THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE

PERFORMED. FIELD OF THE INVENTION:

This invention relates to the field of mechanical engineering.

Particularly, this invention relates to exercise equipment.

Specifically, this invention relates to an exercise equipment assembly for jaw muscles and neck muscles.

BACKGROUND OF INVENTION

There are numerous exercise devices and equipment for muscles of arms, shoulder, back, and legs. However, there are very few equipment or devices for exercising muscles in face, jaw, and neck.

For face and neck muscles’ workout, different exercises include face yoga, physiotherapeutic exercise, different facial movement and stretches. Some equipment for exercise includes chewing ball and neckline slimmer. For athletes, who need heavy exercise, there are very limited options. Some such equipment comprise a head strap.

Exercise of muscles located in face, jaw, and neck have mainly three types of uses:

1] Therapeutic Use;

2] Fitness use / Cosmetic use; and

3] Athletic use / sport use.

1] Therapeutic use: Various medical conditions require systematic exercise of muscles of mastication, facial muscles and neck muscle. E.g. oral submucous fibrosis, TMJ dysfunction, post-surgical exercise, physiotherapeutic exercise, orofacial myofunctional therapy and the like conditions require respective specific muscle exercise or symmetric movement of jaw and neck.

2] Cosmetic use: For youthful appearance, sharp jawline, toned muscles, exercise of that particular muscle, face muscles, muscles of mastication, neck is required. It makes tightening of muscle / face, less loose skin, reduces wrinkles, less headache, less eye strain, and reduces double chin. Similar to other muscles in legs and arms, when a person exercises those muscles, it improves strength and appearance and improves fitness and function.

3] Athletic use / Sport use: High end sport e.g. boxing, MMA fighting, combat sport or fighting sport requires high strength of muscles of face, muscles of mastication, jaw and neck to perform best in that sport. Concussion can occur with a punch or kick on jaw. Strong punch or kick on the jaw and face can be lethal or can do permanent disability. Therefore, strong muscles of jaw and neck help in resisting injury and taking punch on face or chin without being knocked down. This requires heavy exercise e.g., using neck or head strap weight is attached, chewing ball, neck line slimmer, and the like.

For above uses there is needed a device or apparatus or equipment assembly which is more targeted and help in exercise of light and heavy nature in order to strengthen face, jaw and neck muscles.

According to this invention there is provided an intraoral tray and an extraoral tray connected together with a fastening mechanism. These two trays hold mandible / lower jaw firmly and provide hooks by which a weight machine can be attached for weight lifting and exercise of jaw and neck muscles.

The intraoral tray and the extraoral tray is extended by a handle element for providing space for attachment of fastening mechanism, to fasten both trays [17, 19] to lower jaw or mandible. For illustrative purpose, few types of handle element are shown in Figures but there can be multiple types of handle design and arrangements that are possible. E.g. Fox plane type, round straight bar attaching horizontal plane and vertical plane, semi-circular type handle, U-shaped type, flat plate type, etc.

Similarly, two fastening mechanism, are shown; nut and bolt type in Figures of exercise equipment of the current invention. However, it is to be understood that there can be various types of fastening mechanisms possible to attach intraoral tray and extraoral tray, for example, clamp type, and the like.

Figure 1 shows extraoral tray [19].

In at least an embodiment, the exercise equipment assembly of this invention comprises at least an extraoral tray [19]. The extraoral tray [19] is a two pronged assembly, each prong being an elongate channel. The pronged channel comprises a chin end and two mandibular angle ends. The chin end [78] is where the prongs of the extraoral tray join each other. The mandibular angle ends [76] are where the prongs of the extraoral tray end. The pronged channel comprises an operative right flange [86a] and an operative left flange [86b]. Typically, the channels are contoured to fit with the jawline extending from the chin, running along the length of the mandible, and ending at a location spaced apart from the ear on the jawline. In other words, the extraoral tray [19] holds a lower jaw by providing external upward grip on lower jaw or mandible of a user using this exercise equipment assembly.

