Description

The present invention relates to a saddle storage device having a saddle connection member adapted for connecting saddle posts of a saddle on which a person can sit with the saddle storage device, and a frame connector configured to connect the saddle storage device to a frame or seat post, such as a patent seat post which is connectable or connected to a frame of a sports equipment, such as a training device, a motion simulating bicycle, such as home exercisers, ergometers, bicycles or generally a two-wheeler. The saddle bearing device can thus be inserted between the saddle and frame or patent seat post of a bicycle or sports equipment.

A saddle forms a seat support for a person driving a two-wheeler, for example. To connect the saddle to a frame of a sports equipment, a patent seat post is often used which has a tube which can be inserted into the frame and which establishes a connection between the saddle and the frame. To increase comfort when driving seat posts are also known, which have a suspension that springs when driving through bumps in the road resulting shocks and possibly damps.

The object of the invention is to provide a saddle storage device of the type described above, with a movement of the saddle relative to the frame about three pivot axes is possible, and which is characterized by a simple assembly between the saddle and frame.

This object is achieved by a saddle storage device according to claim 1. In a stationary to be used sports equipment, the direction of travel corresponds to a viewing direction of a person sitting on the saddle, or a straight-ahead direction of the saddle. A first axis of rotation may be arranged so as to be inclined in use vertically or slightly, approximately 5 °, 10 ° or 20 ° counter to the direction of travel, being arranged in a vertical plane lying in the direction of travel.

A second axis of rotation may be arranged to point in the direction of travel in use and extend horizontally, and a third axis of rotation may be arranged to be transverse to the direction of travel in use and to extend horizontally.

The frame connecting element preferably comprises one, two or more, in particular parallel attachment struts, which correspond in shape and arrangement to the saddle struts of a commercially available saddle. Each attachment strut may have a diameter of 6 to 9, preferably 7 to 8 mm. A center distance of the fastening struts may be 42 to 46 mm, preferably 43.5 to 44.5 or 44 mm. The axes of rotation of the bearing member allow a saddle connected to the saddle connector of the invention to perform a multi-axis pivotal movement relative to the frame during use or driving of a sports device or bicycle provided with the saddle bearing device. As a result, additional muscle groups are claimed. In addition, when driving through bumps in a roadway resulting shocks can be better damped, since the possibility of a non-linear movement creates an additional margin for the interception of the shocks. Furthermore, a shoulder view is simplified due to the vertical axis of rotation and thereby increases the safety when driving a bicycle or two-wheeler. In addition, a balancing with a two-wheeler in a small space is possible, since a use of the hip is possible.

The all-round rotation around three mutually perpendicular axes of rotation, the saddle movement is evened, whereby the stress on additional muscle groups and the ability to dampen shocks is further improved. Each rotation axis may be assigned a predetermined largest rotation angle range, for example. At most - / + 10 °, 20 °, 30 °, for example, based on a predetermined rest position. Each axis of rotation can be associated with a progressively stronger restoring force, for example by means of a respective return spring. By means of a fixed or resilient stop to the fixed or progressively resilient boundary of the rotation angle range, an individual stop can be defined with respect to each axis of rotation.

Preferably, the bearing element has a ball joint. The ball joint may include a ball and a rotatably receiving condyle. A bolt may be disposed on the ball.

Furthermore, the restoring element may comprise a projection and a corresponding counter element, between which an elastic element, preferably an elastomer element, may be held. In this case, the projection and the counter-element can be arranged so that upon a deflection of the saddle from the rest position of the projection presses the elastic element against the counter element.

The projection and / or the counter-element may be formed from an elastic material (for example steel spring and / or elastomer) or a rigid material.

The projection may also have a first surface orthogonal to the first axis of rotation. In this case, the protrusion is moved with the first surface against the counter-element when the saddle is deflected about the second and / or third axis of rotation from the rest position. In addition, the projection may have a second surface orthogonal to the second and third axes of rotation. In this case, the projection can be moved with the second surface against the counter element when the saddle is deflected about the first axis of rotation from the rest position.

The projection is preferably round, oval, plate-shaped, polygonal, cross-shaped or T-shaped in cross section in the viewing direction along the longitudinal direction of the projection.

The saddle device may also have a plurality of projections which may be associated with one or more counter-elements in different orientations. Thus, each protrusion can form at least one surface which is moved against the respective counter element when the saddle is deflected out of the rest position.

