Abstract
Description
Technical Field
[0001] The invention relates to a limiting device, in particular to a device for limiting the relative position between a cabinet door and a cabinet body. Background Art
[0002] In public places such as stores, campuses, stations, and gyms, lockers are installed to display or temporarily store items in showcases and lockers to prevent intentional theft or accidental misappropriation. For the sake of aesthetics and ease of operation, locks with a tongue and a lock core are commonly used. The tongue is rotated to engage the cabinet body and the cabinet door. When the lock core is in a locked state, the lock core restricts the rotation of the tongue. However, the mechanical strength of a single tongue is weak, which may cause the cabinet door to be forced open by external force. Summary of the invention
[0003] The present invention provides a limiting device, which can limit the position of an object stably and has a relatively stable fixing effect and better strength.
[0004] The limiting device of the present invention includes a support member and a limiting member. The limiting member is pivotally connected to the support member. The limiting member includes an operating unit, a first limiting unit arranged on one side of the limiting member, and a second limiting unit arranged on the same side of the limiting member. The limiting device is used in conjunction with an article having a limiting hole. When the operating unit is in the first state, the second limiting unit and the limiting hole are no longer misaligned, and the first limiting unit can move from a locked position to an unlocked position. When the first limiting unit moves from the locked position to the unlocked position, the second limiting unit moves from the unlocked position to a fully unlocked position.
[0005] In an embodiment of the present invention, when the second limiting unit moves from the unlocking position to the fully unlocking position, at least a portion of the second limiting unit enters or passes through the limiting hole.
[0006] In an embodiment of the present invention, the support member is integrally formed with the object.
[0007] In an embodiment of the present invention, the support member is embedded in the object.
[0008] In an embodiment of the present invention, when the operating unit is in the first state, the second limiting unit can rotate to release the misalignment with the limiting hole, and the rotation direction of the second limiting unit is different from the rotation direction of the limiting member.
[0009] In an embodiment of the present invention, the limiting member further includes a shell member, and the shell member includes a first shell member surface and a second shell member surface located on opposite sides. The operating unit is disposed in the shell member and has an operating portion exposed on the first shell member surface. The first limiting unit is fixed to the second shell member surface, and includes a fixing portion extending outwardly from the second shell member surface, and an extending portion extending to one side from one end of the fixing portion away from the second shell member surface. The second limiting unit is disposed on the second shell member surface, and includes a rod member and a clamping portion. The rod member is pivotally connected to the operating unit and extends outwardly from the second shell member surface. The clamping portion extends to one side from one end of the rod member away from the second shell member surface. When the operating unit is in the second state, the extending portion and the clamping portion are misaligned. When the operating unit is in the first state, the rod member can rotate relative to the central axis of the rod member to drive the clamping portion to rotate.
[0010] In an embodiment of the present invention, the extension portion faces downward, and the stopper hole extends in a vertical direction. When the operating unit is in the first state, the engaging portion is horizontal, and the stopper is restricted from rotating to drive the first stopper unit and the second stopper unit to pass through the stopper hole. When the operating unit is in the first state, the rod can rotate relative to the central axis of the rod to drive the engaging portion to rotate upward, so that the stopper can rotate to drive the first stopper unit and the second stopper unit to pass through the stopper hole.
[0011] In an embodiment of the present invention, the operating unit is a key lock and is used in conjunction with a key. The user can operate the key to put the operating unit in the first state, while rotating the rod to drive the engaging portion to rotate, and applying force to the key to rotate the limiting member.
[0012] In an embodiment of the present invention, the operating unit is a combination lock, and the limiting member further includes a knob that can drive the rod. The user can operate the operating unit to be in the first state, and operate the knob to rotate the rod to drive the locking portion to rotate, and apply force to the limiting member to rotate the limiting member.