Typically, the channels are concave channels, the concavity being contoured to align with a jawline. The concavity may be custom-defined per user, and therefore, the channel and the corresponding extraoral tray [19] can be customised per user dimensions. In a preferred embodiment, the channel of the extraoral tray [19] may be lined with a cushioning element [36].

In at least another embodiment of the extraoral tray, the prongs are flat. These flat prongs are sloping or tilted towards neck so that it will not interfere with jaw and neck stretch. Flat surface of pronged channels gives more surface area to hold or support inferior border of mandible or base of mandible as shown in Figure 7.

For illustrative purposes, extraoral tray [19] with curved channel prongs [86a and 86b] are shown in Figure 1 and Figure 4 and extraoral tray [19], with flat prongs, is shown in Figure 7.

The extraoral tray provides grip on the mandible from angle of mandible to chin region, symmetrically. Posterior end [76] of the extraoral tray [19] is aligned with angle of mandible. Inner surface of extraoral tray is concave [44] to provide a better fit along base of mandible or inferior border of mandible. Therefore, outer surface of two prongs [86a and 86b] are convex [74] in shape.

Typically, in its aligned position with respect to a user’s face, lower border [80] of the extraoral tray [19] is aligned with inferior border of mandible and upper border [82] of the extraoral tray [19] is directed towards cheek region. The area where the pronged channels mate provides a chin resting area [78].

In the extraoral tray [19], corner of flanges [76], lower border of flanges [80], and the chin resting area [78] where both flanges [86a, 86b] join each other are designed in such a way that it will not obstruct jaw and neck muscle stretches during exercise. A cushioning element [36] is provided on metal frame [38] to provide grip and comfort on a base of mandible or inferior border of mandible or body of mandible and chin region or mental protuberance when the equipment is used.

In at least an embodiment, the extraoral tray [19] comprises a frame or a body made of metal or high strength rigid material [38], the extraoral tray [19] extends to provide a handle element [21]. Typically, the handle element [21] is a horizontal element with a first hole [13] extending upward into a vertical element [58] with a second hole [84] followed by a third hole [20]. The first hole is configured to receive a first fastening mechanism. The second hole is configured to receive a second fastening mechanism. This fastening mechanism is used when the extraoral tray [19] aligns with an intraoral tray [17]. The horizontal element [21] translates into the vertical element [58], the translation being caused by a torsioned element [54].

In at least an embodiment, a weight hanging means [20] is advantageously provided to attach weights or to attach equipment, of this invention, to a weight lifting machine to increase resistance. Typically, this may be a loop. Typically, this may be a hole on a tray. Typically, loops [20] can be given on outer surface, at end portion and chin resting portion of an extraoral tray [19].

In at least an embodiment, a round straight bar joins horizontal element [21] and upwardly tilted vertical element [58]. Figure 2 shows intraoral tray [17]. Figure 2 is shown by keeping the operative lower surface upwardly facing so that the occlusal facing downward surface [34] that is surface facing lower mandibular teeth of intraoral tray [17] can be seen.

In at least an embodiment, the exercise equipment assembly of this invention comprises at least an intraoral tray [17].

The intraoral tray [17] is a two pronged assembly, each prong being an elongate channel. The pronged channel comprises a mandibular anterior teeth end and a mandibular posterior teeth end. The mandibular anterior teeth end is where the prongs [81a, 81b] of the intraoral tray join each other. The mandibular posterior teeth ends are where the prongs of the intraoral tray end. Typically, the channels are contoured to fit with the mandibular teeth, especially posterior teeth extending from the lower lip, running along the length of the mandibular teeth arch alongside buccal mucosa, and ending at a location near lower second molar tooth inside the oral cavity, resting on the lower posterior teeth. In other words, the intraoral tray [17] holds a lower jaw by providing intraoral downward grip on lower jaw or mandible of a user using this exercise equipment assembly.

Typically, the channels are concave channels, the concavity being contoured to align with the teeth on which it rests. Inner surface [34] of intra oral tray is concave and is placed on occlusal surface of teeth. The concavity may be custom-defined per user, and therefore, the channel and the corresponding intraoral tray [17] can be customised per user dimensions. In a preferred embodiment, the channel of the intraoral tray [17] may be lined with a cushioning element [30]. Preferably, the intraoral tray [17] is fit on occlusal surface of lower teeth, especially posterior teeth. As jaw size and occlusal shape are different for different individuals, therefore, generally, there are 5 different sizes of intraoral trays and extraoral trays that can be defined to fit the general population demographic. A user can select an intraoral tray [17] and extra oral tray [19] equipment according to its fitting on lower teeth and its fitting on inferior border of mandible, respectively.

