[0002] SUMMARY The present disclosure relates to a portable container with a latching system. [Background technology]
[0003] Many different types of containers and latching systems exist. Containers can be used for food, beverages, and other materials or items. Latching systems exist for locking the containers closed. However, conventional containers and latching systems are often not durable and difficult to use. For example, the containers may not be sturdy enough to hold certain items, and may not be sturdy enough to hold items on the containers. Additionally, some latching systems engage when the user does not want the system to engage, and in other cases, do not provide sufficient locking between the containers. These and other deficiencies in such devices render the containers and / or latching systems virtually useless. Summary of the Invention
[0004] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
[0005] One aspect of the present disclosure relates to a container comprising: (a) a base including: (1) a sidewall structure having at least a first side and a second side opposite the first side, the sidewall structure having a first end and a second end opposite the first end; (2) a bottom portion connected to the first end of the sidewall structure and configured to support the container on a surface; and (3) a base opening formed in the second end of the sidewall structure, the base opening configured to allow access to an interior cavity of the container formed by the sidewall structure and the bottom portion; (b) a lid pivotally connected to the base, the lid having a shape corresponding to a shape of the base and configured to rotate between an open state that allows access to the base opening and a closed state that prevents access to the base opening; and (c) a latch assembly having a locked position and an unlocked position. The latch assembly may include (a) a latch body pivotally connected to the lid, (b) a latch button having a latch button locking member slidably connected to the latch body, (c) a latch lock arm having a latch arm locking member pivotally connected to the latch body, (d) a latch button biasing member that applies a linear force to the latch button, and (e) a latch lock arm biasing member that applies a rotational force to the latch lock arm. To move the latch assembly to the locked position, the latch lock arm engages the base and rotates against the rotational force of the latch lock arm biasing member, and the latch button moves against the linear force of the latch button biasing member, after which the latch button locking member engages the arm locking member. Additionally, the latch button locking member engages the arm locking member when the latch lock arm is in a substantially vertical position. In an exemplary embodiment, the latch lock arm biasing member is a torsion spring. The latch arm locking member may include a first locking surface and a curved upper surface extending from an upper edge of the first locking surface, and the latch arm locking member may be substantially centered along the latch lock arm. The latch lock arm may have a pair of engagement members located on each side of the arm locking member, and each engagement member of the pair of engagement members may be spaced apart from the arm locking member.Additionally, each of the pair of engagement members of the latch lock arm may have an end with a curved surface that engages with a receptacle positioned below the lip extending along the first side of the base. The latch assembly may include a mating pawl that is rotatably attached to the latch body and positioned closer to the upper edge of the latch body than the lower edge of the latch body. The mating pawl includes a central member with a hole extending through the base, a first protrusion extending outward from the central member, and a second protrusion extending outward from the central member opposite the first protrusion. The first protrusion of the mating pawl can contact the latch button to prevent upward movement of the latch button when the latch assembly is in the unlocked position. The second protrusion of the mating pawl may have a curved outer surface that contacts the lid to prevent locking of the latch assembly before the lid is closed when the latch assembly is in the unlocked position. The latch assembly may include a third biasing member that applies a second rotational force to the mating pawl. In some examples, the container may include a divider that extends across the lid opening of the lid, the divider being pivotally connected to the lid. The divider may be connected to the lid by a hinge and selectively secured to the lid on a side opposite the hinge to prevent rotational movement of the divider. The divider may be removably secured to the lid by a snap fit. The divider may include a plurality of elongated openings.
