INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to tilting seats and locking devices for securing tilted positions, and more particularly for general use in lightweight seats and related furniture. A locking device for a cantilever bracket type tilt mechanism. [Prior Art] It is generally required that the seat can be tilted backwards by a person at will. The tilting feature can be achieved by using various types of mechanisms including springs, mechanical shafts, and cylinders. However, the bulky and less complex tilting mechanism is a cantilever bracket. The cantilever bracket is made of a generally rigid material that flexes when a load is applied thereto. The cantilever bracket is attached to the upper portion of the seat at one end and to the lower portion of the seat at the other end, and has sufficient rigidity to seat the seat when the seat is empty or when the person sits vertically in the seat The upper part remains in an ugly position. However, when the person leans back against the upper portion of the seat, the cantilever bracket flexes, thereby allowing the upper portion of the seat to be inclined relative to the lower portion of the seat. Cantilever brackets can be used in any type of seat, but most often Φ for lightweight outdoor dining chairs. Although it is necessary to tilt the seat, it is sometimes necessary to disable the skew mechanism. For example, when a person is eating at a table, the tilted seat can be unofficial, distracting, and/or undesirable for other reasons. Therefore, it is advantageous in the seat to have the tilt locking device to be freely activated and closed by the person. Therefore, a tilting mechanism for locking the tilting mechanism of the cantilever bracket is disclosed, which prevents the seat having the cantilever bracket type tilting mechanism from tilting backward. 125743.doc 200840517 SUMMARY OF THE INVENTION [The invention includes a distal frame portion, a coupling to the base portion or the cantilever support locking position, and an unlocked position of the locking device, the downward deflection of the locking device.

In the embodiment where the lock can support the distal end of the cantilever bracket, the cantilever bracket is limited. In the embodiment, the locking device includes a body and the lock contacts the cantilever bracket and the base portion. In another aspect, the present disclosure includes a piece of furniture comprising: a base P knife, the frame 0 卩, coupled to the base portion such that the frame: the base is inclined relative to the base portion; and a locking device having a locked position and an unlocked position, wherein the locking device is caught between the frame portion and the base portion when the locking device is in the locked position, thereby preventing the frame portion from tilting relative to the base portion, and Wherein the frame portion is inclined relative to the base portion when the locking device is in the unlocked position. In a third aspect, the present disclosure includes a seat comprising: a base, an inclined body coupled to the base to rotate the inclined body relative to the base; a cantilever bracket to the proximal end of the inclined body and a distal end; a frame coupled to the distal end, the frame supports a seat; and _ has a locking position and an unlocked position and is coupled to the inclined body, the cantilever bracket Or the locking device of the frame. [Embodiment] 125743.doc 200840517 As seen in FIGS. 1 to 6, a seat 100 incorporating a lightweight control tilt locking device generally includes four components, a frame portion 11 (), a base portion 12, and a Or a plurality of cantilever brackets 130, and a locking device 140. In Figure 1, frame portion 110 includes a seat 112 and a frame 114. The seat 112 is generally (but not necessarily) cushioned to support and support a person seated in the seat 100. Frame U4 is provided to support the structure of seat 112 and to connect seat 112 to one or more cantilevered supports 130. One or more cantilever brackets 13〇 allow the frame portion 11〇 to be tilted rearward relative to the base portion 120. • In FIG. 1, the base portion 120 includes a base 122 and an inclined body 124. The base 122 supports the seat 1〇〇 on the ground and is generally wider at its bottom than the widest portion of the seat 1〇〇. This configuration helps to prevent the seat 1〇0 from being tipped over by the person sitting in the seat 1,, thereby improving the stability of the seat 1〇〇. In FIG. 1, the inclined body 124 includes a mechanical shaft 125, an inclined body 126, and a head 127. The mechanical shaft 125 is generally a cylindrical rod extending downward from the inclined body 126 and is shown in phantom in Figures 1 and 2 . In FIG. 1, the mechanical shaft 125 is mounted in the bore of the top of the base 122 and is rotatable within the base 122 such that the ramp body 124, the lub bracket 130 and the frame portion 11 can be rotated 36 degrees relative to the base ι22. . In FIG. 1, the inclined body 126 extends away from the mechanical shaft 125 in both the horizontal and vertical directions. Thus, in Figure 1, the slant body 126 is raised and extended to provide a slanted or beveled support away from the (forward) pedestal 122. The horizontal and vertical aspects of the