The counter-element may comprise a housing for receiving an elastic element enclosed therein, which has a recess for receiving the projection.

The projection may be fixedly connected to the frame connector or the saddle connector and / or the counter member may be fixedly connected to the saddle connector or the frame connector.

It can also be provided that the third return action during a movement of the Saddle connecting element or a saddle connected to the second axis of rotation to the front, wherein a front portion of the saddle is lowered and a rear portion of the saddle is raised, is less pronounced, as a restoring action with respect to a rotational movement about the second axis of rotation in the reverse direction with the rear part of the saddle lowered and the front part raised. As a result, a tilting movement of the saddle is counteracted to the rear in an increased degree.

Each of said restoring effects may be either spring-like, wherein a restoring force is proportional to the angular displacement about the respective axis of rotation, or progressive, wherein a restoring force is stronger than linear with respect to a deflection about the axis of rotation, for example square or according to a polynomial law. It can be provided that the restoring action initially comprises a fixed dead zone, wherein within a predetermined angular range of a deflection about the respective axis of rotation starting from the rest position there is no restoring effect and a restoring force acts only after exceeding the dead zone.

The saddle storage device 14 also has a down along an edge 20a open spherical outer shell 20 and an internal ball joint 44 on, which forms a bearing element and the saddle connection element 16 relative to the frame connector 36 around the center of a sphere 48 of the ball joint 44 rotatably supported on all sides. The outer shell 20 serves the cover of the ball joint and is with the ball 48 connected. Outside the outer shell 20 are two fasteners 22 in the form of clamping parts of a semi-trailer with a bolt 8th at the ball 48 attached, each having two terminal points. The ball joint allows rotation of the saddle connector 16 and the saddle 12 relative to the frame connector 36 around a first vertical axis of rotation 6 , a second horizontal, in the direction of travel 2a extending axis of rotation 2 and a third horizontal, transverse to the direction of rotation axis of rotation 4 , All axes of rotation intersect at the center of the sphere 48 , The bolt 8th passes through the ball 48 and along the second axis of rotation 4 ,

By means of an upper one of the two clamping points are two parallel seat stays 24 of the saddle 12 at the ball 48 attached. The saddle struts 24 form together with a seat 26 and a (polymer) suspension 28 attached to a rear end of the seat stays 24 is arranged and the seat 26 of the saddle 12 relative to Saddle Rack 24 supports the saddle 12 , The seat 26 of the saddle 12 may further comprise a cover made of natural material or plastic and in particular of a synthetic fabric, which is stretched over a molding element, by the suspension 28 and the saddle struts 24 is supported. Furthermore, a padding may be provided between the cover and the molded element.

By means of the respective other, lower clamping points of the connecting elements 22 are two fixing straps 30 with the ball 48 connected. The fixing bracket 30 can run horizontally or, as in 1 shown having a curved from the side shape or a slight S-shape with a rising rear end and a sloping front end and at each end with a return element, in particular the spring elements shown 32 be connected. The fixing bracket 30 be through the (tension) spring elements 32 , which in turn with their other ends in pairs front and back of the frame connector 36 are fixed, held relative thereto in a horizontal rest position. The spring elements 32 are preferably biased. The paired arrangement of the spring elements, left and right and front and rear, causes restoring forces in the direction of the horizontal rest position of the saddle with respect to the second and third axis of rotation 2 . 4 and also in relation to the first axis of rotation 6 , By fixing the Fixierbügel 30 at the ball 48 thus becomes the saddle 12 relative to the frame connector 18 kept in a quiet location.

The the ball 48 about three axes or universally rotatable receiving condyle 46 of the ball joint 44 is by means of a threaded rod 34 with the frame connector 36 connected to which the spring elements 32 are attached. The movement or swivel range of the ball 48 and thus the saddle connection element 16 relative to the frame connector 36 or relative to the threaded rod 34 can through the outer shell 20 and an internally threaded, on the threaded rod 34 adjustable limiting element 38 limited by a blocking bolt 40 at different distances from the outer shell 20 or its edge 20a can be fixed and at a certain deflection angle comes into contact with the outer shell and blocks further pivoting.

