Description

TECHNICAL FIELD

The present invention relates to a reinforcing element for an article of clothing, in particular, for a soccer goalkeeper glove that allows bending in a first direction, but resists bending in a second direction.

BACKGROUND OF THE INVENTION

Apart from thermal isolation, gloves typically serve to protect the hands. Injuries are avoided by blocking or at least cushioning mechanical impacts to the hand. For example, work gloves are typically made from stable and tear-resistant materials to reduce the risk of cuts to the hand.

A goalkeeper glove, for example, fulfills several requirements. Apart from improving the grip on the inner side of the hand, it is important to protect the hand against the significant mechanical loads arising when deflecting a sharply shot ball. A particular risk for a goalkeeper is the hyperextension of individual fingers or the thumb. When a goalkeeper tries to deflect a ball with an extended hand, there is the risk that one or two fingers of the extended hand, which barely contact the ball, are subjected to the full impact of the ball and hyperextended. Straining or even breaking a finger or the hand is a possible consequence. It has, therefore, been known to provide goalkeeper gloves and gloves for sports (e.g., snowboard gloves), where the hand is subjected to similar loads, with active reinforcing elements. These reinforcing elements allow for bending of the hand in a gripping direction, but they block a bending of the extended hand into the opposite direction, i.e., in the direction of a hyperextension. In the case of a goalkeeper glove, the extended hand and in particular individual fingers and the thumb are actively supported by the glove when deflecting a sharply shot ball.

To obtain the desired mechanical properties it is known from German Patent No. DE 35 16 545 C2, the entire disclosure of which is hereby incorporated herein by reference, to manufacture the backside of a glove in certain areas out of two layers. A series of compression-proof bodies are arranged on a flexible, but non-yielding first layer (for example a suitable foil). A glove having such a backside can be easily bent, since the first, flexible layer does not provide any significant resistance against such a deformation. If the hand and the glove are extended, however, the compression-proof bodies of the second layer contact each other. The compression-proof bodies, together with the non-yielding nature of the first layer, prevent the backside of the glove from being bent in a direction of hyperextension, i.e., beyond the extended configuration.

Another approach is known from German Utility Model No. DE 201 13 431 U1, the entire disclosure of which is hereby incorporated herein by reference. A glove reinforcing element is disclosed comprising a plurality of hingedly connected parts, each of which have a rotation pin and at the other end a corresponding bearing cavity. The links are designed such that a rotation of two links is only possible in one direction and the link chain blocks a movement in the opposite direction beyond the extended configuration.

A further design is shown in German Patent Application No. DE 100 10 404 A1, the entire disclosure of which is hereby incorporated herein by reference. The glove reinforcing element disclosed in this document comprises a plurality of links that are threaded onto a pulling organ extending through the links. This arrangement is similar to the design of the backside of the glove disclosed in DE 35 16 545 C2, wherein the pulling organ, for example a wire, has the function of the first, non-yielding layer.

Glove reinforcing elements known from the prior art for active protection against hyperextension are, however, difficult to manufacture. For example, reinforcing elements made from a plurality of hingedly connected links first require each link to be manufactured. Subsequently, all links have to be interconnected. Since up to ten reinforcing elements are needed for a complete protection of the hands, this will lead to a significant manufacturing effort and resulting costs. As a consequence, gloves providing active protection against hyperextension are only found in high-priced gloves for (semi-) professional users. In particular, it is impossible to produce gloves with protection against hyperextension for children at a cost that would be accepted by the market, even though children have the greatest risk of injuries.

A further disadvantage is the comparatively greater weight of gloves having a backside as described in DE 35 16 545 C2. The same applies to gloves having other known reinforcing elements. As a result, the movements of the goalkeeper become slower and the wearer cannot react quickly to a surprise shot.

Furthermore, known glove reinforcing elements are typically uncomfortable and create pressure points on the backside of the finger and/or the hand, for example when a ball is deflected using the fist, so that a very high load acts locally on the reinforcing element. Glove manufacturers try to avoid this effect by providing complex cushioning; however, such complex cushioning further increases the price, renders the glove bulky, and leads to a less direct support function of the glove reinforcing element. Moreover, the use of a plurality of compression-proof bodies or hinges makes it difficult to control the ball when deflecting with the fist, so that the ball is often deflected in an uncontrolled manner.

