Abstract
Description
- This application claims the priority benefit of U.S. provisional application Ser. No. 62/717,915, filed on Aug. 13, 2018. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
- The application relates to a strap and a display device, and more particularly, the application relates to an adjustable strap and a head mounted display device featuring the adjustable strap.
- In recent years, applications of virtual reality (VR) become more and more popular. Generally, a user usually fixes a head mounted display (HMD) onto the head through a strap. In order to allow users to easily tighten and release the straps, it is observed that complicated mechanical design is adopted at present, and as such, a large number of parts are required, costs are raised, and assembly difficulty is increased. Therefore, how to fix a head mounted display device onto a user's head through a simple and convenient manner and reduce costs at the same time is an important issue.
- The application provides an adjustable strap which allows a user to make adjustment easily and quickly.
- An adjustable strap of the application includes a body, a sliding member, a limiting member, and an engaging member. Two opposite sides of the body are a slot section and a control section, and the slot section has a slot and an engaging portion. The slot extends in a length direction of the slot section. The engaging portion is located at lateral sides of the slot. The control section has a through hole. The body circles around to enable the slot section and the control section to overlap. The sliding member and the limiting member pass through the slot and the through hole for connection. The slot section and the control section are sandwiched between the sliding member and the limiting member. The engaging member and the control section pass through the slot for fixed connection, and the sliding member and the limiting member are configured to slide between a first end and a second end opposite to each other of the through hole. The first end is farther away from the engaging member fixedly connected to the control section than the second end. When the sliding member and the limiting member are at the first end, the limiting member restricts an engaging end of the engaging member to be away from the engaging portion, such that the slot section and the control section are relatively slidable freely. When the sliding member and the limiting member are at the second end, the limiting member releases restriction of the engaging end, such that the engaging end engages the engaging portion to restrict relative sliding between the slot section and the control section.
- A head mounted display device of the application includes a display portion and an adjustable strap. The adjustable strap is connected to the display portion. The adjustable strap includes a body, a sliding member, a limiting member, and an engaging member. Two opposite sides of the body are a slot section and a control section, and the slot section has a slot and an engaging portion. The slot extends in a length direction of the slot section. The engaging portion is located at lateral sides of the slot. The control section has a through hole. The body circles around to enable the slot section and the control section to overlap. The sliding member and the limiting member pass through the slot and the through hole for connection. The slot section and the control section are sandwiched between the sliding member and the limiting member. The engaging member and the control section pass through the slot for fixed connection, and the sliding member and the limiting member are configured to slide between a first end and a second end opposite to each other of the through hole. The first end is farther away from the engaging member fixedly connected to the control section than the second end. When the sliding member and the limiting member are at the first end, the limiting member restricts an engaging end of the engaging member to be away from the engaging portion, such that the slot section and the control section are relatively slidable freely. When the sliding member and the limiting member are at the second end, the limiting member releases restriction of the engaging end, such that the engaging end engages the engaging portion to restrict relative sliding between the slot section and the control section.
- To sum up, in the adjustable strap and the head mounted display device of the application, since the slot section and the control section are located at the two opposite sides of the body, the total number of parts of the application is accordingly reduced and costs are further lowered. In addition, as the through hole is formed on the control section and the sliding member and the limiting member can slide between the first end and the second end of the through hole, the engaging ends are further driven to be away from or propped against the engaging portion, so that the slot section and the control section are controlled to relatively slide, and the body is therefore adjusted. The structural design between the slot section and the control section allow the user only has to push the sliding member along the slot when using the adjustable strap provided by the application, and that adjustment and locking are completed at the same time, and convenient using experience is thus provided.

