Adjustable bicycle seat tube control structure

The invention relates to a control structure, in particular to a bicycle seat tube for oil pressure and air pressure mixing application, in order to control and switch the internal oil passage circulation, so that the inner and outer tubes of the bicycle and the seat cushion height thereon can be used. Change adjusters.

The height of the bicycle seat cushion, on the one hand, is one of the elements of whether the rider can reduce the sports injury, and on the other hand, riding the bicycle in the correct posture can obtain the best and most labor-saving efficiency of the pedaling action; In line with the different needs of each person's height and the consideration of economic benefits in manufacturing, the adjustable seat tube height of the bicycle seat cushion has become the focus of research and development in the industry in recent years.

At present, the height of the adjustable seat cushion is mainly provided by a height adjusting device between the seat tube and the seat tube riser, and the relative position of the two is changed by linear displacement to achieve the height adjustment function. Such height adjustment devices can be classified into "mechanical", "gas-oil-pressure", and "hybrid" depending on the dynamic application of the actuator. Among them, "mechanical" uses certain mechanical characteristics. The action is made to adjust the relative height position between the seat tube and the seat tube riser; the "gas oil pressure type" is used to adjust the seat tube and seat by using the pneumatic member or the hydraulic member, or both. The relative height position between the risers of the mats; the "mixed type" is combined with the "mechanical" and "gas-oil-pressure" structural applications, and the actuation is used to adjust the relative height position between the seat tube and the seat riser.

Since the height adjustment device is provided with a brake group, whether it is "mechanical", "gas-oil pressure type" or "hybrid type", the switch of the height adjustment device is opened to be highly adjustable and adjusted to a predetermined height. The control switch is positioned to be closed. It can be divided into two types, "combination type" and "external type", depending on the installation location of the brake unit. It is directly mounted on the seat tube or the cushion riser, and is connected to the adjustment device to brake the person; the "external type" refers to the frame on which the brake device is mounted on the non-seat tube or the cushion riser. Any other part.

According to the prior art, the height-braking structure of the seat cushion of the "combination type" is disclosed in the U.S. Patent No. 7,083,180 B2, wherein the brake seat tube internal adjustment group produces an adjustable brake group, which is provided on the seat cushion. The position between the riser and the clamping group is to move the rotating rod 170 to push the internal valve stem 146 to actuate, and to switch between opening and closing, so that the internal oil passage of the seat riser and the seat tube is circulated or not, A state transition that can be adjusted or positioned is achieved.

There is also a "mounting type" seat cushion height brake structure, such as the "highly adjustable bicycle seat cushion riser structure" disclosed in the Japanese Patent No. 097223637, which mainly comprises an inner seat tube and an outer edge thereof. An adjustment groove is arranged in the axial direction of the predetermined portion, and the groove walls on both sides are inclined, and a plurality of adjustment holes arranged axially are arranged at the bottom edge of the adjustment groove; an outer tube is sleeved on the outer edge of the inner seat tube The inner seat tube can be displaced relative to the inner diameter of the outer tube, and a plug member is disposed on the lower end edge of the outer tube to effectively block the opening thereof, and a predetermined height extends toward the inner portion of the outer tube at the center of the outer tube a positioning rod; an elastic member is disposed in the outer tube, one end of which is disposed outside the positioning rod, and the other end abuts against the inner seat tube; an adjustment brake group is connected to each of the outer tube and the inner tube The radial direction of the seat tube is disposed in the outer tube and the adjusting groove portion, and the wire diameter is changed with respect to the adjusting groove at the same time, and the predetermined portion can be embedded in one of the adjusting holes. a positioning member, and the locating member is formed at a position opposite to the inclined wall on both sides of the adjusting groove Contact with the tapered shape, the positioning member is generated or not the embedded state switching diameter radial displacement.

The "seat-type" seat-type height-reducing structure of the "external-type" is disclosed in the "Bike's seat cushion lifting structure" disclosed in the Japanese Patent No. 094,204,651, which has a lifting device and a control device. The body and the lock solid are matched with the accommodating groove of the bicycle in the seat tube, and the lock solid body is provided with a limit block and a through hole is arranged, and a plurality of rigid sleeves, a soft sleeve, a gasket and a base are arranged The utility model is provided in combination with the seat rod of the bicycle. The base is provided with a plurality of protrusions on the peripheral wall surface and forms a plurality of joint spaces, and a washer, a screw solid body and a shaft rod are arranged to be matched, and the control device is provided with a trigger body and A rope body is coupled to a predetermined portion of the block by a lock solid, and the bicycle is provided with a closed surface in the receiving groove of the seat tube, and a through hole is provided at the upper end of the seat rod for the rope body to be worn. And a flange is formed in the middle ring and a plurality of joint blocks are protruded at the lower end to form a plurality of joint grooves.

In the above structure, the former two are all "combination type" structures. The main design concept is that the brake switch is placed on the seat tube or the seat riser. The first type can be directly connected to the internal valve stem. The connection is further controlled to produce a linear actuation, and the brake structure is more suitable for the "gas-oil pressure type" height adjustment device; the second type is provided between each of the seat tube and the seat cushion riser by using a card insertion device. The plurality of adjusting holes are arranged in the axial direction, and the state of the positioning is interrupted by the radial wire diameter displacement, and the adjusting hole is suitable for the height according to the height of each adjusting hole; the third type is The "external type" mainly consists of the control device being placed on the handlebar to facilitate hand switching, and the lifting device connected by a steel cable can be synchronously braked to generate the adjuster.

Further analysis of the "external" brake structure of the latter is based on the "mechanical" adjustment device combined with the "external" brake group; the first "combination" brake structure is matched with "gas oil pressure". "Adjustment device"; however, the "gas-oil type" height adjustment device, which is often limited to the position of the valve stem, is intended to be linearly actuated, and must be designed in a "set-up" manner. Generally, the gas-oil type valve stem is mostly extended from the seat cushion riser to the valve block, so most of them are located at the upper position of the seat cushion riser, and the brake device must be placed close to the clamp head; However, when the valve stem is designed to extend from the seat tube portion upward to the adjustment structure of the valve block, the brake device must be placed at the lower portion to facilitate connection with the valve stem and control its actuation.

The inventor of the present invention specially designed such a "gas-oil pressure type" adjusting device to be controlled by the lowering of the valve stem. In addition to the application of "combination type braking", it is considered that there is room for further improvement. Another novelty and progressive control structure for the height adjustment of the bicycle seat tube.
