[0001] DISPOSABLE ACCESSORY FOR DISPENSING LUBRICANT ONTO A CHAIN, DEVICE AND KIT COMPRISING SUCH AN ACCESSORY AND USE METHOD THEREOF

[0002] DESCRIPTION

[0003] Field of the invention

[0004] The present invention generally relates to the technical field of maintenance of machines or motorcycles equipped with a chain drive, and it particularly relates to an accessory for distributing a lubricant on the chain.

[0005] The invention also relates to a device which comprises such accessory.

[0006] State of the Art

[0007] In general, there is known the need to lubricate the chain drives, that is to distribute the lubricant on the chains, whether they are chains of motorcycles, bicycles or industrial machines.

[0008] The prior art devices for distributing lubricants are of the dispensing or dispenser type, that is they consist of spray cans, generally provided with a straw to direct the lubricant toward the chain.

[0009] Motorcycle and bicycle chains, especially if subjected to heavy use such as off-road and / or racing, require frequent lubrication. Therefore, users perform such operation in the personal spaces available such as garages, basements, streets or the like.

[0010] A known drawback lies in the fact that most of the lubricant drops on the ground and in any case it is not evenly distributed over the chain.

[0011] Therefore, often the user is forced to abound. If high quality lubricants are used, this operation results in obvious waste of material with significant economic burden. In addition, in this case, drops will form on the chain which will then be dispersed at the first use, soiling the environment and the user.

[0012] Another drawback of prior art dispensing devices lies in the fact that it does not allow to effectively re-use the device.

[0013] These drawbacks are particularly evident in view of the fact that this lubrication operation must be repeated frequently even by non-professional users.

[0014] Summary of the invention

[0015] An object of the present invention is to at least partly overcome the aforementioned drawbacks, by providing an accessory for distributing for lubricant that is highly functional and cost-effective.

[0016] A further object of the invention is to provide an accessory for distributing lubricant that allows to distribute the lubricant effectively on the chain.

[0017] Another object of the invention is to provide an accessory for distributing lubricant that ensures that the correct amount of lubricant is dispensed.

[0018] Another object of the invention is to provide an accessory for distributing lubricant that is particularly suitable for the bicycle chain.

[0019] A further object of the invention is to provide an accessory for distributing lubricant that is particularly suitable for the motorcycle chain.

[0020] A further object of the invention is to provide an accessory for distributing lubricant that prevents the user from dirtying himself.

[0021] Another object of the invention is to provide a device for distributing lubricant that is highly functional and cost-effective.

[0022] Another object of the invention is to provide a reusable device for distributing lubricant.

[0023] Another object of the invention is to provide a reusable kit for distributing lubricant.

[0024] Another object of the invention is to provide a method for using the accessory and the device for distributing lubricant that is highly functional and cost-effective.

[0035] Detailed description of some preferred embodiments

[0036] With reference to the mentioned figures, herein described is a device 1 for distributing a lubricant on a chain C of a bicycle or motorcycle.

[0037] The lubricant may be of different type depending on the needs. For example it may be oil, grease or a specific mixture prepared specifically.

[0038] Suitably, the device 1 may comprise a container 105 for the lubricant.

[0039] Depending on the configuration, the device 1 may comprise a dispenser 100, for example in the form of a pressure can, or an injector 100', for example in the form of a manually operated syringe.

[0040] The dispenser 100 does not allow to control the amount of lubricant dispensed, but has the advantage of ease of use. On the other hand, the injector 100' allows to precisely control the amount of lubricant dispensed.

[0041] Suitably, the injector 100' may comprise a transparent portion at the container 105 so as to allow the user to check the amount of lubricant contained and / or injected. Suitably, there may be provided for a graduated scale.

[0042] Preferably, the dispenser 100 and the injector 100' may comprise the container 105, an outlet 101 for the lubricant fluidically connected with the container 105 and means 110 for promoting the outflow of the lubricant from the container 105 through the outlet 101.

[0043] According to an embodiment, the injector 101 may generally be in the form a syringe, for example as shown in FIG. 3 and FIG. 5.

