FIELD OF THE INVENTION

The present invention is directed generally to an exercise and rehabilitation device. More specifically, the present invention is directed to a unique muscle resistance training and physical rehabilitation device for strengthening various muscles of the human body, while improving flexibility of the cervical spine, providing relief of muscle pain and discomfort, particularly in the neck area, and improving overall physical health.

BACKGROUND OF THE INVENTION

Both resistance strength training and isometric and isotonic exercises for the human neck and the upper body musculature are the safest and most effective way to strengthen the neck, shoulders, chest and back and to relieve neck pain. Experts in the field of human physiology typically recommend that clients use their own hands or utilize rubber and elastic straps to provide resistance during isometric, isotonic, extension and strength exercises for the neck and the upper body. The problem with these recommendations is that they often put the clients into awkward or dangerous physical positions. Current prescribed methods are cumbersome and complicated and limited in functionality. There are additional dangers with the often prescribed or utilized rubber stretch bands. These elastic bands are typically wrapped about the head and may break or become untied, causing the strap to snap back at the user causing injury. With commonly prescribed methods of elastic band exercises being cumbersome and difficult, clients tend to discontinue recommended neck and upper body rehabilitation and exercise programs before the user really gets the benefit of the intended isometric and isotonic neck and upper body exercise routines. There are also significant limitations with the trajectory of elastic band exercises being limited by points of the band's connectivity, be it a doorknob or door frame mount, where the elastic band is in a fixed position thus limited in its range of usefulness.

Alternatively, some experts recommend the use of a wall and a ball for isometric and isotonic neck exercises. Clients have been instructed to use a ball between the head and a wall. This positioning of a ball is very uncomfortable for the client as the ball can move around and even fall to the ground causing the client's head to collide with force against the wall as the client's full body weight is directed to the wall.

Prior art neck exercise devices such as neck head harnesses and four-way neck machines promote shearing forces since the cervical spine is repeatedly flexed and extended under a fixed, measured weighted resistance which can lead to cervical neck and muscle damage, particularly if the device is used improperly or under excessive load. Furthermore, such devices are expensive and otherwise quite complicated and relatively difficult to use properly.

One particular prior art neck exercise device employs a neck head harness with weights, attached through cables, as opposed to simply using one's hands. Such machines are flawed in that they have been found to often cause a number of associated neck disk herniations. A safer, more effective, and more functional device would have a continuously variable resistance and variable directional ability where infinitely variable plane of resistance and trajectories could be achieved.

In general, conventional resistance training typically requires several very expensive pieces of equipment that take up a significant amount of space and are not easily stored. Also, strength and resistance training equipment is often not easily transportable.

SUMMARY OF THE INVENTION

The present invention provides for an improved, easy to use and novel device for facilitating both isometric and isotonic resistance exercises while also offering a method for application of cervical traction.

Prior art resistance training and rehab devices provide limited functionality, are relatively expensive, are not portable and are generally impractical.

The device of the present invention offers a Positive and Negative XYZ AXIS resistance variation. The device offers strength training and range of motion exercises to an otherwise inaccessible method of neck musculature training and rehabilitation.

The device of the present invention may be used in a sitting, lying down or standing position.

An embodiment of the present invention is lightweight and may be broken down into sections, thereby allowing for the device to be easily stored and transported in a gym bag and the like.

An objective of the present invention is also to provide a neck exercise, strengthening and rehabilitation aid for the cervical spine and surrounding musculature.

Another objective of the present invention is to provide a versatile, lightweight and easily transportable resistance exercise and rehab device.

A further objective of the present invention is to provide a means of achieving effective upper body exercise for the elderly or other individuals who may have physical limitations, whereby gains in strength, range of motion and endurance may be achieved by using a lightweight, versatile exercise device.

An embodiment of the present invention comprises a flexible strap that fits around the user's head in the manner of a headband, a rigid outer ring, and a webbing of elastomeric cords that are threaded through evenly spaced holes in the flexible headband strap and that operably join the headband strap to the outer ring.

An embodiment of the present invention further may include an adjustment mechanism allowing for the adjustment of the tightness of fit of the headband strap to the user's head.

