DETAILED DESCRIPTION
[0101] Referring to
[0102] In aspects, the elongated tubular body 21 is formed or molded from plastic material, so as to provide in certain areas thereof, flexible sections, while also affording rigidity and strength to the overall tubular body 21.
[0103] In aspects, when the gripping device 24 is cut lengthwise on one side, it forms a longitudinal opening 46 having opposed edges 48 and 50. In aspects, the gripping device 24 can be attached to a seat tube 22 by drawing the edges 48 and 50 apart and the backing sheet 34 is removed to expose the adhesive layer 32 for pressure application to the surface of the seat tube 22. In this way, the opposed edges 48 and 50 can expand over the seat tube 22 and thereafter collapse or return back to unexpanded tubular body shape as shown in
[0104] In aspects, the gripping device 24 may be produced in a tubular form, such as, an elongated cylindrical/tubular component 21. In aspects, the gripping device 24 can be cut longitudinally to make for the proper reception on the seat tube 22 of the bicycle.
[0105] In aspects, the griping device 24 can be placed on a seat/saddle tube 22 by first providing a gripping device 21 for placement on the seat tube 22.
[0106] In aspects, the outer layer 40 is formed of a plastic material in a radial or extended state.
[0107] In aspects, the outer layer 40 is configured to provide a secure and comfortable hold on the seat tube 22 for a user.
[0108] In aspects, the inner layer 26 can be applied in a fashion to allow the outer layer 40 to maintain a proper grip.
[0109] Advantageously, when the gripping device 24 is cylindrical in shape it accommodates a person's hand grasping the particular part of the bicycle frame which would normally be situated immediately above the area of the front derailleur on the seat tube 22 of the frame.
[0110] It is contemplated that the gripping device 24 is not limited in its use to any particular part of the bicycle frame alone. It can also be placed on the top tube in very close approximation to the seat post an area that might be shown to contain a seat post clamp. In this position it would be used as a shoulder pad for an individual who might want to manually carry his bicycle (in a form that would be akin to the portaging manoeuvre normally associated with canoeing). The bicycle would be perched high on his shoulder while he supports the rest of the bicycle with his free hands.
[0111] It is contemplated that the gripping device 24 can be placed on the down tube of the bicycle frame in order to manually lift and carry the bicycle. In an illustrative fashion it would be demonstrated how the top tube can be rested on the user's shoulders. This procedure would involve grasping the down tube with one hand whilst the other hand can be placed on the seat tube gripping device 24.
[0112] In aspects, the outer layer 40 is formed from a softer material for comfort, but not at the expense of durability. It is contemplated that this outer layer 40 is such that it resists abrasion and is highly flexible. In aspects, a lightweight closed cell polyethylene foam or the like can be used for the outer layer 40 and/or the inner layer 26. In aspects, this material has a nonslip surface which improves control and safety, provides tear/tensile durability and resiliency to abuse and is particularly weather resistant. In this way, when the inner layer 26 is made of polyethylene material, the gripping device 24 may have improved slip-resistance when placed about the seat tube 22. In aspects, the outer layer 40 will have a Shore A Durometer coefficient reading in the range of about 35 to 75, typically less than 60, which is ideally suited to provide for the best human interactive factor.
[0113] In aspects, the inner layer 26, or substrate portion, is factory fitted (a process referred to as injection moulding), to the outer layer 40 providing for a fixed attachment. In aspects another technique including an adhesive layer 32 formed from a mastic material can be used. The aforementioned inner layer 26 can be made from a material of substantially greater rigidity, having a Shore A Durometer coefficient reading of 87. In this way, the substrate portion can create the sensation of concentrating the pressure of a user's grasp against the bicycle's frame.
[0114] The process of injection molding is known in the art. In aspects, the injection molding process can be bi-injection molding, co-injection molding or overmolding.
[0115] In aspects, the inner layer 26 may be laminated to the outer layer 40 by any suitable technique known in the art, such as by vulcanizing, flame laminating or with an adhesive.