In a completely different technical field, i.e., the manufacture of soccer boots, it is known from German Patent Application No. DE 27 32 463, the entire disclosure of which is hereby incorporated herein by reference, to integrate a curved reinforcing insert into the shoe sole, which allows a bending of the shoe during rolling-off, but which stabilizes the shoe when shooting a ball.

There is, therefore, a need to provide a reinforcing element that protects against hyperextension, overcomes at least some of the above mentioned disadvantages of the prior art, and can be manufactured at a low cost.

SUMMARY OF THE INVENTION

This problem is solved by a reinforcing element, in particular for a goalkeeper glove, that allows a bending in a first direction (e.g., gripping), but avoids a hyperextension of a joint of a wearer, in an opposite direction. The reinforcing element includes at least one bending area that corresponds to the wearer's joint when worn. The bending area has a curvature with a shape that allows bending in a first direction and blocks a bending in a second direction. Furthermore, the reinforcing element can include at least one blocking element arranged at the bending area.

A reinforcing element in accordance with the invention is based on a fundamentally different mechanical principle than the reinforcing elements used in the prior art. Instead of hingedly connected links or material layers with non-yielding or compression-proof elements, the uni-directional bendability is provided by a suitably shaped curvature of at least one bending area of the reinforcing element. In addition, the at least one blocking element reinforces the bending when the bending of the reinforcing element is blocked.

In a basic embodiment, a reinforcing element in accordance with the invention can be an elongate element having a gutter-shaped component; as such a shape allows bending of the reinforcing element in the direction of the open side of the gutter, but remains rigid when bending into the opposite direction, subject to material failure of the reinforcing element. A gutter-shaped curvature is only arched in one spatial direction and thus shows a curved line in a transverse cross-section (e.g., a part of a circular arc), whereas a longitudinal section through a gutter-shaped curvature shows no curve. Additional embodiments described herein are optional modifications of the basic embodiment for providing anisotropic bending properties of the reinforcing element by a suitably shaped curvature.

A reinforcing element in accordance with the invention can be significantly easier and more cost-efficiently produced than the above described constructions of the prior art. In one embodiment, a unitary part is used, which can be manufactured by injection molding a suitable plastic material. A complicated assembly of individual components is not necessary. Furthermore, a reinforcing element in accordance with the invention can be easily adapted to different sizes by, for example, using different injection molding tools.

In one aspect, the invention relates to a reinforcing element for an article of clothing configured for bending in a first direction and resisting bending in a second direction. The reinforcing element includes at least one elongate element, at least one bending area disposed along a portion of the at least one elongate element, and at least one blocking element arranged at the bending area. The bending area can include a curvature having a shape that allows a bending of the reinforcing element in the first direction and blocks a bending of the reinforcing element in the second direction.

In a particular embodiment, the bending area is arranged in the region of a joint of, for example, the finger and/or the wrist. Since a bent joint (e.g., wrist or finger joint) forms an upwardly curved outer surface, the reinforcing element can be reliably arranged so that its shape, curved in the same direction, is above or adjacent the joint to be protected without requiring further measures to assure that it remains in this position. The conformation between the shape of the backside of, for example, the finger and/or the hand and the reinforcing element, which is arranged thereon, avoids local pressure points as they occur with the canted reinforcing elements of the prior art. In the case of a glove reinforcing element, the reinforcing element includes a plurality of bending sections that correspond to a plurality of finger joints.

In various embodiments, the at least one bending area of the reinforcing element has a dome-shaped curvature, i.e., a curvature that is curved in more than one direction. Both a transverse cross-section and a longitudinal cross-section through a dome-shaped curvature lead to a curved cut line. In contrast to a gutter-shaped curvature, a dome-shaped curvature localizes the bending at a predefined position, i.e., along a line extending essentially through the center of the dome-shaped curvature. The bending area can be located in a region of the elongate element that corresponds to a joint of a wearer when worn. Furthermore, the reinforcing element can include a plurality of bending areas located in regions of the elongate element that correspond to a plurality of joints of a wearer when worn. The reinforcing element can further include a substantially rigid interconnection area disposed along a portion of the at least one elongate element adjacent to the at least one bending area. The rigid interconnection area can have a gutter-shaped curvature. In one embodiment, the interconnection area includes at least one stiffening element disposed thereon and configured to resist bending (i.e., avoid deformation). In contrast to the bending area, the rigid interconnection area remains substantially rigid in spite of its curvature, regardless in which direction the reinforcing element is bent. The curvature is also advantageous for securing the reinforcing element onto the backside of an area of the body, such as, for example, a finger or a hand.