2 shows a partial section of a second embodiment of a saddle storage device 14 (Saddle not shown). The saddle storage device 14 includes, like those in 1 shown saddle bearing device, as a bearing element a ball joint 44 with hollow condyle 46 and ball held in it 48 , one with the condyle 46 of the ball joint 44 connected threaded rod 34 and one with the threaded rod 34 connected frame connector 36 , which is intended for connection to a commercial patent seat post. One along or parallel to the third axis of rotation 4 extending bolt 8th reaches through the ball 48 and holds distance bushings 8a and fasteners 22 on which the seat stays 24 are attached, with the bolt 8th with a mother 8b works together. An outer shell 20 , inside which are the fasteners 22 are stuck with the ball 48 connected.

Furthermore, the saddle storage device comprises 14 as in 1 a threaded adjustable limiting element 38 and a locking pin (not shown) fixing the position thereof. Furthermore, different from the in 1 shown saddle storage device 14 the spring elements which the saddle connection element 16 relative to the frame connector 36 in a rest position, in the down along an edge 20a open outer shell 20 integrated. In particular, one of the spring elements 50 as a spiral spring or torsion spring, as a (cone) compression spring 50 formed between an upper bearing, such as an axial thrust bearing 52 and a lower bearing, such as an axial thrust bearing 54 , which may comprise in particular thrust ball bearings, axial needle or axial tapered roller bearings, rotatably mounted.

To regulate the preload of the torsion or compression spring 50 can the distance between the upper bearing, here the axial thrust bearing 52 , and the lower bearing, here the axial thrust bearing 54 , By means of a spring adjusting element in the form of a threaded rod 34 adjustable knurled nut 56 can be adjusted, which on rotation, the lower axial thrust bearing 54 in the direction of the upper axial thrust bearing 52 or away from it and by means of a fixing bolt 58 can be fixed in a desired position. To hold the saddle connector 16 relative to the frame connector 36 in a rest position alternatively (steel) tension springs can be provided, which the condyle 46 with the outer shell 20 or the ball 48 connect and this at a deflection of the condyle 46 around a rotation axis the condyle 46 apply a restoring force counter to the rotation. Such a tension spring 60 is shown as an example.

To prevent the edge 20a the opening of the outer shell 20 directly on the boundary element 38 or the threaded rod 34 is on the edge 20a and on the boundary element 38 a rubber boot or a bellows 62 attached, the nip as a potential danger point between the edge of the opening 20a and the delimiter 38 or the threaded rod 34 covered and thus secured.

3 shows a partially sectioned side view of a third embodiment of a saddle storage device 14 , A saddle 12 is over saddle struts 24 on fasteners 22 in the form of a known Sattelklobens, which is a saddle connector 16 form, on the saddle storage device 14 attached. Analogous to the execution according to 2 reaches through a bolt 8th two each on one side connecting elements 22 , a spacer 8a on each side as well as a ball 48 , in turn, in a condyle 46 is mounted and forms the bearing element, which is a pivoting of the saddle 12 about three axes of rotation relative to a frame connector 36 allows, as described in the second embodiment.

A rigid outer shell 20 made of sheet steel or similar is through the bolt 8th firmly connected to the saddle and covers the condyle 46 as well as other parts of the saddle storage device 14 from. Unlike the embodiment according to 2 extends the outer shell 20 in relation to the condyle 46 in the direction of travel further forward and backward and also to the left and right to four tension springs 32 take up the between the frame connector 36 or the threaded rod 34 and the outer shell 20 are arranged and are in the rest position of the saddle device in a plane which is parallel to the respective horizontally extending second and third axis of rotation 2 . 4 is arranged. The arrangement of the springs 32 is thus functionally analogous to the embodiment according to 1 However, the springs, however, in the in 3 shown rest position in the said plane and extend with outer ends on the outer shell 20 are attached and not like in 1 on a fixing bracket.

