Description

Field of the invention

[0001] The present invention relates to a shock absorption structure and, more particularly, to a structure for absorbing impact forces and increasing the comfort of a seat cushion and for use in saddle-related applications such as bicycles, exercise bikes, wheelchairs, office chairs, etc. State of the art

[0002] Seatposts are commonly found in products such as bicycles, exercise bikes, wheelchairs, and office chairs, and primarily serve to connect a seat cushion mounted on them, upon which the user sits. In the case of a bicycle seatpost, it is typically located within the seat tube of a bicycle frame. Their primary functions are to support the rider's body weight, absorb impact forces transmitted from the ground, and secure the rider's position while pedaling. Depending on the desired effect, they can also provide additional features such as shock absorption, height adjustment, fore / aft adjustment, and tilt adjustment. Therefore, different designs and technologies for seatposts have been developed over time.

[0003] It's important to note that bicycle seatposts with shock absorption functions must simultaneously absorb and dampen both the pressure from the rider's body weight and the impact forces transmitted from the ground via the seat tube. Therefore, commercially available bicycle seatposts typically have a shock absorption structure built into bicycle components such as the saddle, seat post, or seat tube.

[0004] A conventional seatpost structure with a shock-absorbing function involves arranging a buffer assembly within a seatpost or seat tube. An elastic element is arranged in the buffer assembly to absorb pressure and subsequently return the associated components to their original positions. Such conventional techniques are disclosed, for example, in Taiwanese Utility Model Publication No. 112207651, entitled "Improvement of a Shock-Absorbing Seatpost," and in Taiwanese Utility Model Publication No. 112202747, entitled "Height-Adjustable Seatpost with Shock-Absorbing Function."

[0005] Another conventional seatpost structure with a shock-absorbing function provides a cushioning assembly beneath a saddle, with at least one elastic member disposed between the saddle and two lower support rods or inside the saddle. When the elastic member is compressed by gravity from above or by an impact force from below, the elastic member is compressed and returns to its original state after the pressure is released. Such conventional techniques are disclosed, for example, in Taiwanese Utility Model Publication No. 112206158 entitled "Shock-Absorbing Bag Filled with Damping Particles and Saddle Combined Therewith" and Taiwanese Utility Model Publication No. 108107107 entitled "Saddle with Shock-Absorbing Body and Manufacturing Method Therewith."

[0006] In addition, there is also a conventional technology of a connecting rod-type shock-absorbing seat post in which a connecting rod structure is arranged on seat clamp assemblies and a seat post and can pivot forward or backward when a force is applied and is returned to its original position by means of an elastic member or a buffer rod after the pressure is released.

[0007] Such a conventional connecting rod-type shock-absorbing seat post is disclosed, for example, in Taiwanese Utility Model Publication No. 113211878 entitled "Improvement of a connecting rod-type shock-absorbing seat post." It includes: a seat post having a tubular body; a main bracket that can be fitted onto the seat post and has a through hole connected to the tubular body; a connecting seat that serves for pivotal connection to a bicycle seat; at least one first connecting rod located at the front end of the seat post and between the main bracket and the connecting seat, and pivotally connected thereto; at least one second connecting rod located at the rear end of the seat post and between the main bracket and the connecting seat, and pivotally connected thereto.a buffer component disposed in the through hole, the upper end of the buffer component protruding from the through hole and located between the first and second connecting rods; and a pressing and abutting component disposed between the first connecting rod and the buffer component, comprising a main body, one end of the main body being pivotally connected to the first connecting rod via a pivot portion, and the other end of the main body having at least one pressing and abutting portion that is in contact with the upper end of the buffer component in the normal state.

[0008] Another conventional technology of a connecting rod-type shock-absorbing seat post is disclosed, for example, in Taiwanese Utility Model Publication No. 113211689 entitled “Shock-Absorbing Seat Post.”It comprises a connecting rod component and an elastic element, wherein the connecting rod component comprises connecting joints distributed at four corners, which joints together define a receiving space whose size is variable, the elastic element consists of two interlocking curved elastic blocks, each curved elastic block having a first curved end, a second curved end and a concave belly side and a convex back side located between the first curved end and the second curved end, the first curved end of one curved elastic block is engaged with the concave belly side of the other curved elastic block and the two curved elastic blocks in this locked state are then inserted together into the receiving space.In addition, coordinated limiting elements are provided between the two curved elastic blocks and the receiving space so that the two curved elastic blocks can be inserted into the receiving space and limited in their positions and protected from falling out.