[0006] Another aspect of the present disclosure relates to a container comprising: (a) a base including: (1) a base sidewall structure having at least a first side, a second side opposite the first side, a first end, and a second end; (2) a bottom portion connected to the first end of the base sidewall structure and configured to support the container on a surface; and (3) a base opening formed in the second end of the base sidewall structure, the base opening configured to allow access to an interior base cavity of the base formed by the base sidewall structure and the bottom portion; and (b) a lid pivotally connected to the base, the lid having (1) at least a first side and a second end. The device includes: (1) a lid sidewall structure having a second side opposite the first side, a first end, and a second end opposite the first end; (2) an upper portion connected to the second end of the lid sidewall structure; (3) a lid opening formed in the first end of the lid sidewall structure, the lid opening configured to allow access to a lid interior cavity formed by the lid sidewall structure and the upper portion; (4) a lid including a divider pivotally connected to an interior portion of the lid, the divider separating a base interior cavity from a lid interior cavity; and (c) a latch assembly pivotally connected to the lid, the latch assembly having a locked position and an unlocked position. The divider may include a front side, a rear side, a first side including an associated hinge, and a second side opposite the first side, the associated hinge being connected to a hinge receiving portion of the lid. The lid may be configured to rotate between an open state that allows access to the base opening and a closed state that blocks access to the base opening. The second side of the divider may include a centrally located recess forming a pair of tabs, each tab including an engaging receptacle. The engaging receptacle forms a friction fit with a lid engaging member extending from an inner surface of the lid to prevent rotational movement of the divider. In some examples, the divider may include a plurality of elongated openings extending across a portion of the front side of the divider in a direction from the first side of the divider toward the second side of the divider.The latch assembly for the container may include (a) a latch body pivotally connected to the lid, (b) a latch button having a latch button locking member slidably coupled to the latch body, (c) a latch lock arm having an arm locking member pivotally connected to the latch body, (d) a latch button biasing member that applies a linear force to the latch button, and (e) a latch lock arm biasing member that applies a rotational force to the latch lock arm. When the latch assembly is moved to the locked position, the latch lock arm engages the base and rotates against the rotational force, and the latch button moves against the linear force, after which the latch button locking member engages the arm locking member.

Where the same reference number appears in more than one drawing, that reference number will be used consistently herein and the drawings will refer to the same or similar parts throughout.
[0013] 1-15 show various views of a container 100. The container 100 may include a base 110 and a lid 150, which in some instances may be coupled to the base 110 or in some instances may be non-destructively removably coupled to the base 110. The base 110 may be a structure that forms a cavity for receiving an item, as described more fully herein. In some instances, the base 110 may be rectangular or substantially rectangular in shape. In other instances, the base 110 may be truncated or substantially truncated (e.g., a square prism, a pentagonal prism, a hexagonal prism, a heptagonal prism, etc.) in shape. In yet other instances, the base 110 may have a substantially cylindrical shape or a substantially trapezoidal cross section. Various other shapes may be used without departing from this invention.
[0014] The base 110 may include a base sidewall structure 112 having a first side 114, a second side 116 opposite the first side 114, a third side 118 extending between an edge of the first side 114 and an edge of the second side 116, and a fourth side 120 opposite the third side 118. The base sidewall structure 112 may include a first end 124 and a second end 122, with a bottom portion 126 connected to the first end 124 of the base sidewall structure 112. The bottom portion 126 may be configured to support the container 100 on a surface such as a table, ground, or the like. In some embodiments, the bottom portion 126 may include and / or includes a support member 128. The support member 128 may be attached to the bottom portion 126 to help provide a non-slip surface for the container 100. Support member 128 may be a separate member that can be integrally formed with base 110 or that can be attached to base 110 after base 110 is formed. Support member 128 may be sized to occupy at least 50% of the surface area of bottom portion 126. Although not shown, in some embodiments, support member 128 may include a plurality of legs disposed on bottom portion 126.
[0015] The base 110 may include a base opening 130 at the second end 122 of the base sidewall structure 112 (see FIGS. 3-5). The base opening 130 is configured to allow access to a base interior void 132 formed by the base sidewall structure 112 and the bottom portion 126.