FIG. 1 illustrates a head mounted display device according to an embodiment of the invention.FIG. 2 is a schematic local view of an adjustable strap ofFIG. 1 .FIG. 3 is a schematic local view of relative sliding between a slot section and a control section ofFIG. 2 .FIG. 4 is a schematic local view of the adjustable strap ofFIG. 2 from another viewing angle. With reference toFIG. 1 toFIG. 4 , a head mounteddisplay device 10 of this embodiment includes adisplay portion 12 and anadjustable strap 100 connected to thedisplay portion 12. It is worth noting that theadjustable strap 100 of this embodiment may also be applied on a shoe, a safety helmet, a helmet, or other devices so that tightness can be conveniently adjusted. - In this embodiment, the
adjustable strap 100 includes abody 110, a slidingmember 120, a limitingmember 130, and an engagingmember 140. Two sides of thebody 110 are aslot section 111 and acontrol section 112, and thebody 110 circles around to enable a portion of theslot section 111 and a portion of thecontrol section 112 to overlap. For instance, theslot section 111 and thecontrol section 112 of thebody 110 are connected by a middle section (not labeled), and thedisplay portion 12 is connected to the middle section. Theslot section 111 has aslot 114 and an engagingportion 116. Theslot 114 extends in a length direction L of theslot section 111. The engagingportion 116 is located at lateral sides of theslot 114. In this embodiment, the engagingportion 116 is located at two lateral sides of theslot 114, but the engagingportion 116 may also be located only at one single lateral side of theslot 114, and the application is not limited thereto. Thecontrol section 112 has a through hole 115 (shown inFIG. 6A ). The slidingmember 120 and the limitingmember 130 pass through theslot 114 and the throughhole 115 for connection. Theslot section 111 and thecontrol section 112 are sandwiched between the slidingmember 120 and the limitingmember 130. The engagingmember 140 and thecontrol section 112 pass through theslot 114 for fixed connection. -
FIG. 5A is a schematic local view of engaging ends ofFIG. 2 being away from an engaging portion.FIG. 5B is a schematic local enlargement view ofFIG. 5A .FIG. 6A is a schematic local view of the engaging ends ofFIG. 5A engaging with the engaging portion.FIG. 6B is a schematic local enlargement view ofFIG. 6A . It is worth noting that in order to allow the drawings to be easily understood, the engagingportion 116 is omitted inFIG. 5B andFIG. 6B . With reference toFIG. 5A ,FIG. 5B ,FIG. 6A , andFIG. 6B , the limitingmember 130 includes a slidingportion 132 and a limitingportion 134 connected to the slidingportion 132. In this embodiment, it is the slidingportion 132 of the limitingmember 130 which passes through theslot 114 and the throughhole 115 to be connected to the slidingmember 120, but it may also be a portion of the slidingmember 120 which passes through theslot 114 and the throughhole 115 to be connected to the limitingmember 130, and the application is not limited thereto. Specifically, since a size of the throughhole 115 in the length direction L is slightly greater than that of the slidingportion 132, the slidingmember 120 and the limitingmember 130 may relatively side between afirst end 115 a and asecond end 115 b opposite to each other of the throughhole 115. Thefirst end 115 a is farther away from the engagingmember 140 fixedly connected to thecontrol section 112 than thesecond end 115 b. - As shown in
FIG. 5A andFIG. 5B , when the slidingmember 120 and the limitingmember 130 are at thefirst end 115 a, the limitingmember 130 restricts engaging ends 142 of the engagingmember 140 to be away from the engagingportion 116, such that theslot section 111 and thecontrol section 112 are relatively slidable freely, so that tightness applied by thebody 110 to the head of a user may be adjusted. As shown inFIG. 6A andFIG. 6B , when the slidingmember 120 and the limitingmember 130 are at thesecond end 115 b, the limitingportion 134 of the limitingmember 130 releases restriction of the engaging ends 142, such that the engaging ends 142 engages with the engagingportion 116 to restrict relative sliding between theslot section 111 and thecontrol section 112, and fixing is thereby achieved. -
FIG. 7 is a schematic local enlargement view of a tail end of the slot section ofFIG. 3 . It is worth noting that in order to allow the drawings to be easily understood,FIG. 7 illustrates only the components which are related to the structure of the engagingportion 116. With reference toFIG. 7 , in this embodiment, the engagingportion 116 is, for example, a rack, but the application is not intended to limit the type of the engagingportion 116. Specifically, the engagingportion 116 includes a plurality of triangular teeth T, and each of the triangular teeth T has a first inclined surface S1 and a second inclined surface S2. In each of the triangular teeth T, the second inclined surface S2 is closer to atail end 113 of theslot section 111 than the first inclined surface S1. An included angle A1 between the first inclined surface S1 and the length direction L of theslot section 111 is between 60 degrees and 80 degrees, and preferably, the included angle A1 is 75 degrees. An included angle A2 between the second inclined surface S2 and the length direction L of theslot 114 is between 10 degrees and 30 degrees, and preferably, the included angle A2 is 18 degrees. - With reference to