[0009] Yet another conventional technology of a connecting rod-type shock-absorbing seat post is disclosed, for example, in Taiwanese Utility Model Publication No. 112210370 entitled "Shock-Absorbing Seat Post." It includes a tubular body; a connecting rod assembly disposed at the upper end of the tubular body and defining a variable-size or variable-shape space inside the tubular body; and an elastic member that is in a first compression state within the space defined by the connecting rod assembly and assumes a second compression state when the size or shape of the space changes. Object of the invention

[0010] The above conventional "connecting rod" shock-absorbing seatposts each have a pair of connecting rod seats, one end of each connecting rod seat pivotally connected to a seat clamp assembly, and the other end of each connecting rod seat pivotally connected to the upper portion of a seatpost. The technical differences between the above-mentioned cases lie in the shock absorption and return mechanisms. In the first conventional case, return is achieved by a spring arranged below a seatpost and combined with an axle rod. The return force of the spring returns a connecting rod combined with the axle rod to its original position. In the second and third conventional cases, an elastic member is arranged between the connecting rod seats.When the connecting rod seats are pivoted by external forces, the elastic element is deformed and, after the pressure is released, a restoring force is generated which returns the connecting rod seats to their original positions.

[0011] Although the recovery speed of the above conventional connecting rod-type shock-absorbing seatposts, especially those of the second and third cases, is better than that of the first case, there is still room for improvement in terms of recovery speed and sensitivity. Furthermore, due to their material properties, the elastomers used in the second and third cases are prone to shrinkage, falling out of the space between the connecting rod seats, or even complete separation during riding due to impact after prolonged outdoor use and exposure to wind, rain, and sunlight, resulting in a shortened service life. The shock absorption capacity of the conventional connecting rod-type shock-absorbing seatposts also has room for improvement. Therefore, the inventor provides a connecting rod-type shock-absorbing seatpost that can effectively solve the above-mentioned problems in the prior art. (Technical means of problem solving)

[0012] The connecting rod-type seat post shock absorbing structure according to the invention comprises a shock absorbing device located between a seat post assembly and a clamping device, which comprises at least one pair of connecting rod seats which are at a predetermined distance from each other, wherein one end of each connecting rod seat is pivotally combined with the seat post assembly and the other end is pivotally combined with the clamping device, wherein cover recesses are provided at the mutually corresponding positions of the two connecting rod seats, wherein a shock-absorbing elastomer is arranged between the connecting rod seats and is covered and positioned thereby and is provided integrally with two projecting cover sections which are arranged at the positions corresponding to the cover recesses,Each cover section is completely housed in the corresponding cover recess and rests against the wall of the corresponding cover recess, engaging with the corresponding cover recess, and thus positioned. The components described above, along with a cover design provided between a respective connecting rod seat and the shock-absorbing elastomer, result in a large-area, complete contact connection, making the force transmission between the components more direct and faster, improving both the damping speed and the recovery speed and sensitivity. At the same time, the form-fitting structure of the cover recesses and the cover sections increases the covered area of ​​the shock-absorbing elastomer, which not only further improves the damping speed, the recovery speed, and the sensitivity,It also ensures a positioning function. This prevents the shock-absorbing elastomer from detaching from the connecting rod seats, reduces maintenance requirements, and extends service life. The overall structure is thus suitable for industrial use. (Comparison with the advantageous effects of the state of the art)

[0013] The main object of the present invention is to provide a connecting rod-type seat post shock absorbing structure in which a cover design is provided between each connecting rod seat and the shock absorbing elastomer, wherein the connecting rod seats abut against the shock absorbing elastomer and a relatively large volume fraction of the shock absorbing elastomer can be covered by the two connecting rod seats, so that the force acting on the connecting rod seats is quickly transmitted to the shock absorbing elastomer and thus the damping speed and sensitivity are improved.