In addition, the reinforcing element can be configured for use in a glove and have a length suitable to extend substantially from a backside of a wearer's hand to an end of a finger. The reinforcing element can extend beyond the end of the finger. In one embodiment, the reinforcing element can be made as a single piece. The reinforcing element can, however, be made by multi-component injection molding of at least two different plastic materials. For example, a plastic material can be used for the bending areas that has a different elasticity than the material used for the interconnection areas. The reinforcing element can include a suitable material and/or a suitable coating to enable sliding of the reinforcing element within a receptacle of the article of clothing. Reinforcing elements of the prior art are typically maintained in the correct position by permanent gluing or hook and loop type connections; however, by making the reinforcing element of the invention slidable within a receptacle of the article of clothing, the reinforcing element will substantially automatically slide to the correct position within the article of clothing as the joint is flexed.

Moreover, the reinforcing element can include a releasably mounted weight for attachment thereto. In one embodiment, the weight is disposed proximate an end of the reinforcing element. Additionally, the curvature of the at least one bending area can extend laterally around the sides of a wearer's joint. The substantially rigid interconnection area can also include a curvature that extends laterally around the sides of a wearer's body adjacent the joint. These lateral curvatures protect the joint and surrounding areas against injuries from the side, for example, as caused by the hard studs on a football boot of a player. One or both of the bending area and the substantially rigid interconnection area can include at least one aperture defined thereby. Such an aperture, or cut-out, further reduces the weight of the reinforcing element. In addition, the aperture(s) can selectively influence the bending properties in sections of the reinforcing element. The at least one elongate element of the reinforcing element can provide a restoring force when bent in the first direction.

Furthermore, the at least one blocking element can be releasably attached to the bending area and arranged on top of the at least one bending area; however, other arrangements adjacent to or below the bending area are also contemplated and within the scope of the invention. In one embodiment, the blocking element is detachably attached to the reinforcing element so that the blocking element can be exchanged. This is desirable when adjustment of the reinforcing element for different purposes is required, for example an adjustment to a particular load or force exerted on the reinforcing element. In one embodiment, the blocking element is a separate element. In one embodiment, the at least one blocking element has at least two parts arranged at the bending area and configured to blockingly contact each other when the bending area blocks a bending of the reinforcing element during bending into the second direction. The bending presses the two parts against each other, which provides a substantial, additional resistance to a hyperextension of the finger. Bending in the opposite direction, however, is allowed, because the two parts are turned away from each other. Additionally, a top surface of the at least one blocking element can have a dome shaped curvature.

In one embodiment, the reinforcing element including the at least one blocking element can be manufactured as a single piece. Alternatively, the reinforcing element and the at least one blocking element can be manufactured by multi-component injection molding using at least two different plastic materials. In one embodiment, the at least one blocking element is made of a different, for example harder, material than a material of the reinforcing element.

The at least one blocking element can be attached to the reinforcing element by different means, such as, for example, glue, rivets, welding (e.g., high-frequency), hook-and-loop type fasteners, or a clip mechanism. The reinforcing element can include at least one pin, where the at least one blocking element is configured for attachment to the reinforcing element via the at least one pin. If there is more than one blocking element, or if the blocking element comprises two or more separate parts, there may be more than one pin. The pin(s) can be located in the bending area. The blocking element can define a recess in a bottom surface thereof for receiving the at least one pin. In further embodiments, at least two pins are located on each side of a region of maximum bending of the bending area.

