Patent Application
20210123273
The present application relates to the field of door locks, and more particularly to portable door locks.
For typical public restrooms where a plurality of toilets are separated into stalls, each stall is enclosed by a hinged stall door that is locked typically using a latch that serves as a locking mechanism for securing the stall door to a stall wall. However, there are a variety of instances where the lock fails to secure the stall door to the stall wall, thereby creating an anxiety filled and potentially embarrassing restroom experience for a user. For instance, the latch may be missing entirely, the latch cannot reach a mating aperture that receives the latch, or the latch is able to reach the mating aperture, but the latch is permitted to slide out of the mating aperture. In these instances, the user must resolve to placing a hand against the stall door or otherwise vocalize the presence of the user to prevent another person from accidentally opening the stall door while the user is occupying the stall; however, this can put the user in an uncomfortable position and/or unnecessary stress on the user.
Therefore, a portable door lock is desired that can secure a public restroom stall door to a stall wall when the locking mechanism for securing the stall door to the stall wall is either missing or malfunctioned. Furthermore, it is desired that the portable door lock be in a form that is compact in order to reduce the inconvenience of carrying the portable door lock.
Embodiments of the present invention disclose a portable door lock assembly that prevents rotation of a hinged stall door away form a stall wall. In one embodiment of the present invention, an assembly is provided comprising: an elongated track member having a recess along a first face, the elongated track member including a stop at a first end, the stop having a width larger than a width of the elongated track member; and a foundation member having a body permitted to translate along the elongated track member, the foundation member including: an arm member extending outward from the body at an angle relative to an axis of the elongated track member; and a latch coupled to the foundation member and configured to selectively engage the recess of the elongated track member, the latch configured to selectively secure the foundation member to a position along the elongated track member.

In
Track member 107 has a first face (i.e. face 109), a second face (i.e., face 110) further depicted in
Furthermore, track member 107 has a first recess (i.e., recess 111a) located on face 109 with an optional further second recess (i.e., recess 111b) located on face 110, as seen in
Foundation member 101a and foundation member 101b have the same form and physical features unless explicitly stated herein. Foundation member 101a is coupled to end 114 of track member 107. Foundation member 101b has a body that is permitted to translate along track member 107. Latches 105a and 105b that are in communication with foundation member 101b are configured to selectively engage a corresponding recess of track member 107, wherein the latches are configured to selectively secure foundation member 101b to a position along track member 107. Additional features of foundation members 101a-b and associated components are further described and illustrated with respect to
Referring now to
Both foundation members 101a and 101b have a first face (i.e., face 125a and face 125b, respectively) and a second face (i.e., face 126a and face 126b, respectively). Furthermore, both foundation members 101a and 101b have an aperture (i.e., aperture 121a and 121b, respectively) that passes from the first face and the second face of each foundation member, wherein the aperture is configured to receive track member 107. Foundation member 101b is permitted to translate along track member 107 according to track member 107 passing through aperture 121a. Foundation member 101a is coupled to end 114 of track member 107. For example, foundation member 101a is coupled to end 114 by an adhesive material (e.g., glue or bonding agent) applied between aperture 121a and a portion of track member 107 that is located proximate to end 114, wherein the adhesive material permanently couples foundation member 101a to track member 107. In another example, foundation member 101a is coupled to end 114 via an interference fit between aperture 121a and a portion of track member 107 that is located proximate to end 114. In this example, aperture 121a of foundation member 101a is smaller than aperture 121b of foundation member 101b such that aperture 121a permits an interference fit between foundation member 101a and track member 107, while aperture 121b permits foundation member 101b to translate along track member 107.
Stop 115 of track member 107 is an end stop that prevents foundation member 101b from decoupling from track member 107. Stop 115 has a width (i.e., stop width 117) larger than a width of track member 107 (i.e., track width 119). Subsequently, the width of stop width 117 is larger than aperture 121a of foundation member 101b thereby preventing foundation member 101b from decoupling from track member 107 from end 113.
Foundation members 101a and 101b are oriented such that face 125a of foundation member 101a and face 125b of foundation member 101b are oppositely facing each other. Arm members 103a and 103b are coupled to foundation member 101a located proximate to face 125a, and arm members 103c and 103d are coupled to foundation member 101b located proximate to face 125b. Arm members 103a and/or 103b extend outward from foundation member 101a at an angle relative to axis 123. Arm members 103c and/or 103d extend outward from foundation member 101a at an angle relative to axis 123.
Each arm member is configured to pivot relative to each foundation member about an arm axis for compact storage and transportation. For example, as illustrated in
Optionally, in its most distilled form without sacrificing functionality, portable door lock assembly 100 may have one arm member in communication with each foundation member, wherein respective arm members are opposite across track member 107. For example, foundation member 101a has arm member 103b while foundation member 101b has arm member 103c, or foundation member 101a has arm 103a while foundation member 101b has arm member 103d.