[0044] The syringe may be of the per se known type and it may comprise a cartridge, a plunger and a nozzle.

[0045] In this case, the tubular cartridge may define the container 105 for the lubricant, the nozzle may define the outlet 101 and the plunger may define the means 110.

[0046] Such configuration may be particularly economic.

[0047] Furthermore, such configuration may allow a high control of the dispensed amount of lubricant. Such aspect may be particularly suitable should the user be an amateur or in the case of use with outdated means that require particular expertise.

[0048] Possibly, the injector 100' may be of the disposable type. Possibly, also the volume of the container 105 may be equal to the correct amount of a single use.

[0049] In this manner, the user may use the device 1 easily.

[0050] On the other hand, according to a different embodiment, for example as shown in FIG. 1, the dispenser 100 may comprise a pressure can with an outlet 101 that can be selectively opened / closed by means of valve means which can be actuated by a user.

[0051] In this case, the can may define the container 105 for the lubricant and the valve means may define the dispensing means 110.

[0052] Such configuration may make the use of the device 1 particularly simple and quick. Furthermore, such configuration may be particularly adapted for dispensing the lubricant when the chain C moves at a high speed.

[0053] Irrespective of the configuration, the device 1 may preferably, but not exclusively be of the disposable type.

[0054] Thanks to this characteristic, the user may distribute the correct amount of lubricant on the chain.

[0055] Furthermore, this may advantageously allow the user to avoid having to store the device 1 already used preventing the lubricant from flowing out of the container 105.

[0056] In order to allow an effective distribution of the lubricant, the device 1 may comprise a dispensing accessory 10. Suitably, the accessory 10 may be suitable to be selectively coupled with the dispenser 100 or the injector 100'.

[0057] Preferably, the outlet 101 and the accessory 10 may be mutually fluidically connected, as better explained hereinafter.

[0058] During use, the accessory 10 and the chain C may slide mutually. For example, the chain C may be moved while maintaining the accessory 10 stationary or vice versa. In other words, as better explained hereinafter, the accessory 10 may be configured to distribute the lubricant on the chain C.

[0059] Essentially, the accessory 10 may comprise an inlet 11 for the lubricant which may be fluidically connected with the outlet 101 of the dispenser 100 or injector 100'.

[0060] The accessory 10 may further comprise an outlet 12 for the lubricant.

[0061] Suitably, there may be provided for a duct 13 for fluidically connecting the inlet 11 and the outlet 12.

[0062] The accessory may therefore comprise or consist of a support structure 10'.

[0063] The support structure 10' may internally include the duct 13.

[0064] Preferably, the support structure 10' may have a substantially longitudinal extension along an axis X. Preferably, but not exclusively, the duct 13 may extend substantially parallel to or coincident with such axis X.

[0065] The support structure 10' may comprise a portion 20 and a portion 30.

[0066] The portion 20 may have a substantially tubular extension and it may preferably be coaxial to the axis X.

[0067] The operative portion 20 may be designed to be coupled with the dispenser 100 or injector 100', preferably at the outlet 101.

[0068] Suitably, the portion 20 may have a coupling area 21 designed to be coupled with a corresponding portion 121 of the dispenser 100 or injector 100'.

[0069] Once the portions 21 and 121 are coupled, the outlet 101 may be fluidically connected with the inlet 11.

[0070] The outlet 101 and the inlet 11 may be in proximity, preferably they may coincide. Should the dispenser 100 comprise a straw, the portion 121 may be the terminal part of the straw.

[0071] Suitably, although not shown in the figures, the dispenser 100 or injector 100' may comprise extensions such as the straight tubular straw shown in FIG. 1 in FIG. 2. In this case, the outlet 101 may be the end of the straw and the coupling portion 121 may be the outer wall of the straw in proximity of the end of the outlet 101. It is clear that the straw may be removable and / or replaceable. Possibly, there may be provided for extensions or adapters having any shape, for example straight, curvilinear, flexible or stiff, or even angular-shaped. Upon coupling the extensions with the dispenser 100 or injector 100', the outlet of the extension may define the outlet 101.

