Boot-jacks
A monolithic jack (12) of sheet-like form (28) for removing ski-boots (14) having a rear shoulder (16), comprises a plate-like base (18) and two engagement means (20) each adapted to engage over a shoulder (16) of, and having a recess (202) to accommodate the heel (22) of, a respective one of a pair of the boots (14) when placed side by side on the base (18) in front of the means (20) which are to the rear of base (18) and face forwards. The member (28) is of metal, e.g. steel, or injection-moulded of thermoplastic plastics material, comprising a polycarbonate, with ABS or PETG. The base (18) has a non-slip upper surface portion (32), and comprises security means, e.g. aperture means (34), so it can be secured by screws to the floor. The base (18) also has a handle (36) for hanging up the jack (12). Integral strut means (38), to enable elevation of jack (12) to an angled position, are hinged at points (42), retracting into slots (44) in the bottom of base (18), and provided with stops (46) to prevent them from opening out too far. For carrying, jack (12) can be folded across its length at a hinge (50) or formed as two parts (183, 184), mutually identical, interengageable along its length by press-fit or slide-fit, by tongue-and-groove means (52, 54), with a connecting and/or reinforcing member (562) accommodated in recess means (561).
This invention relates to boot-jacks, that is jacks for removing boots or like footwear.
BACKGROUNDKnown jacks for use in removing ski-boots are awkward to use.
THE INVENTIONThe present inventor has realised that the awkwardness with prior jacks is that, to remove both boots, difficult movements, positions and changes of position are required, and this can be ameliorated by, in effect combining two jacks, one for each foot.
According to one aspect of the invention, there is provided a jack for use in removing one's feet from a pair of boots or other footwear items, each having a rearward, upward-facing shoulder, the jack comprising a base portion upon which the footwear items encasing the feet can be placed side by side, and two engagement means arranged side by side towards the rear of the base portion, each adapted to engage over a said shoulder of a respective said item placed as aforesaid to the front of the engagement means, the base portion and both engagement means together being of a sheet-like form with the engagement means having the form of being bent up from the base portion.
According to another aspect of the invention, there is provided a jack for use in removing one's feet from a pair of boots or other footwear items, each having a rearward, upward-facing shoulder, the jack comprising a base portion upon which the footwear items encasing the feet can be placed side by side, and two engagement means arranged side by side to the base portion, each adapted to engage over a said shoulder of a respective said item placed as aforesaid to the front of the engagement means, and each being spaced a substantial distance from the front of the base portion whereby a foot in one said item can be used to hold down the base portion while the other foot is pulled up to remove it from the other said item, the base portion and both engagement means together being of a sheet-like form with the engagement means having the form of being bent up from the base portion.
Each engagement means is adapted to engage over a said shoulder. This is to engage over a shoulder of a respective one of a pair, of said boots or other footwear, when placed on said base. The rearward shoulder (i.e. to the rear) of e.g. a ski-boot faces backwards, so that the engagement means for this embodiment face forwards.
The jack may have any one or more of the following features:
-
- the base is plate-like.
- the engagement means define a recess directed towards the location for the footwear to fit over a said shoulder. This arrangement is adapted for the two feet to be placed substantially parallel to each other, rather than with the two feet pointing in divergent directions.
- the recess is curved to accommodate the heel of the footwear.
- the recess is substantially semicircular.
- the engagement means have rounded corners.
- the engagement means are plate-like.
- a single monolithic member comprises said base and said engagement means.
- said member is of sheet-like form.
- said form has a U-shape with a long arm to provide said base and a short arm to provide said engagement means.
- said member is of metal, e.g. steel.
- said member is of plastics material, e.g. moulded.
- said member is of thermoplastic plastics material.
- said material comprises polycarbonate.
- said material comprises ABS (acrilonitrile-butadiene styrene).
- said material comprises PETG (polyethylene terephthalate glycol), e.g. with a 70% admixture of polycarbonate.
- said member is injection-moulded and/or is made by thermoforming.
- said base has a non-slip upper surface portion.
- comprising security means.
- comprising floor-fixing means.
- said floor-fixing means comprise aperture means in said base.
- the base has a handle at an end opposite to the engagement means.
- the handle is suitable to use as means by which to hang up the jack.
- the handle is formed in the sheet-like form
- comprising means to enable elevation of the jack to an angled position to enable seated removal of the footwear. Such means may be integral with the jack or a separate means, e.g. a wedge, forming part of a kit of parts therewith.
- the width of said base is substantially equal to that of a pair of said footwear placed side by side.
- the width of said base is in the range of from 15 to 30 cm.
- the width of said base is in the range of from 20 to 25 cm.
- which has a length equal to substantially the length of the intended footwear. Alternatively, it is possible to have it substantially shorter, down to about half this length, and still be able to use it by pressing with one heel (instead of with one whole foot) to release the other boot.
- it can be folded, preferably across its length, to facilitate (e.g. by reducing its size) portability.
- it is formed as (preferably two) interengageable parts that can be disengaged to facilitate portability.