[0013] In an embodiment of the present invention, the limiting device further includes a shielding piece pivotally connected to the supporting member, and the shielding limiting member is exposed from one side of the supporting member. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following is a specific embodiment and a drawing to illustrate the embodiment of the connection assembly disclosed in the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. However, the content disclosed below is not intended to limit the scope of protection of the present invention. Without deviating from the principle of the spirit of the present invention, those skilled in the art can implement the present invention with other different embodiments based on different viewpoints and applications. In the accompanying drawings, for the sake of clarity, the thickness of the layer, film, panel, region, etc. is magnified. Throughout the specification, the same reference numerals represent the same elements. It should be understood that when an element such as a layer, film, region or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to another element, or an intermediate element can also exist. On the contrary, when an element is referred to as "directly on" or "directly connected to" another element, there is no intermediate element. As used herein, "connection" can refer to physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" can be the presence of other elements between two elements.
[0056] It should be understood that although the terms "first", "second", "third", etc. can be used to describe various elements, components, regions, layers and / or parts in this article, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, the "first element", "component", "region", "layer" or "part" discussed below can be referred to as a second element, component, region, layer or part without departing from the teachings of this article.
[0057] In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship of one element to another element, as shown in the figures. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if the device in one figure is turned over, the element described as being on the "lower" side of the other elements will be oriented on the "upper" side of the other elements. Therefore, the exemplary term "lower" can include both "lower" and "upper" orientations, depending on the specific orientation of the figure. Similarly, if the device in one figure is turned over, the element described as being "below" or "below" other elements will be oriented as being "above" other elements. Therefore, the exemplary term "below" or "below" can include both above and below orientations.
[0058] As used herein, "about", "approximately", or "substantially" includes the stated value and the average value within an acceptable deviation range of the particular value determined by one of ordinary skill in the art, taking into account the measurement in question and the particular amount of error associated with the measurement (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, as used herein, "about", "approximately", or "substantially" can select a more acceptable deviation range or standard deviation depending on the optical property, etching property or other property, and can apply to all properties without a single standard deviation.
[0059] The limiting device of the present invention can be used in conjunction with an object having a limiting hole to limit the relative position of two objects. More specifically, Figure 1A and Figure 1B In the embodiment shown, the limiting device 800 can be used to limit the relative positions of the cabinet door 910 and the cabinet body 920 of the cabinet 900. Figure 1A In the embodiment shown, the limiting device 800 can be an independent module and embedded in the cabinet door 910. Figure 1B In the illustrated embodiment, part of the cabinet door 910 can be used as a component of the limiting device 800 , that is, the limiting device 800 and the cabinet door 910 are co-structured.
[0060] like FIG. 2A to FIG. 2DIn the illustrated embodiment, the limiting device 800 includes a support member 100 and a limiting member 200. The limiting member 200 is pivotally connected to the support member 100, for example, by a pivot 291. The limiting member 200 includes an operating unit 230, a first limiting unit 210 disposed on one side of the limiting member 200, and a second limiting unit 220 disposed on the same side of the limiting member 200. The limiting device 800 is used in conjunction with a sheet 920' having a limiting hole 929, wherein the sheet 920' may be a part of a cabinet body 920 of a cabinet 900 (see FIG. 1). When the operating unit 230 is in the first state, the second limiting unit 220 is released from the limiting hole, and the first limiting unit 210 can move from the locked position to the unlocked position. When the first limiting unit 210 moves from the locked position to the unlocked position, the second limiting unit 220 moves from the unlocked position to the fully unlocked position. When the operating unit 230 is in the second state, the movement of the first limiting unit 210 is restricted.
[0061] Specifically, if Figure 2A and Figure 2B In the embodiment shown, when the operating unit 230 is in the second state, the first limiting unit 210 and the second limiting unit 220 are staggered, and their orthographic projections on the YZ plane are perpendicular to each other; Figure 2C and Figure 2D In the embodiment shown, when the operating unit 230 is in the first state, the second limiting unit 220 can rotate, for example, parallel to the YZ plane, to eliminate the misalignment with the limiting hole 929. The X axis, Y axis, and Z axis are orthogonal. The operating unit 230 is preferably, but not limited to, a lock body such as a key lock or a combination lock, and the first state and the second state are an unlocked state and a locked state, respectively.
