Description
Background of the Invention
This invention relates to devices for securing an object to a support, and more particularly relates to a harness for securing a child in a conventional chair. The invention also relates to a method of using a harness to secure an object to a support, and more particularly relates to a method of using a harness to secure a child in a chair.
Numerous devices and methods have been proposed for retaining an object or child in a conventional chair. U.S. Pat. No. 4,235,474 to Rosenberg discloses one such device. The Rosenberg device has a pocket which fits over a back portion of a chair and has a baby holding section having two ties which are used to tie a baby to the chair. The Rosenberg device may be useful however, it does not appear to accommodate chairs with back portions of different sizes and it requires that a knot be undone when the baby is to be removed from the chair. The removal of a knot can be time consuming in the event that the child must be removed in an emergency.
Other U.S. patents such as U.S. Pat. Nos. 1,429,867 to Goldsmith; 2,875,816 to Langefeld; 2,960,149 to Throssel; 3,186,762 to Lucas; 3,828,994 to Hollins; and 4,402,548 to Mason relate generally to devices which incorporate a separate seat for the child to sit on or relate to a belt arrangement for securing a conventional child seat to an automobile seat. Hollins discloses an apparatus for transporting articles on a automobile seat however no provisions appear to be provided for securing a child rather than articles to the seat.
The invention disclosed herein provides an advance in the art by providing a harness which can be used to secure objects, in general, to a support such as a chair having virtually any size of back portion and provides a harness which is versatile enough to harness a child to such a chair. Moreover, the harness is adapted to be comfortable to the child while permitting easy removal of the child from the harness thereby reducing risk of injury to the child in the event of an emergency.
Summary of the Invention
The invention provides a harness for securing an object to a support, the harness comprising a flexible longitudinal strap member having first and second opposite end portions and an intermediate portion between the end portions. First and second strap portions having respective inner portions and respective outer end portions, are connected to the intermediate portion such that the first and second strap portions extend transversely to the longitudinal member. Connectors are provided for connecting respective outer end portions of the first and second strap portions to the first end portion of the longitudinal member to form a cradle. Third and fourth strap portions having respective inner portions and respective outer end portions are also connected to the intermediate portion such that the third and fourth strap portions extend transversely to the longitudinal member. Connectors are provided for connecting together respective outer end portions of the third and fourth strap portions to secure same about an object. A stretchable elastic loop is connected to the second end portion of the longitudinal member. The loop is operable to receive the support therein such that the support extends through the loop and such that the loop embraces the support.
The harness may be used to secure an object, in general, to an upstanding support such as a chair by using the elastic loop to secure the longitudinal member to a back portion of the chair, looping the first and second strap portions around the object, looping the first end portion of the longitudinal member under the object and connecting the first end portion to the first and second strap portions. Optionally, the third and fourth strap portions may also be wrapped around the object and outer end portions thereof connected together.
Preferably, when the harness is used to secure a child, the first and second strap portions and the first end portion of the longitudinal member are operable to form a cradle extending about the child's waist and crotch.
Also preferably, when the harness is used to secure a child the third and fourth strap portions are operable to be adjustably positioned both longitudinally and transversely of the longitudinal member to place the third and fourth strap portions comfortably about the upper torso of the child.
In using the harness to secure a child to a chair, a back portion of the chair is passed through the elastic loop such that the elastic loop embraces the back portion of the chair. An end portion of the longitudinal strap member is then placed on a seat portion of the chair. The child is then placed on the end portion such that the end portion is disposed between the seat portion and the child. The end portion is then moved upwards between the child's legs and the first and second strap portions are wrapped around the waist of the child. The first and second strap portions are then connected to the upwardly extending end portion of the longitudinal strap member and the third and fourth strap portions are wrapped around the upper torso of the child. The end portions of the third and fourth strap portions are then connected together.

Disclosure
Referring to FIG. 1, a harness 10 according to a first embodiment of the invention is shown restraining a child 12 in a chair 14. The harness is secured to a back portion 16 of the chair and serves to retain the child on a seat portion 18 of the chair.
Referring to FIG. 2, the harness, shown generally at 10 comprises a flexible longitudinal member 20 having first and second opposite end portions 22 and 24 respectively and an intermediate portion 25 disposed between the end portions. In the embodiment shown, the flexible member is made of conventional one-inch wide polyethylene webbing commonly used on devices such as life jackets and the like. It has been found that if the harness is to be used to restrain a child, the longitudinal member is preferably formed in a thirty-two inch length of polyethylene webbing. This permits the harness to be used with most children.
The first end portion 22 is folded back upon itself to form a loop 26. The loop is permanently formed by sewing a portion 28 of the first end portion 22 onto itself using conventional stitches 30. Preferably, the stitches are formed in a square pattern surrounding an X pattern.