- in which said parts have tongue-and-groove means by which they can be interengaged. These means may extend transversely of the jack but preferably extend longitudinally. They may be a press-fit, so that the parts engage by being pressed together, or a slide fit if the means extend only along a straight stretch of the base.
- said parts are substantially identical, e.g. to facilitate manufacture.
- comprises connecting means to interconnect said parts, which means is part of connecting and/or reinforcing means which comprise recess means to accommodate a connecting and/or reinforcing member and such member.
Another aspect of the invention provides any such jack in combination with a pair of footwear items intended for use with the jack. This may be a jack in which the spacing between said base portion and a said engagement means is substantially equal to the distance between a said shoulder and the bottom of the adjacent part of the respective said footwear item.
Another aspect of the invention provides a jack member comprising a base portion and engagement means arranged to the rear of the base portion, the base portion and engagement means together being of a sheet-like form with the engagement means having the form of being bent up from the base portion, and connecting means to connect the jack member side by side to another such member to form any such jack as aforesaid. This can be used for removing boots or other footwear having a heel with an upward and backward facing shoulder.
Such a member may have any one or more of the following features:
-
- said connecting means comprise part of tongue-and-groove means.
- said connecting means comprise part of tongue-and-groove means along one side of said base and a complementary-shaped part of such tongue-and-groove means along an opposite side of said base.
- said connecting means is part of connecting and/or reinforcing means which comprise recess means to accommodate a connecting and/or reinforcing member.
Another aspect of the invention provides a kit of parts for any such jack, comprising a pair of jack members, each being a jack member as aforesaid.
jack comprising a pair of jack members each separately as aforesaid.
A further aspect of the invention provides a jack comprising a pair of jack members each separately as aforesaid and a connecting and/or reinforcing member adapted to be accommodated by both members at once to hold them together.
In preferred embodiments:
-
- The base, e.g. as a plate, is made sufficiently wide and long to allow the user to stand with both feet on the jack (wearing a pair of the footwear) whilst using the pressure, or weight of the body, on one foot to hold down the jack and allow leverage (opposed forces, down and up respectively, by the two feet) by the wearer to pull the other foot out of its boot, shoe or other footwear. The rear hook-like form of the engagement means or grip has an elevation allowing enough height for the shoulder of a boot, shoe or other footwear heel to be inserted therein to be engaged or gripped. The hook-like grip has two curved insets (to provide the respective engagement means) cut out to allow the back of the boot, shoe or other footwear to be gripped for extra stability when leveraging the foot out of the same. The base plate and rounded grip are made out of a single piece, preferably a single moulding, to allow for increased durability and reduced complexity in manufacturing. The surface of the base plate is made non-slip to avoid accidents. There is a hole to provide a handle to facilitate portability. There may be provided a retractable, integrated or separate frame, member or other means to enable angled positioning of the base (with the back lower than the front) to facilitate seated boot removal if required. There may be provided a fixing mechanism to allow the device to be fixed to the floor if required, for security purposes and/or to aid the leverage.
- Although primarily designed for ski boots, the jack device can be used more broadly for walking boots, wellingtons and shoes—the dimensions may change slightly.
- The device is thus used to assist in the removal of boots or shoes but mainly ski boots, using double U-shaped insets on the raised rear ridge of the device to grip the heel of the boot or shoe, whilst applying downward pressure on the footplate with one foot, to allow the other foot to be leveraged from the boot or shoe. This is a mobile (portable) device which is mainly used when the wearer is standing. The device can also or alternatively be used for seated boot or shoe removal (i.e. when the wearer is sitting), e.g. in an angled position, or fixed to the floor for security (or added leverage) if required. For seated removal, wedge-shaped or other means are utilised to support the toe end of the device raised above its heel end.
- The device has two U-shaped insets instead of one. It can have a full foot plate for stability, allowing removal from each foot by just bending the knee and leaning forward onto the weight-bearing other foot. It uses weight applied by one foot to leverage the other foot out of the boot, with the position of one foot possibly being slightly in front of the other. It is simpler and less technical to manufacture than prior jacks and can therefore be cheaper. It is basically a portable/mobile device, that does not need to be fixed to the floor but can be if this is required, e.g. for security purposes. It allows for space on the base plate to enable the feet to be placed one foot slightly in front of the other during operation, for extra stability.
- A retractable, integrated or separate frame or other means may be used for elevation to an angled position to enable seated boot (or other footwear) removal.
- The material used for the jack should be a durable, light material enabling a single mould to be used to form the main device, allowing for portability and ease of production. The material and/or design have to be suitable for the device to withstand the envisaged stresses. Because of the upward stress on the rear curve, the device (or at least the curved part thereof) may need to be re-inforced, e.g. lined (e.g. inside the curve) with a suitable metal, e.g. steel, to prevent the device from fracturing at the curve; it should preferably then be coated with plastics. Also, the material should be washable for ease of maintenance and hygiene.
