As explained above, the second end 72 of the center frame member 38 is connected to the lower support member 44.

[0048] Return to reference locking mechanism 10, such as Figures 4 to 9 As shown, a top cover 54 is fixed to a housing 50, and a button 52 is held therein and is capable of linear movement therein. A biasing member 56 biases the button 52 away from the top cover 54. The top cover 54 has a plurality of posts 96 and a push bottom 52, the plurality of posts 96 extending into the housing 50, and the push bottom having a plurality of mating openings 98. The posts 96 pass through the openings 98 in the button 52 to allow the button 52 to be linearly positioned across the posts 96.

[0049] like Figures 6 to 9As shown, in one embodiment, the central frame member 38 has a hole 100, and the bracket 58 is fixedly positioned within the hole 100 of the central frame member 38. In one embodiment, the bracket 58 has a first end 102 and a second end 104. A lip 106 is provided at the first end 102 of the bracket 58, and the lip 106 is located on top of the central frame member 38. The bracket 58 has a cavity 108 between the first end 102 and the second end 104 to slidably receive the cam member 60. The bracket 58 also has an opening 110 for receiving a locking pin 62, and has a biasing member 94 for biasing the locking pin 62 through the hole 112 in the cam member 60 and the central frame member 38. Furthermore, the biasing member 94 applies a downward force on the cam member 60. For assembly purposes, when the cam member 60, locking pin 62, biasing member 94, and biasing member 64 are in the appropriate positions within the bracket 58, the bracket 58 is inserted into the hole 100 at the first end 70 of the center frame member 38. The first end 70 of the center frame member 38 then fits into the lower opening 68 of the housing 50. Fasteners 114 (such as rivets) are used, for example, to secure the center frame member 38 (which has the bracket 58 and cam member 60) to the housing 50, as... Figure 6 and Figure 8 As shown.

[0050] In one embodiment, the cam member 60 has a first end 120, a second end 122, a connecting member 124 connecting the first end 120 and the second end 122, a first opening 126 through the connecting member 124, and a second opening 128 adjacent to the second end 122. The first opening 126 is preferably a slot that allows a fastener 114 to extend through the cam member 60, but allows the cam member 60 to be linearly transverse within the cavity 108 of the bracket 58. In one embodiment, the second end 122 of the cam member 60 has a cam surface 130, such as an angled surface, that engages a locking pin 62. The second opening 128 allows the locking pin 62 to extend through the cam member 60 and through a hole 112 in the central frame member 38 to engage the slider member 46.

[0051] like Figures 4 to 7 As shown, in one embodiment, the locking pin 62 has a first end 132, a second end 134, and two protrusions 136 extending from the locking pin 62 between the first end 132 and the second end 134. The protrusions 136 engage the cam surface 130 of the cam member 60. The first end 132 of the locking pin 62 has an inclined surface 138. The second end 134 of the locking pin 62 engages the opening 110 of the bracket 58 and the biasing member 64 to bias the locking pin 62 toward the hole 112 in the central frame member 38.

[0052] In one embodiment, such as Figure 5 , Figure 6 and Figure 8 As shown, the button component 52 has an extension 140 that engages the first end 120 of the cam component 60 through an opening 142 in the housing 50 (see Figure 1). Figure 4 ).

[0053] refer to Figure 1 , Figure 6 ,as well as Figure 7 When the carriage 12 is in the unfolded or in use state, the slider member 46 is in its upward position. When the button 52 is not actuated, the biasing member 94 operates to push the button 52 away from the top cover 54. In this position, the cam member 60 is in its first or lowered position, and the locking pin 62 is in its biased position, such that the first end 132 of the locking pin 62 extends through the second opening 128 in the cam member 60, the hole 112 in the central frame member 38, and into the receiver 80 in the slider member 46 to lock the slider member 46 in place.

[0054] To allow the carriages to be folded 12-fold as follows Figure 10 The folding orientation shown actuates the button 52 by pressing it against the biasing force of the biasing member 94 toward the top cover 54. When the button 52 moves upward, the extension 140 of the button 52 engages the first end 120 of the cam member 60, causing the cam member 60 within the cavity 108 of the bracket 58 to change from a lowered position or a first position to an upper position or a second position, as shown. Figure 8 and Figure 9 As shown. When the cam member 60 changes from the first position to the second position, the cam surface 130 of the cam member 60 engages the protrusion 136 of the locking pin 62, causing the locking pin 62 to move axially toward the opening 110 in the bracket 58, so that the first end 132 of the locking pin 62 disengages from the receiver 80 of the slider member 46, thereby unlocking the slider member 46. At this time, the slider member 46 can move linearly on the central frame member 38 to allow the frame to collapse into a folded state.

