Description

Height adjustment structure of the armrest

The present invention relates to a height adjustment structure of an armrest, which mainly comprises a sliding sleeve with a rail attached to the outside of the fixing seat, and a pulling rod which is clamped to the inner card slot of the fixing seat via the sliding seat and the clamping block, and the top end of the pulling rod extends the driving plate to protrude In the operation window of the sliding sleeve, the fixing fixing plate is covered with the top of the sliding seat and the sliding sleeve, and the bottom end of the fixing seat and the top surface of the fixing plate are respectively combined with the armrest bracket and the armrest seat to form an armrest, which can be driven. The plate drive causes the clamping block at the bottom end of the drawbar to produce a retracted, convex horizontal displacement operation to disengage or snap into the card slot of different height positions of the fixed seat, thereby providing a stable armrest height adjustment function.

Based on ergonomic design requirements, the current seat has been heavily designed with a height-adjusting armrest structure to provide the most comfortable arm rest for users of different sizes and needs.

However, the conventional armrest height adjustment structure is mostly such that the one-clip block is simply disposed with a spring and passively reciprocates along the ascending adjustment. Therefore, the armrest seat can only be gradually adjusted up to the top after the lifting adjustment, and the armrest must be The seat is pressed down to the bottom end (the clamp block will enter a dead point when it is at the topmost position of the armrest seat, and can be disengaged when the armrest seat is pressed down to the bottom end, causing the lift adjustment of the armrest seat to have a one-way loop restriction. ), it is extremely inconvenient to start the lifting adjustment of the armrest seat again. The other part of the armrest height adjustment structure is in appearance. A driving button is displayed on the outer side of the armrest, so that when the user pushes up, the internal latching structure is disengaged from the positioning slot, and the operation of freely changing the height is generated, and the latching structure is re-engaged in the vicinity after the driving button is released. In the position of the card slot, the purpose of quickly adjusting the height is achieved. However, since the linkage between the driving button and the cassette structure is mostly an oscillating operation (the driving button is oscillated in linkage with the cassette structure, or the cassette structure provides the clamping force in a swinging manner, the depth of the cassette is easily limited by the swing angle. There are insufficient problems), so it is extremely unstable in operation and is prone to jamming or unsmoothness.

In view of the above-mentioned shortcomings, the creator deeply understands that the height adjustment structure of the conventional handrail does not meet the user's convenience requirements in operation. Therefore, he has been engaged in research and development and manufacturing experience for many years, and actively carries out improvement, and carefully considers the conditions of all parties. Next, we finally created the composition of this structure, which will completely solve the problems of the application.

The present invention relates to a height adjustment structure of an armrest, which is mainly for connecting the slide rail and the sliding sleeve to the inner and outer portions of the fixed seat, and the sliding seat and the top end of the sliding sleeve are covered by the fixing plate to be combined for the armrest seat. The bottom end of the fixed seat is coupled to the armrest bracket, wherein the sliding seat accommodates a pull rod, and the top end of the pull rod extends from the operating window of the sliding sleeve, and the horizontal displacement of the clamping block can be pulled to disengage or snap into the fixing seat. In the different height and low position of the card slot, the following benefits will be provided after implementation: since the height adjustment structure of the creation armrest is driven by the upper and lower sliding of the lever in the sliding seat, the card block is retracted and convex. The horizontal displacement operation is used to disengage or snap into the card slot of different height positions of the fixed seat, thereby forming the function of adjusting the height of the armrest seat relative to the fixed seat (armrest bracket). Therefore, the user can immediately raise and lower the armrest seat according to his needs. In order to solve the problem, the handrail seat can only be limited according to the one-way cycle of the specific operation direction.

The height adjustment of the creation is generated by the retracting and convex horizontal displacement operation of the cassette block, and is relatively separated from or stuck into the card slot of different height positions of the fixed seat, so the operation process of the cassette block is extremely stable (click The block can be protruded into the card slot with sufficient length to avoid the problem of operation failure or jamming.

In order to enable your reviewers to clearly understand the structure of the creation and the functional benefits that can be achieved, the rest will be accompanied by a diagram to illustrate the examples. The details are as follows: This creation is a kind of height adjustment structure of the handrail, mainly including The slide rail 3 and the sliding sleeve 1 which are connected to the inside and outside of the fixed seat 2 (as shown in the first figure), the sliding seat 3 and the top end of the sliding sleeve 1 are combined by the fixing plate 5 to be combined for the armrest seat 7 to be combined. The bottom end of the fixing base 2 is coupled to the armrest bracket 8 so that a pull rod 4 is received in the sliding seat 3. The top end of the pulling rod 4 extends from the operating window 11 of the sliding sleeve 1 to pull the locking block 6 The horizontal displacement is to disengage or snap into the slot 23 of the different height position of the fixing base 2, wherein: the fixing base 2: a rod seat provided with the notch 21, and a closed rail groove 22 on both sides of the notch 21, and A plurality of card slots 23 are provided on one side of the notch 21 (as shown in the second figure).