inclined body 126 allow the frame 114 to be positioned over the inclined body 126 with space to mount the block 148 between the frame n4 and the inclined body 126, which is hereinafter A more detailed description of the features. The head 127 of Figure 1 connects the inclined body 124 to at least one cantilever branch 125743.doc 200840517 frame 130. If the seat 1 is equipped with a plurality of cantilever brackets 13 , the head 127 can extend outwardly (toward the side) away from the body of the inclined body in a horizontal plane to form a sufficient space between the plurality of cantilever brackets 130 (provided The space is used to lock the device 14G) as shown in FIG. Two examples of the inclined body 124 are those issued to Sulzer on February 11th, the year of the year, and the application of Sulzer, the US Patent No. D422, 814 and July 1, 2004. U.S. Patent No. D. 52, No. 78, issued to Suizer, issued to Su.S., the entire disclosure of each of which is incorporated herein in The portion 11 is tilted relative to the base portion 120. It will be understood by those skilled in the art that the frame portion 11 can be tilted at any angle relative to the horizontal. In a particular embodiment, the angle of inclination is 5 degrees, 1 degree. , 15 degrees, 2 degrees, 25 degrees, 3 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 6 degrees or any other angle. Although any number of cantilevers can be used in the seat 100 The bracket 13〇, but the seat 100 is configured with two cantilever brackets 13〇 in Figures 1, 3 and 5. In Figure t, the cantilever bracket 130 is bolted, welded or otherwise at its proximal end 132 Attached to the inclined body 124 and bolted, welded or otherwise connected to the frame 1 at its distal end 134 14. These connections are generally rigid connections such that, for example, the distal end 134 moves vertically as a unit with the frame 114. In the figure, the cantilever bracket 130 is a generally rectangular piece of flat material that is operable to weight Lower flexing allows the frame portion 11 to tilt relative to the base portion 1. By attaching the frame 114 to the distal end 134 of the cantilever bracket no (away from the attachment of the cantilever bracket 130 to the head 127 of the inclined body 124), the seat The chair is designed to be tilted rearward (such as by the seated person leaning back into the seat 125743.doc 200840517) when applying sufficient weight to the frame portion 110 (backward, toward the reclined position). Referring to the cantilever bracket 130 of Figure i, The proximal end generally refers to the end 132 facing the frontal direction of the seat, and the distal end generally refers to the end 丨 34 facing the back of the seat tree (but it is generally understood by those skilled in the art that the specific orientation of these terms may be Any and these terms may be used to describe any two opposite ends of the assembly.) While a variety of materials are suitable for making cantilevered supports, the preferred material for Figure 1 is metal, especially for inscriptions, iron or steel. The skilled person is able to select a particular grade and material thickness of the material necessary to achieve the desired amount of tilt based on a number of factors including, but not limited to, the weight of the person sitting in the seat sill, the frame portion The weight of 110, the amount of tilt required, the length of the cantilever bracket 130, and the design of the seat. Also, although the front of the seat 100 is generally referred to herein as the proximal end and the back of the seat 100 is generally referred to as the distal end, generally Those skilled in the art will appreciate that the specific orientation of the terms in the near and far is arbitrary and can be used to describe any two opposite ends of the components of the seat 100. The locking device 140 of FIG. 1 includes one or more brackets 15A, a body 142, an arm 144, a handle 146, and a body 148. The bracket 15 of FIG. 1 clamps or is otherwise fastened to the inclined body 124 and slidably slidably to the lock δ and the body 142 so that the body 142 can be advanced relative to the inclined body 124 Slide (in the proximal direction) and backward (in the distal direction). The bracket 150 of Figure 1 generally secures the body 142 in place while also providing sufficient frictional resistance to movement of the body 142 to prevent the locking device 14 from unintentionally sliding out of its locked position. The block 148 of Figure 1 is coupled to the distal end of the body 142 and generally prevents the frame portion 110 from tilting relative to the base portion 120 when the locking device 140 is positioned in the locked position (because the block ι 48 supports the cantilever bracket 125743.doc 200840517 130 The distal end 134, the body 148 is a support section that limits the downward deflection of the cantilever bracket). In Figure 1, the block is approximately the height of the gap between the inclined body 126 and the unflexed cantilever support 130. Thus, when the locking device 140 of Figure 1 is in its locked position (the block 148 is in the proximal position, wedged between the cantilever bracket 130 and the inclined body 126), the block 148 is generally similar to the frame