In another aspect, the invention relates to an article of clothing including the afore-mentioned reinforcing element. The article can include a glove and the reinforcing element can be removably disposed within a receptacle of the article of clothing. In one embodiment, the glove includes an element corresponding to a backside of a hand to which the at least one reinforcing element can be releasably attached. The element for the backside of the hand can include a plate to, for example, protect a surface of the backside of the hand against injuries. In one embodiment, the reinforcing element is attached to the element in a releasable manner. Such a glove protects not only against hyperextension, but also against injuries as they may be caused by, for example, the sharp edges of studs that may contact the hands of a goalkeeper during use.

These and other objects, along with advantages and features of the present invention herein disclosed, will become apparent through reference to the following description, the accompanying drawings, and the claims. Furthermore, it is to be understood that the features of the various embodiments described herein are not mutually exclusive and can exist in various combinations and permutations.

DETAILED DESCRIPTION

In the following, embodiments of a reinforcing element in accordance with the invention are further described with reference to a glove reinforcing element for a goalkeeper glove. It is, however, to be understood that the present invention can also be used for other types of gloves, for example gloves for snowboarding, or other articles of clothing for actions which involve a risk of hyperextension of the various joints, such as individual fingers, the thumb, the overall hand, the wrist, the elbow, the knee, the neck, and the like.

FIG. 1 presents a perspective view of a single reinforcing element 1. As can be seen, there are three, significantly upwardly curved (e.g., convex) bending areas 10 connected by two interconnecting areas 20. End areas 30 are located at the rear end and the front end of the reinforcing element 1.

As indicated by the dashed arrows 11 in FIG. 1, the bending areas 10 can each be elastically bent and allow a downwardly directed bending of the reinforcing element 1; however, they provide a substantial resistance (subject to material failure) in the case of bending into the opposite direction. The dotted lines 13 in FIG. 1 indicate approximately the buckling line when bending the corresponding bending area 10. It can be seen that these lines each extend approximately through the center of the substantially dome-like bending areas 10. The shape of the bending area 10, however, only roughly defines the location of the buckling line 13. Therefore, the position of the buckling line 13 can, within certain limits, adapt to the anatomical situation of the joint arranged therebelow (see finger 15 in FIG. 2A). The less dome-like the shape of the bending area 10 is, the greater the adaptability of the reinforcing element 1. In the case of an exclusively gutter-shaped curvature, the reinforcing element can be downwardly bent using the same force at any location along the bending area 10.

Interconnecting areas 20 are arranged between the bending areas 10. The interconnecting areas 20 also have a curvature; however, this curvature is typically fully gutter-shaped (i.e., substantially C-shaped in a transverse cross-section) and adapted to the contour of the backside of a finger in sections without joints.

For limiting the bendability of the reinforcing element 1 to the bending areas 10, the interconnecting areas 20 can each be provided with one or more ribs 21. As a result, these sections of the reinforcing element 1 are substantially rigid in spite of their curvature. This property can also be achieved in a different manner by, for example, manufacturing the interconnecting areas 20 from an inelastic material. As explained in further detail below, the reinforcing element 1 in one embodiment can be formed as a single piece; however, using suitable methods it can still be made from different materials. As an alternative to interconnecting areas 20 stiffened by the ribs 21, tube-shaped interconnecting areas 20 could be used to extend over the finger or other body part like a sleeve and, therefore, provide a high degree of stiffness without any further measures. Another possible embodiment uses only one or more reinforcing ribs 21, without a curved interconnecting surface.

In the embodiment shown in FIG. 1, the interconnecting areas 20 extend laterally around the finger (sides 17, see also FIG. 2A) and protect the finger, or other body part, against injuries, for example caused by contacting the hard studs on a football boot of a soccer player or the like. In the bending areas 10, the lateral extension 19 is slightly smaller to allow an easier bending.

The end areas 30 are substantially similar to the interconnecting areas 20; however, it is possible to provide fewer reinforcing ribs 21 on the end areas 30 as compared to the number of ribs 21 on the interconnecting areas 20 (e.g., one rib instead of three ribs, as shown in FIG. 1).