[0014] Another object of the present invention is to provide a connecting rod-type seat post shock absorbing structure in which a cover design is provided between each connecting rod seat and the shock-absorbing elastomer, wherein the connecting rod seats abut against the shock-absorbing elastomer, and a relatively large volume fraction of the shock-absorbing elastomer can be covered by the two connecting rod seats. When the connecting rod seats are pivoted due to compressive load, thereby deforming the shock-absorbing elastomer, the shock-absorbing elastomer can automatically and quickly return to its original state after the pressure is released. Due to the large-area contact between each connecting rod seat and the shock-absorbing elastomer, the respective connecting rod seats are synchronously returned to their original positions, thereby improving the recovery speed and sensitivity.

[0015] A still further object of the present invention is to provide a connecting rod-type seat post shock absorbing structure in which a respective connecting rod seat and the shock absorbing elastomer are engaged with each other via recesses and projections whose abutting areas are relatively large, so that the covered area of ​​the shock absorbing elastomer is further increased and thus the damping and restoring effect in terms of speed and sensitivity is further improved.

[0016] A further object of the present invention is to provide a connecting rod-type seat post shock absorbing structure in which a respective connecting rod seat and the shock-absorbing elastomer engage with each other via recesses and projections whose abutting surfaces are relatively large, which not only further increases the covered area but also prevents the shock-absorbing elastomer from detaching from the connecting rod seats due to accidents or slight shrinkage. Thus, the present invention offers high practicality.

Detailed description of the embodiment

[0017] It is based on the Fig. 1 to 4. The connecting rod-type seat post shock absorbing structure according to the invention primarily comprises a seat post assembly (10), a clamping device (20) attached to the seat post assembly (10), and a shock absorbing device (30).

[0018] The seat post assembly (10) is arranged within a bicycle seat tube and comprises a long tubular seat post (11) at the upper end of which a seat post head seat (12) is arranged, wherein the seat post head seat (12) is provided with a seat post contact section (121) having an arcuate region and is formed integrally with two projecting pivot connection seats (122), (123) which are arranged at a predetermined distance from one another.

[0019] The clamping device (20) serves to provide a clamping and fastening section for a saddle (60) and has a clamping base (21), wherein two clamping assemblies (22), (23) are arranged on two sides of the clamping base (21) and each have a first clamping seat (221), (231) and a second clamping seat (222), (232), which respectively clamp and position the combination rods (61) arranged under the saddle (60) therein, wherein the first clamping seats (221), (231) are partially accommodated in the clamping base (21) and the second clamping seats (222), (232) are arranged outside the clamping device (20). The clamping arrangements (22), (23) and the clamping base (21) are combined with one another along an axis by a combination rod (24), wherein the combination rod is guided from one side of one of the second clamping seats (222), (232) successively through a second clamping seat (222) or (232), a first clamping seat (221) or(231), the clamping base (21) and the other first clamping seat (221) or (231), and finally, the through-end of the combination rod (24) is screwed into the other second clamping seat (222) or (232) and positioned therein. Furthermore, a clamping contact section (211) having an arcuate region is provided on the clamping base (21).

[0020] The shock absorbing device (30) is arranged between the seat post head seat (12) and the clamping device (20) and comprises at least a pair of connecting rod seats (31), (32) which are at a predetermined distance from one another, wherein one end of each connecting rod seat is pivotally connected to the seat post head seat (12) and the other end is pivotally connected to the clamping base (21), wherein cover recesses (311), (321) are provided at the mutually corresponding positions of the two connecting rod seats (31), (32), wherein a shock absorbing elastomer (33) is arranged between the connecting rod seats (31), (32) and is covered and positioned thereby and is provided integrally with two projecting cover sections (331), (332) which are arranged at the positions corresponding to the cover recesses (311), (321), wherein each cover section (331), (332) completely in the corresponding cover recess (311),(321) is housed and rests against the wall of the corresponding cover recess (311), (321) and engages with the corresponding cover recess (311), (321) and is thus positioned. A respective cover section (331), (332) extends radially from one side of the shock-absorbing elastomer (33) up to a certain height and occupies at least half of the arcuate region of the side surface of the shock-absorbing elastomer (33). In the region of the shock-absorbing elastomer (33) opposite the seat post contact section (121), a protruding seat post contact edge (333) is formed in one piece, which rests against the seat post contact section (121), wherein the seat post contact edge (333) and the seat post contact section (121) abut one another via their curved structures. In the area of ​​the shock-absorbing elastomer (33) opposite the clamping base (21), a projecting clamping edge (334) is formed in one piece,wherein the projecting clamping edge and the clamping section (211) abut each other via their curved structures.