[0072] Possibly, the extensions may be coupled with the dispenser 100 or injector 100' or they may be an integral part thereof.

[0073] The extensions may preferably be of the disposable type.

[0074] According to a preferred embodiment, the coupling area 21 may be substantially cylindrical-shaped, for example as shown in the embodiments of FIG. 8, FIG. 14, FIG. 18, which may be designed to be coupled with a corresponding cylindrical portion 121 of dispenser 100 or injector 100'. For example, such coupling may for example be obtained by interference.

[0075] On the other hand, according to a different embodiment, for example as shown in the embodiments of FIG. 10, FIG. 12, FIG. 16, coupling area 21 and the portion 121 may be mutually configured to form a Luer-lock coupling.

[0076] In greater detail, the area 21 may comprise an external thread 21' while the portion 121 may comprise a corresponding peripheral thread with respect to the outlet nozzle 101. In this manner, upon coupling the area 21 and the portion 121, the outlet 101 may be fluidically connected with the inlet 11.

[0077] Thanks to these couplings, the accessory 10 can be easily coupled / de-coupled with / from the dispenser 100 or injector 100'.

[0078] This may allow to change the accessory 10 without changing the dispenser 100 or the injector 100'.

[0079] Advantageously, should the dispenser 100 or injector 100' be a multi-purpose dispenser, the same dispenser 100 or injector 100' can be used repeatedly without the previously used accessory 10 contaminating or damaging the chain C due to residues.

[0080] A further advantage of the device 1 with dispenser 100 or injector 100' and removably couplable accessory 10 is to allow low production costs since it is possible to obtain devices 1 for different uses using the same dispenser 100 or injector 100' and different accessories 10. Regardless of the configuration of portion 20, operative portion 30 may be designed to interact with the chain C.

[0081] Preferably, the portion 30 may be on the opposite side with respect to the portion 20. Suitably, the accessory 10 may have a substantially longitudinal extension along the axis X in which portions 20 and 30 are on opposite sides.

[0082] Preferably, the portion 20 may have a substantially tubular extension and it may preferably be coaxial to the axis X.

[0083] Suitably, the operative portion 30 may comprise lubricant distribution means 40 designed to interact with the chain C.

[0084] These means 40 may comprise bristles 41 so as to define a brush or they may a spatula 42. The spatula 42 may be a planar element made of polymeric material. The spatula 42 may be rigid or slightly flexible.

[0085] Preferably, the entire accessory 10 may be made of polymeric material, preferably polyamide. Possibly, the bristles may be made of a different material.

[0086] Preferably, the outlet 12 may be arranged at the means 40 so that the lubricant flowing out from outlet 12 intercepts means 40. In this manner, the lubricant may flow along the means 40 and it may be distributed by the latter on the chain C.

[0087] For example, the lubricant may flow along the bristles of the brush 41 or along the spatula 42.

[0088] Depending on a particular aspect of the invention, the portion 30 may be configured to guide the action of the user during use.

[0089] Suitably, the operative portion 30 may therefore comprise guide elements 31 to guide the mutual sliding of the chain C and of the accessory 10.

[0090] For example, the operative portion 30 may comprise a pair of opposite longitudinal walls 32, 33. This may allow to form a seat 39 between walls 32, 33 for the chain C.

[0091] In greater detail, the chain C may define an axis. The walls 32 and 33 may remain in use on opposite sides with respect to such axis so that the C chain can slide between the walls 32, 33.

[0092] Suitably, there may be provided for a connection wall 34 substantially perpendicular to walls 32 and 33 to delimit the seat 39. The seat 39 may therefore be substantially C- shaped.

[0093] Preferably, the means 40 may fully or partially occupy the seat 39. Advantageously, the means 40 may be configured so that during use the means 40 allow the sliding of the chain C in the seat 39 and at the same time so that the means 40 impact with the chain C.

[0094] Preferably the means 40 may be flexible and / or rotary. Should they be rotary, preferably, the means 40 may rotate with respect to the wall 34.