The feathers 32 thus extend in a horizontal plane in an X-shaped arrangement, being at outer ends on the outer shell 20 and thus on the saddle connection element 16 and at inner ends via a fastener 70 on the frame connector 36 are held. The feathers 32 are adjustable with respect to their effective length with the outer shell 20 connected, wherein a spring adjusting element in the form of an adjusting screw 72 and a co-operating with this carriage 74 is provided, wherein a distance of the carriage 76 from the connecting element 70 or from the frame connector 36 by turning the adjusting screw 72 can be adjusted. The sled 74 is in a leadership 76 guided against rotation. Although for every single feather 32 an adjustment screw 72 and a sled 74 could be provided, the embodiment looks after 3 prefers that the Einstellschlitten 74 in the direction of the third axis of rotation 4 , ie transverse to the direction of travel, extending and at its ends in each case an end of a spring 32 wearing. In this case, there is one adjusting screw each 72 front and rear of the saddle storage device 14 so with each adjusting screw 72 both springs 32 can be adjusted together front and rear. 5a, b show more details on this.

A delimiter 38 that may be tapered or stepped as shown is on the frame connector 36 or the threaded rod 34 arranged height-adjustable and limits the deflection about the second and third axis of rotation 2 . 4 , In addition, it prevents direct contact of the outer shell 20 with the threaded rod or the frame connecting element. A rubber cuff 62 is by means of screw or plug-in connection elements 62a with the outer shell 20 connected and forms a protection against injuries by pinching.

4 shows an embodiment in which a saddle 12 by means of saddle struts 24 and a Sattelklobens or corresponding fasteners 22 that a saddle bearing fastener 16 form, by means of a horizontal bolt 8th with a ball 48 a ball joint 44 connected is. The ball joint 44 forms the bearing element that the saddle connection element 16 with a frame connector 36 couples, which is a condyle 46 who's the ball 48 receives, as well as two fastening struts 18 includes. The fixing struts 18 are by means of a commercial Sattelklobens 23 on a saddle candle, which is adjustably held on a frame of a sports equipment 42 attached. The saddle block 23 this can be a substantially U-shaped mounting clamp 23a covering an area of the saddle candle 42 engages with a narrowed diameter, and several the mounting struts 18 form-fitting encompassing clamping elements 23b include that of a bolt 23c held together.

In the illustrated embodiment, a limiting device 80 for limiting a rotational angle of the saddle connection element 16 or the associated saddle 12 relative to the frame connector 36 around the bearing element 44 provided, which is a first limiting element 82 that with the saddle connector 16 is firmly connected, and a second limiting element 84 that with the frame connector 36 is connected or integrally formed therewith includes. The first boundary element 82 surrounds the second boundary element 84 seen in the circumferential direction about a vertical axis, wherein a predetermined distance between the two limiting elements 82 . 84 exists and only a predetermined maximum pivot angle of the saddle connection element 16 relative to that Frame connecting element 36 is possible with respect to the first axis of rotation 6 , and / or the second axis of rotation 2 and / or the third axis of rotation 4 ,

7 shows a schematic vertical sectional view of an embodiment similar 4 in which a first limiting element 82 is formed by a ring-like elastomeric element and the second limiting element 84 through the frame connector 36 itself is formed, which may be cylindrical in horizontal section. The first limiting element 82 can be arranged on an upper side four locking projections distributed over the circumference 86 have, which with corresponding recesses of a corresponding, extending substantially over the circumference holding element 88 interact. This allows the first limiting element 82 from the holding element 88 be solved by the latching projections 86 from the holding element 88 be pushed out. In this way are different first boundary elements 82 usable, which differ, for example, in terms of the size of the permitted deflection by one or more axes of rotation. Furthermore, there is the possibility that the limiting device 80 no rigid limitation of a rotation angle of the saddle connection element 16 effect, but have a damping or resilient limiting effect, so that a soft stop is achieved.

6a to 6i show sectional views of possible embodiments of the first limiting element 82 along a sectional plane VI in 7 , where different forms of a central opening 82a are realized. Due to the different cross-sectional shapes of the opening 82a result in different maximum deflection angle with respect to the second axis of rotation 2 and the third axis of rotation 4 because the first delimiter 82 depending on the direction of a deflection movement about said axes after different tilt angles with the second limiting element 84 or the frame connector 36 comes into contact. An embodiment according to 6a allows, for example, only relatively small deflections about both axes, while according to 6c larger deflections are possible. In an asymmetrical embodiment, for example according to 6d are at a deflection about the second axis of rotation 2 in a first direction only small deflections about the third axis of rotation 4 possible, while at a deflection about the second axis of rotation 2 in the opposite direction much larger deflections about the third axis of rotation 4 possible are. In an embodiment according to 6f are generally around the third axis of rotation 4 larger deflections possible than around the second axis of rotation 2 , For 6h the opposite is true. In an embodiment according to FIG. G, a deflection is in a first direction about the second axis of rotation 2 only possible to a very small extent, ie the saddle mounted on the saddle bearing device can pivot only slightly to the rear, while a forward movement is possible to a greater extent.