Optionally, portable door lock assembly 100 may not have foundation member 101a, but instead have foundation member 101b oriented such that arm members 103c and 103d are located on a face of foundation member 101b closest to stop 115 (i.e., face 125b is oriented to face towards stop 115). In this orientation, portable door lock assembly 110 holds a hinged public restroom stall door in a closed position with respect to a restroom stall wall by positioning the stall door and the stall wall between arm members 103c-d and stop 115.
Optionally, portable door lock assembly 100 does not include an end stop.
Referring now to
In this figure, foundation member 101b is translated away from foundation member 101a until face 126a of foundation member 101b is in contact with stop 115. In this position, one or more arm members corresponding to each foundation member may pivot with respect to corresponding axes to permit compact storage and transportation. For example, arm member 103b and arm member 103d are permitted to pivot with respect to axis 127b and axis 127d such that arm member 103b and 103d are permitted to be planarly flush against track member 107.
Referring now to
One or more latches in communication with foundation member 101b are configured to pivot so as to selectively engage a corresponding one or more recesses located along track member 107, the one or more latches permitting selective translation of foundation member 101b along track member 107. For example, in
The one or more latches are spring biased to maintain contact with track member 107 when at rest. For example, in
While the one or more latches are engaged with one or more recesses of track member 107, the engagement between the one or more latches with the corresponding one or more recesses prevents foundation member 101b from translating a direction along track member 107, wherein the direction is away from end 114 of track member 107.
Referring now to
In this figure, latch 105a and 105b are disengaged from track member 107 such that latch 105a and 105b are compressed against the spring of each latch that maintains contact with track member 107, thereby disengaging latch tooth 106a and latch tooth 106b from corresponding recesses 111a and 111b, subsequently permitting foundation member 101b to translate along track member 107.
Referring now to
In this figure, stall door 211 is a hinged door that is in a closed position relative to stall wall 201. In this figure, a user has positioned portable door lock assembly 100 between stall door 211 and stall wall 201 to lock stall door 211 in the close position.
In this figure, stall wall 201 has a front side (i.e., side 203a), a back side (i.e., side 203b), a first end (i.e., end 205), and a second end (i.e., end 207). Furthermore, stall door 211 has a front side (i.e., side 213a), a back side (i.e., side 213b), a first end (i.e., end 215), and a second end (i.e., end 217). Portable door lock assembly 100 is positioned between stall door 211 and stall wall 201 such that track member 107 is in between planar surfaces of stall door 211 and stall wall 201, and foundation member 101b is translated into a position where one or more arm members of foundation member 101b are planarly flush with side 203b of stall wall 201 and side 213b of stall door 211, and one or more arm members of foundation member 101a are planarly flush with side 203a of stall wall 201 and side 213a of stall door 211. For example, in this figure, arm member 103d is against side 203b, arm member 103c is against side 213b, arm member 103a is against side 213a (obscured from view), and arm member 103b is against side 203a (obscured from view).
To use portable door lock assembly 100, a user performs the following method:
The user rotates one or more arm members of foundation member 101b (e.g., arm members 103c and 103d) such that the one or more arm members are at an angle relative to axis of 213 of track member 107. Optionally, the user rotates one or more arm members associated with track member 107 such that the one or more arm members are at a second angle relative to axis 213 of track member 107.
The user then positions portable lock assembly 100 between stall door 211 and stall wall 201, wherein stall door 211 and stall wall 201 are located between the one or more arm members of foundation member 101b and the one or more arm members associated with track member 107 (e.g., arm members 103a and 103b, or stop 115). The user either positions portable lock assembly 100 by translating portable door lock assembly 100 between stall wall 201 and stall door 211 from end 205 and end 215 of stall wall 201 and stall door 211 respectively, or from end 207 and 217 of stall wall 201 and stall door 211. The user then translates foundation member 101b along track member 107 towards the one or more arms associated with track member 107. For example, the user translates foundation member 101b towards foundation member 101a. In another example, the user translates foundation member 101b towards stop 115. Lastly, the user locks foundation member 101b with respect to track member 107. The user locks foundation member 101b with respect to track member 107 by engaging one or more latches (e.g., latches 105a and 105b) with a corresponding one or more recesses of track member 107 (e.g., recess 111a and 111b), wherein the one or more latches are spring biased to engage with the one or more recesses. In this position, portable door lock assembly 100 restricts stall door 211 from pivoting away from stall wall 201.
To remove portable lock assembly 100 from stall wall 201 and stall door 211, the user unlocks foundation member 101b with respect to track member 107. The user unlocks foundation member 101b with respect to track member 107 by disengaging one or more latch members from the corresponding one or more recesses of track member 107. For example, the user compresses the one or more latches against the spring of the one or more latches to disengage the one or more latches from the corresponding one or more recesses. The user then translates foundation member 101b along track member 107 away from the one or more arm members associated with track member 107. The user then removes portable lock assembly 100 from stall wall 201 and stall door 211. For example, the user removes portable lock assembly 100 by translating portable lock assembly 100 off either ends 205 and 215 or off ends 207 and 217. Lastly, the user rotates the one or more arm members of foundation member 101b such that the one or more arm members are parallel to track member 107. Optionally, the user rotates the one or more arm members associated with track member 107 such that the one or more arm member associated with track member 107 are parallel to track member 107.