Sliding seat 3: a frame cover 31 of the rail receiving recess 21 (shown in the third figure), the frame cover 31 corresponding to the operation window 11 is provided with a window 36, and a rib corresponding to the rail groove is protruded below the frame cover 31 Sheet 32 (Because the rail groove 22 is a concave closed structure (not openly extended), the rib 32 prevents the slider 3 from slipping out of the holder 2) when the slider 3 slides in the recess 21, the frame cover A notch 33 corresponding to the card slot 23 is recessed under one side surface of the 31, and a long through hole 34 is formed in the surface of the adjacent frame cover 31 along the height of the notch 33, and an abutment seat 35 is protruded inside the frame cover 31.

The tie rod 4 is a flat rod that is accommodated in the slide base 3 and can be slid up and down. The top end of the pull rod 4 extends from the operation window 11 of the sliding sleeve 1 via the window 36, and a bottom end is hollowed out at the middle of the rod surface. The opening 44 of the spring seat 43 is disposed, and an inclined hole 42 is disposed below the face of the face, so that the upper and lower ends of the inclined hole 42 can maintain the left and right ends of the corresponding long through hole 34 in the upper and lower sliding strokes of the pull rod 4.

The latching block 6 is a block that can be inserted into the slot 23 by being placed on the notch 33, and the extending shaft 61 is inserted into the long through hole 34 via the inclined hole 42 on the side of the block.

With the above-mentioned members, the pull rod 4 is received in the sliding seat 3, and the abutting seat 35 is protruded through the opening 44 of the pull rod 4, and is placed on the abutting seat 35 and the spring seat 43 by a spring 45. In this case, the normal state of the tie rod 4 is kept downward, so that the shaft body 61 of the click block 6 is restricted by the inclined hole 42 and the long through hole 34, and is normally protruded through the notch 33 to be stuck into the card slot 22. Therefore, when the latching block 6 is pushed into the retraction, the slider 3 can be directly inserted into the recess 21 of the fixing base 2, so that the fixing plate 5 is coupled to the top end of the slider 3 (the type of the fixing plate 5) The type is not limited, and can be combined with the sliding seat 3 and the sliding sleeve 1 and then combined with the armrest seat 7), and the fixing seat 2 is inserted into the sliding sleeve 1 (because the driving plate 41 protrudes from the window 36, it is required at this time) The push-in driving plate 41 is elastically deformed to fit into the sliding sleeve 1 and is retracted by the elastic force of the driving plate 41 to be convex at the operating window 11. At this time, the exposed end of the driving plate 41 can be sleeved with a driving button 411. In order to facilitate the user's operation, the fixed plate 5 is covered with the top end of the sliding sleeve 1 and the armrest base 7 is combined, and the armrest bracket 8 can be combined with the armrest bracket 8 at the bottom end of the fixing base 2.

Therefore, when the creation is performed, the driving plate 41 can be pushed up to slide the lever 4 upward in the sliding seat 3 (as shown in the fourth figure, the spring seat 43 slides against the seat 35 to compress the spring 45). The upward sliding of the pull rod 4 drives the inclined hole 42 to pull the shaft body 61 back to the inner side along the long through hole 34, so that the click block 6 is retracted from the slot 23 and loses the latching effect, and the armrest seat 7 is freely opposed to the fixed seat 2. Height lifting adjustment (the armrest seat 7, the fixed plate 5, the sliding sleeve 1, the pull rod 4 and the sliding seat 3 are slid and lifted together with respect to the fixed seat 2), and the lever 4 is reset (down pushed) by the spring 45 on the release driving plate 41 When the inclined hole 42 reversely pushes the shaft body 61 along the outer side of the long through hole 34 (as shown in FIG. 5), the click block 6 keeps the card jam into the card slot 23 via the notch 33, so the card The cymbal block 6 can be protruded into the opposite one of the card slots 23 according to the adjustment direction of the armrest base 7, thereby completing the purpose of the cymbal fixing.

According to the structural design of the above-mentioned creation, since the shaft body 61 of the latching block 6 is horizontally displaced in the long through hole 34 of the slide base 3 by the inclined hole 42 of the pull rod 4, the cassette is moved. The locking action of the block 6 and the convex portion relative to the slot 23 is extremely stable, and the protruding length can be sufficiently deep into the card slot 23, so that not only the operation failure or the jamming problem but also the armrest 10 can be extremely Good support.