In the figure, the arm Μ* is attached to the proximal end of the body 142 and extends from under the seat 112. Preferably, the arm (4) extends from the front of the seat, but it will be understood by those skilled in the art that the seat 100 can be assembled such that the arm 144 extends out of one of the sides of the seat 112 or the position 112 back. Regardless of the position of the arm 144 of Figure 1, a handle 146 can be mounted as appropriate to facilitate simple user actuation of the locking device 14G between the locked position and the unlocked position. Although not shown in Fig. 2, the block 148 may also be configured with at least one pad 149 on its top and/or bottom surface. The liner 149 is typically made of a material that is softer than the material used in the inclined body 124 and/or the frame ι 4, thus preventing the block 148 from scratching or slanting the inclined body 124 and/or the frame 114. Optionally, (iv) may also be made of a material having a high coefficient of friction to help secure the block in its locked position. In a particular embodiment, the liner 149 is a material such as polypropylene, poly §, or a polymeric material. 1, 3, 4, 7, and 8 show various views of the locking device 14G in an unlocked position. In the unlocked position, the handle 146 is positioned closer to the inclined body 124 and can be hidden under the seat 112. Additionally, the block 148 is positioned away from the frame 114 and the vicinity of the inclined body 124 when in the 125743.doc 200840517 unlocked position such that the block 148 does not obstruct the tilting movement of the frame portion 110. In other words, in the unlocked position, the block 148 does not contact at least one of the cantilever bracket 13 or the inclined body 120 such that the range of motion of the cantilever bracket 13 (downward deflection) is not limited by the block 148. Thus, when the locking device 14 is in the unlocked position, a person seated in the seat 100 can lean back against the back of the seat 112 or otherwise apply rearward or downward pressure to the back of the seat 112 to cause the frame portion 11〇 is inclined with respect to the base portion 12〇 without the locking device 140 to hinder the tilt. When a person sitting in the seat 1 of FIG. 1 wishes to prevent the seat 1〇0 from tilting, the person changes the locking device 14 from the unlocked position by actuating the locking device 14〇 in the forward direction. Lock the position. More specifically, the person pulls the handle 146 forward (in the proximal direction), which also causes the arm 144 to move forward. The forward movement of the arm 144 causes the body 142 of the locking device to slide forward through the bracket 150 and pull the block 148 to a position between the frame 114 and the inclined body 124. In other words, the block 148 of Figure 1 contacts both the cantilever bracket 130 and the angled body 124 to limit the range of motion of the cantilever bracket 130 (to obstruct the ability of the distal end 134 to flex downward). In general, during this actuation process, a person sitting in the seat 100 should not lean back against the back of the seat 112 or otherwise apply rearward or downward pressure to the back of the seat 112. In some cases, it may be necessary for the locking device 140 to even urge the person sitting in the seat 1 forward or otherwise apply a forward or upward pressure on the back of the seat 112 to fully actuate Locking device 140° 125743.doc -11- 200840517 Figures 2, 5, 6, 9, and 10 show various views of the locking device 140 in the locked position. In the locked position, the handle 146 is positioned relatively far away from the inclined body 124 and generally extends below the seat 100 (as seen in Figure 6). In addition, the block 148 of FIG. 2 is positioned between the frame 114 and the inclined body 124 such that the fixed block 14 is vertically secured to the distal end 134 of the cantilevered bracket relative to the base portion such that the distal end 134 is unable to The lower deflection limits the deflection of the cantilever bracket 13〇. Thus in the locked position of the locking device 140, it limits the frame portion 110 from tilting relative to the base portion 120 (backward) even though the person sitting in the seat 1可能 may lean back against the back of the seat 112 or otherwise The same is true when applying a backward or downward pressure to the back of the seat 112. When a person sitting in the seat 100 wishes to tilt the seat 100, the person changes the locking device 14 from the locked position to the unlocked position by actuating the locking device 14 in the rearward direction in FIG. More specifically, the person pushes the handle 146 rearward, which also causes the arm 144 to move rearward. The rearward movement of the arm 144 causes the body 142 to slide rearwardly through the bracket 150 and push the block 148 away from between the frame 114 and the inclined body 124. In general, during this actuation process, a person sitting in the seat 100 should not lean back against the back of the seat 112 or otherwise apply rearward or downward pressure to the back of the seat 112. In some cases, it is necessary for the locking device 140 to even forward or otherwise apply a forward or upward pressure to the back of the seat 112 by a person sitting in the seat 100 to begin toward the unlocked position. Dynamic Locking Device 140 The locking device 140 is shown in more detail in Figures 11-15. 