1. Field of the Invention
This invention is directed toward the field of lower body support devices. More particularly, this invention relates to a lower body support device for providing improved support, stability, and mobility for users of the device.
2. Discussion of Prior Art
Many occupations require workers to assume kneeling positions in order to attend the task for which they are employed. Unfortunately, assuming a kneeling position for an extended period, or repeatedly, causes those in such a position discomfort, cramping, muscle fatigue, or other similar problems.
Many devices have been proposed over the years to alleviate the discomforts associated with kneeling positions. For instance, U.S. Pat. No. 1,296,522 to Holsey shows a simple knee pad device. Similarly, U.S. Pat. No. 1,547,166 to Davidison shows a slightly more sophisticated knee pad. However, neither device provides much in the way of actual support or cushioning. That is, even though the knee is elevated above whatever surface on which the knee pad rests, the user's weight still stresses the knee.
In U.S. Pat. No. 2,627,301 to Emmett, a knee board is shown. Although this device implements a recognizable pad to cushion the knee, it does not allow much mobility to a standing user. As such, is utility its diminished.
In U.S. Pat. No. 4,377,309 to Mengshoel another knee board device is illustrated. Through a variety of configurations, Mengshoel discloses a more portable device than previously shown. Additionally, the device has provision for a seat element, which takes some stress off the user's knees. However, the user's weight still passes through the user's ankles. Moreover, in the J-shaped ankle configuration the user's leg may separate from the pad, especially when employed in a dynamic occupational setting. Additionally, the O-shaped ankle configuration, the ability of the user to equip the device is impaired. That is, putting one's foot through the O-shaped ankle configuration is difficult.
In U.S. Pat. No. 4,772,071 to Richards, a complicated knee pad device is shown. Said device includes a frame with a knee pad section, a seat section, and a mid-shin floor engaging member. This device is hampered by its obvious complexity. Moreover, it is designed with an integrated knee pad, limiting the user to employing that knee pad exclusively. Additionally, this device is not particularly stable, being prone to side-to-side rolling.
In U.S. Pat. No. 5,865,507 to Earl, a kneeler is shown. This kneeler allows a certain amount of the user's weight to pass through the seat incorporated in the frame of the device. However, a user of the device cannot walk around with this device attached to their legs. As such, the user would have to carry such device with them, greatly diminishing its utility.
As such, there is a void in the prior art in the field of lower body support devices. The prior art lacks a device which provides improved lower body support, mobility, and stability in a less complex configuration. The present invention fills this void.
In accordance with the present invention, a lower body support device is shown herein. The lower leg of the user is positioned such that the knee of the user rests within the area defined by a knee frame, the shin of the user rests within the area defined by a bend frame, and the ankle of the use rests in the region of an ankle frame. A strap bar means connected to the knee frame allows for the securing of a knee pad, such knee pad is user chosen, worn by the user and strapped to the knee frame via the strap bar means. A seat insert is secured to the top of the ankle frame. The user wears one leg support device on each leg.
While resting on a surface, the bottom of the knee frame and the bottom of the ankle frame, and possibly the knee pad worn by the user, contact said surface. Preferably, the buttocks of the user rests on the seat insert, which transfers a significant portion of the weight of the user to the surface via the frames. The ankle frame and knee frame greatly limit the possibility of side-to-side motion. Additionally, the user may stand and walk while employing the leg support device.
Accordingly, the objects and advantages of the invention are:
A) to provide a lower body support device which allows the user to choose a knee pad to fit within the knee frame of the device, whereby such knee pad may be any of several available on the open market;
B) to provide a lower body support device which may be worn and employed by a user while kneeling, standing, or walking;
C) to provide a lower body support device which transfers a significant portion of the weight of the user through the device and away from the knee and joints of the user; and
D) to provide a lower body support device which allows improved stability while employed in a kneeling position;
Further objects and advantages are to provide a lower body support device with a user chosen knee pad which may be easily replaced when said knee pad is no longer useful in the discretion of the user. Still further objects and advantages will become apparent from consideration of the ensuing description and drawings.
