BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a roller grill separating device used in conjunction with a roller grill, which assists grill operators to separate uncooked products from cooked products and provide separate cooking areas for different products.
2. Discussion of the Related Art
In this era of fast food, individuals are increasingly dependent on quick service restaurants and convenience stores for a quick meal. Beginning in the 1960's and increasing in popularity ever since, the roller grill became an efficient way to cook and store hot dogs and other products to be made readily available to consumers without being labor intensive. With the advent of roller grills, these products could be prepared without the necessity of the store clerk flipping or rolling the grilled food by hand throughout the day. The development of the gas station/convenience store made this type of food even more widely available and popular.
With more opportunities to sell more products in these numerous establishments, the industry began offering additional hot dog types of products such as sausage, a 1⁄4 pound hot dog, spicy, mild, kielbasa, alternative meat hot dogs such as turkey, beef or soy, and others. All of these foods were still best prepared using the roller grill. Indeed, presently roller grills are still the leading hot dog cooker of choice for national convenience store chains, vending operations and cafeterias. These roller grills can be used on the front serving counter where customers serve themselves or on a back counter where a store employee takes an order from a customer and assembles and serves the food product such as a hot dog.
As noted above, the advantage of the roller grill is that the store operator does not need to continually monitor and roll the food products which frees the operator up for additional tasks. However, a problem arises in that the hot dogs can easily get ignored as the store clerk loses track of the time that each hot dog was originally placed on the grill. This problem becomes even worse with the practice of staggering hot dog placement on the grill. The employee must attempt to remember the time and flavor of each hot dog on the roller grill, and these grills are capable of cooking and holding a very large number of hot dogs. A poorly cooked hot dog can hurt or destroy a consumer's confidence in a particular eating establishment. Moreover, a hot dog which is undercooked or overcooked presents a serious health concern for the consumer, and the U.S. Department of Health has taken a strong interest in this issue.
Recent health and liability concerns have made it important to cook all foods to a predetermined temperature at a predetermined rate. This requirement by the U.S. Department of Health makes it critical that the operator keep track of how long each and every hot dog has been on the roller grill. In addition, with the many different flavors of hot dogs noted above, it is also important that the operator be able to identify the flavor of each and every hot dog on the grill.
There are products on the market for convenience stores and the like to merchandise the various hot dog flavors. These products are made of metal or plastic wire with either a plastic or metal sign area having two legs that extend through the rollers and a further perpendicular leg that passes between different rollers to support the sign. The problem with this type of grill sign is that they are not sanitary. Further, the signs take up too much space on the grill which could be used for cooking. In addition, the metal signs are hot to the touch, and therefore they cannot be moved easily and create a burning hazard to the operator. Despite the critical importance of monitoring cooking time, none of the then existing devices helped the operator keep track of cooking time or elapsed time.
These problems have been solved by the present inventor in U.S. Pat. Nos. 6,101,927 and 6,474,223. These patents illustrate a roller grill monitoring device having a clock face, a base which fits in between rollers of a grill roller, a stem for attaching the clock face to the base and a support structure attached to the stem disposed at a distance above the base so as to rest on the grill rollers. The device is inexpensive to make, is sanitary and made of a heat resistant material. The device further includes a removable signage area for sign clips that are used for identifying and marketing different types of food products such as hot dogs. Further, U.S. Pat. No. 6,474,223 illustrates the device that has openings and associated structure for accommodating at least one thermometer for monitoring the cooking temperature of the food product.
Although these inventions enabled grill operators to determine when the product is cooked, there are some problems left unsolved. In a roller grill that can cook many food products at one time, it is not always the case that one type of products are placed on the grill and removed from the grill all at once. Rather, the number of the products on the grill gradually decreases based on sale, and a grill operator keeps adding uncooked food on the grill accordingly. Therefore, cooked products and uncooked products are on the grill at the same time, and it is possible that uncooked products touch and contaminate cooked products. Without an effective grill separating device, it is hard for a grill operator to organize and manage the grill. It is also hard to identify which part is cooked and which part is uncooked, and which part is one type of products and which part is another. Also, hot dog items can move or “walk” from side to side and away from their respective sign identifier thus confusing customers and operators and making the grill look unorganized. A separator device keeps them from walking and better merchandises the grill.
There is presently no device that effectively separates cooked products from uncooked products or one kind of products from another. Moreover, there is no device that effectively separates cooking area on a grill without taking cooking space and at the same time displays marketing information and the type of food product for the operator and consumers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1A-F illustrate a roller grill separating device 100 comprising a clip 110, a center section 120, and upper sign clips 150 holding a sign 154. The clip 110 is in the shape of an arcuate clip-on member and is designed to fit onto a grill roller. Since the clip 110 is preferably made of FDA approved, heat resistant plastic, it is pliable enough to snap onto a grill roller. When correctly snapped onto place, as shown in FIG. 1F, inner circumference 112 of the clip 110 slides over a grill roller 160B. A precise inner diameter keeps roller scratching to a minimum. A projection 114 may be added to a front leg 116 to make the device 100 fit to thinner rollers. A flared portion of a rear leg 118 adds stability and keeps the device from rotating counter clockwise.
The center section 120 prevents rotation of the clip 110. In this position, the center section 120 keeps the device 100 in an upright position with ends 122, 124 resting on grill rollers 160A and 160C. The center section 120 has a rectangular cross bar hole 126, thermometer holes 130 and 132, and sign clips 134, 136 and 138. The center section 120 also has a crossover bar hole 140, a concavity section 142, a built-in separator bar accommodation slot 144, and two recessed portions 146 and 148 to accommodate a roundup grill. The center section 120 is very thin so that it does not take up room on the grill. This maximizes the area on the grill that can be used for cooking. The device 100 takes up virtually no space on the grill and adjacent hot dogs can be placed end to end very efficiently with no wasted space.
