Abstract
ABSTRACT OF THE DISCLOSURE
The invention relates to a novel structure for a skate boot made of a synthetic material. In order to provide flexibility in the ankle area of such boots, the boots are con-structed of an upper shell and a lower shell. The lower shell consists of the heel, toe and sole portions of the boot, and the upper shell is movably attached to the lower shell and placed so that it surrounds the ankle of a wearer. In prior art arrange-ments, the upper shell is pivoted by rivets at two points on either side of the boot, and this arrangement is inconvenient in that it is not removable because of its use of rivets. In accordance with the present invention, the upper shell is re-movably attached to the lower shell by a button and buttonhole arrangement. In one embodiment, it is so connected at the rear of the boot. The novel boot also contains a reinforcing layer at the sole and toe portions of the boot.

Description
iS01 This invention relates to a novel construction ~or a -skate boot, and to a skate including such a skate boot. More specifically, this invention rela~es to a skate boot having an upper shell and a lower shell, and to means for removably attaching the upper shell to the lower shell.
It is well known in the art to make s~ate boots of synthetic material such as, for example, polyurethane, thermo-plastic rubber, and the material identified by the trademark ADEPRINE, instead of leather. Although there are advantages to making the boots of the synthetic materials, there are also difficulties. Thus, the synthetic materials are relatively ~`~
rigid in tha~ there is very little stretch to them. However, ~;
in use, it is necessary that the boot have a degree of flexib- `~
ility in the ankle area thereof.
To provide this degree of flexibility, boots of synthetic material are made in two portions; a lower shell, -;
including the toe, heel and sole of the boots, and an uppers~hell which is removably attached to the lower shell adjacent the top ~ ~ ;
:: .
rear part thereof and positioned to surround the ankles when the ~
20 boot is worn. The degree of flexibility is provided by pivot- ;~ ~ -ably anchoring, by means of rivets, the upper shell to the lower shell on the bottom end of the upper shell and on the right and `~
left hand sides of the skate. The use of rivets is inconvenient , in that it does not permit the easy removal of the upper shell ~
', from the lower shell for servicing or replacement thereof. ;
Additionally, the lower shell is molded as a single ~
~, unit in the production of the boot. However, there are two ~-, ~ conflicting requirements in each boot as follows~ the top part -`~ of the lower shell, encasing the upper part of the foot, should be flexible to permit the boot to be easily opened to receive the foot of a wearer and to conform to the shape of the foot;
on the other hand, the bottom, or sole, part of the boot, as well ,' "
~,, , ' `~
as the toe part, should be rigid to carry the weight of the wearer, to provide adequate stren~th for attaching the skate blade to the boot and to provide protection to the toe of a wearer.
It is therefore an object of the invention to provide a skate boot of the type described whose upper shell is removably ; attached to the lower shell.
It is also an object of the invention to provide a structure for a skate boot made of a relatively rigid material which includes a reinforced bottom, or sole, portion, and a - reinforced toe portion.
It is a still further object of the invention to pro-vl~e a method for producing the reinforced portions. ~h The first object is met by attaching the upper shellto the lower shell by a button and buttonhole arra~gement.
The second object is met by making the bottom, or .
sole, portion and the toe portion, in two layers, an outer layer and a more rigid inner layer.
The reinforced portion is produced by first molding the inner layer of a rigid material, and then placing the layer in the mold for the outer layer and molding the outer layer around the inner layer.
In accordance with a specific embodiment a skate boot ~ormed of a synthetic material comprises: a lower shell having a heel portion, a toe portion and a sole portion; and an upper shell disposed on the lower shell to surround the ankle of a ... .
wearer, wherein said upper shell is removably attached to said . lower shell by attachment means.
Said attachment m~ans preferably comprises a button and buttonhole arrangement.
Said attachment means may be disposed at the rear end of said boot and may comprise a single point attachment means .
, .
~5~L
thereat.
Said attachment means may comprise: a button member disposed at the rear end of said lower shell, and a mating buttonh~le disposed at the corresponding rear end of said lower shell.
Said button member may, in plan view thereof, be in the shape of a somewhat truncated triangle, said button heing fixed to said lower shell by a stem of a first length, and where-in said buttonhole may be T-shaped with a relatively wide trunk, the length of said trunk being greater than said first length;
whereby said upper shell is longitudinally movable relative to said lower shell.
In accordance with a further specific embodiment a skate boot formed of a synthetic material comprises: a lower shell having a heel portion, a toe portion and a sole portion, and an upper shell disposed on the lower shell to surround the ~-ankle of a wearer; wherein said sole portion and said toe portion comprise a reinforcement layer of a second synthetic material. ~ ;
Said second synthetic material is more rigid than said ~ ~
20 synthetic material. ,;
Said reinforcement layer comprises an inner layer integrally bonded to the outer layers of said toe and sole portions of said boot.