Preferably, operative posterior end [96] of intraoral tray [17] should be aligned with lower second molar or at least first molar should be covered by posterior end [96] of intraoral tray [17] for proper grip and weight distribution. If there is any missing tooth of user, then missing teeth should be replaced first in dental office or a customized special tray has to be made or both to maintain balanced weight. The distance between inner border [98], or medial edges [98], of the prongs of the intraoral tray [17], and outer border [97], or lateral edges [97], of the intraoral tray [17] is such that it covers occlusal surface of lower posterior teeth.

The inner border [98] is contoured such that it does not interfere, obstruct or injure tongue and the outer border [97] is contoured such that it does not obstruct or injure buccal mucosa, cheeks, and gums.

In at least an embodiment, the intraoral tray [17] extends to provide a handle element [50]. Typically, the handle element [50] of intra oral tray [17] extends curvilinearly operatively upward apart from the nose extending out of the mouth, since Figure 2 is shown with downside up view of intraoral tray [17] wherein handle element [50] is shown curving downward. It then extends into an operative horizontal element [52] comprising a fourth hole [92] configured to receive a first fastening mechanism [18] and [10] when aligned with first hole of extraoral tray [19]. This horizontal element [52] further extends downward into a torsioned element [15] which then translates into a vertical element [94] with a fifth hole [99] for insertion of a second fastening mechanism. This second fastening mechanism [68 and 14] is used when second hole [84] in the extraoral tray [19] aligns with a fifth hole [99] in the intraoral tray [17] during wearing of equipment by user [66]. A first fastening mechanism [18 and 10] is used when user wear intraoral and extraoral tray and first hole [13] of extraoral tray [19] is aligned with forth hole [92] in intraoral tray [17] as shown in Figure 6.

In at least an embodiment, a horizontal element [52] tilted downward and extended by round bar into a vertical element [94]

In at least an embodiment, a weight hanging means [20] is advantageously provided to attach weights or to attach the equipment to a weight lifting machine to increase resistance. Typically, this may be a loop. Alternatively, this may be a hole.

Back side, of each of the prongs [81a] and [81b], is convex in shape [25] with cushioning element [30], providing surface for chewing or holding on to upper teeth as shown in Figure 4.

Portion of intra oral tray which is inside mouth is covered with cushion element [30] which has corrugated lining so that it would not slip and damage teeth or intra oral hard or soft tissue. Core or frame of intraoral tray is made up of metal or high strength rigid material [32] for strength. Two prongs [81a] and [81b] of intraoral tray meet in a V-shaped manner [40]. Intraoral tray has curved occlusal teeth facing surface arch between posterior end [96] and horizontal surface [52], as seen in Figure 2. This V-shaped joining and curved surface arch of intraoral tray enables it to remain in contact with posterior teeth.

Figure 3 shows another embodiment of the intraoral tray [17].

While the intraoral tray [17], of Figure 2, comprises a curved handle [50], curved lower occlusal teeth facing surface arch between posterior end [96] and horizontal surface [52] and V-shaped joining of two prongs [40], the intraoral tray of Figure 3 has U-shaped joining of two prongs [4] and a straight handle element [6] extending out of the mouth of a user, when the equipment is fit to a user.

In a preferred embodiment, the intraoral tray [17], as per Figure 3, has a U-shaped joining [4] of two prongs [83a] and [83b] which should be fit on lower set of teeth during working of the equipment of this invention. In order to provide maximum contact of intraoral tray [17] on lower posterior teeth [42], a relatively thicker cushion [30] is given on posterior side of prongs [83a] and [83b] of the intraoral tray [17] and the anterior side [4] of the intraoral tray has relatively thinner cushion [2], thereby providing minimum contact with anterior teeth. Preferably, the posterior end [96] of the intraoral tray [17] should be in contact with lower second molar teeth or at least the lower first molar should be covered. Core of the intraoral tray or frame or body [32] of intraoral tray is made up of metal or high strength material.

