Description

[0001] SUPPORT BASE FOR A CASE OF A CYCLE OR A MOTORCYCLE

[0002] AND SYSTEM COMPRIS ING SAID SUPPORT BASE AND SAID CASE

[0003] The present invention relates to a support base for a case of a cycle or a motorcycle .

[0004] As is known, cycles or motorcycles are generally provided with a support base for attaching a case to the frame of the cycle or motorcycle . In particular, the support base is fixed to the frame of the cycle or motorcycle , and the case is supported by the support base and attached thereto by attaching means .

[0005] During the motion o f the cycle or motorcycle , the support base transmits vibrations to the case ; therefore , support bases of the prior art comprise a damping system for vibration .

[0006] Known damping systems comprise elastically deformable elements , such as for example rubber pads , mounted between the support base and the wall o f the case adapted to be mounted with the support base , so that when the case is attached to the support base , said elastically deformable elements are elastically deformed, damping the transmis sion of vibrations to the case and allowing the case to be maintained firmly attached to the support base .

[0007] Disadvantageously, known elastically deformable elements are subj ect to wear, limiting the excursion o f the elastically deformable element and thus limiting its elastic deformation capacity over time . As the wear of the elastically deformable element increases , there is a corresponding lower elastic thrust against the case , and therefore a lower damping capacity for vibrations . An obj ect of the present invention is to make a support base for a case o f a cycle or a motorcycle that is more durable and maintains damping capacity for vibrations over time .

[0008] In accordance with the invention, such purpose is achieved with a support base according to claim 1 .

[0009] Another obj ect of the present invention is to make an attaching system for a case of a cycle or a motorcycle that is more durable and maintains damping capacity for vibrations over time .

[0010] In accordance with the invention, such other purpose is achieved by an attaching system according to claim 11 .

[0011] These and other obj ects according to the present invention are achieved by making a support base for a case of a cycle or a motorcycle , as set forth in claim 1 .

[0012] Further features of the support base are the subj ect of the dependent claims .

[0013] The features and advantages of a support base for a case of a cycle or a motorcycle according to the present invention will be more apparent from the following exemplary and non-limiting description, with reference to the attached schematic drawings , in which :

[0020] Figure 7 is an enlarged view of Figure 5 , showing a third damping element according to an alternative ;

[0021] - Figure 8 is a sectional view along line VI I I- VI I I of Figure 2 , showing fourth damping elements ;

[0022] Figure 9 is an exploded side view of an attaching system comprising the case of a cycle or a motorcycle and the support base according to the particular embodiment of the present invention .

[0023] With reference to the cited figures , a support base for a case of a cycle or a motorcycle , overall indicated by 10 , is shown .

[0024] As particularly shown in Figure 8 , the support base 10 on one side is attachable with a case 200 of a cycle or a motorcycle 300 and, on the other side , i s fixable to a frame 310 of the cycle or motorcycle 300 .

[0025] The case 200 comprises at least one wall 210 configured to be attached to the support base 10 .

[0026] As particularly shown in Figures 1-4 , the support base 10 comprises a supporting shel f 11 for the case 200 , speci fically for the wall 210 .

[0027] In Figure 4 , a longitudinal geometric axis X is shown, which is perpendicular to the supporting shel f 11 of the support base 10 .

[0028] The support base 10 is attachable with the case 200 by switching from a detaching configuration to an attaching configuration .

[0029] The detaching configuration of the support base 10 provides that the support base 10 is detached from the case 200 .

[0030] The attaching configuration of the support base 10 provides that the support base 10 is attached with said at least one wall 210 .

[0031] The support base 10 comprises attaching means 12 for firmly attaching the case 200 in the attaching configuration .

[0032] As particularly shown in Figures 1-3 , the attaching means 12 are preferably three and comprise a stud and two mushroom-shaped attachments .

[0033] In more detail , the attaching configuration provides that the wall 210 is arranged at the supporting shel f 11 and that the case is attached to the support base 10 through the attaching means 12 .

[0034] The detaching configuration provides that the case 210 , speci fically the wall 210 , is detached from the supporting shel f 11 .

[0035] The support base 10 comprises at least one damping system 100 .