FIG. 2A shows pictorially where the reinforcing element 1 shown in FIG. 1 can be arranged relative to a wearer's finger if disposed inside a glove. As can be directly seen, the three bending areas 10 are arranged on top of the three joints of the finger to be protected, whereas the essentially rigid interconnecting areas 20 cover the straight finger bones extending between the joints. FIG. 2B shows the reinforcing element 1 in a bent configuration. As one can see, the elastic bending areas 10 are bent, whereas the substantially rigid interconnecting areas 20 are unchanged. Thus, the reinforcing element 1 adapts itself to the bent contour of the finger 15. As a result, the reinforcing element 1 has a shape on its inner side that substantially corresponds to the shape of the backside of the finger 15, so that it “latches” onto the backside of the finger 15 and, therefore, automatically moves into or maintains the correct position relative to the joint(s) to be protected.

To this end, it can be advantageous to manufacture the reinforcing element from a material that easily slides, within certain limits, inside a receptacle (e.g., a pocket) of the glove or other article of clothing. This can, for example, be achieved by coating the reinforcing element 1 with a friction-reducing material, such as the Teflon® (polytetrafluoroethylene (PTFE)) brand sold by DuPont, or a similar substance, and/or by coating an inside surface of the receptacle with such a friction reducing material. Besides coating the reinforcing element 1, it is also possible to compound Teflon® directly into the plastic material used for forming the reinforcing element 1. Other possible materials and manufacturing techniques are described in greater detail hereinbelow. Furthermore, an example of a support device disposed in a pocket on an article of clothing is described in U.S. Pat. No. 6,715,218, the entire disclosure of which is hereby incorporated herein by reference.

Additionally, the good fit of the reinforcing element 1 to the area to be protected due to the sequence of dome-shaped bending areas 10 and the gutter-shaped interconnecting areas 20 leads to a significantly improved wearing comfort compared to the reinforcing elements of the prior art with their hard, typically planar shaped links, which are not adapted to the positioning of the joints in the finger.

In one embodiment, the two end areas 30 extend slightly beyond a topmost end of the finger 15 to be protected and its rear end, respectively. This leads to additional protection for the finger 15 at its front end. For example, when a ball or the like hits the finger from the front side, the arising load is taken up directly by the reinforcing element 1. At the rear end, the extension of the end area 30 causes any hyperextension load to be securely transmitted from the reinforcing element 1 to the overall area of the hand.

FIGS. 2A and 2B show that the upwardly directed upper side (i.e., the outer side) of the reinforcing element 1 has a shape that corresponds substantially (apart from the ribs 21) to the contour of the unprotected finger. This feature facilitates the use of the upper side for deflecting a ball, for example by using the fist. In contrast to known reinforcing elements with a sequence of comparatively thick and hard elements having canted shapes and many edges, the reinforcing element 1 of FIGS. 2A and 2B more easily deflects the ball into a certain direction. If necessary, the stiffening ribs 21 can be covered by a second curved surface on the outside, thereby leading to an almost complete conformation with the typical shape of the backside of a finger, which will further improve control over a deflected ball.

FIG. 3 illustrates an additional weight 40 that can be disposed proximate the end area 30 of the reinforcing element 1. The weight 40 can influence the dynamic properties of the article of clothing and, thus, the movements of the wearer. For example, an increased weight at the finger tips leads, due to the arising centrifugal force, automatically to a maximally extended hand configuration when the goalkeeper quickly raises his arms so that he covers the maximum area with his hands.

The weight 40 can be attached to the reinforcing elements in different ways, for example by clipping, screwing, lateral insertion, or other releasable mounting techniques that allow replacement of the weight for another weight of a different mass or to use the reinforcing element 1 without the weight 40. It is, however, also possible to permanently integrate the weight 40 into the receiving element 1. Apart from the arrangement at or in the end area 30, the weight 40 can also be arranged at any other section of the reinforcing element 1. In addition, it is possible to use different weights for different body parts.

FIGS. 4 and 5 illustrate how one embodiment of the reinforcing element 1 can be integrated into a complete protection system inside a glove. To this end, there is for each finger and, if necessary, the thumb a reinforcing element 1 that is releasably connected with a plate 50 for the backside of the hand. As already mentioned with respect to the additional weight 40, a number of known attaching methods are suitable for attaching the reinforcing elements 1 to the plate 50. It is desirable for the interconnection to be sufficiently stable to securely transmit the arising loads on an individual reinforcing element 1 into the plate 50 for the backside of the hand. In the embodiment shown in FIGS. 4 and 5, the reinforcing elements 1 are inserted from the front into receptacles 52 that are on their top side closed by a reinforcing ridge 53 that may, if necessary, be provided with suitable latching means. The contact between the rear end area 30 and the receptacle 52 includes a form fit and, thereby, provides the desired stability.

