Abstract
Description
Technical Field
[0001] This invention relates to a support base for a housing used in bicycles or motorcycles. Background Technology
[0002] As is known, bicycles or motorcycles typically have a support base for attaching the housing to the frame of the bicycle or motorcycle. In particular, the support base is fixed to the frame of the bicycle or motorcycle, and the housing is supported by the support base and attached to the support base via an attachment device.
[0003] During bicycle or motorcycle movement, the support base transmits vibrations to the housing; therefore, prior art support bases include damping systems for vibration.
[0004] Known damping systems include resiliently deformable elements, such as rubber pads, which are mounted between a support base and the wall of a housing adapted to be mounted together with the support base, such that when the housing is attached to the support base, the resiliently deformable element elastically deforms to dampen the transmission of vibrations to the housing and allow the housing to remain firmly attached to the support base.
[0005] Disadvantageously, over time, the known elastically deformable element undergoes wear, which limits its displacement and thus its elastic deformation capacity. As wear of the elastically deformable element increases, the elastic thrust on the housing decreases accordingly, and therefore the damping capacity against vibration is reduced. Summary of the Invention
[0006] The purpose of this invention is to manufacture a support base for a bicycle or motorcycle housing that is more durable and retains its damping capacity against vibrations over time.
[0007] According to the present invention, such an objective is achieved by the support base according to claim 1.
[0008] Another object of the present invention is to manufacture an attachment system for a housing of a bicycle or motorcycle that is more durable and retains its damping ability against vibrations over time.
[0009] According to the invention, this other objective is achieved by the attachment system according to claim 11.
[0010] These and other objectives according to the invention are achieved by manufacturing a support base for a bicycle or motorcycle housing according to claim 1.
[0011] Other features of the support base are the subject of the dependent claims. Attached Figure Description

[0022] Referring to the accompanying drawings, a support base for a housing for a bicycle or motorcycle is shown, generally indicated by 10.
[0023] like Figure 8 As specifically shown, the support base 10 can be attached to the housing 200 of the bicycle or motorcycle 300 on one side and can be fixed to the frame 310 of the bicycle or motorcycle 300 on the other side.
[0024] The housing 200 includes at least one wall 210, which is configured to be attached to the support base 10.
[0025] like Figures 1 to 4 As specifically shown, the support base 10 includes a support shelf 11 for the housing 200, and particularly for the wall 210.
[0026] exist Figure 4 The image shows a longitudinal geometric axis X, which is perpendicular to the support shelf 11 of the support base 10.
[0027] The support base 10 can be attached to the housing 200 by switching from a disassembly configuration to an attachment configuration.
[0028] The support base 10 is configured to be detached from the housing 200.
[0029] The attachment configuration of the support base 10 is configured such that the support base 10 is attached to the at least one wall 210.
[0030] The support base 10 includes an attachment device 12 for securely attaching the housing 200 in an attachment configuration.
[0031] like Figures 1 to 3 As specifically shown, the attachment device 12 is preferably three in number and includes studs and two mushroom-shaped attachments.
[0032] More specifically, the attachment configuration is such that wall 210 is arranged at support shelf 11, and the housing is attached to support base 10 via attachment device 12.
[0033] The disassembled configuration is set as a box 210, and the specific ground wall 210 is disassembled from the support shelf 11.
[0034] The support base 10 includes at least one damping system 100.
[0035] More preferably, such as Figure 2 As specifically shown, the support base 10 includes four damping systems 100 to more firmly hold the housing 200 while damping vibrations from any direction.
[0036] When the support base 10 is in the attachment configuration, the damping system 100 is adapted to dampen the vibration between the support base 10 and the housing 200.
[0037] The damping system 100 includes a receiving seat 110 excavated inside the support base 10.
[0038] The receiving seat 110 is open to the outside. The term "outside" refers to the space not included in the receiving seat 110, that is, the space outside the body supporting the base 10.
[0039] The receiving seat 110 is defined by a bottom wall 111 and a side wall 112. The bottom wall 111 defines the depth of the receiving seat along the loading direction parallel to the longitudinal geometric axis X, while the side wall 112 defines the width of the receiving seat 110 in the direction transverse to the loading direction.
[0040] In practice, the receiving seat 110 is formed with a gap 113 defined by the bottom wall 111 and the side wall 112.
[0041] The damping system 100 includes an elastic element 120 that is at least partially housed within a housing portion 110.
[0042] Preferably, the elastic element 120 abuts against the bottom wall 111.