[0016] The container 100 may include a lid 150. The lid 150 may be pivotally connected to the base 110 and may be configured to rotate between an open state and a closed state, where the open state allows access to the base opening 130 and the base interior cavity 132 and the closed state prevents access to the base opening 130 and the base interior cavity 132. In some examples, rotating the lid 150 from the closed state to the open state includes rotating the lid approximately 90° from the closed state, approximately 180° from the closed state, or approximately 270° from the closed state. As shown in FIG. 1 , when the container 100 is in the closed state, the base opening 130 may be covered by the lid 150. In some arrangements, the lid 150 may be connected to the base 110 in the closed state using a press fit. Additionally or alternatively, a different fastening system or device may be used to secure the lid 150 to the base 110, as described more fully herein.
[0017] In some examples, the lid 150 may be hinged such that the lid 150 is connected (removably or permanently) to the base 110 at the hinge 142 and may be rotated about the hinge 142. The hinge 142 may be one of a variety of different types of hinges, including a continuous piano hinge, a double hinge, a ball joint hinge, a living hinge, etc. These hinges and a variety of other hinge devices may be described more fully herein. The hinge 142 may allow the lid 150 to be opened and rotated away from the base 110 to provide access to the base interior cavity 132 defined by the base 110 (e.g., through the base opening 130). That is, the hinge 142 can facilitate rotation of the lid 150 from a closed state of the container 100 (e.g., as shown in FIG. 1, where the lid 150 is in a position covering the base interior void 132 formed by the base 110) to an open state (e.g., as shown in FIGS. 3-5, where the lid 150 is not covering the base interior void 132 formed by the base 110), and vice versa.
[0018] The lid 150 may include a lid sidewall structure 152 having a first side 154, a second side 156 opposite the first side 154, a third side 158 extending between an edge of the first side 154 and an edge of the second side 156, and a fourth side 160 opposite the third side 158. The lid sidewall structure 152 may include a first end 162 and a second end 164, with an upper portion 166 connected to the second end 164 of the lid sidewall structure 152. The upper portion 166 may be configured to function as a cover for the container 100 that can support an item placed on the container 100. In some examples, the upper portion 166 may have a recess 168 centrally located along the upper portion 166 so that a second container can be placed on the upper portion 166. Additionally, the lid 150 may include a lid opening 170 at the first end 162 of the lid sidewall structure 152. The lid opening 170 is configured to allow access to a lid interior void 172 formed by the lid sidewall structure 152 and an upper portion 166 at the second end 164 of the lid sidewall structure 152. In most instances, the height of the lid sidewall structure 152 may be less than the height of the base sidewall structure 112. Thus, the volume of the base interior void 132 may be greater than the volume of the lid interior void 172.
[0019] In some arrangements, the container 100 may include a gasket 199 or another sealing device. The gasket 199 may be located on either the lid 150 or the base 110 and may assist in sealing the lid 150 to the base 110 when the lid 150 is in the closed position. For example, in one example, the container 100 may be manufactured to be dustproof when tested for eight hours and / or waterproof when tested at a depth of one meter for 30 minutes. In some embodiments, the container 100 may achieve an IP68 rating (as defined by the International Electrotechnical Commission), which specifies that the container is dust-tight or completely dust-protected when tested for eight hours and is unable to allow harmful amounts of water to enter when the enclosure is immersed in water under specified pressure and time conditions (one meter of submersion). The IP68 dustproof test is eight hours long, and the enclosure is tested in a vacuum. The IP68 water resistance test is 30 minutes long and the enclosure is tested with the lowest point of the enclosure in 1 meter of water.