[0036] More preferably, the support base 10 comprises four damping systems 100 , as particularly shown in Figure 2 , so as to hold the case 200 more securely while damping vibrations from any direction .

[0037] The damping system 100 i s adapted to damp vibrations between the support base 10 and the case 200 when the support base 10 is in the attaching configuration .

[0038] The damping system 100 comprises a housing seat 110 dug inside the support base 10 .

[0039] The housing seat 110 is open towards the outside . The term "outside" means a space that is not comprised within the housing seat 110 , i . e . , a space that is external to the body of the support base 10 .

[0040] The housing seat 110 is de fined by a bottom wall

[0041] 111 and a lateral wall 112 . The bottom wall 111 delimits the depth of the housing seat along a loading direction, which is parallel to the longitudinal geometric axis X, while the lateral wall 112 delimits the width of the housing seat 110 in a direction transverse to the loading direction .

[0042] In practice , the housing seat 110 makes a gap 113 delimited by the bottom wall 111 and the lateral wall

[0043] 112 .

[0044] The damping system 100 comprises an elastic element 120 housed at least partially inside the housing seat 110 .

[0045] Preferably, the elastic element 120 counteracts with the bottom wall 111 .

[0046] Preferably, the elastic element 120 comprises a first end 121 and a second end 122 opposite to the first end 121 . The first end 121 and the second end 122 are opposite relative to the loading direction . The first end 121 is inside the housing seat 110 and counteracts with the bottom wall 111 .

[0047] As will be better explained below, the elastic element 120 is adapted to switch from a lower compression configuration to a higher compression configuration .

[0048] The damping system 100 comprises a first damping element 130 mounted with the elastic element 120 . Preferably, the damping element 130 is mounted with the second end 122 of the elastic element 120 .

[0049] The first damping element 130 is sl idingly mounted with the housing seat 110 along the loading direction . The sliding of the first damping element 130 causes the elastic element 120 to switch from the lower compression configuration to the higher compression configuration . In other words , the sliding o f the first damping element 130 towards the bottom wall 111 corresponds to the compression of the elastic element 120 .

[0050] The first damping element 130 comprises a first portion 131 that protrudes from the housing seat 110 , at least in said detaching configuration .

[0051] The term "protrude" means that the first portion 131 extends from the housing seat 110 beyond the supporting shel f 11 towards the outside of the housing seat 110 .

[0052] The first portion 131 of the first damping element 130 is adapted to engage against the wall 210 of the case 200 in the attaching configuration .

[0053] The first damping element 130 is adapted to elastically deform along the loading direction, switching from a lower deforming configuration to a higher deforming configuration .

[0054] The switching from the lower deforming configuration to the higher deforming configuration of the first damping element 130 occurs when the support base 10 switches from the detaching configuration to the attaching configuration .

[0055] The detaching configuration corresponds to the lower compression configuration of the elastic element 120 and the lower deforming configuration of the first damping element 130 . When the case 200 is detached from the support base 10 , and in particular is not arranged at the supporting shel f 11 , the first portion 131 i s disengaged from the wall 210 o f the case 200 , the elastic element 120 is in the lower compression configuration, and the first damping element 130 is in the lower deforming configuration .

[0056] The attaching configuration provides that the first damping element 130 is engaged against the wall 210 of the case 200 , the elastic element 120 is in the higher compression configuration, and the first damping element 130 is in the higher deforming configuration . When the case 200 is attached to the support base 10 , particularly when it is arranged at the supporting shel f 11 , the first portion 131 is engaged against the wall 210 of the case 200 and switches from the lower deforming configuration to the higher deforming configuration . The first portion 131 presses against the wall 210 with a force proportional to an elastic deformation of the first damping element 130 . In this way, the first damping element 130 is capable of damping vibrations between the support base 10 and the case 200 .

[0057] In addition to the aforementioned elastic deformation, the first damping element 130 slides inside the housing seat 110 and compresses the elastic element 120 switching from the lower compression configuration to the higher compression configuration, thereby loading the elastic element 120 in compression with an elastic force .

