Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are referred to only in the direction of the attached drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.
According to an embodiment of the present invention, a height adjustment structure for a foot rest is provided, which can be disposed on a bottom surface of a keyboard to adjust an inclination angle of the keyboard. Because the traditional wrenching foot rest has only one supporting state, the user can not have the opportunity to adjust the height, and in order to enable the foot rest of the keyboard to have multiple supporting states, the embodiment provides the foot rest capable of being adjusted in a segmented mode, so that the inclination angle of the keyboard has more choices, and the operation habit of the user is met. Of course, the height adjustment structure of the foot rest of the present embodiment can also be used in other structures, such as height-adjustable desks, game tables, etc., and the present invention is not limited thereto.
Referring to fig. 1A and 1B, the foot stand height adjusting structure 100 may include a movable body 110, a height adjusting member 120, a height maintaining member 130, a first elastic member 140, a second elastic member 145, and an elastic retaining member 150.
The movable body 110 is, for example, a cylinder, and is disposed in the sleeve 131 (i.e., the height maintaining member 130) of the housing 101. The movable body 110 can be hidden in the housing 101 or protrude out of the housing 101 to serve as a stand for supporting the housing 101. In one embodiment, the outer surface (bottom surface) 103 (shown in fig. 2A) of the housing 101 has an opening 104, for example, and the movable body 110 can protrude out of the housing 101 or be hidden in the housing 101 through the opening 104. It should be noted that the casing 101 may be a separate component of the foot rest height adjusting structure 100, or may be an outer casing of a keyboard (or a desk or a game table) on which the foot rest height adjusting structure of the present invention is installed.
The height adjustment member 120 is, for example, a rod, and is disposed on the movable body 110. In an embodiment, the height adjusting element 120 and the movable body 110 may be accommodated in the sleeve 131, and then inserted and fixed on the movable body 110 by a fastening or locking manner, and one end of the height adjusting element 120 may extend out of the sleeve 131 and be connected to the second elastic element 145, as shown in fig. 2A. The height adjuster 120 may be moved to the first height position P1, the second height position P2, or the third height position P3 by adjusting the height of the movable body 110. As shown in fig. 2A, the height adjuster 120 is located at a first height position P1. As shown in fig. 2B, the height adjuster 120 is located at a second height position P2. As shown in fig. 2C, the height adjuster 120 is located between the second height position P2 and the third height position P3. As shown in fig. 2D, the height adjuster 120 is located at a third height position P3. It should be noted that, regarding the adjustment of the height of the movable body 110, the height adjustment is performed by rotating the movable body 110 in the present embodiment.
The height maintaining member 130 is, for example, a sleeve 131, which is disposed on the inner surface 102 of the housing 101. The sleeve 131 covers around the opening 104 of the housing 101, and an inner diameter of the sleeve 131 is slightly larger than an outer diameter of the movable body 110, so that the movable body 110 accommodated in the sleeve 131 has only a freedom degree of movement along a vertical axis Z (i.e., a height adjustment direction). As shown in fig. 2A, the height maintaining member 130 has a non-linear continuous groove L1 for guiding the height adjusting member 120 to a predetermined height, so that the height adjusting member 120 stops at a predetermined height position. In one embodiment, the height adjusting member 120 may be received in the non-linear continuous groove L1 and moved to a predetermined height position according to the shape of the groove L1, so as to adjust the height of the stand in stages.
In addition, the first elastic member 140 is, for example, a tension spring, and abuts against the movable body 110 in the vertical axial direction Z. One end 141 of the first elastic member 140 is fixed and the other end 142 is movable. Therefore, when the movable body 110 is hidden in the housing 101, the first elastic member 140 is compressed to store an elastic force, and when the movable body 110 is to protrude out of the housing 101, the first elastic member 140 can release the elastic force to provide a pushing force for the movable body 110 to move toward the opening 104. That is, when the height of the movable body 110 is adjusted, the first elastic member 140 cooperates with the height adjustment of the movable body to move the height adjustment member to the second height position or the third height position.