[0020] In some examples (and as best shown in FIGS. 12-14 ), a gasket 199 may seat in a recess 174 formed in the lid 150 that extends around the periphery of the lid 150. Additionally, in some examples, the container 100 may include a raised portion 134 on the base 110. The raised portion 134 extends around the periphery of the base 110. The gasket 199 may be disposed between the recess 174 and the raised portion 134. When the lid 150 is in the closed position, the raised portion 134, which has a shape corresponding to the recess 174, may contact the gasket 199, compressing the gasket 199 and helping to seal the lid 150 and base 110 in the closed position as shown in FIGS. 12-14 . In some examples, the gasket 199 may be a conventional gasket having a substantially circular cross-section. In another arrangement, the gasket 199 may include strategically placed notches that can reduce or eliminate the need for vents (e.g., vents to prevent the lid from locking). The gasket 199 can assist in maintaining a seal between the interior of the container 100 and the outside environment, and in some examples, the gasket 199 can assist in maintaining the temperature of items contained within the container 100. Alternatively, the gasket 199 may be disposed within a recess or channel formed in the base 110.
[0021] The container 100 may include additional features, such as a lanyard 198 shown in FIG. 2 , to allow a user to carry the container 100 or attach the container 100 to another object. The lanyard 198 may be connected to the base at the third side 118 and extend along the bottom portion 126 to the fourth side 120. As shown in the illustrated example, the support member 128 may have a groove 136 (or a pair of grooves) that receives and guides the lanyard 198 along the bottom portion 126. Additionally, the third side 118 and the fourth side 120 of the base sidewall structure 112 may include guide rails 138 for engaging the lanyard 198 and guiding it along the third side 118 and the fourth side 120. The base sidewall structure 112 may also include a connecting member 140 adjacent the guide rail 138 for securing the lanyard 198 to the base 110 of the container 100. The guide rail 138 and the connecting member may be integrally formed with the base 110.
[0022] As shown in Figures 3, 4, 5 and 12-15, the lid 150 may include a divider 178 pivotally connected to an interior portion of the lid 150, separating items that may be stored within the lid interior cavity 172 from the base interior cavity 132. The divider 178 may extend across the lid opening 170, separating the base interior cavity 132 from the lid interior cavity 172. The divider 178 may have a front side 179 and a back side 180 and a mounted hinge 181 formed along a first side 182, the hinge 181 being pivotally connected to the lid 150 at a hinge receiving portion 175 of the lid 150. The mounted hinge 181 may include a plurality of holes spaced from an edge of the first side 182. Additionally, the built-in hinge 181 may be disposed at a predetermined angle relative to the front side 179 and may snap into the hinge receiving portion 175 of the lid 150 to secure the divider 178 to the lid 150. The divider 178 may include a plurality of elongated apertures 184. The elongated apertures 184 may extend across a portion of the divider 178 in a direction generally directed from a first side 182 toward a second side 183 opposite the first side 182. Each elongated aperture 184 may have a length L that extends across at least 50% of the width W of the divider 178, or in a range of 55% to 80% of the width W, where the width W is the distance from the first side 182 to the second side 183. Alternatively, the divider 178 may be a continuous surface without any apertures.
[0023] Once the divider 178 is installed, a second side 183 of the divider 178 may be selectively secured to the lid 150, as best shown in FIG. 15 , to prevent rotational movement of the divider 178. Along the second side 183, the divider 178 may include a central recess 185 that forms a pair of tabs 186. Each tab 186 may have an engagement receptacle 187 that forms a friction or snap fit with a lid engagement member 177 extending from the inner surface of the lid 150. The lid engagement member 177 may fit within a groove formed by the engagement receptacle 187 of the divider 178.
[0024] The container 100 may include a removable tray 188. The tray 188 may allow a user another level for storing items in the container 100. The tray 188 rests along a shelf 148 that extends along the inner periphery of the base interior cavity 132. The tray 188 may include an upwardly extending portion 190 with a peripheral wall 192 that extends from an inner edge 194 of the upwardly extending portion 190 to a bottom wall 196 that forms the bottom portion of the tray 188. The volume formed by the tray's peripheral wall 192 and bottom wall 196 may form an upper storage area of the base interior cavity 132. The tray 188 may have a tray depth that is less than the depth of the base sidewall structure 112 of the base 110, such that the bottom wall 196 of the tray 188 is spaced from the bottom portion 126 of the base 110, which allows for a secondary storage area within the base interior void 132 below the bottom wall 196 of the tray 188. As mentioned above, the tray 188 is removable, and when the tray 188 is removed, the base interior void 132 may form a sole storage area within the base 110.