[0021] Each connecting rod seat (31), (32) has an inverted U-shaped pivot connection recess (312), (322) at one end, wherein a respective projecting pivot connection seat (122), (123) is accommodated in the corresponding pivot connection recess (312), (322). A pivot connection rod (34) is passed through a respective pivot connection recess (312), (322) and the corresponding projecting pivot connection seat (122) or (123), whereby both components are combined and positioned with each other in order to hold the connecting rod seats (31), (32) in a rotatable state. A locking groove (341) is formed circumferentially in a predetermined central portion of each pivot connection rod (34).After passing a respective pivot connecting rod (34) through the corresponding pivot connecting recess (312), (322) and the corresponding projecting pivot connecting seat (122), (123), a positioning bolt (35) is passed radially through a respective projecting pivot connecting seat (122), (123), wherein the insertion end of a respective positioning bolt (35) engages in the corresponding locking groove (341).

[0022] The clamping base is provided in one piece with two protruding pivot connection seats (212), (213). Each connecting rod seat (31), (32) has an inverted U-shaped pivot connection recess (313), (323) at the other end, wherein each protruding pivot connection seat (212), (213) is accommodated in the corresponding pivot connection recess (313), (323). A pivot connection rod (36) is passed through each pivot connection recess (313), (323) and the corresponding protruding pivot connection seat (212) or (213), whereby both components are combined and positioned to hold the connecting rod seats (31), (32) in a rotatable state. A respective projecting pivot connection seat (212), (213) is further provided with an inverted U-shaped recess (214), wherein a combination element (37) is arranged in a respective recess (214).A locking groove (361) is formed circumferentially in a predetermined central section of each pivot connecting rod (36). After each pivot connecting rod (36) is passed through the corresponding pivot connecting recess (313), (323), the corresponding combination element (37), and the corresponding projecting pivot connecting seat (212), (213), a positioning pin (38) is passed radially through the corresponding combination element (37), whereby the insertion end of each positioning pin (38) engages the corresponding locking groove (361).

[0023] Alternatively, another pivot connection construction can be used, in which a respective pivot connection rod (39) consists of two screw elements (391), (392), wherein one screw element (391) is passed from one side through the corresponding pivot connection recess (313), (323) and the corresponding projecting pivot connection seat (212), (213) and the other screw element (392) is passed from the other side through the corresponding pivot connection recess (313), (323) and the corresponding projecting pivot connection seat (212), (213) and then the insertion end of the screw element (391) is screwed to the insertion end of the screw element (392).

[0024] The components described above and the cover design provided between each connecting rod seat (31), (32) and the shock-absorbing elastomer (33) result in a large-area, full contact connection, whereby the force transmission between the components is more direct and faster, which improves both the damping speed and the recovery speed and sensitivity. At the same time, the form-fitting structure of the cover recesses (311), (321) and the cover sections (331), (332) enlarges the covered area of ​​the shock-absorbing elastomer (33), which not only further improves the damping speed and the recovery speed and sensitivity, but also ensures a positioning function. This prevents the shock-absorbing elastomer (33) from detaching from the connecting rod seats (31), (32), reduces maintenance requirements, and extends the service life.The overall structure is therefore suitable for commercial use.

