Abstract
Blade sheath includes safety locks (36, 37) which are used for preventing blade (27) being drawn out from a fully inserted position of casing (1) of the blade sheath by accident. The safety locks can automatically act in response that the blade (27) inserts into the blade sheath, and it is better for the safety locks to couple with blade grinding mechanism (19) which can also respond the motion that the blade is inserted into or drawn out of the casing of the blade sheath. The blade grinding mechanism should not work during blade insertion, but works during blade is being drawn out. A manual operated loosen device (42) is equipped so as to loosen the lock and allow the blade to be drawn out. While the loosen device is operated, the blade must be drawn out of the blade sheath. The safety locks will fully loosen as the blade has been drawn out for a distance from the fully inserted position, afterwards, the operation of the safety locks can be finished so that the safety locks can not block blade from being drawn out. When the safety locks is fully working, blade clamping device (21) interacts with the blade for preventing the blade being drawn out, and the clamping device can be rotatably fitted to the casing of the blade sheath so that it can be shifted to or off the working position with the grinding mechanism.

As mentioned above and as shown in drawings blade scabbard 1 is operated as follows.
When blade scabbard 1 is ready to receive knife blade 27, sharpens device 20 and always be positioned at the position of rotating forward shown in Figure 8.For blade 27 is inserted passage 14, make the tip 53 (Figure 11) of blade extend through turnover perforate 13, pressing door 29.Be forced to along the direction of leaving perforate 13 around pivot 30 swings with back door 29, as shown in figure 12, thereby the bottom 54 of door 29 just rides on this knife back along the knife back 26 of blade 27.When blade 27 admission passages 14, blade 28 is positioned at sharpens recess 24, and engages with plate 23 under the bias effect of door 29.
Continuation is inserted passages 14 with blade 27 and is just made and sharpen device 20 and swing backward around pivot 60, thereby takes position shown in Figure 9, and each mobilizable interfacing part 36 engages upper surface or close this upper surface of the corresponding fixedly interfacing part 37 that cooperates in this position.Shown in customized configuration be characterised in that, when sharpening device 20 and be positioned at the position of Fig. 9, sharpen disabling device 21 and just engage knife-blade 28, the following describes the result of this joint.
In customized configuration as shown in the figure, interfacing part 36 as shown in Figure 9 and 37 relative position remain to blade 27 and reach insertion position shown in Figure 10.At this moment, sharpen the space 59 (Figure 11) that disabling device 21 is crossed knife-blade 28 and is exposed to blade 27 bent angles 57 back.As a result, when sharpening device 20 and further rotate backward under pressure, sharpen disabling device 21 and just upwards move on in the space 59, this pressure is acted on by the knife blade 27 that moves inward and sharpens on the disabling device 21.The further rotation of device 20 causes the inclined plane 40 of each interfacing part 36 to engage the top edge of rib 50, and this rib 50 forms the corresponding interfacing part 37 that cooperates, as shown in figure 14.Because this joint, each arm 38 gradually to intrinsic deflection, thereby rides on the corresponding cooperation interfacing part 37 interfacing part 36 with respect to another.Reach a position at last, each interfacing part 36 can outwards move under the partial pressure of respective arms 38 in this position, make the lock face 39 of interfacing part 36 be positioned at interfacing part 37 following and relative of corresponding cooperation, shown in Figure 10 and 15 with the lock face 55 of this interfacing part 37.Therefore sharpening device 20 is pinned effectively and can not be rotated away from position shown in Figure 10 forward.
When sharpening device 20 and be positioned at the position that rotates backward shown in Figure 9, sharpen the blade 28 that disabling device 21 engages blade as previously mentioned.This joint blade 27 applies a power that makes progress, and makes blade 28 not engage with sharpening plate 23, or has limited the pressure between blade 28 and plate 23 at least.
Shown in customized configuration in, sharpen device 20 and can take position shown in Figure 9 in early days, and during blade 27 continues to insert blade scabbards 1, keep this position what blade 27 inserted blade scabbards 1.During when the position of blade 27 arrival maximum insertion blade scabbard 1 as shown in figure 10 or near this position, the strangulation device is had an effect.
The strangulation device can be got any suitable form and can operate in any suitable manner.Shown in customized configuration in, the strangulation device comprises to be sharpened disabling device 21 or forms and utilized the rotation of sharpening device 20 by sharpening disabling device 21, but in other configuration, it can with sharpen disabling device 21 and sharpen in the mechanism 19 one or two and separate, and be independent of one of them or two and operate.In addition, the strangulation device not necessarily depends on as mentioned above and rotates, and can depend on for example linear movement.Shown specific strangulation device cooperates (Figure 11) with the bent angle 57 of knife blade 27, and Figure 10 illustrates the mode of this cooperation.
Can find out obviously that from Figure 10 blade 27 is so shaped that the bent angle 57 of blade 27 inserts passage 14 is positioned at roller 56 up to small part ground back fully at blade 27.At the same time, under the bias effect of door 29, blade 27 can be to decline, but this situation not necessarily takes place, and if take place then preferably remain on minimum degree.It is desirable to, when roller 56 entered the position of Figure 10, blade 27 can not raise and leave roller 56, for this purpose, utilized the joint between the upper edge of blade upper edge 26 and perforate 13 to limit moving upward of blade 27.
Can see obviously that from top explanation bent angle 57 and roller 56 cooperate the firm braking action of formation and can not extract blade 27 out.Door 29 bias effect helps to keep the stacked of bent angle 57 and roller 56, because it pushes blade 27 diapire 7 of blade scabbard main body 2 to, but this help preferably is not significant feature in the mode of operation that keeps the strangulation device.Constitute the perforate 13 and 47 of guider parts, its size preferably can stop or prevent the bias effect of blade 27 opposing doors 29 and excessively raise, so that break away from the strangulation effect of roller 56.
When needs unclamp blade 27, when extracting out from blade scabbard 1, the user contacts two pressing pieces 51, and as shown in figure 16, inwardly it is exerted pressure opposite to each other, meanwhile hilt 58 is applied an outside pulling force.Adopt customized configuration shown in the drawings, the user need contact pressing piece 51 with a hand usually, and with the another hand hilt 58 is applied pulling force.The inside motion of pressing piece 51 causes the lower part 48 of each parts to engage the outer end portion 41 of a corresponding docking arm 38 and make this part 41 corresponding inside motions.Interfacing part 36 is thrown off the locking joint of its corresponding cooperation interfacing part 37 gradually as a result, and back-off assembly 20 thus, make to be with its roller 56 to swing forward around pivot 60.
When throwing off its locking joint, the interfacing part 37 of interfacing part 36 and cooperation must blade 27 apply outside pulling force.Even in order to make device 20 turn to the degree that interfacing part 36 and 37 is not also rejoined when pressing piece 51 is removed pressure forward, this is necessary.Require these two kinds independently operations, add the reliability of blade scabbard safety lock, reduced child takes out the knife blade from blade scabbard possibility to greatest extent.
Pull out blade 27 and cause device 20 to swing to its forward most position as shown in Figure 8, in this position, this device 20 just in the known manner the blade 28 of blade carry out it and sharpen effect.Can know from Fig. 8 and to find out that roller 56 breaks away from the blade 28 of blades, plays effect and sharpen device 20, and blade is sharpened.
Will be appreciated that from above-mentioned explanation, can extract relevant blade easily out with blade scabbard of the present invention, and can prevent to extract out absent-mindedly or by mistake blade at the same time.
Various changes, remodeling and/or interpolation can be carried out and without prejudice to the spirit or scope of the present invention of determining by appended claims in said structure and component configuration.