An embodiment of the present invention further may include elastomeric cords which may be adjusted to provide for variability in the resistance level provided by the device. As the tension of the elastomeric cords is adjusted, the resistance force created by the device may accordingly be increased or reduced. Higher resistance or heavier elastomeric cord may be utilized for a more intense, higher resistance training session. The outer ring may be reinforced with a rigid continuous ring and not collapsable.

In view of the above, it is an object of the present invention to overcome the shortfalls in the related art by presenting an improved, broad-spectrum neck and upper body rehabilitation and exercise training device which facilitates either or both isotonic and isometric methods of exercise.

DETAILED DESCRIPTION

The following detailed description is merely exemplary in nature and is not intended to and should not be interpreted to limit the embodiments described herein. Although particular embodiments are described, those embodiments are merely exemplary implementations of the present invention. The following descriptions and illustrations herein should be considered illustrative in nature, and thus, not in any way limiting the scope of the present invention. One skilled in the art will recognize other embodiments are possible and all such embodiments are intended to fall within the scope of the present disclosure. While the preferred embodiments are described with reference to the above drawings, there is no intent to limit the disclosure to the embodiments shown in the drawings or disclosed herein. Rather, the intent is to include all alternatives, modifications and equivalents that embody the spirit and scope of the disclosure.

It is also to be understood that the disclosure uses terminology for the purpose of describing particular embodiments and such terminology is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used in this disclosure have the same meaning as commonly understood by one of ordinary skill in the art to which is applicable to this disclosure.

As will be apparent to those of skill in the art upon reading this disclosure, each of the embodiments described and illustrated herein has discrete components and features which may be readily separated or combined with features of any of the other possible embodiments without departing from the spirit and scope of the present disclosure.

Musculoskeletal disorders are one of the most common causes of physical disability. One of the most common musculoskeletal disorders is neck pain. Nearly a quarter of the population at any given time may be plagued with some form of neck pain. Diagnosis and treatment of neck pain are relatively misunderstood and, therefore, treating neck pain is a challenging endeavor. Managing and treating neck pain has proven to be enhanced by the use of devices that allow for strengthening of the neck muscles and for increasing rotational strength and mobility of the neck.

The present invention provides a novel device and method for applying resistance to various muscles of the body, allowing for strengthening and rehabilitation of the muscles of the user's body.

One preferred embodiment of the present invention provides a novel device and method for applying resistance to the neck and cervical spine, allowing for strengthening and rehabilitation of the user's neck.

FIG. 1 shows an embodiment of the present invention that functions as a neck exercise and rehabilitation device. The device 49 shown comprises a headband strap 1 that fits around a user's head in the manner of a headband, a rigid outer ring 2, and a webbing of elastomeric cords 3 that are threaded under tension between the headband 1 and the outer ring 2, thereby operably joining the headband strap 1 to the outer ring 2.

As further shown in FIGS. 1 and 8, a plurality of elastomeric cords 3, each of which are at one end threaded through preferably evenly spaced holes 4 and at their opposite end threaded through an eyelet cord fastener 7 affixed to the outer ring 2, thereby operably join the headband strap 1 to the rigid outer ring 2. In the embodiment shown, each of the elastomeric cords 3 is secured to the headband strap 1 by means of weaving the cord 3 through holes 4 in the headband strap 1 which are in close proximity and binding the cord 3 with hog ring 13, as shown FIGS. 1 and 8. These holes 4 are preferably distributed evenly around the entirety of the headband strap 1 in multiple sets of two holes 4 which are close in proximity, with the sets of holes 4 separated by a wider spacing. Any other suitable locking device may be employed to keep the cord 3 secured to the head band 1 thus, keeping the cords 3 essentially bound to the head band 1. In the embodiment shown in FIG. 1, the elastomeric cords 3 are affixed to the outer ring 2 by means of a plurality of screw eyes 7 affixed to the outer ring 2. Any other known suitable means for attaching and securing the elastomeric cords 3 to the headband strap 1 and outer ring 2, respectively, may be employed and are within the contemplation of the present invention. The embodiment of FIG. 1 further comprises a foam sleeve 10 that envelops the entirety of the outer ring 2.