Furthermore, the terms “first,” “second,” “third,” and “fourth” as used herein are for illustrative purposes only and are not intended to limit the embodiments in any way. Additionally, the term “plural” as used herein refers to any number greater than one (separately or in combination as needed) up to an infinite value. Furthermore, the term “having” as used herein is used in an open-ended manner in this disclosure and claims.

[0059] As used herein, the phrase “at least one of…” preceding a list of items (separated by the terms “and” or “or”) modifies the entire list as a whole, not each member of the list (i.e., each item). The phrase “at least one of…” does not require the selection of at least one item; rather, it allows for the following meanings: at least one item from any of the items, and / or at least one combination of any combination of the items, and / or at least one of each of the items. For example, the phrases “at least one of A, B, and C” or “at least one of A, B, or C” respectively refer to: only A, only B, or only C; any combination of A, B, and C; and / or at least one of each of A, B, and C.

[0060] With regard to the use of terms such as “comprising” or “having” in the specification or claims, such terms are intended to be inclusive (similar to the interpretation of the terms “comprising” or “including”), as “comprising” is interpreted as a transitional term in the claims. Phrases such as aspect, that aspect, on the other hand, some aspects, one or more aspects, embodiment, that embodiment, another embodiment, some embodiments, one or more embodiments, example, that embodiment, another embodiment, some embodiments, one or more embodiments, configuration, that configuration, another configuration, some configurations, one or more configurations, subject matter, disclosure, this disclosure, other variations, etc., are for convenience only, and such phrases do not imply that the disclosure associated with such phrase(s) is essential to the subject matter, or that such disclosure applies to all configurations of the subject matter. The disclosure associated with such phrase(s) may apply to all configurations or one or more configurations. The disclosure associated with such phrase(s) may provide one or more examples. Phrases such as “aspect” or “some aspects” may refer to one or more aspects, and vice versa, and similarly, this also applies to other foregoing phrases.

[0061] Unless specifically stated otherwise, references to singular elements are not intended to mean "one and only one," but rather "one or more." The term "some" refers to one or more. Underlined and / or italicized headings and subheadings are used merely for convenience and do not limit the subject matter, nor are they referred to in connection with the interpretation of the description of the subject matter. Relational terms such as "first" and "second" may be used to distinguish one entity or action from another without necessarily requiring or implying any actual such relationship or order between these entities or actions. By reference, all structural and functional equivalents of elements in various configurations described herein that are known or will be known hereafter by one of ordinary skill in the art are expressly incorporated herein and are intended to be covered by the subject matter. Furthermore, nothing disclosed herein is intended to be offered to the public, whether or not such disclosures are expressly stated in the foregoing description. Unless the element is explicitly stated using the phrase "unit for..." or, in the case of a method claim, the element is stated using the phrase "step for...", no claim element is to be interpreted in accordance with the provisions of paragraph 6 of 35 U.SC § 112.

[0062] While this specification includes numerous details, these details should not be construed as limiting the scope of the claims, but rather as descriptions of specific embodiments of the subject matter. Some features described in the context of a single embodiment may also be implemented as a combination in a single embodiment. Conversely, various features described in the context of a single embodiment may also be implemented individually or as any suitable sub-combination in multiple embodiments. Furthermore, while features may be described above as functioning in certain combinations and even initially claimed in this way, in some cases, one or more features from the claimed combination may be removed from the combination, and the claimed combination may be directed to a sub-combination or a variation thereof.

[0063] Therefore, the title of the invention, background art, description of the drawings, abstract, and drawings are incorporated into this disclosure and are provided as illustrative examples of this disclosure, not as limiting descriptions. They are submitted with the understanding that they will not be used to limit the scope or meaning of the claims. Furthermore, in the detailed description, it will be apparent that the description provides illustrative examples and that various features are grouped together in various embodiments for the purpose of simplifying this disclosure. The approach of this disclosure should not be construed as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. On the contrary, as reflected in the claims, the inventive subject matter lies in fewer than all features in the configuration or operation of a single disclosure. Therefore, the claims are incorporated into the detailed description, wherein each claim is independently claimed as a separate subject matter.

[0064] It should be understood that this disclosure may be embodied in other specific forms without departing from the spirit or central characteristics of this disclosure. Therefore, these examples and embodiments are to be considered illustrative rather than restrictive in all respects, and the claims are not limited to the details given herein. Thus, while specific embodiments have been shown and described, many modifications may be contemplated without obvious departure from the spirit of this disclosure, and the scope of protection is limited only by the scope of the appended claims.

[0065] Furthermore, the claims are not intended to be limited to the aspects described herein, but rather to conform to the full scope consistent with the language claims and to cover all legal equivalents. Nevertheless, none of the claims are intended to include subject matter that does not meet the requirements of applicable patent law, nor should the claims be interpreted in this manner.
