Description

    BACKGROUND OF THE INVENTION
  • The present invention is related to an ascending/descending guiding structure of a support arm of a display, which is made at low cost and enables the panel of the display to be smoothly adjusted in height. In addition, when adjusting the height of the panel, the surface of the support arm will not be worn.
  • FIG. 1 shows a conventional telescopic support arm 6 of a display. The support arm 6 is composed of two opposite metal main support racks 61 and a metal slide member 62. The main support racks 61 have opposite channels 613. Two lateral sides of one end of the slide member 62 are inlaid in the channels 613. A panel bracket 622 is connected with a top end of the slide member 62. The bottom end of the slide member 62 is connected with a slide block 623. Multiple ball bodies are disposed on the lateral sides of the slide block 623 to roll along the channels 613. The lateral sides of the slide block 623 are guided by the walls of the channels 613, whereby the slide block 623 and the slide member 62 can telescopically slide between the main support racks 61 along the channels 613. Two coiled torque leaf springs 63 are connected between the top ends of the main support racks 61 and the bottom end of the slide member 62. An adjustment bolt 6141 is disposed on the main support rack 61 for pressing a frictional block 64 against the slide member 62. The resilient force of the unwound torque leaf springs 63 can offset the weight of the panel. The frictional force exerted onto the slide member 62 by the frictional block 64 is changeable in cooperation with the resilient force of the torque leaf springs 63. Accordingly, the panel of the display can be adjusted to a desired height. The metal material is expensive. Therefore, the metallic slide member 62 and main support racks 61 of the telescopic support arm 6 are made at high cost. Moreover, these components are quite heavy and relatively uneasy to transfer.
    • SUMMARY OF THE INVENTION
  • It is therefore a primary object of the present invention to provide an ascending/descending guiding structure of a support arm of a display, which is made at low cost and enables the panel of the display to be smoothly adjusted in height at low frictional resistance. In addition, when adjusting the height of the panel, the surface of the support arm will not be worn.
  • It is a further object of the present invention to provide the above ascending/descending guiding structure of the support arm of the display, in which the slide member and the slide member are made from lubricant plastic material instead of the metal material without affecting the strength. Therefore, the cost for the material is lowered.
  • According to the above objects, the ascending/descending guiding structure of the present invention includes a sleeve and a slide member. The sleeve defines a receiving space in which the slide member is slidably received. An inner face of a wall of the receiving space is formed with multiple longitudinally extending channels or ribs. An outer face of the slide member is formed with longitudinally extending ribs or channels in cooperation with the channels or ribs of the receiving space of the sleeve. The ribs are inlaid in the channels and guided by the channels, whereby the slide member can be smoothly stably extended out of the sleeve or retracted into the sleeve at low frictional resistance.
  • The present invention can be best understood through the following description and accompanying drawings wherein:

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Please refer to FIG. 2. The ascending/descending guiding structure of the support arm of the display of the present invention includes a sleeve 1, a slide member 2 and a jacket 3. One end of the sleeve 1 defines a receiving space 10. The inner face of the wall of the receiving space 10 is formed with multiple longitudinally extending channels 12 and at least one main groove 13. The outer face of a first end of the sleeve 1 is formed with multiple outer ribs 16. A second end of the sleeve 1 is formed with multiple resilient latch plates 11 each having a hook section 111. The second end of the sleeve 1 is inserted into a dent 41 of a base 4. The bottom of the dent 41 is formed with multiple latch slots 42. The hook sections 111 of the resilient latch plates 11 are latched in the latch slots 42 to locate the sleeve 1 on the base 4. The slide member 2 has multiple longitudinally extending slats and multiple transverse reinforcing slats 24 connected between the longitudinal slats. Accordingly, the slide member 2 has a lightweight and strengthened beehive structure to save material. A first end of the slide member 2 is formed with multiple locating thread holes 21. A panel bracket 5 is formed with multiple locating holes 51. Bolts 52 are passed through the locating holes 51 of the panel bracket 5 and screwed into the locating thread holes 21 to lock the panel bracket 5 with the slide member 2. A second end of the slide member 2 is formed with multiple notches 25. Two ends of at least one shaft 141 are inserted in the notches 25. A coiled torque leaf spring 14 is fitted around the shaft 141. Two lateral sides of the slide member 2 are formed with longitudinal ribs 22. In addition, at least one projecting block 23 is disposed on outer face of the slide member 2. The longitudinal ribs 22 and the projecting block 23 respectively correspond to the channels 12 and the main groove 13 of the sleeve 1. A front side of the projecting block 23 is formed with a guide slope 231. The jacket 3 is composed of two casings 31, 32 respectively having tenons 311 and mortises 321. The tenons 311 are inserted in the mortises 321 to mate the casings 31, 32 with each other. In addition, the middles of the top ends of the casings 31, 32 are respectively formed with two opposite recesses 312, 322. After mated with each other, the recesses 312, 322 together form a slot at the center of the top end of the jacket 3.
  • FIG. 4 is an assembled view of the present invention. Also referring to FIGS. 5 to 7, when assembled, the second end of the slide member 2 extends into the receiving space of the sleeve 1. The ribs 22 (or channels) are inlaid in the channels 12 (or the ribs). The projecting block 23 is inlaid in the main groove 13. The guide slope 231 serves to guide the projecting block 23 into the main groove 13. In addition, a damper 131 is disposed in the main groove 13 near the first end of the sleeve 1. The walls of the channels 12 serve to guide the ribs 22 to move along the channels 12, whereby the slide member 2 can extend out of the receiving space or retract into the receiving space. The slide member 2 is stably fitted in the sleeve 1 at low frictional contact without swinging.
  • An outer end of the torque leaf spring 14 is formed with a hook section 143 for hooking an edge of the opening the upper end of the receiving space of the sleeve 1. Accordingly, the torque leaf spring 14 is interconnected between the sleeve 1 and the slide member 2. The resilient force of the unwound torque leaf spring 14 serves to balance the weight of the display and other components. By means of an adjustment bolt 132, the normal pressure applied by the damper 131 to the outer face of the slide member 2 is adjustable. Therefore, the resistance against the slide member 2 when sliding within the sleeve 1 is changeable in cooperation with the resilient force of the torque leaf spring 14. Accordingly, the panel of the display can be adjusted to a desired height.
  • The locating bolts 52 are passed through the slot together formed by the recesses 312, 322 and screwed into the locating thread holes 21 of the slide member 2, whereby the top end of the jacket 3 is clamped between the panel bracket 5 and the first end of slide member 2. The jacket 3 holds the slide member 2 and has such a length that when the jacket 3 is ascended along with the slide member 2 to an upper dead end, the jacket 3 can still at least shade an adjoining section between the sleeve 1 and the slide member 2. The outer ribs 16 of the sleeve 1 serve to abut against inner face of the jacket 3 so as to prevent the jacket 3 from abrading and wearing the outer face of the sleeve 3.
  • The ribs 22 serve to reduce the frictional force between the sleeve 1 and the slide member 2. Also, the sleeve 1 and the slide member 2 can be made from lubricant plastic material so as to further reduce the frictional resistance. Alternatively, the jacket 3 can be an integrated body to achieve the same effect.
  • The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