[0025] The upward ridge 190 may be continuous along the perimeter wall 192 to form a solid upward ridge 190. Similarly, the perimeter wall 192 and the bottom wall 196 may be continuous such that no holes or apertures are present in the tray 188. Alternatively, the perimeter wall 192 and / or the bottom wall 196 may include apertures. In some examples, the ledge 148 may be continuous along the inner perimeter of the base interior cavity 132, while in other examples, the ledge 148 may be interrupted or multiple mounts (not shown) may be positioned along the inner surface of the base sidewall structure 112 to form a flat surface for supporting the tray 188.
[0026] The dividers 178 and trays 188 may have an elastomeric material coating to provide a soft touch and feel and to store delicate objects. The dividers 178 and / or trays 188 may be overmolded onto a more rigid base, or in some cases, the dividers 178 and / or trays 188 may be formed from an elastomeric material. The elastomeric material used to form or partially form the exemplary dividers 178 and / or trays 188 may be or include materials such as natural and synthetic rubber, thermoplastic urethane (TPU), thermoplastic elastomer (TPE), or another similar material.
[0027] In some arrangements, the container 100 may include a latch assembly 200. As best shown in FIGS. 16A-20 , the latch assembly 200 may have a locked position and an unlocked position, and the latch assembly 200 is configured to lock the lid 150 when the lid 150 is in a closed position. The latch assembly 200 may include a latch body 210 pivotally connected to the lid 150, a latch button 230 slidably connected to the latch body 210, and a latch lock arm 250 pivotally connected to the latch body 210 about a latch pin 270 connected to the latch body 210. The latch assembly 200 may include a latch button biasing member 280 that applies a vertical force to the latch button 230 and a lock arm biasing member 282 that applies a rotational force to the latch lock arm 250. The latch button 230 may include a latch button locking member 232, and the latch lock arm 250 may include an arm locking member 252. In some examples, the latch assembly 200 may further include a mating pawl 288 that is rotatably attached to the latch body 210 via a pin connection, where the mating pawl 288 is located closer to the top edge 212 of the latch body 210 than to the bottom edge 214 of the latch body 210. As described in more detail below, when the latch assembly 200 is moved to the locked position, the latch lock arm 250 engages the base 110 and rotates against the rotational force of the lock arm biasing member 282, and the latch button 230 moves against the vertical force of the latch button biasing member 280, after which the latch button lock member 232 engages the arm lock member 252, as shown in FIGS.
[0028] 16A-16D illustrate movement of the latch assembly 200 from the unlocked position to the locked position. As shown in FIG. 16A, the latch assembly 200 is in the unlocked position with the latch lock arm 250 extending away from the latch body 210 toward the base 110. The mating pawl 288 can prevent the latch lock arm 250 from unintentionally engaging the latch button 230 and entering its locked position when the container 100 is in an open state (e.g., the base 110 and lid 150 are separated from one another on at least one side). The mating pawl 288 can include a central member 290 having a hole 292 extending therethrough, a first protrusion 294 extending outwardly from the central member 290, and a second protrusion 296 extending outwardly from the central member 290 opposite the first protrusion 294. The first protrusion 294 can contact the latch button 230 when the latch assembly 200 is in the unlocked position, thereby preventing the latch button 230 from moving upward toward the upper edge 212 of the latch body 210. The second protrusion 296 of the mating pawl 288 can have a curved outer surface that can contact the lid 150 when the latch assembly 200 is in the unlocked position, thereby preventing the latch lock arm 250 from locking before the lid 150 is in the closed state. Additionally, a pawl biasing member 298 can apply a rotational force to the mating pawl 288 to keep the mating pawl 288 in contact with the latch button 230 when the container 100 is in the open state. Because the latch button 230 cannot slide, the latch lock arm 250 cannot rotate and unintentionally engage the latch button 230 before the lid 150 is closed on the base 110. For example, the pawl biasing member 298 may be a torsion spring that applies a rotational force to bias the first projection 294 toward the latch body 210 (i.e., in a clockwise direction as shown in FIG. 16A ). The rotational movement of the mating pawl 288 may be controlled by a cam-like interaction between the outer surface of the second projection 296 of the pawl 288 and the lid 150.In some examples, the corresponding engagement region 176 includes a corresponding curved surface for engaging a curved outer surface of the second protrusion 296 .