[0062] More specifically, if FIG. 2A to FIG. 2DIn the embodiment shown, the limiting member 200 further includes a shell 240, the shell 240 includes a first shell surface 241 and a second shell surface 242 located on opposite sides, wherein the operating unit 230 is disposed in the shell 240 and has an operating portion 231 exposed on the first shell surface 241. In the embodiment where the operating unit 230 is a key lock, the operating portion 231 is an end surface having a key hole. The first limiting unit 210 is fixed to the second shell surface 242, and includes a fixing portion 211 and an extending portion 212. The fixing portion 211 extends outward from the second shell surface 242, for example, extending in a direction parallel to the X axis, that is, away from the first shell surface 241. The extending portion 212 extends from one end of the fixing portion 211 away from the second shell surface 242 to one side, for example, extending in a direction parallel to the YZ plane. The second limiting unit 220 is disposed on the second shell surface 242, and includes a rod 221 and a clamping portion 222. The rod 221 is pivotally connected to the operating unit 230, for example, extending outwardly from the second surface 242 of the shell in a direction parallel to the X axis. The engaging portion 222 extends from one end of the rod 221 away from the second surface 242 of the shell to one side, for example, extending in a direction parallel to the YZ plane. The support member 100 includes a first surface 110 and a second surface 120 of the support member located on opposite sides of the support member 100, and a hollow portion 140 penetrating from the first surface 110 of the support member to the second surface 120 of the support member. The shell 240 is disposed in the hollow portion 140. The extension portion 212 and the engaging portion 222 are located on the outside of the second surface 120 of the support member.
[0063] like Figure 2B In the embodiment shown, when the operating unit 230 is in the second state, the extension portion 212 and the engaging portion 222 are offset, for example, their projections on the YZ plane are perpendicular to each other. Figure 2D In the embodiment shown, when the operating unit 230 is in the first state, the rod 221 can rotate relative to the central axis 221a of the rod 221 to drive the engaging portion 222 to rotate, for example, to rotate parallel to the YZ plane. From different angles, the engaging portion 222 and the rod 221 have a vertical angle. However, in different embodiments, the angle between the engaging portion 222 and the rod 221 can be changed for the needs of manufacturing or use. For example, the angle between the engaging portion 222 and the rod 221 can be less than 90° to form a point contact, thereby reducing the friction between the engaging portion 222 and the sheet 920' when the engaging portion 222 rotates.
[0064] Furthermore, if FIG. 2A to FIG. 2DIn the embodiment shown, the limiting device 800 is used in combination with a sheet 920' having a limiting hole 929, wherein the sheet 920' may be a part of a cabinet body 920 of a cabinet 900 (see FIG. 1), and the support member 100 may be a part of a cabinet door 910 of the cabinet 900, that is, the limiting device 800 and the cabinet door 910 are co-structured. In other words, the support member 100 and the cabinet door 910 of the cabinet 900 are made into one piece. In this embodiment, the extension portion 212 faces downward, and the limiting hole 929 extends in a vertical direction. When the operating unit 230 is in a second state such as a locked state, the engaging portion 222 is, for example, horizontal and staggered with the limiting hole 929. Since the length L222 of the engaging portion 222 is greater than the width W929 of the limiting hole 929, the limiting member 200 can be limited to rotate to drive the first limiting unit 210 and the second limiting unit 220 to pass through the limiting hole 929. From different angles, the rotation of the stopper 200 is limited by the horizontal state of the engaging portion 222, which can actually achieve the effect of limiting the stopper 200 away from the sheet 920' by the extension portion 212 and the engaging portion 222 at the same time, thereby limiting the relative position of the cabinet body and the cabinet door 910. Compared with the conventional cabinet door switch that only uses a single tongue to engage the cabinet body and the cabinet door, the stopper 800 of the present invention limits the relative position of the cabinet body 920 and the cabinet door 910 by the extension portion 212 and the engaging portion 222 together, which is not only more stable, but also has better mechanical strength by using the fixed extension portion 212, reducing the chance of the cabinet door being forced open by external force.