In an alternative embodiment of the present invention, as shown in FIGS. 23 and 24, the elastomeric cords 3 may be threaded through a number of orifices 37 in the outer ring 2 and into the interior of the outer ring 2, attaching to a fixed termination point 36. Each of the cords 3 may be terminated at any preferred point within the outer ring 2. For example, each of the cords 3 could be terminated at an attachment point of the reinforcing ring 35. This allows utilization of longer, retractable cords 3 that extend the effective range of motion of the exercise device. In accordance with the principles of “Hooke's law,” this manner of attaching each of the retractable cords 3 is beneficial in gaining more effective range of motion with use of the exercise device 49 of the present invention.

The preferred embodiment shown in FIG. 1 includes a headband strap 1 that is flexible and may be made from a flexible and sturdy lightweight material, such as nylon. In the preferred embodiment shown, the headband strap 1 is preferably approximately 1.5 inches wide and 16 inches long, but the width and length of the headband strap 1 may vary and may be any size that is suitable for a comfortable fit around a user's head. As illustrated in FIG. 7, the headband strap 1 of the preferred embodiment has an adjuster section 6 for securing the strap 1 firmly to a user's head and for adjusting the length of the headband strap 1, by either loosening or tightening the headband strap 1, to provide a secure fit. A ratcheting knob 8, as shown in FIG. 8, may be provided to actuate clamping of the headband strap 1, thus securing the headband strap 1 securely to a user's head. It is understood that other materials may be used for the headband strap 1 and likewise, other connection materials (such as Velcro, for example) may be used to secure the headband strap 1 to the user's head. As shown in FIG. 8, a head band cushion 11 may be releasably secured to the adjustable headband 1 by Velcro, for example, or by other means known in the art.

FIG. 12 shows an over the head strap 46 that may fit over the top of a user's head and be engaged with the headband strap 1 as illustrated in FIG. 12. The over the head strap 46 in this particular embodiment may be secured in place by a Velcro attachment means at each opposing end of the over the head strap 46, as shown in FIG. 12. Any other suitable means for securing the over the head strap 46 may be employed, such as a snap or button fastener, or the like. Similarly, an under the chin strap 45 may also be provided to fit snugly under the user's chin, employing the same type of attachment means as described for the over the head strap 46, above. The headband assembly 5 shown in FIG. 12, comprised of the combination of the headband 1, the over the head strap 46, and the under the chin strap 45 provides additional stability to secure the exercise and rehab device 49 of the present invention firmly to the user's head while in use. Additional straps may be employed to obtain the desired functionality. For example, an additional similar strap (not shown) may be employed to hold or support the occipital part of the head. It should be understood that the ability of the device 49 to assist in applying traction is created with the use of the over the head and under the chin straps 45, 46 and adjustable head band 1 when combined with the appropriate opposing forces applied to the outer ring 2.

The configuration of the elastomeric cords 3, shown in FIGS. 1, 1A and 1B is a preferred arrangement that offers the desired resistant force to be applied to the user's body part in any direction. The preferred embodiment, thus, offers 360-degree negative and positive X-Y-Z AXIS omni-directional resistance variation without the need to modify the device 49. In the embodiment shown in FIG. 1, wheeled cord lock stoppers 9 are provided as cord locking mechanisms, which allow for the ability to modify the trajectory and tension of the elastomeric cords 3 and, thus, makes the device of the present invention easily and highly adjustable to serve the varying requirements of a physical rehabilitation and training device. The outermost position of stoppers 9 provides for more resistance, while positioning the stoppers 9 closer to the center of the device 49 lessens the resistance.

In the preferred embodiment shown in FIG. 1, each pair of elastomeric cords 3 exiting from the headband 1 are then threaded through the wheeled cord lock stopper devices 9, in the manner shown in FIG. 10B. Each of these cord lock stopper devices 9 may slide along a respective pair of elastomeric cords 3 and self-lock when in the desired position. The cord lock stoppers 9 preferably have a release tab to release the locking feature and thus allows the return of these “couplers” to the innermost position for a less resistive effect. It is advantageous to adjust the resistance in this manner for a variety of reasons, including accounting for the cords 3 potentially losing some elasticity over time and with intended use. The cord lock stoppers 9 may also be utilized to remove any slack exhibited by the elastic cords 3. Alternatively, a simpler cord lock device, such as the cord clip 12 shown in FIGS. 10A and 10B, may be employed in place of the wheeled cord lock stopper devices 9 described above.

The elastomeric cords 3 may be comprised of one continuous strand connected end to end after threading the cord 3 appropriately, but alternatively could be comprised of multiple pieces of cord connected at any connection point.