Inside of tray or surface of tray facing occlusal surface of lower teeth [34] has concave and corrugated surface for better grip and for holding teeth. Back side of the tray or surface of tray facing occlusal surface of upper teeth is flat [8] in shape so as to provide bite surface for upper teeth if required during exercise. This is shown in Figure 7

Inner border [98] and outer border [97] of prongs [83a, 83b] of intraoral tray [17] is rounded. Similarly, all edges and corners are rounded and does not obstruct or hurt tongue, buccal mucosa, and cheek during exercise when the equipment of this invention is fit into position.

In at least an embodiment, the intraoral tray [17], as shown in Figure 3, extends to provide a handle element [6]. Typically, the handle element [6] of intra oral tray [17] extends operatively straight [6] to come out of mouth and lips then handle element [6] extends turns upward [9] but apart from the nose extending out. Since Figure 3 is shown with downside up view of intraoral tray [17], handle element extension [9] is shown turned downward. It then extends into an operative horizontal element [52] comprising a fourth hole [92] configured to receive a first fastening mechanism [18 and 10] when aligned with first hole of extraoral tray [19], as shown in figure 6. This horizontal element [52] further extends downward into a torsioned element [15] which then translates into a vertical element [94] with a fifth hole [99] for insertion of a second fastening mechanism [68 and 14]. Sixth hole or loop [20] can be given for attaching to weight lifting machine when equipment is used by user [66], as shown in Figure 6.

In at least an embodiment, the handle element [6] is tilted upward and extends by a straight bar into a horizontal element [52], said horizontal element [52] tilted downward and extend by round bar into a vertical element [94]. Figure 4 illustrates lateral cross section of mandible wearing the equipment of this invention.

In accordance with an embodiment of this invention there is provided an extraoral tray [19] and intraoral tray [17]. The extraoral tray [19] has concave inner surface [44] facing towards base of mandible [46] this concave inner surface [44] provides space to retain inferior border / base of mandible [46] firmly. The extraoral tray has a convex outer surface [74]. The extraoral tray [19] runs along inferior border of mandible [46] in order to hold it firmly from angle of mandible to chin region of mandible along its length. The extraoral tray [19] fits a lower jaw’s inferior border [46] from midline of inferior border [46] of mandible towards cheek region [11] in its width in such a way that the extraoral tray [19] does not interfere with jaw and neck muscles [12] during jaw and neck exercise. The prongs [86a] and [86b] of extraoral tray [19] is slightly concave [44] in its shape so as to fit mandibular base [46] properly. It extends from centre of base of mandible or inferior border of mandible [46] towards cheek [11] region in its width. Extra oral tray [19] has outer shell with cushioning element [36] so that when it comes in contact with skin [11] and mandible [46], it does not hurt it. Its core is made up with rigid material or metal [38] which is slightly concave. This core [38] provides strength to the extraoral tray [19]. Superior border [16] of mandible [56] is covered with alveolar bone and teeth [42] placed in it. Lower border [80], of prongs [86a], [86b] of extraoral tray [19], is aligned with inferior border [46], or base, of mandible and upper border [82], of prongs [86a], [86b] of extraoral tray [19], is directed towards cheek region [11].

The intraoral tray [17] has a concave [34] inner surface facing towards the teeth [42]. Further, it has outer [30] soft cover (cushioning element) which provides cushioning effect for the teeth [42]. It is concave in shape [34] in order to cover occlusal surface of teeth [42]. The inner core of the intraoral tray [17] is made with rigid material or metal [32] to provide strength and frame.