11 and 12 illustrate the block 148, body 142, arm 144 and handle 125743.doc -12 - 200840517 146 of the locking device 140. Block 148 is located on the rear side of body 142 and may include a hole (not shown) to allow insertion of pad 149 (shown in Figures 3-6) into block 148. When the locking device 140 is mounted on the base portion 12, the body 142 can be inclined relative to the horizontal line such that it is substantially parallel to the surface of the inclined body 124. This configuration improves the aesthetic appearance of the seat 1 by minimizing the appearance of the locking device 14〇. Additionally, the arm 144 can be generally horizontal such that the arm 144 does not contact the seat 112 when the person actuates the arm 144 between the locked position and the unlocked position. The handle 146 is attached to the end of the arm 144 and can be tilted upward to improve the ergonomics and/or operability of the locking device 140. If desired, the decorative logo or the indication for actuating the locking device i 4 can be stamped or otherwise placed on the front side of the handle 146. The handle can be padded to improve ergonomics, as appropriate. 13 to 15 illustrate the bracket 15 of the locking device 14 . The bracket 150 in these figures connects the remainder of the locking device 140 to the ramp 124 and includes a plurality of clamps 152, a lower rail 154, and an upper guide 156. The clamp 152 is configured to wind the sides and underside of the inclined body 124, thereby fastening the bracket 150 to the inclined body 124. Those of ordinary skill in the art will appreciate that the brackets 15 5 do not necessarily have to be taut to the inclined body 124. More correctly, the bracket 150 can be coupled to the frame portion 110, the base portion 20, the cantilever bracket 130, or a combination of both, by any suitable attachment means such as a screw, bolt, weld, and/or adhesive. Lower rail 154 is configured to conform to the upper surface of ramp body 124 and is positioned below body 142 such that it acts as a lower support for body 142. In one embodiment, body ι 42 slides across at least a portion of the upper surface of lower guide 154. Upper rail 156 acts as a guide for the upper surface of body I25743.doc -13 - 200840517 142 such that body 142 is positioned below at least a portion of upper guide 156. In one embodiment, the body bore 42 slides through the bracket 150 by sliding across at least a portion of the lower surface of the upper rail 156. The bracket 150 can be configured with an additional lower guide 154 or upper rail 156 as necessary. Accordingly, the brackets 150 of these figures can be used to secure the locking device 140 in position in the straight and horizontal directions while enabling the body 142 to slide from the locked position to the unlocked position. 16 through 22 illustrate an alternate embodiment of a lightweight control tilt lock. An alternative embodiment of the locking device 140 is similar to the previous embodiment of the locking device 140. The difference is that an alternative embodiment of the locking device 140 includes a plurality of fingers 160 as an alternative to the bracket 150. As can be seen in Figure 22, the fingers 160 are positioned on either side of the body 142 and on the top and bottom surfaces of the body 142. If desired, the locking device 140 can be configured with more fingers 160 than shown in the drawings. When the locking device ι4 〇 is mounted on the seat 100, the fingers 160 extend above and below each of the cantilever brackets 13 and maintain the locking device 14 定位 between the cantilever brackets 〇3〇. The fingers 160 also allow the locking device 140 to slide forward or backward along the cantilever bracket 13 . The travel of the locking device 140 along the cantilever bracket 130 can be limited in the forward direction by the head 127 of the inclined body 124 and in the rearward direction by the frame U4. Preferably, an alternate embodiment of the locking device 140 is configured such that the locking device 140 is in the locked position when the finger 160 contacts the head 127 and is in the unlocked position when the finger 160 contacts the frame 114. However, those skilled in the art will appreciate that alternative embodiments of the locking device 14 can be configured such that the locking device 140 is unlocked when the finger 16 turns into contact with the head 127. 125743.doc • 14- 200840517 The position is in the locked position when the finger 160 contacts the frame 114. The various components illustrated and discussed herein can be made from any type of material and can be made by any acceptable method. By way of example, various components may be made of wood metal, plastic, other materials, or combinations thereof. These components can be made by grinding, casting, forging, extrusion, any other manufacturing method, or a combination thereof. In one embodiment, the components are aluminum and are fabricated in a molding process. One of the methods of die-cast aluminum assembly is described in U.S. Patent No. entitled "System for Manufacturing Die Castings" by Fuh〇n et al.