The invention will be better understood by a review of the following description, together with the accompanying draw- `
ings, in which:-Figure 1 is a perspective view of a skate boot in accordance with the invention, Figure 2 illustrates a preferred arrangement for movably attaching the upper shell to the lower shell;
Fioure 3 is a cross-section through III-III in Figure 2; and Figure 4 is a cross-section of the lower shell to illustrate the reinforced bottom, or sole, and toe portions.
Referring to Figure 1, a boot in accordance with the invention, illustrated generally at 1, comprises a lower shell 3 and an upper shell 5. The lower shell includes the heel, toe and sole 9 of the boot, and the upper shell is located to surround the ankle of a wearer. The boot also contains a re-movable sock-like member 7 and has a blade 11 attached to the underside of the sole 9. The boot can also be used for roller skates, in which case rollers rather than a blade would be attached.
In accordance with the invention, the upper shell is attached to the lower shell, to be removable therefrom by attachment means 13 at the rear end of the boot. In the illus-trated embodiment, the attachment means comprises a button 15 and buttonhole 17 arrangement which is better seen in Figures

The invention will be better understood by a review of the following description, together with the accompanying draw- `
ings, in which:-Figure 1 is a perspective view of a skate boot in accordance with the invention, Figure 2 illustrates a preferred arrangement for movably attaching the upper shell to the lower shell;
Fioure 3 is a cross-section through III-III in Figure 2; and Figure 4 is a cross-section of the lower shell to illustrate the reinforced bottom, or sole, and toe portions.
Referring to Figure 1, a boot in accordance with the invention, illustrated generally at 1, comprises a lower shell 3 and an upper shell 5. The lower shell includes the heel, toe and sole 9 of the boot, and the upper shell is located to surround the ankle of a wearer. The boot also contains a re-movable sock-like member 7 and has a blade 11 attached to the underside of the sole 9. The boot can also be used for roller skates, in which case rollers rather than a blade would be attached.
In accordance with the invention, the upper shell is attached to the lower shell, to be removable therefrom by attachment means 13 at the rear end of the boot. In the illus-trated embodiment, the attachment means comprises a button 15 and buttonhole 17 arrangement which is better seen in Figures
2 and 3. As seen in these Figures, the shape of the button in plan view is a somewhat truncated triangle, and the button~
~ hole is T-shaped with horizontal arms 19 and a relatively wide ~ -', 20 trunk 21. ~ ~ -With the arrangement, the upper shell is easily re~
movable from the lower shell for servicing or replacing the upper shell.
As seen in Figure 3, button 15 is connected to lower shell 3 by stem 16, and the length of stem 16, in the vertical direction, is less than the length of the button inthhe same dixectionO Thus, upper shell 5 is movable in a vertical, and therefore forward and rearward (longitudinal) directions, relative to the lower shell. In addition, because the upper shell is not constrained at the sides of the boot, as in the prior art arrangements, 'che upper shell is also movable in the lateral directions relative to the lower shell.
It will be appreciated that the attachment means illus-trated is only one of many possible arrangements. Thus, the shape of the button need not be as shown herein but could be, for example, round, and the buttonhole wo~lld then be of a corres- ~ -pondingly different shape, for example, a rectangular shaped opening.
In addition, the button could be disposed on the upper - ~;
shell and the buttonhole on the lower shell.
Further, because this arrangement allows the upper shell to be movable relative to the lower shell at ~s point of attachment, button and buttonhole arrangements could be disposed on both sides of the boot (replacing the rivets of the prior art) and all objects of the invention would still be met.
The boot comprises a synthetic material such as, but not restricted to, polyurethane, thermoplastic rubber, ADEPRI~E, etc. Although such materials are rigid relative to leather, as above discussed, it is flexible relative to the requirements in the sole and toe portions of the boot. To reinf~orce these parts, a second, more rigid, layer of material is used as shown in Figure 4. In this Figure, the boot is shown to comprise, in the sole and toe portions thereof, an outer layer 23, consisting of the material of the boot, and an inner layer 25 of a more rigid material. The inner, or reinforcement layer 25, will also be a sy~thetic material and could comprise, for example A.B.S.
material.
To produce the boot with the reinforcement, the inner -layer 25 is *irst formed in a mold. The molded layer is then inserted into the boot mold, and the mold for the boot is then formed around the inner layer. With this method, the inner layer is integrally formed with the outer layer.
Although specific em~odiments have been described, this was for the purpose of illustrating, but not limiting, the in-vention. Various modifications, which will come readily to the mind of one skilled in the art, are within the scope of the :
inv~ntion as defined in the appended claims.