[0029] 16B and 16C illustrate the latch assembly 200 engaging the base 110, causing the latch assembly 200 to begin moving from the unlocked position to the locked position. When the lock arm engagement member 254 of the latch lock arm 250 engages the receptacle 144 positioned below the lip 146 extending outward along the first side 114 of the sidewall structure (as best shown in FIG. 13), the latch lock arm 250 begins to rotate toward the latch body 210 (i.e., the latch lock arm 250 rotates counterclockwise as shown in FIG. 16B). In some examples, the lip 146 may extend outward along the entire periphery of the base 110. The receptacle 144 may have a concave cross-sectional shape, and the lock arm engagement member 254 may have a convex cross-sectional shape. When the latch lock arm 250 contacts the base 110, the latch lock arm 250 begins to move below the base 110. Rotational movement of the latch lock arm 250 causes the latch button lock member 232 to contact and lift along the outer surface 258 of the arm lock member 252. Movement of the latch button lock member 232 along the outer surface 258 allows the latch button 230 to translate upward in a sliding motion toward the upper edge 212 of the latch body 210. Rotation of the latch lock arm 250 rotates the entire latch assembly 200 toward a vertical orientation.
[0030] 16D illustrates the latch assembly 200 in the locked position. In the locked position, the latch button lock member 232 engages the arm lock member 252, with the latch lock arm 250 oriented substantially vertically. Each lock member 232, 252 may include a locking surface 234, 256, respectively, that opposes each other when the latch assembly 200 is in the locked position. Furthermore, when in the locked position, each locking surface 234, 256 may be oriented substantially vertically. As the latch button lock member 232 moves the curved outer surface 258 of the arm lock member 252, the latch button lock member 232 eventually reaches an upper edge 260 of the curved outer surface 258. The upper edge 260 may be the upper edge of the locking surface 256, so that as soon as the latch button locking member 232 passes the upper edge 260 of the outer surface 258, the latch button locking member 232 drops, causing the locking surface 234 to move downwardly to face the locking surface 256 of the arm locking member 252.
[0031] To move the latch assembly 200 from the locked position to the unlocked position, the above process is reversed, as shown in FIGS. 17A-17C. A user can push the latch button 230 upward, disengaging the locking surface 234 from the locking surface 256. The lock arm biasing member 282 then rotates the latch lock arm 250 toward the base 110, causing the latch button locking member 232 to slide downward on the outer surface 258 of the arm locking member 252. Additionally, the latch button biasing member 280 applies a downward force to the latch button 230, thereby assisting in the extension of the latch button 230 and the latch button locking member 232 to slide downward on the outer surface 258 of the arm locking member 252. In some examples, the latch assembly 200 can operate without the mating pawl 288.
[0032] 18-20 illustrate the latch assembly 200 removed from the lid 150. As described above, the latch assembly 200 may include a latch body 210, a latch button 230 slidably connected to the latch body 210, and a latch lock arm 250 pivotally connected to the latch body 210 about a latch pin 270 connected to the latch body 210.