The roller grill separating device 100 also has upper sign clips 150 on the top of the center section 120. The upper sign clips 150, comprising a thinner clip 152 and a thicker clip 156, are to allow supplemental marketing point of sale items such as price tags, specials, promotions, ingredients, or new flavors to be inserted. It also allows quick response to competitive markets. Information containing materials can be attached to the separating device 100 with the sign clips 150. The thinner clip 152 has gripper teeth (non skid barbs) that can securely hold information containing materials. A clip-on sign holder like the sign clips 150 is much better than metal stands because it stays put and it does not get knocked over. Higher stands on grills that have slanted top rollers (stadium style) are not required.
As shown in FIGS. 1C and 1F, this invention discloses two thermometer holes 130 and 132 contained in the lower portion of the center section 120. The probe of a thermometer can be inserted into either one of the holes 130 and 132 so as to hold the thermometer in place. The thermometer can be of such type that the end inserted into the holes 130 and 132 can pass through the food product. Since the holes are wider than the diameter of the thermometer, the thermometer can rotate with the food product on the roller grill. This arrangement permits the thermometer to rest in one of the thermometer holes 130 and 132 so as to allow hands free and burn free food temperature monitoring. The thermometer holes 130 and 132 are for standard diameter products.
The sign clips 134, 136 and 138 are designed to accommodate rigid plastic 1⁄8′′ thick signs. The sign clips 134, 136 and 138 hold supplemental marketing point of sale items such as price tags, specials, promotions, ingredients, or new flavors.
The roller grill separating devices 100 can be used as free standing separators. For example, a plurality of separating devices 100 can be used to create a perpendicular wall on the grill by clipping the devices 100 onto every other roller in a straight line. In such case, there is a small chance that the separating devices 100 may move from side to side across the grill.
FIGS. 2A-E illustrate a roller grill separating device 200 comprising a clip 210, a center section 220, and upper sign clips 250. The clip 210 is in the shape of an arcuate clip-on member and is designed to fit onto a grill roller of a roundup type of grills. Since the clip 210 is preferably made of FDA approved, heat resistant plastic, it is pliable enough to snap onto a grill roller. When correctly snapped onto place, inner circumference 212 of the clip 210 slides over a grill roller. A precise inner diameter keeps roller scratching to a minimum.
The center section 220 prevents rotation of the clip 210. In this position, the center section 220 keeps the device 200 in an upright position with ends 222, 224 resting on grill rollers. The center section 220 has thermometer holes 230 and 232, and sign clips 234 and 236. The center section 220 also has a built-in separator bar accommodation slot 244, and two recessed portions 246 and 248. The center section 220 is very thin so that it does not take up room on the grill. This maximizes the area on the grill that can be used for cooking. The device 200 takes up virtually no space on the grill and adjacent hot dogs can be placed end to end very efficiently with no wasted space.
The roller grill separating device 200 also has upper sign clips 250 on the top of the center section 220. The upper sign clips 250, comprising thinner clips 252 and 254 and a thicker clip 256, are to allow supplemental marketing point of sale items such as price tags, specials, promotions, ingredients, or new flavors to be inserted. It also allows quick response to competitive markets. Information containing materials can be attached to the separating device 200 with the sign clips 250. The thinner clips 252 and 254 have gripper teeth (non skid barbs) that can securely hold information containing materials. A clip-on sign holder like the sign clips 250 is much better than metal stands because it stays put and it does not get knocked over. Higher stands on grills that have slanted top rollers (stadium style) are not required.
As shown in FIG. 2C, this invention discloses the two thermometer holes 230 and 232 contained in the lower portion of the center section 220. The probe of a thermometer can be inserted into either one of the holes 230 and 232 so as to hold the thermometer in place. The thermometer can be of such type that the end inserted into the holes 230 and 232 can pass through the food product. Since the holes are wider than the diameter of the thermometer, the thermometer can rotate with the food product on the roller grill. This arrangement permits the thermometer to rest in one of the thermometer holes 230 and 232 so as to allow hands free and burn free food temperature monitoring. The thermometer holes 230 and 232 are for standard diameter products.
The sign clips 234 and 236 are designed to accommodate rigid plastic 1⁄8′′ thick signs. The sign clips 234 and 236 hold supplemental marketing point of sale items such as price tags, specials, promotions, ingredients, or new flavors.
The roller grill separating devices 200 can be used as free standing separators. For example, a plurality of separating devices 200 can be used to create a perpendicular wall on the grill by clipping the devices 200 onto every other roller in a straight line. In such case, there is a small chance that the separating devices 200 may move from side to side across the grill.
FIG. 3 illustrates another embodiment according to the invention of another roller grill separating device 300. The roller grill separating device 300 comprises the roller grill separating device according to the first embodiment, a separator bar 370, and a crossover bar 380. The separator bar 370 is inserted into a built-in separator bar accommodation slot 344 and stands upright between upper sign clips 350 and a clip 310 of the roller grill separating device according to the first embodiment. The separator bar 370 keeps uncooked products from touching cooked products as well as creating neat grill appearance.
The roller grill separating device according to the first embodiment and the separator bar 370 may move side to side across a grill roller 360B as indicated by the two arrows in FIG. 3. To prevent the device from moving, a downwardly extending recessed portion 372 can be made at the front end of the separator bar 370 to secure the crossover bar 380, which is inserted into a crossover bar hole 340. The crossover bar 380 can be cut to be just fit between inner walls of a stationary grill body. Thus, the crossover bar 380 prevents the separating device according to the first embodiment and the separator bar 370 from moving side to side.
