being applied to lower block


55


by the hangers being supported thereon.




It has also been found that only one transverse rivet


48


or


58


is required to effectively retain upper block


45


or lower block


55


within its corresponding channel


40


or


50


if that rivet is located in the forward portion of the corresponding block This is because vertical stem


46


limits the opening angle of clamp


5


and the corresponding amount of separation between blocks


45


and


55


. Thus, the rearward portions of each block


45


and


55


is closely spaced from each other, thereby preventing the rearward portions from disengaging from the corresponding channel. On the other hand, if transverse rivet


58


were located too far forward, then it would interfere with the operation of the pivoting of handle


89


of clasp C, or block


55


could split with use. Accordingly, the best longitudinal position that was found for rivet


58


was in the rear part of the forward most quarter portion of block


55


. The longitudinal positioning of trivet


48


,in upper block


45


was not so critical, but for ease of manufacture, its longitudinal position was chosen to be in a vertical alignment with rivet


57


. The best vertical position of each rivet was found to be as far down or up from the upper or lower surface of blocks


45


and


55


, respectively, as the corresponding rivet was from the forward most end of the block. This located the rivet in the respective lower or upper half of walls


42


and


52


, and in the respective lower or upper half of blocks


45


and


55


.




Thus, it has been found that rivet


48


is all that is necessary to prevent longitudinal movement and the elimination of a vertical tab in upper channel results in a cost savings and a saving in manufacturing time. In addition, a certain percentage of channels are damaged by the stamping process that is used to make vertical tab


57


, and this possibility of damaging upper channel


40


is eliminated.




Referring now to

FIG. 4

, a second embodiment of an improved jointed clamp


105


is depicted. Clamp


105


, as more fully described in recently issued U.S. Pat. No. 5,887,710, comprised of an upper clamp jaw

extend through the round orifices in both sides of clamp jaws


140


and


150


, respectively, and through a vertical slot (not shown) in blocks


145


and


155


. The vertical slot permits sight vertical movement of blocks


145


and


155


, while also preventing the full removal thereof from the channels of Clamp jaws


140


and


150


.




Referring now to

FIG. 5

, a third embodiment of an improved jointed clamp


205


is depicted. Clamp


205


, as more fully described in recently issued U.S. Pat. No. 5,590,765 is comprised of an upper clamp jaw


240


and a lower clamp jaw


250


connected adjacent their respective rear ends with a hinge pin


265


, and a latching device


280


that releasibly secures jaws


240


and


250


together, as depicted in FIG.

. Clamp jaws


240


and


250


are comprised of a channel having an inner space (not shown). A resilient block


245


is mounted in the inner space of clamp jaw


240


and a resilient block


255


is mounted in the inner space of clamp jaw


250


. Corresponding transverse retaining members


248


and


258


extend through round orifices in both sides of clamp jaws


140


and


150


and in blocks


145


and


155


, respectively. Members


248


and


258


retain blocks


245


and


255


within the channels of clamp jaws


240


and


250


, respectively.
