The present invention relates to the field of utility gloves, for work, gardening and the like and, more particularly, to utility gloves for work, gardening and the like having elastomeric reinforcements for improved protection of the wearers' hands.
Utility gloves are used in areas such as gardening, construction or general work at a job site, production or garden facility or around one's home. These gloves usually contain a gripping portion that prevents items from slipping out of the user's hand, prevent injury to the user's skin such as cuts, scrapes and blisters, and provide a better grip when turning or grabbing objects. The gripping portion of the glove is usually applied to a knit nylon glove by dipping the nylon glove into an elastomeric material, such as natural or synthetic rubber, to apply an elastomeric gripping surface to the glove. This process increases the density of the glove and maintains a fabric portion which tends to absorb moisture and dirt and is hard to clean.
The purpose of the present invention is to create a utility glove with a seamless reinforcement in one or more zones most subject to abrasion. In addition to minimizing the seams, additional material or padding is provided in areas most subject to abrasion and/or impact, and this padding is preferably included without seams as well. In this regard, depending on the end usage envisioned, it is possible to adjust the amount of elastomeric material, including a natural or synthetic rubber, used in strategic areas to protect against impact and abrasion. Ultimately, the use of such padding provides the end user with a longer lasting, more comfortable glove. Additionally, the present invention includes the ability to provide different textures in the elastomeric material at strategic areas, to further provide one or more enhanced gripping surfaces.
It is therefore an object of the invention is to create a utility glove that is an improvement over typical dipped nylon knit utility gloves.
Another object of the invention is to provide additional durability and an ability to have varying palm thicknesses without having to increase the density of the knit utility glove.
A further object of the invention is to remove the reliance on fabric absorption of the elastomeric material to create density.
A still further object of the invention is to provide utility gloves with strategically placed padding and/or abrasion resistance zones as well as enhanced grip zones.
Yet a further object of the invention is to provide palm construction including an elastomeric material optionally without a knit backing, which typically absorbs excessive amounts of moisture and dirt. This allows for easier cleaning of the glove by simply being able to clean it off with a damp cloth as opposed to being laundered.
Another object of the invention is to create the maximum protection against abrasion in what typically are areas that require reinforcement, i.e., the index finger and thumb, as well as possibly the area between the index finger and thumb and the area directly below the base and crotch of each finger.
Still a further object of the invention is to provide abrasion and impact protection by raising the elastomeric material in the areas that are most likely to be subject to abrasion and impact, namely, the base of the thumb and the area of the palm directly below the fingers.
Another object of the invention is to create a molded component that can be altered to have varying elastomeric materials in different areas to provide for improved characteristics of the glove, and most particularly grip and flexibility. For example, softer elastomeric materials can be used for flexibility in areas less prone to wear and stronger, textured elastomeric materials can be used on in areas related to grip.
A further objective of the invention is to create a more natural feeling molded glove having a pre-curved concave palm portion, where the middle of the palm portion is set in from the edges of the palm portion to create an at least partially cupped shape, to minimize bunching when the wearer's hand closes. This pre-curved palm portion may also continue or extend to the fingers for a more natural shape of the hand at rest.
Still other objects and advantages of the invention will, in part, be obvious and will, in part, be apparent from the specification.
These and other objects are obtained through the utility glove of the present invention having a palm side including a three dimensional molded palm portion, the molded portion conforming substantially to the three dimensional contours of at least a portion of a hand, formed of an elastomeric material with a thumb portion and at least one finger portion and a back side of the glove comprising a fabric material, the molded palm portion formed in a pre-curved configuration. The molded palm portion may have one or more of thickened areas for abrasion resistance, padded areas for comfort, flex grooves for improved movement and textured grip areas for improved grip. The molded palm portion may be formed of different elastomeric materials to take advantage of the different characteristics of the particular materials.
It is also contemplated that the back side of the glove includes a molded portion, so as to form a guard over the user's knuckles or back of the hand that may be vulnerable to injury in some uses. The molded back may be independent from or formed integrally with the molded front side of the glove, and may be formed so that the molded portion extends 360° about the wearer's hand.
A molded portion of a utility glove may be formed by placing a piece of heat resistant fabric against a mold part formed in the shape of at least a portion of a hand, bringing a corresponding mold part into molding relation with the mold part in the shape of at least a portion of the hand and injecting an elastomeric material into the mold to form the molded palm portion.