[0095] Preferably, the means 40 may extend from the wall 34 whether they rotate or should they be flexible.

[0096] Suitably, the outlet 12 may be at the wall 34. In this manner, the outflowing lubricant may flow along the means 40 up to the chain C.

[0097] Possibly, the outlet 12 may be at the wall 34 upstream with respect to the direction of mutual sliding of the chain C and the accessory 10 so that the lubricant runs over the chain C and is subsequently distributed by the means 40.

[0098] It is clear that in the latter case, during use, the lubricant may interact with both the chain and the means 40.

[0099] According to a particular aspect of the invention, there may be provided for a nozzle 14 that is f luidica lly connected with outlet 12 or that defines the outlet 12.

[0100] Such nozzle 14 may have an extension that is wider than the height-wise extension. The nozzle 14 may have a width that is larger than half the width of the seat 39. Preferably, the nozzle 14 may be divergent.

[0101] In the present document, the width and length are understood to lie in a plane n. The plane n may be the plane in which the two side walls 32, 33 lie. For example, the images of FIG. 8, FIG. 10, FIG. 12, FIG. 14, FIG. 16 and FIG. 18 are sections taken along the plane n.

[0102] According to a particular aspect, the section 30 may be configured depending on the intended use. For example, the width LA and the length LU of the seat 39 may be configured depending on the size of the chain C.

[0103] The distance between the walls 32 and 33 may define the width LA. The length of walls 32 and 33 may define the length LU.

[0104] The chain C may have a width of A and it may have a height B.

[0105] In greater detail, the chain C may be of the link type, the so-called articulated chain or Galle, and it may therefore comprise a plurality of links each of which has a pair of opposite plates. The distance between the outer surfaces of the opposite plates may define width A. The height B may be perpendicular to the width A. Both the width A and the height B may be perpendicular to the longitudinal extension axis of the chain C.

[0106] The portion 30 may therefore be configured so that when the chain C is in the seat 39, that is during use, the walls 32 and 33 external with respect to the chain C. In other words, the width LA may be slightly greater than the width A .

[0107] Preferably the width LA may be substantially equal to the width A and only slightly larger so that walls 32, 33 guide sliding of the device 1 during use.

[0108] Suitably, the length LU may be substantially equal to the height B of the chain C.

[0109] In this manner, during use, the chain C may remain substantially entirely inside the seat 39.

[0110] Suitably, the width L4 of the means 40 may be less than the width LA. This will allow to form an interspace 45 between the walls 32, 33 and the means 40. Preferably, the width of the means 40 may be substantially equal to or slightly smaller than the distance between the links of chain G, that is substantially equal to or slightly less than the length of the roller of the chain between the links.

[0111] Advantageously, during use, in this manner the plates of the chain C may remain at the interspaces 45 while the roller of the chain C may remain at the means 40.

[0112] Thanks to this characteristic, the dispersion of the lubricant on the chain may be particularly effective.

[0113] Preferably, the nozzle 14 may have a width LI which may be slightly smaller than the width L4 of the means 40.

[0114] In this manner, the lubricant may flow out from the outlet 12 distributed along such width LI. Advantageously, the distribution of the lubricant may be even more effective.

[0115] According to an embodiment shown in FIG. 11 and FIG. 13, the accessory 10 may be particularly adapted for the chain C of a bicycle. In this case the width LA may measure 7 mm and the length LU may measure 16 mm. The means 40 may preferably be the spatula 42.

[0116] According to a different embodiment shown in FIG. 15, the accessory 10 may be particularly adapted for the chain C of a motorcycle. In this case the width LA may measure 20 mm and the length LU may measure 26 mm. The means 40 may preferably be the spatula 42.

[0117] According to a different embodiment shown in FIG. 17, the accessory 10 may be particularly adapted for the chain C of a motorcycle. In this case the width LA may measure 30 mm and the length LU may measure 26 mm. The means 40 may preferably be the spatula 42.