[0058] The sliding of the first damping element 130 is due to the fact that the wall 210 of the case 200 is arranged at the supporting shel f 11 and, at the same time , is engaged against the first portion 131 of the first damping element 130 , which protrudes beyond the supporting shel f 11 , as previously explained .

[0059] The loaded elastic force pushes in turn the first damping element 130 , and in particular the first portion 131 , against the wall 210 of the case 200 .

[0060] Advantageously, the first portion 131 presses against the wall 210 o f the case 200 in the attaching configuration due to both the elastic deformation and the loaded elastic force .

[0061] Advantageously, the thrust contribution given by the elastic element 120 allows the first damping element 130 to damp vibrations between the support base 10 and the case 200 even when the elastic deformation decreases .

[0062] Indeed, i f the elastic deformation decreases , then the contribution of the elastic deformation to the thrust of the first portion 131 against the wall is lower . The lower thrust of the first portion 131 , caused by the lower elastic deformation, results in greater sliding of the first damping element 130 inside the housing seat 110 ( towards the bottom wall 111 ) , thereby further compressing the elastic element 120 .

[0063] In such case , the first damping element 130 loads the elastic element 120 in compression with a greater elastic force compared to a situation in which the elastic deformation of the f irst damping element 130 has not decreased .

[0064] In this way, the compression contribution of the elastic element 120 to the thrust of the first portion 131 of the first damping element 130 against the wall 210 is greater and allows to recover the lost contribution of the elastic deformation of the first damping element 130 that has decreased .

[0065] Preferably, each damping system 100 comprises a second damping element 140 housed inside a second housing seat 110 .

[0066] According to a preferable embodiment shown in Figure 4 , the second damping element 140 is housed inside the housing seat 110 between the first damping element 130 and the bottom wall 111 .

[0067] Preferably, the second damping element 140 is adapted to counteract with the first damping element 130 .

[0068] In such case , the second damping element 140 is adapted to elastically deform along the loading direction, switching from a lower deforming configuration to a higher deforming configuration .

[0069] The lower deforming configuration of the second damping element 140 corresponds to the detaching configuration .

[0070] The higher deforming configuration of the second damping element 140 provides that the first damping element 130 counteracts with the second damping element 140 .

[0071] Preferably, the higher deforming configuration of the second damping element 140 corresponds to the attaching configuration of the support base 10 .

[0072] When the support base 10 is in the attaching configuration, the first damping element 130 can slide inside the housing seat 110 until counteracting with the second damping element 140 , causing the latter to switch from the lower deforming configuration to the higher deforming configuration .

[0073] In such case , the second damping element 140 presses in turn against the first damping element 130 with a force proportional to the elastic deformation of the second damping element 140 . Therefore , the first damping element 130 , and in particular the first portion 131 , presses against the wall 210 also due to the elastic deformation of the second damping element 140 .

[0074] Meanwhile , the elastic element 120 still switches from the lower compression configuration to the higher compression configuration, as previously explained .

[0075] As a result , the thrust contribution of the first portion 131 against the wall 210 is given by the elastic deformation of the first damping element 130 , the elastic deformation of the second damping element 140 , and the loaded elastic force of the elastic element 120 .

[0076] In other words , the second damping element 140 also contributes to the thrust of the first portion 131 against the case 200 .

[0077] For example , when the case 200 is very heavy, there is a greater sliding of the first damping element 130 towards the bottom wall 111 of the housing seat 110 until counteracting with the second damping element 140 .

[0078] This allows , for example , a more ef fective damping of vibrations between the support base 10 and the case 200 . Indeed, in such case , the thrust contribution is always given by both damping elements 130 , 140 .

[0079] Preferably, the first damping element 130 counteracts with the second damping element 140 , for example , as a result of strong impacts when the cycle or motorcycle 300 encounters a pothole on the road . In other words , the second damping element 140 can be an endstroke .

[0080] In such case , the first damping element 130 slides further inside the housing seat 110 ( towards the bottom wall 111 ) until counteracting with the second damping element 140 . In this way, the second damping element 140 elastically deforms due to the contact and sliding of the first damping element 130 when the motorcycle encounters a pothole on the road .

[0081] Preferably, the damping system 100 comprises a bushing 150 mounted with the first damping element 130 .