A first unitary strap 32, approximately twenty-five inches long, is connected to the longitudinal member 20. The strap has first and second strap portions 33 and 35 having respective outer end portions 34 and 36. The first and second strap portions are secured to the intermediate portion of the longitudinal member approximately fourteen inches from the loop 26. The first and second strap portions are connected to the longitudinal member by a second set of stitches 38 formed in a square pattern surrounding an X pattern and thus are securely and unadjustably fixed to the longitudinal member such that the first and second strap portions extend transversely to the longitudinal member. The stitches thus act as first connecting means for connecting the first and second strap portions to the intermediate portion of the longitudinal member.
The first and second outer end portions 34 and 36 are fitted with complementary halves of a conventional strap connector such as a standard side release buckle available from Anchor Marine and Canvas of North Vancouver, British Columbia, Canada. In FIG. 2, a female portion of the standard side release buckle is shown at 40 and a male portion of the buckle is shown at 42. The male and female portions cooperate to act as second connecting means for connecting the first and second outer end portions 34 and 36 together. The male portion 42 has a conventional slidable buckle/strap fastener 44 for permitting adjustment of the connector relative to the end portion to which it is connected to permit adjustment of the tightness of the first and second strap portions about the child.
A second unitary strap 46, approximately twenty-five inches long, and having third and fourth strap portions 37 and 39 respectively is connected to the longitudinal member 20 between the first strap portion 32 and the second end portion 24 of the longitudinal member by a FAST-TAB (trademark) slidable connector 47 (available from Anchor Marine and Canvas of North Vancouver, British Columbia, Canada.
The slidable connector 47 is a generally square piece of plastic having four elongated slots 49 arranged in a square pattern. The longitudinal member 20 is threaded through two longitudinally opposite elongated slots 49.1 and the second strap is threaded through two transversely opposite elongated slots 49.2 which are adjacent the longitudinally elongated slots 49.1.
The slidable connector 47 adjustably connects the second strap 46 and hence the third and fourth strap portions 37 and 39 to the longitudinal member 20 such that the third and fourth strap portions are adjustable relative to the longitudinal member, in a first direction 48 which is parallel to the longitudinal member 20 to permit placement of the third and fourth strap portions about the chest of the child. The slidable connector further renders the third and fourth strap portions adjustable relative to the longitudinal member in a second direction 50 which is perpendicular, or transverse to the longitudinal member 20 to permit placement of the third and fourth strap portions transversely of the longitudinal member. The ability to slide the third and fourth strap portions in the first and second directions permits them to be adjusted relative to the longitudinal member 20 to ensure that they rest comfortably on the child.
For example, the third and fourth strap portions may be moved in the first direction 48 to permit proper positioning thereof relative to the child's arms and may be moved in the second direction 50 to permit proper positioning about the child's upper torso. The slidable connector 47 thus acts as third connecting means for connecting the third and fourth strap portions to the intermediate portion of the longitudinal member and the slots in the connector act as adjusting means for adjusting the third and fourth strap portions longitudinally and transversely of the intermediate portion.
The third and fourth strap portions 37 and 39 have respective first and second outer end portions 52 and 54 fitted with complementary halves of a conventional strap connector such as a standard side release buckle similar to that described above. A female portion of the standard side release buckle is shown at 56 and a male portion of the buckle is shown at 58. The male and female portions cooperate to act as connecting means for connecting the first and second end portions 52 and 54 together. The male portion has a conventional buckle/strap fastener 60 for permitting adjustment of the connector relative to the end portion 54 to permit adjustment of the tightness of the third and fourth strap portions when secured to the child.
A stretchable elastic loop 62 having a connecting portion 63 is securely fastened to the second end portion 24 of the longitudinal member 20 by a third set of stitches 64 formed in a square pattern surrounding an X pattern. The loop is secured to the end portion such that the loop tends to extend in a plane 65 perpendicular to the longitudinal member 20.
Referring to FIG. 3, the stretchable elastic loop 62 is formed from a two-inch wide portion of flexible polyester braided elastic material, available from Belding Corticelli Inc. of Toronto, Ontario, Canada. The material is formed into a closed elastic loop shown generally at 66. The loop has first and second co-terminus openings 80 and 82 extending therethrough which permit an object to pass unobstructed through the loop. When the elastic loop 66 is in a relaxed and compressed state i.e. it is not stretched and opposite portions of the loop are laid flat, one upon the other, the loop has a relaxed diameter 68 measuring twelve inches. Using the braided elastic material specified above, when the elastic loop 66 is stretched out, into the position shown in broken outline, i.e opposite ends of the loop are pulled apart, the loop has a stretch diameter 70 measuring twenty-seven inches.