8th and 9 show an embodiment in which the frame connecting element 36 as a cylindrical saddle candle 42 is formed, which can be used directly in a seat tube of a bicycle frame or a corresponding receptacle of a sports equipment, while each saddle strut 24 by means of a separate tilt-adjustable clamp attachment 90 with the bearing element or the ball joint 44 connected is. The two clamps 90 , each with a saddle strut 24 interact are over a bolt 8th with a ball 48 connected in a condyle 46 is held rotatable on all sides and a ball joint or the bearing element 44 forms.

Each clamp attachment 90 comprises a first fastening part 92 that from the bolt 8th at the ball 48 is held, a second fastening part 94 that is integral with the first attachment part 92 may be formed or suitably attached thereto, a substantially semi-cylindrical third attachment part 96 that in a complementary recess of the second attachment part 94 is included, a fourth fastening part 98 , a cross-sectionally semi-cylindrical, in the fourth attachment part 98 received fifth fastening part 100 and a second, third, fourth and fifth fastening part by cross-clamping element 102 , The second attachment part 94 has a partially cylindrical jacket-shaped receiving surface 94a on, which can be provided either smooth or as shown with ratchet teeth. The third attachment part 96 has a partially cylindrical jacket-shaped bearing surface 96a on, corresponding to the receiving surface 94a is smooth or formed with ratchet teeth, so that the third attachment part 96 non-positively and / or positively from the second fastening part 94 is held. While the attachment part 94 one to the clamping element 102 , For example, has a clamping screw, matching through hole, is in the third attachment part 96 a slot-shaped opening for the passage of the clamping element 102 formed, which is a tilt adjustment of the third attachment part 96 as known from a conventional patent seat post.

The third attachment part 96 has opposite the support surface 96a a flat top 96b on, the fourth attachment part 98 at a small distance is opposite to the seat post 24 between the third and fourth fastening part 96 . 98 clamped to fix. Also the fourth attachment part 98 is with a slot-shaped passage opening for the clamping element 102 provided to a tilt adjustment of the seat post 24 to enable.

The fifth attachment part 100 could in the simplest case be a threaded nut on the fourth mounting part 98 rests, but preferably has a cylinder jacket-shaped bottom, which with a correspondingly shaped cylindrical or cylindrical shell-shaped recess of the fourth attachment part 98 interacts. The fifth attachment part 100 can be provided with internal thread, or it can be a cylindrical passage opening for the clamping element 102 have, in which case above the fifth attachment part 100 a threaded nut can be provided, which is formed with the example designed as a clamping screw clamping element 102 interacts.

In a tilt adjustment of the third and fourth fastening part 96 . 98 with saddle strut held in between 24 keep the tension element 102 and the fifth attachment part 100 their in 8th shown position, while said fasteners and the seat post can be moved forward or back in their inclination.

10 and 13 show an embodiment similar 1 , in contrast to the attachment struts 18 are not formed as a free-standing struts, which on a conventional patent seat post 43 be attached ( 1 ), but the mounting struts 18 in one piece as part of a mounting plate 19 are formed and protrude in cross-section only halbkeisförmig over the mounting plate. This has the advantage that a patent seatpost from below by sweeping fastening screw 19a directly with the mounting plate 19 can cooperate without the other fasteners of a conventional patent seat post are needed. 10 further shows a limiting device with a first bell or hemispherical limiting element 82 that with the saddle connector 16 , For example in the form of the bolt 8 held by the fasteners 22 , is firmly connected, and a second limiting element 84 on the frame connector 36 or the mounting plate 19 is appropriate. Between the boundary elements 82 . 84 As described above, there is a circumferential distance, which is a limited deflection of the saddle connection element 16 relative to the frame connector 36 allows.