This intraoral tray [17] and extraoral tray [19], when fit tightly, hold the mandible [56] firmly, when weight is attached to these trays. This weight goes to mandible [56], face, jaw, and neck muscles [12]. Inner border [98], of each of the prongs [81a, 81b] of intraoral tray [17], is rounded so as to do not injure tongue [87]. Outer border [97], of each of the prongs [81a, 81b] of intraoral tray [17], is rounded so as to not injure cheek, buccal mucosa [28], and jaw muscle [48]. Back side, of each of the prongs [81a], [81b] of intraoral tray[17], that is surface facing occlusal surface of upper teeth is convex [25] for providing soft or cushioned chewing surface to upper posterior teeth when upper and lower jaw closes as per need of user. Back side, of intraoral tray that is surface facing occlusal surface of upper teeth, can be of variety of shapes. E.g. it can be flat [8] as shown in Figure 2 or concave or customised according to upper teeth of a user, thereby providing surface for upper teeth of a user for chewing or holding tray, if needed.

Figure 5 shows intraoral tray [17] and extraoral tray [19], both with additional handle, placed in position with respect to lower jaw and tightened with a first fastening mechanism [18 and 10].

The extraoral tray [19] is kept in position with base of mandible or inferior border of the mandible. Posterior end [76] of extraoral tray [19] is coincided with angle of mandible. The extraoral tray [19] has a straight handle [21] and an additional handle [22] is given so that a fastening mechanism [18 and 10] can go through it to provide better stability of tray. The extraoral tray [19] is provided with hooks [20] for attaching to a weight lifting machine. The prongs, of extra oral tray, can be curved or flat depending upon requirement of a user [66].

The intraoral tray [17] is provided with a straight handle [6] and an additional handle [72]. These handles [6] and [72] of intraoral tray [17] have holes [92], [26] and handles [21], [22] of extraoral tray have holes [13], [24] respectively for insertion of fastening mechanisms [18], [10] for tightening the intraoral tray [17] and the extraoral tray [19] over lower jaw or mandible. These trays can be selected by a person according to their individual jaw size.

While Figure 5 shows an additional handle [22] and [72] to extraoral tray [19] and intraoral tray [17], respectively, attached to it and only one fastening mechanism [18, 10] and is provided to fix it, Figure 6 shows a single handle to both trays and two fastening mechanisms [18, 10, 68, and 14] to tighten upper and lower tray over lower jaw.

Figure 6 shows intraoral tray [17] and extraoral tray [19] fixed on lower jaw [70] for pulling weights.

The extraoral tray [19] is placed or aligned with base of mandible or inferior border of mandible of lower jaw [70]. Posterior end [76], of extraoral tray [19], coincides with angle of mandible. The extraoral tray has a straight handle [21] for providing holes [13] for nut insertion [18]. This straight handle [21] turns in an operative upward direction and then twists [54] to become vertical in plane [58] providing hole(s) [84] for insertion of nut [68] and tightened with bolt [14]. This vertical plane hole coincides with hole [99] on vertical plane [94] of the intraoral tray [17]. This vertical plane is provided with U-shaped loop or hole [20] for attaching to a weight machine. This weight machine has extended wire [60] to join U-Shape loop or hole [20] with hook [62] attached to its wire [60]

A user [66] has to select an intraoral tray [17] and an extra oral tray [19] according to its fit on lower jaw [70]. The fit is to be checked with occlusal coverage of the intraoral tray [17] and base of mandible on the extraoral tray [19].

The intraoral tray [17] is selected from different sizes and shapes according to its fit on occlusal surface of individual [66]. Its correct size selection is important so as to achieve correct functioning of the instrument with correct distribution of weight on muscles of jaw and neck.

The intraoral tray [17] has a curved upward handle [50]. This curved handle [50] is tilted to become horizontal [52] or roughly parallel to occlusal plane of lower teeth to provide hole [92] for insertion of nut [18], and bolt [10] is tightened over nut [18]. This horizontal plane [52] of the handle is extended and turned downward. Further, this extended handle is twisted [15] in its plane to become vertical [94] for providing horizontal insertion of nut [68], through hole [99] and bolt [14] is tightened over nut [68]. The U-shaped loop or hole [20] is provided on a different part of the extraoral tray [19] or the intraoral tray [17] for providing pressure on different muscles when it is attached to a weight machine. Nut [18] and bolt [10], cumulatively, is referred as first fastening mechanism whereas nut [68] and bolt [14], cumulatively, is referred as second fastening mechanism.

