Description
- The present application is based on, and claims priority from, Taiwan Application Serial Number 94102375, filed Jan. 26, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety.
- 1. Field of the Invention
- The invention relates to a height adjusting apparatus and, in particular, to a stepless height adjusting apparatus.
- 2. Related Art
- As shown in
FIG. 1 , a conventional height adjusting device of a thin display apparatus is comprised of aslider 100′, aslide way 200′, acoil spring 300′ and abase 500′. The thin display apparatus is installed on acoupling portion 120′ of theslider 100′. A user imposes a force on the thin display apparatus to adjust the height of the thin display apparatus. After the force is removed, a weight of the thin display apparatus and theslider 100′ is equal to a sum of an elastic force of thecoil spring 300′ and a friction between theslider 100′ and asliding sleeve 210′ on theslide way 200′. Therefore, theslider 100′ can stop at any position on theslide way 200′. The weight of the thin display apparatus is invariant. However, the friction between theslider 100′ and thesliding sleeve 210′ on theslide way 200′ and the elastic force of thecoil spring 300′ vary with time, adjusting frequency, temperature, and climate. Once thecoil spring 300′ is subject to elastic fatigue, or the friction between theslider 100′ and thesliding sleeve 210′ changes, it is difficult to achieve a balance of the forces to maintain the height of the thin display apparatus. Moreover, a replacement of thecoil spring 300′ is time-consuming and inconvenient. - An object of the invention is to provide a stepless height adjusting apparatus that uses an elastic supporting device in place of a coil spring to achieve a stepless height adjustment.
- Another object of the invention is to provide a stepless height adjusting apparatus that can used for all kinds of devices with different weights to adjust the height of the devices by simply adjusting the angle and/or elastic force of an elastic supporting device.
- A further object of the invention is to provide a stepless height adjusting apparatus that can be readily disassembled.
- To achieve the above objects, the disclosed stepless height adjusting apparatus includes a slider, a slide way, and an elastic supporting device. The slider is an axially symmetric bar. A cross section of the bar in a top portion is larger than a cross section of the bar in a bottom portion so as to form an incline on a side surface of the slider. The cross sections are perpendicular to an axis of the slider. Therefore, the side surface inclines from the top portion to the bottom portion of the slider. The slider couples to the slide way to move on the slide way. The elastic supporting device is disposed on the top portion of the slide way to support the slider by a way of a balanced force between the elastic supporting device and the incline of the slider. The elastic supporting device includes two fixing bases and two supporting frames. The fixing bases are disposed respectively on two sides of the top portion of the slide way. Each fixing base contains a pivotal point and an angle adjusting groove. One end of the supporting frame is coupled to the pivotal point and the supporting frame wiggles about the pivotal point. The supporting frame contains a pushing rod, a spring, and a fixing device. The pushing rod is disposed on the top portion of the supporting frame. The spring is coupled between the pushing rod and the supporting frame. The spring provides a predetermined elastic force to the pushing rod to support the slider by a front end of the pushing rod. The fixing device is disposed on the other end of the supporting frame and coupled to the angle adjusting groove. The angle between the elastic supporting device and the slider is determined by the coupling position of the fixing device and the angle adjusting groove, thereby adjusting component forces of the pushing rod in the direction along the incline of the slider and the horizontal direction.
- When an external force is pushing the slider, the slider moves along the slide way. When the external force is removed, the slider stops at a determined position by a balanced force between the elastic supporting device and the incline of the slider. Thus, the present invention achieves the object of stepless height adjustment.
- These and other features, aspects and advantages of the invention will become apparent by reference to the following description and accompanying drawings which are given by way of illustration only, and thus are not limitative of the invention, and wherein:
-
FIG. 1 is a schematic view of a conventional height adjusting apparatus; -
FIG. 2 shows a side view and a top view of the disclosed stepless height adjusting apparatus of the present invention; -
FIG. 3A is a schematic view showing the directions of gravity and friction of the height adjusting apparatus of the present invention; -
FIG. 3B is a schematic view showing balance of forces of the present invention; and -
FIG. 3C is a schematic view showing a state of a device moved by an external force. - As shown in
FIG. 2 , a disclosed stepless height adjusting apparatus includes aslider 100, aslide way 200, and an elastic supportingdevice 300. - The
slider 100 is an axially symmetric bar. A cross section of the bar in a top portion is larger than a cross section of the bar in the bottom portion so as to form an incline on a side surface of theslider 100, and the cross sections are perpendicular to an axis of the slider. The side surface of theslider 100 is thus an incline surface from the top portion to the bottom portion of theslider 100. Theslider 100 contains acoupling base 120 for coupling to a device, such as a thin display apparatus. The height of the device is adjusted by the stepless height adjusting apparatus. - The
slide way 200 is coupled to theslider 100 for moving thereon. Theslide way 200 contains asliding sleeve 210 between theslide way 200 and theslider 100 for theslider 100 to move smoothly. - The elastic supporting
device 300 is disposed on the top portion of theslide way 200 and contains twofixing bases 310 and two supportingframes 320. Thefixing bases 310 are disposed respectively on the two sides of the top portion of theslide way 200. Eachfixing base 310 contains apivotal point 311 and anangle adjusting groove 312. - One end of the supporting