[0116] Advantageously, the gripping device 24 is moulded from a plastic material with a high coefficient of friction while at the same time allowing for a safe hand grip. The plastic material used in the moulding of the gripping device 24 provides a good feel to the touch, and good friction with the hands skin. In addition, it provides adequate support after a fashion that will allow the user to loosen the tension of his or her grip without actually having to diminish or otherwise compromise his or her grip when manually lifting the bicycle.
[0117]
[0118] In aspects, the sheet members 27 and 29 are longitudinally abutted against one another around the periphery of the seat tube 22.
[0119] In aspects, the sheet members 27 and 29 are arranged in an appositional manner, with the location of the edges of the outer 40 and inner 26 sleeves being juxtaposed. Advantageously, this arrangement would not only guarantee the structural integrity of the gripping device 24, but ensures remarkable comfort to the user's hand.
[0120] In aspects, the outer 40 and inner 26 layers of the gripping device 24 are made of differing materials. In aspects, the outer 40 and inner 26 layers are made of the same material.
[0121] As shown in
[0122] In aspects, the adhesive 32 is a pressure sensitive adhesive. A suitable adhesive is a medical grade adhesive rubber. In preferred embodiments, the adhesive has at least a limited degree of stretchability to provide the ultimate control over the actual warpage and shaping of the device 24 around the seat tube 22.
[0123] In aspects, after the sandwiched structure 30 has been cut to the desired size, based on, but not limited to the dimensions of the bicycle, the backing sheet 34 can be removed by, for example, peeling. Once the backing sheet 34 is removed, the remainder of the sandwiched structure, now cut to size, can be properly aligned with a portion of the seat tube 22, such as, a center line of the seat tube 22, and then rolled (as indicated by arrows 35) onto the peripheral surface of the seat tube 22 causing it to adhere to the seat tube 22 by reason of the adhesive layer 32. When fully mounted, opposed edges 36, 38 (
[0124] In aspects, the foam pad 26 of the sandwiched structure 30 may receive an overlying, contiguous, resilient pad 40 of rubber-like material. In aspects, the pad 40 would preferably be of a tougher but less resilient material than that of the foam pad 26. Advantageously, rubber-like pad 40 can improve the durability of the sandwiched structure 30. In aspects, the rubber-like pad 40 would be substantially more wear resistant than the foam pad 26. In addition, the resilient layer of rubber-like material 40 may overlie the pad to extend the life of the foam pad 26.
[0125] Turning to
[0126] In some embodiments the described device 24 is secured in place by the use of fastening elements that are secured to the flexible gripping surface and configured to engage cooperatively when the gripping device is wrapped around the seat tube 22 of the bicycle frame.
[0127] Advantageously, the semi-permanent construction allows for periodic removal of the foam pad 40 when it has been worn to an extent that it no longer serves its intended function. In this way, it may be replaced with a new foam pad. As in the instance of the sandwiched structure 30, the modified sandwiched structure 30A may also provide for a rubber-like sleeve 40 overlying the foam pad 26.
[0128] As seen in
[0129] Because the seat tubes 22 of a bicycles may be of a wide variety of sizes, shapes, and even cross sections (for example, round, oval, oblong and the like), it is contemplated that the sandwiched structure 30 has both a nominal size which, when so desired, can be cut to a final desired size at which point it should become necessary to apply it to a seat tube 22. For example, the final gripping device may have a diameter from about 40 mm to about 48 mm, depending upon the diameter of the seat tube 22. In specific embodiments the outer diameter of the outer layer 40 of the gripping device 24, 24B is 40.6 mm or 41.8 mm or 43.8 mm or 46.9 mm or 48.4 mm.
[0130] Typically, the pad 26 would be supplied with specific part numbers to represent the actual periphery and configuration for that particular model of the bicycle.