[0025] To further clarify the structural features, the technical means used and the desired advantageous effects of the present invention, its method of use is described below:

[0026] In assembling the present invention, first, the seat post head seat (12) is attached to the upper end of the seat post (11). A respective connecting rod seat (31), (32) is combined with the corresponding projecting pivot connection seat (122), (123) by means of the corresponding pivot connection recess (312), (322). A respective pivot connection rod (34) is sequentially passed through the corresponding pivot connection recess (312), (322) and the corresponding projecting pivot connection seat (122), (123), and then a respective positioning bolt (35) is passed through the corresponding projecting pivot connection seat (122), (123), whereby its insertion end engages the corresponding locking groove (341) to position the associated components. Subsequently, the pivot connection recess (313) of the connecting rod seat (31) is combined with the protruding pivot connection seat (213) of the clamping base (21).Next, a two-part pivot connecting rod (39) is passed through the pivot connecting recess (313) and the protruding pivot connecting seat (213) from one side by means of its screw element (391). Subsequently, the other screw element (392) is passed through the pivot connecting recess (313) and the protruding pivot connecting seat (213) from the other side, and then the insertion end of this screw element (391) is screwed to the insertion end of the screw element (392).Subsequently, the pivot connection recess (323) of the connecting rod seat (32) is combined with the projecting pivot connection seat (212) of the clamping base (21), wherein a combination element (37) is arranged in a respective recess (214), wherein a pivot connection rod (36) is successively passed through the pivot connection recess (323), the projecting pivot connection seat (212) and the corresponding combination element (37) and then a positioning bolt (38) is radially passed through the corresponding combination element (37), whereby the insertion end of a respective positioning bolt engages in the corresponding locking groove (361).

[0027] The shock-absorbing elastomer (33) is housed in the space formed jointly by the connecting rod seats (31), (32), the clamp base (21), and the seat post head seat (12). The cover sections (331), (332) located on two sides are each inserted into the corresponding cover recesses (311), (321), with the lower seat post contact edge (333) resting against the seat post contact section (121) and the clamp contact edge (334) resting against the clamp contact section (212). The shock-absorbing elastomer (33) is thus completely enclosed by the four components, namely the connecting rod seats (31), (32), the clamp base (21), and the seat post head seat (12).

[0028] When assembling the clamping device (20), the first clamping seats (221), (231) located on two sides are first partially accommodated in the clamping base (21), with a respective second clamping seat (222), (232) located outside the corresponding clamping arrangement (22), (23). The clamping arrangements (22), (23) and the clamping base (21) are connected to one another along an axis by a combination rod (24), wherein the combination rod is passed from one side of the second clamping seat (232) successively through the second clamping seat (232), the first clamping seat (231), the clamping base (21) and the first clamping seat (221) and finally the through-end of the combination rod (24) is screwed into the second clamping seat (222), thus completing the assembly.

[0029] It will be Fig. 5. When the rider's body weight acts on the present invention, the connecting rod seats (31), (32) are pivoted backwards towards the seat post (11) when the saddle (60) is subjected to pressure by the rider's body weight, whereby the shock-absorbing elastomer (33) located between the connecting rod seats (31), (32) is gradually compressed and deformed by the connecting rod seats (31), (32) due to the changed spatial geometry. After the pressure on the saddle (60) is relieved, the shock-absorbing elastomer (33) automatically generates a restoring force due to its inherent elasticity, which causes the connecting rod seats (31), (32) to pivot synchronously forwards again towards the seat post (11) until the connecting rod seats (31), (32) have resumed their original positions.

[0030] It will be Fig.6. When the present invention is subjected to an impact force originating from the ground and the impact force is transmitted via the wheels to the frame and then upwards to the seat post (11), the connecting rod seats (31), (32) are pivoted to the front or rear side of the seat post (11), whereby the shock-absorbing elastomer (33) located between the connecting rod seats (31) (32) is gradually compressed and deformed by the connecting rod seats (31), (32) due to the changed spatial geometry. After the impact force is removed, the shock-absorbing elastomer (33) automatically generates a restoring force due to its inherent elasticity, which causes the connecting rod seats (31), (32) to gradually pivot back synchronously in the opposite direction until the connecting rod seats (31), (32) have resumed their original positions.