[0118] Operatively, the user may provide the device 1 with the lubricant, position it so that chain C is inside seat 39, mutually move chain C and accessory 10, and actuate the means 110 to promote the dispensing of the lubricant.

[0119] Possibly, the user may provide the dispenser or injector 100, 100' and an accessory 10, mutually couple the accessory 10 and the dispenser or the injector 100, 100' to form the device 1.

[0120] Should the nozzle or injector 100, 100' be of the multipurpose type, once through with operation of lubricating the chain C, the operator may remove the accessory 10 , that is de-couple the latter from the dispenser or injector 100, 100' and safely put away the latter or use the same dispenser or injector 100, 100' with a different accessory 10, for example to lubricate a different chain C.

[0121] It is clear that regardless of the number and type of accessories 10, there may be provided for a kit which comprises one or more of the following:

[0122] - a dispenser or injector 100, 100';

[0123] - an extension;

[0124] - one or more dispenser accessories 10 described above, preferably provided with walls 32, 33 to guide the action of the user;

[0125] - an accessory of a convergent tubular shape of the known type, so-called teardrop;

[0126] - an accessory in the form of a brush without guide walls;

[0127] - a UV lamp.

[0128] The accessories 10, the tubular accessory and the accessory in the form of a brush, all of which can be alternatively selectively coupled with the dispenser or injector 100, 100', possibly by means of the extension.

[0129] The extension may be of the angular type, that is, it may have two tubular sections whose axes are incident, for example forming an angle of about 90°.

[0130] The UV lamp allows to check whether the liquid is applied correctly.

[0131] Suitably, the kit may comprise a plurality of accessories 10. Such aspect may be advantageous for the use described above with a multipurpose dispenser or injector 100, 100'.

[0132] Advantageously, the kit may comprise a plurality of accessories 10 different from each other. The accessories 10 of the plurality may all be alternatively selectively coupled with the same dispenser or injector 100, 100'.

[0133] The accessories 10 of the kit may have a different type of means 40.

[0134] For example, some may be brushes 41 and some may be spatulas 42. In this manner, the user may choose the preferred tool, for example depending on the amount of dirt on the chain.

[0135] The accessories 10 of the kit may be different in terms of size of the portion 30.

[0136] For example, the width LA of the seat 39 may be different so that the same kit can be used with chains C of different widths (for example, three accessories 10 having the width LA of the seat: 7 mm, 20 mm, 30 mm). Similarly, the accessories 10 of the kit may have a different length LU of the seat 39.

[0137] The accessories 10 of the kit may be different in terms of size of the portion 20.

[0138] For example, at least one accessory 10 may have the coupling portion 21 configured to form a Luer-lock coupling, and at least one accessory 10 may have the smooth tubular coupling portion 21 so as to be coupled, for example by interference, with the portion 121.

[0139] For example, the kit may be intended for a type of chain, for example for bicycles or motorcycles, and may therefore comprise at least the following accessories 10 all having same width LA:

[0140] - an accessory 10 with spatula 42 and smooth tubular portion 21;

[0141] - an accessory 10 with brush 41 and portion 21 with external thread 21'.

[0142] Suitably, the user may therefore prepare the kit and select the accessory of interest.

[0143] The selected accessory may therefore be coupled directly with the dispenser or injector. Possibly, there may be provided for the extension which may be coupled with the dispenser and subsequently the accessory may be coupled with the extension. Possibly, the selected accessory may be coupled firstly with the extension and subsequently the extension with the dispenser without departing from the scope of protection of the present invention.

[0144] This is advantageous for the user, who can choose whether and when to use the preferred distribution means 40, for example the spatula first and then the brush. Furthermore, the kit of accessories

[0145] The invention is susceptible to numerous modifications and variants all falling within the inventive concept outlined in the attached claims. All details can be replaced by other technically equivalent elements, and the materials can be different depending on the needs, without departing from the scope of protection of the invention. Even though the invention has been described with particular reference to the attached figures, the reference numbers utilised in the description and in the claims are meant for improving the intelligibility of the invention and thus do not limit the claimed scope of protection in any manner whatsoever.