[0043] Preferably, the elastic element 120 includes 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 to the loading direction. The first end 121 is located inside the receiving seat 110 and abuts against the bottom wall 111.
[0044] As will be explained better below, the elastic element 120 is adapted to switch from a lower compression configuration to a higher compression configuration.
[0045] The damping system 100 includes a first damping element 130 mounted together with the elastic element 120. Preferably, the damping element 130 is mounted together with a second end 122 of the elastic element 120.
[0046] The first damping element 130 is slidably mounted to the receiving seat 110 along the loading direction. The sliding of the first damping element 130 causes the elastic element 120 to switch from a lower compression configuration to a higher compression configuration. In other words, the sliding of the first damping element 130 toward the bottom wall 111 corresponds to the compression of the elastic element 120.
[0047] The first damping element 130 includes a first portion 131 that protrudes from the receiving seat 110 at least in the disassembly configuration.
[0048] The term "protrusion" refers to the first part 131 extending beyond the support shelf 11 from the receiving seat 110 toward the outside of the receiving seat 110.
[0049] The first portion 131 of the first damping element 130 is adapted to engage with the wall 210 of the housing 200 in an attachment configuration.
[0050] The first damping element 130 is adapted to elastically deform along the loading direction to switch from a lower deformation configuration to a higher deformation configuration.
[0051] When the support base 10 switches from the disassembly configuration to the attachment configuration, the first damping element 130 switches from the lower deformation configuration to the higher deformation configuration.
[0052] The disassembly configuration corresponds to the lower compression configuration of the elastic element 120 and the lower deformation configuration of the first damping element 130. When the housing 200 is disassembled from the support base 10 and, in particular, not arranged at the support shelf 11, the first portion 131 is disengaged from the wall 210 of the housing 200, the elastic element 120 is in the lower compression configuration, and the first damping element 130 is in the lower deformation configuration.
[0053] The attachment configuration is such that the first damping element 130 engages with the wall 210 of the housing 200, the elastic element 120 is in a higher compression configuration, and the first damping element 130 is in a higher deformation configuration. When the housing 200 is attached to the support base 10, particularly when the housing 200 is arranged at the support shelf 11, the first portion 131 engages with the wall 210 of the housing 200 and switches from a lower deformation configuration to a higher deformation configuration. The first portion 131 presses against the wall 210 with a force proportional to the elastic deformation of the first damping element 130. In this way, the first damping element 130 is able to dampen vibrations between the support base 10 and the housing 200.
[0054] In addition to the elastic deformation mentioned above, the first damping element 130 slides inside the receiving seat 110 and compresses the elastic element 120 so that the elastic element 120 switches from a lower compression configuration to a higher compression configuration, thereby loading the elastic element 120 in a compressive manner with elastic force.
[0055] The sliding of the first damping element 130 is caused by the fact that the wall 210 of the housing 200 is arranged at the support shelf 11 and simultaneously abuts against the first portion 131 of the first damping element 130 that protrudes beyond the support shelf 11, as explained above.
[0056] The applied elastic force then pushes the first damping element 130, and in particular the first portion 131, against the wall 210 of the housing 200.
[0057] Advantageously, in the attachment configuration, the first part 131 presses against the wall 210 of the housing 200 due to both elastic deformation and the applied elastic force.
[0058] Advantageously, the thrust contribution provided by the elastic element 120 allows the first damping element 130 to dampen the vibration between the support base 10 and the housing 200 even when the elastic deformation decreases.
[0059] In fact, if the elastic deformation decreases, the contribution of the elastic deformation to the thrust of the first portion 131 against the wall is smaller. The smaller thrust of the first portion 131 caused by the lower elastic deformation leads to greater sliding of the first damping element 130 inside the receiving seat 110 (towards the bottom wall 111), thereby further compressing the elastic element 120.
[0060] In this case, compared to the case where the elastic deformation of the first damping element 130 is not reduced, the first damping element 130 loads the elastic element 120 with a greater elastic force in a compressive manner.
[0061] In this way, the elastic element 120 makes a greater contribution to the compression of the thrust of the first portion 131 of the first damping element 130 against the wall 210, and allows for compensation of the loss contribution of the reduced elastic deformation of the first damping element 130.
[0062] Preferably, each damping system 100 includes a second damping element 140 housed within the second receiving seat 110.
[0063] according to Figure 4 In the preferred embodiment shown, the second damping element 140 is housed inside the receiving seat 110 between the first damping element 130 and the bottom wall 111.
[0064] Preferably, the second damping element 140 is adapted to counteract the first damping element 130.