[0065] like Figure 2D In the embodiment shown, when the operating unit 230 is in the first state, such as the unlocked state, the rod 221 can rotate relative to the central axis of the rod 221 to drive the engaging portion 222 to rotate upward, so that the limiting member 200 rotates to drive the first limiting unit 210 and the second limiting unit 220 to pass through the limiting hole 929. When the operating unit 230 is in the second state, the movement of the first limiting unit 210 is restricted. More specifically, as FIG. 3A to FIG. 3C In the embodiment shown, the operating unit 230 is a key lock and is used in conjunction with the key 400. The user can insert the key 400 into the lock hole 234 and then rotate the operating unit 230 to lock the operating unit 230. FIG. 4A to FIG. 4C The first state shown is an unlocked state, and the rod 221 is rotated to drive the engaging portion 222 to rotate parallel to the YZ plane. Since the engaging portion 222 rotates to be offset from the limiting hole 929, that is, the second limiting unit 220 is no longer offset from the limiting hole 929, it can be as shown in FIG. Figure 5A and Figure 5B As shown, the key 400 is pressed downwardly, so that the limiting member 200 can rotate parallel to the XY plane to drive the first limiting unit 210 and the second limiting unit 220 to pass through the limiting hole 929. Further, the first limiting unit 210 can be self-contained, for example Figure 4C The locked position 710 shown is moved to, for example, Figure 5B The first limiting unit 210 moves from the locked position 710 to the unlocked position 720, and the second limiting unit 220 moves from the unlocked position 730 to the fully unlocked position 740. When the second limiting unit 220 moves from the unlocked position 730 to the fully unlocked position 740, at least a portion of the second limiting unit 220 enters or passes through the limiting hole 929. This releases the restriction on the movement of the cabinet door relative to the cabinet body, so as to further Fig. 6A and Figure 6B As shown, the limiting device is moved away from the sheet 920', that is, the cabinet door is pulled away from the cabinet body. Among them, the key 400 preferably has a long handle, which can facilitate the user to use torque to increase the force. In the above embodiment, the long axis direction of the limiting hole 929 is parallel to the Y axis, that is, the limiting hole 929 extends up and down, so the engaging portion 222 can be staggered with the limiting hole 929 when it is rotated to the upward direction. In different embodiments, the long axis direction of the limiting hole 929 is not limited to being parallel to the Y axis, that is, the limiting hole 929 can extend obliquely relative to the vertical, and when the engaging portion 222 is rotated until its long axis direction is parallel to the long axis direction of the limiting hole 929, it can be staggered with the limiting hole 929.
[0066] The operating unit 230 may be a lock other than a key lock, such as a combination lock, a fingerprint lock, or a sensor lock. Figure 7 In the illustrated embodiment, the operating unit 230' is a combination lock, and the limiting member 200 further includes a knob 238 that can drive the rod. The user can operate the operating unit 230' to be in a first state such as an unlocked state, and operate the knob 238 to rotate the rod to drive the engaging portion to rotate parallel to the YZ plane, and apply force to the limiting member 200 so that the limiting member 200 can rotate parallel to the XY plane.
[0067] like Figure 8 In the illustrated embodiment, the position limiting device 800 may include a shielding sheet 500 pivotally connected to the support member 100, for shielding the position limiting member 200 from being exposed from one side of the support member 100. Thus, the protection and confidentiality of the position limiting member 200 can be enhanced.