It is anticipated that the mold part in the shape of at least a portion of the hand is formed in different sizes relative to the glove sizes of the potential users and the corresponding mold part includes one or more of one or more textured areas, one or more thickened areas, one or more padded areas and one or more flex grooves. Preferably, the heat resistant fabric is a knit hydrophilic material to improve absorbance of the elastomeric material.
The present invention will be better understood when considered in view of the attached drawings, in which like reference characters indicate like parts. The drawings, however, are presented merely to illustrate the preferred embodiment of the invention without limiting the invention in any manner whatsoever.
The molded palm portion 4 of the glove 2, or any molded portion of the glove, is preferably manufactured by using heat resistant knit hydrophilic fabric that can withstand heat of approximately 400 degrees Fahrenheit with a mold that comprises a mold part in the shape of at least a portion of a hand and a corresponding mold part. The heat resistant fabric is preferably in the form of a glove blank or can be cut in the shape of the outlined elastomeric material mold that forms the molded palm portion 4 of the glove 2, as shown in
Although any suitable knit hydrophilic heat resistant fabric can be used for the glove blank, it has been found that a nylon material is the most suitable for this invention as presently contemplated.
Significantly, the injection molding of the elastomeric material in the present invention permits the application of the elastomeric material on both sides of the glove 2, i.e., the palm side and the back side, while selectively leaving areas on the back of the glove 2 without an elastomeric material. This ensures breathability of the glove 2, where the open portions without an elastomeric material may have a mesh or other material covering the opening for user comfort.
For the three dimensional potion of the mold, namely the thumb and index finger in the embodiment of
In either event, the molded elastomeric material is intended to adhere to all areas of the fabric, including the cap for covering the entire tip of the thumb and index finger or fingers, as well as the majority of the circumference of the thumb and fingers to be covered, that is at least 50% of the circumference of the user's thumb and fingers, as desired.
Optionally, a thin lining material can be inserted into the flat side of the mold prior to shooting the elastomeric material, so that whatever portion of the mold that would be in contact with the palm, thumb and fingers of the user would be lined. Fabric could then be stitched onto the contour of each finger and reinforcement area of the glove 2, if desired.
The final bonded component forming the molded palm portion 4 is then attached to the balance of the glove 2. Preferably, the fabric that is visible on the back of the molded fingers, including the back of the thumb and the back of the index finger in
In the embodiment of
With respect to the elastomeric materials used in the formation of the molded palm portion 4, different compositions of elastomeric material can be used in the formation of the molded palm portion 4 or parts thereof. For example, an elastomeric material that is less slippery when wet may be used along the area between the thumb and index finger, allowing the glove to be more versatile in wet conditions. Moreover, if abrasion resistance is of particular importance in an area of the molded palm portion, a denser material can be used in that area. Similarly, where impact resistance is of particular importance in an area, such as a padded area, a less dense elastomeric material may be preferred. The proper applications of such variations will be apparent to one skilled in the art.
Notwithstanding, it has been found that thermoplastic vulcanite (TPV) and thermoplastic rubber (TPR) are preferred materials for forming and serving as the elastomeric material used in the glove 2 of the present invention.
In the embodiments shown in
In some embodiments, such as in
The palm portion 4′ is preferably pre-curved in a concave configuration to minimize bunching when the wearer's hand closes. The molded palm portion 4 also preferably contains embossed gripping details 6, such as textured loops, to increase gripping and enhance the protection of the user. The back portion of the glove 2 preferably includes a closure element, shown in the form of a stretchable material 18 rather than a wrist strap 16, to provide a tight and comfortable fit while permitting easy insertion and removal of the wearer's hand.
Of course, the molded palm portion 4 of the glove 2 of
In the preferred embodiment of
The molded second areas 22 of the embodiment of
The molded third areas 24 of the embodiment of
Of course, in addition to or alternatively, the elastomeric material in the various areas 20, 22 and 24 may have different physical characteristics. These include differences in density, tackiness, flexibility, etc.
Also as shown in
Additionally, the molded portion of the glove 2 of
Moreover, as will be apparent to those skilled in the art, the glove 2 of the present invention can be designed with different combinations of the components described above. For example, the glove 2 of