[0031] The present invention uses a cover design with a sufficiently large contact surface between a respective connecting rod seat (31), (32) and the shock-absorbing elastomer (33), thereby achieving the following advantageous effects: 1. In the present invention, a relatively large volume fraction of the shock-absorbing elastomer (33) is covered by the connecting rod seats (31), (32), wherein the connecting rod seats (31), (32) are in direct contact with the shock-absorbing elastomer (33), thereby enabling more direct force transmission and thus allowing the force to be transmitted more quickly to the shock-absorbing elastomer (33) for damping. Therefore, the present invention has superior damping speed and sensitivity compared to the conventional technology. 2. Due to the complete coverage and the large contact surface between each connecting rod seat (31), (32) and the shock-absorbing elastomer (33), the restoring force of the shock-absorbing elastomer (33) can be transmitted more quickly to the connecting rod seats (31), (32), thereby returning the connecting rod seats (31), (32) to their original positions. Therefore, the present invention exhibits superior restoring speed and sensitivity compared to the conventional technology. 3. Due to the positive-locking structure of the cover recesses (311), (321) and the cover sections (331), (332) between a respective connecting rod seat (31), (32) and the shock-absorbing elastomer (33), the covered area of ​​the shock-absorbing elastomer (33) can be further enlarged, thereby further improving the damping and restoring effect in terms of speed and sensitivity. 4. The form-fitting structure of the cover recesses (311), (321) and the cover sections (331), (332) not only further increases the covered area of ​​the shock-absorbing elastomer, but also prevents the shock-absorbing elastomer from detaching from the connecting rod seats (31), (32) due to accidents or slight shrinkage. This reduces maintenance costs, extends service life, and ensures maximum practicality. Thus, the present invention effectively solves the problems of conventional elastomers such as accidental detachment, shrinkage, frequent repairs, and short service life. 5. In the present invention, the shock-absorbing elastomer (33) has a one-piece structure with the cover portions (331), (332), the seat post abutment edge (333), and the clamp abutment edge (334), each formed as a protrusion. This simplifies the overall structure, facilitates and speeds up assembly, and effectively reduces production costs. 6. The shock-absorbing elastomer (33) is provided on its upper side with the protruding clamping edge (334), the outer shape of which is matched to the shape of the clamping section (211), so that the upper side of the shock-absorbing elastomer (33) can bear against the clamping section (211) over a large area, which further increases the covered area of ​​the shock-absorbing elastomer (33) and further improves the damping and restoring effect in terms of speed and sensitivity. 7. The shock-absorbing elastomer (33) is provided on its underside with the protruding seat post contact edge (333), the outer shape of which is matched to the shape of the seat post contact section (121), so that the underside of the shock-absorbing elastomer (33) can bear against the seat post contact section (121) over a large area, which further increases the covered area of ​​the shock-absorbing elastomer (33) and further improves the damping and restoring effect in terms of speed and sensitivity.

[0032] It is worth noting that in the present invention, the clamping device is not limited to the lateral connection of the clamping seats described in the exemplary embodiment, but can also be used for other arrangements with vertically arranged clamping seats. The clamping device comprises a clamping arrangement arranged above the clamping base and having an upper clamping seat and a lower clamping seat, which can clamp and position the two combination rods (61) located below the saddle (60) therein.

[0033] In summary, the present invention discloses a "connecting rod type seatpost shock absorbing structure" that provides a cover design for the shock-absorbing elastomer and the connecting rod seats. The cover portions of the shock-absorbing elastomer located on two lateral sides and the cover recesses are in close contact with each other, while the upper and lower sides of the shock-absorbing elastomer are in extensive contact with the clamp base and the seatpost head seat, respectively. This enables a more direct and faster transmission of impact force, gravity, and restoring force, further improving the damping and restoring effect in terms of speed and sensitivity. At the same time, the shock-absorbing elastomer can be positioned to minimize the occurrence of detachment and reduce maintenance costs.Furthermore, the one-piece molding of the cover sections and the contact sections enables a reduction in manufacturing and assembly costs. Overall, the present invention offers high industrial applicability and economic efficiency. Since the structure of the present invention has not been disclosed in any known publication or application, it meets the requirements for a utility model application. The application is filed in accordance with the law.