The plate 50 for the backside of the hand may cover substantially the entire backside of the hand and additionally protect the hand from injury from, for example, a player stepping with a studded shoe onto the flat hand of the goalkeeper. As can be seen in the side view of FIG. 5, the plate 50 for the backside of the hand also laterally encompasses the hand (sides 29) in its rear part to provide a good fit and to extend the protection onto the side regions of the hand. The plate 50 may also include a bending area with a curvature in its rear part to protect the wearer's wrist against hyperextension in a similar manner as an individual reinforcing element 1 protects the finger joints.

The reinforcing element 1 can be manufactured as a single plastic part by injection molding or extrusion. Both methods lead to very low manufacturing costs, a low weight, easy adaptation to different sizes, for example for children's gloves, by using correspondingly adapted molds for injection molding. In some embodiments, the single piece reinforcing element can be manufactured by multi-component injection molding more than one plastic material. For example, a harder plastic material can be used for the interconnecting areas 20 and a particularly soft and elastic plastic material can be used for the bending areas 10 to provide a lower bending resistance, in particular for children's gloves. The multi-component injection molding may be performed simultaneously using one or more nozzles or sequentially. Alternatively, the plastic material can be injected around separately pre-manufactured components of the reinforcing element 1. For example, interconnecting areas 20 made from a sufficiently hard material (for example a metal or a composite material including carbon fiber) may be encompassed by a soft plastic material forming the bending areas 10.

Suitable plastic materials include: thermoplastic polyurethanes (TPU); polypropylene (PP); ethylene vinyl acetate (EVA); thermoplastic polyether block amides, such as the Pebax® brand sold by Elf Atochem; thermoplastic polyester elastomers, such as the Hytrel® brand sold by DuPont; thermoplastic elastomers, such as the Santoprene® brand sold by Advanced Elastomer Systems, L.P.; thermoplastic olefin; nylons, such as nylon 12, which may include 10 to 30 percent or more glass fiber reinforcement; silicones; polyethylenes; acetal; and equivalent materials. Reinforcement, if used, may be by inclusion of glass or carbon graphite fibers or para-aramid fibers, such as the Kevlar® brand sold by DuPont, or other similar method. Also, the polymeric materials may be used in combination with other materials, for example natural or synthetic rubber. Other suitable materials will be apparent to those skilled in the art.

The use of shape memory materials is also possible. Shape memory materials can be brought back into an initial state by applying heat or the like, if the supporting function decreases after some time of use. The very cost efficient manufacture by injection molding, however, allows the reinforcing elements to be used as wearing parts. Reinforcing elements that are permanently bent or no longer sufficiently stable can simply be replaced.

Finally, it is also possible to modify the above explained embodiments by selectively arranging apertures or cut-outs (27 in FIG. 3) in sections of the reinforcing element 1. The cut-outs 27 can influence the bending properties (for example, a notch 27′ disposed on a side of a bending area 10 will influence the bending resistance of the reinforcing element) and reduce the overall weight of the reinforcing element 1. The arrangement of cut-outs 27 as well as the material selection and the exact shape of the reinforcing element 1 can vary to suit a particular application and can easily be optimized using a finite-element-analysis. While typically elongate in shape, the reinforcing element 1 can have essentially any shape, such as polygonal, arcuate, or combinations thereof, and will be sized based, at least in part, on the area of the body to be protected and the relative size of the wearer.

In a particular embodiment, the reinforcing element 1 can be arranged in an article of clothing in a detachable manner, which results in a plurality of individual adaptation possibilities. For example, stiffer glove reinforcing elements can be exchanged for softer glove reinforcing elements if a goalkeeper prefers less bending resistance. Besides an individual adaptation of the length, width variations are possible to comply with different body part thicknesses. Additionally, a color adaptation for optical aspects is possible if the reinforcing elements are arranged in transparent pockets on the article of clothing. For example, the reinforcing elements can correspond to certain team or logo colors. Additionally, color coding can be used to denote reinforcing elements with differing properties, e.g., hardness. Moreover, the releasable arrangement allows the wearer to replace damaged or insufficiently stiff reinforcing elements immediately (e.g., during a game).