The outer ring 2 shown in FIGS. 6, 6A and 6B may be comprised of a lightweight plastic, such as the type of plastic tubing material that is typically used to make hula hoops. However, any suitable, preferably lightweight and sturdy material may be used to construct the outer ring 2 and is within the contemplation of the present invention. In a preferred embodiment, the outer ring 2 may be constructed of sectional pieces that allow for the ring to be broken down for ease of storage and portability. FIGS. 6A-6C show how a reinforcing rod 30 may be housed within the outer ring 2 to provide enhanced stability to the outer ring 2. The reinforcing rod 30 may preferably be constructed of a lightweight, sturdy and rigid material such as fiberglass or any other similar material known in the art. As shown in FIGS. 6A-6C, the respective ends of the reinforcing rod 30 are coupled together to form a closed loop. FIG. 11 shows a solid, pre-formed continuous reinforcement ring 35. The coupling of the ends of the reinforcing rod 30 is preferably achieved by a binding sleeve 32 in which the ends of the reinforcing rod 30 are inserted and secured. As can be seen in FIGS. 6A and 6C, the binding sleeve 32 may have holes 31 through which a cotter pin 33 may be inserted to keep the respective ends of the reinforcing rod 30 in place and securely fitted within the binding sleeve 32. Alternatively, a continuous reinforcement ring 35, like the one shown in FIG. 11, may be situated within the outer ring 2 as shown in FIG. 23.

Turning to the use of the device 49, as shown in FIGS. 1-5C, a user may secure the preferred embodiment of the invention to the head by securing the headband strap 1 around one's head. As shown in FIGS. 2 and 3, the user grasps the outer ring 2 to hold the outer ring 2 in a secured position. The user then may manipulate the position of the outer ring 2 or, alternatively, may motion the head in any direction, thereby creating a force that applies resistance to the user's neck muscles. The user may also utilize a combination of head movement and manipulation of the position of the outer ring 2 to effectuate the desired force and apply pressure to the neck muscles. More specifically, the user may manipulate the positioning of the outer ring 2 to create the desired resistance level and then rotate the head simultaneously and in unison with the outer ring 2 to achieve an even resistance to the head and neck rotation, while maintaining the self-governed resistance level through a complete range of motion in any desired direction. Because of the way the device 49 allows the user to employ head movement or to manipulate the position of the outer ring 2 in any direction and to apply whatever degree of resistance that is desired, the device 49 advantageously allows for the user to control the quality and the linearity characteristics of the resistance applied to the neck muscles. Therefore, the device of the present invention allows for flexion, stretching, strength training and exercise of neck muscles that otherwise are functionally inaccessible with traditional training and exercise methods and equipment.

FIG. 3 shows how the device 49 may be utilized by the user in a sitting position and the device 49 may alternatively be utilized in a standing position, as shown in FIG. 4. Whether in a standing or sitting position, the user may utilize the present invention in the manner described above. Alternatively, the user could stand or sit next to a wall and rest the outer ring 2 against the wall and employ head movement or manipulation of the positioning of the outer ring 2 to allow for the wall to facilitate applying the desired resistant force to the neck muscles. As shown in FIGS. 5A-5C, the user similarly may utilize the device 49 in a lying down position and use the device 49 resting against the ground or floor surface to facilitate the application of force to the neck muscles. As further shown in FIGS. 5A-5C, depending upon the manner in which the user is lying down, resistance can be exerted at a number of different angles, thus allowing for exercise of different muscles of the neck.