[0131] As diagrammatically depicted in
[0132] As shown in
[0133] In aspects, these alternating recesses 42 and ridges 20 are meant to conform to the locations of fingers and spaces, respectively, not unlike that between the fingers of a user's hand. Thus, the fingers of a user's hand may comfortably rest within the recesses 42 while the ridges 20 generally conform to and are positioned in the spaces between the fingers of a user's hand
[0134] In aspects, when the gripping device 24B is mounted on the seat tube 22 as herein described, it may be necessary to rotate the tubular body 24B relative to the seat tube 22 to position the recesses 42 and ridges 20 for gripping by the user.
[0135] Advantageously, when the gripping device 24B is fitted on the seat tube 22, the device 24B assumes the same shape generally of the cylindrical body to which it is attached and the recesses 42 and ridges 20 allow for bonding with the location of, and the shape of the fingers of the user.
[0136] In aspects, the recesses 42 are positioned opposite the opening 46 of the tubular body 24B. In aspects, the recesses 42 and ridges 20 may be formed when the opposite edges 36 and 38 of the device 24B are brought together and collapse about the seat tube 22.
[0137] As shown in
[0138] In aspects, the gripping device 24B automatically aligns itself with a longitudinal axis of the seat tube 22.
[0139]
[0140] As shown in
[0141] The seam member 56 comprises a planar body 60 and a projecting ridge 62, extending along a surface of a planar body (see
[0142] While
[0143] It is contemplated that the gripping device 24B can be made by any known method in the art. For example, the gripping device 24B can be made using the method involving a process referred to as injection moulding which is the most frequently used technique for manufacturing parts made of thermoplastic materials [TPEs].
[0144] In aspects, a soft feel texture can be achieved by using a soft material that might have a hardness that is less than 60 Shore A and a thickness of at least 1.5 mm. Typically the thickness would be from 1.5-2.0 mm. In this instance both the soft material and the hard substrate can be felt when grasping the gripping device 24 or 24B. By soft feel it is meant to imply a material that is malleable having little resistance to pressure, a perception normally learnt by touching or being aware through the senses, having a particular effect conveyed by the sense of touch. This can be a layer of foam that imparts a soft textured feel very similar to that obtained from cork like material, velvety foam or open cellular foam rubber (thermoplastic elastomeric), a material which is compliant and soft feeling, or anything that equates to a soft touch which gives the sample a tactile feel.
[0145] Aesthetics play a large role in the design of the gripping device 24 and 24B. Common issues regarding the appearance of any device are colour, surface finish, uniformity and texture. This can be achieved by creating a unit in which the soft grip will be a different colour to the rigid substrate portion.
[0146] Advantageously, the present invention provides for a cushioned gripping device 24 or 24B for selective attachment to the seat tube 22 of a bicycle. In particular, it serves to improve the ability of a person to maintain their grip on the bicycle frame while manually lifting the same, and at the same time cushioning the user's hand and providing protection against abrasion.
[0147] Advantageously, by use of the present invention (when applied to, for example, the bicycle seat tube 22), a cyclist, who might have been riding for an extended period of time, especially in hot and humid weather, now has a suitable gripping device 24 and 24B that allows for the cyclist to grip and manually lift the bicycle without fear of losing control because of sweat on the hands (sweaty palms). A condition which might result in the user losing his or her grip on the bicycle frame/seat tube 22. Accordingly, this will avert any possibility of injury caused by the bicycle inadvertently colliding with the cyclist. Given the frequency of life's unguarded moments and the attendant bodily discomforts so often brought on at these seemingly inopportune moments, the user can rest assured there would be no need to exert increased energy to control the bicycle while attempting to manually lift and transport it.
[0148] Advantageously, the gripping device 24 and 24B of the present invention is intended to provide the bicycle user the added comfort and a higher degree of ease not otherwise possible when manually lifting the bicycle. Hence no longer would the user need to apply or assert the force that until now would have required a much firmer grasp by one's hand to the bare metal frame of the bicycle.