FIG. 6 depicts a reinforcing element 1 according to an alternative embodiment of the invention. As can be seen, the reinforcing element 1 includes an additional blocking element 60 arranged in the bending area 10. The blocking element 60 allows bending of the reinforcing element 1 in a first direction (indicated by the dashed arrows 11 in FIG. 1) and reinforces the bending area 10 when bending into a second direction (the direction opposite to the dashed arrows 11 in FIG. 1) is blocked. As a result, the maximum load or force that can be blocked is increased.

In one embodiment, the blocking element 60 is arranged on top of the bending area 10. Alternatively, the blocking element 60 may be arranged in other suitable regions of the bending area 10. The blocking element 60 may cover a part of the bending area 10 or it may cover the whole bending area 10. Furthermore, the blocking element 60 may extend into the interconnecting region 20 and may also extend from one bending area 10 to another bending area 10.

As can also be seen in FIG. 6, the blocking element 60 can include two parts 61, 62. When the reinforcing element 1 is bent into the second direction, the two parts 61, 62 blockingly contact each so that a further bending is blocked. The bending presses the two parts 61, 62 against each other, which provides a substantial, additional resistance against a hyperextension of the protected joint. Bending in the first direction is, however, allowed because the two parts 61, 62 are turned away from each other.

In the embodiment of FIG. 6, the two parts 61, 62 are separated by a gap 63 in an initial configuration of the reinforcing element 1 (i.e., without bending). The size and shape of the gap 63 may vary to suit a particular application and, in one embodiment, may become infinitely small. The two parts 61, 62 may also be in direct contact with each other. Further, the two parts 61, 62 may be arranged in such a way that they pre-bend the reinforcing element 1 in the first direction (i.e., the gripping direction).

Alternatively, the blocking element 60 may include more than two parts. In still another embodiment, the blocking element 60 is a single piece that is adapted to allow bending of the reinforcing element 1 in the first direction and to block bending in the second direction.

As also illustrated in FIG. 6, the blocking element 60 includes a dome-shaped curvature. In this way, the blocking element 60 is adjusted to the overall shape of the reinforcing element 1, which reduces the risk of injuries of other players and improves control when deflecting a ball.

The blocking element 60 and the reinforcing element 1 can be integrally manufactured during a single injection molding process. In one embodiment, the same material is used for both elements. Alternatively, the manufacture of the blocking element 60 and the reinforcing element 1 may use co-injection of different materials with one or two molds. In this case, the blocking element 60 may be made from a harder material than the reinforcing element 1 in order to increase the reinforcement of the bending area 10.

FIG. 7 is a side view of the reinforcing element 1 of FIG. 6. FIG. 7 clearly shows the gap 63 between the two parts 61, 62 of the blocking element 60 in the initial configuration of the reinforcing element 1. As already mentioned above, the gap 63 may become infinitely small, or the two parts 61, 62 may directly contact each other. This figure also shows the above mentioned dome shaped curvature of the blocking element 60, which is different at its top side and its bottom side.

FIG. 8 is a front view of the reinforcing element of FIG. 6. The dome-shaped curvature of the blocking element 60 can also be seen in this direction.

A further embodiment of the invention is illustrated in FIG. 9, where the blocking element 60 is a separate element that is attached to the reinforcing element 1. The use of a separate element provides various advantages, such as the use of specifically adapted materials and the possibility to exchange blocking elements 60, which is described in more detail below.

The blocking element 60 may be attached to the reinforcing element 1 by different means, such as, for example, glue, rivets, hook-and-loop type fasteners, or a clip mechanism. In the embodiment illustrated in FIG. 9, the reinforcing element 1 includes pins 91 on which the blocking element 60 is located. The pins 91 may be located in the bending area 10 or in any other area to which the blocking element 60 extends. In one embodiment, the pins 91 are an integral part of the reinforcing element 1. Alternatively, the pins 91 can be located on the blocking element 60, with the reinforcing element 1 having corresponding holes.