It will be appreciated that the elastic loop 66 may be stretched such that items of various shapes may be passed through the loop and may be securely held therein by virtue of the inherent elasticity of the loop material which causes the loop to embrace such item. Thus, the elastic loop 66 may be used to secure the harness 10 to items of various shapes and more particularly may be used to secure the harness to chairs having uniquely shaped back portions which act as upstanding supports for the longitudinal member 20 of the harness. The harness 10 is thus rendered quite readily adaptable to be secured to a wide range of chairs, while providing easy removal of the harness from such chairs. The harness 10 may be removed simply by stretching the loop and removing it from the item to which it is secured.
Operation
The operation of the apparatus according to the first embodiment will be explained in the context of securing a child to a chair. It should be borne in mind however, that the harness may be used to secure objects other than children to any support around which the elastic loop 66 may be secured. It is envisaged that the harness be secured to an upstanding member such as a back portion of a chair however this is a practical limitation in securing a child to a chair and need not be a limitation when securing objects in general to a support member in general (i.e. the support member need not necessarily be a chair).
Referring to FIG. 4, in using the harness 10 to secure the child 12 to the chair 14, the elastic loop 66 is first looped around the back portion 16 of the chair. The elastic loop is positioned on the chair such that the longitudinal member 20 hangs downward over the seat portion of the chair. For the securing of most children, the elastic loop 66 may be placed at the expected approximate height of the child's head.
The first end portion 22 of the longitudinal member 20 is then placed on the seat portion 18 of the chair such that it rests approximately centrally thereon. The child 12 is then placed on the seat portion 18 such that the longitudinal member is disposed between the seat portion and the child wherein the first end portion 22 extends between the child's legs. The first end portion 22 is then brought upwards between the child's legs such that the loop 26 in the first end portion 22 is in front of the child.
Next, the first and second strap portions 33 and 35 of the first strap 32 are wrapped around the child's waist and brought in front of the child. Referring to FIG. 5, the female portion 40 of the strap connector is then threaded through the loop 26 (shown in broken outline). The female portion is then connected to the male portion 42, thereby connecting together the end portions 34 and 36 and the first end portion 22 of the longitudinal member. The first adjustment provision 44 on the connector 42 may then be adjusted to secure the first strap portion about the child with any desired degree of tightness. By threading the female portion 40 through the loop 26, the first end portion 22 of the longitudinal member 20 is connected to the first and second portions strap 33 and 35. The loop 26 thus acts as connecting means for connecting the first end portion of the longitudinal member to the first and second strap portions. A cradle is thus formed about the waist and crotch of the child.
Next, referring to FIG. 1, the third and fourth strap portions 37 and 39 are wrapped around the upper torso of the child. The slidable connector 47 is used to slide the second strap portion relative to the longitudinal member, in the first direction 48, to place the second strap portion in a desired location relative to the child, such as in a position wherein the third and fourth strap portions 37 and 39 extend just beneath the arms of the child. The female and male connector portions 56 and 58 are then connected together to secure the third and fourth strap portions about the child. The buckle/strap fastener 60 may then be used to adjust the tightness of the third and fourth strap portions about the child and the slidable connector 47 may be used to slide the third and fourth strap portions in the second direction 50 to position the connector portions 56 and 58 in a position comfortable to the child. The child is thus comfortably restrained in the chair and is prevented, by the harness, from falling forward and from falling to either side of the seat portion of the chair.
Removal of the child from the harness may be achieved by performing the above steps in the reverse order.
In the event of an emergency, the child need not be removed from the harness, but rather may remain fastened in the harness by the first and second straps and the first end portion. The child may be removed from danger by stretching the elastic loop 66 and pulling it off of the back portion 16 of the chair whereupon the harness may be used as a conventional child restraint device in the event that the child can walk, or the harness may simply be gathered in an adult's hands if the child is to be carried.
It will be appreciated that the harness is adapted to be comfortable to the child while permitting easy removal of the child from the chair, thereby reducing risk of injury to the child in the event of an emergency.
Alternatives
Referring to FIG. 6, in an alternative embodiment, the loop 26 is not permanently stitched to the first end portion 22, but rather, an adjustable loop 26.2 is formed in the first end portion 22.2. A conventional strap connector 72 is used to connect a portion of the first end portion 22.2 onto itself. The use of a conventional strap connector permits the size of the loop 26.2 to be adjusted such that the first end portion 22.2 may be tightened as desired upon the crotch of the child.
Referring to FIG. 2, in an alternative embodiment, the stitches 38 connecting the first strap portion 32 to the longitudinal member 20 may be replaced by a second slidable connector (not shown), similar to the first slidable connector 47 used to connect the second strap portion 46 to the longitudinal member 20. This second slidable connector may be used either alone or in conjunction with the connector 72 referred to in FIG. 6, as a means for adjusting the distance between the loop 26 and the first and second end portions thereby providing the capability of adjusting the tightness of the first end portion 22 about the crotch of the child.
The embodiments disclosed are illustrative of the invention only and are not to be construed as limiting the invention as construed in accordance with the accompanying claims.