[0082] In such case , the bushing 150 is mounted with the elastic element 120 .

[0083] Preferably, as shown in Figure 4 , the first damping element 130 passes through the bushing 150 such that the first portion 131 still protrudes from the bushing 150 .

[0084] Furthermore , the elastic element 120 contacts the bushing 150 but does not contact the first portion 131 . In particular, as shown in Figure 4 , the second end 122 of the elastic element 120 abuts with the bushing 150 .

[0085] Preferably, the bushing 150 is rigid .

[0086] Advantageously, the rigid bushing 150 allows the separation of the elastic deformation of the first portion 131 from the compression of the elastic element 120 .

[0087] In other words , the rigid bushing 150 allows the first portion 131 not to deform due to the thrust on it by the elastic element 120 when it is in the higher compression configuration .

[0088] Preferably, the housing seat 110 comprises an endstroke element 114 . In such case , the damping system 100 comprises an abutting element 160 integral with the first damping element 130 and arranged between the endstroke element 114 and the bottom wall 111 of the housing seat 110 .

[0089] The abutting element 160 is adapted to abut against the endstroke element 114 .

[0090] Preferably, as shown in Figure 4 , the endstroke element 114 extends from an edge of said housing seat 110 in a direction transverse to the loading direction .

[0091] Preferably, the abutting element 160 abuts against the endstroke element 114 in the detaching configuration . In such case , the elastic element 120 can be preloaded in compression .

[0092] Preferably, the abutting element 160 does not abut with the endstroke element 114 when the support base 10 is in the detaching configuration . In such case , the abutting element 160 remains arranged between the endstroke element 114 and the bottom wall 111 .

[0093] Preferably, the abutting element 160 can slide integrally with the first damping element 130 ins ide the housing seat 110 until abutting against the endstroke element 114 in the attaching configuration .

[0094] Advantageously, the endstroke element 114 allows to prevent the elastic element 120 , the first damping element 130 , and the abutting element 160 from completely coming out of the housing seat 110 in both the detaching configuration and the attaching configuration .

[0095] Preferably, the bushing 150 comprises the abutting element 160 . In such case , the abutting element 160 , on one side , abuts with the elastic element 120 and, on the other side , faces the endstroke protrusion 114 . In the particular illustrated embodiment , the elastic element 120 is preferably a helical spring . In such case , the first damping element 130 can at least partially pass through the helical spring, so that the first portion 131 comes out of such spring .

[0096] In the case where the damping system 100 comprises the second damping element 140 , such second damping element 140 can be enclosed by said helical spring . In such case , as shown in the figures , both the helical spring and the second damping element 140 contact the bottom wall 111 .

[0097] Preferably, the support base 10 comprises more than one damping system 100 . In such a case , the damping systems 100 are appropriately spaced apart from each other so that the support base 10 is capable o f absorbing vibrations from every direction .

[0098] Preferably, the support base 10 comprises four damping systems 100 . In the particular embodiment shown in the figures , the damping systems 100 are arranged at a distance therebetween on the shelf 11 of the support base 100 .

[0099] The present invention also relates to an attaching system 400 comprising the support base 10 and the case 200 .

[0100] In the attaching configuration, the wall 210 of the case 200 is attached to the support base 10 . In particular, the wall 210 is arranged at the supporting shel f 11 . Furthermore , the first portion 131 of the first damping element 130 is in contact with the wall 210 in the attaching configuration .

[0101] Furthermore , the attaching means 12 firmly attach the case 200 to the support base 10 .

[0102] Advantageously, the support base 10 according to the present invention is more durable and maintains damping capacity for vibrations over time .

[0103] Advantageously, the attaching system 400 for the case 200 of a cycle or a motorcycle 300 is more durable and maintains damping capacity for vibrations over time .

[0104] Alternatively, it can be provided that the support base 10 comprises only one damping system 100 .

The third damping element 145 is fixedly positioned above a wall of said support base 10 . The wall 11 of the support base 10 i s the one facing the wall 210 of the case 200 . The third damping element 145 has a height lower than a height of a portion 131 o f the first damping element 130 extending outside the housing seat 110 . The height is measured along a direction parallel to the loading direction .
