Abstract
Description
Technical Field
[0001] This invention relates to a limiting device and a lock box. Background Technology
[0002] Locks are widely used to secure living or working spaces and to prevent intentional theft and accidental removal of items. However, it is common for users to lose or discard their keys, rendering the locks unusable and resulting in additional expenses and inconvenience such as needing a locksmith or having the locks damaged. Therefore, it has been suggested to use lockboxes to store keys to avoid these situations.
[0003] On the other hand, when people go out for leisure, they still need to prevent theft of items they carry, such as hotel room keys and cards, and lock boxes may be used in this case.
[0004] However, existing lock boxes require unlocking before opening or closing, which is inconvenient and there is still room for improvement. Utility Model Content
[0005] The purpose of this invention is to provide a limiting device with better ease of use.
[0006] Another objective of this invention is to provide a lock box with better ease of use.
[0007] The present invention discloses a limiting device disposed on a sheet having a first surface and a second surface located on opposite sides. The limiting device includes an engaging member, a driving member, and a locking device. The engaging member is disposed on one side of the first surface of the sheet and is movable outward or inward along a first direction. The driving member passes through the sheet and includes a driving portion and an operating portion respectively exposed on the first and second surfaces. The driving portion is movably connected to the engaging member and is movable along the first direction, driving the engaging member to move inward along the first direction towards the first surface. The locking device is disposed on one side of the first surface of the sheet, and when the locking device is in a locked state, it restricts the movement of the driving member.
[0008] In this novel embodiment, the limiting device further includes an elastic unit disposed between the engaging member and the driving member, the elastic unit pushing the engaging member to move outward from the first surface.
[0009] In this embodiment of the invention, the engaging member includes an engaging end, and a guide unit is provided on the side of the engaging end opposite to the first surface.
[0010] In this novel embodiment, the guiding unit is an inclined surface whose height gradually decreases towards the outside of the first surface.
[0011] In an embodiment of this invention, the sheet has an operating hole through which the operating part passes.
[0012] In this embodiment of the invention, the engaging component has a slot, and the driving part has a connecting unit. The connecting unit is movably disposed in the slot, and the driving part can move inward along the first direction toward the interior of the first surface until the connecting unit abuts against the end of the slot facing the interior of the first surface, thereby driving the engaging component to move inward along the first direction toward the interior of the first surface.
[0013] In this embodiment of the invention, the lock is a combination lock, and multiple buttons of the combination lock pass through the sheet from the first side and are exposed on the second side.
[0014] The novel lock box includes a box body, a sheet, and a limiting device. The box body includes a box body opening and an interior accommodating space. The sheet has a first side and a second side located on opposite sides, is pivotally connected to one side of the box body opening, and can close the box body opening to seal the accommodating space.
[0015] In this embodiment of the invention, when the sheet covers the opening of the box, the locking member can be moved to the locking position to prevent the sheet from being lifted out of the opening of the box.
[0016] In this embodiment of the invention, when the lock is in the unlocked state, the driving member can move along the first direction and drive the engaging member to move inward along the first direction to leave the engaging position, thereby releasing the restriction on the sheet being lifted from the opening of the box.

[0053] The following detailed description, along with accompanying drawings, illustrates embodiments of the connection component disclosed herein. Those skilled in the art can understand the advantages and effects of this invention from the content disclosed in this specification. However, the following disclosure is not intended to limit the scope of protection of this invention. Without departing from the spirit of the invention, those skilled in the art can implement this invention in other different embodiments based on different viewpoints and applications. In the drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. Throughout the specification, the same reference numerals denote 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 may be directly on or connected to the other element, or an intermediate element may also be present. Conversely, when an element is referred to as being "directly on" or "directly connected" to another element, no intermediate element is present. As used herein, "connection" can refer to a physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" may refer to the presence of other elements between two elements.
[0054] It should be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, the “first element,” “component,” “region,” “layer,” or “part” discussed below may be referred to as a second element, component, region, layer, or part without departing from the teachings of this document.
[0055] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being “down” to other elements will be oriented “up” to other elements. Thus, the exemplary term “down” can include both “down” and “up” orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being “below” or “under” other elements will be oriented “above” other elements. Thus, the exemplary term “below” or “under” can include both “up” and “down” orientations.
[0056] As used herein, “about,” “approximately,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” or “substantially” herein may be chosen based on the optical, etched, or other properties to select a more acceptable range of deviations or standard deviations, and may not require a single standard deviation to apply to all properties.
[0057] like Figures 1 to 3 The embodiment shown illustrates that the lock box 900 of this novel invention includes a box body 100, a sheet 200, and a limiting device 300. For example... Figure 2 In the illustrated embodiment, the box 100 includes a box opening 110, and the interior of the box 100 has an accommodating space 120. The accommodating space 120 can be used to store items that need to be secured, such as keys, cards, mobile phones, watches, jewelry, and identification documents. The sheet 200 has a first surface 210 and a second surface 220 located on opposite sides, and is pivotally connected to one side 111 of the box opening 110, and can close the box opening 110 to seal the accommodating space 120. Viewed from different angles, the sheet 200 and one side 111 of the box 100 are pivotally connected by, for example, a pivot 230, and the sheet 200 can be rotated relative to the box 100 to open or close. In this embodiment, the box 100 is a cuboid; however, in different embodiments, the box 100 can be different shapes, such as a cube, cylinder, or disc, and the shapes of the box opening 110 and the sheet 200 can also vary according to aesthetic or functional requirements.
[0058] like Figure 3 In the illustrated embodiment, the limiting device 300 is disposed on the sheet 200 and includes a locking member 310, a driving member 320, and a lock 330. The locking member 310 is disposed on one side of the first surface 210 of the sheet 200 and can move outward or inward along the first direction 410. Viewed from different angles, in one embodiment, the locking member 310 can move upward or downward along the first direction 410. However, in different embodiments, the direction of movement of the locking member 310 can be varied as needed.
