WHEEL CASTER GLIDE
A wheel caster glide receives caster wheels therein and employs wheel engaging members to keep the glide removably engaged with the wheel in absence of sufficient removal force.
This invention relates to caster wheels, and more particularly to a wheel caster glide for receiving caster wheels therein.
With items having castor wheels, such as furniture articles, it is often desirable to provide a protective member between the wheel portion and the floor or carpet, in order to minimize scratching of floors or to spread the weight of the furniture over a larger area to minimize deformation of the carpet resulting from long term compression from the weight of the furniture article. These protective members have typically been disk shaped members, but they are easily disassociated from the wheel if the furniture is lifted or moved, resulting in scratching or marring of the floor from the wheel or of excessive compression of the carpet in a small area as a result of the user not realizing that the protector has become disassociated from the wheel. This can lead to frustration and annoyance for the user.
SUMMARY OF THE INVENTIONIn accordance with the invention, a wheel caster glide comprises a receiving member for receiving a caster wheel therein, providing a larger base for engagement with a floor.
Accordingly, it is an object of the present invention to provide an improved wheel caster glide.
It is a further object of the present invention to provide an improved wheel caster glide that receives a caster wheel in removable engagement.
The subject matter of the present invention is particularly pointed out and distinctly claimed in the concluding portion of this specification. However, both the organization and method of operation, together with further advantages and objects thereof, may best be understood by reference to the following description taken in connection with accompanying drawings wherein like reference characters refer to like elements.
The system according to a preferred embodiment of the present invention comprises a member adapted to engagingly receive a caster wheel therein to provide an improved base for placement on a floor or carpet.
Referring to
The device can be manufactured in various sizes to accommodate various caster wheel configurations and sizes.
Accordingly, an improved wheel caster glide is provided that stays engaged with the wheel unless explicitly removed by the user.
While the illustrated embodiment shows the engaging lips 16, 16′ as extending substantially the width of the walls of portion 14, this is not required. An the lip portions can extend only a portion of the width, for example in a 6 cm wide portion 14, the lips may be 8 mm in length. Further, while illustrated at the peripheral edge, the lips may suitably be positioned lower in the wall. In a particular embodiment, the upper portion of the lip is 8 mm below the top edge of the wall of portion 14, the lip is 8 mm in length, and the lip is 1 to 2 mm in height, extending into the well region less than 1 mm. An alternative version of the device employs a single lip portion 16 or 16′, rather than both, as a single lip portion.
The while the illustrated embodiment provides a substantially circular configuration of the base portion of the wheel castor glide, it can be of other configurations, such as square, rectangular, or multi-sided, whether regular equal shape edges or irregular.
A typical material of which the wheel castor glide is made is plastic, such as by injection molding, but other manufacturing methods and materials can be employed.
While a preferred embodiment of the present invention has been shown and described, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from the invention in its broader aspects. The appended claims are therefore intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
Claims
1. A wheel caster glide, comprising:
- a wheel receiving portion; and
- a wheel engaging portion for removably engaging the wheel to encourage the wheel and caster glide to remain in engaged relation.
2. The wheel caster glide according to claim 1, wherein said wheel receiving portion comprises at least first and second opposing members defining a space therebetween for accommodating a caster wheel therein and wherein said wheel engaging portion comprises at least one stop member defined on one of said first and second members for providing a stop to resist removal of the castor wheel when accommodated in said space.
3. The wheel caster glide according to claim 1, wherein said wheel engaging portion comprises a raised stop member along a face or edge of one of said first and second members extending in a direction of said space.
4. The wheel caster glide according to claim 3, wherein said raised stop member extends substantially along an entire face or edge of one of said first and second members.
5. The wheel caster glide according to claim 3, wherein said raised stop member extends less than along substantially an entire face or edge of one of said first and second members.
6. A wheel caster glide, comprising:
- a wheel receiving portion having a receiving region of width equal to or greater than the diameter of a wheel to be received therein; and
- a wheel engaging portion for defined to provide a width region in said wheel receiving portion less than the diameter of the wheel, whereby a wheel is restrained against removal from said wheel receiving portion by engagement of the wheel and said wheel engaging portion, absent sufficient removal force to deform the engaging portion or the receiving portion or the wheel engaging the wheel, for encouraging the wheel and caster glide to remain in engaged relation absent sufficient removal force.
7. The wheel caster glide according to claim 7, wherein said wheel engaging portion comprises at least one stop member defined in said wheel receiving region.
8. The wheel caster glide according to claim 7, wherein said wheel engaging portion comprises a raised member for narrowing a portion of said receiving region width.
9. The wheel caster glide according to claim 8, wherein said raised member extends substantially along a length of the wheel.
10. The wheel caster glide according to claim 8, wherein said raised member extends less than substantially a length of the wheel.