Figure 7 illustrates lateral cross section of mandible wearing the equipment of this invention. One of the differences between equipment of Figure 4 and equipment of Figure 7 is that, in Figure 4, lateral cross section of extraoral tray shows concave inner surface and convex outer surface of two prongs [86a], [86b] of extraoral tray supporting mandible whereas, in Figure 7, lateral cross section of extraoral tray [19] shows flat inner and outer surface of two prongs [23a], [23b] of extraoral tray supporting mandible.

In Figure 7, inferior border of mandible [46] or base of mandible is coincided with tilted [93] and flat inner surface [88] of prongs [23 a], [23b] of extraoral tray between lower [89] and upper [91] border of extraoral tray whereas, in figure 4, inferior border of mandible [46] or base of mandible is coincided with lower border [80] of extraoral tray.

Tilted [93] angle helps in free movement of muscles of jaw and neck while flat surface [88] helps in providing larger surface area for base of mandible [46] to fit.

Intraoral tray in Figure 4 has convex back surface [25] of tray whereas, in Figure 7, intraoral tray has flat back surface [8] of each of the prongs [83a, 83b] of the tray.

In accordance with another embodiment of this invention, there is provided an extraoral tray [19] and an intraoral tray [17]. The extra oral tray [19] has a flat inner surface [88] facing towards base of mandible [46]. This flat inner surface [88] provides more space to retain inferior border / base of mandible [46] firmly. This flat inner surface is tilted [93] in inward direction towards neck in a sloping manner. This type of slope provides more surface area to support inferior border of mandible when the extraoral tray [19] runs along inferior border of mandible [46] in order to hold it firmly from angle of mandible to chin region of mandible along its length. Upper border [91] and lower border [89] of two prongs [23a], [23b] of extraoral tray are rounded so that it would not injure or hurt skin, muscle, or bone.

The long axis [93] passing through upper border [91] and lower border [89] of prongs of extra oral tray is tilted towards neck [12] in such a way that it would not interfere with jaw and neck muscle [12] stretch during exercise. The extraoral tray [19] is flat in its shape; so, slight difference between size and shape of mandible of different user does not pose difficulty in its proper fit. Flat surface [88] of prongs [23a], [23b] of extraoral tray fit mandibular base [46] properly between different users. Extraoral tray has outer shell with cushioning element [36] so that when it comes in contact with cheek [11], skin, and mandible [46], it does not cause any hurt. Its core [38] is made up with metal or strong rigid material which is flat. This core [38] provides strength to the extraoral tray [19]. Superior border [16] of mandible [56] is covered with alveolar bone and teeth [42] placed in it. Lower border [89] of extra oral tray[19] is directed towards neck [12], flat inner surface [88] is aligned with inferior border [46] or base of mandible and upper border [91] of extraoral tray [19] is directed towards cheek region[l l], outer surface is also flat [90].

The intraoral tray [17] has a concave [34] inner surface facing towards the teeth [42]. Further, it has outer [30] soft cover [cushioning] element which provides cushioning effect for the teeth [42]. It is concave in shape [34] in order to cover occlusal surface of teeth [42]. The inner core of the intraoral tray [17] is made with rigid material or metal [32] to provide strength and frame.

The intraoral tray [17] and extraoral tray [19], when fit tightly, hold the mandible [56] firmly when weight is attached to these trays. This weight goes to mandible [56], face, jaw, and neck muscles. Inner border, [98] of each of the prongs [83a, 83b] of intraoral tray [17], is rounded so as to not injure tongue [87]. Outer border [97], of each of the prongs [83a, 83b] of intraoral tray [17], is rounded so as to not injure cheek or buccal mucosa [28]. Back side[8], of each of the prongs [83a , 83b] of intra oral tray [17] that is surface facing occlusal surface of upper teeth, is flat for providing more soft or cushioned chewing surface area to upper teeth when upper and lower jaw closes as per need of user. Back side of intraoral tray[17] that is surface facing occlusal surface of upper teeth can be of a variety of shapes; for example flat [8], convex [25] or it can be customised according upper teeth of a user, thereby providing surface to upper teeth of a user for chewing or holding tray if needed by user.
