BACKGROUND OF THE INVENTION

[0004] 1. Field of the Invention

[0005] The present invention relates to an ergonomic handle and more particularly, to an ergonomic handle that includes a male side and a female side that nest together to form a single rigid form.

[0006] 2. Description of the Prior Art

[0007] People carry many types of carrying cases or bags in today's busy society. Such bags often include computer carrying cases, briefcases, luggage, etc. In today's hectic business world, people often have to travel, whether it be a short distance or a long distance, and require many different things in order to do their work or function at meetings or even give presentations. Since people use these bags to carry all types of materials, including computers, the bags or cases that people carry can become quite heavy. Thus, it is desirable to provide ergonomically appropriate features with today's carrying cases, bags, luggage, etc.

BRIEF SUMMARY OF THE INVENTION

[0008] Broadly the present invention provides an ergonomic handle that includes a male side and a female side. The male side nests in the female side to form a single, preferably rigid, form. The stiffness of the handle spreads the load of the case more evenly across all the fingers thereby helping to reduce fatigue.

[0009] More particularly, the present invention provides a handle for a carrying case. The handle includes a first portion that comprises an upper portion and a lower portion. The upper portion defines a receiving area and the lower portion defines a first carrying case engagement portion. The handle further includes a second portion that comprises an upper portion and a lower portion, with the upper portion defining a nesting part that nests within the receiving area when the handle is in use. The lower portion defines a second carrying case engagement portion. The nesting part pivots within the receiving area.

[0010] In accordance with one aspect of the present invention, the first and second carrying case portions each comprise a single elongated portion that is received by the carrying case.

[0011] In accordance with another aspect of the present invention, the first and second carrying case portions each comprise two individual parts that are received by the carrying case.

[0012] In accordance with yet another aspect of the present invention, the first portion may be separated from the second portion.

[0013] In accordance with a further aspect of the present invention, the nesting part is secured within the receiving area.

[0014] The present invention also provides a carrying case that comprises a body, at least two handle engagement portions and a handle. The handle includes a first portion that comprises an upper portion and a lower portion. The upper portion defines a receiving area and the lower portion defines a first carrying case engagement portion that engages at least one of the at least two handle engagement portions. The handle also includes a second portion that comprises an upper portion and a lower portion. The upper portion defines a nesting area that nests within the receiving area when the handle is in use. The lower portion defines a second carrying case engagement portion that engages at least one of the at least two handle engagement portions. The nesting part pivots within the receiving area.

[0015] The novel features that are characteristic of the present invention, as to organization and method of operation, together with further objects and advantages thereof will be better understood from the following description considered in connection with the accompanying drawings in which a preferred embodiment of the invention is illustrated by way of example. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the invention.

DESCRIPTION OF THE PREFERRED EXEMPLARY EMBODIMENTS

[0021] FIG. 1A illustrates a first portion or female component 11 for an ergonomic handle 10 in accordance with the present invention. As can be seen in the figures, an upper portion 12 of the female component includes a receiving area in the form of a groove or trench 13 defined therein. A bottom portion 14 is configured to be coupled to a bag or carrying case 30. The bottom portion may be coupled with straps or by being placed into a receiving portion 31 of the bag. Those skilled in the art will understand that other arrangements for coupling to a bag are also possible.

[0022] FIG. 1A also illustrates a second portion or male component 20 for the ergonomic handle in accordance with the present invention. As can be seen, an upper portion 21 of the male component is fairly “full” and preferably includes a rounded central portion 22, preferably at least the bottom of which is rounded. A bottom portion 23 of the male component includes a portion for attaching or coupling to bag or carrying case 30. The bottom portion may be coupled with straps or by being placed into a receiving portion 32 of the bag.

[0023] As may be seen in FIGS. 1B-4, the male component nests with the female component. As may be seen, upper portion 21 of the male component nests or rests within groove or trench 13 defined within the upper portion of the female component.

[0024] FIG. 1B provides a perspective view of a narrow orientation of the ergonomic handle. FIG. 2 illustrates the ergonomic handle in a wider orientation. This is achieved by the male upper portion pivoting within the female upper portion. By allowing the handle to pivot, the handle is able to accommodate a case width range of 1-5 inches at the location where the handle is coupled to the bag (i.e., the bag may be wider than 5 inches). This allows for a wide range of applications for the narrowest of laptop sleeves to much larger roller cases. Furthermore, the handle is well suited for expandable bags. Thus, an ergonomic handle in accordance with the present invention has a wide range of uses for various bags including, for example, computer carrying cases, briefcases, filecases, luggage, etc.

[0025] Preferably, the handle is made of a rigid material such as plastic, wood, metal, etc. A soft covering may be placed over some or all of the handle components to provide comfort to the user.

[0026] The handle may be configured such that the trench walls extend up and over the male upper portion. This would allow the male upper portion to be substantially secured within the female upper portion with a snap-fit type connection.

[0027] FIG. 4 illustrates an alternative embodiment where the handle portions are each coupled to carrying case 30 at two points 40a,b and 41a,b. Those skilled in the art will understand that there are other configurations that may be used to couple the carrying case to the handle.

[0028] Examples of dimensions for the handle include an overall length of 6.30 inches for the female portion and an overall length of 6.70 inches for the male portion. The handle has an overall height of 2.80 inches for the female portion and 3.25 inches for the male portion. The trench has a radius of curvature of 0.435 inches while the male upper portion has a diameter 0.87 inches. These dimensions are merely illustrative and those skilled in the art will realize that they may be changed depending upon the desired size of the handle, the size of the carrying case, the amount of spread capability desired for the handle, etc.

[0029] The above-described arrangements of apparatus and methods are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