frame 320 is coupled to thepivotal point 311 and the supportingframe 320 wiggles about thepivotal point 311. The supportingframe 320 contains a pushingrod 331, aspring 332, and afixing device 322. The pushingrod 331 is disposed on the top portion of the supportingframe 320. Thespring 332 is coupled between the pushingrod 331 and the supportingframe 320. Thespring 332 provides the pushingrod 331 with a predetermined elastic force, so that a front end of the pushingrod 331 supports theslider 100. The pushingrod 331 contains aroller 333 disposed on the front end of the pushingrod 331. The motion between theslider 100 and the pushingrod 331 is smooth. The fixingdevice 322 is disposed on the other end of the supportingframe 320 and coupled to theangle adjusting groove 312. The angle between the elastic supportingdevice 300 and theslider 100 is determined by the position of the fixingdevice 322 coupled to theangle adjusting groove 312, thereby adjusting the component forces of the pushingrod 331 in the direction along the incline of the slider and the horizontal direction. - The disclosed stepless height adjusting apparatus includes a base 500 coupled to the bottom of the
slide way 200 to increase a stability of the apparatus as it stands. - When an external force is applied to adjust the height of the
slider 100, theslider 100 moves along theslide way 200. When the external force is removed, theslider 100 stops at a determined position by a balanced force between the elastic supportingdevice 300 and the incline of theslide 100 to achieve stepless height adjustment. - As shown in
FIG. 3A , when adevice 900 such as a thin display apparatus is installed on thecoupling base 120, theslider 100 moves downward due to the gravity F1 of theslider 100 and thedevice 900. An upward friction F2 is generated between theslider 100 and the slidingsleeve 210 of theslide way 200 as theslider 100 moves downward. - As shown in
FIG. 3B , F2 counteracts by F1 to form a downward gravity (F1−F2). This gravity can be decomposed into a component force F3 in the direction along the incline of the slider and a component force F4 in the horizontal direction. The elastic force imposed by the spring on the pushing rod can also be decomposed into a component force F5 in the direction along the incline of theslider 100 and a component force F6 in the horizontal direction. When the component force F3 of the gravity (F1−F2) is equal to the component force F5 and the horizontal component force F4 is equal to the component force F6, a static balance is reached to stop theslider 100 and thedevice 900. - As shown in
FIG. 3C , an external force F7 is applied to move theslider 100 and thedevice 900 upward or downward. Since the external force F7 breaks the static balance, theslider 100 and thedevice 900 are moved upward or downward along theslide way 200. Once the external force F7 is removed, the forces are balanced again. Therefore, theslider 100 and thedevice 900 stop at a determined position to achieve stepless height adjustment. - In
FIG. 3C , the external force F7 is the upward external force to lift thedevice 900. However, if F7 is a downward external force, then the component force F8 of (F1−F2+F7) along the incline of the slider is greater than F5. In this case, thedevice 900 is moved downward by F7. - The above description only refers to a part of the
slider 100 and the corresponding elastic supportingdevice 300. Since the stepless height adjusting apparatus is axially symmetric, the above explanation is sufficient to understand a relation between the symmetric slider and the corresponding elastic supporting device. - To support all kinds of devices with different weights, the angle between the elastic supporting
device 300 and theslider 100 is determined by adjusting the coupling position of the fixingdevice 322 and theangle adjusting groove 312. The range of the angle is between 0 degree and 90 degrees. When the pushing rod is upward and parallel to the incline of theslider 100, the angle is 0 degree. When the pushingrod 331 pushes theslider 100 to become perpendicular to the incline of theslider 100, the angle is 90 degrees. Thereby, the component forces of the pushingrod 331 in the direction along the incline of theslider 100 and the horizontal direction can be adjusted. The smaller the angle between the elastic supportingdevice 300 and theslider 100 is, the large component force in the direction along the incline of theslider 100 is and the smaller the horizontal component force is, so that this is used for the heavy devices. On the other hand, the larger the angle between the elastic supportingdevice 300 and theslider 100 is, the smaller the component force in the direction along the incline of theslider 100 is and the larger the horizontal component force is, so that this is used for lighter devices. When the angle is 0 degree, the pushingrod 331 does not push and support theslider 100. When the angle is greater than 90 degrees, the elastic force of thespring 332 has a downward component along the incline of theslider 100, which is the same direction as the gravity of thedevice 900 and theslider 100. In this case, the gravity of thedevice 900 and theslider 100 are not balanced. Therefore, the angle between theslider 100 and the elastic supportingdevice 300 of the present invention is preferably between 0 and 90 degrees. The elastic supportingapparatus 300 can be replaced by astronger spring 332 to support heavier devices that theoriginal spring 332 cannot support. - Various kinds of modifications can be made to the disclosed embodiments without departing from the spirit of the invention. For example, the incline of the
slider 100 can be made into a curved surface, in accord with the properties of thespring 332. As long as the balanced force situation can be achieved between the elastic supportingdevice 300 and theslider 100, then different shapes of devices can be used. All such variations should be included within the scope of the invention. - From the above-mentioned embodiments, that the invention has the following advantages:
-
- 1. An elastic supporting device replaces the coil spring to achieve stepless height adjustment and solves the problems in a coil spring type of height adjusting apparatus.
- 2. 2. The angle and/or the elastic force of the elastic supporting device can be easily adjusted to support all kinds of devices with different weights.
- 3. The disclosed stepless height adjusting apparatus can be readily assembled or disassembled for the convenience of device replacement and maintenance.
- Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