Without using this jack (i.e. not according to the invention), the following method would be used to remove a ski boot:
-
- Loosen all clips and bindings
- Lever forward the front lip of the boot
- Press down with the hand on the back, upward-facing lip of the boot
- Leverage foot forward and up—which often requires twisting your back into an uncomfortable position if executed whilst standing
- Or sitting down, crossing legs and pushing the back of the boot away from the calf to lever the foot out of the boot.
The present embodiments enable one to take the boot off without having to apply the pressure with the hand to the back of the boot, which often requires twisting one's back into an uncomfortable position, whilst leveraging the knee forward and the foot upwards, and therefore allow one just to bend forward after the foot has been extracted and remove the boot from the device.
A further aspect of the invention provides a method of removing a pair of boots or other footwear items each having a rearward, upward-facing shoulder, in which method there is used a jack comprising a base portion and two engagement means arranged to the rear of the base portion, the base portion and both engagement means together being of a sheet-like form with the engagement means having the form of being bent up from the base portion, said items are placed side by side on the jack and each engagement means is engaged over a said shoulder and the foot pulled out of that item of the pair.
A further aspect of the invention provides a method of removing a pair of boots or other footwear items each having a rearward, upward-facing shoulder, in which method there is used a jack comprising a base portion and two engagement means arranged to the rear of the base portion, the base portion and both engagement means together being of a sheet-like form with the engagement means having the form of being bent up from the base portion, said items are placed side by side on the jack to the front of the engagement means and each engagement means in turn is engaged over a said shoulder of a respective said item and the foot pulled out of that item of the pair while pressing against the base portion with the other foot.
While each engagement means in turn is engaged over a said shoulder and the foot pulled out of that item of the pair, this is preferably done while holding down the jack by means of the other foot placed on said base. Preferably, the feet are placed side by side on said base for the extraction. Preferably, the extraction of each foot is performed without the use of the hands, e.g. using a wall or car boot to lean on or for extra support. Preferably, the total extraction of both feet is performed without the use of the hands, apart from possibly to remove from the base an item of said pair from which its foot has been extracted. Alternatively, the two engagement means are used simultaneously, and the jack is held down by some other means, e.g. by the hands (e.g. by using ski-sticks) or by a connection to the floor, e.g. with floor bolts, and e.g. each foot is withdrawn in turn from its footwear.
Reference will now be made by way of example to the accompanying drawings, in which:
Referring to the drawings, the dimensions 10, 30, 40, 60, 70, 100, 240, 340 are 10, 30, 40, 50, 70, 100, 240, 340 mm respectively.
A jack 12 for removing ski-boots 14 having a rearward, upward-facing shoulder 16, comprises a base 18 and two engagement means 20 each adapted to engage over a said shoulder 16 of a respective one of a pair of said boots 14 when placed on said base 18. The rearward shoulder 16, i.e. to the rear of the ski-boot 14 faces backwards, so that the engagement means 20 face forwards.
The boots 14 each have a heel 22 with an upward and backward facing shoulder 16. Feet encased in the footwear 14 can be located side by side on the base 18, as seen in
The base 18 is plate-like. The engagement means 20 define a recess 202 directed (opening) towards the location 24 for the footwear 14, in order to fit over a said shoulder 16. This arrangement is adapted, as seen in
Said base 18 has a non-slip upper surface portion 32, and comprises security means 34 in the form of floor-fixing means 34 comprising aperture means 34 in said base whereby base 18 can be secured by screws (not shown) to the floor (not shown). The base 18 also has a handle 36 at its end opposite to the engagement means 20. The handle 36 is suitable to use as means 36 by which to hang up the jack 12. The jack 12 comprises means 38 to enable elevation of the jack 12 to an angled position, as shown in
The width 240 of said base 18 is substantially equal to that of a pair of said footwear 14 placed side by side, as seen in
Jack 12,
Alternatively, jack 12,
In the embodiments of
The jack 12 may be sold in combination with a pair of footwear 14 to use with the jack 12.
The jack member 183 or 184 (for use in removing boots or other footwear 14 having a heel 22 with an upward- and backward-facing shoulder 16) comprises a base 18 upon which a foot encased in the footwear 14 can be placed, and heel-gripping means 20 mounted to the base 18, the member 183 or 184 having means 52, 54 to connect it side by side to another such member 184 or 183, respectively to form a jack 12 as described above in relation to
Thus, there is employed a method of removing a pair of boots or other footwear items 14 each having a rearward, upward-facing shoulder 16, in which method there is used a jack 12 comprising a base 18 and two engagement means 20, and each engagement means 20 in turn is engaged over a said shoulder 16 (by placing each boot 14 in turn with its heel 22 in to one or other recess 202 of engagement means 20 so that its shoulder 16 engages under the edge defining recess 202) and the foot pulled out of that item 14 of the pair. This is done while holding down the jack 12 by means of the other foot placed on said base 18. The feet are placed side by side on said base 18 for the extraction. The extraction of each foot is performed without the use of the hands; and the total extraction of both feet is performed without the use of the hands, apart from possibly to remove from the base 18 an item 14 of said pair from which its foot has been extracted.