FIG. 6A andFIG. 6B again, when theadjustable strap 100 is tightened, the user pushes the slidingmember 120 in the length direction L toward a first direction (i.e., the right side ofFIG. 6A ) D1, so that the limitingmember 130 linked up with the slidingmember 120 drives the engagingmember 140 to move towards the first direction D1. In this process, since the included angle A2 is designed to be a smaller angle, the user is required to apply a relatively less force only to allow the engaging ends 142 to be released from the first inclined surface S1 and to slide along the second inclined surface S2, and force-saving is thus achieved. After thebody 110 is adjusted to apply the required tightness, the user stops pushing the slidingmember 120, the slidingmember 120 and the limitingmember 130 move to thesecond end 115 b of the throughhole 115, an elastic restoring force of the engaging ends 142 enables the engaging ends 142 to approach the engagingportion 116 and be propped against the closest first inclined surface S1, and that the adjustment process is completed. At this time, theslot section 111 and thecontrol section 112 are mutually locked. In a locked state, since the included angle A1 is designed to be greater than the included angle A2, the engaging ends 142 attached to the first inclined surface S1 are prevented from generating unnecessary sliding which may lead to detachment, so that fixation between theslot section 111 and thecontrol section 112 is ensured. When the user stops pushing the slidingmember 120, the engagingmember 140 may be instantly engaged with the engagingportion 116 to achieve fast locking. - The following provides further description describing how the
adjustable strap 100 of this embodiment is used. With reference toFIG. 5A andFIG. 5B again, when theadjustable strap 100 of this embodiment is to be loosened, the user pushes the slidingmember 120 in the length direction L toward a second direction (i.e., the left side ofFIG. 5A ) D2, so that the limitingmember 130 is driven to slide to thefirst end 115 a of the throughhole 115. The engaging ends 142 are forced to be deformed and thus are away from the engagingportion 116 at the same time when the limitingmember 130 slides and are drawn back into the limitingportion 134 at last. Since the engaging ends 142 are detached from the engagingportion 116, theslot section 111 and thecontrol section 112 may relatively slide freely. Since an engaging force between the engaging ends 142 and the engagingportion 116 is absent, theadjustable strap 100 is not subjected to a resistance force and may be loosened quickly. In this way, the user's demand for loosening theadjustable strap 100 easily is thereby satisfied. Compared to the prior art, additional pressing buttons, buckles, or other accessories for fixing are not required to be disposed on theadjustable strap 100 of this embodiment, so the number of parts is reduced and costs are thereby lowered. - As shown in
FIG. 2 andFIG. 3 , in this embodiment, theadjustable strap 100 further includes acrossover connection member 150. Theslot section 111 form hooks 118 at the two sides of theslot 114. Thecrossover connection member 150 crosses the two sides of theslot section 111 and is engaged with thehooks 118, so as to prevent the limitingmember 130 and the engagingmember 140 from being detached from thecontrol section 112, so that the limitingmember 130 and the engagingmember 140 are ensured to be secured in a direction perpendicular to the length direction L. In addition, thecrossover connection member 150 may also prevent theslot section 111 at the two sides of theslot 114 to be separated. In this embodiment, a number of thecrossover connection member 150 is exemplified as one, and a number of thehooks 118 is exemplified as three, but the application is not limited thereto. - With reference to
FIG. 2 andFIG. 4 together, in this embodiment, thecontrol section 112 has a stopping portion 117 located next to one end of theslot 114 away from thetail end 113 of theslot section 111 and configured to be in contact with a tail end of thecontrol section 112 to stop thecontrol section 112. When theadjustable strap 100 of this embodiment is adjusted, as the stopping portion 117 is disposed, the user is prevented from excessively pushing the slidingmember 120 to be detached from theslot 114. - In view of the foregoing, in the adjustable strap and the head mounted display device of the application, since the slot section and the control section are located at the two opposite sides of the body and adjustment and fixation can be made without additional pressing buttons, buckles, or other accessories for fixing to be disposed, and thus, the total number of parts is reduced and costs are further lowered. In addition, as the through hole is formed on the control section and the sliding member and the limiting member can slide between the first end and the second end of the through hole, the engaging ends are further driven to be away from or propped against the engaging portion, so that the slot section and the control section are controlled to relatively slide, and the body is therefore adjusted. Through the structural design between the slot section and the control section, the user only has to push the sliding member along the slot when using the adjustable strap provided by the application, and that adjustment and locking are completed at the same time, and convenient using experience is thus provided.
- It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed embodiments without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the disclosure covers modifications and variations provided that they fall within the scope of the following claims and their equivalents.