[0065] In this case, the second damping element 140 is adapted to elastically deform along the loading direction to switch from a lower deformation configuration to a higher deformation configuration.
[0066] The lower deformation configuration of the second damping element 140 corresponds to the disassembly configuration.
[0067] The higher deformation configuration of the second damping element 140 is configured such that the first damping element 130 and the second damping element 140 counteract each other.
[0068] Preferably, the higher deformation configuration of the second damping element 140 corresponds to the attachment configuration of the support base 10.
[0069] When the support base 10 is in the attachment configuration, the first damping element 130 can slide inside the receiving seat 110 until it abuts against the second damping element 140, thereby causing the second damping element 140 to switch from a lower deformation configuration to a higher deformation configuration.
[0070] In this situation, the second damping element 140 then presses 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, also presses against the wall 210 due to the elastic deformation of the second damping element 140.
[0071] At the same time, as explained above, the elastic element 120 still switches from a lower compression configuration to a higher compression configuration.
[0072] Therefore, the thrust contribution of the first part 131 against the wall 210 is provided by the elastic deformation of the first damping element 130, the elastic deformation of the second damping element 140, and the elastic force applied by the elastic element 120.
[0073] In other words, the second damping element 140 also contributes to the thrust of the first part 131 against the housing 200.
[0074] For example, when the housing 200 is very heavy, there is a greater sliding of the first damping element 130 toward the bottom wall 111 of the receiving seat portion 110 until it comes into contact with the second damping element 140.
[0075] This allows for, for example, more effective damping of vibrations between the support base 10 and the housing 200. In fact, in this case, the thrust contribution is always provided by the two damping elements 130 and 140.
[0076] Preferably, the first damping element 130 abuts against the second damping element 140, for example, due to the strong impact when the bicycle or motorcycle 300 encounters a pothole on the road. In other words, the second damping element 140 may be at the end of its stroke.
[0077] In this case, the first damping element 130 slides further inside the receiving seat 110 (towards the bottom wall 111) until it comes into contact with the second damping element 140. In this way, when the motorcycle encounters potholes on the road, the second damping element 140 elastically deforms due to the contact and sliding of the first damping element 130.
[0078] Preferably, the damping system 100 includes a bushing 150 mounted together with the first damping element 130.
[0079] In this case, the bushing 150 is mounted together with the elastic element 120.
[0080] Preferably, such as Figure 4 As shown, the first damping element 130 passes through the bushing 150, such that the first portion 131 still protrudes from the bushing 150.
[0081] Furthermore, the elastic element 120 contacts the bushing 150 but not the first portion 131. Specifically, as... Figure 4 As shown, the second end 122 of the elastic element 120 abuts against the bushing 150.
[0082] Preferably, the bushing 150 is rigid.
[0083] Advantageously, the rigid bushing 150 allows the elastic deformation of the first portion 131 to be separated from the compression of the elastic element 120.
[0084] In other words, the rigid bushing 150 allows the first portion 131 to not deform due to the thrust exerted on the first portion 131 by the elastic element 120 when the elastic element 120 is in a higher compression configuration.
[0085] Preferably, the receiving seat 110 includes a travel end element 114.
[0086] In this case, the damping system 100 includes an abutment element 160, which is integral with the first damping element 130 and is disposed between the travel end element 114 of the receiving seat portion 110 and the bottom wall 111.
[0087] The abutment element 160 is adapted to abut against the travel end element 114.
[0088] Preferably, such as Figure 4 As shown, the stroke end element 114 extends from the edge of the receiving seat 110 in a direction transverse to the loading direction.
[0089] Preferably, in the disassembly configuration, the abutment element 160 abuts against the stroke end element 114. In this case, the elastic element 120 can be preloaded in a compressed manner.
[0090] Preferably, when the support base 10 is in the disassembled configuration, the abutment element 160 does not abut against the stroke stop element 114. In this case, the abutment element 160 remains disposed between the stroke end element 114 and the bottom wall 111.
[0091] Preferably, in the attachment configuration, the abutment element 160 can slide integrally with the first damping element 130 inside the receiving seat 110 until it abuts against the stroke end element 114.
[0092] Advantageously, the travel end element 114 allows the resilient element 120, the first damping element 130, and the abutment element 160 to be completely dislodged from the receiving seat 110 in both the disassembly and attachment configurations.
[0093] Preferably, the bushing 150 includes an abutment element 160. In this case, the abutment element 160 abuts against the resilient element 120 on one side and protrudes toward the travel end 114 on the other side.