[0059] like Figures 1 to 3In the illustrated embodiment, the driving member 320 passes through the sheet 200 and includes a driving portion 321 and an operating portion 322 exposed on the first surface 210 and the second surface 220, respectively. The sheet 200 may have an operating hole 240 through which the operating portion 322 passes. The driving portion 321 is movably connected to the engaging member 310 and is movable along a first direction 410, driving the engaging member 310 to move along the first direction 410 into the first surface 210. More specifically, the engaging member 310 has a slot 311, and the driving portion 321 has a connecting unit 321A movably disposed within the slot 311. The drive unit 321 can move along the first direction 410 into the interior of the first surface 210 until the connecting unit 321A and the end 311A of the slot 311 facing the interior of the first surface 210 abut against each other, and drive the engaging member 310 to move along the first direction 410 into the interior of the first surface 210, that is, to move downward.
[0060] like Figures 1 to 3 In the illustrated embodiment, the lock 330 is disposed on one side of the first surface 210 of the sheet 200, and when the lock 330 is in the locked state, it restricts the movement of the drive member 320. More specifically, in one embodiment, the lock 330 is a combination lock, and a plurality of buttons 331 of the combination lock pass through the first surface 210 and protrude from the sheet 200 onto the second surface 220 for user operation. Wherein, as Figure 3 In the illustrated embodiment, the lock 330 has a lever 332 that abuts against the lower edge of the drive unit 321. Therefore, when the lock 330 is in the locked state, the displacement of the lever 332 is restricted, thereby restricting the downward movement of the drive unit 320.
[0061] The following further explains the operation mode of this novel invention.
[0062] like Figure 4 In the illustrated embodiment, the limiting device 300 further includes an elastic unit 340 disposed between the engaging member 310 and the driving member 320, more specifically located within the slot 311. Because the rod 332 is acted upon by the elastic element inside the lock 330, it abuts upward against the lower edge of the driving part 321, thus pushing the driving part 321 upward toward the outside of the first surface 210. With the driving part 321 as support, the elastic unit 340 also pushes the engaging member 310 upward toward the outside of the first surface 210, and can move to the engaging position 500. Figure 5 In the embodiment shown, when the sheet 200 is open relative to the housing 100 and the operating part 322 is not under force, the engaging member 310 is in the engaging position 500.
[0063] like Figure 6In the embodiment shown, when the sheet 200 is rotated relative to the housing 100 to near closing, the engaging member 310 engages with the housing opening 110 (see [reference]). Figure 5 The flange 112 contacts and moves downward toward the interior of the first surface 210, moving away as if... Figure 5 The engagement position 500 is shown. More specifically, the engagement member 310 includes an engagement end 312, and a guide unit 312A is provided on the other side of the engagement end 312 opposite to the first surface 210. The guide unit 312A is an inclined surface whose height gradually decreases towards the outside of the first surface 210. Accordingly, when the sheet 200 rotates relative to the housing 100 until the engagement member 310 contacts the flange 112, a downward force towards the inside of the first surface 210 can be generated through the guide unit 312A to overcome the elastic unit 340 (see...). Figure 4 The thrust of the engagement element 310 causes it to move downwards and inwards towards the first surface 210 to pass over the flange 112. Then, as... Figure 7 In the embodiment shown, when sheet 200 covers the opening 110 of the box (see...) Figure 5 The engaging part 310 can be moved back to the engaging position 500, and by abutting against the flange 112, it restricts the sheet 200 from being lifted from the box opening 110.
[0064] Furthermore, the drive unit 321 is closer to the interior of the first surface 210 than the engaging member 310. During the rotation of the sheet 200 relative to the housing 100 until it closes to the opening of the housing, it will not contact the flange 112. That is, the drive unit 321 and the drive member 320 themselves will not interfere with the rotation of the sheet 200 relative to the housing 100. This process also does not involve the lock 330, which restricts the downward movement of the drive member 320. In other words, whether the lock 330 is locked or unlocked, it does not affect the process of the sheet 200 rotating relative to the housing 100 until it closes to the opening of the housing and is restricted from being opened by the engaging member 310. Therefore, the user does not need to unlock the lock 330 before closing the sheet 200, making it more convenient to use.
[0065] However, as Figure 7 In the illustrated embodiment, when the operating part 322 is subjected to an external force downward toward the interior of the second surface 220, and the lock 330 is in the locked state, the displacement of the lever 332 is restricted, thereby restricting the downward movement of the drive member 320. Accordingly, the engaging member 310 is held in the engaging position 500, and by abutting against the flange 112, the sheet 200 is restricted from moving out of the housing opening 110 (see...). Figure 5 (Open it.) On the contrary, as... Figure 8 In the embodiment shown, when the operating part 322 is subjected to an external force downward toward the interior of the second surface 220, and the lock 330 is in the unlocked state, the lever 332 (see Figure 7The movable part can enter the lock 330 without restricting the downward movement of the drive member 320. Accordingly, the drive member 320 can move along the first direction 410, and drive the engaging member 310 downward along the first direction 410 toward the interior of the first surface 210 to leave the engaging position 500, thus releasing the sheet 200 from the opening 110 of the box (see...). Figure 5 The restrictions were lifted. Then, as... Figure 9 As shown, the sheet 200 can be opened from the box opening 110, allowing the user to place or remove objects in the receiving space 120.
[0066] This invention has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this invention. It must be noted that the disclosed embodiments do not limit the scope of this invention. Conversely, modifications and equivalent settings within the spirit and scope of the claims are all included within the scope of this invention.