In addition, the second elastic member 145 is, for example, a compression spring, which connects the height adjusting member 120 in the horizontal axis direction X (perpendicular to the height adjusting direction). In one embodiment, one end 146 of the second elastic member 145 is fixed and the other end 147 is movable. Therefore, the second elastic member 145 can be stretched to store an elastic force as the height adjustment member 120 rotates, and can provide a pulling force when the height adjustment member 120 rotates reversely by releasing the elastic force. In one embodiment, one end 146 of the second elastic member 145 is fixed on a rod 148 or movably sleeved on the rod 148. When the height of the height adjustment member 120 is changed, one end 146 of the second elastic member 145 may be fixedly held at a predetermined height position or may be moved to other height positions along with the height adjustment member 120. The rod 148 is disposed on the inner surface 102 of the casing 101.
Furthermore, the elastic holder 150 includes, for example, a locking member 151 and a third elastic member 152, which are disposed on the inner surface 102 of the housing 101 for locking the movable body 110. In addition, the releasing member 155 is disposed on the outer surface 103 of the housing 101 and connected to the elastic retaining member 150 for releasing the locking member 151, so that the locking member 151 is separated from the movable body 110. The third elastic member 152 is, for example, a tension spring, and abuts against the locking member 151 in the other horizontal axial direction Y (perpendicular to the height adjustment direction). One end 153 of the third elastic member 152 is fixed and the other end 154 is movable. In a normal state, the third elastic element 152 can make the locking element 151 continuously locked on the movable body 110.
As shown in fig. 2A, the latch 151 may be inserted into the movable body 110 through the sleeve 131, so that the latch 151 is engaged with the movable body 110, and the movable body 110 is fixed at the first height position P1. If the height of the stand needs to be adjusted, the user only needs to pull the releasing member 155 to separate the locking member 151 from the movable body 110.
Referring to fig. 2B, the first elastic member 140 can move the height adjustment member 120 from the first height position P1 to the second height position P2. The first height position P1 and the second height position P2 are located at two ends of a straight line L11 of the trench L1, for example. The straight line segment L11 is a straight slot and the straight line segment L11 extends along the vertical axis Z. Therefore, the movable body 110 can be driven by the first elastic member 140 to move downward.
Referring to fig. 2C and fig. 2D, the second height position P2 and the third height position P3 are located at two ends of the nonlinear segment L12, wherein the nonlinear segment L12 is a U-shaped groove, and the U-shaped groove has a turning region T (shown in fig. 2A). The height adjustment member 120 can move along the groove L1 from the second height position P2 to the transition region T, and then move along the groove L1 from the transition region T to the third height position P3. In fig. 2C, when the height adjustment member 120 moves from the second height position P2 to the transition region T along with the rotation of the movable body 110, the second elastic member 145 is stretched, and the first elastic member 140 provides the pushing force for the movable body 110 to move toward the opening 104 again, so that the height adjustment member 120 moves downward and passes through the transition region T. In fig. 2D, the height adjustment member 120 moves along the groove L1 from the transition region T to the third height position P3 under the pulling force provided by the second elastic member 145.
In addition, as shown in fig. 2D, when the movable body 110 moves to the third height position P3, the latch 151 may pass through the sleeve 131 and be inserted into the movable body 110, so that the latch 151 and the movable body 110 are engaged with each other, and the movable body 110 is fixed at the third height position P3.
As can be seen from the above description, the non-linear continuous groove L1 includes a linear segment L11 and a non-linear segment L12 connected to each other, the height adjustment member 120 can move to a predetermined height position according to the shape of the groove L1, and the first elastic member 140 can cooperate with the rotation of the movable body 110 to move the height adjustment member 120 from the first height position P1 to the second height position P2 or the third height position P3. In addition, when the height adjustment member 120 moves to the second height position P2 or the third height position P3, the second elastic member 145 can apply a pulling force to the height adjustment member 120. In addition, when the height adjuster 120 moves to the first height position P1, the second height position P2, or the third height position P3, the elastic holder 150 is engaged with the movable body 110, or the third elastic member 152 is released by the release member 155, so that the elastic holder 150 is separated from the movable body 110. Furthermore, by rotating the movable body 110 in the reverse order, the height adjustment member 120 can be moved from the third height position P3 to the first height position P1 or the second height position P2 in stages, so as to achieve the purpose of adjusting the height of the stand in stages.
It should be noted that, in the present embodiment, the second elastic member 145 and the elastic holder 150 are not essential components, and may be omitted.
