{Tilting Devicd Head Board For Bed}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head board tilting apparatus, and more particularly, to a head board tilting apparatus capable of tilting a headboard of a bed at a predetermined angle by using a tilting apparatus capable of multi- And to do so.

Generally, a bed is provided by placing a mattress on a horizontal top plate, and a head plate is provided on one side and used only for sleeping, and a head plate projecting upward is uniformly fixed.

Therefore, when you want to lean your back on the headboard at a comfortable angle, or watch television or read books, you can use a separate bedding such as a pillow or a backrest cushion to support the waist or shoulders. There is no problem.

In addition, there is a medical bed in which a mattress is bisected and a tilt of a portion of the upper metric portion that the upper body of the human body touches can be adjusted. However, since the structure for obtaining a desired angle by rotating the rotation axis of the tilting device several times is inconvenient , The mattress cover (mattress cover) surrounding the mattress is washed down by the weight, and the service life is shortened by the bending structure of the mattress.

9 is a side view showing a state where the tilted state is one step at a predetermined angle ? 1, FIG. 10 is a side view showing a state where a predetermined angle? and the side of the (θ 2) to the two-stage tilting state, Figure 11 is a predetermined angle (θ 3) to a side surface prior to the 3-tilting, Figure 12 is a predetermined angle (θ 4) in a side of the tilting state 3- 18 is a side view of the bed in a state where the headboard 77 is tilted at a small angle ? 7 and FIG. 19 is a side view of the bed in a state where the headboard 77 is tilted at a large angle ? 8.

The tilting process according to the present invention will now be described with reference to FIGS. 8, 14, 15, 16 and 17, in which the user does not tilt the headboard 77, The rotary plates 45 and 46 connected to the support portion 3 are rotated in the counterclockwise direction about the shaft rod 37 by a predetermined interval and the click portions 61 and 62 are rotated in the counter- And the other side of the engaging pieces 33 and 34 supported on one side of the space portions 18 and 22 is rotated in the counterclockwise direction along the rotary plates 45 and 46 by a click 62a. When the force for lifting the head plate 77 is removed in this state, the head plate (not shown) acting downward around the shaft rod 37 by the weight of 77) clamping members 33, 34. the first stage of a predetermined tilting angle (θ 1) being achieved the other side as shown in Fig. 9 as the click engagement (61a) (62a) of , Spring 23, 24 is one-stage tilting by the elastic force remain constant because of the user leaning against the headboard 77 is in a comfortable position for watching TV, or it is possible to the reading light.

If the user desires to tilt in two steps, the user can lift the headboard 77 at a proper angle while holding the lower end or the side surface of the headboard 77, and the rotary plate 45 (46) The click portions 61 and 62 are also rotated in the counterclockwise direction along the rotating plates 45 and 46 by a predetermined interval and are rotated by a predetermined distance in the space portions 18 and 22, When the other side of the retaining members 33 and 34 is clicked into the clicks 61b and 62b, the entering state is supported by the biasing force of the springs 23 and 24. In this state, The other side of the engaging pieces 33 and 34 is caught by the clicks 61b and 62b by the weight of the head plate 77 acting downward about the shaft rod 37, Likewise, the two-step tilting of the predetermined angle ? 1 is achieved, and the tilting of the second tilting is continuously maintained by the elastic force of the springs 23 and 24, The user can lean against the headboard 77 in the posture to watch television or read books.

In the above case, the user can manually lift the headboard 77 to achieve the second tilting in a state where the headboard 77 is not tilted as shown in Figs. 8, 14, 15, 16, In the first tilting, the headboard 77 can be lifted a little further to achieve the second tilting.

When the user desires to tilt in three steps, the user rotates the shaft 37 by the rotation plate 45 (46) connected to the support part 3 by lifting the lower end or the side of the headboard 77 with the hand at an appropriate angle The click portions 61 and 62 are also rotated in the counterclockwise direction along the rotating plates 45 and 46 by a predetermined interval and are rotated by a predetermined distance in the space portions 18 and 22, When the other side of the retaining members 33 and 34 is clicked into the clicks 61c and 62c, the entering state is supported by the resilience of the springs 23 and 24. In this state, The other side of the engaging pieces 33 and 34 is caught by the clicks 61c and 62c by the weight of the head plate 77 acting downward about the shaft rod 37, Likewise, the three-tilting of the predetermined angle ? 4 is achieved, and the three-tilting is continuously maintained by the elastic force of the springs 23 and 24, The user can lean against the headboard 77 in the posture to watch television or read books.

In such a case, as shown in FIGS. 8, 14, 15, 16, and 17, in a state in which the headboard 77 is not tilted, the user can raise the headboard 77 by hand to immediately achieve three- In the first tilting or second tilting state, the headboard 77 can be lifted a little further to achieve the third tilting.

On the other hand, when the tilting state is to be released, the head plate 77 in the first tilting state, the second tilting state or the third tilting state is further lifted as shown in Fig. 13, The other end of the engaging pieces 33 and 34 which have been resiliently biased by the springs 23 and 24 further moves in the direction of the shaft rod 37 so that the engaging grooves 16 and 20 of the spring chambers 13 and 14 And contact with the ends of the clicks 61a, 61b, 61c, 62a, 62b, 62c is prevented.

That is, the end portions of the clicks 61a, 61b, 61c, 62a, 62b, 62c are spaced apart from the outer virtual circle K of the engaging pieces 33, 34, The tilting and the engagement are released and when the force of lifting the headboard 77 in this state is removed, the weight of the headboard 77, which acts downward about the shaft rod 37, (Or nearly vertical) while rotating clockwise around the shaft rod 37 as shown in FIGS. 15, 16, 17, and 17, and the end portions of the click portions 61 The engaging pieces 33 and 34 engaged in the engaging grooves 16 and 20 by the pressing of the inclined portions 57 and 58 located on the side of the shaft rod 37 due to the biasing force of the springs 23 and 24, The tilting can be released to the original position where the tilting can be stopped by the clicks 61a, 61b, 61c, 62a, 62b and 62c, (77) is fixed The government material 76 to be able to make the next tilting while stopped by the buffer member (79).

Has been described, separated by convenience headboard 77, a tilting stage the first stage, second stage, third stage of the described in the present invention, and the course may be longer than the three-stage, a predetermined angle (θ 1) (θ 2) (θ 3) ( θ 4) ( θ 6) ( θ 7) ( θ 8) is set to any angle convenient to use.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