In another preferred embodiment, a hub ring assembly 48, as shown in FIGS. 9A and 9B, comprising a hub ring 15 and a handle 16 may be inserted securely inside the headband assembly 5. The handle 16 is fixedly secured to the hub ring 15. In the hub ring assembly 48 shown in FIGS. 9A and 9B, the handle 16 is secured to the hub ring 15 by means of handle retaining pins 17 inserted into opposing ends of the handle 16 in the manner illustrated in FIGS. 9A and 9B. The retaining pins 17 are then held in position by the headband assembly 5. The handle 16 may freely rotate by utilizing the pins 17 as spindles. The tension adjustment knob 8 may tighten the adjustable headband 1, thus securing the handle 16 tightly to the headband assembly 5, restricting entirely the movement of the handle 16 relative to the headband assembly 5. In this mode, as illustrated in FIG. 13A, rotational movement of the handle 16 by hand under tension provides resistance, thereby allowing the user to exercise the muscles required to produce the rotational movement, including the user's forearm and hand muscles. Alternatively, the tension adjustment knob 8 may be loosened slightly, thus allowing the hub ring assembly 48 to rotate within the headband assembly 5. In another embodiment of the invention (not shown), an inner and outer hub ring assembly with ball bearings therebetween may be provided to facilitate the rotational action of the hub ring assembly 48. The rotational ability of the hub ring assembly 48 may be hindered by tightening the headband assembly 5. Those skilled in the art will understand any other suitable means to allow for the rotation of the hub ring assembly may be applied.

In another embodiment of the present invention, the hub ring 15 may be inserted in the headband 1 and provided without a handle 16, as shown in FIG. 1B, allowing for the user to operate the exercise device in the manner illustrated in FIGS. 14A-E and FIG. 22 and described herein. For such embodiments, the user may operate the exercise device and perform the method of using the same by grasping the hub ring 15.

FIG. 18 shows an alternative embodiment of the present invention wherein additional resistance bands 24 are secured to the exercise device by connecting each of the bands 24 to a corresponding eye bolt 7a and connection ring 23 by utilizing resistance band connectors 27. Each resistance band 24 includes a resistance band termination loop 25a and thermal plastic or metal crimp connection 25 to facilitate affixing the resistance band to the resistance band connector 27. FIG. 18 also shows the utilization of eye bolts 7 as fasteners for connecting each cord 3 to the rotary hub ring 22. FIG. 18 further shows eye bolts 7a as connection points for the resistance bands 24.

FIGS. 15-17 show components of a rotating hub assembly 34, comprising two outer half hubs 20, 21, a rotary hub ring 22 (also shown in FIG. 19) and a hub connection ring 18 with a handle 16. In this particular preferred embodiment of the rotating hub assembly 34, the hub connection ring 18 may be adhered or bonded to the inside surfaces of the half hubs half hubs 20, 21. Alternatively the half hubs 20, 21 may be fastened to each other with screws, rivets or any other bonding method that will secure the rotary hub ring 22 and the hub connection ring 18. The hub connection ring 18 also acts as a spacer that determines the size of the gap for the rotary hub ring 22 to be situated within. The rotary hub ring 22 will be able to rotate freely within half hub assemblage of half hub 20, 21. FIG. 16 illustrates how the components of this hub ring assembly fit together and FIG. 17 illustrates a fully assembled rotating hub assembly 34. A suitable lubricant may be provided between the rotary hub ring 22 and the hub halves 20, 21 to facilitate the free rotation of the hub ring assembly 34 within the headband assembly 5.

FIG. 20 shows a rotating hub assembly 34 having two foam padding elements 28 adhesively secured to the rotating hub assembly 34. The foam padding elements 28 provide a means for the user to grip the rotating hub assembly 34 and to protect the wrists when utilizing the handle 16 while using the exercise device 49 of the present invention. The foam padding elements 28 and the foam sleeve 10 depicted in FIG. 1 may also provide the advantages of providing an adhesive or gripping effect on any surface upon which the device 49 is applied during use and further protecting such surfaces from damage that could occur due to the device 49 contacting said surfaces during use. FIG. 20 further shows a locking pin 29 which may be inserted into the rotating hub assembly 34 to prevent rotational movement of the rotating hub assembly 34 by securing the rotary hub ring 22 to the hub connection ring 18 or either hub half 20, 21 with the locking pin 29 inserted into pre-drilled aligned holes.

In yet another embodiment of the invention including a rotating hub assembly 34, as described herein, the device 49 may include elastomeric cords 3 or resistance bands 24 of varying gauge. The resistance provided by these elastomeric cords 3 and bands 24 varies and by rotating the rotating hub assembly 34, the user can rotate, reposition and orient the elastomeric cords 3 and the resistance bands 24 to different relative positions that offer varying levels of resistance.

FIG. 25 shows a hub hook handle 38 which may be utilized by a user of the device 49 of the present invention to allow for the user to exert pulling or pushing force by hooking the hub hook handle 38 to the rotating hub assembly 34, as shown in FIG. 26. Multiple hub hook handles 38 may be employed to facilitate the use of both arms simultaneously.