In its most simple configuration the lower body support device comprises three basic elements. First, there is a framing means 24 to support the leg of the user. Second there is a seating means 26 providing a region on which the user may sit. Once seated, a substantial amount of the user's body weight is transferred through the device, away from the user's leg, and onto the surface upon which the device rests. Third, there is a fastening means 28 for attaching the user to the device.
In the preferred embodiment of the invention, the framing means 24 is divided into three parts. As shown in
Knee frame 10 receives the knee of the user. Knee frame 10 is designed to accommodate both the knee of the user as well as a knee pad 56 worn by the user. The user may choose a knee pad 56 to it within the region defined by knee frame 10. Such knee pad 56 should have knee pad straps 58 and may be any of several available on the open market. As shown in
Additionally, two strap bars, strap bar one 20 and strap bar two 22, are connected to the knee frame 10. Once the user dons the chosen knee pad 56 and inserts the knee of the user (with knee pas in place) within the open region of knee frame 10, the straps of the knee pad 56 are fitted through strap bar one 20 and strap bar two 22. Then, the user fastens the knee pad straps 58 behind the knee of the user, securing the knee pad 56 and the user to the device.
Bend frame 12 receives the shin of the user. As may be seen in
Ankle frame 14 receives the ankle of the user. Ankle frame 14 connects to bend frame 12. The upper portion of ankle frame 14 receives seat insert 18 by using an ankle frame means 62, which is discussed in more detail below. The upper portion of ankle frame 14 comprises two hollow tubes. As may be seen in
Seat insert 18 is slightly inclined when placed within the hollow tubes of the ankle frame 14. Seat insert 18 includes a seat rod 40. As seen in
In the preferred embodiment of the ankle frame means 62, one of the hollow tubes of the ankle frame 14 includes an ankle frame hole 16 for accepting a seat fastening pin 48, which secures the seat insert 18 to the ankle frame 14. Correspondingly, the long seat rod end 42 also has a long seat rod hole 44 for accepting the seat fastening pin 48. Once the user's leg is fitted onto the device, seat insert 18 is placed within the hollow tubes of ankle frame 14. Then, seat fastening pin 48 is inserted through the ankle frame hole 16 and the long seat rod hole 44, securing the seat insert 18 to the ankle frame 14.
While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. Many variations are possible and some are as follows.
First, the materials used in the lower body support device can be wood, metal, plastic, composite, or other materials commonly used in the knee pad, body armor, or similar industries. Different materials allow differing strengths and weaknesses which would be used to match consumer preferences, needs, and budget restraints.
Second, the device may be equipped with a board 50. As shown in
Third, the ankle frame 14 may be configured as shown in
Fourth, the device may be configured in a P-shape. As shown in
Fifth, the seating means 26 may be attached to the framing means 24 in many ways common in the prior art. Such ways of attachment, generally referred to as ankle frame means 62, include, but are not limited to hinges, caps, clips, clamps, straps, screws, and latches.
Sixth, as shown in
The embodiments above-discussed are to be considered illustrative and not restrictive. Many more embodiments may be configured using combinations of the embodiments above-discussed. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
Conclusions, Ramifications, and Scope
The utility of lower body support device is apparent. In the preferred embodiment, the device provides improved lower body support, mobility, and stability in a less complex configuration.
Lower body support is obtained via the framing means and the seating means. When a user sits upon the seat, the device transfers a significant portion of the weight of the user to the surface upon which the device rests via the frame.
The user may use the device in a kneeling position, a seated-kneeling position, or while walking. Thus user mobility is improved.
The device provides exceptional stability, resisting side-to-side movement and corresponding rotation. That is, the shape of the knee frame and the bottom portion of the ankle frame add stability to the device.
Another benefit of the invention is its use of knee pads for sale on the open market. As such the user may choose from a large number of existing, readily available knee pads. Moreover, once a user chosen knee pad wears out, the user may simply replace the knee pad without having to replace the entire device.
The above-discussion is to be considered illustrative and not restrictive. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