[0033] The latch body 210 may include an upper edge 212, a lower edge 214, and an outwardly facing surface 216 extending between the upper edge 212 and the lower edge 214. On an inner side 217 opposite the outwardly facing surface 216, the latch body 210 may further include a pair of hinge members 223, a latch pin receiving portion 218, a pair of latch button guides 220, and a button biasing member receiving portion 222. The hinge members 223 may be configured to receive a lid latch pin 272 to connect the latch assembly 200 to the lid 150. The latch pin receiving portion 218 may include a hole 228 disposed on a side surface 226 of the latch body 210 and may include a pin support 221 that receives the latch pin 270 on at least two sides. Additionally, each latch button guide 220 may be a protrusion located on either side of the latch button 230 to maintain movement of the latch button 230 in a linear orientation. The button biasing member receiving portion 222 may comprise a recess or a pair of recesses in the latch body 210 configured to retain a portion of the latch button biasing member 280. The latch button biasing member 280 may be a compression spring or a pair of compression springs for applying a linear force to the latch button 230 toward the bottom edge 214. This linear force helps to keep the latch button locking member 232 engaged with the arm locking member 252. In an exemplary latch assembly 200 that includes a mating pawl 288, the latch body 210 may further include a pawl receiving portion 224 that receives a pin and pawl biasing member 298.
[0034] The latch button 230 may include a latch button locking member 232 extending outward from a rear surface 236, while the front surface 238 may be configured to face against and slidably move along the inner surface of the interior side 217 of the latch body 210. The latch button 230 may further include a bottom surface 240 that provides an interface for a user to apply an upward force to disengage and / or engage the latch assembly 200. A latch button pin receiving portion 242 may be positioned above the bottom surface 240. The latch button pin receiving portion 242 may include a hole that receives the latch pin 270. The latch button pin receiving portion 242 may have a height greater than the diameter of the latch pin 270 to allow the latch button 230 to slide along the latch body 210 while the latch pin 270 is secured to the latch body 210. For example, the height of the latch button pin receiving portion 242 may be twice the diameter of the latch pin 270. In some examples, the height of the latch button pin receiving portion 242 may be in the range of 1.5 to 3 times the diameter of the latch pin 270. As another feature, the front surface 238 may include a recess that is configured to retain a portion of the latch button biasing member 280 and that is substantially aligned with the button biasing member receiving portion 222 on the latch body 210.
[0035] The latch button locking member 232 may be centered on the latch button 230 and may include a locking surface 234 extending substantially perpendicular to the bottom surface 240. The latch button locking member 232 may include a sliding surface 244 adjacent a lower edge of the locking surface 234, where the sliding surface 244 may be configured to slide along the outer surface 258 of the arm locking member 252. The sliding surface 244 may be disposed at an acute angle (i.e., in the range of 1 to 89 degrees) relative to the locking surface 234. In some examples, a stop 245 may extend from the top surface 246 of the latch button 230, where the stop is configured to contact the mating pawl 288 to prevent unintentional movement of the latch button 230 when the latch assembly 200 is in the unlocked position.
[0036] The latch lock arm 250 may have a front side 268 facing the latch body 210 and a rear side 269 facing the base 110. The latch lock arm 250 may include an arm lock member 252 substantially centered along the latch lock arm 250 and a pair of lock arm engaging members 254 located on each side of the arm lock member 252, where each engaging member 254 may be spaced apart from the arm lock member 252. Further, each engaging member 254 may have a free end 262 having a curved or convex cross-sectional shape that engages with the receptacle 144 on the base 110 and a fixed end 264 that receives the latch pin 270. The lock arm biasing member 282 may be a torsion spring or a pair of torsion springs that are connected to the latch pin 270 and apply a rotational force to the engaging member 254. 14, the free end 262 of each engagement member 254 may include a locking surface 266 that may confront and contact the locking member 149 positioned within the receptacle 144 of the base 110. The locking surface 266 may be substantially parallel to the locking surface 256 of the arm locking member 252 and may be spaced forward (toward the latch body 210) from the locking surface 256.