FIG. 27 shows an attachable weight 39, which may be attached to the device 49 of the present invention. In the embodiment shown in FIGS. 27 and 28, the weight 39 includes Velcro straps 41 that pass through slots 40 in the weight 39. The weight 39 shown in FIG. 28 is releasably secured by its Velcro straps 41 to the foam sleeve 10 of the embodiment shown.

In addition to the methods of using the device of the present invention already described herein, FIG. 14A illustrates a user utilizing an embodiment of the device 49 of the present invention from a sitting position, where one of the user's feet stabilizes the device 49 while the user's other foot and leg may be raised or lowered against the resistance provided by the device 49. FIG. 14B similarly illustrates use of the device 49 with the lowering or raising of the user's leg, but in a lying position.

Another method of using a preferred embodiment is illustrated in FIG. 14C, where the device 49 is secured by one of the user's arms by placing one hand through the hub ring 15 and applying lateral pulling force with the other hand, as shown in FIG. 14C.

FIG. 14D illustrates yet another method of using a preferred embodiment by resting the device 49 upon a seating surface and applying upward or downward force with the user's arm.

FIG. 14E illustrates yet another method of using a preferred embodiment where the user secures the device 49 between the user's legs, grasps the hub ring 15 and applies either a pulling or pushing force with the user's arm or arms. This method may similarly be employed with the user grasping the handle 16 or the headband assembly 5, rather than the hub ring 15 or a rotating hub assembly 34.

FIG. 22 illustrates another method of using a preferred embodiment of the present invention, where the user grasps the rotating hub assembly 34 and the foam sleeve 10 with one hand and then squeezes with the hand, thus exercising the user's hand grip muscles.

FIGS. 29 and 30 illustrate another method of using a preferred embodiment of the present invention, where the user grasps the handle 16 and positions the device 49 against the outside of a door frame 43 and may employ a pushing force, as shown in FIG. 30. Similarly, FIGS. 29A and 30A illustrate another method of using a preferred embodiment of the present invention, where the user grasps the handle 16 and positions the device 49 against the inside of a door frame 43 and may employ a pulling force, as shown in FIG. 30A.

FIGS. 31 and 32 illustrate the method of using a preferred embodiment of the present invention, where a weight 39 is attached to the outer ring 2 and the user grasps the handle 16 and utilizes a twisting force in either a clockwise or counterclockwise motion, inducing rotation of the outer ring 2. With the combined aid of the user circulating their hand and the weight 39, the resultant centrifugal force interacts with the flexing of the elastic cord 3 that in turn interacts with the outer ring 2 which then interacts with the weight 39 to cause rotation of the device 49.

Yet another method of using a preferred embodiment of the present invention involves the user grasping the outer ring 2 with one hand and grasping the rotating hub assembly 34 with the user's other hand, pulling with each hand in opposite directions, thus utilizing the user's own arms to create resistance from the pulling action of each of the user's respective arms. Alternatively, the user may push his or her hands together while grasping the outer ring 2 with one hand and grasping the rotating hub assembly 34 with his or her other hand.

Another method of using a preferred embodiment of the present invention involves the user bracing the outer ring 2 against or by utilizing the user's body for any desirable support and by controlling or supporting another part of the invention and applying pulling, pushing or a clamping force with any other part of the body.

An additional method of using a preferred embodiment of the present invention involves hooking the device 49 to an ordinary wall hook (not shown) secured to a wall, grasping the rotary hub assembly 34, and the user exerting a pulling force that is opposed by the resistance created by hooking the device 49 to a wall.

Yet another method of using a preferred embodiment of the present invention includes the step of grasping the handle 16 and rotating the hub assembly 34, while the elastic cords 3 are under tension, this allows for the isolation and the exercise of individual muscles found in a desired group of muscles.

Although the embodiments described herein and shown in the drawings are shaped substantially circular, the present invention may be constructed in any other shape. Further, the present invention may be constructed in a variety of different sizes, depending upon what is ideal for exercising or rehabbing particular muscles of different parts of the human body.

Having described the preferred embodiment of the present invention and methods for using the same, any number of changes, variations and improvements which may be apparent to those skilled in the art are within the scope of the invention claimed and described herein.
