1. Field of the Invention
The present invention relates to a shoe sole, and more particularly to a shoe sole having a resilient cushioning device for the heel portion thereof.
2. Description of the Prior Art
Typical shoe soles may comprise one or more bladders or air chambers formed in the shoe soles, to increase the resilience of the shoe soles, and to resiliently support the heel portions of the users.
However, the bladders or the air chambers formed in the shoe soles may not be used to effectively cushion the heel portions of the users.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional shoe soles.
The primary objective of the present invention is to provide a shoe sole including a resilient cushioning device for attaching to the heel portion thereof to effectively cushion the heel portions of the users, and thus to comfortably support the heel portions of the users.
In accordance with one aspect of the invention, there is provided a shoe sole comprising a resilient cushioning device engaging in a heel portion of the shoe sole, the resilient cushioning device comprising a lower frame member, an upper frame member disposed above the lower frame member, a coupling device for coupling the lower and the upper frame members together, and a number of cushioning members disposed between the lower and the upper frame members, and having a resilience to provide a cushioning force between the frame members, and to cushion users.
The lower and the upper frame members each includes at least one recess formed therein to stably receive and retain the cushioning members between the lower and the upper frame members. The coupling device includes at least one arm coupled between the lower and the upper frame members, to resiliently couple the upper and the lower frame members together.
Each of the lower and the upper frame members includes an inner peripheral portion having the arm coupled therebetween. The lower and the upper frame members each includes an opening formed therein to define the inner peripheral portion thereof.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
The resilient cushioning device 20 may be engaged into the heel portion 11 of the shoe sole 10 while molding the shoe sole 10, or may be engaged into the heel portion 11 of the shoe sole 10 after the shoe sole 10 has been molded, and includes two frame members 30, 40 arranged substantially parallel to each other (
The resilient cushioning device 20 further includes a number of resilient or spring balls or bladders or balloons or spherical or spatial cushioning members 50 disposed or arranged between the frame members 30, 40, and having a suitable resilience to provide a suitable cushioning force between the frame members 30, 40, and thus to suitably cushion the heel portions of the users.
The first or the lower frame member 30 is located below the second or the upper frame member 40, and includes one or more recesses 31 formed or provided in the upper portion thereof, and the upper frame member 40 also includes one or more recesses 41 formed or provided in the lower portion thereof, for stably receiving and retaining the spatial cushioning members 50 between the frame members 30, 40.
Each of the frame members 30, 40 includes an opening 32, 42 formed or provided in an inner portion thereof, to form or define an inner peripheral portion 33, 43 respectively. The resilient cushioning device 20 further includes a coupling means or device 60 resiliently coupled between the frame members 30, 40, to further suitably and resiliently couple the frame members 30, 40 together.
For example, as shown in
Alternatively, as shown in
The coupling device 60 may further include one or more spring or resilient stays 64 formed or extended from the frame members 30, 40 respectively, and arranged offset from each other, to allow the spring stays 64 to be arranged or located side by side (
The upper or the lower frame member 30 includes a catch 34 extended therefrom, and the lower or the upper frame member 40 includes a lock notch 44 formed therein for receiving the catch 34, and one or more protrusions 45 extended into the lock notch 44 thereof, for engaging with the catch 34, and for detachably or openably securing the upper and the lower frame member 40, 30 together, and to maintain the he upper and the lower frame member 40, 30 in parallel to each other.
In operation, as shown in
It is to be noted that the resilient cushioning device 20 may further include the other cushioning members 50 of different resilience, which may be selectively and changeably engaged into or disposed between the frame members 30, 40, according to the users' need, or according to the weights of the users, in order to suitably support various kinds of users.
As shown in
Accordingly, the shoe sole in accordance with the present invention includes a resilient cushioning device for attaching to the heel portion thereof to effectively cushion the heel portions of the users, and thus to comfortably support the heel portions of the users.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