In the embodiment of FIG. 9, a pair of pins 91 is located on each side of a region of maximum bending of the bending area 10. The blocking element 60 is placed on the two pairs of pins 91. This arrangement of the pins 91 can also be seen in FIG. 10; however, without the blocking element 60. As an alternative to the attachment of the blocking element 60 to the reinforcing element 1 with four pins 91, a fewer or greater number of pins 91 may be used.

The at least one blocking element 60 may be manufactured from the same material as the reinforcing element 1, as described hereinabove. Alternatively, the blocking element 60 can be manufactured from a different material, for example a harder one including metals or composite materials. In another embodiment, the blocking element 60 itself is made of more than one material. For example, the blocking element 60 may have a hard bottom layer to maximize reinforcement of the bending area 10 and a soft top layer, in order to minimize an impact to other objects contacted by the reinforcing element 1 during use. In one embodiment, the blocking element 60 and the reinforcing element 1 are made from plastic material so that they can be permanently attached to each other by heating and pressing.

Alternatively, the blocking element 60 can be detachably attached to the reinforcing element 1 so that the blocking element 60 can be exchanged. This is useful when an adjustment of the reinforcing element 1 to a different purpose is required, for example an adjustment to a particular load or force exerted on the reinforcing element 1. To this end, blocking elements 60 with different mechanical properties may be used. Moreover, detachable blocking elements 60 enable the use of materials for blocking elements 60 with particular mechanical properties, but which wear-out after some use so that they need replacement. For example, a goalkeeper may prefer to use harder blocking elements during training in order to improve protection of his fingers. On the other hand, during a game he may prefer softer blocking elements that provide a better feeling for the ball.

FIG. 11 is a perspective view of a blocking element 60 according to one embodiment of the invention. As can be seen, the blocking element 60 has two parts 61, 62. Moreover, the blocking element 60 includes holes 121 corresponding to pins 91 of the reinforcing element 1. FIG. 11 also illustrates that the top surface of the blocking element 60 has a dome-shaped curvature.

FIG. 12 is the corresponding bottom view of the blocking element 60 of FIG. 11. As can be seen, the bottom side of the blocking element 60 also has a dome-shaped curvature. In a particular embodiment, the bottom side of the blocking element 60 and the bending area 10 of the reinforcing element 1 have substantially the same dome-shaped curvature, which facilitates the attachment of the two. As can be seen in FIG. 12, the blocking elements 60 could include indentations 132 on the bottom side of the blocking elements, whereby the indentations correspond to ribs 21 on the reinforcing element 1 that extend into the bending area 10.

FIG. 12 also shows a recess 131 in the middle of the bottom side of the blocking element 60. As explained above, the bending area 10 obtains a different shape during bending, in particular along a centerline of the bending area 10. The recess 131 provides a space into which the bending area 10 can extend. Therefore, the recess 131 facilitates bending of the bending area 10. Moreover, it avoids stress on the blocking element 60, which may cause detachment of the blocking element 60.

The recess 131 is also illustrated in FIG. 13, which is a close-up perspective view of the bending area 10 of the reinforcing element 1. As can be seen, the recess 131 leaves a space between the bending area 10 and the bottom side of the blocking element 60. In this view, the reinforcing element 1 is not bent. As explained, the bending area 10 gradually extends into the recess 131 during bending. FIG. 13 illustrates different curvatures in the longitudinal direction and the transversal direction and on the top side and the bottom side of the blocking element 60.

As can also be seen in FIG. 13, the pins 91 may extend out of the at least one blocking element 60. Once the at least one blocking element 60 has been placed on a pin 91, the end of the pin 91 may be heated, for example by ultrasonic welding, and pressed downwardly. Subsequently, the hot plastic material of the pins deforms and prevents removal of the blocking element. In one application, the heated plastic material of the pin 91 is squeezed into the recess provided by the conical expansion on the top of the holes 121 for the pins 91, which can be seen in FIG. 11. This would then lead to a fixation of the at least one blocking element 60 on the reinforcing element 1, where the top surface of the blocking element 60 and the top surface of the pin 91 may be flush in a final state.

Having described certain embodiments of the invention, it will be apparent to those of ordinary skill in the art that other embodiments incorporating the concepts disclosed herein may be used without departing from the spirit and scope of the invention. The described embodiments are to be considered in all respects as only illustrative and not restrictive.