[0094] In the particular embodiment illustrated, the elastic element 120 is preferably a helical spring. In this case, the first damping element 130 may at least partially pass through the helical spring, such that a first portion 131 is exposed from the spring.
[0095] When the damping system 100 includes a second damping element 140, this second damping element 140 can be enclosed by the helical spring. In this case, as shown, both the helical spring and the second damping element 140 are in contact with the bottom wall 111.
[0096] Preferably, the support base 10 includes more than one damping system 100. In this case, the damping systems 100 are appropriately spaced apart from each other so that the support base 10 can absorb vibrations from each direction.
[0097] Preferably, the support base 10 includes four damping systems 100. In a particular embodiment shown in the figures, the damping systems 100 are arranged on the shelf 11 of the support base 100 at a distance from each other.
[0098] The present invention also relates to an attachment system 400 comprising a support base 10 and a housing 200.
[0099] In the attachment configuration, the wall 210 of the housing 200 is attached to the support base 10. In particular, the wall 210 is arranged at the support shelf 11.
[0100] Furthermore, in the attachment configuration, the first portion 131 of the first damping element 130 contacts the wall 210.
[0101] In addition, the attachment device 12 securely attaches the housing 200 to the support base 10.
[0102] Advantageously, the support base 10 according to the invention is more durable and retains its damping ability against vibration over time.
[0103] Advantageously, the attachment system 400 of the housing 200 for bicycles or motorcycles 300 is more durable and retains its damping ability against vibrations over time.
[0104] Alternatively, the support base 10 may be configured to include only one damping system 100.
[0105] Alternatively, the support base 10 may include three damping systems 100 arranged on the shelf 11 at 120 degrees to each other.
[0106] Alternatively, the abutment element 160 is a second part of the first damping element 130. In this case, the second part and the first part 131 are a single piece.
[0107] Alternatively, the attachment devices between the support base 10 and the housing 200 may be different in both number and type.
[0108] Alternatively or additionally, the at least one damping system 100 is configured to include Figure 5 and Figure 6 The third damping element 145 is shown. The third damping element 145 is adapted to elastically deform along the loading direction to switch from a lower deformation configuration to a higher deformation configuration. The third damping element 145 is fixedly positioned above the wall of the support base 10. The wall 11 of the support base 10 is the wall 210 facing the housing 200. The height of the third damping element 145 is lower than the height of the portion 131 of the first damping element 130 extending outside the receiving seat 110. This height is measured along a direction parallel to the loading direction. Advantageously, when the bicycle or motorcycle 200 experiences a strong impact causing the housing 200 to elastically deform the first damping element 130 until the height of the first damping element 130 decreases to the level of the second damping element 140, the third damping element 145 operates to further dampen the impact through elastic deformation.
[0109] According to the first preferred alternative, at least one third damping element 145 is positioned above the wall 11 of the support base 10. Even more preferably, there are three third damping elements 145 positioned on the wall 11 at 120 degrees to each other.
[0110] According to Figure 7 In the second preferred alternative shown, the third damping element 145 may have an annular shape and be fitted around the first damping element 130.
[0111] According to the third preferred alternative, as mentioned above and in Figures 1 to 4 As seen in the previous description, the second damping element 140 can be accommodated in the receiving seat 110, and as in the previously described alternatives and in Figures 5 to 7 As shown in the figure, the third damping element 145 can be positioned above the wall 11 of the support base 10.
[0112] Alternatively or otherwise, such as Figure 8 As shown, the at least one damping system 100 includes a fourth damping element 146, which is adapted to elastically deform along the loading direction to switch from a lower deformation configuration to a higher deformation configuration.
[0113] At least one of the attachment devices 12 is fixed to the support base 10 by means of the at least one fourth damping element 146.
[0114] like Figure 8 As shown, for example, one of the attachment devices 12 is a stud, and is fixed to the support base 10 by means of two fourth damping elements 146.
[0115] Alternatively or additionally, the mushroom-shaped attachment device 12 shown in the figures can be fixed to the support base 10 by means of a single fourth damping element 146.
[0116] Preferably, the third damping element 145 and the fourth damping element 146 have the same features described for the second damping element 140. From the above description, the features of the device for which this invention is intended are clear, and the related advantages are also clear.
[0117] Finally, it is clear that the device conceived in this way is readily modified and varied, all of which fall within the scope of this invention; furthermore, all details can be replaced by technically equivalent elements. In practice, the materials and dimensions used can be any materials and dimensions depending on the technical requirements.