11 and 12 show two different second frame connectors 84.1 . 84.2 which can be used singly or additively to achieve different limiting effects. If only a smaller second boundary element 84.1 on the frame connector 36 is placed, for example by means of a radial opening and a conical inner surface 85 , there is a relatively large distance to the first limiting element 82 and a relatively large swivel range. When placing a second boundary element 84.2 on the boundary element 84.1 , or replacement of the limiting elements, the said distance is reduced, so that the possible pivoting angle range of the saddle connection element and thus of the saddle is reduced. A Velcro tape 82b facilitates a fixation of a limiting element to the frame connecting element.

14 shows an embodiment in which a saddle 12 over the saddle struts 24 on a saddle connector 16 held, that is a bolt 8th and fasteners 22 includes.

At a distance below the upper support plate 110 is a lower support plate 120 fixed or, as shown in the illustrated embodiment, height adjustable on the saddle candle 42 held. An adjusting nut 125 with an external thread of the saddle candle 42 cooperates, allows a positional adjustment of the lower support plate 120 in terms of their distance from the upper support plate 110 , On one to the upper support plate 110 facing top of the lower support plate 120 is also a pivot bearing 130 with respect to a longitudinal axis of the saddle candle 42 that with the second, in use vertical axis of rotation 2 of the ball joint 44 coincides, rotatable bearing ring 135 arranged. Between the bearing ring 135 and the upper support plate 110 are in the circumferential direction with respect to the second axis of rotation 2 distributed and parallel to this a number of compression springs 140 arranged. In particular, the compression springs 140 , which form a return element, along the circumference of a cylindrical surface whose axis is the vertical axis of rotation in use 2 is arranged, distributed. The compression springs 140 , which form a return element can be replaced by elastomer springs or elastomeric elements, in particular by a single ring or toroidal Elastomer element whose central axis is the axis of rotation 2 is.

The individual compression springs 140 can be the same or different. In particular, it may be provided that those compression springs which are compressed or stretched backwards during a pivotal movement of the saddle about the third, in use horizontally and transversely to the direction of rotation axis, are formed stronger than those in a pivoting movement about the second, horizontal and in the direction of travel facing axis of rotation are deformed, so that a tilting movement of the saddle is counteracted reinforced toward the rear.

By an adjusting movement of the adjusting nut 125 in which the mutual distance of the support plates 110 . 120 is reduced in size, the restoring force of the return element can be increased overall, and vice versa.

15 shows a similar embodiment as 14 , first with the difference that instead of a saddle candle as a frame connecting element 36 a mounting plate 19 is provided with thereto arranged fastening struts or elements 18, with which the attachment of the saddle bearing device to a patent seat post 43 possible, analog 10 ,

Furthermore, between the saddle connection element 16 and the frame connector 36 a spring device 150 arranged, which has a spring-loaded linear motion between saddle connector 16 and frame connector 36 along a vertical axis of movement in use, which in this case is identical to the second axis of rotation 2 is, allows, along a direction of movement 160 , The spring device 150 includes a first cylindrical pipe section 162 that with the condyle 46 of the bearing element 44 is connected, and a the first pipe section 162 concentrically enclosing second pipe section 164 that with the frame connector 36 is connected or makes this. If necessary, can be placed between the pipe sections 162 . 164 another spring element 166 be arranged to the spring character of the spring device 150 to influence.

In particular, the Shore hardness (A, B, C or D) is relevant as a reference for setting the hardness parameter. In the illustrated embodiment, the different Elstomerelemente 174a . 174b and 174c different hardnesses. Even so it is possible the resistance or the restoring force of the return element 32 separately set against a deflection of the saddle from the rest position in different directions.

In the 16 and 19 to 21 In addition, further embodiments of the ball bearing are shown. In 16 For example, an embodiment is shown in which the ball 48 cohesively or even in one piece with the bolt 8th is trained. In 19 is the ball 48 of the ball joint 44 compared to the previously illustrated embodiments offset by 90 ° to the saddle struts 24 arranged. Ie. the bolt 8th that by the ball 48 leads, runs parallel to the saddle struts 24 and is over a rack 180 connected with these. Also in this embodiment ball and bolt can be configured in one piece.

The 20a and 20b represent an embodiment with "inverted" ball joint. In this case, the ball 48 on the frame connector 36 arranged and the condyle 46 is in connection with the connecting elements 22 that the saddle struts 24 hold. In 21 In addition, an embodiment is shown in which the bolt 8th not by the ball 48 is arranged, but above the ball 48 runs and at the top of the ball 48 connected to this.
